Efeito da polinização manual e natural no híbrido interespecífico (HIE) BRS Manicoré, Moju, Pará.

O híbrido intraespecífico HIE BRS Manicoré é uma palmeira resultante do cruzamento palma de óleo (Elaeis guineensis Jacq) e caiaué (Elaeis oleifera (Kunth) Cortés e Prain), totalmente dependente da polinização assistida, que é feita através da aplicação de pólen sobre as inflorescências femininas em antese (polinização manual). O objetivo deste trabalho foi medir o efeito da polinização assistida em comparação à polinização natural no híbrido intraespecífico, avaliando-se o peso dos cachos na hora da colheita, nº de frutos normais, nº de frutos partenocárpicos e nº de frutos partenocárpicos brancos em 10 cachos polinizados manualmente e 10 cachos expostos à polinização natural. Com esse experimento, espera-se quantificar o déficit de polinização no HIE. A análise dos cachos polinizados naturalmente, apresentaram valores inferiores de frutos normais, frutos partenocárpicos e frutos partenocárpicos brancos, quando comparados aos cachos polinizados de forma manual. Comparando o peso dos cachos na hora da colheita, foi encontrada uma diferença significativa (t=6,84; gl= 24; p= 0,007), na qual, em média, o peso dos cachos polinizados foi 13,98 kg e dos cachos não polinizados 4,69 kg. De acordo com os resultados, pode-se concluir que a polinização assistida na palma de óleo é uma técnica imprescindível para a produção de cachos. É necessário investir em estudos que busquem alternativas de incrementar a polinização natural do HIE.

Acute Toxic Leukoencephalopathy: Potential for Reversibility Clinically and on MRI With Diffusion-Weighted and FLAIR Imaging

OBJECTIVE. Toxic leukoencephalopathy may present acutely or subacutely with symmetrically reduced diffusion in the periventricular and supraventricular white matter, hereafter referred to as periventricular white matter. This entity may reverse both on imaging and clinically. However, a gathering together of the heterogeneous causes of this disorder as seen on MRI with diffusion-weighted imaging (DWI) and an analysis of their likelihood to reverse has not yet been performed. Our goals were to gather causes of acute or subacute toxic leukoencephalopathy that can present with reduced diffusion of periventricular white matter in order to promote recognition of this entity, to evaluate whether DWI with apparent diffusion coefficient (ADC) values can predict the extent of chronic FLAIR abnormality ( imaging reversibility), and to evaluate whether DWI can predict the clinical outcome ( clinical reversibility). MATERIALS AND METHODS. Two neuroradiologists retrospectively reviewed the MRI examinations of 39 patients with acute symptoms and reduced diffusion of periventricular white matter. The reviewers then scored the extent of abnormality on DWI and FLAIR. ADC ratios of affected white matter versus the unaffected periventricular white matter were obtained. Each patient`s clinical records were reviewed to determine the cause and clinical outcome. Histology findings were available in three patients. Correlations were calculated between the initial MRI markers and both the clinical course and the follow-up extent on FLAIR using Spearman`s correlation coefficient. RESULTS. Of the initial 39 patients, seven were excluded because of a nontoxic cause (hypoxic-ischemic encephalopathy [HIE] or congenital genetic disorders) or because of technical errors. In the remaining 32 patients, no correlation was noted between any of the initial MRI markers (percentage of ADC reduction, DWI extent, or FLAIR extent) with the clinical outcome. Three patients had histologic correlation. However, moderate correlation was seen between the extent of abnormality on initial FLAIR and the extent on follow-up FLAIR (r = 0.441, p = 0.047). Of the 13 patients who underwent repeat MRI at 21 days or longer, the reduced diffusion resolved in all but one. Significant differences were noted between ADC values in affected white matter versus unaffected periventricular white matter on initial (p < 0.0001) but not on follow-up MRI (p = 0.13), and in affected white matter on initial versus follow-up (p = 0.0014) in those individuals who underwent repeat imaging on the same magnet (n = 9), confirming resolution of the DWI abnormalities. CONCLUSION. Acute toxic leukoencephalopathy with reduced diffusion may be clinically reversible and radiologically reversible on DWI, and may also be reversible, but to a lesser degree, on FLAIR MRI. None of the imaging markers measured in this study appears to correlate with clinical outcome, which underscores the necessity for prompt recognition of this entity. Alerting the clinician to this potentially reversible syndrome can facilitate treatment and removal of the offending agent in the early stages.
