Artificial Intelligence in Healthcare Competition (TEKNOFEST-2021): Stroke Data Set.

Objective: The artificial intelligence competition in healthcare was organized for the first time at the annual aviation, space, and technology festival (TEKNOFEST), Istanbul/Türkiye, in September 2021. In this article, the data set preparation and competition processes were explained in detail; the anonymized and annotated data set is also provided via official website for further research.

Materials And Methods: Data set recorded over the period covering 2019 and 2020 were centrally screened from the e-Pulse and Teleradiology System of the Republic of Türkiye, Ministry of Health using various codes and filtering criteria.

Seroprevalence of coronavirus disease 2019 (COVID-19) among health care workers from three pandemic hospitals of Turkey.

COVID-19 is a global threat with an increasing number of infections. Research on IgG seroprevalence among health care workers (HCWs) is needed to re-evaluate health policies. This study was performed in three pandemic hospitals in Istanbul and Kocaeli.

Determination of the type and quantity of sialic acid in the egg jelly coat of the sea urchin Paracentrotus lividus using capillary LC-ESI-MS/MS.

Sialic acid is a terminal sugar of carbohydrate chains that participates in numerous biological events. Recent studies have explored the mechanism of carbohydrate-mediated fertilisation to understand the biochemistry of fertilisation, although the type and quantity of sialic acid and the role of sialic acid during fertilisation remain unknown. Echinoderm fertilisation in particular has been studied extensively, yet our understanding of the mechanisms of carbohydrate-mediated fertilisation and the role of sialic acid remains incomplete.
