    With the recent rise in the number of Tommy John surgeries, a proportionate rise in revisions is expected. However, much is unknown regarding the current revision rate of Tommy John surgery, return to play, and change in performance in Major League Baseball (MLB) pitchers. Publicly available databases were used to obtain a list of all MLB pitchers who underwent primary and revision Tommy John surgery. Pitching performance preoperatively and postoperatively for pitchers who returned to 1 or more MLB games after revision surgery was compared with controls matched for age and position. Since 1999, 235 MLB pitchers have undergone Tommy John surgeries; 31 pitchers (13.2%) underwent revision surgery, and 37% underwent revision within 3 years of the index procedure. Twenty-six revisions had more than 2 years of follow-up; 17 pitchers (65.4%) returned to pitch at least 1 major league game, whereas only 11 (42.3%) returned to pitch 10 or more games. Of those who returned to MLB competition, the average length of recovery was 20.76 months. Compared with controls matched for age and position, MLB pitchers undergoing revision surgery had a statistically shorter career after revision surgery (4.9 vs 2.6 seasons, P = .002), pitched fewer innings, and had fewer total pitches per season. The rate of revision Tommy John surgery is substantially higher than previously reported. For MLB pitchers, return to play after revision surgery is much lower than after primary reconstruction. The overall durability of MLB pitchers after revision ulnar collateral ligament reconstruction decreases significantly compared with controls matched for age and matched controls.

    2016-01-01

    Full Text Available The objective of this work was to evaluate the gas exchange, leaf temperature, yield and water use efficiency in 'Tommy Atkins' mango under irrigation deficit strategies. The experimental design was randomized block, with seven treatments with regulated deficit irrigation (RDI under micro - spray and five treatments with partial root - zone drying (PRD under drip irrigation. The treatments on RDI consisted of application of 100, 75 and 50% of ETc at the stages S1 (beginning of flowering to fruit set S2 (fruit development and S3 (fruit physiological maturation. The treatments on PRD consisted of application of 100, 80, 60 and 40% of ETc, in the same three stages, alternating the irrigation side every 15 days. The regulated deficit irrigation causes less negative interference in gas exchange than the partial root - zone drying, and the climate factors affect the gas exchange and leaf temperature of 'Tommy Atkins' mango more than the regulated deficit irrigation. The partial root - zone drying irrigation with 60 and 40% of ETc causes a decrease in the 'Tommy Atkins' mango yield. The regulated deficit irrigation up to 50% of ETc, applied at the fruit maturation stage, maintain the yield and water use efficiency.

    The effects of ionizing radiation at doses of 0.5 and 1.0 kGy were evaluated in mango cultivar Tommy Atkins when harvested at maturation stage showing yellow flesh and skin color more red than green, representing four degree of maturation at commercial scale. The fruits were stored for 21 days at 12 degree C and sensory evaluated after that period as its external appearance, internal appearance, acidic taste, sweet taste, mellow flavor, aroma, texture and succulence of the flesh, by a team of ten trained judges. Physic chemical analysis of the main characteristics of fruits quality were also performed in the pulp at the end of storage. The results of sensory analysis revealed that the doses used did not damaged the sensory characteristics of mango fruit and that they received a dose of 0.5 kGy showed higher acceptance for most sensory attributes evaluated. The physic chemical characteristics showed no significant differences between the doses, except the amount of ascorbic acid that decreased progressively with increasing doses. Application of this method is viable for mango cultivar Tommy Atkins when taken with a higher degree of maturity and was safe for the external market and sensory acceptable. (author)

    Full Text Available This study aimed to evaluate the fruit yield and the distribution of 'Tommy Atkins' mango root system under different irrigation regimes in the semiarid region of Bahia. The experimental design was completely randomized with five treatments and three replicates: 1 - Irrigation supplying 100% of ETc in phases I, II and III; 2 - Regulated deficit irrigation (RDI supplying 50% of ETc in phase I (beginning of flowering to early fruit growth; 3 - RDI supplying 50% ETc in phase II (start of expansion until the beginning of physiological maturity; 4 - RDI supplying 50% ETc in phase III (physiological mature fruits; 5 - No irrigation during all three phases. The regulated deficit irrigation supplying 50% of the ETc during phase I and II provided larger root length density of 'Tommy Atkins' mango. Regardless of management strategy, the roots were developed in all evaluated soil volume and the highest density is concentrated from 0.50 to 1.50 m distance from the trunk and in 0.20 to 0.90 m depth in the soil, that suggests this region to be the best place for fertilizer application as well for soil water sensor placement. The application of RDI during fruit set does not influence either root distribution or production. Root system and crop production is significantly reduced under no irrigation conditions.

    Several reports have focused on utilization of post-harvest residues of crops, while neglecting those residues produced by mango processing. These residues represent a waste of nutrients and a source of environmental contaminants. Such by-products could be valuable sources of dietary fiber (DF), antioxidant compounds, and single carbohydrates. The aim of this study was to evaluate some functional properties (FP), and the content of DF and polyphenols (PP) of the peel and coarse material obtained from residues during the industrial processing of Ataulfo and Tommy Atkins mangoes. The total dietary fiber (TDF) content was about 225 mg/g and 387 mg/g (dry weight) for the coarse material and the peel, respectively, from which soluble dietary fiber represented 23 and 42%, respectively. The main neutral sugar identified was rhamnose, especially in peels; the klason lignin (KL) content was 92 mg/g, which highlights the Ataulfo peel (Ataulfo-P) and the Tommy Atkins peel (Tommy Atkins-P). The extractable PP content in Ataulfo-P was higher than in Tommy-Atkins-P, and interesting data for non-extractable PP were obtained in the residues. FP as swelling, water holding, oil holding, and glucose absorption in the residues was studied, obtaining better functional properties when compared to cellulose fiber. The results show that mango industrial by-products, mainly from the Ataulfo-P variety, could be used as ingredients in food products because of their functional properties as well as their DF and PP content.

    Full Text Available A mangicultura no semiárido brasileiro destaca-se pelos altos rendimentos, pela qualidade do fruto produzido e pela possibilidade de produção durante todo o ano, devido a condições climáticas e tecnologias para o manejo do crescimento vegetativo e da floração, com uso da irrigação, podas e retardantes vegetais. O paclobutrazol aplicado ao solo é utilizado no manejo da produção da mangueira na maioria dos pomares. Entretanto, há a necessidade de identificar retardantes vegetais que possam ser aplicados via foliar, de forma a minimizar os resíduos no solo e evitar o uso de quantidades inadequadas ao longo dos anos. Assim, este trabalho teve como objetivo avaliar retardantes vegetais aplicados via foliar na inibição do crescimento vegetativo de mudas de mangueira 'Tommy Atkins'. Prohexadione-Ca, etil-trinexapac e cloreto de chlormequat, aplicados via foliar, na dose de 1g i.a. planta-1, regulam o crescimento de ramos vegetativos, mas apresentam tempo diferenciado de atividade nas mudas, sendo 20 dias para prohexadione-Ca, 30 dias para cloreto de chlormequat e 45 dias para etil-trinexapac, nas condições em que o experimento foi conduzido.The mango in the Brazilian semi-arid region stands out in the national scenario due to high yields and fruit quality, as well as to the possibility of all-year production due to climatic conditions and technologies which allow the management of plant growth and flowering through irrigation, pruning and use of plant growth regulators. Paclobutrazol applied to the soil is used for the production management of mangoes in most of the orchards. However, it is necessary to identify plant growth regulators which might be applied to the leaves, so as to minimize the risk of residues in the soil and to avoid inadequate application levels over several years. The present paper aimed at evaluating the effect of plant growth regulators applied to the leaves, regarding their efficiency for flowering management

    Full Text Available Procurou-se determinar os fatores da relação planta/ambiente que predispõem frutos da variedade de manga Tommy Atkins a apresentarem distúrbios fisiológicos. Para isso, foram analisados os posicionamentos dos frutos na planta, estádios de maturação e a relação vigor do ramo/fruto. As avaliações permitiram concluir que: a o posicionamento dos frutos na planta não tem influência alguma na ocorrência das desordens fisiológicas; b existe certa relação entre vigor dos ramos e a presença dos distúrbios nos frutos; c o percentual de ocorrência dos distúrbios fisiológicos é altamente influenciado pelo estádio de maturação do fruto à colheita, sendo que, é de pequena monta em frutos colhidos precocemente.Factors of the relation plant/environment which predispose mangoe fruits, var. Tommy Atkins, to physiological disorders were determined. Therefore, fruit location in the plant, the degree of ripeness and the relation of vigor between branch/fruit were analysed. The results allowed the following conclusions: a the fruit positioning in the plant has no influence on the occurence of physiological disorders; b there is a certain relation between vigor of the branch and the presence of disorders in the fruit; c the percentage of occurrence of physiological disorders is a function of the fruit ripeness degree at harvest time, being very small when the fruit is harvested early.

    Full Text Available Com o objetivo de avaliar o efeito do equilíbrio nutricional sobre a incidência de distúrbios fisiológicos em manga 'Tommy Atkins' cultivada no Vale do São Francisco, realizou-se um ensaio com frutos coletados no estádio de maturação fisiológica, classificados em frutos sem sintomas e com sintomas de distúrbio fisiológico. Os frutos das duas classes foram separados em casca, polpa e caroço, e levados para secagem em estufa a 65 °C. Este material foi submetido a mineralização para a determinação das concentrações de N, K, Ca, Mg e B. Antes da desidratação, uma parte da polpa foi separada para as determinações do teor de sólidos solúveis totais (SST e da acidez total titulável (ATT. Os resultados permitem concluir que, tanto as concentrações elevadas de Ca e Mg, como as baixas relações N/Ca e K/Ca, tanto na polpa quanto na casca, foram eficientes na prevenção de distúrbios fisiológicos nos frutos de mangueira; a concentração de nutrientes obtida na casca pode refletir melhor a condição da fisiopatia do que a concentração dos nutrientes na polpa dos frutos; os valores de SST e a relação SST/ATT determinada nos frutos com sintomas foram muito mais elevados do que nos frutos sem sintomas, devido a uma sobrematuração desordenada dos tecidos da polpa.With the objective of evaluating the effect of the nutritional balance on the incidence of physiological disorders in mango cv. Tommy Atkins, grown in São Francisco River Valley, a trial was carried out with fruits harvested at physiological ripening stage, classified as fruits without and with physiological disorder symptoms. From all of them, skin, flesh and pit were separated and dried in a stove at 65ºC. This material was mineralized in order to determine N, K, Ca, Mg and B contents. Before dehydration, part of the flesh was taken for estimation of the total soluble solids (TSS and total titrable acidity (TTA. The results allow to conclude that: high

    Pitching performance metrics, durability, and reinjury after Tommy John surgery in professional baseball players have not been well described. The purpose of this study was to determine the likelihood of return to professional competition, reinjury rate, and change in performance after Tommy John surgery in Major League Baseball pitchers. The hypothesis was that performance metrics and durability will decline after surgery. Cohort study; Level of evidence, 3. Publicly available records were accessed to generate a list of all Major League Baseball pitchers from 1999 to 2011 who had undergone ulnar collateral ligament reconstruction at any point in their careers; those with multiple reconstructive procedures were excluded. Return to active (≥1 game) or established (≥10 games) competition and/or placement on the disabled list was documented for each player. Among established players, pitching performance was compared pre- and postoperatively, as well as with age-matched control pitchers. Of 147 pitchers included, 80% returned to pitch in at least 1 Major League Baseball game. Only 67% of established pitchers returned to the same level of competition postoperatively, and 57% of established players returned to the disabled list because of injuries to the throwing arm. Finally, performance declined across several metrics after surgery compared with preinjury levels, such as earned run average, batting average against, walks plus hits per inning pitched, percentage of pitches thrown in the strike zone, innings pitched, percentage fastballs thrown, and average fastball velocity (P 50%), and performance declines across several major metrics after surgery. Patients undergoing Tommy John surgery should be counseled appropriately regarding the likelihood of return to preinjury levels of competition and performance. © 2014 The Author(s).

    Brazil is one of the largest mango producers and the third largest mango exporter worldwide. Irradiation treatment and its commercial feasibility have been studied in our country to make it possible to develop new markets and, consequently, to compete with the major exporters of mangoes, Mexico and India. This work was designed to compare irradiation treatment with the hot water dip treatment in mangoes cv. Tommy Atkins for export and to verify that the main attributes for acceptance, color and texture, as well as carbohydrate and organic acid contents, were maintained. In this study, the fruit was divided into groups: control, hot water dip-treated (46 °C for 90 min), and irradiation-treated at doses of 0.4 kGy and 1.0 kGy. The fruit was stored at low temperature (11 °C±2) for 14 days and then at room temperature (23 °C±2) until the end of the study. The results indicated that the fruit given a dose of 1.0 kGy remained in a less advanced stage of ripening (stage 3) throughout the storage period, but experienced a greater loss of texture in the beginning of the experiment. It was noted that only the control group had higher levels of citric acid and succinic acid on the last day of the experiment. There were no significant differences in the total sugar content between any treatment groups. Gamma radiation can be used as a quarantine treatment and does not interfere negatively with the quality attributes of mangoes.

    Full Text Available Com o objetivo de avaliar qual a melhor forma de preservar polpa de manga 'Tommy-Atkins', realizou-se este trabalho, visando a testar duas formas de conservação: polpa triturada e polpa processada em fatias, acondicionadas, respectivamente, em sacos plásticos de polietileno fechados hermeticamente e bandejas de poliestireno revestidas com filme plástico de PVC auto-aderente e esticável, com espessura de 12 mim, respectivamente, congeladas e posteriormente armazenadas a -18°C até a perda do valor comercial. Pelos resultados obtidos, pode-se observar que a polpa na forma triturada apresentou aspecto razoável até 20 semanas, enquanto, na forma de fatia, até 18 semanas, em decorrência da perda de firmeza; os teores de sólidos solúveis aumentaram e os de vitamina C decresceram em ambas as formas de preservação; a textura das fatias variou em função do tempo de armazenamento. No geral, verificou-se que a aparência, textura e o sabor foram afetados pelo tempo de armazenamento.With the objective to evaluate the best preservation methods of 'Tommy-Atkins' mango pulp, this work was idealizated to testify two processing methods: ground pulp and sliced pulp conditioned respectively, in polyethylene plastic bag and polystyrene trays covered with polyvinyl chloride film with 12 mum of thickness, frozen and stored at -18ºC. The results obtained demonstrated that ground pulp had reasonable aspects until 20 week while sliced pulp had reasonable aspects for 18 weeks, because it showed soft texture after this time; the content of soluble solids increased and the vitamin C decreased in both preservation forms; the pulp firmness in the sliced pulp varied with the storage time. In general the appearance, texture and flavor were affected by the storage time.

    Full Text Available The interaction between water deficit and the poor use of light radiation by plants can result in a reduction in gas exchange with a consequent reduction in growth and production. In the ‘Tommy Atkins’ mango, studies of this interaction are rare. Given the above, the aim was to evaluate ecophysiological variables in leaves of the ‘Tommy Atkins’ mango subjected to varying conditions of lighting and water regime in the canopy, at different times and under semi-arid conditions. The data were analysed in a completely randomised design, arranged in 3x3x4 split lots, with three replications. The first, second and third lots were represented by the water regime, position in the canopy and time of evaluation respectively. The variables for net carbon assimilation (A, stomatal conductance to water vapour (gs, transpiration (E, leaf temperature (Tf, air temperature (Ta and vapour pressure deficit (VPD were all measured in an open system, under artificial light and ambient CO2 concentrations, using the IRGA. The results showed that the interaction between water regime, position in the canopy and time of evaluation affect ecophysiology in the ‘Tommy Atkins’ mango. Leaves in the centre of the canopy (with less light show reduced capacity for production compared to the other leaves. Plants grown under a water regime of 50% display greater water use efficiency, especially during the most adverse environmental conditions (0900 to 1300. The efficient management of water conditions and leaf position in the canopy can positively affect gas exchange and consequently, growth and production. = A interação entre o déficit hídrico e o mau aproveitamento de radiação luminosa pelas plantas pode ocasionar redução nas trocas gasosas e, consequentemente, diminuir o seu crescimento e sua produção. Em mangueira ‘Tommy Atkins’, os estudos sobre essa interação são escassos. Diante do exposto, objetivou-se avaliar variáveis ecofisiológicas em

    Full Text Available Changes in amylase activity, starch and reducing and non-reducing sugars contents were monitored during ripening of mango fruits (Mangifera indica L.. The climateric raising in mango fruit is marked by an appreciable increase in the activity of amylase, reducing and non-reducing sugars contents and decrease in the starch content. The fruit affected with spongy tissue exhibited much lower amylase activity and reducing and non-reducing sugars, but exhibited much higher starch content during storage at 12 ± 2° C and 90 ± 5% RH for 28 days, when compared to healthy tissue of ?Tommy Atkins?. Whether this is caused due to adverse effects on certain enzyme activities during ripening is not clearly known. These dates showed that carbohydrate metabolism is an important feature during ripening of mango.

    Full Text Available O Brasil produz cerca de 140 milhões de toneladas de alimento por ano; entretanto, a fome ainda é um dos maiores problemas enfrentados por grande parte da sua população. O aproveitamento integral de alimentos é uma alternativa para suprir as necessidades nutricionais e contribuir para reduzir o lixo orgânico. Nesse sentido, cascas, talos, sementes e outras partes, tradicionalmente não utilizadas como alimentos, podem ser incorporadas na dieta alimentar. Estudos revelam que cascas de muitas hortifrutícolas possuem mais nutrientes que determinadas polpas, a parte tradicionalmente consumida. No entanto, o conhecimento sobre a concentração de metais pesados nessas frações também é importante, uma vez que podem provocar intoxicações alimentares, se consumidos, mesmo em concentrações reduzidas. O Brasil é o sétimo produtor mundial de manga e dentre as cultivares de importância comercial, a cv. Tommy Atkins é a mais plantada e exportada pelo Brasil. A pesquisa teve como objetivo determinar a composição centesimal e o perfil de macro e microminerais, inclusive, os elementos-traço, da casca e da polpa de manga cv. Tommy Atkins. A maior fração da composição centesimal da casca estudada foi a umidade, seguida dos carboidratos totais, com destaque para o teor de fibra alimentar total (FAT, que representou cerca 11% dessa quantidade. Já os teores de proteína e de cinzas apresentaram cerca de 2,5%, enquanto a fração lipídica foi inferior aos demais componentes. O perfil de minerais da casca revelou que as concentrações desses elementos foram superiores aos encontrados na polpa, exceto para zinco e ferro. As concentrações de metais pesados presentes na casca, em função das concentrações menores que 0,1 mg/100g, possibilitam a sua utilização na alimentação humana. A composição centesimal e perfil mineral da casca da manga demonstraram a sua importância nutricional e a possibilidade da utilização dessa parte, at

    Combination of citric acid dipping (5 g/L) and cassava starch coating (10 g/L), with and without glycerol (10 g/L), was studied to verify the effectiveness of these treatments to inhibit enzymatic browning, to reduce respiration rate, and to preserve quality parameters of "Tommy Atkins" fresh-cut mangoes during storage at 5 degrees C. Color characteristics (L and C), mechanical properties (stress at failure), weight loss, beta-carotene content, sensory acceptance, and microbial growth of fruits were evaluated during 15 d. The respiration rate of fruit subjected to the treatments was also analyzed. Nontreated fresh-cut mango was used as a control sample. Cassava starch edible coatings and citric acid dipping promoted a decrease in respiration rate of mango slices, with values up to 41% lower than the control fruit. This treatment also promoted better preservation of texture and color characteristics of mangoes and delayed carotenoid formation and browning reactions during storage. Moreover, the treated fruit showed great sensory acceptance by consumers throughout the whole storage period. However, the use of glycerol in the coating formulation was not efficient in the maintenance of quality parameters of fresh-cut mangoes, promoting a higher weight loss of samples, impairing fruit texture characteristics, increasing carotenogenesis, and favoring microbial growth during storage.

    Real-time profiling of mango ripening based on proton transfer reaction-time of flight-mass spectrometry (PTR-ToF-MS) of small molecular weight volatile organic compounds (VOCs), is demonstrated using headspace measurements of 'Tommy Atkins' mangoes. VOC metabolites produced during the ripening process were sampled directly, which enabled simultaneous and rapid detection of a wide range of compounds. Headspace measurements of 'Keitt' mangoes were also conducted for comparison. A principle component analysis of the results indicated that several mass channels were not only key to the ripening process but could also be used to distinguish between mango cultivars. The identities of 22 of these channels, tentatively speciated using contemporaneous GC-MS measurements of sorbent tubes, are rationalized through examination of the biochemical pathways that produce volatile flavour components. Results are discussed with relevance to the potential of headspace analysers and electronic noses in future fruit ripening and quality studies.

    Flavonol O- and xanthone C-glycosides were extracted from mango (Mangifera indica L. cv. "Tommy Atkins") peels and characterized by high-performance liquid chromatography-electrospray ionization mass spectrometry. Among the fourteen compounds analyzed, seven quercetin O-glycosides, one kaempferol O-glycoside, and four xanthone C-glycosides were found. On the basis of their fragmentation pattern, the latter were identified as mangiferin and isomangiferin and their respective galloyl derivatives. A flavonol hexoside with m/z 477 was tentatively identified as a rhamnetin glycoside, which to the best of our knowledge, has not yet been reported in mango peels. The results obtained in the present study confirm that peels originating from mango fruit processing are a promising source of phenolic compounds that might be recovered and used as natural antioxidants or functional food ingredients.

    This study assessed the efficacy of chitosan (CHI) and Mentha piperita L. essential oil (MPEO) alone or in combination to control the mycelial growth of five different Colletotrichum species, C. asianum, C. dianesei, C. fructicola, C. tropicale and C. karstii, identified as potential anthracnose-causing agents in mango (Mangifera indica L.). The efficacy of coatings of CHI and MPEO mixtures in controlling the development of anthracnose in mango cultivar Tommy Atkins was evaluated. CHI (2.5, 5, 7.5 and 10 mg/mL) and MPEO (0.3, 0.6, 1.25, 2.5 and 5 μL/mL) alone effectively inhibited mycelial growth of all tested Colletotrichum strains in synthetic media. Mixtures of CHI (5 or 7.5 mg/mL) and MPEO (0.3, 0.6 or 1.25 μL/mL) strongly inhibited mycelial growth and showed additive or synergistic inhibitory effects on the tested Colletotrichum strains based on the Abbott index. The application of coatings of CHI (5 or 7.5 mg/mL) and MPEO (0.6 or 1.25 μL/mL) mixtures that presented synergistic interactions decreased anthracnose lesion severity in mango artificially contaminated with either of the tested Colletotrichum strains over 15 days of storage at 25 °C. The anthracnose lesion severity in mango coated with the mixtures of CHI and MPEO was similar or lower than those observed in mango treated with the synthetic fungicides thiophanate-methyl (10 μg a.i./mL) and difenoconazole (0.5 μg a.i./mL). The application of coatings containing low doses of CHI and MPEO may be an effective alternative for controlling the postharvest development of anthracnose in mango cultivar Tommy Atkins.

    Full Text Available O Brasil produz cerca de 140 milhões de toneladas de alimento por ano; entretanto, a fome ainda é um dos maiores problemas enfrentados por grande parte da sua população. O aproveitamento integral de alimentos é uma alternativa para suprir as necessidades nutricionais e contribuir para reduzir o lixo orgânico. Nesse sentido, cascas, talos, sementes e outras partes, tradicionalmente não utilizadas como alimentos, podem ser incorporadas na dieta alimentar. Estudos revelam que cascas de muitas hortifrutícolas possuem mais nutrientes que determinadas polpas, a parte tradicionalmente consumida. No entanto, o conhecimento sobre a concentração de metais pesados nessas frações também é importante, uma vez que podem provocar intoxicações alimentares, se consumidos, mesmo em concentrações reduzidas. O Brasil é o sétimo produtor mundial de manga e dentre as cultivares de importância comercial, a cv. Tommy Atkins é a mais plantada e exportada pelo Brasil. A pesquisa teve como objetivo determinar a composição centesimal e o perfil de macro e microminerais, inclusive, os elementos-traço, da casca e da polpa de manga cv. Tommy Atkins. A maior fração da composição centesimal da casca estudada foi a umidade, seguida dos carboidratos totais, com destaque para o teor de fibra alimentar total (FAT, que representou cerca 11% dessa quantidade. Já os teores de proteína e de cinzas apresentaram cerca de 2,5%, enquanto a fração lipídica foi inferior aos demais componentes. O perfil de minerais da casca revelou que as concentrações desses elementos foram superiores aos encontrados na polpa, exceto para zinco e ferro. As concentrações de metais pesados presentes na casca, em função das concentrações menores que 0,1 mg/100g, possibilitam a sua utilização na alimentação humana. A composição centesimal e perfil mineral da casca da manga demonstraram a sua importância nutricional e a possibilidade da utilização dessa parte, at

    With the objective of evaluating the effect of ionising radiation on the main characteristics of post-harvest quality of mango, fruits of the variety Tommy Atkins have been irradiated with a Co-60 source at dose levels of 200, 400 and 600 Gy. The fruits were later stored in a refrigeration chamber at 11,5 deg C for fifteen days, to simulate transport conditions for an external market. Visual analysis of the fruits was carried out every five days. After that the fruits were kept stored under a temperature of 21 deg C for nine days, to simulate shelf-life conditions. During this period, visual, sensorial and physicochemical analyses were performed after three, six and nine days. Results of the visual analyses along the 24-day storage period have shown that irradiated fruits displayed greater firmness of the pulp and greener rind when compared with control. However, the presence of dark dots on the surface of the rind was detrimental to their overall appearance. Sensorial analyses have shown significant differences between the different applied doses, with a better index of acceptability for control fruits, certainly due to the dark dots on the irradiated mango. On the other hand, physicochemical analyses showed best results for irradiated fruits. (author)

    Full Text Available Abstract The mango has short postharvest shelf life which varies from 6 to 10 days at room temperature in its fresh form. The objective of this study was to evaluate the effect of usage of edible coatings based of cassava starch and chitosan on post-harvest shelf life of mango. Mangoes of Tommy Atkins variety were covered with nine different formulations of coatings in a factorial block experimental design. The fruits were stored at 25 °C and evaluated during storage for the weight loss (%, color parameters, sensory attributes evaluated by trained panel, the rate of CO2 production and microbiological contamination on the peels. Results analysed by linear regressions and ANOVA, demonstrated that chitosan showed significant effect on weight loss (% and on values of L*, a*, b*, chroma, ºhue, peel color, texture, aroma and time which correlated well for suitability of fruit consumption. The formulation containing 0.25% of chitosan and 0.5% of cassava starch showed most favorable results as it presented a post-harvest shelf life of 3 days more than the control fruits and lower rates of CO2 production, showing that this coating actually decreased the rate of the respiratory processes of mango, without compromising the proper ripening of the fruit.

    Mango (Mangifera indica L.) is a major tropical fruit that has not been exploited for fresh-cut or minimally processed products on a scale similar to apples, pineapples, or melons. The objective of this study was to investigate the effect of infrared (IR) treatment on total phenolics, carotenoids, ascorbic acid, and antioxidant properties of fresh-cut cubes from 'Tommy Atkin' mangoes. Mango cubes were IR treated (5, 10, 15 min) and evaluated at 4-d intervals during 16-d storage at 4 ± 1 °C. Total phenolics, carotenoids, and ascorbic acid content in fresh-cut control mango cubes were 43.33, 1.37, and 15.97 mg/100 g FW, respectively. IR treatments increased total phenolics (59.23 to 71.16 mg/100 g FW) and decreased ascorbic acid (12.14 to 15.38 mg/100 g, FW). Total carotenoids showed a mixed trend (1.13 to 1.66 mg/100 g, FW). The IR treatment showed a significant positive impact on antioxidant properties (μM TE/100 g, FW) of mango cubes, as assayed by ABTS (261.5 compared with 338.0 to 416.4), DPPH (270.5 compared with 289.4 to 360.5), and ORAC (6686 compared with 8450 to 12230). Total phenolics, carotenoids, ascorbic acid, and antioxidant capacity decreased over 16-d storage. However, IR treated samples had consistently higher ABTS, DPPH, and total phenolics during storage. It was demonstrated that IR treatment can be effectively used in improving antioxidant properties of fresh-cut mangoes with minimal effect on the visual appearance. Various methods/treatments are in use for extending the quality of fresh-cut fruits, including mild heat treatment. This study explored the application of infrared (IR) heat for processing fresh-cut mango cubes and evaluated its effect on vitamin C and antioxidant capacity during 16-d storage. This is the first study reporting on the use of IR heat in fresh-cut fruits. IR treatment was shown to be effective in retaining antioxidant properties of fresh-cut mango cubes with minimal effect on the visual appearance. © 2012 Institute

    Polyphenolics were extracted from peels, pulp and kernels of mango fruits (Mangifera indica L. cv. 'Tommy Atkins') and characterized by high-performance liquid chromatography/electrospray ionization mass spectrometry. In the peel 18 gallotannins and five benzophenone derivatives were detected which were tentatively identified as galloylated maclurin and iriflophenone glucosides. Twenty-one and eight gallotannins were found in the kernels and pulp, respectively, whereas no evidence for the presence of benzophenone derivatives was obtained. Gallotannins quantified by the rhodanine assay amounted to 1.4 mg/g dm in the peels (expressed as gallic acid), while only small amounts (0.2 mg/g dm) were found in the pulp. In contrast, mango kernels contained 15.5 mg/g dm and thus proved to be a rich source of gallotannins. Copyright 2004 John Wiley & Sons, Ltd.

    Full Text Available No processamento industrial da manga, os subprodutos, caroço e casca são, normalmente, descartados sem o devido aproveitamento. O objetivo deste trabalho foi investigar as características físico-químicas e funcionais dos amidos nativo e acidificado do caroço (amêndoa de manga, da variedade Tommy Atkins, pesquisando uma nova fonte de amido e formas de melhorá-la e contribuir para a utilização de resíduos da indústria alimentícia. As amêndoas foram retiradas manualmente dos caroços de manga e procedeu-se a extração do amido. O amido nativo foi acidificado, sendo o agente promotor da modificação o ácido clorídrico. Verificou-se a composição química do amido nativo. Determinaram-se também as propriedades funcionais e de pasta do amido nativo e do acidificado. Para a composição centesimal, o amido nativo apresentou 71,56% de amido, 7,30% de lipídeos e 5,6% de proteínas. Os amidos nativo e acidificado demonstraram baixa resistência à elevação da temperatura, com intumescimento máximo a 75 oC, sendo seus valores 9,395 e 6,861 g/g, respectivamente. A solubilidade mostrou-se crescente, à medida que houve elevação da temperatura, sendo seu valor máximo 48,03% para o amido acidificado. O amido nativo expôs maior capacidade de absorção de água, óleo e claridade da pasta. O referido amido ainda apresentou maior pico de viscosidade, viscosidade mínima, quebra de viscosidade, viscosidade final, retrogradação e temperatura de pasta do que os do amido acidificado. O amido nativo pode ser indicado para compor sopas desidratadas e produtos cárneos, enquanto o acidificado pode ser usado em alimentos congelados e refrigerados e na indústria de balas.

    Brazil is a great producer of tropical fruits including mangoes. Among several purposes gamma radiation can be applied as phytosanitary treatment. This is well studied in scientific papers and more recently demonstrated through commercial advances like bilateral protocols established between India and USA. The whole experiment evolved two parts where each of them used fruits from different maturity stages (stages 2 and 3). This experiment was carried out with around 300 fruits in each part of the study. The main objective was to get the experience close to commercial conditions. The irradiation was realized in Multipurpose Cobalt-60 source belonging to IPEN-CNEN/SP (developed in house by own technology). The absorbed doses were 0.2, 0.5 and 0.75 kGy. After irradiation all fruits were kept at 12 °C in acclimatized chamber during 14 days. After this period the fruits were brought to environmental conditions (25 °C) for around 14 more days of duration. These conditions were established to simulate the exportation conditions from Brazil to distant countries. Physical-chemical analysis (pH, titrable acidity, total soluble solids (°Brix) and texture) as well as visual observation (mass loss, rotting, internal and skin color) were evaluated. The results from this experiment could demonstrate that the characteristics of the mangoes are more dependent on time and temperature storage rather than irradiation.

    Accumulation of beta-carotene and trans-cis isomerization of ripening mango mesocarp were investigated as to concomitant ultrastructural changes. Proceeding postharvest ripening was shown by relevant starch degradation, tissue softening, and a rising sugar/acid ratio, resulting in a linear decrease (R (2) = 0.89) of a ripening index (RPI(KS)) with increasing ripening time. A modest accumulation of all-trans-beta-carotene and its cis isomers resulted in a slight pigmentation of the mango chromoplasts, because ambient temperatures of 18.2-19.5 degrees C provided suboptimal ripening conditions, affecting color development and beta-carotene biosynthesis. The ultrastructures of chromoplasts from mango mesocarp and carrot roots were comparatively studied by means of light and transmission electron microscopy. Irrespective of the ripening stage, mango chromoplasts showed numerous plastoglobuli varying in size and electron density. They comprised the main part of carotenoids, thus supporting the partial solubilization of the pigments in lipid droplets. However, because different pigment-carrying tubular membrane structures were also observed, mango chromoplasts were assigned to the globular and reticulotubular types, whereas the crystalline type was confirmed for carrot chromoplasts. The large portions of naturally occurring cis-beta-carotene in mango fruits contrasted with the predominance of the all-trans isomer characteristic of carrots, indicating that the nature of the structure where carotenoids are deposited and the physical state of the pigments are crucial for the stability of the all-trans configuration.

    Medial ulnar collateral ligament (UCL) reconstruction is a common procedure performed on Major League Baseball (MLB) pitchers with symptomatic UCL insufficiency, frequently due to overuse. Warm weather climates afford youth pitchers the opportunity to throw year-round, potentially placing them at risk for overuse elbow injuries. To determine whether the proportion of MLB pitchers who underwent medial UCL reconstruction and who pitched competitive youth baseball in warm weather areas is higher than those from cold weather areas. The hypothesis was that MLB pitchers from warm weather areas were more likely to undergo UCL reconstruction than pitchers from cold weather areas. Descriptive epidemiological study. All MLB pitchers with symptomatic UCL deficiency who underwent UCL reconstruction as of June 1, 2014, were evaluated. The state/country where they played high school baseball was identified from online reference websites. Warm and cold weather areas were defined by latitude distance from the equator and mean annual temperatures. A chi-square test was used to compare the proportion of MLB pitchers from warm versus cold weather areas who underwent UCL reconstruction. The study was 99.6% powered to detect a 100% effect size (eg, 1% vs 2%) and 71.4% powered to detect a 50% effect size (eg, 1% vs 1.5%) with setting α = .05. A total of 247 pitchers were identified who had undergone UCL reconstruction; 139 (56.3%) pitched high school baseball in warm weather areas, 108 (43.7%) pitched in cold weather areas. A significantly higher proportion of pitchers who underwent UCL reconstruction (2.2% [95% CI, 1.9%-2.6%]) were from warm weather areas compared with cold weather areas (0.94% [95% CI, 0.78%-1.1%]) (P baseball in warm weather climates have undergone medial UCL reconstruction more frequently and earlier in their MLB careers than pitchers who played in cold weather areas.

    Medial ulnar collateral ligament (UCL) reconstruction is a common procedure performed on Major League Baseball (MLB) pitchers in the United States. To determine (1) the rate of return to pitching (RTP) in the MLB after UCL reconstruction, (2) the RTP rate in either the MLB and minor league combined, (3) performance after RTP, and (4) the difference in the RTP rate and performance between pitchers who underwent UCL reconstruction and matched controls without UCL injuries. Cohort study; Level of evidence, 3. Major League Baseball pitchers with symptomatic medial UCL deficiency who underwent UCL reconstruction were evaluated. All player, elbow, and surgical demographic data were analyzed. Controls matched by age, body mass index, position, handedness, and MLB experience and performance were selected from the MLB during the same years as those undergoing UCL reconstruction. An "index year" was designated for controls, analogous to the UCL reconstruction year in cases. Return to pitching and performance measures in the MLB were compared between cases and controls. Student t tests were performed for analysis of within-group and between-group variables, respectively. A total of 179 pitchers with UCL tears who underwent reconstruction met the inclusion criteria and were analyzed. Of these, 148 pitchers (83%) were able to RTP in the MLB, and 174 pitchers were able to RTP in the MLB and minor league combined (97.2%), while only 5 pitchers (2.8%) were never able to RTP in either the MLB or minor league. Pitchers returned to the MLB at a mean 20.5 ± 9.72 months after UCL reconstruction. The length of career in the MLB after UCL reconstruction was 3.9 ± 2.84 years, although 56 of these patients were still currently actively pitching in the MLB at the start of the 2013 season. The revision rate was 3.9%. In the year before UCL reconstruction, pitching performance declined significantly in the cases versus controls in the number of innings pitched, games played, and wins and the winning percentage (P baseball after UCL reconstruction. Performance declined before surgery and improved after surgery. When compared with demographic-matched controls, patients who underwent UCL reconstruction had better results in multiple performance measures. Reconstruction of the UCL allows for a predictable and successful return to the MLB.

Pelo contraste apresentado na aparência externa dos frutos, a aplicação de cloreto de cálcio a 4% mostrou melhores resultados, porém sem garantir a qualidade final exigida para a exportação dos frutos. A aplicação de cloreto de cálcio não se mostrou efetiva no aumento do período de conservação dos frutos.The aim of this work was to study the effects of the application of calcium chloride associated with hydrothermal treatment on post-harvest preservation of mango fruit (Mangifera indica L.. The Ca absorption by mango peel and flesh was investigated using the same conditions usually employed for the fruit exportation to the american market. It was verified that the association of heat treatment to Ca application was viable. There was a positive correlation between the amount of Ca applied and the amount of this element presented in the peel, although low penetration toward the flesh was observed. It was demonstrated that Ca reduces anthracnose symptoms. It was also verified, by observing the external appearance of the fruits, that the best results were obtained when 4% of calcium chloride was used, although such concentration did not guarantee the required quality for the fruit exportation. The calcium chloride application was not effective to increase the shelf-life of the fruits.

    Mango processing produces significant amount of waste (peels and kernels) that can be utilized for the production of value-added ingredients for various food applications. Mango peel and kernel were dried using different techniques, such as freeze drying, hot air, vacuum and infrared. Freeze dried mango waste had higher antioxidant properties than those from other techniques. The ORAC values of peel and kernel varied from 418-776 and 1547-1819 μmol TE/g db. The solubility of freeze dried peel and kernel powder was the highest. The water and oil absorption index of mango waste powders ranged between 1.83-6.05 and 1.66-3.10, respectively. Freeze dried powders had the lowest bulk density values among different techniques tried. The cabinet dried waste powders can be potentially used in food products to enhance their nutritional and antioxidant properties. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Empirical evidence has suggested a connection between youth pitch counts and subsequent elbow injury. For players within the Little League World Series (LLWS), detailed historical player data are available. Some of these players progress to both professional play and require an ulnar collateral ligament reconstruction (UCLR). To determine the percentage of LLWS pitchers who proceed to play professional (major or minor league) baseball, the rate of UCLR in former LLWS pitchers who played professional baseball, and the risk to those who exceeded current pitch count recommendations while playing in the LLWS. Cohort study; Level of evidence, 3. All LLWS pitchers from 2001 through 2009 from all teams and countries were identified, and all performance data were extracted. A professional (major and minor league) baseball database was then searched to determine whether each former LLWS pitcher played professional baseball. These professional players were then searched for using publicly available databases to determine whether they underwent UCLR. Overall, 638 adolescents pitched in the LLWS between 2001 and 2009; 62 (10%) progressed to professional play. Of the 56 minor league players, 25 (45%) pitched. Of the 6 Major League Baseball players, 3 (50%) pitched. Three former LLWS pitchers (5%) who played professionally underwent UCLR. In former LLWS pitchers who exceeded pitch counts and played professionally, 50% (2/4) required UCLR, while only 1.7% (1/58) of those who did not exceed pitch count recommendations required UCLR (P = .009). Similarly, among former LLWS pitchers who subsequently played professionally, 23.1% of those who played as a pitcher required UCLR while 0% of those who also played other positions required UCLR (P = .008). Progression from LLWS pitching to professional baseball is uncommon. Among youth players, both diversification (playing other positions besides pitcher) as well as following current pitch limit regulations may protect against UCLR.

    Digital breast tomosynthesis (DBT) is a three-dimensional mammography technique with the potential to improve accuracy by improving differentiation between malignant and non-malignant lesions. The objectives of the study were to compare the diagnostic accuracy of DBT in conjunction with two-dimensional (2D) mammography or synthetic 2D mammography, against standard 2D mammography and to determine if DBT improves the accuracy of detection of different types of lesions. Women (aged 47-73 years) recalled for further assessment after routine breast screening and women (aged 40-49 years) with moderate/high of risk of developing breast cancer attending annual mammography screening were recruited after giving written informed consent. All participants underwent a two-view 2D mammography of both breasts and two-view DBT imaging. Image-processing software generated a synthetic 2D mammogram from the DBT data sets. In an independent blinded retrospective study, readers reviewed (1) 2D or (2) 2D + DBT or (3) synthetic 2D + DBT images for each case without access to original screening mammograms or prior examinations. Sensitivities and specificities were calculated for each reading arm and by subgroup analyses. Data were available for 7060 subjects comprising 6020 (1158 cancers) assessment cases and 1040 (two cancers) family history screening cases. Overall sensitivity was 87% [95% confidence interval (CI) 85% to 89%] for 2D only, 89% (95% CI 87% to 91%) for 2D + DBT and 88% (95% CI 86% to 90%) for synthetic 2D + DBT. The difference in sensitivity between 2D and 2D + DBT was of borderline significance (p = 0.07) and for synthetic 2D + DBT there was no significant difference (p = 0.6). Specificity was 58% (95% CI 56% to 60%) for 2D, 69% (95% CI 67% to 71%) for 2D + DBT and 71% (95% CI 69% to 73%) for synthetic 2D + DBT. Specificity was significantly higher in both DBT reading arms for all subgroups of age, density and dominant radiological feature (p breast density 50% or more, sensitivities were 93% versus 86% (p = 0.03); for grade 2 invasive tumours, sensitivities were 91% versus 87% (p = 0.01); where the dominant radiological feature was a mass, sensitivities were 92% and 89% (p = 0.04) For synthetic 2D + DBT, there was significantly (p = 0.006) higher sensitivity than 2D alone in invasive cancers of size 11-20 mm, with a sensitivity of 91%. The specificity of DBT and 2D was better than 2D alone but there was only marginal improvement in sensitivity. The performance of synthetic 2D appeared to be comparable to standard 2D. If these results were observed with screening cases, DBT and 2D mammography could benefit to the screening programme by reducing the number of women recalled unnecessarily, especially if a synthetic 2D mammogram were used to minimise radiation exposure. Further research is required into the feasibility of implementing DBT in a screening setting, prognostic modelling on outcomes and mortality, and comparison of 2D and synthetic 2D for different lesion types. Current Controlled Trials ISRCTN73467396. This project was funded by the NIHR Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 19, No. 4.

    The gold deposits in the western sector of the Central Spanish System can be grouped in: (1) gold quartz veins type (El Chivote, La Pedrera), (2) paleoplacers: gold nuggets in tertiary alluvial deposits (Las Cavenes, Sierro de Coria), (3) quaternary placers (Rio Erjas), (4) gold nuggets in a regolith developed on the Schist and Graywacke Complex (CEG) (Casillas de Coria). The morphological study of gold nuggets will provide physical, chemical, bacteriological and climatic characteristics. Mining works are located on these deposits from roman time to the present day.

    2015-02-01

    Full Text Available Saul Bellow, a distinctive prominent writer in American literature, is frequently concerned with the themes of Jewish culture, and alienation. In Bellow’s novel Seize the Day, Tommy Adler “the maladroit, suffering middle-aged hero of the book, is the pathetic heir in post-war fiction to the failure of the American Dream” (Richmond 15. Tommy abandons his family and endeavors to emulate his father. However, his father’s perfectionism and preference for avoidance of his son lead to the protagonist’s physical and psychological alienation. Furthermore, the resemblance of their lifestyles and attitudes indicates that their consciousness, sub-conscious, and psychologies follow the same routine. This study will therefore argue the novel’s psychoanalytic characteristics. Keywords: Mind Structure, Personality, Psychoanalysis, Saul Bellow, Seize the Day, Tommy Adler, Wilhelm Adler

    En el cultivo de mango se evaluó el efecto de 'Arauca' (genotipo débil e 'Hilacha' (genotipo vigoroso –utilizados alternadamente como portainjerto o injerto intermedio– sobre la calidad de fructificación de las variedades Irwin, Tommy Atkins y Davis-Haden, en un huerto de 21 años en el departamento del Tolima (Colombia. Los parámetros evaluados de calidad de fruta fueron: diámetro y longitud del fruto, firmeza, pH, peso fresco, sólidos solubles totales (SST, acidez total titulable (ATT y relación SST/ATT. Mientras que las variedades mostraron diferencias estadísticas en todos los parámetros de calidad de fruta que fueron evaluados, los portainjertos no produjeron diferencia alguna sobre estos parámetros. Las variables diámetro del fruto, firmeza, pH y acidez titulable fueron influenciadas por el interinjerto, mientras que el peso fresco, la longitud del fruto, los sólidos solubles totales y la relación SST/ATT permanecieron inalterados. Hubo diferencias significativas entre las combinaciones evaluadas (variedad/interinjerto/portainjerto para todos los parámetros evaluados, con excepción de la firmeza. Por ejemplo, las combinaciones Tommy Atkins/Hilacha/ Arauca y Tommy Atkins/Arauca/Hilacha presentaron valores cercanos de peso de fruto. Otro tanto sucedió al comparar las combinaciones Tommy Atkins/Hilacha y Tommy Atkins/Hilacha/ Arauca, para este mismo parámetro. Esto sugiere que el uso de 'Arauca' como portainjerto o como interinjerto, le confiere mayor peso del fruto a la variedad 'Tommy Atkins' , a pesar de que 'Arauca' es un portainjerto menos vigoroso que 'Hilacha'.

Eighteen compounds were present in Pica pulp (ppu), 13 in Pica peel (ppe) 11 in Tommy Atkins pulp (tpu) and 12 in Tommy Atkins peel (tpe). Three procyanidin dimers (peaks 6, 9 and 10), seven acid derivatives (peaks 1-4, 11, 20 and 21) and four xanthones were identified, mainly mangiferin (peak 12) and mangiferin gallate, (peak 7), which were present in both peel and pulp of the two studied species from northern Chile. Homomangiferin (peak 13) was also present in both fruit pulps and dimethylmangiferin (peak 14) was present only in Tommy pulp. Pica fruits showed better antioxidant capacities and higher polyphenolic content (73.76/32.23 µg/mL in the DPPH assay and 32.49/72.01 mg GAE/100 g fresh material in the TPC assay, for edible pulp and peel, respectively) than Tommy Atkins fruits (127.22/46.39 µg/mL in the DPPH assay and 25.03/72.01 mg GAE/100 g fresh material in the TPC assay for pulp and peel, respectively). The peel of Pica mangoes showed also the highest content of phenolics (66.02 mg/100 g FW) measured by HPLC-PDA. The HPLC generated fingerprint can be used to authenticate Pica mango fruits and Pica mango food products.

  13. Obituary: Thomas Gold, 1920-2004

    2004-12-01

    Thomas "Tommy" Gold died of heart disease at Cayuga Medical Center, Ithaca NY on 22 June 2004 at the age of 84. He will be remembered as one of the most interesting, dynamic and influential scientists of his generation. Tommy's paradigm-changing ideas in astronomy and planetary science, while original and bold, were also highly controversial. With his radical work on the origin of natural gas and petroleum, the controversy is likely to continue. Tommy was born in Vienna, Austria on 22 May 1920, moving with his family to Berlin at age 10 and then, after the rise of Hitler in 1933, to England. His parents were Josephine (nee Martin) and Maximillian Gold, a successful steel magnate. Tommy was educated at Zuoz College in Switzerland where he became an expert skier and developed an athletic prowess that he maintained throughout his life, winning a NASTAR gold medal for skiing at the age of 65. He studied Mechanical Sciences at Trinity College, Cambridge, but much to his disgust his education was interrupted because of internment by the British as a suspected enemy alien. That unfortunate period (I remember him saying to me "Can you believe the stupidity, interring people like me who had fled from Nazi Germany?") had one good outcome: on his first night in camp he met Hermann Bondi who had an important influence on his early development as a scientist. They were both born in Vienna, their parents knew each other, and they were fellow students at Trinity, but this was their first meeting. On release, he went immediately into top-secret radar research for the British Admiralty, working as a team with Bondi and Fred Hoyle in a farm cottage in Dunsfold, Surrey. Tommy's first published research, which was a Nature paper with R.J. Pumphrey in 1947, was not in astronomy but physiology. He applied his engineer's understanding of positive feedback to develop and test a resonance model for how the human ear determines pitch. His conclusion that pitch discrimination occurs

    Full Text Available A manga é uma fruta tropical muito popular em virtude das suas características exóticas e do seu valor nutritivo, sendo bastante apreciada na culinária e na alimentação da população brasileira. Este trabalho teve como objetivo analisar o comportamento higroscópico dos pós de manga das variedades Rosa e Tommy Atkins através de isotermas de adsorção, e as características físico-químicas e minerais tanto destes pós quanto das frutas na sua forma in natura. A partir dos resultados obtidos das análises físico-químicas e minerais para as amostras in natura e em pó, observa-se que as variedades Rosa e Tommy Atkins são estatisticamente semelhantes entre si na maioria dos parâmetros analisados. No entanto, observa-se que a variedade Rosa apresentou uma melhor qualidade nutricional que a variedade Tommy Atkins, notadamente no que se refere ao teor de vitamina C e carotenóides. Para o ajuste das isotermas de adsorção, os modelos de GAB e de Oswin se ajustaram satisfatoriamente aos dados experimentais dos pós de manga, exceto para a variedade Rosa. Também foi detectado que em ambientes com atividade de água elevada (a partir de 0,70 os pós das variedades Rosa e Tommy Atkins apresentam um comportamento mais higroscópico.

    The percentage of infested mango fruits of five selected mango varieties was evaluated during three years under field conditions. Three varieties with field resistance to fruit flies had less then 10% of fruits infested. Tommy Atkins, the susceptible commercial check, had 42,9% and the susceptible check had 98.9 % of infested fruits. The three field resistant varieties plus the susceptible commercial check, Tommy Atkins, were further tested in laboratory, under caged conditions, with artificial infestation of Anastrepha obliqua. The attempts of oviposition and the number of pupae developed from each fruit were evaluated. Under caged conditions, the cultivar Alfa maintained its field resistance and Espada Stahl and IAC 111 lost the field resistance and were as susceptible as Tommy Atkins. The attempts of oviposition were positively and highly correlated with the number of pupae developed in the fruits. Non preference for oviposition was confirmed as the main mechanism of resistance of mango fruits to fruit flies. In the absence of a more susceptible variety (no choice test) the cultivar Alfa has kept the resistance (author)

    Full Text Available After months of paralysis from injuries sustained in an automobile accident, W. Thomas Edmondson died in Seattle during January. Known as "Tommy" to one and all, in keeping with his nickname he retained a youthful and alert mind until the end. Tommy Edmondson will remain forever linked with the field of limnology that he loved. It is easy to recount his growth and accomplishments in science, starting from his first glimpse of a rotifer through the microscope he received as a gift at the age of 12. Those fortunate to have visited with him in his Seattle office can recall fondly the sight of a desk and chair piled high with "study graphs" and various works in progress which he would graciously set aside in welcome and eager interest for the visitor. But by his own reckoning, Tommy declared that there was a moment in time that was transformational in spirit and mind. That was the period in 1959 and 1960 during which he took sabbatical leave at the great limnological centers in Windermere, Uppsala, and Pallanza. Thirty five years later, he recalled the events with earnest delight, but his fondest memories were reserved for the town on the shore of Lago Maggiore. "We learned how to live in Pallanza," was his assessment of the time.

  7. Jasmonic acid induces resistance to economically important insect pests in winter wheat.

    2010-05-01

    Insect damage induces chemical changes in plants, and frequently these changes are part of a defensive response to the insect injury. Induced resistance was activated in winter wheat using a foliar application of synthetic jasmonic acid. Field trials were conducted to observe effects of jasmonic acid application on some wheat insects. Two wheat cultivars (Cubus and Tommi) were sprayed twice at growth stages (GS) 41 and 59 with two concentrations of jasmonic acid, along with control plots that were sprayed with water. There was a significant difference in the number of thrips and wheat blossom midges (WBM) among treatments in both cultivars. Plants in control plots had higher numbers of thrips and midges than in treated plots. There were higher numbers of thrips in the Tommi cultivar than in the Cubus cultivar, while the latter had higher numbers of WBM larvae than the Tommi cultivar. There was a positive correlation between WBM numbers and infested kernels in both cultivars. This study also indicated that jasmonic acid enhances the wheat yield in sprayed plots compared with control plots. The results indicate that jasmonic acid induced pest resistance in wheat plants and may act as a resistance mechanism of wheat against insect herbivores.

  8. Self-directed learning: implications and limitations for undergraduate nursing education.

    Self-directed learning (SDL) is an educational concept that has received increasing attention in recent years, particularly in the context of higher education. Whilst the benefits of SDL have been espoused by a number of adult education theorists (Brookfield, S., 1986. Understanding and Facilitating Adult Learning. Jossey-Bass, San Francisco; Houle, C., 1984. Patterns of Learning: New Perspectives on Life-Span Education. Jossey-Bass, San Francisco; Knowles, M., 1998. The Adult Leaner: A Neglected Species, fifth ed., Gulf, Houston; Tough, A., 1979. The Adults Learning Project: A Fresh Approach to Theory and Practice in Adult Learning. Ontario Institute for Studies in Education, Toronto), its introduction into curricula has not always been successful (Nolan, J., Nolan, M., 1997a. Self-directed and student-centred learning in nurse education: 1. British Journal of Nursing 6 (1), 51-55; Nolan, J., Nolan, M., 1997b. Self-directed and student-centred learning in nurse education: 2. British Journal of Nursing 6 (2), 103-107; Slevin, O., Lavery, M., 1991. Self-directed learning and student supervision. Nurse Education Today 11, 368-377). The indiscriminate application of SDL principles and poorly prepared teachers and/or students has at times meant that the introduction of SDL has been resented rather than welcomed (Iwasiw, C., 1987. The role of the teacher in self-directed learning. Nurse Education Today 7, 222-227; Turunen, H., Taskinen, H., Voutilainen, U., Tossavainen, K., Sinkkonen, S., 1997. Nursing and social work students' initial orientation towards their studies. Nurse Education Today 17, 67-71). This paper clarifies and explores these issues by: (a) examining the origins of SDL; (b) discussing the relevance of self-directed learning to Knowles' theory of adult learning and contemporary educational practices such as enquiry based learning and problem based learning; and (c) highlighting the implications and limitations of SDL with regard to adult education in

  9. Describing Quality and Sensory Attributes of 3 Mango (Mangifera indica L.) Cultivars at 3 Ripeness Stages Based on Firmness.

    To determine the ideal ripening stage for consumption of the mango cultivars, "Ataulfo," "Haden," and "Tommy Atkins"; fruits at 3 flesh firmness levels (ripeness stages) were evaluated by a trained panel using descriptive analysis after instrumental measurements were made. After harvest, all fruits were ripened to allow softening and quality and sensory attribute changes. Ripening changes during softening of Ataulfo mangos were expressed by a characteristic increase in the perception of "tropical fruit" and "peach" aromas, an increase in "juiciness," "sweetness," and "tropical fruit" flavor, while "fibrousness," "chewiness," and "sourness" decreased. Similar desirable sensory changes were also detected during softening of Haden mangos; an increase in tropical fruit and peach aromas, sweetness and tropical fruit flavor, and a decrease in chewiness, sourness, and bitterness. Softening of Tommy Atkins mangos was followed by reduced chewiness and sourness and increased peach aroma. Softening of all cultivars was followed by decreased sourness and titratable acidity (TA) and increased soluble solids concentration (SSC) and SSC:TA ratio. The results indicate that mango ripening leads to increased expression of sensory attributes such as tropical fruit and peach aromas, tropical flavor, and sweetness that have been related to improved eating quality and these final changes in sensory quality attributes are specific for each cultivar. For example, Ataulfo and Haden mangos had greater improvement in quality and sensory attributes related to fruit eating quality during ripening-softening than Tommy Atkins. In our consumer test, these quality-sensory attributes expressed during ripening that were perceived by the trained panel were also validated, supporting the need for a controlled ripening protocol in mangos. © 2015 Institute of Food Technologists®

    Full Text Available This study evaluated the tolerance of mango cultivars 'Haden', 'Palmer', 'Tommy Atkins' and 'Uba' grafted on rootstock 'Imbú' to salt stress using chlorophyll fluorescence. Plants were grown in modified Hoagland solution containing 0, 15, 30, and 45 mmol L-1 NaCl. At 97 days the parameters of the chlorophyll fluorescence (F0, Fm, Fv, F0/Fm, Fv/Fm, Fv'/Fm', ΦPSII = [(Fm'-Fs/(Fm'], D = (1- Fv'/Fm' and ETR = (ΦPSII×PPF×0,84×0,5 were determined. At 100 days, the leaf emission and leaf area, toxicity and leaf abscission indexes were determined. In all cultivars evaluated, in different degree, there were decreases in photochemical efficiency of photosystem II, enhanced concentrations from 15 mmol L-1 NaCl. The decreases in the potential quantum yield of photosystem II (Fv/Fm were 27.9, 18.7, 20.5, and 27.4%, for cultivars 'Haden', 'Palmer', 'Tommy Atkins', and 'Uba', respectively, when grown in 45 mmol L-1 NaCl. It was found decreases in leaf emission and mean leaf area in all cultivars from 15 mmol L-1 NaCl. There were increases in leaf toxicity of 33.0, 67.5, 41.6 and 80.8% and in leaf abscission of 71.8, 29.2, 32.5, and 67.9% for the cultivars 'Haden', 'Palmer', 'Tommy Atkins', and 'Uba' respectively, when grown in 45 mmol L-1 NaCl. Leaf toxicity and leaf abscission were not observed in 15 mmol L-1 NaCl. The decrease in Fv/Fm ratio were accompanied by decreasing in leaf emission and increased leaf toxicity index, showing, therefore, the potential of chlorophyll fluorescence in the early detection of salt stress in mango tree.

  11. Avaliação do uso de inibidores de etileno sobre a produção de compostos voláteis e de mangiferina em manga Evaluation of the use of ethylene inhibitors on production of volatile compounds and mangiferin in mango fruit

    2010-01-01

    Full Text Available Effects of two ethylene inhibitors, 1-methylcylopropene (1-MCP and aminoethoxyvinylglycine (AVG, on production of volatile compounds and mangiferin (a bioactive xanthone in 'Tommy Atkins' mango fruit were investigated. Volatile composition and mangiferin content, in treated and untreated fruits at three maturity, stages were determined by SPME-GC-MS and HPLC, respectively. These chromatographical analysis revealed that the volatile profiles and mangiferin concentrations were not significantly different, suggesting that the use of ethylene inhibitors does not affect the mango aroma and functional properties relative to this xanthone. Moreover, a simple, precise and accurate HPLC method was developed for quantifying mangiferin in mango pulp.

    Full Text Available ABSTRACT Caused by the vascular fungus Ceratocystis fimbriata, mango wilt is considered to be one of the most serious threats in mango-producing regions worldwide. However, changes in leaf gas exchange level and the mechanisms underlying host responses to this fungal infection remain poorly described. This study aimed to evaluate potential changes in the leaf gas exchange of different mango cultivars (Ubá, Espada, Haden and Tommy Atkins in response to two Brazilian isolates of C. fimbriata (CEBS15 and MSAK16 to non-invasively assess cultivar variability in relation to the basal level of resistance to mango wilt. Both isolates, regardless of the cultivar, caused reductions in stomatal conductance and, thus, a reduction in CO2 assimilation via diffusive limitations. Taking into account the full length of the internal lesion and the radial colonization of the stem tissues, both isolates showed equivalent aggressiveness when inoculated into the Haden and Tommy Atkins cultivars. Conversely, when compared to the CEBS15 isolate of C. fimbriata, the MSAK16 isolate was more aggressive in cv. Espada and less aggressive in cv. Ubá.

    Full Text Available ABSTRACT Irrigated fruit crops have an important role in the economic and social aspects in the region of the Sub-middle São Francisco River Valley. Thus, the aim of this study was to evaluate soil salinity and the productive aspects of the mango crop, cv. Tommy Atkins, fertigated with doses of potassium chloride (KCl and potassium sulfate (K2SO4 during two crop cycles (from January to March 2014 and from January to March 2015. The experiment was carried out in a strip-split-plot design and five potassium doses (50, 75, 100, 125 and 150% of the recommended dose as plots and two potassium sources (KCl and K2SO4 as subplots, with four replicates. Soil electrical conductivity (EC, exchangeable sodium (Na+ and potassium (K+ contents and pH were evaluated. In addition, the number of commercial fruits and yield were determined. The fertilization with KCl resulted in higher soil EC compared with K2SO4 fertigation. Soil Na+ and K+ contents increased with increasing doses of fertilizers. K2SO4 was more efficient for the production per plant and yield than KCl. Thus, under the conditions of this study, the K2SO4 dose of 174.24 g plant-1 (24.89 kg ha-1 or 96.8% of recommendation, spacing of 10 x 7 m was recommended for a yield of 23.1 t ha-1 of mango fruits, cv.

    We determined the influence of resin ducts, sap content, and fruit physicochemical features of four mango cultivars (Criollo, Manila, Ataulfo, and Tommy Atkins) on their susceptibility to the attack of the two most pestiferous fruit fly species infesting mangoes in Mexico: Anastrepha ludens (Loew) and Anastrepha obliqua (Macquart). We performed three studies: 1) analysis of resin ducts in mango fruit exocarp to determine the density and area occupied by resin ducts in each mango cultivar, 2) assessment of mango physicochemical features including fruit sap content, and 3) a forced infestation trial under field conditions using enclosed fruit-bearing branches to expose mangoes to gravid A. ludens or A. obliqua females. Infestation rates, development time from egg to prepupae and pupae, pupal weight, and percent of adult emergence, were assessed. 'Ataulfo' and 'Tommy Atkins' cultivars exhibited the highest resin duct density and sap content, the lowest infestation rate, and had a negative effect on immature development and pupal weight. In sharp contrast, 'Manila' and 'Criollo' cultivars, with the lowest resin duct density and sap content, were highly susceptible to A. ludens and A. obliqua attack. We conclude that sap content and the number, size, and distribution of resin ducts as well as firmness in mango fruit exocarp are all involved in the resistance of mango to A. ludens and A. obliqua attack. © The Authors 2017.

    2017-01-01

    Full Text Available This study aimed to evaluate the use of starch degradation index (SDI in the diagnosis of areas of impact injuries in 'Tommy Atkins' mango, in different maturation stages. The experiment layout was a fully randomized factorial design (5 x 2, represented by five maturation stages and two handlings, with and without impact, with four replicates. SDI was determined through a subjective scale of scores indicating mango pulp darkened areas by reaction with iodine-potassium iodide solution. Subsequently, these scores were correlated with physicochemical quality variables. The results showed no influence of impact on fruit quality, in any of the studied maturation stages. Moreover, soluble solid contents increased throughout maturation stages, regardless of whether the fruits suffered impact or not. As a result, SDI is unsuitable to indicate fruit impact injury. However, there is a good correlation between SDI and pulp color, vitamin C, pH, titratable acidity, soluble solids, SS/ TA ratio and non-reducing sugars.

    Historically, Mangifera indica L. cultivations have been widely planted in tropical areas of India, Africa, Asia, and Central America. However, at least 20 years ago its spreading allowed the development of some cultivars in Sicily, an island to the south of Italy, where the favourable subtropical climate and adapted soils represent the perfect field to create new sources of production for the Sicilian agricultural supply chain. Currently, cultivations of Kensington Pride, Keitt, Glenn, Maya, and Tommy Atkins varieties are active in Sicily and their products meet the requirements of local and European markets. Mango plants produce fleshy stone fruits rich in phytochemicals with an undisputed nutritional value for its high content of polyphenolics and vitamins. This review provides an overview of the antioxidant, anti-inflammatory, and anticancer properties of mango, a fruit that should be included in everyone's diet for its multifaceted biochemical actions and health-enhancing properties.

    In his minor essay from 1914, Some Reflections on Schoolboy Psychology, Freud placed immense significance upon the father-son relationship as enabling or inhibiting the individual quest towards a mature, separate, and healthy development. In this essay, I will explore Freud's observations to illuminate the journey taken by Assaff, a 34-year old man who, during the early stages of his adolescence, had a father who was emotionally absent due a traumatic experience during his military service in the Israeli Defense Forces. Through transference work, the impact of the emotional absence will be shown. I will demonstrate how the boy was able unconsciously to use the music of Tommy, a rock opera by the British band The Who, as a transitional object. I will show how that piece of music provided Assaff with the sense of hope that helped during the darker times of his adolescent.

    It had been studied the effect of the ionizing radiation (gamma) in mangoes for exportation, simulating the stage of preservation of the fruit during its transport, through the refrigeration in cold chamber. In a first stage they had been analyzed through loss of weight, pH, treatable acidity, soluble solid, texture and decomposition. Later, sensorial analyses had been become fulfilled (alterations of color, odor, flavor, texture). The assays had been carried through in two stadiums of maturation of the fruits, that is, 2 and 3, with the intention of studying optimum point of harvest for the best dosage of irradiation. The results disclose together that the treatment of the mangoes Tommy Atkins in the dose of 0,75 kGy was significant, with the fruit in stadium 2, for the retardation of the matureness and consequent profit of time for the exportation.

  9. Settlement

    Full Text Available The paper explores the idea of settlement in each of its three major senses: as a place of human habitation; as a fixed and stable order of habitation; and as a political consensus reconciling fractious groups. Arguing that traditional accounts of settlement depend, with a kind of pastoral nostalgia, upon a view of abstraction and social complexity as in themselves  harmful, it follows through the implications of the concept for ways of dealing with the stranger, and it uses a drawing by the nineteenth-century indigenous Australian artist Tommy McRae, done about 1890 and entitled Corroboree, or William Buckley and dancers from the Wathaurong people, to propose a counterfactual model through which a settlement with the stranger might be imagined.

O objetivo deste trabalho foi avaliar o emprego de estratégias para reduzir o período juvenil e as trabalhosas polinizações manuais em mangueira, de forma a acelerar o desenvolvimento de novas cultivares da espécie para o Semiárido brasileiro. Foram identificadas plantas isoladas das cultivares Haden e Espada dentro de plantios comerciais da cultivar Tommy Atkins, numa fazenda exportadora de manga, em Petrolina-PE. Mudas das progênies foram transplantadas com seis meses de idade para o campo. O manejo para a indução floral foi realizado com poda, controle da irrigação e aplicação de Paclobutrazol e nitrato de potássio. O DNA extraído das progênies e parentais foi submetido a análises com marcadores microssatélites publicados para Mangifera indica L. O manejo combinado foi eficiente para induzir a floração e a frutificação em, aproximadamente, 70% das progênies após dois anos e meio de transplantio. Dos 94 indivíduos analisados com três microssatélites, 83% foram identificados como híbridos entre 'Haden' x 'T. Atkins'. Dos 401 indivíduos analisados com um microssatélite, 10% foram identificados como híbridos entre 'Espada' x 'T. Atkins'. A estratégia adotada foi eficiente para reduzir o período juvenil e evitar os trabalhosos cruzamentos manuais em mangueira, sendo que o desenvolvimento de novas cultivares da espécie para a região pode ser concluído com oito a dez anos, incluindo as rigorosas avaliações agronômicas.Mango is one of the most important fruit crop in the Brazilian Semi-Arid region.

    Forced-air distribution systems (duct systems) typically are installed out of sight for aesthetic reasons, most often in unconditioned areas such as attics or crawlspaces. Any leakage of air to or from the duct system in unconditioned space not only loses energy, but impacts home and equipment durability and indoor air quality. An obvious solution is to bring the duct system into the interior of the house, either by sealing the area where the ducts are installed (attic or crawlspace) or by building an interior cavity or chase above the ceiling plane (raised ceiling or fur-up chase) or below the ceiling plane (dropped ceiling or fur-down) for the duct system. In this project, Building America Partnership for Improved Residential Construction team partnered with Tommy Williams Homes to implement an inexpensive, quick, and effective method of building a fur-down chase.

Apesar de existirem muitos cultivares, o cultivo tem sido realizado basicamente com o cultivar 'Tommy Atkins' e existem poucos trabalhos sobre caracterização e análise da diversidade genética dos genótipos disponíveis. Por isso, o objetivo deste trabalho foi estudar a diversidade genética de 15 cultivares de mangueiras, produzidos na Zona da Mata Mineira, sendo oito brasileiros e sete oriundos da Flórida (EUA. Para isto, frutos maduros dos 15 cultivares foram colhidos e analisados química e fisicamente. Os cultivares que se apresentaram mais similares foram 'Kent' e 'Palmer'. O cultivar 'Extrema' não se agrupou com os outros pelo método de agrupamento UPGMA, e, por esta análise houve a separação dos cultivares brasileiros e norte-americanos. Quanto às características químicas, a técnica de componentes principais não agrupou os cultivares 'Extrema' e 'Tommy Atkins' com os demais; já quanto às características físicas, observou-se a mesma separação obtida pelo agrupamento UPGMA, com exceção do cultivar 'Extrema' que, neste caso, agrupou-se com os demais cultivares.

    Many polyphenolics contained in mango have shown anticancer activity. The objective of this study was to compare the anticancer properties of polyphenolic extracts from several mango varieties (Francis, Kent, Ataulfo, Tommy Atkins, and Haden) in cancer cell lines, including Molt-4 leukemia, A-549 lung, MDA-MB-231 breast, LnCap prostate, and SW-480 colon cancer cells and the noncancer colon cell line CCD-18Co. Cell lines were incubated with Ataulfo and Haden extracts, selected on the basis of their superior antioxidant capacity compared to the other varieties, where SW-480 and MOLT-4 were statistically equally most sensitive to both cultivars followed by MDA-MB-231, A-549, and LnCap in order of decreasing efficacy as determined by cell counting. The efficacy of extracts from all mango varieties in the inhibition of cell growth was tested in SW-480 colon carcinoma cells, where Ataulfo and Haden demonstrated superior efficacy, followed by Kent, Francis, and Tommy Atkins. At 5 mg of GAE/L, Ataulfo inhibited the growth of colon SW-480 cancer cells by approximately 72% while the growth of noncancer colonic myofibroblast CCD-18Co cells was not inhibited. The growth inhibition exerted by Ataulfo and Haden polyphenolics in SW-480 was associated with an increased mRNA expression of pro-apoptotic biomarkers and cell cycle regulators, cell cycle arrest, and a decrease in the generation of reactive oxygen species. Overall, polyphenolics from several mango varieties exerted anticancer effects, where compounds from Haden and Ataulfo mango varieties possessed superior chemopreventive activity.

Esta última é um clone selecionado da 'Haden 2H'. Foram avaliadas a produção, resistência às doenças e mosca-das-frutas bem como as características físicas e químicas dos frutos. A produtividade das cultivares foi avaliada em Votuporanga-SP, utilizando um ensaio em blocos completos ao acaso, com as seis cultivares e cinco repetições, com três plantas por parcela. A cultivar Palmer mostrou-se a mais produtiva, revelando boa adaptação às condições edafoclimáticas do local. Nenhuma cultivar foi resistente a todas as doenças, e a 'Haden 2H' foi a mais suscetível. A 'Espada Vermelha' mostrou-se resistente à mosca-das-frutas, e a 'Votupa' apresentou a maior porcentagem de polpa, próxima à das comerciais 'Van Dyke', 'Tommy Atkins' e 'Palmer'. O valor nutritivo e a composição química dos frutos foram avaliados no Instituto Agronômico e no Instituto de Tecnologia de Alimentos, em Campinas. A cultivar Espada Vermelha distinguiu-se das demais por ter apresentado características diferenciadas em alguns dos parâmetros químicos avaliados, principalmente quanto aos teores de minerais, carotenóides totais e de lipídeos, que proporcionaram intenso aroma e coloração aos seus frutos. 'Votupa', 'Palmer' e 'Van Dyke' apresentaram frutos mais ácidos e mais calóricos, enquanto as cultivares Espada Vermelha, Tommy Atykns e Haden 2H mostraram frutos de baixa acidez e de menor valor calórico.Two new mango cultivars, IAC 103 Espada Vermelha and IAC 109 Votupa, resistant to the mango wilt caused by the fungus Ceratocystis fimbriata and selected by the "Instituto Agronômico de Campinas" (IAC, were compaired to four Floridian cultivars

Patients and methods: A randomized, prospective intervention study was undertaken among 55 elderly patients. Three intervention groups were evaluated: a muscle force training group; a balance and muscle force training group; and a self-administered training group. Each group underwent 1-hour-long training sessions, twice a week, for 3 months. Postural stability was measured at onset, after 3 months, and after 6 months. Time-domain-dependent body sway variables were calculated. The fall rate was evaluated for 3 years. General health related quality of life (HRQoL was measured with a 15D instrument. Postural stability was used as a primary outcome, with QoL and falls used as secondary outcomes. Results: Muscle force trainees were able to undertake training, progressing towards more strenuous exercises. In posturography, the number of spiky oscillations was reduced after training, and stationary fields of torque moments of the ankle increased, providing better postural stability in all groups; in particular, the zero crossing rate of weight signal and the number of low variability episodes in the stabilogram were improved after training. While no difference was found between different training groups in posturography outcomes, a reduction of fall rate

    The purpose of the present study was to verify and compare the chemical and physical-chemical behaviour of mango cv. Tommy Atkins subjected to hydrothermal treatment and irradiation at doses 0.4 and 1.0 kGy, to complement the studies by SABATO et al (2009) in the real transport of irradiated mangoes from Brazil to Canada. These studies allowed to compare the performance of irradiation with heat treatment on the preservation of the characteristics of mango for export. For these reason fruits were divided into groups: control, heat bath (46 degree C for 90 min), at dose 0.4 kGy and at dose 1.0 kGy. The fruits were stored at low temperature (11 degree C {+-} 2) for 14 days, and then at room temperature (23 degree C {+-} 2) until the end of its useful life. During the period of cold storage the analysis were performed at intervals of 7 days and every 3 days when kept at room temperature. The results indicated that the dose of 1.0 kGy was the only group that kept the fruit with the skin color on stage 3 throughout the experimental period, but provided a greater loss of texture degradation and the levels of total acidity in the fruits with green skin. It was noted that only the control group showed higher levels of citric acid and succinic acid in the last day of the experiment. There were no significant differences in soluble solids, total sugars and evaluation of weight in relation to treatments. The analysis of visual observation indicated that the heat bath group was the one with the highest number of fruit drop by decomposition with approximately 55%. It was concluded that irradiation is more effective in preserving the quality of mangoes cv. Tommy Atkins, reducing the appearance of rot or shriveling in relation to heat treatment. However, the preservation of the skin of fruit is not concurrently influenced by its intrinsic nature, since, internally, the fruits continue their normal maturation, independent of the applied dose.

    This study assessed the efficacy of chitosan (Chi) and Cymbopogon citratus (D.C. ex Nees) Stapf. essential oil (CCEO) combinations to control the mycelial growth of five pathogenic Colletotrichum species (C. asianum, C. siamense, C. fructicola, C. tropicale and C. karstii) in vitro, as well as the anthracnose development in guava (Psidium guajava L.) cv. Paluma, mango (Mangifera indica L.) cv. Tommy Atkins and papaya (Carica papaya L.) cv. Papaya artificially inoculated with these species. Combinations of Chi (2.5, 5 or 7.5mg/mL) and CCEO (0.15, 0.3, 0.6 or 1.25μL/mL) inhibited the mycelial growth of all tested fungal species in vitro. Examined Chi-CCEO combinations showed additive or synergistic interactions to inhibit the target Colletotrichum species based on the Abbott index. Coatings formed by synergistic Chi (5mg/mL) and CCEO (0.15, 0.3 or 0.6μL/mL) combinations decreased anthracnose lesion development in guava, mango and papaya inoculated with any of the tested Colleotrichum species during storage. Overall, anthracnose lesion development inhibition in fruit coated with synergistic Chi-CCEO combinations was higher than that observed in fruit treated with synthetic fungicides. These results show that the application of coatings formed by Chi-CCEO synergistic combinations could be effective to control postharvest anthracnose development in fruit.

This article presents a discourse analysis of 101 responses to 98 questions that were posted on 14 different Internet-based mental health services in Norway and Sweden. We aimed to examine and describe the dominant understandings and favored recommendations in the services’ answers, and we reflected upon the social consequences of those answers. The services generally understood life struggles as an abnormal state of mind, life rhythms, or self-reinforcing loops. Internet-based mental health services primarily counsel service users to seek help, talk to health care professionals face-to-face, and discuss their life struggles openly and honestly. They also urge service users to take better care of themselves and socialize with other people. However, such answers might enhance the individualization of life problems, masking social origin and construction. Consequently, the services are challenged to include social explanations in their answers and strengthen their responsibility to amplify peoples’ messages at a societal level. Potentially, such answers could strengthen democratic structures and put pressure on social equity.Keywords: depression, e-mental health, health psychology, Internet, public health

    Mango (Mangifera indica L.) is a fruit rich in flavor and nutritional values, which is an excellent candidate for producing chips. The objective of this study was to develop high-quality mango chips using vacuum frying. Mango ("Tommy Atkins") slices were pretreated with different maltodextrin concentrations (40, 50, and 65, w/v), osmotic dehydration times (45, 60, and 70 min), and solution temperatures (22 and 40 degrees C). Pretreated slices were vacuum fried at 120, 130, and 138 degrees C and product quality attributes (oil content, texture, color, carotenoid content) determined. The effect of frying temperatures at optimum osmotic dehydration times (65 [w/v] at 40 degrees C) was assessed. All samples were acceptable (scores > 5) to consumer panelists. The best mango chips were those pretreated with 65 (w/v) concentration for 60 min and vacuum fried at 120 degrees C. Mango chips under atmospheric frying had less carotenoid retention (32%) than those under vacuum frying (up to 65%). These results may help further optimize vacuum-frying processing of high-quality fruit-based snacks.

    The β-carotene content of fresh and dried mangoes commonly consumed in Kenya was evaluated and converted to retinol equivalent (RE). Mango fruits of varieties Ngowe, Apple, and Tommy Atkins were harvested at mature green, partially ripe, and ripe stages and their β-carotene content analyzed. The stability of β-carotene in sun dried mangoes was also studied over 6 months under usual marketing conditions used in Kenya. The effect of using simple pretreatment methods prior to drying of mango slices on retention of β-carotene was as well evaluated. In amounts acceptable to children and women, fresh and dried mangoes can supply 50% or more of the daily required retinol equivalent for children and women. Stage of ripeness, variety, postharvest holding temperature, method of drying, and storage time of dried mango slices affected β-carotene content and consequently vitamin A value of the fruits. Apple variety grown in Machakos had the highest β-carotene. It exceeded the daily RE requirements by 11.8% and 21.5% for women and children respectively. Fresh or dried mangoes are a significant provitamin A source and should be included in food-based approaches aiming to reduce vitamin A deficiency.

As this country is already a great producer and exporter of tropical fruits, ionizing radiation has been the subject of studies in many commodities. An important project has been carried out to increase the commercial use of gamma radiation in our country. Instituto de Pesquisas Energeticas e Nucleares (IPEN)-CNEN/SP together with field producers in northeast region and partners like International Atomic Energy Agency (IAEA), CIC, Empresa Brasileira Pesquisa na Agricultura (EMBRAPA) joined to demonstrate this technology, its application and commercial feasibility. The objective of this study is to show advances in feasibility demonstrate the quality of the irradiated fruits in an international consignment from Brazil to Canada. In this work, Tommy Atkins mangoes harvested in northeast region of Brazil were sent to Canada. The fruits were treated in a gamma irradiation facility at doses 0.4 and 1.0 kGy. The control group was submitted to hydrothermal treatment (46 {sup o}C for 110 min). The fruits were stored at 11 {sup o}C for 10 days until the international transportation and kept at an environmental condition (22 {sup o}C) for 12 days, where their physical-chemical and sensorial properties were evaluated. The financial part of the feasibility study covers the scope of the investment, including the net working capital and production costs.

Pregnancies of obese women are often defined as "high-risk" for the purposes of clinical care, with many well documented risks to the mother and developing baby. Maternal physiology and metabolism is dysregulated in the context of obesity, which may contribute to some of the adverse outcomes during pregnancy. Furthermore, maternal obesity has been hypothesized to cause harmful effects for the developing baby through "early life programming." This review will examine evidence from human studies for outcomes of offspring from obese women during pregnancy, during labor, during the neonatal period, and later in life. Keywords: pregnancy, short-term, physiology, metabolism, early life programming, neonatal complications, adverse intrauterine environment

    This study investigated the effect of pulsed light (PL) on the respiratory rate, quality (firmness, color and soluble solid content), bioactive compounds (ascorbate and carotenoid) and total antioxidant activity of fresh-cut "Tommy Atkins" mangoes. Fresh-cut mangoes were subjected to PL treatments: control (0P), 1 pulse (1P; 0.7 J cm -2 ), 4 successive pulses (4P; 2.80 J cm -2 ) and 1 pulse per day for 4 days (1P4D; 2.80 J cm -2 ) before storage for 7 days at 6 °C. The 1P and the 4P treatments reduced fresh mass loss during storage, while 4P-treated samples also showed a slower decline of yellow color, as shown by parameter b and overall better visual appearance. After 7 days of storage, total ascorbate content was 40% higher in the 1P4D treatment than in control, whereas total carotenoid content (0.894 mg g -1 FM) and total antioxidant activity (144 μmol trolox 100 g -1 FM) were the highest in the 4P-treated samples. Results suggest that PL mode of application is more important than the fluence or final dose received by fresh-cut mangoes; moreover, 4P is an effective method to preserve, or even improve quality of fresh-cut mangoes.

    BA-PIRC has worked with several community-scale builders within the hot humid climate zone to improve performance of production, or community scale, housing. Tommy Williams Homes (Gainesville, FL), Lifestyle Homes (Melbourne, FL), and Habitat for Humanity (various locations, FL) have all been continuous partners of the BA Program and are the subjects of this report to document achievement of the Building America goal of 30% whole house energy savings packages adopted at the community scale. The scope of this report is to demonstrate achievement of these goals though the documentation of production-scale homes built cost-effectively at the community scale, and modeled to reduce whole-house energy use by 30% in the Hot Humid climate region. Key aspects of this research include determining how to evolve existing energy efficiency packages to produce replicable target savings, identifying what builders' technical assistance needs are for implementation and working with them to create sustainable quality assurance mechanisms, and documenting the commercial viability through neutral cost analysis and market acceptance. This report documents certain barriers builders overcame and the approaches they implemented in order to accomplish Building America (BA) Program goals that have not already been documented in previous reports.

    Full Text Available The effects of thermal gradients on stem add one methodological constraint for estimating sap flow through the Granier method (thermal dissipation probe. The present work studied the effect of natural thermal gradients on estimates of sap flow by using thermal dissipation probe in mango plants. The study was carried by using mango plants of the cultivar Tommy Atkins during two development stages: (a during the initial development phase of plants with leaf area of 0.66, 0.73, 1.78 m2 , planted in 15 and 50 liters pots. The study was carried in a greenhouse environment and in the field. Different thermal shields were used around the stem of plants in pots in order to minimize the effects of thermal natural gradients. The measurements of thermal differences were obtained from an adult plant with high leaf density and small exposition of branches to solar radiation. Sensors placed in stems of adult plant with high leaf density provided smaller thermal gradients compared to those inserted in young plant stems. It is necessary to cover the whole branch with neoprene and a shield (skirt type of aluminum paper above and below the location of probe insertion for exposed branches. The air temperature at 2 m height may be used efficiently to correct thermal gradients. It is indispensable the correction of natural thermal gradients in the stem for adequate estimating sap flow density by the Granier method.

    Microarray and other genome-wide technologies allow a global view of gene expression that can be used in several ways and whose potential has not been yet fully discovered. Functional insight into expression profiles is routinely obtained by using gene ontology terms associated to the cellular genes. In this article, we deal with functional data mining from expression profiles, proposing a novel approach that studies the correlations between genes and their relations to Gene Ontology (GO). We implemented this approach in a public web-based application named Fun&Co. By using Fun&Co, the user dissects in a pair-wise manner gene expression patterns and links correlated pairs to gene ontology terms. The proof of principle for our study was accomplished by dissecting molecular pathways in muscles. In particular, we identified specific cellular pathways by comparing the three different types of muscle in a pairwise fashion. In fact, we were interested in the specific molecular mechanisms regulating the cardiovascular system (cardiomyocytes and smooth muscle cells). We applied here Fun&Co to the molecular study of cardiovascular system and the identification of the specific molecular pathways in heart, skeletal and smooth muscles (using 317 microarrays) and to reveal functional differences between the three different kinds of muscle cells.

    Paclobutrazol (PBZ) is a growth regulator used in agricultural systems whose purpose is the control of vegetative growth, stimulating the reproductive capacity of plants. This growth regulator remains active in soil for a long time and its half-life varies with the type of soil and climatic conditions, can severely affect the development of crops. This work aimed to study the residues / metabolites of {sup 14}C-PBZ in mango pulp Tommy Atkins. The tests were performed with mangoes grown in pots stainless steel and application of {sup 14}C-PBZ was performed by the soil projection of the crown, and the mangoes tested in two periods, one year and two years after application. To evaluate the levels of residues of {sup 14}C-PBZ was realize the burning of 200 mg of pulp on biological oxidized and detached {sup 14}CO{sub 2} was detected by liquid scintillation spectrophotometer. The results were 1.65 % of residue of PBZ on fruit collected after two years of application and 4.30 % of residue of PBZ collected on fruit after a year of application and also can see that the product remained in the soil for more than one year, is translocated to the plant and reach the edible part, the pulp fruit. The identification of residual {sup 14}C- PBZ/metabolites by thin-layer chromatography did not reveal any pattern of PBZ / metabolites due to the low activity detected in the samples. Therefore, another procedure was performed for extraction and then analyzed by high performance liquid chromatography (HPLC) for detection of metabolites in the PBZ of mango pulp. (author)

    The effects of processing on the flavor and texture properties of 4 mango cultivars available in the U.S. were studied. Descriptive panelists evaluated fresh mango, mango purée, and mango sorbet prepared from each cultivar. Purées were made by pulverizing mango flesh, passing it through a china cap, and heating it to 85 °C for 15 s. To prepare the sorbets, purées were diluted with water (1:1), sucrose was added to increase the total soluble solids (TSS) to 32 ± 2 °Brix, and bases were frozen in a batch-type ice cream freezer. Processing fresh mangoes into mango purée generally decreased fruity character and mango identity and led to the appearance of a cooked note. Many of the flavor distinctions among cultivars carried over from fresh to purée samples, but much of the texture variation was lost. Thermal processing had differing effects on the flavor of the cultivars, and therefore, results suggest that mango cultivars for purées should be selected based on properties after thermal treatment. Processing purées into sorbets minimized flavor variation among cultivars, although Tommy Atkins sorbet was relatively high in green and green-viney character and low in caramelized flavor compared to the other cultivars in sorbet. Based on the current study only very distinct flavor properties of mango cultivars may carry over to sorbets. Findings from the present study will help mango purée and sorbet manufacturers select appropriate cultivars for their products by understanding the transformation that mango undergoes as it is processed into mango purée and subsequently to mango sorbet. © 2012 Institute of Food Technologists®

Tommy Atkins durante el almacenamiento. El modelo de análisis de variancia ajustado no permite observar diferencias entre los niveles de los factores, sino solamente diferencias entre cada nivel y el promedio general. Permite observar si existen diferencias entre las pendientes de cada nivel y la pendiente general, y no brinda información del nivel utilizado como base al correr el modelo. El modelo de análisis de regresión múltiple permite observar diferencias entre cada nivel y el nivel utilizado como base, permite observar si existen diferencias entre las pendientes de cada nivel y la pendiente del nivel utilizado como base y brinda información acerca de todos los niveles del factor. Al evaluar el efecto de los 4 diferentes tipos de empaque, sobre las características de calidad del mango, se llega a la conclusión de que los empaques microperforado y termoencogible son los más adecuados. El empaque termoencogible resulta en menor desarrollo de olores extraños que el control, y ambos empaques resultan en niveles de dulzor iguales a los del control, no así los 2 polietilenos, en los que el dulzor aumenta con el tiempo, indicando una maduración más rápida que en el control.

    Mammographic density has been shown to be a strong independent predictor of breast cancer and a causative factor in reducing the sensitivity of mammography. There remain questions as to the use of mammographic density information in the context of screening and risk management, and of the association with cancer in populations known to be at increased risk of breast cancer. To assess the association of breast density with presence of cancer by measuring mammographic density visually as a percentage, and with two automated volumetric methods, Quantra™ and VolparaDensity™. The TOMosynthesis with digital MammographY (TOMMY) study of digital breast tomosynthesis in the Breast Screening Programme of the National Health Service (NHS) of the United Kingdom (UK) included 6020 breast screening assessment cases (of whom 1158 had breast cancer) and 1040 screened women with a family history of breast cancer (of whom two had breast cancer). We assessed the association of each measure with breast cancer risk in these populations at enhanced risk, using logistic regression adjusted for age and total breast volume as a surrogate for body mass index (BMI). All density measures showed a positive association with presence of cancer and all declined with age. The strongest effect was seen with Volpara absolute density, with a significant 3% (95% CI 1-5%) increase in risk per 10 cm 3 of dense tissue. The effect of Volpara volumetric density on risk was stronger for large and grade 3 tumours. Automated absolute breast density is a predictor of breast cancer risk in populations at enhanced risk due to either positive mammographic findings or family history. In the screening context, density could be a trigger for more intensive imaging. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Mango (Mangifera indica L.) is a tropical fruit grown worldwide with excellent nutritional value and widely attributed health-promoting properties. Extensive studies have been made of the high concentrations of phenolic antioxidants in mango peels, seeds, and leaves, yet less is known about the phenolic antioxidants of mango fruit pulp. Five varieties of mangoes from four countries were evaluated with multiple harvests over 1 year to compare the beta-carotene, ascorbic acid, and total phenolic contents and antioxidant capacities of the fruit pulp and to compare the phenolic profiles of the individual varieties. To minimize ripeness variability, only soft fruit (0.5-1 N compression) with a minimum of 10% soluble solids were used for these measurements. Ascorbic acid ranged from 11 to 134 mg/100 g of pulp puree, and beta-carotene varied from 5 to 30 mg/kg among the five varieties. Total phenolic content ranged from 19.5 to 166.7 mg of gallic acid equivalents (GAE)/100 g of puree. The varieties Tommy Atkins, Kent, Keitt, and Haden had similar total phenolic contents, averaging 31.2+/-7.8 mg GAE/100 g of puree, whereas the variety Ataulfo contained substantially higher values. Similar trends were observed in the DPPH radical scavenging activities among the five varieties. In contrast, the country of origin and harvest dates had far less influence on these parameters. Ataulfo mangoes contained significantly higher amounts of mangiferin and ellagic acid than the other four varieties. Large fruit-to-fruit variations in the concentrations of these compounds occurred within sets of mangoes of the same cultivar with the same harvest location and date.

    Full Text Available Abstract Background Internal control genes with highly uniform expression throughout the experimental conditions are required for accurate gene expression analysis as no universal reference genes exists. In this study, the expression stability of 24 candidate genes from Triticum aestivum cv. Cubus flag leaves grown under organic and conventional farming systems was evaluated in two locations in order to select suitable genes that can be used for normalization of real-time quantitative reverse-transcription PCR (RT-qPCR reactions. The genes were selected among the most common used reference genes as well as genes encoding proteins involved in several metabolic pathways. Findings Individual genes displayed different expression rates across all samples assayed. Applying geNorm, a set of three potential reference genes were suitable for normalization of RT-qPCR reactions in winter wheat flag leaves cv. Cubus: TaFNRII (ferredoxin-NADP(H oxidoreductase; AJ457980.1, ACT2 (actin 2; TC234027, and rrn26 (a putative homologue to RNA 26S gene; AL827977.1. In addition of these three genes that were also top-ranked by NormFinder, two extra genes: CYP18-2 (Cyclophilin A, AY456122.1 and TaWIN1 (14-3-3 like protein, AB042193 were most consistently stably expressed. Furthermore, we showed that TaFNRII, ACT2, and CYP18-2 are suitable for gene expression normalization in other two winter wheat varieties (Tommi and Centenaire grown under three treatments (organic, conventional and no nitrogen and a different environment than the one tested with cv. Cubus. Conclusions This study provides a new set of reference genes which should improve the accuracy of gene expression analyses when using wheat flag leaves as those related to the improvement of nitrogen use efficiency for cereal production.

    Full Text Available O presente trabalho tem como principal objetivo construir uma análise acerca do debate, hoje crescente, do Ensino de História. Mais especificamente, expandir para a pesquisa acadêmica brasileira, os estudos de um campo relativamente novo, denominado de "pedagogia do ensino dos traumas coletivos", com ênfase no Holocausto. É latente a necessidade de revisitarmos os currículos, em quaisquer níveis de ensino, adequando-os às demandas sociais de nosso tempo presente. Buscaremos neste texto discutir o papel da instituição escolar, do professor e do material didático enquanto ferramenta de ensino que visa combater as manifestações de ódio presentes tanto na estrutura do Estado, quanto no corpo social. Existe hoje uma crescente necessidade de avaliação do que temos aprendido e, ainda mais, que temos ensinado sobre os eventos traumáticos. De forma especial, na educação brasileira, o ensino de traumas coletivos é tratado, em sua maioria, como nota explicativa em temas mais abrangentes, como o Holocausto em relação com a Segunda Guerra Mundial. O currículo e os instrumentos pedagógicos disponíveis no Brasil não dão o necessário suporte aos agentes do processo educacional. Desta feita, objetivamos ainda apresentar e problematizar os materiais didáticos do YadVashem, museu responsável pela memória do Holocausto, e a forma como se tem trabalhado o tema em Israel, seus métodos e objetivos. Nesse sentido, utilizaremos como fonte três materiais didáticos, desenvolvidos pelo YadVashem, distribuídos nos diferentes níveis da educação, de acordo com a filosofia espiral de ensino: "Tommy", "Porque Naftali se llama Naftali" e "Cuatro vidas distintas y muy parecidas"

    Full Text Available O objetivo deste trabalho foi avaliar a respiração e produção de etanol e etileno em mangas armazenadas sob reduzidas concentrações de oxigênio (O2 e elevadas concentrações de dióxido de carbono (CO2. Mangas pré-climatéricas das cultivares Kent e Tommy Atkins foram armazenadas, sob fluxo contínuo, por 14 ou 21 dias, a 12°C em três concentrações de O2: 3%, 5% ou 21% em mistura com concentrações de 5%, 15%, 25%, 35%, 45%, 50% ou 70% de CO2. O tratamento-testemunha constou de armazenagem em ar sob fluxo contínuo. Após o período em atmosfera controlada (AC, as mangas foram transferidas e mantidas por 5 dias em ar a 20°C. Mangas sob concentrações de 50% e 70% de CO2 produziram mais etanol que nas demais concentrações de CO2. A redução para 3% de O2 na atmosfera de armazenagem aparentemente não teve efeito adicional ao CO2 na produção de etanol. A atividade respiratória de mangas em AC com CO2 acima de 45% foi muito mais intensa do que a respiração sob as concentrações de CO2 mais baixas; a produção de etileno, no entanto, esteve suprimida, e, mesmo após a transferência para ar, não se recuperou, permanecendo inferior aos demais tratamentos. A queda na atividade respiratória das mangas armazenadas a 50% e 70% de CO2, quando foram transferidas para ar a 20°C indica que as elevadas concentrações de CO2 causaram dano irreparável aos tecidos.

    Germplasm collections are an important source for plant breeding, especially in fruit trees which have a long duration of juvenile period. Thus, efforts have been made to study the diversity of fruit tree collections. Even though mango is an economically important crop, most of the studies on diversity in mango collections have been conducted with a small number of genetic markers. We describe a de novo transcriptome assembly from mango cultivar 'Keitt'. Variation discovery was performed using Illumina resequencing of 'Keitt' and 'Tommy Atkins' cultivars identified 332,016 single-nucleotide polymorphisms (SNPs) and 1903 simple-sequence repeats (SSRs). Most of the SSRs (70.1%) were of trinucleotide with the preponderance of motif (GGA/AAG)n and only 23.5% were di-nucleotide SSRs with the mostly of (AT/AT)n motif. Further investigation of the diversity in the Israeli mango collection was performed based on a subset of 293 SNPs. Those markers have divided the Israeli mango collection into two major groups: one group included mostly mango accessions from Southeast Asia (Malaysia, Thailand, Indonesia) and India and the other with mainly of Floridian and Israeli mango cultivars. The latter group was more polymorphic (FS=-0.1 on the average) and was more of an admixture than the former group. A slight population differentiation was detected (FST=0.03), suggesting that if the mango accessions of the western world apparently was originated from Southeast Asia, as has been previously suggested, the duration of cultivation was not long enough to develop a distinct genetic background. Whole-transcriptome reconstruction was used to significantly broaden the mango's genetic variation resources, i.e., SNPs and SSRs. The set of SNP markers described in this study is novel. A subset of SNPs was sampled to explore the Israeli mango collection and most of them were polymorphic in many mango accessions. Therefore, we believe that these SNPs will be valuable as they recapitulate and

    Full Text Available A mangicultura praticada no Submédio do Vale do São Francisco é considerada um dos principais destaques no comércio externo do País. Dentre as diversas variedades cultivadas, a Tommy Atkins é a que representa a maior parte das exportações. Entretanto, a magnitude das perdas por podridões pós-colheita, causadas por fungos Botryosphaeriaceae, é sempre uma grande preocupação para exportadores e importadores da fruta. A busca por métodos de controle mais eficazes e limpos é uma tendência mundial. Nesse sentido, o objetivo deste trabalho foi avaliar a reação de frutos, de 47 acessos de mangueiras, quanto à resistência aos fungos Fusicoccum aesculis e Neofusicoccum parvum. As inoculações foram realizadas mediante deposição de disco do meio de cultura batata-dextrose-ágar (BDA, contendo estruturas do patógeno sobre duas posições opostas na região equatorial da manga, mantido, posteriormente, por 24 horas em câmara úmida. Foram realizadas medições das lesões até o sétimo dia, com uma régua milimetrada. Com os registros dos crescimentos das lesões, foram calculadas as taxas diárias de crescimento da lesão (TDCL's para cada acesso. As maiores TDCLs foram observadas nos acessos 'Roxa' e 'Lita', quando inoculados com F. aesculis, e nos acessos 'Roxa', 'Ruby', 'Papo de peru', 'CPAC 22/93', 'Pingo-de-ouro', 'Pêssego' e 'M13269', quando inoculados com N. parvum. Os acessos 'Nego-não-chupa', 'Manga-d'água', 'Juazeiro VI', 'Juazeiro VII' e 'Favo-de-mel' foram os que apresentaram, concomitantemente, as menores TDCLs para ambos os patógenos e diferenças significativas em relação aos demais acessos.

    The Mexican fruit fly, Anastrepha ludens (Loew), is a quarantine pest in mango (Mangifera indica L.) that can be controlled by using a hot water treatment (HWT). This treatment is normally followed by a 30-min hydrocooling (HYC) process that reduces the negative effects that the treatment has on fruit quality. However, if hot water-treated fruits are immediately immersed in water at 21 °C, the survival rate of third-instar A. ludens may be increased. The current approved treatment protocol states that if HYC is used, then treated fruit should undergo an additional 10-min HWT or on platform for 30 min before HYC. We aimed to determine the efficacy of HWT without an additional 10-min treatment before being subjected to HYC, while taking into consideration that the most important conditions are the temperature of the fruit core throughout treatment and the type of infestation, either oviposition or inoculation. Two experimental tests were conducted. Our first aim was to determine the effectiveness of HWT followed by HYC using three varieties and different size classes of mangoes ('Ataulfo' 200-375 and 401-570 g; 'Tommy Atkins' 401-500 and 501-700 g; 'Kent' 401-500 g). The four treatment combinations used to test HWT and immediate HYC at 21 °C were 1) HWT, 2) HWT/HYC, 3) HWT + 10 min/HYC, and 4) HWT/30 min on platform/HYC; an independent experiment was used for each variety. The second aim was to validate the HWT/HYC combination by performing confirmatory tests in commercial packing houses. The results showed that as long as the mango core temperature reached 45 °C during the HWT, it was not necessary to add the 10-min treatment to the HWT before HYC at 21 °C was applied. To ensure that the larvae are subjected to the HWT treatment for sufficient time to be lethal, the temperature of the fruit core throughout the treatment must be recorded. © The Authors 2017.

    A series of methods has been used to evaluate metal ceramic bond strength. However, little attention has been paid to the wettability and interfacial reactions of dental porcelain/alloy systems, which may affect the bond strength of metal ceramic restorations. The purpose of this study was to understand the wetting and spreading behaviors, the interfacial reactions, and the bonding mechanism of ceramic to metal with TiO2 and MoO3 added to the dental porcelain. Two leucite-reinforced dental porcelains were used in the study. Twelve Co-Cr alloy sheets (15 × 10 × 2 mm) divided into 2 groups were used to evaluate the wetting process, and 12 Co-Cr alloy sheets (25 × 3 × 0.5 mm) (Bego) divided into 2 groups were used for the 3-point bond strength test. The wetting process of the porcelain/alloy systems was observed in situ with a Tommi optical dimension measurement system using a modified sessile drop method. The reaction products of the interfacial region were determined by Raman spectra analyses. Metal ceramic specimens were tested in 3-point bending at a crosshead speed of 1.5 mm/min according to ISO 9693 requirements, and the results were statistically analyzed with 1-way ANOVA (α=.05). The addition of TiO2 and MoO3 in the dental porcelain improved the wettability of the dental porcelain/Co-Cr alloy system. The bond strength of the porcelain modified with TiO2 and MoO3 was 43 ±2 MPa and that of the unmodified porcelain was 38 ±3 MPa. The fracture of the 2 metal ceramic systems occurred near the porcelain layer. The application of TiO2 and MoO3 to the leucite-reinforced porcelain can improve the wettability of porcelain on alloy. Porcelain/alloy wettability can be used as a guide to improve the bonding property between dental porcelain and alloys. Copyright © 2013 Editorial Council for the Journal of Prosthetic Dentistry.

Our hypothesis, which was based on the different functions of the ACL bundles, was that the visibility of the anteromedial graft would have an impact on anteroposterior stability, and the visibility of the posterolateral graft on rotational stability of the knee. Methods: This study is a level II, prospective clinical and MRI study (NCT02000258. The study involved 75 patients. One experienced orthopedic surgeon performed all double-bundle ACL reconstructions. Two independent examiners made the clinical examinations at 2-year follow-up: clinical examination of the knee; KT-1000, International Knee Documentation Committee and Lysholm knee evaluation scores; and International Knee Documentation Committee functional score. The MRI evaluations were made by two musculoskeletal radiologists separately, and the means of these measurements were used. Results: We found that the location of the graft in the tibia had an impact on the MRI visibility of the graft at 2-year follow-up. There were significantly more partially or totally invisible grafts if the insertion of the graft was more anterior in the tibia. No association was found between the clinical results and the graft locations. Conclusion: Anterior graft location in the tibia can cause graft invisibility in the MRI 2 years after ACL reconstruction, but this

I would finally like to say something about Gräftåvallen and our hosts, Annica and Tommy Hagström. We decided to take this symposium out of the cities and away from the academic environment and found this charming tiny mountain resort on a mountain slope in the northern Swedish mountains about 20 miles from the nearest village. Annica and Tommy Hagström welcomed us with such a warm hospitality and offered us throughout the week the best of the local mountain specialities such as reindeer, bear and beaver and a variety of mountain fishes. Also the local community greeted us as some very special guests and arranged an afternoon programme at a nearby shieling with goats, sheep, dairy maids, folk music and folk dancing. They also arranged a wonderful concert in their beautiful church from the 12th century. Altogether it was a very special week also outside the lecture room. We, the organizers, experienced this symposium as an unforgettable scientific event thanks to the outstanding contributions of our participants. We hope that these proceedings will convey to the reader something of the excitement felt by the participants during the symposium week.

Additional support was obtained from the Royal Academy of Sciences, the Nordic Institute for Theoretical Atomic Physics (NORDITA), Chalmers University of Technology and Gothenburg University. To arrange a Nobel Symposium on such hot topics is an open invitation for criticism and trouble. The organizers tried their best to select a few topics of current interest in order to generate a strong interaction between participants and to stimulate a good discussion. I would like to express our apologies to all these prominent scientists who could not be invited because of the small format of the Symposium and the planning of the organizers. These Proceedings contain most of the material presented at the Symposium. A few participants found it inconvenient to prepare a full length paper, which would just have been a modified version of material to appear in regular journals. Others might have felt that a conference proceeding be too slow a medium in comparison with e.g. the New York Times. On the whole however these proceedings give a good report of the science discussed during the Symposium. We would like to place on record our sincere thanks to the participants who contributed substantially in the planning by making valuable suggestions about participants and topics. In particular, Bob Schrieffer did a great job in organizing the programme and effectively to run the Symposium. My co-organizers played a crucial role in the planning and during the Symposium week.

    It was in 1986 that we submitted a proposal to organize a Nobel Symposium on the topic "The Birth and Early Evolution of Our Universe", a subject not previously discussed at such a meeting. Our feeling at the time was that it would be appropriate to gather together international expertise on the deep and exciting connections between elementary physics and astrophysics/cosmology. In both these scientific disciplines there are wellknown "standard models"—the Glashow-Weinberg-Salam model of electroweak interactions and the Big-Bang cosmological model. The former model has now been tested to a very high accuracy. Progress in observational cosmology and astrophysics has on the other hand given strong support to the standard Big-Bang model as a realistic framework of cosmological evolution. The interesting fact, of course, is that the two standard models are not independent, and their predictions become interlinked when one considers the early, hot universe. It is now a wonderfully accepted piece of history that the constraint on the number of light neutrinos as obtained from the Big-Bang primordial nucleosynthesis agree very well with recent high-energy laboratory experiments. When our proposal was approved in 1989 we were very happy and honoured to invite a large number of internationally outstanding contributors to take part in the Symposium, almost all of whom were able to participate. It was, however, with deep regret and shock that their sudden deaths prevented us from inviting A Sakharov and Y Zeldovich. Their presence and wisdom was sadly missed. By choosing the beautiful village of Gräftåvallen, outside the town of Östesund, as the location of the Symposium, we hoped to provide a relaxing and stimulating atmosphere and also, possibly, almost twenty hours of sunlight a day for a week. The hosts of Gräftåvallen, Annika and Tommy Hagström, have to be thanked for making our stay both extremely successful and to a memorable experience. Our thanks also go to

    . Similarly, between the groups, there were no differences in pregnancy adaptation with similar trends in cardiovascular function changes from pre-pregnancy to 6 weeks gestation. Whilst this is the first study to investigate preconception and early pregnancy haemodynamic and arterial function in relation to viability, the relatively modest number of miscarriages may not be sufficient to show subtle differences in haemodynamic changes if these were present. This study suggests that pre-pregnancy haemodynamic and arterial function is unlikely to be the causal link between miscarriages and future cardiovascular disease. Our findings suggests that factors other than the presence of a viable embryo drive cardiovascular changes in early pregnancy. This study raises new questions about miscarriages as an independent risk event which predisposes women to increased cardiovascular risk later in life.

    the war Hoyle returned to Cambridge, but kept in close contact with his collaborators. Fred Hoyle was a canny and media-savvy scientist, 40 years before such things were recognized. Martin Rees said after his death '[He] also had other dimensions to his career, his inventiveness and skill as a communicator'. It is hard to realize now the impact that Hoyle's broadcasts had in post-war Britain. His programmes for the BBC on The Nature of the Universe won greater audiences than such unlikely rivals as Bertrand Russell and Tommy Handley. Even today many people recall how they were affected by listening to these broadcasts. Hoyle used one of his broadcasts to ridicule the hot explosion theory. He referred to the idea of a 'big bang as fanciful'. Unfortunately the name stuck, much to Hoyle's chagrin. In the 1950s Hoyle began a fruitful collaboration with Willy Fowler of the California Institute of Technology in Pasadena. Hoyle was interested in the origin of the chemical elements. Hans Bethe, Charles Critchfield and Karl-Frederich von Weizsäcker had calculated in 1939 how stars could turn protons into helium nuclei by nuclear fusion. Part of the Vela supernova remmant, the debris left after the type of massive explosion in which Hoyle predicted that heavy nuclei were formed. (© Royal Observatory, Edinburgh, Anglo-Australian Observatory.) Building on earlier collaboration with Ed Saltpeter, Hoyle used data supplied by Geoffrey and Margaret Burbidge and, working with Fowler, began to piece together how the elements were formed. By looking at very large stars near the end of their lives and examining their chemical composition, they noticed that the abundances of elements almost exactly corresponded to those with a low nuclear capture cross section. Hoyle argued that all of the elements in our bodies had been formed in stars that had been and gone before our solar system had even formed. In their classic paper the elements are produced by three basic methods. The

    for his courses so that his students could take popular courses in other departments, and heavily supported the careers of those faculty members who distinguished themselves as teachers. Ken served on many national committees, was university Ombudsman 1975-1977, was Chairman of the Astronomy Department 1976-1979, and was Dean of the Faculty 1978-1983. He was granted an Emeritus professorship in 1984 and retired in 1986. The affection his colleagues felt for Ken was perhaps best illustrated when a Japanese Post-Doc and life-long friend named his first child Kenichi. Comments received at his death emphasized his ``great competence'' as a scientist; his kindness, generosity, and concern for his students; and his ``thoughtful human values'' and ``great integrity'' as a ``man of character.'' Ken loved music, attending many concerts, playing flute and recorder, and singing in church and senior choirs. He greatly enjoyed hiking, boating, golf, and other outdoor activities, including, in his retirement years, the bicycle and month-long vacations in Kauai and Florida. Ken viewed retirement as a reason to leave university life behind, but not to cease providing service to those about him who needed help. In retirement, Ken volunteered in a variety of activities to assist those less fortunate than himself. In his later years, he engaged in a nearly daily ``hobby'' of writing checks to numerous charities. Ken was preceded in death by his parents, younger brother Sigurd Greisen, older sister Agnita Dupree, first wife of 34 years Elizabeth Chase Greisen, second wife of 20 years Helen Wiltberger Greisen, and stepson Bruce Wiltberger. He is survived by his long-time companion Tommie Bryant of Ithaca; daughter Kathryn Greisen of Columbus, Ohio; son Eric Greisen of Socorro, New Mexico; step children Heather Wiltberger of Marshall, Virginia, Paul Wiltberger of Arlington, Washington, and Lois Wiltberger of Arlington, Massachusetts; and several step-grandchildren.
