Homeostasis may have allowed first living cells to maintain internal environment

A Massachusetts General Hospital research team investigating how the earliest stages of life might have developed has discovered a way the first living cells could have met a key challenge -- maintaining a constant internal environment, a process called homeostasis, even when external conditions change.

Scientists map biological networks of genes to gain new insights on disease mechanisms

Innovative software tools allowed the scientists to construct accurate "maps" of gene networks for about 400 different human cell and tissue types, ranging from immune cells to brain tissues, whereas previous studies were limited to just one or few tissues.

Gar genome helps identify genetic sequences shared by human disease genes and zebrafish

Led by Drs John Postlethwait and Ingo Braasch from the Institute of Neuroscience, University of Oregon, US, in collaboration with the Broad Institute, the study of the Spotted Gar (Lepisosteus oculatus) genome reveals that it is small and manageable. Furthermore, it lacks much shuffling and duplication that occurred in the 'main' fish ancestral line; it conserved its genome.

FDA OKs ACR's new Digital Mammography QC Manual

The Food and Drug Administration approved the American College of Radiology's alternative standard request to allow mammography facilities to use the new Digital Mammography Quality Control Manual and Digital Mammography QC Phantom in routine QC of digital equipment. The new manual and phantom will aid in ensuring uniformity of QC testing.

Overprescribing of opioids leads to serious public health problems

Overprescribing of opioids and opioid addiction are serious and growing public health problems in the U.S., and are the focus of a new report by an expert panel, entitled The American Opioid Epidemic: Population Health Implications and Potential Solutions," from the National Stakeholder Panel, Jefferson College of Population Health, which is published in a special supplement to Population Health Management, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The supplement is available open access on the Population Health Managementwebsite

Inherited gene after black plague may help treat HIV patients co-infected with hepatitis C

The Black Death swept Europe in the 14th century eliminating up to half of the population but it left genetic clues that now may aid a University of Cincinnati researcher in treating HIV patients co-infected with hepatitis C using an anti-retroviral drug therapy.

New research sheds light on circadian rhythms

New research sheds light on how the rhythms of daily life are encoded in the brain. Scientists at Washington University School of Medicine in St. Louis have discovered that different groups of neurons, those charged with keeping time, become active at different times of day despite being on the same molecular clock.

Moffitt researchers develop novel therapeutic strategy to keep resistant cells in check

Despite numerous advances in oncology since the War on Cancer began, many patients develop resistance to standard therapies and eventually relapse. Moffitt Cancer Center researchers hope to improve treatment outcomes with development of a novel therapeutic strategy, called adaptive therapy, which is based on evolutionary principals and aims to keep resistant cells in check by maintaining a population of chemo-sensitive cells.
