The mucosa that covers the residual ridges of edentulous patients may present some distortion or displacement when occlusal loading is applied in complete dentures. This distortion and movement of the denture can result in acceleration of residual ridge resorption and loss of retention and stability. The aim of this study was to analyze the pattern of upper complete denture movement related to ...

The purpose of this study was to characterize methylmercury (MeHg)-induced dopamine (DA) release from undifferentiated pheochromocytoma (PC12) cells and to examine the potential role for DA synthesis in this process. MeHg caused a significant increase in DA release that was both concentration- and time-dependent. DA release was significantly increased by 2µM MeHg at 60min and by 5µM MeHg at 30m...
The operation of DA NE, the 1.02 GeV c.m. e + e collider of the Frascati National Laboratory with the KLOE experimental detector was successfully concluded in March 2006. Since April 2004 it delivered a luminosity > 2 fb -1 on the peak of the resonance, > 0.25 fb -1 off peak and a high statistics scan of the resonance. The best peak luminosity obtained during this run was 1.5 10 32 cm -2 s -1 ,...
The effect of substances which alter extracellular dopamine (DA) concentration has been studied by measuring changes in the binding of radiolabelled raclopride, a DA D2 receptor ligand that is sensitive to endogenous DA. To better characterize the relationship between extracellular DA concentration and DA D2 receptor binding of raclopride, we compared the changes of extracellular DA concentrati...
the combinations of inductively coupled plasma-optical emission spectrometry (icp-oes) and three classification algorithms, i.e., partial least squares discriminant analysis (pls-da), least squares support vector machine (ls-svm) and soft independent modeling of class analogies (simca), for discriminating different brands of iranian bottled mineral waters, were explored. icp-oes was used for th...
in this study an ultra-broad band, low-power, and high-gain cmos distributed amplifier (cmos-da) utilizing a new gain-cell based on the inductively peaking cascaded structure is presented. it is created bycascading of inductively coupled common-source (cs) stage and regulated cascode configuration (rgc).the proposed three-stage da is simulated in 0.13 μm cmos process. it achieves flat and high ...
dynamic assessment (da) which is rooted in vygotsky’s (1978) sociocultural theory involves the integration of instruction and assessment in a dialectical way to achieve two main purposes: enhancing learners' development and understanding about their learning potential. however, the feasibility and appropriateness of mediation are two main concerns of da. the former is concerned with the applica...
An electrophysiological study was performed to investigate the effects of cis-N-[4-[4-(1,2-benz-isozole-3-yl)-1-piperazinyl]butyl]cyclohexan e-1,2-dicarboximide hydrochloride (perospirone), a novel antipsychotic agent with high affinities for D2/5-HT2-receptors, on the dopaminergic (DA) neurons in the ventral tegmental area (VTA) using chloral hydrate-anesthetized rats. DA neurons and non-DA ne...
Mice that cannot make dopamine (DA), a condition caused by the selective inactivation of tyrosine hydroxylase in dopaminergic neurons, are born normal but gradually become hypoactive and hypophagic, and die at 3 weeks of age. We characterized the feeding and locomotor responses of these DA-deficient (DA-/-) mice to 3, 4-dihyroxy-L-phenylalanine (L-DOPA) to investigate the relationship between b...
