In recent years considerable attention has been paid to the elucidation of pathways of carbohydrate breakdown differing from that of the well-known Embden-Meyerhof-Parnas (EMP) scheme. Although it is recognized that the stepwise oxidation of glucose via gluconate with or without preliminary phosphorylation is an important means by which a number of aerobic bacteria obtain their energy (Barron a...

BACKGROUND Caries process is not a static one, but is dynamic with interspersed periods of demineralization and remineralization of enamel, intimately related and occurs episodically based upon the presence of cariogenic bacteria in dental plaque and the availability of refined carbohydrates for fermentation to organic acids. OBJECTIVES Early enamel caries could be reversed with avoidance of ...

ABSTRACTIntroduction Caries initiation is associated with demineralization of the toothenamel surface. Calcium and phosphorous are lost from subsurface enamel, resultingin formation a lesion. Aim: this study aimed to investigate comparethe enamel surface ultramorphology minerals content by Environmental ScanningElectron Microscope (ESEM) Energy dispersive x-ray spectroscopy (EDX) toassess micro...

Natural nanomaterial; Montmorillonite Clay was collected and purified and then applied in the removal of Fluoride. The Montmorillonite Clay was grounded and 150g was weighed and refluxed in 500mL 1MHCl at 1200C for one hour thirty minutes and activated Montmorillonite Clay was obtained. Flouride was determined with the aid of SPADNS Reagent (2-parasulfophenylazo)-1,8-dihydroxy-3,6-naphthalene d...

High power, high brightness fiber lasers have numerous potential commercial and military applications. These lasers offer unique flexibility as they may be coherently combined to provide a potential multi-kilowatt laser source and integrated delivery system. Fiber lasers with cladding pump designs represent a new generation of diode pumped configurations that are extremely efficient, have singl...

BACKGROUND The DeVilbiss 40 glass hand held nebulisers have been widely used for airways responsiveness testing in epidemiological surveys of asthma. These nebulisers have been superseded in some recent studies by the DeVilbiss 45 plastic hand held nebulisers with the assumption that they are interchangeable. This study compared the aerosol outputs of the DeVilbiss 40 and DeVilbiss 45 nebuliser...

OBJECTIVES To compare glucose values obtained using sodium flouride (NaF) tubes and serum separation tubes (SST) in a tertiary care hospital laboratory setting. METHODS This study was conducted at the Clinical Biochemistry Laboratory, Royal Hospital, Oman. During the study period (1 September-30 November 2013), 50 pairs (one NaF tube and one SST) of patient's blood specimens were randomly col...
