HIV can lie dormant in infected cells for years, even decades. Scientists think unlocking the secrets of this viral reservoir may make it possible to cure, not just treat, HIV. Researchers have gained new insight on which immune cells likely do, and do not, harbor this latent virus.
Minority stress — which results from being stigmatized and disadvantaged in society — affects same-sex couples’ stress levels and overall health, research indicates. Authors of a new study state that the health effects of minority stress shared by a couple can be understood as distinct from individual stress, a new framework in the field.
Craigslist’s entry into a market results in a 15.9 percent increase in reported HIV cases, according to research. When mapped at the national level, more than 6,000 HIV cases annually and treatment costs estimated between $62 million and $65.3 million can be linked to the popular website, the authors state.
A strong link between the most aggressive type of breast cancer and a gene that regulates the body’s natural cellular recycling process, called autophagy, has been uncovered by researchers.
Two new fluorescent dyes attracted to cancer cells may help neurosurgeons more accurately localize and completely resect brain tumors, suggests a new study. Removing all visible areas of cancer (gross total resection) significantly improves survival after brain cancer surgery.
More than three-fourths of US neurosurgeons practice some form of defensive medicine—performing additional tests and procedures out of fear of malpractice lawsuits, new research reports.
Ethicists question the impact of health information that is available online, specifically hospital advertisements, and argue that while the Internet offers patients valuable data and tools — including hospital quality ratings and professional treatment guidelines - that may help them when facing decisions about where to seek care or whether to undergo a medical procedure, reliable and unbiased information may be hard to identify among the growing number of medical care advertisements online.
'Bio-molecular interaction analysis, a cornerstone of biomedical research, is traditionally accomplished using equipment that can cost hundreds of thousands of dollars,' said the senior author of a new study. 'Rather than develop a new instrument, we've created a nanoscale tool made from strands of DNA that can detect and report how molecules behave, enabling biological measurements to be made by almost anyone, using only common and inexpensive laboratory reagents.'
Mobile devices are everywhere and children are using them more frequently at young ages. The impact these mobile devices are having on the development and behavior of children is still relatively unknown. Researchers review the many types of interactive media available today and raise important questions regarding their use as educational tools, as well as their potential detrimental role in stunting the development of important tools for self-regulation.
