Cranberry juice now unlikely to prevent cystitis, review finds Posted: 16 Oct 2012 05:41 PM PDT Cranberry juice is unlikely to prevent bladder and kidney infections, according to an updated systematic review published in the Cochrane Library. The authors analysed the most up-to-date evidence and concluded that any benefit, if present at all, is likely to be small and only for women with recurrent UTI.

No benefit from routine health checks, review finds Posted: 16 Oct 2012 05:41 PM PDT Carrying out general health checks does not reduce deaths overall or from serious diseases like cancer and heart disease, according to Cochrane researchers. The researchers, who carried out a systematic review on the subject for the Cochrane Library, warn against offering general health checks as part of a public health program.

Shape of urine can indicate prostate issues: Characteristic shape of a man's urine can help diagnose urinary problems Posted: 16 Oct 2012 02:31 PM PDT Scientists have discovered a simple test which uses the biomechanics of the shape of urine to help diagnose urinary problems.

Mother's touch could change effects of prenatal stress Posted: 16 Oct 2012 02:31 PM PDT Scientists have found that mothers who stroke their baby's body in the first few weeks after birth may change the effects that stress during pregnancy can have on an infant's early-life development.

New blood-vessel-generating cell with therapeutic potential discovered Posted: 16 Oct 2012 02:31 PM PDT Researchers in Finland believe they have discovered stem cells that play a decisive role in new blood vessel growth. These stem cells found in blood vessel walls may offer new opportunities in the treatment of cardiovascular diseases, cancer and many other diseases.

Immune response may link social rejection to later health outcomes Posted: 16 Oct 2012 01:32 PM PDT No matter how you look at it, rejection hurts. Experiencing rejection from a boss, a friend, or a partner is difficult for many adults to handle. But adolescents, who are dealing with the one-two punch of biological and social change, may be most vulnerable to its negative effects. A new study examines the immune response as a potential link between social stressors like rejection and later mental and physical health outcomes.

Common birth control device may be cost-effective treatment for early endometrial cancer Posted: 16 Oct 2012 01:32 PM PDT An intrauterine device is effective in treating early-stage endometrial cancer in morbidly obese and high-risk surgery patients, according to researchers, and could lead to a cost-effective treatment for all women with this cancer type.

No benefit from high-dose multivitamins seen for HIV patients receiving antiretroviral therapy Posted: 16 Oct 2012 01:31 PM PDT A new study suggests that for HIV patients receiving highly active antiretroviral therapy (HAART) to treat HIV, there is no benefit from high- vs. standard-dose micronutrient supplementation -- and that, in fact, high-dose supplements may cause harm. The study is the first large randomized trial to look at how high-dose multivitamin supplementation affects clinical outcomes among people on HAART.

Abnormal involuntary eye movements in 'lazy eye' disease amblyopia linked to changes in subcortical regions of the brain Posted: 16 Oct 2012 01:28 PM PDT The neural mechanism underlying amblyopia, also called "lazy eye" is still not completely clear. A new study now reports abnormal eye movements of the lazy eye, which suggests that disturbed functioning of eye movement coordination between both eyes and not primarily the dysfunction of the visual cortex may be a cause of amblyopia.

When leaving your wealth to your sister's sons makes sense Posted: 16 Oct 2012 01:28 PM PDT In some human societies, men transfer their wealth to their sister's sons, a practice that puzzles evolutionary biologists. A new study has produced insights into "matrilineal inheritance."

Common medical screen predicts liver cancer risk in general population Posted: 16 Oct 2012 01:28 PM PDT Enzyme levels in the blood routinely monitored by physicians as liver function indicators are also the best predictor of liver cancer risk for the general population, a team of scientists report.

Cholesterol levels improving among U.S. adults Posted: 16 Oct 2012 01:28 PM PDT An analysis of nationally-representative data indicates that between 1988 and 2010 there has been a trend of declining average levels of total cholesterol, non-high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol for U.S. adults overall.

Lower use of chloride in intravenous fluids for critically ill patients associated with decreased risk of kidney injury Posted: 16 Oct 2012 01:28 PM PDT In a pilot study assessing the effect of different levels of chloride in intravenous fluids administered to critically ill patients in an intensive care unit, restricting the amount of chloride administration was associated with a significant decrease in the incidence of acute kidney injury and the use of renal replacement therapy.

Cold viruses point the way to new cancer therapies Posted: 16 Oct 2012 01:28 PM PDT Cold viruses generally get a bad rap -- which they've certainly earned -- but new findings by a team of scientists suggest that these viruses might also be a valuable ally in the fight against cancer.

Targeting cancers' 'addiction' to cell-cycle proteins shuts down tumors in mice Posted: 16 Oct 2012 11:17 AM PDT Scientists have safely shut down breast cancer and a form of leukemia in mice by targeting abnormal proteins that control cells' growth cycles, and to which the cancers are "addicted."

Attack! Silent watchmen charge to defend the nervous system Posted: 16 Oct 2012 11:17 AM PDT In many pathologies of the nervous system, there is a common event -- cells called microglia are activated from surveillant watchmen into fighters. Now new research provides the first evidence that mechanisms regulated by the Runx1 gene control the balance between the surveillant versus activated microglia states.

Reprogramming cell identity in the pituitary gland: Discovery could lead to new treatments for Cushing's disease Posted: 16 Oct 2012 11:16 AM PDT A team of researchers reprogrammed the identity of cells in the pituitary gland and identified critical mechanisms of epigenetic cell programming. The discovery could eventually lead to new pharmacological targets for the treatment of Cushing's disease.

Exercise may lead to better school performance for kids with ADHD Posted: 16 Oct 2012 10:21 AM PDT A few minutes of exercise can help children with attention deficit hyperactivity disorder perform better academically, according to a new study.

Sickle cell disease: Physics explains how sickling cells make people sick Posted: 16 Oct 2012 10:15 AM PDT Researchers have identified the physical forces in red blood cells and blood vessels underlying the painful symptoms of sickle cell disease. Their experiment, the first to answer a scientific question about sickle cell disease using microfluidics engineering methods, may help future researchers better determine who is at greatest risk of harm from the disease.

New noninvasive test for colorectal cancer shows promise Posted: 16 Oct 2012 10:15 AM PDT A new noninvasive test for colorectal cancer screening demonstrated high sensitivity for detecting colorectal cancer, in particular precancers that are most likely to develop into cancer, according to new data.

Novel discovery links anti-cancer drugs to muscle repair Posted: 16 Oct 2012 09:59 AM PDT Research shows that the IAP-targeting drugs that promote the death of cancer cells also induce the growth and repair of muscle.

Prion protein hints at role in aiding learning and memory Posted: 16 Oct 2012 09:56 AM PDT Scientists have found that the protein called prion helps our brains to absorb zinc, which is believed to be crucial to our ability to learn and the well-being of our memory.

Obese teen boys have up to 50 percent less testosterone than lean boys Posted: 16 Oct 2012 09:52 AM PDT A new study shows for the first time that obese males ages 14 to 20 have up to 50 percent less total testosterone than do normal males of the same age, significantly increasing their potential to be impotent and infertile as adults.

Two-gene test predicts which patients with heart failure respond best to beta-blocker drug Posted: 16 Oct 2012 07:39 AM PDT A landmark paper identifying genetic signatures that predict which patients respond to a life-saving drug for congestive heart failure has just been published. Medical researchers discovered and characterized the two genetic variations that determine how patients are likely to respond to the beta-blocker bucindolol.

Less-invasive method of brain stimulation helps patients with Parkinson's disease Posted: 16 Oct 2012 07:34 AM PDT Electrical stimulation using extradural electrodes—placed underneath the skull but not implanted in the brain—is a safe approach with meaningful benefits for patients with Parkinson's disease, according to new research.

Starvation hormone markedly extends mouse life span, without need for calorie restriction Posted: 16 Oct 2012 07:34 AM PDT A starvation hormone markedly extends life span in mice without the need for calorie restriction.

Young people driving epidemic of prescription drug abuse, study finds; Abuse of nonmedical analgesics up 40 percent Posted: 16 Oct 2012 06:28 AM PDT A new study reveals that today's adolescents are abusing prescription drugs at a rate 40 percent higher than previous generations. That makes it the second most common form of illegal drug use in the U.S. after marijuana.

How 'cleaving' protein drives tumor growth in prostate, other cancers Posted: 16 Oct 2012 06:28 AM PDT Researchers have determined how a protein known as Trop2 drives the growth of tumor cells in prostate and other epithelial cancers. This discovery is important because it may prove essential for creating new therapies that stop the growth of cancer, the researchers said.

Eating lots of carbs, sugar may raise risk of cognitive impairment Posted: 16 Oct 2012 06:21 AM PDT People 70 and older who eat food high in carbohydrates have nearly four times the risk of developing mild cognitive impairment, and the danger also rises with a diet heavy in sugar, researchers have found. Those who consume a lot of protein and fat relative to carbohydrates are less likely to become cognitively impaired, the study found.

Fathers matter when it comes to their teenager's sexual behavior Posted: 16 Oct 2012 05:51 AM PDT A new study suggests that fathers' parenting behavior influences the sexual behavior of their adolescent children, but most parent-based research has neglected to examine the specific role of fathers.

Proteins in DNA damage response network targeted for new therapies, researchers say Posted: 16 Oct 2012 05:51 AM PDT An intricate system to repair DNA damage called the "DNA damage response" (DDR) contains previously unknown components, including proteins that could be targeted as sensitizers for chemotherapy. Some of these targets may already have drugs available that have unrecognized uses in cancer therapy, said the researchers.

Genetic protection against arsenic Posted: 16 Oct 2012 05:50 AM PDT Evolution has not only controlled human development over millions of years, it also has an impact on modern humans. This is one of the conclusions of a study of Argentinian villagers in the Andes, where the water contains high levels of arsenic. A gene variant that produces efficient and less toxic metabolism of arsenic in the body was much more common among the villagers than among other indigenous groups in South or Central America.

Non-coding antisense RNA can be used to stimulate protein production Posted: 16 Oct 2012 05:49 AM PDT While studying Parkinson's disease, an international research group made a discovery which can improve industrial protein synthesis for therapeutic use. They managed to understand a novel function of non-protein coding RNA: the protein synthesis activity of coding genes can be enhanced by the activity of the non-coding one called "antisense."

Menopause does not cause weight gain, but increases belly fat, major review finds Posted: 16 Oct 2012 05:49 AM PDT A comprehensive review by the International Menopause Society has found that going through the menopause does not cause a woman to gain weight. However, the hormonal changes at the menopause are associated with a change in the the way that fat is distributed, leading to more belly (abdominal) fat.

Link between creativity and mental illness confirmed in large-scale Swedish study Posted: 16 Oct 2012 05:49 AM PDT People in creative professions are treated more often for mental illness than the general population, there being a particularly salient connection between writing and schizophrenia, according to researchers whose large-scale Swedish registry study is the most comprehensive ever in its field.

Smoking in cars produces harmful pollutants at levels above WHO indoor air quality standards Posted: 15 Oct 2012 04:36 PM PDT Smoking during car journeys pumps harmful particulate matter into the indoor air space at levels that far exceed World Health Organization guidance -- even when the windows are open or air conditioning is switched on -- finds the largest study of its kind.
