Article Abstract
This paper concentrates on a simple and robust control method for the discrete time nonlinear systems to fulfill the requirement of predefined accuracy. A sliding mode control method is designed by introducing equivalent dynamic linearization technique according to the input/output (I/O) information merely. A square-root type error transformation method is presented for the tracking error to be restricted within a preassigned zone. The performance of presented control method is demonstrated through experiments on a nonlinear system. Experiment results show that the presented control method has a superior tracking accuracy compared with PID controller and model-free adaptive control (MFAC).

Background: The aim of this study was to establish a rat model of premature ovarian failure (POF) with cyclophosphamide (CTX), and explore the molecular basis of POF and the mechanism of Guishen-Erxian Decoction (GSEXD) to improve POF from the perspective of oxidative stress regulation of ovarian granulosa cell (OGC) DNA fragmentation.
Method: The study utilized SD rats to establish a POF model via CTX. Rats were divided into Control, POF group, three GSEXD dosage groups (low, medium, high), and a GSEXD+PI3K agonist group to assess GSEXD's therapeutic effects on oxidative stress, DNA fragmentation and ovarian damage.

Background: Atherosclerosis is a chronic inflammatory disease characterized by the accumulation of lipid-laden foam cells and plaques within the arterial wall. Dysfunctional vascular smooth muscle cells (VSMCs), fibroblasts, endothelial cells, and macrophages contribute to disease progression. Here, we report that macrophage-specific expression of epsins, highly conserved endocytic adaptor proteins involved in clathrin-mediated endocytosis, accelerates atherosclerosis in Western diet-fed mice.

Immune checkpoint therapy has demonstrated significant potential in the treatment of various solid tumors. Among these, tumor-induced immunosuppression mediated by programmed cell death protein 1 (PD-1) represents a critical checkpoint. PD-1/programmed death-ligand 1 (PD-L1) inhibitors have been proven to exhibit substantial efficacy in solid tumors such as melanoma and bladder cancer.

Background: The association between season of screening blood pressure (BP) measurement and adverse outcomes has not been examined among populations without prior physician-diagnosed hypertension. We aimed to investigate the association between the season of screening clinic BP measurement and the risk of all-cause mortality.
Methods: This was a prospective cohort study, and data were analyzed from an ongoing community hypertension screening program in Shanghai between 2018 and 2024.

Introduction: Anxiety and stress are prevalent mental health issues. Traditional drug treatments often come with unwanted side effects and may not produce the desired results. As an alternative, probiotics are being used as a treatment option due to their lack of specific side effects.
