Breastfeeding possible deterrent to autism Posted: 06 Nov 2013 05:24 PM PST The emergence of autism in young children appears to result from dysmyelination of brain neurons, related to inadequate supply of insulin-like growth factor (IGF) in the newborn. The deficiency of IGF in affected infants may be due to a combination of genetic and environmental factors yet to be determined. If this hypothesis is correct, breastfeeding in particular could increase IGF levels, thereby compensating for an inborn deficiency of the growth factor.

Clear association between ACE inhibitors, acute kidney injury Posted: 06 Nov 2013 05:22 PM PST New research shows clear association between ACE inhibitors -- drugs used to treat high blood pressure and heart disease -- and acute kidney injury. These and similar drugs are the second most prescribed on the National Health Services in England.

Children who have autism far more likely to have tummy troubles Posted: 06 Nov 2013 05:22 PM PST Children with autism experience gastrointestinal upsets such as constipation, diarrhea and sensitivity to foods six-to-eight times more often than do children who are developing typically, and those symptoms are related to behavioral problems, including social withdrawal, irritability and repetitive behaviors.

Speaking a second language may delay different dementias Posted: 06 Nov 2013 01:25 PM PST In the largest study on the topic to date, research shows that speaking a second language may delay the onset of three types of dementias.

Addicts may be seeking relief from emotional lows more than euphoric highs Posted: 06 Nov 2013 12:24 PM PST Researchers are challenging the commonly held view that drug addiction occurs because users are always going after the high. Based on new animal studies, they say the initial positive feelings of intoxication are short lived -- quickly replaced by negative emotional responses which may be more important in understanding substance abuse.

Researchers and clinicians unite to answer what will it take to achieve an AIDS-free world? Posted: 06 Nov 2013 11:13 AM PST Since the onset of the AIDS pandemic more than three decades ago, researchers from the lab and physicians in the clinic have been working toward one shared goal: an AIDS-free world. This week leading researchers and clinicians discussed recent findings that could bring hope to the estimated 35 million people world-wide who live with HIV.

Multitasking neurons filter and decide: How neural circuits identify information needed for decisions Posted: 06 Nov 2013 11:13 AM PST Using brain recordings and a computer model, an interdisciplinary team confounds the conventional wisdom about how the brain sorts out relevant versus irrelevant sensory inputs in making choices.

Earliest marker for autism found in young infants Posted: 06 Nov 2013 10:20 AM PST Eye contact during early infancy may be a key to early identification of autism, according to a new study. The study reveals the earliest sign of developing autism ever observed -- a steady decline in attention to others' eyes within the first two to six months of life.

New explanation for infection susceptibility in newborns: It is all about helping beneficial bacteria colonize the gut Posted: 06 Nov 2013 10:19 AM PST Cells that allow helpful bacteria to safely colonize the intestines of newborn infants also suppress their immune systems to make them more vulnerable to infections, according to new research. The study could prompt a major shift in how medicine views the threat of neonatal infections -- and how researchers go about looking for new strategies to stop it, said scientists who conducted the study.

Discovery of HIV 'invisibility cloak' reveals new treatment opportunities Posted: 06 Nov 2013 10:19 AM PST Scientists have discovered a molecular invisibility cloak that enables HIV, the virus that causes AIDS, to hide inside cells of the body without triggering the body's natural defense systems.

Reforms urgently needed to streamline road to Alzheimer's Posted: 06 Nov 2013 08:40 AM PST As the burden of Alzheimer's disease escalates worldwide, efforts to develop effective treatments are failing to keep pace because of the high costs and risks associated with developing Alzheimer's drugs. Reforming Alzheimer's drug development, so it is more streamlined and efficient, would bring down costs and speed progress toward approval of drugs that slow or stop the disease.

Customizing treatments for deadly prostate cancer with tumor genomics Posted: 06 Nov 2013 08:38 AM PST A new study is using genomic sequencing to develop customized treatments for men with castration-resistant prostate cancer, a progressive and incurable stage of prostate cancer, which no longer responds to hormone therapies that stop or slow testosterone production.

Genetic aberration paves the way for new treatment of cancer disease Posted: 06 Nov 2013 07:16 AM PST Researchers have characterized a genetic aberration on a group of colorectal cancer patients. The discovery gives hope for a new and efficient treatment of colorectal cancer, which is a frequent and often fatal disease.

Personal reflection triggers increased brain activity during depressive episodes Posted: 06 Nov 2013 07:16 AM PST Research has found that people experiencing depressive episodes display increased brain activity when they think about themselves.

New report calls for sustained public endorsement, funding for human stem cell research Posted: 06 Nov 2013 07:16 AM PST A strategic report from the European Science Foundation examines the key scientific questions for human stem cell research in the context of the rapidly emerging field of regenerative medicine. In parallel to the potential new treatments for incurable diseases resulting from stem cell research, heated ethical and legal debates have arisen across the world.

Identifying young people with type 1 diabetes at risk of heart, kidney disease Posted: 06 Nov 2013 07:16 AM PST Using a simple urine test, researchers can now identify young people with type 1 diabetes at risk of heart and kidney disease.

Comprehending comprehension Posted: 06 Nov 2013 07:16 AM PST What makes a good reader? First, you have to know how to read the words on a page and understand them -- but there's a higher-level step to reading comprehension. You have to tie together the words over time, maintaining their order and meaning in your memory, so that you can understand phrases, sentences, paragraphs and extended texts.

Severe chronic depression more likely in child sex abuse victims Posted: 06 Nov 2013 05:44 AM PST A new study reveals the highest risk variables of chronic depression in the population -- such as having suffered previous episodes of depression, delayed treatment, whether related to other physical or mental health problems, or having suffered sexual abuse during childhood -- affects almost half of patients seeking treatment for depression and carries with it significant problems in terms of disability, suffering and the cost of healthcare.

Unnecessary TB deaths to be thing of the past thanks to mobile drug resistance test device Posted: 06 Nov 2013 05:44 AM PST Thousands of deaths from tuberculosis (or TB), an infectious bacterial disease, could be prevented using a new hand-held device that is being developed to detect potentially fatal drug resistance in less than 15 minutes.

Health benefits of wild blueberries abound Posted: 06 Nov 2013 04:38 AM PST New research shows that regular long-term wild blueberry diets may help improve or prevent pathologies associated with the metabolic syndrome, including cardiovascular disease and diabetes.

Just a few years of early musical training benefits the brain later in life Posted: 05 Nov 2013 02:13 PM PST Older adults who took music lessons as children but haven't actively played an instrument in decades have a faster brain response to a speech sound than individuals who never played an instrument. The finding suggests early musical training has a lasting, positive effect on how the brain processes sound.

Testosterone therapy following angiography linked with increased risk of adverse outcomes Posted: 05 Nov 2013 01:22 PM PST Among a group of men who underwent coronary angiography and had a low serum testosterone level, the use of testosterone therapy was associated with increased risk of death, heart attack, or ischemic stroke, according to a study.
