The DEAD-box RNA helicase Vasa (Vas) is required for germ cell development and function, as well as for embryonic somatic posterior patterning. Vas interacts with the general translation initiation factor eIF5B (cIF2, also known as dIF2), and thus may regulate translation of specific mRNAs. In order to investigate which functions of Vas are related to translational control, we have analyzed the...

BACKGROUND Olfactory dysfunction, including anosmia and hyposmia is difficult to treat. Although the mechanism is not well known, stellate ganglion block (SGB) is used to treat olfactory dysfunction. There are no prior studies on the long-term effects of SGB on olfactory dysfunction. The purpose of this study was to evaluate the continuity of therapeutic effects and patient satisfaction with SG...

BACKGROUND Idiopathic left ventricular arrhythmias (VAs) and those caused by structural heart disease can originate from the papillary muscles, fascicles, and mitral annulus. Differentiation of these arrhythmias can be challenging because they present with a right bundle branch block morphology by electrocardiography. We sought to identify clinical, electrocardiographic, and electrophysiologica...

BACKGROUND Proximal humeral fractures are common in older patients. The majority are minimally displaced and are associated with good outcomes after nonoperative treatment. Poorer outcomes are associated with displaced, multipart fractures. There is no clear benefit from surgical fracture fixation compared to nonoperative treatment. Replacement of the fractured humeral head with a hemiarthropla...

BACKGROUND Proximal humerus fracture is the third most common fracture type after hip and distal radius fracture in elderly patients. A comprehensive study by Palvanen et al. demonstrated an increase in the annual fracture rate of 13.7% per year over the past 33 years. Should this trend continue, the fracture rate would triple over the next three decades. The increasing incidence of low-energy ...

Cucumisin is a thermostable alkaline serine protease that is found in the juice of melon fruits (Cucumis melo L.). We have determined the complete nucleotide sequence of a cucumisin cDNA (2,552 nucleotides) and deduced the corresponding amino acid sequence. The open reading frame of the cDNA consists of 731 codons and encodes a large precursor (molecular weight, 78,815) relative to the observed...

This paper critically reviews theoretical and empirical propositions regarding visual analogue scale (VAS) valuations of health states and their use in cost-utility analysis (CUA). A widely repeated assertion in the economic evaluation literature is the inferiority, on theoretical grounds, of VAS valuations. Five common criticisms are: VAS lacks a theoretical foundation; VAS values are not 'cho...

BACKGROUND Congenital absence of the vas deferens is an important cause of obstructive azoospermia, and the lack of an imaging diagnostic test is a critical problem. The aim of this study is to discuss the use of ultrasonography in congenital absence of vas deferens, including dysplasia of the epididymis and the seminal vesical. MATERIAL AND METHODS Five fresh spermatic cord specimens were dete...

objective: to determine bilateral effects of unilateral iatrogenic vas deferens trauma (uit) on epididymal sperm characteristics and in vitro fertilizing capacity in an experimental mouse model. methods: experiments were performed on three equal groups each comprising six adult male mice. following anaesthesia, uit was induced by clamping left vas deferens with a mosquito clamp in fully locked ...

background measuring health status by using standardized and validated instrument has become a growing concern over the past few decades throughout the developed and developing countries. the aim of the study was to investigate the overall self-reported health status along with potential inequalities by using euroqol 5 dimensions (eq-5d) instrument among low-income people of bangladesh.   me...
