Scientists used a novel live-cell fluorescent imaging system that allowed them for the first time to identify individual viral particles associated with HIV infection.
A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue -- such as an organ or a small animal; technology that could have applications in medical diagnosis, guided surgery, or pre-clinical drug testing.
Study of kidney cancer incidence in California over 25 years is the first report to demonstrate that the rising rate of kidney cancer seen in the US over the past two decades may have ended.
Harvard Medical School researchers have identified the mechanism behind red blood cell specialization and revealed that it is controlled by an enzyme called UBE2O. This finding could spark the development of new treatments for blood disorders and cancers.
Researchers at UC San Diego Moores Cancer Center, with colleagues from Memorial Sloan Kettering Cancer Center and Fox Chase Cancer Center, have determined that a specific region of the small bowel, called the duodenal-jejunal flexure or DJF, shows a high frequency of gastrointestinal stromal tumors (GISTs) with mutations of the NF1 gene.
Researchers from the Icahn School of Medicine at Mount Sinai have identified a brain mechanism in siblings of bipolar patients that makes them resilient to bipolar disorder. The results suggest that the brain is able to adapt to the biological risk for bipolar disorder and open new avenues in pursuing further research to enhance resilience in those at risk and currently affected.
For the first time, scientists have shown that a female fruit fly's pheromone signals can actually tell males how much energy her body has invested in egg production versus in storing away energy for her own survival. And it's a signal that she can't change in order to make herself more attractive.
Cedars-Sinai neuroscience investigators have found that Alzheimer's disease affects the retina -- the back of the eye -- similarly to the way it affects the brain. The study also revealed that an investigational, noninvasive eye scan could detect the key signs of Alzheimer's disease years before patients experience symptoms.
Adding another reason for doctors to avoid the overuse of antibiotics, new research shows that a reduction in the variety of microbes in the gut interferes with the immune system's ability to fight off disease.
A drug-like molecule developed by Duke Health researchers appears to intercede in an inflammatory response that is at the center of a variety of diseases, including some cancers, rheumatoid arthritis and Crohn's disease.
