ABSTRACT

@#<p style="text-align: justify;"><strong>Objectives:</strong> Probiotic supplementation often only leads to transient improvement in the gut microbiome. Potential prebiotics, such as the oligosaccharide-rich varieties of Dioscorea esculenta tubers, can potentially bridge the gap between supplementation and persistent colonization. Thus, this study aimed to assess the ability of D. esculenta tubers to promote the growth of probiotic Lactobacillus sp. in vitro selectively.</p><p style="text-align: justify;"><strong>Methods:</strong> The prebiotic activity of the selected varieties of Dioscorea esculenta tubers was evaluated via compe titive growth assay, wherein the ratios of probiotic Lactobacillus sp. over enterotoxigenic Escherichia coli (ETEC) or "prebiotic ratios" were compared following treatment.</p><p style="text-align: justify;"><strong>Results:</strong> Negative control (0.9% NaCl solution) produced a ratio of 0.88, Lowland and Highland varieties produced ratios of 1.26 and 1.29, respectively, and positive control (inulin) produced 1.54. The two varieties had comparable ratios to one another (p > 0.05), and significantly higher ratios than the negative control (p < 0.05). Both varieties have significant prebiotic activity. Compared to inulin, the two varieties' prebiotic activity was 84% as effective.</p><p style="text-align: justify;"><strong>Conclusion:</strong> Overall, the tubers promoted the growth of Lactobacillus sp. over ETEC. The crude tuber samples, given their availability and affordability, can be easily integrated into the local diet to contribute to the improvement of the general population's health.</p>

ABSTRACT

As a type of prebiotics and dietary fiber, inulin performs plenty of significant physiological functions and is applied in food and pharmaceutical fields. Inulosucrase from microorganisms can use sucrose as the substrate to synthesize inulin possessing higher molecular weight than that from plants. In this work, a hypothetical gene coding inulosucrase was selected from the GenBank database. The catalytic domain was remained by N- and C- truncation strategies, constructing the recombinant plasmid. The recombinant plasmid was expressed in E. coli expression system, and after purifying the crude enzyme by Ni²⁺ affinity chromatography, a recombinant enzyme with a molecular weight of approximately 65 kDa was obtained. The optimal pH and temperature of the recombinant enzyme were 5.5 and 45 °C, respectively, when sucrose was used as the sole substrate. The activity of this enzyme was inhibited by various metal ions at different degrees. After purifying the produced polysaccharide, nuclear magnetic resonance analysis was used to determine that the polysaccharide was inulin connected by β-(2,1) linkages. Finally, the conditions for the production of inulin were optimized. The results showed that the inulin production reached the maximum, approximately 287 g/L after 7 h, when sucrose concentration and enzyme dosage were 700 g/L and 4 U/mL, respectively. The conversion rate from sucrose to inulin was approximately 41%.

ABSTRACT

Os cookies são alimentos práticos e convenientes e por isso vêm fazendo parte da alimentação diária dos consumidores. Neste trabalho foram desenvolvidas 5 formulações de café arábica com adição inulina em proporções variando de 0 a 100% e avaliadas suas características físicas e químicas. Todas as formulações apresentaram teor de umidade dentro do estabelecido pela legislação brasileira. Mesmo sendo padronizada a adição de lipídios nas formulações, houve diferença significativa entre as formulações, que variou de 5,97% a 24,10%. Este resultado mostrou que há uma correlação linear entre a adição de inulina e o teor de lipídios presente nas formulações. O mesmo não ocorreu no parâmetro cisalhamento, que variou de 23,75 N a 81,83 N. A não linearidade na taxa de cisalhamento dos cookies implica na interação dos diferentes componentes adicionados na formulação dos cookies. Assim, é possível o desenvolvimento de cookies de café com propriedades funcionais.

ABSTRACT

A dieta de cafeteria foi desenvolvida a fim de mimetizar a dieta ocidentalizada, uma vez que esta associa-se a desordens no perfil cardiovascular, como dislipidemias, hiperglicemia, acúmulo de gordura corporal, entre outros. Os frutanos tipo inulina (FTI) são fibras solúveis categorizados como prebióticos. O presente estudo objetivou avaliar os efeitos da dieta de cafeteria associadas aos FTI sobre o perfil cardiometabólico em ratos Wistar. Para tanto, utilizou-se 30 animais. Os FTI purificados, bem como, provenientes da matriz alimentar (yacon em pó), foram adicionados a seus respectivos grupos experimentais na dose de 6%, durante 30 dias. As variáveis analisadas foram: composição centesimal e conteúdo de FTI, ganho de peso (GP), peso relativo do ceco (PRC), peso relativo do fígado (PRF), consumo alimentar, glicemia, triglicerídeos, colesterol total, HDL-c, LDL-c, tecido adiposo subcutâneo e visceral (epididimal, retroperitoneal e mesentérica). Todas as análises seguiram os protocolos padronizados. A análise estatística foi realizada no software Sigma Stat 4.0 e teste de normalidade de Shapiro-Wilk, testes descritivos, ANOVA ou teste de Kruskal-Wallis seguidos dos testes de comparação de médias de Duncan ou Dunn's. O nível de significância adotado foi de p<0,05. A variável PRC foi estatisticamente maior nos grupos submetidos aos FTI. O grupo que recebeu dieta de cafeteria apresentou valores superiores no GP, VLDL, triglicerídeos, tecido adiposo subcutâneo e epididimal. Não houve diferença estatística nos parâmetros PRF, colesterol total, LDL-c, HDL-c e glicemia. Portanto, através deste trabalho, verificou-se efeitos sistêmicos benéficos dos FTI em parâmetros como: PRC, GP, VLDL, triglicerídeos, tecido adiposo(AU)


The cafeteria diet was developed in order to mimic the western diet, since it is associated with disorders in the cardiovascular profile, such as dyslipidemia, hyperglycemia, accumulation of body fat, among others. Inulin-type fructan (ITF) are soluble fibers categorized as prebiotics. The present study aimed to evaluate the effects of ITF associated with cafeteria diet on the cardiometabolic profile in Wistar rats. For this, 30 animals were used. The purified ITFs, as well as from the food matrix (yacon powder), were added to their respective experimental groups at a dose of 6% for 30 days. The analyzed variables were: centesimal composition and ITF content, weight gain (WG), relative weight of cecum (RWC), relative liver weight (RLW), dietary intake, glycemia, triglycerides, total cholesterol, HDL-c, LDL -c, subcutaneous and visceral adipose tissue (epididimal, retroperitoneal and mesenteric). All analyzes followed the standardized protocols. Statistical analysis was performed using the Sigma Stat 4.0 software and a Shapiro-Wilk normality test, descriptive tests, ANOVA or Kruskal-Wallis test followed by the Duncan or Dunn's averages comparison tests were performed. The level of significance was set at p <0.05. The RWC variable was statistically higher in the groups submitted to FTI. The group that received a cafeteria diet presented higher values in WG, VLDL, triglycerides, subcutaneous and epididimal adipose tissue. There was no statistical difference in the parameters RLW, total cholesterol, LDL-c, HDL-c and glycemia. Therefore, through this work, beneficial systemic effects of ITF were observed in parameters such as: RWC, WG, VLDL, triglycerides and adipose tissue(AU)

ABSTRACT

PURPOSE: The aim of this study was to identify the minimally meaningful dosage of inulin leading to a prebiotic effect in Indonesian infants. METHODS: In a randomized controlled double-blinded, parallel, 3-arm intervention study, 164 healthy formula-fed infants aged 3 to 5 months first obtained formula-A (without inulin) during a 4-week adaptation period. Subsequently, 142 subjects were subjected to a 4-week feeding period by administering either formula-A (no inulin), formula-B (0.2 g/100 mL inulin) or formula-C (0.4 g/100 mL inulin). The primary outcome parameter was %-bifidobacteria in faecal samples determined using quantitative polymerase chain reaction analyses. Secondary outcome parameters were faecal %-lactobacilli, pH and stool frequency, and consistency. Growth and tolerance/adverse effects were recorded as safety parameters. RESULTS: Typical %-bifidobacteria and %-lactobacilli at the end of the adaptation period in the study population were 14% and 2%, respectively. For faecal pH, significant differences between formula groups A vs. C and A vs. B were found at the end of the intervention period. Testing for differences in faecal %-bifidobacteria and %-lactobacilli between groups was hampered by non-normal data set distributions; no statistically significant differences were obtained. Comparisons within groups revealed that only in formula group C, all the three relevant parameters exhibited a significant effect with an increase in faecal %-bifidobacteria and %-lactobacilli and a decrease in pH. CONCLUSION: A consistent prebiotic effect along with a decrease in pH and increase in %-bifidobacteria and %-lactobacilli was found only in the group administered 0.4 g inulin/100 mL.

ABSTRACT

Inulin has been used as a prebiotic to alleviate glucose and lipid metabolism disorders in mice and humans by modulating the gut microbiota. However, the mechanism underlying the alleviation of metabolic disorders by inulin through interactions between the gut microbiota and host cells is unclear. We use ob/ob mice as a model to study the effect of inulin on the cecal microbiota by 16S rRNA gene amplicon sequencing and its interaction with host cells by transcriptomics. The inulin-supplemented diet improved glucose and lipid metabolism disorder parameters in ob/ob mice, alleviating fat accumulation and glucose intolerance. The α diversity of gut microbial community of ob/ob mice was reduced after inulin treatment, while the β diversity tended to return to the level of wild type mice. Interestingly, Prevotellaceae UCG 001 (family Prevotellaceae) was obviously enriched after inulin treatment. A comparative analysis of the gene expression profile showed that the cecal transcriptome was changed in leptin gene deficiency mice, whereas the inulin-supplemented diet partially reversed the changes in leptin gene-related signaling pathways, especially AMPK signaling pathway, where the levels of gene expression became comparable to those in wild type mice. Further analysis indicated that Prevotellaceae UCG 001 was positively correlated with the AMPK signaling pathway, which was negatively correlated with markers of glycolipid metabolism disorders. Our results suggest that the inulin-supplemented diet alleviates glucose and lipid metabolism disorders by partially restoring leptin related pathways mediated by gut microbiota.

ABSTRACT

Quark cheese is fresh cheese obtained by the coagulation of milk through the action mainly of lactic bacteria, resulting in fresh-flavor cheese with high acidity. A specific starter culture is used for its commercial production. However, in this work, this culture was replaced by kefir, a symbiotic system of lactic acid bacteria and yeasts, which is considered a probiotic product. Agave inulin is a soluble fiber regarded as prebiotic with the ability to improve the balance of the intestinal flora. The purpose of this work was to develop Quark cheese using kefir as a starter culture, with supplementation by agave inulin. Cheese was produced using 24-h fermentation at 25 ºC followed by drainage of the whey, with the addition of 3% inulin to the supplemented cheese. After whey drainage, the cheese was kept in plastic pots under refrigeration until analysis. Microbiological, pH and acidity parameters were analysed at 1, 7 and 14 days after manufacture. The results of the physical-chemical analyses remained close to those found in literature. The resulting cheese presented high counts of Lactobacilli indicating their probiotic potential. The addition of agave inulin decreased the amount of those microorganisms; however, they remained in high counts. It can be verified that the use of kefir in the production of Quark cheese is feasible, mainly in artisanal productions since it is usually inexpensive and easy to maintain, and the Lactobacilli remained stable during the storage period.(AU)


O queijo Quark é um queijo de massa fresca obtida por coagulação do leite pela ação principalmente de bactérias láticasobtendo-se um queijo de sabor refrescante, em sua produção comercial é empregada uma cultura starter específica para a produção de queijos, no presente trabalho essa cultura foi substituída pelo kefir, um sistema simbiótico de bactérias láticas e leveduras e que é considerado um produto probiótico. A inulina de agave é uma fibra solúvel considerada prebiótica com capacidade de melhorar o equilíbrio da flora intestinal. O objetivo desse trabalho foi desenvolver queijo Quark empregando kefir como cultura starter e suplementado com inulina de agave. Os queijos foram produzidos por fermentação durante 24h/25ºC seguido por drenagem do soro, no queijo suplementado com inulina foi adicionada 3%, após a dessoragem, os queijos foram mantidos em potes plásticos sob temperatura de refrigeração até o momento das análises, sendo que as microbiológicas, acidez e pH foram realizadas em 1, 7 e 14 dias após a fabricação. Os resultados das análises físico-químicas mantiveram-se próximos aqueles encontrados na literatura. Os queijos obtidos apresentaram altas contagens de Lactobacilli indicando potencial probiótico, a adição de inulina de agave diminuiu o número destes microrganismos, mesmo assim mantiveram-se em altas contagens. Pode-se constatar que o uso de kefir na produção de queijo Quark é viável, principalmente em produções artesanais uma vez que ele normalmente não possui custo e é de fácil manutenção e os Lactobacillimantiveram-se estáveis durante o período de armazenamento.(AU)


El queso Quark es un queso de masa fresca obtenido por coagulación de la leche y acción principalmente de bacterias lácticas, obteniendo un queso de sabor refrescante. En su producción comercial se utiliza un cultivo iniciador específico para producción de quesos, en el presente trabajo esa cultura fue reemplazada por kéfir, un sistema simbiótico de bacterias del ácido láctico y levaduras, que se considera un producto probiótico. La inulina de agave es una fibra soluble considerada prebiótica con la capacidad de mejorar el equilibrio de la flora intestinal. El objetivo de esa investigación ha sido desarrollar queso Quark, usando kéfir como cultivo inicial y complementado con inulina de agave. Los quesos se produjeron por fermentación durante 24h / 25ºC seguido de drenaje del suero, en el queso suplementado con inulina se añadió 3%, después del drenaje del suero y se mantuvieron en macetas de plástico a temperatura de refrigeración hasta el momento del análisis, siendo que las microbiológicas, el pH y la acidez se realizaron a los 1, 7 y 14 días después de la fabricación. Los resultados de los análisis fisicoquímicos se mantuvieron cerca de los encontrados en la literatura. Los quesos mostraron altos conteos de Lactobacilli indicando su potencial probiótico, la adición de inulina de agave disminuyó el número de estos microorganismos, sin embargo, permanecieron en conteos altos. Se puede verificar que el uso de kéfir en la producción de queso Quark es factible, principalmente en las producciones artesanales, ya que por lo general es económico y de fácil manutención. Los lactobacilos se han mantenido estables durante el período de almacenamiento.(AU)

ABSTRACT

Abstract Soymilk was produced from vegetable soybean and fermented by probiotics (Lactobacillus acidophilus La-5, Bifidobacterium animalis Bb-12) in co-culture with Streptococcus thermophilus. The composition of the fermented beverage and oligosaccharides content were determined. The effect of fructooligosaccharides and inulin on the fermentation time and viability of probiotic microorganisms throughout 28 days of storage at 5 °C were evaluated. The soymilk from vegetable soybeans was fermented in just 3.2 h, when pH reached 4.8. Fermentation reduced the contents of stachyose and raffinose in soymilk. Prebiotics had no effect on acidification rate and on viability of B. animalis and S. thermophilus in the fermented beverage. The viable counts of B. animalis Bb-12 remained above 108 CFU mL-1 in the fermented soymilk during 28 days of storage at 5 °C while L. acidophilus La-5 was decreased by 1 log CFU mL-1. The fermented soymilk from vegetable soybeans showed to be a good food matrix to deliver probiotic bacteria, as well as a soy product with a lower content of non-digestible oligosaccharides.

ABSTRACT

A avaliação da função renal é de extrema importância na prática clínica, tanto para o diagnóstico quanto para e prognóstico e monitoração das doenças renais. Neste contexto, aparticipação do laboratório é de grande importância, uma vez que a maior parte das doenças renais só se manifesta clinicamente quando mais de 50% a 75% da função renal estácomprometida. O desenvolvimento de novos biomarcadores para diagnóstico precoce, estratificação de risco, prognóstico de lesão renal tem sido um dos principais alvos das pesquisas envolvendo o sistema renal. Dessa forma, diversos novos biomarcadores, tais como lipocalina associada à gelatinase de neutrófilos (NGAL), cistatina C, molécula-1 de lesão renal (KIM-1), interleucina-18 (IL-18), enzimas urinárias tubulares e proteínas de baixo peso molecular, dentre outros, têm sido propostos para diagnosticar /monitorar as doenças renais agudas e crônicas. Este estudo visa discutir aspectos associados aos principais biomarcadores utilizados na rotina laboratorial para diagnóstico, prognóstico e acompanhamento do paciente com disfunção renal, bem como apresentar novos marcadores que se destacam na literatura recente e que podem ser promissores na prática clínica


The assessment of renal function is very important in clinical practice, both for diagnosis and for prognosis and monitoring of renal diseases. In this context, the role of the laboratory is of great importance, since most of the kidney disease manifests itself clinically only when more than 50 to 75% of kidney function is compromised. The development of new biomarkers for early diagnosis, risk stratification, prognosis of renal injury has been a major focus of research involving the renal system. Thus, several new biomarkers, such as neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), interleukin-18 (IL18) and low-molecular weight proteins and enzymes, and others, have been proposed to diagnose/monitoring acute and chronic renal diseases. The aim of this study is to discuss aspects related to the main biomarkers used in routine laboratory tests for diagnosis, prognosis and monitoring of patients with renal dysfunction, as well as provide new markers that stand out in the recent literature, and that may be promising in clinical practice

ABSTRACT

Os frutanos do tipo inulina são oligossacarídeos que favorecem a multiplicação de determinados gêneros bacterianos no intestino, promovendo um efeito prebiótico. Este trabalho avaliou o efeito da inulina extraída de raízes de yacon (Smallanthus sonchifolius) sobre a colonização intestinal de frangos de corte experimentalmente infectados por Salmonella Enteritidis. Sessenta frangos de corte com um dia de idade foram divididos em três grupos de tratamento, com duas repetições, criados até 21 dias. As aves do grupo yacon receberam 100mg de inulina/dia, via oral, por três dias consecutivos. No sétimo dia de vida, as aves tratadas e o controle positivo foram desafiados pela via oral com uma cultura de S. Enteritidis. Não foram observadas diferenças de desempenho zootécnico entre os grupos. O índice de infectividade das aves suplementadas com yacon foi menor até o sexto dia após o desafio, mas, ao término do experimento, foi superior ao controle positivo. Os dados deste trabalho demonstram que o uso da inulina nos três primeiros dias de vida promoveu uma redução da colonização intestinal dos frangos por Salmonella Enteritidis na primeira semana após o desafio. Novos estudos são necessários para determinar a dose e o tempo de tratamento ideal para um efeito protetor de maior duração.(AU)


The fructan inulin-type oligosaccharides favor the multiplication of some bacterial genera in the intestine, promoting a prebiotic effect. This study evaluated the effect of inulin extracted from yacon roots (Smallanthus sonchifolius) on intestinal colonization of broilers experimentally infected with Salmonella Enteritidis. Sixty-one day old chicks were grouped into three treatments, with two replicates, and reared until 21 days. Birds in the yacon group received 100mg of inulin/day orally for three consecutive days. On the seventh day of life the treated birds and the positive control were challenged orally with a culture of S. Enteritidis. There were no differences between groups in live performance. The infectivity index of the chicks supplemented with yacon was lower until the sixth day after the challenge, but at the end of the experiment it was higher than the positive control. Data from this study show that the use of inulin during the first 3 days of life caused a reduction of intestinal colonization of chickens by Salmonella Enteritidis in the first week after challenge. Further studies are needed to determine the dose and the ideal time of treatment necessary for a longer protective effect.(AU)

ABSTRACT

Objective: To evaluate the influence of the CO2 pneumoperitoneum in the glomerular filtration in a rat model with a 2/3 reduction of renal parenchyma. Methods: Adult Wistar male rats (n = 50) were subjected to right nephrectomy and a 2/3 ligature of the renal left vascular branch. Animals were randomly distributed as follows: GI (n = 10) - simulated, GII (n = 20) ­ 8 mm Hg pneumoperitoneum, and GIII (n = 20) ­ 15 mm Hg pneumoperitoneum. After two (GIIA and GIIIA) and three (GIIB and GIIIB) hours of insufflation, and one hour of disinsufflation, they were evaluated for the following aspects: mean blood pressure (MBP), microhematocrit, urinary volume and inulin clearance. Results: The microscopic aspects showed signs of glomerulosclerosis that caused proteinuria. Renal function with 8 mm Hg pneumoperitoneum after two hours of disinsufflation ( % = 202.68) was better than after three hours ( % = 10.89). With 15 mm Hg pneumoperitoneum, the renal function was damaged by both procedures, that is, two ( % = -3.57) and three hours ( % = -3.25). Conclusion: Inulin clearance evidenced renal insufficiency in the model with a 2/3 reduction of renal mass, and depending on both the increase of the exposure time and the pressure intensity, it can be more intensified.


Este estudo tem como objetivo avaliar a influência do pneumoperitônio induzido CO2 sobre a função renal em um modelo em ratos com redução de 2/3 de sua massa renal. Em relação à metodologia, ratos Wistar (n=50), machos, adultos, foram submetidos à nefrectomia direita e ligadura de 2/3 do pedículo vascular renal esquerdo. A seguir, foram aleatoriamente distribuídos em GI (n=10)­ Simulado, GII (n=20) com pneumoperitônio de 8 mmHg e GIII (n=20) compneumoperitônio de 15 mmHg, por uma hora. Após duas (GIIA e GIIIA) e três (GIIB e GIIIB) horas da desinsuflação, foram avaliadas a pressão arterial média (PAM), micro -hematócrito, volume urinário e clearance da inulina. Os resultados da microscopia mostraram que o rim remanescente apresentou sinais de glomeruloesclerose, caracterizada pela proteinúria. A função renal com pneumoperitônio de 8 mmHg após duas horas da insuflação ( %=202,68) foi melhor do que com três horas ( %= 10,89). Com o pneumoperitônio de 15 mmHg tanto com duas ( %=-3,57) quanto três horas ( %=-3,25), a função renal esteve prejudicada. Concluiu -se que oclearance da inulina mostrou haver um comprometimento da função renal no modelo de redução de 2/3 do parênquima e que, dependendo do volume e do tempo de pneumoperitônio, pode ser agravada.

ABSTRACT

The objective of this work was to adapt a synbiotic aerated diet dessert, produced with the addition of a probiotic culture of Lactobacillus acidophilus La-5 and prebiotic ingredients (fructooligosaccharides and inulin), from the previously developed sucrose-containing formulation, and to evaluate the effects of its ingestion on adult volunteers with metabolic syndrome (MetS) during a period of 8 weeks of intervention. In addition, to improve the resistance of the probiotic to simulated gastrointestinal conditions, a microencapsulation process was optimized. For the development of the product, the formulations were produced in triplicates, in which probiotic culture survival, instrumental texture and sensory acceptability were evaluated up to 112 days of storage under freezing (-18 °C). Subsequently, a randomized, double-blind, placebo-controlled trial was carried out in which the product developed was administered to forty-five volunteers with MetS assigned into two groups, each receiving 40 g/day of: synbiotic diet mousse (SDM) (n=23) and placebo diet mousse (PDM) without pro- and prebiotics (n=22). Fasting blood samples were collected at the beginning and after 8 weeks of daily consumption of both mousses to determine the anthropometric, biochemical, haematological, inflammatory, and immunological parameters. Afterward, with the goal of improving the survival of L. acidophilus La-5 to in vitro simulated gastrointestinal conditions, the microencapsulation process conditions of the probiotic strain via spray drying were optimized using inulin as the encapsulating agent. The viability of L. acidophilus La-5 incorporated into SDM was above 7.8 log CFU/g and remained stable throughout storage. PDM showed lower acceptability (5.77-6.50) after storage than SDM (6.67-7.03). The texture was the most appreciated attribute and hardness of the SDM increased during storage, but remained stable for PDM. The clinical trial revealed significant reductions of total cholesterol and HDL-cholesterol, as well as of immunoglobulins (A and M), and interleukin-1ß in both groups during the intervention period. However, regarding intergroup changes, there were not any significant differences for all parameters evaluated (p>0.05). After the optimization of the microencapsulation process of the probiotic culture (80 mL/min, 82% and 10%, respectively for feed flow, aspiration rate, and inulin concentration), the microencapsulated probiotic strain incorporated in the SDM mousse showed the highest in vitro gastrointestinal survival (p<0.05) in the different stages of the assay, as follows: after the gastric phase: 5.68 log CFU/g (83.3%), the enteral phase I: 5.61 log CFU/g (82.3%), the enteral phase II: 5.56 log CFU/g (81.4%). Therefore, these results suggest that the presence of probiotic and prebiotics in SDM did not provide an additional effect on the health of volunteers with MetS. Additionally, the results confirm the appropriateness of the spray drying process to microencapsulate L. acidophilus La-5 using inulin as coating agent, providing increased resistance to the microencapsulated probiotic strain under in vitro gastrointestinal stress


O objetivo deste trabalho foi adaptar uma sobremesa aerada simbiótica diet do tipo musse, processada com a adição de uma cultura probiótica de Lactobacillus acidophilus La-5 e de ingredientes prebióticos (fruto-oligossacarídeos e inulina), a partir da formulação contendo sacarose desenvolvida anteriormente, e avaliar os efeitos de sua ingestão em voluntários adultos com síndrome metabólica (MetS) durante um período de 8 semanas de intervenção. Adicionalmente, para melhorar a resistência do probiótico frente às condições gastrintestinais simuladas, otimizou-se um processo de microencapsulação da cepa probiótica. Para o desenvolvimento do produto, as formulações foram produzidas em triplicata, em que se avaliou a sobrevivência da cultura probiótica, a textura instrumental e a aceitabilidade sensorial até 112 dias de armazenamento sob congelamento (-18 oC). Em seguida, foi realizado um estudo randomizado, duplo-cego e controlado por placebo, no qual o produto desenvolvido foi administrado a quarenta e cinco indivíduos com MetS divididos em dois grupos, cada um recebendo 40 g/dia de: mousse simbiótica diet (SDM) (n=23) e musse placebo diet (PDM) sem componentes pro- e prebióticos (n=22). As amostras sanguíneas foram coletadas em jejum no início e após 8 semanas de consumo diário de ambas as musses para a determinação dos parâmetros antropométricos, bioquímicos, hematológicos, inflamatórios e imunológicos. Posteriormente, com o intuito de melhorar a sobrevivência do L. acidophilus La-5 em condições gastrointestinais simuladas in vitro, as condições de processo de microencapsulação da cepa probiótica via spray drying foram otimizadas, utilizando inulina como agente encapsulante. A viabilidade de L. acidophilus La-5 incorporados na SDM foi superior a 7,8 log UFC/g e se manteve estável ao longo do armazenamento. A PDM mostrou menor aceitabilidade (5.77-6.50) após o armazenamento do que a SDM (6.67-7.03). A textura foi o atributo mais apreciado, sendo que a dureza da SDM apresentou elevação, enquanto a da PDM manteve-se estável. O ensaio clínico revelou reduções significativas de colesterol total, colesterol-HDL, imunoglobulinas (A e M) e interleucina1ß em ambos os grupos durante o período de intervenção. Entretanto, no que se refere às mudanças intergrupos, não se observou diferenças significativas para todos os parâmetros avaliados (p>0,05). Após a otimização do processo de microencapsulação da cultura probiótica (80 mL/min, 82% e 10%, respectivamente para o fluxo de alimentação, taxa de aspiração e concentração de inulina), a cepa probiótica microencapsulada incorporada a amostra SDM apresentou a maior sobrevivência gastrointestinal in vitro (p<0,05) nas diferentes etapas do ensaio, a saber: após a fase gástrica: 5,68 log UFC/g (83,3%); fase entérica I: 5,61 log UFC/g (82,3%); fase entérica II: 5,56 log UFC/g (81,4%). Portanto, esses resultados sugerem que a presença de probiótico e prebiótico na SDM não apresentou efeitos adicionais na saúde dos voluntários com MetS. Adicionalmente, os resultados confirmaram a adequação do processo de spray drying para a microencapsulação de L. acidophilus La-5 utilizando inulina como agente de revestimento, proporcionando uma maior resistência da cepa probiótica microencapsulada às condições gastrintestinais simuladas in vitro.

ABSTRACT

O objetivo do trabalho foi verificar a aceitabilidade sensorial de barras de cereais adicionadas de inulina entre praticantes de lutas marciais. Também, determinar a composição físico-química da formulação padrão e daquela com maior teor de inulina e aceitação semelhante à padrão. Foram elaboradas cinco formulações de barras de cereais: F1 (padrão, com 0% de inulina) e as demais contendo 2% (F2), 4% (F3), 6% (F4) e 8% (F5) de inulina. Participaram da avaliação sensorial 100 provadores não treinados, de ambos os gêneros, com idade entre 18 e 60 anos. Na análise físico-química foram avaliados os teores de umidade, cinzas, proteínas, lipídios, carboidratos, calorias e fibra alimentar. Não houve diferença significativa (p>0,05) entre as amostras para os atributos aparência, aroma e cor. Contudo, F5 apresentou menor aceitabilidade que a formulação padrão nos atributos sabor e textura, bem como aceitação global e intenção de compra. Considerando esse contexto, F4 foi a amostra com maior teor de inulina e aceitação similar à padrão na maioria dos atributos avaliados, sendo selecionada juntamente com a formulação padrão para avaliação da composição físico-química. Não houve diferença entre os teores de umidade, cinzas, proteínas e lipídios para a formulação padrão e F4. Menores conteúdos de calorias e maiores de carboidratos e fibra alimentar foram verificados em F4 comparando-se com a amostra padrão. Conclui-se que um nível de adição de até 6% de inulina em barras de cereais foi bem aceito pelos provadores, obtendo-se aceitação sensorial semelhante ao produto padrão e com boas expectativas de comercialização


The objective this study was to verify the sensory acceptability of cereal bars added inulin between practitioners of martial arts. Also, to determine the physico-chemical composition of the standard formulation and that more inulin content and standard similar to acceptance. Five formulations were prepared cereal bars: F1 (standard with 0% inulin) and the other containing 2% (F2), 4% (F3), 6% (F4) and 8% (F5) inulin. Participated in the sensory evaluation 100 untrained panelists, of both genders, aged between 18 and 60 years. The physico-chemical analysis evaluated the moisture, ash, protein, lipids, carbohydrates, calories and dietary fiber content. There was no significant difference (p>0.05) between samples for appearance, aroma and color attributes. However, F5 had lower acceptability than the standard formulation in taste and texture attributes, and global acceptance and purchase intent. Considering this context, F4 was the sample with the highest inulin content and similar acceptance to the standard in most of the evaluated attributes being selected along with the standard formulation for evaluation of physico-chemical composition. There was no difference between the moisture, ash, protein and lipids content to the standard formulation and F4. Lower content of calories and higher carbohydrate and dietary fiber were found in F4 comparing it with the standard sample. It is concluded that a level of addition of up to 6% inulin into the cereal bars was well accepted by tasters to give sensory acceptance similar to standard product with good market expectation

ABSTRACT

Jerusalem artichoke (JA) mainly consists of inulin. In many experimental studies, inulin has been shown to be beneficial for decreasing glucose level. Therefore, JA is lately attracting wide attention as an anti-diabetic food. Therefore, many patients ingest JA in extract form. However, there are no published clinical studies in patients with diabetes to demonstrate benefit from the use of inulin-type fructans. We experienced a diabetes inpatient with acute hyperglycemia associated with JA. We could not control the patient's blood glucose in spite of addition and increment of insulin. We found that she had taken extracts of JA and recommended cessation. After discontinuing JA extracts, her blood glucose was well controlled in spite of discontinuation of insulin. Thus, in this patient, JA had actually increased blood glucose. We suggest that JA may be dangerous for use in diabetic patients.

ABSTRACT

Pombalia calceolaria L., Violaceae, popularmente conhecida por ipeca-da-praia, ipecabranca, ipecacunha dos raizeiros é uma Pombalia calceolaria L., Violacea e, popularmente conhecida por ipeca-da-praia, ipecabranca, ipecacunha dos raizeiros é uma herbácea perene, predominante no sertão nordestino. Embora não existam dados na literatura comprovando sua atividade farmacológica, pordécadas, suas raízes são preparadas na forma de decocto, lambedor e maceração, cujas principais indicações populares são para tosse, expectoração, como vermífugo, antidiarréico epara dentição. O presente estudo teve por objetivo realizar a caracterização farmacognósticadas raízes de P. calceolaria nos aspectos botânicos, químicos e farmacológicos. Aimportância da caracterização morfoanatômica está no fato de que não há registro em literatura descrevendo o perfil botânico desta espécie vegetal. Assim, as raízes recém coletadas de P. calceolaria foram caracterizadas morfologicamente com vista desarmada e em seguida realizada a caracterização anatômica através de secção histológica, reação histoquímica, registro fotomicrográfico em campo de luz claro, onde foi evidenciado que araiz em estudo apresenta o xilema secundário oriundo do câmbio com dimorfismo no tamanho dos vasos e floema secundário constituído de poucas camadas circundando o xilema. Noparênquima cortical foi visualizado e fotomicrografado, sob luz polarizada, a presença decristais de inulina...


Early diagnosis of HIV in Brazil still represents a challenge. It is estimated that about 30% of people living with HIV do not know their HIV status. 43% of the population comes to health services with late diagnosis in clinical conditions as AIDS-related. In this scenario, female sex workers - SW, are considered the most vulnerable, with HIV prevalence rate of 4.8%, while among women in the general population, the prevalence is 0.4%. Thus, the aim of this work was to understand what incentives and barriers that involve performing diagnostic testing of HIV among female sex workers in the city of Fortaleza, Ceará. It built an analysis of their realities which tried to contribute to the reduction of vulnerabilities associated with HIV/AIDS infection. We used a qualitative approach using the methodology "Rapid Assessment" (RA) from the anthropological presuppositions. We conducted interviews with 36 SW women, field observation, and document analysis. The decision to perform an HIV test is determined by the intersection of individual, social, programmatic factors, linked to social inequalities. The disconnection between common sense and scientific knowledge, linked to the influence of religious beliefs, constituted as a barrier to testing. The prenatal was configured as a process that enables the test but does not encourage its regularity in nonpregnant time. Most respondents spoke of continued use of condom with their clients, however, do not use it with their steady partners. Women often want to do the test, however the main barrier is the difficulty of access to services. The integration of the populations most vulnerable to HIV in health care depends on the mode of organization of the health system. It is necessary to consider their demands and needs, strategically and collectively with their

ABSTRACT

BACKGROUND/AIMS: Race and ethnicity are important determinants when estimatingglomerular filtration rate (GFR). The Korean coefficients for the isotope dilution mass spectrometry (IDMS) Modification of Diet in Renal Disease (MDRD) Study equations were developed in 2010. However, the coefficients have not been validated. The aim of this study was to validate the performance of the Korean coefficients for the IDMS MDRD Study equations. METHODS: Equation development and validation were performed in separate groups (development group, n = 147 from 2008 to 2009; validation group, n = 125 from 2010 to 2012). We compared the performance of the original IDMS MDRD equations and modified equations with Korean coefficients. Performance was assessed by comparing correlation coefficients, bias, and accuracy between estimated GFR and measured GFR, with systemic inulin clearance using a single injection method. RESULTS: The Korean coefficients for the IDMS MDRD equations developed previously showed good performance in the validation group. The new Korean coefficients for the four- and six-variable IDMS MDRD equations using both the development and validation cohorts were 1.02046 and 0.97300, respectively. No significant difference was detected for the new Korean coefficients, in terms of estimating GFR, between the original and modified IDMS MDRD Study equations. CONCLUSIONS: The modified equations with Korean coefficients for the IDMS MDRD Study equations were not superior to the original equations for estimating GFR. Therefore, we recommend using the original IDMS MDRD Study equation without ethnic adjustment in the Korean population.

ABSTRACT

La guayaba (Psidium guajava L.) es una fruta de gran aceptación que puede ser utilizada como vehículo de nutrientes y componentes bioactivos, cualidades atractivas para elaborar alimentos con beneficios a la salud. Por tal motivo, se desarrollaron laminados de guayaba enriquecidos con inulina y calcio. Para elaborar los laminados se preparó un puré con pulpa de guayaba, sacarosa y fructosa en proporción 85:10:5, se adicionó inulina, lactato de calcio, solución de ácido cítrico (30%) y se deshidrató en un secador de bandejas a 60 ºC. Se desarrollaron cuatro formulaciones variando las proporciones de inulina y lactato de calcio. Se evaluó la aceptabilidad global de los laminados con una escala hedónica no estructurada de 10 cm (cero representó “me disgusta mucho”, cinco “indiferente” y diez “me gusta mucho”) y la aceptabilidad de los atributos sensoriales dulzor, acidez, color y dureza al morder con una escala JAR (just-about-right) de 3 puntos. Se evaluaron las características físicas, químicas y nutricionales de los laminados elaborados bajo la formulación seleccionada sensorialmente. La aceptabilidad varió entre 6,6 y 7,2, donde los laminados elaborados con 1,0 g de inulina y 1,0 g de lactato de calcio/100g de pulpa representaron la mejor opción. El producto presentó bajo dulzor, alta acidez y alta dureza al morder, sin embargo, ninguno de los atributos causó desagrado. Los laminados de guayaba aportan calcio y fibra dietaria a la ingesta diaria y representan una opción innovadora con potencial de alimento funcional, útil para diversificar y motivar el consumo de frutas y derivados(AU)


Guava (Psidium guajava L.) laminates enriched with inulin and calcium. Guava (Psidium guajava L.) is a fruit of great acceptance that can be used as vehicle of nutrients and bioactive components, attractive qualities for making products with health benefits. Therefore, guava laminates enriched with inulin and calcium were developed. To elaborate the laminates a puree was prepared with guava pulp, sucrose and fructose in proportion 85:10:5, inulin, calcium lactate and citric acid solution (30%) was added and it was subjected to drying in a tray dehydrator at 60 °C. Four formulations were developed varying the proportions of inulin and calcium lactate. The overall acceptability of laminates was evaluated wih a 10-cm unstructured hedonic scale (zero represented "I dislike much" five "indifferent" and ten "I like") and the acceptability of the sensory attributes sweetness, acidity, color and hardness to bite with a 3-point JAR (just-about-right) scale. Physical, chemical and nutritional characteristics of the laminates produced under the selected treatment were evaluated. Acceptability varied between 6.6 and 7.2, where laminates made with 1.0 g inulin and 1.0 g calcium lactate/ 100g pulp represented the best choice. The product presented low sweetness, high acidity and high hardness to bite, however, none of the attributes caused displeasure. Guava laminates provide calcium and dietary fiber daily intake and represent an innovative option with potential functional food, useful to diversify and encourage consumption of fruits and derivatives(AU)
