16.09.2019Human hearts evolved for endurance

Major physical changes occurred in the human heart as people shifted from hunting and foraging to farming and modern life. As a result, human hearts are now less 'ape-like' and better suited to endurance types of activity.

16.09.2019Defective cilia linked to heart valve birth defects

Bicuspid aortic valve (BAV), the most common heart valve birth defect, is associated with genetic variation in human primary cilia during heart valve development, report researchers. Crucial to cilia development is the exocyst, which shuttles cilia cargo to the cell membrane. Disrupting the exocyst impaired ciliogenesis and caused a spectrum of cardiac defects in zebrafish and BAV in mice.

New research shows just how important positive childhood experiences are for long-term health, especially for those who experience significant adversity as a child. Studies over the past 20 years have found a correlation between adverse childhood events (such as death or divorce) and worse health outcomes later in life. A new study discovers that positive childhood experiences, like having good neighbors, or a teacher you trust, have the potential to negate harmful health effects caused by adverse childhood experiences.

16.09.2019Anemia may contribute to the spread of dengue fever

Mosquitoes are more likely to acquire the dengue virus when they feed on blood with low levels of iron, researchers report. Supplementing people's diets with iron in places where both iron deficiency anemia and dengue fever are a problem could potentially limit transmission of the disease, but there are risks.

Valley fever is endemic to hot and dry regions like the southwestern United States and California's San Joaquin Valley, but a new study predicts climate change will cause the fungal infection's range to more than double in size this century, reaching previously unaffected areas across the western U.S.

16.09.2019Too much of a good thing: Overactive immune cells trigger inflammation

Scientists describe a previously unknown disorder of the immune system: in a distinct subset of immune cells from patients with primary immunodeficiency, cellular respiration is significantly increased. This cellular metabolic overactivity leads to inflammation.

16.09.2019Lack of sleep affects fat metabolism

A restricted-sleep schedule built to resemble an American work week made study participants feel less full after a fatty meal and altered their lipid metabolism. One night of recovery sleep helped, but didn't completely erase the effects of sleep restriction.

These findings pave the way for new, effective treatment approaches for AD.

16.09.2019Sweet success of parasite survival could also be its downfall

Scientists have discovered how a parasite responsible for spreading a serious tropical disease protects itself from starvation once inside its human host. The findings provide a new understanding of the metabolism of the Leishmania parasite and this new knowledge could potentially be used in its eradication.

16.09.2019Violent video games blamed more often for school shootings by white perpetrators

People are more likely to blame violent video games as a cause of school shootings by white perpetrators than by African-American perpetrators, possibly because of racial stereotypes that associate minorities with violent crime, according to new research.

16.09.2019Subgroup of colorectal cancer patients ID'd: Do poorly, could benefit from immunotherapy

While the medical community agrees immune cells inside a tumor leads to improved health outcome, for a subset of colorectal cancer patients, having too much of a good thing is a strong predictor of disease recurrence and reduced chances of survival. Scientists identify patients who could benefit from immunotherapy. This is the first report of immune infiltrated tumors with poor health outcomes and is counter to the standard belief in the field.

16.09.2019Just bad luck? Cancer patients nominate 'fate' as third most likely cause

What role does fate play when it comes to the 145,000 people diagnosed with cancer each year in Australia and 125,000 people in Vietnam?

13.09.2019How IL-6 allows the immune response to develop for a key cell, the T follicular helper

A preclinical study shows how the interplay of two interleukin signaling proteins, IL-6 and IL-2, affects the development of T follicular helper cells and germinal centers. This interplay may either maintain or disrupt the balancing act of the immune system between attacking infections and benign surveillance of the body's own cells. Thus, the research may help guide future disease treatment for autoimmune diseases like lupus.

13.09.2019Therapeutic strategies for pregnant women with lupus

A highly gender-biased disease, lupus afflicts females some nine times more than males. Because of the disease's unpredictable turns and debilitating flares -- the risks of which are elevated in postpartum women -- females with the disease are often advised to avoid pregnancy altogether.

13.09.2019Focus points to reduce opioid overdose deaths identified

A new study identifies specific locations where medication and harm reduction services for people with opioid use disorder should be available in order to have the greatest impact on reducing opioid overdose deaths. The data show that more than half of those who died of an opioid overdose in Massachusetts encountered the health care, public health and/or criminal justice systems within the 12 months prior to their fatal overdose.

13.09.2019Few people with peanut allergy tolerate peanut after stopping oral immunotherapy

Studies have shown that peanut oral immunotherapy (OIT) -- ingesting small, controlled amounts of peanut protein -- can desensitize adults and children and prevent allergic reactions, but the optimal duration and dose is unknown. In a study that followed participants after successful OIT, discontinuing OIT or continuing OIT at a reduced dose led to a decline in its protective effects. The study also found that blood tests administered before OIT could predict the success of therapy.

13.09.2019How new loops in DNA packaging help us make diverse antibodies

It's long been known that our immune cells mix and match bits of genetic code to make new kinds of antibodies to fight newly encountered threats. But how these different gene segments come together has been a mystery. A study provides the answer, showing how the classic process of V(D)J recombination makes use of chromatin looping to gather the segments to be spliced.

13.09.2019Speeding up the drug discovery process to help patients

An international research team is perfecting a method to predict the potential clinical implications of new drugs before clinical trials even start.

13.09.2019'Communities that Care' prevention system helps to protect youth

13.09.2019Slower growth in working memory linked to teen driving crashes

Research into why adolescent drivers are involved in motor vehicle crashes, the leading cause of injury and death among 16- to 19-year-olds in the United States, has often focused on driving experience and skills. But a new study suggests that development of the adolescent brain -- in particular, working memory -- may play a critical role in whether a teenager is more likely to crash.

13.09.2019Addressing serious illness with a serious question to clinicians

A question: 'Would you be surprised if this patient died in the next month?' -- posed to elicit a clinician's overall impression of a patient -- produced a strong correlation. If a clinician answered that they would not be surprised, the patient was twice as likely to die in the next month.

13.09.2019High social support associated with less violence among male teens in urban neighborhoods

Researchers find that the presence of adult social support is linked to less violence among at-risk teen boys.

13.09.2019Tiny bubbles in our body could fight cancer better than chemo

Healthy cells in our body release nano-sized bubbles that transfer genetic material such as DNA and RNA to other cells. It's your DNA that stores the important information necessary for RNA to produce proteins and make sure they act accordingly. These bubbly extracellular vesicles could become mini treatment transporters, carrying a combination of therapeutic drugs and genes that target cancer cells and kill them, according to new research from Michigan State University and Stanford University.
