Periodontal disease is an inflammatory disease process, resulting from the interaction of a bacterial attack and host inflammatory response. Arrays of molecules are considered to mediate the inflammatory response including free radicals and reactive oxygen species (ROS). Periodontal pathogens can induce ROS overproduction and thus may cause collagen and periodontal cell breakdown. When ROS are ...

Correlations between magnetic reconnection and energetic ion flow events have been measured with merging force free spheromaks at the Swarthmore Spheromak Experiment. The reconnection layer is measured with a linear probe array and ion flow is directly measured with a retarding grid energy analyzer. Flow has been measured both in the plane of the reconnection layer and out of the plane. The mos...

OBJECTIVES To evaluate the effect of hyperbaric oxygen therapy (HBO2) as an adjunct to scaling and root planing (SRP) in the treatment of severe cases of chronic periodontitis. MATERIALS AND METHODS In 20 patients diagnosed with severe generalized chronic periodontitis (pockets>7mm) with bleeding on probing, SRP was rendered in all pockets. Additionally, five consecutive hyperbaric sessions w...

This paper aims at studying the effect of the dynamic errors on surface measurements using three different types of touch trigger probes attached to a bridge-type-CMM. Unforeseeable dynamic root errors of a ductile touch trigger probing system have been characterized theoretically and experimentally as well. The results were employed in validating a developed analytical twodimensional-model (2D...

A modern technology in the area of intrusion detection is honeypot technology that unlike common IDSs tends to provide the attacker with all the necessary resources needed for a successful attack. Honeypots provide a platform for studying the methods and tools used by the intruders (blackhatcommunity), thus deriving their value from the unauthorized use of their resources. This paper discusses ...

background and aims. the aim of this study was to compare the effectiveness of adjunctive photodynamic therapy (pdt) in the treatment of aggressive periodontitis. materials and methods. a total of 24 patients with clinical diagnosis of aggressive periodontitis received scaling and root planing (srp) for periodontal treatment. in a split-mouth design study, the teeth of one quadrant of each arch...

objectives: falling in the elderly is common and dynamic balance has direct effect abstract  on it. therefore, we decided to study the effect of functional training on dynamic balance in healthy elderly women. methods & materials: thirty healthy elderly women were purposefully selected as subjects and then randomly divided into two equal groups (control and experimental groups). the dynamic bal...

Dynamic Web data sources – sometimes known collectively as the Deep Web – increase the utility of the Web by providing intuitive access to data repositories anywhere that Web access is available. Deep Web services provide access to real-time information, like entertainment event listings, or present a Web interface to large databases or other data repositories. Recent studies suggest that the s...
