AbstractMetabarcoding of microbial eukaryotes (collectively known as protists) has developed tremendously in the last decade, almost uniquely relying on the 18S rRNA gene. As microbial eukaryotes are extremely diverse, many primers and primer pairs have been developed. To cover a relevant and representative fraction of the protist community in a given study system, a wise primer choice is needed as no primer pair can target all protists equally well. As such, a smart primer choice is very difficult even for experts and there are very few on-line resources available to list existing primers. We built a database listing 179 primers and 76 primer pairs that have been used for eukaryotic 18S rRNA metabarcoding. In silico performance of primer pairs was tested against two sequence databases: PR2 for eukaryotes and a subset of Silva for prokaryotes. This allowed to determine the taxonomic specificity of primer pairs, the location of mismatches as well as amplicon size. We developed a R-based web application that allows to browse the database, visualize the taxonomic distribution of the amplified sequences with the number of mismatches, and to test any user-defined primer set (https://app.pr2-primers.org). This tool will provide the basis for guided primer choices that will help a wide range of ecologists to implement protists as part of their investigations.

Abstract: Blood donation is a vital component of international healthcare and has suffered because of the pandemic. This paper aims to address this issue by proposing the creation of a totally transparent blood bank management system in which hospitals/NGOs input the quantity of each blood type in their stock, after which nearby users who are ready to donate are notified. Following extensive research, we observed that there is no structure in place that provides a communication link between the management of blood banks (Hospitals and NGOs) and the general public, allowing available donors to view which blood banks have a shortage of their blood group. The technology platform in implementing this system uses Python programming environment Django for SQL and deployment. For frontend development, HTML5, CSS3, JavaScript, and Bootstrap were utilized. The system alleviates the issues created by blood shortages in blood banks by properly managing and providing a single platform for everyone. It makes information about available stock in each blood bank available to the public and this can be extended to multiple cities. Keywords: Blood donation, Blood stock, Hospital, Donor, System
