Enzyme Involved In Glioblastomas Identified, Offers A Possible Key To Developing Tissue Regeneration Therapy
Date: Jan-21-2013One of the most common types of brain tumors in adults, glioblastoma multiforme, is one of the most devastating. Even with recent advances in surgery, radiation and chemotherapy, the aggressive and invasive tumors become resistant to treatment, and median survival of patients is only about 15 months. In a study published in Neuro-Oncology, researchers at Mayo Clinic identify an important association between the naturally occurring enzyme Kallikrein 6, also known as KLK6, and the malignant tumors...
Steroids Versus Botox For Painful Foot Condition, Plantar Fasciitis
Date: Jan-21-2013Plantar fasciitis is the most frequent cause of chronic heel pain, leaving many sufferers unable to put their best foot forward for months at a time. Now a Mexican study suggests that physicians should turn to Botox rather than steroids to offer patients the fastest road to recovery. The research appears in the journal Foot & Ankle International, published by SAGE. Plantar fasciitis results when connective tissues on the sole of the foot, the plantar fascia, become painfully inflamed...
Links Challenged Between Day Care And Behavioral Issues
Date: Jan-21-2013A new study that looked at more than 75,000 children in day care in Norway found little evidence that the amount of time a child spends in child care leads to an increase in behavioral problems, according to researchers from the United States and Norway. Several prior studies in the U.S. made connections between the time a child spends in day care and behavioral problems, but the results from Norway contradict those earlier findings, the researchers report in the online version of the journal Child Development...
New Test Brings Hearing-Loss-Prevention Drugs Closer To Reality
Date: Jan-21-2013A new way to test anti-hearing-loss drugs in people could help land those medicines on pharmacy shelves sooner. University of Florida researchers have figured out the longstanding problem of how to safely create temporary, reversible hearing loss in order to see how well the drugs work. The findings are described in a recent issue of the journal Ear & Hearing. "There's a real need for drug solutions to hearing loss," said lead investigator Colleen Le Prell, Ph.D...
Personality Psychology Improves Understanding Of Decision-Making, Longevity, And Mental Health
Date: Jan-21-2013Extraversion does not just explain differences between how people act at social events. How extraverted you are may influence how the brain makes choices - specifically whether you choose an immediate or delayed reward, according to a new study. The work is part of a growing body of research on the vital role of understanding personality in society...
Simple Interventions Can Drastically Reduce Amputations Among Diabetics
Date: Jan-21-2013Every 30 seconds somebody in the world is amputated as a consequence of foot complication due to diabetes. A new study at Sahlgrenska Academy, University of Gothenburg, Sweden, confirmes that shoe inserts, podiatry, regular checkups and other simple interventions can reduce the number of amputations by more than 50%. Orthotic researchers at Sahlgrenska Academy, University of Gothenburg, have studied diabetic foot complications ever since 2008...
Rising Meat Consumption, Calorie Intake Complicate Efforts To Conserve Essential Phosphorus Resource
Date: Jan-21-2013Dietary changes since the early 1960s have fueled a sharp increase in the amount of mined phosphorus used to produce the food consumed by the average person over the course of a year, according to a new study led by researchers at McGill University. Between 1961 and 2007, rising meat consumption and total calorie intake underpinned a 38% increase in the world's per capita "phosphorus footprint," the researchers conclude in a paper published online in Environmental Research Letters...
Discovery May Lead To New Treatments For Deadly Sleeping Sickness
Date: Jan-21-2013While its common name may make it sound almost whimsical, sleeping sickness, or African trypanosomiasis, is in reality a potentially fatal parasitic infection that has ravaged populations in sub-Saharan Africa for decades, and it continues to infect thousands of people every year. Few drugs have been developed to treat sleeping sickness since the 1940s, and those still in use are highly toxic, sometimes causing painful side effects and even death...
Burnout In Middle-Aged Women
Date: Jan-21-2013Emotional exhaustion and physical and cognitive fatigue are signs of burnout, often caused by prolonged exposure to stress. Burnout can cause negative health effects including poor sleep, depression, anxiety, and cardiovascular and immune disorders. The findings of a 9-year study of burnout in middle-aged working women are reported in an article in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available on the Journal of Women's Health website...
Method For More Sensitive Electrochemical Sensors Could Open Up A New Class Of Technologies Impacting Medicine, Chemistry, Engineering
Date: Jan-21-2013Graphene and related materials hold promise for the future of electrochemical sensors - detectors that measure the concentration of oxygen, toxic gases, and other substances - but many applications require greater sensitivity at lower detection ranges than scientists have been able to achieve. A Northwestern University research team and partners in India have recently developed a new method for amplifying signals in graphene oxide-based electrochemical sensors through a process called "magneto-electrochemical immunoassay...
