introduction: the aim of this study was to evaluate the root canal morphology of mandibular first and second molars using cone-beam computed tomography (cbct) in northern iranian population and also to indicate the thinnest area around root canals. methods and materials: we evaluated cbct images of 154 first molars and 147 second molars. by evaluating three axial, sagittal and coronal planes of...

Design, fabrication and tests of a monolithic compliant-flexure-based microgripper were performed. The geometry design and the material tresses were considered through the finite element analysis. The simulation model was used to study in detail profiles of von Mises stresses nd deformation. The maximum stress in the microgripper is much smaller than the critical stress values for fatigue. The ...

background: candida species are among the most common causes of opportunistic fungal diseases. among candida species, candida albicans is responsible for most infections. having many strains, c. albicans is very polymorph. c. dubliniensis is very similar to albicans species both morphologically and physiologically. for an infection to occur, cell wall proteins play an important role as they ena...

In this study, blueberry essential oil as a core material was microencapsulated with Inulin and β-cyclodextrin at a ratio of 1:5 (core: wall). Oil in water nano-emulsions were prepared by ultrasonic liquid processors and then transformed to encapsulate powder in spray dryer. Dried powder was stored at 4 ˚C in refrigerator for determining moisture, encapsulation efficiency and morphology prop...

To investigate whether cell wall mannan from Candida metapsilosis induces vasculitis similar to that in Kawasaki syndrome and anaphylactoid shock in mice, we examined the pathogenic effects of C. metapsilosis cell wall extracts. Our results show that intraperitoneal injection of cell wall extracts induced severe coronary arteritis, and intravenous injection induced acute anaphylactoid shock sim...

background: cryptosporidium species are important cause of diarrheal diseases in both developing and developed countries. this study aimed to compare the perfor-mance of several molecular methods for identification of cryptosporidium species, and to detect genetic variation among each of these species isolated from iran, ma-lawi, nigeria, vietnam and the united kingdom. methods: the oocysts dna...
