Needs assessment for the Greenway Grand Forks-East Grand Forks development and public education  

NASA Astrophysics Data System (ADS)

Following the flood of 1997, the U.S. Army Corps of Engineers included the Greenway Grand Forks---East Grand Forks (the Greenway) as a flood control measure for Grand Forks, North Dakota and East Grand Forks, Minnesota. It extends along both the Red River of the North and the Red Lake River, encompassing 2200 acres of land. The cities of Grand Forks and East Grand Forks hired consultants to assist with the postflood planning process. The planning process culminated with the Red River of the North Greenway Final Report (Flink, 1998). The purpose of this study was to determine if the development of the Greenway addressed the objectives of the planning report. The history of the land adjacent to the rivers was reviewed to document the progression of riverfront development. Anecdotal evidence was collected, field observations were made, city council minutes were reviewed, Greenway Technical Committee members were interviewed, Greenway Technical Committee minutes were reviewed, and the Greenway Grand Forks---East Grand Forks survey results were reviewed to determine if the objectives of the Red River of the North Greenway Final Report were addressed. A cross section survey was designed by Laura Munski for this dissertation research. The survey was approved by the Greenway Technical Committee. The survey collected both quantitative and qualitative data from the community. The purpose of the survey portion of the research project was to ascertain how residents were kept informed of activities on the Greenway and what amenities residents were using on the Greenway and to solicit their comments regarding the Greenway. The results of the survey research were used in both marketing and event planning for the Greenway. The singular qualitative survey question gave respondents an opportunity to share their comments regarding the Greenway. The qualitative data analysis provided insight to the amenities and educational programs desired by respondents, their concerns regarding the Greenway, and the limitations of public knowledge regarding the Greenway. The Red River of the North Greenway Final Report (Flink, 1998) stated that the Greenway could be an excellent resource for supplementing educational curriculums. Greenways provide outdoor classrooms for both formal and informal education. The educational opportunities of other North American greenways were investigated and compared to the educational opportunities of the Greenway.

Flood of July 5-7, 1978, on the South Fork Zumbro River at Rochester, Minnesota  

USGS Publications Warehouse

The intense thunderstorm of July 5-6, 1978, caused record flooding on the South Fork Zumbro River at Rochester, Minnesota. The peak discharge on July 6 was 30,500 cubic feet per second compared with 19,600 cubic feet per second for the flood of March 1965, which was the largest previously known. The 1965 flood had a recurrence interval of about 30 years, whereas the 1978 flood had a recurrence interval exceeding 100 years. The flood waters claimed at least 5 lives and 5,000 people were forced to leave their homes. Millions of dollars in flood damage was reported, and this report summarizes some of the flood data and a photomosaic map shows the inundated area. (Kosco-USGS)

Water resources of the Grand Portage Indian Reservation, northeastern Minnesota  

USGS Publications Warehouse

Proterozoic bedrock aquifers are the principal source of water supply in the Grand Portage Indian Reservation. The bedrock aquifers are the (1) North Shore Volcanic Group; (2) Keweenawan Volcanic and intrusive rocks and (3) Rove Formation. Sand and gravel aquifers are a small source of water. The median estimate of transmissivity determined from data for 17 wells completed in bedrock was 17 feet squared per day; the range was from 3 to 500 feet squared per day. Estimated transmissivity did not show a clear trend in variation with depth of bed- rock penetrated by the well borehole. Reported yield of 19 wells completed in bedrock had a range of 1 to 100 gallons per minute and a median of 7 gallons per minute. Hydrofracturing of two wells completed in bedrock increased their yield from about 0.25 and 0.05 gallons per minute before hydrofracturing, to about 1.2 and 1.5 gallon per minute, respectively, after hydrofracturing. Although the estimated yield from the two wells was increased by nearly 5 and by 30 times from hydrofracturing, the well yield after hydro- fracturing was still small. Water types determined from analyses of water from nine wells completed in bedrock were sodium-chloride, calcium-chloride, sodium-bicarbonate, and calcium-bicarbonate. Water from three wells had concentrations of dissolved solids and dissolved chloride that were higher than their respective SMCLs (Secondary Maximum Con- taminant Levels) established by the USEPA (U.S. Environmental Protection Agency). Concentrations of dissolved arsenic, barium, chromium, copper, silver, zinc, and selenium in water from the nine wells were less than their respective USEPA MCLs (Maximum Contaminant Levels) and USEPA SMCLs. The concentration of dissolved lead in water from the nine wells was less than the detection limit of 100 ug/L (micrograms per liter). Water from an observation well located about 200 feet from an abandoned landfill and screened from 79 to 84 feet below land surface in a gravel aquifer had a trace amount of toluene (0.2 ug/L). The presence of toluene suggested possible contamination.

Groundwater and climate change: a sensitivity analysis for the Grand Forks aquifer, southern British Columbia, Canada  

NASA Astrophysics Data System (ADS)

The Grand Forks aquifer, located in south-central British Columbia, Canada was used as a case study area for modeling the sensitivity of an aquifer to changes in recharge and river stage consistent with projected climate-change scenarios for the region. Results suggest that variations in recharge to the aquifer under the different climate-change scenarios, modeled under steady-state conditions, have a much smaller impact on the groundwater system than changes in river-stage elevation of the Kettle and Granby Rivers, which flow through the valley. All simulations showed relatively small changes in the overall configuration of the water table and general direction of groundwater flow. High-recharge and low-recharge simulations resulted in approximately a +0.05 m increase and a -0.025 m decrease, respectively, in water-table elevations throughout the aquifer. Simulated changes in river-stage elevation, to reflect higher-than-peak-flow levels (by 20 and 50%), resulted in average changes in the water-table elevation of 2.72 and 3.45 m, respectively. Simulated changes in river-stage elevation, to reflect lower-than-baseflow levels (by 20 and 50%), resulted in average changes in the water-table elevation of -0.48 and -2.10 m, respectively. Current observed water-table elevations in the valley are consistent with an average river-stage elevation (between current baseflow and peak-flow stages). L'aquifère de Grand Forks, situé en Colombie britannique (Canada), a été utilisé comme zone d'étude pour modéliser la sensibilité d'un aquifère à des modifications de la recharge et du niveau de la rivière, correspondant à des scénarios envisagés de changement climatique dans cette région. Les résultats font apparaître que les variations de recharge de l'aquifère pour différents scénarios de changement climatique, modélisées pour des conditions de régime permanent, ont un impact sur le système aquifère beaucoup plus faible que les changements du niveau des rivières Kettle et Granby, qui coulent dans la vallée. Toutes les simulations ont montré des différences relativement faibles dans la configuration d'ensemble de la nappe et dans la direction générale des écoulements. Des simulations de conditions de recharge forte et de recharge faible produisent respectivement une remontée de 0,05 m et un abaissement de 0,025 m, approximativement, des cotes de la nappe pour l'ensemble de l'aquifère. Des changements simulés de la cote du niveau de la rivière, pour refléter des niveaux plus hauts que ceux des pics de crues (de 20 et de 50%), produisent respectivement des remontées de la nappe de 2,72 et 3,45 m en moyenne. Des changements simulés de l'altitude du niveau de la rivière, pour refléter des niveaux plus bas que ceux de basses eaux (de 20 et de 50%), produisent respectivement des abaissements de la nappe de 0,48 et 2,10 m en moyenne. Les altitudes courantes observées de la nappe dans la vallée sont cohérentes avec une cote moyenne du niveau de la rivière (entre les niveaux courants de basses eaux et de crues). El acuífero de los Grand Forks, situado al sur de la Columbia Británica central (Canadá) ha sido utilizado como lugar de estudio para modelar la sensibilidad de un acuífero a los cambios en la recarga y el caudal de los ríos de acuerdo con escenarios previstos de cambio climático en la región. Los resultados sugieren que las variaciones en la recarga al acuífero bajo los diversos escenarios, que han sido modelados en régimen estacionario, tienen un impacto mucho menor en las aguas subterráneas que los cambios en el caudal de los ríos Kettle y Granby, que discurren por el valle. Todas las simulaciones muestran diferencias relativamente pequeñas en la configuración regional de los niveles freáticos y en la dirección general del flujo subterráneo. Las simulaciones de recarga elevada y baja causan un incremento de 0,05 m y un decremento de 0,025 m, respectivamente, en los niveles del acuífero.

Hydrology and Water Quality of the Grand Portage Reservation, Northeastern Minnesota, 1991-2000  

USGS Publications Warehouse

The Grand Portage Reservation is located in northeastern Cook County, Minnesota at the boundary between Minnesota, USA, and Ontario, Canada. Between 1991 and 2000 the U.S. Geological Survey conducted a series of studies, with the cooperation with Grand Portage Band of Chippewa, to describe the water resources of the Grand Portage Reservation. Ground water moves primarily through fractures in the bedrock, probably in three ground-water systems: local, regional, and deep. Lake Superior is thought to be the discharge point for brines in the deep ground-water flow system. The watersheds in the Grand Portage Reservation are small and steep; consequently streams in the Grand Portage Reservation tend to be flashy. Lake stages rise and fall with rainfall. The pH of water in the Reservation is generally alkaline (pH greater than 7.0). The alkalinity of water in the Reservation is low. Concentrations of major ions are much greater in ground water than in spring water and surface water. The ionic composition of water in the Reservation differs depending upon the source of the water. Water from 11 of the 20 wells sampled are a calcium-sodium-chloride type. Water from wells GW-2, GW-7, and GW-11 had much greater specific conductance concentrations of major ions compared to the other wells. Some spring water (SP-1, SP-3, SP-4, SP-6,and SP-8) is calcium-bicarbonate type like surface water, whereas other spring water (SP-5 and SP-7) is similar to the cal-cium-sodium-chloride type occurring in samples from about one-half the wells. The major chemical constituents in surface water are bicarbonate, calcium, and magnesium. Measured tritium and sulfur hexafluoride (SF6) concentrations in water samples from springs and wells were used todetermine the recharge age of the sampled water. The recharge ages of two of the wells sampled for tritium are before 1953. The recharge ages of the remaining 10 samples for tritium are probably after 1970. The recharge ages of seven SF6 samples were between 1973 and 1998.

Water-Quality Data from Lakes and Streams in the Grand Portage Reservation, Minnesota, 1997-98  

USGS Publications Warehouse

The Grand Portage Reservation is located in northeastern Cook County, Minnesota (fig. 1). In 1997 and 1998 the U.S. Geological Survey (USGS) conducted a study, in cooperation with the Grand Portage Band of Chippewa, to determine the quality of water in selected inland lakes and streams in the Reservation. The USGS collected and analyzed water from two streams, two wetlands, and four lakes (fig 1). Water samples were collected in the spring and fall of 1997 and 1998. In addition, samples of bottom sediments were collected from two of the four lakes in 1998. The purpose of this report is to present the data collected by the USGS from the study during 1997-98. Water-quality data include temperature, pH, specific conductance, dissolved oxygen, alkalinity, and concentrations of major ions, nutrients, and trace metals. Lake sediment data include concentrations of trace metals and selected organic compounds.

Linking Climate, Hydrology and Groundwater in High-Resolution Transient Groundwater Flow Models: a Case Study For a Climate Change Impacts Assessment in Grand Forks, BC  

NASA Astrophysics Data System (ADS)

A case study of an unconfined aquifer in the Grand Forks valley in south-central BC was used to develop methodology for linking climate models, hydrologic models, and groundwater models to investigate future impacts of climate change on groundwater resources. A three dimensional groundwater flow model of variable spatial resolution (constrained by borehole spacing) was implemented in MODFLOW, and calibrated to observation well data. Multiple scenarios of the hydraulic conductivity fields were used in a sensitivity analysis. A new methodology was developed for generating spatially-distributed and temporally-varying recharge zonation for the surficial aquifer, using GIS linked to the one-dimensional HELP (USEPA) hydrologic model that estimates aquifer recharge. The recharge model accounts for soil distribution, vadose zone depth and hydraulic conductivity, extent of impermeable areas, surficial geology, and vadose zone thickness. Production well pumping and irrigation return flow during the summer season were included in recharge computations. Although recharge was computed as monthly averages per climate scenario, it is driven by physically-based daily weather inputs generated by a stochastic weather generator and calibrated to local observed climate. Four year long climate scenarios were run, each representing one typical year in the present and future (2020s, 2050s, and 2080s), by perturbing the historical weather according to the downscaled CGCM1 general circulation model results (Environment Canada). CGCM1 model outputs were calibrated for local conditions during the downscaling procedure. These include absolute and relative changes in precipitation; including indirect measures of precipitation intensity, dry and wet spell lengths, temperature, and solar radiation for the evapotranspiration model. CGCM1 downscaling was also used to predict basin-scale runoff for the Kettle River upstream of Grand Forks. This river exerts strong control on the groundwater levels in the aquifer and physically-based discharge predictions were used in the transient groundwater flow model. Modeled discharge hydrographs were converted to river stage hydrographs at each of 123 river segments, and interpolated between known river channel cross-sections. Stage-discharge curves were estimated using the BRANCH model and calibrated to observed historical data. River channels were represented in three-dimensions using a high grid density (14 to 25 m) in MODFLOW, which were mapped onto river segments. River stage schedules along the 26 km long meandering channel were imported at varying, but high, temporal resolution (1 to 5 days) for every cell location independently. Head differences were computed at each time step for historical and future, mapped in GIS and linked to the MODFLOW model. Temporal changes in mass balance components show relations between pumping, storage, recharge, and flow. Within an annual cycle and between climate scenarios the results show different spatial and temporal distributions in groundwater conditions. Groundwater levels near the river floodplain are predicted to be lower earlier in the year under future climate scenarios, but away from rivers, groundwater levels increase slightly due to the predicted increase in recharge.

U–Pb geochronological constraints on the timing of episodic regional metamorphism and rapid high-T exhumation of the Grand Forks complex, British Columbia  

NASA Astrophysics Data System (ADS)

The Grand Forks complex (GFC) is a fault-bounded metamorphic core complex in the southern Omineca Belt of British Columbia, Canada. It experienced prograde metamorphism ranging from upper-amphibolite to granulite facies conditions during the Mesozoic to early Tertiary compressional stage of the Cordilleran orogeny. Peak metamorphism was followed by multi-stage exhumation in the Early Eocene. This study provides U–Pb monazite and zircon constraints on the timing of metamorphic episodes in the GFC and subsequent high-T, amphibolite facies decompression in the Early Eocene. Monazite LA-ICP-MS ages from metapelitic gneisses record episodic metamorphism from the Late Jurassic to Paleocene, with peak metamorphism occurring between ~ 59 and 50 Ma. Peak metamorphism was followed by rapid, near-isothermal decompression of the GFC between ~ 52 and 50 Ma, and leucosome crystallization at ~ 50 Ma. Thermodynamic modeling of metapelites in the system MnNCKFMASHPYCe predicts that monazite was not stable at peak metamorphic conditions, consistent with the dominant population of ~ 59 Ma ages representing growth along the prograde path, most likely at subsolidus conditions. Growth of widespread high-Y monazite rims (~ 50 Ma) is predicted along suprasolidus decompression and cooling paths. Zircon SHRIMP ages from igneous bodies in the GFC and hanging wall of the bounding Kettle River fault (KRF) suggest ductile deformation related to high-T decompression of the GFC was ongoing at 51 Ma but had ceased by 50 Ma, truncated by post-kinematic granitoids. This high-T deformation predates subsequent greenschist facies extension on the overlying KRF. A pre-KRF, hanging wall ductile shear zone is constrained to ~ 59–51 Ma. It deforms 59 Ma Ladybird suite leucogranites and may be related to high-T exhumation of the core complex. Rapid, > 100 °C/Ma cooling rates are required to accommodate high-T (amphibolite facies) exhumation of the GFC at 52–50 Ma followed by low-T (greenschist facies) exhumation at ~ 49 Ma.

Ground-water/surface-water interaction in nearshore areas of Three Lakes on the Grand Portage Reservation, northeastern Minnesota, 2003-04  

USGS Publications Warehouse

The U.S. Geological Survey (USGS), in cooperation with the Grand Portage Band of Chippewa Indians, applied three techniques to assess ground-water/surface-water interaction in nearshore areas of three lakes (North, Teal, and Taylor) on the Grand Portage Reservation in northeastern Minnesota. At each lake, analyses of existing aerial photographs, in-situ temperature measurements of shoreline lake sediment, and chemical analyses of surface water and pore water were conducted. Surface-water and pore-water samples were analyzed for major constituents, nutrients, and stable isotopes of oxygen and hydrogen. Bulk precipitation samples were collected and analyzed (1) for nutrient concentrations to determine nutrient input to the lakes through atmospheric deposition and (2) for stable isotope ratios of oxygen and hydrogen to determine a meteoric waterline that was needed for the stable isotope analyses of surface-water and pore-water samples. Total nitrogen concentrations in the precipitation samples ranged from 0.51 to 8.4 mg/L (milligrams per liter) as nitrogen at the North Lake precipitation station and from 0.42 to 2.3 mg/L as nitrogen at the Grand Portage precipitation station. Oxygen-18/oxygen-16 and deuterium/protium isotope ratios for the bulk precipitation samples lie relatively close to a meteoric waterline for northern Wisconsin, except for the ratios for samples collected on May 20, 2004. Analyses of existing aerial photographs, nearshore lake-sediment temperatures, and seasonal isotope ratios of surface-water and pore-water samples were the most valuable data for identifying locations of ground-water inflow and surface-water outseepage. Analyses of existing aerial photographs of the three lakes indicated the location of potential inflow channels and lineaments identifying potential ground-water inflow locations for pore-water sampling. Lake-sediment temperatures at potential ground-water inflow locations ranged from 4 to 16 ?C, varying between lakes, seasons, and climatic conditions. Major constituent chemistry was valuable at Taylor Lake, and to a limited extent at North and Teal Lakes, in confirming results from the isotope and lake-sediment temperature data. Ground-water inflow to North Lake likely occurs along the southwest and south shores, and along portions of the west, southeast, north, and northeast shores. Relatively cool lake-sediment temperatures along the southwest, south, west, and southeast shores, and in isolated beaver channels along the north and northeast shores of North Lake indicate potential ground-water inflow at these locations. Both localized ground-water inflow and surface-water outseepage occurs along portions of the north, northeast, southeast, and south shores, varying seasonally. Conflicting evidence for ground-water flow conditions exist for the northwest and north-northwest pore-water samples. Only minor differences in the major constituent concentrations were seen between the surface-water and pore-water samples from the North Lake area with the exception of iron and manganese concentrations. Ground-water inflow likely takes place along the south-southwest and north shores of Teal Lake, with a mixture of ground-water inflow and surface-water outseepage occurring in other areas of the lake. Cooler lake-sediment temperatures occurred along the south-southwest, west, and northwest shores, portions of the north shore, and in channels identified in aerial photographs throughout the lake, indicating potential ground-water inflow at those locations. Warmer lake-sediment temperatures along the northeast and portions of the southwest and northwest shores of Teal Lake indicate potential locations where surface-water outseepage or little ground- and surface-water interaction occurs. The major constituent concentrations were higher in the pore-water samples collected from the south-southwest and northeast shores of Teal Lake, indicating ground-water inflow.

Minnesota Geological Survey  

NSDL National Science Digital Library

The Minnesota Geological Survey (MGS) was established in 1872 as part of the University of Minnesota. The function of the MGS is to serve "the people of Minnesota by providing systematic geoscience information to support stewardship of water, land, and mineral resources." This website from the Digital Conservancy at the University of Minnesota provides access to all of items published by the MGS. The items are contained within the Collections area, and visitors will find headings here such as "Geology of Minnesota Parks," "County Atlas Series," and the "Bulletin of the Minnesota Geological and Natural History Survey." First-time visitors can check out the Recent Submissions area on the right-hand side of the page to look over some new findings, including hydrogeological maps of different counties around the state. One item that should not be missed is the "Geology of Minnesota: A Centennial Volume" from 1972. It's a tremendous volume and one that cannot be ignored by students of the physical landscape and geological history of the state.

The Minnesota Geological Survey, which was in danger of being closed down due to lack of funding, recently had their $1,075 million budget restored for fiscal 1993. Governor Ann Carlson signed the new bill into law on January 17.“Enactment of this legislation has effectively removed the threat of closure that has hung over our heads since the veto on June 4, 1991,” according to MGS director Priscilla Grew. Carlson vetoed the line item of the 2-year University of Minnesota budget that funds the MGS. The MGS is funded under Minnesota's Higher Education bill, rather than as a state agency.

Minnesota's Historic Shipwrecks  

NSDL National Science Digital Library

Many a sailing vessel has found its way to the bottom of the Great Lakes, and there are hundreds of submerged shipwrecks scattered across the state of Minnesota in Lake Superior and other bodies of water. This website, designed by the Minnesota Historical Society, allows users to learn about these shipwrecks through historic photographs, preservation documents, and maps. Visitors can get started by looking over ships in the "Minnesota Lake Superior Shipwreck Exhibit". Here they will find information about ships like the Thomas Wilson, the Hesper, and the U.S.S. Essex, which now lies underneath the water outside of the Duluth harbor. Each profile contains information about the ship's history, its tonnage, and its current disposition. Moving along, the "Minnesota Lake Superior History" area contains an overview of human activity on the lake, along with information about the vessels that have plied their trade in the area. The site is rounded out by a copy of the state's shipwreck preservation plan.

Avoiding chromosome pathology when replication forks collide.  

PubMed

Chromosome duplication normally initiates through the assembly of replication fork complexes at defined origins. DNA synthesis by any one fork is thought to cease when it meets another travelling in the opposite direction, at which stage the replication machinery may simply dissociate before the nascent strands are finally ligated. But what actually happens is not clear. Here we present evidence consistent with the idea that every fork collision has the potential to threaten genomic integrity. In Escherichia coli this threat is kept at bay by RecG DNA translocase and by single-strand DNA exonucleases. Without RecG, replication initiates where forks meet through a replisome assembly mechanism normally associated with fork repair, replication restart and recombination, establishing new forks with the potential to sustain cell growth and division without an active origin. This potential is realized when roadblocks to fork progression are reduced or eliminated. It relies on the chromosome being circular, reinforcing the idea that replication initiation is triggered repeatedly by fork collision. The results reported raise the question of whether replication fork collisions have pathogenic potential for organisms that exploit several origins to replicate each chromosome. PMID:23892781

Fortunately, many institutions have digitized some (or all) of their map collections and placed them online. The Minnesota Historical Society has created this tremendous collection of land survey maps, plat books and atlases, dating from 1848 to 2001. The search interface for the collection is quite easy to use, as visitors can search the land survey maps by county or township. Those persons who encounter trouble using the search engine can click on a small ÂHelp icon to get more information about performing a detailed search. The plat books and atlases are great fun as well, particularly the illustrated historical atlas of Minnesota from 1874. Through its 394-pages, the atlas contains interesting views of the stateÂs counties, along with sections dedicated to persons of note at the time, including prominent physicians, attorneys, Âpublic menÂ, and lumber dealers. As the preface to this august volume notes, ÂÂwe can conscientiously say that we have strived to make it as near perfect as the circumstances under which we have labored would permit. Truer words have never been spoken.

Hodgson v. Minnesota.

Doctors, clinics, pregnant minors, and the mother of a pregnant minor filed suit in District Court to enjoin enforcement of Minnesota's abortion statute. The plaintiffs objected on due process and equal protection grounds to subdivisions of the statute mandating either that both parents of a minor be notified of her pending abortion, or, in lieu of two-parent notification, that a court authorize the abortion after determining that the minor is capable of giving informed consent. The District Court declared the entire statute unconstitutional. The Court of Appeals reversed, ruling that the provision for judicial bypass of the two-parent notification requirement was valid and saved the statute as a whole. In a 5-4 decision, the U.S. Supreme Court affirmed the Court of Appeals judgment. It concluded that while the two-parent notification requirement in itself violated the Constitution, the statute was rendered constitutional by the judicial bypass provision. PMID:12041294

Human impacts to Minnesota wetlands  

SciTech Connect

Minnesota's 3.6 million ha of wetlands have been impacted by a variety of human activities, including agricultural drainage, urbanization, water control, and nonpoint source pollution. More than half of Minnesota's wetlands have been destroyed since the first European settlers arrived, an average loss of about 35,600 ha/yr. Drainage for agriculture is the major cause of wetland loss in Minnesota, particularly in southern Minnesota and the Red River Valley. In addition to impacting wetlands directly, wetland drainage affects downstream areas by increasing flood flows, and releasing sediment and nutrients. Urban development and highway construction affect a smaller proportion of Minnesota's wetlands, but substantially alter their physical, chemical, and biological properties. Hydrology has a major influence on the structure and function of wetlands, so changes in the frequency, duration, depth, and timing of wetland flooding can severely impact wetlands. While wetlands can assimilate low levels of sediment and nutrient enrichment, excessive inputs can be detrimental. Peat harvesting is not currently extensive in Minnesota, but could cause substantial impacts. Cumulative impact, the incremental impact of an action when added to other past, present, and reasonably forseeable future actions, is becoming an area of increasing concern.

The forked flap repair for hypospadias  

PubMed Central

Context: Despite the abundance of techniques for the repair of Hypospadias, its problems still persist and a satisfactory design to correct the penile curvature with the formation of neourethra from the native urethral tissue or genital or extragenital tissues, with minimal postoperative complications has yet to evolve. Aim: Persisting with such an endeavor, a new technique for the repair of distal and midpenile hypospadias is described. Materials and Methods: The study has been done in 70 cases over the past 11 years. The “Forked-Flap” repair is a single stage method for the repair of such Hypospadias with chordee. It takes advantage of the rich vascular communication at the corona and capitalizes on the established reliability of the meatal based flip–flap. The repair achieves straightening of the curvature of the penis by complete excision of chordee tissue from the ventral surface of the penis beneath the urethral plate. The urethra is reconstructed using the native plate with forked flap extensions and genital tissue relying on the concept of meatal based flaps. Water proofing by dartos tissue and reinforcement by Nesbit's prepucial tissue transfer completes the one stage procedure. Statistical Analysis: An analysis of 70 cases of this single stage technique of repair of penile hypospadias with chordee, operated at 3 to 5 years of age over the past 11 years is presented. Results and Conclusion: The Forked Flap gives comparable and replicable results; except for a urethrocutaneous fistula rate of 4% no other complications were observed.

Direct observation of stalled fork restart via fork regression in the T4 replication system.  

PubMed

The restart of a stalled replication fork is a major challenge for DNA replication. Depending on the nature of the damage, different repair processes might be triggered; one is template switching, which is a bypass of a leading-strand lesion via fork regression. Using magnetic tweezers to study the T4 bacteriophage enzymes, we have reproduced in vitro the complete process of template switching. We show that the UvsW DNA helicase in cooperation with the T4 holoenzyme can overcome leading-strand lesion damage by a pseudostochastic process, periodically forming and migrating a four-way Holliday junction. The initiation of the repair process requires partial replisome disassembly via the departure of the replicative helicase. The results support the role of fork regression pathways in DNA repair.

Elements interfering with the progression of replication forks have been reported to induce rearrangements and/or render homologous recombination essential for viability, in all organisms from bacteria to human. Arrested replication forks may be the target of nucleases, thereby providing a substrate for double-strand break repair enzyme. For example in bacteria, direct fork breakage was proposed to occur at replication forks blocked by a bona fide replication terminator sequence, a specific site that arrests bacterial chromosome replication. Alternatively, an arrested replication fork may be transformed into a recombination substrate by reversal of the forked structures. In reversed forks, the last duplicated portions of the template strands reanneal, allowing the newly synthesized strands to pair. In bacteria, this reaction was proposed to occur in replication mutants, in which fork arrest is caused by a defect in a replication protein, and in UV irradiated cells. Recent studies suggest that it may also occur in eukaryote organisms. We will review here observations that link replication hindrance with DNA rearrangements and the possible underlying molecular processes.

BALD ROCK AND MIDDLE FORK FEATHER RIVER ROADLESS AREAS, CALIFORNIA.  

USGS Publications Warehouse

The results of a mineral-resource assessment of the Bald Rock and Middle Fork Feather River Roadless Areas in California indicate several areas within the Middle Fork Feather River Roadless Area that have probable mineral-resource potential. A probable potential for placer gold exists at various localities, both in areas covered by Tertiary volcanic rocks and in small streams that drain into the Middle Fork of the Feather River. A probable potential for small deposits of chromite exists in tracts underlain by ultramafic rocks in the Melones fault zone. A probable potential for lead-silver deposits is recognized at the east end of the Middle Fork Feather River Roadless Area.

Based on piezoelectric effect of quartz, a design of tuning- fork gyroscopes made of quartz was presented in this paper. The gyroscope is a kind of micro-machined quartz angular rate sensor. Its structure is similar to a tuning fork in quartz watch. In the gyroscope, the piezoelectric effect in quartz is used both to excite a reference vibration in the plane of tuning fork and to detect a vibration normal to this plane due to an externally applied rotation. The amplitude of the second vibration is directly proportional to the angular velocity of the applied rotation. In contrast to ordinary types of tuning fork gyroscopes, this gyroscope uses a single piece of quartz, the sensor element is of a design in which the only vibrationally, active areas are the tines of the tuning fork.

Replication fork barriers in the Xenopus rDNA.  

PubMed

To investigate replication fork progression along the tandemly repeated rRNA genes of Xenopus laevis and Xenopus borealis, rDNA replication intermediates from dividing tissue culture cells were analyzed by two-dimensional gel electrophoresis. Analysis of the direction of replication in the rRNA coding regions revealed replication forks moving in both directions. However, in both frog species, polar replication fork barriers (RFB) arresting forks approaching the rRNA transcription units from downstream were identified. Whereas in X. borealis the RFB maps to a defined site close to the transcription terminator, in X. laevis the arrest of fork movement can occur at multiple positions throughout a 3' flanking repetitive spacer region. A short DNA element located near the respective RFB sites is shared between these two related frog species, suggesting its possible involvement in the arrest of replication fork movement. In a subset of rDNA repeats, these barriers cause an absolute block to replication fork progression, defining the sites where replicon fusion occurs, whereas in the remainder repeats, most probably in the non-transcribed gene copies, the replication machinery can pass the RFB sequences and replicate the rRNA transcription unit in a 3'-to-5' direction.

New interpretation of Clarks Fork field, northern Bighorn basin, Montana  

SciTech Connect

Clarks Fork field is located at the northern edge of the Bighorn basin (T9S, R22E) in Carbon County, Montana. Production was first established in 1944 by General Petroleum Corporation in the Cretaceous Peay Sandstone (basal Frontier) and was later extended to the Cretaceous Greybull (1949) and Lakota (1956) sandstones by British American. Total cumulative hydrocarbons from this field are 1,1789,193 bbl of oil and 3,061,522 mcf of gas, with Lakota sandstones being most productive. Lakota production occurs from a structural-stratigraphic trap in an east-west-trending channel on the axis of Clarks Fork anticline, geographically near the center of the township. Our structural reinterpretation of Clarks Fork field suggests that Elk Basin anticline is a northwest extension of the Elk Basin field anticline. The Elk Basin thrust truncates the north limb of the fold and does not strike to the northwest, as shown by earlier interpretations. They interpret a northwest-striking thrust in the center of the township as a splay off the Elk Basin thrust, and have named it the Clarks Fork thrust. The Clarks Fork anticline is located on the hanging wall of Clarks Fork thrust. Subsurface maps indicate the Clarks Fork area has not been fully developed. Stratigraphic traps in the Lakota and Greybull sandstones are present in several areas of the township. Structural traps in the center and northwest portions of the township may also exist.

ATR phosphorylates SMARCAL1 to prevent replication fork collapse.  

PubMed

The DNA damage response kinase ataxia telangiectasia and Rad3-related (ATR) coordinates much of the cellular response to replication stress. The exact mechanisms by which ATR regulates DNA synthesis in conditions of replication stress are largely unknown, but this activity is critical for the viability and proliferation of cancer cells, making ATR a potential therapeutic target. Here we use selective ATR inhibitors to demonstrate that acute inhibition of ATR kinase activity yields rapid cell lethality, disrupts the timing of replication initiation, slows replication elongation, and induces fork collapse. We define the mechanism of this fork collapse, which includes SLX4-dependent cleavage yielding double-strand breaks and CtIP-dependent resection generating excess single-stranded template and nascent DNA strands. Our data suggest that the DNA substrates of these nucleases are generated at least in part by the SMARCAL1 DNA translocase. Properly regulated SMARCAL1 promotes stalled fork repair and restart; however, unregulated SMARCAL1 contributes to fork collapse when ATR is inactivated in both mammalian and Xenopus systems. ATR phosphorylates SMARCAL1 on S652, thereby limiting its fork regression activities and preventing aberrant fork processing. Thus, phosphorylation of SMARCAL1 is one mechanism by which ATR prevents fork collapse, promotes the completion of DNA replication, and maintains genome integrity. PMID:23873943

The original Fork detector, designed by Los Alamos National Laboratory, used an ion chamber to measure gross gamma count and a fission chamber to measure neutrons from an activation source, {sup 244}Cm. In its review of the draft Topical Report on Burnup Credit, the US Nuclear Regulatory Commission indicated it felt uncomfortable with a measurement system that depended on reactor records for calibration. The Fork+ system was developed at Sandia National Laboratories under the sponsorship of the Electric Power Research Institute with the aim of providing this independent measurement capability. The initial Fork+ prototype was used in a measurement campaign at the Maine Yankee reactor. The campaign confirmed the applicability of the sensor approach in the Fork+ system and the efficiency of the hand-portable Fork+ prototype in making fuel assembly measurements. It also indicated potential design modifications that will be necessary before the Fork+ can be used effectively on high-burnup spent fuel.

Interfacial instability and DNA fork reversal by repair proteins  

NASA Astrophysics Data System (ADS)

A repair protein like RecG moves the stalled replication fork in the direction from the zipped to the unzipped state of DNA. It is proposed here that a softening of the zipped-unzipped interface at the fork results in the front propagating towards the unzipped side. In this scenario, an ordinary helicase destabilizes the zipped state locally near the interface and the fork propagates towards the zipped side. The softening of the interface can be produced by the aromatic interaction, predicted from the crystal structure, between RecG and the nascent broken base pairs at the Y-fork. A numerical analysis of the model also reveals the possibility of a stop and go type motion.

RMI1 promotes DNA replication fork progression and recovery from replication fork stress.  

PubMed

RMI1 is a member of an evolutionarily conserved complex composed of BLM and topoisomerase III? (TopoIII?). This complex exhibits strand passage activity in vitro, which is likely important for DNA repair and DNA replication in vivo. The inactivation of RMI1 causes genome instability, including elevated levels of sister chromatid exchange and accelerated tumorigenesis. Using molecular combing to analyze DNA replication at the single-molecule level, we show that RMI1 is required to promote normal replication fork progression. The fork progression defect in RMI1-depleted cells is alleviated in cells lacking BLM, indicating that RMI1 functions downstream of BLM in promoting replication elongation. RMI1 localizes to subnuclear foci with BLM and TopoIII? in response to replication stress. The proper localization of the complex requires a BLM-TopoIII?-RMI1 interaction and is essential for RMI1 to promote recovery from replication stress. These findings reveal direct roles of RMI1 in DNA replication and the replication stress response, which could explain the molecular basis for its involvement in suppressing sister chromatid exchange and tumorigenesis.

More forks on the road to replication stress recovery  

PubMed Central

High-fidelity replication of DNA, and its accurate segregation to daughter cells, is critical for maintaining genome stability and suppressing cancer. DNA replication forks are stalled by many DNA lesions, activating checkpoint proteins that stabilize stalled forks. Stalled forks may eventually collapse, producing a broken DNA end. Fork restart is typically mediated by proteins initially identified by their roles in homologous recombination repair of DNA double-strand breaks (DSBs). In recent years, several proteins involved in DSB repair by non-homologous end joining (NHEJ) have been implicated in the replication stress response, including DNA-PKcs, Ku, DNA Ligase IV-XRCC4, Artemis, XLF and Metnase. It is currently unclear whether NHEJ proteins are involved in the replication stress response through indirect (signaling) roles, and/or direct roles involving DNA end joining. Additional complexity in the replication stress response centers around RPA, which undergoes significant post-translational modification after stress, and RAD52, a conserved HR protein whose role in DSB repair may have shifted to another protein in higher eukaryotes, such as BRCA2, but retained its role in fork restart. Most cancer therapeutic strategies create DNA replication stress. Thus, it is imperative to gain a better understanding of replication stress response proteins and pathways to improve cancer therapy.

The Middle Pennsylvanian Red Fork sandstone formed as a result of progradation across eastern Kansas and most of Oklahoma. The Red Fork is one of several transgressive-regressive sequences (cyclothems) developed within the Desmoinesian Cherokee Group. Sea level changes, together with varying subsidence, were dominant factors controlling the general stratigraphic (correlative) characteristics of the Red Fork interval. Progradation was episodic, with sand deposition in the more active part of the basin during lower sea level stands and valley-fill deposition in the more stable areas during sea level rises. A map of Red Fork sand trends reveals an alluvial-deltaic complex covering most of Oklahoma. The Red Fork consists primarily of alluvial-valley and plain (fluvial) bodies in the northernmost part of northeastern Oklahoma, alluvial-deltaic bodies in most of the remaining parts of the shelf area, and off-shelf submarine-fan and slope basinal-floor complexes within the deeper part of the Anadarko basin. Determination of reservoir trend and genesis requires integration of rock and log data. Logs need to be calibrated to cores in order to estimate depositional environments accurately and to make a reasonable assessment of diagenetic overprints. Much of the oil and gas has been trapped in stratigraphic traps, and a significant amount of oil is in channel sandstones with trends at high angles to the structural grain. In some areas, secondary clay, in particular chloritic clay, has resulted in microporosity, high water saturation, and correspondingly low resistivities in oil reserves.

Inventory of interbasin water transfers in Minnesota  

USGS Publications Warehouse

Water transfer data were collected by the U.S. Geological Survey , in cooperation with the Minnesota Department of Natural Resources, from the 13 hydrologic subregions in Minnesota. About 30,000 acre-ft of water is exported annually from eight of these subregions. Interbasin transfer of water is classified according to type of water conveyance in Minnesota. This information is needed by water-system managers and planners to develop water budgets for major river basins, to examine the extent of existing interbasin transfers, and to evaluate the feasibility of transferring water to meet regional water demands.

The Replication Checkpoint Protects Fork Stability by Releasing Transcribed Genes from Nuclear Pores  

PubMed Central

Summary Transcription hinders replication fork progression and stability, and the Mec1/ATR checkpoint protects fork integrity. Examining checkpoint-dependent mechanisms controlling fork stability, we find that fork reversal and dormant origin firing due to checkpoint defects are rescued in checkpoint mutants lacking THO, TREX-2, or inner-basket nucleoporins. Gene gating tethers transcribed genes to the nuclear periphery and is counteracted by checkpoint kinases through phosphorylation of nucleoporins such as Mlp1. Checkpoint mutants fail to detach transcribed genes from nuclear pores, thus generating topological impediments for incoming forks. Releasing this topological complexity by introducing a double-strand break between a fork and a transcribed unit prevents fork collapse. Mlp1 mutants mimicking constitutive checkpoint-dependent phosphorylation also alleviate checkpoint defects. We propose that the checkpoint assists fork progression and stability at transcribed genes by phosphorylating key nucleoporins and counteracting gene gating, thus neutralizing the topological tension generated at nuclear pore gated genes.

A multi-fork z-axis quartz micromachined gyroscope.  

PubMed

A novel multi-fork z-axis gyroscope is presented in this paper. Different from traditional quartz gyroscopes, the lateral electrodes of the sense beam can be arranged in simple patterns; as a result, the fabrication is simplified. High sensitivity is achieved by the multi-fork design. The working principles are introduced, while the finite element method (FEM) is used to simulate the modal and sensitivity. A quartz fork is fabricated, and a prototype is assembled. Impedance testing shows that the drive frequency and sense frequency are similar to the simulations, and the quality factor is approximately 10,000 in air. The scale factor is measured to be 18.134 mV/(°/s) and the nonlinearity is 0.40% in a full-scale input range of ±250 °/s. PMID:24048339

Chromatin Immunoprecipitation of Replication Factors Moving with the Replication Fork  

PubMed Central

Summary Replication of chromosomes involves a variety of replication proteins including DNA polymerases, DNA helicases, and other accessory factors. Many of these proteins are known to localize at replication forks and travel with them as components of the replisome complex. Other proteins do not move with replication forks but still play an essential role in DNA replication. Therefore, in order to understand the mechanisms of DNA replication and its controls, it is important to examine localization of each replication factor. Here we describe a chromatin immunoprecipitation (ChIP) method to locate a replication factor at the replication fork. Defining the localization of replication proteins should provide important insight into mechanistic understanding of the regulation of the DNA replication process.

Temperature dependent measurements with a compact fiber coupled sensor for trace gas detection in the near-infrared based on tuning fork enhanced interferometric photoacoustic spectroscopy are presented. The temperature effects on the sensor have been investigated in a range from T = -41°C to T = 107°C, in particular the influence on the resonance frequency and the Q-factor of the micro tuning fork. The refined sensor head contains a combination of a silicon tuning fork and an acoustic off-beam resonator and permits methane detection with a detection limit of S = (3.85 ± 0.01) ppm. The functional capability of a numerical model for the optimization of acoustic off-beam resonators in COMSOL Multiphysics® is presented. PMID:24103964

PRE-FORK SYNTHESIS: A MODEL FOR DNA REPLICATION*  

PubMed Central

A model of DNA replication is presented in which DNA synthesis is continuously initiated from parental strand nicks and occurs, with conservation of helix winding number, ahead of the so-called replicating fork. The fork in this model is the locus of unwinding of already replicated, but presumably unstable, DNA. The model, involving Okazaki's notion of multiple initiation, is based upon the properties of Kornberg's DNA polymerase and accounts for the presence of single-stranded nascent DNA fragments in cell lysates. In addition to acting as sites of initiation, the parental strand nicks are implicated as sites of free rotation allowing unwinding of the replicated DNA.

Characterization of the ATPase Activity of RecG and RuvAB Proteins on Model Fork Structures Reveals Insight into Stalled DNA Replication Fork Repair.  

PubMed

RecG and RuvAB are proposed to act at stalled DNA replication forks to facilitate replication restart. To clarify the roles of these proteins in fork regression, we used a coupled spectrophotometric ATPase assay to determine how these helicases act on two groups of model fork substrates: the first group mimics nascent stalled forks, whereas the second mimics regressed fork structures. The results show that RecG is active on the substrates in group 1, whereas these are poor substrates for RuvAB. In addition, in the presence of group 1 forks, the single-stranded DNA-binding protein (SSB) enhances the activity of RecG and enables it to compete with excess RuvA. In contrast, SSB inhibits the activity of RuvAB on these substrates. Results also show that the preferred regressed fork substrate for RuvAB is a Holliday junction, not a forked DNA. The active form of the enzyme on the Holliday junction contains a single RuvA tetramer. In contrast, although the enzyme is active on a regressed fork structure, RuvB loading by a single RuvA tetramer is impaired, and full activity requires the cooperative binding of two forked DNA substrate molecules. Collectively, the data support a model where RecG is responsible for stalled DNA replication fork regression. SSB ensures that if the nascent fork has single-stranded DNA character RuvAB is inhibited, whereas the activity of RecG is preferentially enhanced. Only once the fork has been regressed and the DNA is relaxed can RuvAB bind to a RecG-extruded Holliday junction. PMID:23893472

Topological challenges to DNA replication: Conformations at the fork  

NASA Astrophysics Data System (ADS)

The unwinding of the parental DNA duplex during replication causes a positive linking number difference, or superhelical strain, to build up around the elongating replication fork. The branching at the fork and this strain bring about different conformations from that of () supercoiled DNA that is not being replicated. The replicating DNA can form (+) precatenanes, in which the daughter DNAs are intertwined, and (+) supercoils. Topoisomerases have the essential role of relieving the superhelical strain by removing these structures. Stalled replication forks of molecules with a (+) superhelical strain have the additional option of regressing,forming a four-way junction at the replication fork. This four-way junction can be acted on by recombination enzymes to restart replication. Replication and chromosome folding are made easier by topological domain barriers, which sequester the substrates for topoisomerases into defined and concentrated regions. Domain barriers also allow replicated DNA to be (-) supercoiled. We discuss the importance of replicating DNA conformations and the roles of topoisomerases, focusing on recent work from our laboratory.

Decomposition in northern Minnesota peatlands  

SciTech Connect

Decomposition in peatlands was investigated in northern Minnesota. Four sites, an ombrotrophic raised bog, an ombrotrophic perched bog and two groundwater minerotrophic fens, were studied. Decomposition rates of peat and paper were estimated using mass-loss techniques. Environmental and substrate factors that were most likely to be responsible for limiting decomposition were monitored. Laboratory incubation experiments complemented the field work. Mass-loss over one year in one of the bogs, ranged from 11 percent in the upper 10 cm of hummocks to 1 percent at 60 to 100 cm depth in hollows. Regression analysis of the data for that bog predicted no mass-loss below 87 cm. Decomposition estimates on an area basis were 2720 and 6460 km/ha yr for the two bogs; 17,000 and 5900 kg/ha yr for the two fens. Environmental factors found to limit decomposition in these peatlands were reducing/anaerobic conditions below the water table and cool peat temperatures. Substrate factors found to limit decomposition were low pH, high content of resistant organics such as lignin, and shortages of available N and K. Greater groundwater influence was found to favor decomposition through raising the pH and perhaps by introducing limited amounts of dissolved oxygen.

Methane flux from Minnesota peatlands  

SciTech Connect

Northern (> 40 deg N) wetlands have been suggested as the largest natural source of methane (CH{sub 4}) to the troposphere. To refine the authors estimates of source strengths from this region and to investigate climatic controls on the process, fluxes were measured from a variety of Minnesota peatlands during May, June, and August 1986. Late spring and summer fluxes ranged from 11 to 866 mg CH{sub 4}/sq/m/day, averaging 207 mg CH{sub 4} sq/m/day overall. At Marcell Forest, forested bogs and fen sites had lower fluxes than open bogs. In the Red Lake peatland, circumneutral fens, with standing water above the peat surface, produced more methane than acid bog sites in which the water table was beneath the moss surface. Peat temperature was an important control. Methane flux increased in response to increasing soil temperature. It is estimated that the methane flux from all peatlands north of 40 deg may be on the order of 70 to 90 Tg/yr though estimates of this sort are plagued by uncertainties in the areal extent of peatlands, length of the CH{sub 4} producing season, and the spatial and temporal variability of the flux. 60 refs., 7 figs., 5 tabs.

Scrap tire recycling in Minnesota  

SciTech Connect

The author discusses the problems associated with scrap tires. For example, surface storing of scrap tires poses a fire hazard and the rainwater trapped in the tire casings is an ideal breeding ground for mosquitoes. Use as a fuel for energy production is unattractive as long as oil retails at its present low price. Past reclamation processes have not met expectations. Legislation alone is not the answer, because scrap tires cannot be regulated out of existence. However, the Minnesota state legislature has come up with an approach that seems to be successful. It has passed the Waste Tire Act, which not only formulates regulations but also provides funding for research and development. Thus, it has established a tire disposal fund for financing construction costs of tire recycling facilities. One of the outcomes was the construction of the St. Louis county Waste Tire Recycling Facility. Through a leasing arrangement with Minneapolis-based Rubber Elastomerics, Inc. (RRE), construction costs financed by the tire disposal fund eventually will be repaid by RRE to the fund. The arrangement is described in detail. By a process also described, RRE produces a product that can be used in thermoset and in thermoplastic compounds. The user can incorporate between 50 percent and 85 percent of the recycled product into a rubber or plastic compound without significantly affecting the physical properties of the compound.

Mechanism of DNA Replication in Drosophila Chromosomes: Structure of Replication Forks and Evidence for Bidirectionality  

PubMed Central

The replicating chromosomal DNA in Drosophila melanogaster cleavage nuclei has been visualized in the electron microscope as a serial array of closely spaced replicated regions created by pairs of diverging replication forks. The fine structure of the forks is very similar to that observed for the replication forks of bidirectionally replicating bacteriophage DNAs. However, the mean length of the single-stranded gaps in Drosophila forks is less than 200 nucleotide residues, much shorter than the gaps in phage forks. This difference in gap length corresponds to the observed difference in the size of Okazaki fragments from Drosophila and phage. Images

Mechanisms of dissipation of an oscillating quartz tuning fork immersed in He II at high pressures  

NASA Astrophysics Data System (ADS)

The dissipative processes that occur with immersing a vibrating tuning fork in superfluid helium are investigated. The tuning forks resonance width ?f of frequencies from 32 to 97 kHz was measured in the temperature range from 0.2 to 2.5 K and He II pressure from SVP to 24.9 atm. Some of the tuning forks were in the original can (closed tuning fork), and for some tuning forks the can was either completely or partially removed (opened fork). We found that for the open tuning forks two dissipation mechanisms are clearly revealed in the temperature dependence of ?f, namely, acoustic radiation and scattering of ballistic thermal excitations at low temperatures, and viscous friction at high temperatures. At low temperatures (below ~ 0.8 K) acoustic dissipation dominates, and the model of quadrupole oscillator for a tuning fork can be applied. We found that acoustic radiation for closed tuning forks is less effective and appears at lower temperatures. The first experimental data on dissipative processes in the quartz tuning fork-He II system at increased liquid pressures are obtained. It is shown that, for high frequency tuning forks the resonance bandwidth decreases with increasing pressure, i.e., with increasing wavelength of sound ?, according to the law ?-5. At low frequencies and low temperatures, with increasing mean free path of thermal excitations the resonance bandwidth is well described by the model of ballistic scattering.

XRCC3 and Rad51 modulate replication fork progression on damaged vertebrate chromosomes.  

PubMed

The mechanisms by which the progression of eukaryotic replication forks is controlled after DNA damage are unclear. We have found that fork progression is slowed by cisplatin or UV treatment in intact vertebrate cells and in replication assays in vitro. Fork slowing is reduced or absent in irs1SF CHO cells and XRCC3(-/-) chicken DT40 cells, indicating that fork slowing is an active process that requires the homologous recombination protein XRCC3. The addition of purified human Rad51C-XRCC3 complex restores fork slowing in permeabilized XRCC3(-/-) cells. Moreover, the requirement for XRCC3 for fork slowing can be circumvented by addition of human Rad51. These data demonstrate that the recombination proteins XRCC3 and Rad51 cooperatively modulate the progression of replication forks on damaged vertebrate chromosomes. PMID:12718895

Methane flux from Minnesota Peatlands  

NASA Astrophysics Data System (ADS)

Northern (>40°N) wetlands have been suggested as the largest natural source of methane (CH4) to the troposphere. To refine our estimates of source strengths from this region and to investigate climatic controls on the process, fluxes were measured from a variety of Minnesota peatlands during May, June, and August 1986. Sites included forested and unforested ombrotrophic bogs and minerotrophic fens in and near the U.S. Department of Agriculture Marcell Experimental Forest and the Red Lake peatlands. Late spring and summer fluxes ranged from 11 to 866 mg CH4 m-2 d-1, averaging 207 mg CH4 m-2 d-1 overall. At Marcell Forest, forested bogs and fen sites had lower fluxes (averages of 77 ± 21 mg CH4 m-2 d-1 and 142 ± 19 mg CH4 m-2 d-1) than open bogs (average of 294 ± 30 mg CH4 m-2 d-1). In the Red Lake peatland, circumneutral fens, with standing water above the peat surface, produced more methane than acid bog sites in which the water table was beneath the moss surface (325 ± 31 and 102 ± 13 mg CH4 m-2 d-1, respectively). Peat temperature was an important control. Methane flux increased in response to increasing soil temperature. For example, the open bog in the Marcell Forest with the highest CH4 flux exhibited a 74-fold increase in flux over a three-fold increase in temperature. We estimate that the methane flux from all peatlands north of 40° may be on the order of 70 to 90 Tg/yr though estimates of this sort are plagued by uncertainties in the areal extent of peatlands, length of the CH4 producing season, and the spatial and temporal variability of the flux.

A description of the hydrologic system and the effects of coal mining on water quality in the East Fork Little Chariton River and the alluvial aquifer between Macon and Huntsville, north-central Missouri  

USGS Publications Warehouse

The quality of surface and groundwater has been affected by abandoned strip mines and by abandoned underground mines in a 110-sq mi subbasin of the East Fork Little Chariton River. More than 14% of the area was strip mined for coal before 1979. The hydrologic system in the area was investigated and the effects of coal mining on quality of water in the river and alluvial aquifer were analyzed, with major emphasis on defining strip-mining effects. The groundwater gradient was from glacial drift or coal spring to alluvium to the East Fork Little Chariton River, and was greatest in spring and least in fall. Seepage from alluvium to the East Fork Little Chariton River occurs throughout the year, except during drought conditions when the only river flow is water released from Long Branch Lake. In the East Fork Little Chariton River median dissolved-solids concentrations increased from 153 mg/L near Macon to 630 mg/L near Huntsville and median sulfate concentrations increased from 36 mg/L near Macon to 360 mg/L near Huntsville. The median dissolved-solids concentration in water from the alluvium increased from 408 mg/L upstream from the strip mines to 641 mg/L near the mines and median dissolved-sulfate concentration increased from 140 to 350 mg/L. The sulfate-to-chloride ratio, used as the most sensitive indicator of strip-mining effects, increased markedly downstream in the East Fork Little Chariton River and nearby Middle Fork Little Chariton River, which also is affected by strip mining. There were no significant increases in sulfate-to-chloride ratio and dissolved-solids concentrations in comparable nearby subbasins of the Grand, Thompson, and Chariton Rivers where there was no mining.

Scanning Probe Microscopy of DNA with a Quartz Tuning Fork  

NASA Astrophysics Data System (ADS)

Quartz tuning-forks have recently been put to use as highly sensitive force detectors in atomic force microscopy (AFM).(F.J.Giessibl et al.), Science 289, 422 (2000). In this study we have applied a home-built, tuning-fork based AFM to the investigation of single and double stranded DNA (ssDNA and dsDNA). We operate the microscope in the non-contact mode (typical tip amplitude ~1 nm) with a variety of tips (e.g. Si, Si_3N_4, W). Here we report on recent results showing that the apparent height of plasmid dsDNA on mica substrates depends on both the tip material and imaging frequency shift. This talk will also review our efforts to probe ssDNA with a chemically functionalized tip. Current and future prospects for this dynamic-mode, chemically-sensitive force microscopy technique will be discussed.

Synthetic Lethality of Cohesins with PARPs and Replication Fork Mediators  

PubMed Central

Synthetic lethality has been proposed as a way to leverage the genetic differences found in tumor cells to affect their selective killing. Cohesins, which tether sister chromatids together until anaphase onset, are mutated in a variety of tumor types. The elucidation of synthetic lethal interactions with cohesin mutants therefore identifies potential therapeutic targets. We used a cross-species approach to identify robust negative genetic interactions with cohesin mutants. Utilizing essential and non-essential mutant synthetic genetic arrays in Saccharomyces cerevisiae, we screened genome-wide for genetic interactions with hypomorphic mutations in cohesin genes. A somatic cell proliferation assay in Caenorhabditis elegans demonstrated that the majority of interactions were conserved. Analysis of the interactions found that cohesin mutants require the function of genes that mediate replication fork progression. Conservation of these interactions between replication fork mediators and cohesin in both yeast and C. elegans prompted us to test whether other replication fork mediators not found in the yeast were required for viability in cohesin mutants. PARP1 has roles in the DNA damage response but also in the restart of stalled replication forks. We found that a hypomorphic allele of the C. elegans SMC1 orthologue, him-1(e879), genetically interacted with mutations in the orthologues of PAR metabolism genes resulting in a reduced brood size and somatic cell defects. We then demonstrated that this interaction is conserved in human cells by showing that PARP inhibitors reduce the viability of cultured human cells depleted for cohesin components. This work demonstrates that large-scale genetic interaction screening in yeast can identify clinically relevant genetic interactions and suggests that PARP inhibitors, which are currently undergoing clinical trials as a treatment of homologous recombination-deficient cancers, may be effective in treating cancers that harbor cohesin mutations.

Replication Fork Reversal after Replication-Transcription Collision  

PubMed Central

Replication fork arrest is a recognized source of genetic instability, and transcription is one of the most prominent causes of replication impediment. We analyze here the requirement for recombination proteins in Escherichia coli when replication–transcription head-on collisions are induced at a specific site by the inversion of a highly expressed ribosomal operon (rrn). RecBC is the only recombination protein required for cell viability under these conditions of increased replication-transcription collisions. In its absence, fork breakage occurs at the site of collision, and the resulting linear DNA is not repaired and is slowly degraded by the RecJ exonuclease. Lethal fork breakage is also observed in cells that lack RecA and RecD, i.e. when both homologous recombination and the potent exonuclease V activity of the RecBCD complex are inactivated, with a slow degradation of the resulting linear DNA by the combined action of the RecBC helicase and the RecJ exonuclease. The sizes of the major linear fragments indicate that DNA degradation is slowed down by the encounter with another rrn operon. The amount of linear DNA decreases nearly two-fold when the Holliday junction resolvase RuvABC is inactivated in recB, as well as in recA recD mutants, indicating that part of the linear DNA is formed by resolution of a Holliday junction. Our results suggest that replication fork reversal occurs after replication–transcription head-on collision, and we propose that it promotes the action of the accessory replicative helicases that dislodge the obstacle.

Human RECQ1 promotes restart of replication forks reversed by DNA topoisomerase I inhibition.  

PubMed

Topoisomerase I (TOP1) inhibitors are an important class of anticancer drugs. The cytotoxicity of TOP1 inhibitors can be modulated by replication fork reversal through a process that requires poly(ADP-ribose) polymerase (PARP) activity. Whether regressed forks can efficiently restart and what factors are required to restart fork progression after fork reversal are still unknown. We have combined biochemical and EM approaches with single-molecule DNA fiber analysis to identify a key role for human RECQ1 helicase in replication fork restart after TOP1 inhibition that is not shared by other human RecQ proteins. We show that the poly(ADP-ribosyl)ation activity of PARP1 stabilizes forks in the regressed state by limiting their restart by RECQ1. These studies provide new mechanistic insights into the roles of RECQ1 and PARP in DNA replication and offer molecular perspectives to potentiate chemotherapeutic regimens based on TOP1 inhibition.

Monitoring Fine Sediment; Grande Ronde and John Day Rivers, 2000 Annual Report.  

SciTech Connect

Fine sediment in spawning substrate has a major effect on salmon survival from egg to smolt. Basin-wide restoration plans have established targets for fine sediment levels in spawning habitat. The project was initiated to monitor surface fine sediment levels and overwinter intrusion of fine sediment in spring chinook salmon spawning habitat in the North Fork John Day (NFJDR) and Grande Ronde Rivers, for five years. The project is also investigating the potential relationship between surface fine levels and overwinter sedimentation. It will provide data to assess trends in substrate conditions in monitored reaches and whether trends are consistent with efforts to improve salmon habitat conditions. The data on the magnitude of overwinter sedimentation will also be used to estimate salmon survival from egg to emergence. In Sept. 1998, 1999, and Aug. 2000, sites for monitoring overwinter sedimentation were established in salmon spawning habitat in the upper Grande Ronde River, Catherine Creek (a Grande Ronde tributary), the North Fork John Day River (NFJDR), and Granite Creek (a NFJDR tributary). Surface fine sediment levels were measured in these reaches via the grid method and visually estimated to test the relative accuracy of these two methods. In 1999 and 2000, surface fine sediment was also estimated via pebble counts at selected reaches to allow comparison of results among the methods. Overwintering substrate samples were collected in April 1999 and April-May 2000 to estimate the amount of overwinter sedimentation in clean gravels in spawning habitat. Monitoring methods and locations are described.

Temperature mediated moose survival in Northeastern Minnesota  

USGS Publications Warehouse

The earth is in the midst of a pronounced warming trend and temperatures in Minnesota, USA, as elsewhere, are projected to increase. Northern Minnesota represents the southern edge to the circumpolar distribution of moose (Alces alces), a species intolerant of heat. Moose increase their metabolic rate to regulate their core body temperature as temperatures rise. We hypothesized that moose survival rates would be a function of the frequency and magnitude that ambient temperatures exceeded the upper critical temperature of moose. We compared annual and seasonal moose survival in northeastern Minnesota between 2002 and 2008 with a temperature metric. We found that models based on January temperatures above the critical threshold were inversely correlated with subsequent survival and explained >78 of variability in spring, fall, and annual survival. Models based on late-spring temperatures also explained a high proportion of survival during the subsequent fall. A model based on warm-season temperatures was important in explaining survival during the subsequent winter. Our analyses suggest that temperatures may have a cumulative influence on survival. We expect that continuation or acceleration of current climate trends will result in decreased survival, a decrease in moose density, and ultimately, a retreat of moose northward from their current distribution.

Grand alliance HDTV  

NASA Astrophysics Data System (ADS)

Terrestrial broadcast television in the United States has remained essentially unchanged in the last fifty years except for the addition of color and stereo sound. Today, personal computers are addressing the need for random access of high resolution images and CD quality audio. Furthermore, advances in digital video compression and digital communication technology have cleared the way toward offering high resolution video and audio services to consumers using traditional analog communications channels. In 1987, the U.S. Federal Communications Commission (FCC) chartered an advisory committee to recommend an advanced television system for the United States. From 1990 to 1992, the Advanced Television Test Center tested four all-digital systems, one analog High Definition Television (HDTV) system, and one enhancement NTSC system using broadcast and cable television environment simulators. The formation of the HDTV Grand Alliance in May of 1993 resulted from the withdrawal of the only analog HDTV system from the competition and a stalemate between the other four all- digital systems. The HDTV Grand Alliance system is composed of the best components from previously competing digital systems demonstrated to the FCC. Moving Pictures Experts Group (MPEG-2) syntax is used with novel encoding techniques to deliver a set of video scanning formats for a variety of applications. This paper describes the important features and concepts embodied in the HDTV Grand Alliance system.

Substrate-selective repair and restart of replication forks by DNA translocases  

PubMed Central

SUMMARY Stalled replication forks are sources of genetic instability. Multiple fork remodeling enzymes are recruited to stalled forks, but how they work to promote fork restart is poorly understood. By combining ensemble biochemical assays and single molecule studies with magnetic tweezers, we show that SMARCAL1 branch migration and DNA annealing activities are directed by the single-stranded DNA binding protein RPA to selectively regress stalled replication forks caused by blockage to the leading-strand polymerase and to restore normal replication forks with a lagging-strand gap. We unveil the molecular mechanisms by which RPA enforces SMARCAL1 substrate preference. E. coli RecG acts similarly to SMARCAL1 in the presence of E. coli SSB, whereas the highly related human protein ZRANB3 has different substrate preferences. Our findings identify the important substrates of SMARCAL1 in fork repair, suggest that RecG and SMARCAL1 are functional orthologues, and provide a comprehensive model of fork repair by these DNA translocases.

Replication fork stalling by bulky DNA damage: localization at active origins and checkpoint modulation  

PubMed Central

The integrity of the genome is threatened by DNA damage that blocks the progression of replication forks. Little is known about the genomic locations of replication fork stalling, and its determinants and consequences in vivo. Here we show that bulky DNA damaging agents induce localized fork stalling at yeast replication origins, and that localized stalling is dependent on proximal origin activity and is modulated by the intra–S–phase checkpoint. Fork stalling preceded the formation of sister chromatid junctions required for bypassing DNA damage. Despite DNA adduct formation, localized fork stalling was abrogated at an origin inactivated by a point mutation and prominent stalling was not detected at naturally-inactive origins in the replicon. The intra–S–phase checkpoint contributed to the high-level of fork stalling at early origins, while checkpoint inactivation led to initiation, localized stalling and chromatid joining at a late origin. Our results indicate that replication forks initially encountering a bulky DNA adduct exhibit a dual nature of stalling: a checkpoint-independent arrest that triggers sister chromatid junction formation, as well as a checkpoint-enhanced arrest at early origins that accompanies the repression of late origin firing. We propose that the initial checkpoint-enhanced arrest reflects events that facilitate fork resolution at subsequent lesions.

Replication fork movement and methylation govern SeqA binding to the Escherichia coli chromosome  

PubMed Central

In Escherichia coli, the SeqA protein binds specifically to GATC sequences which are methylated on the A of the old strand but not on the new strand. Such hemimethylated DNA is produced by progression of the replication forks and lasts until Dam methyltransferase methylates the new strand. It is therefore believed that a region of hemimethylated DNA covered by SeqA follows the replication fork. We show that this is, indeed, the case by using global ChIP on Chip analysis of SeqA in cells synchronized regarding DNA replication. To assess hemimethylation, we developed the first genome-wide method for methylation analysis in bacteria. Since loss of the SeqA protein affects growth rate only during rapid growth when cells contain multiple replication forks, a comparison of rapid and slow growth was performed. In cells with six replication forks per chromosome, the two old forks were found to bind surprisingly little SeqA protein. Cell cycle analysis showed that loss of SeqA from the old forks did not occur at initiation of the new forks, but instead occurs at a time point coinciding with the end of SeqA-dependent origin sequestration. The finding suggests simultaneous origin de-sequestration and loss of SeqA from old replication forks.

Continued DNA Synthesis in Replication Checkpoint Mutants Leads to Fork Collapse  

PubMed Central

Hydroxyurea (HU) treatment activates the intra-S phase checkpoint proteins Cds1 and Mrc1 to prevent replication fork collapse. We found that prolonged DNA synthesis occurs in cds1? and mrc1? checkpoint mutants in the presence of HU and continues after release. This is coincident with increased DNA damage measured by phosphorylated histone H2A in whole cells during release. High-resolution live-cell imaging shows that mutants first accumulate extensive replication protein A (RPA) foci, followed by increased Rad52. Both DNA synthesis and RPA accumulation require the MCM helicase. We propose that a replication fork “collapse point” in HU-treated cells describes the point at which accumulated DNA damage and instability at individual forks prevent further replication. After this point, cds1? and mrc1? forks cannot complete genome replication. These observations establish replication fork collapse as a dynamic process that continues after release from HU block.

FANCJ couples replication past natural fork barriers with maintenance of chromatin structure  

PubMed Central

Defective DNA repair causes Fanconi anemia (FA), a rare childhood cancer–predisposing syndrome. At least 15 genes are known to be mutated in FA; however, their role in DNA repair remains unclear. Here, we show that the FANCJ helicase promotes DNA replication in trans by counteracting fork stalling on replication barriers, such as G4 quadruplex structures. Accordingly, stabilization of G4 quadruplexes in ?FANCJ cells restricts fork movements, uncouples leading- and lagging-strand synthesis and generates small single-stranded DNA gaps behind the fork. Unexpectedly, we also discovered that FANCJ suppresses heterochromatin spreading by coupling fork movement through replication barriers with maintenance of chromatin structure. We propose that FANCJ plays an essential role in counteracting chromatin compaction associated with unscheduled replication fork stalling and restart, and suppresses tumorigenesis, at least partially, in this replication-specific manner.

Improve performance of scanning probe microscopy by balancing tuning fork prongs.  

PubMed

This paper presents an approach for improving the Q-factor of tuning fork probe used in scanning probe microscopes. The improvement is achieved by balancing the fork prongs with extra mass attachment. An analytical model is proposed to characterize the Q-factor of a tuning fork probe with respect to the attachment of extra mass on the tuning fork prongs, and based on the model, the Q-factors of the unbalanced and balanced tuning fork probes are derived and compared. Experimental results showed that the model fits well the experimental data and the approach can improve the Q-factor by more than a factor of three. The effectiveness of the approach is further demonstrated by applying the balanced probe on an atomic force microscope to obtain improved topographic images. PMID:19193492

Deletions at stalled replication forks occur by two different pathways.  

PubMed

Replication blockage induces non-homologous deletions in Escherichia coli. The mechanism of the formation of these deletions was investigated. A pBR322-mini-oriC hybrid plasmid carrying two E. coli replication terminators (Ter sites) in opposite orientations was used. Deletions which remove at least the pBR322 blocking site (named Ter1) occurred at a frequency of 2 x 10(-6) per generation. They fall into two equally large classes: deletions that join sequences with no homology, and others that join sequences of 3-10 bp of homology. Some 95% of the deletions in the former class resulted from the fusion of sequences immediately preceding the two Ter sites, indicating a direct role for blocked replication forks in their formation. These deletions were not found in a topA10 mutant, suggesting a topoisomerase I-mediated process. In contrast, deletions joining short homologous sequences were not affected by the topA10 mutation. However, the incidence of this second class of deletions increased 10-fold in a recD mutant, devoid of exonuclease V activity. This indicates that linear molecules are intermediates in their formation. In addition, approximately 50% of these deletions were clustered in the region flanking the Ter1 site. We propose that they are produced by repair of molecules broken at the blocked replication forks. PMID:9214648

Depositional environments, reservoir trends, and diagenesis of Red Fork sandstones in parts of Blaine, Caddo, and Custer counties, Oklahoma  

SciTech Connect

The Red Fork sandstone was divided into the upper and lower Red Fork which are separated by a consistent marker bed. The Red Fork interval thickens markedly across the study area from 250 ft (75 m) in the northeast to over 1300 ft (400 m) in the southwest. Most of the thickening is within the lower Red Fork. The lower Red Fork is believed to have been deposited in shelf-to-basin transitional terrain. Sands were located in delta-front, submarine-channel-fill, and possible submarine-fan terrain. The upper Red Fork is believed to represent the maximum progradation of a deltaic complex. Sandstones of the lower Red Fork are sublithic to lithic arenites; the upper Red Fork is sublithic arenite. The dominant lithic fraction is mudstone fragments. The main diagenetic alterations of both the upper and lower Red Fork sandstones were destruction of primary porosity by compaction and cementation. Dissolution chiefly of mud fragments has produced well-developed secondary porosity. Clays of the lower Red Fork mainly are authigenic chlorite; clays of the upper Red Fork primarily are authigenic kaolinite. Present oil and gas production from Red Fork sandstones is most abundant from localities on the paleoshelf.

Minnesota`s experience using shingle scrap in bituminous pavements. Final report, 1991-1996  

SciTech Connect

The Minnesota Department of Transportation (Mn/DOT) has experimented with the use of shingle scrap in hot mix asphalt (HMA) since 1990. To date, the source of the shingle scrap has been shingle manufacturers exclusively. The manufactured shingle scrap consists primarily of tab punch-outs but also contains some mis-colored and damaged shingles. Test sections were constructed on the Willard Munger Recreational Trail, T.H. 25 in Mayer, Minnesota and on County State Aid Highway (CSAH) 17, in Scott County, Minnesota. Not only are the test sections performing as well as the control sections, but using shingle scrap reduces the amount of virgin asphalt cement required in a bituminous mix, thus creating the potential for a cost savings when using shingle scrap in HMA. Based on the performance of these test sections, shingle manufacturing scrap is now an allowable salvage material in hot mix asphalt under Mn/DOT specification 2331.E2e, Recycled Mixture Requirements. This report outlines the history of shingle scrap use in Minnesota, presents laboratory and field performance data and contains the current Mn/DOT specifications allowing shingle scrap to be used as a salvage material in HMA pavements.

This prospective comparative study was conducted to determine the incidence of grand multiparity, compare the maternal outcome of grand multiparity to low parity and identify the frequency of maternal mortality associated with obstetrical complications of grand multiparity. It was carried out in the Obstetric and Gynaecology department of Rangpur Medical College Hospital, Rangpur, during the period of 1st January to 30th September' 2003. All pregnant (>28 weeks) parous women were included and primigravida were excluded. A total 2728 pregnant patients were initially recruited on the study. From them 200 cases were randomly selected. Among them 100 cases were grand multipara (parity 4 and above) comprising study groups and 100 cases were non grand multipara (parity 1-3) consisting of control group. All relevant maternal parameter were recorded and then compared between study group and control group. According to this study the incidence of grand multiparity is 9.8%. Among the grand multipara patient 95% were suffering from anaemia of different severity (p<0.05). The incidence of hypertension and gestational diabetes in grand multipara were significantly higher than non grand multipara (45% vs. 12%) and (12% vs. 02%) respectively. The other complications like placenta praevia, abruptio placentae, multiple pregnancy, malpresentations, postpartum haemorrhage, ruptured uterus were significantly higher among grand multipara and statistically significant results were observed. Proportion of women who underwent caesarean section was also high in study group (32% vs. 21% p<0.05). During the study period 7 maternal death were observed in grand multipara and 1 maternal death in non grand multipara (p<0.05). PMID:21804498

Dynamics of quartz tuning fork force sensors used in scanning probe microscopy  

NASA Astrophysics Data System (ADS)

We have performed an experimental characterization of the dynamics of oscillating quartz tuning forks which are being increasingly used in scanning probe microscopy as force sensors. We show that tuning forks can be described as a system of coupled oscillators. Nevertheless, this description requires knowledge of the elastic coupling constant between the prongs of the tuning fork, which has not yet been measured. Therefore, tuning forks have usually been described within the single oscillator or the weakly coupled oscillators approximation that neglects the coupling between the prongs. We propose three different procedures to measure the elastic coupling constant: an opto-mechanical method, a variation of the Cleveland method and a thermal noise based method. We find that the coupling between the quartz tuning fork prongs has a strong influence on the dynamics and the measured motion is in remarkable agreement with a simple model of coupled harmonic oscillators. The precise determination of the elastic coupling between the prongs of a tuning fork allows us to obtain a quantitative relation between the resonance frequency shift and the force gradient acting at the free end of a tuning fork prong.

Separate roles for the DNA damage checkpoint protein kinases in stabilizing DNA replication forks  

PubMed Central

The DNA damage checkpoint plays a crucial role in maintaining functional DNA replication forks when cells are exposed to genotoxic agents. In budding yeast, the protein kinases Mec1 (ATR) and Rad53 (Chk2) are especially important in this process. How these kinases act to stabilize DNA replication forks is currently unknown but is likely to have important implications for understanding how genomic instability is generated during oncogenesis and how chemotherapies that interfere with DNA replication could be improved. Here we show that the sensitivity of rad53 mutants to DNA-damaging agents can be almost completely suppressed by deletion of the EXO1 gene, which encodes an enigmatic flap endonuclease. Deletion of EXO1 also suppresses DNA replication fork instability in rad53 mutants. Surprisingly, deletion of EXO1 is completely ineffective in suppressing both the sensitivity and replication fork breakdown in mec1 mutants, indicating that Mec1 has a genetically separable role in replication fork stabilization from Rad53. Finally, our analysis indicates that a second downstream effector kinase, Chk1, can stabilize replication forks in the absence of Rad53. These results reveal previously unappreciated complexity in the downstream targets of the checkpoint kinases and provide a framework for elucidating the mechanisms of DNA replication fork stabilization by these kinases.

Molecular anatomy and regulation of a stable replisome at a paused eukaryotic DNA replication fork  

PubMed Central

Eukaryotic cells regulate the progression and integrity of DNA replication forks to maintain genomic stability and couple DNA synthesis to other processes. The budding yeast proteins Mrc1 and Tof1 associate with the putative MCM–Cdc45 helicase and limit progression of the replisome when nucleotides are depleted, and the checkpoint kinases Mec1 and Rad53 stabilize such stalled forks and prevent disassembly of the replisome. Forks also pause transiently during unperturbed chromosome replication, at sites where nonnucleosomal proteins bind DNA tightly. We describe a method for inducing prolonged pausing of forks at protein barriers assembled at unique sites on a yeast chromosome, allowing us to examine for the first time the effects of pausing upon replisome integrity. We show that paused forks maintain an intact replisome that contains Mrc1, Tof1, MCM–Cdc45, GINS, and DNA polymerases ? and ? and that recruits the Rrm3 helicase. Surprisingly, pausing does not require Mrc1, although Tof1 and Csm3 are both important. In addition, the integrity of the paused forks does not require Mec1, Rad53, or recombination. We also show that paused forks at analogous barriers in the rDNA are regulated similarly. These data indicate that paused and stalled eukaryotic replisomes resemble each other but are regulated differently.

Karst database development in Minnesota: Design and data assembly  

USGS Publications Warehouse

The Karst Feature Database (KFD) of Minnesota is a relational GIS-based Database Management System (DBMS). Previous karst feature datasets used inconsistent attributes to describe karst features in different areas of Minnesota. Existing metadata were modified and standardized to represent a comprehensive metadata for all the karst features in Minnesota. Microsoft Access 2000 and ArcView 3.2 were used to develop this working database. Existing county and sub-county karst feature datasets have been assembled into the KFD, which is capable of visualizing and analyzing the entire data set. By November 17 2002, 11,682 karst features were stored in the KFD of Minnesota. Data tables are stored in a Microsoft Access 2000 DBMS and linked to corresponding ArcView applications. The current KFD of Minnesota has been moved from a Windows NT server to a Windows 2000 Citrix server accessible to researchers and planners through networked interfaces. ?? Springer-Verlag 2005.

Mercury contamination in East Fork Poplar Creek and Bear Creek  

SciTech Connect

A one-month study was performed to determine the concentration of mercury in sediment, fish, moss, and pasture grass in the East Fork Poplar Creek (EFPC) and Bear Creek drainages and to determine whether mercury is still being released from the Y-12 Plant. Total mercury concentration in a sediment core from New Hope Pond was 100 ..mu..g/g dry wt at the surface and up to 300 ..mu..g/g dry wt in subsurface sediments, relative to background concentrations of less than 0.3 ..mu..g/g dry wt. There has been an apparent decrease since 1973 in mercury concentration of sediment entering New Hope Pond. Total mercury concentration in muscle tissue of bluegill from EFPC was positively correlated with body weight, as expected. Total mercury concentration averaged 3.5 and 0.2 ..mu..g/g fresh wt for dead and live foliage in pasture grass, respectively, on the flood plain of EFPC. Results for Bear Creek indicate that this drainage is considerably less contaminated with mercury than East Fork Poplar Creek. The concentration in the sediment was 13 ..mu..g/g dry wt near the settling basins at the west end of the Y-12 Plant area, but decreased to background concentrations before the confluence of Bear Creek with EFPC. Total mercury concentration in fish, except for one rock bass, did not exceed the FDA action level. Recommendations are made (1) to limit the quantity of mercury released from the Y-12 Plant area into EFPC, (2) to consider notifying the responsible state agencies and fishermen concerning mercury concentrations found in fish in EFPC, and (3) to measure mercury concentration in hair from cattle grazing on pasture grasses along EFPC. Recommendations concerning further monitoring are also made. 15 references, 3 figures, 8 tables.

Measuring the Orbital Angular Momentum of Electron Vortex Beams Using a Forked Grating  

NASA Astrophysics Data System (ADS)

The present study experimentally examines how an electron vortex beam with orbital angular momentum (OAM) undergoes diffraction through a forked grating. The nth-order diffracted electron vortex beam after passing through a forked grating with a Burgers vector of 1 shows an OAM transfer of n?. Hence, the diffraction patterns become mirror asymmetric owing to the size difference between the electron beams. Such a forked grating, when used in combination with a pinhole located at the diffraction plane, could act as an analyzer to measure the OAM of input electrons.

An improved dynamic model of tuning fork probe for scanning probe microscopy.  

PubMed

This paper presents a two coupled oscillators model to describe the dynamics of a tuning fork with a probe attached. The two coupled oscillators are unbalanced only in their effective masses and the damping ratios. By applying a frequency domain system identification approach in experimental investigation of various probe attachment cases, a good accuracy of the model is demonstrated. The effectiveness of the model is further demonstrated in quantitative analysis of the noise performance and the sensitivity of force sensing with a tuning fork probe. Compared with existing models, the proposed model can more accurately characterize the dynamics of a tuning fork probe. PMID:19397747

The DNA helicase Pfh1 promotes fork merging at replication termination sites to ensure genome stability  

PubMed Central

Bidirectionally moving DNA replication forks merge at termination sites composed of accidental or programmed DNA–protein barriers. If merging fails, then regions of unreplicated DNA can result in the breakage of DNA during mitosis, which in turn can give rise to genome instability. Despite its importance, little is known about the mechanisms that promote the final stages of fork merging in eukaryotes. Here we show that the Pif1 family DNA helicase Pfh1 plays a dual role in promoting replication fork termination. First, it facilitates replication past DNA–protein barriers, and second, it promotes the merging of replication forks. A failure of these processes in Pfh1-deficient cells results in aberrant chromosome segregation and heightened genome instability.

Hysteresis, Switching and Anomalous Behaviour of a Quartz Tuning Fork in Superfluid 4He  

NASA Astrophysics Data System (ADS)

We have been studying the behaviour of commercial quartz tuning forks immersed in superfluid 4He and driven at resonance. For one of the forks we have observed hysteresis and switching between linear and non-linear damping regimes at temperatures below 10 mK. We associate linear damping with pure potential flow around the prongs of the fork, and non-linear damping with the production of vortex lines in a turbulent regime. At appropriate prong velocities, we have observed metastability of both the linear and the turbulent flow states, and a region of intermittency where the flow switched back and forth between each state. For the same fork, we have also observed anomalous behaviour in the linear regime, with large excursions in both damping, resonant frequency, and the tip velocity as a function of driving force.

Artemis-dependent DNA double-strand break formation at stalled replication forks.  

PubMed

Stalled replication forks undergo DNA double-strand breaks (DSBs) under certain conditions. However, the precise mechanism underlying DSB induction and the cellular response to persistent replication fork stalling are not fully understood. Here we show that, in response to hydroxyurea exposure, DSBs are generated in an Artemis nuclease-dependent manner following prolonged stalling with subsequent activation of the ataxia-telangiectasia mutated (ATM) signaling pathway. The kinase activity of the catalytic subunit of the DNA-dependent protein kinase, a prerequisite for stimulation of the endonuclease activity of Artemis, is also required for DSB generation and subsequent ATM activation. Our findings indicate a novel function of Artemis as a molecular switch that converts stalled replication forks harboring single-stranded gap DNA lesions into DSBs, thereby activating the ATM signaling pathway following prolonged replication fork stalling.

Community solutions to violence: a Minnesota managed care action plan.  

PubMed

Reducing violence is a critical health and economic priority. In Minnesota, as in other parts of the United States, violence is increasingly viewed as a public health problem. Helping people work together to prevent violence is one way that managed care organizations are collaborating with public health to improve the health of communities. In 1994, Blue Cross and Blue Shield of Minnesota worked with community organizations to develop The Minnesota Action Plan to End Gun Violence, a broad-based solution to a community problem: violence in Minnesota. The goal of this initiative was to develop grassroots solutions to violence and to inspire community members to take action. Outcomes of the initiative included: participation by over 1,000 Minnesotans in 12 community violence prevention forums; a widely distributed action plan; Students Stop Guns, a school-based intervention to keep Minnesota schools gun-free; the Governor's Task Force on Violence as a Public Health Problem, which led to a commitment of resources to prevent violence and respond to the victims and consequences of violence, and the Health Care Coalition on Violence, to institutionalize strategies within the Minnesota health care environment. The project's qualitative evaluation resulted in lessons and advice on how to execute a collaborative health improvement initiative. These lessons have been widely shared with Minnesota community health advocates. PMID:9566945

Minnesota Heat Flow and Geothermal Potential  

NASA Astrophysics Data System (ADS)

Radiogenic heat production, bedrock geology, gravity, magnetics, and heat flow were combined to study heat flow and geothermal energy potential in Minnesota. Heat production was determined from one-hundred 800 kg samples collected at outcrops and from drill cores by gamma ray spectrometry. Small splits of the samples were also analyzed by chemical methods for K, U, and Th. Heat production averaged 2.6 W m-1 K-1 ± 2.0 for 42 felsic samples and 0.9 W m-1 K-1 ± 0.6 for 58 mafic samples. Areal variation in heat production measured with a portable gamma ray spectrometer was compared to bedrock geology and gravity and magnetic anomaly patterns. Gravity lows and magnetic highs correlate with higher heat production and vice versa. Prior to this study heat flow was reported for only four borehole sites in Minnesota. Those sites were located in Keweenawan mafic rocks of the mid-continent rift and heat flow values averaged 39 ± 6 mW m-2. These low heat flows are consistent with a heat flow study conducted in Lake Superior that showed a trough of low heat flow (19.2 - 41.0 mW m-2) along the northern edge of the lake. Thirty-one new heat flow determinations in the mafic rocks obtained from borehole temperature measurements in mining holes average (34.1 mW m-2 ± 1.9 mW m-2). However, paleoclimate signals evident in the temperature vs. depth profiles indicate that the temperature gradients are at least 27 percent low and heat flow is likely 46.7 mW m-2. Based on a reduced heat flow of 32 mW m-2 and a depth parameter of 10 km, the heat flow heat production relation yields a heat flow value of 58 mW m-2 in the felsic regions in Minnesota. These heat flow values suggest that EGS with a binary power plant would be achievable in the felsic regions.

A variable fork rate affects timing of origin firing and S phase dynamics in Saccharomyces cerevisiae.  

PubMed

Activation (in the following referred to as firing) of replication origins is a continuous and irreversible process regulated by availability of DNA replication molecules and cyclin-dependent kinase activities, which are often altered in human cancers. The temporal, progressive origin firing throughout S phase appears as a characteristic replication profile, and computational models have been developed to describe this process. Although evidence from yeast to human indicates that a range of replication fork rates is observed experimentally in order to complete a timely S phase, those models incorporate velocities that are uniform across the genome. Taking advantage of the availability of replication profiles, chromosomal position and replication timing, here we investigated how fork rate may affect origin firing in budding yeast. Our analysis suggested that patterns of origin firing can be observed from a modulation of the fork rate that strongly correlates with origin density. Replication profiles of chromosomes with a low origin density were fitted with a variable fork rate, whereas for the ones with a high origin density a constant fork rate was appropriate. This indeed supports the previously reported correlation between inter-origin distance and fork rate changes. Intriguingly, the calculated correlation between fork rate and timing of origin firing allowed the estimation of firing efficiencies for the replication origins. This approach correctly retrieved origin efficiencies previously determined for chromosome VI and provided testable prediction for other chromosomal origins. Our results gain deeper insights into the temporal coordination of genome duplication, indicating that control of the replication fork rate is required for the timely origin firing during S phase.

Scanning optical homodyne detection of high-frequency picoscale resonances in cantilever and tuning fork sensors  

Microsoft Academic Search

Higher harmonic modes in nanoscale silicon cantilevers and microscale quartz tuning forks are detected and characterized using a custom scanning optical homodyne interferometer. Capable of both mass and force sensing, these resonators exhibit high-frequency harmonic motion content with picometer-scale amplitudes detected in a 2.5 MHz bandwidth, driven by ambient thermal radiation. Quartz tuning forks additionally display both in-plane and out-of-plane

Symmetrically arranged quartz tuning fork with soft cantilever for intermittent contact mode atomic force microscopy  

NASA Astrophysics Data System (ADS)

A self-sensing and -actuating probe for dynamic mode atomic force microscopy (AFM) based on a commercial quartz tuning fork and a microfabricated cantilever is presented. The U-shaped cantilever, exhibiting a sharp tip, is combined with the tuning fork in a symmetrical arrangement, such that each of the two legs of the cantilever is fixed to one of the prongs of the tuning fork. The tuning fork is used as an oscillatory force sensor. Its frequency and amplitude govern that of the tip vibration, while the cantilever determines the spring constant of the whole probe. The frequency of the tip vibration for AFM operations can be much higher than the resonance frequency of the cantilever. A probe comprising a silicon nitride cantilever (0.1 N/m) is used to image monoatomic terraces of graphite in the intermittent contact mode. A much softer cantilever (0.01 N/m) is used to analyze the topography of a microelectronic chip in the same mode. Moreover, a bacterial surface layer hexagonally packed intermediate layer of Deinococcus radiodurans is imaged in a buffer solution. The tip vibration was again generated by the tuning fork while the sample interaction was measured using the standard optical detection scheme in this experiment. These probes are suited for batch fabrication and assembly and, therefore, enlarge the applications for the tuning fork based AFM.

RNF4 and PLK1 are required for replication fork collapse in ATR-deficient cells.  

PubMed

The ATR-CHK1 axis stabilizes stalled replication forks and prevents their collapse into DNA double-strand breaks (DSBs). Here, we show that fork collapse in Atr-deleted cells is mediated through the combined effects the sumo targeted E3-ubiquitin ligase RNF4 and activation of the AURKA-PLK1 pathway. As indicated previously, Atr-deleted cells exhibited a decreased ability to restart DNA replication following fork stalling in comparison with control cells. However, suppression of RNF4, AURKA, or PLK1 returned the reinitiation of replication in Atr-deleted cells to near wild-type levels. In RNF4-depleted cells, this rescue directly correlated with the persistence of sumoylation of chromatin-bound factors. Notably, RNF4 repression substantially suppressed the accumulation of DSBs in ATR-deficient cells, and this decrease in breaks was enhanced by concomitant inhibition of PLK1. DSBs resulting from ATR inhibition were also observed to be dependent on the endonuclease scaffold protein SLX4, suggesting that RNF4 and PLK1 either help activate the SLX4 complex or make DNA replication fork structures accessible for subsequent SLX4-dependent cleavage. Thus, replication fork collapse following ATR inhibition is a multistep process that disrupts replisome function and permits cleavage of the replication fork. PMID:24142876

SMARCAL1 catalyzes fork regression and Holliday junction migration to maintain genome stability during DNA replication  

PubMed Central

SMARCAL1 (SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily A-like1) maintains genome integrity during DNA replication. Here we investigated its mechanism of action. We found that SMARCAL1 travels with elongating replication forks, and its absence leads to MUS81-dependent double-strand break formation. Binding to specific nucleic acid substrates activates SMARCAL1 activity in a reaction that requires its HARP2 (Hep-A-related protein 2) domain. Homology modeling indicates that the HARP domain is similar in structure to the DNA-binding domain of the PUR proteins. Limited proteolysis, small-angle X-ray scattering, and functional assays indicate that the core enzymatic unit consists of the HARP2 and ATPase domains that fold into a stable structure. Surprisingly, SMARCAL1 is capable of binding three-way and four-way Holliday junctions and model replication forks that lack a designed ssDNA region. Furthermore, SMARCAL1 remodels these DNA substrates by promoting branch migration and fork regression. SMARCAL1 mutations that cause Schimke immunoosseous dysplasia or that inactivate the HARP2 domain abrogate these activities. These results suggest that SMARCAL1 continuously surveys replication forks for damage. If damage is present, it remodels the fork to promote repair and restart. Failures in the process lead to activation of an alternative repair mechanism that depends on MUS81-catalyzed cleavage of the damaged fork.

Course on Grand Unification  

NASA Astrophysics Data System (ADS)

Although this is a field with a long history and a number of excellent reviews I tried to make this self contained, thus the section devoted to the group theory of SU(N) and SO(2N). For a newcomer in the field, this is must in my opinion. The material on spinors in SO(2N) is especially useful, and simple examples of SO(2), SO(4) and SO(6) are given in some detail. This should enable the reader to follow the physics and mathematics of spinors in SO(10) later on. The sections on SU(5) and Left-Right symmetry are fairly pedagogical and the reader armed with the knowledge of the first section should have no problems in following them. The last section devoted to the SO(10) theory, probably the most motived grand unified theory starts out being pedagogical, but the part which addresses the phenomenology of the ordinary and supersymmetric version is somewhat more difficult. If found too hard, it should be skipped in the first reading. It could be useful though for those interested in fermion masses and mixings. Throughout the text, I have included some exercises which I recommend.

222Rn variations in Mystery Cave, Minnesota  

USGS Publications Warehouse

222Rn concentrations and meteorological parameters were measured at 4- h intervals over a 2-y period in Mystery Cave, southeastern Minnesota. Continuous radon monitors and meteorological sensors connected to data loggers were installed at several locations along commercial tour routes. 222Rn concentrations ranged as high as 25 kBq m-3 in summer and 20 kBq m-3 in winter. Average winter concentrations were lower than summer by at least a factor of two. Seasonal radon variations were correlative with outside air temperatures. During the winter, radon concentrations were observed to fluctuate periodically by factors of 20 or more in under 24 h. Both the long- and short-term variations are correlative with temperature- induced mixing of cave air with surface air.

Bioavailability of mercury in East Fork Poplar Creek soils  

SciTech Connect

The initial risk assessment for the East Fork Poplar Creek (EFPC) floodplain in Oak Ridge, Tennessee, a superfund site heavily contaminated with mercury, was based upon a reference dose for mercuric chloride, a soluble mercury compound not expected to be present in the floodplain, which is frequently saturated with water. Previous investigations had suggested mercury in the EFPC floodplain was less soluble and therefore less bioavailable than mercuric chloride, possibly making the results of the risk assessment unduly conservative. A bioavailability study, designed to measure the amount of mercury available for absorption in a child`s digestive tract, the most critical risk endpoint and pathway, was performed on twenty soils from the EFPC floodplain. The average percentage of mercury released during the study for the twenty soils was 5.3%, compared to 100% of the compound mercuric chloride subjected to the same conditions. Alteration of the procedure to test additional conditions possible during soil digestion did not appreciably alter the results. Therefore, use of a reference dose for mercuric chloride in the EFPC risk assessment without inclusion of a corresponding bioavailability factor may be unduly conservative.

[Heritability of body weight and fork length for Oncorhynchus masou masou].  

PubMed

Body weight and body length have been considered as the most important production traits for the fish genetic improvement. For cold-water fish, body length was usually substituted by fork length. In order to estimate the heritability of body weight and fork length of the sixth generation Oncorhynchus masou masou, which was introduced into China, the method of unbalanced nest design and an artificial insemination technigue were used. Twenty-nine full-sib families and fourteen half-sib families were obtained. Body weight and fork length of O. masou masou were measured in 12 and 24 months after fertilization. Based on full-sib and half-sib families data, the causal components of phenotypic variance were calculated. The results showed that, (1) during the whole growth phase of O. masou masou, the coefficient variation (CV) of fork length was higher than body weight, and CV of 12-month old was higher than that of 24-month old; (2) body weight and fork length of O. masou masou among sires and dams among sires were significant difference (P<0.01) both at 12 months and at 24 months; (3) the maternal component estimates were significantly larger than those of paternal ones for body weight and fork length traits both at 12 months and at 24 months; (4) for 12 months of O. masou masou the heritabilities of body weight and fork length were 0.41~0.51 and 0.46~0.54, respectively. For 24 months the values were 0.55~0.60 and 0.53~0.59, respectively; and (5) it was concluded that the heritability of growth traits in O. masou masou was relatively high and this highlights the potential to improve its growth through selective breeding. This study shows important data supporting for further genetic improvement of O. masou masou. PMID:23448933

BLM SUMOylation regulates ssDNA accumulation at stalled replication forks.  

PubMed

Polymerase stalling results in uncoupling of DNA polymerase and the replicative helicase, which generates single-stranded DNA (ssDNA). After stalling, RAD51 accumulates at stalled replication forks to stabilize the fork and to repair by homologous recombination (HR) double-strand breaks (DSBs) that accumulate there. We showed recently that SUMO modification of the BLM helicase is required in order for RAD51 to accumulate at stalled forks. In order to investigate how BLM SUMOylation controls RAD51 accumulation, we characterized the function of HR proteins and ssDNA-binding protein RPA in cells that stably expressed either normal BLM (BLM+) or SUMO-mutant BLM (SM-BLM). In HU-treated SM-BLM cells, mediators BRCA2 and RAD52, which normally substitute RAD51 for RPA on ssDNA, failed to accumulate normally at stalled forks; instead, excess RPA accumulated. SM-BLM cells also exhibited higher levels of HU-induced chromatin-bound RPA than BLM+ cells did. The excess RPA did not result from excessive intrinsic BLM helicase activity, because in vitro SUMOylated BLM unwound similar amounts of replication-fork substrate as unSUMOylated BLM. Nor did BLM SUMOylation inhibit binding of RPA to BLM in vitro; however, in immunoprecipitation experiments, more BLM-RPA complex formed in HU-treated SM-BLM cells, indicating that BLM SUMOylation controls the amount of BLM-RPA complex normally formed at stalled forks. Together, these results showed that BLM SUMOylation regulates the amount of ssDNA that accumulates during polymerase stalling. We conclude that BLM SUMOylation functions as a licensing mechanism that permits and regulates HR at damaged replication forks. PMID:24027577

Biological Monitoring Program for East Fork Poplar Creek  

SciTech Connect

In May 1985, a National Pollutant Discharge Elimination System (NPDES) permit was issued for the Oak Ridge Y-12 Plant. As a condition of the permit, a Biologicai Monitoring and Abatement Program (BMAP) was developed to demonstrate that the effluent limitations established for the Y-12 Plant protect the classified uses of the receiving stream (East Fork Poplar Creek; EFPC), in particular, the growth and propagation of aquatic life (Lear et al. 1989). A second objective of the BMAP is to document the ecological effects resulting from the implementation of a water pollution control program designed to eliminate direct discharges of wastewaters to EFPC and to minimize the inadvertent release of pollutants to the environment. Because of the compiex nature of the discharges to EFPC and the temporal and spatial variability in the composition of the discharges, a comprehensive, integrated approach to biological monitoring was developed. A new permit was issued to the Y-12 Plant on April 28, 1995 and became effective on July 1, 1995. Biological monitoring continues to be required under the new permit. The BMAP consists of four major tasks that reflect different but complementary approaches to evaluating the effects of the Y-12 Plant discharges on the aquatic integrity of EFPC, These tasks are (1) toxicity monitoring, (2) biological indicator studies, (3) bioaccumuiation studies, and (4) ecological surveys of the periphyton, benthic macro invertebrate, and fish communities. Monitoring is currently being conducted at five sites, although sites maybe excluded and/or others added depending upon the specific objectives of the various tasks. Criteria used in selecting the sites include: (1) location of sampling sites used in other studies, (2) known or suspected sources of downstream impacts, (3) proximity to U.S. Department of Energy (DOE) Oak Ridge Reservation (ORR) boundaries, (4) concentration of mercury in the adjacent floodplain, (5) appropriate habitat distribution, and (6) access. The sampling sites include upper EFPC at kilometers (EFKs) 24.4 and 23.4 [upstream and downstream of Lake Reality (LR) respectively]; EFK 18.7 (also EFK 18 and 19), iocated off the ORR and below an area of intensive commercial and limited light industrial development; EFK 13.8 (also EFK 14), located upstream from the Oak Ridge Wastewater Treatment Facility (ORWTF); and EFK 6.3 located approximately 1.4 km below the ORR boundary (Fig. 1.1 ). Other sampling sites on EFPC are utilized as appropriate for individual tasks. Brushy Fork (BF) at kilometer (BFK) 7.6 is used as a reference stream in most tasks of the BMAP. Additional sites off the ORR are also occasional 1 y used for reference, including Beaver Creek, Bull Run, Hinds Creek, Paint Rock Creek, and the Einory River in Watts Bar Reservoir (Fig. 1.2).

CENP-B preserves genome integrity at replication forks paused by Retrotransposon LTR  

PubMed Central

Centromere-binding protein B (CENP-B) is a widely conserved DNA binding factor associated with heterochromatin and centromeric satellite repeats1. In fission yeast, CENP-B homologs have been shown to silence Long Terminal Repeat (LTR) retrotransposons by recruiting histone deacetylases2. However, CENP-B factors also have unexplained roles in DNA replication3, 4. Here, we show that a molecular function of CENP-B is to promote replication fork progression through the LTR. Mutants have increased genomic instability caused by replication fork blockage that depends on the DNA binding factor Switch Activating Protein 1 (Sap1), which is directly recruited by the LTR. The loss of Sap1-dependent barrier activity allows the unhindered progression of the replication fork, but results in rearrangements deleterious to the retrotransposon. We conclude that retrotransposons influence replication polarity through recruitment of Sap1 and transposition near replication fork blocks, while CENP-B counteracts this activity and promotes fork stability. Our results may account for the role of LTR in fragile sites, and for the association of CENP-B with pericentromeric heterochromatin and tandem satellite repeats.

Human RECQ5? helicase promotes strand exchange on synthetic DNA structures resembling a stalled replication fork  

PubMed Central

The role of the human RECQ5? helicase in the maintenance of genomic stability remains elusive. Here we show that RECQ5? promotes strand exchange between arms of synthetic forked DNA structures resembling a stalled replication fork in a reaction dependent on ATP hydrolysis. BLM and WRN can also promote strand exchange on these structures. However, in the presence of human replication protein A (hRPA), the action of these RecQ-type helicases is strongly biased towards unwinding of the parental duplex, an effect not seen with RECQ5?. A domain within the non-conserved portion of RECQ5? is identified as being important for its ability to unwind the lagging-strand arm and to promote strand exchange on hRPA-coated forked structures. We also show that RECQ5? associates with DNA replication factories in S phase nuclei and persists at the sites of stalled replication forks after exposure of cells to UV irradiation. Moreover, RECQ5? is found to physically interact with the polymerase processivity factor proliferating cell nuclear antigen in vitro and in vivo. Collectively, these findings suggest that RECQ5? may promote regression of stalled replication forks to facilitate the bypass of replication-blocking lesions by template-switching. Loss of such activity could explain the elevated level of mitotic crossovers observed in RECQ5?-deficient cells.

South Fork Snake River/Palisades Wildlife Mitigation Project: Environmental assessment  

SciTech Connect

BPA proposes to fund the implementation of the South Fork Snake River Programmatic Management Plan to compensate for losses of wildlife and wildlife habitat due to hydroelectric development at Palisades Dam. The Idaho Department of Fish and Game drafted the plan, which was completed in May 1993. This plan recommends land and conservation easement acquisition and wildlife habitat enhancement measures. These measures would be implemented on selected lands along the South Fork of the Snake River between Palisades Dam and the confluence with the Henry`s Fork, and on portions of the Henry`s Fork located in Bonneville, Madison, and Jefferson Counties, Idaho. BPA has prepared an Environmental Assessment evaluating the proposed project. The EA also incorporates by reference the analyses in the South Fork Snake River Activity/Operations Plan and EA prepared jointly in 1991 by the Bureau of Land Management and the Forest Service. Based on the analysis in the EA, BPA has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an Environmental Impact Statement (EIS) is not required and BPA is issuing this FONSI.

Distinct roles for Sld3 and GINS during establishment and progression of eukaryotic DNA replication forks  

PubMed Central

The Cdc45 protein is crucial for the initiation of chromosome replication in eukaryotic cells, as it allows the activation of prereplication complexes (pre-RCs) that contain the MCM helicase. This causes the unwinding of origins and the establishment of DNA replication forks. The incorporation of Cdc45 at nascent forks is a highly regulated and poorly understood process that requires, in budding yeast, the Sld3 protein and the GINS complex. Previous studies suggested that Sld3 is also important for the progression of DNA replication forks after the initiation step, as are Cdc45 and GINS. In contrast, we show here that Sld3 does not move with DNA replication forks and only associates with MCM in an unstable manner before initiation. After the establishment of DNA replication forks from early origins, Sld3 is no longer essential for the completion of chromosome replication. Unlike Sld3, GINS is not required for the initial recruitment of Cdc45 to origins and instead is necessary for stable engagement of Cdc45 with the nascent replisome. Like Cdc45, GINS then associates stably with MCM during S-phase.

Modeling streamflow response from Minnesota peatlands  

SciTech Connect

To aid in the development of Minnesota's 7 million acres of peatlands, and to evaluate the hydrologic impacts and reclamation options associated with such development, a Peatland Hydrologic Impact Model (PHIM) was devised. PHIM is a deterministic, continuous simulation model designed to simulate streamflow resulting from rainfall and snowmelt under both natural and altered (mined) conditions. It is largely physically based and requires watershed information and hydrometeorological data that are usually available in an operational setting. PHIM can provide both daily and hourly estimates of streamflow, PHIM consists of 5 submodels, 3 land type submodels for natural peatlands, mined peatlands and mineral soil uplands and 2 routing submodels for channel reaches and reservoirs. Streamflow from headwater peatland watersheds can be simulated by combining the submodels in the order that best describes the basin. The model was tested on the basis of stormflow events form a 3758 ha undisturbed peatland and a 155 ha peatland that had undergone ditching and peat mining for horticultural purposes. Simulated streamflow volumes averaged 86 and 91% of observed volumes for the undisturbed and mined area, respectively. Peat discharges were simulated within 84 and 65% of observed values, respectively.

Decrease in smoking prevalence--Minnesota, 1999-2010.  

PubMed

Following the landmark 1998 settlement of the lawsuit, State of Minnesota versus Philip Morris, Inc., et al., Minnesota implemented a series of tobacco control efforts to limit the harm caused by tobacco use. In 2001, quitline services for tobacco users without health insurance coverage for cessation services were introduced and statewide mass media campaigns publicizing them were initiated. In 2005, Minnesota imposed a $0.75 per pack tax on cigarettes, followed in 2009 by a $0.62 per pack increase in federal excise tax, contributing in large part to a more than $2 increase in the average price of cigarettes. In 2007, a comprehensive, statewide smoke-free law was passed. Using surveillance data from the Minnesota Adult Tobacco Survey (MATS) and cigarette pack sales data, this report examines the effects of these tobacco-related public health efforts. Compared with a 15% decline in national adult smoking prevalence since 1999, adult smoking prevalence in Minnesota decreased 27.1%, from 22.1% in 1999 to 16.1% in 2010. During the same period, per capita cigarette sales in Minnesota decreased 40%. In addition, in 2010 compared with 1999, a higher percentage of adults reported that smoking was restricted in their homes (87.2% versus 64.5%), and adults were less likely to report exposure to secondhand smoke (45.6% versus 67.2%). In the past decade, Minnesota has benefited from sustained tobacco control. Future progress in decreasing adult smoking and reducing exposure to secondhand smoke will depend on a concerted effort across the public health community to keep tobacco control a priority.

Flavor tests of grand unification  

SciTech Connect

How will we ever be convinced that grand unification, or string theory, or some other physics at very high energies, is correct? Two ways in which this could happen are: The structure of the theory is itself so compelling and tightly constrained, and the links to observed particle interactions are sufficiently strong, that the theory is convincing and is accepted as the standard viewpoint. String theory is a candidate for such a theory, but connections to known physics will require much further understanding of the breaking of its many symmetries. The theory predicts new physics beyond the standard model, which is discovered. If the structure of the theory is not very tightly constrained, several such predictions will be necessary for it to become convincing. Grand unification is a candidate for such a theory, but as yet there have been no discoveries beyond the standard model. Supersymmetric grand unified theories do have a constrained gauge structure, and this has led to the successful prediction of the weak mixing angle at the percent level of accuracy While significant, this is hardly convincing. Never-the-less, supersymmetric grand unified theories offer the prospect of many further tests. In this talk I make the case that experiments of this decade, and the next, allow for the possibility that we might become convinced that grand unification is correct.

SU(6) grand unified model  

SciTech Connect

A model of grand unified theory based on SU(6) gauge group is proposed. It can accommodate two generations of ordinary fermions with V-A weak coupling and two generations of weird fermions with V+A weak coupling. In this model, a new discrete symmetry is introduced that insures existence of fermions with lower masses when SU(6) gauge symmetry is spontaneously broken. Simple Higgs fields with appropriate vacuum expectation values are chosen, so that the masses of weird fermions are heavier than those of ordinary fermions. This model also gives the same value of Weinberg angle, sin sq of Theta/sub w/ = 3/8, as in the usual SU(5) grand unified model at the grand unified scale.

Dysregulation of DNA polymerase ? recruitment to replication forks results in genomic instability  

PubMed Central

Translesion synthesis polymerases (TLS Pols) are required to tolerate DNA lesions that would otherwise cause replication arrest and cell death. Aberrant expression of these specialized Pols may be responsible for increased mutagenesis and loss of genome integrity in human cancers. The molecular events that control the usage of TLS Pols in non-pathological conditions remain largely unknown. Here, we show that aberrant recruitment of TLS Pol? to replication forks results in genomic instability and can be mediated through the loss of the deubiquitinase USP1. Moreover, artificial tethering of Pol? to proliferating cell nuclear antigen (PCNA) circumvents the need for its ubiquitin-binding domain in the promotion of genomic instability. Finally, we show that the loss of USP1 leads to a dramatic reduction of replication fork speed in a Pol?-dependent manner. We propose a mechanism whereby reversible ubiquitination of PCNA can prevent spurious TLS Pol recruitment and regulate replication fork speed to ensure the maintenance of genome integrity.

Are "knife and fork" good enough for day case surgery of resistant tennis elbow?  

PubMed

This observational retrospective study was performed on 22 consecutive patients treated surgically in a day surgery unit for resistant tennis elbow to ascertain the effectiveness of the "knife and fork" procedure. All patients had an unfavourable response to nonsurgical treatment lasting at least six months. A simple and inexpensive "knife and fork" technique yielded excellent results in 90.5% of patients and a high percentage (95.2%) of satisfied patients at an average follow-up of two years. There were no fair or poor results and no complications. We conclude that the "knife and fork" technique is a simple and dependable day case procedure. In the present National Health Service (NHS) era of tariff and "payment by results", this approach is more cost effective than an arthroscopic alternative. PMID:19096844

FANCD2 regulates BLM complex functions independently of FANCI to promote replication fork recovery.  

PubMed

Fanconi Anemia (FA) and Bloom Syndrome share overlapping phenotypes including spontaneous chromosomal abnormalities and increased cancer predisposition. The FA protein pathway comprises an upstream core complex that mediates recruitment of two central players, FANCD2 and FANCI, to sites of stalled replication forks. Successful fork recovery depends on the Bloom's helicase BLM that participates in a larger protein complex ('BLMcx') containing topoisomerase III alpha, RMI1, RMI2 and replication protein A. We show that FANCD2 is an essential regulator of BLMcx functions: it maintains BLM protein stability and is crucial for complete BLMcx assembly; moreover, it recruits BLMcx to replicating chromatin during normal S-phase and mediates phosphorylation of BLMcx members in response to DNA damage. During replication stress, FANCD2 and BLM cooperate to promote restart of stalled replication forks while suppressing firing of new replication origins. In contrast, FANCI is dispensable for FANCD2-dependent BLMcx regulation, demonstrating functional separation of FANCD2 from FANCI. PMID:23658231

A study of a quartz tuning fork as a force sensor  

NASA Astrophysics Data System (ADS)

Force sensing cantilevers used for dynamic force microscopy (DFM) should have a high quality factor, stiffness, and resonant frequency. Quartz tuning forks (used in watches) satisfy these conditions well. Following the work of Giessibl [1], we are developing a force sensor based upon a quartz tuning fork. The displacement of the piezoelectric tuning fork is sensed using a Wein bridge circuit. We have characterized the properties of the force sensor. The frequency f0 is 32768 Hz, the stiffness k is 1800 Nt/m and the Q factor is approximately 3000. The minimum detectable sensor displacement and force at the resonance frequency will be discussed in terms of thermal and system noise. A comparison between the measured and simulated response will be presented. [1]F.J.Giessibl Appl.Phys.Lett. 76, 1470 (2000)

Ground-water aspects of the lower Henrys Fork region, Idaho  

USGS Publications Warehouse

The lower Henrys Fork region includes the plains and low benches between Ashton and the junction of Henrys Fork and Snake River in eastern Idaho. The northwestern and western parts of the area are part of the Snake River lava plain. The central part of the area is occupied by alluvial plains of the Snake, Teton, and Falls Rivers, and Henrys Fork. The southeastern part of the area is a bench (Rexburg Bench), chiefly on silicic and basaltic volcanic rocks, which rises gradually to mountain peaks southeast of the area. The basalt, and the sand and gravel under the alluvial plains are good aquifers and yield large amounts of water with small drawdowns. The silicic volcanic rocks and the interbedded ash, pyroclastics, and sedimentary deposits generally yield much less water than the basalt and alluvium.

Tobacco industry documents: comparing the Minnesota Depository and internet access  

PubMed Central

Objective: To assess the comparability of searches conducted on two publicly available tobacco industry document collections: hard copies housed and maintained by a neutral party in the Minnesota Depository and electronic copies available through tobacco industry maintained websites. Methods: We conducted a set of searches in Minnesota and then conducted the same searches using the industry websites. We matched documents by Bates number, weeded out duplicates, and coded documents that were unique to either collection as major, minor, or trivial. Results: Among hundreds of documents produced by several searches, we found only four unique major documents in the Minnesota Depository. By contrast, we found 62 unique major documents using the websites. Conclusion: These results suggest that researchers can rely on industry websites while waiting for improved access resulting from searching, indexing, and document storage administered by the tobacco control community. Searching the tobacco industry websites is at least as good as searching in Minnesota and may in some instances actually be better. Four smaller subcollections, however, can only be searched by hand in Minnesota.

We present a short review of the multitude of applications of the commercially produced quartz tuning fork in cryogenic ?uid dynamics, using cold gaseous, normal liquid and super?uid 4He as working ?uids with extraordinary, but well-known and tunable physical properties. While the central focus of this work is the use of the tuning fork as a detector of classical and quantum turbulence, we also report other studies and applications, mainly on cavitation, pressure-, thermo- and viscosimetry. Finally, we mention brie?y our recent studies of the acoustic emission due to these high-Q oscillators and its effect on the characteristics of their resonance.

The development of a low-noise variable-temperature preamplifier for self-sensing piezoelectric tuning fork force sensors is presented. The preamplifier utilizes a pair of commercially available GaAs field effect transistors to achieve high impedance and low noise over a wide range of temperatures. Using a standard 32 kHz quartz tuning fork, the base noise level achieved is 20 dB below the thermal noise resonance at room temperature and at 4.2 K. The circuit diagram, biasing points, and noise specifications are presented, and the application for variable temperature scanning probe microscopy is discussed.

Replication Fork Stability Is Essential for the Maintenance of Centromere Integrity in the Absence of Heterochromatin  

PubMed Central

Summary The centromere of many eukaryotes contains highly repetitive sequences marked by methylation of histone H3K9 by Clr4KMT1. This recruits multiple heterochromatin proteins including Swi6 and Chp1 to form a rigid centromere and ensure accurate chromosome segregation. In the absence of heterochromatin, cells show increased rate of recombination in the centromere, and chromosome loss. These defects are severely aggravated by loss of replication fork stability. Thus, heterochromatin proteins and replication fork protection mechanisms work in concert to prevent abnormal recombination, preserve centromere integrity, and ensure faithful chromosome segregation.

Wolf depredation on livestock in Minnesota  

USGS Publications Warehouse

Depredation by wolves (Canis lupus) on cattle, sheep, and other livestock in Minnesota currently is a minor problem except to a few individual farmers. Indices to the seriousness of the problem are available only from recent years, so historical trends cannot be detected. From 1976 through 1980 the number of farms in the wolf range suffering verified losses to wolves ranged from 9 to 19 (mean of x = 13) per year out of about 12,230. From 1977 through 1980, the highest cattle losses claimed by farmers were 0.45 per 1,000 cattle available in 1979; the highest sheep losses claimed were 1.18 per 1,000 available in 1980. Many claims of losses (especially of calves) are based on missing animals, and few wolves are involved in the verified losses. Most losses occur in summer when livestock are released to graze in open and wooded pasture. Herd management practices, such as calving in forested or brushy pastures and disposal of carcasses in or near pastures, are responsible for many instances of wolf depredation. Failure to distinguish wolves from coyotes (Canis latrans) has contributed to an exaggerated view of the importance of wolves as livestock predators. Recently the number of wolves killed in depredation control has declined, whereas the number of livestock killed has remained fairly stable. Results of the U.S. Fish and Wildlife Service's depredation- control program in 1979 and 1980 suggest that highly restricted trapping, coupled with other management methods, has potential for reducing both livestock losses and the number of wolves that need to be killed.

Cancer mortality in agricultural regions of Minnesota.  

PubMed Central

Because of its unique geology, Minnesota can be divided into four agricultural regions: south-central region one (corn, soybeans); west-central region two (wheat, corn, soybeans); northwest region three (wheat, sugar beets, potatoes); and northeast region four (forested and urban in character). Cancer mortality (1980-1989) in agricultural regions one, two, and three was compared to region four. Using data compiled by the National Center for Health Statistics, cancer mortality was summarized by 5-year age groups, sex, race, and county. Age-standardized mortality rate ratios were calculated for white males and females for all ages combined, and for children aged 0-14. Increased mortality rate ratios and 95% confidence intervals (CIs) were observed for the following cancer sites: region one--lip (men), standardized rate ratio (SRR) = 2.70 (CI, 1.08-6.71); nasopharynx (women), SRR = 3.35 (CI, 1.20-9.31); region two--non-Hodgkin's lymphoma (women), SRR = 1.35 (CI, 1.09-1.66); and region three--prostate (men), SRR = 1.12 (CI, 1.00-1.26); thyroid (men), SRR = 2.95 (CI, 1.35-6.44); bone (men), SRR = 2.09 (CI, 1. 00-4.34); eye (women), SRR = 5.77 (CI, 1.90-17.50). Deficits of smoking-related cancers were noted. Excess cancers reported are consistent with earlier reports of agriculturally related cancers in the midwestern United States. However, reports on thyroid and bone cancer in association with agricultural pesticides are few in number. The highest use of fungicides occurs in region three. Ethylenebisdithiocarbamates, whose metabolite is a known cause of thyroid cancer in rats, are frequently applied. This report provides a rationale for evaluation of the carcinogenic potential of this suspect agent in humans. Images Figure 1

Channelization and floodplain forests: Impacts of accelerated sedimentation and valley plug formation on floodplain forests of the Middle Fork Forked Deer River, Tennessee, USA  

USGS Publications Warehouse

We evaluated the severe degradation of floodplain habitats resulting from channelization and concomitant excessive coarse sedimentation on the Middle Fork Forked Deer River in west Tennessee from 2000 to 2003. Land use practices have resulted in excessive sediment in the tributaries and river system eventually resulting in sand deposition on the floodplain, increased overbank flooding, a rise in the groundwater table, and ponding of upstream timber. Our objectives were to: (1) determine the composition of floodplain vegetation communities along the degraded river reach, (2) to isolate relationships among these communities, geomorphic features, and environmental variables and (3) evaluate successional changes based on current stand conditions. Vegetation communities were not specifically associated with predefined geomorphic features; nevertheless, hydrologic and geomorphic processes as a result of channelization have clearly affected vegetation communities. The presence of valley plugs and continued degradation of upstream reaches and tributaries on the impacted study reach has arrested recovery of floodplain plant communities. Historically common species like Liquidambar styraciflua L. and Quercus spp. L. were not important, with importance values (IV) less than 1, and occurred in less than 20% of forested plots, while Acer rubrum L., a disturbance-tolerant species, was the most important species on the site (IV = 78.1) and occurred in 87% of forested plots. The results of this study also indicate that channelization impacts on the Middle Fork Forked Deer River are more temporally and spatially complex than previously described for other river systems. Rehabilitation of this system necessitates a long-term, landscape-scale solution that addresses watershed rehabilitation in a spatially and temporally hierarchical manner. ?? 2005 Elsevier B.V.

Extending GIS Technology to Study Karst Features of Southeastern Minnesota  

NASA Astrophysics Data System (ADS)

This paper summarizes ongoing research on karst feature distribution of southeastern Minnesota. The main goals of this interdisciplinary research are: 1) to look for large-scale patterns in the rate and distribution of sinkhole development; 2) to conduct statistical tests of hypotheses about the formation of sinkholes; 3) to create management tools for land-use managers and planners; and 4) to deliver geomorphic and hydrogeologic criteria for making scientifically valid land-use policies and ethical decisions in karst areas of southeastern Minnesota. Existing county and sub-county karst feature datasets of southeastern Minnesota have been assembled into a large GIS-based database capable of analyzing the entire data set. The central database management system (DBMS) is a relational GIS-based system interacting with three modules: GIS, statistical and hydrogeologic modules. ArcInfo and ArcView were used to generate a series of 2D and 3D maps depicting karst feature distributions in southeastern Minnesota. IRIS ExplorerTM was used to produce satisfying 3D maps and animations using data exported from GIS-based database. Nearest-neighbor analysis has been used to test sinkhole distributions in different topographic and geologic settings. All current nearest-neighbor analyses testify that sinkholes in southeastern Minnesota are not evenly distributed in this area (i.e., they tend to be clustered). More detailed statistical methods such as cluster analysis, histograms, probability estimation, correlation and regression have been used to study the spatial distributions of some mapped karst features of southeastern Minnesota. A sinkhole probability map for Goodhue County has been constructed based on sinkhole distribution, bedrock geology, depth to bedrock, GIS buffer analysis and nearest-neighbor analysis. A series of karst features for Winona County including sinkholes, springs, seeps, stream sinks and outcrop has been mapped and entered into the Karst Feature Database of Southeastern Minnesota. The Karst Feature Database of Winona County is being expanded to include all the mapped karst features of southeastern Minnesota. Air photos from 1930s to 1990s of Spring Valley Cavern Area in Fillmore County were scanned and geo-referenced into our GIS system. This technology has been proved to be very useful to identify sinkholes and study the rate of sinkhole development.

The development of the Minnesota Multiphasic Personality Inventory.  

PubMed

The Minnesota Multiphasic Personality Inventory (MMPI) was constructed at the University of Minnesota before and during World War II. In its developmental phase, the MMPI was conceptualized as an efficient way of detecting psychiatric disturbance. The test's construction was made possible by atypical cooperation between psychologists and psychiatrists, within the context of a crisis in the U.S. public mental health care system. The MMPI was designed to meet the diagnostic needs of psychiatrists. As such, it represented the operationalization of medical hegemony. However, the interpretation of the MMPI shifted significantly after the war, reflecting organizational reform in clinical psychology and changing professional relationships between psychologists and psychiatrists.

Geologic map of the Dillon quadrangle, Summit and Grand Counties, Colorado  

USGS Publications Warehouse

New 1:24,000-scale geologic mapping along the Interstate-70 urban corridor in western Colorado, in support of the USGS Central Region State/USGS Cooperative Geologic Mapping Project, is contributing to a more complete understanding of the stratigraphy, structure, tectonic evolution, and hazard potential of this rapidly developing region. The 1:24,000-scale Dillon quadrangle is near the headwaters of the Blue River and straddles features of the Blue River graben (Kellogg, 1999), part of the northernmost reaches of the Rio Grande rift, a major late Oligocene to recent zone of extension that extends from Colorado to Mexico. The Williams Range thrust fault, the western structural margin of the Colorado Front Range, cuts through the center of the quadrangle, although is mostly covered by surficial deposits. The oldest rocks in the quadrangle underlie the Williams Fork Mountains and the ridge immediately east of South Fork Middle Fork River, and include biotite-sillimanite schist and gneiss, amphibolite, and migmatite that are intruded by granite inferred to be part of the 1,667-1,750 Ma Routt Plutonic Suite (Tweto, 1987). The oldest exposed sedimentary unit is the Upper Jurassic Morrison Formation, but Pennsylvanian Maroon Formation, a sequence of red sandstone, conglomerate, and interbedded shale, underlies the southern part of the quadrangle. The thickest sequence of sedimentary rocks is Cretaceous in age and includes at least 500 m of the Upper Cretaceous Pierre Shale. Surficial deposits include (1) an old, deeply dissected landslide deposit, possibly as old as Pliocene, on the west flank of the Williams Fork Mountains, (2) deeply weathered, very coarse gravel deposits underlying a mesa in the southwest part of the quadrangle (the Mesa Cortina subdivision. The gravels are gold bearing and were mined by hydraulic methods in the 1800s), (3) moderately to deeply weathered, widespread, bouldery material that is a combination of till of the Bull Lake glaciation, debris-flow deposits, landslide deposits, and possibly pre-Bull Lake till, (4) glacial deposits of both Bull Lake (middle Pleistocene) and Pinedale (late Pleistocene)glaciations, (5) recent landslide deposits, and (6)extensive colluvial and alluvial deposits.

Protein-DNA complexes are the primary sources of replication fork pausing in Escherichia coli  

PubMed Central

Replication fork pausing drives genome instability, because any loss of paused replisome activity creates a requirement for reloading of the replication machinery, a potentially mutagenic process. Despite this importance, the relative contributions to fork pausing of different replicative barriers remain unknown. We show here that Deinococcus radiodurans RecD2 helicase inactivates Escherichia coli replisomes that are paused but still functional in vitro, preventing continued fork movement upon barrier removal or bypass, but does not inactivate elongating forks. Using RecD2 to probe replisome pausing in vivo, we demonstrate that most pausing events do not lead to replisome inactivation, that transcription complexes are the primary sources of this pausing, and that an accessory replicative helicase is critical for minimizing the frequency and/or duration of replisome pauses. These findings reveal the hidden potential for replisome inactivation, and hence genome instability, inside cells. They also demonstrate that efficient chromosome duplication requires mechanisms that aid resumption of replication by paused replisomes, especially those halted by protein–DNA barriers such as transcription complexes.

Acoustic Emission by Quartz Tuning Forks and Other Oscillating Structures in Cryogenic 4He Fluids  

NASA Astrophysics Data System (ADS)

We report on experimental investigations of acoustic emission by quartz tuning forks resonating at frequencies 32 kHz, 38 kHz, 77 kHz and 100 kHz immersed in cold gaseous 4He and its normal and superfluid liquid phases. Frequency dependence of the observed low-drive-linewidth at 350 mK together with the temperature and pressure dependences (1.3 K < T < 4.2 K, 0 < p < 25 bar) of the observed damping of the high frequency (77 and 100 kHz) resonators measured in normal liquid 4He and its superfluid phase provide strong and direct evidence of the importance of sound emission by these tuning forks. Three analytical models of acoustic emission by vibrating tuning forks are developed and compared with the experimental results. We also discuss the importance of sound emission for experiments with the commonly used 32 kHz tuning forks as well as other oscillating structures—spheres, wires, grids and various micromachined sensors. We compare the relative importance of dissipative losses due to laminar viscous/ballistic drag and acoustic emission in liquid and superfluid 4He.

HERC2 Interacts with Claspin and regulates DNA origin firing and replication fork progression.  

PubMed

DNA replication, recombination, and repair are highly interconnected processes the disruption of which must be coordinated in cancer. HERC2, a large HECT protein required for homologous recombination repair, is an E3 ubiquitin ligase that targets breast cancer suppressor BRCA1 for degradation. Here, we show that HERC2 is a component of the DNA replication fork complex that plays a critical role in DNA elongation and origin firing. In the presence of BRCA1, endogenous HERC2 interacts with Claspin, a protein essential for G(2)-M checkpoint activation and replication fork stability. Claspin depletion slowed S-phase progression and additional HERC2 depletion reduced the effect of Claspin depletion. In addition, HERC2 interacts with replication fork complex proteins. Depletion of HERC2 alleviated the slow replication fork progression in Claspin-deficient cells, suppressed enhanced origin firing, and led to a decrease in MCM2 phosphorylation. In a HERC2-dependent manner, treatment of cells with replication inhibitor aphidicolin enhanced MCM2 phosphorylation. Taken together, our results suggest that HERC2 regulates DNA replication progression and origin firing by facilitating MCM2 phosphorylation. These findings establish HERC2 as a critical function in DNA repair, checkpoint activation, and DNA replication. PMID:21775519

Replication Fork Velocities at Adjacent Replication Origins Are Coordinately Modified during DNA Replication in Human Cells  

PubMed Central

The spatial organization of replicons into clusters is believed to be of critical importance for genome duplication in higher eukaryotes, but its functional organization still remains to be fully clarified. The coordinated activation of origins is insufficient on its own to account for a timely completion of genome duplication when interorigin distances vary significantly and fork velocities are constant. Mechanisms coordinating origin distribution with fork progression are still poorly elucidated, because of technical difficulties of visualizing the process. Taking advantage of a single molecule approach, we delineated and compared the DNA replication kinetics at the genome level in human normal primary and malignant cells. Our results show that replication forks moving from one origin, as well as from neighboring origins, tend to exhibit the same velocity, although the plasticity of the replication program allows for their adaptation to variable interorigin distances. We also found that forks that emanated from closely spaced origins tended to move slower than those associated with long replicons. Taken together, our results indicate a functional role for origin clustering in the dynamic regulation of genome duplication.

A rapid and efficient method to purify proteins at replication forks under native conditions.  

PubMed

Tools for studying replication fork dynamics are critical for dissecting the mechanisms of DNA replication, DNA repair, histone deposition, and epigenetic memory. Isolation of protein on nascent DNA (iPOND) is an elegant method for purifying replication fork proteins. Here, we present accelerated native iPOND (aniPOND), a simplification of the iPOND procedure with improved protein yield. Cell membrane lysis and nuclei harvesting are combined in one step to reduce washes and minimize sample loss. A mild nuclei lysis protocol is then used to better preserve DNA-protein complexes. aniPOND is faster than iPOND, avoids formaldehyde cross-linking, and improves protein yield 5- and 20-fold for the CAF1-complex or PCNA respectively. Moreover, using aniPOND, but not iPOND, we could detect the polycomb repressive complex 2 (PRC2) components SUZ12, EZH2, and RBBP4 at replication forks. This faster, higher-yield method will facilitate MS analysis of replication fork complexes. PMID:24107252

Dissolved-Solids Load in Henrys Fork Upstream from the Confluence with Antelope Wash, Wyoming, Water Years 1970-2009  

USGS Publications Warehouse

Annual dissolved-solids load at the mouth of Henrys Fork was estimated by using data from U.S. Geological Survey streamflow-gaging station 09229500, Henrys Fork near Manila, Utah. The annual dissolved-solids load for water years 1970-2009 ranged from 18,300 tons in 1977 to 123,300 tons in 1983. Annual streamflows for this period ranged from 14,100 acre-feet in 1977 to 197,500 acre-feet in 1983. The 25-percent trimmed mean dissolved-solids load for water years 1970-2009 was 44,300 tons per year at Henrys Fork near Manila, Utah. Previous simulations using a SPAtially Referenced Regression On Watershed attributes (SPARROW) model for dissolved solids specific to water year 1991 conditions in the Upper Colorado River Basin predicted an annual dissolved-solids load of 25,000 tons for the Henrys Fork Basin upstream from Antelope Wash. On the basis of computed dissolved-solids load data from Henrys Fork near Manila, Utah, together with estimated annual dissolved-solids load from Antelope Wash and Peoples Canal, this prediction was adjusted to 37,200 tons. As determined by simulations with the Upper Colorado River Basin SPARROW model, approximately 56 percent (14,000 tons per year) of the dissolved-solids load at Henrys Fork upstream from Antelope Wash is associated with the 21,500 acres of irrigated agricultural lands in the upper Henrys Fork Basin.

Open Doorway to Truth: Legacy of the Minnesota Tobacco Trial

More than a decade has passed since the conclusion of the Minnesota tobacco trial and the signing of the Master Settlement Agreement (MSA) by 46 US State Attorneys General and the US tobacco industry. The Minnesota settlement exposed the tobacco industry's long history of deceptive marketing, advertising, and research and ultimately forced the industry to change its business practices. The provisions for public document disclosure that were included in the Minnesota settlement and the MSA have resulted in the release of approximately 70 million pages of documents and nearly 20,000 other media materials. No comparable dynamic, voluminous, and contemporaneous document archive exists. Only a few single events in the history of public health have had as dramatic an effect on tobacco control as the public release of the tobacco industry's previously secret internal documents. This review highlights the genesis of the release of these documents, the history of the document depositories created by the Minnesota settlement, the scientific and policy output based on the documents, and the use of the documents in furthering global public health strategies.
