Drugs to stop burgeon of HIV

...e researchers showed that a protein created by HIV called Vpu formed ion channels in fatty membranes around cells. Ion channels act as 'gates' for ions to pass in and out of the cell."We had to make a conceptual leap between ion channels and the budding process" said Professor Gage who works in the Division...

Biotechnology on the lead

They're the causative agents of the condition we know as botulism, which normally occurs in humans from contaminated foods."However, this is a toxin that really is one of the most lethal toxins known to man, that could be used a...

Contraceptives have dual effects

...trogen may also help to reduce levels of a hormone called IGF-I that has also been linked to an increased risk of bowel cancer. They focused on the results from 19 international studies that compared bowel cancer rates for women who had taken an oral contraceptive between the mid-1970s and 1980s.Lead resea...

Detection of Cancer

...first stage of the test, C-Test1, uses a technique called mass spectrometry to search for the diagnostic molecule, which seems to be missing when cancer is present.The 'immunostimulator' nature of this diagnostic molecule points to its use as a potential cancer treatment, but Professor Parish cautions that ...

Stem cell transplantation of eye

...une diseases causing damage to the part of the eye called limbus, were successfully treated through this method in the last few months. // Stem cells are found in limbus, which regenerates the ocular surface of the cornea. Conditions such as chemical burns, damages the limbus resulting in limbal stem cell...

Levels Of Blood Proteins May Help Heart Disease Care
