LONG-TERM EXPERIMENTAL EVOLUTION REVEALS PURIFYING SELECTION ON PIRNA-MEDIATED CONTROL OF TRANSPOSABLE ELEMENT EXPRESSION

Long-term experimental evolution reveals purifying selection on piRNA-mediated control of transposable element expression

Abstract Recovery - Coaching Background Transposable elements (TEs) are an almost universal constituent of eukaryotic genomes.In animals, Piwi-interacting small RNAs (piRNAs) and repressive chromatin often play crucial roles in preventing TE transcription and thus restricting TE activity.Nevertheless, TE content varies widely across eukaryotes and

Cardiac Index by Transthoracic Echocardiography (CITE) study.

AimsLeft ventricular ejection fraction (LVEF) is the most frequently used parameter in the assessment of heart failure (HF).Cardiac index (CI) is considered a potential alternative to LVEF despite limited evidence.We aimed to assess and compare the predictive accuracy of LVEF and echocardiographically-assessed CI in HF patients.Methods and resultsA

Identification of two new repetitive elements and chromosomal mapping of repetitive DNA sequences in the fish Gymnothorax unicolor (Anguilliformes: Muraenidae)

Muraenidae is a species-rich family, with relationships among genera and species and taxonomy that have not been completely clarified.Few cytogenetic studies have been conducted on this family, and all of them showed the same diploid chromosome number (2n=42) but with conspicuous karyotypic variation among species.The Mediterranean moray eel Gymnot
