Cylindrical specimens of bone measuring 15 mm in diameter were obtained from the lateral cortical layer of 10 pairs of femurs and tibias. A central hole 3.2 mm in diameter was drilled in each specimen. The hole was tapped, and a 4.5 mm cortical bone screw was inserted from the outer surface. The montage was submitted to push-out testing up to a complete strip of the bone threads. The cortical t...

PURPOSE The aim of this study was to evaluate the influence of the crown-to-implant (C/I) ratio on the change in marginal bone level around the implant and to determine the site-related factors influencing the relationship between the C/I ratio and periimplant marginal bone loss. METHODS A total of 259 implants from 175 patients were evaluated at a mean follow-up of five years. Implants were ...

Objective We present a unique case of a midline xanthoma of the occipital bone exhibiting atypical imaging characteristics with preserved bone cortex that has not previously been described. Participant This man presented with refractory headaches and suboccipital pain and a mass within the diploe of the occipital bone but with preserved inner and outer cortex of the bone. Magnetic resonance ima...

Making leaves preparations using fresh method, testing with 5% copper acetate, ferric trichloride 10% some grains sodium carbonate. The observations leaf 1 2 have similarities consisting upper epidermis, hypodermis, palisade parenchyma, pa...

to evaluate the effects of supplementation of tomato pomace (tp), canola, soybean and tallow oils on performance, carcass characteristics, and bone parameters of heat stressed broilers, 792 d-old arian broiler were divided to 36 pens. each dietary treatment had 4 replicate with 22 birds each. these factorial experiment (3*3) involved 3 kinds of canola, soybean and tallow oils and 3 levels of 0,...

relative resistance of 43 iranian as well as introduced apple cultivars to blue mold (penicillium expansum) was studied within years 2010-2011. the fruit physicochemical traits were also evaluated as measures of potential resistance to decay. local p. expansum strains were isolated from decayed apple fruits and the most aggressive isolate (5,000 spores ml-1) used as inoculum. fruits were wound-...

this study was conducted to evaluate the effect of soy milk on serum 17- β estradiol level and number of neurons in cerebral cortex and hippocampus as well as determination of the ratio of neurons in cortical and hippocampal regions in neonatal ovariectomized rats. thirty female rats (one day old) were divided into six groups of five. at day 7, ovariectomy surgery was performed in four groups a...

introduction: in islamic countries in the month of holy ramadan many muslims based on their religious legislation refuse fluid intake during the fasting time though instructed to drink after injection of tc-99m methylene-diphosphonates [tc-99m mdp] used for skeletal scintigraphy. we aimed to establish whether fluid restriction in tc-99m mdp skeletal scintigraphy has an impact on its quality. me...
