Historic buildings have their own specialized and traditional techniques used in their construction. These are not generally practiced in modern buildings. Working with stone is very technical, laborious and time consuming job. It needs sensitivity and perfection both at workers 8and supervisor level. It is required to prepare different stone members in exactly the same size, proportion and des...

BACKGROUND The incidence of kidney stones in children is increasing. While guidelines exist for acute surgical intervention, there is limited data to inform the decision as to when to intervene non-urgently. OBJECTIVES To identify patient and stone characteristics predicting stone surgery in children. DESIGN Retrospective chart review. SETTING Stollery Children's Hospital, Edmonton, Alber...

OBJECTIVE To evaluate the preventive effects of alkaline citrate on stone recurrence as well as stone growth post-ESWL or PCNL in patients with calcium-containing stones. MATERIALS AND METHODS A total of 76 patients with calcium calculi who were stone-free or had residual stones less than 4 mm following ESWL and PCNL were enrolled. All patients were independently randomized into two groups. T...

Transl Androl Urol 2014;3(3):241 www.amepc.org/tau The regulation of dietary and supplemental calcium intake in relation to urinary stone disease is not well understood (1). For instance, why do most patients with primary hyperparathyroidism with markedly increased serum and urinary calcium not have a history of urinary stone disease? There must be other factors involved in stone formation. Cal...

We have investigated urine protein inhibitors of calcium oxalate crystallization to determine whether variations in these proteins are associated with kidney stone disease and whether protein measurements improve the identification of stone formers compared with conventional risk factors (RF). Using Western blotting, we studied variations in the electrophoretic mobility patterns and relative ab...

PURPOSE To determine the predictive value of certain radiological parameters for an objective asssessment of the presence of ureteral stone impaction. MATERIALS AND METHODS Seventy-nine patients with a single proximal ureteral stones were retrieved from the departmental database. Both clinical and particularly radiological data of all cases were well evaluated on this aspect. In addition to t...

C OARCTATION of the aorta often is associated with other lesions or defects of the heart or great vessels which may influence the outcome of surgery. Infrequently, the coarctation occurs at an atypical site. Of the 118 cases to be reviewed in this paper, 56, or, roughly, one in two, present unusual findings. The frequency with which complicating conditions are met makes the search for additiona...

How long-extinct jawless fishes fed is poorly understood, yet interpretations of feeding are an important component of many hypotheses concerning the origin and early evolution of vertebrates. Heterostracans were the most diverse clade of armoured jawless vertebrates (stem gnathostomes), and the structure of the mouth and its use in feeding are the subjects of long-standing and heated controver...

Mutations of the segment polarity group in Drosophila melanogaster produce additional denticles with reversed polarity in every segment of the larval cuticle. We have investigated the effect of mutations in different elements of the bithorax complex on the segmental identity of these additional pattern elements. Our results suggest that they are derived, primarily, from the anterior compartment...

The success of medical therapies may depend on the type of stone. Knowledge of stone composition often dictates the course of treatment followed by the urologist [5,8]. It can shed some light on the nature of stone formation and identify metabolic abnormalities and underlying medical conditions [9]. Stone composition may thus provide the critical insights needed to devise targeted preventative ...
