    Full Text Available Populações duplo-haplóides apresentam especial vantagem para análises genéticas, uma vez que a informação que elas oferecem pode ser maximizada, devido ao fato que todos os locos encontram-se em homozigose. O objetivo deste trabalho foi o desenvolvimento de duas populações duplo-haplóides (DHs de cevada (Hordeum vulgare ssp. vulgare L. segregantes para a atividade das enzimas (1-3, 1-4-β-glucanases, através da técnica de cultura de anteras. Foram realizados dois cruzamentos com cultivares contrastantes para esta característica. As cultivares parentais selecionadas foram 'MN 698' e 'CEV 97047', para o desenvolvimento da população "malte verde" (MV, e 'Embrapa 127' e 'CEV 96025' para o desenvolvimento da população "malte seco" (MS. Foram cultivadas 10.734 anteras da população MS e 4.139 anteras da população MV. A população MV produziu 50% mais plântulas verdes quando comparada à população MS, refletindo a importância do genótipo na resposta à cultura de anteras e na regeneração. A maioria das plantas adultas duplo-haplóides foi obtida através da duplicação espontânea in vitro do genoma haplóide, ocorrendo em 66% das plantas da população MS e 76% das plantas da população MV. Também foram observadas, em menor frequência, plantas haplóides, triplóides e tetraplóides. Através da técnica de cultura de anteras, foram desenvolvidas 204 linhagens duplo-haplóides, das quais 72 linhagens são da população "malte seco" e 132 linhagens são da população "malte verde". Este material constitui um importante germoplasma para o melhoramento genético da cevada.Doubled haploid populations offer special advantages in genetic analyses, since the information they provide may be maximized due to the fact that all loci are homozygous. The aim of this study was to develop two barley (Hordeum vulgare ssp.vulgare L. doubled-haploid (DHs populations segregating to (1-3, 1-4-β-glucanases activity, utilizing the anther

    Full Text Available O objetivo deste trabalho foi avaliar o impacto da antecipação da colheita de lavouras de cevada sobre a germinação dos grãos, ao longo de 12 meses de armazenamento. O ensaio de campo foi realizado em 2002 e 2003. As parcelas colhidas foram armazenadas nos anos subseqüentes aos dos ensaios em campo, e a germinação foi monitorada mensalmente. Os tratamentos avaliados foram: dessecação com os princípios ativos glifosato e paraquat, nas doses 1, 1,5 e 2 L ha-1, além das testemunhas, colhidas normalmente e de forma antecipada, sem dessecação. O delineamento utilizado foi o de blocos ao acaso, com três repetições. A colheita antecipada sem dessecação foi o tratamento de maior prejuízo qualitativo à germinação dos grãos. A deterioração qualitativa temporal dos grãos, nos tratamentos com herbicidas dessecantes, foi estatisticamente similar à observada nas amostras oriundas da testemunha colhida normalmente, sem dessecação. Não foram encontradas evidências de que o uso de herbicidas dessecantes acelere o processo de perda de germinação de grãos de cevada, ao longo do período de armazenagem, para os produtos e doses testados.The objective of this work was to assess the impact of early harvesting of barley on grain germination, along 12 months of storage. A field trial was carried out in 2002 and 2003. The plot yields were stored during the years subsequent to the field trial, and germination was monitored monthly. The following treatments were evaluated: desiccation with glyphosate and paraquat, at 1, 1.5, and 2 L ha-1, and the checks, which were normal and early harvest without desiccation. A randomized block design with three replications was utilized. The early harvest without desiccation treatment had the greatest quality loss regarding grain germination. Qualitative deterioration of grains within time was statistically similar both in treatments with desiccation and those with normal harvest without desiccation

    Full Text Available Áreas com diferentes potenciais de rendimento dentro de uma lavoura necessitam ser manejadas separadamente, para fins de aplicação da adubação nitrogenada em cobertura. O equipamento baseado em sensoriamento remoto terrestre (GreenSeeker é um dos instrumentos utilizados para separar diferentes zonas de manejo. Para fazer isso, o sensor permite a definição de classes para estimar o potencial produtivo de forma ágil, precisa e em tempo real. Com o instrumento, foi desenvolvido um modelo para estimativa do potencial produtivo em trigo e cevada, correlacionando o Índice de Vegetação por Diferença Normalizada (NDVI com a biomassa seca acumulada na parte aérea, por ocasião da emissão da sexta folha do colmo principal. A base do modelo foi a formação de classes de potencial produtivo correspondentes a zonas específicas de manejo da lavoura. Essas classes não necessitam ser específicas para diferentes cultivares e/ou espécies, visto que não se detectaram diferenças que justificassem a formação de grupos para elas. As superfícies de fundo (resíduos de restevas de soja e milho tiveram efeitos significativos nas leituras do sensor. O modelo continua válido mesmo se as leituras de NDVI forem feitas antes ou após o período recomendado para tal, podendo ser ajustado com sub ou superestimação. As análises de variabilidade espacial, futuramente, podem avaliar se, as zonas de potencial produtivo estimadas pelas classes de NDVI propostas pelo modelo, correspondem à flutuação espacial da biomassa, doses de N aplicadas e rendimento de grãos.Areas with different yield potential within a field need to be managed separately as for nitrogen application in small grain cereals. Terrestrial remote sensing-based equipment such as the GreenSeeker sensor is one of the tools available to handle different management zones. To do this, the sensor allows the definition of classes to estimate yield potential. A model which correlated the

    Cereais são geralmente processados com o objetivo de produzir produtos aceitáveis ao consumidor. O perolamento é utilizado para remover as casca aderidas ao grão de cevada bem como o gérmem para assim aumentar o tempo de prateleira do grão e seus produtos. O objetivo deste trabalho foi avaliar a atividade antioxidante de duas variedades de cevada (nua e vestida e relacionar esta atividade com a composição fenólica. Os grãos de cevada foram perolados e as frações obtidas foram analisadas in vitro utilizando os métodos de atividade antioxidante (Método do Radical Livre DPPH e Análise ORAC e determinação dos compostos fenólicos (Método de Folin-Ciocalteau e CLAE. A atividade antioxidante em ambos métodos apresentou um decréscimo significante após o primeiro minuto do perolamento e os resultados apresentaram direta correlação com a composição fenólica. Este perfil é observado gradualmente nas amostras, até o terceiro minuto do perolamento. Faz-se necessário que o processamento de cevada seja optimizado com o objetivo de reduzir a perda destes compostos durante o fracionamento.

    Full Text Available Approximately 8% of all non-Hodgkin lymphomas are extranodal marginal zone B cell lymphoma of mucosa associated lymphoid tissue (MALT, also known as MALT lymphoma, which was first described in 1983 by Isaacson and Wright. MALT lymphomas arise at a wide range of different extranodal sites, with the highest frequency in the stomach, followed by lung, ocular adnexa, and thyroid, and with a low percentage in the small intestine. Interestingly, at least 3 different, apparently site-specific, chromosomal translocations and missense and frameshift mutations, all pathway-related genes affecting the NF-κB signal, have been implicated in the development and progression of MALT lymphoma. However, these genetic abnormalities alone are not sufficient for malignant transformation. There is now increasing evidence suggesting that the oncogenic product of translocation cooperates with immunological stimulation in oncogenesis, that is, the association with chronic bacterial infection or autoaggressive process. This review mainly discusses MALT lymphomas in terms of their genetic aberration and association with chronic infections and summarizes recent advances in their molecular pathogenesis.

    1987-11-01

    Heat pumps have halved the energy costs of producing finished malt at two of the country's maltsters. The fuel-fired kilning processes described are now performed by heat pumps with considerable energy and production benefits at the maltings of J.P. Simpson and Co. (Alnwick) Ltd, in Tivetshall St Margaret, Norfolk, and of Munton and Fison Plc of Stowmarket, Suffolk. The heat pump system installed at the Station Malting of J.P. Simpson was devised by the Electricity Council Research Centre at Capenhurst near Chester. Energy cost benefits of Pound 6,000 a month are being realised at Simpsons, but there is the added benefit that the system has been designed to provide conditioned air to the germination cycle to ensure that the correct temperature is maintained throughout the year. At the Cedars factory of Munton and Fison, heat pumps were used on a trial basis for plant micropropagation and for a fish farming unit.

    Full Text Available In this work the α and β-amylase enzymes were obtained from maize (Zea mays malt and were biochemistry characterized. A germination study to obtain the maize malt with good amylase activity was made. The maize seeds were germinated in laboratory and the enzymatic activity was measured daily. Activity dependence to germination time were fitted to an exponential model (A=A0eµt, which showed that the behaviour of enzymatic activity in the germination process was similar to the growth of the microorganism. Its model could be applied to describe the mechanism of α-amylase production for each maize varieties and others cereals. Maize malt characterization showed that α and β-amylase had optimal pH between 4-6.5, optimal temperature 50 and 90ºC, and molecular weight of 67.4 and 47.5kDa, respectively. This work contributed with the advances in biotechnology generating of conditions for application of a new and of low price amylases source.Neste trabalho as enzimas α e β-amilases foram obtidas de malte de milho e depois foram caracterizadas bioquimicamente. Um estudo da germinação foi feito para obtenção do malte com boa atividade amilásica. A germinação ocorreu em escala laboratorial e a atividade enzimática foi medida diariamente. Um modelo exponencial do tipo A=A0eµt foi ajustado a dependência do tempo de germinação com a atividade, mostrando que o comportamento da atividade enzimática no processo de germinação é semelhante ao crescimento de microorganismos. Este modelo pode ser aplicado para descrever o mecanismo de produção da α-amilase para cada variedade de milho e de outros cereais. A caracterização do malte de milho mostrou que as α e β-amilase têm pH ótimo entre 4,0-6,5, temperatura ótima de 50 e 90ºC, e massa molar de 67,4 e 47,5 kDa, respectivamente. Este trabalho contribuiu com os avanços da biotecnologia gerando condições de emprego de uma nova e barata fonte de amilases.

Os tratamentos de calagem (parcelas e as doses de gesso (subparcelas foram aplicados na instalação do sistema plantio direto, em 1998. Avaliaram-se as alterações nos atributos químicos do solo e no crescimento de raízes de cevada no inverno de 1999, após o cultivo de soja. A calagem, na superfície ou incorporada e a aplicação de gesso não influenciaram significativamente o crescimento radicular da cevada, embora o gesso tenha proporcionado melhor distribuição relativa de raízes em profundidade, principalmente quando associado à calagem. Em condições de déficit hídrico severo, não houve limitação no crescimento radicular da cevada, em profundidade, para o teor de Ca trocável de 6 mmol c.dm-3 e a saturação por Al de 35%. A incorporação de calcário melhorou a nutrição de N e K da cevada, mas a produção não foi influenciada pela correção da acidez do solo por meio da calagem na superfície ou com incorporação, certamente devido à prolongada estiagem no período de florescimento da cultura, o que limitou a produção de grãos. A aplicação de gesso melhorou a absorção de N, P, K, Ca e S pela cevada, em condições de deficiência hídrica, proporcionando acréscimos na produção de grãos, em decorrência do aumento de Ca trocável, da relação Ca/Mg e do S-SO4(2- disponível no solo

    Malt is a preferred base for fermentations that produce beer or whisky. Barley for malt is grown under diverse environments in different geographical locations. Malt provides an ecological niche for a varied range of microorganisms with both positive and negative effects on its quality for brewing. Little information exists in the literature on the microbial community structure of Australian malt as well as broader global geographical differences in the associated fungal and bacterial communities. The aims of the present study were to compare the bacterial and fungal community structures of Australian commercial malt with its international counterparts originating from different geographical regions using terminal restriction fragment length polymorphism (TRFLP) fingerprinting and clone library analyses of ribosomal RNA genes. Further, the relationship between malt associated microbial communities and conventional malt quality parameters was also compared. Results showed that differences in fungal communities of malts from different geographical location were more pronounced than bacterial communities. TRFLP analysis discriminated high quality commercial malts with low fungal loads from malts deliberately infected with fungal inocula (Fusarium/Penicillium). Malt moisture, beta-amylase, α-amylase and limit dextrinase contents showed significant correlations with fungal community structure. This investigation concluded that fungal community structure was more important to subsequent malt quality outcomes than bacteria. PMID:26340674

  2. Primary ocular adnexal MALT lymphoma

    International Nuclear Information System (INIS)

    Described are the clinical and basic findings of B-cell lymphoma in ocular adnexal mucosa-associated lymphoid tissue (MALT), a rare and indolent disease with rather good prognosis, mainly on authors' retrospective examination. Subjects examined are 114 patients (71 M, 43 F; median age 57.5 y) from 1970 to 2003 in their hospital with the disease localized at stage I/II (107 cases, 94%) and at progression in both sides (17, 15%), and 100 cases (88%) of whom are defined in low risk group of the International Prognostic Index. The disease is sensitive to radiation and the initial treatment is done on about a half of patients (58 cases, 51%) with it, on 15 cases (13%) with chemotherapy alone, on 5 (4%) with chemo- and radio-therapy, and not done on 36 (32%). No significant difference in 10-year overall survival is seen among these treatment groups, but progression free survival tends to be higher in the group treated with radiation. Observed are no severe complication and 3 deaths by the disease progression. This MALT lymphoma is heterogeneous in cell genetics with various chromosome aberrations and in histopathology. Its relation with Chlamydia infection has been suggested. Radiation therapy is most widely applied, but observatory follow up without any treatment can be an option. (R.T.)

Foram utilizadas amostras de 17 cultivares, da Embrapa Trigo, Passo Fundo, RS, da safra de 2005. As determinações químicas foram realizadas de acordo com os métodos de análise oficial da AOAC Internacional. Foram observadas diferenças significativas entre grãos integrais de cultivares para proteína bruta, cinzas, extrato etéreo, fibra total e carboidratos não-fibrosos, porém, os teores de fibra insolúvel e fibra solúvel não diferiram. Em grãos descascados, foram observadas diferenças em todos os parâmetros analisados. Com exceção da fração de carboidratos não-fibrosos, o processo de descascamento promoveu redução em todas as frações avaliadas, em especial nos teores de fibra total e fibra insolúvel. Diferenças na composição bromatológica ocorreram devido à variabilidade genética das cultivares e ao descascamento.The objective of this work was to determine the chemical composition of different covered and hulness barley cultivars grains and to classify them according to distinctive nutritional groups. Seventeen cultivars from 2005 crop of Embrapa Trigo, Passo Fundo, RS, Brazil, were utilized. The chemical determinations were based on Official Methods of Analysis of the AOAC International. Significative differences between integral cultivars in relation to crude protein, ash, ether extract, total fiber and non-fibrous carbohydrate were observed, however, there were no differences for fiber content and soluble fiber. In the hulness grain, differences were observed. The non-fibrous carbohydrate was an exception and, in this case, the hull's process promoted the fraction's reduction, specially in the total fiber and insoluble fiber content.

    Full Text Available In this work, it was studied the hydrodynamic behavior of an expanded bed adsorption column to obtain the optimum conditions for amylase recovery from maize malt. Amberlite IRA 410 ion-exchange resin was used in chromatographic bed, phosphate buffer with and without 2% of maize malt and distiller water as fluidizers at temperatures of 295.15 ± 1 K and 301.15 ± 1 K. The results showed that the experimental data were fitted to the Richardson and Zack equation, and the comparison between the experimental and calculated terminal velocities demonstrated low relative error, minor than 15% from theoretical velocity values; it validates the use and application of these equations in expanded bed adsorption. The study of residence time distribution indicated that Daxial and Pe increased by reason of elevation of temperature, bed height and bed voidage. N had constant value of 2.14, being the best condition of amylase recovery that which represented low bed voidage, due to better economic viability.

    Full Text Available Malting quality of barley depends on genetic and agro-ekological factors. Chemical composition of malting barley and its technological parameters are very important for malting and brewing, due to this fact the quality of barley must be strictly evaluated. The aim of this work was to evaluate the influence of variety, locality and year of production on the 5 technological parameters of malt: extract, relative extract at 45 °C, Kolbach index, diastatic power and friability. It was found out that the barley variety significantly influenced the following parameters: extract, relative extract and diastatic power. The growing locality weakly influenced qualitative parameters i.e. Kolbach index and relative extract at 45°C. The study confirmed the most significant impact of the year on the Kolbach index and friability.

    MALT1 channels proximal T-cell receptor (TCR) signalling to downstream signalling pathways. With MALT1A and MALT1B two conserved splice variants exist and we demonstrate here that MALT1 alternative splicing supports optimal T-cell activation. Inclusion of exon7 in MALT1A facilitates the recruitment of TRAF6, which augments MALT1 scaffolding function, but not protease activity. Naive CD4+ T cells express almost exclusively MALT1B and MALT1A expression is induced by TCR stimulation. We identify...

    Seven years have passed since the start of MALT (Micro Analysis Laboratory, Tandem accelerator). An increasing emphasis has been placed, among others, on the accelerator mass spectroscopy (AMS), and also on proton-induced X-ray emission analysis (PIXE). The present paper describes major recent modifications of the system. A cesium sputter ion source dedicated to carbon 14 AMS was manufactured. The contamination of a source plasma chamber and electrodes decreases markedly, but still insufficient. As is increased ion currents injected to the accelerator, the electric field near the beam inlet section may be distorted, and thus deteriorate the beam transmission. (M. Tanaka)

    The brewing of beer involves two major biological systems, namely malted barley (malt) and yeast. Both malt and yeast show natural variation and assessing the impact of differing malts on yeast performance is important in the optimisation of the brewing process. Currently, the brewing industry uses well-established tests to assess malt quality, but these frequently fail to predict malt-associated problem fermentations, such as incomplete fermentations, premature yeast flocculation (PYF) and gushing of the final beer product. Antimicrobial compounds, and in particular antiyeast compounds in malt, may be one of the unknown and unmeasured malt factors leading to problem fermentations. In this study, the adaptation of antimicrobial assays for the determination of antiyeast activity in malt is described. Our adapted assay was able to detect differing antiyeast activities in nine malt samples. For this sample set, malts associated with PYF during fermentation and gushing activity in beer showed high antiyeast activity. Both PYF and gushing are malt quality issues associated with fungal infection of barley in the field which may result in elevated antimicrobial activity in the barley grain. Also, two more malts that passed the normal quality control tests were also observed to have high antiyeast activity and such malts must be considered as suspect. Based on our results, this assay is a useful measure of malt quality as it quantifies the antiyeast activity in malt which may adversely impact on brewery fermentation. PMID:18721679

    Fusarium infections in grains can have severe effects on malt and beer. While some degree of Fusarium mycotoxins, such as deoxynivalenol, present in infected barley may be lost during steeping, the Fusarium mold is still capable of growth and mycotoxin production during steeping, germination and kilning. Therefore, detoxification of grain before malting may not be practical unless further growth of the mold is also prevented. Methods to reduce the amount of mold growth during malting are needed. Physical, chemical and biological methods are reviewed. Irradiation looks very promising as a means to prevent Fusarium growth during malting, but the effect on the surviving mold to produce mycotoxins and the effect on malt quality needs further study. Chemical treatments such as ozonation, which would not leave residual chemical in the beer also appear to be promising. Although biological control methods may be desirable, due to the use of "natural" inhibition, the effects of these inhibitors on malt and beer quality requires further investigation. It may also be possible to incorporate detoxifying genes into fermentation yeasts, which would result in detoxification of the wort when mold growth is no longer a problem. Development of these types of technological interventions should help improve the safety of products, such as beer, made from Fusarium infected grain. PMID:17727998

    The Great Western Malting Company recently constructed a barley malting facility in Pocatello, Idaho, designed to produce 6.0 million bushels per year of brewing malt. This facility uses natural gas to supply the energy for germination and kilning processes. The escalating cost of natural gas has prompted the company to look at alternate and more economical sources of energy. Trans Energy Systems has investigated the viabiity of using geothermal energy at the new barley processing plant. Preliminary investigations show that a geothermal resource probably exists, and payback on the installation of a system to utilize the resource will occur in under 2 years. The Great Western Malting plant site has geological characteristics which are similar to areas where productive geothermal wells have been established. Geological investigations indicate that resource water temperatures will be in the 150 to 200/sup 0/F range. Geothermal energy of this quality will supply 30 to 98% of the heating requirements currently supplied by natural gas for this malting plant. Trans Energy Systems has analyzed several systems of utilizing the geothermal resource at the Great Western barley malting facility. These systems included: direct use of geothermal water; geothermal energy heating process water through an intermediary heat exchanger; coal or gas boosted geothermal systems; and heat pump boosted geothermal system. The analysis examined the steps that are required to process the grain.

    Full Text Available Since there is evidence that malting quality is related to the storage protein (hordein fraction, in the present work the hordein polypeptide patterns from 13 barley (Hordeum vulgare L. varieties of different malting quality were analysed in order to explore the feasibility of using hordein electrophoresis to assist in the selection of malting barleys. The formation of clusters separating the varieties with higher malting quality from the others with lower quality suggests that there is a relationship between the general hordein polypeptide pattern and malting quality in the varieties analysed. By the Sperman's correlation test three hordein bands correlated negatively with malting quality in the germplasm studied.

    2013-12-01

    Full Text Available Hydrolysis of barley proteins into peptides and amino acids is one of the most important processes during barley germination.The degradation of the endosperm stored proteins facilitates water and enzyme movements, enhances modification, liberates starch granules and increases soluble amino nitrogen. Protease activity is the result of the activities of a mixture of exo- and endo-proteases. The barley proteins are initially solubilized by endo-proteases and the further by exo-proteases. Four classes of endo-proteases have been described: serine-proteases, cysteine-proteases, aspartic-proteases and metallo-proteases. The objective of this work was to develop a rapid and colorimetric enzymatic assay to determine the endo-proteolytic activity of the four endo-protease classes using two different substrates: azo-gelatin and azo-casein. Optimum conditions for the assays such as: pH,reaction time and temperature and absorbance scale were determined. Azo-gelatin presented several difficulties in standardizing an “in solution” assay. On the other hand, azo-casein allowed standardization of the assay for the four enzyme classes to produce consistent results. The endo-proteoteolytic method developed was applied to determine the endo-protease activity in barley, malt and wort.

    2010-01-01

    Sorghum malt and dolo quality evaluation criteria and parameters affecting quality were surveyed in six cities in Burkina Faso through questionnaires addressed to malt processors, dolo processors, retailers, and consumers. The major quality criteria for malt quality assessment were perceived to be taste and presence/absence of roots in the malt. Taste, alcohol content, and wort sufficiently cooked were perceived as major criteria for the dolo quality assessment. The major parameters affecting malt quality were perceived to be malt production period, proportions of grain and the amount of water entering malting, presence of pesticide residues in the malting grains, and age of grain. Processing method, yeast source, proportions of the components (crushed grain, water, mucilage, yeast) entering dolo production, malt quality, wort temperature at time of inoculation, amount of energy available for cooking, wort and sediment boiling time, quality of mucilage, malt with non-sweet taste, presence/absence of roots in the malt, and ease of filtering crushed malt were perceived as major parameters affecting the dolo quality. These results will be used in the improvement of the dolo supply chain in Burkina Faso by providing more reliable information for training programs for efficient dolo brewing processes, development of best cropping practices to improve grain quality, and providing better selection criteria for sorghum breeding programs.

    The scientific STAFF and MALT meetings were created around the turn of the century for scientists engaged in enhancing the role of the 12-lead ECG for detection and quantification of involved myocardium in patients with acute coronary syndrome. These meetings were initially focused on computer processing of data from two single-center databases. The STAFF database was collected in the mid-nineties on patients with prolonged total coronary occlusion; high-resolution 12-lead ECGs were collected before, during, and after 5 minutes of occlusion. The MALT database was created in the early years of this century on consecutive patients with chest pain admitted to a large teaching hospital. Delayed enhancement magnetic resonance imaging and electrocardiograms were recorded in these acutely ill patients. The paper highlights the first 2 decades of the STAFF and MALT meetings and details the meeting format. PMID:26987617

    Gibson, Nigel B.; Costigan, Gavin T.; Swannell, Richard P. J.; Woodfield, Michael J.

    Estimates have been made of the amounts of volatile organic compounds (VOCs) released during different stages of beer manufacture. The estimates are based on recent measurements and plant specification data supplied by manufacturers. Data were obtained for three main manufacturing processes (malting, wort processing and fermentation) for three commercial beer types. Some data on the speciation of emitted compounds have been obtained. Based on these measurements, an estimate of the total unabated VOC emission. from the U.K. brewing industry was calculated as 3.5 kta -1, over 95% of which was generated during barley malting. This value does not include any correction for air pollution control.

    Malted barley is a major raw material of beer, as well as distilled spirits and several food products. The production of malt (malting) exploits the biochemical reactions of a natural process, grain germination. In addition to germinating grain, the malting process includes another metabolically active component: a diverse microbial community that includes various types of bacteria and fungi. Therefore, malting can be considered as a complex ecosystem involving two metabolically active groups. Yeasts and yeast-like fungi are an important part of this ecosystem, but previously the significance of yeasts in malting has been largely underestimated. Characterization and identification of yeasts in industrial processes revealed 25 ascomycetous yeasts belonging to 10 genera, and 18 basidiomycetous yeasts belonging to 7 genera. In addition, two ascomycetous yeast-like fungi belonging to the genera Aureobasidium and Exophiala were commonly detected. Yeasts and yeast-like fungi produced extracellular hydrolytic enzymes with a potentially positive contribution to the malt enzyme spectrum. Several ascomycetous yeast strains showed strong antagonistic activity against field and storage moulds, Wickerhamomyces anomalus (synonym Pichia anomala) being the most effective species. Malting studies revealed that W. anomalus VTT C-04565 effectively restricted Fusarium growth and hydrophobin production during malting and prevented beer gushing. In order to broaden the antimicrobial spectrum and to improve malt brewhouse performance, W. anomalus could be combined with other starter cultures such as Lactobacillus plantarum. Well-characterized microbial mixtures consisting of barley and malt-derived microbes open up several possibilities to improve malt properties and to ensure the safety of the malting process.

    Mercury (Hg) concentrations were measured in 26 Scottish single malt whiskies, and all found to be very low (atmospheric deposition. We speculate that this gradient could be due to a combination of contemporary deposition and the legacy of industrial mercury emissions and deposition over the last 200 years affecting concentrations in local waters used in whisky production. As UK atmospheric emissions of mercury have declined by 90 % since the 1970s, we suggest that whisky being produced today should have even lower Hg concentrations when consumed in 10- to 15-years time. This reduction may be compromised by the remobilisation of contaminants stored in catchment soils being transferred to source waters, but is very unlikely to raise the negligible health risk due to Hg from Scottish single malt whisky consumption.

    Inferior and unstable quality of malt barley in China has limited its wide use in malting and brewing industries. In this research, eight two-rowed barley cultivars were planted at 7 locations with different ecological conditions in southern China, to investigate the cultivar and environmental effect on grain and malt qualities. The results showed that grain protein content differed dramatically among locations, but there were no significant differences among cultivars. For four malt qualities including diastatic power, wort viscosity,Kolbach index and malt extract, significant differences were found among cultivars and locations, except for diastatic power among cultivars. Coefficients of variance (CV) caused by location were greater than those caused by cuitivar for each quality parameter, especially for diastatic power and Kolbach index, indicating the predominant influence of environment on malt quality. The analysis showed that grain protein content was positively related to diastatic power and wort viscosity, and negatively to malt extract. Kolbach index was positively related to malt extract, and negatively to diastatic power and wort viscosity. Diastatic power showed positive and negative correlation with wort viscosity and malt extract, respectively.

  19. Primary radiotherapy is curative for CS IE orbital malt lymphoma

    International Nuclear Information System (INIS)

    PURPOSE: With the adoption of the International Lymphoma Study Group (ILSG) recommendations for classification of the non-Hodgkin's lymphomas, low grade extranodal lymphoma of mucosa associated lymphoid tissue (MALT) has become an increasingly more common pathologic diagnosis. Due to its relatively recent description, natural history and optimal management of MALT lymphomas remains unsettled. We have identified 22 cases of orbital MALT lymphoma and report on their outcome. MATERIALS and METHODS: Pathologic biopsies of 92 patients with CS I extranodal lymphoma were reviewed and reclassified using the ILSG recommendations. Twenty-two cases of low grade orbital MALT lymphoma were identified. Fifteen cases were conjunctival and 7 were retrobulbar. Staging workup included chest radiograph in 100%, Head/Orbital CT scan in 95%, Abdominopelvic CT scan in 79%, lymphangiogram in 32%, and bone marrow biopsy in 50%. Conjunctival lymphomas were treated with anterior superficial x-rays or 9-12 MeV electrons utilizing a central eye bar. Retrobulbar lymphomas were treated with 4-6 MV photons utilizing wedged pairs, arcs or single anterior photon fields (with eye bar). Mean dose was 34 Gy (range 30-40 Gy). No patient received chemotherapy or curative intent surgery. RESULTS: With mean follow-up of 7.7 years (range 2 mo - 19 yr), the 10 year actuarial overall and disease specific survival was 90%. At 10 years, actuarial freedom from local recurrence was 100% while freedom from any relapse was 71%. Among 9 patients followed for longer than 10 years none have experienced a relapse. Among patients (pts) who relapsed, all failed in extranodal sites where MALT lymphomas have been described (larynx - 1 pt, abdomen - 1 pt, lung - 1 pt, and contralateral conjunctiva - 1 pt) and none failed in a nodal site. Acute toxicity included excessive tearing (3 pts), mild diplopia (1 pt), periorbital edema (3 pts), and marked erythema (1 pt). Two patients required a one week treatment break and no

    Full Text Available CARMA-BCL10-MALT1 signalosomes play important roles in antigen receptor signaling and other pathways. Previous studies have suggested that as part of this complex, MALT1 functions as both a scaffolding protein to activate NF-κB through recruitment of ubiquitin ligases, and as a protease to cleave and inactivate downstream inhibitory signaling proteins. However, our understanding of the relative importance of these two distinct MALT1 activities has been hampered by a lack of selective MALT1 protease inhibitors with suitable pharmacologic properties. To fully investigate the role of MALT1 protease activity, we generated mice homozygous for a protease-dead mutation in MALT1. We found that some, but not all, MALT1 functions in immune cells were dependent upon its protease activity. Protease-dead mice had defects in the generation of splenic marginal zone and peritoneal B1 B cells. CD4+ and CD8+ T cells displayed decreased T cell receptor-stimulated proliferation and IL-2 production while B cell receptor-stimulated proliferation was partially dependent on protease activity. In dendritic cells, stimulation of cytokine production through the Dectin-1, Dectin-2, and Mincle C-type lectin receptors was also found to be partially dependent upon protease activity. In vivo, protease-dead mice had reduced basal immunoglobulin levels, and showed defective responses to immunization with T-dependent and T-independent antigens. Surprisingly, despite these decreased responses, MALT1 protease-dead mice, but not MALT1 null mice, developed mixed inflammatory cell infiltrates in multiple organs, suggesting MALT1 protease activity plays a role in immune homeostasis. These findings highlight the importance of MALT1 protease activity in multiple immune cell types, and in integrating immune responses in vivo.

    The protease activity of the paracaspase mucosa-associated lymphoid tissue lymphoma translocation gene 1 (MALT1) plays an important role in antigen receptor-mediated lymphocyte activation by controlling the activity of the transcription factor nuclear factor-κB and is thus essential for the expression of inflammatory target genes. MALT1 is not only present in cells of the hematopoietic lineage, but is ubiquitously expressed. Here we report that stimulation with zymosan or Staphylococcus aureus induced MALT1 protease activity in human primary keratinocytes. Inhibition of the Src family of kinases or novel protein kinase C isoforms as well as silencing of CARMA2 or BCL10 interfered with activation of MALT1 protease. Silencing or inhibition of MALT1 protease strongly decreased the expression of important inflammatory genes such as TNFα, IL-17C, CXCL8 and HBD-2. MALT1-inhibited cells were unable to mount an antimicrobial response upon zymosan stimulation or phorbolester/ionomycin treatment, demonstrating a central role of MALT1 protease activity in keratinocyte immunity and suggesting MALT1 as a potential target in inflammatory skin diseases.

    Jaworski, Maike; Thome, Margot

    2016-02-01

    The paracaspase MALT1 has a central role in the activation of lymphocytes and other immune cells including myeloid cells, mast cells and NK cells. MALT1 activity is required not only for the immune response, but also for the development of natural Treg cells that keep the immune response in check. Exaggerated MALT1 activity has been associated with the development of lymphoid malignancies, and recently developed MALT1 inhibitors show promising anti-tumor effects in xenograft models of diffuse large B cell lymphoma. In this review, we provide an overview of the present understanding of MALT1's function, and discuss possibilities for its therapeutic targeting based on recently developed inhibitors and animal models.

  7. Malting Characteristics of Some Sorghum and Millet Grain Varieties Grown in Kenya

    International Nuclear Information System (INIS)

    Industrial malt in Kenya for commercial beer production is made exclusively from barley. This study explored the potential of producing suitable malt from some sorghum and finger millet grain varieties grown in Kenya. Malting characteristics of two sorghum grain varieties, KARI Mtama-1 and local Red variety, and that of finger millet was done and compared to that of barley. Among the grain characteristics determined before malting were water sensitivity, polyphenol (tannin) content and total protein. The grain was malted by striping in water for 48 h, followed by germination for four days at 25 degrees celcious, then kilned at 50 degrees celcious for 24 h. The malting characteristics determined included total soluble N, free amino N, wort pH and fermentable sugars. The local red sorghum and millet had high polyphenol content while KARI Mtama-1 and barley had low levels. KARI Mtama-1 had positive water sensitivity while barley had negative sensitivity. Finger millet and local red sorghum were water insensitive. Free amino N was 113, 125, 144, and 154mg 100g-1 malt for millet, barley, local Red and KARI Mtama-1, respectively. Total fermentation sugars were 307, 477, 610 and 178 mg 1-1 for finger millet, local red, barley and KARI Mtama1, respectively. The results showed that that the proteolytic and amyloytic characteristics of the KARI Mtama-1 malt are largely similar to those of barley. Hence the KARI Mtama-1 malt are largely similar to those of barley. Hence the KARI Mtama-1 has good potential fro conventional lager beer production. Malts of local Red sorghum grain and millet may be more suitable for industrial production of opaque/cloudy beer

  8. Energy and exergy analyses of malt drink production in Nigeria

    International Nuclear Information System (INIS)

    Energy requirements and exergy inefficiencies for processing of malt drink were estimated for a Nigerian brewery. The process was divided into twenty-one basic unit operations and grouped into four main group operations: silo house, brew house, filter room and packaging house. The energy intensity for processing a batch of 9.8 tonnes brew grains to 562 hl of malt drink was estimated as 261.63 MJ/hl consisting of electrical (41.01%), thermal (58.81%) and manual (0.19%) of the total energy. The most energy intensive group operation was the Packaging House operation, followed by the Brew House operation with energy intensities of 223.19 and 35.94 MJ/hl, respectively. The exergy analysis revealed that the packaging house operation was responsible for most of the inefficiency (92.16%) followed by brew house operation (7.17%) and the silo house and filter room operations with less than 1% of the total exergy lost. The most exergy loss took place in the pasteurizer, which accounted for 59.75% of the overall system inefficiency. Modification in the pasteurizer and use of spent grains as alternate source of energy in the steam boiler were recommended to improve the energy efficiency of the system.

    Full Text Available A água de umidificação de malte, resultante da moagem úmida, pode ser usada como matéria prima na fabricação de cerveja. Há, entretanto, cervejarias que descartam esse subproduto, e conseqüentemente, o extrato nele contido. Em função disso, o presente trabalho teve por objetivo avaliar a possibilidade de ganho de rendimento na mosturação e alterações nas características químicas e sensoriais da bebida, em virtude do uso dessa água. Cervejas do tipo Pilsen foram produzidas de duas formas: com e sem água de umidificação de malte. Utilizou-se como matéria prima malte, lúpulo, xarope de maltose, água destilada e água de umidificação de malte. O mosto foi produzido pelo processo de infusão, separado do bagaço de malte por filtração convencional e fervido durante 60 minutos. Após seu resfriamento e clarificação o mosto foi inoculado com levedura de baixa fermentação (1,3g/l, ps e colocado para fermentar a 10°C. A fermentação foi encerrada com 90% da atenuação limite. Em seguida, a cerveja foi engarrafada e maturada a 0°C por 14 dias. Os resultados mostraram que o aumento do rendimento de mosturação, em função do uso da água de umidificação de malte, foi estatisticamente não significativo. A utilização dessa água praticamente não alterou as características químicas e sensoriais da cerveja, havendo apenas um leve aumento na intensidade de cor da bebida (7,1 x 8,0 EBC. Considerando, no entanto, que a água de umidificação de malte obtida em nível industrial apresenta maior concentração de extrato em relação àquela produzida em laboratório, espera-se que o uso da primeira traga ganho de rendimento industrial sem alterações significativas nas características da cerveja.The wet milling malt steep water can be used as raw material on brewing. However, some breweries discard this water containing a certain amount of extract. Based on this fact, the aim of this work was to evaluate possible

    Reportedly, thyroid mucosa-associated lymphoid tissue (MALT lymphoma is closely associated with Hashimoto's thyroiditis. However, it remains unknown which antigen is closely associated with thyroid MALT lymphoma. We examined whether B cell response to thyroglobulin (Tg, which is a common thyroid-specific autoantigen, is related etiologically to the pathogenesis of thyroid MALT lymphoma. Expression of human Tg antigens and Cluster of differentiation (CD 35 was examined immunohistochemically in 15 cases of thyroid MALT lymphoma using paraffin-embedded, formalin-fixed tissue specimens. In all cases of thyroid MALT lymphoma, human Tg was detected immunohistochemically in the follicular epithelial cells and follicular dendritic cells (FDCs. These FDCs were positive by double immunostaining for anti-human Tg rabbit polyclonal antibody (Ab and for CD35. Results showed that the Tg, a thyroid autoantigen, had immunostained the germinal center of the thyroid MALT lymphoma. The Tg was present in the FDCs, as revealed by the staining pattern of the germinal center;this fact was confirmed by double immunostaining of anti-human Tg mouse monoclonal Ab and anti-CD35 mouse monoclonal Ab. The results of our study suggest that Tg is an autoantigen that is recognized by thyroid MALT lymphoma cells.

    2008-10-01

    Low-malt beers, in which the amount of wort is adjusted to less than two-thirds of that in regular beer, are popular in the Japanese market because the flavor of low-malt beer is similar to that of regular beer but the price lesser than that of regular beer. There are few published articles about low-malt beer. However, in the production process, there are many similarities between low-malt and regular beer, e.g., the yeast used in low-malt beer fermentation is the same as that used for regular beer. Furthermore, many investigations into regular beer are applicable to low-malt beer production. In this review, we focus on production of volatile compounds, and various studies that are applicable to regular and low-malt beer. In particular, information about metabolism of volatile compounds in yeast cells during fermentation, volatile compound measurement and estimation methods, and control of volatile compound production are discussed in this review, which concentrates on studies published in the last 5-6 years.

    1999-01-01

    Barley grain carries a numerous, variable, and complex microbial population that mainly consists of bacteria, yeasts, and filamentous fungi and that can partly be detected and quantified using plating methods and microscopic and molecular techniques. The extent and the activity of this microflora are determined by the altering state of the grain and the environmental conditions in the malt production chain. Three ecological systems can be distinguished: the growing cereal in the field, the dry barley grain under storage, and the germinating barley kernel during actual malting. Microorganisms interact with the malting process both by their presence and by their metabolic activity. In this respect, interference with the oxygen uptake by the barley grain and secretion of enzymes, hormones, toxins, and acids that may affect the plant physiological processes have been studied. As a result of the interaction, microorganisms can cause important losses and influence malt quality as measured by brewhouse performance and beer quality. Of particular concern is the occurrence of mycotoxins that may affect the safety of malt. The development of the microflora during malt production can to a certain extent be controlled by the selection of appropriate process conditions. Physical and chemical treatments to inactivate the microbial population on the barley grain are suggested. Recent developments, however, aim to control the microbial activity during malt production by promoting the growth of desirable microbial cultures, selected either as biocontrol agents inhibiting mycotoxin-producing molds or as starter cultures actively contributing to malt modification. Such techniques may offer natural opportunities to improve the quality and safety of malt. PMID:10405796

    Full Text Available Maltodextrin is a mixture of saccharides with a molecular weight between polysaccharides and oligosaccharides with DE lower than 20. Maltodextrin is more soluble in water than native starches, also is cheaper in comparison with other major edible hydrocolloids. Maltodextrin is obtained by moderate enzymatic or acidic hydrolysis of starch. The hydrolysis of starch, catalyzed by amylases, is the most important commercial enzyme process. The hydrolyzed products are widely applied in food, paper and textile industries. Because of the increasing demand for these enzymes in various industries, there is enormous interest in developing enzymes with better properties, such as raw starch-degrading amylases suitable for industrial applications and their cost-effective production techniques. Sorghum (Sorghum bicolor is a widely grown crop in Africa. Obtaining enzymes from sorghum requires a transformation. The objective of this study was application of sorghum amylase for maltodextrin. Sorghum seeds were supplied by the ISRA (Bambey, Senegal. Seeds were germinated in the laboratory at 30°C for 72 h and the sorghum malt was dried at 40°C for 48 h. Corn starch (from Roquette, France hydrolysis was assayed in a bioreactor of 2 l at a temperature of 65°C gently stirred. Raw starch was slurried in water (30% w/v and sorghum malt was introduced, chloride calcium was added, pH was adjusted to 6. Maltodextrin was characterized in term of the dextrose equivalent (DE during the hydrolysis. The yield of hydrolysis was evaluated by soluble solids (° BRIX at different hydrolysis time.

    Fusarium infection of barley and malt can cause severe problems in the malting and brewing industry. In addition to being potential mycotoxin producers, Fusarium fungi are known to cause beer gushing (spontaneous overfoaming of beer). Cereal-derived bacteria and yeasts are potential biocontrol agents. In this study, the antifungal potential of selected yeasts (12 strains) derived from the industrial malting ecosystem was studied in vitro with a plate-screening assay. Several ascomycetous yeast strains showed antagonistic activity against field and storage moulds, Pichia anomala being the most effective strain. The effects of P. anomala VTT C-04565 (C565) were examined in laboratory scale malting with naturally contaminated barley exhibiting gushing potential. P. anomala C565 restricted Fusarium growth and hydrophobin production during malting and prevented beer gushing. Grain germination was not disturbed by the presence of yeast. Addition of P. anomala C565 into the steeping seemed to retard wort filtration, but the filtration performance was recovered when yeast culture was combined with Lactobacillus plantarum VTT E-78076. Well-characterized microbial cultures could be used as food-grade biocontrol agents and they offer a natural tool for tailoring of malt properties. PMID:17680285

  2. Effect of radiotherapy on MALT lymphomas not responding to H. pylori eradication

    International Nuclear Information System (INIS)

    Gastric and duodenal mucosa-associated lymphoid tissue (MALT) lymphomas were classified into 4 groups (Group A, B, C, and D) by the existence of API2-MALT1 chimeric transcript, H. pylori infection and its response to H. pylori eradication. Cases in group A were API2-MALT1 negative, H. pylori positive which responded to H. pylori eradication. Non responders were classified into group B. Cases in group C were API2-MALT1 negative and H. pylori negative. Group D was API2-MALT1 positive. Twenty two cases of clinical stage I in group B, C and D which did not respond to eradication (2 cases also had chemotherapy) received radiotherapy and all of them achieved complete response. Acute toxicities were only grade 1 digestive symptoms and grade 1-2 hematologic toxicities and late toxicity was seen in only one case as grade 2 nephropathy. Nephropathy was avoided by the multi-field technique instead of the 2-field technique. Radiotherapy can be an effective and safe treatment for gastric and duodenal MALT lymphomas in clinical stage I.

    2016-04-28

    Extranodal marginal zone (MZ) B-cell lymphomas of the mucosa-associated lymphoid tissue (MALT) arise from lymphoid populations that are induced by chronic inflammation in extranodal sites. The best evidence of an etiopathogenetic link is provided by the association between Helicobacter pylori-positive gastritis and gastric MALT lymphoma. Indeed, successful eradication of this microorganism with antibiotics can be followed by gastric MALT lymphoma regression in most cases. Other microbial agents have been implicated in the pathogenesis of MZ lymphoma arising at different sites. Apart from gastric MALT lymphoma, antibiotic therapies have been adequately tested only in ocular adnexal MALT lymphomas where upfront doxycycline may be a reasonable and effective initial treatment of patients with Chlamydophila psittaci-positive lymphoma before considering more aggressive strategies. In all other instances, antibiotic treatment of nongastric lymphomas remains investigational. Indeed, there is no clear consensus for the treatment of patients with gastric MALT lymphoma requiring further treatment beyond H pylori eradication or with extensive disease. Both radiotherapy and systemic treatments with chemotherapy and anti-CD20 antibodies are efficacious and thus the experience of individual centers and each patient's preferences in terms of adverse effects are important parameters in the decision process.

  4. Uncoupling Malt1 Threshold Function from Paracaspase Activity Results in Destructive Autoimmune Inflammation

    Directory of Open Access Journals (Sweden)

    Andreas Gewies

    2014-11-01

    Full Text Available The paracaspase Malt1 is a central regulator of antigen receptor signaling that is frequently mutated in human lymphoma. As a scaffold, it assembles protein complexes for NF-κB activation, and its proteolytic domain cleaves negative NF-κB regulators for signal enforcement. Still, the physiological functions of Malt1-protease are unknown. We demonstrate that targeted Malt1-paracaspase inactivation induces a lethal inflammatory syndrome with lymphocyte-dependent neurodegeneration in vivo. Paracaspase activity is essential for regulatory T cell (Treg and innate-like B cell development, but it is largely dispensable for overcoming Malt1-dependent thresholds for lymphocyte activation. In addition to NF-κB inhibitors, Malt1 cleaves an entire set of mRNA stability regulators, including Roquin-1, Roquin-2, and Regnase-1, and paracaspase inactivation results in excessive interferon gamma (IFNγ production by effector lymphocytes that drive pathology. Together, our results reveal distinct threshold and modulatory functions of Malt1 that differentially control lymphocyte differentiation and activation pathways and demonstrate that selective paracaspase blockage skews systemic immunity toward destructive autoinflammation.

    Germination can be used to improve the sensory and nutritional properties of cereal and pseudocereal grains. Oat and quinoa are rich in minerals, vitamins and fibre while quinoa also contains high amounts of protein of a high nutritional value. In this study, oat and quinoa malts were produced and incorporated in a rice and potato based gluten free formulation. Germination of oat led to a drastic increase of α-amylase activity from 0.3 to 48 U/g, and minor increases in proteolytic and lipolytic activities. Little change was observed in quinoa except a decrease in proteolytic activity from 9.6 to 6.9 U/g. Oat malt addition decreased batter viscosities at both proofing temperature and during heating. These changes led to a decrease in bread density from 0.59 to 0.5 g/ml and the formation of a more open crumb, but overdosing of oat malt deteriorated the product as a result of excessive amylolysis during baking. Quinoa malt had no significant effect on the baking properties due to low α-amylase activity. Despite showing a very different impact on the bread quality, both malts influenced the electrophoretic patterns of rice flour protein similarly. This suggests that malt induced proteolysis does not influence the technological properties of a complex gluten free formulation. PMID:23386201

    Full Text Available Abstract Ocular adnexa MALT-lymphomas represent approximatively 5-15% of all extranodal lymphomas. Almost 75% of OAMLs are localized in orbital fat, while 25% of cases involves conjunctive. MALT-lymphomas often recognize specific environmental factors responsible of lymphoma development and progression. In particular as Helicobacter pylori in gastric MALT lymphomas, other bacterial infections have been recognized related to MALT lymphomas in specific site. Recently Chlamydia psittaci has been identified in Ocular Adnexa MALT lymphomas, with variable frequence dependently from geographic areas. Thus bacterial infection is responsible of clonal selection on induced MALT with subsequent lymphoma development. Moreover Chlamydia psittaci could promote chromosomal aberration either through genetic instability as a consequence of induced proliferation and probably through DNA oxidative damage. The most common translocation described in MALT lymphomas affects NF-kB pathway with a substantial antiapoptotic effect. Several therapeutic approaches are now available, but the use of antibiotic-therapy in specific cases, although with conflicting results, could improve the treatment of ocular adnexa MALT lymphomas. In this review we analyse the most relevant features of Ocular adnexa MALT lymphomas, underlining specific biological characteristics mainly related to the potential role of Chlamydia psittaci in lymphomagenesis.

    Full Text Available Background/Aim. Lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma of the stomach usually occurs as a consequence of Helicobacter pylori (H. pylori infection. The aim of this study was to investigate the long-term effect of treatment of low-grade gastric MALT lymphoma with the H. pylori eradication method. Methods. In the period 2002-2012 in 20 patients with dyspepsia, mean age 55.1 years, the endoscopic and histologic diagnosis of gastric MALT lymphoma in the early stages were made. Histological preparations of endoscopic biopsy specimens were stained with hematoxyllineosin (HE, histochemical and immunohistochemical methods. Results. Endoscopic findings of gastritis were documented in 25% of the patients, and 75% of the patients had hypertrophic folds, severe mucosal hyperemia, fragility, nodularity, exulcerations and rigidity. Histopathologically, pathognomonic diagnostic criterion were infiltration and destruction of glandular epithelium with neoplastic lymphoid cells, the so-called lymphoepithelial lesions. In all 20 patients H. pylori was verified by rapid urease test and Giemsa stain. After the triple eradication therapy complete remission of MALT lymphoma was achieved in 85% of the patients, with no recurrence of lymphoma and H. pylori infection in the average follow-up period of 48 months. In 3 (15% of the patients, there was no remission of MALT lymphoma 12 months after the eradication therapy. Of these 3 patients 2 had progression of MALT lymphoma to diffuse large-cell lymphoma. Conclusion. Durable complete re-mission of low-grade gastric MALT lymphoma is achieved in a high percentage after eradication of H. pylori infection, thus preventing the formation of diffuse large-cell lymphoma and gastric adenocarcinoma.

    Full Text Available Beer manufacturing is one of the most ancient procedures of food manufacturing. The four (in many cases much more ingredients, the great numbers of technological steps and variations of technological parameters (temperature, time, pressure etc. have a major influence on both type and quality of the final product. As a result of this, studying beer brewing may offer a great deal of possibilities for numerous researches, scientific examinations, and can provide useful informations for the manufacturing companies as well. At the „Slovak University of Agriculture in Nitra" we examined an entire beer brewing process in October 2013, utilising the Ahlborn sensors, which were integrated in the instruments. Simultaneously, in Gödöllő at the Szent István University, we analysed the effect of malt milling on extract yield and the filterability of wort. We used the brewing parameters (temperature, time, volume ratios, which were experienced in the microbrewery and published in professional literature. Our results verify the conclusions drawn in the professional literature, however they point out the importance of grinding. Results performed on the yields with different grain-constitution might directly be utilised for the specialists of recently in Slovakia and Hungary spreading small-scale, handicraft, and homemade beer brewing.

  10. Mucosa associated lymphoid tissue (MALT lymphoma) of the urinary bladder: a case report

    International Nuclear Information System (INIS)

    Full text: Mucosa associated lymphoid tissue (MALT lymphoma) of the urinary bladder is a rare condition. The best treatment approach for this disease is controversial. A case report on a patient with MALT lymphoma of the urinary bladder. The relevant current literature was reviewed. A 79 year old lady presented with haematuria in 2002. Ultrasound of the pelvis showed a large tumour in the bladder. Cystoscopy revealed a mass arising from the bladder. Transurethral resection of the tumour was performed. Histology showed Non Hodgkin's lymphoma of MALT type. CT showed a 8.9 X 7.6 cm solid tumour involving almost whole of the bladder. The patient could not tolerate anti helicobacter treatment and was then treated with radiotherapy. The pelvis was treated with 18 MV photons with a 3 field technique in 2 phases, with CT planning. In phase 1, the pelvis was treated to 24 Gy in 12 fractions, over 2.5 weeks. Phase 2 was treated to a reduced pelvic field, to a dose of 16 Gy in 8 fractions over 1.5 weeks. Five months after radiotherapy, repeat cystoscopy and biopsy of bladder base showed no evidence of malignancy. MALT lymphoma of the urinary bladder responds well to radiotherapy and permits bladder preservation. The current literature in management of MALT lymphoma of urinary bladder is reviewed

    Full Text Available The stomach is one of the most common organs in which mucosa-associated lymphoid tissue (MALT lymphoma develops. It is well established that Helicobacter pylori (Hp infection plays a major role in the development of gastric MALT lymphoma and that the presence of Hp in the gastric mucosa is connected with mucosa-associated lymphatic tissue (MALT.The same tissue is located in the oral cavity and pharynx in Waldayer’s circuit. Recently, the oral cavity was proposed as an extragastric reservoir of Hp infection. We report the case of a 79-year-old female patient with concomitant pharyngeal (MALT lymphoma and Hp-related gastric MALT lymphoma. Gastric MALT lymphoma was detected both through endoscopic examination as well as in biopsies. Pharyngeal MALT lymphoma was also detected in biopsies. Hp has been recognized in the gastric mucosa by positive serum H. pylori antibody and urease tests. Treatment of the Hp infection in our patient using antibiotics led to the regression of both lesions. This is the first case report on the regression of a pharyngeal MALT lymphoma after Hp eradication.

    ALMA will revolutionize our understanding of star formation within our galaxy, but before we can use ALMA we need to know where to look. The Millimeter Astronomy Legacy Team 90 GHz (MALT90) Survey is a large international project to map the molecular line emission of over 2,000 dense clumps in the Galactic plane. MALT90 serves as a pathfinder for ALMA, providing a large public database of dense molecular clumps associated with high-mass star formation. In this proceedings, we describe the survey parameters and share early science highlights from the survey, including (1) a comparison between galactic and extragalactic star formation relations, (2) chemical trends in MALT90 clumps, (3) the distribution of high-mass star formation in the Milky Way, and (4) a discussion of the Brick, the target of successful ALMA Cycle 0 and Cycle 1 proposals.

  14. Radiological features in paediatric primary gastric MALT lymphoma and association with Helicobacter pylori

    International Nuclear Information System (INIS)

    Primary malignant tumours of the stomach are very rare in children, most being lymphomas and sarcomas. The majority of primary gastric lymphomas are high-grade non-Hodgkin's lymphomas and are of B-cell origin. However, a significant number are low-grade B-cell lymphomas that are derived from mucosa-associated lymphoid tissue (MALT) that is not found in the normal stomach. Helicobacter pylori infection predisposes to the development of MALT in the stomach and provides the pathogenic background for MALT-type lymphomagenesis. To our knowledge, only eight paediatric cases of primary gastric lymphoma have been described. The diagnosis and follow-up of gastric lymphoma are mainly made by endoscopy. Nevertheless, radiologists must be aware of this disease because it may be observed on radiological examinations that are performed for non-specific upper digestive symptoms in children. (orig.)

    2010-07-01

    Full Text Available Primary MALT lymphoma of the prostate is a rare disease which characteristically follows an indolent course. It is believed that infection or chronic inflammation may be triggers for malignant transformation in the prostate, but it is of unknown etiology. Reports of MALT lymphomas of the prostate with other concurrent primary prostate cancers are even more limited. We present the unique case of a 67 year old male with concurrent adenocarcinoma of the prostate and primary MALT lymphoma of the prostate. The patient was treated with standard therapy for prostate adenocarcinoma, which also sufficiently would treat a primary MALT lymphoma. He has been disease-free for over one year for both his primary malignancies. This case confirms that MALT lymphoma can arise concurrently with adenocarcinoma of the prostate.

  17. Investigating the Gao & Solomon Relationship with MALT90

    2016-01-01

    In an survey of 53 galaxies, Gao & Solomon (2004) found a tight linear relationship between the infrared luminosity (a proxy for the star formation rate) and the HCN(1-0) luminosity, which is known as the Gao & Solomon relationship. Wu et al. (2005, 2010) found that this relationship extends from these extragalactic sources to the much less luminous Galactic clumps (~1 pc scales), and posited that there exists a fundamental unit for the ratio between infrared luminosity and dense gas mass for high-mass star-forming clumps. The luminosities of the Gao & Solomon (2004) galaxies could then be explained as a summation of this fundamental unit in the form of high-mass star-forming clumps. We test this explanation and other possible origins of the Gao-Solomon relationship using high-density tracers (including HCN(1-0), N2H+(1-0), HCO+(1-0), HNC(1-0), HC3N(10-9), and C2H(1-0)) for ~400 Galactic clumps from the Millimetre Astronomy Legacy Team 90 GHz (MALT90) survey. Along with ancillary data, we find that this fundamental unit is not likely to exist at the clump-scale. Specifically, there are not enough high-mass clumps in the Milky Way to achieve the total expected luminosity of the Galaxy. Extended infrared emission, which often lacks high-mass clumps, adds significant (and probably dominant) emission to the total infrared luminosity of a galaxy. Low-mass clumps appear to add a significant, if not dominant, component to a galaxy's total HCN(1-0) luminosity. We suggest that Gao & Solomon relationship could be a result of a universal large-scale star formation efficiency, initial mass function, clump mass function, and core mass function. The power-law slope of the Gao & Solomon relationship probably depends on the critical density of the tracer and the median density of the galaxy, as suggested in theoretical simulations.

    Directory of Open Access Journals (Sweden)

    Karine Sampaio LIMA

    2014-04-01

    Full Text Available Context Gastric mucosa-associated lymphoid tissue (MALT lymphoma is clearly associated with Helicobacter pylori gastritis and can be cured with anti- H pylori therapy alone. The presence of t(11;18(q21;q21 translocation is thought to predict a lower response rate to anti- H pylori treatment. Objectives To study the presence of t(11;18(q21;q21 genetic translocation and its clinical impact in low-grade gastric MALT lymphoma Brazilian patients. Methods A consecutive series of eight patients with gastric MALT lymphoma were submitted to gastroscopy, endoscopic ultrasound, histopathological examination, H pylori search and RT-PCR-based methodology. All patients received anti-H pylori treatment. Eradicated patients were followed-up every 3-6 months for 2 years. Results Eight patients were studied. All patients had tumor involvement restricted to the mucosa or submucosa and seven patients had low-grade gastric MALT lymphoma. All infected patients achieved H pylori eradication. Histological tumor regression was observed in 5/7 (71% of the low-grade gastric MALT lymphoma patients. The presence of t(11;18(q21;q21 translocation was found in 4 (57% of these patients; among them only two had histological tumor regression following H pylori eradication. Conclusions RT-PCR is a feasible and efficient method to detect t(11;18(q21;q21 translocation, being carried out in routine molecular biology laboratories. The early detection of such translocation can be very helpful for better targeting the therapy to be applied to gastric MALT lymphoma patients.

    International Nuclear Information System (INIS)

    We describe a pilot survey conducted with the Mopra 22 m radio telescope in preparation for the Millimeter Astronomy Legacy Team Survey at 90 GHz (MALT90). We identified 182 candidate dense molecular clumps using six different selection criteria and mapped each source simultaneously in 16 different lines near 90 GHz. We present a summary of the data and describe how the results of the pilot survey shaped the design of the larger MALT90 survey. We motivate our selection of target sources for the main survey based on the pilot detection rates and demonstrate the value of mapping in multiple lines simultaneously at high spectral resolution.

  3. High grade MALT lymphoma of the ileum in a child presenting as intussusception: a case report

    International Nuclear Information System (INIS)

    Lymphoma is the third most common childhood malignancy after leukemia and brain tumor. In contrast to adult non-Hodgkin's lymphoma, that occurring in children is usually found extranodally. The most common site is the abdomen, including the gastrointestinal tract, kidney and pancreas, and the next most common is the extranodal head and neck. Gastrointestinal non-Hodgkin's lymphoma in adults is usually considered to be MALT lymphoma, a distinct B-cell type, but the occurrence of this variety in the small bowel of children is relatively rate. We report a case of high-grade MALT lymphoma occurring in a nine-year-old boy who presented with ileoileal intussusception

    Metabolic dysfunction in obesity may be attenuated by whole-grain intake, which has been attributed to synergistic actions of bioactive compounds. Germination/malting may increase grain bioactives, including polyphenols, however biological effects compared with non-germinated grains are unclear. Polyphenols and biological effects were compared between malted-wheat (MLT) and whole-grain wheat (CON) breakfast cereals. Polyphenol content and antioxidant activity were significantly higher (Pobesity-related biomarkers were measured in 10 overweight/obese adults in a 2×4-week double-blind, randomised, crossover trial. Following both interventions, diastolic blood pressure reduced significantly with time (Ppolyphenols, cumulative effects in attenuating obesity-related metabolic dysfunction may require increased consumption.

    This research aimed to prepare instant flour from malted and raw (un-malted) corn flours nixtamalized by the extrusion process and evaluate the effect on the physicochemical properties of tortillas prepared using these flours. White maize was malted for 24 h, dried at 50 ± 1 °C, and ground. Subsequently, 0.3 % lime and 25 or 30 % water were added to ground malted or un-malted corn, and the mixture was refrigerated (4 °C) for 12 h. These samples were nixtamalized by an extrusion process in a single screw extruder at two temperature profiles within four heating zones, TP1 (60, 60, 70, and 80 °C) and TP2 (60, 70, 80, and 90 °C), to obtain corn flour. Water was added to the extruded corn flours to make a dough, or masa, and the masa was then molded and baked to obtain tortillas. The corn flours were characterized according to their ability to absorb water and viscosity profile (RVA). The firmness and rollability after 2 and 24 h of storage were determined, and a sensory evaluation was conducted. The malted corn flour extruded with a 25 % moisture content and TP2 temperature profile yielded tortillas with the best firmness and rollability. In conclusion, the changes during the malting of corn grain and the nixtamalization by the extrusion process improved the water absorption capacity of flours and textural properties of the tortilla and produced a product with acceptable sensory properties.

    Dan'er is a widely grown malt barley cultivar in China, but its filterability defects have severely impeded its application in beer brewing. Previous investigations have suggested that we should identify the malt filterability correlated proteins, one of which was postulated to be arabinoxylan arabinofuranohydrolase I (AXAH-I). To verify this hypothesis, we purified AXAH-I from Dan'er malt, characterised its enzyme performance, and investigated its influence on filterability by adding different amounts of purified enzyme to the mash. With 6 mU g(-1) malt AXAH-I supplemented, the wort separation rate increased by 31.8%, viscosity decreased by 3.6%, and the endosperm reserve contents declined concomitantly. Unexpectedly, the wort turbidity increased with increasing AXAH-I. We also tried to optimise the use of currently available commercial enzyme products for filterability improvement in beer brewing, by supplementing them with purified AXAH-I and β-amylase. AXAH-I could be a functional component for novel commercial enzyme products in the beer industry. PMID:25529682

    Full Text Available Em virtude da progressiva substituição dos adjuntos amiláceos pelos xaropes com alta concentração de maltose nas cervejarias brasileiras, o presente trabalho teve por objetivo comparar hidrolisados de milho e de mandioca, como adjunto de malte, na fabricação de cerveja tipo Pilsen, em escala de laboratório. Os hidrolisados foram produzidos a partir de amido de milho e fécula de mandioca, sendo que na liqüefação e sacarificação da fração amilácea destes produtos foram utilizadas, respectivamente, as enzimas comerciais Termamil (alfa amilase bacteriana e Fungamil (alfa amilase fúngica. Na fabricação das cervejas, a proporção de malte e hidrolisado foi de 2 para 1, na base do extrato. O mosto foi produzido pelo processo de infusão e após resfriamento e clarificação foi inoculado com levedura cervejeira de baixa fermentação. A fermentação transcorreu a 10 °C até 90% de atenuação do extrato aparente fermentável. As cervejas foram engarrafadas e, em seguida, maturadas a 0 °C, por 14 dias. Terminado o processo de fabricação, as cervejas foram analisadas química e sensorialmente. A semelhança na composição química dos hidrolisados de milho e de mandioca refletiu na composição química dos mostos e das cervejas. Não houve diferença estatística entre os mostos e entre as cervejas testadas para todos os parâmetros químicos analisados. Também, não existiu diferença sensorial entre as cervejas produzidas com hidrolisado de milho e hidrolisado de mandioca. Concluiu-se que a fécula de mandioca apresenta potencial de uso como matéria prima para a fabricação de xarope de maltose de uso cervejeiro e que há elevada probabilidade de sucesso no uso desse xarope para a fabricação de cervejas.The brazilians breweries replace progressively starchy adjuncts by sugary liquid adjuncts made with maize.

    Full Text Available Introduction: endoscopic ultrasonography (EUS has already proven useful in the assessment of submucosal lesions, and the staging of gastrointestinal cancer, particularly gastric MALT-type lymphoma. The goal of this paper was EUS staging. Patients and method: 24 patients (10 females, 14 males with a median age of 56 years and possibly gastric MALT lymphoma (25 cases were studied using videoendoscopy, biopsies, and echoendoscopy with 7.5- and 20-MHz radial EUS, and also with 12- and 20-MHz miniprobes (MPs. Nineteen patients were definitely evaluated (7 females, 12 males as having 20 MALT-type lymphomas, as five patients were post-hoc disregarded when an invasive, high-grade gastric lymphoma (3c or plasmocytoma (2c was subsequently demonstrated. Of these 19 patients, all had T1 lesions except for two with T2 lesions; one patient had a gastroduodenal T1 lymphoma. Echographic findings with MPs were compared to EUS (gold standard and histology both before and after eradication. Then, patients were followed up every 1-3-6 months using videoendoscopy and MPs. Results: echoendoscopy correctly identified T stages in 90% of cases. MPs identified T stages in 88% of cases, and N stages in 33% of cases, with results being slightly inferior to those obtained with conventional EUS (91 vs. 45%; they were consequently used for follow-up. After eradication, all but two patients are in complete remission and have been followed every 1-3-6 months using MPs without echographic abnormalities, except for a patient who relapsed.Introducción: la ultrasonografía endoscópica (USE ha demostrado ya su utilidad en la evaluación de las lesiones submucosas, en la estadificación del cáncer digestivo en general, y del linfoma gástrico tipo MALT en particular.

    This study examined the performance of rice and buckwheat when malted under various temperature conditions and for different lengths of time. The mashed malts produced from both rice and buckwheat contained a wide spectra of sugars and amino acids that are required for yeast fermentation, regardless of malting temperature. At the germination temperatures of 20, 25, and 30 °C used, production of reducing sugars and free amino nitrogen (FAN) followed similar patterns. This implies that temperature variations, experienced in different countries, will not have an adverse effect on the production and release of amino acids and sugars, required by yeast during fermentation, from these grains. Such consistency in the availability of yeast substrates is likely to reduce differences in processing when these malts are used for brewing. This study revealed that, while rice malt consistently produced more maltose than glucose, buckwheat malt gave several times more glucose than maltose, across all germination temperatures. Buckwheat malt also produced more soluble and free amino nitrogen than rice malt. Unlike sorghum, which has gained wide application in the brewing industry for the production of gluten-free beer, the use of rice and buckwheat is minimal. This study provides novel information regarding the potential of rice and buckwheat for brewing. Both followed similar patterns to sorghum, suggesting that they could play a similar role to sorghum in the brewing industry. Inclusion of rice and buckwheat as brewing raw materials will increase the availability of suitable materials for use in the production of gluten-free beer, potentially making it more sustainable, cheaper, and more widely available.

  20. F-18-FDG-PET in a patient with Hashimoto's thyroiditis and MALT lymphoma recurrence of the thyroid

    International Nuclear Information System (INIS)

    We report on the case of a 86-year-old male patient with a rapidly growing nodule within the right lobe of the thyroid gland, which after hemithyroidectomy, turned out to be a mucosa-associated lymphoid tissue (MALT) lymphoma of the thyroid gland. In addition, Hashimoto's thyroiditis was reported in the thyroid tissue adjacent to the MALT lymphoma. During follow-up a second nodule emerged within the left lobe and, because of evidence of MALT lymphoma recurrence, F-18-FDG-PET was performed. F-18-FDG-PET imaged a clearly in-creased accumulation within the whole left lobe and isthmus. Thus, no differences in the degree of hypermetabolism could be imaged between the nodule and the adjacent thyroid tissue. To our knowledge, this is the first report about F-18-FDG-PET in a patient with MALT lymphoma of the thyroid. Literature search revealed only a few cases of MALT lymphomas in locations other than the thyroid gland that were studied with F-18-FDG-PET. In no case was F-18 FDG accumulation seen in the MALT lesions. However, clear F-18 FDG accumulation was reported in some patients with Hashimoto's thyroiditis. It is concluded that the intensive F-18-FDG accumulation within the whole left lobe and isthmus of the presented case was due to the coexisting Hashimoto's thyroiditis. Consequently, F-18-FDG-PET imaging does not seem to be indicated in a patient with MALT lymphoma and known Hashimoto's thyroiditis in order to evaluate the status of the MALT lymphoma. (author)

    The omission of malt provides for different values of the viscosity in the wort. Various concentrations of the worts obtained this way were fermented to EtOH, and the important parameters, such as yeast cell count, acidity, EtOH assay, unfermented sugars, etc. were determined. Yeasts cultivated on beet worts under addition of (NH/sub 4/)/sub 2/SO/sub 4/, H/sub 3/PO/sub 4/, K/sub 2/CO/sub 3/, and MgSO/sub 4/, will easily ferment sugar beet worts under technical conditions to acceptable EtOH values of 11.1 dl EtOH/long ton of beets. This method was used in a plant continuously for 3 years, saving 200 long tons malt/year.

    Two einkorn wheat, one barley, three optional winter cultivation wheat and five winter cultivation wheat samples harvested in Hungary in 2011, and their malts were evaluated for their DPPH radical and ABTS radical cation scavenging activity, ferric reduction capacity (FRAP) and total phenolic content (TPC). All einkorn and barley samples exhibited significant antioxidant activities determined by DPPH and ABTS radical scavenging activities. The einkorn samples show higher polyphenol content than the other wheat samples. In all cases the barley sample had the highest antioxidant potential and polyphenol content. The einkorn malts had high DPPH and ABTS radical cation scavenging activities, but the phenolic content was lower against wheat samples. There was significant difference between the antioxidant potential of optional and winter cultivation wheat samples except on ABTS scavenging activities. Einkorn wheat is potentially a new raw material to produce organic beer that might have beneficial effects with its increased antioxidant potential. PMID:25148951

    International Nuclear Information System (INIS)

    Report a case of satisfactory progress radiation retinopathy after radiation for mucosa-associated lymphoid tissue (MALT) lymphoma. A 26-year-old male patient, referred to our department for lacrimal sac tumor. Biopsy was done by otolaryngology and radiation therapy was performed (total irradiation of 41.4 Gy) as pathological examination revealed MALT lymphoma. Soft exudates and macula edema appeared in posterior pole of the right fundus after radiotherapy. Right vision became 0.5 because of macula edema, and panretinal photocoagulation (PRP) was performed. After PRP, macula edema withdrew and right vision improved to 1.2. It is suggested that the fundus must be monitored after radiation therapy, and early treatment, such as PRP is effective in radiation retinopathy. (author)

    Lymphoma is the third most common childhood malignancy after leukemia and brain tumor. In contrast to adult non-Hodgkin's lymphoma, that occurring in children is usually found extranodally. The most common site is the abdomen, including the gastrointestinal tract, kidney and pancreas, and the next most common is the extranodal head and neck. Gastrointestinal non-Hodgkin's lymphoma in adults is usually considered to be MALT lymphoma, a distinct B-cell type, but the occurrence of this variety in the small bowel of children is relatively rate. We report a case of high-grade MALT lymphoma occurring in a nine-year-old boy who presented with ileoileal intussusception.

    Full Text Available Abstract Background MALT1 belongs to a family of paracaspase and modulates NF-κB signaling pathways through its scaffolding function and proteolytic activity. MALT1 cleaves protein substrates after a positively charged Arginine residue. BCL10, a 233 amino acids polypeptide, is identified as one of the MALT1 proteolytic substrates. MALT1 cleaves BCL10 at the C-terminal end of Arg228. A mere 5 amino acids difference between the substrate and the proteolytic product made it difficult to tell whether the cleavage event took place by using a simple western blot analysis. Here, BCL10GFP was constructed and utilized to examine the specificity and domain determinants for MALT1 cleavage in cells. Methods Various BCL10GFP constructs were transfected into HEK293T cell with MALT1 construct by using calcium phosphate-DNA precipitation method. Lysates of transfectants were resolved by SDS/PAGE and analyzed by western blot analysis. Results BCL10GFP was proteolytically processed by MALT1 as BCL10. The integrity of caspase recruitment domain (CARD and MALT1-interacting domain on BCL10 were required for MALT1 proteolytic activity. Besides the invariant P1 cleavage site Arg228, P4 Leu225 played a role in defining BCL10 as a good substrate for MALT1. Conclusions We offered a way of monitoring the catalytic activity of MALT1 in HEK293T cells using BCL10GFP as a substrate. BCL10GFP can be utilized as a convenient tool for studying the determinants for efficient MALT1 cleavage in HEK293T cells

    2006-04-01

    Polioencephalomalacia (PEM) in ruminants has been recognized as a consequence of excess sulphur intake. The present study describes clinical, gross and histopathological findings of PEM following an abrupt change of diet in two ranches housing 2750 dairy and 2300 beef cattle. As a result of severe PEM, 256 cattle died or were slaughtered. Clinical findings included circling, hypersensitivity, excessive salivation, hypermetria, incoordination, blindness and death. The first clinical signs occurred in beef calves (6-8 months old) at a holding facility. Clinical signs of the disorder continued intermittently during the 5-month period in both ranches and were more evident in calves and lactating dairy cows. The affected cattle did not respond to thiamine injections. Clinical signs disappeared gradually following removal of barley malt sprouts from the diet. Although macroscopic lesions were not apparent in the brain tissues of some animals, histopathology typical of PEM was found in most cases: spongiosis in the neuropil and neuronal necrosis, haemorrhage, capillary hyperplasia, fibrinoid degeneration in arterioles, multifocal liquefaction necroses in the grey matter and abundance of gitter cells with vacuolar large cytoplasm. Sulphide in rumen fluid of a clinically affected animal was measured as 1.55 mg/dl, which is considerably higher than that collected from two control cows (mean 0.21 mg/dl). The total sulphur content of the diet containing barley malt sprouts was estimated to be 0.45%, which is also higher than the National Research Council (NRC) maximum tolerable levels. In conclusion, PEM can result from excess barley malt sprout intake because of its higher sulphur content. Clinical signs may occur shortly after the intake of barley malt sprout as outbreaks with a higher number of deaths or as an ongoing periodic condition. PMID:16533327

    Saccharomyces cerevisiae C8-5 and Candida tropicalis F0-5 isolated from traditional sorghum beer were tested for kinetic parameters on barley malt extract, YPD (863 medium) and for alcohol production. The results showed that C. tropicalis has the highest maximum growth rate and the lowest doubling time. Values were 0.22 and 0.32 h(-1) for maximum growth rate, 3 h 09 min and 2 h 09 min for doubling time respectively on barley malt extract and YPD. On contrary, glucose consumption was the fastest with S. cerevisiae (-0.36 and -0.722 g/l/h respectively on barley malt extract and YPD). When these two yeasts were used as starters in pure culture and co-culture at proportion of 1:1 and 2:1 (cell/cell) for barley malt extract fermentation, we noticed that maltose content increased first from 12.12 g/l to 13.62-16.46 g/l and then decreased. The highest increase was obtained with starter C. tropicalis + S. cerevisiae 2:1. On contrary, glucose content decreased throughout all the fermentation process. For all the starters used, the major part of the ethanol was produced at 16 h of fermentation. Values obtained in the final beers were 11.4, 11.6, 10.4 and 10.9 g/l for fermentation conducted with S. cerevisiae, C. tropicalis, C. tropicalis + S. cerevisiae 1:1 and C. tropicalis + S. cerevisiae 2:1. Cell viability measurement during the fermentation by using flow cytometry revealed that the lowest mean channel fluorescence for FL3 (yeast rate of death) was obtained with C. tropicalis + S. cerevisiae 2:1 after 48 h of fermentation.

    A suitable ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) method was developed for the determination of 11 mycotoxins with isotope internal standard in malt. The mycotoxins in malt were extracted and purified by one-step ultrasonic extraction procedure using acetonitrile/water/acetic acid (80 : 19 : 1), and then detected and confirmed by UPLC-MS/MS, and quantified by isotope labeled AFB1 ([13C17]-AFB1) and ZEN ([13C18]-ZEN) internal standards. Rapid separation of the 11 mycotoxins was successfully achieved on a Phenomenex Kinetex C18 column (100 mm x 2.1 mm, 2.6 μm) with gradient elution using the mobile phase of methanol containing 0.1% formic acid and 2 mmol x L(-1) ammonium acetate in water. Simultaneous acquisition was performed in multiple reaction monitoring (MRM) mode with electrospray ionization (ESI) source operated in both positive and negative ionization modes. The established method provided a good linearity for the 11 mycotoxins within their respective linear ranges with correlation coefficients all higher than 0.999 1. The average recoveries ranged from 75.0% to 117.0% with relative standard deviations (RSDs) below 5.1%. The limits of detection (LODs) and quantitation (LOQs) ranged from 0.05 to 30 μg x kg(-1) and 0.15 to 87.5 μg x kg(-1), respectively, which were below the maximum residue levels (MRLs) set by the European Union. Twenty malt samples were analyzed and nine samples were detected with mycotoxins, which were confirmed according to the same fragment ions found in positive samples and the standards at the same retention time. This study has demonstrated that the one-step extraction procedure of mycotoxins from complex matrices coupled to UPLC-MS/MS method is simple, quick, accurate and sensitive for quantitative and qualitative analysis of multiple mycotoxins in malt.

  18. Long-term results of stomach-conserving therapy in gastric MALT lymphoma

    International Nuclear Information System (INIS)

    Purpose: To evaluate long-term results of stomach-conserving therapy and to assess the value of histological probable minimal residual disease (pMRD) in predicting outcome in patients with gastric MALT lymphoma. Materials and methods: We studied 115 patients with stage I-II2 gastric MALT lymphoma treated between 1975 and 2002. Initially, first-line treatment consisted of radiotherapy only. Since 1994 most patients were primarily treated with Helicobacter pylori eradication; radiotherapy was used in case of eradication failure. To assess the value of pMRD, first follow-up biopsy samples classified as compete remission (CR) according to classical clinico-pathological criteria and biopsy samples 1 year after assessment of histological CR were reviewed; results were related to outcome. Results: Following radiotherapy only (n = 56) 96% achieved a clinical CR; 10-year cancer-specific survival rate was 94%. Following H. pylori eradication only (n = 35) CR-rate was 43% and after additional treatment 89%; 5-year cause-specific survival was 93%. There was no difference in relapse rate following initial histological CR or pMRD. Conclusions: Patients with early stage gastric MALT lymphoma have a favorable long-term outcome following conservative treatment. Outcome after H. pylori eradication followed by delayed radiotherapy on indication was excellent. In our series pMRD was not associated with increased risk of recurrence

    Full Text Available Background: Butyric acid, one of the key products formed when β-glucans are degraded by the microbiota in the colon, has been proposed to be important for colonic health. Glutamine bound to the fibre may have similar effects once it has been liberated from the fibre in the colon. Both β-glucans and glutamine are found in high amounts in malted barley. Lactobacillus rhamnosus together with malt has been shown to increase the formation of butyric acid further in rats. Objective: To investigate whether Lactobacillus rhamnosus 271, Lactobacillus paracasei 87002, Lactobacillus plantarum HEAL 9 and 19, and Bifidobacterium infantis CURE 21 affect the levels of short-chain fatty acids and glutamine in caecum and portal blood of rats fed barley malt. Design: The experimental diets were fed for 12 days. The daily dose of the probiotic strain was 1×109 colony forming units and the intake of fibre 0.82 g/day. Results: The malt mostly contained insoluble fibre polymers (93%, consisting of glucose and xylose (38–41 g/kg and some arabinose (21 g/kg. The fibre polysaccharides were quite resistant to fermentation in the rats, regardless of whether or not probiotics were added (25–30% were fermented. Caecal and portal levels of acetic acid decreased in the rats after the addition of L. plantarum HEAL 9 and L. rhamnosus 271, and also the levels of butyric acid. Viable counts of Lactobacillus, Bifidobacterium and Enterobacteriaceae were unaffected, while the caecal composition of Lactobacilli was influenced by the type of strain administrated. Portal levels of glutamine were unchanged, but glycine levels increased with L. plantarum HEAL 9 and 19 and phenylalanine with L. rhamnosus 271. Conclusions: Although the probiotic strains survived and reached the caecum, except B. infantis CURE 21, there were no effects on viable counts or in the fermentation of different fibre components, but the formation of some bacterial metabolites decreased. This may be due to

    Full Text Available Kinetic simulation and drying process optimization of corn malt by Simulated Annealing (SA for estimation of temperature and time parameters in order to preserve maximum amylase activity in the obtained product are presented here. Germinated corn seeds were dried at 54-76 °C in a convective dryer, with occasional measurement of moisture content and enzymatic activity. The experimental data obtained were submitted to modeling. Simulation and optimization of the drying process were made by using the SA method, a randomized improvement algorithm, analogous to the simulated annealing process. Results showed that seeds were best dried between 3h and 5h. Among the models used in this work, the kinetic model of water diffusion into corn seeds showed the best fitting. Drying temperature and time showed a square influence on the enzymatic activity. Optimization through SA showed the best condition at 54 ºC and between 5.6h and 6.4h of drying. Values of specific activity in the corn malt were found between 5.26±0.06 SKB/mg and 15.69±0,10% of remaining moisture.Este trabalho objetivou a simulação da cinética e a otimização do processo de secagem do malte de milho por meio da técnica Simulated Annealing (SA, para estimação dos parâmetros de temperatura e tempo, tais que mantenham a atividade máxima das enzimas amilases no produto obtido.

    Our study showed that sorghum and millet followed a similar pattern of changes when they were malted under similar conditions. When the malt from these cereals was mashed, both cereal types produced wide spectra of substrates (sugars and amino acids) that are required for yeast fermentation when malted at either lower or higher temperatures. At the germination temperatures of 20, 25, and 30 °C used in malting both cereal types, production of reducing sugars and that of free amino nitrogen (FAN) were similar. This is an important quality attribute for both cereals because it implies that variation in temperature during the malting of sorghum and millet, especially when malting temperature is difficult to control, and also reflecting temperature variations, experienced in different countries, will not have an adverse effect on the production and release of amino acids and sugars required by yeast during fermentation. Such consistency in the availability of yeast food (substrates) for metabolism during fermentation when sorghum and millet are malted at various temperatures is likely to reduce processing issues when their malts are used for brewing. Although sorghum has gained wide application in the brewing industry, and has been used extensively in brewing gluten-free beer on industrial scale, this is not the case with millet. The work described here provides novel information regarding the potential of millet for brewing. When both cereals were malted, the results obtained for millet in this study followed patterns similar to those of sorghum. This suggests that millet, in terms of sugars and amino acids, can play a role similar to that of sorghum in the brewing industry. This further suggests that millet, like sorghum, would be a good raw material for brewing gluten-free beer. Inclusion of millet as a brewing raw material will increase the availability of suitable materials (raw material sustainability) for use in the production of gluten-free beer, beverages, and

    Full Text Available The study consists in the production of a traditional beer from maize in the Congo. The traditional method of brewing corn malt has three main stages: malting corn, brewing corn malt and fermentation. During the brewing corn malt, endogenous amylase activity is destroyed during the stiffening of the starch to about 80°C. A pre-cooking of the mash is necessitated to promote amylolyse at 50°C with an exogenous enzyme. The use of a preparation of α-amylase can liquefy the mash and produce a sweet wort (average density = 12.5° Balling rich in dextrin corresponding to an apparent extract of 4° Balling in beer. The rising profile of the pH of the corn malt mash, from mashing to extract the wort does not affect the pH of the beer produced. This beer, slightly alcoholic (3.6% ethanol, is characterized by a nomal acid pH (pH = 4.15 on average and a brown color (25 EBC units. Its slight bitterness (21 EBU and the fine aroma of a beer closer barley produced industrially in the Congo.

    The effects of different timing of N fertilizer application at the same rate on grain β-amylase activity, protein concentration, weight and malt quality of barley were studied. Grain β-amylase activity and protein concentration were significantly higher in treatments where all top-dressed N fertilizer was applied at booting stage only or equally applied at two-leaf stage and booting stage than in the treatment where all top-dressed N fertilizer was applied at two-leaf age stage only. On the other hand,grain weight and malt extract decreased with increased N application at booting stage. There were obvious differences between barley varieties and experimental years in the grain and malt quality response to the timing of N fertilizer application. It was found that grain protein concentration was significantly and positively correlated with β-amylase activity, but significantly and negatively correlated with malt extract and Kolbach index. The effect of grain protein concentration on malt quality was predominant over the effect of grain β-amylase activity.

Foram considerados dois tratamentos testemunha sem controle das plantas daninhas, com e sem a cultura. Nos oito demais tratamentos, a cultura esteve sempre presente, controlando-se as plantas daninhas até 10, 20, 30, 40, 50, 60, 80 e 100 dias após a emergência da cevada. A comunidade infestante da área era composta quase exclusivamente por R. .sativus. Avaliou-se o número de plantas, acúmulos de matéria seca, número médio de frutos e sementes de nabiça por planta e por unidade de área ; foram ainda avaliados o número médio de sementes por fruto, peso médio de 1.000 sementes e a contribuição das sementes na composição da matéria se catota. A análise dos resultados evidenciou que a espécie Raphanus sativus apresenta elevado potencial reprodutivo, sendo possível concluir pela ineficiência de programas de controle de curta duração, em termos de redução do banco de sementes. A presença da cultura da cevada reduziu tanto o crescimento quanto o número de sementes produzidas pela nabiça (R. sativus. Na ausência da cultura e de práticas de controle foram produzidas 5.074 sementes/m, a partir de 125 plantas/m ainda presentes na colheita da cultura.The objective of this research was to evaluate the effects of barley and weed control periods on the seed production and growth of Raphanus sativus, the major weed in the experimental area.

    The impact of malting on the profile of the phenolic compounds and the antioxidant properties of two buckwheat varieties was investigated. The highest relative increases in phenolic compounds were observed for isoorientin, orientin, and isovitexin, which are consequently major inducible phenolic compounds during malting. Only a minor relative increase was observed for the most abundant phenolic compound, rutin. The radical-scavenging activity of buckwheat seeds was evaluated using ABTS and DPPH assays. A considerable increase in total phenolic compounds and higher antioxidant activity were observed after 64h of germination, whereas kilning resulted in decreased total phenolic compounds and antioxidant activity. Higher antioxidant activities for extracts were found for buffered solvents than for pure methanol and water. Changes in the composition of the phenolic compounds and increased antioxidant content were confirmed by several methods, indicating that buckwheat malt can be used as a food rich in antioxidants.

    The genetic diversity and relationship among 40 elite barley varieties were analyzed based on simple sequence repeat (SSR) genotyping data. The amplified fragments from SSR primers were highly polymorphic in the barley accessions investigated. A total of 85 alleles were detected at 35 SSR loci, and allelic variations existed at 29 SSR loci. The allele number per locus ranged from 1 to 5 with an average of 2.4 alleles per locus detected from the 40 barley accessions. A cluster analysis based on the genetic similarity coefficients was conducted and the 40 varieties were classified into two groups. Seven malting barley varieties from China fell into the same subgroup. It was found that the genetic diversity within the Chinese malting barley varieties was narrower than that in other barley germplasm sources, suggesting the importance and feasibility of introducing elite genotypes from different origins for malting barley breeding in China.

    T-cell-receptor (TCR) signalling to NFkappaB requires the assembly of a large multiprotein complex containing the serine/threonine kinase CK1alpha, the scaffold protein CARMA1, the heterodimer BCL10-MALT1 (the CBM complex) and the IkappaB kinase complex (IKK). Although the mechanisms regulating recruitment and activation of IKK within the CBM microenvironment have been extensively studied, there is little understanding of how IKK subsequently binds and phosphorylates IkappaBalpha, the inhibitor of NFkappaB, to promote IkappaBalpha ubiquitylation and proteasomal degradation. Here, we show that BCL10, MALT1 and IKK inducibly associate with IkappaBalpha in a complex that is physically distinct from the early CK1alpha-CBM signalosome. This IkappaBalpha-containing complex probably maturates from the CBM, because siRNA-based knockdown of CARMA1, CK1alpha and BCL10 hampered its assembly, leading to a reduction in NFkappaB activation. By contrast, CK1alpha normally recruited both BCL10 and ubiquitylated species of MALT1 when IkappaBalpha levels were reduced. However, knockdown of IkappaBalpha led to an altered ubiquitylation profile of BCL10-MALT1 combined with a defect in MALT1 reorganisation within large cytoplasmic structures, suggesting that, following stimulation, IkappaBalpha might also participate in MALT1 recycling. Altogether, our data suggest a two-step mechanism to connect active IKK to IkappaBalpha, and further unveil a potential role for IkappaBalpha in resetting TCR-mediated signalling. PMID:20551178

    Full Text Available Primary non-Hodgkin’s lymphoma (NHL of the breast constitutes 0.04%-0.53% of all malignancies and 2.2% of extra nodal lymphomas. In total, 7%-8% of all B-cell lymphomas are the mucosa-associated lymphoid tissue (MALT type, of which up to 50% of primary gastric MALT lymphoma. Herein we present a patient with breast MALT lymphoma that transformed to diffuse large B-cell lymphoma (DLBCL. A 69-year-old female presented with a mass on her left breast. Physical examination showed a 3 × 3-cm mass located 1 cm from the areola on the upper lateral quadrant of the breast at the 1 o’clock position, which was fixed and firm. Excisional biopsy was performed and pathologic examination of the specimen showed MALT lymphoma transformation to DLBCL. The patient was staged as II-EA. The rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP protocol was scheduled as treatment. Following 6 courses of R-CHOP, 2 additional courses of rituximab were administered. Positron emission tomography (PET-CT was done at the end of the treatment. PET showed that the patient was in complete remission. At the time this report was written, the patient was being followed-up at the outpatient clinic on a regular basis. Lymphoma of the breast is a rarity among malignant tumors of the breast. The most common type of lymphoma is DLBCL. Breast MALT lymphoma is extremely rare. Primary MALT lymphoma of the breast can transform from low grade to high grade and recurrence is possible; therefore, such patients should be monitored carefully for transformation.

    Full Text Available The change in the content of nitrogenous substances in the process of malting grain of the two varieties of spring wheat (Triticum aestivum L., grown in the Primorye Territory and containing differing levels of proteins in the grain was evaluated. It is shown that higher protein wheat transferred more nitrogen materials to the roots and shoots and this results to significant loss of nitrogen compounds in the endosperm and germ. Increase of germination term decreases the weight of grain due to loss of breath, which in turn increases the concentration of crude protein in the grain.

    The biosorption of orange solimax TGL 182% (OS-TGL) textile dye onto new and low cost biossorbent (malt bagasse) in aqueous solutions was investigated. The malt bagasse was characterized by Fourier transform infrared spectroscopy and specific surface area (BET method).Batch biosorption experiments were conducted in order to determine the following parameters: particles size, pH, agitation speed, temperature, contact time, biomass dosage, influence of the ionic strength and, finally, the influence of other textile dye on the OS-TGL biosorption. The optimum conditions for OS-TGL removal were obtained at pH 1.5, agitation speed of 150rpm, contact time of 180min and biomass dosage 2, 8gL(-1). The results show that the kinetics of biosorption followed a pseudo-second-order model and by increasing the temperature from 293 up to 313K, the biosorption capacity was improved. The Langmuir model showed better fit and the estimated biosorption capacity was 23.2mgg(-1). The negative values of Gibbs free energy, ΔG°, and positive value of enthalpy, ΔH°, confirm the spontaneous nature and endothermic character of the biosorption process. The results of the ionic strength effect indicated that the biosorption process under study had a strong tolerance in high salt concentrations. The removal capacity (>95%) was not affected with the presence of other textile dyes. PMID:26590694

    Full Text Available Applicability of electrophoretic separations of albumins/globulins, followed by nonspecific protein staining and specific glycoprotein and aminopeptidase detection has been examined for barley variety discrimination. Albumins/globulins extracted from dry grains and green malt of six barley varieties were separated by polyacrylamide gel electrophoresis (10 % T, pH=8.9 of native and sodium dodecyl sulfate denatured proteins, and by isoelectric focusing in pH gradient of 3.5-9.5 and 4.0-6.5. Analysis of dry grain extracts gave better results than green malt extracts. Obtained data indicate that SDS-PAGE of albumins/globulins and IEF in pH gradient 3.5-9.5 followed by Coomassie Blue staining could be useful in Croatian barley variety discrimination. Angora barley could be clearly distinguished from the other varieties which were grouped as follows: Rodnik/Sladoran, Barun/Rex, and Martin. Glycoprotein patterns did not improve the recognition of individual varieties. Broad specificity, phenylalanine and leucine preferring, and arginine specific aminopeptidase were not found as applicable markers for discrimination of examined barley varieties.

    Caspases are intracellular proteases that are best known for their function in apoptosis signaling.It has become evident that many caspases also function in other signaling pathways that propagate cell proliferation and inflammation,but studies on the inflammatory function of caspases have mainly been limited to caspase-1-mediated cytokine processing.Emerging evidence,however,indicates an important contribution of caspases as mediators or regulators of nuclear factor-κB(NF-κB)signaling,which plays a key role in inflammation and immunity.Much still needs to be learned about the mechanisms that govern the activation and regulation of NF-κB by caspases,and this review provides an update of this area.Whereas apoptosis signaling is dependent on the catalytic activity of caspases,they mainly act as scaffolding platforms for other signaling proteins in the case of NF-κB signaling.Caspase proteolytic activity,however,counteracts the pro-survival function of NF-κB by cleaving specific signaling molecules.A striking exception is the paracaspase mucosa-associated lymphoid tissue 1(MALT1),whose adaptor and proteolytic activity are both needed to initiate a full blown NF-κB response in antigen-stimulated lymphocytes.Understanding the role of caspases and MALT1 in the regulation of NF-κB signaling is of high interest for therapeutic immunomodulation.

    2016-03-01

    Paracaspases and metacaspases are two families of caspase-like proteins identified in 2000. Up until now paracaspases were considered a single gene family with one known non-metazoan paracaspase in the slime mold Dictyostelium and a single animal paracaspase called MALT1. Human MALT1 is a critical signaling component in many innate and adaptive immunity pathways that drive inflammation, and when it is overly active, it can also cause certain forms of cancer. Here, we report the identification and functional analysis of two new vertebrate paracaspases, PCASP2 and PCASP3. Functional characterization indicates that both scaffold and protease functions are conserved across the three vertebrate paralogs. This redundancy might explain the loss of two of the paralogs in mammals and one in Xenopus. Several of the vertebrate paracaspases currently have incorrect or ambiguous annotations. We propose to annotate them accordingly as PCASP1, PCASP2, and PCASP3 similar to the caspase gene nomenclature. A comprehensive search in other metazoans and in non-metazoan species identified additional new paracaspases. We also discovered the first animal metacaspase in the sponge Amphimedon. Comparative analysis of the active site suggests that paracaspases constitute one of the several subclasses of metacaspases that have evolved several times independently. PMID:26377317

The optimum formula was galanga, garlic, long pepper, licorice, and black pepper at the ratio of 0.5:8:1:4:1,respectively. Previously, waste paddy has been used directly as a renewable resource for fuel ethanol production using solidstate fermentation (SSF with Loog-pang. In this study, hydrolyzed malted rice starch was used as the sole nutrient source insubmerged fermentation (SmF to enhance the process yield. The maximum ethanol productivity (4.08 g/kg waste paddy h-1and the highest ethanol concentration (149±7.0 g/kg waste paddy were obtained after 48 hrs of incubation. The resultsindicated that starch saccharification provided a higher ethanol yield (48.38 g/100g sugar consumed than SSF. In addition,the efficiency of ethanol fermentation was 67% which is similar to that of the malted rice made from normal paddy (68%.This result suggests that waste paddy could be used as an alternative raw material for ethanol production.

    MALT (Micro Analysis Laboratory, Tandem accelerator, The University of Tokyo) was designed for a 'highly sensitive and precise elemental and isotopic microanalysis system' using an ion-beam generated by a Pelletron™ 5UD tandem accelerator. Currently, a multi-nuclide AMS (10Be, 14C, 26Al, 36Cl, 129I) system is available and shows good performance in both precision and sensitivity, and the accelerator serves for PIXE, NRA, ERDA/RBS measurements as well. The total operation time of the accelerator has been over 95,000 hours since the start of MALT, 20 years ago. After the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, many projects related to 129I have been conducted. The retrospective reconstruction of the 131I distribution at the accident from 129I is one of the most important missions for dose evaluation of the residents. The accident-derived 129I is also quite useful as a tracer for the general iodine dynamics in the environment. As a new tool for environmental assessment related to nuclear activity, including the global fallout from past atmospheric nuclear bomb testing, effects from the spent fuel reprocessing plant, and nuclear accidents such as Chernobyl and FDNPP, a 236U-AMS system is now under development.

  1. Malting process optimization for protein digestibility enhancement in finger millet grain.

    Science.gov (United States)

    Hejazi, Sara Najdi; Orsat, Valérie

    2016-04-01

    Finger millet (Eleusine coracana) is a nutritious, gluten-free, and drought resistant cereal containing high amounts of protein, carbohydrate, and minerals. However, bio-availability of these nutrients is restricted due to the presence of an excessive level of anti-nutrient components, mainly phytic acid, tannin, and oxalate. It has been shown that a well-designed malting/germination process can significantly reduce these anti-nutrients and consequently enhance the nutrient availability. In the present study, the effects of two important germination factors, duration and temperature, on the enhancement of in-vitro protein digestibility of finger millet were thoroughly investigated and optimized. Based on a central composite design, the grains were germinated for 24, 36, and 48 h at 22, 26, and 30 °C. For all factor combinations, protein, peptide, phytic acid, tannin, and oxalate contents were evaluated and digestibility was assessed. It was shown that during the malting/germinating process, both temperature and duration factors significantly influenced the investigated quantities. Germination of finger millet for 48 h at 30 °C increased protein digestibility from 74 % (for native grain) up to 91 %. Besides, it notably decreased phytic acid, tannin, and oxalate contents by 45 %, 46 %, and 29 %, respectively. Linear correlations between protein digestibility and these anti-nutrients were observed. PMID:27413219

    Full Text Available The effects of malting and fermentation on some physical properties and microbiological composition and safety of maize/sesame food formulations were investigated. Malted and fermented maize flours were blended with defatted sesame flour, by material balancing, to give four food formulations (Unmalted maize + defatted sesame (UMS, malted maize + defatted sesame (MMS, un-malted fermented maize + defatted sesame (UFMS and malted fermented maize + defatted sesame (MFMS, which all contained 16 g protein and 9 g fat/100 g food. Viscosity, functional properties and microbiological composition of flours and gruels from the food formulations were evaluated using standard methods of analysis. Malting and fermentation significantly (p<0.05 decreased gruel viscosities from 318.00 to 210.70 cP, packed bulk density from 1.08 to 0.97 g/mL and swelling index from 4.43 to 2.93 mL/g; while increasing water absorption capacity from 3.30 to 4.07 g/g and reconstitution index from 5.02 to 6.13 mL/g in UMS and MFMS samples respectively. Total viable counts, yeasts and moulds all increased significantly (p<0.05 with malting and fermentation. Enterobacteriaceae and Staphylococcus species were predominant in the non-fermented products, while yeast dominated in the fermented products, whose gruels also inhibited growth of Staphylococcus in challenge tests.

    Phenol-specific extracts of 12 Belgian special beers were analyzed by gas chromatography hyphenated to olfactometry (AEDA procedure) and mass spectrometry (single ion monitoring mode). As guaiacol and 4-methylphenol were revealed to be more concentrated in brown beers (>3.5 and >1.1 μg/L, respectively), they are proposed as specific markers of the utilization of dark malts. Analysis of five differently colored malts (5, 50, 500, 900, and 1500 °EBC) allowed confirmation of high levels of guaiacol (>180 μg/L; values given in wort, for 100% specialty malt) and 4-methylphenol (>7 μg/L) for chocolate and black malts only (versus respectively beer aging highlighted major differences between phenols. Guaiacol and 4-methylphenol appeared even more concentrated in dark beers after 14 months of aging, reaching levels not far from their sensory thresholds. 4-Vinylphenols and 4-ethylphenols, on the contrary, proved to be gradually degraded in POF(+)-yeast-derived beers. Vanillin exhibited an interesting pattern: in beers initially containing Beers initially showing an above-threshold level of vanillin displayed a decrease during aging. PMID:25174984

  8. Gastric lymphoma of mucosa associated lymphoid tissue (MALT) type: longterm treatment results

    International Nuclear Information System (INIS)

    Objective: In recent years, a large proportion of non-Hodgkin's lymphomas of the stomach are recognized as low grade tumors of the mucosa associated lymphoid tissue (MALT) type. Since the MALT morphological subtype has only gained acceptance as a malignant lymphoma after the establishment of the Working Formulation, there is limited information about its natural history, disease pattern, and longterm treatment outcome. This study is an analysis of these parameters in patients with primary MALT lymphoma of the stomach. Materials and Methods: Consecutive patients with primary gastric MALT lymphoma who received definitive treatment at the Massachusetts General Hospital between (4(78)) and (2(95)) were included in the study. The diagnosis was pathologically verified in all cases. Clinical staging studies included chest X-ray +/- chest CT, abdomino-pelvic CT or bipedal lymphangiogram, barium swallow, and bone marrow biopsy. Treatment strategies included combinations of partial or total gastrectomy, radiation (RT) and chemotherapy (chemo). RT was given via multifield technique, with 10-25MV photons, to doses of 36-50.4 Gy (1.1-1.8 Gy per fraction, 5 days a week). Survival analyses were performed by the Kaplan-Meier actuarial method. Results: There were twenty-two patients between the ages of 45 - 93 years, with a mean follow-up of 67 months. Ten were male and 12 female. The most frequent presenting symptoms were epigastric pain (77%), dyspepsia (65%), and melena (41%). The mean duration of symptoms was 27 months. Eighteen cases were clinical stage (cs)I, two csII, one csIII, and one csIV. The treatment approaches were: 1) csI:6 gastrectomy alone, 7 gastrectomy and RT, 1 gastrectomy and chemo, 2 RT alone, 1 chemo and RT, 1 no therapy; 2) csII: 2 gastrectomy and RT; 3) csIII: 1 gastrectomy and chemo; 4) csIV: 1 chemo and RT. Among 16 gastrectomy specimens, multifocal gastric involvement was evident in 50%. The most frequently involved sites were the body (63%) and antrum

    Activation of the Escherichia coli malEp promoter relies on the formation of a higher order structure involving cooperative binding of MalT to promoter-proximal and promoter-distal sites as well as CRP binding to three sites located in between. MalT is the primary activator and one function of CRP is to facilitate cooperative binding of MalT to its cognate sites by bending the intervening DNA. It is shown here that CRP also participates directly in malEp activation. This function is carried o...

It can be used in existing engines. Biodiesel consists of fatty acid alkyl esters. Conversion of triglycerides to biodiesel fuel is commonly achieved through a series of transesterification reactions involving the reaction of an alkoxy group of an ester (i.e., mono-, di-, or triglyceride) with that of a small alcohol (usually methanol). This reaction is traditionally catalyzed by homogeneous catalysts, such as bases or mineral acids. Basic catalysts have been proved to be much more active than acidic ones. However, due to environmental (waste water) and economic concerns (catalyst separation and product and by-product cleaning), heterogeneous catalysts are much more desirable. In the present study we have evaluated the use of biochar, produced from malt spent rootlets, as a potential basic catalyst, for transesterification of triglycerides using triacetin as a probe molecule. The biochar used in this study was prepared by heating malt spent rootlets in an oxygen-limited environment. It is a carbon rich material, containing 66% C, 22% O, 0.45% Mg, 0.86% Si, 5.7% K, 1.5% Cl, 0.61% Ca, and 2.4% P. Aqueous suspension of this material equilibrates at pH= 10. This is probably due to high K content. Furthermore, it exhibits high specific surface area (SSA= 183 m2g-1). The above described characteristics make this material very promising catalyst for

El método DRIS fue un buen indicador del balance nutricional de la planta y de la respuesta a la fertilización nitrogenada.The wider use of malting barley with high yield potential will necessarily increase soil nutrient requirements, the resulting nutritional deficiency placing constraints on production. The Diagnosis and Recommendation Integrated System (DRIS approach uses leaf nutrient relationships to rank the importance of different nutrients in limiting crop yield. The objectives of the present study were to: a evaluate the sensitivity of the DRIS methodology in detecting responses to nitrogen (N fertilizer; b establish the ranking of the main macronutrient requirements; and c determine whether N application improves the nutrient balance in plants. Malting barley plants were taken from fertilizer experiments carried out in 1999 and 2000 and sampled at the tillering and heading stages. At tillering, N was found to be the most deficient nutrient in the control and fertilized plots and S in cases where N was more abundant (fertilized with 30 or 60 kg N ha-1. The Nutritional Balance Index (IBN and N:S ratio show a slight nutritional imbalance at this stage. At the heading stage the plants showed significant N deficiency, followed in many cases by S deficiency, directly affecting yield parameters. No P and K deficiencies were registered in the soils. In 1999, yields were low and showed fertilization response except in Alberti, where nitrate availability and yields were high. In 2000, higher water availability gave rise to higher yields with marked deficiencies in N owing to the shortage of N availably at sowing. S alternated with N in the order of requirements and IBN values decreased with increasing N availability. There was an 87% and 68% correlation between this index and the yields of the control and fertilized plots, respectively. The DRIS approach proved a good

  14. CHEMICAL EVOLUTION IN HIGH-MASS STAR-FORMING REGIONS: RESULTS FROM THE MALT90 SURVEY

    International Nuclear Information System (INIS)

    The chemical changes of high-mass star-forming regions provide a potential method for classifying their evolutionary stages and, ultimately, ages. In this study, we search for correlations between molecular abundances and the evolutionary stages of dense molecular clumps associated with high-mass star formation. We use the molecular line maps from Year 1 of the Millimetre Astronomy Legacy Team 90 GHz (MALT90) Survey. The survey mapped several hundred individual star-forming clumps chosen from the ATLASGAL survey to span the complete range of evolution, from prestellar to protostellar to H II regions. The evolutionary stage of each clump is classified using the Spitzer GLIMPSE/MIPSGAL mid-IR surveys. Where possible, we determine the dust temperatures and H2 column densities for each clump from Herschel/Hi-GAL continuum data. From MALT90 data, we measure the integrated intensities of the N2H+, HCO+, HCN and HNC (1-0) lines, and derive the column densities and abundances of N2H+ and HCO+. The Herschel dust temperatures increase as a function of the IR-based Spitzer evolutionary classification scheme, with the youngest clumps being the coldest, which gives confidence that this classification method provides a reliable way to assign evolutionary stages to clumps. Both N2H+ and HCO+ abundances increase as a function of evolutionary stage, whereas the N2H+ (1-0) to HCO+ (1-0) integrated intensity ratios show no discernable trend. The HCN (1-0) to HNC(1-0) integrated intensity ratios show marginal evidence of an increase as the clumps evolve

    Primary hepatic lymphomas are rare tumors. We report a case of a 72 year-old woman with a past history of colonic adenocarcinoma who presented primary hepatic lymphoma of MALT-type. The patient had been operated on 3 years before for colonic adenocarcinoma, pT3N0, revealed by a bowel obstructive syndrome. She had been treated by chemotherapy for 6 months. During the follow-up, the computed tomography-scan (CT-scan) revealed the presence of a not well-demarcated mass in segment III of the liver, measuring 4 cm in diameter. The tumor was hypodense and was not enhanced on dynamic study. The mass was already present on the initial CT-scan. Left lobectomy was performed with the diagnosis of liver metastasis of the colonic adenocarcinoma. Surgical specimen showed a tumor composed of a dense infiltrate of small lymphocytes positive for B-cell markers on immunohistochemistry. The tumor contained reactive lymphoid follicles and there were numerous lympho-epithelial biliary lesions. The patient is alive and free of disease 2 years after the diagnosis. Primary hepatic lymphoma of MALT-type is a low-grade B cell lymphoma. Twenty-five cases had been reported in the literature so far. The patients were 16 females and 9 males, mean age 63.5 years. The pathogenesis is still unclear but half of the patients had a past history of chronic inflammatory liver disease (hepatitis B or C virus infection, ascaris infection, primary biliary cirrhosis) or malignant neoplasm. This tumor has a good prognosis; it is usually limited to the liver and surgical resection cures the patient in most cases. PMID:16246295

    Full Text Available In food industry, especially among the brewers, using of natural ingredients is increasingly growing demand. Beer is one of the most popular beverages in the world with evident positive effects on the overall health condition. It can be used as a base for developing a variety of products with specific physiological activity. Bee pollen is considered to be one of the possible sources of active ingredients for that purpose. Activity of phenolic and flavonoid compounds in bee pollen can contribute to the antioxidant potential of beer. The objective of this study was to examine the influence of different types and content of bee pollen on the antioxidant properties of malt beverages and to compare phenolic and flavonoid profiles. The technological process of malt beverages preparation with addition of bee pollen was also verified. It was found out that all beverages enriched with bee pollen had higher polyphenol, flavonoid content and antioxidant potential than control sample – pure wort. The higher antioxidant activities of all extracts was measured in sample R2 - wort with 0.6% of dry rapeseed pollen and sample R4 - wort with 0.6% of frozen rapeseed pollen. The higher phenolic content than in other samples was measured in sample M4 - wort with 0.6% of frozen poppy pollen and sample M1 - wort with 0.256% of dry poppy pollen. Higher total flavonoid content was found out in sample M2 - wort with 0.6% of dry poppy pollen and M4 - wort with 0.6% of frozen poppy pollen. In conclusion, the most noticeable results of antioxidant activity, phenolic and flavonoid content were achieved in samples with higher 0.6% addition of bee pollen, mostly poppy (Papaver somniferum L. pollen.

    2015-08-01

    Full Text Available A simple and reliable method for the simultaneous determination of nine phenolic compounds in barley and malted barley was established, using liquid chromatography-diode array detection-electrospray ionization tandem mass spectrometry (HPLC-DAD-ESI-MS/MS. The phenolic compounds can be easily detected with both systems, despite significant differences in sensitivity. Concentrations approximately 180-fold lower could be achieved by mass spectrometry analysis compared to diode array detection, especially for the flavan-3-ols (+-catechin and (−-epicatechin, which have poor absorptivity in the UV region. Malt samples were characterized by higher phenolic content comparing to corresponding barley varieties, revealing a significant increase of the levels of (+-catechin and (−-epicatechin during the malting process. Moreover, the industrial malting is responsible for modification on the phenolic profile from barley to malt, namely on the synthesis or release of sinapinic acid and epicatechin. Accordingly, the selection of the malting parameters, as well as the barley variety plays an important role when considering the quality and antioxidant stability of beer.

    Eight two-rowed barley cultivars were grown at seven locations in the southern winter-barleyzone of China. Mean grain β-glucanase activity ranged from 39.89 U kg-1 for Suyin2 to 49.75 U kg-1 for Xi-umai3 in 8 cultivars grown at 7 locations, and from 38.74 U kg-1 in Zhengzhou to 57. 96 U kg-1 in Putianamong 7 locations on an average of all cultivars. Correspondingly, mean malt β-glucanase activity of 8 culti-vars ranged from 313.33 U kg-1 for ZAU3 to 489.89 U kg-1 for Daner Barley, and of 7 locations from 330.40U kg-1 in Yancheng to 418.24 U kg-1 in Putian. There were significant differences among cultivars and loca-tions in malt β-glucanase activities. The locations showed much larger variation in malt β-glucanase activitiesthan cultivars. The reduction of total β-glucan content after malting varied in both cultivars and locations,with a mean of 78.31%. The analysis of correlations showed that malt β-glucan content was significantly posi-tively and negatively correlated with grain β-glucan content and malt β-glucanase activity, respectively, andmalt β-glucanase activity was significantly positively correlated with grain β-glucanase activity.

    As a major component of non-starch polysaccharide in barley, arabinoxylan (AX) plays an important role in quality traits of malt and the final beer product. The Chinese barley malt has encountered filterability problems for a long time. The main reason caused by barley cultivar has been accepted in the malting and brewing industries. In our previous proteomic study, the peroxidase (POD) BP1 was found to be in quite high abundant in the filterability defect Chinese barley malt. Therefore, the present study tried to verify its negative effect on filterability, by surveying its activity in different malt samples and detecting effects of POD on AX gelation and filterability. The results showed that the activity of POD, as well as the content of AX bounded ferulic acid, were both negatively correlated with filterability, while the feruloyl esterase activity was positively correlated with it. In addition, AX gelation catalyzed by POD caused worse filterability, and the natural inhibitor of POD, vitamin C, could blocked the cross linking catalyzed by POD and thus improve the filterability. These results all suggested the great negative effect of POD on malt filterability. PMID:26616970

    Barley malt, a product of controlled germination, has been shown to produce high levels of butyric acid in the cecum and portal serum of rats and may therefore have anti-inflammatory effects. The aim of the study was to investigate how four barley malts, caramelized and colored malts, 50-malt and 350-malt, differing in functional characteristics concerning beta-glucan content and color, affect short-chain fatty acids (SCFA), barrier function and inflammation in the hindgut of rats fed high-fat diets. Male Wistar rats were given malt-supplemented high-fat diets for four weeks. Low and high-fat diets containing microcrystalline cellulose were incorporated as controls. All diets contained 70 g kg(-1) dietary fiber. The malt-fed groups were found to have had induced higher amounts of butyric and propionic acids in the hindgut and portal serum compared with controls, while cecal succinic acid only increased to a small extent. Fat increased the mRNA expression of tight junction proteins and Toll-like receptors (TLR) in the small intestine and distal colon of the rats, as well as the concentration of some amino acids in the portal plasma, but malt seemed to counteract these adverse effects to some extent. However, the high content of advanced glycation end-products (AGE) in caramelized malt tended to prohibit the positive effects on occludin in the small intestine and plasma amino acids seen with the other malt products. In conclusion, malting seems to be an interesting process for producing foods with positive health effects, but part of these effects may be destroyed if the malt contains a high content of AGE.

    The effect of removing the second step of malt conversion in the brewing of Chibuku beer was investigated with the intention of extending the shelf-life of the product. Chibuku was brewed in the laboratory scale fermenters using Delta Beverages' standard brewing procedure. A variation was made where the second malt conversion was not conducted on one brew. The effect of increasing pasteurisation time was also investigated. The extension of shelf-life was determined by following the physicochemical and the sensory profile of the products for a period of ten days under sub-tropical ambient conditions. Ethanol productions were similar between the control and test beers (without second conversion malt). A product with overall acceptability of 70% was made from the brew without the second malt conversion and with 15 min pasteurisation at 80 degrees C. The product was, however, low in bite and head retention, but had less bacterial load, decreased acid production, and improved keeping quality by at least two days. However, due to contamination of the pitching yeast with lactic acid bacteria (LAB), total acids rapidly increased after 168 h and caused unacceptable sourness. Increasing pasteurisation time to 20 min reduced bacterial load of the wort to figures as low as 2 x 10(3) cfu/ml. General hygiene levels of the brewery were acceptable and no coliforms were detected in the product or contact surfaces along the production line. Bacterial contamination of the product mainly comes from the raw materials with pasteurisation greatly reducing this load. If improved, the procedure has the potential of extending the shelf-life of the beer to beyond 168 h. PMID:19162356

    Cancer diagnosis can be a complex process, which takes consideration of histopathological, clinical, immunophenotypic, and genetic features. Since non-random chromosomal translocations are specifically involved in the development of various cancers, the detection of these gene aberrations becomes increasingly important. In recent years, break-apart (or split-signal) fluorescence in situ hybridization (FISH) has emerged as an advantageous technique to detect gene translocations on tissue sections. However, FISH assays are technically challenging and require specialized fluorescence microscopes. Furthermore, the FISH signal is not stable for long term archiving due to photo bleaching. Our objective was to demonstrate the feasibility of brightfield break-apart in situ hybridization (ba-ISH) for anaplastic lymphoma kinase (ALK) and mucosa-associated lymphoid tissue translocation protein 1 (MALT1) genes as models. ALK or MALT1 break-apart probes were labeled with digoxigenin (DIG) or 2,4-dinitrophenyl (DNP) on both sides of a known gene breakpoint region and the hybridization sites were visualized with the combination of alkaline phosphatase (AP)-based blue and red detection. Therefore, normal genes are detected as purple dots by mixing blue and red colors while translocated genes are detected as isolated blue or red dots. Formalin-fixed, paraffin-embedded tonsil was used as control for the co-localized 5' and 3' probes. Gene translocations of ALK or MALT1 were detected as separate blue and red dots on ALCL and MALT lymphoma cases. Thus, ISH analyses of gene translocations can be conducted with a regular light microscope and the long term archiving of break-apart ISH slides can be achieved. PMID:20621192

  13. Treatment and prognosis of primary gastric B-cell lymphoma. Special Reference to therapeutic strategy of MALT lymphoma

    International Nuclear Information System (INIS)

    To evaluate the influence of therapeutic methods on the prognosis of primary gastric B-cell lymphoma, we analyzed the prognostic factors for 322 patients, comprised of 186 with low-grade mucosa-associated lymphoid tissue (MALT) lymphoma, 54 with diffuse large B-cell lymphoma (DLBL) plus MALT lymphoma, and 82 with DLBL without MALT lymphoma. Among them, the clinical course of 96 patients who were treated by Helicobacter pylori eradication was also evaluated. Patients who underwent stomach-conserving treatment (H. pylori eradication, chemotherapy or radiation; n=100) showed a better overall survival probability than those treated by surgery (n=222), but the progression-free probability did not differ between the two groups. After H. pylori eradication, complete remission was achieved in 55 patients, of whom histologic relapse was observed in 4 patients (7%). Second line treatment for 34 patients, who failed to respond to eradication therapy, including oral monochemotherapy with cyclophosphamide, radiation, CHOP (CHOP; cyclophosphamide, doxorubicin, vincristine, prednisolone) chemotherapy, and gastrectomy resulted in complete remission in 29 patients (85%). These results suggest stomach- conserving treatment to be an optimal therapeutic modality for primary gastric B-cell lymphoma. (author)

    A method for discriminating malting barley varieties based on direct matrix-assisted laser desorption-ionisation - time-of-flight mass spectrometry (MALDI-TOF MS) fingerprinting of proteins was developed. Signals corresponding to hordeins were obtained by simple mixing of powdered barley grain with a MALDI matrix solution containing 12.5mgmL(-1) of ferulic acid in an acetonitrile:water:formic acid 50:33:17 v/v/v mixture. Compared to previous attempts at MALDI-TOF mass spectrometric analysis of barley proteins, the extraction and fractionation steps were practically omitted, resulting in a significant reduction in analytical time and costs. The discriminatory power was examined on twenty malting barley varieties and the practicability of the method was tested on sixty barley samples acquired from Pilsner Urquell Brewery. The method is proposed as a rapid tool for variety assignment and purity determination of malting barley that may replace gel electrophoresis currently used for this purpose. PMID:27041307

    Biochar is receiving increased attention as a promising material in environmental applications. It is obtained from the incomplete combustion of carbon-rich biomass under oxygen-limited conditions. One of the many proposed applications of biochars is the removal of metals (e.g., lead, mercury, etc.) from aqueous solutions. Mercury is one of the heavy metals of particular concern due to its toxicity even at relatively low concentration and thus, its removal from aqueous systems is desirable. Malt spent rootlets is a by-product formed during beer production, it is inexpensive and it is produced in high quantities. The objective of the present study was to evaluate the potential use of biochar, produced from malt spent rootlets, to remove mercury from aqueous solutions. Batch experiments were conducted at room temperature (25oC) to obtain the optimum sorption conditions under different pH values, biomass dose, contact time, and solution ionic strength. Sorption kinetics and equilibrium capacity constants were determined at the optimum pH value. Furthermore, the effect of different leaching solutions on mercury desorption from the biochar was examined. All studies with mercury and biochar were conducted at pH 5 that was determined to be the optimum pH for sorption. The proportion of mercury removal increased with the increased dose of the biochar, i.e. from 71% removal for biochar dose of 0.3 g/L, it reached almost 100% removal for biochar dose ˜1 g/L. Based on the isotherm data, the maximum biochar sorption capacity (qmax) for mercury was 99 mg/g. Based on the sorption kinetic data, (qmax) was achieved after 2 h; it should be mentioned that 30% of the (qmax) was observed within the first 5 min. Five leaching solutions were tested for mercury desorption (H2O, HCl, EDTA, NaCl and HNO3). HCl resulted in the highest extraction percentage of the sorbed mercury. The desorbing mercury percentages at 24 h for HCl concentrations 0.1, 0.2, 0.4, 0.8, and 2 M were 62, 59, 62, 69

    Patient and Method: A 56-year old woman was first treated in August 1990 for a low-grade B-cell lymphoma in the conjunctiva of the left eyelid. 42 months later an extranodal B-cell lymphoma, located in the conjunctiva of the right eyelid, was found. After a father period of 48 months a MALT-type lymphoma arose in the supraglottic larynx. The findings of staging examinations were normal. The final diagnosis was low-grade B-cell lymphoma of the MALT-type, limited to the conjunctival eyelids and supraglottic larynx, with the clinical staging of IE A. Treatment consisted of a LASER-resection followed by a locoregional radiotherapy, with the dose of 40 Gy. Results: Currently no evidence of disease (NED) at all sites can be proven. Conclusions: Extranodal, primary low grade B-cell MALT-type lymphoma are rare. In the literature only few cases of each larynx- and conjunctival eyelid involvment described. The radiotherapy has been reported to achieve a long time of relapse-free intervall. The present case demonstrates, that even the recurrence of an extranodal, primary low-grade B-cell MALT-type lymphoma responds well to local radiotherapy and can also have a long period of no evidence of disease.

    Full Text Available The manuscript presents a detailed description of the meteorological and chemical code of Malte – a model to predict new aerosol formation in the lower troposphere. The aerosol dynamics are achieved by the new developed UHMA (University of Helsinki Multicomponent Aerosol Model code with kinetic limited nucleation as responsible mechanism to form new clusters. First results indicate that the model is able to predict the on- and offset of new particle formation as well as the total aerosol number concentrations that were in good agreement with the observations. Further, comparison of predicted and measured H2SO4 concentrations showed a satisfactory agreement. The simulation results indicated that at a certain transitional particle diameter (2–9 nm, organic molecules can begin to contribute significantly to the growth rate compared to sulphuric acid. At even larger particle sizes, organic molecules can dominate the growth rate on days with significant monoterpene concentrations. The intraday vertical evolution of newly formed clusters and particles in two different size ranges resulted in two maxima at the ground and the top of the mixed layer with higher concentrations for the detectable particles above 3 nm below in contrast to the predicted cluster concentrations.

    One of the purposes to employ modern technologies in agricultural and food industry is to increase the efficiency and automation of production processes, which helps improve productive effectiveness of business enterprises, thus making them more competitive. Nowadays, a challenge presents itself for this branch of economy, to produce agricultural and food products characterized by the best parameters in terms of quality, while maintaining optimum production and distribution costs of the processed biological material. Thus, several scientific centers seek to devise new and improved methods and technologies in this field, which will allow to meet the expectations. A new solution, under constant development, is to employ the so-called machine vision which is to replace human work in both quality and quantity evaluation processes. An indisputable advantage of employing the method is keeping the evaluation unbiased while improving its rate and, what is important, eliminating the fatigue factor of the expert. This paper elaborates on the topic of quality evaluation by marking the contamination in malting barley grains using computer image analysis and selected methods of artificial intelligence [4-5].

    Full Text Available One of the most important biological substances consumed in insufficient quantity is fibre that is often deficient in the diet. In general, dietary fibre is edible part of plants, or similar carbohydrates, that are resistant to digestion and absorption in the small intestine. Nowadays, there are many sources of fibre available for bakery industry, whether through addition of non-traditional bread cereals or through isolated form as additives. Except to supposed increase the nutritional value of bakery products with added fiber and raw materials containing fiber is necessary to think about their technological quality and rheological properties of dough. The aim of this experimental work was to investigate the effect of the addition of selected polysaccharides (inulin, Potex - potato fiber and non-bakery crops (naked barley, malt containing significant polysaccharides used in the mixture with wheat flour type T-650 in different ratios on the basis of farinographic evaluations. Based on the results of rheological measurements we found out that quality of dough was deteriorating proportionally to the amount of used additives. On the other hand, positively could be considered the increase of water absorption with addition of Potex and naked barley.

  2. Low-grade MALT lymphoma of the stomach: a review of treatment options

    International Nuclear Information System (INIS)

    Purpose: Low-grade mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach (MLS) is often associated with the presence of Helicobacter pylori (H. pylori) bacteria. Eradication of the infection with antibiotic therapy may result in regression of the lymphoma. But when antibiotic treatment fails to reverse the malignant process or if H. pylori is absent, other treatment options should be considered. Because MLS is often confined to the stomach and regional lymph nodes, it is potentially curable with local therapy. Endoscopy and improved imaging, with endoscopic ultrasound (EUS) and computerized tomography (CT), have reduced the prior dependence on surgery for diagnosis and staging of gastric lymphomas. Methods and Results: This review details the advances in the diagnosis, classification, and imaging of MLS. We also describe the experience that supports the use of radiation therapy as the preferred treatment of MLS in patients who have not responded to antibiotic therapy or have not had evidence for H. pylori infection. Conclusions: Radiation therapy for MLS is not only effective and safe, but offers the significant advantage of low morbidity and gastric function preservation

    T-2 and HT-2 toxins are two of the most toxic members of type-A trichothecenes, produced by a number of Fusarium species. The occurrence of these mycotoxins was studied in barley samples during a survey carried out in the 2011-2014 growing seasons in climatically different regions in Italy. The percentage of samples found positive ranges from 22% to 53%, with values included between 26 and 787 μg/kg. The percentage of samples with a T-2 and HT-2 content above the EU indicative levels for barley of 200 μg/kg ranges from 2% to 19.6% in the 2011-2014 period. The fungal species responsible for the production of these toxins in 100% of positive samples has been identified as Fusarium langsethiae, a well-known producer of T-2 and HT-2 toxins. A positive correlation between the amount of F. langsethiae DNA and of the sum of T-2 and HT-2 toxins was found. This is the first report on the occurrence of F. langsethiae-and of its toxic metabolites T-2 and HT-2-in malting barley grown in Italy. PMID:27556490

  4. Selective C-Rel activation via Malt1 controls anti-fungal T(H-17 immunity by dectin-1 and dectin-2.

    Directory of Open Access Journals (Sweden)

    Sonja I Gringhuis

    Full Text Available C-type lectins dectin-1 and dectin-2 on dendritic cells elicit protective immunity against fungal infections through induction of T(H1 and T(H-17 cellular responses. Fungal recognition by dectin-1 on human dendritic cells engages the CARD9-Bcl10-Malt1 module to activate NF-κB. Here we demonstrate that Malt1 recruitment is pivotal to T(H-17 immunity by selective activation of NF-κB subunit c-Rel, which induces expression of T(H-17-polarizing cytokines IL-1β and IL-23p19. Malt1 inhibition abrogates c-Rel activation and T(H-17 immunity to Candida species. We found that Malt1-mediated activation of c-Rel is similarly essential to induction of T(H-17-polarizing cytokines by dectin-2. Whereas dectin-1 activates all NF-κB subunits, dectin-2 selectively activates c-Rel, signifying a specialized T(H-17-enhancing function for dectin-2 in anti-fungal immunity by human dendritic cells. Thus, dectin-1 and dectin-2 control adaptive T(H-17 immunity to fungi via Malt1-dependent activation of c-Rel.

  9. Non-surgical treatment for localized gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Interium analysis of a multicenter prospective study in Japan

    International Nuclear Information System (INIS)

    Although eradication of Helicobacter pylori and radiation therapy (RT) have curative potential for gastric mucosa-associated lymphoid tissue (MALT) lymphoma, no prospective study has yet been reported. This prospective study evaluated the efficacy and safety of this non-surgical treatment for localized gastric MALT lymphoma. Among the 115 eligible patients, 89 (77.3%) achieved remission with eradication therapy. Twenty five (21.7%) patients received RT as additional treatment for residual tumor and 22 (88%) achieved complete remission. No serious adverse events, such as hemorrhage or perforation of the stomach, were observed. This organ-preserving treatment for localized gastric MALT lymphoma is safe and effective and has the potential to become the standard treatment for this disease, although long-term follow up is necessary.

    Primary marginal zone B-cell MALT-type lymphomas of the uterine corpus are exceedingly rare entities, with only 6 cases reported in the literature to date. We present the additional case of a 70-yr-old white woman who underwent a laparoscopic total hysterectomy with bilateral salpingo-oophorectomy for an asymptomatic ovarian cyst. At microscopic examination, endometrial samples showed a dense, nodular lymphocytic infiltrate, suggestive of a lymphoproliferative disorder. Morphology, immunohistochemistry, and molecular analysis supported the diagnosis of MALT-type lymphoma of the endometrium. Benign reactive conditions, such as endometritis and other small B-cell lymphomas were ruled out. Moreover, we investigated the pathogenesis of our case, focusing on Chlamydia trachomatis infection, chromosomal translocations affecting the NF-kB pathway, and discussing the role of autoimmunity in the development of MALT-type lymphomas.

    Mucosa-associated lymphoid tissue (MALT) type lymphoma arises from extranodal marginal zone B-cell. It is etiologically associated with Helicobacter pylori infection and, hence, can be cured by antibiotic treatment. MALT type lymphoma is the most common variety of gastric lymphoma that is rare in the stomach). The published data of clinical studies on the usefulness of 18F-FDG PET in the diagnosis of MALT type lymphoma varied according to authors. Thus, the result of Hoffmann et al. was discouraging whereas a high diagnostic accuracy was reported by Ambrosini et al. The latter group further went to suggest that higher 18F-FDG uptake in gastric MALT type lymphoma would positively relate to the aggressiveness of neoplasm. The clinical studies conducted by other groups on MALT lymphomas of the stomach, lung, orbit and parotid gland and the stomach, lung, parotid gland, skin, orbit, mandible, esophagus and uterus confirmed that 18F-FDG scan is valuable.

  12. Treatment Outcome of Mucosa Associated Lymphoid Tissue (MALT) Marginal Zone Non-Hodgkin's Lymphoma. Single Institutional Experience

    International Nuclear Information System (INIS)

    To evaluate the treatment outcome in patients with mucosa associated lymphoid tissue (MALT) lymphoma in terms of response to treatment, progression-free and overall survivals as well as prognostic factors. Patients and Methods: Between 1995 and 2002,40 patients with clinical stages (CS) I-IV MALT lymphoma were treated at NEMROCK. The progression free survival (PFS) and overall survival (OAS) were calculated using the Kaplan Meier technique. Thirty-one patients (77.5%) had CS I-II and 9 (22.5%) had CS III-IV disease. Twenty of the 31 CS I-II patients received radiation therapy alone, five patients received chemotherapy, while three patients were treated by triple therapy (Amoxicillin, Omeperazole, Clarithromycin). Among the 9 CS III-IV patients, treatment included chemotherapy alone (6 patients), chemo radiation (2 patients) and surgery (one patient). The median followup period was 40 months. 19 out of twenty patients with CS I-II treated by radiation therapy alone had a 95% response rate (CR 85% - PR 10%). Among the study population (40 patients), the 5 year OAS and PFS were 86% and 66%, respectively. The 5 year OAS was 86% and PFS was 72% among CS III patients; the corresponding estimates in CS III-IV patients were 70% and 28%, respectively. Using multivariate analysis, there was a significant correlation between the stage of the disease, site of presentation (non GIT) and the overall survival. Modest doses of radiation therapy provide better local control in patients with early stage MALT lymphoma. The poor PFS in advanced staged disease suggests the need for further clinical trials evaluating novel drug approaches taking into consideration the biological behavior and the indolent nature of such disease entity

    Full Text Available Malnutrition of varying degrees has been associated with feeding infants with unwholesome and poor quality complementary foods. Therefore, the aim of this study was to produce complementary foods from quality protein maize (QPM using the processes of malting and fermentation. The resulting flour was blended with processed soy bean flour at a ratio of 70:30 (maize: soybean. The nutritional qualities of the complementary foods were assessed biologically using animal feeding experiment to determine the growth rate, feed intake, protein quality parameters, haematological properties and rehabilitation potentials. The results showed that the protein efficiency ratio (PER and food efficiency ratio of the malted QPM fortified with soybean were 2.44 and 0.24, respectively, which was the highest among the formulated diets and compared favourably with casein (2.5 and commercial diet (2.3. The QPM-based diets had a better biological value (<60% and true dig stibility (<60% than the products from normal maize. The packed cell volume of the samples ranged between 23.00 (basal and 46.00% (soy fermented normal maize. The QPM-based diets enhanced the quick recovery of protein starved/depleted animals better than the NM-based diets. Moreover, the addition of soybean further boosted the ability of the diet to rehabilitate the animals. The best result was seen in the group of rats fed with soy-malted QPM. The use of QPM in complementary food formulation gave better results and could alleviate the problem of protein and energy malnutrition, thereby reducing the mortality rate among infants.

    A number of hydrolyzing enzymes that are secreted from malt during brewing, including cell wall-hydrolyzing, saccharide-hydrolyzing, protein-degrading, lipid-hydrolyzing, and polyphenol and thiol-hydrolyzing enzymes, are expected to exist in an active form in waste from beer fermentation broth (WBFB). In this study, the existence of these enzymes was confirmed by sodium dodecyl sulfate polyacrylamide gel electrophoresis, after which enzyme extract was partially purified through a series of purification steps. The hydrolyzing enzyme activity was then measured under various conditions at each purification step using carboxymethyl cellulose as a substrate. The best hydrolyzing activities of partially purified enzymes were found at pH 4.5 and 50 °C in a citrate buffer system. The enzymes showed highest thermal stability at 30 °C when exposed for prolonged time. As the temperature increased gradually from 25 to 70 °C, yeast cells in the chemically defined medium with enzyme extract lost their cell wall and viability earlier than those without enzyme extract. Cell wall degradation and the release of cell matrix into the culture media at elevated temperature (45-70 °C) in the presence of enzyme extract were monitored through microscopic pictures. Saccharification enzymes from malt were relatively more active in the original WBFB than supernatant and diluted sediments. The presence of hydrolyzing enzymes from malt in WBFB is expected to play a role in bioethanol production using simultaneous saccharification and fermentation without the need for additional enzymes, nutrients, or microbial cells via a cell-free enzyme system.

    The aim of this work was to characterize physicochemical, thermal and rheological properties of starches isolated from malting barley varieties. The analyzed starches contained 19.6-25.2 g of amylose, 42.47-70.67 mg of phosphorus, 0.50-1.26 g of protein and 0.10-0.61 g of fat per 100 g of starch dry mass. The clarity of the 1 % (w/w) starch pastes ranged from 5.4 to 9.8 %. Values of the characteristic gelatinization temperatures were in the ranges of 56.5-58.5 °C, 61.2-63.0 °C and 66.7-68.7 °C, respectively for TO, TP and TE, whereas values of gelatinization enthalpy were from 6.49 to 9.61 J/g. The barley starches showed various tendency to retrogradation, from 24.52 to 44.22 %, measured as R = ∆HR/∆HG value. The pasting curves showed differences in pasting characteristics of the barley starches, where values of peak (PV) and final (FV) viscosities were 133-230 mPa·s and 224-411 mPa·s, respectively. The barley starch pastes exhibited non-Newtonian, shear thinning flow behaviour and thixotropy phenomenon. After cooling the starch gels showed different viscoelastic properties, however, most of them behaved like weak gels (tan δ = G″/G' > 0.1). Significant linear correlations between the parameters of pasting characteristic and some rheological parameters were found. PMID:26243900

  16. A case of cardiac cancer diagnosed after 30 Gy radiation therapy for gastric mucosa-associated lymphoid tissue (MALT) lymphoma without helicobacter pylori (H. pylori) infection

    International Nuclear Information System (INIS)

    An 80-year-old man was referred to Shinshu University Hospital in April 2001 for treatment of gastric mucosa-associated lymphoid tissue (MALT) lymphoma. He had received anti-biotic therapy in spite of no evidence of H. pylori infection in the former hospital 3 years ago, but no remarkable improvement was recognized and endoscopic findings were progressive. An esophagogastroduodenoscopy (EGD) revealed mucosal redness on the greater curvature and the anterior wall of the body. Biopsy specimens taken from the lesions showed remarkable infiltration of atypical small lymphocytes, and this lesions were diagnosed MALT lymphoma by an immunophenotypic studies. Endoscopic ultrasonography (EUS) showed that MALT lymphoma was limited within the mucosa and submucosa. Staging work up revealed stage I. After written informed consent, he was treated by 30 Gy radiation therapy for gastric MALT lymphoma. Response assessment was performed by EGD, EUS, and biopsy specimens, and a complete remission was confirmed. After that, he was followed up with regular intervals, and EGD was performed every 6 months. He was diagnosed to have O I type cardiac cancer at 21 months after radiation therapy. He underwent proximal partial gastrectomy, and histopathological findings showed as follows: O I type, 17 x 12 mm, tub 2, SM, ly 1, v 1, n 0, PM (-), DM (-), INFγ, stage I A. No residual lesion of gastric MALT lymphoma and no dysplasia of gastric mucosa was recognized. Causal relationship between radiation therapy and carcinogenesis in this case is unclear. However, it might be suggested by the facts that cancer occurred in the radiation field where MALT lymphoma had been presented and gastric cancer was rare in the stomach without H. pylori infection.

    AIM: A high percentage of early-stage high-grade gastric mucosa-associated lymphoid tissue (MALT) lymphomas remain Helicobacter pylori(H pylori)-dependent. However,unlike their low-grade counterparts, high-grade gastric MALT lymphomas may progress rapidly if unresponsive to H pylori eradication. It is mandatory to identify markers that may predict the H pylori-dependent status of these tumors. Proliferation of MALT lymphoma cells depends on cognate help and cell-to-cell contact of H pylori-specific intratumoral T-cells. To examine whether the expression of co-stimulatory marker CD86 (B7.2) and the infiltration of CD56 (+) natural killer (NK) cells can be useful markers to predict Hpylori-dependent status of high-grade gastric MALT lymphoma.METHODS: Lymphoma biopsies from 26 patients who had participated in a prospective study of H pylori-eradication for stage IE high-grade gastric MALT lymphomas were evaluated. Tumors that resolved to Wotherspoon grade Ⅱ or less after H pylorieradication were classified as H pyloridependent; others were classified as H pylori-independent.The infiltration of NK cells and the expression of CD86 in pre-treatment paraffin-embedded lymphoma tissues were determined by immunohistochemistry.RESULTS: There were 16 H pylori-dependent and 10H pylori-independent cases. CD86 expression was detected in 11 (68.8%) of 16 Hpyiori-dependent cases but in none of 10 Hpylori-independent cases (P = 0.001).H pylori-dependent high-grade gastric MALT lymphomas contained significantly higher numbers of CD56 (+) NK cells than H pylori-independent cases (2.8±1.4% vs 1.1±0.8%; P = 0.003). CD86 positive MALT lymphomas also showed significantly increased infiltration of CD56 (+)NK cells compared to CD86-negative cases (2.9±1.1% vs1.4±1.3%; P= 0.005).CONCLUSION: These results suggest that the expression of co-stimulatory marker CD86 and the increased infiltration of NK cells are associated with H pylori-dependent state of early-stage high-grade gastric MALT

Samples were divided into two groups; IBDV infected group (21, 24 and 30 days old and control group (non infected birds; 21 days old. Haematoxylin and eosin stained slides were prepared for microscopic studies to observe the distribution and the number of lymphocytes in the mucosa of the digestive tract and respiratory system. Lymphocytes were significantly (P<0.05 lower in proventriculus, duodenum, jejunum, ileum, cecum, cecal tonsils and lungs of IBDV infected chickens than the control. Moreover, the reduction in lymphocytes number was maximum in duodenum and cecal tonsils, while minimal in lungs. Depletion of lymphocyte was mainly in the lamina propria and the core of the villi and depletion increased with the advance of age of IBDV infected chicken. These results demonstrate that IBDV destroys the lymphocytes of the MALT and suppresses the immunity.

    This study aimed to achieve the conversion of cereal proteins to the alternative end products glutamate or γ-aminobutyrate (GABA). Rye malt, fungal proteases, and lactobacilli were employed to convert wheat gluten or barley proteins. Glutamate and GABA formations were strain-dependent. Lactobacillus reuteri TMW1.106 and Lactobacillus rossiae 34J accumulated glutamate; L. reuteri LTH5448 and LTH5795 accumulated GABA. Glutamate and GABA accumulation by L. reuteri TMW1.106 and LTH5448 increased throughout fermentation time over 96 h, respectively. Peptides rather than amino acids were the main products of proteolysis in all doughs, and barley proteins were more resistant to degradation by rye malt proteases than wheat gluten. However, addition of fungal protease resulted in comparable degradation of both substrates. Glutamate and GABA accumulated to concentrations up to 63 and 90 mmol kg(-1) DM, respectively. Glutamate levels obtained through bioconversion of cereal proteins enable the use of hydrolyzed cereal protein as condiment. PMID:21271723

    This study quantified antiotensin I-converting enzyme (ACE) inhibitory peptides in rye malt sourdoughs supplemented with gluten proteins and fermented with six strains of Lactobacillus spp. Bioinformatic analysis of prolamins from barley, rye, and wheat demonstrated that the ACE inhibitory peptides LQP, LLP, VPP, and IPP are frequently encrypted in their primary sequence. These tripeptides were quantified by liquid chromatography-tandem mass spectrometry. Tripeptide levels in sourdoughs were generally higher as compared to the chemically acidified controls. Sourdoughs fermented with different strains showed different concentrations of LQP and LLP. These differences corresponded to strain-specific differences in PepO and PepN activities. The highest levels of peptides VPP, IPP, LQP, and LLP, 0.23, 0.71, 1.09, and 0.09 mmol (kg DM)(-1), respectively, were observed in rye malt: gluten sourdoughs fermented with Lactobacillus reuteri TMW 1.106 and added protease. These concentrations were 6-7 times higher as compared to sourdough without fungal protease and exceed the IC(50) by 100-1000-fold. PMID:21985248

    Finger millet (Elucine corocana), locally known as ragi, and probiotics have been recognized for their health benefits. In the present work we describe novel probiotic ragi malt (functional food) that has been prepared using ragi and probiotic Leuconostoc mesenteroides (Lm) and Bacillus subtilis natto (Bs), alone and in combination, for antagonistic activity against Vibrio cholerae (Vc). In vitro studies using pure cultures showed that each probiotic strain (Lm or Bs) was able to inhibit the planktonic growth of Vc as well as its ability to make biofilms and adhere to extracellular matrix proteins (fibronectin, Fn) that may function in vivo as initial ports of entrance of the pathogen. Interestingly, the combination of both probiotic strains (Lm plus Bs) produced the strongest activity against the Vc. When both cultures were used together in the ragi malt the antimicrobial activity against Vc was enhanced due to synergistic effect of both probiotic strains. The inclusion of both probiotic strains in the functional food produced higher amounts of beneficial fatty acids like linoleic and linolenic acid and increased the mineral content (iron and zinc). The viability and activity of Lm and Bs against Vc was further enhanced with the use of adjuvants like ascorbic acid, tryptone, cysteine hydrochloride and casein hydrolysate in the ragi malt. In sum, the intake of probiotic ragi malt supplemented with Lm and Bs may provide nutrition, energy, compounds of therapeutic importance and antagonistic activity against Vc to a large extent to the consumer.

Results indieate that adding the malt extract to wheat dough changes the theological characteristics of dough and improves the performance in bread baking. The sensory evaluation proves that the bread quality is improved by a proper addition of malt extract, especially the bread taste, flavor and inner textural structure. Furthermore, the stale rate of bread is reduced and bread quality assurance period is extended by the malt extract addition. The optimum addition dose of the maltextract in bread produetion is 60% substitution amount of sugar.

    Full Text Available Abstract Background The B cell antigen receptor (BCR and pathogen recognition receptors, such as Toll-like receptor 4 (TLR4, act in concert to control adaptive B cell responses. However, little is known about the signaling pathways that integrate BCR activation with intrinsic TLR4 stimulation. Antigen receptors initialize activation of the inducible transcription factor nuclear factor-κB (NF-κB via recruitment of the membrane-associated guanylate kinase caspase recruitment domain protein 11 (CARD11, the adapter molecule B cell CLL/lymphoma 10 (BCL10, and the "paracaspase" mucosa-associated lymphoid tissue lymphoma translocation gene 1 (MALT1 into lipid rafts. Upon BCR triggering, this activation strictly depends on BCL10, but not on MALT1, leading to the hypothesis that a MALT1-independent NF-κB activation pathway contributes to BCR-induced NF-κB activation downstream of BCL10. The identity of this pathway has remained elusive. Results Using genetic and biochemical approaches, we demonstrate that the IRAK4- and IRAK1-dependent TLR signaling branch is activated upon BCR triggering to induce partial NF-κB activation. BCR-induced MALT1-independent IκB degradation and B cell proliferation were inhibited in MALT1/IRAK4 double knockout B cells. Moreover, IRAK1 was recruited into lipid rafts upon BCR stimulation and activated following transient recruitment of IRAK4. Conclusion We propose that the observed crosstalk between BCR and TLR signaling components may contribute to the discrimination of signals that emanate from single and dual receptor engagement to control adaptive B cell responses.

    Purpose To determine whether in patients with extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue lymphoma (MALT), delayed–time-point 2-18F-fluoro-2-deoxy-d-glucose-positron emission tomography (18F-FDG-PET) performs better than standard–time-point 18F-FDG-PET. Materials and Methods Patients with untreated histologically verified MALT lymphoma, who were undergoing pretherapeutic 18F-FDG-PET/computed tomography (CT) and consecutive 18F-FDG-PET/magnetic resonance imaging (MRI), using a single 18F-FDG injection, in the course of a larger-scale prospective trial, were included. Region-based sensitivity and specificity, and patient-based sensitivity of the respective 18F-FDG-PET scans at time points 1 (45–60 minutes after tracer injection, TP1) and 2 (100–150 minutes after tracer injection, TP2), relative to the reference standard, were calculated. Lesion-to-liver and lesion-to-blood SUVmax (maximum standardized uptake values) ratios were also assessed. Results 18F-FDG-PET at TP1 was true positive in 15 o f 23 involved regions, and 18F-FDG-PET at TP2 was true-positive in 20 of 23 involved regions; no false-positive regions were noted. Accordingly, region-based sensitivities and specificities were 65.2% (confidence interval [CI], 45.73%–84.67%) and 100% (CI, 100%-100%) for 18F-FDG-PET at TP1; and 87.0% (CI, 73.26%–100%) and 100% (CI, 100%-100%) for 18F-FDG-PET at TP2, respectively. FDG-PET at TP1 detected lymphoma in at least one nodal or extranodal region in 7 of 13 patients, and 18F-FDG-PET at TP2 in 10 of 13 patients; accordingly, patient-based sensitivity was 53.8% (CI, 26.7%–80.9%) for 18F-FDG-PET at TP1, and 76.9% (CI, 54.0%–99.8%) for 18F-FDG-PET at TP2. Lesion-to-liver and lesion-to-blood maximum standardized uptake value ratios were significantly lower at TP1 (ratios, 1.05 ± 0.40 and 1.52 ± 0.62) than at TP2 (ratios, 1.67 ± 0.74 and 2.56 ± 1.10; P = 0.003 and P = 0.001). Conclusions Delayed–time-point imaging

  8. Exposure to Glycolytic Carbon Sources Reveals a Novel Layer of Regulation for the MalT Regulon

    2011-01-01

    Full Text Available Bacteria adapt to changing environments by means of tightly coordinated regulatory circuits. The use of synthetic lethality, a genetic phenomenon in which the combination of two nonlethal mutations causes cell death, facilitates identification and study of such circuitry. In this study, we show that the E. coli ompR malTcon double mutant exhibits a synthetic lethal phenotype that is environmentally conditional. MalTcon, the constitutively active form of the maltose system regulator MalT, causes elevated expression of the outer membrane porin LamB, which leads to death in the absence of the osmoregulator OmpR. However, the presence and metabolism of glycolytic carbon sources, such as sorbitol, promotes viability and unveils a novel layer of regulation within the complex circuitry that controls maltose transport and metabolism.

    Full Text Available Abstract CD5-positive marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT of the lung is very rare. An 82-year-old Japanese woman was found to have an abnormal lung shadow on chest X-ray photography, and was admitted to our hospital. Imaging modalities including X-ray photography, computed tomography, and magnetic resonance imaging showed a small (2 × 1 × 1 cm opacity of the right upper lobe. Transbronchial lung biopsy was performed. It showed severe proliferation of small lymphocytes. The small lymphocytes were centrocytes-like, and minor plasma cell differentiation was recognized. Lymphoepithelial lesions were scattered. Immunohistochemically, the tumor cells were positive for CD5, CD20, CD43, CD45, CD79α, bcl-2, and κ-chain, but negative for CD2, CD3, CD10, CD21, CD23, CD35, CD45RO, CD56, IgA, IgG, IgM, IgD, λ-chain, TdT, and cyclin D1. The Ki-67 labeling was 10%. CD3-positive and CD45RO-positive inflammatory T-cells were scattered in small amount. The pathological diagnosis was CD5-positive marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT of the lung. The patient was treated with chemotherapy (CHOP: cyclophosphamide, hydroxydaunorbicin, vincristine, and predonisone, and the lung tumor disappeared. The patient is now free of the lymphoma 10 years after the first manifestation.

    cultivo para estimar niveles de contaminación por arsénico.The contamination by arsenic in water and ground of Zimapán, Hidalgo, Mexico, causes that malt barley (Hordeum distichon L. grown in this region, accumulates this element. The objective was to measure the levels of arsenic accumulated in organs and tissues of barley under controlled conditions, at different stages of development. Malt barley cv. Esmeralda was grown in 25 pots, five pots per differentiated trial. Trials include negative (not contaminated ground and water and positive controls. Five plants by pot were used and the accumulation of arsenic in each one was evaluated in five organs: root, stem, leaf, glean and grain, at each of five stages of development (coleoptiles formation or first leaf, macollo or true leaves from an armpit first knot that becomes present separated from the ground and forms the first spike, formation of spikes and seed filling. A random block design with three treatments was used: with arsenic, positive control and negative control. Malt barley presented high accumulation of arsenic at different stages of development, directly proportional to the time of exposition. Roots presented the highest accumulation of arsenic (100 and 300 mg kg-1, followed by leaves (80 to 180 mg kg-1 and stem (70 to 110 mg kg-1. The level of accumulation of arsenic in grains was between 40-90 mg kg-1, amount that according to Argentinean norms can be considered as highly contaminated. For the bioaccumulation index (BI, the leaves presented the high values, classified as medium values (0.1-1 for green plants. This organ can be indicative of contamination level in the ground. The largest values for the BI were observed in the stem, this organ can be a malt barley specific indicator of the level of arsenic contamination.

    2016-04-01

    In beer, 3-deoxyglucosone (3-DG) and 3-deoxygalactosone (3-DGal) are important sugar degradation products, but little is known about the relevance of the interconversion reaction between these compounds in different types of beer. In the present study, 3-DG was quantitated at concentrations of 12.9-52.7 mg/L and 3-DGal at concentrations of 6.0-26.4 mg/L in different types of beer (pilsner, wheat, bock, dark, and alcohol-free beers). The concentrations in malt beer tended to be higher. Largely overlapping concentration ranges precluded a classification of beers by their 3-deoxyglycosone contents. 3,4-Dideoxyglucoson-3-ene (3,4-DGE) was identified as an important intermediate and quantitated in beer and malt beer for the first time. The E and Z isomers of the corresponding quinoxaline were synthesized by a new synthetic approach and isolated by semipreparative HPLC. An assay was developed for quantitation of (E)- and (Z)-3,4-DGE by HPLC-MS/MS, and the Z isomer was determined at concentrations of 0.3-1.7 mg/L in beer and 0.5-4.8 mg/L in malt beer samples. The E isomer was shown to be of little importance. Concentrations of 5-hydroxymethylfurfural (HMF) were twice as high as those of (Z)-3,4-DGE in beer samples (0.4-3.7 mg/L) but much higher in malt beer samples (1.6-336 mg/L). PMID:26984557

  14. Effect of malt pretreatment and fermentation on anti-nutritional factors and mineral bioavailability of pearl millet (Pennisetum glaucum L.)

    International Nuclear Information System (INIS)

    pearl millet (pennisetum glaucum L.) is a source of carbohydrate, protein and minerals that is comparable to other common cereal grains. However, anti nutrient factors like phytate and polyphenols reduce nutrient bioavailability which can be improved by suitable processing methods such as germination and fermentation with and without malt pretreatment. In this study of 8 pearl millet cultivars Ashana, Dahabaya, Dembi, GB-87-35, Kordofani, Madelkawaya, population 1Shambat and Ugandi were investigated. Results showed that pearl millet contained 7.7-8.9% moisture, 1.6-23% ash, 11.4-13.0% protein, 4.0-7.7% oil and 2.1-3.2% crude fiber. Mineral contents were 13.0-19.4, 370.0-547.5, 70.3-93.3, 49.1-61.9 and 551.0-1290.4 mg/100 g for Na,K,Mg, Ca and P respectively and 1.3-1.8, 7.5-11.7, 0.8-1.7, 0.5-1.5 and 0.062-0.103 mg/100 g for Zn, Fe, Mn, Cu and Co respectively. HCI-extractability of these minerals (an index of their bioavailability to humans) were 63.1-73.3% Na, 64.9-73.3% K, 55.7-61.4% mg, 27.7-88.3% Ca, 31.0-38.5% P, 41.2-45.9% Zn, 22.5-27.7% Fe, 44.3-48.8% Mn, 21.3-28.6% Cu and 85.3-88.6% CO. Phytic acid content ranged from 422.3-1101.0 mg/100 g and polyphenol ranged from 306.7-669.4 mg/100 g. Cooking caused slight increase in mineral content and significantly (p<0.01) improved the bioavailability of all the minerals investigated; phytic acid reduced by 6-10% and polyphenols by 6-8%. Germination for 2,4 and 6- days showed significant (P<0.01) differences in the concentration of minerals during the course of germination.Total content of Fe, Zn and Mn were increased significantly (P<0.01) for all cultivars. The bioavailability of all the minerals was significantly (P<0.01) improved throughout all the time intervals of germination. Phytic acid was reduced by 66.3-81.0% after 6- days of germination while polyphenol content was reduced by 34.3-44.0%. Fermentation of cultivars of : Ashana and Dembi affected the minerals content and significantly (P<0.01) improved the

  15. Long-time follow-up study of localized gastric mucosa-associated lymphoid tissue (MALT) lymphoma and the clinical features of antibiotic-resistant cases of gastric MALT lymphoma

    International Nuclear Information System (INIS)

    To clarify the clinical features of gastric mucosa-associated lymphoid tissue (MALT) lymphoma (GML) with persistent lymphoma after eradication therapy of Helicobacter pylori (H. pylori), and the outcome of long-time follow-up study after treatment against GML, seventy-six patients with localized GML were studied. The median follow-up period was 44.4 months. Thirty-eight of 49 patients (77.6%) with H. pylori-positive GML had been cured of GML by antibiotic therapy alone. On the other hand, none of 13 patients with H. pylori-negative GML had been cured by antibiotic therapy (77.6% vs 0%, p<0.001). ''H. pylori-negative'' is one of the clinical features of antibiotic-resistant cases with GML. There was no significant difference in sex, age, stage, endoscopic finding, depth, and affected region between the two groups of cured and persistent GML with H. pylori infection. Twenty-two of 29 patients (75.6%) with antibiotic-resistant or H. pylori-negative cases of GML had been cured by 30 Gy radiation therapy. Low-dose radiation was thought to be a useful therapeutic procedure as a second line treatment'' of localized GML. (author)

    Massive star-forming regions with observed infall motions are good sites for studying the birth of massive stars. In this paper, 405 compact sources have been extracted from the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) compact sources that also have been observed in the Millimetre Astronomy Legacy Team 90 GHz (MALT90) survey during Years 1 and 2. These observations are complemented with Spitzer GLIMPSE/MIPSGAL mid-IR survey data to help classify the elected star-forming clumps into three evolutionary stages: pre-stellar, proto-stellar and UCHII regions. The results suggest that 0.05 g cm$^{-2}$ is a reliable empirical lower bound for the clump surface densities required for massive-star formation to occur. The optically thick HCO$^{+}$(1-0) and HNC(1-0) lines, as well as the optically thin N$_{2}$H$^{+}$(1-0) line were used to search for infall motions toward these sources. By analyzing the asymmetries of the optically thick HCO$^{+}$(1-0) and HNC(1-0) lines and the mapping observations of HC...

    AIM To report 3 of 120 patients on the German MALT lymphoma trial with H. pYlori-associated gastric MALT Iymphoma who developed early gastric cancer 4 and 5 years, after complete Iymphoma remission following cure of H. pylori infection.PATIENTS AND RESULTS Three patients (two men, 74 and 70 years; one women, 77 years)with H. pylori -associated low-grade MALTlymphoma achieved complete lymphoma remission after being cured. Surveillance endoscopies were performed twice a year in accordance to the protocol. Four years aftercomplete lymphoma remission in two patients,and after 5 years in the other, early gastric adenocarcinoma of the mucosa-type, type Ⅱ a and type Ⅱ c, respectively, was detetcted,which were completely removed by endoscopic mucosa resection. in one patient, the gastric cancer was diagnosed at the same location as the previous. MALT lymphoma, in the other patients it was detected at different sites of the stomach distant from location of the previous MALT lymphoma. The patients were H. pylori negative during the whole follow-up time.CONCLUSION These findings strengthen the importance of regular long-term follow-up endoscopies in patients with complete remission of gastric MALT lymphoma after cure of H.pylori infection. Furthermore, gastric adenocarcinoma may develop despite eradication of H. pylori.

  18. A MALT90 study of the chemical properties of massive clumps and filaments of infrared dark clouds

    2014-02-01

    Context. Infrared dark clouds (IRDCs) provide a useful testbed in which to investigate the genuine initial conditions and early stages of massive-star formation. Aims: We attempt to characterise the chemical properties of a sample of 35 massive clumps of IRDCs through multi-molecular line observations. We also search for possible evolutionary trends among the derived chemical parameters. Methods: The clumps are studied using the MALT90 (Millimetre Astronomy Legacy Team 90 GHz) line survey data obtained with the Mopra 22 m telescope. The survey covers 16 different transitions near 90 GHz. The spectral-line data are used in concert with our previous LABOCA (Large APEX BOlometer CAmera) 870 μm dust emission data. Results: Eleven MALT90 transitions are detected towards the clumps at least at the 3σ level. Most of the detected species (SiO, C2H, HNCO, HCN, HCO+, HNC, HC3N, and N2H+) show spatially extended emission towards many of the sources. Most of the fractional abundances of the molecules with respect to H2 are found to be comparable to those determined in other recent similar studies of IRDC clumps. We found that the abundances of SiO, HNCO, and HCO+ are higher in IR-bright clumps than in IR-dark sources, reflecting a possible evolutionary trend. A hint of this trend is also seen for HNC and HC3N. An opposite trend is seen for the C2H and N2H+ abundances. Moreover, a positive correlation is found between the abundances of HCO+ and HNC, and between those of HNC and HCN. The HCN and HNC abundances also appear to increase as a function of the N2H+ abundance. The HNC/HCN and N2H+/HNC abundance ratios are derived to be near unity on average, while that of HC3N/HCN is ~10%. The N2H+/HNC ratio appears to increase as the clump evolves, while the HNC/HCO+ ratio shows the opposite behaviour. Conclusions: The detected SiO emission is probably caused by shocks driven by outflows in most cases, although shocks resulting from the cloud formation process could also play a role

    Full Text Available Abstract Background elicobacter pylori infection is associated with several gastro-duodenal inflammatory diseases of various levels of severity. To determine whether certain combinations of genetic markers can be used to predict the clinical source of the infection, we analyzed well documented and geographically homogenous clinical isolates using a comparative genomics approach. Results A set of 254 H. pylori genes was used to perform array-based comparative genomic hybridization among 120 French H. pylori strains associated with chronic gastritis (n = 33, duodenal ulcers (n = 27, intestinal metaplasia (n = 17 or gastric extra-nodal marginal zone B-cell MALT lymphoma (n = 43. Hierarchical cluster analyses of the DNA hybridization values allowed us to identify a homogeneous subpopulation of strains that clustered exclusively with cagPAI minus MALT lymphoma isolates. The genome sequence of B38, a representative of this MALT lymphoma strain-cluster, was completed, fully annotated, and compared with the six previously released H. pylori genomes (i.e. J99, 26695, HPAG1, P12, G27 and Shi470. B38 has the smallest H. pylori genome described thus far (1,576,758 base pairs containing 1,528 CDSs; it contains the vacAs2m2 allele and lacks the genes encoding the major virulence factors (absence of cagPAI, babB, babC, sabB, and homB. Comparative genomics led to the identification of very few sequences that are unique to the B38 strain (9 intact CDSs and 7 pseudogenes. Pair-wise genomic synteny comparisons between B38 and the 6 H. pylori sequenced genomes revealed an almost complete co-linearity, never seen before between the genomes of strain Shi470 (a Peruvian isolate and B38. Conclusion These isolates are deprived of the main H. pylori virulence factors characterized previously, but are nonetheless associated with gastric neoplasia.

The results suggest that 0.05 g cm-2 is a reliable empirical lower bound for the clump surface densities required for massive-star formation to occur. The optically thick HCO+(1-0) and HNC(1-0) lines, as well as the optically thin N2H+(1-0) line were used to search for infall motions towards these sources. By analysing the asymmetries of the optically thick HCO+(1-0) and HNC(1-0) lines and the mapping observations of HCO+(1-0), a total of 131 reliable infall candidates have been identified. The HCO+(1-0) line shows the highest occurrence of obvious asymmetric features, suggesting that it may be a better infall motion tracer than other lines such as HNC(1-0). The detection rates of infall candidates towards pre-stellar, proto-stellar and UCHII clumps are 0.3452, 0.3861 and 0.2152, respectively. The relatively high detection rate of infall candidates towards UCHII clumps indicates that many UCHII regions are still accreting matter. The peak column densities and masses of the infall candidates, in general, display an increasing trend with progressing evolutionary stages. However, the rough estimates of the mass infall rate show no obvious variation with evolutionary stage.

    The aim of this study was to retrospectively analyze survival and tumor response data in patients with localized gastric MALT lymphoma treated by different treatment modalities other than anti-Helicobacter pylori treatment (diagnosis made before 1993, or after failure of antibiotics + anti-acid), including surgery, chemotherapy or combined treatment. Here we studied a series of 48 patients with stage IE or IIE disease treated during the past 11 years. These patients received different treatments: chemotherapy was proposed to 19 (40%) patients; gastric surgery to 21 (43%) patients, consisting of partial gastrectomy of 7 patients and total gastrectomy in 14 patients; combined treatment to 8 (17%) patients, consisting of surgery + chemotherapy in 7 patients and surgery + chemotherapy + radiotherapy in 1 patient. At diagnosis, 85% of the patients had good PS and no B symptoms. Complete response after treatment was reached in 45 (94%) patients (chemotherapy: 84% of the patients; surgery alone: 95%; combined treatment: 100%). Progression was observed in 16 (33%) patients. No statistical difference in the survival was found among the different therapeutic modalities: 5-year overall survival year FFP survival was 81% for chemotherapy, 86% for surgery alone and 95% for combined treatment. Prognostic factors for survival were age, performance status and hemoglobin level at diagnosis. Considering the natural bias of a retrospective analysis, surgery or chemotherapy was associated with a similar outcome in patients with MALT lymphoma after antibiotics failure. PMID:12688342

    Full Text Available A study was carried out over a two year period (2009/2010 and 2012/2013 on an experimental farm in the Alentejo region (Beja, in southern Portugal where rainfed malt barley (Hordeum distichum L. is sown at the end of autumn or beginning of winter (November- December. The aim of this experiment was to study the efficiency of the herbicide iodosulfuron-methyl-sodium to control post-emergence broadleaved weeds in this cereal crop. The malt barley crop was established using no-till farming. This technology provides the necessary machine bearing capacity of the soil to assure the post-emergence application of herbicides at two different weed development stages. The herbicide iodosulfuron-methyl-sodium was applied at three doses (5.0, 7.5, and 10.0 g a. i. · ha-1 and at two different broadleaved weed development stages (3 to 4 and 6 to 7 pairs of leaves, that also corresponded to two different crop development stages (beginning of tillering and complete tillering. The results indicated that early herbicide application timing provided a significantly higher efficiency for all the applied herbicide doses, but this better weed control was not reflected in a higher crop grain yield. The lack of a higher crop grain yield was probably due to a crop phytotoxicity of the herbicide, when used at an early application timing.

    A study was carried out on 43 malting barley samples collected in 2013 across the Umbria region (central Italy) to determine the incidence of the principal mycotoxigenic fungal genera, to identify the Fusarium species isolated from the grains, and to detect the presence of 34 fungal secondary metabolites by liquid chromatography-high-resolution mass spectrometry. The multimycotoxin-method development involved the evaluation of both a two-step solvent and QuEChERS protocol for metabolite extraction. The former protocol was selected because of better accuracy, which was evaluated on the basis of spike-recovery experiments. The most frequently isolated fungal species belonged to the genera Alternaria and Fusarium. The predominant Fusarium species was F. avenaceum, followed by F. graminearum. HT-2 toxin was the most frequently detected mycotoxin, followed by enniatin B, enniatin B1, T-2 toxin, and nivalenol. As a consequence of the observed mixed fungal infections, mycotoxin co-occurrence was also detected. A combination of mycological and mycotoxin analyses allowed the ability to obtain comprehensive information about the presence of mycotoxigenic fungi and their contaminants in malting barley cultivated in a specific geographic area.

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT is a well-characterized entity that may share clinical and morphological findings with other low-grade non-Hodgkin’s lymphomas. Dissemination of MALT-type lymphoma to bone marrow and peripheral blood simultaneously with the presence of T-large granular cell leukemia (T-LGL has rarely been reported. Case Presentation. This is the case of a 42-year-old male who presented with a gastric MALT-type lymphoma, disseminated to the bone marrow and the peripheral blood with high serum IgM levels and t(11;18(q21;q21. The morphological, immunophenotypical and, immunohistochemical studies of the successive bone marrow and peripheral blood samples had revealed the coexistence of two distinct lymphoma cell populations: a B-cell, marginal zone type population expressing CD19, CD20, CD22, CD79b, IgM, and kappa light chain, and a T-large granular cell population, developed after treatment with rituximab expressing CD3, CD8, CD5, CD7, and CD45. Conclusion. Based on the analysis of this unusual case we performed an extensive review of the literature to elucidate the relationship between T-LGL and B-cell lymphomas and to emphasize the importance of paraprotein analysis at diagnosis of gastric MALT lymphoma.

    Aiming at selecting high-quality malting barley varieties suitable to be planted in Hexi areas in Gansu Province and providing a basis for breeding new malting barley varieties in the future, the present study conducted adaptive planting for 26 malting barley vari-eties introduced from other provinces, and also measured a number of trait indicators. There existed some differences in agronomic and economic traits among different barley varieties. The plant height of the variety Baodan was only 48. 78 cm, so it could be used as a special germplasm materical to reduce plant height in barley breeding. The traits of early maturity present in 24 varieties might serve as a material resource for breading early mature barley that can avoid the harm of dry-hot wind. Some cultivars including Dafu 1, Bao-dan, and Ebarley 9 were superior in some traits to the control Ganpi 5. Based on the data of these agronomic and economic traits, a clustering analysis was performed, which divided 27 barley cultivars into two categories, reflecting a certain degree of genetic differ-ences among these introduced cultivars.%为了筛选适合甘肃河西地区种植的早熟优质啤酒大麦,同时给后期啤酒大麦品种选育提供依据,对引自其他省份的26个早熟啤酒大麦品种进行适应性种植,并测定了多项性状指标。结果表明,引进大麦品种在农艺性状、经济性状上存在一定的差异。宝丹的株高仅48.78 cm,是降低大麦株高的特殊种质资源;24个品种的早熟特性为培育可以躲避干热风危害的早熟大麦提供了物质基础。大福1号、宝丹、鄂大麦9号等一些品种在部分性状上要优于对照甘啤5号。利用性状数据进行聚类分析,将27个大麦品种明显分成两大类,从一定程度上反映出不同品种间的遗传差异。

Se llevaron a cabo ocho experimentos a campo en diferentes sitios de la provincia de Buenos Aires, en los años 1999 y 2000, para determinar el efecto del nitrógeno sobre el crecimiento, la absorción de N del suelo y del fertilizante, el rendimiento y la concentración de N en grano. Los tratamientos fueron 0, 30 y 60 kg N ha-1 aplicados a la emergencia de la planta, 30 y 60 kg N ha-1 aplicados en macollaje temprano, y 60 kg N ha-1 fraccionado en dos momentos: 30 kg N ha-1 cada uno aplicados a la emergencia y en macollaje temprano. Dentro de cada parcela se ubicó una microparcela a la que se le aplicó urea marcada con 15N. En cuatro momentos del ciclo de la cebada, desde macollaje temprano hasta madurez fisiológica, se evaluó la producción de materia seca y la absorción de N de plantas extraídas de las microparcelas. El crecimiento continuó hasta madurez fisiológica, y generalmente alcanzó el máximo después de antesis, en coincidencia con el período de mayor absorción de nitrógeno. La dosis de 30 kg N ha-1 aumentó el rendimiento pero no la concentración de N del grano. El agregado de 60 kg N ha-1 afectó ambos. El momento de aplicación de N no afectó el rendimiento de la materia seca ni la concentración de N en el grano. La variación en la absorción de N entre sitios fue mayor que la variación en la absorción de N del fertilizante. El Índice de Cosecha de Nitrógeno no fue afectado por las dosis de N aplicado.There is a lack of data associated with applications of nitrogen fertilizer to increase yield while not increasing seed protein to levels exceeding those acceptable for malting barley in Buenos Aires province.

Methods: patients with gastric MALT lymphoma diagnosed in our hospital during the last 15 years were retrospectively included. Demographic, clinic, analytic, endoscopic, and histological variables were reviewed. The extension study, the staging classification, and the presence of H. pylori infection were assessed. Results: thirty-seven patients with gastric MALT lymphoma were identified. Mean age was 61 years, with 62% of males. The most common presentation symptom was dyspepsia (76%, followed by digestive bleeding (11% and constitutional syndrome (8%. At endoscopy, erosive lesions were identified in 41%, and proliferative or exophytic lesions in 43%. Most lymphomas were classified as low-grade (68%. The stage distribution was EI for 56%, EII for 13%, EIII for 3%, and EIV for 28%. The prevalence of H. pylori infection (histology in all cases, rapid urease test in 19%, and 13C-urea breath test in 24% was 46%. When only low-grade lymphomas in stage EI were considered, H. pylori prevalence increased to 55%. When H. pylori infection was evaluated by 13C-urea breath testing (in addition to histology, the prevalence of H. pylori infection increased to 78%. Conclusions: it is probable that the reduced H. pylori prevalence found in some studies, as in ours, could be explained by false-negative results obtained when only one diagnostic method was used. Therefore, at least two (invasive diagnostic methods should be performed. Furthermore, the performance of a non-invasive diagnostic method (such as a 13C-urea breath test before the exclusion of H. pylori infection should be considered.Objetivo: revisar retrospectivamente las características clínicas y la prevalencia de infección por H. pylori en los pacientes con linfoma MALT gástrico diagnosticados

    The demand for gluten-free foods is certainly increasing. Interest in teff has increased noticeably due to its very attractive nutritional profile and gluten-free nature of the grain, making it a suitable substitute for wheat and other cereals in their food applications as well as foods for people with celiac disease. The main objective of this article is to review researches on teff, evaluate its suitability for different food applications, and give direction for further research on its applications for health food market. Teff is a tropical low risk cereal that grows in a wider ecology and can tolerate harsh environmental conditions where most other cereals are less viable. It has an excellent balance of amino acid composition (including all 8 essential amino acids for humans) making it an excellent material for malting and brewing. Because of its small size, teff is made into whole-grain flour (bran and germ included), resulting in a very high fiber content and high nutrient content in general. Teff is useful to improve the haemoglobin level in human body and helps to prevent malaria, incidence of anaemia and diabetes. The nutrient composition of teff grain indicates that it has a good potential to be used in foods and beverages worldwide. The high levels of simple sugars and α-amino acids as a result of breakdown of starch and protein, respectively, are essential for fermentation and beer making. PMID:26396284

    A single step extraction-cleanup procedure using porous membrane-protected micro-solid phase extraction (μ-SPE) in conjunction with liquid chromatography-tandem mass spectrometry for the extraction and determination of aflatoxins (AFs) B1, B2, G1 and G2 from food was successfully developed. After the extraction, AFs were desorbed from the μ-SPE device by ultrasonication using acetonitrile. The optimum extraction conditions were: sorbent material, C8; sorbent mass, 20mg; extraction time, 90 min; stirring speed, 1,000 rpm; sample volume, 10 mL; desorption solvent, acetonitrile; solvent volume, 350 μL and ultrasonication period, 25 min without salt addition. Under the optimum conditions, enrichment factor of 11, 9, 9 and 10 for AFG2, AFG1, AFB2 and AFB1, respectively were achieved. Good linearity and correlation coefficient was obtained over the concentration range of 0.4-50 ng g(-1) (r(2) 0.9988-0.9999). Good recoveries for AFs ranging from 86.0-109% were obtained. The method was applied to 40 samples involving malt beverage (19) and canned coffee (21). No AFs were detected in the selected samples. PMID:24206720

  7. C-type lectin receptor dectin-3 mediates trehalose 6,6'-dimycolate (TDM)-induced Mincle expression through CARD9/Bcl10/MALT1-dependent nuclear factor (NF)-κB activation.

    Previous studies indicate that both Dectin-3 (also called MCL or Clec4d) and Mincle (also called Clec4e), two C-type lectin receptors, can recognize trehalose 6,6'-dimycolate (TDM), a cell wall component from mycobacteria, and induce potent innate immune responses. Interestingly, stimulation of Dectin-3 by TDM can also induce Mincle expression, which may enhance the host innate immune system to sense Mycobacterium infection. However, the mechanism by which Dectin-3 induces Mincle expression is not fully defined. Here, we show that TDM-induced Mincle expression is dependent on Dectin-3-mediated NF-κB, but not nuclear factor of activated T-cells (NFAT), activation, and Dectin-3 induces NF-κB activation through the CARD9-BCL10-MALT1 complex. We found that bone marrow-derived macrophages from Dectin-3-deficient mice were severely defective in the induction of Mincle expression in response to TDM stimulation. This defect is correlated with the failure of TDM-induced NF-κB activation in Dectin-3-deficient bone marrow-derived macrophages. Consistently, inhibition of NF-κB, but not NFAT, impaired TDM-induced Mincle expression, whereas NF-κB, but not NFAT, binds to the Mincle promoter. Dectin-3-mediated NF-κB activation is dependent on the CARD9-Bcl10-MALT1 complex. Finally, mice deficient for Dectin-3 or CARD9 produced much less proinflammatory cytokines and keyhole limpet hemocyanin (KLH)-specific antibodies after immunization with an adjuvant containing TDM. Overall, this study provides the mechanism by which Dectin-3 induces Mincle expression in response to Mycobacterium infection, which will have significant impact to improve adjuvant and design vaccine for antimicrobial infection.

    OBJECTIVE: To understand the molecular mechanism of BCL10 over-expression on malignant phenotype of MALT lymphoma by using EμSR-BCLlO transgenic mice model. METHOD: Precursor of MALT lymphoma-marginal B cells were found highly expanded in EμSR-BCL10 transgenic mice. Signature markers for these cells were IgM+ / CD21hugh/CD23low, and MZ B cells in transgenic mice were evaluated by staining of these three anti-bodies followed by flow cytometry analysis. Those cells were also isolated by CD43 microbeads followed by CD23 microbeads double negative selection, and proliferation assays were performed on these separated cells. In vivo anti-apoptotic effect to MZ B cells of o-ver-expressed BCL10 were evaluated by injection of anti-IgM through tail vein. RESULTS: MZ B cell expanded in transgenic mice in a dose-dependent manner with BCL10 protein manner. Proliferation of MZ B cells from transgenic mice showed 2 - 5 times higher than those from FVB mice at the stimulation of anti-IgM, but no significant differences were observed on LPS and PMA + Ionomycin stimulation. Anti-IgM could induce apoptosis to MZ B cells of FVB mice but not transgenic mice in vivo. CONCLUSIONS: Over-expression of BCL10 causes MZ B cell expansion in a dose-dependent manner, which exerts proliferation-promoting and anti-apoptotic effects through BCR receptor pathway of marginal zone B cells. Our results may explain high-grade MLAT lymphoma malignant phenotypes.%目的:运用EμSR-BCL10转基因小鼠模型研究BCL10高表达致黏膜相关淋巴组织(MALT)淋巴瘤的分子机制.方法:用IgM+/CD21 lugh/CD23 low荧光标记的抗体染色后进行流式细胞仪分析MZ B细胞;用CD43和CD23磁珠抗体双阴性分离方法获得MZ B细胞并用于体外增殖刺激实验;使用anti-IgM体内注射法研究BCL10体内抗凋亡.结果:MZB细胞增生与BCL10蛋白表达水平存在量效关系.细胞增殖实验结果显示,anti-IgM刺激时转基因小鼠的MZB细胞比FVB野生型

Realizando simulaciones con 27 acciones y el Índice de Precios y Cotizaciones de la Bolsa Mexicana de Valores se verifica la hipótesis principal y se comprueba que, efectivamente, en muchos casos, el uso del proceso de frenado con el oscilador %R de Williams permite tomar mejores decisiones. Por otro lado, se concluye que de los dos disparadores de señales el que mejor funciona, tanto para %K como para %R es el uso de cotas inferior y superior. Este artículo surgió en el curso de una investigación sobre el análisis técnico bursátil de acciones que se puede realizar en su totalidad por computadora y que, esencialmente, excluye el análisis gráfico. Uno de los propósitos del estudio es determinar si es posible, y bajo qué mecanismos, establecer un sistema de análisis bursátil que le permita al inversionista tomar decisiones de inversión en acciones en la Bolsa Mexicana de Valores sin tener que emplear la considerable cantidad de tiempo que es necesario para el análisis gráfico tradicional. Durante este estudio se realizó un análisis preliminar de unos 120 indicadores técnicos para, por un lado, conocerlos con cierto detalle y, por otra parte, aislar aquellos que prometían ser de utilidad para el objetivo de la investigación. Fue en este proceso cuando se detectó que existen dos indicadores que están relacionados y que permiten un análisis por separado que tiene, cuando menos, dos ventajas.

  12. Para-equilibrium phase diagrams

    International Nuclear Information System (INIS)

    Highlights: • A rapidly cooled system may attain a state of para-equilibrium. • In this state rapidly diffusing elements reach equilibrium but others are immobile. • Application of the Phase Rule to para-equilibrium phase diagrams is discussed. • A general algorithm to calculate para-equilibrium phase diagrams is described. - Abstract: If an initially homogeneous system at high temperature is rapidly cooled, a temporary para-equilibrium state may result in which rapidly diffusing elements have reached equilibrium but more slowly diffusing elements have remained essentially immobile. The best known example occurs when homogeneous austenite is quenched. A para-equilibrium phase assemblage may be calculated thermodynamically by Gibbs free energy minimization under the constraint that the ratios of the slowly diffusing elements are the same in all phases. Several examples of calculated para-equilibrium phase diagram sections are presented and the application of the Phase Rule is discussed. Although the rules governing the geometry of these diagrams may appear at first to be somewhat different from those for full equilibrium phase diagrams, it is shown that in fact they obey exactly the same rules with the following provision. Since the molar ratios of non-diffusing elements are the same in all phases at para-equilibrium, these ratios act, as far as the geometry of the diagram is concerned, like “potential” variables (such as T, pressure or chemical potentials) rather than like “normal” composition variables which need not be the same in all phases. A general algorithm to calculate para-equilibrium phase diagrams is presented. In the limit, if a para-equilibrium calculation is performed under the constraint that no elements diffuse, then the resultant phase diagram shows the single phase with the minimum Gibbs free energy at any point on the diagram; such calculations are of interest in physical vapor deposition when deposition is so rapid that phase

    RVA(Rapid visco-analyzer) can be used to detect the visco of malting barley to predict the sprout damage of malting barley according to the characteristic.However,there are no uniform EBC or ASBC standards of this method up to now.Moisture,varieties specificity,smash size and so on can affect the results of this method.In the study we created a method of RVA,and analyze the effects of these factors to RVA,The results showed that the initial mass and smash size of barley are two significant factor to the RVA value of barley,while the effects of moisture is less important.The level of sprout damage of malting barley had a remarkable correlation with RVA.We can use this fast,sensitive and convenient method to predict the sprout damages of malting barley.%使用快速黏度分析仪(rapid visco-analyzer,RVA)测定大麦的黏度并通过其特征值可以预测大麦预发芽程度,目前尚无统一的EBC、ASBC标准方法。大麦水分、品种特异性、粉碎粒度等因素在一定程度上影响此方法检测结果。文中建立了一种RVA检测方法,并分析了不同因素对其特征值的影响。实验结果显示,品种初始质量、粉碎粒度对大麦RVA值影响较大,水分影响较小。RVA对大麦预发芽程度的预测相关性显著,可作为一种快速、灵敏、简便的方法,预测大麦预发芽损伤。

    Full Text Available Introducción: La anestesia espinal o subaracnoidea brinda al paciente calidad y múltiples ventajas. Sin embargo, en procedimientos quirúrgicos que comprometen al abdomen superior ha sido poco empleada, como en la colecistectomía. En estas cirugías, ya sean laparoscópicas o abiertas, se ha empleado de forma rutinaria la anestesia general. Objetivo: Describir la aplicación de anestesia espinal para la realización de colecistectomía abierta. Materiales y métodos: Es un estudio retrospectivo, serie de casos, que evaluó 32 pacientes ASA I y II a los que se les realizó colecistectomía abierta, bajo anestesia espinal, en el tiempo comprendido entre junio de 2002 y junio de 2004, en un Hospital Nivel II de la ciudad de Popayán, previo consentimiento aprobado por el Comité Científico del Hospital. Resultados: En 25 mujeres y 7 hombres, con edad media de 33,6 años, se observó que la frecuencia cardiaca y la presión arterial sistólica, diastólica y media disminuyeron durante los primeros 20 minutos; luego, sus valores se incrementaron hasta estabilizarse por debajo de los parámetros iniciales respectivos. El 34,3% de la población presentó eventos transoperatorios como hipotensión, bradicardia, náusea, vómito, dolor en hombro o dolor torácico. En dos de estos Caucapacientes fue necesario cambiar a anestesia general. En el postoperatorio, 21,7% de los pacientes presentaron efectos adversos: náusea, vómito y cefalea. El 90 % egresaron del hospital en las primeras 48 horas. No se reportó mortalidad intra o postoperatorio inmediata. Conclusiones: La anestesia espinal es una alternativa a tener en cuenta para procedimientos como la colecistectomía abierta.Introduction: Spinal anaesthesia offers patients quality as well as several advantages; however in surgical procedures which involve the upper abdomen it had been less employed in procedures such as cholecistectomy by laparoscopic technique or via opening the abdomen where the

    Full Text Available Las instituciones educativas constituyen los principales factores en la construcción social de un nuevo sistema educativo. Las escuelas y los educadores controlan y producen propiedad intelectual de una extraordinaria profundidad y amplitud. Los cambios producidos por las tecnologías digitales están consiguiendo que el acceso y la producción de conocimiento sea más accesible y universal. Lo que es, a la vez, un gran logro de apertura curricular, pero también un grave peligro de perder la perspectiva eminentemente “educativa” de la transmisión del conocimiento en la escuela. Los nuevos recursos permiten a los educadores romper el ciclo de reproducción en los logros educativos, acercarse al medio y a la familia y transformar la escuela. Los educadores y las escuelas deben asumir el reto de constituir comunidades de aprendizaje. Así como de atreverse a producir y difundir ese conocimiento con soporte digital. Lo contrario sería una terrible abdicación. El artículo traza un recorrido histórico sobre esta función de la escuela y su adaptación a los medios y recursos de cada época. Tras lo cual, aboga por asumir el desafío actual de las TICs, para renovar el vínculo progresista con la posteridad y construir un mejor futuro. Los nuevos recursos permiten a los educadores romper el ciclo de reproducción en los logros educativos, acercarse al medio y a la familia y transformar la escuela.

  19. Planar Para Algebras, Reflection Positivity

    CERN Document Server

    Jaffe, Arthur

    2016-01-01

    We define the notion of a planar para algebra, which arises naturally from combining planar algebras with the idea of $\\Z_{N}$ para symmetry in physics. A subfactor planar para algebra is a Hilbert space representation of planar tangles with parafermionic defects, that are invariant under isotopy. For each $\\Z_{N}$, we construct a family of subfactor planar para algebras which play the role of Temperley-Lieb-Jones planar algebras. The first example in this family is the parafermion planar para algebra. Based on this example, we introduce parafermion Pauli matrices, quaternion relations, and braided relations for parafermion algebras which one can use in the study of quantum information. Two different reflections play an important role in the theory of planar para algebras. One is the adjoint operator; the other is the modular conjugation in Tomita-Takesaki theory. We use the latter one to define the double algebra and to introduce reflection positivity. We give a new and geometric proof of reflection positivi...

    Somatostatin receptor (SSTR) scintigraphy and gallium-67 citrate ({sup 67}Ga) scintigraphy have been used for visualisation of Hodgkin's lymphoma and non-Hodgkin's lymphoma. However, experience with B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) type is very limited. The aim of this study was to prospectively compare the {sup 67}Ga scintigraphy results with those obtained by {sup 111}In-DOTA-dPhe{sup 1}-Tyr{sup 3}-octreotide ({sup 111}In-DOTA-TOCT) and {sup 111}In-DOTA-lanreotide ({sup 111}In-DOTA-LAN) scintigraphy in patients with proven MALT-type lymphoma. Comparative scintigraphic examinations using {sup 67}Ga, {sup 111}In-DOTA-TOCT and {sup 111}In-DOTA-LAN were performed in 18 patients (11 female and 7 male, median age 64{+-}15 years) with histologically verified MALT-type lymphomas of various origin.

    Full Text Available Sensibilidade ao glúten é um estado de elevada resposta iamunológica (celular e humoral à ingestão de proteínas do glúten do trigo, centeio, cevada e aveia, em indivíduos geneticamente predispostos. A doença celíaca é sua expressão mais freqüente, variando as formas de apresentação. Tem como tratamento a exclusão de alimentos contendo as gliadinas tóxicas. Embora a biopsia do intestino delgado proximal seja necessária, tem-se ressaltado a importância de testes sorológicos no rastreamento, diagnóstico e monitorização da dieta isenta de glúten em pacientes com doença celíaca. O objetivo do presente estudo foi investigar a presença dos anticorpos antiendomísio (EmA-IgA e anti-reticulina (ARA-IgA em 56 pacientes celíacos (17 recém diagnosticados; 24 aderentes à dieta; 15 com transgressão à dieta. Os anticorpos foram detectados por imunofluorescência indireta, utilizando como substrato cordão umbilical humano para os EmA-IgA, fígado e rim de rato para os ARA-IgA. Nos pacientes recém diagnosticados e no grupo com transgressão à dieta houve positividade total de 100% para os EmA-IgA e 59,4% para ARA-IgA. Nos pacientes aderentes à dieta nenhum dos anticorpos foi detectado. Dentre os 32 pacientes positivos, a concordância foi de 59,4% (19, sendo que 40,6 % (13/32 eram ARA-IgA negativo e EmA-IgA positivo. Nenhum paciente mostrou-se positivo para os ARA-IgA e negativo para os EmA-IgA. Portanto, a sensibilidade para os EmA-IgA foi de 100% e de 59,4% para os ARA-IgA. A associação dos dois testes não aumentou os índices de positividade total nas amostras. Conclui-se que, atualmente, a pesquisa dos EmA-IgA pode constituir teste sorológico de escolha, seja para diagnóstico, seja para seguimento dos pacientes celíacos, pelo alto valor preditivo, alta sensibilidade e especificidade e relativo baixo custo quando se utiliza cordão umbilical humano como substrato.Sensibility to gluten is a condition with high

  17. Separating Para and Ortho Water

    CERN Document Server

    Horke, Daniel A; Długołęcki, Karol; Küpper, Jochen

    2014-01-01

    Water exists as two nuclear-spin isomers, para and ortho, determined by the overall spin of its two hydrogen nuclei. For isolated water molecules the conversion between these isomers is forbidden and they act as different molecular species. Yet, these species are not readily separable, and little is known about their specific physical and chemical properties, conversion mechanisms, or interactions. Here we demonstrate the production of isolated samples of both spin isomers in pure beams of para and ortho water, with both species in their respective absolute ground state. These single-quantum-state samples are ideal targets for unraveling spin-conversion mechanisms, for precision spectroscopy and fundamental-symmetry-breaking studies, and for spin-enhanced applications, e. g., laboratory astrophysics and -chemistry or hypersensitized NMR experiments.

    Full Text Available Descrevem-se dois surtos de uma doença neurológica que afetou rebanhos bovinos leiteiros que consumiam bagaço de malte contaminado por Aspergillus clavatus no município de Viamão, estado do Rio Grande do Sul. A morbidade em ambos os surtos foi em torno de 30% e a letalidade, 50% e 100%. A evolução clínica da doença variou de 5 a 64 dias. Dentre os animais que se recuperaram apenas um permaneceu com seqüelas locomotoras leves. Os sinais clínicos eram predominantemente locomotores e incluíam tremores musculares de intensidade variável, hiperestesia e membros pélvicos com ataxia, paresia e paralisia progessivas, e apoio sobre os boletos. Os distúrbios locomotores eram intensificados pelo exercício que, em geral, desencadeava quedas. Havia também marcada queda na produção leiteira, no entanto o apetite e a dipsia eram mantidos até próximo da morte ou eutanásia. Cinco bovinos foram necropsiados e destes dois apresentaram lesões macroscópicas nos músculos esqueléticos, principalmente nos membros pélvicos e torácicos caracterizadas por alterações necróticas e mineralização. No sistema nervoso, os principais achados consistiam de degeneração e necrose neuronal cromatolítica em núcleos nervosos específicos no tronco encefálico, nos cornos ventrais da medula espinhal e nos gânglios trigeminal, estrelado, celíaco e espinhais. Em dois bovinos havia adicionalmente degeneração walleriana nos funículos dorsais da medula espinhal e nervos isquiádico e fibular. O diagnóstico foi baseado nos dados epidemiológicos, sinais clínicos, achados de necropsia, histopatológicos e micológicos.

Surgieron tres temas: la salud y la enfermedad - valores culturales del cuidado de si; las prácticas del cuidado de la salud y cuidándose en el embarazo garantiza tener un hijo más saludable. Los temas culturales revelaron que las creencias, los valores, los hábitos y los patrones culturales comportamentales, conforme las tres maneras de acción identificadas, pueden ser preservadas, acomodadas y re-estructuradas para proporcionar un cuidado culturalmente congruente.

  1. (Para-)Hermitian and (para-)K\\"ahler Submanifolds of a para-quaternionic K\\"ahler manifold

    2012-01-01

    On a para-quaternionic K\\"ahler manifold $(\\widetilde M^{4n},Q,\\widetilde g)$, which is first of all a pseudo-Riemannian manifold, a natural definition of (almost) K\\"ahler and (almost) para-K\\"ahler submanifold $(M^{2m},\\mathcal{J},g)$ can be given where $\\mathcal{J}=J_1|_M$ is a (para-)complex structure on $M$ which is the restriction of a section $J_1$ of the para-quaternionic bundle $Q$. In this paper, we extend to such a submanifold $M$ most of the results proved by Alekseevsky and Marchiafava, 2001, where Hermitian and K\\"ahler submanifolds of a quaternionic K\\"ahler manifold have been studied. Conditions for the integrability of an almost (para-)Hermitian structure on $M$ are given. Assuming that the scalar curvature of $\\widetilde M$ is non zero, we show that any almost (para-)K\\"ahler submanifold is (para-)K\\"ahler and moreover that $M$ is (para-)K\\"ahler iff it is totally (para-)complex. Considering totally (para-)complex submanifolds of maximal dimension $2n$, we identify the second fundamental for...

    Full Text Available Le Comité d'Etudes Pétrolières Marines (CEPM et le Centre National pour l'Exploitation des Océans (CNEXO ont mené une série d'études sous-marines des escarpements ioniens pour en définir l'origine, l'âge et l'évolution. Les résultats présentés ici concernent l'escarpement de Malte, le mont Alfeo et les monts de Médine à l'ouest et au sud-ouest du bassin Ionien profond. Ils comprennent les données bathymétriques sous forme d'une carte à 1/100 000 hors texte, l'analyse morphologique des reliefs, les déterminations stratigraphiques effectuées sur les échantillons récoltés en dragages, carottages ou en plongées, l'analyse structurale à partir de profils de sismique réflexion et des plongées, et l'étude de la subsidence depuis le Trias supérieur à partir des forages réels du plateau maltais et des forages fictifs du rebord de l'escarpement de Malte. Les conclusions font ressortir : - l'existence de séries carbonatées de plate-forme d'âge Jurassique inférieur pour l'escarpement de Malte et le mont Alfeo, et Crétacé inférieur pour les monts de Médine; - un changement paléogéographique majeur : à partir du Jurassique supérieur pour l'escarpement de Malte et à partir de l'Albien pour ceux de Médine; - l'existence de séries condensées à dater de ce changement paléogéographique et d'une érosion constante jusqu'à l'Actuel, érosion dont les processus variés ont de nombreuses conséquences sur la sédimentation de tels reliefs; - quatre phases de subsidence essentielles : Jurassique moyen, limite Crétacé inférieur-Crétacé supérieur, Miocène inférieur et moyen, Plio-Quaternaire. La parenté du mont Alfeo avec l'escarpement de Malte a été bien reconnue, par contre, les monts de Médine ne semblent se rattacher à leur histoire qu'à partir du Crétacé supérieur et ont sans doute une évolution comparable au plateau cyrénien.

Este trabajo tiene por objetivo estudiar las diversas aplicaciones existentes en las redes sociales y evaluar su posible utilización en el diseño de una red social para bibliotecas universitarias. Como resultado pretende construir un modelo de prototipo completo para ser implantado en una biblioteca. El trabajo consta de tres partes. La primera de ellas es una introducción a las redes sociales que menciona aspectos como idea, historia y desarrollo, contenidos y elementos y analiza distintos ejemplos de redes sociales. La siguiente parte es un análisis de presencia de bibliotecas en las redes sociales. Se habla de la posibilidad de crear redes sociales para las bibliotecas, ventajas y desventajas para éstas, presentando ejemplos de bibliotecas que participan en redes o intentan crear sus propias redes. También se analiza aplicaciones que usan las bibliotecas presentes en redes sociales. A continuación se propone el proyecto de red social para una biblioteca universitaria.

    Full Text Available OBJETIVO: Estudar as variáveis contempladas na Declaração de Nascimento (DN como possíveis fatores de risco para nascimentos pequenos para a idade gestacional (PIG e o retardo de crescimento intra-uterino como fator de risco para a mortalidade neonatal. MATERIAL E MÉTODO: As variáveis existentes na DN foram obtidas diretamente de prontuários hospitalares. Os dados referem-se a uma coorte de nascimentos obtida por meio da vinculação das declarações de nascimento e óbito, correspondendo a 2.251 nascimentos vivos hospitalares, de mães residentes, ocorridos no Município de Santo André, Região Metropolitana de São Paulo, no período de l/1 a 30/6/1992, e aos óbitos neonatais verificados nessa coorte. RESULTADOS: Obteve-se a proporção de 4,3% de nascimentos PIG, significativamente maior entre os recém-nascidos de pré-termo e pós-termo, entre os nascimentos cujas mães tinham mais de 35 anos de idade e grau de instrução inferior ao primeiro grau completo. Os recém-nascidos PIG apresentam maior risco de morte neonatal que aqueles que não apresentavam sinais de retardo de crescimento intra-uterino. CONCLUSÕES: Em áreas com menor freqüência de baixo peso ao nascer, é importante investigar a presença de retardo de crescimento intra-uterino entre os nascimentos prematuros e não apenas nos nascimentos de termo. O registro da data da última menstruação (ou da idade gestacional em semanas não agregadas na DN facilitaria a detecção de PIGs na população de recém-nascidos.

Este está inserido na linha de pesquisa: educação, trabalho e emancipação do mestrado em educação desta Universidade. Queremos compreender, à luz do materialismo histórico e dialético e das categorias da crítica da economia política, os significados atribuídos pelos estudantes universitários ao fenômeno trabalho e estudo. É uma pesquisa preferentemente qualitativa de natureza dialética. Para Marx, a essência da realidade humana reside no trabalho, mas a fonte de toda a riqueza está na natureza. Logo trabalho, natureza e sociedade estão em relação dialética. Trabalho, portanto, é a ideia central articuladora, e natureza e sociedade devem ser estudadas em conexão com o trabalho. Marx trata o trabalho, no modo de produção capitalista, como um impedimento ao desenvolvimento humano. Propõe omesmo como um ato de criação e auto-expressão humana que não deve ter um valor. A compreensão dessa premissa é necessária para que os trabalhadores possam significar e ressignificar o trabalho para além da ideologia dominante. Algumas categorias aparecem como relevantes para a análise: condições de trabalho e de estudo, necessidade de formação, predominância do trabalho sobre o estudo, dificuldade deconciliar tempo de estudo e de trabalho. Na relação com o objeto de estudo, ressaltaremos a crise estrutural do capital, a desregulamentação das leis do trabalho e sua flexibilização e as contradições entre trabalho e estudo bem como quais possibilidades emancipatórias são visualizadas ou sonhadas pelos trabalhadores estudantes.Resume Ce travail constitue une partie de la recherche entreprise avec les étudiants du cours de pédagogie de l´Universidade de Santa Cruz do Sul – UNISC – RS – Brésil.

Somos conscientes de que, para conseguir este tipo de aprendizaje, es necesario introducir una serie de cambios en la dinámica de la clase. Comenzamos diferenciando el aprendizaje maquinal del significativo. Continuamos aclarando una confusión muy extendida entre muchos educadores, que creen que el aprendizaje por recepción es repetitivo y que el efectuado por descubrimiento es forzosamente significativo. Posteriormente, planteamos una serie de interrogantes para aclarar algunas cuestiones que le pueden ser útiles a los educadores en su práctica cotidiana. Terminamos presentando la estrategia de organización, que cuenta con dos instrumentos, a nuestro juicio muy eficaces, para ayudar a los estudiantes, a aprender de manera significativa: los mapas conceptuales y la técnica heurística V.ABSTRACT: We start from the assumption that one of the questions that most worry the teaching staff in its educational practice consists in that its pupils' learning is significant. We are aware that, to obtain this kind of learning, it is necessary to introduce a series of changes in the classroom dynamics. We begin by making a distinction between mechanical and significant learning. We continué making clear a very extended confusión amongst many teachers, who believe that learning by reception is repetitive and that the one done by serendipity is necessarily significant. Afterwards, we créate a series of questions to clarify with some answers that can be useful to teachers in their everyday practice. We finish showing the organization strategy, which has two instruments, that in our opinión are very effective, to help students learning in a significant way: conceptual maps and the V heuristic technique.RÉSUMÉ: Nous partons de la supposition de qu'une des questions que

    2014-01-01

    Let Mn be an n-dimensional submanifold without umbilical points in the (n+1)-dimen-sional unit sphere Sn+1. Four basic invariants of Mn under the Moebius transformation group of Sn+1 are a1-form Φ called moebius form, a symmetric (0, 2) tensor A called Blaschke tensor, a symmetric (0, 2) tensor B called Moebius second fundamental form and a positive definite (0, 2) tensor g called Moebius metric. A symmetric (0, 2) tensor D = A+μB called para-Blaschke tensor, where μ is constant, is also an Moebius invariant. We call the para-Blaschke tensor is isotropic if there exists a function λ such that D = λg. One of the basic questions in Moebius geometry is to classify the hypersurfaces with isotropic para-Blaschke tensor. When λ is not constant, all hypersurfaces with isotropic para-Blaschke tensor are explicitly expressed in this paper.

Para ampliar los reportes oficiales de la comercialización de alimentos para perros se creó una base de datos que incluyó cantidad, costo, empaque y formulación durante el período 1998 a agosto del 2000. De 1995 a 1998 y de 1996 a 1999 la producción nacional incrementó un 90,4% y la importación un 42,56% respectivamente, ocupando los alimentos nacionales un 72% del tonelaje y un 70% del valor en dólares americanos. No fue posible determinar cuál es el empaque más comercializado, pero si que los alimentos extrusados son los que ocupan el primer lugar y que los alimentos recomendados para cachorros y adultos son los que más se comercializan. La ausencia de datos en las declaraciones sugiere la necesidad de incrementar el control en las mismas en caso de requerirse un estudio de mercado, ya que contrariamente a esta situación el mayor número de garantías inscritas corresponden separadamente para las fases de cachorros y adultos. Merece también atención que las garantías indican mayores porcentajes de proteína cruda que los recomendados por la AAFCO y que al menos 36 fórmulas son recomendadas para estados sanitarios específicos (p.e. para perros con problemas de alergias, cálculos renales, pérdidas de pelo, etc. sin que oficialmente se encuentre registrada ninguna fórmula medicada

    The ParaScope parallel programming environment, developed to support scientific programming of shared-memory multiprocessors, includes a collection of tools that use global program analysis to help users develop and debug parallel programs. This paper focuses on ParaScope's compilation system, its parallel program editor, and its parallel debugging system. The compilation system extends the traditional single-procedure compiler by providing a mechanism for managing the compilation of complete programs. Thus, ParaScope can support both traditional single-procedure optimization and optimization across procedure boundaries. The ParaScope editor brings both compiler analysis and user expertise to bear on program parallelization. It assists the knowledgeable user by displaying and managing analysis and by providing a variety of interactive program transformations that are effective in exposing parallelism. The debugging system detects and reports timing-dependent errors, called data races, in execution of parallel programs. The system combines static analysis, program instrumentation, and run-time reporting to provide a mechanical system for isolating errors in parallel program executions. Finally, we describe a new project to extend ParaScope to support programming in FORTRAN D, a machine-independent parallel programming language intended for use with both distributed-memory and shared-memory parallel computers.

Si no se encuentran medidas para incrementar la competitividad regional de este sub-sector, los países centroamericanos experimentarán impactos negativos en las áreas sociales y económicas de considerable magnitud, especialmente ahora que Centro América necesita ajustar su economía a los nuevos requerimientos de mercados mas abiertos, como el Tratado Centroamericano de Libre Comercio con USA (TLC. Vendedores de frijoles a nivel intermediario y de consumo final, así como técnicos de oficinas gubernamentales dedicadas al mercadeo de frijoles en Centro América fueron entrevistados para documentar los cambios experimentados, identificar los obstáculos que frenan la viabilidad del sub-sector e identificar las oportunidades de incremento de mercados en el futuro para los productores y vendedores de frijol. Los resultados muestran que para que continúen siendo competitivos, los países centroamericanos deben incrementar la productividad a través del apoyo a las investigaciones para el mejoramiento de variedades de frijol, especialmente aquellas que los consumidores prefieren por características específicas (e.g. color. También es imprescindible el fortalecimiento de los programas de distribución de variedades mejoradas a los productores; las mejoras en la transmisión de información de mercado a los productores; el fortalecimiento de los contactos entre productores, comercializadores a nivel mayorista y supermercados; y una política más específica de apertura de mercados de exportación, especialmente con los Estados Unidos.

  11. Imaging of limbic para-neoplastic encephalitis

    International Nuclear Information System (INIS)

    Para-neoplastic limbic encephalitis is a rare syndrome mostly associated with small cell lung cancer. We present the case of a 69-year-old man with selective amnesia suggesting limbic encephalitis. A neuroendocrine cell lung cancer was found, confirming the diagnostics of para-neoplastic limbic encephalitis. Contrast-enhanced cerebral CT was normal whether magnetic resonance imaging showed signal abnormalities of the medial part of temporal lobes and hippocampal regions. Because neurologic improvement may follow treatment of the primary tumor, early diagnosis is important. (authors)

    Full Text Available INTRODUÇÃO: Os valores de referência de indicadores biológicos são utilizados como parâmetros para interpretação de resultados de valores obtidos em indivíduos expostos ocupacionalmente aos agentes químicos. O Grupo Brasileiro para Estabelecimento dos Valores de Referência tem se dedicado a estas determinações objetivando estabelecer valores de referência para os diferentes bioindicadores em diversas regiões do País. Determinaram-se os valores de referência para a carboxiemoglobina (COHb no Sul de Minas Gerais. MATERIAL E MÉTODO: A COHb foi analisada pelo método espectrofométrico, otimizado no laboratório de análises toxicológicas. Em todas as amostras também foram realizadas análises de alguns parâmetros bioquímicos e hematológicos para atestar o estado de saúde da população, constituída de 200 voluntários não-fumantes e não-expostos, por motivo profissional, ao monóxido de carbono. Cada indivíduo respondeu um questionário para levantamento de dados relevantes à interpretação dos resultados. Os valores de referência foram expressos em termos da média ± desvio-padrão, intervalo de confiança 95% e valor de referência superior. A distribuição estatística dos resultados obtidos foi realizada para possibilitar sua comparação com grupos de trabalhadores, preferentemente à avaliação individual. RESULTADOS E CONCLUSÕES: O valor médio ± desvio-padrão para a carboxiemoglobina foi de 1,0 % ± 0,75; o intervalo de confiança 95%, entre 0,9 e 1,1 % e o valor de referência superior, de 2,5%. Através do teste t de Student (p < 0,05 não foi detectada diferença nos valores de acordo com o sexo, idade ou uso de bebidas alcoólicas.

  12. Para uma abordagem virtuosa do Jornalismo

    2012-06-01

    Full Text Available As últimas décadas têm favorecido o crescimento do interesse e dos estudos sobre a ética jornalística. No Brasil e em outras praças, as abordagens deste tema têm sido na maioria das vezes por um caráter deontológico ou utilitarista. Neste artigo, chamamos a atenção para uma perspectiva que privilegie as virtudes como pontos de partida para os debates acerca das condutas dos profissionais. Uma ética das virtudes remete a Aristóteles e aos estoicos, mas vem sendo retomada por autores mais contemporâneos, como Macintyre e Comte-Sponville, entre outros. No jornalismo, esta abordagem não é definitiva ou totalizante, mas contribui para uma compreensão mais ampla da discussão, chamando inclusive a atenção para recomendações éticas úteis, práticas e atuais.

Exige un esfuerzo de pariicipación y una capacidad crítica para facilitar el paso de una cultura de guerra a un cultura de paz. Se trata de ayudar a todos los ciudadanos a observar y reflexionar sobre el conjunto de la tierra y de quienes la habitan. De escuchar a los jóvenes y ser escuchado. La educación para la paz ha de ser considerada como contenido transversal de la educación. La situación actual, los conflictos interétnicos e interculturales , la exclusión y la marginalidad, las sociedades pobres y las ricas son cuestiones que reclaman una educación par la paz. De la cultura de imposición hemos de pasar a la cultura del diálogo y parti-cipación, solidaridad, compromiso, tolerancia y respeto. Es necesario construir otro mundo en el que podamos asegurar a nuestros descendientes el futuro.

    2012-01-01

    Full Text Available A partir de un breve repaso de las últimas reformas jurídicas al régimen electoral, tanto del Código Municipal como del Código Electoral, el artículo describe el nuevo sistema de financiamiento estatal que se ha dispuesto para apoyar económicamente a los partidos políticos que participan en los procesos electorales municipales y que, antes de la entrada en vigencia del nuevo Código Electoral, no existía. Haciendo énfasis en las características legales de ese nuevo sistema de financiamiento, a partir de las diferencias con el sistema de financiamiento estatal para los partidos políticos que participan en los procesos electorales nacionales, refiere la jurisprudencia del TSE en la materia, destacando que la primera resolución del Tribunal, que ordenó girar recursos del Estado, fue precisamente para un partido político inscrito en el nivel cantonal. Finalmente, partiendo de la tesis de que la ausencia de financiamiento estatal para los procesos electorales municipales constituyó una barrera para la profundización democrática costarricense, por lo que su inclusión representa un avance en el fortalecimiento de los derechos políticos de la ciudadanía, los autores concluyen con algunas recomendaciones de carácter legislativo, con el fin de fortalecer este régimen de financiamiento, principalmente por la vía de su sistematización y equiparación con el financiamiento para procesos electorales nacionales, con la expectativa de robustecer las plataformas partidarias y profundizar, así, nuestra cultura democrática en el nivel local. Se anexa cuadro con la lista de los partidos políticos a los que ya se ordenó girar el financiamiento indicado, que desglosa los montos totales y porcentuales, así como los montos que no pudieron ser liquidados y que regresan al erario.

  6. Technological properties of kaolin from Para

    International Nuclear Information System (INIS)

    The NE of the State of Para, is notable for its large reserves of kaolin for paper. Kaolin is a mineral composed of hydrated aluminum silicates such as kaolinite and halloysite. The exploitation of these reserves to generate products with higher commercial value, especially in the industries of adsorbents and catalysts, is what motivates the continuous study of technological properties of the Amazon kaolin's. Thus, this paper presents a technological characterization of a sample of kaolin from Para State by X-ray diffraction, SEM - scanning electron microscopy and infrared spectroscopy. The results of preliminary tests indicate that the sample consists for the most part by kaolinite present in low concentrations of quartz and anatase. (author)

  11. Thermal conductivities of ortho and para hydrogen

    International Nuclear Information System (INIS)

    The thermal conductivity of molecular hydrogen has been calculated using a Lennard-Jones potential added to a quadrupole-quadrupole interaction term. Large differences between ortho and para hydrogen were obtained particularly in the range about 200 K. Results for 'normal' hydrogen, here taken as a simple sum of results for the two components, were found to agree very well with recommended values for experiments on normal hydrogen. (Auth.)

    Full Text Available Muchos procesos industriales son de naturaleza multivariada dado que la calidad de un producto depende de más de una variable. El control multivariado de procesos captura la relación en las variables asociadas al proceso, si se ignora esta correlación y se utilizan gráficos de control univariados para cada variable por separado se puede concluir erróneamente acerca del estado del proceso. En variables continuas correlacionadas se han realizado muchas investigaciones, sin embargo se encuentran pocos trabajos que traten sobre atributos correlacionados. En este trabajo se comparan tres cartas de control para variables aleatorias binomiales bivariadas, correlacionadas entre sí, las cuales miden atributos. Las cartas son: La carta de Hotelling basada en la aproximación de la distribución binomial multivariada a la distribución normal multivariada. La carta MNP la cual es una extensión de las cartas univariadas, y la carta que es una metodología no paramétrica basada en el índice de profundidad de Mahalanobis. La comparación se hace vía simulación utilizando como medida de comparación, la longitud promedio de racha (ARL. Dentro del trabajo se presenta un ejemplo aplicado de las metodologías para construir cartas de control para variables binomiales bivariadas en una empresa de telecomunicaciones. De los resultados se aprecia, en términos generales, que la carta MNP es la mejor tanto en control como fuera de control.

Para la elaboración de la arquitectura se tuvo en cuenta los problemas en el flujo de trabajo actual, las deficiencias referentes a la distribución de roles, la inadecuada gestión del tiempo y la escasa utilización de componentes de software. Dicha arquitectura cuenta con una estructura formada por cinco entidades o componentes organizacionales las cuales son: la entidad Inteligencia, Gerencia de proyecto, Personas, Repositorio y Proceso. En cada una de ellas se organiza el trabajo a desarrollar a partir de procesos y actividades establecidas lo que ajusta el modelo a su objetivo fundamental para obtener productos con la calidad requerida. Estos procesos están concebidos para que sigan una línea de desarrollo que permita el buen funcionamiento entre las entidades. Es muy importante en este ámbito la comunicación, interacción e integración entre los componentes organizacionales ya que el trabajo de cada uno depende de los demás. Dicha arquitectura de factoría permite ser adaptado a cualquier organización o empresa teniendo en cuenta sus particularidades además de responsabilizar e identificar a los recursos humanos con su trabajo.

    Full Text Available A cirurgia de controle de danos é um conceito amplamente aceito atualmente entre os especialistas em trauma abdominal quando se trata de doentes gravemente traumatizados. Nestes pacientes a morte decorre, na maioria das vezes, da instalação da tríade letal (hipotermia, coagulopatia e acidose e não da incapacidade de reparar as graves lesões presentes. Nesta revisão, os autores abordam a tríade letal, em suas três fases, e enfatizam as medidas adotadas para preveni-las. Além de discutirem a indicação e o emprego da cirurgia para o controle de danos em seus vários estágios. A restauração dos padrões fisiológicos do doente na UTI, para que o mesmo possa ser submetido à operação definitiva e ao fechamento da cavidade abdominal, outro desafio no paciente traumatizado grave, também é discutida.

Un embate político sobre las alternativas al modelo neoliberal que se lograron instaurar en América Latina en los últimos 15 años. Este artículo contribuye a un debate que apenas comienza; una discusión en torno a los futuros posibles y al papel de los sectores progresistas y de izquierda en un continente que cada día cobra mayor importancia para los intereses de la geopolítica y la geoeconomía mundial. Para esto se empieza por analizar la coyuntura, obviamente con una perspectiva histórica, de tal manera que se posibilite entender el giro a la derecha o si se prefiere el retorno al modelo neoliberal. Luego el análisis tomará perspectivas de futuro, en donde los riesgos necesariamente aumentan para la Región por ser más visible y de mayor peso ante las presiones internacionales que ya ven en Sur América un actor importante. Por último, se presentan algunas reflexiones frente a los procesos económicos y políticos de cara al Buen Vivir en la América Latina.

Um desenho detalhado do novo amostrador é apresentado, com tôdas as indicações necessárias para que as pessoas ou organizações interessadas possam mandar construir novos modelos, em qualquer oficina mecânica bem aparelhada.In this paper is described a new soil sampler, specially designed for use in sampling Brazilian purple-soil series, which is known to present very peculiar physical properties. The sampler was developed as a result of the need to sample the soil frequently, for the purpose of maintaining the soil water balance in irrigation experiments, carried on field plots. This basic method of controlling water application in such experiments is being extensively used by the Seção de Irrigação, of the Instituto Agronômico. Detailed drawings ond some pictures are shown to allow interested persons or organizations, facing similar problems, to have models of the new sampler built in any good machine shop. The new sampler is very similar in its general characteristics to Veihmeyer's soil sampling tube, and was developed after the failure of this last sampler to operate properly in Brazilian purple-soils

    2006-11-01

    Full Text Available Au cours d'une campagne de plongée sur les escarpements qui bordent le bassin Ionien profond, des roches sédimentaires d'âge jurassique supérieur ont pu être récoltées dans l'escarpement de Malte, associées à des coulées de pillow-lavas. Les faunes d'Ammonites, typiquement mésogéennes, indiquent des âges oxfordien et tithonique. Elles peuvent correspondre à un milieu de dépôt profond. Les foraminifères recueillis dans les niveaux équivalents, riches en radiolaires, sclérites d'holothuries, fragments d'aptychus et rares Ostracodes, indiquent un âge oxfordien au sens large et un milieu de dépôt relativement profond. Cette série, relativement condensée et profonde, est comparable aux séries du même âge connues en Sicile. Elle s'oppose aux séries de calcaires de plate-forme néritiques du Trias-Lias inférieur qui constituent la base de la coupe. II y a donc eu un changement radical de milieu de sédimentation entre le Lias et le Callovo-Oxfordien, accompagné d'une distension révélée par un magmatisme important. During a diving campaing along the escarpments bordering the deep lonian Basin, Upper Jurassic sedimentary rocks were gathered from the Malta escarpment, associated with pillow-lava. Typically Mesogean ammonite fauna indicate Oxfordian and Tithonian ages. They correspond to a relatively deep deposition environment. The Foraminifers gathered in the equivalent levels, which proved to be rich in radiolarians, holothuroid sclerites, aptychus fragments and sparse ostracodes, indicate an Oxfordian age and a relatively deep deposition environnent. This relatively condensed and deep series can be compared with series of the same age known in Sicily. It is opposed to the Lower Triassic-Lias neritic platform limestone series making up the bottom of the section. A radical change in sedimentation thus occured between the Lias and the Callovo-Oxfordain, accompanied by a distension revealed by extensive magmatism.

    Full Text Available Des assemblages Pléistocène supérieur de Scléractiniaires ahermatypiques ont été prélevés sur l'escarpement de Malte-Syracuse à une profondeur d'eau en général supérieure à 2000 m, au cours de la campagne Escarmed 1 sur le N/O Jean Charcot. Les espèces les plus communes sont le corail Desmophyllum cristagalli et le bivalve Delectopecten vitreus, souvent encore en position de vie. La disparition des biocoenoses Desmophyllum-Delectopecten est probablement liée à une hausse de température provoquant une réduction du brassage vertical sur le fond et des conditions de quasi famine ; cependant une influence directe de la température sur la physiologie de tels organismes ne peut être écartée. Les calcaires coralliens reflètent une histoire sédimentologique complexe dont les principales étapes sont : la précipitation de carbonate par les organismes vivants, l'induration de la matrice vaseuse et le dépôt des oxydes Fe-Mn. Late Pleistocene scleractinian assemblages have been dredged along the Malta-Siracusa escarpment at a water depth generally > 2,000 m during the Escarmed 1 cruise of the R/V Jean Charcot. The most common species are the coral Desmophyllum cristagalli and the bivalve Delec-topecten vitreus often still in life position. The disappearance of the Desmophyllum-Delectopecten biocoenosis is probably related to an increase of temperature that lead to a reduced vertical mixing and conditions of quasi-starvation at the bottom: however, a more direct influx of the temperature on the physiology of such organisme can not be ruled out. The coral-bearing limestones reflect a complex sedimentological history whose main steps are: precipitation of carbonate by the living organisms, induration of the ooze matrix and deposition of Fe-Mn oxides.

El título explícito de la estrategia, Aprendizaje para Todos, es un claro reconocimiento de que, más allá de políticas centradas en el acceso, se debe hacer algo más para asegurar que la educación derive en experiencias positivas de aprendizaje. Sin embargo, como este artículo sostiene, las opciones de políticas explícitas y latentes en la Estrategia 2020 no son las más adecuadas para lograr el Aprendizaje para Todos. El artículo desarrolla tres tipos de argumentos al respecto. El primero se refiere al fuerte apego del Banco a un conocimiento disciplinario y un enfoque metodológico que es insuficiente para entender lo que aprenden los niños en la escuela y por qué. El segundo argumento se refiere al sesgo pro-mercado de la Estrategia por lo que respecta a la reforma del sector público y a nuevas formas de oferta educativa. En tercer lugar, el artículo señala las principales ausencias de la Estrategia, con especial atención a las omisiones relacionadas con la compleja relación entre educación y pobreza.

Aún avanzando por las sendas del siglo XXI es imposible vivir sin dedicarle atención priorizada a este proceso. Dentro de él un lugar primordial lo ocupa la habilidad de escuchar. Saber escuchar es una de las habilidades más importantes que debe tener un profesional e incluso cualquier persona común de la sociedad. En los últimos años los especialistas han venido dedicando una atención especial a esta habilidad, dándole un tratamiento relativamente independiente dentro de los estudios sobre el proceso de comunicación. En investigaciones realizadas sobre las habilidades que debe tener todo buen comunicador se ha determinado que la más necesaria y difícil de lograr es la de saber escuchar. Realmente pasamos más tiempo escuchando que hablando, pero no son muchos los que se pueden calificar como buenos oyentes. Los estudiosos del tema a nivel mundial coinciden también que desarrollar esta habilidad requiere, de una gran voluntad y disposición hacia el cambio de enfoques, conductas y formas de ver las cosas, porque solo hay una manera de lograrlo y es luchando desde “dentro” del individuo. En el trabajo se ofrecen diferentes opiniones y enfoques que pueden contribuir a desarrollar esta habilidad tan importante, para el trabajo profesional y para las relaciones interpersonales. Se enfatiza en los beneficios que reporta una buena escucha, qué entender por una buena escucha o escucha efectiva y las recomendaciones para lograr esa escucha efectiva.

  11. PARA EVITAR LA CONTAMINACIÓN AMBIENTAL

    Full Text Available El presente artículo se enmarca dentro de la caracterización del sistema de producción bovina del municipio de Utica (Cundinamarca y dentro de los problemas más importantes que lo afectan. Como resultado, el estudio identificó la escasez de alimento de buena calidad en épocas secas como la principal limitante del productor bovino del municipio. Aprovechando una ventaja presente en la zona, como es la elaboración de panela (proceso a través del cual resultan algunos subproductos, como bagazo y melote, que pueden ser utilizados como alternativa alimenticia para los bovinos en cualquier época del año, se planteó un experimento en el que se elaboraron bloques multinutricionales con base en dichos subproductos. El experimento se adelantó en una finca de un productor y se utilizaron 57 novillos cebús con edades entre los 11 y los 24 meses y pesos entre los 124 y los 463 kilogramos. Los animales se dividieron dos grupos que se mantuvieron en pasturas no manejadas. Al grupo experimental se le ofrecieron adicionalmente bloques multinutricionales. Los animales fueron examinados para comprobar su estado fisiológico, con el fin de determinar posibles inconvenientes sanitarios que pudieran afectar el ensayo. Se realizaron pesajes para medir las ganancias de peso en los dos grupos. Los resultados mostraron promedios de ganancias diarias de peso similares a Pr < 5%, donde fueron ligeramente superiores las del grupo alimentado con los bloques multinutricionales (0,848 vs. 0,769 kg animal/día. Los aportes más importantes del experimento fueron, primero, brindar una opción para que el productor pueda alimentar a sus animales en épocas de escasez y evitar que tenga que venderlos a bajos precios. El segundo aporte fue abrir la posibilidad de usar los productos de la elaboración de la panela, que en muchas ocasiones se convierten en desechos que no son usados y que contaminan las fuentes de agua, de una forma económicamente viable.

    Full Text Available As crianças nascem em uma época de grandes mudanças, tudo parece instantâneo. No mundo externo tudo se transforma rapidamente, mas em nosso mundo interior, o ritmo é outro. Necessitamos desenvolver a observação e o olhar interno, para nos relacionarmos de forma mais equilibrada e saudável com nós mesmos e com os outros. Ensinar crianças e adolescentes a relaxar, a meditar, a gostar de permanecer um pouco em silêncio, a cuidar tanto de si como dos outros, a acalmar o corpo e a mente é sem dúvida uma tarefa fundamental e imprescindível em nossa sociedade.  A prática de Yoga tem se mostrado uma maneira nova e eficiente para auxiliar no desenvolvimento físico e mental desta faixa etária.Vários trabalhos científicos têm sido publicados e sugerem que ensinar Yoga às crianças e aos jovens é uma atividade que traz benefícios à saúde tanto física como mental. Aparece também como uma forma promissora de terapia complementar, porém é recomendado que mais pesquisas sejam feitas para comprovar de forma mais clara e objetiva seus benefícios e aplicações. Na prática, observa-se nas crianças grande interesse, alegria e facilidade em aprender esta milenar arte indiana para integração de corpo e mente. Ouvir uma criança dizer: “Que silêncio gostoso...” ou “Parece que estou nas nuvens!” indicam que práticas contemplativas como Yoga são muito bem vindas na formação desta nova geração.
