Aortic valve repair with either the reimplantation of aortic or root remodelling external annuloplasty procedure is most effective means treating regurgitation and/or aneurysms [...]

segmental resection and end-to-end anastomosis is the treatment of choice for patients suffering from tracheal stenosis for whom conservative management is not planned. a complication of this procedure is tension-induced anastomotic failure. to prevent this complication, maintaining the neck in full flexion by means of a suture between the chin and upper chest is a traditional approach. we have...

an efficient and simple one-pot approach for the synthesis of 3,4-dihydropyrimidin-2-(1h)-one derivatives using antimony trichloride (sbcl3) as a mild catalyst by means of three-component biginelli reaction between β-keto esters, aldehyde derivatives and urea/thiourea under thermal and solvent-free conditions with excellent yields and short reaction times is reported. this methodology offers se...

We develop an automated wavelet-based spectral method for constructing an approximate confidence interval on the steady-state mean of a simulation output process. This procedure, called WASSP, determines a batch size and a warmup period beyond which the computed batch means form an approximately stationary Gaussian process. Based on the log-smoothed-periodogram of the batch means, WASSP uses wa...

myelography is a diagnostic procedure to indicate spinal defects. after the inception of new means of spinal cord imaging, use of myelography has been limited. since there are contraindications for other modalities in some patients, we have to use myelography. the most common complication of myelography is post myelography headache (pmh). many methods have been proposed to alleviate the pain. i...

background: fenestration in the modified fontan operation allows right-to-left shunting, which reduces the fontan pathway pressure and improves cardiac output. however, on account of the fact that persistent right-to-left shunting results in cyanosis and paradoxical emboli, fenestration closure is recommended after recovery from the fontan operation. methods: this study recruited 3 patients who...

lawgiver, for the purpose of penal supporting of national historical-cultural monuments, ratified repeated article 566 of islamic penal code in 1388; which demonstrates three actions of “making fake cases”, “introducing, carrying or storing” and “buying of historical-cultural monuments” as crimes. this criminalizing was necessary and advantageous, but the procedure of criminalizing has some wea...
