Unveiling the renoprotective mechanisms of self-assembled herbal nanoparticles from and in acute kidney injury: A nano-TCM approach.

Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. D.

Broussoflavonol B induces S-phase arrest and apoptosis in pancreatic cancer cells by modulating the cell cycle checkpoint through inhibition of the AURKA/PLK1 pathway.

Background: Broussoflavonol B (Bf-B), a flavonoid compound identified in the roots of Daphne giraldii Nitsche, has been extensively investigated for its potential anti-inflammatory, antioxidant, and anticancer properties. However, the precise mechanism underlying the regulation of AURKA/PLK1 pathway-mediated cell cycle arrest by Bf-B in pancreatic cancer remains poorly understood.

Purpose: The objective of this study was to investigate the inhibitory effect of Bf-B on pancreatic ductal adenocarcinoma (PDAC) and its underlying mechanism.

Free water imaging reveals asynchronous dopaminergic degeneration in substantia nigra and ventral tegmental area in prodromal and early Parkinson's disease.

Purpose: The ventral tegmental area (VTA), which is rich in dopaminergic neurons, may play a role in influencing clinical symptoms in Parkinson's Disease (PD). However, the degeneration dynamics of the VTA during the early and prodromal stages of PD remain unclear. This study aims to explore microstructural changes in the VTA among prodromal PD patients with idiopathic REM sleep behavior disorder (iRBD) and early-stage PD patients using free water imaging (FWI) to assess free water (FW) and its correlation with clinical symptoms.

Mitochondrial RNA metabolism, a potential therapeutic target for mitochondria-related diseases.

In recent years, the roles of mitochondrial RNA and its associated human diseases have been reported to increase significantly. Treatments based on mtRNA metabolic processes and nuclear gene mutations are thus discussed. The mitochondrial oxidative phosphorylation process is affected by mtRNA metabolism, including mtRNA production, maturation, stabilization, and degradation, which leads to a variety of inherited human mitochondrial diseases.

Objective: Despite the combination of Scutellaria barbata D. Don and Scleromitrion diffusum (Willd.) R.

Alterations of regional homogeneity and functional connectivity in different hoehn and yahr stages of Parkinson's disease.

Purpose: Using regional homogeneity (ReHo) and functional connectivity (FC) to assess alterations in brain function and their potential relation to different Hoehn and Yahr (H&Y) stages in Parkinson's disease (PD).

Materials And Methods: 66 patients with PD and 57 age- and sex-matched healthy control (HC) participants were recruited. All subjects underwent clinical assessments and resting-state functional magnetic resonance imaging (rs-fMRI) scanning.

Efficacy Assessment of Post-nephrectomy Adjuvant Therapies in Patients with Renal Cell Carcinoma.

Objective: The objective of our study was to integrate the efficacy results of post-nephrectomy adjuvant therapies in renal cell carcinoma (RCC) patients with risk of recurrence, and attempt to determine the optimal intervention choice.

Methods: We performed standard meta-analysis procedures in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The PubMed, Embase, and Cochrane Library databases were searched from inception to 22 September 2022.

Mechanism exploration and biomarker identification of glycemic deterioration in patients with diseases of the exocrine pancreas.

The damage to the endocrine pancreas among patients with diseases of the exocrine pancreas (DP) leads to reduced glycemic deterioration, ultimately resulting in diabetes of the exocrine pancreas (DEP). The present research aims to investigate the mechanism responsible for glycemic deterioration in DP patients, and to identify useful biomarkers, with the ultimate goal of enhancing clinical practice awareness. Gene expression profiles of patients with DP in this study were acquired from the Gene Expression Omnibus database.

What Happens to a Pyrrole Hemithioindigo Photoswitch Trapped in a Fluorescent Protein?

Artificial molecular photoswitches that can be reversibly controlled into different configurations by external light stimulation have broad application prospects in various fields, such as materials and chemical biology. Among them, the pyrrole hemithioindigo (PHT) photoswitch has a geometric structure similar to that of the fluorescent protein chromophore. What happens when the chromophore is replaced by PHT, and does it achieve similar functions to the original one? To answer these questions, we carried out ONIOM(QM/MM) and classical molecular dynamics studies on the photoisomerization mechanism and spectroscopic properties of PHT in the fluorescent protein.

Acyl-CoA synthase ACSL4: an essential target in ferroptosis and fatty acid metabolism.

Long-chain acyl-coenzyme A (CoA) synthase 4 (ACSL4) is an enzyme that esterifies CoA into specific polyunsaturated fatty acids, such as arachidonic acid and adrenic acid. Based on accumulated evidence, the ACSL4-catalyzed biosynthesis of arachidonoyl-CoA contributes to the execution of ferroptosis by triggering phospholipid peroxidation. Ferroptosis is a type of programmed cell death caused by iron-dependent peroxidation of lipids; ACSL4 and glutathione peroxidase 4 positively and negatively regulate ferroptosis, respectively.

Efficacy and safety assessment of mineralocorticoid receptor antagonists in patients with chronic kidney disease.

Background: The objective of our study is to evaluate the efficacy and safety of mineralocorticoid receptor antagonists (MRAs) and determine the optimal MRA treatment regimen in patients with chronic kidney disease (CKD).

Methods: We searched PubMed, Embase, Web of Science, and the Cochrane Library from their inception to June 20, 2022. The composite kidney outcome, cardiovascular events, urinary albumin to creatinine ratio (UACR), estimated glomerular filtration rate (EGFR), serum potassium, systolic blood pressure (SBP), diastolic blood pressure (DBP), creatine and creatine clearance were included for analysis.

Corrigendum: Bibliometric and visualized analysis of drug resistance in ovarian cancer from 2013 to 2022.

Bibliometric and visualized analysis of drug resistance in ovarian cancer from 2013 to 2022.

Objective: As one of the cancers that seriously threatens women's health, ovarian cancer has a high morbidity and mortality rate. Surgery and chemotherapy are the basic treatment strategies for ovarian cancer, and chemotherapy resistance is a significant factor in affecting the prognosis, survival cycle, and recurrence of ovarian cancer. This article aims to analyze articles about ovarian cancer and drug resistance via bibliometric software, offering new ideas and directions for researchers in this field.

Efficacy comparison of immune treating strategies for NSCLC patients with negative PD-L1 expression.

Background: We intended to compare and grade the proposed immune treating strategies for non-small cell lung cancer (NSCLC) with negative Programmed Cell Death Ligand 1(PD-L1).

Methods: We compared the efficacy of single immune checkpoint inhibitor (ICI), single ICI plus chemotherapy, and doublet ICIs with chemotherapy alone, as well as single ICI plus radiotherapy with single ICI for negative PD-L1 (<1%) NSCLC patients. Hazard Ratio (HR) and 95% confidence interval (CI) of progression-free survival (PFS) and overall survival (OS) were used as outcomes.

The addition of oral iron improves chemotherapy-induced anemia in patients receiving erythropoiesis-stimulating agents.

Although many studies have shown that supplementation with iron and erythropoiesis-stimulating agents (ESA) is frequently used for managing chemotherapy-induced anemia (CIA), optimal combination therapy using these agents together to ameliorate anemia is not well characterized. To assess the effects of ESA combined with oral or intravenous (IV) iron on relieving CIA, PubMed, Cochrane Library, Embase and China National Knowledge Infrastructure (CNKI) were searched for articles. Data collected in the articles were meta-analyzed using RevMan 5.
