The present nuclear leakage crisis from Japan is a topic to be discussed in present public health. In radiology, the leaked radioactive elements are considered hazard. Here, the author briefly reviews and discusses on two important radio-hazard elements in post nuclear power plant crisis, radioactive iodine and radioactive cesium. Based on previous similar nuclear crisis in Russia, it ...

introduction: one of the sources of natural occurring radiation was soils. the purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. methods & materials: the soil samples was located in chahbahar city in blouchestan of iran, was chosen for studying ...

numerous methods for repair of hypospadias have been introduced. the technique of tubularized incised plate urethroplasty has gained widespread acceptance. in the classical method of tubularized incised plate urethroplasty, to divert urine flow and preventing urethral stenosis, a stent was used, but its necessity is questionable for some surgeons. in this paper we systematically compared the re...

Background: The Ural region is highlighted among other Russian regions for its unfavorable radiation situation and complexity of the overall environmental situation. The source of man-made radioactive contamination is the work of the "Mayak" Production Association. A significant radioactive contamination has happened as a result of several radiation incidents in the early period ...

Technika kominowa (chEVAR) jest jedną z metod leczenia tętniaków aorty brzusznej o krótkiej szyi. W pracy zaprezentowano przypadek chorego, u którego przeciek okołoprotezowy typu IA po uprzedniej implantacji stent-graftu „kominem” do tętnicy nerkowej został skutecznie zaopatrzony stent-graftem 5-branchowym. Technologia branchowa wydaje się optymalnym sposobem przecieków zabiegach chEVAR. Stent-...

conclusions stents would be regarded as a temporary means of reaching the ideal condition for resection and reconstruction in most patients with tracheal stenoses. although an optimal stent has not been introduced yet, we used polyflex stents in most of our patients with tracheal stenosis due to its availability and ease of use. we suggest that this method is safe and less time consuming than i...

conclusion metallic stent placement is a safe and effective procedure for salvage of native hemodialysis fistula after unsuccessful balloon angioplasty. results twenty-one stents were applied. the anatomical and clinical success rate was 100%. seventeen additional interventions were done for 11 (55%) patients due to stent thrombosis or stenosis during follow-up. our 1- and 2-year secondary pate...

BACKGROUND Restenosis after catheter-based revascularization has been demonstrated to be primarily caused by medial and/or intimal smooth muscle cell (SMC) proliferation. The objective of this study was investigate the ability of local emission of beta-particles from a 32P-impregnated titanium "stent" wire source to inhibit vascular SMC and endothelial cell proliferation in cell culture and to ...

Background Restenosis after catheter-based revascularization has been demonstrated to be primarily caused by medial and/or intimal smooth muscle cell (SMC) proliferation. The objective of this study was investigate the ability of local emission of P3-particles from a "P-impregnated titanium "stent" wire source to inhibit vascular SMC and endothelial cell proliferation in cell culture and to det...
