Paradoxical interaction between cancer and long-term postsepsis disorder: impai...

Side-effects of irinotecan (CPT-11), the clinically used drug for colon cancer ...

Intestinal mucositis (IM) is the critical side effect of irinotecan (CPT-11), which is the front-line drug used for the treatment of colorectal cancer. This study aimed to evaluate the effectiveness of latex proteins (LP) from Calotropis procera to prevent IM and diarrhea in animals. Swiss mice were treated daily with saline or LP (1, 5, or 50 mg/kg, i.v.) 24 h prior to CTP-11 (75 mg/kg/4 days, i.p) and for add...

Interleukin-18 (IL-18) is equally expressed in inflammatory breast cancer and n...

Aim: Inflammatory breast cancer (IBC) is the most aggressive form of locally advanced breast can- cer. The signs of inflammation such as hyperemia and hyperthermia might suggest the possible participation of inflammatory mediators. This study investigates stromal and tumor expression of nuclear factor-kappa B (NF-B) and interleukin-18 (IL-18) in samples obtained from IBC and noninflammatory locally advanced breast...

A novel model of megavoltage radiation-induced oral mucositis in hamsters: role...

Clostridium difficile toxin A attenuates Wnt/B-Catenin signaling in intestinal ...

Clostridium difficile toxins A and B (TcdA and TcdB) are homologous glycosyltransferases that inhibit a group of small GTPases within host cells, but several mechanisms underlying their pathogenic activity remain unclear. In this study, we evaluated the effects of TcdA on the Wnt/ -catenin pathway, the major driving force behind the proliferation of epithelial cells in colonic crypts. IEC-6 and RKO cells stimul...

Progressive loss of E-cadherin immunoexpression during cervical carcinogenesis

PURPOSE: To investigate E-cadherin immunoexpression during cervical carcinogenesis. METHODS: We assessed the immunohistochemical expression of E-cadherin in squamous intraepithelial lesions (SIL - 52 cases), squamous cell carcinoma (SCC) of the uterine cervix (23 cases) and also in eight cases of cervicitis. RESULTS: The results show very different E-cadherin membrane expression levels when cervicitis (88%), SI...

Flavonoides rutina e quercetina reduzem a perda óssea alveolar na doença period...

Periodontitis is an inflammatory disease associated with bone loss and is a frequent cause of tooth loss in adults. Flavonoids are compounds abundant in vegetables and have anti- inflammatory actions. The aim of the present study was to investigate the role of flavonoids rutin and quercetin on the pathogenesis of experimental periodontal disease (EPD). EPD was induced in Wistar rats by placing a nylon thread ar...

Central giant cell lesion of the jaws : study of CCND1 gene amplification and p...

Central giant cell lesions (CGCLs) are uncommon benign jaw lesions with uncertain etiology and a variable clinical behavior. In neoplasms, alterations in molecules involved in the G1/S checkpoint are frequently found. Loss of p16INK4a expression or overexpression of cyclin D1 may stimulate cell proliferation. The purpose of this study was to analyze CCND1 gene amplification and the expression of p16INK4a in CGC...

Cyclooxygenase-2 expression on ifosfamide-induced hemorrhagic cystitis in rats

Purpose Hemorrhagic cystitis (HC) is a limiting side effect of chemotherapy with ifosfamide (IFS). In this study, we investigated the participation of cyclooxygenase-2 (COX-2) upon ifosfamide-induced HC. Methods Male Wistar rats (150-200 g; six rats per group) were treated with saline, IFS (400 mg/kg, i.p.) and analyzed by changes in bladder wet weight, macroscopic and microscopic parameters, and COX-2 expressi...
