Bufalin Ameliorates Myocardial Ischemia/Reperfusion Injury by Suppressing Macrophage Pyroptosis via P62 Pathway.

Bufalin, which is isolated from toad venom, exerts positive effects on hearts under pathological circumstance. We aimed to investigate the effects and mechanisms of bufalin on myocardial I/R injury. In vivo, bufalin ameliorated myocardial I/R injury, which characteristics with better ejection function, decreased infarct size and less apoptosis.

Loss-of-function SLC25A20 mutation causes carnitine-acylcarnitine translocase deficiency by reducing SLC25A20 protein stability.

Background/aim: Autosomal-recessive carnitine-acylcarnitine translocase deficiency (CACTD) is a rare disorder of long-chain fatty acid oxidation caused by variants in the SLC25A20 gene. Under fasting conditions, most newborns with severe CACTD experience sudden cardiac arrest and hypotonia, often leading to premature death due to rapid disease progression. Understanding of genetic factors and pathogenic mechanisms in CACTD is essential for its diagnosis, treatment, and prevention.

Anlotinib enhances the pro-apoptotic effect of APG-115 on acute myeloid leukemia cell lines by inhibiting the P13K/AKT signaling pathway.

Background: APG-115 is a novel small-molecule selective inhibitor that destabilizes the p53-MDM2 complex and activates p53-mediated apoptosis in tumor cells. Anlotinib inhibits tumor angiogenesis and promotes apoptosis. In this study, we investigated the apoptotic effect and potential mechanism of APG-115 and anlotinib combination on AML cell lines with different p53 backgrounds.

The impact of transient air pollution exposure on worker performance in Chinese soccer players.

Using a unique dataset on the performance of soccer players in China (retrieved from 632 matches involving 24 teams during the 2014 to 2016 seasons), we investigate the effect of air pollution on different performance indicators that rely on different mixtures of the physical and cognitive inputs of players. To ensure a causal interpretation, we implement an instrumental variable (IV) approach using thermal inversion as the instrument for air pollution. We found that players' performance indicators, especially those more related to cognitive factors, are more strongly influenced by air pollution.

Application of nanomedicines in tumor immunotherapy.

Tumor immunotherapy has emerged as a formidable strategy, demonstrating substantial achievements in the field of cancer treatment. Despite its remarkable success, intrinsic limitations such as insufficient targeting capabilities, side effects, and resistance to immunotherapy hinder its efficacy. To address these challenges, the utilization of nanomedicines in tumor immunotherapy has been broadly explored, capitalizing on their advantages of targeting delivery capability, loading capacity, modifiability, and biocompatibility.
