Methylcrotonyl-CoA carboxylase 2 supports leucine catabolism to promote mitochondrial biogenesis and alleviate cisplatin-induced acute kidney injury.

Background: Cisplatin is widely used in clinical practice, but its nephrotoxicity severely limits its use. Previous studies have shown that cisplatin-induced acute kidney injury (AKI) is closely related to mitochondrial damage and that alleviating mitochondrial dysfunction can alleviate cisplatin-induced AKI. Methylcrotonyl‑CoA carboxylase 2 (MCCC2) is mainly located in mitochondria, where it catalyzes the catabolism of leucine and maintains mitochondrial function; however, the role of MCCC2 in cisplatin-induced renal injury has not yet been studied.

Inhalable nanovesicles loaded with a STING agonist enhance CAR-T cell activity against solid tumors in the lung.

Suppression of chimeric antigen receptor-modified T (CAR-T) cells by the immunosuppressive tumor microenvironment remains a major barrier to their efficacy against solid tumors. To address this, we develop an anti-PD-L1-expressing nanovesicle loaded with the STING agonist cGAMP (aPD-L1 NVs@cGAMP) to remodel the tumor microenvironment and thereby enhance CAR-T cell activity. Following pulmonary delivery, the nanovesicles rapidly accumulate in the lung and selectively deliver STING agonists to PD-L1-overexpressing cells via the PD-1/PD-L1 interaction.

Mutation of lysine-specific demethylase 5 is associated with enhanced tumor immunity and favorable outcomes in pan-cancer immune checkpoint blockade.

The lysine-specific demethylase 5 (KDM5) family, a key post-translational modification of chromatin, can shape tumor immune microenvironment. Here, we performed an extensive clinical and bioinformatic analysis to explore the association between KDM5 mutation and tumor immunity and its impact on the outcomes in pan-cancer immunotherapy. In 2943 patients across 12 tumor types treated with immune checkpoint inhibitors, KDM5-mutant tumors were associated with favorable overall survival (hazard ratio, 0.

Knockdown of RASD1 improves MASLD progression by inhibiting the PI3K/AKT/mTOR pathway.

Background: There is still no reliable therapeutic targets and effective pharmacotherapy for metabolic dysfunction-associated steatotic liver disease (MASLD). RASD1 is short for Ras-related dexamethasone-induced 1, a pivotal factor in various metabolism processes of Human. However, the role of RASD1 remains poorly illustrated in MASLD.

Association between the geriatric nutritional risk index and postoperative delirium in gastric surgery patients: an analysis of the MIMIC-IV database.

Background: This study explores the correlation between nutritional status, as determined by the Geriatric Nutritional Risk Index (GNRI), and the incidence of postoperative delirium (POD) in patients undergoing gastric surgery.

Methods: Data were obtained from the MIMIC-IV 2.2 database for patients aged 18 years or older who underwent gastric surgery.

Association of triglyceride glucose-body mass index and left ventricular hypertrophy in patients with IgA nephropathy: a retrospective study.

Introduction: IgA nephropathy (IgAN) is one of the most prevalent forms of glomerulonephritis worldwide, particularly affecting 40-50% of the East Asian population. Cardiovascular mortality represents a leading cause of death in patients with IgAN. Left ventricular hypertrophy (LVH) serves as a predictor of heart failure and cardiovascular mortality.

Clinical effectiveness of unilateral single-armed vasoepididymostomy in obstructive azoospermia: a single-center experience.

Background: Vasoepididymostomy (VE) is an important surgical treatment to achieve natural conception for patients with obstructive azoospermia (OA), and only unilateral VE can be performed under certain conditions, such as OA patients with congenital unilateral absence of the vas deferens (CUAVD) and some acquired OA. There is a lack of relevant reports assessing the clinical outcomes of unilateral VE in OA patients with different causes. This study is aimed to describe the clinical features and evaluate treatments and outcomes of unilateral single-armed VE in OA patients.

Deep learning-based low count whole-body positron emission tomography denoising incorporating computed tomography priors.

Background: Deep-learning-based denoising improves image quality and quantification accuracy for low count (LC) positron emission tomography (PET). Conventional deep-learning-based denoising methods only require single LC PET image input. This study aims to propose a deep-learning-based LC PET denoising method incorporating computed tomography (CT) priors to further reduce the dose level.

The influence between plaque rupture and non-plaque rupture on clinical outcomes in patients with ST-segment elevation myocardial infarction after primary percutaneous coronary intervention: a prospective cohort study.

Background: Coronary atherosclerosis can lead to acute clinical events upon atherosclerotic plaque rupture (PR) or erosion and arterial thrombus formation. Identifying the effect of distinct plaque characteristics on clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) is critical for clinical therapy. Our goal was to ascertain the correlation between clinical outcome, long-term prognosis, and morphological plaque characteristics in STEMI.

An increasing body of research indicates a reciprocal and interconnected association between endothelial function and insulin resistance.

Gut Microbiota, Circulating Metabolites and Risk of Endometriosis: A Two-Step Mendelian Randomization Study.

Epidemiological studies and animal models have suggested a possible link between gut microbiota (GM), circulating metabolites, and endometriosis (EMs) pathogenesis. However, whether these associations are causal or merely due to confounding factors remains unclear. We conducted a two-sample and two-step Mendelian randomization (MR) study to elucidate the potential causal relationship between GM and EMs, and the mediating role of circulating metabolites.

FFA intervention on LO2 cells mediates SNX-10 synthesis and regulates MMP9 secretion in LX2 cells via TGF-β1.

Background: Metabolic-associated fatty liver disease (MAFLD) is a public health concern. Transforming growth factor-β1(TGF-β1) plays an important regulatory role in multiple MAFLD stages, as it can promote the expression of matrix metalloproteinase-9 (MMP9) and promote liver fibrosis. Sorting nexin protein-10 (SNX-10) may be involved in the occurrence and development of fatty liver disease.

Background: Observational studies and animal experiments had suggested a potential relationship between gut microbiota abundance and pathogenesis of endometriosis (EMs), but the relevance of this relationship remains to be clarified.

Methods: We perform a two-sample bidirectional Mendelian randomization (MR) analysis to explore whether there is a causal correlation between the abundance of the gut microbiota and EMs and the direction of causality. Genome-wide association study (GWAS) data ukb-d-N80, finn-b-N14-EM, and MiBinGen were selected.

PGAM5 promotes RIPK1-PANoptosome activity by phosphorylating and activating RIPK1 to mediate PANoptosis after subarachnoid hemorrhage in rats.

Neuronal death plays a crucial role in early brain injury after subarachnoid hemorrhage (SAH). PANoptosis is a programmed form of cell death regulated by the PANoptosome, which possesses key characteristics of pyroptosis, apoptosis and necroptosis. Phosphoglycerate mutase family member 5 (PGAM5) has specific phosphatase activity that phosphorylates or dephosphorylates serine and threonine residues on bound proteins such as receptor-interacting protein kinase 1 (RIPK1), which are involved in programmed cell death.
