For many older adults, the aging process seems to go hand-in-hand with an annoying increase in clumsiness. New research from Washington University in St. Louis suggests some of these reaching-and-grasping difficulties may be caused by changes in the mental frame of reference that older adults use to visualize nearby objects.
Scientists, like Buddhist monks and Zen masters, have known for years that meditation can reduce anxiety, but not how. Researchers at Wake Forest Baptist Medical Center, however, have succeeded in identifying the brain functions involved.
Johns Hopkins researchers have documented huge and somewhat puzzling interstate variations in the percentage of emergency versus elective bowel surgeries. Figuring out precisely why the differences occur is critical, they say, because people forced to undergo emergency procedures are far more likely to die from their operations than those able to plan ahead for them.
Investigators at Duke Medicine and UCSF have been selected by NIAID to oversee a nationwide research program on antibacterial resistance. Duke has been awarded $2 million in initial funding to launch the network; total funding for the award will reach at least $62 million through 2019.
Researchers in the Perelman School of Medicine at the University of Pennsylvania have determined the role of a key growth factor, found in limited quantities in human skin cells, that helps hair follicles form and regenerate during the wound healing process. When this growth factor, called Fgf9, was overexpressed in a mouse model, there was a two- to three-fold increase in the number of new hair follicles produced. Researchers believe that this growth factor could be used therapeutically for people with various hair and scalp disorders. The study appears in an advance online publication of Nature Medicine.
The military has for decades used sonar for underwater communication. Now, researchers at the University at Buffalo are developing a miniaturized version of the same technology to be applied inside the human body to treat diseases such as diabetes and heart failure in real time.
Researchers are targeting a possible new weapon in the fight against malaria, science that could also be applied in the fight against other devastating mosquito-borne illnesses, according to a Vanderbilt study published in PLOS ONE.
The temporary placement of umbrella-like, metal mesh filters in abdominal veins to stop potentially lethal blood clots from traveling to the lungs during and after weight loss surgery may actually increase the risk of death in morbidly obese patients, according to new Johns Hopkins research.
A University of Missouri scientist has discovered that by combining cells from bone marrow with a new drug may help cure type 1 diabetes. The discovery is reported in the current online issue of Diabetes.
Johns Hopkins scientists report that a 10-minute test for “frailty” first designed to predict whether the elderly can withstand surgery and other physical stress could be useful in assessing the increased risk of death and frequent hospitalization among kidney dialysis patients of any age.
Strength training may help older individuals manage knee pain associated with knee osteoarthritis. A new study at Wake Forest University is developing a surgery-free and effective option to treat knee pain and loss of mobility associated with knee osteoarthritis.
Specialized cells, called “hematopoietic stem cells,” produce the new blood cells. Scientists thought hematopoietic stem cells stayed in the bone marrow but recent research has revealed that they, too, travel to the problem site: to the heart if a heart attack is in progress, or to the brain in the case of a stroke. Why these cells leave the bone marrow, how they know where to go, and what they do when they reach their target is what Jennifer Gillette, PhD, will use her $300,000 American Heart Association grant to study over the next four years.
The protein GATA-3 plays an important role in mammalian immune response, but its overall function in cell development and cancer formation is not well understood. In an effort to further define the importance of GATA-3, researchers at the University of North Carolina have traced how the protein performs important functions in CD8+T-cell type of the immune system.
Gender specific shifts in cardiac metabolism under stress may shed light on heart disease.
