background: assessment of uterine abnormalities is a core part in infertility evaluation. objective: the aim of this study was to evaluate the sensitivity and specificity of three-dimensional hysterosonography (3-dhs) in the diagnosis of uterine abnormalities in infertile women. materials and methods: the infertile women who visited royan institute and referred to 3-dhs consecutively, prior to ...

Dynamic hip screw (DHS) is a well-established conventional implant for treating intertrochanteric fracture. However, revision surgery sometimes still occurs due to the cutting out of implants. A helical blade instead of threaded screw (DHS blade) was designed to improve the fixation power of the osteoporotic intertrochanteric fracture. In this study, the biomechanical properties of DHS blade co...

BACKGROUND Dental hygienists (DHs) in Ireland have a choice regarding undertaking further training to update their skills to the current scope of practice. No data exists in relation to how many DHs have updated their skills, how often they use these new skills and how confident they are in using them. PURPOSE OF THE STUDY To identify the percentage of DHs who have the full range of skills cu...

DNase I hypersensitive (DHS) sites are important for understanding cis regulation of gene expression. However, existing methods for detecting DHS sites in small numbers of cells can lead to ambiguous results. Here we describe a simple new method, in which DNA fragments with ends generated by DNase I digestion are isolated and used as templates for two PCR reactions. In the first PCR, primers ar...

Ischemic postconditioning and remote conditioning are potentially useful tools for protecting ischemic myocardium. This study tested the hypothesis that 2,3-dehydrosilybin (DHS), a flavonolignan component of Silybum marianum, could attenuate cardiomyocyte damage following hypoxia/reoxygenation by decreasing the generation of reactive oxygen species (ROS). After 5-6 days of cell culture in normo...

OBJECTIVE To Study the incidence and clinical characteristics of dapsone hypersensitivity syndrome (DHS) among MDT-treated leprosy patients from 2006 to 2009 in China. METHODS A retrospective survey was carried out throughout China using a specially designed questionnaire. RESULTS From 2006 to 2009, there were 63 new patients reported to have DHS with an incidence of 1.0%. Among these patie...

The effects of suppressing deoxyhypusine synthase (DHS) have been examined in tomato (Solanum lycopersicum cv UCT5). DHS mediates the first of two sequential enzymatic reactions that activate eukaryotic translation initiation factor-5A (eIF-5A) by converting a conserved Lys to the unusual amino acid, deoxyhypusine. DHS protein levels were suppressed in transgenic plants by expressing the 3'-unt...

The purpose of this study was to determine whether use of an air ambulance service using a helicopter with a critical care physician and nurse on board (doctor helicopter service; DHS) could shorten the prehospital delay. We evaluated the initial treatment time and the transport time in 30 patients transported by DHS and 30 patients transported by ground ambulance service (GAS). The initial tre...
