Enhanced density separation efficiency of microplastics in presence of nonionic surfactants.

Microplastics (MPs) recycling, a promising approach to tackle its pollution, faces significant challenges due to the lack of effective separation methods. Herein, the optimized density separation accompanied with nonionic surfactants was employed to purify single MPs species from mixed systems. By adjusting the flotation fluid density, the single MPs can be separated from their mixtures in equal proportions (e.

Injectable body temperature responsive hydrogel for encephalitis treatment via sustained release of nano-anti-inflammatory agents.

Skull defects are common in the clinical practice of neurosurgery, and they are easily complicated by encephalitis, which seriously threatens the life and health safety of patients. The treatment of encephalitis is not only to save the patient but also to benefit the society. Based on the advantages of injectable hydrogels such as minimally invasive surgery, self-adaptation to irregularly shaped defects, and easy loading and delivery of nanomedicines, an injectable hydrogel that can be crosslinked in situ at the ambient temperature of the brain for the treatment of encephalitis caused by cranial defects is developed.

A meta-analysis of dietary inhibitors for reducing methane emissions via modulating rumen microbiota in ruminants.

Background: Rumen methane emissions (RME) significantly contribute to global greenhouse gas emissions, underscoring the essentials to identify effective inhibitors for RME mitigation. Despite various inhibitors shown potential in reducing RME by modulating rumen microbes, their impacts include considerable variations and inconsistency.

Objective: We aimed to quantitively assess the impacts of various methane inhibitors on RME, rumen microbial abundance and fermentation in ruminants.

Development and validation of a risk prediction model for dyslipidemia in community-dwelling middle-aged and older adults in China: a nationwide survey.

Background: The incidence of dyslipidemia as a risk factor for many serious diseases is increasing year by year. This study aimed to construct and visualize a risk prediction model for dyslipidemia in middle-aged and older adults.

Method: The subjects of our study are derived from CHARLS.

Phase I study of [Ga]Ga-HX01 for targeting integrin αvβ3 and CD13 in healthy and malignancy subjects.

Purpose: Noninvasive angiogenesis visualization is essential for evaluating tumor proliferation, progression, invasion, and metastasis. This study aimed to translate the heterodimeric PET tracer [Ga]Ga-HX01, which targets integrin αvβ3 and CD13 in neovascularization, into phase I clinical study.

Methods: This study enrolled 12 healthy volunteers (phase Ia) and 10 patients with malignant tumors (phase Ib).
