background: in this experimental study, the radiographic and biomechanical characteristics of osteoperforated rabbit tibia during bone repair period were investigated. materials and methods: using dental drills, 2 mm holes were drilled at the mid-shaft of right tibia in 12 new zealand white rabbits. the left tibia was intact and selected as the control. x-rays of the left and right tibias were ...

DYOPTYKA’s innovative solution for the reduction of speckle noise in projection displays, using a phase randomizing deformable mirror, is shown to achieve good performance both within a single 1 μs pulse duration and through sequences of such pulses.

background: given the paucity of data on possible testis changes in opioid dependents, we sought to compare the testis volumes between a group of opium dependents and a group of healthy controls. objective: comparison of testis volume between opium dependents and healthy controls. materials and methods: this case-control study recruited 100 men with opium dependency (cases) and 100 healthy men ...

Background: A lot of investigations exist on the biological effects of radiofrequency and microwave radiation however only a few studies have considered non-carcinogenic exposure to radiations specifically from mobile phones.

mucosa-adhesive gels can be used as a useful mean of delivering drugs to or via mucosal membranes, and in particular buccal mucosa. carbomers are among the best mucosa-adhesive materials known. the aim of this study was to compare the results obtained from the mucosa-adhesive strength of aqueous gels containing carbomers, either alone or in combination, to the data obtained from assessing the d...

the partition coefficients (p-values) of certain new potential, stereoselective, reversible, long-acting local anesthetics have been determined in an n-octanol/ phosphate buffer system. these are derivatives of 2-phenoxyethyldialkylamine hydrochloride, and almost all of them are readily soluble in water. their aqueous solutions have shown different absorption maxima, and these have been used qu...

in this quasi-experimental study, we assess the effect of sodium bicarbonate solution on onset and duration of anesthesia with the use of lidocaine and adrenaline solution in surgical patients undergoing epidural anesthesia
