Soluble corn fiber can help young women build bone, and older women preserve bone Posted: 22 Aug 2016 12:26 PM PDT Supplementing with soluble corn fiber at two critical times in a woman's life -- adolescence and post-menopause -- can help build and retain calcium in bone, according to new research.

How melanoma spreads to other organs in the body Posted: 22 Aug 2016 11:05 AM PDT In a landmark discovery, researchers have unraveled the metastatic mechanism of melanoma, the most aggressive of all skin cancers. Their work may lead to a cure for the deadly disease.

How cell nuclei squeeze into tight spaces Posted: 22 Aug 2016 11:05 AM PDT As cells move throughout our bodies, they often have to squeeze through tight nooks and crannies in their environment, reliably springing back to their original shape. The structures involved in this process are still a mystery, but now a research team reports one protein responsible for giving a cell's nucleus its durable, deformable nature. These results, the authors say, may explain the invasiveness of certain cancer cells.

Monkeys protect against lethal Ebola Sudan infection four days after infection Posted: 22 Aug 2016 09:55 AM PDT Researchers have protected nonhuman primates against Ebola Sudan four days following exposure to the virus.

New types of African Salmonella associated with lethal infection Posted: 22 Aug 2016 09:54 AM PDT The first global-scale genetic study of Salmonella Enteritidis bacteria, which is a major cause of blood poisoning and death in Africa and food poisoning in the Western World, has discovered that there are in fact three separate types. Scientists found two novel African types, which looked the same, but were genetically different from the Western type.

Esophageal cancers driven by 'marginal gain' rather than speed Posted: 22 Aug 2016 09:54 AM PDT Scientists have shown that unexpectedly, esophageal cancer cells do not divide faster than their normal neighbors. But unlike normal cells, the tumor cells produce slightly more dividing daughter cells than non-dividing ones, forming a tumor. The study could lead to the development of new treatments for cancers that do not respond to current therapies which target fast-growing cells.

Transcription factor Foxn1 and preserving immune function in later life Posted: 22 Aug 2016 09:49 AM PDT Researchers use new experimental models and analytical tools to investigate genes regulated by Foxn1, becoming the first to identify the DNA sequence bound by the transcription factor. Among the hundreds of genes whose expression is regulated by Foxn1 are genes essential to attract precursor cells in the blood to the thymus, that commit precursor cells to become T cells, and that provide the molecular machinery which allows T cell selection to best serve an individual.

Rx associated with fracture risk infrequently reduced after fracture occurrence Posted: 22 Aug 2016 09:49 AM PDT Is the occurrence of a fragility fracture -- where Medicare beneficiaries broke a hip, wrist or shoulder -- a missed opportunity to reduce exposure to prescription drugs associated with fracture risk?

Antibiotic treatment increased risk for type 1 diabetes in animal study Posted: 22 Aug 2016 09:49 AM PDT In doses equivalent to those used regularly in human children, antibiotics changed the mix of gut microbes in young mice to dramatically increase their risk for type 1 diabetes.

Hope for reversing stroke-induced long-term disability Posted: 22 Aug 2016 09:49 AM PDT Permanent brain damage from a stroke may be reversible thanks to a developing therapeutic technique, a study has found. The novel approach combines transplanted human stem cells with a special protein that the US Food and Drug Administration already approved for clinical studies in new stroke patients. The researchers say they are the first to use 3K3A-APC to produce neurons from human stem cells grafted into the stroke-damaged mouse brain.

Two key proteins preserve vital genetic information Posted: 22 Aug 2016 09:49 AM PDT New research demonstrates how two key proteins mediate the organization of chromosomes and our genome, shedding light on one of the key genetic processes for every person. With this key basic information in hand, scientists may now be able to pinpoint the origins of cancer due to genetic mutations.

New care plan improves Crohn’s disease complication outcomes Posted: 22 Aug 2016 08:21 AM PDT The first published medical and surgical approach care plan for managing septic perianal Crohn's disease, a serious complication that occurs in around 40 percent of Crohn's disease patients has been developed. The plan and its results took more than a decade to develop and are based on patient outcomes.

Fussy infants find food more rewarding, putting them at higher risk for obesity Posted: 22 Aug 2016 08:19 AM PDT Babies that seem to get upset more easily and take longer to calm down may be at higher risk for obesity while babies that exhibit more 'cuddliness' and calm down easily are less likely at risk, according to a new study.

Many stroke patients experience delays in seeking and receiving care Posted: 22 Aug 2016 08:18 AM PDT A new study reveals that many patients are not aware that they are having a stroke when they are experiencing symptoms.

Tunneling nanotubes between neurons enable the spread of Parkinson's disease via lysosomes Posted: 22 Aug 2016 08:18 AM PDT Scientists have demonstrated the role of lysosomal vesicles in transporting alpha-synuclein aggregates, responsible for Parkinson's and other neurodegenerative diseases, between neurons. These proteins move from one neuron to the next in lysosomal vesicles which travel along the 'tunneling nanotubes' between cells.

Answering the call for quality colorectal cancer patient info Posted: 22 Aug 2016 08:18 AM PDT Patients depend on the Internet for health information, but when it comes to colorectal cancer, currently available resources are not meeting their needs.

Sick animals limit disease transmission by isolating themselves from their peers Posted: 22 Aug 2016 07:07 AM PDT Sick wild house mice spend time away from their social groups, leading to a decrease in their potential for disease transmission according to a new study. The results can improve models focused on predicting the spread of infectious diseases like influenza or Ebola in humans.

Full adherence to guideline-recommend therapies associated with lower rate of MACE Posted: 22 Aug 2016 07:07 AM PDT MINERVA results demonstrate full adherence to guideline-recommended therapies associated with lower rate of a second major cardiovascular event and cost savings.

Is it your second cousin? Cotton swabs may tell you Posted: 22 Aug 2016 07:06 AM PDT With a new technique, a simple swab sample can accurately confirm relatedness between two individuals as distant as second cousins. With more DNA datasets at hand, the method could be utilized to identify disaster victims in mass floods and tornadoes that destroy entire communities.

Urban water pumping raises arsenic risk in Southeast Asia Posted: 22 Aug 2016 07:06 AM PDT Large-scale groundwater pumping is opening doors for dangerously high levels of arsenic to enter some of Southeast Asia's aquifers, with water now seeping in through riverbeds with arsenic concentrations more than 100 times the limits of safety, according to a new study.

Scientists challenge recommendation that men with more muscle need more protein Posted: 22 Aug 2016 05:36 AM PDT Sports nutrition recommendations may undergo a significant shift after new research has found individuals with more muscle mass do not need more protein after resistance exercise.

New global migration mapping to help fight against infectious diseases Posted: 22 Aug 2016 05:36 AM PDT Geographers have completed a large scale data and mapping project to track the flow of internal human migration in low and middle income countries. Researchers have, for the first time, mapped estimated internal migration in countries across three continents; Africa, Asia and Latin America and the Caribbean.

Elongation by contraction: Pulling forces drive changes in cell shape Posted: 22 Aug 2016 05:36 AM PDT

Lousy jobs hurt your health by the time you're in your 40s Posted: 22 Aug 2016 05:34 AM PDT Job satisfaction in your late 20s and 30s has a link to overall health in your early 40s, according to a new nationwide study.

One approach can prevent teen obesity, eating disorders, new guidelines say Posted: 22 Aug 2016 05:34 AM PDT A single approach can prevent both obesity and eating disorders in teenagers, according to new guidelines.

Socioeconomic factors -- not race or ethnicity -- influence survival of younger patients with multiple myeloma Posted: 22 Aug 2016 05:34 AM PDT Advances in the treatment of multiple myeloma, a cancer that forms in a type of white blood cell, have led to improved survival predominantly among young and white patients, with less of an increase in survival observed in patients of other ethnicities. A new study indicates that this gap is mostly due to socioeconomic differences between whites and ethnic minorities, not race itself.

Health-care consumer advocates chose moderation, won some successes in Medicaid debate Posted: 22 Aug 2016 05:32 AM PDT Even though most consumer advocate groups were likely opposed to Medicaid reform, advocates tended to frame the problem of reform in terms of symptoms, such as accountability, transparency and troubles that providers and consumers would experience instead of a wholesale opposition to privatizing the system, study finds.

After the heart attack: Injectable gels could prevent future heart failure Posted: 22 Aug 2016 05:32 AM PDT During a heart attack, clots or narrowed arteries block blood flow, harming or killing cells in the heart. But damage doesn't end after the crushing pain subsides. Instead, the heart's walls thin out, the organ becomes enlarged, and scar tissue forms. These changes can cause heart failure. Scientists now report they have developed injectable gels to prevent this damage.

Simple new test could improve diagnosis of tuberculosis in developing nations Posted: 22 Aug 2016 05:32 AM PDT The current test used in developing nations to diagnose tuberculosis is error-prone, complicated and slow. Furthermore, patients in these resource-limited areas can't easily travel back to a clinic at a later date to get their results. Chemists have now developed a simpler, faster and more accurate test.

New device could help improve taste of foods low in fat, sugar and salt Posted: 22 Aug 2016 05:32 AM PDT Scientists may be closing in on a way to let consumers savor the sweet taste of cake, cookies and other delights without the sugar rush. They have isolated several natural aromatic molecules that could be used to trick our brains into believing that desserts and other foods contain more fat, sugar or salt than they actually do.

Nanoparticles that speed blood clotting may someday save lives Posted: 22 Aug 2016 05:32 AM PDT Whether severe trauma occurs on the battlefield or the highway, saving lives often comes down to stopping the bleeding as quickly as possible. Now, researchers have developed nanoparticles that congregate wherever injury occurs in the body to help it form blood clots, and they've validated these particles in test tubes and in vivo.

Watching thoughts -- and addiction -- form in the brain Posted: 22 Aug 2016 05:32 AM PDT In a classic experiment, Ivan Pavlov conditioned dogs to salivate at the ringing of a bell. Now, scientists can see what happens in the brains of live animals during this experiment with a new technique. The approach could lead to a greater understanding of how we learn and develop addictions.
