Analysis of growth physiological changes and metabolome of highland barley seedlings under cadmium (II) stress.

This study aims to investigate the physiological changes in growth and metabolic response mechanisms of highland barley under different concentrations of cadmium. To achieve this, cadmium stress was applied to green barley at levels of 20, 40, and 80 mg/L. The results revealed that, under Cd(II) stress, the chlorophyll content and photosynthesis in leaves of highland barley seedlings were inhibited to some extent.

A Bifunctional "Two-in-One" Array for Simultaneous Diagnosis of Irritable Bowel Syndrome and Identification of Low-FODMAP Diets.

Irritable bowel syndrome (IBS) is a globally prevalent functional gastrointestinal disorder frequently misdiagnosed due to overlapping symptoms with other diseases. Currently, there are no rapid and effective diagnostic or therapeutic approaches for IBS. Despite this, low-FODMAP diets (LFDs) have become a major dietary intervention strategy for symptom relief.

Effects of polystyrene microplastics on the growth and metabolism of highland barley seedlings based on LC-MS.

Microplastics are widely present in the environment and can adversely affect plants. In this paper, the effects of different concentrations of microplastics on physiological indices and metabolites of highland barley were investigated for the first time using a metabolomics approach, and revealed the response mechanism of barley seedlings to polystyrene microplastics (PS-MPs) was revealed. The results showed that the aboveground biomass of highland barley exposed to low (10 mg/L) and medium (50 mg/L) concentrations of PS-MPs increased by 32.

Trust in family doctor-patient relations: an embeddedness theory perspective.

Background: Based on the embeddedness theory, the present study aims to explore the association between patients' trust in family doctors (Interpersonal Trust), trust in community health centers (Organizational Trust), and trust in society as a whole (Social Trust).

Methods: A cross-sectional survey was conducted in six community health centers in China, using partial least squares structural equation modeling to assess trust scale reliability and validity while testing hypotheses.

Results: The scores of Interpersonal Trust, Organizational Trust, and Social Trust were 3.

Soil Microplastic Pollution and Microbial Breeding Techniques for Green Degradation: A Review.

Microplastics (MPs), found in many places around the world, are thought to be more detrimental than other forms of plastics. At present, physical, chemical, and biological methods are being used to break down MPs. Compared with physical and chemical methods, biodegradation methods have been extensively studied by scholars because of their advantages of greenness and sustainability.

Peptides Used for Heavy Metal Remediation: A Promising Approach.

In recent years, heavy metal pollution has become increasingly prominent, severely damaging ecosystems and biodiversity, and posing a serious threat to human health. However, the results of current methods for heavy metal restoration are not satisfactory, so it is urgent to find a new and effective method. Peptides are the units that make up proteins, with small molecular weights and strong biological activities.

The Easily Overlooked Effect of Global Warming: Diffusion of Heavy Metals.

Since industrialization, global temperatures have continued to rise. Human activities have resulted in heavy metals being freed from their original, fixed locations. Because of global warming, glaciers are melting, carbon dioxide concentrations are increasing, weather patterns are shifting, and various environmental forces are at play, resulting in the movement of heavy metals and alteration of their forms.

Impact of Vanadium-Titanium-Magnetite Mining Activities on Endophytic Bacterial Communities and Functions in the Root Systems of Local Plants.

This study utilized 16S rRNA high-throughput sequencing technology to analyze the community structure and function of endophytic bacteria within the roots of three plant species in the vanadium-titanium-magnetite (VTM) mining area. The findings indicated that mining activities of VTM led to a notable decrease in both the biodiversity and abundance of endophytic bacteria within the root systems of and ( < 0.05).

The Diversity and Community Composition of Three Plants' Rhizosphere Fungi in Kaolin Mining Areas.

Mining activities in the kaolin mining area have led to the disruption of the ecological health of the mining area and nearby soils, but the effects on the fungal communities in the rhizosphere soils of the plants are not clear. Three common plants (, , and ) in kaolin mining areas were selected and analyzed their rhizosphere soil fungal communities using ITS sequencing. The alpha diversity indices (Chao1, Shannon, Simpson, observed-species, pielou-e) of the fungal communities decreased to different extents in different plants compared to the non-kauri mining area.

Intraspecific and interspecific variations in the synonymous codon usage in mitochondrial genomes of 8 pleurotus strains.

In this study, we investigated the codon bias of twelve mitochondrial core protein coding genes (PCGs) in eight Pleurotus strains, two of which are from the same species. The results revealed that the codons of all Pleurotus strains had a preference for ending in A/T. Furthermore, the correlation between codon base compositions and codon adaptation index (CAI), codon bias index (CBI) and frequency of optimal codons (FOP) indices was also detected, implying the influence of base composition on codon bias.

Multilocus Distance-Regulated Sensor Array for Recognition of Polyphenols via Machine Learning and Indicator Displacement Assay.

Developing new strategies to construct sensor arrays that can effectively distinguish multiple natural components with similar structures in mixtures is an exceptionally challenging task. Here, we propose a new multilocus distance-modulated indicator displacement assay (IDA) strategy for constructing a sensor array, incorporating machine learning optimization to identify polyphenols. An 8-element array, comprising two fluorophores and their six dynamic covalent complexes () formed by pairing two fluorophores with three distinct distance-regulated quenchers, has been constructed.

Effects of polystyrene microplastics on the agronomic traits and rhizosphere soil microbial community of highland barley.

This study investigated the influence of polystyrene microplastics (MPs) with two different particle sizes (<1 mm, 1-5 mm) and three concentrations (1 g/m, 10 g/m, 50 g/m), as well as added degrading bacteria, on the agronomic traits of highland barley and the bacterial communities in the rhizosphere soil. Results revealed that the small particle size treatment had a significant effect on reducing the 1000-grain weight of highland barley, while the large particle size treatment had an effect on reducing the spike length, width, and awn length (P < 0.05).
