(Brigham and Women's Hospital) Investigators at Brigham and Women's Hospital and the Harvard Program in Therapeutic Sciences at Harvard Medical School have assessed environmental exposure to multiple toxins in children living in a region of Mexico with a high incidence of chronic kidney disease, especially among young adults.
(University of Maryland Medical Center) Researchers investigating a novel device to repair the mitral heart valve, report 100 percent procedural success in a safety and performance study, the first such study done in humans. The image-guided device, based on technology developed at the University of Maryland School of Medicine, is deployed through a tiny opening in a beating heart, avoids open-heart surgery, automates a key part of the valve repair process, simplifies the procedure and reduces operating room time.
(Moscow Institute of Physics and Technology) Incorrect behavior of proteins in cells is a cause of many dangerous illnesses, such as cancer or the Alzheimer's disease. Understanding protein-protein interactions is essential for finding the cure to them. Scientists from MIPT have created a new method to predict possible protein configurations in cells, which is a hundred times faster than any of the previously developed algorithms.This fact makes the algorithm a viable substitution to an experimental approach.
(Massachusetts General Hospital) A team of researchers from the Massachusetts General Hospital Center for Engineering in Medicine have created a 'liver on a chip,' a model of liver tissue that replicates the metabolic variations found throughout the organ and more accurately reflects the distinctive patterns of liver damage caused by exposure to environmental toxins, including pharmaceutical overdose.
(Georgia State University) The loss of private health insurance from an employer can lead to poorer mental and physical health as older adults transition to early retirement, according to a study by Georgia State University.
(The Hastings Center) During the recent Ebola outbreak, scientific developments involving infection challenge experiments on nonhuman primates (NHPs) sparked hope that successful treatments and vaccines may soon become available. Yet these studies intentionally expose sophisticated animals to severe suffering and a high risk of death. Should research on NHPs other than great apes be subject to tighter restrictions than it currently is?
(University of Missouri-Columbia) Americans spend more than 60 billion dollars a year on weight loss products; two-thirds of these dieters are estimated to regain more weight within four or five years than they originally lost according to the Live Strong Foundation. A new book from a University of Missouri researcher provides an innovative and effective program to help people adopt healthy eating habits by mindfully listening to their body's needs, without giving up food.
(Wiley) A new study has revealed a relationship between chronic periodontitis and lacunar infarct, two common diseases in the elderly. Chronic periodontitis is an inflammatory disease of the gums, whereas lacunar infarct is a type of cerebral small vessel disease that can lead to a stroke.
(RAND Corporation) A new study finds that the Veterans Affairs health care system generally performs better than or similar to other health care systems on providing safe and effective care to patients. The project was part of an assessment of the VA health system mandated by the US Congress after reports that veterans faced long delays for care at some VA health facilities.
(NorthShore University HealthSystem) Researchers have launched the first clinical trial to investigate a genetic risk score to predict the risk of breast, prostate and colorectal cancer.
(Wiley) In a study of patients with hypertension, those with resistant hypertension -- meaning that their blood pressure remained elevated despite concurrent use of three antihypertensive agents of different classes -- had a higher rate of sleep apnea (9.6 percent) than those without resistant hypertension (7.2 percent).
(Drexel University) Drexel University researchers found a huge disparity between the price of soda, which is linked to the prevalence of health issues like diabetes, and milk -- a difference in price that could be narrowed by taxes like the one on sugary drinks recently approved in Philadelphia.
(Wiley) Patients with irritable bowel syndrome (IBS) are often concerned that certain foods may trigger or worsen their symptoms, which can include abdominal pain, diarrhea, or constipation. In a new study, patients who ate rye bread that was low in so-called 'FODMAPs' (fermentable oligo- di- and mono-saccharides and polyols) experienced milder IBS symptoms than patients who ate normal rye bread.
(International Communication Association) Researchers at Indiana University, examined portrayals of playable female characters from 1983 to 2014. They found that sexualization of female characters peaked in the 1990s and have diminished since 2007.
(George Washington University) The GW Cancer Center received a $1 million dollar grant from the Pfizer Foundation to advance equitable, patient-centered cancer care by providing resources for patients and health care providers to have improved conversations, including a focus on patient health literacy, and cultural sensitivity.
(California Institute of Technology) Scientists are learning how cells make the decision to become T cells.
(Loyola University Health System) Four Loyola Medicine physicians have been named to Negocios Now's 2016 'Who's Who in Hispanic Chicago.'Loyola has more physicians on the list than any other medical center. Negocios Now, a national award-winning business publication, develops a list each year of the most prominent Hispanics in the Chicago area.
(University of California - Los Angeles Health Sciences) A study from the UCLA AIDS Institute and Center for AIDS Research suggests that recently discovered potent antibodies can be used to generate a specific type of cell called chimeric antigen receptors, or CARs, that can be used to kill cells infected with HIV-1.
(Columbia University Medical Center) Scientists have captured new images of a calcium-shuttling molecule that has been linked to aggressive cancers. The three-dimensional structure could help researchers develop novel therapies and diagnostic tools for diseases that are caused by a malfunction in calcium adsorption.
(Harvard Medical School) Harvard Stem Cell Institute researchers have found evidence that bone marrow transplantation may one day be beneficial to a subset of amyotrophic lateral sclerosis.The data suggests the most common genetic mutation associated with ALS plays an important role in not only the nervous system, but also the blood and immune systems.
