By preventing ice formation while cooling human livers below freezing, researchers have managed to extend the viable lifespan of donated livers threefold.
Telomerase's reputation is that it has an important role in maintaining the ability of stem cells to divide through maintaining telomeres, the structures at the tips of chromosomes that shorten with each replication cycle.
Sexual dimorphism in gene expression is widespread across chromosomes, and is partially conserved across species from mice to humans, the first study to investigate such differences both across species and across tissues has found.
Researchers at the Weizmann Institute and the German Cancer Research Center have identified a role for the gut microbiome in modulating amyotrophic lateral sclerosis (ALS).
The CRISPR genome editing technique has been used to activate a close relative of the gene that is mutated in muscular dystrophy type 1A, preventing development of the disease in mouse-model neonates and reversing symptoms in mice with established pathology.
MEXICO CITY – Ten years after the RV144 "Thai trial" was the first to show that an effective HIV vaccine was possible, three efficacy trials for HIV vaccines are once again underway.
Anorexia nervosa, Cynthia Bulik told BioWorld, has a long-term recovery rate of 25% and “the highest fatality rate of any psychiatric illness.” Those dismal statistics hint at the challenging nature of anorexia nervosa, but also at the shortcomings of current treatment options.
Scientists from the Wellcome Trust Sanger Institute have shown that antioxidant treatment could reverse the competitive advantage of p53-mutated cells in the esophagus of transgenic mice.
Researchers from Johns Hopkins University School of Medicine have developed a machine learning program that could score the risk of pancreatic cysts and recommend one of three treatment strategies – surgery, watchful waiting or discharge without follow-up – more accurately than current methods. The program could potentially reduce the number of unnecessary surgeries performed on pancreatic cysts with little to no potential of turning cancerous.
