Uncontrolled hypertension could bring increased risk for Alzheimer's disease Posted: 18 Mar 2013 03:04 PM PDT A new study suggests that controlling or preventing risk factors such as hypertension earlier in life may limit or delay the brain changes associated with Alzheimer's disease and other age-related neurological deterioration.

Pregnant women's likelihood of Cesarean delivery in Massachusetts linked to choice of hospitals Posted: 18 Mar 2013 03:04 PM PDT A new study provides the strongest evidence to date that it's not just medical need that determines who has a Cesarean section, but also something at the hospital level -- in other words, the same woman would have a different chance of undergoing a C-section based on the hospital she chooses.

Millions of people in Asia potentially exposed to health risks of popular herbal medicines Posted: 18 Mar 2013 03:04 PM PDT Scientists are warning that millions of people in Asia may be exposed to risk of developing kidney failure and bladder cancer by taking herbal medicines that are widely available in Asia. The medicines, used for a wide range of conditions including slimming, asthma and arthritis, are derived from a botanical compound containing aristolochic acids.

Heart-healthy lifestyle also reduces cancer risk Posted: 18 Mar 2013 03:04 PM PDT Following the American Heart Association's Life's Simple 7 steps for a healthy heart also reduces cancer risk. Meeting six or seven of the health factors can cut cancer risk in half. The benefits are cumulative, with cancer risk decreasing for each additional factor met.

Human microbe study provides insight into health, disease Posted: 18 Mar 2013 12:16 PM PDT Microbes from the human mouth are telling scientists something about periodontitis and more after they cracked the genetic code of bacteria linked to the condition.

Map of 'shortcuts' between all human genes Posted: 18 Mar 2013 12:16 PM PDT Researchers have generated the full set of distances, routes and degrees of separation between any two human genes, creating a map of gene "shortcuts" that aims to simplify the hunt for disease-causing genes in monogenic diseases.

Elite athletes also excel at some cognitive tasks Posted: 18 Mar 2013 12:16 PM PDT New research suggests that elite athletes -- Olympic medalists in volleyball, for example -- perform better than the rest of us in yet another way. These athletes excel not only in their sport of choice but also in how fast their brains take in and respond to new information -- cognitive abilities that are important on and off the court.

Widespread 'test-and-treat' HIV policies could increase dangerous drug resistance Posted: 18 Mar 2013 12:16 PM PDT One of the most widely advocated strategies for dealing with HIV/AIDS could double the number of multi-drug-resistant HIV cases in the population of men who have sex with men in LA County over the next 10 years, cautions a new study.

Does Greek coffee hold the key to a longer life? Posted: 18 Mar 2013 12:16 PM PDT The answer to longevity may be far simpler than we imagine; it may in fact be right under our noses in the form of a morning caffeine kick. The elderly inhabitants of Ikaria, the Greek island, boast the highest rates of longevity in the world, and many scientists turn to them when looking to discover the 'secrets of a longer life'.

Difficulty in recognizing faces in autism linked to performance in a group of neurons Posted: 18 Mar 2013 12:15 PM PDT Neuroscientists have discovered a brain anomaly that explains why some people diagnosed with autism cannot easily recognize faces -- a deficit linked to the impairments in social interactions considered to be the hallmark of the disorder.

Updated sports concussion guideline: Athletes with suspected concussion should be removed from play Posted: 18 Mar 2013 12:14 PM PDT With more than one million athletes now experiencing a concussion each year in the United States, the American Academy of Neurology (AAN) has released an evidence-based guideline for evaluating and managing athletes with concussion. This new guideline replaces the 1997 AAN guideline on the same topic.

Programmed destruction: Same signaling enzymes can trigger two different processes in the cell Posted: 18 Mar 2013 10:30 AM PDT Lab results show the same signaling enzymes can trigger two different processes in the cell, sounding a warning to biomedical researchers.

Food memories can help with weight loss Posted: 18 Mar 2013 10:30 AM PDT Psychologists have found that using memories of recent meals reduces the amount of food eaten later on. It also found that being distracted when eating leads to increased consumption.

Similar neuro outcomes in preterm infants with low-grade brain bleeding as infants with no bleeding Posted: 18 Mar 2013 10:30 AM PDT A new study suggests that preterm infants with a low-grade bleeding in the brain may have similar neurodevelopmental outcomes as infants with no bleeding.

Only one-third of parents follow doctors' orders for kids all of the time Posted: 18 Mar 2013 10:28 AM PDT One in 10 say they follow pediatricians' advice 'only occasionally;' most likely to ignore guidance on discipline, sleep, watching TV.

Pneumonia patients nearly twice as likely to suffer from depression, impairments Posted: 18 Mar 2013 10:26 AM PDT Long-term cognitive and functional impairments that follow pneumonia hospitalization are comparable to the negative health effects of heart disease.

Oral estrogen hormone therapy linked to increased risk of gallbladder surgery in menopausal women Posted: 18 Mar 2013 10:26 AM PDT Oral estrogen therapy for menopausal women is associated with an increased risk of gallbladder surgery, according to a large-scale study of more than 70 000 women in France).

How some prostate tumors resist treatment, and how it might be fixed Posted: 18 Mar 2013 10:26 AM PDT Researchers have discovered that the protein Siah2 keeps a portion of androgen receptors constantly active, allowing prostate cancer cells to resist treatment. Based on this new information, Siah2 could make a promising biomarker for tracking a prostate cancer patient's response to therapy. Inhibiting Siah2's interaction with the androgen receptor complex might also provide a new method for re-sensitizing castration-resistant prostate tumors to hormone therapy.

Depression stems from miscommunication between brain cells; Study challenges role of serotonin in depression Posted: 18 Mar 2013 07:53 AM PDT A new study suggests that depression results from a disturbance in the ability of brain cells to communicate with each other. The study indicates a major shift in our understanding of how depression is caused and how it should be treated. Instead of focusing on the levels of hormone-like brain chemicals, such as serotonin, the scientists found that the transmission of excitatory signals between cells becomes abnormal in depression.
