Apical extrusion of intracanal bacteria following use of two engine-driven instrumentation techniques
(WILEY, 2005)
Aim To evaluate the number of bacteria extruded apically from extracted teeth ex vivo after canal instrumentation using the two engine-driven techniques utilizing nickel-titanium instruments (ProTaper and System GT). ...
Flotation and entrainment behavior of minerals in talc-calcite separation
(BLACKWELL PUBLISHING, 2005)
The main aim of a flotation process is to recover the valuable part of the ore with minimum gangue contamination by different mechanisms, such as entrainment. In this study, the flotation rate and recovery of talc and ...

Electric field and intense laser field effects on the intersubband optical absorption in a graded quantum well
(IOP PUBLISHING LTD, 2005)
The laser field dependence of the intersubband optical absorption in a graded quantum well (GQW), under an applied electric field is calculated in the effective mass approximation. We have theoretically shown that, in the ...
The effects of therapeutic ultrasound on heart rate variability: A placebo controlled trial
(ELSEVIER SCIENCE INC, 2005)
The effect of therapeutic ultrasound (US) on nervous system is controversial and the effect on autonomic nervous system is not clear. Therefore, the present placebo-controlled trial was planned to investigate the effects ...
Early enteral feeding in newborn surgical patients

Objective: We report the results of a multicenter prospective trial of early enteral trophic feeding in a group of 56 neonates who required abdominal surgery for a variety of congenital anomalies. Methods: In this clinical ...
Posterior fixation of thoracolumbar burst fracture - Short-segment pedicle fixation versus long-segment instrumentation
(LIPPINCOTT WILLIAMS & WILKINS, 2005)
Objective: The treatment of thoracolumbar burst fracture is a controversial issue. Short-segment (SS) pedicle fixation has become a popular treatment option. However, there are several studies regarding the high rate of ...
Ab initio molecular structure study of alkyl substitute analogues of Alzheimer drug phenserine: structure-activity relationships for acetyl- and butyrylcholinesterase inhibitory action
(ELSEVIER SCIENCE BV, 2005)
Considerable experimental evidence suggests that phenserine and some alkyl analogues show inhibitory action against human acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The electronic structure of the newly ...
The lamp effect of laser Doppler flowmetry on teeth
(WILEY, 2005)
The aim of this study is to analyse the intra and extracoronal scattering of laser light. Twelve vital teeth from 12 volunteer individuals (aged 22-29 years) were used. The camera removing the charge coupled device's ...
