Abstract Transforming growth factor–β (TGF-β) isoforms are factors that function physiologically to regulate development, cellular proliferation, and immune responses. The role of TGF-β signaling in mammary tumorigenesis is complex, as has been reported both a tumor suppressor promoter. To elucidate the gland tumorigenesis, metastasis, gene encoding type II receptor, Tgfbr2, was conditionally deleted epithelium (Tgfbr2MGKO). Loss Tgfbr2 results lobular-alveolar hyperplasia developing...
Abstract Mechanisms of androgen dependence the prostate are critical to understanding cancer progression independence associated with disease mortality. Transient elevation transforming growth factor-β (TGF-β) occurs after ablation. To determine role TGF-β on response ablation, conditional type II receptor knockout mouse models epithelia (Tgfbr2NKX3.1KO) and stromal fibroblasts (Tgfbr2fspKO) were used. After castration, prostates Tgfbr2NKX3.1KO mice had apoptosis levels similar those...

Purpose To improve spatial resolution and image quality of diffusion‐weighted (DW) MRI in detecting low‐risk prostate cancer (lrPC) patients undergoing active surveillance protocol (AS‐PC), we propose the application a diffusion‐prepared balanced steady‐state free precession (bSSFP) technique capable multishot acquisition. Methods Diffusion‐prepared bSSFP was compared with single‐shot DW echo planar imaging (SS‐DW‐EPI) at two prescribed resolutions (2.1 × 2.1 3.5mm 3 , 0.9 3.5 mm ) nine...
Rapid bladder growth associated, partial urethral obstruction and embryonic development entail stromal-epithelial interactions involving signaling by the cytokine transforming factor-beta (TGF-beta). However, to our knowledge role of TGF-beta in stromal hyperplasia hypertrophy is not understood.In an effort understand specific stroma a fibroblast conditional knockout mouse type II receptor gene, Tgfbr2(/spko), was generated using Cre-lox methodology. Bladders from 18, 7 8-week-old mice were...
ObjectivesHigh-resolution prostate imaging may allow for detection of subtle changes in tumor size, decrease the reliance on biopsies, and help define boundaries during ablation. This pilot clinical trial evaluates a novel high-resolution MRI small, biopsy-proven tumors.MethodsOur team developed software that can be loaded any modern to generate high resolution diffusion-weighted sequences (HR-DWI), which were compared standard sequence (S-DWI) prospective active surveillance patients....
We examined the role of transforming growth factor-beta in urothelial and bladder development. Transforming signaling was attenuated compartment subsequent effects were a tissue recombination model.Urothelium cultured from adult rat bladders transfected with control vector C7Delta or mutant DNIIR (dominant negative receptor II). Grafts created by recombining urothelium plus embryonic day 18 mesenchyma placed beneath renal capsule athymic mouse hosts. harvested at 21 42 days. Final tissues...
The purpose of this study was to determine the impact resident teaching on outcomes mid-urethral sling surgery.A retrospective review female patients who underwent an outpatient transobturator (TOT) synthetic procedure with and without concomitant prolapse repair by two surgeons (JA, KE) in a tertiary pelvic medicine practice performed. Total time (TPT = from incision closure including placement any procedure), estimated blood loss (EBL), postoperative complications urinary retention, mesh...
To describe our initial experience with a novel modification of the Mitrofanoff conduit technique utilizing Yang-Monti ileovesicostomy and serosa lined extramural tunnel T-pouch to create continent catheterizable stoma in patients prior enterocystoplasty.A 14 cm segment bowel was harvested, distal 4 divided reconfigured technique. The remaining folded into U secured serosal basting stitch. Half tube is laid trough U-shaped secured. Next, incised along anti-mesenteric border for length tube....
