Researcher develops, proves effectiveness of new drug for spinal muscular atrophy

Researcher develops, proves effectiveness of new drug for spinal muscular atrophy

According to recent studies, approximately one out of every 40 individuals in the United States is a carrier of the gene responsible for spinal muscular atrophy (SMA), a neurodegenerative disease that causes muscles to weaken over time. Continue reading

Researcher develops, proves effectiveness of new drug for spinal muscular atrophy

According to recent studies, approximately one out of every 40 individuals in the United States is a carrier of the gene responsible for spinal muscular atrophy (SMA), a neurodegenerative disease that causes muscles to weaken over time. Now, researchers at the University of Missouri have made a recent breakthrough with the development of a new compound found to be highly effective in animal models of the disease Continue reading

New producer of crucial vitamin B12 discovered

New producer of crucial vitamin B12 discovered

New research has determined that a single group of micro-organisms may be responsible for much of the world’s vitamin B 12 production in the oceans, with implications for the global carbon cycle and climate change. Although vitamin B 12 is an essential molecule required by most life on this planet, it is only produced by a relatively small group of micro-organisms because it is so large and complex Continue reading

Cells put off protein production during times of stress

Cells put off protein production during times of stress

Living cells are like miniature factories, responsible for the production of more than 25,000 different proteins with very specific 3-D shapes. And just as an overwhelmed assembly line can begin making mistakes, a stressed cell can end up producing misshapen proteins that are unfolded or misfolded. Now Duke University researchers in North Carolina and Singapore have shown that the cell recognizes the buildup of these misfolded proteins and responds by reshuffling its workload, much like a stressed out employee might temporarily move papers from an overflowing inbox into a junk drawer Continue reading

In one of nature’s innovations, a single cell smashes and rebuilds its own genome

In one of nature’s innovations, a single cell smashes and rebuilds its own genome

Life can be so intricate and novel that even a single cell can pack a few surprises, according to a study led by Princeton University researchers. The pond-dwelling, single-celled organism Oxytricha trifallax has the remarkable ability to break its own DNA into nearly a quarter-million pieces and rapidly reassemble those pieces when it’s time to mate, the researchers report in the journal Cell.

Targeting protein-making machinery to stop harmful bacteria

Targeting protein-making machinery to stop harmful bacteria

One challenge in killing off harmful bacteria is that many of them develop a resistance to antibiotics. Continue reading

Each day in hospital raises risk of multidrug-resistant infection

Each day in hospital raises risk of multidrug-resistant infection

If a patient contracts an infection while in the hospital, each day of hospitalization increases by 1% the likelihood that the infection will be multidrug-resistant, according to research presented at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) an infectious disease meeting of the American Society for Microbiology. Researchers from the Medical University of South Carolina gathered and analyzed historical data from 949 documented cases of Gram-negative infection at their academic medical center Continue reading

New antifungal as effective as existing drugs with fewer adverse events

New antifungal as effective as existing drugs with fewer adverse events

A newly developed antifungal, isavuconazole, is as effective as an existing drug, voriconazole, against invasive mold disease in cancer patients with less adverse effects, according to phase 3 clinical data presented at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy, an infectious disease meeting of the American Society for Microbiology.
