Is Human Genetic Modification Good Or Bad
Is human genetics modification a key issue for the human being?
Human Genetic Modification any alteration of genetic material, as in agriculture, to make them
capable of producing new substances or performing new functions. In today's society there's a
conflict between how Human genetics is a dangerous development or how it's a positive
progress.Human genetics is a dangerous development for the reason that lots of people are changing
defects that embryos might have and cause a grater defect. Scientist have said that human genetic
modification on an embryo can cause damage and that they will have to end up killing the embryo.
Designer babies have caused a conflict between if it's good or bad to have a baby with different
genetics. Human genetic modification has caused lots of problems between scientists and parents

Lots of people have changed parts of their babies genes."Some people object to genetic
enhancement on religious or philosophical grounds". Opening the door to one kind of genetic
modification, makes people likely more prone to opening it to all kinds of modifications. Permitting
human genetic modification for any reason would likely lead to its escape from regulatory limits for
enhancement purposes, and to the emergence of a market–based modification that would exacerbate
already existing discrimination, inequality, and conflict. Human civilization should not risk these
outcomes in the article Designer Babies by Gale, a Cengage Company From Opposing Viewpoints

Genetic Counseling Paper
Genetic counseling is for older child bearing mothers seeking counseling for the best course to take
with giving birth. In most cases this is for older women who are becoming mothers. It is common
that the baby could be born with a hereditary disorder and genetic problems due to the mothers high
chromosomal abnormalities. As a young mothers pregnancy it is 1 in every 200 pregnancies to have
this problem, for older mothers the rate is 1 in every 20 pregnancies. (schonberg&tifft, 2007) Some
disorders for the baby are common and controllable, such as blood disorders. But there is also high
risk of premature birth or miscarriage. These extra genes include diseases like cystic fibrosis,

Essay about Love
Love Love is difficult to define, difficult to measure, and difficult to understand. Love is what great
writers write about, great singers sing about, and great philosophers ponder. Love is a powerful
emotion, for which there is no wrong definition, for it suits each and every person differently.
Whether love is between family, friends, or lovers, it is an overwhelming emotion that can be
experienced in many different ways. People experience love for the first time by being part of a
family. Family love is demonstrated through lessons of sacrifice, concern and compassion, from the
cradle to the grave. There are many different levels and conditions of family love. It is the love we

A close–knit loving bond between two people can begin with a friendship. Whether it is a friendship
between two males, two females, or one male and one female, these friendships will develop into
love. In no way is it a romantic love, but this type of love connects and bonds friends. Friends may
move away or friendships may wane, but the love between the two people burns on forever.
Romantic love is a love that not every person will experience. It is a type of love that is not there at
the beginning, but grows within the individual. When one finally finds the love they have been
looking for, one can not imagine life with anybody else. Romantic love is a connection between two
souls that is captured with a feeling that is not only felt within the heart but within their body as
well. I have never been in love with a girl; I can only imagine what it might be like to be in love.
Guessing from my sister's relationship with boys, it seems like a big headache instead of a
wonderful feeling. To simply write a definition of love is complicated because every person has a
different perception of love. The only way to capture the true meaning of love is to experience the
feeling and find out for oneself, what love is. In our lives and the lives of others, love is evident.

Down 's Syndrome : A Common Chromosomal Disorder
Down's syndrome is a common chromosomal disorder effecting the physical and cognitive
development of a person. An individual with Down's syndrome typically has numerous health
ailments, which require intense medical care and create great medical costs. A person with Down's
syndrome requires special schools and invasive therapies, which can also be costly. Many believe
people with Down's syndrome do not live a fulfilled life, compared to a typical person because
many cannot live independently or be successful in life. To avoid costly expenses and endless time
and effort to help a Down's person be happy and healthy, many believe it's best to terminate a
Down's syndrome pregnancy to avoid dealing with all the hardships and issues that may arise. Some
families cannot handle the emotional and financial hardships. Not only can living with Down's

Heart Abnormalities: Critical Congenital Heart Defects
Critical Congenital Heart Defects are abnormalities of the heart structure that are present at birth.
These occur because of incomplete or abnormal development of the fetus' heart. These defects can
cause severe mortality within the newborn stage (Goldstein, 2013, p.1). Several are known to be
linked to genetic disorders such as Down syndrome and others are thought to be linked to
environmental factors that women can be exposed to while pregnant. The cause of most CCHD's is
unknown.
Symptoms of significant heart defects include but are not limited to, rapid breathing, difficulty
feeding, and blueness in the lips, excessive sweating, and fatigue. A common feature of many forms
of congenital heart disease is hypoxemia.
Newborns with CCHD are susceptible to serious and sudden worsening clinical status, in the first
days and weeks of life. Some babies born with a heart defect may appear healthy at first and are sent
home with their families before their heart defect is detected. It is estimated that about 300 infants
with an unrecognized Critical congenital heart defect (CCHD) are discharged each year from
newborn nurseries in the United States. These babies are at risk of having serious complications and
often require emergency care. That is why screening and follow–up treatment are so vital. Newborn

is a hole that occurs between the left and right pumping chambers of the heart.
This ventricular defect occurs because of problems in the early development of the heart. There is no
clear cause of a ventricular septal defect but most doctors think that genetics play a role. It's a very

Gene therapy is a potential approach to the treatment of genetic disorders in humans. This is a
technique where the absent or faulty gene is replaced by a working gene, so the body can make the
correct enzyme or protein and consequently eliminate the root cause of the disease (BIO, 1990).

And also how do you make the delivery specific and safe? The first step in gene therapy is an
accurate diagnosis of the genetic defect. This is done by using a DNA probe. The DNA probe is
specific to a complementary piece of DNA. This technique using DNA probes is more specific then
other conventional methods of diagnosing genetic defects in humans (BIO, 1990). After the correct
diagnosis is made, healthy DNA can be inserted into a virus, which has had infectious genes stripped
out of it. The virus is then mixed with cells taken out of a patient and then injected back into that
patient. Viruses are used because they are like genes, but wrapped in a special protein coat. On the
surface of this protein coat are specialized proteins that bind to the surface of cells. Once these
viruses are in the body they lock in place on specific cells. The cells then suck the viruses in or the
viruses force their way into the cells (PBS).
A retrovirus is a type of virus that is used in gene therapy. This is a virus that inserts its genetic code
directly into the chromosomes of the host cell (PBS). Other viruses are used for different kinds of
genetic problems. One of these is the adenovirus which is used for cystic fibrosis patients (Coutts,

ABSTRACT
New materials with distinctive properties are arising and attracting the scientific community at
regular intervals. Stiffness and strength are the important factors in determining stability and
lifetime of any technological devices, but defects which are inevitable at the time of production can
alter the structural properties of any engineering materials. Developing graphene with specific
structural properties depends upon controlling these defects, either by removing or deliberately
engineering atomic structure to gain or tailoring specific properties. In the present article, a
comprehensive review of defective graphene sheets with respect to its mechanical and thermal
properties are presented and examined.
Key Words: Graphene; point defects; line defects; molecular dynamics; atomistic modeling; fracture
toughness. Introduction
Graphene is emerging as a potential candidate for developing nanocomposites with desired
mechanical properties, thermal and electrical conductivities. Due to its exceptional mechanical
properties, thermal and electrical conductivities graphene can also be used for more conventional
purposes as compared to carbon nano tubes, which is

Around 5300 babies with Down syndrome are born in the United States each year, and
approximately 200,000 people in this country have the condition. (de Graaf G, Buckley F, Skotko

born each year is alarming. Despite the fact that Down syndrome can be detected before birth, there
is no known way to cure it. As such, the parents whose child have been diagnosed to have Down
syndrome have to decide whether to keep the child or not.
Parenting has never been easy, and it is made harder if the child is affected by Down syndrome.
Most of the time, when parents are informed that their child has Down syndrome, they are stricken
with grief, depression, hopelessness, and the likes. (Preidt, 2010). Having a child affected by such
mental illnesses may make it hard for parents to deal with their children, since any shortcomings
may lead to a miserable life for their child. But even with Down syndrome, a child is still a child,
and can still be brought up to live a happy life if parented correctly.

who are not aware of what they go through. The researchers seek to improve the general knowledge

Tetralogy Of Fallot Essay
What is Tetralogy Of Fallot?
The definition of TOF reads, a type of congenital heart defect. Congenital means that it is present at
birth (UMMC, 2013). TOF occurs when there is 4 abnormalities all together. One of the 4
abnormalities is when a massive hole is in the wall of the muscle (septum) that separates the 2
bottom pumping cambers (ventricles) of the heart. The massive hole in the abnormality itself is a
VSD. A VSD is known as a Ventricular Septal Defect. Due to the location of the VSD, two more
abnormalities develop. One being that there is a vast blood vessel which take the blood to the body
(aorta) is pulled toward, and "overrides" the ventricular septum so that it sits over both the left and
right ventricles; this is called an overriding aorta (UMMC, 2013). The second abnormality that takes
place is that the muscle produces obstruction to the blood flow going out the right across the
pulmonary valve. The right ventricular outflow tract obstruction, can be due to obstruction below
the valve, at the valve or in the pulmonary arteries as they deliver blood out to the lungs (UMMC,
2013). There is different severities of TOF. The most acute form is known as pulmonary atresia. In
patients with pulmonary atresia there is no functional pulmonary valve. The right ventricular
outflow obstruction leads to thickening of the ... Show more content on Helpwriting.net ...
Medical studies report that there is no known cause of TOF. There is some things that can be seen in
TOF babies but not the diffident cause. Such as, low oxygen levels, narrowing of the pulmonary
outflow tract, thickened wall of the right ventricle and a VSD. However, there are a few genetic
syndromes that have been reported. Such as, Down syndrome or DiGeorge syndrome (UMMC,
2013). To add to that, most people with TOF do not have genetic syndromes. Tetralogy Of Fallot

The Genetic Defect Albinism In the past, albinos were usually treated with fear or awe. They were

An alteration of the gene for dopachrome tautomerase does not produce albinism. Three other genes
make proteins that are also involved in melanin pigment formation and albinism, but the exact role
of these proteins remains unknown. These genes are the P gene on chromosome 15, the
Hermansky––Pudlak syndrome gene on chromosome 10, and the ocular albinism gene on the X
chromosome. The gene carrying the defect that produces albinism is recessive, which means that
both parents must carry this recessive gene in order to produce a child with the condition. When
both parents carry the gene (and neither has albinism), there is a one in four chance with each
pregnancy that their child will have albinism. The inheritance pattern of ocular albinism is alittle
different. This condition is X–linked, meaning that the recessive gene for ocular albinism is located
on the X chromosome. X–linked ocular albinism appears just about only in males who inherit the
condition from their mothers. Albinism is a recessive inherited defect in melanin metabolism in
which pigment is absent from the hair, skin, and eyes (oculocutaneous albinism) or just from the
eyes (ocular Albinism). Albinos tend to be children of parents who were first cousins. For a long

HIGHLIGHTS
ABSTRACT
Structural defects which are inevitable during the production, chemical and heat treatment processes
can affect the mechanical properties of graphene and also defects can be deliberately introduced in
graphene by ion beam irradiation to get required properties for specific applications. So,
understanding the effect of defects on mechanical properties and failure behaviours of a graphene
sheet is important for its applications. In this work, the effects of linear and angular orientation of
different types of Stone–Thrower–Wales (STW–1 and STW–2) defects on the mechanical properties
and failure behaviour of graphene membrane have been investigated in the frame of molecular
dynamics. This work discussing about tuneable mechanical properties by amending the linear
orientation of STW–1 and STW–2 defects at different angles in zigzag direction and armchair
direction respectively. The results obtained from the present work may provide the insights in
tailoring the mechanical properties by preparing defects in graphene, and give a full picture for the
applications of graphene with defects in flexible electronics and nanodevices.

Children with DS often grow slowly and as they become an adult they are shorter than normal. Their
neck can have excess fat and skin which makes it look shorter than normal. Short, stocky arms and
legs along with a wide space between the big toe and second toe is also a physical body symptom.
As for face shapes and features they can have slanted eyes, nasal bridge that looks pushed in, small
ears that look low on the head, irregularly shaped mouth and tongue. A child's tongue can partly
stick out and the teeth can come in late and in a different order than other children. Most children
with DS have mild to moderate cognitive disabilities such as impulsive behavior, short attention
span and slow learning capabilities. Some health issues that are often symptoms of DS are heart

ABSTRACT:
The mechanical properties of graphene sheet can be tailored with the help of topological defects. In
this research article, the effects of Stone–Thrower–Wales (STW) defects on the mechanical
properties of graphene sheet was investigated with the help of molecular dynamics (MD) based
simulations. Authors has made an attempt to analyse the stress field developed in and around the
vicinity of defect due to bond reorientation and further systematic evaluation has been carried out to
study the effect of these stress fields against the applied axial compressive load. The results obtained
with the pristine graphene were made to compare with the available open literature and the results
were reported to be in good agreement with theoretical and experimental data. It was predicted that
graphene with STW defect cannot able to bear compressive strength in zigzag direction, whereas on
the other hand it was predicted that graphene sheet containing STW defect can bear higher
compressive load in armchair direction, which shows an anisotropic response of STW defects in
graphene. From the obtained results it can be observed that orientation of STW defects and the

Essay On Birth Defect
Not every birth in this world is perfect, unfortunately. One out of every 33 babies born in the United
States has some form of birth abnormality according to the CDC. Sometimes mutations and birth
defects can occur. Of course, no mother would ever want a child with a birth defect. So how do
these birth defects and problems occur? Basically anything a mother does to her body will also have
a direct effect on the developing fetus inside. Simply put it, a teratogen is defined as "any agent that

Birth defects usually break down into two categories: genetic and non–genetic causes. During
conception, half of the mother's and father's chromosomes come together to form the genetic
blueprint for the future child. However, sometimes the parents may carry a form of genetic defect
that they may not be aware of. Perhaps the defect has been carried down in the family from
generation to generation, but just hasn't emerged yet. These defects are established at birth and often
cannot be prevented (Selner & Leord, 2012). An example of a genetic birth defect would be Down
syndrome. This occurs roughly 1 in 800 births, making it one of the most common chromosomal
disorders. Down syndrome is caused by the presence of three copies of the 21st chromosome. One
of the biggest causes attributed to Down syndrome has to do with the mother's maternal age.
According to Lobo and Zhaurova (2008), the risk of having a child with the condition exponentially
increases after the woman reaches age 35. In young mothers, the risk of having a child with Down
syndrome is 1 in 2,000, but the frequency rises to 1 in 100 when a woman is 40, and 1 in 12 when

ABSTRACT
Structural defects which are inevitable during the production, chemical and heat treatment processes
can affect the mechanical properties of graphene and also defects can be deliberately introduced in
graphene by ion beam irradiation to get required properties for specific applications. So,
understanding the effect of defects on mechanical properties and failure behaviours of a graphene
sheet is important for its applications. In this work, the effects of linear and angular orientation of
different types of Stone–Thrower–Wales (STW–1 and STW–2) defects on the mechanical properties
and failure behaviour of graphene membrane have been investigated in the frame of molecular
dynamics. This work discussing about tuneable mechanical properties by amending the linear
orientation of STW–1 and STW–2 defects at different angles in zigzag direction and armchair
direction respectively. The results obtained from the present work may provide the insights in
tailoring the mechanical properties by preparing defects in graphene, and give a full picture for the
applications of graphene with defects in flexible electronics and nanodevices.

Genetic Defects in Cystic Fibrosis Transmembrane...
Abstract: The main goal of this paper is to explain what Cystic Fibrosis is and also to explain what
the causes of Cystic Fibrosis are. Cystic Fibrosis is caused by a mutation in a gene called Cystic
Fibrosis Transmembrane Conductance Regulator (CFTR). Cystic Fibrosis is known as one of the
most common life–shortening disease. More that 1,000 mutations in the CFTR gene have been
found in people with Cystic Fibrosis. Most of these mutations change single protein amino acids in
the CFTR protein and it deletes a small amount of DNA from the CFTR gene. I am going to explain
what happens when the CFTR proteins is functioning normally and when it is diseased.

Ion channels are pore forming proteins which allow the passage of ions that are charged into and out
of the cell down the electrochemical gradient [4]. Electrochemical gradient is a change in an ion that
represents a type of potential energy that accounts for the both concentration and the membrane
potential [1]. The channel transports particles called chloride ions. Chloride ions are formed when
the element chlorine picks up one electron to form an ion. Chlorides ions help keep the movement of
water in tissues and maintain the fluidity of mucus and other secretions [3].

When the protein is diseased, that causes people with Cystic Fibrosis to have digestive problems.
The mucus can block the ducts of the pancreas, and that prevents the enzymes from reaching the

other is such that if one suffers in pain, his suffering and pain touches rest of the humanity. It is now
in our domain to use this new technology called "Genetic Engineering" to ameliorate human
suffering and pain. We should make sure that this technology is only used for the betterment of
human species and not selectively. It is indeed horrifying to know that someone wants to use this as
a tool for eugenics or to alter the human race altogether. I totally agree with the specter mentioned in
the book Babies by Design by Ronald M. Green (2007), that in case a human weakness has been
eliminated through genetic engineering, and the few parents who opt for a "natural" conception run
the risk of producing low quality "invalids"––––who become members of a despised under–class. I

ABSTRACT
Structural defects are inevitable in graphene due to its production techniques as well as chemical
and heat treatment processes. These defects in graphene are introduced either during the production
process or deliberately by us to tailor its properties. In this article, the effect of nearest neighbour
distance and angular orientation between Stone–Thrower–Wales defects (STW–2) on the
mechanical properties and failure morphology of graphene was investigated in the frame of
molecular dynamics. Mechanical properties and failure morphology of graphene was predicted to be
the function of angular orientation between STW–2 defects, when the nearest neighbour distance
was in the range of 10 Å. Graphene sheet containing pair of STW–2 defects had shown an overall
increase of 8% and 11% in fracture strength and strain respectively as compared to graphene with
single STW–2 defect. This study also characterised the failure morphology of graphene sheet with
single and pair of STW–2 defects in the armchair direction.

Some heart may reappear again in adulthood even if the defect is treated during childhood. This
tends to happen because rarely are heart defects actually cured. They are repaired so that the heart
function is improved but it usually does not make it completely normal. Many reasons that
congenital heart defects re–emerge is because often the treatment received during childhood was
successful but later in life it worsens. Another possible reason is that the defect was not bad enough
to need to be treated when the person was a child but has gotten worse over time and now requires
treatment. Currently congenital heart disease is not preventable but if the mother avoids alcohol and

Because dry rot thrives in damp unventilated areas like floorboards and behind wood panelling most
of the time the damage is done before that fungus is discovered.
How to spot dry rot, initially the fungus appears as off–white felt–like or cotton–wool like sheets on
brickwork and timber and in later stages can develop fungal strands as thick as your finger. Where
the fungus is exposed to light it often has a lemon–yellowish colour. Damage is often confined to
timber but large flat mushroom–like fruiting bodies can easily grow through finishes such as plaster
or paint. These fruiting bodies may be the first visible sign of a problem, and they produce numerous
spores which are normally brick–red in colour. Entirely dry–rot decayed timber can be crumbled
between your fingers. The fungus leaves deep cracks running across the grain, and there is often
evidence of off–white sheets of the fungus on the wood. Also the brick–red spores that it can leave
can grow on their own on a new piece of timber if the conditions are right. We can also look at dry
rot at the molecular level, structural level, and engineering level. When we look at dry rot at the

Arguments for abortion
Despite assurances, the risk for fetal defects due to chromosomal aberration remains, physically
(tallness, low fertility, infertility, and breast enlargement), mentally (potential manic–depressive
problems), and behaviorally (tendency towards behavioral disorders). Purdy (1995) argued that
every child should be provided with at least a minimally satisfying life, and genetic defect and its
physical, mental and behavioral consequences cannot provide that level of satisfying life. Otherwise,
the child will be socially outcast among the "defectives," she will feel unloved, feels resentment for
the short end that her birth had given her. The mother also will blame herself for giving birth to her,
watching her suffer from such burdensome conditions. Her descendants too will be burdened with
her genetic defects and the resultant woes. Purdy (1995) also insisted that, until there are assurances
and certainties that the risks are not going to happen, it is the moral duty of the mother to not bring
defective babies into the world, and burden the society for their care.
Lippman (1991) noted that people do not believe society has an obligation to adjust their lives to the

Genetic Defects Of Gene Therapy
Gene therapy is a process involving the transplant of non–mutant, normal genes into cells, either in
place of missing genes, or to essentially replace those genes which are not functioning properly, or
not coding for properly functioning proteins, with the purpose of treatment and correction of a
number of genetic disorders. This particular type of treatment technique is hoped to, in the future, be
able to replace surgery, and a slew of different drugs in the treatment of a variety of diseases in
humans caused by genetic defects. This seems to be a promising technique with the potential to

to effectively "treat" the disorder. Another question is, what clinical diseases and disorders would
this treatment be appropriate for, in addition, which disorders have been attempted to be treated with
this technique already, and have there been any successes with this treatment technique. Finally,

heredity, discovered by Gregor Mendel (also known as the father of genetics) and his pea plants
experiment. In Mendel's experiment "he described the unit of heredity as a particle that does not
change and is passed on to offsprings" (Mandal). This means that a living being gets half of their
genes from one parent and the other half from the second parent. These genes are what get modified
in designer babies. The term designer babies is the media's name for eugenics. Eugenicists believe
that it is in our society's best interest to encourage families with "good genes" to reproduce, and to
condemn the "unfit" families. These genetically modified children are considered as the "new

Rubinstein-Taybi Syndrome
There are over 5,000 genetic disorders passed down through the generations. These disorders are

manufacturer to seek another buyer at a reduced rate. Over time organizations have invested a large
amount of time and money to track and manage non–conformances by implementing processes and
procedures to assist in reducing or preventing the amount written.
Throughout the aerospace industry nonconformances defined is a product or service does not adhere
to a process or procedure affecting the quality of service (quality systems, 2015). A
Nonconformance record (NCR) documents in detail an identified defect or discrepancy through the
use of a centralized database or company internal program so that the information can be reviewed

Human Genetic Modification any alteration of genetic material, as in agriculture, to make them capable of producing new substances or performing new functions. In today's society there's a conflict between how Human genetics is a dangerous development or how it's a positive progress.Human genetics is a dangerous development for the reason that lots of people are changing defects that embryos might have and cause a grater defect. Scientist have said that human genetic modification on an embryo can cause damage and that they will have to end up killing the embryo.

Opening the door to one kind of genetic modification, makes people likely more prone to opening it to all kinds of modifications. Permitting human genetic modification for any reason would likely lead to its escape from regulatory limits for enhancement purposes, and to the emergence of a market–based modification that would exacerbate already existing discrimination, inequality, and conflict. Human civilization should not risk these outcomes in the article Designer Babies by Gale, a Cengage Company From Opposing Viewpoints In Context states, "The creation of genetically modified human embryos raises many ethical questions".

Love is what great writers write about, great singers sing about, and great philosophers ponder. Love is a powerful emotion, for which there is no wrong definition, for it suits each and every person differently. Whether love is between family, friends, or lovers, it is an overwhelming emotion that can be experienced in many different ways. People experience love for the first time by being part of a family. Family love is demonstrated through lessons of sacrifice, concern and compassion, from the cradle to the grave. There are many different levels and conditions of family love.

Whether it is a friendship between two males, two females, or one male and one female, these friendships will develop into love. In no way is it a romantic love, but this type of love connects and bonds friends. Friends may move away or friendships may wane, but the love between the two people burns on forever. Romantic love is a love that not every person will experience. It is a type of love that is not there at the beginning, but grows within the individual. When one finally finds the love they have been looking for, one can not imagine life with anybody else. Romantic love is a connection between two souls that is captured with a feeling that is not only felt within the heart but within their body as well. I have never been in love with a girl; I can only imagine what it might be like to be in love. Guessing from my sister's relationship with boys, it seems like a big headache instead of a wonderful feeling. To simply write a definition of love is complicated because every person has a different perception of love. The only way to capture the true meaning of love is to experience the feeling and find out for oneself, what love is. In our lives and the lives of others, love is evident.

An individual with Down's syndrome typically has numerous health ailments, which require intense medical care and create great medical costs. A person with Down's syndrome requires special schools and invasive therapies, which can also be costly. Many believe people with Down's syndrome do not live a fulfilled life, compared to a typical person because many cannot live independently or be successful in life.

  • 11. Heart Abnormalities: Critical Congenital Heart Defects Critical Congenital Heart Defects are abnormalities of the heart structure that are present at birth. These occur because of incomplete or abnormal development of the fetus' heart. These defects can cause severe mortality within the newborn stage (Goldstein, 2013, p.1). Several are known to be linked to genetic disorders such as Down syndrome and others are thought to be linked to environmental factors that women can be exposed to while pregnant. The cause of most CCHD's is unknown. Symptoms of significant heart defects include but are not limited to, rapid breathing, difficulty feeding, and blueness in the lips, excessive sweating, and fatigue. A common feature of many forms of congenital heart disease is hypoxemia. Newborns with CCHD are susceptible to serious and sudden worsening clinical status, in the first days and weeks of life. Some babies born with a heart defect may appear healthy at first and are sent home with their families before their heart defect is detected. It is estimated that about 300 infants with an unrecognized Critical congenital heart defect (CCHD) are discharged each year from newborn nurseries in the United States. These babies are at risk of having serious complications and often require emergency care. That is why screening and follow–up treatment are so vital. Newborn screening and follow up is seen as a public health role. In order to perform this role, effectively partnerships are required between hospitals, clinical and ...

The ventricular septal defect is a hole that occurs between the left and right pumping chambers of the heart. This ventricular defect occurs because of problems in the early development of the heart. There is no clear cause of a ventricular septal defect but most doctors think that genetics play a role.

With gene therapy this all could be reality in the near future. Gene therapy is a potential approach to the treatment of genetic disorders in humans. This is a technique where the absent or faulty gene is replaced by a working gene, so the body can make the correct enzyme or protein and consequently eliminate the root cause of the disease (BIO, 1990). There are two types of gene therapy treatment: Somatic cell gene therapy and germline therapy. Somatic cell gene therapy involves obtaining blood cells from a person with a genetic disease and then introducing a normal gene into the ... Show more content on Helpwriting.net ... And also how do you make the delivery specific and safe? The first step in gene therapy is an accurate diagnosis of the genetic defect. This is done by using a DNA probe. The DNA probe is specific to a complementary piece of DNA. This technique using DNA probes is more specific then other conventional methods of diagnosing genetic defects in humans (BIO, 1990). After the correct diagnosis is made, healthy DNA can be inserted into a virus, which has had infectious genes stripped out of it. The virus is then mixed with cells taken out of a patient and then injected back into that patient. Viruses are used because they are like genes, but wrapped in a special protein coat. On the surface of this protein coat are specialized proteins that bind to the surface of cells. Once these viruses are in the body they lock in place on specific cells. The cells then suck the viruses in or the viruses force their way into the cells (PBS). A retrovirus is a type of virus that is used in gene therapy. This is a virus that inserts its genetic code directly into the chromosomes of the host cell (PBS). Other viruses are used for different kinds of genetic problems. One of these is the adenovirus which is used for cystic fibrosis patients (Coutts, 1998). To use a virus in gene therapy, the patient's immune system has to be weakened so it will not fight off the virus. If weakening the patient's immune system is not ... Get more on HelpWriting.net ...

Graphene Essay Effect of Point and Line Defects on the Properties of Graphene: A Review Rajasekaran G, Prarthana Narayanan and Avinash Parashar* Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee – 247667, India * Corresponding author: E–Mail: drap1fme@iitr.ac.in, Ph: +91–1332–284801 ABSTRACT New materials with distinctive properties are arising and attracting the scientific community at regular intervals. Stiffness and strength are the important factors in determining stability and lifetime of any technological devices, but defects which are inevitable at the time of production can alter the structural properties of any engineering materials. Developing graphene with specific structural properties depends upon controlling these defects, either by removing or deliberately engineering atomic structure to gain or tailoring specific properties. In the present article, a comprehensive review of defective graphene sheets with respect to its mechanical and thermal properties are presented and examined. Key Words: Graphene; point defects; line defects; molecular dynamics; atomistic modeling; fracture toughness. Introduction Graphene is emerging as a potential candidate for developing nanocomposites with desired mechanical properties, thermal and electrical conductivities. Due to its exceptional mechanical properties, thermal and electrical conductivities graphene can also be used for more conventional purposes as compared to carbon nano tubes, which is ...

However, not all people are gifted with a perfectly normal genetic structure. A person may suffer from genetic defects, which are irregularities in the genome. In the field of biology, genetic aberrations are not rare cases. According to a surveillance system called Metropolitan Atlanta Congenital Defects Program, genetic birth defects, affect approximately 3% of childbirths in the United States.

Around 5300 babies with Down syndrome are born in the United States each year, and approximately 200,000 people in this country have the condition. (de Graaf G, Buckley F, Skotko BG, 2016). While Down syndrome cannot be inherited, the number of babies with Down syndrome born each year is alarming. Despite the fact that Down syndrome can be detected before birth, there is no known way to cure it. As such, the parents whose child have been diagnosed to have Down syndrome have to decide whether to keep the child or not. Parenting has never been easy, and it is made harder if the child is affected by Down syndrome. Most of the time, when parents are informed that their child has Down syndrome, they are stricken with grief, depression, hopelessness, and the likes. (Preidt, 2010). Having a child affected by such mental illnesses may make it hard for parents to deal with their children, since any shortcomings may lead to a miserable life for their child. But even with Down syndrome, a child is still a child, and can still be brought up to live a happy life if parented correctly. This study aims to relay the experiences of a parent who has a child with Down syndrome to people who are not aware of what they go through.

  • 27. Tetralogy Of Fallot Essay What is Tetralogy Of Fallot? The definition of TOF reads, a type of congenital heart defect. Congenital means that it is present at birth (UMMC, 2013). TOF occurs when there is 4 abnormalities all together. One of the 4 abnormalities is when a massive hole is in the wall of the muscle (septum) that separates the 2 bottom pumping cambers (ventricles) of the heart. The massive hole in the abnormality itself is a VSD. A VSD is known as a Ventricular Septal Defect. Due to the location of the VSD, two more abnormalities develop. One being that there is a vast blood vessel which take the blood to the body (aorta) is pulled toward, and "overrides" the ventricular septum so that it sits over both the left and right ventricles; this is called an overriding aorta (UMMC, 2013). The second abnormality that takes place is that the muscle produces obstruction to the blood flow going out the right across the pulmonary valve. The right ventricular outflow tract obstruction, can be due to obstruction below the valve, at the valve or in the pulmonary arteries as they deliver blood out to the lungs (UMMC, 2013). There is different severities of TOF. The most acute form is known as pulmonary atresia. In patients with pulmonary atresia there is no functional pulmonary valve. The right ventricular outflow obstruction leads to thickening of the ... Show more content on Helpwriting.net ... Medical studies report that there is no known cause of TOF.

Jaelyn's parents learned about her condition called Ebstein's Anomaly during a fetal echocardiogram when her mother was only 30 weeks pregnant. The doctors and nurses at Cardinal Glennon Children's Hospital monitored Jaelyn in–utero to watch for hydrops (heart failure) and other indications her heart disease was affecting her growth. Jaelyn went into heart failure just five weeks later when her mother was only 35 weeks pregnant. She was given a 5% chance of survival due to the severity of her defect. The family was also told Jaelyn would not survive past her first birthday; she turns five in March. When Jaelyn was born, her entire family was afraid she wouldn't survive the delivery, but thankfully, Jaelyn's story is a true miracle. When the doctors see Jaelyn during routine checkups and physician visits, they can't believe she has Ebstein's Anomaly because for how far she has come and how healthy she looks.

Albino births were common enough in some groups not to cause any excitement. For example, among the San Blas Indians of Panama, one in approximately 130 births is an albino. In the mid–nineteenth century, albinos were exhibited in sideshows. Whole families were displayed at times and were described as a unique race of might people. They were said to live underground and to come out only at night when the light was dim and would not hurt their eyes. Albinism is a genetic defect if the integumentary system.

An alteration of the gene for dopachrome tautomerase does not produce albinism. Three other genes make proteins that are also involved in melanin pigment formation and albinism, but the exact role of these proteins remains unknown. These genes are the P gene on chromosome 15, the Hermansky––Pudlak syndrome gene on chromosome 10, and the ocular albinism gene on the X chromosome. The gene carrying the defect that produces albinism is recessive, which means that both parents must carry this recessive gene in order to produce a child with the condition. When both parents carry the gene (and neither has albinism), there is a one in four chance with each pregnancy that their child will have albinism. The inheritance pattern of ocular albinism is alittle different. This condition is X–linked, meaning that the recessive gene for ocular albinism is located on the X chromosome. X–linked ocular albinism appears just about only in males who inherit the condition from their mothers. Albinism is a recessive inherited defect in melanin metabolism in which pigment is absent from the hair, skin, and eyes (oculocutaneous albinism) or just from the eyes (ocular Albinism). Albinos tend to be children of parents who were first cousins. For a long time, the term "albinism" referred only to people who had white hair, white skin, and blue eyes.

It causes impairments and physical abnormalities. This is a condition where a child is born with an extra copy of their 21st chromosome. According to the National Down Syndrome Society (NDSS), 1 in 700 babies are born with DS. There is not an exact cause of how DS happens but there is an explanation as to what happens. When there is any case of reproduction, genes from both parents are passed to the children.

Children with DS end up with 3 copies or an extra partial copy of chromosome 21 instead of 2 ... Show more content on Helpwriting.net ... Children with DS often grow slowly and as they become an adult they are shorter than normal. Their neck can have excess fat and skin which makes it look shorter than normal. Short, stocky arms and legs along with a wide space between the big toe and second toe is also a physical body symptom. As for face shapes and features they can have slanted eyes, nasal bridge that looks pushed in, small ears that look low on the head, irregularly shaped mouth and tongue. A child's tongue can partly stick out and the teeth can come in late and in a different order than other children. Most children with DS have mild to moderate cognitive disabilities such as impulsive behavior, short attention span and slow learning capabilities. Some health issues that are often symptoms of DS are heart defects, hypothyroidism, eye conditions, hearing and dental problems, respiratory infections and depression. (What is Down Syndrome) Children and adults with DS can face many major health concerns during their life.

Rajasekaran and Avinash Parashar Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee – 247667, India ABSTRACT: The mechanical properties of graphene sheet can be tailored with the help of topological defects. In this research article, the effects of Stone–Thrower–Wales (STW) defects on the mechanical properties of graphene sheet was investigated with the help of molecular dynamics (MD) based simulations. Authors has made an attempt to analyse the stress field developed in and around the vicinity of defect due to bond reorientation and further systematic evaluation has been carried out to study the effect of these stress fields against the applied axial compressive load. The results obtained with the pristine graphene were made to compare with the available open literature and the results were reported to be in good agreement with theoretical and experimental data. It was predicted that graphene with STW defect cannot able to bear compressive strength in zigzag direction, whereas on the other hand it was predicted that graphene sheet containing STW defect can bear higher compressive load in armchair direction, which shows an anisotropic response of STW defects in graphene.

Sometimes mutations and birth defects can occur. Of course, no mother would ever want a child with a birth defect. So how do these birth defects and problems occur? Basically anything a mother does to her body will also have a direct effect on the developing fetus inside. Simply put it, a teratogen is defined as "any agent that can potentially cause a birth defect or negatively alter cognitive and behavioral outcomes." (Santrock, 2013). The effects of teratogens may vary from child to child, but it will always have a dramatic impact on the family in most situations. Birth defects ... Show more content on Helpwriting.net ... Birth defects usually break down into two categories: genetic and non–genetic causes. During conception, half of the mother's and father's chromosomes come together to form the genetic blueprint for the future child. However, sometimes the parents may carry a form of genetic defect that they may not be aware of. Perhaps the defect has been carried down in the family from generation to generation, but just hasn't emerged yet. These defects are established at birth and often cannot be prevented (Selner & Leord, 2012). An example of a genetic birth defect would be Down syndrome. This occurs roughly 1 in 800 births, making it one of the most common chromosomal disorders. Down syndrome is caused by the presence of three copies of the 21st chromosome. One of the biggest causes attributed to Down syndrome has to do with the mother's maternal age.

INTRODUCTION In this project we will be looking at many different kinds of building defects that would be commonly seen in the construction industry. As well as going into detail about the different types of defects using images, cad drawings, and photographs we will also be looking at how to spot the early signs, and how, once a defect has been noticed to fix them.

Because dry rot thrives in damp unventilated areas like floorboards and behind wood panelling most of the time the damage is done before that fungus is discovered. How to spot dry rot, initially the fungus appears as off–white felt–like or cotton–wool like sheets on brickwork and timber and in later stages can develop fungal strands as thick as your finger. Where the fungus is exposed to light it often has a lemon–yellowish colour. Damage is often confined to timber but large flat mushroom–like fruiting bodies can easily grow through finishes such as plaster or paint. These fruiting bodies may be the first visible sign of a problem, and they produce numerous spores which are normally brick–red in colour. Entirely dry–rot decayed timber can be crumbled between your fingers. The fungus leaves deep cracks running across the grain, and there is often evidence of off–white sheets of the fungus on the wood. Also the brick–red spores that it can leave can grow on their own on a new piece of timber if the conditions are right. We can also look at dry rot at the molecular level, structural level, and engineering level. When we look at dry rot at the engineering level we can see the visible effects of the dry rot which would be cotton– wool like fungus. At the structural level once again we would see the cell structure of the wood and how it would be

The Ethics Of The Hippocratic Oath Introduction From the first time that the Hippocratic Oath was used among Greek physicians practice Hippocratic Medicine, it was clear that life, including that of the unborn child (fetus) deserved protection in medicine. The paragraph four of the Oath stated: "I will not give a lethal drug to anyone if I am asked, nor will I advise such a plan, and similarly to give a pessary to cause an abortion" (North, 2002). Centuries later, many nations adopted their abortion laws, at times forcing their physicians to perform abortion as a treatment procedure of a 'disease' called 'pregnancy.' Some states or nations even ventured at specifying the biomedical boundaries to exercise such 'treatment.' One such biomedical boundary is genetic defect. In ...

Arguments for abortion Despite assurances, the risk for fetal defects due to chromosomal aberration remains, physically (tallness, low fertility, infertility, and breast enlargement), mentally (potential manic–depressive problems), and behaviorally (tendency towards behavioral disorders). Purdy (1995) argued that every child should be provided with at least a minimally satisfying life, and genetic defect and its physical, mental and behavioral consequences cannot provide that level of satisfying life. Otherwise, the child will be socially outcast among the "defectives," she will feel unloved, feels resentment for the short end that her birth had given her. The mother also will blame herself for giving birth to her, watching her suffer from such burdensome conditions. Her descendants too will be burdened with her genetic defects and the resultant woes. Purdy (1995) also insisted that, until there are assurances and certainties that the risks are not going to happen, it is the moral duty of the mother to not bring defective babies into the world, and burden the society for their care. Lippman (1991) noted that people do not believe society has an obligation to adjust their lives to the comfort of disabled people. The society has the right for public health, which can only be achieved through a reduction if not elimination to the birth frequency of children with genetic ... Get more on HelpWriting.net ...

Genetic Defects Of Gene Therapy Gene therapy is a process involving the transplant of non–mutant, normal genes into cells, either in place of missing genes, or to essentially replace those genes which are not functioning properly, or not coding for properly functioning proteins, with the purpose of treatment and correction of a number of genetic disorders. This particular type of treatment technique is hoped to, in the future, be able to replace surgery, and a slew of different drugs in the treatment of a variety of diseases in humans caused by genetic defects. This seems to be a promising technique with the potential to redefine the way we approach treatment of many crippling diseases causing human suffering, however, the development of such a technique raises some questions. For one, what exactly is the mechanism of action utilized in such a technique, how is the functional gene translocated to the target cells, and once there, how is the new, functional gene integrated into the target cells in order to effectively "treat" the disorder. Another question is, what clinical diseases and disorders would this treatment be appropriate for, in addition, which disorders have been attempted to be treated with this technique already, and have there been any successes with this treatment technique. Finally, have any ill effects, short or long term, been observed in patients treated with this gene therapy technique? If so, what are they, are these effects irreversible, and have there been any studies into the ... Get more on HelpWriting.net ...

Why Is Genetic Engineering Wrong Sandel challenges the case for perfection in his article by simply stating that genetic engineering is not for him and means nothing, he does not like it but rather thinks that it is the future for fellow Americans and others. It is overall a challenging case of perfection in my opinion because people are messing with nature's course of making life, and people should just let mother nature continue what she's doing and forget about genetic engineering. The number one reason why genetic engineering's bad is because it is not fair. For the simple fact that if someone and their significant other have a child, then they can genetically engineer their child to be the greatest athlete they can be. Skills should be earned, not just given to a child. No matter what kind of raw talent or naturally given gifts, a person still has to do work and apply ... Show more content on Helpwriting.net ... The genetics you receive are all natural, but if you get yours changed it's not fair to you. You shouldn't have anything done or changes made to something that is natural, it can physically affect something in your body and could change your life forever. The harm could be a large portion of your genetics or no harm at all depending on how your body reacts to the engineering. It is unfair and wrong to change something that is naturally selected not just given. Some may argue that it can cure diseases. That is true, but i could definitely lead to something else too. Genetic defects is a side effect of genetic engineering, not all of the time but in some cases. If genetic engineering is attempted while the baby is in the womb it can lead to defects on the kid or even worse a miscarriage. Miscarriage's and birth defects is by far not what the mother and other siblings wants to think about at all. If genetic engineering is causing all of these mishaps then why is it ...

The first leap in this progression has already been established: pre–implantation genetic diagnosis, PGD. Genetic diseases can be halted by utilizing this process, particularly those resulting from single gene defects. This includes cystic fibrosis, sickle cell anemia, and Huntington's disease. Moreover, it has recently been expanded to prevent the development of breast and ovarian cancers by ensuring offspring do not possess the genetic mutation BRCA–1, which increases said cancers risk by eighty and sixty percent respectively.

Babies with Pulmonary Atresia might need surgery or other procedures done soon after birth , so Pulmonary Atresia is considered a critical congenital heart defect. There are two types of Pulmonary Atresia , Pulmonary Atresia with an intact ventricular septum and Pulmonary Atresia with ventricular septal defect. The cause of Pulmonary Atresia is unknown. Some babies have heart defects because changes in their genes or chromosomes. The risk factors of Pulmonary Atresia are a parent who has a congenital heart defect, a mother who has poorly controlled diabetes, drinking or smoking before and after pregnancy,etc. Pulmonary Atresia may be diagnosed during pregnancy or soon after the baby was born. There are many tests to diagnose Pulmonary Atresia such as X–ray, Electrocardiogram, Echocardiogram, etc. if your baby is born with Pulmonary Atresia the symptoms will be noticeable after he/she is born . The symptoms can show within hours or several days after being born.

The Birth Of A Baby With Genetic Defects Science has evolved rapidly, from paternal test, to vitro fertilization (IVF) and testing embryos for genetic defects; and recently talks of designer babies. The first genetically tested embryo was in the US in 2000 . With his birth, came a law in the UK, (which was where this baby was born) prohibiting the creation of more of these babies. This law was created since the British Medical Association, Dr Vivienne Nathanson, said that these babies would feel as "medical products". This law still remains today, but the UK has allowed "the creation of babies with DNA from two women and one man" (Gallagher), to prevent the birth of a baby with "mitochondrial diseases ".

Why is it alright to wish for our child to look a certain way, but when presented with the technology to choice how a child will look like, it is seen as morally wrong? Improvement or enhancements made for health related issues are seen as acceptable but non health related modifications are not acceptable. To understand what a designer baby is, genetics also has to be understood. Generics is the study of heredity, discovered by Gregor Mendel (also known as the father of genetics) and his pea plants experiment. In Mendel's experiment "he described the unit of heredity as a particle that does not change and is passed on to offsprings" (Mandal). This means that a living being gets half of their genes from one parent and the other half from the second parent. These genes are what get modified in designer babies. The term designer babies is the media's name for eugenics. Eugenicists believe that it is in our society's best interest to encourage families with "good genes" to reproduce, and to condemn the "unfit" families. These genetically modified children are considered as the "new eugenics"; "today's version is 'positive': it allows for the creation of more desirable babies" (Tuhus– Dubrow, 40), also the original version deprived people of their rights and liberties. The process used to modify genes is called CRISPR/Cas9. It was discovered in china in 2013; before CRISPR, scientist would ... Get more on HelpWriting.net ...

  • 76. Rubinstein-Taybi Syndrome There are over 5,000 genetic disorders passed down through the generations. These disorders are caused by abnormalities within the chromosomes of an individual. Rubinstein–Taybi syndrome, or RSTS, is a rare genetic disorder that occurs in 1 child out of anywhere between 100,000 to 125,000 children. It was identified by Dr. Hooshang Taybi, a pediatric radiologist, and Dr. Jack Rubinstein, a pediatrics professor, in 1963. RSTS is mainly caused by a deletion within the arm of chromosome 16. However, not all patients have a mutation on the chromosome. According to the Genetic and Rare Diseases Information Center, the disorder can "be caused by a mutation in the CREBBP or EP300 gene... or other genes that have not yet been identified" (GARD 1). CREBBP and EP300 are both codes for different binding ... Show more content on Helpwriting.net ... Most children with the disorder have extreme developmental and intellectual delays. According to an article from the National Organization of Rare Disorders, as children age, they "experience poor growth and exhibit short stature" (NORD 1). The organization also states that most children experience developmental milestones, like crawling and expressive speech, later than normal. Children also experience behavioral issues, including the inability to pay attention, sensitivity to varying sounds, and spontaneous moods. Congenital heart defects, abnormal lungs, spinal deformities, and various malignancies are common among individuals diagnosed with RSTS. Many physical features are also affected. The American Association for Pediatric Ophthalmology and Strabismus describes the ocular symptoms of RSTS as downward "slanting... eyes, widely spaced eyes, strabismus (eye misalignment), ptosis (droopy eyelid),... frequent eye infections...

A Short Note On Non Conformance Records ( Ncr ) Essay The objective of my research is to obtain a general overview of non–conformance records (NCR) that are routed back for defects in the aerospace industry and how it has impacted the integrity of the airplane. Non–Conformances on an aircraft or any other product or service has had an impact on the manufacturing process of a corporation. The documenting of defects has lessened the value of a product or service and often leads to the customer choosing to walk away from a deal, forcing the manufacturer to seek another buyer at a reduced rate. Over time organizations have invested a large amount of time and money to track and manage non–conformances by implementing processes and procedures to assist in reducing or preventing the amount written. Throughout the aerospace industry nonconformances defined is a product or service does not adhere to a process or procedure affecting the quality of service (quality systems, 2015). A Nonconformance record (NCR) documents in detail an identified defect or discrepancy through the use of a centralized database or company internal program so that the information can be reviewed across multiple departments, sites, or locations. This allows the information to be reviewed as a whole, or filtered by user defined criteria. The objective of the NCR is to clearly define the nature of the problem so that corrections are accomplished through reworking the discrepancy, replacing parts or through a form of corrective action (quality systems, 2015).
