Protein restriction (PR) significantly inhibits spontaneous and chemical carcinogenesis. Several factors seem to be involved in this effect, including a decrease in body weight, cellular proliferation and DNA damage and an increase in antioxidant defenses. The current study was designed to determine modifications in some hepatic cytochromes P450 (CYPs) due(More)
BACKGROUND Intrauterine retention of fetal bones is a rare complication of abortion. Abnormal uterine bleeding, dysmenorrhea and secondary infertility are the usual complaints. In this case the prolonged retention of fetal bones caused chronic pelvic pain. Hysteroscopic removal of the bones resulted in resolution of the chronic pelvic pain. CASE A(More)
Cyclohexanol (CH) is an industrial solvent capable of inducing cytochrome P450 (CYP) enzymes including the CYP2E and CYP2B subfamilies. S9 from CH treated rats is able to activate several N-nitrosamines that are poorly activated by Aroclor 1254, phenobarbital/beta-naphthoflavone (PB/NF) or 3-methylcholanthrene S9 fractions into mutagens detected by the(More)
INTRODUCTION The aim of this study was to perform a verification of the hematology analyzer Sysmex XN-2000 by comparing with the previous XE-5000. This study assessed the precision and carryover on the XN-2000 and the systematic error between the both counters according to desirable biological variability criterion and a flag comparison study. METHODS(More)
Context. Free-floating substellar candidates with estimated theoretical masses of as low as ∼5 Jupiter masses have been found in the ∼3 Myr old σ Orionis open cluster. As the overlap with the planetary mass domain increases, the question of how these objects form becomes important. The determination of their number density and whether a mass cut-off limit(More)
This paper describes a decision support system (DSS) developed to plan the allocation of resources for the Cuban cruise industry in the port of Havana over the near future. Simulation has been applied here to gain a better picture of the connections between the various processes involved in providing necessary services for both passengers and ships, as well(More)
