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

The body's immune response fights against infectious disease, and it safeguards against future infections through vaccination. However, if the immune response dysfunctions and attacks the body itself, it can cause autoimmune disease. Thus, a healthy immune response balances an instant readiness to combat infecting viruses or bacteria, while maintaining benign surveillance of the body's own tissues.

Over one-fifth of injured U.S. adult cyclists, mostly men, not wearing a helmet

Men and ethnic minorities are less likely to wear cycle helmets and more likely to suffer from head and neck injuries in accidents, according to new research published in Brain Injury.

Few people with peanut allergy tolerate peanut after stopping oral immunotherapy

Allergy to peanut, which is often severe, is one of the most common food allergies in the United States. Although previous studies have shown that peanut oral immunotherapy (OIT)—ingesting small, controlled amounts of peanut protein—can desensitize adults and children and prevent life-threatening allergic reactions, the optimal duration and dose is unknown. In a study that followed participants after OIT successfully desensitized them to peanut, discontinuing OIT or continuing OIT at a reduced dose led to a decline in its protective effects. The study, published online today in The Lancet, also found that several blood tests administered before OIT could predict the success of therapy. The Phase 2 study was supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH, and may inform who may benefit from peanut OIT and what changes in this experimental treatment should be implemented.

Addressing serious illness with a serious question to clinicians

Three-quarters of older adults with a serious illness visit the emergency department during the last six months of their lives. Many will be admitted to the hospital. Some will never leave. But only a minority of patients have a conversation with their physician about preferences for end-of-life care before it is too late in their disease course for their wishes to be expressed. Identifying patients at greatest risk of near-term death early enough to engage in these conversations could both improve patients' experiences and drive down health care costs.

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

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. Led by researchers at Boston Medical Center's Grayken Center for Addiction, 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. These results, published in Drug and Alcohol Dependence, provide a roadmap to better reach these individuals at high risk of overdose and provide treatment and harm reduction services in order to reduce the number of overdose deaths.

Predicting risk of heart failure for diabetes patients with help from machine learning

Heart failure is an important potential complication of type 2 diabetes that occurs frequently and can lead to death or disability. Earlier this month, late-breaking trial results revealed that a new class of medications known as SGLT2 inhibitors may be helpful for patients with heart failure. These therapies may also be used in patients with diabetes to prevent heart failure from occurring in the first place. However, a way of accurately identifying which diabetes patients are most at risk for heart failure remains elusive. A new study led by investigators from Brigham and Women's Hospital and UT Southwestern Medical Center unveils a new, machine-learning derived model that can predict, with a high degree of accuracy, future heart failure among patients with diabetes. The team's findings are presented at the Heart Failure Society of America Annual Scientific Meeting in Philadelphia and simultaneously published in Diabetes Care.

'Yank': A new term in biophysics

Biologists and biomedical engineers are proposing to define the term "yank" for changes in force over time, something that our muscles and nerves can feel and respond to.

Mother cells as organelle donors

Microbiologists at LMU and UoG have discovered a recycling process in the eukaryotic parasite Toxoplasma gondii that plays a vital role in the organism's unusual mode of reproduction.

Extinction of Icelandic walrus coincides with Norse settlement

An international collaboration of scientists in Iceland, Denmark and the Netherlands has for the first time used ancient DNA analyses and C14-dating to demonstrate the past existence of a unique population of Icelandic walrus that went extinct shortly after Norse settlement some 1100 years ago. Walrus hunting and ivory trade was probably the principal cause of extinction, being one of the earliest examples of commercially driven overexploitation of marine resources.

Male Trinidad guppies find food thanks to females

For male Trinidad Guppies applies: if you are hungry, seek female company. A recent study led by scientists of the the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Leibniz Institute for Zoo and Wildlife Research (IZW) together with other research institutions provides evidence that male guppy fish in the presence of females more often ended up at novel food patches. In contrast, female food discovery was independent of male presence.

Researchers find waterhemp has evolved resistance to four herbicide sites of action

A research study featured in the journal Weed Science provides worrisome new details about the evolution of herbicide resistance in waterhemp—an annual weed that represents a significant threat to Midwest corn and soybean crops.

Salmon Tales: Sex, myth and molecular genetics of an iconic fish

A sockeye salmon's life ends right back where it began, culminating in an anadromous drama of sex, decay and sacrifice.

Breeding single-sex animal populations could help prevent disease and poverty

The creation of all-male or all-female groups of animals, known as monosex populations, has become a potentially useful approach in aquaculture and livestock rearing.
