cystoscopy and urinary cytology are currently the basis for diagnosis and ‎follow-up of bladder tumors. research to find a sensitive and specific tumor ‎marker for diagnosis of bladder tumor is actively underway, however, due to low sensitivity ‎and high cost of cytology. this cross-sectional study was performed in 65 patients to evaluate whether urinary bladder ‎cancer (ubc) antigen level can ...

تعیین حد روباز-زیرزمینی برای کانسارهایی با گسترش عمقی از سطح زمین و امکان استخراج زیرزمینی، یکی از اولین تصمیماتی است که باید در فرآیند طراحی معدن اخذ شود. راهکار ارائه شده توسط nilsson (1982 و 1992) برمبنای انتخاب عمقی که در آن مجموع ارزش خالص فعلی (npv) دو روش روباز و زیرزمینی بیشینه باشد، عمل می‎نماید. در این تحقیق پس از اعمال اصلاحاتی در راهکار نیلسون و تعیین پارامترهای لازم، الگوریتم و مدل...

Background Tobacco use accounts for the majority of urinary bladder cancer (UBC) cases both in men and women. It is widely accepted that smokers have increased risk of UBC [1-4]. An early diagnosis of UBC is crucial because patients with superficial UBC have much better prognosis than those with invasive UBC [1,2,4,5]. During the past years a variety of urine based markers have been introduced ...

Disruption of the polyubiquitin gene Ubc leads to a defect in fetal liver development, which can be partially rescued by increasing the amount of ubiquitin. However, it is still not known why Ubc is required for fetal liver development and the nature of the defective cell types responsible for embryonic lethality have not been characterized. In this study, we assessed the cause of embryonic let...

Urothelial bladder cancer (UBC) is a common genitourinary malignancy. MiR-31, a well-identified miRNA, exhibits diverse properties in different cancers. However, the specific functions and mechanisms of miR-31 in UBC have not been investigated. In this study, tumor samples, especially invasive UBC, showed significantly reduced level of miR-31, as compared with normal urothelium. Prognostic anal...

The anaphase-promoting complex or cyclosome (APC/C) is a multi-subunit ubiquitin ligase that regulates the eukaryotic cell cycle. APC/C belongs to the RING finger class of ubiquitin ligases that function by interacting with a ubiquitin-conjugating enzyme (Ubc), thus inciting the Ubc to transfer ubiquitin onto a target protein. Extensive studies with APC/C in other organisms have identified seve...

Rationale: Chemoresistance and subsequent recurrence of human urothelial bladder cancer (UBC) is partially driven by a subpopulation of tumor initiating cells, namely cancer stem cells (CSCs). However, the underlying molecular mechanism in chemotherapy-induced CSCs enrichment and following chemoresistance and recurrence remains largely unclear. Methods: Gemcitabine and cisplatin (GC) chemoresis...

The University of British Columbia (UBC) became the first university in Canada to develop a strategy for enhancing global access to its technologies. UBC's University-Industry Liaison Office, in collaboration with the UBC chapter of Universities Allied for Essential Medicines (UAEM), established a mandate and developed principles that provide the developing world with access to UBC technologies...

Urothelial bladder cancer (UBC) is the most common urinary neoplasm in China. CCN family protein 2 (CCN2), a cysteine-rich matricellular protein, is abnormally expressed in several cancer types and involved in tumor progression or chemo-resistance. However, detailed expression patterns and effects of CCN2 in UBC still remain unknown. We found that down-regulation of CCN2 suppressed proliferatio...
