Omega-3 lowers childhood aggression in short term Posted: 13 May 2016 06:53 PM PDT Consuming omega-3 initially improves a child's aggressive behavior, according to researchers but the effects eventually vanish.

Another reason for wine lovers to toast resveratrol Posted: 13 May 2016 12:03 PM PDT Red wine lovers have a new reason to celebrate. Researchers have found a new health benefit of resveratrol, which occurs naturally in blueberries, raspberries, mulberries, grape skins and consequently in red wine.

Genetic biomarker may predict nerve pain side effects associated with prostate cancer treatment Posted: 13 May 2016 12:03 PM PDT Taxanes are a group of drugs commonly used to treat cancers of the breast, lung, ovary, or prostate, but its use can be limited by significant side effects. Researchers report prostate cancer patients who have a variation in the VAC14 gene are more susceptible to a side effect called peripheral neuropathy when treated with the taxane docetaxel.

Rapid eye movement sleep: Keystone of memory formation Posted: 13 May 2016 10:02 AM PDT For decades, scientists have fiercely debated whether rapid eye movement sleep -- the phase where dreams appear -- is directly involved in memory formation. Now, a study provides evidence that REM sleep does, indeed, play this role -- at least in mice.

Confirmation that the Ebola virus persists in the semen of survivors of the epidemic Posted: 13 May 2016 08:28 AM PDT An international study confirms that Ebola virus persists in the semen of survivors of the epidemic in Guinea, for up to 9 months after their recovery. These results recall the importance of monitoring survivors in order to prevent the risks of new epidemic outbreaks.

Noninvasive monitor assesses patients' response to painful stimulation during surgery Posted: 13 May 2016 08:21 AM PDT A novel measure for assessing the body's response to surgery may allow for better anesthesia management in the O.R., less pain when regaining consciousness from anesthesia and better postoperative outcomes.

American Cancer Society report assesses progress against goals set for nation Posted: 13 May 2016 08:21 AM PDT A new report assesses how the nation fared against the ambitious challenge goal set by the American Cancer Society to reduce the cancer death rates by 50 percent over 25 years ending in 2015.

Bioengineered blood vessel is safe for dialysis patients, study finds Posted: 13 May 2016 08:21 AM PDT Scientists have created bioengineered blood vessels for kidney-disease patients on dialysis. The human-made vessels appeared to be both safe and more durable than commonly used synthetic versions, said the investigators.

Using precision-genetics in pigs to beat cancer Posted: 13 May 2016 08:18 AM PDT Because of their similarities to people, using new technology in pigs turn up as a valuable alternative to rodent models of cancer.

Psychology: The power of expectations on experience of pain Posted: 13 May 2016 08:18 AM PDT Expectations have a lot of power over people as is evidenced by the placebo effect: Patients get pills that have no active ingredient. But the patients are not aware of that. Firmly believing that they are taking an effective drug, they actually get better afterwards. Only their expectations were at play here.

Obesity on the rise in Indonesia Posted: 13 May 2016 07:10 AM PDT Obesity is on the rise in Indonesia, one of the largest studies of the double burden of malnutrition in children has revealed.

Size of brain region is associated with response to PTSD treatment Posted: 13 May 2016 07:08 AM PDT A study has found that PTSD patients with a larger hippocampus -- a region of the brain key to distinguishing between safety and threat -- are more likely to respond to exposure-based therapy for posttraumatic stress disorder.

Prenatal stress could enhance protective mechanisms of babies Posted: 13 May 2016 05:45 AM PDT Maternal stress and depression during pregnancy may activate certain protective mechanisms in babies. Psychologists report that certain epigenetic adaptations in newborns suggest this conclusion.

Blood marker determines who will respond to colorectal cancer drug Posted: 13 May 2016 05:31 AM PDT Cancer researchers have identified a marker that shows up in a blood test that determines which patients with colorectal cancer that has spread would benefit from receiving the drug cetuximab.

New gene for familial high cholesterol Posted: 12 May 2016 06:24 PM PDT The gene that explains one quarter of all familial hypercholesterolemia with very high blood cholesterol, has been revealed by new research. Familial hypercholesterolemia is the most common genetic disorder leading to premature death, found in 1 in 200 people.

Brain images reveal first physical evidence that AA prayers reduce cravings Posted: 12 May 2016 11:29 AM PDT Members Alcoholics Anonymous who recited AA prayers after viewing drinking-related images reported less craving for alcohol after praying, according to a new study.

Study finds low levels of ultraviolet A light protection in automobile side windows Posted: 12 May 2016 09:49 AM PDT An analysis of the ultraviolet A (UV-A) light protection in the front windshields and side windows of automobiles finds that protection was consistently high in the front windshields while lower and highly variable in side windows, findings that may in part explain the reported increased rates of cataract in left eyes and left-sided facial skin cancer, according to a new study.

Repetitive, subconcussive head impacts from football associated with short-term changes in eye function Posted: 12 May 2016 09:49 AM PDT In a study that included 29 NCAA football players, repetitive subconcussive impacts were associated with changes in near point of convergence (NPC) ocular-motor function among players in the higher-impact group, although NPC was normalized after a 3-week rest period, according to a new study. The NPC measures the closest point to which one can maintain convergence (simultaneous inward movement of eyes toward each other) while focusing on an object before diplopia (double vision) occurs.

Gene therapy against brain cancer Posted: 12 May 2016 07:27 AM PDT Applying gene therapy to glioblastoma appears to be a very promising treatment, say researchers. Tests in vitro and in vivo on mice provided very clear-cut results, and modelling demonstrates that the treatment targets at least six different points of tumor metabolism. Gene therapy, a technique that selectively attacks a tumor, might provide hope in the fight against this type of deadly cancer, for which surgery is practically impossible and chemo- and radiotherapy are ineffective against very aggressive recurrences.
