Dehydrosoyasaponin-I (DHS-I) is a potent activator of high-conductance, calcium-activated potassium (maxi-K) channels. Interaction of DHS-I with maxi-K channels from bovine aortic smooth muscle was studied after incorporating single channels into planar lipid bilayers. Nanomolar amounts of intracellular DHS-I caused the appearance of discrete episodes of high channel open probability interrupte...

The minimal fungicidal concentration (MFC) of dihydrosphingosine (DHS), phytosphingosine (PHS), and five short-chain DHS derivatives was determined for Candida albicans and Candida glabrata. In this respect, a C15- and a C17-homologue of DHS showed a 2- to 10-fold decreased MFC as compared to native DHS (i.e. C18-DHS). DHS derivatives that were active, that is, comprising 12, 15, 17, or 18 carb...

AIMS Dietary and herbal supplements (DHS) are commonly used among inpatients and may cause interactions with drugs or other DHS. This study explored whether adverse events were actually associated with such interactions and examined specific characteristics among inpatient DHS users prone to such adverse events. METHODS This was a cross-sectional study of 947 patients hospitalized in 12 depar...

BACKGROUND Delayed bone union, nonunion or osteonecrosis often occur after femoral neck fractures in young adults. Secondary bone healing requires strong internal fixation, intramedullary pressure reduction and early functional exercise. OBJECTIVE To compare bone healing of femoral neck fractures treated with hollow-bone-graft dynamic hip screws (Hb-DHS) and standard dynamic hip screws (DHS) ...

Background and Objectives: One of the data sources for monitoring the progress towards Sustainable Development Goals and Universal Health Coverage (UHC) is household surveys such as Multiple Indicator Cluster Survey (MICS) and Demographic and health Survey (DHS).  This study was conducted to assess the implementation of these surveys in the Eastern Mediterranean Region (EMR) to evaluate the exp...

2,3-dehydrosilybin (DHS) is a minor flavonolignan component of Silybum marianum seed extract known for its hepatoprotective activity. Recently we identified DHS as a potentially cardioprotective substance during hypoxia/reoxygenation in isolated neonatal rat cardiomyocytes. This is the first report of positive inotropic effect of DHS on perfused adult rat heart. When applied to perfused adult r...

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...
