We report the synthesis and evaluation as potential anticancer agents of a series of tetracyclic indenoquinolines. The compounds, which are obtained through the photoisomerization of Diels-Alder adducts formed between purpurogallin derivatives and nitrosobenzene, have in vitro antiproliferative activities in the μM to nM range against breast (MCF-7), lung epithelial (A-549), and cervical (HeLa) adenocarcinoma cells. The cytotoxicities of several of the novel tetracycles are comparable to or better than that of camptothecin. A strong correlation between the activity of the compounds and their aromaticity and planarity was observed, suggesting a mode of action similar to that of topoisomerase poisons.

Background: Tennis is a globally popular sport offering physical benefits but poses a high risk of injury due to its demands and prolonged gameplay. While injuries are common among professional players, detailed injury data for this group is limited.
Objective: This review aims to analyze trends in the incidence, type, region, and onset of injuries in professional tennis players, with particular attention to gender distribution, to improve guidelines and reduce injury impacts on performance and career longevity.

Background: Cold-water immersion (CWI) has gained popularity as a health and wellbeing intervention among the general population.
Objective: This systematic review and meta-analysis aimed to evaluate the psychological, cognitive, and physiological effects of CWI in healthy adults.
Methods: Electronic databases were searched for randomized trials involving healthy adults aged ≥ 18 years undergoing acute or long-term CWI exposure via cold shower, ice bath, or plunge with water temperature ≤15°C for at least 30 seconds.
NADPH oxidase derived ROS promote arterial contraction in early postnatal rats by activation of L-type voltage-gated Ca channels.

Reactive oxygen species (ROS) produced by NADPH oxidase promote contraction of peripheral arteries, which is especially pronounced in early postnatal period in comparison to adulthood, but the mechanisms of such vasomotor influence are poorly understood. We tested the hypothesis that Rho-kinase and protein kinase C (PKC) mediate procontractile influence of NADPH oxidase derived ROS in peripheral artery of early postnatal rats. In addition, we evaluated the involvement Src-kinase and L-type voltage-gated Ca channels (LTCC) into procontractile influence of ROS, produced by NADPH oxidase, because of their known interplay with Rho-kinase and PKC pathways.

Cold atmospheric plasma (CAP) has emerged as a promising technology for neutralizing microbes, including multidrug-resistant strains. This study investigates CAP's potential as an alternative to traditional antimicrobial drugs for microbial inactivation. In the era of increasing antimicrobial resistance, there is a persistent need for alternative antimicrobial strategies.

Gene editing is emerging as a powerful tool for introducing novel functionalities in mushrooms. While CRISPR/Cas9-induced double-strand breaks (DSBs) typically rely on non-homologous end joining (NHEJ) for gene disruption, precise insertion of heterologous DNA in mushrooms is less explored. Here, we evaluated the efficacy of inserting donor DNAs (8-1008 bp) with or without homologous arms at Cas9-gRNA RNP-induced DSBs.
