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...

Child health care factors such as medical treatment of sick children have direct and indirect effect on childhood mortality. Through international cooperation, a number of countries including Kenya have gathered information on provision of child health services at facility level from periodic Service Provision Assessment (SPA) surveys. Kenya has also gathered information on medical treatment of...

Introduction: Proximal Femoral Nail and Dynamic Hip Screw, both are the accepted implants for the internal fixation of Pertrochanteric fractures. Objectives of the research were to compare the results of proximal femoral nail and dynamic hip screw in terms of functional mobility of the patients and the results would also be compared in terms of operating time, peri-operative blood loss, radiolo...

BACKGROUND Lag screw cut-out failure following fixation of unstable intertrochanteric fractures in osteoporotic bone remains an unsolved challenge. This study tested if resistance to cut-out failure can be improved by using a dual lag screw implant in place of a single lag screw implant. Migration behavior and cut-out resistance of a single and a dual lag screw implant were comparatively evalua...

BACKGROUND Self-management support is considered to be an essential part of diabetes care. However, the implementation of self-management support within healthcare settings has appeared to be challenging and there is increased interest in "real world" best practice examples to guide policy efforts. In order to explore how different approaches to diabetes care and differences in management struc...
