Photocatalytic Hydrolysis-A Sustainable Option for the Chemical Upcycling of Polylactic Acid.

Plastic waste is a critical global issue, yet current strategies to avoid committing plastic waste to landfills include incineration, gasification, or pyrolysis high carbon emitting and energy consuming approaches. However, plastic waste can become a resource instead of a problem if high value products, such as fine chemicals and liquid fuel molecules, can be liberated from controlled its decomposition. This letter presents proof of concept on a low-cost, low energy approach to controlled decomposition of plastic, photocatalytic hydrolysis.

Left Ventricular Non-compaction Cardiomyopathy: The Key to Its Diagnosis and Implications for Management.

Left ventricular non-compaction (LVNC) cardiomyopathy is a condition with increasing prevalence as cardiac imaging technology improves, although there is currently no diagnostic gold standard. Characterized by the presence of a bilayered myocardium with prominent trabeculations, LVNC cardiomyopathy has a wide range of presentations, from asymptomatic to severe heart failure, thromboembolism, and sudden cardiac death. We present the case of a 62-year-old male who was admitted for a heart failure exacerbation with a worsening ejection fraction and signs of increased trabeculations of the left ventricle on an echocardiogram.

Assessing Vaping Views, Usage, and Vaping-Related Education Among Medical Students: A Pilot Study.

Background E-cigarette use, or vaping, is known to be associated with potentially life-threatening lung injury, with the Centers for Disease Control and Prevention reporting 2,807 hospitalizations and 68 deaths in the United States due to e-cigarette or vaping-associated lung injury. Vaping is also a risk factor for and is implicated in the spreading of COVID-19. Despite the consequences of vaping, the views and training of medical students regarding vaping is unclear.

Effects of a Concentric Rare-Earth Magnet on Menstrual Cycle Pain: A Parallel Group Randomized Pilot Study.

Background Based on prior reports of the use of magnets to treat pain, our goal was to determine if a concentric rare-earth alternating-pole magnet reduced period pain versus a sham-magnet.  Methods Participants were females (N=36, 18 to 35 years) who regularly experienced menstrual period pain ≥ six on the numeric pain rating scale (NPRS) of 0-10. Subjects were excluded if they took pain medication on the study day or had implanted pacemakers/metallic devices or secondary dysmenorrhea.

The food and drug administration and molecular imaging agents: potential challenges and opportunities.

Molecular imaging, which combines the use of traditional imaging modalities with pharmaceutical and biologic imaging agents, holds considerable promise, particularly in light of recent advances in genomics and new applications beyond diagnosis toward the earlier detection and characterization of disease, the reliable assessment of treatment efficacy, and imaging-link therapeutic applications. Its potential notwithstanding, the current U.S.
