objective(s):bone marrow-derived mesenchymal stem cells (bmscs) have attracted significant interest to treat asthma and its complication. in this study, the effects of bmscs on lung pathology and inflammation in an ovalbumin-induced asthma model in mouse were examined. materials and methods:balb/c mice were divided into three groups: control group (animals were not sensitized), asthma group (an...

the dye-sensitized solar cells (dssc) have been regarded as one of the most promising new generation solar cells. tremendous research efforts have been invested to improve the efficiency of solar energy conversion which is generally determined by the light harvesting efficiency, electron injection efficiency and undesirable electron lifetime. in this review, various characteristics of dye-sensi...

This study aimed to present a mouse model of ovalbumin (OVA) induced allergic diarrhea under a sub-barrier system and investigate the development of gut microbiota in this model. Male BALB/c mice were systemically sensitized with OVA or sham-sensitized with saline, and followed by oral OVA intubation, leading to OVA-specific acute diarrhea. Compared with sham-sensitized mice, sera OVA-specific ...

Allograft rejection in sensitized recipients remains the major problem in clinical organ transplantation. We have developed a donor-type skin-sensitized mouse cardiac allograft model (BALB/c-->C57BL/6) in which both rejection (<5 days) and alloreactive CD8 activation are resistant to CD154 blockade. First, we attempted to elucidate why CD154 blockade fails to protect cardiac grafts in sensitize...

1. Rabbits were immunized with Bact. typhosum 0 901 S and 0 901 R, over a long period. Homologous and heterologous strains were sensitized with sera obtained from weekly bleedings. Agglutination titer was recorded, and the isoelectric points of the bacteria maximally sensitized were determined. 2. 0 901 S maximally sensitized with homologous immune serum had isoelectric points which became more...

BACKGROUND Airway challenge of ovalbumin-sensitized mice induces intrapulmonary accumulation of eosinophil progenitors. OBJECTIVE To evaluate whether allergen-challenged lungs release factors promoting intrapulmonary accumulation of haemopoietic cells, and define the role of allergic lung injury, we developed a transplantation model. METHODS Lung tissue from allergen-challenged, sensitized ...

Asthma is a global problem that affects over 300 million people in the world. The main reason of asthma is allergy and atopy. Asthmatic patients are sensitized to allergens that can be resulting asthma attacks. Fungi as an allergen can be sensitized atopic people and present a severe asthma. Fungi have been found in water-damaged homes of asthmatic patients. Allergic asthma is associated with e...

objective(s):with regard to pharmacological effects of carvacrol on the respiratory system, its effect on cytokines genes expression in splenocytes of asthmatic mice was examined in this study. materials and methods:splenocytes were isolated from non-sensitized (control group), sensitized mice to ovalbumin (ova) (group s), and s animals treated with dexamethasone, and three concentrations of ca...

a simple and sensitive chemiluminescence-based method was established for the determination of rabeprazole.the proposed method was based on the enhancing effect of rabeprazole on ce(iv)-na2so3 -tb(iii) chemiluminescence reaction. a possible mechanism was discussed for chemiluminescence system by studying uv-vis, fluorescence and chemiluminescence spectra. the effects of various chemical paramet...

in this study, we investigated the effect of using large tio2 nanoparticles in the matrix of small nanoparticles to improve the performance of dye-sensitized solar cells (dsscs), as light scatter to increase the light harvesting. the mixed powder was deposited by electrophoretic deposition (epd) on fto (f-sno2 coated glass). it is shown that adding small quantity of larger nanoparticles can enh...
