Unidirectional moisture-conducting green fabrics prepared by a one-step electrospray technique.

Unidirectional moisture-conducting fabrics were prepared by electrospraying polyvinylidene fluoride (PVDF) and polyvinyl chloride (PVC) onto three green fabric substrates, namely cotton, hemp, and modal. Experiments were conducted to examine the effects of coating thickness, coating material, and substrate material on the moisture conductivity of the fabrics. The electrospraying technique was effective in forming uniform and strongly adhered PVDF and PVC coatings on the fabric substrates, and the coating thickness and material type had a significant effect on the fabric's moisture conductivity.

Study on the Dynamic Fracture Properties of Defective Basalt Fiber Concrete Materials Under a Freeze-Thaw Environment.

This study examines the crack resistance of basalt-fiber-reinforced concrete (BFRC) materials subjected to freeze-thaw cycles (FTCs). We utilized a φ50 mm Split Hopkinson Pressure Bar (SHPB) apparatus alongside numerical simulations to carry out impact compression tests at a velocity of 5 m/s on BFRC specimens that experienced 0, 10, 20, and 30 FTCs. Additionally, we investigated the effects of basalt fiber (BF) orientation position and length on stress intensity factors.

Computer-Aided High Tibial Osteotomy-A Comparative Study of Commonly Used 3D Printing Technology and Navigation Application.

Background: High tibial osteotomy (HTO) is a surgical procedure for treating certain knee conditions. Proper execution of HTO can preserve joint function and delay or avoid the need for total knee replacement. This study compared different 3D printing techniques (fused deposition modeling, selective laser sintering, and direct metal laser sintering) and a navigation system for their suitability in assisting HTO surgeries.

Beta oscillation modulations of the orienting attention network effect correlate with dopamine-dependent motor symptoms of Parkinson's disease.

Attention impairment, a prevalent non-motor symptom in Parkinson's disease (PD), plays a crucial role in movement disorders. PD patients exhibit abnormalities in the attentional network related to alerting, orienting, and executive control. While dopamine medications have well-documented effects on motor function, their impact on attention networks and the underlying neural mechanisms involved in motor functions remain unclear.

Procalcitonin-guided use of antibiotic in hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease: a randomized clinical trial.

Objectives: The objectives of this study are to analyse the effect and safety of procalcitonin (PCT)-guided antibiotic therapy in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

Methods: We conducted a multicentre, open-label, randomized controlled trial amongst patients hospitalized for AECOPD in six hospitals in China. Enrolled patients were randomly assigned to either the PCT-guided group or the Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy-guided group.
