A sensitive subject
Type an email on your computer. Raise a glass to your lips. Feel for the light switch in a dark room. Simple, everyday tasks can demand subtle interactions between our hands and our surroundings, but, surprisingly, much remains unknown about the mechanics of the sense of touch. Most people don t have a very clear picture of how touch sensation actually arises, said UC Santa Barbara faculty member Yon Visell, an assistant professor in the Department of Elec ...

Stem cells used to successfully regenerate damage in corticospinal injury
Writing in the March 28, 2016 issue of Nature Medicine , researchers at University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System, with colleagues in Japan and Wisconsin, report that they have successfully directed stem cell-derived neurons to regenerate lost tissue in damaged corticospinal tracts of rats, resulting in functional benefit. The corticospinal projection is the most important motor system in humans ...

New computational method reveals significant degeneration of knee cartilage in...
Osteoarthritis is a degenerative disease in which the articular cartilage protecting the joint starts to degenerate and wear off over time. The main risk factors of osteoarthritis are advanced age and overweight-induced significant stresses on the knee joint. Current imaging methods such as MRI and X-ray provide information about the thickness and composition of the cartilage, but they do not provide a quantitative estimate of the patient-specific risk of ...

Gene variants found to strongly improve bone density in girls
Pediatric researchers have found that rare genetic changes strongly increase the likelihood that a child will have higher bone density, but only in girls. Because childhood and adolescence are critical periods for bone formation, these gene variants play an important role in increasing bone strength and reducing vulnerability to fractures later in a woman s life. We investigated whether the same gene variants that strongly affect bone density in adults als ...

Ultrasound-estimated fat content in muscles may be an indicator of physical he...
Ultrasound-estimated percent intramuscular fat of muscles in the lower extremity was inversely associated with physical activity level and positively associated with body mass index in a recent study. Ultrasound is advantageous because it is less costly and more accessible when compared with other imaging technologies. The Muscle Nerve study included 42 participants 16 men, 26 women between the ages of 19 and 68 years, with a wide range of body mass index ...

Use of mindfulness-based stress reduction for chronic low back pain
Among adults with chronic low back pain, both mindfulness-based stress reduction and cognitive behavioral therapy resulted in greater improvement in back pain and functional limitations when compared with usual care, according to a study appearing in the March 22 29 issue of JAMA . Low back pain is a leading cause of disability in the United States. There is need for treatments with demonstrated effectiveness that are low risk and have potential for widesp ...

Health effects of sit-stand desks, interventions aimed to reduce sitting at wo...
An updated Cochrane Review , published today in the Cochrane Library, says that the benefits of a variety of interventions intended to reduce sitting at work are very uncertain. Millions of people worldwide sit at a desk all day, and over recent years this has led to increased levels of physical inactivity in the work place. Health experts have warned that long periods of sitting can increase the risk of heart disease and obesity. There are a number of dif ...

Stem cell therapy reverses age-related osteoporosis in mice
Toronto, ON - Imagine telling a patient suffering from age-related type-II osteoporosis that a single injection of stem cells could restore their normal bone structure. This week, with a publication in STEM CELLS Translational Medicine, a group of researchers from the University of Toronto and The Ottawa Hospital suggest that this scenario may not be too far away. Osteoporosis affects over 200M people worldwide and, unlike post-menopausal type-I osteoporos ...

Excessive fat in legs of children with spina bifida suggests risk for metaboli...
Children with a severe type of spina bifida called myelomeningocele have a high prevalence of obesity and excess fat accumulation in their lower extremities. In a study designed to assess bone, muscle and fat tissue distribution in the lower legs of children with this disease, researchers at Children s Hospital Los Angeles determined that this excess fat tissue is within the muscle boundary muscle-associated rather than subcutaneous. These findings are sig ...
