Isolation and molecular characterization of an enteric isolate of the genotype-Ia bovine coronavirus with notable mutations in the receptor binding domain of the spike glycoprotein.

BCoV new isolate was plaque purified, isolated, and propagated in vitro using MDBK and HRT-18. The full-length genome sequencing of this new BCoV isolate (31 Kbs) was drafted and deported in the GenBank. The genome organization is (5'-UTR-Gene-1-32kDa-HE-S-4.

The clinical and functional outcomes of closed reduction and arthroscopic McLaughlin procedure in patients with neglected locked posterior shoulder dislocation.

Introduction: Posterior shoulder dislocation with a reverse Hill-Sachs lesion is a rare and complex injury, requiring specialized treatment due to the difficulty in diagnosis, reduction, and addressing both sides of the pathology to reduce the potential for recurrent dislocation.

Purpose: To evaluate the clinical and functional outcomes of closed reduction and arthroscopic McLaughlin procedure with posterior labral repair in patients with neglected locked posterior shoulder dislocation for less than 12 weeks.

Methods: A prospective study was conducted at university hospitals, managing 15 patients with neglected locked posterior shoulder dislocation for less than 12 weeks and concomitant engaging reverse Hill-Sachs lesions of less than 40% of the humeral articular surface.

The dual actions of miRNA16a in restricting Bovine Coronavirus replication through downregulation of Furin and enhancing the host immune response.

The roles of host cell miRNAs have not been well studied in the context of BCoV replication and immune regulation. This study aimed to identify miRNA candidates that regulate essential host genes involved in BCoV replication, tissue tropism, and immune regulation. To achieve these goals, we used two isolates of BCoV (enteric and respiratory) to infect bovine endothelial cells (BECs) and Madine Darby Bovine Kidney (MDBK) cells.

The ex vivo infection model of the peripheral bovine mononuclear cells (PBMCs) and the bovine spleen cells with the bovine coronavirus (BCoV) induced a differential expression of the host cytokine genes profiles and modulates the virus replication.

The adaptive immune response during BCoV infection of peripheral blood mononuclear cells (PBMCs), the bovine spleen cells, and their isolated T lymphocytes was not studied well. Our study confirmed successful BCoV infection in PBMCs and spleen T cells. The BCoV replication was evidenced by measuring genome copy numbers using real-time PCR and expression levels of BCoV spike and nucleocapsid proteins via western blot and immunofluorescence assays.

Digitally Enabled Generic Analytical Framework Accelerating the Pace of Liquid Chromatography Method Development for Vaccine Adjuvant Formulations.

The growing use of adjuvants in the fast-paced formulation of new vaccines has created an unprecedented need for meaningful analytical assays that deliver reliable quantitative data from complex adjuvant and adjuvant-antigen mixtures. Due to their complex chemical and physical properties, method development for the separation of vaccine adjuvants is considered a highly challenging and laborious task. Reversed-phase liquid chromatography (RPLC) is among the most important tests in the (bio)pharmaceutical industry for release and stability indicating measurements including adjuvant content, identity, and purity profile.
