Characterization of gelatin-based composite films loaded with polysaccharide and carbon dots from Stropharia rugosoannulata and their application in pork fresh-keeping.

In this study, bio-based composite films with enhanced barrier, mechanical, antioxidant and antimicrobial properties were prepared by incorporating Stropharia rugosoannulata waste (SP)-derived polysaccharides (SPP) and carbon dots (SPCDs) as an active substance into gelatin (GEL) matrix, which were evaluated for their potential application in pork preservation. The effects of varying concentrations of SPCDs on the morphology, microstructure, and overall performance of the films were systematically investigated. The findings demonstrated that the addition of SPCDs to the GEL/SPP matrix significantly improved the mechanical strength, water vapor permeability, and ultraviolet light blocking ability of the composite films.

Low-temperature on-site in situ high-pressure ultrafast pump-probe spectroscopy instrument.

We design and construct an ultrafast optical spectroscopy instrument that integrates both on-site in situ high-pressure technique and low-temperature tuning capability. Conventional related instruments rely on off-site tuning and calibration of the high pressure. Recently, we have developed an on-site in situ technique, which has the advantage of removing repositioning fluctuation.

Hypomagnesemia is a risk factor for acute kidney injury in patients admitted with ST-segment elevation myocardial infarction: A retrospective observational study.

Background: Acute kidney injury (AKI) is prevalent in patients hospitalized with ST-segment elevation myocardial infarction (STEMI) and is correlated with worse cardiovascular outcomes. Hypomagnesemia has been found to be associated with an elevated risk of AKI in various patient populations. Nonetheless, the relationship between hypomagnesemia and AKI incidence in patients with STEMI has not been fully elucidated.

Molecular Hydride Superconductor BiH with up to 91 K at 170 GPa.

In pursuit of high- hydride superconductors, the molecular hydrides have attracted less attention because the hydrogen quasimolecules are usually inactive for superconductivity. Here, we report on the successful synthesis of a novel bismuth hydride superconductor 2/-BiH at pressures around 170-180 GPa. Its structure comprises bismuth atoms and elongated hydrogen molecules with a H-H bond length of 0.

The clinical significance of the Neutrophil-to-Lymphocyte Ratio as a novel inflammatory biomarker for assessing the severity of intervertebral disc degeneration.

Purpose: Inflammation is integral to the pathogenesis of intervertebral disc degeneration, yet the role of systemic inflammatory markers in this process remains underexplored. This study aims to explore the association between the Neutrophil-to-Lymphocyte Ratio (NLR) and the severity of disc degeneration.

Patients And Methods: A retrospective analysis was conducted on 375 patients diagnosed with lumbar disc degeneration between April 2018 and May 2021.
