o bjectives: this study sought to assess distal and lateral forces and moments of asymmetric headgears by variable outer bow lengths. materials and methods : four 3d finite element method (fem) models of a cer- vical headgear attached to the maxillary first molars were designed in solidworks2010 software and transferred to ansys workbench ver. 11 software. modelscontained the first molars, thei...

in this study ten pairs of superior gland of third eyelid of 10 adult male camels free of apparent ocular disease were examined to compare the normal anatomical and histological properties of these glands. after dissecting, all of the glands were characterized and measured (length and width) on both the left and right side. in the camels, the superior gland of the third eyelid was oval shaped a...

objectives: this study aimed to evaluate the location and characteristics of mental foramen, anterior loop and mandibular incisive canal using cone beam computed tomography (cbct). materials and methods: this retrospective cross-sectional study evaluated 200 mandibular cbct scans for the location of mental foramen, anterior loop prevalence and mandibular incisive canal visibility, its mean leng...

root-knot nematodes are one of the limiting factors in seedling production and new olive gardens establishment in iran. in view of find resistance cultivars to root-knot nematodes, importance of careful identification of species and races are clarified. in order to investigate root-knot nematodes on olive, soil and root samples of gardens and nursery in gorgan area were collected. in this study...

The jugular foramen (JF) varies in shape and size from side to side in the same cranium, and in different crania, racial groups and sexes. Side dominance is also said to be common. The foramen's irregular shape, its formation by two bones and the numerous nerves and venous channels that pass through it further compound its anatomy. A morphometric study of 20 (40 JF) adult male Nigerian dry skul...

polyvinylidene fluoride/polyvinylpyrrolidone (pvdf/pvp) hollow fiber membranes were fabricated by dry-jet wet-spinning process. the correlated effects of the air gap length and pvp concentration ((1) the air gap length effect at the low and high pvp concentration in the dope solutions, as well as (2) the effect of the pvp concentration at the same air gap length) on the cross-section structure ...

BACKGROUND Cytoplasmic dynein mediates spindle positioning in budding yeast by powering sliding of microtubules along the cell cortex. Although previous studies have demonstrated cortical and plus-end targeting of dynein heavy chain (Dyn1/HC), the regulation of its recruitment to these sites remains elusive. RESULTS Here we show that separate domains of Dyn1/HC confer differential localizatio...

Introduction: Correct interpretation of kidney images requires the knowledge of its normal size. This study aimed to establish normal values for kidney length and parenchymal thickness and identify the potential related factors in a group of Iranian adults. Methods: Renal dimensions, including length and parenchymal thickness were measured by sonography in 103 individuals with n...

Background & Aim: DBS (deep brain stimulation) is a new and successful technique in treatment of symptoms of Parkinsonism especially after drug resistance. Research in this field is mostly designed for evolution of this technique. The present study aimed at evaluating the relationship between the angle formed in midsagittal and STN (sub-thalamic nucleus) axis line and recording l...
