Germination of Phoenix roebelenii Seeds

The Phoenix roebelenii O'Brien is one of the most used plants in the Brazilian landscape. The work aimed to study the effect of different fruit harvesting locations, associated with seven temperature conditions, on the germination of P. roebelenii seeds. The fruits were collected from two different locations: Ilha Solteira, western Sao Paulo State and Jaboticabal in the middle East of the same State. The disseminules (seeds with stucked endocarp) were placed in plastic boxes (gerbox), and the experimental design was entirely randomized in a factorial scheme of 7x2 (seven temperatures conditions: room temperature, constant at 20, 25, 30 and 35 degrees C and alternated at 20-30 and 25-35 degrees C; and two fruit harvesting locations: Ilha Solteira and Jaboticabal, with four replications with 25 seeds each. The disseminules that emitted the germinative intumescence were daily noted until the germinative process got steady, in about 90 days. The germination rate (G%), the germination speed index (GSI), and the means were extracted and compared by the Tukey test. The highest values of germination rate were obtained at 30, 25-35 degrees C and room temperatures. The seeds showed a higher GSI at room temperature. The fruit harvesting locations influenced the germination.

Three-Dimensional Sonographic Assessment of Placental Volume and Vascularization in Pregnancies Complicated by Hypertensive Disorders

Objectives-The purpose of this study was to evaluate the association between placental volumes, placental vascularity, and hypertensive disorders in pregnancy.Methods A prospective case-control study was conducted between April 2011 and July 2012. Placental volumes and vascularity were evaluated by 3-dimensional sonographic, 3-dimensional power Doppler histographic, and 2-dimensional color Doppler studies. Pregnant women were classified as normotensive or hypertensive and stratified by the nature of their hypertensive disorders. The following variables were evaluated: observed-to-expected placental volume ratio, placental volume-to-estimated fetal weight ratio, placental vascular indices, and pulsatility indices of the right and left uterine and umbilical arteries.Results Sixty-six healthy pregnant women and 62 pregnant women with hypertensive disorders were evaluated (matched by maternal age, gestational age at sonography, and parity). Placental volumes were not reduced in pregnancy in women with hypertensive disorders (P > .05). Conversely, reduced placental vascularization indices (vascularization index and vascularization-flow index) were observed in pregnancies complicated by hypertensive disorders (P < .01; P < .01), especially in patients with superimposed preeclampsia (P = .04; P = .02). A weak correlation was observed between placental volumes, placental vascular indices, and Doppler studies of the uterine and umbilical arteries.Conclusions Pregnancies complicated by hypertensive disorders are associated with reduced placental vascularity but not with reduced placental volumes. These findings are independent of changes in uterine artery Doppler studies. Future studies of the prediction of preeclampsia may focus on placental vascularity in combination with results of Doppler studies of the uterine arteries.

A linguagem escrita na perspectiva de educadores: subsídios para propostas de assessoria fonoaudiológica escolar

PURPOSE: to describe a proposal that may contribute to the development of actions promoting health to back Speech therapists performance in school, based on educators' investigation on conceptions about the written language development process. METHOD: descriptive study performed through application of questionnaires in nineteen elementary school teachers in three public schools in a city in the State of Parana. The questionnaires contained questions on the development of written language, factors that favor and/or hinder this process. Data analysis was carried out through transcription of discursive replies and quantification of multiple-choice answers. From the content submitted in the replies, it was possible to create subject areas to be discussed. RESULTS: seven reports (35%) showing that the development process of written language starts at school were recorded; contact with writing was quoted twelve times (30%) as support for the development of written language; individual aspects were reported sixteen times (38%) as causes for learning difficulties; and there were twelve reports (39%) on forwarding to other professionals as a solution for such difficulties. CONCLUSION: educators have lack of fundamental knowledge for their educational practice regarding the literacy process, although most have training being consistent with what is advocated by LDB. It is not possible to generalize this conclusion, due to the small sized study sample.
