Paramecia are unicellular eukaryotes of large size (~ 120 micrometers for P aurelia species) that belong to the ciliate phylum. Ciliates, like the Last Eukaryotic Common Ancestor, have the axonemal structure in the form of vibrating cilia that assure locomotion and food capture and are essential for pairing of paramecia of opposite mating types during conjugation (sexual reproduction). Like multicellular eukaryotes, ciliates separate germinal and somatic functions, harbouring two different kinds of nuclei. A diploid germinal micronucleus transmits the genetic information to the next sexual generation, while a polyploid somatic macronucleus is responsible for gene expression. Reproducible DNA elimination, which occurs in many animal lineages, takes place in ciliates during sexual reproduction, when a new somatic macronucleus develops from a copy of the germline micronucleus. The somatic genomes of numerous Paramecium species are being sequenced and annotated. ParameciumDB integrates the genomes as they become available, to provide resources for functional and comparative genomics to the community. ParameciumDB interfaces and tools have been redesigned.

Fulgoromorpha Lists On the Web (FLOW) is an online database that aims to provide an easy-access summary of available biological published primary data on planthoppers (Hemiptera, Fulgoromorpha), a group of major economic importance. It includes information on taxonomy, nomenclature, bibliography, distribution and various associated biological information on host-plants and parasites (including fossils).

The EPSA | ERNICA Registry is to improve the quality of patient care by enabling health care providers to get insight in their outcomes and using the cumulative data from the EPSA registry to conduct scientific research, for example to compare treatments or identify certain risk factors for complications. The EPSA (European Pediatric Surgical Audit) registry contains information on diseases seen in new-born children, like: Hirschsprung’s disease, Congenital Diaphragmatic Hernia, Oesophageal Atresia, Anorectal Malformation, Omphalocele and Gastroschisis. ERNICA is the European Reference Network for rare Inherited and Congenital (digestive and gastrointestinal) Anomalies European Reference Networks and aims to pool together disease-specific expertise, knowledge and resources from across Europe to achieve health goals that may otherwise be unachievable in a single country. ERNICA monitors and evaluates its activities in accordance with the ERN-wide monitoring framework of expert healthcare professionals from specialised healthcare providers across Europe. These networks seek to pool together the expertise available across Europe and concentrate knowledge and resources on rare and/or complex diseases. Each ERN focuses on a particular rare disease area with two diagnostic groups: Malformations of the digestive system (oesophageal diseases, intestinal diseases, intestinal failure and gastroenterological diseases) and Malformations of the diaphragm and abdominal wall (Malformations of the diaphragm and Abdominal wall defects) This standard defines the metadata required to insure availability, versioning and interoperability of the EPSA|ERNICA data.

The International Service of Geomagnetic Indices (ISGI) is in charge of the elaboration and dissemination of geomagnetic indices, and of tables of remarkable magnetic events, based on the report of magnetic observatories distributed all over the planet, with the help of 6 ISGI Collaborating Institutes.

NARCIS provides access to scientific information, including (open access) publications from the repositories of all the Dutch universities, KNAW, NWO and a number of research institutes, which is not referenced in other citation databases.
