Orthodontic mechanotherapy encompasses the use of several archwlres during specific stages of treatment. Stainless steel, Nickel titanium (NITI), thermally activated Nickel titanium (CuNiTi), & b titanium (TMA) wires are the ones predominantly In use. The efficiency of sliding mechanics depends upon minimizing friction at the bracket arch wire interface. Friction may be Influenced by several fa...

BACKGROUND Bone scintigraphy including Single Photon Emission Computed Tomography (SPECT) is known for its role in the diagnosis of low back pain disorders. Positron Emission Tomography (PET) with (18)F (Flouride-18) as a tracer can be used to carry out bone scans with improved image quality. With the addition of CT, simultaneous PET/CT fused images provide more accurate anatomical details. The...

Background & Aims: Secondary caries is one of the most common problems in restorative dentistry. The release of flouride ions could substantially benefit the tooth enamel and neigboring dentin because flourid can combat caries. The purpose of this in vitro study was to evaluate the solubility rate and release of fluoride from tooth-colored restorative materials (Iono CID, Fuji II LC, FugiIX, Fu...

Background and Objectives: One of the problems in juice membrane clarification is the accumulation and deposition of rejected compounds on membrane surfaces or inside its pores which results in a membrane fouling. Materials and Methods: Several parameters can have influence on fouling in one hand and prediction of juice permeates flux during the membrane processing is of importance in indust...

Although some still describe the problem as “people eat to...

We report here the purification and mechanistic characterization of a 5′-3′ exonuclease associated with DNA polymerase R from the yeast Saccharomyces cereVisiae. Earlier, we identified a 5′ f 3′ exonuclease activity that copurified with yeast DNA polymerase R-primase in a multiprotein complex [Biswas, E. E., et al. (1993) Biochemistry, 32, 3020-3027]. Peptide sequence analysis of the purified 4...

Previous investigations have established that electrical activity or chronic depolarization influences the development of neonatal rat sympathetic neurons in dissociated cell culture. Depolarization reduces their ability to respond to a cholinergic inducing factor produced by non-neuronal cells, allowing normal adrenergic differentiation to proceed (Walicke, P., R. Campenot, and P. Patterson (1...
