ÁCIDOS LÁTICO E ACÉTICO OBTIDOS A PARTIR DA FERMENTAÇÃO DO LEITE COM Euterpe oleracea Mart. (AÇAÍ) POR Lactobacillus casei Shirota

Previous studies on palm phyllotaxis deal mainly with the mature trunk. The goals of this study are (i) to determine the relationship between the number of parastichies, the divergence angle, and the plastochrone ratio at the level of the shoot apical meristem; (ii) to examine whether there are fluctuations in the divergence angle; (iii) to interpret the significance of phyllotactic parameters with respect to the mode of growth of the apex. The tubular base of the leaf primordium is more or less asymmetrical, and completely surrounds the shoot apical meristem. The phyllotactic system corresponds to a (2, 3) conspicuous parastichy pair. The mean divergence angle per apex varies between 126.9° ± 9.3° (mean ± SD) and 135. 8° ± 8.0°. Divergence angles for all apices fluctuate within a range of 115.89° to 157.33°. The mean plastochrone ratios between apices varies from 1.35 ± 0.18 to 1.58 ± 0.12. The plastochrone ratio at each plastochrone for all apices ranges from 1.09 to 2.00. There is no correlation between the angle of divergence and the plastochrone ratio. There is a fluctuation in the value of the divergence angle that falls within the range predicted by the fundamental theorem of phyllotaxis. The high value of the ratio of the diameter of leaf primordia over the diameter of the apex, and the long plastochrone might explain the lack of correlation between certain phyllotactic parameters.

Vestibular Symptoms

Vestibular migraine (VM) has emerged as one of the major vestibular syndromes. Although probiotics have exhibited beneficial effects on migraine headache, its effect on VM is not clear. This trial aimed to investigate the treatment efficacy of the probiotic Lactobacillus casei Shirota (LcS) on symptoms of VM. 247 VM patients were enrolled, of which 204 eligible patients receiving either LcS or placebo on a daily basis completed the 4 month study. They were re-visited at 2 and 4 months after study initiation to assess treatment outcomes. The primary endpoints were vestibular symptoms, evaluated by the number of vertiginous attacks during the past week, the Vertigo Severity Score (VSS), and Dizziness Handicap Inventory (DHI) scores. The secondary endpoints were anxiety and depressive symptoms, evaluated using Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) scores. Efficacy of LcS over placebo was not obvious at 2 month follow-up. At 4 month follow-up, while both LcS and placebo groups of VM patients displayed alleviated symptoms, the extents of the improvements were significantly better in LcS group than those of placebo group, with regard to vestibular symptoms using DHI and VSS, as well as anxiety and depressive symptoms using BAI and BDI. Although placebo effect cannot be ignored in intervention for VM patients, the probiotic LcS still exhibits considerable efficacy against VM symptoms over a 4 month study period, supporting further clinical study of a larger and more diverse cohort.

Estudaram-se caracteres vegetativos da planta e do palmito de açaizeiros (Euterpe oleracea Mart) cultivados na Estação Experimental de Ubatuba, litoral norte do Estado de São Paulo, Brasil, com o objetivo principal de identificar caracteres não-destrutíveis que possam ser utilizados na seleção de plantas superiores no programa de melhoramento genético dessa palmeira. Entre os dez caracteres estudados, o número de perfilhos, o peso bruto do palmito e os pesos do resíduo basal e do palmito mostraram maior variabilidade (CV acima de 40%). Menor variabilidade foi encontrada para os caracteres número de folhas e circunferência da planta-mãe (CV entre 14 e 18%). O peso, os diâmetros e o comprimento do palmito mostraram-se positivamente correlacionados com a circunferência da planta. Correlação negativa foi evidenciada entre peso bruto do palmito e número de perfilhos e entre esta última variável e o peso do resíduo basal. O número de folhas mostrou correlação parcial significativa apenas com o diâmetro médio do palmito e com o peso do palmito bruto. Entre os caracteres vegetativos não-destrutíveis avaliados, a circunferência da planta foi o que mais contribuiu para a variação apresentada pelo palmito bruto e liquído (peso, diâmetro e comprimento), sendo responsável por mais de 65% da variação do peso bruto, 35% do peso líquido e em tomo de 50% de seu diâmetro. Constitui-se, assim, em um caráter útil, além de não-destrutível e facilmente mensurável, para orientar a seleção de plantas superiores de açaizeiro num programa de melhoramento genético de palmeiras desta espécie.
