Antibiotics
.... once life-threatening.
How Antibiotics Work ?
Antibiotics can be bacteriostatic (bacteria stopped from multiplying)
or bactericidal (bacteria killed). To perform either of these functions,
antibiotics must be brought into contact with the bacteria.
It is believed that antibiotics interfere with the surface of bacteria
cells, causing a change in their ability to reproduce. Testing the action
of an antibiotic in the laboratory shows how much exposure to the drug is
necessary to halt reproductio .....

The Human Brain
.... to solve
problems. These processes improved as more and more people supplied their
experiences to the common pool of knowledge. Such co-operation created the
modern man with his superb ability to think.
Many sciences were born. Some of them centered around humans. They
included, among many others, psychology and neurology. While psychology
deals with the mind and human behavior, neurology is the study of the
nervous system.
The nervous system of the human being consists of several parts. .....

The Human Brain
.... into many different parts called organs. All
of the parts are controlled by an organ called the brain, which is located
in the head. The brain weighs about 2.75 pounds, and has a whitish-pink
appearance. The brain is made up of many cells, and is the control centre
of the body. The brain flashes messages out to all the other parts of the
body. The messages travel in very fine threads called nerves. The nerves
and the brain make up a system somewhat like telephone poles carrying wires
across the city .....

Cancer In American
.... cancer, a disease that mainly strikes
the elderly. In the United States in the mid-1980s, more than one-fifth of
all deaths were caused by cancer; only the cardiovascular diseases
accounted for a higher percentage. In 1990 the American Cancer Society
predicted that about 30 percent of Americans will eventually develop some
form of the disease. In the United States skin cancer is the most
prevalent cancer in both men and women. Lung cancer, however, causes the
most deaths in both men and women. LEUKEM .....

Cholera
.... Peru, already afflicted by economic ills and
feastering guerilla insurgency, is now plagued by an epidemic of Cholera.
As of February 25, 1991, the disease had claimed 90 lives and infected at
least 14,000 people. It is the first major outbreak of Cholera in the
western hemisphere since early in this century. In Peru, local authorities
have moved quickly to stem the epidemic, which is spread by poor hygiene
and contaminated water, raw food, and fish. To avoid spreading, health
officials in Ecuador, .....

Insulin-Dependent Diabetes
.... produced by the pancreas gland
(located behind the stomach). In the person with diabetes, there is
a malfunction in the production of insulin. There are two main types
of diabetes: Type I or Insulin-Dependent and Type II or Noninsulin-
Dependent.
The insulin-dependent type of diabetes generally has onset during
childhood or adolescence, though it can occur at any age. Because
the pancreas supplies little or no insulin in this disease, daily
injections of the hormone a .....

Multiple Personalities: Do They Really Exist?
.... and time loss in the primary personality, who
often does not have access to the memories of the other personalities. A
common misconception among the general public is the confusion of MPD with
the disease of schizophrenia. Schizophrenics do NOT have distinct
personalities, rather, they have hallucinations of voices outside their
heads. Schizophrenia is caused by brain malfunctions and can be treated
with drugs, whereas suffers of MPD cannot because MPD is an almost purely
psychological disorder. MPD .....

people.
Greed and Profiteering: Some drug companies make over 10,000% profit on
the drugs they manufacture. In 1991, the median income of doctors was
$139,000 for general practitioners and $512,000 for specialists.
Unneeded Surgery and Tests: Possibly 15 to 35% of certain types of
operations and tests are unneeded. Malpractice Suits and "Defensive"
Medicine: Doctors pay high premiums on malpractice insurance which causes
them to charge more. The reason that thes .....

Lyme Disease
.... spot (papule). The skin lesion usually
appears on an extremity or on the trunk, especially the thigh, buttock or
the under arm. This spot expands, often with central clearing, to a
diameter as large as 50 cm (c. 12 in.). Approximately 25% of patients with
Lyme disease report having been bitten at that site by a tiny tick 3 to 32
days before onset of ECM. The lesion may be warm to touch. Soon after
onset nearly half the patients develop multiple smaller lesions without
hardened centers. ECM generall .....

Cigarette Smoking

Also business may decrease if they do not allow smokers the right to smoke,
ecspecially bars and restaurants. The work place is another problem for
smokers, now they have to go outside even in the winter to have a cigarette,
even though they used to be able to smoke inside.A strong supporter on
smokers rights is Democratic Assemblyman Dick Floyd, who wanted to vote for
a controversial smokers right bill. He feels it is not a smoking bill, it
merely protects the people who use legal .....

Neural Networks
.... applied to translate images into keywords or even
translate financial data into financial predictions (Wo96).
Neural networks utilize a parallel processing structure that has large
numbers of processors and many interconnections between them. These processors
are much simpler than typical central processing units (He90). In a neural
network, each processor is linked to many of its neighbors so that there are
many more interconnections than processors. The power of the neural network
lies in the treme .....

AIDS/HIV
.... fever, and diarrhea. It is
usually characterized by severe weight loss and fatigue. The AIDS disease
makes the less serious conditions harder for your body to control or get rid of
because of the loss of many of the white blood cells in your body. The most
common causes of death for the people with AIDS are pneumonia and Kaposi's
sarcoma. Kaposi's sarcoma which shows up as purple lesions on the skin and
tumors known as B-cell lymphomas have affected 70% of the infected people.
AIDS is transmi .....

Malpractice Or Poor Judgement?
.... These costs will only be passed along to the
patients in the long run, and the condition is only going to worsen. Take for
example the United States, where surgeons annually pay an average of $75,000 on
insurance premiums. On top of these premiums, doctors who practice very
defensively add as much as $21 billion US to the health care bill every year.
Twenty percent of the tests prescribed by doctors were not necessary, but they
are the result of defensive practising by doctors who do not want to be he .....

Alcoholism
.... merely excessive or irresponsible drinking, has been
variously thought of as a symptom of psychological or social stress or as a
learned, maladaptive coping behavior. More recently, and probably more
accurately, it has come to be viewed as a complex disease entity in its own
right. Alcoholism usually develops over a period of years. Early and subtle
symptoms include placing excessive importance on the availability of alcohol.
Ensuring this availability strongly influences the person's choice of associate .....

variations among users. Some users may become intoxicated at a much lower Blood
Alcohol Concentration (BAC) level that I am about to show you. Along with
drinking their are different levels to it:
0.02-0.03 BAC: No loss of coorination,slight euphoria and loss of shyness.
Depressant effects are not apparent. 0.04-0.06 BAC: Feeling of well-being,
relaxation, lower inhibitions, sensation of warmth. Some minor impairment of
reasoning and memory, lowering of caution. 0 .....
