Development and Evaluation of In-House ELISAs for the Detection of SARS-CoV-2-Specific Antibodies in COVID-19 Patients in Sri Lanka.

COVID-19 serological tests complement the molecular diagnostics and can be used as important tool for serosurveillance and vaccine efficiency evaluation. The aim of this study was to develop and evaluate the diagnostic performance of an in-house ELISA for retrospective serosurveillance of SARS-CoV-2. Total IgG and IgM levels in sera of PCR positive SARS-CoV-2 patients ( = 50) from North Colombo Teaching Hospital were evaluated and compared with sera ( = 50) collected from prepandemic healthy individuals as controls.

Living Conditions and Malaria: A Longitudinal Study in a Rural Malaria-Endemic Area of Sri Lanka.

This study was conducted in a rural malaria-endemic community in Sri Lanka in 2014-2015 because malaria was no longer endemic in the area as of November 2012. Data on sociodemographic factors, living conditions, malaria infections, and use of mosquito protection methods during the period from 1990 to 2015 were collected through a household survey in a systematically selected sample of 724 households, covering >10% of the population in the area. Malaria incidence data were obtained from Anti-Malaria Campaign, and Malaria Research Unit of the University of Colombo.

Effects of post-fermentation addition of green tea extract for sulfur dioxide replacement on Sauvignon Blanc wine phenolic composition, antioxidant capacity, colour, and mouthfeel attributes.

This study examines the feasibility of replacing SO in a New Zealand Sauvignon Blanc wine with a green tea extract. The treatments included the control with no preservatives (C), the addition of green tea extract at 0.1 and 0.

Clinical Exome Gene Panel Analysis of a Cohort of Urothelial Bladder Cancer Patients from Sri Lanka.

Background: Bladder cancer has a high rate of recurrence and high mortality rates in those who progress to muscle invasive disease. Biomarkers and molecular sub classification of tumours beyond standard histopathology has been proposed to address therapeutic dilemmas. The Cancer Genome Atlas project and other studies have contributed to the enhanced knowledge base of the mutational landscape of urothelial bladder cancer.
