Chronic fatigue syndrome flare-ups caused by straining muscles and nerves Posted: 18 Jul 2016 04:41 PM PDT Mild to moderate muscle and nerve strain provokes symptom flares in individuals with chronic fatigue syndrome.

Genetic drivers of immune response to cancer discovered through 'big data' analysis Posted: 18 Jul 2016 01:13 PM PDT Scientists have identified over 100 new genetic regions that affect the immune response to cancer. The findings could inform the development of future immunotherapies -- treatments that enhance the immune system's ability to kill tumors.

Malaria: A genetically attenuated parasite induces an immune response Posted: 18 Jul 2016 10:33 AM PDT With nearly 3.2 billion people currently at risk of contracting malaria, scientists have experimentally developed a live, genetically attenuated vaccine for Plasmodium, the parasite responsible for the disease. By identifying and deleting one of the parasite's genes, the scientists enabled it to induce an effective, long-lasting immune response in a mouse model. These findings were published in the Journal of Experimental Medicine on July 18, 2016.

New link between periodontal and cerebrovascular diseases Posted: 18 Jul 2016 10:33 AM PDT A new study has revealed a relationship between chronic periodontitis and lacunar infarct, two common diseases in the elderly. Chronic periodontitis is an inflammatory disease of the gums, whereas lacunar infarct is a type of cerebral small vessel disease that can lead to a stroke.

Soft drink, soft price: Soda prices found to be significantly low Posted: 18 Jul 2016 10:32 AM PDT Researchers found a huge disparity between the price of soda, which is linked to the prevalence of health issues like diabetes, and milk -- a difference in price that could be narrowed by taxes like the one on sugary drinks recently approved in Philadelphia.

Modified rye bread helps patients with irritable bowel syndrome Posted: 18 Jul 2016 10:32 AM PDT Patients with irritable bowel syndrome (IBS) are often concerned that certain foods may trigger or worsen their symptoms, which can include abdominal pain, diarrhea, or constipation. In a new study, patients who ate rye bread that was low in so-called 'FODMAPs' (fermentable oligo- di- and mono-saccharides and polyols) experienced milder IBS symptoms than patients who ate normal rye bread.

Scientists discover how proteins in the brain build-up rapidly in Alzheimer's Posted: 18 Jul 2016 10:30 AM PDT Researchers have identified -- and shown that it may be possible to control -- the mechanism that leads to the rapid build-up of the disease-causing 'plaques' that are characteristic of Alzheimer's disease.

How the body disposes of red blood cells, recycles iron Posted: 18 Jul 2016 10:26 AM PDT What happens when red blood cells become damaged or reach the end of their normal life span, and how is the iron required for carrying oxygen recycled? A new study contradicts previous thinking about where and how worn-out red blood cells are disposed of and their iron retained for use in new cells.

Scientists determine structure of enzyme linked with key cell-signaling protein Posted: 18 Jul 2016 10:26 AM PDT Scientists have captured atomic level snapshots showing how one key enzyme modifies a protein involved in turning genes on or off inside cells. Understanding this process helps explain how complex organisms can arise from a finite number of genes. The research also identifies links between defects in this particular enzyme and certain cancers, potentially pointing to new drug targets.

Helping doctors transform their practices into patient-centered models of health care Posted: 18 Jul 2016 10:26 AM PDT The article demonstrates the effectiveness of teaching practice facilitators how to use cognitive task analysis to help them guide doctors's office staff in changing to a patient-centered model.

Infantile memory study points to critical periods in early-life learning for brain development Posted: 18 Jul 2016 08:19 AM PDT A new study on infantile memory formation in rats points to the importance of critical periods in early-life learning on functional development of the brain. The research reveals the significance of learning experiences over the first two to four years of human life.

Fracking industry wells associated with increased risk of asthma attacks Posted: 18 Jul 2016 08:19 AM PDT People with asthma who live near bigger or larger numbers of active unconventional natural gas wells operated by the fracking industry in Pennsylvania are 1.5 to four times likelier to have asthma attacks than those who live farther away, new research suggests.

Rise in avoidable diabetes hospital visits Posted: 18 Jul 2016 08:16 AM PDT Hospital admissions for a short-term and avoidable complication of diabetes have risen by 39 per cent in the last ten years, a new analysis has concluded.

Mental, physical exercises produce distinct brain benefits Posted: 18 Jul 2016 08:09 AM PDT Cognitive brain training improves executive function whereas aerobic activity improves memory, according to new research.

No blood vessels without cloche Posted: 18 Jul 2016 08:09 AM PDT After 20 years of searching, scientists discover the mystic gene controlling vessel and blood cell growth in the embryo.

Grandpa's obesity affects the health of his grandchildren: Mouse study Posted: 18 Jul 2016 08:09 AM PDT With a major global issue of obesity, researchers are warning of the harmful legacy that parental obesity can have on future generations. It follows a vital breakthrough in obesity research, which shows a father's metabolic health can be passed from generation to generation, affecting not only his children but importantly his grandchildren.

Quality of care in VA health care system compares well to other settings Posted: 18 Jul 2016 08:09 AM PDT The quality of health care provided to US military veterans in Veterans Affairs (VA) facilities compares favorably with the treatment and services delivered outside the VA. In fact, VA facilities perform better in some cases when it comes to the safety and effectiveness of the treatment provided.

Malnutrition, shaping up to be a first world problem Posted: 18 Jul 2016 06:34 AM PDT Researchers have discovered that a bad diet has consequences on your immune system even before you notice an increase in body weight. Mice were fed a Western-style high fat diet for nine weeks. They structure and function of their immune cells was found to have been altered in the absence of weight gain.

Many elderly people are receiving and using prescription medications inappropriately Posted: 18 Jul 2016 06:34 AM PDT A new study indicates that the majority of community-dwelling elderly adults are taking prescription medications inappropriately. The study also found a link between underuse -- not taking essential medications -- and an increased risk of dying or needing to be hospitalized.

Novel biomarkers can help detect illegal blood doping in athletes Posted: 18 Jul 2016 06:34 AM PDT Increasing oxygen delivery to muscles can help athletes perform better and give them the edge needed to win elite competitions. This can be done through illegal 'blood doping': undergoing a blood transfusion for extra red blood cells to boosts oxygen levels. While some transfusions are identifiable with current testing methods, autologous blood transfusion (ABT) is not. A new report looks at novel biomarkers to identify potential new testing protocols for ABT.

Genomic region associated with autism plays role in specific cognitive functions Posted: 18 Jul 2016 06:34 AM PDT A new study reports that variations in 16p11.2, a region of the genome associated with risk of autism spectrum disorder (ASD), have distinct effects on cognition. The findings highlight the diversity of people with ASD.

HIV therapy for breastfeeding mothers can virtually eliminate transmission to babies Posted: 18 Jul 2016 06:34 AM PDT For HIV-infected mothers whose immune system is in good health, taking a three-drug antiretroviral regimen during breastfeeding essentially eliminates HIV transmission by breast milk to their infants, according to results from a large clinical trial.

HIV treatment keeps uninfected partner from contracting the virus Posted: 18 Jul 2016 06:33 AM PDT Anti-HIV medications suppress the viral load of people living with HIV and provide durable protection against heterosexual transmission found. Researchers found a 93 percent reduction of HIV transmission when the HIV-infected person started antiretroviral therapy or ART at a higher CD4 cell count.

New evidence on why young women in South Africa are at high risk of HIV infection Posted: 18 Jul 2016 06:33 AM PDT New evidence is shedding new light on why young women in South Africa have high rates of HIV infection.

Used consistently, monthly vaginal ring may be highly effective against HIV in women, study suggests Posted: 18 Jul 2016 06:31 AM PDT When used consistently for a month at a time, a vaginal ring containing the antiretroviral drug, dapivirine, provides significant protection against HIV, suggest new results. Among women who appeared to use the ring most regularly, HIV risk was cut by more than half in all analyses, and in some, by 75 percent or more.

New genetic cause of Coats plus syndrome Posted: 18 Jul 2016 06:31 AM PDT A team of Israeli researchers has discovered that mutations in STN1, a gene that helps maintain the ends of chromosomes, cause the rare, inherited disorder Coats plus syndrome.
