Organ transplant rejection is a major problem in transplantation medicine. Suppressing the immune system to prevent organ rejection, however, opens the door to life-threatening infections. Researchers at the University of Basel's Biozentrum have now discovered a molecular approach preventing rejection of the transplanted graft while simultaneously maintaining the ability to fight against infections.

A new study in Conservation Physiology shows that over time, bears get used to drones. Previous work indicated that animals behave fearfully or show a stress response near drone flights. Using heart monitors to gauge stress, however, researchers here found that bears habituated to drones over a 3 to 4-week period and remained habituated.

In a randomized clinical trial, researchers compared the effect of a stem cell transplant using a non-myeloablative regimen (a lower-dose, short course of more tolerable immune specific chemotherapy and antibodies to suppress the immune system) versus continuing disease-modifying therapy in 110 patients with relapsing-remitting multiple sclerosis.

Researchers at University of Utah Health conducted a state-by-state analysis to understand the geographic disparities for patients diagnosed with melanoma. The results of their study suggest that lower survival is associated with more practicing physicians in a region and higher population of Caucasians.

Scientists from Sanford Burnham Prebys Medical Discovery Institute (SBP) have demonstrated that muscle stem cells may give rise to rhabdomyosarcoma that occurs during DMD—and identified two genes linked to the tumor’s growth. The research, performed using a mouse model of severe DMD, helps scientists better understand how rhabdomyosarcoma develops in DMD—and indicates that ongoing efforts to develop treatments that stimulate muscle stem cells should consider potential cancer risk. The study was published today in Cell Reports.

People riding free-floating bike share rentals in Seattle are wearing helmets infrequently, according to a new analysis conducted by University of Washington researchers. Only 20 percent of bike share riders wore helmets in the study, while more than 90 percent of cyclists wore helmets while riding their own bikes. Different research on the free-floating bike share systems showed that bikes were usually available in all Seattle neighborhoods across economic, racial and ethnic lines. However, more bikes were located in more-advantaged neighborhoods.

Scientists from Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified an epigenetic marker and two genes that caused heart failure in the children and grandchildren of fruit flies with high-fat-diet-induced heart dysfunction. Reversing the epigenetic modification or over-expressing the two genes protected subsequent generations from the negative heart effects of their parents’ diet. These findings help explain how obesity-related heart failure is inherited and uncover potential targets for treatment. The study was published in Nature Communications on January 14, 2019.
