Professional Commitment of 8-Year Medical Doctoral Degree Program Students in China: The Mediating Role of Self-Efficacy, Learning Engagement, and Academic Performance.

Background: Studying the professional commitment of a student in an 8-year medical training program of China, especially its association with academic performance, can enhance the understanding of professional loyalty in future doctors. This study aimed to investigate the self-efficacy, academic performance, professional commitment, and learning engagement of 8-year program medical students, and explore the mediating roles of professional commitment and learning engagement on the associations between self-efficacy and academic performance.

Methods: We conducted a cross-sectional study in a Chinese medical university and collected the General Self-Efficacy Scale, Professional Commitment of Undergraduates Scales, and the Utrecht Work Engagement Scale-Student from self-reported students.

Cube is a good form: Hyperspectral band selection via multi-dimensional and high-order structure preserved clustering.

As an effective strategy for reducing the noisy and redundant information for hyperspectral imagery (HSI), hyperspectral band selection intends to select a subset of original hyperspectral bands, which boosts the subsequent different tasks. In this paper, we introduce a multi-dimensional high-order structure preserved clustering method for hyperspectral band selection, referred to as MHSPC briefly. By regarding original hyperspectral images as a tensor cube, we apply the tensor CP (CANDECOMP/PARAFAC) decomposition on it to exploit the multi-dimensional structural information as well as generate a low-dimensional latent feature representation.

UHPLC-MS/MS-based central carbon metabolism unveils the biomarkers related to colon cancer.

Even though colon cancer ranks among the leading causes of cancer mortality, early detection dramatically increases survival rates. Many studies have been conducted to determine whether altered metabolite levels may serve as a potential biomarker of cancer that affects key metabolic pathways. The goal of the study was to detect metabolic biomarkers in patients with colon cancer using liquid chromatography-mass spectrometry (LC-MS).

Wastewater treatment and emerging contaminants: Bibliometric analysis.

In recent years, emerging contaminants have been found in the wastewater, surface water, and even drinking water, which should be treated to ensure the safety of our living environment. In this study, we provide a comprehensive summary of wastewater treatment and emerging contaminants research from 1998 to 2021 by using the bibliometric analysis. This study is conducted based on the Web of Science Core Collection Database.

Preparation, characterization, and bioactivity evaluation of oligosaccharides from Atractylodes lancea (Thunb.) DC.

Sixteen oligosaccharide monomers with the degree of polymerization 3 to 18 (DP 3 to DP 18) and three active fractions (DP 3-9, DP 8-11, and DP 11-17) were separated from Atractylodes lancea (Thunb.) DC. by optimized fast protein liquid chromatography coupled with refractive index detector (FPLC-RID) and preparation hydrophilic interaction chromatography (Pre-HILIC).

Oligosaccharide-based quality evaluation of Atractylodis rhizome and a strategy for simplifying its quality control.

Background: Atractylodis rhizoma, is the dried rhizomes of (Thunb.) DC. or (DC.

Structural characterization and immunoregulatory activity of two polysaccharides from the rhizomes of Atractylodes lancea (Thunb.) DC.

A neutral polysaccharide (ALP-1) and an acidic polysaccharide (ALP-3) were purified from Atractylodes lancea (Thunb.) DC. ALP-1 exhibited a linear backbone composed of (2 → 1)-linked β-d-fructofuranose.

Application of RNA interference methodology to investigate and develop SCMV resistance in maize.

Specific fragments of the sugarcane mosaic virus (SCMV) coat protein gene (cp) were amplified by reverse transcriptionpolymerase chain reaction and used to construct a marker free small interfering RNA complex expression vector against SCMV. In planta transformation was performed on maize (Zea mays) inbred line 8112 mediated by Agrobacterium tumefaciens. PCR and Southern blot analyses demonstrated successful integration of the cp segment into the 8112 genome.

Identification and expression analysis of primary auxin-responsive Aux/IAA gene family in cucumber (Cucumis sativus).

Aux/IAA is an important gene family involved in many aspects of growth and development. Aux/IAA proteins are short-lived nuclear proteins that are induced primarily by various phytohormones. In this study, 29 Aux/IAA family genes (CsIAA01-CsIAA29) were identified and characterized in cucumber, including gene structures, phylogenetic relationships, conserved protein motifs and chromosomal locations.
