Antibiotic Resistance In Bacteria
.... 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 his bacteria colonies, that he was growing, were some
clear spots. He realized that something had killed the bacteria in these clear
spots, which ended up to be a fungus growth. He then discovered that inside
this mold was a substance that killed bacteria. It was the antibiotic,
penicillin.
Penicillin became the most power .....

"To See What Factors Affect The Decomposition Of Hydrogen Peroxide By The Enzyme Catalase Which Is Found In The Liver"
.... 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 is forty degrees Celsius
because the enzymes in the liver will not exist after the temperature goes over
forty degrees Celsius. I know this due to previous experiments that I have
carried out. I think the rate of decomposition will double ever .....

Birth Defects
.... 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
longer have to go it alone.
Tay Sachs disease is another selective genetic disorder that destroyed
nerve cells. This causes mental retardation, loss of muscle control and death.
Children who inherit an abnormal gene from both parents will inherit the decease.
The carrier parents have one normal gene and one defective gen .....

Body Systems
.... 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),
hypothalamus - also in the brain (it works with the pituitary), the thyrodic -
neck (controls the metabolism), adrenal - kidneys (responsible for the
adrenaline), pancreas - near stomach (produces insulin), ovaries - on females
and testes - on males (it produces estrogen and ova - testosterone and sperm,
respectively). Their functions a .....

Brain Transplant

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 of brain transplants will help
anyone. We were all born with one brain and through childhood to adolescence
our mind developed into who we are. No one should steal our identity from us,
even if we are seriously injured, and change it to a completely new one. Also
for the people who have died with healthy brains, that was the .....

Bubonic Plague
.... 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 hours of the first
symptom of death is inevitable.
Some special characteristics of this disease are you can be any age to contract
it, it is most common is unsanitary condition, or where there are an abundance
of rodents and if untreated death will occur within 3 days. The most amazing
fact about this disease is that it has .....

Cancer
.... benign tissue does not metastasize, or begin to grow in
other sites, like malignant tumors do. Cancer always refers to metastasized
tumors but the term tumor is not always necessarily cancer. A tumor is any
living tissue that is distinguishable as abnormal living tissue. After a
cancer forms, it can also change from a benign to a malignant state, therefore
making the cell grow at a more rapid rate. The development of the cell starts
when it forms notable abnormalities in chromosomes and then multiplies
exceedingly. Then metastasis usually occurs and generally causes the death of
the host. There are many different cancers which f .....

Can Genetics Cause Crime?
.... of
"Seeking the Criminal Element," in Scientific American,(1995 March) pp 100-107,
is that a very small number of criminals are responsible for the majority of the
violent crime.
Sullivan who is now the president of the Morehouse School of Medicine in
Atlanta wanted to try and address the violence as a public health issue. In an
interview after he left office in 1993, Dr. Sullivan explains that his rational
for this was that the higher increases in violent crimes and specifically
homicide in the young male population in large cities. Which was higher than
any other social group in America at this time.
Dr. Sullivan then be .....

The Circulatory System
.... then it is brought back to the heart by the four pulmonary veins, which
enter the left auricle. When this chamber contracts, blood is forced into the
left ventricle and then by ventricular contraction into the aorta. The bicuspid,
or mitral, valve prevents the blood from flowing back into the auricle, and the
semilunar valves at the beginning of the aorta stop it from flowing back into
the ventricle. Similar valves are present in the pulmonary artery.
The aorta divides into a number of main branches, which in turn divide
into smaller ones until the entire body is supplied by an elaborately branching
series of blood vessels. Th .....

Acupuncture
.... points are then stimulated by various forms of needle stimulation.
Acupuncture is an incredibly effective form of medicine; This essay will
present details explaining some of the uses of acupuncture.
Acupuncture; the insertion of needles into the body through specific
spots, over neurorecepters. These needles are then stimulated by either:
rotation, heat, or by a weak electrical current. Acupuncture is a medical
technique used primarily as a relief of pain, but is known to cure disease, as
well as improve general health. "The theory suggest that acupuncture blocks the
transmission of pain impulses from parts of the body .....

Clinical Chemistry Tests In Medicine
.... is another indicator of kidney function. Creatinine is a
waste product derived from creatine. It is freely filtered by the glomerulus
and blood levels are useful for estimating glomerular filtration rate. Muscle
tissue contains phosphocreatinine which is converted to creatinine by a
nonenzymatic process. This spontaneous degradation occurs at a rather
consistent rate (Merck, 1991).
Causes of increases of both BUN and creatinine can be divided into three
major categories: prerenal, renal, and postrenal. Prerenal causes include
heart disease, hypoadrenocorticism and shock. Postrenal causes include urethral
obs .....

Current Status Of Malaria Vaccinology
.... for the hepatic cells of the liver where
they multiply by asexual fission to produce merozoites. These merozoites can now
travel one of two paths. They can go to infect more hepatic liver cells or they
can attach to and penetrate erytherocytes. When inside the erythrocytes the
plasmodium enlarges into uninucleated cells called trophozites The nucleus of
this newly formed cell then divides asexually to produce a schizont, which has
6-24 nuclei.
Now the multinucleated schizont then divides to produce mononucleated merozoites
. Eventually the erythrocytes reaches lysis and as result the merozoites enter
the bloodstream and infe .....
