Physical quality of seeds of Moquiniastrum polymorphum / Qualidade física de sementes de Moquiniastrum polymorphum

Abstract This study aimed to analyze the physical properties of the seeds of Moquiniastrum polymorphum when processed by mini-SAS, X-ray and seed blower systems. The seeds were purchased from Seeds Caiçara, located in Penápolis-SP. After purchase, the seed lot was characterized by standard tests. In the X-ray test the seeds were classified according to their internal morphology as filled, unfilled or malformed. The seed blower was set at six opening settings, resulting in light and heavy fractions. The evaluations were performed by weighing the seeds that remained in the blower (heavy fraction) and by the amount of filled seeds indicated by the X-ray test. The germination tests were composed of four replicates of 50 seeds. The mini-SAS was used for external evaluation. It was concluded that the combined use of the seed blower and the X-ray test was efficient for the evaluation and determination of the physical quality of the seeds of M. polymorphum. The seed blower at opening settings 5 resulted in the best lot quality. The external parameters were not able to qualitatively evaluate the seeds of M. polymorphum.

Resumo O presente estudo objetivou analisar as propriedades físicas das sementes de Moquiniastrum polymorphum por meio dos equipamentos raios-X, mini-SAS e soprador de sementes. As sementes foram adquiridas da empresa Sementes Caiçara em matrizes localizadas no município de Penápolis-SP. Após adquirido e beneficiado, o lote de sementes foi caracterizado por meio de testes padrões. No teste de raios-X as sementes foram classificadas de acordo com sua morfologia interna como cheias, vazias ou mal formadas. O soprador de sementes foi ajustado em seis aberturas, resultando em frações leves e pesadas. As avaliações foram realizadas pesando-se as sementes que permaneceram no soprador (fração pesada) e pela quantidade de sementes cheias pela análise de raios-X. Posteriormente foram realizados testes de germinação compostos por quatro repetições de 50 sementes. Na avaliação externa das sementes utilizou-se o equipamento mini-SAS. Após análise dos dados, concluiu-se que a utilização em conjunto dos equipamentos soprador de sementes e raios-X foi eficiente para avaliação e determinação da qualidade física das sementes de M. polymorphum. O soprador de sementes na regulagem da abertura 5 resultou na melhor qualidade do lote. Os parâmetros externos não foram capazes de avaliar qualitativamente as sementes de M. polymorphum.

Similar hypotensive responses to resistance exercise with and without blood flow restriction.

Low intensity resistance exercise (RE) with blood flow restriction (BFR) has gained attention in the literature due to the beneficial effects on functional and morphological variables, similar to those observed during traditional RE without BFR, while the effects of BFR on post-exercise hypotension remain unclear. The aim of the present study was to compare the blood pressure (BP) response of trained normotensive individuals to RE with and without BFR. In this cross-over randomized trial, eight male subjects (23.8 ± 4 years, 74 ± 3 kg, 174 ± 4 cm) completed two exercise protocols: traditional RE (3 x 10 repetitions at 70% one-repetition maximum [1-RM]) and low intensity RE (3 x 15 repetitions at 20% 1-RM) with BFR. Blood pressure measurements were performed after 15 min of seated rest (0), immediately after and 10 min, 20 min, 30 min, 40 min, 50 min and 60 min after the experimental sessions. Similar hypotensive effects for systolic BP (SBP) were observed for both protocols (P < 0.05) after exercise, with no differences between groups (P > 0.05) and no statistically significant difference for diastolic BP (P > 0.05). These results suggest that in normotensive trained individuals, both traditional RE and RE with BFR induce hypotension for SBP, which is important to prevent cardiovascular disturbances.

Dydrogesterone does not reverse the cardiovascular benefits of percutaneous estradiol.

OBJECTIVE: To evaluate the influence of dydrogesterone on estimated cardiovascular risk of users of hormone replacement therapy (HRT) (with percutaneous 17ß-estradiol in monotherapy and in combination with dydrogesterone) and HRT non-users through the Framingham score tool for a period of 2 years. METHODS: Framingham scores were calculated from the medical records of patients treated for at least 2 years with 17ß-estradiol alone or in combination with dydrogesterone, along with HRT non-users, through the analysis of patient medical records, followed for at least 2 years at Instituto Estadual de Diabetes e Endocrinologia Luiz Capriglione. RESULTS: Improvements in lipid profile, glucose and blood pressure levels, which reduced the estimated cardiovascular risk, were observed in the 17ß-estradiol group. Similar changes were observed in the users of 17ß-estradiol + dydrogesterone, suggesting that this progestogen does not attenuate the effects caused by 17ß-estradiol. CONCLUSIONS: Both HRT groups showed a reduction in their Framingham score. In contrast to data from other HRT investigations on cardiovascular risk, these formulations proved to be safe, even in the first year of use.

Alteracoes psiquiatricas no hipertireoidismo: revisao da literatura e apresentacao de casos

A importancia do estudo das relacoes entre o cerebro e o sistema endocrino e o seu impacto sobre o comportamento e um dos objetivos principais da nova disciplina chamada psiconeuroendocrinologia. Dentre os varios hormonios estudados, aqueles provenientes do eixo tireoidiano tem recebido uma atencao especial. Os autores apresentam uma revisao da literatura referente aos aspectos psiquiatricos dos transtornos tireoidianos e apresentam cinco casos de hipertireoidismo (Doenca de Basedow-Graves) que cursaram com transtorno mental organico. Dois destes casos apresentaram-se como 'delirium'e os outros tres foram diagnosticados como sindrome organico do humor (maniaco). A evolucao e a conduta terapeutica dos casos sao discutidas de acordo com literatura revista.

Some urinary tract disease in Australian aboriginal inpatients in 1980.

Four hundred and ninety-three patients were admitted to the Royal Darwin Hospital in 1980 with urinary tract disease. Aboriginals had an increased incidence (p less than 0.005) of urinary tract infection and glomerulonephritis (p less than 0.001) compared with non Aboriginals. Aboriginals with post-streptococcal glomerulonephritis tended to grow Group A Beta hemolytic streptococci from their skins, non Aboriginals tended to grow it from their throats. Aboriginals had a lower incidence of urolithiasis (p less than 0.001). There was no difference in the incidence of benign prostatic hypertrophy between the two populations.

Disposicao da veia interventricular anterior em relacao a ponte miocardica. / Anatomical relationship between the interventricular vein and the myocardial bridges

Os autores estudam a relacao entre a veia interventricular anterior e ponte miocardica Para o estudo, foram dissecados 50 coracoes colhidos em sala de necropsia. Destes, 29 (58%) apresentavam ponte miocardica sobre o ramo interventricular anterior da arteria coronaria esquerda. Em 27 deles a veia situouse sobre as fibras musculares da ponte, a esquerda da arteria interventricular anterior.Em apenas dois coracoes, um deles apresentando duas pontes, a veia tambem se dispos sob as fibras musculares. Os autores chamam a atencao para esta disposicao venosa, ate entao nao referida, quando discutem a importancia da ponte muscular como fator de isquemia miocardica e realcam a importancia destes dados de sintopia durante a cirurgia da revascularizacao do miocardio
