The pathogenesis of tobacco-related periodontal diseases is not well understood. The purpose of this study was therefore to investigate smokeless tobacco extract (ST) and nicotine effects on prostaglandin E2 (PGE2) and interleukin-1beta (IL-1beta) secretion by peripheral blood mononuclear cells (PBMC, consisting of monocytes and lymphocytes) and gingival(More)
Eighty-two periodontal patients were treated in a split mouth design with coronal scaling (CS), root planing (RP), modified Widman surgery (MW), and flap with osseous resection surgery (FO) which were randomly assigned to various quadrants in the dentition. Therapy was performed in 3 phases: non-surgical, surgical, and supportive periodontal treatment (SPT)(More)
Eighty-two periodontally involved patients were treated in a split mouth design such that one quadrant received coronal scaling (CS), root planing (RP), modified Widman surgery (MW), and flap with osseous resection surgery (FO). The therapy was performed in three phases: Phase I: the teeth previously designated to receive RP, MW, and FO were thoroughly root(More)
Eighty-two patients were treated in a split mouth design with coronal scaling (CS), root planing (RP), modified Widman surgery (MW), and flap with osseous surgery (FO) which were randomly assigned to the various quadrants in the dentition. Following phase I and phase II therapy, the patients received supportive periodontal treatment (SPT) at 3-month(More)
Previous investigations have dealt with significant alterations in pulpal respiration associated with dental materials and methods. The purpose of this investigation was to note if significant alterations in pulpal respiration remained after the insult had been removed. A rest period of 1 week was chosen to evaluate the pulpal respiration response after(More)
The Eastern Interconnection Phasor Projects (EIPP) is a Department of Energy (DOE) and Consortium for Electric Reliability Technology Solutions (CERTS) initiative to deliver immediate value of phasor technology to the Eastern Interconnection (EI) participants. With the current EI phasor network comprising of approximately 25 Phasor Measurement Units (PMU)(More)
In vitro tests in our laboratory have shown that 40% tetracycline HCl in a white petrolatum carrier (TTC-WP) has potential as a sustained release, autodissipating system. The present study tested subgingival placement of TTC-WP via syringe in vivo. Quadrants (2 diseased sites in each) in 9 patients with moderate/severe periodontitis were randomly assigned(More)
The purpose of this study was to compare, using cell blot analysis, the association of gingival tissue mononuclear cells (GTMC) isolated from lesions displaying histories of early-onset periodontitis (EOP; typically B-lymphocyte dominated) and gingivitis (typically T-lymphocyte dominated) with the B-cell stimulating cytokine, interleukin (IL)-4, and the(More)
Numerous membrane-bounded vacuoles are found adjacent to the plasma membrane of the pathogenic protozoan Giardia lamblia. The function of these vacuoles has been discussed by several authors. Approximately 100-400 nm in diameter with a core of low electron density, they have been suggested to be mitochondria, mucocysts, lysosomes, and endocytotic vacuoles.(More)
Resting cells of Bacteroides melaninogenicus fermented L-[14C]aspartate as a single substrate. The 14C-labeled products included succinate, acetate, CO2, oxaloacetate, formate, malate, glycine, alanine, and fumarate in the relative percentages 68, 15, 9.9, 2.7, 1.8, 1.0, 0.7, 0.5, and 0.06, respectively, based on the total counts per minute of the(More)
