Sensitized NiO based photocathode is a new field of investigation with increasing scientific interest in relation with the development of tandem dye-sensitized solar cells (photovoltaic) and dye-sensitized photoelectrosynthetic cells (solar fuel). We demonstrate herein that PbS quantum dots (QDs) represent promising inorganic sensitizers for NiO-based quantum dot-sensitized solar cells (QDSSCs)...

Immunoglobulin E (IgE) has been shown to play a critical role in the allergic late-phase reaction, which is marked by intense leukocyte infiltration and edema. In this study we assessed the allergic pleural inflammation triggered by intrapleural (i.pl.) challenge in sensitized rats. We examined pleural effluent from actively sensitized rats following anti-IgE monoclonal antibody (mAb) (MARE-1) ...

In testing the hypothesis that interleukin-4 receptor alpha-subunit (IL-4R alpha)-coupled signaling mediates altered airway smooth muscle (ASM) responsiveness in the atopic sensitized state, isolated rabbit tracheal ASM segments were passively sensitized with immunoglobulin E (IgE) immune complexes, both in the absence and presence of an IL-4R alpha blocking antibody (anti-IL-4R alpha Ab). Rela...

INTRODUCTION Sensitization is associated with worse clinical outcomes after kidney transplantation (KT), including increased incidence of delayed graft function, acute rejection (AR) and graft loss. OBJECTIVES To evaluate 1-year efficacy and safety outcomes in sensitized KT recipients receiving antithymocyte globulin (ATG) induction and compare them to non-sensitized patients. METHODS Decea...

INTRODUCTION AND AIM The role of B-lymphocytes in chemical-induced asthma is largely unknown. Recent work demonstrated that transferring B lymphocytes from toluene diisocyanate (TDI)-sensitized mice into naïve mice, B cell KO mice and SCID mice, triggered an asthma-like response in these mice after a subsequent TDI-challenge. We applied two-dimensional difference gel electrophoresis (2D-DIGE) t...

OBJECTIVE The effects of natural adjuvants were examined on total and differential WBC counts in lung lavage of sensitized guinea pigs. MATERIALS AND METHODS In three sensitized groups of guinea pigs including: untreated sensitized animals (S), sensitized animals treated with adjuvant G2 (S+G2) and G2F (S+G2F) as well as non-sensitized group (C) (n=6 for each group), total and differential WB...

Respiratory syncytial virus (RSV) infection is considered a risk factor for bronchial asthma; however, the synergy between allergen sensitization and RSV infection in the development of pulmonary inflammation and asthma has been controversial. In this study the effects of primary and recurrent RSV infection on allergic asthma were examined in a group of control, RSV-infected, Dermatophagoides f...

Airway inflammation is the most characterized pathological feature in asthma. The antiinflammatory effect of the adjuvants is reported. Therefore, the effect of two different natural adjuvants on white blood cells (WBC) of lung lavage of sensitized guinea pigs were examined. White blood cells count and differential WBC of lung lavage were examined in control and 3 groups of guinea pigs includin...

BACKGROUND Exhaled nitric oxide (ENO) is elevated in bronchial asthma patients, and inhaled corticosteroid therapy lowers the elevated ENO levels in such patients. ENO appears to be an inflammatory marker, but its role in the pathophysiology of cough remains unclear. This study aimed to elucidate the relationship between NO and increased cough reflex sensitivity induced by allergic airway react...

Andrographis paniculata, "King of bitters" is a popularly known medicinal plant extensively used in many parts of the world for treatment of various diseases. Since recent past, anaphylactic/allergic type adverse events were reported upon A. paniculata usage, the study aimed to evaluate the anaphylactic and anaphylactoid potential of A. paniculata extract and andrographolide (a major phytoactiv...
