A yoga-based maneuver, reported in the peer-reviewed Topics in Geriatric Rehabilitation, relieves the pain of rotator cuff tear and restores range of motion during one short office visit. The subscapularis muscle takes over for the injured supraspinatus muscle in the rotator cuff. Symptoms usually almost completely disappear.
An international research team led by Dr. Tak Mak, Director, The Campbell Family Institute for Breast Cancer Research at Princess Margaret Hospital (PMH), has discovered a new aspect of “metabolic transformation”, the process whereby tumour cells adapt and survive under conditions that would kill normal cells.
Patients with small kidney tumors are more likely to be offered treatment options based on surgeons’ case volume and type of practice than on tumor characteristics.
A cancer drug already used to treat adults and school-age children with sickle cell anemia is safe and significantly reduces pain and other complications of the disease in children as young as 9 months, according to a national study involving a UT Southwestern Medical Center researcher.
In what is being hailed as a significant advance in the treatment of children with sickle cell anemia, a drug commonly used to treat adults has been shown to be safe and effective in children. A multi-site, placebo-controlled study, conducted in part at the University of Alabama at Birmingham and the Children’s Hospital of Alabama, showed that hydroxyurea reduced episodes of pain and pneumonia in infants and toddlers with sickle-cell disease and reduced hospitalizations and blood transfusions.
1) More progress needed to prevent urban tuberculosis in the U.S.; 2) An increased distrust of health care system is associated with lower utilization of breast and cervical screenings among women; 3) Some social smokers find it difficult to quit.
A little-studied gene known as notum plays a key role in the planarian’s regeneration decision-making process, according to Whitehead Institute scientists. At head-facing wounds, the gene acts as a dimmer switch to dampen the Wnt pathway—an signaling circuit that operates in all animals—and promote head regeneration.
Researchers at the Johns Hopkins Bloomberg School of Public Health have identified a bacterium in field-caught mosquitoes that, when present, stops the development of Plasmodium falciparum, the parasite that causes malaria in humans. According to the study, the Enterobacter bacterium is part of the naturally occurring microbial flora of the mosquito’s gut and kills the parasite by producing reactive oxygen species (or free radical molecules).
Whitehead Institute researchers have found that the planarian flatworm regenerates missing tissues using pluripotent adult stem cells. Until now, scientists could not determine if the dividing cells in planarians are a mix of specialized stem cells that regenerates specific tissues, or if individual neoblasts are pluripotent and able to regenerate all tissues.
In a four-decade, Holy Grail-like quest to fully understand what it means to be in a “supersolid” state, physicists have found that supersolid isn’t always super solid. In other words, this exotic state of frozen helium appears to have liquid-like properties.
A uniquely collaborative study by researchers at the Salk Institute for Biological Studies uncovered a novel mechanism that turns up glucose production in the liver when blood sugar levels drop, pointing towards a new class of drugs for the treatment of metabolic disease.
A collaborative effort by investigators at the Salk Institute for Biological Studies recently revealed just how similarly mammals and insects make critical metabolic adjustments when food availability changes, either due to environmental catastrophe or everyday changes in sleep/wake cycles. Those findings may suggest novel ways to treat metabolic conditions such as obesity and type II diabetes.
Sepsis is a major killer in hospital intensive care units. Researchers at Case Western Reserve University School of Medicine have found that manipulating a genetic factor that can launch or throttle the body’s defenses can improve survival rates during bacterial infection.
The Hubble Space Telescope's Wide Field Camera 3 has taken an image of galaxy NGC 4214. This galaxy glows brightly with young stars and gas clouds, and is an ideal laboratory to study star formation and evolution.
The safety of seafood from the Gulf of Mexico became a central concern following the Deepwater Horizon blowout a year ago. Even after previously closed Gulf waters began reopening in summer 2010, consumer confidence in the safety of Gulf seafood remained shaky. A new review published online May 12 ahead of print in the peer-reviewed journal Environmental Health Perspectives (EHP) affirms that levels of polycyclic aromatic hydrocarbons (PAHs) found thus far in Gulf seafood samples in fact have been well below levels that would be of concern for human health.
