Background: Gastric cancer (GC) is one of the most common malignant tumors in the world. It has become increasingly difficult to meet the needs of precision therapy using the existing molecular typing system. Therefore, developing a more effective molecular typing system for GC is urgent.
Methods: In this study, 100 Chinese GC patients were included. Whole-exome sequencing (WES) and metabolomics analysis were performed to reveal the characteristics of genomic and metabolic changes.
Results: In WES, nonsynonymous mutations accounted for the majority. Based on metabolomics, GC has been divided into three subtypes with distinct metabolic features. Importantly, we ultimately divided GC into four subtypes with different metabolic characteristics, genomic alterations, and clinical prognoses by incorporating biomics analysis.
Conclusions: Integrating biological features, we constructed a novel molecular system for GC that was closely related to genetics and metabolism, providing new insights for further understanding the heterogeneity and formulating precise treatment strategies.

Introduction: HLA matching is critical for successful kidney transplantation. This study aimed to investigate the impact of eplet mismatches and Predicted Indirectly Recognizable HLA Epitopes (PIRCHE-II) scores on the development of de novo donor-specific antibodies (dnDSA) and graft survival in a Tunisian cohort, characterized by a high prevalence of living donors and significant genetic diversity in HLA profiles.
Methods: This retrospective study included 112 adult kidney transplant recipients who underwent transplantation between 2012 and 2018.

Background: Avian mycoplasmas are small bacteria associated with several pathogenic conditions in many wild and poultry bird species. Extensive genomic data are available for many avian mycoplasmas, yet no comparative studies focusing on this group of mycoplasmas have been undertaken so far.
Results: Here, based on the comparison of forty avian mycoplasma genomes belonging to ten different species, we provide insightful information on the phylogeny, pan/core genome, energetic metabolism, and virulence of these avian pathogens.

Yeast strains representing a novel asexual ascomycetous species were isolated from seven flowers. Sequencing of the chromosomal regions coding for the D1/D2 domains of the large subunit ribosomal RNA, the ITS1-5.8S-ITS2 segments and parts of the gene coding for the small subunit ribosomal RNA showed that the isolates were conspecific.

Whole genome sequencing (WGS) is pivotal for the molecular characterization of ()-the leading bacterial cause of sexually transmitted infections and infectious blindness worldwide. WGS can inform epidemiologic, public health and outbreak investigations of these human-restricted pathogens. However, challenges persist in generating high-quality genomes for downstream analyses given its obligate intracellular nature and difficulty with propagation.
