Evaluation of geopressured brine injectability: Department of Energy, Pleasant Bayou No. 2 well, Brazoria County, Texas  

SciTech Connect

A field evaluation of geopressured brine injectability was completed during September 22 to 25, 1980 at the DOE, Brazoria test site in Texas. Membrane filters, with pore sizes of 0.4-..mu..m and 10.0-..mu..m, were used as the basis for obtaining suspended solids data and for developing performance-life estimates of typical spent brine injection wells. Field measurements were made at 130/sup 0/C and line pressures up to 3800 psig. Scale inhibited (phosphonate-polyacrylate threshold-type, carbonate scale inhibitor), prefiltered-scale-inhibited, and untreated brine were evaluated. Test results indicated that raw brine was highly injectable, while scale-inhibited brine had extremely low quality. The poor injectability of scale-inhibited brine resulted from partial precipitation of the scale inhibitor.

Groundwater withdrawals 1976, 1990, and 2000--10 and land-surface-elevation changes 2000--10 in Harris, Galveston, Fort Bend, Montgomery, and Brazoria Counties, Texas  

USGS Publications Warehouse

The study area comprising Harris County and parts of Galveston, Fort Bend, Montgomery, and Brazoria Counties in southeastern Texas forms part of one of the largest areas of land-surface-elevation change in the United States. Land-surface-elevation change in the study area primarily is caused by the withdrawal of groundwater. Groundwater withdrawn from the Chicot and Evangeline aquifers has been the primary source of water for municipal supply, industrial and commercial use, and irrigation in the study area. Groundwater withdrawals cause compaction of clay and silt layers abundant in the aquifers, which has in turn resulted in the widespread, substantial land-surface-elevation changes in the region with increased flooding. To estimate land-surface-elevation changes, the U.S. Geological Survey (USGS), in cooperation with the Harris-Galveston Subsidence District (HGSD), documented land-surface-elevation changes in the study area that occurred during 200010 and 200510 based on elevation data measured by 11 USGS borehole-extensometer sites, a National Geodetic Survey Continuously Operating Reference Station, and Global Positioning System Port-A-Measure (PAM) sites operated by the HGSD and the Fort Bend Subsidence District. Groundwater withdrawals in the study area also were documented for 1976, 1990, and 200010. In 1976, about 428.9 million gallons per day (Mgal/d) were withdrawn from the aquifer system in Harris County, but by 2000, because of HGSD regulation, withdrawals had decreased to about 337.8 Mgal/d, or about a 21-percent reduction since 1976. By 2010, withdrawals had decreased to about 227.1 Mgal/d, or about a 47-percent reduction since 1976. Among the counties in the study area, the largest decrease in groundwater withdrawals has occurred in Galveston County since 1976. In 1976, about 27.4 Mgal/d were withdrawn from the aquifer system, and by 2000, withdrawals had decreased to about 4.12 Mgal/d, or about an 85-percent reduction since 1976. By 2010, withdrawals had decreased to about 0.626 Mgal/d, or about a 98-percent decrease since 1976. Since the mid-1970s, Fort Bend and Montgomery Counties have undergone extensive urban development and corresponding large increases in groundwater withdrawals. Total groundwater withdrawal for Fort Bend County in 1976 was about 16.0 Mgal/d, and by 2000, withdrawals had increased to about 86.5 Mgal/d, or about a 441-percent increase since 1976. By 2010, withdrawals in Fort Bend County had increased to about 99.8 Mgal/d, or about a 524-percent increase since 1976. Total groundwater withdrawal for Montgomery County in 1976 was about 7.84 Mgal/d, and by 2000, withdrawals had increased to about 43.6 Mgal/d, or about a 456-percent increase since 1976. By 2010, withdrawals in Montgomery County had increased to about 64.2 Mgal/d, or about a 719-percent increase since 1976. Total groundwater withdrawal in Brazoria County in 1976 was about 18.0 Mgal/d, and by 2000, withdrawals had increased to about 26.0 Mgal/d, or about a 44-percent increase. By 2010, withdrawals in Brazoria County had increased to about 24.7 Mgal/d, or about a 37-percent increase since 1976. Measured land-surface-elevation changes from December 31, 2000, to December 31, 2010, ranged from an elevation increase of 0.06 feet (ft), or an average increase in elevation of 0.006 ft per year, at the Seabrook borehole extensometer located near Seabrook, Tex., to an elevation decrease of 1.28 ft, or an average decrease in elevation of 0.128 ft per year, at a PAM station north of Jersey Village, Tex. (PAM 07). Measured land-surface-elevation changes from December 31, 2005, to December 31, 2010, ranged from an elevation increase of 0.07 ft, or an average increase in elevation of 0.014 ft per year, at PAM 09 in far northeastern Harris County to an elevation decrease of 0.51 ft, or an average decrease in elevation of 0.102 ft per year, at PAM 07.

Upper Strawn (Desmoinesian) carbonate and clastic depositional environments, SE King County, TX  

SciTech Connect

The Pennsylvanian upper Strawn Group of southeast King County, Texas, provides a unique setting to study interactions between coeval carbonate and clastic deposition during the Desmoinesian. One of the most perplexing problems is the relationship of massive Pennsylvanian platform carbonates to shallow-water marine and deltaic sediments. Within the study area carbonate facies were deposited along the northern edge of the Knox-Baylor trough on the Spur platform, and terrigenous clastics were carried toward the Midland basin through the Knox-Baylor trough. Based on the analysis of subsurface cores, five carbonate lithofacies and four clastic lithofacies were recognized in southeast King County, Texas. The distribution and geometry of these lithofacies are related to variations in the rate of subsidence in the Knox-Baylor trough, Pennsylvanian tectonics, deltaic progradation, avulsion and compaction. The platform carbonates within the northern region record environments within the carbonate platform complex, including middle platform, outer platform, algal mound, and platform margin. The quartzarenitic sandstones within the southern region occur in a variety of complex depositional geometries, including distributary bar fingers, lobate deltas, and offshore bars. The upper Strawn Group provides an attractive area for exploration geology. Both carbonates and clastics provide excellent reservoirs from a depth of approximately 5,000 to 6,000 ft. Total production since the early 1940s, within the area is over 100,000,000 bbl of oil. Multiple pay zones within a 600-ft interval also provide an added incentive for exploration. Areas within and around the Knox-Baylor trough deserve additional study due to these relatively shallow, unexplored, multiple pay zones.

Public health assessment for Longhorn Army Ammunition Plant, Karnack, Harrison County, Texas, Region 6, CERCLIS number TX6213820529. Final report  

SciTech Connect

Longhorn Army Ammunition Plant (Longhorn) is an 8,493 acre government-owned former industrial facility approximately 14 miles northeast of Marshall, Harrison County, Texas. Longhorn has been intermittently in operation since 1942 when it was established to produce the explosive 2,4,6-trinitrotoluene (TNT). Pyrotechnic ammunition also was produced at Longhorn and Morton Thiokol Corporation produced a plastic explosive at the facility until August 1997. According to document record for the hazardous ranking system, releases of 1,3-dinitrobenzene, 1,3,5-trinitrobenzene, arsenic, barium, chromium, and lead occurred. The Agency for Toxic Substances and Disease Registry (ATSDR) reviewed available environmental information for the site and evaluated several potential exposure situations. These exposure situations include potential contact with site contaminants in surface water, sediment, surface soil, wasteline material, and groundwater. Although site-related contaminants have been found in these various environmental media, currently the contaminants are not accessible, on or off the site, at levels that would pose a public health threat. Based on available information, the authors have concluded that overall, the Longhorne Army Ammunition Plant poses on apparent public health hazard. In the future, the conclusion category for this site could change if additional data were to indicate that contaminants from the site were migrating towards the public water supply wells near the site.

Shallow groundwater monitoring at the SACROC oilfield, Scurry County, TX: good news for geologic storage of CO2 despite a complex hydrogeologic and geochemical setting (Invited)  

NASA Astrophysics Data System (ADS)

The SACROC water study is the first comprehensive research project with application to geologic storage (GS) of CO2 that focuses on collection and interpretation of field measurements of groundwater (water level and water chemistry data). CO2 has been injected for enhanced oil recovery at the SACROC oilfield in Scurry County, TX since 1972. Hence, we have a perfect natural laboratory and an analog for monitoring future commercial CO2 sequestration sites. Kinder Morgan currently operates the SACROC oilfield where over 150 million metric tons (MMT) of CO2 has been injected for EOR at ~2 km depth; over 75 MMT of the CO2 has been produced and re-injected. CO2 is assumed to be trapped in the deep subsurface at SACROC. The goals of monitoring shallow groundwater over CO2 injection sites are to (1) confirm that CO2 has remained in the deep subsurface and (2) assess impacts to water quality if CO2 were to migrate upward along conduit flow paths (e.g. leaking well bores). We collected groundwater and stratigraphic data within an ~3,000 km2 area centered on SACROC to establish regional variability prior to assessing potential impacts to groundwater from CO2 injection. Groundwater data include results from five sampling trips between June 2006 and November 2008, and a compilation of historical data from the Texas Water Development Board database, dating back to 1936. Sources of complexity that contribute to data interpretation challenges include: (1) regional historic oilfield activity, (2) multiple freshwater-bearing strata in the regional Dockum aquifer, (3) sampled wells screened in shallowest (30 m), deepest (150 m), or across both water-bearing zones, (4) variable discharge rate of sampled wells (<5 to >250 gpm), (5) groundwater flow divide that bisects SACROC, (6) variable aquifer recharge mechanisms, (7) temporal variability in groundwater levels and chemistry, (8) cation exchange, (9) presence of biogenically-produced CO2 in aquifer, and (10) incongruent dissolution of carbonate minerals (2% dolomite) in the clastic Dockum aquifer. Concentrations of most analytes in the Dockum aquifer overlying SACROC are not statistically different from regional water quality. Concentrations of chloride and bromide indicate impacts to Dockum aquifer water quality in areas of SACROC. This is probably a result of outdated (pre-1970s and therefore pre-CO2 injection) oilfield practices, and accidental release of co-produced brine. Complexity of the hydrogeology, aqueous geochemistry, and even the monitoring approach taken at SACROC has prompted numerous additional questions. However, the overall conclusion remains: There are no systematic impacts to shallow freshwater resources overlying, or in the vicinity of SACROC oilfield, resulting from CO2 injection. So for SACROC, we have answered objective (2) above, but are still working on (1). Data interpretation and modeling to aid design of effective monitoring of future CO2 GS sites using the vast amount of data from SACROC continues. This work has been supported by the United States Department of Energy National Energy Technology Laboratorys Southwest Regional Carbon Sequestration Partnership and Kinder Morgan.

First order leveling: Pleasant Bayou geothermal test site, Brazoria County, Texas  

SciTech Connect

First order leveling to be conducted as part of an environmental monitoring program for a geopressured test well was reported. 39.43 kilometers of first order levels were run to NGS specifications. Twelve Class B type bench marks were set to NGS specifications. The adjusted elevation of bench mark C-1209 was used as a starting elevation and is based on a supplementary adjustment of April 6, 1979 by NGS. The closure for the loop around the well site is -0.65 millimeters. The distance around the loop is 1.29 kilometers, the allowable error of closure was 4.54 millimeters. The initial leveling of this well was performed in 1977. A thorough search for their monumentation was conducted. No monuments were found due to the lack of adequate monument descriptions. Therefore, an elevation comparison summary for this report is only available along the NGS lines outside the well area. The first order level tie to line No. 101 (BMA-1208) was +3.37 millimeters in 17.21 kilometers. The allowable error of closure was 12.44 millimeters.

New BVRI light curves from this study and radial velocity curves from Popper (1970) were solved simultaneously using modern light and radial velocity curves synthesis methods. The general results show that TX Her is a well-detached eclipsing binary, however, both component stars fill at least half of their Roche lobes. A significant third light contribution to the total light of the system could not be determined. Using O- C residuals formed by the updated minima times, an orbital period study of the system was performed. It was confirmed that the tilted sinusoidal O- C variation corresponds to an apparent period variation caused by the light travel time effect due to an unseen third body. The following absolute parameters of the components were derived: M1 = 1.62 0.04 M ?, M2 = 1.45 0.03 M ?, R1 = 1.69 0.03 R ?, R2 = 1.43 0.03 R ?, L1 = 8.21 0.90 L ? and L2 = 3.64 0.60 L ?. The distance to TX Her was calculated as 155 10 pc, taking into account interstellar extinction. The position of the components of TX Her in the HR diagram are also discussed. The components are young stars with an age of 500 Myr.

Final report for the geothermal well site restoration and plug and abandonment of wells: DOE Pleasant Bayou test site, Brazoria County, Texas  

SciTech Connect

For a variety of reasons, thousands of oil and gas wells have been abandoned in the Gulf Coast Region of the United States. Many of these wells penetrated geopressured zones whose resource potential for power generation was undervalued or ignored. The U.S. Department of Energy (DOE) Geopressured-Geothermal Research Program was chartered to improve geothermal technology to the point where electricity could be commercially produced from a substantial number of geopressured resource sites. This research program focused on relatively narrow technical issues that are unique to geopressured resources such as the ability to predict reservoir production capacity based on preliminary flow tests. Three well sites were selected for the research program. These are the Willis Hulin and Gladys McCall sites in Louisiana, and the Pleasant Bayou site in Texas. The final phase of this research project consists of plug and abandonment (P&A) of the wells and site restoration.

Hydrocephalus in the H-Tx rat: a monogenic disease?  

PubMed

The H-Tx rat is a genetic model of hydrocephalus for which thereis a poor understanding of the mode of inheritance. Previous studies suggested a polygenicmode of inheritance but the breeding data to supportthis hypothesis have not been reported. In an attempt to clarify the hereditary mode we have analyzed the data from eight generations of H-Tx rats and four generations of cross-matings between H-Tx rats and Sprague-Dawley (SD) rats. In the H-Tx rat colony 113 of 129 random brother-sister matings (87.60%) produced hydrocephalic offspring, with males and females being equally affected. The overall incidence varied greatly with an average of 30. 35%. In matings with more than three litters, all mating pairs yielded hydrocephalic pups. In cross-matings both hydrocephalic and normal H-Tx rats were mated with normal SD rats. No hydrocephalus was observed in the first generation of 124 pups (F1). Subsequent brother-sister matings of F1 animals generated hydrocephalic pups in the F2 generation with a lower incidence (4.67% in hydrocephalic HTx/SD matings and 5.11% in normal HTx/SD matings, respectively) than in the H-Tx rat colony (30.35%). Back-cross-matings between F2 rats and normal H-Tx rats yielded an incidence of hydrocephalus higher than that of the cross-matings but lower than that of the H-Tx colony. These data strongly suggest that the H-Tx rat is a homozygous carrier of an autosomal recessive hydrocephalus gene with incomplete penetrance. Furthermore, the data clearly rule out sex-linked and polygenic modes of inheritance and provide further insight with respect to genetic inheritance of hydrocephalus. PMID:10785451

TX Cancri - Which component is hotter  

NASA Technical Reports Server (NTRS)

The question is considered of whether the W-type light curves of TX Cnc result from a slightly higher temperature for the low-mass component or from a relatively strong classical gravity-darkening law. Photometric parameters for this W UMa binary area derived using light curves from four epochs exhibiting dissimilar behavior. The analysis is performed for up to five colors, and solutions are obtained by two different approaches in which the temperature difference between the components is treated as a free parameter or is determined by the surface gravitational field. The results of the second approach show that the polar effective temperature of the low-mass star is about 30 K cooler than that of the high-mass star, while the results of the first approach show the low-mass star to be 125 to 175 K hotter. Preference is given to the second approach because gravity darkening provides a simple and adequate explanation of the light curves. Epoch-to-epoch changes in the gravity-darkening and albedo parameters are taken as suggesting differences in the degree of thermal contact over a time scale of a few years.

Tx polyagglutination in three members of one family.  

PubMed

A case of acute haemolytic anaemia is described in a child. Tx polyagglutination of his red cells was observed, but no direct association with the anaemia could be proved. Polyagglutination was suspected because of irregularities in the AB0 blood grouping. Confirmation of the cryptantigen Tx was made when the patient's red cells were tested with lectins including Arachis hypogaea, Glycine soja, and Vicia cretica. Examination of family members showed Tx polyagglutination on the red cells of 2 siblings. The Tx polyagglutination was a transient phenomenon lasting 4-5.5 months, and could have been caused as the result of some unidentified bacterial or viral infection. Guidelines for transfusion therapy are suggested in patients in whom polyagglutination is recognised. PMID:3116808

Optical and infrared photometry of TX Canum Venaticorum  

SciTech Connect

UBVRJHK photometry during 1979--1982 indicates significant variability in the TX CVn binary system, with the optical brightness diminishing and the object growing redder. In the U band the amplitude was roughly-equal0/sup m/.6, while in the near infrared the brightness declined by 0/sup m/.1, on the average. To within +- 1 subtype, in 1981 the radiation of the system comprised that of a normal K5 giant and a B9 main-sequence star. The rest of the time excess optical emission was present, probably coming from a hot spot. The K-band flux density of the K5 giant implies a distance for TX CVn of roughly-equal1.1 kpc.

Mass flow in the interacting binary TX Ursae Majoris  

NASA Technical Reports Server (NTRS)

Twenty-two far-ultraviolet and 23 near-ultraviolet high resolution IUE spectra of the interactive Algol-type binary TX Ursae Majoris (B8 V + F-K III-IV) were analyzed in order to determine the nature of the mass flow occurring in this system. Absorption features due to high-temperature ions of Si IV, C IV, and N V are always present. The resonance lines of Al III, Fe II, Mg II and Si IV show strong phase and secular variations indicative of gas streaming and circumstellar/circumbinary material. Radial velocities as high as 500 to 600 km/sec are present. The gas flow is particularly prominent in 1985 between phases 0.7 and 0.0. The system is more active than U Sagittae and as active as U Cephei.

CX-100 and TX-100 blade field tests.  

SciTech Connect

In support of the DOE Low Wind Speed Turbine (LWST) program two of the three Micon 65/13M wind turbines at the USDA Agricultural Research Service (ARS) center in Bushland, Texas will be used to test two sets of experimental blades, the CX-100 and TX-100. The blade aerodynamic and structural characterization, meteorological inflow and wind turbine structural response will be monitored with an array of 75 instruments: 33 to characterize the blades, 15 to characterize the inflow, and 27 to characterize the time-varying state of the turbine. For both tests, data will be sampled at a rate of 30 Hz using the ATLAS II (Accurate GPS Time-Linked Data Acquisition System) data acquisition system. The system features a time-synchronized continuous data stream and telemetered data from the turbine rotor. This paper documents the instruments and infrastructure that have been developed to monitor these blades, turbines and inflow.

Formaldehyde emissions from industrial facilities in Houston, TX  

NASA Astrophysics Data System (ADS)

Formation of particulates and ozone in the urban environments is driven by the OH/HO2 radical chemistry. Consequently, it is critical to understand the OH/HO2 budget and to quantify radical precursors, such as HCHO. Recent modeling studies of the Houston area indicate that direct formaldehyde emissions are underestimated; and flares from petrochemical facilities were proposed as potential sources of HCHO. However, little is known about the possible HCHO emissions from different types of industrial facilities since accurate measurements are sparse, in part due to a lack of techniques that allow the fence-line detection of such emissions. Here we will present direct measurements of HCHO by an Imaging Differential Optical Absorption Spectroscopy instrument (I-DOAS) during the 2009 FLAIR/SHARP project in Houston, TX. I-DOAS, which will be described in detail, measures HCHO absorptions along 50 elevation viewing angles. By scanning in the azimuth direction, 2-D images of HCHO plume column densities can be derived. During the FLAIR project, the I-DOAS was deployed at different industrial facilities in the Houston area to visualize and quantify the emissions from industrial flares and smoke stacks. We will present first observations of HCHO plumes from burning flares and other industrial sources.

New analyses of two Algol systems - TX CET and RR TrA  

NASA Astrophysics Data System (ADS)

The photoelectric observations of TX Cet (by Duerbeck and Ammann in 1976) and RR TrA (by Somerville in 1961 - 1963) were reanalyzed with the Wilson and Devinney model. The inclinations were found to be very large, and the eclipses were found to be total and almost total for TX Cet and RR TrA, respectively. The photometric mass ratios are believed to be fairly reliable. Both of the two systems are found to have semidetached configurations with the lower-mass components filling their Roche lobes (regular Algol systems). It is found that TX Cet either does not have a third light at all or the third light is only marginally detectable. Masses and radii of components are estimated. It is suggested that TX Cet may be evolving from an evolved contact configuration, whereas RR TrA is at a stage well after the contact phase, where the mass gainer is now a normal main-sequence star.

Fate of the Biological Control Agent Pseudomonas aureofaciens TX-1 after Application to Turfgrass  

PubMed Central

The fate and impact of Pseudomonas aureofaciens TX-1 following application as a biocontrol agent for fungi in turfgrass were studied. The organism was applied with a modified irrigation system by using a preparation containing 1 106 P. aureofaciens TX-1 CFU ml?1 about 100 times between May and August. We examined the impact of this repeated introduction of P. aureofaciens TX-1 (which is known to produce the antimicrobial compound phenazine-1-carboxylic acid) on the indigenous microbial community of the turfgrass system and on establishment of introduced bacteria in the soil system. A PCR primer-DNA hybridization probe combination was developed to accurately monitor the fate of P. aureofaciens TX-1 following application in irrigation water. To assess the impact of frequent P. aureofaciens TX-1 applications on the indigenous bacterial community, turfgrass canopy, thatch, and rhizosphere samples were obtained during the growing season from control and treated plots and subjected to DNA extraction procedures and denaturing gradient gel electrophoresis (DGGE). PCR amplification and hybridization of extracted DNA with the P. aureofaciens TX-1-specific primer-probe combination revealed that P. aureofaciens TX-1 not only became established in the rhizosphere and thatch but also was capable of overwintering. Separation of PCR-amplified partial 16S rRNA genes by DGGE showed that the repeated application of P. aureofaciens TX-1 in irrigation water resulted in transient displacement of a leaf surface bacterial community member. There was no obvious alteration of any dominant members of the thatch and rhizosphere microbial communities.

Heteromtoxin (HmTx), a novel heterodimeric phospholipase A(2) from Heterometrus laoticus scorpion venom.  

PubMed

Heteromtoxin (HmTx) is a group III phospholipase A(2) produced in Heterometrus laoticus, in Thailand. In this study, HmTx was purified from venom by separation chromatography, and the PLA(2) activity of the fractions was determined by lecithin agar assay. The enzyme is an acidic protein with a pI of 5.6 and an apparent molecular weight of 14018.4 Da. The nucleotide sequence of HmTx contains 649 bp, and the mature protein is predicted to have 131 amino acid residues-104 of which make up the large subunit, and 27 of which make up the small subunit. The subunit structure of HmTx is highly similar to that of the other toxin, Pandinus imperator imperatoxin I (IpTx(i)) and to Mesobuthus tamulus phospholipase A(2) (MtPLA(2)). The 3D-structure of HmTx consists of three conserved alpha-helices: h1 (Lys24-His34), h2 (Cys59-Asp71), and h3 (Ala80-Phe89). The beta-sheet consisted of a single stranded anti-parallel beta-sheet (b1.1 at Glu43-Lys45 and b1.2 at Lys48-Asn50) that was highly similar to the conserved sequences (-CGXG-, -CCXXHDXC- and CXCEXXXXXC-) of Apis mellifera (bee) phospholipases.

Optimal Cleavage and Oxidative Folding of ?-Conotoxin TxIB as a Therapeutic Candidate Peptide  

PubMed Central

Alpha6beta2 nicotinic acetylcholine receptors (nAChRs) are potential therapeutic targets for the treatment of several neuropsychiatric diseases, including addiction and Parkinsons disease. Alpha-conotoxin (?-CTx) TxIB is a uniquely selective ligand, which blocks ?6/?3?2?3 nAChRs only, but does not block the other subtypes. Therefore, ?-CTx TxIB is a valuable therapeutic candidate peptide. Synthesizing enough ?-CTx TxIB with high yield production is required for conducting wide-range testing of its potential medicinal applications. The current study optimized the cleavage of synthesized ?-CTx TxIB resin-bounded peptide and folding of the cleaved linear peptide. Key parameters influencing cleavage and oxidative folding of ?-CTx TxIB were examined, such as buffer, redox agents, pH, salt, co-solvent and temperature. Twelve conditions were used for cleavage optimization. Fifty-four kinds of one-step oxidative solution were used to assess their effects on each ?-CTx TxIB isomers yield. The result indicated that co-solvent choices were particularly important. Completely oxidative folding of globular isomer was achieved when the NH4HCO3 or Tris-HCl folding buffer at 4 C contained 40% of co-solvent DMSO, and GSH:GSSG (2:1) or GSH only with pH 8~8.7.

Aerospace medicine at Brooks AFB, TX: hail and farewell.  

PubMed

With the impending termination of USAF operations at Brooks Air Force Base (AFB) in San Antonio, TX, it is time to consider its historic role in Aerospace Medicine. The base was established in 1917 as a flight training center for the U.S. Army Air Service and in 1926 became home to its School of Aviation Medicine. The school moved to San Antonio's Randolph Field in 1931, but in 1959 it returned to Brooks where it occupied new facilities to support its role as a national center for U.S. Air Force aerospace medicine, including teaching, clinical medicine, and research. The mission was then expanded to encompass support of U.S. military and civilian space programs. With the abrupt termination of the military space program in 1969, research at Brooks focused on clinical aviation medicine and support of advanced military aircraft while continuing close cooperation with NASA in support of orbital spaceflight and the journey to the Moon. Reorganization in the 1990s assigned all research functions at Brooks to the Human Systems Division and its successors, leaving to USAFSAM the missions related to clinical work and teaching. In 2002 the USAF and the city of San Antonio implemented shared operation of Brooks as a "City-Base" in the hope of deflecting threatened closure. Nevertheless, under continuing pressure to consolidate military facilities in the United States, the 2005 Base Closure and Realignment Commission ordered Brooks closed by 2011, with its aerospace medicine functions relocated to new facilities at Wright-Patterson AFB in Dayton, OH.

Cyclic AMP signaling stimulates proteasome degradation of thioredoxin interacting protein (TxNIP) in pancreatic beta-cells.  

PubMed

Thioredoxin interacting protein (TxNIP) functions as an effector of glucotoxicity in pancreatic beta-cells. Exendin-4 (Ex-4), a long-term effective GLP-1 receptor agonist, reduces TxNIP level in pancreatic beta-cells. Mechanisms underlying this reduction, however, remain largely unknown. We show here that Ex-4, 8-bromo-cAMP, the cAMP promoting agent forskolin, as well as activators of protein kinase A (PKA) and exchange protein activated by cAMP (Epac), all attenuated the effect of high glucose (20mM) on TxNIP level in the pancreatic beta-cell line Ins-1. Forskolin and Ex-4 also reduced TxNIP level in cultured primary rat islets. This repressive effect is at least partially mediated via stimulating proteasome-dependent TxNIP degradation, since the proteasomal inhibitor MG132, but not the lysosomal inhibitor chloroquine, significantly blocked the repressive effect of forskolin. Furthermore, forskolin enhanced TxNIP ubiquitination. Both PKA inhibition and Epac inhibition partially blocked the repressive effect of forskolin on TxNIP level. In addition, forskolin and Ex-4 protected Ins-1 cells from high glucose-induced apoptotic activity, assessed by measuring caspase 3 activity. Finally, knockdown of TxNIP expression led to reduced caspase 3 expression levels and blunted response to forskolin treatment. We suggest that proteasome-dependent TxNIP degradation is a novel mechanism by which Ex-4-cAMP signaling protects pancreatic beta cells. PMID:20385228

LyeTx I, a potent antimicrobial peptide from the venom of the spider Lycosa erythrognatha.  

PubMed

LyeTx I, an antimicrobial peptide isolated from the venom of Lycosa erythrognatha, known as wolf spider, has been synthesised and its structural profile studied by using the CD and NMR techniques. LyeTx I has shown to be active against bacteria (Escherichia coli and Staphylococcus aureus) and fungi (Candida krusei and Cryptococcus neoformans) and able to alter the permeabilisation of L: -alpha-phosphatidylcholine-liposomes (POPC) in a dose-dependent manner. In POPC containing cholesterol or ergosterol, permeabilisation has either decreased about five times or remained unchanged, respectively. These results, along with the observed low haemolytic activity, indicated that antimicrobial membranes, rather than vertebrate membranes seem to be the preferential targets. However, the complexity of biological membranes compared to liposomes must be taken in account. Besides, other membrane components, such as proteins and even specific lipids, cannot be discarded to be important to the preferential action of the LyeTx I to the tested microorganisms. The secondary structure of LyeTx I shows a small random-coil region at the N-terminus followed by an alpha-helix that reached the amidated C-terminus, which might favour the peptide-membrane interaction. The high activity against bacteria together with the moderate activity against fungi and the low haemolytic activity have indicated LyeTx I as a good prototype for developing new antibiotic peptides.

Minimal non-orthogonality rate 1 space-time block code for 3+ Tx antennas  

Microsoft Academic Search

We propose a full rate space-time block code for 3+ Tx antennas. The code is chosen to minimize the non-orthonormality that arises from increasing the rate above the maximum allowed by orthogonality. A linear decoding based on iterative interference cancellation between parts of the code approaches the maximal likelihood decoding performance

Interacting sites of scorpion toxin ErgTx1 with hERG1 K+ channels.  

PubMed

Peptides purified from scorpion venoms were shown to interact with specific amino acid residues present in the outer vestibule of various sub-types of potassium channels, occluding the pore and causing a decrement of K(+) permeability through the membrane of excitable and non excitable cells. This communication describes the identification of several interacting sites of toxin ErgTx1, a toxin purified from the venom of the scorpion Centruroides noxius, with the human ERG1 K(+) channels, by means of site-directed mutagenesis of specific residues of the toxin. Recombinant mutants of the gene coding for ErgTx1 were expressed heterologously in Escherichia coli, properly folded and their affinities and interactions with hERG1 channels were determined by patch-clamp techniques. Residues in position Y14, Y17 and F37 of the solvent exposed hydrophobic surface, and charged residues at the position K13 and K38 of ErgTx1 were shown to cause a decrement of the affinity from 20 folds to 3 orders of magnitude, thus suggesting that they are certainly participating on the binding surface of this toxin towards the hERG1 channels. Double mutants at positions K13 and F37, Y14 and F37, Y17 and F37 and K13 and K38 were also prepared and assayed, but the results obtained are not much different from the single point mutants of ErgTx1. The results of the present work indicate the most probable surface area of ErgTx1 that makes contact with the hERG channels. PMID:22366117

Inhibition of the myotoxic activity of Bothrops jararacussu venom and its two major myotoxins, BthTX-I and BthTX-II, by the aqueous extract of Tabernaemontana catharinensis A. DC. (Apocynaceae).  

PubMed

Partial neutralization of the myotoxic effect of Bothrops jararacussu venom (BV) and two of its myotoxins [bothropstoxin-I (BthTX-I), catalytically inactive, and II (BthTX-II), showing low PLA2 activity], by the lyophilized aqueous extract of Tabernaemontana catharinensis (AE), was studied in rat isolated soleus muscle preparations (in vitro) and through i.m. injection in the gastrocnemius muscle (in vivo) by determination of creatine kinase (CK) activity and histopathological analysis. Incubation of soleus muscle for 1 h with BV or toxins (20 microg/ml) plus AE (400 microg/ml) added immediately after BV, BthTX-I or BthTX-II reduced CK levels by 53%, 37% and 56%, respectively. The myonecrotic effects of BV (20 microg/ml) upon soleus muscle was reduced 24%, 35% and 36% when AE (400 microg/ml) was added 1 h after BV and CK was evaluated 30 min, 1 and 2 h later, respectively. For BthTX-I these values were 46%, 48% and 47%, while for BthTX-II no inhibitory effect was detected. Histological analysis of soleus muscle after incubation with AE (400 microg/ml, 1 h) did not reveal any change in muscle fibers, but severe necrosis induced by BV or toxins (20 microg/ml) was clearly in evidence, and decreased significantly when soleus muscle was protected by AE. This protection was also observed when AE was administered 1 h after BV or BthTX-I, but not after BthTX-II. AE did not inhibit the catalytic PLA2 activity of BthTX-II or BV and did not change the PAGE pattern of BV, BthTX-I or BthTX-II. In vivo assays were performed in 100-g rats and maximal CK release was attained at a dose of 100 microg of BV, 3 h after injection. AE was not effective when injected 20 s after BV or toxins. However, injecting BV or toxins (100 microg), which were pre-incubated with AE (2 mg) caused an inhibition of 57%, 59% and 51%, respectively, with zero time pre-incubation, but was less effective with 1 h pre-incubation. This plant represents a potential source of promising myotoxin inhibitors. PMID:15693719

BeKm-1 is a HERG-specific toxin that shares the structure with ChTx but the mechanism of action with ErgTx1.  

PubMed

Peptide toxins with disulfide-stabilized structures have been used as molecular calipers to probe the outer vestibule structure of K channels. We want to apply this approach to the human ether-a-go-go-related gene (HERG) channel, whose outer vestibule is unique in structure and function among voltage-gated K channels. Our focus here is BeKm-1, a HERG-specific peptide toxin that can suppress HERG in the low nM concentration range. Although BeKm-1 shares the three-dimensional scaffold with the well-studied charybdotoxin, the two use different mechanisms in suppressing currents through their target K channels. BeKm-1 binds near, but not inside, the HERG pore, and it is possible that BeKm-1-bound HERG channels can conduct currents although with markedly altered voltage-dependence and kinetics of gating. BeKm-1 and ErgTx1 differ in three-dimensional scaffold, but the two share mechanism of action and have overlapping binding sites on the HERG channel. For both, residues in the middle of the S5-P linker (the putative 583-597 helix) and residues at the pore entrance are critical for binding, although specific contact points vary between the two. Toxin foot printing using BeKm-1 and ErgTx1 will likely provide complementary information about the unique outer vestibule structure of the HERG channel. PMID:12719233

GOC-TX: A Reliable Ticket Synchronization Application for the Open Science Grid  

NASA Astrophysics Data System (ADS)

One of the major operational issues faced by large multi-institutional collaborations is permitting its users and support staff to use their native ticket tracking environment while also exchanging these tickets with collaborators. After several failed attempts at email-parser based ticket exchanges, the OSG Operations Group has designed a comprehensive ticket synchronizing application. The GOC-TX application uses web-service interfaces offered by various commercial, open source and other homegrown ticketing systems, to synchronize tickets between two or more of these systems. GOC-TX operates independently from any ticketing system. It can be triggered by one ticketing system via email, active messaging, or a web-services call to check for current sync-status, pull applicable recent updates since prior synchronizations to the source ticket, and apply the updates to a destination ticket. The currently deployed production version of GOC-TX is able to synchronize tickets between the Numara Footprints ticketing system used by the OSG and the following systems: European Grid Initiative's system Global Grid User Support (GGUS) and the Request Tracker (RT) system used by Brookhaven. Additional interfaces to the BMC Remedy system used by Fermilab, and to other instances of RT used by other OSG partners, are expected to be completed in summer 2010. A fully configurable open source version is expected to be made available by early autumn 2010. This paper will cover the structure of the GOC-TX application, its evolution, and the problems encountered by OSG Operations group with ticket exchange within the OSG Collaboration.

Unmasking Snake Venom of Bothrops leucurus: Purification and Pharmacological and Structural Characterization of New PLA2 Bleu TX-III  

PubMed Central

Bleu TX-III was isolated from Bothrops leucurus snake venom on one-step analytical chromatography reverse phase HPLC, was homogeneous on SDS-PAGE, and was confirmed by Q-Tof Ultima API ESI/MS (TOF MS mode) mass spectrometry in 14243.8?Da. Multiple alignments of Bleu TX-III show high degree of homology with basic PLA2 myotoxins from other Bothrops venoms. Our studies on local and systemic myotoxicity in vivo reveal that Bleu TX-III is myotoxin with local but not systemic action due to the decrease in the plasmatic CK levels when Bleu TX-III is administrated by intravenous route in mice (dose 1 and 5??g). And at a dose of 20??g myotoxin behaves like a local and systemic action. Bleu TX-III induced moderate marked paw edema, evidencing the local increase in vascular permeability. The inflammatory events induced in the mice (I.M.) were investigated. The increase in the levels of IL-1, IL-6, and TNF-? was observed in the plasma. It is concluded that Bleu TX-III induces inflammatory events in this model. The enzymatic phospholipid hydrolysis may be relevant to these phenomena. Bothrops leucurus venom is still not extensively explored, and the knowledge of its toxins separately through the study of structure/function will contribute for a better understanding of its action mechanism.

TxA2 inhibition and ischemia-induced loss of myocardial function and reactive hyperemia.  

PubMed

To determine the contribution of thromboxane (Tx) A2 release in reperfusion injury, 17 dogs were subjected to total coronary occlusion for 1 h and reperfusion for 1 h. Eleven dogs were treated with saline, and six were treated with selective TxA2 synthetase inhibitor U63,557A (5 mg/kg iv) 30 min before coronary artery occlusion. In all saline-treated dogs, peak reactive hyperemia after 10-s total coronary artery occlusion was diminished (P less than 0.01) after reperfusion. Myocardial segmental shortening was also reduced (9.8 +/- 1.9 to -6.7 +/- 2.0%, P less than 0.01) in the reperfused region. Reperfusion was associated with 737 +/- 343 premature ventricular contractions (PVCs) per hour. Histology revealed extensive myocardial infiltration and capillary plugging by leukocytes in the reperfused region. Myeloperoxidase, an index of leukocyte infiltration, was also increased (P less than 0.02) in the reperfused region. In the U63,557A-treated animals, serum and plasma TxB2 levels were markedly (P less than 0.02) reduced. Decrease in myocardial shortening fraction was less in U63,557A- than in saline-treated animals (P less than 0.05). The frequency of reperfusion PVCs was also significantly reduced (10 +/- 5 PVCs/h, P less than 0.02 compared with saline-treated dogs). However, peak reactive hyperemia was reduced similar to that in saline-treated dogs. Myocardial infiltration and capillary plugging by leukocytes in the reperfused regions was also similar in the U63,557A- and saline-treated dogs. These results indicate that treatment with U63,557A decreases reperfusion arrhythmias and preserves myocardial function. However, coronary reperfusion-induced deterioration in reactive hyperemia is not affected.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2159727

Tank 241-TX-104, cores 230 and 231 analytical results for the final report  

SciTech Connect

This document is the analytical laboratory report for tank 241-TX-104 push mode core segments collected between February 18, 1998 and February 23, 1998. The segments were subsampled and analyzed in accordance with the Tank 241-TX-104 Push Mode Core Sampling and Analysis Plan (TSAP) (McCain, 1997), the Data Quality Objective to Support Resolution of the Organic Complexant Safety Issue (Organic DQO) (Turner, et al., 1995) and the Safety Screening Data Quality Objective (DQO) (Dukelow, et.al., 1995). The analytical results are included in the data summary table. None of the samples submitted for Differential Scanning Calorimetry (DSC) and Total Alpha Activity (AT) exceeded notification limits as stated in the TSAP. The statistical results of the 95% confidence interval on the mean calculations are provided by the Tank Waste Remediation Systems Technical Basis Group in accordance with the Memorandum of Understanding (Schreiber, 1997) and are not considered in this report. Appearance and Sample Handling Attachment 1 is a cross reference to relate the tank farm identification numbers to the 222-S Laboratory LabCore/LIMS sample numbers. The subsamples generated in the laboratory for analyses are identified in these diagrams with their sources shown. Core 230: Three push mode core segments were removed from tank 241-TX-104 riser 9A on February 18, 1998. Segments were received by the 222-S Laboratory on February 19, 1998. Two segments were expected for this core. However, due to poor sample recovery, an additional segment was taken and identified as 2A. Core 231: Four push mode core segments were removed from tank 241-TX-104 riser 13A between February 19, 1998 and February 23, 1998. Segments were received by the 222-S Laboratory on February 24, 1998. Two segments were expected for this core. However, due to poor sample recovery, additional segments were taken and identified as 2A and 2B. The TSAP states the core samples should be transported to the laboratory within three calendar days from the time each segment is removed from the tank; this requirement was not met for the segments from Core 231.

Vapor space characterization of waste Tank 241-TX-118 (in situ): Results from samples collected on 9/7/94  

SciTech Connect

This report describes inorganic and organic analyses results from in situ samples obtained from the headspace of the Hanford waste storage Tank 241-TX-118 (referred to as Tank TX-118). The results described here were obtained to support safety and toxicological evaluations. A summary of the results for inorganic and organic analytes is listed in Table 1. Detailed descriptions of the results appear in the text. Quantitative results were obtained for the inorganic compounds ammonia (NH{sub 3}), nitrogen dioxide (NO{sub 2}), nitric oxide (NO), hydrogen cyanide (CHN), and water (H{sub 2}O). Sampling for sulfur oxides (SO{sub x}) was not requested. In addition, quantitative results were obtained for the 39 TO-14 compounds plus an additional 13 analytes. Hexane, normally included in the additional analytes, was removed because a calibration standard was not available during analysis of Tank TX-118 SUMMA{trademark} canisters. Of these, 12 were observed above the 5-ppbv reporting cutoff. Fourteen tentatively identified compounds (TICs) were observed above the reporting cutoff of (ca.) 10 ppbv and are reported with concentrations that are semiquantitative estimates based on internal-standard response factors. The 10 organic analytes with the highest estimated concentrations are listed in Table 1 and account for approximately 86% of the total organic components in Tank TX-118. Permanent gas analysis was not conducted on the tank-headspace samples. Tank TX-118 is on both the Ferrocyanide and Organic Watch List.

Chemical Modifications of PhTX-I Myotoxin from Porthidium hyoprora Snake Venom: Effects on Structural, Enzymatic, and Pharmacological Properties  

PubMed Central

We recently described the isolation of a basic PLA2 (PhTX-I) from Porthidium hyoprora snake venom. This toxin exhibits high catalytic activity, induces in vivo myotoxicity, moderates footpad edema, and causes in vitro neuromuscular blockade. Here, we describe the chemical modifications of specific amino acid residues (His, Tyr, Lys, and Trp), performed in PhTX-I, to study their effects on the structural, enzymatic, and pharmacological properties of this myotoxin. After chemical treatment, a single His, 4 Tyr, 7 Lys, and one Trp residues were modified. The secondary structure of the protein remained unchanged as measured by circular dichroism; however other results indicated the critical role played by Lys and Tyr residues in myotoxic, neurotoxic activities and mainly in the cytotoxicity displayed by PhTX-I. His residue and therefore catalytic activity of PhTX-I are relevant for edematogenic, neurotoxic, and myotoxic effects, but not for its cytotoxic activity. This dissociation observed between enzymatic activity and some pharmacological effects suggests that other molecular regions distinct from the catalytic site may also play a role in the toxic activities exerted by this myotoxin. Our observations supported the hypothesis that both the catalytic sites as the hypothetical pharmacological sites are relevant to the pharmacological profile of PhTX-I.

Monte Carlo modeling of a Novalis Tx Varian 6 MV with HD-120 multileaf collimator.  

PubMed

A Monte Carlo model of the Novalis Tx linear accelerator equipped with high-definition multileaf collimator (HD-120 HD-MLC) was commissioned using ionization chamber measurements in water. All measurements in water were performed using a liquid filled ionization chamber. Film measurements were made using EDR2 film in solid water. Open rectangular fields defined by the jaws or the HD-MLC were used for comparison against measurements. Furthermore, inter- and intraleaf leakage calculated by the Monte Carlo model was compared against film measurements. The statistical uncertainty of the Monte Carlo calculations was less than 1% for all simulations. Results for all regular field sizes show an excellent agreement with commissioning data (percent depth-dose curves and profiles), well within 1% of difference in the relative dose and 1 mm distance to agreement. The computed leakage through HD-MLCs shows good agreement with film measurements. The Monte Carlo model developed in this study accurately represents the new Novalis Tx Varian linac with HD-MLC and can be used for reliable patient dose calculations. PMID:22955663

Mapping the binding site of a human ether-a-go-go-related gene-specific peptide toxin (ErgTx) to the channel's outer vestibule.  

PubMed

The goals of this study are to investigate the mechanism and site of action whereby a human ether-a-go-go-related gene (HERG)-specific scorpion peptide toxin, ErgTx, suppresses HERG current. We apply cysteine-scanning mutagenesis to the S5-P and P-S6 linkers of HERG and examine the resulting changes in ErgTx potency. Data are compared with the characteristics of charybdotoxin (ChTx, or its analogs) binding to the Shaker channel. ErgTx binds to the outer vestibule of HERG but may not physically occlude the pore. In contrast to ChTx. Shaker interaction, elevating [K](o) (from 2 to 98 mm) does not affect ErgTx potency, and through-solution electrostatic forces only play a minor role in influencing ErgTx.HERG interaction. Cysteine mutations of three positions in S5-P linker (Trp-585, Gly-590, and Ile-593) and 1 position in P-S6 linker (Pro-632) induce profound changes in ErgTx binding (DeltaDeltaG > 2 kcal/mol). We propose that the long S5-P linker of the HERG channel forms an amphipathic alpha-helix that, together with the P-S6 linker, forms a hydrophobic ErgTx binding site. This study paves the way for future mutant cycle analysis of interacting residues in the ErgTx.HERG complex, which, in conjunction with NMR determination of the ErgTx solution structure, will yield information about the topology of HERG's outer vestibule.

The type B brevetoxin (PbTx-3) adversely affects development, cardiovascular function, and survival in Medaka (Oryzias latipes) embryos.  

PubMed Central

Brevetoxins are produced by the red tide dinoflagellate Karenia brevis. The toxins are lipophilic polyether toxins that elicit a myriad of effects depending on the route of exposure and the target organism. Brevetoxins are therefore broadly toxic to marine and estuarine animals. By mimicking the maternal route of exposure to the oocytes in finfish, we characterized the adverse effects of the type B brevetoxin brevetoxin-3 (PbTx-3) on embryonic fish development and survival. The Japanese rice fish, medaka (Oryzias latipes), was used as the experimental model in which individual eggs were exposed via microinjection to various known concentrations of PbTx-3 dissolved in an oil vehicle. Embryos injected with doses exceeding 1.0 ng/egg displayed tachycardia, hyperkinetic twitches in the form of sustained convulsions, spinal curvature, clumping of the erythrocytes, and decreased hatching success. Furthermore, fish dosed with toxin were often unable to hatch in the classic tail-first fashion and emerged head first, which resulted in partial hatches and death. We determined that the LD(50) (dose that is lethal to 50% of the fish) for an injected dose of PbTx-3 is 4.0 ng/egg. The results of this study complement previous studies of the developmental toxicity of the type A brevetoxin brevetoxin-1 (PbTx-1), by illustrating in vivo the differing affinities of the two congeners for cardiac sodium channels. Consequently, we observed differing cardiovascular responses in the embryos, wherein embryos exposed to PbTx-3 exhibited persistent tachycardia, whereas embryos exposed to PbTx-1 displayed bradycardia, the onset of which was delayed.

Antinociceptive effect of Brazilian armed spider venom toxin Tx3-3 in animal models of neuropathic pain.  

PubMed

Venoms peptides have produced exceptional sources for drug development to treat pain. In this study we examined the antinociceptive and side effects of Tx3-3, a peptide toxin isolated from Phoneutria nigriventer venom, which inhibits high-voltage-dependent calcium channels (VDCC), preferentially P/Q and R-type VDCC. We tested the effects of Tx3-3 in animal models of nociceptive (tail-flick test), neuropathic (partial sciatic nerve ligation and streptozotocin-induced diabetic neuropathy), and inflammatory (intraplantar complete Freund's adjuvant) pain. In the tail-flick test, both intrathecal (i.t.) and intracerebroventricular (i.c.v.) injection of Tx3-3 in mice caused a short-lasting effect (ED(50) and 95% confidence intervals of 8.8 [4.1-18.8] and 3.7 [1.6-8.4] pmol/site for i.t. and i.c.v. injection, respectively), without impairing motor functions, at least at doses 10-30 times higher than the effective dose. By comparison, ?-conotoxin MVIIC, a P/Q and N-type VDCC blocker derived from Conus magus venom, caused significant motor impairment at doses close to efficacious dose in tail flick test. Tx3-3 showed a long-lasting antinociceptive effect in neuropathic pain models. Intrathecal injection of Tx3-3 (30 pmol/site) decreased both mechanical allodynia produced by sciatic nerve injury in mice and streptozotocin-induced allodynia in mice and rats. On the other hand, i.t. injection of Tx3-3 did not alter inflammatory pain. Taken together, our data show that Tx3-3 shows prevalent antinociceptive effects in the neuropathic pain models and does not cause adverse motor effects at antinociceptive efficacious doses, suggesting that this peptide toxin holds promise as a novel therapeutic agent for the control of neuropathic pain. The Brazilian armed spider Tx3-3, a new P/Q and R-type calcium channel blocker, effectively alleviates allodynia in animal neuropathic pain models. PMID:21570770

Hydrology of Lake County, Florida  

USGS Publications Warehouse

Lake County includes a 1,150 square-mile area consisting of ridges, uplands, and valleys in central-peninsular Florida. About 32 percent of the county is covered by lakes, swamps, and marshes. Water requirements in 1970 averaged about 54 million gallons per day. About 85 percent of the water was obtained from wells; about 15 percent from lakes. The Floridan aquifer supplies almost all the ground water used in Lake County. Annual recharge to the Floridan aquifer averages about 7 inches over the county; runoff average 8.5 inches. The quality of ground and surface water in Lake County is in general good enough for most uses; however, the poor quality of Floridan-aquifer water in the St. John River Valley probably results from the upward movement of saline water along a fault zone. Surface water in Lake County is usually less mineralized than ground water but is more turbid and colored. (Woodard-USGS)

Harpalycin 2 inhibits the enzymatic and platelet aggregation activities of PrTX-III, a D49 phospholipase A2 from Bothrops pirajai venom  

PubMed Central

Background Harpalycin 2 (HP-2) is an isoflavone isolated from the leaves of Harpalyce brasiliana Benth., a snakeroot found in northeast region of Brazil and used in folk medicine to treat snakebite. Its leaves are said to be anti-inflammatory. Secretory phospholipases A2 are important toxins found in snake venom and are structurally related to those found in inflammatory conditions in mammals, as in arthritis and atherosclerosis, and for this reason can be valuable tools for searching new anti-phospholipase A2 drugs. Methods HP-2 and piratoxin-III (PrTX-III) were purified through chromatographic techniques. The effect of HP-2 in the enzymatic activity of PrTX-III was carried out using 4-nitro-3-octanoyloxy-benzoic acid as the substrate. PrTX-III induced platelet aggregation was inhibited by HP-2 when compared to aristolochic acid and p-bromophenacyl bromide (p-BPB). In an attempt to elucidate how HP-2 interacts with PrTX-III, mass spectrometry, circular dichroism and intrinsic fluorescence analysis were performed. Docking scores of the ligands (HP-2, aristolochic acid and p-BPB) using PrTX-III as target were also calculated. Results HP-2 inhibited the enzymatic activity of PrTX-III (IC50 11.34??0.28??g/mL) although it did not form a stable chemical complex in the active site, since mass spectrometry measurements showed no difference between native (13,837.34?Da) and HP-2 treated PrTX-III (13,856.12?Da). A structural analysis of PrTX-III after treatment with HP-2 showed a decrease in dimerization and a slight protein unfolding. In the platelet aggregation assay, HP-2 previously incubated with PrTX-III inhibited the aggregation when compared with untreated protein. PrTX-III chemical treated with aristolochic acid and p-BPB, two standard PLA2 inhibitors, showed low inhibitory effects when compared with the HP-2 treatment. Docking scores corroborated these results, showing higher affinity of HP-2 for the PrTX-III target (PDB code: 1GMZ) than aristolochic acid and p-BPB. HP-2 previous incubated with the platelets inhibits the aggregation induced by untreated PrTX-III as well as arachidonic acid. Conclusion HP-2 changes the structure of PrTX-III, inhibiting the enzymatic activity of this enzyme. In addition, PrTX-III platelet aggregant activity was inhibited by treatment with HP-2, p-BPB and aristolochic acid, and these results were corroborated by docking scores.

Preliminary tank characterization report for single-shell tank 241-TX-101: best-basis inventory  

SciTech Connect

This document is a preliminary Tank Characterization Report (TCR). It only contains the current best-basis inventory (Appendix D) for single-shell tank 241-TX-101. No TCRs have been previously issued for this tank, and current core sample analyses are not available. The best-basis inventory, therefore, is based on an engineering assessment of waste type, process flowsheet data, early sample data, and/or other available information. The Standard Inventories of Chemicals and Radionuclides in Hanford Site Tank Wastes describes standard methodology used to derive the tank-by-tank best-basis inventories. This preliminary TCR will be updated using this same methodology when additional data on tank contents become available.

[Comparative evaluation of the acceptability of a new estradiol gel TX11323(A) and a reference gel].  

PubMed

This randomized, crossed, single-blind study compared the acceptability and drying time of the new estradiol gel TX11323(A) (Estrva Gel, Laboratoire Thramex) to that of a reference gel (CEstrodose, Laboratories Besins-Iscovesco), in two phases. In phase 1, 48 healthy menopausal female volunteers applied 1.5 mg estradiol of each form of estradiol gel on the outer side of the arm for 8 days, with a free period of 7 days between the two treatments. Acceptability, evaluated by self-questionnaire and drying time for the two treatments were noted at day 1 and day 8. The second phase applied only to 16 subjects who followed the same therapeutic protocol, except that this time application was made on the antero-external side of the thighs. Only the subjectively and objectively quantified drying-time was taken into account. A significant difference was found in favor of TX11323(A) gel in terms of the following items: consistency, ease of application and penetration, quantity of gel to apply, sensation of lasting stickness. We note that 68.8% subjects prefer TX11323(A) gel and 27.1% prefer the reference gel (p = 0.001). The timed drying-time for TX11323(A) gel is significantly reduced, 40 to 50% on average depending on the phase, compared to that of the reference gel. The subjective evaluation of the subjects confirms this shorter drying time. PMID:8926345

Evaluation of PhTX-74 as subtype-selective inhibitor of GluA2-containing AMPA receptors.  

PubMed

The ?-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptors (AMPARs) are glutamate-gated cation channels that mediate fast excitatory synaptic transmission in the central nervous system. AMPARs are tetramers formed by homo- or heteromeric assembly of GluA1-4 subunits to produce multiple subtypes with varying biophysical properties. Polyamine toxins such as joro spider toxins, philanthotoxins (PhTXs), and argiotoxins are use-dependent ion channel blockers of AMPARs widely employed as highly potent antagonists of GluA2-lacking receptor subtypes. In addition to this use, recent findings have indicated that a philanthotoxin analog, PhTX-74, can distinguish among GluA2-containing AMPAR subtypes in the presence of the prototypical transmembrane AMPAR regulatory protein ?-2 (or stargazin). Thus, PhTX-74 may be of potential use in studies of the neurobiological role of GluA2-containing subtypes. We have evaluated the pharmacological profile of PhTX-74 and related polyamine toxins at homo- and heteromeric AMPARs in the presence and absence of ?-2. Determination of IC(50) values for inhibition of glutamate-evoked currents from Xenopus oocytes expressing recombinant homo- or heteromeric combinations of GluA1, GluA2, and GluA3 in the presence of ?-2 shows that PhTX-74 inhibits homomeric GluA1 and GluA3 receptors nonselectively, with IC(50) values in the nanomolar range (252-356 nM), and heteromeric GluA1/A2 and GluA2/A3 receptors nonselectively, with IC(50) values in the micromolar range (22 ?M). Thus, in contrast to earlier findings, we find that PhTX-74 cannot pharmacologically discriminate between GluA2-containing AMPAR subtypes. PMID:24220009

BcsTx3 is a founder of a novel sea anemone toxin family of potassium channel blocker.  

PubMed

Sea anemone venoms have become a rich source of peptide toxins which are invaluable tools for studying the structure and functions of ion channels. In this work, BcsTx3, a toxin found in the venom of a Bunodosoma caissarum (population captured at the Saint Peter and Saint Paul Archipelago, Brazil) was purified and biochemically and pharmacologically characterized. The pharmacological effects were studied on 12 different subtypes of voltage-gated potassium channels (K(V)1.1-K(V)1.6; K(V)2.1; K(V)3.1; K(V)4.2; K(V)4.3; hERG and Shaker IR) and three cloned voltage-gated sodium channel isoforms (Na(V)1.2, Na(V)1.4 and BgNa(V)1.1) expressed in Xenopus laevis oocytes. BcsTx3 shows a high affinity for Drosophila Shaker IR channels over rKv1.2, hKv1.3 and rKv1.6, and is not active on NaV channels. Biochemical characterization reveals that BcsTx3 is a 50 amino acid peptide crosslinked by four disulfide bridges, and sequence comparison allowed BcsTx3 to be classified as a novel type of sea anemone toxin acting on K(V) channels. Moreover, putative toxins homologous to BcsTx3 from two additional actiniarian species suggest an ancient origin of this newly discovered toxin family. PMID:23895459

Hydrology of Polk County, Florida  

USGS Publications Warehouse

Local water managers usually rely on information produced at the State and regional scale to make water-resource management decisions. Current assessments of hydrologic and water-quality conditions in Polk County, Florida, commonly end at the boundaries of two water management districts (South Florida Water Management District and the Southwest Florida Water Management District), which makes it difficult for managers to determine conditions throughout the county. The last comprehensive water-resources assessment of Polk County was published almost 40 years ago. To address the need for current countywide information, the U.S. Geological Survey began a 3?-year study in 2002 to update information about hydrologic and water-quality conditions in Polk County and identify changes that have occurred. Ground-water use in Polk County has decreased substantially since 1965. In 1965, total ground-water withdrawals in the county were about 350 million gallons per day. In 2002, withdrawals totaled about 285 million gallons per day, of which nearly 95 percent was from the Floridan aquifer system. Water-conservation practices mainly related to the phosphate-mining industry as well as the decrease in the number of mines in operation in Polk County have reduced total water use by about 65 million gallons per day since 1965. Polk County is underlain by three principal hydrogeologic units. The uppermost water-bearing unit is the surficial aquifer system, which is unconfined and composed primarily of clastic deposits. The surficial aquifer system is underlain by the intermediate confining unit, which grades into the intermediate aquifer system and consists of up to two water-bearing zones composed of interbedded clastic and carbonate rocks. The lowermost hydrogeologic unit is the Floridan aquifer system. The Floridan aquifer system, a thick sequence of permeable limestone and dolostone, consists of the Upper Floridan aquifer, a middle semiconfining unit, a middle confining unit, and the Lower Floridan aquifer. The Upper Floridan aquifer provides most of the water required to meet demand in Polk County. Data from about 300 geophysical and geologic logs were used to construct hydrogeologic maps showing the tops and thicknesses of the aquifers and confining units within Polk County. Thickness of the surficial aquifer system ranges from several feet thick or less in the extreme northwestern part of the county and along parts of the Peace River south of Bartow to more than 200 feet along the southern part of the Lake Wales Ridge in eastern Polk County. Thickness of the intermediate aquifer system/intermediate confining unit is highly variable throughout the county because of past erosional processes and sinkhole formation. Thickness of the unit ranges from less than 25 feet in the extreme northwestern part of the county to more than 300 feet in southwestern Polk County. The altitude of the top of the Upper Floridan aquifer in the county ranges from about 50 feet above National Geodetic Vertical Datum of 1929 (NGVD 29) in the northwestern part to more than 250 feet below NGVD 29 in the southern part. Water levels in the Upper Floridan aquifer fluctuate seasonally, increasing during the wet season (June through September) and decreasing during the rest of the year. Water levels in the Upper Floridan aquifer also can change from year to year, depending on such factors as pumpage and climatic variations. In the southwestern part of the county, fluctuations in water use related to phosphate mining have had a major impact on ground-water levels. Hydrographs of selected wells in southwestern Polk County show a general decline in water levels that ended in the mid-1970s. This water-level decline coincides with an increase in water use associated with phosphate mining. A substantial increase in water levels that began in the mid-1970s coincides with a period of decreasing water use in the county. Despite reductions in water use since 1970, howev

Biochemical Characterization and Pharmacological Properties of New Basic PLA2 BrTX-I Isolated from Bothrops roedingeri (Roedinger's Lancehead) Mertens, 1942, Snake Venom  

PubMed Central

BrTX-I, a PLA2, was purified from Bothrops roedingeri venom after only one chromatographic step using reverse-phase HPLC on ?-Bondapak C-18 column. A molecular mass of 14358.69?Da was determined by MALDI-TOF mass spectrometry. Amino acid analysis showed a high content of hydrophobic and basic amino acids as well as 14 half-cysteine residues. The total amino acid sequence was obtained using SwissProt database and showed high amino acid sequence identity with other PLA2 from snake venom. The amino acid composition showed that BrTX-I has a high content of Lys, Tyr, Gly, Pro, and 14 half-Cys residues, typical of a basic PLA2. BrTX-I presented PLA2 activity and showed a minimum sigmoidal behavior, reaching its maximal activity at pH 8.0, 3545C, and required Ca2+. In vitro, the whole venom and BrTX-I caused a neuromuscular blockade in biventer cervicis preparations in a similar way to other Bothrops species. BrTX-I induced myonecrosis and oedema-forming activity analyzed through injection of the purified BrTX-I in mice. Since BrTX-I exerts a strong proinflammatory effect, the enzymatic phospholipid hydrolysis might be relevant for these phenomena; incrementing levels of IL-1, IL-6, and TNF? were observed at 15?min, 30?min, one, two, and six hours postinjection, respectively.

Flavonoids inhibit the platelet TxA2 signalling pathway and antagonize TxA2 receptors (TP) in platelets and smooth muscle cells  

PubMed Central

What is already known about this subject Flavonoids are largely recognized as potential inhibitors of platelet function, through nonspecific mechanisms such as antioxidant activity and/or inhibition of several enzymes and signalling proteins. In addition, we, and few others, have shown that certain antiaggregant flavonoids may behave as specific TXA2 receptor (TP) ligands in platelets. Whether flavonoids interact with TP isoforms in other cell types is not known, and direct evidence that flavonoidTP interaction inhibits signalling downstream TP has not been shown. What this study adds This study first demonstrates that certain flavonoids behave as ligands for both TP isoforms, not only in platelets, but also in human myometrium and in TP-transfected HEK 293T cells. Differences in the effect of certain flavonoids in platelet signalling, induced by either U46619 or thrombin, suggest that abrogation of downstream TP signalling is related to their specific blockage of the TP, rather than to a nonspecific effect on tyrosine kinases or other signalling proteins. Aims Flavonoids may affect platelet function by several mechanisms, including antagonism of TxA2 receptors (TP). These TP are present in many tissues and modulate different signalling cascades. We explored whether flavonoids affect platelet TP signalling, and if they bind to TP expressed in other cell types. Methods Platelets were treated with flavonoids, or other selected inhibitors, and then stimulated with U46619. Similar assays were performed in aspirinized platelets activated with thrombin. Effects on calcium release were analysed by fluorometry and changes in whole protein tyrosine phosphorylation and activation of ERK 1/2 by Western blot analysis. The binding of flavonoids to TP in platelets, human myometrium and TP?- and TP?-transfected HEK 293T cells was explored using binding assays and the TP antagonist 3H-SQ29548. Results Apigenin, genistein, luteolin and quercetin impaired U46619-induced calcium mobilization in a concentration-dependent manner (IC50 1030 m). These flavonoids caused a significant impairment of U46619-induced platelet tyrosine phosphorylation and of ERK 1/2 activation. By contrast, in aspirin-treated platelets all these flavonoids, except quercetin, displayed minor effects on thrombin-induced calcium mobilization, ERK 1/2 and total tyrosine phosphorylation. Finally, apigenin, genistein and luteolin inhibited by >50% 3H-SQ29548 binding to different cell types. Conclusions These data further suggest that flavonoids may inhibit platelet function by binding to TP and by subsequent abrogation of downstream signalling. Binding of these compounds to TP occurs in human myometrium and in TP-transfected HEK 293T cells and suggests that antagonism of TP might mediate the effects of flavonoids in different tissues.

The novel hypoxic cytotoxin, TX-2098 has antitumor effect in pancreatic cancer; possible mechanism through inhibiting VEGF and hypoxia inducible factor-1{alpha} targeted gene expression  

SciTech Connect

Tumor hypoxia has been considered to be a potential therapeutic target, because hypoxia is a common feature of solid tumors and is associated with their malignant phenotype. In the present study, we investigated the antitumor effect of a novel hypoxic cytotoxin, 3-[2-hydroxyethyl(methyl)amino]-2-quinoxalinecarbonitrile 1,4-dioxide (TX-2098) in inhibiting the expression of hypoxia inducible factor-1{alpha} (HIF-1{alpha}), and consequently vascular endothelial cell growth factor (VEGF) expression in pancreatic cancer. The antitumor effects of TX-2098 under hypoxia were tested against various human pancreatic cancer cell lines using WST-8 assay. VEGF protein induced pancreatic cancer was determined on cell-free supernatant by ELISA. Moreover, nude mice bearing subcutaneously (s.c.) or orthotopically implanted human SUIT-2 were treated with TX-2098. Tumor volume, survival and expression of HIF-1 and associated molecules were evaluated in treatment versus control groups. In vitro, TX-2098 inhibited the proliferation of various pancreatic cancer cell lines. In s.c model, tumors from nude mice injected with pancreatic cancer cells and treated with TX-2098 showed significant reductions in volume (P < 0.01 versus control). Quantitative real-time reverse transcription-PCR analysis revealed that TX-2098 significantly inhibited mRNA expression of the HIF-1 associated molecules, VEGF, glucose transporter 1 and Aldolase A (P < 0.01 versus control). These treatments also prolong the survival in orthotopic models. These results suggest that the effect of TX-2098 in pancreatic cancer might be correlated with the expression of VEGF and HIF-1 targeted molecules. -- Highlights: Black-Right-Pointing-Pointer We designed and synthesized novel hypoxic cytoxin, TX-2098. Black-Right-Pointing-Pointer TX-2098 inhibited the proliferation of human pancreatic cancer cells than TPZ. Black-Right-Pointing-Pointer TX-2098 reduced VEGF protein level than TPZ. Black-Right-Pointing-Pointer TX-2098 inhibited mRNA expression of VEGF, GLUT1 and Aldolase A, not HIF-1{alpha}. Black-Right-Pointing-Pointer TX-2098 improved the survival in orthotopic SUIT-2 xenograft model.

Effects of Tityus serrulatus scorpion venom and its toxin TsTX-V on neurotransmitter uptake in vitro  

SciTech Connect

Scorpion neurotoxins targeting the Na{sub v} channel can be classified into two classes: {alpha}- and {beta}-neurotoxins and are reported as highly active in mammalian brain. In this work, we evaluate the effects of Tityus serrulatus venom (Ts venom) and its {alpha}-neurotoxin TsTX-V on {gamma}-aminobutyric acid (GABA), dopamine (DA) and glutamate (Glu) uptake in isolated rat brain synaptosomes. TsTX-V was isolated from Ts venom by ion exchange chromatography followed by reverse-phase (C18) high-performance liquid chromatography. Neither Ts venom nor TsTX-V was able to affect {sup 3}H-Glu uptake. On the other hand, Ts venom (0.13 {mu}g/mg) significantly inhibited both {sup 3}H-GABA and {sup 3}H-DA uptake ({approx} 50%). TsTX-V showed IC{sub 5} values of 9.37 {mu}M and 22.2 {mu}M for the inhibition of {sup 3}H-GABA and {sup 3}H-DA uptake, respectively. These effects were abolished by pre-treatment with tetrodotoxin (TTX, 1 {mu}M), indicating the involvement of voltage-gated Na{sup +} channels in this process. In the absence of Ca{sup 2+}, and at low Ts venom concentrations, the reduction of {sup 3}H-GABA uptake was not as marked as in the presence of Ca{sup 2+}. TsTX-V did not reduce {sup 3}H-GABA uptake in COS-7 cells expressing the GABA transporters GAT-1 and GAT-3, suggesting that this toxin indirectly reduces the transport. The reduced {sup 3}H-GABA uptake by synaptosomes might be due to rapid cell depolarization as revealed by confocal microscopy of C6 glioma cells. Thus, TsTX-V causes a reduction of {sup 3}H-GABA and {sup 3}H-DA uptake in a Ca{sup 2+}-dependent manner, not directly affecting GABA transporters, but, in consequence of depolarization, involving voltage-gated Na{sup +} channels.

The final 112-frame movie of the 43 GHz SiO masers around the Mira Variable TX Cam  

NASA Astrophysics Data System (ADS)

The proximity of the SiO masers to the star, makes them a powerful tool for studying the properties of the extended stellar atmosphere. This project is a long monitoring campaign of the 43 GHz SiO masers (v=1 J=1->0) around the Mira Variable TX Cam. The target source was observed with the Very Long Baseline Array (VLBA) from the 24 th of May 1997 to the 25 th of January 2002 in bi-weekly or monthly intervals, covering 3.06 stellar cycles. The time-span and frequency of observations helped us examine the long and short-term properties of the emission and study the dynamics of the gas, the existence of shock waves and their contribution to the morphology and kinematics. Maps from each epoch were concatenated into a 112-frame movie showing the evolution of the emission around TX Cam.

Radical Budget and Ozone Production in Houston, TX during SHARP 2009  

NASA Astrophysics Data System (ADS)

The chemistry of atmospheric radicals, especially the hydroxyl radical (OH) and hydroperoxyl radical (HO2), together called HOx, is deeply involved in the formation of the secondary pollutants ozone and fine particles. Radical precursors such as nitrous acid (HONO) and formaldehyde (HCHO) significantly affects HOx budget in urban environments like Houston. These chemical processes connect surface emissions, both human and natural, to local and regional pollution, and climate change. Using the data collected during the Study of Houston Atmospheric Radical Precursors (SHARP) in Houston, TX in spring 2009, we test our understanding of photochemistry through the analysis of the radical budget and ozone production. A numerical box model was used to simulate the oxidation processes and observed OH and HO2 during this study. Using the model results, we calculate the radical budget and analyze the sensitivity of ozone production to nitrogen oxides (NOx) and volatile organic compounds (VOCs). The radical budget shows that the photolysis of HONO and the photolysis of HCHO were significant HOx sources in this urban environment. We also compare the observed OH reactivity and ozone production rate to the model calculations. In general, ozone production rate was VOC limited in the morning and NOx limited in the afternoon. This relationship results from the ratio of VOCs to NOx in Houston. Results from this study provide additional support for regulatory actions to reduce reactive VOCs in Houston in order to reduce ozone and other secondary pollutants.

Impacts of Hurricane Ike on the beaches of the Bolivar Peninsula, TX, USA  

NASA Astrophysics Data System (ADS)

Hurricane Ike caused substantial beach erosion along the coast of the Bolivar Peninsula, TX. Much of the erosion was caused by the offshore (ebb) flow of the ca. 5 m storm surge that formed spatially discrete scour features. Using aerial photography and repeat LiDAR data, we identify five types of scour features and describe the alongshore distribution in four flow environments. Type 1 scours are relatively small and compact features associated mainly with flow off a wide, vegetated (grasses, shrubs, trees) surface across a wide beach. Type 2 scours are large and branching forms associated mainly with flow that was channeled by streets or gaps between structures. Type 3 scours are large and blocky features associated with flow off a marsh surface, across a highway, which removed almost all beach sands from the surface. Type 4 scours are elongated, shore perpendicular channels associated with the same flow characteristics as Type 3 scours. Type 5 scours are elongated, shore-perpendicular features, sometimes branching, associated with flow through gaps in a destroyed shore protection structure. Repeat imagery indicates that many of the features persisted for at least seven months. Recent aerial photography indicates that aspects of some features remained evident more than three years after Ike's landfall.

T-x frequency filtering of high resolution seismic reflection data using singular spectral analysis  

NASA Astrophysics Data System (ADS)

We develop here an efficient approach using singular spectral analysis (SSA) for frequency filtering of seismic reflection data in t-x domain. The abrupt change in geophysical records creates ringing artifacts in the Fourier based filtering operations. We use here complete data adaptive basis functions in SSA filtering, which enables the self-similarity of the data in reconstruction of such sudden changes. We first tested the SSA based filtering algorithm on synthetic seismic data and then applied to real seismic reflection data from Singareni coalfields, Andhra Pradesh, India. The individual trace from each channel in the shot gathers is processed and compared with Fourier and multichannel SSA filtered output. Our analysis demonstrates that SSA filtering attenuated the low frequency ground role and high frequency noise embedded in the seismic record in a more efficient way than the other two methods. The coal formations and faults identified in the stack section of filtered data match quite well with the geological information available in the study region.

Research on Characteristics of Field Uniformity in Reverberation Chamber Using Two TX Antennas  

NASA Astrophysics Data System (ADS)

This paper presents a method to improve field uniformity using two TX antennas in a reverberation chamber with less steps of a stirrer. A mode-stirred reverberation chamber (MSRC) is considered as an alternative to the semi-anechoic chamber for an electromagnetic compatibility test because it provides a large test volume, a statistically uniform field, and a high maximum electric field. To improve field uniformity, we introduce two transmitting antennas for excitation in an MSRC, and predict statistical distribution of the complex reflection coefficients (scattering parameters). To prove the validation of our theory and the reliability of measurement results, three kinds of stirrers with different shape and sizes were fabricated and their efficiencies were measured in an MSRC, and then field uniformities have been investigated for 1-3GHz frequency within the maximum number of independent samples that stirrers can provide. The measurement results show that the average received power is about 1.5 times as high as when using one transmitting antenna, and field uniformity is improved. Use of two transmitting antennas in an MSRC is regarded as a useful method to improve field uniformity at less stirrer steps, for radiated immunity tests.

HONO Vertical Gradients during the 2006 TRAMP and the 2009 SHARP experiments in Houston, TX  

NASA Astrophysics Data System (ADS)

Nitrous acid (HONO) plays a significant role in tropospheric photochemistry as a precursor of the hydroxyl radical (OH). Despite the importance of HONO photolysis for the OH budget in the early morning, HONO formation mechanisms are not yet fully understood. In addition, recent observations of higher than expected daytime HONO concentrations are currently unexplained. The vertical distribution of HONO in the morning and during the day can have a considerable impact on its importance for ozone formation in the boundary layer. The observation of vertical profiles is also important to allow a better understanding of HONO formation in the atmosphere. Consequently there is an urgent need to provide observations and detailed model calculations of vertical HONO profiles. During the 2009 SHARP experiment from April 15 to May 29, 2009 in Houston, TX, we performed measurements of HONO, NO2, O3 and other trace gases in three altitude intervals (30-70m, 70 - 130m, and 130 - 300m), using UCLAs long path DOAS instrument. Vertical gradients of all atmospheric trace gases were frequently observed during stable nights. HONO established negative gradients, with higher concentrations near the ground, indicating that the source of HONO is at or near the ground. Daytime HONO gradients were also observed during some days. Here we compare our results with observations made at the same location in 2006 and with results from a 1-D chemical transport model to elucidate the mechanisms forming HONO in urban areas.

Protocols for Implementing an Escherichia coli Based TX-TL Cell-Free Expression System for Synthetic Biology  

PubMed Central

Ideal cell-free expression systems can theoretically emulate an in vivo cellular environment in a controlled in vitro platform.1 This is useful for expressing proteins and genetic circuits in a controlled manner as well as for providing a prototyping environment for synthetic biology.2,3 To achieve the latter goal, cell-free expression systems that preserve endogenous Escherichia coli transcription-translation mechanisms are able to more accurately reflect in vivo cellular dynamics than those based on T7 RNA polymerase transcription. We describe the preparation and execution of an efficient endogenous E. coli based transcription-translation (TX-TL) cell-free expression system that can produce equivalent amounts of protein as T7-based systems at a 98% cost reduction to similar commercial systems.4,5 The preparation of buffers and crude cell extract are described, as well as the execution of a three tube TX-TL reaction. The entire protocol takes five days to prepare and yields enough material for up to 3000 single reactions in one preparation. Once prepared, each reaction takes under 8 hr from setup to data collection and analysis. Mechanisms of regulation and transcription exogenous to E. coli, such as lac/tet repressors and T7 RNA polymerase, can be supplemented.6 Endogenous properties, such as mRNA and DNA degradation rates, can also be adjusted.7 The TX-TL cell-free expression system has been demonstrated for large-scale circuit assembly, exploring biological phenomena, and expression of proteins under both T7- and endogenous promoters.6,8 Accompanying mathematical models are available.9,10 The resulting system has unique applications in synthetic biology as a prototyping environment, or "TX-TL biomolecular breadboard."

Peripheral nerve sheath tumors from patients with neurofibromatosis type 1 do not have the chromosomal translocation t(X;18).  

PubMed

Neurofibromatosis type 1 (NF1) is a common autosomal dominant genetic disorder that is caused by a mutation in the NF1 gene. Hallmark characteristics include dermal neurofibromas, caf-au-lait spots, and learning disabilities. In approximately 25% of NF1 cases, plexiform neurofibromas, or peripheral nerve sheath tumors (PNSTs) that involve large segments of nerve sheath and nerve root, can form, of which a small percentage become malignant (MPNST). Most MPNSTs are composed of spindled neoplastic cells, and they can resemble other spindle-cell sarcomas, including leiomyosarcoma and monophasic synovial sarcoma. Histological diagnosis of MPNST is not always straightforward, and various immunohistochemical and molecular adjuncts can be critical in establishing a correct diagnosis. One example of genetic testing is the assay for the t(X;18) chromosomal translocation, which has been found to be common in synovial sarcomas. The aim of this study was to determine whether MPNSTs contain the t(X;18) chromosomal translocation. To detect the t(X;18) translocation product, SYT-SSX, total RNA was extracted from frozen archival tumors (15 dermal neurofibromas, 4 plexiform neurofibromas, and 7 MPNSTs) using Trizol. The RNA was then subjected to reverse-transcriptase polymerase chain reaction (RT-PCR) to specifically amplify SYT-SSX. None of the dermal neurofibromas, plexiform neurofibromas, or MPNSTs analyzed were positive for SYT-SSX mRNA. The results indicate that the t(X;18) translocation is absent in neurofibromas and is not a marker for MPNST in patients with NF1. PMID:11910511

Three-dimensional structure of conotoxin tx3a: An m-1 branch peptide of the M-superfamily.  

PubMed

The M-superfamily, one of eight major conotoxin superfamilies found in the venom of the cone snail, contains a Cys framework with disulfide-linked loops labeled 1, 2, and 3 (-CC (1) C (2) C (3) CC-). M-Superfamily conotoxins can be divided into the m-1, -2, -3, and -4 branches, based upon the number of residues located in the third Cys loop between the fourth and fifth Cys residues. Here we provide a three-dimensional solution structure for the m-1 conotoxin tx3a found in the venom of Conus textile. The 15-amino acid peptide, CCSWDVCDHPSCTCC, has disulfide bonds between Cys (1) and Cys (14), Cys (2) and Cys (12), and Cys (7) and Cys (15) typical of the C1-C5, C2-C4, and C3-C6 connectivity pattern seen in m-1 branch peptides. The tertiary structure of tx3a was determined by two-dimensional (1)H NMR in combination with the combined assignment and dynamics algorithm for nuclear magnetic resonance (NMR) applications CYANA program. Input for structure calculations consisted of 62 inter- and intraproton, five phi angle, and four hydrogen bond constraints. The root-mean-square deviation values for the 20 final structures are 0.32 +/- 0.07 and 0.84 +/- 0.11 A for the backbone and heavy atoms, respectively. Surprisingly, the structure of tx3a has a "triple-turn" motif seen in the m-2 branch conotoxin mr3a, which is absent in mr3e, the only other member of the m-1 branch of the M-superfamily whose structure is known. Interestingly, injection of tx3a into mice elicits an excitatory response similar to that of the m-2 branch peptide mr3a, even though the conotoxins have different disulfide connectivity patterns.

Biochemical, Pharmacological, and Structural Characterization of New Basic PLA2 Bbil-TX from Bothriopsis bilineata Snake Venom  

PubMed Central

Bbil-TX, a PLA2, was purified from Bothriopsis bilineata snake venom after only one chromatographic step using RP-HPLC on ?-Bondapak C-18 column. A molecular mass of 14243.8?Da was confirmed by Q-Tof Ultima API ESI/MS (TOF MS mode) mass spectrometry. The partial protein sequence obtained was then submitted to BLASTp, with the search restricted to PLA2 from snakes and shows high identity values when compared to other PLA2s. PLA2 activity was presented in the presence of a synthetic substrate and showed a minimum sigmoidal behavior, reaching its maximal activity at pH 8.0 and 2537C. Maximum PLA2 activity required Ca2+ and in the presence of Cd2+, Zn2+, Mn2+, and Mg2+ it was reduced in the presence or absence of Ca2+. Crotapotin from Crotalus durissus cascavella rattlesnake venom and antihemorrhagic factor DA2-II from Didelphis albiventris opossum sera under optimal conditions significantly inhibit the enzymatic activity. Bbil-TX induces myonecrosis in mice. The fraction does not show a significant cytotoxic activity in myotubes and myoblasts (C2C12). The inflammatory events induced in the serum of mice by Bbil-TX isolated from Bothriopsis bilineata snake venom were investigated.

Vapor space characterization of waste tank 241-TX-118: Results from samples collected on 12/16/94  

SciTech Connect

This report describes inorganic and organic analyses results from samples obtained from the headspace of the Hanford waste storage Tank 241-TX-118 (referred to as Tank TX-118). The results described here were obtained to support safety and toxicological evaluations. A summary of the results for inorganic and organic analytes is listed in Table 1. Detailed descriptions of the results appear in the text. Quantitative results were obtained for the inorganic compounds ammonia (NH{sub 3}), nitrogen dioxide (NO{sub 2}), nitric oxide (NO), and water (H{sub 2}O). Sampling for hydrogen cyanide (HCN) and sulfur oxides (SO{sub x}) was not requested. In addition, quantitative results were obtained for the 39 TO-14 compounds plus an additional 14 analytes. Of these, 3 were observed above the 5-ppbv reporting cutoff. Twenty three organic tentatively identified compounds (TICs) were observed above the reporting cutoff of (ca.) 10 ppbv, and are reported with concentrations that are semiquantitative estimates based on internal-standard response factors. The 10 organic analytes with the highest estimated concentrations are listed in Table 1 and account for approximately 84% of the total organic components in Tank TX-118. Two permanent gases, carbon dioxide (CO{sub 2}) and nitrous oxide (N{sub 2}O), were also detected.

Recombinant expression of the toxic peptide ErgTx1 and role of Met35 on its stability and function.  

PubMed

Ergtoxin 1 (ErgTx1) is a 42 amino acid peptide purified from the venom of the Mexican scorpion Centruroides noxius Hoffmann, capable of blocking specifically human potassium channels of the ether--go-go-related gene family (hERG). This peptide binds to a partially overlapping site on the channel outer mouth, in which residues of the S5-P linker are critically involved. Here we describe results of site directed mutagenesis of the ErgTx1 gene and its heterologous expression in Escherichia coli. The recombinant products show the fundamental role played by methionine in position 35 (Met35) of the primary structure. Naturally oxidized Met35 decreases by three orders of magnitude the affinity of the peptide for the hERG1 channels. This result is quite relevant, because it shows two possible situations: either Met35 is involved in the proper folding of the molecule or it plays a direct role in the interaction with the channel, i.e., constitutes part of the interacting surfaces. These two situations were evaluated by preparing heterologously expressed ErgTx1 gene and a mutant containing alanine in position 35. Additionally circular dichroism measurements of both native and recombinant peptides were performed. The electrophysiological recordings and the structural values obtained by optical measurements, strongly support the idea that Met35 is indeed a key residue on the interacting surfaces of the toxin with the channels.

Electrochemical and optical study of carotenoids in TX 100 micelles: Electron transfer and a large blue shift  

SciTech Connect

The first oxidation waves of 8{prime}-apo-{beta}-caroten-8{prime}-al (I) and 8{prime}-apo-{beta}-caroten-8{prime}nitrile (II) in TX100 micelles are clearly observed in their cyclic voltammograms (CVs). The CV of {beta}-carotene (III) in TX100 micelles shows that III is not oxidized. It is proposed that the hydrophobic barrier of the micelle is an important reason for the failure to oxidize III, which is totally located in the hydrophobic center of the micelle. The oxidation of I and II demonstrates that electrons can be transferred through the terminal groups over a distance of ca. 22 {angstrom}. An unusually large blue band shift (100 nm, relative to that in CH{sub 2}Cl{sub 2}) is observed in the optical absorption spectrum of 7{prime}-apo-7{prime},7{prime}-dicyano-{beta}-carotene (IV) in TX100 micelles. This phenomenon is not observed in the absorption spectra of other studied carotenoids. A change in the ground-state electronic structure of IV, due to the influence of water near the terminal dicyanomethylidene group, is proposed to be the major reason for this large band shift.

The receptor site of the spider toxin PcTx1 on the proton-gated cation channel ASIC1a  

PubMed Central

Acid-sensing ion channels (ASICs) are excitatory neuronal cation channels, involved in physiopathological processes related to extracellular pH fluctuation such as nociception, ischaemia, perception of sour taste and synaptic transmission. The spider peptide toxin psalmotoxin 1 (PcTx1) has previously been shown to inhibit specifically the proton-gated cation channel ASIC1a. To identify the binding site of PcTx1, we produced an iodinated form of the toxin (125I-PcTx1YN) and developed a set of binding and electrophysiological experiments on several chimeras of ASIC1a and the PcTx1-insensitive channels ASIC1b and ASIC2a. We show that 125I-PcTx1YN binds specifically to ASIC1a at a single site, with an IC50 of 128 pm, distinct from the amiloride blocking site. Results obtained from chimeras indicate that PcTx1 does not bind to ASIC1a transmembrane domains (M1 and M2), involved in formation of the ion pore, but binds principally on both cysteine-rich domains I and II (CRDI and CRDII) of the extracellular loop. The post-M1 and pre-M2 regions, although not involved in the binding site, are crucial for the ability of PcTx1 to inhibit ASIC1a current. The linker domain between CRDI and CRDII is important for their correct spatial positioning to form the PcTx1 binding site. These results will be useful for the future identification or design of new molecules acting on ASICs.

Structural and functional consequences of the presence of a fourth disulfide bridge in the scorpion short toxins: solution structure of the potassium channel inhibitor HsTX1.  

PubMed Central

We have determined the three-dimensional structure of the potassium channel inhibitor HsTX1, using nuclear magnetic resonance and molecular modeling. This protein belongs to the scorpion short toxin family, which essentially contains potassium channel blockers of 29 to 39 amino acids and three disulfide bridges. It is highly active on voltage-gated Kv1.3 potassium channels. Furthermore, it has the particularity to possess a fourth disulfide bridge. We show that HsTX1 has a fold similar to that of the three-disulfide-bridged toxins and conserves the hydrophobic core found in the scorpion short toxins. Thus, the fourth bridge has no influence on the global conformation of HsTX1. Most residues spatially analogous to those interacting with voltage-gated potassium channels in the three-disulfide-bridged toxins are conserved in HsTX1. Thus, we propose that Tyr21, Lys23, Met25, and Asn26 are involved in the biological activity of HsTX1. As an additional positively charged residue is always spatially close to the aromatic residue in toxins blocking the voltage-gated potassium channels, and as previous mutagenesis experiments have shown the critical role played by the C-terminus in HsTX1, we suggest that Arg33 is also important for the activity of the four disulfide-bridged toxin. Docking calculations confirm that, if Lys23 and Met25 interact with the GYGDMH motif of Kv1.3, Arg33 can contact Asp386 and, thus, play the role of the additional positively charged residue of the toxin functional site. This original configuration of the binding site of HsTX1 for Kv1.3, if confirmed experimentally, offers new structural possibilities for the construction of a molecule blocking the voltage-gated potassium channels.

Comparison of estimates of airmass aging using particle and other measurements near Fort Worth, TX  

NASA Astrophysics Data System (ADS)

The composition, concentration, and size of submicron aerosols were measured with a time resolution of five minutes by an Aerodyne high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) at a rural location northwest of the Dallas-Fort Worth, TX, area for the month of June 2011. A TSI, Inc., Model AE51 aethalometer using an optical absorption technique also was deployed to measure black carbon (BC) concentrations. The total measured PM1 mass concentration ranged between 1.0 microg/m3 and 17.1 microg/m3, with a mean and standard deviation of 4.6+/- 2.7 microg/m3. Significant variability is observed in the time series of total PM1 and of all four HR-ToF-AMS species, particularly between June 21 and 25. The average aerosol composition was dominated by organic matter (52.1 +/- 14.8%) and sulfate (28.8 +/- 11.8%). Organic aerosol concentrations were positively correlated with tracers of combustion carbon monoxide (CO) and BC, the coefficients of determination were r2=064 and r2=0.48, respectively. Because of the large influence of organics on total aerosol concentration, organic data were analyzed in the context of DeltaOA/DeltaCO, which typically is used to investigate the relative importance of secondary organic aerosol. The average DeltaOA/DeltaCO for the data used was 64.0 +/- 26.9 microg/ (m3 ppmv), which is typical of an aged air mass. Other metrics of age include the ratio of OOAI (more oxidized) to total oxidized organic aerosol (OOA), the ratio of sulfate to total sulfur, the ratio of its oxidation products to isoprene, and the ratio of nitrogen oxides to total reactive nitrogen. All metrics point to aged air masses, but variations in these age matrices, particularly during one period of enhanced DeltaOA/DeltaCO, help elucidate the contributions of various precursors and processes to organic aerosols at the site.

Complete genome sequence of Enterococcus faecium strain TX16 and comparative genomic analysis of Enterococcus faecium genomes  

PubMed Central

Background Enterococci are among the leading causes of hospital-acquired infections in the United States and Europe, with Enterococcus faecalis and Enterococcus faecium being the two most common species isolated from enterococcal infections. In the last decade, the proportion of enterococcal infections caused by E. faecium has steadily increased compared to other Enterococcus species. Although the underlying mechanism for the gradual replacement of E. faecalis by E. faecium in the hospital environment is not yet understood, many studies using genotyping and phylogenetic analysis have shown the emergence of a globally dispersed polyclonal subcluster of E. faecium strains in clinical environments. Systematic study of the molecular epidemiology and pathogenesis of E. faecium has been hindered by the lack of closed, complete E. faecium genomes that can be used as references. Results In this study, we report the complete genome sequence of the E. faecium strain TX16, also known as DO, which belongs to multilocus sequence type (ST) 18, and was the first E. faecium strain ever sequenced. Whole genome comparison of the TX16 genome with 21 E. faecium draft genomes confirmed that most clinical, outbreak, and hospital-associated (HA) strains (including STs 16, 17, 18, and 78), in addition to strains of non-hospital origin, group in the same clade (referred to as the HA clade) and are evolutionally considerably more closely related to each other by phylogenetic and gene content similarity analyses than to isolates in the community-associated (CA) clade with approximately a 34% average nucleotide sequence difference between the two clades at the core genome level. Our study also revealed that many genomic loci in the TX16 genome are unique to the HA clade. 380 ORFs in TX16 are HA-clade specific and antibiotic resistance genes are enriched in HA-clade strains. Mobile elements such as IS16 and transposons were also found almost exclusively in HA strains, as previously reported. Conclusions Our findings along with other studies show that HA clonal lineages harbor specific genetic elements as well as sequence differences in the core genome which may confer selection advantages over the more heterogeneous CA E. faecium isolates. Which of these differences are important for the success of specific E. faecium lineages in the hospital environment remain(s) to be determined.

Occurrence of metallothionein gene smtA in synechococcus Tx-20 and other blue-green algae

Blue-green algae are often abundant at Zn- and Cd-contaminated sites. In order to understand the mechanisms associated with Zn- and Cd-tolerance, we have isolated a metallothionein gene, designated smtA, in Synechococcus Tx-20 (- Pcc 6301 - Anacystis nidulans), a strain apparently obtained from an unpolluted site. The gene was cloned and sequenced, and its expression investigated in a range of heavy-metal-tolerant strains of the same organism obtained by stepwise adaptation. The polymerase chain reaction was used to probe for the possible presence of the homologous gene in a range of other strains (especially Synechococcus) isolated from sites without and with heavy metal contamination.

Data Package for Calendar Year 2002 RCRA Groundwater Monitoring Wells at Single-Shell Tank Waste Management Area TX-TY  

SciTech Connect

Two new RCRA groundwater monitoring wells were installed at the single-shell tank farm at Waste Management Area TX-TY in October and November 2002. This document provides the information on drilling and construction of these wells. Two new Resource Conservation and Recovery Act (RCRA) groundwater monitoring wells were installed at the single-shell tank farm Waste Management Area (WMA) TX-TY in October and November 2002 in fulfillment of Tri-Party Agreement (Ecology et al. 1998) Milestone M-24-00N. The well names are 299-W14-19 and 299-W15-44; the corresponding well numbers are C3957 and C3956, respectively. Well 299-W14-19 is located east of the central part of the TX Tank Farm and is a downgradient well filling a gap in the monitoring network between wells 299-W14-14 and 299-W14-6. Well 299-W15-44 is located at the southwest corner of the TX Tank Farm in an area where groundwater flow has been artificially altered toward the southwest by the 200-ZP-1 Operable Unit pump-and-treat system. The well is in the cone of depression of the 200-ZP-1 extraction wells and is downgradient of WMA TX-TY. The locations of all wells in the WMA TX-TY monitoring network are shown on Figure 1. The original assessment monitoring plan for WMA TX-TY was issued in 1993 (Caggiano and Chou 1993). That plan was updated for the continued assessment at WMA TX-TY in 2001 (Hodges and Chou 2001). The updated plan provides justification for the new wells. The new wells were constructed to the specifications and requirements described in Washington Administrative Code (WAC) 173-160 and WAC 173-303, the updated assessment plan for WMA TX-TY (Hodges and Chou 2001), and the description of work for well drilling and construction. This document compiles information on the drilling and construction, geophysical logging, and sediment and groundwater sampling applicable to the installation of wells 299-W14-19 and 299-W15-44. The information on drilling and construction, well development, and pump installation is summarized from CP-14265. Appendix A contains the Well Summary Sheets (as-built diagrams), the Well Construction Summary Reports, and the geologist's logs; Appendix B contains results of physical properties testing; Appendix C contains the analytical results from groundwater samples obtained during drilling; and Appendix D contains borehole geophysical logs.

Chromosomal translocation t(X;18) in human synovial sarcomas analyzed by fluorescence in situ hybridization using paraffin-embedded tissue.  

PubMed Central

Synovial sarcoma is characterized cytogenetically by translocation t(X;18)(p11.2;q11.2). In this study, 28 cases that had been diagnosed initially as synovial sarcoma, including 2 fibrosarcomas, and 1 leiomyosarcoma were collected and examined for translocation t(X;18) on paraffin-embedded tissues by fluorescence in situ hybridization (FISH). Of the synovial sarcomas, 25 showed findings consistent with translocation t(X;18) with an additional copy signal for the total probe of X and 18 chromosomes. The other three cases, as well as the two fibrosarcomas and the leiomyosarcoma, did not show this translocation. One (case 26) of three negative cases was diagnosed finally as leiomyosarcoma and another (case 27) as malignant peripheral nerve sheath tumor from histological and immunohistochemical analysis. Thus, in all, 25 (96%) of 26 synovial sarcomas showed findings consistent with translocation t(X;18). In summary, translocation t(X;18) is a chromosomal aberration specific for synovial sarcoma. The fluorescence in situ hybridization technique can be used even on cells from paraffin-embedded tissues, and is a useful diagnostic aid for synovial sarcoma. Images Figure 1 Figure 2

Angular diameters of the carbon stars UU Aurigae, Y Canum Venaticorum, and TX PISCIUM from optical long-baseline interferometry  

NASA Astrophysics Data System (ADS)

The angular diameters of the three carbon stars UU Aur, Y CVn, and TX Psc have been determined with the MkIII Optical Interferometer. Measurements of UU Aur at ??= 712, 754, and 800nm agree well with each other; the weighted mean for the uniform disk diameter is ?_UD_ = 11.28 +/-0.21mas. For Y CVn, ?_UD_ = 13.81 +/-0.43mas is obtained at 800nm. There are indications of temporal variations of the diameter of TX Psc; values between 9.4 and 11.1mas were measured for this star. Effective temperatures are calculated for these three stars and for six other carbon stars for which diameters measured with the lunar occultation technique have been published. These fundamentally determined effective temperatures correlate well with, but are on average about 100K cooler than, effective temperatures for the same stars obtained with the infrared flux method by Tsuji (1981). Color temperatures determined by Baumert (1972) and by Gow (1977) correlate poorly with effective temperatures.

A Detailed Process Based Evaluation of Photochemical Air Quality Model Simulations of Houston, TX  

NASA Astrophysics Data System (ADS)

This work will present a process based evaluation of several modeling attempts of the Houston, TX non- attainment area. These modeling attempts include efforts by the Texas state agency, private consultants, and several Universities, resulting in multiple simulations of the same modeling episode and domain. These simulations were performed with the Comprehensive Air quality Model with extensions (CAMx) under a variety of meteorological and emission inputs. Through an initial comparison of model and ambient data the model underpredicts ozone concentrations in nearly every modeling attempt. This observation held true even when a large artificial imputation of ozone precursors, specifically ethylene and propylene, were added to some modeling simulations. An examination of the level of agreement between model predictions and observations of ozone concentrations, however, is not a sufficient method to understand the reasons for this inaccuracy. This is especially true in a non-linear feedback system such as ozone formation where the same ozone prediction can be reached through the combination of various physical and chemical processess. A more meaningful method of model analysis that focuses on theses processes lead to the development of the pyPA (Process Analysis in python) tool. This tool provides a framework for an in-depth analysis of modeling data by quantifying radical budgets, source and fate of ozone precursors, and the physical processes that effect each species. The pyPA tool was used to analyze each simulation scenario of the Houston airshed allowing for a process based intercomparison. An analysis of the radical budget revealed a deficient source of organically derived free radicals (HO2 and OH.) in the modeling system. Atmospheric reactivity and consequently ozone formation was limited by lack of radical sources; regardless of the levels of ethylene or propylene introduced into the system. NOx overpredictions by a factor of two further depleted the limited pool of radicals available for ozone chemistry. The pyPA tool was able to quantify the amount of OH. termination through the nitric acid reaction pathway. The photolysis of formaldehyde could be a possible source of missing radical species and the reason for suppressed ozone formation. This hypothesis is supported by ambient data revealing a deficiency by the model to predict sufficient levels of formaldehyde at ambient levels on the ground and aloft. Further testing of this hypothesis will be performed by introducing two possible sources of formaldehyde emissions that may have been omitted from the modeling inventory. The incomplete combustion of flares and mobile emissions will be tested as two possible sources of formaldehyde that are either underrepresented or omitted from the current inventory. This work will present the findings of our investigation of this formaldehyde imputation in terms of several key chemical parameters provided by the pyPA tool such as the cycling of OH. and NO, and a detailed mapping of the source and fate of radicals, ozone, and ozone precursors.

These surveys were designed to provide background information supporting Surface-to-Surface and Well-to-Well resistivity surveys of Waste Management Area TX-TY. The objective of the preliminary investigation was to collect background characterization information with GPR to understand the spatial distribution of metallic objects that could potentially interfere with the results from high resolution resistivity{trademark} surveys. The results of the background characterization confirm the existence of documented infrastructure, as well as highlight locations of possible additional undocumented subsurface metallic objects.

Relation of structure, magnetism, doping and pressure in AFe2-xTxAs2 (T=Co,Rh,Ru)  

NASA Astrophysics Data System (ADS)

We present an overview of our recent investigations on the SrFe2-xTxAs2 (T = Co, Ru, Rh) compounds. In our joint experimental and theoretical study, we report the influence of hydrostatic pressure and substitution at the Fe site on the magneto-structural and superconducting transitions. The magnetism is weakened upon the application of pressure as indicated by resistivity, X-ray data and density functional band structure calculations. Similar to substitution on the Sr site, substitutions on the Fe-site quench the magnetic transition and induce bulk superconductivity with Tc up to 20 K for ambient pressure and up to 27 K for underdoped SrFe2-xCoxAs2 for pressures of 2.6GPa. In our analysis, we attempt to disentangle the interplay of charge doping and structural changes induced by the substitution and by external pressure.

2004 Initial Assessments for the T and TX TY Tank Farm Field Investigation Report (FIR): Numerical Simulations  

SciTech Connect

In support of CH2M HILL Hanford Group, Inc.s (CHG) preparation of a Field Investigative Report (FIR) for the Hanford Site Single-Shell Tank Waste Management Area (WMA) T and TX-TY, a suite of numerical simulations of flow and solute transport was executed using the STOMP code to predict the performance of surface barriers for reducing long-term risks from potential groundwater contamination at the T and TX-TY WMA. The scope and parametric data for these simulations were defined by a modeling data package provided by CHG. This report documents the simulation involving 2-D cross sections through the T Tank and the TX-TY Tank Farm. Eight cases were carried out for the cross sections to simulate the effects of interim barrier, water line leak, inventory distribution, and surface recharge on water flow and the transport of long-lived radionuclides (i.e., technecium-99 and uranium) and chemicals (i.e., nitrate and chromium For simulations with barriers, it is assumed that an interim barrier is in place by the year 2010. It was also assumed that, for all simulations, as part of tank farm closure, a closure barrier was in place by the year 2040. The modeling considers the estimated inventories of contaminants within the vadose zone and calculates the associated risk. It assumes that no tanks will leak in the future. Initial conditions for contaminant concentration are provided as part of inventory estimates for uranium, technetium-99, nitrate, and chromium. For moisture flow modeling, Neumann boundary conditions are prescribed at the surface with the flux equal to the recharge rate estimate. For transport modeling, a zero flux boundary is prescribed at the surface for uranium, technetium-99, nitrate, and chromium. The western and eastern boundaries are assigned no-flux boundaries for both flow and transport. The water table boundary is prescribed by water table elevations and the unconfined aquifer hydraulic gradient. No-flux boundaries are used for the lower boundary. Numerical results were obtained for compliance at the WMA boundary, 200 Areas boundary, exclusion boundary beyond the 200 Areas, and the Columbia River (DOE-RL 2000). Streamtube/analytical models were used to route computed contaminant concentrations at the water table to the downstream compliance points. When the interim barrier was applied at 2010, the soil was desaturated gradually. The difference in saturation of the soil with and without the interim barrier was the largest at 2040, the time the closure barrier was applied. After this, the difference in saturation in the two cases became smaller with time. Generally, the solutes broke though faster if there was a water line leak. A relative small five-day leak (Case 4) had little effect on the peak concentration, while a large 20-yr leak (Case 3) increased the peak concentration significantly and reduced the solute travel in the vadose zone. The distribution of the inventory, either uniform or nonuniform, has little effect on peak arrival time; the peak concentrations of the conservative solutes varied by -6.9 to 0.2% for the T tank farm and by 11 to 49.4% for the TX tank farm. The reduction of the meteoric recharge before the barrier was applied led to less soil saturation, as expected, and thus longer solute travel time in the vadose zone and smaller peak fence line concentration. The effect on soil saturation lasted for about another 50 years after the barrier was applied at 2050. However, the reduced recharge rate affected the breakthough curve till the end of the simulation. The fence line concentrations at the year 3000 were always higher for cases with reduced natural recharge than for those of the base case, which indicates that the fundamental impact of the reduced natural recharge is a smoothing of the breakthrough concentrations at the compliance points.

Characterization of a Novel Bm?TX47 Toxin Modulating Sodium Channels: The Crucial Role of Expression Vectors in Toxin Pharmacological Activity  

PubMed Central

Long-chain scorpion toxins with four disulfide bridges exhibit various pharmacological features towards the different voltage-gated sodium channel subtypes. However, the toxin production still remains a huge challenge. Here, we reported the effects of different expression vectors on the pharmacological properties of a novel toxin Bm?TX47 from the scorpion Buthus martensii Karsch. The recombinant Bm?TX47 was obtained using the expression vector pET-14b and pET-28a, respectively. Pharmacological experiments showed that the recombinant Bm?TX47 was a new ?-scorpion toxin which could inhibit the fast inactivation of rNav1.2, mNav1.4 and hNav1.5 channels. Importantly, the different expression vectors were found to strongly affect Bm?TX47 pharmacological activities while toxins were obtained by the same expression and purification procedures. When 10 M recombinant Bm?TX47 from the pET-28a vector was applied, the values of I5ms/Ipeak for rNav1.2, mNav1.4 and hNav1.5 channels were 44.12% 3.17%, 25.40% 4.89% and 65.34% 3.86%, respectively, which were better than those values of 11.33% 1.46%, 15.96% 1.87% and 5.24% 2.38% for rNav1.2, mNav1.4 and hNav1.5 channels delayed by 10 M recombinant Bm?TX47 from the pET-14b vector. The dose-response experiments further indicated the EC50 values of recombinant Bm?TX47 from the pET-28a vector were 7262.9 755.9 nM for rNav1.2 channel and 1005.8 118.6 nM for hNav1.5 channel, respectively. Together, these findings highlighted the important role of expression vectors in scorpion toxin pharmacological properties, which would accelerate the understanding of the structure-function relationships of scorpion toxins and promote the potential application of toxins in the near future.

Commodity Flow Study - Clark County, Nevada, USA  

SciTech Connect

The United States Department of Energy has designated Clark County, Nevada as an 'Affected Unit of Local Government' due to the potential for impacts by activities associated with the Yucca Mountain High Level Nuclear Waste Repository project. Urban Transit, LLC has led a project team of transportation including experts from the University of Nevada Las Vegas Transportation Research Center to conduct a hazardous materials community flow study along Clark County's rail and truck corridors. In addition, a critical infrastructure analysis has also been carried out in order to assess the potential impacts of transportation within Clark County of high level nuclear waste and spent nuclear fuel to a proposed repository 90 miles away in an adjacent county on the critical infrastructure in Clark County. These studies were designed to obtain information relating to the transportation, identification and routing of hazardous materials through Clark County. Coordinating with the United States Department of Energy, the U.S. Department of Agriculture, the U. S. Federal Highway Administration, the Nevada Department of Transportation, and various other stakeholders, these studies and future research will examine the risk factors along the entire transportation corridor within Clark County and provide a context for understanding the additional vulnerability associated with shipping spent fuel through Clark County.

Environmental assessment: Deaf Smith County site, Texas  

SciTech Connect

In February 1983, the US Department of Energy (DOE) identified a location in Deaf Smith County, Texas, as one of nine potentially acceptable sites for a mined geologic repository for spent nuclear fuel and high-level radioactive waste. To determine their suitability, the Deaf Smith County site and the eight other potentially sites have been evaluated in accordance with the DOE's General Guidelines for the Recommendation of Sites for the Nuclear Waste Repositories. The Deaf Smith County site is in the Permian Basin, which is one of five distinct geohydrologic settings considered for the first repository. On the basis of the evaluations reported in this EA, the DOE has found that the Deaf Smith County site is not disqualified under the guidelines. On the basis of these findings, the DOE is nominating the Deaf Smith County site as one of the five sites suitable for characterization. 591 refs., 147 figs., 173 tabs.

Lea County 001, an H5 chondrite, and Lea County 002, an ungrouped type 3 chondrite  

NASA Astrophysics Data System (ADS)

A search of active deflation basins near Jal, Lea County, New Mexico resulted in the discovery of two meteorites, Lea County 001 and 002. Lea County 001 has mean olivine and low-Ca pyroxene compositions of Fa(19) and Fs(17), respectively. These and all other mineralogical and petrological data collected indicate a classification of H5 for this stone. Lea County 002 has mean olivine and low-Ca pyroxene compositions of Fa(2) and Fs(4), and is unequilibrated. Although it is mineralogically most similar to Kakangari and chondritic clasts within Cumberland Falls, the high modal amount of forsterite makes Lea County a unique type 3 chondrite. Oxygen isotope data for Lea County 002 fall on an 0-16-mixing line through those of the enstatite meteorites and IAB irons, a feature shared by Kakangari.

Linear DNA for Rapid Prototyping of Synthetic Biological Circuits in an Escherichia coli Based TX-TL Cell-Free System.  

PubMed

Accelerating the pace of synthetic biology experiments requires new approaches for rapid prototyping of circuits from individual DNA regulatory elements. However, current testing standards require days to weeks due to cloning and in vivo transformation. In this work, we first characterized methods to protect linear DNA strands from exonuclease degradation in an Escherichia coli based transcription-translation cell-free system (TX-TL), as well as mechanisms of degradation. This enabled the use of linear DNA PCR products in TX-TL. We then compared expression levels and binding dynamics of different promoters on linear DNA and plasmid DNA. We also demonstrated assembly technology to rapidly build circuits entirely in vitro from separate parts. Using this strategy, we prototyped a four component genetic switch in under 8 h entirely in vitro. Rapid in vitro assembly has future applications for prototyping multiple component circuits if combined with predictive computational models. PMID:24303785

Structural and Phylogenetic Studies with MjTX-I Reveal a Multi-Oligomeric Toxin - a Novel Feature in Lys49-PLA2s Protein Class  

PubMed Central

The mortality caused by snakebites is more damaging than many tropical diseases, such as dengue haemorrhagic fever, cholera, leishmaniasis, schistosomiasis and Chagas disease. For this reason, snakebite envenoming adversely affects health services of tropical and subtropical countries and is recognized as a neglected disease by the World Health Organization. One of the main components of snake venoms is the Lys49-phospholipases A2, which is catalytically inactive but possesses other toxic and pharmacological activities. Preliminary studies with MjTX-I from Bothrops moojeni snake venom revealed intriguing new structural and functional characteristics compared to other bothropic Lys49-PLA2s. We present in this article a comprehensive study with MjTX-I using several techniques, including crystallography, small angle X-ray scattering, analytical size-exclusion chromatography, dynamic light scattering, myographic studies, bioinformatics and molecular phylogenetic analyses.Based in all these experiments we demonstrated that MjTX-I is probably a unique Lys49-PLA2, which may adopt different oligomeric forms depending on the physical-chemical environment. Furthermore, we showed that its myotoxic activity is dramatically low compared to other Lys49-PLA2s, probably due to the novel oligomeric conformations and important mutations in the C-terminal region of the protein. The phylogenetic analysis also showed that this toxin is clearly distinct from other bothropic Lys49-PLA2s, in conformity with the peculiar oligomeric characteristics of MjTX-I and possible emergence of new functionalities inresponse to environmental changes and adaptation to new preys.

Purification, molecular cloning and functional characterization of HelaTx1 (Heterometrus laoticus): the first member of a new ?-KTX subfamily.  

PubMed

Given their medical importance, most attention has been paid toward the venom composition of scorpions of the Buthidae family. Nevertheless, research has shown that the venom of scorpions of other families is also a remarkable source of unique peptidyl toxins. The ?-KTx family of voltage-gated potassium channel (VGPC) scorpion toxins is hereof an example. From the telson of the scorpion Heterometrus laoticus (Scorpionidae), a peptide, HelaTx1, with unique primary sequence was purified through HPLC and sequenced by Edman degradation. Based on the amino acid sequence, the peptide could be cloned and the cDNA sequence revealed. HelaTx1 was chemically synthesized and functionally characterized on VGPCs of the Shaker-related, Shab-related, Shaw-related and Shal-related subfamilies. Furthermore, the toxin was also tested on small- and intermediate conductance Ca(2+)-activated K(+) channels. From the channels studied, K(v)1.1 and K(v)1.6 were found to be the most sensitive (K(v)1.1 EC(50)=9.91.6 ?M). The toxin did not alter the activation of the channels. Competition experiments with TEA showed that the toxin is a pore blocker. Mutational studies showed that the residues E353 and Y379 in the pore of K(v)1.1 act as major interaction points for binding of the toxin. Given the amino acid sequence, the predicted secondary structure and the biological activity on VGPCs, HelaTx1 should be included in the ?-KTX family. Based on a phylogenetic study, we rearranged this family of VGPC toxins into five subfamilies and suggest that HelaTx1 is the first member of the new ?-KTx5 subfamily. PMID:22305749

Dipeptidyl-peptidase-like-proteins confer high sensitivity to the scorpion toxin AmmTX3 to Kv4-mediated A-type K+ channels  

PubMed Central

K+ channels containing Kv4.2 and Kv4.3 pore-forming subunits mediate most of the subthreshold-operating somatodendritic A-type K+ current in CNS neurons. These channels are believed to be important in regulating the frequency of repetitive firing, the backpropagation of action potential into dendrites, and dendritic integration and plasticity. Moreover, they have been implicated in several diseases from pain to epilepsy and autism spectrum disorders. The lack of toxins that specifically and efficiently block these channels has hampered studies aimed at confirming their functional role and their involvement in disease. AmmTX3 and other related members of the ?-KTX15 family of scorpion toxins have been shown to block the A-type K+ current in cultured neurons, but their specificity has been questioned because the toxins do not efficiently block the currents mediated by Kv4.2 or Kv4.3 subunits expressed in heterologous cells. Here we show that the high-affinity blockade of Kv4.2 and Kv4.3 channels by AmmTX3 depends on the presence of the auxiliary subunits DPP6 and DPP10. These proteins are thought to be components of the Kv4 channel complex in neurons and to be important for channel expression in dendrites. These studies validate the use of AmmTX3 as a blocker of the Kv4-mediated A-type K+ current in neurons.

t(X;14)(p11.4;q32.33) is recurrent in marginal zone lymphoma and up-regulates GPR34.  

PubMed

Genetic events underlying pathogenesis of nodal and extranodal marginal zone lymphoma are not completely understood. We report here a novel t(X;14)(p11.4;q32.33) identified in 4 lymphoma cases: 2 with a mucosa-associated lymphoid tissue lymphoma, one with a nodal marginal zone lymphoma and one with gastric diffuse large B-cell lymphoma. In all cases, lymphoma evolved from a previous auto-immune disorder. Fluorescence in situ hybridization and molecular studies showed that t(X;14), which is mediated by immunoglobulin heavy chain locus, targets the GPR34 gene at Xp11.4. Upregulation of GPR34 mRNA and aberrant expression of GPR34 protein has been demonstrated in 3 presented cases by quantitative real-time polymerase chain reaction and immunohistochemistry, respectively. GPR34 belongs to the largest family of cell surface molecules involved in signal transmission that play important roles in many physiological and pathological processes, including tumorigenesis. Although functional consequences of t(X;14) have not been identified, our studies suggest that up-regulated GPR34 activate neither nuclear factor-?B nor ELK-related tyrosine kinase. PMID:22058210

Impact of Sea Level Rise on the Attenuation of Hurricane Storm Surge by Wetlands in Corpus Christi, TX  

NASA Astrophysics Data System (ADS)

Celso Ferreira1, Jennifer L. Irish2, Francisco Olivera3 1 Graduate Research Assistant, Department of Civil Engineering, Texas A&M University, College Station, TX 77843, email: celsoferreira@tamu.edu. 2 Associate Professor, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA 24061, email: jirish@vt.edu 3 Associate Professor, Department of Civil Engineering, Texas A&M University, College Station, TX 77843, email: folivera@civil.tamu.edu. Texas has historically faced severe hurricanes with Ike being the most recent major storm example. It is believed that coastal wetlands might reduce the impact of the storm surge on coastal areas, acting as a natural protection against hurricane flooding, especially for small hurricanes and tropical storms. Considering the expected rise in the mean sea level, wetland composition and spatial distribution are also expected to change as the environmental conditions change along the coast. We analyzed a range of Intergovernmental Panel on Climate Change (IPCC) projections for sea level rise (SLR) to simulate wetland alterations and evaluate their impact on hurricane storm surge. The analyses was conducted for Corpus Christi Bay using a pre-validated, physically based, hydrodynamic model (ADCIRC) and a wind and pressure field model (PBL) representing the physical properties of historical hurricane Bret. The calculations were performed using an unstructured numerical grid with 3.3 million nodes covering part of the Atlantic Ocean and the entire Gulf of Mexico (resolution from 2000 km to 50 meters at the coast). Wetlands are represented in the numerical model through their influence on the frictional resistance proprieties and bathymetric changes. To characterize the wetland types and their spatial distribution along the coast, we used six different land use databases from the National Land Cover Dataset (NLCD) (1992, 2001), the National Wetlands Inventory (NWI) (1993) and the Coastal Change Analysis Program (C-CAP) (1996, 2001, 2006). The wetland degradation by SLR was spatially simulated using empirical relations for water levels/tides and ecosystem resilience. The choice of wetland database resulted in surge variations of less than 0.1 m in locations inside Corpus Bay. Preliminary studies considering IPCC scenarios (B1, A1F1, B1FI) for 2030 and 2080 plus predicted local subsidence showed that, although the SLR scenarios for 2030 did not affect surge considerably inside the bay (SLR increase removed after simulation), the greater degradation of the wetlands caused by SLR on the 2080 scenarios (0.80 m SLR + subsidence) resulted in surges on the order of 0.3 m higher for Hurricane Bret in selected locations. Future work includes performing analyses using different storm conditions (forward speed, central pressure and storm radius), additional and less conservative SLR scenarios, damage assessment and also include the effects of waves using the coupled version of ADCIRC with UNSWAN.

Lanthanum and lanthanides in atmospheric fine particles and their apportionment to refinery and petrochemical operations in Houston, TX  

NASA Astrophysics Data System (ADS)

A study was conducted in Houston, TX focusing on rare earth elements (REEs) in atmospheric fine particles and their sources. PM 2.5 samples were collected from an ambient air quality monitoring site (HRM3) located in the proximity of a large number of oil refineries and petrochemical industries to estimate the potential contributions of emissions from fluidized-bed catalytic cracking operations to ambient fine particulate matter. The elemental composition of ambient PM 2.5, several commercially available zeolite catalysts, and local soil was measured after microwave assisted acid digestion using inductively coupled plasmamass spectrometry. Source identification and apportionment was performed by principal component factor analysis (PCFA) in combination with multiple linear regression. REE relative abundance sequence, ratios of La to light REEs (Ce, Pr, Nd, and Sm), and enrichment factor analysis indicated that refining and petrochemical cat cracking operations were predominantly responsible for REE enrichment in ambient fine particles. PCFA yielded five physically meaningful PM 2.5 sources: cat cracking operations, a source predominantly comprised of crustal material, industrial high temperature operations, oil combustion, and sea spray. These five sources accounted for 82% of the total mass of atmospheric fine particles (less carbon and sulfate). Factor analysis confirmed that emissions from cat cracking operations primarily contributed to REE enrichment in PM 2.5 even though they comprised only 2.0% of the apportioned mass. Results from this study demonstrate the need to characterize catalysts employed in the vicinity of the sampling stations to accurately determine local sources of atmospheric REEs.

Impacts of cool cities on air quality: A preliminary modeling assessment for Nashville TN, Dallas TX and Atlanta GA  

SciTech Connect

Previous atmospheric modeling efforts that concentrated on the Los Angeles Basin suggested beneficial and significant air quality impacts from cool cities strategies. This paper discusses an extension of similar modeling efforts to three regions, Atlanta GA, Dallas - Ft. Worth TX, and Nashville TN, that experience smog and air quality problems. According to the older ozone air quality standard (120 ppb), these regions were classified as serious, moderate, and marginal, respectively, but may be out of compliance with respect to the newer, 80-ppb/8-hours standard. Results from this exploratory modeling work suggest a range of possible impacts on meteorological and air quality conditions. For example, peak ozone concentrations during each region's respective episode could be decreased by 1-6 ppb (conservative and optimistic scenarios, respectively) in Nashville, 5-15 ppb in Dallas - Fort Worth, and 5-12 ppb in Atlanta following implementation of cool cities. The reductions are generally smaller than those obtained from simulating the Los Angeles Basin but are still significant. In all regions, the simulations suggest, the net, domain-wide effects of cool cities are reductions in ozone mass and improvements in air quality. In Atlanta, Nashville, and Dallas, urban areas benefiting from reduced smog reach up to 8460, 7350, and 12870 km{sup 2} in area, respectively. Results presented in this paper should be taken as exploratory and preliminary. These will most likely change during a more comprehensive modeling study to be started soon with the support of the US Environmental Protection Agency. The main purpose of the present project was to obtain the initial data (emission inventories) for these regions, simulate meteorological conditions, and perform preliminary sensitivity analysis. In the future, additional regions will be simulated to assess the potential of cool cities in improving urban air quality.

Characteristic sequence motifs located at the genomic breakpoints of the translocation t(X;18) in synovial sarcomas.  

PubMed

The SYT-SSXI and SYT-SSX2 fusion genes, derived by reciprocal translocations t(X;18), are acquired genetic events strongly associated with the tumorigenesis of synovial sarcoma. In approaching the mechanisms underlying the formation of these fusion oncogenes, we have analysed the genomic sequences surrounding the SYT-SSX breakpoints in 10 tumors, two expressing SYT-SSXI and eight expressing SYT-SSX2 fusion transcripts. The breakpoints were found to be clustered in the 5' end of intron 10 of SYT, and in two cluster regions within intron 4 of SSX2, whereas the two breakpoints in SSX1 intron 4 were 0.5 kb apart. SYT intron 10 is abundant in repetitive regions with the interspersed repeats occupying 66% of the whole intron. Nine of the 10 breakpoints in intron 10 of SYT and six of the eight breakpoints in intron 4 of SSX2 were at or near repetitive regions. These findings suggest that repetitive regions may contribute to the distribution of genomic breakpoints. Several of the fusion sequences exhibited characteristic signs of nonhomologous end joining, including microhomologies at the end points as well as deletions. Sequences highly homologous (83-94%) to consensus topoisomerase II cleavage sites were identified at or near the breakpoints in all 10 tumors, suggesting a role of this enzyme in creating staggered ends at the breakpoint. Furthermore, sequences highly homologous to consensus Translin binding sequences were found at the breakpoints in two cases, and an Alu-Alu fusion and an insertion of a 206-bp LINE-1 element were found at the breakpoint in one case each. The demonstration of characteristic sequences at the SYT-SSX breakpoint regions is expected to improve our understanding of the molecular genetic mechanisms behind translocations in general, and of the SYT-SSX fusions in synovial sarcoma in particular.

Day Fire in Ventura County  

NASA Technical Reports Server (NTRS)

[figure removed for brevity, see original site] Annotated Version

The Day fire has been burning in Ventura County in Southern California since Labor Day, and has consumed more than 160,000 acres. As of September 29, it was 63 percent contained. The Advanced Spaceborne Thermal Emission and Reflection Radiometer on NASA's Terra satellite flew over the fire at 10 p.m. Pacific Time on September 28, and imaged the fire with its infrared camera. The hottest areas of active burning appear as red spots on the image. The blue-green background is a daytime image acquired in June, used as a background to allow firefighters to localize the hot spots.

With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission directorate.

Erie County residential energy-assistance program  

SciTech Connect

The Residential Energy Assistance Program (REAP) developed and demonstrated a method for coordinating City, County, and utility weatherization and support services so as to increase low and low-moderate income family participation in energy conservation activities within Erie County. A principal objective was to inprove participation of such families in New York State's Home Insulation and Energy Conservation Act (1977) energy audit and loan program. Coordination of weatherization and energy assistance services was carried out through the development of a reference guide containing the qualifications for each of the available programs. This Guide was used in conjunction with training for municipal and community agency housing staff and consumer education workshops to form the basis of a coordinated approach to promoting energy conservation in the low-income sector. Achieving active participation by the low-income sector in conservation awareness programs was difficult. A total of fourteen workshops were conducted throughout the County which were attended by 175 participants.

Just south of the Newark-New York City metropolitan area, urban meets rural in the fastest growing region of New Jersey. The two-year Monmouth/Ocean/Middlesex counties transit study brought to a focus an extensive 12-year history of efforts to improve transportation in this region of growing towns and long-distance commuters. The project, presented in this article, screened and evaluated some 40 potential rail and bus alternatives along eight corridors. As a result, two projects were recommended to progress further toward implementation: bus priority treatments as part of a potential $175 million widening of US 9, and passenger rail service (budgeted at $120 million) along a reconstructed former freight line through the center of Monmouth County and into Ocean County.

Dutchess County Resource Recovery Task Force report: Dutchess County Pyrolysis Program  

SciTech Connect

Dutchess County initiated development of a long-range master plan for Solid Waste Management in 1971. The plan included development of a resource recovery facility to service the municipalities in the County population center. Based on early recommendations, a pyrolysis facility employing Purox technology was to be implemented. A feasibility study, paid for by County funds was completed in 1975. The study provided siting recommendations, estimation of available waste, and preliminary facility design. Because of various considerations, the project was not developed. Under the Department of Energy grant, the County reassessed the feasibility of a resource recovery facility, with emphasis on confirming previous conclusions supporting the Purox technology, waste availability, energy recovery and sale and siting of the plant. The conclusions reached in the new study were: a resource recovery facility is feasible for the County; sufficient waste for such a facility is available and subject to control; While Purox technology was feasible it is not the most appropriate available technoloy for the County; that mass burning with steam recovery is the most appropriate technology; and that resource recovery while presently more expensive than landfilling, represents the only cost effective, energy efficient, and environmentally sound way to handle the solid waste problem in the County.

Energy Efficient Buildings, Salt Lake County, Utah  

SciTech Connect

Executive Summary Salt Lake County's Solar Photovoltaic Project - an unprecedented public/private partnership Salt Lake County is pleased to announce the completion of its unprecedented solar photovoltaic (PV) installation on the Calvin R. Rampton Salt Palace Convention Center. This 1.65 MW installation will be one the largest solar roof top installations in the country and will more than double the current installed solar capacity in the state of Utah. Construction is complete and the system will be operational in May 2012. The County has accomplished this project using a Power Purchase Agreement (PPA) financing model. In a PPA model a third-party solar developer will finance, develop, own, operate, and maintain the solar array. Salt Lake County will lease its roof, and purchase the power from this third-party under a long-term Power Purchase Agreement contract. In fact, this will be one of the first projects in the state of Utah to take advantage of the recent (March 2010) legislation which makes PPA models possible for projects of this type. In addition to utilizing a PPA, this solar project will employ public and private capital, Energy Efficiency and Conservation Block Grants (EECBG), and public/private subsidized bonds that are able to work together efficiently because of the recent stimulus bill. The project also makes use of recent changes to federal tax rules, and the recent re-awakening of private capital markets that make a significant public-private partnership possible. This is an extremely innovative project, and will mark the first time that all of these incentives (EECBG grants, Qualified Energy Conservation Bonds, New Markets tax credits, investment tax credits, public and private funds) have been packaged into one project. All of Salt Lake County's research documents and studies, agreements, and technical information is available to the public. In addition, the County has already shared a variety of information with the public through webinars, site tours, presentations, and written correspondence.

Geologic Map of Loudoun County, Virginia  

USGS Publications Warehouse

Introduction The geology of Loudoun County, Va., was mapped from 1988 through 1991 under a cooperative agreement between the U.S. Geological Survey (USGS) and the Loudoun County Office of Mapping and Geographic Information. This geologic map was compiled in 1993 from a series of detailed published and unpublished field investigations at scales of 1:12,000 and 1:24,000. Some of these same data were compiled as a digital geologic map at 1:100,000 scale (Burton and others, 1992a) and were the basis for a cost-benefit analysis of the societal value of geologic maps (Bernknopf and others, 1993).

Water-soluble colloidal manganese dioxide as an oxidant for L-tyrosine in the absence and presence of non-ionic surfactant TX-100.  

PubMed

Water-soluble colloidal manganese dioxide has been used to oxidize L-tyrosine in aqueous-acidic medium. The kinetics of the reaction was studied in the absence and presence of non-ionic surfactant (TX-100) using a spectrophotometric technique. As the reaction was fast under pseudo-first-order conditions ([L-tyrosine]>[MnO(2)]), the rate constants as a function of [L-tyrosine], [MnO(2)], [HClO(4)] and temperature were obtained under second-order conditions. The rate of the reaction increased and decreased with the increase in [L-tyrosine] and [MnO(2)], respectively. Perchloric acid, sodium pyrophosphate and sodium fluoride showed catalytic effect. The effect of externally added manganese(II) sulphate is complex. It is not possible to predict the exact dependence of the rate constants on manganese(II) concentration, which has a series of reactions with other reactants. The reaction is inhibited by the non-ionic surfactant TX-100. Activation parameters have been evaluated using Arrhenius and Eyring equations. Based on observed kinetic results, a probable mechanism for the reaction has been proposed which corresponds to fast adsorption of the reductant and hydrogen ion on the surface of colloidal MnO(2) followed by one-step two-electron transfer rate limiting process.

Characterization of Vadose Zone Sediments Below the TX Tank Farm: Boreholes C3830, C3831, C3832 and RCRA Borehole 299-W10-27  

SciTech Connect

This report was revised in September 2008 to remove acid-extractable sodium data from Tables 4.8, 4.28,4.43, and 4.59. The sodium data was removed due to potential contamination introduced during the acid extraction process. The rest of the text remains unchanged from the original report issued in April 2004. The overall goal of the Tank Farm Vadose Zone Project, led by CH2M HILL Hanford Group, Inc., is to define risks from past and future single-shell tank farm activities at Hanford. To meet this goal, CH2M HILL Hanford Group, Inc. tasked scientists from Pacific Northwest National Laboratory to perform detailed analyses on vadose zone sediments from within Waste Management Area (WMA) T-TX-TY. This report is the first of two reports written to present the results of these analyses. Specifically, this report contains all the geologic, geochemical, and selected physical characterization data collected on vadose zone sediment recovered from boreholes C3830, C3831, and C3832 in the TX Tank Farm, and from borehole 299-W-10-27 installed northeast of the TY Tank Farm.

The Tarantula Toxins ProTx-II and Huwentoxin-IV Differentially Interact with Human Nav1.7 Voltage Sensors to Inhibit Channel Activation and InactivationS?  

PubMed Central

The voltage-gated sodium channel Nav1.7 plays a crucial role in pain, and drugs that inhibit hNav1.7 may have tremendous therapeutic potential. ProTx-II and huwentoxin-IV (HWTX-IV), cystine knot peptides from tarantula venoms, preferentially block hNav1.7. Understanding the interactions of these toxins with sodium channels could aid the development of novel pain therapeutics. Whereas both ProTx-II and HWTX-IV have been proposed to preferentially block hNav1.7 activation by trapping the domain II voltage-sensor in the resting configuration, we show that specific residues in the voltage-sensor paddle of domain II play substantially different roles in determining the affinities of these toxins to hNav1.7. The mutation E818C increases ProTx-II's and HWTX-IV's IC50 for block of hNav1.7 currents by 4- and 400-fold, respectively. In contrast, the mutation F813G decreases ProTx-II affinity by 9-fold but has no effect on HWTX-IV affinity. It is noteworthy that we also show that ProTx-II, but not HWTX-IV, preferentially interacts with hNav1.7 to impede fast inactivation by trapping the domain IV voltage-sensor in the resting configuration. Mutations E1589Q and T1590K in domain IV each decreased ProTx-II's IC50 for impairment of fast inactivation by ?6-fold. In contrast mutations D1586A and F1592A in domain-IV increased ProTx-II's IC50 for impairment of fast inactivation by ?4-fold. Our results show that whereas ProTx-II and HWTX-IV binding determinants on domain-II may overlap, domain II plays a much more crucial role for HWTX-IV, and contrary to what has been proposed to be a guiding principle of sodium channel pharmacology, molecules do not have to exclusively target the domain IV voltage-sensor to influence sodium channel inactivation.
