GMS Hygiene and Infection Control, 2014 [english] Aim: During the last decade it became obvious that viruses belonging to and families (order Megavirales), may be potential causative agents of pneumonia. Thus, we have performed a review of the association of , , and virophages with pneumonia,

Microvesicles and intercellular communication in the context of parasitism [PDF]
, 2013 There is a rapidly growing body of evidence that production of microvesicles (MVs) is a universal feature of cellular life. MVs can incorporate microRNA (miRNA), mRNA, mtDNA, DNA and retrotransposons, camouflage viruses/viral components from immune ...

Evolution of exploitation and replication of giant viruses and virophages. [PDF]
Virus EvolAbstract Tripartite biotic interactions are inherently complex, and the strong interdependence of species and often one-sided exploitation can make these systems vulnerable to extinction. The persistence of species depends then on the balance between exploitation and avoidance of exploitation beyond the point where sustainable resource ...

A systematic approach to cancer: evolution beyond selection
Clinical and Translational Medicine, Volume 6, Issue 1, December 2017., 2017 AbstractCancer is typically scrutinized as a pathological process characterized by chromosomal aberrations and clonal expansion subject to stochastic Darwinian selection within adaptive cellular ecosystems. Cognition based evolution is suggested as an alternative approach to cancer development and progression in which neoplastic cells of differing ...

Polinton-like viruses are abundant in aquatic ecosystems
Microbiome, 2021 Background Polintons are large mobile genetic elements found in the genomes of eukaryotic organisms that are considered the ancient ancestors of most eukaryotic dsDNA viruses.

The Common Ancestor of Archaea and Eukarya Was Not an Archaeon
Archaea, Volume 2013, Issue 1, 2013., 2013 It is often assumed that eukarya originated from archaea. This view has been recently supported by phylogenetic analyses in which eukarya are nested within archaea. Here, I argue that these analyses are not reliable, and I critically discuss archaeal ancestor scenarios, as well as fusion scenarios for the origin of eukaryotes.

Characteristics of virophages and giant viruses
Acta Biochimica Polonica, 2018 Five years after being discovered in 2003, some giant viruses were demonstrated to play a role of the hosts for virophages, their parasites, setting out a novel and yet unknown regulatory mechanism of the giant viruses presence in an aqueous. So far, 20 virophages have been registered and 13 of them have been described as a metagenomic material, which ...

Metagenomic Analysis of Virus Diversity and Relative Abundance in a Eutrophic Freshwater Harbour
Viruses, 2019 Aquatic viruses have been extensively studied over the past decade, yet fundamental aspects of freshwater virus communities remain poorly described. Our goal was to characterize virus communities captured in the >0.22 µm size-fraction seasonally ...

Epigenetic Influences of Mobile Genetic Elements on Ciliate Genome Architecture and Evolution [PDF]
, 2022 Mobile genetic elements (MGEs) are transient genetic material that can move either within a single organism\u27s genome or between individuals or species.
