The responses of human colon tumor cells (clone A) to graded doses of x-irradiation were studied in combination with conventional chemotherapeutic drugs (bleomycin and 5-fluorouracil) after induction of commitment to differentiation by chronic exposure to N-methylformamide (NMF). NMF treated cells show increased radiation sensitivity, particularly in the(More)
The effects of chronic propranolol (Prop) therapy on the postinfarction myocardial hypertrophy of infarcted rats were studied by histological techniques. Male albino rats were submitted to left coronary artery ligation to produce infarction or to sham surgery (Con, N = 6). Infarcted rats (Inf) were divided into 2 groups receiving Prop (2.5 mg/kg, twice a(More)
Human colon tumor cells (clone A) were studied in vitro with regard to modification of dose-dependent cytotoxicity to misonidazole (MISO) treatment by pre-exposure growth in medium containing the differentiation-inducing agent N-methylformamide (NMF). Cells were grown as exponential cultures and were exposed for 2 passages to 170 mM NMF before exposure to(More)
-The aim of the paper is to present a first attempt in using the techniques associated to the Regulatory Impact Analysis in order to enhance the qualitative and quantitative study of the following issue: a preliminary analysis of the regulatory intervention level in the process of smart meters implementation in Brazilian low voltage consumers. Along the(More)
OBJECTIVE The variety of methodologies used to investigate ovariectomized female rats shows different results, which makes a clinical application of these results difficult. The purpose of this work was to evaluate the effect of masticatory effort reduction and of low-calcium diet on maxillary bone turnover of ovariectomized female rats. STUDY DESIGN(More)
UNLABELLED Dekkera bruxellensis hit the spotlight in the past decade mostly due to its rather high ability to adapt to several different fermentation processes. This yeast relies on different genetic and physiological aspects to achieve and preserve its high industrial fitness and some of these traits are shared with Saccharomyces cerevisiae. We have(More)
