Brown fat transplant reversed type 1 diabetes without insulin in non-obese diabetic mice Posted: 01 Jul 2015 12:26 PM PDT Researchers have found embryonic brown fat transplants reversed type 1 diabetes and restored glucose tolerance to normal in non-obese diabetic mice.

Implantable 'artificial pancreas' could help diabetes patients control their blood sugar Posted: 01 Jul 2015 11:09 AM PDT Living with Type 1 diabetes requires constant monitoring of blood sugar levels and injecting insulin daily. The development of an implantable "artificial pancreas" that continuously measures a person's blood sugar, or glucose, level and can automatically release insulin as needed.

Successful heart transplant after using experimental artificial heart Posted: 01 Jul 2015 11:09 AM PDT A 44-year-old woman has received a successful heart transplant, thanks to an experimental Total Artificial Heart designed for smaller patients. The patient is the first person in California to receive the smaller Total Artificial Heart, and the first patient in the world with the device to be bridged to a successful heart transplant.

Poison ivy affects some people more than others Posted: 01 Jul 2015 11:08 AM PDT Three-quarters of the population will get an itchy red rash if exposed to the urushiol oil inside poison ivy's leaves, stem and roots. One-quarter of people will not have any reaction to exposure.

Initial weight loss could predict long-term success Posted: 01 Jul 2015 11:08 AM PDT New research using data from the reputable Look AHEAD study suggests doctors may want to look at results from a patient's first two months of intensive lifestyle intervention (ILI) to help predict his or her long-term success. These secondary analyses examined the association between initial weight loss (first two months of treatment) and long-term weight loss (eight years after initial treatment).

Brain activity predicts promiscuity and problem drinking Posted: 01 Jul 2015 10:33 AM PDT A new pair of brain-imaging studies suggest that researchers may be able to predict how likely young adults are to develop problem drinking or risky sexual behavior in response to stress. The research is part of the ongoing Duke Neurogenetics Study or DNS, which began in 2010 to better understand how interactions between the brain, genome, and environment shape risky behaviors predicting mental illnesses including depression, anxiety, and addiction.

Regenerative medicine biologists discover a cellular structure that explains fate of stem cells Posted: 01 Jul 2015 10:33 AM PDT Researchers have found a previously unidentified mechanism that helps explain why stem cells undergo self-renewing divisions but their offspring do not.

Humans evolved to be taller and faster-thinking, study suggests Posted: 01 Jul 2015 10:33 AM PDT People have evolved to be smarter and taller than their predecessors, a study of populations around the world suggests.

Human brain study sheds light on how new memories are formed Posted: 01 Jul 2015 09:33 AM PDT In the first study of its kind researchers found that neurons in a specific brain region play a key role in rapidly forming memories about every day events, a finding that may result in a better understanding of memory loss and new methods to fight it in Alzheimer's and other neurological diseases.

Electrical nerve stimulation can reverse spinal cord injury nerve damage in patients Posted: 01 Jul 2015 08:53 AM PDT Researchers find that nerve stimulation can improve the function of peripheral nerves damaged by spinal cord injury (SCI). This technique may be a new approach to preventing long-term changes in nerve and muscle function after SCI and improving SCI rehabilitation outcomes.

Boys more likely to have antipsychotics prescribed, regardless of age Posted: 01 Jul 2015 08:48 AM PDT Boys are more likely than girls to receive a prescription for antipsychotic medication regardless of age, researchers have found. Approximately 1.5 percent of boys ages 10-18 received an antipsychotic prescription in 2010, although the percentage falls by nearly half after age 19. Among antipsychotic users with mental disorder diagnoses, attention deficit hyperactivity disorder was the most common among youth ages 1-18, depression was the most common diagnosis among young adults ages 19-24 receiving antipsychotics.

Indoor tanning rates drop among US adults Posted: 01 Jul 2015 08:47 AM PDT Indoor tanning rates dropped among adults from 5.5 percent in 2010 to 4.2 percent in 2013, although an estimated 7.8 million women and 1.9 million men still engage in the practice, which has been linked to increased cancer risk, according to the results of a new study.

Warts and all: How St. John's Wort can make you sick Posted: 01 Jul 2015 06:38 AM PDT St John's Wort can produce the same adverse reactions as antidepressants, and serious side effects can occur when the two are taken together, according to new research.

Thin colorectal cancer patients have shorter survival than obese patients Posted: 01 Jul 2015 06:38 AM PDT Although being overweight with a high body-mass index has long been associated with a higher risk for colorectal cancer, thinner patients might not fare as well after treatment for advanced cancer, according to a new study.

Evaluation of NK1 antagonists for emesis prevention in oxaliplatin chemo: SENRI trial Posted: 01 Jul 2015 06:37 AM PDT The SENRI trial has opened the window to evaluate NK1 antagonists for emesis prevention in patients taking oxaliplatin chemotherapy, results of a new study.

People with epilepsy can benefit from smartphone apps to manage their condition Posted: 01 Jul 2015 05:30 AM PDT While many people with epilepsy can control their seizures with medication, those unpredictable and involuntary changes in behavior and consciousness can be limiting for others. Neurologists evaluated the application of smartphones in epilepsy care. Apps include seizure diaries as well as medication trackers with reminders to take the next dose of medication. In addition, apps are available to answer any questions patients with epilepsy might have, to detect potential drug interactions and to detect seizures.
