45% to 50.4%) of hydrolytic and SCFAs-forming bacteria.The purpose of this research was to explore the effects of red mud on cellulose degradation and the succession of β-glucosidase microbial community in composting to better enhance the quality of compost. The activity of β-glucosidase in the treatment group with red mud (T) was 0.42-1.07 times higher than that in the control group without red mud (CK) from day 7 to 21 of composting. The final cellulose degradation ratios of the T (84.73%) were 10.02% higher than that of the CK (74.71%). In addition, Proteobacteria, Actinobacteria, Firmicutes, and Ascomycota were the most dominant β-glucosidase-producing microbes, and these microbes were also the phyla causing composting performances differences in the high temperature, cooling, and maturity periods of CK and T. These results indicated that adding red mud can improve β-glucosidase activity and boost the breakdown of cellulose in composting process.3-Hydroxyarginine (3-OH-Arg) is an important intermediate for the synthesis of viomycin, an important antibiotic for the clinical treatment of tuberculosis. An efficient strategy for 3-OH-Arg production based on protein engineering and recombinant whole-cell biocatalysis was demonstrated for the first time. To avoid challenging product separation due to the generation of α-ketoglutarate (α-KG) in the system, the molar ratio of the substrates L-Arg and L-Glu was optimized to ensure the efficient production of 3-OH-Arg as well as the complete consumption of α-KG. Through the establishment of a fed-batch process, 3-OH-Arg and succinic acid (SA) production reached to 9.9 g/L and 5.98 g/L after 36 h of reaction under the optimized conditions. SB-743921 mouse This is the highest biosynthetic yield of 3-OH-Arg achieved to date, potentially offering a promising strategy for commercial production of hydroxylated amino acids.

To observe isolated lumbopelvic-hip complex (LPHC) stability and muscle activity using the Seated Trunk Control Test (STCT) and evaluate the relationship between LPHC stability and 2-dimensional kinematics during movements.

Descriptive Study.

Laboratory.

22 healthy participants (12F, 10M, 23.5±3.1yrs, 173.0±9.0cm, 76.1±10.7kg).

Time to first error and number of errors, and muscle activity of the abdominals, erector spinae, and gluteus medius were recorded during the STCT. Lateral trunk movement, hip and knee frontal plane projection angles, hip and knee flexion during single leg squats and single leg drop vertical jumps were measured. Pearson r correlations were calculated among STCT performance, muscle activity, and 2-dimensional kinematics.

Number of errors was moderately correlated to hip and knee flexion during single leg squatting (r=0.456-0.649, p<0.05). Number of errors and time to first error were moderately correlated to knee-frontal plane projection angle and hip flexion respectively during single leg drop vertical jumping (r=0.463-0.515, p<0.05).

Decreased LPHC stability relates to decreased sagittal plane motion during single leg squatting and increased frontal plane motion during single leg drop vertical jumping. Pairing the STCT with 2-dimensional kinematic analysis can demonstrate influence of LPHC function.

To determine whether back foot (BF) position influences dorsiflexion range of motion (DFROM) during three different positions of the weight bearing lunge test (WBLT).

Randomised, repeated measures design.

Sports clubs.

52 athletes participating in cutting and pivoting sports.

DFROM was obtained using a WBLT in three different BF positions BF heel in full contact with the floor, BF heel raised off the floor and BF was non weight bearing (NWB). All measurements were obtained using three methods inclinometer at the tibial tuberosity, toe to wall distance and goniometer angle from the lateral malleolus to the fibula head. Differences between testing positions were determined using a repeated measures one-way ANOVA and reliability analysis was performed using the Intraclass Correlation Coefficient (ICC).

DFROM was statistically significantly different for all three positions of the WBLT for each measurement technique (P<.001). These results were associated with large effect sizes for all BF positions and measurement techniques. Reliability ICC values were excellent for all measurements (ICC 0.94-0.99).

Results show that DFROM differs depending upon the position of the BF during the WBLT. Further research is needed to establish the reproducibility of these three BF positions due to the variability observed.

Virtual-reality simulation (VRS) is an innovative teaching method in nursing education. However, information regarding the educational elements that should be included in the associated instructional design, and the technology necessary for its optimal implementation, is limited.

To develop an effective template for VRS-based nursing education, and to evaluate its usability.

A methodological study.

Multimedia room in university.

Sixteen undergraduate nursing students.

First, we developed a template, which was validated by content experts. The template was then modified based on the experts' feedback, and was then applied in three VRS scenarios.

The developed template consisted of educational elements, virtual elements, and scenario outlines. The educational elements were learning target, learning objectives, instructional design, course flow, feedback strategies, follow-up and evaluation, debriefing structures, and human resources. The virtual elements were virtual framework, degree of virtuality, and virtual resources. The scenario outline included scenario target, learning objectives, evaluation, course flow, associated knowledge and skill, setting, scenario background, protocols, nursing intervention, algorithm and storyboard, documentation forms, mechanical supports, scenario characters, accessory items, and debriefing components. Three VRS scenarios were developed using this template. Students in focus group interviews described their learning experience.

The template can help educators administer effective VRS-based nursing education; however, the technical level of the platform used should be considered.
