Association of Myasthenia Gravis With Autoimmune Thyroid Disease: A Bidirectional Mendelian Randomization Study.

Background And Purpose: Observational studies have indicated a high occurrence of coexistence between myasthenia gravis (MG) and autoimmune thyroid disease (AITD) in clinical settings, but the causal relationship between the two conditions remains ambiguous. Therefore, this study endeavors to investigate the causal links between MG, along with its subgroups, and AITD through a Mendelian randomization (MR) approach.

Methods: Genetic instrumental variables associated with MG and AITD were selected from three major publicly available GWAS databases for MR analysis.

Regulating the production distribution in Ni-Cu nanoparticle mediated nitrile hydrogenation.

The selective hydrogenation of nitrile compounds represents a pivotal area of research within both industrial and academic catalysis. In this study, we prepared Ni-Cu bimetallic catalysts through a co-deposition-crystallization sequence, aimed at the efficient production of primary and secondary amines. The enhanced selectivity for primary amines is attributed to the downshift of the d-band center of NiCu, which weakens the adsorption of key imine intermediates.

No causal link between herpes zoster and ischemic stroke: evidence from Mendelian randomization study.

Objective: The association between herpes zoster (HZ) and stroke has been the subject of much previous research. Nevertheless, the connection remains ambiguous. A two-sample Mendelian randomisation study was conducted to explore the potential causal link between HZ and ischaemic stroke, including its subtypes.

Membrane-Based Pulsed Sampling Method for Extended Dynamic Range of Ion Mobility Spectrometry.

Ion mobility spectrometry (IMS) has been widely studied and applied as an effective analytical technology for the on-site detection of volatile organic compounds (VOCs). Despite its superior selectivity compared with most gas sensors, its limited dynamic range is regarded as a major drawback, limiting its further application in quantitative measurements. In this work, we proposed a novel sample introduction method based on pulsed membrane adsorption, which effectively enhanced IMS's ability to measure analytes at higher concentrations.

Investigation of the Underlying Mechanism of Huangqi-Dangshen for Myasthenia Gravis Treatment via Molecular Docking and Network Pharmacology.

The herbal pairing of Huangqi and Dangshen (HD) is traditional Chinese herbal medicine and has been widely used in China, especially to treat myasthenia gravis (MG). However, the mechanism of HD on MG is unclear. .

Invigorating spleen, replenishing qi and tonifying kidney method treatment of traditional Chinese medicine for myasthenia gravis: A protocol for systematic review and meta-analysis.

Background: Myasthenia gravis (MG) is an autoimmune disease related to the production of autoantibodies. It is mediated by antibodies against acetylcholine receptor (AChR), muscle specific kinase (MuSK) or other AChR related proteins in the postsynaptic muscle membrane, which interfere with the transmission of signals at the neuromuscular junction, resulting in clinical symptoms of skeletal muscle weakness and fatigue, leading to the occurrence and development of MG. At present, the incidence rate of Mg is increasing year by year.

Exploring the Oxidative Stress Regulation of Mice with Hyperglycemia by Lactiplantibacillus plantarum SCS4.

The aim of this study was to evaluate the effects of Lactiplantibacillus plantarum SCS4 (L. plantarum SCS4) on oxidative stress in streptozocin-induced hyperglycemic mice. After establishment of the hyperglycemic model, control group mice were gavaged daily with phosphate-buffered saline, while different experimental groups (AG, BG, and CG) mice were gavaged with L.

Assembly of 5-dibenzo[,]cycloheptenes by a formal [5 + 2] annulation of -aryl alkynyl benzyl alcohols with arenes.

A new synthetic methodology for the synthesis of 5-dibenzo[,]cycloheptenes from -aryl alkynyl benzyl alcohols and arenes a TfO-mediated formal [5 + 2] annulation reaction has been achieved. From this transformation, structurally diverse 5-dibenzo[,]cycloheptenes were achieved in moderate to good yields. This transformation probably involves an intermolecular Friedel-Crafts-type alkylation and a subsequent intramolecular 7- cyclization in one pot, highlighting the high efficiency, regioselectivity, and step-economy of this protocol.

Understanding Chinese Consumers' Livestreaming Impulsive Buying: An Stimulus-Organism-Response Perspective and the Mediating Role of Emotions and Zhong Yong Tendency.

We built a livestreaming impulsive buying model based on stimulus-organism-response (SOR) theory, and we explored the impact of atmospheric cues (ACELS) and sales promotion (SPELS) on impulsive buying (IBI) based on emotions (EOC) and Zhong Yong tendency (ZYT) of online consumers. Combined with holistic orientation, perspective integration, and harmony maintenance, ZYT is a cognitive process involving individual events. We gathered 478 samples using a questionnaire to test the proposed research model.

Recent advances on micellar catalysis in water.

Water is the universal solvent in nature to catalyze the biological transformation processes. However, owing to the immiscibility of many reagents in water, synthesis chemistry relies heavily on organic solvent. Micellar media is a green alternative to traditional petroleum feedstock derived solvents, which is recently attracting increasing research attention.

On the Origin of the Promoting Effect Exerted by Magnesium in the ZnCl-Catalyzed Synthesis of ,-Diisopropylethylamine.

The reaction of magnesium or zinc amides with alkyl or benzyl halides is an attractive approach to make C-N bonds, especially for electron-poor organic halides. The magnesium-promoted preparation of hindered non-nucleophilic amine (,-diisopropylethylamine) from ethyl chloride and zinc diisopropylamide has been studied. In this paper, instead of the application scope of this method, we focused on the mechanisms of the catalytic processes and the associated electronic origins.

Tape-Casting Li La TiO Ceramic Electrolyte Films Permit High Energy Density of Lithium-Metal Batteries.

Ceramic oxide electrolytes are outstanding due to their excellent thermostability, wide electrochemical stable windows, superior Li-ion conductivity, and high elastic modulus compared to other electrolytes. To achieve high energy density, all-solid-state batteries require thin solid-state electrolytes that are dozens of micrometers thick due to the high density of ceramic electrolytes. Perovskite-type Li La TiO (LLTO) freestanding ceramic electrolyte film with a thickness of 25 µm is prepared by tape-casting.

Efficient Dehydration of C-α,ω-Alkanediols to Alkadienes as Catalyzed by Aliphatic Acids.

The aliphatic-acid-mediated dehydration of C-α,ω-alkanediols to alkadienes proceeds in a stepwise manner: C-α,ω-alkanediols react with aliphatic acids first to generate diesters; subsequent pyrolysis of the latter produces alkadienes. The highest yields of 1,5-hexadiene, 1,7-octadiene, and 1,9-decadiene were up to 70.3, 74.

CTGF Triggers Rat Astrocyte Activation and Astrocyte-Mediated Inflammatory Response in Culture Conditions.

To improve clinical outcomes for patients with traumatic brain injury (TBI), it is necessary to explore the mechanism of traumatic brain injury (TBI)-induced neuroinflammation. Connective tissue growth factors (CTGF) have been reported to be involved in the process of inflammatory response or tissue repair, whereas whether and how CTGF participates in the astrocyte-mediated inflammation after TBI remains unclear. In the present study, the TBI-induced activation of astrocytes and augmentation of inflammatory response were simulated by stimulating rat astrocytes with TGF-β1 or CTGF in cultured conditions.
