Neutrons produce first direct 3D maps of water during cell membrane fusion

Sep 20 2018 - 00:09
New 3D maps of water distribution during cellular membrane fusion are accelerating scientific understanding of cell development, which could lead to new treatments for diseases associated with cell fusion. Using neutron diffraction at the Department of Energy's Oak Ridge National Laboratory, researchers have made the first direct observations of water in lipid bilayers used to model cell membrane fusion.

Study documents poor mental and physical health in rural borderland community members

Sep 20 2018 - 00:09
The borderlands between the United States and Mexico are home to numerous Mexican and Central American rural communities, with many members living in poverty and frustrated by limited access to basic resources. A study on inequalities and health among foreign-born Latinos in rural borderland communities, led by a researcher at the University of California, Riverside, has found that this population is vulnerable to high stress that negatively impacts its mental and physical health.

Genomic dark matter activity connects Parkinson's and psychiatric diseases

Sep 20 2018 - 00:09
Using a new technique known as laser-capture RNA seq, that involves cutting out dopamine neurons from a human brain section with a laser, investigators from Brigham and Women's Hospital and Harvard Medical School have cataloged more than 70,000 novel elements active in these brain cells. Their results are published this week in Nature Neuroscience.

Investigational steroid mirrors prednisone's benefits while taming its side effects

Sep 20 2018 - 00:09
A head-to-head trial comparing the decades-old steroid, prednisone, and a promising new steroid, vamorolone, finds both act on the same key set of genetic pathways involved in controlling inflammation, indicates a new study led by Children's National Health System researchers. However, the study suggests the new investigational steroid doesn't activate several additional pathways involved in prednisone's bevy of undesirable side effects.

After EMR implementation, surgeons spend less time interacting with patients

Sep 20 2018 - 00:09
Implementing an electronic medical records (EMR) system at an orthopaedic clinic may have unanticipated effects on clinic efficiency and productivity - including a temporary increase in labor costs and a lasting reduction in time spent interacting with patients, reports a study in September 19, 2018 issue of The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.

Full, but still feasting: Mouse study reveals how urge to eat overpowers a signal to stop

Sep 20 2018 - 00:09
A new study explores the mystery of what drives eating past the point of fullness, at the most basic level in the brain. It shows that two tiny clusters of cells battle for control of feeding behavior -- and the one that drives eating overpowers the one that says to stop. It also shows that the brain's own natural opioid system gets involved -- and that blocking it with the drug naloxone can stop over-eating.

A naturally occurring antibiotic active against drug-resistant tuberculosis

Sep 20 2018 - 00:09
A naturally occurring antibiotic called kanglemycin A is effective against Mycobacterium tuberculosis, the bacteria that cause tuberculosis, even in drug-resistant strains, according to an international team of researchers who used chemistry, molecular biology, microbiology, and X-ray crystallography to show how the compound maintains its activity.

Cancer immunotherapy might benefit from previously overlooked immune players

Sep 20 2018 - 00:09
Using a bioinformatics approach, University of California San Diego School of Medicine researchers found that CD4+ T cell's binding partner, a molecule called MHC-II, may have even more influence on emerging tumors than MHC-I, the better known partner of CD8+ T cells. The finding, published September 20 in Cell, may help researchers improve cancer immunotherapies and predict which patients will respond best.

Researchers make major breakthrough in controlling the 3D structure of molecules

Sep 20 2018 - 00:09
Scientists from The Graduate Center of The City University of New York (GC/CUNY) have made a major breakthrough in chemical synthesis that now makes it possible to quickly and reliably modify the 3D structure of molecules used in drug discovery, according to a paper appearing in the current issue of the journal Science. The new method allows scientists to employ cross-coupling reactions to generate new compounds while controlling their 3D architecture.
