Diabetic cystopathy is a common complication of diabetes mellitus, but little is known of the mechanisms responsible for the bladder dysfunction. Therefore, the effect of streptozotocin-induced diabetes on urinary bladder function was investigated. Bladders from 2-month diabetic rats were significantly larger than those from age-matched controls. Protein(More)
In construction industry, laminated glass is more and more used for transparent loadbearing building components. It is known that the residual load-carrying capacity after glass breakage of glass/PVB (polyvinyl butyral) laminates is relatively poor, mainly due to the limited stiffness and strength of PVB. For that reason, the failure behaviour of laminates(More)
For many structural glass components, buckling is known to be a major design issue, which is influenced significantly by several parameters. The latter include boundary conditions, slenderness and geometrical imperfections, in particular initial curvatures. However, in spite of their importance for building practice, experimental data for the latter are(More)
Germ cell testicular tumors constitute a highly lethal group of neoplasms. Although recent diagnostic and therapeutic developments have altered the prognosis in this disease, delay in diagnosis and occasional mismanagement of patients continue to inhibit further improvement in survival. A ten-year retrospective study of germ cell tumors of the testis at(More)
Idiopathic female intersex presents in the neonate with characteristic anomalies of the external genitalia, complete and separate phallic and vaginal urethras and vesical outlet obstruction. Management of this disorder should initially focus upon adequate urinary drainage and proper sex assignment in the neonate. Successful management and surgical(More)
Xanthogranulomatous pyelonephritis may present as a renal mass which can be difficult to differentiate from a hypovascular renal tumor by intravenous pyelography or selective renal angiography. Four patients are described in whom ultrasonography with or without fine-needle aspiration suggested or confirmed the diagnosis of xanthogranulomatous pyelonephritis.
Renal tumors invading the inferior vena cava have proved to be surgically challenging. For suprahepatic and right atrial involvement, deep hypothermic circulatory arrest (HCA) has been the favored procedure. Retrograde cerebral perfusion (RCP) was combined with moderate HCA in an effort to improve cerebral protection and avoid neurological sequelae. Six(More)
The spontaneously diabetic adult male Abyssinian-Hartley guinea pig develops bladder hypertrophy and voiding dysfunction. In contrast to animals with chemically induced diabetes, this animal demonstrates changes in bladder function in the absence of diuresis. The diabetic guinea pigs void a total daily volume similar to that of control animals, but have a(More)
Curved glass is traditionally formed in a prefabricated mould at elevated temperatures. More recently, also cold-bending processes have been developed, in which flat glass panes can be bent at the building site. The main advantages of cold-bending processes are the reduced material costs, the ease of transportation and the production speed. “Freeform glass”(More)
The percutaneous approach to the renal pelvis provides access for antegrade urography, percutaneous nephrostomy, or endourologic manipulation. Having performed 31 successful procedures, including the percutaneous placement of double-pigtail ureteral stents for ureterovesical obstruction, we advocate the combined use of ultrasonography and fluoroscopy to(More)
