[Safety and efficacy of Relatox in comparison with Dysport in the treatment of focal spasticity of the upper limb in patients after stroke and traumatic brain injury (results of a prospective simple blind randomized comparative study in parallel groups)].

Objective: Evaluation of the safety and effectiveness of Relatox, botulinum toxin type A in patients with focal spasticity (FS) of the upper limb as a result of a cerebrovascular accident (CVA) or traumatic brain injury (TBI).

Material And Methods: A multicenter, prospective, single-blinded, randomized, comparative clinical study included 210 patients of both sexes aged 18-75 years after moderate to severe TBI and CVA in seven sites in the Russian Federation. The patients were randomized into two groups.

Large Language Model for Automating the Analysis of Cryoprotectants.

The rapid expansion of scientific literature necessitates developing efficient data extraction and analysis methods. This study presents an innovative approach to automating the extraction of cryoprotectant information from scientific publications using a generative pretrained transformer (GPT) model integrated with a Telegram bot interface. Our system processes and analyzes scientific articles to identify and extract relevant data on cryoprotectants and bacteria, significantly reducing the time required for researchers to gather essential information.

Cognitive dysfunction and disturbed daily activities of people with dementia impact the psychological stress in family caregivers depending on their anxiety and depression severity.

Care for individuals with dementia, predominantly provided by family members, was associated with significant physical and emotional stress. Existing guidelines for supporting caregivers were frequently based on limited evidence. A cross-sectional clinical study involving 104 pairs of caregivers and individuals with dementia was conducted.

Creation of Cellulolytic Communities of Soil Microorganisms-A Search for Optimal Approaches.

For the targeted selection of microbial communities that provide cellulose degradation, soil samples containing cellulolytic microorganisms and specific plant residues as a substrate can be used. The details of this process have not been studied: in particular, whether the use of different soils determines the varying efficiency of communities; whether these established cellulolytic communities will have substrate specificity, and other factors. To answer these questions, four soil microbial communities with different cellulolytic activity (Podzol and the soil of Chernevaya taiga) and substrates (oat straw and hemp shives) with different levels of cellulose availability were used, followed by trained communities that were tested on botrooth substrates (in all possible combinations).

Changes in the Tissue Barrier after Exposure to Lipopolysaccharide on the Apical Side of Enterocytes and the Follicle-Associated Epithelium in Peyer's Patches of the Rat Intestine.

To study the para- and transcellular permeability of columnar epithelium and follicle-associated epithelium of Peyer's patches in the rat intestine, LPS was applied from the mucosal side to simulate the action of endotoxins from gram-negative bacteria of gut microbiota. LPS did not affect transepithelial resistance or sodium fluorescein permeability, but increased the levels of claudin-3 and claudin-4 in enterocytes, suggesting strengthening of the paracellular intestinal barrier. Transcellular permeability was evaluated by electron microscopy based on the number of vesicular structures in the cytoplasm of different cell types.
