Attention Deficit Disorder
.... could be to blame for the symptoms of Attention Deficit Disorder.
The frontal lobes of the brain are thought to be most responsible for the
regulation of behavior and attention. They receive information from the lower
brain, which regulated arousal and screens incoming messages from within and
outside of the body. The limbic system , a group of related nervous system
structures located in the midbrain and linked to emotions and feelings, also
sends messages to the frontal lobes. Finally, the frontal l .....

AIDS: Aquired Immune Deficiency Syndrome
.... up prick
your finger then mail in the blood sample, in about two or three weeks you call
in and enter your special pin number and they give you your results. I think
this is cool but there has to be some drawbacks like them getting samples messed
up and it getting mixed up in the mail or other stupid things like that, like if
you really don't have the disease but you get someone elses reading who does
have HIV.
Thats about all I know about this horrible disease,so ill move on to
what I found when I reas .....

AIDS And HIV
.... in 1982, epidemiologists at the
Center of Disease Control immediately began tracking the disease back wards in
time as well as forward. They determined that the first cases of AIDS in the
United States probably occurred in 1977.
By early 1982, 15 states, the District of Columbia, and 2 foreign
countries had reports of AIDS cases, however the total remained low: 158 men and
1 woman. Surprising enough more then 90 percent of the men were homosexual or
bisexual. Knowing this more then 70 percent of AIDS vi .....

AIDS And You
.... was 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 c .....

Albinism

and "ty-positive". Persons with ty-negative albinism have no melanin
pigmentation, and more difficulty with vision. Those with ty-positive albinism
have very slight pigmentation, and generally less severe visual difficulties.
Tests were done on the hair roots of individuals with albinism, to tell these
types of albinism apart. However, these hair tests cannot identify types of
albinism, particularly in young children, whose pigment systems are immature.
Therefore hair tests .....

Alzheimer's Disease
.... are also found in the brains of
Alzheimer's 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 f .....

Symptoms of ALS include:
Tripping and falling
Loss of motor control in hands and arms
Difficulty speaking and swallowing or difficulty breathing
Persistent fatigue
Twitching and cramping, sometimes severely
As ALS progresses, all voluntary muscles become useless. The patient
cannot eat, breathe or communicate with others. Total life support may be the
only thing keeping them alive. ALS can lead to total paralysis.
Although there is no cure, .....

Anabolic Steroids
.... of testosterone. There are only four legal uses for steroids treatment
for certain forms of cancer, pituatary dwarfism, and serious hormone
disturbances.
There are two forms of anabolic steroids those taken orally and those
injected. The immediate effects of both are mood swings of many different kinds.
In one study, physicians Ian Wilson, Arthur Prang, Jr., and Patricio Lara found
that four out of five men suffering from dippresion when given a steroid
suffered from dillusions. A research team fr .....

AIDS And Its Causes

developing AIDS. The case distribution in these groups are as follows: (1).
Homosexuals or bisexual males constitute the largest group, about 60% of the
reported cases. This includes 5% who were intravenuous drug as well. (2).
Intravenous drug users with no previous history of homosexuality compose the
next largest group, about 23% of all patients. (3). Hemophiliacs (the people who
have inborn disease characterized by excesssive bleeding and occuring only .....

Antibiotic Resistance In Bacteria
.... not mean the disease has gone away.
Prescribed drugs should be taken until all the medicine is gone so the disease
is completely finished. If it is not, then this will just give the bacteria
some time to find a way to avoid the effects of the drug.
One antibiotic that will always have a long lasting effect in history is
penicillin. This was the first antibiotic ever to be discovered. Alexander
Fleming was the person responsible for the discovery in 1928. In his laboratory,
he noticed that in some of .....

"To See What Factors Affect The Decomposition Of Hydrogen Peroxide By The Enzyme Catalase Which Is Found In The Liver"
.... of hydrogen peroxide are:
1. The temperature of the liver
2. The surface area of the liver
3. The pH of the hydrogen peroxide
4. The concentration of the enzymes
The two variables I am going to look at are temperature and surface area.
Hypothesis: I think that when we test the surface area the bigger the
surface area the quicker the reaction will be. This is because there are more
liver particles that will be exposed to the hydrogen peroxide, therefore the
liver that is ground .....

Birth Defects

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 .....

Body Systems

Now its time for the Nervous System. Its constructed of the brain, the spinal
cord and the nerves (neurons). Its functions are to communicate (fast with short
duration), integration, and to control. The subsequent system is the Endocrine
System (known as ductless too...). This is composed of a lot of things... They
are:pituitary gland - below the brain (master gland), pineal gland - brain (It`s
called the "third eye" by some, because its sensitive to light cycles),

Brain Transplant
.... normally. Many psychological effects
are also possible because the human brain is so complex. Our brain makes us who
we are, and with a different brain we would no longer be unique. A person with
a different brain would seem to be a total stranger and in many ways they would
be. Hopefully these dangerous side effects will convince doctors not to perform
this procedure on humans.
The advancement of technology can be very beneficial to everyone, but I
do not believe that this medical technology o .....

Bubonic Plague

your lymphatic system, such as your neck, inner thigh, groin, and armpits.
This stage is the most painful. Blood vessels break and later the dry blood
turns black underneath your skin.
The treatment for the plague is a vaccine that lasts 6 months. You can use the
preferred vaccine Streptomycin, or gentamicin, teracyclines, or chloramphenicol
are all good substitutes. The treatment must start within 15 h .....
