the stimulatory effect of the extract of portulaca oleracea (p. olerace) on β-adrenoceptor of tracheal smooth muscle was examined. to examine β-adrenoceptor stimulatory effect, concentration response curve to isoprenaline was obtained in pre-contracted tracheal smooth muscle in the presence of three concentrations of aqueous-ethanolic extract, propranolol and saline. values of ec50 (the effecti...
beryllium oxide (beo) nanopowder was synthesized using sol-gel method and the effects of changes of chemical reagents were investigated. because of tissue equivalence and other outstanding thermoluminescence (tl) properties of the bulk material in x and γ dosimetry, the applicability of this nanostructure in tl dosimetry was studied following irradiation to the 137 c...

abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
Context. Population studies of the distribution of T4/TSH set points suggest a more complex inverse relationship between T4 and TSH than that suggested by physiological studies. The reasons for the similarities and differences between the curves describing these relationships are unresolved. Methods. We subjected the curve, derived from empiric data, describing the TSH suppression response to T...

In this study, the pure nano-structure hydroxyl apatite samples were synthesized via hydrolysis method. The powder samples were sintered at various temperatures of 500°C, 700°C and 900°C in a furnace. X-ray diffraction (XRD) and Fourier transform infra-red (FTIR) spectroscopy systems were used to characterize the synthsized samples. Comparison of the glow curves shows that the most ...
Frankenia hirsuta is a perennial halophyte species playing an important role in forage production in Incheboron, Golestan Province. Examining the ecological niche of this species in rangeland ecosystems of Incheboron can predict their response to environmental factors and the effective management. The objective of this study was to investigate the response of Frankenia hirsuta species to some e...
