BACKGROUND Gold standard treatment for symptomatic gall stones is laparoscopic cholecystectomy (LC). Ultrasonically activated devices have been used for gall bladder dissection in LC. Harmonic scalpel (HS) is the leading ultrasonically cutting coagulation device offering surgeons important benefits. The main aim of our study was to compare the surgical outcomes of LC performed by HS to that per...

PURPOSE Edwin Beer introduced the first endoscopic treatment of papillary bladder tumors in 1910. This historical review describes how his landmark discovery paved the way for office cystodiathermy to treat recurrent papillary tumors. MATERIALS AND METHODS The medical writings of Edwin Beer and all studies pertaining to the treatment of papillary bladder tumors from 1879 to the present were r...

In this study, a combined electro-(Fenton/coagulation/flotation) (EF/EC/El) process was studied via degradation of Disperse Orange 25 (DO25) organic dye as a case study. Influences of seven operational parameters on the dye removal efficiency (DR%) were measured: initial pH of the solution (pH0), applied voltage between the anode and cathode (V), initial ferrous ion concentration (CFe), initial...

Background. Interventional endoscopy has largely reduced mortality in patients with peptic ulcer hemorrhage. Study aims. To evaluate the efficacy and safety of endoscopic hemostasis with argon plasma coagulation and injection sclerotherapy in bleeding peptic ulcer and determine the mortality of patients in a prospective, controlled study. Patients and methods. The study includes 100 patients wi...

Abstract Widely used in chemical product manufacture, 1,4-dioxane is one of the emerging contaminants, and it poses great risk to human health ecosystem. The aim this study was degrade 1,4-dioxiane using a pulsed switching peroxi-coagulation (PSPC) process. electrosynthesis H2O2 on cathode Fe2+ production iron sacrifice anode were optimized enhance degradation. Under current densities 5 mA/cm2 ...

Abstract In this study , palladium nano-particles were electro deposited galvano - statically on carbon black powder (Vulcan XC -72R). The catalytic activity for electro - oxidation of ethanol and methanol in alkaline media were studied by cyclic voltammetry and linear sweep voltammetry techniques. The results indicated that the electro-oxidation of ethanol and methanol strongly depends o...

among the most common types of problematic soils, are probably the expansive ones. one of the modern methods of strengthening and improving the soil in place is the use of electro-osmotic improving treatment. this paper presents the design of an apparatus suitable for electro-osmotic treatment. a soil sample of a high expansive potential was compacted and the effect of electro-osmotic treatment...
