Mechanisms of the effect of gut microbes on depression through the microbiota-gut-brain axis.

Depression is a significant public health issue which exerts profound psychological and social impacts on both individuals and society. However, existing therapeutic strategies often exhibit limited efficacy. Accumulating evidence underscores the vital role of gut microbiota in the pathophysiology of depression through the microbiota-gut-brain (MGB) axis.

Physiological responses and transcriptomic analysis of gene overexpression in potato under salt stresses.

Introduction: The potato ( L.), one of the most vital food crops worldwide, is sensitive to salinity. Brassinosteroids (BRs) are crucial in tolerance to various abiotic stresses.

The impact of task complexity and translating self-efficacy belief on students' translation performance: Evidence from process and product data.

Previous studies that explored the impact of task-related variables on translation performance focused on task complexity but reported inconsistent findings. This study shows that, to understand the effect of task complexity on translation process and its end product, performance in translation tasks of various complexity levels needs to be compared in a specific setting, in which more factors are considered besides task complexity-especially students' translating self-efficacy belief (TSEB). Data obtained from screen recording, subjective rating, semi-structured interview, and quality evaluation were triangulated to measure how task complexity influenced the translation performance of Chinese students with high and low TSEB.

Comprehensive Analysis of Gene Family and Its Expression in Response to Different Abiotic Stresses in Potato.

As a highly conserved family of plant-specific proteins, SIMILAR-TO-RCD-ONE (SROs) play an essential role in plant growth, development and response to abiotic stresses. In this study, six genes were identified by searching the PARP, RST and WWE domains based on the genome-wide data of potato database DM v6.1, and they were named - according to their locations on chromosomes.

Functional analysis of StDWF4 gene in response to salt stress in potato.

The DWARF4 (DWF4) gene encodes a C-22 hydroxylase which is pivotal for brassinosteroids (BRs) biosynthesis. In this research, aimed to understand the molecular mechanism of DWF4 on regulation of potatoes tolerance to salt stress, DWF4 was cloned from potato, named as StDWF4. Its 1476 bp open reading frame encodes a protein of 491 amino acids.

Expression of the Galanthus nivalis agglutinin (GNA) gene in transgenic potato plants confers resistance to aphids.

Aphids, the largest group of sap-sucking pests, cause significant yield losses in agricultural crops worldwide every year. The massive use of pesticides to combat this pest causes severe damage to the environment, putting in risk the human health. In this study, transgenic potato plants expressing Galanthus nivalis agglutinin (GNA) gene were developed using CaMV 35S and ST-LS1 promoters generating six transgenic lines (35S1-35S3 and ST1-ST3 corresponding to the first and second promoter, respectively).

Isolation and characterization of StERF transcription factor genes from potato (Solanum tuberosum L.).

Ethylene response factor (ERF) is a major subfamily of the AP2/ERF family and plays significant roles in the regulation of abiotic- and biotic-stress responses. ERF proteins can interact with the GCC-box cis-element and then initiate a transcriptional cascade activating downstream ethylene response and enhancing plant stress tolerance. In this research, we cloned five StERF genes from potato (Solanum tuberosum L.

A quantitative study of the intracellular concentration of graphene/noble metal nanoparticle composites and their cytotoxicity.

Noble-metal nanoparticles (NPs) especially prepared from gold and silver have been combined on the surface of graphene to obtain graphene-based nanocomposites for novel functions in enhanced performance in bio-imaging, cancer detection and therapy. However, little is known about their cellular uptake, especially the intracellular quantity which plays a critical role in determining their functions and safety. Therefore, we prepared covalently conjugated GO/Au and GO/Ag composites by immobilizing Au and Ag nanoparticles on GO sheets pre-functionalized with disulfide bonds, respectively.

Influence of structure and properties of colloidal biomaterials on cellular uptake and cell functions.

The molecular structure and physicochemical properties of nano- and colloidal materials have a big impact on their intracellular uptake and cell functions. Elucidation of the cellular uptake and cytotoxicity of the colloidal materials has been recognized recently as one of the paramount prerequisites for their biomedical applications. In this review, the influence of important parameters of colloidal biomaterials such as size, shape, chemical and mechanical properties on cellular uptake and its pathways is summarized.

Uptake of cerium oxide nanoparticles and their influences on functions of A549 cells.

The cerium oxide nanoparticles (NPs) have been widely used in the fields of fuel additives, cosmetics, commodities, pharmaceuticals and other industries. Exposure of the CeO2 NPs causes a public concern on their potential health risk. In this study, the interactions between two commercial CeO2 NPs and human bronchoalveolar carcinoma-derived A549 cells were investigated to provide a fast and in-depth understanding of the biological influences of the NPs.

Influence of surface coating of PLGA particles on the internalization and functions of human endothelial cells.

This study is focused on the uptake of PLGA particles with different coatings and its influences on the functions and toxicity of human endothelial cells. The PLGA particles coated with polyethyleneimine (PEI) or bovine serum albumin (BSA) were prepared via a one-step emulsion method, which had a similar diameter of ∼420 nm in water and ∼170 nm in a dry state but oppositely charged surfaces. Both types of the particles were readily internalized into cells within a short time regardless of their surface chemistry.

[Hemostatic effect of hemocoagulase agkistrodon and its mechanism].

This study was aimed to investigate the hemostatic effects of hemocoagulase agkistrodon (HCA) and its mechanism. The procoagulative and hemostatic effects of HCA were evaluated by using rabbit blood coagulatin time and mouse tail bleeding time; the mechanisms of HCA hemostatic effect were analyzed by using rabbit blood clot lysis and fibrinogen lysis. The results showed that HCA shortened the rabbit blood coagulation time and the mouse tail bleeding time significantly.
