Fentanyl, heroin, methamphetamine, and cocaine analyte concentrations in urine drug testing specimens

JAMA Network Open

2024-10-24

(Press-News.org) About The Study: This cross-sectional study found that absolute concentrations of fentanyl, methamphetamine, and cocaine in urine specimens increased from 2013 to 2023, with a decrease in heroin concentration during that period. The findings suggest that exposure to these substances, as well as the illicit drug supply, has fundamentally changed in many parts of the U.S., highlighting the need to reinforce surveillance initiatives and accelerate efforts to treat individuals with illicitly manufactured fentanyl and/or stimulant exposure.

UCLA researchers engineer experimental drug for preventing heart failure after heart attacks

2024-10-24

Scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have developed a first-of-its-kind experimental therapy that has the potential to enhance heart repair following a heart attack, preventing the onset of heart failure. Cardiovascular disease continues to be the world’s leading cause of death, contributing to one-third of deaths annually. After a heart attack, the heart’s innate ability to regenerate is limited, causing the muscle to develop scars to maintain its structural integrity. ...

Combining targeted therapy and immunotherapy improves overall survival in patients with anaplastic thyroid cancer

2024-10-24

HOUSTON ― Researchers from The University of Texas MD Anderson Cancer Center demonstrated that anti-PD-L1 immunotherapy in combination with mutation-directed targeted therapy extended overall survival (OS) in patients with anaplastic thyroid carcinoma (ATC). Findings from the Phase II single center study published today in JAMA Oncology. The trial enrolled 42 patients across three cohorts to evaluate mutation-matched targeted therapy and the immune checkpoint inhibitor atezolizumab. The median OS across all cohorts was 19 months, which compares favorably to historical OS of five months for patients with ATC. ...

Assessing the real climate costs of manufacturing

2024-10-24

Producing materials such as steel, plastics and cement in the United States alone inflicts $79 billion a year in climate-related damage around the world, according to a new study by engineers and economists at the University of California, Davis. Accounting for these costs in market prices could encourage progress toward climate-friendly alternatives. “We wanted to look at the cost to society to produce these materials,” said Elisabeth Van Roijen, a recent Ph.D. graduate from the UC Davis Department of Civil and Environmental Engineering ...

A multi-functional simulation platform for on-demand ride service operations

2024-10-24

On-demand ride services or ride-sourcing services have been experiencing fast development and steadily reshaping the way people travel in the past decade. Various optimization algorithms, including reinforcement learning approaches, have been developed to help ride-sourcing platforms design better operational strategies to achieve higher efficiency. However, due to cost and reliability issues, it is commonly infeasible to validate these models and train/test these optimization algorithms within real-world ride-sourcing platforms. Acting as a proper test bed, a simulation platform for ride-sourcing systems will thus be essential for both ...

Research team undertakes review of carbon anodes for lithium-ion batteries

2024-10-24

A team of researchers has undertaken a study of the future of carbon anodes for lithium-ion batteries. Their review provides a comprehensive overview of the progression in carbon anode development and the current status of their industrialization. This study underscores the critical role of interphase regulation engineering in advancing lithium-ion battery technology. Their research is published in the journal Carbon Future on September 24, 2024. Today, graphite is the most commonly used material for anodes in lithium-ion batteries. Graphite can operate at a low voltage, is readily available, and cost effective. While graphite materials ...

Researchers improve speed and accuracy of 3D surface measurements

2024-10-24

WASHINGTON — Researchers have developed a faster and more accurate method for acquiring and reconstructing high-quality 3D surface measurements. The approach could greatly improve the speed and accuracy of surface measurements used for industrial inspection, medical applications, robotic vision and more. “Traditional 3D imaging works by comparing two viewpoints, similar to how our eyes work together to judge depth,” said research team leader Ce Zhu from the University of Electronic Science and Technology of China. “In contrast, our new approach ‘feels’ the surface by projecting light ...

GPX4 promoter hypermethylation induced by ischemia/reperfusion injury regulates hepatocytic ferroptosis

2024-10-24

Background and Aims Glutathione peroxidase 4 (GPX4) is a key factor in ferroptosis, which is involved in ischemia-reperfusion injury. However, little is known about its role in hepatic ischemia-reperfusion injury (HIRI). This study aimed to investigate the role of GPX4 methylation in ferroptosis during HIRI. Methods For the in vivo experiments, an ischemia-reperfusion model was created by subjecting mice to simulated HIRI. Ferroptosis occurrence, GPX4 promoter methylation, and global methylation levels were then assessed. Results Ferroptosis ...

Belief in growth is key to becoming the best

2024-10-24

It takes a lot to succeed with ambitious goals. Among other things, we need passion and belief that we will succeed, and we usually need support from others. However, we also need to have the right attitude – the right mindset, one that makes us willing to do what it takes to change and improve. Experts refer to it as a growth mindset. So, how do we know if we actually have the right mindset? How can a coach know if a talented athlete has the mindset needed to become one of the best? An individual’s mindset is influenced by external factors that can change, and it may also vary from day to ...
