Femoral Hernia
.... the weakened opening.
Diagnosis of a hernia is usually done by a visual examination and by
studying the patients medical history. Sometimes the hernia will be pinched, or
strangulated, resulting in pain and nausea. Other times it may hardly be
noticeable. Treatment usually involves manually manipulating the protruding
portion of the intestine back to the proper place or the surgical repair of the
muscle wall through which the hernia protrudes. Surgical repair of a hernia is
referred to as .....

How Nutrients Get In, And Wastes Out.
.... into smaller units. Occasionally, the simplest form of sugar, a
monosaccharide such as glucose, is present in food. These monosaccharides do
not require digestion.
Proteins are polymers composed of one or more amino acids. When they are
digested, they produce free amino acids and ammonia.
Vitamins are a vital part of our food that are absorbed through the small
intestine. There are two different types of vitamins, water-soluble (All the B
vitamins, and vitamin C) and fat-soluble (vitamins A, D .....

Reproductive Technologies: Does Choice Mean Freedom?
.... to her by medical science or by the men which are directly involved
with them in the decision.
In order to truly understand this issue we must look at it's core,
reproductive technology. This is a vast area to discuss because it ranges from
artificial insemination to abortion to contraception to genetic engineering with
many area in between.
Artificial insemination is the introduction of sperm to an ovum
artificially either inside or outside the female genital tract. Abortion is the
"extermination .....

The Human Genome Project
.... the scientific community and public press through the last half of that
decade. In the United States, the Department of Energy (DOE) initially, and the
National Institutes of Health (NIH) soon after, were the main research agencies
within the US government responsible for developing and planning the project. By
1988, the two agencies were working together, an association that was formalized
by the signing of a Memorandum of Understanding to "coordinate research and
technical activities relate .....

AIDS And YOU
.... spread especially fast by
primarily female prostitutes there. AIDS has already become a crisis of
STAGGERING proportions in parts of Africa. In Zaire, it is estimated that
over twenty percent of the adults currently carry the virus. That figure
is increasing. And what occurred there will, if no cure is found, most
likely occur here among heterosexual folks.
AIDS was first seen as a disease of gay males in this country.
This was a result of the fact that gay males in this culture in the days
before AIDS .....

Huntington's Disease
.... 4. A genetic base that exists in
triplicate, CAG for short, is effected by Huntington's disease. In normal people,
the gene has eleven to thirty-four of these, but, in a victim of Huntington's
disease the gene exists from anywhere between thirty-five to one-hundred or more.
The gene for the disease is dominant, giving children of victims of Huntington's
disease a 50% chance of obtaining the disease.
Several other symptoms of the disease exist other than chorea. High levels of
lactic acid have bee .....

AIDS - What's New ?
.... as the 1917/18 influenza pandemic which killed over 21 million people,
including 50,000 Canadians. Having been lulled into false security by
modern antibiotics and vaccines about our ability to conquer infections,
the Western world was ill prepared to cope with the advent of AIDS in 1981.
(Retro- spective studies now put the first reported U.S. case of AIDS as
far back as 1968.) The arrival of a new and lethal virus caught us off
guard. Research suggests that the agent responsible for AIDS pr .....

AIDS: A U.S.- Made Monster?

antibodies in the immune system." In the course of the illness, the number
of functional T4-cells is reduced greatly so that new anti-bodies cannot
be produced and the defenceless patient remains exposed to a range of
infections that under other circumstances would have been harmless. Most
AIDS patients die from opportunistic infections rather than from the AIDS
virus itself. The initial infection is characterized by diarrhea,
erysipelas and intermittent fever. .....

Impotency: New Therapy
.... Tony Gramazio
As many as two-thirds of the men with impotency because of physical
conditions, vascular disease, stress, trauma, surgery and diabetes, can probably
have an erection again.
A new treatment to help men has been thought to be found. It is less
invasive than most other treatments. According to almost 60 medical centers all
over the United States of America, the new approach has been found.
Transurethral Alprostadil has enabled 64.9% of all men with erectile disfunction
to have an erecti .....

victims. They are found within the cell bodies of nerve cells in the
cerebral cortex, and take on the structure of a paired helix. Other
diseases that have "paired helixes" include Parkinson's disease, Down's
Syndrome, and Dementia Pugilistica. Scientists are not sure how the paired
helixes are related in these very different diseases.
Neuritic Plaques are patches of clumped material lying outside the
bodies of nerve cells in the brain. They are mainly .....

U Of T Professors Devise Better Way To Test Sight In Babies

sensitive than methods previously available, " says Skarf.
At the HSC, VEP's are used in a number of clinical applications: to
determine whether a visual problem is cognitive; to assess whether babies
who don't appear to see well will see better in the future; to determine a
course of treatment for such problems in which one eye turns in or is
weaker than the other eye. The second aspect of the researchers' work
involves the development of a stimulator for stereopsis, or binocular
vision, which is .....

Bronchitis
.... cough, shortness of breath,
sometimes spasm, and frequent infection.
In acute bronchitis, the basic symptoms are a head cold, fever and chills,
running nose, aching muscles and possibly back pains. This is soon
followed by the obvious persistent cough. At first the cough is dry and
racking and eventually becomes phlegmy. The persistent cough is worse at
night than during the day, and when the person breathes in smoke and fumes.
The main symptoms most recognized in chronic bronchitis is, again, a .....

Transplants And Diabetes

control groups received injections of approximately 500-800 islets of
Langerhans from unrelated donors. Of the five treated animals, two
became clinically and biochemically permanently normal. Six months later,
Martin examined the cured rats and found intact, functioning islets
secreting all of their hormones, including insulin. None of the controls
were cured.
Encouraged by their first results, Leibel, Martin, and Zingg decided to
repeat t .....

Iron Absorption From The Whole Diet: Comparison Of The Effect Of Two Different Distributions Of Daily Calcium Intake
.... women(Rossander-Hulten et al and Gleerup et al).
One of the fears of an increased amount of calcium intake is the increased
possibility of anemia in women who are already susceptible to this condition.
The iron inhibition by calcium is a classical example of how the correction of
one nutritional problem can be the cause of another.
The physiological mechanism of this calcium-iron relationship remains a
mystery, however there are two feasible theories. One states that calcium
competes for an i .....

Gut Issues
.... and nerves. Rather,
when eaten they tumble intact through the stomach and small intestine and
end up in the colon where billions of bacterial feed on them - in turn
producing intestinal gas. No wonder, then, that dietary fibre has been
unwelcome in many of history's nicer neighborhoods.
Even 20th century doctors reasoned that since the bulky material provided
not a single nutrient, it would only strain already troubled guts.
Accordingly, they recommended low-fibre diets for patients suffering fro .....
