Respiratory and locomotor muscle blood-volume and oxygenation kinetics during intense intermittent exercise

Abstract In this study, we examined the time course of changes in the blood volume and oxygenation of accessory respiratory (RM) and locomotor (LM) muscles, and the interrelationships of changes in these parameters during maximal incremental intermittent exercise in 15 non-endurance-trained active men. Blood volume and oxygenation of the serratus anterior and of vastus lateralis were measured simultaneously by near-infrared spectroscopy. The respiratory compensation point, and the breakpoints where abrupt changes were apparent in RM and LM blood volume and oxygenation versus time were identified. During exercise, the decreases in RM and LM oxygenation were accentuated in the vicinity of the respiratory compensation point. This was concomitant with a reduction in LM, but not RM, blood volume. The time at which the respiratory compensation point and the breakpoints in RM and LM blood volume and oxygenation were detected (70.2–75.0% exercise time) did not differ, and were inter-correlated (r=0.56 to 0.95). Moreover, the rate of the accelerated fall of oxygenation in the locomotor muscles was correlated with that of the decline in blood volume in that area (r=0.73), and with that of the accelerated fall of oxygenation in the respiratory muscles (r=0.71). The results suggest that the high ventilatory demand, which occurs naturally during intense intermittent exercise in non-endurance-trained individuals, may precipitate an accelerated fall in RM oxygenation, concomitant with a reduction in LM blood volume and an accentuated decline in LM oxygenation. Such responses are likely to occur above the respiratory compensation point during intermittent exercise.
Overview of the TREC 2011 Chemical IR Track

Abstract : TREC 2009 was the first year of the Chemical IR Track, which focuses on evaluation of search techniques for discovery of digitally stored information on chemical patents and academic journal articles. The track included two tasks: Prior Art (PA) and Technical Survey (TS) tasks. This paper describes how we designed the two tasks and presents the official results of eight participating groups.
Fractal Characterization of Web Workloads

Understanding the workload of Web and e-commerce sites is a fundamental step in sizing the IT infrastructure that supports these sites and in planning for their evolution so that Quality of Service (QoS) goals are met within cost constraints. This paper discusses the use of fractal-based methods to simplify and characterize Web and e-commerce workloads. Fractal clustering is quite appropriate to find sets of points that are somehow “similar” with respect to a fractal dimension. This implies that clusters do not have to be shaped as hyperspheres, as is the case with traditional clustering techniques. We apply the fractal techniques to an actual e-commerce workload and use the results to understand what customers do, what navigational patterns they follow, and to identify groups of users that have similar behavior. A comparison with results obtained with k-means analysis is also discussed. The main contributions of this work are techniques that improve the process of workload characterization.
Quick Test Validation: Scores of Adults in a Welfare Setting

The Full Scale Wechsler Adult Intelligence Scale (WAIS) and Quick Test (QT) Form 1 were administered to 45 Ss; their ages ranged from 16 to 56 yr. (Mago = 17.81 yr.). The Full Scale WAIS MIQ was 68.24 (SD = 21.55) and the MIQ on Form 1 of the QT was 58.84 (SD = 22.14), which became 73.84 when corrected. QT IQs and raw scores yielded substantive and significant (p = .001) correlations with all WAIS raw and scaled scores.
Serum S-100 and neuron-specific enolase for prediction of regaining consciousness after global cerebral ischemia.

BACKGROUND AND PURPOSE The aim of our study was to assess the use of S-100 protein (S-100) and neuron-specific enolase (NSE) in serum and cerebrospinal fluid (CSF) for the prediction of patients' regaining consciousness after acute global cerebral ischemia. METHODS Sixty-four unconscious patients were followed until the return of consciousness or until death/vegetative state. Serum and CSF samples for measurement of S-100 and NSE using an immunoradiometric assay technique were obtained 24 hours (serum) and 48 hours (CSF) after the acute event and correlated with patient outcome. RESULTS Values for serum S-100 protein, serum NSE, CSF S-100, and CSF NSE were significantly different in the 2 outcome groups. A serum S-100 value of >0.7 micrograms/L was found to be a predictor of not regaining consciousness, with a high positive predictive value (95%) and high specificity (96%). CONCLUSIONS S-100 protein used as serum marker 24 hours after acute global cerebral ischemia gives reliable and independent information on the outcome of the patient that is comparable or superior to that obtained with CSF markers. Therefore, S-100 may be a serum marker of brain cell damage useful for clinical assessment of these patients.
Linked networks for learning and expressing location-specific threat

Significance When exploring our world, we must learn about the identity and location of threats. Despite the adaptive significance of these processes, little is known about the component processes, which allow human learning. We delineate these processes engaged as people learn associations between spatial location and its aversive value in a virtual environment. Ventromedial prefrontal cortex (vmPFC), anterior hippocampus, and amygdala form a network that supports such learning. Dorsal anterior cingulate (dACC) and insula engagement reflects the cognitive and visceral appraisal of looming danger. Encounters with imminent threats recruit the periaqueductal grey with the initiation of defensive behavior. Findings highlight how networks of distributed brain structures interact to support distinct processes engaged during learning, each of which may malfunction to give risk to features of psychological disorders. Learning locations of danger within our environment is a vital adaptive ability whose neural bases are only partially understood. We examined fMRI brain activity while participants navigated a virtual environment in which flowers appeared and were “picked. ” Picking flowers in the danger zone (one-half of the environment) predicted an electric shock to the wrist (or “bee sting”); flowers in the safe zone never predicted shock; and household objects served as controls for neutral spatial memory. Participants demonstrated learning with shock expectancy ratings and skin conductance increases for flowers in the danger zone. Patterns of brain activity shifted between overlapping networks during different task stages. Learning about environmental threats, during flower approach in either zone, engaged the anterior hippocampus, amygdala, and ventromedial prefrontal cortex (vmPFC), with vmPFC–hippocampal functional connectivity increasing with experience. Threat appraisal, during approach in the danger zone, engaged the insula and dorsal anterior cingulate (dACC), with insula–hippocampal functional connectivity. During imminent threat, after picking a flower, this pattern was supplemented by activity in periaqueductal gray (PAG), insula–dACC coupling, and posterior hippocampal activity that increased with experience. We interpret these patterns in terms of multiple representations of spatial context (anterior hippocampus); specific locations (posterior hippocampus); stimuli (amygdala); value (vmPFC); threat, both visceral (insula) and cognitive (dACC); and defensive behaviors (PAG), interacting in different combinations to perform the functions required at each task stage. Our findings illuminate how we learn about location-specific threats and suggest how they might break down into overgeneralization or hypervigilance in anxiety disorders.
Genetic and epigenetic alterations affecting PARK-2 expression in cervical neoplasm among North Indian patients

The recent investigation on PARK-2, a putative tumor suppressor gene, has found that it has been altered in multiple human malignancies. However, the clinical impact of PARK-2 alteration in uterine cervix carcinoma has not yet been studied. Therefore, we aimed to examine mutations, promoter hypermethylation, and protein expression of PARK-2 among the North Indian patients and their association with clinical parameters to evaluate the implication of PARK-2 in the genesis of cervical cancer. A total of 168 patient samples were processed for mutational analysis by single-strand conformation polymorphism, sequencing, and further in silico analysis of the identified mutations. Promoter hypermethylation by methylation-specific polymerase chain reaction and expression of PARK-2 were performed using immunohistochemistry. Statistical correlation between molecular findings and the clinicopathological parameters was taken to figure out the meaningful outcome. As per our findings, 3.5% (6/168) tumors showed novel missense mutations in exon 11 of PARK-2. In silico analysis showed high structural deviations manifested by mutations, A398D and Y391N, in both mutant proteins as compared to wild type. Promoter hypermethylation was observed in total of 29% of (48/168) tumor samples. Furthermore, 46.43% tumors (78/168) exhibited loss of PARK-2 expression in cervical carcinoma. The loss of expression of PARK-2 when correlated with clinical parameters resulted in significant association with tumor stage (p = 0.002) and with histological grade (p = 0.025). However, only clinical stage remained significant after Bonferroni correction (p < 0.007). A trend was observed between PARK-2 promoter hypermethylation and its protein expression. Our study provided sufficient information and insight for investigation of PARK-2 and highlighted its role as a tumor suppressor gene in cervical cancer in North Indian population.
Epidemiology of Verocytotoxigenic Escherichia Coli (Vtec) Non O157 Serotypes in Cattle in Abuja, Nigeria

The most frequently implicated E. coli serotype causing haemorrhagic colitis and haemorrhagicuraemic syndrome (HUS) is VTEC 0157. However, non – O157 VTEC is now known to be as prevalent as VETC O157 infection (or even more) in most parts of the world. The objective of the study was to establish the occurrence of non O157 VTEC serotypes in cattle in the Federal Capital Territory (FCT) Abuja, Nigeria. The level of significance of the infection with sex, age and season were also tested. The research work took place at Abuja, the capital of Nigeria. Abuja lies between 6o 45’and 7o 45’East of the Greenwich meridian and 8o and 9o. 25’North of the Equator. The cross sectional epidemiological method and multi staged sampling technique were used in this study. Samples were collected from the freshly voided faeces of both apparently healthy and diarrhoeic cattle in selected abattoirs and cattle herds. Enriched samples were analyzed bacteriologically and biochemically after which they were characterised using commercially prepared latex agglutination test kits. A total of 718 faecal samples from cattle were analyzed for the presence of VTEC non O157. Thirty eight (5.23%) were positive for non O157. No significant difference (p > 0.05) existed between O157 VTEC infection and sex of the cattle. A significant difference was found between age and infection with non O157 cattle. More calves were associated than the adult cattle. There was also a significant association (P < 0.05) between season and infection with non O157VTEC in cattle. Infection occurred more in the dry season. The study established the occurrence and prevalence of non O157VTEC in cattle in FCT, Abuja, Nigeria. As a major food animal in Nigeria, infection in cattle provides an epidemiological causal association to the infection in humans. The result showed that warmer seasons (dry season) stimulate the presence of VTEC infection in animals and thus, as a consequence, increases the number of human cases. The prevalence was also higher in younger calves (< 6 months) probably as a result of undeveloped immune system.
PAN-ARABISM AND ITS COMPETITORS: ISLAMIC RADICALS AND THE NATION STATE

Abstract Islamism may already be showing signs of meeting a more powerful ideological force: state nationalism. Islamists devote far more energy to attempting to take over existing states than to attacking the West. It is conceivable that, as with Pan-Arabism before it, the grandiose ideals of Islamism will be no match for the economic, military, and media might of the nation-states into which both Arabs and Muslims are separated. These appear to shape people's identity even more than do their potentially revolutionary shared religious tenets.
In Search of Management: Culture, Chaos and Control in Managerial Work

This book aims to cover the sorts of issues that managers constantly face: competencies; empowerment; chaos; culture change; survival; and competition. How do they understand these terms and apply them in their everyday lives? Tony Watson looks at the nature of managerial skill and organizational effectiveness, asking managers what it is they think they do, what power do they really have, how they manage under increasing pressure and whether they feel in control. By searching for a definition of management from managers themselves, Tony Watson draws a picture of the way managers shape their own lives and identities at the same time as shaping the organization's work activities. This book should be of interest to all those studying management, particularly MBA and other post-experience qualifications, as well as the general manager. The author has also published "Sociology, Work and Industry" (Routledge 1987), "Management, Organization and Employment Strategy" (Routledge, 1986), "Sociology, Work and Industry" (Routledge, 1980), and "The Personnel Managers" (Routledge, 1977).
Missing the forest for the trees?: Incongruous local perspectives on ecotourism in Nicaragua converge on ethical issues

Recent writings on ethics in tourism do little to represent local hosts' perceptions of the ethical nature of tourism and instead focus primarily on the role of industry and tour operators. In this paper, we bring local perceptions to the fore in comparing the ideal and the real in ecotourism. Using ethnographic observations and interviews, we describe how local residents near an ecotourism lodge along the Pacific Coast of Nicaragua first perceive and assess the ideals and sustainability of ecotourism in locally-grounded, realistic ways, often taking into account the broader social, economic, and environmental context of Nicaragua. Though people tend to be highly critical of the operation, they also acknowledge many relative merits of the ecotourism project's work. We then focus on narratives related to the ethical performance of this project. Here, people were less generous in their remarks and found little about the ecotourism project to support. This analysis demonstrates how failing to capture critica.

Non-Line-of-Sight Mobile Positioning Using Factor Graphs

Utilizing time-of-arrival measurements, we propose a recursive algorithm for estimating the location of a mobile station in a non-line-of-sight environment. By formulating the problem in a factor graph framework, messages are iteratively passed to obtain the mobile station position. Numerical results show that the proposed algorithm is more computationally attractive or reliable than existing methods and is able to achieve performance very close to the optimum benchmarks.
To each according to his needs: Dimensioning video buffer for specific user profiles and behavior

Today's video streaming platforms offer videos in a variety of quality settings in order to attract as many users as possible. But even though a sufficiently dimensioned network can not always be provided for the best experience, users are asking for high QoE. Users consume the content of a video streaming platform in different ways, while video delivery platforms currently do not account for these scenarios and thus ensure at best mediocre QoE. In this paper, we develop a queuing model and provide a mean-value analysis to investigate the impact of user profiles on the QoE of HTTP Video Streaming for typical user scenarios. Our results show that the user profile and particularly the scenario have to be respected when dimensioning the buffer. Further, we present recommendations on how to adapt player parameters in order to optimize the QoE for individual users profiles and viewing habits. The provided model leads to relevant insights that are required to build a system that guarantees each user the best attainable QoE.
Metabolic effects of dehydroepiandrosterone replacement therapy in postmenopausal women.

OBJECTIVE To investigate whether long-term treatment with dehydroepiandrosterone (DHEA) in postmenopausal women can modify insulin sensitivity and plasma lipid profile. DESIGN AND METHODS Twenty healthy postmenopausal women with serum dehydroepiandrosterone sulfate (DHEA-S) concentrations <2.5 micromol/l were enrolled and randomly assigned to two different treatment groups: group 1 were treated with micronized DHEA, 25 mg/day at 0800 h for 12 months; group 2 were treated with an identical placebo tablet. At the beginning and at the end of the study, plasma lipid profile, glucose tolerance (oral glucose tolerance test) and insulin sensitivity (euglycemic hyperinsulinemic clamp: M index) were assessed. RESULTS After 12 months, the group treated with DHEA showed a considerable improvement of insulin sensitivity (M index +29.55%, P=0.01) and lipid pattern (high-density lipoprotein cholesterol +11.61%, P=0.03; low-density lipoprotein cholesterol -11.07%, P=0.04; triglycerides -19.60%, P=0.03), but glucose tolerance did not change. No modifications were observed in the placebo group. CONCLUSIONS Long-term treatment with DHEA ameliorates some metabolic parameters that are linked to increased cardiovascular risk and, consequently, this seems to be an interesting therapeutic tool in the management of the postmenopausal syndrome.
The Effects of Acute Stress on Performance: Implications for Health Professions Education

Purpose This paper is a review of representative research on the impact of acute stressors on the clinical performance of individuals and teams. Method The Sciences Citation Index, Medline, and Psychinfo were used to search for articles up to and including 2008. The search terms were stress/tension/arousal/anxiety/cortisol/threat, cognition/skills/memory/attention/problem solving/decision making/performance, stress reduction/stress exposure/stress management/stress inoculation, and health professionals/medicine/medical students/residents/physicians/teams. The search was limited to papers in English from all developed countries. Secondary references were selected from primary papers. Results Elevated stress levels can impede performance on tasks that require divided attention, working memory, retrieval of information from memory, and decision making. These effects appear to be determined by the individual’s appraisal of the demands and resources of a situation, the relationship between the stressor and the task, and factors such as coping styles, locus of control, and social supports. Conclusions Given the potential negative impact of stress on performance, and the individualistic way in which people respond, medical educators might want to consider avenues for training learners in stress management. More research is needed to fully understand the contributions of personal factors such as coping style and locus of control, as well as the relationship of perceptions of stress to issues such as fatigue.
The test-retest reliability of a battery of new occupational performance assessments

Aims: The purpose of this pilot study was to investigate the test-retest reliability of a set of newly developed occupational performance assessment instruments based on the philosophy of pragmatism and the complexity theory. These instruments were: the Assessment and Intervention Instrument for Instrumentalism in Occupational Therapy (AIIIOT), the Daily Occupational Inventory (DOI), and the Occupational Performance Calculation Guide (OPCG). Method: An experimental study with a non-experimental test-retest design was adopted to quantify observations, and to determine the ability of the instruments to produce stable scores on repeated testing. Findings: The AIIIOT was found to have low test-retest reliability, probably owing to a very small sample. The occupational performance scores as calculated on the OPCG had reliability coefficients that approached statistical significance. Adequacy, Satisfaction, and Belief scores on the AIIIOT were found to be good predictors of the frequency of engagement in occupa.
Cyberporn and moral panic: an evaluation of press reactions to pornography on the internet.

A summary of the MA Dissertation which won the 2002 Library and Information Research Group Student Prize. The aim of the Dissertation was to find out if there had been a moral panic in the British press over Internet content. The paper briefly looks at the background to the Study. The term “moral panic” is defined in terms of Stanley Cohen’s (1972) model and put into context. The Literature Review looks at whether there has been a moral panic over Internet content in the USA, and at the situation in Britain. The legal and regulatory context is explored. The methodology of the Study is then discussed, considering which media were chosen and why, the timescale of the Study and how the data was collected and analysed. The limitations of the methodology are reviewed. The results are then presented, with an explanation of how they coincide with Cohen’s model. The Study concludes that there has been a moral panic over Internet content, which began in the latter half of 1995. Options for future study into this area are then offered.
