Role of zinc in development

...s essential for making new body proteins including cell growth and brain development in the unborn baby. It comes from a variety of foods but is most easily absorbed from foods of animal origin such as meat, seafood and poultry. Since iron can interfere with zinc absorption, it would make sense in commu...

Minor mutations in HIV virus

...tations occur they persist. When HIV attacks, the cell alerts the immune system by displaying viral protein fragments on the surface. This is a suicide signal to kill the infected cell. The immune response that is generated depends on the ability to recognise the displayed HIV fragment. The study indic...

Antioxidants also help prevent blood clots and inflammation.// The reason for recommending lots of fresh fruits and vegetables is because they ...

The cocaine danger

When cocaine is introduced, the complement proteins build up on the body's own cells, causing massive tissue damage.Michael Davies of St Georg...

Drug abuse leads to long standing changes in the brain

...subjects. Glucose metabolism is a measure of brain cell activity, and reduced glucose metabolism can be a very sensitive indicator of brain damage and an early indicator of neurodegenerative disease. To their surprise, the researchers saw a marked overall increase in glucose metabolism in the brains of ...

Therapy for stopping the spread of cancer cells

... of Georgia have found that an enzyme that affects cell surface carbohydrates is more highly expressed in cancer cells. The enzyme makes it easier for cells to let go of their neighbours and spread. So there's a potential for blocking this enzyme, known as GnT-V, with drugs and this may form the basis of ...

Animal Fat Enhances Risk Of Stomach

Cholesterol, animal protein and vitamin B12, found primarily in animal products, were also associated with a higher risk of these cancers. Intake of fiber, beta-carotene, folate, vitamin C and vitamin B6 were associated with a lo...
