College students' disciplinary expertise and their entrepreneurial intentions: an exploratory study based on foreign language majors with experience in innovation and entrepreneurship training programs.

Taking foreign language majors with experience in innovation and entrepreneurship training program (IETP) as samples, this study investigates the influence of disciplinary expertise on entrepreneurial intention. Based on the theory of planned behavior (TPB), a model was designed to examine the relationships among entrepreneurial intentions, perceived behavioral control, attitude toward entrepreneurship, subjective norms, IETP experience, foreign language self-efficacy and cultural intelligence. The data were collected through questionnaires and Partial least squares structural equation modeling (PLS-SEM) was adopted to test the hypotheses.

Microbial Community Structure and Metabolism of Xinjiang Fine-Wool Sheep based on High-Throughput Sequencing Technology.

It turns out that the more than trillion microorganisms living in the host's digestive tract are crucial for maintaining nutrient intake, environmental suitability, and physiological mechanism. Xinjiang fine-wool sheep is an exclusive breed for wool in China, which has excellent stress tolerance. In this study, we collected feces and blood samples of 20 Xinjiang fine-wool sheep under the same genetic characteristics, the Fine-Wool Sheep (FWS) group and the Control Fine-Wool Sheep (CFWS) group were set up according to the differs in phenotypic characteristics of their wool.

BSA-stabilized silver nanoclusters for efficient photoresponsive colorimetric detection of chromium(VI).

Hexavalent chromium is a highly toxic substance, which will pose a serious threat to human life and health and the entire ecosystem. Therefore, it is crucial to establish a simple and rapid detection method for hexavalent chromium. In this work, we fabricated bovine serum albumin-stabilized silver nanocluster (BSA-Ag NC) which exhibited photoresponsive oxidase-like activity, catalyzing the oxidation of colorless 3,3',5,5'-tetramethylbenzidine (TMB) to the blue oxidized state TMB (oxTMB) in a short time.

Platinum nanoparticles confined in metal-organic frameworks as excellent peroxidase-like nanozymes for detection of uric acid.

High levels of uric acid (UA) in humans can cause a range of diseases, and traditional assays that rely on uric acid enzymes to break down uric acid are limited by the inherent deficiencies of natural enzymes. Fortunately, the rapid development of nanozymes in recent years is expected to solve the above-mentioned problems. Hence, we used a host-guest strategy to synthesize a platinum nanoparticle confined in a metal-organic framework (Pt NPs@ZIF) that can sensitively detect UA levels in human serum.

The research framework of cross-cultural adaptation is constructed, and four hypotheses are put forward, and 100 venture entrepreneurs in multinational enterprises are randomly recruited and investigated through the QS (Questionnaire Survey) design. Finally, the results are analyzed through statistical software.

lncRNA SNHG22 sponges miR‑128‑3p to promote the progression of colorectal cancer by upregulating E2F3.

The long non‑coding RNA (lncRNA) small nucleolar RNA host gene 22 (SNHG22) has been reported as a crucial regulator in several types of human cancer. The present study evaluated the function and mechanism of SNHG22 in colorectal cancer (CRC) progression. SNHG22 expression was detected in colorectal adenoma, CRC tumor tissues (TTs) and adjacent non‑cancerous tissues (ANTs) using reverse transcription‑quantitative PCR (RT‑qPCR).

An untargeted metabolomics approach to identify markers to distinguish duck eggs that come from different poultry breeding systems by ultra high performance liquid chromatography-high resolution mass spectrometry.

Untargeted metabolomics approach based on ultra high performance liquid chromatography coupled with high resolution mass spectrometry (UHPLC-HRMS) was used to investigate the differences in cage duck eggs and sea duck eggs that from different poultry breeding system, which could help to combat fraud within the egg industry. High dimensions and complex data collected by UHPLC-HRMS were analyzed by multivariate statistical analysis. Identification model of sea duck eggs based on was established.

A strategy for the determination of flavor substances in goat milk by liquid chromatography-high resolution mass spectrometry.

A new analytical method for untargeted screening of flavor compounds in goat milk and milk flavor using mass spectrometry was developed and validated. All compounds of low molecular weight were considered as candidate chemicals, instead of focusing only on compounds that already have a known affect on the flavor quality of goat milk. High performance liquid chromatography coupled with high resolution quadrupole orbitrap mass spectrometry based on external standard was used to analyse flavor compounds in complex samples.

Discrimination of Milk from Different Animal Species by a Foodomics Approach Based on High-Resolution Mass Spectrometry.

An untargeted foodomics strategy based on ultra-high-performance liquid chromatography coupled with quadrupole orbitrap and chemometrics was used to observe subtle differences in the molecule profiles of raw milk from different animal species (cow milk, goat milk, and water buffalo milk), which could prevent the fraud activities in the dairy industry. In data-dependent acquisition (DIA), spectra for all precursor ions facilitated the comprehensive identification of unknown compounds in untargeted foodomics. Chemometrics techniques were used to analyze large amounts of complex data to observe the separation of different sample groups and find the potential markers of sample groups.

Association between matrix Gla protein and ulcerative colitis according to DNA microarray data.

Background: Matrix Gla protein (MGP) is a secreted protein contributed to the immunomodulatory functions of mesenchymal stromal cells. Microarray profiling found a significantly higher expression level of the extracellular matrix gene MGP in patients with ulcerative colitis (UC). However, little is known about the role of MGP in UC and its upstream signaling regulation.

[Determination of 20 -blockers and metabolites in animal-origin foods by ultra performance liquid chromatography-quadrupole electrostatic field orbitrap mass spectrometry].

In this study, ultra performance liquid chromatography-quadrupole electrostatic field orbitrap mass spectrometry was used to establish a high-throughput screening method for 20 -blockers and their metabolites in foods of animal origin. The sensitivity and applicability of the established method were improved by optimizing the instrument and pretreatment conditions. The samples were purified by high speed centrifugation at low temperature, and the compounds were separated by a C8 column.

[Advances in markers reflecting technological conditions in the liquid milk processing].

The trade volume of imported dairy products is increasing with the increase of per capita consumption of dairy products, thus it is the great significant thing to control the quality of dairy products from other countries. The investigation finds that the proline content of imported liquid milk ultra high temperature instantaneous sterilization (UHT) milk (commonly known as normal temperature milk) is significantly higher than that of domestic UHT milk, that a risk of overheating and adding reconstituted milk exists for the imported UHT milk. Although it is currently unable to regulate the source and processing technology of imported dairy products, some certain indicators that reflect the process conditions are often used to monitor the quality of dairy products in the field of heat treatment process control of dairy products.
