The efficient strategy for waste conversion and resource recovery is of great interest in the sustainable bioeconomy context. This work reports on the catalytic upcycling of waste corrugated cardboard (WCC) into lactic acid using lanthanide triflates catalysts. WCC, a primary contributor to municipal solid wastes, has been viewed as a feedstock for producing a wide range of renewable products. Hydrothermal conversion of WCC was carried out in the presence of several lanthanide triflates. The reaction with erbium(III) triflate (Er(OTf)) and ytterbium(III) triflate (Yb(OTf)) resulted in high lactic acid yields, 65.5 and 64.3 mol%, respectively. In addition, various monomeric phenols were readily obtained as a co-product stream, opening up opportunities in waste management and resource recovery. Finally, technoeconomic analysis was conducted based on the experimental results, which suggests a significant economic benefit of chemocatalytic upcycling of WCC into lactic acid.

The hypoxic environment of solid tumors significantly diminishes the therapeutic efficacy of oxygen-dependent photodynamic therapy. Developing efficient photosensitizers that operate photoredox catalysis presents a promising strategy to overcome this challenge. Herein, we report the rational design of two rhenium(I) tricarbonyl complexes ( and ) with electron donor-acceptor-donor configuration.

The clinical application of doxorubicin (DOX) is limited due to its cardiotoxicity, which is primarily attributed to its interaction with iron in mitochondria, leading to lipid peroxidation and myocardial ferroptosis. This study aimed to investigate the role of the gut microbiota-derived metabolite, indole-3-lactic acid (ILA), in mitigating DOX-induced cardiotoxicity (DIC). Cardiac function, pathological changes, and myocardial ferroptosis were assessed in vivo.

The lactic acid bacterial (LAB) species have proven multifaceted roles in sustainable agriculture due to their biologically safe nature, making them eco-friendly. However, their plant growth-improving mechanisms in stressed and non-stressed conditions are still under consideration. Thus, the current work has been planned to evaluate the drought tolerance potential and plant growth-promoting (PGP) traits of Loigolactobacillus coryniformis BCH-4 in Zea mays L.

Introduction: Sepsis is a systemic process that refers to a deregulated immune response of the host against an infectious agent, involving multiple organ dysfunction. It is rapidly progressive and has a dismal prognosis, with high mortality rates. For this reason, it is necessary to have a tool for early recognition of these patients, with the aim of treating them appropriately in a timely manner.
