A comparison of sedation with dexmedetomidine or propofol during shockwave lithotripsy: A Randomized controlled trial
(LIPPINCOTT WILLIAMS & WILKINS, 2008)
BACKGROUND: Dexmedetomidine, because it has both sedative and analgesic properties, may be suitable for conscious sedation during painful procedures. Extracor-Poreal shockwave lithotripsy (ESWL) is a minimal to mildly ...
Validity of the CA125 level in the differential diagnosis of pulmonary tuberculosis
(NATL INST INFECTIOUS DISEASES, 2008)
The aim of the current study was to determine the possible crucial role of cancer antigen 125 (CA125) in the diagnosis of pulmonary tuberculosis (PTB). The CA125 levels of study and control groups were statistically compared. ...
Prediction of the pH and the temperature-dependent swelling behavior of Ca2+-alginate hydrogels by artificial neural networks
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
This paper considers the possibility of using artificial neural network models to identify model for swelling behavior as new techniques. Multi-layer feed-forward, radial basis function and generalized regression neural ...
Computation of flow in a target flowmeter
(NATL INST SCIENCE COMMUNICATION, 2008)
Present study determines optimum geometry for target fluidic flowmeter capable to function at small Reynolds numbers (<300). Using fluent code solver, numerical studies were carried out for gasoil measurements at various ...
Antioxidant potentials and rosmarinic acid levels of the methanolic extracts of Salvia virgata (Jacq), Salvia staminea (Montbret & Aucher ex Bentham) and Salvia verbenaca (L.) from Turkey
(ELSEVIER SCI LTD, 2008)
This study was designed to examine the in vitro antioxidant activities and rosmarinic acid levels of the methanol extracts of Salvia virgata, Salvia staminea and Salvia verbenaca. The extracts were screened for their ...
Analysis of Ki-ras Exon 2 Gene Mutations in 3-Methylcholanthrene and Butylated Hydroxytoluene-Induced Rat Lung Tissues
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2008)
3-Methylcholanthrene (MCA) is a polycyclic aromatic hydrocarbon and potent carcinogenic agent that is often used in experimental cancer studies. Butylated hydroxytoluene (BHT) has been widely used for many years as an ...
A comparative evaluation of the response of platinum and mineral electrodes in sulfide mineral pulps
(ELSEVIER SCIENCE BV, 2008)
The pulp potential of galena, chalcopyrite and pyrite have been measured in parallel with Pt and mineral electrodes by controlling the potential with oxidizing (H2O2 and K2Cr2O7) and reducing (Na2S and Na2S2O4) agents under ...
Relative variation of ionic composition in a karstic lake under the theory of unweighted vs weighted logratio analysis
(IWA PUBLISHING, 2008)
The use of logratio analysis in limnological studies has proved to be effective for solving the problems of the constrained nature of compositional data. The method offers a graphical tool, the relative variation biplot, ...
Nitritation and denitritation of ammonium-rich wastewater using fluidized-bed biofilm reactors
(ELSEVIER SCIENCE BV, 2008)
Fluidized-bed biofilm nitritation and denitritation reactors (FBBNR and FBBDR) were operated to eliminate the high concentrations of nitrogen by nitritation and denitritation process. The dissolved oxygen (DO) concentration ...
Prevalence of common and atypical melanocytic nevi in Turkish children
(JOHN LIBBEY EUROTEXT LTD, 2008)
The incidence of malignant melanoma is increasing rapidly in the white population of the world. Therefore, it is necessary to know the etiological factors of malignant melanoma and to take preventive measures in high-risk ...
