No one is immune to birth defects, yet not everyone is equally susceptible.
Birth defects are not merely a medical problem. They have profound effects on
the social and psychological well being of their family and friends.
In the normal course of fetal development, cells migrate to their
appropriate destination so that organs and limbs form where they should. Usually,
the genes perform flawlessly, but mistakes can and do occur. Some of the most
common birth defects results from the interaction between one or two abnormal
genes out of 100,000 that make up who we are. This is caused by the genes
parents pass on or effected by drugs and alcohol upon the fetus of a new born
Down\'s syndrome, the most common genetic disease formerly known as
mongolism, "occurs one in every six hundred births throughout the world" ( Storm
102). It is caused by chromosomal error, where there is an extra chromosome 21.
Instead of have two chromosomes as does a normal individual, there are three.
These children\'s features include up slanted eyelids, depressed foreheads,
hearing loss, dental problems, poor speech development, heart disease and
intestinal problems where surgery is required. Parents feel very helpless and
guilty in many of these and similar situations, feeling as if they are abnormal.
However most can learn to walk, talk, dress themselves and eat. Special work
programs are available that can help the child reach their education level. Also
these work programs help takes off the many stresses facing parents. They no
longer have to go it alone.
Tay Sachs disease is another selective genetic disorder that destroyed
nerve cells. This causes mental retardation, loss of muscle control and death.
Children who inherit an abnormal gene from both parents will inherit the decease.
The carrier parents have one normal gene and one defective gene. Carriers of
Tay-Sachs disease have no symptoms. " If two carriers have children, each child
has twenty-five percent chance of inheriting the defective gene (both parents)"
(Strom 174). These children are unable to produce an enzyme that breaks down
fats in the brain and nerve cells. The cells become clogged with fat and prevent
the cells from functioning normally. Within three to four years their bodies
Sandra vividly remembers how happy she was to have a baby brother
and what a beautiful, healthy little boy he was at first. Then, at about six
months of age,
her brother began to change. He stopped smiling, crawling and
and he lost his ability to grasp objects or to reach out. Over the
next few years, he gradually became paralyzed and
blind. Finally, he became so affected that he was
completely unaware of anything or anyone around him. Then, just before his
fourth birthday, he died. (Gravelle 56).
" About one in three hundred people carries this disease, but carriers are ten
times more common among mid and eastern European Jews" (Gravelle 56). This
devastating disease has a tremendous emotional effect on the parents. From
day one they watch their beautiful healthy child grow up and live a normal life.
Their child could live a normal life for three to four years without any
symptoms. And then with no warning their normal way of life changes
dramatically as they watch their child suffer a slow traumatizing death. Along
with watching their child, they also have to face their new life. They now have
to sent most of their time and money on the child, but how ? If they both take
off work who will pay for all the doctor bills. If one takes off work who should
it be? Physical breakdowns are a major component facing parents as the deal with
all this added pressure. Their life will consist living around hospitals and
live in nurses which many might get to help cope with the child. Their sex life
changes. Most of the time parents feel dirty or diseased them selves causing
intimacy to stop and from this, parents soon grow farther apart. Their are no
winners in this battle, especially with no cure available.
Sickle cell anemia, a genetic disorder in which malformed red blood cells
interfere with the supply of oxygen to parts of the body. Inadequate oxygen
levels allow the cells to sickle and become a cresent-like shape. As a result,
the cells can no longer flow freely and thus, begin to clog blood vessels.
Inflammation of tissues, pain in limbs, abdomen, lower back and head occurs. The
main organs severely affected are lungs, bones, spleen, kidneys, heart and brain.
It is inherited and acquired only at birth. At
Neural NetworksNeural Networks A neural network also known as an artificial neural network provides a unique computing architecture whose potential has only begun to be tapped. They are used to address problems that are intractable or cumbersome with traditional methods. These new computing architectures are radically different from the computers that are widely used today. ANN\'s are massively parallel systems that rely on dense arrangements of interconnections and surprisingly simple processors (Cr95, Ga93).
All About Ants (almost)All About Ants (almost) Among the many hundreds of thousands of astonishing organisms with which we must share this earth, there is one seemingly ordinary group of specimens which fascinates many people beyond all others. There is nothing too extraordinary in the proportions or appearance of ants, but it is their history and culture that induces a second look. These insects are about as different from us mammals as two organisms can be, yet it appears that of all the known animals their way of l
BiologyBiologyBiology is the science of living systems. It is inherently interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on. All biological specialties, however, are concerned with l
BotanyBotany Botany Choosing a career in botany ensures a person a wide choice of career opportunities, a fair salary, and an exciting life. If you prepare yourself with a good education and a positive attitude, you’ll be well on your way to becoming a successful botanist. Anyone can find enjoyment and fulfillment in a career field as fun and beneficial to others as botany. If you like nature and being outdoors, you might enjoy a career as an ecologist, taxonomist, conservationist, forester, or even a
CloningCloning Cloning, the process of “Manipulating a cell from an animal so that it grows into an exact duplicate of that animal is the forbidden fruit of biology.” (Begley 54). The word “clone”, derived from the Greek word “Klon”, meaning twig or slip, refers to asexual reproduction. Also known as vegetative reproduction. Cloning became known to the public about 30 years ago. This idea of cloning about his time resulted in an experiment of the successful asexual reproduction. This experiment took pl
David Levinson: Seasons' of A Man's LifeDavid Levinson: Seasons\' of A Man\'s Life Introduction Background In May of 1977, Daniel Levinson constructed a model of the season\'s of a mans life. His developmental theory consists of universal stages or phases that extends from the infancy state to the elderly state. Most development theories, such as Freud\'s psychosexual development theory or Piaget\'s cognitive development theory, end in the adolescent stage of life. Levinson\'s stage theory is important because it goes beyond most theo

Then you talk to other new parents, and their babies are doing almost the same things as yours; some a little more, some a little less. Now your baby is a teenager, and you a
Generalized anxiety disorderGeneralized anxiety disorder Young people with an anxiety disorder typically are so afraid, worried, or uneasy that they cannot function normally. Anxiety disorders can be long-lasting and interfere greatly with a child\'s life. If not treated early, anxiety disorders can lead to: missed school days or an inability to finish school; impaired relations with peers; low self-esteem; alcohol or other drug use; problems adjusting to work situations; and anxiety disorder in adulthood. There are a numb

Physiological Adaptations of the Plesiosaur for ‘HPhysiological Adaptations of the Plesiosaur for ‘Holding its Breath’ One hundred and fifty million years ago, large aquatic species of reptile such as the Plesiosaur dominated the ocean, and were pre-eminent predators of the sea. The branch of now extinct Plesiosaurs, or ‘near lizards’, evolved into variant closely related species specialised to take different niches in the food chain. Such species of Plesiosaur include the phenotypically similar Plesiosauroid and Pliosauroid. The physiological

This experience has provided me with insight into the logic behind genetic engineering and experiment design an
PhenylketonuriaPhenylketonuria By Tyler Fortune Biology, 8th hour Phenylketonuria or PKU is one of many genetic disorders. It is a metabolic disease that is caused by not enough of the enzyme phenylalanine hydroxylase. This disease causes high levels of phenylalanine in the blood. The high levels of phynylalanine leads to mental retardation and brain damage. It is most often called PKU, but it is also called: Folling disease, Phenylalaninemia, and Phenylpyruvic Oligophrenia. Phenylketonuria occurs in one out o
Archaeopteryx and Modern BirdsArchaeopteryx and Modern Birds As promised, here are the derived characters with which Gauthier (in his 1986 paper) unites Archaeopteryx with modern birds, outside of all other theropods (with Gauthier\'s original clarifiers in parens) [and with my editorial comments in brackets]: Premaxillae elongate, narrow, and more pointed anteriorly, with longer nasal processes [similar condition in bullatosaurs, and in the nondinosaurian Megalancosaurus, but unique to Archie and later birds in Maniraptora]
SIGMUND FREUDSIGMUND FREUD THE FATHER OF MODERN PSYCHOLOGY Sigmund Freud was born in 1856 and died in 1939. He was a successful psysiologist, medical doctor, and psychologist. He was recognized as one of the most influential and respected thinkers of the twentieth century. He originally worked in close association with Joseph Bruer, and created the theory of psychology. He refined teh concept of the unconscious, of infatile sexuality, of repression, and proposed a tri-partite account of the mind\'s structure
Serial Killing: Is It An Addiction?Serial Killing: Is It An Addiction? The statement that the serial killer is addicted to what he does cannot be properly supported without a discussion of addiction. While the pharmacological examples such as alcoholism and heroin addiction are still the clearest examples of addiction, new models of addictive behavior including exercise addiction, compulsive gambling, and even sexual addiction have gained acceptance. Just as alcoholism was once thought to be a conscious choice, these latter examp
CloningCloning Cloning is the production of a group of genetically identical cells or organisms, all descended from a single individual. The members of a clone have precisely the same characteristics, except where mutation and environmentally caused developmental variation have occurred. The DNA is precisley the same and they are only differentiated by their experiences in which dictate their personality. There are some types of natural cloning that nature displays. Some animals have tremendous powers
CreationismCreationism Traditionally creationism has roots in many religions. There are various forms of creationism in many cultures. One of the most popular tenets in cultures around the world are variation of pair of male and female that parent the entire earth of humans. They indicate generally that there is first cause of humans and animals, usually as a result of an omnipotent being. The Christian version of creationism, that preach God as the sole creator of everything, and that everything that we s
