Mina53, a novel molecular marker for the diagnosis and prognosis of gastric adenocarcinoma.  

PubMed

Mina53 is a direct novel target protein of Myc. The present study investigated the expression of mina53 and c-myc in gastric carcinoma and the relationship between Mina53 expression and clinicopathological features. The expression levels of mina53 and c-myc mRNA and protein in gastric cancers and the adjacent normal tissues from 12 patients were assessed by laser-capture microdissection (LCM) combined with quantitative polymerase chain reaction (qPCR) and western blotting, respectively. Immunohistochemical analysis was used to evaluate the expression of the Mina53 protein in normal gastric tissues (n=30), chronic atrophic gastritis without intestinal metaplasia (n=44), intestinal metaplasia (n=34), gastric dysplasia (n=36), intestinal-type gastric carcinoma (IGC) (n=30) and diffuse-type gastric carcinoma (DGC) (n=34). The correlation between expression of mina53 and patient survival time was also investigated. The expression levels of mina53 and c-myc mRNA in the gastric carcinomas were found to be higher when compared to these levels in the adjacent normal tissues. In addition, the expression levels of Mina53 and c-Myc protein in gastric carcinomas were higher when compared with levels in the adjacent normal epithelium. mina53 expression was significantly increased during gastric carcinogenesis and was correlated with different clinicopathological factors in IGC and DGC. The prognosis of patients with low expression of Mina53 was more favorable when compared to the prognosis of patients with high expression of Mina53. mina53 expression was gradually elevated during gastric carcinogenesis, and the overexpression of mina53 was correlated with different clinicopathological features between DGC and IGC cases. Furthermore, the prognosis of gastric carcinoma patients was significantly correlated with the expression of Mina53. PMID:24337011

Comparative pollen preferences by africanized honeybees Apis mellifera L. of two colonies in Pará de Minas, Minas Gerais, Brazil.  

PubMed

The aim of this study was to investigate the polliniferous floral sources used by Apis mellifera (L.) (africanized) in an apiary situated in Pará de Minas, Minas Gerais state, and evaluate the pollen prefences among the beehives. Two beehives of Langstroth type with frontal pollen trap collectors were used. The harvest was made from September 2007 to March 2008, with three samples of pollen pellets colected per month per beehive. The subsamples of 2 grams each were prepared according to the European standard melissopalynological method. A total of 56 pollen types were observed, identifying 43 genus and 32 families. The families that showed the major richness of pollen types were: Mimosaceae (8), Asteraceae (6), Fabaceae (3), Arecaceae (3), Euphorbiaceae (3), Rubiaceae (3), Caesalpiniaceae (2), Moraceae (2) and Myrtaceae (2). The most frequent pollen types (> 45%) were Mimosa scabrella, Myrcia and Sorocea. The results demonstrated a similarity regarding the preferences of floral sources during the major part of the time. There was a distinct utilization of floral sources among the pollen types of minor frequency. In spite of the strong antropic influence, the region showed a great polliniferous variety, which was an indicative of the potential for monofloral as well as heterofloral pollen production.

Reactivation of organophosphate-inhibited human acetylcholinesterase by isonitrosoacetone (MINA): a kinetic analysis.  

PubMed

Treatment of poisoning by highly toxic organophosphorus compounds (OP) with atropine and an acetylcholinesterase (AChE) reactivator (oxime) is of limited effectiveness in case of different nerve agents and pesticides. One challenge is the reactivation of OP-inhibited brain AChE which shows inadequate success with charged pyridinium oximes. Recent studies with high doses of the tertiary oxime isonitrosoacetone (MINA) indicated a beneficial effect on central and peripheral AChE and on survival in nerve agent poisoned guinea pigs. Now, an in vitro study was performed to determine the reactivation kinetics of MINA with tabun-, sarin-, cyclosarin-, VX- and paraoxon-inhibited human AChE. MINA showed an exceptionally low affinity to inhibited AChE but, with the exception of tabun-inhibited AChE, a moderate to high reactivity. In comparison to the pyridinium oximes obidoxime, 2-PAM and HI-6 the affinity and reactivity of MINA was in most cases lower and in relation to the most effective reactivators, the second order reactivation constant of MINA was 500 to 3400-fold lower. Hence, high in vivo MINA concentrations would be necessary to achieve at least partial reactivation. This assumption corresponds to in vivo data showing a dose-dependent effect on reactivation and survival in animals. In view, of the toxic potential of MINA in animals human studies would be necessary to determine the tolerability and pharmacokinetics of MINA in order to enable a proper assessment of the value of this oxime as an antidote in OP poisoning.

Potential effects of mina53 on tumor growth in human pancreatic cancer.  

PubMed

Myc-induced nuclear antigen (Mina53) is a protein with a molecular weight of 53 kDa expression of which is induced by c-Myc. Increased expression of Mina53 is documented in some human carcinomas. In this study, we found markedly increased Mina53 expression in pancreatic cancer tissue specimens. This expression did not correlate with clinicopathological characteristics, such as sex, age, and presence of distant metastasis. However, there was a statistically significant association with histological differentiation, TNM stage, and lymph node metastases. To study functional role of Mina53, we silenced its expression by siRNA in PANC-1 cells. These cells were arrested in the G2/M phase, and apoptosis rates were increased. In conclusion, increased expression of Mina53 may play an important role in the development of human pancreatic cancer. Mina53 can be used as a marker for pancreatic cancer and may potentially be exploited as a target for treatment of pancreatic cancer. PMID:24522517

[Schistosomiasis in an ecotourism area in Minas Gerais State, Brazil].  

PubMed

This paper discusses schistosomiasis transmission in São José da Serra, a village with a population of 500 in the county of Jaboticatubas, Minas Gerais State, Brazil. The area receives thousands of visitors a year for ecotourism. The study was motivated by a case of acute schistosomiasis involving a couple that spent the 2007 Carnival (Mardi Gras) holiday in the area. Stool tests from 268 local residents (53.6% of the population) showed that 35 (13%) were positive for the infection. A comparison with a previous survey (2005) in the same location showed an increase in the schistosomiasis-positive rate from 9.6% to 12.5%, among the 56 individuals who participated in both surveys. A malacological survey of 65 Biomphalaria glabrata snails showed one specimen (1.5%) eliminating cercariae. In a similar survey in 2005, no positive snail specimens were found. The study indicates that active schistosomiasis transmission is occurring in the area, and that integrated educational programs are needed for both the local community and tourists. PMID:18670694

Spatial modeling of the schistosomiasis mansoni in Minas Gerais State, Brazil using spatial regression.  

PubMed

Schistosomiasis is a transmissible parasitic disease caused by the etiologic agent Schistosoma mansoni, whose intermediate hosts are snails of the genus Biomphalaria. The main goal of this paper is to estimate the prevalence of schistosomiasis in Minas Gerais State in Brazil using spatial disease information derived from the state transportation network of roads and rivers. The spatial information was incorporated in two ways: by introducing new variables that carry spatial neighborhood information and by using spatial regression models. Climate, socioeconomic and environmental variables were also used as co-variables to build models and use them to estimate a risk map for the whole state of Minas Gerais. The results show that the models constructed from the spatial regression produced a better fit, providing smaller root mean square error (RMSE) values. When no spatial information was used, the RMSE for the whole state of Minas Gerais reached 9.5%; with spatial regression, the RMSE reaches 8.8% (when the new variables are added to the model) and 8.5% (with the use of spatial regression). Variables representing vegetation, temperature, precipitation, topography, sanitation and human development indexes were important in explaining the spread of disease and identified certain conditions that are favorable for disease development. The use of spatial regression for the network of roads and rivers produced meaningful results for health management procedures and directing activities, enabling better detection of disease risk areas.

Alterations to the protein profile of bladder carcinoma cell lines induced by plant extract MINA-05 in vitro.  

PubMed

Bladder cancer (BLCa) is a severe urological cancer of both men and women that commonly recurs and once invasive, is difficult to treat. MINA-05 (CK Life Sciences Int'l, Hong Kong) is a derivative of complex botanical extracts, shown to reduce cellular proliferation of bladder and prostate carcinomas. We tested the effects of MINA-05 against human BLCa cell sublines, B8, B8-RSP-GCK, B8-RSP-LN and C3, from a transitional cell carcinoma, grade IV, to determine the molecular targets of treatment by observing the cellular protein profile. Cells were acclimatised for 48 h then treated for 72 h with concentrations of MINA-05 reflecting 1/2 IC(50), IC(50) and 2 x IC(50) (n = 3) or with vehicle, (0.5% DMSO). Dose-dependant changes in protein abundance were detected and characterised using 2-dimensional electrophoresis and MS. We identified 10 proteins that underwent changes in abundance, pI and/or molecular mass in response to treatment. MINA-05 was shown to influence proteins across numerous functional classes including cytoskeletal proteins, energy metabolism proteins, protein degradation proteins and tumour suppressors, suggesting a global impact on these cell lines. This study implies that the ability of MINA-05 to retard cellular proliferation is attributed to its ability to alter cell cycling, metabolism, protein degradation and the cancer cell environment.

Spatial distribution of Biomphalaria mollusks at São Francisco River Basin, Minas Gerais, Brazil, using geostatistical procedures.  

PubMed

Geostatistics is used in this work to make inferences about the presence of the species of Biomphalaria (B. glabrata, B. tenagophila and/or B. straminea), intermediate hosts of Schistosoma mansoni, at the São Francisco River Basin, in Minas Gerais, Brazil. One of these geostatistical procedures, known as indicator kriging, allows the classification of categorical data, in areas where the data are not available, using a punctual sample set. The result is a map of species and risk area definition. More than a single map of the categorical attribute, the procedure also permits the association of uncertainties of the stochastic model, which can be used to qualify the inferences. In order to validate the estimated data of the risk map, a fieldwork in five municipalities was carried out. The obtained results showed that indicator kriging is a rather robust tool since it presented a very good agreement with the field findings. The obtained risk map can be thought as an auxiliary tool to formulate proper public health strategies, and to guide other fieldwork, considering the places with higher occurrence probability of the most important snail species. Also, the risk map will enable better resource distribution and adequate policies for the mollusk control. This methodology will be applied to other river basins to generate a predictive map for Biomphalaria species distribution for the entire state of Minas Gerais. PMID:19046937

Ticks (Acari: Ixodidae) associated with small terrestrial mammals in the state of Minas Gerais, southeastern Brazil.  

PubMed

From June 2005 to November 2010, 43 small mammals encompassing 6 species of Didelphimorphia, 8 species of Rodentia, and 1 species of Lagomorpha were found parasitized by ticks in the state of Minas Gerais, southeastern Brazil. Nine tick species, in total 186 specimens, were identified as follows: Amblyomma cajennense (larvae and nymphs) on opossums and rodents; Amblyomma ovale (nymphs) on rodents; Amblyomma parvum (nymphs) on rodents; Amblyomma coelebs (nymphs) on opossums; Amblyomma dubitatum (nymph) on opossums; Ixodes amarali (females, nymphs, and larvae) on opossums and rodents; Ixodes loricatus (male, females, nymph) on opossums; Ixodes schulzei (female) on rodents; and Haemaphysalis leporispalustris (female) on rabbits. Most of the tick-host associations found in the present study have never been recorded in the literature; those include three new host records for I. amarali, four for A. cajennense, one for A. dubitatum, two for A. ovale, and one for A. coelebs. In addition, we provide the first record of A. coelebs in the state of Minas Gerais. PMID:22585005

Genetic variability in five populations of Partamona helleri (Hymenoptera, Apidae) from Minas Gerais State, Brazil  

PubMed Central

Partamona is a Neotropical genus of stingless bees that comprises 33 species distributed from Mexico to southern Brazil. These bees are well-adapted to anthropic environments and build their nests in several substrates. In this study, 66 colonies of Partamona helleri from five localities in the Brazilian state of Minas Gerais (São Miguel do Anta, Teixeiras, Porto Firme, Viçosa and Rio Vermelho) were analyzed using nine microsatellite loci in order to assess their genetic variability. Low levels of observed (Ho = 0.099-0.137) and expected (H e = 0.128-0.145) heterozygosity were encountered and revealed discrete genetic differentiation among the populations (F ST = 0.025). AMOVA further showed that most of the total genetic variation (94.24%) in P. helleri was explained by the variability within local populations.

Populational dynamics of Stomoxys calcitrans (Linneaus) (Diptera: Muscidae) in three biocenosis, Minas Gerais, Brazil.  

PubMed

Populational flux of the adult phase of Stomoxys calcitrans was observed in the municipal district of Pedro Leopoldo, Minas Gerais, Brazil. Three biocenoses were selected for the study: stable agrobiocenosis, pastural agrobiocenosis and eubiocenosis. The occurrence and the populational flux of the insects, using the Magoon trap for their capture, were established. For each trap located in different biocenoses, a crossbred calf (Bos taurusxBos indicus) approximately 6-month-old was used as "live bait," exposed weekly for 48h in the traps. Of the three agrobiocenoses studied, the stable agrobiocenosis contributed the greatest number of specimens of. S. calcitrans captured, corresponding to 96.9% of the total flies of this species collected. S. calcitrans shows seasonal behavior for approximately 6 months (spring and summer being the rainiest months of the year). The population peaked during the months of November and December. During the months of July and August, there was no capture of flies. PMID:15908125

[Emerging and reemerging rickettsiosis in an endemic area of Minas Gerais State, Brazil].  

PubMed

This article describes a serological survey for rickettsiosis in the county of Novo Cruzeiro, Minas Gerais State, Brazil, in 1998, testing schoolchildren and dogs. Sera included 331 samples from schoolchildren from an endemic area and 142 samples from schoolchildren from a non-endemic area in the county. All children examined were healthy and had not reported clinical symptoms of Brazilian spotted fever prior to the serological survey. Some 35 children in the endemic area were reactive to Rickettsia rickettsiiby indirect fluorescent antibody (IFA) with a titer of 1:64, corresponding to 10.6%. Sera from 73 dogs were tested, showing seroreactivity (IFA 1:64) to Rickettsia rickettsi, Ehrlichia chaffeensis, and Ehrlichia canisin 3 (4.11%), 11 (15.07%), and 13 (17.81%), respectively. The results in schoolchildren and the presence of canine seroreactivity to Ehrlichiaspecies that are potentially pathogenic to humans suggests the risk of transmission of other Rickettsiaein the study area.

[Biodemes of Trypanosoma cruzi strains isolated from humans from three endemic areas in Minas Gerais State].  

PubMed

In order to study the biological behavior of T. cruzi strains and to determine a putative association between their biodeme and the clinical forms of Chagas disease, 14 strains isolated from humans were evaluated. The individuals were from the municipalities of Pains, Iguatama and Berilo (Minas Gerais State). The biological behavior was evaluated in albino swiss mice, weighing 10 to 15 grams, which were infected with 1x10(4) blood tripomastigotes. The infectivity, parasitemia, tripomastigote morphology, virulence and the tissue distribution of the protozoan were analyzed. A behavior similar to biodeme II (São Felipe strain) was observed in 9 strains, while 5 stocks were characterized as belonging to biodeme III. It was not possible to establish a relationship between the biodeme strain and the severity of the disease in the patients. PMID:12170327

Rocky Mountain spotted fever in an endemic area in Minas Gerais, Brazil.  

PubMed

Only one species of spotted fever-group rickettsiae that is pathogenic for humans has been isolated in Brazil, where few physicians are familiar with this disease. In order to obtain information on tick-borne rickettsiosis, a study was performed in the County of Santa Cruz do Escalvado, State of Minas Gerais, Brazil, where a fatal clinical case confirmed by specific immunofluorescence had been reported. Serum samples obtained from 679 humans and 96 dogs were tested by indirect immunofluorescence for detectable antibodies to spotted fever-group rickettsiae, the criterion for a positive result being a titer > or = 1:64. Seropositivity was detected in 7.14% of the humans sera examined and 13.68% of the dogs. We discuss the significance of these findings and formulate some questions, emphasizing the need for further investigation. PMID:8524052

Landscape structure in the expansion area of deforestation of the Brazilian Cerrado in Minas Gerais  

NASA Astrophysics Data System (ADS)

The Cerrado is the second largest Brazilian biome and is listed as one of the hotspots for biodiversity conservation priority. The biome provides important ecosystem services such as maintenance of the biodiversity, water cycle and carbon storage, and your preservation is essential to protecting the Amazon Rainforest. Although its importance, it was heavily affected by deforestation, with a loss of about 49% of its original native cover by the year of 2010. In Minas Gerais state, the remaining Cerrado original cover is very expressive, shaped by a mosaic of phytophysionomies, comprising grassland, savanna and forest. The great species diversity and endemism in these landscapes, associated with changes imposed by man over time, caused major environmental damage in this biome. Recently, new deforestation fronts have been identified throughout the Brazilian Cerrado, including Minas Gerais State. This study aimed to analyze the landscape structure in front of expansion in this state, as a subsidy for the establishment of guidelines for future biodiversity conservation and landscape planning. The study site comprised the sub basins of the Paracatú River (SF7) and Middle São Francisco (SF9). The analyses were performed based on land use, mapped through remote sensing techniques, resulting in 18 classes of land use. The most important results of the calculated indices showed that the study area is highly fragmented, with most of the remaining patches small, with large perimeter and strong edge effect, favoring biodiversity loss. Moreover, the biological flow in the study area is hindered by the presence of few fragments into a predetermined radius of 10 km. It has been found that less than 30% of the native vegetation remnant in the area, making all existing fragments relevant to conservation. Finally, the landscape metrics analyzed showed that there is a high level of environmental risk determining low support existing biodiversity in the landscape.

Manufacture of low-sodium Minas fresh cheese: effect of the partial replacement of sodium chloride with potassium chloride.  

PubMed

We investigated the effect of sodium reduction by partial substitution of sodium chloride (NaCl) with potassium chloride (KCl) on the manufacture of Minas fresh cheese during 21 d of refrigerated storage. Four treatments of low-sodium Minas fresh cheese were manufactured, with partial replacement of NaCl by KCl at 0, 25, 50, and 75% (wt/wt), respectively. The cheeses showed differences in the content of moisture, ash, protein, salt, and lipid contents, as well as on the extent of proteolysis and hardness throughout the storage period. However, no difference was observed among treatments within each storage day tested. The partial substitution of NaCl by KCl decreased up to 51.8% the sodium concentration of the cheeses produced. The consumer test indicated that it is possible to manufacture a low-sodium Minas fresh cheese that is acceptable to consumers by partial substitution of NaCl by KCl at 25% (wt/wt) in the salting step.

Characteristics of tuberculosis in the state of Minas Gerais, Brazil: 2002-2009*  

PubMed Central

OBJECTIVE: To analyze the profile of tuberculosis cases reported between 2002 and 2009 in the state of Minas Gerais, Brazil, according to sociodemographic, clinical, and laboratory characteristics, as well as to comorbidities and mortality. METHODS: This was a descriptive, epidemiological study based on data obtained from the Brazilian Case Registry Database and the Brazilian Mortality Database for the 2002-2009 period. RESULTS: There were 47,285 reported cases of tuberculosis, corresponding to a mean incidence of 22.3/100,000 population. The individuals diagnosed with tuberculosis were predominantly in the 20- to 49-year age bracket and male (62.4% and 67.0%, respectively). Individuals with a low level of education accounted for 18.5% of the cases. New cases, cases of recurrence, and cases of retreatment accounted for 83.7%, 5.7%, 5.7%, respectively. The rates of cure and treatment noncompliance were 66.2% and 11.2%, respectively; multidrug-resistant tuberculosis was identified in 0.2% of the cases; and the mortality rate was 12.9%. The directly observed treatment, short-course (DOTS) strategy was applied in 21.8% of the cases. Sputum smear microscopy and culture were performed in only 73.9% and 12.9% of the cases, respectively. Chest X-rays were performed in 90.5% of the cases. Pulmonary tuberculosis was the predominant form (in 83.9%). Comorbidity with alcoholism, HIV infection, and diabetes mellitus were identified in 17.2%, 8.3%, and 3.8%, respectively. CONCLUSIONS: During the study period, the numbers of new cases, cases of treatment noncompliance, and deaths were high, comorbidities were common, and there was a failure to perform adequately basic tests for the diagnosis of tuberculosis. Multidisciplinary approaches, expanded use of the DOTS strategy, better knowledge of the distribution of tuberculosis, and improvements in the databases are needed in order to achieve better control of the disease in the state of Minas Gerais.

Isoenzyme variation in Melipona rufiventris (Hymenoptera: Apidae, Meliponina) in Minas Gerais State, Brazil.  

PubMed

The stingless bee Melipona rufiventris is an important pollinator in several Brazilian ecosystems. Originally widely distributed in Minas Gerais (MG) state, this species is becoming very rare. Therefore this species was included in the endangered species list of MG. We used isoenzyme data for a better understanding of the genetic structure of several M. rufiventris colonies. Samples of 35 colonies were collected from 12 localities and evaluated by nine enzymatic systems, which yielded 17 loci. M. rufiventris genetic variation was found to be low, typical of an endangered species. The proportion of polymorphic loci was 5.88% in both ecosystems. Only Est-4 was polymorphic in colonies from the Forest and Mdh-1 in colonies from the Cerrado. The expected heterozygosity ranged from 0.0068 in the Cerrado to 0.0078 in the Forest. Despite this, enzyme electrophoretic analyses provided a good idea of the diversity between samples from Cerrado and Forest which reinforce the existence of two different "forms" of M. rufiventris in MG, one present in the Cerrado and the other in Forest. This information is of great importance for the conservation of M. rufiventris in MG. PMID:15859519

The SuBliMinaL Toolbox: automating steps in the reconstruction of metabolic networks.  

PubMed

The generation and use of metabolic network reconstructions has increased over recent years. The development of such reconstructions has typically involved a time-consuming, manual process. Recent work has shown that steps undertaken in reconstructing such metabolic networks are amenable to automation. The SuBliMinaL Toolbox (http://www.mcisb.org/subliminal/) facilitates the reconstruction process by providing a number of independent modules to perform common tasks, such as generating draft reconstructions, determining metabolite protonation state, mass and charge balancing reactions, suggesting intracellular compartmentalisation, adding transport reactions and a biomass function, and formatting the reconstruction to be used in third-party analysis packages. The individual modules manipulate reconstructions encoded in Systems Biology Markup Language (SBML), and can be chained to generate a reconstruction pipeline, or used individually during a manual curation process. This work describes the individual modules themselves, and a study in which the modules were used to develop a metabolic reconstruction of Saccharomyces cerevisiae from the existing data resources KEGG and MetaCyc. The automatically generated reconstruction is analysed for blocked reactions, and suggestions for future improvements to the toolbox are discussed. PMID:22095399

Nematophagous fungi in fresh feces of cattle in the Mata region of Minas Gerais state, Brazil.  

PubMed

The capacity to survive gut passage is one of the desirable characteristics for nematophagous fungi to be considered potential biological control agents of gastrointestinal nematodes of livestock. From April 1995 to April 1996, a pool of 10 cow fecal samples and 10 individual samples of feces from heifers, which were raised under partial (cows) or total (heifers) confinement in the Mata Region of Minas Gerais State, Brazil, were examined monthly for the presence of nematophagous fungi. A total of 10 isolates was found in the survey. Eight isolates were recovered from the pooled samples of cow feces and two from the individual samples of heifers. Fungi were present in the cow feces during the dry months of August (two isolates of Arthrobotrys oligospora and one Monacrosporium eudermatum) and September (one isolate of Harposporium lilliputanum and one of M. gephyropagum). Fungi were also recovered at the beginning and middle of the rainy season: one isolate of A. musiformis in October, and one isolate of M. gampsosporum and one unidentified fungus which produced septate hyphae and adhesive buds in December. In the individual samples collected from heifers, fungi were present only in the months of September (end of dry season) and March (end of rainy season). One isolate each of H. lilliputanum and A. oligospora were found, respectively. Additional studies to further characterize these isolates should be encouraged. PMID:10348101

Differences in coprophilous beetle communities structure in Sierra de Minas (Uruguay): a mosaic landscape.  

PubMed

Coprophilous beetles represent an abundant and rich group with critical importance in the functioning of terrestrial ecosystems. Most coprophagous beetles have a stenotopic distribution in relation to vegetation types. Because of this, they are usually very sensitive to environmental changes and are considered well suited as bioindicator organisms. The aim of this study was to analyze variations in coprophilous beetle assemblages in natural and anthropogenic habitats. Coprophilous beetle communities were sampled monthly for 1 year using pitfall traps baited with cow dung, in native xeric upland forests, 15-years-old plantations of Pinus elliottii and pastures in Sierra de Minas, Lavalleja, Uruguay. A total of 7,436 beetles were caught and identified to species or morphospecies level. The most abundant families were Aphodiidae, Scarabaeidae, and Staphylinidae. Differences in species richness, abundance, Shannon index, evenness, and dominance were detected between habitats. Abundances of most frequent families were significantly higher in both kinds of forests. Species richness and diversity of Aphodiidae and Staphylinidae were higher in forests, while Scarabaeidae showed the highest richness and diversity in pine plantations. Species composition significantly differed between habitats. Uroxys terminalis Waterhouse and Ataenius perforatus Harold typified the assemblages in native forests and pine plantations and also discriminated both communities because of their differential pattern of abundance between habitats. Typifying species in pastures were Onthophagus hirculus, Ateuchus robustus (Harold), and Ataenius platensis Blanchard. Habitat type had a strong effect on the coprophilous beetle community structure and composition. PMID:23950086

Serological survey of hantavirus in rodents in Uberlândia, Minas Gerais, Brazil.  

PubMed

We conducted a serological survey to determine the presence of hantavirus infection in rodents in Uberlândia, Minas Gerais as well as to identify and characterize associated factors. Rodents were captured using Sherman live-capture traps set in rural and peri-urban environments. A total of 611 rodents were captured. There was a higher trap success in peri-urban areas (26.3%) and a higher prevalence of antibodies among rodents captured in rural areas (2.9%). Necromys lasiurus was the most common species (42.2%) and the more frequently infected (4.6%). One Calomys tener (1/141; 0.7%) and one Calomys sp. (1/14; 7.1%) were also positive for the hantavirus infection. In N. lasiurus, antibody prevalence correlated with population density (p < 0.01), age class (p = 0.003) and presence of scars (p = 0.02). The data confirm that horizontal transmission is the main mechanism that maintains the virus in nature. The higher seropositivity in N. lasiurus is consistent with genetic studies that associate this species with an Araraquara virus reservoir; the seropositivity of C. tener and Calomys sp. may indicate the occurrence of spillover infection or the presence of other circulating hantaviruses.

Cerrado biome, the South American savannah, covers about 2 million km(2) and is very rich in endemic species but threatened by agriculture. In this report free-living tick species are presented, and their seasonal and relative distribution within the various phytophysiognomies in a small Cerrado reserve in Minas Gerais State, Brazil. Overall 2,694 free-living ticks were found during a 2 years sampling period with CO(2) traps and cloth dragging. Of these, 73.5% were Amblyomma cajennense and 0.6% Amblyomma dubitatum. All other ticks (25.9%) were retained as Amblyomma spp. Adults of A. cajennense peaked in spring, the nymphs in winter of both years. Amblyomma larval clusters were found in autumn and winter. Adult ticks (46.7%) and nymphs (39.5%) were most often found in woodlands, whereas most larval clusters were found in valley-side marshes (39%). Amblyomma cajennense, Anocentor nitens, Rhipicephalus (Boophilus) microplusand Rhipicephalus sanguineus ticks were found on domestic animals from neighboring properties. Search for Rickettsia in the hemolymph of 497 A. cajennense and one A. dubitatum ticks yielded negative results. Results confirmed earlier reports on the overwhelming prevalence of A. cajennense ticks in the Cerrado biome of Brazil and added information to habitat preferences of this tick species, a major vector in Brazil of the Rocky Mountain spotted fever.

Genotyping of Cryptococcus neoformans isolated from captive birds in Uberaba, Minas Gerais, Brazil.  

PubMed

To evaluate Cryptococcus spp. molecular types isolated from captive birds' droppings, an epidemiological survey was carried out in Uberaba, Minas Gerais, Brazil, from December 2006 to September 2008. A total of 253 samples of bird excreta (120 fresh and 133 dry) were collected from pet shop cages and houses in different neighbourhoods. Cryptococcus neoformans was isolated in 19 (14.28%) dry samples and one fresh sample (0.84%). Cryptococcus laurentii was recovered from seven (5.26%) dry samples, but not in the fresh samples. The canavanine-glycine-bromothymol blue test was positive in all but one of the C. laurentii isolates. Cryptococcus neoformans molecular typing was performed using URA5-RFLP and the mating type locus using mating type specific PCR. Nineteen (95.0%) presented genotype VNI and one VNII (5.0%). In addition, all isolates presented mating type ?. Thus, the genotype of the environmental C. neoformans isolates observed in this study is in accordance with others already reported around the world and adds information about its distribution in Brazil. Cryptococcus laurentii strains were typed using URA5-RFLP and M13 fingerprinting, which showed similar profiles among them. Thus, despite the low number of C. laurentii isolates analysed, their molecular profile is different from another already reported. PMID:20492533

PubMed

The city of Itabira, Minas Gerais State, Brazil, is located in the Espinhaço Mountain Range, an area that features large-scale mechanized iron ore pit mines. The current study evaluates the acute effects of inhalable particulate matter (PM10) in terms of emergency room visits due to respiratory and cardiovascular diseases in Itabira. Generalized additive Poisson regression models were adopted, controlling for temperature, humidity, and both short and long-term seasonality. Increases of 10mg/m(3) in PM10 were associated with increases in respiratory emergency room visits of 4% (95%CI: 2.2-5.8), at lags 0 and 1 for children and adolescents younger than 13 years of age, and of 12% (95%CI: 8.5-15.5) on the three subsequent days for adolescents (13 to 19 years of age). For cardiovascular diseases, the effect was acute (4%; 95%CI: 0.8-8.5) and mainly for the 45 to 64 age group. These results show that PM10 generated by open pit mining can lead to health problems in the exposed population. PMID:18038038

[Prescriptions for anorectic psychotropic drugs in the municipality of Juiz de Fora, Minas Gerais, Brazil].  

PubMed

Obesity is a serious public health issue of epidemic proportions. Although drug therapy is one of the therapeutic approaches, it should be preceded by a change in eating habits along with regular exercise. This study assessed prescription of such drugs in 2009, in Juiz de Fora, Minas Gerais, Brazil. Data were collected from consumption bulletins sent monthly to the municipal sanitary surveillance agency (VISA), and from the Brazilian National Management System of Controlled Products. Of the 7,759 notifications assessed, 93.3% were dispensed by prescription pharmacies and 6.7% by drugstores. Of that total, 55.4% were for amphepramone, 33.1% for femproporex, and 11.5% for mazindol. The three drugs had a larger consumption rate in the municipality (daily defined dose/1,000 inhabitants/day) than in the country as a whole, during the period under study. The professional with the highest prescription rate was responsible for 3,535 prescriptions. All of these were dispensed by prescription pharmacies, a single outlet being responsible for 99.5% of these prescriptions. This scenario shows that anorectic psychotropic drug prescription is a relevant public health issue and the criteria for monitoring the prescription and consumption of these drugs should be re-evaluated.

Occurrence of Listeria spp. in critical control points and the environment of Minas Frescal cheese processing.  

PubMed

Critical control points (CCPs) associated with Minas Frescal cheese (a Brazilian soft white cheese, eaten fresh) processing in two dairy factories were determined using flow diagrams and microbiological tests for detection of Listeria monocytogenes and other species of Listeria. A total of 218 samples were collected along the production line and environment. The CCPs identified were reception of raw milk, pasteurization, coagulation and storage. Thirteen samples were positive for Listeria; 9 samples were Listeria innocua, 2 were Listeria grayi and 2 were L. monocytogenes. In factory A, Listeria was found in 50% of raw milk samples, 33.3% of curd samples, 16.7% of pasteurized milk samples, 16.7% of cheese samples and 25% of rubber pipes used to transport the whey. The microorganism was not obtained from environmental samples in this plant. In factory B, Listeria was found in one sample of raw milk (16.7%) and in three samples of environment (17.6%) and L. monocytogenes was obtained from raw milk (16.7%) and the floor of the cheese refrigeration room (14.3%). Two serotypes, 4b and 1/2a, were observed among the strains of L. monocytogenes isolated, both which are frequently involved in outbreaks of food-borne listeriosis and sporadic cases of the disease all over the world.

Characterization of beryl (aquamarine variety) from pegmatites of Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

Eight samples of the beryl variety aquamarine were selected from four pegmatites in the Governador Valadares and Araçuaí regions in northeastern Minas Gerais State, Brazil. These samples were fully characterized by chemical analysis, infrared and UV-visible spectroscopy, thermal analyses, and high-temperature X-ray diffraction (from room temperature up to 800 °C). Several physical and chemical properties of beryl were found to depend on the amount of water and ions residing in the structural channels. The thermal expansion coefficients from room temperature to about 800 °C are temperature-independent, with ?a ? -3.2 × 10-6 ° C-1 and ?c ? -8.7 × 10-6 ° C-1. The contraction of both a and c unit-cell parameters with increasing temperature and the shift of the infrared band centered at about 1200 cm-1 were tentatively ascribed to interactions between channel water and the silicate rings.The color of beryl seems to be dictated by the relative proportions of Fe3+ in the octahedralsites and of fe2+ in the channels. Thus, deep-blue samples have little Fe3+, whereas greener samples have more Fe3+ or less channel Fe2+.

A geoprocessing approach for studying and controlling schistosomiasis in the state of Minas Gerais, Brazil.  

PubMed

Geographical information systems (GIS) are tools that have been recently tested for improving our understanding of the spatial distribution of disease. The objective of this paper was to further develop the GIS technology to model and control schistosomiasis using environmental, social, biological and remote-sensing variables. A final regression model (R(2) = 0.39) was established, after a variable selection phase, with a set of spatial variables including the presence or absence of Biomphalaria glabrata, winter enhanced vegetation index, summer minimum temperature and percentage of houses with water coming from a spring or well. A regional model was also developed by splitting the state of Minas Gerais (MG) into four regions and establishing a linear regression model for each of the four regions: 1 (R(2) = 0.97), 2 (R(2) = 0.60), 3 (R(2) = 0.63) and 4 (R(2) = 0.76). Based on these models, a schistosomiasis risk map was built for MG. In this paper, geostatistics was also used to make inferences about the presence of Biomphalaria spp. The result was a map of species and risk areas. The obtained risk map permits the association of uncertainties, which can be used to qualify the inferences and it can be thought of as an auxiliary tool for public health strategies. PMID:20721503

Modelling welded material for ultrasonic testing using MINA: Theory and applications  

NASA Astrophysics Data System (ADS)

Austenitic steel multi-pass welds exhibit a heterogeneous and anisotropic structure that causes difficulties in the ultrasonic testing. Increasing the material knowledge is a long term research field for LCND laboratory and EDF Les Renardières in France. A specific model has been developed: the MINA model (Modelling an Isotropy from Notebook of Arc welding). Welded material is described in 2D for flat position arc welding with shielded electrode (SMAW) at a functional scale for UT modeling. The grain growth is the result of three physical phenomena: epitaxial growth, influence of temperature gradient, and competition between the grains. The model uses phenomenological rules to combine these three phenomena. A limited number of parameters is used to make the modelling possible from the information written down in a notebook of arc welding. We present all these principles with 10 years' hindsight. To illustrate the model's use, we present conclusions obtained with two recent applications. In conclusion we give also insights on other research topics around this model : inverse problem using a F.E.M. code simulating the ultrasonic propagation, in position welding, 3D prospects, GTAW.

[Evaluating the implementation of Information System on Live Births in municipalities of Minas Gerais, Brazil].  

PubMed

This study evaluated the degree of implementation of the Information System on Live Births (SINASC) and its relationship to the organizational context in municipalities (counties) of Minas Gerais State, Brazil, in 2010. The sample included 132 municipalities that had healthcare facilities providing childbirth care and the decentralized SINASC. Data collection used a semi-structured questionnaire. Degree of implementation was defined by a scoring system with different weights for each indicator, according to the respective levels of importance assigned to them, using the following classification: adequate, inadequate, and critical. Data analysis used the median as the summary measure and the Pearson chi-square test for comparison of proportions. SINASC is not adequately implemented in the majority of the municipalities in the sample. Population size and quality of the municipal administration did not influence the degree of implementation. In terms of organization of information in the SINASC, the structure was evaluated as better than the process. Limitations included lack of qualified staff, unsatisfactory collection and completion of certificates of live birth, underutilization of data, and limited publication of the information.

Evidence of Borrelia in wild and domestic mammals from the state of Minas Gerais, Brazil.  

PubMed

The main of the study was to evaluate the presence of Borrelia burgdorferi infection in domestic and wild vertebrates and ectoparasites in endemic areas from the state of Minas Gerais, Brazil. A total of 445 serum samples were examined by ELISA, which used the Borrelia burgdorferi strain G39/40 U.S. source and 3,821 tick samples were tested by polymerase chain reaction (PCR). B. burgdorferi antibodies were found in 30 serum samples (6.74%); three in marsupials (7.69%), three in rodents (2.80%), nine in dogs (6.25%), and 15 in horses (9.68%). Nested-PCR performed in DNA samples obtained from collected ticks demonstrated negative results. Although attempts to amplify B. burgdorferi DNA from ticks had been not successful, the presence of seroreactive vertebrates suggests the possibility the Borrelia species circulating in these regions. Further research is required to provide information on the presence of Borrelia in Brazilian territory and its association with Baggio-Yoshinari syndrome. PMID:25054516

Speciation, distribution, and transport of mercury in contaminated soils from Descoberto, Minas Gerais, Brazil.  

PubMed

This work describes an investigation of mercury contamination in an abandoned gold mining site in the rural area of Descoberto, Minas Gerais, Brazil, whose inhabitants have reported "silver balls" present in the soil. Different granulometric fractions of soil samples and sedimented material from rainwater retention tanks in this area were analyzed for total mercury, organic matter, and mercury speciation by thermodesorption/atomic absorption spectrometry. The results showed mercury concentrations in the soils in the range of (0.0371-161) mg kg(-1), and the occurrence of Hg(0) oxidation. Some samples had concentrations as high as 90 mg kg(-1) with the majority as Hg(2+), which is important information in order to understand the biogeochemical behavior of mercury in contaminated sites and to apply the appropriate remediation technology. The retention boxes and tank samples showed that fine particles with high mercury content (3.3-90) mg kg(-1) are leached from the contaminated area, which reveals the need for efficient control of this material to prevent the contamination of stream waters. This study is an example that may be useful for other contaminated sites. PMID:19436865

A prevalence survey using the TF-Test technique to identify intestinal parasites was conducted in the Maxakali indigenous villages in Minas Gerais State, Brazil. Stool samples were collected on three alternating days, in separate tubes, containing 10% formalin, and unified in a laboratory by double filtering centrifugation. Samples of sediment aliquot were prepared in triplicate and examined by microscope (10x and 40x) for eggs, cysts, and larvae. Prevalence of parasites (89.5%) and polyparasitism (46%) were similar by sex and age, but varied by village. Prevalent species were: Entamoeba histolytica/Entamoeba dispar (48.9%), Giardia duodenalis (32%), Entamoeba coli (40.8%), Endolimax nana (10.3%), hookworms (37.9%), Schistosoma mansoni (23.7%), Hymenolepis nana (18.6%), Strongyloides stercoralis (5.4%), Ascaris lumbricoides (4.9%), and Trichuris trichiura (0.5%). The Maxakali population lives in socially vulnerable conditions, and government agencies need to introduce measures to improve sanitation infrastructure and health education. PMID:23568298

A structural analysis of the Minas da Panasqueira vein network and related fracture generations  

NASA Astrophysics Data System (ADS)

The Minas da Panasqueira is a world-class W-Cu-Sn vein-type deposit, situated within the Central Iberian Zone of the Palaeozoic Iberian Massif (Portugal). The deposit consists of a network of subhorizontal, sill-like massive quartz veins situated above the southwestern extremity of a greisen cupola, within regionally metamorphosed, isoclinally folded, lower-greenschist slates and greywackes. The greisen cupola is part of a larger intrusive complex, emplaced during the late- to post-tectonic stage of the Variscan orogeny. The late-Variscan granitoid(s) underlying the Panasqueira deposit is considered to have served as a major metal source. The structure of the network of subhorizontal extension veins, consists of numerous planar vein lobes that are separated by host-rock bridges and merge at branch-points. A structural analysis demonstrates that not only within the Panasqueira mine, but also on a more regional scale, one or more generations of flat-lying fractures are present. The veins clearly exploited these pre-existing discontinuities, as confirmed by (1) the vein geometry being directly influenced by variations in the orientation of the initial fracture sets and (2) the geometry of the rock bridges and overlapping vein morphologies, consistently showing straight-line propagating crack tips. If veining is governed by a preferential, strongly developed anisotropy in the host rock, the hypothesis of vein lobes and rock bridges forming during propagation of the parent crack by tip-line bifurcation and confinement processes (Foxford et al., 2000) does not seem plausible. Instead, we propose that the rock bridges formed from several, initially separate and small veinlets that eventually overlapped in an en echelon arrangement during progressive propagation and inflation. Bending of the rock bridges and incipient vein rotation indicate that veining occurred near the brittle-ductile transition. Using a quantitative analysis of bridge orientations, vein aspect ratios and tip lines, we try to sort out if a dominant ?2 propagation direction, typical for hydrofractures, exists within the vein network. By doing so, we can evaluate whether the subhorizontal vein network formed under a compressive stress regime, or was mainly dictated by the strength anisotropy of the rocks under near-isotropic stress conditions of ?hmax ? ?hmin. The regional dominance of subhorizontal aplites, pegmatites and hydrothermal veins, exploiting subhorizontal fracture networks, occurs over a wide area of more than 100 km2 along the Serra de Estrela granitic massif (Derré et al., 1986). This orientation contrasts with the more common vertical attitude of granite-related hydrothermal veins, observed throughout the Iberian massif. A detailed orientation analysis of the fracture sets should allow to explore the possible causes of this particular late orogenic, flat-lying fracture network related to the granitic intrusion.

Diversity of phlebotomine sand flies (Diptera: Psychodidae) in Ibitipoca State Park, Minas Gerais, Brazil.  

PubMed

Leishmaniasis is a complex of zoonotic diseases that are endemic to many Brazilian states. They are transmitted to the vertebrates by the bite of the hematophagous female sand fly (Diptera: Psychodidae) vectors. Despite the increasing occurrence of visceral and cutaneous leishmaniasis cases in large urban centers, their transmission continues to occur primarily in a wild environment and may be associated with professional activities, ecotourism activities, or both. This study investigates the ecological parameters of the sand flies present in Ibitipoca State Park, Minas Gerais, Brazil. During 2009, systematic collections of sand flies were made monthly using HP light traps installed at five sites, including three natural settings (a cave, riparian vegetation, and a rain forest), the tourist and researchers' accommodations, and a surrounding domestic livestock area. In total, 161 sand flies (seven species) were collected, the most abundant, particularly in the surrounding domestic livestock area, being Lutzomyia (Psychodopygus) lloydi (Antunes, 1937). Furthermore, a previously unidentified Lutzomyia (Sciopemyia) sp. was prevalent in the cave environment. There are no existing records of the occurrence of leishmaniasis in Ibitipoca State Park; however, the some species of the subgenus Psychodopygus are known vectors of Leishmania spp in Brazil. Hence, the presence of a species of this genus in areas surrounding the park may represent a risk to ecotourism and the local inhabitants. Our study shows the importance of regular monitoring of the various areas used by humans to determine the distribution and spread of sand fly vectors for preventive management to forestall potential risk to health and consequent effect on ecotourists.

Listeria monocytogenes occurrence was assessed in three slaughterhouses located in Minas Gerais state, Brazil, by analysis of 209 bovine carcasses. Four sponge samples were obtained from each carcass in different steps (A, from hide, before bleeding; B, after hide removal; C, after evisceration; and D, after end washing), resulting in a total of 836 samples. The samples were tested for the presence of L. monocytogenes according to the International Organization for Standardization 11290-1, and positive results were recorded in steps A (1 of 209) and D (1 of 209) from slaughterhouse 03. L. monocytogenes isolates (n = 5) were identified by multiplex PCR as belonging to serogroup IIc (representing serotypes 1/2c or 3c) and presented identical pulsed-field gel electrophoresis profiles; in addition, the isolates harbored the virulence genes inlA, inlB, inlC, inlJ, plcA, hlyA, actA, and iap and were sensitive to ampicillin, vancomycin, gentamicin, erythromycin, tetracycline, rifampin, chloramphenicol, trimethoprim, and sulfamethoxazole. The obtained data indicated a low occurrence of L. monocytogenes on bovine hides and carcasses from slaughterhouses located in Minas Gerais state, Brazil, and the presence of distinct virulence makers and susceptibility to a variety of antimicrobials by the obtained isolates.

A saprobic index for biological assessment of river water quality in Brazil (Minas Gerais and Rio de Janeiro states).  

PubMed

Based upon several years of experience in investigations with macrozoobenthos in rivers in the states of Minas Gerais and Rio de Janeiro, a biological assessment system has been developed to indicate pollution levels caused by easily degradable organic substances from sewers. The biotic index presented here is aimed at determining water's saprobic levels and was, therefore, named the "Saprobic Index for Brazilian Rivers in Minas Gerais and Rio de Janeiro states" (ISMR). For this purpose, saprobic valences and weights have been established for 122 taxa of tropical macrozoobenthos. Investigations were carried out in little, medium sized and big rivers in mountains and plains. Through ISMR, a classification of water quality and the respective cartographic representation can be obtained. Data collection and treatment methods, as well as the limitations of the biotic index, are thoroughly described. ISMR can also be used as an element to establish complex multimetric indexes intended for an ecological integrity assessment, where it is essential to indicate organic pollution. PMID:19387856

Reconnaissance geologic study of the Vazante zinc district, Minas Gerais, Brazil  

USGS Publications Warehouse

The Vazante district, Minas Gerais, 130 km south of Paracatu, produces nearly all of Brazil's zinc metal. The district is situated on the western side of the Late Precambrian Bambul basin and along the eastern and leading edge of the north-trending Brazilian orogenic belt (ca. 600-500 m.y. old) that borders the western margin of the basin. Reconnaissance study indicates that bedding and low-angle thrust faulting, folding, and low-grade metamorphism dominated the structural development of the district. The structural trend within the district is northeasterly, and dips 20?-45 ? NW. Three sets of folds developed during the main period of eastward thrusting of older Precambrian rocks over the western margin of the Bambui basin. A fourth fold set is transverse to the regional trend. The rocks in the district are tentatively assigned to the Paraopeba Formation of the Bambui Group and are designated A through C in ascending order. Unit A is phyllite to phyllitic siltstone. Unit B consists of interbedded dolomitic limestone and marl-limestone. Irregularly distributed limestone ledges 20 to 100 m thick have the appearance of boudins. Their origin is attributed to a combination of rapid lateral facies changes and differential movement at different structural levels along bedding and low-angle thrust faults, with the formation of tear faults vertically limited by the thrust faults. Unit C consists of interbedded siltstone, dolomitic limestone, and sandstone. Phyllitic rocks along member interfaces in units B and C and at the base of unit C indicate differential penetrative deformation and bedding faulting. The contacts between units A, B, and C are interpreted to be low-angle or bedding faults, and their original stratigraphic positions with respect to each other is unknown. Zinc silicate minerals (hemimorphite and willemite) occur in a folded breccia zone in the lower part of unit B. The breccia zone is interpreted to be tectonic in origin, having formed along the step of a step-bedding-plane fault during the Brazilian orogeny. The zinc is probably syngenetic, and ore deposition in the breccia may have occurred during Brazilian time. Broad uplift and deep weathering of the region took place during late Mesozoic and Cenozoic time. Reserves may be as high as 3 million tons of zinc metal.

Shallow Seismic Reflection Study of Recently Active Fault Scarps, Mina Deflection, Western Nevada  

NASA Astrophysics Data System (ADS)

During the spring and summer of 2006 University of Kansas geophysics students and faculty acquired shallow, high resolution seismic reflection data over actively deforming alluvial fans developing across the Emmigrant Peak (in Fish Lake Valley) and Queen Valley Faults in western Nevada. These normal faults represent a portion of the transition from the right-lateral deformation associated with the Walker Lane/Eastern California Shear Zone to the normal and left-lateral faulting of the Mina Deflection. Data were gathered over areas of recent high resolution geological mapping and limited trenching by KU students. An extensive GPR data grid was also acquired. The GPR results are reported in Christie, et al., 2006. The seismic data gathered in the spring included both walkaway tests and a short CMP test line. These data indicated that a very near-surface P-wave to S-wave conversion was taking place and that very high quality S-wave reflections were probably dominating shot records to over one second in time. CMP lines acquired during the summer utilized a 144 channel networked Geode system, single 28 hz geophones, and a 30.06 downhole rifle source. Receiver spacing was 0.5 m, source spacing 1.0m and CMP bin spacings were 0.25m for all lines. Surveying was performed using an RTK system which was also used to develop a concurrent high resolution DEM. A dip line of over 400m and a strike line over 100m in length were shot across the active fan scarp in Fish Lake Valley. Data processing is still underway. However, preliminary interpretation of common-offset gathers and brute stacks indicates very complex faulting and detailed stratigraphic information to depths of over 125m. Depth of information was actually limited by the 1024ms recording time. Several west-dipping normal faults downstep towards the basin. East-dipping antithetic normal faulting is extensive. Several distinctive stratigraphic packages are bound by the faults and apparent unconformitites. A CMP dip line was also run across a large active scarp in Queen Valley near Boundary Peak. Due to slope steepness and extensive boulder armoring shot and receiver locations had to be skipped within several meters of the actual scarp location. Initial structural and stratigraphic interpretations are similar to those in the Fish Lake Valley location. Overall the data prove that the actively deforming fans can be imaged in detail sufficient to perform structural and possibly seismic stratigraphic analysis within the upper one hundred meters of the fans, if not deeper.

Gametogenesis and reproduction of the matrinxã Brycon orthotaenia (Günther, 1864) (Pisces: Characidae) in the São Francisco river, Minas Gerais, Brazil.  

PubMed

The gametogenesis and reproduction of the matrinxã, Brycon orthotaenia in the São Francisco river, Pirapora Region, Minas Gerais, were studied from December, 1998 to November, 1999. The matrinxã B. orthotaenia is an endemic species in the São Francisco river basin in Brazil and important for commercial fishing. The size of the 1st gonadal maturation, indicated by the total length of the smallest spent males and spawned female, was 32.0 and 40.5 cm respectively. Reproduction occurred from October to January, when high frequencies of females and males at an advanced ripening/mature stage and spawned females were found. The short spawning period and histological characteristics of spawned ovaries containing only oocytes in stages of initial development, along with post-ovulatory and atresic follicles, indicated that Brycon orthotaenia presents total spawning.

[Seroepidemiological survey for infections by fungi causing systemic mycoses in the Xacriabá Indian Reserve, Minas Gerais State, Brazil].  

PubMed

Xacriabá Indian Reserve is situated in the north of Minas Gerais State, Brazil, near the municipality of Manga and São Francisco River. The Indian population is miscegenated with caucasian and negroid people and have farming activities. Blood samples were collected from 180 inhabitants of the reserve (85 men and 95 women), 15 to 84 years old. Serum antibodies against antigens of Paracoccidioides brasiliensis, Histoplasma capsulatum, Cryptococcus neoformans, and Candida albicans were tested for by counterimmunoelectrophoresis method. Seropositivity was verified in 5%, 3.9%, 4.2%, and 6.7%, respectively of the 180 samples. Those seropositive for antigens of P. brasiliensis and H. capsulatum were predominantly women and had lower age and more elevated mean titers of antibodies than individuals whose sera reacted with antigens of C. neoformans and C. albicans. The results suggest the occurrence of paracoccidioidomycosis-infection and histoplasmosis-infection in the Xacriabá Indian Reserve, particularly in the first decades of life of the inhabitants.

[Surveillance of phytotherapeutic drugs in the state of Minas Gerais. Quality assessment of commercial samples of chamomile].  

PubMed

Marketing of medicinal plants and phytotherapeutic products is spreading all over the world. In order to assess the commercialization of medicinal plants and phytotherapeutic products in the State of Minas Gerais, we identified and tested for the presence of adulterants and active ingredients in 27 samples of chamomile. All the samples consisted of Matricaria recutita flowers, but they were badly fragmented, a result of excessive handling and poor preservation. All samples contained contaminants, and insects were observed in 63% of the samples sold in drugstores. Only 50% of the samples in each group had the essential oils needed to produce antiinflammatory activity. Flavonoids and other phenolic constituents with a spasmolytic effect were detected in only 20% of the samples from each group. Results with chamomile indicated the poor quality with which medicinal plants and phytotherapeutic products are marketed and confirm the need for surveillance of such products in Brazil.

A thirty years follow-up study on Schistosomiasis mansoni in a community of Minas Gerais, Brazil.  

PubMed

During thirty years - 1973-2003 - a group of individuals infected by Schistosoma mansoni in Capitão Andrade, Rio Doce Valley, Minas Gerais, Brazil, was evaluated by the same authors, being one of the longest follow-up studies on schistosomiasisis mansoni in an endemic area. The diagnosis of S. mansoni was based on parasitological stool tests. In the clinical classification, three groups were considered: type I - schistosomiasis-infection, type II - hepatointestinal form, and type III- hepatosplenic form. The prevalence of infection were 60.8% in 1973, 36.2% in 1984, 27.3% in 1994, and 19.4% in 2003, while the index of hepatosplenomegaly were respectively 5.8%, 2.8%, 2.3% and 1.3%. The maintenance of high prevalence and severity of clinical forms are probably related to reinfection. PMID:18209943

[Positive breathalyzer test: factors associated with drinking and driving in the city of Belo Horizonte, Minas Gerais State, Brazil].  

PubMed

Few researches in Brazil have focused on factors associated with drinking and driving. The current study presents data on the prevalence and characteristics of individuals that drive under the influence of alcohol (DUI) in nine regions of the city of Belo Horizonte, Minas Gerais State, Brazil. A total of 1,656 drivers were interviewed, of whom 1,254 (76%) agreed to answer a structured questionnaire and submit to the breathalyzer test. The breathalyzer test was positive in 15% of these drivers. The logistic regression model predicted 1.5 times higher odds of a positive breathalyzer test in drivers over 31 years of age and 4.5 times higher in individuals that reported at least weekly alcohol consumption. In addition, drivers in the Barreiro region showed two-fold odds of a positive breathalyzer test. Focused studies with sobriety checkpoints can monitor DUI behavior, drivers' characteristics, and traffic risks, meanwhile orienting public policies to prevent drinking and driving. PMID:23370024

[Iron ore, economic geology and networks of experts between Wisconsin and the state of Minas Gerais, 1881-1914].  

PubMed

This article deals with the "discovery" of Brazilian iron ore from two perspectives. The first examines the increasing emphasis of the geosciences and their practical application and global reach since the second half of the nineteenth century. While in Brazil economic geology was integrated step by step into state institutions, at the global level it experienced its moment of triumph with the 11th International Geological Congress in 1910. The second deals with a specific social network with a decisive role in the race for Brazilian iron ore: with transnational experts juggling between the logic of the market and that of the academy. The article reveals the importance of local negotiations in the incorporation of the subsoil of Minas Gerais into the global space of mining. PMID:24554136

Identification of virulence factors by multiplex PCR in Escherichia coli isolated from calves in Minas Gerais, Brazil.  

PubMed

In this study, multiplex PCR was employed to investigate the virulence factors of Escherichia coli strains isolated from 60-day-old calves. Faecal samples were collected from 54 calves at 12 dairy farms in the state of Minas Gerais, Brazil. A total of 156 isolates were obtained after culture and microbiological isolation and were tested by multiplex PCR for the presence of genes encoding toxins (Stx1, Stx2 and STa) and adherence factors (intimin, F41 and F5). Seventy of 156 isolates were positive for at least one virulence factor: ten (14.3 %) from diarrhoeic animals and 60 (85.7 %) from healthy calves. The virulence markers identified were: Stx1 (82.8 %), eae (24.3 %), F41 (11.4 %), F5 (10 %), STa (4.28 %) and Stx2 (4 %). In diarrhoeic animals, Stx1 (70 %) and F41 (30 %) were identified, while Stx1 (83.3 %), eae (28.3 %), F41 (8.3 %), F5 (11.6 %), STa (5 %) and Stx2 (1.6 %) were detected in isolates from healthy calves. Mixed infections with pathotypes Shiga toxin-producing E. coli (STEC)/enteropathogenic E. coli, STEC/enterohaemorrhagic E. coli and STEC/other (eae/F5, Stx1/STa) were detected in five healthy calves. Pathogenic E. coli were identified in 59.26 % of all calves and on 75 % of the dairy farms studied, not only in diarrhoeic (five of six) but also in healthy calves (27 of 48), which demonstrates the importance of this agent in the aetiology of diarrhoea in calves in the state of Minas Gerais.

How Stakeholder Engagement is Evolving at the Caldas Uranium Mining Site in Minas Gerais, Brazil - 13223  

SciTech Connect

The Caldas site is located in the Federal State of Minas Gerais in Brazil about 25 km from the city of Pocos de Caldas. While the city itself has 150,000 inhabitants there is a total population of around 0.5 million people living in an area that could potentially be influenced by the site. Uranium ore was mined and milled here between the years of 1982 and 1995, with ore extraction taking place from an open pit. Of the material removed, aside from that extracted for uranium, some was used on-site for road construction and building embankments while the remainder was disposed of onto two major rock piles. There are a number of potential historical and current environmental impacts to groundwater as a consequence of discharges into streams which then flow off site. The site is now undergoing a phase of decommissioning which includes the formulation and substantiation of a site remediation strategy. As part of a wider International Atomic Energy Agency (IAEA) Technical Cooperation Project aimed at providing practical guidance for implementing a decommissioning and remediation plan at the site, WSP E and E were invited to lead a mission in order to provide advice on the importance and merits of stakeholder engagement and how to ultimately build an engagement program. In November 2011, WSP E and E met with personnel from the site operators, the Brazilian regulatory bodies and representatives from the local stakeholder community and explained the principles of stakeholder engagement and how the process had internationally evolved principally from a decide-announce-defend approach to a more formal two way mechanism of engagement. Historically there had been insufficient liaison between the site operator, the nuclear regulator and the environmental regulator. All parties had recognized that greater interaction was necessary. There had also been very little engagement with local stakeholders about the various activities on the site and the potential implications of these activities on human health and the environment. The main concerns of the local stakeholders were in relation to potential environmental impacts on groundwater and surface water as well as their lack of knowledge about the site's activities and how it might evolve over time. There was a feeling that the site brought no real benefit to the local community as local labor was rarely utilized when work was being undertaken. WSP E and E were asked many questions about stakeholder engagement processes and had to address a number of concerns relating to being able to construct and control an engagement program. Advice was provided on how to construct a phased program in a manner that would allow the site operator to demonstrate increased transparency and allow as wide a range of stakeholders as possible the opportunity to become engaged. We provided an important message in that engagement often had to be culture and project specific and that what might work in one country could not necessarily purely be transposed to another. Since the WSP E and E mission there has been evidence of a number of positive steps in many of the areas of stakeholder engagement related to the Caldas site. The nuclear and environmental regulators work in a more open and transparent manner and continue to undertake joint inspections of the Caldas site. They have agreed to develop a written agreement that will enable them to jointly assess and discuss the issues on the site. Both regulatory bodies had previously accompanied the site operator on a visit to the Wismut uranium mining area in Germany and as well as providing useful learning had also allowed the regulators to discuss some common issues, thus bringing them closer together. A local stakeholder group under the auspices of the Water Commission had previously been set up but now they are starting to have more regular meetings with the site operator and nuclear regulator. They are now additionally considering the formation of a site specific advisory board (based on similar lines to those at US legacy sites) in order to gain some further tec

Projeto Vida no Vale: universal access to water and sanitation in the North East of Minas Gerais (Brazil)  

NASA Astrophysics Data System (ADS)

In the rural areas of the developing countries, the access to water supply and sanitation services is still largely inadequate. Poor governance of the water sector is frequently singled out as a cause and reforms are required. Studies analyzing the great diversity of restructuring efforts currently being undertaken in the water sector have not succeeded in determining the most appropriate institutional and economic framework for such reforms. Moreover they underline the lack of documentation on actual projects and call for concrete models and tools for improving water and sanitation services (WSS) and for adapting water utility practice to real conditions. In this context, the Vida no Vale (Life in the Valley) project is aimed at bringing universal access to WSS for all inhabitants of both urban and rural areas, in the north-eastern area of the Brazilian State of Minas Gerais. The project takes sustainable development as its guiding principle, and relies on the joint implementation of an innovative technical design, a governance model involving public participation and subsidiarity, and an economic structure combining financial viability and social equity. Designed at a consistent geographical and hydrological scale, it includes the creation of a regional subsidiary of the existing state water company as a keystone element. The institutional organisation also relies on the creation of a public board consisting of the 92 municipalities of the project region and of the State of Minas Gerais. This board will be in charge of the system's governance. The paper will present the first step of the project (2006), consisting of a feasibility study and the implementation of 9 pilot sub-projects. During the feasibility study, the supply, demand and capacity to pay for water services were defined, existing infrastructure appraised, the necessary amount of investment assessed and an innovative operational model and a sustainable management system, including civil society participation, defined. The main features of the Vida no Vale project have been tested in 9 pilot sub-projects, and implemented in municipalities chosen for their low Human Development Index and for the lack of WSS, in both urban and rural areas. A second phase corresponding to the project's final implementation will run from 2007 to 2011. The ongoing successful accomplishment of the Vida no Vale project would make it an exemplary and replicable model for other poor regions.

Evaluation of a program to overcome vitamin A and iron deficiencies in areas of poverty in Minas Gerais, Brazil.  

PubMed

Randon samples of children from both sexes from Belo Horizonte, the capital City, and from Turmalina, Jequitinhonha Valley, Minas Gerais, Brazil, were submitted to nutritional evaluation before and after the intervention "Program to Overcome Vitamin A and Iron Deficiencies in Areas of Poverty in Minas Gerais, Brazil". After the first examination, all the children received, with an interval of 180 days, a single oral dose of vitamin A, oral iron sulfate during 50 days, and 200 mg of Mebendazol/day for three days. Thirty days after ending administration of the third dose of medicine, the children were subjected to a new evaluation. In Belo Horizonte, the first evaluation revealed a high prevalence of deficient and low values of vitamin A in preschool children (21.5%) and school children (21.7%). A small prevalence of low hematocrit values was also observed in both groups. Deficient and low values of hemoglobin were found as well in 21.5% of preschool children and in 17.5% of school children. The second evaluation, practiced 30 days after the third dose of medicine, showed a small incidence of low vitamin A values (4.3% in preschool children and 2.9% in school children) and low hemoglobin values (6.5% in preschool children and 2.9% in school children). No deficient values of hemoglobin and vitamin A were observed. Concerning the hematocrit value, only one school child presented a low value at the second evaluation. On the other hand, in Jequitinhonha Valley, five cases of Bitot spot with conjunctival xerosis, two cases of corneal xerosis, and one case of keratomalacia were detected at the first examination. Thirty days after ending the third dose of medicine, only one corneal scar was observed. Only a small number of children with deficient and low levels of vitamin A and hemoglobin was found in the final evaluation (less than 8%), while this number was high at the first evaluation (above 38 and 12%, respectively). These results show the efficiency of the intervention Program in relation to hypovitaminosis A and iron anemia prevention. The Program is now being implemented by the Brazilian Ministry of Health.

Regional sulfate-hematite-sulfide zoning in the auriferous Mariana anticline, Quadrilátero Ferrífero of Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

The distribution of mineral deposits, characterised as barite deposits, hematite-rich auriferous deposits and auriferous tourmaline-sulfide deposits, displays a regional sulfate-hematite-sulfide zoning along the thrust-delineated limbs of the Mariana anticline, in the south-eastern part of the Quadrilátero Ferrífero of Minas Gerais, Brazil. Cross-cut relationships of barite veins and sulfide lodes indicate that sulfidation occurred in a late-tectonic context, which is here attributed to the collapse of the ˜0.6-Ga Brasiliano thrust front. Reconnaissance S-isotopic data from barite and pyrite (Antônio Pereira barite deposit and its adjacent gold deposit, respectively), and arsenopyrite (Passagem de Mariana gold deposit), suggest a new interpretation for the hydrothermal fluid overprint in the Mariana anticline. The Antônio Pereira barite has ?33S values that are near zero, constraining the sulfate source to rocks younger than 2.45 Ga. The barite-?34S values are between +19.6 and +20.8 ‰. The Passagem arsenopyrite and tourmaline have Co/Ni ratios that define a positive linear trend with the Antônio Pereira pyrite. The latter has homogenous ?34S values, between +8.8 and +8.9 ‰, which are compatible with thermochemical reduction of aqueous sulfate with the S-isotopic composition of the Antônio Pereira barite.

The presented paper considered the pollen morphology of thirteen species belonging to seven genera of the Fabaceae family occurring in the Pau-de-Fruta Special Protection Area (SPA), Diamantina, state of Minas Gerais, Brazil. The pollen grains of six species of Chamaecrista [C. cathartica (Mart.) H.S. Irwin & Barneby, C. debilis Vogel, C. flexuosa (L.) Greene, C. hedysaroides (Vogel) H.S. Irwin & Barneby, C. glandulosa (L.) Greene, and C. papillata H.S. Irwin & Barneby] have a similar morphology, characterized by three long colporated apertures with a central constriction. The species share specific morphological features regarding pollen size, endoaperture type (circular, lalongate or lolongate) and SEM ornamentation patterns of the exine (rugulate with perforations or perforate). Andira fraxinifolia Benth., Dalbergia miscolobium Benth, Galactia martii DC, Periandra mediterranea (Vell.) Taub., Senna rugosa (G.Don) H.S. Irwin & Barneby and Zornia diphylla (L.) Pers showed different pollen types in small to large size; oblate spheroidal to prolate form; colpus or colporus apertures; circular, lalongate or lolongate endoapertures and distinctive SEM ornamentation patterns of the exine (perforate, microreticulate, reticulate or rugulate with perforations). Only Stryphnodendron adstringens (Mart.) Coville presents polyads. The pollen morphology variation of these species allowed the Fabaceae family to be characterized as eurypalynous in the SPA Pau-de-Fruta. PMID:24346795

PubMed

This study set out to describe the profile of the patients with voice complaints and/or alterations who were attended between July 2003 and December 2006 at the speech therapy outpatient unit of "Hospital das Clínicas da Universidade Federal de Minas Gerais." This was analyzed according to age, sex, profession, schooling, origin, treatment performed and factors that interfere in medical care evolution. This was a retrospective study based on the analysis of the recorded data of the individuals according to a specifically prepared Protocol. The results showed that the individuals included in this study were predominantly young women, referred by a specialist from Belo Horizonte, who do not work and also have incomplete elementary school education. Attendance of those patients was on an individual basis, and almost half of them were discharged by the speech therapist. The elderly patients, who have functional or psychogenic dysphonia and a neutral or wheezy type of voice, showed a close correlation with the discharge rate by speech therapist. The younger individuals with organo-functional dysphonia bore a statistical correlation with abandoning treatment. The individuals who eventually abandoned treatment did not bear any correlation with the crossed variables. PMID:21808900

Substance use and sexual risk among at-risk adolescents in Juiz de Fora, Minas Gerais State, Brazil.  

PubMed

We examined the difference in prevalence of substance use and sexual risk behaviors among at-risk youth participants in programs offered by community-based organizations in Juiz de Fora, Minas Gerais State, Brazil, by gender and organization type (governmental vs. non-governmental). 388 adolescents were recruited from 25 intervention-based organizations servicing at-risk youth between the ages of 12 and 17 in Juiz de Fora. Participants completed a 15-item survey assessing substance use and sexual risk behaviors, along with socio-demographic predictors of these behaviors. Males were more likely to report drug and alcohol use associated with homelessness and abandonment. Females were more likely to report sexual risk taking associated with neighborhood crime. Participants from non-governmental organizations were less likely to engage in all measured risk behaviors. The present analysis points to the need to understand how Brazil's Child and Adolescent Act is being applied and the implications this has for intervention and the promotion of positive health outcomes for young people.

Plagioscion squamosissimus (Sciaenidae) and Parachromis managuensis (Cichlidae): a threat to native fishes of the Doce River in Minas Gerais, Brazil.  

PubMed

The middle section of the lake basin of the Doce River in Minas Gerais State, Brazil is plagued by grave environmental problems, including the introduction of non-native fish, which reduces the biodiversity of this region. This study reports the presence of two newly-detected non-native species in the Doce River Basin. Sampling efforts included gill nets with mesh size of 3 to 12 mm (measured diagonally) and trawling nets, both of which were used in independent field campaigns in 2002 and 2011. The two new invasive Perciform fishes, Plagioscion squamosissimus (Heckel 1840) and Parachromis managuensis (Günther 1867) were collected in Caratinga and Rio Doce municipalities. These records and other reports on non-native fishes suggest favorable environmental conditions for the establishment of invasive species in this drainage. These invasive species have behavior and diet observed in other wide distribution exotic fish of Rio Doce Basin representing a threat to the 77 native fishes of this region, 37 of which are endangered.

[Congenital transient hypothyroidism: characteristics of children identified at Newborn Screening Program of the State of Minas Gerais, Brazil].  

PubMed

Early diagnosis and treatment of congenital hypothyroidism are the main goals of the neonatal screening programs. A retrospective analysis was carried out to assess the characteristics and etiologies of congenital transient hypothyroidism (CTH) in the Newborn Screening Program of the State of Minas Gerais, Brazil. To reach a diagnosis of CTH, altered screening and serum confirmatory T4 and TSH tests and normal serum free T4 and TSH at 4 and 8 weeks after the withdrawal of levothyroxine were used. We studied 21 children with CTH who represented 4.23% of the whole group with detected hypothyroidism and followed them up in the Screening Program. These patients received LT4 therapy for a variable period of one month to three years. Serum confirmatory TSH levels varied from 10.4 to 583.4 microUI/mL. Maternal antibodies, TRAB and anti-TPO, were associated to CTH in two children and iodine overload in one of them. We concluded that CTH is an important component in neonatal screening and hormonal treatment during the first months of the life is essential. The TSH initial levels are not relevant to determine whether the thyroid dysfunction is transient or permanent. PMID:16358080

The main species found were Dermatophagoides pteronyssinus, D. farinae, Euroglyphus maynei, Blomia tropicalis and Tyrophagus putrescentiae. In a minor incidence we found Lepidoglyphus destructor, Suidasia pontificiae, Chortoglyphus arcuatus, Cheyletus malaccensis, C. fortis, Ker bakeri, Cheletonella vespertilionis, C. caucasica and others. C. vespertilionis and C. caucasica were identified for the first time in the domiciliary ecosystem and in Brazil. The abundance rate and the infestation intensity were analyzed. There was a varied correlation between climatic conditions and positive domiciles and number of mites. The difference between the number of positive domiciles in the urban area and in the expanding urban area was significant and so was the difference between samples from the domiciles compared to those from the kitchens.

Evaluation of mosquito (Diptera: Culicidae) species richness using two sampling methods in the hydroelectric reservoir of Simplício, Minas Gerais, Brazil.  

PubMed

We compared two types of light traps used for monitoring mosquito abundance in the hydroelectric reservoir of Simplício, Além Paraíba - Minas Gerais. Mosquitoes were captured bimonthly using automatic CDC and Shannon traps before the filling of the hydroelectric plant reservoir from December 2008 to December 2009. In total, 1474 specimens from 13 genera were captured. Among the captured specimens, several species known to be vectors of disease-causing agents for humans and/or animals were identified, including Anopheles aquasalis, Aedes albopictus, Coquillettidia venezuelensis, Haemagogus leucocelaenus, and Aedes scapularis. Sampling efficacy between the four capture sites was not found to be significantly different, irrespective of species captured or type of trap used. Poor correlation (r (x, y) = -0.0444) between the number of mosquito species and capture site was observed when not influenced by the type of trap used. Among the installation sites of the CDC and Shannon traps in the areas investigated, CDC traps fixed in livestock shelters obtained an overall higher abundance of species captured. PMID:22468830

Fructification phenology as an important tool in the recovery of iron mining areas in Minas Gerais, Brazil.  

PubMed

'Canga' is a name given to the ferruginous rocky fields that can be found in the 'Quadrilátero Ferrífero' of Minas Gerais, Brazil. The endemism and species richness make them areas of special biological importance, regarded as high-priority for conservation. Nevertheless, they are being threatened by intense mining activity. Aiming to understand more about this flora, this study was performed in order to determine the maturation or dispersal period of the fruits of four Canga species, Alibertia vaccinioides K.Schum. (Rubiaceae), Coccoloba acrostichoides Cham. (Polygonaceae), Miconia sellowiana Naudin (Melastomataceae), and one probable new species of Calyptranthes Sw. (Myrtaceae). Although fruit maturation or dispersal tended to occur at the end of the dry season, some asynchrony was observed in these species, with food sources being available during most of the year. This shows that these species have the potential to attract animals the whole year round, and planting them for the recovery of iron mining areas may increase the community's self-regeneration capacity, leading to a more successful restoration process.

Schistosoma mansoni infection in a rural area of the Jequitinhonha Valley, Minas Gerais, Brazil: analysis of exposure risk  

PubMed Central

This study examines the relative contribution of age-specific total IgE levels, eosinophils and water contact behavior to the prevalence and intensity (geometric mean egg counts) of Schistosoma mansoni infection in the poor rural population of Virgem das Graças in northern Minas Gerais State. In bivariate analysis, age was strongly correlated with both prevalence and intensity of infection, while eosinophil levels with prevalence only (p<0.0001); IgE levels and 5 demographic and socioeconomic variables were moderately correlated with prevalence (p<0.05), as were number of persons per room and TBM (total body minutes) with egg counts. In multivariate analysis, after controlling for demographic and socioeconomic factors, only total IgE levels were significantly correlated with both prevalence (p=0.248, 95% CI= 1.01–1.11) and intensity (p=0.0217, 95% CI=0.01–0.14) of infection and eosinophil levels with prevalence (p=0.0005, 95% CI=1.07–1.24). Although any causal relationship cannot be confirmed by a cross-sectional study, we demonstrated an associated decrease in prevalence and intensity of S. mansoni infection with increased IgE levels.

[Menarche, early pregnancy, and obesity in selected Brazilian women from a health care center in Belo Horizonte, Minas Gerais, Brazil].  

PubMed

The aim of this study was to investigate obstetric variables potentially associated with obesity among 486 Brazilian childbearing-age women aged 15-59 residing in the municipality of Belo Horizonte, Minas Gerais State. Body fat (BF) was measured through impedance analysis, and obesity was defined as BF > 30%. The association between obstetrics factors and obesity was evaluated through multivariate logistic regression. The following variables remained in the logistic regression after adjustments for total income, smoking, alcohol consumption, and physical activity: age at menarche < 12 years (OR = 3.02; 95% CI: 1.62-5.61), age > 30 and < 39 (OR = 1.72; 95% CI: 1.01-2.92), age > 40 years (OR = 3.32; 95% CI: 1.76-6.27), age at first childbirth (OR = 1.99; 95% CI: 1.07-3.68), and the following interaction: age group > 30 and < 39 and age at menarche (OR = 0.27; 95% CI: 0.09-0.83). It appears that obstetric factors affect obesity through a complex network of interrelations that involve the covariates studied above. It is important to support efficient programs to prevent obesity, as well as family planning programs emphasizing a reduction in the prevalence of teenage pregnancies. PMID:12886441

[Morbidity in Chagas' disease. IV. Longitudinal study of 10 years in Pains and Iguatama, Minas Gerais, Brazil].  

PubMed

An evolutive study of the "case-control" type was carried out in an endemic area of Chagas' disease in Minas Gerais State, Brazil, using two cross-section evaluations with an interval of ten years between them (1974-1984). Patients were paired for sex and age. In the first cross-section study 264 pairs one with a positive serology and the other with a negative serology for T. cruzi antibodies were included. In the second evaluation, ten years later, 235 patients among those with previous positive serology and 216 with negative serology were located, but only 110 pairs could be recomposed and reexamined (clinical examination, ECG and Rx of the heart and esophagus). The incidence of chagasic cardiopathy in the cases with positive serology but previously assymptomatic was 38.3% during the ten year period. On the other hand there was a deterioration in 24% of the patients with chagasic cardiopathy since the first examination. Considering all clinical forms of the disease in 34.5% of the patients the clinical situation deteriorated, in 57.3% there was no change and in 8.2% the situation improved. The general mortality in the period was 23% in the chagasic group and 10.6% in the control group, but the lethality by cardiopathy was 17% in chagasic group and only 23.3% in the control group. The mortality was twice as high in males than in females, mainly in the age group from 30 to 59 years. PMID:3937015

[The Impact of Prohibition on drinking and driving in Belo Horizonte in the State of Minas Gerais].  

PubMed

The scope of this paper is to present comparative data on drinking and driving behavior among drivers in Belo Horizonte in the State of Minas Gerais, in the period from 2005 to 2009, evaluating the impact of Law No. 11.705 (Prohibition), dated June 6, 2008. Data regarding prevalence of this behavior, collected at Sobriety Checkpoints (internationally used methodology) were analyzed using representative samples obtained from drivers on different public roads with intensive traffic in Belo Horizonte (2005-2009), thus permitting analysis of the impact of the new law. In 2008, the data showed a reduction of approximately 50% in the prevalence of individuals driving with any level of alcohol in the blood, when compared to 2007, after the change in legislation. This study showed that the impact caused by Law No.11.705 was marked in the sense of modifying the behavior under scrutiny. However, other control measures need to be added to the current legislation, in order to obtain a continuous reduction of drinking and driving behavior, thereby fostering a culture of sobriety on the road.

Composition and abundance of small mammal communities in forest fragments and vegetation corridors in Southern Minas Gerais, Brazil.  

PubMed

Habitat fragmentation leads to isolation and reduce habitat areas, in addition to a series of negative effects on natural populations, affecting richness, abundance and distribution of animal species. In such a context, habitat corridors serve as an alternative for connectivity in fragmented landscapes, minimizing the effects of structural isolation of different habitat areas. This study evaluated the richness, composition and abundance of small mammal communities in forest fragments and in the relevant vegetation corridors that connect these fragments, located in Southern Minas Gerais, Southeastern Brazil. Ten sites were sampled (five forest fragments and five vegetation corridors) using the capture-mark-recapture method, from April 2007-March 2008. A total sampling effort of 6 300 trapnights resulted in 656 captures of 249 individuals. Across the 10 sites sampled, 11 small mammal species were recorded. Multidimensional scaling (MDS) ordinations and ANOSIM based on the composition of small mammal communities within the corridor and fragment revealed a qualitative difference between the two environments. Regarding abundance, there was no significant difference between corridors and fragments. In comparing mean values of abundance per species in each environment, only Cerradomys subflavus showed a significant difference, being more abundant in the corridor environment. Results suggest that the presence of several small mammal species in the corridor environment, in relatively high abundances, could indicate corridors use as habitat, though they might also facilitate and/or allow the movement of individuals using different habitat patches (fragments).

Characterization of medium distillate cut (100-230 sup 0 C) oil from high-ash Mina do Leao Brazilian coal tar  

SciTech Connect

The authors report Brazilian coal tar oil characterized by combined spectroscopic and chromatographic methods. A coal tar cut (100-230{sup 0}C) obtained from a gasifier plant operating with Mina do Leao high-ash coal was fractionated into ABN (acid-base-neutral) groups. Infrared spectra and elemental analysis of each fraction has demonstrated the success of the fractionation step. GC/MS analysis of the total cut before the ABN fractionation revealed only hydrocarbons present in the sample. However, after the pre-fractionation step several nitrogen containing compounds of environmental concern were positively identified by GC/MS in the tar bases fraction.

Yeasts and hygienic-sanitary microbial indicators in water buffalo mozzarella produced and commercialized in Minas Gerais, Brazil  

PubMed Central

The aim of this work was to study the yeast populations and the main hygienic-sanitary microbial indicators in water buffalo mozzarella produced and commercialized in Minas Gerais, Brazil. Forty-two water buffalo mozzarella samples were purchased from retail outlets in Belo Horizonte. In addition, five samples of consecutive starter cultures, curd before acidification, acidified curd and mozzarella were collected at an industry in the city of Oliveira. Only three of the five water samples analyzed were suitable for consumption according to Brazilian sanitary standards. Four milk samples were highly contaminated with fecal coliforms, and did not meet the minimal hygienic-sanitary standards according to Brazilian regulations. Only one sample of buffalo muzzarela purchased from retail outlets exceeded the limit for coagulase-positive Staphylococcus. Eleven samples showed counts of thermotolerant coliforms higher than 5 × 103 CFU.g?1, but still lower than the maximum permitted by the Brazilian laws. Salmonella spp. and Listeria monocytogenes were not isolated. Debaryomyces hansenii, Candida lusitaniae and C. parapsilosis were the prevalent yeast species isolated from cheese. Among samples from the production stages, the acidified curd presented the highest numbers of yeasts, with C. catenulata being the most frequent species isolated. Some opportunistic yeast species such as C. guilliermondii, C. tropicalis, C. parapsilosis, C. lusitaniae, C. catenulata, C. rugosa and C. krusei occurred in the mozzarella cheese samples analyzed. The mozzarella cheese presented a low microbial load as compared to other cheese already studied, and the yeast biota included species typical of cheese and also opportunistic pathogens.

Insects breeding in pig carrion in two environments of a rural area of the state of minas gerais, Brazil.  

PubMed

The main objective of this study was to identify potential forensic indicators in the insect fauna associated with pig carrion and the pattern of insect succession during the decomposition process in two environments of a rural area in Uberlândia, State of Minas Gerais, Brazil. The study was conducted at two locations: in a pasture and in a fragment of a semi-deciduous forest (vegetation profile of the Cerrado biome) in two different seasons (rainy and dry) of 2010. The decomposition process was more rapid in the rainy season. More than 32,000 insects belonging to 17 species of 6 families of Diptera and 2 species of Coleoptera bred in the carcasses. The majority of Diptera bred in the first three stages of decomposition. However, Phoridae and Coleoptera bred mainly in the last two stages. The insects bred more abundantly in the pasture and in the humid season. The exceptions were the Fanniidae (Diptera), which bred more abundantly in the forest and the Dermestidae and Cleridae (Coleoptera), which did not demonstrate any preference in terms of environments and were more abundant in the dry season, respectively. Species such as Chrysomya albiceps (Wiedemann), Peckia (Patonella) intermutans (Walker), Necrobia rufipes (De Geer), and Dermestes maculatus (De Geer) may be potential indicators of post-mortem interval. Hemilucilia segmentaria (Fabricius) and Ophyra aenescens (Wiedemann) may be indicators of localization of the natural environment, while Musca domestica Linnaeus may be an indicator of the anthropic environment. The study thus presented many species of potential forensic indicators in rural areas of this region. PMID:23949758

Risky consumption habits and safety of fluid milk available in retail sales outlets in viçosa, minas gerais state, Brazil.  

PubMed

Abstract This study aimed to assess raw milk consumption habits in the urban population of Viçosa, Minas Gerais, Brazil, and the microbiological safety and quality of the fluid milk available in retail sales outlets in the same region. A simplified questionnaire regarding raw milk consumption was applied to the persons responsible for food acquisition in 411 residences. The regular consumption of raw milk was observed by 18.5% of the interviewers, and lack of knowledge of possible risks related to this food product. Microbiological safety and quality were assessed for raw (n=69), pasteurized (n=80), and ultra-high-temperature (UHT)-treated milk (n=80) by analyzing the counts of mesophilic aerobes, coliforms, and Escherichia coli, and detection of Listeria monocytogenes and Salmonella spp.; raw milk samples were also subjected to enumeration of coagulase-positive Staphylococcus. Concerning raw milk, 59.4% of the samples were considered as produced in inadequate hygienic conditions, 5.8% of the samples presented counts of coagulase-positive Staphylococcus lower than 100 colony-forming units (CFU)/mL, and no samples presented with positive results for L. monocytogenes or Salmonella spp. All pasteurized and UHT milk samples presented with low counts of mesophilic aerobes and coliforms, while L. monocytogenes and Salmonella spp. were absent. The data demonstrated that raw milk was consumed by the population studied. Despite the absence of potential hazards, raw milk was of poor hygienic quality, in contrast with the processed fluid milk available in retail sales outlets that was safe and of good hygienic quality, highlighting the suitability of pasteurized and UHT milk for human consumption.

Radioactive source materials in Los Estados Unidos de Venezuela  

USGS Publications Warehouse

This report summarizes the data available on radioactive source materials in Los Estados Unidos de Venezuela accumulated by geologists of the Direccions Tecnica de Geolgia and antecedent agencies prior to June 1951, and the writers from June to November 1951. The investigation comprised preliminary study, field examination, office studies, and the preparation of this report, in which the areas and localities examined are described in detail, the uranium potentialities of Venezuela are summarized, and recommendations are made. Preliminary study was made to select areas and rock types that were known or reported to be radioactive or that geologic experience suggests would be favorable host for uranium deposits, In the office, a study of gamma-ray well logs was started as one means of amassing general radiometric data and of rapidly scanning many of ye rocks in northern Venezuela; gamma-ray logs from about 140 representative wells were examined and their peaks of gamma intensity evaluated; in addition samples were analyzed radiometrically, and petrographically. Radiometic reconnaissance was made in the field during about 3 months of 1951, or about 12 areas, including over 100 localities in the State of Miranda, Carabobo, Yaracuy, Falcon, Lara, Trujillo, Zulia, Merida, Tachira, Bolivar, and Territory Delta Amacuro. During the course of the investigation, both in the filed and office, information was given about geology of uranium deposits, and in techniques used in prospecting and analysis. All studies and this report are designed to supplement and to strengthen the Direccion Tecnica de Geologias's program of investigation of radioactive source in Venezuela now in progress. The uranium potentialities of Los Estados de Venezuela are excellent for large, low-grade deposits of uraniferous phospahtic shales containing from 0.002 to 0.027 percent uranium; fair, for small or moderate-sized, low-grade placer deposits of thorium, rare-earth, and uranium minerals; poor, for high-grade hydrothermal pitchblende deposits; and highly possible for small, medium- to high-grade despots of carnotite-or copper-uranium bearing sandstone. Recommendations for the Venezuelan uranium program include 1) the systematic collection of a mass general radiometric data by examining sample collections, expanding the gamma-ray program, encouraging the use of Geiger counter by field geologists, and by enlisting the aid of the general public; 2) , the examination of specific areas or localities, chosen on the basis of geologic favorability from the results of the amassing of data, or obtained by hints and rumors; 3), the organization of a unit within the Direccion Tecnica de Geologica to direct, collection, and collate metric data. It is emphasized that to be most fruitful the program requires the application of sounds and imaginative geologic theory.

Description of evandromyia spelunca, a new phlebotomine species of the cortelezzii complex, from a cave in Minas Gerais State, Brazil (Diptera: Psychodidae: Phlebotominae)  

PubMed Central

Background The cave fauna of the Brazil is poorly documented, and among the insects those live or frequent caves and their adjacent environments phlebotomine sand flies call for special attention because several species are vectors of pathogens among vertebrates hosts. A new species of sand fly from Minas Gerais is described based in females and males collected in a cave of the municipality of Lassance. Results The morphological characters of the new species permit to include in the Evandromyia genus, cortelezzii complex. This complex consists of three species: Evandromyia corumbaensis (Galati, Nunes, Oshiro & Rego, 1989), Evandromyia cortelezzii (Brethes, 1923) and Evandromyia sallesi (Galvao & Coutinho, 1940). Conclusions The new species can be separate from the others of the cortelezzii complex through morphological characters of the male terminalia and female spermathecae.

Functional performance and social relations among the elderly in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil: a population-based epidemiological study.  

PubMed

This study was conducted in a probabilistic sam- ple of 2,055 elderly in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil, to examine components of social network (conjugal status and visits by the children, other relatives, and friends) and social support (satisfaction with personal relations and having persons on whom to rely) associated with limitations in performing basic activities of daily living (ADL). Multivariate analysis used the Hurdle model. Performance of ADL showed independent and statistically significant associations with social network (fewer meetings with friends and not having children) and personal support (dissatisfaction/indifference towards personal relations). These associations remained after adjusting for social and demographic characteristics, health status, and other indicators of social relations. Our results emphasize the need for greater attention to social network and social support for elderly with functional limitations and those with weak social networks and social support.

Based on the report of Ernst Hasenclever on his visit to the Gong-Soco gold mine in 1839, this article seeks to understand the labor and administrative organizational system implemented by the English gold mining companies in Minas Gerais, especially in the second half of the nineteenth century at a time when the slave-based system was in its final stages. Our objective is to show the continuity of the administrative system and the use of slave labor by the English companies from the 1830s until the end of the century, despite the pressure applied by England against the transatlantic slave trade and the prohibition of Her Majesty's subjects to own slaves anywhere in the world.

PubMed

Common mental disorders (CMD) contribute to overall burden of disease. The current study aimed to describe the prevalence of CMD among a sample of bus drivers and fare collectors in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil, and investigate whether traffic conditions and conditions inside buses were associated with the outcome. This non-probabilistic sample of 1,607 workers was estimated from the size of the effective workforce (n = 17,470). Face-to-face interviews used a digital questionnaire with online data processing. Overall prevalence of CMD was 23.6%. Bad traffic conditions lost statistical significance in the multivariate analysis, while higher income and adverse working conditions and inadequate safety remained associated with the outcome. Harmful behavior and vulnerable health situations were associated with CMD. This study of urban bus workers' health is a unique contribution that can provide backing for public policies targeting metropolitan populations. PMID:24356693

High sero-prevalence of caseous lymphadenitis identified in slaughterhouse samples as a consequence of deficiencies in sheep farm management in the state of Minas Gerais, Brazil  

PubMed Central

Background Caseous lymphadenitis (CLA), caused by Corynebacterium pseudotuberculosis, is one of the most important diseases of sheep and goats, causing considerable economic losses for herd owners. Results We assessed the seroprevalence of infection with C. pseudotuberculosis in 805 sheep from 23 sheep farms that supply slaughterhouses in the state of Minas Gerais; we also analyzed management practices that could be associated with CLA occurrence, used on these and nearby farms that also supplied animals to the slaughterhouse (n = 60). The serum samples for assaying CLA infection were taken at the slaughterhouse. Frequency of infection with C. pseudotuberculosis was estimated at 43.7%, and farm frequency was estimated at 100%. Management practices were analyzed through a questionnaire. All farmers (60/60) had extensive/semi-extensive rearing system; 70.0% (42/60) identified sheep individually; 11.7% (7/60) had periodical technical assistance; 41.7% (25/60) disinfected the facilities; 86.7% (52/60) used barbed wire fences and did not implement adequate CLA control measures; only 11.7% (7/60) of breeders reported vaccination against C. pseudotuberculosis; 13.3% (8/60) took note of animals with clinical signs of CLA; 1.7% (1/60) opened and sanitized abscesses, and isolated the infected animals; 10.0% (6/60) knew the zoonotic potential of this disease and 1.7% (1/60) of the farmers culled animals in case of recurrence of abscesses. Conclusions It can be concluded that C. pseudotuberculosis infection is widely spread in sheep flocks in Minas Gerais state in Brazil and that there is a lack of good management measures and vaccination, allowing transmission of this infectious agent throughout the production network.

Biochemical and Molecular Chitotriosidase Profiles in Patients with Gaucher Disease Type 1 in Minas Gerais, Brazil: New Mutation in CHIT1 Gene.  

PubMed

Chitotriosidase (ChT) is a human chitinase secreted by activated macrophages and its activity is used in therapeutic monitoring of Gaucher disease (GD), the most common lysosomal storage disease. About 6% of the population is homozygous for a duplication of 24 bp in exon 11 of the CHIT1 gene (dup24), which is the main polymorphism that results in the absence of ChT. As ChT enzyme activity can be used as a biomarker in GD, it is important to know the CHIT1 genotype of each patient. In this study, ChT activity and CHIT1 genotype were evaluated in 33 GD type 1 patients under treatment in the state of Minas Gerais, Brazil, and compared to healthy controls. As expected, the enzyme activity was found to be higher in GD type 1 patients than in healthy subjects. Four patients had no ChT activity. Their genotype revealed three patients (9%) homozygous for dup24 allele and one patient with two polymorphisms in exon 11: G354R and a 4 bp deletion at the exon-intron 11 boundary (g.16993_16996delGAGT), the later described for the first time in literature. Two other patients with lower ChT activity presented a polymorphism in exon 4 (c.304G>A, p.G102S), without dup24 allele. In conclusion, this study demonstrated that ChT activity can be used for therapeutic monitoring in 82% of GD patients of the state of Minas Gerais, Brazil. PMID:23430552

Seroprevalence and risk factors of toxoplasmosis in cattle from extensive and semi-intensive rearing systems at Zona da Mata, Minas Gerais state, Southern Brazil  

PubMed Central

Background Concerning the infection of humans by T. gondii, limited efforts have been directed to the elucidation of the role of horizontal transmission between hosts. One of the main routes of transmission from animals to humans occurs through the ingestion of raw or insufficiently cooked meat. However, even though the detection of T. gondii in meat constitutes an important short-term measure, control strategies can only be accomplished by a deeper understanding of the epidemiology of toxoplasmosis. The present study aimed to investigate the seroprevalence of toxoplasmosis in cattle from Zona da Mata, Minas Gerais, Brazil, and to identify associated risk factors, through an epidemiological investigation. Methods The animals studied (Bos indicus, breed Nelore or Gir) were reared in the Zona da Mata micro-region and killed at a commercial slaughterhouse at Juiz de Fora, Minas Gerais state. The animals came from 53 cattle farms with extensive (predominantly pasture feeding management) or semi-intensive (food management based on grazing, salt mineral and feed supplementation) rearing systems. Blood samples were collected from 1200 animals, and assigned to Indirect Fluorescent Antibody Test. Results When analyzing IgG anti-T.gondii we found an overall seroprevalence of 2.68%. In Brazil prevalences vary from 1.03% to 60%. Although in the present study, the seroprevalence per animal is considered low compared to those observed in other studies, we found out that of the 53 farms analyzed, 17 (34.69%) had one or more positive cattle. It is a considerable percentage, suggesting that the infection is well distributed through the Zona da Mata region. The results of the epidemiological investigation showed that the main risk factors of Toxoplasma gondii infection are related to animal management and to the definive host. There was a relationship between the number of seropositive cattle and the presence and number of resident cats, presence and number of stray cats, presence of cats walking freely, rat control by using cats and feed storage. Conclusion These results may contribute to the development of preventive strategies in Brazil and other developing countries were extensive and semi-intensive cattle rearing systems are very widespread and the efforts to control this important zoonotic disease have attained little success.

EVIDENCE OF Leishmania (Leishmania) infantum INFECTION IN DOGS FROM JUIZ DE FORA, MINAS GERAIS STATE, BRAZIL, BASED ON IMMUNOCHROMATOGRAPHIC DUAL-PATH PLATFORM (DPP®) AND PCR ASSAYS.  

PubMed

In Brazil, domestic dogs are branded as the primary reservoir for zoonotic visceral leishmaniasis, due to the clear positive correlation observed between human and canine infection rates. This study aimed to carry out a serological survey of canine visceral leishmaniasis (CVL) in dogs housed at a public kennel in the municipality of Juiz de Fora, Minas Gerais State, Brazil, using the immunochromatographic TR DPP® CVL rapid test. Additionally, conventional and/or real time PCR assay was used to detect and confirm L. infantum infection in the DPP positive dogs only. Of the 400 dogs studied, most did not present clinical signs for CVL (p < 0.05), and fifteen (3.8%) were seropositive in the DPP test. There was no statistically significant difference between the DPP seropositive dogs and the clinical signs of the disease (p > 0.05). Both conventional and real time PCR tests confirmed L. infantum infection in nine (75.0%) of the twelve DPP seropositive dogs that remained alive during the follow-up period. This study is the first seroepidemiologic survey of CVL held in the city of Juiz de Fora, and the results reinforce the idea that this disease is currently in a process of expansion and urbanization in Brazil. Furthermore, this study highlights the use of the DPP test as an alternative for diagnosing CVL in large and mid-sized cities, due to its ease of implementation. PMID:24879001

The scope of this article is to evaluate the nutritional status, body composition and tumor characteristics of 31 patients with breast cancer attended at the Mastology Service of Hospital das Clínicas of the Federal University of Minas Gerais. Dietary data were obtained from the 24-hour dietary recall in the pre-operative state and analyzed by the DietWin Professional 2008 Nutrition Software. Body composition was assessed by bioelectrical impedance analysis. The tumor characterization data were collected from medical records. The mean age of patients was 50.75 ± 14.34 years. Excess body weight was found in 58% and waist circumference greater than 80 cm in 64.5% of patients Excessive consumption of oils and sugars was observed in 90.3% and 83.8%, respectively. Most had low intakes of calcium and vitamins B6, B12 and A. The predominant diagnosis was type II histological grade invasive ductal carcinoma in stage II or III. The prevalence of overweight and inadequate dietary intake demonstrate the need for individualized nutritional guidance and monitoring to improve the prognosis and quality of the life of patients.

[Characterization of Rickettsia spp. circulating in a silent peri-urban focus for Brazilian spotted fever in Caratinga, Minas Gerais, Brazil].  

PubMed

The present study was intended to characterize Rickettsia spp. circulating in arthropod vectors in Caratinga, Minas Gerais, Brazil, by PCR and to investigate the presence of antibodies against the spotted fever Rickettsiae group (SFRG) in dogs and horses. 2,610 arthropods were collected and taxonomically identified. DNA samples obtained from these vectors were submitted to PCR and cycle-sequenced. Ctenocephalides and Amblyomma cajennense showed sequences presenting 100.0% homology with R. felis. A sequence obtained from Rhipicephalus sanguineus showed 99.0% homology with R. felis, and a sequence from A. cajennense showed 97.0% homology with R. honei and R. rickettsii. Canine (73) and equine (18) serum samples were tested by indirect fluorescent antibody (IFA) using R. rickettsii antigen. Only three of the equine sera tested (17.0%) had positive antibody titers. Molecular detection of rickettsiae species potentially pathogenic to humans in arthropod vectors and the presence of seroreactivity to SFRG in horses show the risk of transmission of rickettsiosis in this area and the need to maintain continuous epidemiological surveillance for rickettsial diseases.

Flight height preference for oviposition of mosquito (Diptera: Culicidae) vectors of sylvatic yellow fever virus near the hydroelectric reservoir of Simplício, Minas Gerais, Brazil.  

PubMed

In this study, the oviposition behavior of mosquito species exhibiting acrodendrophilic habits was investigated. The study was conducted near the Simplicio Hydroelectic Reservoir (SHR) located on the border of the states of Minas Gerais and Rio de Janeiro, Brazil. Samples were collected using oviposition traps installed in forest vegetation cover between 1.70 and 4.30 m above ground level during the months of April, June, August, October, and December of 2011. Haemagogus janthinomys (Dyar), Haemagogus leucocelaenus (Dyar and Shannon), Aedes albopictus (Skuse), and Aedes terrens (Walker) specimens were present among the collected samples, the first two of which being proven vectors of sylvatic yellow fever (SYF) in Brazil and the latter is a vector of dengue in mainland Asia. As the data set was zero-inflated, a specific Poisson-based model was used for the statistical analysis. When all four species were considered in the model, only heights used for egg laying and months of sampling were explaining the distribution. However, grouping the species under the genera Haemagogus Williston and Aedes Meigen showed a significant preference for higher traps of the former. Considering the local working population of SHR is very large, fluctuating, and potentially exposed to SYF, and that this virus occurs in almost all Brazilian states, monitoring of Culicidae in Brazil is essential for assessing the risk of transmission of this arbovirus.

Spotted Fever Group Rickettsia in Small Rodents from Areas of Low Endemicity for Brazilian Spotted Fever in the Eastern Region of Minas Gerais State, Brazil  

PubMed Central

We investigated the humoral immune response against different species of Rickettsia in serum samples from small rodents collected in two areas of a silent focus for Brazilian spotted fever in the eastern region of Minas Gerais State, Brazil. Sera samples were analyzed by indirect immunofluorescence assay using antigens from Rickettsia species of the spotted fever, ancestral, and transition groups. Titers ? 1:64 were considered positive. In Santa Cruz do Escalvado, 94% (30 of 32) of the samples collected from Rattus rattus, 22% (5 of 23) from Nectomys squamipes, and 80% (4 of 5) from Akodon sp., reacted by indirect immunofluorescence assay with Rickettsia antigens of the spotted fever group. In the municipality of Pingo D'Água, 84% (26 of 31) of the samples collected from R. rattus, 86% (6 of 7) of the samples from Oryzomys subflavus, 86% (6 of 7) from N. squamipes, and 100% (1 of 1) from Bolomys sp. contained antibodies that reacted with rickettsial antigens of the spotted fever group. These results demonstrated the previous exposure of small rodents to spotted fever group Rickettsia, suggesting the participation of these animals in the natural history of these rickettsiae in this region.

[From guidelines to practice: evaluation of the pediatric care provided by a service of secondary reference in the north of the State of Minas Gerais].  

PubMed

In the State of Minas Gerais, the Secondary Reference Viva Vida Centers (CVVRS) are one of the strategies deployed to tackle the problems in child health. This study sought to evaluate pediatric care provided in a CVVRS, using the guidelines defined when it was set up as a benchmark. A quantitative-qualitative approach was adopted, which included a cross-sectional study with stratified random sampling of 385 medical records of children registered with the program between 2007 and 2009, and analysis of focus groups with strategic actors of the initiative. There were divergences between the user profiles and the target audience in terms of age, hometown and clinical characteristics. Access and use of the service differed depending on the town, due to problems of misinformation concerning the proposal, difficulty of transportation and the fragility of the health network. The centers are considered an innovative and important initiative for the expansion and organization of the health network, though the intended logic is not effectively seen in practice. Interventions for articulation between the network services and adaptation of the agreed guidelines to the regional specificities are necessary. PMID:23752544

High-Precision Locations and the Stress Field from Instrumental Seismicity, Moment Tensors, and Short-Period Mechanisms through the Mina Deflection, Central Walker Lane  

NASA Astrophysics Data System (ADS)

The Mina Deflection (MD) region of the central Walker Lane of eastern California and western Nevada, is a complex zone of northeast-trending normal, and primarily left-lateral strike-slip to oblique-slip faulting that separates the Southern Walker Lane (SWL) from a series of east-tilted normal fault blocks in the Central Walker Lane (CWL) (Faulds and Henry, 2008; Surpless, 2008). The MD accommodates the transfer of right-lateral strike-slip motion from northwest-striking faults in the SWL to a series of left-stepping northwest-striking right-lateral strike-slip faults in the CWL, east of the Wassuk Range near Hawthorne, NV. The ~50 km wide ~80 km long right-step is a distinct transition in regional physiography that has been attributed to strain accommodation through pre-Cenozoic lithospheric structures. Several slip transfer mechanisms have been proposed within the MD, from clockwise rotation of high-angle fault blocks (Wesnousky, 2005), to low-angle displacement within the Silver Peak-Lone Mountain complex (Oldow et al., 2001), and curved fault arrays associated with localized basins and tectonic depressions (Ferranti et al., 2009). The region has been a regular source of M4+ events, the most recent being an extended sequence that included twenty-seven M 3.5+ earthquakes (largest event M 4.6) south of Hawthorne in 2011. These earthquakes (< 5 km depth) define shallow W-dipping (dip ~56°) and NW-dipping (dip ~70°) normal faulting constrained by moment tensor (MT) solutions and earthquake relocations. Temporary stations deployed in the source area provide good control. A distributed sequence in 2004, between Queen Valley and Mono Lake, primarily associated with the Huntoon Valley fault, included three M 5+ left-lateral strike-slip faulting events. A 1997 sequence in northern Fish Lake Valley (east of the White Mountains), with mainshock Mw 5.3 (Ichinose et al., 2003), also showed high-angle northeast-striking left-lateral strike-slip motion. Historical events include the 1934 M 6.5 Excelsior Mountains event south of Mina, NV, and the 1932 M 7.1 Cedar Mountains earthquake east of the Pilot Mountains. Another persistent feature in the seismicity is an ~40 km long arcuate distribution of activity extending from approximately Queen Valley, north of the White Mountains, to Mono Lake that appears to reflect a southwestern boundary to northeast-striking structures in the MD. Here we develop high-precision relocations of instrumental seismicity in the MD from 1984 through 2012, including relocations of the 2004 sequence, and account for the historical seismic record. MT solutions from published reports and computed from recent M 3.5+ earthquakes as well as available and developed short-period focal mechanisms are compiled to evaluate the stress field to assess mechanisms of slip accommodation. Based on the complex distribution of fault orientations, the stress field varies locally northward from the SWL throughout the MD; however, in many cases, fault plane alignments can be isolated from high-precision locations, providing better constraints on stress and slip orientations.

[Evaluation of a program for the control of schistosomiasis in municipalities located on the basin of the Sao Francisco River, Minas Gerais, Brazil].  

PubMed

An evaluation of the control program on schistosomiasis (PCE/PCDEN) was performed in the region of São Francisco river in MInas Gerais. The study area comprises six municipalities, with 130,000 inhabitants and 916 localities situated in an area with 10,722 km2. The activities initiated in 1983-85 in four municipalities and in 1987 in the other two. The main measures of control were repeated treatment with oxamniquine and use of niclosamide. The prevalence of infection by Schistosoma mansoni in the first four municipalities, that was initially around 18 and 32%, dropped abruptly after the first intervention (1983/85) and remained in levels below the initial ones until the last assessment (1990-94); similar trends were observed for the proportion of infected snails. In these municipalities, the proportion of localities without infection or with prevalence below 5% increased in relation to those with higher prevalence. In the other two municipalities, with initial prevalence below 5%, there were no substantial changes in S. mansoni prevalence or proportion of infected snails; the cost benefit of the program in these municipalities need to be assessed and the priorities redirected to eradicate focal areas and prevent spread to non infected localities. The authors call attention to the difficulties in the long term of a control program based on repeated treatments. Information on factors associated with S. mansoni infection in each locality, or in groups of similar localities, would allow to develop additional measures to treatment that could last longer and be less dependent on the continuous use of chemotherapy.

Study of sand flies (Diptera: Psychodidae) in visceral and cutaneous leishmaniasis areas in the central-western state of Minas Gerais, Brazil.  

PubMed

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.

Assessment of performance of professionals in immunohematology proficiency tests of the public blood bank network of the state of Minas Gerais  

PubMed Central

Background Despite significant advances, the practice of blood transfusion is still a complex process and subject to risks. Factors that influence the safety of blood transfusion include technical skill and knowledge in hemotherapy mainly obtained by the qualification and training of teams. Objective This study aimed to investigate the relationship between professional categories working in transfusion services of the public blood bank network in the State of Minas Gerais and their performance in proficiency tests. Methods This was an observational cross-sectional study (2007-2008) performed using a specific instrument, based on evidence and the results of immunohematology proficiency tests as mandated by law. Results The error rates in ABO and RhD phenotyping, irregular antibody screening and cross-matching were 12.5%, 9.6%, 43.8% and 20.1%, respectively. When considering the number of tests performed, the error rates were 4.6%, 4.2%, 26.7% and 11.0%, respectively. The error rates varied for different professional categories: biochemists, biologists and biomedical scientists (65.0%), clinical pathology technicians (44.1%) and laboratory assistants, nursing technicians and assistant nurses (74.6%). A statistically significant difference was observed when the accuracy of clinical pathology technicians was compared with those of other professionals with only high school education (p-value < 0.001). This was not seen for professionals with university degrees (p-value = 0.293). Conclusion These results reinforce the need to invest in training, improvement of educational programs, new teaching methods and tools for periodic evaluations, contributing to increase transfusion safety and improve hemotherapy in Brazil.

The analyses showed that the use of an automated database allied with geoprocessing tools may favor control measures of VL, especially with regard to the evaluation of control actions carried out. Descriptive analyses of control measures allowed to evaluating that the information system and GIS tools promoted greater efficiency in making decisions and planning activities. These analyses also pointed to the necessity of new approaches to the control of VL in large urban centers.

Levels of Cd, Cu, Pb and V in marine sediments in the vicinity of the Single Buoy Moorings (SBM3) at Mina Al Fahal in the Sultanate of Oman.  

PubMed

Recently in the Sultanate of Oman, there has been a rapid surge of coastal developments. These developments cause metal contamination, which may affect the habitats and communities at and near the coastal region. As a result, a study was conducted to assess the level of metal contamination and its impact on the marine sediments in the vicinity of the Single Buoy Moorings 3 (SBM3) at Mina Al Fahal in the Sultanate of Oman. Marine subtidal sediment samples were collected from six different stations of the SBM3 for the period ranging from June 2009 to April 2010. These samples were then analyzed for their level and distribution of the heavy metals of cadmium (Cd), copper (Cu), lead (Pb) and vanadium (V). Overall, low concentrations of all four heavy metals were measured from the marine sediments, indicating that the marine at SBM3 is of good quality. PMID:24775070

Global Vulnerability Assessment in Santa María Tixmadeje, Estado de México, México  

NASA Astrophysics Data System (ADS)

Santa María Tixmadejé (SMT), Estado de México, Mexico is a town located very close to the Acambay-Tixmadejé fault. This fault is located in the middle of the Trans Volcanic Belt in the center of the Mexican territory and generated a large seismic event in 1912 with magnitude 6.9 which combined with the local vulnerability, caused a disaster. In this work we measure the different vulnerabilities of the SMT community: structural, economical, social and educational. In addition, we determinate the total vulnerability, by summing all estimated vulnerabilities, for the critical facilities identified in this town. Vulnerability was determined using the methodology proposed by National Oceanic Atmospheric Administration (NOAA) and by Disaster Prevention National Center (CENAPRED). Besides, we considered a minimum sample statistically significant of the total houses with a random sampling for our survey. Our results indicate that 50% of the critical facilities have high and very high and the other 50% between low and moderate level of total vulnerability. The results for independent vulnerabilities are as follows: (1) Near to 75% of the community has high and very high level of social vulnerability and the range for the another 25% is between low and moderate; (2) About 43% of the community has high and very high economical vulnerability and 57% low and moderate; (3) Approximately 38% of the population has high and very high educational vulnerability. The 62% present low and moderate vulnerability; and (4) About 42% of the community has very high structural vulnerability and 58% between low and moderate.

Resumen Este artículo compara los resultados económicos entre los inmigrantes latinoamericanos en España y Estados Unidos. Detectamos un efecto de selección por el que la mayoría de los inmigrantes latinoamericanos en España proceden de Sudamérica de un entorno de clases medias, mientras la mayoría de los inmigrantes que van a los Estados Unidos son centroamericanos de clase baja. Este efecto de selección explica las diferencias transnacionales en la probabilidad de empleo, logro ocupacional y salarios obtenidos. A pesar de las diferencias en los orígenes y las características de los latinoamericanos en ambos países, los factores demográficos, humanos y de capital social parecen operar de forma similar en ambos países; y cuando los modelos se estiman separadamente por estatus legal, descubrimos que los efectos se acentúan más entre los inmigrantes irregulares cuando se los compara con los regulares, especialmente en Estados Unidos.

An overview of a GIS method for mapping landslides and assessing landslide hazards at Río El Estado watershed, on the SW flank of Pico de Orizaba Volcano, Mexico  

NASA Astrophysics Data System (ADS)

This poster provides an overview of the on-going research project (Grant SEP-CONACYT no 167495) from the Institute of Geography at the National Autonomous University of Mexico (UNAM) that seeks to conduct a multi-temporal landslide inventory, produce a landslide susceptibility map, and estimate sediment production by using Geographic Information Systems (GIS). The Río El Estado watershed on the southwestern flank of Pico de Orizaba volcano, the highest mountain in Mexico, is selected as a study area. The catchment covers 5.2 km2 with elevations ranging from 2676.79 to 4248.2 m a.s.l. and hillslopes between 0° and 56°. The stream system of Río El Estado catchment erodes Tertiary and Quaternary lavas, pyroclastic flows, and fall deposits. The geologic and geomorphologic factors in combination with high seasonal precipitation, high degree of weathering, and steep slopes predispose the study area to landslides. The methodology encompasses three main stages of analysis to assess landslide hazards: Stage 1 builds a historic landslide inventory. In the study area, an inventory of more than 170 landslides is created from multi-temporal aerial-photo-interpretation and local field surveys to assess landslide distribution. All landslides were digitized into a geographic information system (GIS), and a spatial geo-database of landslides was constructed from standardized GIS datasets. Stage 2 Calculates the susceptibility for the watershed. During this stage, Multiple Logistic Regression and SINMAP) will be evaluated to select the one that provides scientific accuracy, technical accessibility, and applicability. Stage 3 Estimate the potential total material delivered to the main stream drainage channel by all landslides in the catchment. Detailed geometric measurements of individual landslides visited during the field work will be carried out to obtain the landslide area and volume. These measurements revealed an empirical relationship between area and volume that took the form of a power law. This relationship will be used to estimate the potential volume of material delivered to the catchment. The technique and its implementation of each stage in a GIS-based technology is presented and discussed.

Medicina integrativa en Am?rica: De qu? forma se est? practicando la medicina integrativa en los centros cl?nicos en los Estados Unidos  

PubMed Central

RESUMEN EJECUTIVO El impulso para desarrollar e implementar estrategias de medicina integrativa está enraizado en el deseo de mejorar la atención al paciente. The Bravewell Collaborative, una organización sin ánimo de lucro dedicada a la mejora de la atención sanitaria, define la medicina integrativa como “un enfoque de la medicina que coloca al paciente en el centro y se dirige al conjunto completo de influencias físicas, emocionales, mentales, sociales, espirituales y ambientales que afectan a la salud de la persona. Con una estrategia personalizada que considera las condiciones, necesidades y circunstancias únicas del paciente, utiliza las intervenciones más apropiadas de una variedad de disciplinas científicas para curar la afección y la enfermedad y ayudar a las personas a recobrar y mantener una salud óptima”. En las pasadas dos décadas, se ha documentado un número creciente de centros clínicos que proporcionan medicina integrativa, el número de facultades y escuelas médicas que enseñan estrategias integrativas, el número de investigadores que estudian intervenciones integrativas, y el número de pacientes que solicitan cuidados integrativos. Pero se desconocía si la medicina integrativa se estaba ofreciendo de manera igual, similar, o dispar. Además, mientras que los estudios anteriores se centraban en la prevalencia y el uso de la medicina complementaria o alternativa (MCA) por parte de los pacientes1,2 o de los médicos en hospitales3, enumerando la utilización de terapias MCA individuales, se había recogido muy poca información con respecto a la práctica real de la medicina integrativa que, por definición, trata a la persona en su conjunto. En 2011, The Bravewell Collaborative encargó una encuesta para determinar la forma en que la medicina integrativa se estaba practicando en los Estados Unidos: (1) describiendo las poblaciones de pacientes y las afecciones sanitarias tratadas más habitualmente; (2) definiendo las prácticas y modelos fundamentales de atención; (3) determinando cómo se reembolsaban los servicios; (4) identificando los valores y los principios subyacentes a la atención; y (5) determinando los factores principales que impulsan una implementación satisfactoria.

Physical, Structural and Operational Vulnerability of Critical Facilities in Valle de Chalco Solidaridad, Estado de Mexico, Mexico. Case of study: Avándaro, San Isidro and El Triunfo  

NASA Astrophysics Data System (ADS)

Valle de Chalco Solidaridad is located in Mexico City Metropolitan Area in Estado de Mexico, Mexico. In this town there is a sewage canal called “La Compañía”. A wall of this canal collapsed on February 5, 2010 due to heavy rains creating the flooding of four surrounding communities. It is important to point out that this area is frequently exposed to floods. In this work, we consider a critical facility as an essential structure for performance, health care and welfare within a community or/and as a place that can be used as shelter in case of emergency or disaster. Global vulnerability (the sum of the three measured vulnerabilities) of the 25 critical facilities identified in the locations of Avándaro, San Isidro and El Triunfo was assessed using the Community Vulnerability Assessment Tool developed by the National Oceanic and Atmospheric Administration (NOAA). For each critical facility we determined its operational, structural and physical vulnerabilities. For our analysis, we considered the four main natural hazards to which Valle de Chalco is exposed: earthquakes, floods, landslides and sinking. We considered five levels of vulnerability using a scale from 1 to 5, where values range from very low to very high vulnerability, respectively. A critical facilities database was generated by collecting general information for three categories: schools, government and church. Each facility was evaluated considering its location in relation to identified high-risk areas. Our results indicate that in average, the global vulnerability of all facilities is low, however, there are particular cases in which this global vulnerability is high. The average operational vulnerability of the three communities is moderate. The global structural vulnerability (sum of the structural vulnerability for the four analyzed hazards) is moderate. In particular, the structural vulnerability to earthquakes is low, to landslides is very low, to flooding is moderate and to sinking is low. Due to the location of the critical facilities, its global physical vulnerability (sum of the physical vulnerability to the four analyzed hazards) is moderate. Only three facilities have very high physical vulnerability to floods. Churches (six facilities) have the highest operational vulnerability, whereas its structural vulnerability is the lowest. Schools (13 facilities) have the lowest operational vulnerability, nevertheless, there are two schools with very high vulnerability. Regarding the six government facilities, we identified that their structural vulnerability range from moderate to high. As a result of this work, we believe in the importance of strengthening the culture of civil protection within the critical facilities of the communities of Valle de Chalco.

Community structure and productivity of the Cornwallis Estuary, Minas Basin  

NASA Astrophysics Data System (ADS)

Preliminary results of a seasonal study of the pelagic community at a station on the outer edge of the Cornwallis Estuary suggest that the seasonal variation in plankton community respiration (PCR) is related to organic inputs from nearby salt marshes. Annual phytoplankton production is low (<30 g C m -2 y -1) and exhibits a seasonal cycle very different from PCR. There is no indication that resuspension of benthic diatoms is an important energy input to the pelagic system. PCR, however, is quite high and exhibits a seasonal trend similar to the export of salt marsh detritus. Zooplankton densities (5-200 l -1) and biomass (<0.4 g m -3) appear to be much greater than could be supported by phytoplankton alone. The Cornwallis Estuary may be an estuarine system exhibiting a net export of organic matter to nearby offshore waters.

Multi-proxy analyses of a peat bog on Isla de los Estados, easternmost Tierra del Fuego: a unique record of the variable Southern Hemisphere Westerlies since the last deglaciation  

NASA Astrophysics Data System (ADS)

We have analyzed an almost 14,000 year old peat sequence on the island of Isla de los Estados (55° S, 64° W), east of Tierra del Fuego, in the core of the Southern Hemisphere Westerlies. A multitude of methods have been used: high resolution 14C dating; detailed lithologic descriptions including humification degree; loss on ignition; magnetic susceptibility; bulk density; pollen and spore analysis and determination of Aeolian sand influx. By combining proxies for wind and precipitation we have been able to reconstruct how the westerlies have varied over time in the Atlantic sector of the Southern Ocean. It shows that this westerly wind belt was most intense at the onset of the record, 13,600-13,200 cal BP, coinciding with the mid to late part of the Antarctic Cold Reversal, followed by a gradual decline. At 12,200 cal BP the westerlies seem to have shifted to a position south of Tierra del Fuego and this phase, the calmest and driest period on the island throughout the sequence, ended at 10,000 cal BP when the westerlies moved equatorward again. Since then the westerlies have been present but with a variable impact on the 55° S latitude of the Atlantic. Mostly conditions have been fairly similar to today, but occasionally with a wider or narrower and/or weaker or stronger wind belt. At 7200 cal BP wind intensity began to increase and between 4500 and 3500 cal BP these southern latitudes experienced a distinct wind and precipitation maximum, both in terms of perseverance and intensity. Our results show a both wide and strong wind belt, with possible niveo-aeolian activity in Tierra del Fuego in winter, and possibly creating milder summers around the Antarctic Peninsula. In the later part of the Holocene, expansion-contraction phases of the wind belt, especially in winter, seem to have been a common phenomenon.

Sobre el estado evolutivo de ? Pictoris  

NASA Astrophysics Data System (ADS)

Desde el descubrimiento de fuertes excesos infrarrojos en ? Pictoris, esta estrella ha sido muy estudiada y es considerada candidata a poseer un sistema planetario propio. ? Pic está rodeada de un disco asimétrico de polvo que se observa de canto y que esta vacío a distancias <= 40 AU. Esto se considera una fuerte evidencia en favor de la presencia de (al menos) un planeta gigante. Recientemente se han observado líneas de material circunestelar que se han interpretado como consecuencia de la caída de objetos cometarios sobre esta estrella. Recientemente se ha utilizado la existencia del disco de polvo para atribuir una edad corta (pre - secuencia principal) a ?Pic. Sin embargo, la evaporación de estos cometas provee suficiente polvo como para explicar la presencia del disco observado sin necesidad de edades cortas. En este trabajo mostramos que la comparación entre la tasa de impactos cometarios estimada en el Sistema Solar para diferentes etapas de su evolución y los datos observados en ? Pic indica edades avanzadas para ? Pic. Esta estimación debe tomarse con cautela ya que depende de la estructura de los sistemas planetarios. Además mostramos que, desde el punto de vista de la evolución estelar y con las incertezas presentes en la luminosidad y la temperatura efectiva, existe un continuo de edades posible para ? Pic. Sin embargo, empleando los datos provenientes de los flujos cometarios encontramos que una edad prolongada es consistente con ambos tratamientos.

Characterization of Mina?u virus (Reoviridae: Orbivirus) and pathological changes in experimentally infected newborn mice  

PubMed Central

Minaçu virus was isolated from Ochlerotatus scapularis (Diptera: Culicidae) in Minaçu, Goiás State, Brazil, in 1996. In attempting characterization of virus serological (hemagluttination inhibition, HI; indirect immunofluorescence assay, IFA), physicochemical [test for deoxycholate acid (DCA) sensitivity; polyacrylamide gel electrophoresis (PAGE)] tests and ultrastructural studies were made. Virus was also assayed in suckling mice after intracerebral inoculation of 0.02 ml and in VERO and C6/36 cells with 0.1 ml of viral suspension containing 105 LD50/ml. Inoculated and control systems were observed daily. Every 24 h, one control and two inoculated animals were killed for tissue testing, including histopathological changes by haematoxylin and eosin (HE)-stained sections, which were semi-quantified. Research into viral antigen in the tissues of mice [central nervous system (CNS), liver, heart, lungs, spleen and kidneys] was carried out by the immunohistochemical technique using the peroxidase system. The virus only replicated in VERO cells, with antigen positive by IFA. Positive complement fixation tests were only obtained using antiserum of Minaçu virus. Minaçu virus is DCA resistant; haemagglutinating activity was negative. By electronic microscopy non-enveloped virus particles were 75 nm in diameter. PAGE analysis showed Minaçu virus genome profile with 10 RNA segments. Infected, non-killed animals died 7 days after inoculation. Tissue lesions were observed in all organs, except the lungs. Intense lesions were observed in the CNS and the heart, where neurone and cardiocyte necroses, respectively, were noted. The liver, spleen and kidneys had moderate tissue changes. Viral antigens were more abundant in the CNS and the heart, and absent in the lungs. In conclusion, Minaçu virus belongs to the family Reoviridae, genus Orbivirus.

Rhipicephalus sanguineus ticks are distributed throughout the world, especially in those areas in which dogs are in close contact with humans. R. sanguineus and fleas are regarded as the main ectoparasites infesting dogs in Brazil. Besides causing direct damage during the blood feeding process, this tick species can also transmit pathogens to dogs and humans. Despite its importance in Brazil,

Phlebotomine fauna in the urban area of Timóteo, State of Minas Gerais, Brazil.  

PubMed

This work is characterized by an entomological research and an investigation on whether seasonal behaviours can be associated to the phlebotomine fauna found in the urban area of Timóteo-MG - an endemic focus of tegumentary leishmaniasis (TL). The analysis of the seasonal behaviour of sand flies has taken into account the following climatic variables: rainfall, relative humidity and temperature. Automatic light traps were installed in households between 2009 and 2010. The sand fly species with the highest number captured was Lutzomyia whitmani (66.5%), a TL vector species, whose abundance has provided strong evidences that this species is the main vector of TL in the municipality of Timóteo, with its cycle of transmission developing in its urban area. Amongst the results observed in the analyses of seasonal behaviour, only temperature conveyed particular association between seasonal occurrence of sand flies and climate variables. The findings of this study may assist the local epidemiological surveillance agency in defining strategies and directing efforts for controlling these insects. PMID:24613154

Canine visceral leishmaniasis in the Krenak indigenous community, Resplendor, Minas Gerais State, Brazil, 2007.  

PubMed

The authors conducted a cross-sectional study of the local canine population in the Krenak indigenous community to detect parasites of the genus Leishmania and identify the circulating species and the proportion of asymptomatic dogs, while investigating associations between canine infection and the dogs' sex, age, and hair length. A seroepidemiological survey was performed, including 63 dogs. All the animals underwent clinical examination to verify the presence of characteristic signs, and serum samples were taken for serological tests (ELISA, IIF). Infected dogs culled by the health service were necropsied and the material was analyzed using molecular diagnostic techniques. The cross-sectional study detected a 46% prevalence rate, and the circulating species was Leishmania (L.) chagasi. The statistical analysis showed no association between infection and the independent variables. The study generated data on the epidemiological situation with canine infection in the area, which was previously unknown. PMID:21519710

Epidemiology of visceral leishmaniasis in a reemerging focus of intense transmission in Minas Gerais State, Brazil.  

PubMed

This study was developed in the urban area of Governador Valadares, a reemerging focus of intense transmission of visceral leishmaniasis (VL) in Brazil, presenting 86 human cases of VL from 2008 to 2011. The disease prevailed in males (73.2%) with most patients between 0 and 9 years (44.1%) and a lethality rate of 16.2%. A canine survey was carried out on 16,529 domestic dogs in 35 districts in the area and it showed that 30.2% of them (4,992 dogs) were positive for VL by serum assays. Prevalence ratios for canine VL varied between 13.6% and 53.4%. The clinical exam of 343 seropositive dogs showed that 49.9% of them were considered symptomatic, with larger prevalence of canine VL being in short-furred animals (90%). The entomological survey was performed in eight districts, where 2,539 phlebotomines were captured, preferentially in the peridomicile (84.5%). Lutzomyia longipalpis was the predominant species (90%) suggesting its participation in the VL transmission in the area. The correlation between canine prevalence and L. longipalpis density was evaluated. PMID:24000322

EVALUATION OF ANTIMICROBIAL AND CYTOTOXIC ACTIVITIES OF PLANT EXTRACTS FROM SOUTHERN MINAS GERAIS CERRADO  

PubMed Central

The antimicrobial activity of plant hidroethanolic extracts on bacteria Gram positive, Gram negative, yeasts, Mycobacterium tuberculosis H37 and Mycobacterium bovis was evaluated by using the technique of Agar diffusion and microdilution in broth. Among the extracts evaluated by Agar diffusion, the extract of Bidens pilosa leaf presented the most expressive average of haloes of growth inhibition to the microorganisms, followed by the extract of B. pilosa flower, of Eugenia pyriformis' leaf and seed, of Plinia cauliflora leaf which statistically presented the same average of haloes inhibitory formation on bacteria Gram positive, Gram negative and yeasts. The extracts of Heliconia rostrata did not present activity. Mycobacterium tuberculosis H37 and Mycobacterium bovis (BCG) appeared resistant to all the extracts. The susceptibility profile of Candida albicans and Saccharomyces cerevisiae fungi were compared to one another and to the Gram positive Bacillus subtilis, Enterococcus faecalis and the Gram negative Salmonella typhimurium bacteria (p > 0.05). The evaluation of cytotoxicity was carried out on C6-36 larvae cells of the Aedes albopictus mosquito. The extracts of stem and flower of Heliconia rostrata, leaf and stem of Plinia cauliflora, seed of Anonna crassiflora and stem, flower and root of B. pilosa did not present toxicity in the analyzed concentrations. The highest rates of selectivity appeared in the extracts of stem of A. crassiflora and flower of B. pilosa to Staphylococcus aureus, presenting potential for future studies about a new drug development.

We analyzed the sandflies around houses and domestic animal shelters located in residences close to forests in localities on the banks of the Araguari River, Uberlândia, MG, from February 2003 to November 2004. 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. More studies of their occupation in anthropic environments need to be made. PMID:23563760

Challenges of Including the Mina Route in the Nevada Rail Alignment Environmental Impact Statement  

SciTech Connect

The Department of Energy's Office of Civilian Radioactive Waste Management is developing the Yucca Mountain repository for the disposition of spent nuclear fuel (SNF) and high level radioactive waste (HLW). Part of that development is the transportation infrastructure needed to ship SNF and HLW from 77 sites around the country to the repository. A Record of Decision was issued in 2004 to use mostly rail as the mode of transport both nationally, and in the State of Nevada. No rail access exists to the Yucca Mountain site, so a Rail Alignment Environmental Impact Statement (RA-EIS) is being prepared to address the impacts associated with connecting existing track in Nevada to Yucca Mountain. Late in the preparation of the Draft RA-EIS, an option to consider an additional alignment alternative was introduced. This paper describes the consideration given to the new alternative and describes how it is being incorporated into the RA-EIS. (authors)

As these stars are embedded in dense and optically thick circumstellar media, the determination of the spectral type and luminosity class of the central objects is quite difficult. As a consequence, their evolutionary stage and distances present huge uncertainties. In this work we study 4 B[e] stars and discuss their stellar fundamental parameters and evolutionary stages using the BCD spectrophotometric system. FULL TEXT IN SPANISH

Financial impact of nosocomial infections in the intensive care units of a charitable hospital in Minas Gerais, Brazil  

PubMed Central

Objective Infections in intensive care units are often associated with a high morbidity and mortality in addition to high costs. An analysis of these aspects can assist in optimizing the allocation of relevant financial resources. Methods This retrospective study analyzed the hospital administration and quality in intensive care medical databases [Sistema de Gestão Hospitalar (SGH)] and RM Janus®. A cost analysis was performed by evaluating the medical products and materials used in direct medical care. The costs are reported in the Brazilian national currency (Real). The cost and length of stay analyses were performed for all the costs studied. The median was used to determine the costs involved. Costs were also adjusted by the patients' length of stay in the intensive care unit. Results In total, 974 individuals were analyzed, of which 51% were male, and the mean age was 57±18.24 years. There were 87 patients (8.9%) identified who had nosocomial infections associated with the intensive care unit. The median cost per admission and the length of stay for all the patients sampled were R$1.257,53 and 3 days, respectively. Compared to the patients without an infection, the patients with an infection had longer hospital stays (15 [11-25] versus 3 [2-6] days, p<0.01), increased costs per patient in the intensive care unit (median R$9.763,78 [5445.64 - 18,007.90] versus R$1.093,94 [416.14 - 2755.90], p<0.01) and increased costs per day of hospitalization in the intensive care unit (R$618,00 [407.81 - 838.69] versus R$359,00 [174.59 - 719.12], p<0.01). Conclusion Nosocomial infections associated with the intensive care unit were determinants of increased costs and longer hospital stays. However, the study design did not allow us to evaluate specific aspects of cause and effect.

Evaluation of the conjunctival swab for canine visceral leishmaniasis diagnosis by PCR-hybridization in Minas Gerais State, Brazil.  

PubMed

The visceral leishmaniasis (VL) in Brazil is caused by Leishmania chagasi (L. infantum) and dogs are considered to be the main domestic reservoir. The epidemiological control involves the elimination of infected dogs. Therefore, the correct diagnosis is very important in order to avoid the disease transmission or unnecessary culling of dogs. Recently, an antileishmanial vaccine for dogs was licensed and commercialized in Brazil. Vaccinated dogs test positive in the conventional serological tests, rendering these assays useless for control programs involving vaccinated animals. The Polymerase Chain Reaction (PCR) is an attractive alternative to the diagnosis in this context; but non-invasive samplings have great importance because they are simpler, painless and less resisted by dog-owners. This study aimed at evaluating the conjunctival swab (CS) for canine VL diagnosis by the PCR-hybridization procedure. Two groups of 23 seropositive dogs were used. CS samples were obtained from both eyes of each animal. The DNA extraction from CS was performed by the phenol chloroform method in group 1 and by boiling in group 2. In addition, blood was collected from each animal so that 30 microl was spotted onto filter paper (FP) and 1.0 ml was treated to obtain the buffy coat (BC). The DNA extraction from the BC and FP was accomplished by identical procedures in both groups using commercial kits. The PCR positivities for both groups 1 and 2 were, respectively: 73.9% and 52.2% (CS), 13% and 30.4% (BC), 8.7% and 17.4% (FP). The hybridization step increased the positivities for: 91.3% and 65.2% (CS), 21.7% and 34.8% (BC), 30.4% and 43.5% (FP), respectively. The highest frequency of positivity was obtained by the association between CS and DNA extraction by phenol chloroform. This approach can be very useful for diagnosis of canine leishmaniasis and could be applied to the follow-up and regular screening of vaccinated dogs. PMID:18242866

Denudation rates of the Southern Espinhaço Range, Minas Gerais, Brazil, determined by in situ-produced cosmogenic beryllium-10  

NASA Astrophysics Data System (ADS)

To investigate denudation rates in the southern part of the Espinhaço Range (central-eastern Brazil) and to understand how this important resistant and residual relief has evolved in the past 1.38 My, cosmogenic 10Be concentrations produced in situ were measured in alluvial sediments from the three main regional basins, whose substratum is composed primarily of quartzites. The long-term denudation rates (up to 1.38 My) estimated from these measurements were compared with those that affect the western (São Francisco River) and eastern (Doce and Jequitinhonha Rivers) basins, which face the West San Francisco craton and the Atlantic, respectively. Denudation rates were measured in 27 samples collected in catchments of different sizes (6-970 km2) and were compared with geomorphic parameters. The mean denudation rates determined in the northern part are low and similar to those determined in the southern part, despite slightly different geomorphic parameter values (catchment relief and mean slope). For the southern catchments, the values are 4.91 ± 1.01 m My- 1 and 3.65 ± 1.26 m My- 1 for the Doce and São Francisco River basins, respectively; for the northern catchments, they are 4.40 ± 1.06 m My- 1 and 3.96 ± 0.91 m My- 1 for the Jequitinhonha and São Francisco River basins, respectively. These low values of denudation rates suggest no direct correlation if plotted against geomorphic parameters such as the catchment area, maximum elevation, catchment relief, average relief and mean slope gradients. These values show that the regional landscape evolves slowly and is strongly controlled by resistant lithology, with similar erosional rates in the three studied basins.

[Equity in the health sector: evaluation of public policy in Belo Horizonte, Minas Gerais State, Brazil, 1993-1997].  

PubMed

This article evaluates government measures to reduce inequity in the health sector in Belo Horizonte from 1993 to 1997. Our hypothesis is that a municipal administration committed to equity can reduce disparities in health with the support of the Unified National Health System (SUS). The methodology used an urban quality of life index in Belo Horizonte to detect social inequalities in living conditions, as well as differences between the component indices in the infant mortality rate. Other municipal measures were assessed according to the investment resulting from the implementation of a participatory local budget and open planning process. The urban quality of life index appeared to be an appropriate measure for orienting municipal administration. The infant mortality rate proved to be a good indicator for measuring inequality in health. There was a reduction in IMR and mortality reducing gaps in the districts studied. We observed greater investment of physical and financial resources in the districts with the lowest urban quality of life index, and it can thus be stated that the municipal administration reduced the prevailing inequalities.

Raising awareness about soil diversity: The Education Programme of the Earth Sciences Museum Alexis Dorofeef, Minas Gerais, Brazil  

NASA Astrophysics Data System (ADS)

Soils are usually overlooked as part of geodiversity and geoheritage. Increasing the public awareness about soils is a key issue in our changing world. Furthering public awareness involves developing a better understanding of soils, their functions, importance for environment and society, as well as a personal and collective commitment in the stewardship and protection from degradation and loss. This presentation describes the Soil and Environmental Education and Outreach Programme of the Alexis Dorofeef Earth Sciences Museum of the Soil University Department in Viçosa, Brazil. The program has developed different activities linked to formal and non formal education and its main audience are basic education teachers, school children and the general public. The museum acts in different and diverse fronts, supported on a pedagogical background based on Paulo Freire's educational approach, the social-constructivism, which considers social inclusion, knowledge building, horizontal learning and collective action. In its early years, the museum was mainly focused on formal education and this changed with time as our action was reshaped into a broader outreach action stimulated by the new Brazilian government. The museum's indoor activities consist of accompanied thematic visits, hands on experiments, basic school teacher's courses, development of learning materials and methods and professional training. Beyond of the Museum space local interdisciplinary projects with basic education schools are run along with temporary expositions coupled with short courses and workshops with farmers and social movements. We present the results of the changes in awareness about soils among three main groups: school teachers, basic education children and general public. After 10 years of activities, the Soil Education action of the Museum is recognized and well spread among school communities in the town and its neighbourhood. Many school teachers approach the contents and methodologies they learned at the museum, as well as many of the students that did their practical's at the museum do. As a side result, the Soil Education Program triggered the broadening of the museum themes into three main conceptual lines: Earth's dynamics, Natural resources: use and environmental impacts and, Soils: know to conserve. Today the Museum is spreading its knowledge about soil throughout the region, by means of temporary expositions and educational activities. Despite its achievements, the Museum still faces the challenge to broaden its action, reaching different and wider publics, making both the idea of visiting a museum and the knowledge about soils more popular.

[A study of the overall burden of oral disease in the state of Minas Gerais, Brazil: 2004-2006].  

PubMed

Oral disease is a major public health problem due to its prevalence in practically all age groups. This is a study of the overall burden of dental caries, edentulism and periodontal disease. The Disability-Adjusted Life Year (DALY) indicator was used as it simultaneously measures the impact of mortality and of health problems that affect the quality of life. The overall burden of oral diseases was analyzed in absolute terms and in rates per 1000 inhabitants. The number of Years Lived with Disability (YLD) due to dental caries was 4,489. An estimated 33,888 YLD were lost due to edentulism, with a rate of 1.8/1000 (2.2/1000 among women). An estimated 3217 YLD were lost due to periodontal disease, with a rate of 0.2/1000 for both sexes. Edentulism was the condition that contributed most to the overall burden of oral diseases and is more frequent among women. Higher rates of edentulism and periodontal disease were found in persons aged 45-69 years, while dental caries was more frequent from 15-49 years. The overall burden of oral disease studies represent an important aspect of health diagnosis, integrating both fatal and non-fatal outcomes. Furthermore, these studies provide highly relevant information for preventive and therapeutic policy making. PMID:25014296

[Biology of Methona themisto (Hübner, 1818) (Lepidoptera, Nymphalidae, Ithomiinae) adults in public plazas in Uberlândia, Minas Gerais, Brazil].  

PubMed

From April 1992 to September 1993 Methona themisto (Hübn.) adults were weekly marked and recaptured in two downtown plazas in Uberlândia, MG. Females accounted for a third of the 637 individuals marked. Nearly 10% of the butterflies were recaptured, with the maximum residence time of 62 days. The presence of the larval host plant (Brunfelsia uniflora (Pohl) D. Don, Solanaceae) in one of the plazas enhanced a higher abundance of the butterfly throughout the research and a higher proportion of new individuals, and frequency of migrants than the other plaza which lacked the host plant. Methona themisto adults were active through the sampling period with overlapping generations. Its abundance in plazas with polluted air and exotic flora, long adult life, and tolerance to humans in its vicinities place M. themisto among the ones indicated to have its life conditions improved in downtown areas of brazilian cities. Simple managing practices which benefit the lepitopteran are suggested. PMID:23505646

Current situation and perspectives regarding human Chagas disease in midwestern of the state of Minas Gerais, Brazil.  

PubMed

Recognising the importance of Chagas disease in Brazil, Bambuí set up epidemiological surveillance for Chagas disease in 1974 and was the first municipality to do so. To ascertain the current epidemiology of Chagas disease in this municipality, 1.782 blood samples from the general population were analysed; 7.7% of samples were found to be seropositive for Chagas disease. A strong positive correlation between increasing age and Chagas disease was evident in both genders, with the highest prevalence in individuals aged over 60 years. Clinically, the cardiodigestive form of Chagas disease was the most common in these samples. These data confirm the interruption of Trypanosoma cruzi transmission, in parallel with a still important residual morbidity of Chagas disease in the county, thus supporting political decisions that will prioritise epidemiological surveillance and medical treatment of Chagas disease in the coming years.

[Chagas disease in Virgem da Lapa, Minas Gerais, Brazil. IV. Clinical and epidemiological aspects of left ventricular aneurism].  

PubMed

The study aimed at the evaluation of the clinical and epidemiological characteristics of the aneurysm found in the left ventricle in chronic Chagas' disease patients. Three hundred, eighty eight people (298 chagasic patients and 90 randomly selected healthy individuals) were submitted to echocardiography. The ventricular function was assessed in the M mode by calculating the fraction of ejection, and in the bidimensional mode by analyzing he global systolic function. Segmental contractility was evaluated according to the method described by American Society of Echocardiography. Aneurysm of the left ventricle was diagnosed in 58 (18.8%) patients, all from the chagasic population. From these, 38 (12.7%) were found in the apical segment; 10 (3.4%) in the interventricular septum; and 2 (0.7%) each in the posterior wall; the inferior wall; apico-septal; and inferior-posterior. We could not observe any significant difference for the aneurysm frequencies in relation to age group, gender and race, and no association between aneurysm and arterial hypertension could be made. Of the 56 individuals presenting aneurysm, 55 (98.2%) were symptomatic with predominant palpitations; 53 (94.6%) showed an aberrant ECG with predominant ventricular extra-systoles followed by changes in conduction; and 34 (60.%) showed an impairment of the ventricular function, regardless of the affected segment. In view of these results we consider the apical aneurysm of the left ventricle as a marker of Chagas' disease and as an indicator of high morbidity of the human T. cruzi infection in Virgem da Lapa.

Diagnosis of severe silicosis in young adults working in stone polishing and mining in Minas Gerais, Brazil.  

PubMed

This study describes the occurrence of silicosis in a group of stone polishing and/or mining workers who began working under the age of 18, the minimum age in Brazil for working in hazardous or unhealthy conditions. The design is that of a case series with medical follow up via a surveillance program that included medical and occupational histories, chest radiography interpreted according to International Labour Organization (ILO) Classification, and spirometry. The findings call attention to the importance of the problem of silicosis, which persists in the region despite new production technologies, legal requirements, and initiatives to protect workers. Silicosis is a public health problem that must be addressed by the implementation of public policies to improve working conditions and ensure children and teenagers are kept away from hazardous work. While Brazil has started to be a part of the global effort to eliminate silicosis and the worst forms of child labor, there are still problems that must be addressed. PMID:20465059

[Dipterans of forensic interest in two vegetation profiles of cerrado in Uberlândia, State of Minas Gerais, Brazil].  

PubMed

Carrion breeding insects may be of great utility in crimes briefing. Studies on forensic entomology are restricted to few localities in Brazil and very few of them were done in the cerrado vegetation (a type of Savannah) until now. This work aimed to survey the main species of dipterans associated with the decomposition process of Sus scrofa and the insect succession pattern in carcasses in the Cerrado. The study was carried out in the dry and humid season of the year, in two cerrado vegetation profiles in Uberlândia, MG. Two pig carcasses were placed in each vegetation profile and time period of the year. The decomposition process was slower and insects were more abundant in the dry season. Differences in temperature, air humidity and pluvial precipitation seemed to be the main physical factors responsible for the differences in the time of decomposition of the pig carcasses between the two seasons. Fourteen species of dipterans (59,467 specimens) bred in the decomposing carcasses. Chrysomya albiceps (Wiedemann) was the species more abundantly breed in the two periods. The other species that breed in the carcasses were: C. putoria (Wiedemann), Hemilucilia segmentaria(Fabricius), Lucilia eximia(Wiedemann) (Calliphoridae), Peckia (Pattonella) intermutans(Walker), Peckia (Squamatoides) trivitatta(Curran), Sarcodexia lambens(Wiedemann) (Sarcophagidae), Musca domestica(L.), Ophyra aenescens(Wiedemann), Stomoxys calcitransL. (Muscidae), Fannia pusio(Wiedemann), Fannia sp. (Fanniidae), Hermetia illuscens L. (Stratiomyidae) and Phoridae sp. The Cerrado of this region presents many dipterans potential forensic indicators.

Ecological distribution of stream macroalgal communities from a drainage basin in the Serra da Canastra National Park, Minas Gerais, Southeastern Brazil.  

PubMed

Twelve stream segments were sampled four times in 1998-1999 (one sampling per season) in the drainage basin of the upper São Francisco River (19 masculine 45'-21 masculine 25'S, 49 masculine 05'-51 masculine 30'W), situated in Serra da Canastra National Park, at altitudes ranging from 1,175 to 1,400 m. The macroalgae survey resulted in 30 species, with a predominance of Cyanophyta (12 species = 40%) and Chlorophyta (11 species = 36.5%) and a lower proportion of Rhodophyta (seven species = 23.5%). Two species, Klebsormidium rivulare (Chlorophyta) and Kyliniella latvica (Rhodophyta), were new records for Brazil. Capsosira sp. and Stigonema sp. (Cyanophyta) and the "Chantransia" stage of Batrachospermum (Rhodophyta) were the most widespread macroalgae, occurring in six sampling sites, whereas 11 species were found at only one site. The proportion of macroalgal morphological types were as follows: mats (33%), free filaments (27%), gelatinous filaments (27%), crusts (7%), tufts (3%), and gelatinous colonies (3%). The flora revealed few species in common (4%-8%) with stream macroalgae from other Brazilian regions. The macroalgal communities proved to have species richness values close to the highest values reported in previous studies. The patterns typical for stream macroalgal communities (patchy distribution and dominance of few species) were also found in this basin. However, the stream variables most influential in macroalgal distribution in this study (rocky substratum, low pH, high COD, water color, and current velocity) were essentially the same that best describe the limnological characteristics of this lotic ecosystem. In addition, this combination of variables differed sharply from results of previous studies in other Brazilian stream ecosystems. PMID:15029374

Environmental factors and benthic Oligochaeta (Annelida, Clitellata) assemblages in a stretch of the Upper São Francisco River (Minas Gerais State, Brazil).  

PubMed

The Oligochaeta forms an important part of the macroinvertebrates inhabiting sediments of lotic ecosystems. It has an important role in the cycling of matter and energy transfer in these environments. The aim of this study is to analyse limnological variables, their influence on the structure and diversity of benthic oligochaete taxocenosis in a stretch of the Upper São Francisco River and its tributary the Piumhi River. Samples were taken in two climatic periods, the dry season in October 2006 and 2007 and the rainy season in March 2007 and 2008 at three points along the Piumhi River and six points along the São Francisco River. The sediment of the São Francisco consisted predominantly of sand and clay, whereas the sediment of the Piumhi was mainly sandy. Six species of oligochaete occurred in the Piumhi River while seven were found in the São Francisco. Of these, Pristina synclites Stephenson, 1925, Pristina americana Cernosvitov, 1937, Bothrioneurum sp. Stolc, 1888 and Limnodrilus hoffmeisteri Claparede, 1862 occurred in the sediment of both rivers. L. hoffmeisteri showed the highest numerical abundance in the Piumhi River and Brinkhurstia americana (Brinkhurst, 1964) and L. neotropicus Cernosvitov, 1939 were the most abundant species in the São Francisco River. The highest oligochaete density was recorded in the Piumhi during the dry seasons. Canonical correspondence analyses (CCA) of sediment characteristics explained most of the data variability and the association of the presence of oligochaete species in the Piumhi and São Francisco Rivers with the limnological variables (grain size composition and total nitrogen and phosphorus concentrations in the sediment).

Proteocephalid cestode infection in alien fish, Cichla piquiti Kullander and Ferreira, 2006 (Osteichthyes: Cichlidae), from Volta Grande reservoir, Minas Gerais, Brazil.

This work evaluates the variation of the parasitological indexes in 114 Cichla piquiti Kullander and Ferreira, 2006 (tucunaré) infected by two proteocephalid species (Cestoda) for the period of August 1999 to June 2001 in the Volta Grande reservoir, MG, Brazil. The relation between the parasitosis with rainfall and water quality (pH, electric conductivity, oxygen, chlorophyll, transparency and temperature) is discussed. Prevalence of Proteocephalus macrophallus (Diesing, 1850) and/or P. microscopicus (Woodland, 1935) was 83.3%, mean intensity 110.8 and mean abundance 100.7 during the period. A hundred percent prevalence was reported in August and December 1999, April and December 2000 and June 2001. The largest mean intensities of 122.7 (October 1999), 158.8 (December 1999), 96.4 (February 2000), 400.7 (April 2000), 215.6 (October 2000) and 136.4 (December 2000) were observed. Abiotic factors may favour the development of the species of the food chain that sustain the organisms in the diet of 'tucunaré', but in this case, there was no correlation (P > 0.05) between the values of prevalence, mean intensity and mean abundance with the rainfall and water quality. At the same time, these organisms may constitute the intermediate hosts of cestodes. The time-course between the fish species development and the parasitosis manifestation in the definitive host can explain the lack of correlation between the parasitological indexes and abiotic factors. The predation on small fishes and cannibalism described for 'tucunaré' might explain the high values of prevalence and intensity of infection. The results are also related to the exotic condition of the host in the reservoir. PMID:19347164

[Determinants of food and nutrition insecurity: a study conducted in Low-budget Restaurants in Belo Horizonte in the state of Minas Gerais, Brazil].  

PubMed

The scope of this study is to evaluate the condition of household food and nutrition (in)security (IAN) of the users of low-budget restaurants in Belo Horizonte (BH). This is an analytical cross-sectional study carried out on all low-budget restaurants and cafeteria in BH with a sample of 1613 users. The IAN was assessed using the Brazilian Food Insecurity Scale and cross-checked with the socioeconomic profile of the users. The Chisquare and Mann-Whitney tests were applied. All p-value < 0.25 variables were included in the multivariate analysis. The groups most exposed to IAN among users of low-budget restaurants are those with a lower socioeconomic level and per capita income class and those with a large number of residents in the household. Also affected are those who admit to having different kinds of wants and needs, and those for whom price and living alone are the main reasons for frequenting low-budget restaurants. The factors affecting the IAN are varied and multifactorial, thus representing a major challenge for public policy makers and for those who live directly with these dietary restrictions. The low-budget restaurants serve as a strategy for promoting healthy eating habits. PMID:24897225

The aim of this study was to understand the current epidemiology of rickettsial diseases in two rickettsial-endemic regions in Brazil. In the municipalities of Pingo D'Agua and Santa Cruz do Escalvado, among serum samples obtained from horses and dogs, reactivity by immunofluorescent assay against spotted fever group rickettsiae was verified. In some serum samples from opossums (Didelphis aurita) captured in Santa Cruz do Escalvado, serologic response against rickettsiae was also verified. Polymerase chain reaction identified rickettsiae only in ticks and fleas obtained in Santa Cruz do Escalvado. Rickettsiae in samples had 100% sequence homology with Rickettsia felis. These results highlight the importance of marsupials in maintenance of the sylvatic cycle of rickettsial disease and potential integration with the domestic cycle. Our data also support the importance of horses and dogs as sentinels in monitoring circulation of rickettsiae in an urban area.

Geoquímica orgánica de los carbones de fila maestra, estado anzoátegui, Venezuela  

NASA Astrophysics Data System (ADS)

The vertical and lateral variability of organic geochemical parameters was established for the Seam 4 of the Fila Maestra coal deposit (Quebradon Formation, Oligocene-Early Miocene age) through the study of coals and carbonaceous shales collected in different outcrops of the coal seam. Chemical and physical analysis included moisture and ash contents, maceral groups, vitrinite reflectance, total carbon, bitumen and its fractions, as well as characterization of saturated hydrocarbons by gas chromatography ( n-alkane distributions and {pristane}/{phytane} ratios). A production sample, representative of the Seam 4, was further analyzed for S, Cl, C, H, O and its calorific value determined. The data collected allowed us to classify these samples as high-volatile bituminous coals, types B and C, according to ASTM classification. The results of the analysis showed little vertical or lateral variation in the properties studied. A gradual increase in ash content in the westward direction, together with a thinning of the coal seam, suggest a greater proximity of the basin border in this direction. High values in {pristane}/{phytane} ratio (4-7), predominance of heavy alkanes and high contents in vitrinites clearly indicates that primigenic organic matter was essentially continental in character. However, the bimodal n-alkane distribution, together with a nigh sulfur (2.7%) and chlorine (0.12%) contents suggest a marine-influenced environment. In consequence, it is proposed that these coals were formed in a transitional environment, as salt-marshs in coastal lagoons or in low deltaic plains. These results are in agreement with the stratigraphic analysis of the sedimentary unit.

This paper investigated metal contamination in muscle tissue of the grouper (Epinephelus coioides) in the vicinity of a single buoy mooring (SBM3) at the Sultanate of Oman. The fish samples were analyzed for cadmium (Cd), copper (Cu), lead (Pb) and vanadium (V). The mean concentrations of Cd, Cu, Pb and V in the fish samples were 0.05 ± 0.004, 0.34 ± 0.013, 0.20 ± 0.018 and 0.03 ± 0.006 mg/kg, respectively. The results were compared with the corresponding permissible concentration limits according to the Sultanate of Oman (0.05, 3.28, 0.3 and 1.4 mg/kg for Cd, Cu, Pb and V, respectively) and the European Commission (0.05 mg/kg for Cd and 0.3 mg/kg for Pb). It was found that none of the overall mean metal concentrations exceeded the corresponding Omani legislation or European Commission limits. However, the overall mean concentration of Cd was identical to the maximum permissible limit of 0.05 mg/kg that has been established by both Commissions, and the limits were exceeded for mean Cd levels in fish at two of the six sampling stations at SBM3. In general, this study indicated that the fishes at SBM3 were not highly contaminated with these metals. PMID:24145924

Factors influencing tropical island freshwater fishes:Species, status, and management implications in puerto rico [Factores que influencian a los peces tropicales de agua dulce: Especies, estado actual e implicaciones para el manejo en Puerto Rico  

USGS Publications Warehouse

Anthropogenic effects including river regulation, watershed development, contamination, and fish introductions have substantially affected the majority of freshwater habitats in Europe and North America. This pattern of resource development and degradation is widespread in the tropics, and often little is known about the resources before they are lost. This article describes the freshwater resources of Puerto Rico and identifies factors that threaten conservation of native fishes. The fishes found in freshwater habitats of Puerto Rico represent a moderately diverse assemblage composed of 14 orders, 29 families, and 82 species. There are fewer than 10 species of native peripherally-freshwater fish that require a link to marine systems. Introductions of nonindigenous species have greatly expanded fish diversity in freshwater systems, and native estuarine and marine species (18 families) also commonly enter lowland rivers and brackish lagoons. Environmental alterations, including land use and development, stream channelization, pollution, and the impoundment of rivers, combined with nonnative species introductions threaten the health and sustainability of aquatic resources in Puerto Rico. Six principal areas for attention that are important influences on the current and future status of the freshwater fish resources of Puerto Rico are identified and discussed.

2 cases of acute dermatitis caused by butterfly Hylesia metabus in an area that so far has not been considered as endemic for this species were presented. The dermatitis observed in these individuals may be described as very circumscribed, pruriginous, erythematous generalized protruding papules that may be compared with urticaria, and with a variable degree oedema. Monomorphic eruption consisting in small hard papules crowned by a little vesicle was also present. The lesions of these 2 patients evolved with intensely pruriginous papules for a week and after that they healed without dermatological sequelae. PMID:10349447

A preliminary combined geochemical and rock-magnetic study of tailings of non-magnetic ores from Tlalpujahua-El Oro mining districts, Michoacán and Estado de México States  

NASA Astrophysics Data System (ADS)

Mining activities in Mexico have been continuously developed since 1550. Since then several thousands of million tons of waste produced as a result of the mining activity have been accumulated and scattered throughout the territory. These wastes can contain minerals with potentially toxic elements (PTEs) such as Cr, As, Cd, Cu, Pb, Zn, which show a distribution and mobility in the environment according to the chemical species in which are hosted. The Tlalpujahua - El Oro mining district (TOMD) concentrates an impressive number of mines and historical tailings. Due to their in-slope hydrographic position, the mining activities increase the risk of generating anthropogenic effluent that could contribute with a certain amount of mine-water with high contents of PTEs. Although magnetic methods have been widely applied to pollution studies of regions with high anthropogenic impact, its application to tailings is scarce in spite of the several studies that document the environmental effects as a result of the mining waste. We present the results obtained by combined geochemical and rock-magnetic studies in these tailings. Similarly to the traditional EPTs vs SiO2 diagrams, EPTs vs Fe show good linear (inverse) correlation with most of these health-risk elements. Fe concentrations determined magnetically from room-temperature susceptibility measurements agrees with those obtained by traditionally geochemical methods.

A sequel to the work of systematic surveying the mycobiota of Lantana camara, aimed at finding potential biocontrol agents, was carried out during 1995-1996 covering part of its centre of origin in Brazil (state of Minas Gerais). Fifty-eight sampling sites, representing the four main climatic types in the state of Minas Gerais, were surveyed. Additional ad hoc collections were made in the states of Bahia, Espírito Santo, Parana, Rio de Janeiro and São Paulo. Fifteen fungal species were recorded in association with L. camara including the previously undescribed species Phomopsis lantanae-glutinosae sp. nov. Five fungi are also newly recorded on this host in Brazil: Cercospora lantanicola, Corynespora cassiicola, Meliola ambigua, Mycovellosiella lantaniphila and Phornopsis lantanae. The following fungi, previously recorded on L. camara in Brazil, are recorded here for the first time in Minas Gerais: Dendryphielia aspera, Micropustulomyces mucilaginosus, Mycovellosiella lantanae, Pseudocercospora guianensis and Puccinia lantanae.

We studied the yeast communities associated with fruits, mushrooms, tree exudates, and flies of the genus Drosophila, in two Atlantic Rain Forest fragments in state of Minas Gerais, Brazil. A total of 456 samples were collected from Rio Doce State Park and 142 from Ecological Station of Universidade Federal de Minas Gerais. From these samples, 608 yeast isolates were obtained, belonging to 71 different species. Among the yeasts isolated from Rio Doce State Park, 17 isolates were recovered from fruits, 12 from mushrooms, 13 from tree exudates, and 299 from Drosophila spp. In the Ecological Station of Universidade Federal de Minas Gerais, 24 isolates were recovered from fruits and 243 from Drosophila spp. Distinct communities of yeast were observed in Drosophila flies, fruits, mushrooms and tree exudates. The highest number of yeast species was recovered from Drosophila flies suggesting that flies are the natural vectors of these microorganisms.

Dombrock genotyping in Brazilian blood donors reveals different regional frequencies of the HY allele  

PubMed Central

Background Dombrock blood group system genotyping has revealed various rearrangements of the Dombrock gene and identified new variant alleles in Brazil (i.e., DO*A-SH, DO*A-WL and DO*B-WL). Because of the high heterogeneity of the Brazilian population, interregional differences are expected during the investigation of Dombrock genotypes. Objective The present study aims to determine the frequencies of Dombrock genotypes in blood donors from Minas Gerais and compare the frequencies of the HY and JO alleles to those of another population in Brazil. Methods The frequencies of the DO alleles in Minas Gerais, a southeastern state of Brazil, were determined from the genotyping of 270 blood donors. Genotyping involved polymerase chain reaction and restriction fragment length polymorphism analysis to identify the 323G>T, 350C>T, 793A>G, and 898C>G mutations, which are related to the HY, JO, DO*A/DO*B, and DO*A-WL/DO*B-WL alleles, respectively. Moreover, the frequencies of rare HY and JO alleles were statistically compared using the chi-square test with data from another Brazilian region. Results The HY allele frequency in Minas Gerais (2.4%) was almost twice that of the JO allele (1.5%). The frequency of the HY allele was significantly higher (p-value = 0.001) than that in another Brazilian population and includes a rare homozygous donor with the Hy- phenotype. In addition, the DO*A-WL and DO*B-WL alleles, which were first identified in Brazil, were found in the state of Minas Gerais. Conclusions The data confirm that the frequencies of DO alleles differ between regions in Brazil. The population of Minas Gerais could be targeted in a screening strategy to identify the Hy- phenotype in order to develop a rare blood bank.

[The Meninos do Rio Program: lifeworld, adolescence, and health risks].  

PubMed

This study focuses on health risks among teenagers from two towns in the Sao Francisco River Valley (Ibiai and Morada Nova) and slums in Morro das Pedras, Belo Horizonte, Minas Gerais State, Brazil. The study discusses teaching and extracurricular activities by the Federal University in Minas Gerais in these localities, aimed at promoting health in adolescence. The authors use the Habermas communicative action theory as the main theoretical and methodological approach. The research adopted a qualitative and quantitative methodology, including dynamic observation, focus groups, interviews, and questionnaires answered by high school students. Sexuality, work, and violence were the main themes and were associated with numerous health risks. Work in the 10-to-14-year-old group was associated with nearly all types of health risks. The authors analyze the relations between context and adolescent behavior using the Habermasian concept of lifeworld colonization. PMID:15692636

Samplings were carried out yielding six species of three Chaetonotidae genera: Aspidiophorus cf. pleustonicus, Ichthydium cf. chaetiferum, Chaetonotus acanthocephalus, Chaetonotus heideri, Chaetonotus cf. succinctus, Chaetonotus sp., and also an undescribed species belonging to the genus Redudasys (incertae sedis): this is the first finding of specimens of Redudasys outside of original type locality. These preliminary observations suggest that the knowledge of the biodiversity of Gastrotricha in the Minas Gerais State, as well as in the whole Brazil, will certainly increase as further investigations are undertaken, and that freshwater Macrodasyida may be more common than previously thought.

Intermediate hosts of Schistosoma mansoni in Brazil.  

PubMed

The Brazilian planorbidical chart is slowly but progressively been increased by new data. Distribution of vector species of Schistosoma mansoni, according to Paraense, 1986, may be thus resumed: Biomphalaria glabrata--delimited by parallels 13 and 21 degrees S and meridians 39 and 45 degrees W, area of greater dominance (Southeast Bahia, oriental hal of Minas Gerais and Espírito Santo). It is observed along the coast line of the states of Sergipe, Alagoas, Pernambuco, Paraiba and Rio Grande do Norte. Starting from there, it is found towards the southwest, in the direction to the São Francisco River and South-Center of Minas Gerais. Isolated population may be observed in other states. Its presence is probably, associated to the transmission of schistosomiasis in all areas where it occurs. B. tenagophila--extends it self through a wide strip of coast-line from the South of Bahia (17 degrees 45'S; 39 degrees 15'W), RS (33 degrees 41'S, 53 degrees 27'W). In São Paulo and Rio Grande do Sul states it is found further inland. It is important in schistosomiasis transmission in the Paraiba valley (SP). Isolated populations are observed in the Federal District and Minas Gerais state. B. straminea--better adapter species to climatic variation, having a more dense distribution in the northeast (41 degrees W and 110 degrees S), south of Bahia and northeast of Minas Gerais (150 and 180 degrees S, 400 and 440 degrees W). It is less susceptible than the B. glabrata, being however, the most important responsible for the transmission of S. mansoni in the northeast, chiefly in the northeastern dry area, where it is almost the only transmissive species.

The present investigation deals with the uptake of As(III) and As(V) ions from aqueous solution by activated alumina and a new laboratory-prepared sorbent—iron oxide impregnated activated alumina. Iron oxide impregnation onto activated alu- mina significantly increased the percent arsenic removal and adsorption capacity for As(III) and As(V) ions. The maximum As(III) and As(V) removals were 96.8% and 98.4%, respectively, by

Factors associated with the catastrophic decline of a cloudforest frog fauna in Guatemala.  

PubMed

Comparison of recent and historical surveys of frog populations in cloudforest habitat in Sierra de las Minas, Guatemala, indicated population declines and local extirpation of several species. Pathological exams of diseased tadpoles indicated infection by amphibian chytridiomycosis. The local habitat has been severely altered by recent establishment of large-scale leatherleaf fern production. Analysis of water chemistry at our study site suggested increased nitrogenation associated with the leatherleaf industry. PMID:17354411

A new instrument for high-resolution in situ assessment of Young's modulus in shallow cohesive sediments  

NASA Astrophysics Data System (ADS)

This paper describes a new, miniature, instrumented flat dilatometer (mIDMT) designed to assess variations in nearly continuous compressive stress-strain behaviour with depth in shallow cohesive sediments. The instrument was tested both in situ in the Bay of Fundy, Nova Scotia, Canada, and in cored samples from Willapa Bay, Washington, USA. Comparisons between probe and laboratory uniaxial assessments for other elastic materials—gelatine and foam rubber specifically—show strong agreement over the range of strains induced in the experiments. Observed values of Young's modulus ( E) for the gelatine and ethylene-vinyl acetate foam ranged from 6-343 kPa. Sediment stress-strain curves were distinctly linear for the overconsolidated fine-grained sediments of the Minas Basin, and values of E were found to increase with depth from near zero to 500-1,300 kPa at 20 cm depth. At the Willapa site, the sandy tidal flat sediments also behave elastically but E tended to increase more strongly with depth than for sediments from the Minas Basin. Young's modulus was inversely correlated to porosity at all sites tested, and linearly related to shear strength in the Minas Basin. The newly designed instrument has much finer resolution than for other, similar methods of determining E in situ, and it provides data at a resolution sufficient to assess small-scale processes such as gas bubble growth and infaunal locomotion, for which elastic constants are needed for modelling and prediction.

Mitochondrial genetic variability of Didelphis albiventris (Didelphimorphia, Didelphidae) in Brazilian localities  

PubMed Central

Didelphis albiventris is a well-known and common marsupial. Due to its high adaptability, this very widespread generalist species occurs under various environmental conditions, this even including protected regions and disturbed urban areas. We studied a 653 bp fragment of cytochrome oxidase c (COI) from 93 biological samples from seven Brazilian localities, with linear distances ranging between 58 and about 1800 km to analyze the effects of geographic distances on variability and genetic differentiation. The haplotype network presented nine haplotypes and two genetic clusters compatible with the two most distant geographic areas of the states of Minas Gerais, in the southeast, and Rio Grande do Sul, in the extreme south. As each cluster was characterized by low nucleotide and high haplotype diversities, their populations were obviously composed of closely related haplotypes. Surprisingly, moderate to high FST differentiation values and a very weak phylogeographic signal characterizes interpopulation comparisons within Minas Gerais interdemes, these being correlated with the presence of privative haplotypes. On a large rgeographic scale, a comparison between demes from Minas Gerais and Rio Grande do Sul presented high FST values and a robust phylogeographic pattern. This unexpected scenario implies that mtDNA gene flow was insufficient to maintain population cohesion, reflected by the observed high differentiation.

The linearity of these lakes suggests that they could have, in the past, belonged to the same drainage system, that would have been disconnected throughout the evolution of the Vereda system. The objective of this research is with the help of the GPR and using 100 MHz antennaes to obtain radargram images that could assist in the interpretation of the structures occurring at the bottom of these lakes. It is possible do identify on the radargrams reflectors that can be correlated with depositional system. These reflectore have the concave form. The results of these radargrames indicate great conformity between the concave form of the sediments and that of the bottom of the lake, allowing to assume that this deposition has been occurring since a long time ago. Therefore, if there was a connection between the study lake and those located in its proximity it has occurred a long time, before the deposition of the sedimentary sequences had been deposited. The thickness of the sediments, that varies since 2m until 5m, indicates that or either this deposition was either a very rapid one so that could generate a fast deposition, or it has been taking place during a considerable geologic long time.; Data acquisitiont;

Geotourism in the "Estrada Real", Brazil  

NASA Astrophysics Data System (ADS)

Many natural landscapes are preserved throughout the World due to their cultural and historical values as well as for their environmental importance. The Way of Saint James of Compostela (Camino de Santiago de Compostela), located in Europe, is a well known example of this. It was the inspiration source for the development of a tourist route in the Brazilian States of Minas Gerais, Sao Paulo and Rio de Janeiro, although it has no pilgrimage connotation. The Estrada Real (literally translated as the Royal Route) is made of a series of roads or routes that were formerly used by the Portuguese colonizers to control the flow of gold, silver, diamonds and other precious stones and minerals. The tourist activities, particularly in the State of Minas Gerais, are experiencing an accelerated growth, benefiting the local and traditional communities economically. The existence of various geomorphological and geological sites in the Estrada Real has also favored the increase of the ecotourism and the Brazilian incipient geotourism. However, the uncontrolled touristic activities can damage the natural environment and some historical heritage sites. This research basically consisted in a preliminary identification of important geomorphosites such as caves and mountains that need to be protected for a rational and sustainable use. Out of the 4,632 known Brazilian caves, approximately 1,655 caves developed in limestone, dolomite, quartzite and granite are located in the State of Minas Gerais. For this reason, the authors strongly recommend that studies on the importance of such geomorphosites should take place in the municipalities of the Estrada Real in order to guide the regional development of tourism and sustainable development. Keywords: ecotourism, Estrada Real, sustainability.

Control of Listeria monocytogenes growth in soft cheeses by bacteriophage P100.  

PubMed

The purpose of this study was to determine the effect of bacteriophage P100 on strains of Listeria monocytogenes in artificially inoculated soft cheeses. A mix of L. monocytogenes 1/2a and Scott A was inoculated in Minas Frescal and Coalho cheeses (approximately 10(5) cfu/g) with the bacteriophage added thereafter (8.3 × 10(7) PFU/g). Samples were analyzed immediately, and then stored at 10 °C for seven days. At time zero, 30 min post-infection, the bacteriophage P100 reduced L. monocytogenes counts by 2.3 log units in Minas Frescal cheese and by 2.1 log units in Coalho cheese, compared to controls without bacteriophage. However, in samples stored under refrigeration for seven days, the bacteriophage P100 was only weakly antilisterial, with the lowest decimal reduction (DR) for the cheeses: 1.0 log unit for Minas Frescal and 0.8 log units for Coalho cheese. The treatment produced a statistically significant decrease in the counts of viable cells (p < 0.05) and in all assays performed, we observed an increase of approximately one log cycle in the number of viable cells of L. monocytogenes in the samples under refrigeration for seven days. Moreover, a smaller effect of phages was observed. These results, along with other published data, indicate that the effectiveness of the phage treatment depends on the initial concentration of L. monocytogenes, and that a high concentration of phages per unit area is required to ensure sustained inactivation of target pathogens on food surfaces.

Determination of the Order of Passes of AN Austenitic Weld by Optimization of AN Inversion Process of Ultrasound Data

Multipass welds made in austenitic stainless steel, in the primary circuit of nuclear power plants with pressurized water reactors, are characterized by an anisotropic and heterogeneous structure that disturbs the ultrasonic propagation and challenge the ultrasonic non-destructive testing. The simulation in this type of structure is now possible thanks to the MINA code which allows the grain orientation modeling taking into account the welding process, and the ATHENA code to exactly simulate the ultrasonic propagation. We propose studying the case where the order of the passes is unknown to estimate the possibility of reconstructing this important parameter by ultrasound measures. The first results are presented.

Abstract A typing procedure based on polymorphism of the coagulase gene (coa) was used to discriminate Staphylococcus aureus isolated from Minas Gerais dairy cows with mastitis. Amplification of the gene from the 64 S. aureus isolates produced 27 different polymerase chain reaction (PCR) products; 60 isolates showed only 1 amplicon, and 4 showed 2 amplicons. The isolates were grouped into 49 types by analyzing the restriction fragment length polymorphism (RFLP) of the coa gene; the 10 most common types accounted for 39% of the isolates. The results demonstrate that many variants of the coa gene are present in the studied region, although only a few predominate.

The behavior of dissolved uranium in groundwaters of the Morro do Ferro thorium deposit, Brazil  

NASA Astrophysics Data System (ADS)

Groundwater samples were collected for several months in boreholes drilled at Morro do Ferro, a thorium and rare earth deposit located on the Poços de Caldas Plateau, Minas Gerais State, Brazil. An aquifer system has developed in the weathered mantle due to in situ intense alteration. The weathered zone includes a thick argillaceous laterite greater than 100 m thick. The U content and 324U/ 238U activity ratio were measured in the groundwater samples and in spoil samples of a borehole drilled in the ore body. Some possible mechanisms related to the mobilization of uranium are considered such as complexation with humic substances and adsorption by clays.

Geology and tectonic history of Southeastern Luzon, Philippines  

NASA Astrophysics Data System (ADS)

Southeastern Luzon belongs to the eastern Philippine Mobile Belt. Geological and structural studies revealed that it could be divided into three major structural units limited by two subparallel NW-SE trending left-lateral strike-slip faults: the Hilawan Fault in the NE and the Minas Fault in the SW. The North-central Catanduanes Structural Unit (NCSU) is characterized by a Middle to early Late Cretaceous volcanic arc sequence unconformably overlain by a Middle to Late Eocene volcanic arc sequence followed by Early Oligocene intrusives. The Median Structural Unit (MSU), limited from the NCSU by the Hilawan Fault, is underlain by a Late Cretaceous volcanic arc sequence followed by two distinct chaotic sequences from the end of Cretaceous-Paleocene and latest Middle Eocene-earliest Late Eocene. It is limited to the southwest by the Minas Fault. The Western Caramoan Structural Unit (WCSU), pre-Late Cretaceous ophiolitic suite unconformably overlain by Late Cretaceous volcanic arc sequence and Middle Eocene limestones are exposed. These structural units are overlain by carbonate and detrital sequence from the Late Oligocene to Pliocene. Constrained by angular unconformities and deposition of olistostromes, polyphase left-lateral strike-slip faulting was recorded since the end of Cretaceous up to the limit of Early-Late Oligocene. These faults probably represent the traces of a Proto-Philippine Fault System in Southeastern Luzon.

[The use of metaphors to express toothache: a study in the field of the anthropology of health].  

PubMed

This research was conducted with patients who sought emergency care at a Comprehensive Primary Care Clinic (CIAP IV) at the Dental School of Minas Gerais Federal University and at the Dental Center of a medium-sized city in the state of Minas Gerais. The scope of this article is to identify how the social representations of this issue are generated through the metaphors used by patients to express toothache. A total of 35 individuals of both genders who sought emergency care for toothache participated in the study. Content theme analysis was used. Social representations of toothache are generated as people resort to their life experiences to find words to express the problem. Prior sensations and feelings, and even imaginary situations, generate metaphors to attempt to explain the suffering. Toothache is often compared with the worst feelings ever experienced by individuals. Toothache represents great suffering for people seeking emergency dental care. This fact may help to develop further public oral health policies, bearing in mind that a socially deprived population is more often afflicted by toothache. PMID:24897492

The Tropical Biominer Project: mining old sources for new drugs.  

PubMed

The Tropical Biominer Project is a recent initiative from the Federal University of Minas Gerais (UFMG) and the Oswaldo Cruz foundation, with the participation of the Biominas Foundation (Belo Horizonte, Minas Gerais, Brazil) and the start-up Homologix. The main objective of the project is to build a new resource for the chemogenomics research, on chemical compounds, with a strong emphasis on natural molecules. Adopted technologies include the search of information from structured, semi-structured, and non-structured documents (the last two from the web) and datamining tools in order to gather information from different sources. The database is the support for developing applications to find new potential treatments for parasitic infections by using virtual screening tools. We present here the midpoint of the project: the conception and implementation of the Tropical Biominer Database. This is a Federated Database designed to store data from different resources. Connected to the database, a web crawler is able to gather information from distinct, patented web sites and store them after automatic classification using datamining tools. Finally, we demonstrate the interest of the approach, by formulating new hypotheses on specific targets of a natural compound, violacein, using inferences from a Virtual Screening procedure.

Naturally acquired visceral leishmaniasis in non-human primates in Brazil.  

PubMed

Visceral leishmaniasis (VL) is a chronic and often fatal protozoal disease that is endemic in Belo Horizonte (State of Minas Gerais, Brazil). Leishmania sp. is an intracellular obligatory parasite of macrophages that can naturally infect several mammalian species. Non-human primates (NHP) have been used as experimental models for infection with Leishmania of the donovani complex. The present report describes a case of visceral leishmaniasis in a black-fronted titi. Among 41 primates kept in captivity in a zoo in Belo Horizonte (State of Minas Gerais, Brazil), one animal, a black-fronted titi (Callicebus nigrifrons), was positive for Leishmania chagasi infection by PCR and immunohistochemistry, and developed a fatal disease with clinical signs and lesions compatible with VL.

New records and human parasitism by Ornithodoros mimon (Acari: Argasidae) in Brazil.  

PubMed

The bat tick Ornithodoros mimon Kohls, Clifford & Jones is currently known by only few reports in Bolivia, Uruguay, Argentina, and the state of São Paulo in southeastern Brazil. Here, we expand the distribution of O. mimon in Brazil to the states of Minas Gerais (southeastern region), Goiás (central-western), Pernambuco, and Rio Grande do Norte (northeastern). Ticks were collected on human dwellings, where there had been repeated complains of tick bites on persons during the night. Tick bites were generally followed by intense inflammatory reactions that lasted for several weeks at the bite site. Bats and opossums were reported to inhabit the attic of the infested houses. In addition, a free-ranging opossum (Didelphis albiventris Lund) trapped in Rio Grande do Norte was found infested by argasid larvae. Based on morphological and/or molecular analysis, all ticks were identified as O. mimon. From one of the sites (Tiradentes, state of Minas Gerais), 20 field-collected nymphs were tested by a battery of polymerase chain reaction protocols targeting tick-borne microorganisms of the genera Babesia, Hepatozoon, Rickettsia, Borrelia, Anaplasma, Ehrlichia, and Coxiella; no tick specimen was found infected by any of these microorganism genera. The current study expands northwards the distribution of O. mimon, which has been shown to be very harmful to humans because of the intense inflammatory response that usually occurs after tick bites.

An improved unified network protocol framework for large-scale wireless sensor networks  

NASA Astrophysics Data System (ADS)

Rapid technological advances in wireless communication have made it possible for networking sensor devices. Given the low computation and battery power capacities of these sensor nodes, the key design factors of network protocols are self-configuring, energy-efficient, adaptive, and scalable. We presented the multi-hop infrastructure network architecture (MINA) for a wireless sensor network consisting of a few hundred sensors that communicate data to a base station (BS). We designed a Unified Network Protocol Framework for MINA that encompasses network organization, medium access control (MAC) and routing protocols. In this paper, we improve it by adaptively varying transmission range to maintain network connectivity. It is a derivative-free optimization algorithm. The BS periodically evaluates the objective function, chooses the appropriate transmission range and broadcasts it to the sensor nodes that then update the transmission range. The advantages are: (i) Avoids the disconnectivity; (ii) Maximizes the number of nodes that can be connected to the BS, (iii) Minimizes the energyxdelay metric and (iv) Avoids the "hot-spot" nodes in the network. The performance in terms of delay, throughput, energy consumption and network lifetimes, is studied in detail using discrete-event simulation compared with other protocol. The results show that it is energy efficient in a large scale network.

Polytypic and polymorphic cytogenetic variations in the widespread anuran Physalaemus cuvieri (Anura, Leiuperidae) with emphasis on nucleolar organizing regions.  

PubMed

We investigated the NOR distribution in ten populations of Physalaemus cuvieri from different regions of Brazil and Argentina. A high variability in NOR pattern was observed and provided a useful tool in grouping several populations. The specimens from the state of Tocantins, northern Brazil, could easily be distinguished from all the other analyzed populations, since its karyotype presented NORs in the chromosome pairs 1,3,4 and 10 (and sometimes also in chromosome 5), and several pericentromeric C-bands. A NOR-site in chromosome 9 characterized three populations from the northeastern region of Brazil. Interestingly, the P. cuvieri populations located in opposite extremes of the geographic distribution had, as a fixed condition, the presence of NORs in 8q int and llp. Besides interpopulational divergences, intrapopulational variability was observed in the number of NORs, except for populations from the states of Bahia and Minas Gerais, which are boundary states respectively in the northeastern and southeastern regions of Brazil. In relation to NOR size, interindividual variations occurred in all Brazilian and Argentinean populations. Additionally, intraindividual variability in NOR size was detected in specimens from Minas Gerais. The data presented herein revealed substantial geographic polytypic variation in P. cuvieri and indicated that a taxonomic reexamination of this species is necessary. PMID:19621135

Hymenopteran parasitoids associated with frugivorous larvae in a Brazilian caatinga-cerrado ecotone.  

PubMed

The purpose of this study was to investigate native species of parasitoids of frugivorous larvae and their associations with host plants in commercial guava orchards and in typical native dry forests of a caatinga-cerrado ecotone in the State of Minas Gerais, Brazil. Nine species of parasitoids were associated with larvae of Anastrepha (Tephritidae) and Neosilba (Lonchaeidae) in fruit of Psidium guajava L. (Myrtaceae), Ziziphus joazeiro Mart. (Rhamnaceae), Spondias tuberosa Arruda (Anacardiaceae), Spondias dulcis Forst. (Anacardiaceae), Syzygium cumini (L.) Skeels (Myrtaceae), and Randia armata (Sw.) DC. (Rubiaceae). Doryctobracon areolatus was the most abundant species, obtained from puparia of Anastrepha zenildae, An. sororcula, An. fraterculus, An. obliqua, and An. turpiniae. This is the first report of Asobara obliqua in Brazil and of As. anastrephae and Tropideucoila weldi in dry forests of Minas Gerais State. The number of species of parasitoids was higher in areas with greater diversity of cultivated species and lower pesticide use. The forest fragments adjacent to the orchards served as shelter for parasitoids of frugivorous larvae. PMID:22506994

Genetic characterization of cassava (Manihot esculenta) landraces in Brazil assessed with simple sequence repeats  

PubMed Central

Based on nine microsatellite loci, the aim of this study was to appraise the genetic diversity of 42 cassava (Manihot esculenta) landraces from selected regions in Brazil, and examine how this variety is distributed according to origin in several municipalities in the states of Minas Gerais, São Paulo, Mato Grosso do Sul, Amazonas and Mato Grosso. High diversity values were found among the five above-mentioned regions, with 3.3 alleles per locus on an average, a high percentage of polymorphic loci varying from 88.8% to 100%, an average of 0.265 for observed heterozygosity and 0.570 for gene diversity. Most genetic diversity was concentrated within the regions themselves (HS = 0.52). Cluster analysis and principal component based scatter plotting showed greater similarity among landraces from São Paulo, Mato Grosso do Sul and Amazonas, whereas those from Minas Gerais were clustered into a sub-group within this group. The plants from Mato Grosso, mostly collected in the municipality of General Carneiro, provided the highest differentiation. The migration of human populations is one among the possible reasons for this closer resemblance or greater disparity among plants from the various regions.

Flocculation and sediment deposition in a hypertidal creek  

NASA Astrophysics Data System (ADS)

In the hypertidal Bay of Fundy, environmental impacts in response to commercial-scale tidal power development remain to be fully understood. The extraction of tidal energy may impact sediment dynamics in far-field environments, such as the intertidal zone, through potential alterations to tidal amplitude in the Minas Basin. Tidal conditions (e.g. current velocity, turbulence, suspended sediment concentration) were monitored in a sheltered salt marsh creek over 18 tidal cycles in various stages of the spring-neap cycle. Samples of deposited and suspended sediments were collected and analyzed for grain size using a Beckman Coulter Multisizer III. Results suggest that the flocculated component of both deposited and suspended sediment is consistently high over a wide range of tidal conditions. A routinely high incoming concentration of highly-flocculated material results in large amounts of sediment deposition in tidal creeks in response to individual tidal cycles. Resuspension and removal of newly deposited material is shown to vary with over-marsh, bankfull and channel-restricted tides. Disruption of the tidal regime due to a reduction in Minas Basin tidal amplitude may lessen the cumulative export capacity of tidal channels over time, potentially leading to gradual infilling of tidal creeks. The long-term effects of tidal power development on intertidal areas are generally unknown.

Contrasting compositions of amphiboles in two Neoproterozoic Banded iron formations of Uruguay  

NASA Astrophysics Data System (ADS)

Two occurrences of iron formations from the Precambrian of Uruguay were mineralogically and petrographically investigated. One of these deposits, located to the north of Minas City is associated with a low metamorphic grade Ediacaran succession (Minas Formation - Arroyo del Soldado Group) where glacial influence has been suggested. Fine grained quartz, Fe-rich amphibole (grunerite), magnetite porphyroblasts and hematite laths characterize these BIFs. Although an earlier increase of ferrous iron in solution in deeper water through the glacial episode is a probable factor, the identification of volcaniclastic acid rocks in the sequence indicates that Fe-fluids of volcanic origin played also an important role. A Rapitan type for this deposit is indicated by geological features and age constrains. The other analyzed deposit is associated with a highly deformed low- to medium- grade metamorphic supracrustal succession (Zanja del Tigre Formation) occurring as tectonic slices in a pre- Neoproterozoic basement. The age of this unit is not well constrained but field evidences and indications of glacigenic deposits indicate Cryogenian or Tonian age. This iron formation consists of about 2-5 cm thick layers, composed of alternating bands rich in quartz, magnetite and hematite, carbonate (calcite) and Mg-amphibole (cummingtonite). The difference found in the mineral chemistry of the amphiboles between both deposits suggests that, in the latter deposit, metamorphic changes in the paragenesis were associated with higher oxygen fugacity.
