Acoustic Telemetry Evaluation of Juvenile Salmonid Passage and Survival at John Day Dam with Emphasis on the Prototype Surface Flow Outlet, 2008

DOE Office of Scientific and Technical Information (OSTI.GOV)

Weiland, Mark A.; Ploskey, Gene R.; Hughes, James S.

The main purpose of the study was to evaluate the performance of Top Spill Weirs installed at two spillbays at John Day Dam and evaluate the effectiveness of these surface flow outlets at attracting juvenile salmon away from the powerhouse and reducing turbine passage. The Juvenile Salmonid Acoustic Telemetry System (JSATS) was used to estimate survival of juvenile salmonids passing the dam and also for calculating performance metrics used to evaluate the efficiency and effectiveness of the dam at passing juvenile salmonids.

Gardner-Thorpe, Christopher

2013-01-01

John Bell, brother-surgeon of Charles Bell, was, like Charles, an outstanding surgeon and a good artist. John was one of the few who illustrated his work with their own drawings in the days before audiovisual aids were available and without the benefit of reliable drawing aids, photography and computer-aided design. Charles, on the other hand, was the better artist and illustrated much of the normal anatomy of the nervous system. Each brother undertook extensive surgery of men who had been wounded in war; John Bell left us his engravings from the textbooks, more numerous perhaps than Charles, but Charles left us a series of oil paintings and watercolours in addition to the illustrations in his textbooks. © 2013 Elsevier B.V.

Wolthers, Ole D

2016-02-01

During recent years, extra-fine particle inhaled corticosteroids with a median aerodynamic diameter ≤2 μm have been introduced in the treatment of asthma. The aim of this paper was to review pharmacokinetics and systemic activity of extra-fine particle hydroalkane pressurized metered dose inhaled (pMDI) ciclesonide and beclomethasone dipropionate in children. A literature review was performed. Systemic bioavailability of oral and pulmonary deposition of extra-fine ciclesonide and beclomethasone dipropionate was 52% and 82%, the half-life in serum 3.2 and 1.5 h and first-pass hepatic metabolism >99% and 60%, respectively. Secondary analyses of urine cortisol/creatinine excretion found no effects of ciclesonide pMDI between 40 and 320 μg/day or of beclomethasone dipropionate pMDI between 80 and 400 μg/day. Ciclesonide pMDI 40, 80 and 160 μg/day caused no effects on short-term lower leg growth rate as assessed by knemometry. Ciclesonide 320 μg/day was associated with a numerically short-term growth suppression equivalent to 30% which was similar to 25% and 36% suppression caused by beclomethasone dipropionate HFA and CFC 200 μg/day, respectively. Consistent with the differences in key pharmacokinetic features, beclomethasone dipropionate is associated with a systemic activity detected by knemometry at a lower dose than ciclesonide. Whether that correlates with a clinically important difference remains to be explored. Assessments of systemic activity of beclomethasone dipropionate <200 μg/day and of ciclesonide >180 μg/day as well as head-to-head comparisons are warranted. Preferably, such studies should apply the sensitive method of knemometry. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

System-Wide Significance of Predation on Juvenile Salmonids in Columbia and Snake River Reservoirs : Annual Report 1992.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Petersen, James H.; Poe, Thomas P.

1993-12-01

Northern squawfish (Ptychocheilus oregonensis) predation on juvenile salmonids was characterized during 1992 at ten locations in the Columbia River below Bonneville Dam and at three locations in John Day Reservoir. During the spring and summer, 1,487 northern squawfish were collected in the lower Columbia River and 202 squawfish were sampled in John Day Reservoir. Gut content data, predator weight, and water temperature were used to compute a consumption index (CI) for northern squawfish, and overall diet was also described. In the Columbia River below Bonneville Dam, northern squawfish diet was primarily fish (spring 69%; summer 53%), most of which weremore » salmonids. Salmonids were also the primary diet component in the Bonneville Dam tailrace, John Day Dam forebay, and the McNary Dam tailrace. Crustaceans were the dominant diet item at the John Day mid-reservoir location, although sample sizes were small. About half of the non-salmonid preyfish were sculpins. The consumption index (CI) of northern squawfish was generally higher during summer than during spring. The highest CI`s were observed during summer in the tailrace boat restricted zones of Bonneville Dam (CI = 7.8) and McNary Dam (CI = 4.6). At locations below Bonneville Dam, CI`s were relatively low near Covert`s Landing and Rooster Rock, higher at four locations between Blue Lake and St. Helens, and low again at three downriver sites (Kalama, Ranier, and Jones Beach). Northern squawfish catches and CI`s were noticeably higher throughout the lower Columbia compared to mid-reservoir sites further upriver sampled during 1990--92. Predation may be especially intense in the free-flowing section of the Columbia River below Bonneville Dam. Smallmouth bass (Micropterus dolomieui; N = 198) ate mostly fish -- 25% salmonids, 29% sculpins, and 46% other fish. Highest catches of smallmouth bass were in the John Day Dam forebay.« less

2014-02-01

People with dry skin (xerosis) are common in community pharmacies, but there is no consistent guidance for community pharmacists to evaluate and alleviate dry skin. Through evaluating any difference of the clinical scoring systems of EEMCO guidance between a dermatologist and pharmacists and the efficacy of moisturizers for the treatment of dry skin recommended by community pharmacists, we aim to validate a dry skin guidance through the help of community pharmacists. These results provide insight into how community pharmacists can help patients with dry skin. The clinical scoring systems of EEMCO guidance used in this study comprised analog scales, the overall dry skin score (ODS), and the specific symptom sum score (SRRC) system. All pictures of the dry skin scored by pharmacists were visually evaluated by a dermatologist. The efficacy of the moisturizers was determined by the difference of the scales on day 0 and on day 28. In this study, 387 patients with dry skin from 157 community pharmacies were evaluated by pharmacists. Visual scale with divisions, ODS and SRRC that were evaluated by pharmacists on day 0 and day 28 were moderately reliable by a dermatologist. All parameters of dry skin were significantly improved by the moisturizers which were recommended by community pharmacists on day 28. Visual scale, ODS and SRRC can be generally measured to evaluate dry skin in community pharmacies with moderate degree of reliability. This finding has possible applications for investigating the assessment of the community pharmacists on clinical scoring system of dry skin and moisturizers. © 2013 John Wiley & Sons A/S.

One of the Pacific Northwest's most notable outdoor recreation areas, the "John Day Country" in northeastern Oregon, is named after a native Virginian who was a member of the Astor expedition to the mouth of the Columbia River in 1812. There is little factual information about John Day except that he was born in Culpeper County, Virginia, about 1770. It is known also that in 1810 this tall pioneer "with an elastic step as if he trod on springs" joined John Jacob Astor's overland expedition under Wilson Price Hunt to establish a vast fur-gathering network in the Western States based on a major trading post at the mouth of the Columbia River.

Optimization of Concurrent Deployments of the Juvenile Salmon Acoustic Telemetry System and Other Hydroacoustic Equipment at John Day Dam

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ploskey, Gene R.; Hughes, James S.; Khan, Fenton

The purpose of this report is to document the results of the acoustic optimization study conducted at John Day Dam during January and February 2008. The goal of the study was to optimize performance of the Juvenile Salmon Acoustic Telemetry System (JSATS) by determining deployment and data acquisition methods to minimize electrical and acoustic interference from various other acoustic sampling devices. Thereby, this would allow concurrent sampling by active and passive acoustic methods during the formal evaluations of the prototype surface flow outlets at the dam during spring and summer outmigration seasons for juvenile salmonids. The objectives for the optimizationmore » study at John Day Dam were to: 1. Design and test prototypes and provide a total needs list of pipes and trolleys to deploy JSATS hydrophones on the forebay face of the powerhouse and spillway. 2. Assess the effect on mean percentage decoded of JSATS transmissions from tags arrayed in the forebay and detected on the hydrophones by comparing: turbine unit OFF vs. ON; spill bay OPEN vs. CLOSED; dual frequency identification sonar (DIDSON) and acoustic Doppler current profiler (ADCP) both OFF vs. ON at a spill bay; and, fixed-aspect hydroacoustic system OFF vs. ON at a turbine unit and a spill bay. 3. Determine the relationship between fixed-aspect hydroacoustic transmit level and mean percentage of JSATS transmissions decoded. The general approach was to use hydrophones to listen for transmissions from JSATS tags deployed in vertical arrays in a series perpendicular to the face of the dam. We used acoustic telemetry equipment manufactured by Technologic and Sonic Concepts. In addition, we assessed old and new JSATS signal detectors and decoders and two different types of hydrophone baffling. The optimization study consisted of a suite of off/on tests. The primary response variable was mean percentage of tag transmissions decoded. We found that there was no appreciable adverse effect on mean percentage decoded for JSATS transmitters from: turbine operations; spillway operations; DIDSON/ADCP acoustic energy; and PAS hydroacoustic systems at transmit level of -12 dB, although there was a significant impact at all higher transmit levels (-11 to -6 dB). The main conclusion from this optimization study is that valid JSATS telemetry data can be collected simultaneously with a DIDSON/ADCP and a PAS hydroacoustic system at transmit level -12 dB. Multiple evaluation tools should be considered to increase the robustness and thoroughness of future fish passage evaluations at John Day and other dams.« less

Changes in the systemic immune response are found in preeclampsia. This may be related to high extracellular adenosine triphosphate (ATP) levels. The question arose whether ATP could affect immune responses in pregnancy. Previously, we investigated whether ATP affected monocyte activation and subpopulations. Here, we investigated ATP-induced changes in other immune cell populations in pregnant rats, systemically and in the kidney, an affected organ in preeclampsia. Using flow cytometry or immunohistochemistry, blood and kidney leukocytes were studied in pregnant and non-pregnant rats at different intervals after ATP or saline infusion. Adenosine triphosphate (ATP) infusion induced increased peripheral blood non-classical monocytes and decreased T lymphocyte subsets in pregnant rats only, higher glomerular macrophage and T lymphocyte numbers in non-pregnant animals 1 day after infusion, and higher glomerular macrophage numbers in pregnant rats 6 days after infusion. Adenosine triphosphate (ATP) infusion in pregnant rats induced a pregnancy-specific inflammatory response. Increased ATP levels could potentially contribute to development of the inflammatory response of preeclampsia. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Ecology of an estuarine mysid shrimp in the Columbia River (USA)

USGS Publications Warehouse

Haskell, C.A.; Stanford, J.A.

2006-01-01

The estuarine mysid, Neomysis mercedis, has colonized John Day and other run-of-the-river Reservoirs of the Columbia River, over 400 km from the estuary. In John Day Reservoir N. mercedis numbers peaked (2 m-3) in August in areas near the dam in association with lower water velocity and softer bottom than at the upstream sampling sites. Neomysis broods were primarily released in late spring and early fall. Gut content analysis showed that Neomysis feeds mostly on cladoceran zooplankton and rotifers in John Day Reservoir. Diel vertical migration was documented, with daytime distribution restricted to the bottom and preferentially to the soft-textured sediments in the deepest areas. Common pelagic fishes in the reservoir, especially juvenile American shad (Alosa sapidissima) and chinook salmon (Oncorhynchus tshawytscha), are daytime zooplankton feeders that cannot prey on Neomysis owing to mysid diel vertical migration. Thus, Neomysis has become an important food web component in John Day Reservoir. We also collected N. mercedis further upstream in Lower Granite Reservoir, where another estuarine crustacean, Corophium salmonis, also is reported, underscoring the need to better understand the role of these estuarine invertebrates in the trophic ecology of the Columbia River.

Understanding drug interactions with St John's wort (Hypericum perforatum L.): impact of hyperforin content.

PubMed

Chrubasik-Hausmann, Sigrun; Vlachojannis, Julia; McLachlan, Andrew J

2018-02-07

The aim of this study was to review herb-drug interaction studies with St John's wort (Hypericum perforatum L.) with a focus on the hyperforin content of the extracts used in these studies. PUBMED was systematically searched to identify studies describing pharmacokinetic interactions involving St John's wort. Data on study design and the St John's wort extract or product were gathered to extract hyperforin content and daily dose used in interaction studies. This analysis demonstrates that significant herb-drug interactions (resulting in a substantial change in systemic exposure) with St John's wort products were associated with hyperforin daily dosage. Products that had a daily dose of <1 mg hyperforin were less likely to be associated with major interaction for drugs that were CYP3A4 or p-glycoprotein substrates. Although a risk of interactions cannot be excluded even for low-dose hyperforin St. John's wort extracts, the use of products that result in a dose of not more than 1 mg hyperforin per day is recommended to minimise the risk of interactions. This review highlights that the significance of herb-drug interactions with St John's wort is influenced by the nature of the herbal medicines product, particularly the hyperforin content. © 2018 Royal Pharmaceutical Society.

During severe sepsis, levels and activity of all coagulation proteins are reduced. Heparanase is implicated in angiogenesis and tumor progression. We previously demonstrated that heparanase also affected the hemostatic system. It forms a complex and increases the activity of the blood coagulation initiator tissue factor. To evaluate heparanase levels and procoagulant activity as predictors of sepsis severity. Twenty-one patients with non-trauma, non-surgical sepsis admitted to the intensive care unit and 35 controls were recruited. Plasma samples were drawn from the study participants on days 1 and 7 following admission. Heparanase levels and procoagulant activity on day 1 were significantly reduced in patients compared to controls (P < .0001, P < .0001, respectively). Day 1 heparanase procoagulant activity ≥350 ng/mL yielded a negative predictive value for severe sepsis of 89%. Additionally, heparanase procoagulant activity on day 7 correlated with the change in the APACHE score between days 1 and 7 (r = .66, P = .007). Heparanase procoagulant activity decreases during sepsis and returns to normal levels as soon as the patient recovers. Hence, it can be potentially used to predict the risk of severe sepsis. These findings need to be further explored in large-scale studies. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Escapement and Productivity of Spring Chinook and Summer Steelhead in the John Day River Basin, Technical Report 2004-2005.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wilson, Wayne

The objectives are: (1) Estimate number and distribution of spring Chinook salmon Oncorhynchus tshawytscha redds and spawners in the John Day River subbasin; and (2) Estimate smolt-to-adult survival rates (SAR) and out-migrant abundance for spring Chinook and summer steelhead O. mykiss and life history characteristics of summer steelhead. Spawning ground surveys for spring (stream-type) Chinook salmon were conducted in four main spawning areas (Mainstem, Middle Fork, North Fork, and Granite Creek System) and seven minor spawning areas (South Fork, Camas Creek, Desolation Creek, Trail Creek, Deardorff Creek, Clear Creek, and Big Creek) in the John Day River basin during Augustmore » and September of 2005. Census surveys included 298.2 river kilometers (88.2 rkm within index, 192.4 rkm additional within census, and 17.6 rkm within random survey areas) of spawning habitat. We observed 902 redds and 701 carcasses including 227 redds in the Mainstem, 178 redds in the Middle Fork, 420 redds in the North Fork, 62 redds in the Granite Creek System, and 15 redds in Desolation Creek. Age composition of carcasses sampled for the entire basin was 1.6% age 3, 91.2% age 4, and 7.1% age 5. The sex ratio was 57.4% female and 42.6% male. Significantly more females than males were observed in the Granite Creek System. During 2005, 82.3% of female carcasses sampled had released all of their eggs. Significantly more pre-spawn mortalities were observed in Granite Creek. Nine (1.3%) of 701 carcasses were of hatchery origin. Of 298 carcasses examined, 4.0% were positive for the presence of lesions. A significantly higher incidence of gill lesions was found in the Granite Creek System when compared to the rest of the basin. Of 114 kidney samples tested, two (1.8%) had clinical BKD levels. Both infected fish were age-4 females in the Middle Fork. All samples tested for IHNV were negative. To estimate spring Chinook and summer steelhead smolt-to-adult survival (SAR) we PIT tagged 5,138 juvenile Chinook and 4,913 steelhead during the spring of 2005. We estimated that 130,144 (95% CL's 97,133-168,409) Chinook emigrated from the upper John Day subbasin past our seining area in the Mainstem John Day River (river kilometers 274-296) between February 4 and June 16, 2005. We also estimated that 32,601 (95% CL's 29,651 and 36,264) Chinook and 47,921 (95% CL's 35,025 and 67,366) steelhead migrated past our Mainstem rotary screw trap at river kilometer (rkm) 326 between October 4, 2004 and July 6, 2005. We estimated that 20,193 (95% CL's 17,699 and 22,983) Chinook and 28,980 (95% CL's 19,914 and 43,705) steelhead migrated past our Middle Fork trap (rkm 24) between October 6, 2004 and June 17, 2005. Seventy three percent of PIT tagged steelhead migrants were age-2 fish, 13.8% were age-3, 12.7% were age-2, and 0.3% were age 4. Spring Chinook SAR for the 2002 brood year was estimated at 2.5% (100 returns of 4,000 PIT tagged smolts). Preliminary steelhead SAR (excluding 2-ocean fish) for the 2004 tagging year was estimated at 1.61% (60 returns of 3,732 PIT-tagged migrants).« less

Surgical wounds in diabetic patients still remain a problem till the present day. As a common plant found around the world, Hypericum perforatum L. (Hypericaceae) is traditionally prepared as an oily extract and used as a folk remedy for various diseases such as wounds, burns, cuts, etc. This study aims to evaluate the effect of St. John's wort (Hypericum perforatum) on problematic wounds while comparing oral and topical applications. Incisional and excisional wound models were made on the dorsal regions of 54 diabetic Spraque-Dawley rats. The rats were divided into the following six groups (n = 9): Group 1: control, Group 2: diabetic, Group 3: diabetic oral Hypericum perforatum, Group 4: diabetic topical Hypericum perforatum, Group 5: diabetic oral olive oil, and Group 6: diabetic topical olive oil. Groups 3 and 4 had significantly higher tensile strength, tissue hydroxyproline concentration, and collagen density compared with Group 2. Inflammatory cell density and collagen density on day 3 were significantly higher in Groups 3 and 6 compared with Group 2. On day 21, Groups 3 and 6 had significantly higher fibroblastic activity compared with Group 2. This study has proved that oral St. John's wort has more positive effects on problematic wounds compared with topical St. John's wort and olive oil, which is a vehicle. Hypericum perforatum results with faster inflammatory response and better healing. These results could be an addition to literature about the clinical usage of Hypericum perforatum on diabetic wounds.

Iron represents an essential, but potentially harmful micronutrient, whose regulation has been associated with poor outcome in liver disease. Its homeostasis is tightly linked to oxidative stress, bacterial infections and systemic inflammation. To study the prognostic short-term significance of iron parameters in a cohort study of patients with decompensation of cirrhosis at risk of acute-on-chronic liver failure (ACLF). Ferritin, transferrin, iron, transferrin saturation (TSAT) and hepcidin were determined in sera from 292 German patients hospitalized for decompensation of cirrhosis with ascites, of which 78 (27%) had ACLF. Short-term mortality was prospectively assessed 30 and 90 days after inclusion. Transferrin concentrations were significantly lower, whereas ferritin and TSAT were higher in patients with ACLF compared to patients without ACLF (P≤.006). Transferrin, TSAT and ferritin differentially correlated with the severity of organ failure, active alcoholism and surrogates of systemic inflammation and macrophage activation. As compared with survivors, 30-day non-survivors displayed lower serum transferrin (P=.0003) and higher TSAT (P=.003), whereas 90-day non-survivors presented with higher ferritin (P=.03) and lower transferrin (P=.02). Lower transferrin (continuous or dichotomized at 87 mg/dL) and consecutively higher TSAT (continuous or dichotomized >41%) indicated increased mortality within 30 days and remained significant after adjustment for organ failure and inflammation in multivariate regression models and across subgroups of patients. Among the investigated indicators of iron metabolism, serum transferrin concentration was the best indicator of organ failure and an independent predictor of short-term mortality at 30 days. © 2016 John Wiley & Sons A/S.

In Part 1 of this paper, we presented the engineering design and instrumentation of the Juvenile Salmon Acoustic Telemetry System (JSATS) cabled system, a nonproprietary sensing technology developed by the U.S. Army Corps of Engineers, Portland District (Oregon, USA) to meet the needs for monitoring the survival of juvenile salmonids through the hydroelectric facilities within the Federal Columbia River Power System. Here in Part 2, we describe how the JSATS cabled system was employed as a reference sensor network for detecting and tracking juvenile salmon. Time-of-arrival data for valid detections on four hydrophones were used to solve for the three-dimensional (3D) position of fish surgically implanted with JSATS acoustic transmitters. Validation tests demonstrated high accuracy of 3D tracking up to 100 m upstream from the John Day Dam spillway. The along-dam component, used for assigning the route of fish passage, had the highest accuracy; the median errors ranged from 0.02 to 0.22 m, and root mean square errors ranged from 0.07 to 0.56 m at distances up to 100 m. For the 2008 case study at John Day Dam, the range for 3D tracking was more than 100 m upstream of the dam face where hydrophones were deployed, and detection and tracking probabilities of fish tagged with JSATS acoustic transmitters were higher than 98%. JSATS cabled systems have been successfully deployed on several major dams to acquire information for salmon protection and for development of more “fish-friendly” hydroelectric facilities.

Impact of systemic lupus erythematosus (SLE) on fertility may be negative, and ovarian function can be also reduced by autoimmune oophoritis. In this article, we evaluated the ovarian reserve of pre-menopausal women firstly diagnosed with systemic lupus erythematosus (SLE). This was a prospective controlled study which included twenty women with SLE and twenty healthy women as controls in the reproductive age. Basal levels of FSH, estradiol (E2), and LH on cycle day 3 were measured. All participants underwent transvaginal ultrasonographic examination on the third day of their menstrual periods for the determination of ovarian volume (OV) and total antral follicle count (AFC). A significant difference in FSH, LH, and E2 levels was observed between women with SLE and healthy controls. There was a statistically significant reduction in total AFC and OV in SLE group. Age was associated negatively with AFC, whereas positively with FSH and LH. Menstrual irregularity was significantly higher in SLE patients than control. AFC was the most reliable test to show the menstrual irregularity and negatively correlated each other in women with SLE. In this preliminary study, the first in SLE patients, we illustrated that women with SLE had lower ovarian reserves and higher menstrual irregularity compared with healthy controls according to hormonal and ultrasonographical evaluation. © 2014 John Wiley & Sons A/S.

It is recognized that orthodontic force (OF) has an aggravating effect on the progression of destructive periodontitis if periodontitis have not been well controlled. However, the underlying mechanism is not completely clear. This study was to investigate the effect of antibiotic administration on OF-aggravated, ligature-induced experimental periodontitis in mice. C57BL/6 mice (male, 8 wk old) were divided into three groups (n = 8). Silk ligatures (SL) were tied around the maxillary right (group 1) or both (groups 2 and 3) first molars on day 0, removed on day 8 and systemic antibiotics was administered through drinking water (group 3) since day 8. OF was applied on the maxillary right first molars since day 13 (groups 2 and 3). All mice were killed on day 20. Total oral bacteria load was significantly higher in group 2 when compared to group 1 on day 20, whereas such count was greatly reduced in group 3 when antibiotics were administered. Periodontal bone loss was significantly increased on SL side vs. control side in group 1. Periodontal bone loss was significantly increased on OF + SL side vs. SL side in group 2 (p < 0.05) but not in group 3 when systemic antibiotics were administered. Gingival mRNA and protein expressions of receptor activator of nuclear factor kappa-B ligand/osteoprotegerin were significantly increased on OF + SL side vs. SL side in group 2 (p < 0.01) but not in group 3. However, comparable levels of tartrate-resistant acid phosphatase-positive cell formation within periodontal space and tooth movement were observed on OF + SL side in groups 2 and 3. Our results suggest that reduction of oral bacterial load by antibiotic administration alleviate orthodontic force-aggravated periodontitis bone loss. © 2017 John Wiley & Sons A/S.

2015-11-01

To determine whether lacosamide prolongs the corrected QT interval (QTc). In this randomized, double-blind, positive- and placebo-controlled, parallel-design trial, healthy volunteers were randomized to lacosamide 400 mg/day (maximum-recommended daily dose, 6 days), lacosamide 800 mg/day (supratherapeutic dose, 6 days), placebo (6 days), or moxifloxacin 400 mg/day (3 days). Variables included maximum time-matched change from baseline in QT interval individually corrected for heart rate ([HR] QTcI), other ECG parameters, pharmacokinetics (PK), and safety/tolerability. The QTcI mean maximum difference from placebo was -4.3 ms and -6.3 ms for lacosamide 400 and 800 mg/day; upper limits of the 2-sided 90% confidence interval were below the 10 ms non-inferiority margin (-0.5 and -2.5 ms, respectively). Placebo-corrected QTcI for moxifloxacin was +10.4 ms (lower 90% confidence bound >0 [6.6 ms]), which established assay sensitivity for this trial. As lacosamide did not increase QTcI, the trial is considered a negative QTc trial. There was no dose-related or clinically relevant effect on QRS duration. HR increased from baseline by ~5 bpm with lacosamide 800 mg/day versus placebo. Placebo-subtracted mean increases in PR interval at tmax were 7.3 ms (400 mg/day) and 11.9 ms (800 mg/day). There were no findings of second-degree or higher atrioventricular block. Adverse events (AEs) were dose related and most commonly involved the nervous and gastrointestinal systems. Lacosamide (≤ 800 mg/day) did not prolong the QTc interval. Lacosamide caused a small, dose-related increase in mean PR interval that was not associated with AEs. Cardiac, overall safety, and PK profiles for lacosamide in healthy volunteers were consistent with those observed in patients with partial-onset seizures. © 2015 John Wiley & Sons A/S.

Antiinflammatory and immunomodulatory benefit of green tea (Camellia sinensis) in autoimmune disease has been proven in recent studies. The objective of this study was to assess the effects of green tea on disease activity and quality of life in systemic lupus erythematosus patients. A randomized controlled trial on subjects with lupus was conducted, and 68 patients in the age range of 39.1 ± 10.3 years and body mass index of 25.7 ± 5.21 kg/m 2 completed the 12-week study. Patients were randomly divided into two groups of intervention (1000 mg green tea extract, two capsules/day) and control (1000 mg of starch, two capsules/day). Main outcome measure, systemic lupus erythematosus disease activity, was assessed by the systemic lupus erythematosus disease activity index at the first and after 3 months of intervention. In addition, patient's quality of life was evaluated by short form of quality-of-life questionnaire at baseline and after 3 months. Green tea extract supplementation significantly reduced disease activity in lupus patients (p < 0.004); in addition, it significantly increased the vitality (p < 0.006) and general health (p < 0.01). This study showed that daily consumption of green tea extracts for 12 weeks improves the systemic lupus erythematosus disease activity as well as some aspects of quality of life.

The aims were (1) to evaluate the modified version of the Intensive Care Unit Information Need Questionnaire for the broader hospital setting, and (2) to describe the differences in respondents' managerial activities and information needs according to the position held by the respondent and the type of hospital unit. Information systems do not support managerial decision-making sufficiently and information needed in the day-to-day operations management in hospital units is unknown. An existing questionnaire was modified and evaluated. Shift leaders, that is, the nurses and physicians responsible for the day-to-day operations management in hospital units were reached using purposive sampling (n = 258). The questionnaire ascertained the importance of information. Cronbach's α ranged from .85-.96 for the subscales. Item - total correlations showed good explanatory power. Managerial activities and information needs differed between respondents in different positions, although all shared about one-third of important information needs. The response rate was 26% (n = 67). The validity and reliability of the questionnaire were good. Attention should be paid to the positions of shift leaders when developing information systems. The questionnaire can be used to determine important information when developing information systems to support day-to-day operations management in hospitals. © 2018 John Wiley & Sons Ltd.

On this fifth day of the STS-79 mission, the flight crew, Cmdr. William F. Readdy, Pilot Terrence W. Wilcutt, Mission Specialists, Thomas D. Akers, Shannon Lucid, Jay Apt, and Carl E. Walz, in the first full day of joint Shuttle/Mir operations begin in with the transfer of a biotechnology investigation and logistical supplies from Atlantis to Mir. The Biotechnology System, an investigation that will study the long-term development of cartilage cells in microgravity, was transported to Mir early this morning. During his planned four-month stay on Mir, John Blaha will take weekly samples of the culture which may provide researchers with information on engineering cartilage cells for possible use in transplantation. They also took time out of their schedules to talk with Good Morning America's Elizabeth Vargas in a brief interview. Prior to beginning the day's transfer activities, all nine astronauts and cosmonauts participated in a joint planning session to outline the day's schedule.

Endovascular surgery benefits patients because of its superior short convalescence and lack of damage to healthy tissue. However, such advantages require the operator to be equipped with dexterous skills for catheter manipulation without resulting in collateral damage. To achieve this goal, a training system is in high demand. A training system integrating a VR simulator and a haptic device has been developed within this context. The VR simulator is capable of providing visual cues which assist the novice for safe catheterization. In addition, the haptic device cooperates with VR simulator to apply sensations at the same time. The training system was tested by non-medical subjects over a five days training session. The performance was evaluated in terms of safety criteria and task completion time. The results demonstrate that operation safety is improved by 15.94% and task completion time is cut by 18.80 s maximum. Moreover, according to subjects' reflections, they are more confident in operation. The proposed training system constructs a comprehensive training environment that combines visualization and force sensation. Copyright © 2016 John Wiley & Sons, Ltd.

Mapping the Riverscape of the Middle Fork John Day River with Structure-from-Motion

NASA Astrophysics Data System (ADS)

Dietrich, J. T.

2014-12-01

Aerial photography has proven an efficient method to collect a wide range of continuous variables for large sections of rivers. These data include variables such as the planimetric shape, low-flow and bank-full widths, bathymetry, and sediment sizes. Mapping these variables in a continuous manner allows us to explore the heterogeneity of the river and build a more complete picture of the holistic riverscape. To explore a low-cost option for aerial photography and riverscape mapping, I used the combination of a piloted helicopter and an off-the-shelf digital SLR camera to collect aerial imagery for a 32 km segment of the Middle Fork John Day River in eastern Oregon. This imagery was processed with Structure-from-Motion (SfM) photogrammetry to produce high-resolution 10 cm orthophotos and digital surface models that were used to extract riverscape variables. The Middle Fork John Day River is an important spawning river for anadromous Chinnook and Steelhead and has been the focus of widespread restoration and conservation activities in response to the legacies of extensive grazing and mining activity. By mapping the riverscape of the Middle Fork John Day, I explored downstream relationships between several geomorphic variables with hyperscale analysis. These riverscape data also provided an opportunity to make a continuous map of habitat suitability for migrating adult Chinook. Both the geomorphic and habitat suitability analysis provide an important assessment of the natural variation in the river and the impact of human modification, both positive and negative.

Surgical site infections (SSIs) may increase health care costs, but few studies have conducted an analysis from the perspective of hospital administrators. To determine the change in hospital profit due to SSIs. Retrospective study of data from January 1, 2007, to December 31, 2010. The study was performed at 4 of The Johns Hopkins Health System acute care hospitals in Maryland: Johns Hopkins Bayview (560 beds); Howard County General Hospital (238 beds); The Johns Hopkins Hospital (946 beds); and Suburban Hospital (229 beds). Eligible patients for the study included those patients admitted to the 4 hospitals between January 1, 2007, and December 31, 2010, with complete data and the correct International Classification of Diseases, Ninth Revision code, as determined by the infection preventionist. Infection preventionists performed complete medical record review using National Healthcare Safety Network definitions to identify SSIs. Patients were stratified using the All Patient Refined Diagnosis Related Groups to estimate the change in hospital profit due to SSIs. Surgical site infections. The outcomes of the study were the difference in daily total charges, length of stay (LOS), 30-day readmission rate, and profit for patients with an SSI when compared with patients without an SSI. The hypothesis, formulated prior to data collection, that patients with an SSI have higher daily total costs, a longer LOS, and higher 30-day readmission rates than patients without an SSI, was tested using a nonpaired Mann-Whitney U test, an analysis of covariance, and a Pearson χ2 test. Hospital charges were used as a proxy for hospital cost. RESULTS The daily total charges, mean LOS, and 30-day readmission rate for patients with an SSI compared with patients without an SSI were $7493 vs $7924 (P = .99); 10.56 days vs 5.64 days (P < .001); and 51.94 vs 8.19 readmissions per 100 procedures (P < .001). The change in profit due SSIs was $2 268 589. The data suggest that hospitals have a financial incentive to reduce SSIs, but hospitals should expect to see an increase in both cost and revenue when SSIs are reduced.

Footage of the eighth day of STS-109 is shown during which Mission Specialists John Grunsfeld and Rick Linnehan service the Hubble Space Telescope (HST). A broad overview of the Columbia Orbiter mission is presented. On the fifth extravehicular activity (EVA) of the mission, Grunsfeld and Linnehan installed a new cryogenic cooling system and radiator on HST for NICMOS (Near Infrared Camera and Multi-Object Spectrometer) which had not been previously operational due to the failure of an earlier cooling system. Linnehan and Grunsfeld are both shown on the end of the Orbiter's robot arm, the Remote Manipulator System, which was controlled by Commander Scott Altman. Following the completion of their spacewalks, the two Mission Specialists make statements which include thanking the numerous support personnel. Linnehan answers questions on the differences between training simulation at facilities such as the Neutral Buoyancy Lab (NBL) and his actual experiences in space.

Richman, Barbara T.

‘I want the journal to acquire a reputation for very rapid, fair, and accurate reviewing,’ asserted John F. Dewey, editor-in-chief of AGU's newest journal, Tectonics. Dewey said that he will rule the bimonthly, which will begin publication in February, ‘with a bit of a rod of iron’ to ensure that Tectonics is ‘where only original and important papers are published.’‘I'm going to be very strict with reviewers,’ Dewey explained in his quick British clip. ‘If the review does not come back to me within 10 days to 2 weeks, I'll review the paper myself. I'm also going to have a system whereby, if a paper needs major surgery after being refereed, it will be rejected. Papers will have to be in virtually publishable condition before they are first submitted,’ he said.

Brain architecture: a design for natural computation.

Fifty years ago, John von Neumann compared the architecture of the brain with that of the computers he invented and which are still in use today. In those days, the organization of computers was based on concepts of brain organization. Here, we give an update on current results on the global organization of neural systems. For neural systems, we outline how the spatial and topological architecture of neuronal and cortical networks facilitates robustness against failures, fast processing and balanced network activation. Finally, we discuss mechanisms of self-organization for such architectures. After all, the organization of the brain might again inspire computer architecture.

St. John's wort extract is widely used and advertised as a "natural antidepressant" lacking autonomic side effects. This randomized, double-blind, placebo-controlled study compared the effects of St. John's wort extract on autonomic responses of blood vessels and sweat glands with those of amitriptyline and placebo. A randomized, double-blind, crossover study was performed in healthy male volunteers aged 22 to 31 years (25 +/- 3 years; mean +/- SD) years. Subjects orally received capsules with 255 to 285 mg St. John's wort extract (900 microg hypericin content), 25 mg amitriptyline, and placebo 3 times daily for periods of 14 days each with at least 14 days between. Vasoconstrictory response of cutaneous blood flow (VR) and skin conductance response (SR) following a single deep inspiration were employed as parameters of autonomic function. St. John's wort extract had no effect on VR and SR. In contrast, SR was diminished and the dilation phase of VR was prolonged following multiple dosing with amitriptyline (P < 0.05). Decreased electrodermal reactivity observed with amitriptyline reflects inhibition of acetylcholine at peripheral m3-cholinoreceptors, whereas prolongation of VR induced by the tricyclic drug may be due to sustained activation of central and/or peripheral sympathetic neurons.

Inactivity and more sedentary time predominate the daily activity level of many of today's children. In Denmark, certified sport after-school cares have been established in order to increase children's daily physical activity (PA) level. This cross-sectional study aimed to investigate the activity level among participants in certified sport after-school cares vs regular after-school cares. The study was carried out in 2011 in 10 after-school cares (5 sport/5 regular) throughout Denmark, whereof 475 children aged 5-11 years participated. PA level was assessed using Actigraph GT3X and GT3X+ activity monitors worn by the children for at least 8 consecutive days. Anthropometry and cardiorespiratory fitness were measured as well. A multivariate regression analysis was carried out to check for the differences in the PA level across the two care systems. However, there did not appear to be any differences in overall PA or in time-specific day parts (e.g., during after-school care). The activity levels were quite similar across after-school cares and were mutually high during time spent in the care facility. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Optimizing a multifunctional microsphere scaffold to improve neural precursor cell transplantation for traumatic brain injury repair.

2016-10-01

Tissue engineering using stem cells is widely used to repair damaged tissues in diverse biological systems; however, this approach has met with less success in regenerating the central nervous system (CNS). In this study we optimized and characterized the surface chemistry of chitosan-based scaffolds for CNS repair. To maintain radial glial cell (RGC) character of primitive neural precursors, fibronectin was adsorbed to chitosan. The chitosan was further modified by covalently linking heparin using genipin, which then served as a linker to immobilize fibroblast growth factor-2 (FGF-2), creating a multifunctional film. Fetal rat neural precursors plated onto this multifunctional film proliferated and remained multipotent for at least 3 days without providing soluble FGF-2. Moreover, they remained less mature and more highly proliferative than cells maintained on fibronectin-coated substrates in culture medium supplemented with soluble FGF-2. To create a vehicle for cell transplantation, a 3% chitosan solution was electrosprayed into a coagulation bath to generate microspheres (range 30-100 µm, mean 64 µm) that were subsequently modified. Radial glial cells seeded onto these multifunctional microspheres proliferated for at least 7 days in culture and the microspheres containing cells were small enough to be injected, using 23 Gauge Hamilton syringes, into the brains of adult rats that had previously sustained cortical contusion injuries. When analysed 3 days later, the transplanted RGCs were positive for the stem cell/progenitor marker Nestin. These results demonstrate that this multifunctional scaffold can be used as a cellular and growth factor delivery vehicle for the use in developing cell transplantation therapies for traumatic brain injuries.

Aspirin desensitization (AD) treatment at doses of up to 1300 mg/day improves outcomes in aspirin-exacerbated respiratory disease (AERD). The aim of this study was to investigate the efficacy of aspirin 300 mg/day in the treatment of patients with AERD. The study included 40 patients diagnosed in our clinic as AERD that were desensitized and treated with aspirin 300 mg/day between December 2005 and December 2012. Changes from the baseline status were analyzed at 1 year and at 3 years of follow-up. Of the 40 patients included, 24 (60%) were female and median (interquartile range [IQR]) age was 45 (40-51) years. Median (IQR) duration of AD was 31.5 (10.5-48.5) months. In total, 29 patients continued treatment for at least 1 year and 18 patients for at least 3 years. The annual rate of use of systemic corticosteroid regimens, episodes of sinusitis, and surgery was significantly lower both at 1 year (P = 0.002, P = 0.01, and P < 0.001, respectively) and at 3 years (P = 0.001, P = 0.03, and P = 0.002, respectively). Significant improvement was observed in the nasal congestion score (P = 0.01) and sense of smell score (P = 0.05) at 1 year and in the postnasal drainage score (P = 0.01) at 3 years. Daily treatment with aspirin 300 mg had beneficial effects in patients with AERD, especially for the control of upper airway disease. © 2013 John Wiley & Sons A/S.

Fossil Flora of the John Day Basin, Oregon

USGS Publications Warehouse

Knowlton, Frank Hall

1902-01-01

For a number of years I have been gradually accumulating material for a thorough revision of the Tertiary floras of the Pacific slope. Fossil plants are known to occur at numerous points within this area, and their study and identification has already furnished valuable data bearing on the geological history of the region, and when still further exploited it is confidently expected that they will afford more exact data for the use of geologists. This investigation is progressing satisfactorily, and at no distant day it is hoped to have it in form for final publication. From time to time various members of the United States Geological Survey, as well as others not connected with this organization, have sent in small collections of fossil plants for determination. These have been studied and reported upon as fully as the condition of the problem permitted, so that the determinations could be immediately available to geologists, but with the reservation that none of the questions could be fully settled until all known material had been studied and properly correlated. The rich fossil plant deposits in the John Day Basin, as set forth more fully in the historical account which follows, have been known for a period of nearly fifty years, but their study has been carried on in a more or less desultory manner. There has also been considerable confusion as to the horizons whence these plants came. As various species of plants described originally from the John Day region were detected in various other localities in Oregon, and in surrounding areas, as central Washington, western Idaho, and northern California, it became more than ever apparent that a thorough study of all material obtainable from this type area would be necessary before any definite or satisfactory conclusions could be reached. The immediate incentive for this revision was furnished by the receipt of a considerable collection of plants, made by Dr. John C. Merriam in 1900 while he was in charge of an expedition into this region made under the auspices of the University of California. When these plants were submitted to me for study, it was thought possible to present their description, together with a revision of our knowledge of the previously known forms, within a space sufficiently small to permit the publication of the matter as an appendix to a paper on the general geology of the area, then in preparation by Dr. Merriam. But it soon became apparent that this could not be adequately done within the space available, and a short preliminary report was prepared for and published by Dr. Merriam. The results of a complete restudy of all available fossil plant material from the John Day Basin are now presented. I wish to record my great indebtedness to Dr. Merriam, who not only accompanied me at a considerable personal sacrifice on a trip through the region in 1901, but placed unreservedly at my disposal all material bearing in any way on the problem then in the paleontological museum of the University of California. To Dr. Arthur Hollick I am indebted for the loan of all material from the John Day region belonging to Columbia University, and now deposited in the New York Botanical Garden at Bronx Park.

Sacksteder, Kurt (Compiler)

2003-01-01

The Seventh International Workshop on Microgravity Combustion and Chemically Reacting Systems was planned for June 3-6, 2003, in Cleveland, Ohio, near the NASA John H. Glenn Research Center at Lewis Field. The new name for the workshop is based on the decision to broaden our scope to encompass support for future space exploration through basic and applied research in reacting systems that in some cases may not look like combustion. The workshop has been lengthened to 4 days with focus sessions on spacecraft fire safety and exploration-related research. We believe that the microgravity combustion science community is almost uniquely positioned to make substantial contributions to this new effort.

Inexpensive, rapid, and reliable tests for detecting the presence and drug susceptibility of Mycobacterium tuberculosis complex (MTBC) are urgently needed to control the transmission of tuberculosis. In this study, we aimed to assess the accuracy and speed of the microscopic-observation drug susceptibility (MODS) assay in the identification of MTBC and detection of multidrug resistance. Sputum samples from patients suspected to have tuberculosis were simultaneously tested with MODS and conventional culture [Löwenstein-Jensen (LJ) culture, BACTEC MGIT™ 960 (MGIT) system], and drug susceptibility testing (MGIT system) methods. A total of 331 sputum samples were analyzed. Sensitivity and specificity of MODS assay for detection of MTBC strains were 96% and 98.8%, respectively. MODS assay detected multidrug resistant MTBC isolates with 92.3% sensitivity and 96.6% specificity. Median time to culture positivity was similar for MGIT (8 days) and MODS culture (8 days), but was significantly longer with LJ culture (20 days) (p < 0.0001 for both comparisons). Median time to availability of the susceptibility results was significantly (p < 0.0001) shorter with MODS assay (8 days) than MGIT system (20 days). In conclusion, MODS is an inexpensive and rapid test with good performance characteristics for direct diagnosis of tuberculosis and detection of multidrug resistance. © 2017 APMIS.

As many as 2.4 million adult American shad annually pass John Day Dam, Columbia River to spawn upriver, yet food web interactions of juvenile shad rearing in John Day Reservoir are unexplored. We collected zooplankton and conducted mid-water trawls in McNary (June-July) and John Day reservoirs (August-November) from 1994 through 1996 during the outmigration of subyearling American shad and Chinook salmon. Juvenile American shad were abundant and represented over 98% of the trawl catch in late summer. The five major taxa collected in zooplankton tows were Bosmina longirostris, Daphnia, cyclopoid cope-pods, rotifers, and calanoid copepods. We evaluated total crustacean zooplankton abundance and Daphnia biomass in relation to water temperature, flow, depth, diel period, and cross-sectional location using multiple regression. Differences in zooplankton abundance were largely due to differences in water temperature and flow. Spatial variation in total zooplankton abundance was observed in McNary Reservoir, but not in John Day Reservoir. Juvenile American shad generally fed on numerically abundant prey, despite being less preferred than larger bodied zooplankton. A decrease in cladoceran abundance and size in August coupled with large percentages of Daphnia in juvenile American shad stomachs indicated heavy planktivory. Smaller juvenile American shad primarily fed on Daphnia in August, but switched to more evasive copepods as the mean size of fish increased and Daphnia abundance declined. Because Daphnia are particularly important prey items for subyearling Chinook salmon in mainstem reservoirs in mid to late summer, alterations in the cladoceran food base is of concern for the management of outmigrating salmonids and other Columbia River fishes. ?? 2006 by the Northwest Scientific Association.

Water availability and flood hazards in the John Day Fossil Beds National Monument, Oregon

USGS Publications Warehouse

Frank, Frank J.; Oster, E.A.

1979-01-01

The rock formations of the John Day Fossil Beds National Monument area are aquifers that can be expected to yield less than 10 gallons of water per minute to wells. The most permeable of the geologic units is the alluvium that occurs at low elevations along the John Day River and most of the smaller streams. Wells in the alluvial deposits can be expected to yield adequate water supplies for recreational areas; also, wells completed in the underlying bedrock at depths ranging from 50 to 200 feet could yield as much as 10 gallons per minute. Pumping tests on two unused wells indicated yields of 8 gallons per minute and 2 gallons per minute. Nine of the ten springs measured in and near the monument area in late August of 1978 were flowing 0.2 to 30 gallons per minute. Only the Cant Ranch spring and the Johnny Kirk Spring near the Sheep Rock unit had flows exceeding 6 gallons per minute. Chemical analyses of selected constituents of the ground water indicated generally low concentrations of dissolved minerals. Although cloudbursts in the Painted Hills unit could generate a flood wave on the valley floors, flood danger can be reduced by locating recreational sites on high ground. The campground in Indian Canyon of the Clarno unit is vulnerable to cloudburst flooding. About 80 percent of the proposed campground on the John Day River in the Sheep Rock unit is above the estimated level of 1-percent chance flood (100-year flood) of the river. The 1-percent chance flood would extend about 120 feet from the riverbank into the upstream end of the campground. (USGS).

Continuous hydroponic wheat production using a recirculating system

1989-01-01

Continuous crop production, where plants of various ages are growing simultaneously in a single recirculating nutrient solution, is a possible alternative to batch production in a Controlled Ecological Life Support System. A study was conducted at John F. Kennedy Space Center where 8 trays (0.24 sq m per tray) of Triticum aestivum L. Yecora Rojo were grown simultaneously in a growth chamber at 23 C, 65 percent relative humidity, 1000 ppm CO2, continuous light, with a continuous flow, thin film nutrient delivery system. The same modified Hoagland nutrient solution was recirculated through the plant trays from an 80 L reservoir throughout the study. It was maintained by periodic addition of water and nutrients based on chemical analyses of the solution. The study was conducted for 216 days, during which 24 trays of wheat were consecutively planted (one every 9 days), 16 of which were grown to maturity and harvested. The remaining 8 trays were harvested on day 216. Grain yields averaged 520 g m(exp -2), and had an average edible biomass of 32 percent. Consecutive yields were unaffected by nutrient solution age. It was concluded that continual wheat production will work in this system over an extended period of time. Certain micronutrient deficiencies and toxicities posed problems and must be addressed in future continuous production systems.

Video coverage of Day 3 includes highlights of STS-114 during the approach and docking of Discovery with the International Space Station (ISS). The Return to Flight continues with space shuttle crew members (Commander Eileen Collins, Pilot James Kelly, Mission Specialists Soichi Noguchi, Stephen Robinson, Andrew Thomas, Wendy Lawrence, and Charles Camarda) seen in onboard activities on the fore and aft portions of the flight deck during the orbiter's approach. Camarda sends a greeting to his family, and Collins maneuvers Discovery as the ISS appears steadily closer in sequential still video from the centerline camera of the Orbiter Docking System. The approach includes video of Discovery from the ISS during the orbiter's Rendezvous Pitch Maneuver, giving the ISS a clear view of the thermal protection systems underneath the orbiter. Discovery docks with the Destiny Laboratory of the ISS, and the shuttle crew greets the Expedition 11 crew (Commander Sergei Krikalev and NASA ISS Science Officer and Flight Engineer John Phillips) of the ISS onboard the station. Finally, the Space Station Remote Manipulator System hands the Orbiter Boom Sensor System to its counterpart, the Shuttle Remote Manipulator System.

The potential capability of NTP is game changing for space exploration. A first generation NCPS could provide high thrust at a specific impulse above 900 s, roughly double that of state of the art chemical engines. Near-term NCPS systems would provide a foundation for the development of significantly more advanced, higher performance systems. John F. Kennedy made his historic special address to Congress on the importance of space on May 25, 1961, "First, I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth..." This was accomplished. John F. Kennedy also made a second request, "Secondly... accelerate development of the Rover nuclear rocket. This gives promise of some day providing a means for even more exciting and ambitious exploration of space, perhaps beyond the Moon, perhaps to the very end of the solar system itself." The investment in the Rover nuclear rocket program provided the foundation of technology that gives us assurance for greater performing rockets that are capable of taking us further into space. Combined with current technologies, the vision to go beyond the Moon and to the very end of the solar system can be realized with space nuclear propulsion and power.

Obituary: John W. Firor (1927-2007)

NASA Astrophysics Data System (ADS)

Gilman, Peter A.

2009-12-01

John W. Firor, a former Director of the High Altitude Observatory and the National Center for Atmospheric Research, and a founder of the Solar Physics Division of the American Astronomical Society, died of Alzheimer's disease in Pullman, Washington on November 5, 2007, he was 80. He was born in Athens Georgia on October 18, 1927, where his father was a professor of agricultural economics. John had an unusually diverse scientific career. His interest in physics and astrophysics began while serving in the army, during which time he was assigned to the Los Alamos National Laboratory, where he guarded highly radioactive materials (many have heard him describe how informal the protections were compared to later times). After his service he returned to college and graduated in physics from Georgia Tech in 1949. He received his Ph.D. from the University of Chicago in 1954, writing his thesis on cosmic rays under John Simpson. John Firor would later remark that: "If you needed cosmic rays to actually do anything, you are sunk." That thought, partly in jest, may help explain his motivation for moving to so many new scientific and management pursuits. John moved from cosmic ray physics to radio astronomy (particularly of the Sun) when he began work at the Carnegie Institution of Washington's Department of Terrestrial Magnetism, where he remained until 1961. During this time, he met Walter Orr Roberts, then the Director of the High Altitude Observatory (HAO) in Boulder, Colorado. HAO was then affiliated with the University of Colorado. In 1959, a movement began to upgrade the atmospheric sciences in the United States by establishing a National Center, where the largest, most important atmospheric research problems could be addressed. Roberts became the first Director of NCAR, as well as the first president of the University Corporation for Atmospheric Research (UCAR), the consortium of universities that was commissioned to manage and staff the new Center. HAO became a scientific division of NCAR (Roberts made it a requirement if he was to be NCAR Director). He chose John to be the new HAO Director. John was 33 then; his leadership potential was recognized very early. While Director of HAO, John presided over a very active scientific program that focused on non-equilibrium thermodynamics, radiative transfer, plasma physics, coronal spectroscopy, geomagnetism, physics of the Earth's upper atmosphere, and solar activity. Prominent scientists such as Jack Evans, Sydney Chapman, Gene Parker, Leo Goldberg and Donald Menzel visited to share their insights and enthusiasm with the HAO staff. John was also an active participant in HAO's well-known solar eclipse expeditions, traveling to New Guinea and to Lake Chad in Africa. Late in his tenure as HAO Director, he took the lead in helping to improve the involvement of the AAS in solar physics, and solar physicists in the AAS. Having led the AAS committee that planned its birth, he was the founding chair of the new Solar Physics Division. Much less importantly, he gave me a summer position in 1966 when I was joining the faculty at CU--that is when I first met John. In 1968, John became the Director of NCAR when Walter Roberts decided to split the directorship from the Presidency of UCAR. As NCAR Director, John had responsibility for a vastly broadened program compared to his HAO days. NCAR, the largest NSF supported research center, conducted research covering all of atmospheric sciences, as well as oceanography and solar-terrestrial physics. It also provided major observational and computational facilities to the atmospheric sciences community. John showed very quickly he understood and could guide all of it. I came to know John best during this period, because in 1971 he chose me to head the Advanced Study Program, which supported (and still supports) postdoctoral and graduate education. In that time, budgets were good, and NCAR was a relatively collegial, informal place. But in December 1973, that all changed suddenly. NCAR management was reviewed by an NSF-appointed Joint Evaluation Committee (JEC), whose report raised many questions. Walter Roberts resigned as UCAR President, and John had the task of working with the UCAR Board to make major changes. During this time, John asked me to put aside my ASP duties to assist him. Over the next 18 months, NCAR was restructured, several Division Directors replaced, a new, more rigorous scientific appointment system was developed, and a major budget cut was absorbed. John did all of this; in my view, it was heroic. Then the UCAR Board appointed a new UCAR President and NCAR Director, Francis Bretherton, and John became the NCAR Executive Director. John used to say that many people asked him how he felt about being 'demoted'--always gracious, he said he never saw it that way. In fact, he was mentoring Bretherton, who was very junior to John in experience, never having held a major management position. The Bretherton-Firor 'team' managed UCAR until 1980. Then a new UCAR and NCAR management was chosen, and John had to decide what to do next. He took a sabbatical and became more deeply involved in environmental issues. But this interest had been kindled much before. As early as 1970, he was writing and speaking about environmental questions while NCAR Director. When he returned to NCAR, he became the Director of the Advanced Study Program (ASP), what I had been a decade before. He served NCAR in that role until 1996. When he stepped down, he remarked that he had been a member of the NCAR Directors Committee for 34 years; a record that he judged should never be broken. While John was attentive to the needs of the post-docs and graduate students his program supported, ASP was a platform for him to pursue his environmental interests. He spoke and wrote clearly and influentially on environmental issues. He served on the Boards of several important environmental organizations and wrote two well received environmental books: "The Changing Atmosphere: A Global Challenge" (1990), and, with his wife Judith Jacobsen "The Crowded Greenhouse: Population, Climate Change and Creating a Sustainable World" (2002). After ASP, he continued his focus on environmental issues as a member of the Environmental and Societal Impacts group at NCAR. John retired from NCAR in 2005. John had many active pursuits beyond his professional work. He was an accomplished pilot, with licenses for flying single and multiengine aircraft, sailplanes, and balloons. He piloted a sailplane in at least one meteorological field program. He also was an avid river rafter. John faced the disease that took his life as he did all events in his life, with grace and dignity. He endured the loss of two spouses to cancer, Merle Jenkins Firor in 1979, and Judith Jacobsen in 2004. John is survived by his four children with his first wife, Daniel Firor of Seattle, Washington; Kay Firor of Cove, Oregon; James Firor of Hotchkiss, Colorado, and Susan Firor of Moscow, Idaho; a sister; a brother; and three grandchildren. His children and his many friends in Boulder and elsewhere gave him loving support during his days battling Alzheimer's. John used to define a 'southern gentleman' as a man dressed in white linen suit on a hot dusty summer day in a small Georgia town who could cross the street without breaking a sweat. John and his intellect and his management ability were like that; he could deal gracefully and successfully with almost anything that came his way. A man of great accomplishment, he rarely showed an ego to match. In the darkest days following the JEC Report, he almost single-handedly invented a new NCAR scientific appointment system. He chose the first cadre of 'senior scientists' to populate the top rank. There were about eighteen members in this group, but there was one name conspicuously absent - his own. This 'error' was quietly corrected by the UCAR Board.

Pediatric HSCT recipients are at high risk for CMV reactivation due to their immature immune system and therapy following transplantation. Reconstitution of CMV-specific T-cell immunity is associated with control and protection against CMV. The clinical utility of monitoring CMV-specific CMI to predict CMV viremia in pediatric HSCT patients using the Quantiferon-CMV (QIAGEN ® ) test was investigated prospectively. Thirty-seven pediatric allogeneic HSCT recipients were enrolled from 3/2010-6/2012. CMV viremia was detected via weekly real-time PCR. The Quantiferon-CMV test was conducted pretransplant, early after transplantation, 30, 90, 180, 270, and 360 days post-transplantation. The incidence of CMV viremia was 51% (19/37) with half of the episodes within ≤30 days post-transplant. Fifteen patients showed CMV-specific immunity (average of 82 days). The cumulative incidence of CMV reactivation in patients who developed CMV-specific immunity was lower than those who did not (15% vs 53%; P = .023). The ROC statistical analysis showed that the AUC was 0.725 in predicting viremia, for Quantiferon-CMV test. In this cohort, the Quantiferon-CMV assay was a valuable method for identifying pediatric HSCT patients at high risk for CMV viremia, suggesting potential clinical utility to individualize patient's management post-transplant. © 2018 John Wiley & Sons A/S.

Geologic Reconnaissance of the Antelope-Ashwood Area, North-Central Oregon: With Emphasis on the John Day Formation of Late Oligocene and Early Miocene Age

USGS Publications Warehouse

Peck, Dallas L.

1964-01-01

This report briefly describes the geology of an area of about 750 square miles in Jefferson, Wasco, Crook, and Wheeler Counties, Oregon. About 16,000 feet of strata that range in age from pre-Tertiary to Quaternary are exposed. These include the following units: pre-Tertiary slate, graywacke, conglomerate, and meta-andesite; Clarno Formation of Eocene age - lava flows, volcanic breccia, tuff, and tuffaceous mudstone, chiefly of andesitic composition; John Day Formation of late Oligocene and early Miocene age - pyroclastic rocks, flows, and domes, chiefly of rhyolitic composition; Columbia River Basalt of middle Miocene age - thick, columnar jointed flows of very fine grained dense dark-gray basalt; Dalles Formation of Pliocene age - bedded tuffaceous sandstone, siltstone, and conglomerate; basalt of Pliocene or Pleistocene age - lava flows of porous-textured olivine basalt; and Quaternary loess, landslide debris, and alluvium. Unconformities separate pre-Tertiary rocks and Clarno Formation, Clarno and John Day Formations, John Day Formation and Columbia River Basalt, and Columbia River Basalt and Dalles Formation. The John Day Formation, the only unit studied in detail, consists of about 4,000 feet of tuff, lapilli tuff, strongly to weakly welded rhyolite ash flows, and less abundant trachyandesite flows and rhyolite flows and domes. The formation was divided into nine mappable members in part of the area, primarily on the basis of distinctive ledge-forming welded ash-flow sheets. Most of the sheets are composed of stony rhyolite containing abundant lithophysae and sparse phenocrysts. One sheet contains 10 to 20 percent phenocrysts, mostly cryptoperthitic soda sanidine, but including less abundant quartz, myrmekitic intergrowths of quartz and sanidine, and oligoclase. The rhyolitic ash flows and lava flows were extruded from nearby vents, in contrast to some of the interbedded air-fall tuff and lapilli tuff of dacitic and andesitic composition that may have been derived from vents in an ancestral Cascade Range. The John Day is dated on the basis of a late Oligocene flora near the base of the formation and early Miocene faunas near the top of the formation. The middle Miocene and older rocks in the Antelope-Ashwood area are broadly folded and broken along northeast-trending faults. Over much of the area the rocks dip gently eastward from the crest of a major fold and are broken along a series of steeply dipping antithetic strike faults. Pliocene and Quaternary strata appear to be undeformed. At the Priday agate deposit, chalcedony-filled spherulites (thunder-eggs) occur in the lower part of a weakly welded rhyolitic ash flow. The so-called thunder-eggs are small spheroidal bodies, about 3 inches in average diameter; each consists of a chalcedonic core surrounded by a shell of welded tuff that is altered to radially oriented fibers of cristobalite and alkalic feldspar.

2007-04-23

Systems biology recognizes the complex multi-scale organization of biological systems, from molecules to ecosystems. The International Symposium on Systems Biology is an annual two-day event gathering the most influential researchers transforming biology into an integrative discipline investigating complex systems. In recognition of the fundamental similarity between the scientific problems addressed in environmental science and systems biology studies at the molecular, cellular, and organismal levels, the 2007 Symposium featured global leaders in “Systems Biology and the Environment.” The objective of the 2007 “Systems Biology and the Environment” International Symposium was to stimulate interdisciplinary thinking and research that spans systems biology andmore » environmental science. This Symposium was well aligned with the DOE’s Genomics: GTL program efforts to achieve scientific objectives for each of the three DOE missions: Develop biofuels as a major secure energy source for this century; Develop biological solutions for intractable environmental problems; Understand biosystems’ climate impacts and assess sequestration strategies. Our scientific program highlighted world-class research exemplifying these priorities. The Symposium featured 45 minute lectures from 12 researchers including: Penny/Sallie Chisholm of MIT gave the keynote address “Tiny Cells, Global Impact: What Prochlorococcus Can Teach Us About Systems Biology”, plus Jim Fredrickson of PNNL, Nitin Baliga of ISB, Steve Briggs of UCSD, David Cox of Perlegen Sciences, Antoine Danchin of Institut Pasteur, John Delaney of the U of Washington, John Groopman of Johns Hopkins, Ben Kerr of the U of Washington, Steve Koonin of BP, Elliott Meyerowitz of Caltech, and Ed Rubin of LBNL. The 2007 Symposium promoted DOE’s three mission areas among scientists from multiple disciplines representing academia, non-profit research institutions, and the private sector. As in all previous Symposia, we had excellent attendance of participants representing 20-30 academic or research-oriented facilities along with 25-30 private corporations from 5-10 countries. To broaden the audience for the Symposium and ensure the continued accessibility of the presentations, we made the presentation videos available afterward on the ISB’s website.« less

Ventilation rates in recently constructed U.S. school classrooms.

2017-09-01

Low ventilation rates (VRs) in schools have been associated with absenteeism, poorer academic performance, and teacher dissatisfaction. We measured VRs in 37 recently constructed or renovated and mechanically ventilated U.S. schools, including LEED and EnergyStar-certified buildings, using CO 2 and the steady-state, build-up, decay, and transient mass balance methods. The transient mass balance method better matched conditions (specifically, changes in occupancy) and minimized biases seen in the other methods. During the school day, air change rates (ACRs) averaged 2.0±1.3 hour -1 , and only 22% of classrooms met recommended minimum ventilation rates. HVAC systems were shut off at the school day close, and ACRs dropped to 0.21±0.19 hour -1 . VRs did not differ by building type, although cost-cutting and comfort measures resulted in low VRs and potentially impaired IAQ. VRs were lower in schools that used unit ventilators or radiant heating, in smaller schools and in larger classrooms. The steady-state, build-up, and decay methods had significant limitations and biases, showing the need to confirm that these methods are appropriate. Findings highlight the need to increase VRs and to ensure that energy saving and comfort measures do not compromise ventilation and IAQ. © 2017 John Wiley & Sons A/S.

PIT-tags recovered from tern and cormorant breeding colonies at Rice Island and observations from the interrogation systems at John Day and Bonneville Dams were incorporated into survival analyses. Whether the estimates for the upper reaches of the system, between Lower Granite and McNary Dams were as expected (with weighted averages S{sub LGR-LGS} = 0.996, S{sub LGS-LMN} = 0.837, and S{sub LMN-McN} = 0.941), those for the lower reaches, between John Day and Bonneville Dams, appeared positively biased with survival estimates typically greater than 1. Their weighted averages were S{sub McN-JDA} = 0.707 and S{sub JDA-BON} = 1.792 for 1997 releases.more » For the 1998 releases, they were S{sub McN-JDA} = 0.795 and S{sub JDA-BON} = 1.312. If the estimates for the lower reaches were biased, the estimates for the whole project would also be biased (S{sub LGR-BON} = 0.819). We determined that bias could have arisen if the terns and cormorants of Rice Island fished for salmon yearlings in waters of the BON-Rice reach at low rates (M{sub BON-Rice} {le} 0.2), and the rates of tag-deposition and tag-detection were low (R{sub D} x R{sub R} {le} 0.4). Moreover, unknown levels of uncensored post-detection mortality and scavenging of previously dead salmon yearlings may have also added to the bias.« less

Type 2 diabetes mellitus (T2DM) is associated with peripheral insulin resistance, impaired incretin effect, and increased plasma levels of tumour necrosis factor-alpha (TNF-α). Although TNF-α infusion at a dose that induces systemic inflammation in healthy volunteers has been demonstrated to induce peripheral insulin resistance, the influence of this cytokine on the incretin effect is unknown. We investigated whether systemic inflammation induced by TNF-α infusion in healthy volunteers alters the incretin hormone response to oral and intravenous glucose loads in a crossover study design with ten healthy male volunteers (mean age 24 years, mean body mass index 23.7 kg/m(2) ). The study consisted of four study days: days 1 and 2, 6-h infusion of saline; days 3 and 4, 6-h infusion of TNF-α; days 1 and 3, 4-h oral glucose tolerance test; and days 2 and 4, 4-h corresponding intravenous isoglycaemic glucose tolerance test. Glucose tolerance tests were initiated after 2 h of saline/TNF-α infusion. Plasma concentrations of TNF-α, interleukin 6, glucose, incretin hormones, and cortisol, and serum concentrations of C-peptide and insulin were measured throughout the study days. Insulin sensitivity was estimated by the Matsuda index and homeostasis model assessment of insulin resistance (HOMA-IR). Prehepatic insulin secretion rates were calculated. TNF-α infusion induced symptoms of systemic inflammation; increased plasma levels of cortisol, TNF-α, and interleukin 6; and increased the HOMA-IR. The secretion of incretin hormones as well as the incretin effect remained unchanged. In healthy young male volunteers, acute systemic inflammation induced by infusion of TNF-α is associated with insulin resistance with no change in the incretin effect.

Increasing physical damage on coral reefs from predation, storms and anthropogenic disturbances highlights the need to understand the impact of injury on the coral immune system. In this study, we examined the regulation of the coral immune response over 10 days following physical trauma artificially inflicted on in situ colonies of the coral Acropora aspera, simultaneously with bacterial colonization of the lesions. Corals responded to injury by increasing the expression of immune system-related genes involved in the Toll-like and NOD-like receptor signalling pathways and the lectin-complement system in three phases (<2, 4 and 10 days post-injury). Phenoloxidase activity was also significantly upregulated in two phases (<3 and 10 days post-injury), as were levels of non-fluorescent chromoprotein. In addition, green fluorescent protein expression was upregulated in response to injury from 4 days post-injury, while cyan fluorescent protein expression was reduced. No shifts in the composition of coral-associated bacterial communities were evident following injury based on 16S rRNA gene amplicon pyrosequencing. Bacteria-specific fluorescence in situ hybridization also showed no evidence of bacterial colonization of the wound or regenerating tissues. Coral tissues showed near-complete regeneration of lesions within 10 days. This study demonstrates that corals exhibit immune responses that support rapid recovery following physical injury, maintain coral microbial homeostasis and prevent bacterial infestation that may compromise coral fitness. © 2015 John Wiley & Sons Ltd.

BK virus-associated hemorrhagic cystitis (BKV-HC) is a common and major cause of morbidity in recipients of allogeneic hematopoietic stem cell transplantation. A 32-year-old woman developed severe BKV-HC on day 24 after cord blood transplantation (CBT). Despite supportive therapies - such as hyperhydration, forced diuresis, and urinary catheterization - macroscopic hematuria and bladder irritation persisted for over a month. Hyperbaric oxygen (HBO) therapy at 2.1 atmospheres for 90 min per day was started on day 64 after CBT. Macroscopic hematuria resolved within a week, and microscopic hematuria was no longer detectable within 2 weeks. Hematuria did not recur after 11 sessions of HBO therapy, and no significant side effects were observed during or after treatment. HBO therapy could thus be useful in controlling refractory BKV-HC after CBT. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

In 1982 the NPPC included in its Fish and Wildlife Program a measure that called for studies ''... to investigate juvenile salmon and steelhead losses to predators while these fish are migrating through Columbia and Snake River reservoirs.'' In the same year the Bonneville Power Administration (BPA) funded ODFW and FWS to conduct collaborative studies to estimate the number of juvenile salmonids lost to predators in John Day Reservoir. Also included as study objectives were: (1) a description of the importance of predation losses relative to mortality at the dam and total reservoir mortality; (2) a description of how predationmore » losses might vary (spatially and temporally); and (3) recommendations of measures to control predation on smolts. We studied four species of predator: northern squawfish, walleye, smallmouth bass, and channel catfish. We selected John Day Reservoir as the study site because the following factors led us to believe if predation was a problem in any reservoir, it would be most obvious there because: (1) the reservoir is an important subyearling chinook rearing area; (2) passage and residualism of juvenile salmonids were considered a problem there; and (3) substantial populations of predators were known to reside in the reservoir.

US Army Corps of Engineers - Portland District required that a two-dimensional (2D) depth-averaged and a three-dimensional (3D) free-surface numerical models to be developed and validated for the John Day tailrace. These models were used to assess potential impact of a select group of structural and operational alternatives to tailrace flows aimed at improving fish survival at John Day Dam. The 2D model was used for the initial assessment of the alternatives in conjunction with a reduced-scale physical model of the John Day Project. A finer resolution 3D model was used to more accurately model the details of flow inmore » the stilling basin and near-project tailrace hydraulics. Three-dimensional model results were used as input to the Pacific Northwest National Laboratory particle tracking software, and particle paths and times to pass a downstream cross section were used to assess the relative differences in travel times resulting from project operations and structural scenarios for multiple total river flows. Streamlines and neutrally-buoyant particles were seeded in all turbine and spill bays with flows. For a Total River of 250 kcfs running with the Fish Passage Plan spill pattern and a spillwall, the mean residence times for all particles were little changed; however the tails of the distribution were truncated for both spillway and powerhouse release points, and, for the powerhouse releases, reduced the residence time for 75% of the particles to pass a downstream cross section from 45.5 minutes to 41.3 minutes. For a total river of 125 kcfs configured with the operations from the Fish Passage Plan for the temporary spillway weirs and for a proposed spillwall, the neutrally-buoyant particle tracking data showed that the river with a spillwall in place had the overall mean residence time increase; however, the residence time for 75% of the powerhouse-released particles to pass a downstream cross section was reduced from 102.4 min to 89 minutes.« less

The complement system is activated in liver diseases including acute liver failure (ALF); however, the role of the lectin pathway of complement has scarcely been investigated in ALF. The pathway is initiated by soluble pattern recognition molecules: mannan-binding lectin (MBL), M-, L-, and H-ficolin and collectin-liver-1 (CL-L1), which are predominantly synthesized in the liver. We aimed to study lectin levels in ALF patients and associations with clinical outcome. Serum samples from 75 patients enrolled by the US ALF Study Group were collected on days 1 and 3. We included 75 healthy blood donors and 20 cirrhosis patients as controls. Analyses were performed using sandwich-type immunoassays (ELISA, TRIFMA). At day 1, the MBL level in ALF patients was 40% lower compared with healthy controls {[median (interquartile range) 0.72 μg/ml(0.91) vs. 1.15 (1.92)(P = 0.02]}, and increased significantly by day 3 [0.83 μg/ml(0.94)(P = 0.01)]. The M-ficolin level was 60% lower [0.54 μg/ml(0.50) vs. 1.48(1.01)(P < 0.0001)]. The CL-L1 level at day 1 was slightly higher compared with healthy controls [3.20 μg/ml(2.37) vs. 2.64(0.72)(P = 0.11)]; this was significant at day 3 [3.35(1.84)(P = 0.006)]. H- and L-ficolin levels were similar to healthy controls. Spontaneous ALF survivors had higher levels of MBL at day 1 [0.96 μg/ml(1.15) vs. 0.60(0.60)(P = 0.02)] and lower levels of L-ficolin by day 3 compared with patients who died or were transplanted [1.61 μg/ml(1.19) vs. 2.17(2.19)(P = 0.02)]. We observed significant dynamics in lectin levels in ALF patients, which may suggest they play a role in ALF pathogenesis. High MBL and low L-ficolin levels are associated with survival. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To assess the amount of debris extruded apically during root canal preparation using various nickel titanium instrumentation systems and hand files in primary molar teeth. Sixty extracted primary first mandibular molar human teeth were randomly assigned to four groups (n = 15 teeth for each group). The canals were then instrumented with the following instrument systems: Revo-S, Mtwo, ProTaper Next, and hand files. Apically extruded debris during instrumentation was collected into pre-weighed Eppendorf tubes. The Eppendorf tubes were then stored in an incubator at 70°C for 5 days. The weight of the dry extruded debris was established by subtracting the pre-instrumentation and post-instrumentation weight of the Eppendorf tubes for each group. The data were analyzed using one-way analysis of variance (anova) and Tukey's post hoc tests. ProTaper Next files were associated with less apically extruded debris than the Mtwo, Revo-S, and hand files (P < 0.05). Hand files extruded more debris than Mtwo and Revo-S instruments (P < 0.05), but there was no significant difference found between the Mtwo and Revo-S instruments (P > 0.05). All instruments were associated with apical extrusion of debris. ProTaper Next files caused less debris extrusion compared to the other systems used. © 2015 BSPD, IAPD and John Wiley & Sons A/S.

To address the hypothesis that pre-eclampsia (PE) impacts the fetal immune system, we investigated the prevalence of distinct immune cell subsets along with plasma cortisol and cytokine levels in pre-term newborns of PE mothers. Cord blood and peripheral blood samples on the 1st, 3rd and 7th postnatal days of life were collected from 14 pre-term infants affected by PE and 14 non-PE pregnancies. We measured plasma cortisol and cytokine levels with immunoassays and assessed the prevalence of T, NK and DC subsets using flow cytometry. The prevalence of CD4+ cells was lower in PE infants, while that of memory T cells was higher. Myeloid DCs had a lower prevalence in PE neonates. Cytokine and cortisol levels were lower in PE neonates. Our observations show that PE pregnancies are associated with altered newborn immune status during the first week of life. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

A finding in the autopsy of John Paul Jones, the American Revolutionary War naval hero, may explain his terminal illness. During his last 2 years, he had a persistent productive cough and dyspnea. Ten days before death, he developed rapidly progressive dependent edema and ascites. He died in France in 1792. His body, preserved in alcohol in a lead coffin, was, in 1905, removed to the United States. Glomerulonephritis was noted on an autopsy, performed in France, but there was no comment then or since about ventricular wall thickness being the same in both ventricles at 5-6 mm. Hypertrophy and dilatation with biventricular failure followed by tissue shrinkage during 113 years in alcohol could have resulted in these ventricular wall findings. Systemic hypertension and left ventricular failure are consistent with his respiratory symptoms complicated perhaps by pulmonary emboli, right ventricular failure with tricuspid regurgitation, peripheral congestion, and jaundice. © 2015 American Academy of Forensic Sciences.

Nocturnal hypoglycaemia in type 1 diabetes--consequences and assessment.

Hypoglycaemia is inevitable when striving for low HbA1c values. Nocturnal hypoglycaemia often occurs without symptoms, but results in diminished next day well-being and hypoglycaemia unawareness. Frequency of nocturnal hypoglycaemia was first assessed in research ward settings, but suffered from insufficient glucose sampling frequency. This may have resulted in overestimation of the duration of hypoglycaemic episodes. The advent of the first continuous glucose sensor, the needle-type MedtronicMiniMed Continuous Glucose Measurement System, revolutionized the assessment of glucose values. However, on scrutiny, the first version of this sensor showed a drift into the hypoglycaemic area and delayed recovery from hypoglycaemia. Using the microdialysis-based GlucoDay system, our group reported a lower frequency of nocturnal hypoglycaemia in type 1 diabetes patients using an insulin pump, than that expected from the existing literature. Today, more than 80 years after the introduction of insulin for the treatment of type 1 diabetes, the associated frequency of nocturnal hypoglycaemia still awaits its definitive assessment.

Anaplastic lymphoma kinase (ALK)-rearranged non-small-cell lung cancer (NSCLC) is a distinct subtype with patients showing peculiar clinicopathological features and dramatic responses to the ALK tyrosine kinase inhibitor crizotinib. Patients with this cancer variant have a dismal prognosis and limited treatment options when it has progressed to intracranial metastasis because of inadequate drug penetration into the central nervous system (CNS). Factors associated with response to TKI therapy have been reported to include pharmacokinetic and biodynamic resistance phenomena. In our NSCLC patient with multiple intracranial metastases, we administered high-dose pulsatile crizotinib therapy (1000 mg/d) on a one-day-on/one-day-off basis. A significant central nervous system (CNS) response was achieved, and time to neurological progression was prolonged to 6 months. High-dose pulsatile therapy may be an effective dosing strategy for crizotinib in NSCLC showing progression to metastasis in the brain. © 2017 John Wiley & Sons Ltd.

Nonessential allergy diets in children with mild symptoms may harm the development of immunological tolerance and impose a burden on families and day care. We aimed to reduce the high prevalence of allergy diets in day care by reforming the practices for inquiring about need of special diets from parents. We developed a new special diet form and an information leaflet based on the new allergy guidelines. The new form was implemented into 40 Finnish day care centres in the capital region in 2013-2015. The questionnaires on practices concerning special diets in day care centres and allergy knowledge were collected from the personnel. After 2 years, the new special diet form was used by 64% of families with food-allergic children, and the prevalence of allergy diets in day care centres decreased by 43% to 4.3% (IQ range 3.05-5.96). A significant decrease was found in the prevalence of all basic (milk, grains, egg) and most other allergy diets (P for trend < 0.01). The new practice was well accepted by day care and kitchen personnel. Lack of updated allergy knowledge was noted among day care personnel. The burden of allergy diets in day care settings could be decreased by simple pragmatic changes based on current allergy guidelines. Old allergy attitudes persisted among day care personnel, indicating the need for continuous education. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Estimated power quality for line commutated photovoltaic residential system

NASA Astrophysics Data System (ADS)

McNeill, B. W.; Mirza, M. A.

1983-10-01

A residential photovoltaic system using a line commutated inverter is modeled using a single diode model for the solar cells and a four switch model for the inverter. The model predicts power factor and total harmonic distortion as a function of solar radiation, array voltage, inverter output voltage, and inverter filter capacitor and inductor size. The model was run using parameter values appropriate for the John F. Long PV System and the predicted results compared well with measured results from the system. The model shows that improvements in total harmonic distortion are made at the expense of the power factor. The harmonic distortion is least when the inverter is operating at just continuous conduction. The total harmonic distortion can be kept to less than 0.17 all day if a variable inductor is used in the inverter's input filters.

Passiflora incarnata L. (Passifloraceae) has been traditionally used for treatment of anxiety, insomnia, drug addiction, mild infections, and pain. The aim of this study was to investigate the effect of a commercial extract of P. incarnata in the analgesia induced by alcohol withdrawal syndrome in rats. In addition, brain-derived neurotrophic factor and interleukin-10 levels were evaluated in prefrontal cortex, brainstem, and hippocampus. Male adult rats received by oral gavage: (1: water group) water for 19 days, 1 day interval and water (8 days); (2: P. incarnata group) water for 19 days, 1 day interval and P. incarnata 200 mg/kg (8 days); (3: alcohol withdrawal group) alcohol for 19 days, 1 day interval and water (8 days); and (4: P. incarnata in alcohol withdrawal) alcohol for 19 days, 1 day interval and P. incarnata 200 mg/kg (8 days). The tail-flick and hot plate tests were used as nociceptive response measures. Confirming previous study of our group, it was showed that alcohol-treated groups presented an increase in the nociceptive thresholds after alcohol withdrawal, which was reverted by P. incarnata, measured by the hot plate test. Besides, alcohol treatment increased brain-derived neurotrophic factor and interleukin-10 levels in prefrontal cortex, which was not reverted by P. incarnata. Considering these results, the P. incarnata treatment might be a potential therapy in the alcohol withdrawal syndrome. Copyright © 2017 John Wiley & Sons, Ltd.

Heart rate variability (HRV) has been rarely applied in elite athletes prior to competition. The aim of this study was to examine the changes in HRV in elite female volleyball players before a stressful match during play offs and to evaluate the impact on sport-specific performance. A short-term resting HRV analysis was applied right after the night sleep in ten female athletes 1 and 2 days prior to the match and the day of the competition. Approaching the decisive match, RR interval, resting heart rate (HR), pNN50, rMSDD and SD1 did not significantly vary. SD2 significantly increased in comparison with first-day measurement (P<0·05). HF% levels significantly decreased the prematch day and the match day (P<0·05); however, no significant changes in LF/HF% ratio were observed. A gradual increase in VLF% and in LnVLF was observed, with a significant difference between first-day and match-day measurements (P<0·01 and P<0·05, respectively). The number of positive receptions was inversely correlated with LF/HFms(2) ratio, with LF/HF% ratio (R = -0·98, P<0·05 for both) and with resting HR (R = -0·92, P<0·05). Elite female athletes practising team sports exhibit a slight change in HRV prior to a decisive competition, without a pronounced variation of the autonomic nervous system activity. A day-to-day HRV measurement could be a useful tool to evaluate the impact of a competition on the autonomic nervous system in athletes, also considering the relationship between sympathetic activity and athletic performance. © 2013 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

Irritant exposure may be a contributory cause or the sole cause of (occupational) hand dermatitis. However, the documentation of irritant exposures in clinical practice is not standardized. To examine the feasibility and usefulness of a form with different items addressing both occupational and non-occupational irritant exposures in a semiquantitative way. Between May 2016 and May 2017, successive patients with work-related hand dermatitis, irrespective of aetiology, were examined in 9 specialized European departments. Department-specific investigation was supplemented with the above proforma. The results were recorded by use of an anonymized secured online documentation system in a pilot study. Altogether, 193 patients were included; 114 females and 79 males, with a mean age of 40 years (range 18-68 years). The most common occupational group comprised healthcare workers (n = 35); occupational exposure of the hands to gloves, dusts and water without detergents of >2 hours/day was seen in 54.5%, 24.4% and 24.3% of patients, respectively. Non-occupational exposures rarely exceeded 2 hours/day. It is hoped that the set of descriptors will offer a basis for (clinical) epidemiological studies assessing the role of irritant exposures in occupational hand dermatitis, and to support a high level of quality and consistency in daily patient care. © 2018 John Wiley & Sons A/S.

Hydrogeology in the area of a freshwater lens in the Floridan aquifer system, northeast Seminole County, Florida

USGS Publications Warehouse

Phelps, G.G.; Rohrer, K.P.

1987-01-01

Northeast Seminole County, Florida, contains an isolated recharge area of the Floridan aquifer system that forms a freshwater lens completely surrounded by saline water. The freshwater lens covers an area of about 22 sq mi surrounding the town of Geneva, and generally is enclosed by the 25 ft land surface altitude contour. Thickness of the lens is about 350 ft in the center of the recharge area. The geohydrologic units in descending order consist of the post-Miocene sand and shell of the surficial aquifer; Miocene clay, sand, clay, and shell that form a leaky confining bed; and permeable Eocene limestones of the Floridan aquifer system. The freshwater lens is the result of local rainfall flushing ancient seawater from the Floridan aquifer system. Sufficient quantities of water for domestic and small public supply systems are available from the Floridan aquifer system in the Geneva area. The limiting factor for water supply in the area is the chemical quality of the water. Chloride concentrations range from < 20 mg/L in the center of the recharge area to about 5,100 mg/L near the St. Johns River southeast of Geneva. Constituents analyzed included sulfate (range 1 to 800 mg/L), hardness (range 89 to 2,076 mg/L), and iron (range 34 to 6,600 mg/L). Because the freshwater lens results entirely from local recharge, the long-term sustained freshwater yield of the aquifer in the Geneva area depends on the local recharge rate. In 1982, recharge was about 13 inches (13.8 million gal/day). Average recharge for 1941 through 1970 was estimated to be about 11 inches (11.3 million gal/day). Freshwater that recharges the aquifer in the Geneva area is either pumped out or flows north and northeast to discharge near or in the St. Johns River. Average annual outflow from the lens is about 10 in/yr. No measurable change in the size or location of the freshwater lens has occurred since studies in the early 1950's. (Lantz-PTT)

1972-01-01

A dynamic preferential runway system (DPRS) was developed for John F. Kennedy International Airport for the purpose of controlling short term noise exposure in the neighboring communities. The DPRS is a computer-aided procedure for optimum selection of runways from the standpoint of noise and is based upon a community disturbance model which takes into account flyover levels, size of exposed populations, time of day and week, and persistence of overflights. A preliminary evaluation of the DPRS is presented on the basis of social survey data and telephone complaint records, for the trial period of August and September, 1971. Comparative use is made of data taken in a previous survey of the same community areas in 1969.

Together, a group of Canadian colleagues from St. John's, Newfoundland, Calgary, Alberta (some via Doha) and London, Ontario introduced the first Train the Trainer in Simulation-Based Learning (TTT-SBL) program in Mzuzu Central Hospital and Mzuzu University in Malawi. The team led by Elaine Sigalet (Doha) and consisting of Ian Wishart (Calgary), Faizal Haji (London) and Adam Dubrowski (St. John's) was invited to Malawi by Norman Lufesi to conduct a two-day TTT-SBL course for facilitators who teach an Emergency Triage, Assessment and Treatment (ETAT) plus Trauma course. The following technical report describes this course.  All trainees-facilitators who took part in the first iteration of the TTT-SBL course were asked to participate in teaching an ETAT course and modify it to include elements of simulation. The new format of ETAT resulted in a reduction of time necessary to conduct the course from four days (based on historical data) to 2.5 days. PMID:28580202

Complement is a central defence against sepsis, and increasing complement insufficiency in neonates of greater prematurity may predispose to increased sepsis. Ureaplasma spp. are the most frequently cultured bacteria from preterm blood samples. A sheep model of intrauterine Ureaplasma parvum infection was used to examine in vivo Ureaplasma bacteraemia at early and late gestational ages. Complement function and Ureaplasma killing assays were used to determine the correlation between complement potency and bactericidal activity of sera ex vivo. Ureaplasma was cultured from 50% of 95-day gestation lamb cord blood samples compared to 10% of 125-day gestation lambs. Bactericidal activity increased with increased gestational age, and a direct correlation between functional complement activity and bactericidal activity (R 2 =.86; P<.001) was found for 95-day gestational lambs. Ureaplasma bacteraemia in vivo was confined to early preterm lambs with low complement function, but Ureaplasma infection itself did not diminish complement levels. © 2016 John Wiley & Sons A/S.

Obituary: John Louis Perdrix, 1926-2005

NASA Astrophysics Data System (ADS)

Orchiston, D. Wayne

2006-12-01

John Perdrix, astronomical historian and co-founder of the Journal of Astronomical History and Heritage, died on 27 June 2005. John Louis Perdrix was born in Adelaide, Australia, on 30 June 1926. After studying chemistry at Melbourne Technical College and working in industry, he joined the Commonwealth Scientific and Industrial Research Organisation's Division of Minerals and Geochemistry. In 1974 the Division relocated to the Western Australian capital, Perth, and John spent the rest of his working life there involved in geochemical research. From his teenage years John had a passion for astronomy, which he fine-tuned through the Astronomical Society of Victoria and the Victorian Branch of the British Astronomical Association. He was very active in both groups, serving as President of the former and Secretary/Treasurer of the latter. He was also an FRAS, and a member of the AAS, the BAA parent body, and the IAU (Commission 41)?no mean feat for an Australian amateur astronomer. Throughout his life, he was a strong advocate of close amateur-professional relations. John's main research interest was history of astronomy, and over the years he wrote a succession of research papers, mainly about aspects of Australian astronomy. His well-researched and neatly-illustrated papers on the Melbourne Observatory and the Great Melbourne Telescope are classics, and when the Observatory's future was in the balance they played a key role in the State Government's decision to convert this unique facility into a museum precinct. To support his research activities, John built up an amazing library that developed its own distinctive personality and quickly took over his house and garage before invading commercial storage facilities! Apart from writing papers, John had an even greater passion for editing and publishing. From 1985 to 1997 he produced the Australian Journal of Astronomy, and in 1998 this was replaced by the Journal of Astronomical History and Heritage (JAH2). Both journals appeared under the banner of his own publishing house, Astral Press, until 2005 when JAH2 was transferred to the Centre of Astronomy at James Cook University. When cancer was first diagnosed, this did not deter John, and he continued to pursue his astronomical and editorial interests. Early in 2005 the cancer was in remission and John decided to make one final overseas trip, a long-anticipated visit to St. Petersburg. It was while he was returning to Australia that the illness aggressively reappeared, and he was taken off the airplane at Dubai and died peacefully in Rashid Hospital three days later. He was just three days short of his seventy-ninth birthday. Always the consummate gentleman, John Perdrix had a keen sense of humor and was wonderful company. He will be greatly missed by all who knew him. Our condolences go to his six children, Louise, John, Timothy, Fleur, Lisa and Angella.

Umbilical cord matrix (UCM)-derived mesenchymal stem/stromal cells (MSCs) are promising therapeutic candidates for regenerative medicine settings. UCM MSCs have advantages over adult cells as these can be obtained through a non-invasive harvesting procedure and display a higher proliferative capacity. However, the high cell doses required in the clinical setting make large-scale manufacturing of UCM MSCs mandatory. A commercially available human platelet lysate-based culture supplement (UltraGRO TM , AventaCell BioMedical) (5%(v/v)) was tested to effectively isolate UCM MSCs and to expand these cells under (1) static conditions, using planar culture systems and (2) stirred culture using plastic microcarriers in a spinner flask. The MSC-like cells were isolated from UCM explant cultures after 11 ± 2 days. After five passages in static culture, UCM MSCs retained their immunophenotype and multilineage differentiation potential. The UCM MSCs cultured under static conditions using UltraGRO TM -supplemented medium expanded more rapidly compared with UCM MSCs expanded using a previously established protocol. Importantly, UCM MSCs were successfully expanded under dynamic conditions on plastic microcarriers using UltraGRO TM -supplemented medium in spinner flasks. Upon an initial 54% cell adhesion to the beads, UCM MSCs expanded by >13-fold after 5-6 days, maintaining their immunophenotype and multilineage differentiation ability. The present paper reports the establishment of an easily scalable integrated culture platform based on a human platelet lysate supplement for the effective isolation and expansion of UCM MSCs in a xenogeneic-free microcarrier-based system. This platform represents an important advance in obtaining safer and clinically meaningful MSC numbers for clinical translation. Copyright © 2016 John Wiley & Sons, Ltd.

Human periosteal-derived cell expansion in a perfusion bioreactor system: proliferation, differentiation and extracellular matrix formation.

Sonnaert, M; Papantoniou, I; Bloemen, V; Kerckhofs, G; Luyten, F P; Schrooten, J

2017-02-01

Perfusion bioreactor systems have shown to be a valuable tool for the in vitro development of three-dimensional (3D) cell-carrier constructs. Their use for cell expansion, however, has been much less explored. Since maintenance of the initial cell phenotype is essential in this process, it is imperative to obtain insight into the bioreactor-related variables determining cell fate. Therefore, this study investigated the influence of fluid flow-induced shear stress on the proliferation, differentiation and matrix deposition of human periosteal-derived cells in the absence of additional differentiation-inducing stimuli; 120 000 cells were seeded on additive manufactured 3D Ti6Al4V scaffolds and cultured for up to 28 days at different flow rates in the range 0.04-6 ml/min. DNA measurements showed, on average, a three-fold increase in cell content for all perfused conditions in comparison to static controls, whereas the magnitude of the flow rate did not have an influence. Contrast-enhanced nanofocus X-ray computed tomography showed substantial formation of an engineered neotissue in all perfused conditions, resulting in a filling (up to 70%) of the total internal void volume, and no flow rate-dependent differences were observed. The expression of key osteogenic markers, such as RunX2, OCN, OPN and Col1, did not show any significant changes in comparison to static controls after 28 days of culture, with the exception of OSX at high flow rates. We therefore concluded that, in the absence of additional osteogenic stimuli, the investigated perfusion conditions increased cell proliferation but did not significantly enhance osteogenic differentiation, thus allowing for this process to be used for cell expansion.

Development of a System-Wide Predator Control Program: Stepwise Implementation of a Predation Index, Predator Control Fisheries, and Evaluation Plan in the Columbia River Basin; Northern Pikeminnow Management Program, 2001 Annual Report.

Porter, Russell G.; Winther, Eric C.; Fox, Lyle G.

2003-03-01

This report presents results for year eleven in a basin-wide program to harvest northern pikeminnow (Ptychocheilus oregonensis). This program was started in an effort to reduce predation by northern pikeminnow on juvenile salmonids during their emigration from natal streams to the ocean. Earlier work in the Columbia River Basin suggested predation by northern pikeminnow on juvenile salmonids might account for most of the 10-20% mortality juvenile salmonids experience in each of eight Columbia River and Snake River reservoirs. Modeling simulations based on work in John Day Reservoir from 1982 through 1988 indicated that, if predator-size northern pikeminnow were exploited atmore » a 10-20% rate, the resulting restructuring of their population could reduce their predation on juvenile salmonids by 50%. To test this hypothesis, we implemented a sport-reward angling fishery and a commercial longline fishery in the John Day Pool in 1990. We also conducted an angling fishery in areas inaccessible to the public at four dams on the mainstem Columbia River and at Ice Harbor Dam on the Snake River. Based on the success of these limited efforts, we implemented three test fisheries on a system-wide scale in 1991--a tribal longline fishery above Bonneville Dam, a sport-reward fishery, and a dam-angling fishery. Low catch of target fish and high cost of implementation resulted in discontinuation of the tribal longline fishery. However, the sport-reward and dam-angling fisheries were continued in 1992 and 1993. In 1992, we investigated the feasibility of implementing a commercial longline fishery in the Columbia River below Bonneville Dam and found that implementation of this fishery was also infeasible.« less

Albumin infusion improves renal blood flow autoregulation in patients with acute decompensation of cirrhosis and acute kidney injury.

In cirrhotic patients with renal failure, renal blood flow autoregulation curve is shifted to the right, which is consequent upon sympathetic nervous system activation and endothelial dysfunction. Albumin infusion improves renal function in cirrhosis by mechanisms that are incompletely understood. We aimed to determine the effect of albumin infusion on systemic haemodynamics, renal blood flow, renal function and endothelial function in patients with acute decompensation of cirrhosis and acute kidney injury. Twelve patients with refractory ascites and 10 patients with acute decompensation of cirrhosis and acute kidney injury were studied. Both groups were treated with intravenous albumin infusion, 40-60 g/days over 3-4 days. Cardiac and renal haemodynamics were measured. Endothelial activation/dysfunction was assessed using von Willebrand factor and serum nitrite levels. F2α Isoprostanes, resting neutrophil burst and noradrenaline levels were quantified as markers of oxidative stress, endotoxemia and sympathetic activation respectively. Albumin infusion leads to a shift in the renal blood flow autoregulation curve towards normalization, which resulted in a significant increase in renal blood flow. Accordingly, improvement of renal function was observed. In parallel, a significant decrease in sympathetic activation, inflammation/oxidative stress and endothelial activation/dysfunction was documented. Improvement of renal blood flow correlated with improvement in endothelial activation (r = 0.741, P < 0.001). The data suggest that albumin infusion improves renal function in acutely decompensated cirrhotic patients with acute kidney injury by impacting on renal blood flow autoregulation. This is possibly achieved through endothelial stabilization and a reduction in the sympathetic tone, endotoxemia and oxidative stress. © 2014 John Wiley & Sons A/S.

Monitoring and Evaluation of Yearling Fall Chinook Salmon (Oncorhynchus tshawytscha) Released from Acclimation Facilities Upstream of Lower Granite Dam; 2003 Annual Report.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rocklage, Stephen J.

The Nez Perce Tribe, in cooperation with the U.S. Fish and Wildlife Service and Washington Department of Fish and Wildlife, conducted monitoring and evaluation studies on Lyons Ferry Hatchery reared yearling fall Chinook salmon Oncorhynchus tshawytscha that were acclimated and released at three Fall Chinook Acclimation Project (FCAP) sites upstream of Lower Granite Dam in 2003. This was the eighth year of a long-term project to supplement natural spawning populations of Snake River stock fall Chinook salmon upstream of Lower Granite Dam. The 437,633 yearlings released from the Fall Chinook Acclimation Project facilities were short of the 450,000 fish quota.more » We use Passive Integrated Transponder (PIT) tag technology to monitor the primary performance measures of survival to mainstem dams and migration timing. We also monitor size, condition and tag/mark retention at release. We released 7,492 PIT tagged yearlings from Pittsburg Landing, 7,494 from Big Canyon and 2,497 from Captain John Rapids. Fish health sampling indicated that, overall, bacterial kidney disease levels at the acclimation facilities could be considered medium with 37-83% of the fish sampled rating medium to very high. Mean fork lengths (95% confidence interval) of the PIT tagged groups ranged from 153.7 mm (153.2-154.2 mm) at Captain John Rapids to 164.2 mm (163.9-164.5 mm) at Pittsburg Landing. Mean condition factors ranged from 1.06 at Lyons Ferry Hatchery to 1.22 at Captain John Rapids. Estimated survival (95% confidence interval) of PIT tagged yearlings from release to Lower Granite Dam ranged from 83.1% (80.7-85.5%) for Big Canyon to 91.7% (87.7-95.7%) for Captain John Rapids. Estimated survival from release to McNary Dam ranged from 59.9% (54.6-65.2%) for Big Canyon to 69.4% (60.5-78.4%) for Captain John Rapids. Median migration rates to Lower Granite Dam, based on all observations of PIT tagged yearlings from the FCAP facilities, ranged from 5.8 river kilometers per day (rkm/d) for Captain John Rapids to 16.2 rkm/d for Pittsburg Landing. Median migration rates to McNary Dam ranged from 11.7 rkm/d for Captain John Rapids to 17.6 rkm/d for Pittsburg Landing. Median travel times from the FCAP facilities were about 8-15 days to Lower Granite Dam and 22-27 days to McNary Dam. Median arrival dates at Lower Granite Dam, based on all observations of PIT tagged yearling groups from the FCAP facilities, ranged from April 23-25. Median arrival dates at McNary Dam for Pittsburg Landing, Big Canyon and Captain John Rapids groups ranged from May 4-10.« less

To evaluate the safety and efficiency of high-intensity focused ultrasound (HIFU) in the treatment of placenta accreta after vaginal delivery. Enrolled into this study between September 2011 and September 2013 were 12 patients who had been diagnosed with placenta accreta following vaginal delivery and who had stable vital signs. All patients were treated using an ultrasound-guided HIFU treatment system. As indication of the effectiveness of the treatment we considered decreased vascular index on color Doppler imaging, decrease in size of residual placenta compared with pretreatment size on assessment by three-dimensional ultrasound with Virtual Organ Computer-aided Analysis, reduced signal intensity and degree of enhancement on magnetic resonance imaging and avoidance of hysterectomy following treatment. To assess the safety of HIFU treatment, we recorded side effects, hemorrhage, infection, sex steroid levels, return of menses and subsequent pregnancy. Patients were followed up in this preliminary study until December 2013. The 12 patients receiving HIFU treatment had an average postpartum hospital stay of 6.8 days and an average period of residual placental involution of 36.9 days. HIFU treatment did not apparently increase the risk of infection or hemorrhage and no patient required hysterectomy. In all patients menstruation recommenced after an average of 80.2 days, and sex steroid levels during the middle luteal phase of the second menstrual cycle were normal. Two patients became pregnant again during the follow-up period. This preliminary study suggests that ultrasound-guided HIFU is a safe and effective non-invasive method to treat placenta accreta patients after vaginal delivery who have stable vital signs and desire to preserve fertility.

The goal of this work is to evaluate the association between organoleptic scores, oral condition and salivary β-galactosidases, to facilitate the differential diagnosis of halitosis in children. Fifty systemically healthy children with a primary complaint of oral malodour were included in this cross-sectional study. The organoleptic evaluation was carried out by two judges, evaluating the intensity of malodour of the air exhaled 5 s through the mouth of the patients, at a distance of approximately 10 cm from their noses; the level of salivary β-galactosidases was quantified spectrophotometrically after a chromatic reaction between a salivary sample of each patient and a specific chromatic substrate of the enzyme. Clinical conditions, such as visible plaque and gingival bleeding index, tongue coating score, localized food stagnation and other oral parameters, were evaluated by qualified dentists through an oral check-up. The β-galactosidase level was significantly related to the organoleptic scores and clinical parameters, such as the tongue coating score and the visible plaque index. Stratifying results with respect to the different phase of the day at which parents complained halitosis in their children, statistical analysis showed that the organoleptic scores and the level of β-galactosidases were significantly higher in children who suffered of halitosis during the whole day, A = 40%, with respect to those without this problem, N = 20% (P = 0.001 and P = 0.006, respectively). Certain oral parameters such as halitosis during the whole day, high tongue coating score and high visible plaque index were particularly associated with an increase in the salivary β-galactosidase level. © 2014 John Wiley & Sons A/S.

Tamhankar, Anup Sunil; Jatal, Sudhir; Saklani, Avanish

2016-12-01

This study aims to assess the advantages of Da Vinci Xi system in rectal cancer surgery. It also assesses the initial oncological outcomes after rectal resection with this system from a tertiary cancer center in India. Robotic rectal surgery has distinct advantages over laparoscopy. Total robotic resection is increasing following the evolution of hybrid technology. The latest Da Vinci Xi system (Intuitive Surgical, Sunnyvale, USA) is enabled with newer features to make total robotic resection possible with single docking and single phase. Thirty-six patients underwent total robotic resection in a single phase and single docking. We used newer port positions in a straight line. Median distance from the anal verge was 4.5 cm. Median robotic docking time and robotic procedure time were 9 and 280 min, respectively. Median blood loss was 100 mL. One patient needed conversion to an open approach due to advanced disease. Circumferential resection margin and longitudinal resection margins were uninvolved in all other patients. Median lymph node yield was 10. Median post-operative stay was 7 days. There were no intra-operative adverse events. The latest Da Vinci Xi system has made total robotic rectal surgery feasible in single docking and single phase. With the new system, four arm total robotic rectal surgery may replace the hybrid technique of laparoscopic and robotic surgery for rectal malignancies. The learning curve for the new system appears to be shorter than anticipated. Early perioperative and oncological outcomes of total robotic rectal surgery with the new system are promising.

2017-07-21

Gary Jordan (Host): Houston, we have a podcast. Welcome to the official podcast of the NASA Johnson Space Center, Episode 3, Landing from Space. I'm Gary Jordan, and I'll be your host today. So on this podcast, we bring in the experts -- NASA scientists, engineers, astronauts, pretty much all the folks that have the coolest information, the stuff you really want to know -- right on the show to tell you about everything NASA, everything from extraterrestrial dirt to the unknown parts of the universe. So today, we're talking landing from space with Dr. John Charles. He's the chief scientist for the NASA Human Research Program here at the NASA Johnson Space Center in Houston, Texas, and we talked about the more human side of space -- specifically, what happens to the human body in the microgravity environment and what that means for adjusting to life back on Earth, even on other planets, like Mars. I also had the chance to catch NASA Astronaut Shane Kimbrough just two days after landing from a 173-day mission aboard the International Space Station, and he gave a firsthand experience of what it feels like to adjust back to Earth's environment after living in space for that long. So with no further delay, let's go light speed and jump right ahead to our talk with Dr. John Charles and then NASA Astronaut Shane Kimbrough. Enjoy. [ Music ] Host: All right. Dr. Charles, welcome. Is it, should I say Dr. Charles or John? John Charles: Call me John. Host: John, okay. [laughs] All right. Well, John, thanks for coming on the show. We always seem to end up in the same circles first with the landing on Mars video and with speaking presentations, and, you know, you were the first person I thought of when we had this topic. But what's cool about this one is for this particular podcast, I actually got a chance to talk to Shane Kimbrough two days after he landed, which was awesome. I mean, he was really tired, but it was pretty cool to talk to him. Not to say that you're not a special guest, but-- John Charles: I'll try not to be as tired as you are. [ Laughs ] Host: Well, we're doing this I guess after lunchtime, so I can understand. John Charles: Yeah, that's possible. Yeah. Host: It is. But what's cool is that he was just getting adjusted to Earth. It was perspective, of such a unique perspective. He just came down, and he was still getting adjusted, and that takes weeks, right? That takes-- John Charles: Yes, it may take -- well, some folks say it takes as long to respond to or adjust back to Earth as it did in flight. So there is going to be ongoing adjustments, especially in the areas of, say, the bone loss, that will take months, and months, and months before they even come back to what they were approximately before flight. Host: Yeah. I mean, even some astronauts say they have, they still have dreams about floating. I mean, even floating and-- John Charles: Yeah. Host: They kind of, I guess their body just doesn't know where they are. John Charles: That, it's certainly, it is certainly a monumental experience, and I cannot imagine ever getting tired of it or used to it. I understand Peggy Whitson was excited to get the mission extension of three more months. Host: Right. John Charles: And she said she was actually interested in going back again. So I think once you've experienced the wonders of weightlessness, and the awesome view out the window, and all the other parts of going on a spaceflight these days, it's not something you ever get used to, and it probably colors your dreams for many, many years to come. Host: That's beautifully put way. John Charles: Thank you. Host: A beautiful way of saying it. But that's what I guess, you know, for, at least for Shane Kimbrough is kind of I guess happy to be home. You know, when we were interviewing him, his wife was not too far away. So he was, you know, I'm sure he's happy to see his family. John Charles: Sure. Host: But I was thinking, you know, why don't we start off with that conversation with Shane Kimbrough? Because he does talk about a lot of the human aspects, and he just says, you know, I'm dizzy and this is how I'm feeling. So I thought it would be cool if we kind of elaborated on that a little bit after. But first, let's start with Shane Kimbrough's interview. We do have to go back in time, so producer Alex, let's cue the wormhole sound effect thingy. [ Music ] Host: So if you need to take a breather, you know, let me know because it's just like talking, and then talking-- Shane Kimbrough: No, no. It's— Host: And then talking, and then talking. Shane Kimbrough: Good. [laughs] Let's knock it out. Host: Oh, man. So, wow. Okay, I know it's been a busy couple of days for you, but, you know, thanks for taking the time to actually set, you know, ten minutes aside to have this conversation. You just landed two days ago. That's pretty crazy. [laughs] But since we only do have, like, a short period of time, I thought we'd start, and if you can just kind of take us through the journey of starting at when you were saying your final goodbyes to Peggy, and to Thomas, and Oleg, and then you just closed the hatch, and then that journey all the way to where you, bam, smacked the ground. Shane Kimbrough: All right. Yeah, we were, you know, it was an anticipated moment when we were going to say goodbyes. We'd kind of been sitting around for about an hour waiting on the time to, when Sergey, the Soyuz commander, came and said, "It's time to go." So we did say our goodbyes. We gave hugs to all the other crew members we were leaving, like you said -- Peggy, and Thomas, and Oleg. We spent about four-and-a-half months together with them, so we spent a lot of time together, so we got to be really good friends and crewmates. So it was great with them, but it was, you know, we were heading home, and so we had to say our goodbyes, quickly shut the hatch right after we say goodbyes, and then we started preparing our vehicle with leak checks and everything, trying to make sure we were leak tight before we departed from the Space Station. Host: So a lot of, like, a lot of right to the procedures, right. Not a lot of reflection time. Shane Kimbrough: Absolutely. Host: Just right into it. Shane Kimbrough: We didn't have any time to mess around [laughs] because you, we do a leak check, then we get in our space suits, and then we get in the descent module, close the hatch to the other module, and then we depart pretty quickly. So all had to happen, you know, by the procedure. If we had any hiccup in that, then we wouldn't have been leaving that day. So it was pretty pressure packed trying to get to the undocking time. And so we undock, and then we actually, after you undock, you have about an hour and a half, which is an entire revolution around the Earth, to really not do much. So we took a little nap [laughs] because we were-- Host: Well deserved. Shane Kimbrough: Really tired. I mean, they had us on a crazy sleep shift on the last day. And so we were pretty worn out. So we took a little nap and then got ready after that for the deorbit burn, which is a pretty big emotional event when the big engine fires off-- Host: Yeah. Shane Kimbrough: And puts you on a trajectory to enter the Earth's atmosphere at the correct angle so that you actually make the landing site and make sure the vehicle's pointed in the right direction so you don't burn up when you're coming through the atmosphere. So that's obviously a plus. Host: So you didn't really feel the deorbit burn, right? You mainly felt the reentry? Is that what-- Shane Kimbrough: You do feel the deorbit burn-- Host: Oh. Shane Kimbrough: Because the engine kicks in and it's, you know, it's kind of like a kick in the pants, and you're thrown back in your seat. Host: Oh, wow. Shane Kimbrough: And it, you know, lasts I think about a couple minutes. So, you know, it's a sustained kind of pulse, and-- Host: You feel it that whole time, right? Shane Kimbrough: Yeah, you're feeling it. I mean, initially, you feel it a little more, and then you get used to it. Host: Right, right. Shane Kimbrough: And so then you're kind of getting ready to come back through the atmosphere, then separation of our descent module in the [inaudible], the habitation compartment happens. That's kind of like just an explosion, right. [laughs] So you feel it. You hear it. You see things flying by the windows from the other module that just came apart. So that's pretty interesting. Host: Yeah, not a boring ride. Shane Kimbrough: No, [laughs] not a boring ride. And then, we're kind of getting ready for the next big event. There's always, I mean, four or five big events along the way. The next one was parachute opening. Of course, after you started pulling, you're feeling the effects of gravity, all right. So we were pulling and we ended up pulling them 4.3 g's I think. So we felt like 4.3 times your body weight. Host: Wow. Shane Kimbrough: Which, after microgravity, felt like about 20 times your body weight. Host: Yeah. Shane Kimbrough: And so that built up, and we kind of just felt it building. We're watching the meter go up, and, man, I was like, wow, that's a lot. And then, right after that, the parachute, you know, started coming out, and that was really an emotional event because it's really dynamic, [laughs] I guess is the best word. And it kind of throws you around really drastically four or five times, and, you know, it's completely normal. But until you go through it the first time, which is my first experience, I was like, there's no way this can be normal. Host: Yeah. [laughs] Shane Kimbrough: But it is, and that's the way they do it, and it's just the parachute coming out and getting set up and the risers getting in the right position. And then, once that's done and then it's kind of a peaceful ride until you crush into the ground. Host: Yeah, yeah. [laughter] Okay, so the swinging back and forth, how would you compare that? Is it -- I'm thinking of an amusement park ride, right. It's got to be more intense than that, right? Shane Kimbrough: It is, but, you know, I don't know if there's one out there that just really slams you to the right [laughs] and slams you to the left, and you do that five or six times, you know, in a -- you know, I can't think of one that does that, but that's what it was like. I couldn't believe it. Shane Kimbrough: Yeah. Host: I guess that's why they, you know, they kind of strap you into that thing real tight, right, because you're-- Shane Kimbrough: Right. Host: Getting bounced and kicked in, like, all-- Shane Kimbrough: Exactly, yeah. Host: Directions. Shane Kimbrough: So as we come in, you start, the advice I got was as soon as you start feeling the g-force, start pulling on your straps as much as you can to really get you down into that seat-- Host: Yeah. Shane Kimbrough: So that you're not just secured but, you know, getting ready for the impact of the landing as well. Host: So is it fair to say that that landing was the hardest impact, probably? Shane Kimbrough: Oh, yeah. [laughs] Yeah. No doubt. Host: How did that feel? Shane Kimbrough: it was, you know, I've heard it called like, it's like a really bad car crash, and now I can confirm that that is accurate. Host: Wow. Shane Kimbrough: So you hit just really hard. And in our case, we hit twice really hard, so. Host: Oh. [laughs] And then, you roll around, right? Shane Kimbrough: And then, we rolled some more too just for added effect, so. Host: And then, you said, I remember you saying, because we did it in like a bunch of other events before this, but you said, like, you were in a position where you were just kind of dangling a little bit, right? Shane Kimbrough: Yeah, so I was kind of on-- Host: You were-- Shane Kimbrough: Top looking down at the ground, but-- Host: Yeah. Shane Kimbrough: In that case, I was hanging from my straps. Host: Wow. Shane Kimbrough: Really uncomfortable feeling for about five minutes, five to ten minutes until they could get there and roll the vehicle kind of to the normal position. Host: Oh, that's it. Just five to ten minutes, and then they were there. Shane Kimbrough: Yeah. It was very likely we had perfect weather that day. The search and rescue forces saw us the whole time. And really, right after the parachute opened, they tracked us all the way to the ground, so they were right there-- Host: Wow. Shane Kimbrough: In about ten minutes and got us out pretty quickly. Host: So when that door opened and they pulled you out, what was that feeling? Was it relief or was it just more of the, you know, just here's the next step kind of thing? Or, like, describe those emotions. Shane Kimbrough: Yeah, so the hatch, they opened the hatch, the search and rescue forces. And they're familiar faces from our training in Star City, Russia. I mean, they're Russian-- Host: Yeah. Shane Kimbrough: Folks. But it was nice to see their smiling faces. And then, I saw my flight sergeant from NASA and the Chief Astronaut Cassidy right there as well. So, you know, we were all smiles and waving. We all felt great at the time. And getting out is very challenging because it is so small, like we were talking about earlier. Host: Right. Shane Kimbrough: But they have to help you out. You can't get out on your own for gravity for one, and then it's just too tight and too small. You can't even really get to unstrap yourself. They have to get in there. It's that tight. Host: Wow. Shane Kimbrough: Like, you can't move your hands enough to unstrap most of your straps, so they get in there and help you out doing that as well as pulling you out of the vehicle. Host: Yeah. So okay, when you first, you know, you're pulled out of the capsule. You have fresh air, familiar faces. Obviously, that's a great moment, but so now you're kind of, you're back on Earth. You can feel it, right? What's, how are you feeling -- do you feel sick? Do you feel, is it mostly happy? Is there overwhelming feelings? What's going on? Shane Kimbrough: I think people have felt all those things you've mentioned. [laughs] I really felt great. I love smelling that fresh desert air. It was kind of like a 60-degree day in Kazakhstan. Feels beautiful. The wind was blowing. It was just awesome to have that sensation of nature again for me. And then, just seeing friendly faces and knowing I was going to get to talk to my family pretty soon after that was pretty special. Host: Yeah, that's amazing. What was the, so what was the main thing you noticed about the way your body was adjusting to life back on Earth? Shane Kimbrough: Well, to not move your head around is great advice, I guess. [laughs] Yeah, because that really provokes some folks to get sick, so-- Host: Okay. Shane Kimbrough: I really try to keep my head focused straight ahead. If anybody was talking to me, I would make them come right in front of me so I didn't have to kind of, because the natural tendency is to just look at them, right, but that really gets your-- Host: Yeah. Shane Kimbrough: Inner ear spinning up pretty well and-- Host: It must've been hard because there's a lot happening, right? People are-- Shane Kimbrough: There is. Host: All over. Yeah. [laughs] Yeah. Shane Kimbrough: So I heard people to my side, and I was, I just told them, "Hey, come right in front of me so I can see you [laughter] because I'm not going to turn my head." Host: Yeah, exactly. So-- Shane Kimbrough: And it seemed to pay off, so. Host: Yeah. Well, okay, so besides feeling sick, were you weak, like are, can you move around, or what was the-- Shane Kimbrough: You can move around a little bit. Host: Okay. Shane Kimbrough: They were carrying us. You know, I wasn't walking anywhere at the time, and they had people that carried us to where we were sitting there for a while. And then, after that, they carried us to the medical tent. But once we got in there, then it was a bunch of testing, and walking, and with your eyes closed and open, and just crazy things. And, [laughs] you know, just trying to-- Host: You just don't get a break. Shane Kimbrough: See where you're at. [laughter] Host: You just don't get a break. And then, they throw you-- Shane Kimbrough: Yeah. Host: On, what is it? To get a helicopter, and then the helicopter-- Shane Kimbrough: Yeah. Host: To a plane. Shane Kimbrough: Right. Host: You're off to Houston. Shane Kimbrough: Exactly. Host: Did you -- I'm guessing you slept on the plane, right? Shane Kimbrough: I did. I slept-- Host: Yeah. Shane Kimbrough: Really well on the plane, so it was good. [laughter] Host: I probably should've start off this -- I just realized -- but how are you feeling now? Shane Kimbrough: I'm feeling, yeah, I'm feeling really well compared to what I thought I'd be feeling at this point. It's only two days after I landed, like you mentioned earlier, and I really feel great. I had a great workout today, which I think really made me feel better. Host: Oh, wow. You're right back into it. Shane Kimbrough: Yeah, so we got about a 45-day program of working out and getting you rehabilitated, back to your full strength. Host: Okay. Shane Kimbrough: But it should only take maybe a week or so to get there, and then from there, we'll just build on whatever strength I have. Host: All right. All right, well, one more question, then I'll let you go. What was the first thing you ate when you got back here? Shane Kimbrough: [laughs] A lot of people are asking me that, and [laughs] it's a really boring answer, but it was a banana-- Host: Oh. Shane Kimbrough: Because that's something [laughs] I hadn't had in-- Host: A banana. Shane Kimbrough: A while. I was really wanting some fruit, and-- Host: That's true. It's not, yeah. Shane Kimbrough: I had a banana and an apple and had a bunch of those on the plane. [laughs] Host: Okay, so once you're -- how about this? -- once you're well enough, what's the first thing you're-- Shane Kimbrough: Yeah. Host: Going to eat? Shane Kimbrough: I think we're going to do some Italian tonight, which I've been thinking about. Host: Oh. Shane Kimbrough: So that's good. And then, Mexican probably here in the next few days as well, so. Host: All right. All right. >> It'll be good. Host: Definitely two good ones. Well, Shane, thank you for spending these couple minutes with me. Shane Kimbrough: My pleasure. Host: Thanks. Shane Kimbrough: Thanks, Gary. Host: Cool. [ Music ] Host: All right. Producer Alex, we're going to have to work on that wormhole sound effect. Come on. That was quite a ride. I mean, I was, [laughs] I honestly felt sick just listening to the way that he was going down. But there was a lot going on for every step of the way, so, I mean, first off, you know, what are those changes that he was talking about that makes him feel so, you know, so off when he lands on the ground? John Charles: The human body goes through many changes in weightlessness and the rest of spaceflight. I'm always interested most in weightlessness. I don't like the term microgravity. I think that's unnecessarily accurate. Host: There's a lot of synonyms, or syllables. John Charles: It's, yeah, a lot of syllables too. [laughs] But the weightlessness has profound effects, and I like to say that it's evolutionarily unanticipated. There's nothing that has ever happened to us in our lives and in all of the lives of everybody that lived before us, all the way back to as far as you want to go, that is weightlessness. Now, even floating in water is not weightlessness because you're still subject to gravity. The parts of your body that are denser go to the bottom and the parts of your body that are lighter float to the top, and that's true even in the vestibular system. The organs of balance he was talking about. Being dizzy. Those are not weightless, even underwater. The only time they're weightless is if you fall off a cliff, and then the effect is very short lived. Host: Right. John Charles: You don't get a chance to enjoy it very much. Host: Right. John Charles: So this is a real opportunity to, for the body to experience something that it's never experienced before ever, and not surprisingly, there are changes that occur in the body, and the changes might be summarized by the concept that the body economizes its metabolic energy. It doesn't waste energy supporting metabolic processes it doesn't think it needs. And nobody, you can't tell your body, hang on to that because you're going to need it eventually. The body doesn't talk to you in that sense. The body responds -- and by this, I mean the autonomic processes, the physiological processes -- respond to the environment that they have seen recently and are seeing at the moment. So as far as the body is concerned, gravity went away and it's never coming back. And so what do I need to do to be more effective metabolically in the environment that I will see forever? Host: It's just the body adapting to a new environment. John Charles: It's to a new environment. And luckily, the body adapts nicely to the weightless environment-- Host: Right. John Charles: Because it really is sort of a step down. It's less hard to do almost everything metabolically in weightlessness, and the body doesn't know that you're going back to Earth with gravity, so you have to fool the body to get back to, to get ready to go back to Earth. So you go through the changes of weightlessness, and these metabolic efficiencies I'm talking about include not maintaining bone strength. You don't need bone strength in weightlessness, and the body says, great, I'm not going to spend metabolic energy on that anymore. I'm going to dedicate it to something else. Host: Right. John Charles: You don't need muscle strength. You don't need cardiovascular strength so much. You don't need all of the intricate understanding of how to respond to gravity. You don't need to keep track of where all your joints are, your limbs, and all that kind of stuff. Host: Because all of that is gone in the weightless environment. John Charles: That's right. Host: It's just, you don't need your bones because you're not pressed up against anything. John Charles: You're not-- Host: You're just floating. John Charles: You're not supporting yourself anymore. Host: Right. John Charles: There is a residual bone strength, a residual bone volume or density that you will probably plateau at. If you stay in space forever, you will never become like the guys were in WALL-E when they had no bones. Host: [laughs] Yeah. John Charles: Just the big blobs of jelly. Host: That's right. John Charles: That would never happen. You probably, based on other studies and clinical experience, you'd probably lose up to 40% of your bone mass eventually. That is after years, and years, and years. Host: Wow. John Charles: So you, I mean, even so-- Host: Is this saying that you're not working out during those years? John Charles: Yeah, assuming you're just weightless. Host: Assuming you're just weightless. John Charles: Assuming you're just weightless and not working out, that's right. Host: Okay. John Charles: Which would be I think my preferred lifestyle. [laughs] I'd like to be weightless and not working out. But that, see, Gary, that's the answer, though, is the way we fool the body or don't fool the body. We just change the conditions is by working out. So the astronauts work out two hours a day every day, including resistive exercise, my favorite. I call that weight lifting in weightlessness. Host: Right. John Charles: And that's all done with hydraulics and computers. And then, or aerobic training -- exercising on treadmills, and bicycles, and maybe a rowing machine someday. And what that does is put a load on the bones, and the muscles, and the cardiovascular system, not the vestibular system, not the organs of balance, but all the other systems mimicking the absence or the effect of gravity, which is then absent in that environment. Host: So that's, so they're doing those you said aerobic and resistive. So that's the, I guess like you said, though, in space, the weight-lifting machine-- John Charles: Right. Host: Sort of with hydraulics-- John Charles: Right. Host: And that simulates weight lifting. And then, you also have aerobic exercise, which is the treadmill and the bicycle. John Charles: The bicycle. Host: So you have to do this I believe two and a half hours every single day-- John Charles: Yeah. Host: In order to maintain everything? John Charles: Right. And that's a total of two plus hours a day. That includes breakdown, and setup, and changing your clothes, and all that stuff. So you do-- Host: Oh, yeah. John Charles: You know, multiple tens of minutes at each. Host: I see. John Charles: And different exercises on different days. And I think one day is actually a free form. You can do whatever you want. But, you know, the other days are fairly prescribed. But what that does is put a load on the bones, and the muscles, and the cardiovascular system, and other organs as if they were doing something against gravity. It's not the same, but it's close. Host: So that's the way that you're saying you're tricking your body-- John Charles: You're tricking your body. Host: Into thinking that, you know, you don't need, you still need to maintain the muscles. Hold on. John Charles: Right. Host: Stop. You know. John Charles: You're maintaining them for something else. You're maintaining them for exercise and not for fighting against gravity. Host: Right. John Charles: But it has the beneficial effect in many cases of being appropriate for gravity. And in fact, the resistive exercises that we're doing now seem to minimize the loss of bone structure that occurs in weightlessness that has been seen on previous missions. So the Advanced Resistive Exercise Device, the ARED, may well be the way that we protect bones and muscles in the future on Mars missions. Host: Oh. John Charles: It may be that we're able to go on really long missions without losing much calcium and without changing the structure very much of the bones. And it's not the loss of calcium per se that's the problem. It's where the calcium comes out of. The bones are developed in everybody whilst you're growing up. Host: Right. John Charles: You're, when you're growing up, you know, you're, first, you're born with a skeleton, and then you spend the first 18 years of your life banging yourself around, and jumping up in trees and off of hillsides, and falling, and jumping, and running, and pulling, and lifting. And all that stuff shapes your body. Host: Yeah, and that's in childhood. John Charles: Right, and that, [laughs] well, I saw people do it. [laughs] Like I said, see previous comment. Host: Right, right. John Charles: But that shapes your body and gives you the structure you need to keep doing that for the rest of your life. And then, at some point, that, those structures, those facets are completed, and you can then go and do useful things with the body that you've built up over the first 18 plus years of your life. Host: Right. John Charles: So when you go into weightlessness, you start eating away at that in the absence of gravity, and if you come back to the Earth, you restore some of that, but you don't restore it the way it was originally. You restore it to the way it needs to be now, which means you don't go back inside the bones and reestablish the framework, the structure. And the bones actually have structure inside of them. The outside is called the cortex, and it's a thick layer. And then, on the inside are the trabeculae, and the trabeculae are like a framework. Think of a lattice work inside of your bones. And those, that lattice work is genetically engineered by you as you grow up to respond to the forces you're putting on bones. So it puts down calcium where the forces are the greatest and it doesn't put down calcium where the forces are not the greatest. But that's the structure you take with you for the remainder of your active life, unless you go into weightlessness. In which case, that obviously gets eroded gradually but persistently over the time in weightlessness. So your bones actually do lose calcium, do lose mass, bone mass, and you lose strength of the bones. Not, so far, not enough to cause you to fracture when you come back to the ground. There have been a couple of astronauts who have fractured bones in the post-flight period, and we have analyzed those, and they would've fractured their bones if they had never flown in space. They just caused an impact that broke bones, and that's just what happens. Host: They were trying to run up and down trees like their childhood days, right? John Charles: Well, they, yeah, nothing quite so [laughs] glamorous. One guy fell off of a stage after a public affairs presentation. He just-- Host: Oh no. John Charles: He didn't fall off. He tripped because there was something on the edge of the stage, so-- Host: Oh. John Charles: It was unavoidable whether he was an astronaut or not and whether he'd flown in space or not. Host: Right. John Charles: So we don't see bone-breaking episodes in astronauts that would not have broken their bones beforehand, but there's the risk that with even longer flights, longer than six months like Shane was on and longer than one year like Scott Kelly and Mikhail Kornienko were on, and perhaps, you know, two-and-a-half year Mars missions might be getting close to the threshold where you might start seeing a slight possibility, increased possibility of breaking bones under normal circumstances. Not during the mission, but after the mission when you're back on the Earth. You know, that's sort of, after 30 months, that's when you start getting close to that threshold. Host: So it has to do with the time that you're in the weightless environment? John Charles: It seems to be an ongoing process. And like I say, though, that process seems to be interrupted by the heavy resistive exercise. Host: Right. John Charles: So that sort of stretches that period out. So you're not at risk if you keep doing your heavy resistive exercise. But that's an interesting question too, and you haven't asked me that one yet, but I'll go ahead and answer it because-- Host: [laughs] You were just reading my mind. John Charles: Yeah. That is, are we going to do resistive exercise on the Mars missions? And the answer is I hope so. Host: Right. John Charles: But we probably will not be using the ARED. The ARED is a very large device that takes up an entire module on the-- Host: Right. John Charles: Space Station. It's a node, which is, that's a module. And we don't have, probably will not have that kind of real estate, that kind of volume available for that kind of device. So right now, what the Human Research Program is doing is trying to understand which of the exercises on the ARED are the most effective in protecting which of the bone facets that are important to protect. And then, building a smaller device that'll just do those. A tailored, specialized device. So this is maybe an important point to make, and that is astronauts will go on missions and will suffer deficits -- deficits that we know how to protect against because we can't afford to protect against them within the limited constraints of a spaceship. So we will give them a device that gives them certain exercise capabilities to protect them against deficits that we think are the most important. But we may be allowing the rest of other aspects of the, say, the other aspects of the skeleton to go ahead and atrophy just because we don't have the flexibility and the resources to protect them against that. We don't think that's going to put them at an increased risk because they're not going to be doing things that will need those aspects on the skeleton, for example. Host: Right, so you've prioritized and you-- John Charles: We had to prioritize lots and lots of things when we start talking about a Mars mission. Host: Right. Yeah. No-- John Charles: I knew we wanted to talk about a Mars mission [laughs] because that's the only thing you talk to me about ever. Host: [laughs] Well, we were getting there. John Charles: Yeah. Host: I was taking baby steps. John Charles: Yeah. Host: And you just jump right there. John Charles: I did. I did. Host: [laughs] I guess, so how would the exercises, since we are on Mars now, how would the exercise work on Mars, you know, if you're talking about landing on -- would you kind of use sort of the same thing, or can you afford a different type of exercise? John Charles: Well, it's going to have to be tailored for the Mars environment, and for the Mars environment means both exercising at one-third of a g, or 38% of Earth's normal gravity -- we call that a third of a g -- on Mars. And also, being appropriate for the spacecraft that will land on Mars. And you raised a very important question. I hope you realized you raised it because it's an important question. Host: [inaudible] intentional. John Charles: And that is, that's, it's a matter of economics to get to Mars. First, you got to build a spaceship, and then you got to send it there with fuel. And fuel is the coin of the realm in space. It takes lots, and lots, and lots, and lots of fuel to get any place. And if you get there, then it takes even more fuel to slow you down and land safely. So everything on the surface of Mars will be mass constrained and volume constrained because mass, volume requires mass. You know, if you build a small room, it's got less mass than a big room. So we are going to be focusing on not only what we can put into the Mars transit vehicle, which will be constrained by the volume of the vehicle, but also what we can land on Mars, which will be constrained by the volume of the lander and the mass capable of landing. So it may well be that we figure out, we hope we figure out a way to use that one-third of a g on Mars as a way to supplement some of the exercise that they would normally be doing in their mini-gym inside the Mars lander or the Mars habitat. Host: Right, so when you're thinking about a Mars mission, it kind of goes back to that idea of prioritizing, right. So just as you're going to prioritize which parts of the body are the most sensitive-- John Charles: Right. Host: The most important for you to maintain, when you're sending stuff to Mars, you got to prioritize which things are the most important things to bring, to send, and make sure they're really small, and light, and don't take up a lot of space. John Charles: Small, and light, and don't take up a lot of space, and don't take a lot of energy, don't take a lot of mass, power, volume, which are the-- Host: Right. John Charles: Important constraints of a spaceship. And just think, we started talking about this because I was trying to make the point that Shane's body is not back to normal yet still. It's, his bones are going to take months to get back to normal. But other organ systems may respond more quickly. Host: But they will get back to normal? His, is the months? John Charles: See, here's a metaphysical question -- what does normal mean in a case like this? Because your bone changes normally over the course of your lifetime, including over every six months. You know, he was gone for six months. His bone was going to be atrophying a little bit anyhow. Host: Right. John Charles: So we're not going to get him back to what he was before flight. And why would we? Because he wouldn't be at that condition now after his landing if he'd just been walking around the Earth for six months. Our goal is to get him back to where they need to be to live a full, happy, functional life here on Earth. But it's, you can't, you know, you can't go home again. You can't go back to your old skeleton again. It just, this is, things are different [laughs] with time in life, and that's doubly true for time spent in space. Host: Yeah. It doesn't matter. You're always going to, just going to get older. Time's-- >> You're going to get older. Host: Just going to go forward. John Charles: That's right. Host: But you, I guess, you know, bones are not the only thing you have to think about, right? You have to-- John Charles: That's correct. Host: Think about a lot of other things. Shane mentioned, you know, when he landed and they pulled him out, he couldn't even turn his head. He was extremely dizzy. John Charles: And see, I think this is the other extreme. The bones are the, some of the slowest to respond in spaceflight and some of the slowest to respond post flight during the recovery back on Earth, but the vestibular system is probably the fastest responder. The vestibular system is the organ system of balance, and it allows us to stay upright. We are constantly making adjustments in our bones and our muscles and the way they're lining our, lining us up. I mean, the old illustration is imagine balancing a broomstick. Remember broomsticks? We used to have brooms and broomsticks. And imagine balancing a broomstick upright on your, on the palm of your hand and all the adjustments you have to make to keep that upright. Host: Right. John Charles: That's how it is when you're walking. When you're walking and standing on one foot or even standing on two feet, your body is constantly adjusting its center of balance and its center of mass to stay over the center of pressure of the feet so you can stay upright. And that all requires sensors in the skin, sensors in the soles of the feet, sensors that detect the angles between the ankle, and the shinbone, and all the other bones, and the organs of balance inside the inner ear. And Gary, even though we're on a podcast, I am automatically pointing at my ears because the organs of balance are behind the inner ears. Host: I can see. John Charles: Yeah. Host: [laughs] But I guess no one else can. John Charles: Nobody else can. [laughs] But this organ system is exquisitely tuned to respond to motion and to respond to gravity. There are parts of it that detect how you move your head, and now I'm twisting my head left and right because that causes a sensation in my inner ear, which then is, at a most simple case, is translated to my eyeballs. So my eyes counteract the motion on my head so I can keep continuing to look at you while we're talking. But there are other organs that detect my tilting my head left and right, and those are the balance. So those are the otoliths. The other ones are the semicircular canals. But the otoliths, the otolith is ear stone, oto-lith. Host: Okay. John Charles: And those are little stones inside little sacs of fluid inside your head which detect which way down is. And those are the ones that are the most immediately affected by spaceflight and weightlessness because if your whole existence is predicated on detecting down and somebody takes away down, then what do you do? And that's sort of how the vestibular system responds to weightlessness is it spends a lot of time the first several hours or several days saying, oh my God. Oh my God. Oh my God. My only job is to detect down and there is no down. What do I do now? Now, I'm built, you know, the organs of balance are built to detect motion and to detect directions of acceleration, so they may get more sensitive. In fact, the little otoliths in your ears might become bigger. They might accrete more of the mineral that they're made of because they, they're sure there's a down there someplace and that if they could only get heavier, they might be able to detect it again. Host: And this is over the first couple days of the spaceflight? John Charles: Over the, it's over the course of the spaceflight. Host: Oh, over the -- wow. John Charles: Over the course of the spaceflight. Over the course of the first few days -- thank you for bringing me back to the point at hand -- [laughs] over the course of the first few days, essentially the brain says, you know what? You guys are just making gibberish. You're not making any sense anymore. I'm going to start ignoring you. Now, the brain doesn't actually use words. It just sort of economizes the metabolic energy. It says, I'm not going to put so much metabolic energy into the nerves that come from the vestibular system because-- Host: Right. John Charles: I'm just getting gibberish from there and it just, it makes my, the stomach part of me sick. Let's just not pay attention so much to that anymore. And in fact, on Skylab, the American space station in the 1970's, when there was a rotating chair onboard specifically to see how often we could make astronauts sick in spaceflight -- rotating chairs are good ways to make people sick. If you rotate them and ask them to move their heads while they're rotating, that's a great way to be sick. Host: Oh, yeah. I remember those chairs. John Charles: Turns out after a few days in weightlessness, astronauts couldn't be made sick anymore by moving their heads while they were rotating because the-- Host: Yeah. John Charles: Organs of balance had adapted and also because the stimuli were different. Host: I've seen that video of Tim Peake, where I think it was Tim Peake and Tim Kopra, when they were both on the International Space Station-- John Charles: Yeah. Host: Kopra took Peake and just spun him around really, really, really fast-- John Charles: Yep. Host: And then stopped him suddenly. And Peake had like one moment where he stopped suddenly where, I mean, the whole time he was spinning, he didn't feel a thing. John Charles: Yeah. Host: And then, he stopped suddenly. He's like, "Okay, I'm dizzy for a second." And now he's good. John Charles: It's gone. Host: Yeah. John Charles: So there are quick responses, but as I say, you know, the organs of balance, vestibular system continue to, like I say, try to find gravity. And so they may actually increase the mass of the little stones inside your inner ears. And that's kind of an interesting novelty that nobody's figured out yet whether, what the functional -- operational, I should say -- significance -- functionally, we know what it means -- but operationally, what does it mean in terms of your ability to stand upright after you land on Mars? Or things like that. So there's lots of more, lots of research on, some topics for research that we can do in that domain. But the point I was trying to make originally is that this is a quick-responding organ system. Then, slightly slower will be the organs of your cardiovascular system. And those are all fluid based in the sense that they, you're a big, pressurized bag of fluid. Nothing personal, but all of us are. [laughs] And our goal is to stay pressurized by the function of our heart so that the blood can then perfuse the brain and also the blood pressure we carry around with us, 120/80, when the doctor does your blood pressure, tells you, yes, 120/80. Host: That's a good one. John Charles: That's the pressure that you need to get through the muscles when you're exercising. The, when your muscles are exercising, they're constricting and contracting. They're squeezing down the blood vessels. It takes a certain amount of blood pressure to push through there to deliver the nutrients that the muscles need to continue exercising. That's where your 120/80 comes from. And you have to continue building that pressure up. But in weightlessness, you're not exercising so much anymore. You're floating freely. You're relaxing, and your blood vessels are dilating, and your pressure, you'd actually lose blood volume in space. You may lose about a liter of blood in space. Host: Wow. John Charles: You may actually lose, that's about a blood donation, about the same amount as they take out of you when you donate blood, half a liter or a liter. Host: Huh. John Charles: Yeah, that's because the body's, the fluid distribution builds into it an assumption that a lot of your fluid is going to be down in your lower limbs because of gravity, and your lower limbs have a lot of veins, which are very floppy and good places to sequester extra fluid that you don't need, extra blood you don't need. And in weightlessness, that fluid is all shifted into the upper direction, and it's-- Host: Oh. John Charles: There's not a lot of extra venous volume in the upper part of the body, and so the body says, aha, I've got a, I've got too much fluid onboard. I know what to do in a case like this. Decrease thirst, increase urination, you know, eliminate fluid elsewhere, shift it into other parts of the body, which has the effect of causing your body to lose blood volume over the course of the first few weeks in spaceflight. Host: That was going to be my question. John Charles: Yeah. Host: Where does that liter go? Okay. John Charles: Liter goes out, becomes tomorrow's coffee. Host: Yeah. [laughs] John Charles: You remember the old analogy about the water recycling system. Host: That's right. John Charles: So that fluid volume is appropriate for your time in weightlessness. And again, one of those tricks that you pull on your body is that you come back to the Earth after your time in weightlessness and suddenly that fluid drains back down to the lower part of the body. And then, suddenly, the upper part of the body is volume deprived, and that's when you may feel a little bit light headed, a little bit weak. Astronauts wear compression garments in the lower body -- in the legs, especially -- to squeeze to make sure the fluid stays up in the upper part of the body and not pooling in the lower part of the body. Shane was wearing those compression garments that are called Cantaver [phonetic] garments. That's the Russian name for Cantaver. [laughs] And it-- Host: Nice translation. John Charles: Yeah. I'm good at that. But that, those are very effective techniques, and we are, we have other capabilities like that as well. But the point is during, while he wasn't being sensitive to emotion by not turning his head very much, he was also, his body was functioning to keep the blood flowing to the upper part of his body through his brain so he could continue to function normally. That's all part of the early re-adaptation process as well. Host: That's right. John Charles: So the vestibular system is quick responding. The cardiovascular system is slightly slower. Along the way, you lose muscle mass because you're not hefting your body mass around, and they have to rebuild that when you come back. And then, out there at the, sort of the tail end is your skeleton. What we haven't talked about before, yet, though, are things like your radiation tolerance, or radiation exposure, I should say. Host: That's right. John Charles: That doesn't plateau. That doesn't decrease. That doesn't accommodate because you keep getting exposed to radiation, and radiation has a cumulative effect. The more you-- Host: As long as you're in space-- John Charles: As long as you're in spaceflight. So that's an ongoing issue, and that's something we will have to deal with going to Mars because you're exposed to even more radiation when you leave Earth's magnetic field and are-- Host: Right. John Charles: Exposed to the deep-space radiation. And then, the other aspects, of course, are the psychological aspects of spaceflight. And if you think what I've described to you before is complicated, you ain't seen nothing yet because the psychology [laughs] is one of the most self-regulating and self-protecting let's call it organ system that we have until it's not anymore. And so you adapt, you accommodate, you adjust. All those A words are the way that your [laughs] psychological aspects function in normal, everyday life and especially in spaceflight. Host: Yeah. John Charles: But you're exposed to stresses that are the most unique that anybody's ever been exposed to in spaceflight. And if we're talking about a Mars mission, we're talking about let's call it two and a half years just you and three other people face to face in the volume of a couple of Space Station modules maybe with the pressure and the eyes of the world on you to make sure you, to wonder if you succeed. So there's no pressure, obviously. And the, nobody can help you when you're on your way to Mars. At least, they can't help you immediately. There's going to be, when you get to Mars, you may be eight minutes away from Earth by radio. Host: Right. John Charles: At the midpoint of your stay on Mars, you might be 40 minutes away, 20 minutes away one way by radio. Host: Yeah. John Charles: So if you have a problem and it takes longer than, it takes less time than 20 minutes to fully express itself, and you don't know what you're doing, then you've got a big problem. Host: That was one thing Shane said. He said, five minute, he landed. Five minutes, and everyone was, you know, taking him out of the capsule. John Charles: That's right. Host: And you're right. You're not going to have any-- John Charles: That's right. Host: Not only no help, but it's going to be a while until actually someone talks to you. John Charles: I like to paint a picture for people, and that is if you're the first person on Mars, you're climbing down the ladder, and you stumble and fall face first into the Mars dust, [laughs] the bad news is that everybody on Earth will see it because they're all going to be watching the live stream. Host: Of course. John Charles: But the good news is it'll be 20 minutes before they see it. [laughs] So you've got a few minutes of relief before you have to explain to the entire universe how you stumbled your, for your first step on Mars. Host: [laughs] That would be pretty cool if that was the actual video of-- John Charles: Yeah. Host: The first person stepping on Mars. [laughs] So obviously, you know, you have to be thinking about, you know, this is, obviously, you are thinking about, you know, this is kind of what that's going to look like if someone's going to land on Mars. You know, what are we doing to sort of get them ready for that? One of the things I think, I'm pretty sure Shane mentioned was they sat him in the seat and, for a while, and then they took him right to a tent and started doing some field tests on him. John Charles: Yes, they're, exactly, and that's exactly what we called it. We call it the field test. It is, it's one of our Human Research Program investigations. It's a joint investigation by the U.S. and the Russians. The U.S. and Russian investigators Millard Reschke and Inessa Kozlovskaya are very longtime investigators, and they both have been anxious to do this kind of research on the adjustments of the sensorimotor system and the neurovestibular system to gravity after a long-duration spaceflight. We started doing this a few years ago. Chris Cassidy I think was the, actually the first guy to do it on his Soyuz landing. Host: Oh. John Charles: And we've been doing it pretty consistently since then to try and build up a database of responses so we know what an average, and, you know, what the statistical mean is, and what the variation is. Host: Nice sample size. John Charles: Nice sample size. Host: Right. John Charles: And it's also very dramatic, and it's also, it's a, an important set of things to do. But what it does briefly is after they're extracted from their Soyuz -- and you heard Shane talk about how they got out of the Soyuz with a lot of assistance. Nobody going to help you on Mars. Your vehicle has to be designed appropriately for you to get out on your own. Then, they set him in a chaise lounge for a little bit and have a brief public affairs event there on the steps of Kazakhstan, and that's a good chance for them to catch their breath. And then, they're carried, not walked, but they're carried into the medical tent. And inside the medical tent, in privacy because of human research concerns-- Host: Right, makes sense. John Charles: They are unsuited -- that is, their space suits are taken off -- and then, then if they volunteered for this investigation, they go through a stylized set of motions. And they start off with being seated in a chair and just being asked to stand upright and stand quietly for 30 seconds or so. Host: And that must be hard, though, right? John Charles: That's a substantial stress, a substantial [inaudible]. Host: Yeah. John Charles: Sonny Carter back on STS-33 I think it was said -- and that was after a five-day flight -- said the hardest thing he had to do on his spaceflight was stand up for the first time after a spaceflight out of the chair in the shuttle. Host: Wow. John Charles: So that was after just a few days. Now, this is after six months or so of weightlessness. Host: Right. John Charles: So that's the stress. We're watching their blood pressure, their heart rate, as well as their balance. And then, sort of to add insult to injury, one of the early things we do then is to lay them on the floor in the face down, in a prone position, and then ask them to stand up again. And it's, to mimic, it's called recovery from a fall. So the idea is that they have stumbled on Mars or they've stumbled on the Earth and they find themselves face down in the red dust on Mars like I've mentioned before. How long does it take to get back up again? And that we can quantify how long it takes them to stand up, to go through all the complicated motions of getting up on your hands, and getting up on your knees, and then finding a way to balance yourself and get back up. That's a very integrated physiological and, or musculoskeletal activity, and it's, it can be quantified. And then, once they've got them standing up again, and I always haste to add that no astronauts are actually pushed over. They're asked to lay down gently and then stand up. Host: [laughs] That's funny because that would be very rude. John Charles: That would be another good video. [laughs] But then, we make them walk an obstacle course to see if they can do it. And the obstacle course is actually, as Shane described, walking in a straight line with your eyes closed, or with your eyes open and then with your eyes closed. And sometimes, you know, eyes closed, you veer because you're using the, your visual system is your dominant way to orient yourself in the absence of a functional vestibular system and in the absence of a fairly relaxed set of somatosensory sensors. Those are the sensors that detect pressure on the bottom of your feet and at the angles of the joints, you know -- your ankle angles, and your elbow angles, and things like that. So walking with eyes open is always a challenge. Walking with eyes closed is almost always impossible because you veer immediately left or right because you just can't orient yourself in the absence of any inputs. And the inputs you're receiving are those that your brain has decided six months ago to ignore, and inputs that it wanted us, wanted to keep you've now deprived yourself of because your eyes are closed. So there's a little bit of a stressor there. And then, there are other things that we ask them to do as they sort of gradually move through this set of activities -- moving heavy masses back and forth as if they were unpacking a Mars lander and getting things set up on the surface of Mars, and, you know, just a bunch of generalized things like that involving motions, bending, twisting, standing still, you know, things like that. So-- Host: So how long does that usually take? John Charles: It's about 45 minutes-- Host: Wow. John Charles: In the tent, and that's only a subset. When they get back to Houston, there's a much longer set of measure, of activities they go through, and that'll be 24 hours after landing. Host: Right. John Charles: But we also test them in the airport in Karaganda, which is where the helicopter takes them after they land. Host: Right. John Charles: Or we test them in the airport either in Norway or in Scotland, depending on where the jet lands to refuel on the way-- Host: Their layover, right. John Charles: On the way back. Their layover. Host: Yeah. John Charles: So that gives us, you know, minutes, and hours, and then a day of adaptation. And then, we watch them for several days post flight up to potentially even several weeks post flight to track their full recovery back to normal. And this is specifically to quantify the responses, the re-accommodation and re-adaptation back to gravity so engineers can design habitats and landers for Mars missions, and they'll know what capabilities astronauts will have to design around. Host: Right. John Charles: Now, smart fellow that you are, you're going to say, but John, you already said that Mars has only one-third of a g, and here we are making them do all this stuff at one g. Host: Again, you're reading my mind. [laughs] John Charles: We've worked together so much, I can anticipate your, almost your next thought. But the deal is, yes, we are making them do it at one g when normally on Mars they'd be at one-third of a g. All we've got is one g, and this is the closest we can get to that situation, so we have to-- Host: Right. John Charles: Make the appropriate adjustments, if we think it's necessary, to compensate for the fractional gravity. But right now, in answer to your next question, we don't have any information on what fractional gravity does. And so we just have to assume that it will be as unpleasant, uncomfortable, difficult as one g is. And then, once we get experience at fractional gravity, like if we go to the Moon and get one-sixth of a g experience or if we land on Mars, and do it a few times, and say, you know what? That was not as hard as we said it was going to be. It's going to be easier here at one-third of a g. We can make the appropriate adjustments. Host: Right. There's a lot deeper of a story here, I can tell. John Charles: Yeah. [laughs] Host: There's a lot of different directions we can go, but I'm going to ask one more question, and then we're going to let you go. So, you know, you have all these field tests, and you're kind of preparing for what, you know, what we have to do in order to make a Mars mission work. So I do have one, like, theoretical question for you: In a perfect world, if you were to land on Mars, what would you want that to look like? I'm guessing, I mean, can it be as simple as they land on Mars and they're good? They get out of the capsule. Or is there, you know, is there other things that we are going to have to sacrifice based on the knowledge we have now to make that as easy as possible? John Charles: I think the answer is going to be yes and yes. Host: Awesome. John Charles: I think astronauts come in varieties just like other people do, and some people will have problems accommodating, adjusting, adapting, and others will not. Some folks are going to be able to land on Mars, and bounce right up, and feel like they want to go to work. We're probably going to insist that the landing vehicle be able to accommodate them for a couple of days. Host: I see. John Charles: Because we don't want to bet that they're all going to be perfect, they're all going to be bulletproof. And by perfect, I mean in this particular regard. Because they're all going to have, they're all going to be perfect in some way. It's not just, you know, the, not just the '70's kids. [laughs] We're all perfect in some way, but they're all not going to be perfect at adjusting to Mars. There's going to be some that are slower, and some that are faster, and some that are sort of run of the mill. We have to accommodate all of them because you can't leave the guy behind that's not feeling the best, then go and start exploring Mars. Host: Right. John Charles: So the goal is to make the landing vehicle as lightweight as possible. Previous discussion about mass, and power, and volume. Host: Right. John Charles: Which means minimize the amount of mass that you dedicate to life support systems. You don't want to build a two-week life support system into the lander if you're only going to use it for a couple of days, then you're going to feel good enough to go out and then traipse across the desert to the habitat that's waiting for you with all the life support you can use inside of it. Host: Right. John Charles: But you don't want to carry excess life support, but you don't want to carry too little life support in case it turns out to be, just by the luck of the draw, you've got four people that are going to have a tough time readjusting, and-- Host: Yeah. John Charles: They don't want to get, put their space suits on and stumble across Mars face down into the dust, you know. Things like that. Host: Yeah [inaudible]. John Charles: So what I would like to see the landing on Mars look like is that the entire crew feels good, and it was the luck of the draw that we got four people that just turned out to feel good this time. They're, they understand the importance of the design of the habitat, of the lander, so they take their time getting suited up and making the excursion out. Maybe they, maybe we're clever on the first landing and we don't make them actually walk very much at all. We make them have a radio-controlled rover that deploys from the habitat, and comes over, and is waiting out their front door on the lander. And they get into that, and they drive off to the habitat, and they get in, and set up housekeeping instead of actually having to stress themselves for the first time in a six- or eight-month period of time after they transited to Mars. Host: That's a cool concept. Nice. John Charles: So, you know-- Host: Valet service. John Charles: Yeah, valet service. [laughs] And it might be even, may be even a self-driving car, so maybe Uber or-- Host: Yeah. [laughs] John Charles: Google's going to have something to say about it. Host: That's right. John Charles: And then, they gradually become accustomed to their environment on Mars so they can go to work on Mars. The habitat will have the gym, whatever it looks like, as well as the food, and the fresh water, and the fresh air. But the point of all this is not to cater to the astronauts. The goal is to make sure that the astronauts are, as I like to say, in the best condition of their lives when they land so they minimize the time they spend readapting-- Host: Right. John Charles: Because the Mars missions will be the most expensive undertakings humanity's ever embarked upon. Host: Sure. John Charles: And if we want to have a second, and a third, and a fourth, and a fifth one, the first one had better be productive. And the way to be productive is to be in good condition so you can get to work as quickly as possible, allowing for the accommodation time of a few days, or a week, or so, and then get to work, and show us why we sent you to Mars, and make those Nobel Prize winning discoveries on Mars so that Congress, and the parliaments of all the partner agencies, and everybody, all the taxpayers, think, yeah, that was a good thing. We want to do that some more. [laughs] We'll have more Mars missions and build up the flow to Mars and the infrastructure for Mars. So it's, it sounds like I'm altruistic, but Gary, you know me well enough to know that [laughs] I'm not altruistic. I want the astronauts to be in great condition when they land on Mars not just for themselves but for us too because if we have hopes of becoming a multi-planet society, our first emissaries to other planets will have to be, will have to demonstrate how productive we can be in other planets, and that's really the goal here. Host: John, I want you to lead the charge and lead us [laughs] all the way to Mars. John Charles: I'm not going to Mars, then. Host: You'll be the guy landing. [laughs] John Charles: I want to stay at home and cheer them on. Host: [laughs] Well, this was awesome. Thanks for coming on the show and talking about, you know, really analyzing what Shane was feeling and what, why we are doing what we're doing, you know, obviously for later missions and landing on Mars. So obviously, you know, there's something that, there's some stuff that Dr. Charles was not able to address today, so for those listening, if you want to know more or you have a suggestion on what we need to talk about, stay tuned until after the music to learn on where and how you can submit some ideas. So John, thank you so much for coming on the podcast. John Charles: Delighted. Thank you [inaudible]. Host: Glad to have you, and we'll probably have to have you again. John Charles: Okay. [ Laughs ] [ Music ] Host: Hey, thanks for sticking around. So I hope you enjoyed our talk with Dr. John Charles and Astronaut Shane Kimbrough. If you want to learn more about kind of all the things that specifically Dr. Charles talked about, there's, we actually have a website for that, per usual -- nasa.gov/hrp. This is the website for the Human Research Program, and you can learn about everything that they're studying there. All of these things that Dr. Charles was talking about -- the human body, bone density, even we have some stuff about the twin study that happened just actually a couple years ago now when Scott Kelly launched in 2015. So you can find all that information there. A lot of the research that's done and especially with Shane Kimbrough on the International Space Station was done up there on that orbiting complex. You can go to nasa.gov/iss to learn about the latest updates on the International Space Station -- all the latest blogs and scientific findings. We also have a lot of cool pictures that we like to put up on that website. On social media, we're very active. Facebook is the International Space Station. That's their Facebook page. On Twitter, we're @space, underscore, station. And on Instagram, it's @iss. If you want to submit an idea or you have a question about something that we talked about on the podcast, just use that hashtag #asknasa on your favorite platform. Doesn't matter. We'll check them all. And we'll make sure that we address it on one of the next podcasts that we do. And maybe we even will make a whole podcast out of, episode out of it. So this podcast was recorded on April 19th thanks to John Stoll and Eric Sparamin [phonetic] for helping to produce the show. Thanks again to Dr. John Charles and Shane Kimbrough for coming on the show. See you in 6.79 sols. Get it because the Mars? Okay. See you next time.

Temperature Regulation in Critical Salmon Habitat of the Middle Fork of the John Day River, Oregon.

NASA Astrophysics Data System (ADS)

Buskirk, B. A.; Selker, J. S.

2016-12-01

Flow and temperature within the Middle Fork of the John Day River, an arid Eastern Oregon river, is dominated primarily by contributions from groundwater fed tributaries. The hydrology of arid streams is an important metric for understanding the critical environment in which salmon spawn and salmonids reside. The regulation of temperature within these streams is considered the primary metric for survival rates of these fish. Since 2007 Oregon State University has conducted stream monitoring efforts on the Middle Fork of the John Day River at the Oxbow and Forrest Conservation Areas. These sites were chosen through collaborative effort with the Confederated Tribes of the Warm Springs Reservation of Oregon, who have been restoring remnant mining canals back to their natural sinuous river pattern. The John Day River is also one of the few undammed reaches in which salmon runs occur. Efforts have focused on fiber optic distributed temperature sensing (DTS), groundwater gradient, stream discharge, bed permeability, GPS location and stream bathymetry across the conservation sites. During the peak of summer, stream temperature exhibits a strong diurnal cycle ranging from 9° C to 23° C depending on the daily maximum observed within the reach. Salmon have been found to be sensitive to stream temperatures above 15° C and are unable to survive temperatures above 24° C (Bell et al, 1991). The synthesis of temperature and stream flow data we collected show that very little groundwater is contributing to flow and temperature in the main channel of our study site while tributaries provide a constant, typically 0.5 to 2° C cooler, input of water to the main river channel and significant source of flow (0.01 - 0.1 m3/s). Due to the minimal rain fall in this arid environment, snow melt infiltration is likely the primary annual source of recharge into the head waters of the tributaries while also providing temperature regulation through input of near 0° C water. This cold water input from tributaries in addition to bank overhanging sedge grass provide cool safe zones for the young and mature fish during peak summer temperatures.

Observational and mechanistic data suggest a role for vitamin D in childhood asthma. However, subsequent interventional trials have been inconsistent. We aimed to assess the effect of 15 weeks of vitamin D3 supplementation compared with placebo (PL) in Irish children with asthma. We conducted a double-blind, randomized, PL-controlled trial of vitamin D supplementation (2000 IU/day) in 44 urban, Caucasian children at high latitude. Assessments were completed at baseline and after 15 weeks of supplementation. Outcome measures were lung function, subjective asthma control and biochemical parameters of total vitamin D, allergy, immunity, airway inflammation, and systemic inflammation. Finally, parents/guardians completed a weekly diary during the trial. There was no significant difference in baseline 25(OH)D levels, but there was a significant increase in median 25(OH)D in the vitamin D3 group (57.5-105 nmol/l) compared with the PL group (52.5-57.5 nmol/l) (p < 0.0001). There was no significant difference between groups regarding subjective asthma control. Compared with PL, there was a significant decrease in school days missed due to asthma (1 vs. 5 days, p = 0.04) and alkaline phosphatase (-3.4 vs. +16; p = 0.037) in the vitamin D3 group, but there were no beneficial effects regarding several other secondary end-points. However, there were non-significant, advantageous changes in the PL group compared with the vitamin D3 group in subjective asthma control and lung function, particularly percentage of predicted forced expiratory volume in 1 s (+2.5 vs. -4; p = 0.06). Vitamin D3 supplementation led to a significant increase in serum 25(OH)D and decreased school days missed (p = 0.04), but no other advantageous changes in asthma parameters compared with PL. The potential adverse effect of vitamin D deficiency on growth and the potential negative effect of high serum 25(OH)D on pulmonary function warrant further investigation. © 2016 John Wiley & Sons A/S.

Phenylpropanolamine (PPA)-induced appetite control is associated with oxidative stress in the hypothalamus. This study explored whether hypothalamic antioxidants participated in hypothalamic ghrelin system-associated appetite control in PPA-treated rats. Rats were given PPA daily for 4 days, and changes in food intake and the expression of neuropeptide Y (NPY), the cocaine- and amphetamine-regulated transcript (CART), superoxide dismutase, catalase, ghrelin, acyl ghrelin (AG), ghrelin O-acyltransferase (GOAT) and the ghrelin receptor (GHSR1a) were examined and compared. Results showed that both food intake and the expression of NPY and ghrelin/AG/GOAT/GHSR1a decreased in response to PPA treatment with maximum decrease on Day 2 of the treatment. In contrast, the expression of antioxidants and CART increased, with the maximum increase on Day 2, with the expression opposite to that of NPY and ghrelin. A cerebral infusion of either a GHSR1a antagonist or reactive oxygen species scavenger modulated feeding behavior and NPY, CART, antioxidants and ghrelin system expression, showing the involvement of ghrelin signaling and oxidative stress in regulating PPA-mediated appetite control. We suggest that hypothalamic ghrelin signaling system, with the help of antioxidants, may participate in NPY/CART-mediated appetite control in PPA-treated rats. © 2016 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

Effect of piracetam and nimodipine on full-thickness skin burns in rabbits.

The potential of several drugs for full-thickness skin burns has been investigated, but the treatment of such burns remains a challenge in plastic surgery. The present study was designed to determine the effect of systemic and topical administration of piracetam and nimodipine on full-thickness skin burn wound healing. A total of 36 New Zealand male rabbits were divided into six groups. Full-thickness skin burns were produced in all the groups, except the control group. Piracetam was administered systemically (piracetam-IV) and topically (piracetam-C) for 14 days, and nimodipine was administered systemically (nimodipine-IV) and topically (nimodipine-C) over the burn wounds for 14 days. The sham group underwent burn injury but was not administered any drug. After 21 days, gross examination and histopathological analysis were performed and the results were compared statistically. Nimodipine-C and nimodipine-IV had no effect on burn wound healing. However, both piracetam-IV and piracetam-C significantly enhanced the healing of the full-thickness skin burn wounds, although the latter was more effective, useful and practical in burn wound healing. The histopathological features of the wounds in the piracetam-C group were closer to those of the control group than those of the other groups. Piracetam-C rather than piracetam-IV may promote full-thickness burn wound healing in rabbits. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Upstream migration of Pacific lampreys in the John Day River, Oregon: Behavior, timing, and habitat use

USGS Publications Warehouse

Robinson, T. Craig; Bayer, J.M.

2005-01-01

Adult Pacific lamprey migration and habitat preferences for over-winter holding and spawning, and larval rearing in tributaries to the Columbia River are not well understood. The John Day River is one such tributary where larval and adult stages of this species have been documented, and its free-flowing character provided the opportunity to study migration of Pacific lampreys unimpeded by passage constraints. Forty-two adult Pacific lampreys were captured in the John Day River near its mouth during their upstream migration. Pacific lampreys were surgically implanted with radio transmitters and released onsite, and tracked by fixed-site, aerial, and terrestrial telemetry methods for nearly one year. Adults moved upstream exclusively at night, with a mean rate of 11.1 ?? 6.3 km/day. They halted upstream migration by September, and held a single position for approximately six months in the lateral margins of riffles and glides, using boulders for cover. More than half of Pacific lampreys resumed migration in March before ending movement in early May. Pacific lampreys that resumed migration in spring completed a median of 87% of their upstream migration before over-winter holding. Upon completing migration. Pacific lampreys briefly held position before beginning downstream movement at the end of May. Though not directly observed, halting migration and movement downstream were likely the result of spawning and death. Gains in adult Pacific lamprey passage through the Columbia River hydrosystem and tributaries may be made by improvements that would expedite migration during spring and summer and increase the quantity and variety of cover and refuge opportunities. ?? 2005 by the Northwest Scientific Association.

Minimum Flows and Levels Method of the St. Johns River Water Management District, Florida, USA

NASA Astrophysics Data System (ADS)

Neubauer, Clifford P.; Hall, Greeneville B.; Lowe, Edgar F.; Robison, C. Price; Hupalo, Richard B.; Keenan, Lawrence W.

2008-12-01

The St. Johns River Water Management District (SJRWMD) has developed a minimum flows and levels (MFLs) method that has been applied to rivers, lakes, wetlands, and springs. The method is primarily focused on ecological protection to ensure systems meet or exceed minimum eco-hydrologic requirements. MFLs are not calculated from past hydrology. Information from elevation transects is typically used to determine MFLs. Multiple MFLs define a minimum hydrologic regime to ensure that high, intermediate, and low hydrologic conditions are protected. MFLs are often expressed as statistics of long-term hydrology incorporating magnitude (flow and/or level), duration (days), and return interval (years). Timing and rates of change, the two other critical hydrologic components, should be sufficiently natural. The method is an event-based, non-equilibrium approach. The method is used in a regulatory water management framework to ensure that surface and groundwater withdrawals do not cause significant harm to the water resources and ecology of the above referenced system types. MFLs are implemented with hydrologic water budget models that simulate long-term system hydrology. The method enables a priori hydrologic assessments that include the cumulative effects of water withdrawals. Additionally, the method can be used to evaluate management options for systems that may be over-allocated or for eco-hydrologic restoration projects. The method can be used outside of the SJRWMD. However, the goals, criteria, and indicators of protection used to establish MFLs are system-dependent. Development of regionally important criteria and indicators of protection may be required prior to use elsewhere.

Literature describing medical treatment of canine prostatic carcinoma (PC) is sparse. The aims of this study were to assess outcomes, including time to progression (TTP) and median survival time (MST), of canine PC treated with non-steroidal anti-inflammatory drugs (NSAIDs) and/or chemotherapy, and to identify prognostic factors. Records from 8 institutions were searched for dogs with cytologically or histologically confirmed PC without bladder involvement: 67 dogs were included. Presenting signs were urinary (25), gastrointestinal ([GI], 11) and systemic (3); 16 dogs had GI and urinary signs, 7 dogs had systemic signs with concurrent GI or urinary signs and in 5 dogs the tumour was an incidental finding. Out of 27 dogs, 9 (33%) had positive urine culture. Metastases were identified in 26 dogs to lymph nodes (19), lungs (10), bone (2) and liver (1). Treatment included NSAIDs and chemotherapy (32), NSAIDs alone (31) and chemotherapy alone (4). The overall MST was 82 days (range 9-752) and median TTP was 63 days (range 9-752). Dogs receiving NSAIDs combined with chemotherapy experienced a significantly longer MST (106 vs 51 days; P = .035) and TTP (76 vs 44 days; P = .02) compared to dogs receiving NSAIDs alone. Intact dogs and those with metastatic disease had significantly shorter MST (31 vs 90 days, P = .018 and 49 vs 109 days, P = .037, respectively); intact dogs also had significantly shorter TTP (25 vs 63 days, P = .0003). This study suggests that a combination of NSAIDs and chemotherapy may improve outcomes in canine PC.

Topical formulations such as oily extracts or ointments prepared with the flowering aerial parts of St. John's wort (Hypericum perforatum L., Hypericaceae) have been used in the management of a wide range dermatological problems including superficial wounds and burns, bruises, contusions and many others in the worldwide traditional medicines. This is the first case study reporting the beneficial effects of an oily extract of St. John's wort in the treatment of pressure sores in a intensive care unit (ICU) patient. The oily extract of St. John's wort was applied to a volunteer patient at ICU daily for forty successive days for wound care and treatment. Healing status was monitored macroscopically by measuring the wound size and stages at certain intervals as well as histopathological evaluation of the tissue sections taken at the initial and final dates of treatment. Evaluation of the results obtained from the macroscopical and histopathological experimentation have shown that oily extract of St. John's wort provided significant efficacy for the treatment of pressure sore wounds. St. John's wort oily extract may be suggested as a cost-effective option for the prevention or treatment of pressure sores in ICU patients. Copyright © 2016 Elsevier Ireland Ltd.

This study was initiated to determine the extent of predation by resident populations of native and introduced fish on juvenile salmonids in main stem Columbia River Reservoirs. The John Day Reservoir and tailrace was selected as the study area. First year objectives were: (1) determine whether native and introduced predators preyed on juvenile salmonids; (2) determine which species were major predators; and (3) locate areas where predation was most intense. Results indicated that juvenile salmonids were consumed by all four predatory fish species studied: northern squawfish (Ptychocheilus oregonensis), walleye (Stizostedion vitreum vitreum), smallmouth bass (Micropterus dolomieu), and channel catfish (Ictalurusmore » punctatus). However, degree of predation varied among predators as a function of spatial distribution, apparent abundance, size, and temporal feeding behavior. 15 figs., 16 tabs.« less

We estimated the loss of juvenile salmonids Oncorhynchus spp. to predation by northern squawfish Ptychocheilus oregonensis, walleyes Stizostedion vitreum, and smallmouth bass Micropterus dolomieu in John Day Reservoir during 1983–1986. Our estimates were based on measures of daily prey consumption, predator numbers, and numbers of juvenile salmonids entering the reservoir during the April–August period of migration. We estimated the mean annual loss was 2.7 million juvenile salmonids (95% confidence interval, 1.9–3.3 million). Northern squawfish were responsible for 78% of the total loss; walleyes accounted for 13% and smallmouth bass for 9%. Twenty-one percent of the loss occurred in a small area immediately below McNary Dam at the head of John Day Reservoir. We estimated that the three predator species consumed 14% (95% confidence interval, 9–19%) of all juvenile salmonids that entered the reservoir. Mortality changed by month and increased late in the migration season. Monthly mortality estimates ranged from 7% in June to 61% in August. Mortality from predation was highest for chinook salmon O. tshawytscha, which migrated in July and August. Despite uncertainties in the estimates, it is clear that predation by resident fish predators can easily account for previously unexplained mortality of out-migrating juvenile salmonids. Alteration of the Columbia River by dams and a decline in the number of salmonids could have increased the fraction of mortality caused by predation over what it was in the past.

Here, we described the clinical characteristics and outcomes of central nervous system (CNS) infections occurring after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in a single institution over the previous 6 years. Charts of 353 consecutive allogeneic transplant recipients were retrospectively reviewed for CNS infection. A total of 17 cases of CNS infection were identified at a median of 38 days (range, 10-1028 days) after allo-HSCT. Causative pathogens were human herpesvirus-6 (n=6), enterococcus (n=2), staphylococcus (n=2), streptococcus (n=2), varicella zoster virus (n=1), cytomegalovirus (n=1), John Cunningham virus (n=1), adenovirus (n=1), and Toxoplasma gondii (n=1). The cumulative incidence of CNS infection was 4.1% at 1 year and 5.5% at 5 years. Multivariate analysis revealed that high-risk disease status was a risk factor for developing CNS infection (p=.02), and that overall survival at 3 years after allo-HSCT was 33% in patients with CNS infection and 53% in those without CNS infection (p=.04).

The immune response modifier Canova® is a homeopathic remedy indicated for patients with depressed immune system, since this drug appears to increase adaptive immunity and induce an immune response against multiple and severe pathological conditions, including cancer. We evaluated the pattern of immune cellular response in non-human primates of the species Cebus apella exposed to N-methyl-N-nitrosourea (MNU) with and without Canova®. Twelve animals were divided into four groups, with three animals each: negative control and three experimental groups, MNU-alone (35 days); MNU (35 days)-plus-Canova® (3 days) and Canova®-alone (3 days). The animals received MNU orally and Canova® by three intravenous injections. Evaluation of the cellular immune response was performed by immunophenotyping of T-lymphocytes (CD4(+), CD8(+)), B-lymphocytes and natural killer cells. Analysis was also performed of the cell cycle. Our results suggest an increase of T-lymphocytes (CD4(+)CD3(+)) only in the Canova® group, while in the MNU-plus-Canova® group only B-lymphocytes increased.

2015-12-01

Percutaneous coronary interventions (PCI) on acute myocardial infarction (AMI) patients have increased substantially in the last 12-15 years because of its clinical effectiveness. The expansion of PCI treatment for AMI patients raises two questions: How did PCI utilization rates vary across European regions, and which healthcare system and regional characteristic variables correlated with the utilization rate? Were the differences in use of PCI associated with differences in outcome, operationalized as 30-day mortality? We obtained our results from a dataset based on the administrative information systems of the populations of seven European countries. PCI rates were highest in the Netherlands, followed by Sweden and Hungary. The probability of receiving PCI was highest in regions with their own PCI facilities and in healthcare systems with activity-based reimbursement systems. Thirty-day mortality rates differed considerably between the countries with the highest rates in Hungary, Scotland, and Finland. Mortality was lowest in Sweden and Norway. The associations between PCI and mortality were remarkable in all age groups and across most countries. Despite extensive risk adjustment, we interpret the associations both as effects of selection and treatments. We observed a lower effect of PCI in the higher age groups in Hungary.

2006-12-01

Lord John Wrottesley (1798-1867) was a man of considerable importance in the field of 19th century science, particularly during the first three decades of the Victorian era. He held a number of important offices during this time, including being President of the Royal Astronomical Society (1841 to 1843), of which he was a founder member in 1820; President of the Royal Society 1854 to 1857; and President of the British Association for the Advancement of Science for 1860. He was always to seek a good understanding between scientists and government, and also to promote the general public understanding of science. Although today the name of Lord John Wrottesley is largely forgotten, he created a legacy that remains with us to the present day.

The Nez Perce Tribe, in cooperation with the U.S. Fish and Wildlife Service and Washington Department of Fish and Wildlife, conducted monitoring and evaluation studies on Lyons Ferry Hatchery reared yearling fall Chinook salmon Oncorhynchus tshawytscha that were acclimated and released at three Fall Chinook Acclimation Project sites upstream of Lower Granite Dam along with yearlings released on-station from Lyons Ferry Hatchery in 2000. This was the fifth year of a long-term project to supplement natural spawning populations of Snake River stock fall Chinook salmon upstream of Lower Granite Dam. The 397,339 yearlings released from the Fall Chinook Acclimation Projectmore » facilities were short of the 450,000 fish quota. We use Passive Integrated Transponder (PIT) tag technology to monitor the primary performance measures of survival to mainstem dams and migration timing. We also monitor size, condition and tag/mark retention at release. We released 7,477 PIT tagged yearlings from Pittsburg Landing, 7,421 from Big Canyon and 2,488 from Captain John Rapids. The Washington Department of Fish and Wildlife released 980 PIT tagged yearlings from Lyons Ferry Hatchery. Fish health sampling indicated that, overall, bacterial kidney disease levels could be considered relatively low. Compared to prior years, Quantitative Health Assessment Indices were relatively low at Big Canyon and Captain John Rapids and about average at Pittsburg Landing and Lyons Ferry Hatchery. Mean fork lengths (95% confidence interval) of the PIT tagged groups ranged from 157.7 mm (157.3-158.1 mm) at Big Canyon to 172.9 mm (172.2-173.6 mm) at Captain John Rapids. Mean condition factors ranged from 1.06 at Captain John Rapids and Lyons Ferry Hatchery to 1.12 at Big Canyon. Estimated survival (95% confidence interval) of PIT tagged yearlings from release to Lower Granite Dam ranged from 87.0% (84.7-89.4%) for Pittsburg Landing to 95.2% (91.5-98.9%) for Captain John Rapids. Estimated survival from release to McNary Dam ranged from 65.8% (58.5-73.1%) for Lyons Ferry Hatchery to 84.0% (76.2-91.8%) for Captain John Rapids. Median migration rates to Lower Granite Dam, based on all observations of PIT tagged yearlings from the FCAP facilities, ranged from 10.1 river kilometers per day (rkm/d) for Captain John Rapids to 19.1 rkm/d for Pittsburg Landing. Median migration rates to McNary Dam ranged from 6.0 rkm/d for Lyons Ferry Hatchery to 17.3 rkm/d for Pittsburg Landing. Median travel times from the FCAP facilities were about 9-10 days to Lower Granite Dam and 22-25 days to McNary Dam. Median arrival dates at Lower Granite Dam, based on all observations of PIT tagged yearling groups from Pittsburg Landing, Big Canyon and Captain John Rapids, were all from April 21-22. Median arrival dates at McNary Dam for Pittsburg Landing, Big Canyon and Captain John Rapids groups were all from May 5-6. The median arrival date at McNary Dam was April 24 for Lyons Ferry Hatchery yearlings.« less

Transplant recipients are at risk of developing Legionnaires' disease (LD) because of impaired cellular immunity. Here, we describe a renal transplant recipient who developed LD at least 10 days after hospital admission and transplantation. The hospital water network was initially suspected, but further testing determined that the probable source was the patient's domestic water supply. Our report also suggests that the patient's immunosuppressed state may have switched potential colonization to pneumonia. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Mill and mental phenomena: critical contributions to a science of cognition.

PubMed

Bistricky, Steven L

2013-06-01

Attempts to define cognition preceded John Stuart Mill's life and continue to this day. John Stuart Mill envisioned a science of mental phenomena informed by associationism, empirical introspection, and neurophysiology, and he advanced specific ideas that still influence modern conceptions of cognition. The present article briefly reviews Mill's personal history and the times in which he lived, and it traces the evolution of ideas that have run through him to contemporary cognitive concepts. The article also highlights contemporary problems in defining cognition and supports specific criteria regarding what constitutes cognition.

Objective methods are lacking for continuous monitoring of illness activity in bipolar disorder. Smartphones offer unique opportunities for continuous monitoring and automatic collection of real-time data. The objectives of the paper were to test the hypotheses that (i) daily electronic self-monitored data and (ii) automatically generated objective data collected using smartphones correlate with clinical ratings of depressive and manic symptoms in patients with bipolar disorder. Software for smartphones (the MONARCA I system) that collects automatically generated objective data and self-monitored data on illness activity in patients with bipolar disorder was developed by the authors. A total of 61 patients aged 18-60 years and with a diagnosis of bipolar disorder according to ICD-10 used the MONARCA I system for six months. Depressive and manic symptoms were assessed monthly using the Hamilton Depression Rating Scale 17-item (HDRS-17) and the Young Mania Rating Scale (YMRS), respectively. Data are representative of over 400 clinical ratings. Analyses were computed using linear mixed-effect regression models allowing for both between individual variation and within individual variation over time. Analyses showed significant positive correlations between the duration of incoming and outgoing calls/day and scores on the HDRS-17, and significant positive correlations between the number and duration of incoming calls/day and scores on the YMRS; the number of and duration of outgoing calls/day and scores on the YMRS; and the number of outgoing text messages/day and scores on the YMRS. Analyses showed significant negative correlations between self-monitored data (i.e., mood and activity) and scores on the HDRS-17, and significant positive correlations between self-monitored data (i.e., mood and activity) and scores on the YMRS. Finally, the automatically generated objective data were able to discriminate between affective states. Automatically generated objective data and self-monitored data collected using smartphones correlate with clinically rated depressive and manic symptoms and differ between affective states in patients with bipolar disorder. Smartphone apps represent an easy and objective way to monitor illness activity with real-time data in bipolar disorder and may serve as an electronic biomarker of illness activity. © 2015 John Wiley & Sons A/S.

Estimating the opportunity costs of bed-days.

PubMed

Sandmann, Frank G; Robotham, Julie V; Deeny, Sarah R; Edmunds, W John; Jit, Mark

2018-03-01

Opportunity costs of bed-days are fundamental to understanding the value of healthcare systems. They greatly influence burden of disease estimations and economic evaluations involving stays in healthcare facilities. However, different estimation techniques employ assumptions that differ crucially in whether to consider the value of the second-best alternative use forgone, of any available alternative use, or the value of the actually chosen alternative. Informed by economic theory, this paper provides a taxonomic framework of methodologies for estimating the opportunity costs of resources. This taxonomy is then applied to bed-days by classifying existing approaches accordingly. We highlight differences in valuation between approaches and the perspective adopted, and we use our framework to appraise the assumptions and biases underlying the standard approaches that have been widely adopted mostly unquestioned in the past, such as the conventional use of reference costs and administrative accounting data. Drawing on these findings, we present a novel approach for estimating the opportunity costs of bed-days in terms of health forgone for the second-best patient, but expressed monetarily. This alternative approach effectively re-connects to the concept of choice and explicitly considers net benefits. It is broadly applicable across settings and for other resources besides bed-days. © 2017 The Authors Health Economics published by John Wiley & Sons Ltd.

We have reported the efficacy of the salvage chemotherapy P-IMVP16/CBDCA for patients with diffuse large B cell lymphoma (DLBCL) who had previously received CHOP before the availability of rituximab (R). Here, we confirmed the efficacy of R combined with P-IMVP16/CBDCA as a salvage chemotherapy for patients with DLBCL, who had previously received R-CHOP. We retrospectively analysed 59 patients with relapse or refractory DLBCL (38 male patients and 21 female patients) presenting between June 2004 and June 2013. The patients received R 375 mg/m 2 on day 1, methylprednisolone 1000 mg/body for 3 days (from day 3 to day 5), ifosfamide 1000 mg/m 2 for 5 days (from day 3 to day 7), methotrexate 30 mg/m 2 on day 5 and day 12, etoposide 80 mg/m 2 for 3 days (from day 3 to day 5), and carboplatin 300 mg/m 2 on day 3 every 21 days. Patients aged 70 years or older were given 75% of the standard dose. The overall response rate (complete response + partial response) was 64.4%. The 2-year overall survival rate was 55.3%. The 2-year progression free survival rate was 34.7%. The 2-year overall survival rate was 61.5% for the relapse patients, and 15.6% for the refractory patients (p < 0.0001). One patient died because of sepsis related to the treatment regimen. Non-hematological adverse effects were mild and tolerable. The R-P-IMVP-16/CBDCA regimen displayed a significant activity in relapsed DLBCL, with acceptable toxicity, and should be considered a candidate for salvage chemotherapy.

Real-time Interplanetary Shock Prediction System

NASA Astrophysics Data System (ADS)

Vandegriff, J. D.; Ho, G. C.; Plauger, J. M.

2002-05-01

We are creating a system to predict the arrival times and maximum intensities of energetic storm particle (ESP) events at the earth using particle fluxes measured by the EPAM instrument aboard NASA's ACE spacecraft. Real-time flux measurements, consisting of 5 minute averages made available 24 hours per day by the NOAA Space Environment Center, are fed into algorithms looking for characteristic changes in flux, velocity dispersion, and anisotropy. These quantities typically show changes up to 3 hours before shock passage, and thus we expect our system to deliver enhanced probabilities for shock arrival with approximately the same lead time. Forecasting information will be made publicly available through http://sd-www.jhuapl.edu/ACE/EPAM/, the Johns Hopkins University Applied Physics Lab web site for the ACE/EPAM instrument. Early results on the training of our algorithms and comparisons with past shock data will be presented.

Does the Timing of Food Stamp Distribution Matter? A Panel-Data Analysis of Monthly Purchasing Patterns of US Households.

PubMed

Castellari, Elena; Cotti, Chad; Gordanier, John; Ozturk, Orgul

2017-11-01

In this paper, we examine the relationship between the timing of food stamp receipt and purchasing patterns. We combine data on state distribution dates of food stamps with scanner data on a panel of households purchases tracked between 2004 and 2011. We find that purchases of a variety of goods are meaningfully higher on receipt days, consistent with previous work that suggests that recipients are very impatient. Additionally, and importantly, estimates indicate that when food stamp receipt days fall on weekends, total monthly purchases within the same households are affected. In particular, monthly purchases of beer are higher when food stamps are distributed on a weekend rather than in months where benefits are distributed on weekdays. For these households, total beer purchases are between 4 and 5% higher in those months. Among households ineligible for food stamps, no effect is identified. These results demonstrate that the 'day-of-the-week' of SNAP treatment may have important impacts on household purchase habits. Copyright © 2016 John Wiley & Sons, Ltd.

Skin testing has a limited role in the diagnosis of non-immediate beta-lactam hypersensitivity in children. The aim of this study was to report the results of oral provocation tests performed without skin tests in children with non-immediate mild cutaneous reactions without systemic symptoms caused by beta-lactam antibiotics. Oral provocation tests with suspected antibiotics were performed to patients with non-immediate mild cutaneous reactions without systemic symptoms caused by beta-lactam antibiotics. Skin tests were not performed before provocation tests. A total of five doses were administered with half-an-hour intervals in increasing doses. Provocation was continued for 5 days. A total of 119 patients with a median age of 4.3 (IQR: 2-7.5) years, of whom 58% were males, were included in the study. Amoxicillin-clavulanic acid was the most frequently responsible agent in 87 (73.1%) patients, and most common type of rash was maculopapular in 74 (62.2%) patients. Four patients (3.4%) had an urticarial reaction during the provocation test. We did not experience any severe reactions during oral provocation test without previous skin tests performed to children with non-immediate mild cutaneous reactions without systemic symptoms. Omitting skin tests before oral provocation test in this group of children can help decreasing the burden of allergy clinics and alleviating the discomfort of children. © 2015 John Wiley & Sons A/S.

Cell therapy for the treatment of renal failure in the acute setting has proved successful, with therapeutic impact, yet development of a sustainable, portable bioartificial kidney for treatment of chronic renal failure has yet to be realized. Challenges in maintaining an anticoagulated blood circuit, the typical platform for solute clearance and support of the biological components, have posed a major hurdle in advancement of this technology. This group has developed a Bioartificial Renal Epithelial Cell System (BRECS) capable of differentiated renal cell function while sustained by body fluids other than blood. To evaluate this device for potential use in end-stage renal disease, a large animal model was established that exploits peritoneal dialysis fluid for support of the biological device and delivery of cell therapy while providing uraemic control. Anephric sheep received a continuous flow peritoneal dialysis (CFPD) circuit that included a BRECS. Sheep were treated with BRECS containing 1 × 10 8 renal epithelial cells or acellular sham devices for up to 7 days. The BRECS cell viability and activity were maintained with extracorporeal peritoneal fluid circulation. A systemic immunological effect of BRECS therapy was observed as cell-treated sheep retained neutrophil oxidative activity better than sham-treated animals. This model demonstrates that use of the BRECS within a CFPD circuit embodies a feasible approach to a sustainable and effective wearable bioartificial kidney. Copyright © 2016 John Wiley & Sons, Ltd.

Individualbased measures for comorbidity are of increasing importance for planning and funding health care services. No measurement for individualbased healthcare costs exist in Sweden. The aim of this study was to validate the Johns Hopkins ACG Case-Mix System's predictive value of polypharmacy (regular use of 4 or more prescription medicines) used as a proxy for health care costs in an elderly population and to study if the prediction could be improved by adding variables from a population based study i.e. level of education, functional status indicators and health perception. The Johns Hopkins ACG Case-Mix System was applied to primary health care diagnoses of 1402 participants (60-96 years) in a cross-sectional community based study in Karlskrona, Sweden (the Swedish National study on Ageing and Care) during a period of two years before they took part in the study. The predictive value of the Johns Hopkins ACG Case-Mix System was modeled against the regular use of 4 or more prescription medicines, also using age, sex, level of education, instrumental activity of daily living- and measures of health perception as covariates. In an exploratory biplot analysis the Johns Hopkins ACG Case-Mix System, was shown to explain a large part of the variance for regular use of 4 or more prescription medicines. The sensitivity of the prediction was 31.9%, whereas the specificity was 88.5%, when the Johns Hopkins ACG Case-Mix System was adjusted for age. By adding covariates to the model the sensitivity was increased to 46.3%, with a specificity of 90.1%. This increased the number of correctly classified by 5.6% and the area under the curve by 11.1%. The Johns Hopkins ACG Case-Mix System is an important factor in measuring comorbidity, however it does not reflect an individual's capability to function despite a disease burden, which has importance for prediction of comorbidity. In this study we have shown that information on such factors, which can be obtained from short questionnaires increases the probability to correctly predict an individual's use of resources, such as medications.

Patellar tendinopathy (jumper's knee) has a high prevalence in jumping athletes. Excessive load on the patellar tendon through high volumes of training and competition is an important risk factor. Structural changes in the tendon are related to a higher risk of developing patellar tendinopathy. The critical tendon load that affects tendon structure is unknown. The aim of this study was to investigate patellar tendon structure on each day of a 5-day volleyball tournament in an adolescent population (16-18 years). The right patellar tendon of 41 players in the Australian Volleyball Schools Cup was scanned with ultrasound tissue characterization (UTC) on every day of the tournament (Monday to Friday). UTC can quantify structure of a tendon into four echo types based on the stability of the echo pattern. Generalized estimating equations (GEE) were used to test for change of echo type I and II over the tournament days. Participants played between eight and nine matches during the tournament. GEE analysis showed no significant change of echo type percentages of echo type I (Wald chi-square = 4.603, d.f. = 4, P = 0.331) and echo type II (Wald chi-square = 6.070, d.f. = 4, P = 0.194) over time. This study shows that patellar tendon structure of 16-18-year-old volleyball players is not affected during 5 days of cumulative loading during a volleyball tournament. © 2015 John Wiley & Sons A/S.

Targeted sampling efforts by the authors for the signal crayfish, Pacifastacus leniusculus, from its native range in the John Day River Basin, Oregon, U.S.A. yielded entocytherid ostracods with a male copulatory complex so clearly different from other entocytherines that a new genus, Aurumcythere gen. nov. is proposed to receive them. This newly proposed, apparently nonsclerotized, genus with hook and spur-like prominences of the posteroventral end of the peniferum is the first new genus of the subfamily Entocytherinae named since Hobbs & Peters described Aphelocythere (= Waltoncythere) in 1977. Aurumcythere gen. nov. represents only the second genus of entocytherid known from the Pacific Northwest. Lack of sclerotization in Aurumcythere gen. nov. provides new insight into poorly understood mating behaviors of entocytherid ostracods.

Can Households Cope with Health Shocks in Vietnam?

2016-07-01

This paper investigates the economic impact of health shocks on working-age adults in Vietnam during 2004-2008, using a fixed effects specification. Health shocks cover disability and morbidity and are measured by 'days unable to carry out regular activity', 'days in bed due to illness/injury', and 'hospitalization'. Overall, Vietnamese households are able to smooth total non-health expenditures in the short run in the face of a significant rise in out-of-pocket health expenditures. However, this is accomplished through vulnerability-enhancing mechanisms, especially in rural areas, including increased loans and asset sales and decreased education expenditures. Female-headed and rural households are found to be the least able to protect consumption. Results highlight the need to extend and deepen social protection and universal health coverage. © 2015 The Authors. Health Economics published by John Wiley & Sons Ltd. © 2015 The Authors.

Heterogeneity in Smokers' Responses to Tobacco Control Policies.

PubMed

Nesson, Erik

2017-02-01

This paper uses unconditional quantile regression to estimate whether smokers' responses to tobacco control policies change across the distribution of smoking levels. I measure smoking behavior with the number of cigarettes smoked per day and also with serum cotinine levels, a continuous biomarker of nicotine exposure, using individual-level repeated cross-section data from the National Health and Nutrition Examination Surveys. I find that the cigarette taxes lead to reductions in both the number of cigarettes smoked per day and in smokers' cotinine levels. These reductions are most pronounced in the middle quantiles of both distributions in terms of marginal effects, but most pronounced in the lower quantiles in terms of tax elasticities. I do not find that higher cigarette taxes lead to statistically significant changes in the amount of nicotine smokers ingest from each cigarette. Copyright © 2015 John Wiley & Sons, Ltd.

This video, Part 1 of 4, shows the activities of the STS-109 crew (Scott Altman, Commander; Duane Carey, Pilot; John Grunsfeld, Payload Commander; Nancy Currie, James Newman, Richard Linnehan, Michael Massimino, Mission Specialists) during flight days 1 through 3. The activities from other flight days can be seen on 'STS 109 Mission Highlights Resource Tape' Part 2 of 4 (internal ID 2002137664), 'STS 109 Mission Highlights Resource Tape' Part 3 of 4 (internal ID 2002139471), and 'STS-109 Mission Highlights Resource Tape' Part 4 of 4 (internal ID 2002137577). The main activity recorded during flight day 1 is the liftoff of Columbia. Attention is given to suit-up, boarding, and pre-flight procedures. The pre-launch crew meal has no sound. The crew members often wave to the camera before liftoff. The jettisoning of the solid rocket boosters is shown, and the External Tank is seen as it falls to Earth, moving over African dunes in the background. There are liftoff replays, including one from inside the cockpit. The opening of the payload bay doors is seen from the rear of the shuttle's cockpit. The footage from flight day 2 shows the Flight Support System for bearthing the HST (Hubble Space Telescope). Crew preparations for the bearthing are shown. Flight day 3 shows the tracking of and approach to the HST by Columbia, including orbital maneuvers, the capture of the HST, and its lowering onto the Flight Support System. Many views of the HST are shown, including one which reveals an ocean and cloud background as the HST retracts a solar array.

While the interest in medicinal plants continues to grow, there is a lack of basic information with respect to efficient protocols for plant production. Recently, in vitro regeneration protocols have been developed to provide masses of sterile, consistent St. John's wort. The current study assessed the potential for acclimatization of in vitro grown St. John's wort plantlets to a nutrient film technique (NFT) hydroponic system in a controlled environment greenhouse. Quantitative analyses of hypericin, hyperforin and pseudohypericin in flower tissues were used as the parameters to assess the quality of the greenhouse-grown plants. The three bioactive compounds were found to be present in similar or higher amounts than previously reported values for field-grown plants. These data provide evidence that greenhouse hydroponic systems can be effectively used for the efficient production of St. John's wort and other medicinal plants.

Controversy exists regarding glucocorticoids therapy and the risk of peptic ulcer bleeding (PUB). The present study was undertaken to determine whether short-term use of glucocorticoids is associated with the occurrence of peptic ulcer bleeding. The records of adult patients hospitalised for newly diagnosed peptic ulcer bleeding from 2000 to 2012 were retrieved from the Taiwan National Health Insurance Research Database, a nationwide population-based registry system. The association between systemic glucocorticoids usage and peptic ulcer bleeding was determined with a conditional logistic regression model comparing cases and controls during time windows of 7, 14 and 28 days using a case-crossover design. Of the 8894 enrolled patients, the adjusted self-matched odds ratios for peptic ulcer bleeding after exposure to the glucocorticoids were 1.37 (95% CI: 1.12-1.68, P = 0.003) for the 7-day window, 1.66 (95% CI: 1.38-2.00, P < 0.001) for the 14-day window and 1.84 (95% CI: 1.57-2.16, P < 0.001) for the 28-day window. Moderate to high, but not low dose glucocorticoids (methylprednisolone <4 mg/day or its equivalence) were associated with an increased risk of peptic ulcer bleeding. Concomitant use of a nonselective nonsteroidal anti-inflammatory drug (NSAID) or aspirin further elevated the risk. However, it does not eliminate the effect of underlying diseases flare-up that may have placed the patients at risk for peptic ulcer bleeding in this kind of study design. Short-term (7-28 days) exposure to glucocorticoids is significantly associated with peptic ulcer bleeding; this risk seems dose-dependent and is higher when nonselective NSAIDs or aspirin are used concurrently. © 2015 John Wiley & Sons Ltd.

To review the current literature on hospital nursing factors associated with 30-day readmission rates of patients with heart failure. Heart failure is a common, yet debilitating chronic illness with high mortality and morbidity. One in five patients with heart failure will experience unplanned readmission to a hospital within 30 days. Given the significance of heart failure to individuals, families and healthcare system, the Center for Medicare and Medicaid Services has made reducing 30-day readmission rates a priority. Scoping review, which maps the key concepts of a research area, is used. Published primary studies in English assessing factors related to nurses in hospitals and readmission of patients with heart failure were included. Other inclusion criteria were written in English and published in peer-reviewed journals. The search resulted in 2,782 articles. After removing duplicates and reviewing the inclusion and exclusion criteria, five articles were selected. Three nursing workforce factors emerged as follows: (i) nursing staffing, (ii) nursing care and work environment, and (iii) nurses' knowledge of heart failure. This is the first scoping review examining the association between hospital nursing factors and 30-day readmission rates of patients with heart failure. Further studies examining the extent of nursing structural and process factors influencing the outcomes of patients with heart failure are needed. Nurses are an integral part of the healthcare system. Identifying the factors related to nurses in hospitals is important to ensure comprehensive delivery of care to the chronically ill population. Hospital administrators, managers and policymakers can use the findings from this review to implement strategies to reduce 30-day readmission rates of patients with heart failure. © 2018 John Wiley & Sons Ltd.

The sensitivity of the adaptive model of the Athlete Biological Passport (ABP) and reticulocyte percentage (ret%) in detection of recombinant human erythropoietin (rHuEPO) misuse was evaluated using both a long-term normal dose and a brief high dose treatment regime. Sixteen subjects received either 65 IU rHuEPO × kg -1 every second day for two weeks (normal-dose), 390 IU rHuEPO × kg -1 on three consecutive days (high-dose), or frequent placebo treatment for 13 days in a randomized, placebo-controlled, double-blind crossover design. Blood variables were measured 4, 11, and 25 days following treatment initiation. The ABP based on haemoglobin concentration ([Hb]) and OFF-hr score ([Hb] - 60 × √ret%) yielded atypical profiles following both normal-dose and high-dose treatment (0 %, 31 %, 13 % vs. 21 %, 33 %, 20 % at days 4, 11, and 25 after normal and high dose, respectively). Including ret% as a stand-alone marker for atypical blood profiles increased (P < 0.05) the sensitivity of the adaptive model at day 11 to 63 % and 67 % for normal-dose and high-dose rHuEPO administration, respectively. In conclusion, ~30 % of subjects injecting a normal-dose rHuEPO for two weeks or a high-dose rHuEPO for three days will present an atypical ABP profile. Including ret% as a stand-alone parameter improves the sensitivity two-fold. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

Estimated discharge and chemical-constituent loading from the upper Floridan aquifer to the lower St John's River, northeastern Florida, 1990-91

USGS Publications Warehouse

Spechler, R.M.

1995-01-01

The lower St. Johns River, a 101-mile long segment of the St. Johns River, begins at the confluence of the Ocklawaha River and ends where the river discharges into the Atlantic Ocean at Mayport. The St. Johns River is affected by tides as far upstream as Lake George, 106 miles from the mouth. Saltwater from the ocean advances inland during each incoming tide and recedes during each outgoing tide. The chemical quality of the lower St. Johns River is highly variable primarily because of the inflow of saltwater from the ocean, and in some areas, from the discharge of mineralized ground water. Three hydrogeologic units are present in the study area: the surficial aquifer system, the intermediate confining unit, and the Floridan aquifer system. The surficial aquifer system overlies the intermediate confining unit and consists of deposits containing sand, clay, shell, and some limestone and dolomite. The intermediate confining unit underlies all of the study area and retards the vertical movement of water between the surficial aquifer system and the Floridan aquifer system. The intermediate confining unit consists of beds of relatively low permeability sediments that vary in thickness and areal extent and can be breached by sinkholes, fractures, and other openings. The Floridan aquifer system primarily consists of limestone and dolomite. The quality of water in the Upper Floridan aquifer varies throughout the study area. Dissolved solids in water range from about 100 to more than 5,000 milligrams per liter. Chloride and sulfate concentrations in water from the Upper Floridan aquifer range from about 4 to 3,700 milligrams per liter and from 1 to 1,300 milligrams per liter, respectively. The rate of leakage through the intermediate confining unit is controlled by the leakance coefficient of the intermediate confining unit and by the head difference between the Upper Floridan aquifer and the surficial aquifer system. The total ground-water discharge from the Upper Floridan aquifer to the St. Johns River within the lower St. Johns River drainage basin, based on the potentiometric surface of the Upper Floridan aquifer in September 1990, was estimated to be 86 cubic feet per second. Total estimated ground-water discharge to the lower St. Johns River in September 1991, when heads in the Upper Floridan aquifer averaged about 4 feet higher than in 1990, was 133 cubic feet per second. The load of dissolved-solids that discharged from the Upper Floridan aquifer into the lower St. Johns River on the basis of September 1990 heads is estimated to be 47,000 tons per year. Estimated chloride and sulfate loads are 18,000 and 9,500 tons per year, respectively. Dissolved-solids, chloride, and sulfate loads discharging into the lower St. Johns River are estimated to be 81,000, 39,000, and 15,000 tons per year, respectively, on the basis of September 1991 heads.

From salmon to shad: Shifting sources of marine-derived nutrients in the Columbia River Basin

USGS Publications Warehouse

Haskell, Craig A.

2018-01-01

Like Pacific salmon (Oncorhynchus spp.), nonnative American shad (Alosa sapidissima) have the potential to convey large quantities of nutrients between the Pacific Ocean and freshwater spawning areas in the Columbia River Basin (CRB). American shad are now the most numerous anadromous fish in the CRB, yet the magnitude of the resulting nutrient flux owing to the shift from salmon to shad is unknown. Nutrient flux models revealed that American shad conveyed over 15,000 kg of nitrogen (N) and 3,000 kg of phosphorus (P) annually to John Day Reservoir, the largest mainstem reservoir in the lower Columbia River. Shad were net importers of N, with juveniles and postspawners exporting just 31% of the N imported by adults. Shad were usually net importers of P, with juveniles and postspawners exporting 46% of the P imported by adults on average. American shad contributed <0.2% of the total annual P load into John Day Reservoir, but during June when most adult shad are migrating into John Day Reservoir, they contributed as much as 2.0% of the P load. Nutrient inputs by American shad were similar to current but far less than historical inputs of Pacific salmon owing to their smaller size. Given the relatively high background P levels and low retention times in lower Columbia River reservoirs, it is unlikely that shad marine-derived nutrients affect nutrient balances or food web productivity through autotrophic pathways. However, a better understanding of shad spawning aggregations in the CRB is needed.

Pediatric patients undergoing small bowel transplantation are susceptible to postoperative CLABSI. SDD directed against enteric microbes is a strategy for reducing CLABSI. We hypothesized that SDD reduces the frequency of CLABSI, infections outside the bloodstream, and allograft rejection during the first 30 days following transplant. A retrospective chart review of 38 pediatric small bowel transplant recipients at CCHMC from 2003 to 2011 was conducted. SDD antimicrobials were oral colistin, tobramycin, and amphotericin B. The incidence of CLABSI, infections outside the bloodstream, and rejection episodes were compared between study periods. The incidence of CLABSI did not differ between study periods (6.9 CLABSI vs. 4.6 CLABSI per 1000 catheter days; p = 0.727), but gram positives and Candida predominated in the first 30 days. Incidence of bacterial infections outside the bloodstream did not differ (p = 0.227). Rejection occurred more frequently during the first month following transplant (p = 0.302). SDD does not alter the incidence of CLABSI, bacterial infections outside the bloodstream, or allograft rejection in the immediate 30 days post-transplantation. However, SDD does influence CLABSI organism types (favoring gram positives and Candida) and Candidal infections outside the bloodstream. © 2015 John Wiley & Sons A/S.

Sport injury epidemiology has received increased recognition as a field of sport medicine research that can improve the health and safety of athletes. Injuries among Paralympic powerlifters have not previously been systematically studied. The purpose of this prospective cohort study was to characterize injuries among Paralympic powerlifters. Athletes competing in the sport of powerlifting were followed over the 7-day competition period of the 2012 London Paralympic Games. The main outcome measurements were injury incidence rate (IR; number of injuries per 1000 athlete-days) and injury incidence proportion (IP; injuries per 100 athletes). A total of 38 injuries among 163 powerlifters were documented. The overall IR was 33.3 injuries/1000 athlete-days (95% CI 24.0-42.6) and the overall IP was 23.3 injuries per 100 athletes (95% CI 16.8-29.8). The majority of injuries were chronic overuse injuries (61%). The most commonly injured anatomical region was the shoulder/clavicle (32% of all injuries), followed by the chest (13%) and elbow (13%). The information obtained in this study opens the door for future study into the mechanisms and details of injuries into powerlifters with physical impairments. © 2015 John Wiley & Sons A/S.

Elliott, J.; Melkonian, A. K.; Pritchard, M. E.

2012-12-01

Glaciers in southeast Alaska are undergoing rapid changes and are significant contributors to sea level rise. A key to understanding the ice dynamics is knowledge of the surface velocities, which can be used with ice thickness measurements to derive mass flux rates. For many glaciers in Alaska, surface velocity estimates either do not exist or are based on data that are at least a decade old. Here we present updated maps of glacier surface velocities in southeast Alaska produced through a pixel tracking technique using synthetic aperture radar data and high-resolution optical imagery. For glaciers with previous velocity estimates, we will compare the results and discuss possible implications for ice dynamics. We focus on Glacier Bay and the Stikine Icefield, which contain a number of fast-flowing tidewater glaciers including LeConte, Johns Hopkins, and La Perouse. For the Johns Hopkins, we will also examine the influence a massive landslide in June 2012 had on flow dynamics. Our velocity maps show that within Glacier Bay, the highest surface velocities occur on the tidewater glaciers. La Perouse, the only Glacier Bay glacier to calve directly into the Pacific Ocean, has maximum velocities of 3.5 - 4 m/day. Johns Hopkins Glacier shows 4 m/day velocities at both its terminus and in its upper reaches, with lower velocities of ~1-3 m/day in between those two regions. Further north, the Margerie Glacier has a maximum velocity of ~ 4.5 m/day in its upper reaches and a velocity of ~ 2 m/day at its terminus. Along the Grand Pacific terminus, the western terminus fed by the Ferris Glacier displays velocities of about 1 m/day while the eastern terminus has lower velocities of < 0.5 m/day. The lake terminating glaciers along the Pacific coast have overall lower surface velocities, but they display complex flow patterns. The Alsek Glacier displays maximum velocities of 2.5 m/day above where it divides into two branches. Velocities at the terminus of the northern branch reach 1 m/day while the terminus of the southern branch moves about 2 m/day. Grand Plateau Glacier also divides into two main branches, with a northern branch displaying peak velocities of 1.5 m/day and a southern branch flowing at a rate of 1 m/day. The Stikine Icefield contains a number of large tidewater glaciers showing maximum velocities near their termini. At the terminus of the South Sawyer Glacier, velocities reach a peak of about 2 m/day. Along the terminus of the Dawes Glacier, velocities reach 3.5 m/day. The Baird Glacier displays lower velocities of 1-1.5 m/day. LeConte Glacier has 2-3 m/day velocities in its upper regions with higher velocities near its terminus. In contrast to the pattern shown by the surrounding glaciers, the Great Glacier has a peak velocity of 2 m/day in the upper portion of the glacier and a velocity of only 0.5 m/day near its terminus.

To determine the outcome of clinically negative node (cN0) patients with penile cancer undergoing dynamic sentinel node biopsy (DSNB), comparing the results of a 1- and 2-day protocol that can be used as a minimal invasive procedure for staging of penile cancer. This is a retrospective analysis of 151 cN0 patients who underwent DSNB from 2008 to 2013 for newly diagnosed penile cancer. Data were analysed per groin and separated into groups according to the protocol followed. The comparison of the two protocols involved the number of nodes excised, γ-counts, false-negative rates (FNR), and complication rates (Clavien-Dindo grading system). In all, 280 groins from 151 patients underwent DSNB after a negative ultrasound ± fine-needle aspiration cytology. The 1-day protocol was performed in 65 groins and the 2-day protocol in 215. Statistically significantly more nodes were harvested with the 1-day protocol (1.92/groin) compared with the 2-day protocol (1.60/groin). The FNRs were 0%, 6.8% and 5.1%, for the 1-day protocol, 2-day protocol, and overall, respectively. Morbidity of the DSNB was 21.4% for all groins, and 26.2% and 20.1% for the 1-day and 2-day protocols, respectively. Most of the complications were of Clavien-Dindo Grade 1-2. DSNB is safe for staging patients with penile cancer. There is a trend towards a 1-day protocol having a lower FNR than a 2-day protocol, albeit at the expense of a slightly higher complication rate. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

Exploration of the Theoretical Physical Capacity of the John F. Kennedy International Airport Runway System

Neitzke, Kurt W.; Guerreiro, Nelson M.

2014-01-01

A design study was completed to explore the theoretical physical capacity (TPC) of the John F. Kennedy International Airport (KJFK) runway system for a northflow configuration assuming impedance-free (to throughput) air traffic control functionality. Individual runways were modeled using an agent-based, airspace simulation tool, the Airspace Concept Evaluation System (ACES), with all runways conducting both departures and arrivals on a first-come first-served (FCFS) scheduling basis. A realistic future flight schedule was expanded to 3.5 times the traffic level of a selected baseline day, September 26, 2006, to provide a steady overdemand state for KJFK runways. Rules constraining departure and arrival operations were defined to reflect physical limits beyond which safe operations could no longer be assumed. Safety buffers to account for all sources of operational variability were not included in the TPC estimate. Visual approaches were assumed for all arrivals to minimize inter-arrival spacing. Parallel runway operations were assumed to be independent based on lateral spacing distances. Resulting time intervals between successive airport operations were primarily constrained by same-runway and then by intersecting-runway spacing requirements. The resulting physical runway capacity approximates a theoretical limit that cannot be exceeded without modifying runway interaction assumptions. Comparison with current KJFK operational limits for a north-flow runway configuration indicates a substantial throughput gap of approximately 48%. This gap may be further analyzed to determine which part may be feasibly bridged through the deployment of advanced systems and procedures, and which part cannot, because it is either impossible or not cost-effective to control. Advanced systems for bridging the throughput gap may be conceptualized and simulated using this same experimental setup to estimate the level of gap closure achieved.

Dental avulsion damages periodontal tissues and may induce dentoalveolar ankylosis and root resorption after replantation. The aim of this work was to evaluate the effects of light-emitting diode (LED) therapy after tooth replantation. The upper right incisors of 36 male Wistar rats were extracted and replanted after 15 min. The control group (Co, n = 18) was submitted to replantation and the LED group (n = 18) was submitted to replantation and LED therapy (940 nm, 4 J cm -2 ) for three consecutive days (0, 24, and 48 h). Six animals from each group were euthanized at 7, 14, and 21 days for histological analysis. The upper left incisors were used as a negative control. Data were compared using the Fisher exact test, considering P < 0.05. After 7 days, the Co (73.3%) and LED (72.2%) groups presented areas of periodontal ligament necrosis. However, periodontal ligament necrosis was more frequent in the LED group at 14 (70%, P < 0.05) and 21 days (43.2%, P < 0.05) in relation to the Co group (33 and 21.6%). Inflammatory cell infiltration was more frequent in the Co group at 7 days (100%) than the LED group (24.4%, P < 0.05), but increased in the LED group after 21 days (83.3%, P < 0.05). Bone necrosis was more frequent in the LED group after 14 (79%, P < 0.05) and 21 days (60%, P < 0.005) than in the Co group (45% and 20%). Bone repair was evident in the Co group at 14 days. All of the replanted teeth had pulp necrosis. The results suggest that the application of LED therapy up to 48 h after tooth replantation may delay periodontal ligament repair. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Juvenile Radio-Tag Study: Lower Granite Dam, 1985 Annual Report.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Stuehrenberg, Lowell C.

The concept of using mass releases of juvenile radio tags represents a new and potentially powerful research tool that could be effectively applied to juvenile salmonid passage problems at dams on the Columbia and Snake Rivers. A system of detector antennas, strategically located, would automatically detect and record individually tagged juvenile salmonids as they pass through the spillway, powerhouse, bypass system, or tailrace areas below the dam. Accurate measurements of spill effectiveness, fish guiding efficiency (FGE), collection efficiency (CE), spillway survival, powerhouse survival, and bypass survival would be possible without handling large numbers of unmarked fish. A prototype juvenile radio-tagmore » system was developed and tested by the National Marine Fisheries Service (NMFS) and Bonneville Power Administration (BPA) at John Day Dam and at Lower Granite Dam. This report summarizes research to: (1) evaluate the effectiveness of the prototype juvenile radio-tag system in a field situation and (2) to test the basic assumptions inherent in using the juvenile radio tag as a research tool.« less

2013-01-01

Attempts to define cognition preceded John Stuart Mill’s life and continue to this day. John Stuart Mill envisioned a science of mental phenomena informed by associationism, empirical introspection, and neurophysiology, and he advanced specific ideas that still influence modern conceptions of cognition. The present article briefly reviews Mill’s personal history and the times in which he lived, and it traces the evolution of ideas that have run through him to contemporary cognitive concepts. The article also highlights contemporary problems in defining cognition and supports specific criteria regarding what constitutes cognition. PMID:25379235

Myrosinase (thioglucoside glucohydrolase; E.C. 3.2.1.147), is a plant enzyme of increasing interest and importance to the biomedical community. Myrosinase catalyses the formation of isothiocyanates such as sulforaphane (from broccoli) and 4-(α-l-rhamnopyranosyloxy)benzyl isothiocyanate (from moringa), which are potent inducers of the cytoprotective phase-2 response in humans, by hydrolysis of their abundant glucosinolate (β-thioglucoside N-hydroxysulphate) precursors. To develop an aqueous two-phase counter-current chromatography (CCC) system for the rapid, three-step purification of catalytically active myrosinase. A high-concentration potassium phosphate and polyethylene glycol biphasic aqueous two-phase system (ATPS) is used with a newly developed CCC configuration that utilises spiral-wound, flat-twisted tubing (with an ovoid cross-section). Making the initial crude plant extract directly in the ATPS and injecting only the lower phase permitted highly selective partitioning of the myrosinase complex before a short chromatography on a spiral disk CCC. Optimum phase retention and separation of myrosinase from other plant proteins afforded a 60-fold purification. Catalytically active myrosinase is purified from 3-day broccoli sprouts, 7-day daikon sprouts, mustard seeds and the leaves of field-grown moringa trees, in a CCC system that is predictably scalable.

The synergistic activity of Houttuynia cordata ethanol extract (HCT) and metformin combination in diabetic rats has been previously reported, but the fundamental causes remain unsolved. Organic cation transporters (OCTs) and multidrug and toxin extrusion proteins (MATEs) transport metformin to the liver and kidneys. Therefore, pharmacological activity and systemic exposure of metformin in HCT-metformin combination were determined from pharmacokinetic change and glucose-lowering activity using in vitro HEK-293 cells expressing human OCTs or human MATEs and in vivo rats. HCT inhibited human OCT2 and human MATE1-mediated metformin transports in vitro. In in vivo rats, treatment with HCT and metformin for 28 days in rats (28MH rats) reduced the rat Oct2-mediated renal excretion of metformin and thereby the increased systemic exposure of metformin compared with only metformin-treated rats for 28 days (28M rats). In 28MH rats, rat Oct1-mediated metformin uptake into the liver was enhanced, leading to an improved glucose-lowering effect without hypoglycaemia compared with 28M rats. There was no impairment of renal function in HCT and metformin treatments. These results suggest that HCT-metformin combination therapy is applicable in terms of efficacy and safety.

To assess in a periodontally diseased rural population deprived from regular dental care and having poor dietary conditions, the effect of vitamin C/calcium threonate/citrus flavonoids (VitC/Ca/Fl) supplementation on subgingival microbiota and plasma levels of vitamin C, HbA1c and hsCRP. The study population consisted of 98 subjects who previously participated in a prospective study on the natural history of periodontitis. Participants were instructed to consume one tablet/day containing 200 mg Ester C(®) calcium ascorbate, 25 mg calcium threonate and 100 mg citrus flavonoids for 90 days. Following parameters were evaluated: prevalence/amount of seven traditional periodontal pathogens, cytomegalovirus, Epstein-Barr virus (EBV); and plasma levels of vitamin C, HbA1c and hsCRP. After VitC/Ca/Fl supplementation, 100% of subjects showed normal plasma vitamin C values compared to 55% before. At baseline, 48% of subjects harboured Aggregatibacter actinomycetemcomitans, >97% the other periodontal pathogens and 73% EBV. Supplementation with VitC/Ca/F reduced the subgingival load of all studied bacteria (p-values: 0.014-0.0001) and EBV (p < 0.0001) substantially in all initially positive subjects. Plasma levels of HbA1c and hsCRP dropped in all subjects (p < 0.0001). This uncontrolled study suggested that supplemental VitC/Ca/Fl may be helpful in reducing subgingival numbers of periodontal pathogens and EBV, and promoting systemic health. © 2015 John Wiley & Sons A/S.

To investigate the efficacy of two formulations of chlorhexidine 0.2% (CHX) mouthrinses in terms of oral hygiene and gingival health status in adolescents with fixed orthodontic appliances wearing two different types of brackets during 18 weeks. Eighty subjects were randomly divided into two equal groups according to brackets type: (i) metal-stainless steel, (ii) ceramic. Four weeks after the placement of the fixed orthodontic appliances the subjects from each group were randomly allocated into two equal subgroups and were provided with two different mouthrinses for 14 days: (i) alcohol-free CHX, (ii) CHX with antidiscoloration system (CHX-ADS). Assessment was carried out according to gingival index (GI) and oral hygiene index-simplified (OHI-S) performed prior to the placement of the appliance (t 1 ), 6 weeks (t 2 ), and 18 weeks (t 3 ) after the placement. To analyse the data, two-way mixed model MANOVA. Pearson correlations, one-way ANOVA and Independent Samples t test were conducted. Statistically significant decrease in GI and OHI-S indices after 6 weeks and then increase after 18 weeks for all groups was found. Both GI and OHI-S values were lower in subjects wearing ceramic brackets, with statistically significant difference for GI after the usage of the mouthrinse for 14 days, at t 2 (P<.05). The results revealed that the ceramic brackets as well as usage of CHX-ADS resulted in improved gingival status. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The goal of the present study was to investigate the effects of lithium administration on behavior, oxidative stress parameters and cytokine levels in the periphery and brain of mice subjected to an animal model of mania induced by paradoxical sleep deprivation (PSD). Male C57 mice were treated with saline or lithium for 7 days. The sleep deprivation protocol started on the 5th day during for the last 36 hours of the treatment period. Immediately after the sleep deprivation protocol, animals locomotor activity was evaluated and serum and brain samples was extracted to evaluation of corticosterone and adrenocorticotropic hormone circulating levels, oxidative stress parameters and citokynes levels. The results showed that PSD induced hyperactivity in mice, which is considered a mania-like behavior. PSD increased lipid peroxidation and oxidative damage to DNA, as well as causing alterations to antioxidant enzymes in the frontal cortex, hippocampus and serum of mice. In addition, PSD increased the levels of cytokines in the brains of mice. Treatment with lithium prevented the mania-like behavior, oxidative damage and cytokine alterations induced by PSD. Improving our understanding of oxidative damage in biomolecules, antioxidant mechanisms and the inflammatory system - alterations presented in the animal models of mania - is important in helping us to improve our knowledge concerning the pathophysiology of BD, and the mechanisms of action employed by mood stabilizers. © 2017 John Wiley & Sons A/S.

The Nez Perce Tribe, in cooperation with the U.S. Fish and Wildlife Service and Washington Department of Fish and Wildlife, conducted monitoring and evaluation studies on Lyons Ferry Hatchery reared yearling fall Chinook salmon Oncorhynchus tshawytscha that were acclimated and released at three Fall Chinook Acclimation Project (FCAP) sites upstream of Lower Granite Dam along with yearlings released on-station from Lyons Ferry Hatchery in 1999. This was the fourth year of a long-term project to supplement natural spawning populations of Snake River stock fall Chinook salmon upstream of Lower Granite Dam. The 453,117 yearlings released from the Fall Chinook Acclimationmore » Project facilities not only slightly exceeded the 450,000 fish quota, but a second release of 76,386 yearlings (hereafter called Surplus) were acclimated at the Big Canyon facility and released about two weeks after the primary releases. We use Passive Integrated Transponder (PIT) tag technology to monitor the primary performance measures of survival to mainstem dams and migration timing. We also monitor size, condition and tag/mark retention at release. We released 9,941 PIT tagged yearlings from Pittsburg Landing, 9,583 from Big Canyon, 2,511 Big Canyon Surplus and 2,494 from Captain John Rapids. The Washington Department of Fish and Wildlife released 983 PIT tagged yearlings from Lyons Ferry Hatchery. Fish health sampling indicated that, overall, bacterial kidney disease levels could be considered relatively low and did not appear to increase after transport to the acclimation facilities. Compared to prior years, Quantitative Health Assessment Indices were relatively low at Pittsburg Landing and Lyons Ferry Hatchery and relatively high at Big Canyon and Captain John Rapids. Mean fork lengths (95% confidence interval) of the release groups ranged from 147.4 mm (146.7-148.1 mm) at Captain John Rapids to 163.7 mm (163.3-164.1 mm) at Pittsburg Landing. Mean condition factors ranged from 1.04 at Pittsburg Landing to 1.23 at Captain John Rapids. Estimated survival (95% confidence interval) of PIT tagged yearlings from release to Lower Granite Dam ranged from 87.8% (82.1-93.4%) for Big Canyon Surplus to 94.1% (90.1-98.1%) for Captain John Rapids. Estimated survival from release to McNary Dam ranged from 58.7% (49.3-68.1%) for Big Canyon Surplus to 71.3% (60.1-82.5%) for Captain John Rapids. Median migration rates to Lower Granite Dam, based on all observations of PIT tagged yearlings from the FCAP facilities, ranged from 9.3 river kilometers per day (rkm/d) for Captain John Rapids to 18.7 rkm/d for Pittsburg Landing. Median migration rates to McNary Dam ranged from 9.0 rkm/d for Lyons Ferry Hatchery to 17.3 rkm/d for Pittsburg Landing. Median travel times from the FCAP facilities were about 7-10 days to Lower Granite Dam and 21-23 days to McNary Dam. Median arrival dates at Lower Granite Dam, based on all observations of PIT tagged yearling groups from the FCAP facilities, were all from April 23-25. The median arrival date for Big Canyon Surplus was May 4. Median arrival dates at McNary Dam for Pittsburg Landing, Big Canyon and Captain John Rapids groups were all from May 7-8.

Indoor air quality was characterized in 10 recently built energy-efficient French schools during two periods of 4.5 days. Carbon dioxide time-resolved measurements during occupancy clearly highlight the key role of the ventilation rate (scheduled or occupancy indexed), especially in this type of building, which was tightly sealed and equipped with a dual-flow ventilation system to provide air refreshment. Volatile organic compounds (VOCs) and inorganic gases (ozone and NO2 ) were measured indoors and outdoors by passive techniques during the occupied and the unoccupied periods. Over 150 VOC species were identified. Among them, 27 species were selected for quantification, based on their occurrence. High concentrations were found for acetone, 2-butanone, formaldehyde, toluene, and hexaldehyde.

The ingestion of large amounts of boric acid, a component of household insecticides, is a rare occurrence, characterized by a diffuse desquamative skin eruption, neutropenia, thrombocytopenia, delirium, acute renal failure and prolonged ileus. A 56-year-old male with a history of multiple previous suicide attempts was witnessed ingesting household roach killer and 4 days later presented to the hospital with lethargy, stiffness and a diffuse erythematous and desquamative eruption with bullous formation. He subsequently developed erythema of both palms as well as alopecia totalis. Histopathology from a right arm shave biopsy revealed a mostly intact epidermis with subtle vacuolar alteration of the basal layer, scattered intraepidermal apoptotic keratinocytes, parakeratosis with alternating layers of orthokeratosis and considerable superficial exfoliation; accompanying dermal changes included vasodilatation and mild perivascular inflammation. This report describes the cutaneous and systemic complications in a rare case of boric acid ingestion. There is little published material on the symptoms and histopathology following boric acid ingestion, but knowledge of this entity is important, both to differentiate it from other causes of desquamative skin rashes and to allow the initiation of appropriate clinical care. © 2013 John Wiley & Sons A/S.

Fruits and vegetables are essential for healthy life. We examined the fruits and vegetables consumption by 240 caregivers and their children aged 1-17 years in peri-urban Lima, and the ways that they were incorporated into local cuisine. A randomized cross-sectional household survey collected information on the weight of all foods eaten the previous day (24 h) including fruits and vegetables, their preparation and serving sizes. Fruit and vegetable consumption was low and very variable: fruit intake was mean 185.2 ± 171.5 g day -1 , median 138 g day -1 for caregivers and 203.6 ± 190.6 g day -1 and 159 g day -1 for children, vegetable intake was mean 116.9 ± 94.0 g day -1 median 92 g day -1 for caregivers, mean 89.3 ± 84.7 g day -1 median 60 g day -1 for children. Only 23.8% of children and 26.2% of caregivers met the recommended ≥400 g of fruit or vegetable/day. Vegetables were mainly eaten either as ingredients of the main course recipe, eaten by about 80% of caregivers and children, or as salads eaten by 47% of caregivers and 42% of children. Fruits were most commonly eaten as whole fresh fruits eaten by 68% of caregivers and 75% of children. In multivariate analysis of the extent to which different presentations contributed to daily fruit and vegetable consumption, main courses contributed most to determining vegetable intake for caregivers, and for children, main course and salads had similar contributions. For fruit intake, the amount eaten as whole fruit determined total fruit and total fruit plus vegetable intake for both caregivers and children. Local cuisine should be considered in interventions to promote fruit and vegetable consumption. © 2016 John Wiley & Sons Ltd. © 2016 John Wiley & Sons Ltd.

Regulatory T cells (Tregs) are critical for development of oral tolerance, and studies suggest that dysfunction of Tregs may lead to food allergy. However, to date, no study has investigated Treg responses following in vivo exposure to peanut or egg allergens in humans. To examine changes in peripheral blood CD4(+) CD25(+) Foxp3(+) Treg populations (total, activated and naive) in food-allergic, food-sensitized but tolerant, and healthy (non-sensitized non-allergic) patients over time following in vivo allergen exposure. A subset of infants from the HealthNuts study with egg or peanut allergy (n = 37), egg or peanut sensitization (n = 35), or who were non-sensitized non-allergic (n = 15) were studied. All subjects underwent oral food challenge (OFC) to egg or peanut. PBMCs were obtained within 1 h of OFC (in vivo allergen exposure), and Treg populations enumerated ex vivo on day 0, and after 2 and 6 days rest in vitro. Non-allergic infants showed stable total Treg frequencies over time; food-sensitized infants had a transient fall in Treg percentage with recovery to baseline by day 6 (6.87% day 0, 5.27% day 2, 6.5% day 6); and food-allergic infants showed persistent reduction in Treg (6.85% day 0, 5.4% day 2, 6.2% day 6) following in vivo allergen exposure. Furthermore, food-allergic infants had a significantly lower ratio of activated Treg:activated T cells (10.5 ± 0.77) at day 0 compared to food-sensitized (14.6 ± 1.24) and non-allergic subjects (16.2 ± 1.23). Our data suggest that the state of allergen sensitization is associated with depletion of Treg following allergen exposure. Impaired capacity to regenerate the Treg pool following allergen exposure may be an important factor that determines clinical allergy vs. sensitization without allergic reaction. © 2015 John Wiley & Sons A/S.

Cholestatic itch can be severe and significantly impair the quality of life of patients. The serotonin system is implicated in cholestatic itch; however, the pruritogenic properties of serotonin have not been evaluated in cholestatic mice. Here, we investigated the serotonin-induced itch in cholestatic mice which was induced by bile duct ligation (BDL). Serotonin, sertraline or saline were administered intradermally to the rostral back area in BDL and sham operated (SHAM) mice, and the scratching behaviour was videotaped for 1 hour. Bile duct ligated mice had significantly increased scratching responses to saline injection on the seventh day after surgery. Additionally, serotonin or sertraline significantly induced scratching behaviour in BDL mice compared to saline at day 7 after surgery, while it did not induce itch at day 5. The scratching behaviour induced by serotonin or sertraline was significantly less in BDL mice compared to SHAM mice. Likewise, the locomotor activity of BDL or SHAM mice was not significantly different from unoperated (UNOP) mice on the fifth and seventh day, suggesting that the scratching behaviour was not affected by motor dysfunctions. Our data suggest that despite the potentiation of evoked itch, a resistance to serotonin-induced itch is developed in cholestatic mice. © 2017 John Wiley & Sons Australia, Ltd.

This study investigated the differentiation and proliferation of epithelial cells derived from periodontal ligaments after three-dimensional culture using collagen gel with fibroblasts in vitro and in vivo. Epithelial cells and fibroblasts were derived from porcine periodontal ligaments. Epithelial cells were labeled using a fluorescent red membrane marker (PKH-26GL) and were seeded onto collagen gel with fibroblasts, followed by incubation in an air-liquid interface for 7 days. Three-dimensional cultures were grafted onto the backs of nude mice and removed at 1, 7, and 14 days after surgery (in vivo model). Unfixed sections (5 μm) were used to detect the presence of red fluorescent cells. Paraffin sections were analyzed histologically and immunohistochemically. Specimens were compared with three-dimensional culture tissues at 8, 14 and 21 days (in vitro model). Grafted three-dimensional cultures formed a stratified epithelial structure similar to skin in vivo. Epithelial cells were sequenced in basal-layer-like structures at 14 days in vivo. Immunohistochemical findings showed that the expression of cytokeratin was detected in the epithelial layer in in vitro and in vivo models. Ck8 + 18 + 19 was expressed in the upper epithelial layer in the in vitro model at 14 and 21 days, but not in vivo. Involucrin was expressed in the certified layers in vitro at 14 days, but not in vivo. Laminin was detected at the dermo-epidermal junction in vivo at 7 and 14 days, but not in vitro. These results suggest that differentiation of three-dimensional culture tissues differs in vivo and in vitro. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To evaluate the clinical effects of different dosages of metronidazole (MTZ) and durations of MTZ + amoxicillin (AMX) in the treatment of generalized chronic periodontitis (GChP). Subjects with severe GChP were randomly assigned to receive scaling and root planing (SRP)-only, or combined with 250 or 400 mg of MTZ + AMX (500 mg) thrice a day (TID), for 7 or 14 days. Subjects were monitored for 1 year. One hundred and nine subjects were enrolled. At 1 year, 61.9% and 63.6% of the subjects receiving AMX + 250 or 400 mg of MTZ for 14 days, respectively, reached the clinical endpoint for treatment (≤4 sites with probing depth ≥5 mm), against 31.8% of those taking 250 or 400 mg of MTZ for 7 days (p < .05) and 13.6% of those receiving SRP-only (p < .05). Fourteen days of MTZ + AMX was the only significant predictor of subjects reaching the clinical endpoint at 1 year (OR, 5.26; 95% CI, 2.3-12.1, p = .0000). The frequency of adverse events did not differ among treatment groups (p > .05). The adjunctive use of 400 or 250 mg of MTZ plus 500 mg of AMX/TID/14 days offers statistically significant and clinically relevant benefits over those achieved with SRP alone in the treatment of severe GChP. The added benefits of the 7-days regimen in this population were less evident. (ClinicalTrials.gov NCT02735395). © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Escapement and Productivity of Spring Chinook Salmon and Summer Steelhead in the John Day River Basin, 2005-2006 Annual Technical Report.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Schultz, Terra Lang; Wilson, Wayne H.; Ruzycki, James R.

The objectives are: (1) Estimate number and distribution of spring Chinook salmon Oncorhynchus tshawytscha redds and spawners in the John Day River subbasin; and (2) Estimate smolt-to-adult survival rates (SAR) and out-migrant abundance for spring Chinook and summer steelhead O. mykiss and life history characteristics of summer steelhead. The John Day River subbasin supports one of the last remaining intact wild populations of spring Chinook salmon and summer steelhead in the Columbia River Basin. These populations, however, remain depressed relative to historic levels. Between the completion of the life history and natural escapement study in 1984 and the start ofmore » this project in 1998, spring Chinook spawning surveys did not provide adequate information to assess age structure, progeny-to-parent production values, smolt-to-adult survival (SAR), or natural spawning escapement. Further, only very limited information is available for steelhead life history, escapement, and productivity measures in the John Day subbasin. Numerous habitat protection and rehabilitation projects to improve salmonid freshwater production and survival have also been implemented in the basin and are in need of effectiveness monitoring. While our monitoring efforts outlined here will not specifically measure the effectiveness of any particular project, they will provide much needed background information for developing context for project-specific effectiveness monitoring efforts. To meet the data needs as index stocks, to assess the long-term effectiveness of habitat projects, and to differentiate freshwater and ocean survival, sufficient annual estimates of spawner escapement, age structure, SAR, egg-to-smolt survival, smolt-per-redd ratio, and freshwater habitat use are essential. We have begun to meet this need through spawning ground surveys initiated for spring Chinook salmon in 1998 and smolt PIT-tagging efforts initiated in 1999. Additional sampling and analyses to meet these goals include an estimate of smolt abundance and SAR rates, and an updated measure of the freshwater distribution of critical life stages. Because Columbia Basin managers have identified the John Day subbasin spring Chinook population as an index population for assessing the effects of alternative future management actions on salmon stocks in the Columbia Basin (Schaller et al. 1999) we continue our ongoing studies. This project is high priority based on the high level of emphasis the NWPPC Fish and Wildlife Program, Subbasin Summaries, NMFS, and the Oregon Plan for Salmon and Watersheds have placed on monitoring and evaluation to provide the real-time data to guide restoration and adaptive management in the region. By implementing the proposed program we have been able to address many of the goals for population status monitoring, such as defining areas currently used by spring Chinook for holding and spawning habitats and determining range expansion or contraction of summer rearing and spawning populations. The BiOp describes these goals as defining population growth rates (adult monitoring), detecting changes in those growth rates or relative abundance in a reasonable time (adult/juvenile monitoring), estimating juvenile abundance and survival rates (juvenile/smolt monitoring), and identifying stage-specific survival (adult-to-smolt, smolt-to-adult).« less

The bisphosphonate alendronate (ALN) was employed with the aim of investigating its effects on dental and periodontal tissues after lateral luxation of developing molars. Twenty-one-day-old Wistar rats had their second upper molars laterally luxated. Daily 2.5 mg kg(-1) ALN injections started at the day of the luxation; controls received sterile saline solution. The teeth were analyzed 7, 14, and 21 days after the procedure. On the days cited, the maxillae were fixed, decalcified, and embedded in paraffin or Spurr resin. The paraffin sections were stained with H&E, incubated for TRAP histochemistry or immunolabeled for osteopontin (OPN). Spurr ultrathin sections were examined in a transmission electron microscope. After 21 days, the root apex of luxated molars without ALN was wide open and disorganized and also covered by an irregular layer of cellular cementum, which was not observed in ALN-treated animals. Ankylosis sites were observed in ALN rats in both luxated and non-luxated teeth. The TRAP-positive osteoclasts were more numerous in ALN group, despite their latent ultrastructural appearance without the presence of resorption apparatus compared to controls. OPN immunolabeling revealed a thick immunopositive line in the dentin that must be resultant from the moment of the luxation, while ALN-treated specimens did not present alterations in dentin. The present findings indicate that alendronate inhibits some alterations in dentin and cementum formation induced by dental trauma. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The objective is to evaluate a body and movement-oriented intervention on aggression regulation, specifically aimed towards reducing anger internalization in patients with an eating disorder. Patients were randomized to treatment-as-usual (TAU) plus the intervention (n = 38) or to TAU only (n = 32). The intervention was delivered by a psychomotor therapist. TAU consisted of multidisciplinary day treatment (3-5 days per week during 3-9 months). Anger coping (Self-Expression and Control Scale) and eating pathology (Eating Disorder Examination-Self-report Questionnaire) were measured at baseline and follow-up. Differences between pre-intervention and post-intervention scores were tested by using repeated measures ANOVA. The intervention group showed a significantly larger decrease of anger internalization than the control group (η 2  = 0.16, p = 0.001). Both groups showed a significant reduction in eating pathology, but differences between groups were not significant. A body and movement-oriented therapy seems a viable add-on for treating anger internalization in patients with an eating disorder.

Bursch, Mario Runco, Jr., and Marc Garneau, Ph.D., perform a routine check of the shuttle's flight control surfaces and reaction control system jets, wrap up work with a number of scientific investigations, and begin securing the cabin for the trip back to Earth. Most experiments aboard the shuttle have been completed and stowed away, although a few will operate throughout the night and be deactivated once the crew wakes. Crew members Andy Thomas, a native of Australia, and Marc Garneau, a Canadian, each receive special greetings today as STS-77 nears its end. South Australia Premier Dean Brown called Thomas with congratulations early this morning as the shuttle passed above Brown's office in Adelaide, Australia, Thomas' hometown. Later, Canadian Prime Minister Jean Chretien called Garneau to congratulate him on the mission and the joint Canadian Space Agency and NASA experiments that were conducted.

Nocturnal and diurnal activity of armored suckermouth catfish (Loricariidae: Pterygoplichthys) associated with wintering Florida manatees (Trichechus manatus latirostris)

Nico, Leo G.

2010-01-01

Several Pterygoplichthys species, members of the Neotropical catfish family Loricariidae, have been widely introduced outside their native ranges. In this paper, I present observations on the diel activity pattern of non-native Pterygoplichthys, tentatively identified as P. disjunctivus, with respect to their attachment and grazing on endangered Florida manatees, Trichechus manatus latirostris. The study was conducted in December 2009 at Volusia Blue Spring, an artesianal spring system in the St. Johns River basin, Florida (USA). Supplemented by information gathered during previous visits to the spring site, this study revealed that adult Pterygoplichthys are active throughout the diel period (day, twilight and night). However, juvenile Pterygoplichthys were largely nocturnal and only at night did they consistently join adults in attaching to manatees. The juveniles generally remain hidden during the day, probably responding to presence of diurnal predators, mainly birds. Differences in diel behaviors among different Pterygoplichthys size classes in Florida are consistent with published observations on loricariids inhabiting clearwater streams within their native ranges.

Bloodstream infections (BSIs) and central line infections remain among the major causes of morbidity and mortality in transplant recipients because of prolonged neutropenia and mucosal damage. The objective of this study was to determine the frequency and outcome of bacterial and fungal isolates from patients undergoing allogeneic hematopoietic stem cell transplant. This study was conducted at the Aga Khan University and Hospital's bone marrow transplant unit. All patients who underwent an allogeneic stem cell transplant with matched sibling/parent donor were included. The study period ranged from April 2004 to December 2012. Transplantation was performed according to institutional protocols. All patients were admitted in single rooms with positive pressure and high-efficiency particulate air filters. Ciprofloxacin, fluconazole, and valaciclovir were used for standard prophylaxis, which was started at the time of conditioning. All blood cultures were obtained at clinical suspicion of systemic infection, mainly documented as fever (temperature of >38.5°C). BSIs and line infections were defined as isolation of bacterial or fungal pathogen from at least one blood/central line culture. In total, 101 of 108 patients developed febrile neutropenia. In the 101 patients, 245 documented febrile episodes occurred. There were 40 culture-positive episodes and 205 culture-negative episodes. Of these 40 culture-positive episodes, 22 patients had bloodstream isolates and 18 had central line isolates. The median ± standard deviation time of febrile neutropenia was day 7 ± 2 days (range: day -3 to day +13). The most common bloodstream isolate was Escherichia coli (n = 9) followed by Staphylococcus epidermidis (n = 5). One patient developed Fusarium infection. In central line infections, S. epidermidis was the most common organism (n = 8). In 2 patients with central venous catheters, Candida albicans was the isolate. Transplant-related mortality from sepsis occurred in 9.2%. E.coli was mainly responsible for BSI, while gram-positive organisms dominated catheter-related febrile episodes. Transplant-related mortality due to sepsis was 9%. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The generation of replacement inner ear hair cells (HCs) remains a challenge and stem cell therapy holds the potential for developing therapeutic solutions to hearing and balance disorders. Recent developments have made significant strides in producing mouse otic progenitors using cell culture techniques to initiate HC differentiation. However, no consensus has been reached as to efficiency and therefore current methods remain unsatisfactory. In order to address these issues, we compare the generation of otic and HC progenitors from embryonic stem (ES) cells in two cell culture systems: suspension vs. adherent conditions. In the present study, an ES cell line derived from an Atoh1-green fluorescent protein (GFP) transgenic mouse was used to track the generation of otic progenitors, initial HCs and to compare these two differentiation systems. We used a two-step short-term differentiation method involving an induction period of 5 days during which ES cells were cultured in the presence of Wnt/transforming growth factor TGF-β inhibitors and insulin-like growth factor IGF-1 to suppress mesoderm and reinforce presumptive ectoderm and otic lineages. The generated embryoid bodies were then differentiated in medium containing basic fibroblast growth factor (bFGF) for an additional 5 days using either suspension or adherent culture methods. Upon completion of differentiation, quantitative polymerase chain reaction analysis and immunostaining monitored the expression of otic/HC progenitor lineage markers. The results indicate that cells differentiated in suspension cultures produced cells expressing otic progenitor/HC markers at a higher efficiency compared with the production of these cell types within adherent cultures. Furthermore, we demonstrated that a fraction of these cells can incorporate into ototoxin-injured mouse postnatal cochlea explants and express MYO7A after transplantation.

Nuclear Rocket Technology Conference

NASA Technical Reports Server (NTRS)

1966-01-01

The Lewis Research Center has a strong interest in nuclear rocket propulsion and provides active support of the graphite reactor program in such nonnuclear areas as cryogenics, two-phase flow, propellant heating, fluid systems, heat transfer, nozzle cooling, nozzle design, pumps, turbines, and startup and control problems. A parallel effort has also been expended to evaluate the engineering feasibility of a nuclear rocket reactor using tungsten-matrix fuel elements and water as the moderator. Both of these efforts have resulted in significant contributions to nuclear rocket technology. Many successful static firings of nuclear rockets have been made with graphite-core reactors. Sufficient information has also been accumulated to permit a reasonable Judgment as to the feasibility of the tungsten water-moderated reactor concept. We therefore consider that this technoIogy conference on the nuclear rocket work that has been sponsored by the Lewis Research Center is timely. The conference has been prepared by NASA personnel, but the information presented includes substantial contributions from both NASA and AEC contractors. The conference excludes from consideration the many possible mission requirements for nuclear rockets. Also excluded is the direct comparison of nuclear rocket types with each other or with other modes of propulsion. The graphite reactor support work presented on the first day of the conference was partly inspired through a close cooperative effort between the Cleveland extension of the Space Nuclear Propulsion Office (headed by Robert W. Schroeder) and the Lewis Research Center. Much of this effort was supervised by Mr. John C. Sanders, chairman for the first day of the conference, and by Mr. Hugh M. Henneberry. The tungsten water-moderated reactor concept was initiated at Lewis by Mr. Frank E. Rom and his coworkers. The supervision of the recent engineering studies has been shared by Mr. Samuel J. Kaufman, chairman for the second day of the conference, and Mr. Roy V. Humble. Dr. John C. Eward served as general chairman for the conference.

Glucocorticoid (GC) is often given when preterm delivery is expected. This treatment is successful in stimulating the development of the fetal lung. However, reports and related research regarding the prolonged effects of prenatal GC on the development of immunity are very limited. Some data, derived from infants whose mothers were given immunosuppressants during pregnancy for the treatment of autoimmune disorders, suggest that prenatal exposure to GC may have only a limited effect on the development of the immune system. What is unknown is whether the immune modulation effects of prenatal GC might appear at a later childhood stage and beyond. Here we evaluated the immune programming influenced by prenatal GC. Pregnant Sprague-Dawley rats received dexamethasone (DEX; 0.1 mg/kg/day) or saline at gestational days 14-20. Male offspring were killed at day 7 or day 120 after birth. Spleens were collected for immune study. Of the inflammation mediators, matrix metalloproteinase-9, tumour necrosis factor-α (TNF-α) and granulocyte-macrophage colony-stimulating factor mRNAs decreased in the prenatal DEX group at an early stage after birth. Upon concanavalin A stimulation, prenatal DEX treatment reduced TNF-α production, but not interferon-γ production, by splenocytes at day 120 after birth compared with the vehicle group. Decreased levels of active chromatin signs (acetylation of histone H3 lysines, H3K4me1/3, and H3K36me3) in TNF-α promoter were compatible with the expressions of TNF-α. Our results suggest that prenatal DEX has a profound and lasting impact on the developing immune system even to the adult stage. Epigenetic histone modifications regulate TNF-α expression following prenatal DEX in rats. © 2014 John Wiley & Sons Ltd.

This study evaluated single dose and steady-state pharmacokinetics of fluvastatin following single and multiple dose administrations of a new extended release fluvastatin 8 h matrix tablet, Lescol XL 80 mg and 160 mg doses once a day. The study also included a twice a day administration of an immediate release (IR) form of fluvastatin capsule, Lescol, for comparative purposes. All doses were administered for 7 days. The safety and tolerability were also assessed. The pharmacokinetics of fluvastatin were evaluated on days 1 and 7 following each treatment. Fluvastatin systemic exposure was 50% less when administered as Lescol XL 80 mg qd compared with Lescol IR 40 mg bid. Conversely, fluvastatin systemic exposure was 22% higher when administered as Lescol XL 160 mg qd compared with Lescol IR 40 mg bid. Single doses of Lescol XL 80 mg and 160 mg were dose proportional but, deviation (30%) from dose proportionality was observed for the Lescol XL 160 mg at steady-state. There appeared to be moderate (20%-40%) accumulation of serum fluvastatin maximal concentrations and exposure after multiple doses of Lescol XL tablets. Both Lescol XL 80 mg and 160 mg showed delayed absorption and longer apparent elimination half-life compared with fluvastatin IR capsule. Single and multiple doses of fluvastatin were generally well tolerated in this healthy volunteer population. Adverse event profiles were consistent with the published safety profile of the marketed formulations. Aside from one incidence of creatine phosphokinase (CPK) elevation (following Lescol XL 160 mg qd treatment), there were no safety concerns with any of the treatments when administered acutely (7 days).

The advent of long-term remotely conducted clinical trials requires assessments which can be administered online. This paper considers the utility, reliability, sensitivity and validity of an internet-based system for measuring changes in cognitive function which is being used in one such trial. The Platform for Research Online to investigate Genetics and Cognition in Ageing is a 10-year longitudinal and entirely remote study launched in November 2015. The CogTrack TM System is being used to monitor changes in important aspects of cognitive function using tests of attention, information processing and episodic memory. On study entry, the participants performed CogTrack TM up to three times over seven days, and these data are evaluated in this paper. During the first six months of the study, 14 531 individuals aged 50 to 94 years enrolled and performed the CogTrack TM System, 8627 of whom completed three test sessions. On the first administration, 99.4% of the study tasks were successfully completed. Repeated testing showed training/familiarisation effects on four of the ten measures which had largely stabilised by the third test session. The factor structure of the various measures was found to be robust. Evaluation of the influence of age identified clinically relevant declines over the age range of the population on one or more measures from all tasks. The results of these analyses identify CogTrack TM to be a practical and valid method to reliably, sensitively, remotely and repeatedly collect cognitive data from large samples of individuals aged 50 and over.

In dogs, inflammatory mammary carcinoma is a clinicopathological entity characterized by rapid progression and aggressive behavior from onset of disease. Reported median survival time is short, with no effective treatment options. The aims of this prospective, noncontrolled clinical trial were to investigate outcome variables and safety profile of toceranib, thalidomide and piroxicam with or without hypofractionated radiation therapy in dogs with measurable histologically confirmed inflammatory mammary carcinoma that underwent a complete staging. Eighteen dogs were enrolled: 14 received medical treatment, and 4 were treated with hypofractionated radiation therapy and medical therapy. Overall, median time to progression was 34 days and median survival time was 109 days. In dogs treated with medical therapy, overall response rate was 21%, and clinical benefit rate (CBR) was 64%; median time to progression was 28 days and median survival time was 59 days. In dogs receiving medical therapy and undergoing radiation therapy, overall response rate and clinical benefit rate were 100%, with significantly longer time to progression (156 days) and survival time (180 days). Overall, treatment was well tolerated, with mild gastrointestinal and dermatological adverse events. Although the optimal treatment to this disease remains uncertain, the current approach consisting of systemic anti-angiogenic drugs with or without hypofractionated radiation therapy, provided clinical benefit in a significant proportion of dogs and should, therefore, be further explored. © 2018 John Wiley & Sons Ltd.

To assess whether the dual-hormone (insulin and glucagon) artificial pancreas reduces hypoglycaemia compared to the single-hormone (insulin alone) artificial pancreas in outpatient settings during the day and night. In a randomized, three-way, crossover trial we compared the dual-hormone artificial pancreas, the single-hormone artificial pancreas and sensor-augmented pump therapy (control) in 23 adults with type 1 diabetes. Each intervention was applied from 8 AM Day 1 to 8 PM Day 3 (60 hours) in outpatient free-living conditions. The primary outcome was time spent with sensor glucose levels below 4.0 mmol/L. A P value of less than .017 was regarded as significant. The median difference between the dual-hormone system and the single-hormone system was -2.3% (P = .072) for time spent below 4.0 mmol/L, -1.3% (P = .017) for time below 3.5 mmol/L, and -0.7% (P = .031) for time below 3.3 mmol/L. Both systems reduced (P < .017) hypoglycaemia below 4.0, 3.5 and 3.3 mmol/L compared to control therapy, but reductions were larger with the dual-hormone system than with the single-hormone system (medians -4.0% vs -3.4% for 4.0 mmol/L; -2.7% vs -2.2% for 3.5 mmol/L; and -2.2% vs -1.2% for 3.3 mmol/L). There were 34 hypoglycaemic events (<3.0 mmol/L for 20 minutes) with control therapy, 14 with the single-hormone system and 6 with the dual-hormone system. These differences in hypoglycaemia were observed while mean glucose level was low and comparable in all interventions (P = NS). The dual-hormone artificial pancreas had the lowest risk of hypoglycaemia, but the differences were not statistically significant. Larger studies are needed. © 2017 John Wiley & Sons Ltd.

Next-day residual effects of a nighttime dose of gabapentin 250 mg were evaluated on simulated driving performance in healthy participants in a randomized, placebo-controlled, double-blind, multicenter, four-period crossover study that included diphenhydramine citrate 76 mg and triazolam 0.5 mg. At treatment visits, participants (n = 59) were dosed at ~23:30, went to bed immediately, and awakened 6.5 h postdose for evaluation. The primary endpoint was the standard deviation of lateral position for the 100-km driving scenario. Additional measures of driving, sleepiness, and cognition were included. Study sensitivity was established with triazolam, which demonstrated significant next-day impairment on all driving endpoints, relative to placebo (p < 0.001). Gabapentin demonstrated noninferiority to placebo on standard deviation of lateral position and speed deviation but not for lane excursions. Diphenhydramine citrate demonstrated significant impairment relative to gabapentin and placebo on speed deviation (p < 0.05). Other comparisons were either nonsignificant or statistically ineligible per planned, sequential comparisons. Secondary endpoints for sleepiness and cognitive performance were supportive of these conclusions. Together, these data suggest that low-dose gabapentin had no appreciable next-day effects on simulated driving performance or cognitive functioning. Copyright © 2016 John Wiley & Sons, Ltd.

This article aims at evaluating indoor noise levels at home and investigating the factors that may influence their variability. An 8-day noise measurement campaign was conducted in the homes of 44 schoolchildren attending the public primary schools of Besançon (France). The presence of the inhabitants in the dwelling and the noisy events occurring indoors and outdoors was daily collected using a time-location-activity diary (TLAD); 902 time periods were analyzed. The indoor noise level increased significantly with the outdoor noise level, along with the duration of the presence or level of activity of the inhabitants at home. However, this effect may vary according to the period of day and the day of the week. Moreover, a significant part of the day and evening indoor noise level variability was explained when considering the TLAD variables: 46% and 45% in the bedroom, 54% and 39% in the main room, respectively. Our results highlight the complexity of the indoor environment in the dwellings of children living in an urban area. Combining the inhabitant presence and indoor noise source descriptors with outdoor noise levels and other dwelling or inhabitant characteristics could improve large-scale epidemiological studies. However, additional efforts are still needed, particularly during the night period. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To evaluate the inhibitory effects of the sports drink containing nano-sized hydroxyapatite (nano-HA) on dental erosion in situ. The study had a single-blind, two-treatment crossover design. The two treatment groups were a control group (CG; Powerade only) and an experimental group (EG; 0.25% wt/vol nano-HA was added to Powerade). Ten subjects wore removable palatal appliances containing bovine enamel specimens. The appliances were immersed in each drink for 10 mins, 4 times a day for 10 days. The tooth surface microhardness (SMH) was tested, and the erosion depth and the morphology of the tooth surface were observed. The data were analysed by repeated measures anova and t-test. Between the baseline and the 10th day, SMH was decreased by 80% in the specimens of the CG (P < 0.001), whereas there was only a 6% decrease in the SMH of the specimens in the EG. An erosion depth of 12.70 ± 4.66 μm and an irregular tooth surface were observed on the 10th day in the specimens of the CG. No dental erosions, however, was observed in the specimens of the EG. The sports drink containing 0.25% nano-HA was effective in preventing dental erosion in situ. © 2014 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

While Ayurvedic medicine has touted the cognitive enhancing effects of Bacopa monniera for centuries, there is a need for double-blind placebo-controlled investigations. One hundred and seven healthy participants were recruited for this double-blind placebo-controlled independent group design investigation. Sixty-two participants completed the study with 80% treatment compliance. Neuropsychological testing using the Cognitive Drug Research cognitive assessment system was conducted at baseline and after 90 days of treatment with a special extract of Bacopa monniera (2 x 150 mg KeenMind) or placebo. The Bacopa monniera product significantly improved performance on the 'Working Memory' factor, more specifically spatial working memory accuracy. The number of false-positives recorded in the Rapid visual information processing task was also reduced for the Bacopa monniera group following the treatment period. The current study provides support for the two other published studies reporting cognitive enhancing effects in healthy humans after a 90 day administration of the Bacopa monniera extract. Further studies are required to ascertain the effective dosage range, the time required to attain therapeutic levels and the effects over a longer term of administration.

2017-09-01

A thorough understanding of the role of human factors in error in health care for improving patient safely is paramount. One area particularly crucial for optimising clinical performance is the recognising the importance of situational awareness. Loss of situation awareness can occur in many different settings, particularly during stressful and unexpected situations. Tunnel vision is a classic example where clinicians focus on one aspect of care, often to the detriment of overall patient management. Loss of situational awareness can result in serious compromise to patient safety if it is not recognised by either the individual or clinical team. We provide an introduction to situational awareness for those not familiar with it, including some important theory which explains how awareness can be lost, and discuss the important approaches we use in our day-to-day practice to safeguard both patients and clinicians in the workplace environment. © 2016 John Wiley & Sons A/S.

Batten, J. H.; Peterson, B. V.; Berdis, E.; Wheeler, E. M.

1993-01-01

NASA's Controlled Ecological Life Support System (CELSS) biomass production chamber at John F. Kennedy Space Center provides a test bed for bioregenerative studies using plants to provide food, oxygen, carbon dioxide removal, and potable water to humans during long term space travel. Growing plants in enclosed environments has brought about concerns regarding the level of volatile organic compounds (VOC's) emitted from plants and the construction materials that make up the plant growth chambers. In such closed systems, the potential exists for some VOC's to reach toxic levels and lead to poor plant growth, plant death, or health problems for human inhabitants. This study characterized the air in an enclosed environment in which wheat cv. Yocora Rojo was grown. Ninty-four whole air samples were analyzed by gas chromatography/mass spectrometry throughout the eighty-four day planting. VOC emissions from plants and materials were characterized and quantified.

A forced-flow membrane reactor for transfructosylation using ceramic membrane.

Nishizawa, K; Nakajima, M; Nabetani, H

2000-04-05

A forced-flow membrane reactor system for transfructosylation was investigated using several ceramic membranes having different pore sizes. beta-Fructofuranosidase from Aspergillus niger ATCC 20611 was immobilized chemically to the inner surface of a ceramic membrane activated by a silane-coupling reagent. Sucrose solution was forced through the ceramic membrane by crossflow filtration while transfructosylation took place. The saccharide composition of the product, which was a mixture of fructooligosaccharides (FOS), was a function of the permeate flux, which was easily controlled by pressure. Using 0.2 micrometer pore size of symmetric ceramic membrane, the volumetric productivity obtained was 3.87 kg m(-3) s(-1), which was 560 times higher than that in a reported batch system, with a short residence time of 11 s. The half-life of the immobilized enzyme in the membrane was estimated to be 35 days by a long-term operation. Copyright 2000 John Wiley & Sons, Inc.

Water quality and ground-water/surface-water interactions along the John River near Anaktuvuk Pass, Alaska, 2002-2003

USGS Publications Warehouse

Moran, Edward H.; Brabets, Timothy P.

2005-01-01

The headwaters of the John River are located near the village ofAnaktuvuk Pass in the central Brooks Range of interior Alaska. With the recent construction of a water-supply system and a wastewater-treatment plant, most homes in Anaktuvuk Pass now have modern water and wastewater systems. The effluent from the treatment plant discharges into a settling pond near a tributary of the John River. The headwaters of the John River are adjacent to Gates of the Arctic National Park and Preserve, and the John River is a designated Wild River. Due to the concern about possible water-quality effects from the wastewater effluent, the hydrology of the John River near Anaktuvuk Pass was studied from 2002 through 2003. Three streams form the John River atAnaktuvuk Pass: Contact Creek, Giant Creek, and the John RiverTributary. These streams drain areas of 90.3 km (super 2) , 120 km (super 2) , and 4.6 km (super 2) , respectively. Water-qualitydata collected from these streams from 2002-03 indicate that the waters are a calcium-bicarbonate type and that Giant Creek adds a sulfate component to the John River. The highest concentrations of bicarbonate, calcium, sodium, sulfate, and nitrate were found at the John River Tributary below the wastewater-treatment lagoon. These concentrations have little effect on the water quality of the John River because the flow of the John River Tributary is only about 2 percent of the John River flow. To better understand the ground-water/surface-water interactions of the upper John River, a numerical groundwater-flow model of the headwater area of the John River was constructed. Processes that occur during spring break-up, such as thawing of the active layer and the frost table and the resulting changes of storage capacity of the aquifer, were difficult to measure and simulate. Application and accuracy of the model is limited by the lack of specific hydrogeologic data both spatially and temporally. However, during the mid-winter and open-water periods, the model provided acceptable results and was coupled with a particle-movement model to simulate the movement and possible extent of conservative particles from the wastewater-treatment-plant lagoon.

Collateral circulation secondary to liver cirrhosis may cause the development of large PSSs that may steal flow from the main portal circulation. It is important to identify these shunts prior to, or during the transplant surgery because they might cause an insufficient portal flow to the implanted graft. There are few reports of "steal flow syndrome" cases in pediatrics, even in biliary atresia patients that may have portal hypoplasia as an associated malformation. We present a 12-month-old female who received an uneventful LDLT from her mother, and the GRWR was 4.8. During the early post-operative period, she became hemodynamically unstable, developed ascites, and altered LFT. The post-operative ultrasound identified reversed portal flow, finding a non-anatomical PSS. A 3D CT scan confirmed the presence of a mesocaval shunt through the territory of the right gonadal vein, draining into the right iliac vein, with no portal inflow into the liver. The patient was re-operated, and the shunt was ligated. An intraoperative Doppler ultrasound showed adequate portal inflow after the procedure; the patient evolved satisfactorily and was discharged home on day number 49. The aim was to report a case of post-operative steal syndrome in a pediatric recipient due to a mesocaval shunt not diagnosed during the pretransplant evaluation. © 2018 John Wiley & Sons A/S.

Aerobic exercise training is a promising complementary treatment option in migraine and can reduce migraine days and improve retinal microvascular function. Our aim was to elucidate whether different aerobic exercise programs at high vs moderate intensities distinctly affect migraine days as primary outcome and retinal vessel parameters as a secondary. In this randomized controlled trial, migraine days were recorded by a validated migraine diary in 45 migraineurs of which 36 (female: 28; age: 36 (SD:10)/BMI: 23.1 (5.3) completed the training period (dropout: 20%). Participants were assigned (Strata: age, gender, fitness and migraine symptomatology) to either high intensity interval training (HIT), moderate continuous training (MCT), or a control group (CON). Intervention groups trained twice a week over a 12-week intervention period. Static retinal vessel analysis, central retinal arteriolar (CRAE) and venular (CRVE) diameters, as well as the arteriolar-to-venular diameter ratio (AVR) were obtained for cerebrovascular health assessment. Incremental treadmill testing yielded maximal and submaximal fitness parameters. Overall, moderate migraine day reductions were observed (ηP2 = .12): HIT revealed 89% likely beneficial effects (SMD = 1.05) compared to MCT (SMD = 0.50) and CON (SMD = 0.59). Very large intervention effects on AVR improvement (ηP2 = 0.27), slightly favoring HIT (SMD=-0.43) over CON (SMD=0), were observed. HIT seems more effective for migraine day reduction and improvement of cerebrovascular health compared to MCT. Intermittent exercise programs of higher intensities may need to be considered as an additional treatment option in migraine patients. © 2017 John Wiley & Sons A/S.

Physical inactivity leads to a cluster of metabolic disorders that have been associated with non-alcoholic fatty liver diseases. We tested whether physical inactivity increases hepatic biomarkers of NAFLDs. Sixteen normal-weight healthy women (body mass index = 21.2 ± 0.5 kg/m(2) ) were studied under controlled energy balance conditions during a previous 60-day bed rest with (n = 8) or without (n = 8) a combined aerobic/resistive exercise protocol. Stored samples were retrospectively used to measure plasma hepatic markers, i.e. steatosis-related alanine and aspartate transaminases, cytokeratin 18 and angiopoietin-like 3, at baseline, after 30 and 60 days of bed rest. Fasting insulin and triglycerides were measured at baseline and after 30 days of bed rest. Two indexes were calculated, one combining alanine and aspartate transaminase and cytokeratin 18 and another cytokeratin 18, homeostasis model assessment of insulin resistance and aspartate aminotransferase. Sixty days of bed rest increased all hepatic markers (P < 0.05 for all) and the two indexes (P < 0.01 for both). Exercise significantly reduced the elevation in aspartate transaminase, cytokeratin 18 and both indexes (P < 0.02 for all) but not the increase in alanine transaminase and angiopoietin-like 3. Changes between baseline and 30 days of bed rest in triglycerides were positively associated with changes in aspartate transaminase (R(2) = 0.28, P = 0.04) suggesting a role of hypertriglyceridaemia in the alteration of liver metabolism under inactive conditions. Physical inactivity increases, independent of fat mass, hepatic markers of steatosis and steatohepatitis. Regular exercise can limit these physical inactivity-induced metabolic alterations. Future studies need to elucidate the underlying mechanisms. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

This study examines the relationship of asthma emergency department (ED) visits to daily concentrations of ozone and other air pollutants in Saint John, New Brunswick, Canada. Data on ED visits with a presenting complaint of asthma (n = 1987) were abstracted for the period 1984-1992 (May-September). Air pollution variables included ozone, sulfur dioxide, nitrogen dioxide, sulfate, and total suspended particulate (TSP); weather variables included temperature, humidex, dewpoint, and relative humidity. Daily ED visit frequencies were filtered to remove day of the week and long wave trends, and filtered values were regressed on air pollution and weather variables for the same day and the 3 previous days. The mean daily 1-hr maximum ozone concentration during the study period was 41.6 ppb. A positive, statistically significant (p < 0.05) association was observed between ozone and asthma ED visits 2 days later, and the strength of the association was greater in nonlinear models. The frequency of asthma ED visits was 33% higher (95% CI, 10-56%) when the daily 1-hr maximum ozone concentration exceeded 75 ppb (the 95th percentile). The ozone effect was not significantly influenced by the addition of weather or other pollutant variables into the model or by the exclusion of repeat ED visits. However, given the limited number of sampling days for sulfate and TSP, a particulate effect could not be ruled out. We detected a significant association between ozone and asthma ED visits, despite the vast majority of sampling days being below current U.S. and Canadian standards. Images Figure 1. A Figure 1.

Objectives In this report, we review Dr. Cushing's early surgical cases at the Johns Hopkins Hospital, revealing details of his early operative approaches to infections of the skull base. Design Following institutional review board (IRB) approval, and through the courtesy of the Alan Mason Chesney Archives, we reviewed the Johns Hopkins Hospital surgical files from 1896 to 1912. Setting The Johns Hopkins Hospital, 1896 to 1912. Participants Eleven patients underwent operative treatment for suspected infections of the skull base. Main Outcome Measures The main outcome measure was operative approach, postoperative mortality, and condition recorded at the time of discharge. Results Eleven patients underwent operative intervention for infections of the skull base. The mean age was 30 years (range: 9 to 63). Of these patients, seven (64%) were female. The mean length of stay was 16.5 days (range: 4 to 34). Postoperatively eight patients were discharged in “well” or “good” condition, one patient remained “unimproved,” and two patients died during their admission. Conclusion Cushing's careful preoperative observation of patients, meticulous operative technique, and judicious use of postoperative drainage catheters contributed to a remarkably low mortality rate in his series of skull base infections.

To evaluate the safety and performance of using a heart rate (HR) monitor to inform an artificial pancreas (AP) system during exercise among adolescents with type 1 diabetes (T1D). In a randomized, cross-over trial, adolescents with T1D age 13 - 18 years were enrolled to receive on separate days either the unmodified UVa AP (stdAP) or an AP system connected to a portable HR monitor (AP-HR) that triggered an exercise algorithm for blood glucose (BG) control. During admissions participants underwent a structured exercise regimen. Hypoglycemic events and CGM tracings were compared between the two admissions, during exercise and for the full 24-hour period. Eighteen participants completed the trial. While number of hypoglycemic events during exercise and rest was not different between visits (0.39 AP-HR vs 0.50 stdAP), time below 70 mg dL -1 was lower on AP-HR compared to stdAP, 0.5±2.1% vs 7.4±12.5% (P = 0.028). Time with BG within 70-180 mg dL -1 was higher for the AP-HR admission vs stdAP during the exercise portion and overall (96% vs 87%, and 77% vs 74%), but these did not reach statistical significance (P = 0.075 and P = 0.366). Heart rate signals can safely and efficaciously be integrated in a wireless AP system to inform of physical activity. While exercise contributes to hypoglycemia among adolescents, even when using an AP system, informing the system of exercise via a HR monitor improved time <70 mg dL -1 . Nonetheless, it did not significantly reduce the total number of hypoglycemic events, which were low in both groups. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Development of a System-Wide Predator Control Program: Stepwise Implementation of a Predation Index, Predator Control Fisheries, and Evaluation Plan in the Columbia River Basin; Northern Pikeminnow Management Program, 2002 Annual Report.

Porter, Russell G.; Winther, Eric C.; Fox, Lyle G.

This report presents results for year twelve in a basin-wide program to harvest northern pikeminnow1 (Ptychocheilus oregonensis). This program was started in an effort to reduce predation by northern pikeminnow on juvenile salmonids during their emigration from natal streams to the ocean. Earlier work in the Columbia River Basin suggested predation by northern pikeminnow on juvenile salmonids might account for most of the 10-20% mortality juvenile salmonids experience in each of eight Columbia River and Snake River reservoirs. Modeling simulations based on work in John Day Reservoir from 1982 through 1988 indicated that, if predator-size northern pikeminnow were exploited atmore » a 10-20% rate, the resulting restructuring of their population could reduce their predation on juvenile salmonids by 50%. To test this hypothesis, we implemented a sport-reward angling fishery and a commercial longline fishery in the John Day Pool in 1990. We also conducted an angling fishery in areas inaccessible to the public at four dams on the mainstem Columbia River and at Ice Harbor Dam on the Snake River. Based on the success of these limited efforts, we implemented three test fisheries on a system-wide scale in 1991--a tribal longline fishery above Bonneville Dam, a sport-reward fishery, and a dam-angling fishery. Low catch of target fish and high cost of implementation resulted in discontinuation of the tribal longline fishery. However, the sport-reward and dam-angling fisheries were continued in 1992 and 1993. In 1992, we investigated the feasibility of implementing a commercial longline fishery in the Columbia River below Bonneville Dam and found that implementation of this fishery was also infeasible. Estimates of combined annual exploitation rates resulting from the sport-reward and damangling fisheries remained at the low end of our target range of 10-20%. This suggested the need for additional effective harvest techniques. During 1991 and 1992, we developed and tested a modified (small-sized) Merwin trapnet. We found this floating trapnet to be very effective in catching northern pikeminnow at specific sites. Consequently, in 1993 we examined a system-wide fishery using floating trapnets, but found this fishery to be ineffective at harvesting large numbers of northern pikeminnow on a system-wide scale.« less

Culturing muscle fibres in hanging drop: a novel approach to solve an old problem.

The satellite cells (SCs) associated with muscle fibres play a key role in postnatal growth and regeneration of skeletal muscle. Commonly used methods of isolation and in vitro culture of SCs lead to the mixture of their subpopulations that exist within muscle. To solve this problem, we used the well established technique, the hanging drop system, to culture SCs in a three-dimensional environment and thus, to monitor them in their original niche. Using hanging drop technique, we were able to culture SCs associated with the fibre at least for 9 days with one transfer of fibres to the fresh drops. In comparison, in the classical method of myofibres culture, that is, on the dishes coated with Matrigel, SCs leave the fibres within 3 days after the isolation. Cells cultured in both systems differed in expression of Pax7 and MyoD. While almost all cells cultured in adhesion system expressed MyoD before the fifth day of the culture, the majority of SCs cultured in hanging drop still maintained expression of Pax7 and were not characterised by the presence of MyoD. Among the cells cultured with single myofibre for up to 9 days, we identified two different subclones of SCs: low proliferative clone and high proliferative clone, which differed in proliferation rate and membrane potential. The hanging drop enables the myofibres to be kept in suspension for at least 9 days, and thus, allows SCs and their niche to interact each other for prolonged time. In a consequence, SCs cultured in hanging drop maintain expression of Pax7 while those cultured in a traditional adhesion culture, that is, devoid of signals from the original niche, activate and preferentially undergo differentiation as manifested by expression of MyoD. Thus, the innovative method of SCs culturing in the hanging drop system may serve as a useful tool to study the fate of different subpopulations of these cells in their anatomical location and to determine reciprocal interactions between them and their niche. © 2013 Société Française des Microscopies and Société de Biologie Cellulaire de France.

The intradermal (ID) route for vaccination represents an effective alternative to subcutaneous (SC)/intramuscular administration to induce protective immunity. However, a critical issue associated with ID vaccination is the precise delivery of solution in the upper dermis, which ensures enhanced immunity. We fabricated a hollow microneedle unit made of poly-glycolic acid by injection molding and bonding, and created a dedicated prototype injector. To ensure ID delivery of solution, the injected site was macroscopically and microscopically examined. Serum immunoglobulin G antibody production was measured by enzyme immunoassay and compared in groups of rats following either ID delivery with microneedles or SC administration with a 27-G stainless needle of graded vaccine doses. The unit used a tandem array of six microneedles, each with a side delivery hole, and a conduit inside for solution. Microneedles installed in the injector punctured the skin with the aid of a spring. Injection of solution formed a wheal due to ID distribution. Histologically, a wedge-shaped skin defect in the upper skin corresponded to each puncture site. Antibody titers following vaccinations on days 1 and 8 were significantly higher with ID injection than with SC delivery on day 15 and every 7 days thereafter until day 36 with mumps vaccination, and until day 36 with varicella vaccination. The microneedle unit presented here delivered solution intradermally without any difficulty and evoked antibody responses against viruses even with the reduced vaccine volume. Our findings confirm promising results of ID delivery as an immunogenic option to enhance vaccination efficacy. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Clostridium difficile infection (CDI) is a common complication of lung and allogeneic hematopoietic cell (HCT) transplant, but the epidemiology and outcomes of CDI after transplant are poorly described. We performed a prospective, multicenter study of CDI within 365 days post-allogeneic HCT or lung transplantation. Data were collected via patient interviews and medical chart review. Participants were followed weekly in the 12 weeks post-transplant and while hospitalized and contacted monthly up to 18 months post-transplantation. Six sites participated in the study with 614 total participants; 4 enrolled allogeneic HCT (385 participants) and 5 enrolled lung transplant recipients (229 participants). One hundred and fifty CDI cases occurred within 1 year of transplantation; the incidence among lung transplant recipients was 13.1% and among allogeneic HCTs was 31.2%. Median time to CDI was significantly shorter among allogeneic HCT than lung transplant recipients (27 days vs 90 days; P = .037). CDI was associated with significantly higher mortality from 31 to 180 days post-index date among the allogeneic HCT recipients (Hazard ratio [HR] = 1.80; P = .007). There was a trend towards increased mortality among lung transplant recipients from 120 to 180 days post-index date (HR = 4.7, P = .09). The epidemiology and outcomes of CDI vary by transplant population; surveillance for CDI should continue beyond the immediate post-transplant period. © 2018 John Wiley & Sons A/S.

Post-operative sepsis considerably increases mortality, but the extent of pre-operative sepsis in hip fracture patients and its consequences are sparsely elucidated. The aim of this study was to assess the association between pre-operative sepsis and 30-day mortality after hip fracture surgery. We conducted a retrospective analysis of data collected among 1894 patients who underwent hip fracture surgery in the Capital Region of Denmark in 2014 (NCT03201679). Data on vital signs, cultures and laboratory data were obtained. Sepsis was defined as a positive culture of any kind and presence of systemic inflammatory response syndrome within 24 hours and was assessed within 72 hours before surgery and 30 days post-operatively. Primary outcome was 30-day mortality. Secondary outcomes included length of hospital stay and admission to intensive care unit. A total of 144 (7.6%) of the hip fracture patients met the criteria for pre-operative sepsis. The 30-day mortality was 13.9% in patients with pre-operative sepsis as compared to 9.0% in those without (OR 1.69, 95% CI [1.00; 2.85], P = .08). Patients with pre-operative sepsis had longer hospital stays (median 10 days vs 9 days, mean difference 2.1 [SD 9.4] days, P = .03), and higher frequency of ICU admission (11.1% vs 2.7%, OR 4.15, 95% CI [2.19; 7.87], P < .0001). Pre-operative sepsis in hip fracture patients was associated with an increased length of hospital stay and tended to increase mortality. Pre-operative sepsis in hip fracture patients merits more intensive surveillance and increased attention to timely treatment. © 2018 The Acta Anaesthesiologica Scandinavica Foundation.

Dispersion development program. [development of a fin stabilized submissile and ejection system for the Little John warhead

NASA Technical Reports Server (NTRS)

Carlson, D. J.; Lusardi, R. J.; Phillips, W. H.

1975-01-01

The requirement for the predictable dispersion of small munitions over large areas from ground support missile systems has resulted in the development of a fin stabilized submissile and sling ejection system for the Little John warhead. The progressive development of this system is traced including a comparison of simulator, sled test, and flight test results. The results indicate that it is not only necessary but also possible to eject long slender bodies, from a missile warhead at Mach 1, in a stable, uniform and predictable manner.

In Study 1, 77 children in Grades 3 and 6 were asked to draw pictures of the three major Presidential candidates (John Anderson, Jimmy Carter, and Ronald Reagan) at 2-wk. intervals beginning October 1, 1980 (about five weeks before Election Day) and ending November 12, 1980 (about one week after Election Day). It was hypothesized that the pictures would increase in size until Election Day and decrease thereafter. Drawings of Carter and Reagan decreased after Election Day, while those of Anderson began decreasing three weeks before the election. In Study 2, 81 children in Grades 4 and 5 drew pictures of Ronald Reagan and Walter Mondale at 2-wk. intervals during the 1984 Presidential campaign. Drawings of Reagan decreased in size after Election Day but not those of Mondale.

Several studies have demonstrated the time course of inflammatory mediators in nasal fluids following nasal allergen challenge (NAC), whereas the effects of NAC on cells in the periphery are unknown. We examined the time course of effector cell markers (for basophils, dendritic cells and T cells) in peripheral blood after nasal grass pollen allergen challenge. Twelve participants with seasonal allergic rhinitis underwent a control (diluent) challenge followed by NAC after an interval of 14 days. Nasal symptoms and peak nasal inspiratory flow (PNIF) were recorded along with peripheral basophil, T-cell and dendritic cell responses (flow cytometry), T-cell proliferative responses (thymidine incorporation), and cytokine expression (FluoroSpot assay). Robust increases in nasal symptoms and decreases in PNIF were observed during the early (0-1 h) response and modest significant changes during the late (1-24 h) response. Sequential peaks in peripheral blood basophil activation markers were observed (CD107a at 3 h, CD63 at 6 h, and CD203c(bright) at 24 h). T effector/memory cells (CD4(+) CD25(lo) ) were increased at 6 h and accompanied by increases in CD80(+) and CD86(+) plasmacytoid dendritic cells (pDCs). Ex vivo grass antigen-driven T-cell proliferative responses and the frequency of IL-4(+) CD4(+) T cells were significantly increased at 6 h after NAC when compared to the control day. Basophil, T-cell, and dendritic cell activation increased the frequency of allergen-driven IL-4(+) CD4(+) T cells, and T-cell proliferative responses are detectable in the periphery after NAC. These data confirm systemic cellular activation following a local nasal provocation. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Palliative care inpatient units (PCUs) can improve symptoms, family perception of care, and lower per-diem costs compared with usual care. In March 2013, Johns Hopkins Medical Institutions (JHMI) added a PCU to the palliative care (PC) program. We studied the financial impact of the PC program on JHMI from March 2013 to March 2014. This study considered three components of the PC program: PCU, PC consultations, and professional fees. Using 13 months of admissions data, the team calculated the per-day variable cost pre-PCU (ie, in another hospital unit) and after transfer to the PCU. These fees were multiplied by the number of patients transferred to the PCU and by the average length of stay in the PCU. Consultation savings were estimated using established methods. Professional fees assumed a collection rate of 50%. The total positive financial impact of the PC program was $3,488,863.17. There were 153 transfers to the PCU, 60% with cancer, and an average length of stay of 5.11 days. The daily loss pretransfer to the PCU of $1,797.67 was reduced to $1,345.34 in the PCU (-25%). The PCU saved JHMI $353,645.17 in variable costs, or $452.33 per transfer. Cost savings for PC consultations in the hospital, 60% with cancer, were estimated at $2,765,218. $370,000 was collected in professional fees savings. The PCU and PC program had a favorable impact on JHMI while providing expert patient-centered care. As JHMI moves to an accountable care organization model, value-based patient-centered care and increased intensive care unit availability are desirable.

We sought to analyse the effect of pretransplant diabetes on post-operative outcomes and resource utilization following liver transplantation. A retrospective cohort study was designed using a linkage between the University HealthSystem Consortium and Scientific Registry of Transplant Recipients databases. We identified 12 442 patients who underwent liver transplantation at 63 centres from 2007-2011 and separated cohorts of patients with diabetes (n = 2971; 24%) and without (n = 9471; 76%) at the time of transplant. We analysed transplant related outcomes and short-term survival. Diabetic recipients were more likely to be male (70% vs 67%), non-white (32% vs 26%), older (age ≥60; 41% vs 28%), and have a higher BMI (29 vs 27; P < 0.001). More diabetic patients were on haemodialysis (10% vs 7%), had cirrhosis caused by NASH (24% vs 9%; P < 0.001), and received liver allografts from older donors (≥ 60 years; 19% vs 15%) with a higher donor risk index (>1.49; 46% vs 42%; P < 0.001). Post-transplant, diabetic recipients had longer hospital length of stay (10 vs 9 days), higher peri-transplant mortality (5% vs 4%) and 30-day readmission rates (41% vs 37%), were less often discharged to home (83% vs 87%; P < 0.05), and had inferior graft and patient survival. Liver transplant was more expensive for type 1 vs type 2 diabetics ($105 078 vs $100 624, P < 0.001). Poorly controlled diabetic recipients were less likely discharged home following transplant (75% vs 82%, P < 0.01). This national study indicates that pretransplant diabetes is associated with inferior post-operative outcomes and increased resource utilization after liver transplantation. © 2014 John Wiley & Sons A/S.

Concomitant renin-angiotensin-aldosterone system blockade and natriuretic peptide system enhancement may provide unique therapeutic benefits to patients with heart failure and reduced ejection fraction (HFrEF). This study assessed the pharmacodynamics and pharmacokinetics of LCZ696 in patients with HFrEF. This was an open-label, noncontrolled single-sequence study. After a 24-h run-in period, patients (n = 30) with HFrEF (EF ≤ 40%; NYHA class II-IV) received LCZ696 100 mg twice daily (bid) for 7 days and 200 mg bid for 14 days, along with standard treatment for heart failure (HF) (except angiotensin-converting enzyme inhibitors [ACEIs] or angiotensin receptor blockers [ARBs]). On Day 21, significant increases were observed in the plasma biomarkers indicative of neprilysin and RAAS inhibition (ratio-to-baseline: cyclic guanosine monophosphate [cGMP], 1.38; renin concentration and activity, 3.50 and 2.27, respectively; all, P < 0.05). Plasma NT-proBNP levels significantly decreased at all the time points on Days 7 and 21; plasma aldosterone and endothelin-1 levels significantly decreased on Day 21 (all, P < 0.05). Following administration of LCZ696, the Cmax of sacubitril (neprilysin inhibitor prodrug), LBQ657 (active neprilysin inhibitor), and valsartan were reached within 0.5, 2.5, and 2 h. Between 100- and 200-mg doses, the Cmax and AUC0-12 h for sacubitril and LBQ657 were approximately dose-proportional while that of valsartan was less than dose-proportional. Treatment with LCZ696 for 21 days was well tolerated and resulted in plasma biomarker changes indicative of neprilysin and RAAS inhibition in patients with HF. The pharmacokinetic exposure of the LCZ696 analytes in patients with HF observed in this study is comparable to that observed in the pivotal Phase III study. © 2016 John Wiley & Sons Ltd.

Several studies have attempted to prevent or improve oral mucositis (OM) but have not produced a qualified treatment yet. This study evaluates the effects of Carum carvi L. (caraway) hydroalcoholic extract (CHE) as one of the traditional medicinal plants in 5-fluorouracil (5-FU)-induced OM in golden hamsters. OM was induced in 54 male golden hamsters by 5-FU and cheek pouch scratching. Starting from day 12, 500 and 1000 mg kg(-1) per day topical CHE were administered. Pouch histopathology score, malondialdehyde and reduced glutathione contents, and activity of myeloperoxidase plus microbial cultures of cheek pouch, antimicrobial properties of CHE, and essential oil constituents were evaluated. Lower histopathology score (0, 1, and 2) and malondialdehyde level, higher reduced glutathione level and activities of myeloperoxidase were detected in 1000 and 500 mg kg(-1) per day topical CHE and control groups, respectively (P < 0.001). The CHE was more potent against Staphylococcus epidermidis and Streptococcus intermedius. γ-Terpinene (37.2%) was identified as the main constituent of essential oil. The use of CHE in topical form may be associated with reduced intensity of OM. This may be due to appropriate antibacterial activity and terpinene contents. © 2015 John Wiley & Sons A/S.

This randomized controlled clinical trial evaluated the effects of an adjunctive single application of antimicrobial photodynamic therapy (aPDT) in Surgical Periodontal Treatment (ST) in patients with severe chronic periodontitis (SCP). In a split-mouth design, 20 patients with SCP were treated with aPDT+ST (Test Group, TG) or ST only (Control Group, CG). aPDT was applied in a single episode, using a diode laser and a phenothiazine photosensitizer. All patients were monitored until 90 days after surgical therapy. Levels of 40 subgingival species were measured by checkerboard DNA-DNA hybridization at baseline, 60 and 150 days. Clinical and microbiological parameters were evaluated. In deep periodontal pockets depth (PPD ≥5 mm), Test Group presented a significantly higher decrease in PPD than Control Group at 90 days after surgical therapy (p < .05). Test Group also demonstrated significantly less periodontal pathogens of red complex (Treponema denticola) (p < .05). A single episode of aPDT used in adjunct to open flap debridement of the root surface in the surgical treatment of SCP: i) significantly improved clinical periodontal parameters; ii) eliminates periodontal pathogens of the red complex more effectively (NCT02734784). © 2017 John Wiley & Sons A/S.

Metabolic syndrome (MetS) is defined by a clustering of metabolic and anthropometric abnormalities and is associated by an increased risk of cardiovascular disease. We have investigated the effect of curcumin supplementation on the serum pro-oxidant-antioxidant balance (PAB) in patients with MetS. This double-blind, randomized, placebo-controlled trial was conducted over 6 weeks. Subjects (n = 120) were randomly allocated to one of three groups (curcumin, phospholipidated curcumin, and placebo). The curcumin group received 1 g/day of simple curcumin, the phospholipidated curcumin group received 1 g/day of phospholipidated curcumin (containing 200 mg of pure curcumin), and the control group received 1 g/day of placebo. Serum PAB was measured before and after the intervention (at baseline and at 6 weeks). Data analyses were performed using spss software (version 16.0). Serum PAB increased significantly in the curcumin group (p < 0.001), but in the phospholipidated curcumin group, elevation of PAB level was not significant (p = 0.053). The results of our study did not suggest any improvement of PAB following supplementation with curcumin in MetS subjects. Copyright © 2017 John Wiley & Sons, Ltd.

Assessment of the effect of non-surgical periodontal therapy (SRP) on serum inflammatory parameters in patients with untreated aggressive (AgP) and chronic (ChP) periodontitis. Overall, 31 ChP and 29 AgP were examined clinically prior to and 12 weeks after SRP (subgingival scaling of all pockets within 2 days) with systemic antibiotics for patients positive for Aggregatibacter actinomycetemcomitans (14 AgP, 9 ChP). Blood was sampled prior to, one day, 6, and 12 weeks after the first SRP visit. Serum elastase, C-reactive protein (CRP), lipopolysaccharide-binding protein (LBP), interleukin (IL) 6, 8, and leukocyte counts were assessed. At baseline, serum elastase, CRP, and LBP were significantly (p < 0.01) higher in AgP than ChP. Serum elastase, CRP, LBP, and IL-6 were significantly (p < 0.001) elevated one day after scaling in both groups. Both groups showed significant clinical improvement (p < 0.001). A significant difference was observed regarding change of serum elastase 12 weeks after SRP between AgP and ChP (p = 0.015). Multiple regression analysis revealed AgP, African origin, and bleeding on probing to be associated with more pronounced elastase reduction. CRP reduction was associated with African origin, systemic antibiotics, and baseline probing pocket depth. SRP results in serum elastase reduction in AgP but not in ChP. © 2013 John Wiley & Sons A/S.

The Nez Perce Tribe, in cooperation with the U.S. Fish and Wildlife Service and Washington Department of Fish and Wildlife, conducted monitoring and evaluation studies on Lyons Ferry Hatchery reared yearling fall Chinook salmon Oncorhynchus tshawytscha that were acclimated and released at three Fall Chinook Acclimation Project sites upstream of Lower Granite Dam along with yearlings released on-station from Lyons Ferry Hatchery in 2001. This was the sixth year of a long-term project to supplement natural spawning populations of Snake River stock fall Chinook salmon upstream of Lower Granite Dam. The 318,932 yearlings released from the Fall Chinook Acclimation Projectmore » facilities were short of the 450,000 fish quota. We use Passive Integrated Transponder (PIT) tag technology to monitor the primary performance measures of survival to mainstem dams and migration timing. We also monitor size, condition and tag/mark retention at release. We released 7,503 PIT tagged yearlings from Pittsburg Landing, 7,499 from Big Canyon and 2,518 from Captain John Rapids. The Washington Department of Fish and Wildlife released 991 PIT tagged yearlings from Lyons Ferry Hatchery. Fish health sampling indicated that, overall, bacterial kidney disease levels could be considered relatively low. Compared to prior years, Quantitative Health Assessment Indices were relatively low at Big Canyon and Captain John Rapids and about average at Pittsburg Landing and Lyons Ferry Hatchery. Mean fork lengths (95% confidence interval) of the PIT tagged groups ranged from 155.4 mm (154.7-156.1 mm) at Captain John Rapids to 171.6 mm (170.7-172.5 mm) at Lyons Ferry Hatchery. Mean condition factors ranged from 1.02 at Lyons Ferry Hatchery to 1.16 at Big Canyon and Captain John Rapids. Estimated survival (95% confidence interval) of PIT tagged yearlings from release to Lower Granite Dam ranged from 74.4% (73.2-75.5%) for Big Canyon to 85.2% (83.5-87.0%) for Captain John Rapids. Estimated survival from release to McNary Dam ranged from 37.9% (36.0-40.0%) for Pittsburg Landing to 57.9% (53.0-62.8%) for Lyons Ferry Hatchery. Median migration rates to Lower Granite Dam, based on all observations of PIT tagged yearlings from the FCAP facilities, ranged from 6.3 river kilometers per day (rkm/d) for Big Canyon to 10.8 rkm/d for Pittsburg Landing. Median migration rates to McNary Dam ranged from 5.2 rkm/d for Lyons Ferry Hatchery to 10.9 rkm/d for Pittsburg Landing. Median travel times from the FCAP facilities were about 13-17 days to Lower Granite Dam and 31-37 days to McNary Dam. Median arrival dates at Lower Granite Dam, based on all observations of PIT tagged yearling groups from Pittsburg Landing, Big Canyon and Captain John Rapids, were all from April 26-27. Median arrival dates at McNary Dam for Pittsburg Landing, Big Canyon and Captain John Rapids groups were all from May 14-18. The median arrival date at McNary Dam was May 13 for Lyons Ferry Hatchery yearlings.« less

Discerning network interactions among different species/populations in microbial communities has evoked substantial interests in recent years, but little information is available about temporal dynamics of microbial network interactions in response to environmental perturbations. Here, we modified the random matrix theory-based network approach to discern network succession in groundwater microbial communities in response to emulsified vegetable oil (EVO) amendment for uranium bioremediation. Groundwater microbial communities from one control and seven monitor wells were analysed with a functional gene array (GeoChip 3.0), and functional molecular ecological networks (fMENs) at different time points were reconstructed. Our results showed that the network interactions were dramatically altered by EVO amendment. Dynamic and resilient succession was evident: fairly simple at the initial stage (Day 0), increasingly complex at the middle period (Days 4, 17, 31), most complex at Day 80, and then decreasingly complex at a later stage (140-269 days). Unlike previous studies in other habitats, negative interactions predominated in a time-series fMEN, suggesting strong competition among different microbial species in the groundwater systems after EVO injection. Particularly, several keystone sulfate-reducing bacteria showed strong negative interactions with their network neighbours. These results provide mechanistic understanding of the decreased phylogenetic diversity during environmental perturbations. © 2015 Society for Applied Microbiology and John Wiley & Sons Ltd.

Herbal medicines are perceived to be safe by the general public and medical practitioners, despite abundant evidence from clinical trials and case reports that show herbal preparations can have significant adverse effects. The overall impact of adverse events to herbal medicines in Australia is currently unknown. Post marketing surveillance of medications through spontaneous adverse drug reaction (ADR) reports to the Therapeutic Goods Administration (TGA) is one way to estimate this risk. The patterns of spontaneously reported ADRs provide insight to herbal dangers, especially when compared with patterns of a mechanistically similar conventional drug. The study compared the pattern of spontaneously reported ADRs to St. John's Wort (Hypericum perforatum), a common herbal treatment for depression which contains selective serotonin reuptake inhibitors (SSRI), to fluoxetine, a commonly prescribed synthetic SSRI antidepressant. Spontaneous ADR reports sent to the TGA between 2000-2013 for St. John's Wort (n = 84) and fluoxetine (n = 447) were obtained and analysed. The demographic information, types of interaction, severity of the ADR, and the body systems affected (using the Anatomical Therapeutic Chemical classification system) were recorded for individual ADR cases. The majority of spontaneously reported ADRs for St. John's Wort and fluoxetine were concerning females aged 26-50 years (28.6%, 22.8%). The organ systems affected by ADRs to St John's Wort and fluoxetine have a similar profile, with the majority of cases affecting the central nervous system (45.2%, 61.7%). This result demonstrates that herbal preparations can result in ADRs similar to those of prescription medications. © 2015 Wiley Publishing Asia Pty Ltd.

The present study investigated the effect of combined exposure of pyridostigmine bromide (PB) and chronic shaker stress on acoustic startle responses (ASR), pre-pulse inhibition (PPI) and open field behavior of adult C57BL/6J mice. PB (10 mg kg(-1) day(-1) for 7 days) or saline was administered subcutaneously using osmotic Alzet minipumps implanted under the skin on the back of the mice. At the same time, the mice were exposed to 7 days of intermittent shaker stress. They were tested for ASR (100 dB and 120 dB stimuli) and PPI (70 dB + 100 dB and 70 dB + 120 dB) in the acoustic startle monitor system. The mice were assessed during the shaker stress on days 2 and 7 and 7, 14, 21 and 28 days after discontinuation of treatment. Separate groups of mice were tested in the open field in 15 min sessions on days 1, 3 and 6 during shaker stress and PB treatment. Exposure of mice to PB resulted in an exaggerated ASR, reduced PPI and non-significant decrease in locomotor activity. These behavioral changes were apparent only during exposure to PB. Repeated shaker stress did not have any effect on sensorimotor functions or open field behavior of mice. There was no prolonged or delayed effect of PB and/or stress on individual behavioral variables. The study found C57BL/6J mice to be behaviorally sensitive to PB treatment.

Many plants sense the seasonal cues, day length or photoperiod changes, to align the timing of the developmental transition to flowering with changing seasons for reproductive success. Inductive day lengths through the photoperiod pathway induce the expression of FLOWERING LOCUS T (FT) or FT relatives that encode a major mobile florigen to promote flowering. In Arabidopsis thaliana, under inductive long days the photoperiod pathway output CONSTANS (CO) accumulates toward the end of the day, and associates with the B and C subunits of Nuclear Factor Y (NF-Y) to form the NF-CO complex that acts to promote FT expression near dusk, whereas Polycomb group (PcG) proteins function to silence FT expression. How NF-CO acts to antagonize the function of PcG proteins to regulate FT expression remains unclear. Here, we show that the NF-CO complex bound to the proximal FT promoter, through chromatin looping, acts in concert with an NF-Y complex bound to a distal enhancer to reduce the levels of PcG proteins, including both Polycomb repressive complex 1 (PRC1) and PRC2 at the FT promoter, leading to a relieving of Polycomb silencing and thus FT de-repression near dusk. Thus, our study provides molecular insights on how the 'active' photoperiod pathway and the 'repressive' Polycomb silencing system interact to control temporal FT expression, conferring the long-day induction of flowering in Arabidopsis. © 2018 The Authors The Plant Journal © 2018 John Wiley & Sons Ltd.

Dr. John J. 'Jack' Downes (1930-), the anesthesiologist-in-chief at The Children's Hospital of Philadelphia (1972-1996), has made numerous contributions to pediatric anesthesia and critical care medicine through a broad spectrum of research on chronic respiratory failure, status asthmaticus, postoperative risks of apnea in premature infants, and home-assisted mechanical ventilation. However, his defining moment was in January 1967, when The Children's Hospital of Philadelphia inaugurated its pediatric intensive care unit--the first of its kind in North America. During his tenure, he and his colleagues trained an entire generation of pediatric anesthesiologists and intensivists and set a standard of care and professionalism that continues to the present day. Based on an interview with Dr. Downes, this article reviews a career that advanced pediatric anesthesia and critical care medicine and describes the development of that first pediatric intensive care unit at The Children's Hospital of Philadelphia. © 2013 John Wiley & Sons Ltd.

The Reverend William Bell had six children who survived infancy. Two of his sons entered the legal profession and two other sons became distinguished anatomists and surgeons--John Bell, said for 20 years to have been the leading operating surgeon in Britain and throughout the world--and Sir Charles Bell, possibly the most distinguished anatomist and physiologist of his day. Information is not known about the fifth son or their sister. Charles Shaw, a lawyer of Ayr, had four sons and two daughters who survived infancy. Two of his sons, John and Alexander, became anatomists and later surgeons at the Middlesex Hospital, and both worked closely with Charles Bell at the Great Windmill Street School of Anatomy. His third son entered the law and his fourth son became a distinguished soldier. The two daughters of Charles Shaw married into the Bell family: Barbara married George Joseph Bell and Marion married Mr (later Sir) Charles Bell.

Few studies have compared water exposure between different occupations in the general population. To investigate and compare the extent of occupational water exposure, with a focus on service, healthcare and production occupations previously classified as involving a high risk for hand eczema. In two public health surveys (2006 and 2010), a validated question regarding occupational water exposure was answered by 18 342 and 15,736 gainfully employed individuals, respectively. Exposure for ≥ 0.5 h/day was reported by 17.5% and 16.3% (p = 0.020) for the respective years, and exposure for > 2 h/day by 7.8% and 7.7% (p = 0.73). Exposure in women was almost twice as high as in men for both years (p ≤ 0.001) and exposure levels (p < 0.001). Exposure for > 2 h/day was more common in high-risk occupations in service and healthcare than in non-high-risk occupations [prevalence proportion ratios of 16.7 (95%CI: 14.0-20.0) and 8.3 (95%CI: 6.9-9.9), respectively]. Exposure was highest in service occupations, where 44.6% reported exposure for > 2 h/day in 2010, and kitchen work, cleaning and hairdressing dominated. In healthcare, the corresponding figure was 22.0%. Challenging differences in water exposure between occupational groups were found, and extensive water exposure was reported in a number of occupations previously classified as involving a high risk for hand eczema. © 2015 John Wiley & Sons A/S.

This study aimed to evaluate the histological changes occurring in rat skin with increasing age, starting from the intrauterine period. Thirty-two healthy female Sprague-Dawley rats were evaluated in four groups: group 1 - intrauterine day 19, group 2 - postpartum day 21, group 3 - postpartum day 60, and group 4 - postpartum month 19. Skin samples from the back, abdomen, head, and upper and lower limbs were obtained from each subject under anesthesia. Tissue specimens were evaluated statistically and morphologically for the thicknesses of the epidermis, dermis, and basement membrane; the number, height, and width of dermal papillae; and the mast cell and pilosebaceous counts per group. The changes in collagen/elastic fibers and glycosaminoglycans were also assessed. Epidermal thickness was the highest in the intrauterine group; it decreased in the postpartum period and increased again in the aged group. Basal membrane thickness increased steadily with age. The number, height, and width of dermal papillae and dermal thickness increased up to day 60 after birth although these decreased in the aged group. Mast cell count also reached the maximum in the intrauterine group and gradually decreased with age. Pilosebaceous units of the dermis were fewer in intrauterine specimens; they showed an increase during the postpartum period and a decrease in the aged group. Skin specimens obtained from rats showed striking differences between the intrauterine and postpartum groups. Moreover, the postpartum group showed considerable intra-group differences. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Heavily pretreated patients with relapsed and refractory multiple myeloma are susceptible to treatment-related adverse events (AEs). Managing AEs are important to ensure patients continue therapy long enough to receive the best clinical benefit. Data from the MM-002, MM-003, and MM-010 trials were pooled to further characterize the safety profile of pomalidomide plus low-dose dexamethasone and AE management. This analysis included 1088 patients who received ≥ 2 prior therapies, including lenalidomide and bortezomib, and progressed ≤ 60 days of last therapy. Patients received 28-day cycles of pomalidomide 4 mg/day on days 1-21 and low-dose dexamethasone 40 mg (20 mg if aged > 75 years) weekly until disease progression or unacceptable toxicity. Thromboprophylaxis was required. The most common grade 3/4 AEs were neutropenia (56.2%), anemia (32.3%), and thrombocytopenia (25.8%), which occurred within the first few cycles of treatment. Grade 3/4 infections occurred in 33.7% patients, of whom 13.9% had pneumonia, and 40.3% had neutropenia. Pomalidomide dose reductions or interruptions were reported in 24.2% and 66.0% of patients, respectively. AEs were managed by dose modifications and/or supportive care. Pomalidomide plus low-dose dexamethasone showed an acceptable safety profile, and AEs were well managed according to study protocols and established guidelines. © 2017 John Wiley & Sons A/S.

Exercising in the heat induces thermoregulatory and other physiological strain that can lead to impairments in endurance exercise capacity. The purpose of this consensus statement is to provide up-to-date recommendations to optimize performance during sporting activities undertaken in hot ambient conditions. The most important intervention one can adopt to reduce physiological strain and optimize performance is to heat acclimatize. Heat acclimatization should comprise repeated exercise-heat exposures over 1-2 weeks. In addition, athletes should initiate competition and training in a euhydrated state and minimize dehydration during exercise. Following the development of commercial cooling systems (e.g., cooling vest), athletes can implement cooling strategies to facilitate heat loss or increase heat storage capacity before training or competing in the heat. Moreover, event organizers should plan for large shaded areas, along with cooling and rehydration facilities, and schedule events in accordance with minimizing the health risks of athletes, especially in mass participation events and during the first hot days of the year. Following the recent examples of the 2008 Olympics and the 2014 FIFA World Cup, sport governing bodies should consider allowing additional (or longer) recovery periods between and during events for hydration and body cooling opportunities when competitions are held in the heat. © 2015 John Wiley & Sons A/S.

A recombinant vaccine composed of a fusion protein formulated with aluminum hydroxide adjuvant is under development for protection against diseases caused by Streptococcus pyogenes. The safety and local reactogenicity of the vaccine was assessed by a comprehensive series of clinical, pathologic and immunologic tests in preclinical experiments. Outbred mice received three intramuscular injections of 1/5th of the human dose (0.1 ml) and rabbits received two injections of the full human dose. Control groups received adjuvant or protein antigen. The vaccine did not cause clinical evidence of systemic toxicity in mice or rabbits. There was a transient increase of peripheral blood neutrophils after the third vaccination of mice. In addition, the concentration of acute phase proteins serum amyloid A and haptoglobin was significantly increased 1 day after injection of the vaccine in mice. There was mild transient swelling and erythema of the injection site in both mice and rabbits. Treatment-related pathology was limited to inflammation at the injection site and accumulation of adjuvant-containing macrophages in the draining lymph nodes. In conclusion, the absence of clinical toxicity in two animal species suggest that the vaccine is safe for use in a phase I human clinical trial. Copyright © 2016 John Wiley & Sons, Ltd.

Lichen planus follicularis tumidus (LPFT) represents an uncommon variety of lichen planus (LP). Clinically, it presents with prominent purplish lesions or white-pigmented yellowish cysts and comedones. Histopathologically, it is similar to lichen planopilaris, and it is additionally characterized by follicles and cysts surrounded by a lichenoid lymphocytic infiltrate. The most common location is the retroauricular region, and it may be associated with other variants of LP. Herein, we describe the case of a 50-year-old woman with a history of lower limb hypertrophic LP who subsequently presented with multiple pink, tumid, pruritic plaques with white-yellow cysts and comedones extensively affecting the bilateral face. Histopathologic examination revealed a lichenoid infiltrate surrounding the follicles and cysts. We diagnosed LPFT and began treatment with topical corticosteroids, antihistamines, systemic corticosteroids and oral acitretin without improvement. Subsequently, the patient had an acceptable response to cyclosporine at doses of 5 mg/kg/day with remission of itching and tumidity but with residual cysts and comedones remaining. To date, the literature contains only 16 cases of LPFT. To our knowledge, this is the most severe case and is the only one with cessation of disease activity in response to cyclosporine. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

A group of National Advisory Committee for Aeronautics (NACA) officials and local dignitaries were on hand on May 8, 1942, to witness the Initiation of Research at the NACA's new Aircraft Engine Research Laboratory in Cleveland, Ohio. The group in this photograph was in the control room of the laboratory's first test facility, the Engine Propeller Research Building. The NACA press release that day noted, "First actual research activities in what is to be the largest aircraft engine research laboratory in the world was begun today at the National Advisory Committee for Aeronautics laboratory at the Cleveland Municipal Airport.” The ceremony, however, was largely symbolic since most of the laboratory was still under construction. Dr. George W. Lewis, the NACA's Director of Aeronautical Research, and John F. Victory, NACA Secretary, are at the controls in this photograph. Airport Manager John Berry, former City Manager William Hopkins, NACA Assistant Secretary Ed Chamberlain, Langley Engineer-in-Charge Henry Reid, Executive Engineer Carlton Kemper, and Construction Manager Raymond Sharp are also present. The propeller building contained two torque stands to test complete engines at ambient conditions. The facility was primarily used at the time to study engine lubrication and cooling systems for World War II aircraft, which were required to perform at higher altitudes and longer ranges than previous generations.

Eighty-eight dogs with relapsed lymphoma were treated with the MOMP (mechlorethamine, vincristine, melphalan and prednisone) protocol on a 28-day treatment cycle. The overall response rate (ORR) to the MOMP protocol was 51.1% for a median of 56 days (range 7-858 days). Twelve percent of dogs experienced a complete response for a median of 81 days (range 42-274 days) and 38.6% experienced a partial response for a median of 49 days (range 7-858 days). Dogs with T-cell lymphoma had an ORR of 55% for a median of 60 days (range 49-858 days) while those with B-cell lymphoma had an ORR of 57% for a median of 81 days (range 7-274 days) (P = 0.783). The overall survival time for all dogs was 183 days (range 17-974 days). Fifty-four percent of dogs experienced toxicity with the majority classified as grade I. The MOMP protocol seems well-tolerated and is an option for dogs with relapsed lymphoma. © 2013 John Wiley & Sons Ltd.

Day-night variation in heart rate variability changes induced by endotoxaemia in healthy volunteers.

Morbidity and mortality in response to sepsis may be dependent on clock time for the initiation of sepsis. Endotoxaemia, an experimental model for systemic inflammation, induces alterations in sympatico-vagal balance in the autonomic nervous system (ANS). The activity of sympathetic and parasympathetic activity can be estimated by measuring heart rate variability (HRV). Based on the intimate link between ANS and the inflammatory response, we hypothesized, that HRV changes seen during endotoxaemia would be different based on time of the day the endotoxaemia is initiated. We investigated day/night variation in endotoxaemia-induced changes in HRV. A randomized, crossover study with 12 healthy men (age 18-31) was conducted. Endotoxaemia were induced by lipopolysaccharide (LPS) endotoxin 0.3 ng/kg b.w. in two visits (day visit and night visit). At the day visit, endotoxaemia were induced at 12:00 h, and at the night visit it was induced at 24:00 h. Holter recordings were started 1 h before administration of LPS, and continued for 10 h. Time-domain and frequency-domain parameters of HRV were analysed. A total of nine persons finished the study with valid recordings. Endotoxaemia at both night and day resulted in a significant depression in HRV parameters high-frequency power (HF), low-frequency power (LF), standard deviation of normal-to-normal (NN) intervals, root mean square of successive differences and proportion of NN50 divided by total number of NNs (P<0.001). The ratio LF/HF and mean heart rate significantly increased by endotoxaemia (P<0.001). At night-time endotoxaemia, a more pronounced depression of LF, HF and SDNN (P<0.01) and a more pronounced increase in the ratio of LF/HF and mean heart rate (P<0.01) occurred compared with day-time endotoxaemia. Endotoxaemia induced changes in HRV exhibit a day-night difference. This difference may have clinical consequences in patients with sepsis. © 2015 The Acta Anaesthesiologica Scandinavica Foundation.

Mycobacterium avium ssp. paratuberculosis (MAP) is the cause of Johne's disease, an inflammatory bowel disorder of ruminants. Due to the similar pathology, MAP was also suggested to cause Crohn's disease (CD). Despite of intensive research, this question is still not settled, possibly due to the lack of versatile mouse models. The aim of this study was to identify basic immunologic mechanisms in response to MAP infection. Immune compromised C57BL/6 Rag2-/- mice were infected with MAP intraperitoneally. Such chronically infected mice were then reconstituted with CD4+ and CD8+ T cells 28 days after infection. A systemic inflammatory response, detected as enlargement of the spleen and granuloma formation in the liver, was observed in mice infected and reconstituted with CD4+ T cells. Whereby inflammation in infected and CD4+CD45RB(hi) T cell reconstituted animals was always higher than in the other groups. Reconstitution of infected animals with CD8+ T cells did not result in any inflammatory signs. Interestingly, various markers of inflammation were strongly up-regulated in the colon of infected mice reconstituted with CD4+CD45RB(lo/int) T cells. We propose, the usual non-colitogenic CD4+CD45RB(lo/int) T cells were converted into inflammatory T cells by the interaction with MAP. However, the power of such cells might be not sufficient for a fully established inflammatory response in the colon. Nevertheless, our model system appears to mirror aspects of an inflammatory bowel disease (IBD) like CD and Johne's diseases. Thus, it will provide an experimental platform on which further knowledge on IBD and the involvement of MAP in the induction of CD could be acquired.

Both high and low indoor relative humidity (RH) directly impact Indoor Air Quality (IAQ), an important school health concern. Prior school studies reported a high prevalence of mold, roaches, and water damage; however, few examined associations between modifiable classroom factors and RH, a quantitative indicator of dampness. We recorded RH longitudinally in 134 North Carolina classrooms (n = 9066 classroom-days) to quantify the relationships between modifiable classroom factors and average daily RH below, within, or above levels recommended to improve school IAQ (30-50% or 30-60% RH). The odds of having high RH (>60%) were 5.8 [95% Confidence Interval (CI): 2.9, 11.3] times higher in classrooms with annual compared to quarterly heating, ventilating, and air-conditioning (HVAC) system maintenance and 2.5 (95% CI: 1.5, 4.2) times higher in classrooms with HVAC economizers compared to those without economizers. Classrooms with direct-expansion split systems compared to chilled water systems had 2.7 (95% CI: 1.7, 4.4) times higher odds of low RH (<30%). When unoccupied, classrooms with thermostat setbacks had 3.7 (95% CI: 1.7, 8.3) times the odds of high RH (>60%) of those without setbacks. This research suggests actionable decision points for school design and maintenance to prevent high or low classroom RH. This study combines longitudinal measurements of classroom relative humidity with school inspection data from several schools to describe the problem of relative humidity control in schools. Our findings on how maintenance and mechanical factors affect classroom humidity provide suggestions on building operations policies and heating, ventilating, and air-conditioning (HVAC) design considerations that may improve classroom relative humidity control. © 2014 John Wiley & Sons A/S.

The effects of Alpinia protocatechuic acid (PCA) on spleen and liver antioxidant system in aged rats have been studied. Alpinia PCA, a phenolic compound, was first isolated from the dried fruits of Alpinia Oxyphylla Miq. in our laboratory. Young and aged rats were injected intraperitoneally with Alpinia PCA at single doses of 5 mg kg(-1) (low dose) or 10 mg kg(-1) (high dose) per day for 7 days. The activities of endogenous antioxidants and the content of lipid peroxide in spleen and liver were assayed. Compared with young group, aged rats had significantly lower splenic weights, lower activities of glutathione peroxidase (GSH-PX) and catalase (CAT), higher level of malondialdehyde (MDA) in spleen and liver. The results proved that Alpinia PCA significantly elevated the splenic weights, increased the activities of GSH-PX and CAT and decreased the MDA level of aged rats. All these suggested that Alpinia PCA was a potential anti-ageing agent, and its effects on spleen and liver were achieved at least partly by promoting endogenous antioxidant enzymatic activities and normalizing age-associated alterations. It may be therapeutically useful to minimize age-associated disorders where oxidative damage is the major cause. Copyright © 2011 John Wiley & Sons, Ltd.

Current methods of sports injury surveillance are limited by lack of medical validation of self-reported injuries and/or incomplete information about injury consequences beyond time loss from sport. The aims of this study were to (a) evaluate the feasibility of the SMS, Phone, and medical Examination injury surveillance (SPEx) system (b) to evaluate the proportion of injuries and injury consequences reported by SPEx when compared to outcomes from a modified version of the Oslo Sports Trauma Research Centre (OSTRC) Overuse Injury Questionnaire. We followed 679 elite adolescent handball players over 31 weeks using the SPEx system. During the last 7 weeks, we also implemented a modified OSTRC questionnaire in a subgroup of 271 players via telephone interviews. The weekly response proportions to the primary SPEx questions ranged from 85% to 96% (mean 92%). SMS responses were received from 79% of the participants within 1 day. 95% of reported injuries were classified through the telephone interview within a week, and 67% were diagnosed by medical personnel. Comparisons between reported injuries from SPEx and OSTRC demonstrated fair (κ = 39.5% [25.1%-54.0%]) to substantial prevalence-adjusted bias-adjusted kappa (PABAK = 66.8% [95% CI 58.0%-75.6%]) agreement. The average injury severity score difference between SPEx and the OSTRC approach was -0.2 (95% CI -3.69-3.29) of possible 100 with 95% limits of agreement from(-14.81-14.41). These results support the feasibility and validity of the SPEx injury surveillance system in elite youth sport. Future studies should evaluate the external validity of SPEx system in different cohorts of athletes. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Under the environment of pregnancy, the placenta assumes an important steroidogenic role in the maintenance of pregnancy. Urinary placental leucine aminopeptidase (PLAP), estrone-3-glucuronide (E 1 G), and pregnanediol-3-glucuronide (PdG) concentrations were compared among five pregnancies (four live births and one stillbirth) in four orangutans. The gestation period of the stillbirth (223 days) was shorter than that of the live births (239-254 days). In females who gave a live birth, average PLAP and E 1 G concentrations increased until the delivery. Conversely, in the female who gave a stillbirth, PLAP concentration failed to increase, and E 1 G concentration was significantly low in late pregnancy period. Regarding PdG concentrations, there was no significant difference among all pregnancies. This is the first study reporting a change in urinary PLAP, E 1 G, and PdG concentrations during orangutan stillbirth and live birth pregnancies. The findings will assist in developing pregnancy screening tests. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Antoine, Alan D. (Johns Hopkins University-Leonard Wood Memorial Leprosy Research Laboratory, Baltimore, Md.), Norman E. Morrison, and John H. Hanks. Specificity of improved methods for mycobactin bioassay by Arthrobacter terregens. J. Bacteriol. 88:1672–1677. 1964.—Arthrobacter terregens was used to assay mycobactin, a growth factor for Mycobacterium paratuberculosis. Improved techniques permit the assay of mycobactin within 3 to 4 days by agarplate or liquid-medium methods. For the agarplate method, Arthrobacter terregens gave linear increases in zonal growth at mycobactin concentrations of 0.07 to 0.30 μg per spot; for the liquid-medium method, linear increases in turbidimetric growth occurred at 0.05 to 0.27 μg/ml. Specificity studies show that the mycobactin hydrolytic products, cobactin and mycobactic acid, function as growth stimulators, but the high concentrations required would produce only minimal interference in mycobactin assays. Furthermore, the response to mycobactic acid is characterized by a delayed response of 3 days. Various synthetic hydroxylamine-containing compounds and metalchelating agents cannot replace the biological activity of mycobactin. Diacetylmycobactin is 7.4 times more effective than mycobactin as a growth stimulator. PMID:14240956

To evaluate the clinical efficacy, and safety of newly customized natural oral mucoadhesive gels, containing either aloe vera or myrrh as active ingredients, in the management of minor recurrent aphthous stomatitis (MiRAS). Ninety subjects with MiRAS were recruited from Oral Medicine Clinic, at Faculty of Dentistry, King Abdulaziz University, Saudi Arabia, for this randomized, double-blind, placebo-controlled study. Two new natural gels, containing aloe vera and myrrh, were prepared in a concentration of (0.5% w/w), in addition to a plain mucoadhesive gel used as a placebo. Patients with fresh ulcers (<48-h duration) were instructed to apply either one of the three gels four times a day for a period of 5 days. Clinical efficacy was investigated in the form of changes in ulcer size, pain intensity, erythema, and exudation at days 4 and 6 of study entry. Participants were interviewed for the emergence of any side effects. 76.6% of patients using aloe gel showed complete ulcer healing, 86.7%, and 80% of them revealed subsidence of erythema and exudation, respectively, especially at day 6 visit, whereas 76.7% of myrrh-treated patients revealed almost absence of pain at day 6. No side effects were encountered with the use of any of the three gels. The new formulated aloe- and myrrh-based gels proved to be effective in topical management of MiRAS. Aloe was superior in decreasing ulcer size, erythema, and exudation; whereas myrrh resulted in more pain reduction. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

There are controversial data about the effects of sun exposure on atopic dermatitis (AD). We evaluated the association between solar ultraviolet radiation (UVR) exposure and AD symptoms in children. Eighty-two children under 6 years (48 boys and 34 girls) with AD living in Seoul, Korea, were enrolled and followed for 12 months between September 2013 and August 2014. Daily symptoms were recorded to describe the degree of itching, sleep disturbance, erythema, dryness, oozing, and edema. We assessed solar UVR by measuring radiation heat flux over the 290-400 nm wavelength range using thermopiles. A generalized linear mixed model and a generalized additive mixed model were used to evaluate the effects of UVR exposure on AD symptoms after adjusting for age, sex, outdoor temperature, outdoor humidity, and ambient air pollution. Symptom records of 12 915 person-days were analyzed. UVR showed a significantly positive relationship with AD symptoms. Over the study period, an increase in UVR by 10 W/cm 2 was associated with a 1.46% increase in AD symptoms (95% CI: 0.85-2.07) on the exposure day. An increase in the 6-day average level of UVR of the previous 5 days and the current day by 10 W/cm 2 was associated with a 3.58% (95% CI: 2.60-4.56) increase in AD symptoms. UVR exposure significantly increased AD symptoms in autumn, but decreased them in winter. Atopic dermatitis symptoms in children are likely to be affected by exposure to solar UVR with a cumulative effect, and this effect is different according to season. © 2017 EAACI and John Wiley and Sons A/S.

Multimorbidity in allergic airway diseases is well known, but no data exist about the daily dynamics of symptoms and their impact on work. To better understand this, we aimed to assess the presence and control of daily allergic multimorbidity (asthma, conjunctivitis, rhinitis) and its impact on work productivity using a mobile technology, the Allergy Diary. We undertook a 1-year prospective observational study in which 4 210 users and 32 585 days were monitored in 19 countries. Five visual analogue scales (VAS) assessed the daily burden of the disease (i.e., global evaluation, nose, eyes, asthma and work). Visual analogue scale levels <20/100 were categorized as "Low" burden and VAS levels ≥50/100 as "High" burden. Visual analogue scales global measured levels assessing the global control of the allergic disease were significantly associated with allergic multimorbidity. Eight hypothesis-driven patterns were defined based on "Low" and "High" VAS levels. There were <0.2% days of Rhinitis Low and Asthma High or Conjunctivitis High patterns. There were 5.9% days with a Rhinitis High-Asthma Low pattern. There were 1.7% days with a Rhinitis High-Asthma High-Conjunctivitis Low pattern. A novel Rhinitis High-Asthma High-Conjunctivitis High pattern was identified in 2.9% days and had the greatest impact on uncontrolled VAS global measured and impaired work productivity. Work productivity was significantly correlated with VAS global measured levels. In a novel approach examining daily symptoms with mobile technology, we found considerable intra-individual variability of allergic multimorbidity including a previously unrecognized extreme pattern of uncontrolled multimorbidity. © 2018 EAACI and John Wiley and Sons A/S.

The idea of acute-on-chronic liver failure (ACLF) has emerged to identify those subjects with organ failure and high mortality rates. However, the absence of a precise definition has limited the clinical application and research related to the ACLF concept. We sought to validate the ACLF definition and the CLIF-SOFA Score recently proposed by the EASL-CLIF Consortium in a cohort of patients admitted for acute decompensation (AD) of cirrhosis. In this prospective cohort study, patients were followed during their hospital stay and thirty and 90-day mortality was evaluated by phone call, in case of hospital discharge. All subjects underwent laboratory evaluation at admission. Between December 2010 and November 2013, 192 cirrhotic patients were included. At enrollment, 46 patients (24%) met the criteria for ACLF (Grades 1, 2 and 3 in 18%, 4% and 2% respectively). The 30-day mortality was 65% in ACLF group and 12% in the remaining subjects (P < 0.001). Logistic regression analysis showed that 30-day mortality was independently associated with ascites and ACLF at admission. The Kaplan-Meier survival probability at 90-day was 92% in patients without ascites or ACLF and only 22% for patients with both ascites and ACLF. The AUROC of CLIF-SOFA in predicting 30-day mortality was 0.847 ± 0.034, with sensitivity of 64%, specificity of 90% and positive likelihood ratio of 6.61 for values ≥9. In our single-centre experience the CLIF-SOFA and the EASL-CLIF Consortium definition of ACLF proved to be strong predictors of short-term mortality in cirrhotic patients admitted for AD. © 2014 John Wiley & Sons A/S.

To evaluate the cardiac safety of adjunctive lacosamide in a large pool of adults with partial-onset seizures (POS). Post-randomization changes from baseline for electrocardiographic (ECG) measurements, diagnostic findings, and relevant adverse events (AEs) were compared for pooled data from three randomized, placebo-controlled trials of adjunctive lacosamide for the treatment of POS. Lacosamide did not prolong the QTc interval or affect heart rate as determined by an analysis of data from patients randomized to lacosamide 200, 400, or 600 mg/day (n = 944) compared with placebo (n = 364). After 12-week maintenance treatment, mean changes from baseline for QRS duration were similar between the placebo and lacosamide 200 and 400 mg/day groups (0.0, -0.2, and 0.4 ms), but slightly increased for lacosamide 600 mg/day (2.3 ms). A small, dose-related mean increase in PR interval was observed (-0.3, 1.4, 4.4, and 6.6 ms for the placebo and lacosamide 200, 400, and 600 mg/day groups, respectively). First-degree atrioventricular (AV) block was reported as a non-serious AE in 0.0%, 0.7%, 0.2%, and 0.5% of patients in the same respective groups. Second- or higher degree AV block was not observed. There was no evidence of a PR-interval-related pharmacodynamic interaction of lacosamide with either carbamazepine or lamotrigine. Evaluation of the pooled cardiac safety data from patients with POS showed that adjunctive lacosamide at the maximum recommended dose (400 mg/day) was not clearly associated with any cardiac effect other than a small, dose-related increase in PR interval that had no evident symptomatic consequence. © 2015 John Wiley & Sons A/S.

St. John's wort attenuates irinotecan-induced diarrhea via down-regulation of intestinal pro-inflammatory cytokines and inhibition of intestinal epithelial apoptosis

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hu Zeping; Yang Xiaoxia; Chan Suiyung

Diarrhea is a common dose-limiting toxicity associated with cancer chemotherapy, in particular for drugs such as irinotecan (CPT-11), 5-fluouracil, oxaliplatin, capecitabine and raltitrexed. St. John's wort (Hypericum perforatum, SJW) has anti-inflammatory activity, and our preliminary study in the rat and a pilot study in cancer patients found that treatment of SJW alleviated irinotecan-induced diarrhea. In the present study, we investigated whether SJW modulated various pro-inflammatory cytokines including interleukins (IL-1{beta}, IL-2, IL-6), interferon (IFN-{gamma}) and tumor necrosis factor-{alpha} (TNF-{alpha}) and intestinal epithelium apoptosis in rats. The rats were treated with irinotecan at 60 mg/kg for 4 days in combination with oralmore » SJW or SJW-free control vehicle at 400 mg/kg for 8 days. Diarrhea, tissue damage, body weight loss, various cytokines including IL-1{beta}, IL-2, IL-6, IFN-{gamma} and TNF-{alpha} and intestinal epithelial apoptosis were monitored over 11 days. Our studies demonstrated that combined SJW markedly reduced CPT-11-induced diarrhea and intestinal lesions. The production of pro-inflammatory cytokines such as IL-1{beta}, IFN-{gamma} and TNF-{alpha} was significantly up-regulated in intestine. In the mean time, combined SJW significantly suppressed the intestinal epithelial apoptosis induced by CPT-11 over days 5-11. In particular, combination of SJW significantly inhibited the expression of TNF-{alpha} mRNA in the intestine over days 5-11. In conclusion, inhibition of pro-inflammatory cytokines and intestinal epithelium apoptosis partly explained the protective effect of SJW against the intestinal toxicities induced by irinotecan. Further studies are warranted to explore the potential for STW as an agent in combination with chemotherapeutic drugs to lower their dose-limiting toxicities.« less

Productivity of Spring Chinook Salmon and Summer Steelhead in the John Day River Basin, 2008 Annual Technical Report.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wilson, Wayne H.; Schricker, Jaym'e; Ruzychi, James R.

The John Day River subbasin supports one of the last remaining intact wild populations of spring Chinook salmon and summer steelhead in the Columbia River Basin. These populations remain depressed relative to historic levels and limited information is available for steelhead life history. Numerous habitat protection and rehabilitation projects have been implemented in the basin to improve salmonid freshwater production and survival. However, these projects often lack effectiveness monitoring. While our monitoring efforts outlined here will not specifically measure the effectiveness of any particular project, they will provide much needed programmatic or watershed (status and trend) information to help evaluatemore » project-specific effectiveness monitoring efforts as well as meet some data needs as index stocks. Our continued monitoring efforts to estimate salmonid smolt abundance, age structure, SAR, smolts/redd, freshwater habitat use, and distribution of critical life states will enable managers to assess the long-term effectiveness of habitat projects and to differentiate freshwater and ocean survival. Because Columbia Basin managers have identified the John Day subbasin spring Chinook population as an index population for assessing the effects of alternative future management actions on salmon stocks in the Columbia Basin (Schaller et al. 1999) we continue our ongoing studies. This project is high priority based on the level of emphasis by the NWPPC Fish and Wildlife Program, Independent Scientific Advisory Board (ISAB), Independent Scientific Review Panel (ISRP), NOAA National Marine Fisheries Service (NMFS), and the Oregon Plan for Salmon and Watersheds (OWEB). Each of these groups have placed priority on monitoring and evaluation to provide the real-time data to guide restoration and adaptive management in the region. The objective is to estimate smolt-to-adult survival rates (SAR) and out-migrant abundance for spring Chinook Oncorhynchus tshawytscha and summer steelhead O. mykiss and life history characteristics of summer steelhead.« less

The effects of juvenile American shad planktivory on zooplankton production in Columbia River food webs

Haskell, Craig A.; Tiffan, Kenneth F.; Rondorf, Dennis W.

2013-01-01

Columbia River reservoirs support a large population of nonnative American Shad Alosa sapidissima that consume the zooplankton that native fishes also rely on. We hypothesized that the unprecedented biomass of juvenile American Shad in John Day Reservoir is capable of altering the zooplankton community if these fish consume a large portion of the zooplankton production. We derived taxon-specific estimates of zooplankton production using field data and a production model from the literature. Empirical daily ration was estimated for American Shad and expanded to population-level consumption using abundance and biomass data from hydroacoustic surveys. Daphnia spp. production was high in early summer but declined to near zero by September as shad abundance increased. American Shad sequentially consumed Daphnia spp., copepods, and Bosmina spp., which tracked the production trends of these taxa. American Shad evacuation rates ranged from 0.09 to 0.24/h, and daily rations ranged from 0.008 to 0.045 g·g−1·d−1 (dry weight) over all years. We observed peak American Shad biomass (45.2 kg/ha) in 1994, and daily consumption (1.6 kg/ha) approached 30% (5.3 kg/ha) of zooplankton production. On average, American Shad consumed 23.6% of the available zooplankton production (range, <1–83%). The changes in the zooplankton community are consistent with a top-down effect of planktivory by American Shad associated with their unprecedented biomass and consumption, but the effects are likely constrained by temperature, nutrient flux, and the seasonal production patterns of zooplankton in John Day Reservoir. American Shad add to the planktivory exerted by other species like Neomysis mercedis to reduce the capacity of the reservoir to support other planktivorous fishes. The introduction of American Shad and other nonnative species will continue to alter the food web in John Day Reservoir, potentially affecting native fishes, including Pacific salmon Oncorhynchus spp.

This study reports on the full-day workshop "The Shape of The Future of Dental Education for Dental Caries-and how we get there" held immediately prior to the May 2017 ADEE/ADEA/King's College London meeting "Shaping the Future of Dental Education." A standardised, evidence-led Core Curriculum in Cariology (CCC) was developed jointly and systematically by ORCA and ADEE, starting in 2010. At the same time, the ICDAS Foundation was developing a comprehensive caries management system, ICCMS™. The workshop reported on what has been achieved on a global basis by many building on these initiatives. The CCC has been, or is currently being, localised in a number of places around the world and has, in some countries, been successfully implemented. There are also other areas which are struggling more with the logistics of introducing it. The workshop presented geographical perspectives and experiences on implementing the CCC from Colombia, the United States and Europe, as well as professional perspectives from hygienists, students and policymakers. The workshop then considered the future of the CCC and the roles of Interprofessional Education, Technology, Global Networking and Assessment in a Global Context in 4 breakout groups. Having had reports back and plenary discussion, it was concluded that the caries world has made good progress towards a "futuristic" curriculum with parallel development of a comprehensive, preventive and tooth-preserving caries management system-ICCMS™. The implementation challenge is now to share even more effectively in order to have these developments more widely accepted and adopted worldwide. © 2018 John Wiley & Sons A/S.

Detection and quality of previously undetermined Floridan aquifer system discharge to the St. Johns River, Jacksonville, to Green Cove Springs, northeastern Florida

USGS Publications Warehouse

Spechler, R.M.

1996-01-01

Potentiometric surface maps of the Upper Floridan aquifer show two depressions around the St. Johns River frm the city of Jacksonville south toward Green Cove Springs. These depressions, depending on their locations, are the result of withdrawals from agricultural, industrial, domestic and public-supply wells, diffuse upward leakage, and discharge from springs. Submerged springs that discharge into the St. Johns River between Jacksonville and Green Cove Springs have been thought to exist, but locating and evaluating these springs had not been attempted before this investigation. Thermal infrared imagery, seismic reflection, and numerous interviews with local residents were used to locate springs. An airborne thermal infrared survey was conducted along a section of the St. Johns River in northeastern Florida during February 1992 to detect possible sources of ground-water discharge to the river. An infrared image displayed one thermal anomaly in the St. Johns River which is associated with a previously unknown spring discharge from the Floridan aquifer system. Thermal anomalies also were observed at six locations where municipal facilities discharge treated wastewater to the river. Results of seismic reflection surveys indicate the presence of collapse and other karst features underlying the St. Johns River. These features indicate that the surficial deposits and the Hawthorn Formation that underlie the river probably do not consist of continuous beds. The collapse or deformation of the Hawthorn Formation or the presence of permeable sediment of localized extent could create zones of relatively high vertical leakance. This could provide a more direct hydraulic connection between the Upper Floridan aquifer and the river. Water samples collected from the only submerged spring in the St. Johns River within the Jacksonville-Green Cove Springs reach indicate that the source of the water is the Floridan aquifer system. Chloride and sulfate concentrations were 12 and 340 milligrams per liter, respectively. Specific conductance was 826 microsiemens per centimeter and the temperature of the water discharging from the spring was 25.1 degrees Celsius. The ratio of 87 Strontium/86 Strontium also indicates that the springwater has been in contact with rock materials of Eocene age, providing additional evidence that the springwater is derived from the Floridan aquifer system.

The Internet is used worldwide, but its effect on hospital selection of minor surgical disease has not hitherto been thoroughly studied. To investigate the effect of the Internet dissemination on hospital selection of minor surgical disease and information affecting selection, we conducted a survey of patients who underwent laparoscopic surgery from January 2016 to April 2017. We analyzed the questionnaire responses of 1916 patients. Over 80% of patients in all groups selected the hospital based on Internet information. Among patients aged over 60 years, 65.1% selected the hospital based on Internet information. With regard to hospital selection factors, the highest number of responses was for sophisticated surgical treatment (93.1%). The second highest was for a simplified medical care system (33.0%); third was a comprehensive nursing care system (18.1%). Among responses about surgical treatment, the most were obtained for short operation time and fewer hospitalization days (81.5%). Copyright © 2018 John Wiley & Sons, Ltd.

STS079-S-092 (16-26 Sept. 1996) --- Astronauts Shannon W. Lucid and John E. Blaha work at a microgravity glove box on the Priroda Module aboard Russia's Mir Space Station complex. Blaha, who flew into Earth-orbit with the STS-79 crew, and Lucid are the first participants in a series of ongoing exchanges of NASA astronauts serving time as cosmonaut guest researchers onboard Mir. Lucid went on to spend a total of 188 days in space before returning to Earth with the STS-79 crew. During the STS-79 mission, the crew used an IMAX camera to document activities aboard the Space Shuttle Atlantis and the various Mir modules, with the cooperation of the Russian Space Agency (RSA). A hand-held version of the 65mm camera system accompanied the STS-79 crew into space in Atlantis' crew cabin. NASA has flown IMAX camera systems on many Shuttle missions, including a special cargo bay camera's coverage of other recent Shuttle-Mir rendezvous and/or docking missions.

To determine the effect of perinatal exposure to low doses of genistein and/or vinclozolin on submandibular salivary gland (SSG) development in juvenile and adult male rats and to establish a link with sweet preference. Female rats received orally (1 mg kg(-1) body weight/day) genistein and vinclozolin, alone or in combination, from the first gestational day up to weaning. Sweet preference was assessed at weaning and in adulthood in male offspring; submandibular glands were then collected to study the morphogenesis and mRNA expression of steroid receptors, growth factors and taste related proteins. Exposure to genistein and/or vinclozolin resulted in a higher saccharin intake on postnatal day 25 (P < 0.05) linked to a higher number of pro-acinar cells (P < 0.01) and mRNA expression of progesterone receptor, growth factors and gustine (P < 0.01). These increases disappeared in adulthood, but mRNA expressions of sex hormone receptors and growth factors were strongly repressed in all treated groups (P < 0.01). Our findings confirm that the SSG are target for xenohormones and provide evidence that perinatal exposure to low doses of genistein and/or vinclozolin could simultaneously disrupt not only the salivary gland prepubertal development and sweet intake but also endocrine gene mRNA expression later in life. © 2013 John Wiley & Sons A/S.

BKV-HC is a serious complication of allogeneic HSCT. To characterize the incidence, risk factors, and clinical outcomes of post-HSCT BKV-HC, we retrospectively analyzed 112 patients who underwent one or more allogeneic HSCTs at our hospital between 2001 and 2017. Twenty underwent second or third HSCT thereafter. Ten patients developed BKV-HC at a median of 30 days after HSCT. The 100-day cumulative incidences of grade 0-4 and grade 2-4 BKV-HC were 7.8% and 6.2%, respectively. HSCTs performed in 2011-2017 associated with significantly higher 100-day cumulative incidence of grade 2-4 BKV-HC (14.0%) than HSCTs performed in 2001-2010 (1.3%, P = 0.004). On multivariate analysis, second or third HSCT was the only independent significant risk factor for development of grade 2-4 BKV-HC (P = 0.015). Serial PCR monitoring of urine and blood BKV load did not predict BKV-HC. The recent increase in the incidence of BKV-HC may reflect recent innovations in transplant technologies that facilitate second or third HSCT, which are known to cause prolonged immune deficiency. If safe and effective treatment or prophylaxis becomes available, it could be used to target the high-risk patients for BKV-HC. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Hypertension is associated with platelet alterations that could contribute to the development of cardiovascular complications. Several studies have reported antiplatelet aggregation properties of ginger (Zingiber officinale) and turmeric (Curcuma longa) with limited scientific basis. Hence, this study assessed the effect of dietary supplementation of these rhizomes on platelet ectonucleotidase and adenosine deaminase (ADA) activities in Nω-nitro-l-arginine methyl ester hydrochloride (l-NAME) induced hypertensive rats. Animals were divided into seven groups (n = 10): normotensive control rats; induced (l-NAME hypertensive) rats; hypertensive rats treated with atenolol (10 mg/kg/day); normotensive and hypertensive rats treated with 4% supplementation of turmeric or ginger, respectively. After 14 days of pre-treatment, the animals were induced with hypertension by oral administration of l-NAME (40 mg/kg/day). The results revealed a significant (p < 0.05) increase in platelet ADA activity and ATP hydrolysis with a concomitant decrease in ADP and AMP hydrolysis of l-NAME hypertensive rats when compared with the control. However, dietary supplementation with turmeric or ginger efficiently prevented these alterations by modulating the hydrolysis of ATP, ADP and AMP with a concomitant decrease in ADA activity. Thus, these activities could suggest some possible mechanism of the rhizomes against hypertension-derived complications associated to platelet hyperactivity. Copyright © 2016 John Wiley & Sons, Ltd.

After bilateral lung and heart-lung transplantation in adults with pulmonary hypertension, hemodynamic and oxygenation deficiencies are life-threatening complications that are increasingly managed with extracorporeal life support (ECLS). The primary aim of this retrospective study was to assess 30-day and 1-year survival rates in patients managed with vs without post-operative venoarterial ECLS in 2008-2013. The secondary endpoints were the occurrence rates of nosocomial infection, bleeding, and acute renal failure. Of the 93 patients with pulmonary hypertension who received heart-lung (n=29) or bilateral lung (n=64) transplants, 28 (30%) required ECLS a median of 0 [0-6] hours after surgery completion and for a median of 3.0 [2.0-8.5] days. Compared to ECLS patients, controls had higher survival at 30 days (95.0% vs 78.5%; P=.02) and 1 year (83% vs 64%; P=.005), fewer nosocomial infections (48% vs 79%; P=.0006), and fewer bleeding events (17% vs 43%; P=.008). The need for renal replacement therapy was not different between groups (11% vs 17%; P=.54). Venoarterial ECLS is effective in treating pulmonary graft dysfunction with hemodynamic failure after heart-lung or bilateral lung. However, ECLS use was associated with higher rates of infection and bleeding. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To explore the effects of menstrual cycle on orthodontic pain following initial archwire engagement. Female participants with regular menstrual cycles were recruited and assigned into follicular group or luteal group. Demographical and baseline variables were collected: age, education, menstrual duration, anxiety, oral health impact profile-14 (OHIP-14), and index of complexity outcome and need (ICON). Following initial archwire engagement, orthodontic pain was determined through visual analogue scale (VAS) on 1st day, 2nd day, and 3rd day. Demographical and baseline variables were compared between the two groups. Two-way repeated-measures anova was used to examine the effects of menstrual phase, time, and their interactions on orthodontic pain. Multivariate linear regression was employed to examine the independent effect of each variable on orthodontic pain. Finally, 37 and 39 were assigned to the follicular and luteal groups, respectively, with balanced demographical and baseline data. Orthodontic pain was significantly affected by menstrual phase and time (both P < 0.001), but there was no interaction (P > 0.05). Moreover, orthodontic pain was independently predicted by menstrual phase, OHIP, education level, and anxiety (all P < 0.05). We suggest that practitioners arrange female patients to receive initial archwire engagement during their follicular phases to relieve orthodontic pain. © 2016 John Wiley & Sons A/S.

The aim of this study was comparing the effect of flapless vs. flap technique of implant placement on inflammation degree of peri-implant soft tissue, through histopathological analysis. The experiment was conducted on five domestic pigs. Nine weeks after tooth extraction, implants were installed. Each animal received six implants in mandible. According to split-mouth design, randomly one side was used for flapless technique using mini-incision, while on the other side, flap was raised. After 7, 14, 21, 28, and 90 days, the experimental animals were sacrificed. Samples for histopathological analyzes were taken from the buccal side of peri-implant mucosa next to the neck of implants, from three levels. The degree of inflammatory response in the peri-implant soft tissue was estimated through ordinal scores from 0 to 3. In the flap group Score 3 indicating high degree of inflammation was present from day 7 to day 21, in contrast to flapless group where Score 3 was not recorded during the entire follow-up. Three months after implantation, there were no signs of inflammation neither around flap nor around flapless implants. Flapless surgical implantation technique using mini-incision decreases peri-implant soft tissue inflammatory reaction compared with flap surgery. © 2014 John Wiley & Sons A/S.

The aim of this study was to investigate the possibility of intravenous sedation as a useful pain-relieving option for impacted third molar extractions. A prospective cohort study was conducted among patients who underwent bilateral mandibular third molar extractions under local anaesthesia and intravenous sedation (sedation group) and patients who underwent unilateral mandibular third molar extraction under local anaesthesia alone (local anaesthesia group). The frequency of use of postoperative oral analgesia and the intensity of pain assessed using the full cup test were compared between the two groups. The maximum pain intensity (0-100) on postoperative day 1 in the sedation and local anaesthesia groups was 72.8 ± 16.98 and 84.8 ± 15.84, respectively, and the mean pain intensity was 42.2 ± 16.00 and 49.6 ± 18.94. The maximum and mean pain intensities in the sedation group were significantly milder than those in the local anaesthesia group. The number of oral analgesic doses in the sedation group was significantly smaller on the day of surgery and on postoperative day 1 than in the local anaesthesia group. The results of this study suggest that bilateral impacted mandibular third molar extractions under intravenous sedation could be a recommended treatment option. © 2016 John Wiley & Sons A/S.

Chlamydia trachomatis (CT) is the leading sexually transmitted bacterial infection in humans and is associated with reproductive tract damage. However, little is known about the involvement and regulation of microRNAs (miRs) in genital CT. We analyzed miRs in the genital tract (GT) following C. muridarum (murine strain of CT) challenge of wild type (WT) and CD4(+) T-cell deficient (CD4(-/-)) C57BL/6 mice at days 6 and 12 post-challenge. At day 6, miRs significantly downregulated in the lower GT were miR-125b-5p, -16, -214, -23b, -135a, -182, -183, -30c, and -30e while -146 and -451 were significantly upregulated, profiles not exhibited at day 12 post-bacterial challenge. Significant differences in miR-125b-5p (+5.06-fold change), -135a (+4.9), -183 (+7.9), and -182 (+3.2) were observed in C. muridarum-infected CD4(-/-) compared to WT mice. In silico prediction and mass spectrometry revealed regulation of miR-135a and -182 and associated proteins, that is, heat-shock protein B1 and alpha-2HS-glycoprotein. This study provides evidence on regulation of miRs following genital chlamydial infection suggesting a role in pathogenesis and host immunity. © 2014 John Wiley & Sons A/S.

To compare the effectiveness of 5% benzocaine gel and placebo gel on reducing pain caused by fixed orthodontic appliance activation. Thirty subjects (15-25 years) undergoing fixed orthodontics. A randomized, double-blind, placebo-controlled and cross-over clinical trial study was conducted. Subjects were asked to apply a placebo gel and 5% benzocaine gel, exchangeable in two consecutive appointments, twice a day for 3 days and mark their level of pain on a VAS scale. The pain severity was evaluated by means of Mann-Whitney U-test for comparing two gel groups, Kruskal-Wallis nonparametric test for overall differences and post hoc test of Dunnett for paired multiple comparisons. p-value was assigned <0.05. The overall mean value of pain intensity for benzocaine and placebo gels was 0.89 and 1.15, respectively. The Mann-Whitney U-test indicated that there was no significant difference between overall pain in both groups (mean difference = 0.258 p ˂ 0.21). For both groups, pain intensity was significantly lower at 2, 6 and 24 h compared with pain experienced at days 2, 3 and 7. Benzocaine gel caused a decrease in pain perception at 2 h compared with placebo gel. Peak pain intensity was at 2 h for placebo gel and at 6 h for benzocaine gel, followed by a decline in pain perception from that point to day 7 for both gels. © 2016 John Wiley & Sons A/S.

The cytomegalovirus (CMV) donor-positive/recipient-positive (D+/R+) population is the largest proportion of renal transplant recipients (RTR). Guidelines for prevention of CMV in the intermediate-risk D+/R+ population include prophylaxis with valganciclovir (VGCV) 900 mg/day for 3 months. This study is the first head-to-head analysis, to our knowledge, comparing the efficacy and safety CMV prophylaxis of VGCV 450 vs 900 mg/day for 3 months in D+/R+ RTR. A multicenter, retrospective analysis evaluated 478 adult RTR between January 2008 and October 2011. Study participants received VGCV 450 mg/day (Group 1; n=398) or 900 mg/day (Group 2; n=89)×3 months for CMV prophylaxis. All VGCV was adjusted for renal function. All groups included in this study received study-approved induction and maintenance immunosuppression regimens. The primary endpoint was incidence of CMV disease at 12 months. The rates of graft loss, patient survival, T-cell and/or antibody-mediated rejection, hematological adverse events, opportunistic infections, and early VGCV discontinuation were evaluated. Patient demographics were comparable, but had significant differences in ethnicity and donor type between the groups. The occurrence of CMV disease at 12 months was similar between the groups (3.5% vs 3.4%; P=1.000). Log-rank test found no statistically significant difference in the time to development of CMV between the 2 groups (P=.939). © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

4-Nitrophenol (PNP) is well known as an environmental endocrine disruptor. The aim of this study was to clarify the mechanism of PNP-induced liver damage and determine the regulatory involvement of the aryl hydrocarbon receptor (AhR) signaling pathway and associated gene expression. Immature male Wistar-Imamichi rats (28 days old) were randomly divided into control and PNP groups, which consisted of 1- and 3-day exposure (1 DE and 3 DE, respectively) and 3-day exposure followed by 3-day recovery (3 DE + 3 DR), groups. Each group was administered the vehicle or PNP (200 mg kg -1 body weight). The body and liver weight were significantly decreased in the 3 DE group. The mRNA expression levels of estrogen receptor-α (ERα), glutathione S-transferase (GST) and AhR exhibited a significant increase in the 1 DE group whereas, in contrast, that of cytochrome P450 (CYP) 1A1 decreased significantly in the 3 DE +3 DR group. AhR and CYP1A1 proteins were detected in the cytoplasm of hepatocytes of the 1 DE and 3 DE +3 DR groups whereas the ERα protein was found in the hepatocyte nuclei of the 1 DE and 3 DE groups. The present study demonstrates that PNP activated the AhR signaling pathway and regulated related CYP1A1 and GST gene expression in the liver. Copyright © 2016 John Wiley & Sons, Ltd.

Ground-water hydrology and simulation of ground-water flow at Operable Unit 3 and surrounding region, U.S. Naval Air Station, Jacksonville, Florida

The Naval Air Station, Jacksonville (herein referred to as the Station), occupies 3,800 acres adjacent to the St. Johns River in Duval County, Florida. Operable Unit 3 (OU3) occupies 134 acres on the eastern side of the Station and has been used for industrial and commercial purposes since World War II. Ground water contaminated by chlorinated organic compounds has been detected in the surficial aquifer at OU3. The U.S. Navy and U.S. Geological Survey (USGS) conducted a cooperative hydrologic study to evaluate the potential for ground water discharge to the neighboring St. Johns River. A ground-water flow model, previously developed for the area, was recalibrated for use in this study. At the Station, the surficial aquifer is exposed at land surface and forms the uppermost permeable unit. The aquifer ranges in thickness from 30 to 100 feet and consists of unconsolidated silty sands interbedded with local beds of clay. The low-permeability clays of the Hawthorn Group form the base of the aquifer. The USGS previously conducted a ground-water investigation at the Station that included the development and calibration of a 1-layer regional ground-water flow model. For this investigation, the regional model was recalibrated using additional data collected after the original calibration. The recalibrated model was then used to establish the boundaries for a smaller subregional model roughly centered on OU3. Within the subregional model, the surficial aquifer is composed of distinct upper and intermediate layers. The upper layer extends from land surface to a depth of approximately 15 feet below sea level; the intermediate layer extends from the upper layer down to the top of the Hawthorn Group. In the northern and central parts of OU3, the upper and intermediate layers are separated by a low-permeability clay layer. Horizontal hydraulic conductivities in the upper layer, determined from aquifer tests, range from 0.19 to 3.8 feet per day. The horizontal hydraulic conductivity in the intermediate layer, determined from one aquifer test, is 20 feet per day. An extensive stormwater drainage system is present at OU3 and the surrounding area. Some of the stormwater drains have been documented to be draining ground water from the upper layer of the surficial aquifer, whereas other drains are only suspected to be draining ground water. The subregional model contained 78 rows and 148 columns of square model cells that were 100 feet on each side. Vertically, the surficial aquifer was divided into two layers; layer 1 represented the upper layer and layer 2 represented the intermediate layer. Steady-state ground-water flow conditions were assumed. The model was calibrated to head data collected on October 29 and 30, 1996. After calibration, the model matched all 67 measured heads to within the calibration criterion of 1 foot; and 48 of 67 simulated heads (72 percent) were within 0.5 foot. Model simulated recharge rates ranged from 0.4 inch per year in areas that were largely paved to 13.0 inches per year in irrigated areas. Simulated hydraulic conductivities in the upper layer at OU3 ranged from 0.5 foot per day in the north to 1.0 foot per day in the south. Simulated vertical leakance between the upper and intermediate layers ranged from 1.0x10-6 per day in an area with low-permeability clays to 4.3x10-2 per day in an area that had been dredged. Simulated transmissivities in the intermediate layer ranged from 25 feet squared per day in an area of low-permeability channel-fill deposits to a high of 1,200 feet squared per day in areas covering most of OU3. Simulated riverbed conductances ranged from 4 to 60 feet squared per day and simulated bottom conductances of leaking stormwater drains ranged from 5 to 20 feet squared per day. The direction and velocity of ground-water flow was determined using particle-tracking techniques. Ground-water flow in the upper layer was generally eastward toward the St. Johns River. However, leaking stormwat
