People with fibromyalgia are substituting CBD for opioids to manage pain

Fibromyalgia is one of many chronic pain conditions that remains stubbornly difficult to treat. As the ravages of the opioid epidemic lead many to avoid these powerful painkillers, a significant number of people with fibromyalgia are finding an effective replacement in CBD-containing products, finds a new Michigan Medicine study. CBD, short for cannabidiol, is the second most common cannabinoid in the cannabis plant, and has been marketed for everything from mood stabilization to pain relief, without the intoxicating effects produced by the most common cannabinoid, THC. THC, which stands for ...

Membrane proteins of bacteria and humans show surprising similarities

The cells of simple organisms, such as bacteria, as well as human cells are surrounded by a membrane, which fulfills various tasks including protecting the cell from stress. In a joint project, teams from Johannes Gutenberg University Mainz (JGU) and Forschungszentrum Jülich, with participation of Heinrich Heine University Düsseldorf (HHU), have now discovered that a membrane protein found in bacteria has a similar structure and function as a group of proteins that are responsible for remodeling and rebuilding the cell membrane in humans. No connection between the two protein groups was known before. The team's research work has been published recently in the renowned journal Cell. PspA plays a key role in bacterial stress response The phage shock protein ...

Immunotherapy may be effective for subset of prostate cancer

Boston - In recent years, cancer immunotherapy has been effective in treating patients with immunogenic, or so-called "hot" tumors with increased levels of inflammation and the presence of immune cells in and around the tumors. Prostate cancer, however, is considered a "cold" tumor, with few immune cells recognizing and infiltrating prostate malignancies. Accordingly, prostate cancer has been found to respond poorly to the class of immunotherapies known as immune checkpoint inhibitors. In previous work, a team led by medical oncologists at Beth Israel Deaconess Medical Center (BIDMC) identified a subset of prostate cancers that exhibited ...

Versatile, fast and reliable SARS-CoV-2 antibody assay

During the continued progression of the Corona pandemic, rapid, inexpensive, and reliable tests will become increasingly important to determine whether people have the associated antibodies - either through infection or vaccination. Researchers at the Technical University of Munich (TUM) have now developed such a rapid antibody test. It provides the result in only eight minutes; the aim is to further reduce the process time to four minutes. There are currently more than 20 different test procedures available for determining whether a person has antibodies against the new Corona virus. The waiting times for the results range between ten minutes and two and a half hours. Matrix effects reduce the sensitivity of many of the methods. The more sensitive assays require numerous steps, ...

Are zebra mussels eating or helping toxic algae?

While invasive zebra mussels consume small plant-like organisms called phytoplankton, Michigan State University researchers discovered during a long-term study that zebra mussels can actually increase Microcystis, a type of phytoplankton known as "blue-green algae" or cyanobacteria, that forms harmful floating blooms. "Microcystis literally means small cell, but numerous cells cluster together in colonies that can float to the surface to form scums," said Orlando Sarnelle, a professor emeritus with the Department of Fisheries and Wildlife within the College of Agriculture and Natural Resources. "It is one of the most common causes of nuisance algal blooms in nutrient-enriched waters, including Lake ...

The job you want vs. the job you get

When it comes to career aspirations for teenagers, a University of Houston psychology researcher believes it's best to shoot for the moon, so you can at least land in the stars. The truth is the moon may sometimes be unreachable. In the Journal of Career Assessment, Kevin Hoff, assistant professor of psychology, reports the existence of important discrepancies between young people's dream jobs and employment realities. "Almost 50% of adolescents aspired to investigative or artistic careers, which together account for only 8% of the U.S. labor market," reports Hoff, whose research examined the career aspirations of 3,367 adolescents (age 13-18 years) from 42 U.S. states. Investigative jobs include those in the field of science and research. Hoff's team ...

Embryologists reveal a secret of a worm with regeneration super abilities

This worm that lives in the White Sea is able to restore lost body segments. However, it turned out that suppression of FGF protein activity disturbs this ability. Similar proteins are found in humans. This discovery may lead to developing methods of fast wound healing. The research findings are published in the journal Genes as part of the project supported by the Russian Science Foundation. Fibroblast growth factors (FGF) are proteins that play an important role in wound healing and tissue growth. When the need for regeneration of damaged body parts occur, FGFs are produced by epidermis, nervous tissue, macrophages and fibroblasts, which are the main cells of connective tissue. As a result, ...

Adolescent marijuana, alcohol use held steady during COVID-19 pandemic

Adolescent marijuana use and binge drinking did not significantly change during the COVID-19 pandemic, despite record decreases in the substances' perceived availability, according to a survey of 12th graders in the United States. The study's findings, which appeared online on June 24, 2021, in Drug and Alcohol Dependence, challenge the idea that reducing adolescent use of drugs can be achieved solely by limiting their supply. The work was led by researchers at the University of Michigan, Ann Arbor, and funded by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health. In contrast to consistent rates of marijuana and alcohol use, nicotine vaping in high school seniors ...

Cosmic hand hitting a wall

Motions of a remarkable cosmic structure have been measured for the first time, using NASA's Chandra X-ray Observatory. The blast wave and debris from an exploded star are seen moving away from the explosion site and colliding with a wall of surrounding gas. Astronomers estimate that light from the supernova explosion reached Earth about 1,700 years ago, or when the Mayan empire was flourishing and the Jin dynasty ruled China. However, by cosmic standards the supernova remnant formed by the explosion, called MSH 15-52, is one of the youngest in the Milky Way galaxy. The explosion also created ...

UMD introduces new CRISPR 3.0 system for highly efficient gene activation in plants

In a study in Nature Plants, Yiping Qi, associate professor of Plant Science at the University of Maryland (UMD), introduces a new and improved CRISPR 3.0 system in plants, focusing on gene activation instead of traditional gene editing. This third generation CRISPR system focuses on multiplexed gene activation, meaning that it can boost the function of multiple genes simultaneously. According to the researchers, this system boasts four to six times the activation capacity of current state-of-the-art CRISPR technology, demonstrating high accuracy and efficiency in up to seven genes at once. While CRISPR is more often known for its gene editing capabilities that can knock out genes that are undesirable, activating genes to gain functionality is essential to creating better plants ...

How neurons get past 'no'

LA JOLLA--(June 24, 2021) When looking at a complex landscape, the eye needs to focus in on important details without losing the big picture--a charging lion in a jungle, for example. Now, a new study by Salk scientists shows how inhibitory neurons play a critical role in this process. The study, published May 25, 2021, in the journal Cell Reports, shows that inhibitory neurons do more than just inhibit neuron activity like an off-switch; paradoxically, they actually increase the amount of information transmitted through the nervous system when it needs to be flexible. To make this possible, inhibitory neurons need to be integrated into the circuit in a specific way. These observations could help scientists better understand and treat disorders involving our ability to focus and modulate ...

Rude behavior at work not an epidemic, new study shows

Rude behavior at work has come to be expected, like donuts in the breakroom. Two decades of research on employee relationships shows that 98 percent of employees experience rude behavior at work, but now a new study suggests a large majority of workplace relationships are not characterized by rudeness. Isolated incidents of rude behavior at work, although somewhat common, do not point to widespread incivility between employees and their colleagues, according to a new UCF study. "Because prior research suggests workplace mistreatment is harmful and widespread, it is often called an epidemic, but our findings show that rude behavior is less like the flu and more like cholera," says Shannon Taylor, an associate professor of management and co-author of the ...

Glial cells help mitigate neurological damage in Huntington's disease

The brain is not a passive recipient of injury or disease. Research has shown that when neurons die and disrupt the natural flow of information they maintain with other neurons, the brain compensates by redirecting communications through other neuronal networks. This adjustment or rewiring continues until the damage goes beyond compensation. This process of adjustment, a result of the brain's plasticity, or its ability to change or reorganize neural networks, occurs in neurodegenerative conditions such as Alzheimer's, Parkinson's and Huntington's disease (HD). As the conditions progress, many genes change the way they are normally expressed, turning some genes up and others down. The challenge for researchers like Dr. Juan Botas ...
