The association between marathon running and high-sensitivity cardiac troponin: A systematic review and meta-analysis.

Background: Marathon running is an extreme sport with a distance of about 42 kilometers. Its relationship to high-sensitivity cardiac troponin (hs-cTn) remains controversial.

Objective: As the gold standard for detecting myocardial injury, the trends of hs-cTn before and after a marathon were investigated and analyzed.

CT-based morphological study of the pelvis in patients with gluteal muscle contracture.

Background: In the clinic, gluteal muscle contracture (GMC) causes pelvic structural changes, including acetabular retroversion. However, its causes and forms are not well understood. This study aimed to investigate and analyse the clinical significance of pelvic structural differences between GMC patients and healthy individuals.

Silver doped-silica nanoparticles reinforced poly (ethylene glycol) diacrylate/hyaluronic acid hydrogel dressings for synergistically accelerating bacterial-infected wound healing.

Various cutaneous wounds are easily infected with external bacteria, which might result in a chronic wound and ongoing consequences. However, the appropriate development of biomaterials for the controllable delivery of antibacterial silver (Ag) and the simultaneous enhancement of mechanical adhesiveness remains an urgent challenge. Herein, we proposed a double network (DN) hydrogel dressings based on a covalent network of polyethylene glycol diacrylate (PEGDA) and a coordination network between catechol-modified hyaluronic acid (C-HA) and Ag-doped mesoporous silica nanoparticle (AMSN) for promoting the bacterial-infected full-thickness skin wound regeneration.

Design of FOPID Controller for Pneumatic Control Valve Based on Improved BBO Algorithm.

Aiming at the problems of nonlinearity and inaccuracy in the model of the pneumatic control valve position in the industrial control process, a valve position control method based on a fractional-order PID controller is proposed. The working principle of the pneumatic control valve is analyzed, and its mathematical model is established. In order to improve the accuracy of the model, an improved biogeography-based optimization algorithm is proposed to tune the parameters of the fractional-order PID controller in view of the wide range and high complexity of the fractional-order PID controller.

Common Pathogens and Drug Resistance of Neonatal Pneumonia with New Multichannel Sensor.

This study aimed to study the application value of a new multichannel sensor in pathogen detection and drug resistance analysis of neonatal pneumonia. 180 newborns with infectious pneumonia were selected, and a new multichannel piezoelectric sensor was constructed. The traditional Kirby-Bauer (K-B) method and the piezoelectric sensor were adopted to detect the pathogens and drug resistance in newborn samples, respectively.

Multifunctional injectable hydrogel for effective promotion of cartilage regeneration and protection against osteoarthritis: combined chondroinductive, antioxidative and anti-inflammatory strategy.

The regeneration of the articular cartilage defects is characterized by the improvement in the quality of the repaired tissue and the reduction in the potential development of perifocal osteoarthritis (OA). Usually, the injection of dexamethasone (Dex) in the OA joints slows down the progression of inflammation and relieves pain. However, the anti-inflammatory Dex injected in the joint cavity is rapidly cleared, leading to a poor therapeutic effect.

Clinical effect of different maintenance doses of caffeine citrate in the treatment of preterm infants requiring assisted ventilation: a pilot multicenter study.

Objectives: To explore the optimal maintenance dose of caffeine citrate for preterm infants requiring assisted ventilation and caffeine citrate treatment.

Methods: A retrospective analysis was performed on the medical data of 566 preterm infants (gestational age ≤34 weeks) who were treated and required assisted ventilation and caffeine citrate treatment in the neonatal intensive care unit of 30 tertiary hospitals in Jiangsu Province of China between January 1 and December 31, 2019. The 405 preterm infants receiving high-dose (10 mg/kg per day) caffeine citrate after a loading dose of 20 mg/kg within 24 hours after birth were enrolled as the high-dose group.

Spinal-pelvic sagittal parameters in patients with gluteal muscle contracture: an imaging study.

Background: Gluteal muscle contracture (GMC) may cause abnormal spinal alignment as well as hip and pelvic deformities. The spine-pelvis alignment of GMC patients is unclear. This study aimed to describe the spine-pelvis sagittal alignment in patients with GMC and to explore the impact of GMC on the pathogenesis of low back pain (LBP).

A novel magnesium ion-incorporating dual-crosslinked hydrogel to improve bone scaffold-mediated osteogenesis and angiogenesis.

Osteogenesis is closely complemented by angiogenesis during the bone regeneration process. The development of functional hydrogel bone substitutes that mimic the extracellular matrix is a promising strategy for bone tissue engineering. However, the development of scaffold materials tailored to exhibit sufficient biomechanics, biodegradability, and favorable osteogenic and angiogenic activity continue to present a great challenge.

The effect of running on knee joint cartilage: A systematic review and meta-analysis.

Objective: Although running causes inevitable stress to the joints, data regarding its effect on the cartilage of the knee are conflicting. This systematic review and meta-analysis aimed to evaluate the effect of running on knee joint cartilage.

Methods: PubMed, EMBASE, SportDiscus, and Cochrane Library databases were searched to identify randomized controlled trials (RCTs) and cohort studies.

The impact of nutritional quality and gut bacteria on the fitness of (Diptera: Tephritidae).

To examine how nutritional quality and resident gut bacteria interplay in improving the fitness of an oligophagous fruit fly, , artificial sucrose diets and full diets (sucrose, tryptone and yeast extract) were fed to flies with and without antibiotic supplementation. Furthermore, and were supplemented to sucrose-only diets. Flies were maintained in the laboratory and the fitness parameters, male and female longevity, number of copulations and female fecundity, were recorded.
