Effectiveness of low-load resistance training with blood flow restriction vs. conventional high-intensity resistance training in older people diagnosed with sarcopenia: a randomized controlled trial.

Low-load resistance training with blood flow restriction (LRT-BFR) has shown potential to improve muscle strength and mass in different populations; however, there remains limited evidence in sarcopenic people diagnosed with sarcopenia criteria. This study systematically compared the effectiveness of LRT-BFR and conventional high-intensity resistance training (CRT) on clinical muscle outcomes (muscle mass, strength and performance), cardiovascular disease (CVD) risk factors and sarcopenia-related biomarkers of older people with sarcopenia. Twenty-one older individuals (aged 65 years and older) diagnosed with sarcopenia were randomly assigned to the LRT-BFR (20%-30% one-repetition maximum (1RM), n = 10) or CRT (60%-70% 1RM, n = 11) group.

Oxygenate-induced structural evolution of high-entropy electrocatalysts for multifunctional alcohol electrooxidation integrated with hydrogen production.

High-entropy compounds have been emerging as promising candidates for electrolysis, yet their controllable electrosynthesis strategy remains a formidable challenge because of the ambiguous ionic interaction and codeposition mechanism. Herein, we report a oxygenates directionally induced electrodeposition strategy to construct high-entropy materials with amorphous features, on which the structural evolution from high-entropy phosphide to oxide is confirmed by introducing vanadate, thus realizing the simultaneous optimization of composition and structure. The representative P-CoNiMnWVO shows excellent bifunctional catalytic performance toward alkaline hydrogen evolution reaction and ethanol oxidation reaction (EOR), with small potentials of -168 mV and 1.

Power evolution prediction of bidirectional Raman amplified WDM system based on PINN.

We propose using physical-informed neural network (PINN) for power evolution prediction in bidirectional Raman amplified WDM systems with Rayleigh backscattering (RBS). Unlike models based on data-driven machine learning, PINN can be effectively trained without preparing a large amount of data in advance and can learn the potential rules of power evolution. Compared to previous applications of PINN in power prediction, our model considers bidirectional Raman pumping and RBS, which is more practical.

Effectiveness of non-pharmacological traditional Chinese medicine combined with conventional therapy in treating fibromyalgia: a systematic review and meta-analysis.

Objective: Fibromyalgia is a chronic musculoskeletal disorder characterized by generalized pain, which is also known as "muscular rheumatism" in Chinese medicine. We undertook this systematic review to evaluate the effectiveness of non-pharmacological traditional Chinese medicine (TCM) combined with conventional therapy on pain, health status, depression, and the quality of life of fibromyalgia patients.

Methods: Studies were retrieved from five electronic databases (PubMed, the Cumulative Index to Nursing and Allied Health, Cochrane Library, Embase, and Web of Science) with publication date up to August 2022.

Multiple idiopathic cervical root resorption: A systematic review.

The current literature on multiple idiopathic cervical root resorption (MICRR), a rare and aggressive form of external root resorption, is limited to case reports and series. Therefore, we performed a systematic review of this condition. A comprehensive search of PubMed, Embase, Web of science, Cochrane Library, CNKI, and WANFANG was conducted using key terms relevant to MICRR, supplemented by a grey literature search.

[Determination of Pb in import ginseng by microwave-digestion graphite-furnace atomic absorption spectrometry].

The determination of lead in import ginseng was studied, where microwave assimilation offers a quick, safe and accurate approach with little pollution compared to conventional methods. In the measurements graphite-furnace atomic absorption spectrometry (GFAAS) was used with the advantages of high sensitivity, high speed and little wastage. The microwave assimilation was programed, the mixed acid was analyzed, the problem of the effect of final assimilating liquid on the inspection results was solved, and the inspection conditions of GFAAS were studied.
