King's College London researchers have found evidence that minocycline, a widely used antibiotic with anti-inflammatory properties, gave greater improvement in depressive symptoms in patients with treatment resistant depression with low-grade peripheral inflammation.
Improvement in depressive symptoms
In a four-week randomised clinical MINDEP (MINocycline in DEPression) trial, 39 patients with major depressive disorder were recruited from services linked to South London and Maudsley NHS Foundation Trust (SLaM) and via public advertisement.
(Boston)--Researchers from Boston University School of Medicine (BUSM) have identified proteins that are essential for the viability of whole genome doubled tumor cells, yet non-essential to normal cells that comprise the majority of human tissue.
The Asia Pacific Consortium on Osteoporosis (APCO) has today launched the first pan-Asia Pacific clinical practice standards for the screening, diagnosis, and management of osteoporosis, targeting a broad range of high-risk groups.
Published in Osteoporosis International today, 'The APCO Framework' comprises 16 minimum clinical standards set to serve as a benchmark for the provision of optimal osteoporosis care in the region.
Neurons, the fundamental units of the brain, are complex computers by themselves. They receive input signals on a tree-like structure - the dendrite. This structure does more than simply collect the input signals: it integrates and compares them to find those special combinations that are important for the neurons' role in the brain. Moreover, the dendrites of neurons come in a variety of shapes and forms, indicating that distinct neurons may have separate roles in the brain.
A simple yet faithful model
Among infectious diseases that have caused pandemics and epidemics, smallpox stands out as a success story. Smallpox vaccination led to the disease's eradication in the twentieth century. Until very recently, smallpox vaccine was delivered using a technique known as skin scarification (s.s.), in which the skin is repeatedly scratched with a needle before a solution of the vaccine is applied. Almost all other vaccines today are delivered via intramuscular injection, with a needle going directly into the muscle, or through subcutaneous injection to the layer of tissue beneath the skin.
In 2016, a team led by UCLA's Martin Monti reported that a 25-year-old man recovering from a coma had made remarkable progress following a treatment to jump-start his brain using ultrasound.
Wired U.K. called the news one of the best things that happened in 2016. At the time, Monti acknowledged that although he was encouraged by the outcome, it was possible the scientists had gotten a little lucky.
LOS ALAMOS, N.M., January 27, 2021--A new 3D analysis shows that wildland fires flare up in forests populated by similar-sized trees or checkerboarded by large clearings and slow down where trees are more varied. The research can help fire managers better understand the physics and dynamics of fire to improve fire-behavior forecasts.
Imagine a 7-year-old and a college student both take a break from their virtual classes to get a drink of water. When they return, the 7-year-old has difficulty restarting the assignment, while the college student resumes working as if the break never occurred. Nelson Cowan, an expert in working memory at the University of Missouri, believes understanding this developmental age difference can help younger children and their parents to better adjust to a virtual learning environment during the COVID-19 pandemic.
WASHINGTON, DC - Investigators leading the Lung Cancer Master Protocol, or Lung-MAP trial, will present findings from three translational medicine studies at the 2020 World Conference on Lung Cancer, to be held online January 28-31, 2021.
Plastic is ubiquitous in people's lives. Yet, when plastic-containing items have fulfilled their missions, only a small amount is recycled into new products, which are often of lower quality compared to the original material. And, transforming this waste into high-value chemicals requires substantial energy. Now, researchers reporting in ACS' JACS Au have combined a ruthenium-carbon catalyst and mild, lower-energy reaction conditions to convert plastics used in bottles and other packaging into fuels and chemical feedstock.
What makes cancer cells different from ordinary cells in our bodies? Can these differences be used to strike at them and paralyze their activity? Cancer researchers have been debating this question since the mid-19th century.
Cells don't express all the genes they contain all the time. The portion of our genome that encodes eye color, for example, doesn't need to be turned on in liver cells. In plants, genes encoding the structure of a flower can be turned off in cells that will form a leaf.
These unneeded genes are kept from becoming active by being stowed in dense chromatin, a tightly packed bundle of genetic material laced with proteins.
Gardeners and farmers around the country recognize that crop varieties grow best in certain regions. Most plant species have adapted to their local environments; for example, crop and ornamental seeds sold for the upper Midwest are often very different than those bred for Texas. Identifying and breeding varieties that have high productivity across a range of environments is becoming increasingly important for food, fuel and other applications, and breeders aren't interested in waiting decades to develop new crops.
The development of cost-efficient, portable microscopy units would greatly expand their use in remote field locations and in places with fewer resources, potentially leading to easier on-site analysis of contaminants such as E. coli in water sources as well as other practical applications.
In September, a team led by astronomers in the United Kingdom announced that they had detected the chemical phosphine in the thick clouds of Venus. The team's reported detection, based on observations by two Earth-based radio telescopes, surprised many Venus experts. Earth's atmosphere contains small amounts of phosphine, which may be produced by life. Phosphine on Venus generated buzz that the planet, often succinctly touted as a "hellscape," could somehow harbor life within its acidic clouds.
