Objective: This study is aimed to evaluate craniofacial features in patients with Fanconi anemia (FA) through cephalometric analysis and to classify the facial growth pattern to observe possible facial discrepancies. Design: This is a cross-sectional study which employed a quantitative approach to compare linear and angular measurements of cephalometric analysis in lateral teleradiographic images of a clinical type sample of patients with FA. A retrospective cephalometric study was performed using cephalometric analyses of Ricketts and Steiner; growth patterns according to Ricketts' vertical growth pattern (VERT index) were also analyzed. Patients: Fifty patients diagnosed with FA who were undergoing anti-aplasia treatment at the outpatient Hematology service at the Federal University of Parana , Curitiba, Brazil were included in the study. Interventions: The patients were evaluated in the School of Dentistry of the Pontifical Catholic University of Parana (PUCPR), Curitiba, Brazil. Exclusion criteria included patients who had used or were using growth hormone medication, had undergone bone marrow transplant, or had been previously subjected to dental treatment. Main Outcome Measures: Cephalometric points were plotted in order to set up linear and angular cephalometric measurements. Angular and linear measurements from 17 factors proposed by Ricketts' cephalometric analysis were assessed. Results: Dolicofacial appearance was observed in 52% of individuals; braquifacial in 28%, and mesofacial in 20%. Significant maxillary/mandibular discrepancy was observed. It was concluded that upon anteroposterior evaluation of facial bone structures, the FA sample presented smaller median measurements in most variables evaluated; it also presented mandibular micrognathism and mainly dolicofacial vertical growth pattern. These findings, together with other features such as skin pigmentation and microphthalmia, may lead to a possible recognition of a FA condition from a patient's facial features. © Copyright 2014 American Cleft Palate-Craniofacial Association.

This paper aims to evaluate vertical and horizontal distribution of fungi population in Subtropical Ombrophilous Forest and Pinus taeda plantation, separately. The experiment had been improved in the municipality of Tijucas do Sul, PR, with 2 factors and 3 replications. The evaluated factors were depth (litter, transition zone and soil) and seasons (winter and summer). The Subtropical Ombrophilous Forest toposequence was divided in plain, hillside and top, where it was placed a 10,000 m2 plot; which was subdivided in one hundred subplots. It was selected five alleatory samples which composed the simple samples, and, as they were randomized, they composed one block sample unit. The P. taeda plantation exhibited a topographic sequence that was classified as plain, and the same topography was used for the following sampling. The microorganism's population analyses revealed differences between depths, it was higher in the litter and in the summer. The fungi population presented no differences between seasons in the P. taeda plantation, it was higher in the litter. It was identified a higher fungi population in the Subtropical Ombrophilous Forest compared to the results observed in the plantation.

This article presents an in-depth bibliographic study about the creation, principles, evolution, and practices of the lean philosophy oriented to the services sector. More than 70 papers about "lean thinking" - specially with focus on services - have been carefully reviewed. It presents the principles of lean service in an organized way, companies applying lean service, and best practices and tools in the implementation of lean service. It shows that lean service does not have a single or specific model of tools, practices or standards. In fact, it is a mix of tools and practices that must be applied according the situation found to be improved. Despite the lack of a standards and methodology for use in services, its best practices, inherited from manufacturing, when applied to services can generate large economic and financial results, as well as improvement of workers' behavior. But, like any change process, this study shows that the application of lean in services also suffers resistance. There might be limitations when evaluating lean practices and principles to services, specially those that have not yet been well defined and reported. Other limitations are due to the scarce articles in the literature. However, this research showed that the use of the lean philosophy in services proved to be effective and quite worthwhile. Several cases analyzed presented significant gains and confirmed an increasing and promising future for service companies "thinking lean".

The objective of this research was to evaluate the dormancy dynamic of peach tree 'Chimarrita' and plum tree 'Poli Rosa' buds in a region of low chill occurrence. The stems were collected in an orchard in Fazenda Rio Grande, State of Parana, Brazil, from April to August of 2007 and 2008. In the last date, an additional group of stems was collected and maintained in a refrigerator (4 to 7°C) by 672 hours. The evaluation of dormancy was observed by the biological test of single node cuttings under controlled conditions of temperature (25°C) and photoperiod (16 h). The quantification of chilling hours (CH) and the chilling units (CU) occurred in the region were performed. The two species were evaluated separately, as two separate experiments. The experimental design was completely randomized, with 9 treatments for peach tree buds and 11 treatments for plum tree buds, both with four replications. The two years were analyzed individually. The more intense endodormancy period of peach tree buds occurred in May 2007 and 2008. The more intense endodormancy period of plum tree buds occurred in May 2007, and it was extended until June 2008.

The objective of the research was to determine an index of dormancy (ID) of temperate climate fruit trees buds for evaluation of the biological test of single node cuttings. The biological tests had been done from April to September of 2007 and 2008 with plum, peach, persimmon, kiwi and grape trees. Based in the values of average time for budburst (ATB), velocity of budburst (VB), final rate of budburst (FR), rate of vigorous budburst (RVB) and its correlations, the ID was developed for the five species. The interpretation classes of dormancy were separate in deep, intense, moderate, weak and absent. The ID developed for evaluation of the biological test of temperate climate fruit trees buds demonstrated to be an important tool for interpretation of the results with higher precision.
