اسانس گیاهان (خشک شده در سایه)، tanacetum tenuisectum , tanacetum polycephalum به دو روش: 1- تقطیر با آب 2- برای اولین بار به روش میکرواستخراج فاز جامد در فضای فوقانی گرفته شد و به روش gc/ms مورد آنالیز و شناسایی واقع گردید. عمده ترکیبات اسانس سرشاخه های گلدار گیاه (tanacetum polycephalum) hydrodistillation % compounds 12.07 camphor 10.66 1, 8- cineole 9.57 chrysanthenyl acetate – t...
کمپلکس های مسطح مربعی پلاتین(ii) در حضور لیگاندهای دی ایمینی ساخته شدند. واکنش k2ptcl4با 7،4- فنانترولین منجر به تشکیل [ptcl2(4,7-phen)] شد که احتمالا? به صورت پلیمری می باشد. کمپلکس [ptcl(4,7-phen)(sme2)] از واکنش [ptcl2(sme2)2] با 7،4- فنانترولین سنتز شد. جداسازی جامد حاصل از این واکنش به وسیله اتر منجر به تولید فرم پلیمر [ptcl(4,7-phen)(sme2)] شد، در حالی که در حضور اتر و دی کلرومتان فرم مون...
Objective: The aim of this study was to investigate the effectiveness of therapy based on trans-theoretical model (TTM) in coping strategies among male substance dependent patients under methadone maintenance therapy in Najaf Abad city. Method: To this end, a quasi-experimental research design along with control group was employed the relevant evaluation was performed in pre-test, post-test, an...
In this paper, on the basis of tight-binding model and a generalized Green- function method as well as Lanczos algorithm procedure, the effects of the metal-molecule coupling(MMC) strength on the electronic transmission through a metal-single molecule-metal(MMM) system is investigated. Using the Landauer formalism we study some of the significant conductance properties of this system as a mol...

Stilbenoids are natural compounds endowed with several biological activities, including cardioprotection and cancer prevention. Among them, (±)-trans-δ-viniferin, deriving from trans-resveratrol dimerization, was investigated in its ability to target DNA duplex G-quadruplex structures by exploiting NMR spectroscopy, circular dichroism, fluorescence spectroscopy molecular docking. (±)-trans-δ-Vi...
carpal fracture-dislocation is regarded as an unusual orthopedic injury and, thus, orthopedic surgeons are less experienced in dealing with and treating these fractures and dislocations. we report a 20-year-old worker man suffering from an unusual carpal fracture-dislocation. there was trans-scaphoid fracture and lunate dislocation with other carpal proximal bones toward volar of the wrist. two...
background and objectives: low fruit/vegetable (fv) diet seems to be a global public health problem. the trans-theoretical stages of change model have long been considered a useful interventional approach in lifestyle modification programs. the aim of this study was to find the most important intermediating factors of fv consumption in mashhad, iran. materials and methods: in this cross-section...
cushing’s syndrome which is an uncommon but lethal disorder occurs due to many causes. the most common endogenous cause is cushing’s disease or pituitary cushing. the etiology of this disorder is an adenoma in the anterior pituitary. the most important point in the treatment of this disorder is differentiation between cushing’s disease (pituitary) and cushing’s syndrome (adrenal). we can differ...
the composition of essential oil of leaves of the male and female shrubs of juniperus chinensis l. (growing in isfahan) was analyzed by gas choromatography(gc) and gc-mass spectrometery (ms). the main constituents of leaf oil of the male shrub were: bornyl acetate (26.1%), sabinene (18.3%), trans-sabinyl acetate (11.1%), myrcene (9.2%), limonene (6.1%), elemol (5.5%), α-cadinol (2.3%), δ-cadine...
