• sudden vision loss;

• ringing in your ears, or sudden hearing loss;

• chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, general ill feeling;

• irregular heartbeat;

• swelling in your hands, ankles, or feet;

• shortness of breath;

• vision changes;

• feeling light-headed, fainting;

• penis erection that is painful or lasts 4 hours or longer; or

• seizure (convulsions).

How our Stem Cells Can Fix our Hear t!

One of the factors affecting in the slow progress of finding a
cure for Stargardt?s is the nature of the gene responsible for this
retinal disease. Some people with the gene never develop the disease,
while others seem to develop it without the gene. Environmental and
unknown factors play a role as well.

In the future, when a patient manifests a genetic defect, doctors
hope to be able to correct it and resolve the problems it causes. Gene
therapy involves inserting a functioning gene into human cells to
correct a genetic error or to introduce a new function to the cells.
The surgeon must transplant genes rather than cells, a strategy which
miniaturizes the process by a million fold. The surgical tools are not
hand-held instruments, but trained viruses. At the 1998 conference of
the Association for Research in Vision and Ophthalmology, a report
presented just such a technique for retinitis pigmentosa (RP), another
retinal degenerative disease. Researchers showed that a virus called
Lenti could carry a new gene into mouse photoreceptors and could
prevent the photoreceptors from degenerating for six months in a mouse
model of recessive RP. That's a long time for a mouse! In another
experiment, an adenovirus was used to deliver a gene designed to
prevent the expression of an abnormal dominant gene for RP. Thus, it
appears that both dominant and recessive forms of RP are amenable to
gene therapy -- at least in mice! Before we can begin human trials of
gene therapy for retinal degenerations, the long term effects of these
viruses, including rejection, must be better understood. Like
transplantation, this approach requires delicate subretinal surgery to
place the virus near the photoreceptors and the RPE.

Genetics food allergy

Allergic reactions to foods are an important medical problem throughout the industrialized world. The occurrence of food allergy appears to be strongly influenced by genetics, but the basis of the genetic predisposition to food allergy has not been differentiated from that for atopy in general.

In addition, genetic susceptibility alone does not explain the prevalence of food allergy satisfactorily, leaving ample room to consider the importance of environmental influences (external, maternal, and gastrointestinal environment) and interactions between the host and the environment.

Several features of food allergy are highlighted in this review:
1) patients with severe food allergies are overwhelmingly atopic, but food allergy occurs only in approximately 10% of patients with other atopic diseases;
2) most patients are clinically reactive to a single food, and although a substantial minority have multiple food allergies, the variety of bonefide food allergies in a given individual is limited;
3) foods contain multiple proteins whereas only a small subset are allergenic;
4) there is likely an important contribution of the environment, becoming manifest in genetically susceptible individuals.

The Truth About Back Pain

There are many different reasons that people have back pain but the most usual reason is poor posture.
If a person constantly sits or stands incorrectly, a sore back is often the outcome.
We were often told by our parents to "sit or stand up straight" as children and they were correct. For a person that has had poor posture their entire lives, eventually their joints damage and start wearing out.
Unfortunately, the back pain caused by this is as severe as a person that had an accident.
There are other causes of back pain and understanding them helps us to avoid or deal with back pain.

If your back pain is persistent then it is time to see a doctor.
The doctor will be able to run tests to find out why you are in pain and the different treatments available to bring you relief from this pain. Usually for less severe back problems, within two weeks of starting treatment, there will be relief from the pain.

Pushing drugs !!

For years, drug companies (pharmaceuticals AKA Big Pharma) have been taking the public for a costly ride and making a killing in the process -- seriously, a lot of people are dying as a result.

In this documentary, find out how Big Pharma's clever politics and marketing schemes are tailored specifically to empty out our bank accounts and force us to sell-off our homes if need be, for drugs that would otherwise cost a few pesos elsewhere in the world.

But it doesn't stop there:

With so much profit potential glistening in their eyes, these companies have little incentive to provide cures.

Rather, they recycle old drugs, modifying them ever so slightly (often resulting in deadly cocktails), for the single purpose of acquiring new patents.

Thus, renewing their monopoly over pricing.

But that's only the beginning - Watch it and see fotr yourself :

Design your own baby ?

New researchers in New York have created what is believed to be the first genetically engineered human embryo, which critics immediately branded as a step toward “designer babies.”

The video shows you the moment of impregnation and how the embryo grows up to be a baby.
