Stones in the biliary tree may coexist with gall-bladder stones, may be found only in the common duct (in the absence of gall-bladder stones) or, more rarely, may be present in the intrahepatic biliary tree-as in the Caroli syndrome.1 One of the most frequent causes of choledocholithiasis, however, is the retained common duct stone which has been left behind inadvertently after elective or emer...

conclusions in patients with abdominal or pelvic masses and a history of previous abdominal surgery, the possibility of gossypiboma should be kept in mind. case presentation we report two patients (the first patient was 50 years old, with a history of an appendectomy three years ago in another city; the second patient was 52 years old, with a history of a cesarean section 25 years ago in anothe...

background ureteral stents are widely used in many urologic practices. however, stents can cause significant complications including migration, fragmentation, and encrustation and it may possibly be forgotten. successful management of a retained, encrusted stent requires combined endourological approaches. objectives to present our experience with the approaches for treating forgotten ureteral ...

To investigate the effects of certain factors on the rate of retained placenta, 2844 calving records from 1288 Holstein cows in a herd were used. These cows calved during year period of 2001 to 2007. A generalized statistical linear model was applied to analyze the data. Logistic regression model was applied as the statistical model. In the model, fixed effects of year, season (warm or cold) an...

This study was conducted in order to investigate the influence of plastic deformation on the transformation of retained austenite in a TRIP steel with a high content of Al and a low content of Si. To the aim, appropriate treatments were used to produce the starting material (TRIP steel). The microstructure of the obtained steel was composed of bainite and phases including ferrite and retained a...

We analyze a well known type of puzzle in planar geometry: given a planar shape, it is required to find a cut that divides the shape into two identical parts (up to rotation and translation). Clearly not all shapes can be so dissected and for some shapes that appear in puzzles the cutting curve is quite surprising and difficult to find. In this paper we first analyze the inverse problem of asse...
