BACKGROUND To assess the prognostic value of progesterone receptor (PR) expression in patients with hormone receptor-positive and human epidermal growth factor receptor 2 (HER2)-negative breast cancer subgroups. METHODS A retrospective review of breast cancer patients who underwent mastectomy or breast-conserving surgery between January 1998 and December 2007 was performed. The prognostic imp...

objective: the organotypic co-culture is a well-known technique to examine cellular interactions and their roles in stem cell proliferation and differentiation. this study aims to evaluate the effects of dermal fibroblasts (dfs) on epidermal differentiation of adipose-derived stem cells (ascs) using a three-dimensional (3d) organotypic coculture technique. materials and methods: in this experim...

OBJECTIVES Diabetic foot ulcer (DFU) is a common complication of diabetes and not only an important factor of mortality among patients with diabetes but also decreases the quality of life. The short form of Diabetic Foot Ulcer Scale (DFS-SF) provides comprehensive measurement of the impact of diabetic foot ulcers on patients' health related quality of life (HRQoL). The purpose of this study was...

BACKGROUND Only 4 prospective randomized phase 3 trials have been reported for anal cancer. A prognostic factor analysis for anal cancer from a prospective database has been published from only 1 study (N = 110). To confirm and uncover new prognostic factors, we analyzed the prospective database of intergroup RTOG 98-11. METHODS Univariate and multivariate analyses of the baseline characteris...

PURPOSE On initial publication of GI Intergroup Radiation Therapy Oncology Group (RTOG) 98-11 [A Phase III Randomized Study of 5-Fluorouracil (5-FU), Mitomycin, and Radiotherapy Versus 5-Fluorouracil, Cisplatin and Radiotherapy in Carcinoma of the Anal Canal], concurrent chemoradiation (CCR) with fluorouracil (FU) plus mitomycin (MMC) decreased colostomy failure (CF) when compared with inductio...

We introduce delegatable functional signatures (DFS) which support the delegation of signingcapabilities to another party, called the evaluator, with respect to a functionality F . In a DFS,the signer of a message can choose an evaluator, specify how the evaluator can modify thesignature without voiding its validity, allow additional input and decide how the evaluator canfurther...

Introduction Evidence produced by researchers is not comprehensibly used in practice. National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care for Nottinghamshire, Derbyshire and Lincolnshire's strategy for closing the research to practice gap relies on the use of 'Diffusion Fellows' (DFs). DFs are seconded from the local healthcare economy to act ...

BACKGROUND Accurate and useful predictors of gastric carcinoma treated with neoadjuvant chemotherapy are lacking at present. We aim to explore the potential prognostic significance of the neutrophil-to-lymphocyte ratio (NLR) in advanced gastric cancer receiving S-1 plus oxaliplatin (SOX) or oxaliplatin and capecitabine (XELOX) regimen. METHODS We enrolled 91 patients with advanced gastric can...
