Researchers Gather Stem Cells From Discarded Placenta

...nd that a part of the placenta, which is the outer membrane of the amniotic sac have cells that are very similar to embryonic stem cells in their ability to express the two genes that make the embryonic stem cells unique in their capacities. Researchers also said that these amniotic epithelial cells could be ...

Antibiotic from crab blood indentified

... that this protein comes in contact with the outer membrane of the bacteria and create a very strong binding relationship in doing so they make a hole and kill the bacteria in a very short time.// Professor Ho Bow of the National University of Singapore had mentioned that inspite of the fact that the cel...

Mechanical forces drive early heart development

...st at Washington University, has discovered that a membrane that covers the tube may play a major role in causing the rotation to the right.Taber says engineers are just now looking at growth in mature heart. His theory will be valuable in looking at these situations. Growth occurring in the mature heart is e...

Molecule aids fight E. Coli Infections

... is a cell surface receptor that sits on the outer membrane and receives chemical signals. When the scientists deactivated PGRP-LC, the macrophages lost their ability to detect and devour the E. coli microbes -- but not another type of bacteria called Staphylococcus aureus, which also can cause food poisoning...

Natural formula for protection against vision loss

...tes additional free radicals that lead to cell and membrane damage. Science has once again come to our rescue as researchers have found that nutrients and antioxidants can help neutralize dangerous free radicals, and may even provide additional benefits for maintaining healthy vision. These specific nutrient...

Reaction To ADHD Medication May Be Genetic By Nature

...ansporter gene encodes a protein on the nerve cell membrane that helps to clear the neurotransmitter dopamine from the nerve junction. The researchers had first reported an association of this gene with ADHD 10 years ago. In the new study, they had examined the relationship between the gene and patients' med...

A Latest Study Links Fish To Stroke

Loss Of Dystrophin: Common Thread In Cancer And MS Muscle Wasting

...o other proteins associated with dystrophin in the membrane of muscle cells. These proteins form the dystrophin glycoprotein complex. Dystrophin and DGC are also lost in Duchenne muscular dystrophy. The loss of dystrophin and damage to the DGC appear to be key players in the development of both cancer wastin...

Aspirin induces Cancer Cells To Commit Suicide
