[Lead poisoning: Zinc protoporphyrin in blood of children from Santo Amaro da Purificação, Bahia, Brazil].  

PubMed

A cross-sectional epidemiological study has investigated lead poisoning among all the 101 children aged 1 to 5 years, living at less then 500 m from a lead smelter which has been operating since 1960 in Santo Amaro da Purificação, State of Bahia, Brazil. Lead poisoning was evaluated by determining the concentrations of zinc protoporphyrin (ZPP) in whole blood. Results were compared with those obtained from 98 children of the same age range, in a nursery from Salvador, capital of the State of Bahia. In Santo Amaro, ZPP geometric mean was 65.5 mg/dl (geometric S.D. = 1.7), much higher, therefore, than the normal threshold of 30 microg/dl recommended by the CDC-USA. A child was excluded from statistical analyses because of very high ZPP level: 789 mg/dl. In Salvador, ZPP geometric mean was 31.0 mg/dl (geometric SD = 1.6). "Extremely elevated" ZPP levels (above 156 mg/dl) were observed in 8% of the children from Santo Amaro and in none (0%) of the children from Salvador, this statistical difference being highly significant. Anaemia was present among 35.0% of the children from Santo Amaro and among 25.5% of those from Salvador. One year-old children showed the highest levels of ZPP and anaemia. No marked statistical association was found between ZPP levels and anaemia. Lead contamination of this children population remained in a permanently high level during, at least, the period from 1980 to 1992. In December, 1993 the lead smelter has definitively ceased its industrial activities in Santo Amaro da Purificação. PMID:14688915

Specific Kinematic Evolution of the Santos Basin - Sao Paulo Plateau  

NASA Astrophysics Data System (ADS)

The Sao Paulo Plateau is a prominent marginal plateau in the Southern Brazilian margin, located at the boundary between the central segment and the austral segment of the South Atlantic Ocean. These two segments are in two different geodynamic contexts, since southern segment opens at the anomaly M7 (132 My according to Gradstein et al., 2004) whereas the central segment opens at the end of the evaporite deposit (Upper Aptian - Lower Albian: 112 Ma). The two segments are also in two different structural contexts, since the margins of the austral segment are considered as volcanic margins (Gladczenko et al., 1997, Gladczenko et al., 1998, Hinz et al., 1999, Bauer et al., 2000…), whereas the margins of the central segment as described as saliferous, non-volcanic margins (Butler, 1970, Leyden et al., 1972, 1976). Although many geophysical investigations were carried out on the Sao Paulo Plateau during the 1970's (more than 10 000 wells and several hundred thousands kilometres of seismic reflections profiles were acquired), its origin, history and evolution remained largely unknown. Since 40 years, a variety of structural and geodynamic models has been proposed to explain the different geological and geophysical observations. Some arguments (refraction data, magnetism) support the evidence that thickened oceanic crust underlies the Sao Paulo Plateau. Whereas some others (gravity modelling, seismic study, re-interpretation of refraction data, backstripping modelling, …) support the evidence of extremely stretched continental crust. At last, some authors (Gladczenko et al., 1998) suggested that the core of the Sao Paulo Plateau might be a micro-continent, in part covered by break-up extrusive material. Understanding the geological evolution of the Sao Paulo Plateau became more crucial since the giant oil field discovery (Tupi) in November 2007, in the Santos basin. We provide here a detailed kinematic model of this area. Following Moulin et al., (2007, Earth Science Reviews, submitted), we suggest that the area including the Paranà-Etendeka CFB's, the Santos Basin and the Sao Paulo Plateau, plays a role of "kinematic buffer" between the Austral and the Central segments of South Atlantic Ocean. At chron M4 and until Aptian, the Santos block seems to start to follow the general westward movement of the southern part of the South America. The northern and southern boundaries of the Santos Basin therefore were the place of intraplate deformations and became the locations of a "second-order intra-plate boundary" as defined by Olivet et al., (1984). This detailed kinematic model together with the interpretations of seismic industrial profiles seem to provide evidence of the existence of a continental microplate on the eastern part of Sao Paulo Plateau, wich is linked to Africa until the Aptian-Albian time. Then, break-up jumped eastward, closeto the Mocamedes area, leaving a very asymmetrical passive margins system. In this hypothesis, the central part of the Santos Basin seems to be made of thickened oceanic crust or exhumed mantle and, on both sides, of exhumed lower continental crust (the allochthonous continental slope of Aslanian et al., 2009); the eastern part represents the continental relic of Africa.

Santos Basin Geological Structures Mapped by Cross-gradient Method  

NASA Astrophysics Data System (ADS)

Introduction We mapped regional-scale geological structures localized in offshore zone Santos Basin, South-East Brazilian Coast. The region is dominated by transition zone from oceanic to continental crust. Our objective was to determine the imprint of deeper crustal structures from correlation between bathymetric, gravity and magnetic anomaly maps. The region is extensively studied for oil and gas deposits including large tectonic sub-salt traps. Our method is based on gradient directions and their magnitudes product. We calculate angular differences and cross-product and access correlation between properties and map structures. Theory and Method We used angular differences and cross-product to determine correlated region between bathymetric, free-air gravity and magnetic anomaly maps. This gradient based method focuses on borders of anomalies and uses its morphological properties to access correlation between their sources. We generated maps of angles and cross-product distribution to locate correlated regions. Regional scale potential fields maps of FA and MA are a reflection of the overlaying and overlapping effects of the adjacent structures. Our interest was in quantifying and characterizing the relation between shapes of magnetic anomalies and gravity anomalies. Results Resulting maps show strong correlation between bathymetry and gravity anomaly and bathymetry and magnetic anomaly for large strictures including Serra do Mar, shelf, continental slope and rise. All maps display the regional dominance of NE-SW geological structures alignment parallel to the shore. Special interest is presented by structures transgressing this tendency. Magnetic, gravity anomaly and bathymetry angles map show large correlated region over the shelf zone and smaller scale NE-SW banded structures over abyssal plane. From our interpretation the large band of inverse correlation adjacent to the shore is generated by the gravity effect of Serra do Mar. Disrupting structures including bathymetric anomaly generated by landslides responsible for smaller depth over continental rise has show strong inverse correlation with gravity anomaly and strong correlation with magnetic anomaly over continental rise. This indicates the influence of sedimentary deposits on deeper crustal structures. Methods and result are discussed.

Thermal subsidence of Santos and Sergipe-Alagoas Basins, Brazil - application to hydrocarbon exploration  

SciTech Connect

A uniform lithospheric extension model has been applied to the subsidence and thermal history of the Santos and Sergipe-Alagoas basins. Thermal subsidence curves were derived from more than 40 exploratory wells, complemented by seismic and gravity sections. In the Santo basin, the region landward of the hinge zone is dominated by Tertiary marine onlapping sediments. Seaward, rift (continental) and postrift (transitional and marine) sequences are present with predominance of the latter. Crustal thinning by 35% exists just east of the hinge zone and increases to 70% at the shelf break. Likewise, the hinge zone in the Sergipe-Alagoas basin overlies the largest gradient in crustal thinning, but unlike the Santos basin, rift-stage sediments dominate landward of this hinge zone. Seaward, the ratio of rift to postrift sediments is larger than in the Santos basin. Crustal thinning ranges from 20% to 60%, but this transition occurs over a short distance. Thermal and burial histories were used to estimate oil windows for potential source rocks in various parts of these basins. Maturation profiles are in good agreement with observed vitrinite reflectance and hydrocarbon maturity data. The areal distribution of maturation stages through time is variable and largely controlled by crustal thinning. Information on timing of hydrocarbon generation was applied to the prediction and evaluation of hydrocarbon accumulation.

Mangrove swamps of the Subaé and Paraguaçú tributary rivers of Todos os Santos Bay, Bahia, Brazil  

NASA Astrophysics Data System (ADS)

Different areas from the Todos os Santos Bay were monitored and the fate of heavy metals in these environments was determined. From 1982 to 1992, a significant worsening in the availability of heavy metals in the different sites of the Bay was observed. However, it must be emphasised that the comparison between the present results and those obtained from other works rests on a gap of at least three years. The determinations of heavy metal concentrations were based on the analysis of surface sediments of the different stations selected and the observed increase is probably due to the transport of the elements by tidal dynamics and upstream riverine transport of industrial effluents.

Cytherellid species (Ostracoda) and their significance to the Late Quaternary events in the Santos Basin, Brazil  

USGS Publications Warehouse

Four autochthonous cytherellid species (Cytherella serratula (BRADY, 1880), C. hermargentina WHATLEY et al. 1998, C. pleistocenica sp. nov. and C. santosensis sp. nov.) have been identified from two offshore cores (44 samples) within the Santos Basin. The distribution of these ostracodes is controlled by local hydrological conditions such as the temperature and, possibly, the oxygen minimum zone (OMZ). However, these factors cannot explain completely the species occurrence in the analysed cores, and relative sea level changes and productivity variation driven by climatic changes are proposed as additional explanations for the faunal distribution pattern. ??

Espirito Santo Virus: a New Birnavirus That Replicates in Insect Cells  

PubMed Central

Espirito Santo virus (ESV) is a newly discovered virus recovered as contamination in a sample of a virulent strain of dengue-2 virus (strain 44/2), which was recovered from a patient in the state of Espirito Santo, Brazil, and amplified in insect cells. ESV was found to be dependent upon coinfection with a virulent strain of dengue-2 virus and to replicate in C6/36 insect cells but not in mammalian Vero cells. A sequence of the genome has been produced by de novo assembly and was not found to match to any known viral sequence. An incomplete match to the nucleotide sequence of the RNA-dependent RNA polymerase from Drosophila X virus (DXV), another birnavirus, could be detected. Mass spectrometry analysis of ESV proteins found no matches in the protein data banks. However, peptides recovered by mass spectrometry corresponded to the de novo-assembled sequence by BLAST analysis. The composition and three-dimensional structure of ESV are presented, and its sequence is compared to those of other members of the birnavirus family. Although the virus was found to belong to the family Birnaviridae, biochemical and sequence information for ESV differed from that of DXV, the representative species of the genus Entomobirnavirus. Thus, significant differences underscore the uniqueness of this infectious agent, and its relationship to the coinfecting virus is discussed.

The dynamics of internal tidal waves in Todos Santos Bay, Baja California, during experiment FLOO-2007  

NASA Astrophysics Data System (ADS)

The aim of this work is to describe the characteristics of internal waves in Todos Santos Bay, Baja California (Mexico) from direct measurements made during the international experiment Fluxes Linking the Offshore with the Onshore (FLOO), which was held in August 2007. Time series of temperature and currents were obtained in the study area, placing several submerged moorings with chains of HOBO-V2 sensors and an ADCP. In addition, transects were made using a towed undulating CTD system and chains of thermographs which had a response time of 5 s. These measurements allowed the construction of the scenarios of generation, propagation and disintegration of the internal tide in the Bay. The internal tidal waves are generated by the barotropic tide at the edge of the continental shelf north of the Bay, have wavelengths ~9 km, are distributed in the form of an arc, and travel to the southeast with phase velocity ~20 cm/s . In shallow waters near the coast, tidal waves are refracted and quickly divide into groups of short nonlinear internal waves with amplitudes 15-20 m, periods 5-20 minutes, and wavelengths 50-200 m. Nonlinear internal waves play an important role in the dynamics of Todos Santos Bay, especially in the coastal zone. During partial or total destruction, vertical mixing and sudden changes of stratification take place. This affects the formation of the vertical structure of water density and ocean biological productivity.

Hepatozoon canis infecting dogs in the State of Espírito Santo, southeastern Brazil.  

PubMed

From May 2007 to March 2008, blood samples were collected from 92 healthy dogs living in 21 households (17 farms in rural area, and 4 homes in urban area) in 6 counties of the State of Espírito Santo, southeastern Brazil. In addition, ticks were collected from these dogs. A mean of 4.4+/-3.0 dogs (range: 1-12) were sampled per household; 78 and 14 dogs were from rural and urban areas, respectively. Polymerase chain reaction (PCR) designed to amplify fragments of the 18S rDNA gene of Babesia spp or Hepatozoon spp revealed amplicons of the expected size in 20 (21.7%) dogs for Babesia, and 54 (58.7%) dogs for Hepatozoon. All Babesia-positive dogs were also Hepatozoon-positive. Among the 21 households, 15 (71.4%) from 3 counties had at least one PCR-positive dog, including 13 farms (rural area) and 2 homes (urban area). A total of 40 PCR products from the Hepatozoon-PCR, and 19 products from the Babesia-PCR were submitted to DNA sequencing. All generated sequences from Hepatozoon-PCR were identical to each other, and to corresponding 18S rDNA sequences of H. canis in GenBank. Surprisingly, all generated sequences from the Babesia PCR were also identical to corresponding 18S rDNA sequences of H. canis in GenBank. Dogs from 10 rural and 2 urban households were found infested by Rhipicephalus sanguineus ticks. Immature of Amblyomma cajennense ticks were found in dogs from only 4 rural households (also infested by R. sanguineus). All but one household with R. sanguineus-infested dogs had at least one Hepatozoon-infected dog. Statistical analysis showed that the presence of ticks (i.e. R. sanguineus) infesting dogs in the households was significantly (P<0.05) associated with at least one PCR-positive dog. There was no significant association (P>0.05) between PCR-positive dogs and urban or rural households. Canine hepatozoonosis caused by H. canis is a high frequent infection in Espírito Santo, Brazil, where it is possibly vectored by R. sanguineus. Since all infected dogs were found apparently healthy, the pathogenicity of H. canis for dogs in Espírito Santo is yet to be elucidated. PMID:19482427

Stomoxys calcitrans parasitism associated with cattle diseases in Espírito Santo do Pinhal, São Paulo, Brazil.  

PubMed

The stable fly has been of great significance to livestock production in the county of Espirito Santo do Pinhal; it has a painful bite, sucks blood, and carries many diseases. The aim of this study was to establish a relationship between the parasitism of Stomoxys calcitrans, manure management, cattle diseases, and technical support. According to the farmers the stable fly reaches its highest level in the rainy season, the same period in which diseases were detected. Most of the farmers said that they did not receive technical assistance. The association of inappropriate manure management, verified in this survey, with the low frequency of technical visits, resulted in a low level of technology utilization. Better technological assistance could moderate the stable fly infestation and help manage serious cattle diseases. PMID:15604496

Paleomagnetism of the Todos Santos Formation in the Maya Block, Chiapas, Mexico: Preliminary Results  

NASA Astrophysics Data System (ADS)

Preliminary results of a paleomagnetic study on jurassic volcanic rocks (U-Pb 188.8 +/- 3.2Ma) locally interbedded with red beds assigned to the Todos Santos Formation, sampled in the Homoclinal Tectonic Province of the Neogene Fold Belt, Chiapas-Mexico, reveal multi component magnetizations acquired during pre- and post- folding of these rocks. The samples responded well to thermal demagnetization, but not so to AF demagnetization, suggesting that a high coercivity mineral phase like hematite is the main remanence carrier. The post-folding B-component direction of Dec=174.3 Inc=-30.6 (k=46; alpha95=13.6; N=4) represents a recent Tertiary? overprint; while the pre-folding C-component direction of Dec=329.9 Inc=7.8 (k=12.5; alpha95=16.3; N=8) is in agreement with a previously reported small data set for the Todos Santos Formation. When compared to the North American reference direction (Jurassic Kayenta Formation) the observed direction indicates a counterclockwise rotation of 35.9 +/- 16.6 degrees, and moderate north to south latitudinal displacement. If a reference pole from NE North America is used, the amount of counterclockwise rotation and latitudinal displacement are both slightly reduced. If the assumption that Jurassic strata in Chiapas reflect displacement of the Maya Block, then these data are consistent with reconstructions of the Maya Block in the Gulf of Mexico region. Other sites sampled in Jurassic strata suggest that in addition to the interpreted regional rotation, local (vertical-axis) rotations may have affected the region in more recent times.

Application of a geographical information system approach for risk analysis of fascioliasis in southern Espi?rito Santo state, Brazil.  

PubMed

A model based on geographical information systems for mapping the risk of fascioliasis was developed for the southern part of Espi?rito Santo state, Brazil. The determinants investigated were precipitation, temperature, elevation, slope, soil type and land use. Weightings and grades were assigned to determinants and their categories according to their relevance with respect to fascioliasis. Theme maps depicting the spatial distribution of risk areas indicate that over 50% of southern Espi?rito Santo is either at high or at very high risk for fascioliasis. These areas were found to be characterized by comparatively high temperature but relatively low slope, low precipitation and low elevation corresponding to periodically flooded grasslands or soils that promote water retention.

Authigenic chlorite as a controlling factor in the exploration of Turonian/Coniacian turbidites in the Santos Basin  

SciTech Connect

Upper Turonian/Coniacian and Campanian turbidites are major targets for petroleum exploration in the Santos Basin, southeastern Brazil. They occur between 140 and 1000 m of present water depth, are buried at about 4500 m, and reach thickness of up to 60 m. The main reservoir facies is composed of unstratified, fine to very fine grained, poorly sorted sandstones, which framework is compositionally immature, including a high proportion of feldspars and volcanic rock fragments. Early coating of grains by authigenic chlorite inhibited pressure solution and quartz cementation in the reservoir. This diagenetic characteristic allowed important preservation of primary porosity (>20%) in the reservoir; nevertheless its permeability never exceeds 30 ml. The study of sedimentary facies and related depositional processes has been conducted to predict the distribution of petroleum-bearing turbidites throughout the Santos Basin; this comprises a major challenge for the petroleum exploration in this important Brazilian exploration frontier.

Polymorphism analysis of MTHFR, factor II, and factor V genes in the Pomeranian population of Espirito Santo, Brazil.  

PubMed

Pomeranian populations worldwide immigrated originally from the north of Europe, and because of their preferential marriage, religion, and cultural habits, they show little or no reproductive mixing with local populations. Methylenetetrahydrofolate reductase gene (MTHFR) C677T, Factor V Leiden, and Factor II G20210A polymorphisms are linked to augmented clotting and their frequencies may vary according to population ethnicity. We aimed to assess the frequencies of these thrombophilic alleles in the Pomeranian population residing in Espirito Santo and compare with the general population of the Espirito Santo state, Brazil. A total of 200 individuals were analyzed. The intrapopulation fixation index of the MTHFR C677T polymorphism was 0.03736. The observed heterozygosity was 0.44 and 0.4 for the general and Pomeranian populations, respectively. According to the chi-square test, both populations are in Hardy-Weinberg equilibrium. Four polymorphic alleles were detected for Factor II (2.02%) and 8 for Factor V (4.81%). Our results show that there is gene flow between the general and the Pomeranian population of Espirito Santo, which should no longer be considered an isolated population. PMID:21919702

In vitro diagnosis of the first case of amitraz resistance in Rhipicephalus microplus in Santo Tomé (Corrientes), Argentina.  

PubMed

In Argentina, the cattle tick Rhipicephalus microplus has already developed resistance to organophosphates and synthetic pyrethroids. However, no cases of amitraz resistance have ever been recorded in this country despite its heavy use. A recent failure of amitraz to control ticks in a farm located in Santo Tomé, province of Corrientes, resulted in the collection of samples for acaricide resistance diagnosis. The modified Drummond adult immersion test (AIT) and the larval tarsal test (LTT) were performed separately in Argentina and Switzerland to evaluate efficacy of amitraz and other acaricides. The AIT showed that oviposition in the Santo Tomé field isolate was not inhibited when it was challenged to 250 and 500 ppm amitraz, and 50 ppm deltamethrin. However, oviposition was reduced by 90.6% when this field isolate was challenged to a combination of 400 ppm ethion and 100 ppm cypermethrin. To confirm the results obtained with the AIT, 2 additional tick samples were collected and shipped to Switzerland for resistance diagnosis of amitraz, cypermethrin and flumethrin, using the LTT. With this bioassay, the resistance ratios of the 2 field isolates were 32.5 and 57.0 for amitraz and between 5.9 and 27.2 for the synthetic pyrethroids. Both in vitro bioassays confirmed amitraz and synthetic pyrethroid resistance in the Santo Tomé samples. These results account for the first evidence of amitraz resistance in R. microplus in Argentina. PMID:23153823

Integrated quality assessment of sediments from harbour areas in Santos-São Vicente Estuarine System, Southern Brazil  

NASA Astrophysics Data System (ADS)

Santos-São Vicente Estuarine System is a highly populated coastal zone in Brazil and where it is located the major port of Latin America. Historically, port activities, industrial and domestic effluents discharges have constituted the main sources of contaminants to estuarine system. This study aimed to assess the recent status of sediment quality from 5 zones of Port of Santos by applying a lines-of-evidence approach through integrating results of: (1) acute toxicity of whole sediment and chronic toxicity of liquid phases; (2) grain size, organic matter, organic carbon, nitrogen, phosphorus, trace metals, polycyclic aromatic hydrocarbons, linear alkylbenzenes and butyltins; (3) benthic community descriptors. Results revealed a gradient of increasing contamination for metals and organic compounds, alongside with their geochemical carriers. Sediment liquid phases were more toxic compared to whole sediment. Low number of species and individuals indicated the impoverishment of benthic community. The use of site-specific sediment quality guidelines was more appropriate to predict sediment toxicity. The integration of results through Sediment Quality Triad approach and principal component analysis allowed observing the effects of natural stressors and dredging on sediment quality and benthic distribution. Even with recent governmental efforts to control, pollution is still relevant in Port of Santos and a threat to local ecosystems.

Automatic Estimation of the Seafloor Geomorphology of the Santos Basin, Brazil  

NASA Astrophysics Data System (ADS)

The bathymetry and acoustic backscatter of Santos Basin, Brazil were mapped using a SeaBeam 2112 (12 kHz, 151 beam) Multibeam Echosounder (MBES) aboard the R/V Falcon Explorer. This MBES data was acquired from January-November, 2000, during a high-resolution multi-channel 3D seismic survey, resulting in 380 parallel lines of 90 km length, spaced 250 m apart. The final survey mapped an area of 5,000 km{}2 in water depths of 900--2000 m. These closely spaced multibeam tracks resulted in an average overlap between swaths of 1000%, thereby ensonifying most areas of the seafloor at least ten times. Traditional (hand) processing of a dataset this dense is time-consuming and tedious, and is prone to subjective decisions and operator fatigue. However, the density of the survey makes it ideal for automatic processing methods. Recently, we have developed an algorithm called CUBE that addresses the twin concerns of robustness and reliability that are often raised about automatic processing methods. Based on a very robust multiple hypothesis Bayesian estimator, CUBE processes MBES bathymetry directly into a set of gridded products representing the best estimate of probable depth, and a measure of the uncertainty associated with this estimate. We apply CUBE to the Santos Basin data, illustrating in terms of processing time and human effort the advantages of processing such data automatically. We compare the automatically generated data with a hand-processed set, showing that the results agree to within the estimated experimental uncertainty. We next illustrate the use of CUBE as a data quality measure, indicating areas of concern in the data. Finally, we utilize the bathymetric grid resulting from CUBE to investigate the seafloor morphology, which includes a set of linear depressions parallel and perpendicular to the Shelf break. These linear depressions are the surface expression of fault planes related to subsurface salt walls. In the shallowest part, the detailed bathymetry also shows various pockmarks (350 m wide) possibly associated with fluid expulsion, while in the deeper portion we observe a small number of larger ones (2500 m wide), which are clearly inactive as they are partially filled with recent sediments. Some pockmarks are aligned with fault planes, suggesting a preferential pathway for fluid expulsion. The acquisition geometry for this survey allowed us to analyze the behavior of the backscatter response as a function of grazing angle for any given piece of seafloor, thus eliminating the need to assume a homogeneous seafloor across the swath. Although the backscatter is not calibrated, the variation in response can be used to investigate the effects of gas in shallow sediments of the survey area.

Lead poisoning among children of Santo Amaro, Bahia, Brazil in 1980, 1985, and 1992.  

PubMed

A cross-sectional epidemiologic survey conducted at the beginning of 1992 evaluated the status of lead intoxication among children from 1 to 5 years of age living within 500 meters of a primary lead smelter in the Brazilian city of Santo Amaro, Bahia. A total of 103 children in this age group were initially enrolled in the study; however, 2 were later excluded because they could not be located, and 1 was excluded from the statistical analyses for reasons noted below. The results were compared with those from similar surveys made in 1980 and 1985 in the same area with children of the same age. A blood sample was obtained from each child, the child's hematocrit and zinc protoporphyrin (ZPP) level were determined, and an interview questionnaire was used to collect information of clinical or epidemiologic interest from the child's mother or guardian. The geometric average ZPP was 65.5 micrograms/100 mL (geometric standard deviation = 1.7), a level far exceeding the upper limit of normality established by the U.S. Centers for Disease Control and Prevention of 30 micrograms/100 mL. One child was excluded from the statistical analyses because it exhibited an extremely high ZPP level (789 micrograms/100 mL). Higher average ZPP levels were found for girls, children with darker-skinned racial backgrounds, children from homes where smelter slag was commonly used around the house, children presenting pica, and children of smelter workers. Of the symptoms of lead poisoning investigated, only nervousness and easy irritability exhibited high frequencies among the children studied. However, the prevalence of above-normal ZPP levels suggestive of lead poisoning was 92.2% in 1980, 98.4% in 1985, and 97.0% in 1992. Hence, the apparent prevalence of lead poisoning continued very high in 1992, indicating that the control measures adopted were ineffective or that other unidentified and uncontrolled risk factors were playing an important role. Overall, however, the proportion of children with very high ZPP levels fell sharply, and that of children with moderately high levels also declined notably, indicating that the severity of the problem had been reduced even though new cases of intoxication continued to occur. The Santo Amaro smelter closed its doors in December 1993. PMID:8919726

Seasonal prevalence and container preferences of Aedes albopictus in Santo Domingo City, Dominican Republic.  

PubMed

The seasonal prevalence and container preferences of Aedes albopictus (Skuse) were studied in the park, Parque Mirador del Norte in Santo Domingo City, Dominican Republic, from January to December 1994. Tire ovitraps were set along a transect through the park and monitored weekly while two larval surveys were conducted in both the park and surrounding houses using standard entomological methodology. No seasonal pattern of oviposition was observed with similar numbers of positive tire traps collected in the wet and dry season. Most of the positive ovitraps were located in the middle of the park. Within ovitraps, Aedes aegypti (L.), Ae. albopictus, Culex corniger (Theobald), Ochlerotatus albonotatus (Coquillett), and Toxorhynchites sp. were collected. The larval surveys found 7 associated mosquito species, including Ae. aegypti, Ae. albopictus, Ochleotatus mediovittatus (Coquillett), Anopheles albimanus (Weidemann), Culex nigripalpus (Theobald), and Culex quinquefasciatus Say. The Ae. albopictus breeding sites were plastic buckets (4), rock holes (3), and Styrofoam lunch containers (3). We suggest that further studies should be conducted to determine its geographic distribution and vector potential in the Dominican Republic. PMID:14714670

Survey for Tick-Borne Zoonoses in the State of Espirito Santo, Southeastern Brazil  

PubMed Central

Blood samples collected from 201 humans, 92 dogs, and 27 horses in the state of Espirito Santo, Brazil, were tested by polymerase chain reaction, indirect immunofluorescence assays, and indirect enzyme-linked immunosorbent assay for tick-borne diseases (rickettsiosis, ehrlichiosis, anaplasmosis, borreliosis, babesiosis). Our results indicated that the surveyed counties are endemic for spotted fever group rickettsiosis because sera from 70 (34.8%) humans, 7 (7.6%) dogs, and 7 (25.9%) horses were reactive to at least one of the six Rickettsia species tested. Although there was evidence of ehrlichiosis (Ehrlichia canis) and babesiosis (Babesia canis vogeli, Theileria equi) in domestic animals, no human was positive for babesiosis and only four individuals were serologically positive for E. canis. Borrelia burgdorferi-serologic reactive sera were rare among humans and horses, but encompassed 51% of the canine samples, suggesting that dogs and their ticks can be part of the epidemiological cycle of the causative agent of the Brazilian zoonosis, named Baggio-Yoshinari Syndrome.

PCBs, PBDEs and organochlorine pesticides in crabs Hepatus pudibundus and Callinectes danae from Santos Bay, State of São Paulo, Brazil.  

PubMed

The occurrence of persistent organic pollutants (POPs) as polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDE) in crabs Hepatus pudibundus and Callinectesdanae was assessed from two different places inside of the Santos Bay and Moela Island near one of the most economically important metropolitan areas in Southern Brazil. Among POPs analyzed, ?PCBs (222-923 ng g(-1)lipid weight) and ?DDTs (154-410 ng g(-1)lw) exhibited the highest concentrations in the crabs. ?HCHs ranged from 10.3 to 30.9 ng g(-1)lw and were found in all individuals. Other OCPs found in lower concentration was Mirex (7.6-41.6 ng g(-1)lw) and HCB (5.83-16.9 ng g(-1)lw). ?PBDEs (24.1 ng g(-1)lw) were only found in one male individual from the species C. danae collected near to the submarine sewage of Santos. Male crabs showed higher POP concentrations than female crabs for those two species. PMID:22245435

Effects of ayahuasca on psychometric measures of anxiety, panic-like and hopelessness in Santo Daime members.  

PubMed

The use of the hallucinogenic brew ayahuasca, obtained from infusing the shredded stalk of the malpighiaceous plant Banisteriopsis caapi with the leaves of other plants such as Psychotria viridis, is growing in urban centers of Europe, South and North America in the last several decades. Despite this diffusion, little is known about its effects on emotional states. The present study investigated the effects of ayahuasca on psychometric measures of anxiety, panic-like and hopelessness in members of the Santo Daime, an ayahuasca-using religion. Standard questionnaires were used to evaluate state-anxiety (STAI-state), trait-anxiety (STAI-trait), panic-like (ASI-R) and hopelessness (BHS) in participants that ingested ayahuasca for at least 10 consecutive years. The study was done in the Santo Daime church, where the questionnaires were administered 1h after the ingestion of the brew, in a double-blind, placebo-controlled procedure. While under the acute effects of ayahuasca, participants scored lower on the scales for panic and hopelessness related states. Ayahuasca ingestion did not modify state- or trait-anxiety. The results are discussed in terms of the possible use of ayahuasca in alleviating signs of hopelessness and panic-like related symptoms. PMID:17532158

A study of multidrug-resistant tuberculosis in risk groups in the city of Santos, S?o Paulo, Brazil  

PubMed Central

Monitoring the extent of and trends in multidrug-resistant tuberculosis (MDR-TB) is a priority of the Brazilian National Tuberculosis Control Programme. The current study aimed to estimate the incidence of MDR-TB, describe the profile of TB drug resistance in risk groups and examine whether screening for MDR-TB adhered to the recommended guidelines. A descriptive study that examined diagnosed cases of pulmonary TB was conducted in the city of Santos, Brazil, between 2000–2004. Of the 2,176 pulmonary TB cases studied, 671 (30.8%) met the criteria for drug sensitivity testing and, of these cases, 31.7% (213/671) were tested. Among the tested cases, 9.4% were resistant to one anti-TB drug and 15% were MDR. MDR was observed in 11.6% of 86 new TB cases and 17.3% of 127 previously treated cases. The average annual incidence of MDR-TB was 1.9 per 100,000 inhabitants-years. The extent of known MDR-TB in the city of Santos is high, though likely to be underestimated. Our study therefore indicates an inadequate adherence to the guidelines for MDR-TB screening and suggests the necessity of alternative strategies of MDR-TB surveillance.

Characterization of the lead smelter slag in Santo Amaro, Bahia, Brazil.  

PubMed

For 33 years, a primary lead smelter operated in Santo Amaro (Brazil). Since the 1970s, large amounts of Pb and Cd have been widely documented in the blood and hair of people living near the smelter. The plant closed down in 1993, and several years later, the Pb levels in the blood of children under 4 years of age living near the smelter were high, where the disposed lead slag was suspected to be the main source of this contamination. The objective of this study is to elucidate the source of the Pb contamination and any other potentially toxic contamination, focusing on the characterization of the slag. The samples used for this characterization study were taken from the slag heaps. The results of the chemical analysis showed that the major constituents of the slag, in decreasing order of wt%, were the following: Fe(2)O(3) (28.10), CaO (23.11), SiO(2) (21.39), ZnO (9.47), MgO (5.44), PbO (4.06), Al(2)O(3) (3.56), C (2.26), MnO (1.44), Na(2)O (0.27), S (0.37), K(2)O (0.26), and TiO(2) (0.25). The Cd content of the slag was 57.3mg/kg, which is relatively low. The X-ray diffraction and the electron probe microanalyzer X-ray mapping indicated that the major phases in the slag were wüstite, olivine, kirschsteinite, and franklinite. Only spheroidal metallic Pb was found in the slag. The leaching study showed that the slag was stable at a pH greater than 2.8, and only in an extremely acidic environment was the solubilization of the Pb enhanced significantly. The solubilization of Zn was very limited in the acidic and alkaline environments. These results can be explained by the limited leachability of the metallic Pb and Zn-bearing compounds. The leaching study used TCLP, SPLP, and SWEP and indicated that the lead slag was stable in weak acidic environments for short contact times. PMID:21440365

2D/3D Electromagnetic sounding and well log integration on Santos Basin, Brazil  

NASA Astrophysics Data System (ADS)

Magnetotellurics (MT) is a naturally induced electromagnetic technique used to map resistivity contrasts in the subsurface of the earth. The method uses the time-varying natural electric and magnetic fields incident on the earth's surface as signal source. The method has been successfully used to achieve marine exploration objectives such as imaging sub-basalts, carbonates and subsalts in situations where seismic imaging is poor. A marine magnetotelluric survey on Santos basin in the southeast of Brazil has generated high quality data in 96 sites split in three parallel profiles in NW-SE direction along a 160 km central line and two other lines, east and west, with approximately 54 km long each one. All sites were submitted to some stages of processing to avoid noise amount and reach quality improvement. Firstly, we start applying 2D inversion to MT data and we obtained two-dimensional models with very good resolution for the three profiles and they are consistent each other. We have used well log data to provide priori resistivity information for magnetotelluric models and make correlation from different data sets. The study points out that the profiles can be imaged by two-dimensional except by small parts in the models with low misfits. These parts are associated with some interesting geological structures of highlighted importance as salt domes and diapirs. The halokinetic structures have special geometries hence they are better explained by three-dimensional approach. However, it is more appropriate utilize a 3D imaging in order to reach the best model with minor uncertainties. Recently, the number of publications regarding 3D magnetotelluric inversion has increased and it is due to the fact of the effort in performing a better characterization of the research area. It is because the magnetotelluric method has been increasingly accepted as powerful technique capable to predict valuable information. Currently we are performing a 3D inversion using all profiles with a grid of approximately 160 x 6 km2 and the first results will be shown at the meeting.

Style and pattern of salt diapirs due to thin-skinned gravitational gliding, Campos and Santos basins, offshore Brazil  

NASA Astrophysics Data System (ADS)

Portions of seismic lines and a structure-contour map illustrate the patterns and shapes of salt diapirs and related structures in the Campos and Santos areas, off the Atlantic coast of Brazil. We interpret the structures both kinematically and mechanically, drawing on our experience with similar salt structures worldwide, with the results of recent physical modelling and with geometric restorations in section and in plan. Salt diapirs and related structures have a variety of structural styles, distributed in domains and provinces. Near the coast, there is an upper domain, 100 200 km wide, with a suite of structures that we attribute to horizontal downdip extension: these are salt rollers, in the footwalls of listric normal growth faults; salt walls of triangular cross section, beneath intersecting conjugate normal faults; turtle anticlines; and salt welds. Downslope extension started in the Albian and has continued to the present day. In the Campos area, from simple line balancing, the accumulated downslope displacement is about 100 km. Seawards of this, there is a lower domain, 100 400 km wide, with a different suite of structures, that we attribute to downdip contraction: these are growth folds of various wavelengths, in sedimentary sequences of various thicknesses; asymmetric salt walls, emplaced above reverse faults; deep basins, wedged down between conjugate reverse faults; and salt tongues above thrusts. For Campos, we estimate the total downslope contraction, accumulated since the Albian, to be about 100 km. From the balance between extension and contraction, we infer that the thin-skinned salt tectonics are gravitationally driven and independent of any basement tectonics. The structure-contour map on the top of the salt shows that structural style is variable also along strike. Seismic sections along regional contours indicate differing amounts of strain. On this basis, we distinguish five provinces, separated by NW-SE-trending lines. For the Northern Campos province, we infer radially convergent gliding; for the Campos or Cabo Frio provinces, radially divergent gliding; and for Northern Santos, divergent gliding at a large scale. The pattern in Southern Santos is complicated by right-lateral wrenching against the southern edge of the salt.

Shelf-edge sedimentary systems off Rio de Janeiro State, northern Santos basin-Brazil  

NASA Astrophysics Data System (ADS)

The sedimentary record of the continental shelf off Rio de Janeiro State is related to the opening and evolution of Atlantic Ocean. The combined analysis of high resolution seismic acquired in the early 80's (Geomar cruises) and 2D seismic lines of petroleum industry, coupled with chronostratigraphic data from oil industry's exploratory wells, allowed us to observe two different orders of sequences: of 3-4th order, that represents sedimentary units related of the Milankovitch cycles (100/40/20ky), and of 2nd order (10-100my). High resolution seismic allowed us to outline a first architectural framework for the actual shelf that is composed of stacked seismic units making up the major seismic sequences bounded by angular unconformities. According to the intern and extern configuration of their clinoforms, the seismic sequences were grouped into two distinctive stratigraphic sets, identified as Set I (Pliocene) and Set II (Upper Quaternary). Some architectural components of note include: (1) the characteristic upbuilt-outbuilt geometry of sequences that compose Set I (SqA, SqB and SqC), indicating that deposition has probably been favoured by a combination of prevailing subsidence regime (upbuilt pattern) accompanied by forced regressive deposits (outbuilt pattern); (2) the majority of sequences that make up Set II outbuilts as a composite seaward-thickening progradational wedge formed under dominant forced regression conditions, implying that the generation of accommodation space was less important than during the build-up of Set I. However, these sequences consistently pinch out in a progressively landward direction, suggesting a prevailing and increasing subsidence regime able to induce the progressive seaward tilting of the margin during the middle-late Pleistocene, and the subsequent partial preservation of regressive sequences of about 100-200 m thick at the level of the present-day mid-shelf, that prograded seaward for circa 15-25 km. These architectural elements provide a hint at a prevailing subsidence regime and effective sediment supply into the basin that clearly contrast with the conveyed idea of a sediment-starved and tectonic stable shelf. They naturally raise questions about the nature and origin of sediment supply, since no significant point siliciclastic fluvial source flows directly into the shelf. Stemming from that, we are forced to speculate about: (A) the role of neotectonic movements involving the Serra do Mar coastal mountain ranges to potentially source clastic influx into the basin during the Quaternary, or about the real importance of secondary drainage basins debouching today; and (B) the mechanical nature of a supposed subsidence during the Pliocene and the Quaternary time span (overloading ? sediment compaction ? thermal cooling ?). The interpretation of industrial seismic lines can provide the answers of many of these questions. The next step of this work is to make a stratigraphy model of the sedimentary systems of Santos basin to understand how the ancient creation of accommodation space can influence the recent sedimentary architecture and how is the change in sedimentary influx and the sedimentary records of different orders of cyclicity.

Hydrography of Bahia Todos Santos, Baja California: Results of more than twenty five years of investigations.  

NASA Astrophysics Data System (ADS)

The first study of Bahia Todos Santos (BTS) was reported by Walton in 1955. We conducted oceanographic studies in BTS since 1979. The BTS has a connection with a coastal lagoon named Estero de Punta Banda (EPB), two islands at the western portion and the Port of Ensenada. The general hydrographic characteristics are: In winter the water became homogeneous, less saline (<33.4) and with low stability. During spring and summer a hydrographic structure of three layers is noticed. The deepest layer is composed of the southern California water mass with a relatively high salinity (>33.6) low temperature (13°C), low oxygen (~3mL L-1) and rich in nutrient concentration. The isothermal top layer has relatively high temperature (>17°C) and oxygen concentration (>6mL L-1). The intermediate transition layer (seasonal thermocline) has minimum salinity, maximum oxygen and high stability. During fall there is distribution of heat from the surface layer to the entire water column. The thermic waves propagate with decrease amplitude in ~3 months, from surface to bottom water. The California Current flow generally southward off the western United States and northern Mexico and is one of the major coastal upwelling of the word oceans. The upwelling events in BTS appear regularly at the SW portion and were typically characterized by an increase in pCO2, decrease of O2, increase of nutrients and a lower temperature. Upwelling activity increases surface nutrient availability causing rise in the primary productivity and hence increased zooplankton biomass. The annual upwelling event which had a maximum strength on May, the seasonal warming and cooling, and the water advection were the dominant modifying processes for the variability of seawater characteristics. Higher salinities are located close to the coastline and lower off the bay. The levels of oxygen, alkalinity, pH and chlorophyll indicate that the maximum concentration of phytoplankton is located at the center of the bay. The nitrification support the primary productivity and the NO3 levels were below detection limits; the N/P ratio in 2005 was from 10 to 25; and for 2006 was below 5. There is a net enrichment of anthropogenic nutrients at BTS. The heavy metals and pesticides studies started since the early 80's with problems still to solve for Tl, Cd. There is a net Pb enrichment and higher Cr concentrations at the NE of the bay. The EPB is a wetland ~7 Km. long located at the SE part of the BTS. The EPB is a net source of DIP (deltaDIP = +0.13 mmol m-2 day-1), that brings agricultural runoff to the BTS. It is typically a hypersaline system during summer and a net heterotrophic (p-r = -14 mmol m-2 day-1), and a net denitrifying (nfix-denit = -2.1 mmol m-2 day-1) system. Some anomalies were in 2005 the presence of a huge red tide observed inside BTS (about 50% of the bay) that last for more than six months, this HAB's has killed many fishes (anoxia) and marine mammals. The hydrographic conditions during the red tide were, temperature anomalies higher than 2°C above normal; high nutrient concentration above the normal. In 2006 the values were normal again. The Port of Ensenada, increased in size and activities (tourism, transportation, coastguards for national security, cement industry, research) these developments generate some management problems, like the beach and coastline modification. The aground of the APL Panama, activates the management agencies to prevent and control pollution.

Assessment of metal concentrations in muscles of the blue crab, Callinectes danae S., from the Santos Estuarine System.  

PubMed

This study determined the concentrations of eleven metals in the blue crab, Callinectes danae, from nine sites in the Santos Estuarine System of Sao Paulo State, Brazil. The results were compared to guidelines established in the United States, Europe and Brazil for the safety of human consumers. Muscles of blue crabs were removed by dissection and concentrations of Al, Cd, Co, Cr, Cu, Fe, Hg, Mn Ni, Pb and Zn were determined. In general, the concentrations of metals were low, and the crabs were regarded as safe for human consumption. Crabs from a single site (site 4) exceeded the guidelines established by the United States and Europe, but not Brazil, for Pb, with a mean tissue concentration of 1.725 ?g g(-1). With the exception of Al, Fe and Ni, significant differences were noted between sites in the concentrations of each metal in crab tissue. PMID:22782356

Low Sensitivity of NS1 Protein Tests Evidenced during a Dengue Type 2 Virus Outbreak in Santos, Brazil, in 2010  

PubMed Central

In 2010, a large outbreak of dengue occurred in Santos, Brazil. The detection of the NS1 antigen was used for diagnosis in addition to the detection of IgG, IgM, and RNA. A large number of NS1 false-negative results were obtained. A total of 379 RNA-positive samples were selected for thorough evaluation. NS1 was reactive in 37.7% of cases. Most of the cases were characterized as a secondary infection by dengue 2 virus. Sequencing of NS1 positive and negative isolates did not reveal any mutation that could justify the diagnostic failure. Use of existing NS1 tests in the Brazilian population may present a low negative predictive value, and they should be used with caution, preferentially after performing a validation with samples freshly obtained during the ongoing epidemic.

The Cerrillos Uplift, the La Bajada Constriction, and Hydrogeologic Framework of the Santo Domingo Basin, Rio Grande Rift, New Mexico  

USGS Publications Warehouse

The geologic, geophysical, and hydrogeologic properties of the La Bajada constriction and Santo Domingo Basin, northern New Mexico, result from tectonic and volcanic processes of the late Tertiary and Quaternary Rio Grande rift. An integrated geologic and geophysical assessment in the La Bajada constriction allows development of a geologic framework that can provide input for regional ground-water flow models. These models then can provide better estimates of future water supplies in a region that largely subsists on aquifers in Rio Grande rift basins. The combination of surface geologic investigations (stratigraphic and structural studies; chapters A, B, C, and E), airborne geophysics (aeromagnetic and time-domain electromagnetic surveys; chapters D and F), ground geophysical measurements (gravity and magnetotelluric surveys; chapters D and F), and data from the few wells in the area (chapter G) provides new constraints on the hydrogeologic framework of this area. Summary results of our investigations are synthesized in chapter G. Through-going aquifers consisting of ancestral Rio Grande axial-river sand and gravel and of coarse western-piedmont gravel form the predominant ground-water pathways through the partly buried structural trough defining the La Bajada constriction between Espa?ola and Santo Domingo Basins. Thick, clay-rich Cretaceous marine shales of low hydraulic conductivity form a pervasive regional confining unit within the Cerrillos uplift on the southeast flank of the constriction. Numerous, dominantly north-northwest-striking, intrabasin faults that project part way across the La Bajada constriction create a matrix of laterally and vertically variable hydrogeologic compartments that locally partition and deflect ground-water flow parallel to faults.

Genetic analysis of 15 autosomal and 12 Y-STR loci in the Espirito Santo State population, Brazil.  

PubMed

This study provides population genetic data for individuals of Vitoria, Espirito Santo, Brazil, a location not yet characterized for STR frequencies used for genetic identification studies. Allelic frequencies and other population data analysis are reported for the 15 autosomal-STR loci included in the PowerPlex(®)16 kit (CSF1PO, D13S317, D16S539, D18S51, D21S11, D3S1358, D5S818, D7S820, D8S1179, FGA, Penta D, Penta E, TPOX, TH01 and vWA). Allele and haplotype frequencies, gene diversity and discrimination capacity were also estimated for the PowerPlex(®) Y System (DYS19, DYS385, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439). Blood samples were obtained from 226 unrelated volunteers (135 males and 91 females) residents in the city of Vitoria, representing a typical sample of the mixed ethnicity present in the Espirito Santo State, Brazil. Within the tested population, the total number of individuals typed for specific markers is: 226 for D13S317, D21S11, D3S1358, D7S820, D8S1179 and FGA; 225 for D16S539 and D5S818; 224 for D18S51; 223 for CSF1PO; 222 for Penta D and vWA; 220 for Penta E; 207 for TPOX and 142 for TH01. Y-STR haplotypes were analyzed for 102 unrelated males, being 71 of them present in the 135 autosomal-STR sample, and 31 new males tested only for Y-STR markers. All autosomal markers were in Hardy-Weinberg Equilibrium. Y-STR analysis identified 101 haplotypes, being 100 of them unique. PMID:20965142

Relationship between metal enrichments and a biological adverse effects index in sediments from Todos Santos Bay, northwest coast of Baja California, México.  

PubMed

In 1992 and 2004, heavy metals concentrations were measured in surficial sediments from Todos Santos Bay, located in Ensenada, Baja California, Mexico. The aim was to search for relationships between metal enrichment factors and a biological adverse effects index. Unlike Ni, the elements Cd, Cu and Zn showed significant correlations (p<0.05) between enrichment factors and the biological adverse effects index. Cu showed a 0.74:1 relationship, which means that any enrichment above 0.74 could represent biological adverse effects. On the other hand, Cd and Zn enrichments must be >5.5 and >1.5, respectively, in order for the sediments to be considered toxic. In general, data showed that most of the metal concentrations in Todos Santos Bay sediments could not cause adverse effects to biota. Only Ensenada's harbor and the zone next to a dredging dumping site showed metal enrichments that could be toxic. PMID:22196693

Individual determinants of fish choosing in open-air street markets from Santo André, SP/Brazil.  

PubMed

The objective of this study was to identify the determinants of fish consumption in the population that attends open-air street markets in the city of Santo André, SP, Brazil.We performed a survey, covering approximately 482 people in 49 street markets.It consisted of free-answer questions, half open choice and half multiple-choice options, for the identification and evaluation of socioeconomic factors that facilitate and hinder fish consumption.A descriptive analysis of the data and further tests were used to determine the association between variables and linearity with consumption, with a significance level of 5%. The most commonly cited types of fish consumed were hake, sardine and dogfish. The factors that facilitate the purchase and consumption of fish are listed as follows: a preference for purchasing fish at street markets, appearance, firmness, fresh presentation, frozen presentation, as well as the respondent's education and individual monthly income. Limiting factors were identified as the price and the presence of spines. Perishability, odour, ethnicity, proximity to points of sale of residence and work, gender, age, number of people in the household, presence of children and acquisition supermarket were not characteristics that influenced decisions about fish consumption.

Environmental analyses of the parasitic profile found in the sandy soil from the Santos municipality beaches, SP, Brazil.  

PubMed

The environmental contamination by geohelminths represents a world public health problem and has been well documented by several authors. However, few papers describe the presence of such contamination in saline soils of coastal beaches. A study was performed on the beaches of the municipality of Santos in the period between May 2004 to April 2005 with the aim of determining the degree of contamination, and the correlation between contamination level and seasonal conditions and characteristics of the environment. Of the 2,520 samples analyzed, 18.2% (458) were contaminated, 32.3% (148) of which were localized in children's recreational areas (playgrounds). The parasite profile found in the analyzed samples indicated the presence of several zoonotic parasites: Ancylostoma larvae (82.5%), Toxocara sp. eggs (59.4%), Ancylostomidae-like eggs (37.1%), coccid oocysts (13.5%), Trichostrongylus sp. eggs and larvae, Ascaris lumbricoides eggs, (11.6%), Entamoeba sp. cysts (10.0%), Strongyloides sp. (4.8%), several free nematoids and some non-identified parasitic structures (3.3%). It was established that the highest frequency of parasitic structures occurred in the months between May and October 2004, and from February to March 2005. An increase in the diversity of parasitic forms was documented in the months between February to December 2004 and from January to April 2005, these periods having the highest rainfall.

[The genera of Bethylidae (Hymenoptera: Chrysidoidea) in four areas of Atlantic Rain Forest from Espírito Santo, Brazil].  

PubMed

The generic richness and abundance of Bethylidae collected in four different hillside areas of Atlantic rain forest from Espírito Santo, Brazil were studied. The sites are Santa Maria de Jetibá (SMJ), Domingos Martins (DM), Pancas (P) and Atílio Vivacqua (AV). A total of 2,840 specimens of 12 genera were collected. Lepidosternopsis Ogloblin and Bakeriella Kieffer are first recorded from the State. Richness of taxa was calculated using first-order Jackknife richness with EstimateS program. Genera accumulation curves were ran to evaluate the samples. Abundance data were adjusted to the geometric distribution. Parameter k was used to compare areas. The generic profile was not equal for the sites we studied. The areas were considered disturbed. SMJ and DM presented genera richness bigger than in P and AV. The differences in the sites reflect the different preservation of each environment. Pseudisobrachium Kieffer and Dissomphalus Ashmead are most dominant genera in SMJ, DM and P, and Anisepyris Kieffer in AV. This study emphasizes the fact of Dissomphalus as the most abundant genus in rain forests. The generic profile found in AV is similar to that of some areas of Brazilian savannah. PMID:18506293

Geochemical and biostratigraphic characterization of an upper Cretaceous organic-rich condensed section in the Santos Basin, Brazil  

SciTech Connect

The Cenomanian-Turonian section is worldwide recognized as an organic- rich interval associated with a widespread anoxic event. Samples from this interval, representing proximal sedimentary conditions have been well characterized in the Santos Basin, Brazil, where it reaches 300m thickness. The main objective of this study is to characterize the geochemical and paleoecological attributes as well as to ascertain the biostratigraphic position of this organic-rich section in a more distal location, at ODP Site 356. Biostratigraphic analyses identify die interval at ODP Site 356 as a condensed section ranging in age from Cenomanian to Coniacian (11 m), deposited under anoxic conditions associated with a warm, and climate in the adjacent continental areas. Geochemical analyses indicate high total organic carbon contents (up tp 6.7%), dominance of algal derived material, high relative abundances of homohopanes and methylsteranes, [delta][sup 13]C around -27[per thousand], indicating a typical marine anoxic section. Despite the high content of oil-prone organic matter, this section has not attained thermal evolution appropriated for hydrocarbon generation due to its shallow burial. In proximal areas of the basin, this section is interpreted as a transgressive system tract which is composed by a series of sequences, that are enriched in organic material at their bases. Basinward the interval is thinner, but presents higher organic carbon contents according to geochemical data of ODP Site 356, typical of a condensed section.

Evaluation of the water genotoxicity from Santos Estuary (Brazil) in relation to the sediment contamination and effluent discharges.  

PubMed

The genotoxic activity of water samples collected in 9 different sites within the area of the Santos estuary was preliminary evaluated, and related to previous data on the genotoxicity of sediments and the contents of PAHs in both water and sediment samples. The liquid discharge of a steel mill (coke plant), known to be mutagenic, was chemically analyzed to determine its PAH content. For the water evaluation we employed the Salmonella/microsome assay with the strains TA98 and TA100 with and without S9 mix in the plate incorporation method. The water was filtered with an AP20 membrane before being extracted with XAD4 at natural and acidic pH. The industrial effluent was filtered in 0.45 microm membranes before being extracted with the liquid/liquid method. Both membranes containing the particulate material were extracted using ultrasonication. PAHs were found associated with the suspended particles present in the industrial effluent in accordance with mutagenicity data previously reported. In relation to the estuarine waters, sites 1 and 5 presented low levels of mutagenic activity only in the filtered water (liquid fraction) extracts. At site 3, both the filtered water and particulate solids presented also low mutagenicity. Results show that the mutagenic activity observed in water could not be directly related to the genotoxic activity and PAHs contents of the bottom sediments. PMID:16216325

Overview of the 20th century impact of trace metal contamination in the estuaries of Todos os Santos Bay: past, present and future scenarios.  

PubMed

This paper discusses the distribution patterns of trace metals in sediments and suspended particulate matter (SPM) in the three main estuaries of the Todos os Santos Bay (BTS), Brazil, during dry and rainy seasons. Data available up to 2012 was also reviewed to assess the status of contamination. For most elements, metal concentrations in sediments decreased from the tidal limits to the lower estuary. Metals in SPM presented more complex distributions along the salinity gradient. Metal variability between rainy and dry conditions was only significant for SPM data. Of the BTS estuaries, the levels of Cd, Zn, Pb and Cu are highest in the Subaé estuary, and they seem to be promoting harmful biological effects in macrofauna, and also may pose potential human health risks. Despite the evidence of important localized contamination, much of the data compiled indicates that the bay and its estuaries are still relatively preserved. PMID:22841387

Seismic and experimental evidence for thin-skinned horizontal shortening by convergent radial gliding on evaporites, deep-water Santos Basin, Brazil  

SciTech Connect

Thin-skinned gravitational gliding of sediments above a detachment layer of salt or shale is common on passive margins. Changes in surface slope result in a domain of extension upslope and a domain of contraction downslope. Contractional domains tend to occur under present-day deep water and are thus now well understood. In the deep-water Santos Basin, Brazil, a contractional domain contains a suite of salt-cored structures. Angular folds (chevron and box folds), as well as concentric folds, are common in the upper part of the Aptian evaporite sequence, which appears to comprise alternating layers. In general, angular and concentric folds form by flexural slip during shortening of mechanically layered sequences. Their occurrence in the Santos Basin is evidence in favor of horizontal contraction. The lower part of the Aptian evaporite sequence appears to be mostly rock salt. It has been squeezed has been thickened or even repeated across thrust faults and ramp anticlines. An overlying sequence of open-marine sediments has been condensed or eroded over anticlines but forms local depocenters. These depocenters are asymmetric (of foreland style) next to isolated thrusts but symmetric in synclines or between thrusts of opposite vergence. The structural styles have been reproduced in physical models, properly scaled for gravitational forces, in which salt is represented by silicone putty and sediments are represented by sand. The models were shortened horizontally by a screw jack. The experiments illustrate the importance of horizontal contraction and syntectonic sedimentation in shaping salt-cored structures. They have been used to establish criteria that may diagnostic of contraction.

Etiology of liver cirrhosis in Brazil: chronic alcoholism and hepatitis viruses in liver cirrhosis diagnosed in the state of Esp?rito Santo  

PubMed Central

OBJECTIVES: To report the etiology of liver cirrhosis cases diagnosed at the University Hospital in Vitoria, Espirito Santo, Brazil. METHODS: The medical charts of patients with liver cirrhosis who presented to the University Hospital in Vitoria were reviewed. Chronic alcoholism and the presence of hepatitis B or C infections (HBV and HCV, respectively) were pursued in all cases. RESULTS: The sample consisted of 1,516 cases (male:female ratio 3.5:1, aged 53.2±12.6 years). The following main etiological factors were observed: chronic alcoholism alone (39.7%), chronic alcoholism in association with HBV or HCV (16.1%), HCV alone (14.5%) and in association with alcoholism (8.6%) (total, 23.1%), and HBV alone (13.1%) and in association with alcoholism (7.5%, total 20.6%). The remaining etiologies included cryptogenic cases (9.8%) and other causes (6.0%). The mean patient age was lower and the male-to-female ratio was higher in the cirrhosis cases that were associated with alcoholism or HBV compared with other causes. Intravenous drug abuse and a history of surgery or blood transfusion were significantly associated with HCV infection. Hepatocellular carcinoma was present at the time of diagnosis in 15.4% of cases. Chronic alcoholism associated with HCV infection was significantly associated (p<0.001) with reduced age (at the time of cirrhosis diagnosis) and increased prevalence of hepatocellular carcinoma (p?=?0.052). CONCLUSION: Alcoholism, HCV and HBV are the main factors associated with liver cirrhosis in the state of Espirito Santo. Chronic alcoholism associated with HCV infection reduced the age of patients at the time of liver cirrhosis diagnosis.

Migratory flows and foraging habitat selection by shorebirds along the northeastern coast of Brazil: The case of Baía de Todos os Santos  

NASA Astrophysics Data System (ADS)

Large numbers of Nearctic shorebirds migrate and winter along the coast of northeastern Brazil, but there is little information on their migratory flows, foraging ecology, and on the structure of the species assemblages that they form with resident shorebirds. We studied these issues on intertidal flats of Baía de Todos os Santos (Bahia), the second largest bay in Brazil. During a full year cycle we carried out weekly bird counts in an intertidal area of 280 ha divided in sectors, where we also measured environmental parameters. The analyses of weekly counts resulted in a detailed phenology of use of the area by shorebirds. Five species were resident and ten were Nearctic migrants. Several of the latter had clear peaks in numbers in March and October, revealing the use of the bay as a stopover during both the north-bound and south-bound migration flows. A canonical correspondence analysis of the relationship between environmental parameters and bird numbers indicated that the foraging bird assemblage could be divided into five main groups, occupying distinct ecological gradients in the study area. The most important factors driving this structure were invertebrate prey abundance, percentage of fine sediments, area of mangrove cover and distance to channels. Our findings imply that maintenance of the diversity of intertidal habitats in this bay is crucial to satisfy the particular habitat requirements of resident and migrant shorebirds using the northeastern coastal regions of Brazil.

Uranium content and dose assessment for sediment and soil samples from the estuarine system of Santos and Sao Vicente, SP, Brazil.  

PubMed

In this work, the uranium (U) content in sediment and soil samples collected near the Santos and São Vicente estuaries was determined using the fission track registration technique (SSNTD). The sediment and soil samples after oven-dried and pulverised were prepared in the solution form. About 10 microl of this solution was deposited on a plastic detector and irradiated at the IPEN-IEA-R1 (3.5 MW) nuclear reactor. After the irradiation and chemical etching of the plastic foils, the fission tracks were counted with a system consisting of an optical microscope together with a video camera and a PC. The U content in the analysed samples ranged from 3.12 +/- 0.55 to 18.3 +/- 1.2 ppm for sediments and from 3.21 +/- 0.63 to 11.5 +/- 1.1 ppm for soils or in terms of (238)U equivalent activity from 38.5 +/- 6.8 to 226 +/- 15 and 39.6 +/- 7.8 to 142 +/- 14 Bq kg(-1) for sediments and soils, respectively. These results were compared with other values reported in the literature for sediments and soils collected in environments similar to the ones studied in this work. Most of the values obtained in this work are higher than the world mean and are in reasonable agreement with results found by other authors for sediments and soils from regions considered as polluted or with a high level of radioactivity.

Entomological characterization and natural infection of anophelines in an area of the Atlantic Forest with autochthonous malaria cases in mountainous region of Espírito Santo State, Brazil.  

PubMed

Autochthonous malaria cases in the state of Espírito Santo, Brazil, are distributed in mountainous regions surrounded by the Atlantic Forest. While some aspects of this disease are unclear, detection of possible vector species can help to elucidate epidemiological uncertainties. Entomological and natural infection studies were carried out using anophelines (Diptera: Culicidae) captured in the municipality of Santa Tereza, ES. Monthly captures were made from March 2004 to February 2006. CDC-CO2 traps were used from dusk (6:00 P.M.) to dawn (6:00 A.M.) to capture anophelines in the following habitats: near the houses, in open areas (at ground level) and inside, and at the margins of the forest (canopy and ground level). Shannon light traps were also used at the same locations of the CDC-CO2 traps. A total of 2,290 anophelines within 10 species were captured. The relative frequency of Anopheles (Kerteszia) cruzii Dyar & Knab / A.(K.) homunculus Komp was the highest, with the majority captured in CDC-CO2 traps installed in the forest canopy. The main species captured in Shannon traps was A.(Nyssorhynchus) strodei Root. The largest number of anophelines was captured from July to September and from 6:00 P.M. to 10:00 P.M. Anopheles (K.) cruzii is the probable vector for malaria transmission inside or near the Atlantic Forest fragments, but the role of other species cannot be ignored, as 53% of the sampled anophelines belonged to the subgenus Nyssorhynchus. The natural infection of A. cruzii, A. parvus (Chagas) and A. galvaoi Causey, Deane & Deane by Plasmodium vivax detected by PCR from DNA extracted from their thoraxes supports this view.

Transmitted Drug Resistance Among Antiretroviral-Naive Patients with Established HIV Type 1 Infection in Santo Domingo, Dominican Republic and Review of the Latin American and Caribbean Literature  

PubMed Central

Abstract Emergence of HIV resistance is a concerning consequence of global scale-up of antiretroviral therapy (ART). To date, there is no published information about HIV resistance from the Dominican Republic. The study's aim was to determine the prevalence of transmitted drug resistance (TDR) to reverse transcriptase and protease inhibitors in a sample of chronically HIV-1-infected patients in one clinic in Santo Domingo. The data are presented in the context of a review of the TDR literature from Latin America and the Caribbean. Genotype testing was successfully performed on 103 treatment-naive adults planning to initiate antiretroviral therapy; the World Health Organization (WHO) list of surveillance drug resistance mutations (SDRM) was used to determine the presence of TDR mutations. WHO SDRM were identified in eight patients (7.8%); none had received sdNVP. There were no significant differences in epidemiologic or clinical variables between those with or without WHO SDRM. The prevalence of WHO SDRM was 1.0% and 6.8% for nucleoside reverse transcriptase inhibitors and nonnucleoside reverse transcriptase inhibitors, respectively. No WHO SDRMs for protease inhibitors were identified. Among 12 studies of TDR in the region with a sample size of at least 100 subjects, the reported prevalence of SDRM ranged from 2.8% to 8.1%. The most commonly identified SDRM was K103N. This information adds to our understanding of the epidemiology of TDR in the region and the possible role such mutations could play in undermining first-line treatment. Ongoing surveillance is clearly needed to better understand the TDR phenomenon in the Caribbean.

Epidemiological profile of adult patients with tuberculosis and AIDS in the state of Esp?rito Santo, Brazil: Cross-referencing tuberculosis and AIDS databases*  

PubMed Central

Objective To evaluate the epidemiological profile of patients with tuberculosis (TB) only and that of patients with TB/AIDS in the state of Espírito Santo, Brazil, between 2000 and 2006. Methods For the patients of interest, we collected demographic and clinical data from the Epidemiological Surveillance Center (TB database), Brazilian Case Registry Database, and Brazilian National Mortality Database, as well as the Brazilian National CD4+/CD8+ T Lymphocyte Count and Viral Load Network Laboratory Test Control System and the Logistic Medication Monitoring System (HIV/AIDS databases). All of the compiled data were cross-referenced. Results During the study period, we identified 9,543 TB patients > 15 years of age, 437 of whom (4.6%) had AIDS. The median age did not differ between TB/AIDS and TB-only patients (35 years vs. 38 years). Of the 437 TB/AIDS patients, 298 (68.2%) were male, and 156 (35.8%) were in the 30–39 age bracket. In terms of TB treatment outcome, 79.0% were cured, 9.7% were referred to other facilities, 6.0% died, 5.2% abandoned treatment, and 0.2% developed multidrug-resistant TB. Death was 4.75 times more common in patients with TB/AIDS than in those with TB only. Pulmonary TB accounted for 82.4% of the cases. The combination of pulmonary and extrapulmonary TB was 8.2 times more common in the TB/AIDS patients than in the TB-only patients (95% CI: 6.2–10.8). Conclusions Our results emphasize the significance of AIDS among TB patients in Brazil, as well as the importance of evaluating secondary data in order to improve their quality and develop public health interventions.

Sexually transmitted infections during pregnancy pose a major risk to the fetus due to vertical transmission. The study's objective was to determine the prevalence of HIV, syphilis, hepatitis B and C, and HTLV-I/II infection among low-income postpartum and pregnant women treated in Greater Metropolitan Vitória, Espírito Santo State, Brazil, and the risk factors associated with these infections. A cross-sectional study was conducted from February to October 1999 assessing postpartum and pregnant women from the maternity ward of the Vitória Mercy Hospital and the Carapina Outpatient Referral Unit in the Municipality of Serra, respectively. Patients were systematically interviewed and had blood samples drawn for serological tests (HIV 1&2, VDRL, HbsAg, anti-HCV, and HTLV-I/II). A total of 534 patients (332 postpartum and 202 pregnant women) were assessed. Seroprevalence rates for the target infections in postpartum and pregnant women and the overall sample were as follows, respectively: HIV 0.9%, 0%, and 0.6%; syphilis 2.1%, 3.6%, and 2.7%; HBV 1.2%, 1%, and 1.1%; HCV 1.8%, 0.6%, and 1.4%; and HTLV-I/II 1.7%, 0.6%, and 1.3%. Factors associated with the various infections are presented and analyzed in light of other research findings from the literature. PMID:19300855

K Ar and 40Ar/39Ar ages of dikes emplaced in the onshore basement of the Santos Basin, Resende area, SE Brazil: implications for the south Atlantic opening and Tertiary reactivation  

NASA Astrophysics Data System (ADS)

New K Ar and 40Ar/39Ar data of tholeiitic and alkaline dike swarms from the onshore basement of the Santos Basin (SE Brazil) reveal Mesozoic and Tertiary magmatic pulses. The tholeiitic rocks (basalt, dolerite, and microgabbro) display high TiO2 contents (average 3.65 wt%) and comprise two magmatic groups. The NW-oriented samples of Group A have (La/Yb)N ratios between 15 and 32.3 and range in age from 192.9±2.2 to 160.9±1.9 Ma. The NNW-NNE Group B samples, with (La/Yb)N ratios between 7 and 16, range from 148.3±3 to 133.9±0.5 Ma. The alkaline rocks (syenite, trachyte, phonolite, alkaline basalts, and lamprophyre) display intermediate K contents and comprise dikes, plugs, and stocks. Ages of approximately 82 Ma were obtained for the lamprophyre dikes, 70 Ma for the syenite plutons, and 64 59 Ma for felsic dikes. Because Jurassic Early Cretaceous basic dikes have not been reported in SE Brazil, we might speculate that, during the emplacement of Group A dikes, extensional stresses were active in the region before the opening of the south Atlantic Ocean and coeval with the Karoo magmatism described in South Africa. Group B dikes yield ages compatible with those obtained for Serra Geral and Ponta Grossa magmatism in the Paraná Basin and are directly related to the breakup of western Gondwana. Alkaline magmatism is associated with several tectonic episodes that postdate the opening of the Atlantic Ocean and related to the upwelling of the Trindade plume and the generation of Tertiary basins southeast of Brazil. In the studied region, alkaline magmatism can be subdivided in two episodes: the first one represented by lamprophyre dykes of approximately 82 Ma and the second comprised of felsic alkaline stocks of approximately 70 Ma and associated dikes ranging from 64 to 59 Ma.

Leonardo da Vinci's Geometric Sketches  

NSDL National Science Digital Library

How do you solve a problem like solids, mathematically speaking? Well, you could use this rather fascinating resource provided by the Convergence magazine. Offered as an educational resource by the Mathematical Association of America (MAA), this particular resource brings together the work of the Franciscan friar Luca Pacioli (c.1445-1509) and the geometric sketches of Leonardo Da Vinci. Both men were interested in geometry, and this piece offers up a number of plate facsimiles of illustrations created by Da Vinci. Here visitors will find an introduction to this educational resource, along with illustrations of cubes, octahedrons, and cylinders. The accompanying article was written by Frank J. Swetz, and it is easy to see how these materials could be incorporated into a classroom discussion about the history of mathematics.

The potentially dangerous asteroid 2012 DA14  

NASA Astrophysics Data System (ADS)

We present computing methods that allow us to study the behaviour of the dynamically interesting potentially dangerous asteroid 2012 DA14. Using the freely available ORBFIT software, we can follow the orbit of the asteroid backward and forward in the future, searching for close approaches to the Earth that might lead to possible impacts. The possible impact orbit for 2026 is computed. We show that it should be possible to recover asteroid 2012 DA14, mainly in 2013 February. It is highly unlikely that asteroid 2012 DA14 will hit any geosynchronous satellites during its close approach on 2013 February 15.

The Overlooked H II Region DA 568  

NASA Astrophysics Data System (ADS)

During the inspection of Canadian Galactic Plane Survey 1420 MHz continuum images of the outer Galaxy we have rediscovered the large, bright, H II region DA 568. Intriguingly, this region does not appear in any of the commonly used catalogs of H II regions and radio sources in the outer Galaxy. After demonstrating how DA 568 was essentially overlooked, we present new radio, infrared, and molecular line observations of the region. We show that, far from being a minor overlooked H II region, DA 568 is actually the most prominent part of a much larger star-forming complex in the Perseus arm of our Galaxy. The complex spans ~45×20 pc, contains over 104 Msolar of ionized and molecular gas, and includes the BFS 10 H II region and numerous associated IRAS sources. The star-forming complex is apparently quite evolved with most of the original giant molecular cloud having been severely disrupted by the action of DA 568.

Situação da Mulher na Astronomia Brasileira  

NASA Astrophysics Data System (ADS)

O conteúdo desse texto surgiu de uma apresentação de mesmo título que fiz na XXXI Reunião Anual da Sociedade Astronômica Brasileira (SAB) em 2005. Esse tema foi inspirado originalmente pela minha participação no "2nd UIPAP International Conference on Women in Physics" realizado entre 23 e 25 de maio de 2005 no Rio de Janeiro. Essa é uma conferência internacional que acontece de três em três anos, sendo que a primeira ocorreu em 2002 na cidade de Paris, França. Participei dessa conferência como membro da delegação da Sociedade Brasileira de Física e um dos trabalhos que apresentei versava sobre a situação das mulheres na Astronomia brasileira, cujos resultados principais discorro a seguir. A situação das astrônomas, baseada nos dados dos sócios da SAB coletados no final de 2004, é comparada com a das físicas brasileiras e também com as nossas colegas americanas. Os dados identificam ainda uma maior evasão da carreira por parte das mulheres do que os homens. Alguns dos possíveis motivos da evasão são discutidos, como o desejo de constituir família e/ou isolamento. Resultados um tanto preocupantes com relação à distribuição de bolsas de produtividade do CNPq também são apresentados. As principais discussões e estratégias recomendadas nesse congresso são mencionadas de forma resumida ao final.

Hot White Dwarf Luminosity Function, non-DA to DA Ratio, SDSS DR7: Possible Improvements  

NASA Astrophysics Data System (ADS)

Hot white dwarf luminosity functions (LF) have opened new possibilities for the analysis of the properties of WDs at the beginning of their evolution, when the hottest and the youngest objects enter WD cooling tracks. These new LFs allow the investigation of recent star formation rate and neutrino cooling, as well as determination of the DA to non-DA ratio. The latter can, in turn, give a clue about WD atmosphere transformations and chemical composition changes in the hottest WDs. However, the number of hot WDs is rather low, leading to large errors in the DA to non-DA ratio. Is a new SDSS WD catalog a solution to the problem? Some answers are given in this short review.

The DEAR experiment on DA?NE  

NASA Astrophysics Data System (ADS)

DEAR is one of the first experiments at the new DA?NE ?-factory at the Laboratori Nazionali di Frascati dell'INFN. The objective of the DEAR experiment is to perform a precision measurement of the strong interaction shifts and widths of the K-series lines in kaonic hydrogen and the first observation of the same quantities in kaonic deuterium. The aim is to obtain a precise determination of the isospin-dependent kaon-nucleon scattering lengths which will represent a breakthrough in KN low-energy phenomenology and will allow us to determine the kaon-nucleon sigma terms. The sigma terms give a direct measurement of chiral symmetry breaking and are connected to the strangeness content of the proton. First results on background measurements with the DEAR NTP setup installed on DA?NE are reported.

The real code of leonardo da vinci.  

PubMed

Leonardo da Vinci was born in Italy. Among the researchers and scientists, he is favourably known for his remarkable efforts in scientific work. His investigations of atherosclerosis judiciously combine three separate fields of research. In 1506, he finished his masterpiece, painting of Mona Lisa. A careful clinical examination of the famous painting reveals a yellow irregular leather-like spot at the inner end of the left upper eyelid and a soft bumpy well-defined swelling of the dorsum of the right hand beneath the index finger about 3 cm long. This is probably the first case of familial hypercholesterolemia (FH). The FH code of Leonardo da Vinci was given immense consideration by scientists like Carl Muller, who described the xanthomas tuberosum and angina pectoris. On the contrary, Akira Endo searched for microbial metabolites that would inhibit HMG-CoA reductase, the rate-limiting enzyme in the synthesis of cholesterol and finally, Michael Brown and Joseph Goldstein published a remarkable series of elegant and insightful papers in the 70s and 80s. They established that the cellular uptake of low-density lipoprotein (LDL) essentially requires the LDL receptor. In conclusion: this was the real Code of Leonardo da Vinci. PMID:19924278

Locally formed dopamine modulates renal Na-Pi co-transport through DA1 and DA2 receptors.  

PubMed Central

The involvement of dopamine (DA) receptor subtypes in regulation of renal phosphate transport by DA, either exogenous or locally synthesized from L-dihydroxyphenylalanine (L-dopa) was evaluated in opossum kidney (OK) cells with proximal tubular phenotype. DA synthesis from L-dopa by OK cells was abolished by carbidopa and benserazide, two dissimilar inhibitors of aromatic L-amino acid decarboxylase. L-Dopa stimulated cyclic AMP generation and inhibited Na-dependent Pi uptake, and these effects were abolished by carbidopa and benserazide. The effects of L-dopa or DA on cyclic AMP generation and on Na-Pi co-transport were mimicked by SKF 38393, a DA1 receptor agonist, and were potentiated by S-sulpiride, a DA2 receptor antagonist. Bromocriptine, a DA2 receptor agonist, blunted in a pertussis toxin-dependent manner parathyroid hormone (PTH)-induced cyclic AMP generation and inhibition of Pi uptake. In contrast with PTH, neither L-dopa nor DA affected significantly the cytosolic calcium concentration. These results support the involvement of DA1 and DA2 receptors, positively and negatively coupled into adenylate cyclase respectively, in modulation of renal phosphate transport.

Depth asymmetry in da Vinci stereopsis.  

PubMed

We investigated processes that determine the depth localization of monocular points which have no unambiguous depth. It is known that horizontally adjacent binocular objects are used in depth localization and for a distance of 25-40 min arc monocular points localize to the leading edge of a depth constraint zone, which is an area defined by the visibility lines between which the points in the real world must be. We demonstrate that this rule is not valid in complex depth scenes. Adding other disparate objects to the scene changes the localization of the monocular point in a way that cannot be explained by the da Vinci explanation of monocular-binocular integration. The effect of additional disparate objects is asymmetric in depth: a crossed object does not affect the da Vinci effect but an uncrossed object biases the depth localization of monocular objects to uncrossed direction. We conclude that a horizontally adjacent binocular plane does not completely determine the depth localization of a monocular point and that depth spreading from other binocular elements biases the localization process.

The neuroanatomical plates of Guido da Vigevano.  

PubMed

Guido da Vigevano was an Italian physician and engineer who lived in the 13th and 14th centuries. He was the first scientist who used pictures to illustrate his anatomical descriptions, developing for the first time a close relationship between anatomical studies and artistic drawings. This was further developed in the Renaissance. In his textbook Anathomia are displayed six plates showing for the first time neuroanatomical structures and techniques: dissection of the head by means of trephination, and depictions of the meninges, cerebrum, and spinal cord. On the surface of the brain painting it is possible to recognize a vague patterning of cortical convolutions. Ventricles are also described and shown. This book constituted the first attempt in the history of neuroscience to illustrate an anatomical description with schematic pictures to achieve a better understanding of such complex structures.

Flutuações da temperatura eletrônica em NGC 2438 e NGC 2440  

NASA Astrophysics Data System (ADS)

Tradicionalmente, as abundâncias em nebulosas planetárias e regiões HII têm sido obtidas de linhas excitadas colisionalmente, as quais são fortemente dependentes da temperatura eletrônica. Alternativamente, as abundâncias químicas podem ser determinadas de linhas de recombinação, as quais são quase independententes da temperatura eletrônica. Entretanto, consideráveis diferenças têm sido encontradas entre estes dois métodos. Estas discrepâncias têm sido atribuídas às flutuações espaciais da temperatura eletrônica. Entretanto, as magnitudes necessárias de flutuações de temperatura eletrônica são consideravelmente mais altas do que aquelas preditas pelos modelos padrões de fotoionização e os mecânismos físicos que poderiam explicar as grandes flutuações de temperatura são desconhecidas. Desta forma, o estudo de variações da temperatura eletrônica em regiões HII e nebulosas planetárias tem ganho um renovado interesse. Neste trabalho apresentamos os resultados preliminares de um estudo observacional sobre variações internas da temperatura eletrônica nas nebulosas planetárias NGC 2440 e NGC 2438. Analisamos dados espectrofotométricos de fenda longa, com alta razão sinal-ruído, na faixa de 3300-6800 Å, com o espectrógrafo Cassegrain Boller & Chivens acoplado ao telescópio de 1.52 m do European Southern Observatory (ESO). Temperaturas eletrônicas foram derivadas da razão [OIII](l4959+l5007)/l4363 em diferentes posições em cada nebulosa planetária. Flutuações da temperatura eletrônica foram detectadas e suas magnitudes foram estimadas em NGC 2440 e NGC 2438.

Circumstellar features in hot DA white dwarfs  

NASA Astrophysics Data System (ADS)

We present a phenomenological study of highly ionized, non-photospheric absorption features in high spectral resolution vacuum ultraviolet spectra of 23 hot DA white dwarfs. Prior to this study, four of the survey objects (Feige 24, REJ 0457-281, G191-B2B and REJ 1614-085) were known to possess these features. We find four new objects with multiple components in one or more of the principal resonance lines: REJ 1738+665, Ton 021, REJ 0558-373 and WD 2218+706. A fifth object, REJ 2156-546, also shows some evidence of multiple components, though further observations are required to confirm the detection. We discuss possible origins for these features including ionization of the local interstellar environment, the presence of material inside the gravitational well of the white dwarf, mass loss in a stellar wind and the existence of material in an ancient planetary nebula around the star. We propose ionization of the local interstellar medium as the origin of these features in G191-B2B and REJ 1738+665, and demonstrate the need for higher-resolution spectroscopy of the sample, to detect multiple interstellar medium velocity components and to identify circumstellar features that may lie close to the photospheric velocity.

[The pharmacokinetic effect of haloperidol on DA receptors].  

PubMed

There is increasing evidence that the metabolism of haloperidol is of major significance in the action of the drug. The metabolism of haloperidol is quite simple. It keeps only typical oxidative metabolic pathway. Despite of the existing knowledge of such pathways we still do not know the exact fate of the administered compound in the serum and urine. The aim of the study was the investigation of the influence of haloperidol and its oxidative forms on D(A) and its compounds in serum. The 12,0 hour investigation demonstrated a protective effect on D(A) activity. The D(A) synthesis rate constant was increased to about the same level by GBL as well as by haloperidol. Therefore, the differences between the two regions in the reactions to the drugs to a large extent could be explained by a high and low synthesis of D(A), under controlled conditions in the olfactory tubercle and the corpus striatum.

Estudo de não gaussianidade nas anisotropias da RCF medidas Wmap  

NASA Astrophysics Data System (ADS)

A investigação do campo de flutuações da Radiação Cósmica de Fundo (RCF) pode oferecer um importante teste para os modelos cosmológicos que descrevem a origem e a evolução das flutuações primordiais. De um lado, apresenta-se o modelo inflacionário que prevê um espectro de flutuações adiabáticas distribuídas segundo uma gaussiana e, de outro, os modelos de defeitos topológicos (dentre outros) que descrevem um mecanismo para a geração de flutuações de isocurvatura que obedecem a uma distribuição não gaussiana. Este trabalho tem como objetivo caracterizar traços do modelo não gaussiano de campo misto (entre flutuações adiabáticas e de isocurvatura) nos mapas do Wilkinson Microwave Anisotropy Probe (WMAP). Simulações das anisotropias da RCF no contexto de mistura indicam traços marcantes na distribuição das flutuações de temperatura, mesmo quando consideradas pequenas contribuições do campo de isocurvatura (da ordem de 0.001). O efeito da mistura entre os campos resulta na transferência de potência de flutuações em escalas angulares intermediárias para flutuações em pequenas escalas angulares. Este efeito pode ser caracterizado pela relação entre as amplitudes dos primeiros picos acústicos no espectro de potência da RCF. Neste trabalho, investigamos a contribuição do campo de isocurvatura, no contexto de mistura, sobre as observações recentes da RCF realizadas pelo WMAP. As previsões do modelo de campo misto, uma vez confrontadas com as observações em pequenas escalas angulares, podem ajudar a revelar a natureza das flutuações primordiais.

Mevalocidin: a novel, phloem mobile phytotoxin from Fusarium DA056446 and Rosellinia DA092917.  

PubMed

A multiyear effort to identify new natural products was built on a hypothesis that both phytotoxins from plant pathogens and antimicrobial compounds might demonstrate herbicidal activity. The discovery of one such compound, mevalocidin, is described in the current report. Mevalocidin was discovered from static cultures of two unrelated fungal isolates designated Rosellinia DA092917 and Fusarium DA056446. The chemical structure was confirmed by independent synthesis. Mevalocidin demonstrated broad spectrum post-emergence activity on grasses and broadleaves and produced a unique set of visual symptoms on treated plants suggesting a novel mode of action. Mevalocidin was rapidly absorbed in a representative grass and broadleaf plant. Translocation occurred from the treated leaf to other plant parts including roots confirming phloem as well as xylem mobility. By 24 hr after application, over 20 % had been redistributed through-out the plant. Mevalocidin is a unique phytotoxin based on its chemistry, with the uncommon attribute of demonstrating both xylem and phloem mobility in grass and broadleaf plants. PMID:23314893

Overview of ATLAS PanDA Workload Management  

SciTech Connect

The Production and Distributed Analysis System (PanDA) plays a key role in the ATLAS distributed computing infrastructure. All ATLAS Monte-Carlo simulation and data reprocessing jobs pass through the PanDA system. We will describe how PanDA manages job execution on the grid using dynamic resource estimation and data replication together with intelligent brokerage in order to meet the scaling and automation requirements of ATLAS distributed computing. PanDA is also the primary ATLAS system for processing user and group analysis jobs, bringing further requirements for quick, flexible adaptation to the rapidly evolving analysis use cases of the early datataking phase, in addition to the high reliability, robustness and usability needed to provide efficient and transparent utilization of the grid for analysis users. We will describe how PanDA meets ATLAS requirements, the evolution of the system in light of operational experience, how the system has performed during the first LHC data-taking phase and plans for the future.

V3885 Sgr é uma variável cataclísmica classificada como sendo do tipo nova-like. É apresentado um estudo espectrofotométrico de V3885 Sgr de alta resolução temporal feito na região do visível. A região observada é centrada em Ha e abrange também a linha de HeI 6678. O primeiro resultado obtido neste estudo é a determinação do período orbital a partir de medidas da velocidade radial da linha de Ha como sendo 0,20716071(22) dias, resolvendo inconsistências quanto a esse valor na literatura e definindo uma efeméride a longo prazo para o sistema. Com este período e as medidas de velocidade radial do perfil de linha de Ha foi construído um diagrama de massas, através do qual restringimos as massas das componentes estelares do sistema e limitamos a inclinação orbital do sistema. Foram construídos diagramas de Greenstein para as linhas de Ha e HeI, onde os espectros médios em cada intervalo de fase são representados lado a lado em escala de cinza, indicando a existência de uma emissão intensa proveniente da parte posterior do disco. A partir da tomografia Doppler obtivemos perfis de emissividade radial para o disco tanto para a linha de Ha como para HeI. Os resultados obtidos são comparados com os de outros sistemas estudados com a mesma técnica. Serão apresentados também resultados da tomografia de flickering para o sistema.

The Potential da Vinci in All of Us  

NSDL National Science Digital Library

The study of the human form is fundamental to both science and art curricula. For vertebrates, perhaps no feature is more important than the skeleton to determine observable form and function. As Leonard da Vinci's famous Proportions of the Human Figure (Virtruvian Man) illustrates, the size, shape, and proportions of the human body are defined by bones and their articulations. In this unit that focuses on the human skeleton, students are introduced to these concepts by asking them both to study da Vinci's drawing and build their own model of the human skeleton. Units on animal camouflage and architecture are also presented to further support the art and science connection.

The Near-Earth Flyby of Asteroid 2012 DA14  

NASA Astrophysics Data System (ADS)

On UT 2013 February 15, the approximately 30 meter near-Earth asteroid 2012 DA14 made a close flyby of the Earth at a distance of approximately 27,000 km or 4 Earth-radii. This passage was inside the orbital distance of geosynchronous satellites and close to the Earth’s Roche limit. This close encounter was unprecedented in our advance knowledge of the incoming trajectory, thereby allowing us to forge a detailed coordinated plan for observation and testing of physical models predicting tidal effects near our planet’s Roche limit. Predicted outcomes of such close encounters include tidal disruption, changes in rotation state, and mass loss or mass redistribution due to seismic shaking. Each of these effects sensitively depend on how tidal energy is dissipated in the interior of the asteroid: a rubble pile will dissipate tidal energy differently than a solid or partially fractured monolith. The internal properties of asteroids in general and particularly those in the size range of 2012 DA14 are largely unknown. This encounter represents one of the first ever opportunities to observationally test models of the interior structure of small planetary bodies. We will present the results of a large multi-observatory campaign that obtained visible-wavelength photometric and spectroscopic observations of 2012 DA14 during its discovery epoch in 2012, and surrounding its close approach in 2013. These results include clear evidence that 2012 DA14 is now in a non-principal axis rotation state, requiring a multi-periodic tumbling model to fit its post-flyby rotational light curve. The ultimate goal of this campaign will be to investigate changes to 2012 DA14’s physical properties induced by its gravitational interactions with the Earth.

Yarkovsky-driven Impact Predictions: Apophis and 1950 DA  

NASA Astrophysics Data System (ADS)

Orbit determination for Near-Earth Asteroids presents unique technical challenges due to the imperative of early detection and careful assessment of the risk posed by specific Earth close approaches. The occurrence of an Earth impact can be decisively driven by the Yarkovsky effect, which is the most important nongravitational perturbation as it causes asteroids to undergo a secular variation in semimajor axis resulting in a quadratic effect in anomaly. We discuss the cases of (99942) Apophis and (29075) 1950 DA. The relevance of the Yarkovsky effect for Apophis is due to a scattering close approach in 2029 with minimum geocentric distance ~38000 km. For 1950 DA the influence of the Yarkovsky effect in 2880 is due to the long time interval preceding the impact. We use the available information from the astrometry and the asteroids' physical models and dynamical evolution as a starting point for a Monte Carlo method that allows us to measure how the Yarkovsky effect affects orbital predictions. We also find that 1950 DA has a 98% likelihood of being a retrograde rotator. For Apophis we map onto the 2029 close approach b-plane and analyze the keyholes corresponding to resonant close approaches. For 1950 DA we use the b-plane corresponding to the possible impact in 2880. We finally compute the impact probability from the mapped probability density function on the considered b-plane. For Apophis we have 4 in a million chances of an impact in 2068, while the probability of Earth impact in 2880 for 1950 DA is 0.04%.

The isolated massive DA white dwarf GD 50  

SciTech Connect

Analysis of accurate hydrogen line profiles from optical and ultraviolet spectrophotometry shows that the hot DA white dwarf GD 50 (WD 0346-011) has an exceptionally high surface gravity of log g = 9.0 + or - 0.15; the derived parameters imply a mass of 1.2 solar mass and a radius of 0.0057 solar mass, if an interior composed of carbon and oxygen is assumed. As such, it is the first well-studied, isolated DA white dwarf with a likely mass larger than that of Sirius B. Moreover, the derived mass is large enough to consider the possibility that the interior is composed of oxygen, neon, and magnesium. If GD 50 has evolved as a single object, it should be quite young. Alternatively, the star could have formed as the result of a merger of a close pair of white dwarfs. 48 refs.

[Giovanbattista da Monte (Montanus): father of modern clinical medicine].  

PubMed

The figure of Giovanbattista da Monte (1489-1551) is associated with the introduction of clinical teaching at the patient's beside, in 1543, at the San Francesco Hospital of Padua. In the XVI century, teaching was still based on the explanation and comment of the ancient authors and the educational programme was founded on theoretical aspects. The "practical" approach consisted of the treatment "ex cathedra" of diseases according to the various parts of the body, without observing the course of the pathological events with a direct confirmation at the patient's beside.To his merit, Da Monte established the practise of training students to gather the case history, to carry out an objective examination, and to closely examine disease phenomena with lessons at the bedside of the patient. Practical clinical training was thus introduced as the crucial moment in the formation of the physician. PMID:16285087

Improving Security in the ATLAS PanDA System  

NASA Astrophysics Data System (ADS)

The security challenges faced by users of the grid are considerably different to those faced in previous environments. The adoption of pilot jobs systems by LHC experiments has mitigated many of the problems associated with the inhomogeneities found on the grid and has greatly improved job reliability; however, pilot jobs systems themselves must then address many security issues, including the execution of multiple users' code under a common 'grid' identity. In this paper we describe the improvements and evolution of the security model in the ATLAS PanDA (Production and Distributed Analysis) system. We describe the security in the PanDA server which is in place to ensure that only authorized members of the VO are allowed to submit work into the system and that jobs are properly audited and monitored. We discuss the security in place between the pilot code itself and the PanDA server, ensuring that only properly authenticated workload is delivered to the pilot for execution. When the code to be executed is from a 'normal' ATLAS user, as opposed to the production system or other privileged actor, then the pilot may use an EGEE developed identity switching tool called gLExec. This changes the grid proxy available to the job and also switches the UNIX user identity to protect the privileges of the pilot code proxy. We describe the problems in using this system and how they are overcome. Finally, we discuss security drills which have been run using PanDA and show how these improved our operational security procedures.

Stroemgren photometry of ZZ Ceti and other DA white dwarfs  

SciTech Connect

Stroemgren colors for a sample of 71 stars classified as DA white dwarfs are presented. Comparison with the recent model atmospheres of the Kiel group indicates that the average gravity of 63 stars of the sample is log g = 7.98 +- 0.31, with no indication of a dependence on the effective temperature. This is consistent with the theoretical expectation that white dwarfs evolve at constant gravity. Correlations between Stroemgren colors and Greenstein multichannel colors are also given, using 52 stars that have been observed in common in the two systems. These correlations are used to compare the data with a second set of model atmospheres computed by Shipman. Contrary to what has been suggested in the past, no fundamental differences are found when confronting the Stroemgren data with the DA model atmospheres of Shipman or those of the Kiel group. Finally, observations of 11 pulsating objects reveal the existence of a narrow instability strip in the range 13 000 K> or approx. =T/sub e/> or approx. =11 000 K in a ((u-b), (b-y)) two-color diagram. The present results add evidence to the contention that all DA white dwarfs evolve to become ZZ Ceti pulsators in the instability strip.

Characterization of a dopamine receptor (DA sub 2K ) in the kidney inner medulla  

SciTech Connect

Dopamine (DA) produces a natriuretic/diuretic response in the kidney by mechanisms that are still not well understood. There is some indication that DA{sub 2} receptors may be involved in mediating the effects of DA, but little is known regarding the nature of this receptor in the kidney. Autoradiographic localization of ({sup 3}H)spiperone, a DA{sub 2} antagonist, indicated that high-density binding was restricted to inner medullary collecting ducts (IMCDs). ({sup 3}H)Spiperone binding was saturable, high affinity and high density. Functionally, DA stimulated prostaglandin E{sub 2} production by IMCD cells, an effect that could be blocked by the DA{sub 2} antagonist domperidone. These results indicate that the kidney inner medulla expresses a functional DA receptor that may represent a newly identified DA receptor subtype (here designated DA{sub 2K}). Moreover, these results suggest that the kidney inner medulla may be a significant site at which DA, either directly or indirectly, influences water and electrolyte excretion.

In the drawing of coitus by Leonardo da Vinci are pictured the contemporary hypotheses regarding this act. The authors analyze the mamillaruteral connection depicted by the artist and grow up to believe that this is a hypothetical kiveris vena, female vein described by Anatomist Master Nicolai Physicus from the Salerno School. The Hebrew roots were found in the name. The connection is described also by Mondino in The Anathomia. The same connection can be found in the picture of the pregnant woman in Fasciculus Medicinæ by Johannes De Ketham. PMID:23391978

Da Vinci's codex and the anatomy of healthcare.  

PubMed

We usually display a laid-back approach to medical jargon throughout our theatre work. The word 'perioperative' is built from the Greek word 'peri' (around) and the Latin 'operari' (to work). Latin and Greek became the prefixed language of choice for Leonardo da Vinci, and his research was pivotal in determining the way in which surgical procedures are documented. Ancient manuscripts aided the unfolding of the secrets of anatomy, and Leonardo revealed that art was the key in expressive detailed explanation. PMID:23248927

We report on recent results from a high-resolution spectroscopic survey of hot DA white dwarfs, based on IUE, FUSE and HST observations. For the first time, we address the measurement of element abundances in a completely objective manner with a spectroscopic model fitting technique, which allows us to consider formally the limits that can be placed on abundances in stars where no heavy elements are detected. We also include our latest analysis of the high resolution EUV spectrum of G191-B2B recorded by J-PEX.

Engineered zinc-finger nucleases (ZFNs) enable targeted genome modification. Here we describe Context-Dependent Assembly (CoDA), a platform for engineering ZFNs using only standard cloning techniques or custom DNA synthesis. Using CoDA ZFNs, we rapidly altered 20 genes in zebrafish, Arabidopsis, and soybean. The simplicity and efficacy of CoDA will enable broad adoption of ZFN technology and make possible large-scale projects focused on multi-gene pathways or genome-wide alterations.

Identification of sequence similarity between 60 kDa and 70 kDa molecular chaperones: evidence for a common evolutionary background?  

PubMed Central

Recent findings support the premise that chaperonins (60 kDa stress-proteins) and alpha-subunits of F-type ATPases (alpha-ATPase) are evolutionary related protein families. Two-dimensional gel patterns of synthesized proteins in unstressed and heat-shocked embryonic Drosophila melanogaster SL2 cells revealed that antibodies raised against the alpha-subunit of the F1-ATPase complex from rat liver recognize an inducible p71 member of the 70 kDa stress-responsive protein family. Molecular recognition of this stress-responsive 70 kDa protein by antibodies raised against the F1-ATPase alpha-subunit suggests the possibility of partial sequence similarity within these ATP-binding protein families. A multiple sequence alignment between alpha-ATPases and 60 kDa and 70 kDa molecular chaperones is presented. Statistical evaluation of sequence similarity reveals a significant degree of sequence conservation within the three protein families. The finding suggests a common evolutionary origin for the ATPases and molecular chaperone protein families of 60 kDa and 70 kDa, despite the lack of obvious structural resemblance between them.

[Textual Research on Chiding Disease and Matixiang Herb in Da he wai ke (External Medicine of Da He)].  

PubMed

Recorded in Da he wai ke (The External Medicine of Da He) in the Ming dynasty without a corresponding disease title in contemporary scholarly concepts of Traditional Chinese Medicine (TCM), Chiding disease was described as an acute symptomatic disease with inevitable serious conditions of convulsion-like or mania-like behavior, and as a refractory ailment. It was also considered as an alias of Hongsiding (namely the acute lymphangitis) in few ancient books. Matixiang, a Chinese herb for treatment of Chiding, was regarded as a nonsuch drug by Da he wai ke, and was considered as a take-then-cure drug by Chuang yang jing yan quan shu (Compendium for Experience in Sores Diseases). The present studies about Chiding and Matixiang show that: (1) the name of Chiding was first seen in Zhong zang jing (Master Hua's Classic of the Viscera) ; (2) Chiding was rarely mentioned in medical literature of the Song, Yuan and Qing Dynasty, but mostly seen in the Ming Dynasty; (3) Xinding and Huoyanding were found as synonyms of Chiding ; (4) the distinction between Chiding and Hongsiding (flaming sore) was revealed by comparison analysis of their etiology, affected part(s), symptoms, prognosis and syndromic pictures; (5) Chiding on the tongue is the same as "Tongue Ding" or "Sublingual Ding" in contemporary TCM and as "Sublingual Space Infection" in Western Medicine. Moreover, Chiding on the hands, feet or other skin parts could be classified as "Hands/Feet Ding" in contemporary TCM and as "Furuncle" (i.e., Acute Suppurative Folliculitis and Perifolliculitis or cellulites of the tongue) in Western Medicine; (6) Matixiang is probably deduced as Asarum forbesii Maxim., A. ichangense C. Y. Cheng et C. S. Yang, family Aristolochiaceae, or Valeriana jatamansi Jones., family Valerianaceae. PMID:23363849

Groundwater Resources of Ribeira Paul Basin, Island of Santo Antao, Cape Verde, West Africa  

USGS Publications Warehouse

Groundwater resources in Cape Verde provide water for agriculture, industry, and human consumption. These resources are limited and susceptible to contamination. Additional groundwater resources are needed for continued agricultural development, particularly during times of drought, but increased use and (or) climatic change may have adverse effects on the quantity and quality of freshwater available. In volcanic island aquifers such as those of Cape Verde, a lens of fresh groundwater typically ?floats? upon a layer of brackish water at the freshwater/saltwater boundary, and increased pumping may cause salt water intrusion or other contamination. A recent U.S. Geological Survey study assessed baseline groundwater conditions in watersheds on three islands of Cape Verde to provide the scientific basis for sustainably developing water resources and minimizing future groundwater depletion and contamination.

Is the 32-kDa fragment the functional enamelin unit in all species?  

PubMed

Enamelin is an extracellular enamel matrix protein essential for normal amelogenesis. After secretion, porcine enamelin is processed to generate several enamelin-degradation products. The cumulative 32-kDa enamelin is the most abundant enamelin present, and various roles for this molecule have been suggested. However, the proteolytic cleavage sites in porcine enamelin that generate the 32-kDa enamelin are not conserved across species, and the 32-kDa enamelin analogue may not be present in all species. To explore this we studied rat enamelin biochemistry using western blotting with anti-peptide IgGs to porcine 32-kDa enamelin and to the putative rat 32-kDa enamelin analogue. The dominant enamelins in secretory-stage rat enamel migrated at around 60-70 kDa. In contrast, the dominant enamelins in secretory-stage porcine enamel migrated at around 32 kDa. In contrast, secretory-stage porcine-enamel enamelins were dominated by the 32-kDa enamelin. Rat enamelin was completely removed from maturation-stage enamel without any accumulation of 32-kDa enamelin. We suggest that a discrete 32-kDa enamelin is not essential for normal amelogenesis in all species, and in pig it may be a processing product of a larger functional enamelin molecule. The pig may be an atypical model in terms of enamelin biochemistry and function, and caution should be exercised when assigning functional roles to the 32-kDa enamelin as a discrete enamel matrix entity.

Purification and characterization of a 7-kDa protein from Clonorchis sinensis adult worms.  

PubMed

A 7-kDa protein was purified from extracts of adult Clonorchis sinensis by a combination of ammonium sulfate precipitation, anion exchange chromatography, cation exchange chromatography, gel-filtration chromatography, and reversed-phase FPLC. The 7-kDa protein exists in the excretory-secretory products of adult C. sinensis, but not in extracts of adult Paragonimus westermani. Also, the 7-kDa protein reacted with the sera of patients with clonorchiasis but not with paragonimiasis or normal human sera. To observe the localization of the 7-kDa protein in the tissue of adult C. sinensis, an immunogold labeling method was followed using anti-7-kDa antibody. The gold particles were observed in the basal layer below the tegumental syncytium, in the interstitial matrix of the parenchyma, and in the content of the uterus. The 7-kDa cDNA was obtained through reverse transcription-polymerase chain reaction using a primer designed from N-terminal sequence analysis. Rapid amplification of cDNA ends (5'-RACE) was used to obtain the complete protein coding sequence. The sequence encodes a 90-amino acid polypeptide. The deduced amino acid sequence of the 7-kDa protein revealed no homology with proteins of different organisms reported so far. These results suggest that the 7-kDa protein is a fluid antigen and may be valuable as a tool for the immunodiagnosis of clonorchiasis. PMID:12099418

Tuning PEG-DA hydrogel properties via solvent-induced phase separation (SIPS)†  

PubMed Central

Poly(ethylene glycol) diacrylate (PEG-DA) hydrogels are widely utilized to probe cell-material interactions and ultimately for a material-guided approach to tissue regeneration. In this study, PEG-DA hydrogels were fabricated via solvent-induced phase separation (SIPS) to obtain hydrogels with a broader range of tunable physical properties including morphology (e.g. porosity), swelling and modulus (G?). In contrast to conventional PEG-DA hydrogels prepared from an aqueous precursor solution, the reported SIPS protocol utilized a dichloromethane (DCM) precursor solution which was sequentially photopolymerized, dried and hydrated. Physical properties were further tailored by varying the PEG-DA wt% concentration (5 wt%–25 wt%) and Mn (3.4k and 6k g mol ?1). SIPS produced PEG-DA hydrogels with a macroporous morphology as well as increased G? values versus the corresponding conventional PEG-DA hydrogels. Notably, since the total swelling was not significantly changed versus the corresponding conventional PEG-DA hydrogels, pairs or series of hydrogels represent scaffolds in which morphology and hydration or G? and hydration are uncoupled. In addition, PEG-DA hydrogels prepared via SIPS exhibited enhanced degradation rates.

[Initial experience with da Vinci robotic system in vascular surgery].  

PubMed

Robotic operational systems improve accuracy, control of and skilful management of surgical procedures up to levels unachievable by a human factor itself. A surgeon is also allowed to conduct the types of miniinvasive procedures, which cannot be conducted using contemporary technologies. High degree of the procedure's safety can be achieved. Currently, the robotic surgical systems are used in top clinics worldwide and the concept of the robotic operating theatre is considered to become standard for some procedures in future. In October 2005, a multispecialist robotic centre was opened in the Hospital Na Homolce, which then created a new qualitative standard in the miniinvasive surgical management. The authors present the initial group of patients, who were operated from November 2005 to January 2006 with employement of the da Vinci robotic system, listing its pros and cons. PMID:16805339

3D Model Atmospheres of DA White Dwarfs  

NASA Astrophysics Data System (ADS)

The spectroscopically determined surface gravities of cool hydrogen-atmosphere DA white dwarfs are significantly higher than the mean value of log g ˜ 8 found for hotter objects with radiative atmospheres (Teff > 13000 K). It was recently suggested that a problem with the treatment of convective energy transport in the 1D mixing-length theory was the explanation for this high-log g problem. We have now computed a grid of pure-hydrogen 3D model atmospheres with the CO5BOLD code for surface gravities from log g = 7 to 8.5 and effective temperatures from 6000 to 13000 K. Over this range, the intensity contrast of the surface granulation pattern, which describes the strength of the 3D effects, is varying significantly. We confirm the result of an earlier investigation that 3D model spectra provide a much better characterization of the mass distribution of cool white dwarfs.

Search for Metal Pollution in 81 DA White Dwarfs  

NASA Astrophysics Data System (ADS)

A total of 82 DA white dwarfs have been observed with the Cosmic Origins Spectrograph on the Hubble Space Telescope in a snapshot program. The targets were selected to be in the Teff range from 17 000 - 25 000 K, where optical metal lines become weak and difficult to detect. Because of the strong Si, C, and O resonance lines in the UV, this survey has a sensitivity that is comparable to that of the Keck/VLT searches for CaII K in cooler white dwarfs. These objects also have no convection zone and thus very short diffusion timescales, assuring that accretion is currently ongoing. The spectra have high resolution and in most cases fairly good S/N. About 60% of them show photospheric metal pollution, predominantly of Si, but in some cases additional metals are present. We report the results of a preliminary analysis and discuss the sources of the accreted matter and the possible rôle of radiative levitation.

DBS -- An rlogin multiplexer and output logger for DA systems  

SciTech Connect

DART Bootstrap Services (dbs) is the first component of run-control for the DART Data Acquisition system -- the DA for the 96` round of experiments at Fermilab -- though it has potential usefulness as a powerful tool in other distributed applications. dbs is an rlogin session multiplexer. It allows a user, running a single program, to start up any number of remote login sessions, feed shell commands to them, and collect their output into a single (or multiple) log files (a server keeps the sessions open and collects their output). From this program, any session can be attached to interactively so it appears just like an rlogin session -- dbs becomes transparent. When finished with this interactive mode, the user can escape back to dbs and attach to a different session if so desired. Among many other useful features, dbs supplies a mechanism for cleanup (deletion) of all processes created under a session, allowing a fresh start.

Xanthelasma and lipoma in Leonardo da Vinci's Mona Lisa.  

PubMed

The painting Mona Lisa in the Louvre, Paris, by Leonardo da Vinci (1503-1506), shows skin alterations at the inner end of the left upper eyelid similar to xanthelasma, and a swelling of the dorsum of the right hand suggestive of a subcutaneous lipoma. These findings in a 25-30 year old woman, who died at the age of 37, may be indicative of essential hyperlipidemia, a strong risk factor for ischemic heart disease in middle age. As far as is known, this portrait of Mona Lisa painted in 1506 is the first evidence that xanthelasma and lipoma were prevalent in the sixteenth century, long before the first description by Addison and Gall in 1851.

Extreme Lyman ? Broadening in Cool DA and DC White Dwarfs  

NASA Astrophysics Data System (ADS)

We model the far red wing of the Lyman ? line of hydrogen in the atmospheres of cool white dwarfs of pure hydrogen composition. We find that this absorption process dominates all other sources of opacity in the blue part of the optical spectrum. Our successful fit of the entire spectral energy distribution of the cool DA BPM 4729 shows that the far red wing of the Ly ? line is the source of opacity that had been missing in the models. The observed sequence of cool white dwarfs in color-color diagrams is very well reproduced by our new pure hydrogen atmosphere models, suggesting that the atmospheric composition of the coolest DC white dwarfs must be revisited.

Discovery of Photospheric Germanium in Hot DA White Dwarfs  

NASA Astrophysics Data System (ADS)

We report the identification of Ge IV resonance lines in ultraviolet spectra of the hot DA white dwarfs Feige 24, G191-B2B, and GD 246. The lines originate in the stellar photosphere, and we measure low Ge/H abundance ratios ranging between -8.0 and -8.7. We also tentatively identify a resonance line of Sn IV blended with an Fe V line in the spectrum of G191-B2B. The presence of germanium extends our knowledge of the abundance pattern in hot white dwarfs beyond the iron group. The abundance ratio appears nearly solar, which implies either that the germanium abundance mixture in these stars has remained unaltered since leaving the main sequence or that diffusion processes (e.g., selective radiation pressure) are coincidentally reproducing a solar Ge/H ratio.

Heavy-element abundance patterns in hot DA white dwarfs  

NASA Astrophysics Data System (ADS)

We present a series of systematic abundance measurements for 25 hot DA white dwarfs in the temperature range ~20 000-110 000 K, based on far-ultraviolet spectroscopy with the Space Telescope Imaging Spectrograph (STIS)/Goddard High Resolution Spectrograph (GHRS) on-board Hubble Space Telescope, IUE and FUSE. Using our latest heavy-element blanketed non-local thermodynamic equilibrium (non-LTE) stellar atmosphere calculations we have addressed the heavy-element abundance patterns, making completely objective measurements of abundance values and upper limits using a ?2 fitting technique to determine the uncertainties in the abundance measurements, which can be related to the formal upper limits in those stars where particular elements are not detected. We find that the presence or absence of heavy elements in the hot DA white dwarfs largely reflects what would be expected if radiative levitation is the supporting mechanism, although the measured abundances do not match the predicted values very well, as reported by other authors in the past. Almost all stars hotter than ~50 000 K contain heavy elements. For most of these the spread in element abundances is quite narrow and similar to the abundances measured in G191-B2B. However, there is an unexplained dichotomy at lower temperatures with some stars having apparently pure H envelopes and others having detectable quantities of heavy elements. The heavy elements present in these cooler stars are often stratified, lying in the outermost layers of the envelope. A few strong temperature/evolutionary effects are seen in the abundance measurements. There is a decreasing Si abundance with temperature, the N abundance pattern splits into two groups at lower temperature and there is a sharp decline in Fe and Ni abundance to zero, below ~50 000 K. When detected, the Fe and Ni abundances maintain an approximately constant ratio, close to the cosmic value of ~20. For the hottest white dwarfs observed by STIS, the strongest determinant of abundance appears to be gravity.

Spatial analysis of schistosomiasis human cases in the horticultural community of Zona da Mata of Pernambuco state, Brazil.  

PubMed

The objective of this study was to describe the spatial distribution of schistosomiasis in horticultural community of Natuba, district of Vitória de Santo Antão, Pernambuco state. It was conducted a parasitological survey, examined the fecal material of 310 community residents. The cases positive for Schistosoma mansoni were geocoded and included in the computerized template of the community, generating maps of spatial distribution with kernel estimators. The results showed a high prevalence of schistosomiasis, with 28.4% of the parasites. Other parasites were found in 25.8% of the population. The use of GIS tools to map and understand the possible distribution of cases of schistosomiasis in the space occupied by the community highlighting and listing locations of lower elevation (able to flooding), with a higher frequency of human cases. Studies like this provide information to the local health services, may intervene and bring about change for individuals living in areas with low housing conditions to minimize their exposure to risk of contracting schistosomiasis.

A estabilidade dos PAHS em função da energia da radiação interestelar nas faixas UV e raios-X  

NASA Astrophysics Data System (ADS)

A nebulosa CRL 618, uma proto-nebulosa planetária cuja nuvem molecular espessa envolve uma estrela B0, contém uma grande quantidade de C2H2 e CH4. Estas moléculas são consideradas os tijolos da criação de grandes moléculas carbonadas como os Hidrocarbonetos Policíclicos Aromáticos (PAHs). Esta nebulosa, por estar exposta a intensos campos de UV e Raios-X, é uma região de fotodissociação molecular que propicia a formação de novas moléculas, confirmada pela presença de C4H2 e C6H6 (Benzeno), que é a unidade básica dos PAHs. Atribui-se a esta família de moléculas orgânicas duas propriedades fundamentais, a resistência para sobreviver ao campo de radiação UV interestelar e a geração das bandas de emissão não identificadas (UIR) observadas no infravermelho. No entanto, alguns autores questionam a resistência dos PAHs ao campo de radiação UV interestelar. Empregando a técnica de Espectrometria de Massas por Tempo de Vôo, no modo de coincidência fotoelétron-fotoíon, estudamos a ionização e fragmentação das seguintes moléculas: Benzeno, Benzeno deuterado, Naftaleno, Antraceno e Fenantreno. Utilizamos uma fonte de Hélio monocromática em 21,21 eV (584,5 Å) e a radiação Síncroton do Laboratório Nacional de Luz Síncroton (LNLS) em diferentes energias nas proximidades da borda do C 1s ( 290 eV). Comprovamos a estabilidade dos PAHs sob ação de UV (21,21 eV), onde eles apresentam um baixo nível de fotodissociação, produzindo fragmentos ionizados com rendimento total na ordem de 5 por cento em relação ao íon molecular pai. Entretanto, em altas energias, na faixa de Raios-X, a quebra destas moléculas torna-se mais intensa, com a produção de muitos fragmentos. Como uma das rotas de fragmentação do Naftaleno é [(C10H8) = > (C6H6+) + (C4H2) + (e-)], e como temos as evidências observacionais da existência do C4H2 e C6H6 na nebulosa CRL 618, sugerimos que este ambiente também possui o Naftaleno.

A distância e o conteúdo estelar da região HII gigante G333.1-0.4 - vínculos para a taxa de formação estelar da galáxia  

NASA Astrophysics Data System (ADS)

Neste trabalho apresentamos imagens de alta resolução angular da região HII gigante G333.1-0.4 obtidas através dos filtros J, H e K no telescópio de 4-m do CTIO. Este trabalho faz parte de um estudo de regiões HII gigantes no infravermelho próximo que tem por objetivo estudar a natureza da formação de estrelas massivas e traçar a estrutura espiral de nossa galáxia. Nossa determinação da distância é baseada no método da paralaxe espectroscópica de estrelas OB localizadas na seqüência principal de idade zero (ZAMS) do Diagrama HR. No caso de G333.1-0.4, a magnitude aparente das estrelas localizadas na ZAMS indica que a distância não pode ser maior do que o limite inferior determinado por técnica rádio (2,8 kpc). Resultados semelhantes foram encontrados para regiões estudadas anteriormente, reforçando a idéia de que a taxa de formação estelar na Via Láctea é menor do que o determinado a partir de dados rádio. Nossos resultados mais recentes sobre o conteúdo estelar de G333.1-0.4 revelaram vários objetos que possuem cores bastante avermelhadas (H-K > 2,0). Nós identificamos estes objetos usando os diagramas cor-cor e cor-magnitude dos aglomerados. Estes objetos apresentam um forte excesso em emissão na banda K e possivelmente se tratam de estrelas do tipo OB envolvidas por um disco/envelope circumestelar espesso. O estudo da função de massa inical desta região, em conjunto com resultados de nossos trabalhos anteriores, aponta para uma IMF independente da posição galática. A contagem de estrelas nos fornece um valor para o número de fótons no contínuo de Lyman que corrobora com a afirmação de que G333.1-0.4 se encontra mais próxima da menor distância determinada por rádio.

Duration of Shh signaling contributes to mDA neuron diversity.  

PubMed

Sonic hedgehog (Shh) signaling is critical for various developmental processes including specification of the midbrain dopamine (mDA) neurons in the ventral mesencephalon (vMes). While the timing of Shh and its response gene Gli1 segregates mDA neurons, their overall lineage contribution to mDA neurons heavily overlaps. Here, we demonstrate that the same set of mDA neuron progenitors sequentially respond to Shh signaling (Gli1 expression), induce Shh expression, and then turn off Shh responsiveness. Thus, at any given developmental stage, cells rarely co-express Shh and Gli1. Using Shh(Cre:GFP) mice to delete the Smoothened receptor in the Shh pathway, we demonstrate that the loss of Shh signaling in Shh expressing cells results in a transient increase in proliferation and subsequent depletion of mDA neuron progenitors in the posterior vMes due to the facilitated cell cycle exit. Moreover, the change in duration of Shh signaling in vMes progenitors altered the timing of the contribution to the ventral tegmental area (VTA) and the substantia nigra pars compacta (SNc) mDA neurons. Taken together, our investigation on the relationship between the Shh-secreting and -responding cells revealed an intricate regulation of induction and cessation of Shh signaling that influences the distribution of mDA neurons in the VTA and SNc.

Characterization of partially purified 8 kDa antigenic protein of Clonorchis sinensis  

PubMed Central

The 8 kDa antigenic protein of Clonorchis sinensis was partially purified by ammonium sulfate precipitation and subsequently by a column chromatographic steps. The purified protein was separated into 7 and 8 kDa protein bands through SDS-tricine gel electrophoresis, while the protein was found to migrate to a 8 kDa band in 7.5-15% SDS-PAGE. The molecular weight of the antigen was estimated to be 110 kDa by Superose 6 HR 10/30 gel filtration. The purified antigen strongly reacted with the human sera of clonorchiasis. The hyperimmune sera of BALB/c mice immunized against the 8 kDa protein were reacted with both the crude extract and the excretory-secretory product of adult worms, but not with the metacercarial extract. Immunohistochemical staining demonstrated that the protein was distributed to the tegument and subtegumental cells and also to the seminal receptacle. The present findings suggest that the 8 kDa protein is a partition of the multicomplex protein originating from various organs of adult C. sinensis, and that it is composed of several 7 and 8 kDa proteins.

Therapeutic effect of infused Fluosol-DA/carbogen with ephedrine, flunarizine, or nitroprusside  

SciTech Connect

The perfluorochemical emulsion Fluosol-DA plus carbogen breathing has been shown to increase the effectiveness of radiation therapy in preclinical solid tumors when the emulsion was administered by i.v. bolus injection. Much of the enhancement in tumor radiation response was lost when the emulsion was administered slowly. The authors hypothesized that an increase in tumor perfusion resulted when Fluosol-DA was administered rapidly. In the present study, the [alpha]/[beta] agonist ephedrine, the Ca[sup 2+] channel blocker flunarizine and the nitric oxide producing vasodilating drug nitroprusside have been tested. Ephedrine administration resulted in a decrease in the radiation plus Fluosol-DA [+-] carbogen antitumor effects in both the Lewis lung carcinoma and FSaIIC tumor systems. In contrast, flunarizine administration resulted in an increase in the efficacy of the radiation plus carbogen and the radiation plus Fluosol-DA/carbogen in both emulsion was given rapidly. Even with flunarizine administration Fluosol-DA delivered slowly was less effective than when the emulsion was given rapidly. Flunarizine with Fluosol-DA infused i.v. over 30 min followed by carbogen breathing prior to and during radiation therapy resulted in a 1.7-1.6-fold increase in response compared with 2.4-2.2-fold with Fluosol-DA administered by injection i.v. and carbogen breathing prior to and during radiation therapy using growth delay of the Lewis lung carcinoma. The effects of nitroprusside were complex. This drug had considerably more effect at 10 Gy than at higher radiation doses. These studies suggest that Fluosol-DA given by i.v. injection may increase tumor perfusion and that a drug like flunarizine may be beneficial if the Fluosol-DA is administered slowly followed by carbogen breathing and radiation therapy. 45 refs., 4 figs.

Heterohexamer of 56- and 63-kDa Gene 4 Helicase-Primase of Bacteriophage T7 in DNA Replication*  

PubMed Central

Bacteriophage T7 expresses two forms of gene 4 protein (gp4). The 63-kDa full-length gp4 contains both the helicase and primase domains. T7 phage also express a 56-kDa truncated gp4 lacking the zinc binding domain of the primase; the protein has helicase activity but no DNA-dependent primase activity. Although T7 phage grow better when both forms are present, the role of the 56-kDa gp4 is unknown. The two molecular weight forms oligomerize by virtue of the helicase domain to form heterohexamers. The 56-kDa gp4 and any mixture of 56- and 63-kDa gp4 show higher helicase activity in DNA unwinding and strand-displacement DNA synthesis than that observed for the 63-kDa gp4. However, single-molecule measurements show that heterohexamers have helicase activity similar to the 63-kDa gp4 hexamers. In oligomerization assays the 56-kDa gp4 and any mixture of the 56- and 63-kDa gp4 oligomerize to form more hexamers than does the 63-kDa gp4. The zinc binding domain of the 63-kDa gp4 interferes with hexamer formation, an inhibition that is relieved by the insertion of the 56-kDa species. Compared with the 63-kDa gp4, heterohexamers synthesize a reduced amount of oligoribonucleotides, mediated predominately by the 63-kDa subunits via a cis mode. During coordinated DNA synthesis 7% of the tetraribonucleotides synthesized are used as primers by both heterohexamers and hexamers of the 63-kDa gp4. Overall, an equimolar mixture of the two forms of gp4 shows the highest rate of DNA synthesis during coordinated DNA synthesis.

Myelin management by the 18.5-kDa and 21.5-kDa classic myelin basic protein isoforms  

PubMed Central

The classic myelin basic protein (MBP) splice isoforms range in nominal molecular mass from 14 to 21.5 kDa, and arise from the gene in the oligodendrocyte lineage (Golli) in maturing oligodendrocytes. The 18.5-kDa isoform that predominates in adult myelin adheres the cytosolic surfaces of oligodendrocyte membranes together, and forms a two-dimensional molecular sieve restricting protein diffusion into compact myelin. However, this protein has additional roles including cytoskeletal assembly and membrane extension, binding to SH3-domains, participation in Fyn-mediated signaling pathways, sequestration of phosphoinositides, and maintenance of calcium homeostasis. Of the diverse post-translational modifications of this isoform, phosphorylation is the most dynamic, and modulates 18.5-kDa MBP’s protein-membrane and protein-protein interactions, indicative of a rich repertoire of functions. In developing and mature myelin, phosphorylation can result in microdomain or even nuclear targeting of the protein, supporting the conclusion that 18.5-kDa MBP has significant roles beyond membrane adhesion. The full-length, early-developmental 21.5-kDa splice isoform is predominantly karyophilic due to a non-traditional P-Y nuclear localization signal, with effects such as promotion of oligodendrocyte proliferation. We discuss in vitro and recent in vivo evidence for multifunctionality of these classic basic proteins of myelin, and argue for a systematic evaluation of the temporal and spatial distributions of these protein isoforms, and their modified variants, during oligodendrocyte differentiation.

2012 DA14 and Chelyabinsk: Same Day Coincidence?  

NASA Astrophysics Data System (ADS)

A long anticipated near-miss by near-Earth asteroid (NEA) 2012 DA14 on 15 February 2013 was upstaged 16 hours earlier by the impact and atmospheric explosion of a ~20 m NEA over Chelyabinsk, Russia. DA14 was earlier estimated to be 45 m across and passage at a distance under geosynchronous satellites was considered to be a record close approach by an object of that size, a once-in-40-years event. Actual Earth impact by a 20 m NEA had been estimated to be a once-in-200-years event. A simplistic calculation gives a probability of these happening on the same day of 1-in-a-billion. Within hours of the Chelyabinsk impact, it was recognized and widely reported that the two asteroids were in very different orbits and could not, at least in any readily understandable way, be physically related to each other (e.g. fragments of the same precursor body). Also, some early reports suggested that the two asteroids had very different compositions, further undermining the possibility they were pieces of the same body. (It seems unlikely, though certainly conceivable, that the two NEAs could have different compositions yet have some kind of causal connection resulting in the same-day events.) Nevertheless, incredibly tiny probabilities beg for an explanation. Here, with the benefit of hindsight, I re-examine issues that affect the probabilities, such as size, albedo, probable composition, and numbers of NEAs of these sizes. I also consider difficult issues of framing the apparent coincidence, which dominate other uncertainties. Updated information about the physical nature of the two asteroids somewhat modifies the original estimates of probabilities. Moreover, more proper ways of framing elements of the coincidence considerably reduce the improbability of the same-day events, but not nearly to the level (e.g. 1-in-1000 or perhaps 1-in-10,000) where we could rationalize dismissing the events as “just a coincidence.” The events of 15 February 2013 deserve more sophisticated investigation.

Leonardo Da Vinci and stroke - vegetarian diet as a possible cause.  

PubMed

Leonardo da Vinci (April 15, 1452 to May 2, 1519) was an Italian Renaissance architect, musician, anatomist, inventor, engineer, sculptor, geometer, and painter. It has been gleaned from the many available historical documents that da Vinci was a vegetarian who respected and loved animals, and that he suffered from right hemiparesis in the last 5 years of his life. A vegetarian diet has both positive and negative influences on the cerebrovascular system. In this report, a possible relation between a vegetarian diet and stroke is discussed from various perspectives as related to Leonardo da Vinci's stroke. PMID:20375518

GOoDA: The Generic Optimization Data Analyzer  

NASA Astrophysics Data System (ADS)

Modern superscalar, out-of-order microprocessors dominate large scale server computing. Monitoring their activity, during program execution, has become complicated due to the complexity of the microarchitectures and their IO interactions. Recent processors have thousands of performance monitoring events. These are required to actually provide coverage for all of the complex interactions and performance issues that can occur. Knowing which data to collect and how to interpret the results has become an unreasonable burden for code developers whose tasks are already hard enough. It becomes the task of the analysis tool developer to bridge this gap. To address this issue, a generic decomposition of how a microprocessor is using the consumed cycles allows code developers to quickly understand which of the myriad of microarchitectural complexities they are battling, without requiring a detailed knowledge of the microarchitecture. When this approach is intrinsically integrated into a performance data analysis tool, it enables software developers to take advantage of the microarchitectural methodology that has only been available to experts. The Generic Optimization Data Analyzer (GOoDA) project integrates this expertise into a profiling tool in order to lower the required expertise of the user and, being designed from the ground up with large-scale object-oriented applications in mind, it will be particularly useful for large HENP codebases

DA?NE Operation with Electron-Cloud-Clearing Electrodes  

NASA Astrophysics Data System (ADS)

The effects of an electron cloud (e-cloud) on beam dynamics are one of the major factors limiting performances of high intensity positron, proton, and ion storage rings. In the electron-positron collider DA?NE, namely, a horizontal beam instability due to the electron-cloud effect has been identified as one of the main limitations on the maximum stored positron beam current and as a source of beam quality deterioration. During the last machine shutdown in order to mitigate such instability, special electrodes have been inserted in all dipole and wiggler magnets of the positron ring. It has been the first installation all over the world of this type since long metallic electrodes have been installed in all arcs of the collider positron ring and are currently used during the machine operation in collision. This has allowed a number of unprecedented measurements (e-cloud instabilities growth rate, transverse beam size variation, tune shifts along the bunch train) where the e-cloud contribution is clearly evidenced by turning the electrodes on and off. In this Letter we briefly describe a novel design of the electrodes, while the main focus is on experimental measurements. Here we report all results that clearly indicate the effectiveness of the electrodes for e-cloud suppression.

Mitogen-induced tyrosine phosphorylation of 41 kDa and 43 kDa proteins. Potential role in integrating multiple mitogenic signalling pathways.  

PubMed Central

We have examined the possible involvement of pertussis toxin (PT)-sensitive GTP-binding protein and protein kinase C (PKC) in mitogen-induced tyrosine phosphorylation of the 41 kDa and 43 kDa cytosol proteins using PT-pretreated (inactivation of PT-sensitive GTP-binding protein) or phorbol 12-myristate 13-acetate (PMA)-pretreated (depletion of PKC) mouse fibroblasts. The effects of the inactivation of PT-sensitive GTP-binding protein and the depletion of PKC on mitogen-stimulated tyrosine phosphorylation of the proteins were similar and varied significantly and systematically in response to growth factors. The important finding was that such inhibitory effects of PT-sensitive GTP-binding protein inactivation and PKC depletion on protein tyrosine phosphorylation induced by each mitogen always correlated well with their inhibitory effects on each mitogen-stimulated DNA synthesis. Although the extent of platelet-derived-growth-factor-induced phosphorylation of the proteins was decreased to approx. 50% in PT- and PMA-pretreated cells compared with native cells, protein phosphorylation itself was not affected and occurred at identical sites on each protein in native, PT- and PMA-pretreated cells. These results suggest that: (1) 41 kDa and 43 kDa proteins are located downstream of PT-sensitive GTP-binding protein and PKC in the mitogenic signalling pathways of growth factors, (2) protein phosphorylation occurs via a cascade of events which includes the activation of the receptor tyrosine kinases, PKC and other unidentified kinase(s) which directly participate(s) in the phosphorylation of the 41 kDa and 43 kDa proteins, and (3) their phosphorylation may play an important role in integrating multiple mitogenic signalling pathways.

Immune response of electroeluted detergent soluble 29 kDa antigen from Setaria digitata (Von Linstow).  

PubMed

Filariasis is one of the typical parasitic infections which cause immune suppression during the course of infection in both humans and experimental animals. A 29 kDa protein isolated from detergent soluble antigen of S. digitata showed maximum inhibition of cell mediated immune response. The heat inactivated 29 kDa protein was found to be devoid of property of suppression of immune response in the host. Histological study of spleen of BALB/C mice immunized with 29 kDa protein showed changes in regions of spleen such as follicle, trabeculae, capsule, reticuloendothelial cells and eosinophils. The 29 kDa protein, the most reactive of the detergent soluble proteins produced partial suppression of immune response, thereby contributing to the factors responsible for the survival of filarial parasites in hosts.

Determinação de regiões de órbitas diretas estáveis ao redor da Lua  

NASA Astrophysics Data System (ADS)

Neste Trabalho estamos investigando regiões do sistema Terra-Lua que contêm órbitas diretas estáveis ao redor da Lua visando a utilização destas órbitas em futuras missões de veículos espaciais como alternativas de trajetórias com baixo custo de manutenção. Adotando-se o problema restrito de três corpos, Terra-Lua-partícula, a localização e a extensão destas regiões de estabilidade foram investigadas numericamente considerando como estável toda órbita que permanece ao redor a Lua por, no mínimo, 1000 dias com energia de dois corpos da partícula em relação à Lua negativa. A estabilidade de tais regiões está associada a duas famílias de órbitas periódicas simples H1 e H2 e a órbitas quase-periódicas associadas a elas. Uma vez identificadas as regiões de estabilidade passamos a analisá-las introduzindo, paulatinamente, outras interações relevantes ao sistema como as perturbações do Sol (via problema restrito de quatro corpos), das marés, da pressão de radiação e do achatamento terrestre. Os resultados encontrados até o momento mostram que a perturbação do Sol é a única que reduz significativamente o tamanho das regiões de estabilidade. Também estamos investigando o comportamento de tais regiões quando características intrínsecas do sistema como as excentricidades das órbitas da Terra e da Lua e a inclinação da órbita Lua são consideradas. Com este estudo estamos reunindo informações que nos permitirão compreender a evolução das regiões de estabilidade no sistema Terra-Lua, bem como estabelecer parâmetros adequados para a utilização das trajetórias estáveis em futuras missões espaciais.

In vitro degradation of the 32kDa PS II reaction centre protein  

SciTech Connect

The 32kDa thylakoid membrane protein is an integral component of the PS II reaction centre. The protein, although stable in the dark, undergoes light dependent turnover. Light from the UV, visible and far-red spectral regions induce 32kDa protein degradation. To better understand 32kDa protein metabolism, an in vitro degradation system is being developed. It consists of isolated thylakoid membranes than contain radiolabelled protein. The 32kDa protein is actively and specifically degraded when the thylakoid preparation is exposed to UV or visible radiation. The protein is stable in the dark. The herbicides (atrazine and DCMU) inhibit degradation in the in vitro system as they do in vivo. Additionally, several methods of isolating thylakoids are being compared to optimize the 32kDa protein degradation reaction. The preparations will be evaluated based on their ability to permit light dependent degradation of the 32kDa protein without affecting the other membrane components.

Data Assimilation techniques are essential elements in state-of-the-art development of models and their use in operational forecasting and real-time control in the fields of groundwater, surface water and soil systems. In meteorological and atmospheric sciences, steady improvements in numerical weather forecasting and climate prediction over the last couple of decades have been enabled to a large degree by the development of community-based models and data assimilation systems. The hydrologic community should learn from the experiences of the meteorological and atmospheric communities by accelerating the transition of hydrologic DA research into operations and developing community-supported, open-source modeling and forecasting systems and data assimilation tools. In 2010, a community based open source initiative named OpenDA was started. The openDA initiative bears similarities with the well-known openMI initiative. OpenDA makes use of a set of interfaces that describe the interaction between models, observations and data assimilation algorithms. It focuses on flexible applications in portable systems for modeling geophysical processes. It provides a generic interfacing protocol that allows combination of the implemented data assimilation techniques with, in principle, any time-stepping model describing a process (atmospheric processes, 3D circulation, 2D water flow, rainfall-runoff, unsaturated flow, groundwater flow, etc.). Presently, openDA features filtering techniques and calibration techniques. The presentation will give an overview of openDA and the results of some of its practical applications.

Nicotinamide, Fluosol DA and Carbogen: a strategy to reoxygenate acutely and chronically hypoxic cells in vivo.  

PubMed Central

The effect of Nicotinamide and/or treatment with Fluosol DA and Carbogen breathing on the radiation response of 500-750 mg SCCVII and KHT tumours has been evaluated. Pretreatment with Fluosol DA/Carbogen or Nicotinamide resulted in relatively modest enhancements of radiation damage with enhancement factors of 1.1 and 1.3 being observed using an in vivo/in vitro clonogenic end-point. A combination of Nicotinamide and Fluosol DA/Carbogen resulted in a larger enhancement factor of 1.6 over the radiation dose ranges studied. These modification factors reflect a value close to that expected for a fully aerobic response in this survival range. Growth delay studies in the SCCVII tumour provided similar results. Using a recently developed fluorescence activated cell sorting technique, which utilizes the in vivo pharmacokinetic and DNA binding properties of the bisbenzamide stain Hoechst 33342, the effect of Nicotinamide and/or Fluosol DA/Carbogen schedules on the occurrence of acute hypoxia was assessed. The results clearly show that Nicotinamide significantly reduces the amount of 'acute hypoxia', but has a lesser effect on 'chronic' hypoxic cells. However, combinations of Nicotinamide and Fluosol DA/Carbogen significantly increase the response of both 'acutely' and 'chronically hypoxic' cells. The results provide evidence that a combination of Nicotinamide and Fluosol DA/Carbogen can provide an effective way of reoxygenating both acutely and chronically hypoxic cells.

An antibody against 100- to 116-kDa polypeptides in coated vesicles inhibits triskelion binding  

SciTech Connect

There is considerable evidence that the 100- to 116-kDa polypeptides in calf brain coated vesicles are involved in the assembly of clathrin triskelions to form coated vesicles. The authors have raised polyclonal antibodies against these polypeptides. By Western blot analysis, these antibodies bind to a distinct subset of the six polypeptides in the region 100-116 kDa. Whole cell homogenates from calf brain, calf liver, and rat liver also show immunoreactivity in the 100-kDa region with no other cross reactivity. Isolated coated vesicles from calf liver, rat brain, and soybean roots also cross-react. Stripped coated vesicles, which are depleted of clathrin but which retain the 100- to 116-kDa polypeptides, quantitatively rebind {sup 125}I-triskelions. These studies indicate that (1) specific sites on the 100- to 116-kDa polypeptides are required for assembly of coated vesicles, and (2) this antibody will be useful in clarifying more precisely the role of the 100- to 116-kDa polypeptides in coated vesicle recycling.

The 32kDa enamelin undergoes conformational transitions upon calcium binding.  

PubMed

The 32 kDa hydrophilic and acidic enamelin, the most stable cleavage fragment of the enamel specific glycoprotein, is believed to play vital roles in controlling crystal nucleation or growth during enamel biomineralization. Circular dichroism and Fourier transform infrared spectra demonstrate that the secondary structure of the 32 kDa enamelin has a high content of alpha-helix (81.5%). Quantitative analysis on the circular dichroism data revealed that the 32 kDa enamelin undergoes conformational changes with a structural preference to beta-sheet with increasing concentration of calcium ions. We suggest that the increase of beta-sheet conformation in the presence of Ca(2+) may allow preferable interaction of the 32 kDa enamelin with apatite crystal surfaces during enamel biomineralization. The calcium association constant (K(a)=1.55 (+/-0.13)x10(3)M(-1)) of the 32 kDa enamelin calculated from the fitting curve of ellipticity at 222 nm indicated a relatively low affinity. Our current biophysical studies on the 32 kDa enamelin structure provide novel insights towards understanding the enamelin-mineral interaction and subsequently the functions of enamelin during enamel formation.

DaPKC-dependent phosphorylation of Crumbs is required for epithelial cell polarity in Drosophila.  

PubMed

Both in Drosophila and vertebrate epithelial cells, the establishment of apicobasal polarity requires the apically localized, membrane-associated Par-3-Par-6-aPKC protein complex. In Drosophila, this complex colocalizes with the Crumbs-Stardust (Sdt)-Pals1-associated TJ protein (Patj) complex. Genetic and molecular analyses suggest a functional relationship between them. We show, by overexpression of a kinase-dead Drosophila atypical PKC (DaPKC), the requirement for the kinase activity of DaPKC to maintain the position of apical determinants and to restrict the localization of basolateral ones. We demonstrate a novel physical interaction between the apical complexes, via direct binding of DaPKC to both Crb and Patj, and identify Crumbs as a phosphorylation target of DaPKC. This phosphorylation of Crumbs is functionally significant. Thus, a nonphosphorylatable Crumbs protein behaves in vivo as a dominant negative. Moreover, the phenotypic effect of overexpressing wild-type Crumbs is suppressed by reducing DaPKC activity. These results provide a mechanistic framework for the functional interaction between the Par-3-Par-6-aPKC and Crumbs-Sdt-Patj complexes based in the posttranslational modification of Crb by DaPKC.

The 32 kDa Enamelin Undergoes Conformational Transitions upon Calcium Binding  

PubMed Central

The 32 kDa hydrophilic and acidic enamelin, the most stable cleavage fragment of the enamel specific glycoprotein, is believed to play vital roles in controlling crystal nucleation or growth during enamel biomineralization. Circular dichroism and Fourier transform infrared spectra demonstrate that the secondary structure of the 32 kDa enamelin has a high content of ?-helix (81.5%). Quantitative analysis on the circular dichroism data revealed that the 32 kDa enamelin undergoes conformational changes with a structural preference to ?-sheet as a function of calcium ions. We suggest that the increase of ?-sheet conformation upon presence of Ca2+ may allow preferable interaction of the 32 kDa enamelin with apatite crystal surfaces during enamel biomineralization. The calcium association constant of the 32 kDa enamelin calculated from the fitting curve of ellipticity at 222 nm is Ka = 1.55 (±0.13) × 103 M?1, indicating a relatively low affinity. Our current biophysical studies on the 32 kDa enamelin structure provide novel insights towards understanding the enamelin-mineral interaction and subsequently the functions of enamelin during enamel formation.

D-amphetamine (A)-induced dopamine (DA) release is not strictly dependent on newly-synthesized transmitter  

SciTech Connect

A is thought to exert its stimulant effects by releasing DA from a newly synthesized transmitter pool. This hypothesis was evaluated directly by measuring the basal efflux and electrically-evoked release of endogenous DA and dihydroxyphenylacetic acid (DOPAC). In striatal slices from reserpine-treated rabbits A increased DA efflux, reduced DOPAC efflux, and inhibited electrically-evoked /sup 3/H-ACh release in a concentration-dependent manner. These effects could not be mimicked by inhibition of neuronal uptake or MAO, but were blocked by inhibition of DA synthesis or neuronal uptake, and were potentiated by inhibition of MAO. In slices with intact vesicular transmitter stores A induced DA efflux was 2-fold greater than that seen in slices having no vesicular stores. Inhibition of DA synthesis reduced A-induced DA efflux by 60%, but had little effect on the ability of A to inhibit /sup 3/H-ACh release. A also increased the electrical stimulation-evoked overflow of DA (an effect which was attenuated slightly by synthesis inhibition), and potently inhibited DOPAC overflow. These results suggest that: 1) A facilitates efflux of axoplasmic DA by an accelerated exchange diffusion mechanism. The releasable axoplasmic pool is derived from newly synthesized and vesicular transmitter pools; 2) postsynaptic indices of transmitter release may be misleading; and 3) A increases electrically-evoked DA release possibly by inhibiting neuronal uptake.

Vinpocetine and ?-tocopherol prevent the increase in DA and oxidative stress induced by 3-NPA in striatum isolated nerve endings.  

PubMed

Vinpocetine is a neuroprotective drug that exerts beneficial effects on neurological symptoms and cerebrovascular disease. 3-nitropropionic acid (3-NPA) is a toxin that irreversibly inhibits succinate dehydrogenase, the mitochondrial enzyme that acts in the electron transport chain at complex II. In previous studies in striatum-isolated nerve endings (synaptosomes), we found that vinpocetine decreased dopamine (DA) at expense of its main metabolite 3,4-dihydroxyphenylacetic acid (DOPAC), and that 3-NPA increased DA, reactive oxygen species (ROS), DA-quinone products formation, and decreased DOPAC. Therefore, in this study, the possible effect of vinpocetine on 3-NPA-induced increase in DA, ROS, lipid peroxidation, and DA-quinone products formation in striatum synaptosomes were investigated, and compared with the effects of the antioxidant ?-tocopherol. Results show that the increase in DA induced by 3-NPA was inhibited by both 25 ?M vinpocetine and 50 ?M ?-tocopherol. Vinpocetine, as ?-tocopherol, also inhibited 3-NPA-induced increase in ROS (as judged by DCF fluorescence), lipid peroxidation (as judged by TBA-RS formation), and DA-quinone products formation (as judged by the nitroblue tetrazolium reduction method). As in addition to the inhibition of complex II exerted by 3-NPA, 3-NPA increases DA-oxidation products that in turn can inhibit other sites of the respiratory chain, the drop in DA produced by vinpocetine and ?-tocopherol may importantly contribute to their protective action from oxidative damage, particularly in DA-rich structures.

Therapeutic Potential of Dioscorea Extract (DA-9801) in Comparison with Alpha Lipoic Acid on the Peripheral Nerves in Experimental Diabetes.  

PubMed

DA-9801, a mixture of extracts from Dioscorea japonica Thunb. and Dioscorea nipponica Makino, was reported to have neurotrophic activity. Therefore, we investigated the therapeutic potential of DA-9801, in comparison with alpha lipoic acid (ALA), for peripheral nerves preservation in experimental diabetes. Experimental animals were divided into 4 groups, and each group was designated according to the type of treatment administered as follows: normal, DM, DM+DA-9801, and DM+ALA. After 16 weeks, response thresholds to tactile and thermal stimuli were higher in DM+DA-9801 group than in nontreated DM group. This degree of increase in DM+DA-9801 group indicates more therapeutic potency of DA-9801 than ALA. Western blot analysis showed more significant increase in NGF and decrease in TNF-? and IL-6 in DM+DA-9801 group than in DM or DM+ALA groups (P < 0.05). IENF density was reduced less significantly in the DM+DA-9801 group than in other DM groups (7.61?±?0.32, 4.2?±?0.26, and 6.5?±?0.30 in DM+DA-9801, DM, and DM+ALA, resp., P < 0.05). Mean myelinated axonal area in the sciatic nerves was significantly greater in DM+DA-9801 group than in other DM groups (69.2?±?5.76, 54.0?±?6.32, and 63.1?±?5.41 in DM+DA-9801, DM, and DM+ALA, resp., P < 0.05). Results of this study demonstrated potential therapeutic applications of DA-9801 for the treatment of diabetic peripheral neuropathy. PMID:23671883

Audio watermarking robust against D/A and A/D conversions  

NASA Astrophysics Data System (ADS)

Digital audio watermarking robust against digital-to-analog (D/A) and analog-to-digital (A/D) conversions is an important issue. In a number of watermark application scenarios, D/A and A/D conversions are involved. In this article, we first investigate the degradation due to DA/AD conversions via sound cards, which can be decomposed into volume change, additional noise, and time-scale modification (TSM). Then, we propose a solution for DA/AD conversions by considering the effect of the volume change, additional noise and TSM. For the volume change, we introduce relation-based watermarking method by modifying groups of the energy relation of three adjacent DWT coefficient sections. For the additional noise, we pick up the lowest-frequency coefficients for watermarking. For the TSM, the synchronization technique (with synchronization codes and an interpolation processing operation) is exploited. Simulation tests show the proposed audio watermarking algorithm provides a satisfactory performance to DA/AD conversions and those common audio processing manipulations.

Low strain, long life creep fatigue of AF2-1DA and INCO 718  

SciTech Connect

Two aircraft turbine disk alloys, GATORIZED AF2-DA and INCO 718 were evaluated for their low strain long life creep-fatigue behavior. Static (tensile and creep rupture) and cyclic properties of both alloys were characterized. The cntrolled strain LCF tests were conducted at 760 C (1400 F) and 649 C (1200 F) for AF2-1DA and INCO 718, respectively. Hold times were varied for tensile, compressive and tensile/compressive strain dwell (relaxation) tests. Stress (creep) hold behavior of AF2-1DA was also evaluated. Generally, INCO 718 exhibited more pronounced reduction in cyclic life due to hold than AF2-1DA. The percent reduction in life for both alloys for strain dwell tests was greater at low strain ranges (longer life regime). Changing hold time from 0 to 0.5, 2.0 and 15.0 min. resulted in corresponding reductions in life. The continuous cycle and cyclic/dwell initiation failure mechanism was predominantly transgranular for AF2-1DA and intergranular for INCO 718.

In vitro study on the interaction between the 32 kDa enamelin and amelogenin.  

PubMed

Enamel extracelluar matrix components play vital roles in controlling crystal nucleation and growth during enamel formation. We investigated the interaction between the 32 kDa enamelin fragment and amelogenin using immunochemical and biophysical methods. Immunoprecipitation studies revealed that the 32 kDa enamelin and amelogenin eluted together from a Protein A column. Dynamic light scattering results showed that the 32 kDa enamelin had a profound effect on amelogenin assembly at pH 8.0, causing partial dissociation of the nanospheres, in a dose-dependent manner. The appearance of an isodichroic point and the shifting and intensity decrease of the ellipticity minima in the circular dichroism spectra of amelogenin following the addition of the 32 kDa enamelin were indicative of conformational changes in amelogenin and of a direct interaction between the two macromolecules. Our results collectively demonstrate that the 32 kDa enamelin has a direct interaction with amelogenin in vitro. Our current studies provide novel insights into understanding possible cooperation between enamelin and amelogenin in macromolecular self-assembly and in controlling enamel mineral formation.

Intramolecular proteolytic nicking and binding of Bacillus thuringiensis Cry8Da toxin in BBMVs of Japanese beetle.  

PubMed

Bacillus thuringiensis (Bt) Cry8D insecticidal proteins are unique among Cry8 family proteins in terms of its insecticidal activity against adult Scarab beetles, such as Japanese beetle (Popillia japonica Newman). From the sequence homology with other Bt Cry proteins especially those active against beetles, such as Cry3Aa whose 3D structure is available, the structure of the Cry8D protein has been predicted to be a typical three-domain Cry protein type. In addition, the activation process of Cry8D in gut juice of susceptible insects is presumed to be similar to that of Cry3A (Yamaguchi et al., 2008). In this study, the activation process of Cry8Da in insect gut juice was closely examined. Japanese beetle gut juice proteases digested the 130kDa Cry8Da protein to produce a 64kDa protein. This 64kDa protein was active against both adult and larval Japanese beetle and considered to be an activated toxin. N-terminal sequencing of this 64kDa protein revealed that the Cry8Da leader sequence consisting of 63 amino acid residues from M(1) to F(63) was removed. As in the case of Cry3Aa, the proteases further digested the 64kDa protein to two 8kDa and 54kDa fragments. N-terminal amino acid analysis of these smaller fragments indicated that the proteases digested the loop between Alpha Helix (Alpha for short) 3 and Alpha 4. This means that the 8kDa fragment consists of Alpha 1-3 of Domain I and that the 54kDa fragment contains the remaining Domain I and full Domain II and Domain III. Size exclusion chromatography and anion exchange chromatography could not separate these 64, 54 and 8kDa proteins suggesting that the 54kDa and 8kDa fragments are still forming the toxin complex equivalent to the 64kDa protein by size and ionic charge. The sequencing and chromatography results suggest that the gut juice proteases merely nicked the loop between Alpha 3 and Alpha 4. This nicking process appeared to be essential for receptor binding of the Cry8Da toxin. BBMV binding assay revealed that the Cry8Da toxin bound to BBMV preparations from both adult and larval Japanese beetle only after the loop was nicked. Only the 54kDa fragment bound to the BBMV preparations but not the 64kDa protein. Ligand blot showed that the protease activated Cry8Da toxin, presumably the 54kDa fragment, bound to specific BBMV proteins, one or more of those would be receptor(s). The sizes and binding affinities of these Cry8Da-bound proteins of Japanese beetle BBMV differed between larvae and adults. PMID:20655921

Chronic 5-HT Transporter Blockade Reduces DA Signaling to Elicit Basal Ganglia Dysfunction  

PubMed Central

Serotonin (5-HT)-selective reuptake inhibitors (SSRIs) are widely administered for the treatment of depression, anxiety, and other neuropsychiatric disorders, but response rates are low, and side effects often lead to discontinuation. Side effect profiles suggest that SSRIs inhibit dopaminergic activity, but mechanistic insight remains scarce. Here we show that in mice, chronic 5-HT transporter (5-HTT) blockade during adulthood but not during development impairs basal ganglia-dependent behaviors in a dose-dependent and reversible fashion. Furthermore, chronic 5-HTT blockade reduces striatal dopamine (DA) content and metabolism. A causal relationship between reduced DA signaling and impaired basal ganglia-dependent behavior is indicated by the reversal of behavioral deficits through l-DOPA administration. Our data suggest that augmentation of DA signaling would reduce side effects and increase efficacies of SSRI-based therapy.

Goldstone Radar Images of Near-Earth Asteroid 2012 DA14  

NASA Astrophysics Data System (ADS)

2012 DA14 made an extremely close approach within 0.00023 AU (0.09 lunar distances) on February 15, 2013. This was the closest encounter known in advance by a near-Earth asteroid with an absolute magnitude brighter than 25. We took advantage of this opportunity to image 2012 DA14 at Goldstone on February 16, 18, and 19 as the asteroid was receding from Earth. The imaging started at 00:46 UTC, slightly more than five hours after the closest approach, when the asteroid was at a distance of 0.00088 AU (0.34 lunar distances). The echoes were extraordinarily strong and we obtained some of the highest signal-to-noise ratios for any near-Earth asteroid ever observed at Goldstone. The images achieved resolutions as fine as 3.75 m x 0.00625 Hz that spatially resolve 2012 DA14 into a few dozen pixels; however, due to the diminutive dimensions of the asteroid, even this extremely high resolution is insufficient to show detailed surface features. The images indicate that 2012 DA14 is an asymmetric, angular, and elongated object with major axes of roughly 40 x 20 meters. The sequence of images obtained on February 16 spans 7.8 hours, during which the orientation of the asteroid appeared to complete close to one full rotation, suggesting that the rotation period is somewhat longer than ~8 hours. Radar speckle tracking with the Very Large Array and elements of the Very Long Baseline array show that 2012 DA14 has a relatively low obliquity and constrain the amplitude of any non-principal axis wobble after the flyby to be < 30 degrees. 2012 DA14 is among the smallest near-Earth asteroids ever spatially resolved by radar and it highlights the substantial scientific potential of the new chirp imaging system at Goldstone.

Abundâncias de oxigênio e enxofre nas estrelas de tipo solar da vizinhança solar  

NASA Astrophysics Data System (ADS)

Alguns resultados sugerem que o Sol seja 58% mais abundante em oxigênio que o meio interestelar local. Esta anomalia parece estender-se para o carbono e o criptônio. Entre as possíveis explicações deste fenômeno estão: uma supernova de tipo II que tenha enriquecido a nebulosa protosolar, tornando-a superabundante em oxigênio; um episódio de infall de material pobre em metais sobre o disco Galático, diluindo o meio interestelar local ou uma migração dinâmica do Sol de uma órbita mais interna da Galáxia para sua posição atual. A escolha entre estes cenários exige o conhecimento preciso da abundância solar em relação às anãs G da vizinhança. Neste contexto, o oxigênio e enxofre, são elementos-chave por serem ambos produzidos pelas supernovas de tipo II, devendo portanto possuir o mesmo padrão de abundância. Este projeto visa esclarecer qual a posição do Sol na distribuição local de abundâncias de enxofre e oxigênio para uma amostra de estrelas de tipo solar com idades e metalicidades bem conhecidas. Para tal, analisamos espectros de alta resolução e alta relação sinal-ruído nas regiões espectrais de ll 6300, 7774 (O) e l8695 (S). Para o enxofre encontramos que o Sol parece ser uma estrela típica dentre as da vizinhança, e que este elemento não mostra a sobreabundância para baixas metalicidades, já bem estabelecida para o oxigênio. Discutimos as abundâncias do enxofre no contexto da Evolução Química da Galáxia. Apresentamos resultados preliminares muito precisos para a linha proibida do oxigênio l6300 e comparamos estes com os obtidos para o tripleto em l7774. Quantificamos os efeitos não-ETL presentes no tripleto em função dos parâmetros atmosféricos estelares.

Two monoclonal antibodies (OKT27 and OKT27b) have been produced that react with distinct epitopes of a 95-kDa peptide. The T27 antigen is widely distributed, being expressed on B lymphocytes, monocytes, and adult T-leukemic cells but not on polymorphonuclear leukocytes or platelets. There was a low level of T27 expression on resting T cells that increased on T-cell activation. In preliminary

Diagnostic role of the antibody response to the 38kDa, 16kDa proteins and lipoarabinomannan of mycobacterium tuberculosis.  

PubMed

The antibody response to the 38kDa, 16kDa and Lipoarabinomannan (LAM) antigens ofMycobacterium tuberculosis was evaluated using three different ELISAs based on these antigens. The study group included tuberculosis patients (n=52), patients with HIV and TB co-infection (n=10), other chest symptomatics (n=5), HIV infected individuals (n=10), leprosy cases (n=7) and healthy controls (n=75). The results indicate that the 38kDa and LAM based ELISA for IgM/IgG has a low specificity (ranging from 69-85%) and sensitivity (ranging from 55-78%). When three ELISAs are carried out on a single patient the probability of detection of tuberculosis was significantly increased to 95.2% indicating that a single ELISA test is of low sensitivity and that a combination of ELISA's may be needed to be of any value as a diagnostic test for tuberculosis. Additionally, a western blot assay of the serum antibody response to protein fraction ofM. tuberculosis was analysed in 15 tuberculosis patients and five healthy controls. A multiple antibody response to various M.tuberculosis proteins was observed which varied from patient to patient as compared to controls who showed a single 38-39 kDa protein band positivity. These finding suggest that a western blot assay which determines the antibody response to a set of antigenic components ofM. tuberculosis could be a better serological test for the diagnosis of tuberculosis in our population.

The First Korean Experience of Telemanipulative Robot-Assisted Laparoscopic Cholecystectomy Using the da Vinci System  

PubMed Central

With the advancement of laparoscopic instruments and computer sciences, complex surgical procedures are expected to be safely performed by robot assisted telemanipulative laparoscopic surgery. The da Vinci system (Intuitive Surgical, Mountain View, CA, USA) became available at the many surgical fields. The wrist like movements of the instrument's tip, as well as 3-dimensional vision, could be expected to facilitate more complex laparoscopic procedure. Here, we present the first Korean experience of da Vinci robotic assisted laparoscopic cholecystectomy and discuss the introduction and perspectives of this robotic system.

Solubilization of insoluble inorganic phosphate by Burkholderia cepacia DA23 isolated from cultivated soil  

PubMed Central

A mineral phosphate solubilizing bacterium, Burkholderia cepacia DA23 has been isolated from cultivated soils. Phosphate-solubilizing activities of the strain against three types of insoluble phosphate were quantitatively determined. When 3% of glucose concentration was used for carbon source, the strain had a marked mineral phosphate-solubilizing activity. Mineral phosphate solubilization was directly related to the pH drop by the strain. Analysis of the culture medium by high pressure liquid chromatography identified gluconic acid as the main organic acid released by Burkholderia cepacia DA23. Gluconic acid production was apparently the result of the glucose dehydrogenase activity and glucose dehydrogenase was affected by phosphate regulation.

Two-weekly dose-adjusted (DA)-EPOCH-like chemotherapy with high-dose dexamethasone plus rituximab (DA-EDOCH14-R) in poor-prognostic untreated diffuse large B-cell lymphoma.  

PubMed

The activity and safety of two-weekly dose-adjusted (DA)-EPOCH (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin)-like chemotherapy with high-dose dexamethasone plus rituximab (DA-EDOCH14-R) was explored in 20 patients with previously untreated poor prognosis diffuse large B-cell lymphoma (DLBCL). The main outcomes were compared with those of 27 poor-prognosis patients enrolled into a previous trial of 3-weekly DA-EPOCH-R. Toxicity was manageable and there were no therapy-related deaths. Three-year progression-free survival (PFS) was superior in the DA-EDOCH14-R group (95% vs. 74%, P = 0·08). Importantly, this improvement in PFS with the two-weekly DA-EDOCH14-R was particularly notable in patients with an age-adjusted International Prognostic Index of 3 (100% vs. 30%, P < 0·001).

Identification of a Bacillus thuringiensis Cry8Da toxin-binding glucosidase from the adult Japanese beetle, Popillia japonica.  

PubMed

Cry8Da from Bacillus thuringiensis galleriae SDS-502 has insecticidal activity against both the larvae and adult Japanese beetle (Popillia japonica Newman). The receptor determines the specificity of the insecticidal activity of Cry proteins and hence, in order to reveal the mode of action of Cry toxin, receptor identification is a necessary step. However, a receptor for Cry8-type toxin has not been identified in the Scarabaeidae family of insects. Therefore, we aimed to identify the receptor of Cry8Da toxin in adult P. japonica BBMV. A ligand blot showed the Cry8Da toxin only bound to a 150kDa protein in the BBMV of adult P. japonica. In order to identify the Cry8Da toxin binding protein, it was purified by column chromatography and three internal amino acid sequences were determined. Two of the three internal amino acid sequences shared homology with Coleopteran ?-glucosidases. In addition, the fraction containing the Cry8Da toxin binding protein had ?-glucosidase activity but no aminopeptidase N and alkaline phosphatase activity, both of which are commonly reported as receptors for Cry toxins in Lepidopteran and Dipteran insects. The ?-glucosidase homologous genes could be amplified by PCR using degenerate oligonucleotide primers designed from a conserved sequence of Coleopteran ?-glucosidases and an internal amino acid sequence of the Cry8Da toxin binding protein. Taken together, the ?-glucosidase in adult P. japonica BBMV is the receptor for B. thuringiensis Cry8Da toxin. PMID:23541518

Validation of the Delvotest SP NT DA. Performance Tested Method 011101.  

PubMed

Delvotest SP NT DA is designed to test milk for the presence of antibacterial substances, such as antibiotics. The test is made of an agar gel containing bacterial spores and a color indicator. The milk sample is added onto the agar gel, and the test is incubated at 64 degrees C. The principle of the test is based on the diffusion of possible inhibitory substances that may be present in the milk sample into agar. This reduces growth and acid production by the test organism, and delays or prevents the agar from changing color from purple to yellow. The Delvotest Accelerator is an automated system in which the plates containing the milk to be analyzed are placed for incubation. The Accelerator automatically detects the end of the incubation and reads the results. A sample containing antibiotic will be noted as "positive." A sample without antibiotics or with antibiotics at concentrations below detection level will be noted as "negative." The present report includes all technical details about the Delvotest SP NT DA, and the results of the validation study. The validation study demonstrates that the Delvotest SP NT DA conforms to the product performance claims and confirms the robustness of the test. The Delvotest SP NT DA is, therefore, granted Performance Tested Method certification. PMID:22468368

Este trabalho apresenta o roteiro piloto de uma prática observacional em astronomia, junto com os primeiros resultados obtidos nesta fase de implementacão. O projeto, que será executado em duas etapas, visa introduzir noções de Astronomia a alunos do Ensino Médio e iniciantes nos cursos de Física. O experimento consiste em medir as órbitas dos satélites Galileanos e, a partir da análise dos dados coletados, verificar a validade da Lei das órbitas de Kepler, determinando a massa do planeta Júpiter. Em uma primeira etapa, as observações serão feitas utilizando um telescópio Meade LX200 10" e câmera CCD para obter uma seqüência de imagens do planeta, que possibilitará medir o movimento de seus satélites. A segunda etapa terá início a partir do funcionamento do telescópio em modo robótico, com a possibilidade de observações via internet por instituições de ensino. Para o desenvolvimento deste experimento foram inicialmente coletadas várias imagens de Júpiter obtidas com os instrumentos citados acima. Estas imagens serviram como base para confecção dos roteiros para a experiência no nível médio e superior. Os roteiros serão inicialmente apresentados em uma home-page. Nela também se buscará uma contextualização histórica da experiência bem como o estabelecimento de relações com professores e alunos, propostas metodológicas e a disponibilização dos programas computacionais necessários para a utilização "on-line" pelos usuários. O projeto conta com apoio da Fundação VITAE.

Microsomes, isolated from 18-day-old chicken embryos were treated with phospholipase A2 to solubilize the NTE activity. The extract was then combined with polyoxyethylene W1 detergent and resolved by gel filtration chromatography to yield an active fraction with an approximate mass of 200 kDa. This fraction was further purified by preparative isoelectric focusing and native electrophoresis to yield two separate bands possessing NTE activity. The slower migrating band was highly enriched in a 155-kDa protein that was identified as a source of the NTE activity by affinity chromatography using 3-(9'-mercaptononylthio)-1,1,1-trifluoro-propan-2-one bound to Sepharose CL6B. This represents the first report of the isolation of NTE in its active form and aids in the confirmation of the 155-kDa protein as the most likely candidate for NTE. PMID:8812209

Monoclonal antibodies against 24?kDa surface antigen of hepatitis B viruses.  

PubMed

Hepatitis B virus (HBV) infection is one of the major public health problems worldwide. Effective control of HBV transmission in areas of high and intermediate endemicity would not be possible without vaccination of the vulnerable group. The diagnosis of acute and chronic hepatitis B infection is based on the detection of hepatitis B surface antigen (HBsAg). In this study, we prepared nine hybridomas that produced monoclonal antibodies specific for HBsAg. BALB/c mice were immunized with 24?kDa HBsAg and the immune spleen cells were fused with SP2/0 myeloma cell line. We obtained seven IgG1, one IgM, and one IgG2b positive clones. The stable hybrids were sub-cloned and ascitic fluid was prepared in the BALB/c mice. After antibody purification by protein G, the affinity column was prepared and the pure 24?kDa HBsAg from cell extract was eluted from the column. Western blot analysis showed that all monoclonal antibodies are specific for 24?kDa antigen. Since 24?kDa HBsAg is used for vaccination against hepatitis, these monoclonal antibodies are the best candidate for the isolation and purification of recombinant HBsAg from yeast expression vector by affinity column to be used for vaccination.

Translocation of an 89-kDa periplasmic protein is associated with Holospora infection  

SciTech Connect

The symbiotic bacterium Holospora obtusa infects the macronucleus of the ciliate Paramecium caudatum. After ingestion by its host, an infectious form of Holospora with an electron-translucent tip passes through the host digestive vacuole and penetrates the macronuclear envelope with this tip. To investigate the underlying molecular mechanism of this process, we raised a monoclonal antibody against the tip-specific 89-kDa protein, sequenced this partially, and identified the corresponding complete gene. The deduced protein sequence carries two actin-binding motifs. Indirect immunofluorescence microscopy shows that during escape from the host digestive vacuole, the 89-kDa proteins translocates from the inside to the outside of the tip. When the bacterium invades the macronucleus, the 89-kDa protein is left behind at the entry point of the nuclear envelope. Transmission electron microscopy shows the formation of fine fibrous structures that co-localize with the antibody-labeled regions of the bacterium. Our findings suggest that the 89-kDa protein plays a role in Holospora's escape from the host digestive vacuole, the migration through the host cytoplasm, and the invasion into the macronucleus.

Uniform remote control of front end processors in PAN-DA  

SciTech Connect

The PAN-DA data acquisition software system encompasses support for a variety of front end processors including the Struck General Purpose Master (GPM), the Fermilab Smart Crate Controller (FSCC), and the Motorola MVME133-A VME single board computer. PAN-DA provides support for the remote control of these processors through its Remote Procedure eXecution (RPX) software. This software runs over serial lines, and in some PAN-DA environments, over the Ethernet and TCP/IP as well. Experiments E791 and E771 have successfully used RPX software in both FSCC software development and data collection during the 1990--1991 fixed target run at Fermilab. RPX software has facilitated development and testing of the Fermilab Silicon Strip Detector readout system, for which the FSCC is an integral component. RPX based control and monitoring of the GPM and the MVME133-A are essential parts of the PAN-DA data acquisition system used by E687 and E773 during the 1990--1991 run. 6 refs., 2 figs.

A 23-kDa protein as a substrate for protein kinase C in bovine neutrophils. Purification and partial characterization  

SciTech Connect

In {sup 32}P{sub i}-loaded bovine neutrophils stimulated with phorbol myristate acetate (PMA), radioactivity was preferentially incorporated into a protein of low molecular mass, suggesting a PKC-dependent phosphorylation. This protein, termed 23-kDa protein, was predominantly localized in the cytosol. The apparent molecular mass of the purified protein range between 20 and 23 kDa. In the absence of mercaptoethanol, a dimer accumulated. Homogeneity of the 23-kDa protein was verified by 2D-PAGE analysis. Gel isoelectric focusing (IEF) of the purified 23-kDa protein followed by Coomassie blue staining allowed the visualization of our discrete protein bands with isoelectric points ranging between pH 6.3 and 6.7. Phosphorylation of the 23-kDa protein by ({gamma}-{sup 32}P)ATP in the presence of bovine neutrophil PKC supplemented with Ca{sup 2+}, phosphatidylserine, and diacylglycerol or with PMA occurred on serine and required the presence of mercaptoethanol. IEF of the {sup 32}P-labeled 23-kDa protein followed by autoradiography revealed for discrete bands with distinct isoelectric points similar to those of the bands stained by Coomassie blue after IEF on nonlabeled 23-kDa protein. The bands of the 23-kDa protein resolved by IEF and transfered to nitrocellulose showed ability to bind ({sup 35}S)GTP-{gamma}-S. The immunoreactivity of antibodies raised in rabbits against the bovine neutrophil 23-kDa protein was demonstrated on immunoblots after SDS-PAGE. The 23-kDa protein differed also from several other proteins of similar molecular mass that have been identified in neutrophils, namely, calmodulin, the small subunit of the low-potential cytochrome b, and a low molecular weight protein which is ADP-ribosylated by the botulinum toxin.

Isoform composition and stoichiometry of the approx. 90-kDa heat shock protein associated with glucocorticoid receptors  

SciTech Connect

The authors observed that the approx. 90-kDa non-steroid-binding component of nonactivated glucocorticoid receptors purified from WEHI-7 mouse thymoma cells (which has been identified as the approx. 90-kDa heat shock protein) consistently migrates as a doublet during polyacrylamide gel electrophoresis under denaturing and reducing conditions. It has recently been reported that murine Meth A cells contain a tumor-specific transplantation antigen (TSTA) which is related or identical to the approx. 90-kDa heat shock protein. The observation that TSTA and the approx. 90-kDa heat shock protein isolated from these cells exists as two isoforms of similar molecular mass and charge has suggested that the doublet observed is also due to the existence of two isoforms. They have therefore conducted this study to determine whether TSTA and the approx. 90-kDa component of glucocorticoid receptors are indeed related, to establish whether the receptor preferentially binds one isoform of the approx. 90-kDa heat shock protein, and to investigate the stoichiometry of the nonactivated receptor complex. They used the BuGr1 and AC88 monoclonal antibodies to purify, respectively, receptor-associated and free approx. 90-kDa heat shock protein from WEHI-7 cells grown for 48 h with (/sup 35/S)methionine to metabolically label proteins to steady state. The long-term metabolic labeling approach has also enabled them to directly determine that the purified non-activated glucocorticoid receptor contains a single steroid-binding protein and two approx. 90-kDa non-steroid-binding subunits. The consistency with which a approx. 1:2 stoichiometric ratio of steroid binding to approx. 90-kDa protein is observed supports the view that the approx. 90-kDa heat shock protein is a true component of nonactivated glucocorticoid-receptor complexes.

Effects of acute amphetamine (AMPH) treatment on rat striatal dopamine (DA) receptor activity  

SciTech Connect

Upon administration of AMPH rats display a complex series of dose and time dependent behaviors and changes in dopaminergic activity. They found a decrease in D1 DA receptor-stimulated adenylate cyclase (DA-AC) activity in rat striatal membranes after acute in vivo AMPH at a dose and time of intense stereotyped behavior. The Ka for D1-AC activity increased and the Vmax decreased in striatal membranes from rats given 7.5 mg/kg AMPH i.p. and killed 1 hr later as compared to saline (SAL) controls. They examined whether the decrease of DA-AC was due to a change in receptor number or activation of GTP-binding protein, Ns. Female Holtzman rats were injected with SAL or 7.5 mg/kg AMPH and killed 1 hr later. A 27,000 x g striatal particulate fraction was prepared for AC assay or (/sup 3/H)DA binding with 10 nM spiroperidol. They found no difference in stimulation of AC by NaF, GTP or GppNHp at any dose tested in membranes from SAL- and AMPH-treated rats. Calmodulin-stimulated AC was also unchanged after AMPH. Specific binding at a saturating concentration of (/sup 3/H)DA was 191 +/- 31 and 117 +/- 14 fmol/mg prot in membranes from SAL- and AMPH-treated rats, respectively. This suggests an alteration is occurring at the level of the D1 receptor rather than at coupling of Ns with the AC catalytic subunit.

PanDA Pilot Submission using Condor-G: Experience and Improvements  

SciTech Connect

PanDA (Production and Distributed Analysis) is the workload management system of the ATLAS experiment, used to run managed production and user analysis jobs on the grid. As a late-binding, pilot-based system, the maintenance of a smooth and steady stream of pilot jobs to all grid sites is critical for PanDA operation. The ATLAS Computing Facility (ACF) at BNL, as the ATLAS Tier1 center in the US, operates the pilot submission systems for the US. This is done using the PanDA 'AutoPilot' scheduler component which submits pilot jobs via Condor-G, a grid job scheduling system developed at the University of Wisconsin-Madison. In this paper, we discuss the operation and performance of the Condor-G pilot submission at BNL, with emphasis on the challenges and issues encountered in the real grid production environment. With the close collaboration of Condor and PanDA teams, the scalability and stability of the overall system has been greatly improved over the last year. We review improvements made to Condor-G resulting from this collaboration, including isolation of site-based issues by running a separate Gridmanager for each remote site, introduction of the 'Nonessential' job attribute to allow Condor to optimize its behavior for the specific character of pilot jobs, better understanding and handling of the Gridmonitor process, as well as better scheduling in the PanDA pilot scheduler component. We will also cover the monitoring of the health of the system.

Aliphatic lipid substitution on 2 kDa polyethylenimine improves plasmid delivery and transgene expression.  

PubMed

This study was conducted in order to develop amphiphilic, low molecular weight polymeric carriers for nonviral gene delivery. Caprylic, myristic, palmitic, stearic, oleic and linoleic acids were grafted onto the 2 kDa polyethylenimine (PEI) and properties critical for gene delivery were investigated using 293T and bone marrow stromal cells. The extent of lipid substitution on the polymers was controlled by the lipid:PEI feed ratio during the synthesis. The toxicity of the native and lipid-substituted 2 kDa PEI was relatively lower than the 25 kDa PEI, although lipid substitution generally increased the toxicity of the polymers in vitro. Lipid substitution reduced the ability of the polymers to complex DNA, as well as the stability of final complexes, as measured by heparin-induced dissociation. Once fully complexed to a plasmid DNA, however, the lipid-substituted polymers increased the plasmid DNA delivery to the cells. In 293T cells, the lipid-substituted polymers displayed a transfection ability that was equivalent to highly effective 25 kDa PEI, but without the toxic effect associated with the latter polymer. Among the lipids explored, no particular lipid emerged as the ideal substituent for transgene expression, although linoleic acid appeared to be superior to other lipid substituents. No correlation was evident between the level of substitution and DNA delivery efficiency of the polymers, and as little as 1 lipid substitution per PEI was effective in transforming the ineffective 2 kDa PEI into an effective carrier. The current structure-function studies are providing important clues about the properties critical for gene delivery and providing carriers effective for nonviral plasmid delivery. PMID:19719326

Characterization of a bioactive 15 kDa fragment produced by proteolytic cleavage of chicken growth hormone.  

PubMed

There is evidence for a cleaved form of GH in the chicken pituitary gland. A 25 kDa band of immunoreactive-(ir-)GH, as well as the 22 kDa monomeric form and some oligomeric forms were observed when purified GH or fresh pituitary extract were subjected to SDS-PAGE under nonreducing conditions. Under reducing conditions, the 25 kDa ir-GH was no longer observed, being replaced by a 15 kDa band, consistent with reduction of the disulfide bridges of the cleaved form. The type of protease involved was investigated using exogenous proteases and monomeric cGH. Cleaved forms of chicken GH were generated by thrombin or collagenase. The site of cleavage was found in position Arg133-Gly134 as revealed by sequencing the fragments produced. The NH2-terminal sequence of 40 amino acid residues in the 15 kDa form was identical to that of the rcGH and analysis of the remaining 7 kDa fragment showed an exact identity with positions 134-140 of cGH structure. The thrombin cleaved GH and the 15 kDa form showed reduced activity (0.8% and 0.5% of GH, respectively) in a radioreceptor assay employing a chicken liver membrane preparation. However, this fragment had a clear bioactivity in an angiogenic bioassay and was capable to inhibit the activity of deiodinase type III in the chicken liver. PMID:11720252

Whole-genome sequences of DA and F344 rats with different susceptibilities to arthritis, autoimmunity, inflammation and cancer.  

PubMed

DA (D-blood group of Palm and Agouti, also known as Dark Agouti) and F344 (Fischer) are two inbred rat strains with differences in several phenotypes, including susceptibility to autoimmune disease models and inflammatory responses. While these strains have been extensively studied, little information is available about the DA and F344 genomes, as only the Brown Norway (BN) and spontaneously hypertensive rat strains have been sequenced to date. Here we report the sequencing of the DA and F344 genomes using next-generation Illumina paired-end read technology and the first de novo assembly of a rat genome. DA and F344 were sequenced with an average depth of 32-fold, covered 98.9% of the BN reference genome, and included 97.97% of known rat ESTs. New sequences could be assigned to 59 million positions with previously unknown data in the BN reference genome. Differences between DA, F344, and BN included 19 million positions in novel scaffolds, 4.09 million single nucleotide polymorphisms (SNPs) (including 1.37 million new SNPs), 458,224 short insertions and deletions, and 58,174 structural variants. Genetic differences between DA, F344, and BN, including high-impact SNPs and short insertions and deletions affecting >2500 genes, are likely to account for most of the phenotypic variation between these strains. The new DA and F344 genome sequencing data should facilitate gene discovery efforts in rat models of human disease. PMID:23695301

On the incidence of weak magnetic fields in DA white dwarfs  

NASA Astrophysics Data System (ADS)

Context. About 10% of white dwarfs have magnetic fields with strength in the range between about 105 and 5 × 108 G. It is not known whether the remaining white dwarfs are not magnetic, or if they have magnetic fields too weak to be detected with the techniques adopted in the large surveys. Information is particularly lacking for the cooler (and generally fainter) white dwarfs. Aims: We describe the results of the first survey specifically devised to clarify the detection frequency of kG-level magnetic fields in cool DA white dwarfs. Methods: Using the FORS1 instrument of the ESO VLT, we have obtained Balmer line circular spectropolarimetric measurements of a small sample of cool (DA6 - DA8) white dwarfs. Using FORS and UVES archive data, we have also revised numerous white dwarf field measurements previously published in the literature. Results: We have discovered an apparently constant longitudinal magnetic field of ~9.5 kG in the DA6 white dwarf WD 2105-820. This star is the first weak-field white dwarf that has been observed sufficiently to roughly determine the characteristics of its field. The available data are consistent with a simple dipolar morphology with magnetic axis nearly parallel to the rotation axis, and a polar strength of ? 56 kG. Our re-evaluation of the FORS archive data for white dwarfs indicates that longitudinal magnetic fields weaker than 10 kG have previously been correctly identified in at least three white dwarfs. However, for one of these three weak-field stars (WD 2359-434), UVES archive data show a ~100 kG mean field modulus. Either at the time of the FORS observations the star's magnetic field axis was nearly perpendicular to the line of sight, or the star's magnetic field has rather complex structure. Conclusions: We find that the probability of detecting a field of kG strength in a DA white dwarf is of the order of 10% for each of the cool and hot DA stars. If there is a lower cutoff to field strength in white dwarfs, or a field below which all white dwarfs are magnetic, the current precision of measurements is not yet sufficient to reveal it. Based on observations collected at the European Organisation for Astronomical Research in the Southern Hemisphere, Chile, under observing programme 073.D-0516, and obtained from the ESO/ST-ECF Science Archive Facility.Table 3 is available in electronic form at http://www.aanda.org

The interaction of Cresol Red derivatives (Cresol Red (o-Cresolsulfonphthalein), Cresol Red-DA (3,3'-Bis [N,N-di (carboxymethyl) aminomethyl]-o-cresolsulfonphthalein) and Cresol Red-DA-Fe(III) (3,3'-Bis [N,N-di (carboxymethyl) aminomethyl]-o-cresolsulfonphthalein-Ferrous(III)) with bovine serum albumin (BSA) were studied by the combination of ultraviolet spectroscopy, circular dichroism (CD) spectroscopy, fluorescence spectroscopy and synchronous fluorescence spectroscopy. On that basis, the sonodynamic and sonocatalytic damages of Cresol Red derivatives to BSA under ultrasonic irradiation were also investigated by means of corresponding spectrum technology. Meanwhile, some influenced factors such as ultrasonic irradiation time, Cresol Red derivatives concentration and ionic strength on the damage degree of BSA molecules were also reviewed. In addition, the binding site and damage site of BSA molecules were estimated by synchronous fluorescence spectra. Finally, the results of oxidation-extraction photometry (OEP) using several reactive oxygen species (ROS) scavengers indicated that the damage of BSA molecules is mainly due to the generation of ROS. Perhaps, this paper may offer some important subjects for broadening the application of Cresol Red derivatives in sonodynamic therapy (SDT) and sonocatalytic therapy (SCT) technologies for tumor treatment.

Design and technology in the development of potters' lathes for modeling with terracota: the case of Cabo de Santo Agostinho.  

PubMed

This article reports the experience of the design team of the Laboratory The Imaginary in the process of developing an electric potter's lathe which respects the biomechanics of the body, helps to development the task, maintains the archetype of traditional equipment, and improves the mechanical efficiency of the power transmission system. The design method used was based on the axes of research, analysis, development and monitoring, and focused on the product and with partners: the artisans and engineering and production teams. The main results point to ergonomic improvements in the biomechanical and dimensional aspects, and a decrease in the risk of accidents and occupational diseases. The experience of this case also highlights the gains arising from the relationship between design, engineering and users (artisans) in developing products with a design that can be easily replicated for other communities of potters in the state. This and other actions are part of the outlook of the Laboratory the Imaginary which in partnership with local authorities, wishes to see the craft activities continue and to give value to the culture of the city.

Human risky choice in a repeated-gambles procedure: an up-linkage replication of Lakshminarayanan, Chen and Santos (2011).  

PubMed

Lakshminarayanan et al. (J Exp Soc Psychol 47: 689-693, 2011) showed that when choice is between variable (risky) and fixed (safe) food amounts with the same expected values, capuchins prefer the safe alternative if choice is framed as a gain, but the risky alternative if it is framed as a loss. These results seem similar to those seen in human prospect-theory tests in choice between variable and fixed gains or losses. Based on this similarity, they interpreted their results as identifying a between-species commonality in cognitive function. In this report, we repeat their experiment with humans as subjects (an up-linkage replication). Whether choices were rewarded with candy or nickels, choice approximated indifference whether framed as gains or losses. Our data mirror those of others who found that when humans make risky choices within a repeated-trials procedure without verbal instruction about outcome likelihoods, preference biases seen in one-shot, language-guided, prospect-theory tests such as Tversky and Kahneman's (Science 211:453-458, 1981) reflection effect may not appear. The disparity between our findings and those of Lakshminarayanan et al. suggests their study does not evidence a cognitive process shared by humans and capuchins. PMID:23526161

Cloning of 87 kDa outer membrane protein gene of Pasteurella multocida P52.

Pasteurella multocida serotype B:2 is the causative agent of haemorrhagic septicaemia, a fatal disease of cattle and buffaloes. Formalin inactivated whole cell bacterin is used to prepare vaccines in India. However, outer membrane proteins (OMPS) of P. multocida were reported to be potential immunogens. The 87-kDa OMP of P. multocida P52, serotype B:2 has been identified as one of the major antigens because this protein reacted with serum of vaccinated animals. The gene omp87, encoding an 87-kDa OMP was amplified and cloned into pBluescript SK(-) vector. This gene was found to localise in a 9.0 kb Hind III fragment of P. multocida genome. PMID:11676623

A photospheric metal line profile analysis of hot DA white dwarfs with circumstellar material  

NASA Astrophysics Data System (ADS)

Some hot DA white dwarfs have circumstellar high ion absorption features in their spectra, in addition to those originating in the photosphere. In many cases, the line profiles of these absorbing components are unresolved. Given the importance of the atmospheric composition of white dwarfs to studies of stellar evolution, extra-solar planetary systems and the interstellar medium, we examine the effect of including circumstellar line profiles in the abundance estimates of photospheric metals in six DA stars. The photospheric C and Si abundances are reduced in five cases where the circumstellar contamination is strong, though the relative weakness of the circumstellar Si iv absorption introduces minimal contamination, resulting in a small change in abundance. The inability of previous, approximate models to reproduce the photospheric line profiles here demonstrates the need for a technique that accounts for the physical line profiles of both the circumstellar and photospheric lines when modelling these blended absorption features.

Robot-assisted laparoendoscopic single-site pyeloplasty: technique using the da Vinci Si robotic platform.  

PubMed

Conventional laparoscopic dismembered pyeloplasty (LP) is an established alternative to open pyeloplasty given equivalent intermediate-term outcomes and decreased morbidity. Laparoendoscopic single-site (LESS) pyeloplasty has the potential to further decrease the morbidity of LP, while yielding superior cosmesis. It is, however, technically very challenging even with the use of an accessory port, largely because of the difficulty of intracorporeal suturing through a single umbilical incision. Application of the da Vinci robotic surgical platform to LESS pyeloplasty (R-LESS) has the potential to overcome these limitations. We describe our technique for R-LESS pyeloplasty using the da Vinci Si robot. We have found that use of the robotic system in conjunction with certain technique modifications helps to reduce the technical difficulty of LESS pyeloplasty and to shorten the physical learning curve associated with the procedure.

Crosslinking of hemin to a specific site on the 90-kDa ferritin repressor protein  

SciTech Connect

Incubation of a 90-kDa ferritin repressor protein (FRP) with small amounts of radiolabeled hemin resulted in the formation of a strong interaction between the two that was stable to SDS/PAGE. Of seven other proteins tested individually, only apohemopexin and bovine serum albumin showed similar crosslinking ability, albeit to a much lower extent. ({sup 14}C)Hemin specifically crosslinked to FRP in the presence of a 50-fold excess of total wheat germ proteins. Inclusion of catalase did not prevent the reaction of hemin with FRP, suggesting that H{sub 2}O{sub 2} is not involved. The subsequent addition of a stoichiometric amount of apohemopexin did not reverse the reaction. Exhaustive digestion of the complex with Staphylococcus aureus V8 protease produced a major labeled peptide of 17 kDa. These results show the existence of a highly specific, uniquely reactive hemin binding site on FRP.

A 232 MHz survey of the area centred on DA240  

NASA Astrophysics Data System (ADS)

A radio survey of the area (10° × 10°) centred on the giant radio galaxy DA240 (? = 07h45m, ? = 50.00') has been carried out with the Miyun aperture synthesis telescope at 232 MHz. The Miyun aperture synthesis telescope came into operation in October 1984. It consists of 28 paraboloids (all 9m in diameter) distributed on an EW baseline of 1.164 km, the resolution is 3'.8 × 3'.8 csc ? at 232 MHz. It has been shown (Tsien, 1982) that the thermal electron densities within the extended lobes and the eastern hotspot are very low (much less than 2 × 10 -5 cm -3). This suggests that DA240 may be located in a large-scale hole with very low mass density. Therefore, the investigation of the area centred on DA240 would be helpful to the study of the evolution of radio galaxies and to cosmology. The observational data obtained in November, 1984 have been reduced recently. A package has been developed especially for data analysis and image processing, including elimination of interferences, corrections of zero-point offset and phase distortions caused by the ionosphere and clean algorithm etc. The ionospheric effects caused by large-scale gradients have been the main problem. A self-calibration technique of "one-dimensional brightness distribution correlation" has been devised successfully for the instantaneous correction of ionospheric refraction. A good quality map of the whole area has been obtained, and more than one hundred sources with flux density greater than 0.22 Jy (the limiting flux density on the map) have been listed. The 232 MHz structure of DA240 cleaned with a Gaussian beam is shown in Fig. 3 and the central part of the map is shown in Fig. 4.
