The alteration of two trioctahedral micas, biotite and phlogopite, was investigated at the meso, micro, nanoscale using three complementary microscopy techniques to better understand mica surface reactivity. In situ ex experiments were performed monitor mineral interface during dissolution in acidic solutions (nitric oxalic acid, pH ∼ 1–2), over a temperature range 25–100°C. inorganic acid used...

inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction. so the present study was designed to explore the acute effects of insulin on airway reactivity of guinea pigs and protective effects of salbutamol and beclomethasone against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pi...

Patients with hypertension in the clinic but not during daily activities ("white coat" hypertension) may be at lower risk of hypertensive morbidity and mortality than patients with hypertension in both settings ("persistent" hypertension). We hypothesized that the white coat phenomenon was due to greater blood pressure reactivity to the stress of a clinic visit and that, as a consequence, white...

background and objective: alzheimer’s disease (ad) is a multifactorial disease with debilitating consequences and few therapeutic strategies exist for it. with regard to antioxidant capacity and anti-β-amyloid polymerization potential of ellagic acid, this study was conducted to evaluate the effect of this substance on enhanced acetylcholinesterase reactivity in an experimental model of alzheim...

background and objectives: brucella melitensis infection is still a major health problem for human and cattle in developing countries and the middle east. materials and methods: in this study, in order to screen immunogenic candidate antigens for the development of a brucella subunit vaccine, a cytoplasmic protein (dnak) and an outer membrane protein (omp31) of b. melitensis were cloned, expres...

background: several studies reported the clinical features of ige-mediated hypersensitivity after ingestion of melon. melon allergy is a common ige-mediated fruit allergy in iran. this prompted us to investigate immunochemical and molecular properties of the major allergen in melon fruit, to compare the ige-binding capacity of the natural protein with the recombinant allergen, and to determine ...
