introduction: today nano-medicine tries to produce new drugs to reduce the dosage and side effects of their conventional forms. according to the interaction between zinc and opioidergic system activity, this study has investigated the effect of new kind of zinc supplement, nano zinc oxide (nzno), in compared to its conventional form (czno), in presence and absence of opioidergic system activity...

introduction: in open reduction and internal fixation for the treatment of mandibular fracture, the fixation technique used is very important in reducing post-operative complications and promoting the healing process. this study assessed the results of fixation of the mandible using two mini-plates perpendicular to each other in the lower border of the mandible for fracture treatment.    materi...

introduction: in order to assess our skill in the tubularized incised plate (tip) urethroplasty technique in children with hypospadias. material andmethods: of 307 children (mean age 38 month) who received a tip urethroplasty, all had primary hypospadias. patients who were referred with complication were eliminated from our study. the hypospadias defects were subcoronal in 25 (8%), distal penil...

the objective of the present study is the synthesis of mwcnt-tio2 hybrid nanostructures by solvothermal synthesis method with ticl4 as precursor. the heat transfer enhancement due to the use of mwcnt-tio2 nanofluid was investigated. as-prepared hybrid materials were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). the results showed that mwcnts were uniformly dec...

mass vaccination against viral infections such as mumps is a very noticeable and appropriate attempt in common health. mumps infection has severe complications like deafness, infertility and meningitis. attenuated live vaccine of mumps is produced and used to prevent the problems. viral content in the monovalent vaccine is assayed with different methods. nowadays international standards introdu...

objective(s) studies have shown that morphine, in addition to its analgesic properties, has several effects on cell proliferation and apoptosis. there is also evidence that opioid receptors are present on chondrocytes. our main objective in the present study was to investigate the effects of morphine on rat femur growth cartilage. materials and methods this research was carried out on 18 4-week...

License plate recognition (LPR) has many applications in traffic monitoring systems. In this paper, a vertical edge matching based algorithm to recognize Korean license plate from input gray-scale image is proposed. The algorithm is able to recognize license plates in normal shape, as well as plates that are out of shape due to the angle of view. The proposed algorithm is fast enough, the recog...

The equal division of chromosomes among daughter cells at mitosis involves a complex series of kinetochore-dependent chromosome movements. The kinetochore-associated CENP-E motor protein is critical for the sustained movement of chromosomes towards the metaphase plate during chromosome congression.
