Fortunately, constructing organic-inorganic hybrids of molecular catalysts and semiconductors can tackle the above problems, which can improve the efficiency of charge separation and keep beneficial active sites simultaneously.

Pharmacological efficacy study of the cardio-cerebral stasis transforming medicines on cerebral ischemia and myocardial infarction in rats.

The purpose of this study was to investigate the efficacy and mechanisms of cardio-cerebral stasis transforming medicines (CCSTM) against cerebral infarction (CI) and myocardial infarction (MI). CI modeling was conducted using the refined Longa suture-occluded technique, while MI modeling was accomplished through the occlusion of the anterior descending branch of the left coronary artery. We found that compared with the model groups, CCSTM decreased the infarct size in models of CI and MI in a dose-dependent manner.

Pathogenesis and Key Cells in Allergic Rhinitis.

Background: Allergic rhinitis (AR) is one of the most common chronic diseases worldwide, with prevalence rates as high as 50% in high-income countries. Patients with AR often have symptoms such as runny nose, itchy nose, nasal congestion, sneezing, and signs of edema and pallor of the nasal mucosa, and these pathologies have a major impact on the patient's learning, sleep, and quality of life, often resulting in significant pain and a huge economic burden for the patient.

Summary: Among the current treatments for AR, immunotherapy is able to achieve satisfactory clinical outcomes.

Chrysomycin A Reshapes Metabolism and Increases Oxidative Stress to Hinder Glioblastoma Progression.

Glioblastoma represents the predominant and a highly aggressive primary neoplasm of the central nervous system that has an abnormal metabolism. Our previous study showed that chrysomycin A (Chr-A) curbed glioblastoma progression in vitro and in vivo. However, whether Chr-A could inhibit orthotopic glioblastoma and how it reshapes metabolism are still unclear.

Comparison of outcomes of incremental vs. standard peritoneal dialysis: a systematic review and meta-analysis.

Background: Incremental peritoneal dialysis (IPD) refers to the use of less than standard full-dose peritoneal dialysis (SPD) in end-stage renal disease patients. While the use of IPD is being reported in the literature, its safety and efficacy vs. SPD is unclear.

Meis1 Targets Protein Tyrosine Phosphatase Receptor J in Fibroblast to Retard Chronic Kidney Disease Progression.

Renal fibrosis is a common pathological feature of chronic kidney disease (CKD) with the proliferation and activation of myofibroblasts being definite effectors and drivers. Here, increased expression of Meis1 (myeloid ecotropic viral integration site 1) is observed, predominantly in the nucleus of the kidney of CKD patients and mice, and negatively correlates with serum creatinine. Fibroblast-specific knock-in of Meis1 inhibits myofibroblast activation and attenuates renal fibrosis and kidney dysfunction in CKD models.

A tumour-associated macrophage-based signature for deciphering prognosis and immunotherapy response in prostate cancer.

For the multistage progression of prostate cancer (PCa) and resistance to immunotherapy, tumour-associated macrophage is an essential contributor. Although immunotherapy is an important and promising treatment modality for cancer, most patients with PCa are not responsive towards it. In addition to exploring new therapeutic targets, it is imperative to identify highly immunotherapy-sensitive individuals.
