BACKGROUND The goal of this prospective study was to estimate the absorbed (radiation) doses to salivary glands in radioiodine therapy of thyroid cancer under chewing-gum stimulation using (124)I positron emission tomography (PET)/computed tomography (CT) imaging. METHODS Duplex ultrasonography was conducted in three test persons for visual comparison of the glandular blood flow with three di...

Background Recently, the clinical use of low power lasers has increased, and it is said that wound healing is accelerated by their irradiation. The aim of this study was evaluation of the effect of platelet-rich plasma on proliferation and differentiation of human dental pulp stem cells with or without Ga-Al-As laser. Methods: In this experimental study, human lower third molar dental pulp c...

background and aims. the aim of present study was to investigate pulp-dentin complex reactions following direct pulp capping (dpc) with calcium hydroxide [ca(oh)2] and simvastatin as pulp-capping materials in the primary human molars. materials and methods. 120 primary molar teeth which had to be extracted for orthodontic reasons were randomly allocated into four groups. group ι as a control, u...

The aim of this study was to determine the effects of aromatherapy with sour lemon on nausea in patients undergoing chemotherapy. Methods: Fifty patients undergoing chemotherapy were assigned randomly to the experimental and placebo/control groups. The two groups was completed the Visual Analogue Sca...

background: stem cells from human exfoliated deciduous teeth (shed) have the capability to differentiate into neural cells. neurotrophins including nerve growth factor (ngf), brain-derived neurotrophic factor (bdnf), neurotrophin-3 (nt-3), and neurotrophin-4 (nt-4) have neurogenesis, neurotrophic, or neuroprotective effects and are expressed in developing teeth. the aim of this study was to mea...

The OntoLex W3C Community Group has been working for more than three years on a shared lexicon model for ontologies, called lemon. The lemon model consists of a core model that is complemented by a number of modules accounting for specific aspects in the modeling of lexical information within ontologies. In many usage scenarios, the discovery and exploitation of linguistically grounded ontologi...
