Smoking and Eye Disease
Smokers appear to have an increased long-term risk and greater
progression of the eye disease age-related macular degeneration,
according to a new article.
Smoking had already been identified as one of the few modifiable
risk factors for age-related macular degeneration (AMD), a leading
cause of vision loss in older Americans, according to background
information in the article. Smoking may contribute to AMD through
several pathways...

Breast Cancer and Tamoxifen
A recent breakthrough in breast cancer
treatment could help save the lives of women who have become
resistant to breast cancer drugs such as tamoxifen. While tamoxifen
has been a huge success in treating breast cancer, for a significant
proportion of sufferers the drugs either fail to work, or after an
initial successful response the patient relapses as the cancer
acquires or possesses resistance to the drug. Researchers have
discovered that reducing the action of a certain protein in the
cancer could prevent or even reverse the resistance to tamoxifen.
Researchers noticed that when breast cancer cells grown in the
laboratory develop resistance to tamoxifen, they show a large
increase in the activity of a protein known as Src -- and by
stopping this activity resistance to tamoxifen can be prevented and
even reversed.

A New Way to Attack HIV – With a Parasite Drug
A drug already used to treat parasitic
infections, and once looked at for cancer, also attacks the human
immunodeficiency virus (HIV) in a new and powerful way, according to
new research.
Past research has established that HIV has "learned" to hide out in
certain human cells where it is safe from the body's counterattack,
cells that come to serve as viral reservoirs. Operating from these
havens, the virus slowly builds its numbers over more than a decade
until it finally becomes capable of dismantling human immune
defenses. In the end stages, this process leaves patients vulnerable
to the opportunistic infections of AIDS. The newly published work
explains for the first time how the virus makes chemical changes
that keep its chosen reservoirs alive long past their normal
lifespan. The new study also provides the first evidence that an
existing ant-parasite drug can reverse this deadly longevity.
These results are profound because, in discovering exactly how HIV
hides in the body, this could help us take away its hiding places.

Retrovirology January 30, 2008.

Viagra and Erectile Dysfunction Videos and Information
The average male has four to
eight spontaneous erections every night while he sleeps. They usually occur
during the REM stage, when dreaming is most common.
In the case of the
penis, there are actually two tasks that it handles:
-
releasing urine from the bladder,
known as urination
-
releasing sperm and seminal fluid
from the prostate gland, known as
ejaculation
-
Viagra helps with the second task: ejaculation.
When things are working properly,
ejaculation is a three-step process:
-
The man becomes sexually aroused.
-
The penis responds by becoming
erect.
-
Stimulation of the penis causes
ejaculation.
That sounds simple enough, but
in many cases, step two does not happen, making step three difficult
or impossible.
-
A man takes a
Viagra
or
Generic Viagra pill.
-
The
Viagra enters his
bloodstream and flows throughout his body.
-
The
Viagra attaches to
the PDE5 enzyme in his penis and disables most of it.
-
When the man becomes sexually
aroused, the brain sends the normal message to the NANC cells in his
penis, which produce nitric oxide as usual.
-
The nitric oxide creates cGMP,
which starts relaxing the arteries in his penis.
-
Since the PDE5 has been disabled,
the cGMP in the penis does not break down. Instead, it builds up and
lets the arteries in the penis fully dilate.
-
His penis inflates with blood, and
the man gets a full erection.

Medicare News - Health-care costs: refusing to pay |
Here's the latest Medicare - Medicaid D Health news we found
today...Health insurers are taking a new tack in a bid to improve patient
safety and reduce health-care costs: refusing to pay -- or let their
patients be billed -- for hospital errors.
Aetna, the country's third-largest insurer by number of members, is
beginning to stipulate in hospital contracts up for renewal that it
will no longer pay nor let patients be billed for 28 different
"never events." Compiled by the National Quality Forum, a coalition
of physicians, employers and policy makers, these mistakes include
leaving an instrument in a patient after surgery, the death of a
mother in a low-risk pregnancy, allowing a patient to develop
bedsores or using contaminated devices. Such errors are so egregious
"there can't be any argument that they should ever happen," says
Troy Brennan, Aetna's chief medical officer.
WellPoint, the largest insurer, is testing the same approach in
Virginia with four errors from the forum's never-events list,
including leaving a sponge or other object in a patient after a
procedure and performing the wrong procedure. It plans to extend the
policy soon to its plans in New England, New York and Georgia.
UnitedHealth Group Inc. and Cigna Corp. say they're exploring
policies similar to Medicare's. The Blue Cross Blue Shield
Association says that its 39 member health plans are looking at
approaches similar to Aetna's or working with hospitals on reducing
errors.

Nature And Nurture To Blame For Depression |
Mental Health
Depression is one of the most common forms of psychopathology.
According to diathesis' stress theories of depression, genetic
liability interacts with negative life experiences to cause
depression, it works on one's mental health.
Studies suggest that the neurotransmitter dopamine may play a role
in the risk for depression. Early negative interpersonal
environments (i.e. rejecting parents) have also been implicated. A
new research team has investigated whether a gene associated with
dopamine interacted with maternal parenting style to predict
episodes of depression...
