Scientists make advance in cancer research Posted: 03 Jan 2014 05:53 AM PST A protein that has been at the center of cancer drug design for the last 20 years should not be overlooked according to new research.

Alternative to yogurt Posted: 03 Jan 2014 05:53 AM PST Researchers have obtained new products fermented with probiotic bacteria from grains and nuts - what is known as plant-based or vegetable "milks" - which are an alternative to conventional yogurts. The products are specially designed for people with allergies to cow's milk, lactose or gluten intolerance, as well as children and pregnant women.

Nordic study: few persons with metabolic syndrome adhere to nutrition recommendations Posted: 03 Jan 2014 05:53 AM PST Adherence to dietary recommendations is weak among people suffering from metabolic syndrome or having increased risk for metabolic syndrome, according to the Nordic SYSDIET study. In most cases, the diet is too high in salt and saturated fat, and too low in dietary fibre and unsaturated fat; many don't have enough vitamin D. Metabolic syndrome is becoming increasingly widespread, and is associated increased risk of diabetes and cardiovascular diseases. Adherence to dietary recommendations is of vital importance for those belonging to this risk group.

Higher vitamin D levels in pregnancy could help babies become stronger Posted: 03 Jan 2014 05:52 AM PST Children are likely to have stronger muscles if their mothers had a higher level of vitamin D in their body during pregnancy, according to new research. Low vitamin D status has been linked to reduced muscle strength in adults and children, but little is known about how variation in a mother's status during pregnancy affects her child.

25 years of DNA on computers Posted: 03 Jan 2014 05:52 AM PST DNA carries out its activities "diluted" in the cell nucleus. In this state, it synthesizes proteins and, even though it looks like a messy tangle of thread, in actual fact its structure is governed by precise rules that are important for it to carry out its functions. Biologists have studied DNA by observing it experimentally with a variety of techniques, which have only recently been supplemented by research in silico, that is to say, the study of DNA by means of computer simulations.

Fear of childbirth predicts postpartum depression Posted: 03 Jan 2014 05:52 AM PST Expectant women with prenatally diagnosed fear of childbirth are at an increased risk of postpartum depression, according to a study of over 500,000 mothers in Finland. Women with a history of depression are at the highest risk of postpartum depression. The fact that fear of childbirth puts women without a history of depression at an approximately three times higher risk of postpartum depression is a new observation which may help health care professionals in recognising postpartum depression.

Shingles linked to increased risk of stroke in young adults Posted: 02 Jan 2014 01:56 PM PST Having shingles may increase the risk of having a stroke years later, according to research.

More funding for community health centers improves access to care Posted: 02 Jan 2014 12:23 PM PST Increased federal funding for community health centers has helped low-income adults get access to primary and dental care, according to a new study.

Doctors experienced with using EHRs say they add value for patients Posted: 02 Jan 2014 12:23 PM PST A majority of surveyed physicians said they were alerted to a potential medication error or critical lab value by an electronic health record, finds a new study.

Genetically identical bacteria can behave in radically different ways Posted: 02 Jan 2014 11:20 AM PST When a bacterial cell divides into two daughter cells there can be an uneven distribution of certain survival mechanisms. The resulting cells can behave differently from each other, depending on which parts they received in the split. This is another way that cells within a population can diversify and enhance the odds that some members of a population of bacteria can avoid threats, such as antibiotics.

Animal cells can communicate by reaching out, touching, study shows Posted: 02 Jan 2014 11:20 AM PST In a finding that directly contradicts the standard biological model of animal cell communication, scientists have discovered that typical cells in animals have the ability to transmit and receive biological signals by making physical contact with each other, even at long distance.

Molecule discovered that protects brain from cannabis intoxication Posted: 02 Jan 2014 11:20 AM PST Two INSERM research teams recently discovered that pregnenolone, a molecule produced by the brain, acts as a natural defense mechanism against the harmful effects of cannabis in animals. Pregnenolone prevents THC, the main active principle in cannabis, from fully activating its brain receptor, the CB1 receptor, that when overstimulated by THC causes the intoxicating effects of cannabis. By identifying this mechanism, the INSERM teams are already developing new approaches for the treatment of cannabis addiction.

Study: Having Medicaid increases emergency room visits Posted: 02 Jan 2014 11:20 AM PST Adults who are covered by Medicaid use emergency rooms 40 percent more than those in similar circumstances who do not have health insurance, according to a unique new study that sheds empirical light on the inner workings of health care in the US.

New MRI technique illuminates wrist in motion Posted: 02 Jan 2014 10:36 AM PST Radiologists, medical physicists and orthopaedic surgeons have found a way to create "movies" of the wrist in motion using a series of brief magnetic resonance imaging scans.

New cell mechanism discovery key to stopping breast cancer metastasis Posted: 02 Jan 2014 10:36 AM PST Researchers have discovered a cellular mechanism that drives the spread of breast cancer to other parts of the body (metastasis), as well as a therapy which blocks that mechanism.

The mouse that ROR’ed Posted: 02 Jan 2014 10:30 AM PST Researchers report that an oncogene dubbed ROR1, found on chronic lymphocytic leukemia (CLL) B cells but not normal adult tissues, acts as an accelerant when combined with another oncogene, resulting in a faster-developing, more aggressive form of CLL in mice.

Solution found to problem limiting development of human stem cell therapies Posted: 02 Jan 2014 10:30 AM PST Biologists have discovered an effective strategy that could prevent the human immune system from rejecting the grafts derived from human embryonic stem cells, a major problem now limiting the development of human stem cell therapies. Their discovery may also provide scientists with a better understanding of how tumors evade the human immune system when they spread throughout the body.

Study finds patients give 'broad endorsement' to stem cell research Posted: 02 Jan 2014 10:30 AM PST In an early indication of lay opinions on research with induced pluripotent stem cells (iPSCs), a new study by bioethicists indicates that despite some ethical concerns, patients give the research "broad endorsement".

More evidence suggests type 2 diabetes is inflammatory disease Posted: 02 Jan 2014 09:34 AM PST As people's waistlines increase, so does the incidence of type 2 diabetes. Now scientists have a better understanding of exactly what happens in the body that leads up to type 2 diabetes, and what likely causes some of the complications related to the disease. Specifically, scientists have found that in mice, macrophages, a specific type of immune cell, invade the diabetic pancreatic tissue during the early stages of the disease.

Scientists explain age-related obesity: Brown fat fails Posted: 02 Jan 2014 08:23 AM PST As most people resolve themselves to lose weight this New Year, here's why it seems to get easier and easier to pack on unwanted pounds: New research shows that as we age, the thermogenic activity of brown fat is reduced. Brown fat is a "good" fat located in the backs of our necks that helps burn "bad" white fat around our bellies.

Minimally invasive aortic valve replacement advantageous for some very elderly patients Posted: 02 Jan 2014 08:20 AM PST Transcatheter aortic valve implantation (TAVI) appears to be an effective alternative to surgical aortic valve replacement (AVR) for the treatment of aortic stenosis in very elderly patients, including those age 85 years and older

Decreasing need for blood transfusion during aortic valve replacement can help reduce complications, costs Posted: 02 Jan 2014 08:20 AM PST Incorporating a blood conservation strategy (BCS) during aortic valve replacement (AVR) can reduce the likelihood of transfusion-related complications, as well as reduce blood-product utilization.

High blood pressure potentially more dangerous for women than men Posted: 02 Jan 2014 08:20 AM PST Doctors may need to treat high blood pressure in women earlier and more aggressively than they do in men, according to scientists.

Pennies vs. Pounds: How 'supersizing' could actually lead to healthier choices Posted: 02 Jan 2014 08:20 AM PST New research has found that consumers may be just as willing to buy healthy food if they feel they're still getting a "supersize" deal.

Tripling tobacco taxes worldwide would avoid 200 million tobacco deaths Posted: 01 Jan 2014 02:58 PM PST Tripling taxes on cigarettes around the world would reduce the number of smokers by one-third and prevent 200 million premature deaths from lung cancer and other diseases this century, according to a review published today in the New England Journal of Medicine.

Insight into likelihood of developing retinal detachment following open eye injuries Posted: 01 Jan 2014 10:06 AM PST Researchers report on the first study in 35 years that reviews the circumstances around retinal detachment after open globe injuries (OGI) and describes a new tool that may help ophthalmologists predict which patients are at higher risk after open globe trauma so they can potentially prevent retinal detachment from happening or identify – and repair – it more quickly, thus saving vision.
