Motivation: graphics for RNA-sequencing and microarray gene expression analyses may contain upwards of tens of thousands of points. Details about certain genes or samples of interest are easily obscured in such dense summary displays. Incorporating interactivity into summary plots would enable additional information to be displayed on demand and facilitate intuitive data exploration.
Results: The open-source Glimma package creates interactive graphics for exploring gene expression analysis with a few simple R commands. It extends popular plots found in the limma package, such as multi-dimensional scaling plots and mean-difference plots, to allow individual data points to be queried and additional annotation information to be displayed upon hovering or selecting particular points. It also offers links between plots so that more information can be revealed on demand. Glimma is widely applicable, supporting data analyses from a number of well-established Bioconductor workflows ( limma , edgeR and DESeq2 ) and uses D3/JavaScript to produce HTML pages with interactive displays that enable more effective data exploration by end-users. Results from Glimma can be easily shared between bioinformaticians and biologists, enhancing reporting capabilities while maintaining reproducibility.
Availability And Implementation: The Glimma R package is available from http://bioconductor.org/packages/Glimma/ .

To analyze a novel intronic variant in the SPTB gene and explore its effect on SPTB mRNA splicing. Clinical data of a child diagnosed with hereditary spherocytosis (HS) and admitted to the First Affiliated Hospital of Xi'an Jiaotong University in February 2022 were analyzed retrospectively. Whole genome sequencing was used to identify disease-causing mutations and the results were validated with Sanger sequencing, mRNA sequencing was used to determine the SPTB gene's mRNA expression level, and bioinformatics tools were used for splicing site prediction and analysis.

Fabrication of macroporous scaffolds with favorable mechanical and biological properties based on natural polysaccharides embedding inorganic components has emerged as a promising alternative for bone regeneration. We hypothesized that partially demineralized chitin containing natural calcium phosphate with suitable mechanical strength as the inorganic component is more favorable for this purpose than commonly used nano-hydroxyapatite (nHA). Therefore, a macroporous cryogel scaffold composed of gelatin (G), nanofibrillated cellulose (NFC), and partially demineralized chitin (PDCh), chemically crosslinked with oxidized dextran (ODex), was developed in this study.

Appetite regulation is a lifestyle intervention strategy to maintain health. The regulatory effects of dietary fiber (especially insoluble dietary fiber), as a crucial element of the nutritional composition, on appetite remain poorly understood. This study investigated modulatory effects of konjac fiber (KF, with high and low expansion) and konjac powder (KP) on chyme digestion, gastrointestinal hormones, intestinal microbiota, appetite genes in hypothalamus, GLP-1 receptor (GLP-1R) protein in various tissues of rats by dietary intervention.
