Histological and Morphological Study of the Intestines of Wistar Rat Fetuses in a Modified Gastroschisis Experimental Model  [PDF]
André Luis Hecht Sartori, Marina Ferreira Rosa de Vilhena, Gabriela Samaha Frana, Willy Marcus Frana
Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.72010
Abstract: In gastroschisis (G), the lesion degree of exposed intestinal segments is related to the time of its contact with the amniotic fluid (AF) and exposure to meconium which is the cause of intestinal morphological and histological alterations. The outcome of these alterations is intestinal hypoperistalsis and nutrient absorption deficiency, which contribute to increased morbidity and high medical-hospital costs. In this study, morphological and histological intestine alterations were identified at two different contact occasions with AF. Experimental gastroschisis (G) was performed on Wistar rat fetuses at a single gestational age on day 18.5th. The fetuses were removed on the 20.5th (G-1) and 21.5th days (G-2). Fetuses of both groups were divided in 3 sub-groups: control (C), gastroschisis (G) and sham (S). Measurements were taken of the Whole Set including fetus, placenta and membranes with AF (WS), fetus body weight (BW), intestinal weight (IW) and their diameters (DI). The objective of the present study is to test a new gastroschisis experimental model and identify differences in morphological and histological alterations in these two gestational periods that may be directly related to intestinal motility disorders in G. The WS and BW presented no significant statistical difference when compared G1 and G2. The results of the intestine average weight of G2 fetuses were significantly higher when compared to G1 fetuses in all subgroups (C: p = 0.02; G: p = 0.01; S: p = 0.02, Mann Whitney). The results of the intestinal average diameters (D/d) in G1 and G2 presented significant statistical difference only in G subgroup (p < 0.05, Kruskal Wallis). When compared intestinal average diameters, there was significant statistical difference of G fetuses in G1 and G2 (p < 0.05, Mann Whitney). In conclusion, the present experimental G model was adequate to reproduce G in rat fetuses. All G fetuses presented significant statistical difference when compared to other group in their subgroup and when compared G1 and G2 (p < 0.05). These alterations can explain the difficulties in accomplishing adequate peristalsis in G neonate bearers.

International Journal of Geosciences (IJG) , 2012, DOI: 10.4236/ijg.2012.31025
Abstract: The importance of studying the local magnitude related to seismic activity occurred recently in the region of Itacarambi, state of Minas Gerais, is due to the fact that these were earthquakes of intraplate origin. From the study of [1] and the relation between local magnitude and seismic signal duration, was performed a data analysis obtained in the same region, on the period between October/2007 and June/2008, in which we can estimate the equation MD = 2.153 (±0.072) LogD – 1.925 (±0.132) to calculate the magnitude of local duration. We can also estimate one value for the b parameter using the equation LogN = a – bMD from a frequency-magnitude study. It was found the value of b = 0.826 (±0.020) for the general activity of Itacarambi, MG, that is within the universal range proposed by [2].

Physics , 2010, DOI: 10.1111/j.1745-3933.2010.00962.x
Abstract: We study segregation phenomena in 57 groups selected from the 2PIGG catalog of galaxy groups. The sample corresponds to those systems located in areas of at least 80% redshift coverage out to 10 times the radius of the groups. The dynamical state of the galaxy systems was determined after studying their velocity distributions. We have used the Anderson-Darling test to distinguish relaxed and non-relaxed systems. This analysis indicates that 84% of groups have galaxy velocities consistent with the normal distribution, while 16% of them have more complex underlying distributions. Properties of the member galaxies are investigated taking into account this classification. Our results indicate that galaxies in Gaussian groups are significantly more evolved than galaxies in non-relaxed systems out to distances of about 4R200, presenting signficantly redder (B-R) color. We also find evidence that galaxies with M_R < -21.5 in Gaussian groups are closer to the condition of energy equipartition.
Non-Gaussian velocity distributions - The effect on virial mass estimates of galaxy groups
Andre L. B. Ribeiro,Paulo A. A. Lopes,Marina Trevisan
Physics , 2011, DOI: 10.1111/j.1745-3933.2011.01038.x
Abstract: We present a study of 9 galaxy groups with evidence for non-Gaussianity in their velocity distributions out to 4R200. This sample is taken from 57 groups selected from the 2PIGG catalog of galaxy groups. Statistical analysis indicates that non-Gaussian groups have masses significantly higher than Gaussian groups. We also have found that all non-Gaussian systems seem to be composed of multiple velocity modes. Besides, our results indicate that multimodal groups should be considered as a set of individual units with their own properties. In particular, we have found that the mass distribution of such units are similar to that of Gaussian groups. Our results reinforce the idea of non-Gaussian systems as complex structures in the phase space, likely corresponding to secondary infall aggregations at a stage before virialization. The understanding of these objects is relevant for cosmological studies using groups and clusters through the mass function evolution.

Changes of Estuarine Sedimentation Patterns by Urban Expansion: The Case of Middle Capibaribe Estuary, Northeastern Brazil  [PDF]
Roberto Lima Barcellos, Rubens César Lopes Figueira, Elvis Joacir Frana, Carlos Augusto Schettini, Diego de Arruda Xavier
International Journal of Geosciences (IJG) , 2017, DOI: 10.4236/ijg.2017.84027
Abstract: The aim of this study is to describe the sedimentary evolution occurred during the last 200-years in the middle Capibaribe Estuary by mean of the sedimentary analysis (magnetic susceptibility, grain size, calcium carbonate, total organic matter—TOM) and geochemical parameters (sedimentation rates, heavy metal concentrations, enrichment and contamination factor) along a core. The core recorded four units and the measured sedimentation rate was 0.52 cm cm·y1. The first unit, dating before 1812, showed environmental characteristics of mangrove with predominance of fine sediments, high total organic matter percentages and heavy metal concentrations probably from natural sources. The second unit, from 1812 to 1937, showed a slight increase in sand percentages and decrease in fine fraction, TOM contents and heavy metals concentrations. These characteristics may be associated with the urban expansion processes and the presence of monoculture of sugar cane occurred in the middle Capibaribe Estuary. The third unit, from 1937 to 2004, showed the highest sand percentages of the core, characterizing a unit exclusively of sand with low fine fractions percentages, total organic matter contents and heavy metals concentrations. This unit represented the intensification of the urban processes expansion of Recife City. The fourth unit showed increases in fine fraction sedimentation, TOM contents and heavy metals concentrations. This new change in sedimentation probably is consequence of rebirth of marginal estuarine banks by mangrove vegetation, due to environmental projects carried out by Recife Prefecture in the early 2000’s. It was not possible to register the anthropic contamination to middle estuary area probably due to the Barreiras Formation influences in the metal concentration records, masking the anthropic contamination inputs in estuarine region. Although, lead and arsenic showing an enrichment level indicating anthropic contamination.
Avalia??o da suscetibilidade a inseticidas de popula??es da tra?a-das-crucíferas de algumas áreas do Brasil

Abstract: the diamondback moth (dbm) is an important brassica pest and is controlled by several types of insecticides. on some occasions, the fields are sprayed two-four times per week without success. sometimes this occurs because ineffective insecticides are used. works showed that laboratory tests using the recommended field rate of insecticides can detect the ineffective ones. here, we collected dbm larvae and pupae from the states of ceará (tianguá), minas gerais (barroso), bahia (mucugê), mato grosso (sinop) and the federal district (brazlandia and embrapa hortali?as). we reared the populations in the laboratory and larvae of the first laboratory generation were treated with the recommended field rate of abamectin, acephate, b. thuringiensis, cartap, chlorfluazuron, deltamethrin, and spinosad. we previously determined that an effective insecticide should cause more than 90% larval mortality. insecticide effectiveness was different from field to field. spinosad killed 100% of larvae; acephate, b. thuringiensis and cartap killed less than 90% of the larvae in tianguá; abamectin and chlorfluazuron did not control the insect in brazlandia and mucugê respectively. deltamethrin was inneffective in all areas tested. diamondback moth populations were resistant to one or more active ingredients and programmes to manage insecticide resistance must be implemented in brazil.

Abstract: in august 1999, at the "núcleo rural da taquara", federal district, brazil, tomato and brassica crops were severely damaged by the south american tomato pinworm (tuta absoluta) and the diamondback moth (plutella xylostella). during that time growers related that they had been spraying insecticides one to seven times per week without controlling the pests. in the fields it was observed that there were crops with different ages and levels of chemical residues which allowed the pests to multiplicate continuously. then it was decided that the first step to solve the problem would be to evaluate the efficacy of the recommended field rate of some insecticides in laboratory bioassays. two brazilian tomato pinworm populations and one diamondback moth population were collected. cartap, abamectin, lufenuron, acephate and deltamethrin caused 100, 90, 67, 2 and 0% of larval mortality to the south american tomato pinworm, respectively. b. thuringiensis, abamectin, cartap, acephate and deltamethrin caused 100; 96; 86; 79 and 5% of mortality to the diamondback moth, respectively. according to laboratory results it was recommended that the use of pyrethroid and organophosphorous compounds must be suspended immediately. abamectin and cartap must be used to control the south american tomato pinworm and b. thuringiensis must be employed to diamondback moth control.
