Background and objective:Gingival bleeding reduction in smokers has been associated with decreased blood vessel density. The mechanism of suppressive effect of cigarette smoking on blood vessel density is not precisely defined. The aim of this study was to evaluate the impact of smoking on angiogenesis by assessing mast cells density and VEGF expression in chronic peri...
abstract background numerous disorders can cause recurrent abdominal pain. many of these cases underwent endoscopy and clinician encounters patients with history of recurrent abdominal pain and normal endoscopy. we evaluated these biopsies with regard to their eosinophils and mast cell densities to find out a potential relationship between recurrent abdominal pain with eosinophils and mast cell...
This study aims to characterize and evaluate the applicability of Polyhedral OligomericSilsesquioxane (POSS)/ Poly (carbonate-urea) Urethane (PCU) nanocomposite films as a temporary skin substitute by means of FTIR, MTT assay, cell proliferation assay and SEM studies. FTIR spectra showed all the characteristic peaks of POSS/PCU nanocomposite. The indirect cytotoxicity of membranes was investig...
Background and purpose: The 50 KDa protein (50 µg) in carboxylic domain of the neurotoxin heavy chain (BoNT/A-Hc) recognizes surface receptors on target neurons and this fragment contains the principle protective antigenic determinants. Recently, this fragment has been used as a recombinant vaccine candidate for botulism. The study aimed to compare the evaluation of BoNT/A-Hc production in fed-...
Background and Objective: The role of mast cells in carcinogenesis is improved in many malignant neoplasms but there are scanty literature which show the role of these cells in pathogenesis of progression of dysplastic lesion to invasive squamous cell carcinoma (SCC). The aim of this study was comparison of mast cell density between squamous cell carcinoma and dysplastic laryngeal mucosa to inv...
In this paper, Plug-in Fuel Cell Electric Vehicle (PFCEV) is considered with dual power sources including Fuel Cell (FC) and battery Energy Storage. In order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. In order to simulate the...
abstract background and aims. reliable immunohistochemical assays to evaluate the definitive role of mast cells and angiogenesis in the pathogenesis of oral reactive lesions are generally not available. the purpose of the present study was to compare mast cell count (mcc) and microvessel density (mvd) between oral reactive lesions and evaluation of the correlation between mcc and mvd in these l...
The aim of this study was to investigate the effect of different light intensities and ascorbic acid on some physiological and biochemical characteristics of Zinnia elegans L. The experiment was designed as a completely randomized design in a form of split-plot with three replications. The treatments were consisted of three light intensity levels (600, 1200 and 1800 μmol m-2 s-1) as the main fa...
