Antigenic relationships among neuraminidases of influenza B viruses isolated in 1940-1980 were studied by means of the neuraminidase activity inhibition test using hypoimmune sera from rats and roosters. Cross-reactions between influenza B virus enzymes showed their antigenic heterogeneity. The results permit conclusion that among influenza B virus strains both the drift and shift variants may be distinguished by the antigenic composition of the neuraminidase component.

Infection with Influenza A virus (IAV) induces severe inflammatory responses and lung injury, contributing significantly to mortality and morbidity rates. Alterations in the microbial composition of the lungs and intestinal tract resulting from infection could influence disease progression and treatment outcomes. Xiyanping (XYP) injection has demonstrated efficacy in clinical treatment across various viral infections.

Background: Alveolar epithelial cells (AECs) are the primary targets of many pathogens and play an important role in sensing viruses and regulating immunity. Yet, little is known about the antiviral responses in the aged AECs.
Methods: The responses of young or aged AECs after viral infection were analyzed using methods such as flow cytometry, quantitative real-time PCR, Western blot detection, and transwell chemotaxis assay.
Introduction: Interventions aimed at preventing and treating maternal infections during the gestational period are of paramount importance. Timely immunizations, screening strategies and management of maternal infections reduce the risk of complications for the developing fetus and play a pivotal role in improving neonatal outcomes.
Summary: We summarize evidence for a total of thirteen interventions, pertaining to the prevention and treatment of maternal infections during the antenatal period, from Every Newborn Series published in The Lancet 2014.

Pathogen nucleic acid detection technology based on isothermal amplification and CRISPR/Cas12a system offers advantages in terms of high sensitivity, high specificity, and rapidity. However, this method has not been widely applied because of its shortcomings in utilizing conventional instruments, which cannot satisfy the requirements for Point of Care Testing (POCT), such as integration, convenience, and miniaturization. In this study, we developed an integrated lift-heater centrifugal microfluidic platform (Lift-CM) to automate the processes of isothermal amplification and CRISPR/Cas12a detection.
