CYP21 gene mutations in Brazilian patients with 21-hydroxylase deficiency from the Amazon region

ABSTRACT: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (P450c21, CYP21) accounts for about 95% of all CAH cases. The incidence of CYP21 gene mutations has been extensively studied in the last years, but in Brazil it has been investigated only in Southeast Brazilian patients. This study is the first report on the distribution of CYP21 mutations in patients from the Amazon region. Direct sequencing of the CYP21 gene identified at least one mutation in 96% of the studied chromosomes. The most common mutations found were IVS2-13A/C > G (36%), Q318X (12%), V281L (12%), 1760_1761insT (9%), Cluster E6 (7%), and P30L (7%). The worldwide most common mutations were identified among patients from the Amazon region at frequencies that may be expected for a population resulting from the admixture of Europeans (predominantly Portuguese), African Blacks and Amerindians, in proportions that differ from those estimated for South Brazilian populations. Interethnic mixture may explain the differences in the frequencies of some mutations between Brazilian patients from the Amazon and from the Southeast of the country. However, the differences found may also be due to variation in the number of patients with the different clinical forms of 21-hydroxylase deficiency in the studies carried out so far.

Morphological deformities in the osseous structure in spotted sorubim Pseudoplatystoma coruscans (agassiz & spix, 1829) with vitamin c deficiency

A vitamina C é essencial para dietas de peixe porque muitas espécies não conseguem sintetizá-la. Esta vitamina é necessária par a formação de cartilagem e matriz óssea. Além disso, age como antioxidante e melhora as resposta do sistema imunológico. O presente trabalho investigou os efeitos da suplementação de vitamina C em dietas para alevinos de pintado (Pseudoplatystoma corruscans) pela incidência de deformidades na estrutura óssea e cartilaginosa. O ascorbil polifosfato (AP) foi utilizado como fonte de vitamina C em dietas para alevinos de pintado durante o período de três meses. Seis dietas foram formuladas: uma dieta controle (0 mg de vitamina C / kg) e cinco dietas 500, 1.000, 1.500, 2.000 e 2.500 mg de AP / kg. Os peixes alimentados sem suplementação de vitamina C apresentaram deformidades óssea na cabeça e mandíbula e fragilidade de nadadeiras. Assim, a dieta de 500 mg de AP/kg foi suficiente para prevenir a ocorrência de deformidades, e a ausência desta vitamina prejudica o desenvolvimento ósseo de juvenis de pintados.

Potencial evocado auditivo para diagnóstico de surdez em gato com síndrome vestibular periférica

The brainstem auditory evoked potential is an electrodiagnostic test that allows a functional assessment of the auditory pathways from the middle ear to the brainstem. This test, in veterinary medicine, is not commonly used in Brazil. This paper reports the use of auditory evoked potential for deafness detection in a cat with unilateral peripheral vestibular syndrome secondary to otitis media.

Carbohydrate production and transport in cotton cultivars grown under boron deficiency

An adequate supply of boron (B) is required for the optimal growth and development of cotton (Gossypium hirsutum L.) plants, but the low phloem mobility of B limits the possibilities of correcting B deficiency. There are indications that different cotton cultivars could have different responses to B deficiency. The differences in responses of cotton cultivars to B regarding photoassimilate production and transport were studied in a greenhouse experiment with nutrient solution. Treatments consisted of three cotton cultivars (FMT 701, DP 604BG and FMX 993) and five concentrations of B (0.0, 2.5, 5.0, 10.0 and 20.0 mu mol L-1). Sampling began at the phenological stage B1 (first square) and continued for four weeks. The leaf area and the number of reproductive branches and structures decreased due to B deficiency. A higher level of abortion of reproductive structures was observed under B deficiency. Boron deficiency increased the internal CO2 concentration but decreased the transpiration rate, stomatal conductance and photosynthesis. Despite the decrease in photosynthesis, nonstructural carbohydrates accumulated in the leaves due to decreased export to bolls in B-deficient plants. The response to B deficiency is similar among cotton cultivars, which shows that the variability for this trait is low even for cultivars with different genetic backgrounds.

Effects of physiotherapy on balance and unilateral vestibular hypofunction in vertiginous elderly

Background: We aimed to analyze the effect of a physical therapy protocol on unilateral vestibular hypofunction and overall balance in elderly with vertigo. Methods: The study included nine subjects, four male subjects (68.5 ± 11.09 years old) and five females (72.4 ± 7.09 years old). It was used the performance-oriented Mobility Assessment (POMA), to evaluate the balance and the Unterberger – Fukuda test for analysis of unilateral vestibular dysfunction through rotations and displacements of the body. We developed and applied a structured physical therapy protocol, consisting of group exercises. Results: It was observed that after the protocol, all participants improved balance (33.9 ± 5.1 vs. 47.3 ± 7.6, p < 0.0001) and displacement (111.1 ± 38.0 vs. 53.3 ± 34.6, p = 0.0001). However, it was not found significant differences for rotation. Conclusion: The proposed protocol has contributed to an improvement in balance and vestibular dysfunction of the aged.

Foram analisados 100 dentes primeiros molares e 100 dentes segundos molares superiores, direitos e esquerdos, permanentes, extraídos de humanos, com o objetivo de explorar a região anatômica da furca, mais especificamente realizar medidas das distâncias das aberturas das furcas vestibular, mesial, e distal até à junção esmalte-cemento, e das distâncias das referidas aberturas até às faces radiculares pertinentes: vestibular, mesial, distal e lingual. Utilizou-se para mensuração um microcomputador 486 DX-66Mhz, no qual estava instalado um software analisador de imagens Mocha-Jandel Scientific SigmaScan Pro, version 2.0. Em relação às distâncias das aberturas das furcas até à junção esmalte-cemento foi observado que as distâncias médias para a furca vestibular foram de 3,50mm e 3,03mm; para a furca mesial de 4,44mm e 4,69mm; para a furca distal de 4,26mm e 3,73mm, respectivamente para os primeiros e segundos molares superiores. Em relação às distâncias das aberturas das furcas até às faces radiculares pertinentes foi observado que as distâncias médias da furca vestibular até à face mesial da raiz mesio-vestibular foram de 3,78mm e 3,72mm; da furca vestibular até a face distal da raiz disto-vestibular 3,62 e 3,64mm; da furca mesial até à face vestibular da raiz mesio-vestibular 7,33mm e 6,89mm; da furca mesial até a face lingual da raiz lingual de 4,13mm e 4,33mm; da furca distal até à face vestibular da raiz disto-vestibular de 5,61mm e 5,09mm; da furca distal até a face lingual da raiz lingual de 4,73mm e 4,65mm, respectivamente para os primeiros e segundos molares superiores.

A Concordância verbal e suas repercussões avaliativas nas redações de vestibular

This paper attempts to quantify the occurrences of verb agreement, as well as evaluative repercussions on a sample of one hundred and eight essays compiled by candidates entering the São Paulo State University- UNESP in 2006 through an annual entrance exam conducted by the Foundation and applied for Vestibular the Unesp - VUNESP in November 2005. Our reflections are observing about the possible relationships between the performances obtained in newsrooms observed (high, medium and low) and precepts found in the rules established by normative grammars. Our study is based on theoretical and methodological framework of variationist sociolinguistics and search through the quantification of data, discuss the factors that influence verb agreement in the corpus analyzed. Our results show not only a high index of cases of verbal agreement (standard variant) in the three types of essays analyzed, as well as cases of overcorrection that may be explained by the misapplication of the rules of agreement

O acesso à universidade pública no Brasil e a questão social: uma análise dos dados do relatório do vestibular da Universidade Estadual Paulista Julio Mesquita Filho UNESP

This work has as a central concern in analyze the causes of the still limited access of young Brazilians to public higher education in socioeconomic and cultural.In Brazil, onçy 14,4% of the young between 18 and 24 years old attend this educational level.If we consider that the public university offer just 1/4 of the vacancies, can be affirmed that this institutions are not able to attend neither 4% of the young between 18 and 24.Brazil shows,in this level of education,a lower access that most of its neighbors: Argentina(40%), Venezuela(26%), Chile(20%),Bolivia(20%).In this work were analyzed the data reports of entrance exam of Universidade Estadual Paulista (Unesp) entre 2004 e 2009,prepared by Fundaçao para o Vestibular da Universidade Estadual Paulista(Vunesp). In this analysis,can be noted the influence of some aspects socioeconomic and cultural related to possibilities os the young acces to public univercity. Stand out among these: family income,the possibility to dadicate only to studies and attend preparatory courses,as well as the parents level of education.

Trajetória social de alunos de um curso pré-vestibular popular

The aim of the research that originated this article was the analysis of the social trajectory of students from a public preparatory course and the verification of their expectations about higher education. Data collection was based on a questionnaire with open and closed-ended questions and a semi-structured interview, based on the models used by Muzzetti (1997). Data were analyzed by the elaboration of thematic charts. Based on the researches conducted by Pierre Bourdieu (1997, 2007), this research concluded that the students understand that schooling is, besides being a viable alternative in the search for social ascension, the redeeming of social ills. Profession choice based on natural talent or divine gift generate expectations which attest the lack of knowledge about the school system by students and their parents, which is reinforced by the belief in opportunity equality.

Da invenção do vestibular aos cursinhos populares: um desafio para a orientação profissional

This article is based on the sociological and historical approach of the origin of the university entrance exams in Brazil and shows the preparatory courses (preps) expanding simultaneously as a strategy of the lower and middle classes to get their children into university. Thus, the paradox of an antipedagogical practice becomes an essential condition for students to have access to prestigious university courses, what justifi es the historical movement by the lower and middle classes to appropriate this practice.. We propose that measures are taken to improve the results of important affi rmative actions that aim to enable students to enter university, as well as highlight Professional Guidance as a necessary resource which constitutes a new challenge in this fi eld of action.
