Bacterial vaginosis is associated with transcriptomic changes but not higher concentrations of cervical leukocytes in a study of women at high risk for HIV acquisition.

Background: The association between bacterial vaginosis (BV) and increased HIV acquisition risk may be related to concentrations of HIV-susceptible immune cells in the cervix.

Methods: Participants (31 with BV and 30 with normal microbiota) underwent cervical biopsy at a single visit. Immune cells were quantified and sorted using flow cytometry (N=55), localization assessed by immunofluorescence (N=16), and function determined by bulk RNA sequencing (RNA-seq) of live CD45+ cells (N=21).

Mitochondrial microRNAs: Key Drivers in Unraveling Neurodegenerative Diseases.

MicroRNAs (miRNAs) are a class of small non-coding RNAs (ncRNAs) crucial for regulating gene expression at the post-transcriptional level. Recent evidence has shown that miRNAs are also found in mitochondria, organelles that produce energy in the cell. These mitochondrial miRNAs, also known as mitomiRs, are essential for regulating mitochondrial function and metabolism.

AntiCD30-Conjugated Antibody Plus Standard BEAM as Conditioning Regimen for Autologous Hematopoietic Stem Cell Transplantation in Systemic Anaplastic Large Cell Lymphoma.

The outcome of refractory/relapsed systemic Anaplastic Large Cell Lymphoma (R/R-sALCL), especially for anaplastic lymphoma kinase-1 (ALK-1)-negative disease, remains dismal even after autologous hematopoietic stem cell transplantation (AHSCT). The intensification of both salvage and conditioning regimens, without increasing the toxicity, could improve the outcome of AHSCT in R/R-sALCL. Based on the successful experience of the incorporation of antiD20 monoclonal antibodies in the treatment of B-Cell Lymphomas, we designed a salvage and conditioning regimen incorporating the antiCD30-conjugated antibody (Brentuximab Vedotin, BV) to standard chemotherapy regimens, and we describe herein the clinical course of a patient with AKL-ve, R/R-sALCL, who received salvage regimen BV + DHAP, followed by AHSCT with preparative regimen consisted of BV plus standard BEAM.

Food Safety Concerns in Pakistan: Monitoring of Antimicrobial-Resistant Bacteria and Residue Contamination in Commercially Available Fish and Poultry Meat Samples.

Food safety is a critical issue in the 21st century due to antibiotic-resistant bacteria causing harmful foodborne diseases. This comprehensive study meticulously examined the presence of bacterial isolates, quinolone residue, and antimicrobial resistance genes in samples of broiler and fish meat. Forty samples were collected from various locations in the Faisalabad metropolis.
