Antibiotics
Number of Words: 1643 / Number of Pages: 6
... 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 reproduction or to kill the bacteria. Although a large amount of an antibiotic taken at one time might kill the bacteria causing an illness, such a dose usually would make the person suffer from illness caused by the drug. Therefore, antibiotics are given in a series of smaller amounts. This assures ...

... are many different types of drugs. Some drugs are good for you
and some could kill people. Some good drugs are anesthetics, hormones, vaccines,

be poisonous if you take too much.

"To See What Factors Affect The Decomposition Of Hydrogen Peroxide By The Enzyme Catalase Which Is Found In The Liver"
Number of Words: 524 / Number of Pages: 2
... decomposition 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 up will be the quickest reaction.
For temperature it will be the temperature that ...

Factors That Influence Drug Addiction
Number of Words: 855 / Number of Pages: 4
... exist, so it isn’t their existence that effects the addiction, but how readily available to the addict each substance is. The Vietnam Veterans, who used heroin during the war, are an excellent example of how availability strengthens the addiction process. Opiates were very easy to obtain in Vietnam, and as a result ten percent of our soldiers tested positive for heroine use during the war. Upon their return home, Robins et all studied 860 men for their drug use. Their study stated that twenty percent of the men tested (at discharge) were addicted to heroin. Three years later they tested the sam ...

AIDS And Its History

... proportion of the population and is harmless.
It is present in many AIDS patients because most of them have risk factors in their lives such as drug abuse, sexual behavior or other shocks to the system that expose them to many microbes.
AIDS is therefore not infectious, Duesberg argues. He thinks the epidemic is the result of an explosion in the use of "recreational" drugs such as cocaine, which badly damage the immune system. He also claims the epidemic is being fuelled by use of the anti-AIDS drug AZT. It is so toxic, he says, that it brings on AIDS-like symptoms in HIV-positive people. Duesberg ...

An Attempt At Understanding Dreams
Number of Words: 3418 / Number of Pages: 13
... can't hurt me because
I know it's just a dream. I have no idea until today how I'm able to do that,
but it really makes me wonder. I also don't know why I had that dream a few
weeks after the movie and not the same night I watched it, especially that I had
completely forgotten about it until the night of the dream, at least consciously.
Anyway, I decided to use the chance of having to write a paper for
Psychology 201 (especially that I hardly write papers because I'm an Engineering
major), and I almost instantly knew that I was going to explore the world of
dreams and the process of dreaming ...

Iron Absorption From The Whole Diet: Comparison Of The Effect Of Two Different Distributions Of Daily Calcium Intake
Number of Words: 1435 / Number of Pages: 6
... 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 iron binding site on intestinal epithelial cells. It is
believed calcium binds to the protein mobilferrin on the epithelial cells, wh ...

temporal and frontal lobes. Research hypothesis: HD patients have significantly
higher mtDNA deletionlevels than agematched controls in the frontal and temporal
lobes of the cortex. To test the hypothesis, the amount of mtDNA deletion in 22
HD patients brains was examined by serial dilution-polymerase chain reaction
(PCR) and compared the results with mtDNA deletion levels in 25 aged matched
controls. Brain tissues from three cortical regions were taken during an autopsy
