Variation of Ferroptosis-Related Markers in HaCaT Cell Photoaging Models Induced by UVB.

Objective: To investigate the variation of ferroptosis-related markers in HaCaT cell photoaging models induced by ultraviolet-B (UVB).

Methods: UVB-treated HaCaT cells served as the model (UVB group) for cellular photoaging, whereas untreated HaCaT cells served as the control group. HaCaT cells were exposed to UVB and the ferroptosis inhibitor Ferrostatin-1 (Fer-1) as part of the UVB+Fer-1 group, and co-cultured with the ferroptosis inducer Erastin as part of the UVB+Erastin group.

Mechanism of Ba Zhen Tang Delaying Skin Photoaging Based on Network Pharmacology and Molecular Docking.

Purpose: To study the efficacy of Ba Zhen Tang in delaying skin photoaging and its potential mechanism based on network pharmacology and molecular docking.

Methods: First, we screened the active components and targets of Ba Zhen Tang by Traditional Chinese Medicine Database and Analysis Platform (TCMSP) and The Universal Protein Resource (UniProt). The target genes of skin photoaging were obtained from GeneCards and GeneMap database.

A network pharmacology-based study of the potential targets and mechanisms of action of Qibao Meiran Dan in delaying skin aging.

Objective: The aim of this study was to use network pharmacology to explore the potential targets and mechanisms of action of Qibao Meiran Dan in relation to delaying skin aging.

Methods: The traditional Chinese medicine systems pharmacology database and analysis platform, and the traditional Chinese medicine integrated database, were used to screen the active ingredients and targets of Qibao Meiran Dan. The human gene database GeneCards and the gene database of the National Center for Biotechnology Information were jointly adopted to obtain skin aging-related target genes.

Artesunate treatment ameliorates ultraviolet irradiation-driven skin photoaging via increasing β-catenin expression.

Objective: Artesunate, a semi-synthetic derivative of artemisinin, exerts various pharmacological activities. Nevertheless, the effects of Art on skin photoaging remain unclear. Herein, we investigated whether Art ameliorated ultraviolet-irradiated skin photoaging in HaCaT cells and mice.

Anxiety and related factors in frontline clinical nurses fighting COVID-19 in Wuhan.

The aim of this study was to examine the anxiety status of the frontline clinical nurses in the designated hospitals for the treatment of coronavirus disease 2019 (COVID-19) in Wuhan and to analyze the influencing factors, to provide data for psychologic nursing.This study used a cross-sectional survey design and convenience sampling. The questionnaires were completed by 176 frontline clinical nurses.
