The Bubonic Plague
.... they
all played a role. There is evidence to support that plague was caught from
baggage and bales of clothes and cloth, as in Eyam in Derbyshire in 1665.
There is also existing evidence that human transmission is solely
responsible. The spread of the plague across the country was far too rapid
to be accounted for by wild rodents in the countryside, and it is human
transport which explains its movement along the major trade routes, usually
by ship(British port to port), or on main roads and navigable rivers.
Nevertheless, it is reasonable to assume that rodent transmission played a
part in local village to village contamination .....

Spinal Fluid May Help Alzheimer's Diagnosis

Alzheimer's was detectable in some way.
Yes, I would recommend this article to another student. I feel
that a number of people should be known to the subject of Alzheimer's by
itself. Because a number of families have a member in it that may have
Alzheimer's and this article would help them understand the disease a
little bit better.

The Human Heart
.... is
the middle layer. The inner layer, or endocardium, that lines the inside of
the heart muscle consists of a thin layer of endothelial tissue overlying a
thin layer of vascularized connective tissue. The outside of the heart, the
epicardium, is in intimate contact with the pericardium; this serous
membrane is a closed sac covering the heart muscles outside wall. Within
the sac, a small amount of fluid reduces the friction between the two
layers of tissue. In addition to, muscular and connective tissue, the heart
muscle contains varying amounts of fatty tissue, especially on the outside.
Both anatomically and functionally, the h .....

For women trying to become pregnant, smoking may impair fertility.
For pregnant women, smoking increases the risk of ectopic (tubal) pregnancy,
miscarriage, and stillbirth. (1)
Babies born to women who smoke during pregnancy may suffer from
growth retardation in the womb and typically lower in birth weight than are

Depression And Its Causes
.... social statuses, homosexuality,
and mental retardation could also cause a child or young adult to become
depressed. Doctors say that the depression symptoms for kids are the same
as in adults, except that children suffer more from physical symptoms such
as hallucinations, agitation, and phobias. This depression in childhood
and adolescence can lead to poor school performance, alcohol and drug abuse,
promiscuity, teenage pregnancy, other pyschiatric illnesses, and suicide.
The suicide rates have doubled since 1988, and 1/3 of them are the result
of depressed adolescents.
There are several types of depression, but all types .....

Interpretation Of Dreams Revisited
If we are to understand Freud's view of the dream, we need to consider
his concept of the dreamer's brain. We know today that the nervous system
contains two types of nerve cells (excitatory and inhibitory). Both types
discharge and transmit electrochemical impulses to other neurons. Both do
this spontaneously, without any kind of outside stimuli, as well as when
they themselves receive excitatory impulses from other cells. However, one
critical difference between these two types of neurons is that one type,

processing when needed. This kind of memory has some kind of limited storage
space, which is used when processing information, however the trade-off is that
is slower than Short term memory.
Long Term : Long term memory is the dumping ground for all of the used
information. Here is where the Medium term memory puts, and takes it's
information to and from. It has a large amount of space, but is relatively slow
in comparison with the other kinds of memory, and the way that the memory is
stored is dubious as we are all knows to forget things.
There is quite a good .....

On Ockham's Razor And Gulf Ills

Infectious diseases
Oil-well fires

Pyridostigmine bromide as an antidote to poison gas

Several of these putative causes, such as oil-well fires, can be eliminated
if, as Katherine Leisure finds, some servicemen and women who suffer from
the syndrome were long gone from the Gulf before combat started and Iraq
fired the wells.
Per Ockham's Razor, we think infectious diseases is the simplest hypothesis
at the moment, and leishmaniasis the best candidate among them. If there is

Sturge Weber Syndrome
.... patients with the Sturge Weber Syndrome are usually only
impaired on one side of their physique. They experience slow reflexes or
the inability to even move a limb opposite the port-wine stain.
Retardation is by far the worst of all effects. Most do not endure
retardation, but in some causes the extent has been ghastly. On an average
40% of the underprivileged suffering from the Sturge Weber Syndrome has
some degree of retardation. Glaucoma effects only 30% of the patient, but
usually is restricted to on eye and, occurs in later years of their lives.
A port-wine stain is another effect that is on the side of the face even

Sports Therapy
.... sports psychologists call it, mental toughness. Sports psychologists
James Loehr, calls "mental toughness," the ability to handle and even enjoy
the psychological pressure of a competitive situation. (Harry Hurt, 1996,
p.12) Many of today's best athletes seek help from sports psychologists, in
order to help them with their overall game.
Negative thoughts and psychological pressure from competitive
moments; create many distractions for athletes who do not focus mental
pictures in their minds. A vivid picture, is one that allows individuals
to see stress and negative thoughts as a challenge, rather than a threat.

The Battle Against AIDS

produce more HIV. This infection kills the CD4 cell and spreads AIDS
viruses to other CD4 cells, where the process is repeated.
HIV can be present in the body for 2 to 12 or more years without
producing any outward sign of illness. An infected person can transmit the
virus to another person whether or not symptoms are present. Infection
with HIV appears to be lifelong in all who become infected. People
infected with HIV eventually develop symptoms that also may be caused by
other, less serious conditions. With HIV infection, however, these
symptoms are prolonged .....

Understanding Panic Disorders
.... disorder, brief episodes of intense fear are
accompanied by multiple physical symptoms (such as heart palpitations and
dizziness) that occur repeatedly and unexpectedly in the absence of any
external threat. These “panic attacks,” which are the hallmark of panic
disorder, are believed to occur when the brain's normal mechanism for
reacting to a threat—the so-called “fight or flight” response—becomes
inappropriately aroused. Most people with panic disorder also feel anxious
about the possibility of having another panic attack and avoid situations
in which they believe these attacks are likely to occur. Anxiety about
another at .....
