Preoperative short-course radiotherapy in rectal cancer patients: results and prognostic factors

Objective The purpose of this study was to evaluate the clinical outcome of preoperative short-course radiotherapy for rectal cancer patients. Methods The study group comprised 210 patients with pathologically proven resectable rectal cancer. Between 2001 and 2013, they were treated preoperatively with short-course radiotherapy (25 Gy delivered in five fractions), followed by total ...

Energy-based analysis of permanent strain behaviour of cohesive soil under cyclic loading

Ecological strategy for soil contaminated with mercury

) (Sas-Nowosielska et al. 2008) and hydrogen sulphide were recorded in each tube. The results were correlated with probability tables. The MPN of the bacterial population was expressed as counts per gram ... nitrates into atmospheric nitrogen. The number of sulphur-amino acid decomposing bacteria was found to be in an inverse correlation with root mercury uptake in soil from the chlor-alkali plant (Sas

Analysis of the Behavior of Mitochondria in the Ovaries of the Earthworm Dendrobaena veneta Rosa 1839

We examined six types of cells that form the ovary of the earthworm Dendrobena veneta ogonia, prooocytes, vitellogenic oocytes, trophocytes, fully grown postvitellogenic oocytes and somatic cells of the gonad. The quantitative stereological method revealed a much higher “volume density” of mitochondria in all of the types of germ-line cells except for the somatic cells. Fluorescent ...

Organisation of the endosperm and endosperm–placenta syncytia in bladderworts (Utricularia, Lentibulariaceae) with emphasis on the microtubule arrangement

Multinucleate cells play an important role in higher plants, especially during reproduction; however, the configurations of their cytoskeletons, which are formed as a result of mitosis without cytokinesis, have mainly been studied in coenocytes. Previous authors have proposed that in spite of their developmental origin (cell fusion or mitosis without cytokinesis), in multinucleate ...
