The resin of Ferula gumosa (galbanum) has been used in Persia for thousands of years. The habitats of this exceptional and endemic Iranian species is closely correlated to the parameters of rainfall and, mostly, to the usual winter fog. Within the last decades, the scarcity of the raw material was the reason for a dramatic increase in adulterations. Currently, more than five times the amount ac...

introduction: current study examined the possible role of the central nucleus of amygdala (cea) transient inactivation on the metabolic and hormonal disturbances induced by acute electro foot shock stress in female rats. considering the differences between female and male in responses to stress, this study attempts to reveal possible mechanisms underlying these differences. methods: uni- or bil...

the aim of this study was to report the endodontic management of right maxillary central incisor having two canals with vertucci canal configuration type iv . internal morphology of root canals is variable and often complex. therefore, to achieve a technically satisfactory endodontic outcome, the clinician must have adequate knowledge of the internal canal morphology and its variations in order...

introduction: giant cell lesions of the bone comprise a group of jaw bone pathologies. different pathogeneses such as reactive, vascular or neoplastic have been proposed for these lesions. in addition, differentiating between aggressive and nonaggressive central giant cell granuloma (cgcg) of the jaws based on histopathologic features is still impossible and due to different treatment protocols...

cell replacement therapy has provided the basis for future clinical applications to treat central nervous system injuries fallowing by car accidents. induced functional neurons are an option for replacing the lost neurons. the ability to monitor changes in membrane potential is a useful tool for studying neuronal function, but there are only limited options available at present. here, investiga...

background: central venous catheters (cvcs) have been used widely in clinics. these catheters are also recommended for children and infants receiving chemotherapy and total parenteral nutrition (tpn) and etc. in this paper, we present migrated fractured control line of the heart of a girl. case presentation: a 2.5 year old girl with migrated of the fractured central line into the heart. in the ...
