Formas de preparo de figo-da-índia minimamente processado¹

O trabalho teve como objetivo avaliar a influência da forma de preparo na conservação pós-colheita de figos-da-índia minimamente processados. Foram utilizados figos-da-índia maduros de polpa alaranjada, provenientes de pomar comercial da região de Valinhos-SP. Após a seleção, os frutos foram lavados e higienizados em solução com Sumaveg® a 200 mg 100g-1 de cloro livre, por 5 minutos. Em seguida, os frutos foram levados à câmara fria, a 12±2°C, onde permaneceram por 12 horas prévias ao processamento. O processamento constituiu na retirada da casca e das extremidades para a obtenção dos frutos inteiros. Para a obtenção das metades, foi realizado um corte no sentido longitudinal da fruta descascada e, para obtenção das rodelas, foram realizados cortes, a cada 2 cm, transversais à altura do fruto descascado. Os tratamentos assim obtidos foram acondicionados em contentores de tereftalato de polietileno transparente e com tampa, com capacidade de 1.000 mL (marca Neoform® N-94). As embalagens foram armazenadas em expositores refrigerados a 3°C, por um período de 16 dias, sendo as análises realizadas a cada 4 dias. O delineamento adotado foi o inteiramente casualizado, num esquema fatorial 3x5: três processamentos e cinco datas de amostragem (0;4;8;12 e 16 dias), com três repetições por tratamento. Avaliaram-se a perda de massa fresca, os teores de sólidos solúveis (SS), acidez titulável (AT), a relação (SS/AT), ácido ascórbico, além da análise sensorial dos produtos. Os frutos inteiros foram os preferidos quanto à intenção de compra e apresentaram melhores resultados quanto ao teor de sólidos solúveis, de acidez titulável, relação sólidos solúveis/acidez titulável e teor de ácido ascórbico. A maior perda de massa fresca foi verificada no processamento em rodelas.

Novos derivados do sistema heterocíclico 1H-pirazolo[3,4-b]piridina: síntese e assinalamentos de hidrogênios e carbonos por RMN 1D e 2D

The synthesis and NMR analysis of seven new 4-(aryl)amino-5-carboethoxy-1,3-dimethyl-1H-pyrazolo[3,4- b]pyridines (7-13) are described. The synthetic approach used involved the preparation of intermediates 5-aminopyrazol (4), the enamine derivative (5) and the 4-chloro-1H-pyrazolo[3,4-b]pyridine (6). Compounds (7-13) were obtained by treatment of 6 with the desired aniline. The structures of new heterocyclic compounds and their precursors intermediates were assigned on the basis of spectral analysis including 1D and 2D NMR experiments [¹H; 13C{¹H} and DEPT; ¹H x ¹H - COSY; ¹H x13C - COSY, nJ CH, n = 1, 2 or 3 (HETECOR and COLOC)].

Determinação da 2,5-hexanodiona em amostras de urina submetidas à hidrólise ácida: importância da coluna cromatográfica e do pH do meio

Acidic hydrolysis of samples is frequent in urinary 2,5-hexanodione determination. This hydrolysis should be performed under proper conditions, in order to avoid interference, such as the presence of 2,5-dimethylfurane and 2-acetylfurane. The results of the present work, as well as data from the literature, show that the use of non-polar or slightly polar chromatographic columns of 30 m length is an essential condition for 2,5-HD determination in an acid hydrolysed urine sample. In the same way the pH should be kept between 0.3 and 0.5. The mean concentrations of 2,5-HD in samples submitted to hydrolysis (0.50 ± 0.28 mg/g of creatinine) was about 3 times higher than those found in the samples without acid hydrolysis (0.19 ± 0.3 mg/g of creatinine).

Eletrodo íon-seletivo para determinação potenciométrica de alumínio(III) em meio de fluoreto

The construction and analytical evaluation of a coated graphite Al(III) ion-selective electrode, based on the ionic pair formed between the Al(F)n3-n anion and tricaprylylmethylammonium cation (Aliquat 336S) incorporated on a poly(vinylchloride) (PVC) matrix membrane are described. A thin membrane film of this ionic pair and dibutylphthalate (DBPh) in PVC was deposited directly on a cylindric graphite rod (2 cm length x 0.5 cm diameter) attached to the end of a glass tube using epoxy resin. The membrane solution was prepared by dissolving 40% (m/m) of PVC in 10 mL of tetrahydrofuran following addition of 45% (m/m) of DBPh and 15% (m/m) of the ionic pair. The effect of membrane composition, fluoride concentration, and several concomitants as potential interferences on the electrode response were investigated. The aluminium(III) ion-selective electrode showed a linear response ranging from 1.4 x 10-4 to 1.0 x 10-2 mol L-1, a detection limit of 4.0 x 10-5 mol L-1, aslope of -54.3±0.2mV dec-1 and a lifetime of more than 1 year (over 3000 determinations for each membrane). The slope indicates that the ion-selective electrode responds preferentially to the Al(F)4- species. Application of this electrode for the aluminium(III) determination in stomach anti-acid samples is reported.

Metodologias eletroanalíticas para a determinação de herbicidas triazínicos por voltametria de onda quadrada e técnicas de deconvolução

This work describes the development of electroanalytical methodologies for the determination of atrazine, ametrine and simazine by square wave voltammetry on a mercury electrode. For pure atrazine and pure ametrine, the detection limits (DL) were 3.7 and 4.3 µg L-1, respectively, while they increased to 4.8 and 6.5 µg L-1 in the presence of 3.0 x 10-6 mol L-1 of the other component (a mathematical deconvolution program was used in the mixture cases). The voltammetric response for simazine could not be separated from that of atrazine and measurements were carried out only in pure simazine solutions (DL: 7.5 µg L-1).

Development of a flotation-spectrophotometric method for determination of cetylpyridinium chloride in pharmaceutical products

A new simple and sensitive flotation-spectrophotometric method for the determination of cetylpyridinium chloride (CPC) is reported. The method is based on the formation of an ion- associate between CPC and Orange II (OR) which is floated in the interface of aqueous phase and n-hexane by vigorous shaking. The aqueous solution was discarded and the adsorbed ion associate on to the wall of a separating funnel was dissolved in a small volume of methanol solvent and its absorbance was measured at 480 nm. The apparent molar absorptivity (Ε) of the ion associate was determined to be 4.12 x 10(5) L mol-1 cm-1. The calibration graph was linear in the concentration range of 15-800 ng mL-1 of CPC with a correlation coefficient of 0.9988. The limit of detection (LOD) was 10.8 ng mL-1. The relative standard deviation (RSD) for determination of 100 and 800 ng mL-1 of CPC was 3.47 and 2.04% (n=7), respectively. The method was successfully applied to the determination of CPC in a commercial mouth washer product.

Determinação espectrofotométrica por injeção em fluxo de compostos fenólicos em águas residuárias empregando peroxidase de abobrinha (Cucurbita pepo)

Empregou-se nesse trabalho alguns vegetais como fonte de peroxidase. Após a determinação de proteína total, atividade e atividade específica, selecionou-se o extrato bruto da abobrinha (Cucurbita pepo) como fonte dessa enzima para ser empregado em um sistema de análise por injeção em fluxo com detecção espectrofotométrica para a determinação de diversos compostos fenólicos (e.g. fenol, catecol, 2,4-diclorofenol, 4-cloro-3-metilfenol, 4-acetamidofenol, 4-clorofenol, 2,4,6-triclorofenol, o-cresol, m-cresol, p-cresol e hidroquinona). Após a otimização desse sistema em fluxo, o mesmo foi empregado na determinação de compostos fenólicos em águas residuárias de indústrias da região de São Carlos-SP, no intervalo de concentração de 2,0x10-4 a 4,0x10-3 mol L-1, com LD de 8,0x10-5 mol L-1 e freqüência analítica de 58 h-1. A recuperação de fenol em 3 amostras variou de 98,3 a 106, 2% e o RSD foi menor que 1,2% para soluções de fenol nas concentrações de 6,0x10-4 e 8,0x10-4 mol l-1 (n=10).

Spectrophotometric determination of lansoprazole in pharmaceuticals using bromate-bromide mixture based on redox and complexation reactions

Two sensitive spectrophotometric methods are described for the determination of lansoprazole (LPZ) in bulk drug and in capsule formulation. The methods are based on the oxidation of lansoprazole by insitu generated bromine followed by determination of unreacted bromine by two different reaction schemes. In one procedure (method A), the residual bromine is treated with excess of iron (II), and the resulting iron (III) is complexed with thiocyanate and measured at 470 nm. The second approach (method B) involves treating the unreacted bromine with a measured excess of iron (II) and remaining iron (II) is complexed with orthophenanthroline at a raised pH, and measured at 510 nm. In both methods, the amount of bromine reacted corresponds to the amount of LPZ. The experimental conditions were optimized. In method A, the absorbance is found to decrease linearly with the concentration of LPZ (r = -0.9986) where as in the method B a linear increase in absorbance occurs (r = 0.9986) The systems obey Beer's law for 0.5-4.0 and 0.5-6.0 µg mL-1 for method A and method B, respectively. The calculated molar absorptivity values are 3.97µ10(4) and 3.07µ10(4) L mol-1cm-1 for method A and method B, respectively, and the corresponding Sandell sensitivity values are 0.0039 and 0.0013 µg cm-2. The limit of detection (LOD) and quantification (LOQ) are also reported for both methods. Intra-day and inter-day precision, and accuracy of the methods were established as per the current ICH guidelines. The methods were successfully applied to the determination of LPZ in capsules and the results tallied well with the label claim and the results were statistically compared with those of a reference method by applying the Student's t-test and F-test. No interference was observed from the concomitant substances normally added to capsules. The accuracy and validity of the methods were further ascertained by performing recovery experiments via standard-addition method.

Histopathological, immunohistochemical, and molecular study of BHV-5 infection in the central nervous system of experimentally infected calves

Bovine meningoencephalitis caused by BHV-5, a double-stranded DNA enveloped virus that belongs to the family Herpesviridae and subfamily Alphaherpesvirinae, is an important differential diagnosis of central nervous diseases. The aim of this study was to describe the histological changes in the central nervous system of calves experimentally infected with BHV-5 and compare these changes with the PCR and IHC results. Formalin-fixed paraffin-embedded central nervous system samples from calves previously inoculated with BHV-5 were microscopically evaluated and tested using IHC and PCR. All the animals presented with nonsuppurative meningoencephalitis. From 18 evaluated areas of each calf, 32.41% and 35.19% were positive by IHC and PCR, respectively. The telencephalon presented more accentuated lesions and positive areas in the PCR than other encephalic areas and was the best sampling area for diagnostic purposes. Positive areas in the IHC and PCR were more injured than IHC and PCR negative areas. The animal with neurological signs showed more PCR- and IHC-positive areas than the other animals.

Eficiência do 2,4-D aplicado isoladamente e em mistura com glyphosate no controle da trapoeraba

A trapoeraba (gênero Commelina) é planta daninha-problema em cafezais devido à sua capacidade de sobreviver nas mais diversas condições e tolerância ao herbicida glyphosate. O objetivo deste trabalho foi avaliar a eficiência do herbicida 2,4-D, em doses crescentes, aplicado isoladamente ou em mistura com o glyphosate, no controle de Commelina benghalensis e Commelina diffusa. Para isso, foi conduzido um experimento para cada espécie, em vasos, em casa de vegetação, no delineamento inteiramente casualizado, com cinco repetições. Foram comparados dez tratamentos, que consistiram da combinação de cinco doses de 2,4-D (0; 167,5; 335; 670; e 1.005 g ha-1) e duas doses de glyphosate (0 e 720 g ha¹). Avaliou-se a eficácia dos tratamentos pela porcentagem de controle, avaliada em cinco épocas, em relação à testemunha. Em C. benghalensis, 2,4-D proporcionou controle excelente (>91%) aos 33 DAT (dias após tratamento) a partir de 167,5 g ha-1 na presença de glyphosate e a partir de 335 g ha-1 na ausência de glyphosate. Em C. diffusa, 2,4-D proporcionou controle excelente aos 33 DAT a partir de 670 g ha-1, tanto na presença quanto na ausência de glyphosate. No entanto, somente a mistura de 2,4-D + glyphosate a 1.005 + 720 g ha-1 provocou 100% de controle desta espécie, verificando-se rebrota das plantas nos outros tratamentos. Nas condições dos experimentos, C. benghalensis mostrou-se mais suscetível que C. diffusa ao herbicida 2,4-D aplicado isoladamente ou em mistura com o glyphosate. Portanto, a identificação da espécie de trapoeraba presente na área a ser tratada e o conhecimento de sua biologia auxiliam na escolha do melhor produto e da dose ideal a ser aplicada, ou mesmo na escolha da mistura adequada, garantindo menor custo e melhor controle, com menores riscos para a cultura e o meio ambiente.

Category fluency test: effects of age, gender and education on total scores, clustering and switching in Brazilian Portuguese-speaking subjects

Verbal fluency tests are used as a measure of executive functions and language, and can also be used to evaluate semantic memory. We analyzed the influence of education, gender and age on scores in a verbal fluency test using the animal category, and on number of categories, clustering and switching. We examined 257 healthy participants (152 females and 105 males) with a mean age of 49.42 years (SD = 15.75) and having a mean educational level of 5.58 (SD = 4.25) years. We asked them to name as many animals as they could. Analysis of variance was performed to determine the effect of demographic variables. No significant effect of gender was observed for any of the measures. However, age seemed to influence the number of category changes, as expected for a sensitive frontal measure, after being controlled for the effect of education. Educational level had a statistically significant effect on all measures, except for clustering. Subject performance (mean number of animals named) according to schooling was: illiterates, 12.1; 1 to 4 years, 12.3; 5 to 8 years, 14.0; 9 to 11 years, 16.7, and more than 11 years, 17.8. We observed a decrease in performance in these five educational groups over time (more items recalled during the first 15 s, followed by a progressive reduction until the fourth interval). We conclude that education had the greatest effect on the category fluency test in this Brazilian sample. Therefore, we must take care in evaluating performance in lower educational subjects.
