The Ebola Virus
.... virus. Hemorrhagic fever as defined in Mosby's
Medical, Nursing, and Allied Health Dictionary as, a group of viral aerosol
infections, characterized by fever, chills, headache, malaise, and respiratory
or GI symptoms, followed by capillary hemorrhages, and, in severe infection,
oliguria, kidney failure, hypotension, and, possibly, death. The incubation
period for Ebola Hemorrhagic Fever ranges from 2-21 days (JAMA 273: 1748). The
blood fails to clot and patients may bleed from injections sites and into the
gastrointestinal tract, skin and internal organs (Ebola Info. from the CDC 2).
The Ebola virus has a tropism for liver .....

The Ebola Virus
.... The virons are highly variable in length (polymorphic), some
attaining lengths as long as 14000nm. The Ebola virus consists of a helical
nucleocapsid, which is a protein coat and the nucleic acid it encloses, and a
host cell membrane, which is a lipoprotein unit that surrounds the virus and
derived form the host cell's membrane. The virus is composed of 7 polypeptides,
a nucleoprotein, a glycoprotein, a polymerase and 4 other undesignated proteins.
These proteins are synthesized by mRNA that are transcribed by the RNA of the
virus. The genome consists of a single strand of negative RNA, which is
noninfectious itself. The order .....

Nursing Homes And The Lutheran Home For The Aging
.... and professional work in the Home for the Aging.
The Lutheran Home for the Aging was founded in 1906 by John C. Koch,
with the motivation and desire to promote residential care for his fellow aging
Lutheran constituents. Along with the supportive interests of other Lutherans,
he purchased approximately eight acres of land. A large house on the property
served as the Home's first building and within a year of its founding, it had
reached a capacity of twenty members. Today the same desire and motivation has
increased the residential population to 313 members, age 65 and over. The
founders of the Home did more than provid .....

The Effects Of Altitude On Human Physiology
.... define altitude according to the scale of high (8,000 - 12,000 feet),
very high (12,000 - 18,000 feet), and extremely high (18,000+ feet), (Hubble,
1995). A common misperception of the change in external environment with
increased altitude is that there is decreased oxygen. This is not correct as the
concentration of oxygen at sea level is about 21% and stays relatively unchanged
until over 50,000 feet (Johnson, 1988).
What is really happening is that the atmospheric pressure is decreasing
and subsequently the amount of oxygen available in a single breath of air is
significantly less. At sea level the baro .....

The Fabry Disease

nodes and cornea. Retarded growth, delayed puberty and ocular abnormalities are
also common symptoms. These symptoms are mostly fond in males because they
display full-blown syndrome, while females displays a partial form.
Diagnosis
They firsts take a urine sample, which is the first place where they
would find anything. Then they would take a blood, bone marrow and
ophthalmologic examination. Prenatal diagnosis by way of Amniocentesis or
Chronic Villus Sampling is also available.
Prognosis
People affected by this disorder usually dies by the .....

The Genetics Of Violence
.... civil
rights activists, lawyers, and anxious citizens await the resulting testimony of
the scientists. The social implications of the genetic search for aggressive
tendency is seen by some as a great step forward, by others as a dangerous power
with the ability to give birth to another Holocaust, and by still others as
racist.
At one time, it was believed that one’s character could be determined
from the bumps in one’s skull. Much later, in the 1960’s, as science marched on
in its regular pace, it was theorized that carriers of an extra Y (male)
chromosome were predisposed to criminality. Today, we are faced with the p .....

The Human Brain Vs. The Computer
.... can do it far faster than he can possibly
achieve. Let us go one step further. Say this man can calculate as fast as a
computer, can he, as the computer can, achieve a 100% rate of accuracy in his
calculation? Why do we now go over the human data entry into a computer when a
mistake is noticed instead of checking the computer? It is because computers
now possess the ability to hold no error in its operation, where mankind has not
advanced in this area in any noticeable margin. Why do you think the words
'human error' and 'to err is human' have become so popular in recent years? It
is because the failings of the human race .....

your health card number to the receptionist before continuing. You are then
given a file number, which is your only identity for the time you spend within
the hospital environment. After seeing the doctor you may come out with a few
prescriptions which furthers your nameless ordeal. When you drop nameless

thing they ask is if you know your prescription number. If you cannot remember
it, your actual name is a secondary possibility as a means of identification. .....

Kidneys
.... renal pyramids. The apex of each pyramid, the papilla, extends into the
renal pelvis, through which urine is released from the kidney tissue. The
cortex arches over the bases of the pyramids (cortical arches) and extends down
between each pyramid as the renal columns.
Urine passes through the body in a fairly complex way. The initial site
of urine production in the body is the glomerus. The arterial blood pressure
drives a filtrate of plasma containing salts, glucose, amino acids, and
nitrogenous wastes such as urea and a small amount of ammonia through the
glomerus. Proteins and fats are filtered out of the plasma, t .....

Nature / Nurture Or Both !
.... mystery of “ What is it that makes us who we are?”
“Our genes made us. We animals exist for their preservation and are
nothing more than their throwaway survival machines.” This is what Richard
Darwin states in his book: The Selfish Gene. In his international best seller
book, he argues that we are merely a product of our genes and our main purpose
in life is to serve the genes, become distribution agents and ensure their
proliferation. Before we take any stand to Darwin's statement, let us
familiarize ourselves with what is meant when the term nature is used. Nature
represents what we are born with and cannot control. Our .....

Paranoid Personality Disorders

At times, these individuals may also conjure up flamboyant illusions to confirm
their behavior toward others.
These feelings are also carried out towards family as well. One example
could be as if a person with this personality disorder had a spouse or sexual
partner, this individual constantly thinks that their partner or spouse is
cheating on them. Often, the spouse or partner is barraged with questions
questioning their whereabouts, faithfulness, or intentions.
It is believed that these symptoms first appear usually during childhood
or adolescence. Those believed to be most prone are "loners," .....

The Lymphatic System
.... are many cells in the lymphoid tissue. One type is lymphocytes,
which are reffered to often as T or B cells. Plasma cells are antibody-producing
offspring of B cells. Macrophages are phagocytes that help out with immunity.
Reticular cells are cells that form the lymphoid tissue stroma. Thes cells are
very important parts of the immune system.
The Lymphatic System also contains tissues. The tissue of the Lymphatic
System is reticular connective tissue. It hold the macrophages and changes the
number of lymphocytes. It is an important part of the immune system. The
Lymphoid tissue can be found in the follicles. Lymphoi .....
