Serum α-L-Fucosidase Activity Measured for COVID-19 Infection
An unusual fucosylated LacdiNAc in the receptor-binding domains of the spike protein of COVID-19 has been observed. Reduced fucosylation was also found in a specific Fc domain of IgG antibodies in COVID-19 patients that enhanced the interactions with the activating FcγR, FcγRIIIa. More...22 Apr 2021

Spatial Landscape of Lung Pathology Investigated During COVID-19 Progression
Early histopathological changes of viral pneumonias are rarely observed because histopathological examination is not necessary for diagnosis, but late stage changes in viral pneumonias are well defined, most commonly in autopsy series. More...13 Apr 2021
Serious Infections Prevalent in ANCA-Associated Vasculitis
Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are among the rheumatic diseases with the highest mortality and morbidity, due to their major multi-organ involvement (lungs, kidneys) and their relapsing nature requiring aggressive immunosuppressive treatment. More...08 Apr 2021
Toxoplasmosis Immune Status in Pregnancy Determined by Immunochromatography Assay
Toxoplasmosis is a disease that results from infection with the Toxoplasma gondii parasite, one of the world's most common parasites. Infection usually occurs by eating undercooked contaminated meat, exposure from infected cat feces, or mother-to-child transmission during pregnancy. More...30 Mar 2021
Vitamin D Levels Tied to COVID-19 Risk for African-Americans
Vitamin D has diverse physiological effects, including on calcium regulation, bone density, and immune function. Deficient levels, typically defined as 25-hydroxyvitamin D (also known as calcifediol) level less than 20 ng/mL are common, especially in African-Americans individuals. More...29 Mar 2021
White Blood Cell Help Define Pediatric Urinary Tract Infections
Urinary tract infections account for up to 7% of fevers in children up to 24 months old and are a common driver of hospital emergency room visits. These bacterial infections in infants and toddlers can be difficult to diagnose because their symptoms are similar to other fever-causing conditions. More...25 Mar 2021
