The genetic diversity of eggplant mottled dwarf virus (EMDV), a member of the family Rhabdoviridae, was studied using isolates collected from different herbaceous and woody plant species and remote geographic areas. Sequences ...

Identification of a prospective early motor progression cluster of Parkinson's disease: Data from the PPMI study

Vavougios G.D., Doskas T., Kormas C., Krogfelt K.A., Zarogiannis S.G., Stefanis L. (2018)

Aim: The aim of our study is to phenotype PD motor progression, and to detect whether serum, cerebrospinal fluid (CSF), neuroimaging biomarkers and neuropsychological measures characterize PD motor progression phenotypes. ...

Microbial diversity in biodeteriorated Greek historical documents dating back to the 19th and 20th century: A case study

Karakasidou K., Nikolouli K., Amoutzias G.D., Pournou A., Manassis C., Tsiamis G., Mossialos D. (2018)

Paper documents in archives, libraries, and museums often undergo biodeterioration by microorganisms. Fungi and less often bacteria have been described to advance paper staining, so called “foxing” and degradation of paper ...

NAP: The Network Analysis Profiler, a web tool for easier topological analysis and comparison of medium-scale biological networks

Theodosiou T., Efstathiou G., Papanikolaou N., Kyrpides N.C., Bagos P.G., Iliopoulos I., Pavlopoulos G.A. (2017)

Objective: Nowadays, due to the technological advances of high-throughput techniques, Systems Biology has seen a tremendous growth of data generation. With network analysis, looking at biological systems at a higher level ...

NAT/NCS2-hound: a webserver for the detection and evolutionary classification of prokaryotic and eukaryotic nucleobase-cation symporters of the NAT/NCS2 family

Chaliotis A., Vlastaridis P., Ntountoumi C., Botou M., Yalelis V., Lazou P., Tatsaki E., Mossialos D., Frillingos S., Amoutzias G.D. (2018)

Nucleobase transporters are important for supplying the cell with purines and/or pyrimidines, for controlling the intracellular pool of nucleotides, and for obtaining exogenous nitrogen/carbon sources for metabolism. ...

Pancultural nostalgia: Prototypical conceptions across cultures

Hepper, E. G.; Wildschut, T.; Sedikides, C.; Ritchie, T. D.; Yung, Y. F.; Hansen, N.; Abakoumkin, G.; Arikan, G.; Cisek, S. Z.; Demassosso, D. B.; Gebauer, J. E.; Gerber, J. P.; González, R.; Kusumi, T.; Misra, G.; Rusu, M.; Ryan, O.; Stephan, E.; J. Vingerhoets, A. J.; Zhou, X. (2014)

Nostalgia is a frequently experienced complex emotion, understood by laypersons in the United Kingdom and United States of America to (a) refer prototypically to fond, self-relevant, social memories and (b) be more pleasant ...
