Abstract

Generating grasps for a dexterous hand often requires numerous grasping annotations. However, annotating high DoF dexterous hand poses is quite challenging. Especially for functional grasps, requiring the hand to grasp the object in a specific pose to facilitate subsequent manipulations. This prompts us to explore how people achieve manipulations on new objects based on past grasp experiences. We find that when grasping new items, people are adept at discovering and leveraging various similarities between objects, including shape, layout, and grasp type. Considering this, we analyze and collect grasp-related similarity relationships among 51 common tool-like object categories and annotate semantic grasp representation for 1768 objects. These objects are connected through similarities to form a knowledge graph, which helps infer our proposed cross-category functional grasp synthesis. Through extensive experiments, we demonstrate that the grasp-related knowledge indeed contributed to achieving functional grasp transfer across unknown or entirely new categories of objects.

Abstract

Ulcerative colitis is a chronic inflammatory bowel disease, and its incidence is increasing year by year in China. Current drug treatments have side effects, so the use of probiotics to regulate intestinal microbiota is emerging as an intervention method. Numerous studies have shown that bifidobacteria have a good clinical effect in alleviating symptoms of ulcerative colitis. However, the underlying mechanism has not been systematically elucidated. In recent years, with continuous breakthroughs in research on multi-omics, the gut microbiota, the gut-brain axis, and the gut-liver axis, significant progress has been made in understanding the action mechanism of bifidobacteria in alleviating ulcerative colitis. This article reviews the latest progress that has been made in the research and application of bifidobacteria in alleviating ulcerative colitis in the past decade, and introduces bifidobacteria alleviating ulcerative colitis, with a focus on the underlying mechanism. This review reports that bifidobacteria alleviates ulcerative colitis mainly by regulating the structure of the intestinal microbiota, restoring intestinal barrier function, improving intestinal immune response, regulating intestinal purine metabolism, inhibiting oxidative stress, and providing energy for the intestinal epithelium. It is our hope that this review will provide a reference for further elucidating the regulatory mechanism of bifidobacteria on life and health as well as for furthering the application and promotion of probiotic preparation.

Abstract

As an extension of the previous research, this study aimed to comprehensively characterize the genome of Bacillus subtilis SNBS-3. Illumina second-generation sequencing technology and the third-generation high-throughput Pacbio sequencing platform were used for whole-genome sequencing of B. subtilis SNBS-3 isolated from traditional bean paste to obtain the key information of genome characteristics, gene function annotation and classification, phylogenetic evolution, and secondary metabolites. The results showed that the genome of SNBS-3 was a closed circular DNA of 4 076 387 bp in length containing 4 000 protein-coding genes. A total of 3 209, 2 824, 2 560, 147, 12 and 4 functional genes were annotated in the Clusters of Orthologous Groups (COG), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), Carbohydrate-Active Enzymes (CAZyme), Comprehensive Antibiotic Resistance Database (CARD) and Virulence Factor Database (VFDB), respectively. Using the online software AntiSMASH and Bagel4, we found that it contained genes related to the synthesis of surfactin, mycosubtilin, plipastatin, bacilysin and bacillaene, as well as a complete gene cluster for the synthesis of the bacteriocin subtilosin A. Based on the results of antimicrobial test and proteinase K test, it was hypothesized that B. subtilis SNBS-3 had the ability to synthesize subtilosin A. In conclusion, the whole genome sequencing results of B. subtilis SNBS-3 show that it can produce a variety of bacteriostatic substances and thus have biocontrol potential. The results from this study provide a theoretical basis for further development and application of various bacteriostatic substances including the bacteriocin subtilosin A.
