Allergic airway diseases are related to exposure to atmospheric pollutants, which have been suggested to be one factor in the increasing prevalence of asthma. Little is known about the effect of ozone and diesel exhaust particulates (DEP) on the development or aggravation of asthma. We have used a mouse asthma model to determine the effect of ozone and DEP on airway hyperresponsiveness and infl...

The past few years have been great for semiconductor quantum dot-sensitized solar cells (QDSSCs). For the first time, efficiency exceeding 15% has reported. This narrowed gap with other emerging cell technologies such as dye-sensitized and thin film cells. In this miniperspective, reason improvement is briefly reviewed. Few advancements identified that are responsible performance breakthrough i...

BACKGROUND Late asthmatic response is observed following antigen challenge in actively, but not passively, sensitized guinea pigs. Although cough reflex sensitivity is increased after antigen challenge in actively sensitized guinea pigs, it is unknown whether the antigen-induced increase in cough reflex sensitivity develops in passively sensitized animals. The aim of this study was to compare t...

background: cuminum cyminum fruit essential oil (feo) dose-dependently can attenuate the expression of morphine tolerance and dependence in morphine-dependent mice. objective: in this study, the effects of cuminum cyminum feo on acquisition and expression of morphine-induced conditioned place preference (cpp) in morphine-sensitized mice were studied. methods: repeated subcutaneous (s.c.) admini...

INTRODUCTION In transfusion medicine, antibodies that cause RBCs positive DATs, may interfere with patients' phenotyping. Traditionally, these antibodies were removed using various antibody elution methodologies. However, the elution agents and conditions used have been only partially successful; and no one method is superior. The purpose of this study was to develop a general and efficient met...

cow’s milk allergy is one of the most common food allergies in childhood. beta- lactoglobulin (β-  lg) is  a dominant  allergen in  cow’s milk. hydrolysis is  known as  an effective method to reduce the allergenicity of proteins. thus, the objective of this study was to compare the allergenicity of β-lg and its hydrolysates using an animal model. twenty four balb/c mice were divided into three ...

effects of intra-central amygdala administration of l-arginine, a nitric oxide precursor, and ng-nitro-l-arginine methyl-ester (l name), a nitric oxide synthase inhibitor, on the morphine-induced sensitization and also on the expression of morphine-induced place conditioning in rats were studied. subcutaneous (s.c.) administration of morphine (2.5, 5 and 7.5 mg/kg) induced place conditioning. r...

OBJECTIVE Humoral immunity has been clearly implicated in solid organ transplantation, but little is known about the relationship between humoral immunity and hematopoietic stem cell transplantation. This study was designed to investigate that relationship. MATERIALS AND METHODS Sensitized serum was obtained from a sensitized murine model established by allogeneic splenocyte transfusion. Sens...

This study explored the effects of microRNA-19b (miR-19b) on airway remodeling, airway inflammation, and degree of oxidative stress in a mouse model of asthma. Bioinformatics analyses and dual luciferase reporter gene assays revealed that thymic stromal lymphopoietin (TSLP) is a direct target of miR-19b. An asthma model was established via ovalbumin (OVA) sensitization and challenge in 72 femal...

The effects of Ocimum basilicum (O. basilicum) and its constituent, rosmarinic acid, on total and differential blood WBC, serum levels of NO2, NO3, MDA, thiol, SOD and CAT in sensitized rats were examined. The study was performed in control animals (group C) and eight groups of sensitized rats to ovalbumin which were given drinking water alone (group S), drinking water containing three concentr...
