    ABSTRACT The genetic study of sandfly populations needs to be further explored given the importance of these insects for public health. Were sequenced the NDH4 mitochondrial gene from populations of Nyssomyia neivai from Doutor Camargo, Lobato, Japira, and Porto Rico, municipalities in the State of Paraná, Brazil, to understand the genetic structure and gene flow. Eighty specimens of Ny. Neivai were sequenced, 20 from each municipality, and 269 base pairs were obtained. A total of 27 haplotypes and 28 polymorphic sites were found, along with a haplotypic diversity of 0.80696 and a nucleotide diversity of 0.00567. Haplotype H5, with 33 specimens, was the most common among the four populations. Only haplotypes H5 and H7 were present in all four populations. The population from Doutor Camargo showed the highest genetic diversity, and only this population shared haplotypes with those from the other municipalities. The highest number of haplotypes was sheared with Lobato which also had the highest number of unique haplotypes. This probably occurred because of constant anthropic changes that happened in the environment during the first half of the twentieth century, mainly after 1998. There was no significant correlation between genetic and geographical distances regarding these populations. However, the highest genetic and geographical distances, and the lowest gene flow were observed between Japira and Porto Rico. Geographical distance is a possible barrier between these municipalities through the blocking of haplotype sharing. PMID:28380111

    Full Text Available Introduction The aim of this study was to identify the blood feeding sources of Nyssomyia intermedia (Ny. intermedia and Nyssomyia neivai (Ny. neivai, which are Leishmania vectors and the predominant sandfly species in the Ribeira Valley, State of São Paulo, Brazil, an endemic area for cutaneous leishmaniasis. Methods Specimens were captured monthly between February 2001 and December 2003 on a smallholding and a small farm situated in the Serra district in the Iporanga municipality. The blood meals of 988 engorged females were tested using the avidin-biotin immunoenzymatic enzyme-linked immunosorbent assay (ELISA. Seven blood meal sources were investigated: human, dog, chicken, bovine, pig, horse and rat. Results The results showed that among the females that fed on one or more blood sources, the respective percentages for Ny. intermedia and Ny. neivai, respectively, were as follows: human (23% and 36.8%, pig (47.4% and 26.4%, chicken (25.7% and 36.8% and dog (3.9% and 0%, and the differences in the blood sources between the two species were statistically significant (p = 0.043. Conclusions Both species had predominant reactivity for one or two blood sources, and few showed reactivity indicating three or four sources. Many different combinations were observed among the females that showed reactivity for more than one source, which indicated their opportunistic habits and eclecticism regarding anthropic environmental conditions.

    The dispersal and survival of the phlebotomines Nyssomyia intermedia and Nyssomyia neivai (both implicated as vectors of the cutaneous leishmaniasis agent) in an endemic area was investigated using a capture-mark-release technique in five experiments from August-December 2003 in municipality of Iporanga, state of São Paulo, Brazil. A total of 1,749 males and 1,262 females of Ny. intermedia and 915 males and 411 females of Ny. neivai were marked and released during the five experiments. Recapture attempts were made using automatic light traps, aspiration in natural resting places and domestic animal shelters and Shannon traps. A total of 153 specimens (3.48%) were recaptured: 2.59% (78/3,011) for Ny. intermedia and 5.35% (71/1,326) for Ny. neivai. Both species were recaptured up to 144 h post-release, with the larger part of them recaptured within 48 h. The median dispersion distances for Ny. intermedia and Ny. neivai, respectively, were 109 m and 100 m. The greatest dispersal range of Ny. intermedia was 180 m, while for Ny. neivai one female was recaptured in a pasture at 250 m and another in a pigsty at 520 m, showing a tendency to disperse to more open areas. The daily survival rates calculated based on regressions of the numbers of marked insects recaptured on the six successive days after release were 0.746 for males and 0.575 for females of Ny. intermedia and 0.649 for both sexes of Ny. neivai. The size of the populations in the five months ranged from 8,332-725,085 for Ny. intermedia males, 2,193-104,490 for Ny. intermedia females, 1,687-350,122 for Ny. neivai males and 254-49,705 for Ny. neivai females.

    Natural infections with Leishmania were found in females of the phlebotomine sand flies Lutzomyia neivai (Pinto) (= Nyssomyia neivai) and Lutzomyia sallesi (Galvão & Coutinho) (= Evandromyia sallesi) (Diptera: Psychodidae) from Lassance, in the Brazilian state of Minas Gerais. Promastigotes were found in the pyloric region of the former species and in the abdominal midgut of the latter species. Insects found to be infected by microscopic examination were macerated in saline solution and inoculated into hamsters. Subsequent analysis by polymerase chain reaction-restriction fragment length polymorphism revealed both isolates to belong to the species Leishmania infantum chagasi Cunha & Chagas.

    Full Text Available In the present work, the hourly activity of Lutzomyia neivai was studied in the southern part of the province of Tucumán, Argentina, in an area of transmission of cutaneous leishmaniasis during two months of higher activity. In addition, the variables that influenced the abundance of Lu. neivai were evaluated. A total of 1,146 individuals belonging to Lu. neivai (97% and Lutzomyia migonei (3% were captured. The hourly activity of Lu. neivai was mainly nocturnal, with a bimodal pattern in both months. In January, the variable that most influenced the abundance of Lu. neivai was the temperature, whereas in April, that variable was humidity. These results may contribute to the design of anti-vectorial control measures at a micro-focal scale.

    Full Text Available The interaction between Leishmania and sand flies has been demonstrated in many Old and New World species. Besides the morphological differentiation from procyclic to infective metacyclic promastigotes, the parasite undergoes biochemical transformations in its major surface lipophosphoglycan (LPG. An upregulation of β-glucose residues was previously shown in the LPG repeat units from procyclic to metacyclic phase in Leishmania (Viannia braziliensis, which has not been reported in any Leishmania species. LPG has been implicated as an adhesion molecule that mediates the interaction with the midgut epithelium of the sand fly in the Subgenus Leishmania. These adaptations were explored for the first time in a species from the Subgenus Viannia, L. (V. braziliensis with its natural vectors Lutzomyia (Nyssomyia intermedia and Lutzomyia (Nyssomyia whitmani. Using two in vitro binding techniques, phosphoglycans (PGs derived from procyclic and metacyclic parasites were able to bind to the insect midgut and inhibit L. braziliensis attachment. Interestingly, L. braziliensis procyclic parasite attachment was ∼11-fold greater in the midgut of L. whitmani than in L. intermedia. The epidemiological relevance of L. whitmani as a vector of American Cutaneous Leishmaniasis (ACL in Brazil is discussed.

    Full Text Available A biologia reprodutiva de Dipsas neivai Amaral, 1923 e Dipsas catesbyi (Sentezen, 1796 foi estudada através da dissecção de 261 espécimes de D. neivai e 222 de D. catesbyi. Em D. neivai o macho amadurece com menor tamanho do que a fêmea, ocorrendo o oposto em D. catesbyi. Em ambas as espécies a fêmea atinge maior tamanho corporal que o macho. O tamanho da ninhada variou de um a oito ovos em D. neivai e de um a seis em D. catesbyi, não estando correlacionado com o tamanho da fêmea na última. O ciclo reprodutivo em ambos machos e fêmeas é contínuo, com vitelogênese e espermatogênese ocorrendo ao longo do ano todo. Em Dipsas neivai, a cópula nas fêmeas é dissociado da vitelogênese. D. neivai e D. catesbyi são sintópicas, e reproduzem no mesmo período do ano, o que possivelmente está relacionado à disponibilidade contínua de presas e à pouca variação climática no sudeste da Bahia.The reproductive biology of Dipsas neivai Amaral, 1923 and Dipsas catesbyi (Sentzen, 1796, was studied by dissecting 261 specimens of D. neivai and 222 of D. catesbyi. In D. neivai males mature at smaller body size than females, and in D. catesbyi the opposite was observed. The females were larger than males in both species. The clutch size ranged from one to eight in D. neivai, and one to six in D. catesbyi, but it is not correlated with female length in the last one. Reproductive cycles in both males and females are aseasonal, with vitelogensis and spermatogenesis occurring throughout the year. The couple in females of D. neivai is dissociated from the vitellogenesis. D. neivai and D. catesbyi are syntopic and reproduce in the same time of the year, which is possibly related to the continuous availability of prey and little climate variation in southern Bahia.

    Full Text Available The period of resistance to starvation and the loss of weight until death of Rhodnius neivai in all stages of development were studied. Work was based on experiments conducted under controlled laboratory conditions. One hundred specimens of each nymphal instar were observed: 50 were fed on chicken and 50 on rabbit. Adult females and males were kept together and fed on each host. All bugs were weighed weekly until death. Laid eggs were collected weekly and observed during five weeks to obtain hatchability. Resistance to starvation was similar with both hosts and increased with the evolutionary stage, excepting the 5th nymphal instar and adults. With both hosts, loss of weight was abrupt in the first week and steady in the following weeks. In adults, on the first weeks after eating, there was little or no mortality, after which mortality increased rapidly with the starving time. Reproductive output was higher in the bugs fed on rabbit. R. neivai is among the least resistant triatomine species.

    Full Text Available The dispersal pattern of the sand fly Lutzomyia neivai was studied through mark-release-recapture experiments in an American cutaneous leishmaniasis endemic rural area in Southeastern Brazil. Over 6500 specimens were marked with fluorescent powder and released in forest edge and peridomicile habitats from August to November 1999, February and April 2000. Recapture attempts were made using Shannon and CDC traps up to eight successive nights after releases. A total of 493 (7.58% specimens were recaptured. The number of recaptured males and females of L. neivai in CDC traps was not affected by the distance between the trap and the release points. Approximately 90% of males and females recaptured in CDC traps were caught up to 70 m from the release points. The maximum female flight range recorded was 128 m. The average flight range per day was less than 60 m for males and females. Of the flies released in forest edge, approximately 16% of the recaptured females were caught in Shannon traps in the peridomicile habitat. The results indicate that the movements of L. neivai are spatially focal and the possibility of dispersion from forest to peridomicile habitat may be an important way of contracting leishmaniasis in dwellings.

    Full Text Available On the southwest Pacific Coast of Colombia, a field study was initiated to determine the human-vector association between Anopheles (Kerteszia neivai and fishermen, including their nearby houses. Mosquitoes were collected over 24-h periods from mangrove swamps, marshlands and fishing vessels in three locations, as well as in and around the houses of fishermen. A total of 6,382 mosquitoes were collected. An. neivai was most abundant in mangroves and fishing canoes (90.8%, while Anopheles albimanus was found indoors (82% and outdoors (73%. One An. neivai and one An. albimanus collected during fishing activities in canoes were positive for Plasmodium vivax , whereas one female An. neivai collected in a mangrove was positive for P. vivax . In the mangroves and fishing canoes, An. neivai demonstrated biting activity throughout the day, peaking between 06:00 pm-07:00 pm and there were two minor peaks at dusk and dawn. These peaks coincided with fishing activities in the marshlands and mangroves, a situation that places the fishermen at risk of contracting malaria when they are performing their daily activities. It is recommended that protective measures be implemented to reduce the risk that fishermen will contract malaria.

Area of hostels for tourists who visit the Parque Estadual do Alto Ribeira (PETAR, state of São Paulo, Brazil. The study characterizes some ecological aspects of the phlebotomine fauna in an endemic area of cutaneous leishmaniasis (CL situated in the Serra district, Iporanga municipality where the hostels for tourists visiting the PETAR are located. Captures were undertaken on a smallholding and a small farm situated near the hostels, monthly between January/2001 and December/2003 with automatic light traps (ALT in pigsty, hen-house and veranda of a domicile at the two sites, and in peridomicile of the small farm also with black/white Shannon traps. With the ALT a total of 87,224 phlebotomines representing 19 species and also two hybrids of Nyssomyia intermedia (Lutz & Neiva and Nyssomyia neivai (Pinto and two anomalous specimens were captured. The standardized index species abundance was for Ny. intermedia = 1.0 and Ny. neivai = 0.935. The highest frequencies of the smallholding occurred in the pigsty, the Williams' mean/capture for Ny. intermedia being 63.7 specimens and for Ny. neivai 29.2, and on the small farm, in the hen-house, Ny. intermedia 402.6 and Ny. neivai 116.2. A total of 863 phlebotomines (Ny. intermedia: 75.4%; Ny. neivai: 24.3% were captured with black/white Shannon traps; females of both species being predominant in the white trap. The high frequencies of Ny. intermedia and Ny. neivai, both implicated in CL transmission, indicate the areas presenting risk of the disease.

    Consumption of dry beans has been relatively flat over the last decade. Creating new bean products may increase the consumption of beans and allow more consumers to obtain the health benefits of beans. In this study, pinto, navy and black beans were milled and the resulting flours extruded into puffs. Unflavored extruded puffs were evaluated by untrained panelists using a hedonic scale for appearance, flavor, texture and overall acceptability. The compositions of raw flours and extrudates were characterized. Sensory results indicated that all beans met or exceeded the minimum requirement for acceptability. Overall acceptability of navy and pinto beans was not significantly different, while acceptability of black bean puffs was significantly lower. Total protein (198-217 g kg(-1)) in extrudates was significantly different among the three beans. Total starch ranged from 398 to 406 g kg(-1) and was not significantly different. Resistant starch, total extractable lipid and raffinose contents were significantly reduced by extrusion. Extrusion did not affect crude fiber and phytic acid contents. The minimal effects on protein and fiber contents, the significant reduction in raffinose content and the acceptability of the unflavored extruded puffs support using various bean flours as ingredients in extruded puffed products. © 2014 Society of Chemical Industry.

    Full Text Available Abstract Background Acoustic signals are part of the courtship of many insects and they often act as species-specific signals that are important in the reproductive isolation of closely related species. Here we report the courtship songs of the sand fly Lutzomyia (Nyssomyia intermedia, one of the main vectors of cutaneous leishmaniasis in Brazil. Findings Recordings were performed using insects from three localities from Eastern Brazil: Posse and Jacarepaguá in Rio de Janeiro State and Corte de Pedra in Bahia State. The three areas have remnants of the Brazilian Atlantic forest, they are endemic for cutaneous leishmaniasis and L. intermedia is the predominant sand fly species. We observed that during courtship L. intermedia males from all populations produced pulse songs consisting of short trains. No significant differences in song parameters were observed between the males of the three localities. Conclusions L. intermedia males produce acoustic signals as reported for some other sand flies such as the sibling species of the Lutzomyia longipalpis complex. The lack of differences between the males from the three localities is consistent with previous molecular studies of the period gene carried out in the same populations, reinforcing the idea that L. intermedia is not a species complex in the studied areas and that the three populations are likely to have similar vectorial capacities.

    Lutzomyia fraihai (Martins, Falcão & Silva 1979), described from Três Braços municipality (Bahia state, Brazil), is closely related to Nyssomyia yuilli yuilli (Young & Porter, 1972), described from Rio Anori, Antioquia, Colombia. The former species, despite the morphological differences reported by its authors, was included as a junior synonym of Ny. yuilli yuilli, and this status has been accepted by sand fly-taxonomists. However, we had an opportunity to examine both taxa, and a clear difference was noted in their male genitalia. In this study, the morphometric/morphologic characters of specimens that had been identified as Ny. yuilli yuilli from different localities (Brazil, Peru, Colombia, Bolivia) and type material of both Ny. yuilli yuilli and Lu. fraihai were analyzed. The results revealed that males from Brazil (Bahia, Acre, Pará, and Rondônia states) and Peru present statistically significant differences in the ratio between paramere rectangular and digitiform areas as well as for the cercus length and width of the aedeagal ducts tips, when compared with the type specimens of Ny. yuilli yuilli, but are statistically similar to those characters of Lu. fraihai However, females of the two species are indistinguishable. Thus, based on the male morphology, Ny. fraihai STAT REV N COM: was resurrected from the synonymy of Ny. yuilli yuilli. The specimens from the Atlantic forest biome and the Amazon biome in Brazil, Peru, and Bolivia in fact belong to Ny. fraihai This species presents a cis-Andean distribution, while Ny. yuilli yuilli has been found in both Andean and Trans-Andean areas. © The Authors 2016.

The texturized high protein fraction (THPF) was then milled to obtain flour, and combined with wheat flour at 5, 10, and 15% levels to make bread. The air-classification process produced flour with high concentration of lipids and phytic acid in the protein-rich fraction. However, extrusion significantly reduced hexane extractable lipid and phytic acid. However, the reduction observed may simply indicate a reduction in recovery due to bind with other components. Total protein and lysine contents in composite flours increased significantly as THPF levels increased in composite flour. Bread made with 5% THPF had 48% more lysine than the 100 % wheat flour (control). The THPF helped to maintain dough strength by reducing mixing tolerance index (MTI), maintaining dough stability and increasing departure time on Farinograph. Bread loaf volume was significantly reduced above 5% THPF addition. THPF increased water absorption causing an increase in bread weights by up to 6%. Overall, loaf quality deteriorated at 10 and 15% THPF levels while bread with 5% THPF was not significantly different from the control. These results support the addition of 5% THPF as a means to enhance lysine content of white pan bread.

    Full Text Available Changes in life tables of Rhodnius neivai due to variations of environmental temperature were studied, based on nine cohorts. Three cohorts were kept at 22°C, three at 27°C and three at 32°C. Cohorts were censused daily during nymphal instars and weekly in adults. Nine complete horizontal life tables were built. A high negative correlation between temperature and age at first laying was registered (r=-0,84. Age at maximum reproduction was significantly lower at 32°C. Average number of eggs/female/week and total eggs/female on its life time were significantly lower at 22°C. Total number of egg by cohort and total number of reproductive weeks were significantly higher at 27°C. At 32°C, generational time was significantly lower. At 27°C net reproductive rate and total reproductive value were significantly higher. At 22°C, intrinsic growth, finite growth and finite birth rates were significantly lower. At 22°C, death instantaneous rate was significantly higher.

    Full Text Available The aim of this study was to identify the behavioral response in growth and physiology on three bean varieties under irrigation and drought. The study was conducted in 2014 at the experimental campus from the Autonomous University of Chapingo, Regional University Unit of the Arid Zones, Durango, Mexico. A randomized block design with three replications in a split plot arrangement was used. The plots were the soil moisture contents: favorable, near to Field Capacity (FC: 22-26% and unfavorable, near to Permanent Wilting Point (PWP: 16-20%; subplots were varieties of beans: Pinto Centauro, Pinto Americano, and Pinto Saltillo. The variety Pinto Centauro had the greatest plant height (10.2 cm, vegetation cover (155.1 cm2, and dry matter production per plant (5.2 g and, physiologically, it showed an outstanding water use efficiency (15.8 μmol CO2: μmol H20. The variety Pinto Americano was the most stable in growth and development when changing from the favorable moisture condition (CC to the hydric stress condition (PWP, which makes it more viable under restrictive water availability conditions, but also more susceptible to root rot, associated to soil pathogens.

    Full Text Available In order to evaluate the benefits of maize, pinto bean and naked pumpkin triple cropping, an experiment was carried out as a randomized complete block design with three replications at Faculty of Agricultural Science, University of Guilan, Rasht, Iran in 2012. The treatments consisted of maize, pinto bean and naked pumpkin sole cropping (100, 75 and 50% of conventional densities, maize – pinto bean and maize – pumpkin double cropping (100-100%, 75-75% and 50-50%, and maize-pinto bean-pumpkin triple cropping (100-100-100%, 75-75-75% and 50-50-50%. The highest and lowest forage fresh weights were obtained in triple cropping system with high density and sole cropping systems with low density, respectively. In double cropping systems, the maize-pumpkin out-yielded the maize-pinto bean in terms of fresh weight. The relative crowding coefficient, competitive ratio and aggressivity of maize in double cropping of maize-pinto bean and naked pumpkin in double cropping of maize-naked pumpkin were dominant. In triple cropping systems, while maize and naked pumpkin were comparable, but both of the latter crops were dominant over pinto bean. Land Equivalent Ratio (LER for double and triple cropping was greater than one, revealing the profitability of double and triple cropping systems on sole cropping. According to the LER, the cropping systems can be ranked as follows: triple cropping > double cropping maize/pinto bean > double cropping maize/pumpkin

    Full Text Available Most foods are considered functional in terms of providing nutrients and energy to sustain daily life, but dietary systems that are capable of preventing or remediating a stressed or diseased state are classified as functional foods. Dry beans (Phaseolus vulgaris L. contain high levels of chemically diverse components (phenols, resistance starch, vitamins, fructooligosaccharides that have shown to protect against such conditions as oxidative stress, cardiovascular disease, diabetes, metabolic syndrome, and many types of cancer, thereby positioning this legume as an excellent functional food. Moreover, the United States has a rich dry bean history and is currently a top producer of dry beans in the world with pinto beans accounting for the vast majority. Despite these attributes, dry bean consumption in the US remains relatively low. Therefore, the objective of this manuscript is to review dry beans as an important US agricultural crop and as functional food for the present age with an emphasis on pinto beans.

    Full Text Available A lírica de Claudia Roquette-Pinto encontra no ambiente do jardim, simulacro miniaturizado do mundo natural, as imagens que compõem a representação simbólica do conflito surgido entre o eu e o mundo, e intensa reflexão metapoética. As imagens recorrentes da queda, da flor, da escuridão e do corpo que enformam a materialidade simbólica de Roquette-Pinto revelam uma lírica constituída em uma zona de transição, estabelecida entre saturação da ordem social orientada pelo aproveitamento racional do mundo e pela dominação da natureza, e a insurgência pós-moderna de uma ordem ecológica, na qual se privilegia a fruição mais livre do presente. A abordagem metodológica escolhida para adentrar a lírica de Claudia Roquette-Pinto orienta-se a partir da teoria das estruturas antropológicas do imaginário proposta por Gilbert Durand conjuntamente com as reflexões sobre a sociedade contemporânea presentes na obra do sociólogo Michel Maffesoli. Na primeira e segunda seção do artigo, apresentam-se brevemente considerações sobre o imaginário e o estruturalismo figurativo de Gilbert Durand; na terceira seção analisa-se um pequeno recorte da lírica de Roquette-Pinto.

    Leishmaniasis represents an important public health problem in Brazil. The continuous process of urbanization and expansion of human activities in forest areas impacts natural habitats, modifying the ecology of some species of Leishmania, as well as its vectors and reservoirs and, consequently, changes the epidemiological pattern that contributes to the expansion of American cutaneous leishmaniasis in Brazil. Here, we discuss Lutzomyia (Nyssomyia) whitmani, the main vector of ACL, transmitting two dermotropic Leishmania species including Leishmania (Viannia) braziliensis and Leishmania (V.) shawi. We used the maximum entropy niche modelling approach (MaxEnt) to evaluate the environmental suitability of L. (N.) whitmani and the transmission of ACL in Brazil, in addition to designing models for a future scenario of climate change. MaxEnt was used under the "auto-features" mode and the default settings, with 100-fold repetition (bootstrap). The logistic output was used with higher values in the habitat suitability map, representing more favourable conditions for the occurrence of L. (N.) whitmani and human cases of ACL. Two models were developed: the Lutzomyia (N.) whitmani model (LWM) and the American cutaneous leishmaniasis model (ACLM). LWM identified the species "preferential habitat" included regions with moderate annual precipitation (AP) between 1000-1600 mm, intermediate vegetation density (NDVI) values, mean temperature of the coldest quarter (MTCQ), between 15-21 °C, and annual mean temperature (AMT), between 19-24 °C. ACLM indicates that ACL is strongly associated with areas of intermediate density vegetation, areas with AP between 800-1200 mm, MTCQ above 16 °C and AMT below 23 °C. The models generated for L. (N.) whitmani and ACL indicated a satisfactory predictive capacity. Future projections of LWM indicate an expansion of climatic suitability for L. (N.) whitmani for the northern and southern regions of Brazil. Future projections of ACL indicate the

    The objective of this study was develop a snack product based on fried beans. For this purpose, three bean varieties were used: Pinto 114, Suave 85 and Tórtola Inia. The beans were treated with two soaking solutions, EDTA disodium salt and a mixture of NaOH/water, to determine if they had some effect on the product's final quality. On the other hand, before the beans were fried, some grains were given thermal treatment (blanched), leaving the other ones without this process (raw); this also had an effect on the final quality of the fried beans. Physical, chemical and sensory characteristics of the final fried products were determined. For three beans varieties, the blanched products had higher water content, higher oil absorption, lower protein content and larger water activity. The soaking solutions had no effect on the quality of manufactured products. The sensory analysis determined that the best treatment for Pinto 114 and Tórtola Inia was NaOH/water-raw grain, and EDTA raw grain for Suave 85.

    Full Text Available Lutzomyia (Nyssomyia whitmani s.l.is the main vector of cutaneous leishmaniasis in state of Mato Grosso, but little is known about environmental determinants of its spatial distribution on a regional scale. Entomologic surveys of this sand fly species, conducted between 1996 and 2001 in 41 state municipalities, were used to investigate the relationships between environmental factors and the presence of the species, and to develop a spatial model of habitat suitability. The relationship between averaged CDC light trap indexes and 15 environmental and socio-economic factors were tested by logistic regression (LR analysis. Spatial layers of deforestation tax and the Brazilian index of gross net production (IGNP were identified as significant explanatory variables for vector presence in the LR model, and these were then overlaid with habitat maps. The highest habitat suitability in 2001 was obtained for the heavily deforested areas in the Central-North, South, East, and Southwest of Mato Grosso, particularly in municipalities with lower IGNP values.

    Nelson, M.; Dempster, W. F.; Allen, J. P.; Silverstone, S.; Alling, A.; van Thillo, M.

    An experiment utilizing cowpeas ( Vigna unguiculata L.), pinto beans ( Phaseolus vulgaris L.) and Apogee ultra-dwarf wheat ( Triticum sativa L.) was conducted in the soil-based closed ecological facility, Laboratory Biosphere, from February to May 2005. The lighting regime was 13 h light/11 h dark at a light intensity of 960 μmol m -2 s -1, 45 mol m -2 day -1 supplied by high-pressure sodium lamps. The pinto beans and cowpeas were grown at two different planting densities. Pinto bean production was 341.5 g dry seed m -2 (5.42 g m -2 day -1) and 579.5 dry seed m -2 (9.20 g m -2 day -1) at planted densities of 32.5 plants m -2 and 37.5 plants m -2, respectively. Cowpea yielded 187.9 g dry seed m -2 (2.21 g m -2 day -1) and 348.8 dry seed m -2 (4.10 g m -2 day -1) at planted densities of 20.8 plants m -2 and 27.7 plants m -2, respectively. The crop was grown at elevated atmospheric carbon dioxide levels, with levels ranging from 300-3000 ppm daily during the majority of the crop cycle. During early stages (first 10 days) of the crop, CO 2 was allowed to rise to 7860 ppm while soil respiration dominated, and then was brought down by plant photosynthesis. CO 2 was injected 27 times during days 29-71 to replenish CO 2 used by the crop during photosynthesis. Temperature regime was 24-28 °C day/deg 20-24 °C night. Pinto bean matured and was harvested 20 days earlier than is typical for this variety, while the cowpea, which had trouble establishing, took 25 days more for harvest than typical for this variety. Productivity and atmospheric dynamic results of these studies contribute toward the design of an envisioned ground-based test bed prototype Mars base.

    Full Text Available Vector borne diseases are susceptible to climate change because distributions and densities of many vectors are climate driven. The Amazon region is endemic for cutaneous leishmaniasis and is predicted to be severely impacted by climate change. Recent records suggest that the distributions of Lutzomyia (Nyssomyia flaviscutellata and the parasite it transmits, Leishmania (Leishmania amazonensis, are expanding southward, possibly due to climate change, and sometimes associated with new human infection cases. We define the vector's climatic niche and explore future projections under climate change scenarios. Vector occurrence records were compiled from the literature, museum collections and Brazilian Health Departments. Six bioclimatic variables were used as predictors in six ecological niche model algorithms (BIOCLIM, DOMAIN, MaxEnt, GARP, logistic regression and Random Forest. Projections for 2050 used 17 general circulation models in two greenhouse gas representative concentration pathways: "stabilization" and "high increase". Ensemble models and consensus maps were produced by overlapping binary predictions. Final model outputs showed good performance and significance. The use of species absence data substantially improved model performance. Currently, L. flaviscutellata is widely distributed in the Amazon region, with records in the Atlantic Forest and savannah regions of Central Brazil. Future projections indicate expansion of the climatically suitable area for the vector in both scenarios, towards higher latitudes and elevations. L. flaviscutellata is likely to find increasingly suitable conditions for its expansion into areas where human population size and density are much larger than they are in its current locations. If environmental conditions change as predicted, the range of the vector is likely to expand to southeastern and central-southern Brazil, eastern Paraguay and further into the Amazonian areas of Bolivia, Peru, Ecuador

Most radionuclides, with the exception of 3 H and tot U, in soil from LAC were detected in significantly higher concentrations (p -1 . This dose was below the International Commission on Radiological Protection permissible dose limit (PDL) of 100 mrem y -1 from all pathways; however, the addition of other internal and external exposure route factors may increase the overall dose over the PDL.

    Full Text Available ABSTRACT The objective was to evaluate the effect of three levels of cull pinto beans (CPB; Phaseolus vulgaris on ruminal fermentation, kinetics, and nutrient digestibility in hair lambs. Six cannulated lambs averaging 56.6±3.8 kg were used and were randomly assigned to one of three treatments. Treatments were: 0.0 kg kg−1 of CPB in the supplement (control; 0.25 kg kg−1 of CPB in the supplement (CB25; and 0.40 kg kg−1 of CPB in the supplement (CB40. Dry matter intake, ruminal pH, NH3, and volatile fatty acid (VFA concentration, methane production, Kp (passage rate, MRT (mean retention time, and digestibility of dry matter, crude protein, and neutral detergent fiber were evaluated. Data were analyzed in a Latin square design, repeated in line, by MIXED procedure of SAS. Estimates used for Kp and MRT were obtained by a non-linear regression model (PROC NLIN. Dry matter intake was reduced by supplementation of CPB. No differences were found in ruminal pH or ruminal NH3. During the trial, differences were found for ruminal VFA concentration (mM, which were greater for the CB25 group. The propionate:acetate ratio was greater for the CB40 treatment. Methane production (mM/m differed among treatments, but it was the greatest for the CB40 group. Passage rate (kg kg−1/h and MRT (h were similar among treatments and the digestibility (kg kg−1 of dry matter, crude protein, and neutral detergent fiber was not different among treatments. The inclusion of 0.25 kg kg−1 of CPB in the diet of hair lambs allows for appropriate nutrient digestion without affecting Kp and MRT and increases the molar proportion of the ability of VFA to maintain acetate:propionate ratio without increasing methane production.

  2. Carbon dioxide dynamics of combined crops of wheat, cowpea, pinto beans in the Laboratory Biosphere closed ecological system

    A mixed crop consisting of cowpeas, pinto beans and Apogee ultra-dwarf wheat was grown in the Laboratory Biosphere, a 40 m 3 closed life system equipped with 12,000 W of high pressure sodium lamps over planting beds with 5.37 m 2 of soil. Similar to earlier reported experiments, the concentration of carbon dioxide initially increased to 7860 ppm at 10 days after planting due to soil respiration plus CO 2 contributed from researchers breathing while in the chamber for brief periods before plant growth became substantial. Carbon dioxide concentrations then fell rapidly as plant growth increased up to 29 days after planting and subsequently was maintained mostly in the range of about 200-3000 ppm (with a few excursions) by CO 2 injections to feed plant growth. Numerous analyses of rate of change of CO 2 concentration at many different concentrations and at many different days after planting reveal a strong dependence of fixation rates on CO 2 concentration. In the middle period of growth (days 31-61), fixation rates doubled for CO 2 at 450 ppm compared to 270 ppm, doubled again at 1000 ppm and increased a further 50% at 2000 ppm. High productivity from these crops and the increase of fixation rates with elevated CO 2 concentration supports the concept that enhanced CO 2 can be a useful strategy for remote life support systems. The data suggests avenues of investigation to understand the response of plant communities to increasing CO 2 concentrations in the Earth's atmosphere. Carbon balance accounting and evapotranspiration rates are included.

    Proanthocyanidins and flavonoids were isolated and identified from seed coats of two aged and nonaged pinto bean lines: 1533-15 and CDC Pintium. The seed coat of 1533-15 darkens slowly and never darkens to the same extent as CDC Pintium. Analysis of the overall level of proanthocyanidins using a vanillin assay demonstrated that aged and nonaged seed coats of CDC Pintium had significantly higher levels of proanthocyanidins than aged and nonaged 1533-15 seed coats. Aged and nonaged seed coats of both lines were found to contain one main flavonol monomer, kaempferol, and three minor flavonols, kaempferol 3-O-glucoside, kaempferol 3-O-glucosylxylose, and kaempferol 3-O-acetylglucoside. These compounds were identified by NMR and ESI-MS analysis (except for kaempferol 3-O-acetylglucoside, which was tentatively identified only by ESI-MS analysis) and quantified using HPLC-DAD. The combined concentrations of all the kaempferol compounds in seed coats of CDC Pintium were significantly higher than in seed coats of 1533-15, and the combined contents did not change after aging. The content of kaempferol decreased nearly by half in the seed coats of CDC Pintium after aging, whereas no significant change was observed in the seed coats of 1533-15. Proanthocyanidin fractions from both lines, aged and nonaged, were subjected to LC-MS/MS analysis and found to be composed primarily of procyanidins. Procyanidins in the seed coats were predominantly polymers with the degree of polymers higher than 10. The proportion of these polymers decreased after aging, while that of the low-molecular-weight procyanidins increased. A catechin-kaempferol adduct was tentatively identified in both lines by LC-MS/MS, and the concentration increased in the seed coats after aging.

    The influence of pinto bean flour and processing moisture on the physical properties and in vitro digestibility of rice-bean extrudates has been investigated. Brown rice: pinto bean flour (0%, 15%, 30%, and 45% bean flour) were extruded under 5 moisture conditions (17.2%, 18.1%, 18.3%, 19.5%, and 20.1%). Physical properties [bulk density, unit density, radial expansion, axial expansion, overall expansion, specific volume, hardness, color, water solubility index, and water absorption index] and in vitro starch and protein digestibilities were determined. Increasing bean flour and processing moisture increased density and hardness while decreasing expansion. Rapidly digestible starch decreased and resistant starch increased as bean substitution and processing moisture increased. In vitro protein digestibility increased with increasing bean flour or with decreasing processing moisture. Incorporating bean flour into extruded snacks can negatively affect physical attributes (hardness, density, and expansion) while positively affecting in vitro starch (decrease) and protein (increase) digestibilities.

    Full Text Available Mitomycin C (MC, N-hydroxyurea (HU and actinomycin D (AD inhibit tumour formation on the primary leaves of Pinto beans. Agrobacterium tumefaciens was inoculated into bean leaves with application of the above named inhibitors at various times. It was found that MC action is strongest during inoculation and immediately after it, the maximal effect of HU take place within 12 h after inoculation, whereas the antitumour action of AD starts as late as 12 h after leaf inoculation. In view of the different degree of susceptibility of bacteria and plant cells to the inhibitors applied, the above described results allowed to distinguish three critical periods in the process of tumour formation in the tested host-pathogen system.

    Full Text Available Introduction Drought or water deficit stress is the most important environmental factor which has severe negative impacts on crop yields, especially when the water stress occurs in the flowering stage. Iran is located in arid and semi-arid areas, therefore, attention to the effects of water deficit stress in different stages of plants growth seems necessary. Bean (Phaseolus vulgaris L. is one of the most important legumes that has a major contribution to human diet and provides an important part of the human protein. According to studies, cultivation areas of legumes in Iran are about 97300 hectares and its total production is about 208350 tons of grain. Bean is a fast-growing plant (Tran and Singh, 2002, thus soil water must be sufficiently available to ensure its desirable growth and yield. The aim of this study was to investigate the effect of drought stress on yield and yield components of some pinto bean (Phaseolus vulgaris L. cultivated in Zanjan province. Materials and methods An experiment was conducted as spilt plot based on randomized complete block design with four replications in Zanjan university research farm. Irrigation levels (control and drought stress and genotypes (Local khomein, Sadri, Ks21193 and Ks21189 were set in the main and subplot, respectively. Water deficit stress was applied during flowering stage (50% of the plants were at anthesis. Sampling was performed to measure yield and yield components at the end of the growth period and final maturity. In this experiment number of pod per Plant, numberof grain per pod, 100 grain weight, grain yield, biological yield and harvest index were measured. Results and Discussion In this experiment it was observed that drought stress, genotype and interact irrigation×genotyps were significantly for all traits except biological yield. Drought stress reduced number of pod perplant, number of grain per pod, 100 grain weight, grain yield, biological yield and Harvest Index. Results

    Full Text Available INTRODUCTION: An epidemiological study was undertaken to identify determinant factors in the occurrence of American cutaneous leishmaniasis in areas under the influence of hydroelectric plants in Paranapanema river, State of Paraná, Brazil. The ecological aspects of the phlebotomine fauna were investigated. METHODS: Sandflies were sampled with automatic light traps from February 2004 to June 2006 at 25 sites in the urban and rural areas of Itambaracá, and in Porto Almeida and São Joaquim do Pontal. RESULTS: A total of 3,187 sandflies of 15 species were captured. Nyssomyia neivai predominated (34.4%, followed by Pintomyia pessoai (32.6%, Migonemyia migonei (11.6%, Nyssomyia whitmani (8.8%, and Pintomyia fischeri (2.7%, all implicated in the transmission of Leishmania. Males predominated for Ny. neivai, and females for the other vector species, with significant statistical differences (p < 0.001. Nyssomyia neivai, Pi. pessoai, Ny. whitmani, Brumptomyia brumpti, Mg. migonei, and Pi. fischeri presented the highest values for the Standardized Species Abundance Index (SSAI. The highest frequencies and diversities were found in the preserved forest in Porto Almeida, followed by forests with degradation in São Joaquim do Pontal and Vila Rural. CONCLUSIONS: Sandflies were captured in all localities, with the five vectors predominating. Ny. neivai had its highest frequencies in nearby peridomestic environments and Pi. pessoai in areas of preserved forests. The highest SSAI values of Ny. neivai and Pi. pessoai reflect their wider dispersion and higher frequencies compared with other species, which seems to indicate that these two species may be transmitting leishmaniasis in the area.

    Full Text Available Dois experimentos foram conduzidos, para avaliar hidratantes em pintos oriundos de matrizes, em início de vida produtiva. O primeiro experimento estudou o efeito de hidratante comercial, na fase pré-alojamento, em pintos oriundos de matrizes com 25 semanas de idade, submetidos a dois intervalos entre nascimento e alojamento (0 e 48 horas; o agente não apresentou qualquer efeito favorável sobre a desidratação, a mortalidade e o desempenho até 21 dias. No segundo experimento, foi utilizado o bicarbonato de sódio como hidratante. A solução foi fornecida, durante 24 horas, a pintos oriundos de matrizes com 27 semanas de idade, após 0, 24 e 48 horas de intervalo entre nascimento e alojamento. Foi observada melhora na integridade do intestino, representada pelo aumento na densidade intestinal e peso do órgão com a suplementação eletrolítica. O aumento no intervalo entre nascimento e alojamento diminuiu o saco vitelino. Em ambos os experimentos, o aumento no intervalo entre o nascimento e o alojamento aumentou a desidratação e a mortalidade das aves, mas propiciou melhora no desempenho aos 21 dias, não tendo sido observados efeitos positivos dos hidratantes testados.Two experiments were carried out to evaluate hydrating agents to newly hatched chicks from breeders in early production life. The first experiment studied the effect of commercial hydrating agents in pre-lodging phase in chicks from breeders with 25 weeks of age and submitted to two intervals between hatching and lodging (0 and 48 hours.

    Full Text Available Mercedes Pinto’s itinerary took her from the Canary Islands, where she was born, to Mexico, after a passage through Uruguay. She first met success through her writings and cultural activities, and was then forgotten. However, her book –published in Montevideo in 1926– was adapted for the cinema by Luis Buñuel in 1952, and the film gave new life to this autobiographical “novel” He. If self-fiction prevails in the literary work, with the clear commitment of a feminist who takes a stand in favour of freedom –the freedom to divorce in that case–, in Buñuel’s Mexican film the study of the clinical case of paranoia acquires a new form of complexity. The attack on a parasitic bourgeoisie is united to the subversion of the melodramatic genre, with a false happy end which distorts established codes and lets the principle of doubt impose itself. In the same way the exploration of sexual roles, heir to the surrealistic trend, is devoid of any manichean simplification and stands out as a fascinating object for any hermeneutic approach.Mercedes Pinto, cuya trayectoria se desarrolló desde Canarias, su tierra de nacimiento, hasta México, pasando por Uruguay, conoció el éxito por sus escritos y actividades culturales y luego quedó sumida en el olvido. Sin embargo, la adaptación de su “novela” autobiográfica Él (Montevideo, 1926 a la gran pantalla por Luis Buñuel en 1952, le deparó otra vida al libro. Si en la obra literaria prevalece la autoficción y su claro compromiso feminista a favor del divorcio, adquiere nueva complejidad en la película mexicana de Buñuel el estudio del caso clínico de la paranoia. Al ataque a una burguesía parasitaria se une una subversión del género del melodrama, cuyo falso final feliz pervierte los códigos establecidos, dejando que se imponga el principio de duda. Asimismo, la exploración de los roles sexuales, heredera de la corriente surrealista, rehúye toda simplificación maniquea y se

    En forma espontánea y por unanimidad ha querido el Comité Permanente de Biblioteca y Publicaciones que un compartido relato de sus labores realizadas y prospecciones anheladas en este lapso bienal quede consignado en la edición No. 22 de MEDICINA.

    En efecto, el Comité Editorial tuvo como principal objetivo en este período la publicación de la Revista, habiendo recibido ininterrumpidamente de la dinámica y eficiente Junta Directiva saliente, estímulo, autonomía y respaldo a su modesta labor.

    Obligante finalidad para sus integrantes fue el desempeño de su actividad para conservar la publicación en su categoría genuinamente representativa del tradicional prestigio que ha caracterizado al órgano informativo de la Academia desde su inicio en el siglo pasado.

    El ejercicio de esta responsabilidad editorial no estuvo exento de amenazante crisis que pudo ser superada gracias a la asociación de fuerzas del Comité, Junta Directiva e ITALMEX, lo que nos ha dado impulso para planear y ejecutar un programa completo de acción destinado a lograr el incremento y soporte de un alto nivel científico para “MEDICINA” en sus copiosas ediciones de seleccionada repartición y amplia circulación.

    La intención de nutrir la Revista preferente ‘pero no exclusivamente’ con talento nacional, solo podremos cumplirla a cabalidad en la medida en que nuestros académicos se solidaricen, no con el Comité, -de efímera figuración- sino con la Revista misma, de vigencia perenne y cuyo prestigio nos concierne a todos tarde o temprano. Si aceptáramos la motivación y miráramos desprevenidamente hacia “MEDICINA” podríamos asumir una actitud consecuente con la intención inicial de cuando solicitamos nuestro ingreso a la Academia y, por ende, con este generoso rasgo espiritual su capacidad productiva en potencia se dirigiría a abastecer debidamente los requerimientos de una oportuna y suficiente publicación.

    El Comité Editorial propicia para la Revista en primer lugar la Sección Científica Nacional, de particular incumbencia a nuestros compañeros que por sus condiciones personales de excelencia han alcanzado posiciones claves para desarrollar su creatividad y disponer de facilidades secuenciales para realizar sus iniciativas e investigaciones; “MEDICINA” esperanzada les abre sus brazos de publicidad acogedora sugiriendo la presentación al final de cada trabajo, así sea preliminar, de un resumen tanto en español como en inglés. Igualmente a los colegas favorecidos por la naturaleza con su predilección por las Humanidades la Revista les requiere y con solícito clamor espera su aporte para la Sección Letras. El imprescindible contingente internacional de actualización científica hace ineludible incluir en “MEDICINA” Compendios o Comentarios Informativos sobre temas de libre elección escritos por Académicos o lectores, lo que de paso les daría un valor docente.

    De las copiosas ediciones actuales la Academia distribuye mil ejemplares e Italmex ocho mil, para un total de nueve mil controlando por computador los nombres de los beneficiarios para evitar duplicación. Nos queda pendiente solucionar la publicación de TEMAS MEDICOS.

    Para la Biblioteca se han estudiado estas iniciativas, entre otras:

    1°. Reglamentación para usuarios, según solicitud de la Bibliotecóloga.

    2°. Reorganización de la Sección de Revistas Médicas estableciendo Canjes formales y adquisiciones permanentes que aseguren la aspiración de llegar a mantener al día y en adecuado “display” las nacionales más importantes y algunas internacionales.

    3°. Campaña para adquirir las faltantes obras médicas de autores colombianos en la Sección Nacional Piloto.

    4°. Tecnificación progresiva y en especial la adopción de un mecanismo práctico que facilite la obtención de Bibliografía actualizada para generar y satisfacer inquietudes de avanzada.

    5°. Idear y promover un fondo financiero sui generis que permita la adquisición renovable oportunamente en cada especialidad del texto más representativo y actualizado a fin de que los académicos y otros usuarios puedan consultar y resolver eventuales emergencias informativas del momento profesional.

    6°. Organización de un kárdex y archivo propios y exclusivos de la Revista “MEDICINA” para almacenar ordenada y permanentemente copias de Actas del Comité, de trabajos llegados para publicación, sean aprobados o no, con su respectiva respuesta a cada autor; correspondencia general, documentos varios, comentarios, decisiones pendientes, proyectos, etc.

    Es de registrar con satisfacción la puntual asistencia a las sesiones mensuales del Comité que se caracterizaron por su aplomo, sensatez y objetividad en sus decisiones y la búsqueda de soluciones al reinante pesimismo sobre las publicaciones por su alto costo actual, lo que afortunadamente contribuyó al encuentro de la solución ya suficientemente mencionada.

    Full Text Available O experimento foi conduzido para avaliar o efeito do estresse de temperatura sobre as características de incubabilidade e qualidade dos pintos nascidos. Trezentos ovos, obtidos de um lote de matrizes de frangos de corte com 42 semanas, foram distribuídos em três incubadoras, reguladas para manter uma temperatura de 37,8ºC, umidade relativa de 60% e viragem mecânica a cada duas horas. Aos 16 dias de incubação (D16, aplicou-se uma variação de temperatura de calor (40ºC ou frio (32ºC durante cinco horas em duas máquinas. Os embriões da terceira máquina foram usados como controle. Os dados obtidos foram analisados estatisticamente, obedecendo-se a um delineamento inteiramente casualizado, com 3 tratamentos. A eclodibilidade e a qualidade dos pintainhos, avaliados pelo peso ao nascer e qualidade de pernas e umbigo não foram significativamente diferentes entre o grupo controle e os grupos estressados. Os resultados revelaram que os ovos exposto ao estresse pelo frio ou calor tiveram um período de incubação maiores - 506,5h e 504,2h, respectivamente - do que aqueles expostos a temperatura normal - 496,3h - como conseqüência no atraso de bicagem interna (7 e 6 h e externa (13 e 14 h. Concluiu-se que a alteração da temperatura normal de incubação, com resfriamento ou aquecimento por 5 h no D16, não foi suficiente para prejudicar a eclodibilidade e a qualidade dos pintainhos, mas causou uma dilatação do período total de incubação, indicando que mesmo um breve período de variação da temperatura normal de incubação em um período crítico de desenvolvimento é suficiente para determinar estresse nos embriões de frangos de corte.This trial was carried out in order to evaluate the effect in broiler embryos of cold or heat stress on the hatching characteristics, and on the quality of the newborn chicks. Three hundred eggs obtained from 42-week-old broiler breeders were distributed in three incubators maintained at a

    Full Text Available Fauna of phlebotomine sand flies (Diptera, Psychodidae in areas with endemic American cutaneous leishmaniasis in the State of Mato Grosso do Sul, Brazil. The aim of this study was to investigate the ecological aspects of the main vectors of American cutaneous leishmaniasis (ACL in four monitoring stations situated in the municipalities of Naviraí, Nova Andradina, Novo Horizonte do Sul and Rio Verde de Mato Grosso. For each monitoring station, the captures of sand flies were undertaken each month from July 2008 to June 2010 using CDC and Shannon traps. The CDC traps were installed simultaneously for three consecutive nights in three collection sites: intradomicile, peridomicile and edge of the forest. A Shannon trap was installed from dusk to 10 pm, inside the forest, one night per month. A total of 7,651 sand flies belonging to nine genera and twenty-nine species were captured. Nyssomyia neivai (52.95%, Psathyromyia hermanlenti (10.91%, Psathyromyia runoides (9.16%, Nyssomyia whitmani (7.95%, Psathyromyia aragaoi (4. 89%, Nyssomyia antunesi (3.14% and Evandromyia bourrouli (2.20% were the most frequent species. Approximately 65% of the sand flies were collected in the forest environment. The municipalities presented significantly different indexes of species diversity. Naviraí presented the lowest species diversity index, however, it showed the highest abundance. Novo Horizonte do Sul had the highest species diversity index, but the lowest abundance (< 5%. It is noteworthy the occurrence of vector species of Leishmania in the areas studied, especially in Naviraí, where Ny. neivai presented high frequencies which may explain the increased number of ACL cases in this municipality.

Foram utilizados 150 pintos machos Cobb distribuídos ao acaso em três tratamentos com cinco repetições de dez aves. Os tratamentos consistiram das formas físicas farelada, triturada e peletizada de uma ração pré-inicial comercial. Com exceção da moela, os órgãos do trato digestório e a estrutura morfométrica do intestino não foram influenciados pela forma física da ração. Maior digestibilidade do N foi obtida com a ração peletizada, enquanto a ração triturada possibilitou maior digestibilidade do EE. A energia metabolizável determinada para a ração farelada foi menor que a obtida nas demais formas físicas da ração. As aves alimentadas com raç��o farelada tiveram menor consumo de ração e ganho de peso e pior conversão alimentar. Ingeriram ainda menos energia, apresentaram menores retenções de proteína, gordura e energia corporal e utilizaram maior proporção da energia ingerida para produção de calor. As rações pré-iniciais na forma peletizada ou triturada possibilitam maior aproveitamento dos nutrientes da ração pelos pintos e melhor desempenho.This experiment was conducted to evaluate the effect of different physical form of pre-starter diet on performance, nutrient utilization and development of gastrointestinal tract of broiler chicks during the first week of age. A total of 150-day-old male broiler chicks was allotted to a completely randomized design with three treatments and five replicates of 10 birds each.

The phlebotomines were captured in the peridomiciliary area, where Shannon traps were utilized in the peridomicile and CDC traps in animal shelters. 2,783 specimens of sandflies were captured, 2,140 females (76.9% and 643 males (23.1%, distributed between 17 species. The most abundant species was Nyssomyia neivai (88.1%, followed by Nyssomyia whitmani (3.1%. The presence of Lutzomyia longipalpis was also confirmed, it is the main vector of Leishmania (L. infantum chagasi which causes visceral leishmaniasis. The presence of species involved in the transmission of leishmaniases in the municipality of Uberlândia is cause for concern. The presence of L. longipalpis indicates that its urbanization may not have been aleatory and instead occurred through the destruction of wild ecotopes.

    The results from an investigation on the possibility that sandflies in an endemic area for American cutaneous leishmaniasis, in the state of Paraná, may have memory are reported. Sandflies were caught in Recanto Marista, Doutor Camargo, State of Paraná, Brazil, using Falcão traps in two chicken sheds (G1 and G2), between November 15 and 26, 2007. A total of 2,080 sandflies were caught (1,000 in G1 and 1,080 in G2) and these were marked and released. Nyssomyia neivai was the most (90.5%) frequent species. Out of the total released, 168 sandflies (8%) were recaptured and the recapture rate in G2 was significant. The results show that it is possible that spatial or olfactory memory and/or host loyalty exists, and that this will guide the sandflies in recognizing the places where sources of blood are available.

    Full Text Available SUMMARY This study reports the fauna and frequency of sandflies in domestic animal shelters, residences and other ecotopes in rural areas of the municipality of Bandeirantes, Paraná State. Sandflies were collected twice in eight rural villages by using Falcon traps from 8pm to 6am in 2008. In these localities 4,790 sandflies were collected, which were represented by ten sandfly species, prevailing of Nyssomyia neivai and Nyssomyia whitmani species. It was observed that animal shelters are the domestic ecotopes where there is the greatest frequency of these insects. The localities where the collections were made had the environmental characteristics that allow the persistence of transmission of parasites from the American tegumentary leishmaniasis. Although the fauna and the behavior of sandflies species are similar in different localities, the method of controlling these insects should be adjusted to the environmental characteristics of each one of the most diverse endemic areas of American tegumentary leishmaniasis in the municipalities of Paraná State.

    According to the Brazilian Government (CONAB, July 2012) the actual area of grain production in the country is close to 50.8 million ha and the perspective of production is 162.6 million of tons. Maize and Soybean are responsible for more than 83% of the total harvest. The area available for agriculture in Brazil is 282.2 million ha or close to 33% of the total land of the country. From 1991 until 2010 the agricultural technology was responsible for an increase of production close to 154% while the planted area raised only 25%. Considering this rate of production in the last 20 years the Ministry of Agriculture made an extrapolation for 2020, when the country can produce close to 176 million of grains being 65 million tons of maize, 86 million tons of soybean and 70 million bags of coffee. In this case, it was not considered any variation in the climate conditions. In 2002, in partnership with the British Embassy in Brazil, Unicamp and Embrapa published the study "Global Warming and the New Geography of Agricultural Production in Brazil" (Pinto and Assad, 2002) based on a Regional Climate Model PRECIS from Hadley Centre, where the grain production was estimated to decrease due to temperature rise. Without considering any mitigation or adaptation action, in the worst scenario (A2-IPCC) the principal crops to be affected will be coffee with 6.7% estimated production decrease until 2020, soybean 22% and corn 12%. On the other hand, sugar cane, as a C4 plant, will have an increase of production in the order of 170%. As suggested by the Word Bank, a new project was developed for a more detailed analysis of the influence of the global warming in the Brazilian agriculture, affecting temperature and water deficit in the years 2020 and 2030. It was considered initially 23 Global Climatic Models (GCM) defined by IPCC, that were separated in blocks of similar comportment using cluster multivariate analysis. Other 3 Regional Climatic Models (RCM) were also used to give more

Os animais foram distribuídos em cinco grupos: 1-controle; e 2 a 5- com 24, 48, 72 e 96 horas pós-inoculação, respectivamente. Fragmentos da bursa de Fabricius foram colhidos para processamento histológico e extração de RNA. Lâminas coradas em HE e TUNEL (marcação in situ da fragmentação do genoma com transferase terminal de deoxinucleotídeo foram utilizadas na morfometria do índice apoptótico. Amostras de mRNA foram testadas para a expressão dos genes VP2 e GAPDH utilizando-se transcrição reversa e RT-PCR. Utilizou-se um kit SYBR GREEN PCR, e a reação foi desenvolvida em ABI Prism 7000 SDS. Os índices apoptóticos cresceram progressivamente indicando uma relação na atrofia bursal causada pelo VDIB. Paralelamente, os resultados da PCR em tempo real demonstraram queda da carga viral nas células linfóides da bursa nos diferentes intervalos de tempo do experimento. Esses resultados sugerem um papel protetor da apoptose na diminuição da replicação viral.Twenty-nine SPF 1-day-old chicks were inoculated with infectious bursal disease virus (IBDV to evaluate early apoptosis and the expression of viral protein 2 (VP2 and glyceraldehyde-3-phosphate dehydrogenease (GAPDH.

    Leishmania (L.) amazonensis (Lainson & Shaw, 1972) and Leishmania (Viannia) braziliensis (Vianna, 1911) are the principal causative agents of American tegumentary leishmaniasis (ATL) in Brazil. L. amazonensis also causes diffuse cutaneous leishmaniasis (DCL) vectored principally by Lutzomyia flaviscutellata and secondarily by Lutzomyia whitmani (Antunes & Coutinho, 1939). The latter is the most common phlebotomine in the state of Maranhão, and it is the focal species for potential ATL transmission. For this reason, we tested the ability of L. whitmani to become infected with Lutzomyia parasites. Phlebotomines were derived from a colony maintained in the laboratorial conditions. The first generation, uninfected females were offered a bloodmeal with mice infected with the strains of both parasites. We found that L. whitmani can become infected with both parasite species, with infection rates of 65.2% (L. braziliensis) and 47.4% (L. amazonensis). We conclude that in Maranhão, L. whitmani is likely an important vector in the transmission of ATL and may function as a vector of DCL. This possibility should be further investigated. © The Authors 2015. Published by Oxford University Press on behalf of Entomological Society of America. All rights reserved.

    Visceral leishmaniasis (VL) is an endemic disease in northeastern Argentina including the Corrientes province, where the presence of the vector and canine cases of VL were recently confirmed in December 2008. The objective of this study was to assess the modelling of micro- and macro-habitat variables to evaluate the urban environmental suitability for the spatial distribution of Lutzomyia longipalpis presence and abundance in an urban scenario. Sampling of 45 sites distributed throughout Corrientes city (Argentina) was carried out using REDILA-BL minilight traps in December 2013. The sampled specimens were identified according to methods described by Galati (2003). The analysis of variables derived from the processing of satellite images (macro-habitat variables) and from the entomological sampling and surveys (micro-habitat variables) was performed using the statistical software R. Three generalised linear models were constructed composed of micro- and macro-habitat variables to explain the spatial distribution of the abundance of Lu. longipalpis and one composed of micro-habitat variables to explain the occurrence of the vector. A total of 609 phlebotominae belonging to five species were collected, of which 56% were Lu. longipalpis. In addition, the presence of Nyssomyia neivai and Migonemya migonei, which are vectors of tegumentary leishmaniasis, were also documented and represented 34.81% and 6.74% of the collections, respectively. The explanatory variable normalised difference vegetation index (NDVI) described the abundance distribution, whereas the presence of farmyard animals was important for explaining both the abundance and the occurrence of the vector. The results contribute to the identification of variables that can be used to establish priority areas for entomological surveillance and provide an efficient transfer tool for the control and prevention of vector-borne diseases.

    Lutzomyia longipalpis, the vector for the causal agent of visceral leishmaniasis (VL), has extended its distribution in the southern cone in the Americas. The first urban record of Lu. longipalpis in Argentina was from the City of Clorinda in 2004. The aim of this study was to analyse the monthly distribution and abundance of Lu. longipalpis and to evaluate its association with environmental and climatic variables in Clorinda City, Province of Formosa. Phlebotominae sampling was performed using CDC light mini-traps that were placed in different sites of the city between January 2012 and December 2013. Environmental variables including the normalised difference vegetation index, normalized difference water index, land surface temperature and precipitation were evaluated using a spatiotemporal model. A total of 4996 phlebotomine sandflies were captured during the study period, and eight species were reported: Lu. longipalpis, Migonemyia migonei, Nyssomyia whitmani, Ny. neivai, Brumptomyia guimaraesi, Evandromyia cortelezzii/sallesi, Psathyromyia bigeniculata and Expapillata firmatoi. This is the first urban record of Ex. firmatoi in Argentina. Lutzomyia longipalpis was the most abundant species between 2012 and 2013, and it appeared in all the sampled sites. Moreover, the model applied showed that ground humidity and temperature were significantly associated with the abundance of Lu. longipalpis. This longitudinal approach at city scale allows for modelling that explains more than 60% of the temporal variability of the abundance of Lu. longipalpis based exclusively on satellite obtained data. The results support the hypothesis of steady 'hot spots' of abundance with time, while other sites could change its abundance due to eventual microenvironment changes. The Lu. longipalpis abundance driving factors are breeding site-related variables, highlighting the importance both for modelling and surveillance to use lag data.

    Full Text Available This study was carried out to investigate the effects of adding baker yeast (BY, chlortetracycline (CTC and both BY + CTC to a control diet containing 200 ng/g of aflatoxin B1 (C + AFB1 on performance, serum parameters and pathologyc alterations of broilers. A total 100 chicks (Ross PM 3 were divided into five groups in individual cages and each containing 20 animals. BY, a rich source of protein and vitamin B complex, was mixed into the diets at 2.0 %, CTC was mixed into the diet at 2.5 ng/g. Feed consumption, body weight and feed efficiency were recorded weekly. Serum parameters and pathologyc alterations were determined at the end of the study. Dead animals were recorded daily. Liver changes were clearly apparent in the C+AFB1and C+ AFB1+CTC most of the livers were enlarged, yellow and had pethecial hemorrhages. Canalicula cholestosis was absent in group C+AFB1 and C+ AFB1+CTC, but not others. When compared to the control (C group, alkaline phosphatase (ALP, appear to be significantly increased in the C+AFB1 and C+CTC+ AFB1 groups. Serum glutamic oxalacetic transaminase (GOTwas increased in C+AFB1 birds. Serum alphaphetoprotein was not affected by the treatments. Feed consumption and body weight were significantly reduced in group AFB1. Birds receiving BY + AFB1, CTC + AFB1 and BY + CTC + AFB1 had a significantly higher body weight than group C+AFB1. Feed efficiency was better in group CTC + AFB1 than the others. The findings of this research suggest tha BY (2% can partly counteract some of the toxic effects of AFB1.Este estudo foi desenvolvido para avaliar os efeitos da adição de Levedura de panificação (BY e cortetraciclina (CTC e ambos BY+CTC a uma dieta controle © contendo 200 ng/g de aflatoxina B1 (C+AFB1 sobre desempenho, parâmetros séricos e alterações patológicas de frangos de corte. Um total de 100 pintinhos (Ross PM3 foi dividido em cinco grupos, em gaiolas individuais, contendo 20 animais para cada grupo. A levedura de panificação, uma fonte rica de proteína e vitamina do complexo B foi adicionada à dieta, à porcentagem de 2% e a CTC, a 2.5 ng/g. Consumo alimentar, peso corporal e eficiência alimentar foram registrados semanalmente. Parâmetros séricos e alterações patológicas foram determinados no final do estudo. Animais mortos foram registrados diariamente. Alterações ocorridas no fígado foram claramente aparentes nas dietas C+AFB1 e C+AFB1+CTC, sendo que a maioria dos fígados apresentou-se aumentado, amarelo e com hemorragia peticial. Canícula colestoses foi ausente nos grupos C+AFB1 e C+AFB1=CTC, mas não nos demais grupos. Quando comparado com o grupo controle©, alcalino fosfatase (ALP, parece que houve aumento significativo nos grupos C+AFB1 e C=CTC=AFB1. Oxaloacético tansaminase glutâmico (GOT sérico foi maior no grupo de aves C+AFB1. Alphafetoproteína sérica não foi afetada pelos tratamentos. Consumo alimentar e peso corporal foram significativamente reduzidos no grupo AFB1. Animais que receberam BY+AFB1, CTC+AFB1 e BY+CTC+AFB1 tiveram aumento significativo no peso corporal, comparado com o grupo C+AFB1. A eficiência alimentar foi melhor no grupo CTC+AFB1 em comparação aos demais. Os resultados desta pesquisa sugerem que BY (2% pode parcialmente neutralizar alguns dos efeitos tóxicos do AFB1.

    Full Text Available Durante o processo de criação de frangos de corte a fase inicial ou fase de aquecimento se caracteriza por ser este o período mais delicado devido à imaturidade fisiológica das aves. Desta forma, os fatores ambientais se destacam por inferir, de forma direta, no crescimento, no desempenho zootécnico e na mantança da vida desses animais. Objetivou-se, com base nessas considerações estudar, com este trabalho, o efeito de três diferentes sistemas de ventilação mínima (por pressão positiva, negativa e natural sobre as variáveis ambientais (temperatura do ar, umidade relativa e velocidade do ar de galpões de frangos de corte, durante a fase de aquecimento. De acordo com os resultados verificou-se que o sistema de aquecimento utilizado não foi satisfatório para manter a temperatura do ar e a umidade relativa dentro de padrões considerados adequados, expondo as aves, assim, a períodos de estresse térmico por frio. Em contrapartida, não ocorreram influências negativas em relação às taxas de ventilação aplicadas para os dois sistemas de ventilação positiva e negativa. A velocidade do ar também se manteve em níveis considerados não estressores para as aves, no período de aquecimento.During the creation process of poultry, the initial or heating phase, is characterized as the most delicate period due to physiological immaturity of the birds. Thus, environmental factors stand out to infer, directly, in the growth, on the performance and maintenance of life of these animals. Based on these considerations, the aim of this study was to study the effect of three different systems of minimum ventilation (positive pressure, negative and natural on environmental variables (air temperature, relative humidity and wind velocity of broiler sheds during the heating phase. According to results obtained, it was verified that the heating system used was inadequate to maintain the air temperature and relative humidity within the standards deemed appropriate, thus exposing the birds to periods of heat stress by cold. In contrast, there were negative influences regarding ventilation rates applied to the two ventilation systems positive and negative. Wind velocity also remained at levels considered non-stressful for young chickens.

    Full Text Available In the Amazon region the phlebotomine fauna is considered one of the most diverse in the world. The use of Shannon traps may provide information on the anthropophily of the species and improve the traps’ performance in terms of diversity and quantity of insects collected when white and black colored traps are used together. This study sought to verify the attractiveness of the traps to the phlebotomine species of the Brazilian Amazon basin using Shannon traps under these conditions. The insects were collected using two Shannon traps installed side by side, one white and the other black, in a primary forest area of the municipality of Xapuri, Acre, Brazil. Samples were collected once a month during the period August 2013 to July 2015. A sample of females was dissected to test for natural infection by flagellates. A total of 6,309 (864 males and 5,445 females specimens (36 species were collected. Psychodopygus carrerai carrerai (42%, Nyssomyia shawi (36%, and Psychodopygus davisi (13%, together represented 90% of the insects collected. Nyssomyia shawi and Psychodopygus davisi were more attracted by the white color. Specimens of Nyssomyia shawi, Nyssomyia whitmani, and Psychodopygus hirsutus hirsutus were found naturally infected by flagellates in the mid and hindgut. This is the first study in Acre state using and comparing both black and white Shannon traps, demonstrating the richness, diversity, and anthropophilic behavior of the phlebotomine species and identifying proven and putative vectors of the etiological agents of leishmaniasis.

    Abstract The detection and identification of natural infections in sand flies by Leishmania protozoan species in endemic areas is a key factor in assessing the risk of leishmaniasis and in designing prevention and control measures for this infectious disease. In this study, we analyzed the Leishmania DNA using nuclear ribosomal internal transcript spacer (ITS) sequences. Parasite DNA was extracted from naturally infected, blood-fed sand flies collected in nine localities considered leishmaniasis-endemic foci in Ecuador. The species of parasites identified in sand flies were Leishmania major-like, Leishmania naiffi, Leishmania mexicana, Leishmania lainsoni, and “Leishmania sp. siamensis”. Sand fly specimens of Brumptomyia leopoldoi, Mycropigomyia cayennensis, Nyssomyia yuilli yuilli, Nyssomyia trapidoi, Pressatia triacantha, Pressatia dysponeta, Psychodopygus carrerai carrerai, Psychodopygus panamensis, and Trichophoromyia ubiquitalis were found positive for Leishmania parasite. These findings contribute to a better understanding of the epidemiology and transmission dynamics of the disease in high-risk areas of Ecuador. PMID:28981860

    Phlebotomine sand flies are dipterans of the family Psychodidae. They are very important to veterinary medicine because some species are vectors of infective forms of Leishmania spp., the etiological agents of leishmaniasis. The Parque Estadual do Rio Doce is located in an area with constant reports of cases of leishmaniasis. In order to better understanding the phlebotamine sand fly fauna of the park, the present work was undertaken with the goal of analyzing phlebotomine sand flies collected there, verifying their seasonality and correlating their presence with forest and/or anthropic areas. To analyze the fauna of phlebotomine sand flies, HP-type, model CDC light traps were distributed along the Juquita trail of PERD. Twelve traps were installed between September 2012 and February 2014, and captured specimens were identified to species. A total of 1993 phlebotomine sand flies of 30 species were captured. The most abundant species were Pressatia choti, Psychodopygus davisi and Nyssomyia intermedia. The high number of Nyssomyia intermedia captured drew attention because they are considered one of the vectors of the infective Leishmania braziliensis present at PERD. No seasonality was observed in the occurrence of phlebotomine sand flies captured at PERD. The number of captured specimens of vector species, and the distance of traps from the forest boarder, were negatively correlated, showing that these vectors (Nyssomyia intermedia, Nyssomyia whitmani and Migonemyia migonei) were less common inside the forest area and that attention should be drawn to other potential vector species in the forest. These results can contribute to leishmaniasis prevention strategies directed at the visitors and professionals at or near PERD. The finding of the presence of Leishmania vectors in the park area must be given attention, since disease transmission can threaten people who visit PERD and its surroundings. Therefore, information on the prevention of leishmaniasis needs to be

    To assess the effect of dietary fiber on glucose tolerance four different meals of varying fiber content but identical protein fat and carbohydrate content were fed to eight healthy men aged 22 to 45. Each meal provided 75 g of carbohydrate as liquid glucose formula, as brown rice, pinto beans, or All Bran. The mean plasma glucose and insulin responses were highest following the formula, and least for All Bran and pinto beans. Rice produced nearly as great a rise in insulin and glucose as did the formula. The rank of each meal by content of neutral detergent fiber was nearly the inverse of the rank by magnitude of the insulin response evoked, fiber content being greatest in All Bran (18 g) and pinto beans (16.2 g), low in rice (2.8 g) and absent from the formula. It was concluded that dietary fiber dampened the insulin response to a high carbohydrate meal.

    Before 1996 the phlebotomine sand fly Lutzomyia neivai was usually treated as a synonym of the morphologically similar Lutzomyia intermedia, which has long been considered a vector of Leishmania braziliensis, the causative agent of much cutaneous leishmaniasis in South America. This report investigates the likely range changes of both sand fly species in response to a stabilisation climate change scenario (RCP4.5) and a high greenhouse gas emissions one (RCP8.5). Ecological niche modelling was used to identify areas of South America with climates currently suitable for each species, and then the future distributions of these climates were predicted based on climate change scenarios. Compared with the previous ecological niche model of L. intermedia (sensu lato) produced using the GARP algorithm in 2003, the current investigation modelled the two species separately, making use of verified presence records and additional records after 2001. Also, the new ensemble approach employed ecological niche modelling algorithms (including Maximum Entropy, Random Forests and Support Vector Machines) that have been widely adopted since 2003 and perform better than GARP, as well as using a more recent climate change model (HadGEM2) considered to have better performance at higher resolution than the earlier one (HadCM2). Lutzomyia intermedia was shown to be the more tropical of the two species, with its climatic niche defined by higher annual mean temperatures and lower temperature seasonality, in contrast to the more subtropical L. neivai. These different latitudinal ranges explain the two species' predicted responses to climate change by 2050, with L. intermedia mostly contracting its range (except perhaps in northeast Brazil) and L. neivai mostly shifting its range southwards in Brazil and Argentina. This contradicts the findings of the 2003 report, which predicted more range expansion. The different findings can be explained by the improved data sets and modelling methods. Our

    Phlebotomine vectors transmit parasites and can cause visceral leishmaniasis (VL) or cutaneous leishmaniasis (TL). Phlebotomine females are hematophagous but need to ingest carbohydrates, possibly promoting the development of protozoan parasites in their digestive tract. The present study evaluated the species composition and abundance across several habitats in a metropolitan landscape, as well as associations among phlebotomines, plants, and local climatic parameters. Three consecutive monthly collections were carried out in an Atlantic Forest fragment, using CDC light traps in peridomestic areas and cashew, coconut, and mango tree. plantations. Eight species of phlebotomine were captured: Evandromyia evandroi, Lutzomyia longipalpis, Psathyromyia shannoni, Sciopemyia sordellii, Evandromyia walkeri, Psychodopygus wellcomei, Nyssomyia whitmani, and Nyssomyia intermedia, primarily from the forest environment. L. longipalpis was confirmed as a species adapted to anthropic environments, while P. wellcomei was shown to be predominately forest-dwelling. Phlebotomines exhibited diversified food consumption patterns in relation to carbohydrate sources. They fed on both native and exotic species of arboreal and shrubby vegetables and gramineous plants. © 2013 The Society for Vector Ecology.

    Phlebotomines are invertebrate hosts of Leishmania genus species which are etiological agents of leishmaniases in humans and other mammals. Sandflies are often collected in entomological studies of caves both in the inner area and the adjacent environments. Caves are ecotypes clearly different from the external environment. Several caves have been opened to public visitation before any studies were performed and the places do not have scientific monitoring of the fauna, flora, geological and geographical characteristics. These events can lead to the loss of geological and biological information. Considering these aspects, this study aimed to describe the sand fly fauna, including the ecological features, in a limestone cave at the Speleological Province of Bambuí (Minas Gerais State, Brazil). A total of 8,354 specimens of sandflies belonging to 29 species were analyzed: Lutzomyia cavernicola (20%), Nyssomyia intermedia (15%), Martinsmyia oliveirai (13%), Evandromyia spelunca (12%), Evandromyia sallesi (11%), Migonemyia migonei (9%), Nyssomyia whitmani (9%), Sciopemyia sordellii (4%) and Lutzomyia longipalpis (2%). The others species represent 5% of the total. This manuscript presents data found on richness, diversity, evenness and seasonality, comparing the sand fly fauna trapped in the cave and its surroundings. PMID:24130847

    Full Text Available Phlebotomine sandflies were captured in rural settlement and periurban areas of the municipality of Guaraí in the state of Tocantins (TO, an endemic area of American cutaneous leishmaniasis (ACL. Forty-three phlebotomine species were identified, nine of which have already been recognised as ACL vectors. Eleven species were recorded for the first time in TO. Nyssomyia whitmani was the most abundant species, followed by Evandromyia bourrouli, Nyssomyia antunesi and Psychodopygus complexus. The Shannon-Wiener diversity index and the evenness index were higher in the rural settlement area than in the periurban area. The evaluation of different ecotopes within the rural area showed the highest frequencies of Ev. bourrouli and Ny. antunesi in chicken coops, whereas Ny. whitmani predominated in this ecotope in the periurban area. In the rural settlement area, Ev. bourrouli was the most frequently captured species in automatic light traps and Ps. complexus was the most prevalent in Shannon trap captures. The rural settlement environment exhibited greater phlebotomine biodiversity than the periurban area. Ps. complexus and Psychodopygus ayrozai naturally infected with Leishmania (Viannia braziliensis were identified. The data identified Ny. whitmani as a potential ACL vector in the periurban area, whereas Ps. complexus was more prevalent in the rural environment associated with settlements.

    The detection and identification of natural infections in sand flies by Leishmania protozoan species in endemic areas is a key factor in assessing the risk of leishmaniasis and in designing prevention and control measures for this infectious disease. In this study, we analyzed the Leishmania DNA using nuclear ribosomal internal transcript spacer (ITS) sequences. Parasite DNA was extracted from naturally infected, blood-fed sand flies collected in nine localities considered leishmaniasis-endemic foci in Ecuador.The species of parasites identified in sand flies were Leishmania major-like, Leishmania naiffi, Leishmania mexicana, Leishmania lainsoni, and "Leishmania sp. siamensis". Sand fly specimens of Brumptomyia leopoldoi, Mycropigomyia cayennensis, Nyssomyia yuilli yuilli, Nyssomyia trapidoi, Pressatia triacantha, Pressatia dysponeta, Psychodopygus carrerai carrerai, Psychodopygus panamensis, and Trichophoromyia ubiquitalis were found positive for Leishmania parasite. These findings contribute to a better understanding of the epidemiology and transmission dynamics of the disease in high-risk areas of Ecuador. © The Authors 2017.

    Cutaneous leishmaniasis is endemic in Salta, the northwestern province of Argentina. We describe an outbreak involving five recreational hunters whose exposure was limited to several hours in a residual patch of primary forest. All patients presented with typical cutaneous lesions after a mean incubation period of 59 days (range 15–78), and one developed simultaneous mucosal involvement. Polymerase chain reaction analysis of lesions confirmed Leishmania (V.) braziliensis as the etiologic agent in three cases. All patients were cured with anti-Leishmania treatment. Entomologic surveys in the transmission area revealed a predominance of Lutzomyia neivai. This outbreak report confirms a microfocal transmission pattern of tegumentary leishmaniasis in the Americas and based on a well-determined exposure, allows the determination of incubation times for leishmaniasis caused by Leishmania braziliensis.

    Full Text Available American Tegumentary Leishmaniasis is endemic in the province of Tucumán since 1916 where the first Argentinian case of leishmaniasis was reported. An epidemic outbreak took place in the province during 1986-1988, after that the number of cases increased gradually again between 1991-1996. Since October of 1999 sand flies captures were performed at different places associated with current and past transmission or sites identified as risky ones. The collections were carried out with CDC mini light trap and modified Shannon trap. In this study 2338 Phlebotominae were captured being prevalent Lutzomyia neivai (Lu intermedia complex (97.7%, followed by Lu. migonei. We report Lu. shannoni for the first time in the province. Phlebotominae was abundant in the warm and humid months and showed a peak before the summer rains. Lutzomyia neivai showed a pattern (peridomestic prevalence, anthropophilia, abundance in secondary forest consistent with other outbreak studies. Thus, the results reinforce this species incrimination as vector of leishmaniasis in the area. Domestic animals close to houses increase its abundance, and so the probable associated risk of human-Phlebotominae contact. Further studies should be done to understand the role of each Phlebotominae species in the transmission of leishmaniasis in Tucumán in order to design entomological surveillance strategies.La Leishmaniasis Tegumentaria Americana es endémica en la provincia de Tucumán desde 1916, lugar donde se reportara el primer caso argentino de leishmaniasis.

    The two-spotted spider mite, Tetranychus urticae Koch, is an important pest of cotton in mid-southern USA and causes yield reduction and deprivation in fiber fitness. Cotton and pinto beans grown in the greenhouse were infested with spider mites at the three-leaf and trifoliate stages, respectively. Spider mite damage on cotton and bean canopies expressed as normalized difference vegetation index indicative of changes in plant health was measured for 27 consecutive days. Plant health decreased incrementally for cotton until day 21 when complete destruction occurred. Thereafter, regrowth reversed decline in plant health. On spider mite treated beans, plant vigor plateaued until day 11 when plant health declined incrementally. Results indicate that pinto beans were better suited as a host plant than cotton for rearing T. urticae in the laboratory.

  3. Late Quaternary slip history of the Mill Creek strand of the San Andreas fault in San Gorgonio Pass, southern California: The role of a subsidiary left-lateral fault in strand switching

    2015-01-01

    The fault history of the Mill Creek strand of the San Andreas fault (SAF) in the San Gorgonio Pass region, along with the reconstructed geomorphology surrounding this fault strand, reveals the important role of the left-lateral Pinto Mountain fault in the regional fault strand switching. The Mill Creek strand has 7.1–8.7 km total slip. Following this displacement, the Pinto Mountain fault offset the Mill Creek strand 1–1.25 km, as SAF slip transferred to the San Bernardino, Banning, and Garnet Hill strands. An alluvial complex within the Mission Creek watershed can be linked to palinspastic reconstruction of drainage segments to constrain slip history of the Mill Creek strand. We investigated surface remnants through detailed geologic mapping, morphometric and stratigraphic analysis, geochronology, and pedogenic analysis. The degree of soil development constrains the duration of surface stability when correlated to other regional, independently dated pedons. This correlation indicates that the oldest surfaces are significantly older than 500 ka. Luminescence dates of 106 ka and 95 ka from (respectively) 5 and 4 m beneath a younger fan surface are consistent with age estimates based on soil-profile development. Offset of the Mill Creek strand by the Pinto Mountain fault suggests a short-term slip rate of ∼10–12.5 mm/yr for the Pinto Mountain fault, and a lower long-term slip rate. Uplift of the Yucaipa Ridge block during the period of Mill Creek strand activity is consistent with thermochronologic modeled uplift estimates.

    1999-02-01

    The effects of UV-B radiation on growth, photosynthesis, UV-B-absorbing compounds and NADP-malic enzyme have been examined in different cultivars of Phaseolous vulgaris L. grown under 1 and 12 mM nitrogen. Low nitrogen nutrition reduces chlorophyll and soluble protein contents in the leaves and thus the photosynthesis rate and dry-matter accumulation. Chlorophyll, soluble protein and Rubisco contents and photosynthesis rate are not significantly altered by ambient levels of UV-B radiation (17 microW m-2, 290-320 nm, 4 h/day for one week). Comparative studies show that under high nitrogen, UV-B radiation slightly enhances leaf expansion and dry-matter accumulation in cultivar Pinto, but inhibits these parameters in Vilmorin. These results suggest that the UV-B effect on growth is mediated through leaf expansion, which is particularly sensitive to UV-B, and that Pinto is more tolerant than Vilmorin. The effect of UV-B radiation on UV-B-absorbing compounds and on NADP-malic enzyme (NADP-ME) activity is also examined. Both UV-B radiation and low-nitrogen nutrition enhance the content of UV-B-absorbing compounds, and among the three cultivars used, Pinto exhibits the highest increases and Arroz the lowest. The same trend is observed for the specific activity and content of NADP-ME. On a leaf-area basis, the amount of UV-B-absorbing compounds is highly correlated with the enzyme activity (r2 = 0.83), suggesting that NADP-ME plays a key role in biosynthesis of these compounds. Furthermore, the higher sensitivity of Vilmorin than Pinto to UV-B radiation appears to be related to the activity of NADP-ME and the capacity of the plants to accumulate UV-B-absorbing compounds.

    The effects of boiling and steaming processes on the antiproliferative and cellular antioxidant properties, as well as phytochemicals, of two types of common beans (pinto and black beans) and two types of soybeans (yellow and black) were investigated. All thermal-processing methods caused significant (pbean types (except for TPC values in pressure-steamed yellow soybeans) as compared to those of the raw beans. All types of uncooked raw beans exhibited cellular antioxidant activities (CAA) in dose-dependent manners. Black soybeans exhibited the greatest CAA, followed by black beans, pinto beans and yellow soybeans. The CAA of cooked beans were generally diminished or eliminated by thermal processing. The hydrophilic extracts from raw pinto beans, black beans and black soybeans exhibited antiproliferation capacities against human gastric (AGS) and colorectal (SW480) cancer cells in dose-dependent manners. The raw yellow soybeans exhibited dose-dependent antiproliferation activities against the SW480 cells. Most of the cooked beans lost their antiproliferation capacities as observed in the raw beans. These results indicate that different processing methods may have various effects on phytochemical profiles and bioactivities. Overall, thermal processing caused a significant reduction of the health-promotion effects of beans. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Condensed tannins are polymers of flavan-3-ols that are produced by many plants in a wide variety of tissues. The ability of these compounds to actively precipitate proteins has been linked to nutritional deficiencies in many animals. Four purified tannins (quebracho, wattle, pinto bean and sorghum) were compared to chemical assays and astringency towards [ 14 C]-BSA. Quebracho and wattle tannins were much less astringent and had longer chain lengths that sorghum or pinto bean tannins. Quebracho tannin had a very high affinity for salivary proline-rich glycoproteins (PRPs) and pinto bean tannin alone had a measurable affinity for soybean trypsin inhibitor. This suggests that tannin/protein interactions in vivo may be very specific. Protein bound carbohydrate enhanced the binding of PRPs to tanning and conferred specificity on the interactions. Carbohydrate also increases the solubility of protein/tanning complexes, which may aid the animal in eliminating the complexes. [ 125 I]-labeled condensed tannin was shown to retain the ability to discriminate between high and low affinity proteins. [ 125 I]-labeled phenols were isolated from livers and kidneys of rats fed [ 125 I]-labeled tannin. The techniques described in this thesis should be widely applicable to studying in vivo functions of condensed tannins

    An entomological survey was conducted from July-December 2009 and September-December 2010, as part of the epidemiological monitoring of American cutaneous leishmaniasis (ACL) in the municipality of Lábrea, state of Amazonas (AM), Brazil. Sandflies were collected using CDC light traps installed in intra and peridomiciliary locations, as well as the border of forested areas around houses where autochthonous cases of ACL were recorded. A total of 510 sandflies belonging to 26 species were collected. The most abundant species was Nyssomyia antunesi (44.5%) followed by Evandromyia walkeri (10.6%) and Micropygomyia rorotaensis (9.8%). Here we also describe Evandromyia (Aldamyia) apurinan sp. nov. and report new records for Trichophoromyia flochi and Evandromyia sipani in AM and Brazil, respectively. Our results describe the composition of the sandfly fauna in the south of AM and suggest Ny. antunesi as the putative vector in the transmission of Leishmania in this area of the Amazon Region.

    Full Text Available INTRODUCTION: Leishmaniasis is expanding across Brazil, including the State of Mato Grosso (MT. The aim of this study was to characterize the phlebotomine sandfly fauna at threerural settlements located in the municipality of Cáceres, MT, from August 2010 to July 2011. METHODS: Sandfly captures were conducted at the forest border and in intra and peridomicile areas with automatic light traps, biweekly, from 5pm to 6am. RESULTS: Of the 630 sandflies collected, 348 were female, and 282 were male. Captured specimens were distributed across 11 genera - Brumptomyia, Evandromyia, Expapillata, Lutzomyia, Martinsmyia, Micropygomyia, Nyssomyia, Pintomyia, Psathyromyia, Psychodopygus, and Sciopemyia - and 28 species. Among these, six species had not been marked yet in MT (Brumptomyia avellari, Br. mangabeirai, Evandromyia aldafalcaoae, Micropygomyia echinatopharynx, Micropygomyia peresi, and Pa. campograndensis. Nyssomyia whitmani was the most abundant species across ecotopes at all settlements. Interestingly, Lutzomyia longipalpis and Lutzomyia cruzi were found in sympatry. CONCLUSIONS: The disorganized occupation of the environment that is happening at the rural settlements of Mata Comprida, Laranjeira I and II could provide opportunities for the domiciliation of wild populations of phlebotomine, including vectors of leishmaniasis. Therefore, more studies are needed to understand the epidemiology of the disease in these areas and its impact on the human population.INTRODUÇÃO: As leishmanioses encontram-se em expansão no Brasil, inclusive no Estado de Mato Grosso (MT.

    Full Text Available In the present study, some morphological structures of antennae, maxillary palps and caudal setae of fourth instar larvae of laboratory-reared phlebotomine sand flies (Lutzomyia longipalpis, L. migonei, L. evandroi, L. lenti, L. sericea, L. whitmani and L. intermedia of the State of Ceará, Brazil, were examined under scanning electron microscopy. The antennal structures exhibited considerable variation in the morphology and position. A prominent digitiform distal segment has been observed only on the antenna of species of the subgenus Nyssomyia. The taxonomic relevance of this and other antennal structure is discussed. The papiliform structures found in the maxillae and the porous structures of the caudal setae of all species examined may have chemosensory function. Further studies with transmission electron microscopy are needed to better understand the physiological function of these external structures.

    A total of 4,840 phlebotomine sand flies from 54 localities in Putumayo department (=state), in the Colombian Amazon region, were collected in Shannon traps, CDC light traps, resting places and from human baits. At least 42 Lutzomyia species were registered for the first time to the department. Psychodopygus and Nyssomyia were the subgenera with the greatest number of taxa, the most common species being L. (N.) yuilli and L. (N.) pajoti. They were sympatric in a wide zone of Putumayo, indicating that they should be treated as full species (new status). Among the anthropophilic sand flies, L. gomezi and L. yuilli were found in intradomiciliar, peridomestic, urban or forest habitats. L. richardwardi, L. claustrei, L. nocticola and L. micropyga are reported for the first time in the Colombian Amazon basin. L. pajoti, L. sipani and L. yucumensis are new records for Colombia.

    Full Text Available Here we present a comprehensive review of the literature on the vectorial importance of the major Anopheles malaria vectors in Colombia. We provide basic information on the geographical distribution, altitudinal range, immature habitats, adult behaviour, feeding preferences and anthropophily, endophily and infectivity rates. We additionally review information on the life cycle, longevity and population fluctuation of Colombian Anopheles species. Emphasis was placed on the primary vectors that have been epidemiologically incriminated in malaria transmission: Anopheles darlingi, Anopheles albimanus and Anopheles nuneztovari. The role of a selection of local, regional or secondary vectors (e.g., Anopheles pseudopunctipennis and Anopheles neivai is also discussed. We highlight the importance of combining biological, morphological and molecular data for the correct taxonomical determination of a given species, particularly for members of the species complexes. We likewise emphasise the importance of studying the bionomics of primary and secondary vectors along with an examination of the local conditions affecting the transmission of malaria. The presence and spread of the major vectors and the emergence of secondary species capable of transmitting human Plasmodia are of great interest. When selecting control measures, the anopheline diversity in the region must be considered. Variation in macroclimate conditions over a species' geographical range must be well understood and targeted to plan effective control measures based on the population dynamics of the local Anopheles species.

    Full Text Available Las Lomitas, Formosa, Argentina, reported 96 cases of tegumentary leishmaniasis during 2002. The urban transmission was suggested although previous outbreaks were related with floods of the Bermejo river (BR 50 km from the village. Phlebotomine collections were performed during March 2002 to define the spatial distribution of risk, together with satellite imaginery. The phlebotomine/trap obtained was 1679.5 in the southern BR shore, 1.1 in the periruban-rural environment and 2.3 in the northern Pilcomayo river marshes. Lutzomyia neivai was the prevalent species (91.1% among the 2393 phlebotomine captured, and it was only found in the BR traps. The other species were L. migonei (7.9%, L. cortelezzii (0.9%, and Brumptomyia guimaraesi (0.1%. The satellite images analysis indicates that the fishing spots at the BR were significantlyoverflowed during the transmission peak, consistent with fishermen recollections. This spatial restricted flood might concentrate vectors, reservoirs, and humans in high places. Therefore, both the spatial distribution of vectors and the sensor remoting data suggests that in Las Lomitas area the higher transmission risk it is still related with the gallery forest of the BR, despite of the urban residence of the cases. The surveillance and control implications of these results are discussed.

    Outbreaks of Clostridium perfringens have been associated with dishes containing refried beans from food service establishments. However, growth of C. perfringens in refried beans has not been investigated, and predictive models have not been validated in this food matrix. We investigated the growth of C. perfringens during the cooling of refried beans. Refried beans (pinto and black, with and without salt added) were inoculated with 3 log CFU/g C. perfringens spores and incubated isothermally at 12, 23, 30, 35, 40, 45, and 50°C. The levels of C. perfringens were monitored 3, 5, 8, and 10 h after inoculation, and then fitted to the Baranyi primary model and the Rosso secondary model prior to solving the Baranyi differential equation. The final model was validated by dynamic cooling experiments carried out in stockpots, thus mimicking the worst possible food service conditions. All refried beans samples supported the growth of C. perfringens, and all models fit the data with pseudo-R(2) values of 0.95 or greater and mean square errors of 0.3 or lower. The estimated maximum specific growth rates were generally higher in pinto beans, with or without salt added (2.64 and 1.95 h(-1), respectively), when compared with black beans, with or without salt added (1.78 and 1.61 h(-1), respectively). After 10 h of incubation, maximum populations of C. perfringens were significantly higher in samples with no salt added (7.9 log CFU/g for both pinto and black beans) than in samples with salt added (7.3 and 7.2 log CFU/g for pinto and black beans, respectively). The dynamic model predicted the growth of C. perfringens during cooling, with an average root mean squared error of 0.44. The use of large stockpots to cool refried beans led to an observed 1.2-log increase (1.5-log increase predicted by model) in levels of C. perfringens during cooling. The use of shallower pans for cooling is recommended, because they cool faster, therefore limiting the growth of C. perfringens.

  11. Catholic populism and education in Brazil

    Science.gov (United States)

    Paiva, Vanilda

    1995-05-01

    Education in Brazil has been profoundly affected by populism, a movement which extols the virtue of the oppressed classes and opposes the traditional teacherstudent relationship. This movement has antecedents in nineteenth-century Russian writers such as Herzen and Bakunin. The author shows how populist ideas, often merging with Marxism, were adopted by many Brazilian Catholics from the 1950s onwards, under the influence of Vieira Pinto, Paulo Freire and others. In the realm of education this often led to an extreme form of anti-authoritarianism. While not denying certain positive aspects of this movement, the author argues that its position is fundamentally self-contradictory.

    To increase legume consumption and give a better protein quality in the snack products, mixtures of fried beans-corn were formulate in different proportions: 60:40 (A); 50:50 (B) and 40:60 (C). Fried corn used in mixtures was previously soaked in a predetermined solution (NaOH/EDTA) and then blanched. Three beans varieties (Pinto 114, Suave 85 and Tórtola Inia) were mixed with fried yellow dent corn in the above described proportions, obtaining nine mixtures whose physical, chemical and sensorial characteristics were evaluated. The mixtures were very homogeneous in all the analyzed characteristics. The protein content for the A mix was the greatest, nevertheless the sensorial analysis showed the last acceptance. The moisture content and water activity of these mixtures was low assuring a good microbiological stability under storage conditions. The protein contribution of each species in different prepared mixtures determined the selection of the best cereal/legume mix. From a nutritional stand point the best results were obtained when the 50% of protein was supplied by bans and the 50% by corn. From the mixtures tried in this study, mix C with bean Pinto 114 one closed to the recommended conditions. Nevertheless, for each cereal/legume mix, the best proportion was C, due to its better acceptability, even though it had less nutritional value.

    Full Text Available Carlo Bertero was trained in Alba and then in Turin, studying with very good teachers who taught him, in addition to botany, political and ethical principles. After having studied the domestic flora, the young botanist travelled to the Antilles (1816-1821, to Chile (1827-1830 and to Tahiti (1830-1831. Thanks to his scientific works many new species were recognized and many specimina were sent to Europe to collectors as well as to botanic gardens, being spread out in different places. When, in 1831, the boat, on which Bertero was boarded, sank into Pacific ocean, all his collection of Tahitian plants disappeared with him. Despite of the dispersion of the collected materials, the botanists have been successful in reconstructing a good part of his activity. Nevertheless his unique writing appeared on the magazine El Mercurio Chileno, when the botanist was living in Santiago during the government of F.A. Pinto, the first liberal president of such country. The historical documentation has disclosed that, during his co-operation with the magazine, the Italian botanist supported the governmental policy, being consistent with his juvenile principles. When Pinto was overthrown, after a fierce civil war, which brought the conservative party to the power, Bertero fell into disgrace and had to leave the country, while the mission to write a natural story of Chile was granted to his competitor, the French botanist Claude Gay, who joined the new political course.

    2010-01-01

    Gene flow is a common phenomenon even in self-pollinated plant species. With the advent of genetically modified plants this subject has become of the utmost importance due to the need for controlling the spread of transgenes. This study was conducted to determine the occurrence and intensity of outcrossing in transgenic common beans. In order to evaluate the outcross rates, four experiments were conducted in Santo Antonio de Goiás (GO, Brazil) and one in Londrina (PR, Brazil), using transgenic cultivars resistant to the herbicide glufosinate ammonium and their conventional counterparts as recipients of the transgene. Experiments with cv. Olathe Pinto and the transgenic line Olathe M1/4 were conducted in a completely randomized design with ten replications for three years in one location, whereas the experiments with cv. Pérola and the transgenic line Pérola M1/4 were conducted at two locations for one year, with the transgenic cultivar surrounded on all sides by the conventional counterpart. The outcross occurred at a negligible rate of 0.00741% in cv. Pérola, while none was observed (0.0%) in cv. Olathe Pinto. The frequency of gene flow was cultivar dependent and most of the observed outcross was within 2.5 m from the edge of the pollen source. Index terms: Phaseolus vulgaris, outcross, glufosinate ammonium.

    Full Text Available INTRODUCTION: An entomological study was conducted as part of a vector-monitoring program in the area associated with the Santo Antônio hydroelectric system in State of Rondônia, Western Amazonian Brazil. METHODS: Fourteen sampling sites were surveyed to obtain data on the potential vectors of Leishmania spp. in the area. Sand flies were collected from 2011 to 2014 during the months of January/February (rainy season, May/June (dry season, and September/October (intermediary season using light traps arranged in three vertical strata (0.5, 1, and 20m. RESULTS : A total of 7,575 individuals belonging to 62 species/subspecies were collected. The five most frequently collected sand flies were Psychodopygus davisi (Root (36.67%, Trichophoromyia ubiquitalis (Mangabeira (8.51%, Nyssomyia umbratilis (Ward & Fraiha (6.14%, Bichromomyia flaviscutellata (Mangabeira (5.74%, and Psychodopygus complexus (Mangabeira (5.25%. These species have been implicated in the transmission of American cutaneous leishmaniasis agents in the Brazilian Amazon region and described as potential vectors of this disease in the study area. CONCLUSIONS: Additional surveillance is needed, especially in areas where these five species of sand fly are found.

    Full Text Available During 2012–2015, an entomological survey was conducted as part of a phlebotomine (Diptera: Psychodidae monitoring program in an area influenced by the Santo Antônio do Jari hydroelectric system (Amapá State, Brazil. The purpose was to study aspects of Amazon/Guianan American cutaneous leishmaniasis (ACL vectors subjected to stresses by anthropogenic environmental changes. For sampling, CDC light traps were positioned 0.5, 1, and 20 m above ground at five capture locations along the Jari River Basin. Fluctuations in phlebotomine numbers were analyzed to determine any correlation with rainfall, dam waterlogging, and/or ACL cases, from May 2012 to March 2015. We captured 2,800 individuals, and among 45 species identified, Bichromomyia flaviscutellata, Nyssomyia umbratilis, and Psychodopygus squamiventris s.l. were determined to be the main putative vectors, based on current knowledge of the Amazon/Guianan ACL scenario. Rainfall, but not complete flooding, was relatively correlated with phlebotomine fluctuation, mainly observed for Ps. squamiventris s.l., as were ACL cases with Ny. umbratilis. Behavioral changes were observed in the unexpected high frequency of Bi. flaviscutellata among CDC captures and the noncanopy dominance of Ny. umbratilis, possibly attributable to environmental stress in the sampled ecotopes. Continuous entomological surveillance is necessary to monitor the outcomes of these findings.

    From 1996 to 1999 multi-trapping methods (Center of Diseases Control, CDC) light traps, light-baited Shannon traps, and aspiration on tree bases) were used to study the phlebotomine fauna of the "Serra do Navio" region of the Brazilian State of Amapá, which is part of the Guiana Shield. Fifty-three species were identified among 8,685 captured individuals. The following species, associated with the transmission of American cutaneous leishmaniasis in Amazonian Brazil, were captured: Nyssomyia umbratilis (3,388), Psychodopygus squamiventris maripaensis (995), Ny. anduzei (550), Trichophoromyia ubiquitalis (400), Ny. whitmani (291), Ps. paraensis (116), and Bichromomyia flaviscutellata (50). Flagellate infections were detected in 45 flies. Of the 19 parasites isolated in vitro, 15 were Leishmania (Viannia) guyanensis (13 in Ny. umbratilis, 1 in Ny. whitmani, 1 in Ny. anduzei) and three were L. (V.) naiffi (2 in Ps. s. maripaensis, 1 in Ny. anduzei). The results indicate the participation of three phlebotomine species in the transmission of L. (V.) guyanensis and two species in that of L. (V.) naiffi, and show that the same phlebotomine species is involved in the transmission of different Leishmania (Viannia) species in the Guianan/Amazon region. A review of the literature together with the results of the present study, and other published and unpublished results, indicate that eight phlebotomine species potentially participate in the transmission of Leishmania (Viannia) naiffi in Amazonia. © A.A.A. de Souza et al., published by EDP Sciences, 2017.

    PCR-based identification of vertebrate host bloodmeals has been performed on several vectors species with success. In the present study, we used a previously published PCR protocol followed by DNA sequencing based on primers designed from multiple alignments of the mitochondrial cytochrome b gene used to identify avian and mammalian hosts of various hematophagous vectors. The amplification of a fragment encoding a 359 bp sequence of the Cyt b gene yielded recognized amplification products in 192 female sand flies (53%), from a total of 362 females analyzed. In the study area of Casa Branca, Brazil, blood-engorged female sand flies such as Lutzomyia longipalpis (Lutz & Neiva, 1912), Migonemyia migonei (França, 1924), and Nyssomyia whitmani (Antunes & Coutinho, 1939) were analyzed for bloodmeal sources. The PCR-based method identified human, dog, chicken, and domestic rat blood sources. © The Authors 2017. Published by Oxford University Press on behalf of Entomological Society of America.

    In Amazonian Brazil the etiological agents of American cutaneous leishmaniasis (ACL) belong to at least seven Leishmania species but little is known about the putative phlebotomine sand fly vectors in different biomes. In 2002–2003 a survey of the phlebotomine fauna was undertaken in the “Floresta Nacional do Tapajós”, Belterra municipality, in the lower Amazon region, western Pará State, Brazil, where we recently confirmed the presence of a putative hybrid parasite, L. (V.) guyanensis × L. (V.) shawi shawi. Sand flies were collected from Centers for Disease Control (CDC) light traps, Shannon traps and by aspiration on tree bases. Females were dissected and attempts to isolate any flagellate infections were made by inoculating homogenized midguts into Difco B45 medium. Isolates were characterized by monoclonal antibodies and isoenzyme electrophoresis. A total of 9,704 sand flies, belonging to 68 species or subspecies, were collected. Infections were found in the following sand flies: L. (V.) naiffi with Psychodopygus hirsutus hirsutus (1) and Ps. davisi (2); and L. (V.) shawi shawi with Nyssomyia whitmani (3) and Lutzomyia gomezi (1). These results provide strong evidence of new putative transmission cycles for L. (V.) naiffi and L. (V.) s. shawi.

    Cutaneous leishmaniasis is a neglected tropical disease transmitted by phlebotomine sand flies of the genus Lutzomyia. In South America, cutaneous leishmaniasis is endemic in the majority of countries. There are no previous reports of phlebotomine sand fly host feeding sources in Ecuador. We identified blood meal sources for phlebotomine sand fly species in Valle Hermoso, a hyper endemic area for leishmaniasis in Ecuador. Phlebotomine sand fly collections were carried out during the dry and rainy seasons. PCR and multiplex PCR were performed from DNA extracted from the abdomens of blood-fed females to specifically identify the avian and mammalian blood meal sources. Avian-blood (77%), mammalian-blood (16%) and mixed avian-mammalian blood (7%) were found in the samples. At the species level, blood from chickens (35.5%), humans (2.8%), cows (2.8%) and dogs (1.9%) was specifically detected. Nyssomyia trapidoi was the most common species of Lutzomyia found that fed on birds. The present results may aid the development of effective strategies to control leishmaniasis in Ecuador.

    Full Text Available Cutaneous leishmaniasis (CL in the state of Rio de Janeiro is sporadic and can be characterised as a peridomestic transmission that occurs in modified natural environments. The aim of this work was to study the fauna and ecological characteristics of sandflies in an environmentally protected area (the State Park of Serra da Tiririca within the remnants of the Atlantic Forest in the municipalities of Niterói and Maricá and their possible relationship with leishmaniasis. Captures were performed using light traps during the night once a month for one year in both sylvatic environments and areas surrounding homes near the park. A total of 1,037 sandflies were captured, belonging to nine genera and 12 species: Evandromyia tupynambai (34.1%, Migonemyia migonei (20.6%, Brumptomyia cunhai (13.8%, Micropygomyia schreiberi (9.7%, Psathyromyia lanei (6.5%, Brumptomyia nitzulescui (5.7%, Evandromyia edwardsi (5.4%, Nyssomyia intermedia (2.8%, Evandromyia cortelezzii (0.6%, Pintomyia bianchigalatiae (0.5%, Lutzomyia longipalpis (0.2% and Sciopemyia microps (0.1%. Both Mg. migonei and Ny. intermedia may be acting as vectors of CL in this area.

    To contribute to the knowledge of the role of small mammals in the transmission cycle of tegumentary leishmaniasis caused by Leishmania braziliensis, we studied the small mammal community and its temporal and spatial association with phlebotominae, as well as small mammal infection by Leishmania spp. by PCR-RFLP analyses in an endemic area of northeastern Argentina. Ten small mammal samplings were conducted (2007-2009, 7506 Sherman trap nights and 422 cage trap nights). In two of these samplings, 16 capture stations each one consisting of a CDC light trap to capture phlebotominae, two to four Sherman traps and two cage traps were placed. We found co-occurrence of phlebotominae and small mammal captures in four stations, which were all the stations with small mammal captures and yielded 97% (2295 specimens, including 21 gravid females) of the total phlebotominae captures, suggesting that small mammals may provide a potential source of blood for phlebotominae females. One Didelphis albiventris and two Rattus rattus were associated with high captures of Nyssomyia whitmani, vector of L. braziliensis in the study area. The PCR-RFLP analyses confirm the presence of L. braziliensis in two sigmodontine small mammals (Akodon sp. and Euryoryzomys russatus) for the first time in Argentina, to our knowledge.

    Sand flies were captured weekly with CDC light traps from December 2003 to November 2005 in three areas of Campo Grande, in the Brazilian state of Mato Grosso do Sul. These areas incorporated two patches of remnant forest and five houses. The blood meals of engorged female sand flies were identified using the avidin-biotin system of immunoenzymatic ELISA capture. Most (327/355) of the females analysed were Lutzomyia longipalpis, of which 66.4% reacted with human blood, 64.8% with that of birds and 8.9% with that of dogs. Females that had taken human blood predominated in the residential areas and two forest patches. The following combinations of blood were also detected for L. longipalpis in some of the samples analysed: bird+human (43.4%), bird+human+dog (6.1%). The combination bird+human+dog+pig was also found for Nyssomyia whitmani. Dogs and pigs appear to have little attractiveness for L. longipalpis. The results obtained demonstrate the eclecticism and high anthropophily of L. longipalpis and raise new questions with regard to the importance of dogs in VL epidemiology and the possible role of man as a source of infection for sand flies.

    Full Text Available SUMMARY The first Argentinian autochthonous human case of visceral leishmaniasis (VL was confirmed in Posadas (Misiones in 2006. Since then, the disease has increased its incidence and geographical distribution. In the 2006-2012 period, 107 human cases were detected (11 deaths. The presence of Lutzomyia longipalpis was detected in peridomiciles in Puerto Iguazú urban area in 2010; some of these findings were associated with households where cases of canine VL had already been reported. The objective of this study was to ascertain the abundance and spatial distribution of Lu. longipalpis in Puerto Iguazú City, on the Argentina-Brazil-Paraguay border. Lu. longipalpis proved to be exclusively urban and was found in 31% of the households sampled (n = 53, 67% of which belonged to areas of low abundance, 20% to areas of moderate abundance and 13% to areas of high abundance. Nyssomyia whitmani was the only species found both in urban and peri-urban environments, and Migonemyia migonei was registered only on the outskirts of the city. Due to the fact that Puerto Iguazú is considered to be at moderate risk at the moment, it is necessary to intensify human and canine case controls, as well as take integrated prevention and control measures regarding the environment, vectors and reservoirs on the Argentina-Brazil-Paraguay border area.

    The aims of this study were to carry out a serological survey of canine leishmaniasis and identify the phlebotomine fauna in the urban area of Bonito, Mato Grosso do Sul. The serological survey was conducted on a sample of 303 dogs, by means of the indirect immunofluorescence test. Phlebotomines were captured using automated light traps. The serological survey found that 30% of the dogs were seropositive, both from the center and from all districts of the town. A total of 2,772 specimens of phlebotomines were caught and the species most found was Lutzomyia longipalpis (90.4%), which corroborated its role as the vector of for canine visceral leishmaniasis in the region. Phlebotomines of the species Bichromomyia flaviscutellata (the main vector for Leishmania (Leishmania) amazonensis) and Nyssomyia whitmani (the vector for Leishmania (Viannia) brasiliensis) were also caught. The findings indicate the need for continuous epidemiological surveillance, with attention towards diminishing the vector breeding sites and the transmission of these diseases in that region.

    This study updates the geographic distributions of phlebotomine species in Central-West Brazil and analyses the climatic factors associated with their occurrence. The data were obtained from the entomology services of the state departments of health in Central-West Brazil, scientific collections and a literature review of articles from 1962-2014. Ecological niche models were produced for sandfly species with more than 20 occurrences using the Maxent algorithm and eight climate variables. In all, 2,803 phlebotomine records for 127 species were analysed. Nyssomyia whitmani, Evandromyia lenti and Lutzomyia longipalpis were the species with the greatest number of records and were present in all the biomes in Central-West Brazil. The models, which were produced for 34 species, indicated that the Cerrado areas in the central and western regions of Central-West Brazil were climatically more suitable to sandflies. The variables with the greatest influence on the models were the temperature in the coldest months and the temperature seasonality. The results show that phlebotomine species in Central-West Brazil have different geographical distribution patterns and that climate conditions in essentially the entire region favour the occurrence of at least one Leishmania vector species, highlighting the need to maintain or intensify vector control and surveillance strategies.

    The expansion of transmission of cutaneous leishmaniasis from sylvatic ecosystems into peri-urban and domestic settings has occurred as sand flies have adapted to anthropogenic environmental modifications. Assessment of the intradomiciliary presence of sand flies in households of the settlement "La Cabaña", in the Department of Risaralda, Colombia, revealed an abundance of Warileya rotundipennis. This unexpected observation motivated further analyses to evaluate the participation of this species in the transmission of cutaneous leishmaniasis. Collections using CDC light traps were conducted during two consecutive nights in May and August 2011.The total of 667 sand flies collected were classified into five species: W. rotundipennis (n=654; 98.05%), Nyssomyia trapidoi (n=7; 1.04%); Lutzomyia (Helcocyrtomyia) hartmanni (n=3; 0.44%); Lutzomyia lichyi (n=2; 0.29%) and Psychodopygus panamensis (n=1; 0.14%). The striking predominance of W. rotundipennis within households during both wet (May) and dry (August) seasons, anthropophilic behavior demonstrated by human blood in 95.23% (60/63) evaluable blood-engorged specimens, and natural infection (5/168-3%) with genetically similar parasites of the Leishmania (Viannia) subgenus observed in a patient in this community, support the involvement of W. rotundipennis in the domestic transmission of cutaneous leishmaniasis in "La Cabaña".

    Full Text Available In recent years, the number of cases of urban malaria in Buenaventura, Colombia, has increased, rising from 576 in 1987 to 3296 in 1991 and 2017 in 1992. For this reason, an epidemiologic study to identify malaria transmission patterns was carried out in this municipality on Colombia’s Pacific coast. This article describes the entomologic findings regarding the vectors, their breeding sites, and the behavior of Anopheles species during the period from June 1993 to May 1994. Of the 469 potential breeding sites identified in the urban area, 28 were positive for anophelines, while in neighboring zones 20 out of 80 potential breeding sites were positive for the immature forms of these mosquitoes. Mining excavations, lakes, and commercial fish and crayfish rearing ponds were the places where A. albimanus was most frequently found. For A. nuñeztovari, the breeding sites were rain puddles and aquiculture ponds. A. neivai larvae were collected from bromeliads. Mosquitoes were collected both inside and outside houses, and 90% of the collected mosquitoes were identified as A. albimanus. Of the female A. albimanus, 54.8% were parous. This species was found to have peak peridomiciliary activity between 6 p.m. and 10 p.m. The highest biting rate outside houses was 7.1 bites per person-hour and was observed during March. It is hoped that this entomologic information will permit the launching of a strong community participation process and the implementation of control measures that are guided by these results.En los últimos años, el número de casos de malaria urbana en Buenaventura, Colombia, ha aumentado de 576 en 1987 a 3296 en 1991 y 2017 en 1992, por lo que se desarrolló un estudio epidemiológico para identificar patrones de transmisión de la malaria en este municipio del litoral pacífico colombiano.

    Anopheles calderoni was first recognized in Colombia in 2010 as this species had been misidentified as Anopheles punctimacula due to morphological similarities. An. calderoni is considered a malaria vector in Peru and has been found naturally infected with Plasmodium falciparum in Colombia. However, its biting behaviour, population dynamics and epidemiological importance have not been well described for Colombia. To assess the contribution of An. calderoni to malaria transmission and its human biting behaviour and spatial/temporal distribution in the southwest of Colombia, human landing catches (HLC) and larval collections were carried out in a cross-sectional, entomological study in 22 localities between 2011 and 2012, and a longitudinal study was performed in the Boca de Prieta locality in Olaya Herrera municipality between July 2012 and June 2013. All mosquitoes determined as An. calderoni were tested by ELISA to establish infection with Plasmodium spp. Larvae of An. calderoni were found in four localities in 12 out of 244 breeding sites inspected. An. calderoni adults were collected in 14 out of 22 localities during the cross-sectional study and represented 41.3% (459 of 1,111) of the collected adult specimens. Other species found were Anopheles albimanus (54.7%), Anopheles apicimacula (2.1%), Anopheles neivai (1.7%), and Anopheles argyritarsis (0.2%). In the localities that reported the highest malaria Annual Parasite Index (>10/1,000 inhabitants) during the year of sampling, An. calderoni was the predominant species (>90% of the specimens collected). In the longitudinal study, 1,528 An. calderoni were collected by HLC with highest biting rates in February, May and June 2013, periods of high precipitation. In general, the species showed a preference to bite outdoors (p Colombia. Its observed preference for outdoor biting is a major challenge for malaria control.

    Glanidium melanopterum Miranda Ribeiro, a typical representative of the subfamily Centromochlinae (Siluriformes: Auchenipteridae), is herein described myologically and compared to other representative species within the group, Glanidium ribeiroi, G. leopardum, Tatia neivai, T. intermedia, T. creutzbergi, Centromochlus heckelii, and C. existimatus. The structure of seven pairs of striated cephalic muscles was compared anatomically: adductor mandibulae, levator arcus palatini, dilatator operculi, adductor arcus palatini, extensor tentaculi, retractor tentaculi, and levator operculi. We observed broad adductor mandibulae muscles in both Glanidium and Tatia, catfishes with depressed heads and smaller eyes. Similarities between muscles were observed: the presence of a large aponeurotic insertion for the levator arcus palatini muscle; an adductor arcus palatini muscle whose origin spread over the orbitosphenoid, pterosphenoid, and parasphenoid; and the extensor tentaculi muscle broadly attached to the autopalatine. There is no retractor tentaculi muscle in either the Glanidium or Tatia species. On the other hand, in Centromochlus, with forms having large eyes and the tallest head, the adductor mandibulae muscles are slim; there is a thin aponeurotic or muscular insertion for the levator arcus palatini muscle; the adductor arcus palatini muscle originates from a single osseous process, forming a keel on the parasphenoid; the extensor tentaculi muscle is loosely attached to the autopalatine, permitting exclusive rotating and sliding movements between this bone and the maxillary. The retractor tentaculi muscle is connected to the maxilla through a single tendon, so that both extensor and retractor tentaculi muscles contribute to a wide array of movements of the maxillary barbels. A discussion on the differences in autopalatine-maxillary movements among the analyzed groups is given. (c) 2005 Wiley-Liss, Inc.

    The transmission of Leishmania involves several species of sand flies that are closely associated with various parasites and reservoirs, with differing transmission cycles in Brazil. A study on the phlebotomine species composition has been conducted in the municipality of Divinópolis, Minas Gerais, Brazil, an endemic area for cutaneous leishmaniasis (CL), which has intense occurrence of visceral leishmaniasis (VL) cases. In order to study the sand flies populations and their seasonality, CDC light traps (HP model) were distributed in 15 houses which presented at least one case of CL or VL and in five urban parks (green areas). Collections were carried out three nights monthly from September 2010 to August 2011. A total of 1064 phlebotomine specimens were collected belonging to two genera and seventeen species: Brumptomyia brumpti, Lutzomyia bacula, Lutzomyia cortelezzii, Lutzomyia lenti, Lutzomyia sallesi, Lutzomyia longipalpis, Lutzomyia migonei, Lutzomyia intermedia, Lutzomyia neivai, Lutzomyia whitmani, Lutzomyia christenseni, Lutzomyia monticola, Lutzomyia pessoai, Lutzomyia aragaoi, Lutzomyia brasiliensis, Lutzomyia lutziana, and Lutzomyia sordellii. L. longipalpis, the main vector of Leishmania infantum in Brazil, was the most frequent species, accounting for 76.9% of the total, followed by L. lenti with 8.3%, this species is not a proven vector. Green and urban areas had different sand flies species composition, whereas the high abundance of L. longipalpis in urban areas and the presence of various vector species in both green and urban areas were also observed. Our data point out to the requirement of control measures against phlebotomine sand flies in the municipality of Divinópolis and adoption of strategies aiming entomological surveillance.

    The effects of calcium (Ca 2+ ) level in the soak water, blanch water and brine, blanching temperature, and total seed solids on dry bean canning quality were investigated to optimise a laboratory canning protocol. A linear increase in the Ca 2+ level of soak water, blanch water and brine resulted in a linear decrease in hydration coefficient and percent washed drained weight but a linear increase in texture. Low Ca 2+ level (10 mg kg -1 ) reduced the hydration time for dry bean seed from 14 to 1 h. Blanching temperatures of 50, 70 and 88 °C had non-significant effects on canning quality traits. Blanching for 30 min at 70 °C for black bean or at 88 °C for navy bean and pinto bean resulted in percent washed drained weight ≥ 60, as required by the Canada Agricultural Products Standards Act. Seed solids levels of 95-97 g per 300 × 407 (14 fl oz) can were sufficient to attain a percent washed drained weight of 60. It was confirmed that the thermal processing conditions (115.6 °C retort temperature, 45 min) used in this study were sufficient to achieve commercial sterility. The optimised lab protocol for evaluation of the canning quality of dry bean breeding lines is as follows. Seed containing 95 g of solids for pinto bean, 96 g for navy bean and 97 g for black bean is soaked in water for 30 min at 20 °C and blanched for 30 min at 70 °C for black bean and 88 °C for navy bean and pinto bean in water containing 10 mg kg -1 of Ca 2+ . The seed is then transferred to a 300 × 407 can, filled with brine containing 10 mg kg -1 of Ca 2+ , 1.3% (w/v) of NaCl and 1.6% (w/v) of sugar. The can is then sealed, processed in steam at 115.6 °C for 45 min and cooled at 20 °C for 20 min. Cans are stored for at least 2 weeks prior to quality evaluation of the canned product. Canning of dry bean seed according to this protocol results in precise estimation of canning quality traits, particularly percent

    Full Text Available Abstract Background Many consumers avoid eating beans because they believe legume consumption will cause excessive intestinal gas or flatulence. An increasing body of research and the 2010 Dietary Guidelines for Americans supports the benefits of a plant-based diet, and legumes specifically, in the reduction of chronic disease risks. The purpose of the current research was to investigate the perception of increased flatulence and gastrointestinal discomfort among participants who consumed a ½ cup of beans daily for 8 or 12 weeks. Methods Participants in three studies to test the effects of beans on heart disease biomarkers completed the same weekly questionnaire to assess gastrointestinal discomfort issues such as increased flatulence, stool changes, and bloating. Studies 1 and 2 were randomized crossover trials. Participants consumed ½ cup of pinto beans, black-eyed peas, and canned carrots as control (n = 17 in Study 1 for three randomized 8-week phases. For Study 2, participants ate ½ cup baked beans or canned carrots as control (n = 29 for two randomized 8-week phases. Study 3 was a parallel arm trial with 40 subjects receiving ½ cup pinto beans and 40 consuming a control soup for 12 weeks. Changes in the frequency of perceived flatulence, stool characteristics, and bloating were the primary outcome measures. Chi-square distributions were examined for the presence or absence of symptoms and demographic characteristics to determine differences by gender, age, body mass index (BMI, and bean type. Results Less than 50% reported increased flatulence from eating pinto or baked beans during the first week of each trial, but only 19% had a flatulence increase with black-eyed peas. A small percentage (3-11% reported increased flatulence across the three studies even on control diets without flatulence-producing components. Conclusions People's concerns about excessive flatulence from eating beans may be exaggerated. Public health nutritionists

    Treatment of the cleft palate has evolved over a long period of time. Various techniques of cleft palate repair that are practiced today are the results of principles learned through many years of modifications. The challenge in the art of modern palatoplasty is no longer successful closure of the cleft palate but an optimal speech outcome without compromising maxillofacial growth. Throughout these periods of evolution in the treatment of cleft palate, the effectiveness of various treatment protocols has been challenged by controversies concerning speech and maxillofacial growth. In this article we have evaluated the results of Pinto's modification of Wardill-Kilner palatoplasty without radical dissection of the levator veli palitini muscle on speech and post-op fistula in two different age groups in 20 patients. Preoperative and 6-month postoperative speech assessment values indicated that two-layer palatoplasty (modified Wardill-Kilner V-Y pushback technique) without an intravelar veloplasty technique was good for speech.

    The middle leaflet from the first trifoliate leaf of pinto bean plants (Phaseolus vulgaris) was subjected to various ozone levels for both 12 and 24 h to show moderate oxidant injury. Rates of leaf expansion were used as criteria to measure the effects of ozone at three leaflet positions. Growth analysis included Y-intercepts indicating growth after day 1, growth after day 3, and regression line slopes between days 1 and 7 after the beginning of the experiments. Slopes of growth rate regression lines differentiated untreated leaflets from leaflets exposed to a 0.60 ppm-h (0.05 ppm for 12 h) dose. Growth rates of plants exposed to 1.20 ppm-h (either 0.05 ppm for 24 h, or 0.10 ppm for 12 h) were distinguishable from untreated plants within three days. Basal leaf portions showed the most differential ozone response compared with lateral and tip positions.

    The zircon and monazite U-Pb minimum age of the Hercynian peraluminous two-mica composite granite pluton of Cabeceiras de Basto (Northern Portugal) is 311 {+-} 1 Ma (2 {sigma}). This age, well constrained by a concordant monazite of 311{+-}4 Ma (2{sigma}), is in good agreement with the age suggested for the syn-kinematic, syn-D3, Iberian granites of the Hercynian orogeny (315-305; Pinto et al., 1987). The ({sup 87}Sr/{sup 86}Sr){sub i} and {xi}{sub Nd} isotopic ratios, calculated for 311 Ma, suggest that the three granite units which constitute the massif may derive from an heterogeneous crustal source dated (upper intercept of the discordance) around 1200 Ma.

    2004-03-01

    Activity waves in disinhibited neocortical slices have been used as a biological model for epileptic seizure propagation [1]. Such waves have been mathematically modeled with integro-differential equations [2] representing non-local reaction diffusion dynamics of an excitable medium with an excitability threshold. Stability and propagation speed of traveling pulse solutions depend strongly on the threshold in the following manner: propagation speed should decrease with increased threshold over a finite range, beyond which the waves become unstable. Because populations of neurons can be polarized with an applied electric field that effectively shifts their threshold for action potential initiation [3], we predicted, and have experimentally verified, that electric fields could be used globally or locally to speed up, slow down and even block wave propagation.

Since centuries, in Central Asia, it is the basic staple for the Koumiss production (Savini, 1946; Storch, 1985. Because of its peculiar chemical and nutritional characteristics (Malacarne et al., 2002, recently mare’s milk is utilised also in human nutrition and for cosmetics (Drogoul et al., 1992. This arouses new interest for the study of mare’s milk, in particular concerning the effect of genetic, physiological and feeding factors on organic and inorganic milk components (Doreau and Boulot, 1989; Mariani et al., 1993; Doreau, 1994.

    1992-02-01

    A 1991 study by Pinto and Priest demonstrated the effectiveness of advertisements employing moderate levels of guilt in inducing guilt responses in subjects. Because individuals' responses to guilt are often influenced by their specific personality characteristics, researchers have pointed to the potential moderating effects of individual difference variables such as level of self-esteem and locus of control on individuals' susceptibility to guilt appeals. A study was conducted to evaluate the possibility that self-esteem and locus of control can act as covariates across three treatment levels of guilt advertising. From a sample of 57 working mothers, advertisements stimulating medium and high levels of guilt elicited significantly greater feelings of guilt in subjects than the control advertisement stimulating low guilt. However, the relationship between susceptibility to guilt appeals and self-esteem and locus of control was not observed to covary.

Thus it can be seen as indirect taxes on foods affect the monetary income and consumption pattern of households. To reach the objectives proposed, will be used the Pintos-Payeras (2008 model. The database iscomposed by microdata from the Household Budgeting Survey (POF 2008-2009 and the tax regulations of the country and the southern states of Brazil. The results show that indirect taxes on food in Southern Brazil is regressive when based on income and expenditure of household , ie , the poorest people pay proportionately more taxes and have their consumption pattern highest taxed ICMS (Brazilian value added tax is the tax that contributes most to the regressivity.

    Projects abound in society, and turned from an ‘accidental profession’ to an attractive career path (Pinto & Kharbanda, 1995). In this line, engineers and engineering students are increasingly recognizing the criticality of project management to their own profession. The consequence is that we need...... to educate an increasing number of students in project management. At the Technical University of Denmark (DTU) - one of the leading engineering universities in Scandinavia - the number of students taking our courses has increased organically from 150 to over 300 in the last 5 years - a number...... to change education of project engineers at DTU with the vision to educate large number of students and enable them to reflect and experience how to DO projects, as oppose to teaching normative tools and techniques.

  14. Permanent metabolic stimulation in leaves induced by small gamma irradiation doses and its bioenergetical bases

    Pozsar, B.

    1979-01-01

    According to Schober (1896) the physiological functions of plants can be stimulated by small-dose acute gamma irradiation. The activity of the alcohol dehydrogenase was tested by the production of the acetaldehyde mg, related to 200 mg fresh leaf weight of bean (Pinto variety) and peas (BR-13 and DCP-94 varieties) plants. The stimulating effect of different reducing compounds (glutathione, ascorbic acid, cysteine) in additive treatment was also investigated in the respect of the alcohol dehydrogenase activity. The reducing compounds remarkably increase the activity of the alcohol dehydrogenase. The experimental results indicate that the primary water ionization is followed by secondary long-lasting proton transport through the reducing compounds to the dehydrogenase system. (author)

    Full Text Available The problems of scheduling and optimization of operational conditions in multistage, multiproduct continuous plants with intermediate storage are simultaneously addressed. An MINLP model, called TSPFLOW, which is based on the TSP formulation for product sequencing, is proposed to schedule the operation of such plants. TSPFLOW yields a one-order-of-magnitude CPU time reduction as well as the solution of instances larger than those formerly reported (Pinto and Grossmann, 1994. Secondly, processing rates and yields are introduced as additional optimization variables in order to state the simultaneous problem of scheduling with operational optimization. Results show that trade-offs are very complex and that the development of a straightforward (rule of thumb method to optimally schedule the operation is less effective than the proposed approach.

    Coccidioides immitis and C. posadasii are the etiologic agents of coccidioidomycosis, an endemic fungal disease of the Americas. In Colombia, this mycosis is uncommon, and only five cases, two of them imported, have been documented.By means of DNA sequencing, C. immitis was identified in formalin-fixed, paraffin-embedded archival tissues samples from the 5th Colombian patient diagnosed in 1997. The patient was born in Pinto, Department of Magdalena, and had never visited other geographic regions, a reason to consider that the mycosis had been acquired locally.This species is primarily found in California although it has been occasionally reported in other geographic areas such as Mexico and Brazil. This is the first indigenous report of C. immitis-associated coccidioidomycosis in a Colombian patient. © The Author 2015.

Symptom type of the disease is very similar to that of peanut (A. hypogea witches’ broom, which has been well known to be associated with phytoplasma. Both A. pintoi and A. hypogea witches’ broom causal agent are transmissible to both healthy A. pintoi or A. hypogea, with grafting or vector transmission using peanut witches’ broom phytoplasma specific vector, Orosius argentatus. All combination of transmission means resulted in an identical type of witches’ broom symptom. Further confirmation using polymerase chain reaction detection and identification of phytoplasma employing universal primer pair for phytoplasmas (P1/P7, showed that all of the diseased plants, either from field or transmitted plants is associated with phytoplasma. The A. pintoi witches’ broom phytoplasma is likely identical to that of A. hypogea.Key words: Arachis pintoi, Orosius argentatus, phytoplasma, witches’ broom

    The candidate crops for planetary food systems include: wheat, white and sweet potatoes, soybean, peanut, strawberry, dry bean including le ntil and pinto, radish, rice, lettuce, carrot, green onion, tomato, p eppers, spinach, and cabbage. Crops such as wheat, potatoes, soybean, peanut, dry bean, and rice can only be utilized after processing, while others are classified as ready-to-eat. To process foods in space, the food processing subsystem must be capable of producing a variety of nutritious, acceptable, and safe edible ingredients and food produ cts from pre-packaged and resupply foods as well as salad crops grown on the transit vehicle or other crops grown on planetary surfaces. D esigning, building, developing, and maintaining such a subsystem is b ound to many constraints and restrictions.

    Vincent, Paul

    Differential SAR interferometry is applied to the study of low-rate interseismic crustal deformation fields along three regions of the San Adreas fault system: Salton Sea (southernmost region), Pinto Mountain fault (south-central region), and San Francisco Bay (northern region). New techniques are developed to analyze and model these low-rate deformation fields including constrained horizontal-vertical component deconvolution, deformation phase pattern analysis and strain field evolution modeling. Several new active faults were discovered as well as unmeasured activity on existing faults in the process of this SAR interferometry study. The feasibility and limitations of InSAR as a tool to study low-rate deformation fields is also addressed.

    We report the case of a 75-year-old woman who developed an acute bilateral angle-closure associated with choroidal effusion a day after an uneventful cataract surgery. The same patient had undergone a similarly uneventful cataract surgery two weeks before, under the same protocol, with no postoperative complication in the other eye. Medical treatment, including the use of oral sulfamide-related drugs (acetazolamide), topical beta-blockers and steroids led to a gradual decrease in intraocular pressure (IOP) and choroidal effusion. Despite initial reports suggesting a link between sulfamide-exposure and these rare forms of angle-closure, our report would suggest a more complex pathophysiology behind this intriguing phenomenon.

    Full Text Available Avaliou-se a suplementação enzimática em rações contendo milheto ou sorgo sobre a microbiota intestinal e o desempenho de frangos. Foram alojados 420 pintos - ensaio de microbiota - e 1.200 pintos - ensaio de desempenho -, submetidos aos tratamentos com sorgo ou milheto suplementados ou não com complexo enzimático. O delineamento utilizado foi inteiramente ao acaso, com sete repetições de 15 aves cada, para o ensaio de microbiota, e em blocos ao acaso, com cinco repetições e 60 aves por parcela para desempenho. Foram realizadas pesquisas de bactérias Gram-negativas e contagem do número total de microrganismos aeróbios do intestino delgado. A suplementação enzimática não afetou a microbiota intestinal de frangos aos 14 e 28 dias de idade. Houve efeito da suplementação enzimática nas dietas com sorgo para conversão alimentar na fase pré-inicial. Nas dietas com milheto, a suplementação melhorou o ganho de peso no período de um a 35 dias de idade. No período total de criação, de um a 42 dias, não foi observado efeito da suplementação para milheto ou sorgo. Conclui-se que a utilização da suplementação de enzimas em rações com sorgo ou milheto pode melhorar os resultados de desempenho, dependendo da fase de crescimento de frangos de corte.

    Full Text Available RESUMO O objetivo deste estudo foi avaliar o efeito do fornecimento de dietas pós-eclosão suplementadas com diferentes fontes de gordura insaturada e adicionadas ou não de taurina e glicina sobre o desempenho produtivo, a biometria e a morfometria do intestino delgado de pintos de corte de um a 21 dias de idade. Foram utilizados 480 pintos de corte machos de um dia de idade da linhagem Cobb. O delineamento foi inteiramente ao acaso, em esquema fatorial 2 x 4, com e sem suplementação de taurina e glicina e quatro dietas (controle, óleo de peixe, de soja e de girassol, totalizando oito tratamentos com seis repetições de 10 aves cada. As rações experimentais foram fornecidas de zero a quatro dias de idade. O desempenho zootécnico foi avaliado ao alojamento e aos quatro, sete e 21 dias de idade. Nestas mesmas datas, foram sacrificadas duas aves por unidade experimental para biometria do intestino e histomorfometria da mucosa do intestino. A adição de diferentes fontes de gordura e a suplementação de glicina e taurina às dietas de transição não influenciaram o desempenho produtivo de um a 21 dias. A suplementação das dietas com glicina e taurina alterou a morfologia da mucosa intestinal, principalmente do duodeno, resultando em maior comprimento do vilo e relação vilo:cripta. Entretanto, parte dos efeitos positivos depende do tipo de óleo adicionado, mostrando que dietas pós-eclosão acrescidas de fontes de lipídios podem ser benéficas no desenvolvimento da capacidade funcional do intestino de frangos de corte.

Argumento que, tendo produzido textos que conferiam um papel fundamental à raça como princípio explicador dos fenômenos sociais num momento em que as abordagens racistas perdiam terreno na antropologia em favor de interpretações de tipo culturalista, Vianna desenvolveu, de forma reativa, uma argumentação cujo cerne era a defesa da cientificidade do conceito de raça como chave interpretativa da vida social. Concluo com uma leitura exploratória do diálogo que o autor estabeleceu com dois de seus contemporâneos, Arthur Ramos e Roquette-Pinto, em torno da abordagem científica exigida pelos estudos raciais e das funções político-administrativas que Vianna atribuía à ciência.The present article analyzes Oliveira Vianna's text Race and assimilation, in which the author tried to build a scientific discourse on racial differences and their impact on the assimilation of immigrants. This discourse produced several texts that attributed a fundamental role to race as the cause for social phenomena at a time when anthropological racist views were falling behind due to cultural-oriented approaches. Vianna's reactive arguments were based on the defense of a scientific concept of race as the key to the interpretation of society. At the end of the article, the author analyzes the correspondence Vianna kept with Arthur Ramos and Roquette-Pinto on the scientific approaches demanded by racial studies, as well as on the political and administrative functions he attributed to science.

    As large-scale stellar surveys have become available over the past decade, the ability to detect and characterize substructures in the Galaxy has increased dramatically. These surveys have revealed the Triangulum-Andromeda (TriAnd) region to be rich with substructures in the distance range 20-30 kpc, and the relation of these features to each other, if any, remains unclear. An exploration using Two Micron All Sky Survey (2MASS) photometry reveals not only the faint sequence in M giants detected by Rocha-Pinto et al. spanning the range 100° < l < 160° and –50° < b < –15°, but, in addition, a second, brighter and more densely populated sequence. These sequences are likely associated with the distinct main sequences (MSs) discovered (and labeled TriAnd1 and TriAnd2) by Martin et al. in an optical survey in the direction of M31, where TriAnd2 is the optical counterpart of the fainter red giant branch (RGB)/asymptotic giant branch sequence of Rocha-Pinto et al. Here, the age, distance, and metallicity ranges for TriAnd1 and TriAnd2 are estimated by simultaneously fitting isochrones to the 2MASS RGB tracks and the optical MS/MS turn-off features. The two populations are clearly distinct in age and distance: the brighter sequence (TriAnd1) is younger (6-10 Gyr) and closer (distance of ∼15-21 kpc), whereas the fainter sequence (TriAnd2) is older (10-12 Gyr) and at an estimated distance of ∼24-32 kpc. A comparison with simulations demonstrates that the differences and similarities between TriAnd1 and TriAnd2 can simultaneously be explained if they represent debris originating from the disruption of the same dwarf galaxy, but torn off during two distinct pericentric passages.

Ambos fueron inmigrantes del último periodo borbónico y sus vidas se cruzaron en el Potosí bajo colonial al incorporarse en la misma red de paisanaje, a partir de donde ingresarán a la misma familia por matrimonio. En este contexto, las redes y los vínculos trazados previamente fueron los que permitieron la subsistencia y reproducción de las empresas ya existentes. Se analizan vínculos mercantiles, de paisanaje, familiares y diferentes estrategias comerciales que involucraban al espacio andino y que revelan las distintas opciones que los flujos mercantiles ofrecían al sector empresarial.This paper studies the lifetime of two businessmen from Jujuy during the period between the Colony and the early Independence: Manuel de Tezanos Pinto andjosep de Alvarado. They both became immigrants in the last Borbon period and met in the late colonial Potosi when joining the same native-net; eventually, they share by marriage. In this context, it was the nets and bonds -traced previously- the ones that allowed the subsistence and reproduction of the companies already in existence. Mercantile, native-net and family bonds are analyzed along with the different commercial strategies which used to involve the Andean space and that reveal the different options that the mercantile flows offered to the business sector.

    Full Text Available O desenvolvimento embrionário nas aves tem início antes mesmo da postura. A variabilidade do estágio de desenvolvimento embrionário no momento da oviposição é conhecida e influencia a taxa de eclosão, uma vez que estágios muito avançados ou muito precoces são prejudiciais por tornarem os embriões mais sensíveis ao estresse do armazenamento. O aquecimento de ovos férteis no período entre a postura e o armazenamento vem sendo estudado como forma de reduzir os efeitos negativos do armazenamento sobre o rendimento de incubação por permitir que os embriões progridam até um estágio em que são mais aptos a suportar o estresse do armazenamento. Este experimento teve como objetivo avaliar os efeitos do aquecimento artificial de ovos de matrizes pesadas no período entre a coleta e o armazenamento sobre o rendimento de incubação e o peso do pinto ao nascimento. Foram utilizados 5.760 ovos de matrizes pesadas Cobb(r com 57 semanas de idade. O delineamento experimental foi inteiramente ao acaso, constituído por quatro tratamentos definidos com base no tempo de aquecimento dos ovos (zero, três, seis e nove horas. O aquecimento foi feito em câmara de fumigação a 30°C, e os ovos foram armazenados por três dias. O aquecimento artificial no período entre a coleta e o armazenamento não influenciou a eclodibilidade, a mortalidade embrionária e o peso do pinto ao nascimento, tendo sido, nessas circunstâncias, uma prática injustificada.

    Although leishmaniases are regarded as serious public health issues in the State of Tocantins, as consequence of the impact of environmental changes, small advances in taxonomic and ecological studies of Phlebotominae fauna are taking place in this state. The present study aimed to improve the knowledge about the sand flies, as well as about the aspects of the bioecology of leishmaniases vectors from Porto Nacional, a city that was directly impacted by the construction of Luís Eduardo Magalhães Hydroelectric Plant (HEP-Lajeado). Sand flies were collected monthly using CDC light traps and Shannon traps for a period of 40 consecutive months, at different monitoring stations, where 7162 specimens were collected and 48 species were detected. Among the species found, 22 are first records in the state and seven are considered important vectors of leishmaniases. Lutzomyia longipalpis, the vector of American Visceral Leishmaniasis (AVL) showed higher frequency in urban compared to rural areas, and Nyssomyia whitmani, the vector of American Cutaneous Leishmaniasis (ACL), predominated in rural areas. The frequency and habits of sand fly vectors are discussed considering environmental characteristics and climatic factors. The construction of dams requires a great amount of labor, therefore attracting people from elsewhere. Increased migration, without adequate structure, leads to bad living conditions in new and unplanned settlements. It also leads to deforestation associated with environmental impacts, which can facilitate the spread of leishmaniases. This study discusses the importance of Lu. longipalpis and Ny. whitmani on the transmission cycles of leishmaniases in Porto Nacional and the record of Bi. flaviscutellata in periurban area of the city.

OBJECTIVE To analyse the occurrence of Phlebotominae in gallery forests and household units (HUs in the city of Palmas and to determine the rate of natural infection by trypanosomatids. METHODS Gallery forests and adjacent household areas were sampled on July (dry season and November (rainy season in 2014. The total sampling effort was 960 HP light traps and eight Shannon traps. Trypanosomatids were detected in Phlebotominae females through the amplification of the SSU rDNA region, and the positive samples were used in ITS1-PCR. Trypanosomatid species were identified using sequencing. FINDINGS A total of 1,527 sand flies representing 30 species were captured in which 949 (28 spp. and 578 (22 spp. were registered in July and November, respectively. In July, more specimens were captured in the gallery forests than in the HUs, and Nyssomyia whitmani was particularly frequent. In November, most of the specimens were found in the HUs, and again, Ny. whitmani was the predominant species. Lutzomyia longipalpis was commonly found in domestic areas, while Bichromomyia flaviscutellata was most frequent in gallery forests.

    Lutzomyia (Nyssomyia) anduzei has been recognized as a secondary vector of Leishmania guyanensis in the Brazilian Amazon region. Since L. anduzei is anthropophilic, co-exists in areas of high leishmaniasis transmission and has been found infected with L. guyanensis, the understanding of the vector population structure and of the process responsible for it is paramount to the vector management and control efforts. In this study we analyzed 74 and 67 sequences of the COI and Cytb loci, respectively, from mitochondrial DNA, aiming to estimate the intra-population genetic variability and population structure in six L. anduzei samples from the Brazilian Amazon region. For COI, we found 58 haplotypes, low to high (FST=0.0310-0.4128) and significant (P=0.0033) genetic structure, and reduced gene flow among populations. The haplotype network yielded many reticulations that likely resulted from hypervariability in the locus. For Cytb, we observed 27 haplotypes, low to moderate (FST=0.0077-0.1954) and nonsignificant (P>0.05) genetic structure for the majority of comparisons and extensive gene flow among populations, in line with the haplotypes network data. AMOVA analysis indicated that most of the variation occurred within populations (83.41%, 90.94%); nevertheless, there were significant differences (ΦST=0.0906-0.1659; P=0.00098; P=0.00000) among them for both loci. The Mantel test showed that the genetic structure is not associated to an isolation-by-distance (IBD) model in either of both loci. These data suggest that L. anduzei is genetically very diverse. The genetic structure lacking IBD may be due to adaptation to local habitats and the low dispersal capacity of the sandflies, and both could lead to population fragmentation and geographic isolation. These findings have important implications for epidemiology, surveillance and vector control and may be a first step in understanding the evolutionary history of this species.

    Leishmania is transmitted by Phlebotominae insects that maintain the enzootic cycle by circulating between sylvatic and domestic mammals; humans enter the cycles as accidental hosts due to the vector's search for blood source. In Colombia, leishmaniasis is an endemic disease and 95% of all cases are cutaneous (CL), these cases have been reported in several regions of the country where the intervention of sylvatic areas by the introduction of agriculture seem to have an impact on the rearrangement of new transmission cycles. Our study aimed to update vector species distribution in the country and to analyze the relationship between vectors' distribution, climate, land use and CL prevalence. A database with geographic information was assembled, and ecological niche modeling was performed to explore the potential distribution of each of the 21 species of medical importance in Colombia, using thirteen bioclimatic variables, three topographic and three principal components derived from NDVI. Binary models for each species were obtained and related to both land use coverage, and a CL prevalence map with available epidemiological data. Finally, maps of species potential distribution were summed to define potential species richness in the country. In total, 673 single records were obtained with Lutzomyia gomezi, Lutzomyia longipalpis, Psychodopygus panamensis, Psathyromyia shannoni and Pintomyia evansi the species with the highest number of records. Eighteen species had significant models, considering the area under the curve and the jackknife results: L. gomezi and P. panamensis had the widest potential distribution. All sand fly species except for Nyssomyia antunesi are mainly distributed in regions with rates of prevalence between 0.33 to 101.35 cases per 100,000 inhabitants and 76% of collection data points fall into transformed ecosystems. Distribution ranges of sand flies with medical importance in Colombia correspond predominantly to disturbed areas, where the

    Full Text Available The auchenipterid catfish genus Tatia is revised. Twelve species are recognized including three described as new. Tatia is diagnosed by the hyomandibula elongated anterodorsally, the anal-fin base of adult males reduced in length, and the caudal peduncle laterally compressed and deep with a middorsal keel. Tatia aulopygia occurs in the Madeira river drainage and is distinguished by the reduced cranial fontanel in adults and male modified anal fin with middle rays reduced in length. Tatia boemia, known from the upper Uruguay river drainage, is distinguished by its unique color pattern with dark chromatophores on the sides of body. Tatia brunnea from river basins in Suriname and French Guiana and the Negro river drainage, Amazon basin, is recognized by its wide head and mouth and by the male modified anal fin with sharply pointed tip. Tatia dunni, from the upper Amazon basin, is recognized by its narrow head, long postcleithral process in some specimens, and body coloration with irregular blotches or stripes. Tatia galaxias, endemic to the Orinoco river basin, is distinguished by its large eye and short snout. Tatia gyrina, distributed in the upper and central Amazon basin and in northern Suriname, has a uniquely reduced mesethmoid, slightly protruding lower jaw, second nuchal plate with slightly concave lateral borders, third nuchal plate reduced, small prevomer, low number of ribs, low number of vertebrae and sexual dimorphism regarding intumescent male genital papilla. Tatia intermedia, recorded from central and lower Amazon basin, Tocantins river, and coastal drainages in Guyana, Suriname, French Guiana, and eastern Pará State, Brazil, is distinguished by the short postcleithral process, small eye and long snout.

    Full Text Available Abstract – The human communicative activity was always determined, over the centuries, by the use of conversational strategies that the interactants put in place in order to exchange information through illocutionary acts, characterized by various discursive and narrative sequences employed to get communicative purposes during the verbal interaction. Through the analysis of four dialogues extracted from two literary Portuguese language works of two different centuries, we demonstrate how the conversational structures of verbal exchanges have not changed over the time, despite the different schools and literary currents that have occurred since the medieval times until the contemporary era. The text chosen are taken from the novels A queda d'um anjo and Amor de perdição: memorias duma família of Camilo Castelo Branco (1825-1890 and from the contemporary work Não há coincidências of Margarida Rebelo Pinto: the choice of these extracts was not random, but taking into account the use of dialogue as a conversational technique, between characters, by these authors who use it in their fiction works in order to involve more actively the reader on the reported events. Keywords: conversation analysis, illocutionary acts, narrative sequences, Camilo Castelo Branco, Margarida Rebelo Pinto. Resumen - A actividade comunicativa humana sempre foi determinada, ao longo dos séculos, pelo uso de estratégias conversacionais que os interactantes põem em prática para trocar informações através de actos ilocutórios, caracterizados por várias sequências discursivas e narrativas empregadas conforme os fins comunicativos que os interactantes querem atingir durante a interacção verbal.

    Full Text Available Tropical grasslands under lowland soils are generally underutilized and the litter of forage legumes may be used to recover these degraded pastures. The objective of this work was to study the dynamics of litter decomposition of Arachis pintoi (pinto peanut, Hyparrhenia rufa (thatching grass and a mixture of both species in a lowland soil. These treatments were analyzed in three areas: grass monoculture, legume monoculture and legume intercropped with the grass during the dry and wet seasons. Litter bags containing the legume, grass or a mixture of both species were incubated to estimate the decomposition rate and microorganism colonization. Decomposition constants (K and litter half-lives (T1/2 were estimated by an exponential model whereas number of microorganisms in specific media were determined by plate dilution. The decomposition rate, release of nutrients and microorganisms number, especially bacteria, increased when pinto peanut was added to thatching grass, influenced by favorable lignin/N and C/N ratios in legume litter. When pinto peanut litter was incubated in the grass plots, 50% N and P was released within about 135 days in the dry season and in the wet season, the equivalent release occurred within 20 days. These results indicate that A. pintoi has a great potential for nutrient recycling via litter and can be used to recover degraded areas.Pastagens tropicais sobre solos de várzea são geralmente subutilizadas.

    Full Text Available Foram conduzidos três experimentos para avaliar a influência da inoculação in ovo de ácido linoléico, glicose e glutamina em ovos de matrizes pesadas aos 16 dias de incubação sobre a eclodibilidade e o desempenho dos pintos até 10 dias de idade. O delineamento utilizado foi em blocos ao acaso, com cinco tratamentos, que consistiram da inoculação dos ovos, conforme descrito a seguir: experimento 1 - 0, 100, 200 ou 300 µL de ácido linoléico; experimento 2 - 0, 100, 200 ou 300 mg de glicose; experimento 3 - 0, 10, 20 ou 30 mg de glutamina. Em todos os experimentos, o grupo controle foi representado por ovos íntegros não inoculados. Na fase pré-eclosão, cada um dos 130 ovos representou uma unidade experimental e, na fase pós-eclosão, cada tratamento contou com quatro repetições de 15 aves. A inoculação de ácido linoléico ou glicose aumentou a mortalidade embrionária, diminuiu a eclodibilidade dos ovos e prejudicou a relação peso do pinto:peso do ovo. Pintos mais leves foram obtidos com a inoculação in ovo de diferentes níveis de ácido linoléico. A inoculação in ovo com ácido linoléico, glicose e glutamina nas concentrações testadas não se mostrou adequada para melhorar características relacionadas à eclodibilidade e ao desempenho de aves até os 10 dias de idade.Three experiments were carried out to evaluate the effects of in ovo inoculation of linoleic acid, glucose, and glutamine in chick eggs at 16th day of incubation on hatchability and performance until 10 days of age. It was used a randomized block design with five treatments, as follows: in experiment 1, 0, 100, 200 or 300 µL of linoleic acid; in experiment 2, 0, 100, 200 or 300 mg of glucose; and in experiment 3, 0, 10, 20 or 30 mg of glutamine. The control was represented by the intact eggs in all experiments. In the pre hatch phase, each one of 130 eggs represented an experimental unit, and in post hatch phase each treatment had four replicates

O delineamento utilizado foi o inteiramente casualizado, com cinco tratamentos, nove repetições e dez aves por unidade experimental. As características estudadas foram desempenho e composição de carcaça, em que a estimativa da exigência de energia metabolizável das aves foi feita por meio de regressão linear ou quadrática, conforme o melhor ajuste. O ganho de peso, o consumo de energia metabolizável e as deposições de proteína e gordura na carcaça aumentaram, enquanto a conversão alimentar dos pintos reduziu de forma linear com os tratamentos. O rendimento de carcaça das aves não foi influenciado pelos níveis de EM da ração. Os níveis de EM da ração modificaram a composição da carcaça e aumentaram o peso de gordura abdominal. Os pintos de corte de 1 a 21 dias de idade, mantidos sob alta temperatura, exigem, no mínimo, relação energia:proteína de 13,6 para melhor desempenho e deposição de proteína na carcaça.Four hundred and fifty Avian Farms male broilers chicks with 48±0.3g of live weight were used in an experiment carried out at climatic chambers to evaluate the effect of the metabolizable energy levels (2850; 2925; 3000; 3075 and 3150 kcal of ME/kg, from 1 to 21 days, maintained at high environmental temperature (34ºC and 60% RH. A completely randomized design, with five treatments (ME levels, nine replicates and ten birds per experimental unit, was used. Performance and carcass composition were evaluated and the metabolizable energy requirement of the birds were obtained by linear or quadratic regression, according to the best fit. Weight gain

    2014-05-01

    The correct representation of extreme windstorms in regional models is of great importance for impact studies of climate change. The Iberian Peninsula has recently witnessed major damage from winter extratropical intense cyclones like Klaus (January 2009), Xynthia (February 2010) and Gong (January 2013) which formed over the mid-Atlantic, experienced explosive intensification while travelling eastwards at lower latitudes than usual [Liberato et al. 2011; 2013]. In this paper the explosive development of these storms is simulated by the advanced mesoscale Weather Research and Forecasting Model (WRF v 3.4.1), initialized with NCEP Final Analysis (FNL) data as initial and lateral boundary conditions (boundary conditions updated in every 3 hours intervals). The simulation experiments are conducted with two domains, a coarser (25km) and nested (8.333km), covering the entire North Atlantic and Iberian Peninsula region. The characteristics of these storms (e.g. wind speed, precipitation) are studied from WRF model and compared with multiple observations. In this context simulations with different Planetary Boundary Layer (PBL) schemes are performed. This approach aims at understanding which mechanisms favor the explosive intensification of these storms at a lower than usual latitudes, thus improving the knowledge of atmospheric dynamics (including small-scale processes) on controlling the life cycle of midlatitude extreme storms and contributing to the improvement in predictability and in our ability to forecast storms' impacts over Iberian Peninsula.

    Objective: Plants absorb radioactive elements from phosphate fertilizers, and also from naturally occurring radiation in the soil, air and water. It has long been known that low doses of ionizing radiation evoke stimulatory effects in a wide variety of living organisms. However, as far as we know, there is no published report on the bio-positive effects of diagnostic doses of X-rays on plant growth. The aim of this study was to evaluate the bio-effects of low doses of diagnostic X-rays on growth rate of Phaseolus vulgaris (Pinto) plants. Materials and Methods: Before cultivation, Phaseolus vulgaris (Pinto) seeds were soaked in tap water for 2 days followed by another 2 days of covering under a wet cloth. Four hundred newly cultivated seeds were randomly divided into two groups of 200 plants each. In this experiment, two seeds were cultivated in each dish (100 dishes for irradiation group and 100 for sham-irradiation group). Fifteen days after starting cultivation, newly grown plants were irradiated with X-rays. Plants were exposed to a single dose of X-ray (80 kVp, 80 mAs) for 6 days. On day 29, plants were pulled out from the ' soil. Length of plant stem, length of root, number of leaves and plant weight were measured. Results: The stem length in irradiated and sham-irradiated plants was 296.5{+-}13.57 and 223.96{+-}15.02 mm respectively. This difference was statistically significant (P<0.001). Although the number of leaves in irradiated plants was higher than that of sham-irradiated plants (7.05{+-}0.18 and 6.74{+-}0.19 respectively), the difference was not statistically significant. The stem diameter in irradiated and sham-irradiated plants were 3.52{+-}0.12 and 3.35{+-}0.09 mm respectively, but the difference again was not statistically significant (P<0.00 1). Plant weight in irradiated samples was less than that of non-irradiated plants but it was not statistically significant. Conclusions: The overall results indicate that diagnostic doses of X-rays can

    Full Text Available Nesse experimento, avaliou-se o efeito de diferentes lâminas de irrigação e coberturas do solo sobre aspectos qualitativos e de produção do mamão cv. "Golden" no período de dezembro de 2003 a novembro de 2004. Utilizou-se delineamento em blocos casualizados, com três repetições, em esquema fatorial. Os resultados encontrados demonstram uma alta correlação entre a época de colheita com a incidência da mancha fisiológica e as variáveis de produção. Com relação à mancha fisiológica do mamão (MFM, confirmou-se o aspecto sazonal de incidência, sendo que a cv. "Golden" apresentou a maior incidência do distúrbio no mês de setembro. Com relação às coberturas de solo, a cobertura morta se mostrou promissora para os fatores em estudo, ao contrário da cobertura verde com a leguminosa Arachis pintoe, pois a mesma, provavelmente, competiu por água e nutrientes com o mamoeiro, acarretando, assim, redução na sua produtividade.In this experiment the effect of different irrigation rates and soil coverings on qualitative aspects as well as yield components of the papaya cv. ‘Golden’ during the period December 2003 to November 2004 were evaluated. A randomized complete block design was used with three replications in a factorial scheme. The results demonstrate high correlation involving the factors harvest season, incidence of skin freckles and yield components. With relation to skin freckles a seasonal incidence was confirmed, showing that for cv. ‘Golden’, the major incidence of the disturbance was verified in September. The mulching treatment was promising for the factors studied, in contrast to the green covering using the leguminosae Arachis pintoe, due to competition with the papaya trees for water and nutrients, causing a reduction in the yield components.

Those studies in Brazil began in 1908 with the pioneer works conducted by Roquette-Pinto and Oscar Freire, who noted the high diversity of the native fauna of necrophagous insects and the impossibility of direct application of the methods developed in Europe. In the last two decades, forensic entomology advanced rapidly in Brazil, but there still are some important limitations, especially in relation to the taxonomy, biology and ecology of necrophagous insects and the lack of interaction between researchers and police investigators. Today there are in Brazil over 20 researchers involved with forensic entomology and tens of police investigators with some training in this field. Guidelines for the development of this field of investigation in Brazil are also presented.

    The Precambrian basement of Uruguay consists of three major terranes separated and crosscut by wide NE-striking subvertical transcurrent shear zones. The western terrane as a part of the Rio de la Plata Craton is known as the Piedra Alta Terrane (PAT). This is separated from the Nico Perez Terrane by the Sarandi del Yi-Piri olis subvertical shear zone (Bossi et al., 1993). A mafic dykes complex intruded the PAT at 1.8 Ga and was not later deformed. The PAT has equivalent rocks in the igneous-metamorphic basement of Tandilia region and the Martin Garcia Island, Buenos Aires Province, Argentina (Dalla Salda et al., 1988; Cingolani and Dalla Salda, 2000). The PAT shows no evidence of the Neoproterozoic orogenies and is considered a best preserved Paleoproterozoic block (Transamazonian Cycle). It contains three E-W trending belts of volcano-sedimentary rocks with low grade metamorphism. These are from south to north: Pando, San Jose and Andresito belts (Bossi et al., 1996). Associated with them, three granitic-gneissic zones he Ecilda Paullier, Florida and Feliciano- were recognized with magmatic intrusives emplaced at different crustal levels. The San Jose belt is the largest supracrustal unit and contains abundant volcanic and volcaniclastic rocks of low grade metamorphic (Paso Severino Fm.) with sheets of granitic rocks intercalated (Mutti et al., 1996; Bossi et al., 1996). The associated granitic rocks are of large areal extension, mostly granodiorites and tonalites, and minor monzogranite and gabbro (e.g. Cerro Rospide region), including xenoliths from Paso Severino Fm. Towards the north of the San Jose belt an important Florida granitized zone is developed in the central part of the PAT, where the Pintos massif was recognized. The main purpose of this contribution is to offer new Rb-Sr geochronological data from two granitoid units, The Cerro Rospide intrusive in Paso Severino Fm. and Pintos massif included in medium grade migmatic-metamorphic complex and its

Explantation of dislocated IOL and iris claw IOL (ICIOL are the techniques that have been used in our ophthalmic department. The aim of this study is to report our technique for retropupillar ICIOL.Methods: This study is a retrospective case series. A total of 105 eyes with dislocated IOL from the patients at the Department of Ophthalmology in Santa Maria Hospital, a tertiary reference hospital in Lisbon, Portugal, from January 2012 until January 2016, had been analyzed. Of these 105 eyes, 66 eyes had dislocated one-piece IOL and 39 eyes had dislocated three-piece IOL. The latter underwent iris suture of the same IOL and were excluded from this study. The remaining 66 eyes with dislocated one-piece IOL underwent pars plana vitrectomy, that is, explantation of dislocated IOL through corneal incision and an implantation of retropupillary ICIOL. Operative data and postoperative outcomes included best corrected visual acuity, IOL position, intraocular pressure, pigment dispersion, clinical signs of endothelial cell loss, and anterior chamber depth.Results: The mean follow-up was 23 months (range: 6–48 months. The mean preoperative best corrected visual acuity was 1.260±0.771 logMAR, and postoperative best corrected visual acuity was 0.352±0.400 logMAR units. Mean vision gain was 0.909 logMar units. The patients had the following complications: 1 retinal detachment was found in one patient, 2 corneal edema was found in three patients, 3 high intraocular pressure was observed in

    The synoptic evolution and dynamical characteristics of storm "Klaus" (23 and 24 January 2009) are analysed. "Klaus" was an extratropical cyclone which developed over the subtropical North Atlantic Ocean on the 21st January 2009, then moved eastward embedded in the strong westerly flow and experienced a notorious strengthening on the 23rd January. The storm moved into the Bay of Biscay and deepened further before hitting Northern Spain and Southwestern France with gusts of up to 198 km/h. Afterwards, it steered southeastwards across Southern France into Northern Italy and the Adriatic. "Klaus" was the most intense and damaging wind storm in the region in a decade, provoked more than 20 casualties and insured losses of several billion Euros. The evolution of "Klaus" is analysed using two standard cyclone detecting and tracking schemes: a) the vorticity maxima based algorithm originally developed by Murray and Simmonds [1991], adapted for Northern Hemisphere cyclone characteristics [Pinto et al. 2005]; and b) the pressure minima based algorithm first developed for the Mediterranean region [Trigo et al. 1999; 2002] and later extended to a larger Euro-Atlantic region [Trigo 2006]. Additionally, the synoptic and mesoscale features of the storm are analysed. The vorticity based method detects the storm earlier than the pressure minima one. Results show that both tracks exhibited similar features and positions throughout almost all of their lifecycles, with minor discrepancies being probably related to different ways of both methods handling the spatio-temporal evolution of multiple candidates for cyclonic centres. In its strengthening phase, "Klaus" presents deepening rates above 37 hPa/24h, a value that after geostrophically adjusted to the reference latitude of 60°N increases to 44 hPa/24h, implying an exceptional event with bomb characteristics. During maximum intensity change within 24 hours was 1.165hPa/(deglat)2. References: Murray RJ, Simmonds I (1991) Aust

    Phlebotomine sand flies (Diptera: Psychodidae) are insects of medical importance due to the role that some species play in the transmission of leishmaniasis. This work aimed to study some ecological aspects among sand flies fauna inhabiting two different environments: the várzea (lowland Amazonian forest) and terra firme (upland Amazonian forest), both located in Tefé Municipality, Amazonas State, Braziland to detect Leishmania infection in those phlebotomine populations. Sand flies were collected using HP light traps. Collection took place over the course of six months: January, February, April, August, September, and October of 2013. To detect natural infection by Leishmania, DNA samples were extracted from female sand flies and submitted to Polymerase Chain Reaction (PCR) targeting the kDNA gene; Leishmania species were identified by PCR-RFLP targeting the hsp70 gene and genetic sequencing. In all, 5,716 individuals were collected, and 46 species were identified. Trichophoromyia ubiquitalis (3,330 - 58.26%) and Nyssomyia antunesi (661 - 11.26%) were the most abundant species. Species richness was greater in terra firme environments (42 species) than in the várzea environments (22 species), and forests ecotopes (43 species) were richer than peridomiciles (28 species). DNA of Leishmania was found in Th. ubiquitalis and Psychodopygus davisi, both of which inhabit the terra firme environment and sequencing analysis confirmed the presence of Leishmania (Viannia) lainsoni DNA in Th. ubiquitalis in Tefé Municipality. The high abundance of Th. ubiquitalis and Ps. davisi and detection of DNA of Leishmania sp. may indicate that both species could be putative vectors for American Cutaneous Leishmaniasis (ACL) in the terra firme environment of Tefé. The sand fly fauna found in várzea is rich and diverse, exhibiting several species, nevertheless the seasonal hydric stress during part of the year that could influence the local diversity, if compared with other studies

    The south coast of Rio de Janeiro State, in Brazil, is endemic for cutaneous and visceral leishmaniases and is frequently visited by tourists from different parts of the world. Since the complex epidemiology of leishmaniases demands local studies, the goal of this study was to investigate the phlebotomine sand fly fauna and leishmaniases transmission in Ilha Grande, an ecotourism area of Angra dos Reis municipality. Sand fly fauna was sampled in three monitoring stations using HP light traps in domiciles, peridomiciles and forests. Species abundance was evaluated by the Index of Species Abundance. A Leishmania natural infection survey was done using multiplex PCR and dot blot hybridization. During 15 consecutive months of sand fly monitoring, 1093 specimens from 16 species were captured. The potential leishmaniases vectors found were Lutzomyia (Nyssomyia) intermedia, L. migonei, L. (N.) flaviscutellata, L. (Psychodopygus) ayrozai and L. (Lutzomyia) longipalpis. Five species were new records in Ilha Grande: L. (Sciopemyia) microps, L. termitophila, L. firmatoi, L. rupicola and L. (P.) ayrozai. Higher species richness was found inside forest areas, although potential leishmaniases vectors were present in deforested areas, peridomiciles and inside houses. Lutzomyia (N.) intermedia and L. migonei were the most abundant species. Females of L. migonei showed a high rate (10.3%) of natural infection by Leishmania (Viannia) sp., probably Leishmania (V.) braziliensis. The detection of leishmaniases transmission and potential vectors in Ilha Grande is of public health concern, especially because tourists are frequently visiting the island. Besides reinforcing the epidemiological importance of L. (N.) intermedia in Rio de Janeiro State, the role of L. migonei in cutaneous leishmaniasis transmission is highlighted with its high rate of Leishmania natural infection. The finding of L. (L.) longipalpis confirmed the human autochthonous case of visceral leishmaniasis from the

    Centriole elimination is an essential process that occurs in female meiosis of metazoa to reset centriole number in the zygote at fertilization. How centrioles are eliminated remains poorly understood. Here we visualize the entire elimination process live in starfish oocytes. Using specific fluorescent markers, we demonstrate that the two older, mother centrioles are selectively removed from the oocyte by extrusion into polar bodies. We show that this requires specific positioning of the second meiotic spindle, achieved by dynein-driven transport, and anchorage of the mother centriole to the plasma membrane via mother-specific appendages. In contrast, the single daughter centriole remaining in the egg is eliminated before the first embryonic cleavage. We demonstrate that these distinct elimination mechanisms are necessary because if mother centrioles are artificially retained, they cannot be inactivated, resulting in multipolar zygotic spindles. Thus, our findings reveal a dual mechanism to eliminate centrioles: mothers are physically removed, whereas daughters are eliminated in the cytoplasm, preparing the egg for fertilization. © 2016 Borrego-Pinto et al.

    Spread over complex networks is a ubiquitous process with increasingly wide applications. Locating spread sources is often important, e.g. finding the patient one in epidemics, or source of rumor spreading in social network. Pinto, Thiran and Vetterli introduced an algorithm (PTVA) to solve the important case of this problem in which a limited set of nodes act as observers and report times at which the spread reached them. PTVA uses all observers to find a solution. Here we propose a new approach in which observers with low quality information (i.e. with large spread encounter times) are ignored and potential sources are selected based on the likelihood gradient from high quality observers. The original complexity of PTVA is O(N α ), where α ∈ (3,4) depends on the network topology and number of observers (N denotes the number of nodes in the network). Our Gradient Maximum Likelihood Algorithm (GMLA) reduces this complexity to O (N 2 log (N)). Extensive numerical tests performed on synthetic networks and real Gnutella network with limitation that id's of spreaders are unknown to observers demonstrate that for scale-free networks with such limitation GMLA yields higher quality localization results than PTVA does.

    Resistance or susceptibility of Red Kidney, Pinto and Small White beans (Phaseolus vulgaris) to the alpha, beta, and gamma strains of Colletotrichum lindemuthianum was either confirmed or established. These fungal strains secrete α-galactosidase, β-galactosidase and β-xylosidase when grown on cell walls isolated from the hypocotyls of any of the above bean varieties. These enzymes effectively degrade cell walls isolated from susceptible 5-day old hypocotyls but degrade only slightly the walls isolated from resistant 18-day old hypocotyls. The amounts of the β-galactosidase and β-xylosidase secreted by the 3 fungal strains are relatively low and are approximately equivalent. The secretion of these 2 enzymes is not dependent upon the bean variety from which the hypocotyl cell walls used as a carbon source were isolated. However, the fungal strains secrete greater amounts of α-galactosidase when grown on hypocotyl cell walls isolated from susceptible plants than when grown on walls from resistant plants. Virulent isolates of the fungus, when grown on hypocotyl cell walls isolated from a susceptible plant, secrete more α-galactosidase than do attenuated (avirulent) isolates of the same fungal strain grown under the same conditions. The α-galactosidase secreted by each of the fungal strains is capable of removing galactose from the hypocotyl cell walls of each bean variety tested. Galactose is removed from the cell walls of each variety at the same rate regardless of whether the cell walls were isolated from a susceptible or resistant plant. PMID:16657049

This work analyzed the landscape transformation of Vidoca Stream Watershed in the period from 1500 to 2003. Based on Remote Sensing and GIS techniques it was found that: a Between 1500 and 1953 natural vegetation classes which included Alluvial Semi-decidual Seasonal Forest, Mountainous Semi-decidual Seasonal Forest and Open Arboreal Savannah changed to anthropic fields and grasslands; b From 1954 to 1985, just before the massive urban occupation of the area, there was a short period of regeneration of the Alluvial Semi-decidual Seasonal Forest above the Carvalho Pinto Highway; later on, the grasslands changed to anthropic fields; c From 1986 to 1997, a fast urbanization process occurred and resulted in the replacement of the grassland and anthropic fields by urban constructions; d From 1998 to 2003, with the consolidation of the urbanization process, the urban occupation reached the boundaries of the plateau and the lowlands of the watershed, resulting in soil impermeabilization. The results of this research indicated that the urbanization process was not controlled in spite of restricted legislation and environmental degradation occurred in this studied watershed along of the study period.

    Full Text Available The Atlantic Forest of northeast Brazil hosts a unique biota which is among the most threatened in the Neotropics. Near-total conversion of forest habitat to sugar cane monocultures has left the region's endemic forest-dependent avifauna marooned in a few highly-fragmented and degraded forest remnants. Here we summarise the current status of 16 globally threatened species based on surveys conducted over the last 11 years. We found a bleak situation for most of these species and consider that three endemics: Glaucidium mooreorum (Pernambuco Pygmy-owl, Cichlocolaptes mazarbarnetti (Cryptic Treehunter and Philydor novaesi (Alagoas Foliage-gleaner are most likely globally extinct. Some positive news can, however, be reported for both Leptodon forbesi (White-collared Kite and Synallaxis infuscata (Pinto's Spinetail which may warrant re-evaluation of their respective red list statuses. We outline a road map to prioritise conservation interventions in the region directed at preventing the extinction of this suite of threatened bird species and their companion biota.

    2001-12-01

    An experimental study on the interaction between Taylor bubbles rising through a co-current flowing liquid in a vertical tube with 32 mm of internal diameter is reported. The flow pattern in the bubble's wake was turbulent and the flow regime in the liquid slug was either turbulent or laminar. When the flow regime in the liquid slug is turbulent (i) the minimum distance between bubbles above which there is no interaction is 5D-6D; (ii) the bubble's rising velocity is in excellent agreement with the Nicklin relation; (iii) the experimental values of the bubble length compare well with theoretical predictions (Barnea 1990); (iv) the distance between consecutive bubbles varied from 13D to 16D and is insensitive to the liquid Reynolds number. When the flow regime in the liquid slug is laminar (i) the wake length is about 5D-6D; (ii) the minimum distance between bubbles above which there is no interaction is higher than 25D; (iii) the bubble's rising velocity is significantly smaller than theoretical predictions. These results were explained in the light of the findings of Pinto et al. (1998) on coalescence of two Taylor bubbles rising through a co-current liquid. (orig.)

    Pinto, Maria; Cavallo, Viola; Saint-Pierre, Guillaume

    2014-01-01

    A recent study (Cavallo and Pinto, 2012) showed that daytime running lights (DRLs) on cars create "visual noise" that interferes with the lighting of motorcycles and affects their visual conspicuity. In the present experiment, we tested three conspicuity enhancements designed to improve motorcycle detectability in a car-DRL environment: a triangle configuration (a central headlight plus two lights located on the rearview mirrors), a helmet configuration (a light located on the motorcyclist's helmet in addition to the central headlight), and a single central yellow headlight. These three front-light configurations were evaluated in comparison to the standard configuration (a single central white headlight). Photographs representing complex urban traffic scenes were presented briefly (for 250ms). The results revealed better motorcycle-detection performance for both the yellow headlight and the helmet configuration than for the standard configuration. The findings suggest some avenues for defining a new visual signature for motorcycles in car-DRL environments. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The electron cloud problem needs to be addressed with innovative solutions, particularly in view of the rapidly approaching HL-LHC upgrade. CERN’s Vacuum, Surfaces and Coatings group has greatly improved its amorphous carbon coating technique, which is an alternative to the scrubbing process used so far. This technique is now fully mature and is being used for the vacuum chambers of the SPS magnets and the delicate beam screens of the LHC’s quadrupole triplets.   The violet light is produced by the argon plasma used when sputtering the amorphous carbon. The beam screen is coated in this case using the magnetic field of the quadrupole itself. (Image: Pedro Costa Pinto) We know that conditioning (or “scrubbing”) the beam pipe reduces the avalanche-like creation of secondary electrons from the tube’s walls, thus preventing the formation of unwanted electron clouds. But it has also been observed that scrubbing natur...

    Between 1932 and 1934, the journal Revista Nacional de Educação was published by Rio de Janeiro's National Museum, under the auspices of hte Brazilian Ministry of Education and Public Health and under the direction of Roquette-Pinto. Its main goal was to disseminate information on science, history, and art among a wide-ranging Brazilian public. The articles were written by the intellectuals of the day, many of whom were scientists at the Museu Nacional. The Revista also published translations of excerpts by a number of travelers. Every issue was published at a low cost, with a significant number of copies. The journal was touted as the initiative of a renewed Republic, part of a broader strategy of inaugurating new relations between government and a population to be educated. It defined itself as "a spiritual milestone in the Brazilian nationality" in tune with the ideal of a State whose educational initiatives were meant to constitute a people and a nation.

    Full Text Available Transmission of Leishmania was studied in 27 coffee plantations in the Brazilian State of Minas Gerais. Eighteen females and six males (11.6% of the people tested, aged between 7-65 gave a positive response to the Montenegro skin test. Awareness of sand flies based on the ability of respondents to identify the insects using up to seven predetermined characteristics was significantly greater among inhabitants of houses occupied by at least one Mn+ve individual. Five species of phlebotomine sand fly, including three suspected Leishmania vectors, were collected within plantations under three different cultivation systems. Four of these species i.e., Lu. fischeri (Pinto 1926, Lu. migonei (França 1920, Lu. misionensis (Castro 1959 and Lutzomyia whitmani (Antunes & Coutinho 1939 were collected in an organic plantation and the last of these was also present in the other two plantation types. The remaining species, Lu. intermedia (Lutz & Neiva 1912, was collected in plantations under both the "adensado" and "convencional" systems. The results of this study indicate that transmission of Leishmania to man in coffee-growing areas of Minas Gerais may involve phlebotomine sand flies that inhabit plantations.

    Full Text Available In February 2001, an accidental spill dumped 52,000 litres of diesel oil in Serra do Mar, Paraná state, Brazil, contaminating streams. This study aimed to evaluate if fish communities currently inhabiting environments exposed to the oil spill still showing evidence of spill-related impacts. Ichthyofauna communities were monitored in five rivers located in the region of the spill. Two sites exposed to oil (Meio and Sagrado rivers were considered treatment sites, and three unexposed sites with environmental characteristics similar to the treatment sites (Pinto, Passa Sete and Marumbi rivers were considered control sites. Analysis of water quality parameters indicated that sites within rivers were more similar than sites among rivers. The diversity and species composition of fish communities differed between the treatment and control groups and among the rivers. The distribution and species composition of ichthyofaunal communities likely reflect the environmental characteristics of each river and not related to the environmental contamination resulting from the oil spill.

    Insoluble, soluble and total dietary fiber (DF) were determined in 35 varieties of certified whole seeds (without processing) of cereals (rice, oat, rye, and wheat) and legumes (pea, cowpea, beans, chikpea, lentil and lupine). The enzymatic method of Asp, Johansson and Siljestrom was used, with modifications in relation to time of incubation with alpha amylase, filtration system and volumes of the filtrates. Results were expressed as g/100 g dry weight. Total DF for cereals showed a range from 10.1 (wheat var. Chasqui) to 22.2 (rice var Quella). Rye, var. Tetra Baer and oats var. Pony Baer presented the highest soluble fiber content (3.3 and 3.9, respectively). In legumes, total DF fluctuated between 12.7 (pea, var. yellow) and 36.6 (lupine, var. Multolupa). Bean, var. Pinto INIA and lupine var. Multolupa presented the highest soluble fiber values (5.8 for both). Based on the results of this research work, it might be concluded that great variation exists in regard to the amount of total soluble and insoluble DF in cereals and legumes, a fact which impedes generalization as to its content in each food item.

    1976-07-01

    A report is given of the results accomplished during the third year of a three-year research program, the overall goal of which has been to conceive and evaluate practical ways to increase automobile fuel economy by energy management within the engine-transmission-vehicle system. The third year was devoted primarily to the detailed design, construction, and preliminary evaluation of a Flywheel Energy Management Powerplant (FEMP) installed in a Pinto. The vehicle has been built to experimentally verify performance simulations and to allow the practical aspects of a real flywheel vehicle to be studied. The FEMP consists basically of an internal combustion engine, a high-speed energy-storage flywheel, and a hydrostatic power-split continuously-variable transmission (CVT) system. The flywheel drives the car, and the engine comes on to ''recharge'' it (with efficient wide-open throttle operation) only when the flywheel speed drops below a predetermined value. The concept also permits effective and efficient regenerative braking. Computer simulations have indicated an improvement in city fuel mileage of about 50%, with improvements of 100% appearing feasible with further research. Preliminary testing of the car shows favorable performance.

    Previous research has demonstrated that comorbid obsessive-compulsive personality disorder (OCPD) in patients with obsessive-compulsive disorder (OCD) is associated with greater overall OCD severity, functional impairment, and poorer treatment outcomes (Coles et al., 2008; Lochner et al., 2010; Pinto, 2009). However, research has only examined the effects of OCPD categorically and has yet to thoroughly examine the impact of individual OCPD characteristics dimensionally. Thus, the present study sought to investigate the relationships between various OCPD-related dimensions (e.g., perfectionism, rigidity) and OCD symptomology and severity. The study recruited a sample of OCD patients (n=51) in the OCD units of two residential treatment facilities. Findings yielded significant relationships between OCD severity and the following OCPD dimensions: flexibility, doubts about actions (a dimension of perfectionism), and hoarding. Interpretations of these results and the implications for diagnosis, prognosis, and treatment outcome are discussed. Furthermore, the current study provides insight into a unique perspective which leaves room for more symptom overlap and variability between OCD and OCPD. Published by Elsevier Ltd.

    Experiments were performed with several plant species in natural environments as well in a greenhouse and/or tissue culture facilities to establish dose-response functions of plant responses to simulated acidic rain in order to determine environmental risk assessments to ambient levels of acidic rain. Response functions of foliar injury, biomass of leaves and seed of soybean and pinto beans, root yields of radishes and garden beets, and reproduction of bracken fern are considered. The dose-response function of soybean seed yields with the hydrogen ion concentration of simulated acidic rainfalls was expressed by the equation y = 21.06-1.01 log x where y = seed yield in grams per plant and x = the hydrogen concentration if μeq l -1 . The correlation coefficient of this relationship was -0.90. A similar dose-response function was generated for percent fertilization of ferns in a forest understory. When percent fertilization is plotted on logarithmic scale with hydrogen ion concentration of the simulated rain solution, the Y intercept is 51.18, slope -0.041 with a correlation coefficient of -0.98. Other dose-response functions were generated that assist in a general knowledge as to which plant species and which physiological processes are most impacted by acidic precipitation. Some responses did not produce convenient dose-response relationships. In such cases the responses may be altered by other environmental factors or there may be no differences among treatment means

    Abstract. Duponchelia fovealis Zeller (Lepidoptera: Crambidae is an exotic moth species which has become a key pest of strawberries in Brazil, causing severe damage in leaves and fruits. Insect growth regulators and botanical insecticides are promising chemical groups to control this pest due to their selectivity to natural enemies and to their lower toxicity. The objective of this study was to evaluate the effect of five insect growth regulators and one botanical insecticide on the parasitism and emergence of three Trichogramma species on eggs of D. fovealis in the laboratory, in order to develop pest management strategies. The insecticides utilized in the tests were formulated from Diflubenzuron, Lufenuron, Pyriproxyfen, Methoxyfenozide, Tebufenozide, and Azadirachtin. D. fovealis eggs were immersed for five seconds in each of the chemical mixtures and after one-hour were offered to Trichogramma galloi Zucchi, Trichogramma exiguum Pinto & Platner,or Trichogramma atopovirilia Oatman & Platner for parasitism. The insecticides were tested for their action on the parasitism and emergence of the F1 generation; the chemicals were then classified for their toxicity according to indices proposed by IOBC/WPRS. The insecticides affected parasitism and emergence differently, indicating different tolerances among the three Trichogramma species, and were classified as innocuous or slightly harmful to the three species under evaluation. However, lufenuron was moderately harmful to T. galloi and caused the highest reduction in parasitism by the parasitoid.

    Full Text Available This paper presents a research that investigated the concept of digital literacy in studies published in the Scielo Brazil, Portugal and Spain databases . From the concept as it is presented in the various studies the conceptualization of a critical digital literacy is pursued. This perspective refers directly to human formation in the contemporary world and to the relationship between education and digital citizenship. It considerates the understanding of the concept of technology in its ideological dimension, putting centrality in the condition of the subjects in the digital media. Three categories of analysis are explained by the study - Ideological Representation, Ideological Positioning and Ideological Production that seek to provide analytical subsidies for the state of appropriation of the subject in the perspective of critical digital literacy. The theoretical contribution is anchored in critical social philosophers such as Heidegger (2007, Marcuse (1973, Feenberg (2010, 2012 and especially Vieira Pinto (2005, Brazilian philosopher, among other authors who contributed to the debate and Concepts of technology and digital literacy.

  15. On the age of Gliese 86

    2014-01-01

    Gliese 86 is a nearby planet hosting a visual binary consisting of a K-type primary, Gl 86 A, and a white dwarf secondary, Gl 86 B. In this work, we present a model atmosphere analysis of the M A = 0.83 M ☉ primary, whose chemistry unambiguously identifies it as a 10 Gyr old disk star. For the secondary, this gives rise to a progenitor mass M prog = 1.11 ± 0.05 M ☉ , and—by inference with its local sibling o 2 Eri—a white dwarf mass M B = 0.49 ± 0.02 M ☉ . The discrepancy with the 2-3 Gyr chromospheric age of Gl 86 A, as first noted by Rocha-Pinto, Castilho and Maciel, is thus most plausibly the result of a former accretion of mass and angular momentum from the distant degenerate. In consequence, this also implies that with respect to shorter-period systems, like Sirius or Procyon, one must expect significant wind accretion when they evolve through the planetary nebula phase, such that the system ages cannot be reliably determined from their currently bright primaries.

  16. At the margins of biomedicine: the ambiguous position of 'Registered Medical Practitioners' in rural Indian healthcare.

    This analysis challenges a tendency in public health and the social sciences to associate India's medical pluralism with a distinction between biomedicine, as a homogeneous entity, and its non-biomedical 'others'. We argue that this overdrawn dichotomy obscures the important part played by 'informal' biomedical practice, an issue with salience well beyond India. Based on a qualitative study in rural Andhra Pradesh, South India, we focus on a figure little discussed in the academic literature - the Registered Medical Practitioner (RMP) - who occupies a niche in the medical market-place as an informal exponent of biomedical treatment. We explore the significance of these practitioners by tracking diagnosis and treatment of one increasingly prominent medical 'condition', namely diabetes. The RMP, who despite the title is rarely registered, sheds light on the supposed formal-informal sector divide in India's healthcare system, and its permeability in practice. We develop our analysis by contrasting two distinctive conceptualisations of 'informality' in relation to the state in India - one Sarah Pinto's, the other Ananya Roy's. © 2016 The Authors.

    Over the last decades strong efforts have been made to apply new spaceborn technologies to the study of volcanic activity. Recent studies have shown that the high resolution satellite images can be very useful for tracking of evolution of the stress patterns related to the volcanic activity. It can be done by observing the changes in density and orientation of lineaments extracted from satellite images. A lineament is generally defined as a straight or a somewhat curved feature in the landscape visible in a satellite image as an aligned sequence of pixels of a contrasting intensity compared to the background. The system of lineaments extracted from the satellite images is not identical to the geological lineaments which are usually determined by land-based surveys, nevertheless, it generally reflects the structure of the faults and fractures in the Earth's crust. For this study the lineaments were detected using the ADALGEO software, based on the Hough transform (Soto-Pinto et al, 2013). A temporal sequence of the Landsat 8 multispectral images of the Lascar volcano, located in the North of Chile, was used to study changes in lineament configuration during 2013-2014. It was found that, the number and orientation of lineaments is affected by microseimicity. In particular, it was found that often the density of lineaments decreases with the intensity of microseisms, which could be related to the volcano inflation.

    To evaluate the dietary contribution of culturally preferred foods in a population of Black Seventh-Day Adventists from the eastern and southern United States in order to improve the standard food frequency questionnaire. Intake of such foods was assessed using a specially designed self-administered food frequency questionnaire consisting of a list of 60 items. A demographic questionnaire was administered by later telephone interview. Southern and northeastern United States. One hundred and sixty-one Black Seventh-Day Adventists were selected from 60 congregations. Approximately half had Caribbean roots. Among the special foods included, red beans stood out and were among the top five contributors to eight of nine selected nutrients. Various legumes, cruciferous vegetables, and okra-corn-tomatoes were the most frequently consumed special foods. Macaroni and cheese was an important contributor to total energy, fat, saturated fat, and protein. At least weekly consumption of red beans, rice and beans, pinto beans, black-eyed peas, plantains and poke salad was reported by 47%, 40%, 31%, 28%, 26% and 25% of subjects, respectively. These foods (largely the legumes) contributed 77% and 104% of the dietary reference intakes for folate and total fiber, respectively. On average, all these foods contributed an estimated 726 calories per day. These findings show that, in total, these foods make a major contribution to the diets of these subjects and that the most commonly eaten at least should be included in dietary questionnaires designed for this minority population.

  19. On complicity theory.

    The received account of whistleblowing, developed over the last quarter century, is identified with the work of Norman Bowie and Richard DeGeorge. Michael Davis has detailed three anomalies for the received view: the paradoxes of burden, missing harm and failure. In addition, he has proposed an alternative account of whistleblowing, viz., the Complicity Theory. This paper examines the Complicity Theory. The supposed anomalies rest on misunderstandings of the received view or misreadings of model cases of whistleblowing, for example, the Challenger disaster and the Ford Pinto. Nevertheless, the Complicity Theory is important for as in science the contrast with alternative competing accounts often helps us better understand the received view. Several aspects of the received view are reviewed and strengthened through comparison with Complicity Theory, including why whistleblowing needs moral justification. Complicity Theory is also critiqued. The fundamental failure of Complicity Theory is its failure to explain why government and the public encourage and protect whistleblowers despite the possibility of considerable harm to the relevant company in reputation, lost jobs, and lost shareholder value.

The article discusses the importance of the teaching of sociology at the Brazilian educational thought from the linkage between certain variables such as “democracy”, “science” and “modernity”, and suggests that in texts of Florestan Fernandes, Costa Pinto and Antonio Cândido, for example, there is an association between a conception of democracy, a prospect that is to be studied social relations in Brazil and the prominence of education as a strategic project of modernization and democratic development rightly due to the formation of “skills” needed to Brazilian citizens, where the teaching of sociology at the high school took place of prominence for the project, in a context of effervescent break with a past taken by representative of our delay.

    Iatrogenic pigment dispersion syndrome generally originates from a repetitive, mechanical trauma to the pigmented posterior epithelium of the iris. This trauma can arise after intraocular surgery, most commonly due to an abnormal contact between the intraocular lens (IOL) and the iris. Whether surgical removal of this primary insult can lead to a successful intraocular pressure (IOP) control remains unclear. Case-series. Patients with IOP elevation and clinical signs of pigment dispersion were screened for a diagnosis of iatrogenic IOL-related pigment dispersion. Three patients in which the IOL or the IOL-bag complex caused a pigment dispersion through a repetitive iris chafing were selected. In two cases, replacement of a sulcus-based single-piece IOL (patient 1) or a sub-luxated in-the-bag IOL (patient 2) by an anterior-chamber (AC) iris-fixed IOL led to a sustained decrease in IOP. In the third case, extensive iris atrophy and poor anatomical AC parameters for IOL implantation precluded further surgical intervention. IOL-exchange appears to be a useful tool in the management of iatrogenic pigment dispersion glaucoma due to inappropriate IOL implantation. This cause-oriented approach seems to be effective in controlling IOP, but should be offered only if safety criteria are met. How to cite this article: Van Mierlo C, Abegao Pinto L, Stalmans I.

A period of instability due to a deleterious political intervention (from 1947 to the present day) responsible for the destruction of the structure and concept of a new teaching hospital (Hospital de Santa Maria). As a result of the socio-political situation conflicting law and vicious rules lead to an excess of non-selected teachers and an alarming increase of students, patients and medical doctors. A change from the present situation and a new concept of clinical teaching must be imagined.

  9. Plants as indicators of photochemical oxidants in the USA

    Energy Technology Data Exchange (ETDEWEB)

    Jacobson, J.S.

    1977-01-01

    Plant indicators have been important in identifying the photochemical oxidant problem in the USA since the 1940's. They continue to serve as an inexpensive means of detecting oxidants in the atmosphere and determining the geographical extent and frequency of occurrence of oxidants. Plant indicators are particularly useful for land-use planning and in the evaluation of air pollution effects on agriculture, forestry, and native vegetation. Plant indicators are not satisfactory substitutes for chemical monitoring of the atmosphere because their responses lack specificity and are affected by climatic, edaphic, and cultural factors, as well as the concentration and frequency of occurrence of oxidants. Because they integrate many environmental variables, plant indicators may be valuable models for the response of other species but only to the extent that they respond to oxidants in the same manner as these other species. The four most important factors for the successful use of plant indicators are: genetic uniformity of plant material; standardization of cultural conditions; standardization of procedures for scoring foliar symptoms; and uniformity of climatic and edaphic factors among study sites. The species used most frequently as indicators of oxidants in the US have been Bel W-3 tobacco and Pinto bean for 0/sub 3/ and petunia for peroxyacyl nitrate. 41 references, 1 table.

Os sentidos das posições da Veja são analisados em relação aos quatro casos de corrupção considerados mais relevantes nesse período tendo como base a Análise do Discurso de linha francesa (ORLANDI, 2013 e as contribuições de Céli Pinto (2011 e Jessé Souza (2009. Considera-se que as noções de corrupção presentes na Veja nessas edições tem como base as ideologias do patrimonialismo e do personalismo compreendendo a corrupção como tendo origem no estado em contraposição ao mercado. Desta forma a responsabilidade da corrupção é personificada de forma reducionista em agentes políticos de apenas um partido político.

    Full Text Available Fortune 500 organizations are executing their tasks using projects. Project management is the area of concentration across the world. Different stakeholders have a different perspective about project success. The meaning of project success had been explained in this article. In addition, the Project Critical Success Factors (CSFs were mentioned. The research of Standish Group on project success and project success metrics was presented. Earlier research on the meaning of project success and project critical success factors was highlighted. The works of Jeffery K. Pinto and Dennis P. Slevin, David and Adam, DeLone and McLean, and The Standish Group Research were discussed in this article. The methodology included secondary research based on literature view of prominent empirical studies and the literature reviews by making note of findings and observations from those studies. The initial literature collected led to further search of articles based on their references. The research findings indicate that the top of the most success factors for many projects include project objective, top management commitment, competent project team, and user involvement.

  13. Volatile aldehydes are promising broad-spectrum postharvest insecticides.

    Hammond, D G; Rangel, S; Kubo, I

    2000-09-01

    A variety of naturally occurring aldehydes common in plants have been evaluated for their insecticidal activity and for phytotoxicity to postharvest fruits, vegetables, and grains. Twenty-nine compounds were initially screened for their activity against aphids on fava bean leaf disks. Application under reduced pressure (partial vacuum) for the first quarter of fumigation increased insecticidal activity severalfold. The 11 best aldehydes were assayed against aphids placed under the third leaf of whole heads of iceberg lettuce using the same two-tier reduced-pressure regime, which caused no additional detriment to the commodity over fumigation at atmospheric pressure. Phytotoxicity to naked and wrapped iceburg lettuce, green and red table grapes, lemon, grapefruit, orange, broccoli, avocado, cabbage, pinto bean, and rice at doses that killed 100% of aphids was recorded for three promising fumigants: propanal, (E)-2-pentenal, and 2-methyl-(E)-2-butenal. These three compounds have excellent potential as affordable postharvest insect control agents, killing 100% of the aphids with little or no detectable harm to a majority of the commodities tested. Preliminary assays indicate that similar doses are also effective against mealybugs, thrips, and whitefly.

    Little research has been done to ascertain how patients and families of South Asian origin access and use early intervention mental health services today. The aim of this retrospective study is to gain a better understanding of how well South Asian patients engage with standard psycho-social interventions. In June 2003 an audit was conducted amongst 75 patients from different ethnic groups in Luton. Measures of engagement with mental health services included; number of missed outpatient appointments over one year and compliance with medication regimes. The results of this audit showed that South Asian patients are more likely to miss appointments and refuse to take medication in comparison to their Caucasian or Afro- Caribbean counter-parts. Further analysis revealed that the Bangladeshi subgroup had missed more appointments and had a greater proportion of medication refusal in comparison to the other Asian subgroups. These results support the pioneering work by Dr Robin Pinto in the 1970s he observed that Asian patients perceive and utilise mental health services in a different way compared to the Caucasian population. The observations from our study depict the difficulties in engaging ethnic minority patients into existing services. Hence we argue that future interventions should be adapted and tailored to overcome cultural and language barriers with patients and their families.

Noventa e oito pintos de 1 a 15 dias de vida (normais ou tratados com testosterona inoculados com o T. (S. cruzi foram negativos. Deste modo, dificilmente a refratariedade poderia ser interpretada como decorrência de um "anticorpo natural", uma vez que a bursectomia provoca uma queda na produção de anticorpos e das gamaglobulinas. Em cerca de 50% de ovos embrionados (normais ou tratados com o hormônio foram vistos flagelados do 4º ao 12º dia de inoculação, observando-se ninhos de amastigotos em alguns embriões. Os pintos nascidos dos mesmos grupos dos ovos examinados e positivos, foram sistematicamente negativos pelo exame do sangue. Um deles sacrificado horas depois de nascido, mostrou amastigotos no coração, mas esses parasitos pareciam degenerados. Provavelmente, se alguns chegam a evoluir para tripomastigotos, estes são destruídos á medida que as células hospedeiras se rompem, e assim jamais são encontrados no sangue circulante.It has already been shown that the refractory state of chickens toward "T.

Fifty-four normal newly hatched and inoculated chicks were negative. it has also been verified that this refractory state persists even after hormonal bursectomy (eggs being injected with 2.5 mg of testosterone. Forty-four bursectomized and inoculated newly hatched chicks were negative. If we consider the fact that bursectomy causes a deficiency in the production of antibodies and gammaglobulins, the refractory state seems not to occur on account of a "natural antibody". Inoculations of "T. (S. cruzi" made in 153 eggs (normal or treated with testosterone produced infections of variable intensity in about 50% of them. Although chicks newly hatched from the same groups were always negative. As we have some embryos to be positive until the 21st day of incubation it seems

    Full Text Available Com a criação do Conselho Nacional de Justiça (CNJ em 2004, passou a existir no Judiciário um espaço para reflexão e orientação das práticas e do posicionamento institucional deste Poder. Dentro do escopo do CNJ encontra-se o planejamento das ações promotoras da mudança da imagem do Judiciário, que inclui campanhas publicitárias lançadas desde 2008 pelo CNJ com o intuito de promover uma nova maneira como o Judiciário interage com a sociedade. Este artigo tem por objetivo apresentar como o CNJ utiliza peças publicitárias para construir a imagem institucional do Judiciário diante dos cidadãos. Para tanto, as peças publicitárias oficiais lançadas pelo CNJ foram analisadas com base no método de análise do discurso publicitário proposto por Pinto (2002, que sugere uma abordagem interpretativa, fundamentada na análise de três funções do discurso publicitário: mostração; interação; e sedução. Por meio da análise das peças foi possível oferecer uma interpretação a respeito da proposta de construção de imagem institucional em questão. Fica clara a utilização de dois discursos publicitários que conferem uma base à construção da imagem do Judiciário pelo CNJ: o discurso operacional, que se refere fundamentalmente à divulgação de métodos de prestação jurisdicional que aumentem a celeridade do Judiciário; e o discurso social, que coloca o Judiciário como condutor da discussão de temas controversos, como a punição à violência contra a mulher, a aplicação de penas alternativas e a ressocialização de egressos do sistema prisional, o que claramente evidencia a nova postura do Judiciário.Since the National Council of Justice (CNJ was created, in 2004, there's a space in the Judiciary for reflection and guidance with regard to the practices and institutional positioning of this Power. Within the scope of CNJ, one finds out the planning of actions promoting a change in the Judiciary image, which

Inicialmente foi feito um experimento em câmara climática (A, para se estabelecer padrões de comportamento a partir de limites de temperatura ambiental. Foram alojados 45 pintos em um box de 2,3 m². Uma câmera foi colocada a 2,0 m acima das aves e a captura das imagens foi registrada em um computador. A partir dos padrões determinados no primeiro experimento, foi feita uma avaliação desses resultados em uma granja comercial (experimento B utilizando densidade de aves semelhante, de maneira a possibilitar uma validação. Foram medidas continuamente: a temperatura ambiental e a amplitude e freqüência de ruídos, do grupo de pintos alojados durante a fase de aquecimento em ambos experimentos. Houve correlação entre um padrão de comportamento de agrupamento e a vocalização, medida não somente pela amplitude do ruído do grupo, mas também pelo espectro da sua freqüência. Na etapa de validação observou-se que, mantida a inércia térmica pelo uso adequado de cortinas, as aves vocalizam menos, coincidentemente com a baixa variação súbita de temperatura. Foi possível estimar o bem-estar térmico de pintinhos na fase de aquecimento pelo registro da amplitude e freqüência de ruído do grupo alojado.

The philosophical production of Fernando Savater and Eugenio Trías, who are the most prominent figures of this trend, are studied in an exhaustive way. We demonstrate the presence of a total –in the case of Savater- or a partial break –in Trias case- with academic philosophy, including the most modern tendencies (Analytical Philosophy, Marxist criticism. In Savater’s trajectory the rupture is supported by the reading of Nietzsche provided by the French thinkers belonging to the Collège de Sociologie (Bataille, Klossowski, Cioran essays and the importation of Frankfurt Critical Theory. In constrast, the strategy deployed by Trías consisted in a sort of avantgarde transformation centered in the academic commentary of canonical texts.

    Full Text Available No domínio da produção teórica em psicanálise, há um vasto campo de formulações acerca das manifestações das psicoses na infância e de suas consequências para as suas práticas clínicas. O presente trabalho tem por objetivo a discussão de um caso clínico de psicose na infância, tomando como balizadores as questões relativas à transferência. As concepções psicanalíticas de constituição de sujeito e suas relações com o trabalho na transferência foram brevemente discutidas, sobretudo, a partir do interesse em destacar as particularidades do caso, para então aproximá-las ou distanciá-las das concepções teóricas existentes sobre a psicose na infância. A escrita do presente estudo de caso tem como pano de fundo a experiência no Núcleo de Atenção a Crianças e Adolescentes (NAIA do Hospital de Saúde Mental Professor Frota Pinto em Fortaleza, Ceará, no qual se realizou o atendimento de orientação psicanalítica de uma criança com diagnóstico psiquiátrico de esquizofrenia paranoide. Palavras-chave: Psicose. Clínica. Transferência. Infância. Estudo de caso. In the domain of the theoretical production in Psychoanalysis, there is a wide field of ruminations about childhood psychosis’ manifestations and its consequences to the clinical practice. The following work aims to discuss a clinical case of childhood psychosis, taking as landmarks the questions related to the transference. The psychoanalytical concepts of subject’s constitution and its relations to the clinical practice were briefly discussed for the purpose of highlighting the particularities of the case, in order to approximate or to distinguish them from the existing theoretical concepts on childhood psychosis. According to the case studied, one concludes that the structural delineation allowed a treatment’s handling, which made possible to insert the subject into the transference and thus made possible the treatment itself.

    Full Text Available The chemical composition and energy value of guava and tomato wastes for broilers at different ages were determined in this research. The metabolism assays were carried out by using the methodology of total excreta collection to calculate the chemical composition of wastes collected in different months. A total of 270 COBB broiler chicks was used: 150 in the period from 1 to 8 days of age (phase 1 and 120 chicks were used in the period from 10 to 17 days of age (phase 2. The trials were analyzed as completely randomized design with three treatments with five replications of 10 and 8 birds at the respective ages. The treatments consisted of different diets: one reference diet, one with 30% tomato meal and another with 20% guava meal, both partially replacing the reference diet. The values of the chemical composition of guava and tomato wastes varied according to the collection season. The chemical composition indicated that the wastes can be used in poultry feed, but with high crude fiber contents. The values of apparent metabolizable energy and nitrogen-corrected apparent metabolizable energy and of gross energy metabolizability coefficient of guava waste was not affected by the birds age, different from the result observed for tomato waste, whose digestibility coefficients and apparent metabolizable energy values varied among growing phases. The apparent metabolizable energy values (AME for broilers form 1 to 8 and from 10 to 17 days of age were 1,331 and 1,358 kcal/kg for guava waste and from 2,351 to 2,465 kcal/kg for tomato waste.Objetivou-se determinar a composição química e os valores nergéticos dos resíduos de goiaba e de tomate para frangos de corte em diferentes idades.

    Extreme windstorms are one of the major natural catastrophes in the extratropics, one of the most costly natural hazards in Europe and are responsible for substantial economic damages and even fatalities. During the last decades Europe witnessed major damage from winter storms such as Lothar (December 1999), Kyrill (January 2007), Klaus (January 2009), Xynthia (February 2010), Gong (January 2013) and Stephanie (February 2014) which exhibited uncommon characteristics. In fact, most of these storms crossed the Atlantic in direction of Europe experiencing an explosive development at unusual lower latitudes along the edge of the dominant North Atlantic storm track and reaching Iberia with an uncommon intensity (Liberato et al., 2011; 2013; Liberato 2014). Results show that the explosive cyclogenesis process of most of these storms at such low latitudes is driven by: (i) the southerly displacement of a very strong polar jet stream; and (ii) the presence of an atmospheric river (AR), that is, by a (sub)tropical moisture export over the western and central (sub)tropical Atlantic which converges into the cyclogenesis region and then moves along with the storm towards Iberia. Previous studies have pointed to a link between the North Atlantic Oscillation (NAO) and intense European windstorms. On the other hand, the NAO exerts a decisive control on the average latitudinal location of the jet stream over the North Atlantic basin (Woollings et al. 2010). In this work the link between North Atlantic explosive cyclogenesis, atmospheric rivers and large scale atmospheric variability modes is reviewed and discussed.

No primeiro texto, Claude Zilberberg (Sorbonne e CNRS examina a interdependência entre discurso e acontecimento. O conceito de acontecimento é caro a certa vertente de estudos filosóficos franceses, mormente em Badiou, retomado por Zizek e outros autores.

    Full Text Available Avian metapneumovirus (aMPV is a respiratory pathogen associated with the swollen head syndrome (SHS in chickens. In Brazil, live aMPV vaccines are currently used, but subtypes A and, mainly subtype B (aMPV/A and aMPV/B are still circulating. This study was conducted to characterize two Brazilian aMPV isolates (A and B subtypes of chicken origin. A challenge trial to explore the replication ability of the Brazilian subtypes A and B in chickens was performed. Subsequently, virological protection provided from an aMPV/B vaccine against the same isolates was analyzed. Upon challenge experiment, it was shown by virus isolation and real time PCR that aMPV/B could be detected longer and in higher amounts than aMPV/A. For the protection study, 18 one-day-old chicks were vaccinated and challenged at 21 days of age. Using virus isolation and real time PCR, no aMPV/A was detected in the vaccinated chickens, whereas one vaccinated chicken challenged with the aMPV/B isolate was positive. The results showed that aMPV/B vaccine provided a complete heterologous virological protection, although homologous protection was not complete in one chicken. Although only one aMPV/B positive chicken was detected after homologous vaccination, replication in vaccinated animals might allow the emergence of escape mutants.O Metapneumovírus aviário (aMPV é um patógeno respiratório associado à síndrome da cabeça inchada (SHS em galinhas. Apesar de vacinas vivas contra o aMPV serem utilizadas no Brasil, os subtipos A e B (aMPV/A e aMPV/B são ainda encontrados no país, com predominância do subtipo B. Este estudo foi conduzido com o intuito de estudar dois isolados brasileiros de aMPV (subtipos A e B isolados de frango. Para isto, um desafio experimental em frangos foi conduzido com o intuito de explorar a capacidade de replicação dos subtipos A e B Brasileiros. Posteriormente, a protecção virológica conferida por uma vacina do subtipo B em pintos foi realizada

Minneapolis: University of Minnesota Press, 2009. xxvii + 242 pp. (Paper US$ 22.50 [First paragraph] Over the last ten years the field of Caribbean Studies has seen a precipitous expansion of work on sexualities, as recent review essays by Jenny Sharpe and Samantha Pinto (2006 and Kamala Kempadoo (2009 have observed. The three books under review here, all based on dissertation research and all published in 2009, make important contributions to this growing literature. While each one approaches sexual politics from a distinctive disciplinary, geographic, and theoretical vantage point, all three ask readers to take seriously the central place that sexual desires and practices occupy in the lives of Caribbean people, both at home and in the diaspora. Caribbean sexuality studies are still sometimes thought of as belonging to a domain outside of, or auxiliary to “real” politics, but these studies demonstrate without hesitation how sexuality functions as an important prism through which we might understand broader debates about ethics, politics, and economics in the region. Building from the insights of feminist theorists who connect the “private” realm to community, national, and global geopolitics, they show that sex is intimately connected to certain freedoms – be they market, corporeal, or political – as well as to their consequences. Taken together, they consider sexual subjectivity, political economy, and cultural production in unexpected ways and point to exciting new directions for the

    Full Text Available Artificial ecotopes of 121 peridomiciliary environments in four rural localities in the state of Ceará, Brazil, were studied and the type of material of the ecotopes was identified as triatomine infestation. Two thousand two hundred and four Triatoma brasiliensis Neiva, 340 Triatoma pseudomaculata Corrêa and Espínola, 121 Rhodnius nasutus Stall, and 5 Panstrongylus lutzi (Neiva and Pinto were captured. Out of the 323 ecotopes found (X =2.0 ± 1.8 per dwelling such as pigpens, henhouses, corrals, perches, dovecotes, piles of roofing tiles, bricks, wood, and straw 30.3% were infested by triatomines in all different developmental stages, including eggs. A substantial number of triatomines were found in perches, however the largest infestation took place in roofing materials used in the construction of goat/sheep corrals, henhouses, and pigpens, where 98% of them were captured: 1372 triatomines were located in the roofing tile covers, 285 in the straw, 187 in the perches, 77 in the coverings of roofing tiles and straw, and 13 in the straw and wood. Among all the different pile of materials, roofing tiles were the most infested (50% followed by bricks (38.9% and woods (36.1%. T. brasiliensis colonized mainly brick piles (chi2=16.539; p < 0.05 and roofing tiles (chi2=5,090.58; p < 0.05; T. pseudomaculata preferred wood perches (chi2= 472.39; p < 0.05 and woodpiles (chi2=126.0 p < 0.05, and R. nasutus was principally found in roofing straw (chi2=384.43; p < 0.05. These findings suggest that triatomines tend to colonize peridomiciliary ecotopes similar to their original habitats.

    Full text: Lamellar phases and vesicles composed of lipids have been used as model systems to investigate biological process related to cell membrane as well as promising carriers for drugs and gene therapy. The composition of the membrane determines its three dimensional shape and its properties such as rigidity and compressibility which play an important role on membrane fusion, protein adhesion, interactions between proteins, etc. We present systematic study of a lamellar system composed mainly of lecithin which is a biocompatible phospholipid and simusol, which is a mixture of fatty acids that acts as a cosurfactant introducing flexibility to the membrane. Using X ray scattering we determine the lamellar periodicity as a function of the hydration for different formulations of the membrane; ranging from 100 % to 50 % mass fraction of lecithin. The X-ray spectra are fitted using a 4 Gaussian model [1]that allows us to determine the lamellar periodicity and the Caille parameter [2]. The ideal swelling law relating the membrane volume fraction (φ m ) to the lamellar periodicity (D) is given by φ m =δ m /D, where δ m is the thickness membrane, however, when steric interactions are dominant with respect to electrostatic and van der Waals interactions, deviations from this behavior are expected [3]. We present experimental data illustrating the swelling behavior for the membrane compositions and the respective behavior of the hydration limit, membrane Luzzati [4], of the Caille parameter and qualitative interpretation of the interaction forces the systems studying the parameter membrane square amplitude fluctuation[5].

    Wind energy potential in Iberia is assessed for recent-past (1961-2000) and future (2041-2070) climates. For recent-past, a COSMO-CLM simulation driven by ERA-40 is used. COSMO-CLM simulations driven by ECHAM5 following the A1B scenario are used for future projections. A 2 MW rated power wind turbine is selected. Mean potentials, inter-annual variability and irregularity are discussed on annual/seasonal scales and on a grid resolution of 20 km. For detailed regional assessments eight target sites are considered. For recent-past conditions, the highest daily mean potentials are found in winter over northern and eastern Iberia, particularly on high-elevation or coastal regions. In northwestern Iberia, daily potentials frequently reach maximum wind energy output (50 MWh day-1), particularly in winter. Southern Andalucía reveals high potentials throughout the year, whereas the Ebro valley and central-western coast show high potentials in summer. The irregularity in annual potentials is moderate (2 MWh day-1). The northward displacement of North Atlantic westerly winds (autumn-spring) and the strengthening of easterly flows (summer) are key drivers of future projections.

    Host-foraging responses to different intra- and interpatch densities were used to assess three Trichogramma spp. (Hymenoptera: Trichogrammatidae) Trichogramma deion Pinto and Oatman, T. ostriniae Pang and Chen, and T. pretiosum Riley - as potential biological control agents for the Indian meal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae). Single naïve females were allowed 6 h to forage in Plexiglas arenas with four different spatial arrangements of host eggs, nine single-egg patches), nine four-egg patches, 36 single-egg patches, and 36 four-egg patches. No significant differences were found among species in the number of patches parasitized. As expected, all three species parasitized the most eggs in the 36 four-egg patch treatment and the least in the nine single-egg patch treatment. T. deion parasitized significantly more eggs than T. pretiosum on the nine four-egg patches. T. ostriniae parasitized significantly more patches when intrapatch density was greater, regardless of interpatch density. In contrast, T. deion only parasitized more patches at the greater intrapatch density when the interpatch density was low. Patch density had no effect on T. pretiosum. The spatial pattern of parasitism was more aggregated for T. deion and T. ostriniae in the 36 four-egg patches treatment compared to the 36 single-egg patches treatment. Therefore, intrapatch density was more important than interpatch density for T. ostriniae, and potentially for T. deion, but not for T. pretiosum. T. deion may be the best candidate for augmentative biological control because it parasitized either slightly or significantly more eggs than the other two species in all four treatments. Furthermore, the pattern of parasitism by T. deion in the 36 four-egg patches treatment was the most aggregated among the three species, suggesting a more thorough searching pattern. In contrast, T. pretiosum had the least aggregated pattern of parasitism and therefore may have used a more

    Full Text Available Next generation sequence data provides valuable information and tools for genetic and genomic research and offers new insights useful for marker development. This data is useful for the design of accurate and user-friendly molecular tools. Common bean (Phaseolus vulgaris L. is a diverse crop in which separate domestication events happened in each gene pool followed by race and market class diversification that has resulted in different morphological characteristics in each commercial market class. This has led to essentially independent breeding programs within each market class which in turn has resulted in limited within market class sequence variation. Sequence data from selected genotypes of five bean market classes (pinto, black, navy, and light and dark red kidney were used to develop InDel-based markers specific to each market class. Design of the InDel markers was conducted through a combination of assembly, alignment and primer design software using 1.6x to 5.1x coverage of Illumina GAII sequence data for each of the selected genotypes. The procedure we developed for primer design is fast, accurate, less error prone, and higher throughput than when they are designed manually. All InDel markers are easy to run and score with no need for PCR optimization. A total of 2,687 InDel markers distributed across the genome were developed. To highlight their usefulness, they were employed to construct a phylogenetic tree and a genetic map, showing that InDel markers are reliable, simple, and accurate.

    Within the south-western Mojave Desert, the Joshua Basin Water District is considering applying imported water into infiltration ponds in the Joshua Tree groundwater sub-basin in an attempt to artificially recharge the underlying aquifer. Scarce subsurface hydrogeological data are available near the proposed recharge site; therefore, time-domain electromagnetic (TDEM) data were collected and analysed to characterize the subsurface. TDEM soundings were acquired to estimate the depth to water on either side of the Pinto Mountain Fault, a major east-west trending strike-slip fault that transects the proposed recharge site. While TDEM is a standard technique for groundwater investigations, special care must be taken when acquiring and interpreting TDEM data in a twodimensional (2D) faulted environment. A subset of the TDEM data consistent with a layered-earth interpretation was identified through a combination of three-dimensional (3D) forward modelling and diffusion time-distance estimates. Inverse modelling indicates an offset in water table elevation of nearly 40 m across the fault. These findings imply that the fault acts as a low-permeability barrier to groundwater flow in the vicinity of the proposed recharge site. Existing production wells on the south side of the fault, together with a thick unsaturated zone and permeable near-surface deposits, suggest the southern half of the study area is suitable for artificial recharge. These results illustrate the effectiveness of targeted TDEM in support of hydrological studies in a heavily faulted desert environment where data are scarce and the cost of obtaining these data by conventional drilling techniques is prohibitive.

    Full Text Available Norms for a battery of instruments, including Denckla's and Garfield's tests of Motor Persistence, Benton's Right-Left Discrimination, two recall modalities (Immediate and Delayed of the Bender Test, Wechsler's Digit Span, the Color Span Test and the Human Figure Drawing Test, were developed for the neuropsychological assessment of children in the greater Rio de Janeiro area. Additionally, the behavior of each child was assessed with the Composite Teacher Rating Scale (Brito GNO and Pinto RCA (1991 Journal of Clinical and Experimental Neuropsychology, 13: 417-418. A total of 398 children (199 boys and 199 girls balanced for age with a mean age of 9.3 years (SD = 2.8, who were attending a public school in Niterói, were the subjects of this study. Gender and age had significant effects on performance which depended on the instrument. Nonachievers performed worse than achievers in most neuropsychological tests. Comparison of our data to the available counterparts in the United States revealed that American children outperformed Brazilian children on the Right-Left Discrimination, Forward Digit Span, Color Span and Human Figure Drawing Tests. Further analysis showed that the neurobehavioral data consist of different factorial dimensions, including Human Body Representation, Motor Persistence of the Legs, Orbito-Orobuccal Motor Persistence, Attention-Memory, Visuospatial Memory, Neuropsychomotor Speed, Hyperactivity-Inattention, and Anxiety-Negative Socialization. We conclude that gender and age should be taken into account when using the normative data for most of the instruments studied in the present report. Furthermore, we stress the need for major changes in the Brazilian public school system in order to foster the development of secondary cognitive abilities in our children

  2. Composite harm to plants by sulfurous acid gas and oxidant

    1971-01-01

    The composite effects on plants of sulfur dioxide and ozone, SO/sub 2/ and PAN, SO/sub 2/ and nitrogen dioxide, and NO/sub 2/ and ozone were studied. Pinto bean plants were exposed to SO/sub 2/ or O/sub 3/ only, to each gas alternately, and to a mixture of the two. The degree of injury by the gas or gases was indicated in percentage by area of the leaves damaged. In cases where no geometric effect occurred the damage to the plant by the individual gas had been great; damage from the individual gas had been slight in these cases where such an effect was observed. The geometric effect is produced when the density of SO/sub 2/ is rather low, generally 0.05-0.25 ppm. A mixture of SO/sub 2/ and O/sub 3/ was applied to a tabacco plant; it affected fully grown leaves. In experiments on the composite effects of SO/sub 2/ and PAN on bean, tomato and pepper plants, PAN affected mainly young leaves while SO/sub 2/ affected mature ones. These effects were arithmetric rather then geometric. The SO/sub 2/ and NO/sub 2/ were also studied in the same manner. When SO/sub 2/ and NO/sub 2/ were mixed, a geometric effect was conspicuous in damage to vegetables, the symptoms of damage by either of the two appeared about the same, younger leaves being affected less. When treated with the two gases alternately, the damage was greater if the plants were first treated with NO/sub 2/; possible causes for this effect are discussed. No significant composite effect of NO/sub 2/ and O/sub 3/ was observed.

    Mercury-containing industrial waste has been released into the coastal waters of the Eighth Region of Chile for around two decades. This study, carried out from 1991 to 1993, sought to measure mercury concentrations in the hair of pregnant and lactating women from villages near the coast and in the interior of the region in order to examine the relationship between the concentration of mercury and seafood consumption. The survey questionnaire used in 1991 to determine seafood consumption did not ask about the frequency of consumption of fish, shellfish, and algae but only whether the women who were pregnant or breast-feeding consumed a minimum of one fish-based meal per week. The questionnaire used in 1992 and 1993 asked about the daily and weekly consumption of seafood in general (fish, shellfish, and algae). Spectrophotometry was used to determine the total mercury concentration in samples of 100 mg of hair from 153 pregnant and lactating women in 11 fishing villages of the Eighth Region where seafood is regularly consumed. None of the women had occupational exposure to mercury. Total mercury concentration was also determined in hair samples from a control group composed of 26 pregnant and lactating women from Pinto and El Carmen, villages in the interior of the same region where seafood was rarely eaten. The arithmetic mean of the total mercury concentration in hair was 1.81 mg/kg of body weight for the study group (standard deviation [SD] 1.52) and 0.42 mg/kg for the control group (SD 0.15)--a statistically significant difference (P mercury concentration in hair was significantly higher in women who indicated that they ate fish seven or more times per week; in those who said they ate fish, shellfish, or algae five or more times per week; and in those who had lived 20 or more years in their village. No statistically significant differences were found when the results were analyzed by age.

    Full Text Available Bean rust, caused by Uromyces appendiculatus, is a devastating disease of common bean (Phaseolus vulgaris in the Americas and Africa. The historically important Ur-3 gene confers resistance to many races of the highly variable bean rust pathogen that overcome other rust resistance genes. Existing molecular markers tagging Ur-3 for use in marker-assisted selection produce false results. Here, we describe the fine mapping of the Ur-3 locus for the development of highly accurate markers linked to Ur-3. An F2 population from the cross Pinto 114 (susceptible × Aurora (resistant with Ur-3 was evaluated for its reaction to four different races of U. appendiculatus. A bulked segregant analysis using the SNP chip BARCBEAN6K_3 placed the approximate location of Ur-3 in the lower arm of chromosome Pv11. Specific SSR and SNP markers and haplotype analysis of 18 sequenced bean varieties positioned Ur-3 in a 46.5 kb genomic region from 46.96 to 47.01 Mb on Pv11. We discovered in this region the SS68 KASP marker that was tightly linked to Ur-3. Validation of SS68 on a panel of 130 diverse common bean cultivars containing all known rust resistance genes revealed that SS68 was highly accurate and produced no false results. The SS68 marker will be of great value in pyramiding Ur-3 with other rust resistance genes. It will also significantly reduce time and labor associated with the current phenotypic detection of Ur-3. This is the first utilization of fine mapping to discover markers linked to rust resistance in common bean.

    Cardiovascular dysfunction is highly comorbid with mood disorders, such as anxiety and depression. However, the mechanisms linking cardiovascular dysfunction with the core behavioral features of mood disorder remain poorly understood. In this study, we used mice bearing a knock-in sarcomeric mutation, which is exhibited in human hypertrophic cardiomyopathy (HCM), to investigate the influence of HCM over the development of anxiety and depression. We employed behavioral, MRI, and biochemical techniques in young (3-4 mo) and aged adult (7-8 mo) female mice to examine the effects of HCM on the development of anxiety- and depression-like behaviors. We focused on females because in both humans and rodents, they experience a 2-fold increase in mood disorder prevalence vs. males. Our results showed that young and aged HCM mice displayed echocardiographic characteristics of the heart disease condition, yet only aged HCM females displayed anxiety- and depression-like behaviors. Electrocardiographic parameters of sympathetic nervous system activation were increased in aged HCM females vs. controls and correlated with mood disorder-related symptoms. In addition, when compared with controls, aged HCM females exhibited adrenal gland hypertrophy, reduced volume in mood-related brain regions, and reduced hippocampal signaling proteins, such as brain-derived neurotrophic factor and its downstream targets vs. controls. In conclusion, prolonged systemic HCM stress can lead to development of mood disorders, possibly through inducing structural and functional brain changes, and thus, mood disorders in patients with heart disease should not be considered solely a psychologic or situational condition.-Dossat, A.

    The aim of this paper is to show the stratigraphic record of the Late Pleistocene corresponding to the distal region of the Paraná River basin. It displays sedimentological, paleontological and geochronological evidences that characterise the last interglacial-glacial cycle. In particular, strong environmental records are shown for the Last Interglacial Stage (LIS). Salto Ander Egg Formation (SAEF) is defined as a new lithostratigraphic unit representative of the Late Pleistocene in southwestern Mesopotamia. This unit is formed of complex fluvial deposits, which contains a heterogeneous collection of sub-environments, of ages ranging from 120 to 60 ky BP. The clast-supported gravel facies containing sparse boulders indicate high flow during a humid climate. The large and middle-scale architectures of fluvial sedimentary bodies evidence the relationship between the sediment accommodation and the sea level oscillations. Three sub-sequences identified in the succession suggest a transgressive trend during the MIS5e, a highstand stage in MIS5c, and a minor transgressive cycle during MIS3. A Brazilian faunal association collected at the bottom of the sequence and sedimentological interpretations display wet and warm climatic conditions, typical of tropical or subtropical environments. Such environmental conditions are characteristic of the maximum of the last interglacial stage (MIS5e) and show a signal stronger than the signal of the current interglacial stage. All these data show a direct correlation between the increases of paleodischarges and the elevation of the sea level. The whole sequence is completed with transitional swampy deposits, accumulated probably during the MIS3/MIS2 transition, and the typical loess of the Tezanos Pinto Formation, mantled during the Last Maximum Glacial.

Para isso, consideramos a performance vocal como instrumento de compreensão do texto poético, a despeito de hoje preponderar o uso do suporte impresso para sua publicação. Acreditamos que, na medida em que a feitura do poema implica a manipulação da materialidade sonora da palavra, a sua leitura precisa recorrer à escuta de uma voz, ainda que apenas como virtualidade. Constatamos, no entanto, que a realização vocal não dá a conhecer apenas o ritmo, o andamento e a entoação do verso; por meio dela, evidencia-se a presença da subjetividade que se manifesta na composição lírica. Nesse ponto, torna-se importante a observação de que a poesia abriga no mundo contemporâneo uma diversidade de configurações dadas por um sujeito criador múltiplo. Considerando isso, tomamos para estudo poemas de poetas contemporâneos, três portugueses, Fiama Hasse Pais Brandão, Ana Luísa Amaral e Manuel de Freitas, e três brasileiros, Francisco Alvim, Neide Archanjo e Claudia Roquette-Pinto. Com base na leitura desses poemas, propomos uma classificação das diferentes ocorrências do princípio subjetivo.

    Full Text Available Guedes-Pinto paste is the filling material most employed in Brazil for endodontic treatment of deciduous teeth; however, the Rifocort® ointment has been removed. Thus, the aim of this study was to investigate the antimicrobial potential of filling pastes, by proposing three new pharmacological associations to replace Rifocort® ointment with drugs of already established antimicrobial power: Nebacetin® ointment, 2% Chlorhexidine Gluconate gel, and Maxitrol® ointment. A paste composed of Iodoform, Rifocort® ointment and Camphorated Paramonochlorophenol (CPC was employed as the gold standard (G1. The other associations were: Iodoform, Nebacetin® ointment and CPC (G2; Iodoform, 2% Chlorhexidine Digluconate gel and CPC (G3; Iodoform, Maxitrol® ointment and CPC (G4. The associations were tested for Staphylococcus aureus (S. aureus, Streptococcus mutans (S. mutans, Streptococcus oralis (S. oralis, Enterococcus faecalis (E. faecalis, Escherichia coli (E. coli, and Bacillus subtilis (B. subtilis, using the methods of dilution on solid medium – orifice agar – and broth dilution. The results were tested using statistical analysis ANOVA and Kruskal-Wallis. They showed that all the pastes had a bacteriostatic effect on all the microorganisms, without any statistically significant difference, compared with G1. S. aureus was statistically significant (multiple comparison test of Tukey, insofar as G2 and G3 presented the worst and the best performance, respectively. All associations were bactericidal for E. coli, S. aureus, S. mutans and S. oralis. Only G3 and G4 were bactericidal for E. faecalis, whereas no product was bactericidal for B. subtilis. Thus, the tested pastes have antimicrobial potential and have proved acceptable for endodontic treatment of primary teeth.

    Norms for a battery of instruments, including Denckla's and Garfield's tests of Motor Persistence, Benton's Right-Left Discrimination, two recall modalities (Immediate and Delayed) of the Bender Test, Wechsler's Digit Span, the Color Span Test and the Human Figure Drawing Test, were developed for the neuropsychological assessment of children in the greater Rio de Janeiro area. Additionally, the behavior of each child was assessed with the Composite Teacher Rating Scale (Brito GNO and Pinto RCA (1991) Journal of Clinical and Experimental Neuropsychology, 13: 417-418). A total of 398 children (199 boys and 199 girls balanced for age) with a mean age of 9.3 years (SD = 2.8), who were attending a public school in Niterói, were the subjects of this study. Gender and age had significant effects on performance which depended on the instrument. Nonachievers performed worse than achievers in most neuropsychological tests. Comparison of our data to the available counterparts in the United States revealed that American children outperformed Brazilian children on the Right-Left Discrimination, Forward Digit Span, Color Span and Human Figure Drawing Tests. Further analysis showed that the neurobehavioral data consist of different factorial dimensions, including Human Body Representation, Motor Persistence of the Legs, Orbito-Orobuccal Motor Persistence, Attention-Memory, Visuospatial Memory, Neuropsychomotor Speed, Hyperactivity-Inattention, and Anxiety-Negative Socialization. We conclude that gender and age should be taken into account when using the normative data for most of the instruments studied in the present report. Furthermore, we stress the need for major changes in the Brazilian public school system in order to foster the development of secondary cognitive abilities in our children.

    Full Text Available In order to investigate the effects of weeds interference on yield and yield components of different genotypes of common bean, an experiment was conducted as split plot based on randomized complete block design with three replications at Agricultural Research Station of Tabriz University, in 2011. The main plots were eight genotypes of different types of common bean including red bean, (cv. Gholi, Sayad, Derakhshan and Akhtar; pinto bean, (cv. Khomein and Sadri and white bean (cv. Shokufa and Pak and the sub-plots were two levels of weed including weed-free and weed-infested. Results indicated that the effect of bean genotype was significant on yield and yield components. The effect of weed treatment was significant on all traits of common bean, except 100-seeds weight. The pod number per plant of all common bean genotypes reduced significantly under weed-infested treatment. The interaction effect of weed treatment× genotype was significant on bean seed number per pod, grain and biological yield. Among the genotype, the cv. Gholi had the highest pod number per plant and the cultivars Gholi and Shokufa had the highest seed number per pod. The cultivars of Gholi and Khomein produced the highest and lowest seed yield, respectively in both weed-free and weed-infested treatment. The common bean genotype showed different competitive ability as the genotypes Gholi and Pak had the higher competitive ability against the weeds than other genotypes. Therefore by cultivating the bean genotypes with high competitive ability against the weeds, the yield loss of common bean could be reduced as well as the growth of weed species will be suppressed.

    To report a case of a patient who developed uveitis-glaucoma-hyphema (UGH) syndrome after an uneventful cataract surgery and to discuss risk factors, diagnostic challenges, management options, and clinical implications. Uveitis-glaucoma-hyphema syndrome is a rare but potentially serious cataract surgery complication. Clinical manifestations include increased intraocular pressure (IOP), anterior chamber inflammation, and recurrent hyphema or microhyphema. Uveitis-glaucoma-hyphema Plus syndrome also includes accompanying vitreous hemorrhage. Although classically associated with rigid anterior chamber intraocular lenses (lOLs), cases of malpositioning and subluxated posterior chamber lOLs have also been described as possible triggers. We report a case of a 70-year-old Caucasian man who developed UGH Plus syndrome after an uneventful cataract surgery with an lOL implanted in the capsular bag. During postoperative follow-up, persistent intraocular inflammation, increased IOP, hyphema, and vitreous hemorrhage were consistent with this diagnosis. Slit-lamp examination demonstrated progressive localized iris atrophy, compatible with chafing of the posterior iris by the IOL haptic as the trigger for UGH syndrome. A pars plana vitrectomy was performed and a retropupillary intraocular lens was implanted. No further complications occurred during follow-up. Given the increasing prevalence of single-piece lOLs implanted in the capsular bag, it is important to recognize UGH syndrome as a rare but potentially serious complication.

    Transparent conductive oxides, such as tin dioxide (SnO{sub 2}), have recently shown to be promising materials for thermoelectric applications. In this work we studied the thermoelectric properties of Fe-, Sb- and Zn-uniformly doping and co-doping SnO{sub 2}, as well as of Sb and Zn planar (or delta)-doped layers in SnO{sub 2} forming oxide superlattices (SLs). Based on the semiclassical Boltzmann transport equations (BTE) in conjunction with ab initio electronic structure calculations, the Seebeck coefficient (S) and figure of merit (ZT) are obtained for these systems, and are compared with available experimental data. The delta doping approach introduces a remarkable modification in the electronic structure of tin dioxide, when compared with the uniform doping, and colossal values for ZT are predicted for the delta-doped oxide SLs. This result is a consequence of the two-dimensional electronic confinement and the strong anisotropy introduced by the doped planes. In comparison with the uniformly doped systems, our predictions reveal a promising use of delta-doped SnO{sub 2} SLs for enhanced S and ZT, which emerge as potential candidates for thermoelectric applications. - Graphical abstract: Band structure and Figure of merit for SnO2:Sb superlattice along Z direction, P.

Development of manual dexterity and finger and hand motor function may be promoted by learning to play the piano. The latter brings together music with the intensive training of hand coordination and fine finger mobility. We investigated if learning to play the piano helped to improve hand motor skills in 18 youths with hand motor disorders resulting from damage during early brain development. Participants trained 35–40 minutes twice a week for 18 months with a professional piano teacher. With the use of a Musical Instrument Digital Interface piano, the uniformity of finger strokes could be objectively assessed from the timing of keystrokes. The analysis showed a significant improvement in the uniformity of keystrokes during the training. Furthermore, the youths showed strong motivation and engagement during the study. This is nevertheless an open study, and further studies remain needed to exclude effects of growth and concomitant therapies on the improvements observed and clarify which patients will more likely benefit from learning to play the piano.

    Full Text Available O experimento foi conduzido nas instalações experimentais da Faculdade de Medicina Veterinária e Zootecnia - UNESP, Campus de Botucatu, SP, Brasil, com o objetivo de avaliar o efeito da densidade de criação e do sexo sobre o empenamento, incidência de lesões na carcaça e a qualidade de carne de peito de frangos de corte. Foram utilizados 1950 pintos de corte sexados, da linhagem Ross, distribuídos em um delineamento inteiramente casualizado, com esquema fatorial com 3 densidades (10, 13 e 16 aves/m² e dois sexos com 5 repetições, sendo que uma foi destinada exclusivamente para reserva, criados até os 42 dias de idade. Aos 28, 35 e 42 dias foram amostradas 3 aves por repetição para a determinação do empenamento através da porcentagem de penas e 10 aves para a determinação do escore de empenamento. Também aos 42 dias de idade todas as aves foram identificadas na pata com anilhas numeradas e submetidas à avaliação da incidência de lesões na pele. Foram escolhidas ao acaso 5 aves por repetição para a determinação da qualidade da carne de peito. Pode-se concluir que o aumento na densidade de criação promoveu uma diminuição na velocidade de empenamento e, conseqüentemente, uma maior incidência de lesões na carcaça. O comprimento, a largura e a espessura do peito foram menores para as aves criadas na maior densidade, e a perda de peso por cozimento foi maior para as aves criadas na maior densidade.

    Full Text Available Este trabalho objetivou determinar o turnover do carbono no Pectoralis major, quilha, tíbia e fígado de frangos de corte em seus diferentes períodos de crescimento, utilizando a técnica dos isótopos estáveis. Foram utilizados 216 pintos de corte, machos, Cobb. O delineamento experimental foi inteiramente casualizado e consistiu de sete tratamentos com dias de substituição das dietas distintos: 0; 7; 14; 21; 28; 35; 42 dias de idade. Para mensurar o turnover do carbono nos tecidos em determinado intervalo de tempo, foi utilizado o modelo sigmoidal de regressão de Boltzmann ou função exponencial do tempo. Os valores de meias-vidas foram: 2,5; 2,8; 2,9; 4,9; 5,1; 5,5 e 6,0 dias para músculo peitoral; 2,7; 2,9; 3,1; 4,6; 5,3; 4,1 e 8,0 dias para quilha; 4,4; 3,6; 5,4; 5,8; 4,3; 5,2 e 6,3 dias para tíbia e 1,3; 1,9; 1,4; 1,5; 1,9; 1,7 e 2,1 dias para fígado, nos tratamentos T1, T2, T3, T4, T5, T6 e T7, respectivamente. Pode-se concluir que a tíbia possui metabolismo lento e pode indicar o sinal isotópico das dietas iniciais da criação dos frangos de corte; e o fígado, metabolismo rápido, indicado para refletir a dieta próxima da fase de avaliação.

    Transparent conductive oxides, such as tin dioxide (SnO_2), have recently shown to be promising materials for thermoelectric applications. In this work we studied the thermoelectric properties of Fe-, Sb- and Zn-uniformly doping and co-doping SnO_2, as well as of Sb and Zn planar (or delta)-doped layers in SnO_2 forming oxide superlattices (SLs). Based on the semiclassical Boltzmann transport equations (BTE) in conjunction with ab initio electronic structure calculations, the Seebeck coefficient (S) and figure of merit (ZT) are obtained for these systems, and are compared with available experimental data. The delta doping approach introduces a remarkable modification in the electronic structure of tin dioxide, when compared with the uniform doping, and colossal values for ZT are predicted for the delta-doped oxide SLs. This result is a consequence of the two-dimensional electronic confinement and the strong anisotropy introduced by the doped planes. In comparison with the uniformly doped systems, our predictions reveal a promising use of delta-doped SnO_2 SLs for enhanced S and ZT, which emerge as potential candidates for thermoelectric applications. - Graphical abstract: Band structure and Figure of merit for SnO2:Sb superlattice along Z direction, P.

    We introduce a deterministic discrete-particle simulation approach, the Linearly-Transformed Particle-In-Cell (LTPIC) method, that employs linear deformations of the particles to reduce the noise traditionally associated with particle schemes. Formally, transforming the particles is justified by local first order expansions of the characteristic flow in phase space. In practice the method amounts of using deformation matrices within the particle shape functions; these matrices are updated via local evaluations of the forward numerical flow. Because it is necessary to periodically remap the particles on a regular grid to avoid excessively deforming their shapes, the method can be seen as a development of Denavit's Forward Semi-Lagrangian (FSL) scheme (Denavit, 1972 [8]). However, it has recently been established (Campos Pinto, 2012 [20]) that the underlying Linearly-Transformed Particle scheme converges for abstract transport problems, with no need to remap the particles; deforming the particles can thus be seen as a way to significantly lower the remapping frequency needed in the FSL schemes, and hence the associated numerical diffusion. To couple the method with electrostatic field solvers, two specific charge deposition schemes are examined, and their performance compared with that of the standard deposition method. Finally, numerical 1d1v simulations involving benchmark test cases and halo formation in an initially mismatched thermal sheet beam demonstrate some advantages of our LTPIC scheme over the classical PIC and FSL methods. Benchmarked test cases also indicate that, for numerical choices involving similar computational effort, the LTPIC method is capable of accuracy comparable to or exceeding that of state-of-the-art, high-resolution Vlasov schemes.

  9. Spontaneous Symmetry-Breaking in a Network Model for Quadruped Locomotion

    Spontaneous symmetry-breaking proves a mechanism for pattern generation in legged locomotion of animals. The basic timing patterns of animal gaits are produced by a network of spinal neurons known as a Central Pattern Generator (CPG). Animal gaits are primarily characterized by phase differences between leg movements in a periodic gait cycle. Many different gaits occur, often having spatial or spatiotemporal symmetries. A natural way to explain gait patterns is to assume that the CPG is symmetric, and to classify the possible symmetry-breaking periodic motions. Pinto and Golubitsky have discussed a four-node model CPG network for biped gaits with ℤ2 × ℤ2 symmetry, classifying the possible periodic states that can arise. A more specific rate model with this structure has been analyzed in detail by Stewart. Here we extend these methods to quadruped gaits, using an eight-node network with ℤ4 × ℤ2 symmetry proposed by Golubitsky and coworkers. We formulate a rate model and calculate how the first steady or Hopf bifurcation depends on its parameters, which represent four connection strengths. The calculations involve a distinction between “real” gaits with one or two phase shifts (pronk, bound, pace, trot) and “complex” gaits with four phase shifts (forward and reverse walk, forward and reverse buck). The former correspond to real eigenvalues of the connection matrix, the latter to complex conjugate pairs. The partition of parameter space according to the first bifurcation, ignoring complex gaits, is described explicitly. The complex gaits introduce further complications, not yet fully understood. All eight gaits can occur as the first bifurcation from a fully synchronous equilibrium, for suitable parameters, and numerical simulations indicate that they can be asymptotically stable.

    The present study investigated the differences in emotional response to automatic thoughts presented during sexual activity between sexually functional and dysfunctional men and women. A total of 376 participants (160 women and 120 men without sexual problems and 47 women and 49 men with a DSM-IV-TR diagnosis of sexual dysfunction) completed the Sexual Modes Questionnaire (SMQ male and female versions; P. J. Nobre & J. Pinto-Gouveia, 2000) and measures of sexual functioning: The International Index of Sexual Function (IIEF; R. C. Rosen et al., 1997), and The Female Sexual Function Index (FSFI; R. C. Rosen et al., 2000). The SMQ is a combined measure constituted by three interdependent subscales: Automatic Thought subscale (AT), Emotional Response subscale (ER), and Sexual Response subscale (SR). Emotions were assessed by the ER subscale, where participants endorsed emotional reactions (worry, sadness, disillusion, fear, guilt, shame, anger, hurt, pleasure, satisfaction) to a list of automatic thoughts (AT subscale) that may occur during sexual activity. Results showed that both men and women with sexual dysfunction had significantly less positive emotional reactions to automatic thoughts during sexual activity. Sexually dysfunctional men had significantly more emotions of sadness, disillusion, and fear, and less pleasure and satisfaction, compared to men without sexual problems. Women with sexual dysfunction had significantly less pleasure and satisfaction, and more sadness, disillusion, guilt, and anger. Findings were congruent with recent studies indicating that emotions related to depressed affect (sadness, disillusion, lack of pleasure) as opposed to negative emotions (mostly related to anxiety) were stronger correlates of sexual dysfunction.

    Full text: Titanium dioxide (TiO{sub 2}) has been extensively studied for applications ranging from dye-solar cells, photo catalysis to sensors [1]. In the present study, TiO{sub 2} nanorod arrays were grown on tracing paper (90 g/cm{sup 2}) under microwave irradiation and without any seed layer. This simple and low temperature synthesis (80 deg C) route formed nanostructures on both sides of the paper, totally covering the flexible substrate. Closely packed nanorod arrays were formed appearing as aggregates with a cauliflower aspect. This nanorod aggregated structure increases the sensitivity due to the large surface area-to-volume ratio, which associated to high quality crystal structure, makes this material as a suitable UV/ozone sensor candidate with high on/off ratios between photo current and dark current. In order to measure the device photocurrent, conductive AFM measurements were carried out, using a 254 nm UV lamp. The dark current displayed 3 times less response than under UV exposure (bias voltage of 5 V). The current-voltage (IV) curves under the UV exposure or dark conditions were also assessed with the deposition of Al contacts and using a probe station. Moreover, the time resolved photocurrent of the devices in response to the UV turn on/off was investigated. Structural characterization of the devices was carried out by scanning electron microscopy (SEM) coupled with X-ray energy dispersive spectroscopy (EDS), Xray diffraction (XRD), together with the investigation of their optical properties. Thus, in association to the recyclability, biocompatible and highly inexpensive characteristics of the substrate used, the approach developed in this study can be a competitive alternative for the UV/ozone sensors employed nowadays.

    The Salton Trough in southern California is a tectonically active pull-apart basin that was formed by migrating step-overs between strike-slip faults, of which the San Andreas Fault (SAF) and the Imperial Fault are the current, northernmost examples. The Salton Seismic Imaging Project (SSIP) was undertaken to improve our knowledge of fault geometry and seismic velocities within the sedimentary basins and underlying crystalline crust around the SAF. Such data are useful as input for modeling scenarios of strong ground shaking in the surrounding high-population areas. We used pre-stack depth migration of line segments from shot gathers in several seismic profiles that were acquired in the northern part of the SSIP study area (Lines 4 - 7). Our migration approach can be considered as an infinite-frequency approximation of the Fresnel volume pre-stack depth migration method. We use line segments instead of the original waveform data. We demonstrate the method using synthetic data and analyze real data from Lines 4 - 7 to illustrate the relationship between distinct phases in the time domain and their resulting image at depth. We show both normal-moveout reflections from sub-horizontal interfaces and reverse-moveout reflections from steep interfaces, such as faults. Migrated images of dipping faults, such as the SAF and the Pinto Mountain Fault, are presented in this way. The SAF is imaged along Line 4, through the Mecca Hills, as a number of steeply dipping fault segments that collectively form a flower structure, above 5 km depth, that sole into a moderately NE-dipping fault below that depth. The individual migrated reflection packages correlate with mapped surface fault traces in the Mecca Hills. A similar geometry is seen on Line 6, from Palm Springs through Yucca Valley, where fault splays sole or project into a moderately dipping SAF below 10-km depth. We also show and discuss the reflectivity pattern of the middle and lower crust for Lines 4 - 7.

In this study, adolescents and adult patients with CP, as well as a group of typically developing children learned to play piano for 4 consecutive weeks, having completed a total of 8 hours of training. For ten of the participants, learning was supported by a special technical system aimed at helping people with sensorimotor deficits to better discriminate fingers and orient themselves along the piano keyboard. Potential effects of piano training were assessed with tests of finger tapping at the piano and tests of perception of vibratory stimulation of fingers, and by measuring neuronal correlates of motor learning in the absence of and after piano training. Results were highly variable especially among participants with CP. Nevertheless, a significant effect of training on the ability to perceive the localization of vibrations over fingers was found. No effects of training on the performance of simple finger tapping sequences at the piano or on motor

    Full Text Available ABSTRACT Green manures are an alternative for substituting or supplementing mineral nitrogen fertilizers. The aim of this study was to quantify biological N fixation (BNF and the N contribution derived from BNF (N-BNF to N levels in leaves of coffee intercropped with legumes grown on four family farms located in the mountainous region of the Atlantic Forest Biome in the state of Minas Gerais, Brazil. The following green manures were evaluated: pinto peanuts (Arachis pintoi, calopo (Calopogonium mucunoides, crotalaria (Crotalaria spectabilis, Brazilian stylo (Stylosanthes guianensis, pigeon pea (Cajanus cajan, lablab beans (Dolichos lablab, and velvet beans (Stizolobium deeringianum, and spontaneous plants. The experimental design was randomized blocks with a 4 × 8 factorial arrangement (four agricultural properties and eight green manures, and four replications. One hundred grams of fresh matter of each green manure plant were dried in an oven to obtain the dry matter. We then performed chemical and biochemical characterizations and determined the levels of 15N and 14N, which were used to quantify BNF through the 15N (δ15N natural abundance technique. The legumes C. mucunoides, S. guianensis, C. cajan, and D. lablab had the highest rates of BNF, at 46.1, 45.9, 44.4, and 42.9 %, respectively. C. cajan was the legume that contributed the largest amount of N (44.42 kg ha-1 via BNF.C. cajan, C. spectabilis, and C. mucunoides transferred 55.8, 48.8, and 48.1 %, respectively, of the N from biological fixation to the coffee plants. The use of legumes intercropped with coffee plants is important in supplying N, as well as in transferring N derived from BNF to nutrition of the coffee plants.

    Full Text Available O hematócrito é uma metodologia indireta utilizada no monitoramento da síndrome ascítica que poderia ser utilizada também para avaliar o peso corporal e características reprodutivas em frangos de corte. Objetivou-se com este trabalho avaliar a técnica do micro-hematócrito em relação ao peso corporal e características reprodutivas (fertilidade, eclodibilidade e nascimento visando sua utilização pelos programas de melhoramento genético. Dois grupos contrastantes foram constituídos, baseados na seleção fenotípica de 630 reprodutores de 18 genótipos para a característica hematócrito. Progênies das aves selecionadas, 74 pintos não sexados (40 do grupo de hematócrito alto e 34 do grupo baixo foram criados com manejo convencional. Os pesos corporais e os valores de hematócrito foram mensurados aos 14 e 42 dias de idade. Para avaliar as características reprodutivas, ovos de 42 matrizes (22 do grupo alto e 20 do baixo foram incubados. As médias foram estimadas utilizando-se um modelo linear com o efeito fixo do grupo genético. Os pintos do grupo baixo apresentaram as maiores médias de peso corporal (305,59 e 1387,06 g, diferindo dos pintos do grupo alto os quais apresentaram médias de peso de 243,56 e 1128,11 g aos 14 e 42 dias de idade, respectivamente. Também para o valor do hematócrito os grupos diferiram significativamente. Para as características reprodutivas, não se verificou diferenças significativas entre os grupos, sendo as médias gerais para fertilidade de 93,8 e 94,9%, para eclodibilidade de 98,2 e 93,9% e para nascimento de 89,3 e 82,4%, respectivamente, para alto e baixo hematócrito. Concluiu-se que a técnica do micro-hematócrito pode ser empregada para avaliação do peso corporal, mas não para características reprodutivas.Hematocrit is an indirect method used to monitor ascites, which might be used also on body weight and reproductive traits evalution in broiler chickens.

    Debo felicitar a las directivas de la Academia por haber propiciado la discusión de una tema de suma trascendencia médica, jurídica, ética y, sobre todo, social. Lástima grande que el pronunciamiento suyo, que ha de salir de esta reunión, no hubiera llegado oportunamente al ámbito de la opinión pública ni al despacho de las autoridades que se han venido ocupando del asunto, tal como lo hicieron otros estamentos, el parlamento, el Ministerio de Salud’, los distintos sectores de la rama jurídica, la Iglesia, los padres de familia, los educadores, etc.; infortunadamente la Academia sigue siendo ignorada por el gobierno. No obstante la tardanza, creo que aún puede tener algún alcance práctico nuestra declaración.

    He leído con la atención debida el acta que registra las intervenciones de los académicos Roberto de Zubiría, Guillermo Sánchez Medina y Mario Camacho Pinto, las tres muy ponderadas y muy inteligentes. El Académico De Zubiría recomienda no utilizar el término “penalizar”, no sé si por no recoger el diccionario de la Real Academia la acepción adecuada para nuestro caso, o por considerar que lo conveniente sea “tratar”, con sentido terapeútico. Los Académicos Sánchez Medina y Camacho Pinto, por su parte, son partidarios de “educar”, adicionándole el Académico Camacho algo de acción represiva.

    Como puede verse, no existe identidad respecto a la manera más conveniente como debe manejarse el problema. Eso es lo que ha ocurrido con los poderes judicial, ejecutivo y legislativo: que existen distintos puntos de vista. En estos casos, lo más adecuado es buscar un punto de equilibrio, que es el que debe pretender la Academia.

    Puntos de vista nuevos han expresado el Académico José Francisco Socarrás, el doctor Eduardo Navarro, el señor Manuel Mancini y el Académico Mario Camacho Pinto.

    Traditionally, human primary visual cortex (V1) has been thought to mature within the first few years of life, based on anatomical studies of synapse formation, and establishment of intracortical and intercortical connections. Human vision, however, develops well beyond the first few years. Previously, we found prolonged development of some GABAergic proteins in human V1 (Pinto et al., 2010). Yet as >80% of synapses in V1 are excitatory, it remains unanswered whether the majority of synapses regulating experience-dependent plasticity and receptive field properties develop late, like their inhibitory counterparts. To address this question, we used Western blotting of postmortem tissue from human V1 (12 female, 18 male) covering a range of ages. Then we quantified a set of postsynaptic glutamatergic proteins (PSD-95, GluA2, GluN1, GluN2A, GluN2B), calculated indices for functional pairs that are developmentally regulated (GluA2:GluN1; GluN2A:GluN2B), and determined interindividual variability. We found early loss of GluN1, prolonged development of PSD-95 and GluA2 into late childhood, protracted development of GluN2A until ∼40 years, and dramatic loss of GluN2A in aging. The GluA2:GluN1 index switched at ∼1 year, but the GluN2A:GluN2B index continued to shift until ∼40 year before changing back to GluN2B in aging. We also identified young childhood as a stage of heightened interindividual variability. The changes show that human V1 develops gradually through a series of five orchestrated stages, making it likely that V1 participates in visual development and plasticity across the lifespan. SIGNIFICANCE STATEMENT Anatomical structure of human V1 appears to mature early, but vision changes across the lifespan. This discrepancy has fostered two hypotheses: either other aspects of V1 continue changing, or later changes in visual perception depend on extrastriate areas. Previously, we showed that some GABAergic synaptic proteins change across the lifespan, but most

    Full text: Lamellar phases and vesicles composed of lipids have been used as model systems to investigate biological process related to cell membrane as well as promising carriers for drugs and gene therapy. The composition of the membrane determines its three dimensional shape and its properties such as rigidity and compressibility which play an important role on membrane fusion, protein adhesion, interactions between proteins, etc. We present systematic study of a lamellar system composed mainly of lecithin which is a biocompatible phospholipid and simusol, which is a mixture of fatty acids that acts as a cosurfactant introducing flexibility to the membrane. Using X ray scattering we determine the lamellar periodicity as a function of the hydration for different formulations of the membrane; ranging from 100 % to 50 % mass fraction of lecithin. The X-ray spectra are fitted using a 4 Gaussian model [1]that allows us to determine the lamellar periodicity and the Caille parameter [2]. The ideal swelling law relating the membrane volume fraction ({phi}{sub m}) to the lamellar periodicity (D) is given by {phi}{sub m} ={delta}{sub m}/D, where {delta}{sub m} is the thickness membrane, however, when steric interactions are dominant with respect to electrostatic and van der Waals interactions, deviations from this behavior are expected [3]. We present experimental data illustrating the swelling behavior for the membrane compositions and the respective behavior of the hydration limit, membrane Luzzati [4], of the Caille parameter and qualitative interpretation of the interaction forces the systems studying the parameter membrane square amplitude fluctuation[5].

    Development of reliable and robust strategies for long-term life support for planetary exploration must be built from real-time experimentation to verify and improve system components. Also critical is incorporating a range of viable options to handle potential short-term life system imbalances. This paper revisits some of the conceptual framework for a Mars base prototype which has been developed by the authors along with others previously advanced ("Mars on Earth ®") in the light of three years of experimentation in the Laboratory Biosphere, further investigation of system alternatives and the advent of other innovative engineering and agri-ecosystem approaches. Several experiments with candidate space agriculture crops have demonstrated the higher productivity possible with elevated light levels and improved environmental controls. For example, crops of sweet potatoes exceeded original Mars base prototype projections by an average of 46% (53% for best crop) ultradwarf (Apogee) wheat by 9% (23% for best crop), pinto bean by 13% (31% for best crop). These production levels, although they may be increased with further optimization of lighting regimes, environmental parameters, crop density etc. offer evidence that a soil-based system can be as productive as the hydroponic systems which have dominated space life support scenarios and research. But soil also offers distinct advantages: the capability to be created on the Moon or Mars using in situ space resources, reduces long-term reliance on consumables and imported resources, and more readily recycling and incorporating crew and crop waste products. In addition, a living soil contains a complex microbial ecosystem which helps prevent the buildup of trace gases or compounds, and thus assist with air and water purification. The atmospheric dynamics of these crops were studied in the Laboratory Biosphere adding to the database necessary for managing the mixed stands of crops essential for supplying a nutritionally

    first nationally representative study of sexuality and multisensory dysfunction in community-dwelling older adults. 4 of the 5 classic senses were measured with objective tests, and hearing was rated by interviewers in the context of their conversation. Medical and health care interventions that can reduce the burden of sensory dysfunction may improve older adults' sexual experience. Sensory dysfunction is associated with sexual inactivity, but not with sexual motivation. Among those who are sexually active, sensory dysfunction did not interfere with sexual expression. Improving the sexual experience of older adults requires a focus on sensory dysfunction as an impediment to sexual activity given that older adults remain sexually motivated.

O pH observado nas carnes de peito e pernas foi maior para os machos (PThe effects of diets with graded levels of SAARA sorghum, a variety containing 0.49g/kg of tannin, on broiler performance and meat quality were evaluated. One-day-old, sexed Ross 308 chicks (n=2600 were randomly assigned within sex to one of five levels of sorghum (replacement of 0, 25, 50, 75 and 100% of corn in the diet. There were 65 birds per experimental unit in 4 replicates of the 5 sorghum level × 2 sex factorial design. Level of corn replacement by sorghum did not affect performance characteristics, carcass characteristics, main cut yield, muscle tissue chemical composition or sensory characteristics of the meat (P>0.05. Muscle tissue from males had higher pH values than that from females, and muscle pH decreased as sorghum replaced corn in the diet (P<0.05. Loin length, width and thickness were larger for males. Breast meat from males had higher cooking loss and required greater shear force than breast meat from females (P<0.05. With increasing level of sorghum in the diet, the L value (level of light of breast and leg muscle increased, whereas a value (redness and b value (yellowness decreased (P<0.05. In summary, replacing corn in the diet with increasing levels of sorghum did not affect live performance, carcass or main cut

The right (contralateral side of the mandible had no ligature placed and was used as control. After the ligature placement, animals were randomly assigned to two experimental groups (n=10: 1 rats with ligature + vehicle (saline; 10 mL/kg; orally and 2 rats with ligature + simvastatin (25 mg/kg; orally. After 14 days of treatment, the animals were euthanized by anesthetic overdose and the gingival tissue was removed and homogenized in appropriate buffer. MMP-2 and -9 release as well as the IL-10 and TNF-α levels were detected by enzyme-linked immunosorbent assay. Statistical comparison was performed by unpaired Student’s t-test, with p<0.05 representing significance.Results: No differences were observed for TNF-α production between the

    Full Text Available O objetivo do experimento foi avaliar os efeitos do tamanho da partícula do fosfato bicálcico (fina ou granulada e dos níveis de fósforo total sobre o desempenho de frangos de corte e sobre os teores de cálcio, fósforo e magnésio dos ossos. O delineamento experimental utilizado foi o inteiramente casualizado em esquema fatorial 3x2 com 3 níveis de fósforo total (0,5%; 0,6% e 0,7% e duas granulometrias de fosfato bicálcico (fina e granulada. Foram utilizados 300 pintos de corte com um dia de idade, machos, da linhagem Cobb, alojados em baterias metálicas em 6 tratamentos com 5 repetições de 10 aves, totalizando 30 gaiolas dispostas em 6 baterias de 5 andares cada. Os resultados demonstraram que o uso do fosfato granulado resultou em melhor desempenho dos animais. Aves alimentadas com o nível de 0,5% de fósforo total apresentaram o pior desempenho, sendo que o nível de 0,6% proporcionou melhor desempenho das aves. As diferentes granulometrias do fosfato, não diferiram estatisticamente quanto a percentagem de matéria mineral, cálcio, fósforo e magnésio nos ossos.The objective of the experiment was to evaluate the effects of particle size of dicalcium phosphate (fine or granulated and of the levels of total phosphorus on the performance of broilers and levels of calcium, phosphorus and magnesium of the bones. Three hundred one-day chicks, males, Cobb strain, were used in an experimental design involving six treatments in a factorial arrangement 2x3 (2 particles size of dicalcium phosphate and 3 phosphorus levels of 0,5%, 0,6% e 0,7%. It was concluded that the addition of granulated dicalcium phosphate resulted in a better performance. The level of 0,5% total phosphorus depressed body weight gain, feed intake and feed conversion and level 0,6% showed better performance. Total bone ash and bone calcium were not affected by treatments, however, better bone phosphorus was found when the broilers received the diet with 0,7% total

    Full Text Available RESUMOObjetivou-se com este trabalho verificar a divergência genética entre sete genótipos de frangos tipo caipira da linhagem Redbro utilizando as características de desempenho por meio de técnicas de análise multivariada. Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. Após a consistência dos dados, foram avaliadas as seguintes variáveis: ganho em peso médio diário, consumo de ração médio diário e conversão alimentar, para os períodos: 1 a 28, 1 a 56, 1 a 70 e 1 a 84 dias de idade; peso corporal ao nascimento, aos 28, 56, 70 e aos 84 dias de idade. O desempenho dos genótipos foi avaliado por meio da análise de variância multivariada e da função discriminante linear de Fisher, usando os testes do maior autovalor de Roy e da união-interseção de Roy para as comparações múltiplas. O estudo da divergência genética foi feito por meio da análise por variáveis canônicas e pelo método de otimização de Tocher. Os genótipos Caboclo e Gigante Negro apresentaram médias canônicas diferentes dos demais genótipos. As duas primeiras variáveis canônicas explicaram 97,41% da variação entre os genótipos. A divergência genética entre os genótipos avaliados permitiu a formação de quatro grupos com os seguintes genótipos: grupo 1 - Colorpak; grupo 2 - Pesadão Vermelho e Pescoço Pelado; grupo 3 - Carijó e Tricolor; e grupo 4 - Caboclo e Gigante Negro.

    Full Text Available RESUMOObjetivou-se com este trabalho comparar o padrão de crescimento, mediante ajustes das respectivas curvas de crescimento por modelos não lineares, bem como estudar o desenvolvimento de cortes de carcaça em relação ao peso da carcaça em diferentes genótipos de frangos tipo caipira. Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos da linhagem Redbro: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. As aves foram alojadas em 28 boxes, sendo 30 aves/boxe, em galpão de alvenaria com acesso a um piquete de 45m², com quatro repetições. O peso corporal individual dos frangos foi medido ao nascer, aos 14, 28, 42, 56, 70 e 84 dias de idade. Para a determinação das curvas de crescimento do peso corporal das aves, os dados coletados foram avaliados por meio dos modelos não lineares: Brody, Gompertz, Logístico, Richards e von Bertalanffy. Foi empregado o PROC NLIN do SAS, utilizando-se o método interativo de Gauss-Newton. Os critérios usados para escolha do modelo de melhor ajuste da curva de crescimento foram o coeficiente de determinação, o desvio padrão assintótico, o desvio médio absoluto dos resíduos e o índice assintótico. As análises para obtenção dos coeficientes alométricos foram realizadas por meio do PROC GLM do SAS para os genótipos Carijó, Colorpak, Pesadão Vermelho, Pescoço P
