The role of nickel accumulation and epithelial cell proliferation in orthodontic treatment-induced gingival overgrowth
(OXFORD UNIV PRESS, 2007)
The aim of this study was to investigate the role of nickel in orthodontic treatment-induced gingival hyperplasia. The nickel concentration in gingival tissues with and without overgrowth, histopathology of gingival ...
Aromatase expression in uterine leiomyomata is regulated primarily by proximal promoters I.3/II
(ENDOCRINE SOC, 2007)
Context: Uterine leiomyomata are common tumors that cause irregular uterine bleeding and pregnancy loss and depend on estrogen for growth. Aromatase catalyzes the conversion of androgens to estrogens. Aromatase expression ...
Structure-property relation of a soft liner material used in denture applications
(JAPANESE SOC DENTAL MATERIALS DEVICES, 2007)
With a view to understanding the structure-property relation of a silicone-based soft lining denture material after polymerization, its chemical composition and viscoelastic properties were investigated. Chemical compositions ...
Microhardness evaluation of resin composites polymerized by three different light sources
(JAPANESE SOC DENTAL MATERIALS DEVICES, 2007)
This study examined the surface microhardness of four kinds of resin composites with different fillers and resin matrices. Ten specimens of 2 mm thickness and 4 mm diameter of each resin composite were polymerized using a ...
Mesial migration effect on root morphology of mandibular third molars
(E H ANGLE EDUCATION RESEARCH FOUNDATION, INC, 2007)
Objective: To test the hypothesis that there is a relationship between forward mandibular third molar migration and root curvature of the mandibular third molars. Materials and Methods: The study is comprised of 64 patients ...
Effect of thermocycling on tensile strength and tear resistance of four soft denture liners
(JAPANESE SOC DENTAL MATERIALS DEVICES, 2007)
This study evaluated the effect of thermocycling on the tensile strength and tear resistance of four long-term soft denture liners. One light-activated (Astron Light, AL), two chemically activated (GC Reline Soft, GC; ...
Thorax deformity, joint hypermobility, and anxiety disorders
(SAUDI MED J, 2007)
Objective: To evaluate the association between thorax deformities, panic disorder, and joint hypermobility. Method:The study includes 52 males diagnosed with thorax deformity, and 40 healthy male controls without thorax ...
Intuitionistic fuzzy sets in gamma-semigroups
(KOREAN MATHEMATICAL SOC, 2007)
The notion of a fuzzy set in a set was introduced by L. A. Zadeh [10], and since then this concept has been applied to various algebraic structures. K. T. Atanassov [1] defined the notion of an intuitionistic fuzzy set, ...
Experimental techniques for investigating the surface oxygen formation in the N2O decomposition on Fe-MFI zeolites
(ELSEVIER SCIENCE SA, 2007)
Several experimental techniques were used to investigate the formation of surface oxygen in the N2O decomposition on an Fe-MFI zeolite. These techniques consisted of multipulse and step experiments as transient methods at ...
Effect of exchange-correlation potential on the plasmon dispersions in a doped symmetrical double quantum well
(WILEY-V C H VERLAG GMBH, 2007)
We have calculated the plasmon dispersion relations in a doped double quantum well with and without exchange-correlation potential added to the effective potential of the system. The calculations were done for high and low ...
