Long-term body mass index variability and adverse cardiovascular outcomes

JAMA Network Open

2024-03-21

(Press-News.org) About The Study: This analysis including 157,000 individuals from two large study cohorts found that among U.S. veterans, higher body mass index (BMI) variability was a significant risk marker associated with adverse cardiovascular events independent of mean BMI across major racial and ethnic groups. Results were consistent in the UK Biobank for the cardiovascular death end point. Further studies should investigate the phenotype of high BMI variability.

Postconcussive symptoms after early childhood concussion

2024-03-21

About The Study: In this early childhood study including 303 children, concussion was associated with more postconcussive symptoms than orthopedic injuries or typical development up to three months after injury. Given the limited verbal and cognitive abilities typical of early childhood, using developmentally appropriate manifestations and behaviors is a valuable way of tracking postconcussive symptoms and could aid in concussion diagnosis in young children. Authors: Miriam Beauchamp, Ph.D., of the Universite de Montreal, is the corresponding author. To access the embargoed study: Visit our For The Media website at ...

Entanglements of humpback whales in fish farms rare – and naivety could be to blame

2024-03-21

The first study of humpback whale entanglements in B.C. aquaculture facilities in PLOS One found eight over 13 years, with the curiosity of young whales a potential contributing factor. A rare occurrence Entanglements are one of several threats to humpbacks. The eight occurred from 2008 to 2021 at seven fish farms, with five animals successfully released and three deaths. The entanglements accounted for less than six per cent of all entanglements in B.C. Approximately 7,000 animals return to B.C. waters annually. Most whales became entangled between the predator and containment nets on fish farms. In five cases, experienced ...

Opto-RANK: A light switch for osteoclasts

2024-03-21

Tokyo, Japan – Drinking milk helps your bones grow big and strong; but what if direct exposure to light could help too? Now, researchers from Japan report that lighting up bone tissue could help treat bone disease. In a study published last month in Scientific Reports, researchers from Tokyo Medical and Dental University (TMDU) have revealed that a treatment approach based on light could help activate bones to repair themselves. Bones are constantly being remodeled through the action of osteoclasts, which break down bone tissue, and osteoblasts, which create new bone tissue. ...

Connecting computers so they can think faster

2024-03-21

We are used to computers getting faster and faster, but complicated calculations involving lots of data can take a very long time, even today. This applies to calculations of chemical reactions, how proteins assume different three-dimensional forms and so-called phase transitions, where one chemical substance transitions from one state to another, such as from solid to liquid form. These types of results are often very important – for example, in the chemical industry. Down from one year to ten days These complicated calculations can take years to perform, and access to the most ...

In-situ observation of nanoscale heat propagation

2024-03-21

1. A NIMS research team has developed a technique that enables the nanoscale observation of heat propagation paths and behavior within material specimens. This was achieved using a scanning transmission electron microscope (STEM) capable of emitting a pulsed electron beam and a nanosized thermocouple—a high-precision temperature measurement device developed by NIMS. 2. Public interest in energy conservation and recycling has grown considerably in recent years. This change has inspired scientists to develop next-generation materials/devices capable of controlling and utilizing heat with a high degree of precision, including thermoelectric devices able to ...

Recent advances and perspectives of covalent organic frameworks for alkali-ion batteries

2024-03-21

They published their work on Mar. 15th in Energy Material Advances. "It is highly necessary to design highly conductive and high-performance materials for application in alkaline ion batteries," said paper author Xijun Xu, associate Professor at the College of Chemical Engineering and Light Industry, Guangdong University of Technology. "In recent years, with the development of large-scale power systems such as electric vehicles, the demand for secondary batteries has gradually shifted towards high power and low cost. Furthermore, in light of the increasing energy and environmental concerns, the exploration of green and renewable ...

Limitations and strategies towards high-performance red phosphorus materials for Li/Na-Ion batteries

2024-03-21

They published their work on Mar. 15th in Energy Material Advances. "The development of cost-effective and high-performance RP anode materials for LIBs/SIBs is imperative," said paper author Hailei Zhao, professor with the Beijing Key Lab of New Energy Materials and Technology, School of Materials Science and Engineering, University of Science and Technology Beijing, "Despite RP shows a great potential, the inherent poor electrical conductivity of RP (~10-14 S cm-1) and significant volume changes during charge/discharge processes (> 300%) compromise its cycling stability." Zhao explained that the poor electrical conductivity ...

New geological study: Scandinavia was born in Greenland

2024-03-21

In a Finnish outcrop nestled between some of Northern Europe's oldest mountains, researchers have found traces of a previously hidden part of Earth's crust that points more than three billion years back in time and north towards Greenland. These traces were found in the mineral zircon, which after chemical analyses, indicated to researchers from the Department of Geosciences and Natural Resource Management that the "foundation" upon which Denmark and Scandinavia rest, was probably 'born' from Greenland approximately 3.75 billion years ago. "Our data suggest that the oldest part of Earth's crust beneath Scandinavia originates ...

Research offers hope for preventing post-COVID ‘brain fog’ by targeting brain’s blood vessels

2024-03-21

Among the many confounding symptoms in patients recovering from a COVID-19 infection are memory loss and difficulty learning. Yet little is known about the mechanisms of cognitive impairments like these, commonly called brain fog. In a new study, researchers at the University of Illinois Chicago have identified a mechanism that causes neurological problems in mice infected with SARS-CoV-2, the virus behind COVID-19. The researchers also found a treatment that helped prevent these changes. Sarah Lutz, assistant professor of anatomy and cell biology in the College of Medicine, led the research, ...

Non-culturable Legionella identified with sequencing

2024-03-21

Highlights: Legionnaires’ disease is a rare and dangerous respiratory tract infection. Diagnoses and surveillance usually require culturing isolates. A new study shows how whole genome sequencing could be used when culturing isn’t an option. The work points to new avenues for public health surveillance of infectious diseases. Washington, D.C.—Legionnaires’ disease (LD), a rare and severe type of pneumonia, is a respiratory infection caused by species of Legionella bacteria. One of the most accurate ways to diagnose LD is to perform culture on samples from a patient’s lower respiratory tract, but those samples are difficult ...
