Toxicity and intergenerational accumulation effect of tire wear particles and their leachate on Brachionus plicatilis.

Tire wear particles (TWP) are one of the main sources of microplastic (MP) pollution in the marine environment, causing adverse effects on marine life and attracting increasing attention. This study aimed to investigate the chemical composition of TWP (particles and leachate) and their toxic effects on Brachionus plicatilis. The results showed that Zn and acenaphthene were the most frequently detected compounds in the three TWP treatments.

Maternal exposure to polystyrene nanoplastics during gestation and lactation caused fertility decline in female mouse offspring.

The impact of micro/nano plastics (MPs/NPs) on human health is a significant area of research. Studies on the effects of maternal exposure to microplastics (MPs) on the fertility in offspring have been conducted, but the damage caused by nanoplastics (NPs) remains ambiguous. In this study, pregnant Kunming mice were exposed to 30 mg/kg/day PS-NPs from 0.

MGB probe-based multiplex droplet digital PCR for the interspecific identification of Notopterygii Rhizoma et Radix in herbal materials and preparations.

Background: Owing to high sensitivity and ability for absolute quantification, the droplet digital polymerase chain reaction (ddPCR) is widely used for viral and bacterial detection. However, few studies have been conducted on the application of ddPCR to identify the original plant species used in traditional Chinese medicine and Chinese patent medicine.

Purpose: In this study, we investigated the feasibility of using ddPCR to differentiate between Notopterygium incisum and N.

Spatial distribution and driving factors of soil selenium on the Leizhou Peninsula, southern China.

Selenium (Se) is an essential element for humans, playing a critical role in the functioning of the immune system. The global prevalence of dietary Se deficiency is a significant public health concern, largely attributed to the low levels of Se present in crops. The sufficient Se in plants and humans is determined by the presence of stable Se sources in the soil.

Transcranial resection of falcine meningiomas by complete endoscopy with the assistance of intraoperative ultrasound.

Transcranial neurosurgery assisted by endoscopy and intraoperative ultrasound (IOUS) has become an effective approach for real-time visualization and guidance during tumor resection. This study explores the application of these techniques in falcine meningioma (FM) resection, assessing their feasibility and safety. Eleven FM patients underwent transcranial endoscopic resection with IOUS assistance.
