Therapeutic Efficacy of a Synthetic Brain-Targeted HS Donor Cross-Linked Nanomicelle in Autism Spectrum Disorder Rats through Aerobic Glycolysis.

Autism spectrum disorder (ASD) is characterized by cognitive inflexibility and social deficits, with a notably limited range of brain-targeted medications, particularly in the field of nanomedicine. Herein, we introduce the brain-targeted HS donor cross-linked nanomicelle, named mannose-PEG600-lipoic acid (Man-LA). Man-LA demonstrates enhanced stability and precise brain delivery by interacting with glucose transporter 1 (GLUT1) in astrocytes, facilitating a gradual release of HS that is modulated by glutathione (GSH).

Exploring the decision-making experience of elderly diabetes patients regarding their health-seeking behaviour: a descriptive qualitative study.

Background: Diabetes has emerged as a critical global public health issue. The burden of diabetes is escalating in developing countries, including China. For individuals with diabetes, making informed and rational decisions regarding health-seeking behaviour is crucial to prevent or delay the occurrence of complications.

Erythrophagocytosis-induced ferroptosis contributes to pulmonary microvascular thrombosis and thrombotic vascular remodeling in pulmonary arterial hypertension.

Background: Whether primary or just as a complication from the progression of pulmonary arterial hypertension (PAH), thrombosis seems to be an important player in this condition. The crosstalk between red blood cells (RBCs) and pulmonary microvascular endothelial cells (PMVECs) and their role in PAH remain undefined.

Objectives: The goals of this study were to assess the role of RBC-PMVEC interaction in microvascular thrombosis and thrombotic vascular remodeling under hypoxic conditions.

CircSSR1 regulates pyroptosis of pulmonary artery smooth muscle cells through parental protein SSR1 mediating endoplasmic reticulum stress.

Introduction: Pyroptosis, inflammatory necrosis of cells, is a programmed cell death involved in the pathological process of diseases. Endoplasmic reticulum stress (ERS), as a protective stress response of cell, decreases the unfold protein concentration to inhibit the unfold protein agglutination. Whereas the relationship between endoplasmic reticulum stress and pyroptosis in pulmonary hypertension (PH) remain unknown.

Methyltransferase-Like 3-Mediated N6-Methyladenosine RNA Methylation Regulates Hypoxia-Induced Pulmonary Arterial Smooth Muscle Cell Pyroptosis by Targeting PTEN.

Background: Pulmonary hypertension is a rare, progressive disorder that can lead to right ventricular hypertrophy, right heart failure, and even sudden death. N6-methyladenosine modification and the main methyltransferase that mediates it, methyltransferase-like (METTL) 3, exert important effects on many biological and pathophysiological processes. However, the role of METTL3 in pyroptosis remains unclear.
