    In the first two years of operation of the Fermi GBM, the 9-spacecraft Interplanetary Network (IPN) detected 158 GBM bursts with one or two distant spacecraft, and triangulated them to annuli or error boxes. Combining the IPN and GBM localizations leads to error boxes which are up to 4 orders of magnitude smaller than those of the GBM alone. These localizations comprise the IPN supplement to the GBM catalog, and they support a wide range of scientific investigations.

    as emoções envolvidas destacam a sensualidade e a feminilidade. As peças que compõem a terceira categoria tratam o corpo como confirmador da ação do produto. A interação é baseada em gestual reproduzido em imagens e as emoções estão associadas a prazer e praticidade. A quarta categoria apresentou significado diferente para o corpo feminino, tratando-o como objeto subordinado ao evento, comportado e feliz. Ao fim, ficou claro o tratamento do corpo como objeto que pode ser modificado, alterado, adequado de acordo com a intenção de seu proprietário, o que ajuda a explicar como o significado do corpo é construído socialmente e transferido do mundo culturalmente constituído até o espaço de consumo dos indivíduos.This paper aims to analyze the meanings that are attributed to the female body and are transferred through dietary supplements' advertisements. The body became a research theme for researchers interested in exploring the construction of meanings of consumption in many areas. Its expression as a commodity has already been pointed out by researchers as Malysse (2007 who proposed the objectification of the body and Goldenberg (2007 who built the concept of the body as a capital. According to MacCracken (2003, advertising works in the transfer of meaning from the culturally constituted world to the individuals. Nine ads were collected and analyzed through the advertising discourse analysis proposed by Pinto (2002. The functions of showing (mostração -the construction of the universe of discourse, interaction (interação - social and cultural linkages set and seduction (sedução - distribution of positive and negative affects were used as direction for researchers to seek ways to understand the meaning transfer of the female body through the ads.

A suplementação durante o período de acasalamento aumenta o desempenho reprodutivo de novilhas aos 14 meses de idade.The objective was to evaluate the performance of beef heifers until calving receiving different levels of supplementation on native pasture during the first breeding season, from 14 to 17 months: no supplementation; 3.5 g/kg of body weight; and 7.0 g/kg of body weight. Ninety-eight Charolais, Nellore and their crosses, with average initial weight of 255 kg, were used. Weight at the end and average daily weight gain during the supplementation period were higher for 7.0 g/kg of supplement heifers (322 and 0.701 kg compared to those with 3.5 g/kg of supplement (302 and 0.464 kg and heifers without supplementation (288 and 0.425 kg, which did not differ from each other. Body condition score at the end of the supplementation was different between the three treatments, being 3.03, 3.33 and 3.47 points for heifers without supplementation; 3.5 g/kg of body weight; and 7.0 g/kg of body weight, respectively. Pregnancy rate was significantly affected by supplementation level, being 35.0, 34.2 and 70.0%, respectively. Heifers of the two supplementation treatments had higher conception rate at the first half of the reproductive period. Average heifer ages at calving were of 785, 778 and 761 days, respectively. The average daily weight and body condition of the heifers of the two genetic groups were similar; however, the initial and final weight of the supplementation period was higher for Charolais bulls daughters, compared with Nellore bulls daughters, reflecting on the heat (68.8 vs. 38.2% and pregnancy (60.9 vs. 26.5% rates. Characteristics related to calving were not affected by the supplementation levels during the reproductive period. The supplementation during the first breeding season increases reproductive performance of heifers at 14 months of age.

    Full Text Available A glutamina é o aminoácido livre mais abundante no sangue e no músculo esquelético, bem como é o principal substrato energético para células de elevado turnover, como enterócitos e leucócitos. Adicionalmente, a glutamina representa o principal aminoácido transferido para o feto pela placenta e, juntamente com o glutamato, constituem os aminoácidos mais abundantes no leite materno. Todavia, bebês nascidos prematuramente sofrem interrupção abrupta do fornecimento placentário de glutamina, o que acarreta em dependência exclusiva da síntese endógena ou do fornecimento exógeno deste aminoácido. Aliado a isso, neonatos pré-termo (PT e com baixo peso ao nascer (BPN, freqüentemente, recebem apenas nutrição parenteral total nas primeiras semanas de vida, a qual não contém glutamina. Cabe ainda destacar que esses bebês possuem pouca massa muscular e, portanto, seus estoques de glutamina são limitados. Uma vez que neonatos PT e com BPN estão sujeitos a intenso crescimento e a inúmeros estresses fisiológicos, é possível que a glutamina seja um nutriente condicionalmente essencial nessa fase da vida, fato que estimulou a realização de estudos com a finalidade de avaliar os possíveis benefícios clínicos da suplementação enteral e parenteral com glutamina em neonatos PT e com BPN.Glutamine is the most abundant amino acid found in the blood and skeletal muscle, and is the principal energetic substrate for cells with a high turnover, such as enterocytes and leucocytes. Furthermore, glutamine is the most important amino acid that is passed to the foetus via the placenta, and together with glutamate, is the most abundant amino acid in maternal milk. Preterm infants suffer an abrupt interruption in the supply of glutamine via the placenta, which leads to an exclusive dependence on the endogenous synthesis or the exogenous supply of this amino acid.

O presente estudo verificou inicialmente o efeito da suplementação com L-glutamina e L-alanilL-glutamina sobre a resposta ao teste de hipersensibilidade do tipo tardio (HTT em ratos submetidos ao treinamento intenso em natação durante seis semanas. Posteriormente, foi avaliado o efeito dessas intervenções nutricionais sobre a contagem total e porcentual de leucócitos e concentração sérica de anticorpos IgG anti-albumina de soro bovino, em animais submetidos ao teste de exaustão e recuperados durante o período de 3 horas. Não houve efeito do treinamento e da suplementação sobre a resposta ao teste de HTT.

Initially, this study verified the effect of L-glutamine and L-alanyl-L-glutamine supplementation on the response to delayed-type hypersensitivity test (DTH in rats submitted to intense swimming training for six weeks. Later on, we assessed the effect of these nutritional interventions on total and differential white blood cell counts and on concentration of anti-bovine serum albumin IgG antibodies, in animals submitted to exhaustion test and a three-hour recovery period. There was no effect of training and supplementation on the response to DTH. Supplemented animals presented greatest plasma glutamine concentration (p<0.05, though this increase in glutaminemia did not interfere on the serum IgG antibody concentration. The recovery period after intense exercise resulted in decreased glutaminemia as compared with the values obtained immediately after exhaustion test (p<0.05.

    dias pré-acasalamento proporciona maior taxa de prenhez em novilhas de corte aos 13/15 meses de idade.The effect was assessed of pre-mating supplementary feeding on the reproductive performance of 13-15 month old beef heifers. Eighty-nine heifers were used with a mean age of 12 months and mean body weight (BW of 242 kg from three herds Aberdeen Angus heifers from the Santa Cecilia and Capitao Rodrigo ranches and crossbred Aberdeen Angus heifers in a feeding system of only grazing pasture or supplemented heifers on pasture with milled corn grain. The supplement was offered daily at the proportion of 0.7% of the BW for 29 days on Oats (Avena strigosa Schreb and annual Ryegrass (Lolium multiflorum Lam cultivated pastures and 19 days on natural pasture. The grazing was continuous with variable stocking rate. The variables analyzed were: body weight, body condition, average daily live weight gain, body condition gain, percentage of pubescent heifers, pregnancy rate and conception order. There was no feeding systems ×herd interaction. During the pre-mating, the supplemented heifers had greater ADG, 0.800 kg, compared to those without supplementation, 0.658 kg. During the mating period, the heifers lost weight, mean of -0.104 kg/day. The variables body weight and body condition did not differ at the beginning of the mating period mean of 277 kg and 3.6 points, respectively. The supplemented heifers showed higher percentage of pubescent heifers (78% and higher pregnancy rate (47%. There was herd ×period interaction for body weight. The body weight variation was quadratic for the three herds. Crossbred heifers always had greater body weight compared to the Santa Cecília Angus heifers. Capitão Rodrigo Angus heifers had higher higher percentage of pubescent heifers (80% and PR (48%. Energy supplementation during 48 days pre-mating promoted higher pregnancy rate in 13 to 15 month old beef heifers.

    Full Text Available Estudos recentes têm sugerido que a suplementação de creatina é capaz de modular a homeostase da glicose, aumentando sua captação pelos tecidos periféricos. O objetivo deste trabalho foi investigar o efeito da suplementação de creatina na tolerância à glicose e no conteúdo de glicogênio muscular e hepático em ratos submetidos ou não à atividade física por quatro e oito semanas. Ratos Wistar foram divididos em dois grupos: quatro e oito semanas de intervenção. Posteriormente, cada grupo foi subdividido em quatro subgrupos, de acordo com a ingestão do suplemento e o treinamento: controle cedentário, controle treinado, suplementado sedentário e suplementado treinado. Os animais tiveram livre acesso à água e ração; o grupo suplementado teve 2% de sua ração sob a forma de creatina monoidratada. Os grupos exercitados nadaram 40 minutos por dia, quatro dias por semana, com carga entre 2 e 5% do seu peso amarrado ao peito. Após quatro e oito semanas, o teste oral de tolerância à glicose e as dosagens de glicogênio muscular e hepático foram realizadas. Não foram observadas diferenças significativas entre os grupos no teste de tolerância oral à glicose e no conteúdo de glicogênio muscular e hepático. Este estudo mostrou que a suplementação de creatina não exerceu influência na tolerância à glicose nem nas concentrações de glicogênio em ratos submetidos ou não à atividade física por quatro ou oito semanas.Recently, studies have suggested that creatine supplementation can modulate glucose homeostasis by increasing glucose uptake in peripheral tissues.

Aos 35 dias de idade, duas aves de cada tratamento foram transferidas para gaiolas de metabolismo para coleta total das excretas durante quatro dias. O consumo de ração e o ganho de peso foram de 12,8 e 16% respectivamente, e superiores (P0,05 para o consumo de ração, ganho de peso e conversão alimentar em razão dos níveis crescentes de cálcio nas rações. A digestibilidade da matéria seca foi melhor com o nível de 0,88% de cálcio, e a maior retenção de nitrogênio foi obtida com 0,70% de cálcio na ração suplementadas com fitase. Conclui-se que o aumento dos níveis de cálcio em rações suplementadas com fitase para frangos de corte dos 22 aos 42 dias de idade não afeta o desempenho dos mesmos, e níveis muito baixos de cálcio reduzem a digestibilidade da matéria seca e retenção de nitrogênio das rações.With the objective of evaluating the levels of calcium in the ration supplemented with phytase for broiler chickens from 22 to 42 days old, one experiment was conducted by using a total of 600 chickens of 22 days old Hubardb-MPK strain, distributed in a completely randomized design, in five two factorial arrangement (levels of calcium of the diet x sexes, with three replicates of 20 birds per plot.

    Prolyl peptidases of the MEROPS S28 family are of particular interest because they are key enzymes in the digestion of proline-rich peptides. A BLAST analysis of the Aspergillus oryzae genome revealed sequences coding for four proteases of the S28 family. Three of these proteases, AoS28A, AoS28B, and AoS28C, were previously characterized as acidic prolyl endopeptidases. The fourth protease, AoS28D, showed high sequence divergence with other S28 proteases and belongs to a phylogenetically distinct cluster together with orthologous proteases from other Aspergillus species. The objective of the present paper was to characterize AoS28D protease in terms of substrate specificity and activity. AoS28D produced by gene overexpression in A. oryzae and in Pichia pastoris was a 70-kDa glycoprotein with a 10-kDa sugar moiety. In contrast with other S28 proteases, AoS28D did not hydrolyze internal Pro-Xaa bonds of several tested peptides. Similarly, to human lysosomal Pro-Xaa carboxypeptidase, AoS28D demonstrated selectivity for cleaving C-terminal Pro-Xaa bonds which are resistant to carboxypeptidases of the S10 family concomitantly secreted by A. oryzae. Therefore, AoS28D could act in synergy with these enzymes during sequential degradation of a peptide from its C-terminus.

    Full Text Available A partir de uma leitura da peça Calígula, elaborada entre 1941 e 1943, procurar-se-á contribuir na restituição das preocupações éticas, políticas e filosóficas em cena no teatro de Albert Camus, analisando o sentido de sua expressão teatral no contexto de dois combates,ao niilismo filosófico e ao totalitarismo político de seu tempo. Observaremos em Calígula um importante registro do amadurecimento das leituras de duas heranças filosóficas relevantes na formação intelectual de Camus, Nietzsche e Heráclito, à luz da experiência do totalitarismo, observando e ressaltando com isso a amplitude de seu intertexto filosófico e a importância do aporte ético e político de Camus como pensador multifacetado, engajado nos enfrentamentos históricos e solicitações críticas de seu tempo.

As rações experimentais e a água foram fornecidas à vontade até o final do experimento, quando os animais atingiram o peso médio de 60,2 kg. A temperatura média no interior da sala foi mantida em 22,0ºC e a umidade relativa média em 82,8%, correspondendo a um índice de temperatura de globo e umidade (ITGU de 69,2. A redução do nível de PB da ração influenciou o ganho de peso (GP dos animais; aqueles que consumiram a ração com 17% de PB apresentaram redução significativa no GP em relação aos que receberam as rações com 15 e 14% de PB. O consumo de ração e a conversão alimentar não foram influenciados pelos tratamentos. A redução do nível de PB aumentou as deposições de gordura e de proteína na carcaça e levou à diminuição da excreção de nitrogênio total. O nível de PB da ração para suínos machos dos 30 aos 60 kg mantidos em ambiente termoneutro pode ser reduzido de 17 para 13%, sem influenciar negativamente o desempenho, desde que as rações sejam devidamente suplementadas com aminoácidos essenciais limitantes.An study was conducted to evaluate the influence of reduction of crude protein (CP levels and amino acid supplementation in diets on the performance of castrated swines (Landracex Large White maintained in a termoneutral environment.

  8. Aerosol Observing System (AOS) Handbook

    Energy Technology Data Exchange (ETDEWEB)

    Jefferson, A

    2011-01-17

    The Aerosol Observing System (AOS) is a suite of in situ surface measurements of aerosol optical and cloud-forming properties. The instruments measure aerosol properties that influence the earth’s radiative balance. The primary optical measurements are those of the aerosol scattering and absorption coefficients as a function of particle size and radiation wavelength and cloud condensation nuclei (CCN) measurements as a function of percent supersaturation. Additional measurements include those of the particle number concentration and scattering hygroscopic growth. Aerosol optical measurements are useful for calculating parameters used in radiative forcing calculations such as the aerosol single-scattering albedo, asymmetry parameter, mass scattering efficiency, and hygroscopic growth. CCN measurements are important in cloud microphysical models to predict droplet formation.

    Law, Nicholas M.; Ziegler, Carl; Tokovinin, Andrei

    2016-08-01

    We present plans for SRAO, the first Southern Robotic AO system. SRAO will use AO-assisted speckle imaging and Robo-AO-heritage high efficiency observing to confirm and characterize thousands of planet candidates produced by major new transit surveys like TESS, and is the first AO system to be capable of building a comprehensive several-thousand-target multiplicity survey at sub-AU scales across the main sequence. We will also describe results from Robo-AO, the first robotic LGS-AO system. Robo-AO has observed tens of thousands of Northern targets, often using a similar speckle or Lucky-Imaging assisted mode. SRAO will be a moderate-order natural-guide-star adaptive optics system which uses an innovative photoncounting wavefront sensor and EMCCD speckle-imaging camera to guide on faint stars with the 4.1m SOAR telescope. The system will produce diffraction-limited imaging in the NIR on targets as faint as mν = 16. In AO-assisted speckle imaging mode the system will attain the 30-mas visible diffraction limit on targets at least as faint as mν = 17. The system will be the first Southern hemisphere robotic adaptive optics system, with overheads an order of magnitude smaller than comparable systems. Using Robo-AO's proven robotic AO software, SRAO will be capable of observing overheads on sub-minute scales, allowing the observation of at least 200 targets per night. SRAO will attain three times the angular resolution of the Palomar Robo-AO system in the visible.

Para determinar a sensibilidade da flor ao etileno, hastes foram cortadas e colocadas em câmaras herméticas e em seguida tratadas por 24 horas com diferentes concentrações de etileno variando de 0,0; 0,1; 1,0; 10; 100 e 1000 µL L-1do ar no interior da câmara. A rosa teve a vida pós-colheita reduzida pelo etileno, quando exposta a concentração igual ou superior a 10 µL L-1 de etileno. As flores tratadas com no mínimo de 10 µL L-1de etileno desenvolveram necrose, murcha e abscisão prematura das pétalas ainda túrgidas. As concentrações de 0,1 e 1,0 µL L-1de etileno estimularam a abertura do botão floral durante o período de 24 horas de exposição ao etileno, sem no entanto, reduzir a vida pós-colheita. A rosa 'Osiana' pode ser classificada como uma cultivar sensível ao etileno e a concentração influência os processos estimulados.

    We analyzed close to 7,000 observations from Robo-AO’s field M dwarf survey taken on the 2.1m Kitt Peak telescope. Results will help determine the total multiplicity fraction and multiplicity functions of M dwarfs, which are crucial steps towards understanding their evolution and formation mechanics. Through its robotic, laser-guided, and automated system, the Robo-AO instrument has yielded the largest adaptive-optics M dwarf survey to date. I developed a graphical user interface to quickly analyze this data. Initial data analysis included assessing data quality, checking the result from Robo-AO’s automatic reduction pipeline, and determining existence as well as the relative position of companions through a visual inspection. This program can be applied to other datasets and was successfully tested by re-analyzing observations from a separate Robo-AO survey. After a conservative initial cut for quality, over 350 companions were found within 4” of a primary star out of 2,746 high quality Robo-AO M dwarf observations, including four triple systems. Further observations were done with the Keck II telescope by using its NIRC2 imager to follow up on ten select targets for the existence and physical association of companions. Future research will yield insights into low-mass stellar formation and provide a database of nearby M dwarf multiples that will potentially assist ongoing and future surveys for planets around these stars, such as the NASA TESS mission.

    Full Text Available Na literatura internacional são encontradas várias escalas para medir valores relativos ao trabalho, porém a maioria apresenta problemas com relação à definição do conceito ou a falta de integração com os modelos teóricos sobre valores pessoais. No Brasil foram encontrados dois instrumentos, um não foi validado para a população brasileira e o outro foi validado para uma população de baixa escolaridade. Foi objetivo do presente estudo desenvolver e validar uma Escala de Valores relativos ao Trabalho. Para o desenvolvimento da EVT foi realizado um levantamento de instrumentos anteriores e foram entrevistados trabalhadores. Após a análise de juízes e validação semântica, o instrumento foi respondido por 394 pessoas. A análise fatorial apontou para quatro fatores: Realização no trabalho, Relações sociais, Prestígio e Estabilidade. O instrumento após validação é composto por 45 itens. Os resultados corroboraram o modelo teórico previsto e conclui-se que a escala foi devidamente estabelecida e pode ser utilizada para pesquisa e diagnóstico.

Casos anteriores evidenciaram necrose tubular aguda e nefrite intersticial com poucos depósitos de cálcio no interstício renal. Nesse caso, encontramos nefrocalcinose acentuada associada à nefroesclerose. O objetivo deste estudo é relatar a ocorrência de injúria renal aguda com nefrocalcinose associada ao uso de esteroide anabolizante e oferecer uma revisão do assunto.

    Background: Consumers increasingly choose food supplements in addition to their diet. Research on supplement users finds they are likely to be female, older and well-educated; Furthermore, supplement users are often characterised as being especially health-oriented, an observation which is termed...... the ‘inverse supplement hypothesis’. However, results are dependent on the substance in question. Little is known so far about botanicals in general, and more specifically, little is known about resveratrol. The psychographic variables of food supplement users are yet relatively underexplored. By comparing US...... and Danish respondents, we aimed to identify whether sociodemographic variables, health status, health beliefs and behaviour and interest in food aspects specifically relevant to resveratrol (e.g., naturalness, indulgence, and Mediterranean food) explain favourable attitudes and adoption intentions toward...

    Physical training and competition in football markedly increase the need for macro- and micronutrient intake. This requirement can generally be met by dietary management without the need for dietary supplements. In fact, the efficacy of most supplements available on the market is unproven. In addition, players must be cautious of inadequate product labelling and supplement impurities that may cause a positive drug test. Nonetheless, a number of dietary supplements may beneficially affect football performance. A high endurance capacity is a prerequisite for optimal match performance, particularly if extra time is played. In this context, the potential of low-dose caffeine ingestion (2 - 5 mg . kg body mass(-1)) to enhance endurance performance is well established. However, in the case of football, care must be taken not to overdose because visual information processing might be impaired. Scoring and preventing goals as a rule requires production of high power output. Dietary creatine supplementation (loading dose: 15 - 20 g . day(-1), 4 - 5 days; maintenance dose: 2 - 5 g g . day(-1)) has been found to increase muscle power output, especially during intermittent sprint exercises. Furthermore, creatine intake can augment muscle adaptations to resistance training. Team success and performance also depend on player availability, and thus injury prevention and health maintenance. Glucosamine or chondroitin may be useful in the treatment of joint pain and osteoarthritis, but there is no evidence to support the view that the administration of these supplements will be preventative. Ephedra-containing weight-loss cocktails should certainly be avoided due to reported adverse health effects and positive doping outcomes. Finally, the efficacy of antioxidant or vitamin C intake in excess of the normal recommended dietary dose is equivocal. Responses to dietary supplements can vary substantially between individuals, and therefore the ingestion of any supplement must be assessed

  7. Photon counting arrays for AO wavefront sensors

    2005-01-01

    Future wavefront sensors for AO on large telescopes will require a large number of pixels and must operate at high frame rates. Unfortunately for CCDs, there is a readout noise penalty for operating faster, and this noise can add up rather quickly when considering the number of pixels required for the extended shape of a sodium laser guide star observed with a large telescope. Imaging photon counting detectors have zero readout noise and many pixels, but have suffered in the past with low QE at the longer wavelengths (>500 nm). Recent developments in GaAs photocathode technology, CMOS ASIC readouts and FPGA processing electronics have resulted in noiseless WFS detector designs that are competitive with silicon array detectors, though at ~40% the QE of CCDs. We review noiseless array detectors and compare their centroiding performance with CCDs using the best available characteristics of each. We show that for sub-aperture binning of 6x6 and greater that noiseless detectors have a smaller centroid error at flu...

So macht der Zwang, in einem Verfahren zu entscheiden und zu begründen, zugleich deutlich, dass jede Form der Entscheidung unangemessen, unbegründet und in ganz anderer Weise neu herzustellen ist. Das ist das juridische Supplement im Geiste von Jacques Derrida. Supplementiert wird die Wahrheit des Rechts in anderen Medien: in Drama, Film und Literatur etwa. Dort wird in Szene gesetzt, was in der real erlebbaren Rechtswelt nicht wirklich erlebt werden kann, was aber doch – wie kein Amtsträger bestreiten würde – zum Verfahrensergebnis gehört. Judge Adam, Advocate “Liebling” and William, the Detective. Legal practice is based on something that is not only an integral part of it and complements it, but also puts it into question generally. The compulsion to argue and reach decisions in a legal trial clarifies simultaneously that all forms of decision are inapproprate, unreasonable, and can be recreated in an entirely new manner [to suit the needs of the trial]. This is the legalistic supplement in the spirit of Jacques Derrida. The legal truth is supplemented by other forms of media such as drama, film and literature, which are able to stage scenes that cannot be experienced in a real life legal world, but – as no legal official would deny – are an integral part of the trial and verdict procedure.

  9. Weight Loss Nutritional Supplements

    Science.gov (United States)

    Eckerson, Joan M.

    Obesity has reached what may be considered epidemic proportions in the United States, not only for adults but for children. Because of the medical implications and health care costs associated with obesity, as well as the negative social and psychological impacts, many individuals turn to nonprescription nutritional weight loss supplements hoping for a quick fix, and the weight loss industry has responded by offering a variety of products that generates billions of dollars each year in sales. Most nutritional weight loss supplements are purported to work by increasing energy expenditure, modulating carbohydrate or fat metabolism, increasing satiety, inducing diuresis, or blocking fat absorption. To review the literally hundreds of nutritional weight loss supplements available on the market today is well beyond the scope of this chapter. Therefore, several of the most commonly used supplements were selected for critical review, and practical recommendations are provided based on the findings of well controlled, randomized clinical trials that examined their efficacy. In most cases, the nutritional supplements reviewed either elicited no meaningful effect or resulted in changes in body weight and composition that are similar to what occurs through a restricted diet and exercise program. Although there is some evidence to suggest that herbal forms of ephedrine, such as ma huang, combined with caffeine or caffeine and aspirin (i.e., ECA stack) is effective for inducing moderate weight loss in overweight adults, because of the recent ban on ephedra manufacturers must now use ephedra-free ingredients, such as bitter orange, which do not appear to be as effective. The dietary fiber, glucomannan, also appears to hold some promise as a possible treatment for weight loss, but other related forms of dietary fiber, including guar gum and psyllium, are ineffective.

  12. Tyrosine supplementation for phenylketonuria.

    Science.gov (United States)

    Webster, Diana; Wildgoose, Joanne

    2013-06-05

    Phenylketonuria is an inherited disease for which the main treatment is the dietary restriction of the amino acid phenylalanine. The diet has to be initiated in the neonatal period to prevent or reduce mental handicap. However, the diet is very restrictive and unpalatable and can be difficult to follow. A deficiency of the amino acid tyrosine has been suggested as a cause of some of the neuropsychological problems exhibited in phenylketonuria. Therefore, this review aims to assess the efficacy of tyrosine supplementation for phenylketonuria. To assess the effects of tyrosine supplementation alongside or instead of a phenylalanine-restricted diet for people with phenylketonuria, who commenced on diet at diagnosis and either continued on the diet or relaxed the diet later in life. To assess the evidence that tyrosine supplementation alongside, or instead of a phenylalanine-restricted diet improves intelligence, neuropsychological performance, growth and nutritional status, mortality rate and quality of life. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Trials Register which is comprised of references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. Additional studies were identified from handsearches of the Journal of Inherited Metabolic Disease (from inception in 1978 to 1998). The manufacturers of prescribable dietary products used in the treatment of phenylketonuria were also contacted for further references.Date of the most recent search of the Group's Inborn Errors of Metabolism Trials Register: 28 June 2012.

    Cooke, Matt; Cribb, Paul J.

    Few supplement combinations that are marketed to athletes are supported by scientific evidence of their effectiveness. Quite often, under the rigor of scientific investigation, the patented combination fails to provide any greater benefit than a group given the active (generic) ingredient. The focus of this chapter is supplement combinations and dosing strategies that are effective at promoting an acute physiological response that may improve/enhance exercise performance or influence chronic adaptations desired from training. In recent years, there has been a particular focus on two nutritional ergogenic aids—creatine monohydrate and protein/amino acids—in combination with specific nutrients in an effort to augment or add to their already established independent ergogenic effects. These combinations and others are discussed in this chapter.

    2010-01-01

    The Consultative Committee for Space Data Systems (CCSDS) Advanced Orbiting Systems (AOS) space data link protocol provides a framing layer between channel coding such as LDPC (low-density parity-check) and higher-layer link multiplexing protocols such as CCSDS Encapsulation Service, which is described in the following article. Recent advancement in RF modem technology has allowed multi-megabit transmission over space links. With this increase in data rate, the CCSDS AOS protocol implementation needs to be optimized to both reduce energy consumption and operate at a high rate.

    Molecule dynamics (MD) simulation, a molecular-level method, was applied to predict the damping properties of AO-60/polyacrylate rubber (AO-60/ACM) composites before experimental measures were performed. MD simulation results revealed that two types of hydrogen bond, namely, type A (AO-60) -OH•••O=C- (ACM), type B (AO-60) - OH•••O=C- (AO-60) were formed. Then, the AO-60/ACM composites were fabricated and tested to verify the accuracy of the MD simulation through dynamic mechanical thermal analysis (DMTA). DMTA results showed that the introduction of AO-60 could remarkably improve the damping properties of the composites, including the increase of glass transition temperature (Tg) alongside with the loss factor (tan δ), also indicating the AO-60/ACM(98/100) had the best damping performance amongst the composites which verified by the experimental.

    Many specialists note that the food offered today - as a result of very complex technological processing - is devoid of many components that are important for the organism and the shortages have to be supplemented. The simplest for it is to consume diet supplements that provide the missing element in a concentrated form. In accordance with the applicable law, medicinal products include all substances or mixtures of substances that are attributed with properties of preventing or treating diseases with humans or animals. Permits to admit supplements to the market are issued by the Chief Sanitary Inspector and the related authorities; permits for medicines are issued by the Chief Pharmaceutical Inspector and the Office for Registration of Medicinal Products, Medical Devices and Biocidal Products. Therefore, admittance of a supplement to the market is less costly and time consuming_than admittance of a medicine. Supplements and medicines may contain the same component but medicines will have a larger concentration than supplements. Sale of supplements at drug stores and in the form of tablets, capsules, liquids or powders makes consumer often confusing supplements with medicines. Now there are no normative documents specifying limits of microbiological impurities in diet supplements. In Polish legislation, diet supplements are subject to legal acts concerning food. Medicines have to comply with microbiological purity requirements specified in the Polish Pharmacopeia. As evidenced with the completed tests, the proportion of diet supplement samples with microbiological impurities is 6.5%. Sales of diet supplements have been growing each year, they are consumed by healthy people but also people with immunology deficiencies and by children and therefore consumers must be certain that they buy safe products.

  3. Issues in Nutrition: Dietary Supplements.

    The majority of American adults report use of one or more dietary supplements every day or occasionally. The Dietary Supplement Health and Education Act of 1994 defines dietary supplements and regulates their manufacture and distribution. One of the most commonly used supplements is vitamin D. Measurement of serum levels of vitamin D must be undertaken with the caveats that different laboratories define normal levels differently, and that there is rarely a clinical correlation with the actual level. Patients should understand that supplements should not be used to excess, as there are toxicities and other adverse effects associated with most of them. There currently is considerable research being performed on probiotics and how the gut microbiome affects health and disease states. Protein supplements may be useful in reducing mortality rates in elderly patients but they do not appear to increase quality of life. If used, protein supplements should contain essential amino acids. Casein and whey supplements, derived from dairy sources, help transport essential amino acids to tissues. Although there have been many studies investigating the role of vitamin supplements in disease prevention, there have been few conclusive positive results.

    2011-01-01

    Lead present in calcium supplements is of grave concern as some lead levels have been measured up to the extent of regulatory limit set by the United States. Calcium supplements inevitably get contaminated with lead as both are naturally occurring elements. Therefore, it is imperative to indicate its level in these supplements in order to create awareness among consumers. In this study, a sophisticated analytical technique, atomic absorption spectrometry was used to analyze Pb contents in 27 commonly consumed Ca supplements manufactured by different national and multinational companies. The daily intake of lead through these supplements was calculated. Only 10% of the calcium supplements analyzed met the criteria of acceptable Pb levels (1.5 mu g/daily dose) in supplements/consumer products set by the United States. It was also found that Pb intake was highest in chelated calcium supplements 28.5 mu g/daily dose, whereas lowest 0.47 mu g/daily dose through calcium supplements with vitamin D formulation. In order to validate our results from the study conducted, IAEA-certified reference material (animal bone, H-5) was analyzed for its Pb levels. The levels of Pb determined were quite in good agreement with the certified values. (author)

    Supplementation is a key component in bodybuilding and is increasingly being used by amateur weight lifters and enthusiasts to build their ideal bodies. Bodybuilding supplements are advertised to provide nutrients needed to help optimise muscle building but they can contain high amounts of sugar. Supplement users are consuming these products, while not being aware of their high sugar content, putting them at a higher risk of developing dental caries. It is important for dental professionals to recognise the increased risk for supplement users and to raise awareness, provide appropriate preventative advice and be knowledgeable of alternative products to help bodybuilders reach their goals, without increasing the risk of dental caries.

Embora associada a consequências negativas, pois muitas patologias físicas e mentais são desencadeadas por exposição crônica a estressores, esta resposta é indispensável para sobrevivencia do indivíduo e é extremamente adaptativa quando ativada de forma aguda. Na parte I desta revisão foram abordados os conceitos de homestase e alostase e os sistemas fisiológicos ativados durante a resposta ao estresse. Na parte II serão discutidos fatores que modulam a resposta ao estresse tais como sexo, temperamento, períodos críticos do desenvolvimento e a presença ou ausência de suporte social. A interação entre os fatores genéticos e ambientais gera os perfis da resposta psicofisiológica que caracterizam os fenótipos de susceptibilidade e resiliência frente aos estressores e sua relação com uma patologia mental cada vez mais presente na sociedade moderna, o transtorno de estresse pós-traumático.

    The major part of food consists of chemical compounds that can be used for energy production, biological synthesis, or maintenance of metabolic processes by the host. These components are defined as nutrients, and can be categorized into macronutrients (proteins, carbohydrates, triglycerides......, and alcohol), minerals, and micronutrients. The latter category comprises 13 vitamins and a hand full of trace elements. Many micronutrients are used as food supplements and are ingested at doses exceeding the amounts that can be consumed along with food by a factor of 10–100. Both macro- and micronutrients...... can interact with enzyme systems related to xenobiotic metabolism either by regulation of their expression or direct interference with their enzymatic activity. During food consumption, we consume a wide range of xenobiotics along with the consumable food, either as an original part of the food (e...

  15. Holocene Evolution of Qing'ao Embayment, Southern China

    2012-12-01

    The Holocene evolution of the Qing'ao embayment, Nan'ao Island, southern China, is primarily the result of the interaction of tectonic activity, climate variation and changes in relative sea level. Characterizing the evolutionary history of the relatively small Qing'ao embayment during the Holocene will help improve our understanding of the driving mechanisms of coastal evolution in the area. To reconstruct the Holocene evolution history we analyzed the grain size, loss on ignition (LOI) and carbonate content of modern and core samples. Modern environmental analogs were examined in surface samples ranging from the coastal sand dunes through to offshore. The results of these modern samples suggest that dune sand (mean size of ~2.33Phi) are slightly finer than beach sand (mean size of 2.13Phi), and nearshore sediment is much coarser than offshore sediment (mean size of 5.90Phi). This modern analogs were then applied to 8 percussion cores from the Qing'ao embayment. A chronological framework obtained from 11 radiocarbon samples suggests that the embayment started to accept deposition since early Holocene, ~8500 cal. yr. BP. Three main phases of Holocene evolution were identified. A basin wide shell-rich sand sheet forms the basal Holocene facies and overlies clay rich presumably Pleistocene sediments or bedrock. This facies records an initial sedimentation phase associated with the early Holocene transgression into the embayment (~8500-6000 cal. yr. BP). The basal facies grades upward to a mixed sandy-mud facies which includes lagoonal clayey-silts, flood tide delta sands and records an estuarine phase lasting from ~6000-1000 cal. yr. BP that appears coincident with falling regional sea levels. Coincident with the estuarine phase is a period of coastal dune building recorded as yet undated massive sands that are found in the upper fill. Toward the end of the estuarine phase it is apparent that dune migration has restricted the lagoon entrance and that this was

  16. Nutritional Supplements for Endurance Athletes

    Science.gov (United States)

    Rasmussen, Christopher J.

    Athletes engaged in heavy endurance training often seek additional nutritional strategies to help maximize performance. Specific nutritional supplements exist to combat certain factors that limit performance beginning with a sound everyday diet. Research has further demonstrated that safe, effective, legal supplements are in fact available for today's endurance athletes. Several of these supplements are marketed not only to aid performance but also to combat the immunosuppressive effects of intense endurance training. It is imperative for each athlete to research the legality of certain supplements for their specific sport or event. Once the legality has been established, it is often up to each individual athlete to decipher the ethics involved with ingesting nutritional supplements with the sole intent of improving performance.

Magnetic nanoparticles-metal-organic frameworks (MMOFs hybrid materials can facilitate facile removal of MOFs from solutions. In this report, we report the synthesis of Fe3O4@UiO-66 by encapsulation and simulated the drug loading and release by studying the adsorption and release of AO7. Thus, we loaded these MMOFs with AO7 and found that they were able to trigger and control its release by simply applying an external magnetic field. The magnetic field heats the magnets in the MOF, which causes the load to burst from the framework.

Temos aí um retrato, imagem subtraída ilicitamente ao seu dono: escrita, representação. Temos também uma narrativa, escrita do retrato, representação da representação. Este artigo pretende mostrar como Guimarães Rosa manipula as ambiguidades da linguagem literária, levando-a além dos limites da representação, explorando seu fascínio, seu saber, que não é da ordem da compreensão. O cavalo e seu retrato fazem refletir sobre a literatura, sobre seu excesso de verdade que compõe sua mentira. Ao escrever o cavalo e seu retrato, o texto não consegue fixar nenhuma verdade, apenas imagens fugidias que compõem recapítulos: há sempre um escrito a se sobrepor a outro, sem determinar onde está o verdadeiro, onde está o que o nega, a remeter o olhar ao reino da fascinação, onde a imagem perde o valor de significação para se tornar pura paixão da indeterminação, da indiferença.

    Background The primary objective of this study was to test interobserver reliability when classifying fractures by consensus by AO types and groups among a large international group of surgeons. Secondarily, we assessed the difference in inter- and intraobserver agreement of the AO classification in relation to geographical location, level of training, and subspecialty. Methods A randomized set of radiographic and computed tomographic images from a consecutive series of 96 distal radius fractures (DRFs), treated between October 2010 and April 2013, was classified using an electronic web-based portal by an invited group of participants on two occasions. Results Interobserver reliability was substantial when classifying AO type A fractures but fair and moderate for type B and C fractures, respectively. No difference was observed by location, except for an apparent difference between participants from India and Australia classifying type B fractures. No statistically significant associations were observed comparing interobserver agreement by level of training and no differences were shown comparing subspecialties. Intra-rater reproducibility was “substantial” for fracture types and “fair” for fracture groups with no difference accounting for location, training level, or specialty. Conclusion Improved definition of reliability and reproducibility of this classification may be achieved using large international groups of raters, empowering decision making on which system to utilize.

    Previous secondary ion mass spectrometry (SIMS) studies of extended impact features from LDEF capture cell experiment AO187-2 showed that it is possible to distinguish natural and man-made particle impacts based on the chemical composition of projectile residues. The same measurement technique has now been applied to specially prepared gold target impacts from experiment AO187-1 in order to identify the origins of projectiles that left deposits too thin to be analyzed by conventional energy-dispersive x-ray (EDX) spectroscopy. The results indicate that SIMS may be the method of choice for the analysis of impact deposits on a variety of sample surfaces.

    Full Text Available The effector repertoire of the olive pathogen P. savastanoi pv. savastanoi NCPPB 3335 includes two members of the HopAO effector family, one of the most diverse T3E families of the P. syringae complex. The study described here explores the phylogeny of these dissimilar members, HopAO1 and HopAO2, among the complex and reveals their activities as immune defense suppressors. Although HopAO1 is predominantly encoded by phylogroup 3 strains isolated from woody organs of woody hosts, both HopAO1 and HopAO2 are phylogenetically clustered according to the woody/herbaceous nature of their host of isolation, suggesting host specialization of the HopAO family across the P. syringae complex. HopAO1 and HopAO2 translocate into plant cells and show hrpL-dependent expression, which allows their classification as actively deployed type III effectors. Our data also show that HopAO1 and HopAO2 possess phosphatase activity, a hallmark of the members of this family. Both of them exert an inhibitory effect on early plant defense responses, such as ROS production and callose deposition, and are able to suppress ETI responses induced by the effectorless polymutant of P. syringae pv. tomato DC3000 (DC3000D28E in Nicotiana. Moreover, we demonstrate that a ΔhopAO1 mutant of P. savastanoi NCPBB 3335 exhibits a reduced fitness and virulence in olive plants, which supports the relevance of this effector during the interaction of this strain with its host plants. This work contributes to the field with the first report regarding functional analysis of HopAO homologs encoded by P. syringae or P. savastanoi strains isolated from woody hosts.

    Research carried out during the past two-decades extended the understanding of actions of vitamin D, from regulating calcium and phosphate absorption and bone metabolism to many pleiotropic actions in organs and tissues in the body. Most observational and ecological studies report association of higher serum 25-hydroxyvitamin D [25(OH)D] concentrations with improved outcomes for several chronic, communicable and non-communicable diseases. Consequently, numerous agencies and scientific organizations have developed recommendations for vitamin D supplementation and guidance on optimal serum 25(OH)D concentrations. The bone-centric guidelines recommend a target 25(OH)D concentration of 20ng/mL (50nmol/L), and age-dependent daily vitamin D doses of 400-800IU. The guidelines focused on pleiotropic effects of vitamin D recommend a target 25(OH)D concentration of 30ng/mL (75nmol/L), and age-, body weight-, disease-status, and ethnicity dependent vitamin D doses ranging between 400 and 2000IU/day. The wise and balanced choice of the recommendations to follow depends on one's individual health outcome concerns, age, body weight, latitude of residence, dietary and cultural habits, making the regional or nationwide guidelines more applicable in clinical practice. While natural sources of vitamin D can raise 25(OH)D concentrations, relative to dietary preferences and latitude of residence, in the context of general population, these sources are regarded ineffective to maintain the year-round 25(OH)D concentrations in the range of 30-50ng/mL (75-125nmol/L). Vitamin D self-administration related adverse effects, such as hypercalcemia and hypercalciuria are rare, and usually result from taking extremely high doses of vitamin D for a prolonged time.

  20. Mineral supplementation for grazing ruminants

    McDowell, L.R.; Conrad, J.H.; Ellis, G.L.

    1986-01-01

    Grazing ruminants to which concentrate feeds cannot be economically fed must rely on self-feeding of mineral supplements. A number of factors affect mineral consumption of free-choice mixtures. Livestock exhibit little nutritional wisdom and will select palatable mixtures in preference to mixtures designed to meet their requirements. Palatability and appetite stimulators are often used to achieve a more uniform herd-wide consumption. It is best to formulate free-choice mixtures on the basis of analyses or other available data. However, when no information on mineral status is known, a free-choice complete mineral supplement is warranted. A 'complete' mineral mixture usually includes salt, a low fluoride P source, Ca, Co, Cu, I, Mn and Zn. Selenium, Mg, K, S, Fe or additional elements can be incorporated into a mineral supplement as new information suggests a need. The detriment to ruminant production caused by providing Ca, Se and Cu in excess can be greater than any benefit derived by providing a mineral supplement. In regions where high forage Mo predominates, three to five times the Cu content in mineral mixtures is needed to counteract Mo toxicity. Supplemental minerals are most critical during the wet season, when cattle are gaining weight rapidly and energy and protein supplies are adequate. Economic return on mineral supplementation is high.

  1. Cardiovascular Effects of Calcium Supplements

    Directory of Open Access Journals (Sweden)

    Ian R. Reid

    2013-07-01

    Full Text Available Calcium supplements reduce bone turnover and slow the rate of bone loss. However, few studies have demonstrated reduced fracture incidence with calcium supplements, and meta-analyses show only a 10% decrease in fractures, which is of borderline statistical and clinical significance. Trials in normal older women and in patients with renal impairment suggest that calcium supplements increase the risk of cardiovascular disease. To further assess their safety, we recently conducted a meta-analysis of trials of calcium supplements, and found a 27%–31% increase in risk of myocardial infarction, and a 12%–20% increase in risk of stroke. These findings are robust because they are based on pre-specified analyses of randomized, placebo-controlled trials and are consistent across the trials. Co-administration of vitamin D with calcium does not lessen these adverse effects. The increased cardiovascular risk with calcium supplements is consistent with epidemiological data relating higher circulating calcium concentrations to cardiovascular disease in normal populations. There are several possible pathophysiological mechanisms for these effects, including effects on vascular calcification, vascular cells, blood coagulation and calcium-sensing receptors. Thus, the non-skeletal risks of calcium supplements appear to outweigh any skeletal benefits, and are they appear to be unnecessary for the efficacy of other osteoporosis treatments.

    The main goal of Green Flash is to design and build a prototype for a Real-Time Controller (RTC) targeting the European Extremely Large Telescope (E-ELT) Adaptive Optics (AO) instrumentation. The E-ELT is a 39m diameter telescope to see first light in the early 2020s. To build this critical component of the telescope operations, the astronomical community is facing technical challenges, emerging from the combination of high data transfer bandwidth, low latency and high throughput requirements, similar to the identified critical barriers on the road to Exascale. With Green Flash, we will propose technical solutions, assess these enabling technologies through prototyping and assemble a full scale demonstrator to be validated with a simulator and tested on sky. With this R&D program we aim at feeding the E-ELT AO systems preliminary design studies, led by the selected first-light instruments consortia, with technological validations supporting the designs of their RTC modules. Our strategy is based on a strong interaction between academic and industrial partners. Components specifications and system requirements are derived from the AO application. Industrial partners lead the development of enabling technologies aiming at innovative tailored solutions with potential wide application range. The academic partners provide the missing links in the ecosystem, targeting their application with mainstream solutions. This increases both the value and market opportunities of the developed products. A prototype harboring all the features is used to assess the performance. It also provides the proof of concept for a resilient modular solution to equip a large scale European scientific facility, while containing the development cost by providing opportunities for return on investment.

    Many crosscutting concerns in business processes need to be addressed already at the business process modeling level such as compliance, auditing, billing, and separation of duties. However, existing business process modeling languages including OMG's Business Process Modeling Notation (BPMN) lack appropriate means for expressing such concerns in a modular way. In this paper, we motivate the need for aspect-oriented concepts in business process modeling languages and propose an aspect-oriented extension to BPMN called AO4BPMN. We also present a graphical editor supporting that extension.

    Vitamin C supplementation may help reduce the risk of pregnancy complications such as pre-eclampsia, intrauterine growth restriction and maternal anaemia. There is a need to evaluate the efficacy and safety of vitamin C supplementation in pregnancy. To evaluate the effects of vitamin C supplementation, alone or in combination with other separate supplements on pregnancy outcomes, adverse events, side effects and use of health resources. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 March 2015) and reference lists of retrieved studies. All randomised or quasi-randomised controlled trials evaluating vitamin C supplementation in pregnant women. Interventions using a multivitamin supplement containing vitamin C or where the primary supplement was iron were excluded. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Twenty-nine trials involving 24,300 women are included in this review. Overall, 11 trials were judged to be of low risk of bias, eight were high risk of bias and for 10 trials it was unclear. No clear differences were seen between women supplemented with vitamin C alone or in combination with other supplements compared with placebo or no control for the risk of stillbirth (risk ratio (RR) 1.15, 95% confidence intervals (CI) 0.89 to 1.49; 20,038 participants; 11 studies; I² = 0%; moderate quality evidence), neonatal death (RR 0.79, 95% CI 0.58 to 1.08; 19,575 participants; 11 studies; I² = 0%), perinatal death (average RR 1.07, 95% CI 0.77 to 1.49; 17,105 participants; seven studies; I² = 35%), birthweight (mean difference (MD) 26.88 g, 95% CI -18.81 to 72.58; 17,326 participants; 13 studies; I² = 69%), intrauterine growth restriction (RR 0.98, 95% CI 0.91 to 1.06; 20,361 participants; 12 studies; I² = 15%; high quality evidence), preterm birth (average RR 0.99, 95% CI 0.90 to 1.10; 22,250 participants; 16 studies; I² = 49%; high quality evidence

This study assessed the effects of boron supplementation on broiler performance. Diets were based on maize and soybean meal, using boric acid P.A. as boron source. Six supplementation levels (0, 30, 60, 90, 120 and 150 ppm were evaluated using 1,440 one-day old males housed at a density of 30 chickens in each of 48 experimental plots of 3m². A completely randomized block design was used with 8 replicates. Feed intake, weight gain and feed conversion were assessed in the periods from 1 to 7 days, 1 to 21 days and 1 to 42 days of age, and viability was evaluated for the total 42-day rearing period. No performance variable was affected by boron supplementation (p>0.05 in the period from 1 to 7 days. The regression analysis indicated an ideal level of 37.4 ppm of boron for weight gain from 1 to 21 days (p0.05, although feed intake was reduced linearly with increased boron levels (p0.05. Ash and calcium percentages in the tibias of broilers and viability in the total rearing period were not affected by boron supplementation (p>0.05.

    With the increasing use of unregulated dietary supplements, athletes are at continued risk from adverse medical events and inadvertent doping. A review of Clinical Key, MEDLINE, and PubMed databases from 2012 to 2017 was performed using search terms, including dietary supplement, contamination, doping in athletes, inadvertent doping, and prohibited substances. The references of pertinent articles were reviewed for other relevant sources. Clinical review. Level 3. Poor manufacturing processes and intentional contamination with many banned substances continue to occur in dietary supplements sold in the United States. Certain sectors, such as weight loss and muscle-building supplements, pose a greater threat because they are more likely to be contaminated. Athletes will continue to be at risk for adverse events and failed doping tests due to contaminated dietary supplements until legislation changes how they are regulated. In the interim, there are several steps that can be taken to mitigate this risk, including improved education of medical staff and athletes and use of third party-certified products.

    Wilborn, Colin

    Over the last decade research involving nutritional supplementation and sport performance has increased substantially. Strength and power athletes have specific needs to optimize their performance. Nutritional supplementation cannot be viewed as a replacement for a balanced diet but as an important addition to it. However, diet and supplementation are not mutually exclusive, nor does one depend on the other. Strength and power athletes have four general areas of supplementation needs. First, strength athletes need supplements that have a direct effect on performance. The second group of supplements includes those that promote recovery. The third group comprises the supplements that enhance immune function. The last group of supplements includes those that provide energy or have a direct effect on the workout. This chapter reviews the key supplements needed to optimize the performance and training of the strength athlete.

  4. Polarization burst in the BL Lac object AO 0235 + 164

    Energy Technology Data Exchange (ETDEWEB)

    Impey, C D; Brand, P W.J.L. [Edinburgh Univ. (UK). Dept. of Astronomy; Tapia, S [Steward Observatory, Tucson, AZ (USA)

    1982-01-01

    Simultaneous infrared and optical polarimetry and photometry have been obtained for AO 0235 + 164 covering a five night period. The object underwent a polarization burst during which the 2.2 ..mu..m polarization rose from 17.5 to 28.7 per cent and fell again to 14.9 per cent. At its peak the degree of optical polarization was 43.9 per cent, the highest linear polarization observed in a BL Lac object. The data show the degree of polarization to increase towards shorter wavelengths, and the effect is inconsistent with either dilution by a galactic component or simple one-component synchrotron models. The large changes in polarization are not accompanied by large changes in flux, a result which is difficult to explain using conventional models of these objects. Other implications of the luminosity, polarization and variability are discussed.

As repercussões deste fato atingem o mundo inteiro, desde a própria Rússia, o centro do sistema, até as longínquas periferias do socialismo chamado ''real", em Cuba e Nicarágua, e também, de modo paradoxal, a África do Sul, onde o desmantelamento do socialismo soviético diminuiu o medo dos afrikaanders brancos diante do movimento antiapartheid, suspeito de ser um posto avançado do comunismo mundial.

    Objective Describe the content and frequency of provider-patient dietary supplement discussions during primary care office visits. Methods Inductive content analysis of 1477 transcribed audio-recorded office visits to 102 primary care providers was combined with patient and provider surveys. Encounters were collected in Los Angeles, California (2009–2010), geographically-diverse practice settings across the United States (2004–2005), and Sacramento, CA (1998–1999). Results Providers discussed 738 dietary supplements during encounters with 357 patients (24.2% of all encounters in the data). They mentioned: 1) reason for taking the supplement for 46.5% of dietary supplements; 2) how to take the supplement for 28.2%; 3) potential risks for 17.3%; 4) supplement effectiveness for 16.7%; and 5) supplement cost or affordability for 4.2%. Of these five topics, a mean of 1.13 (SD=1.2) topics were discussed for each supplement. More topics were reviewed for non-vitamin non-mineral supplements (mean 1.47 (SD=1.2)) than for vitamin/mineral supplements (mean 0.99 (SD=1.1); psupplements are occurring, it is clear that more discussion might be needed to inform patient decisions about supplement use. Practice Implication Physicians could more frequently address topics that may influence patient dietary supplement use, such as the risks, effectiveness, and costs of supplements. PMID:23466249

  14. Muscle Mass and Weight Gain Nutritional Supplements

    Science.gov (United States)

    Campbell, Bill

    There are numerous sports supplements available that claim to increase lean body mass. However, for these sports supplements to exert any favorable changes in lean body mass, they must influence those factors regulating skeletal muscle hypertrophy (i.e., satellite cell activity, gene transcription, protein translation). If a given sports supplement does favorably influence one of these regulatory factors, the result is a positive net protein balance (in which protein synthesis exceeds protein breakdown). Sports supplement categories aimed at eliciting a positive net protein balance include anabolic hormone enhancers, nutrient timing pre- and postexercise workout supplements, anticatabolic supplements, and nitric oxide boosters. Of all the sports supplements available, only a few have been subject to multiple clinical trials with repeated favorable outcomes relative to increasing lean body mass. This chapter focuses on these supplements and others that have a sound theoretical rationale in relation to increasing lean body mass.

    2018-01-06

    Over 70% of Americans take some form of dietary supplement every day, and the supplement industry is currently big business, with a gross of over $28 billion. However, unlike either foods or drugs, supplements do not need to be registered or approved by the US Food and Drug Administration (FDA) prior to production or sales. Under the Dietary Supplement Health and Education Act of 1994, the FDA is restricted to adverse report monitoring postmarketing. Despite widespread consumption, there is limited evidence of health benefits related to nutraceutical or supplement use in well-nourished adults. In contrast, a small number of these products have the potential to produce significant toxicity. In addition, patients often do not disclose supplement use to their physicians. Therefore, the risk of adverse drug-supplement interactions is significant. An overview of the major supplement and nutraceutical classes is presented here, together with known toxic effects and the potential for drug interactions.

    Full Text Available OBJETIVO: Analisar as decisões do sistema jurídico sobre acesso da população a medicamentos no Sistema Único de Saúde por via judicial quanto a critérios de decisão e eventuais pressões políticas e econômicas. MÉTODOS: Estudo documental descritivo e retrospectivo de abordagem qualitativa e quantitativa. A coleta de dados foi realizada na Superintendência Estadual de Assistência Farmacêutica de Pernambuco, utilizando-se como fontes de dados 105 ações judiciais e relatórios administrativos de janeiro a junho de 2009. Verificaram-se os medicamentos com pedido ou carta patente no banco de dados do Instituto Nacional de Propriedade Industrial para identificar a frequência das patentes nas ações judiciais. Os dados obtidos foram classificados conforme o Sistema Anatômico Terapêutico Químico. Para análise das decisões judiciais, foi utilizada a teoria dos sistemas sociais autopoiéticos. RESULTADOS: As ações judiciais somaram 134 medicamentos com valor estimado de R$ 4,5 milhões para atender aos tratamentos solicitados; 70,9% dos medicamentos estavam com carta patente ou pedido e se concentraram em três classes terapêuticas: antineoplásicos e moduladores imunológicos, aparelho digestório e metabolismo, órgãos dos sentidos. Foram identificadas seis ideias centrais com os critérios de decisão dos magistrados (Constituição Federal e prescrição médica e as pressões entre os sistemas do direito, da economia e da política quanto ao acesso a medicamentos. CONCLUSÕES: A análise das decisões judiciais fundamentadas na teoria dos sistemas sociais autopoiéticos permitiu identificar as estimulações mútuas (dependências entre o sistema do direito e demais sistemas sociais em relação à questão do acesso dos cidadãos aos medicamentos. Essas dependências foram representadas pela Constituição Federal e pela propriedade intelectual. A Constituição Federal e a prescrição médica foram identificadas como

Os dados do International Obesity Task Force (2000 mostraram que, nos últimos anos, a prevalência de obesidade tem aumentado significativamente em várias regiões do mundo, sendo responsável, em grande parte, pelo aumento da mortalidade e morbilidade com implicações significativas no indivíduo, na família e na comunidade (Dietz et al, 1999; Cole et al, 2000. O impacto no indivíduo pode ser quantificado pela influência na qualidade de vida, no recurso aos serviços de saúde, no absentismo escolar, na limitação nas actividades de vida diária, nomeadamente na prática de desporto e alterações nas relações interpessoais, marginalização, depressão e isolamento. Ao nível da família, as repercussões podem traduzir-se no absentismo profissional, nas alterações dos estilos de vida e na necessidade de acompanhamento dos familiares.  O aumento da prevalência de obesidade e consequente aumento do risco de desenvolvimento de doenças crónicas na idade adulta, que lhe está associado, deve ser rigorosamente monitorizado (Cole et al, 2000; WHO, 1995. Essa monitorização DEVE permitir avaliar a evolução do problema, proceder a comparações entre várias regiões e ou países e determinar a eficácia das intervenções introduzidas para minimizar o problema. Para que tal aconteça, torna-se necessário uniformizar os conceitos de excesso de peso e obesidade para que possam ser amplamente utilizados.

    Robo-AO is the first and only fully automated adaptive optics laser guide star AO instrument. It was developed as an instrument for 1-3m robotic telescopes, in order to take advantage of their availability to pursue large survey programs and target of opportunity observations that aren't possible with other AO systems. Robo-AO is currently the most efficient AO system in existence, and it can achieve an observation rate of 20+ science targets per hour. In more than three years of operations at Palomar Observatory, it has been quite successful, producing technology that is being adapted by other AO systems and robotic telescope projects, as well as several high impact scientific publications. Now, Robo-AO has been selected to take over operation of the Kitt Peak National Observatory 2.1m telescope. This will give Robo-AO KP the opportunity to pursue multiple science programs consisting of several thousand targets each during the three years it will be on the telescope. One-sixth of the observing time will be allocated to the US community through the NOAO TAC process. This presentation will discuss the process adapting Robo-AO to the KPNO 2.1m telescope, the plans for integration and initial operations, and the science operations and programs to be pursued.

Essa avaliação é feita no interior da teoria do valor-trabalho e da crítica da economia política. Para tanto, interroga, primeiro, o verdadeiro impacto da informatização na natureza capitalista dos processos produtivos atualmente em andamento, principalmente nos países centrais. Compara, depois, as principais características da indústria taylorista com as características marcantes da indústria pós-taylorista. Ao final, conclui que uma transformação importante do sistema capitalista está em curso: a grande indústria, tal como foi caracterizada por Marx em O Capital, não predomina mais nos países do centro do sistema, pois o que aí prevalece agora é a pós-grande indústria.

    Full Text Available O objetivo deste artigo é examinar o processo de constituição do anticapitalismo por meio da análise da Rerum Novarum, a primeira encíclica social. Comparando esta com as encíclicas anteriores do século XIX, pudemos estabelecer o que ela trouxe de novidade no que diz respeito ao combate que a Igreja travava contra o socialismo. Com essa comparação, foi possível caracterizar a postura anticapitalista, confrontando a nossa maneira de concebê-la com as demais. Para o exame da Rerum Novarum foi igualmente importante analisar alguns estudos referentes a ela, tanto os que apareceram logo após a sua publicação como os que foram realizados em décadas mais recentes. Como conclusão, definimos o anticapitalismo como uma atitude que somente poderia ter surgido em condições sociais e políticas bastante particulares e que apenas apareceram em fins do século XIX.

    Miscarriage is a common complication of pregnancy that can be caused by a wide range of factors. Poor dietary intake of vitamins has been associated with an increased risk of miscarriage, therefore supplementing women with vitamins either prior to or in early pregnancy may help prevent miscarriage. The objectives of this review were to determine the effectiveness and safety of any vitamin supplementation, on the risk of spontaneous miscarriage. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (6 November 2015) and reference lists of retrieved studies. All randomised and quasi-randomised trials comparing supplementation during pregnancy with one or more vitamins with either placebo, other vitamins, no vitamins or other interventions. We have included supplementation that started prior to conception, periconceptionally or in early pregnancy (less than 20 weeks' gestation). Three review authors independently assessed trials for inclusion, extracted data and assessed trial quality. We assessed the quality of the evidence using the GRADE approach. The quality of evidence is included for numerical results of outcomes included in the 'Summary of findings' tables. We included a total of 40 trials (involving 276,820 women and 278,413 pregnancies) assessing supplementation with any vitamin(s) starting prior to 20 weeks' gestation and reporting at least one primary outcome that was eligible for the review. Eight trials were cluster-randomised and contributed data for 217,726 women and 219,267 pregnancies in total.Approximately half of the included trials were assessed to have a low risk of bias for both random sequence generation and adequate concealment of participants to treatment and control groups. Vitamin C supplementation There was no difference in the risk of total fetal loss (risk ratio (RR) 1.14, 95% confidence interval (CI) 0.92 to 1.40, seven trials, 18,949 women; high-quality evidence); early or late miscarriage (RR 0.90, 95% CI 0.65 to 1

De origem eslovena, e quase eleito presidente de seu país, Slavoj Žižek é autor de diversos livros - dentre os quais os instigantes ensaios “Hegel, o mais sublime dos histéricos” e “Eles não sabem o que dizem” -, a maioria publicada em por volta de trinta idiomas. É ele reconhecido como sendo um profundo conhecedor de Hegel e Karl Marx; apaixonado leitor de Sigmund Freud e de Jacques Lacan; crítico contundente das ideologias totalitárias, espírito cultivado por sua filia às múltiplas artes – sendo, inclusive, especialista na cinematografia de Alfred Hitchcock. Os traços de sua erudição e sensibilidade para com as artes, se refletem e particularizam, também, o seu estilo de escrever, o qual se encontra muito bem representado no modo como urdiu esse seu novo livro. “Como ler Lacan” nos ensina a adotar um método especial para orientar em uma tal empreitada. Žižek advoga que, para lermos Lacan, devemos aplicar o mesmo método empregado pela psicanálise para ler e interpretar o texto que resulta do trabalho inconsciente. Mas há uma condição para esse emprego: abandonar o vício de querer entender, pois, assim como o inconsciente, Lacan não deve ser compreendido e sim lido, pois, conforme ele mesmo já nos advertira, o pior destino a que podemos ser conduzidos é o destino que nos leva à compreensão. Só assim será fácil ler Lacan, mais do que, amiúde, se imagina. Muitas introduções ao seu ensino foram publicadas, algumas delas marcadas por rigor conceitual, outras resultaram em versões grosseiras de sua letra. Sem desmerecer as boas introduções a Lacan

    Análises de participação de mercado ("market share" são comuns em estudos na área de "marketing", envolvendo produtos e respectivas marcas, de um lado, o perfil da demanda de outro, e o posicionamento das empresas produtoras que competem nesse mercado, num terceiro bloco. No setor de transportes a literatura registra aplicações em ligações aéreas e em serviços intermunicipais de ônibus. Os modelos de participação de mercado se aplicam normalmente a situações em que os operadores oferecem serviços de transportes similares num determinado mercado, com a competição sendo feita não com base em atributos modais intrínsecos, mas sim apoiada em características diferenciadoras intra-modais mais tênues, tais como conforto, atendimento, promoções tarifárias, "marketing" e propaganda, etc. Neste artigo é feita uma introdução aos modelos de "market share" em transportes, com a apresentação de um exemplo de aplicação ao transporte intermunicipal de passageiros em ônibus, sendo discutidos também aspectos ligados a calibração e tais modelos.

    ABSTRACT

    Market share analysis is common in marketing studies involving products and respective brands, on one hand, the demand profile on the other hand, and the competiting industries on a third set. In the transport sector the literature registers a number of applications to air transport problems and to intercity bus services. Market share models are normally applied to situations in which operators offer, in a specific market, transport services that are similar in nature, with competition based not on intrinsic modal attributes, but rather on more tenous intra-mode differentiating characteristics, such as comfort, attendance, tariff promotions, marketing and advertising efforts, etc (sub-modal configurations.

    2015-03-01

    Evidence for the benefit of nutrition in Alzheimer's disease continues to accumulate. Many studies with individual vitamins or supplements show marginal, if any, benefit. However, new findings with combinatorial formulations demonstrate improvement in cognitive performance and behavioral difficulties that accompany Alzheimer's disease. Herein, we review some of the most recent clinical advances and summarize supportive preclinical studies. We present novel positive effects on Alzheimer's disease derived from diet, trace elements, vitamins and supplements. We discuss the inherent difficulty in conducting nutritional studies because of the variance in participants' nutritional history, versus pharmacological interventions in which participants are naive to the intervention. We examine the evidence that epigenetics play a role in Alzheimer's disease and how nutritional intervention can modify the key epigenetic events to maintain or improve cognitive performance. Overall consideration of the most recent collective evidence suggests that the optimal approach for Alzheimer's disease would seem to combine early, multicomponent nutritional approaches (a Mediterranean-style diet, multivitamins and key combinatorial supplements), along with lifestyle modifications such as social activity and mental and physical exercise, with ultimate addition of pharmacological agents when warranted.

  1. Why US children use dietary supplements

    Bailey, Regan L.; Gahche, Jaime J.; Thomas, Paul R.; Dwyer, Johanna T.

    2013-01-01

    Background: Dietary supplements are used by one-third of children. We examined motivations for supplement use in children, the types of products used by motivations, and the role of physicians and health care practitioners in guiding choices about supplements. Methods: We examined motivations for dietary supplement use reported for children (from birth to 19 y of age; n = 8,245) using the National Health and Nutrition Examination Survey 2007–2010. Results: Dietary supplements were used by 31% of children; many different reasons were given as follows: to “improve overall health” (41%), to “maintain health” (37%), for “supplementing the diet” (23%), to “prevent health problems” (20%), and to “boost immunity” (14%). Most children (~90%) who use dietary supplements use a multivitamin–mineral or multivitamin product. Supplement users tend to be non-Hispanic white, have higher family incomes, report more physical activity, and have health insurance. Only a small group of supplements used by children (15%) were based on the recommendation of a physician or other health care provider. Conclusion: Most supplements used by children are not under the recommendation of a health care provider. The most common reasons for use of supplements in children are for health promotion, yet little scientific data support this notion in nutrient-replete children. PMID:24002333

    There is currently many over the counter products on the market that exert nutritional or physiological effects on the human body. The differences between dietary supplements and non-prescription drugs are however poorly understood by the average consumer and may thus affect their expectations as to the desired effect produced on the body. To evaluate patients' knowledge and attitudes towards dietary supplements as compared to non-prescription drugs. Subjects were 335 patients of the Mazowiecki Voivodeship Hospital in Warsaw, Poland. The data were collected from a face-to-face interview using a single and multiple choice questionnaire with 10 questions on dietary supplements. Statistical analysis used the Chi-square (χ2) test. The majority of respondents were found to be familiar with the term 'dietary supplements', but had difficulties in classifying these products into appropriate categories. Over 55% do not consider dietary supplements to be foodstuffs and more than 40% considered such products to be drugs. Most respondents thought that the main purpose of taking dietary supplements is to improve nutrition, but over one third expected them to also treat disease. Over 70% declared taking notice to which category the non-prescription products they bought belongs to ie. whether non-prescription drugs (medicinal products) or dietary supplements. Many patients mistakenly believe that dietary supplements are drugs and can be used to treat disease and health disorders. dietary supplements, opinion on dietary supplements, nutrition, dietary supplement vs. medicinal product.

Foram tabuladas/analisadas 3.569 cláusulas de acordos coletivos, e realizadas 26 entrevistas com dirigentes sindicais e empresariais em três Estados (RJ, SP e MG. Os resultados indicam que as mudanças organizacionais foram incomparavelmente mais negociadas no setor metalúrgico do ABC. A flexibilização da jornada foi trocada pela redução (da jornada sem redução de salário nos setores metalúrgicos paulistas, mas não em Minas Gerais. No setor bancário, houve poucos resultados nas negociações sobre jornada. As negociações em torno da remuneração variável vinculada às metas das empresas aconteceram nos setores metalúrgicos, e não nos setores de serviços. As entrevistas apontam para um sindicalismo mais propositivo, no sentido de uma intervenção negociada, predisposição que não é correspondida pelos empresários, grosso modo. O Estado, que poderia utilizar seu poder regulador para induzir os empresários a negociarem nessa direção não tem produzido resultados satisfatórios. Conclui-se que não há maturidade empresarial no Brasil que permita ao Estado ausentar-se das relações de trabalho.

    Dietary supplement use is endemic in young athletes; however, it is unclear if their choices are congruent with their motivation for supplementation and the established benefits of the dietary supplements. The aim of this study was to evaluate the relationships between dietary supplement use and self-reported rationale in young athletes. Canadian athletes (n = 567; 11-25 years; 76% club or provincial level, 24% national or higher) completed a questionnaire designed to assess supplementation patterns and motivation for supplementation. Chi square tests examined associations between dietary supplements and self-reported rationale for use. Vitamin and mineral supplements, including vitamin-enriched water, were associated with several health- and performance- related reasons (p performance reasons, as were performance foods (protein powder, sport bars, sport gels, etc.). Plant extracts and fatty acids were primarily associated with health reasons, particularly immune support (p performance rationales and supplementation for common ergogenic aids, however, less so for vitamin and mineral supplements, vitamin-enriched water, and plant extracts. Incongruences were found between fatty acids, protein supplements, vitamin and mineral supplements, vitamin-enriched water, and plant extracts and health motivators for supplementation. Educational interventions are essential to ensure young athletes are using dietary supplements safely and effectively.

  11. Athletes and Supplements: Prevalence and Perspectives.

    Garthe, Ina; Maughan, Ronald J

    2018-03-01

    In elite sport, where opponents are evenly matched, small factors can determine the outcome of sporting contests. Not all athletes know the value of making wise nutrition choices, but anything that might give a competitive edge, including dietary supplements, can seem attractive. Between 40% and 100% of athletes typically use supplements, depending on the type of sport, level of competition, and the definition of supplements. However, unless the athlete has a nutrient deficiency, supplementation may not improve performance and may have a detrimental effect on both performance and health. Dietary supplements are classified as a subcategory of food, so manufacturers are not required to provide evidence of product safety and efficacy, nor obtain approval from regulatory bodies before marketing supplements. This creates the potential for health risks, and serious adverse effects have been reported from the use of some dietary supplements. Athletes who compete in sports under an anti-doping code must also realize that supplement use exposes them to a risk of ingesting banned substances or precursors of prohibited substances. Government systems of regulations do not include specific laboratory testing for banned substances according to the WADA list, so a separate regulatory framework to evaluate supplements for their risk of provoking a failed doping test is needed. In the high-performance culture typical of elite sport, athletes may use supplements regardless of possible risks. A discussion around medical, physiological, cultural, and ethical questions may be warranted to ensure that the athlete has the information needed to make an informed choice.

Vemos o artista-teórico completo, profundo conhecedor da história da arte eletrônica. O livro Luz & letra: ensaios de arte, literatura e comunicação, sua obra de referência, é apresentado em essência, situando-se sua importância. É uma das poucas obras no Brasil a discutir, pela ótica de quem fez parte, eventos ligados ao advento da arte tecnológica nos anos 1980.In our quest to understand scientific advances, we seek to understand ourselves. Employing Carl Sagan's insight as a departure point, we see that art is one of the paths for humanization and that the links between science (technology and art are increasingly narrow. One of the artists who best works within the realm known as “art and technology” is Eduardo Kac. This essay explores Kac's early artworks, starting with “holopoems” and arriving at “telepresence art”, and especially his texts. We see a complete artist-theorist, with an unrivaled knowledge of electronic art and literature, in part because his theorizing emerges from having actively participated in the creation of the events he refers to. Of special interest is Kac's book Light & letter: essays in art, literature, and communication, which collects his writings of the 1980s. This is a fundamental work and mandatory reference for the study of the experimental art and literature of the period.

    Ling Ao Nuclear Power Station (LANP) is first one built up by self-reliance in China with power capacity 990x2 MWe. The results of quality control, schedule control and cost control are satisfactory. The commercial operation days of Unit 1 and Unit 2 were 28th May 2002 and 8th Jan. 2003 respectively, which were 48 days and 66 days in advance of the project schedule. This paper presents the practices of self-reliance schedule control system in LANP. The paper includes 10 sections: schedule control system; targets of schedule control; schedule control at early stage of project; construction schedule; scheduling practice; Point curves; schedule control of design and procurement; a good practice of construction schedule control on site; commissioning and startup schedule; schedule control culture. Three figures are attached. The main contents of the self-reliance schedule control system are as follows: to draw up reasonable schedules and targets; to setup management mechanism and procedures; to organize powerful project management team; to establish close monitoring system; to provide timely progress reports and statistics information. Five kinds of schedule control targets are introduced, i.e. bar-chart schedule; milesones; Point curves; interface management; hydraulic test schedule of auxiliary piping loops; EMR/EMC/EESR issuance schedules. Six levels of bar-chart schedules were adopted in LANP, but the bar-chart schedules were not satisfactory for complicated erection condition on site, even using six levels of schedules. So a kind of Point curves was developed and their advantages are explained. Scheduling method of three elements: activity, duration, logic, which was adopted in LANP, is introduced. The duration of each piping activities in LANP level 2 project schedule was calculated based on the relevant working Point quantities. The analysis and adjustment of Point curves are illustrated, i.e. balance of monthly quantities; possible production in the peakload

Objetivou-se analisar possíveis relações entre percepção de qualidade de vida e a vulnerabilidade ao estresse no trabalho em enfermeiros, técnicos e auxiliares de enfermagem que atuam na UTI e no setor de emergência de um hospital público. Utilizou-se o instrumento de qualidade de vida da Organização Mundial da Saúde, WHOQOL-Bref e a Escala de Vulnerabilidade ao Estresse no Trabalho. Encontrou-se, em relação ao setor de trabalho, diferença significativa apenas para Qualidade de vida total. Portanto pode-se afirmar que os profissionais que atuam na UTI possuem maior percepção de qualidade de vida quando comparados aos do SUS. Na correlação entre os dois instrumentos, o domínio meio ambiente do WHOQOL-Bref correlacionou-se negativa e significativamente com todos os fatores da EVENT, indicando que a percepção da pessoa em relação aos diversos aspectos do meio em que vive tem relação com a vulnerabilidade ao estresse.

    Contemporary elite soccer features increased physical demands during match-play, as well as a larger number of matches per season. Now more than ever, aspects related to performance optimization are highly regarded by both players and soccer coaches. Here, nutrition takes a special role as most elite teams try to provide an adequate diet to guarantee maximum performance while ensuring a faster recovery from matches and training exertions. It is currently known that manipulation and periodization of macronutrients, as well as sound hydration practices, have the potential to interfere with training adaptation and recovery. A careful monitoring of micronutrient status is also relevant to prevent undue fatigue and immune impairment secondary to a deficiency status. Furthermore, the sensible use of evidence-based dietary supplements may also play a role in soccer performance optimization. In this sense, several nutritional recommendations have been issued. This detailed and comprehensive review addresses the most relevant and up-to-date nutritional recommendations for elite soccer players, covering from macro and micronutrients to hydration and selected supplements in different contexts (daily requirements, pre, peri and post training/match and competition).

    1966-03-01

    Full Text Available Resumindo as principais contribuições que resultaram na conceituação atual da hipsarritmia, destacam os autores a noção de que não constitui ela uma entidade clínica determinada, mas uma sindrome eletroclínica especial, própria da primeira infância, e cujo diagnóstico só pode ser firmado à luz do traçado eletrencefalográfico característico. Analisam a variedade de fatôres etiológicos à maneira do que ocorre com as encefalopatias infantis em geral, chamando a atenção para a importância do fator etário, das condições traumáticas e do problema da anóxia cerebral neonatorum. Necessária ênfase é conferida ao fenômeno da maturação encefálica que explica, segundo o consenso dos autores modernos, as características peculiares da síndrome. A hipsarritmia pode instalar-se em indivíduo previamente são ou em encefalopata, tendo evolução variável, pois tanto pode evolver favoràvelmente, o que é mais raro, como modificar-se, seja no sentido da epilepsia focal ou outra forma de epilepsia, o que é mais comum, ou, então, permanecer inalterada. Essa evolução - a história natural da hipsarritmia - é apreciada especialmente sob o aspecto eletrencefalográfico, o qual pode, ou não, ser acompanhado de correspondente evolução clínica. A sintomatologia é variável, sendo de notar a grande dominância das crises de espasmos em flexão. Sendo pobre o subsídio anátomo-patológico da condição, os autores, a êsse propósito, apenas acrescentam os dados referentes à necropsia de um dos seus casos, com achados inespecíficos. O prognóstico, na maioria das vêzes mau, pode variar, especialmente após o uso do ACTH. O tratamento é difícil, freqüentemente desapontador. As melhores respostas são obtidas com o ACTH e, algumas vêzes, com os antibióticos e medicação sintomática, porém, quase sempre reaparece a sintomatologia, se suprimida a medicação que, por outro lado, nem sempre pode ser continuada.

Assim, o presente estudo aborda o empreendedorismo na piscicultura, tomando como base três casos analisados: uma propriedade com rizipiscicultura, uma com piscicultura de ciclo completo inclusive com frigorífico, e outra onde a piscicultura desenvolve-se através de um pesque-pague, com vistas a proporcionar o turismo rural. Para fins de pesquisa, entrevistaram-se os proprietários de cada estabelecimento na busca dos dados necessários para a construção de uma abordagem consistente da temática proposta, ou seja, identificar a presença do empreendedorismo e suas características particulares em cada propriedade analisada. Verificou-se que determinadas características empreendedoras são comuns aos três casos analisados: habilidade para identificar oportunidades; busca de conhecimento de sua área de atuação; senso de organização; disposição para tomar decisões; capacidade de liderança; talento para empreender; otimismo e tino empresarial; ser estrategista, além do dinamismo. Portanto, foi possível observar que o perfil empreendedor dos proprietários de cada negócio tornou possível a transformação de idéias e problemas em oportunidades reais de negócio.Abstract The business opening is indicated as one of the prosperity causes of a country, state, region or local. It’s in this context that the entrepreneurship has received attention along the last years as new business promoter.

    Full Text Available ABSTRACT Objective: To investigate the prevalence and establish the profile of the consumption of dietary supplements among Brazilian athletes. Methods: A total of 182 athletes of both genders from 20 different sports participated in this study. The athletes answered a questionnaire containing sociodemographic and sports-related questions and were interviewed about the consumption of dietary supplements. Results: Forty seven percent of athletes reported having consumed at least one type of dietary supplement and 38% said they use more than three different types of supplements concurrently. Whey protein was the most commonly consumed supplement, and the most frequently mentioned reason for its consumption was performance improvement. The main source of information was coaches, and individual sport athletes were the greatest consumers and the most likely to seek dietary supplement. Conclusion: Approximately half of the participants used dietary supplements, which on most occasions were recommended by coaches. The consumption profile also revealed multiple supplementation practice and showed that nutrition education is essential for this specific population.

The aim of this study was to estimate the prevalence and determinants of using supplements among body builder athletes. METHODS: This cross-sectional study was conducted on 250 men and 250 women from 30 different bodybuilding clubs. Participants were asked to complete a self-administered standardized anonymous check-list. RESULTS: Forty nine percent of the respondents declared supplement use. Men were more likely to take supplements than women (86.8% vs. 11.2%, p = 0.001). Reasons for using supplements were reported to be for health (45%), enhancing the immune system (40%) and improving athletic performance (25%). Most athletes (72%) had access to a nutritionist but underused this resource. Coaches (65%) had the greatest influence on supplementation practices followed by nutritionists (30%) and doctors (25%) after them. CONCLUSIONS: The prevalence of supplement use among bodybuilders was high. Sex, health-related issues and sport experts were determinant factors of supplement use. PMID:22973330

    Hashimoto's thyroiditis is a common auto-immune disorder. The most common presenting symptoms may include anxiety, negative mood, depression, dry skin, cold intolerance, puffy eyes, muscle cramps and fatigue, deep voice, constipation, slow thinking and poor memory. Clinical manifestations of the disease are defined primarily by low levels of thyroid hormones; therefore it is treated by hormone replacement therapy, which usually consists of levothyroxine (LT4). Selenium might reduce antibody levels and result in a decreased dosage of LT4 and may provide other beneficial effects (e.g. on mood and health-related quality of life). To assess the effects of selenium supplementation on Hashimoto's thyroiditis. We searched the following databases up to 2 October 2012: CENTRAL in The Cochrane Library (2012, Issue 10), MEDLINE, EMBASE, and Web of Science; we also screened reference lists of included studies and searched several online trial registries for ongoing trials (5 November 2012). Randomised controlled clinical trials that assessed the effects of selenium supplementation for adults diagnosed with Hashimoto's thyroiditis. Study selection, data extraction, assessment of risk of bias, and analyses were carried out by two independent review authors. We assessed the quality of the evidence of included studies using GRADE. We were unable to conduct a meta-analysis because clinical heterogeneity between interventions that were investigated is substantial. Four studies at unclear to high risk of bias comprising 463 participants were included. The mean study duration was 7.5 months (range 3 to 18 months). One of our primary outcomes-'change from baseline in health related quality of life'-and two of our secondary outcomes-'change from baseline in LT4 replacement dosage at end of the study' and 'economic costs'-were not assessed in any of the studies. One study at high risk of bias showed statistically significant improvement in subjective well-being with sodium

  10. OPERA, an automatic PSF reconstruction software for Shack-Hartmann AO systems: application to Altair

    Science.gov (United States)

    Jolissaint, Laurent; Veran, Jean-Pierre; Marino, Jose

    2004-10-01

    When doing high angular resolution imaging with adaptive optics (AO), it is of crucial importance to have an accurate knowledge of the point spread function associated with each observation. Applications are numerous: image contrast enhancement by deconvolution, improved photometry and astrometry, as well as real time AO performance evaluation. In this paper, we present our work on automatic PSF reconstruction based on control loop data, acquired simultaneously with the observation. This problem has already been solved for curvature AO systems. To adapt this method to another type of WFS, a specific analytical noise propagation model must be established. For the Shack-Hartmann WFS, we are able to derive a very accurate estimate of the noise on each slope measurement, based on the covariances of the WFS CCD pixel values in the corresponding sub-aperture. These covariances can be either derived off-line from telemetry data, or calculated by the AO computer during the acquisition. We present improved methods to determine 1) r0 from the DM drive commands, which includes an estimation of the outer scale L0 2) the contribution of the high spatial frequency component of the turbulent phase, which is not corrected by the AO system and is scaled by r0. This new method has been implemented in an IDL-based software called OPERA (Performance of Adaptive Optics). We have tested OPERA on Altair, the recently commissioned Gemini-North AO system, and present our preliminary results. We also summarize the AO data required to run OPERA on any other AO system.

  11. East Asian winter temperature variation associated with the combined effects of AO and WP pattern

    2016-04-01

    The combined effects of the Arctic Oscillation (AO) and Western Pacific (WP) teleconnection pattern on the East Asian winter monsoon (EAWM) over the last 56 years (1958/59-2013/2014) were investigated using NCEP/NCAR reanalysis data (Park and Ahn, 2015). The study results revealed that the effect of the AO on winter temperature in East Asia could be changed depending on the phases of the WP pattern in the North Pacific. The negative relationship between the EAWM and the AO increased when the AO and WP were in-phase with each other. Hence, when winter negative (positive) AO was accompanied by negative (positive) WP, negative (positive) temperature anomalies were dominant across the entire East Asia region. Conversely, when the AO and WP were of-of-phase, the winter temperature anomaly in East Asia did not show distinct changes. Furthermore, from the perspective of stationary planetary waves, the zonal wavenumber-2 patterns of sea level pressure and geopotential height at 500hPa circulation strengthened when the AO and WP were in-phase but were not significant for the out-of-phase condition. It explained the possible mechanism of the combined effects of the AO and WP on the circulation related to EAWM. Reference Park, H.-J., and J.-B.

    2008-08-01

    Hospital inpatients are frequently hypokalaemic. Low plasma potassium levels may cause life threatening complications, such as cardiac arrhythmias. Potassium supplementation may be administered parenterally or enterally. Oral potassium supplements have been associated with oesophageal ulceration, strictures and gastritis. An alternative to potassium salt tablets or solution is dietary modification with potassium rich food stuffs, which has been proven to be a safe and effective method for potassium supplementation. The potassium content of one medium banana is equivalent to a 12 mmol potassium salt tablet. Potassium supplementation by dietary modification has been shown to be equally efficacious to oral potassium salt supplementation and is preferred by the majority of patients. Subsequently, it is our practice to replace potassium using dietary modification, particularly in surgical patients having undergone oesophagogastrectomy or in those with peptic ulcer disease.

    The Fish and Wildlife Program of the Northwest Power Planning Council (NPPC) prescribes several approaches to achieve its goal of doubling the salmon and steelhead runs of the Columbia River. Among those approaches are habitat restoration, improvements in adult and juvenile passage at dams and artificial propagation. Supplementation will be a major part of the new hatchery programs. The purpose of the Regional Assessment of Supplementation Project (RASP) is to provide an overview of ongoing and planned supplementation activities, to construct a conceptual framework and model for evaluating the potential benefits and risks of supplementation and to develop a plan for better regional coordination of research and monitoring and evaluation of supplementation. RASP has completed its first year of work. Progress toward meeting the first year`s objectives and recommendations for future tasks are contained in this report.

    The aim of the experiment was to determine the effects of supplementation of di-calcium-phosphate in the form of blocks in late pregnancy (2 months before calving), on production and reproduction parameters of dairy cattle in smallholder farms. The experiment covered 63 animals in 20 smallholder farms, divided into control and supplemented groups. Results showed that mineral supplementation had a significant effect on calf weight, milk fat content and reproduction parameters. Calves born to cattle supplemented with di-calcium-phosphate were heavier by 1.67 kg than those in the control group. Similarly, the average milk fat content in the supplemented group was 5.6 g/L (P 0.05). (author)

    Grunewald, K K; Bailey, R S

    1993-02-01

    We conducted a survey of 624 commercially available supplements targeted towards bodybuilding athletes. Over 800 performance claims were made for these supplements. Supplements include amino acids, boron, carnitine, choline, chromium, dibencozide, ferulic acid, gamma oryzanol, medium chain triglycerides, weight gain powders, Smilax compounds and yohimbine. Many performance claims advertised were not supported by published research studies. In some instances, we found no research to validate the claims; in other cases, research findings were extrapolated to inappropriate applications. For example, biological functions of some non-essential compounds were interpreted as performance claims for the supplements. Claims for others were based on their ability to enhance hormonal release or activity. We suggest that more research be conducted on this group of athletes and their nutritional needs. Furthermore, the effectiveness and safety of supplements merit further investigation.

  16. Functional analysis of AoAtg11 in selective autophagy in the filamentous fungus Aspergillus oryzae.

    Science.gov (United States)

    Tadokoro, Takayuki; Kikuma, Takashi; Kitamoto, Katsuhiko

    2015-07-01

    Autophagy is a highly conserved cellular degradation process in eukaryotes and consists of both non-selective and selective types. Selective autophagic processes include pexophagy, mitophagy, and the cytoplasm-to-vacuole targeting (Cvt) pathway of yeast, in which particular vacuolar proteins, such as aminopeptidase I (Ape1), are selectively transported to vacuoles. Although selective autophagy has been mainly studied in the yeasts Saccharomyces cerevisiae and Pichia pastoris, there is evidence for selective autophagy in filamentous fungi; however, the details are poorly understood. In S. cerevisiae, Atg11 is a selective autophagy-specific protein that recognizes and transports substrates to the pre-autophagosomal structure (PAS). Here, we first identified an ATG11 homologue in the filamentous fungus Aspergillus oryzae and analyzed the localization of the corresponding protein, designated AoAtg11, fused to enhanced green fluorescent protein (EGFP). Imaging analysis revealed that AoAtg11-EGFP was localized to PAS-like structures. We next constructed an Aoatg11 disruptant of A. oryzae and showed that AoAtg11 is involved in pexophagy and mitophagy. In addition, AoAtg11 was found to be dispensable for non-selective autophagy and for transporting AoApe1 to vacuoles. Taken together, these results suggest that AoAtg11 is a selective autophagy-specific protein in A. oryzae, and has distinct molecular functions from that of S. cerevisiae Atg11.

    2017-01-01

    Background : The consumption of fruits, vegetables, and dietary supplements correlate. Most previous studies have aimed to identify the determinants of supplement uses or the distinct features of supplement users; this literature lacks a discussion on dietary supplement consumption as a predictor of fruit and vegetable consumption. Objective : This study examines how dietary supplement consumption correlates with fruit and vegetable consumption by combining scanner data and surveys of Korean household grocery shopping. Methods : Propensity score matching (PSM) is used to identify the relationship between dietary supplement consumption and fruit and vegetable consumption in a household. A logit regression using supplement consumption as the dependent variable is used. Then, the supplement takers (the treatment group) are matched with non-takers (the control group) based on the propensity scores estimated in the logit regression. The fruit and vegetable consumption levels of the groups are then compared. Results : We found that dietary supplement use is associated with higher fruit and vegetable consumption. This supports the health consciousness hypothesis based on attention bias, availability heuristics, the focusing effect, and the consumption episode effect. It rejects the health substitute hypothesis based on economic substitutes and mental accounting. Conclusions : Future research on the health benefits of dietary supplements should address the complementary consumption of fruits/vegetables and their health benefits to avoid misstating the health effects of supplements.

    Full Text Available More than 1400 herbal products or herbal-derived compounds are commonly commercialised for health uses worldwide (Tyler, 1996. Herbs are considered dietary supplements, and therefore are subjected to a very limited form of regulation, and advertisements normally highlight their potential activities without mentioning any side effect. Also, herbs are generally believed to be 'natural', and hence safe. Many nutritional supplements contains herb compounds usually not present in the diet (e.g. Ginko biloba, horse- chestnut, and only 10% of the herbs used in nutritional supplements are commonly present in the food (e.g. garlic, soy, blueberry, green the, ginger, curcuma (Eisenberg et al., 1993. There is much interest in "alternative natural approaches" in sport. It is appealing for athletes to use 'natural' substances with similar activity to 'pharmacological' ones in term of improving performance, are not considered doping, and are considered side-effects free (Table 1. Indeed, many herbal dietary supplements marketed on internet are presented as legal alternative to illicit drugs (Denneey et al., 2005.

They also occur in some plants, where they are known as phytoecdysteroids, and are believed to contribute to deter invertebrate predators. In insects, they regulate moulting and metamorphosis, may regulate reproduction and diapause. Most actions of ecdysteroids are mediated by intracellular receptor complexes, which regulate gene expression in a tissue- and development-specific manner (Lehmann et al 1989.Several phytoecdysteroids have anabolic growth-promoting effects on mice, rats, pigs and Japanese quails. Ecdysteroids stimulate muscle growth, and this anabolic effect promotes increased physical performance without training.

    The prevalence of dietary supplement use varies largely among populations, and previous studies have indicated that it is high in the Danish population compared with other European countries. The diversity in supplement use across countries indicates that cultural and environmental factors could influence the use of dietary supplements. Only few studies investigating the use of dietary supplements have been conducted in the Danish population. The present cross-sectional study is based on 54,948 Danes, aged 50-64 years, who completed self-administrated questionnaires on diet, dietary supplements and lifestyle between 1993 and 1997. A health index including smoking, physical activity, alcohol and diet, and a metabolic risk index including waist circumference, urinary glucose and measured hypertension were constructed. Logistic regression was used to investigate these determinants in relation to the intake of dietary supplements. We found that 71 % of the participants were dietary supplement users; female sex, older age groups and higher educated participants were more likely to be users of any dietary supplements. One additional point in the health index was associated with 19, 16 and 9 % higher likelihood of being user of any, more common and less common supplements, respectively. In the metabolic risk index, one additional point was associated with 17 and 16 % lower likelihood of being user of any supplement and more common supplements, respectively. No significant association was found for less common supplement use. In conclusion, those with the healthiest lifestyle were more likely to use dietary supplements. Thus, lifestyle and dietary composition should be considered as confounders on supplement use and health outcomes.

    2013-06-01

    Full Text Available OBJETIVO: Analisar instrumento de medição da adesão ao tratamento da hipertensão por meio da "Teoria da Resposta ao Item". MÉTODOS: Estudo analítico com 406 hipertensos com complicações associadas, atendidos na atenção básica em Fortaleza, CE, 2011, pela "Teoria da Resposta ao Item". As etapas de execução foram: teste de dimensionalidade, calibração dos itens; tratamento dos dados e construção da escala, analisadas com base no modelo de resposta gradual. Estudo da dimensionalidade do instrumento foi feito pela análise da matriz de correlação policórica e análise fatorial de informação completa. Utilizou-se o software Multilog para calibração dos itens e estimação dos escores. RESULTADOS: Os itens referentes ao tratamento medicamentoso foram os mais diretamente relacionados à adesão, enquanto aqueles referentes ao tratamento não medicamentoso precisam ser reformulados, pois possuíram menor quantidade de informação psicométrica e baixa discriminação. A independência dos itens, o reduzido número de níveis da escala e as baixas variâncias explicadas no ajuste dos modelos mostraram as principais fragilidades do instrumento analisado. A "Teoria da Resposta ao Item" mostrou-se relevante para análise, pois avaliou o respondente quanto à adesão ao tratamento da hipertensão, ao nível de dificuldade dos itens e à sua capacidade de discriminação entre indivíduos com diferentes níveis de adesão, o que gerou maior quantidade de informação. CONCLUSÕES: O instrumento analisado é limitado para medir a adesão ao tratamento da hipertensão, mediante análise pela "Teoria da Resposta ao Item", e necessita de ajustes. A adequada formulação dos itens é importante para medir precisamente o traço latente desejado.

    French, John M. T.; King, Matthew D.

    2017-01-01

    Current United States regulatory policies allow for the addition of pharmacologically active substances in dietary supplements if derived from a botanical source. The inclusion of certain nootropic drugs, such as vinpocetine, in dietary supplements has recently come under scrutiny due to the lack of defined dosage parameters and yet unproven short- and long-term benefits and risks to human health. This study quantified the concentration of vinpocetine in several commercially available dietary supplements and found that a highly variable range of 0.6–5.1 mg/serving was present across the tested products, with most products providing no specification of vinpocetine concentrations.

    This article reviews the current literature addressing the treatment of schizophrenia with vitamin supplementation. It describes the important roles that vitamins play in normal metabolism, and reviews the evidence pertaining to vitamin deficiency and supplementation in patients with schizophrenia. There is mounting evidence suggesting that vitamin supplementation, in particular with folic acid, vitamin B12 and vitamin D, may be important in treatment within certain subgroups of patients. There is a need for larger randomized controlled trials, and further studies examining the incidence of schizophrenia in countries with poor prenatal care and malnutrition, as well as in countries that have adopted mandatory folic acid fortification of grain products, are recommended.

    Full Text Available Testosterone has now become one of the most widely used medications throughout the world. The rapid growth of the testosterone market in the past 10 years is due to many factors. We currently have a worldwide aging population. In the US, the number of men 65 years old or older is increasing 2-3 times faster than the number of men younger than 65 years. In addition, poor general health and certain medical conditions such as diabetes/metabolic syndrome (MetS, cardiovascular disease (CVD, and osteoporosis have been associated with low serum testosterone levels. [1],[2],[3] There are now fewer concerns regarding the development of prostate cancer (PCa after testosterone therapy, making it a more attractive treatment option. Finally, the introduction of different forms of testosterone supplementation therapy (TST with increased promotion, marketing, and direct-to-consumer advertising is also driving market growth. As the demand for TST continues to grow, it is becoming more important for clinicians to understand how to diagnose and treat patients with low testosterone.

    Eating disorders (EDs) are a series of differentiated nosological entities sharing the common link of a continuous alteration in food intake or in food intake-related behavior. Within this classification, the following disorders are noteworthy: anorexia nerviosa (AN) and bulimia nerviosa (BN). Anorexia nervosa is a chronic disorder characterized mainly by negative or decreased food intake accompanied by a distortion of body image and intense accompanying fear of weight gain. The estimated vital prevalence of this disorder in adolescence is approximately 0.5%-1%.1 The primary feature of BN is the presence of binge eating accompanied by compensatory behavior (in the form of intense exercise and the use of laxatives and diuretics, etc.). The prevalence of BN is estimated to be between 2% and 4% in young women, and it generally starts at somewhat later stages than AN. It is believed that biological, psychological, and environmental factors, as well as genetic vulnerability, influence the pathogenesis of EDs. A variety of therapies exist, both biological and psychological, whose effectiveness is supported by the scientific literature. Nonetheless, we find these therapies only partially effective and new targets as well as new treatments should be sought. Although the etiopathogenesis of EDs is unclear, some of the neurobiological dysfunction found suggests that diet and nutrient supplementation could be relevant in their treatment. We review in this article new treatments focusing on nutritional deficits.

    2014-05-01

    Electronic cigarettes (e-cigarettes) have recently gained significant attention in the marketplace and in the media. However, limited information is available about the worldwide impact of e-cigarettes; most public health officials are calling for more data so they can more fully understand the potential risks and benefits of e-cigarettes in order to inform regulatory action. In the USA, e-cigarettes that are marketed as tobacco products are not currently regulated by the Food and Drug Administration (FDA). However, having a continuum of nicotine-containing products that cross jurisdictional lines within the FDA in the future would create the potential (and the need) for a comprehensive nicotine strategy at the FDA. As part of developing the most appropriate approach to e-cigarette regulation, FDA Center for Tobacco Products scientists have been reviewing the available literature to determine the state of e-cigarette knowledge and have identified research areas that could be addressed. This supplement provides a summary of the current knowledge and research gaps pertaining to e-cigarettes with regards to product design, chemistry and toxicology of e-liquid and aerosol constituents, human factor-based risk factors, abuse liability, clinical pharmacology and human health effects, paediatric issues, and environmental issues.

    The Energy Information Administration (EIA) of the US Department of Energy (DOE) is mandated by Congress to be the agency that collects, analyzes, and disseminates impartial, comprehensive data about energy including the volume consumed, its customers, and the purposes for which it is used. The Federal Buildings Supplemental Survey (FBSS) was conducted by EIA in conjunction with DOE`s Office of Federal Energy Management Programs (OFEMP) to gain a better understanding of how Federal buildings use energy. This report presents the data from 881 completed telephone interviews with Federal buildings in three Federal regions. These buildings were systematically selected using OFEMP`s specifications; therefore, these data do not statistically represent all Federal buildings in the country. The purpose of the FBSS was threefold: (1) to understand the characteristics of Federal buildings and their energy use; (2) to provide a baseline in these three Federal regions to measure future energy use in Federal buildings as required in EPACT; and (3) to compare building characteristics and energy use with the data collected in the CBECS.

    AFA-2G assemblies in Ling Ao NPS (LNPS) have been replaced gradually by AFA-3G assemblies from cycle 2 and subsequent cycles. the enrichment of the fuels will be increased from 3.2% to 3.7% from cycle 3 in Ling Ao. Therefore, the study of ling Ao mixed core and increased enrichment have been performed since 2001. Lots of accidents need to be re-analyzed in Ling Ao NPS in order to verify its safety requirements for the new fuel management. Control rod drop accident for LNPS was re-analyzed in 2001 in frame of FRAMATOME ANP analytical methodology. The analytical codes used in the accident analysis include SCIENCE, ESPADON, CINEMA, CANTAL and FLICA III. The control rod drop accident analysis is performed with respect to the 10 reference cycles of the generic fuel management design for Ling Ao mixed core and increased enrichment study. The pre-drop FδH for the first transition cycles and other cycles are 1.52 and 1.55, respectively. For detected dropped rod configurations, the negative flux rate protection system actuates a reactor trip. For the non-detected dropped rod configurations, the minimum DNBR values have been evaluated with conservative analysis methodology and assumptions and the DNBR fuel design limit is respected the analytical results shows that, for all the non-detected dropped rod configurations, the minimum DNB margin is about 2% which occurs in AFA-2G fuel assembly in the first transition cycle.

  14. Requirements Modeling with the Aspect-oriented User Requirements Notation (AoURN): A Case Study

    Science.gov (United States)

    Mussbacher, Gunter; Amyot, Daniel; Araújo, João; Moreira, Ana

    The User Requirements Notation (URN) is a recent ITU-T standard that supports requirements engineering activities. The Aspect-oriented URN (AoURN) adds aspect-oriented concepts to URN, creating a unified framework that allows for scenario-based, goal-oriented, and aspect-oriented modeling. AoURN is applied to the car crash crisis management system (CCCMS), modeling its functional and non-functional requirements (NFRs). AoURN generally models all use cases, NFRs, and stakeholders as individual concerns and provides general guidelines for concern identification. AoURN handles interactions between concerns, capturing their dependencies and conflicts as well as the resolutions. We present a qualitative comparison of aspect-oriented techniques for scenario-based and goal-oriented requirements engineering. An evaluation carried out based on the metrics adapted from literature and a task-based evaluation suggest that AoURN models are more scalable than URN models and exhibit better modularity, reusability, and maintainability.

  1. Dietary supplements and team-sport performance.

    Science.gov (United States)

    Bishop, David

    2010-12-01

    A well designed diet is the foundation upon which optimal training and performance can be developed. However, as long as competitive sports have existed, athletes have attempted to improve their performance by ingesting a variety of substances. This practice has given rise to a multi-billion-dollar industry that aggressively markets its products as performance enhancing, often without objective, scientific evidence to support such claims. While a number of excellent reviews have evaluated the performance-enhancing effects of most dietary supplements, less attention has been paid to the performance-enhancing claims of dietary supplements in the context of team-sport performance. Dietary supplements that enhance some types of athletic performance may not necessarily enhance team-sport performance (and vice versa). Thus, the first aim of this review is to critically evaluate the ergogenic value of the most common dietary supplements used by team-sport athletes. The term dietary supplements will be used in this review and is defined as any product taken by the mouth, in addition to common foods, that has been proposed to have a performance-enhancing effect; this review will only discuss substances that are not currently banned by the World Anti-Doping Agency. Evidence is emerging to support the performance-enhancing claims of some, but not all, dietary supplements that have been proposed to improve team-sport-related performance. For example, there is good evidence that caffeine can improve single-sprint performance, while caffeine, creatine and sodium bicarbonate ingestion have all been demonstrated to improve multiple-sprint performance. The evidence is not so strong for the performance-enhancing benefits of β-alanine or colostrum. Current evidence does not support the ingestion of ribose, branched-chain amino acids or β-hydroxy-β-methylbutyrate, especially in well trained athletes.

    Pregnancy is a challenge from the nutritional point of view, because nutrient requirements are increased and alter its intake can affect maternal and fetal health. Micronutrient defi ciency states are related to preeclampsia, intrauterine growth restriction, abortion and congenital anomalies. Currently, the diet of many expectant mothers is insufficient in micronutrients, in this cases supplementation is necessary. It is recommended supplementation with folic acid in doses of 400 mcg / day and 5 mg/day in risk pregnant, and should begin at least one month before conception and during the first 12 weeks gestation, and extend it throughout pregnancy in mothers with nutritional risk. It is important to keep watch the proper dose of folic acid to prevent possible adverse effects of unmetabolized accumulation in plasma. A high percentage of pregnant women presented iron deficiency anemia, being recommended intermittent use of iron supplements (with lower gastrointestinal alteration and oxidative stress); not recommended for mothers without anemia (hemoglobin> 13.5 g / L). Since calcium absorption is increased up to 40% in gestation, its supplementation is not recommended for mothers with adequate intakes (3 dairy / day), and its use must be reserved to women with inadequate intakes and / or high risk of preeclampsia. Regarding the iodine, there are confl icting positions by different working groups established potassium iodide supplementation in women who do not reach their recommended intake (3 servings of milk and dairy products + 2 g of iodized salt), with their diets. Given that vitamin A and D can be toxic to mother and fetus, it is not recommended its supplementation except in cases of deficiency. Although the use of multiple micronutrients supplements may favorably impact the outcome of pregnancy, more scientific evidence is needed to establish the replacement of iron and folic acid with a multiple micronutrient supplement.

  10. Calcium supplementation in osteoporosis: useful or harmful?

    Science.gov (United States)

    Chiodini, Iacopo; Bolland, Mark J

    2018-04-01

    Osteoporosis and fragility fractures are important social and economic problems worldwide and are due to both the loss of bone mineral density and sarcopenia. Indeed, fragility fractures are associated with increased disability, morbidity and mortality. It is known that a normal calcium balance together with a normal vitamin D status is important for maintaining well-balanced bone metabolism, and for many years, calcium and vitamin D have been considered crucial in the prevention and treatment of osteoporosis. However, recently, the usefulness of calcium supplementation (alone or with concomitant vitamin D) has been questioned, since some studies reported only weak efficacy of these supplementations in reducing fragility fracture risk. On the other hand, besides the gastrointestinal side effects of calcium supplements and the risk of kidney stones related to use of co-administered calcium and vitamin D supplements, other recent data suggested potential adverse cardiovascular effects from calcium supplementation. This debate article is focused on the evidence regarding both the possible usefulness for bone health and the potential harmful effects of calcium and/or calcium with vitamin D supplementation. © 2018 European Society of Endocrinology.

    2018-04-01

    Pr3+ doped YTiAO6 (A = Nb and Ta) compounds were prepared by conventional solid state ceramic route. X - ray diffraction studies of the samples confirmed the euxenite orthorhombic phase formation. Effect of Pr3+ doping on the optical and luminescence properties of YTiAO6 (A = Nb and Ta) were studied. The strong absorption in the UV region are due to the absorption by the host YTiAO6 (A = Nb and Ta) and all other peaks can be attributed to that of Pr3+. Host emission peaks are observed around 485 nm and 460 nm in all samples. The red emission observed at 614 nm in the doped samples corresponds to the 1D2 to 3H4 transition of Pr3+ ion. CIE colour coordinates and chromaticity values were also discussed.

Walp. destacam-se, respectivamente, pela severidade e ampla ocorrência o Cowpea severe mosaic virus (CPSMV e o Cowpea aphid-borne mosaic virus (CABMV. Portanto, objetivaram-se, no presente trabalho, obter e avaliar plantas de feijão-caupi com resistência ao CPSMV e ao CABMV, visando ao desenvolvimento de cultivares essencialmente derivadas e novas cultivares. Realizaram-se oito cruzamentos seguidos de retrocruzamentos, utilizando a linhagem TE 97-309G-9 e a cultivar Patativa como genitores resistentes, e as cultivares BR3-Tracuateua, BRS-Urubuquara, BRS-Novaera, BRS-Guariba e Pretinho como genitores suscetíveis. As gerações F2 e F2RC1 foram desafiadas quanto à resistência por meio de inoculação mecânica com isolados do CPSMV e do CABMV. Nas gerações F2RC1, além da resistência foram avaliados os caracteres: número de dias para o início da floração, comprimento das vagens, número de grãos. vagem-1, peso de cem grãos e produção de grãos.planta-1. Todos os indivíduos F2 e F2RC1 foram analisados pelo teste χ² e se ajustaram à frequência esperada de 15 plantas suscetíveis 1 planta resistente a ambos os vírus. As médias das plantas F2RC1 resistentes, de cada retrocruzamento, foram comparadas com a média do seu respectivo genitor recorrente pelo teste 't' e as médias dos retrocruzamentos foram comparadas pelo teste de Scott-Knott. Foi detectada variabilidade genética entre os retrocruzamentos para todos os caracteres. Todos os retrocruzamentos foram considerados promissores para produção de cultivares essencialmente derivadas resistentes ao CPSMV e ao CABMV e as plantas selecionadas possuem características que possibilitam a seleção de linhagens com grãos de bom padrão comercial e altamente produtivas.

As informações foram sistematizadas em três categorias de fatores que influenciam o RT e como facilitadores ou barreiras - de ordem pessoal, de ordem organizacional e relacionadas às características dos serviços, sistemas e políticas. RESULTADOS: Dos 633 artigos inicialmente levantados, 21 atenderam aos critérios de inclusão. Fatores identificados como mais relevantes: de ordem pessoal - dor, fatores psicossociais, afastamento do trabalho; organizacionais - modificações nos postos de trabalho, demanda psicológica do trabalho, apoio organizacional, apoio de colegas e da chefia; relacionados aos serviços, sistemas e políticas - programa de retorno ao trabalho, tempo de afastamento e serviços de apoio. CONCLUSÃO: O estudo evidenciou que o RT é um processo complexo, que demanda políticas intersetoriais, cooperação técnica e pactuação de metas entre os atores envolvidos no processo.

  15. Adesão ao Tratamento em Gestação de Alto Risco

    Full Text Available No Brasil, aproximadamente 15% das gestações são de alto risco, sendo os diagnósticos de diabetes gestacional e hipertensão as causas mais frequentes dessa condição. Para a efetividade dos tratamentos indicados nesses casos, bem como alcance de desfechos favoráveis, é essencial a adesão da paciente às recomendações fornecidas pelas equipes de saúde, o que torna fundamental a avaliação desse indicador. A pesquisa apresentada avaliou a adesão de participantes de um programa de atendimento interdisciplinar a gestantes de alto risco desenvolvido em um hospital geral privado por meio de três instrumentos: Questionário Morisky-Green de adesão ao uso de medicação, Questionário de Adesão ao Tratamento e Pergunta descritiva de avaliação qualitativa. Durante oito meses, 83 gestantes responderam aos questionários, que possibilitaram identificar níveis de adesão ao longo do tempo de participação no programa, situações de não adesão mais frequentes, bem como variáveis que interferem nas medidas de adesão ao uso de medicação e ao tratamento global. Considera-se que os índices levantados são passíveis de uso como indicadores clínicos e gerenciais, possibilitando a comprovação da efetividade e melhoria constante das rotinas de saúde. Tais mecanismos são úteis para definição de protocolos, discussão de casos clínicos e mesmo para feedbackàs próprias pacientes.

    XlnR is a Zn(II)2Cys6 transcriptional activator of xylanolytic and cellulolytic genes in Aspergillus. Overexpression of the aoxlnR gene in Aspergillus oryzae (A. oryzae xlnR gene) resulted in elevated xylanolytic and cellulolytic activities in the culture supernatant, in which nearly 40 secreted proteins were detected by two-dimensional electrophoresis. DNA microarray analysis to identify the transcriptional targets of AoXlnR led to the identification of 75 genes that showed more than fivefold increase in their expression in the AoXlnR overproducer than in the disruptant. Of these, 32 genes were predicted to encode a glycoside hydrolase, highlighting the biotechnological importance of AoXlnR in biomass degradation. The 75 genes included the genes previously identified as AoXlnR targets (xynF1, xynF3, xynG2, xylA, celA, celB, celC, and celD). Thirty-six genes were predicted to be extracellular, which was consistent with the number of proteins secreted, and 61 genes possessed putative XlnR-binding sites (5'-GGCTAA-3', 5'-GGCTAG-3', and 5'-GGCTGA-3') in their promoter regions. Functional annotation of the genes revealed that AoXlnR regulated the expression of hydrolytic genes for degradation of beta-1,4-xylan, arabinoxylan, cellulose, and xyloglucan and of catabolic genes for the conversion of D-xylose to xylulose-5-phosphate. In addition, genes encoding glucose-6-phosphate 1-dehydrogenase and L-arabinitol-4- dehydrogenase involved in D-glucose and L-arabinose catabolism also appeared to be targets of AoXlnR.

    Neonatal hyperbilirubinaemia is a common problem which carries a risk of neurotoxicity. Certain infants who have hyperbilirubinaemia develop bilirubin encephalopathy and kernicterus which may lead to long-term disability. Phototherapy is currently the mainstay of treatment for neonatal hyperbilirubinaemia. Among the adjunctive measures to compliment the effects of phototherapy, fluid supplementation has been proposed to reduce serum bilirubin levels. The mechanism of action proposed includes direct dilutional effects of intravenous (IV) fluids, or enhancement of peristalsis to reduce enterohepatic circulation by oral fluid supplementation. To assess the risks and benefits of fluid supplementation compared to standard fluid management in term and preterm newborn infants with unconjugated hyperbilirubinaemia who require phototherapy. We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 5), MEDLINE via PubMed (1966 to 7 June 2017), Embase (1980 to 7 June 2017), and CINAHL (1982 to 7 June 2017). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. We included randomised controlled trials that compared fluid supplementation against no fluid supplementation, or one form of fluid supplementation against another. We extracted data using the standard methods of the Cochrane Neonatal Review Group using the Covidence platform. Two review authors independently assessed the eligibility and risk of bias of the retrieved records. We expressed our results using mean difference (MD), risk difference (RD), and risk ratio (RR) with 95% confidence intervals (CIs). Out of 1449 articles screened, seven studies were included. Three articles were awaiting classification, among them, two completed trials identified from the trial registry appeared to be unpublished so far.There were

    Full Text Available O objetivo do presente trabalho foi acompanhar o desenvolvimento imunológico dos neonatos caninos, a fim de avaliar a imunidade celular pela análise dos leucócitos e linfócitos totais e das subpopulações de linfócitos T (CD4+ e CD8+ pela técnica de citometria de fluxo. Foram utilizados 30 cães neonatos de ambos os sexos, sem raça definida, aos três, 10, 17, 24, 31, 38 e 45 dias de idade. A contagem de leucócitos totais aos 45 dias (11.639±3.574 foi significativamente maior que no terceiro dia de idade (8.740±1.812 (P<0,05; não houve diferença entre a contagem total de linfócitos aos 45 dias em relação ao terceiro dia de idade. Quanto às subpopulações de LT CD4+ e LT CD8+, os percentuais de LT CD4+, aos três dias de idade (24,9±16,8%, foram inferiores quando comparados à média entre o 10°, o 24° e o 31°dia (35,5%, e os de CD8+, ao terceiro dia, menores em relação às médias do 10° e do 31° dia de idade. Pode-se concluir que as subpopulações de LT CD4+ e CD8+ sofrem oscilações durante o desenvolvimento pós-natal, sendo estas crescentes em relação aos níveis obtidos aos três dias de idade. A relação CD4+:CD8+ mostrou superioridade para o primeiro tipo celular, sendo que a maior relação entre CD4+ e CD8+ ocorreu no terceiro dia de idade. Com base nos resultados obtidos neste estudo, notaram-se as diferenças semanais nas populações linfocitárias, o que demonstra a dinâmica dessas células durante o período neonatal.

    Selenium is an essential component of selenoproteins, enzymes with extensive regulatory and protective effect in organism. Immunological effects of Se are documented and are distinct even above concentrations necessary for maximal activity of selenoenzymes. Therefore, we investigated effect of supplementation by 100 μg of yeast-bound Se on concentrations of thyroid autoantibodies TPOAb and TgAb in the group of 253 seniors living in the Asylum Houses of South Bohemia. Increase of serum selenium from 59 to 150 μg Se/L serum in supplemented group and from 59 to 72 μg Se/L serum in group with placebo were detected by Instrumental Neutron Activation Analysis (INAA) and proved increased Se intake during the trial. Autoantibodies were analyzed by ELISA at the beginning of the trial and after 1 year. Statistical evaluation of results in whole groups (regardless of increased autoantibodies) by ANOVA manifested significant decrease of TPOAb and TgAb in non-supplemented group while supplementation did not effect serum autoantibodies concentrations. Evaluation of groups of seniors created from those with increased autoantibodies, ANOVA demonstrated decrease of TPOAb in both groups but Se supplementation did not affect the decrease. In opposite, TgAb increased significantly and Se supplementation led to higher increase of TgAb. Recent results of possibility to decrease serum concentration of TPOAb proved this effect only for high TPOAb concentrations and for higher Se supplements. From this point of view, it is necessary to conduct subsequent trials with the patients with autoimmune thyreoiditis with different levels of autoantibodies and detect also serum Se levels. (author)

    Mahabaduge, Hasitha; Haslam, Jeanne

    Supplemental instruction utilizes peer-assisted study sessions to provide review sessions on course material and an opportunity to discuss and work out problems. The impact of supplemental instruction on student performance is well researched and used in a large number of universities around the world due to its proven success. However, the impact of the student leader who plays a significant role in this model is rarely discussed in the literature. We present a case study on the impact of student leader on the success of supplemental instruction model. This case study was done for an Introductory Physics course correlating student performance and the supplemental instruction sessions they attended. Further analysis revealed that the academic performance and work ethics of the student leader has a significant impact on the success of the supplemental instruction model. Important factors to consider when selecting a student leader, the challenges and possible remedies will also be discussed.

  4. Effects of adrenergic agents on the expression of zebrafish (Danio rerio) vitellogenin Ao1

    International Nuclear Information System (INIS)

    Yin Naida; Jin Xia; He Jiangyan; Yin Zhan

    2009-01-01

    Teleost vitellogenins (VTGs) are large multidomain apolipoproteins, traditionally considered to be estrogen-responsive precursors of the major egg yolk proteins, expressed and synthesized mainly in hepatic tissue. The inducibility of VTGs has made them one of the most frequently used in vivo and in vitro biomarkers of exposure to estrogen-active substances. A significant level of zebrafish vtgAo1, a major estrogen responsive form, has been unexpectedly found in heart tissue in our present studies. Our studies on zebrafish cardiomyopathy, caused by adrenergic agonist treatment, suggest a similar protective function of the cardiac expressed vtgAo1. We hypothesize that its function is to unload surplus intracellular lipids in cardiomyocytes for 'reverse triglyceride transportation' similar to that found in lipid transport proteins in mammals. Our results also demonstrated that zebrafish vtgAo1 mRNA expression in heart can be suppressed by both α-adrenergic agonist, phenylephrine (PE) and β-adrenergic agonist, isoproterenol (ISO). Furthermore, the strong stimulation of zebrafish vtgAo1 expression in plasma induced by the β-adrenergic antagonist, MOXIsylyl, was detected by Enzyme-Linked ImmunoSorbent Assay (ELISA). Such stimulation cannot be suppressed by taMOXIfen, an antagonist to estrogen receptors. Thus, our present data indicate that the production of teleost VTG in vivo can be regulated not only by estrogenic agents, but by adrenergic signals as well.

    Valéria Marta Ribeiro Soares

    2017-03-01

    Full Text Available Os contos policiais, de Luiz Lopes Coelho, advogado paulista, são pouco conhecidos. Este trabalho visa analisar o conto Do êxtase ao crime?, tan-to do ponto de vista estético quanto lingüístico. No ângulo literário, serão analisados os elementos que fazem dele uma ficção policial e, no aspecto lin-güístico, serão destacados os termos latinos que causam uma singularidade na obra e ajudam a interpretá-la. Contistas do gênero policial no Brasil são muito raros, devido ao rótulo dado por muitos eruditos de tal gênero ser “uma das mais limitadas entre as formas populares de ficção”. Do êxtase ao crime? pode dar ao leitor uma nova visão desse gênero, pois o autor consegue aliar o engenho e a arte na escolha dos vocábulos, especialmente, os latinos, e na criação do mistério, suspense e situações imprevistas do conto em ques-tão.

    Adaptive optics (AO) and optical coherence tomography (OCT) are powerful imaging modalities that, when combined, can provide high-resolution (3.5 {micro}m isotropic), 3-D images of the retina. The AO-OCT system at UC Davis has demonstrated the utility of this technology for microscopic, volumetric, in vivo retinal imaging. The current system uses an AOptix bimorph deformable mirror (DM) for low-order, high-stroke correction and a 140-actuator Boston Micromachines DM for high-order correction. Developments to improve performance or functionality of the instrument are on-going. Based on previous work in system characterization we have focused on improved AO control. We present preliminary results and remaining challenges for a newly implemented Fourier transform reconstructor (FTR). The previously reported error budget analysis is also reviewed and updated, with consideration of how to improve both the amount of residual error and the robustness of the system. Careful characterization of the AO system will lead to improved performance and inform the design of future systems.

  16. Reproducibility of the Lauge-Hansen, Danis-Weber, and AO classifications for ankle fractures

    Directory of Open Access Journals (Sweden)

    Lucas Lopes da Fonseca

    Full Text Available ABSTRACT Objective: This study evaluated the reproducibility of the three main classifications of ankle fractures most commonly used in emergency clinical practice: Lauge-Hansen, Danis-Weber, and AO-OTA. The secondary objective was to assess whether the level of professional experience influenced the interobserver agreement for the classification of this pathology. Methods: The study included 83 digitized preoperative radiographic images of ankle fractures, in anteroposterior and lateral views, of different adults that had occurred between January and December 2013. For sample calculation, the estimated accuracy was approximately 15%, with a sampling error of 5% and a sampling power of 80%. The images were analyzed and classified by six different observers: two foot and ankle surgeons, two general orthopedic surgeons, and two-second-year residents in orthopedics and traumatology. The Kappa statistical method of multiple variances was used to assess the variations. Results: The Danis-Weber classification indicated that 40% of the agreements among all observers were good or excellent, whereas only 20% of good and excellent agreements were obtained using the AO and Lauge Hansen classifications. The Kappa index was 0.49 for the Danis-Weber classification, 0.32 for Lauge Hansen, and 0.38 for AO. Conclusion: The Hansen-Lauge classification presented the poorest interobserver agreement among the three systems. The AO classification demonstrated a moderate agreement and the Danis-Weber classification presented an excellent interobserver agreement index, regardless of professional experience.

  17. Practical Recommendations on Supplemental Feeding Introduction

    2015-01-01

    Full Text Available Despite the availability of a national consensus document describing in detail modern approaches to feeding infants, pediatricians keep on giving most diverse recommendations on the time of supplemental feeding introduction. The article presents a brief historical review, as well the modern view on the issue of introduction of supplemental feeding to children. In the previous century, it was common both in Russia and most European countries to introduce supplemental feeding to children at the age of 2 or even 1.5 months. In 2002, the World Health Organization put forward an initiative in support of breastfeeding and recommended not to introduce supplemental feeding before the age of 6 months. A certain “golden mean” has apparently been achieved on the basis of results of studies and a longterm discussion among the specialists in feeding from different countries — all scientific communities and national recommendations of most countries define the optimal age for supplemental feeding introduction as “from 4 (completed months to 6 (completed months” with certain individual approach. 

  18. Vitamin supplementation benefits in master athletes.

    Brisswalter, Jeanick; Louis, Julien

    2014-03-01

    Master athletes are more than 35 years of age and continue to train as hard as their young counterparts despite the aging process. All life long, they are capable of accomplishing exceptional sporting performances. For these participants in endurance events, matching energy intake and expenditure is critical to maintain health and performance. The proportions of carbohydrate, fat, and protein must be optimized to provide enough calories to sustain the energy requirements of competition or training, and for recovery. In addition, endurance athletes must include adequate vitamins and minerals in their diets to maintain healthy immune function. Vitamins and minerals may be sufficient in the diets of endurance athletes, who have a high energy intake. This would make it unnecessary to use vitamin and mineral supplements. Furthermore, one major limitation for these athletes is the management of oxidative stress, which, when in excess, can be deleterious for the organism. For individuals exposed to oxidative stress, micronutritional supplementations rich in vitamins and minerals can be also an alternative strategy. Although these supplementations are increasingly used by master athletes, very few data are available on their effects on oxidative stress, muscle recovery, and physical performance. The potential benefits of supplement use in athletes are thus questionable. Some studies indicate no benefits, while others highlight potential negative side effects of vitamin supplementation. Additional studies are warranted in order to design adapted prescriptions in antioxidant vitamins and minerals.

    Inverse correlations have been found in most studies on the relationship between dietary intake and plasma concentrations of carotenoids on one side and degenerative diseases such as cancer and cardiovascular diseases on the other side. Protective effects of carotenoids have been found for pathologies of the retina and the skin. Concentrations of these molecules in blood are lower in digestive pathologies and HIV. Short- and long-term toxicity of carotenoids was found to be low. In combination with the beneficial effects found for diets rich in carotenoids, this has initiated trials with relatively high doses of carotenoid supplements. In the study in Linxian (China) in a rural population with poor nutritional status, supplementation with beta-carotene, zinc, selenium and vitamin E lowered total mortality and mortality from stomach cancer. Other studies (ATBC, Caret.) on well-fed subjects did not show beneficial effects on mortality from cancer and cardiovascular diseases. On the contrary, higher mortality and lung cancer incidence was found in supplemented subjects that were also exposed to asbestos and cigarette smoke. In these studies, doses of supplemental beta-carotene were high and varied from 20 to 50 mg/day. One still ongoing study, called Suvimax, doses subjects for eight years with a cocktail of vitamins and minerals including 6 mg per day of beta-carotene. This supplementation with physiologically seen more "normal" doses might give clarity on the question if beta-carotene is the protective factor in fruits and vegetables.

  20. Creatine and Caffeine: Considerations for Concurrent Supplementation.

    Trexler, Eric T; Smith-Ryan, Abbie E

    2015-12-01

    Nutritional supplementation is a common practice among athletes, with creatine and caffeine among the most commonly used ergogenic aids. Hundreds of studies have investigated the ergogenic potential of creatine supplementation, with consistent improvements in strength and power reported for exercise bouts of short duration (≤ 30 s) and high intensity. Caffeine has been shown to improve endurance exercise performance, but results are mixed in the context of strength and sprint performance. Further, there is conflicting evidence from studies comparing the ergogenic effects of coffee and caffeine anhydrous supplementation. Previous research has identified independent mechanisms by which creatine and caffeine may improve strength and sprint performance, leading to the formulation of multi-ingredient supplements containing both ingredients. Although scarce, research has suggested that caffeine ingestion may blunt the ergogenic effect of creatine. While a pharmacokinetic interaction is unlikely, authors have suggested that this effect may be explained by opposing effects on muscle relaxation time or gastrointestinal side effects from simultaneous consumption. The current review aims to evaluate the ergogenic potential of creatine and caffeine in the context of high-intensity exercise. Research directly comparing coffee and caffeine anhydrous is discussed, along with previous studies evaluating the concurrent supplementation of creatine and caffeine.

    2003-04-01

    To describe the usefulness of some of the most common tertiary references that healthcare professionals employ to answer requests about herbal and dietary supplements. All requests for information on herbal and dietary supplements received by the drug information service between April and September 2000 were evaluated. Each question was independently reviewed by 4 clinicians using a 4-point scale; 14 references were searched for appropriate answers. The percent of responses for each of the possible scores for each reference overall and by category of question was reported to determine the most helpful references for answering the broadest range of questions. Fifty questions regarding herbal and dietary supplements were analyzed. The electronic databases (Natural Medicine Comprehensive Database, Micromedex) and the Internet site (The Natural Pharmacist) were determined to be overall the most helpful references for providing information on herbal and dietary supplements. The Natural Therapeutics Pocket Guide was the most helpful book reference. These results will facilitate the retrieval of useful information on herbal and dietary supplements and enable healthcare professionals to determine appropriate allocation of resources as they build a drug information library for handling requests about these products.

    Full Text Available Ana Močić Pavić, Iva Hojsak Referral Center for Pediatric Gastroenterology and Nutrition, Children's Hospital Zagreb, Zagreb, Croatia Background: In recent years prebiotics have been added to infant formula to make it resemble breast milk more closely and to promote growth and development of beneficial intestinal microbiota. This review aims to present new data on the possible positive effects of prebiotics in infant formula on intestinal microbiota (bifidogenic and lactogenic effect and on clinical outcomes including growth, infections, and allergies. With that aim, a literature search of the Cochrane Central Register of Controlled Trials (CENTRAL, EMBASE, Scopus, PubMed/Medline, Web of Science, and Science Direct in the last 10 years (December 2003 to December 2013 was performed. Results: Altogether 24 relevant studies were identified. It was found that during intervention, prebiotics can elicit a bifidogenic and lactogenic effect. As far as clinical outcomes were concerned, 14 studies investigated the effect of infant formula supplemented with prebiotics on growth and found that there was no difference when compared with non-supplemented infant formula. All available data are insufficient to support prebiotic supplementation in order to reduce risk of allergies and infections. Conclusion: There is currently no strong evidence to recommend routine supplementation of infant formulas with prebiotics. Further well-designed clinical studies with long-term follow-up are needed. Keywords: prebiotics, infant formula, growth, allergy, infections, supplementation

    Full Text Available Curaçao, one of the five islands of the Dutch Caribbean federation called the Netherlands Antilles, currently stands at a crossroad of constitutional reform. In the context of these changes at the political level, it is logical that national identities are being redefined and repositioned. The developments in the fashioning of national identities in Curaçao deserve attention locally but also regionally. How do people in Curaçao construct national identities in daily life? How is a national collective constructed on the one hand, and how are differences with other collectivities constructed on the other hand? The historical context of constitutional changes that have occurred over the years is considered as well as an examination of the present discourse on constitutional reform. These identity issues are then placed within a wider Caribbean context.  Resumen: La complejidad de la construcción de la identidad nacional en Curaçao,en el Caribe holandés Curaçao, una de las cinco islas de la federación caribeña neerlandesa llamada Antillas Holandesas, se encuentra hoy en día en una encrucijada de reformas constitucionales. En el contexto de estos cambios a nivel político, es lógico que las identidades nacionales sean redefinidas y reposicionadas. Los desarrollos en la formulación de identidades nacionales en Curaçao merecen atención local, y también regional. ¿Cómo construye la gente en Curaçao identidades nacionales en la vida cotidiana? ¿Cómo, por un lado, se construye el colectivo nacional y, por otro, cómo se construyen las diferencias con otras colectividades? En este análisis se estudia el contexto histórico de los cambios constitucionales que han ocurrido en el curso del tiempo y se realiza igualmente una revisión del actual discurso sobre la reforma constitucional. Estos problemas de identidad son analizados entonces en un contexto caribeño más amplio.

    Full Text Available Desastres associados ao transporte marinho e terrestre de hidrocarbonetos causam sérios impactos aos ambientes costeiros, afetando a fauna e a flora marinha, além de prejudicar diversas atividades econômicas, inclusive àquelas tradicionais, como é o caso da pesca artesanal. Assim, faz-se necessário conhecer a geologia e a geomorfologia da costa, em especial as praias devido à elevada dinâmica e vulnerabilidade desses ambientes. A construção de megaempreendimentos na zona costeira e o tráfego de navios petroleiros e pequenas embarcações, ou mesmo a implantação de dutos, localizados junto à linha de costa, representam uma ameaça ao equilíbrio dos ecossistemas. Para tal, foram analisados diversos aspectos da geomorfologia costeira de Maricá, para posterior identificação do grau de sensibilidade deste litoral a eventos de derramamento de óleo, a partir do Índice de Sensibilidade Ambiental (ISA proposto pelo Ministério do Meio Ambiente. O litoral de Maricá, ao longo de 34 km de extensão entre Itaipuaçú (no extremo oeste e Ponta Negra (a leste, apresenta quatro áreas distintas quanto à sensibilidade à poluição decorrente de derramamento de óleo, sendo: ISA1, para as áreas de costões rochosos localizados nas extremidades leste e oeste deste litoral; ISA4, para a quase totalidade das praias, formadas por areias quartzosas grossa e média, exceto o extremo-oeste de Itaipuaçú, que possui areia muito grossa e cascalhos sendo, portanto, representada pelo ISA5; e ISA10, para as lagoas costeiras e canais na retaguarda das barreiras arenosas, sujeitas à contaminação por meio dos canais e por transposição por grandes ondas de tempestades. Os índices compreendem os extremos dessa classificação, devido à grande variedade de elementos na paisagem costeira de Maricá e mostra a elevada sensibilidade deste litoral, frente à ameaça de desastres causados por derramamento de óleo.

    Full Text Available OBJETIVO: investigar o nível de consciência dos pais em relação à importância da triagem auditiva neonatal, bem como verificar os motivos do não comparecimento ao retorno agendado após a primeira avaliação. MÉTODO: a casuística foi constituída por 31 mães e/ou responsáveis dos recém-nascidos da unidade neonatal do Hospital Universitário de Maringá, os quais não compareceram ao reteste agendado após a alta hospitalar. RESULTADOS: os motivos apresentados pelas mães e/ou responsáveis para o não comparecimento ao retorno agendado envolveram atitudes que puderam sinalizar pouca importância atribuída às questões relacionadas à audição e a Triagem Auditiva Neonatal, pois sugiram motivos irrelevantes como o esquecimento do retorno, mãe pensou que o bebê não deixaria ser submetido ao exame e a perda de horário para nova avaliação. Tal fato, provavelmente reflete a falta de conscientização por parte das mães dos recém-nascidos quanto à importância da Triagem Auditiva Neonatal. CONCLUSÃO: existe a necessidade de aumentar a conscientização geral em relação à Triagem Auditiva Neonatal, por parte dos familiares e dos profissionais que atuam diretamente com os recém-nascidos, os quais contribuirão para a agilidade do processo diagnóstico, garantindo melhores perspectiva ao futuro de crianças portadoras de deficiência auditiva.

Biótipo de Eleusine indica originado do Mato Grosso com suspeita de resistência aos herbicidas inibidores de ACCase foi avaliado em casa de vegetação na sua suscetibilidade para diversos produtos do grupo dos ariloxifenoxipropionatos e cicloexanodionas. Estudos de resposta à dose confirmaram que o biótipo era 18 vezes mais insensível ao sethoxydim do que biótipo suscetível nunca aspergido com herbicidas. Também se constatou resistência cruzada ao fenoxaprop, cyhalofop, propaquizafop e butroxydim. Não se observou resistência cruzada aos produtos fluazifop, haloxyfop, quizalofop e clethodim.Among the causes for weed control inefficacy, the worst one is resistance to herbicides. The objectives of this work were to evaluate an Eleusine indica biotype suspected of resistance to ACCase inhibitors and to investigate the occurrence of cross- resistance to several ACCase inhibitors. One biotype of Eleusine indica originated from Mato Grosso with suspected resistance to ACCase inhibitors was evaluated in a greenhouse in relation to its susceptibility to several products of the ariloxyphenoxypropionate and cyclohexanedione groups. Studies on dose response confirmed that the suspected biotype was 18 times more insensitive to sethoxydim than the susceptible biotype that had never been treated with herbicides. Cross-resistance was confirmed for fenoxaprop, cyhalofop, propaquizafop and butroxydim. No cross-resistance was observed with fluazifop, haloxyfop, quizalofop, and clethodim.

    Representing 3%-5% of shoulder girdle injuries scapula fractures are rare. Furthermore, approximately 1% of scapula fractures are intraarticularfractures of the glenoid fossa. Because of uncertain fracture morphology and limited experience, the treatment of glenoid fossa fractures is difficult. The glenoid fracture classification by Ideberg (1984) and Euler (1996) is still commonly used in literature. In 2013 a new glenoid fracture classification was introduced by the AO. The purpose of this study was to examine the new AO classification in clinical practice in comparison with the classifications by Ideberg and Euler. In total CT images of 84 patients with glenoid fossa fractures from 2005 to 2018 were included. Parasagittal, paracoronary and axial reconstructions were examined according to the classifications of Ideberg, Euler and the AO by 3 investigators (orthopedic surgeon, radiologist, student of medicine) at three individual time settings. Inter- and intraobserver reliability of the three classification systems were ascertained by computing Inter- and Intraclass (ICCs) correlation coefficients using Spearman's rank correlation coefficient, 95%-confidence intervals as well as F-tests for correlation coefficients. Inter- and intraobserver reliability for the AO classification showed a perspicuous coherence (R = 0.74 and R = 0.79). Low to moderate intraobserver reliability for Ideberg (R = 0.46) and Euler classification (R = 0.41) was found.

    Full Text Available Fish oil and conjugated linoleic acid (CLA belong to a popular class of food supplements known as “fat supplements”, which are claimed to reduce muscle glycogen breakdown, reduce body mass, as well as reduce muscle damage and inflammatory responses. Sport athletes consume fish oil and CLA mainly to increase lean body mass and reduce body fat. Recent evidence indicates that this kind of supplementation may have other side-effects and a new role has been identified in steroidogenensis. Preliminary findings demonstrate that fish oil and CLA may induce a physiological increase in testosterone synthesis. The aim of this review is to describe the effects of fish oil and CLA on physical performance (endurance and resistance exercise, and highlight the new results on the effects on testosterone biosynthesis. In view of these new data, we can hypothesize that fat supplements may improve the anabolic effect of exercise.

    2011-01-01

    Full Text Available Calcium and vitamin D supplements reverse secondary hyperparathyroidism and are widely prescribed to prevent osteoporotic fractures, with proven antifracture efficacy when targeted to individuals with documented insufficiencies. Men who should particularly be considered for calcium and vitamin D supplements include elderly or institutionalized individuals, patients with documented osteoporosis on antiresorptive or anabolic medication, and individuals receiving glucocorticoids. Benefits are most apparent when a daily dose of 1000–1200 mg calcium is complemented with 800 IU vitamin D. Compliance is the key to optimizing clinical efficacy. While (conventionally dosed vitamin D has not been associated with safety concerns, recent meta-analytic data have provided evidence to suggest that calcium supplements (without coadministered vitamin D may potentially be associated with cardiovascular risks.

    In this article we review the current literature addressing the treatment of schizophrenia with vitamin supplementation. We first describe the important roles that vitamins play in normal metabolism, then review the evidence pertaining to vitamin deficiency and supplementation in patients with schizophrenia. We then describe mounting evidence suggesting that vitamin supplementation, in particular with folic acid, vitamin B12 and vitamin D, may be important in treatment within certain subgroups of patients. We highlight the need for larger, randomized controlled trials, and recommend further studies examining the incidence of schizophrenia in countries with poor prenatal care and malnutrition, as well as in countries that have adopted mandatory folic acid fortification of grain products.

    Dietary supplements are a global business worth more than US$100 billion annually. These supplements are taken by up to 50% of adults and perhaps one-third of children in economically advanced economies. Definitions of dietary supplements differ from country to country, and regulation is generally lax and often seems to be directed more toward promoting commerce than protecting public health. Supplements may directly cause toxic reactions or may interact with other supplements or pharmaceuticals. Some supplements are found to have been contaminated with heavy metals, and others do not contain the expected quantities of active ingredients. In general, supplements are not needed except in cases of established deficiencies, and excess of some nutrients can increase cancer rates. There are important public health reasons for taking some supplements, including folate and iodine in pregnancy. This review discusses the public health concerns associated with dietary supplements and suggests directions for further regulation.

  14. Vitamin A supplementation for cystic fibrosis.

    People with cystic fibrosis and pancreatic insufficiency are at risk of fat soluble vitamin deficiency as these vitamins (A, D, E and K) are co-absorbed with fat. Thus, some cystic fibrosis centres routinely administer these vitamins as supplements but the centres vary in their approach of addressing the possible development of deficiencies in these vitamins. Vitamin A deficiency causes predominantly eye and skin problems while supplementation of vitamin A to excessive levels may cause harm to the respiratory and skeletal systems in children. Thus a systematic review on vitamin A supplementation in people with cystic fibrosis would help guide clinical practice. To determine if vitamin A supplementation in children and adults with cystic fibrosis:1. reduces the frequency of vitamin A deficiency disorders;2. improves general and respiratory health;3. increases the frequency of vitamin A toxicity. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search of the Group's Cystic Fibrosis Trials Register: 07 April 2014. All randomised or quasi-randomised controlled trials comparing all preparations of oral vitamin A used as a supplement compared to either no supplementation (or placebo) at any dose and for any duration, in children or adults with cystic fibrosis (defined by sweat tests or genetic testing) with and without pancreatic insufficiency. No relevant studies for inclusion were identified in the search. No studies were included in this review. As there were no randomised or quasi-randomised controlled trials identified, we cannot draw any conclusions on the benefits (or otherwise) of regular administration of vitamin A in people with cystic fibrosis. Until further data are available, country or region specific guidelines on the use of

  15. The Risks and Benefits of Calcium Supplementation

    Full Text Available The association between calcium supplementation and adverse cardiovascular events has recently become a topic of debate due to the publication of two epidemiological studies and one meta-analysis of randomized controlled clinical trials. The reports indicate that there is a significant increase in adverse cardiovascular events following supplementation with calcium; however, a number of experts have raised several issues with these reports such as inconsistencies in attempts to reproduce the findings in other populations and questions concerning the validity of the data due to low compliance, biases in case ascertainment, and/or a lack of adjustment. Additionally, the Auckland Calcium Study, the Women's Health Initiative, and many other studies included in the meta-analysis obtained data from calcium-replete subjects and it is not clear whether the same risk profile would be observed in populations with low calcium intakes. Dietary calcium intake varies widely throughout the world and it is especially low in East Asia, although the risk of cardiovascular events is less prominent in this region. Therefore, clarification is necessary regarding the occurrence of adverse cardiovascular events following calcium supplementation and whether this relationship can be generalized to populations with low calcium intakes. Additionally, the skeletal benefits from calcium supplementation are greater in subjects with low calcium intakes and, therefore, the risk-benefit ratio of calcium supplementation is likely to differ based on the dietary calcium intake and risks of osteoporosis and cardiovascular diseases of various populations. Further studies investigating the risk-benefit profiles of calcium supplementation in various populations are required to develop population-specific guidelines for individuals of different genders, ages, ethnicities, and risk profiles around the world.

    2017-08-22

    Cystic fibrosis is a genetic disorder which can lead to multiorgan dysfunction. Malabsorption of fat and fat-soluble vitamins (A, D, E, K) may occur and can cause subclinical deficiencies of some of these vitamins. Vitamin K is known to play an important role in both blood coagulation and bone formation. Supplementation with vitamin K appears to be one way of addressing the deficiency, but there is very limited agreement on the appropriate dose and frequency of use of these supplements. This is an updated version of the review. To assess the effects of vitamin K supplementation in people with cystic fibrosis and to determine the optimal dose and route of administration of vitamin K for both routine and therapeutic use. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Most recent search: 30 January 2017. Randomised and quasi-randomised controlled trials of all preparations of vitamin K used as a supplement compared to either no supplementation (or placebo) at any dose or route and for any duration, in children or adults diagnosed with cystic fibrosis (by sweat test or genetic testing). Two authors independently screened papers, extracted trial details and assessed their risk of bias. Two trials (total of 32 participants) each lasting one month were included in the review and were assessed as having a moderate risk of bias. One was a dose-ranging parallel group trial in children (aged 8 to 18 years); and the other (with an older cohort) had a cross-over design comparing supplements to no treatment, but no separate data were reported for the first intervention period. Neither of the trials addressed any of the primary outcomes (coagulation, bone formation and quality of life). Both trials reported the restoration of serum vitamin K and undercarboxylated osteocalcin

    Otitis media is inflammation of the middle ear and is usually caused by infection. It affects people of all ages but is particularly common in young children. Around 164 million people worldwide have long-term hearing loss caused by this condition, 90% of them in low-income countries. As zinc supplements prevent pneumonia in disadvantaged children, we wanted to investigate whether zinc supplements could also prevent otitis media. To evaluate whether zinc supplements prevent otitis media in adults and children of different ages. We searched CENTRAL (2014, Issue 1), MEDLINE (1950 to February week 4, 2014) and EMBASE (1974 to March 2014). Randomised, placebo-controlled trials of zinc supplements given at least once a week for at least a month for preventing otitis media. Two review authors independently assessed the eligibility and methodological quality of the included trials and extracted and analysed data. We summarised results using risk ratios (RRs) or rate ratios for dichotomous data and mean differences (MDs) for continuous data. We combined trial results where appropriate. No new trials were identified for inclusion in this update. We identified 12 trials for inclusion, 10 of which contributed outcomes data. There were a total of 6820 participants. In trials of healthy children living in low-income communities, two trials did not demonstrate a significant difference between the zinc-supplemented and placebo groups in the numbers of participants experiencing an episode of definite otitis media during follow-up (3191 participants); another trial showed a significantly lower incidence rate of otitis media in the zinc group (rate ratio 0.69, 95% confidence interval (CI) 0.61 to 0.79, n = 1621). A small trial of 39 infants undergoing treatment for severe malnutrition suggested a benefit of zinc for the mean number of episodes of otitis media (mean difference (MD) -1.12 episodes, 95% CI -2.21 to -0.03). Zinc supplements did not seem to cause any serious adverse

    Hematological patients often present anorexia which along with other secondary effects from the chemotherapy and/or radiotherapy treatments compromise their nutritional status. Oral supplementation can aid to fulfill the energy and protein requirements of these patients. Nevertheless, the use of commercial nutritional supplements normally available, is limited by its poor intake. To evaluate the degree of fulfillment of the prescribed supplements and fulfillment of energy requirements, as well as the development of nutritional status in hematological patients hospitalized for treatment with chemotherapy and/or radiotherapy. Prospective, randomized and open study of inpatients at the hematological ward. Patients were randomized sequentially and they were assigned into 3 different nutritional interventions providing: Group 1 (G1), a flavored supplement; Group 2 (G2): a non flavored (neutral) supplement and Group 3 (G3): "kitchen" foods as supplements. Need and amount of nutritional supplements were provided according to the oral intake previously analyzed. Nutritional assessment (at admission and discharge) was based in the Subjective Global Assessment test (SGA), Risk Nutritional Index (RNI) and percentage of lost weight. Both fulfillment of supplement intake and achievement of energetic requirements were analyzed. 125 patients of 51.3 +/- 16.8 years; 45% men and 55% women. 54% lymphoma, 33% leukemia, 8% myeloma and others 4%. Length of stay (LOS): 7.0 +/- 3.6 d. The nutritional assessment done by SGA showed significant negative changes in G2 and G3 (G1: 30% developed malnutrition and 28% improved their nutritional status, p = NS; G2: 50% developed malnutrition against 7% whom improved their nutritional status, p = 0.002; y G3: 37% developed malnutrition against 21% whom improved their nutritional status, p = 0.02). According to RNI, patients evolved negatively from their nutritional state but no significant differences were found within groups (G1, from 81% of

    Background Vitamin D deficiency or insufficiency is thought to be common among pregnant women. Vitamin D supplementation during pregnancy has been suggested as an intervention to protect against adverse gestational outcomes. Objectives To examine whether supplements with vitamin D alone or in combination with calcium or other vitamins and minerals given to women during pregnancy can safely improve maternal and neonatal outcomes. Search methods We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 October 2011), the International Clinical Trials Registry Platform (ICTRP) (31 October 2011), the Networked Digital Library of Theses and Dissertations (28 October 2011) and also contacted relevant organisations (8 April 2011). Selection criteria Randomised and quasi-randomised trials with randomisation at either individual or cluster level, evaluating the effect of supplementation with vitamin D alone or in combination with other micronutrients for women during pregnancy. Data collection and analysis Two review authors independently i) assessed the eligibility of studies against the inclusion criteria ii) extracted data from included studies, and iii) assessed the risk of bias of the included studies. Data were checked for accuracy. Main results The search strategy identified 34 potentially eligible references. We included six trials assessing a total of 1023 women, excluded eight studies, and 10 studies are still ongoing. Five trials involving 623 women compared the effects of vitamin D alone versus no supplementation/placebo and one trial with 400 women compared the effects of vitamin D and calcium versus no supplementation. Only one trial with 400 women reported on pre-eclampsia: women who received 1200 IU vitamin D along with 375 mg of elemental calcium per day were as likely to develop pre-eclampsia as women who received no supplementation (average risk ratio (RR) 0.67; 95% confidence interval (CI) 0.33 to 1.35). Data from four trials

    Poor nutrition occurs frequently in people with cystic fibrosis and is associated with other adverse outcomes. Oral calorie supplements are used to increase total daily calorie intake and improve weight gain. However, they are expensive and there are concerns they may reduce the amount of food eaten and not improve overall energy intake. This is an update of a previously published review. To establish whether in people with cystic fibrosis, oral calorie supplements: increase daily calorie intake; and improve overall nutritional intake, nutritional indices, lung function, survival and quality of life. To assess adverse effects associated with using these supplements. We searched the Cochrane Cystic Fibrosis Trials Register comprising references from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We contacted companies marketing oral calorie supplements.Last search: 18 October 2016. Randomised or quasi-randomised controlled trials comparing use of oral calorie supplements for at least one month to increase calorie intake with no specific intervention or additional nutritional advice in people with cystic fibrosis. We independently selected the included trials, assessed risk of bias and extracted data. We contacted the authors of included trials and obtained additional information for two trials. We identified 21 trials and included three, reporting results from 131 participants lasting between three months and one year. Two trials compared supplements to additional nutritional advice and one to no intervention. Two of the included trials recruited only children. In one trial the risk of bias was low across all domains, in a second trial the risk of bias was largely unclear and in the third mainly low. Blinding of participants was unclear in two of the trials. Also, in one trial the clinical condition of groups appeared to be unevenly balanced at baseline and in another trial there were

    Full Text Available The present study evaluates the efficiency of different sulfur sources for ruminant nutrition. The fiber digestibility and the amino acid profile were analyzed in the duodenal digesta of crossbred steers fed Brachiaria dictyoneurahay. The sources utilized were elemental sulfur (ES70S, elemental sulfur (ES98S; calcium sulfate in hydrated (HCS, CaSO4.2H2O, and anhydrous (ACS, CaSO4, forms; and ammonium sulfate (AS, (NH42SO4, keeping a nitrogen:sulfur ratio of 11:1. The iso-protein supplements had 50% of protein in the total dry matter (DM. Five Holstein × Zebu steers, which were fistulated in the rumen and abomasum, were distributed in a 5 × 5 Latin square. The different sulfur sources in the supplement did not affect any of the evaluated nutritional factors, such as intake of hay dry matter and protein supplement, crude protein (CP, neutral detergent fiber corrected for ash and protein (NDFap, organic matter (OM, non-fibrous carbohydrate (NFC, ether extract (EE, total digestible nutrients (TDN, NDFap and CP digestibility coefficients, ruminal pH, and ruminal ammonia concentration. The concentrations of amino acids available in the abomasal digesta did not differ significantly in the tested diets. The sulfur sources evaluated in the present study are suitable as supplement for cattle, and their employment may be important to avoid environmental contaminations.

    Consumer demand for health information and health services has rapidly evolved to capture and even propel the movement to online health information seeking. Seventeen percent (52 million) of health information internet users will look for information about memory loss, dementia and Alzheimer's disease (AD) (Fox Pew Internet & American life project: Online health search. Report. Pew Research Center. http://pewinternet.org/Reports/2006/Online-Health-Search-2006.aspx 2006, Pew Research Center. http://pewinternet.org/Reports/2011/HealthTopics.aspx 2011). We examined the content of the 25 most frequently retrieved websites marketing AD dietary supplements. We found that the majority of websites and their products claimed AD-related benefits, including improvement and enhancement of function, treatment for AD, prevention of AD, maintenance of function, delayed progression of AD, and decreased symptoms. Supplements were described as effective, natural, powerful or strong, dependable and pure or of high quality. Peer reviewed references to proper scientific studies were infrequent on websites. Statements highlighting the risks of dietary supplements were as common as statements mitigating or minimizing these risks. Different strategies were used to promote supplements such as popular appeals and testimonials. Further enforcement of relevant policy is needed and preparation of clinicians to deal with requests of patients and caregivers is indicated.

    Peña-Rosas, Juan Pablo; De-Regil, Luz Maria; Dowswell, Therese; Viteri, Fernando E

    2014-01-01

    Background Anaemia is a frequent condition during pregnancy, particularly among women from developing countries who have insufficient iron intake to meet increased iron needs of both the mother and the fetus. Traditionally, gestational anaemia has been prevented with the provision of daily iron supplements throughout pregnancy, but adherence to this regimen due to side effects, interrupted supply of the supplements, and concerns about safety among women with an adequate iron intake, have limited the use of this intervention. Intermittent (i.e. one, two or three times a week on non-consecutive days) supplementation with iron alone or in combination with folic acid or other vitamins and minerals has recently been proposed as an alternative to daily supplementation. Objectives To assess the benefits and harms of intermittent supplementation with iron alone or in combination with folic acid or other vitamins and minerals to pregnant women on neonatal and pregnancy outcomes. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (23 March 2012). We also searched the WHO International Clinical Trials Registry Platform (ICTRP) for ongoing studies and contacted relevant organisations for the identification of ongoing and unpublished studies (23 March 2012). Selection criteria Randomised or quasi-randomised trials. Data collection and analysis We assessed the methodological quality of trials using standard Cochrane criteria. Two review authors independently assessed trial eligibility, extracted data and conducted checks for accuracy. Main results This review includes 21 trials from 13 different countries, but only 18 trials (with 4072 women) reported on our outcomes of interest and contributed data to the review. All of these studies compared daily versus intermittent iron supplementation. Three studies provided iron alone, 12 iron+folic acid and three more iron plus multiple vitamins and minerals. Their methodological quality was mixed

  17. Isolation and characterization of an agaro-oligosaccharide (AO-hydrolyzing bacterium from the gut microflora of Chinese individuals.

    Directory of Open Access Journals (Sweden)

    Miaomiao Li

    Full Text Available Agarose (AP from red algae has a long history as food ingredients in East Asia. Agaro-oligosaccharides (AO derived from AP have shown potential prebiotic effects. However, the human gut microbes responsible for the degradation of AO and AP have not yet been fully investigated. Here, we reported that AO and AP can be degraded and utilized at various rates by fecal microbiota obtained from different individuals. Bacteroides uniformis L8 isolated from human feces showed a pronounced ability to degrade AO and generate D-galactose as its final end product. PCR-DGGE analysis showed B. uniformis to be common in the fecal samples, but only B. uniformis L8 had the ability to degrade AO. A synergistic strain, here classified as Escherichia coli B2, was also identified because it could utilize the D-galactose as the growth substrate. The cross-feeding interaction between B. uniformis L8 and E. coli B2 led to exhaustion of the AO supply. Bifidobacterium infantis and Bifidobacterium adolescentis can utilize one of the intermediates of AO hydrolysis, agarotriose. Growth curves indicated that AO was the substrate that most favorably sustained the growth of B. uniformis L8. In contrast, κ-carrageenan oligosaccharides (KCO, guluronic acid oligosaccharides (GO, and mannuronic acid oligosaccharides (MO were found to be unusable to B. uniformis L8. Current results indicate that B. uniformis L8 is a special degrader of AO in the gut microbiota. Because B. uniformis can mitigate high-fat-diet-induced metabolic disorders, further study is required to determine the potential applications of AO.

    2014-01-01

    Background Iron and folic acid supplementation has been the preferred intervention to improve iron stores and prevent anaemia among pregnant women, and it may also improve other maternal and birth outcomes. Objectives To assess the effects of daily oral iron supplements for pregnant women, either alone or in conjunction with folic acid, or with other vitamins and minerals as a public health intervention. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (2 July 2012). We also searched the WHO International Clinical Trials Registry Platform (ICTRP) (2 July 2012) and contacted relevant organisations for the identification of ongoing and unpublished studies. Selection criteria Randomised or quasi-randomised trials evaluating the effects of oral preventive supplementation with daily iron, iron + folic acid or iron + other vitamins and minerals during pregnancy. Data collection and analysis We assessed the methodological quality of trials using standard Cochrane criteria. Two review authors independently assessed trial eligibility, extracted data and conducted checks for accuracy. Main results We included 60 trials. Forty-three trials, involving more than 27,402 women, contributed data and compared the effects of daily oral supplements containing iron versus no iron or placebo. Overall, women taking iron supplements were less likely to have low birthweight newborns (below 2500 g) compared with controls (8.4% versus 10.2%, average risk ratio (RR) 0.81; 95% confidence interval (CI) 0.68 to 0.97, 11 trials, 8480 women) and mean birthweight was 30.81 g greater for those infants whose mothers received iron during pregnancy (average mean difference (MD) 30.81; 95% CI 5.94 to 55.68, 14 trials, 9385 women). Preventive iron supplementation reduced the risk of maternal anaemia at term by 70% (RR 0.30; 95% CI 0.19 to 0.46, 14 trials, 2199 women) and iron deficiency at term by 57% (RR 0.43; 95% CI 0.27 to 0.66, seven trials, 1256 women

    In the design of KRT system in Ling Ao Ⅱ, it requires the hardware composition shall be similar to that of Ling Ao Ⅰ. At the same time, the KRT system should be digitized and centralized. In order to realize the goal, the KRT system will be divided into the lower and upper parts. The local sensor at the lower part will transform the analog signal to digital signal in the local display unit; then the digital signals are sent to the upper part (cabinet) by RS-485; the cabinet collects the signals, saves and displays them in the server or operation workstation. or sends them to the DCS. On the other hand, the digital signals will be treated into analog or on/off signals in cabinet and transmitted to other systems. (authors)

    A crítica de Hegel ao formalismo da moral kantiana é um tema que pode ser abordado de diferentes modos. Esta tese demonstra que tanto na filosofia de Kant, quanto na de Hegel, os argumentos decisivos em relação ao formalismo (Kant) e a sua necessária superação (Hegel) estão desenvolvidos na filosofia especulativa. A superioridade crítica de Hegel em relação à Kant consiste na sua radicalidade. Demonstra-se como para Hegel o próprio finito, o fenômeno, já é um não não-finito, revelando a sua c...

    2013-12-01

    Full Text Available Meu objetivo neste artigo é discutir o significado do conceito de efervescência na obra durkheimiana e apontar o papel que esse processo desempenha em relação à sua teoria moral. De modo geral, a argumentação versa em torno da articulação de três pressupostos estruturais da teoria moral durkheimiana, quais sejam, 1 a vinculação entre sagrado e ideal moral, 2 a concepção acerca da natureza humana como sendo essencialmente dual e 3 a proposta normativa de Durkheim de institucionalização de uma moralidade laica. Ao final, proponho ao leitor uma reflexão sobre a pertinência de sua defesa de um "sagrado laico" a partir dos desafios morais que caracterizam o mundo contemporâneo.

  6. Adaptive optics stochastic optical reconstruction microscopy (AO-STORM) by particle swarm optimization.

    Tehrani, Kayvan F; Zhang, Yiwen; Shen, Ping; Kner, Peter

    2017-11-01

    Stochastic optical reconstruction microscopy (STORM) can achieve resolutions of better than 20nm imaging single fluorescently labeled cells. However, when optical aberrations induced by larger biological samples degrade the point spread function (PSF), the localization accuracy and number of localizations are both reduced, destroying the resolution of STORM. Adaptive optics (AO) can be used to correct the wavefront, restoring the high resolution of STORM. A challenge for AO-STORM microscopy is the development of robust optimization algorithms which can efficiently correct the wavefront from stochastic raw STORM images. Here we present the implementation of a particle swarm optimization (PSO) approach with a Fourier metric for real-time correction of wavefront aberrations during STORM acquisition. We apply our approach to imaging boutons 100 μm deep inside the central nervous system (CNS) of Drosophila melanogaster larvae achieving a resolution of 146 nm.

    2018-01-01

    Full Text Available Several studies show the importance of serum vitamin D sufficient levels to prevent multiple chronic diseases. However, vitamin D supplementation and its effects on urine calcium excretion remain controversial. The objective of this prospective and interventional study was to evaluate urine calcium excretion in women with normal calciuria or hypercalciuria, once serum vitamin D sufficiency was achieved. We studied 63 women with idiopathic hypercalciuria, (9 with renal lithiasis and 50 normocalciuric women. Both groups had serum vitamin D levels low (deficiency or insufficiency. Baseline urine calcium excretion was measured before being supplemented with vitamin D2 or D3 weekly or vitamin D3 100.000 IU monthly. Once serum vitamin D levels were corrected achieving at least 30 ng/ml, a second urine calcium excretion was obtained. Although in the whole sample we did not observe significant changes in urine calcium excretion according to the way of supplementation, some of those with weekly supplementation had significant higher urine calcium excretion, 19% (n = 12 of hypercalciuric women and 12% (n = 6 of the normocalciuric group. Monthly doses, also showed higher urine calcium excretion in 40% of hypercalciuric women (n = 4/10 and in 44% (n = 4/9 of the renal lithiasis hypercalciuric patients. In conclusion, different ways of vitamin D supplementation and adequate serum levels are safe in most patients, although it should be taken into account a subgroup, mainly with monthly loading doses, that could increase the calciuria significantly eventually rising renal lithiasis risk or bone mass loss, if genetically predisposed.

  9. Coenzyme Q supplementation in pulmonary arterial hypertension

    Directory of Open Access Journals (Sweden)

    Jacqueline Sharp

    2014-01-01

    Full Text Available Mitochondrial dysfunction is a fundamental abnormality in the vascular endothelium and smooth muscle of patients with pulmonary arterial hypertension (PAH. Because coenzyme Q (CoQ is essential for mitochondrial function and efficient oxygen utilization as the electron carrier in the inner mitochondrial membrane, we hypothesized that CoQ would improve mitochondrial function and benefit PAH patients. To test this, oxidized and reduced levels of CoQ, cardiac function by echocardiogram, mitochondrial functions of heme synthesis and cellular metabolism were evaluated in PAH patients (N=8 in comparison to healthy controls (N=7, at baseline and after 12 weeks oral CoQ supplementation. CoQ levels were similar among PAH and control individuals, and increased in all subjects with CoQ supplementation. PAH patients had higher CoQ levels than controls with supplementation, and a tendency to a higher reduced-to-oxidized CoQ ratio. Cardiac parameters improved with CoQ supplementation, although 6-minute walk distances and BNP levels did not significantly change. Consistent with improved mitochondrial synthetic function, hemoglobin increased and red cell distribution width (RDW decreased in PAH patients with CoQ, while hemoglobin declined slightly and RDW did not change in healthy controls. In contrast, metabolic and redox parameters, including lactate, pyruvate and reduced or oxidized gluthathione, did not change in PAH patients with CoQ. In summary, CoQ improved hemoglobin and red cell maturation in PAH, but longer studies and/or higher doses with a randomized placebo-controlled controlled design are necessary to evaluate the clinical benefit of this simple nutritional supplement.

    2013-12-17

    Herbal dietary supplements made from saw palmetto (Serenoa repens; Arecaceae) fruit are commonly consumed to ameliorate benign prostate hyperplasia. A novel DNA mini-barcode assay to accurately identify [specificity = 1.00 (95% confidence interval = 0.74-1.00); sensitivity = 1.00 (95% confidence interval = 0.66-1.00); n = 31] saw palmetto dietary supplements was designed from a DNA barcode reference library created for this purpose. The mini-barcodes were used to estimate the frequency of mislabeled saw palmetto herbal dietary supplements on the market in the United States of America. Of the 37 supplements examined, amplifiable DNA could be extracted from 34 (92%). Mini-barcode analysis of these supplements demonstrated that 29 (85%) contain saw palmetto and that 2 (6%) supplements contain related species that cannot be legally sold as herbal dietary supplements in the United States of America. The identity of 3 (9%) supplements could not be conclusively determined.

    Saw palmetto supplements are one of the most commonly consumed supplements by men with prostate cancer and/or benign prostatic hyperplasia (BPH). Some studies have found significant improvements in BPH and lower urinary tract symptoms (LUTS) with saw palmetto supplementation, whereas others found no benefits. The variation in the efficacy in these trials may be a result of differences in the putative active components, fatty acids and phytosterols, of the saw palmetto supplements. To this end, we quantified the major fatty acids (laurate, myristate, palmitate, stearate, oleate, linoleate) and phytosterols (campesterol, stigmasterol, β-sitosterol) in 20 commercially available saw palmetto supplements using GC-FID and GC-MS, respectively. Samples were classified into liquids, powders, dried berries, and tinctures. Liquid saw palmetto supplements contained significantly higher (p saw palmetto supplements may be the best choice for individuals who want to take a saw palmetto supplement with the highest concentrations of both fatty acids and phytosterols.

    Full Text Available O objetivo deste trabalho foi avaliar a sensibilidade da goiabeira 'Pedro Sato' ao ozônio (O3, em comparação à cultivar Paluma, descrita como sensível. Oito plantas de cada cultivar foram submetidas separadamente a ar filtrado e a ar filtrado + O3, cinco horas por dia, durante quatro dias. Foram avaliadas fotossíntese (Asat, injúrias foliares visíveis e concentração de antocianinas e taninos. Plantas das duas cultivares também foram expostas, durante três meses, a condições ambientais em local contaminado por O3, tendo-se avaliado fotossíntese, injúrias foliares e crescimento. Plantas fumigadas com O3 apresentaram redução de Asat e da atividade fotoquímica, além de manifestação de injúrias foliares. 'Paluma' apresentou maior redução de Asat, injúrias foliares mais severas e redução de taninos. Quando exposta ao ambiente contaminado, 'Paluma' apresentou trocas gasosas mais altas, mas apresentou redução de Asat 30 dias antes que 'Pedro Sato'. O crescimento não foi afetado em 'Pedro Sato', cujas injúrias foliares tiveram menor incidência, severidade e precocidade do que em 'Paluma'. A menor taxa de crescimento de 'Paluma' indica maior sensibilidade ao O3. Apesar de responder com menor intensidade ao estresse induzido pelo O3, a cultivar Pedro Sato não pode ser considerada tolerante, pois apresenta danos fotoquímicos, injúrias foliares e alterações nos conteúdos de metabólitos secundários quando exposta a esse poluente.

  14. Bridging FPGA and GPU technologies for AO real-time control

    Perret, Denis; Lainé, Maxime; Bernard, Julien; Gratadour, Damien; Sevin, Arnaud

    2016-07-01

    Our team has developed a common environment for high performance simulations and real-time control of AO systems based on the use of Graphics Processors Units in the context of the COMPASS project. Such a solution, based on the ability of the real time core in the simulation to provide adequate computing performance, limits the cost of developing AO RTC systems and makes them more scalable. A code developed and validated in the context of the simulation may be injected directly into the system and tested on sky. Furthermore, the use of relatively low cost components also offers significant advantages for the system hardware platform. However, the use of GPUs in an AO loop comes with drawbacks: the traditional way of offloading computation from CPU to GPUs - involving multiple copies and unacceptable overhead in kernel launching - is not well suited in a real time context. This last application requires the implementation of a solution enabling direct memory access (DMA) to the GPU memory from a third party device, bypassing the operating system. This allows this device to communicate directly with the real-time core of the simulation feeding it with the WFS camera pixel stream. We show that DMA between a custom FPGA-based frame-grabber and a computation unit (GPU, FPGA, or Coprocessor such as Xeon-phi) across PCIe allows us to get latencies compatible with what will be needed on ELTs. As a fine-grained synchronization mechanism is not yet made available by GPU vendors, we propose the use of memory polling to avoid interrupts handling and involvement of a CPU. Network and Vision protocols are handled by the FPGA-based Network Interface Card (NIC). We present the results we obtained on a complete AO loop using camera and deformable mirror simulators.

    We present the overall statistical results from the Robo-AO Kepler planetary candidate survey, comprising of 3857 high-angular resolution observations of planetary candidate systems with Robo-AO, an automated laser adaptive optics system. These observations reveal previously unknown nearby stars blended with the planetary candidate host stars that alter the derived planetary radii or may be the source of an astrophysical false positive transit signal. In the first three papers in the survey, we detected 440 nearby stars around 3313 planetary candidate host stars. In this paper, we present observations of 532 planetary candidate host stars, detecting 94 companions around 88 stars; 84 of these companions have not previously been observed in high resolution. We also report 50 more-widely separated companions near 715 targets previously observed by Robo-AO. We derive corrected planetary radius estimates for the 814 planetary candidates in systems with a detected nearby star. If planetary candidates are equally likely to orbit the primary or secondary star, the radius estimates for planetary candidates in systems with likely bound nearby stars increase by a factor of 1.54, on average. We find that 35 previously believed rocky planet candidates are likely not rocky due to the presence of nearby stars. From the combined data sets from the complete Robo-AO KOI survey, we find that 14.5 ± 0.5% of planetary candidate hosts have a nearby star with 4″, while 1.2% have two nearby stars, and 0.08% have three. We find that 16% of Earth-sized, 13% of Neptune-sized, 14% of Saturn-sized, and 19% of Jupiter-sized planet candidates have detected nearby stars.

    The purpose of this study was to assess the reliability of the AO (Association for the Study of Internal Fixation) classification of distal radius fracture, using plain radiographs and 2 cross-sectional computed tomographic (CT) surface images. Five observers independently classified 32 distal radius fractures into 9 groups under AO classification. We established 4 methods for observation. First, using only two-directional radiographs; second, four-directional radiographs; third, CT (axial view) with four-directional radiographs; and fourth, CT (axial and sagittal views) with four-directional radiographs. Kappa statistics were used to establish the relative level of agreement between the observers. Interobserver reliability was poor in both first and second methods in which only plain radiographs were used (κ=0.30 and 0.23, respectively). Furthermore, reliability did not increase in the third method with the addition of 1 CT surface image (κ=0.29). In the fourth method, with the addition of 2 cross-sectional CT surface images, the reliability increased to a moderate level (κ=0.44). Interobserver reliability of the AO system of the classification of distal radius fractures was observed on using 2 cross-sectional CT surface images with four-directional radiographs. (author)

    The American public receives conflicting messages from dietitians, nutritionists, physicians, and manufacturers regarding food supplements. Consumers commonly distrust scientists and justify supplement use based upon word of mouth and friendship patterns. Scientific-based education regarding supplement use is vital in the present atmosphere where consumer misinformation is rampant.

    2016-02-01

    Full Text Available RESUMO Objetivo: Identificar e analisar fatores de risco associados ao estrabismo, dados oftalmológicos e antecedentes pessoais e familiares. Métodos: Estudo prospectivo, descritivo e analítico realizado com 240 pacientes que consultaram pela primeira vez nos ambulatórios de estrabismo. Foram avaliadas a frequência e associação entre estrabismo, dados de exames oftalmológicos e antecedentes pessoais e familiares para identificação dos fatores de risco. Resultados: Observou-se maior prevalência de estrabismo em mulheres (56,96% em relação aos homens (43,02%. A faixa etária mais atendida no ambulatório de estrabismo foi composta de crianças até 15 anos de idade (83,54%. Encontrou-se mais esotropia (55,27% que exotropia (42,20% e parcela menor de estrabismo vertical isolado (2,53%. A prematuridade foi associada ao estrabismo convergente (p=0,023 e não ao divergente (p=0,086. O diabetes mellitus materno foi associado à esotropia (p=0,024 e exotropia (p=0,036 no filho, mas a hipertensão arterial materna, uso de medicamentos para hipertensão e diabetes durante a gravidez e drogas ilícitas não foram estatisticamente significativos. Pacientes com paralisia cerebral tiveram mais associação com exotropia (p=0,008 que esotropia (p=0,019. Malformações congênitas, consanguinidade entre os pais e traumas oculares não apresentaram associação estatisticamente significativa para o estrabismo. A maioria dos pacientes com estrabismo apresentou boa acuidade visual corrigida e fundoscopia normal. Na análise de proporções a hipermetropia foi mais frequente na esotropia (68,7%. Conclusão: Os fatores de riscos internos e externos podem interferir na formação e desenvolvimento do olho na fase de plasticidade ocular, com prejuízo da binocularidade visual, podendo resultar em estrabismo. Há divergências com relação aos fatores de risco realmente associados e mais estudos são necessários para a identificação.

    Full Text Available O presente trabalho diz respeito a estudos realizados com o objetivo de observar a influência da luz solar sôbre a capacidade germinativa da semente despolpada de café e verificar, portanto, a possibilidade de se efetuar a seca desta semente exclusivamente ao sol. Além de um ensaio preliminar, foram efetuados mais outros dois, compreendendo, ao todo, duas secas ao sol, duas em um secador a baixa temperatura (±28°C, uma a sombra e uma em um secador a alta temperatura (±40°C. Pelas correlações entre as porcentagens de germinação e de umidade, que foram estabelecidas após diferentes períodos de secagem, foram tiradas as duas seguintes conclusões, que são as principais com relação ao objetivo dêstes ensaios : 1 Os raios solares são prejudiciais à capacidade germinativa da semente de café; sua nocividade acha-se, porém, intimamente ligada ao teor de umidade na semente. 2 À vista da conclusão acima, verifica-se que a semente despolpada de café e, muito provavelmente, também a não despolpada, podem ser perfeitamente sêcas a pleno sol sem que haja prejuízo para sua vitalidade, uma vez que sejam recolhidas antes que o seu teor de umidade caia abaixo do ponto crítico de 8% - 9%.In this paper the author deals with the question related to the coffee seed drying, with special attention to the effect of the sun radiations on seed viability. Based on the results obtained, the following conclusions were drawn : (a The sun rays have no specific influence on the viability of hulled coffee seed ; their effect is indirect and related to loss of moisture by the seed. (b Coffee seed can be dried in the sunlight without loss of viability if the water content does not drop under 8% to 9%. Below this critical level seed germination falls rapidly. (c The moisture content of coffee seed dried „in the sun may fall to about 7% in a short time with the consequent injury to viability. (d Under most conditions in the state of São Paulo

    Full Text Available A frequência dos portadores de alergia ao leite de vaca tem-se tornado alarmante. Relatórios epidemiológicos recentes demonstraram que um dos motivos mais preocupantes para ocorrência desse tipo de alergia é a presença da beta-lactoglobulina no leite. Os agravos a saúde incluem hipersensibilização do sistema imunológico, problemas gastrointestinais, cutâneos, respiratórios, e quando mais graves, surgem os eventos anafiláticos. No presente trabalho estudamos a alergenicidade ao leite de vaca frente aos mecanismos envolvidos na sensibilização dos sistema imunológico, diagnósticos e perspectivas biotecnológicas, através da análise de 52 artigos associados a essa problematização. Os resultados da análise baseados na alergenicidade ao leite de vaca revelaram a existência de uma diversidade de sintomas inespecíficos que corroboram no retardamento do diagnóstico. Além disso, foi possível perceber que a maioria dos protocolos de diagnósticos baseam-se estritamente na restrição do leite e seus derivados. Apesar das dificuldades enfrentadas no diagnóstico correto e tratamento eficaz, muitos estudos seguem em desenvolvimento utilizando tecnologias visando a correção da hipersensibilização do sistema imunológico provocada pelos alergénos do leite, edição/interferência da transcrição gênica e, consequentemente, alterando a tradução. Nesse sentido, tais processos poderão contribuir para redução e/ou eliminação da alergenicidade ao leite de vaca no cotidiano dos portadores dessa condição.

Após nascimento das ninhadas, foi avaliado na prole masculina adulta aos 60 e 90 dias de vida, o número de espermátides e a produção espermática diária nos testículos e o tempo de trânsito espermático no epidídimo. A exposição não foi capaz de promover alterações na produção espermática diária (DSP e no número de espermátides produzidas pelo testículo dos ratos expostos aos frutos verdes da S. lycocarpum durante a gestação e início da lactação. Não foram observadas alterações no tempo de trânsito espermático na cabeça do epidídimo, porém, foi constatado menor número de espermatozóides no corpo/cauda do epidídimo nos machos experimentais com 90 dias de vida, provavelmente resultante do menor tempo de trânsito espermático observado no corpo/cauda do epidídimo aos PND 90. Estes dados sugerem que a exposição de ratos aos frutos verdes da S. lycocarpum durante a gestação e início da lactação, não foi suficiente para promover alterações na produção mas sim no trânsito espermático, indicando possível alteração no eixo hormônio liberador das gonadotrofinas hipotálamo-hipófise-gônada

  6. Sobre o ódio ao professor Entrevista com Fernando Penna

    Fernando Penna

    2016-01-01

    Full Text Available Ao tomar a decisão de pautar o tema da violência para compor o dossiê do terceiro número de Movimento – revista eletrônica de educação da Universidade Federal Fluminense –, o Conselho Editorial elencou um grande número de facetas da violência que historicamente se manifestam física e presencialmente no interior e fora do espaço escolar. O fenômeno relativamente recente das redes sociais e o vertiginoso processo de crescimento de trocas de informação, interação e mediação virtual a ele agregado, não apenas ampliou o espectro da violência como contribuiu decisivamente para articular o dentro e o fora da escola. Dentre outros exemplos, talvez o mais comum e antigo é o registro de cenas reais de alunos e alunas brigando nos pátios escolares ou nas redondezas da instituição postadas nas redes sociais, muitas delas viralizadas – para usar o barbarismoda ocasião – por um número sempre crescente de adeptos do bullying escolar. Nos últimos cinco anos, nas redes sociais, o exemplo de articulação da violência dentro-fora da escola que mais chama a atenção é o ódio ao professor, conforme observa o professor Fernando Penna na entrevista que publicamos a seguir. Estudioso da manifestação reivindicatória por uma escola sem ideologia trazida nos últimos anos por setores conservadores e reacionários da sociedade brasileira, Penna busca oferecer na entrevista algumas hipóteses para compreendermos o fenômeno do ódio ao professor, bem como algumas pistas para apreendermos os fundamentos que movem aqueles setores no combate ao que denominam de doutrinação ideológica de esquerda, e, concluindo, observa a urgência da resistência ao assédio moral feito dos conservadores ereacionários, chamando a atenção para a importância da ampliação do conhecimento crítico sobre o tema.

    2009-03-01

    Full Text Available Abstract Background Achromobacter sp. AO22 (formerly Alcaligenes sp. AO22, a bacterial strain isolated from a lead-contaminated industrial site in Australia, was previously found to be resistant to moderate to high levels of mercury, copper and other heavy metals. However, the nature and location of the genetic basis for mercuric ion resistance in this strain, had not been previously identified. Findings Achromobacter sp. AO22 contains a functional mer operon with all four essential genes (merRTPA and shows >99% DNA sequence identity to that of Tn501. The mer operon was present on a transposon, designated TnAO22, captured by introducing a broad-host-range IncP plasmid into Achromobacter sp. AO22 and subsequently transferring it to E. coli recipients. The transposition frequency of TnAO22 was 10-2 to 10-3 per target plasmid transferred. Analysis of TnAO22 sequence revealed it belonged to the Tn21 subgroup of the Tn3 superfamily of transposons, with the transposition module having >99% identity with Tn5051 of a Pseudomonas putida strain isolated from a water sample in New York. Conclusion TnAO22 is thus a new variant of Tn5051 of the Tn3 superfamily and the transposon and its associated mercury resistance system are among the few such systems reported in a soil bacterium. Achromobacter sp. AO22 can thus be exploited for applications such as in situ mercury bioremediation of contaminated sites, or the mobile unit and mer operon could be mobilized to other bacteria for similar purposes.

    2016-02-01

    Vitamin B12 deficiency has been associated with significant neurological pathology, especially peripheral neuropathy. This review aims to examine the existing evidence on the effectiveness of vitamin B12 supplementation for the treatment of diabetic peripheral neuropathy. A search of PubMed and the Cochrane Central Register of Controlled Trials for all relevant randomised controlled trials was conducted in December 2014. Any type of therapy using vitamin B12 or its coenzyme forms was assessed for efficacy and safety in diabetics with peripheral neuropathy. Changes in vibration perception thresholds, neuropathic symptoms and nerve conduction velocities, as well as the adverse effects of vitamin B12 therapy, were assessed. Four studies comprising 363 patients met the inclusion criteria. This review found no evidence that the use of oral vitamin B12 supplements is associated with improvement in the clinical symptoms of diabetic neuropathy. Furthermore, the majority of studies reported no improvement in the electrophysiological markers of nerve conduction. Copyright © Singapore Medical Association.

  1. Dietary fat intake, supplements, and weight loss

    Science.gov (United States)

    Dyck, D. J.

    2000-01-01

    Although there remains controversy regarding the role of macronutrient balance in the etiology of obesity, the consumption of high-fat diets appears to be strongly implicated in its development. Evidence that fat oxidation does not adjust rapidly to acute increases in dietary fat, as well as a decreased capacity to oxidize fat in the postprandial state in the obese, suggest that diets high in fat may lead to the accumulation of fat stores. Novel data is also presented suggesting that in rodents, high-fat diets may lead to the development of leptin resistance in skeletal muscle and subsequent accumulations of muscle triacylglycerol. Nevertheless, several current fad diets recommend drastically reduced carbohydrate intake, with a concurrent increase in fat content. Such recommendations are based on the underlying assumption that by reducing circulating insulin levels, lipolysis and lipid oxidation will be enhanced and fat storage reduced. Numerous supplements are purported to increase fat oxidation (carnitine, conjugated linoleic acid), increase metabolic rate (ephedrine, pyruvate), or inhibit hepatic lipogenesis (hydroxycitrate). All of these compounds are currently marketed in supplemental form to increase weight loss, but few have actually been shown to be effective in scientific studies. To date, there is little or no evidence supporting that carnitine or hydroxycitrate supplementation are of any value for weight loss in humans. Supplements such as pyruvate have been shown to be effective at high dosages, but there is little mechanistic information to explain its purported effect or data to indicate its effectiveness at lower dosages. Conjugated linoleic acid has been shown to stimulate fat utilization and decrease body fat content in mice but has not been tested in humans. The effects of ephedrine, in conjunction with methylxanthines and aspirin, in humans appears unequivocal but includes various cardiovascular side effects. None of these compounds have been

    Algae dietary supplements are marketed worldwide as natural health products. Although their proprieties have been claimed as beneficial to improve overall health, there have been several previous reports of contamination by cyanotoxins. These products generally contain non-toxic cyanobacteria, but the methods of cultivation in natural waters without appropriate quality controls allow contamination by toxin producer species present in the natural environment. In this study, we investigated the presence of total microcystins, seven individual microcystins (RR, YR, LR, LA, LY, LW, LF), anatoxin-a, dihydroanatoxin-a, epoxyanatoxin-a, cylindrospermopsin, saxitoxin, and β-methylamino-l-alanine in 18 different commercially available products containing Spirulina or Aphanizomenon flos-aquae . Total microcystins analysis was accomplished using a Lemieux oxidation and a chemical derivatization using dansyl chloride was needed for the simultaneous analysis of cylindrospermopsin, saxitoxin, and β-methylamino-l-alanine. Moreover, the use of laser diode thermal desorption (LDTD) and ultra-high performance liquid chromatography (UHPLC) both coupled to high resolution mass spectrometry (HRMS) enabled high performance detection and quantitation. Out of the 18 products analyzed, 8 contained some cyanotoxins at levels exceeding the tolerable daily intake values. The presence of cyanotoxins in these algal dietary supplements reinforces the need for a better quality control as well as consumer's awareness on the potential risks associated with the consumption of these supplements.

    At the present time, the abuse of all class of sport nutritional supplements (NS) has extended the people who go regularly to gymnasiums. Between these substances there are the Protein Powder Supplements (PPS). The purpose of this study is to examine the consumption of PPS in 415 individuals from Seville fitness centers. All individuals were evaluated with anthropometric measurements and completed a questionnaire previously reviewed, evaluating the validity of the content, application, structure and presentation. 28% of the individuals were using or used PPS. Of the total, 42.7% of male individuals compared to 3.2% of the females. The use of PPS was higher than what has been reported in previous studies about supplement use in fitness center, 28% vs 10-14% aprox. The SPP use is associated with sex, age, and time of sport practiced. More than a 25% of the total individuals that attend a gym use PPS. The total individuals that attend a gym and use PPS far exceed the RDA of protein for general population and/or athletes, being able to cause problems of health.

    Full Text Available Analysis of diabetic patients’ dietary habits indicate that there is an imbalance of selected vitamins and minerals. A nutrient supplement composition; intended for prophylactic administration, was developed to correct this imbalance. It was composed of dried eggs and yeast component (60%, vitamin В1 (0.02% and nicotinamide (0.04%, chromium chelate (0.02%, “selen-active” (0.02% and lecithin (39.9%. The dried eggs and yeast component was prepared by homogenization of lysozyme rich chicken eggs and yeast followed by storage and drying at a pre-defined temperature and to a set water content respectively. The nutritional supplement was incorporated at 5% concentration into a cooked sausage recipe. An assessment of the safety and efficacy of the prophylactic nutritional supplement was performed in an alloxan induced diabetic rat model. The developed composition, as a part of feedstuff, improved metabolic processes, increased antioxidant activity, reduced lipid peroxidation, decreased blood cholesterol, and improved the carbohydrate metabolism.

    Full Text Available Modern approaches to management of medical conditions are based on a holistic view, taking into account bidirectional connections between physical and mental health. The current pharmacologically focused model has so far provided modest benefits in addressing the burden of poor mental health. Convincing data suggest that diet quality and select nutrient-based supplements might influence a range of neurochemical modulatory activities, improving the management of mental disorders. Examples of these nutrient-based supplements include omega-3 fatty acids, S-adenosyl methionine, N-acetyl cysteine, zinc, B vitamins (including folic acid, and vitamin D. The traditional Mediterranean diet is considered to be the most beneficial diet in our region. Based on the results of preclinical studies, we are increasingly aware of the role of intestinal microbiota in the pathogenesis and potential treatment of mental disorders. Bidirectional signalling between the brain and the gut microbiome involving vagal neurocrine and endocrine signalling mechanisms influences mental and physical wellbeing. These findings suggest that using prebiotics, probiotics or in the strict sense psychobiotics, as well as incorporating fermented foods in the diet, could have a potential role in the management of mental disorders. As of now, we lack sufficient evidence to implement recommendations for dietary supplements in treatment guidelines, however, this might change in light of emerging data from contemporary research studies, at least for certain indications.

    Full Text Available Many national and international public health organisations recommend achieving nutrient adequacy through consumption of a wide variety of nutritious foods. Despite this, dietary supplement sales continue to increase. Understanding the characteristics of micronutrient supplement users and the relationship with diet quality can help develop effective public health interventions to reduce unnecessary consumption of vitamin and mineral supplements. Participants (n = 1306 were a convenience sample of students studying first year food and nutrition. Data was collected via a Food and Diet Questionnaire (FDQ and a Food Frequency Questionnaire (FFQ. Supplement users were defined as participants who indicated consuming any listed supplement as frequently as once a month or more. Diet quality was assessed using a Dietary Guideline Index (DGI score. Prevalence of supplement use was high in this study population with 56% of participants reporting supplement use; the most popular supplements consumed were multivitamins (28% and vitamin C (28%. A higher DGI score was significantly associated with an increased likelihood of supplement use (mean: 105 ± 18 vs. 109 ± 17, p = 0.001. Micronutrient supplement use was associated with a higher DGI score, suggesting that supplements are more likely to be used by those who are less likely to require them.

    It is legal tomarketmost naturally occurring substances as dietary supplements in the USA without manufacturers demonstrating they are safe or effective, and an endless variety of ingredients, from esoteric botanicals to unapproved pharmaceuticals, can be found in dietary supplements. Use of certain supplements can pose a risk, but since a robust reporting systemdoes not exist in the USA it is difficult to know which are problematic and the number of adverse events (AE) resulting from their use. Certain populations, includingmilitary personnel, aremore likely to use dietary supplements than the general population. Approximately 70% of military personnel take dietary supplements while about 50% of civilians do. Service members prefer supplements purported to enhance physical performance such as supposedly natural stimulants, protein and amino acids, and combination products. Since some of thesemay be problematic, Servicemembers are probably at higher risk of injury than the general population. Ten percent of military populations appear to be taking potentially risky supplements, and the US Department of Defense (DoD) has taken variousmeasures to protect uniformed personnel including education, policy changes, and restricting sales. Actions taken include launching Operation Supplement Safety (OPSS), introducing a High Risk Supplement list, educating health care professionals on reporting AE thatmight be associated with dietary supplements, recommending policy for reporting AE, and developing an online AE reporting system. OPSS is a DoD-wide effort to educate service members, leaders, health care providers, military families, and retirees on how to safely select supplements

    Bodybuilder-type workouts may affect heart rate variability (HRV), which has considerable potential to assess the role of autonomic nervous system (ANS). A scientifically designed approach is necessary for bodybuilders to achieve better results while protecting their health. In this study, we aimed to investigate HRV parameters in bodybuilders compared to healthy control subjects and effects of creatine supplementation. A total of 48 male participants (16 controls, 16 supplement (-), 16 supplement (+)) were evaluated in our study. Bodybuilders who were taking creatine supplementation were enrolled in supplement (+) group. HRV parameters were measured from 24-hour Holter recordings of all participants. When mean heart rates were compared with control group (71.5 ± 12.6 beats/min), statistically significant difference was revealed in supplement (-) group (61.8 ± 6.8 beats/min; P = 0.022) unlike supplement (+) group (69.63 ± 14.1 beats/min; P = 0.650). HRV analyses revealed significant parasympathetic shift in supplement (-) group. No significant difference was demonstrated on HRV parameters, except high frequency (P = 0.029) in supplement (+) group. Conclusively, elevated parasympathetic modulation, which is favorable cardiovascular outcome of exercise, was demonstrated in bodybuilders. However, our study also revealed that creatine supplementation attenuates this favorable effect in ANS by limiting elevation of parasympathetic modulation. Although the sympathetic slight shift is attributed to creatine supplementation, it cannot be discriminated from the effects of over training. © 2017 Wiley Periodicals, Inc.

    Sewage solids were collected as 'primary settled solids' and then dried and gamma-irradiated (using 60 Co or 177 Cs) to absorbed dosage of about one magarad to minimize viable parasites and pathogenic organisms. Nutrient composition and bioassays suggested prospective usage as supplemental feed for ruminants. In a large-scale experiment, beef cows grazing poor-quality rangeland forage during late gestation-early lactation were given either no supplemental feed or cottonseed meal or experimental supplement comprised of 62% sewage solids. Supplements were provided for 13 weeks until rangeland forage quality improved seasonably. Supplemental cottenseed meal for cows improved weaning weights of calves by about 11% over unsupplemented controls; whereas, supplement with 62% sewage solids improved calf weaning weights by about 7%. Hazards or risks to animals or to human health appear to be slight when sewage solids of this type are fed as supplemental feeds to cattle in production programs of this type. (Auth.)

  13. On some properties of ⊕-supplemented modules

    Full Text Available A module M is ⊕-supplemented if every submodule of M has a supplement which is a direct summand of M. In this paper, we show that a quotient of a ⊕-supplemented module is not in general ⊕-supplemented. We prove that over a commutative ring R, every finitely generated ⊕-supplemented R-module M having dual Goldie dimension less than or equal to three is a direct sum of local modules. It is also shown that a ring R is semisimple if and only if the class of ⊕-supplemented R-modules coincides with the class of injective R-modules. The structure of ⊕-supplemented modules over a commutative principal ideal ring is completely determined.

    In vitamin A deficient populations, the amount of vitamin A may be insufficient for maintenance of maternal health and levels in breast milk may be insufficient for breastfeeding infants' needs. To assess the effects of postpartum maternal vitamin A supplementation on maternal and infant health. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 July 2010), LILACS (1982 to July 2010), Web of Science (1945 to July 2010) and Biological Abstracts (1998 to July 2010). Randomised controlled trials evaluating the effects of postpartum maternal vitamin A supplementation. Two review authors assessed the studies independently. We included 12 trials at moderate risk of bias, enrolling 25,465 mother-baby pairs and comparing several postpartum doses (200,000-400,000 IU) of vitamin A or 7.8 mg daily beta-carotene, with placebo, iron or no supplement; or higher (400,000 IU) versus lower dose (200,000 IU). The majority of infants in all studies were at least partially breastfed for six months.Maternal: we observed no impact of vitamin A on maternal mortality (two trials of 9,126 women), morbidity (one trial of 50 women) or adverse effects (subset of 786 women in one trial). Vitamin A enhanced serum and breast milk retinol at three months in five trials, but these improvements were generally not sustained.Infant: we observed no significant differences for infant mortality RR 1.14 95% CI 0.84 to 1.57 (five trials (6,170 infants) or morbidity (three trials) except for fewer episodes of fever with vitamin A in one small trial. No significant differences in infant vitamin A status were seen with maternal vitamin A supplementation (five trials).No beneficial effects for maternal or infant health were associated with higher compared to lower doses of vitamin A in two trials. The lack of effect on maternal and infant mortality and morbidity, with exception of some improved infant morbidity in one small study, and the improvement in maternal vitamin A status

    Full Text Available O transtorno bipolar (TB é uma doença crônica, recorrente, presente em 1,5% da população, estando associada a altas taxas de mortalidade e prejuízos socioeconômicos. O lítio, a carbamazepina e o ácido valpróico são os estabilizadores de humor mais usados. Em tratamentos prolongados, como é o caso do TB, a má-adesão dos pacientes é uma das maiores dificuldades. Verifica-se que fatores ligados ao paciente, aos medicamentos e aos médicos possam ser responsáveis pela baixa adesão. A psicoeducação, a terapia cognitivo-comportamental e a terapia focada na família são estratégias propostas para o aumento da adesão.Bipolar disorder (BD is a chronic and recurrent illness that occurs in 1,5% of the population. This illness is associated with high rates of mortality and social/economic burden. Lithium, carbamazepine and valproic acid are the most used mood stabilizers. In long term treatments, as in BD, one of the main difficulties is the patient's adherence. It appears that factors associated to the patient, drug and the physician are responsible for the low adherence. The use of psycho-education, cognitive-behavioral therapy and focused family therapy have been put forward as a means to increase adherence.

    Full Text Available O município de São Joaquim, na região serrana de Santa Catarina, tem sido destacado pela imprensa escrita e televisiva nacional como a cidade mais fria do Brasil, ao longo dos últimos vinte anos. Em pesquisa realizada para tese de doutorado, identifiquei que muitas proprietárias de pousadas, as “pousadeiras” como elas mesmas se chamam, começaram abrigando turistas em dificuldades em dias de frio intenso, quando não há hotéis e pousadas suficientes na cidade. A partir disso, elas acreditaram ser possível transformar suas casas em pousadas, tendo diante de si um problema também compartilhado com os profissionais do turismo, a chamada sazonalidade dos turistas. Tal fato provoca dúvidas sobre a sustentação econômica das pousadas e inquietação aos profissionais quanto ao sucesso econômico do turismo. Nesse artigo, isso é analisado tendo como referência uma proposta de parceria recebida por meus interlocutores por parte da operadora de turismo CVC e da empresa de eventos da RBS, afiliada da Rede Globo em Santa Catarina. A discussão é em torno de questões a partir de uma antropologia da hospitalidade. A análise sugere que essa parceria ameaça uma ordem moral estabelecida com base em determinados valores de hospitalidade para com estranhos, principalmente o aquecimento perante o frio.

    This progress report broadly defines the scope of supplementation plans and activities in the Columbia Basin. It provides the foundation for more detailed analysis of supplementation in subsequent reports in this series. Topics included in this report are: definition of supplementation, project diversity, objectives and performance standards, uncertainties and theory. Since this is a progress report, the content is subject to modification with new information. The supplementation theory will continue to evolve throughout the duration of RASP and beyond. The other topics in this report are essentially complete and are not expected to change significantly. This is the first of a series of four reports which will summarize information contained in the larger, RASP progress and completion reports. Our goal is to make the findings of RASP more accessible by grouping related topics into smaller but complete narratives on important aspects of supplementation. We are planning to publish the following reports under the general title Supplementation in the Columbia River Basin: Part 1, Background, Description, Performance Measures, Uncertainty and Theory; Part 2, Theoretical Framework and Models; Part 3, Planning Guidelines; and Part 4, Regional Coordination of Research and Monitoring. Supplementation is expected to be a major contributor to the planned increase in salmon and steelhead production in the Columbia Basin. The Fish and Wildlife Program of the Northwest Power Planning Council (NPPC) uses three approaches to protect and enhance salmon and steelhead in the Columbia Basin: (1) enhance fish production; (2) improve passage in the mainstem rivers; and (3) revise harvest management to support the rebuilding of fish runs (NPPC 1987). The fish production segment calls for a three-part approach focused on natural production, hatchery production, and supplementation. Supplementation is planned to provide over half of the total production increases. The Regional Assessment
