Evaluation of morpho-anatomical and chemical differences between varieties of the medicinal plant Casearia sylvestris Swartz

Casearia sylvestris Swartz (Salicaceae) é uma planta utilizada na medicina tradicional, cujos extratos de folhas demonstraram importantes ações farmacológicas. A espécie apresenta variação morfológica, genética e química. Duas variedades são consideradas devido a diferenças morfológicas: C. sylvestris var. sylvestris e var. lingua. Há dificuldades na definição destas variedades. O objetivo deste trabalho é avaliar diferenças morfo-anatômicas e químicas entre as variedades de C. sylvestris que permitam sua diferenciação com aplicação farmacêutica ou botânica. Seções transversais e paradérmicas de folhas foram preparadas para análises morfo-anatômicas, histoquímicas e microscopia quantitativa (indices de estômatos e paliçada). Análises cromatográficas (CLAE-DAD e CCD) foram realizadas para obter o perfil de diterpenos clerodânicos. Os resultados das análises morfo-anatômicas demonstraram diferenças significativas entre as variedades somente em cortes paradérmicos: var. sylvestris - paredes celulares epidérmicas poligonais e hipoestomática, var. lingua - paredes celulares epidérmicas arredondadas e anfiestomática. Os índices de estômatos não revelaram diferenças; os valores dos índices de paliçada foram de 2,8 para var. lingua e 3,9 para var. sylvestris. As análises cromatográficas confirmaram resultados prévios, demonstrando predomínio de diterpenos na var. sylvestris. Este trabalho sugere que análises cromatográficas e morfo-anatômicas podem ser ferramentas aplicáveis na distinção das variedades da espécie.

Anatomical changes and audiological profile in branchio-oto-renal syndrome: a literature review

Introduction  Branchio-oto-renal (BOR) syndrome is an autosomal-dominant genetic condition with high penetrance and variable expressivity, with an estimated prevalence of 1 in 40,000. Approximately 40% of the patients with the syndrome have mutations in the gene EYA1, located at chromosomal region 8q13.3, and 5% have mutations in the gene SIX5 in chromosome region 19q13. The phenotype of this syndrome is characterized by preauricular fistulas; structural malformations of the external, middle, and inner ears; branchial fistulas; renal disorders; cleft palate; and variable type and degree of hearing loss. Aim  Hearing loss is part of BOR syndrome phenotype. The aim of this study was to present a literature review on the anatomical aspects and audiological profile of BOR syndrome. Data Synthesis  Thirty-four studies were selected for analysis. Some aspects when specifying the phenotype of BOR syndrome are controversial, especially those issues related to the audiological profile in which there was variability on auditory standard, hearing loss progression, and type and degree of the hearing loss. Mixed loss was the most common type of hearing loss among the studies; however, there was no consensus among studies regarding the degree of the hearing loss.

Anatomical evaluation of the cervical vertebrae of Wistar rats by means of digital radiographs and its correlation with the maturation stages of human cervical vertebrae

INTRODUCTION: Biological age is an important parameter for growth and development assessment. It can be evaluated through the observation of radiographic changes in skeletal maturation of cervical vertebrae. OBJECTIVE: This study aims to: a) verify if there is correlation between growth curve and the stages of bone age of animals used in laboratories, by evaluating radiographs of the cervical vertebrae; b) correlate these stages with their correspondents in humans. METHODS: 35 Wistar rats were evaluated for a period of 160 days, starting at day 22nd (weaning), with cross sections for periodic weighing, length measurement and digital radiography. Radiographs of the cervical vertebrae (C2 and C3) were measured by means of a computer program (Radio IMP). Data were submitted to statistical analysis (ANOVA) and Pearson correlation. RESULTS: Growth spurt was characterized by fast increasing in weight and length. Through ANOVA, differences were observed in the cervical measurements between days 22, 97, 127, 157, 187 and 217 (p <0.001). A high correlation was found between increasing in body length and weight, as well as in cervical vertebrae height (r = 0.86). Increments in concavities of vertebrae were also observed, similar to humans. CONCLUSIONS: There is correlation between body growth and maturation of cervical vertebrae in rats. Despite the continuous development of concavities, it was not possible to clearly identify the 5/6 stages as in studies of cervical vertebrae maturation in humans.

Assessing the effectiveness of 30% sodium chloride aqueous solution for the preservation of fixed anatomical specimens: a 5-year follow-up study

Anatomical specimens used in human or veterinary anatomy laboratories are usually prepared with formaldehyde (a cancerous and teratogenic substance), glycerin (an expensive and viscous fluid), or ethanol (which is flammable). This research aimed to verify the viability of an aqueous 30% sodium chloride solution for preservation of anatomical specimens previously fixed with formaldehyde. Anatomical specimens of ruminant, carnivorous, equine, swine and birds were used. All were previously fixed with an aqueous 20% formaldehyde solution and held for 7days in a 10% aqueous solution of the same active ingredient. During the first phase of the experiment, small specimens of animal tissue previously fixed in formaldehyde were distributed in vials with different concentrations of formaldehyde, with or without 30% sodium chloride solution, a group containing only 30% sodium chloride, and a control group containing only water. During this phase, no contamination was observed in any specimen containing 30% sodium chloride solution, whether alone or in combination with different concentrations of formaldehyde. In the second phase of the experiment, the 30% sodium chloride solution, found to be optimal in the first phase of the experiment, was tested for its long-term preservation properties. For a period of 5years, the preserved specimens were evaluated three times a week for visual contamination, odors, and changes in color and texture. There was no visual contamination or decay found in any specimen. Furthermore, no strange odors, or changes in color or softness were noted. The 30% sodium chloride solution was determined to be effective in the preservation of anatomic specimens previously fixed in formaldehyde.

Atlas interativo do Pontal do Paranapanema: uma contribuição à educação ambiental

A área do Pontal do Paranapanema está localizada no Extremo Oeste do Estado de São Paulo, na região sudeste do Brasil, em uma posição estratégica considerando tanto sua proximidade com os Estados de Mato Grosso do Sul e Paraná quanto o advento do Mercosul - o mercado comum do Cone Sul. No Estado de São Paulo há três áreas muito carentes, uma das quais é o Pontal do Paranapanema, onde têm havido muitos conflitos sociais relativos à posse e propriedade da terra, envolvendo disputas entre o Estado e os latifundiários. Nos últimos anos os trabalhadores rurais têm realizado ocupações nesta região e reivindicado terras - eles criaram um grupo denominado MST (Movimento dos Trabalhadores Rurais Sem Terra), que tem ganhado popularidade e apoio de vários segmentos da comunidade, estando diariamente na mídia (jornais, TV etc). A comunidade acadêmica tem estado consciente e preocupada com esta situação e, portanto, tem desenvolvido estudos e pesquisas sobre o assunto, tanto individualmente quanto através de grupos de pesquisa. Uma das mais importantes Universidades Brasileiras é a Universidade Estadual Paulista (unesp), que tem um de seus campus localizado no município de Presidente Prudente (o qual está localizado no Pontal do Paranapanema). Desde a década de 1960 diversos pesquisadores têm desenvolvido pesquisas técnico-científicas almejando produzir um Atlas do Pontal do Paranapanema em formato convencional. O principal objetivo seria o de reunir, através de mapas topográficos e temáticos, todas as informações geográficas sobre o Pontal do Paranapanema, a fim de servir de base para projetos e planejamentos governamentais (municipais ou estaduais), bem como para o setor privado. O Atlas seria também um produto de informação sobre os recursos naturais e as condições sócio-econômicas desta área, sendo voltado para estudos acadêmico...(Resumo completo, clicar acesso eletrônico abaixo)

Cartografia temática do atlas de sensibilidade ambiental a derramamentos de óleo do litoral paulista

The objective of this paper is the elaboration and implementation of procedures in a cartographic representation related by fundamental of thematic cartography and graphic semiology for the standardization of the Environmental Oil Spill Sensitivity Maps supported by a Geographic Information Systems (GIS) for handling and modeling of a large number of variables. These make up the Environmental Sensitivity Atlas to Oil Spills in Coastal Paulista, and that represents the phenomena that occur in geographic space accurately so as to highlight the importance of each element in the evaluation and protection of areas of greater sensitivity oil. The composition of the cartographic documents considers the Littoral Sensitivity Index (LSI), biological resources and the resources for human use that could be negatively impacted. Thus, the information contained in each map was carefully evaluated before implementation, so that the cartographic representations of various resources, environments, and other ISLs, the reader should issue an immediate message that could be understood clearly, without requiring prior knowledge of specialized. Another aspect was the distribution harmoniously all the elements contained in the document, so that information could be enough without overwhelming it. It was also taken a certain care, so each symbol could be used properly in order that there is no conflict in the information.
