BACKGROUND A previous study revealed elevated serum Immunoglobulin E (IgE) in ketamine related cystitis (KC) patients. IgE might participate the pathogenesis of different types of bladder pain syndromes, including KC and interstitial cystitis (IC). OBJECTIVES To investigate the IgE expression in KC and IC bladder tissue. STUDY DESIGN Prospective evaluation. SETTING The study was conducted...

BACKGROUND Over the last 3 decades, we have seen a paradigm shift in our approach to the treatment of malignancy. During that time, organ conservation protocols have become standard in the treatment of breast cancer, laryngeal cancer, esophageal cancer, anal cancer and soft tissue sarcomas. METHODS Data from reports of bladder preservation protocols were reviewed to evaluate organ preservatio...

This study revealed that in awake chronic spinal cord-injured (SCI) cats reflexes from perigenital skin area to the bladder can be either inhibitory or excitatory. Electrical perigenital stimulation at frequencies between 5 and 7 Hz significantly inhibited large-amplitude rhythmic reflex bladder activity, whereas frequencies between 20 and 40 Hz induced large-amplitude bladder contractions even...

BACKGROUND Bladder transitional cell carcinoma greatly threatens human health all over the world. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) shows a strong apoptosis-inducing effect on a variety of cancer cells including bladder cancer. However, adenovirus-mediated TRAIL expression still showed cytotoxicity to normal cells mainly due to lack of tumor specificity. METHODS ...

MicroRNA-155 (miR-155) is dysregulated in human cancers. In this study, we reported that miR-155 was over-expressed in bladder cancer tissues. We found that miR-155 promoted cell proliferation in vitro and tumorigenesis in vivo. MiR-155 directly reduced the expression of the tumor suppressor DMTF1. The expression of DMTF1 was decreased in bladder cancer tissues. Similar to the restoring miR-155...

AIMS Previous studies using isolated strips of human detrusor muscle identified adjustable preload tension, a novel mechanism that acutely regulates detrusor wall tension. The purpose of this investigation was to develop a method to identify a correlate measure of adjustable preload tension during urodynamics. METHODS Patients reporting urgency most or all of the time based on ICIq-OAB survey...

bladder cancer is the most frequent genitourinary malignancy in iran. environmental and genetic factors are the two factors linked with bladder cancer expansion. the aim of this study was to investigate the role of pten gene and environmental risk factors on the progression and prognosis of bladder cancer.we evaluated 55 tumor specimens and 66 bladder mucosa samples of non-cancerous patients be...

opium use is one of the most common forms of substance abuse in iran and there are some evidence indicating it is a risk factor of transitional cell carcinoma (tcc) of the urinary bladder. the majority of opium users are also cigarette smokers, so consideration of the high prevalence of smoking which is the most important risk factor of tcc of the urinary bladder among opium users is essential ...
