Genetic polymorphisms of GSTs and their association with primary brain tumor incidence
(ELSEVIER SCIENCE INC, 2005)
Glutathione S-transferases GSTM1, GSTT1, and GSTP1 are phase II biotransformation enzymes that function on detoxification of a wide range of exogenous agents including carcinogens. It has been shown that genetic variations ...
Coronary collateral circulation: Any effect on P-wave dispersion?
(SAGE PUBLICATIONS INC, 2008)
Coronary collateral circulation determines the severity of ischemic myocardial damage. Increased P-wave dispersion is an independent predictor for atrial fibrillation. Consistent evidence is little about the relation between ...
Shallow-water foraminiferal assemblages and microfacies of the Danian-Lutetian sequences in the Bolu region (Northwestern Turkey)
(PLEIADES PUBLISHING INC, 2005)
The Paleocene and Eocene sediments of Bolu region were studied with respect to benthic foraminiferal stratigraphy and microfacies. In general, the Paleocene and Maastrichtian successions have conform contacts except for a ...
The evolution of travertine masses in the Sivas area (Central Turkey) and their relationships to active tectonics
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2008)
Sicak Cermik, Delikkaya and Sarikaya are important travertine fields with active hot springs located 31 km west of Sivas. Based on their morphology, most of the travertines are classified as fissure-ridge travertines. ...
Distribution of N-acetyltransferase type 1 (NAT1) genotypes and alleles in a Turkish population
(SOC BRASIL GENETICA, 2004)
NAT1 is an intronless gene on chromosome 8p21.3 encoding a 290-amino-acid-long protein showing acetyltransferase activity. Some 26 alleles of NAT1 gene have been identified in human populations. In the present study we ...
On Lie ideals with generalized derivations
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2006)
Let R be a prime ring with characteristic different from 2, let U be a nonzero Lie ideal of R, and let f be a generalized derivation associated with d. We prove the following results: (i) If a is an element of R and [a, f ...

Effects of the shape properties of talc and quartz particles on the wettability based separation processes
(ELSEVIER SCIENCE BV, 2004)
Shape properties of talc and quartz particles ground by a laboratory size ball, rod, and autogenous mills were studied using scanning electron microscope (SEM). More than 100 particles were measured to do the shape analysis ...
Comparison of nasal volume changes during rapid maxillary expansion using acoustic rhinometry and computed tomography
(OXFORD UNIV PRESS, 2007)
The purpose of this study was to compare nasal volume changes using acoustic rhinometry (AR) and computed tomography (CT). The subjects were 10 children (6 girls and 4 boys, with an age range of 12-14 years) who required ...
Lack of nitrate tolerance in isosorbid dinitrate- and sodium nitroprusside-induced relaxation of rabbit internal anal sphincter
(BAISHIDENG PUBL GRP CO LTD, 2008)
AIM: To investigate the tolerance development against the relaxant effect of nitric oxide donating drug isosorbide dinitrate (ISDN) and sodium nitropruside (SNP) in internal anal sphincter (IAS) smooth muscle. METHODS: ...
