This article aims to examine how certain economic and social factors influence short- long-term performance of small medium enterprises (SMEs). SMEs' is defined by using the value added (VA) SMEs, as a percent total VA enterprises. The study targets European Union (EU) countries selected authors following cluster analysis procedure. In order obtain influences, an that carries out three types tests conducted: testing stationarity, cointegration causality between indicators identified...

Chemotherapy (CT) resistance in ovarian cancer is related to multiple factors, and assessment of these factors necessary for the development new drugs therapeutic regimens. In an effort identify such determinants, we evaluated expression approximately 21,000 genes using DNA microarray screening paired tumor samples taken prior after CT treatment from 6 patients with predominantly advanced stage, high-grade epithelial cancer. A subset differentially expressed was selected all data by initial...

Context.—Breast cancer is increasingly treated with neoadjuvant chemotherapy to improve surgical resectability and evaluate tumor response, which assessed histopathologically. Several histopathologic classification systems have been previously described for assessment of treatment response. Objectives.—To test performance in a side-by-side comparison several after clinical outcome. Design.—Sixty-two patients were enrolled randomized trial receiving sequential doxorubicin paclitaxel....

Protein glycosylation perturbations are implicated in a variety of diseases, including cancer. Aberrant cancer is frequently attributed to altered expression polypeptide GalNAc transferases (GalNAc‑Ts) - enzymes initiating mucin-type O-glycosylation. A previous study from our group demonstrated that one member this family (GALNT3) overexpressed epithelial ovarian (EOC), and GALNT3 correlated with shorter progression-free survival (PFS) EOC patients advanced disease. As considerable degree...
