Isolation, characterization and virulence assessment of Type 1d CP bovine viral diarrhea virus originating from Inner Mongolia, China.

In recent years, bovine viral diarrhea virus (BVDV) has been associated with increased respiratory and gastrointestinal diseases in cattle. Comprehensive monitoring and investigations into the virus's pathological features are crucial for developing effective prevention strategies. This study investigated BVDV prevalence and pathogenicity in farms undergoing elimination protocols, with a focus on characterizing a novel Cytopathic Bovine Viral Diarrhea Virus (CP-type BVDV) strain (HH839) isolated from a symptomatic calf in Hohhot, Inner Mongolia.

A giant and rapid myocardial remodeling due to fatal giant cell myocarditis: a case report.

Giant cell myocarditis is a rare and rapidly progressive disease with a high mortality rate. We present the case of a 21-year-old male without a medical history who presented with a giant left ventricle (9.9 cm, EF:10%) and in a severe clinical state.

Inhibition of LncRNA Attenuates Testicular Torsion-Induced Apoptosis and Preserves Blood-Testis Barrier Integrity.

Testicular torsion is a common emergency in adolescents, and can lead to severe ischemia reperfusion injury (IRI). LncRNA has been shown to increase during ischemia, but its role in testicular IRI remains unknown. Focusing on this research gap, we utilized biallelic mutant mice and Sertoli cell line (TM4) to construct in vivo and in vitro models of ischemia/reperfusion (I/R) and oxygen-glucose deprivation/reperfusion (OGD/R).

A structure-based framework for selective inhibitor design and optimization.

Structure-based drug design aims to create active compounds with favorable properties by analyzing target structures. Recently, deep generative models have facilitated structure-specific molecular generation. However, many methods are limited by inadequate pharmaceutical data, resulting in suboptimal molecular properties and unstable conformations.

Exploration of a modified pretreatment process coupled with GC-MS/MS for determination of 18 phthalates in edible oils.

Phthalates (PAEs), which are pollutants that most easily migrate from plastic packages to edible oils, have received increasing attention. In this work, a sample preconditioning method was proposed and explored, involving a single-step extraction using a methanol and ethyl hexanoate mixed solvent, followed by clean-up with a mixed absorbent of graphitic carbon nitride (g-CN) and -propyl ethylenediamine (PSA), for the determination of 18 PAEs in oil samples through GC-MS/MS analysis. The triazine ring structure and conjugated aromatic heterocyclic accumulation structure of g-CN and the amino-rich structure of PSA can provide hydrogen bonds, conjugated π-π interactions, and hydrophobic effects for the removal of interferences such as organic acids, aliphatic acids, and pigments.
