Opioid use disorder affects about 2 million Americans each year and is the No. 1 cause of accidental death. Between 50 to 90 percent of individuals with this disorder were exposed to a prescription opioid first. Opioid use disorder is likely underdiagnosed within the healthcare system setting, which may be due in part to the reticence of practitioners who lack the specialized training in addiction medicine.

A gut hormone, ghrelin, is a key regulator of new nerve cells in the adult brain, a Swansea-led research team has discovered. It could help pave the way for new drugs to treat dementia in patients with Parkinson's Disease.

Blood-borne factors such as hormones regulate the process of brain cell formation - known as neurogenesis - and cognition in adult mammals.

Marine fish species are migratory in nature and not respectful of human-made territorial boundaries, which represents a challenge for fisheries management as policies tend to focus at the national level. With an average catch of 48 million tonnes per year, and USD $77 billion in annual fishing revenue, these species support critical fisheries, and require international cooperation to manage, according to UBC research.

In school bullying, there are people who are chronic victims. The acts of aggression that they experience are not limited to a particular moment or period of time, but rather part of a sustained process over a long period of time. These aggressions have much more serious consequences: chronic victims show higher levels of stress and personality issues that do not appear in students who have no connection to school bullying or those who have experienced it for shorter periods of time.

(Vienna, 21 October 2020) A recent study conducted by a research team led by Florian Kiefer from MedUni Vienna's Division of Endocrinology and Metabolism shows that cold ambient temperatures increase vitamin A levels in humans and mice. This helps convert "bad" white adipose tissue into "good" brown adipose tissue which stimulates fat burning and heat generation. This "fat transformation" is usually accompanied by enhanced energy consumption and is therefore considered a promising approach for the development of novel obesity therapeutics.

Volunteers from the Catholic Church in Brazil helped to mitigate the impact of COVID-19 among the elderly, a new study shows.

Peter Kevern, Professor Values in Health and Social Care at Staffordshire University, partnered with The Pontifical Catholic University of São Paulo to carry out the study which looked at the contribution of the Pastoral da Pessoa Idosa (PPI) programme in Brazil.

A new study led by scientists at IUPUI and Indiana University Bloomington is the first to describe a biochemical mechanism that increases the activity of a molecule whose presence is observed in many types of cancer.

The newly published thesis research of University of Guam Master of Environmental Science graduate Benjamin Deloso now adds to the body of knowledge about asexual propagation of the most endangered plant group in the world, cycads. His work was part of a set of UOG studies, all focused on improving the asexual propagation of cycads, published in the September 2020 issue of HortScience, one of the oldest horticultural journals in the United States.

We employ our cognitive skills daily to assimilate and process information. A new empirical study shows that we do better at this task than those born a century ago. But cognitive capacity still begins to stagnate at around the age of 35.

TAMPA, Fla. -- Prostate cancer is the most common type of cancer among American men after skin cancer, but the disease does not affect all races equally. African American men are nearly two times more likely to develop prostate cancer, and more often have an aggressive form of the disease that grows and spreads quickly. They are also two times more likely to die from prostate cancer compared to white men. While the health care community is aware of this disparity, little is known about why prostate cancer affects African American men differently.

BUFFALO, N.Y. -- Chemicals that haven't been manufactured in the U.S. for years or even decades are still turning up in the bodies of migratory terns in the Great Lakes region, a new study finds.

The research focused on three types of compounds: polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and the breakdown products, called metabolites, of dichlorodiphenyltrichloroethane (DDT).

During cell division specific target proteins have to be turned over in a precisely regulated manner. To this end specialized enzymes label the target proteins with signaling molecules. However, the enzymes involved in this process can also label themselves, thus initiating their own degradation. In a multidisciplinary approach, the researchers identified a mechanism of how enzymes can protect themselves from such self-destruction and maintain sufficient concentrations in the cell. These results have been published in the latest issue of Science Signaling.

According to the Mayo Clinic, about 15% of couples are infertile, and male infertility plays a role in over one-third of these cases. Often, problems with sperm development are to blame. Now, researchers reporting in ACS Nano have found a way to deliver a protein important for sperm cell production directly to mouse testicles, where it restored normal sperm development and allowed previously infertile mice to father pups.

Wrong-site surgery, medication errors, and fires in operating rooms can be devastating for patients, providers, hospitals, and insurance companies alike. In risk management, these are referred to as sentinel adverse events. Determining the true causes of these events can help hospitals improve their processes, leading to large impacts on costs and outcomes of care.
