This study investigates the adsorption behavior of methyl orange (MO) by magnetic activated carbons (MACs) with different ratios AC: Magnetite from aqueous solution. Batch experiments for MO were carried out evaluating thermodynamics and kinetics parameters onto MAC adsorbents. Variables such as pH, initial concentration dye, contact time, temperature have been analyzed. The physicochemical cha...

Can the sorption mechanism be proven by fitting an isotherm model to experiment? Such a question arises because (i) multiple models, with different assumptions on mechanisms, often fit experimental equally well, (ii) some models [such as Brunauer–Emmett–Teller (BET) and Guggenheim–Anderson–de Boer (GAB)] isotherms that do not satisfy underlying of model, (iii) (such Oswin Peleg) are empirical e...

Glucocorticoids (GCs) immunosuppression acts via regulation of several transcription factors (TF), including activating protein (AP)-1, NF-kappaB, and NFAT. GCs inhibit Th1 cytokines and promote a shift toward Th2 differentiation. Th1 phenotype depends on TF T-bet. In this study, we examined GC regulation of T-bet. We found that GCs inhibit T-bet transcriptional activity. We show that glucocort...

adsorption of bovine serum albumin (bsa) onto calcium hydroxyl apatite (ha), ca10po4(oh)2, has been studied by ultra violet (uv) spectroscopy. the adsorption isotherms of bsa onto the ha surface at 291.7 k and 303.2 k were satisfactorily presented by langmuir equation and the evaluated parameters are reported. the specific surface area of ha has been measured by the bet method. the obtained val...

A T-box-containing protein expressed in T cells (T-bet) is a key transcription factor involved in the regulation of Th cell differentiation. Although T-bet-deficient CD4(+) T cells fail to produce IFN-γ and typically differentiate into Th2 cells in vitro, ectopic overexpression of T-bet elevates IFN-γ and suppresses production of IL-2 and Th2 cytokines through different mechanisms. Despite the ...

The past decade has seen an escalating enthusiasm to comprehend chronic tinnitus from the perspective of both scientific understanding and clinical management. At the same time, there is a significant interest and commercial investment in providing targeted and individualized approaches to care, which incorporate novel sound-based technologies, with standard audiological and psychological strat...

BACKGROUND Characterization of IgE-binding epitopes of allergens and determination of their patient-specific relevance is crucial for the diagnosis and treatment of allergy. OBJECTIVE We sought to assess the contribution of specific surface areas of the major birch pollen allergen Bet v 1.0101 to binding IgE of individual patients. METHODS Four distinct areas of Bet v 1 representing in tota...

The objective of this study is to experimentally determine the sorption isotherms and thermodynamic properties green mint after undergoing thermal biochemical treatment. method employed gravimetric using saturated saline solutions at various temperatures. In order model predict hygroscopic behavior during drying storage, we have utilized developed mathematical models (such as Langmuir, GAB, mod...

Pollution of water resources by various pollutants is nowadays a global environmental issue. Among the different type of water pollutants, dye represents a major polluting group. In this study, Azolla filiculides roots have been used for adsorption of Malachite Green (MG), a cationic dyed from aqueous solution. In this study, effects of operating parameters such as initial concentration of dye ...
