SARS-CoV-2 infection of human pluripotent stem cell-derived vascular cells reveals smooth muscle cells as key mediators of vascular pathology during infection.

Although respiratory symptoms are the most prevalent disease manifestation of infection by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), nearly 20% of hospitalized patients are at risk for thromboembolic events. This prothrombotic state is considered a key factor in the increased risk of stroke, which is observed clinically during both acute infection and long after symptoms clear. Here, we develop a model of SARS-CoV-2 infection using human-induced pluripotent stem cell-derived endothelial cells (ECs), pericytes (PCs), and smooth muscle cells (SMCs) to recapitulate the vascular pathology associated with SARS-CoV-2 exposure.

Since the pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported from Wuhan, China, there has been a surge in scientific research to find a permanent cure for the disease. The main challenge in effective drug discovery is the continuously mutating nature of the SARS-CoV-2 virus. Thus, we have used the I-TASSER modeling to predict the structure of the SARS-CoV-2 viral envelope protein followed by combinatorial computational assessment to predict its putative potential small molecule inhibitors.

Acute leukoencephalopathy with restricted diffusion (ALERD) is an emerging clinico-radiological syndrome marked by sudden onset encephalopathy and characteristic restricted diffusion in the subcortical white matter on MRI. While typically linked to other viral etiologies, its association with dengue fever is not well known and is rarely documented in the literature. In this report, we describe a rare case of ALERD associated with dengue fever in a young patient, emphasizing clinical features, neuroimaging findings, management, and outcome.

Newcastle disease (ND) is among the most common and deadliest poultry diseases worldwide. Thermostable Newcastle disease virus (NDV) vaccines have been widely used to protect village chickens against ND due to their decreased dependence on cold chains for transport and storage. The NDV4 Heat-Resistant (NDV4HR) vaccine is an apathogenic, heat-resistant, live vaccine that can induce immunity in chickens.

Background: Respiratory infection is a major cause of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). We investigated the presence of bacterial and viral pathogens and clinical features in patients with AECOPD.
Methods: This retrospective study included 1,186 patients diagnosed with AECOPD from 28 hospitals in South Korea between 2015-2018.
