Nearly 80 percent of trauma centers in the United States that serve predominantly minority patients have higher-than-expected death rates, according to new Johns Hopkins research. Moreover, the research shows, trauma patients of all races are 40 percent less likely to die — regardless of the severity of their injuries — if they are treated at hospitals with lower-than-expected mortality rates, the vast majority of which serve predominantly white patients.
Researchers have figured out the specific job of a protein long implicated in tumors of the nervous system. Their new study details what they call the “matchmaking” activities of a fruit fly protein called Merlin, whose human counterpart, NF2, is a tumor suppressor protein known to cause neurofibromatosis type II when mutated.
A University of Colorado Cancer Center study published today in the journal Cancer shows that the current criteria used to match lung cancers with the drug crizotinib may miss some patients who could benefit from the drug.

Like volunteers handing out cups of energy drinks to marathon runners, specially engineered “helper cells” transplanted along with stem cells can dole out growth factors to increase the stem cells’ endurance, at least briefly, Johns Hopkins researchers report. Their study, published in the September issue of Experimental Neurology, is believed to be the first to test the helper-cell tactic, which they hope will someday help to overcome a major barrier to successful stem cell transplants.
By creating a powerful new gene regulation system called CRISPR-on, Whitehead Institute researchers now have the ability to increase the expression of multiple genes simultaneously and precisely manipulate each gene’s expression level. The system is effective in both mouse and human cells as well as in mouse embryos.

Their discoveries, described in a paper published online in Nature Neuroscience on August 25, also overturn established ideas about the role of a protein considered key to the disease’s progress.
A $1.3 million grant from the National Institute of Neurological Disorders and Stroke could help Houston Methodist scientists better understand how the body's own immune system drives multiple sclerosis.
Much of modern agriculture relies on biologically available nitrogenous compounds (called “fixed” nitrogen) made by an industrial process developed by German chemist Fritz Haber in 1909. Himadri Pakrasi, PhD, a scientist at Washington University in St. Louis, thinks it should be possible to design a better nitrogen-fixing system. His idea is to put the apparatus for fixing nitrogen in plant cells, the same cells that hold the apparatus for capturing the energy in sunlight. The National Science Foundation just awarded Pakrasi and his team $3.87 million to explore this idea further.
A drug used to treat blood cancers may also stop the spread of invasive breast cancer, researchers at Mayo Clinic in Florida have discovered.
Prescribing of “atypical” antipsychotic medications to children and young adults with behavioral problems or mood disorders may put them at unnecessary risk for type 2 diabetes, a Vanderbilt University Medical Center study shows. Young people using medications like risperidone, quetiapine, aripiprazol and olanzapine led to a threefold increased risk of developing type 2 diabetes within the first year of taking the drug, according to the study published Aug. 21 in the journal JAMA Psychiatry.

While children of all ages will be heading back to school in a few days, a new study from the Université de Montréal may encourage their parents to return to the classroom themselves ... at least for a few evenings! The results of a study in developmental psychology published in the Journal of Child and Family Studies show that the How-to Parenting Program improves the mental health of children.
Biomedical engineers have created a new drug-delivery strategy for a type of central vision loss caused by blood vessel growth at the back of the eye, where such growth should not occur. The team gave the drug a biodegradable coating to keep it in the eye longer. If effective in humans, monthly needle sticks to the eye, which are the current standard of care, could be replaced with only two or three injections per year.
By determining the three-dimensional structure of proteins at the atomic level, researchers at the National Institutes of Health have discovered how some commonly used flame retardants, called brominated flame retardants (BFRs), can mimic estrogen hormones and possibly disrupt the body’s endocrine system. BFRs are chemicals added or applied to materials to slow or prevent the start or growth of fire.
By studying the planarian flatworm, a master of regenerating missing tissue and repairing wounds, the lab of Whitehead Institute Member Peter Reddien has identified an unexpected source of position instruction: the muscle cells in the planarian body wall. This is the first time that such a positional control system has been identified in adult regenerative animals.
Sympathetic neurons “cross-talk” -- or engage in reciprocal signaling -- with the tissues they connect to. And when they don't, there's trouble.
Five Creighton researchers will study a form of fat that surrounds the heart. They believe this fat undergoes a chemical change in some obese patients, which could be the cause behind the narrowing of arteries and development of heart disease.

Black patients preoccupied with racial concerns have higher blood pressure than those who aren’t, according to results of new Johns Hopkins-led research. The findings suggest that heightened race consciousness could at least in part account for the disproportionately high rate of hypertension in black Americans — the highest prevalence of any group in the United States and one of the highest rates in the world.
Researchers at Johns Hopkins have uncovered a protein switch that can either increase or decrease memory-building activity in brain cells, depending on the signals it detects. Its dual role means the protein is key to understanding the complex network of signals that shapes our brain’s circuitry, the researchers say.
