Sexually Transmitted Diseases (STD)
... as those of the urethra, cervix, vagina,
anus, eyes and throat.
The contact involved in transmitting gonorrhea is almost always
sexual in nature. It is possible that contaminated fingers can transfer
infection from one region of the body to another, however, this is highly
unlikely because the bacteria dies rapidly when demed the warmth and moisture of
mucous membranes.
Symtoms of infection usually appear within two to ten days after
exposure but might take up to thirty days.
In males, gonorhea usually strikes first at the urethra, the
tube that extends from the bladder to the tip of the penis. A burning sensation
during urination may be experienced due to the ...

Cystic Fibrosis
... cystic fibrosis gene from each parent.
The parents of a child, with cystic fibrosis, each carry one nonworking copy of
the gene and one working copy of the gene. The parents are called cystic
fibrosis carriers, and because they have one working gene they have no symptoms.
Carrier parents have 1:4 chance to have a child who is a noncarrier of cystic
fibrosis, a 1:2 chance to have a child who carries the gene, and a 1:4 chance
with each pregnancy to have an affected child. If you have a son or daughter
with cystic fibrosis, then you have a 1:1 chance of being a carrier. If you have
a brother or sister with CF, you have a 2:3 chance of being a carrier. If you
have ...

Drug Dependence
... drugs even though they take the drug
exactly as directed by the doctor or the label. The human population, unlike a
colony of ants or bees, contains a great variety of genetic variation. Drugs are
tested on at most a few thousand people. When that same drug is taken by
millions, some people may not respond in a predictable way to the drug. A person
who has a so-called idiosyncratic response to a particular sedative, for example,
may become excited rather than relaxed. Others may be hypersensitive, or
extremely sensitive, to certain drugs, suffering reactions that resemble
allergies.
A patient may also acquire a tolerance for a certain drug. This means that

Bipolar Affective Disorder
... of symptoms that can
be broken into manic and depressive episodes. The depressive episodes are
characterized by intense feelings of sadness and despair that can become
feelings of hopelessness and helplessness. Some of the symptoms of a depressive
episode include anhedonia, disturbances in sleep and appetite, psycomoter
retardation, loss of energy, feelings of guilt and worthlessness, guilt,
difficulty thinking, indecision, and recurrent thoughts of death and suicide.
The manic episodes are characterized by elevated or irritable mood, increased
energy, decreased need for sleep, poor judgment and insight, and often reckless
or irresponsible behavior (Holla ...

Respiratory Diseases
... asthma which
is caused by allergies, called extrinsic asthma, usually suffer from hay fever.
Non allergic asthma, which adults usually have, is called intrinsic asthma.
Intrinsic asthma is usually caused by respiratory infections and emotional
upsets. A typical asthma attack begins with coughing, wheezing, and shortness
of breath. Some people have dry coughing as the only symptom. Attacks usually
last only a couple hours. An attack may happen again in hours to even years
after the first attack.
Asthma attacks can be treated and prevented by the use of drugs. Albuterol
or terbutaline, which can bring relief within minutes, is the usual treatment.

The Plague
... from species of squirrels. The last occurrence of
transmissions from rats to people, or people to people in the United States
occurred in 1924 in Los Angeles. In that epidemic there were 32 cases of
pneumonic plague with 31 fatalities. Since then there have been around 16 cases
a year in the United States, most connected with rock squirrels and its common
flea Oropsylla montana.
The most dangerous type of plague is pneumonic. It can be spread through aerosol
droplets released through coughs, sneezes, or through fluid contact. It may also
become a secondary result of a case of untreated bubonic or septicemic plague.
Although not as common as the bubonic strain, ...

Alcoholism

This defect has been noted in many people with a family history of . Some other scientists have been skeptical of these findings, but we now have solid proof that a person is not always an alcoholic by choice. Predestined has been haunting society for years but it is only recently being dealt with.
It is my belief however, that is indeed heredity. The evidence that is provided is simply too substantial to ignore. Family history of shows that throughout the generations th ...

AIDS: Myths And Facts
... that it is spread by
kissing, touching toilet seats, and even that it is spread by mosquitoes.
AIDS has also been labeled the disease of homosexual men. These are all
false beliefs,proven through many scientific studies. Hemophiliacs have
contracted AIDS, after having been giving transfusions of blood which was
contaminated with the HIV virus. Drug addicts have been infected through
the intravenous injection of drugs with “second hand” or dirty needles used
by someone who carried the HIV virus. Prostitutes contract and spread AIDS
through sexual activity with several different partners without knowing
their partners' sexual history. This in turn, leads to t ...

The Future Of Human Evolution
... proposed natural selection or "survival of the fittest" as
the vehicle by which that change occurs. Under Natural Selection, some
individuals in a population have adaptations that allow them to survive and
reproduce
more than other individuals. These adaptations become more common in the
population because of this higher reproductive success. Over time, the
characteristics of the population as a whole can change, sometimes even
resulting in the formation of a new species. Humans have survived for thousands
of years and will most like survive thousands of more. Throughout the history
of the Huminoid species man has evolved from Homo Erectus to what we today call

Joe Smith’s overpowering strength and size seems to have won the game for the Jets and it just so happens that he might have acquired that strength and size through the use of an illegal drug known as anabolic . At the moment everything seems peachy keen, but was it really worth it? Now that I have set the stage, you have probably guessed that my research paper is on anabolic .
