The influence of magnesium on the activity of some enzymes (AST, ALT, ALP) and lead content in some tissues
(John Libbey Eurotext Ltd, Montrouge, 2002)
Many authors in different studies have reported the antagonism between Mg and Pb. Our previous results suggested that oral Mg treatment have better effect on investigation biochemical parameters (protoporphyrins, aminolevulinic ...
Morphological evaluation of 2-and 1-step self-etching system interfaces with dentin
(Operative Dentistry Inc, Indianapolis, 2006)
This in vitro study evaluated the resin-dentin interface formed by two 2-step and two 1-step self-etching adhesive systems under SEM. Class V cavities (4 x 2.5 x 1.5 mm) were prepared on the buccal surfaces of 25 extracted ...
A biased Gm haplotype and Gm paraprotein allotype in multiple myeloma suggests a role for the Gm system in myeloma development
(Wiley, Hoboken, 2007)
The association between a particular Gm haplotype and susceptibility to multiple myeloma (MM) is not clear. The reason is probably because no investigations have so far been carried out on the relationship between the Gm ...
Effect of curing modes of dual-curing luting systems and root regions on retention of translucent fiber posts in root canals
(Journal of Adhesive Dentistry, 2008)
Purpose: To evaluate the effect of different curing modes of dual-curing luting systems and root regions on the pushout strength of fiber posts to intraradicular dentin. Materials and Methods: Forty-two extracted premolars ...
Maxillary sinus floor augmentation: comparing osteotome with lateral window immediate and delayed implant placements. An interim report
(Mosby-Elsevier, New York, 2008)
Objective. A retrospective study was performed to observe clinical outcomes of dental implants placed in augmented maxillary sinuses using an osteotome or a lateral approach technique with synchronous or delayed implant ...
The role of central vasopressin receptors in the modulation of autonomic cardiovascular controls: a spectral analysis study
(Amer Physiological Soc, Bethesda, 2006)
Although it has been suggested that vasopressin (VP) acts within the central nervous system to modulate autonomic cardiovascular controls, the mechanisms involved are not understood. Using nonpeptide, selective V-1a, V-1b, ...
Effect of intermediate agents and pre-heating of repairing resin on composite-repair bonds
(Operative Dentistry Inc, Indianapolis, 2007)
This study investigated the composite-to-composite microtensile bond strength and interfacial quality after using different combinations of intermediate agents and pre-curing temperatures of repairing resin. Forty-five ...
A study of temperature rise in the pulp chamber during composite polymerization with different light-curing units
(Jaypee Brothers Medical Publishers (P) Ltd, 2007)
Aim: The study compared pulp temperature rise during polymerization of resin-based composites (RBCs) using halogen and LED light-curing units (LCUs). Methods and Materials: A total of 32 teeth extracted from patients aged ...
Fracture resistance of fiber posts: Combinations of several small posts vs. standardized single post
(American Journal of Dentistry, 2008)
Purpose: To determine the fracture resistance of different sizes of standardized single fiber posts and the combinations of multiple small experimental posts. Methods: Single posts in three different sizes (l, 2 and 3; DT ...
Calcium and magnesium content in hard tissues of rats under condition of subchronic lead intoxication
(Magnesium Research, 2008)
Lead manifests toxic effects in almost all organs and tissues, especially in: the nervous system, hematopoietic system, kidney and liver. This metal has a special affinity for deposition in hard tissue, i.e., bones and ...
