Innovative integration of the "W + Flipped Classroom" and "B + BOPPPS" teaching models for enhanced learning outcomes.

Background: With the demand for more effective and engaging teaching strategies in higher education, there is an imperative to blend traditional and innovative methods to optimize student learning outcomes. To address this educational need, this study sets out to design and evaluate a hybrid learning approach that integrates a flipped classroom based on working process systematization (termed "W + flipped classroom") teaching design with blended online and offline methods based on the BOPPPS (bridge-in, objective/outcome, preassessment, participatory learning, post assessment, summary, termed "B + BOPPPS") teaching model and explore its application effects in the field of biological separation engineering.

Methods: The undergraduate class of 2020 majoring in biomedical engineering from Huanghuai University was designated the control group (n = 74), while the undergraduate class of 2021 was chosen as the experimental group (n = 79).

Research on the application of the blended BOPPPS based on an online and offline mixed teaching model in the course of fermentation engineering in applied universities.

This study aimed to investigate the teaching effect of the blended BOPPPS based on an online and offline mixed teaching model ("B + BOPPPS") in the course of fermentation engineering in applied universities. The participants were 142 undergraduates majoring from the course of fermentation engineering in Food Science and Engineering in 2019 and 2020 in Huanghuai University, Zhumadian city, Henan province, China. The students in the control group (68 students) were taught in 2019, and the students in the experimental group (74 students) were taught in 2020.

Physicochemical, structural and functional properties of protein isolates and major protein fractions from common vetch (Vicia sativa L.).

Common vetch (CV), a leguminous crop cultivated for green manure and fodder rich in protein and starch, is widespread over much area of the northern hemisphere. Its seeds can be used as a protein source to human consumption. CV protein isolates (CVPI) and major protein fractions (CV albumin protein, CVAP; CV globulin protein, CVGP; CV glutelin protein, CVGTP) from 4 samples were investigated the properties to facilitate full use of protein resources.

Efficient Production of Lactic Acid from Sweet Sorghum Juice by a Newly Isolated Lactobacillus salivarius CGMCC 7.75.

Sweet sorghum juice was a cheap and renewable resource, and also a potential carbon source for the fermentation production of lactic acid (LA) by a lactic acid bacterium. One newly isolated strain Lactobacillus salivarius CGMCC 7.75 showed the ability to produce the highest yield and optical purity of LA from sweet sorghum juice.

Polyploidy origin of wheatgrass Douglasdeweya wangii (Triticeae, Poaceae): evidence from nuclear ribosomal DNA internal transcribed spacer and chloroplast trnL-F sequences.

To study hybrid speciation in wheatgrass Douglasdeweya wangii and to investigate the evolutionary pattern of nuclear ribosomal DNA (nrDNA) internal transcribed spacer sequences (ITSs) in allotetraploids, DNA sequence variation of ITSs and chloroplast trnL-F sequences from D. wangii and its putative donors were analyzed. The ITSs revealed that D.

Identification of Elymus (Triticeae, Poaceae) and its related genera genomes by RFLP analysis of PCR-amplified Adh genes.

Elymus L. is the largest genus in Triticeae, containing about 150 species with four recognized genome donors (St, H, P, and W). Traditionally, the genome compound of this genus is identified based on cytological data.

Phylogenetic relationships in Elymus (Poaceae: Triticeae) based on the nuclear ribosomal internal transcribed spacer and chloroplast trnL-F sequences.

To estimate the phylogenetic relationship of polyploid Elymus in Triticeae, nuclear ribosomal internal transcribed spacer (ITS) and chloroplast trnL-F sequences of 45 Elymus accessions containing various genomes were analysed with those of five Pseudoroegneria (St), two Hordeum (H), three Agropyron (P) and two Australopyrum (W) accessions. The ITS sequences revealed a close phylogenetic relationship between the polyploid Elymus and species from the other genera. The ITS and trnL-F trees indicated considerable differentiation of the StY genome species.
