scaffold design has pivotal role in tissue engineering. in the present study, we modified the surface of electrospun poly(caprolactone) (pcl) nanofibers to improve their compatibility with living medium and to show the potential application of pcl nanofibers as a artificial extracellular matrix using in tissue-engineering. pcl nanofibers were fabricated by electrospinning method. to graft gelat...

background: e-cadherin is a calcium-dependent molecule that contributes to intercellular adhesion. its proper functioning is important in the maintenance of epithelial structure and integrity. e-cadherin serves as a very important tumor suppressor. in this study, we aimâ to determineâ the frequencyâ of e-cadherin expression aberrancy and its relationship to theâ biologicalâ behavior of gastric ...

ameloblastomas are regarded as a homogeneous group of neoplasms with locally invasive character. they generally do not show induction of dental hard tissue formation except in few cases. biological behavior and histogenesis of these tumors is still unexplored as there is lack of relevant studies and long follow-up of these patients. so, we aimed to report this rare case of dentinoameloblastoma ...

objective: antisocial, aggressive and delinquent behaviors in adults often begin early in life. basal cortisol is a valuable biological marker in children with disruptive behavior disorder (dbd). to investigate the association between biological factor (cortisol) and disruptive behaviors, we studied the effect of family training on salivary cortisol level in children with dbd. methods: basal sa...
