Induction of cholesterol biosynthesis by archazolid B in T24 bladder cancer cells.
2014
Abstract Background Resistance of cancer cells towards chemotherapeutics represents a major cause of therapy failure. The objective of our study was to evaluate cellular defense strategies in response to the novel vacuolar H+-ATPase inhibitor, archazolid B. Experimental approach: The effects of archazolid B on T24 bladder carcinoma cells were investigated by combining “omics” technologies (transcriptomics (mRNA and miRNA) and proteomics). Free cholesterol distribution was determined by filipin staining using flow cytometry and fluorescence microscopy. Flow cytometry was performed for LDLR surface expression studies. Uptake of LDL cholesterol was visualized by confocal microscopy. SREBP acti…
Role of Neutral Amino Acid Transport and Protein Breakdown for Substrate Supply of Nitric Oxide Synthase in Human Endothelial Cells
2003
Endothelial dysfunction is often associated with a relative substrate deficiency of the endothelial nitric oxide synthase (eNOS) in spite of apparently high intracellular arginine concentrations. For a better understanding of the underlying pathophysiological mechanisms, we aimed to characterize the intracellular arginine sources of eNOS. Our previous studies in human endothelial EA.hy926 cells suggested the existence of two arginine pools: pool I can be depleted by extracellular lysine, whereas pool II is not freely exchangeable with the extracellular space, but accessible to eNOS. In this study, we demonstrate that the eNOS accessible pool II is also present in human umbilical vein endoth…
Bladder endometriosis: laparoscopic treatment and follow-up
2008
Objectives: This study aims to show the treatment outcome in women affected by isolated bladder endometriosis who underwent laparoscopic surgery in our units. Only women with deep nodules located in the bladder were selected, thus excluding women with deep lesions located in other sites. Study design: Between March 2005 and 2007, women with deep vesical endometriosis, referring to the Departments of Obstetrics and Gynaecology of University Hospitals "G. Martino" of Messina, "Paolo Giaccone" of Palermo and "San Paolo" of Milano, were respectively recruited. A preoperative assessment of the pathology was performed. Women who were concomitantly diagnosed deep nodules of the rectovaginal septum…
RETROVESICAL MASS IN MEN
1999
We review the differential diagnosis and treatment of retrovesical masses in men.During the last 8 years 21 male patients 3 to 79 years old (mean age 47.1) presented with symptoms or signs of a retrovesical mass. Clinical features and diagnostic findings were reviewed, and related to surgical and histopathological findings.The retrovesical masses included prostatic utricle cyst in 3 cases, prostatic abscess in 1, seminal vesicle hydrops in 6, seminal vesicle cyst in 2, seminal vesicle empyema in 3, large ectopic ureterocele in 1, myxoid liposarcoma in 1, malignant fibrous histiocytoma in 1, fibrous fossa obturatoria cyst in 1, hemangiopericytoma in 1 and leiomyosarcoma in 1. In 17 patients …
Anterior/Apical single incision mesh (Elevate™): Surgical experience, anatomical and functional results, and long-term complications
2021
Abstract Objective Pelvic organ prolapse is a common condition among post-menopausal women, and surgery is often the standard treatment proposed. Native tissue vaginal surgery is burdened by a high rate of recurrence, and mesh vaginal surgery has become current practice. The purpose of this study was to evaluate the safety and the effectiveness of the vaginal kit Anterior/Apical single incision mesh Elevate™ for the correction of anterior and apical compartment prolapse. Study design Data of patients with symptomatic anterior vaginal prolapse stage ≥ II, receiving mesh repair with the Anterior/Apical Elevate single incision system between January 2010 and January 2015 were retrieved. Prolap…
Podoplanin serum and urine concentration in transitional bladder cancer
2016
Background Podoplanin (PDP) is a mucin - a type of transmembrane protein expressed in numerous tissues during ontogeny and in adult animals, including the brain, heart, kidney, osteoblasts and lymphoid organs. Objective The aim of this study was to determine podoplanin concentration in the blood serum and urine of patients with bladder cancer. Quantifying podoplanin concentration and its correlation with various clinicopathological parameters may be useful for more accurate predictions and identifying high-risk patients. Methods The present study included 82 patients with bladder cancer confirmed by transurethral resection or cystectomy and 27 healthy volunteers. The Surface Plasmon Resonan…
Segmental resection of distal ureter with termino-terminal ureteric anastomosis vs bladder cuff removal and ureteric re-implantation for upper tract …
2019
OBJECTIVES: To compare overall (OS), cancer-specific (CSS), recurrence free survival (RFS) and post-operative renal function among patients affected by upper tract urothelial carcinoma (UTUC) of the distal (lower lumbar and pelvic) ureter, electively treated with segmental resection and termino-terminal anastomosis (TT) vs bladder cuff removal and ureteral re-implantation (RR). PATIENTS AND METHODS: A multicentre retrospective study, including 84 patients diagnosed with UTUC of the distal ureter and treated with TT or RR, is presented. The primary endpoint was to compare TT and RR in terms of OS, CSS and RFS. As a secondary outcome we compared the post-operative creatinine values as an inde…
Flexible-dose fesoterodine in elderly adults with overactive bladder: results of the randomized, double-blind, placebo-controlled study of fesoterodi…
2013
Objectives: To assess the efficacy and safety of flexible-dose fesoterodine in elderly adults with overactive bladder (OAB). Design: Twelve-week, randomized, double-blind, placebo-controlled trial. Setting: Sixty-one outpatient clinics in Europe, Israel, and Turkey. Participants: Seven hundred ninety-four individuals aged 65 and older (47% male) with OAB symptoms for 3 months or longer, mean of eight or more micturitions and three or more urgency episodes per 24 hours, at least some moderate problems on Patient Perception of Bladder Condition (PPBC), and Mini-Mental State Examination (MMSE) score of 20 or greater. Interventions: Participants were randomized to fesoterodine or placebo for 12…
Gemcitabine in intravesical treatment of Ta-T1 transitional cell carcinoma of the bladder: Phase I-II study on marker lesions
2004
Abstract Objectives To study the ablative activity of intravesical gemcitabine against superficial transitional cell carcinoma of the bladder at different doses and concentrations. Methods A total of 27 patients were treated with intravesical gemcitabine after transurethral resection during which one to three papillary marker lesions were left unresected. Starting 14 days after transurethral resection, six instillations of gemcitabine were given at weekly intervals. Gemcitabine, diluted in 50 mL of saline solution and maintained for 2 hours, was given at the dose of 500 mg, 1000 mg, and 2000 mg in groups of 9 patients each. A complete response (CR) was defined as negative cytology, cystosco…
Vinflunine in Metastatic Urothelial Carcinoma of the Bladder in Progression after a Platinum-Containing Regimen
2019
<b><i>Background:</i></b> Vinflunine is a microtubule inhibitor of the vinca alkaloid class approved for the treatment of urothelial bladder carcinoma after a platinum-containing regimen. <b><i>Methods:</i></b> To evaluate the effectiveness of vinflunine, we enrolled 80 subjects with a histologically confirmed diagnosis of metastatic urothelial bladder carcinoma that had previously undergone chemotherapy with a platinum-containing regimen and had measurable lesions according to the Response Evaluation Criteria in Solid Tumors (RECIST).
