Development and validation of a nomogram for predicting postoperative fever after endoscopic submucosal dissection for colorectal lesions.

Fever is a complication after colorectal endoscopic submucosal dissection (ESD). The objective of this study was to explore the incidence and risk factors of fever after colorectal ESD and establish a predictive nomogram model. This retrospective analysis encompassed patients with colorectal lesions who underwent ESD between June 2008 and December 2021 in our center.

On-site biosignal amplification using a single high-spin conjugated polymer.

On-site or in-sensor biosignal transduction and amplification can offer several benefits such as improved signal quality, reduced redundant data transmission, and enhanced system integration. Ambipolar organic electrochemical transistors (OECTs) are promising for this purpose due to their high transconductance, low operating voltage, biocompatibility, and suitability for miniaturized amplifier design. However, limitations in material performance and stability have hindered their application in biosignal amplification.

Transformation mechanism, kinetics and ecotoxicity of kaempferol and quercetin in the gaseous and aqueous phases: A theoretical combined experimental study.

The transformation and risk assessment of flavonoids triggered by free radicals deserve extensive attention. In this work, the degradation mechanisms, kinetics, and ecotoxicity of kaempferol and quercetin mediated by ∙OH, ∙OCH, ∙OOH, and O in gaseous and aqueous environments were investigated using cell experiments and quantum chemical calculations. Three radical scavenging mechanisms, including hydrogen atom transfer (HAT), radical adduct formation (RAF) and single electron transfer (SET) were discussed.

Learning environment as a predictor for medical students' empathy: a multicenter cross-sectional study from 12 medical schools in China.

Background: Empathy of medical students is crucial, yet it tends to decline as students enter later academic years. Empathy appeared to be affected by the learning environment (LE), which could be a potential contributor. We conducted a cross-sectional study to investigate the association between LE and empathy.

Uncovering metabolite changes of potato Fusarium sambucinum infection based on a UPLC-Q-TOF metabonomic approach.

Fusarium sambucinum causes dry rot disease and postharvest storage losses in potatoes. Understanding the defense mechanisms of potato plants may lead to the development of rational disease control approaches. In the present study, "Kexin one" potato variety was infected with F.
