Dyslexia
.... The left part of the brain
controls the production and comprehension of language and it also deals
with orderly and precise thought. The right part of the brain controls
visual perception, emotion, instincts, and non-verbal responses. Both the
right and left part of the brain must work together to create speech,
writing, and mathematics. Some scientists say that the cause of dyslexia
don’t have anything to do with different brain chemistry, or the genetic
make-up of the person, but rather a result of disturbances in the
environment. Dyslexia is not caused by the loss of sight and hearing,
emotional problems, or metal retar .....

Cigarette Smokers Are Bad For Nonsmokers
.... a smoker you
have a twenty five percent chance of dying from a heart attack. It even
hurts children by giving them bronchitis, asthma and ear aches. There are
about 45 gasses, liquids and metals that cause cancer in the smog.
Smoking costs a lot of money for the people in Canada. It costs the
Canadian economy roughly three hundred and fifty dollars for each Canadian.
Most of these costs come from treating diseases caused by tobacco and from
the loss when workers are too ill and cannot contribute to economic
activity.
The next time a smoker is getting in your way tell him or her to
smoke some where else or if that can’t be don .....

The Effects Of Marijuana Use
.... giving
effects. Mood changes are often accompanied by altered perceptions of time
and space and of one's bodily dimensions. The thinking processes become
disrupted by fragmentary ideas and memories. Many users report increased
appetite, confusion, acute panic reactions, anxiety attacks, fear, a sense
of helplessness and loss of self control. Chronic weed users are said to
develop "a motivational syndrome" decreased motivation and preoccupation
with drug taking. The relationship of this syndrome to weed has not been
established. Marijuana intoxication in some cases also impairs reading,
comprehension, memory, speech, prob .....

The Real Side Of Tobacco, Drugs, And Alcohol
.... eight times more likely to use marijuana,
and 22 times more likely to use cocaine.
Among the many drugs used by people, marijuana is the most commonly
used. People who use this drug become less motivated and less social.
Also, their emotions become less apparent. It can also cause problems with
having children. If enough of this drug is taken over a long period of
time, then it can cause psychotic episodes. The more the drug is used,
the more of a tolerance is built up, thus meaning the more marijuana you
need to get "high". Marijuana has not been proven to be physically
addictive, but it is mentally addictive. People w .....

Biofeedback
.... state from feedback from the sensors. Margolin and Kubic (1944)
conducted an early example of this kind of feedback. They used a subject's
amplified respiration and heart beat to induce a hypnotic induction. Even
though the subjects were not told to adjust these physiological functions,
the feedback of their biological system was used to alter their conscious
and emotional state (O'Hair). The principles of operant conditioning have
often been used by people to explain biofeedback. In operant conditioning,
any activity that approximates the desired behavior or response is
reinforced or rewarded. By using these types of conditioni .....

Two Sides Of The Brain
.... Most people, if they thought about it, would identify more with
their left brain. In fact, many of us think we are our left brains. All
of that non-stop verbalization that goes on in our heads is the dominant
left brain talking to itself. Our culture- particularly our school system
with its emphasis on the three Rs (decidedly left-brain territory) -
effectively represses the intuitive and artistic right brain. If you don't
believe it, see how far you get at the office with the right brain activity
of daydreaming.
As you read, your left-side is sensibly making connections and
analysing the meaning of the words, the .....

The Human Immunodeficiency Virus And Mutations
.... DNA. For example,
within the core of HIV is a double molecule of ribonucleic acid, RNA.
When the virus invades a cell, this genetic material is replicated in the
form of DNA . But, in order to do so, HIV must first be able to produce a
particular enzyme that can construct a DNA molecule using an RNA template.
This enzyme, called RNA-directed DNA polymerase, is also referred to as
reverse transcriptase because it reverses the normal cellular process of
transcription. The DNA molecules produced by reverse transcription are
then inserted into the genetic material of the host cell, where they are
co-replicated with the host's chr .....

Prolonged Preservation Of The Heart Prior To Transplantation
.... goes, he will probably not receive a donor heart
before his own expires.
Currently, when a heart is being prepared for transplantation, it
is simply submerged in an isotonic saline ice bath in an attempt to stop
all metabolic activity of that heart. This cold submersion technique is
adequate for only four hours. However, if the heart is perfused with the
proper media, it can remain viable for up to 24 hours. The technique of
perfusion is based on intrinsically simple principles. What occurs is a
physician carefully excises the heart from the donor. He then accurately
trims the vessels of the heart so they can be easi .....

Teen Suicide
.... child about their concerns and seek professional help when the
concerns persist.
Teen suicide leaves behind an unceasing wake of questions. Parents,
friends, and classmates all ask in endless echo-WHY? Everyone tries to
make sense of it. But no sense can be made. All questions. No answers.
Just the cold, haunting specter of senseless death. Psychological studies
have discovered a number of links to teen suicide. It comes as no surprise
that depression and hopelessness typically top the list. Alcoholism and
drug abuse are prevalent among kids who attempt suicide. A history of
sexual abuse can also contribute to a teen's choice to .....

The Argument Against Female Circumcision
.... genitals and to prevent struggling. Then the daya
would proceed to cut of the clitoris of the girl with a sharp razor. One
of the women El Saadawi interviewed explained "the daya sat between these
two women, holding a sharp razor in her hand which she used to cut off the
clitoris." (Nawal El Saadawi 170)
Although El Saadawi claims there are no advantages to this
operation, many people tend to disagree. One claim made by people in
favor of female circumcision is that by minimizing sexual desire, a girl
is more likely to stay a virgin. Studies show that by removing the
clitoris, sexual desire is drastically decreased. "A marrie .....

Bulimia
.... a person in a car who is ordering
large quantities of food. After eating the person vomits or uses laxatives
to get rid of the food. When they see the apple peel or corn leave the
body they know that the food they have eaten has been totally eliminated
because the apple or corn is easily recognized and does not digest. A
typical binge can be between 1,00 and 11,000 calories. The food is consumed
at a rate of approximately 166 calories per min. (See Chart) The food is
not chewed well. They take a bite and swallow as fast as they can. This
gives them a feeling of euphoria or a "high". Obtaining this amount of
food can be ve .....

Alcoholism: Is It Hereditary?
.... for prevention and treatment policies. A tremendous amount of
attention and research has recently been concentrated on the inheritance
of alcoholism and on the possibility of accounting genetically for drunken
behavior. The major purpose for this research was the adoption studies
conducted in Scandinavia in the 1970’s which found reliable genetic, but
not adoptive transmission of alcoholism. This contemporary research
focuses on the offspring of alcoholics and on the biochemical or
neurological abnormalities they inherit that may lead to pathological
drinking. Or, alternatively, investigations may focus on .....
