Review on Portable-Powered Lower Limb Exoskeletons.

Advancements in science and technology have driven the growing use of robots in daily life, with Portable-Powered Lower Limb Exoskeletons (PPLLEs) emerging as a key innovation. The selection of mechanisms, control strategies, and sensors directly influences the overall performance of the exoskeletons, making it a crucial consideration for research and development. This review examines the current state of PPLLE research, focusing on the aspects of mechanisms, control strategies, and sensors.

Regulation of Isoleucine on Colonic Barrier Function in Rotavirus-Infected Weanling Piglets and Analysis of Gut Microbiota and Metabolomics.

Rotavirus (RV) is a significant contributor to diarrhea in both young children and animals, especially in piglets, resulting in considerable economic impacts on the global pig industry. Isoleucine (Ile), a branched-chain amino acid, is crucial for regulating nutrient metabolism and has been found to help mitigate diarrhea. This study aimed to assess the impact of isoleucine supplementation in feed on colonic barrier function, colonic microbiota, and metabolism in RV-infected weanling piglets.

Bis-Iridoid Glycosides and Triterpenoids from and Their Potential as Inhibitors of ACC1 and ACL.

A comprehensive phytochemical investigation of the twigs/leaves and flower buds of , a rare deciduous shrub native to China, led to the isolation of 39 structurally diverse compounds. These compounds include 11 iridoid glycosides (- and -), 20 triterpenoids (, , and -), and 8 phenylpropanoids (-). Among these, amabiliosides A () and B () represent previously undescribed bis-iridoid glycosides, while amabiliosides C () and D () feature a unique bis-iridoid-monoterpenoid indole alkaloid scaffold with a tetrahydro--carboline-5-carboxylic acid moiety.

Photocatalytic Depolymerization of Lignin: C-O Bond Cleavage in β-O-4 Models Using S-Doped Ultra-Thin BiOCl Nanosheets.

The selective depolymerization of β-O-4 lignin models into high-value aromatic monomers using photocatalysis presents both significant opportunities and challenges. Photocatalysts often face issues such as high photogenerated carrier recombination rates and limited operational lifetimes. This study introduces S doping to modulate the surface interface of BiOCl (BOC) nanosheets, enhancing C-O bond cleavage efficiency in β-O-4 lignin models under visible light at ambient temperatures.

Na-K-ATPase/GLT-1 interaction participates in EGCG protection against cerebral ischemia-reperfusion injury in rats.

Background: In China, stroke is the primary cause of adult death and disability. Because of the increased rate of blood vessel reperfusion, it is important to prevent cerebral ischemia-reperfusion injury, in which glutamate (Glu) excitotoxicity plays a critical role. The most important Glu transporter, GLT-1, is essential for the regulation of Glu, which is dependent on Na-K-ATPase (NKA)-induced ion concentration gradient differences.
