Surface roughness of new microhybrid resin-based composites
(AMER DENTAL ASSOC, 2005)
Background. Rough, poorly polished resin-based composite (RBC) surfaces contribute to staining, plaque accumulation, gingival irritation and recurrent caries. Proper finishing and polishing enhance both the esthetics and ...
Biological denitrification of drinking water in a slow sand filter
(ELSEVIER SCIENCE BV, 2007)
Biological removal of nitrate from drinking water was studied in a slow sand filter. Optimum carbon to nitrogen ratio (C/N) was found to be 1.8 when using acetic acid in batch tests. The filtration rates impact on NO3-N ...
Relationship between FIGO grade and AgNOR, S100-positive Langerhans cells in endometrial adenocarcinoma
(WILEY, 2000)
Cell kinetic information is an important adjuvant to histological grading in some malignant tumors. In the current study, 20 endometrial adenocarcinomas were graded according to the 1988 International Federation of Gynecology ...
Adsorption of methyl violet in aqueous solutions by poly(acrylamide-co-acrylic acid) hydrogels
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)
In this study, Acrylamide(AAm)/Acrylic Acid(AAc) monomer mixtures which contain different quantities of acrylic acid have been irradiated to form hydrogels with gamma-radiation. Acrylamide/Acrylic Acid (AAm/AAc) monomer ...
A basal chalcidoid (Insecta : Hymenoptera) from the earliest Cretaceous or latest Jurassic of Mongolia
(BRILL ACADEMIC PUBLISHERS, 2004)
Khutelchalcis gobiensis gen. et sp. n. (Khutelchalcididae fam. n.), based on a tiny impression fossil collected from the lowermost Cretaceous or uppermost Jurassic deposits of Khutel-Khara in East Mongolia, was studied ...
Mechanism of relaxation induced by nicotine in normal and ovalbumin-sensitized guinea-pig trachea
(ELSEVIER SCIENCE BV, 2007)
Nicotine is an irritant molecule in the cigarette that contributes airway hyper-reactivity. The aim of this study was to investigate the mechanism of these effects and effects of nicotine on the isolated trachea preparations ...
Prevalence of atopy in rheumatoid arthritis in Sivas, Turkey. A prospective clinical study
(SPRINGER HEIDELBERG, 2004)
Assumed mutual antagonism of T-helper cell (Th)1 and Th2 diseases suggests that the prevalence of atopy should be decreased in rheumatoid arthritis (RA). We tried to determine that prevalence. Sixty-two patients with RA ...
Chemical linkage at allosteric activation of E-Coli cAMP receptor protein
(SPRINGER, 2008)
Cyclic AMP Receptor protein (CRP) regulates transcription initiation in E. coli. The ligand and DNA binding data yields the following results: (1) There are two different types of cAMP binding sites; weak and strong. (2) ...
Synthesis and characterization of boron carbide films by plasma-enhanced chemical vapor deposition
(TAYLOR & FRANCIS INC, 2003)
The plasma-enhanced chemical vapor deposition of boron carbide was investigated on quartz glass and alumina substrates from a gas mixture of BCl3, H-2, and CH4 in an inductively coupled plasma (ICP) medium produced by a ...
Being well-informed about statin is associated with continuous adherence and reaching targets
(SPRINGER, 2005)
Background: Statins are life saving drugs in cardiovascular practice. However, they still are underprescribed in many situations despite their well-established benefits. Adherence may be improved by increased comprehension ...
