Background Hypertrophic scarring is an abnormal condition involving excessive fibroblast activation, aberrant extracellular matrix deposition, and persistent inflammation. Current treatments have limited efficacy and potential adverse effects, necessitating the development of new approaches. Purpose In this study, we investigated the effects of artesunate (ART) on hypertrophic scar (HS) formation and explored the underlying cellular and molecular mechanisms.

However, its efficiency is limited in wet age-related macular degeneration (wet AMD) due to choroidal neovascularization (CNV). To investigate the feasibility of hESC-RPE cell transplantation, we employed a surgical approach to induce retinal detachment, which allowed the removal of CNV lesions.

Introduction: Policy reforms in drug regulation and reimbursement have encouraged drug research and development in China. However, there is a lack of insights on industry trends for dermatology research. We aim to describe trends and features of clinical trials for dermatology drugs in China, understand recent achievements, and forecast development trends.

SVZ cells play important roles in neurological diseases like neurodegeneration, neural injury, and glioblastoma multiforme. Investigating the anatomy, structure, composition, physiology, disease associations, and related mechanisms of SVZ is significant for neural stem cell therapy and treatment/prevention of neurological disorders.

We explored effects of HT on Wnt -catenin and other pathways involved in cancer stem cell renewal, DNA repair, cell proliferation, and differentiation. Twenty-five milligrams per day oral dose of HT was given for 12 months in pre- and postmenopausal women at increased risk of breast cancer.

Methods: Carbomer 940 and α-pinene were used as model thickening agent and antifungal, respectively. A series of α-pinene NGs (αNG1, αNG2, αNG3) containing 0.
Nonalcoholic fatty liver disease (NAFLD) is a metabolic liver disorder with severe complications. Mitochondrial dysfunction due to over-opening of the mitochondrial permeability transition pore (mPTP) in liver cells plays a central role in the development and progression of NAFLD. Restoring mitochondrial function is a promising strategy for NAFLD therapy.

TNSs were introduced into the PDA/CNT composite, which effectively averted the agglomeration of the CNT and further exposed more adsorption sites. PDA thin layer exposing more active sites was conducive to enhance adsorption capacity and kinetic.

Uncontrolled bacterial infection leads to excessive production of reactive oxygen species (ROS) and persistent inflammatory responses, which seriously hinder conventional physiological healing processes after injury. Biofilms, as protective barriers for bacteria, pose a critical obstacle to effective bacterial eradication.

Currently, most orthopedic robots are in the early stages of development, and evaluating their clinical efficacy can assist in making informed decisions for practical use.
Objective: To explore the advantages of 7 types of robot-assisted THA with respect to 5 indicators.
Introduction: Whether double filtration plasmapheresis (DFPP) is effective in the patients who do not response to the initial immunotherapy is uncertain. This retrospective study aimed to evaluate the efficacy and safety of DFPP in the treatment of patients who had no improvement after initial immunotherapy (steroids and/or immunoglobulin (IVIG)), and moreover, to investigate the factors associated with the efficacy of DFPP.
Methods: From January 1st, 2014, to December 30th,2018, a total of 26 patients who were diagnosed autoimmune encephalitis (AE) and were received the treatment of DFPP after unsuccessful or incomplete recovery from their early immune therapy (including intravenous high-dose cortisone, IVIG and or immunosuppressant) for at least 21 days were investigated.

Accumulating evidence has revealed that chronic unresolved inflammation can cause significant tissue damage and can be a key mediator of advanced heart failure (HF). Resolvin (Rv) D2, a member of specialized pro-resolving lipid mediators (SPMs), plays a protective role in various diseases by facilitating resolution. However, whether RvD2 participates in the pathogenesis of HF is still unclear.

Organic cocrystals formed through multicomponent self-assembly have attracted significant interest owing to their clear structure and tunable optical properties. However, most cocrystal systems suffer from inefficient long-wavelength emission and low phosphorescence efficiency due to strong non-radiative processes governed by the energy gap law. Herein, an efficient long-lived red afterglow is achieved using a pyrene (Py) cocrystal system incorporating a second component (NPYC4) with thermally activated delayed fluorescence (TADF) and ultralong organic phosphorescence (UOP) properties.

Background: Membranous nephropathy (MN) has not yet been fully elucidated regarding its relationship with Type I and II Diabetes. This study aims to evaluate the causal effect of multiple types of diabetes and MN by summarizing the evidence from the Mendelian randomization (MR) study.
Methods: The statistical data for MN was obtained from a GWAS study encompassing 7979 individuals.
The high nitrogen content and diverse reactivity of malononitrile are widely harnessed to access nitrogen-rich fine chemicals. Although the facile substitutions of malononitrile can give structurally diverse quaternary carbons, their access to enantioenriched molecules, particularly chiral amines that are prevalent in bioactive compounds, remains rare. Here we report a cobalt-catalysed desymmetric reduction of disubstituted malononitriles to give highly functionalized β-quaternary amines.
