At least 8% of the human genome is composed of endogenous retrovirus (ERV) sequences. ERVs play a role in placental morphogenesis and can sometimes protect the host against exogenous viruses. On the other hand, ERV reactivation has been found to be associated with different diseases, for example, multiple sclerosis (MS), schizophrenia, type 1 diabetes mellitus (T1D), or amyotrophic lateral scle...
This letter is in response to the article by Riera et al. entitled “Early repolarization variant: Epidemiological aspects, mechanism, and differential diagnosis” The article is available online as in press article Cardiology Journal 2008 (vol. 15). With much interest I read the review article by Riera et al. [1] in which they comprehensively described the epidemiological aspects, mechanism, and...
Retroviruses have been infecting mammals for at least 100 million years, leaving descendants in host genomes known as endogenous retroviruses (ERVs). The abundance of ERVs is partly determined by their mode of replication, but it has also been suggested that host life history traits could enhance or suppress their activity. We show that larger bodied species have lower levels of ERV activity by...
Prolonged inspiratory to expiratory (I:E) ratio ventilation has been researched to reduce lung injury and improve oxygenation in surgical patients with one-lung ventilation (OLV) or carbon dioxide (CO2) pneumoperitoneum. We aimed to confirm the efficacy of the 1:1 equal ratio ventilation (ERV) compared with the 1:2 conventional ratio ventilation (CRV) during surgical procedures. Electronic data...
We examine the Economic Policy Uncertainty (EPU) transmission over Exchange Rate Volatility (ERV) for 8 Emerging Market Economies (EME) using recent panel VAR methodology of Abrigo and Love (Stata Journal 16:778–804, 2016). The econometric investigation reveals that: (a) both domestic US-EPU shocks exert positive effects on ERV, (b) contribution to ERV fluctuations overcomes own EPU’s share, (c...
MOTIVATION Endogenous retrovirus (ERV) elements have been shown to contribute promoter sequences that can initiate transcription of adjacent human genes. However, the extent to which retroviral sequences initiate transcription within the human genome is currently unknown. We analyzed genome sequence and high-throughput expression data to systematically evaluate the presence of retroviral promot...
BACKGROUND The link between concentrations of particulate matter (PM) and respiratory morbidity has been investigated in numerous studies. OBJECTIVES The aim of this study was to analyze the role of different particle size fractions with respect to respiratory health in Beijing, China. METHODS Data on particle size distributions from 3 nm to 1 µm; PM10 (PM ≤ 10 µm), nitrogen dioxide (NO(2))...
Endogenous retroviruses (ERV), or the remnants of past retroviral infections that are no longer active, are found in the genomes of most vertebrates, typically constituting approximately 10% of the genome. In some vertebrates, particularly in shorter-lived species like rodents, it is not unusual to find active endogenous retroviruses. In longer-lived species, including humans where substantial ...
CONTEXT Cardiogenic shock (CS) is the leading cause of death for patients hospitalized with acute myocardial infarction (AMI). OBJECTIVE To assess the effect of early revascularization (ERV) on 1-year survival for patients with AMI complicated by CS. DESIGN The SHOCK (Should We Emergently Revascularize Occluded Coronaries for Cardiogenic Shock) Trial, an unblinded, randomized controlled tri...
Endometrial carcinoma (EnCa) is the most common invasive gynaecologic carcinoma. Over 85% of EnCa are classified as endometrioid, expressing steroid hormone receptors and mostly involving pathological prestages. Human endogenous retroviruses (ERV) are chromosomally integrated genes, account for about 8% of the human genome and are implicated in the etiology of carcinomas. The majority of ERV en...
