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...

Study Design: This retrospective, non-randomized study was designed to evaluate one-year clinical outcomes in a cohort of patients treated with an amniotic suspension allograft as an adjunct to lumbar interbody fusion. Methods: A single-center chart review was conducted to collect preoperative and peri-operative data for patients at or beyond the one year post-operative time point. Results: Pat...

In some statistical process monitoring applications, quality of a process or product is described by more than one ordinal factors called ordinal multivariate process. To show the relationship between these factors, an ordinal contingency table is used and modeled with ordinal log-linear model. In this paper, a new control charts based on ordinal-normal statistic is developed to monitor the ord...
