BACKGROUND: Spermatogenesis is a complex biological process that requires a highly specialized control of gene expression.In the past decade, small non-coding RNAs have emerged as critical regulators of gene expression both at the transcriptional and post-transcriptional level.DICER1, an RNAse III endonuclease, is essential for the biogenesis of se
Molecular phylogenetic studies have revealed the growing diversity of bat trypanosomes.Here, 14 isolates from blood samples of the vampire bat Desmodus rotundus (Phyllostomidae) from Rio de Janeiro, Southeast Brazil, were cultivated, and morphologically and molecularly characterized.All isolates represent a novel species named Trypanosoma madeirae

Abstract The complex of spaceflight factors has a significant impact on the immunity functional activity.This influence is probably caused by factors such as isolation, monotony, physical inactivity, sensory deprivation, and increased psycho-emotional tension.Long-term wintering at polar stations can be the ground-based model that is most similar t
Age related hearing loss (presbycusis) is one of the most common sensory deficits in the aging population.The main subjective ailment in the elderly is the deterioration of speech understanding, especially in a noisy environment, which cannot solely be explained by increased hearing thresholds.The examination methods used in presbycusis are primari
