Objective To investigate the effects of high-definition transcranial direct current stimulation (HD-tDCS) on the modulation of the H-reflex and M-wave during ankle dorsiflexion-plantar flexion fatigue tasks to provide direction for the application of HD-tDCS in mitigating neuromuscular fatigue. Methods Twenty healthy young male participants were recruited and randomly assigned to either the real stimulation or sham stimulation group, with 10 participants in each group. The intervention consisted of a 5-day single-blind HD-tDCS application (duration: 20 min; intensity: 2 mA; target: Cz) . Baseline measurements of the H-reflex and M-wave under resting conditions, M-wave during maximal voluntary isometric contraction (MVIC) of the dorsiflexor muscle, and MVIC torque of the dorsiflexor and plantar flexor muscles were obtained. An ankle dorsiflexion fatigue task was performed to determine the time to achieve fatigue for the task. The same fatigue task was repeated and evaluated one day after the intervention. A repeated-measures two-factor (stimulation condition × pre / post fatigue) analysis of variance (ANOVA) was used to analyze the effects of independent variables on the mechanical properties of the muscles and α-motoneuron conduction characteristics. Results After fatigue, voluntary activation (VA), maximal H-reflex (Hmax ), maximal M-wave (Mmax ), and dorsiflexor and plantar flexor MVIC torques in both groups were significantly reduced compared with pre-fatigue levels (P junction under the ankle dorsi-plantarflexion fatigue task. © 2024 Editorial Department of journal of Shanghai Second Medical University.

The novel cyclic phosphate-phosphqnates,cis/trans-2-phosp dimethyl-1,3,2-dioxaphosphorinane 2-sulfides(selenides) (7a-f),were synthesized by a one-pot reaction using tris(diethviamino)phosphine activated by iodine as the phosphorylating and ring-closing reagent in good overall yields. The geometric stereoisomers were isolated and characterized. A cis-configuration and a chair preferred conformation of one isomer of 7b were established by X-ray diffraction analysis.

Suppose that P=(p\-1, p\-2, ..., p\-M)\% is a probability vector with p\-i>0 and Y={1, 2, ..., M}. Let (Y, 2\+Y, μ) be a probability space with μ(i)=p\-i, i=1, 2, ..., M, and (∑\-M, B, m)= Π \+∞\-0(Y, 2\+U, μ). It is shown that for any a \%(0≤a ≤1) \%, there exists a set U∈B such that m(U)=a and the julia set associated with U is equal to the julia set associated with ∑\-M\%. Moreover repelling fixed points with respect to U are dense in the julia set associated with U.

In acid medium, sparfloxacin is oxidized by nitrous acid, then reacts with hydrobromic acid to form a new fluorescence substance, which can emit the strong fluorescence. which is 151 fold more than that of sparfloxacin itself. By this, a new sensitive method for the determination of sparfloxacin in human urine by derivative-synchronous fluorescence is presented with good results.

The superτ-charm facility(STCF)is an electron–positron collider proposed by the Chinese particle physics community.It is designed to operate in a center-of-mass energy range from 2 to 7 GeV with a peak luminosity of 0.5×10^(35) cm^(–2)·s^(–1) or higher.The STCF will produce a data sample about a factor of 100 larger than that of the presentτ-charm factory—the BEPCII,providing a unique platform for exploring the asymmetry of matter-antimatter(charge-parity violation),in-depth studies of the internal structure of hadrons and the nature of non-perturbative strong interactions,as well as searching for exotic hadrons and physics beyond the Standard Model.The STCF project in China is under development with an extensive R&D program.This document presents the physics opportunities at the STCF,describes conceptual designs of the STCF detector system,and discusses future plans for detector R&D and physics case studies.

In the previous papers, we reported the structural elucidation of stellarins A-E, five new cyclopeptides from the fresh roots of Stellaria yunnanensis Franch. Further chemical study on this plant led to the isolation of two other new cyclopeptide named stellarins F(1) and G(2). By a combination of 2D-NMR, enzymatic degradation and FABMS, their structures were established to by cyclo(Gly-Ala-Gly-Ser-Pro-Trp-Phe-Pro) and cyclo(Gly-Ala-Tyr-Leu-Ala), respectively.
