objective: to detect whether the preoperative combined administration of rectal diclofenac and paracetamol is superior to placebo or rectal diclofenac alone for pain after abdominal hysterectomy. materials and methods: ninety female patients (american society of anesthesiologists (asa) physical status i-ii), scheduled for abdominal hysterectomy were recruited to this double blind trial and were...

the micro wire electrical discharge machining (micro wire-edm) process is a modern machining process with various applications in manufacturing micro-parts. the recast layer remaining on the machined surfaces is an inevitable complication of this process. this layer can subsequently affect the machined parts performance. to optimize the recast layer in the micro wire-edm of the molybdenum micro...

The size and length effects of an inclusion on multi-pass copper shaped-wire drawing were investigated. For this purpose, an experimental investigation on optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, wire and inclusion deformations, drawing and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional fi...

The effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. In this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. The results were the minimum interlamellar spacing of 35 nm and maximum ulti...

Autoerotic death is an accidental during sexual pleasure, usually caused by a device or equipment used to enhance pleasure. deaths can be classified as typical atypical. Typical autoerotic occur due asphyxiation mechanical compression, while atypical means other than asphyxiation. Narcissism-associated tube and wire insertion into the urethra rectum are extremely rare. The victim, man in his 40...

in this study, as for the re-casting, surface alloying and re-solidification layer of this alloys at the work piece level machining with wire electro discharge machining (wedm), changes of surface micro hardness with changes of operational parameters has been studied. therefore, study shows using surface alloying phenomena with the diffusion of wire material into the machined surface and select...

conclusions in the first one hour, diclofenac suppository is able to control the fever more efficient than paracetamol suppositories. results the average rectal temperature in the paracetamol group was 39.6 ± 1.13°c, and 39.82 ± 1.07°c in the diclofenac group (p = 0.37). the average rectal temperature, one hour after the intervention, in the paracetamol and the diclofenac group was 38.39 ± 0.89...

background: the superiority of antipyretic efficacy of high dose rectal acetaminophen is not well established yet. objectives: the present study aimed to compare the antipyretic effectiveness of high loading dose (30 mg/kg) and standard dose (15mg/kg) of rectal acetaminophen in febrile children. patients and methods: this triple blind randomized clinical trial was conducted on 76 patients aged ...

background: considering the ease of administration of capecitabne instead of infusional 5fu for concurrent  radiochemotherapy (rct) of rectal cancer, the use of capecitabine has increased significantly in our radiation oncology department in the past years. thus we decided to compare the safety and survival with these 2 drugs by a retrospective review. methods: files of all patients receiving r...

objective: corrosion resistance is among the most important properties of metal alloys used in the oral cavity. consumption of acidic foods reduces the salivary ph and intensifies the corrosion of brackets and orthodontic wires. this study aimed to compare electro galvanic corrosion of different orthodontic brackets and wires and determine the amount of ions released into acidic artificial sali...
