Pharmacodynamic measures of neutropenia, such as absolute neutrophil count at nadir and neutrophil survival fraction, may not reflect the overall time course of neutropenia. We developed a pharmacokinetic-pharmacodynamic model to describe and quantify the time course of neutropenia after administration of topotecan to children and to compare this with nonhuman primates (NHPs) as a potential pre...
in order to know the environmental behaviour of toxic pollutants it is fundamental to understandthe role of chemical components of a material on sorption of such pollutants.in this study, the sorption of amix of polycyclic aromatic hydrocarbons (pahs) by cork fractions (i.e. raw cork (cf), free extractive cork(fef) and nonsaponifiable (desf)) has been investigated to better understand the role ...
rosa damascena has been found to act on central nervous system including the brain. several studies confirm that r. damascena inhibits the activity of the hypothalamus and pituitary systems in rat and can suppress the central nervous system. in traditional medicine hypnotic effect of rose is also suggested. in this study, the hypnotic effect of the ethanol crude extract of r. damascena and its ...
the aim of the present study was to investigate the effect of gender on the distribution of pancreatic islets in native chicken. ten adult male and ten adult female isfahan native chickens were used in this experiment. results showed a distinct sexual dimorphism in the native chicken pancreas which depends upon the various fractions of the pancreatic lobes, which were occupied by alpha, beta an...
to investigate the patterns of dna ploidy and proliferating activity in breast cancer and relate them to other prognostic factors, paraffin blocks of 53 cases of breast carcinoma were studied. cancer cells obtained by mechanical tissue disaggregation were examined for dna content, ploidy and s-phase fraction. dna assay was done using a cas interactive image analyzing system. all of the cases sh...
acknowledge the importance of e-commerce to their countries and to survival of their businesses and in creating and encouraging an atmosphere for the wide adoption and success of e-commerce in the long term. the investment for implementing e-commerce in the public sector is one of the areas which is focused in government‘s action plan for cross-disciplinary it development and e-readiness in go...
Porphyra dentata, an edible red macroalgae, is used as a folk medicine in Asia. This study evaluated in vitro and in vivo the protective effect of a sterol fraction from P. dentata against breast cancer linked to tumor-induced myeloid derived-suppressor cells (MDSCs). A sterol fraction containing cholesterol, β -sitosterol, and campesterol was prepared by solvent fractionation of methanol extra...
Literature regarding the outcome of maxillary sinus floor elevation to create sufficient bone fraction to enable implant placement was systematically reviewed. Bone fraction and implant survival rate were assessed to determine whether grafting material or applied growth factor affected bone fraction. Trials where sinus floor elevations with autogenous bone (controls) were compared with autogeno...
PURPOSE We describe midterm outcomes after division of secondary chords (chordal cutting) combined with downsized ring annuloplasty for ischemic mitral regurgitation (IMR). METHODS We compared the clinical outcomes in patients who underwent chordal cutting with downsized ring annuloplasty (CC-group, n = 15) and those who underwent conventional ring annuloplasty only (Conventional-group, n = 3...
OBJECTIVE Plasma high-density lipoprotein (HDL) level is inversely correlated with the risk of atherosclerosis. However, the cellular mechanism by which HDL exerts antiatherogenic actions is not well understood. In this study, we focus on the lipid components of HDL as mediators of the lipoprotein-induced antiatherogenic actions. METHODS AND RESULTS HDL and sphingosine 1-phosphate (S1P) stimu...
