Single measures of viral load may overestimate HIV suppression status

A review of data reported to the National HIV Surveillance System through June 2016 suggests that a single measure of viral load may overestimate how many persons with HIV infection have durable viral suppression. The data also showed that some persons who seemed to have received regular care for HIV infection still had viral loads [...]

Scientists prevent neurodegeneration-associated protein clumping in lab study

Scientists report in a new study that by imitating a natural process of cells, they prevented the formation of protein clumps associated with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia. In lab cultures of human and yeast cells, the scientists stopped the harmful clumping of FUS proteins by exposing them to phosphorylation, a process that [...]

MRI contrast agents accumulate in the brain

The International Society for Magnetic Resonance in Medicine (ISMRM) has provided new guidance in the use of contrast agents during MRI scans. Emerging research suggests gadolinium-based contrast agents, injected in a patient’s veins to brighten tissues in MRI images, accumulate in the brain. More than 300 million doses of such drugs have been administered since [...]

Scientists create stem cell therapy for lung fibrosis conditions

A team of scientists from the UNC School of Medicine and North Carolina State University (NCSU) has developed promising research towards a possible stem cell treatment for several lung conditions, such as idiopathic pulmonary fibrosis (IPF), chronic obstructive pulmonary disease (COPD), and cystic fibrosis – often-fatal conditions that affect tens of millions of Americans. In [...]

MRSA survival chances predicted by DNA sequencing the superbug

Sequencing the DNA of the MRSA superbug can accurately identify patients most at risk of death and could help medics develop new treatments as we move towards personalised medicine, say scientists publishing in the journal Nature Microbiology. MRSA is a Staphylococcus aureus bacterium that has become resistant to most types of antibiotics, and up to [...]
