That endogenous retrovirus (ERV) is present within the placenta of humans and other mammals has been known for the past 25 years, but the significance of this observation is still not fully understood. Much molecular biological data have emerged in recent years to support the earlier electron microscopic data on the presence of placental ERV. The evidence for ERV in animal and human placental t...

Human placental endogenous retroviral (ERV) particle isolates were investigated by ultrastructural evaluation. Although retrovirus-like structures in normal human placental tissue sections have been described, the precise nature of these particles has not previously been defined. By direct electron microscopic (EM) observation of placental ERV isolates that display retroviral reverse transcript...

establish the presence of a more ancient ERV component in the murine genome, comprised of isolated, highly degraded insertions. These sequences evidence a transition in murine evolutionary history, beginning about one million years ago, wherein the ancient ERV families that have counterparts in humans and other large mammals were overtaken by a wave of newly acquired and/or transpositionally ac...

We detected 19 complete endogenous retroviruses of the K family in the genome of rhesus monkey (Macaca mulatta; RhERV-K) and 12 full length elements in the genome of the common chimpanzee (Pan troglodytes; CERV-K). These sequences were compared with 55 human HERV-K and 20 CERV-K reported previously, producing a total data set of 106 full-length ERV-K genomes. Overall, 61% of the human elements ...

Early repolarization variant (ERV or ERPV) is a enigmatic electrocardiographic phenomenon, characterized by prominent J wave and ST-segment elevation in multiple leads. Recently, there has been renewed interest in ERV because of similarities to the arrhythmogenic Brugada syndrome (BrS). Not much is known about the epidemiology of ERV and several studies have reported that this condition is asso...

An investigation was undertaken of primate pol gene sequences from a novel endogenous retrovirus family, ERV-W, related to a new human endogenous retrovirus family (HERV-W) that includes multiple sclerosis-associated retrovirus (MSRV) sequences identified in particles recovered from monocyte cultures from patients with multiple sclerosis. The pol gene sequences of the ERV-W family were detected...

We studied the influence of lung volumes on apnoea-induced desaturation in ten subjects with sleep apnoea syndrome. Lung volumes were measured by helium dilution in the sitting and supine position and closing volume with the single-breath nitrogen washout test. To characterize the severity of apnoea-induced desaturations, we determined a desaturation curve for each patient. This curve was obtai...

The present study provides insights into the energy-saving potential of a membrane energy recovery ventilator (ERV) for management building air-conditioning loads. This explores direct (DEC), Maisotsenko cycle (MEC) evaporative cooling, and vapor compression (VAC) systems with ERV. Therefore, this aims to explore possible options in terms temperature, relative humidity, human thermal comfort, w...
