Effect of carvacrol on tracheal responsiveness, inflammatory mediators, total and differential WBC count in blood of sensitized guinea pigs.

The effects of carvacrol on tracheal responsiveness (TR) to methacholine and ovalbumin (OA), serum nitric oxide (NO) concentration, total and differential white blood cells (WBC) in blood of sensitized guinea pigs were examined. Five groups of guinea pigs sensitized to OA were given drinking water alone (group S), drinking water containing three concentrations of carvacrol (40, 80 and 160 µg/mL) and dexamethasone (50 µg/mL). TR to methacholine and OA, serum NO concentration, total and differential WBC in blood of sensitized and control guinea pigs were measured (n = 6, for each group).

In vivo and in vitro anti-angiogenesis effect of venom-derived peptides (ICD-85).

Exercise induced bronchospasm in physically fit female students of Kerman University and their pulmonary function tests.

Introduction: High prevalence of respiratory symptoms and bronchial hyper-responsiveness has been reported in professionals athletes, particularly in relation to climate and environment. However, the airway response to exercise in active population has been poorly investigated especially in women. The aim of this study was to examine pulmonary function test changes in physically fit female students of Kerman University.

An electrical circuit model for simulation of indoor radon concentration.

In this study, a new model based on electric circuit theory was introduced to simulate the behaviour of indoor radon concentration. In this model, a voltage source simulates radon generation in walls, conductivity simulates migration through walls and voltage across a capacitor simulates radon concentration in a room. This simulation considers migration of radon through walls by diffusion mechanism in one-dimensional geometry.

The prevalence of common CFTR mutations in Iranian infertile men with non-CAVD obstructive azoospermia by using ARMS PCR techniques.

Purpose: To evaluate five common cystic fibrosis trans-membrane conductance regulator (CFTR) mutations (ΔF508, G542X, R117H, W1282X and N1303K) in the Iranian infertile men with noncongenital absence of vas deferens (CAVD) obstructive azoospermia.

Methods: The common CFTR gene mutations were tested on blood samples from 53 infertile men with non-CAVD obstructive azoospermia and 50 normal men as control individuals. Genomic DNA is extracted from the whole blood and the common CFTR mutations have been detected by the amplification refractory mutation system (ARMS) techniques.

Gene Expression Quantification of Toll like Receptors 2, 4 and Co-molecules in Human Glioblastoma Cell Line (U87-MG): Toward a New In vitro Model of Inflammation.

Objectives: Pattern recognition receptors (PRRs) are the main part in the innate immune response. Human glioblastoma cell line (U87-MG) is an established adherent cell line model of this common cancer; due to genetic variations between individuals it is likely more suitable for investigating molecular aspects of innate immunity. Therefore, we undertook a novel characterization of the immune phenotype of U87-MG toward establishing a base for future researches.

Immunomodulatory properties of borage (Echium amoenum) on BALB/c mice infected with Leishmania major.

Leishmaniasis is caused by parasitic protozoa transmitted by the bite of a female sand fly and is currently endemic in 88 countries. BALB/c mice are highly susceptible to the infection with the parasite Leishmania major, and this susceptibility has been attributed, in part, to the expansion of Th2 cells, production of their cytokines, and downregulation of Th1 cytokine, interferon gamma (IFN-γ). In this report, we used both aqueous and alcoholic extracts of Iranian borage (Echium amoenum Fisch & C.

Iranian study highlights youngsters' preferences.

According to Professor Sanaz Litkouhi, Ph.D, an assistant professor of architecture at the Payam-Noor University of Tehran, the general lack of emphasis on providing suitable activity facilities in children's hospitals affects both recovering child patients' state of mind and the overall healing process. This paper describes a recent questionnaire-based study which gauged the views of adolescents and younger children on the current shortcomings and space issues in children's hospitals in Iran, with the responses then used to develop future design and planning guidelines.
