Research on Upper Limb Motion Intention Classification and Rehabilitation Robot Control Based on sEMG.

sEMG is a non-invasive biomedical engineering technique that can detect and record electrical signals generated by muscles, reflecting both motor intentions and the degree of muscle contraction. This study aims to classify and recognize nine types of upper limb motor intentions based on surface electromyography (sEMG) and apply them to the interactive control of an end-effector rehabilitation robot. The research begins with selecting muscles and data preprocessing, incorporating the generation mechanism of sEMG along with the anatomical and kinesiological principles of upper limb muscles.

The rise of antimicrobial resistance (AMR) in Gram-negative bacteria, including (), poses a major public health threat. This study aimed to address the limitations of existing antimicrobial peptides (AMPs) by designing hybrid peptides with enhanced targeting and antibacterial potency. Eight heptapeptide sequences were identified through phage display screening and hybridized with WP (WKKIWKPGIKKWIK), a peptide exhibiting weak antimicrobial activity against Gram-negative bacteria.

Microfluidic droplets with amended culture media cultivate a greater diversity of soil microorganisms.

Uncultivated but abundant soil microorganisms have untapped potential for producing broad ranges of natural products, as well as for bioremediation. However, cultivating soil microorganisms while maintaining a broad microorganism diversity to enable phenotyping and functional analysis of as diverse individual isolates as possible remains challenging. In this study, we developed and tested the ability of several culture media formulations that contain defined soil metabolites or soil extracts to maintain microorganism diversity during culture.

DDO1002, an NRF2-KEAP1 inhibitor, improves hematopoietic stem cell aging and stress response.

Oxidative stress diminishes the functionality of hematopoietic stem cells (HSCs) as age advances, with heightened reactive oxygen species (ROS) levels exacerbating DNA damage, cellular senescence, and hematopoietic impairment. DDO1002, a potent inhibitor of the NRF2-KEAP1 pathway, modulates the expression of antioxidant genes. Yet, the extent to which it mitigates hematopoietic decline post-total body irradiation (TBI) or in the context of aging remains to be elucidated.

Decanoylcarnitine improves liver mitochondrial dysfunction in hepatitis B virus infection by enhancing fatty acid β-oxidation.

Background: The incidence of metabolic-associated steatotic liver disease in patients with chronic hepatitis B is increasing annually; however, the interaction between hepatitis B virus (HBV) infection and lipid metabolism remains unclear. This study attempted to clarify whether fatty acid metabolism regulation could alleviate mitochondrial dysfunction caused by HBV infection.

Methods: Public gene set of human livers was analyzed, and a proteomic analysis on mouse livers was conducted to explore metabolic disorders and affected organelles associated with HBV infection.

Development of targeted antimicrobial peptides for Escherichia coli: Combining phage display and rational design for food safety application.

The growing demand for minimally processed foods has heightened the risk of pathogenic contamination. Balancing antimicrobial efficacy with the preservation of probiotic activity remains a significant challenge. In this study, we employed phage display peptide library screening, combined with next-generation sequencing to identify the HIMPIQA domain, which selectively targets pathogenic Escherichia coli (E.

Catalytic Methane Decomposition on In Situ Reduced FeCo Alloy Catalysts Derived from Layered Double Hydroxides.

Catalytic methane decomposition (CMD) reaction is considered a promising process for converting greenhouse gas CH into hydrogen and high-value-added carbon materials. In this work, a series of AlO-supported FeCo alloy catalysts were successfully prepared in the CMD process. Compared to the pre-reduced catalysts, the in situ reduced FeCo alloy catalysts showed higher methane conversion rates, with the highest reaching 83% at 700 °C, due to the finer active nanoparticle size and greater exposure of active site.

NOVAsort for error-free droplet microfluidics.

High-throughput screening techniques are pivotal to unlocking the mysteries of biology. Yet, the promise of droplet microfluidics in enabling single-cell resolution, ultra-high-throughput screening remains largely unfulfilled. Droplet sorting errors caused by polydisperse droplet sizes that are often inevitable in multi-step assays have severely limited the effectiveness and utility of this technique, especially when screening large libraries.

IL-33-Pretreated Mesenchymal Stem Cells Attenuate Acute Liver Failure by Improving Homing and Polarizing M2 Macrophages.

Mesenchymal stem cells (MSCs) are highly effective in the treatment of acute liver failure (ALF). The efficacy of MSCs is closely related to the inflammatory environment. Therefore, we investigated the functional changes of MSCs in response to interleukin-33 (IL-33) stimulation.

Overexpression of TPD52L2 in HNSCC: prognostic significance and correlation with immune infiltrates.

Background: Evidence has been presented that the tumor protein D52 (TPD52) family plays a critical role in tumor development and progression. As a member of the TPD52 family, the changes in TPD52L2 gene status are instrumental in kinds of cancer development. However, its effects on patient prognosis and immune infiltration in Head and Neck Squamous Carcinoma (HNSCC) are still poorly understood.

A novel nonsense mutation c.747C>G in the NEUROD1 gene detected within a Chinese family affected by maturity-onset diabetes of the young type 6.

Highlights Maturity-onset diabetes of the young type 6 (MODY6) is a rare form of monogenic diabetes mellitus due to NEUROD1 gene mutation on chromosome 2q32. A 21-year-old woman exhibiting weight loss, polyuria, and hyperglycemia was initially misdiagnosed with type 1 diabetes mellitus. Considering the early-onset age, a three-generation family history of diabetes, and negative autoimmune antibodies, a MODY diagnosis was suspected.

Importance: In several randomized clinical trials, endovascular thrombectomy led to better functional outcomes than conventional treatment at 90 days poststroke in patients with acute basilar artery occlusion. However, the long-term clinical outcomes of these patients have not been well delineated.

Objective: To evaluate 1-year clinical outcomes in patients with acute basilar artery occlusion following endovascular thrombectomy vs control.

High-Efficiency Interdigitated Electrode-Based Droplet Merger for Enabling Error-Free Droplet Microfluidic Systems.

Merging two droplets into a droplet to add and mix two contents is one of the common droplet microfluidic functions with droplet generation and sorting, performing broad ranges of biological and chemical assays in droplets. However, traditional droplet-merging techniques often encounter unsynchronized droplets, causing overmerging or mis-merging, and unwanted merging outside of the desired zone. This is more severe when the incoming droplets to be merged are polydisperse in their sizes, often observed in assays that require long-term incubation, elevated-temperature, and/or multiple droplet processing steps.
