[Analysis of phthalate esters and their novel alternatives in indoor dust using comprehensive two-dimensional gas chromatography-time of flight mass spectrometry].

A comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC×GC-TOF-MS) method was developed to analyze 25 traditional phthalate esters (PAEs) and 19 novel alternatives in indoor dust samples. PAEs are ubiquitous in indoor environments because they are widely used as plasticizers in a variety of consumer products, and potential health concerns have prompted the need for effective monitoring methods. In this study, dust samples were collected from various indoor settings in a university campus, including classrooms, cafeterias, laboratories, and dormitories, and were subsequently ultrasonically extracted with hexane-dichloromethane (1∶1, v/v) solution for 30 min.

Resveratrol Reduces Cisplatin-induced Cochlear Hair Cell Pyroptosis by Inhibiting the mtROS/TXNIP/NLRP3 Pathway.

Background: Cisplatin is an effective anti-cancer drug with limited clinical applications due to ototoxicity. Resveratrol, known for its antioxidant and anti-inflammatory properties, has been reported to mitigate these adverse effects, although the underlying mechanism remains under-researched.

Objective: This study aimed to investigate the effects and underlying mechanisms of resveratrol on cisplatin-induced ototoxicity.

Chromosome-level genome assembly of tetraploid Chinese cherry (Prunus pseudocerasus).

Chinese cherry belongs to the family Rosaceae, genus Prunus, and has high nutritional and economic value. 'Duiying' is a Chinese cherry variety local to Beijing, and has better performance than sweet cherry in terms of disease resistance. However, disease resistance resources of 'Duiying' have not been fully exploited partially due to the lack of a high-quality genome.

Disruption of midgut homeostasis by microplastics in Spodoptera frugiperda: Insights into inflammatory and oxidative mechanisms.

Microplastics have evolved as widespread contaminants in terrestrial and aquatic environments, raising significant environmental concerns due to their persistence and bioaccumulation. In this study, we investigated the toxicity of polyethylene microplastics (PE-MPs) on the agricultural insect, Spodoptera frugiperda. Maize leaves containing three sizes (0.
