Addressing perceived stigma about taking HIV medication can help women at risk

Stigma is an important contributor to the continued HIV epidemic in the United States. While pre-exposure prophylaxis (PrEP) is a medication that can be taken to prevent HIV infection, previous research has shown that a barrier preventing gay, bisexual and other men who have sex with men from using PrEP is fear that partners, family members or community members would believe that those who use PrEP are HIV infected.

Single vaping episode of cannabis could yield positive results in urine drug tests

In a study of six adults, Johns Hopkins Medicine researchers report evidence that a single vaping episode of cannabis that is similar in chemical composition to that found in legal hemp products could possibly result in positive results on urine drug screening tests commonly used by many employers and criminal justice or school systems.

Protein may help predict, prevent and treat brain metastases

A protein that breast, lung and other cancers use to promote their spread--or metastasis--to the brain, has been identified by a team led by Weill Cornell Medicine and New York-Presbyterian investigators. The protein, CEMIP, will now be a focus of efforts to predict, prevent and treat brain metastases, which are a frequent cause of cancer deaths.

Properties of spider silk proteins could be selectively modified to synthesize novel biomaterials

Spider silk consists of fiber-forming proteins, stored by the spider in a specialized gland. When the spider needs silk, for instance to build a web, it extrudes the silk proteins through a long duct in which they are exposed to specific mechanical and chemical influences and assembled to form silk.

Risky strategy allows malaria parasite to quickly respond to unpredictable changes

The parasite that causes malaria expresses genes that code for the proteins it will need in later life stages, using two separate schemes to prevent these proteins from actually being made until they are needed, according to new research.

Study shows how measles virus causes immune amnesia

Over the last decade, evidence has mounted that the measles vaccine protects in not one but two ways: Not only does it prevent the well-known acute illness with spots and fever that frequently sends children to the hospital, but it also appears to protect from other infections over the long term.

Researchers identify new kidney cancer subtypes and clues to better diagnosis, treatment

In what is believed to be the most comprehensive molecular characterization to date of the most common - and often treatment-resistant - form of kidney cancer, researchers at Johns Hopkins' departments of pathology and oncology, Johns Hopkins Kimmel Cancer Center, and the Johns Hopkins University School of Medicine report evidence for at least three distinct subtypes of clear cell renal cell carcinoma (ccRCC), along with new revelations about the proteins that define them.
