(Press-News.org) About The Study: This study revealed a U-shaped association between adolescent body mass index and mental health, which was consistent across sex and grades and became stronger over time. These insights emphasize the need for targeted interventions addressing body image and mental health, and call for further research into underlying mechanisms.

The doctor is in…. but what’s behind them?
2024-05-15
Americans have gotten used to seeing their doctors and other health care providers using telehealth video visits in the past four years. But a new study reveals that what a doctor has behind them during a telehealth visit can make a difference in how the patient feels about them and their care.
Even if the doctor is miles away from their usual in-person clinic or exam room, they should make it look like they’re there, the study suggests.
Even better: sitting in an office with their diplomas hanging ...
Structural evolution and high-temperature sensing performance of polymer-derived SiAlBCN ceramics
2024-05-15
The group of Gang Shao from Zhengzhou University, China recently investigated the structural evolution of pentagonal polymer-derived SiAlBCN ceramics (PDCs) and outlined PDC-based sensor technology for high-temperature extreme environments. The high-performance temperature sensing materials including high sensitivity, fast response, wide detection range are scarce and needful. This research developed a ceramic-based temperature with attractive performance that can be applied in high-temperature environments ...
An environmental CGE model of China’s economy: Modeling choices and application
2024-05-15
The general equilibrium framework of the CGE model widely used in cost-benefit analysis in the field of energy and environmental policy. Based on standard micro- and macroeconomic theories, the CGE model establishes quantitative connections between various sectors of the economy, enabling the examination of both direct and indirect effects resulting from exogenous changes in the economy, as well as their global impacts on the overall economy.
A team of energy economists by Yu Liu from Peking University in Beijing, China recently outlined the detailed content of their CGE model. This model is constructed based on the CGE model theory of the Australian Center ...
Adding polymerized ionic liquid improves performance of perovskite solar cells
2024-05-15
Perovskite solar cells, which use materials with the same crystal structure as perovskite, are lightweight, flexible, easy to manufacture, and inexpensive. They can be attached to many different surfaces and are a promising technology. However, current perovskite solar cells are not durable, and they tend to be inefficient. New research shows how additive engineering with a polymerized ionic liquid to the metal halide perovskite material can improve the solar cell’s function, helping to pave the way for the future wide adoption of perovskite solar ...
Half-matched family donors offer best outcomes for Hispanic patients undergoing bone marrow transplants
2024-05-15
LOS ANGELES — For adults with acute lymphoblastic leukemia (ALL), a type of cancer that originates in the bone marrow, allogeneic stem cell transplantation (more commonly known as a bone marrow transplant) may be necessary for survival. But for Hispanic patients, finding an identically matched donor within their family or through the bone marrow donor registry can be challenging, with only a 30% chance of finding a matching relative and a 48% chance of identifying a matching bone marrow donor through the national donor registry.
However, a new Keck Medicine of USC study in Leukemia ...
Alzheimer’s disease without symptoms. How is that possible?
2024-05-15
Everyone experiences aging in their own way, and factors such as genetics, lifestyle and environment play a role in this process. Some individuals reach the age of 90 or even 100 in good health, without medications or brain disease. But how do these individuals maintain their health as they age?
Luuk de Vries from Joost Verhaagen's group, and his colleagues Dick Swaab and Inge Huitinga, looked at brains from the Netherlands Brain Bank. The Netherlands Brain Bank stores brain tissue from more than 5,000 deceased brain donors with a wide range of different brain diseases. What makes the Netherlands Brain Bank so unique is that, in addition to the stored tissue with very precise ...
Mesenchymal stem cells alleviate acute liver failure through regulating hepatocyte apoptosis and macrophage polarization
2024-05-15
Background and Aims
Acute liver failure (ALF) is a life-threatening clinical problem with limited treatment options. Administration of human umbilical cord mesenchymal stem cells (hUC-MSCs) may be a promising approach for ALF. This study aimed to explore the role of hUC-MSCs in the treatment of ALF and the underlying mechanisms.
Methods
A mouse model of ALF was induced by lipopolysaccharide and d-galactosamine administration. The therapeutic effects of hUC-MSCs were evaluated by assessing serum enzyme activity, histological appearance, and cell apoptosis in liver tissues. The apoptosis ...
Avian flu detected in New York City wild birds
2024-05-15
Washington, D.C.— May 15, 2024—A small number of New York City wild birds carry highly pathogenic H5N1 avian influenza, according to a recent study published in the Journal of Virology, a journal of the American Society for Microbiology. The work highlights that the interface between animals and humans that may give rise to zoonotic infections or even pandemics is not limited to rural environments and commercial poultry operations, but extends into urban centers.
“To my knowledge, this is the first large-scale U.S. study of avian influenza in an urban area, and the first with active ...
New campaign aims to empower Asian American communities with lifesaving CPR skills
2024-05-15
DALLAS, May 15, 2024 — Despite strides in cardiopulmonary resuscitation (CPR) training, consumer research from the American Heart Association reveals only 1 in 4 Asian American individuals are confident they could correctly perform Hands-Only CPR, compared with a comparable confidence rate of more 1/3 of the general population. The same survey showed nearly 70% of Asian American adults are hesitant to perform Hands-Only CPR because they are worried they will hurt the person who has suffered ...
Repurposed beer yeast may offer a cost-effective way to remove lead from water
2024-05-15
CAMBRIDGE, MA – Every year, beer breweries generate and discard thousands of tons of surplus yeast. Researchers from MIT and Georgia Tech have now come up with a way to repurpose that yeast to absorb lead from contaminated water.
Through a process called biosorption, yeast can quickly absorb even trace amounts of lead and other heavy metals from water. The researchers showed that they could package the yeast inside hydrogel capsules to create a filter that removes lead from water. Because the yeast cells are encapsulated, they can be easily removed from the water once it’s ready ...
