Impact of Polystyrene Microplastics on Soil Properties, Microbial Diversity and L. Growth in Meadow Soils.

The pervasive presence of microplastics (MPs) in agroecosystems poses a significant threat to soil health and plant growth. This study investigates the effects of varying concentrations and sizes of polystyrene microplastics (PS-MPs) on the L.'s height, dry weight, antioxidant enzyme activities, soil physicochemical properties, and rhizosphere microbial communities.

A Novel Exopolysaccharide Produced by sp. MT01 and Its Potential Application in Enhanced Oil Recovery.

Sphingan is a crucial exopolysaccharide (EPS) produced by genus bacteria with wide-ranging applications in fields such as food, medicine, and petroleum. In this study, a novel sphingan, named MT gum, was overproduced from the wild-type strain sp. MT01 at a yield of 25.

Mitogenome Phylogenetics of Spiruromorpha Porpoise Parasite: Insights Into Phylogeny of .

(1) Background: is a major parasite of large porpoises and whales and has been classified in the Habronematoidea family. However, there has been a great controversy regarding its classification. Mitochondria have an important function in revealing taxonomic and evolutionary history.

Grazing-Induced Habitat Degradation: Challenges to Giant Panda Survival Resulting from Declining Bamboo and Soil Quality.

Grazing is the primary human-induced disturbance affecting giant panda () habitats and has a severe impact on the long-term sustainability of the giant panda population. To address the lack of quantitative studies on grazing's impact on habitat quality, we selected China's most heavily grazed giant panda nature reserve. Utilizing the Maxent model and stoichiometric analysis, we investigated habitat quality degradation caused by grazing and quantified changes in bamboo nutritional quality and soil physicochemical properties.

Abietic Acid Alleviates the Hypoxic Injury of Cardiomyocytes by Adjusting Autophagy and Apoptosis Mediated by miR-30a-5p/GRP78 Axis.

Objective: To explore the influence of abietic acid on the autophagy and apoptosis of cardiomyocytes in rats with acute myocardial infarction (AMI).

Methods: A rat model of AMI was built by ligation of the anterior descending branch of left coronary artery, and a model of hypoxic cardiomyocyte injury was constructed by treating cardiomyocytes with hypoxia. Western blot assay was used to detect the abundance of proteins related to autophagy and apoptosis, MTT assay was used to measure the viability of cardiomyocytes, and the expression level of miR-30a-5p was detected by qRT-PCR.
