Rural microbes could boost city dwellers’ health, study finds

Rural microbes could boost city dwellers’ health, study finds

The greater prevalence of asthma, allergies and other chronic inflammatory disorders among people of lower socioeconomic status might be due in part to their reduced exposure to the microbes that thrive in rural environments, according to a new scientific paper co-authored by a University of Colorado Boulder researcher. The article, published in the journal Clinical & Experimental Immunology , argues that people living in urban centers who have less access to green spaces may be more apt to have chronic inflammation, a condition caused by immune system dysfunction Continue reading

Mom’s diet mirrors child’s food allergies

Mom’s diet mirrors child’s food allergies

A long-term study evaluating maternal diet’s impact on food allergy in later life is expected to uncover causes of allergy in children. About 20 million Europeans are subject to food allergies. Continue reading

Development of new cell models that report circadian clock function

Development of new cell models that report circadian clock function

Researchers at the University of Memphis and University of Pennsylvania report the development of robust new liver and fat cell models that report circadian clock function. These models are amenable to high throughput drug screening and could be used to find promising small molecules to resynchronize or help body clocks function normally. The consequences of modern life, eating and staying up later, shift work, cell phone addiction, and travel across time zones, all disturb internal clocks. Continue reading

Cancer cells may respond to mechanical force

Cancer cells may respond to mechanical force

The push and pull of physical force can cause profound changes in the behavior of a cell. Two studies from researchers working at the UNC Lineberger Comprehensive Cancer Center reveal how cells respond to mechanical manipulation, a key factor in addressing the underlying causes of cancer and other diseases.

Patients with paraplegia regain voluntary movement after spinal stimulation

Patients with paraplegia regain voluntary movement after spinal stimulation

Four people with paraplegia are able to voluntarily move previously paralyzed muscles as a result of a novel therapy that involves electrical stimulation of the spinal cord, according to a study funded in part by the National Institutes of Health and the Christopher & Dana Reeve Foundation.

Patients with paraplegia regain voluntary movement after spinal stimulation

Four people with paraplegia are able to voluntarily move previously paralyzed muscles as a result of a novel therapy that involves electrical stimulation of the spinal cord, according to a study funded in part by the National Institutes of Health and the Christopher & Dana Reeve Foundation. The participants, each of whom had been paralyzed for more than two years, were able to voluntarily flex their toes, ankles, and knees while the stimulator was active, and the movements were enhanced over time when combined with physical rehabilitation. Researchers involved in the study say the therapy has the potential to change the prognosis of people with paralysis even years after injury. Continue reading

Does a junk food diet make you lazy? Psychology study offers answer

Does a junk food diet make you lazy? Psychology study offers answer

A new UCLA psychology study provides evidence that being overweight makes people tired and sedentary — not the other way around. Life scientists led by UCLA’s Aaron Blaisdell placed 32 female rats on one of two diets for six months. The first, a standard rat’s diet, consisted of relatively unprocessed foods like ground corn and fish meal. Continue reading

Race now or later? Calculating best time to compete after altitude training

Race now or later? Calculating best time to compete after altitude training

Date: April 3, 2014 Source: American Physiological Society (APS) Summary: A number of studies focus on the optimal time to begin altitude training before competition, but few address the best time to come down from altitude and how long athletes should wait to reacclimatize before competing. Researchers search for the answers in the new review article. Altitude training is a popular practice used by elite athletes to improve endurance in competitions, such as marathons and cycling races, that take place at sea level. Continue reading

Patient stem cells help identify common problem in ALS

Patient stem cells help identify common problem in ALS

Harvard stem cell scientists have discovered that a recently approved medication for epilepsy may possibly be a meaningful treatment for amyotrophic lateral sclerosis (ALS) — Lou Gehrig’s disease, a uniformly fatal neurodegenerative disorder. The researchers are now collaborating with Massachusetts General Hospital to design an initial clinical trial testing the safety of the treatment in ALS patients. The investigators all caution that a great deal needs to be done to assure the safety and efficacy of the treatment in ALS patients, before physicians should start offering it Continue reading
