Profs. Okujima and Uno at Ehime University, in collaboration with Prof. Kobayashi at Shinshu University, reported the selective synthesis, the molecular structure, optical properties and electronic structure of cyclo[9]pyrrole, a ring-expanded porphyrin consisting of directly connected pyrrole rings.
The Earth is a sphere, and it comprises spheres: atmosphere, hydrosphere, cryosphere, lithosphere and biosphere -- in short, all of the cycles that interact to influence Earth's weather and climate. Now, to better research how the spheres interact and impact the planet, China is launching EarthLab in Beijing.
A paper published in the prestigious journal Nature Medicine on long-COVID, describes persistent symptoms six months after acute COVID-19, even in young home isolated people.
The study from the Bergen COVID-19 Research Group followed infected patients during the first pandemic wave in Bergen Norway.
"The main novel finding is that more than fifty per cent of young adults up to 30 years old, isolated at home, still have persistent symptoms six months after mild to moderate disease", the leader of the group, Professor Nina Langeland explains.
A rare genetic defect that affects the so-called ALG2 gene can cause serious metabolic diseases in humans. It does so through the defective formation of proteins and sugar molecules. Until now, its rareness and complexity made it difficult to study this congenital glycosylation disorder. A research team led by Prof.
Several eye clinics around Sweden are seeing a rise in eye damage related to the racket sport padel. In an article in the Journal of the Swedish Medical Association (Läkartidningen), eye researchers affiliated with the University of Gothenburg state that padel is a potential high-risk sport for eye injuries, and that wearing protective goggles is a good idea.
A sensitive blood test being developed by a team of researchers at the University of Michigan Rogel Cancer Center shows promise for predicting whether patients with metastatic HPV-positive throat cancer will respond to treatment months earlier than standard imaging scans.
That's according to a study, published in Oncotarget, validating the test in a small group of patients with metastatic human papillomavirus-related oropharyngeal squamous cell carcinoma -- a type of head and neck cancer that develops in the back of the mouth and in the throat.
Pairing blueberry pie with a scoop of ice cream is a nice summer treat. Aside from being tasty, this combination might also help people take up more of the "superfruit's" nutrients, such as anthocyanins. Researchers reporting in ACS' Journal of Agricultural and Food Chemistry show that α-casein, a protein found in cow's milk, helped rats absorb more blueberry anthocyanins and their byproducts, boosting accessibility to these good-for-you nutrients.
For patients who have inflammatory bowel syndrome (IBS), the condition is literally a pain in the gut. Chronic -- or long-term -- abdominal pain is common, and there are currently no effective treatment options for this debilitating symptom. In a new study in ACS Pharmacology & Translational Science, researchers identify a new potential source of relief: a molecule derived from spider venom. In experiments with mice, they found that one dose could stop symptoms associated with IBS pain.
Air quality varies greatly within regions and cities around the world, and exposure to air pollution can have severe health impacts. In the U.S., people of color are disproportionately exposed to poor air quality. A cover story in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, highlights how scientists and community activists are using new technologies to gather data that could help address this inequity.
Previous research was falsely reassuring; captured only 2% of cirrhosis patients
Findings underscore lack of access to health care for Black patients
Cirrhosis is leading cause of death and affects more than 600,000 people in U.S.
CHICAGO --- Black patients with cirrhosis - late-stage liver disease - are about 25% more likely to die compared to non-Hispanic white patients and four times less likely to receive a liver transplant, reports a new Northwestern Medicine study.
BUFFALO, N.Y. -- The giant plumose anemone is an animal, but it looks a bit like an underwater cauliflower. Its body consists of a stalk-like column that attaches to rocks and other surfaces on one end, and to a crown of tentacles on the other.
The anemones use these feelers to collect and shove food into their mouths, and a new study provides an in-depth look into the rich diversity of prey the anemones are catching. This includes a surprising menu item: ants, specifically the pale-legged field ant, Lasius pallitarsis. And the occasional spider.
How long do virus-laden particles persist in an elevator after a person infected with COVID-19 leaves? And is there a way to detect those particles? A group of electrical engineers and computer scientists at KAUST set out to answer these questions using mathematical fluid dynamics equations.
"We found1 that virus-laden particles can still be detected several minutes after a short elevator trip by an infected person," says KAUST electrical engineer Osama Amin.
Researchers from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences have discovered a 120-million-year-old partial fossil skeleton of a tiny extinct bird that fits in the palm of the hand and preserves a unique skull with a mix of dinosaurian and bird features.
The stink of ammonia in urine, sweat, and rotting meat repels humans, but many insects find ammonia alluring. Now, UConn researchers have figured out how the annoying insects smell it, a discovery that could lead to better ways to make them buzz off.
The sense of smell is enormously important. Mammals devote a third of their genetic code to odor receptors found in the nose, and have more than 1,000 different kinds that allow us to smell an estimated trillion different odors.
A new biocompatible polymer-based composite material could soon replace metal plates in treating difficult and unstable fractures. Developed at KTH Royal Institute of Technology in Stockholm, the newly-developed material is as strong as dental composites yet non-toxic.
The material and a surgical method, which were published in Advanced Functional Materials, will be used in clinical studies in 2023 and 2024, with a focus on hand fractures.
