Ultrasound elastography predicts anticoagulation in lower extremity deep vein thrombosis.

Objective: To investigate predictors of anticoagulation efficacy in deep venous thrombosis (DVT) by ultrasound elastography (UE).

Methods: The basic clinical, laboratory and ultrasound treatment data of fifty-eight patients with DVT were collected and analyzed. Then the results of ultrasound after 3-month anticoagulation treatment were compared among different groups.

siRNA Silencing of FpVtg Induces Ovarian Cell Apoptosis in Redtail Prawn, Fenneropenaeus penicillatus.

Inadequate gonadal maturation and poor spawning performance increasingly threaten the sustainability of shrimp aquaculture. Unraveling the mechanisms regulating ovarian development and maturation hence is critical to address industry challenges. Vitellogenin (Vtg), a precursor of yolk protein found in the hepatopancreas and ovary of shrimp, plays a key role in facilitating shrimp's oocyte maturation and embryonic development after oviposition.

Investigating the Impact of the Community of Inquiry Presence on Online Learning Satisfaction: A Chinese College Student Perspective.

Purpose: This study investigated how teaching, social, and cognitive presence within the community of inquiry (CoI) framework impacts Chinese college students' online learning satisfaction through self-regulated learning and emotional states.

Methods: A total of 2608 Chinese college students from 112 universities completed a 38-item Likert scale survey measuring teaching, social and cognitive presence, self-regulated learning, emotional states, and online learning satisfaction after COVID-19 restrictions were lifted on December 7, 2022. The study examined the influence of teaching, social, and cognitive presence on online learning satisfaction, mediated by self-regulated learning and moderated by emotional states using SmartPLS.

Preparation of Mn-Fe Oxide by a Hydrolysis-Driven Redox Method and Its Application in Formaldehyde Oxidation.

Homogeneous distribution of Mn-Fe oxides (Mn1Fe) with different Mn/Fe ratios was synthesized by a hydrolysis-driven redox method, and their catalytic activities in HCHO oxidation were investigated. The results showed that HCHO conversion was significantly improved after doping iron due to the synergistic effect between manganese and iron. The 5Mn1Fe catalyst exhibits excellent catalytic activity, achieving >90% HCHO conversion at 80 °C and nearly 100% conversion at 100 °C.

A Real-Time, Automatic, and Dynamic Scheduling and Control System for PET Patients Based on Wearable Sensors.

Positron emission tomography (PET) is one of the commonly used scanning techniques. Medical staff manually calculate the estimated scan time for each PET device. However, the number of PET scanning devices is small, the number of patients is large, and there are many changes including rescanning requirements, which makes it very error-prone, puts pressure on staff, and causes trouble for patients and their families.
