HCV and HBV genotypes: vital in the progression of HCV/ HBV co-infection.

Background: Viral hepatitis is the major contributor to liver cirrhosis and hepatocellular carcinoma (HCC). Studies indicated that the co-infection of hepatitis C and hepatitis B virus also prompts liver damage progression. Therefore, in the present study, the prevalence of HCV-HBV co-infection and the impact of HCV-HBV co-infection on the progression of liver damage was evaluated amongst the HCV-infected patients in Pakistan.

Spatiotemporal variation in population size and relative abundance of Kalij pheasant (Lophura leucomelanos) in scrub forest.

Most species of pheasants (Galliformes: Phasianidae) occur in Asia. In Pakistan, pheasants occur from 245-3050 m in altitude, and one of these, the Kalij pheasant (Lophura leucomelanos) is a large-bodied, brightly-colored habitat quality indicator species. The present study was designed to determine spatiotemporal variation, population size, and the relative abundance of Kalij pheasants in Haripur, Pakistan.

Gender disparities in adult patients undergoing emergency appendicectomy: A comparative analysis.

Background: Emergency appendicectomy (EA) is a common procedure, yet few studies have focused on gender differences in these patients. This study aims to evaluate the demographics, preoperative investigations, intraoperative findings, and clinical outcomes between males and females undergoing EA.

Methods: A multicenter retrospective observational study was conducted across four hospitals involving patients who underwent EA between August 2018 and November 2025.

A Global Collaborative Comparison of SARS-CoV-2 Antigenicity Across 15 Laboratories.

Setting up a global SARS-CoV-2 surveillance system requires an understanding of how virus isolation and propagation practices, use of animal or human sera, and different neutralisation assay platforms influence assessment of SARS-CoV-2 antigenicity. In this study, with the contribution of 15 independent laboratories across all WHO regions, we carried out a controlled analysis of neutralisation assay platforms using the first WHO International Standard for antibodies to SARS-CoV-2 variants of concern (source: NIBSC). Live virus isolates (source: WHO BioHub or individual labs) or spike plasmids (individual labs) for pseudovirus production were used to perform neutralisation assays using the same serum panels.

Comparison of imaging-based single-cell resolution spatial transcriptomics profiling platforms using formalin-fixed, paraffin-embedded tumor samples.

Imaging-based spatial transcriptomics (ST) is evolving rapidly as a pivotal technology in studying the biology of tumors and their associated microenvironments. However, the strengths of the commercially available ST platforms in studying spatial biology have not been systematically evaluated using rigorously controlled experiments. In this study, we used serial 5-m sections of formalin-fixed, paraffin-embedded surgically resected lung adenocarcinoma and pleural mesothelioma tumor samples in tissue microarrays to compare the performance of the single cell ST platforms CosMx, MERFISH, and Xenium (uni/multi-modal) platforms in reference to bulk RNA sequencing, multiplex immunofluorescence, GeoMx Digital Spatial Profiler, and hematoxylin and eosin staining data for the same samples.
