The study deals with the current topical problem in the development of a laboratory algorithm for the detection of early stages of HIV infection and for the creation of a monitoring system on this basis for the spread of drug-resistant HIV-1 strains. The paper presents the results of experimental examination of the most accessible health care methods for the differential diagnosis of early HIV infection, by using the test systems in Russia and gives practical recommendations on their application.

Single-cell RNA sequencing (scRNA-seq) offers remarkable insights into cellular development and differentiation by capturing the gene expression profiles of individual cells. The role of dimensionality reduction and visualization in the interpretation of scRNA-seq data has gained widely acceptance. However, current methods face several challenges, including incomplete structure-preserving strategies and high distortion in embeddings, which fail to effectively model complex cell trajectories with multiple branches.

Background: Varicocele (Vx) which is the most treatable cause of male infertility, is also associated with low sperm count, decreased sperm motility and increased sperm abnormal morphology. We aimed in the current study to evaluate the correlation between seminal α-Glycerylphosphorylcholine (αGPC) and semen parameters in infertile patients pre- and post- sub-inguinal micro-varicocelectomy.
Methods: The current comparative prospective study was carried out on 20 male patients who presented to Kasr Al-Ainy Hospitals from March 2022 to March 2023 as well as 20 healthy controls.

Background: The DCDDaily-questionnaire (DCDDaliy-Q) evaluates children's performance and participation in motor-based activities of daily living (ADLs), meeting diagnostic criterion B for developmental coordination disorder (DCD). Currently, there are no Chinese translations or growth references available. Thus, this study aimed to culturally adapt, validate, and establish reference norms for the DCDDaily-Q in Chinese children.

Introduction: Oncolytic herpes simplex viruses (oHSVs) are a type of biotherapeutic utilized in cancer therapy due to their ability to selectively infect and destroy tumor cells without harming healthy cells. We sought to investigate the functional genomic response and altered metabolic pathways of human cancer cells to oHSV-1 infection and to elucidate the influence of these responses on the relationship between the virus and the cancer cells.
Methods: Two datasets containing gene expression profiles of tumor cells infected with oHSV-1 (G207) and non-infected cells from the Gene Expression Omnibus (GEO) database were processed and normalized using the R software.

Background: Breast cancer remains a leading cause of mortality among women, driven by the molecular complexity of its various subtypes. This study aimed to investigate the differential expression of genes and miRNAs involved in the PI3K/AKT/mTOR signaling pathway, a critical regulator of cancer progression.
Methods: We analyzed tumor tissues from five breast cancer subtypes-luminal A, luminal B HER2-negative, luminal B HER2-positive, HER2-positive, and triple-negative breast cancer (TNBC)-and compared them with non-cancerous tissues.
