Co-Infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2) and Human Coronavirus HKU1 (HCoV-HKU1).

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and human coronavirus HKU1 (HCoV-HKU1) are two forms of human coronaviruses known to cause respiratory tract symptoms. A co-infection with both viruses is rare, particularly in the United States.

Case Description: An 85-year-old male presented to the Emergency Department with recurrent falls, diarrhoea and cough, and whose viral panel was positive for both SARS-COV-2 and HCoV-HKU1.

Membrane trafficking and exocytosis are upregulated in port wine stain blood vessels.

Introduction: Port wine stain (PWS) is characterized as a progressive dilatation of immature venule-like vasculatures which result from differentiation-impaired endothelial cells. In this study, we aimed to identify the major biological pathways accounting for the pathogenesis of PWS.

Methods: Sequential windowed acquisition of all theoretical fragment ion mass spectra (SWATH-MS) was used to identify differentially expressed proteins in PWS lesions, followed by confirmative studies with immunohistochemistry, immunoblot and transmission electron microscopy (TEM).
