Doubled haploid (DH) populations are useful to scientists and breeders in both crop improvement and basic research. Current methods of producing DHs usually need in vitro culture for extracting haploids and chemical treatment for chromosome doubling. This report describes a simple method for synthesizing DHs (SynDH) especially for allopolyploid species by utilizing meiotic restitution genes. Th...

Dapsone hypersensitivity syndrome (DHS) can be classified as a ‘drug reaction with eosinophilia and systemic symptoms’ (DRESS). It has a variable course, it is not dose dependent and may present with different clinical and laboratory abnormalities. In some cases it may be fatal. We describe a 31 year old man with lepromatous leprosy in whom DHS developed 4 weeks after initiation of World Health...

Abstract Introduction The goal of treatment an intertrochanteric femoral fracture is restoration patient's mobility as early possible. dynamic hip screw (DHS) has been used for several decades to treat these fractures. Proximal nails (PFN) are reported have advantage in such This study aims at comparing the results unstable fractures femur treated with PFN and DHS. Method was a prospective, ran...

BACKGROUND There has been limited work comparing survey characteristics and assessing the quality of child anthropometric data from population-based surveys. OBJECTIVE To investigate survey characteristics and indicators of quality of anthropometric data in children aged 0-59 months from 23 countries in the West Central Africa region. METHODS Using established methodologies and criteria to ...

By specializing in preventative oral healthcare, dental hygienists (DHs) have the potential to improve oral health in the United States. DHs decrease the cost and increase the availability of oral healthcare beyond what would be provided by dentists alone. Yet laws and regulations in many U.S. states prevent DHs from fulfilling their potential. A prior study by Wing et al. (2005) found that sta...

Pyrrolizidine alkaloids (PAs) are constitutive plant defense compounds with a sporadic taxonomic occurrence. The first committed step in PA biosynthesis is catalyzed by homospermidine synthase (HSS). Recent evidence confirmed that HSS evolved by gene duplication from deoxyhypusine synthase (DHS), an enzyme involved in the posttranslational activation of the eukaryotic translation initiation fac...

The Department of Homeland Security (DHS) is adjusting the fee schedule for immigration and naturalization benefit requests processed by U.S. Citizenship and Immigration Services (USCIS). The fee schedule was last adjusted on November 23, 2010. USCIS conducted a comprehensive fee review for the fiscal year (FY) 2016/2017 biennial period and determined that current fees do not recover the full c...

Previous experiments with Saccharomyces cerevisiae had suggested that diacylglycerol-containing glycosylphosphatidylinositols (GPIs) are added to newly synthesized proteins in the endoplasmic reticulum (ER) and that ceramides subsequently are incorporated into GPI proteins by lipid remodeling. Here we prove this hypothesis by labeling yeast cells with [3H]dihydrosphingosine ([3H]DHS) and showin...

the effect of salinity on organic removal and ammonium oxidation in a down-flow hanging sponge reactor was investigated by conducting a long-term continuous experiment over a period of 800 days. the dhs reactor, constructed by connecting three identical units, was fed with artificial wastewater containing 500 mg-n/l of ammonium nitrogen and 1400 mg- cod/l of phenol. salinity of the influent was...

The biological function of the post-translational modification hypusine in the eukaryotic initiation factor 5A (EIF-5A) in eukaryotes is still not understood. Hypusine is formed by two sequential enzymatic steps at a specific lysine residue in the precursor protein EIF-5A. One important biological function of EIF-5A which was recently identified is the translation of polyproline-rich mRNA, sugg...
