WASHINGTON, April 2, 2024 – Hydrogels are popular for use in skin ailments and tissue engineering. These polymer-based biocompatible materials are useful for their abilities to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture and not very resilient to external forces like rubbing against clothing, sheets, or wound dressings. They are also not inherently able to battle bacterial infections, so they are often infused with antimicrobial drugs or metal ions, which can ...

The human body uses adhesion to hold itself together. For example, a tendon attaches muscle to bone, while connective tissue attaches muscle to skin.  Hydrogel-based soft materials are based on these biomimetic mechanical behaviors, which makes them a revolutionary design of biomedical implants, human-machine interfaces, and bio-inspired soft robots. However, there are limitations to overcome before they are able to fully replace commonly used hard materials.  Qihan Liu, assistant professor of mechanical and materials ...

Individuals with heart disease stand to gain the most from a low-sodium diet but, on average, consume over twice the recommended daily sodium intake, according to a study being presented at the American College of Cardiology’s Annual Scientific Session. Sodium is an essential nutrient, but consuming too much can raise blood pressure, which damages blood vessels and forces the heart to work harder. Excess sodium can also cause the body to retain fluid, exacerbating conditions like heart failure. The current U.S. Dietary Guidelines put out by the U.S. Department of Agriculture ...

People who use e-cigarettes are significantly more likely to develop heart failure compared with those who have never used them, according to one of the largest prospective studies to date investigating possible links between vaping and heart failure. The findings are being presented at the American College of Cardiology’s Annual Scientific Session. Heart failure is a condition affecting more than 6 million U.S. adults in which the heart becomes too stiff or too weak to pump blood as effectively as it should. It can often lead to debilitating symptoms and frequent hospitalizations as people age. Electronic nicotine products, which include ...

Investments in mitigating climate change in many cases benefit future generations more than those alive today. However, initial costs must be borne by those living now, so many climate mitigation policies rely on some level of intergenerational altruism for support. To investigate the strength and shape of intergenerational altruism, Gustav Agneman and colleagues asked Swedish study participants to engage in an experimental task in which they allocated fictional resources across generations, after being told how many descendants they might be expected to have in the next 250 years.  On average, participants allocated most of the resources to the present generation, and fewer and ...

The pursuit of carbon neutrality drives the exploration of clean energy sources, with hydrogen fuel cells emerging as a promising avenue. In these cells, hydrogen undergoes an electrochemical reaction with oxygen to produce electricity and water. Also, the reverse of this process, called electrolysis, can be used to split the abundantly available water to produce hydrogen and oxygen. These two technologies can work in tandem to provide a clean and renewable source of energy. A pivotal element in these two technologies is the platinum (Pt) electrode. Hydrogen fuel cells consist of two electrodes: an anode and a cathode, with an ...

Fukuoka, Japan - Researchers at Kyushu University have developed and validated a machine-learning model that can accurately evaluate the density of surviving tumor cells after treatment in pathological images of osteosarcoma—the most prevalent malignant bone tumor. The model can assess how individual tumor cells respond to treatment and can predict overall patient prognosis more reliably than conventional methods. Surgery and chemotherapy have significantly improved the outcomes of patients with localized osteosarcoma. However, patients with advanced metastatic disease (the stage where cancerous cells have spread to distant tissues) have a low survival rate. ...

All-solid-state lithium-ion (Li-ion) batteries with solid electrolytes are non-flammable and have higher energy density and transference numbers than those with liquid electrolytes. They are expected to take a share of the market for conventional liquid electrolyte Li-ion batteries, such as electric vehicles. However, despite these advantages, solid electrolytes have lower Li-ion conductivity and pose challenges in achieving adequate electrode-solid electrolyte contact. While sulfide-based solid electrolytes are conductive, they react with moisture to form toxic hydrogen disulfide. Therefore, there's ...

A new study found that during the pandemic pediatric emergency departments (EDs) saw more children and adolescents who needed a psychiatric admission, as well as an increase in severe conditions, such as bipolar disorder, schizophrenia and substance use disorders. The higher demand for a psychiatric inpatient bed often exceeded availability, resulting in over 12-hour stays in the ED awaiting admission for nearly 20 percent of children with mental health emergencies in 2022, up from 7 percent before the pandemic. Findings were published in Academic Emergency Medicine. “Our data shows that pediatric emergency departments saw more severe mental health presentations during the pandemic, ...
