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.
Plasma coagulation factor VII (FVII), FIX and FX have been shown to be effective antibacterial proteins against drug-resistant gram-negative bacteria and may offer alternative strategies for combating the increasingly urgent global health threat posed by those resistant pathogens.
LONDON – The largest-ever genomics study of Clostridium difficile has found an emerging new species of the bacterium is selected to thrive on a Western sugar-rich diet and to produce high levels of resistant spores, adapting it to maximize transmission in hospitals and other health care facilities.
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.
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.
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.
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.
