the pain is the most common complaint in various diseases. postoperative pain is common complication and spatially in elderly patient because of exacerbation of heard and vessel was impotents. the aim of this study was evaluation of the effect of low-dose iv dexamethasone on postoperative pain in patients with lumbar discectomy.   in a clinical trial that studied in neurosurgery wards of shohad...

The Drosophila gene vasa (vas) encodes an RNA-binding protein required for embryonic patterning and germ cell specification. In vas mutants, translation of several germline mRNAs is reduced. Here we show that VAS interacts directly with the Drosophila homolog of yeast translation initiation factor 2, encoded by a novel gene, dIF2. Embryos produced by vas/+; dIF2/+ females have pattern defects a...

Vasa (Vas) is a conserved DEAD-box RNA helicase expressed in germline cells that localizes to a characteristic perinuclear structure called nuage. Previous studies have shown that Vas has diverse functions, with roles in regulating mRNA translation, germline differentiation, pole plasm assembly, and piwi-interacting RNA (piRNA)-mediated transposon silencing. Although vas has also been implicate...

In zebrafish, maternally produced vasa (vas) transcripts become targeted to the cleavage planes of early embryos and subsequently incorporated into the primordial germ cells (PGCs). Zygotic vas transcription occurs from the onset of gastrulation. Here, we report on the characterisation of the zebrafish vas locus. The gene consists of 27 exons, spans about 25kb, and contains two CpG-rich regions...

UNLABELLED This article presents the responsiveness results of the Erectile Function Visual Analog Scale (EF-VAS) and reports, for the first time, utilities associated with erectile dysfunction (ED), as calculated by a disease-specific utility assessment. The EF-VAS is a new quality of life (QoL) instrument specific to ED that combines the strengths of the disease-specific approach to measuring...

STUDY DESIGN Prospective study of patients with chronic back pain from lumbar spine disorders. OBJECTIVE To evaluate the degree of interchangeability of a 100-mm visual analog scale (VAS) and a 5-point verbal rating scale (VRS) for the assessment of pain intensity. SUMMARY OF BACKGROUND DATA The fact that VAS and Likert scales are highly intercorrelated does not mean that both types of scal...
