OBJECTIVE To characterize passive and active changes in detrusor activity in a highly compliant bladder. MATERIALS AND METHODS Bladders from adult female Sprague-Dawley rats were used 5 weeks after lower thoracic (T8) spinal cord transection or a sham-operation. Passive wall properties were assessed by pressure-volume relationships from whole bladders and the tensile response of bladder strip...

OBJECTIVE The bladder can be considered a target organ for testosterone action, and low testosterone levels possibly cause damage to bladder cells. We set out to study whether hypoandrogenism influences bladder wall cell damage in castrated and senile male rats. METHODS Thirty male Wistar rats were divided into three groups of 10 animals each: group I (3 months old), sham animals; group II (2...

REN FRO, J. LARRY. Wuter and ion transport by the urinary bladder of the teleost Pseudopleuronecles americanus. Am. J, Physiol. 228 ( 1) : 52-61. 1975.-Water and ion transport by the isolated teleost urinary bladder were studied. The transepithelial electrical PD across sac-type bladder preparations was unstable, i.e., initially mucosa positive but becoming more negative with time. Perfused bla...

Mylabris is used in clinical therapy, but is always accompanied by cystitis. The toxic effects of mylabris on bladder are attributed to its active principle: cantharidin. In the present study, we explored how cantharidin induces cytotoxicity in the bladder. Human bladder carcinoma cell line T 24 cells were used as target cells, and human colon carcinoma HT 29 cells as native cells. Cantharidin ...

AIM To investigate the histopathologic changes in native bladder and gastrointestinal segment, the relation between histopathologic changes, type of operation and the period passed over operation in patients with bladder augmentation. MATERIALS AND METHODS Twenty consecutive patients were enrolled in this study. Histopathologic evaluation of the cystoscopic mucosal biopsies from native bladde...

The mechanism responsible for active sodium transport in the urinary bladder of the toad appears to be located at the serosal boundary of the epithelial cell layer of the bladder. Studies of the potential step observed at the serosal boundary in the open-circuited state were undertaken in an attempt to define the factors responsible for its production. Glass micropipettes were used to measure t...

Variational models as the Mumford-Shah model and the active contour model have many applications in image segmentation. In this paper, we propose a new multiclass segmentation model by combining the Rudin-Osher-Fatemi model with an iterative thresholding procedure. We show that our new model for two classes is indeed equivalent to the Chan-Vese model but with an adapted regularization parameter...

OBJECTIVE We investigated the role of the glutathione S-transferase A1, M1, P1 and T1 gene polymorphisms and potential effect modification by occupational exposure to different chemicals in Serbian bladder cancer male patients. PATIENTS AND METHODS A hospital-based case-control study of bladder cancer in men comprised 143 histologically confirmed cases and 114 age-matched male controls. Delet...
