Gold catalysts supported on alumina (Au/Al2O3) and zinc oxide/Al2O3 (Au/ZnO/Al2O3) were prepared by deposition-precipitation with ammonium bicarbonate, and were characterized by nitrogen gas adsorption, X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, and temperature programmed reduction. The effect of ZnO addition to the surface of Al2O3 on the catalytic activity of Al2O3-supported gold catalysts in carbon monoxide oxidation is discussed in detail. The additions of 4 wt% ZnO loading to Au/Al2O3 showed a higher degree of gold particle dispersion which resulted in higher catalytic activity with Au/ZnO/Al2O3 catalyst than with Au/Al2O3 catalyst.

Dual Pathways of Photorelease Carbon Monoxide via Photosensitization for Tumor Treatment.

R. China.
Carbon monoxide (CO) gas therapy, as an emerging therapeutic strategy, is promising in tumor treatment. However, the development of a red or near-infrared light-driven efficient CO release strategy is still challenging due to the limited physicochemical characteristics of the photoactivated carbon monoxide-releasing molecules (photoCORMs). Here, we discovered a novel photorelease CO mechanism that involved dual pathways of CO release via photosensitization.

The objective of the current review was to identify whether clinically established lung function metrics of ventilatory and diffusion capacity obtained by standardised methodology are consistent with superior lung function in athletes, and whether this is related to maximal oxygen uptake (V̇O). Three independent reviewers performed a literature search in PubMed, Scopus, and reference screening. Data was extracted and analysed according to a predefined strategy.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to widespread post-acute sequelae of COVID-19 (PASC), affecting multiple body systems. Despite its prevalence, PASC's pathogenesis remains unclear, with hypotheses suggesting viral persistence, immune activation, and autoimmune responses among the pathogenetic mechanism. This study aimed to evaluate T cell memory response in PASC patients, one year post-hospital discharge and correlate it with clinical parameters to identify a potential PASC-associated fingerprint.

Background: The KOTAK program is a national public health initiative in Malaysian primary and secondary schools aimed at reducing youth smoking through school dental services. This study evaluated its effectiveness in Seremban, Negeri Sembilan, Malaysia.
Objectives: 1) To determine the percentage of schoolchildren who quit smoking through the KOTAK program; 2) To identify factors associated with quitting smoking in the program.
A Systematic Review and Meta-Analysis Assessing the Impact of Improved Cookstove Technology Trials (ICTs) on Household Air Pollution and Human Health in Sub-Saharan Africa.

Purpose Of Review: A major contributor to household air pollution (HAP) in sub-Saharan Africa (SSA) is unclean cooking fuel. Improved cookstove technology (ICT) interventions have been promoted as a solution, but their impacts on health are unclear. Our aim is to conduct a systematic review to explore the impacts of ICT interventions on health outcomes in SSA.
