Effect of follicular fluid supplementation during in vitro maturation on total cell number in bovine blastocysts produced in vitro

This study evaluated the influence of follicular fluid (FF) added to the maturation medium on the quality of bovine embryos produced in vitro. In the first experiment, oocytes were matured in media containing five different FF concentrations with different maturation times and classified according to meiotic progression and migration of cortical granules. In the second experiment, oocytes matured in the same media were fertilized at three different maturation times; thereafter, cleavage and blastocyst rates were evaluated. In the third experiment, oocytes were matured in media containing three different FF concentrations at two different maturation times, and embryo quality, inferred by the ratio of inner cell mass and trophectoderm cells compared with total cell number, was evaluated. Higher FF concentration (75 - 100% FF) slowed meiotic progression and CG migration (control - 78.13% vs. treated - 52.58% and control - 52.7% vs. treated - 11.59%, respectively, at 24 h of maturation). Also, FF at concentration of 75% or 100% had a negative influence on cleavage and blastocyst rates (control - 90.13% vs. treated - 82.64% and control - 35.73% vs. treated - 11.57%, respectively, at 24 h of maturation). The 50% FF resulted in embryos with increased inner cell mass numbers (control - 29.91 vs. treated - 35.49, at 24 h of maturation) and total cell numbers (control - 109.53 vs. treated - 120.67, at 26 h of maturation). Even though higher concentration of FF added to the maturation medium reduced embryonic development rates, in lower concentrations, FF slowed the meiotic progression and migration of CG and contributed to increases in inner cell mass number. Thus, FF added to the maturation medium enhances the number of cells in bovine embryos produced in vitro, especially for inner cell mass.

Analysis of rocuronium in human plasma by liquid chromatography-tandem mass spectrometry with application in clinical pharmacokinetics

Rocuronium (ROC) is a neuromuscular blocking agent used in surgical procedures which is eliminated primarily by biliary excretion. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for analysis of ROC in human plasma. Separation of ROC and IS (verapamil) was performed using an endcapped C-18 column and a mixture of water:acetonitrile:trifluoracetic acid (50:50:0.1, v/v) as mobile phase. Aliquots of 100 mu L of human plasma were extracted at pH 3, using dichloromethane. The lower limit of quantification of 5 ng/mL shows the high sensitivity of this method. Intra- and inter-assay precision (as relative standard deviation) was all <= 14.2% and accuracy (as relative standard error) did not exceed 10.1%. The validated method was successfully applied to quantify ROC concentrations in patients under surgical procedures up to 6 h after the administration of the 0.4-0.9 mg/kg ROC. The pharmacokinetic parameter estimations of ROC showed AUC/dose of 563 mu g min/mL, total clearance of 2.5 mL/min/kg, volume of distribution at steady state of 190 mL/kg and mean residence time of 83 min.

Caries progression and inhibition in human and bovine root dentine in situ

Since the use of bovine instead of human dentine to evaluate cariogenic and anticariogenic substances is not well established, this in situ study was conducted. Eleven volunteers wore palatal acrylic devices containing 4 dentine slabs (2 human and 2 bovine). Sucrose solution (20%) was dripped over all slabs 4 times a day, simulating a cariogenic challenge. Dentifrice slurries, fluoridated or not, were dripped over specified dentine slabs 3 times a day to evaluate caries reduction. After 14 days, the biofilm formed on the dentine slabs was collected for microbiological analysis. In dentine, mineral loss (DeltaZ) and lesion depth (LD) were determined by cross-sectional microhardness and by polarized light microscopy, respectively. The total streptococci and mutans streptococci counts in the biofilm formed either on human or on bovine slabs, whether treated or not with fluoride dentifrice, were not statistically different. The DeltaZ and the LID values of dentine treated with fluoride dentifrice were significantly lower than the values of dentine treated with non-fluoride dentifrice. The differences in the DeltaZ and LD values between the human and bovine dentine were not statistically significant. The results suggest that bovine dentine can be used instead of human to evaluate caries development and inhibition. Copyright (C) 2003 S. Karger AG, Basel.

Identificação e análise da relação entre a utilização de construtos da qualidade e o desempenho e competitividade organizacional

A growing number of companies is adopting quality management systems to achieve better performance and remain competitive in the market. These systems, however, can prove quite complex because they involve different practices and factors. This paper seeks to identify and analyze how each of these factors and practices, defined as quality constructs, influence the performance and competitiveness in the organizational environment and thus contribute to the strategic decisions in the area of quality. To achieve that, a survey was conducted with industrial companies located in the state of São Paulo, and the data was analyzed by a structural equation software. As a result, it was observed that the constructs Customer Focus and Human Resources are the most influent for the competitive criteria of a company, while the constructs Supplier development and Customer Focus exert greater impact on performance

Productivity data were collected, where evidence of quantitative improvements were found in the expedition macro process. Due to a process analysis theme, this paper gives also the thought about process approach, vital step to create a future Quality Management System

Gestão da qualidade na construção civil

Quality Management has become an essential requirement for all companies intending to compete and ensure its place in the labor market. Several tools have been created as a way of ensuring the effectiveness of quality management, in order to control and manage the quality of services and products to ensure a final product with a high degree of competition and quality, besides satisfaction and exceeding customer expectations. Due to the great importance it has at the presente time on the world stage and internationally, civil construction felt the need to eliminate the defects and the lack of quality that have become so common over time to ensure a quality product and it´s customers satisfaction. It was then that this industry began to implement and develop more modern techniques and tools for quality control in construction. Quality achieved position in global market, defining which companies would continue and which companies would leave it, not to mention it became insistently required by the customer. Some tools such as ISO 9000 guided companies seeking a quality management. This presentation will present some of these management tools and their applicability in the civil construction industry. Thus, it will be evident that despite the current resources it is necessary that civil construction professionals abandon the idea that considers quality management a problem and begin thinking about it as a solution to prevent future errors and ensure the quality of their services
