Laboratory Testing Can Identify Risk of Pre-Term Labor and Delivery

...(fFN).A glycoprotein that is secreted by the fetal membrane and found in the choriodecidual junction, fFN is responsible for cellular adhesions. The level of fFN in the woman's cervicovaginal secretions is highly associated with pre-term labor and pre-term delivery. The fFN immunoassay detects concentrations ...

Feeding channel created by malaria parasite - a new target for malaria treatments

Drugs to stop burgeon of HIV

...opies of themselves, the virus goes to the surface membrane and wraps it around themselves before 'popping' off.// In 1996 the 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."...

Biomarker for prostate cancer may be separated for treatment

... The researchers had placed the prostate-specific membrane antigen (PSMA) at a new location for the immunotherapy that is carried by the blood, to reach the biomarker. This had been done by a chemotherapy agent, which destroys the microtubules. Cancer of the prostate glands is one of the deadlier cancers th...

"If the acrosome reaction occurs before a sperm reaches an egg, then fertilisation is unable to take place because the sperm has lost special docking molecules that allow it to bind to the egg," she said. The findings...
