Endogenous retroviruses (ERVs) are a class of transposable elements found in all vertebrate genomes that contribute substantially to genomic functional and structural OPEN ACCESS Computation 2014, 2 222 diversity. A host species acquires an ERV when an exogenous retrovirus infects a germ cell of an individual and becomes part of the genome inherited by viable progeny. ERVs that colonized ancest...
LTR retrotransposons are repetitive DNA elements comprising ∼10% of the human genome. However, LTR sequences are disproportionately present in human long, non-coding RNAs (lncRNAs). Whether and how the LTR lncRNAs serve biological functions are largely unknown. Here we show that in primary human erythroblasts, lncRNAs transcribed from the LTR retrotransposons of ERV-9 human endogenous retroviru...
Providing effective support for group awareness is a critical requirement of synchronous collaborative authoring tools. This paper reports our work on developing new awareness mechanisms including Extended Radar View (ERV) and Modification Director (MD) for CoWord, a synchronous collaborative authoring tool that is developed based on Microsoft Word. ERV supports awareness for collaborative auth...
We show that reasoning in the temporal conceptual model ERV T , a fragment of ERV T that only allows timestamping is complete for 2-ExpTime. The membership result is based on an embedding of the conceptual model into the description logic S5ALCQI . Hardness is obtained by reducing a fragment of S5ALCQI , namely S5ALC with global roles only, to ERV T .
Surveillance of incident influenza-like illness (ILI) was implemented in two children and adult medical emergency departments during the influenza A (H1/N1) pandemic to assess correlations in the daily number of ILI-related emergency room visits (ERV) between these departments. A total of 7165 ILIs in children and 610 ILIs in adults were observed. We noticed a high linear correlation between th...
Endogenous retroviruses (ERVs) are vertically transmitted intragenomic elements derived from integrated retroviruses. ERVs can proliferate within the genome of their host until they either acquire inactivating mutations or are lost by recombinational deletion. We present a model that unifies current knowledge of ERV biology into a single evolutionary framework. The model predicts the possible l...
BACKGROUND There has not been a detailed description of expiratory reserve volume (ERV) during slow expiration with glottis open in infralateral decubitus position (ELTGOL, for Expiration Lente Totale Glotte Ouverte en infraLatéral) and its reproducibility. The aim of this study was to determine ERV during ELTGOL and to evaluate ERV intra-observer and inter-observer reliability. METHODS In th...
Endogenous retroviruses (ERVs) comprise a significant percentage of the mammalian genome, and it is poorly understood whether they will remain as inactive genomes or emerge as infectious retroviruses. Although several types of ERVs are present in domestic cats, infectious ERVs have not been demonstrated. Here, we report a previously uncharacterized class of endogenous gammaretroviruses, termed ...
Some murine-endogenous retroviruses, making up ∼10 % of the mouse genome, are induced during the course of experimental sepsis in which lipopolysaccharide (LPS), a pathogenic component of gram-negative bacteria, often plays a critical role. In this study, we investigated whether LPS stress induces the production of murine leukemia virus type-endogenous retrovirus (MuLV-ERV) virions in primary l...
Human endogenous retroviruses (ERV) are an integral part of our genome. Expression of ERV is usually switched off but reactivation of ERV has been observed in varying human diseases including cancer. Recently, reactivation of ERV associated promoters in Hodgkin's lymphoma (HL) cells has been described. Despite relatively good prognosis, not all patients with HL can be cured with the established...
