    Aim: Brain metastases (BMs) are a common event in the progression of many human cancers. The aim of this study was to evaluate the potential prognostic factors for the clinical identification of a subgroup of patients that could benefit from whole brain conformal radiotherapy (WBRT). Materials and Methods: From January 2010 to February 2014, 80 patients with a diagnosis of BMs underwent WBRT at our Radiation Oncology Department, San Luigi Hospital, Italy. Among them, 36 medical records were retrospective reviewed. Gender, age, Karnofsky performance status (KPS), number of BMs on computed tomography and/or magnetic resonance images, presence or absence of perilesional edema, presence or absence of necrosis pattern, and histology of primary tumor were analyzed. Univariate and multivariate analyses were performed. Results: In our cohort of patients, significant prognostic factors for 20 months overall survival was KPS> 70, while a statistical trend (P = 0.098) was registered regarding primary breast. Conclusion: WBRT can be still considered a standard and effective treatment in patients with BMs. High KPS and breast cancer primary tumor seem to be useful parameters for characterize a subgroup of patients with more favorable prognosis.

    Simple and low-cost tools to monitor the risk profile of patients on peritoneal dialysis (PD) at high risk of complications and mortality are scarce. One of the tools available to monitor the variation in vitality and dependence levels is the Karnofsky performance status (KPS). This study analyzed the average trends and variation of KPS during the 12 months before death and its independent value in predicting patients' survival. The data were compiled from the BRAZPD II multi-center study, performed in Brazil between 2004 and 2011. For the analysis of KPS dynamics, we included patients with at least 12 months of follow-up on PD and who had a fatal event during the follow-up. The following covariables were evaluated: age, gender, ethnicity, educational level, and presence of diabetes. We used the linear regression model to present the results: the log (time) before death was represented by the regression variable and KPS was the response. We also analyzed the independent impact of baseline KPS on patients' survival. From the population of 9,905 patients enrolled in the BRAZPD study, 4,133 survived 12 months on PD and were included in the analysis. There was a gradual decline in the KPS scores, which accelerated in the last 2 months before death. These changes were similar irrespective of age, race, family income, gender, diabetes, PD modality, and education level. We observed 989 fatal events in this population during the observation period, and the KPS score was identified as an independent predictor for mortality in this cohort. This study demonstrates for the first time the dynamics of KPS before death in PD patients, indicating a progressive and accelerated decline of KPS in the 12 months before patients died. In addition, KPS was an independent predictor of mortality in this population.

    Purpose: To determine prognostic factors that allow the selection of melanoma patients with advanced intra- and extracerebral metastatic disease for palliative whole-brain radiation therapy (WBRT) or best supportive care. Methods and Materials: This was a retrospective study of 87 patients who underwent palliative WBRT between 1988 and 2009 for progressive or multiple cerebral metastases at presentation. Uni- and multivariate analysis took into account the following patient- and tumor-associated factors: gender and age, Karnofsky performance status (KPS), neurologic symptoms, serum lactate dehydrogenase (LDH) level, number of intracranial metastases, previous resection or stereotactic radiosurgery of brain metastases, number of extracranial metastasis sites, and local recurrences as well as regional lymph node metastases at the time of WBRT. Results: In univariate analysis, KPS, LDH, number of intracranial metastases, and neurologic symptoms had a significant influence on overall survival. In multivariate survival analysis, KPS and LDH remained as significant prognostic factors, with hazard ratios of 3.3 (95% confidence interval [CI] 1.6-6.5) and 2.8 (95% CI 1.6-4.9), respectively. Patients with KPS ≥70 and LDH ≤240 U/L had a median survival of 191 days; patients with KPS ≥70 and LDH >240 U/L, 96 days; patients with KPS <70 and LDH ≤240 U/L, 47 days; and patients with KPS <70 and LDH >240 U/L, only 34 days. Conclusions: Karnofsky performance status and serum LDH values indicate whether patients with advanced intra- and extracranial tumor manifestations are candidates for palliative WBRT or best supportive care.

    Full Text Available Abstract Background Surgery after (chemoradiation (RCTX/RTX is felt to be plagued with a high incidence of wound healing complications reported to be as high as 70%. The additional use of vascularized flaps may help to decrease this high rate of complications. Therefore, we examined within a retrospective single-institutional study the peri--and postoperative complications in patients who underwent surgery for salvage, palliation or functional rehabilitation after (chemoradiation with regional and free flaps. As a second study end point the Karnofsky performance status (KPS was determined preoperatively and 3 months postoperatively to assess the impact of such extensive procedures on the overall performance status of this heavily pretreated patient population. Findings 21 patients were treated between 2005 and 2010 in a single institution (17 male, 4 female for salvage (10/21, palliation (4/21, or functional rehabilitation (7/21. Overall 23 flaps were performed of which 8 were free flaps. Major recipient site complications were observed in only 4 pts. (19% (1 postoperative haemorrhage, 1 partial flap loss, 2 fistulas and major donor site complications in 1 pt (wound dehiscence. Also 2 minor donor site complications were observed. The overall complication rate was 33%. There was no free flap loss. Assessment of pre- and postoperative KPS revealed improvement in 13 out of 21 patients (62%. A decline of KPS was noted in only one patient. Conclusions We conclude that within this (chemoradiated patient population surgical interventions for salvage, palliation or improve function can be safely performed once vascularised grafts are used.

    Oncologists usually base treatment decision on the assessment of patients' performance status (PS). This study was undertaken to explore the ability of KPS to correctly assess the PS of elderly cancer patients, comparing it to a validated geriatric tool named Physical Performance Test (PPT). One single examiner assessed elderly cancer patients' PS at registration in our institution and performed the PPT on patients with KPS ≥ 60. A sample of 152 patients actually underwent PPT. A low refusal rate was observed (PPT scores. Patients' gender and disease stage did not correlate with PPT scores. The KPS seems to be a less accurate tool than the PPT to assess functional status of elderly cancer patients. Then PPT could be used as an inclusion criterion instead of KPS before cancer treatment decision. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Despite progress in the treatment of advanced and metastatic pancreatic cancer (PC), the outcome of this disease remains dismal for the majority of patients.Given the moderate efficacy of treatment, prognostic factors may help to guide treatment decisions. Several trials identified baseline performance status as an important prognostic factor for survival. Unfit patients with a Karnofsky performance status (KPS) below 70% only have a marginal benefit from chemotherapy with gemcitabine (Gem) and may often benefit more from optimal supportive care. Once, however, the decision is taken to apply chemotherapy, KPS may be used to select either mono- or combination chemotherapy. Patients with a good performance status (KPS = 90%-100%) may have a significant and clinically relevant survival benefit from combination chemotherapy. By contrast, patients with a poor performance status (KPS ≤ 80%) have no advantage from intensified therapy and should rather receive single-agent treatment.

    Full Text Available The associations between coping styles, measured by COPE Test, dispositional version (Carver,Scheier and Weintraub, 1989, and Health Status inferred through a performance status, measured by Karnofsky's Index of Behavioral Performance are examined. The study focuses upon 28 oncological in patients. Positive moderate Pearson's correlations were found between these two variables in this correlational-descriptive study. These were interpreted in the following sense: the larger use of the style, the less health status among the scales suppression of competent activities, procrastination of coping, instrumental social support, focusing and releasing of emotions and behavioral disengagement. The active coping scale presented a negative correlationwith regard to Performance Status as a health measure.

  9. Expert status and performance.

    Full Text Available Expert judgements are essential when time and resources are stretched or we face novel dilemmas requiring fast solutions. Good advice can save lives and large sums of money. Typically, experts are defined by their qualifications, track record and experience. The social expectation hypothesis argues that more highly regarded and more experienced experts will give better advice. We asked experts to predict how they will perform, and how their peers will perform, on sets of questions. The results indicate that the way experts regard each other is consistent, but unfortunately, ranks are a poor guide to actual performance. Expert advice will be more accurate if technical decisions routinely use broadly-defined expert groups, structured question protocols and feedback.

    Individuals who are diagnosed with end-stage renal disease (ESRD) undergo major changes in lifestyle. The present cross-sectional study was conducted to identify the relationship between patients who undergo hemodialysis (HD) and their performance status, and how it is influenced by the presence of the level of depression and anxiety. A total of 50 patients were recruited from HD centers in and around Chennai. The patients were screened using the General Health Questionnaire to screen for co-morbid psychiatric conditions. The patients were assessed for depression and anxiety, and their performance status was assessed using Beck's Depression Inventory, Beck's Anxiety Inventory, and Karnofsky Performance Status. The study findings indicate that there is a positive correlation between anxiety and depression in ESRD patients. The findings also indicated that depression and anxiety are positively correlated with the performance status of ESRD patients. The duration on, as well as the frequency of dialysis, also correlated with the performance status of ESRD patients. It can be concluded that anxiety and depression are prevalent among ESRD patients and that they interfere with the performance status; additionally, duration on dialysis also interferes with performance status. Addressing depression and anxiety can help in enhancing the patient's performance status.

    Full Text Available Factors associated with physical well being were examined in adults with end-stage renal disease (ESRD in two large hemodialysis units of the Royal Medical Services in Jordan. Utilizing the Karnofski scale we measured the functional status of 200 Patients who had been on maintenance hemodialysis for at least 12 months. A Marnofski scale of less than 70 incidents frank disability (Inability to perform routine living activities without assistance, in addition current vocational status was assessed as well as any existing comorbid conditions. The mean age of the study group was 45.2 years (range 16 to 70 and included 108 (54% males and 92 (46% females, there were 39 (19.5% diabetic patients and 27 (13.5% patients were receiving erythropoietin (EPO. The mean hematocrit of the entire group was 27.8%. As measured by Karnofski scale, 64 (32% of the patients were unable to perform routine living activity without assistance; dependence on wheelchair was reported by 9 (4.5% patients. The mean comorbidity index of patients who scored less than 70 on the Karnofski scale was 1.5 compared to 0.7 for those who scored at least 70 on the same scale (p< 0.001. Analysis of factors showed that age and diabetes mellitus affected functional status. Of the laboratory variables measured, only serum albumin concentration correlated significant with Karnofski scale. Fourteen (21.8% of the patients who scored below 70, had serum albumin concentration above 40g/L compared to 66 (48.5% of the patients who scored at least 70 on the Karnofski scale (p< 0.001. We conclude that a significant proportion of patients on maintenance hemodialysis is functionally disabled. The elderly, diabetics, patients with high co-morbidity index and those with low serum albumin are most likely to have poor functional status.

    Surgical treatment strategies for proximal femur metastasis have been reported with mixed results. Little is known about risk factor for implant failure except for longer patient survival. Therefore, we determined whether implant survivorship differed among treatment strategies, as well as risk factors for implant failure. We retrospectively reviewed a consecutive 106 patients with proximal femur metastasis treated with prosthesis replacement (n = 38), intramedullary nail (n = 32), and dynamic hip screw (DHS) (n = 36). Eastern Cooperative Oncology Group (ECOG) scale and Karnofsky index were used to evaluate functional outcome. Patient characteristics and postoperative ambulatory performance status were assessed for their values in determining implant failure. Overall implant failure rate was 11.3% (12 of 106). Prosthesis replacement was related to better implant survivorship (P = 0.041), without mechanical failures. On the contrary, 7 of the 10 implant failures in the fixation group were considered mechanical failures. Better postoperative ambulatory status (ECOG ≤ 2) was a risk factor for implant failure (P = 0.03). Notably, for patients with poor ambulatory status (ECOG ≥ 3), implant survivorship was not different among choice of implants. In conclusion, prosthesis replacement would be a more durable option in the treatment of proximal femur metastasis. Postoperative ambulatory status could be an additional consideration. For patients with poor expected ambulatory performance status, fixation with intramedullary nail or DHS might be considered for a less technical demanding procedure.

    Visible Infrared Imager Radiometer Suite (VIIRS) instrument on-board the National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) satellite is scheduled for launch in October, 2011. It is to provide satellite measured radiance/reflectance data for both weather and climate applications. Along with radiometric calibration, geometric characterization and calibration of Sensor Data Records (SDRs) are crucial to the VIIRS Environmental Data Record (EDR) algorithms and products which are used in numerical weather prediction (NWP). The instrument geometric performance includes: 1) sensor (detector) spatial response, parameterized by the dynamic field of view (DFOV) in the scan direction and instantaneous FOV (IFOV) in the track direction, modulation transfer function (MTF) for the 17 moderate resolution bands (M-bands), and horizontal spatial resolution (HSR) for the five imagery bands (I-bands); 2) matrices of band-to-band co-registration (BBR) from the corresponding detectors in all band pairs; and 3) pointing knowledge and stability characteristics that includes scan plane tilt, scan rate and scan start position variations, and thermally induced variations in pointing with respect to orbital position. They have been calibrated and characterized through ground testing under ambient and thermal vacuum conditions, numerical modeling and analysis. This paper summarizes the results, which are in general compliance with specifications, along with anomaly investigations, and describes paths forward for characterizing on-orbit BBR and spatial response, and for improving instrument on-orbit performance in pointing and geolocation.

    found in 32% of the patients. Impaired balance and coordination were detected in 34.8% and 15.6% of the patients. Low physical performance was found in 72.5% of the patients (6min walk test: 31.6% severely; 40.9% moderately impaired and 43.8% required considerable assistance when the Karnofsky index was applied. Malnutrition was found in 62.5% of the patients (34.37% moderately and severely malnourished and 28.13% mildly malnourished. Chi-square analysis showed no association between Child-Pugh classification and nutritional status, the 6min walk test and Karnofsky index. The association between the two functional tests was statistically significant (p<0.001. CONCLUSION: The results show that physical impairment and nutritional deficit were highly prevalent in the patients studied, independent of the degree of hepatic dysfunction evaluated by the traditional Child-Pugh classification.

    This memo summarizes the current status of the Ceph block storage service as it is used for OpenStack Cinder Volumes and Glance Images as of May 2014. We present the block storage activity on the current cluster, measuring IOPS and latencies, and present a cost/benefit analysis of using SSDs to optimize the cost and performance efficiency of the service. During tests in collaboration with IT-CF, we have concluded that by adding SSDs as the synchronous write journals (used to guarantee data durability), we are able increase the IOPS capacity by 4-5 times, at a cost of decreasing the available volume by 20%. Further, the testing has shown that the Ceph implementation is able to operate at the limit of the hardware performance; software-induced performance limitations were not yet observed in either the spinning disk or SSD configurations. In addition, we believe that increasing small write performance with SSDs is applicable only to the block storage use-case; high-bandwidth use-cases such as physics data stora...

    2003-03-01

    Results from two experiments suggest that stereotype-threat effects are special cases of a more general process involving the need to maintain or enhance status. We hypothesized that situations capable of confirming a performance stereotype might represent either a threat to status or an opportunity for enhancement of status, depending on the nature of the stereotype. The positive relationship between baseline testosterone and status sensitivity led us to hypothesize that high testosterone levels in males and females would amplify existing performance expectations when gender-based math-performance stereotypes were activated. In Study 1, high-testosterone females performed poorly on a math test when a negative performance stereotype was primed. In Study 2, high-testosterone males excelled on a math test when a positive performance stereotype was primed. The moderating effect of testosterone on performance suggests that a stereotype-relevant situation is capable of conferring either a loss or a gain of status on targets of the stereotype.

    The National Ignition Facility (NIF) laser has been designed to support high energy density science (HEDS), including the demonstration of fusion ignition through Inertial Confinement. NIF operated a single ''quad'' of 4 beams from December 2002 through October 2004 in order to gain laser operations experience, support target experiments, and demonstrate laser performance consistent with NIF's design requirement. During this two-year period, over 400 Main Laser shots were delivered at 1{omega} to calorimeters for diagnostic calibration purposes, at 3{omega} to the Target Chamber, and at 1{omega}, 2{omega}, and 3{omega} to the Precision Diagnostics System (PDS). The PDS includes its own independent single beam transport system, NIF design frequency conversion hardware and optics, and laser sampling optics that deliver light to a broad range of laser diagnostics. Highlights of NIF laser performance will be discussed including the results of high energy 2{omega} and 3{omega} experiments, the use of multiple focal spot beam conditioning techniques, the reproducibility of laser performance on multiple shots, the generation on a single beam of a 3{omega} temporally shaped ignition pulse at full energy and power, and recent results on full bundle (8 beamline) performance. NIF's first quad laser performance meets or exceeds NIF's design requirements.

    The STIS (Space Telescope Imaging Spectrograph) is a second generation Hubble instrument scheduled to fly in 1997. Through a variety of modes, the instrument will provide spectral resolutions from R approximately 50 in the objective spectroscopy mode to 100,000 in the high resolution echelle mode in the wavelength region from 115 to 1000 nm. In the UV the instrument employs two MAMA (Multimode Anode Microchannel plate Arrays) 1024 by 1024 pixel detectors, which provide high DQE (Detective Quantum Efficiency), and good dynamic range and resolution. The current progress and performance of these detectors are reported, illustrating that the technology is mature and that the performance is very close to flight requirements.

    Full Text Available Glioblastoma Multiforme (GBM is an aggressive primary brain neoplasm with dismal prognosis. Based on successful phase III trials, 60 Gy involved-field radiotherapy in 30 fractions over 6 weeks (Standard RT with concurrent and adjuvant temozolomide is currently the standard of care. In this disease, age and Karnofsky Performance Status (KPS are the most important prognostic factors. For elderly patients, clinical trials comparing standard RT with radiotherapy abbreviated to 40 Gy in 15 fractions over 3 weeks demonstrated similar outcomes, indicating shortened radiotherapy may be an appropriate option for elderly patients. However, these trials did not include temozolomide chemotherapy, and included patients with poor KPS, possibly obscuring benefits of more aggressive treatment for some elderly patients. We conducted a prospective Phase II trial to examine the efficacy of a hypofractionated radiation course followed by a stereotactic boost with concurrent and adjuvant temozolomide chemotherapy in elderly patients with good performance status. In this study, patients 65 years and older with a KPS >70 and histologically confirmed GBM received 40 Gy in 15 fractions with 3D conformal technique followed by a 1-3 fraction stereotactic boost to the enhancing tumor. All patients also received concurrent and adjuvant temozolomide. Patients were evaluated 1 month post-treatment and every 2 months thereafter. Between 2007 and 2010, 20 patients (9 males and 11 females were enrolled in this study. The median age was 75.4 years (range 65-87 years. At a median follow-up of 11 months (range 7-32 months, 12 patients progressed and 5 are alive. The median progression free survival was 11 months and the median overall survival was 13 months. There was no additional toxicity. These results indicate that elderly patients with good KPS can achieve outcomes comparable to the current standard of care using an abbreviated radiotherapy course, radiosurgery boost and

    The aim of this study was evaluation of nutritional status in attack and stable chronic obstructive pulmonary disease (COPD) cases, and investigating the relation between nutrition parameters and pulmonary functions, exercise performance and general healthy status. Anthropometric measures of 10 cases with attack (group 1), 14 stabilized COPD cases (group 2) and 10 control cases (group 3) were evaluated by measuring serum albumin, transferrin, tumor necrosis factor-alpha (TNF-alpha) levels, and fat-free mass (FFM) levels. Six minutes walking test (mwt) and SGRQ questionnaire were performed. Body mass index (BMI) of group 1 and 2 were significantly lower than group 3 (p= 0.023, p= 0.008, respectively). Albumin levels were significantly lower in group 1 than group 2 (pnutritional defect was seen and a significant relation was observed between nutrition parameters and effort capacity.

    As the world population ages, the comorbidity burden in acute myeloid leukemia (AML) patients increases. Evidence on how to integrate comorbidity measures into clinical decision-making is sparse. We determined the prognostic impact of comorbidity and WHO Performance Status (PS) on achievement......-term mortality [adjusted 90-day MR, PS⩾2=3.43 (95%CI=2.30-5.13); adjusted 91-day-3-year MR=1.35 (95%CI=1.06-1.74)]. We propose that more patients with comorbidity may benefit from intensive chemotherapy.Leukemia accepted article preview online, 5 August 2014; doi:10.1038/leu.2014.234....

    Since launch, both Terra and Aqua MODIS instruments have continued to operate and make measurements of the earth's top of atmospheric (TOA) radiances and reflectance. MODIS collects data in 36 spectral bands covering wavelengths from 0.41 to 14.4 μm. These spectral bands and detectors are located on four focal plane assemblies (FPAs). MODIS on-board calibrators (OBC) include a spectro-radiometric calibration assembly (SRCA), which was designed to characterize and monitor sensor spatial and spectral performance, such as on-orbit changes in the band-to-band registration (BBR), modulation transfer function (MTF), spectral band center wavelengths (CW) and bandwidths (BW). In this paper, we provide a status update of MODIS spatial and spectral characterization and performance, following a brief description of SRCA functions and on-orbit calibration activities. Sensor spatial and spectral performance parameters derived from SRCA measurements are introduced and discussed. Results show that on-orbit spatial performance has been very stable for both Terra and Aqua MODIS instruments. The large BBR shifts in Aqua MODIS, an issue identified pre-launch, have remained the same over its entire mission. On-orbit changes in CW and BW are less than 0.5 nm and 1 nm, respectively, for most VIS/NIR spectral bands of both instruments.

    The Atmospheric Infrared Sounder (AIRS) is a hyperspectral infrared instrument on the EOS Aqua Spacecraft, launched on May 4, 2002. AIRS has 2378 infrared channels ranging from 3.7 μm to 15.4 μm and a 13.5 km footprint at nadir. AIRS is a "facility" instrument developed by NASA as an experimental demonstration of advanced technology for remote sensing and the benefits of high resolution infrared spectra to science investigations. AIRS, in conjunction with the Advanced Microwave Sounding Unit (AMSU), produces temperature profiles with 1K/km accuracy on a global scale, as well as water vapor profiles and trace gas amounts for CO2 , CO, SO2 , O3 and CH4. AIRS data are used for weather forecasting, climate process studies and validating climate models. The AIRS instrument has far exceeded its required design life of 5 years, with nearly 13 years of routine science operations that began on August 31, 2002. While the instrument has performed exceptionally well, with little sign of wear, the AIRS Project continues to monitor and maintain the health of AIRS, characterize its behavior and improve performance where possible. Radiometric stability has been monitored and trending shows better than 16 mK/year stability. Spectral calibration stability is better than 1 ppm/year. At this time we expect the AIRS to continue to perform well into the next decade. This paper contains updates to previous instrument status reports, with emphasis on the last three years.

    The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory contains a 192-beam 3.6 MJ neodymium glass laser that is frequency converted to 351nm light. It has been designed to support high energy density science (HEDS), including the demonstration of fusion ignition through Inertial Confinement. To meet this goal, laser design criteria include the ability to generate pulses of up to 1.8-MJ total energy at 351nm, with peak power of 500 TW and precisely-controlled temporal pulse shapes spanning two orders of magnitude. The focal spot fluence distribution of these pulses is conditioned, through a combination of special optics in the 1{omega} (1053 nm) portion of the laser (continuous phase plates), smoothing by spectral dispersion (SSD), and the overlapping of multiple beams with orthogonal polarization (polarization smoothing). In 2006 and 2007, a series of measurements were performed on the NIF laser, at both 1{omega} and 3{omega} (351 nm). When scaled to full 192-beam operation, these results lend confidence to the claim that NIF will meet its laser performance design criteria and that it will be able to simultaneously deliver the temporal pulse shaping, focal spot conditioning, peak power, shot-to-shot reproducibility, and power balance requirements of indirect-drive fusion ignition campaigns. We discuss the plans and status of NIF's commissioning, and the nature and results of these measurement campaigns.

    NXE:3300B scanners have been operational at customer sites since almost two years, and the NXE:3350B, the 4th generation EUV system, has started shipping at the end of 2015. All these exposure tools operate using MOPA pre-pulse source technology, which enabled significant productivity scaling, demonstrated at customers and at ASML. Having achieved the required throughput to support device development, the main priority of the ASML EUV program has shifted towards improving stability and availability. Continuous progresses in defectivity reduction and in the realization of a reticle pellicle are taking place at increased speed. Today's overlay and imaging results are in line with the requirements of 7nm logic devices; Matched Machine overlay to ArF immersion below 2.5 nm and full wafer CDU performance of less than 1.0nm are regularly achieved. The realization of an intensity loss-less illuminator and improvements in resist formulation are significant progress towards enabling the use of EUV technology for 5nm logic devices at full productivity. This paper will present an overview of the status of the ASML EUV program and product roadmap by reviewing the current performance and on-going developments in productivity, imaging, overlay and mask defectivity reduction.

    Full Text Available The Sea-wave Slot-cone Generator (SSG is a Wave Energy Converter based on the wave overtopping principle; it employs several reservoirs placed on top of each other, in which the energy of incoming waves is stored as potential energy. Then, the captured water runs through turbines for electricity production. The system works under a wide spectrum of different wave conditions, giving a high overall efficiency. It can be suitable for shoreline and breakwater applications and presents particular advantages, such as sharing structure costs, availability of grid connection and recirculation of water inside the harbor, as the outlet of the turbines is on the rear part of the system. Recently, plans for the SSG pilot installations are in progress at the Svaaheia site (Norway, the port of Hanstholm (Denmark and the port of Garibaldi (Oregon, USA. In the last-mentioned two projects, the Sea-wave Slot-cone Generator technology is integrated into the outer harbor breakwater and jetty reconstruction projects. In the last years extensive studies have been performed on the hydraulic and the structural response of this converter, with the aim of optimizing the design process. The investigations have been conducted by physical model tests and numerical simulations and many results have been published on both conference proceedings and journals. The main scope of this paper is reviewing the most significant findings, to provide the reader with an organic overview on the present status of knowledge.

  13. Fail or flourish? Cognitive appraisal moderates the effect of solo status on performance.

    2008-09-01

    When everyone in a group shares a common social identity except one individual, the one who is different from the majority has solo status. Solo status increases one's visibility and performance pressure, which may result in stress. Stress has divergent effects on performance, and individuals' response to stressful situations is predicted by their cognitive appraisal (challenge or threat) of the situation. Two experiments test the hypothesis that cognitive appraisal moderates the effect of solo status on performance. Experiment 1 finds that at relatively high appraisal levels (resources exceed demands), solo status improves men's and women's performance; at relatively low appraisal levels, solo status hurts performance. Experiment 2 replicates this effect for solo status based on minimal group assignment. Results suggest that for individuals who feel challenged and not threatened by their work, it may help to be a solo.

  15. Hierarchy stability moderates the effect of status on stress and performance in humans.

    2017-01-03

    High social status reduces stress responses in numerous species, but the stress-buffering effect of status may dissipate or even reverse during times of hierarchical instability. In an experimental test of this hypothesis, 118 participants (57.3% female) were randomly assigned to a high- or low-status position in a stable or unstable hierarchy and were then exposed to a social-evaluative stressor (a mock job interview). High status in a stable hierarchy buffered stress responses and improved interview performance, but high status in an unstable hierarchy boosted stress responses and did not lead to better performance. This general pattern of effects was observed across endocrine (cortisol and testosterone), psychological (feeling in control), and behavioral (competence, dominance, and warmth) responses to the stressor. The joint influence of status and hierarchy stability on interview performance was explained by feelings of control and testosterone reactivity. Greater feelings of control predicted enhanced interview performance, whereas increased testosterone reactivity predicted worse performance. These results provide direct causal evidence that high status confers adaptive benefits for stress reduction and performance only when the social hierarchy is stable. When the hierarchy is unstable, high status actually exacerbates stress responses.

    The Soil Moisture Active Passive (SMAP) observatory was launched January 31, 2015, and its L-band radiometer and radar instruments became operational since mid-April 2015. The SMAP radiometer has been operating flawlessly, but the radar transmitter ceased operation on July 7. This paper provides a status summary of the calibration and validation of the SMAP instruments and the quality assessment of its soil moisture and freeze/thaw products. Since the loss of the radar in July, the SMAP project has been conducting two parallel activities to enhance the resolution of soil moisture products. One of them explores the Backus Gilbert optimum interpolation and de-convolution techniques based on the oversampling characteristics of the SMAP radiometer. The other investigates the disaggregation of the SMAP radiometer data using the European Space Agency's Sentinel-1 C-band synthetic radar data to obtain soil moisture products at about 1 to 3 kilometers resolution. In addition, SMAP's L-band data have found many new applications, including vegetation opacity, ocean surface salinity and hurricane ocean surface wind mapping. Highlights of these new applications will be provided.

  17. Predicting performance expectations from affective impressions: linking affect control theory and status characteristics theory.

    Science.gov (United States)

    Dippong, Joseph; Kalkhoff, Will

    2015-03-01

    Affect control theory (ACT) and status characteristics theory (SCT) offer separate and distinct explanations for how individuals interpret and process status- and power-relevant information about interaction partners. Existing research within affect control theory offers evidence that status and power are related to the affective impressions that individuals form of others along the dimensions of evaluation and potency, respectively. Alternately, status characteristics theory suggests that status and power influence interaction through the mediating cognitive construct of performance expectations. Although both theories have amassed an impressive amount of empirical support, research has yet to articulate theoretical and empirical connections between affective impressions and performance expectations. The purpose of our study is to address this gap. Elaborating a link between ACT and SCT in terms of their central concepts can serve as a stepping stone to improving the explanatory capacity of both theories, while providing a potential bridge by which they can be employed jointly.

  18. Iron supplementation for female athletes: effects on iron status and performance outcomes.

    DellaValle, Diane M

    2013-01-01

    Iron is an essential micronutrient involved in oxidative metabolism and critical to exercise performance. The prevalence of iron deficiency (ID) is much higher in active women for a variety of reasons, and poor iron status has been shown to be detrimental to overall health as well as physical performance. Iron status can be assessed using a number of indicators; however clinical cut-offs for active populations remain controversial. Randomized, placebo-controlled supplementation trials of iron-depleted female athletes have shown that oral iron supplementation in doses of 100-mg FeSO4·d (approximately 20 mg elemental iron) improves iron status and may improve measures of physical performance. It is recommended that female athletes most at risk of ID be screened at the beginning of and during the training season using hemoglobin and serum ferritin, and appropriate dietary and/or supplementation recommendations be made to those with compromised iron status.

    Landsat 8 and its two Earth imaging sensors, the Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) have been operating on-orbit for 2 ½ years. Landsat 8 has been acquiring substantially more images than initially planned, typically around 700 scenes per day versus a 400 scenes per day requirement, acquiring nearly all land scenes. Both the TIRS and OLI instruments are exceeding their SNR requirements by at least a factor of 2 and are very stable, degrading by at most 1% in responsivity over the mission to date. Both instruments have 100% operable detectors covering their cross track field of view using the redundant detectors as necessary. The geometric performance is excellent, meeting or exceeding all performance requirements. One anomaly occurred with the TIRS Scene Select Mirror (SSM) encoder that affected its operation, though by switching to the side B electronics, this was fully recovered. The one challenge is with the TIRS stray light, which affects the flat fielding and absolute calibration of the TIRS data. The error introduced is smaller in TIRS band 10. Band 11 should not currently be used in science applications.

    Although nutritional status plays an important part in the physical performance and disability of older people, this relationship has been little studied in developing countries. A study on the effects of nutritional status on the physical performance and functional status of elderly people living in rural areas of the Peruvian Andes. The study concerned 222 people aged ≥65 years living in a rural area of the Peruvian Andes. The Mini-Nutritional Assessment (MNA) was used to classify participants as malnourished (MNA = 24). The short physical performance battery (SPPB) and six-minute walking test (6MWT) were used to measure participants' physical performance. Disabilities were investigated by assessing participants' self-reported difficulty in performing one or more basic activities of daily living (ADL), and instrumental activities of daily living (IADL). The prevalence of malnutrition was 9.4 %, and more than half of our samples were at risk of malnutrition. After adjusting for potential confounders, malnourished individuals performed significantly worse than the other MNA groups in the SPPB (p for trend=0.001), 6MWT and IADL (p for trend nutritional status was found significantly associated with poor physical performance and poor functional status in elderly Peruvian individuals.

    The EXO-200 experiment was created to search for neutrinoless double beta decay (0νββ) using an ultra-low background single-phase time projection chamber. The detector contains 110 kg of active liquid xenon, isotopically enriched in 136Xe, which acts as both the decaying nucleus and the detection medium. The detector has demonstrated excellent energy resolution and background rejection capabilities, and has set a lower limit on the 0νββ decay half-life of 1.1 × 1025 years at 90% C.L. in early 2014. The EXO-200 collaboration has since published several papers on experimental backgrounds and searches for rare or exotic processes. After a two-year data interruption, EXO-200 is now back online with significant hardware improvements, including a radon reduction air system and a front-end electronics upgrade to improve the energy resolution. The improved detector performance since the restart and recent physics results will be presented.

    The reliable thermodynamic database (TDB) is needed for the performance analysis of geological disposal system of high-level radioactive waste (HLW). The thermodynamic database should be based on both reliable experiments and reasonable procedure for data selection. The selected data are required to be validated whether they are available in realistic system, for example, in the groundwater equilibrated with bentonite of engineered barriers in HLW disposal system. In this report, the guidelines for the PNC-TDB development and the procedure are described. Furthermore, results on the PNC-TDB development for Ni, Zr, Sm, U, Am, Cm are reported. Data-set for Ni and Zr was validated by solubility measurements in bentonite-water system. Data-set for Sm was derived from solubility measurements. Reasonable data-set for U appropriate under reducing condition was selected from recent studies. Data-set for Am was generally based on OECD/NEA`s TDB. Data-set for Cm was selected by comparison with experimental data under consideration of conservatism. (author)

    Leptin is an anorexia inductor peptide produced by adipocytes and related to fat mass. Leptin is also produced by fat under proinflammatory cytokine action. Our objective is to study serum leptin levels in relation to nutritional status and acute phase response in advanced-stage non-small cell lung cancer.Seventy-six patients newly diagnosed of non surgical non-small cell lung cancer before chemotherapy treatment and 30 healthy controls were included. BMI, serum leptin and cholesterol levels and lymphocyte count were decreased in lung cancer patients. Cytokine IL-6, TNF-alpha, sTNF-RII, sIL-2R, IL-12, IL-10 and IFN-gamma, and other acute phase reactants as alpha1 antitrypsin, ferritin, CRP and platelets were all raised in patients, whereas the IL-2 was decreased. We found a direct relationship between leptin and other indicators of the status of nutrition, especially total fat mass. We also found a close relationship between the status of nutrition and the performance status (Karnofsky index). However, serum leptin and nutritional status were inversely correlated with acute phase proteins and proinflammatory cytokines, suggesting a stress-type malnutrition. Although serum leptin levels, nutritional status and Karnofsky index are related to survival, at multivariate analysis they all were displaced by the acute phase reaction markers. These results suggest that cancer anorexia and cachexia are not due to a dysregulation of leptin production. Circulating leptin concentrations are not elevated in weight-losing cancer patients and are inversely related to the intensity of the inflammatory response. In advanced lung cancer patients serum leptin concentrations only depend on the total amount of fat.

  7. Taking the reins: the effects of new leader status and leadership style on team performance.

    2011-05-01

    New leaders face a challenging task when they take charge of their teams. They have to determine how best to guide the work process, and they must understand how their behaviors will affect the members of their team. This research examines how a newly assigned team leader's status moderates subordinates' reactions to different leadership styles to affect assessments of the leader's self-confidence and effectiveness, and how this impacts team performance. Across 2 experimental studies, results demonstrate that low-status leaders are rated as more effective when they use a directive style, whereas high-status leaders are viewed as more effective when they use a participative style, and this relationship is mediated by perceptions of self-confidence. In addition, teams whose leaders are viewed more favorably perform better on a complex group task. These findings imply that low-status individuals are able to enhance their level of personal power by drawing on whatever positional power they hold, whereas high-status individuals are better off relying solely on their personal power to influence others. This research also provides a clear demonstration that assessments of new leaders' behaviors are subject to an appraisal that is clouded by observers' status perceptions and attributions.

    The purpose of this study was to obtain a fuller understanding of the association of dietary behaviours, physical status and socio-economic status with academic performance in Korean teenagers. The subjects in this study were 6,463 boys and girls, in grade 5, 8, and 11 in Korea. A self-administered questionnaire and the food-frequency form were used. Grade point average (GPA), height, weight, and physical fitness score for the year were recorded from the school record. The academic performance of students was strongly associated with dietary behaviours, especially with regularity of three meals even after control for parent's education level. Regular breakfast and lunch were more important in grades 5 and 8, while regular dinner was more related with academic performance in grade 11. Small, positive associations of height and physical fitness to academic performance were also found. The relative importance of regularity of meals was greater than that of socio-economic status and physical status in older teenagers. The results of this study suggest that accommodation of better dietary environment and nutrition education for three regular meals is recommended.

  15. Performance analysis of spectrum sensing with multiple status changes in primary user traffic

    In this letter, the impact of primary user traffic with multiple status changes on the spectrum sensing performance is analyzed. Closed-form expressions for the probabilities of false alarm and detection are derived. Numerical results show that the multiple status changes of the primary user cause considerable degradation in the sensing performance. This degradation depends on the number of changes, the primary user traffic model, the primary user traffic intensity and the signal-to-noise ratio of the received signal. Numerical results also show that the amount of degradation decreases when the number of changes increases, and converges to a minimum sensing performance due to the limited sensing period and primary holding time. © 2012 IEEE.

    Full Text Available Using a nationally representative sample of 142 783 middle school (13–15 years old and high school (16–18 years old students in South Korea, this study examined whether (1 overweight and obesity are more likely to be associated with lower self-reported school performance; (2 overweight and obese students are more likely to enrol in a vocational high school as opposed to a general high school; (3 the association between obesity and poorer self-reported school performance is mediated through body image stress and health status. We found that excess weight was negatively associated with self-reported school performance among middle and general high school students, and that obese students had a higher probability of being enrolled in a vocational over a general high school. We did not find strong evidence on the mediating role of body image stress and health status.

    Background Cancer-related fatigue and insomnia are common distressing symptoms and may affect mood and performance status. Objective to describe fatigue, sleep, pain, mood and performance status and the relationships among these variables in 187 patients newly diagnosed with multiple myeloma (MM) and conduct an analysis using the correlates of fatigue. Interventions/Methods Data were from baseline measures from the study, using the Profile of Mood States (POMS) and the Functional Assessment of Cancer Therapy - Fatigue to assess fatigue, the Actigraph to measure sleep, the Wong/Baker Faces Pain Rating Scale to assess pain, the POMS to assess mood, and the 6-minute walk test along with a back/leg/chest dynamometer to test muscle strength to assess performance status. Data analysis consisted of descriptive statistics, Pearson and Spearman rho correlations and multiple regression using fatigue as the dependent variable. All p values were two-sided, and those with model, which included all of these variables along with age, gender and stage of disease, was statistically significant with a large measure of effect. Mood was a significant individual contributor to the model. Conclusions Among patients with MM, fatigue, pain, sleep, mood and functional performance are interrelated. Implications for Practice Interventions are needed to decrease fatigue and pain and to improve sleep, mood and functional performance. PMID:21522061

    Risk of malnutrition is elevated among oncologic patients, and this increases postoperative morbidity and mortality. To study the association between nutritional status and postoperative outcomes in a group of patients with gastrointestinal cancers. We studied 129 patients with diagnosis of digestive cancer, previous to potentially curative surgery. Nutritional status was evaluated through anthropometric measures, Subjective Global Assessment (SGA), dietary intake recalls and routine biochemical parameters. Functional performance was assessed by the Karnofsky index (KI). Cancer stage was classified according to TNM4. During the postoperative period, complications, length of stay at the critical care ward and duration of hospitalization were registered. Thirty days after discharge, patients were contacted, and the appearance of new complications was listed. According to SGA 14.7% of patients were classified as well nourished (A), 57.3% as moderately undernourished or at risk of malnutrition (B) and 27.9% as severely malnourished (C). The incidence of total complications was 25.5%. Nutritional status was not associated with cancer stage. The frequency of complications among patients classified as A, B and C were 5.5, 25.3 and 37.1% respectively (p = 0.03). We detected a high frequency of malnutrition in this group of patients. Overall the frequency of postoperative complications was low, however malnourished patients exhibited a higher rate of surgical complications.

    Normative data are presented for Bender test performance, following the system of Koppitz, of 695 Mexican students between 5.0 and 12.1 yr. old (M = 8.7, SD = 2.01) and belonging to different socioeconomic status. The data are compared with the normative group of U.S. students used by Koppitz and with a representative sample of children from Barcelona, Spain. The results indicate that the total number of Bender errors decreased with increasing age of the children and that significant differences existed with respect to socioeconomic status. The comparison of these data with U.S. and Spanish children shows significant differences in all age groups, with the Mexican children scoring lowest. Differences in quality of schooling and in other aspects of education could explain the variability in Bender test performance.

    The recent successful commissioning and operation [1] of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) requires the injection of gold ions of specified energy and intensity with longitudinal and transverse emittances small enough to meet the luminosity requirements of the collider. Ion beams with the desired characteristics are provided by a series of three accelerators, the Tandem, Booster and AGS. The current status and recent performance of these accelerators are reviewed in this paper.

    Increasing the adoption and implementation of evidence-based policies and practices is a key strategy for improving public health. Although there is widespread agreement about the importance of implementing evidence-based public health policies and practices, there are gaps between what has been shown to be effective and what is implemented at the state level. The Centers for Disease Control and Prevention (CDC) developed the Prevention Status Reports (PSRs), a performance measurement system, to highlight evidence-based public health policies and practices and catalyze state performance and quality improvement efforts across the nation. CDC selected a set of 10 topics representing some of the most important public health challenges in the nation. Stakeholders, including state health departments and other partners, helped conceptualize the PSRs and informed the development of the PSR framework, which provides an organizational structure for the system. CDC subject matter experts developed criteria for selecting policies and practices, indicators for each policy and practice, and a criteria-based rating system for each indicator. The PSRs were developed for all 50 states and the District of Columbia. The PSRs were developed and serve as a performance measurement system for monitoring the adoption, reach, and implementation fidelity of evidence-based public health policies and practices nationwide. The PSRs include 33 policy and practice indicators across the 10 health topics. They use a simple 3-level rating system-green, yellow, and red-to report the extent to which each state (and the District of Columbia) has implemented the policy or practice in accordance with supporting evidence or expert recommendations. Results from aggregate analyses show positive change or improvement. The PSRs are a unique part of CDC's work to improve the performance and accountability of the public health system, serving as both a monitoring tool and a call to action to improve health

  3. Motor performance and bodyweight of children and adolescents in Saarland -- status quo.

    2013-01-01

    The motor performance of children and adolescents has been a subject of controversial discussion. As part of a pilot project, 839 schoolchildren from 14 different schools in Saarland were studied and their height, weight and sport motor performance were measured using the German motor performance test DMT 6-18. The results show a slight increase in the number of overweight children compared to reference samples. However, these discrepancies are minor and cannot be judged to be practically relevant because of the weakness of the effects. The average motor test performances of the Saarland schoolchildren were above the average performance of the reference samples in almost all individual performances. There are also hardly any weaker performances in comparison to older studies. The current results for motor performance of Saarland children and adolescents do not, therefore, give any great reason for concern. Further evaluation steps will be needed to clarify the influences that might be associated with adverse characteristics for motor performance (socio-economic status, living situation, leisure behaviour, school performance, etc.).

    The hypothesis that blood biochemical measurements of iron (Fe), copper (Cu), magnesium (Mg) and zinc (Zn) nutritional status and dietary intakes of these minerals are useful predictors of 100-yd free-style swimming performance during actual competition was examined in five female and five male collegiate swimmers. Dietary intakes of Fe, Cu, Mg, and Zn exceeded 70% of daily recommended or estimated safe and adequate intakes. Anemia was not present but body iron stores, assessed with serum ferritin concentration, were reduced in female swimmers who had significantly increased erythrocyte Mg and superoxide dismutase activity which suggest a biochemical adaptation to physical training. Actual 100-yd freestyle times (53.1 +/- 1.4 sec; mean +/- SE) measured during competition were similar to values (52.6 +/- 1.4 sec) predicted with models previously derived from other groups of swimmers. These findings indicate the important role of mineral nutritional status in facilitating the development of peak physical performance and support the hypothesis that mineral element nutritional status is one factor contributing to attainment of optimal human physiological function.

    The purpose of this study was to assess the influence of age, training status, and muscle fiber-type distribution on cycling efficiency. Forty men were recruited into one of four groups: young and old trained cyclists, and young and old untrained individuals. All participants completed an incremental ramp test to measure their peak O2 uptake, maximal heart rate, and maximal minute power output; a submaximal test of cycling gross efficiency (GE) at a series of absolute and relative work rates; and, in trained participants only, a 1-h cycling time trial. Finally, all participants underwent a muscle biopsy of their right vastus lateralis muscle. At relative work rates, a general linear model found significant main effects of age and training status on GE (P 0.05). Power output in the 1-h performance trial was predicted by average O2 uptake and GE, with standardized β-coefficients of 0.94 and 0.34, respectively, although some mathematical coupling is evident. These data demonstrate that muscle fiber type does not affect cycling efficiency and was not influenced by the aging process. Cycling efficiency and the percentage of type I muscle fibers were influenced by training status, but only GE at 120 revolutions/min was seen to predict cycling performance.

    Numerous factors are known to affect the academic performance of students. These include prenatal conditions, birth conditions, postnatal events, nutritional, socio-economic factors and environmental factors. This paper examines the nutritional status and its relationship with academic performance of 9-10 years old primary school children recruited randomly in Selangor, Malaysia. A standard self-administered questionnaire was utilized to obtain pertinent information and a face-to-face interview was also conducted with the parents. Results of the academic performances were extracted from the students' report cards. The intellectual performance was assessed using Raven's Coloured Progressive Matrices. Physical examination was also conducted on these students by doctors. Overall 1,405 students and 1,317 parents responded to the survey. Of these 83.6% were Malays, 11.6% Indians, and 4.2% Chinese. The majority of them (82.9%) were from urban areas. The female: male ratio was 51:49; mean age was 9.71 years. The mean height and weight were 32.3 kg and 135.2 cm respectively. Their mean BMI was 17.42 kg/cm2, with 0.9% underweight, 76.3% normal BMI, 16.3% overweight, and 6.3% obese. Academic performance was significantly correlated with breast feeding, income and educational level of their parents, BMI, and whether they have been taking breakfast. There was a weak correlation between presence of anaemia and intellectual performance. Improving the socio-economic status of the parents will lend a helping hand in the academic performance of the students. Since breast feeding is associated with better academic and intellectual performance it must be emphasized, particularly to expectant mothers in the antenatal clinics.

    Full Text Available Objective: This study aimed to investigate the relationship among motor performance and nutritional status in students. Methods: Attended by 27 adolescents of both sexes, aged between 11-13 years (average 11.74 ± 0.70 years from a private school in Florianópolis/SC. The motor performance was assessed using the MABC-2. For assess the nutritional status was used the BMI calculus. Results: Among 27 participants, 6 had a risk / indicative of motor difficulties and 9 had overweight. The vast majority of participants had adequate height for age. There was negative significant statistically correlation, but moderate, among BMI and total performance in the MABC-2, indicating that as higher the BMI, worse is the motor performance. Conclusion: Based on these results and the literature, it is suggested that in addition to the identification of children with overweight and motor difficulties, programs targeted physical activity and motor interventions are implemented, especially in the school environment, aiming to maintain the health conditions.

    Gender inequality and sexist behaviour is prevalent in almost all workplaces and rampant in online environments. Although there is much research dedicated to understanding sexist behaviour, we have almost no insight into what triggers this behaviour and the individuals that initiate it. Although social constructionist theory argues that sexism is a response towards women entering a male dominated arena, this perspective doesn't explain why only a subset of males behave in this way. We argue that a clearer understanding of sexist behaviour can be gained through an evolutionary perspective that considers evolved differences in intra-sexual competition. We hypothesised that female-initiated disruption of a male hierarchy incites hostile behaviour from poor performing males who stand to lose the most status. To test this hypothesis, we used an online first-person shooter video game that removes signals of dominance but provides information on gender, individual performance, and skill. We show that lower-skilled players were more hostile towards a female-voiced teammate, especially when performing poorly. In contrast, lower-skilled players behaved submissively towards a male-voiced player in the identical scenario. This difference in gender-directed behaviour became more extreme with poorer focal-player performance. We suggest that low-status males increase female-directed hostility to minimize the loss of status as a consequence of hierarchical reconfiguration resulting from the entrance of a woman into the competitive arena. Higher-skilled players, in contrast, were more positive towards a female relative to a male teammate. As higher-skilled players have less to fear from hierarchical reorganization, we argue that these males behave more positively in an attempt to support and garner a female player's attention. Our results provide the clearest picture of inter-sexual competition to date, highlighting the importance of considering an evolutionary perspective when

    Changes in hydration status throughout the day may affect cognitive performance with implications for learning success in the classroom. Our study tested the hypothesis that the benefit of drinking water on working memory and attention depends upon children's hydration status and renal response to water intake. Fifty-two children aged 9-12 years old were tested under two experimental conditions. The treatment session (Water session) consisted of a standard breakfast with 200 ml water, a baseline test, consumption of 750 ml of water over a period of two hours and subsequently retested. No water was provided after breakfast during the control session. Changes in hydration were assessed via urine samples. Cognitive testing consisted of digit span, pair cancellation, and delayed match to sample tasks. Children who exhibited smaller decreases in urine osmolality following water intake performed significantly better on the water day compared to the control day on a digit-span task and pair-cancellation task. Children who exhibited larger decreases in urine osmolality following water intake performed better on the control day compared to the water day on the digit-span task and pair-cancellation task. These results suggest that focusing on adequate hydration over time may be key for cognitive enhancement.

    DOE O 435.1, Radioactive Waste Management, and DOE M 435.1-1, Radioactive Waste Management Manual, require that a determination of continued adequacy of the performance assessment (PA), composite analysis (CA), and disposal authorization statement (DAS) be made on an annual basis, and it must consider the results of data collection and analysis from research, field studies, and monitoring. Annual summaries of low-level waste (LLW) disposal operations must be prepared with respect to the conclusions and recommendations of the PA and CA, and a determination of the need to revise the PA or CA must be made. The annual summary requirement provides a structured approach for demonstrating the continued adequacy of the PA and CA in demonstrating a reasonable expectation that the performance objectives will be met. This annual summary addresses only the status of the Environmental Restoration Disposal Facility (ERDF) PA (CP-60089, Performance Assessment for the Environmental Restoration Disposal Facility, Hanford Site, Washington, formerly WCH-520 Rev. 1)1. The CA for ERDF is supported by DOE/RL-2016-62, Annual Status Report (FY 2016): Composite Analysis of Low Level Waste Disposal in the Central Plateau at the Hanford Site. The ERDF PA portion of the CA document is found in Section 3.1.4, and the ERDF operations portion is found in Section 3.3.3.2 of that document.

Aim: The study aims to estimate the prevalence of psychiatric disorders, and its association with perception of pain and functional status in chronic patients in palliative care. Materials and Methods: The sample was selected via simple randomisation and post consent were assessed using (1 a semi- structured questionnaire to elicit socio-demographic information and medical data (2 Brief Pain Inventory (3 ICD-10 Symptom Checklist (4 ICD-10-Diagnostic Criteria for Research (DCR (5 Montgomery Asberg Depression Rating Scale (MADRS (6 Covi Anxiety Rating Scale (7 Karnofsky Performance Status Scale. Data was analysed using independent sample t test and chi square test. Results: The psychiatric morbidity was 67% with depression and adjustment disorders being the major diagnosis. There was a significant association between psychiatric morbidity pain variables (P = 0.000. Psychiatric morbidity significantly impaired activity, mood, working, walk, sleep, relationship, and enjoyment. There was no association between aetiology of pain, type of cancer, treatment for primary condition and treatment for pain and psychiatric morbidity. The functional status of cancer patients was also poorer in patients with psychiatric morbidity (P = 0.008. Conclusion: There is a high prevalence of psychiatric illness in chronic pain patients of any aetiology. Psychiatric morbidity is associated with increased pain perception, impairment in activity and poor functional status.

    This cross-sectional study was designed to determine whether the academic performance of optometry undergraduates is influenced by enrollment status, learning style or gender. Three hundred and sixty undergraduates in all 3 years of the optometry degree course at Aston University during 2008-2009 were asked for their informed consent to participate in this study. Enrollment status was known from admissions records. An Index of Learning Styles (http://www4.nscu.edu/unity/lockers/users/f/felder/public/Learning-Styles.html) determined learning style preference with respect to four different learning style axes; active-reflective, sensing-intuitive, visual-verbal and sequential-global. The influence of these factors on academic performance was investigated. Two hundred and seventy students agreed to take part (75% of the cohort). 63% of the sample was female. There were 213 home non-graduates (entrants from the UK or European Union without a bachelor's degree or higher), 14 home graduates (entrants from the UK or European Union with a bachelor's degree or higher), 28 international non-graduates (entrants from outside the UK or European Union without a bachelor's degree or higher) and 15 international graduates (entrants from outside the UK or European Union with a bachelor's degree or higher). The majority of students were balanced learners (between 48% and 64% across four learning style axes). Any preferences were towards active, sensing, visual and sequential learning styles. Of the factors investigated in this study, learning styles were influenced by gender; females expressed a disproportionate preference for the reflective and visual learning styles. Academic performance was influenced by enrollment status; international graduates (95% confidence limits: 64-72%) outperformed all other student groups (home non graduates, 60-62%; international non graduates, 55-63%) apart from home graduates (57-69%). Our research has shown that the majority of optometry students

    It is now well accepted that theory of mind (ToM) functioning is impaired in Parkinson's disease (PD) patients. However, what remain unknown are the functions that underlie this impairment. It has been suggested that cognitive skills may be key in this area of functioning; however, many of the cognitive tests used to assess this have relied on intact visuospatial abilities. This study aimed to examine whether deficits in ToM were generated by cognitive or visuospatial dysfunction and the mediating effect of visuospatial function on ToM performance. Fifty PD patients (31 male, 19 female; mean age = 66.34 years) and 49 healthy controls (16 male, 33 female; mean age = 67.29 years) completed a ToM task (reading the mind in the eyes) and visuospatial task (line orientation). The results revealed that current cognitive status was a significant predictor for performance on the ToM task, and that 54% of the total effect of cognitive status on ToM was mediated by visuospatial abilities. It was concluded that visuospatial functioning plays an important mediating role for the relationship between executive dysfunction and affective ToM deficits in PD patients, and that visuospatial deficits may directly contribute to the presence of affective ToM difficulties seen in individuals with PD.

    Full Text Available The purpose of the study was to evaluate the developmental changes in performance in a repeated-sprint ability (RSA test in young soccer players of contrasting maturity status. A total of 83 regional level Portuguese youth soccer players, aged 11- 13 years at baseline was assessed annually. Stature, body mass, 7x34.2-m sprint protocol (25-s active recovery, 20-m multi-stage continuous shuttle endurance run and counter-movement jump (CMJ without the use of the arms were measured. Fat-free mass (FFM was determined by age and gender- specific formulas. Developmental changes in total sprint time across ages were predicted using multilevel modeling. Corresponding measurements were performed on an independent cross-sectional subsample of 52 youth soccer players 11-17 years to evaluate the predictive model. CA, CA2, maturational status (SA-CA, body size (mass and stature, FFM, aerobic endurance, lower limb explosive strength and annual volume training significantly improved the statistical fit of the RSA multilevel model. In 'late' maturing athletes, the best model for predicting change in RSA was expressed by the following equation: 86.54 - 2.87 x CA + 0.05 x CA2 - 0.25 x FFM + 0.15 x body mass + 0.05 x stature - 0.05 x aerobic endurance - 0.09 x lower limb explosive strength - 0.01 x annual volume training. The best fitting models for players who were 'on time' and 'early' maturing were identical to the best model for late maturing players, less 0.64 seconds and 1.74 seconds, respectively. Multilevel modeling provided performance curves that permitted the prediction of individual RSA performance across adolescent years in regional level soccer players

    Full Text Available Abstract Background Little work has been done to investigate the suggestion that the use of selected scales from a multi-scale health-status questionnaire would compromise reliability and validity. The aim of this study was to compare the performance of three scales selected from the SF-36 generic health questionnaire when administered in isolation or within the entire SF-36 to patients with musculoskeletal disorders. Methods Two groups of patients referred to an orthopedic department completed a mailed questionnaire within 4 weeks prior to and a second questionnaire during their visit. The first group completed three SF-36 scales related to physical health (physical functioning, bodily pain, and general health perceptions on one occasion and all eight SF-36 scales on the other occasion. The second group completed the entire SF-36 on two occasions. Results for patients who reported unchanged health status and had complete scores were analyzed; 80 patients in the first and 62 patients in the second group. Results The Cronbach alpha reliability and intraclass correlation coefficients exceeded 0.7 for all three scales for both groups. For the first group the mean difference between the scores was 0.4 point for physical functioning, 2.5 points for bodily pain, and 0.5 point for general health perceptions, which did not differ significantly from the corresponding differences for the second group (0.1, 1.9 and 1 point, respectively. Conclusion The use of selected scales from a multi-scale health-status questionnaire seems to yield similar results compared to their use within the entire questionnaire.

    Full Text Available Objective: to investigate the association between nutritional status and functional limitation and disability in an elderly population in southern Brazil. Methods: epidemiological, cross-sectional household-based study carried out with 477 elderly of both sexes (60 to 100 years. Body mass index (BMI served to assess the nutritional status: underweight (BMI 27 kg/m2. The sum score (0-5 obtained in three tests: "chair stand" and "pick up a pen" (measured by time and standing balance (four static measurements assessed the functional limitation. The disability was evaluated by the difficulty in performing one or more self-reported tasks related to basic activities of daily living (ADLs and instrumental activities of daily living (IADLs. Crude and adjusted analyzes (3 models were carried out using Poisson regression; prevalence ratios (PR and 95% confidence intervals (CI were calculated. Results: crude analyzes showed a positive association between underweight and functional limitation (PR = 2.71, 95% CI = 1.63 to 4.51; overweight and disability in ADLs (PR = 2.20, CI 95% = 1.44 to 3.35; overweight and disability in IADLs (PR = 1.56, CI 95% = 1.20 to 2.03. The additional adjustments for gender, age, level of education, living arrangements, current work, cognitive function and number of morbidities reduced the strength of the associations, without changing the statistical strength. Conclusion: nutritional status is a factor that is independently and positively associated with functional limitation and disability. We recommend the use of this indicator to monitor the health of the elderly.

    Full Text Available The present paper describes a live project study carried out for the universities located in the western Himalayan region of India in the year 2009. The objective of this study is to undertake the task of assessment regarding initiative, utilization of ICT resources, its performance and impact in these higher educational institutions/universities. In order to answer these, initially basic four- tier framework was prepared. Followed by a questionnaire containing different ICT components 18 different groups like vision, planning, implementation, ICT infrastructure and related activities exhibiting performance. Primary data in the form of feedback on the five point scale, of the questionnaire, was gathered from six universities of the region. A simple statistical analysis was undertaken using weighted mean, to assess the ICT initiative, status and performance of various universities. In the process, a question related to Performance Indicator was identified from each group, whose Coefficient of Correlation was calculated. This study suggests that a progressive vision, planning and initiative regarding academic syllabi, ICT infrastructure, used in training the skilled human resource, is going to have a favourable impact through actual placement, research and play a dominant role at the National and International level.

The results indicated that the variable "work status" features second last on the list of nine successful variables for predicting academic performance. Generally, it would appear that the employment practice for technikon students is not as important a requirement for academic success as the co-operative education philosophy would like it to be.

Body weight and feed intake were recorded on d0, 14 and 56 of the trial. Ten piglets from each group were selected and blood collected by anterior vena cava puncture at 0, 14 and 56 d for reactive oxygen metabolite (ROMs determination. HV showed final weight higher than the other groups (P<0.05, and oxidative stability was improved by both integrations of verbascoside. These results support the view that Verbascoside influences the growth performances and oxidative status of piglets.

    The Large Binocular Telescope Interferometer is a NASA-funded nulling and imaging instrument designed to coherently combine the two 8.4-m primary mirrors of the LBT for high-sensitivity, high-contrast, and high-resolution infrared imaging (1.5-13 micrometer). PHASECam is LBTI's near-infrared camera used to measure tip-tilt and phase variations between the two AO-corrected apertures and provide high-angular resolution observations. We report on the status of the system and describe its on-sky performance measured during the first semester of 2014. With a spatial resolution equivalent to that of a 22.8-meter telescope and the light-gathering power of single 11.8-meter mirror, the co-phased LBT can be considered to be a forerunner of the next-generation extremely large telescopes (ELT).

    Full Text Available Over the last decades, the emphasis on the health of dairy cows has changed from an individual to a herd level. In this scenario, the role played by the recording system and its interpretation by veterinarians has gained primordial importance. The records of productive and reproductive performance and of sanitary status from a southern Brazilian dairy cattle herd have been presented and discussed. The period of study was 2000-2009. Mean values per lactation period were 349D 8436M 290F 275P 201SCS (D: days in lactation, M: kg of milk yield, F: kg of fat, P: kg of protein and SCS: somatic cell score in 1000 cells/ml of milk. Major indexes of reproductive efficiency included age at first calving (31 months, services per conception (2.1, intercalving interval (428 days, calving to conception interval (146 days, mean annual rates of parturitions (76.2%, fetal losses (9.8-19.0%, and stillbirths (3.6%, apart of voluntary waiting period (94 days. Main information on sanitary status of the herd was associated with the mean prevalence of common disorders of dairy cattle such as anaplasmosis (29.8%, mastitis (27.8%, digital diseases (26.3%, ovarian cysts (21.3%, placental retention (19.7%, postpartum uterine infections (10.6%, and calf diarrhea (23.7% and pneumonia (16.8%, among others. In addition, culling reasons (low reproductive performance [56.3%] and udder/mastitis problems [33.6%], causes of cattle deaths (anaplasmosis [16.4%] and leukosis [11.4], and the impact of cattle diseases such as tuberculosis, leukosis, and neosporosis on the herd have also been presented and succinctly discussed.

    Background and objective Pemetrexed have been approved for the treatment of patients affected by advanced non-small cell lung cancner (NSCLC) in progression after first-line chemotherapy. We evaluated the activity and feasibility of pemetrexed in previously treated NSCLC.Methods Patients with histologically or cytologically confirmed NSCLC were evaluated from April 2007 to March 2009. The patients had relapsed or progressed after prior chemotherapy treatment. Pemetrexed (500 mg/m2) was administered intravenously once every 3 weeks after progression to prior chemotherapy. The tumor response was evaluated according to RECIST criteria by chest CT at every 2 cycles of chemotherapy.Results A total 61 patients were eligible for analysis. Performance status of them (100%) was over 2. The response rate and disease control rate were 14.7% and 37.7% respectively. Non-squamous cell carcinoma histology was significantly associated with a superior response rate (P=0.045) and disease control rate (P=0.008). The median survival time and the median progression free survival (PFS) time were 6.11 months and 2.17 months, respectively. Comparing the efficacy of pemetrexed in these two settings [second-line versus (12/61) more than third (49/61)], there was no significant difference in regard to median survival (11.18 months vs 11.46 months, P=0.922,S), but PFS was more longer in third- or further-line groups than second-line group (1.39 months vs 2.25 months, P=0.015,3).Conclusion Pemetrexed is a feasible regimen in previously treated NSCLC with poor performance status.

    To investigate the impact of nutritional status on self-reported as well as performance-based indicators of physical function in a rural elderly population in Bangladesh. A cross-sectional study conducted in Matlab, Bangladesh, included 457 randomly selected community-living elderly persons aged 60 years or more (60-92 years; 69 +/- 7 years). Mobility, activities of daily living (ADL), performance tests, handgrip strength, the Mini Nutritional Assessment (MNA) and a structured questionnaire were used to assess physical function, nutritional status, socioeconomic status and health status, respectively. Descriptive and linear hierarchical regression analyses were applied. Seven per cent of the participants reported limitations in mobility, and 8% reported limitations in ADL. However, more than half of the participants had difficulties in performing one or more items in the performance tests. According to the MNA, 26% of the participants were undernourished and 62% were at risk of malnutrition. More undernourished participants than well-nourished participants reported limited mobility, impaired ADL and difficulties in the performance tests. A corresponding reduction in grip strength was observed in the undernourished group. Accordingly, higher MNA scores, indicating better nutritional status, were significantly associated with higher mobility index, higher ADL index, higher performance tests index, and higher scores in handgrip strength. These associations remained after adjusting for demographic, socioeconomic and health status differences. Good nutritional status is important for the physical function of elderly people, even after controlling for possible confounders. Performance tests indicated a higher degree of functional impairment than that observed by self-reported estimation.

    2016-09-01

    We studied the effect of audiovisual stimulation training course on physical development, functional state of the cardiovascular system, blood biochemical parameters, and hormonal status of athletes. The training course led to improvement of physical performance and adaptive capacities of the circulatory system, increase in plasma levels of total protein, albumin, and glucose and total antioxidant activity, and decrease in triglyceride, lipase, total bilirubin, calcium, and phosphorus. The concentration of hormones (cortisol, thyrotropin, triiodothyronine, and thyroxine) also decreased under these conditions. In the control group, an increase in the concentration of creatinine and uric acid and a tendency toward elevation of lowdensity lipoproteins and total antioxidant activity were observed in the absence of changes in cardiac function and physical performance; calcium and phosphorus concentrations reduced. The improvement in functional state in athletes was mainly associated with intensification of anabolic processes and suppression of catabolic reactions after audiovisual stimulation (in comparison with the control). Stimulation was followed by an increase in the number of correlations between biochemical and hormonal changes and physical performance of athletes, which attested to better integration of processes at the intersystem level.

    Malnutrition disorders affect more than 30% of schoolchildren in Egypt. This problem appears to be largely attributable to poor dietary quality and micronutrient deficiencies, such as iron and vitamin A. Inadequate nutrition intake has important implications because malnutrition has been shown to negatively affect the cognitive development of primary schoolchildren. This study assesses the awareness of schoolteachers about the impact of malnutrition on the scholastic performance of primary schoolchildren living in Egypt. Two focus group discussions were conducted with Egyptian schoolteachers from the Quena and Kharbia Governorates. The study indicates that schoolteachers consider low body weight and thinness as the primary signs of malnutrition. They do not prioritize malnutrition as a factor for poor scholastic performance. They also suggest that unhealthful eating habits, especially a lack of breakfast, negatively affect children's interaction with schoolteachers and their ability to excel in their studies. Schoolteachers endorse a more reliable and nutritionally valuable school-feeding program as a way to increase the scholastic performance of their students. The teachers advocate developing integrated programs between the Ministry of Education, the Ministry of Health and Population, teachers, children, and parents that provide nutrition education. A lack of awareness among teachers about the relationship of nutrition and cognitive function can lead to the misdiagnosis or delayed management of malnourished and scholastically challenged schoolchildren. This paper suggests that proper school-feeding programs and nutrition education programs, which integrate government ministries, teachers, children and parents, should be developed to improve the physical and cognitive health status of Egyptian schoolchildren.

    Full Text Available Excessive physical exercise overproduces reactive oxygen species. Even if elite sportsmen increase their antioxidant status by regular physical training, during the competition period, this improvement is not sufficient to limit free radical production which could be detrimental to the body. The aim of this randomized, double-blind, placebo controlled, and crossover study on 20 elite sportsmen (handball = 10, basketball = 5, sprint = 4, and volleyball = 1 during the competition period was to determine if the consumption of a grape extract (GE; Vitis vinifera L. was able to improve the parameters related to (i anti-oxidative status and oxidative stress and (ii physical performance. Specific biomarkers of antioxidant capacity, oxidative stress, skeletal cell muscle damage, and other general biomarkers were determined in plasma and urine before (D0 and after one month (D30 of placebo or GE supplementation (400mg·d-1. Effort tests were conducted using the Optojump® system, which allows determining the total physical performance (EnRJ45, explosive power (RJ110, and fatigue (RJL5. The plasma ORAC value was not modified in the placebo group; however, GE increased the ORAC value compared to the placebo at D30 (14 966+/-335 vs 14 242+/-339 µmol Teq·L-1; p < 0.05. The plasma FRAP value was significantly reduced in the placebo group, but not in the GE group. Therefore, GE limited the reduction of FRAP compared to the placebo at D30 (1 053.7+/-31.5 vs 993.7+/-26.7 µmol Teq·L-1; p < 0.05. Urinary isoprostane values were increased in the placebo group, but were not modified in the GE group. Consequently, GE limited the production of isoprostanes compared to the placebo at D30 (1.24+/-0.12 vs 1.26+/-0.13 ng·mg-1 creatinine; p < 0.05. GE administration, compared to the placebo at D30, reduced the plasmatic creatine phosphokinase concentration (CPK, 695.7+/-177.0 vs 480.0+/-81.1 IU·L-1, p = 0.1 and increased hemoglobin levels (Hb, 14.5+/-0.2 vs 14

    The study examines the question to what extent children and adolescents differ in terms of motor performance in dependence of their socio-economic status (SES). A sample of 1389 students in Saarland (Germany) in various grades (1st grade: age 7.26 ± 0.38 years, 4th grade: 10.3 ± 0.4 years, 7th grade: 13.44 ± 0.49 years, 10th grade: 16.36 ± 0.69 years) has been examined. Their motor performance has been measured by means of 20-m sprint, standing long jump and a 6-minute run, and the SES by means of a parent survey. Based on the indicators school education, professional education, job position and household income, the SES was categorised in a three-step approach (low, middle, high). The influence on dependent variables was analysed by using multivariate analysis of variance. Students with a higher SES exhibit a higher motor performance compared with that of lower SES (results of the multivariate: Pillai's Trace = .05, F[6; 2526] = 12.56, p = .001; [Formula: see text]). In addition, the data for students of higher SES differ significantly from the data of a German reference sample (higher motor performance compared with standard values). In contrast, persons of lower SES do not differ from the reference sample, and those of middle SES differ only slightly from the reference sample. The results are relevant when considering specific prevention efforts concerning motor performance of certain groups. Especially those institutions and schools should be focused upon whose catchment area includes a high share of socially disadvantaged population groups.

    Hebecker, Dustin [HU-Berlin (Germany); DESY (Germany)

    2016-07-01

    The Wavelength-shifting Optical Module is a single-photon sensor that employs wavelength-shifting and light-guiding techniques to maximize the collection area while minimizing the dark noise rate. The sensor is tailored towards application in ice-Cherenkov neutrino detectors, such as IceCube-Gen2 or MICA. It is aimed at decreasing the energy threshold as well as increasing the energy resolution and the vetoing capability of the neutrino telescope, when compared to a setup with optical sensors similar to those used in IceCube. The proposed sensor captures photons with wavelengths between 250 nm and 400 nm. These photons are re-emitted with wavelengths above 400 nm by a wavelength shifter coating applied to a 90 mm diameter polymer tube. This tube guides the light towards a small-diameter PMT via total internal reflection. As a core component the wavelength shifting and light guiding inner tubes performance has been investigated with multiple methods that are presented. Furthermore the status of the whole prototype development and its performance are discussed.

    Several studies in recent years have indicated a link between socio-economic status (SES) of families and children's language development, including studies that have measured children's language through formal standardized test procedures. High numbers of children with low performance have been found in lower socio-economic groups in some studies. This has proved a cause for concern for both clinicians and educationalists. To investigate the relationship between maternal education and postcode-related indicators of SES, and children's performance on the New Reynell Developmental Scales (NRDLS). Participants were 1266 children aged between 2;00 and 7;06 years who were recruited for the standardization of a new assessment procedure (NRDLS). Children were divided into four groups reflecting years of maternal education, and five groups reflecting SES Index of Multiple Deprivation (IMD) quintiles for the location of participating schools and nurseries. Groups were compared using analysis of covariance (ANCOVA), with age as a covariate, in order to identify which might be affected by the two SES variables. Where relationships were found between SES and performance on the scales, individual children's standard scores were looked at to determine numbers potentially at risk for language delay. An effect of years of maternal education on performance was found such that children whose mothers had minimum years performed less well than other children in the study, this effect being stronger for younger children. Children attending schools or nurseries in IMD quintile 1 areas performed less well in language production. Higher than expected numbers with language delay were found for younger children whose mothers had minimum years of education, and for children in quintile 1 schools and nurseries; however, numbers were not as high as noted in some other studies. Characteristics of the participant sample and measures used for language and SES may explain these results and are

    Little information is available regarding the effects of vitamin D and its metabolites on reproduction in swine. To investigate the effects of feeding the circulating metabolite of vitamin D, 25-hydroxycholecalciferol (25OHD3, ROVIMIX Hy • D, DSM Nutritional Products, Basel, Switzerland) on maternal and fetal circulating 25OHD3 concentration and gilt reproductive performance, a total of 40 PIC Camborough-22 gilts (BW on d -6 = 138 kg) in 4 replicates were randomly assigned to 1 of 2 corn-soybean meal-based diets. The control diet (CTL) was formulated to contain 2,500 IU D3/kg diet, and the experimental diet (25OHD3) was formulated to contain 500 IU D3/kg diet + 50 μg 25OHD3/kg diet. Gilts were fed 2.7 kg of their assigned diet once daily beginning 43 d before breeding. Gilt BW were measured on gestational d -6 and d 90. Gilts were artificially inseminated with PIC 337-G semen 12 h and 24 h after showing signs of estrus. Blood samples were collected from the jugular vein on gestational d -43, -13, 46, and 89 for analysis of circulating 25OHD3 plasma concentration and overall vitamin D status of the gilts. At gestational d 90 ± 1, gilts were harvested and reproductive tracts were removed. Fetal weight, sex, crown-to-rump length (CRL), as well as the number of mummified fetuses were recorded. As expected, circulating plasma concentrations of 25OHD3 were not different among treatment groups at d -43 (CTL = 53.8 ng/mL, 25OHD3 = 57.4 ng/mL; P = 0.66). However, gilts fed 25OHD3 had greater (P 0.05). However, litter size was larger (CTL = 10.2; 25OHD3 = 12.7; P = 0.04) in 25OHD3-fed gilts compared with CTL-fed gilts. Notably, mean fetal weight was not decreased in 25OHD3-fed gilts as frequently occurs when litter size is increased. Overall, feeding 25OHD3 to first-service gilts before and during gestation improved both maternal and fetal vitamin D status and improved maternal reproductive performance.

    Palliative radiotherapy (RT) is routinely used in end of life care of patients with advanced malignancies; however, unnecessarily burdensome treatment shortly before death should be avoided. There is little knowledge on incidence and causes of intercurrent deaths during palliative RT. In this study death events among inpatients receiving palliative RT between January 2009 and December 2011 at this department were retrospectively analyzed. Among epidemiological factors, treatment schedule and chronology, latency and duration of treatment in relation to the actual survival were identified. In this study 52 patients died during or shortly after palliative RT. Symptomatic bone metastases and brain metastases represented the most common RT indications. The general health status was poor with a median Karnofsky performance score of 50 %, RT was realized with a median single dose of 2.5 Gy to a median total dose of 30.5 Gy and was stopped prematurely in 73 % of patients. On average 53 % of the remaining lifetime was occupied by latency to starting RT. Once RT was begun the treatment duration required a median 64 % of the still remaining lifetime. The majority of patients who died had explicitly adverse pre-existing factors and rarely completed RT as scheduled. Latency to RT and RT duration occupied more than half of the remaining lifetime.

    Scoping simulations performed using a severe accident code can be applied to investigate the influence of advanced materials on beyond design basis accident progression and to identify any existing code limitations. In 2012 an effort was initiated to develop a numerical capability for understanding the potential safety advantages that might be realized during severe accident conditions by replacing Zircaloy components in light water reactors (LWRs) with silicon carbide (SiC) components. To this end, a version of the MELCOR code, under development at the Sandia National Laboratories in New Mexico (SNL/NM), was modified by replacing Zircaloy for SiC in the MELCOR reactor core oxidation and material properties routines. The modified version of MELCOR was benchmarked against available experimental data to ensure that present SiC oxidation theory in air and steam were correctly implemented in the code. Additional modifications have been implemented in the code in 2013 to improve the specificity in defining components fabricated from non-standard materials. An overview of these modifications and the status of their implementation are summarized below.

    The CALorimetric Electron Telescope (CALET) space experiment, currently under development by Japan in collaboration with Italy and the United States, will measure the flux of cosmic-ray electrons (including positrons) to 20 TeV, gamma rays to 10 TeV and nuclei with Z=1 to 40 up to 1,000 TeV during a two-year mission on the International Space Station (ISS), extendable to five years. These measurements are essential to search for dark matter signatures, investigate the mechanism of cosmic-ray acceleration and propagation in the Galaxy and discover possible astrophysical sources of high-energy electrons nearby the Earth. The instrument consists of two layers of segmented plastic scintillators for the cosmic-ray charge identification (CHD), a 3 radiation length thick tungsten-scintillating fiber imaging calorimeter (IMC) and a 27 radiation length thick lead-tungstate calorimeter (TASC). CALET has sufficient depth, imaging capabilities and excellent energy resolution to allow for a clear separation between hadrons and electrons and between charged particles and gamma rays. The instrument will be launched to the ISS within 2014 Japanese Fiscal Year (by the end of March 2015) and installed on the Japanese Experiment Module-Exposed Facility (JEM-EF). In this paper, we will review the status and main science goals of the mission and describe the instrument configuration and performance.

    Full Text Available Introduction: The prognosis of advanced gastric cancer patients, especially those with poor performance status (PS, is generally dismally poor. Patients with PS 3–4 are usually ineligible for participation in clinical studies and are managed with only best supportive care. Case Report: A 63-year-old male with advanced gastric cancer was admitted to our hospital. His PS was markedly impaired (Eastern Cooperative Oncology Group PS 4, with dyspnea secondary to lymphangitis, pleuritis and pericarditis. He also had bilateral leg paralysis due to multiple bone metastases. He was treated with chemotherapy using 5-fluorouracil and leucovorin for 14 days with pericardial drainage followed by intrapericardial infusion of cisplatin. He was also treated with radiotherapy for bone metastasis. The patient required 5 l/min oxygen therapy at the start of chemotherapy, but his dyspnea was improved by day 14 and he no longer required supplemental oxygen therapy. His leg paralysis also improved with the radiation therapy. His PS was significantly improved with this multimodal treatment modality, and he was ultimately discharged with chemotherapy with oral fluoropyrimidine. Conclusion: This case suggests that multimodal therapy including chemotherapy may be beneficial in advanced gastric cancer patients even in the setting of poor PS. Further study might be required to confirm the benefit of chemotherapy in this patient population.

    We examined temporal synchronization in joint music performance to determine how social status, auditory feedback, and animacy influence interpersonal coordination. A partner's coordination can be bidirectional (partners adapt to the actions of one another) or unidirectional (one partner adapts). According to the dynamical systems framework, bidirectional coordination should be the optimal (preferred) state during live performance. To test this, 24 skilled pianists each performed with a confederate while their coordination was measured by the asynchrony in their tone onsets. To promote social balance, half of the participants were told the confederate was a fellow participant - an equal social status. To promote social imbalance, the other half was told the confederate was an experimenter - an unequal social status. In all conditions, the confederate's arm and finger movements were occluded from the participant's view to allow manipulation of animacy of the confederate's performances (live or recorded). Unbeknownst to the participants, half of the confederate's performances were replaced with pre-recordings, forcing the participant into unidirectional coordination during performance. The other half of the confederate's performances were live, which permitted bidirectional coordination between performers. In a final manipulation, both performers heard the auditory feedback from one or both of the performers' parts removed at unpredictable times to disrupt their performance. Consistently larger asynchronies were observed in performances of unidirectional (recorded) than bidirectional (live) performances across all conditions. Participants who were told the confederate was an experimenter reported their synchrony as more successful than when the partner was introduced as a fellow participant. Finally, asynchronies increased as auditory feedback was removed; removal of the confederate's part hurt coordination more than removal of the participant's part in live

    Because poor performance status (PS) is an independent prognostic factor in non-small cell lung cancer (NSCLC), PS scores are widely used by oncologists to make treatment decisions. Advanced NSCLC patients with an Eastern Cooperative Oncology Group PS of 2 have poor prognoses and are frequently excluded from clinical trials. This article reviews the efficacy and safety of pemetrexed in this patient group. We identified English-language literature (through March 2015) involving completed and ongoing studies through searches of PubMed, meeting abstracts, ClinicalTrials.gov and the European Clinical Trials Register; search terms included 'pemetrexed,' 'NSCLC' and 'PS2'. Only studies reporting ≥1 subset analysis of PS2 patients receiving pemetrexed were chosen. Our search identified a total of ten pemetrexed studies in PS2 patients. Eight studies included only chemonaive patients, one study included both chemonaive patients and patients with one prior chemotherapy regimen and one study included only patients with one prior regimen. In subset analyses in these studies, PS2 patients had worse outcomes than PS0-1 patients regardless of treatment. In a phase 3 study, chemonaive advanced NSCLC patients with PS2 receiving pemetrexed‑carboplatin versus pemetrexed experienced improved overall survival [hazard ratio (HR)=0.62; P=0.001], progression-free survival (HR=0.46; Pstudies, PS2 patients treated with pemetrexed plus carboplatin as first-line therapy had improved response rates and survival. Additional research on PS2 patients is needed.

  14. Iron and the female athlete: a review of dietary treatment methods for improving iron status and exercise performance.

    2015-01-01

    Iron is a functional component of oxygen transport and energy production in humans and therefore is a critically important micronutrient for sport and exercise performance. Athletes, particularly female athletes participating in endurance sport, are at increased risk of compromised iron status due to heightened iron losses through menstruation and exercise-induced mechanisms associated with endurance activity. Conventionally oral iron supplementation is used in prevention or/and treatment of iron deficiency. However, this approach has been criticised because of the side effects and increased risk of iron toxicity associated with the use of supplements. Thus, more recently there has been a growing interest in using dietary modification rather than the use of supplements to improve iron status of athletes. Dietary iron treatment methods include the prescription of an iron-rich diet, or/and haem iron-based diet, dietary advice counselling and inclusion of novel iron-rich products into the daily diet. Although studies using dietary modification are still scarce, current literature suggests that dietary iron interventions can assist in maintaining iron status in female athletes, especially during intensive training and competition. Future research should focus on the most efficient method(s) of dietary modification for improvement of iron status and whether these approaches can have a favourable impact on sports and exercise performance.

    Presently, there is no recommendation on how to assess functional status of chronic obstructive pulmonary disease (COPD) patients. This study aimed to summarize and systematically evaluate these measures.Studies on measures of COPD patients' functional status published before the end of January 2015 were included using a search filters in PubMed and Web of Science, screening reference lists of all included studies, and cross-checking against some relevant reviews. After title, abstract, and main text screening, the remaining was appraised using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) 4-point checklist. All measures from these studies were rated according to best-evidence synthesis and the best-rated measures were selected.A total of 6447 records were found and 102 studies were reviewed, suggesting 44 performance-based measures and 14 patient-reported measures. The majority of the studies focused on internal consistency, reliability, and hypothesis testing, but only 21% of them employed good or excellent methodology. Their common weaknesses include lack of checks for unidimensionality, inadequate sample sizes, no prior hypotheses, and improper methods. On average, patient-reported measures perform better than performance-based measures. The best-rated patient-reported measures are functional performance inventory (FPI), functional performance inventory short form (FPI-SF), living with COPD questionnaire (LCOPD), COPD activity rating scale (CARS), University of Cincinnati dyspnea questionnaire (UCDQ), shortness of breath with daily activities (SOBDA), and short-form pulmonary functional status scale (PFSS-11), and the best-rated performance-based measures are exercise testing: 6-minute walk test (6MWT), endurance treadmill test, and usual 4-meter gait speed (usual 4MGS).Further research is needed to evaluate the reliability and validity of performance-based measures since present studies failed to provide convincing

To date, the information regarding the association between nutritional status and physical performance does not provide a complete picture. Most studies used limited or self-reported measures to evaluate physical performance. The objective of this study was to examine the correlation between nutritional status and comprehensive physical performance measures among undernourished older adults who reside in residential institutions.Methods: Forty-seven older adults (26 males, 21 females aged ≥60 (69.23±8.63 years who were identified as undernourished from two residential institutions participated in this study. A battery of physical performance tests (10 m gait speed test, dominant hand grip strength test, timed five-repetition sit-to-stand test, ten step test, arm curl test, scratch test, and respiratory muscle strength test, biochemical profiles (serum albumin, hemoglobin, serum ferritin, and prealbumin levels, and falls risk using the short-form Physiological Profile Approach were performed. The Functional Ability Questionnaire and Geriatric Depression Scale were also administered.Results: The results demonstrated that generally older adults with undernourishment scored poorly on the physical performance tests, had depression, and a high risk of falls.

    Conclusions: The majority of participants were willing to share their HIV status. False-negative reports were largely explained by lack of testing, suggesting HIV stigma is retreating in this setting, and that expansion of HIV testing and retesting is still needed in this population. In HIV interventions where testing is not possible, self-reported status should be considered as a routine first step to establish HIV status.

    The polymorphic variation in the val158met position of the catechol-O-methyltransferase (COMT) gene is associated with differences in executive performance, processing speed, and attention. The purpose of this study is: (1) replicate previous COMT val158met findings on cognitive performance; (2) determine whether COMT val158met effects extend to a real-world task, aircraft navigation performance in a flight simulator; and (3) determine if aviation expertise moderates any effect of COMT val158met status on flight simulator performance. One hundred seventy two pilots aged 41-69 years, who varied in level of aviation training and experience, completed flight simulator, cognitive, and genetic assessments. Results indicate that although no COMT effect was found for an overall measure of flight performance, a positive effect of the met allele was detected for two aspects of cognitive ability: executive functioning and working memory performance. Pilots with the met/met genotype benefited more from increased levels of expertise than other participants on a traffic avoidance measure, which is a component of flight simulator performance. These preliminary results indicate that COMT val158met polymorphic variation can affect a real-world task.

    A link between low parental socioeconomic status and mental health problems in offspring is well established in previous research. The mechanisms that explain this link are largely unknown. The present study investigated whether school performance was a mediating and/or moderating factor in the path between parental socioeconomic status and the risk of hospital admission for non-fatal suicidal behaviour. A national cohort of 447 929 children born during 1973-1977 was followed prospectively in the National Patient Discharge Register from the end of their ninth and final year of compulsory school until 2001. Multivariate Cox proportional hazards and linear regression analyses were performed to test whether the association between parental socioeconomic status and non-fatal suicidal behaviour was mediated or moderated by school performance. The results of a series of multiple regression analyses, adjusted for demographic variables, revealed that school performance was as an important mediator in the relationship between parental socioeconomic status and risk of non-fatal suicidal behaviour, accounting for 60% of the variance. The hypothesized moderation of parental socioeconomic status-non-fatal suicidal behaviour relationship by school performance was not supported. School performance is an important mediator through which parental socioeconomic status translates into a risk for non-fatal suicidal behaviour. Prevention efforts aimed to reduce socioeconomic inequalities in non-fatal suicidal behaviour among young people will need to consider socioeconomic inequalities in school performance.

    Falls are a leading cause of fatal and nonfatal injuries among the elderly. Accurate determination of risk factors associated with falls in older adults is necessary, not only for individual patient management, but also for the development of fall prevention programs. The purpose of this study was to evaluate the effectiveness of clinical measures, such as the one-legged stance test (OLST), sit-to-stand test (STST), manual muscle tests (MMT), and response speed in predicting faller status in community-dwelling older adults (N = 94, age 60-89 years). The variables assessed were single-leg standing (as measured by OLST), STST, and MMT of 12 different muscle groups (hip flexors, hip abductors, hip adductors, knee flexors, knee extensors, ankle dorsiflexors, ankle plantarflexors, shoulder flexors, shoulder abductors, elbow flexors, elbow extensors, and finger flexors), and speed of response (as measured by a visual hand reaction and movement time task). Of the 94 older adults assessed, 28 (29.7%) reported at least one fall within the previous year. The discriminant analysis revealed that there were six variables that significantly discriminated between fallers and nonfallers. These variables included MMT of the ankle dorsiflexors, knee flexors, hip abductors, and knee extensors, as well as time on the OLST and the STST. The results indicate that simple clinical measures of musculoskeletal function can discriminate fallers from nonfallers in community-dwelling older adults.

    Using a factorial design: two full floor types, concrete vs. concrete waterproofed with resin (resin floor) and two slat types, concrete vs. metal, were used to house 72 pigs in four rooms (18 pigs room-1). During the experimental period which lasted from 22.9 kg to 112.7 kg live weight the four groups of pigs received the same feed. Growth, water consumption and health status of the pigs as well as subjective odour level inside the rooms were studied. The resin floor with metal slats tended (P < 0.1) to improve feed conversion efficiency and positively affected (P < 0.03) pig health. In the room with the resin floor and metal slats odour level was significantly lower than in the other three rooms. The potential predictive function for the relationship between average daily water consumption (WC, in L) and feed average daily intake (FADI, in kg) is WC = 2.692 x FADI{sup 1}.265. Odour level increased with pig live weight. The use of resin as an impermeable floor material is promising for housing growing, finishing pigs. (Author)

  17. Do small differences in hydration status affect mood and mental performance?

    Benton, David; Young, Hayley A

    2015-09-01

    Although it has been suggested that many in the general population are dehydrated to the extent that mood and cognition are disrupted, there has been little research investigating mild levels of dehydration. When dehydration reduces body mass by more than 2%, it has been consistently reported that mood is influenced, fatigue is greater, and alertness is lower. In contrast, the effects on cognition have been less consistent. Only a few studies have looked at females and these studies made little attempt to consider hormones that influence kidney functioning. In particular, there has been virtually no attempt to look at changes in hydration status in the range that occurs in individuals with a sedentary lifestyle in a temperate climate. There is a consequent need to study individuals who have lost up to 1% of body mass due to dehydration. While 4 intervention trials have found that the cognition of children improved in response to water consumption, the effects of water consumption on cognition in older adults, another high-risk group, have been largely ignored.

    The effects of land management and disturbance on ecosystem performance (i.e. biomass production) are often confounded by those of weather and site potential. The current study overcomes this issue by calculating the difference between actual and expected ecosystem performance (EEP) to generate ecosystem performance anomalies (EPA). This study aims to delineate and quantify average EPA from 2000–2009 within the Greater Platte and Upper Colorado River Basins, USA. Moderate Resolution Imaging Spectroradiometer (MODIS) normalized difference vegetation index (NDVI) images averaged over the growing season (GSN) served as a proxy of actual ecosystem performance. Yearly EEP was determined with rule-based piecewise regression tree models of abiotic data (climate, soils, elevation, etc.), independently created for each land cover. EPA were calculated as the residuals of the EEP to GSN relationship, and characterized as normal performing, underperforming, and overperforming at the 90% confidence level. Validation revealed that EPA values were related to biomass production (R2 = 0.56, P = 0.02) and likely to the proportion of biomass removed by livestock in the Nebraska Sandhills. Overall, 60.6% of the study area was (normal) performing near its EEP, 3.0% was severely underperforming, 5.0% was highly overperforming, and the remainder was slightly underperforming or overperforming. Generally, disturbances such as fires, floods, and insect damage, in addition to high grazing intensity, result in a negative EPA. Conversely, mature stands and appropriate management often result in positive EPA values. This method provides information critical to land managers to evaluate the appropriateness of previous management practices and restoration efforts and quantify disturbance impacts. Results are at a scale sufficient for many of the large management units of the region and for locating areas needing further investigation. Applications of EPA data to monitoring invasive species

    Several indices have been developed to predict survival of brain metastases (BM) based on prognostic factors. However, such models were designed for general brain metastases from different kinds of cancers, and prognostic factors vary between cancers and histological subtypes. Recently, studies have indicated that epidermal growth factor receptor (EGFR) mutation status may be a potential prognostic biological factor in BM from lung adenocarcinoma. Thus, we sought to define the role of EGFR mutation in prognoses and introduce a prognostic model specific for BM from lung adenocarcinoma. Data of 256 patients with BM from lung adenocarcinoma identified with EGFR mutations were collected. Independent prognostic factors were confirmed using a Cox regression model. The new prognostic model was developed based on the results of multivariable analyses. The score of each factor was calculated by six-month survival. Prognostic groups were divided into low, medium, and high risk based on the total scores. The prediction ability of the new model was compared to the three existing models. EGFR mutation and Karnofsky performance status were independent prognostic factors and were thus integrated into the new prognostic model. The new model was superior to the three other scoring systems regarding the prediction of three, six, and 12-month survival by pairwise comparison of the area under the curve. Our proposed prognostic model specific for BM from lung adenocarcinoma incorporating EGFR mutation status was valid in predicting patient survival. Further verification is warranted, with prospective testing using large sample sizes. © 2017 The Authors. Thoracic Cancer published by China Lung Oncology Group and John Wiley & Sons Australia, Ltd.

    Resumption of transient testing at the TREAT facility was approved in February 2014 to meet U.S. Department of Energy (DOE) objectives. The National Nuclear Security Administration’s Global Threat Reduction Initiative Convert Program is evaluating conversion of TREAT from its existing highly enriched uranium (HEU) core to a new core containing low enriched uranium (LEU). This paper describes briefly the initial pre-conceptual designs screening decisions with more detailed discussions on current feasibility, qualification and fabrication approaches. Feasible fabrication will be shown for a LEU fuel element assembly that can meet TREAT design, performance, and safety requirements. The statement of feasibility recognizes that further development, analysis, and testing must be completed to refine the conceptual design. Engineering challenges such as cladding oxidation, high temperature material properties, and fuel block fabrication along with neutronics performance, will be highlighted. Preliminary engineering and supply chain evaluation provided confidence that the conceptual designs can be achieved.

    2004-01-01

    The LHC operating conditions present several challenges to the module performance of the ATLAS Semiconductor Tracker (SCT). This detector consists of four cylindrical barrel layers of silicon strip detectors and 18 disks in the forward and backward directions. Four different module designs exist, one for the barrel and three (inner, middle and outer) for the rings of the disks. A series of several end-cap module pre-production prototypes of inner, middle and outer types has been built and extensively characterized on single module test benches in the institutes of the collaboration. The purpose of this contribution is to summarize the electrical and thermal performance measurements made on these end-cap module pre-production prototypes.

    Full Text Available The aim of this research was to determine the effect of rearing systems for pig production, as concerns performance, meat lipid content, the fatty acid profile, histidinic antioxidants, coenzyme Q10, and TBARs. One hundred pigs were assigned to one of three treatments: intensively reared commercial hybrid pig (I, free range commercial hybrid pig (FR or organically reared crossbred pig (O, according to organic EU Regulations. I pigs showed the best productive performance, but FR and O increased: C20:1n9, Δ9-desaturase (C18 and thioesterase indices in meat. Lipid, dipeptides and CoQ10 appeared correlated to glycolytic and oxidative metabolic pathways. We can conclude that all studied parameters were influenced by the rearing system used, and that differences were particularly evident in the O system, which produced leaner meat with higher oxidative stability. In this respect, the organic pig rearing system promotes and enhances biodiversity, environmental sustainability and food quality.

    The objective of this study was to compare the effects of natural clinoptilolite and modified clinoptilolite on growth performance and antioxidant capacity in broiler chicks. Two hundred forty 1-day-old commercial Arbor Acres broilers were randomly distributed into three treatments, each of which had eight replicates. Each replicate contains 10 chicks. Control (CON) group fed with the basal diets, natural clinoptilolite (NCLI) group fed basal diets with 2 % natural clinoptilolite, and modified clinoptilolite (MCLI) group fed basal diets with 2 % modified clinoptilolite for 42 days. The results showed that the 2 % supplementation of natural clinoptilolite and modified clinoptilolite had no adverse effect on growth performance of broilers at 42 days of age. Relative weights of organs were not influenced by dietary treatments at 21 and 42 days. The activity of total nitric oxide synthase was significantly (P < 0.05) decreased in MCLI group than CON group at 21 days of age. At 21 and 42 days, the activities of glutathione peroxidase, catalase, total superoxide dismutase, total antioxidant capacity (T-AOC) were significantly (P < 0.05) increased in NCLI and MCLI groups than the CON group while there was no difference in T-AOC between CON and NCLI groups. The malondialdehyde content was significantly (P < 0.05) decreased in NCLI and MCLI groups than the CON group. It was concluded that the addition of 2 % natural clinoptilolite and modified clinoptilolite to diet can improve antioxidant capacity in broilers, although their effects on growth performance was negligible.

    Full Text Available The present study was carried out to assess the existing status of compost usage on vegetable production and determine the overall effect of household waste compost (HWC on growth and yield of vegetables and enhancement of soil fertility in the monga areas of Bangladesh. A field survey was conducted on 152 sampled farmers during 2010 to 2011. Questionnaire containing both closed and open-ended questions were used to assess existing production practices of vegetables using compost in both homestead and field conditions. Three field trials at Badargonj and Kawnia upazilas of Rangpur district were conducted taking four treatments i.e. control, recommended doses (RD of fertilizers, HWC at the rate of 10 tha-1, and HWC 10 t ha-1 plus RD as IPNS based with Lal shak, Palong shak, Pui shak and Tomato. Base line survey results indicated inadequate knowledge of the farmers on use and preparation of the household waste compost. Yield data of all vegetables i.e. Tomato, Lal shak, Palong shak and Pui shak indicated that the combined application of nutrients using organic and inorganic sources were significantly better than that of solitary application of inorganic fertilizers. The potential of household waste compost applied @ 10 t ha-1 along with inorganic fertilizers applied was found highly satisfactory in producing Tomato, where yield was recorded 75 t ha-1 in the study area. The fresh yield of Palong shak was found 16 t ha-1 when recommended doses of inorganic fertilizers were applied, but it was about 19 t ha-1 under combined application of HWC @ 10 t ha-1 and inorganic fertilizers following IPNS concept. The fresh yield of Pui shak was found about 49 t ha-1 under combined application of organic and inorganic nutrients. Considering the availability and costs of different composts, it is evinced that HWC contained good amount of NPK which indicates its potentiality to be used as a soil amendment, improving soil fertility and crop productivity.

    Nutrition plays a role in health promotion and well-being, but there is still a lack of knowledge about nutrition-related risk factors in aging cognitive impairment. The purpose of this project was to evaluate the link between nutritional status, cognitive performance and pro/antioxidant balance in healthy elderly subjects residing in a small metropolitan community. The subjects were 69 free-living urban healthy elderly people (41 females and 28 males aged 84+/-7 years, mean +/- standard deviation SD, range 70-89). In this group of elderly subjects an analysis of the diet over the 3 days before the study entry was performed. The nutrients intake for individuals were compared with the Italian Recommended Dietary Allowances (RDA). We also collected residents' background information, nutritional status (Mini Nutritional Assessment, MNA), and data on daily nursing routines in institutions, including nutritional care. Plasma malondialdehyde and erythrocyte glutathione peroxidase activity were evaluated in elderly people as compared to a group of healthy young people (control group) as indices of the oxidative balance. The mean vitamin and mineral intake for participants met the RDAs except for calcium and vitamin D. No difference was observed as regards plasma malondialdehyde between young and elderly subjects: 4.5 (3-6.2) mmol/L vs 4.45 (2.4-5.8) mmol/L respectively, median with range, whereas the latter exhibited higher erythrocyte glutathione peroxidase activity: 16.0 (9.3-48) U/g hemoglobin (Hb) vs 15 (10-35) U/g Hb, respectively, median with range (Pnutritional factors on cognitive performance in older adults.

  11. Low-Temperature Performance of Chinese Automotive Engine Oils-Status and Perspectives

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Performance of automotive engine oils at low temperature has been extensively investigated in the last 50 years. The resulting understanding of engine oil rheology has been used to devise bench tests that predict their performance under cold starting conditions. Cold starting the engine has been essentially overcome for passenger car engines with fuel injection but pumpability of the engine oil has grown more demanding. Two tests (MRV TP1 and the Scanning Brookfield Technique with Gelation Index measurement) have become the measures of quality in pumpability response at low temperatures. As such they have become ASTM Methods and are included in a number of international specifications such as SAE J300 and ILSAC/API GF-1, 2, 3, and 4 accompanied by appropriate limits.For a number of years, the Institute of Materials (IOM) has generated a database for Asia-Pacific engine oils for IOM Subscribers. This database can be used to assess and compare the performance of Chinese engine oils at low temperature to one another and to the larger world of engine oils also covered by the IOM database. This IOM survey of Asia-Pacific provides a complete 36-test analysis of 300 passenger car engine oils from the region including a wide range of chemical analysis, rheological measurements and performance assessments. In this paper we concentrate on the low temperature analysis of the rheology of samples collected in China since 2000.The important factors affecting formulation of engine oils in China today are:1. The recent inclusion of the MRV TP-1 and Scanning Brookfield Gelation Index requirements in China's National Standards for engine oil quality; 2. The availability of higher quality oils; 3. The higher treat rate of additives will require increased attention from the formulators in the selection of VI Improvers and Pour Point Depressants (PPDs). In the latter case, new PPDs are likely to be required to provide formulators with robust and economical solutions to face these new

    The Cosmic Origins Spectrograph (COS) was installed on the Hubble Space Telescope (HST) in May 2009. COS was designed to perform high-sensitivity medium and low-resolution spectroscopy of astronomical objects in the far-ultraviolet (FUV) and near-ultraviolet (NUV) wavelength regimes. Here, we present updates on the time-dependent sensitivities (TDS) for the NUV and FUV detectors, NUV wavelength calibration, and the FUV and NUV dark rates. Additionally, we discuss the move to lifetime position four (LP4) planned for July 2017, including the detector location and impact on resolution.

    Full Text Available This project was designed to assess the effects of time of day and training status on the benefits of caffeine supplementation for cycling performance. Twenty male subjects (Age, 25 years; Peak oxygen consumption, 57 mL·kg−1·min−1 were divided into tertiles based on training levels, with top and bottom tertiles designated as ‘trained’ (n = 7 and ‘untrained’ (n = 7. Subjects completed two familiarization trials and four experimental trials consisting of a computer-simulated 3-km cycling time trial (TT. The trials were performed in randomized order for each combination of time of day (morning and evening and treatment (6mg/kg of caffeine or placebo. Magnitude-based inferences were used to evaluate all treatment effects. For all subjects, caffeine enhanced TT performance in the morning (2.3% ± 1.7%, ‘very likely’ and evening (1.4% ± 1.1%, ‘likely’. Both untrained and trained subjects improved performance with caffeine supplementation in the morning (5.5% ± 4.3%, ‘likely’; 1.0% ± 1.7%, ‘likely’, respectively, but only untrained subjects rode faster in the evening (2.9% ± 2.6%, ‘likely’. Altogether, our observations indicate that trained athletes are more likely to derive ergogenic effects from caffeine in the morning than the evening. Further, untrained individuals appear to receive larger gains from caffeine in the evening than their trained counterparts.

    A series of experiments to monitor the aging performance of Viton® GLT O-rings used in the Model 9975 package has been ongoing since 2004 at the Savannah River National Laboratory. One approach has been to periodically evaluate the leak performance of O-rings being aged in mock-up 9975 Primary Containment Vessels (PCVs) at elevated temperatures. Other methods such as compression-stress relaxation (CSR) tests and field surveillance are also on-going to evaluate O-ring behavior. Seventy tests using PCV mock-ups were assembled and heated to temperatures ranging from 200 to 450 °F. They were leak-tested initially and have been tested periodically to determine if they continue to meet the leak-tightness criterion defined in ANSI standard N14.5-97. Due to material substitution, fourteen additional tests were initiated in 2008 with GLT-S O-rings heated to temperatures ranging from 200 to 400 °F.

    2016-01-01

    LHCb is a precision experiment devoted to the study of CP violation and rare decays of b and c quarks, and to the search for new physics beyond the Standard Model at the Large Hadron Collider (LHC) at CERN. The Ring-Imaging Cherenkov (RICH) system is a key component of the LHCb experiment: it consists of two RICH detectors that provide charged particle identification over a wide momentum range (2-100 GeV/c) and angular acceptance (15-300 mrad). The LHCb RICH system has been performing extremely well during Run 1 and is providing the LHCb experiment also in Run 2 with a robust, reliable and precise particle identification system. Performance of the RICH detectors measured from data will be presented, with special reference to its dependence on calibration parameters and event multiplicities. The LHCb experiment is preparing for an upgrade during the second LHC long shutdown (2019-2020) in order to fully exploit the LHC flavour physics potential. A five-fold increase in instantaneous luminosity is foreseen reac...

    We present laboratory results of the closed-loop performance of the Magellan Adaptive Optics (AO) Adaptive Secondary Mirror (ASM), pyramid wavefront sensor (PWFS), and VisAO visible adaptive optics camera. The Magellan AO system is a 585-actuator low-emissivity high-throughput system scheduled for first light on the 6.5 meter Magellan Clay telescope in November 2012. Using a dichroic beamsplitter near the telescope focal plane, the AO system will be able to simultaneously perform visible (500-1000 nm) AO science with our VisAO camera and either 10 micron or 3-5 micron science using either the BLINC/MIRAC4 or CLIO cameras, respectively. The ASM, PWS, and VisAO camera have undergone final system tests in the solar test tower at the Arcetri Institute in Florence, Italy, reaching Strehls of 37% in i'-band with 400 modes and simulated turbulence of 14 cm ro at v-band. We present images and test results of the assembled VisAO system, which includes our prototype advanced Atmospheric Dispersion Corrector (ADC), prot...

    The Gemini Planet Imager is a high-contrast near-infrared instrument specifically designed to image exoplanets and circumstellar disks over a narrow field of view. We use science data and AO telemetry taken during the first 1.5 yr of the GPI Exoplanet Survey to quantify the performance of the AO system. In a typical 60 sec H-band exposure, GPI achieves a 5$\\sigma$ raw contrast of 10$^{-4}$ at 0.4"; typical final 5$\\sigma$ contrasts for full 1 hr sequences are more than 10 times better than raw contrasts. We find that contrast is limited by bandwidth wavefront error over much of the PSF. Preliminary exploratory factor analysis can explain 60-70% of the variance in raw contrasts with combinations of seeing and wavefront error metrics. We also examine the effect of higher loop gains on contrast by comparing wavefront error maps reconstructed from AO telemetry to concurrent IFS images. These results point to several ways that GPI performance could be improved in software or hardware.

    The aim of this study was to test the hypothesis that magnesium supplementation influences the physical performance of volleyball players, as the efficacy of this approach remains questionable. Twenty-five professional male volleyball players were assigned randomly to experimental (350 mg Mg · d(-1), 4 weeks) and control groups (500 mg maltodextrin · d(-1), 4 weeks) maintaining inter-group homogeneity of urinary magnesium. Erythrocyte, plasma and urinary magnesium levels, plasma creatine kinase activity, lactate production, maximal oxygen uptake (VO2 max) and plyometric (squat jump, countermovement jump, countermovement jump with arm swing) and isokinetic (peak torque, potency and total work) performances were evaluated before (T0) and after (T1) supplementation. Levels of erythrocyte and urinary magnesium and creatine kinase activity and VO2 max remained within normal ranges in both groups. Plasma magnesium decreased significantly only within the experimental group. Significant decreases in lactate production and significant increases (of up to 3 cm) in countermovement jump and countermovement jump with arm swing values were detected in the experimental group following magnesium supplementation, but not in the control group at T1. It is concluded that magnesium supplementation improved alactic anaerobic metabolism, even though the players were not magnesium-deficient.

    Clinical and biochemical predictors of extreme longevity would be useful in geriatric practice but have still not been clearly defined. To identify the best nongenetic predictors of survival in centenarians, we examined 340 individuals aged 100+ years. A detailed questionnaire was completed, and comprehensive geriatric assessment and blood analyses were performed. Survival of study participants was checked annually over the period of 10 years. In the univariate Cox proportional hazards model, a longer survival of centenarians was correlated with a higher adjusted Mini-Mental State Examination (MMSE(adj)) score (p HR = 0.978 per each MMSE(adj) point, 95% CI: 0.964-0.993, p = .004; HR = 0.900 per each ADL point, 95% CI: 0.842-0.962, p = .002, respectively). In multivariate analysis with the ADL score substituted by the IADL(adj) score, the only predictor of survival was MMSE(adj) (HR = 0.973 per each MMSE(adj) point, 95% CI: 0.958-0.988, p = .0006). Cognitive and functional performances are predictors of survival in centenarians. © The Author 2014. Published by Oxford University Press on behalf of The Gerontological Society of America.

    Full Text Available Knee osteoarthritis (OA is a leading cause of functional disability among American adults. Obesity is a strong independent risk factor for OA. While research emphasizes the role of obesity in the OA-physical function relationship, the extent to which weight status impacts salient physical, health, and pain measures in older, knee OA patients is not well delineated. The primary aim of this study was to assess differences in mobility performance (stair climb and 400-meter walk, mobility-related self-efficacy, pain symptoms (WOMAC, and measures of accelerometer-determined physical activity (PA as a function of weight status. Analysis of covariance was conducted to examine differences on the dependent variables. Obese class III patients were outperformed by their counterparts on nearly every measure of mobility, mobility-related self-efficacy, and the assessment of pain symptoms. These outcomes did not differ among other weight comparisons. Normal weight subjects outperformed classes I, II, and III counterparts on most measures of PA (engagement in moderate or greater PA and total weekly steps. Additionally, overweight participants outperformed obese class II participants and obese class I participants outperformed obese classes II and III participants on total weekly steps. Collectively, these findings underscore the meaningful differences observed in relevant OA outcomes as a function of increasing levels of body weight.

    Low visibility(fog is very hazardous to air/land traffic and is beeing particularly emphasized at National Weather Service(NWS) of NOAA and in NextGen, a future Air Traffic Management System of Federal Aviation Administration (FAA), United States. As of now however, fog forecast is still not operational guidance from National Centers for Environment Prediction (NCEP), an official numerical weather prediction (NWP) center of NWS, due to its complexity and computational resource limitation. Instead, it is only diagnosed by local weather forecasters through either model output statistics (MOS) or other variables based upon their forecasting experience. Nevertheless, research on numerical fog prediction has been conducting at NCEP. Recently, in an effort to add it to NCEP’s operational guidance as a step to echo the requirement from NWS and the NextGen of FAA, low visibility/fog forecast was experimentally implemented and tested at NCEP. In this paper, predictions of fog and low visibility (fog from two ensemble forecast systems are also presented. One is the Short Range Ensemble Forecast System (SREF), the other is the Very Sort Range Ensemble Forecast System (VSREF). Through verifications, deterministically and probabilistically from November 2009 to March 2010 on North America, the fog and low visibility predictabilities for various models and ensembles are compared and discussed. The results show that the general performances of fog and low visibility prediction from the single model forecast systems are still low, but the application of ensemble, either in low or high resolution, has shed light on its performance improvement. Furthermore through this study, where the efforts should be focused on in the models or methods are also suggested.

    Full Text Available Seventy two rabbits (Hycole, (♂+♀ 5 weeks old were divided into 2 experimental (EG and one control (CG group. The feed mixture A in control (CG did not contain any coccidiostat. In the first experimental group (EG1 was tested a complete granulated mixture B enriched with 30 g dry extract Eleutherococcus senticosus per 100 kg mixture. The animals were fed mixture B in combination with probiotic strain Enterococcus faecium EF AL 41 applied orally at a dose (10 9 CFU. ml-1 500 μl per animal in drinking water during 21 days. In the second group (EG2 was tested complete granulated mixture B. The experiment lasted 42 days. Body weight and feed consumption were registered weekly. Samples of faeces were taken at days 1, 21 and 42 to monitor the counts and effect of natural substances. Blood samples were also taken to check biochemical parameters using commercial kits. The samples for microbiological analyses were treated by the standard microbiological method according to ISO with appropriate media. Results presented in this study introduce different mechanisms of action for different classes of feed additives and how these may influence the observed live performance benefits. Application of Eleutherococcus extract in combination with EF AL 41 strain in rabbits was beneficial for performance. Additives reduced counts of S. aureus and Clostridium-like sp in faeces. Bioactive substances can be beneficial for animal health as was repeatedly confirmed by our results (mortality in EG1- 12%, EG2 - 8% compared to CG- 17%.

    Prognostic factors (e.g., gender, tumor stage, and hypoxia) have an impact on survival in patients with head and neck cancer. Thus, the impact of physical status and comorbidities on treatment decision and survival were evaluated. A total of 169 primary, inoperable patients with squamous cell cancer of the head and neck were retrospectively investigated. Patients were treated with hyperfractionated accelerated radio(chemo)therapy (HARcT) or hypofractionated radio(chemo)therapy (HypoRcT). Depending on the individual patient's situation (Karnofsky Performance Index, KPI), treatment for patients with a KPI of 80-100% was generally radiochemotherapy and for patients with a KPI ≤ 70% treatment was radiotherapy alone. In addition, all comorbidities were evaluated. Uni- and multivariate proportional hazards model were used, and overall survival (OS) was estimated by the Kaplan-Meier method. Treatment consisted of HARcT for 76 patients (45%), HART for 28 patients (17%), HypoRcT for 14 patients(8%), and HypoRT for 51 patients (30%). Of the patients, 107 patients (63%) presented with a KPI of 80-100%. OS (20%) was significantly better for patients with a KPI of 80-100%, while the OS for patients with a KPI ≤ 70% was 8% (p KPI, total irradiation dose (> 70 Gy), and chemotherapy were significant prognostic factors for better OS. Our retrospective analysis shows that performance status with dependency on comorbidities was an independent risk factor for OS.

    Full Text Available ABSTRACT The objective of this study was to investigate the influence of two cleaning and disinfection programs on broiler performance and on the microbiological status of the facilities. This trial was an observational study of comparative character. Two experiments were conducted, with 960 birds each. Both experiments were carried out in a positive-pressure broiler house. Broilers were distributed in pens equipped with a bell drinker and a tube feeder each. In the first experiment, new wood shavings were used as litter material, and in the second, reused wood shavings were used. Two treatments with16 replicates of 30 birds each were evaluated. The regular treatment consisted of dry and wet organic matter removal, followed by washing. The European treatment consisted of dry organic matter removal, humidification, washing with water under high pressure, detergent application, rinsing, and application of two combined disinfectants: glutaraldehyde 250g/L + formaldehyde 185g/L; p-chlor-m-cresol 210 g/L. Biosecurity measures were adopted during daily management tasks to prevent cross contamination between treatments. The effectiveness of the treatments was evaluated by microbiological analysis performed before and after treatment applications, as well as by broiler performance results. Live performance results were similar between both treatments when broilers were reared on new litter. When reused word-shavings were used as litter material, the European treatment promoted better broiler performance. The European treatment was more effective than the regular treatment in reducing total microbial counts in the facilities when reused wood shavings were used as litter material, and positively influenced broiler performance.

    Gastric cancer is one of most common types of cancers. Metastatic gastric cancer has a poor prognosis and is accepted as incurable at this stage. Treatment of metastatic gastric cancer did not progress substantially until new targeted agents have come out. Recently published ToGA trial showed promising results in HER2 overexpressing metastatic gastric cancer. In this case we present a case with an excellent complete response with anti-HER2 treatment. Most importantly, we wanted to emphasize (1) the importance of early determination of HER2 overexpression, and (2) to draw attention of anti-HER2 agents in the first line treatment even in patients with a poor performance status.

    The objective of this study was to evaluate carob pods and their effect on growth performance, antioxidant activities, carcass and caecal characteristics and equilibrium modification of the caecal microbiota population of growing NZW rabbits. Eighty weaned rabbits (initial body weight: 625.00 ± 26.46 g) were randomly allocated into four dietary groups of 20 rabbits each until 90 days of age. Dietary groups were as follows: C (basal diet with no supplementation), CP1 (basal diet + 2.5% carob pods), CP2 (basal diet + 5% carob pods) and CP3 (basal diet + 10% carob pods). Rabbits given the CP2 diet had significantly higher daily and final body weights compared with the other experimental groups. The increase in inclusion rate of carob pods significantly decreased feed intake, whereas carob pods at 5% in the CP2 group recorded the best value of feed conversion ratio. Rabbits in the CP3 group showed the worst slaughter weight and carcass dressing percentage weight. No significant effect was found on meat protein and ash contents. Cholesterol, low-density lipoprotein, high-density lipoprotein and triglycerides decreased significantly (p CP2 and CP3 groups, the activities of glutathione peroxidase, glutathione S-transferase, catalase and superoxide dismutase increased, whereas the concentration of thiobarbituric acid-reactive substance decreased significantly. Rabbits given the CP2 diet had a significantly higher volatile fatty acid concentration and a lower pH in content of the caecum compared to the other groups. The data of microbial analysis for C group showed a significant increase in Escherichia coli and Clostridium counts. Lactobacillus and Bacillus counts increased significantly more in the CP2 and CP3 groups than in the other groups. In conclusion, 5% of carob pods in the diet stimulated the performance of growing rabbits, and thus, it has potential as an unconventional feed resource for rabbits without any adverse effects.

  10. Social status and housing factors affect reproductive performance of pregnant sows in groups.

    2017-08-01

    Group-housing systems for pregnant sows are considered a welfare-promoting alternative to the individual stall. A major concern associated with pregnant sows housed in group pens is increased aggression at mixing and at feeding, which may cause chronic stress among some of the sows in the group due to low feed intake and social stress. Prolonged activation of the stress axis, based on elevated cortisol levels, may inhibit or impair reproductive success via disruption of the reproductive axis. Mixing sows into groups shortly after insemination evokes a stress response, which may affect fertilization and implantation due to sustained, elevated cortisol levels that disrupt reproductive processes. Yet, most studies reported minimal effects of group housing sows during pregnancy on reproduction or cortisol-related stress response. Differences between housing systems-in terms of group size, floor-space allowance, feeding system, and genetics-could account for these unexpected results. Indeed, interrupted feed intake, especially in early pregnancy, and sustained aggression in late pregnancy are two unfavorable social stresses that deserve special attention in order to achieve good reproductive performance. Unfortunately, most studies do not consider other factors, such as social rank and parity, which may interactively affect reproductive success and aggressive behavior of sows, especially in group-pen systems. © 2017 Wiley Periodicals, Inc.

    Breakfast has been labeled the most important meal of the day, but are there data to support this claim? We summarized the results of 47 studies examining the association of breakfast consumption with nutritional adequacy (nine studies), body weight (16 studies), and academic performance (22 studies) in children and adolescents. Breakfast skipping is highly prevalent in the United States and Europe (10% to 30%), depending on age group, population, and definition. Although the quality of breakfast was variable within and between studies, children who reported eating breakfast on a consistent basis tended to have superior nutritional profiles than their breakfast-skipping peers. Breakfast eaters generally consumed more daily calories yet were less likely to be overweight, although not all studies associated breakfast skipping with overweight. Evidence suggests that breakfast consumption may improve cognitive function related to memory, test grades, and school attendance. Breakfast as part of a healthful diet and lifestyle can positively impact children's health and well-being. Parents should be encouraged to provide breakfast for their children or explore the availability of a school breakfast program. We advocate consumption of a healthful breakfast on a daily basis consisting of a variety of foods, especially high-fiber and nutrient-rich whole grains, fruits, and dairy products.

    Abstract The Child–Turcotte–Pugh (CTP) score is widely used worldwide to predict outcomes across a broad spectrum of liver diseases, mainly cirrhosis. Portal hypertension and variceal bleed are significant causes of morbidity and mortality in cirrhotic patients, although the variceal status is not incorporated into the classical CTP score. We sought to determine whether the inclusion of variceal status, specifically the Child–Turcotte–Pugh–Kumar (CTPK) score, would improve the utility of the classical CTP score to predict the clinical outcomes of cirrhotic patients in a single but high-volume center in China. We retrospectively analyzed the records of 253 patients from January 1, 2014 to December 31, 2014 and performed follow-up for at least 12 months. The CTPK score and the CTP score were obtained as soon as possible after the patient's admission. Telephone follow-up was performed to assess survival situations. At 3 and 12 months, the cumulative number of deaths was 9.1% (n = 23) and 13.8% (n = 35), respectively. In the multivariate Cox proportional hazards models, the CTPK score was independently associated with death within 3 and 12 months after adjusting for potential confounders. The predictive ability related to the 2 scores was evaluated by the area under the receiver operating characteristic curve (AUC-ROC) respectively. At 3 months of enrollment, the AUCs of CTPK and CTP were 0.814 and 0.838, respectively. At 12 months of enrollment, the AUCs of CTPK and CTP were 0.825 and 0.840, respectively. No significant difference between time points was observed. Both the CTPK score and the CTP score displayed prognostic value in cirrhotic patients, as the Kaplan–Meier analysis showed that the CTPK score could clearly discriminate patients in the intermediate term (P < 0.001).

    The Child-Turcotte-Pugh (CTP) score is widely used worldwide to predict outcomes across a broad spectrum of liver diseases, mainly cirrhosis. Portal hypertension and variceal bleed are significant causes of morbidity and mortality in cirrhotic patients, although the variceal status is not incorporated into the classical CTP score. We sought to determine whether the inclusion of variceal status, specifically the Child-Turcotte-Pugh-Kumar (CTPK) score, would improve the utility of the classical CTP score to predict the clinical outcomes of cirrhotic patients in a single but high-volume center in China.We retrospectively analyzed the records of 253 patients from January 1, 2014 to December 31, 2014 and performed follow-up for at least 12 months. The CTPK score and the CTP score were obtained as soon as possible after the patient's admission. Telephone follow-up was performed to assess survival situations.At 3 and 12 months, the cumulative number of deaths was 9.1% (n = 23) and 13.8% (n = 35), respectively. In the multivariate Cox proportional hazards models, the CTPK score was independently associated with death within 3 and 12 months after adjusting for potential confounders. The predictive ability related to the 2 scores was evaluated by the area under the receiver operating characteristic curve (AUC-ROC) respectively. At 3 months of enrollment, the AUCs of CTPK and CTP were 0.814 and 0.838, respectively. At 12 months of enrollment, the AUCs of CTPK and CTP were 0.825 and 0.840, respectively. No significant difference between time points was observed. Both the CTPK score and the CTP score displayed prognostic value in cirrhotic patients, as the Kaplan-Meier analysis showed that the CTPK score could clearly discriminate patients in the intermediate term (P < 0.001).The CTPK score provides reliable prediction of mortality in Chinese cirrhotic patients for both short-term and medium-term prognoses, although it is not superior to the CTP score. Therefore, the CTP

    A series of experiments to monitor the aging performance of Viton® GLT O-rings used in the Model 9975 package has been ongoing since 2004 at the Savannah River National Laboratory. Seventy tests using mock-ups of 9975 Primary Containment Vessels (PCVs) were assembled and heated to temperatures ranging from 200 to 450 ºF. They were leak-tested initially and have been tested periodically to determine if they meet the criterion of leak-tightness defined in ANSI standard N14.5-97. Fourteen additional tests were initiated in 2008 with GLT-S O-rings heated to temperatures ranging from 200 to 400 ºF. High temperature aging continues for 23 GLT O-ring fixtures at 200 – 270 ºF. Room temperature leak test failures have been experienced in all of the GLT O-ring fixtures aging at 350 ºF and higher temperatures, and in 8 fixtures aging at 300 ºF. The remaining GLT O-ring fixtures aging at 300 ºF have been retired from testing following more than 5 years at temperature without failure. No failures have yet been observed in GLT O-ring fixtures aging at 200 ºF for 54-72 months, which is still bounding to O-ring temperatures during storage in K-Area Complex (KAC). Based on expectations that the fixtures aging at 200 ºF will remain leak-tight for a significant period yet to come, 2 additional fixtures began aging in 2011 at an intermediate temperature of 270 ºF, with hopes that they may reach a failure condition before the 200 ºF fixtures. High temperature aging continues for 6 GLT-S O-ring fixtures at 200 – 300 ºF. Room temperature leak test failures have been experienced in all 8 of the GLT-S O-ring fixtures aging at 350 and 400 ºF. No failures have yet been observed in GLT-S O-ring fixtures aging at 200 - 300 ºF for 30 - 36 months. For O-ring fixtures that have failed the room temperature leak test and been disassembled, the O-rings displayed a compression set ranging from 51 – 96%. This is greater than seen to date for any packages inspected during KAC field

    A series of experiments to monitor the aging performance of Viton® GLT O-rings used in the Model 9975 package has been ongoing since 2004 at the Savannah River National Laboratory. One approach has been to periodically evaluate the leak performance of O-rings being aged in mock-up 9975 Primary Containment Vessels (PCVs) at elevated temperatures. Other methods such as compression-stress relaxation (CSR) tests and field surveillance are also on-going to evaluate O-ring behavior. Seventy tests using PCV mock-ups were assembled and heated to temperatures ranging from 200 to 450 ºF. They were leak-tested initially and have been tested periodically to determine if they continue to meet the leak-tightness criterion defined in ANSI standard N14.5-97. Due to material substitution, fourteen additional tests were initiated in 2008 with GLT-S O-rings heated to temperatures ranging from 200 to 400 ºF. High temperature aging continues for 23 GLT O-ring fixtures at 200 – 270 ºF. Room temperature leak test failures have been experienced in all of the GLT O-ring fixtures aging at 350 ºF and higher temperatures, and in 8 fixtures aging at 300 ºF. The earliest 300 °F GLT O-ring fixture failure was observed at 34 months. The remaining GLT O-ring fixtures aging at 300 ºF have been retired from testing following more than 5 years at temperature without failure.

They were leak-tested initially and have been tested periodically to determine if they continue to meet the leak-tightness criterion defined in ANSI standard N14.5-97. Due to material substitution, a smaller test matrix with fourteen additional tests was initiated in 2008 with GLT-S O-rings heated to temperatures ranging from 200 to 400 ºF. Leak test failures have been experienced in all of the GLT O-ring fixtures aging at 350 ºF and higher temperatures, and in 8 fixtures aging at 300 ºF. The 300 °F GLT O-ring fixtures failed after 2.8 to 5.7 years at temperature. The remaining GLT O-ring fixtures aging at 300 ºF were retired from testing following more than 5 years at temperature without failure. No failures have yet been observed in GLT O-ring fixtures aging at 200 ºF for 9 to 10.5 years, or in GLT O-ring fixtures aging at 270 ºF for 5.7 years. These aging temperatures bound O-ring temperatures anticipated during normal storage in K-Area Complex (KAC). Leak test failures have been experienced in all of the GLT-S O-ring fixtures aging at 300 ºF and above. No failures have yet been observed in GLT-S O-ring fixtures aging at 200 and 250 ºF for 6.9 to 7.5 years. Data from the O-ring fixtures are generally consistent with results from compression stress relaxation testing, and provide confidence in the predictive models based on those results

    Submarine watch-standers adhere to a 6 hour-on, 12 hour-off (6/12) watch-standing schedule, yoking them to an 18-hr day, engendering circadian desynchronization and chronic sleep deprivation. Moreover, the chronic social crowding, shift work, and confinement of submarine life provide additional stressors known to correlate with elevated secretory immunoglobulin A (sIgA) and cortisol levels, reduced performance, immunologic dysfunction, malignancies, infections, gastrointestinal illness, coronary disease, anxiety, and depression. We evaluated an alternative, compressed, fixed work schedule designed to enhance circadian rhythm entrainment, sleep hygiene, performance, and health on 10 underway submariners, who followed the alternative and 6/12 schedules for approximately 2 weeks each. We measured subjects" sleep, cognitive performance, and salivary biomarker levels. Pilot analysis of the salivary data on one subject utilizing ELISA suggests elevated biomarker levels of stress. Average PM cortisol levels were 0.2 μg/L (normal range: nondetectable - 0.15 μg/L), and mean sIgA levels were 562 μg/ml (normal range: 100-500 μg/ml). Future research exploiting real-time salivary bioassays, via fluorescent polarimetry technology, identified by the Office of Naval Research (ONR) as a future Naval requirement, allows researchers to address correlations between stress-induced elaboration of salivary biomarkers with physiological and performance decrements, thereby fostering insight into the underway submariner"s psychoimmunological status. This may help identify strategies that enhance resilience to stressors. Specifically, empirically-based modeling can identify optimal watch-standing schedules and stress-mitigating procedures -- within the operational constraints of the submarine milieu and the mission --that foster improved circadian entrainment and reduced stress reactivity, enhancing physiological health, operational performance, safety, and job satisfaction.

    Relationships between micronutrient intake and status, and micronutrient status and performance in tests of intelligence were investigated in a group of adolescents (13-14 years old). Dietary intakes were assessed using a 7 d weighed dietary record method, coupled with the collection of duplicate diets. Vitamin and trace mineral intakes calculated using food composition tables were compared with those obtained by direct analysis of duplicate diets. Micronutrient status was judged via a range of biochemical indices measured in blood samples taken after a 12-15 h fast. Blood samples were taken both before and after a 16-week period of vitamin and trace mineral supplementation. Individual tests of verbal and nonverbal intelligence were also performed pre- and post-supplementation. The results of this study indicate that the use of food table data may lead to substantial over- or underestimation of the intake of several micronutrients. In general, the total calculated or analysed amount of a specific micronutrient consumed did not adequately predict status, as judged by a range of biochemical indices. There were significant changes in status measurements over the 16-week study period, irrespective of supplementation, and these changes were markedly influenced by the initial status of the subject. There was no effect of supplementation on performance in tests of intelligence. However, there was a significant association between plasma ascorbic acid and initial non-verbal intelligence quotient (IQ) in the boys, and between whole blood glutathione peroxidase (EC 1.11.1.9) activity and non-verbal and verbal IQ in both sexes. These findings are discussed in relation to other recent studies of the influence of micronutrient supplementation on the psychological performance of children.

    Full Text Available Abstract Background Owing to the mechanics of anti-doping regulation via the World Anti-Doping Agency's Prohibited List, nutritional supplement use received little attention in comparison to the prevalence of doping. The aims of this study were to investigate supplement use, identify groups of athletes with high levels of supplement use and the prevalence of concomitant use of supplements. Methods Survey data from 847 high-performing athletes in the UK were analysed using descriptive statistics. The survey, conducted by UK Sport, consisted of questions regarding knowledge of the prohibited substances, testing procedure, nutritional supplement use and perceptions of the doping problem. The proportion of supplement users and the relative use of each supplement were compared by age, gender and professional status. Results Among 874 high-performing athletes in the UK sample, 58.8% of them reported the use of at least one nutritional supplement. Among supplement users, 82.6% used more than one and 11.5% reported use of more than five nutritional supplements. Of the 9 supplements listed, multivitamins (72.6% and vitamin C (70.7% were used most, followed by creatine (36.1%, whey protein (31.7%, echinacea (30.9%, iron (29.9% and caffeine (23.7%. Less than 11% reported the use of magnesium or ginseng. Creatine use was typically associated with males regardless of status and across all ages, whereas iron was characteristically used by females. A 'typical' supplement user is male, between 24 and 29 years of age, involved in professional sport and using a combination of supplements. Male professional players between age 30 and 34 years, and female non-professional athletes between 24 and 29 years of age also represented a considerable proportion of supplement users. Athletes older than 40 years of age were practically non-users. Concomitant use of supplements is characteristic of male users more than females. Conclusion As supplement use has been previously

    Full Text Available Abstract Background The Cerebral Performance Category (CPC score is widely used in research and quality assurance to assess neurologic outcome following cardiac arrest. However, little is known about the inter- and intra-reviewer reliability of the CPC. Methods We undertook an investigation to assess the inter-reviewer and source document reliability of the CPC among a cohort of survivors from out-of-hospital ventricular fibrillation cardiac arrest (n = 131 in a large metropolitan area between November 1, 2003 and December 31, 2005. Subjects with a CPC of 1 or 2 were classified as favorable outcome and those with CPC 3 or greater were classified as unfavorable outcome. One abstractor first used the discharge summary alone to determine the CPC. All 3 abstractors independently reviewed the entire hospital record. Reliability was assessed by determining the proportion of determinations that agreed between abstractors and the respective kappa statistics. We also evaluated the implications for determining survival with favorable neurological outcome when survival to hospital discharge was 20% and 30%. Results When the entire hospital record was used to determine CPC, favorable neurologic outcome (CPC 1 or 2 was recorded in 92% by abstractor 1, 89% by abstractor 2, and 74% by abstractor 3. Agreement was 96% (kappa = 0.78 between abstractors 1 and 2, 84% (kappa = 0.49 between abstractors 2 and 3, 82% (kappa = 0.38 between abstractors 1 and 3. The 3-way kappa was 0.50. Agreement was 90% (kappa = 0.71 between the discharge summary alone and the entire hospital record. If the results from review of the entire record are applied to a circumstance where survival to discharge is 20%, favorable neurologic status would occur in 18.4% for abstractor 1, 17.8% for abstractor 2, and 14.8% for abstractor 3. For survival to hospital discharge of 30%, favorable neurologic status would occur in 27.6% for abstractor 1, 26.7% for abstractor 2, and 22.2% for abstractor 3

    Purpose. The purpose of the first study was to ascertain the extent to which differences were present in the STAAR Mathematics and Science test scores by Grade 5 and Grade 8 student economic status. The purpose of the second study was to examine differences in Grade 5 STAAR Mathematics and Science test performance by gender and by ethnicity/race (i.e., Asian, Black, Hispanic, and White). Finally, with respect to the third study in this journal-ready dissertation, the purpose was to investigate the STAAR Mathematics and Science test scores of Grade 8 students by gender and by ethnicity/race (i.e., Asian, Black, Hispanic, and White). Method. For this journal-ready dissertation, a non-experimental, causal-comparative research design (Creswell, 2009) was used in all three studies. Grade 5 and Grade 8 STAAR Mathematics and Science test data were analyzed for the 2011-2012 through the 2014-2015 school years. The dependent variables were the STAAR Mathematics and Science test scores for Grade 5 and Grade 8. The independent variables analyzed in these studies were student economic status, gender, and ethnicity/race. Findings. Regarding the first study, statistically significant differences were present in Grade 5 and Grade 8 STAAR Mathematics and Science test scores by student economic status for each year. Moderate effect sizes (Cohen's d) were present for each year of the study for the Grade 5 STAAR Mathematics and Science exams, Grade 8 Science exams, and the 2014-2015 Grade 8 STAAR Mathematics exam. However, a small effect size was present for the 2011-2012 through 2013-2014 Grade 8 STAAR Mathematics exam. Regarding the second and third study, statistically significant differences were revealed for Grade 5 and Grade 8 STAAR Mathematics and Science test scores based on gender, with trivial effect sizes. Furthermore, statistically significant differences were present in these test scores by ethnicity/race, with moderate effects for each year of the study. With regard to

Changes in fasting insulin, homeostasis model assessment of insulin resistance, and catalase activity were not significant in the inulin group when compared with the maltodextrin group. Glutathione peroxidase activity remained unchanged in both groups.ConclusionInulin supplementation may improve some glycemic and antioxidant indices and decrease malondialdehyde levels in women with type 2 diabetes. Further investigations are needed in order to confirm the positive effects that inulin may have on the glycemic and antioxidant indices of patients with type 2 diabetes.

    The aim of this study was to investigate the efficacy of Sangrovit(®) , a plant-derived feed additive, given throughout the nursery stage via feed at 15 ppm and 50 ppm, on the health status and performance of weaners against negative controls. In a 900-sow farrow-to-finish farm, a total of 864 piglets were divided into three groups: (i) negative controls (NC); (ii) Sang 15: same feed as NCs, plus 15 g Sangrovit(®) /t of feed; (iii) Sang 50: same feed as NCs plus 50 g Sangrovit(®) /t of feed. The results indicated that administration of 50 ppm(-) Sangrovit(®) had the most beneficial effects on growth performance in weaning pigs. Specifically there was increase of body weight and average daily gain, as well as reduction of feed conversion ratio. Blood analysis from the Sang groups and especially the Sang 50 group revealed low values of haptoglobin and serum amyloid A.

    The increasing number of unfit patients calls for better risk assessment prior to initiating anti-tumor treatment. This is a major concern in the prevention and reduction of treatment-related complications. The aim of our study was to evaluate the nutritional status for the risk assessment of patients qualifying to receive the gemcitabine and oxaliplatin (GEMOX) regimen. This single-center, retrospective study examined baseline clinical and biological characteristics in a cohort of 165 unselected, consecutive cancer patients receiving GEMOX. Malnutrition was defined as either body mass index (BMI) 10% over 3 mo, or albuminemia 0.05). Median relative dose-intensity was 0.90 (0.17-1.04). GEMOX dose-intensity correlated negatively with loss of baseline weight (r = -0.24, P chemotherapy, median PS (P nutritional status, including albuminemia and BMI, is recommended.

    The aim of this study was to investigate the relationship between gastrointestinal symptoms, nutritional balance, and performance status in patients receiving palliative care for advanced cancers originating in different sites. We studied a total of 105 patients. Upper gastrointestinal symptoms, Eastern Cooperative Oncology Group Performance Status score (ECOG-PS), dietary intakes, anthropometric measures, and some serum proteins were determined. Unintentional weight loss, alterations in anthropometric measures, and highest number of symptoms were greater in patients with lung and stomach cancer. No differences were found in ECOG-PS according to cancer site. Patients with gastric or lung cancer have most evidence of protein-calorie malnutrition and a higher prevalence of upper gastrointestinal symptoms. The performance status is not affected by tumor site. Early nutritional support should be planned for all patients with cancer, especially for patients with gastric or lung cancer.

    Full Text Available (1 Background: studies with able-bodied athletes showed that performance might possibly be influenced by vitamin D status. Vitamin D seems to have a direct impact on neuromuscular function by docking on vitamin D receptors in the muscle tissue. Additionally, a high prevalence of vitamin D deficiency was shown not only in infants and in the elderly but also in healthy adults and spinal cord injured individuals. Therefore, the aim of our study was to investigate whether a vitamin D dose of 6000 IU daily over 12 weeks would be sufficient to increase vitamin D status in indoor wheelchair athletes to a normal or optimal vitamin D level and whether vitamin D deficiency is associated with an impairment in muscle performance in these individuals; (2 Methods: vitamin D status was assessed in indoor elite wheelchair athletes in order to have a baseline measurement. If vitamin D status was below 75 nmol/L, athletes were supplemented with 6000 IU of vitamin D daily over 12 weeks. A vitamin D status over 75 nmol/L was supplemented with a placebo supplement. Vitamin D status, as well as a Wingate test and an isokinetic dynamometer test, were performed at baseline and after six and 12 weeks; (3 Results: 20 indoor elite wheelchair athletes participated in this double-blind study. All of these athletes showed an insufficient vitamin D status at baseline and were, therefore, supplemented with vitamin D. All athletes increased vitamin D status significantly over 12 weeks and reached an optimal level. Wingate performance was not significantly increased. Isokinetic dynamometer strength was significantly increased but only in the non-dominant arm in isometric and concentric elbow flexion; (4 Conclusion: a dose of 6000 IU of vitamin D daily over a duration of 12 weeks seems to be sufficient to increase vitamin D status to an optimal level in indoor wheelchair athletes. It remains unclear, whether upper body performance or muscle strength and vitamin D status are

    Full Text Available Community dental health status for permanent teeth in determined by the DMF-T (Decayed Misssing and Filled Teeth. The DMF-T in a number of industrialized nations shows a tendency to drop while the trend in developing nations is increasing. In Indonesia dental caries is still the foremost problem in oral and dental diseases, Prevalence of dental caries is around 85%-99%. The DMF-T is varied, reflect geographic and ages variations. In three decade's the intensity of dental caries is increasing with each decade, 0,70 DMF-T in 1970 to be 2,30 DMF-T in 1980 and 2,70 DMF-Tin 1990. Goal of dental caries control for 2010 is DMF-T ≤ 1 for 12 years age group. Baseline study is therefore necessary to ascertain DMF-T, PTI (Performed Treatment Index and RTI (Required Treatment Index.

    The aim of this study was (i) to evaluate whether homocysteine (Hcy), total antioxidant status (TAS), and biological markers of muscle injury would be affected by time of day (TOD) in football players and (ii) to establish a relationship between diurnal variation of these biomarkers and the daytime rhythm of power and muscle fatigue during repeated sprint ability (RSA) exercise. In counterbalanced order, 12 football (soccer) players performed an RSA test (5 x[6 s of maximal cycling sprint + 24 s of rest]) on two different occasions: 07:00-08:30 h and 17:00-18:30 h. Fasting blood samples were collected from a forearm vein before and 3-5 min after each RSA test. Core temperature, rating of perceived exertion, and performances (i.e., Sprint 1, Sprint 2, and power decrease) during the RSA test were significantly higher at 17:00 than 07:00 h (p RSA test. However, biomarkers of antioxidant status' resting levels (i.e., total antioxidant status, uric acid, and total bilirubin) were higher in the morning. This TOD effect was suppressed after exercise for TAS and uric acid. In conclusion, the present study confirms diurnal variation of Hcy, selected biological markers of cellular damage, and antioxidant status in young football players. Also, the higher performances and muscle fatigue showed in the evening during RSA exercise might be due to higher levels of biological markers of muscle injury and lower antioxidant status at this TOD.

    Full Text Available In sporting horses the use of dietary polyunsaturated fatty acids (PUFAs could enhance performance because these fatty acids are very important in membrane permeability, and in particular they seem to increase the possibility of long chain fatty acids entering mythochondria to be burnt. The composition of cellular membranes and lipoprotein fatty acids com- position is strictly related to dietary fat quality; percentages of polyunsaturated fatty acids and amount of antioxidants also affect tissue susceptibility to lipid peroxidation. Six horses were used in a latin square design in which three homogeneous groups were subsequently assigned three dif- ferent dietary treatments for one month each: Control group (C: basic diet; Oil group (O: Basic diet + 200g/day oil rich in PUFAs (Crossential GLA TG20, Croda ®; Vitamin E group (O+E: basic diet + 200 g/day oil rich in PUFAs (Crossential GLA TG20, Croda ® + 5 g/day α-toco- pheryl-acetate (Egon-E, Acme ®. At the end of each experimental period blood samples were taken by jugular vein puncture. Serum oxidative status was evaluated by TBARs and d-ROMs assessment. Oxidative markers showed the high- est mean values for the oil group, even if no statistically significant differences were found.

    The ATLAS Pixel Detector is the innermost detector of the ATLAS experiment at the Large Hadron Collider at CERN. The detector provides hermetic coverage with three cylindrical layers and three layers of forward and backward pixel detectors. It consists of approximately 80 million pixels that are individually read out via chips bump-bonded to 1744 n-in-n silicon substrates. In this talk, results from the successful operation of the Pixel Detector at the LHC and its status after three years of operation will be presented, including monitoring, calibration procedures, timing optimization and detector performance. The record breaking instantaneous luminosities of 7.7 x 10^33 cm-2 s-1 recently surpassed at the Large Hadron Collider generate a rapidly increasing particle fluence in the ATLAS Pixel Detector. As the radiation dose accumulates, the first effects of radiation damage are now observable in the silicon sensors. A regular monitoring program has been conducted and reveals an increase in the silicon leakage ...

    Rubella in early pregnancy bears a high risk for congenital defects (e.g., cataracts, hearing loss, and heart disease) and for long-term sequelae in the newborn. Despite implementation of vaccination programs in many regions, the threat of devastating consequences from congenital rubella virus infection remains and careful screening of maternal immune status before and during pregnancy helps to reduce the risk. This study compared the performance of the Elecsys Rubella IgG assay with that of other assays routinely used for screening. Samples from 1,090 women undergoing routine antenatal care were tested using the Elecsys and Enzygnost Rubella IgG assays and the hemagglutination inhibition test. Samples with hemagglutination inhibition titers of 90.0%) than the other immunoassays (78.6 to 82.4%). The Elecsys assay reported significantly higher rubella virus IgG levels than the other immunoassays across the whole set of 1,090 samples, with the largest bias and deviation from limits of agreement in Bland-Altman analysis. In conclusion, the Elecsys assay is highly sensitive and specific with regard to qualitative results and suitable for routine automated screening. However, given the considerable variation between quantitative results from different immunoassays, testing methods should be documented and the same assay used throughout an individual's antenatal follow-up wherever possible.

    This study investigated the effects of cocoa butter and sunflower oil alone and in combination on performance, some biochemical parameters, immunoglobulin, and antioxidant vitamin status in Wistar rats. Forty-eight male rats were assigned to four groups, consisting of 12 rats with 3 replicates. Control received balanced rat diet without oil, cocoa butter group received 3.5% cocoa butter, sunflower oil group received 3.5% sunflower oil, the last group received 1.75% sunflower oil + 1.75% cocoa butter supplementation in the rat diet for 8 weeks. The total feed consumption in sunflower oil group was statistically lower than in the other groups. The serum creatinine level was decreased in cocoa butter group compared to control. Triglyceride and VLDL cholesterol levels were decreased in only sunflower oil and only cocoa butter groups as compared to control. The level of Ig M was statistically lower in cocoa butter and cocoa butter + sunflower oil groups than in control and sunflower oil groups. There were no statistically important difference in vitamin concentrations among trial groups. It was concluded that the supplementation of cocoa butter in diet decreased Ig M level, while the supplementation of cocoa butter and sunflower oil alone decreased the triglyceride and VLDL cholesterol levels.

    The present study investigated the neuroprotective mechanism of quercetin by assessing the biochemical and behavioral characteristics in rats sub-chronically treated with manganese alone at 15 mg/kg body weight or orally co-treated with quercetin at 10 and 20 mg/kg body weight for 45 consecutive days. Locomotor behavior was monitored using video-tracking software during a 10-min trial in a novel environment whereas the brain regions namely the hypothalamus, cerebrum and cerebellum of the rats were processed for biochemical analyses. Results indicated that co-treatment with quercetin significantly (p < 0.05) prevented manganese-induced locomotor and motor deficits specifically the decrease in total distance travelled, total body rotation, maximum speed, absolute turn angle as well as the increase in time of immobility and grooming. The improvement in the neurobehavioral performance of manganese-treated rats following quercetin co-treatment was confirmed by track and occupancy plot analyses. Moreover, quercetin assuaged manganese-induced decrease in antioxidant enzymes activities and the increase in acetylcholinesterase activity, hydrogen peroxide generation and lipid peroxidation levels in the hypothalamus, cerebrum and cerebellum of the rats. Taken together, quercetin mechanisms of ameliorating manganese-induced neurotoxicity is associated with restoration of acetylcholinesterase activity, augmentation of redox status and inhibition of lipid peroxidation in brain of rats.

    An experiment was conducted to evaluate the effect of stocking density on growth performance, carcass yield, and immune status of a local chicken breed. In total, 840 one-day-old male Suqin yellow chickens were placed into 4-m(2) cages in groups of 50 (low), 70 (medium), or 90 (high) birds. Each treatment was represented by 4 replicates (cages). The cages measured 2.84 × 1.42 m; half of the area of the cage (2 m(2)) was used from 1 to 28 d and the whole cage was used from 29 to 42 d. Stocking densities were 25, 35, and 45 birds/m(2) from 1 to 28 d and 12.5, 17.5, and 22.5 birds/m(2) from 29 to 42 d (low, medium, and high, respectively). Final production (live bird mass after fasting) per unit area was 14.46, 19.46, and 24.23 kg/m(2), respectively, at 42 d of age. Several immune parameters were evaluated, and the growth performance, carcass yield, and meat quality were determined. Body weight at 28 and 42 d of age was significantly reduced as the stocking density increased (P 0.05). The thigh yield of chickens in the medium-density group improved significantly (P 0.05) by the stocking density, but pH values increased slightly as density increased. No significant difference was noted in the immunological parameters, but the blood total protein and potassium were significantly affected by stocking density (P < 0.05). The findings of this study suggest that increasing the stocking density advantageously affected feed/gain and decreased the final BW, whereas no evidence was found that stocking density caused changes in any of the measured immune parameters.

    Pyrroloquinoline quinone (PQQ), a putative essential nutrient and redox modulator in microorganisms, cell and animal models, has been recognized as a growth promoter in rodents. Growth performance, carcass yield and antioxidant status were evaluated on broiler chickens fed different levels of PQQ disodium (PQQ.Na2). A total of 784 day-old male Arbor Acres (AA) broilers were randomly allotted into seven dietary groups: negative control group (NC) fed a basal diet without virginiamycin (VIR) or PQQ.Na2; a positive control group (PC) fed a diet with 15 mg of VIR/kg diet; and PQQ.Na2 groups fed with 0.05, 0.10, 0.20, 0.40 or 0.80 mg PQQ.Na2/kg diet. Each treatment contained eight replicates with 14 birds each. The feeding trial lasted for 6 weeks. The results showed that chicks fed 0.2 mg PQQ.Na2/kg diet significantly improved growth performance comparable to those in PC group, and the feed efficiency enhancement effects of dietary PQQ.Na2 was more apparent in grower phase. Dietary addition of PQQ.Na2 had the potential to stimulate immune organs development, and low level dietary addition (<0.1 mg/kg) increased plasma lysozyme level. Broilers fed 0.2 mg PQQ.Na2/kg diet gained more carcasses at day 42, and had lower lipid peroxide malondialdehyde content and higher total antioxidant power in plasma. The results indicated that dietary PQQ.Na2 (0.2 mg/kg diet) had the potential to act as a growth promoter comparable to antibiotic in broiler chicks.

    Shoulder trouble, described in the literature as "swimmer's shoulder," has been associated with competitive swimmers. The Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow Score is a validated survey used to define functional and performance measures of the upper extremity in overhead athletes. To date, no study has investigated the baseline functional scores for swimmers actively competing in the sport. To establish a baseline score for National Collegiate Athletic Association (NCAA) swimmers actively competing in the sport. Cross-sectional study; Level of evidence, 3. After institutional review board approval, the KJOC Shoulder and Elbow Score was administered to 5 NCAA swim teams (N = 99 participants; 46 men, 53 women). The results on 10 specific individual questions and on the total score were calculated according to the survey's original description. The mean scores were calculated for all participants. The Mann-Whitney U test was used to determine differences between sexes, years swimming, and self-reported injury status. The mean ± SD baseline KJOC score (out of a possible 100) for all participants was 79.0 ± 18.7; the mean score for men was 81.9 ± 15.6 and for women 76.6 ± 20.8. The score for athletes identifying themselves as injured at baseline was 53.9 ± 18.8, compared with 84.4 ± 13.6 for those not reporting as injured (P < .001). Athletes competing ≥11 years had a mean score of 72.0 ± 22.1; those competing ≤10 years scored 86.4 ± 11.4 (P = .007). Baseline scores for swimmers, which were lower than expected, were lower than baseline scores seen in studies of other overhead sports athletes. The data corroborate previous studies identifying swimmers as having a high level of shoulder trouble. Further research is indicated for improving shoulder symptoms and performance in competitive swimmers. © 2015 The Author(s).

    Mitchell, Mary A.

    This study analyzed English language learner (ELL) performance on the June 2012 Biology MCAS, namely on item attributes of domain, cognitive skill, and linguistic complexity. It examined the impact of English proficiency, Latinate first language, first language orthography, and late-entry ELL status. The results indicated that English proficiency was a strong predictor of performance and that ELLs at higher levels of English proficiency overwhelmingly passed. The results further indicated that English proficiency introduced a construct-irrelevant variance on the Biology MCAS and raised validity issues for using this assessment at lower levels of English proficiency. This study also found that ELLs with a Latinate first language consistently had statistically significant lower performance. Late-entry ELL status did not predict Biology MCAS performance.

    Objective The factors associated with persistent delirium, in contrast to resolved delirium, have not been studied well. The aim of our present study was to identify the factors associated with delirium resolution as measured by the Memorial Delirium Assessment Scale (MDAS) and functional improvement as measured by the Karnofsky Performance Status (KPS) scale. Method All subjects were recruited from psychiatric referrals at the Memorial Sloan Kettering Cancer Center (MSKCC). The two study instruments were performed at baseline (T1), at 2–3 days (T2), and at 4–7 days (T3). Subjects with persistent delirium were compared to those with resolved delirium in respect to sociodemographic and medical variables. Results Overall, 26 out of 111 patients had persistent delirium. These patients were older, predominantly male, and had more frequently preexisting comorbid dementia. Among cancer diagnoses and stage of illness, brain cancer and terminal illness contributed to persistent delirium or late response, whereas gastrointestinal cancer was associated with resolved delirium. Among etiologies, infection responded late to delirium management, usually at one week. Furthermore, delirium was more severe in patients with persistent delirium from baseline through one week. At baseline, MDAS scores were 20.1 in persistent delirium compared to 17 to 18.8 in resolved delirium (T2 and T3), and at one week of management (T3), MDAS scores were 15.2 and 4.7 to 7.4, respectively. At one week of management, persistent delirium manifested in more severe impairment in the domains of consciousness, cognition, organization, perception, psychomotor behavior, and sleep–wake cycle. In addition, persistent delirium caused more severe functional impairment. Significance of results In this delirium sample, advanced age and preexisting dementia, as well as brain cancer, terminal illness, infection, and delirium severity contributed to persistent delirium or late response, indicating a prolonged

    Full Text Available Helmy Haja Mydin, Stephen Murphy, Howell Clague, Kishore Sridharan, Ian K TaylorDepartment of Respiratory Medicine, Sunderland Royal Infirmary, Sunderland, United KingdomBackground: In patients with acute hypercapnic respiratory failure (AHRF during exacerbations of COPD, mortality can be high despite noninvasive ventilation (NIV. For some, AHRF is terminal and NIV is inappropriate. However there is no definitive method of identifying patients who are unlikely to survive. The aim of this study was to identify factors associated with inpatient mortality from AHRF with respiratory acidosis due to COPD.Methods: COPD patients presenting with AHRF and who were treated with NIV were studied prospectively. The forced expiratory volume in 1 second (FEV1, World Health Organization performance status (WHO-PS, clinical observations, a composite physiological score (Early Warning Score, routine hematology and biochemistry, and arterial blood gases prior to commencing NIV, were recorded.Results: In total, 65 patients were included for study, 29 males and 36 females, with a mean age of 71 ± 10.5 years. Inpatient mortality in the group was 33.8%. Mortality at 30 days and 12 months after admission were 38.5% and 58.5%, respectively. On univariate analysis, the variables associated with inpatient death were: WHO-PS ≥ 3, long-term oxygen therapy, anemia, diastolic blood pressure < 70 mmHg, Early Warning Score ≥ 3, severe acidosis (pH < 7.20, and serum albumin < 35 g/L. On multivariate analysis, only anemia and WHO-PS ≥ 3 were significant. The presence of both predicted 68% of inpatient deaths, with a specificity of 98%.Conclusion: WHO-PS ≥ 3 and anemia are prognostic factors in AHRF with respiratory acidosis due to COPD. A combination of the two provides a simple method of identifying patients unlikely to benefit from NIV.Keywords: acute exacerbations of COPD, noninvasive ventilation, emphysema, prognostic markers

    Full Text Available We evaluate the effect of the crude protein source (CP in combination with 2 feeding strategies (AL: ad libitum or R: restricted on the performance, health status and carcass traits of growing-fattening rabbits (between 33 and 75 d of age. Two experimental diets were formulated; the first containing soybean meal (SBM: 70 g/kg as the main CP source and the second containing white lupin seeds (WLS: 105 g/kg as the main CP source. A total of 160 weaned Hyplus rabbits (774±10 g live weight were randomly allocated to the experimental groups, combination of feeding strategy and diet (AL SBM, R SBM, AL WLS and R WLS; 40 rabbits per group with 4 rabbits per cage, for 42 d. The feeding programme was applied as follows: both the AL SBM and AL WLS rabbits were fed ad libitum for the entire fattening period, whereas the R SBM and R WLS rabbits were subjected to feed restriction between 33 and 47 d of age (75% of the ad libitum intake. Afterwards, all restricted rabbits were fed ad libitum until 75 d of age. Regardless of the CP source, the feed restriction reduced the final live weight by 83 g, chilled carcass weight by 65 g, and dressing out percentage by 0.9 percentage points (P<0.05. There was a higher chilled carcass weight (+114 g; P=0.001 and reference carcass weight (+91 g; P=0.001 in rabbits fed with WLS diet than in rabbits fed with SBM diet. No dead or morbid rabbits were observed in restricted rabbits during the restriction period. There was no effect of the diet on the health of rabbits. However when the rabbits of AL SBM and AL WLS group were compared did we observe a lower number of rabbits at sanitary risk in AL WLS group (2 vs. 12 rabbits, P=0.006. In conclusion, the growth performance was not affected by the crude protein source, and no interaction between dietary CP source and feeding regime was observed. Feed restriction regime did not improve sanitary risk index throughout the entire period.

    Purpose: In this retrospective study, we report on outcomes and prognostic factors for patients treated with stereotactic radiosurgery (SRS) for breast cancer brain metastases. Methods and Materials: We identified 132 consecutive patients with breast cancer who were treated with SRS for brain metastases from January 2000 through June 2010. We retrospectively reviewed records of the 51 patients with adequate follow-up data who received SRS as part of the initial management of their brain metastases. Overall survival (OS) and time to central nervous system (CNS) progression from the date of SRS were calculated using the Kaplan-Meier method. Prognostic factors were evaluated using the Cox proportional hazards model. Results: Triple negative subtype was associated with CNS progression on univariate analysis (hazard ratio [HR] = 5.0, p = 0.008). On multivariate analysis, triple negative subtype (HR = 8.6, p = 0.001), Luminal B subtype (HR = 4.3, p = 0.03), and omission of whole-brain radiation therapy (HR = 3.7, p = 0.02) were associated with CNS progression. With respect to OS, Karnofsky Performance Status (KPS) {<=} 80% (HR = 2.0, p = 0.04) and progressive extracranial disease (HR = 3.1, p = 0.002) were significant on univariate analysis; KPS {<=} 80% (HR = 4.1, p = 0.0004), progressive extracranial disease (HR = 6.4, p < 0.0001), and triple negative subtype (HR = 2.9, p = 0.04) were significant on multivariate analysis. Although median survival times were consistent with those predicted by the breast cancer-specific Graded Prognostic Assessment (Breast-GPA) score, the addition of extracranial disease status further separated patient outcomes. Conclusions: Tumor subtype is associated with risk of CNS progression after SRS for breast cancer brain metastases. In addition to tumor subtype and KPS, which are incorporated into the Breast-GPA, progressive extracranial disease may be an important prognostic factor for OS.

    Full Text Available BACKGROUND: Nutrition is one of many factors affecting the cognitive development of children. In Cambodia, 55% of children <5 y were anemic and 40% stunted in 2010. Currently, no data exists on the nutritional status of Cambodian school-aged children, or on how malnutrition potentially affects their cognitive development. OBJECTIVE: To assess the anthropometric and micronutrient status (iron, vitamin A, zinc, iodine of Cambodian schoolchildren and their associations with cognitive performance. METHODS: School children aged 6-16 y (n = 2443 from 20 primary schools in Cambodia were recruited. Anthropometry, hemoglobin, serum ferritin, transferrin receptors, retinol-binding protein and zinc concentrations, inflammation status, urinary iodine concentration and parasite infection were measured. Socio-economic data were collected in a sub-group of children (n = 616. Cognitive performance was assessed using Raven's Colored Progressive Matrices (RCPM and block design and picture completion, two standardized tests from the Wechsler Intelligence Scale for Children (WISC-III. RESULTS: The prevalence of anemia, iron, zinc, iodine and vitamin A deficiency were 15.7%; 51.2%, 92.8%, 17.3% and 0.7% respectively. The prevalence of stunting was 40.0%, including 10.9% of severe stunting. Stunted children scored significantly lower than non-stunted children on all tests. In RCPM test, boys with iron-deficiency anemia had lower scores than boys with normal iron status (-1.46, p<0.05. In picture completion test, children with normal iron status tended to score higher than iron-deficient children with anemia (-0.81; p = 0.067 or without anemia (-0.49; p = 0.064. Parasite infection was associated with an increase in risk of scoring below the median value in block design test (OR = 1.62; p<0.05, and with lower scores in other tests, for girls only (both p<0.05. CONCLUSION: Poor cognitive performance of Cambodian school-children was multifactorial and

    The use of gemcitabine and oxaliplatin is well documented in selected patients with advanced biliary tract carcinoma (BTC), but little is known on the feasibility of systemic treatments in patients with a performance status (PS) of 2. We retrospectively examined the medical records of consecutive BTC patients with a PS of 2 receiving gemcitabine 1000 mg/m(2) plus oxaliplatin 100 mg/m(2) every 2 weeks from January 2003 to December 2011 in our institution. Body composition was analysed by computed tomography scan to detect sarcopenia. The primary evaluation criterion was safety. The secondary evaluation criteria were the response rate, progression-free survival (PFS) and overall survival (OS). Twenty-eight patients (median age: 63 years, range 41-83) received a total of 175 cycles (median per patient: 6, range 2-12). Ten patients (35.7%) had sarcopenia on the pretreatment computed tomography scan. The most frequent toxicities were thrombocytopenia (grades 2-4: n=4, 14.3%), peripheral neuropathy (grades 2-3: n=9, 32.1%) and cholangitis (n=4, 14.3%). The best response was a partial response in 10.7% of patients [95% confidence interval (CI): 0-22.2] and stable disease in 42.9% of patients. The median PFS and OS were 4.6 (95% CI: 2.5-6.3) and 7.5 (95% CI: 5.2-9.5) months, respectively. The median PFS and OS were significantly longer in patients without sarcopenia: 7.0 months (95% CI: 4.4-8.0) vs. 2.2 months (95% CI: 2.0-2.5), P less than 0.01, and 10.4 months (95% CI: 7.5-11.6) vs. 4.9 months (95% CI: 3.7-5.2), P less than 0.01, respectively. In our experience, gemcitabine-oxaliplatin was feasible and induced effective palliation in PS2 patients with advanced BTC. Further studies are warranted to confirm these findings.

    We examined the current status of specialized agencies for occupational health management (SAs) and their workforce. Furthermore, we aimed to clarify the current practice status of SA healthcare professionals and factors that influence their performance. To examine the current SA workforce, we analyzed data from the 2014 Survey of Current Status of SA and their Workforce from the Ministry of Employment and Labor (MOEL). Furthermore, we mailed out an original questionnaire to SA professionals to determine their current health management status and factors that affect their performance. Data from the respondents (N = 384) were analyzed. In 2014, the workforce performing health management in SAs comprised 232 physicians, 507 nurses, and 312 occupational hygienists, with no significant regional differences in the distribution of physicians and nurses. According to the findings of the questionnaire, the average daily number of worker consultations by physicians and nurses was 22.8, while the average time taken for health management ranged from 74.3 to 104.3 min, depending on the size of the firm. Most of the respondents (41.5%) answered that they were following-up on more than 80% of individuals with illnesses. Among health management tasks, performance scores of "consultations for general diseases" and "consultations for lifestyle habits" were relatively high, whereas health promotion activities at workplaces were relatively low. There was a significant correlation between the utilization of general and special health examination results and task performance. Among health management tasks, follow-up management of individuals with illnesses and consultations for disease/lifestyle habits were relatively well performed, whereas health promotion activities at workplaces were not performed well. Among factors that positively influenced SA performance at workplaces, only the utilization of health examination results had significant effects. Therefore, to accomplish

    When patients with small cell lung cancer (SCLC) experience locoregional recurrence, surgery is often not employed as salvage therapy. Systemic chemotherapy and radiotherapy are often used. Many radiation oncologists are reluctant to deliver a second course of radiotherapy. However, select patients may benefit from re-irradiation. This study aimed to identify these patients. In patients receiving re-irradiation for a locoregional recurrence of SCLC, 11 potential prognostic factors were analyzed for survival. Survival was positively associated with a Karnofsky performance score ≥80 (p=0.003) and a cumulative dose >90 Gy (p=0.026). A trend was observed for younger age, longer interval between first course of radiotherapy and re-irradiation, a greater dose of re-irradiation and for concurrent chemotherapy. Significant predictors of survival in patients re-irradiated for a locoregional recurrence of SCLC were identified. Patients with a good performance status can benefit from re-irradiation if administered in sufficient doses. Copyright© 2016 International Institute of Anticancer Research (Dr. John G.

    Pemetrexed plus carboplatin offers survival advantage in first line treatment of advanced lung cancer patients with performance status of 2. We estimated the cost-effectiveness of this combined regimen compared to pemetrexed alone in a Brazilian population. A cost-effectiveness analysis was conducted based on a randomized phase III trial in patients with advanced non-small cell lung cancer (NSCLC) and ECOG performance status of 2 (PS2), comparing doublet regimen pemetrexed plus carboplatin with pemetrexed alone. The perspective adopted was the public health care sector over a three-year period. Direct medical costs and survival time were calculated from patient-level data and utility values were extracted from the literature. Sensitivity analyses were performed to evaluate uncertainties in the results. The combined regimen pemetrexed plus carboplatin yielded a gain of 0.16 life year (LY) and 0.12 quality-adjusted life year (QALY) compared to pemetrexed alone. The total cost was 17,674.31 USD for the combined regimen and 15,722.39 USD for pemetrexed alone. The incremental cost-effectiveness ratio (ICER) was $12,016.09 per LY gained and $15,732.05 per QALY gained. The factors with the greatest impact on the ICER are pemetrexed price and the time to progression utility value. The cost-effectiveness acceptability curve showed an upper 90% probability of pemetrexed plus carboplatin being cost-effective with a threshold between two and three GDP per capita. Our study suggests superiority of the combined pemetrexed plus carboplatin regimen in terms of efficacy as well as cost-effectiveness in advanced NSCLC patients with a poor performance status of 2.

    2017-06-01

    This paper argues that shifts in access to housing - both in relation to rental and ownership - disrupt middle-class reproduction in ways that fundamentally influence class formation. While property ownership has had a long association with middle-class identities, status and distinction, an increasingly competitive rental market alongside inflated property prices has impacted on expectations and anxieties over housing futures. In this paper, we consider two key questions: (1) What happens to middle-class identities under the conditions of this wider structural change? (2) How do the middle classes variously manoeuvre within this? Drawing on empirical research conducted in London, we demonstrate that becoming an owner-occupier may be fractured along lines of class but also along the axes of age, wealth and timing, particularly as this relates to the housing market. It builds on understandings of residential status and place as central to the formation of class, orienting this around the recognition of both people and place as mutable, emphasizing that changing economic and social processes generate new class positionalities and strategies for class reproduction. We argue that these processes are writ large in practices of belonging and claims to place, with wider repercussions within the urban landscape. © London School of Economics and Political Science 2017.

    Acute generalized peritonitis secondary to complicated diverticulitis is a life-threatening condition; the standard treatment is surgery. Despite advances in peri-operative care, this condition is accompanied by a high peri-operative complication rate (22%-25%). No definitive evidence is available to recommend a preferred surgical technique in patients with Hinchey stage III/IV disease. A matched case-control study enrolling patients from four surgical units at Italian university hospital was planned to assess the most appropriate surgical treatment on the basis of patient performance status and peritonitis exposure, with the aim of minimizing the surgical site infection (SSI). A series of 1,175 patients undergoing surgery for Hinchey III/IV peritonitis in 2003-2013 were analyzed. Cases (n=145) were selected from among those patients who developed an SSI. control ratio was 1:3. Cases and control groups were matched by age, gender, body mass index, and Hinchey grade. We considered three surgical techniques: T1=Hartman's procedure; T2=sigmoid resection, anastomosis, and ileostomy; and T3=sigmoid resection and anastomosis. Six scoring systems were analyzed to assess performance status; subsequently, patients were divided into low, mild, and high risk (LR, MR, HR) according to the system producing the highest area under the curve. We classified peritonitis exposition as P1=24 h. Univariable and multivariable analyses were performed. The Apgar scoring system defined the risk groups according to performance status. Lowest SSI risk was expected when applying T3 in P1 (OR=0.22), P2 (OR=0.5) for LR and in P1 (OR=0.63) for MR; T2 in P2 (OR=0.5) in LR and in P1 (OR=0.61) in MR; T1 in P3 (OR=0.56) in LR; in P2 (OR=0.63) and P3 (OR=0.54) in MR patients, and in each P subgroup (OR=0.93;0.97;1.01) in HR. Pre-operative assessment based on Apgar scoring system integrated with peritonitis exposure in complicated diverticulitis may offer a ready-to-use tool for reducing SSI

    We propose a novel high performance radiation detector and imaging sensor by a ground-breaking core-shell diode array design. This novel core-shell diode array are expected to have superior performance respect to ultrahigh radiation hardness, high sensitivity, low power consumption, fast signal response and high spatial resolution simultaneously. These properties are highly desired in fundamental research such as high energy physics (HEP) at CERN, astronomy and future x-ray based protein crystallography at x-ray free electron laser (XFEL) etc.. This kind of detectors will provide solutions for these fundamental research fields currently limited by instrumentations. In this work, we report our progress on the development of core-shell diode array for the applications as high performance imaging sensors and particle detectors. We mainly present our results in the preparation of high aspect ratio regular silicon rods by metal assisted wet chemical etching technique. Nearly 200 μm deep and 2 μm width channels with high aspect ratio have been etched into silicon. This result will open many applications not only for the core-shell diode array, but also for a high density integration of 3D microelectronics devices.

    In advanced cancer patients, the oxidative stress could take place either at the onset of disease or as a function of disease progression. To test this hypothesis, the following parameters were investigated: the erythrocyte activity of the enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPx), the serum activity of glutathione reductase (GR) and the serum total antioxidant status (TAS). The total antioxidant capacity of plasma LMWA was evaluated by the cyclic voltammetry methodology. We further determined the serum levels of proinflammatory cytokines (IL-6 and TNFalpha), IL-2, leptin and C-reactive protein (CRP). All of these parameters have been correlated with the most important clinical indices of patients such as Stage of disease, ECOG PS and clinical response. Eighty-two advanced stage cancer patients and 36 healthy individuals used as controls were included in the study. Our findings show that SOD activity was significantly higher in cancer patients than in controls and GPx activity was significantly lower in cancer patients than in controls. Serum values of IL-6, TNFalpha and CRP were significantly higher in patients than in controls. Serum leptin values of cancer patients were significantly lower than controls. SOD activity increased significantly from Stage II/ECOG 0-1 to Stage IV/ECOG 0-1, whereas it decreased significantly in Stage IV/ECOG 3. GPx activity decreased significantly in Stage IV/ECOG 2-3. An inverse correlation between ECOG PS and serum leptin levels was found. Serum levels of IL-2 decreased from Stage II/ECOG 0-1 to Stage IV/ECOG 2-3. A direct correlation between Stage/ECOG PS and serum levels of both IL-6 and CRP was observed. Cisplatin administration induced a significant increase of GPx after 24 hr. In conclusion, this is the first study that shows that several "biological" parameters of cancer patients such as antioxidant enzyme activity, cytokines, leptin and CRP strictly correlate with the most important clinical

    The present study was carried out to investigate the effects of dietary supplementation of chromium-methionine (CrMet) and vitamin C (VC) on performance, immune response, and stress status of laying hens subjected to high stocking density. A total of 360 Hy-Line W-36 leghorn hens (at 26 wk old) were used in a 2×3×2 factorial arrangement that had 2 cage densities (5 and 7 hens per cage), 3 Cr levels (0, 500, and 1,000 ppb as CrMet), and 2 dietary VC levels (0 and 500 ppm as L-ascorbic acid). The trial lasted for 12 wk. The first 2 wk were for adaptation (26 to 28 wk of age), and the remaining 10 wk served as the main recording period. In addition to performance, immune response to Newcastle disease virus (NDV) was assessed at d 7 and 14 postvaccination. Also, the birds' stress status was evaluated by analyzing appropriate plasma metabolites. The results showed that hens in cages with higher stocking density had lower hen-day egg production, egg mass, and feed intake compared with those in normal density cages (Phens kept at a density of 7 hens/cage were significantly higher than those of hens in normal cage density (Phens. While high stocking density caused a marked increase in plasma corticosterone (Phens. The high stocking density challenge suppressed NDV antibody response (Phens kept at a density of 7 hens/cage (P<0.01). From the present observations, it can be concluded that CrMet can improve laying performance largely because it alleviates harmful responses to stressful conditions.

    An experiment was conducted in weanling pigs (Landrace x Yorkshire x Duroc) to evaluate the effects of dietary iron levels on growth performance, hematological status, liver mineral concentration, fecal microflora, and diarrhea incidence. One hundred and forty-four piglets (initial BW 5.96 +/- 0.93 kg) were randomly allotted to one of the four dietary treatments on the basis of their body weights. The basal diets for each phase (phase 1: days 0 to 14; phase 2: days 15 to 28) were formulated to contain minimal Fe and then supplemented with gradient levels of Fe (0, 50, 100, and 250 mg/kg) from ferrous sulfate. Feces were collected on days 14 and 28 and used for the analysis of microbial count and trace minerals. Eight piglets from each treatment (two piglets per pen) were bled at 0, 7, 14, 21, and 28 days to determine their hematological and plasma Fe status.

The possible relationship between the biochemical and behavioral parameters was evaluated.Methods: Aged rats were treated (for 36 days with rivastigmine (0.3 mg/kg rat/day ip, selegiline (0.25 mg/kg rat/day im, rivastigmine plus selegiline in the same doses and way of administration as separately. Aged and adult control groups received NaCl 0.9% 0.5 ml ip.Results: TAS was lower in aged than in adult rats, rivastigmine alone does not affect TAS, decreases AChE activity, increases (Na+, K+-ATPase and Mg2+-ATPase activity of aged rat brain and improves cognitive performance. Selegiline alone decreases free radical production and increases AChE activity and (Na+, K+-ATPase activity, improving cognitive performance as well. In the combination: rivastigmine seems to cancel selegiline action on TAS and AChE activity, while it has additive effect on (Na+, K+-ATPase activity. In the case of Mg2+-ATPase selegiline appears to attenuate rivastigmine activity. No statistically significant difference was observed in the cognitive performance.Conclusion: Reduced TAS, AChE activity and learning performance was observed in old rats. Both rivastigmine and selesiline alone improved performance, although they influenced the biochemical parameters in a different way. The combination of the two drugs did not affect learning performance.Keywords: aged rat, brain enzymes, TAS, learning, rivastigmine

    The objective of this study was to compare the effects of Aspergillus niger-fermented pine needles and nonfermented pine needles on growth performance and antioxidant capacity in broiler chicks. In total, 300 1-day-old broiler chicks were randomly allocated to 5 dietary treatments, which were then denoted as the control treatment (basal diet); the nonfermented treatment (containing 0.3% and 0.6% nonfermented treatment, respectively, in the starter and grower phase); or the fermented 1, fermented 2, or fermented 3 treatments. The fermented 1, fermented 2, and fermented 3 treatments contained 0.1, 0.3, and 0.5% fermented treatment, respectively, in the starter phase and 0.2, 0.6, and 1.0% fermented treatment, respectively, in the growth phase for 42 d. The results showed that fermentation treated supplementation had no adverse effect on the growth performance of broilers at 42 d of age. The activity of total nitric oxide synthase was significantly (P<0.05) decreased in the fermented treatment compared with the control and nonfermented treatments in broilers at 21 d of age. Compared with the control, broilers had higher (P<0.05) total superoxide dismutase activities and total antioxidant capacity when they were provided with either the fermented 2 or fermented 3 diet. The malondialdehyde content was significantly (P<0.05) decreased in the fermented 2 and fermented 3 treatments compared with the control and nonfermented treatments. It was concluded that the addition of fermented treatment to the diet could improve antioxidant capacity in broilers, as evidenced by the decrease in malondialdehyde and the increase in total superoxide dismutase activities; however, the effect of fermentation treatment on growth performance was negligible.

    This section of the Joint summary technical letter report (TLR) describes work conducted at the Pacific Northwest National Laboratory (PNNL) during FY 2016 (FY16) on the under-sodium viewing (USV) PNNL project 58745, work package AT-16PN230102. This section of the TLR satisfies PNNL’s M3AT-16PN2301025 milestone and is focused on summarizing the design, development, and evaluation of two different phased-array ultrasonic testing (PA-UT) probe designs—a two-dimensional (2D) matrix phased-array probe, and two one-dimensional (1D) linear array probes, referred to as serial number 4 (SN4) engineering test units (ETUs). The 2D probe is a pulse-echo (PE), 32×2, 64-element matrix phased-array ETU. The 1D probes are 32×1 element linear array ETUs. This TLR also provides the results from a performance demonstration (PD) of in-sodium target detection trials at 260°C using both probe designs. This effort continues the iterative evolution supporting the longer term goal of producing and demonstrating a pre-manufacturing prototype ultrasonic probe that possesses the fundamental performance characteristics necessary to enable the development of a high-temperature sodium-cooled fast reactor (SFR) inspection system for in-sodium detection and imaging.

    The development of sustainable nuclear energy requires R and D on fuel and material behaviour under irradiation with a high level of performance in order to meet the needs and challenges for the benefit of industry, research and public bodies. These stakes require a sustainable and secured access to an up-to-date high performance Material Testing Reactor. Following a broad survey within the European Research Area, the international community agreed that the need for Material Test Reactors in support of nuclear power plant safety and operation will continue in the context of sustainable nuclear energy. The Jules Horowitz Reactor project (JHR) copes with this context. JHR is designed as a user facility addressing the needs of the international community. This means: - flexibility with irradiation loops able to reproduce a large variation in operation conditions of different power reactor technologies, - high flux capacity to address Generations II, III, and IV needs. JHR is designed, built and operated as an international user facility because: - Given the maturity and globalization of the industry, domestic tools have no more the required level of economic and technical efficiency. Meanwhile, countries with nuclear energy need an access to high performance irradiation experimental capabilities to support technical skill and guarantee the competitiveness and safety of nuclear energy. - Many research items related to safety or public policy (waste management, etc.) require international cooperation to share costs and benefits of resulting consensus. JHR design is optimised for offering high performance material and fuel irradiation capability for the coming decades. This project is driven and funded by an international consortium gathering vendors, utilities and public stakeholders. This consortium has been set up in March 2007 when the construction began. The construction is in progress and the start of operation is scheduled for 2014. The JHR is a research

    The aim of this study was to investigate the effect of Bacillus subtilis var. natto N21 (BAC) and Saccharomyces cerevisiae Y10 (SAC) fermented liquid feed (FLF) during different incubation times on the growth performance, relative organ weight, intestinal microflora, and organ antioxidative status in Landes geese. Two hundred forty male Landes geese (10 wk old) with the BW of 4.163 ± 0.108 kg were selected for a 3-wk trial and randomly allotted to 3 treatments according to their BW (10 replicates/treatment and 8 geese/replicate). The treatments included 1) CON, dry basal feed (corn-soybean basal diet mixed with water) before feeding (2:1 wt/wt), 2) FLF24, 24 h FLF, and 3) FLF48, 48 h FLF. The FLF diet was prepared by storing basal diet with 10(9) cfu/g feed of each BAC and SAC and water (2:1 wt/wt) in a closed tank at 20°C fermented for 24 or 48 h. The BW gain and feed intake of geese fed FLF24 and FLF48 was greater (P Feeding geese with FLF24 and FLF48 feeds increased (P feeding geese with BAC and SAC mix FLF can improve growth and feed intake, modulate the intestine ecology, and decrease the blood cholesterol concentrations; it also can improve the antioxidative status of organs and breast muscle.

    The study was designed to evaluate the effects of different dietary levels of rice bran (RB) in laying duck diets on performance, egg quality, oxidation status, egg yolk fatty acid composition, and hepatic expression of fatty acid metabolism-related genes. Longyan females (1080) with similar BW at 19 wk of age were randomly assigned to 6 dietary treatments, each consisting of 6 replicates of 30 birds. The basal diet (I) was a typical corn-soybean ration while the experimental diets (II to VI) substituted RB for corn and wheat bran and a small reduction of soybean meal. The level of substitution in diets (II to VI) was 6%, 12%, 18%, 24%, and 30%, respectively. The experiment lasted for 12 wks. Average egg weight and daily egg mass decreased linearly as the level of RB inclusion increased (Pegg yolk linearly decreased with increasing RB, and many of the key polyunsaturated fatty acids (PUFA), like C18:2 n-6 and C18:3 n-3, linearly increased (Pegg yolk cholesterol or triglyceride content (P>0.05). In conclusion, the current study suggests that ducks from 19 to 31 wk could be fed diets with up to about 18% RB without effect on the number of eggs produced, egg quality, and oxidative status. Increasing amounts of RB linearly increased egg yolk concentrations of key fatty acids like C18:2 n-6 and C18:3 n-3 and decreased the hepatic abundance of FAS and SREBP-1 transcripts.

    This cluster-randomized trial was designed to determine the efficacy of a 6-month exercise-nutritional supplement program (ENP) on physical function and nutritional status for older adults and the feasibility of implementing this program in a senior living setting. Twenty senior living facilities were randomized to either a three day per week group-based ENP led by a trained facility staff member or a health education program (SAP). Participants (N=121) completed a short physical performance battery, 400 meter walk, handgrip strength test, and mini-nutrition assessment. 25-hydroxyvitamin D [25(OH)D], Insulin-like growth-factor 1 (IGF-1) and activity level were also measured. The ENP did not significantly improve physical function or nutritional status compared with the SAP. Compared with baseline, participants in the ENP engaged in 39 minutes less physical activity per week at 6-months. Several facility characteristics hindered implementation of the ENP. This study highlights the complexity of implementing an evidence-based program in a field setting.

    The ATLAS Pixel Detector is the innermost detector of the ATLAS experi- ment at the Large Hadron Collider at CERN, providing high-resolution mea- surements of charged particle tracks in the high radiation environment close to the collision region. The detector provides hermetic coverage with three cylindrical layers and three layers of forward and backward pixel detectors. It consists of approximately 80 million pixels that are individually read out via chips bump-bonded to 1744 n-in-n silicon substrates. After three years of operation the detector performance is excellent: 96% of the pixels are opera- tional, at 3500 e threshold noise occupancy and efficiency exceed the design specification. The effect of radiation on the silicon sensor is measured and compared with model of radiation damage.

    The ATLAS experiment is designed to study the proton-proton collisions produced at the Large Hadron Collider (LHC) at CERN. Its calorimeter system measures the energy and direction of final state particles with pseudo rapidity $|eta| < 4.9$. Accurate identification and measurement of the characteristics of electromagnetic objects (electrons/photons) are performed by liquid argon (LAr)-lead sampling calorimeters in the region $|eta| < 3.2$, using an innovative accordion geometry that provides a fast, uniform azimuthal response without gaps. The hadronic calorimeters measure the properties of hadrons, jets, and tau leptons, and also contribute to the measurement of the missing transverse energy and identification of muons. This is done in the region $|eta| < 1.7$ with a scintillator-steel sampling calorimeter, and in the region $1.4 < |eta| < 3.2$ with a copper-LAr sampling calorimeter. The coverage is extended to $|eta| < 4.9$ by an integrated forward calorimeter (FCal...

    Leptin is a pleiotropic hormone associated with learning and memory via brain receptors. However, elevated plasma leptin levels may impair cognitive and memory functions. Since individual differences in memory performance affect students' ability to learn, we aimed to study the relation between leptin status in adolescence and school performance. We studied 568 adolescents aged 16-17 years from Santiago. A cross-sectional analysis was carried out on a birth cohort conducted in Santiago (Chile). We measured serum leptin concentration using an enzyme-linked immunosorbent assay. Cut-offs from the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) Study for 16-year-olds were used to define abnormally high leptin levels (hyperleptinaemia). Academic performance was measured using high-school grades and grade point average (GPA). Data were collected in 2009-2012; data analysis was performed in 2014. 15% of participants had hyperleptinaemia. They had significantly lower school grades and GPA compared with participants with normal leptin levels (eg, GPA mean difference=33.8 points). Leptin levels were negative and significantly correlated with school grades in 9th, 10th and 12th. Similarly, it was negatively correlated with high-school GPA. After controlling for health, sociodemographic and education confounders, the chances of having a performance ≥75th centile in students having hyperleptinaemia were 32% (95% CI 0.19% to 0.89%) that of students having normal serum leptin concentration. In high school students, abnormally high levels of leptin were associated with poorer academic performance. These findings support the idea of a relationship between leptin and cognition. Further research is needed on the cognitive effects of leptin in younger populations. Published by the BMJ Publishing Group Limited.

    This study investigated the effects of a sport nutrition education intervention (SNEI) on dietary intake, knowledge, body composition, and performance in NCAA Division I baseball players. Resistance trained NCAA Division I baseball players (82.4 ± 8.2 kg; 1.83 ± 0.06 m; 13.7 ± 5 % body fat) participated in the study during 12 weeks of off-season training. Fifteen players volunteered for SNEI while 15 players matched for position served as controls (C) for body composition and performance. The nutrition intervention group (NI) received a 90 min SNEI encompassing energy intake (Kcal), carbohydrate (CHO), protein (PRO), fat, food sources, and hydration. Sport nutrition knowledge questionnaires were administered to NI pre and post. Nutritional status was determined by three-day dietary logs administered to NI pre and post. Body composition and performance (5-10-5 shuttle test, vertical jump, broad jump, 1 RM squat) were measured pre and post for C and NI. Knowledge increased in NI. Pro and fat, but not CHO intake increased in NI. FM decreased pre to post in NI (11.5 ± 4.8 vs. 10.5 ± 5.4 kg) but not C (11.3 ± 4.7 vs. 11.9 ± 4.5 kg). FFM increased pre to post with no differences between groups. The 5-10-5 shuttle times decreased significantly more in NI (4.58 ± 0.15 vs. 4.43 ± 0.13 sec) compared to C (4.56 ± 0.18 vs. 4.50 ± 0.16 sec). Jump and squat performance increased pre to post with no differences between groups. Our findings indicate that an off season SNEI is effective at improving sport nutrition knowledge and some, but not all, nutrient intakes and performance measures in Division I baseball players. Key points Sport nutrition education intervention increased nutritional knowledge and nutritional status. Sport nutrition education intervention reduced body fat percentage, total fat mass, 5-10-5 shuttle times, and trended towards greater increases in lean mass compared to controls. Both groups increased strength and jump ability similarly. PMID:28344452

    Performance-based incentives (PBIs) aim to counteract weak providers' performance in health systems of many developing countries by providing rewards that are directly linked to better health outcomes for mothers and their newborns. Translating funding into better health requires many actions by a large number of people. The actions span from community to the national level. While different forms of PBIs are being implemented in a number of countries to improve health outcomes, there has not been a systematic review of the evidence of their impact on the health of mothers and newborns. This paper analyzes and synthesizes the available evidence from published studies on the impact of supply-side PBIs on the quantity and quality of health services for mothers and newborns. This paper reviews evidence from published and grey literature that spans PBI for public-sector facilities, PBI in social insurance reforms, and PBI in NGO contracting. Some initiatives focus on safe deliveries, and others reward a broader package of results that include deliveries. The Evidence Review Team that focused on supply-side incentives for the US Government Evidence Summit on Enhancing Provision and Use of Maternal Health Services through Financial Incentives, reviewed published research reports and papers and added studies from additional grey literature that were deemed relevant. After collecting and reviewing 17 documents, nine studies were included in this review, three of which used before-after designs; four included comparison or control groups; one applied econometric methods to a five-year time series; and one reported results from a large-scale impact evaluation with randomly-assigned intervention and control facilities. The available evidence suggests that incentives that reward providers for institutional deliveries result in an increase in the number of institutional deliveries. There is some evidence that the content of antenatal care can improve with PBI. We found no direct

    The aim of this experiment was to investigate the effect of n-3 fatty acid (FA) supplemented diets on breeder performance, productivity and egg quality. Breeders (n = 480) were fed the supplemented diet from 18 weeks onwards; the inclusion level of n-3 FA was increased from 1.5% to 3.0% from 34 weeks of age onwards until 48 weeks of age. Ross-308 broiler breeders (n = 480) were fed one of four different diets: a basal diet rich in n-6 FA (control diet) or one of three diets rich in n-3 FA. For the n-3 FA diets, eicosapentaenoic acid (EPA, 20:5 n-3) and docosahexaenoic acid (DHA, 22:6 n-3) were fed to the broiler breeders at different ratios formulated to obtain EPA/DHA ratios of 1/1, 1/2 or 2/1. Differences in performance, reproduction and egg quality parameters due to n-3 supplementation were noted more for the 1.5% followed by the 3.0% fed broilers than their 1.5% supplemented counterparts. Egg weight (p n-3 FA (at 3.0% inclusion level) fed broilers compared to the control group. For the EPA- and DHA-fed breeders, a higher proportional abdominal fat percentage (p = 0.025) and proportional albumen weight (%) (p = 0.041) were found respectively. Dietary treatments did not affect reproduction. It can be concluded that the results of the present experiment indicate no significant differences between treatments at 1.5% inclusion levels. However, increasing this level to 3.0% is not recommended due to the rather negative effects on the measured parameters. It should be further investigated whether these adverse effects were obtained due to (i) the higher supplementation level, (ii) combining a supplementation level of 1.5% with 3% or (iii) the duration of supplementation.

    The effects of supplementing lambs with Co, either alone or in combination with vitamin B and Se, were evaluated over the period from weaning to selection for slaughter. Two hundred and five recently weaned (at 14 wk [SD 0.44] of age), spring-born lambs of various crossbred genotypes were stratified, within genotype, by BW and gender and allocated to 3 groups, which were then allocated at random to one of the following treatments: no supplement (Control), a supplement containing Co only (Co-only), or a supplement containing Co, vitamin B, and Se (VitMin). The concentration of Co in the Co-only supplement was 2.1 mg/mL (as cobalt sulfate); the VitMin supplement contained Co (10 mg/mL, as cobalt acetate), vitamin B (200 μg/mL), and Se (0.25 mg/mL, as sodium selenite). Lambs on the Co-only and VitMin treatments received, every 14 d, 10 and 2.1 mL, respectively, of oral drench. Lambs were managed in a rotational-grazing system from 12 July (swards predominantly ) and selected for slaughter, on the basis of BW, after 45, 73, or 115 d; all remaining lambs were slaughtered on d 157. Supplementation, with Co-only or VitMin, increased BW at slaughter ( 0.05) between the Co-only and the VitMin treatments for ADG, carcass weight, fat score, or dressing percentage. Supplementation with Co increased liver Co concentration ( < 0.001), and lambs supplemented with VitMin had greater liver Co concentration than lambs supplemented with Co-only ( < 0.05); the concentrations were 0.18, 0.85, and 1.18 μmol/L for the Control, Co-only, and VitMin treatments, respectively. Treatment had no effect ( = 0.65) on the concentration of Se in kidney tissue. It is concluded that supplementation with Co increased lamb performance after weaning, that response to supplementation increased as the grazing season progressed, and that no extra benefit in performance resulted from augmenting supplementary Co with B and Se.

    This study aimed to evaluate the effects of feeding glycerol-enriched yeast culture (GY) on feed intake, lactation performance, blood metabolites, and expression of some key hepatic gluconeogenic enzymes in dairy cows during the transition period. Forty-four multiparous transition Holstein cows were blocked by parity, previous 305-d mature equivalent milk yield, and expected calving date and randomly allocated to 4 dietary treatments: Control (no additive), 2 L/d of GY (75.8 g/L glycerol and 15.3 g/L yeast), 150 g/d of glycerol (G; 0.998 g/g glycerol), and 1 L/d of yeast culture (Y; 31.1 g/L yeast). All additives were top-dressed and hand mixed into the upper one-third of the total mixed ration in the morning from -14 to +28 d relative to calving. Results indicated that the DMI, NE intake, change of BCS, and milk yields were not affected by the treatments ( > 0.05). Supplementation of GY or Y increased milk fat percentages, milk protein percentages, and milk protein yields relative to the Control or G group ( 0.10). In conclusion, dietary GY or Y supplementation increased the milk fat and protein content of the cows in early lactation and GY or G supplementation improved the energy status as indicated by greater plasma glucose and lower plasma BHBA and NEFA concentrations and upregulated the hepatic gluconeogenic enzymes of dairy cows during the transition period. Feeding cows with a GY mixture in the peripartum period combined the effects of yeast on lactation performance and the effects of glycerol on energy status in dairy cows.

    Full Text Available The objective was to study the effects of partial replacement of soybean meal (SBM with xylose-treated SBM (XSBM as a source of rumen undegradable protein (RUP in the starter concentrate of calves on performance, health status and selected blood metabolites. Twenty-one female Holstein dairy calves (body weight=39.6±2.3 kg were randomly assigned to 3 groups (n=7 each: i starter concentrate with 25% SBM [control (CTR]; ii starter concentrate with 17.5% SBM +7.5% XSBM (7.5XSBM; and iii starter concentrate with 12.5% SBM+12.5% XSBM (12.5XSBM. Calves received 2 L of milk twice daily, with ad libitum access to starter concentrates from d 4 until weaning (d 56. Performance and health status were recorded throughout the experiment. Blood samples collected on d 4, 35 and 56 were assayed for concentrations of glucose, total protein (TP, and plasma urea nitrogen (PUN. Starter intake (560, 400, and 420 g/d for CTR, 7.5XSBM, and 12.5XSBM, respectively, average daily gain (0.67, 0.6 and 0.57 kg/d, and feed to gain ratio (0.83, 0.67, and 0.74 were affected by treatments (P<0.05. Hearth girth, height at withers, body length, rectal temperature, faecal score, and respiratory score did not differ among treatments. Mean plasma glucose and TP were not affected by treatments, whereas PUN in the 12.5XSBM group was lower than in the other groups (P<0.05. In conclusion, the present results showed that partial replacement of SBM by XSBM may improve efficiency of dietary protein utilisation in pre-weaned calves, which warrants further studies.

    This study was conducted to evaluate the efficacy of a novel Buttiauxella phytase to pigs fed P-deficient, corn-soybean meal diets. One hundred and twenty crossbred piglets (9.53 ± 0.84 kg) were allocated to one of five treatments which consisted of four low P diets (0.61 % Ca and 0.46 % total P) supplemented with 0, 500, 1,000, or 20,000 FTU/kg phytase as well as a positive control diet (0.77 % Ca and 0.62 % total P). Each treatment had six replicated pens with four pigs per pen. Pigs were fed the experimental diets for 28 days. Phytase supplementation linearly improved (P phytase (20,000 FTU/kg) further increased (P phytase inclusion group, as well as ATTD of Ca and P. Metacarpal bone characteristics and several trace mineral concentration in bone, plasma, or organ tissues were linearly (P phytase. Super high dosing with phytase (20,000 FTU/kg) supplementation improved (P phytase supplementation (500 or 1,000 FTU/kg). In conclusion, supplementation of 500 FTU of Buttiauxella phytase/kg and above effectively hydrolyzed phytate in a low-P corn-soybean diet for pigs. In addition, a super high dosing with phytase (20,000 FTU/kg) improved macro- or micro mineral availability and growth performance.

    The ATLAS experiment is designed to study the proton-proton collisions produced at the Large Hadron Collider (LHC) at CERN. Its calorimeter system measures the energy and direction of final state particles with pseudo rapidity $|eta| < 4.9$. Accurate identification and measurement of the characteristics of electromagnetic objects (electrons/photons) are performed by liquid argon (LAr)-lead sampling calorimeters in the region $|eta| < 3.2$, using an innovative accordion geometry that provides a fast, uniform azimuthal response without gaps. The hadronic calorimeters measure the properties of hadrons, jets, and tau leptons, and also contribute to the measurement of the missing transverse energy and identification of muons. This is done in the region $|eta| < 1.7$ with a scintillator-steel sampling calorimeter, and in the region $1.4 < |eta| < 3.2$ with a copper-LAr sampling calorimeter. The coverage is extended to $|eta| < 4.9$ by an integrated forward calorimeter (FCal) based on LAr with copp...

L-SFP, M-SFP and VE birds showed higher body weight gain (BWG than Z-SFP and H-SFP birds during the starter period (P<0.05. No significant differences were observed among the treatments for feed intake (FI during the starter, grower and whole the experimental periods (P>0.05. Feed conversion ratio (FCR of M-SFP and VE birds were lower than that of H-SFP birds during the starter period (P<0.05. Moreover, no significant differences were observed for FCR or BWG between the treatments during the grower and whole the experimental periods (P>0.05. The blood total antioxidant capacity (TAC, malondialdehyde (MDA content and the activity of superoxide dismutase (SOD and glutathione peroxidase (GPX enzymes were not affected by dietary treatments at week 6 of age (P>0.05. It was concluded that although dietary SFP consumption can improve the performance of broiler chickens during the starter period under heat stress, it does not affect the performance during grower period or the blood antioxidant indices at week 6 of age.

    devised. It has been considered that the degradations of core performances resulting from increase of the transmutation rate are very important problems. From the analysis results of the state-of-art of the nuclear transmutation technology, the following technical research topics are determined as the technical solution ways for the future development and enhancement of the transmutation technology; 1) the improvement of core safety through the reduction of the coolant void reactivity worth by using the void duct assembly, 2) the design of a reference transmutation reactor for the future transmutation research through the change of the KALIMER-600 reactor core into the transmutation reactor and its core performance analysis, 3) the optimization study of the hybrid loading of uranium-free fuel and uranium fuel to improve the transmutation rate and the core safety parameters. Finally, the feasibility of the transmutation core suggested above where the void duct assemblies are devised to improve the sodium void reactivity worth and to achieve the power flattening under a single fuel enrichment and a single type of fuel assembly is analyzed and assessed. The results show that this core has its sodium coolant void reactivity less than 3$ and this core can transmutate the TRU nuclides discharged from two LWRs of the same thermal power.

    This study investigated the effects of a sport nutrition education intervention (SNEI) on dietary intake, knowledge, body composition, and performance in NCAA Division I baseball players. Resistance trained NCAA Division I baseball players (82.4 ± 8.2 kg; 1.83 ± 0.06 m; 13.7 ± 5 % body fat) participated in the study during 12 weeks of off-season training. Fifteen players volunteered for SNEI while 15 players matched for position served as controls (C) for body composition and performance. The nutrition intervention group (NI) received a 90 min SNEI encompassing energy intake (Kcal), carbohydrate (CHO), protein (PRO), fat, food sources, and hydration. Sport nutrition knowledge questionnaires were administered to NI pre and post. Nutritional status was determined by three-day dietary logs administered to NI pre and post. Body composition and performance (5-10-5 shuttle test, vertical jump, broad jump, 1 RM squat) were measured pre and post for C and NI. Knowledge increased in NI. Pro and fat, but not CHO intake increased in NI. FM decreased pre to post in NI (11.5 ± 4.8 vs. 10.5 ± 5.4 kg) but not C (11.3 ± 4.7 vs. 11.9 ± 4.5 kg). FFM increased pre to post with no differences between groups. The 5-10-5 shuttle times decreased significantly more in NI (4.58 ± 0.15 vs. 4.43 ± 0.13 sec) compared to C (4.56 ± 0.18 vs. 4.50 ± 0.16 sec). Jump and squat performance increased pre to post with no differences between groups. Our findings indicate that an off season SNEI is effective at improving sport nutrition knowledge and some, but not all, nutrient intakes and performance measures in Division I baseball players.

    Effects of low-density broiler breeder diets on offspring performance and mortality were studied using 2,100 female and 210 male Cobb 500 breeders. Breeder treatments involved 4 experimental groups and a control group with normal density diets (ND, 2,600 kcal of AME/kg during rearing and 2,800 kcal of AME/kg during laying). In treatment 2, nutrient densities were decreased by 12% (LD12) and 11% (LD11) during the rearing and laying periods, respectively, whereas in treatment 3, nutrient densities were decreased by 23% (LD23) and 21% (LD21) during the rearing and laying periods, respectively. The nutrient density in these treatments was decreased through inclusion of palm kernel meal, wheat bran, wheat gluten feed, and sunflower seed meal in the diets. Treatment 4 included diets with the same nutrient densities as in treatment 2 but included oats and sugar beet pulp (LD12(OP) and LD11(OP)). In treatment 5, the same low-density diet was given to the breeders as in treatment 2 during the rearing period, but it was followed by a normal density diet during the laying period (LD12-ND). Treatments were applied from 4 to 60 wk of age. On low-density diets, offspring showed an increased 1-d-old weight. As compared with offspring of breeders that received ND, the d 38 live weight of chickens from 29-wk-old breeders fed LD11 was improved. Mortality was reduced in offspring from 60-wk-old parent stock given low-density diets. The IgM titers in 35-d-old offspring from eggs with a lower-than-average weight were reduced when 29-wk-old broiler breeders were fed low-density diets. In offspring from eggs with a higher-than-average weight from 60-wk-old parent stock given LD11 or LD21 diets, IgM titers were higher compared with ND. It was concluded that low-density broiler breeder diets can improve offspring growth rates, reduce mortality, and reduce or increase immune responses, depending on breeder age and egg weight.

    Multiple micronutrient deficiencies exist in school going children in India and bridging the gap between nutrient intake and requirements is an effective way to combat the deficiencies. This study aimed to test the effect of a multi-micronutrient fortified malt and cocoa based milk beverage on the micronutrient status, cognition, physical performance and nutritional deficiencies of 7-10 years old south Indian children. A randomized, double blind placebo controlled study design was used with normal healthy children from low to middle income families, aged 7-10 years randomly assigned to receive either a multi-micronutrient fortified or an unfortified milk based control drink. The drinks were provided 6 days/week for 5 months. Assessments included anthropometry, blood biochemistry, physical performance and cognition at baseline and endline. The baseline characteristics of the study groups were similar. The changes in body weight and height were similar between the groups at the end of the study. Levels of vitamin B12, red cell folate and vitamin B2 significantly improved in the intervention group, while vitamin D, selenium and body iron showed no difference. The Hemoglobin (Hb) and serum ferritin levels of the control group decreased at endline, while those in the intervention group maintained their levels. The serum transferrin receptor levels increased in both the groups. The prevalence of iron deficiency and Vitamin B2 deficiency were significantly lower in the intervention group at endline. Overall improvement in cognitive and physical performance was seen in both the groups at endline, with no significant differences between the groups. The micronutrient fortified milk based drink was efficacious in improving the micronutrient status of Vitamin B2, Vitamin B12 and red cell folate and in preventing a decline in Hb level compared to an unfortified milk based drink. It also reduced anemia and the risk of deficiencies of iron, and B12, in apparently healthy children

    This experiment evaluated the effects of including peroxidized corn dried distillers grains with solubles (DDGS) in diets for sows and nursery pigs on growth performance, vitamin E (VE), and Se status, and the incidence of mulberry heart disease (MHD) of nursery pigs. Sows (n = 12) were fed corn-soybean meal diets (C-SBM) or C-SBM diets with DDGS (40% and 20% in gestation and lactation, respectively) for 3 parities. In the third parity, 108 weaned pigs (BW = 6.6 ± 0.36 kg) were blocked by BW within litter, assigned to pens (2 pigs/pen; 5 and 4 pens per litter for groups 1 and 2, respectively), and pens were assigned 1 of 3 nursery diets: 1) corn-soybean meal (CON), 2) 30% peroxidized DDGS (Ox-D), and 3) 30% Ox-D with 5 × NRC (1998) level of VE (Ox-D+5VE) for 7 wk, in a 2 × 3 factorial arrangement of sow and nursery diets (n = 9 pens/treatment). The peroxidized DDGS source in nursery diets contained concentrations of thiobarbituric acid reactive substances (TBARS) and peroxide values that were 25 and 27 times greater than a reference corn sample. Sow colostrum, milk, and serum, as well as pig serum and liver samples, were analyzed for α-tocopherol and Se concentrations. Pig serum was analyzed for glutathione peroxidase activity (GPx), TBARS, and sulfur-containing AA (SAA). Pig hearts were evaluated for gross and histopathological lesions indicative of MHD, but none were detected. Pigs from sows fed DDGS tended to have reduced (P = 0.07) VE in serum during lactation and reduced VE at weaning (P pigs from sows fed C-SBM. Inclusion of DDGS in sow diets reduced the VE status of pigs during lactation, but not in the nursery when MHD can be a concern. Pigs fed Ox-D+5VE (P = 0.08) tended to have, and those fed Ox-D (P = 0.04) had greater ADFI than pigs fed CON, but ADG was not affected (P > 0.1) by nursery diet. Feeding Ox-D or Ox-D+5VE increased (P pigs fed Ox-D or Ox-D+5VE compared with those fed C-SBM, which was likely due to greater (P pigs fed Ox-D. The

    Associations between Giardia lamblia infection and low serum concentrations of zinc have been reported in young children. Interestingly, relatively few studies have examined the effects of different dietary zinc levels on the parasite-infected host. The aims of this study were to compare the growth performance and zinc status in response to varying levels of dietary zinc and to measure the antibody-mediated response of mice during G. lamblia infection. Male CD-1 mice were fed using 1 of 4 experimental diets: adequate-zinc (ZnA), low-zinc (ZnL), high-zinc (ZnH) and supplemented-zinc (ZnS) diet containing 30, 10, 223 and 1383 mg Zn/kg respectively. After a 10 days feeding period, mice were inoculated orally with 5 × 106 G. lamblia trophozoites and were maintained on the assigned diet during the course of infection (30 days). Giardia-free mice fed ZnL diets were able to attain normal growth and antibody-mediated response. Giardia-infected mice fed ZnL and ZnA diets presented a significant growth retardation compared to non-infected controls. Zinc supplementation avoided this weight loss during G. lamblia infection and up-regulated the host’s humoral immune response by improving the production of specific antibodies. Clinical outcomes of zinc supplementation during giardiasis included significant weight gain, higher anti-G. lamblia IgG antibodies and improved serum zinc levels despite the ongoing infection. A maximum growth rate and antibody-mediated response were attained in mice fed ZnH diet. No further increases in body weight, zinc status and humoral immune capacity were noted by feeding higher zinc levels (ZnS) than the ZnH diet. These findings probably reflect biological effect of zinc that could be of public health importance in endemic areas of infection. PMID:24002196

    Although delayed union or pseudoarthrosis after lumbar arthrodesis has been recognized as a major radiographic complication, little has been known about the effect of fusion status on the patient's quality-of-life (QOL) outcome. The purpose of this study was to investigate the effects of fusion status after posterior lumbar interbody fusion (PLIF) on QOL outcomes by using the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ). Among 100 patients who underwent single level PLIF for spinal canal stenosis, 29 who had not achieved fusion (incomplete fusion group) and 29 age- and sex ratio-matched patients who had achieved fusion (fusion group) 6 months after surgery were enrolled. Overall clinical evaluation was performed before and 6 months after surgery: the physician determined the Japanese Orthopaedic Association Score for Low Back Pain (JOA score); the JOABPEQ and visual analogue scale (VAS) values were collected. The recovery rate of the JOA score, changes in all JOABPEQ subdomain scores and in the VAS values were calculated. All variables were compared between the groups. The preoperative JOA scores, JOABPEQ scores of all subdomains, and VAS values of all categories did not differ between the groups. The recovery rate was higher in the fusion group than the incomplete fusion group (p = 0.0185). The changes in the JOABPEQ scores for walking ability and social life function were significantly greater in the fusion group than the incomplete fusion group (walking ability, p = 0.0172; social life function, p = 0.0191). The postoperative VAS values and changes in the VAS values for all categories did not differ between the groups. Incomplete fusion after PLIF correlated with poor improvement in walking ability and social life function. Therefore, the achievement of fusion after PLIF is essential to obtain better patient QOL outcomes.

    Full Text Available Background: Type 2 diabetes mellitus, as a noncommunicable disease, is the main public health challenge in the 21st century. The prevalence of di¬abetes mellitus adjusted for the world population in Iran was 8% until the year 2010. Lipid levels are considered as important parameters to be eva¬luated, as high serum lipid levels are often reported as a complication in patients with diabetes mellitus. It is claimed that functional foods may im¬prove complications of diabetes mellitus, so this study was designed to evaluate the effects of high performance inulin on glycemic status and lipid profile of women with type 2 diabetes.Methods: The study was a randomized controlled clinical trial. Forty-nine type 2 diabetic females (fiber intake <30g/d, 25status and lipid profile indices were measured pre and post intervention. Data were analyzed using SPSS software (verision11.5. Paired, unpaired t-test and ANCOVA were used to compare quantitative variables.Results: Supplementation with inulin caused a significant reduction in FBS (8.50%, HbA1c (10.40%, total cholesterol (12.90%, triglyceride (23.60 %, LDL-c (35.30 %, LDL-c/HDL-c ratio (16.25% and TC/HDL-c ratio (25.20% and increased HDL-c (19.90%. The changes for the control group parameters were not significant at the end of study. Conclusion: Inulin may help to control diabetes and its complications via improving glycemic and lipid parameters.

Two groups were fed diets with (OEO; n=28 or without (Control; n=26 supplemental 15 mg/kg OEO during gestation and lactation. The serum levels of reactive oxygen species (ROS (P<0.05, 8-hydroxy-deoxyguanosine (8-OHdG (P<0.05, and thiobarbituric acid reactive substances (TBARS (P<0.05 were higher during gestation (days 90 and 109 and lactation (days 1 and 3 than in early gestation (day 10. Compared with the control group, the OEO diet significantly reduced sows’ serum concentrations of 8-OHdG (P<0.05 and TBARS (P<0.01 on day 1 of lactation. The OEO diet increased the sows’ counts of faecal lactobacillus (P<0.001 while reducing Escherichia coli (P<0.001 and Enterococcus (P<0.001. In the third week of lactation the treatment tended to increase sow’s feed intake (P=0.07, which resulted in higher average daily gain (P<0.01 of piglets. Our results demonstrated that there is an increased systemic oxidative stress during late gestation and early lactation of sows. The OEO supplementation to sows’ diet improved performance of their piglets, which may be attributed to the reduced oxidative stress.

    Lower cognitive performance is associated with poorer health and functioning throughout the lifespan and disproportionately affects children from lower socioeconomic status (SES) populations. Previous studies reporting positive associations between child home enrichment and cognitive performance generally had a limited distribution of SES. We evaluated the associations of SES and child enrichment with cognitive performance in a population with a wide range of SES, particularly whether enrichment attenuates associations with SES. Children were sampled from a case–control study of small-for-gestational-age (SGA) conducted in a public hospital serving a low SES population (final n = 198) and a private hospital serving a middle-to-high SES population (final n = 253). SES (maternal education and income) and perinatal factors (SGA, maternal smoking and drinking) were obtained from maternal birth interview. Five child home enrichment factors (e.g. books in home) and preschool attendance were obtained from follow-up interview at age 4.5 years. Cognitive performance was assessed with the Differential Ability Scales (DAS), a standardized psychometric test administered at follow-up. SES and enrichment scores were created by combining individual factors. Analyses were adjusted for perinatal factors. Children from the public birth hospital had a significantly lower mean DAS general cognitive ability (GCA) score than children born at the private birth hospital (adjusted mean difference −21.4, 95% CI: −24.0, −18.7); this was substantially attenuated by adjustment for individual SES, child enrichment factors, and preschool attendance (adjusted mean difference −5.1, 95% CI: −9.5, −0.7). Individual-level SES score was associated with DAS score, beyond the general SES effect associated with hospital of birth. Adjustment for preschool attendance and home enrichment score attenuated the association between individual SES score and adjusted mean DAS-GCA among children born

    The present study aimed to investigate the effects of different iron (Fe) supply to sows during gestation on their reproductive performance and placental Fe load. Additionally, the Fe status of the corresponding offspring was assessed. Twenty multiparous sows were fed from insemination to farrowing with isoenergetic and isonitrogenic balanced diets differing in Fe content. The diet low in Fe (Group -Fe) was mainly composed of soybean meal and maize meal and had a Fe content of 114 mg/kg DM. For the diet high in Fe (Group +Fe), the diet was supplemented with Fe(II)SO4 · 7H2O to a total Fe content of 256 mg/kg. Blood characteristics (haemoglobin, haematocrit, mean corpuscular haem concentration, total Fe-binding capacity, transferrin saturation) of all sows were measured at the beginning and at the end of gestation. Daily Fe retention was calculated at the day of farrowing. After birth, reproductive performance (litter size, piglet weight, litter weight), placental Fe content and Fe blood characteristics of the piglets were determined. Apparent daily Fe retention tended to be greater in Group +Fe (p sows did not show any variations between feeding groups, neither at the beginning nor at the end of pregnancy, whereas placental Fe content was lower in Group -Fe (p sows were supplied according to the current Fe recommendations, a significant decline in reproductive performance of Group -Fe was recognised. Therefore, it was concluded that the re-evaluation of the gross Fe requirements of pregnant sows is inevitable to accommodate the current feeding recommendations.

    The present study was conducted to investigate the influence of dietary supplementation with different levels of fermented Ginkgo biloba leaves (FGBL) on growth performance, slaughter performance, meat quality, antioxidant enzyme capacity, and free radical scavenging activities of muscles in broiler chickens. A total of 648 one-d-old broiler chickens were randomly allocated into six dietary treatments, including control group (CON group: basal diet), FGBL1, FGBL2, FGBL3, FGBL4, and FGBL5 groups (basal diet containing 1.5, 2.5, 3.5, 4.5, and 5.5 g/kg FGBL, respectively). Body weight gain and feed intake were recorded at 1, 21, and 42 d. At 42 d, 2 birds from each replicate were slaughtered. The results indicated that 3.5 g/kg FGBL diet significantly increased (P muscle, cooking loss in thigh muscle and lower 24 h and 48 h drip loss in both breast and thigh muscles than those of other groups. Furthermore, birds in the FGBL3 and FGBL4 groups increased (P muscles, and the scavenging activities of 2,2΄-azino-bis (3-ethylbenzothiazoline-6-sulfonic) acid radical, OH•, and O2•- in thigh muscle, decreased (P muscle, as compared to the CON group. In conclusion, FGBL had the potential to improve the growth performance, meat quality and antioxidant status of broiler chickens.

    Unexpected fatal events in patients with head and neck cancers undergoing concurrent chemoradiation therapy are a clinical concern. Malnutrition, which is reported frequently in head and neck cancer patients, are associated with immunity derangement. The purpose of this study was to identify risk factors for early death of patients undergoing chemoradiation. We retrospectively analyzed the records of 194 stage III, IVA, and IVB head and neck cancer patients who were treated with chemoradiation between 2007 and 2009. We defined early death as death while receiving chemoradiation or within 60 days of treatment completion. Risk factors for early death were tested using univariate and multivariate analyses. Fourteen patients (7.2 %) experienced early death, 78.6 % of whom died of infection. Univariate analysis revealed significant correlations between early death and several pretreatment variables, including Eastern Cooperative Oncology Group performance status (PS) >1, hemoglobin total lymphocyte count 1, BMI total lymphocyte count malnutrition before chemoradiation independently predict early death in locally advanced head and neck cancer patients undergoing chemoradiation. Cautious management of head and neck cancer patients with these risk factors is required throughout chemoradiation period.

    Enrichment of eggs with folate is possible when dietary folic acid levels are increased. However, development of optimal strategies for the production of folate-enriched eggs requires knowledge as to differences due to strain of bird and a greater understanding of the factors limiting egg folate deposition. To this end, a study was designed to determine the response of two leghorn strains that differ in production performance. Hyline W36 and W98 hens (n = 6 per diet) received a barley-based ration containing 0, 2, 4, 8, 16, 32, 64, or 128 mg/kg of crystalline folic acid for 21 d. Response criteria included production parameters, measures of blood folate status, and egg folate content. Significant (P folic acid through a reduction in plasma homocysteine concentrations, suggesting that this strain has a higher requirement for folate than the W36 strain. Overall, egg folate content is maximized when crystalline folic acid is supplemented to the diet at 2 mg/kg or higher. Higher levels of egg folate are not achieved due to the saturation of the precursor pool for egg folate deposition.

    This study was conducted to determine the effect of tea polyphenols (TP) on production performance, egg quality, and hepatic-antioxidant status of laying hens in vanadium-containing diets. A total of 300 Lohman laying hens (67 wk old) were used in a 1 plus 3 × 3 experiment design in which hens were given either a diet without vanadium and TP supplementation (control) or diets supplemented with 5, 10, or 15 mg V/kg and TP (0, 600, 1,000 mg/kg) diets for 8 wk, which included 2 phases: a 5-wk accumulation phase and a 3-wk depletion phase. During the accumulation phase, dietary vanadium addition decreased (linear, P hens fed 15 mg/kg vanadium and 600 mg/kg TP showed no difference from the control diet only after 1 wk withdrawal. In the liver, the activity of glutathione S-transferases and glutathione peroxidase was increased (linear, P hens from the adverse effect of vanadium on egg quality, liver antioxidant stress and shorten the recovery time.

    Conjugated linoleic acid (CLA) reduces mammary milk fat synthesis in a dose-dependent manner. Our objective was to determine the effects of lipid-encapsulated CLA (LE-CLA) supplementation on milk production, reproductive performance and metabolic responses in lactating dairy cows fed a grass silage-based diet. Seventy-two Holstein-Friesian cows (32 primiparous and 40 multiparous) were used in a completely randomized block design. Cows received either 80 g of LE-CLA daily or 60 g of calcium salts of palm fatty acids daily (control) from parturition until 60 days in milk. LE-CLA contained a 50:50 mix of cis-9,trans-11 CLA and trans-10,cis-12 CLA, resulting in a daily intake of 6 g of each isomer. Milk production and dry matter intake were recorded daily, and blood samples were collected 3-times a week. Blood samples were analysed for circulating concentrations of glucose, non-esterified fatty acids (NEFA), β-hydroxybutyrate (BHBA), insulin and insulin-like growth factor-I (IGF-I). Progesterone was measured in blood samples collected after the first post-partum insemination. Ovarian ultrasound examinations commenced at 8-10 d post partum and were carried out 3-times a week until first ovulation. LE-CLA treatment resulted in decreased milk fat concentration, with consequent improvements in energy balance and body condition score (BCS). The peak concentration of NEFA in blood was reduced by LE-CLA, but circulating concentrations of insulin, glucose, IGF-I, BHBA and progesterone were not affected. There was no effect of LE-CLA supplementation on the post-partum interval to first ovulation. Services per conception tended to be reduced. The reduction in milk energy output and improvement in energy status and BCS in LE-CLA-supplemented cows provides a strong rationale for further studies with greater cow numbers to test effects on reproductive performance.

    The present study investigated the effects of dietary supplementation of a seaweed extract (SWE) to sows and weaned pigs on post-weaning growth performance, intestinal morphology, intestinal microflora, volatile fatty acid concentrations and immune status of pigs at days 11 and 117 post-weaning. Gestating sows (n 20) were supplemented with a SWE (0 v. 10·0 g/d) from day 107 of gestation until weaning (day 26). At weaning, pigs (four pigs per sow) were divided into two groups based on sow diet during lactation and supplemented with a SWE (0 v. 2·8 g/kg diet), resulting in four treatment groups: (1) BB (basal sows-basal pigs); (2) BS (basal sows-treated pigs); (3) SB (treated sows-basal pigs); (4) SS (treated sows-treated pigs). Pigs weaned from SWE-supplemented sows had a higher average daily gain (ADG) between days 0 and 21 (P pigs weaned from non-SWE-supplemented sows. Pigs offered post-weaning diets (PW) containing SWE had decreased colonic Escherichia coli populations on day 11 (P Pigs offered PW containing SWE had a greater mRNA abundance of MUC2 in the colon at day 11 post-weaning (P pigs offered unsupplemented diets. In conclusion, these results demonstrate that SWE supplementation post-weaning provides a dietary means to improve gut health and to enhance growth performance in starter pigs. Dietary SWE supplementation increased ADG during the grower-finisher (GF) phases. However, there was no growth response to SWE inclusion in GF diets when pigs were weaned from SWE-supplemented sows.

    1. This study was carried out to evaluate the impact of ginger (Zingiber officinale) feed supplementation on growth performance, antioxidant status, carcass characteristics and blood parameters in broiler chicks under conditions of heat stress (32 ± 2ºC for 8 h per d). 2. A total of 336 d-old male broiler chicks (Cobb-500) were randomly assigned to one of 6 dietary groups representing: basal diet with no supplement as control, basal diet containing 100 mg/kg vitamin E as positive control, basal diets containing either 7.5 or 15 g/kg of ginger root powder, and diets containing 75 or 150 mg/kg of ginger essential oil. 3. The results indicated that at 22 d of age, the group receiving 7.5 g/kg of ginger root powder experienced significantly increased body weight (BW) and body weight gain (BWG) compared to the control group. There were no significant difference among the diet groups regarding BW, BWG, feed intake (FI) or feed conversion ratio (FCR) at 42 and 49 d of age. 4. The inclusion of powder and essential oil of ginger in broiler diets did not affect carcass characteristics and blood parameters of the chickens. However, in the group receiving 150 mg/kg ginger essential oil, the total superoxide dismutase (TSOD) activity in liver increased compared to the control group. Malondialdehyde (MDA) concentrations in liver also decreased in the groups receiving ginger powder and essential oil compared to that in the control group. There were no significant difference between experimental groups regarding glutathione peroxidise (Gpx), TSOD and catalase (CAT) enzymes in red blood cells. All dietary groups increased total antioxidant capacity (TAC) and decreased MDA concentration in serum compared to the control group. 5. The results of this study suggest that ginger powder and essential oils may be a suitable replacement for synthetic antioxidants in broiler diets. Results also suggest that ginger powder might be better than extracted essential oil for improving

    The effect of dietary inclusion of soy protein concentrate (SPC) and simultaneous supplementation with taurine on the growth, hematology, blood biochemistry, and liver histology of totoaba (Totoaba macdonaldi) juveniles was assessed. Four isoproteic and isolipidic diets were formulated containing either 30 or 60% of SPC (diets S30 and S60), supplemented or not with 1% of taurine (diets S30T and S60T). A fishmeal-based diet formulated for totoaba nutritional requirements, without SPC and taurine supplementation, was used as a reference diet. Triplicate groups of 32 totoaba juveniles (average body weight 7.5 ± 0.6 g) were fed these diets for 45 days. Results showed that growth performance in fish fed S30, S30T, and S60T was similar to fish fed the reference diet. Red blood cells and hematocrit in fish fed with supplemented taurine in both levels of SPC (S30T and S60T) were similar to the fish fed the RD; the addition of taurine improved the state of hydration of totoaba. Plasmatic hemoglobin in fish fed the lower SPC level was similar to fish fed the RD. The mean corpuscular hemoglobin concentration in fish fed S30T was similar to fish fed the RD, taurine supplementation prevented the development of hypochromic anemia in this group of fish. Plasmatic albumin in fish fed S30 was similar to fish fed the RD. Plasmatic total protein and globulin concentration increased and AL:GLB (albumin:globulin ratio) decreased in fish fed the SPC-based diets despite taurine supplementation. The protein profile showed that taurine supplementation did not prevent a possible inflammatory process (increased globulins, decreased AL:GLB) in juvenile totoaba fed both levels of SPC. Glucose concentration was similar in fish fed S30, S30T, and S60T. The histological hepatic index was highest in fish fed S60. These results suggest that with an appropriate nutritional level, taurine may play an important modulatory role in the hematology and blood biochemistry status in totoaba fed SPC

    A total of 180 crossbred pigs (Duroc × Landrace × Large White; BW = 47.1 ± 4.8 kg) were used to investigate the effects of totally replacing inorganic trace minerals (ITMs) by organically bound trace minerals (OTMs) on growth performance, tissue mineral status, liver antioxidant enzyme activities, and fecal mineral excretion in grower-finisher pigs. A randomized complete block design with three treatments and six replicates (n = 10 pigs per pen) was used in this 69-day, 2-phase feeding trial. Experimental treatments were as follows: (1) a basal diet without trace mineral supplementation, (2) basal + ITMs (Fe, Mn, and Zn from sulfates, Cu oxychloride, and sodium selenite providing commercially recommended levels in China at 125, 22.5, 117.5, 30, and 0.3 mg/kg, respectively), and 3) basal + OTMs (Fe, Mn, Zn, and Cu from Bioplex and Se as Sel-Plex (Alltech Inc., Nicholasville, KY) providing levels identical to ITMs). No significant differences (P > 0.05) were observed in ADG, ADFI, or G:F among the treatments during the entire grower-finisher period. Supplementation with minerals, regardless of source, increased (P supplemented. Pigs supplemented with OTMs displayed greater activities of Cu/Zn-SOD, ALP, and GSH-Px in the liver compared to pigs supplemented with ITMs. Dietary mineral supplementation to pig diets greatly increased (P mineral (Fe, Mn, Zn, Cu, and Se) excretion in both grower and finisher phases. Fecal concentrations of Zn, Cu, and Se excretion were lower (P supplementation than that in pigs fed diets containing ITMs. These results indicate that use of organic trace minerals, as well as no trace mineral supplementation, did not influence pig growth performance. Totally replacing ITMs by equivalent levels of OTMs could improve hepatic Cu/Zn-SOD, ALP, and GSH-Px activities and reduce fecal Mn, Cu, and Se excretion for grower-finisher pigs when supplemented at commercially recommended levels.

    A 4×2 factorial experiment with four supplemental levels of copper (0, 20, 40, or 60 mg copper per kg dry matter) from copper sulfate and two supplemental levels of zinc (40 or 200 mg zinc per kg dry matter) from zinc sulfate was conducted to investigate the effects of dietary copper and zinc supplementation on growth performance, tissue mineral retention, antioxidant status, and fur quality in growing-furring blue foxes. One hundred and twenty healthy 15-week-old male blue foxes were randomly allocated to eight dietary treatments with 15 replicates per treatment for a 70-day trial from mid-September to pelting in December. The average daily gain and feed conversion ratio were increased with copper supplementation in the first 35 days as well as the overall period (Pzinc did not affect body gain (P>0.10) and feed intake (P>0.10) but improved feed conversion (Pzinc throughout the experiment. No copper×zinc interaction was observed for growth performance except that a tendency (P=0.09) was found for feed intake in the first 35 days. Supplementation of copper or zinc improved crude fat digestibility (Pzinc addition (Pzinc was affected only by dietary zinc addition (P0.05). However, the level of copper in the liver was increased with copper supplementation (Pzinc supplementation (P=0.08). Dietary zinc addition tended to increase the activity of alkaline phosphatase (P=0.07). The activities of copper-zinc superoxide dismutase and catalase tended to increase by copper (P=0.08) and zinc addition (P=0.05). Moreover, a copper×zinc interaction was observed for catalase in the experiment (Pzinc levels (Pzinc supplementation can improve growth by increasing feed intake and improving fat digestibility. Additionally, copper and zinc can enhance the antioxidant capacity of blue foxes. This study also indicates that additional zinc up to 200 mg/kg did not exert significant adverse effects on the copper metabolism of growing-furring blue foxes.

A dynamic warm-up protocol containing seven specific resistance movements with specific resistance corresponding to different percentages of body weight (2%, 4%, 6%, 8%, 10% was applied randomly on non consecutive days. Effects of different warm-up protocols were assessed by pre-/post- exercise changes in jump height in the countermovement jump (CMJ and the squat jump (SJ measured using a force platform and changes in hip and knee joint angles at the end of the eccentric phase measured using a video camera. A significant increase in jump height was observed in the dynamic resistance warm-up conducted with different percentages of body weight (p 0.05. In jump movements before and after the warm-up, while no significant difference between the vertical ground reaction forces applied by athletes was observed (p>0.05, in some cases of resistance, a significant reduction was observed in hip and knee joint angles (p<0.05. The dynamic resistance warm-up method was found to cause changes in the kinematics of jumping movements, as well as an increase in jump height values. As a result, dynamic warm-up exercises could be applicable in cases of resistance corresponding to 6-10% of body weight applied in horizontal and vertical directions in order to increase the jump performance acutely.

    Full Text Available Introduction Broiler chickens are intensively selected for productive traits. The management of these highly productive animals must be optimal to allow their full genetic potential to be expressed. If this is not done, inefficient production and several metabolic diseases such as ascites become apparent. Investigations in mammals indicated that the b- adrenoreceptor characteristics are differentially regulated by chronic hypoxia and play an important role in the cardiovascular system. The density of b-adrenergic receptors was higher in cardiac cells of ascites sensitive birds compared with ascites-resistant ones. Moreover, the characteristics of b-adreno receptors are different in cardiac cells of birds with right ventricular hypertrophy and heart failure compared with healthy birds. Treatment with the selective b1-adrenoceptor blocker, atenolol, abolished right ventricular hypertrophy in response to hypoxia compared with normoxic condition in rats. Materials and Methods This study investigated the comparative effects of different levels of atenolol Growth performance, Mortality due to ascites, antioxidant status and blood parameters in broilers under induced ascites. Six hundred one-day-old male broilers (Ross 308 in a completely randomized experimental design with four treatments (Positive control, negative control, and two levels of 30 and 60 ppm atenolol with five replicates of thirty birds were applied. Birds in positive control were reared in natural temperature without atenolol, the other bird groups were reared in cold temperature with 0, 30 and 60 ppm atenolol. The average daily feed intake (ADFI, average daily weight gain (ADWG and feed conversion ratio (FCR for each group of birds were calculated and mortality was daily weighed, recorded and used to correct the FCR. Observations were made daily to record the incidence of ascites and mortality. Diagnosis of ascites generally depends on observation of the following symptoms: (1 right

    Heat stress (HS), one of the most serious climate problems of tropical and subtropical countries, negatively affects the production performance of broilers. Keeping this in view, the current study was aimed at elucidating the effects of supplementing betaine (Bet) and dried turmeric rhizome powder (TRP), either singly or in combination, on growth performance, leukocyte profile, humoral immunity, and antioxidant status in broilers kept under chronic HS. A total of 625 one-day-old Ross male chicks were randomly assigned to five treatment groups (5 replicates of 25 birds per replicate pen). From day 1, the birds were either kept at the thermoneutral zone (TN) or exposed to HS (33 ± 1°C) to the conclusion of study, day 42.

    Full Text Available In Senegalese sole (Solea senegalensis aquaculture, infectious diseases represent a major challenge, leading to significant economic losses (Arijo et al, 2005. According to FAO / WHO (2001, probiotics are defined as "live micro-organisms which, when administered in adequate amounts, confer a health benefit on the host". Previous studies working with different fish species provided evidence on the effectiveness of various probiotic bacteria in promoting the fish welfare (Castex et al., 2009; Hernandez et al., 2010; Merrifield et al., 2011. In the current study, we evaluated the effects of dietary probiotic supplementation intercropped with plant protein as fishmeal replacement on the growth performance and immunological status in sole (Solea senegalensis. Fish were fed for 10 weeks on six isonitrogenous and isolipidic diets (55% protein and 8% lipid, dry matter basis, formulated to have 35% or 72% of fishmeal replacement by plant protein (PP35 or PP72 intercropped with three probiotic supplementation (NO – unsupplemented, PRO1 and PRO2, in a 2 × 3 factorial design. The probiotics were tested at a dosage recommended by the manufacturer. PRO1 was a multi-species probiotic bacteria (Bacillus sp., Pediococcus sp., Enterococcus sp., Lactobacillus sp. supplemented at 1.8 × 1010 CFU kg-1 diet (CFU - colony forming unit and PRO2 was an autolyzed yeast (Saccharomyces cerevisiae supplemented at 4g kg-1 diet. Zootechnical parameters were measured at start and the end of the feeding trial for growth performance determination. Plasma was collected at 3, 17, 38 and 73 days of feeding dietary treatment for the determination of innate immune response (plasma lysozyme and peroxidase contents, plasma alternative complement pathway activity – ACH50 in order to detect differences between treatments as well to identify the influence of long or short-time probiotic supplementation. Fish with an initial body weight of 33.1 ± 0.2 g grew to a maximum final body

    Full Text Available Abstract Background An important aim of antenatal care is to improve maternal health- and well being of which oral health is an important part. This study aimed to estimate the prevalence of oral impacts on daily performances (OIDP during pregnancy, using a locally adapted OIDP inventory, and to document how periodontal status, tooth-loss and reported periodontal problems are related to oral impacts. Methods Pregnant women at about 7 months gestational age who were members of a community based multi-center cluster randomized community trial: PROMISE EBF: Safety and Efficacy of Exclusive Breast feeding in the Era of HIV in Sub-Saharan Africa, were recruited in the district of Mbale, Eastern Uganda between January 2006 and June 2008. A total of 877 women (participation rate 877/886, 98%, mean age 25.6, sd 6.4 completed an interview and 713 (participation rate 713/886, 80.6%, mean age 25.5 sd 6.6 were examined clinically with respect to tooth-loss and according to the Community Periodontal Index, CPI. Results Seven of the original 8 OIDP items were translated into the local language. Cronbach's alpha was 0.85 and 0.80 in urban and rural areas, respectively. The prevalence of oral impacts was 25% in the urban and 30% in the rural area. Corresponding estimates for CPI>0 were 63% and 68%. Adjusted ORs for having any oral impact were 1.1 (95% CI 0.7-1.7, 1.9 (95% CI 1.2-3.1, 1.7 (1.1-2.7 and 2.0 (0.9-4.4 if having respectively, CPI>0, at least one tooth lost, tooth loss in molars and tooth loss in molar-and anterior regions. The Adjusted ORs for any oral impact if reporting periodontal problems ranged from 2.7(95% CI 1.8-4.2 (bad breath through 8.6(95% CI 5.6-12.9 (chewing problem to 22.3 (95% CI 13.3-35.9 (toothache. Conclusion A substantial proportion of pregnant women experienced oral impacts. The OIDP impacts were most and least substantial regarding functional- and social concerns, respectively.

    The aim of this study was to evaluate the effects of a team-building learning project on job satisfaction, psychological wellbeing, and performance of health care workers involved in the process of organ and tissue donation. The project was conducted between June and September 2011 and consisted of two one-day meetings and a one week sailing, involving 20 staff members. GHQ-12, MBI-HSS, and 25 items taken from the Multidimensional Organizational Health Questionnaire (MOHQ) were used to assess health status, burnout, and job satisfaction. Results of the descriptive analyses were expressed as mean ± SD and as counts and percentages; Chi-square test was used to evaluate statistical significance of differences before and after the initiative. 6 (30,0%) participants showed the likelihood to suffering from anxiety and depression (i.e. recognized as 'cases' by the GHQ-12), 3 (15.0%) of them at baseline and 3 (15.0%), different from the previous ones, in the post-intervention. The presence of stress was revealed in 9 (45.0%) and 12 subjects (60.0%) before and after the experience, respectively (6 subjects showed the presence of stress in both circumstances). We documented 4 burnout cases, 3 (15.0%) at baseline and 1 (5.0%) after the experience. Nevertheless, about 80% of the participants showed a high degree ofjob satisfaction, in terms of positive influence of job in the professional satisfaction and of clear satisfaction for the organization, during both evaluation. In respect to 2010, the number of organ donors and that of ocular tissue donors improved of about 16% and 10%, respectively, during the year of the project and in the following year (mean value). We recognize that our team-building project for personnel involved in the stressful and demanding setting of organ and tissue donation, worthwhile and recompensing at the same time, possibly influenced the personal commitment and the quality of job provided. The high level of stress showed by participants should be

    We investigated the interactive effect of ammonia toxicity, salinity challenge and nutritional status on the ecophysiological performance of European sea bass (Dicentrarchus labrax). Fish were progressively acclimated to normal seawater (32ppt), to brackish water (20ppt and 10ppt) and to hyposaline water (2.5ppt). Following acclimation to different salinities for two weeks, fish were exposed to high environmental ammonia (HEA, 20mg/L ∼1.18mM representing 50% of 96h LC50 value for ammonia) for 12h, 48h, 84h and 180h, and were either fed (2% body weight) or fasted (unfed for 7 days prior to HEA exposure). Biochemical responses such as ammonia (Jamm) and urea excretion rate, plasma ammonia, urea and lactate, plasma ions (Na(+), Cl(-) and K(+)) and osmolality, muscle water content (MWC) and liver and muscle energy budget (glycogen, lipid and protein), as well as branchial Na(+)/K(+)-ATPase (NKA) and H(+)-ATPase activity, and branchial mRNA expression of NKA and Na(+)/K(+)/2Cl(-) co-transporter (NKCC1) were investigated in order to understand metabolic and ion- osmoregulatory consequences of the experimental conditions. During HEA, Jamm was inhibited in fasted fish at 10ppt, while fed fish were still able to excrete efficiently. At 2.5ppt, both feeding groups subjected to HEA experienced severe reductions and eventually a reversion in Jamm. Overall, the build-up of plasma ammonia in HEA exposed fed fish was much lower than fasted ones. Unlike fasted fish, fed fish acclimated to lower salinities (10ppt-2.5ppt) could maintain plasma osmolality, [Na(+)], [Cl(-)] and MWC during HEA exposure. Thus fed fish were able to sustain ion-osmotic homeostasis which was associated with a more pronounced up-regulation in NKA expression and activity. At 2.5ppt both feeding groups activated H(+)-ATPase. The expression of NKCC1 was down-regulated at lower salinities in both fed and fasted fish, but was upregulated within each salinity after a few days of HEA exposure. Though an

    The scope of this paper was to investigate the relationship between the nutritional status and the motor skills of the elderly registered in the Family Health Program in the urban area of Vitória de Santo Antão in the State of Pernambuco, by means of a transversal epistemological descriptive-analytical field study. The participants of this survey were 235 elders, both male and female of 60-years-old and over registered in the family health program in the urban area of the city. The nutritional status was evaluated by the body mass index and the circumference of the calf. Four motor tests were used to evaluate motor performance: Time Up&Go, Tinetti's Index, Functional Reach and Unipodal Support. The associations were checked using Spearman's correlation. The association of the nutritional status with the motor tests was statistically significant among males* or females**: (Time Up&Go rho = 0.290* / 350**; Functional Reach rho = 0.232* / 352**; Tinetti's Index rho = 243* / 363** and Unipodal Support rho = 221* / 475**. The evaluation of the results revealed an association between nutritional status and functional capacity of the elders no matter what gender; with obesity being a limiting nutritional condition to adequate performance in the tests.

    Full Text Available Introduction Iran has good condition in fruit production among all countries in the world. Lemon, grape and apple are fruits that are produced in large scale in our country. For economical use of these fruits, there are different factories which produce fruit juices. Pulps are the main waste that remain after juicing fruits. Pulps contain some nutrients such as vitamins and minerals and secondary substances, also in contrast to common diets ingredients, there are very cheap and using them in diets may reduce the production price. As pulps contain high level of fiber, can be easily used without any adverse effects in ruminant, but in poultry, especially in broilers using higher level of pulps may be not possible. However, using low level of pulps do not have any adverse effects on performance and blood parameters and can improve the meat quality and blood biochemical and immune parameters. Moreover discharge of these wastes to environment can cause serious environmental problems. This experiment was conducted to evaluate the effects of lemon, grape and apple pulps on performance, carcass traits, digestive tract characteristic, intestinal morphology and immune status of broilers. Materials and Methods In this experiment 240 Ross-308 broilers were used in 5 treatments, 4 replicates and 12 chicks in each replicate in a completely randomized design. Experimental groups included: 1 control group (without using pulp, 2 group with 150 mg/kg vitamin E (as positive control group, 3 group with 3% lemon pulp, 4 group with 3% grape pulp, 5 group with 3% apple pulp. Grower diets from 11 to 24 days and finisher diets from 25 to 42 days were used by broilers. In the experimental periods all chickens in experimental groups had free accsess to feed and water. The lighting program included: 23 h light and 1 h darkness in all the experimental period.Feed intake and weight gain were measured at the end of growing and finishing and whole periods.

    It remains controversial whether open or laparoscopic surgery should be indicated for elderly patients with colorectal cancer and a poor performance status. In those patients aged 80 years or older with Eastern Cooperative Oncology Group performance status score of 2 or greater who received elective surgery for stage 0 to stage III colorectal adenocarcinoma and had no concomitant malignancies and who were enrolled in a multicenter case-control study entitled "Retrospective study of laparoscopic colorectal surgery for elderly patients" that was conducted in Japan between 2003 and 2007, background characteristics and short-term and long-term outcomes for open surgery and laparoscopic surgery were compared. Of the 398 patients included, 295 underwent open surgery and 103 underwent laparoscopic surgery. There were no significant differences in the baseline characteristics between open surgery and laparoscopic surgery patients, except for previous abdominal surgery and TNM stage. The median operation duration was shorter with open surgery (open surgery, 153 min; laparoscopic surgery, 202 min; P cancer patients with a poor performance status is safe and not inferior to open surgery in terms of overall survival.

    To compare the diagnostic performance of whole-body magnetic resonance imaging (WBMRI) versus {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography/computed tomography (PET/CT) for determination of remission status in patients with multiple myeloma (MM) after stem cell transplantation (SCT). Thirty-one patients were examined by both WBMRI and PET/CT after SCT. Imaging results and clinical remission status as determined by the clinical gold standard (Uniform Response Criteria) were compared. One hundred four lesions were detected in 21 patients. PET/CT had a sensitivity of 50.0 %, a specificity of 85.7 %, a positive predictive value of 62.5 %, a negative predictive value of 78.3 %, and an overall accuracy of 74.2 % for determination of remission status. MRI had a sensitivity of 80.0 %, a specificity of 38.1 %, a positive predictive value of 38.1 %, a negative predictive value of 80 %, and an overall accuracy of 51.6 %. Concordant results were observed in only 12 (11.5 %) of the 104 lesions. In the post-treatment setting, both FDG PET/CT and WBMRI provide information about the extent of disease, allowing for a more comprehensive evaluation of persisting or recurrent myeloma. MRI may often be false positive because of persistent non-viable lesions. Therefore, PET/CT might be more suitable than MRI for determination of remission status. (orig.)

    The current experiment was conducted to evaluate the effects of feeding dried sweet orange peel (SOP) and lemon grass leaves (LGL) as feed additives on broiler growth performance, serum metabolites, and antioxidant status. A total of 192-day-old (Ross 308) broiler chickens were distributed randomly into 4 dietary treatments with 4 replicates per each treatment. The dietary treatments included a control diet without any feed additive (T1), a diet containing 0.8 % SOP (T2), a diet containing 0.8 % LGL (T3), and a diet containing combination of 0.4 % SOP + 0.4 % LGL (T4) was fed during the growth period from 22 to 42 days. Feed intake (FI), body weight gain (BWG), feed conversion ratio (FCR), carcass traits, serum components, and antioxidant status were measured. At the end of the experimental period, the results indicated that supplementation of SOP and LGL alone or in combination did not significantly (P > 0.05) affect BWG, FI, FCR, and carcass characteristics in broiler chickens. Serum total protein was increased significantly (P < 0.05) in T3 and T4 compared to the other treatments. Also, serum globulin increased significantly (P < 0.05) in the treated groups. Serum glucose, low density lipoprotein, triglyceride, and very low density lipoprotein decreased significantly (P < 0.05) in the treatment groups, while cholesterol and high-density lipoprotein decreased in T2 compared to the other groups. Significantly (P < 0.05) higher total antioxidant status was observed in T2 compared to the other treatments. In conclusion, these results indicate that SOP, LGL, and their combination may positively modify some serum components and the antioxidant status without any beneficial effect on growth performance and carcass traits in broiler chickens.

    The interaction of iron components with swelling clay materials in the EBS has received relatively little attention so far in safety assessment studies. It is however widely recognised that such interaction processes (e.g. corrosion, mineral alteration) need to be considered since they have the potential to impair repository long-term safety. A workshop on this topic was held in 2006 in Basel and has shed some light on the current status and the remaining uncertainties of relevance for safety purposes. Also, the workshop highlighted that there is strong interest to continue research in this field. Notably, waste management organisations from France (Finland), Japan, Sweden and Switzerland showed interest to exchange information in this research area on a regular basis and, if possible, advance common projects. Following this workshop, it was decided by Posiva, SKB and Nagra to compile the status of research and development based on a pre-formatted questionnaire sent out to a number of research organisations. This report summarises the information obtained. This serves to identify the remaining knowledge gaps and to explore areas of common interest. Some ideas for common research studies and possibilities how to organise these are presented

    The assessment of the body fluid status is one the most challenging tasks in clinical practice. Although there are many methods to assess the body fluid status of patients, none of them is fully satisfactory in contemporary medical sciences. In the article below, we compare the results of measurements performed by experienced and inexperienced examiners based on the inferior vena cava/aorta diameter index in a sonographic hydration assessment. The study enrolled 50 young students at the age of 19–26 (the median age was 22.95) including 27 women and 23 men. The volunteers were examined in the supine position with GE Logiq 7 system and a convex transducer with the frequency of 2–5 MHz. The measurements were performed in the longitudinal and transverse planes by two inexperienced examiners – the authors of this paper, following a four-hour training conducted by an experienced sonographer. The longitudinal values of the inferior vena cava/aorta diameter index obtained in this study were similar to those found in the literature. The reference value for the inferior vena cava/aorta index determined by Kosiak et al., which constituted 1.2 ± 2 SD, for SD = 0.17, was similar to the values obtained by the authors of this paper which equaled 1.2286 ± 2 SD, for SD = 0.2. The article presented below proves that measuring the inferior vena cava/aorta diameter index is not a complex examination and it may be performed by physicians with no sonographic experience. Furthermore, the paper demonstrates that the inferior vena cava/aorta diameter index measured in the transverse plane is similar to the inferior vena cava/aorta diameter index determined in the longitudinal plane. Thus, both measurements may be used interchangeably to assess the hydration status of patients. PMID:26675322

The measurements were performed in the longitudinal and transverse planes by two inexperienced examiners - the authors of this paper, following a four-hour training conducted by an experienced sonographer. The longitudinal values of the inferior vena cava/aorta diameter index obtained in this study were similar to those found in the literature. The reference value for the inferior vena cava/aorta index determined by Kosiak et al., which constituted 1.2 ± 2 SD, for SD = 0.17, was similar to the values obtained by the authors of this paper which equaled 1.2286 ± 2 SD, for SD = 0.2. The article presented below proves that measuring the inferior vena cava/aorta diameter index is not a complex examination and it may be performed by physicians with no sonographic experience. Furthermore, the paper demonstrates that the inferior vena cava/aorta diameter index measured in the transverse plane is similar to the inferior vena cava/aorta diameter index determined in the longitudinal plane. Thus, both measurements may be used interchangeably to assess the hydration status of patients.

  4. Does excitatory fronto-extracephalic tDCS lead to improved working memory performance? [v1; ref status: indexed, http://f1000r.es/216

    Full Text Available Evidence suggests that excitatory transcranial direct current stimulation (tDCS may improve performance on a wide variety of cognitive tasks. Due to the non-invasive and inexpensive nature of the method, harnessing its potential could be particularly useful for the treatment of neuropsychiatric illnesses involving cognitive dysfunction. However, questions remain regarding the efficacious stimulation parameters. Here, using a double-blind between-subjects design, we explored whether 1 mA excitatory (anodal left dorsolateral prefrontal cortex stimulation with a contralateral extracephalic reference electrode, leads to enhanced working memory performance across two days, relative to sham stimulation. Participants performed the 3-back, a test of working memory, at baseline, and during and immediately following stimulation on two days, separated by 24-48 hours. Active stimulation did not significantly enhance performance versus sham over the course of the experiment. However, exploratory comparisons did reveal a significant effect of stimulation group on performance during the first stimulation phase only, with active stimulation recipients performing better than sham. While these results do not support the hypothesis that dorsolateral prefrontal cortex tDCS boosts working memory, they raise the possibility that its effects may be greatest during early learning stages.

  5. Importance of blood gas measurements in perinatal asphyxia and alternatives to restore the acid base balance status to improve the newborn performance

    Full Text Available Prolonged or intermittent asphyxia in utero and during farrowing weakens piglets and renders them less capable of adaptation to extrauterine life. Piglets with lesser viability at birth have increased blood pCO2 and blood lactic acid concentrations and decreased blood pH. Moreover, the ability to thermoregulate during an acute cold stress is inversely related to umbilical blood lactate concentrations. Blood gas measurements and noninvasive estimations provide important information about oxygenation. The general goals of oxygen therapy in the neonate are to maintain adequate arterial PaO2 and SaO2, and to minimize cardiac work and the work of breathing. Arterial blood gas determinations of pCO2 provide the most accurate determinations of the adequacy of alveolar ventilation. Blood gases obtained in the immediate perinatal period can help assess perinatal asphyxia, but particular attention must be paid to the sampling site, the time of life, and the possible and proven diagnoses. The decision to obtain blood gases must be weighed by the individual clinician against the potential benefits. Current measures for restoring the acid base balance status in the newborn with perinatal asphyxia are discussed.

    This study was conducted to determine the validity of noncognitive and cognitive predictors of the performance of college students at the end of their 4th year in college. Results indicate that the primary predictors of cumulative college grade point average (GPA) were Scholastic Assessment Test/American College Testing Assessment (SAT/ACT) scores and high school GPA (HSGPA) though biographical data and situational judgment measures added incrementally to this prediction. SAT/ACT scores and HSGPA were collected and used in various ways by participating institutions in the admissions process while situational judgment measures and biodata were collected for research purposes only during the first few weeks of the participating students' freshman year. Alternative outcomes such as a self-report of performance on a range of student performance dimensions and a measure of organizational citizenship behavior, as well as class absenteeism, were best predicted by noncognitive measures. The racial composition of a student body selected with only cognitive measures or both cognitive and noncognitive measures under various levels of selectivity as well as the performance of students admitted under these scenarios is also reported. The authors concluded that both the biodata and situational judgment measures could be useful supplements to cognitive indexes of student potential in college admissions.

    Purpose: To examine the effects of deceptively aggressive bike pacing on performance, pacing, and associated physiological and perceptual responses during simulated sprint-distance triathlon. Methods: Ten non-elite, competitive male triathletes completed three simulated sprint-distance triathlons (0.75 km swim, 500 kJ bike, 5 km run), the first of which established personal best “baseline” performance (BL). During the remaining two trials athletes maintained a cycling power output 5% greater than BL, before completing the run as quickly as possible. However, participants were informed of this aggressive cycling strategy before and during only one of the two trials (HON). Prior to the alternate trial (DEC), participants were misinformed that cycling power output would equal that of BL, with on-screen feedback manipulated to reinforce this deception. Results: Compared to BL, a significantly faster run performance was observed following DEC cycling (p triathlon performance to be quicker during DEC (4339 ± 395 s) compared to HON (4356 ± 384 s), the only significant and almost certainly meaningful differences were between each of these trials and BL (4465 ± 420 s; p triathlon run. Conclusions: The present study is the first to show that mid-event pace deception can have a practically meaningful effect on multi-modal endurance performance, though the relative importance of different psychophysiological and emotional responses remains unclear. Whilst our findings support the view that some form of anticipatory “template” may be used by athletes to interpret levels of psychophysiological and emotional strain, and regulate exercise intensity accordingly, they would also suggest that individual constructs such as RPE and affect may be more loosely tied with pacing than previously suggested.

    Pigs (n = 88) weaned at 19 ± 2 d of age were used in a 14-d study to evaluate the effects of water-delivered direct-fed microbials (DFM) or organic acids on growth, immune status, Salmonella infection and shedding, and intestinal microbial populations after intranasal inoculation of Salmonella Typhimurium (10(10) cfu/pig). Pigs were challenged with Salmonella 6 d after commencement of water treatments. Treatments were 1) control diet; 2) control diet + DFM (Enterococcus faecium, Bacillus subtilis, and Bacillus licheniformis) in drinking water at 10(9) cfu/L for each strain of bacteria; 3) control diet + an organic acid-based blend (predominantly propionic, acetic, and benzoic acid) in drinking water at 2.58 mL/L; and 4) control diet + 55 mg/kg of carbadox. Serum samples were taken on d 6, 8, 10, and 14 for determination of tumor necrosis factor α (TNFα) concentrations. Fecal samples were taken on d 0, 5, 7, and 11 for determination of Salmonella shedding and enumeration of coliforms. Pigs were euthanized on d 6, 8, 10, and 14. Intestinal and cecal tissue and digesta and mesenteric lymph nodes were sampled and analyzed for Salmonella. Duodenal, jejunal, and ileal mucosal scrapings were sampled for measurement of mucosal TNFα concentrations. Water delivery of DFM prevented a decline in ADG on d 2 to 6 postchallenge compared with the negative control (P treatment group on d 2 postinfection compared with the negative control and acid treatment groups. However, Salmonella prevalence in the feces, gastrointestinal tract, or lymph nodes was not affected by water delivery of acids or DFM. Serum and mucosal TNFα concentrations were not affected by treatment throughout the study with the exception of ileal concentrations on d 4 postchallenge, which were greater in the negative control group compared with all other treatments (P treatment that reduced Salmonella prevalence and this was localized to the cecum on d 8 postinfection. In conclusion, the DFM and organic acid

    The purpose of this study was to examine the effectiveness of maximal and rapid isometric torque characteristics of the hip extensor muscles and postural balance performance to discriminate between female collegiate soccer athletes and non-athlete controls. Ten athletes (mean ± SE: age = 19·20 ± 0·36 year; mass = 62·23 ± 3·12 kg; height = 162·43 ± 1·70 cm) and 10 non-athletes (age = 20·30 ± 0·40 year; mass = 69·64 ± 3·20 kg; height = 163·22 ± 2·10 cm) performed two isometric maximal voluntary contractions (MVCs) of the hip extensor muscles. Peak torque (PT) and absolute and relative rate of torque development (RTD) at early (0-50 ms) and late (100-200 ms) phases of muscle contraction were examined during each MVC. Postural balance was assessed using a commercially designed balance testing device, which provides a measurement of static stability based on sway index (SI). Results indicated that absolute and relative RTD at 0-50 ms (RTD50 and RTD50norm) were greater (P = 0·007 and 0·026), and postural SI was lower (P = 0·022) in the athletes compared with the non-athletes. However, no differences (P = 0·375-0·709) were observed for PT nor absolute and relative RTD at 100-200 ms (RTD100-200 and RTD100-200norm). Significant relationships were also observed between RTD50 and RTD50norm and SI (r = -0·559 and -0·521; P = 0·010 and 0·019). These findings suggest that early rapid torque characteristics of the hip extensor muscles and postural balance performance may be sensitive and effective measures for discriminating between college-aged athletes and non-athletes. Coaches and practitioners may use these findings as performance evaluation tools to help in identifying athletes with both superior early rapid torque and balance performance abilities, which may possibly be an indicator of overall athletic potential.

    Grape seed extracts (GSE) contain several beneficial bioactive constituents; therefore, can be utilized as a potential feed additive in broiler chickens. An experiment was conducted to investigate the effect of supplementation of broiler chicken diets with GSE as a natural antioxidant at levels of 125, 250, 500, 1000 and 2000 ppm on the growth performance, serum lipid profile, liver glutathione-reduced, thigh muscle malondialdehyde and humoral immune response against Newcastle disease virus vaccines. This experiment was performed during the life-span of chickens from 0 to 42 days of age. The results of broilers fed on diet supplemented by GSE were compared with those fed on the basal diet (control) or the basal diet supplemented by butylated hydroxytoluene as a synthetic antioxidant (BHT, 125 ppm). No significant differences were observed in the growth performance, percent livability, total lipid, high and very low-density lipoprotein cholesterols when the use of GSE or BHT were compared with the control. Total cholesterol and low-density lipoprotein cholesterol were significantly decreased after intake of GSE compared with BHT in the feed diet. The glutathione-reduced level in liver tissues was significantly increased by inclusion of GSE, but not by BHT. Inclusion of GSE or BHT decreased significantly the malondialdehyde level found in meat tissue. The antibody titer against Newcastle disease virus vaccines was significantly elevated in 28 and 35-day-old broiler chickens fed with a diet supplemented with GSE or BHT, the former providing a higher response. It can be concluded that GSE can be used as an effective natural antioxidant and immunostimulant agent in broiler chicken diets, and that 125 to 250 ppm can be considered as the optimum dosage.

    In the present study, the effects of dietary resistant starch (RS) content on serum metabolite and hormone concentrations, milk composition, and faecal microbial profiling in lactating sows, as well as on offspring performance was investigated. Sixteen sows were randomly allotted at breeding to two treatments containing low- and high-RS contents from normal and high-amylose corn varieties, respectively, and each treatment had eight replicates (sows). Individual piglet body weight (BW) and litter size were recorded at birth and weaning. Milk samples were obtained on day 10 after farrowing for composition analysis. On day 2 before weaning, blood and faecal samples were collected to determine serum metabolite and hormone concentrations and faecal microbial populations, respectively. Litter size at birth and weaning were not influenced (p > 0.05) by the sow dietary treatments. Although feeding the RS-rich diet to sows reduced (p = 0.004) offspring birth BW, there was no difference in piglet BW at weaning (p > 0.05). High-RS diet increased (p sows. Feeding the RS-rich diet to sows increased (p sows, as well as a greater nutrient density in maternal milk, without affecting offspring performance at weaning.

    Chinese shrimp Fennerpenaeus chinensis (mean length 1.86 ± 0.15 cm, and weight 137.4 ± 12.7 mg) were reared in the different concentrations of bio-floc (control, 60, 80, 100, 120, and 140%) for 90 days. The growth rate was significantly increased over 100% bio-floc concentrations. In the immunological parameters, the gene expression of proPO and lysozyme was considerably increased over 120% bio-floc concentrations. The gene expression of SP was notably elevated at 140% bio-floc concentration. In the antioxidant enzymes, the activity of SOD was considerably decreased over 80% bio-floc concentrations. A notable decline in the activity of CAT was observed over 120% bio-floc concentrations. The results indicate that rearing of Chinese shrimp in bio-floc system can induce the increase of growth performance, enhancement of immune responses, and reduction of oxidative stress.

    Canine parvovirus (CPV) is one of the most common causes of acute haemorrhagic enteritis in young dogs, while clinical diagnosis is often indecisive. The aim of our study was to evaluate the diagnostic accuracy of an in-clinic rapid test in the detection of CPV infection in dogs. To this end, we compared the Rapid Diagnostic Kit of Canine Parvovirus, Coronavirus and Rotavirus antigen (Quicking(®)) to PCR, which is considered as the most reliable diagnostic method. A total of 78 duplicated faecal samples were collected from diarrhoeic dogs. Vaccination history within a month prior to the onset of diarrhoea was reported for 12 of the sampled dogs. The rapid diagnostic test was performed in 23 of the faecal samples directly, while the rest were placed into a sterile cotton tipped swab suitable for collection and transportation of viruses (Sigma Σ-VCM(®)) and stored at -20 °C. The sensitivity of the Quicking rapid diagnostic test compared to PCR in the total number of samples, in samples from non-vaccinated dogs and in samples tested directly after collection were 22.22% (95% CI: 13.27-33.57%), 26.67% (95% CI: 16.08-39.66%) and 76.47% (95% CI: 50.10-93.04%) respectively, while the specificity of the test was 100% in any case. In conclusion, negative results do not exclude parvoenteritis from the differential diagnosis, especially in dogs with early vaccination history, but a positive result almost certainly indicates CPV infection. An improved sensitivity may be expected when the test is performed immediately.

    The effects of a pre-formulated commercial plant extract mix, composed of equal parts of oregano essential oil and sweet chestnut wood extract, on performance, oxidative status and pork quality traits were evaluated. In two 155-d studies, 60 pigs (mean liveweight: 42.9 kg) were assigned to either a control diet (CTR) or an identical diet supplemented (0.2%) with the plant extract mix (OC). No differences in the growth rate were observed. Glutathione peroxidase and glutathione reductase activities in the OC muscles (Longissimus lumborum) were higher than in CTR muscles. The lipid oxidation of meat was lower in the OC group. In the cooked meat samples, OC animals had the lowest L* and H° values and the highest a* values. The OC meat received higher scores for colour, taste and overall liking in both the blind and the labelled consumer tests.

    This study explored the effects of supplemental dietary extra virgin olive oil (EVOO), gallic acid (GA), or lemongrass essential oil (LGEO) on growth performance, nutrient digestibility, carcass traits, lipid peroxidation, hematological, and antioxidative status in growing rabbits under heat stress conditions. A total of 48 male growing New Zealand White rabbits were randomly divided into four equal groups, which received a basal diet without any supplementation or supplemented with 15 g EVOO, 500 mg GA, or 400 mg LGEO/kg of diet, for eight consecutive weeks. Results revealed that the overall mean of temperature humidity index was 84.67 ± 0.35, reflecting a state of severe heat stress. Moreover, dietary supplementation with EVOO, GA, or LGEO significantly increased live body weight and daily body weight gain but decreased both feed conversion ratio and daily water consumption. Additionally, a significant increase in both organic matter and crude protein digestibility besides a remarkable elevation in the nutritive values of digestible crude protein, total digestible nutrients, and digestible energy, as well as an increase in the numbers of WBCs, lymphocytes, and heterophils was significant in EVOO-supplemented rabbits. Supplementation with EVOO, GA, or LGEO in the heat-stressed growing rabbit's diet enhanced catalase activity and reduced glutathione content, whereas EVOO-treated rabbits had the highest values. Also, malondialdehyde activity was reduced in response to all tested additives. In conclusion, these findings suggested that addition of EVOO, GA, or LGEO in growing rabbit's diet could be used effectively to alleviate negative impacts of heat stress load on performance, nutrient digestibility, oxidative status, and hemato-biochemical features. Furthermore, among these additives, EVOO achieved the best effects.

    2009-01-01

    We are constructing a Silicon Vertex Tracker detector (VTX) for the PHENIX experiment at RHIC. Our main motivation is to enable measurements of heavy flavor production (charm and beauty) in p+p, p+d and A+A collisions. Such data will illuminate the properties of the matter created in high-energy heavy-ion collisions. The measurements also will reveal the distribution of gluons in protons from p+p collisions. The VTX detector consists of four layers of barrel detectors and covers |eta|< 1.2, and almost a 2pi in azimuth. The inner two silicon barrels consist of silicon pixel sensors; their technology accords with that of the ALICE1LHCB sensor-readout hybrid. The outer two barrels are silicon stripixel detectors with a new "spiral" design, and a single-sided sensor with 2-dimensional (X, U) readout. In this paper, we describe the silicon stripixel detector and discuss its performance, including its response to electrons from a beta source (90Sr), muons from cosmic-rays, and a 120 GeV proton beam. The results ...

    The Virgo collaboration has just concluded its first long science run (VSR1). In these four months the detector achieved a good duty cycle, larger than 80%, and an average horizon distance for binary neutron star system sources of about 4 Mpc. An intense commissioning activity was resumed after the run was complete to further increase the performances of the detector and to prepare the Virgo+ upgrades. The detector performances during the first science run and the last commissioning achievements are briefly discussed here.

  11. Effects of prior testing lasting a full year in NCANDA adolescents: Contributions from age, sex, socioeconomic status, ethnicity, site, family history of alcohol or drug abuse, and baseline performance

    Full Text Available Longitudinal study provides a robust method for tracking developmental trajectories. Yet inherent problems of retesting pose challenges in distinguishing biological developmental change from prior testing experience. We examined factors potentially influencing change scores on 16 neuropsychological test composites over 1 year in 568 adolescents in the National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA project. The twice-minus-once-tested method revealed that performance gain was mainly attributable to testing experience (practice with little contribution from predicted developmental effects. Group mean practice slopes for 13 composites indicated that 60% to ∼100% variance was attributable to test experience; General Ability accuracy showed the least practice effect (29%. Lower baseline performance, especially in younger participants, was a strong predictor of greater gain. Contributions from age, sex, ethnicity, examination site, socioeconomic status, or family history of alcohol/substance abuse were nil to small, even where statistically significant. Recognizing that a substantial proportion of change in longitudinal testing, even over 1-year, is attributable to testing experience indicates caution against assuming that performance gain observed during periods of maturation necessarily reflects development. Estimates of testing experience, a form of learning, may be a relevant metric for detecting interim influences, such as alcohol use or traumatic episodes, on behavior.

    Full Text Available Six hundred 1-d-old male broilers (Ross 308 were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril, 15, 30 and 60 ppm enalapril in the drinking water. From d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. Mortalities were inspected to determine the cause of death and diagnose of ascites. At the end of the experiment (wk 7, 2 chickens from each replicate were randomly selected and slaughtered. Body weight gain, feed intake and feed conversion ratio were calculated. Plasma protein, glucose, red blood cell, white blood cell, triglyceride, high-density lipoprotein, malondialdehyde, the activity of alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, creatine kinase, total antioxidant capacity, superoxide dismutase, and glutathione peroxidase were also determined. Results showed that enalapril for 30 and 60 ppm, significantly improved feed conversion ratio and enhanced body weight gain when measured at day 49. These levels of enalapril compared to the other groups, significantly reduced malondialdehyde level and glutathione peroxidase activity, but increased total antioxidant capacity and superoxide dismutase activity in plasma. Moreover, enalapril at levels of 30 and 60 ppm, significantly reduced aspartate aminotransferase, alkaline phosphatase and creatine kinase activities in plasma. Mortality due to ascites and right to total ventricular weight ratio were significantly low in groups received enalapril at greater levels (≥30 ppm. Compared to the control, enalapril increased high-density lipoprotein. In conclusion, enalapril could improve growth performance and reduced mortality in broilers.

    Non-saleable milk (waste milk, WM) is contaminated with an undefined spectrum of potentially harmful pathogens and antimicrobial residues. The objective of this study was to determine the impact of feeding bulk milk (BM) or WM - both pasteurized or not - on calf performance, health and the antibiotic resistance of specific faecal bacteria. A total of 114 calves from a large-scale dairy were housed outdoors in individual hutches and were randomly assigned to one of four feeding groups. The calves were fed either WM, pasteurized WM (pWM), BM or pasteurized BM (pBM) from day 3 to 56 of life. Milk samples taken from the pasteurizer and calves' nipple buckets were investigated at regular intervals for total plate count and counts of thermoduric bacteria, coliforms and mastitis pathogens. Faecal samples were taken on days 2, 14, 28 and 56 of life from randomly selected calves of the WM, pWM and BM groups (each N = 8-9) and processed to obtain from each sample preferably two isolates of Escherichia (E.) coli and Enterococcus spp. respectively. Isolates were tested for their antimicrobial susceptibility to 25 antimicrobial agents by broth microdilution. Daily weight gain, milk and calf starter intake and health parameters did not differ significantly between the calves of the four feeding groups. The proportion of resistant E. coli isolates was significantly higher in calves fed WM and in calves fed pWM (most pronounced for cephalosporins) than in calves receiving BM. No differences in resistance were found for Enterococus spp. Thus, the concerns for selecting resistant faecal bacteria by feeding WM seem to be justified. Nonetheless, pasteurized WM of cows not treated with antimicrobials represents an acceptable feed for young calves.

    One experiment was conducted to evaluate the influence of glycerin (GLY) on animal performance and health when used as a partial replacement for roughage in receiving diets. The second experiment was conducted using ruminally and duodenally cannulated steers in a 4 × 4 Latin square to determine the site of nutrient digestion and ruminal fermentation characteristics when GLY replaced roughage at 0%, 2.5%, 5%, and 10% of diet DM. In Exp. 1, steers (initial BW = 245 ± 2.3 kg) were fed treatment diets over a 42-d period that consisted of a control diet based on steam-flaked corn with GLY inclusion in replacement of dietary roughage at 0%, 5%, and 10% of diet DM. A linear reduction in DMI was observed as GLY increased (P = 0.01). Glycerin incorporation tended to improve G:F in a linear manner (P = 0.07); efficiency was improved 5.4% and 4.7% at 5% and 10% GLY. The number of animals receiving treatment for bovine respiratory disease did not differ among treatments. Furthermore, there were no differences among treatments for mortality or the frequency of steers that were seropositive for serum antibody titers to infectious bovine rhinotracheitis on d 28. In Exp. 2, apparent OM and apparent and true starch digestibility increased linearly (P < 0.05) as GLY concentration increased, whereas true OM digestibility responded in a quadratic (P < 0.01) manner. Bacterial OM and bacterial starch flow responded quadratically (P ≤ 0.02), and flow increased from 0% to 5% GLY inclusion and decreased thereafter. Feed OM flow responded quadratically (P ≤ 0.05), where it decreased from 0% to 2.5% GLY and increased from 2.5% to 10% GLY inclusion. Feed starch (P = 0.02) and total starch (P = 0.02) flow from the duodenum decreased linearly as the concentration of GLY increased in the diet. Bacterial N flow to the duodenum responded quadratically (P < 0.01); it increased with increasing GLY in the diet up to 5% and then decreased from 5% to 10%. The acetate to propionate (A:P) ratio in

    Effects of grain type and dietary oil supplement on production performance, energy balance, metabolic heat production, and markers of liver function of heat-loaded lactating dairy cows were evaluated using 8 multiparous Holstein cows (77.0d in milk) in a duplicated 4×4 Latin square design with a 2×2 factorial arrangement of treatments. Experimental diets contained either ground barley or ground corn supplemented with either fish oil or soybean oil at 2% of dietary dry matter. Mean daily maximum temperature, minimum relative humidity, and maximum temperature-humidity index were 35.3°C, 11.3%, and 77.0, respectively. Dietary treatment did not affect rectal temperature (38.9°C), but respiration rate tended to decrease in cows fed fish oil versus soybean oil. Dry matter intake decreased for the fish oil-supplemented diets (21.1 vs. 24.3kg/d), which was negatively correlated with plasma concentrations of alkaline phosphatase (r=-0.45; n=32) and malondialdehyde (r=-0.26; n=32). Actual milk yield (41.9kg/d) and energy-corrected milk yield (36.6kg/d) were not affected by grain type, whereas feeding fish oil decreased milk yield as compared with soybean oil (40.4 vs. 43.4kg/d). Milk fat depression occurred in all dietary treatments, especially when cows were fed fish oil because of the presence of polyunsaturated FA in the diets. trans-10 C18:1 was negatively correlated with milk fat yield (r=-0.38; n=32). Daily milk cis-9,trans-11 C18:2 secretion was 29.6% less in cows fed barley- versus corn-based diets but 31.8% greater in cows fed fish oil as compared with cows fed soybean oil. Because of a lower dry matter intake, metabolic heat production was decreased in cows fed fish oil relative to cows fed soybean oil. Although feeding fish oil versus soybean oil decreased net energy for both maintenance and lactation, net energy balance remained unchanged across treatments. In vivo plasma lipoperoxidation was greater in cows fed fish oil versus soybean oil, which

    Background The phase III RAINBOW trial demonstrated that the addition of ramucirumab to paclitaxel improved overall survival, progression-free survival, and tumor response rate in fluoropyrimidine–platinum previously treated patients with advanced gastric/gastroesophageal junction (GEJ) adenocarcinoma. Here, we present results from quality-of-life (QoL) and performance status (PS) analyses. Patients and methods Patients with Eastern Cooperative Oncology Group PS of 0/1 were randomized to receive ramucirumab (8 mg/kg i.v.) or placebo on days 1 and 15 of a 4-week cycle, with both arms receiving paclitaxel (80 mg/m2) on days 1, 8, and 15. Patient-reported outcomes were assessed with the QoL/health status questionnaires EORTC QLQ-C30 and EQ-5D at baseline and 6-week intervals. PS was assessed at baseline and day 1 of every cycle. Time to deterioration (TtD) in each QLQ-C30 scale was defined as randomization to first worsening of ≥10 points (on 100-point scale) and TtD in PS was defined as first worsening to ≥2. Hazard ratios (HRs) for treatment effect were estimated using stratified Cox proportional hazards models. Results Of the 665 patients randomized, 650 (98%) provided baseline QLQ-C30 and EQ-5D data, and 560 (84%) also provided data from ≥1 postbaseline time point. Baseline scores for both instruments were similar between arms. Of the 15 QLQ-C30 scales, 14 had HR < 1, indicating similar or longer TtD in QoL for ramucirumab + paclitaxel. Treatment with ramucirumab + paclitaxel was also associated with a delay in TtD in PS to ≥2 (HR = 0.798, P = 0.0941). Alternate definitions of PS deterioration yielded similar results: PS ≥ 3 (HR = 0.656, P = 0.0508), deterioration by ≥1 PS level (HR = 0.802, P = 0.0444), and deterioration by ≥2 PS levels (HR = 0.608, P = 0.0063). EQ-5D scores were comparable between treatment arms, stable during treatment, and worsened at discontinuation. Conclusion In patients with previously treated advanced gastric

    Entrepreneurship has become more and more important with the development of economic diversification and challenges of employment pressure in China.Based on the network-based perspective of entrepreneurial research and social stratification the-ory, this study explores the“liability of newness” in the Chinese context and social capital effects on the long-run performance of new ventures.Many empirical studies find social capitals of founders influence the survival of a new venture, yet we know little about the moderate effects of initial social status of the founder, especially social status obtained from parents and founder him-self.From the network-based perspective of entrepreneurship, we propose that social capitals from the egocentric networks of founders can affect new venture performance , yet are moderated by initial social status. We classify social networks of founders into four types by strengths ( strong ties or weak ties) and functions ( bridging or bonding functions) , and measure initial social status by occupational prestige of founder himself and his parents before new ven-ture startup.We firstly obtain a lists of new venture firms from famous business journal of China in 1978-1999, then code data manually of randomly selected 182 founders in the lists.Finally we analyze different effects of social capitals and initial social status on the long-run performance by using logistic regression and Cox proportional hazards models simultaneously to check the robustness of the results. Most of the hypotheses are supported by empirical results, which implies social status of founder himself is a signal of entre-preneurial commitment, and strengthens the positive effects of social capital on new venture performance.However, parents′oc-cupational prestige may be contaminated by bias against commerce of traditional Chinese culture or socialist ideology, and chan-ges contents and mechanism of egocentric network.Hence it brings in negative effects on

    The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities. The Model Validation Status Review emphasized those AMRs that support TSPA-SR (CRWMS M&O 2000bl and 2000bm). A series of workshops and teleconferences was held to discuss and integrate the review findings. The review encompassed 125 AMRs (Table 1) plus certain other supporting documents and data needed to assess model validity. The AMRs were grouped in 21 model areas representing the modeling of processes affecting the natural and

    FAZIA is designed for detailed studies of the isospin degree of freedom, extending to the limits the isotopic identification of charged products from nuclear collisions when using silicon detectors and CsI(Tl) scintillators. We show that the FAZIA telescopes give isotopic identification up to Z~25 with a ΔE-E technique. Digital Pulse Shape Analysis makes possible elemental identification up to Z=55 and isotopic identification for Z=1-10 when using the response of a single silicon detector. The project is now in the phase of building a demonstrator comprising about 200 telescopes.

    Benchmark results of the Dutch PINK working group on calculational benchmarks on single pin cell and multipin assemblies as defined by EPRI are presented and evaluated. First a short update of methods used by the various institutes involved is given as well as an update of the status with respect to previous performed pin-cell calculations. Problems detected in previous pin-cell calculations are inspected more closely. Detailed discussion of results of multipin assembly calculations is given. The assembly consists of 9 pins in a multicell square lattice in which the central pin is filled differently, i.e. a Gd pin for the BWR assembly and a control rod/guide tube for the PWR assembly. The results for pin cells showed a rather good overall agreement between the four participants although BWR pins with high void fraction turned out to be difficult to calculate. With respect to burnup calculations good overall agreement for the reactivity swing was obtained, provided that a fine time grid is used. (orig.)

    Cytotoxic chemotherapy remains the core treatment strategy for patients with advanced non-small cell lung cancer (NSCLC) with tumours that do not have actionable molecular alterations, such as epidermal growth factor receptor (EGFR)-sensitising mutations, anaplastic lymphoma kinase (ALK) translocations or ROS1 translocations. Age and performance status (PS) are two pivotal factors to guide treatment decisions regarding the use of chemotherapy in lung cancer patients. Lung cancer is predominantly a disease of the elderly, with more than two-thirds of patients aged ≥65 years, the current definition of 'elderly'. The prevalence of poor PS, as estimated by patients themselves, can be as high as 50%. Both the elderly and PS2 patients are underrepresented in clinical trials. Therefore, optimising treatment strategy for the subgroup of elderly or PS2 patients with advanced NSCLC remains challenging as a result of a paucity of clinical trial data. The current review focusses on the elderly or PS2 patients without actionable oncogenic drivers and attempts to summarise current available data on recent treatments trials including angiogenesis inhibitors and immune-checkpoint inhibitors.

    Exogenous alanyl-glutamine (Aln-Gln) was evaluated for its effects on growth performance, intestinal structure and function, antioxidant status and non-specific immunity of young carp (Cyprinus carpio L.). Six diets supplemented with 0, 2.5, 5.0, 7.5, 10.0, or 15.0 g• kg-1 of Aln-Gln were fed to fish for 12 weeks. Supplementation with 7.5, 10.0, or 15.0 g• kg-1 of Aln-Gln significantly increased weight gain rate (WGR), protein efficiency ratio (PER), but feed conservation rate (FCR) and survival were not affected (P>0.05). The intestinal fold height and number, digestive enzyme, Na+, K+-ATPase activities was found to be significantly high (P<0.05) with increasing dietary Aln-Gln supplementation up to 7.5 g• kg-1, but there were no significant differences for Aln-Gln supplementation from 7.5 to 15.0 g• kg-1. The glutathione peroxidase (GPX) activity, glutathione (GSH), superoxide dismutase (SOD) activity increased and malondialdehyde (MDA) levels decreased significantly (P<0.05) in the intestine, hepatopancreas, plasma and muscles. The plasma complement-3 (C3) and complement-4 (C4) levels were significantly (P<0.05) improved at 5.0 g• kg-1 level and decreased when over 7.5 g• kg-1. The plasma lysozyme (LSZ) activity increased significantly (P<0.05) at 7.5, 10.0, or 15.0 g• kg-1level. In summary, the results showed that Aln-Gln improved growth performance, development and function of the intestine, the activity of the antioxidant defense system and the plasma non-specific immunity of the carps. The optimal Aln-Gln level was 8.24 g• kg-1 diet for WGR based on broken-line regression model analysis.

    The development of the Advanced Life Support (ALS) Sizing Analysis Tool (ALSSAT) using Microsoft(Registered TradeMark) Excel was initiated by the Crew and Thermal Systems Division (CTSD) of Johnson Space Center (JSC) in 1997 to support the ALS and Exploration Offices in Environmental Control and Life Support System (ECLSS) design and studies. It aids the user in performing detailed sizing of the ECLSS for different combinations of the Exploration Life support (ELS) regenerative system technologies. This analysis tool will assist the user in performing ECLSS preliminary design and trade studies as well as system optimization efficiently and economically. The latest ALSSAT related publication in ICES 2004 detailed ALSSAT s development status including the completion of all six ELS Subsystems (ELSS), namely, the Air Management Subsystem, the Biomass Subsystem, the Food Management Subsystem, the Solid Waste Management Subsystem, the Water Management Subsystem, and the Thermal Control Subsystem and two external interfaces, including the Extravehicular Activity and the Human Accommodations. Since 2004, many more regenerative technologies in the ELSS were implemented into ALSSAT. ALSSAT has also been used for the ELS Research and Technology Development Metric Calculation for FY02 thru FY06. It was also used to conduct the Lunar Outpost Metric calculation for FY08 and was integrated as part of a Habitat Model developed at Langley Research Center to support the Constellation program. This paper will give an update on the analysis tool s current development status as well as present the analytical results of one of the trade studies that was performed.

    As survival with pediatric left ventricular assist devices (LVADs) has improved, decisions regarding the optimal support strategy may depend more on quality of life and functional status (FS) rather than mortality alone. Limited data are available regarding the FS of children supported with LVADs. We sought to compare the FS of children supported with LVADs vs vasoactive infusions to inform decision making around support strategies. Organ Procurement and Transplant Network data were used to identify all United States children aged between 1 and 21 years at heart transplant (HT) between 2006 and 2015 for dilated cardiomyopathy and supported with an LVAD or vasoactive infusions alone at HT. FS was measured using the 10-point Karnofsky and Lansky scale. Of 701 children who met the inclusion criteria, 430 (61%) were supported with vasoactive infusions, and 271 (39%) were supported with an LVAD at HT. Children in the LVAD group had higher median FS scores at HT than children in the vasoactive infusion group (6 vs 5, p < 0.001) but lower FS scores at listing (4 vs 6, p < 0.001). The effect persisted regardless of patient location at HT (home, hospital, intensive care) or device type. Discharge by HT occurred in 46% of children in the LVAD group compared with 26% of children in the vasoactive infusion cohort (p = 0.001). Stroke was reported at HT in 3% of children in the LVAD cohort and in 1% in the vasoactive infusion cohort (p = 0.04). Among children with dilated cardiomyopathy undergoing HT, children supported with LVADs at HT have higher FS than children supported with vasoactive infusions at HT, regardless of device type or hospitalization status. Children supported with LVADs at HT were more likely to be discharged from the hospital but had a higher prevalence of stroke at HT.

    Refractory status epilepticus (RSE) has a high morbidity and mortality. There are currently no definitive data to guide both the optimal choice of therapy and treatment goals. This review focuses on RSE diagnosis and outcome and discusses both commonly used and anecdotal therapies for RSE. The challenges in performing randomized controlled trials (RCTs) in neurocritical care and more specifically for the treatment of RSE are illustrated by the early termination of the first RCT of RSE due to low recruitment that compared propofol to barbiturates. Recent case series include the successful treatment of recurrent RSE with ketamine, intravenous lacosamide as an add-on treatment, the use of combination antiepileptics (phenytoin, levetiracetam, and pregabalin), and surgical treatments (vagal nerve and deep brain stimulation) for the control of RSE. A number of different therapeutic options are available for the treatment of RSE but none have been shown to be superior to others at this point.

    Fe and n-3 long-chain PUFA (n-3 LCPUFA) have both been associated with cognition, but evidence remains inconclusive in well-nourished school-aged children. In the Optimal Well-Being, Development and Health for Danish Children through a Healthy New Nordic Diet (OPUS) School Meal Study, the 3-month intervention increased reading performance, inattention, impulsivity and dietary intake of fish and Fe. This study investigated whether the intervention influenced n-3 LCPUFA and Fe status and, if so, explored how these changes correlated with the changes in cognitive performance. The study was a cluster-randomised cross-over trial comparing school meals with packed lunch (control). At baseline and after each treatment, we measured serum ferritin, whole-blood n-3 LCPUFA and Hb, and performance in reading, mathematics and d2-test of attention. Data were analysed using mixed models (n 726) and principal component analysis of test performances (n 644), which showed two main patterns: 'school performance' and 'reading comprehension'. The latter indicated that children with good reading comprehension were also more inattentive and impulsive (i.e. higher d2-test error%). The intervention improved 'school performance' (P=0·015), 'reading comprehension' (P=0·043) and EPA+DHA status 0·21 (95% CI 0·15, 0·27) w/w % (Preading comprehension' in both boys and girls. Both baseline EPA+DHA status and the intervention-induced increase in EPA+DHA status was positively associated with 'school performance', suggesting that n-3 LCPUFA could potentially explain approximately 20 % of the intervention effect. These exploratory associations indicate that increased fish intake might explain some of the increase in reading performance and inattention in the study.

    Hemodialysis has a major influence on the quality of life of chronic renal failure patients. Great attention is currently paid to the development of supporting programmes for this patient group. Aim of this study was to evaluate the quality of life in maintenance dialysis and to research the influence of various factors related to treatment and ESRD on quality of life, taking into account also the level of school instruction. Reduced functional abilities, as measured by the Sickness Impact Profile (SIP), and Functional Living Test (FLT), derived by Karnofsky Activity Scale were assessed; Hospital Anxiety and Depression Scale (HAD) and semistructured interviews, including a clinical grading of symptoms were considered vs. age, duration of dialysis, level of school instruction. The study was performed with 40 hemodialysis patients, aged 57.4 +/- 14.9 years (range 22-79), treated since at least three years. Significant (P higher SIP scores (greater disability) and Functional Living Test were lower educational level, and the score of Hospital Anxiety and Depression Scale (HAD). No correlation was found for any of the three scales vs. age and vs. dialytic age; no gender difference was observed. A greater care in considering Quality of Life questionnaires is warranted, especially for the severe interference of instruction level of patients on results. QALY (Quality Adjusted Life Years), used as a tool for decision-making in clinical and political subsets, can include critical bias that invalidate conclusion.

  13. When do low status individuals accept less? The interaction between self- and other-status during resource distribution

    Full Text Available In real-world social interactions, social status influences responses to resource distribution. However, the way in which one’s own social status interacts with another’s status to influence responses to resource distribution is far from clear. In the current study, we dynamically manipulated participants’ social status and then asked participants to act as recipients in the ultimatum game (UG along with proposers whose social status was made known to the participants. Experiment 1 used a between-participants design in which the participants were assigned as being of either high or low status according to their performance in a math competition (i.e., rank-inducing task. In Experiment 2, social status was manipulated within-subjects using the same rank-inducing task, with rounds of UG interleaved between rank-inducing sessions. Findings from the two experiments showed that both self-status and other-status influenced responses to UG offers, as participants were more likely to accept low offers from high status than low status proposers; this effect was particularly robust for low status participants when compared with high status participants. These findings suggest that, in comparison with individuals in high status, individuals in low status are more willing to accept low offers during resource distribution and are more affected by other-status considerations.

The applica tion status of alloys for high performance and advanced naval vessels are introduced. It is showed that HSLA microal-loyed high strength steel developed by USA through the method of high purity metallurgy and TMCP technology re presents the highest level of steel designed for ship hull and deck. Most countries still use HY-80 and HY-100 high yield steel to build their ship. Applied technologies of naval vessel, such as titanium alloy and high strengh low mag netic steel of Russia and Germany,respectively, have reached international advanced standards,while the United States and Russia are advanced in the application of ship structure of the aluminum alloy. The copper-nickels containing iron are most used in condense pipe of vessels. Compared with other alloys, titanium alloy is the best alloy used for not only ship condensator, but also piping and propeller. Today, light weight, high strengh and low cost are important basis when selecting alloys for vessel design.

    The French-Italian interferometric gravitational wave detector VIRGO is currently being commissioned. Its principal instrument is a Michelson interferometer with 3 km long optical cavities in the arms and a power-recycling mirror. This paper gives an overview of the present status of the system. We report on the presently attained sensitivity and the system's performance during the recent commissioning runs. After a sequence of intermediate stages, the interferometer is now being used in the so-called recombined configuration. The input laser beam is spatially filtered by a 144 m long input mode-cleaner before being injected to the main interferometer. The main optics are suspended from so-called \\sa s, which provide an excellent seismic isolation. The two 3 km long Fabry-Perot arm cavities are kept in resonance with the laser light, and the Michelson interferometer is held on the dark fringe. An automatic mirror alignment system based on the Anderson technique has been implemented for the arm cavities. The l...

    ANAIS experiment will look for dark matter annual modulation with large mass of ultra-pure NaI(Tl) scintillators at the Canfranc Underground Laboratory (LSC), aiming to confirm the DAMA/LIBRA positive signal in a model-independent way. Two 12.5 kg each NaI(Tl) crystals provided by Alpha Spectra are currently taking data at the LSC. Present status of ANAIS detectors background and general performance is summarized; in particular, thanks to the high light collection efficiency prospects of lowering the threshold down to 1 keVee are reachable. Crystal radiopurity goals are fulfilled for $^{232}$Th and $^{238}$U chains and $^{40}$K activity, although higher than original goal, could be accepted; however, high $^{210}$Pb contamination out-of-equilibrium has been identified. More radiopure detectors are being built by Alpha Spectra. The ongoing high quantum efficiency PMT tests and muon veto characterization are also presented. Finally, the sensitivity of the experiment for the annual modulation in the WIMP signal,...

    Full Text Available BACKGROUND: Hypothesizing that nutritional status, systemic inflammation and tumoral immune microenvironment play a role as determinants of lung cancer evolution, the purpose of this study was to assess their respective impact on long-term survival in resected non-small cell lung cancers (NSCLC. METHODS AND FINDINGS: Clinical, pathological and laboratory data of 303 patients surgically treated for NSCLC were retrospectively analyzed. C-reactive protein (CRP and prealbumin levels were recorded, and tumoral infiltration by CD8+ lymphocytes and mature dendritic cells was assessed. We observed that factors related to nutritional status, systemic inflammation and tumoral immune microenvironment were correlated; significant correlations were also found between these factors and other relevant clinical-pathological parameters. With respect to outcome, at univariate analysis we found statistically significant associations between survival and the following variables: Karnofsky index, American Society of Anesthesiologists (ASA class, CRP levels, prealbumin concentrations, extent of resection, pathologic stage, pT and pN parameters, presence of vascular emboli, and tumoral infiltration by either CD8+ lymphocytes or mature dendritic cells and, among adenocarcinoma type, tumor grade (all p285 mg/L prealbumin levels and high (>96/mm2 CD8+ cell count had a 5-year survival rate of 80% [60.9-91.1] as compared to 18% [7.9-35.6] in patients with an opposite pattern of values. When stages I-II were considered alone, the prognostic significance of these factors was even more pronounced. CONCLUSIONS: Our data show that nutrition, systemic inflammation and tumoral immune contexture are prognostic determinants that, taken together, may predict outcome.

    Status Dystonicus is a rare complication of dystonia. It is a life threatening disorder that needs urgent treatment.The aim of this study is to describe clinical features, management and follow up of children with Status Dystonicus. - We conducted a retrospective study over an 8-year period including all patients diagnosed with Status Dystonicus. Clinical characteristics, etiologies and management were analyzed. - Ten patients were included. Main features of Status Dystonicus were a severe generalized dystonia with vegetative signs. Laryngeal spasm and swallowing disorders were observed in 4 cases. Several treatments such as Levodopa, Anticholinergics, Baclofen, Benzodiazepines and Neuroleptics were tried. Mechanical ventilation was required in 4 cases. Two patients died due to rhabdomyolysis and respiratory failure. Others returned to their pre-Status Dystonicus. - Status Dystonicus is a life threatening condition that needs an urgent management on an intensive care unit. In fact, patients with Status Dystonicus can develop respiratory failure and metabolic complications.On the basis of our experience, we delineated a therapeutic approach in which the patient with Status Dystonicus needs supportive care, specific therapy of dystonia and intravenous sedative treatment.

    The effect of inorganic (INORG) or organic (ORG) Cu, fed without (-) or with (+) additional S and Mo on Cu status and performance was examined using 56 early lactation dairy cows in a 2×2 factorial study design. Supplementary Cu was added as either CuSO4 or BioplexCu (Alltech Inc., Nicholasville, KY) to provide an additional 10mg of Cu/kg of dry matter (DM), with S added at 1.5g/kg of DM and Mo at 6.8mg/kg of DM to reduce Cu bioavailability. The basal ration was composed of corn and grass silages (2:1 respectively, DM basis) and straight feeds. Cows commenced the study at wk 7 of lactation and remained on treatment for 16 wk. An interaction existed between Cu source and added S and Mo on DM intake, with cows offered INORG- Cu having an increased intake compared with those offered INORG+ or ORG- Cu. Milk yield averaged 35.4kg/d, and was 5% higher with milk fat content 6% lower in cows fed INORG compared with ORG Cu, but milk fat yield, energy-corrected milk yield, and milk protein content did not differ between treatments. A trend existed for cows to have a higher body weight gain when offered ORG compared with INORG Cu. Cows fed diets containing INORG Cu had a higher milk concentration of C17:0 and C18:3n-3 compared with those fed diets containing ORG Cu. Cows fed added S and Mo had a lower milk concentration of C17:0 and C18:0 compared with those that were not supplemented. No effect was observed of dietary treatment on plasma Cu concentration, which averaged 13.1 µmol/L, except during wk 12 when cows receiving added S and Mo had a lower concentration. No effect was observed of Cu source on mean plasma Mo concentrations, but during wk 16 cows offered INORG Cu had a higher concentration than those offered ORG Cu. Hepatic Cu levels decreased by approximately 0.9mg/kg of DM per day when fed additional S and Mo, but no effect of Cu source was observed. A trend existed for hepatic ATPase, Cu++ transporting, beta polypeptide (ATP7B) to be upregulated in cows when fed

  11. Status epilepticus in adults.

    Science.gov (United States)

    Betjemann, John P; Lowenstein, Daniel H

    2015-06-01

    Status epilepticus is a common neurological emergency with considerable associated health-care costs, morbidity, and mortality. The definition of status epilepticus as a prolonged seizure or a series of seizures with incomplete return to baseline is under reconsideration in an effort to establish a more practical definition to guide management. Clinical research has focused on early seizure termination in the prehospital setting. The approach of early escalation to anaesthetic agents for refractory generalised convulsive status epilepticus, rather than additional trials of second-line anti-epileptic drugs, to avoid neuronal injury and pharmaco-resistance associated with prolonged seizures is gaining momentum. Status epilepticus is also increasingly identified in the inpatient setting as the use of extended electroencephalography monitoring becomes more commonplace. Substantial further research to enable early identification of status epilepticus and efficacy of anti-epileptic drugs will be important to improve outcomes.

    In patients with head and neck and esophageal tumors, nutritional status may deteriorate during concurrent chemoradiotherapy (CRT). The aim of this study was to investigate the influence of enteral nutrition enriched with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on body composition and nutritional and functional status. In a controlled, randomized, prospective, double-blind, multicenter study, 111 patients with head and neck and esophageal cancer undergoing concurrent CRT received either an enteral standard nutrition (control group) or disease-specific enteral nutrition Supportan®-containing EPA+DHA (experimental group) via percutaneous endoscopic gastrostomy. The primary endpoint was the change of body cell mass (BCM) following CRT at weeks 7 and 14 compared with the baseline value. Secondary endpoints were additional parameters of body composition, anthropometric parameters, and nutritional and functional status. The primary endpoint of the study, improvement in BCM, reached borderline statistical significance. Following CRT, patients with experimental nutrition lost only 0.82 ± 0.64 kg of BCM compared with 2.82 ± 0.77 kg in the control group (P = .055). The objectively measured nutritional parameters, such as body weight and fat-free mass, showed a tendency toward improvement, but the differences were not significant. The subjective parameters, in particular the Kondrup score (P = .0165) and the subjective global assessment score (P = .0065) after follow-up improved significantly in the experimental group, compared with the control group. Both enteral regimens were safe and well tolerated. Enteral nutrition with EPA and DHA may be advantageous in patients with head and neck or esophageal cancer by improving parameters of nutritional and functional status during CRT. © 2013 American Cancer Society.

    Full Text Available Le paradigme du développement dans les Petites Economies Insulaires se définit par divers facteurs. Parmi ces derniers figurent entre-autres, le statut politique et le niveau de développement touristique atteint par ces territoires. Cette étude, en croisant diverses analyses a pour but d’évaluer et de comparer empiriquement à l’aide de vingt-cinq indicateurs socio-économiques et démographiques, l’influence de différentes variables et plus particulièrement de celle relative au statut politique sur la performance économique et sociale de deux groupes de territoires, l’un composé de seize petits espaces insulaires de la Caraïbe et du Pacifique, politiquement dépendants et l’autre, de dix-neuf îles des mêmes régions qui ont accédé à la souveraineté. D’une part, les résultats montrent que : comme variable explicative, le statut politique associé à d’autres facteurs intervient pour les deux-tiers dans la performance économique et sociale de ces îles. D’autre part, ils indiquent que les territoires insulaires politiquement dépendants sont économiquement plus prospères, socialement plus avancés, et démographiquement d’une plus grande maturité que ceux ayant acquis leur souveraineté. Toutefois, ces résultats ne doivent en aucun cas être interprétés comme des arguments contre la décolonisation, qui demeure une démarche moralement et universellement soutenable. Enfin, ils montrent également que les îles dépendantes qui bénéficient d’une large autonomie politique affichent en moyenne des résultats économiques et sociaux bien meilleurs que celles qui restent politiquement et centralement très liées à leur métropole, cas notamment de la Guadeloupe et de la Martinique pour lesquelles, en guise d’illustration nous proposons dans le cadre de leur probable évolution statutaire, un modèle de gouvernance qui, au plan politique soit le mieux adapté aux caractéristiques socio-économiques et

    Refractory status epilepticus carries a high risk of morbidity and mortality for children. Traditional treatment of status epilepticus consists of multiple anticonvulsant drugs and, if needed, induction of a medical coma. The ketogenic diet has been used for intractable epilepsy for many years. The purpose of this article is to report a case series of five patients with refractory status epilepticus successfully managed with the ketogenic diet. A summary of pediatric patients with refractory status epilepticus treated with diet was performed. Ketogenic diet therapy should be considered as a treatment option in pediatric patients with refractory status epilepticus. Copyright © 2014 Elsevier Inc. All rights reserved.

  15. PKIX Certificate Status in Hybrid MANETs

    Muñoz, Jose L.; Esparza, Oscar; Gañán, Carlos; Parra-Arnau, Javier

    Certificate status validation is a hard problem in general but it is particularly complex in Mobile Ad-hoc Networks (MANETs) because we require solutions to manage both the lack of fixed infrastructure inside the MANET and the possible absence of connectivity to trusted authorities when the certification validation has to be performed. In this sense, certificate acquisition is usually assumed as an initialization phase. However, certificate validation is a critical operation since the node needs to check the validity of certificates in real-time, that is, when a particular certificate is going to be used. In such MANET environments, it may happen that the node is placed in a part of the network that is disconnected from the source of status data at the moment the status checking is required. Proposals in the literature suggest the use of caching mechanisms so that the node itself or a neighbour node has some status checking material (typically on-line status responses or lists of revoked certificates). However, to the best of our knowledge the only criterion to evaluate the cached (obsolete) material is the time. In this paper, we analyse how to deploy a certificate status checking PKI service for hybrid MANET and we propose a new criterion based on risk to evaluate cached status data that is much more appropriate and absolute than time because it takes into account the revocation process.

    We describe a boy (aged 2 years and 7 months) with hemimegalencephaly who developed myoclonic status, which improved dramatically after total callosotomy. The patient experienced seizures beginning at age 2 days, at which time electroencephalography revealed a right unilateral burst suppression pattern, and cranial magnetic resonance imaging revealed an enlarged right hemisphere. At age 8 months, habitual seizures increased to more than daily frequency. At the same time, myoclonic status epilepticus appeared with frequent erratic, partial, massive myoclonic seizures and clouding of consciousness. These signs were accompanied by diffuse spike and spike-wave patterns on electroencephalography, indicating myoclonic status in nonprogressive encephalopathy. Total callosotomy performed at age 10 months resulted in the complete disappearance of myoclonic status and prominent decrease in habitual seizures. This description of hemimegalencephaly is the first, to our knowledge, in which total callosotomy alleviated myoclonic status epilepticus. Although the mechanism of myoclonic status epilepticus remains unknown, our results suggest that cortico-cortical pathways are involved in this type of myoclonic status.

In Moslem Baduy, only age and income are related to the nutritional status of children. In Moslem Baduy and the Outer Baduy, the correlation between age and W/A or W/H is similar: namely, the higher the age, the lower would the Z-score for the W/A or W/H. The income is significantly correlated to the child nutritional status according to Z-score for W/A with a high correlation coefficient, that is, 0.61. This means that the higher the income, the higher would be the Z-score value for the W/A.  The distribution of adults according to BMI classification in Outer Baduy it shows that 12.7% husbands and 17.6% wives are thin (wasted, while the

    2009-11-01

    The Large Hadron Collider has had a trying start-up and a challenging operational future lays ahead. Critical to the machine's performance is controlling a beam of particles whose stored energy is equivalent to 80 kg of TNT. Unavoidable beam losses result in energy deposition throughout the machine and without adequate protection this power would result in quenching of the superconducting magnets. A brief overview of the machine layout and principles of operation will be reviewed including a summary of the September 2008 accident. The current status of the LHC, startup schedule and upgrade options to achieve the target luminosity will be presented.

    The Pacific Northwest Laboratory has studied the safety aspects of monitoring the preoperational status of safety systems in nuclear power plants. The goals of the study were to assess for the NRC the effectiveness of current monitoring systems and procedures, to develop near-term guidelines for reducing human errors associated with monitoring safety system status, and to recommend a regulatory position on this issue. A review of safety system status monitoring practices indicated that current systems and procedures do not adequately aid control room operators in monitoring safety system status. This is true even of some systems and procedures installed to meet existing regulatory guidelines (Regulatory Guide 1.47). In consequence, this report suggests acceptance criteria for meeting the functional requirements of an adequate system for monitoring safety system status. Also suggested are near-term guidelines that could reduce the likelihood of human errors in specific, high-priority status monitoring tasks. It is recommended that (1) Regulatory Guide 1.47 be revised to address these acceptance criteria, and (2) the revised Regulatory Guide 1.47 be applied to all plants, including those built since the issuance of the original Regulatory Guide.

    Nowadays, IT departments provide, and people use, computing services of an increasingly heterogeneous nature. There is thus a growing need for a status display that groups these different services and reports their status and availability in a uniform way. The Service Level Status (SLS) system addresses these needs by providing a web-based display that dynamically shows availability, basic information and statistics about various IT services, as well as the dependencies between them. This paper first introduces the requirements SLS had to meet, and the main concepts behind it, like service availability and status, Key Performance Indicators (KPIs), sub/meta-services, and service dependencies. It then describes the SLS system architecture, and some interesting implementation details, such as the usage of XML Schemas. Since clear visualization of service availability and status is one of the main goals of SLS, emphasis is put on describing the intuitive web-based user interface.

    Evidence suggests that the effect of fasting on performance is not uniform, but it is dependent on the basal nutritional status of the subject. Breakfast consumption has a short-term effect in improving selected learning skills, especially work memory. School breakfast programmes have a positive effect on the nutritional status of children, on school attendance and probably on dropout rates. The effect of breakfast consumption on school performance depends on the interaction between the programme, student characteristics (malnutrition) and school organisation. Unless the school setting guarantees a minimum quality standard, the benefits of breakfast consumption will not be evident in performance in complex areas like language or maths.

    Symptomatic patients with a brainstem cavernoma are treated surgically with increasing frequency. Generally, the patient's benefit from this difficult surgical intervention is quantified by the assessment of neurological symptoms. To document the beneficial effect of surgery in a larger patient population by assessing the postoperative quality of life (QoL). In a series of 71 surgically treated patients, a detailed neurological status was assessed by Patzold Rating and Karnofsky Performance Status Scale. Patients rated their QoL with the Short Form 36 Health Survey. To document the effect of surgery on QoL, we devised a supplementary questionnaire. The last 24 patients completed Short Form 36 Health Survey pre- and postoperatively. Karnofsky Performance Status Scale improved in 44 of 71 surgical patients (62%), remained unchanged in 19 (27%), and deteriorated in 8 (11%) individuals. Patzold Rating showed a more detailed picture of the neurological symptoms. It correlated significantly with Karnofsky Performance Status Scale, which underscores its usefulness for patients with brainstem lesions. In the Short Form 36 Health Survey score, the Mental Component Summary improved with surgery (paired test, P = .015). In addition, 58 individuals (82%) declared a clear subjective benefit of surgery. The results of this large series support the notion that microsurgical removal of a brainstem cavernoma represents an effective therapy in experienced hands and is generally associated with good clinical outcome, both neurologically and in terms of QoL.

    The paper describes the status of repository development for the different waste categories. Low and Intermediate Waste Disposal facility of El Cabril was commissioned in 1992 and is in normal operation. The major modifications and activities during the last years are the adaptation to waste streams not initially foreseen such as some decommissioning waste or waste from steel industry, and the improvement of its performance assessment, supported by a R and D and refined models. As part of this facility, a new disposal facility specifically intended for very low activity waste has been constructed and commissioned in July 2008. Its design is based on the European Directive for hazardous waste disposal. National policy for Nuclear Spent Fuel and High-Level waste is focused on the development of a centralized storage facility of the vault type, whose site location would be selected through a volunteering process. Meanwhile, with the aim of solving specific problems, three individual storage facilities are in different status at reactor sites. Research on final solution, including some repository aspects as well as separation and transmutation are being carried out in accordance to ENRESA's R and D program. ENRESA has developed conceptual designs for non site specific repositories, both in granite and clay, and has carried out their corresponding performance assessment exercises. (authors)

    Full Text Available The objective of this study was to compare the periodontal status in postmenopausal women with osteopenia and osteoporosis. Material and Methods: We examined 43 postmenopausal women aged from 55 to 74 years. Material assessment of bones in every patient was performed by means of dual energy X-ray absorptiometry (DXA from two points on the skeleton – part of the femur neck and between the first and fourth lumbar vertebrae. A lipid blood test was done for patients of both groups. All patients were divided into two groups (the 1st with osteopenia, and the 2nd with osteoporosis. All patients were subjected to an oral clinical examination: the periodontal examination was composed of Plaque Index (PI, Pocket Score (PS, and Papillary Bleeding Index (PBI. X-ray analysis was performed for every patient. Results: The results of the clinical periodontal examination demonstrated that the mean PBI in patients in the 1st group had no significant differences from the PBI in patients in the 2nd group. PI value and PS findings in patients with general osteoporosis also had no statistical differences from the same parameters in patients with osteopenia. Conclusion: Under the circumstances of these patients’ characteristics and within the limits of the present study, we concluded that there is no significant difference in the periodontal status of postmenopausal women with systemic osteopenia and with osteoporosis.

    Full Text Available Refractory status epilepticus is a potentially life-threatening medical emergency. It requires early diagnosis and treatment. There is a lack of consensus upon its semantic definition of whether it is status epilepticus that continues despite treatment with benzodiazepine and one antiepileptic medication (AED, i.e., Lorazepam + phenytoin. Others regard refractory status epilepticus as failure of benzodiazepine and 2 antiepileptic medications, i.e., Lorazepam + phenytoin + phenobarb. Up to 30% patients in SE fail to respond to two antiepileptic drugs (AEDs and 15% continue to have seizure activity despite use of three drugs. Mechanisms that have made the treatment even more challenging are GABA-R that is internalized during status epilepticus and upregulation of multidrug transporter proteins. All patients of refractory status epilepticus require continuous EEG monitoring. There are three main agents used in the treatment of RSE. These include pentobarbital or thiopental, midazolam and propofol. RSE was shown to result in mortality in 35% cases, 39.13% of patients were left with severe neurological deficits, while another 13% had mild neurological deficits.

    After practical changes were approved to the initial conceptual design of the cryogenic system for MSU FRIB and an agreement was made with JLab in 2012 to lead the design effort of the cryogenic plant, many activities are in place leading toward a cool-down of the linacs prior to 2018. This is mostly due to using similar equipment used at CHLII for the 12 GeV upgrade at JLab and an aggressive schedule maintained by the MSU Conventional Facilities department. Reported here is an updated status of the cryogenic plant, including the equipment procurement status, plant layout, facility equipment and project schedule.

    Full Text Available Social hierarchy is a fact of life for many animals. Navigating social hierarchy requires understanding one's own status relative to others and behaving accordingly, while achieving higher status may call upon cunning and strategic thinking. The neural mechanisms mediating social status have become increasingly well understood in invertebrates and model organisms like fish and mice but until recently have remained more opaque in humans and other primates. In a new study in this issue, Noonan and colleagues explore the neural correlates of social rank in macaques. Using both structural and functional brain imaging, they found neural changes associated with individual monkeys' social status, including alterations in the amygdala, hypothalamus, and brainstem--areas previously implicated in dominance-related behavior in other vertebrates. A separate but related network in the temporal and prefrontal cortex appears to mediate more cognitive aspects of strategic social behavior. These findings begin to delineate the neural circuits that enable us to navigate our own social worlds. A major remaining challenge is identifying how these networks contribute functionally to our social lives, which may open new avenues for developing innovative treatments for social disorders.

    Full Text Available Working memory is important for mental reasoning and learning processes. Several studies in adults and school-age children have shown performance improvement in cognitive tests after working memory training. Our aim was to examine not only immediate but also long-term effects of intensive working memory training on cognitive performance tests in children. Fourteen healthy male subjects between 10 and 16 years trained a visuospatial n-back task over 3 weeks (30 min daily, while 15 individuals of the same age range served as a passive control group. Significant differences in immediate (after 3 weeks of training and long-term effects (after 2-6 months in an auditory n-back task were observed compared to controls (2.5 fold immediate and 4.7 fold long-term increase in the training group compared to the controls. The improvement was more pronounced in subjects who improved their performance during the training. Other cognitive functions (matrices test and Stroop task did not change when comparing the training group to the control group. We conclude that visuospatial working memory training in children boosts performance in similar memory tasks such as the auditory n-back task. The sustained performance improvement several months after the training supports the effectiveness of the training.

    2015-05-01

    The Compressed Baryonic Matter (CBM) experiment at the Facility for Anti-Proton and Ion Research (FAIR) will explore the phase diagram of strongly interacting matter at highest net baryon densities and moderate temperatures. The CBM physics program will be started with beams delivered by the SIS 100 synchrotron, providing energies from 2 to 11 GeV/nucleon for heavy nuclei, up to 14 GeV/nucleon for light nuclei, and 29 GeV for protons. The highest net baryon densities will be explored with ion beams up to 45 GeV/nucleon energy delivered by SIS 300 in the next stage of FAIR. Collision rates up to 107 per second are required to produce very rare probes with unprecedented statistics in this energy range. Their signatures are complex. These conditions call for detector systems designed to meet the extreme requirements in terms of rate capability, momentum and spatial resolution, and a novel DAQ and trigger concept which is not limited by latency but by throughput. The article discusses the development status of the CBM sub-systems for charged particle tracking, vertex detection, electron/muon identification, hadron/time-of-flight measurement, electromagnetic and zero-degree calorimetry, in terms of prototypes and expected physics performance. The concept and development status of CBM's central detector, the Silicon Tracking System STS are presented in somewhat more detail.

    We review the status of FEL source activity of the ongoing SPARC FEL experiment, developed within the framework of a collaboration among ENEA, CNR, INFN, INFM, Sincrotrone Trieste and University of Rome Tor Vergata. The project is aimed at realizing a SASE-FEL source, operating in the visible (around 500 nm), with an extended range of tunability down to the VUV (100 nm) by the use of the mechanism of non-linear harmonic generation. The development of the relevant activities foresees the realization of an advanced 150 MeV photo-injector source, aimed at producing a high brightness electron beams, needed to drive a SASE-FEL experiment, and a 14 m long undulator. We present the status of the design and construction of SPARC FEL device. In particular we discuss the choice of the project parameters, their optimization and the sensitivity of the SPARC performance to any parameter variation. We will show, using start-to-end simulations, what is the impact of the e-beam and of the undulator parameters on the characteristics of the output laser field and in particular on the amount of the non-linearly generated power at higher harmonics.

    The report gives an account of the development of material and fabrication technology for copper canisters with cast inserts during the period from 2000 until the start of 2004. The engineering design of the canister and the choice of materials in the constituent components described in previous status reports have not been significantly changed. In the reference canister, the thickness of the copper shell is 50 mm. Fabrication of individual components with a thinner copper thickness is done for the purpose of gaining experience and evaluating fabrication and inspection methods for such canisters. As a part of the development of cast inserts, computer simulations of the casting processes and techniques used at the foundries have been performed for the purpose of optimizing the material properties. These properties have been evaluated by extensive tensile testing and metallographic inspection of test material taken from discs cut at different points along the length of the inserts. The testing results exhibit a relatively large spread. Low elongation values in certain tensile test specimens are due to the presence of poorly formed graphite, porosities, slag or other casting defects. It is concluded in the report that it will not be possible to avoid some presence of observed defects in castings of this size. In the deep repository, the inserts will be exposed to compressive loading and the observed defects are not critical for strength. An analysis of the strength of the inserts and formulation of relevant material requirements must be based on a statistical approach with probabilistic calculations. This work has been initiated and will be concluded during 2004. An initial verifying compression test of a canister in an isostatic press has indicated considerable overstrength in the structure. Seamless copper tubes are fabricated by means of three methods: extrusion, pierce and draw processing, and forging. It can be concluded that extrusion tests have revealed a

  6. Nuclear energy - status and outlook

    2007-07-01

    Rising expectations best characterize the current prospects of nuclear power in a world that is confronted with a burgeoning demand for energy, higher energy prices, energy supply security concerns and growing environmental pressures. It appears that the inherent economic and environmental benefits of the technology and its excellent performance record over the last twenty years are beginning to tilt the balance of political opinion and public acceptance in favour of nuclear power. Nuclear power is a cost-effective supply-side technology for mitigating climate change and can make a substantial contribution to climate protection. This paper reviews the current status of nuclear power and its fuel cycle and provides an outlook on where nuclear power may be headed in the short-to-medium run (20 to 40 years from now). (auth)

    The Facility for Rare Isotope Beams (FRIB) will provide a wide range of primary ion beams for nuclear physics research with rare isotope beams. The FRIB SRF linac will be capable of accelerating medium and heavy ion beams to energies beyond 200 MeV/u with a power of 400 kW on the fragmentation target. This paper presents the status of the FRIB Front End designed to produce uranium and other medium and heavy mass ion beams at world-record intensities. The paper describes the FRIB high performance superconducting ECR ion source, the beam transport designed to transport two-charge state ion beams and prepare them for the injection in to the SRF linac, and the design of a 4-vane 80.5 MHz RFQ. The paper also describes the integration of the front end with other accelerator and experimental systems.

    A 72-year-old woman presented with first onset of seizure with no prior history of cognitive dysfunction. EEG revealed focal non-convulsive status epilepticus. MRI brain showed a left temporal non-enhancing lesion. Temporal pole biopsy showed acute neuronal necrosis and astrocyte hyperplasia together with extensive amyloid plaques and neurofibrillary tangles. Perivascular oligodendroglial hyperplasia was present. Postmortem examination revealed extensive plaque and tangle disease. Perivascular oligodendroglial hyperplasia was limited to the left temporal area. The presence of focal perivascular oligodendroglial hyperplasia in the left temporal cortex, combined with extensive plaque and tangle disease may have contributed to the focal status epilepticus in this patient. Although the presence of focal perivascular oligodendroglial hyperplasia has been reported in cases of temporal lobe epilepsy, it has not been reported as a cause of seizure in patients with Alzheimer\\'s disease previously. Further studies for clinical-pathologic correlation would be required to confirm this hypothesis.

    2004-01-01

    In addition to its medical importance as parasitic pathogen, Entamoeba has aroused people's interest in its evolutionary status for a long time. Lacking mitochondrion and other intracellular organelles common to typical eukaryotes, Entamoeba and several other amitochondrial protozoans have been recognized as ancient pre-mitochondriate eukaryotes and named "archezoa", the most primitive extant eukaryotes. It was suggested that they might be living fossils that remained in a primitive stage of evolution before acquisition of organelles, lying close to the transition between prokaryotes and eukaryotes. However, recent studies revealed that Entamoeba contained an organelle, "crypton" or "mitosome", which was regarded as specialized or reductive mitochondrion. Relative molecular phylogenetic analyses also indicated the existence or the probable existence of mitochondrion in Entamoeba. Our phylogenetic analysis based on DNA topoisomerase II strongly suggested its divergence after some mitchondriate eukaryotes. Here, all these recent researches are reviewed and the evolutionary status of Entamoeba is discussed.

    This article presents and discusses findings on the health status of newcomers residing in Windsor, Ontario. The data are part of a larger study, which was based on the Ontario Health Survey's questionnaire. Data were collected from 548 newcomers through home visits, focus groups, mail surveys, and telephone interviews. Descriptive multivariate analyses focused on main areas in newcomers' physical and mental health status and their access to health services. The findings identified that most newcomers do not have acute, life-threatening physical problems or chronic illness. They do not experience major problems with access to health care or activity limitations. Men are happier, more satisfied with their health, and less stressed than women. This study has implications for adoption of sensitive transcultural approaches to promote newcomers' health. Special challenges lie in women's health and mental health.

    To determine if civil status acts as a risk factor in suicide and how it modifies according to gender, age and population size. A retrospective study which analyzes information from the mortality data from the National Institute of Statistics, Geography and Information, from 1998 to 2002. Variables like suicides age, sex, cause of death, federal entity, population size and civil status were registered. Single men showed twofold risk for committing suicide. Women did not show any associated risk for suicide according to civil status. The risk of married men for committing suicide increased gradually with age. Medium-sized communities with less than 19,999 habitants presented the highest risk for habitants to commit suicide. Suicide is associated to gender especially to men who are not married and living in small and medium-sized communities. One explanation could be the lack of integrated behavior as defined by Emile Durkheim, where the physical density of society will determine behavior and ideas. This social structure phenomenon is called the "moral cocoon." This works around the individual being less individualistic and granting him/her the feeling of belonging to a group.

    Modern military operations utilize complex technologies that require high levels of readiness and sustained cognitive and physical performance of combat military combat personnel. These military operations often depend on weapon systems that use advanced computer technology coupled with an array of sensors that provide continuous information on the battlefield environment and on equipment function. However there is a lack of real-time information on status of the personnel who control these systems and who are vital to mission success. Failure of the human element renders the weapon system useless so it is important to know if an individual is physically and cognitively fit to perform his or her task. Based on the premise that status of metabolic processes provide an early indication of a change in an individuals physiological status, monitoring of selective biomarkers of metabolism and organ function can provide insight on the individual"s ability to perform mission tasks. During combat individuals may not be aware that they have reached a compromised physiological condition due to dehydration, physical exertion, stress, fatigue, sleep deprivation, exposure to toxins or other condition that may affect physical and cognitive performance and health. Systems that can provide the individual or his or her commander with information about significant changes in one or more metabolic functions could permit timely intervention to correct the condition. In the event that serious injury has already occurred to an individual, metabolic monitoring can provide valuable intelligence needed for decisions on achieving mission objectives.

    2010-01-01

    Full Text Available Introduction. Convulsive status epilepticus is the most urgent neurological medical emergency in children. Generalized convulsive status epilepticus is the most common and life-threatening type of status epilepticus. It is not a syndrome in the same sense as febrile convulsions, benign rolandic epilepsy, and infantile polymorphic epilepsy. These latter disorders have a tight age frame, seizure semiology, and a reasonably predictable outcome. Episodes of convulsive status epilepticus can occur in each: occasionally in symptomatic and febrile convulsions, and Lennox Gastaut syndrome, rarely in benign rolandic epilepsy, and West syndrome. Etiology of convulsive status epilepticus. Status epilepticus has many causes, which vary depending on the age and patient population. Convulsive status epileptucus continues to be associated with significant neurological morbidity and mortality, with different hazards and outcome. Although the outcome is dependent on etiology, it is known that appropriate early management may reduce mortality and some of the morbidity associated with convulsive status epilepticus. Discussion. Status epilepticus is a disorder in which the mechanisms attempting at terminating the seizure fail. Continued convulsive activity in convulsive status epilepticus results in decompensation of all organs and systems, thus being life threatening. Seizure activity in convulsive status epilepticus is associated with neuronal damage. The aim should be to halt this activity urgently, using, ideally, a 100% effective drug, administered quickly, without compromising the consciousness level or producing other negative effects on cardiovascular, respiratory function or other unexpected effects.

    Scleromyxedema is a rare dermatologic disorder, characterized by erythematous or yelowish lichenoid waxy papules. Neurological manifestations are rare but wel-recognized. A 51-year-old woman, diagnosed with scleromyxedema, was admitted to the hospital with status epilepticus, caused by brain lesions, as disclosed in a brain magnetic resonance imaging (MRI). The patient was treated with anticonvulsants and corticosteroids and gradualy recovered fuly. A complete remission of the lesions was shown in a folow-up brain MRI. In cases with scleromyxedema and the presence of neurological manifestations, we need to pay attention to central nervous system involvement, especialy when combined with brain MRI lesions, and treat the patient appropriately.

    Heat stress is known to impair performance and to induce oxidative stress in poultry. The aim of the present study was to compare the effects of dietary supplementation of dl-methionine (dl-M) or the synthetic analog 2-hydroxy-4-methylthiobutanoic acid (dl-HMTBA) on broiler growth performance, plasma hormone levels, and some oxidative stress-related parameters under conditions of chronic exposure to high temperatures (HT). From 2 to 6 wk of age, male broiler chickens were reared under either a constant temperature of 32°C until 6 wk of age or a normal temperature scheme (gradual decrease to 18°C at 5 wk of age). Chicks in both the normal and HT treatments were provided with a commercial grower diet supplemented with either 1.0 or 1.2 g/kg of dl-M or 1.0 or 1.2 g/kg of dl-HMTBA. Because there were no effects of supplement dose, data were pooled over both doses within each temperature treatment. The chronic HT treatment impaired feed intake and BW gain, but these negative effects were less pronounced when the chickens received dl-HMTBA. Exposure to HT was also associated with decreased (P chickens subjected to HT were characterized by significantly lower plasma TBA-reactive substance levels. In contrast, at 6 wk of age, plasma TBA-reactive substance levels were significantly increased by HT, but this effect was observed only for the chickens receiving dl-M and not for those receiving dl-HMTBA. High temperatures induced a significant increase in hepatic total glutathione (GSH) and oxidized GSH levels, regardless of the supplemental source. However, the hepatic ratios of reduced GSH to total GSH and reduced GSH to oxidized GSH were highest in chickens supplemented with dl-HMTBA. In conclusion, dl-HMTBA supplementation partially prevented the growth-depressing effects of chronic heat exposure compared with dl-M supplementation. It can be inferred that dl-HMTBA is more efficient in alleviating HT-induced oxidative damage because of a more favorable reduced GSH

    Reliable identification of Mycobacterium tuberculosis infection or tuberculosis (TB) disease in young children is vital to assure adequate preventive and curative treatment. The tuberculin skin test (TST) and IFNγ-release assays may supplement the diagnosis of pediatric TB as cases are typically bacteriologically unconfirmed. However, it is unclear to what extent the performance of TST and QuantiFERON-TB Gold In-Tube (QFT; Cellestis' IFNγ-release assay test) depends on the demographic, clinical and nutritional characteristics of children in whom they are tested. During a 2-year prospective observational study of 4382 neonates in Southern India, children with suspected TB were investigated and classified by a standard TB diagnostic algorithm. Clinical TB was diagnosed in 13 of 705 children referred for case verification with suspected TB. TST and QFT had a susceptibility for clinical TB of 31% and 23%, respectively, in this group. Children tuberculosis infection and more prone to indeterminate QFT results. TST was less reliable in children with wasting.

    Full Text Available To raise the power of genome-wide association studies (GWAS and avoid false-positive results in structured populations, one can rely on mixed model based tests. When large samples are used, and when multiple traits are to be studied in the ’omics’ context, this approach becomes computationally challenging. Here we consider the problem of mixed-model based GWAS for arbitrary number of traits, and demonstrate that for the analysis of single-trait and multiple-trait scenarios different computational algorithms are optimal. We implement these optimal algorithms in a high-performance computing framework that uses state-of-the-art linear algebra kernels, incorporates optimizations, and avoids redundant computations, increasing throughput while reducing memory usage and energy consumption. We show that, compared to existing libraries, our algorithms and software achieve considerable speed-ups. The OmicABEL software described in this manuscript is available under the GNU GPL v. 3 license as part of the GenABEL project for statistical genomics at http: //www.genabel.org/packages/OmicABEL.

  1. Iron status and the female athlete.

    2012-06-01

    Iron deficiency (ID) is the most prevalent micronutrient deficiency disorder in the world. In the developed world, the greatest prevalence of ID and iron deficiency anemia (IDA) occurs in premenopausal women. Premenopausal women experience ID and IDA due to inadequate consumption of dietary iron coupled with iron losses through physiologic processes such as menstruation. Further, female athletes may experience an elevated risk of ID and IDA, as hepcidin, a peptide hormone that inhibits iron absorption and sequesters iron in the macrophage, may rise in response to physical activity. Declines in physical and cognitive performance have been demonstrated in female athletes with ID and IDA. Performance decrements are attenuated as iron status improves. This review will focus on iron status in female athletes, and will include a review of nutritional countermeasures to prevent ID and IDA.

    Historically, physicians completed status assignment during the admission process. Incorrect status assignment of patients can result in reimbursement problems and denial of payment by Medicare, Medicaid, and private insurance companies. The purpose of this study was to evaluate the impact of case manager's role with status assignment during the admission process by looking at the denial of payment for services rendered. Denial rates were evaluated for two 15-month time periods: preintervention group (status assignment completed by physicians) and intervention group (status assignment recommended by case managers with physician signature). Denial data for all diagnosis-related groups possessing a more than 2% denial rate related to status assignment were further examined to identify the rationale for denial of payment. FINDINGS/OUTCOMES: The greatest denial rates for payment occurred during the Preintervention Period, when physicians assigned status for patients independently. There was a significant reduction in denial of payment for most diagnosis-related groups during the Intervention time period when case managers were recommending status assignment. Evaluation of denial data provides an opportunity to target creative performance improvement solutions to reduce denial of payment related to incorrect status assignment.

  3. Wage differences according to health status in France.

    Many OECD countries have implemented anti-discrimination laws in recent decades. However, according to the annual report published in 2010 by the French High Authority for the Fight against Discrimination and for Equality, the second most commonly cited factor in discrimination claims since 2005 is a handicap or health status. The aim of this research is to estimate the level of unexplained components in the wage gap that can be attributed to wage discrimination based on health status in France in 2010 utilizing data from the Health, Healthcare and Insurance survey among 1594 individuals. Three health indicators are used: self-perceived health status, activity limitations and long-term chronic illness. To measure the wage gap according to an individual's health status, the analysis considers the endogenous selection of health status and unobserved differences in productivity. The results demonstrate that wage discrimination is experienced by individuals in poor health regardless of the health indicator utilized. The hourly wage rate among individuals with poor self-assessed health status is on average 14.2% lower than among individuals with good self-assessed health status. However, for individuals suffering from a long-term chronic illness or an activity limitation, the gap is 6.3% and 4.5%, respectively. The decomposition performed on wage differences according to health status by correcting for health status selection bias and controlling for unobserved differences in productivity indicates that the 'unexplained component' that can be attributed to wage discrimination is equal to 50%.

    There is interest in age-related cognitive decline and environmental risk factors for Alzheimer's disease (AD). This interest is focused on individual differences in exposure to agents that may harm or protect cognitive function. Caffeine is used as a short acting mental stimulant and may possess longer-term properties that protect against age-related decline and, possibly, AD. The current study aimed to: 1) examine current cognitive function in a narrow age range sample (n=351) without dementia (MMSE>25) who are, by reason of age, entering the period of increased risk of AD; and 2) link cognitive function to self-reported intake of caffeine and socioeconomic status (SES). Possible confounding by gender, childhood intelligence, education, and symptoms of anxiety and depression was introduced into the statistical model. There were significant differences between SES groups in caffeine intake (pcognitive performance (pcaffeine intake were associated with slower digit symbol speed (F =3.38, pcaffeine during cognitive testing and strong links between SES and cognitive performance. No evidence in support of cognitive enhancing effects of caffeine was found.

    虽然近年我国出现了很多政府绩效评估的典型例子,但是由于政府体制、公民参与意识和公民素质不高以及政府和公民所掌握信息的不对称等一系列问题,我国政府绩效评估还停留在有限参与阶段。解决政府绩效评估存在的问题,不仅需要相应地加快政治体制改革的步伐,积极构建服务型政府,而且需要培育公民的政治主体意识及参与意识,以保持评估信息传输渠道的畅通。%In spite of some typical examples appearing in recent years, the evaluation on government's performance in our country is still at the level of limited participation, due to a series of problems such as government mechanism, citizens' participation consciousness, citizen's poor qualities, and asymmetry between the information held by gov- ernments and citizens. To solve the problems in the evaluation, we should quicken the reform of political system, es- tablish service- oriented governments, and cultivate citizens' participation consciousness as political subjects, so as to keep smooth transmission channels for evaluation information.

    Colostrum may have the ability to improve the diagnostic accuracy of some tests when compared to serum for important livestock diseases because of the high concentrations of immunoglobulins present within this sample type. The ELISA for Johne's disease is one such test, as it suffers from low sensitivity when testing serum samples collected during the subclinical stage of infection. Blood and colostrum samples were collected from 34 Jersey dairy cows and tested for antibodies against Mycobacterium avium subspecies paratuberculosis (MAP) by ELISA. Fecal samples were also collected and tested by a high-throughput Johne's polymerase chain reaction (HT-J PCR) assay and fecal culture (FC), with the latter being used as the reference test. A receiver operating characteristic (ROC) analysis was performed, and the area under the curve (AUC) was calculated. The HT-J PCR and FC results were also compared. Of the 34 cows in this study, 4 had FC results consistent with MAP infection. The HT-J PCR did not identify any FC-positive cows. Using a 1:20 dilution and sample-to-positive (S/P) ratio cutoff threshold of 0.15, the relative sensitivity values of both serum (AUC 0. 56) and colostrum (AUC 0.63) were 0%. With lower sample dilutions, the relative sensitivity values of serum were 0% (1:2, AUC 0.62; 1:5, AUC 0.55); however, the relative sensitivity value of colostrum was 75% (95% confidence interval [CI]: 19-99%) at a dilution of 1:5, S/P ratio cutoff threshold of 0.15, and AUC of 0.73 (95% CI: 0.55-0.87). The testing of colostrum samples for MAP-specific antibodies by ELISA may provide improved identification of animals in the early stages of infection with MAP when compared with serum samples.

  9. Age, relationship status, and the planning status of births

    Full Text Available In the United States historically, births to older mothers have been more likely to be planned than births to younger mothers, and births to unmarried women have been less likely to be planned than births to married women. As the average age of mothers has increased and more births have occurred outside of marriage in the United States, the intersection of these trends may have weakened the traditional linkage between age and birth planning status. In this article, we examine differences by maternal age in planning status of births using The 2002 National Survey of Family Growth. We find that age is strongly associated with planning status, but the association is reduced in magnitude when controlling for relationship status and is stronger for first and second births than for higher-parity births. Further, the association between union status and the planning status of births varies by race-ethnicity.

    During the Golden Age of Medicine (20th Century), scientific and technological breakthroughs enabled physicians to treat diseases that were previously incurable. The idealist, romantic approach of medical practice believed in the right of every human being to receive the best treatment possible, regardless of cost. However, the rise in health care expenditure at the end of the last century made this approach impossible to follow. The growing health expenses are due to the increased percentage of chronically sick patients and elderly population, costs of novel technologies and public expectations. Israel spends 7.9% of its GDP on health, a figure which has not changed in the last fifteen years, while other western countries spend a considerably higher and increasing percentage of their GDP on health. Public resources must be allocated in order to maintain the health of the population and to decrease inequities. A data-based demonstration of the population health status and health care system is therefore mandated. in this issue of the Harefuah, three articles are presented which try to show different aspects of the measurement of Israeli heath status. The data accumulated is used to improve the health status of the Israeli people. The Israel Medical Association (IMA) has assumed responsibility for the creation of an objective index for the measurement and evaluation of the public state of health and the healthcare system. The goal of the IMA National Health Index is to promote discussions regarding medicine and health in Israel, and to serve as a tool to be used by relevant policy makers. Prof. Israeli et al discuss the merits of the National Health Index as well as delineate the difficulties regarding the methodology and choice of parameters. They suggest methods for its improvement. Dr Cohen and his colleagues of Clalit Health Services present the Quality Health indicator program in the community. In effect over the past fifteen years, this program is based on

    TAROT-1 is an automatic, autonomous ground based observatory whose primary goal is the rapid detection of the optical counterparts of cosmic gamma-ray burst sources. It will be able to begin imaging any GRB localization 8 seconds after receipt of an alert from CGRO/BATSE or HETE-2. TAROT-1 will reach the 17th V magnitude in 10 seconds, at a 10$\\sigma$ confidence level. TAROT will be able to observe GRB positions given by Beppo-SAX or RXTE, EUV transients from ALEXIS alerts, etc. TAROT will also study a wide range of secondary objectives and will feature a complete automatic data analysis system, and a powerful scheduling software. TAROT will be installed this fall on the Plateau du Calern, 1200m above sea level. We report on the status of the project.

    The status of French reactors is reviewed. The ORPHEE and RHF reactors can not be operated with a LEU fuel which would be limited to 4.8 g U/cm{sup 3}. The OSIRIS reactor has already been converted to LEU. It will use U{sub 3}Si{sub 2} as soon as its present stock of UO{sub 2} fuel is used up, at the end of 1994. The decision to close down the SILOE reactor in the near future is not propitious for the start of a conversion process. The REX 2000 reactor, which is expected to be commissioned in 2005, will use LEU (except if the fast neutrons core option is selected). Concerning the end of the HEU fuel cycle, the best option is reprocessing followed by conversion of the reprocessed uranium to LEU.

    Installation of Advanced LIGO, a second-generation interferometric gravitational wave observatory, began in earnest in October of 2010. Initial LIGO instrumentation was de-installed, vacuum chambers and envelope modified, and the installation of scientific payloads begun. At LIGO Hanford Observatory, optics and suspensions comprising one of two 4km Fabry-Perot arms have been deployed and commissioned, resonating green light in an experiment to test and understand the process of controlling cavity lengths (``lock acquisition''). At LIGO Livingston, cornerstation optic and seismic isolation installation has matured such that the primary infrared laser and a suspended mode cleaner cavity (employed to spacially clean the interferometer input beam) are locked and under commissioning test. In this talk we present the status of Advanced LIGO installation and integration, and sketch the promising future of gravitational wave observation and astronomy.

  17. Biomarkers of Selenium Status

    Full Text Available The essential trace element, selenium (Se, has multiple biological activities, which depend on the level of Se intake. Relatively low Se intakes determine the expression of selenoenzymes in which it serves as an essential constituent. Higher intakes have been shown to have anti-tumorigenic potential; and very high Se intakes can produce adverse effects. This hierarchy of biological activities calls for biomarkers informative at different levels of Se exposure. Some Se-biomarkers, such as the selenoproteins and particularly GPX3 and SEPP1, provide information about function directly and are of value in identifying nutritional Se deficiency and tracking responses of deficient individuals to Se-treatment. They are useful under conditions of Se intake within the range of regulated selenoprotein expression, e.g., for humans <55 μg/day and for animals <20 μg/kg diet. Other Se-biomarkers provide information indirectly through inferences based on Se levels of foods, tissues, urine or feces. They can indicate the likelihood of deficiency or adverse effects, but they do not provide direct evidence of either condition. Their value is in providing information about Se status over a wide range of Se intake, particularly from food forms. There is need for additional Se biomarkers particularly for assessing Se status in non-deficient individuals for whom the prospects of cancer risk reduction and adverse effects risk are the primary health considerations. This would include determining whether supranutritional intakes of Se may be required for maximal selenoprotein expression in immune surveillance cells. It would also include developing methods to determine low molecular weight Se-metabolites, i.e., selenoamino acids and methylated Se-metabolites, which to date have not been detectable in biological specimens. Recent analytical advances using tandem liquid chromatography-mass spectrometry suggest prospects for detecting these metabolites.

    There are known racial disparities in renal graft survival. Data are lacking comparing associations of race/ethnicity and socioeconomic status with graft failure and functional status after transplantation. Our goal was to test if African-American and Hispanic race/ethnicity and poverty are associated with worse outcomes following renal transplantation. We performed a retrospective cohort study using a nationwide registry (United Network for Organ Sharing). We studied 4,471 adults who received renal transplants in 1990. Outcomes were graft failure and functional status over 10 years. Cumulative incidence of graft failure was higher among African-Americans and Hispanics than whites (77% vs. 64% vs. 60 %; Ppoverty status was not (RR 1.0, 95% CI 0.9-1.1). Days with impaired functional status were higher for African-Americans compared to whites (RR 1.6, 95% CI 1.3-1.9) but not independent of poverty. Poverty was independently associated with impaired functional status (RR 1.3, 95% CI 1.0-1.6). African-Americans and Hispanics had higher rates of graft failure compared to whites after adjustment for poverty and other covariates whereas poverty, but not race/ethnicity, was related to functional status following renal transplantation. National datasets should include individual-level measures of socioeconomic status in order to improve evaluation of social and environmental causes of disparities in renal transplant outcomes.

  20. High & mighty: Implicit associations between space and social status

    Full Text Available Figurative language, the built environment, and our perceptuo-motor experiences frequently associate social status with physical space. Linguistic references such as high status or climbing the corporate ladder, and built places such as the U.S. Capitol building link social and physical hierarchies. In three experiments we examine the source and extent of these associations by testing whether people implicitly associate abstract social status indicators with concrete representations of spatial topography (level versus mountainous land and relatively abstract representations of cardinal direction (south and north. Experiment 1 demonstrates speeded performance during an Implicit Association Test (IAT; Greenwald et al., 1998 when average social status is paired with level topography and high status with mountainous topography. Experiments 2 and 3 demonstrate a similar effect but with relatively abstract representations of cardinal direction (south and north, with speeded performance when average and powerful social status are paired with south and north coordinate space, respectively. Abstract concepts of social status are perceived and understood in an inherently spatial world, resulting in powerful associations between abstract social concepts and concrete and abstract notions of physical axes. These associations may prove influential in guiding daily judgments and actions.
