    To evaluate an alternative index for periodic leg movements during sleep (PLMS) and wakefulness (PLMW) expected to be similar to the standard index when leg movement activity is genuinely periodic, but significantly lower when periodicity is low. One-hundred-and-seven subjects with restless legs syndrome (RLS) were retrospectively identified and included (47 males, 60 females, mean age 56.9 years), along with 63 controls (33 males, 30 females, 42.2 years). Night-to-night variability was analysed in a subgroup of 17 subjects with RLS. PLMW were evaluated in a subgroup of 66 RLS subjects. Two 'alternative' PLMS/PLMW indices were calculated: one increased the lower limit of the inter-movement intervals from 5 to 10 s ('Alt1') and another additionally considered only series not interrupted by LMs with a short inter-movement interval ('Alt2'). Despite a high correlation between methods, only the Alt2 algorithm provided significantly different results, with PLMS/PLMW indices being consistently lower than those provided by the other two methods. The difference was more evident in the controls and during wakefulness, when periodicity was lower. The difference between the Alt2 and the standard PLMS index showed a significantly negative correlation with the Periodicity Index. Night-to-night variability was similar for all PLMS indices and significantly higher than the variability seen in the Periodicity Index. This methodological study introduces an alternative to the standard PLMS/PLMW indices, initiating the validation process for a new way of computing the PLMS/PLMW index, more adherent to the parameters that allows a reliable evaluation of their periodicity.

    2014-09-01

    Despite several polysomnographic studies on periodic leg movements (PLM) in healthy sleep, data on the prevalence and characteristics of periodic arm movements (PAM) in normal subjects are lacking. We aimed to investigate PAM and their association with PLM during wakefulness and sleep in healthy subjects. Ninety-one participants underwent video-polysomnography according to American Academy of Sleep Medicine 2007 criteria. In addition to standard electromyographic registration, data for both flexor digitorum superficialis muscles were recorded. Sixty-two subjects (68.1%) had a PAM index during wakefulness >5/h (median PAM index during wakefulness, 8.8/h; range, 0-77). Seven subjects (7.7%) had a PAM index >5/h during sleep (median PAM index during sleep, 0.7/h; range, 0-47.4). In 14% of cases, PAM during wakefulness were coincident with PLM during wakefulness. During sleep, this coincidence was not evident. The correlation between PAM and PLM was weak to moderate (during wakefulness: Spearman's ρ = 0.576, P sleep: Spearman's ρ = 0.222, P = 0.036). In healthy subjects, PAM occur predominantly during wakefulness with no apparent true periodicity. In contrast to classical PLM, some PAM may not present a true periodic phenomenon, but rather random voluntary movements meeting the wide range of periodicity criteria for PLM.

    With increasing life expectancy and ICU admission of elderly patients, mechanical ventilation, and weaning trials have increased worldwide. We evaluated a cohort with 479 subjects in the ICU. Patients younger than 18 y, tracheostomized, or with neurologic diseases were excluded, resulting in 331 subjects. Subjects ≥70 y old were considered elderly, whereas those elderly. Besides the conventional weaning indexes, we evaluated the performance of the integrative weaning index (IWI). The probability of successful weaning was investigated using relative risk and logistic regression. The Hosmer-Lemeshow goodness-of-fit test was used to calibrate and the C statistic was calculated to evaluate the association between predicted probabilities and observed proportions in the logistic regression model. Prevalence of successful weaning in the sample was 83.7%. There was no difference in mortality between elderly and non-elderly subjects (P = .16), in days of mechanical ventilation (P = .22) and days of weaning (P = .55). In elderly subjects, the IWI was the only respiratory variable associated with mechanical ventilation weaning in this population (P elderly subjects that may contribute to the critical moment of this population in intensive care.

    The physiological changes in obese subjects can modify the pharmacokinetic profiles of drugs influencing the therapeutic efficacy. In this study, the authors compare plasma dapsone trough levels of multibacillary leprosy subjects stratified by body mass index (BMI) to evaluate if obesity plays a significant role on drug levels. The relationship between drug levels and BMI was also determined. Dapsone was measured by high-performance liquid chromatography and BMI based on World Health Organization criteria. At steady state, the median plasma dapsone trough level was significantly lower in obesity class 2 group, when compared with other groups, but they were similar between normal weight and preobesity groups. A weak association between drug levels and BMI was observed. Obesity promotes a significant reduction in plasma dapsone trough levels of subjects with multibacillary leprosy with a weak association between drug levels and BMI.

  20. Periodical rocking long period gratings in PANDA fibers for high temperature and refractive index sensing

    2017-09-01

    We report periodical rocking long period gratings (PR-LPGs) in PANDA fibers fabricated with CO2 laser. The PR-LPGs achieve very high coupling efficiency of 19 dB with 12 periods and a 3.5° twist angle in just one scanning cycle, which is much more effective than the conventional CO2 laser fabrication technique. This type of LPGs exhibits polarization-selective resonance dips which demonstrate different sensitivities to environmental parameters. The high temperature and external refractive index sensitivities are measured simultaneously, so it can be used as a wavelength-selective polarization filter and sensor.

  1. Accuracy of medical subject heading indexing of dental survival analyses.

    Layton, Danielle M; Clarke, Michael

    2014-01-01

    To assess the Medical Subject Headings (MeSH) indexing of articles that employed time-to-event analyses to report outcomes of dental treatment in patients. Articles published in 2008 in 50 dental journals with the highest impact factors were hand searched to identify articles reporting dental treatment outcomes over time in human subjects with time-to-event statistics (included, n = 95), without time-to-event statistics (active controls, n = 91), and all other articles (passive controls, n = 6,769). The search was systematic (kappa 0.92 for screening, 0.86 for eligibility). Outcome-, statistic- and time-related MeSH were identified, and differences in allocation between groups were analyzed with chi-square and Fischer exact statistics. The most frequently allocated MeSH for included and active control articles were "dental restoration failure" (77% and 52%, respectively) and "treatment outcome" (54% and 48%, respectively). Outcome MeSH was similar between these groups (86% and 77%, respectively) and significantly greater than passive controls (10%, P indexed as such. Significantly more time-related MeSH were allocated to the included than the active controls (92% and 79%, respectively, P = .02), or to the passive controls (22%, P < .001). MeSH allocation within MEDLINE to time-to-event dental articles was inaccurate and inconsistent. Statistical MeSH were omitted from 30% of the included articles and incorrectly allocated to 15% of active controls. Such errors adversely impact search accuracy.

  2. On indexes and subject matter of “global competitiveness”

    2017-01-01

    Full Text Available The aim of the research is to analyze the subject matter of a country’s competitiveness and to characterize statistical indexes of competitiveness known in the international practice from the perspective of a more elaborated theory of market competition. This aim follows from the identified problems. First, there are no generally accepted interpretation and joint understanding of competition and competitiveness at country level. Even the international organizations giving estimations of global competitiveness disagree on definitions of competitiveness. Secondly, there is no relation to the theory of market competition in the available source materials on competitiveness of the country without original methodology. Thirdly, well-known statistical indexes of global competitiveness do not have enough theoretical justification and differ in sets of factors. All this highlights the incompleteness of the methodology and methodological support of studying competitiveness at country level.Materials and methods. The research is based on the methodology of statistics, economic theory and marketing. The authors followed the basic principle of statistical methodology – requirement of continuous combination of qualitative and quantitative analysis, when the research begins and ends with qualitative analysis. A most important section of statistical methodology is widely used – construction of statistical indexes. In the course of the analysis, a method of statistical classifications is applied. A significant role in the present research is given to the method of generalizing and analogue method, realizing that related terms should mean similar and almost similar contents. Modeling of competition and competitiveness is widely used in the present research, which made it possible to develop a logical model of competition following from the competition theory.Results. Based on the definitions’ survey the analysis of the subject matter of global

    2014-01-01

    Full Text Available Species living in a fluctuating medium and human exploitation activities might result in the duration of continuous changes. Such changes can be well-approximated as feedback controls. In this contribution a periodic discrete competitive system subject to feedback controls is proposed. By using the methods of discrete inequality, fixed point theorem, and analysis techniques, a good understanding of the existence and global asymptotic stability of positive periodic solutions is obtained. Some numerical investigations are provided to verify our analytical results.

  4. Higher Body Mass Index Is Associated with Subjective Olfactory Dysfunction

    2015-01-01

    Full Text Available Background. Morbidly obese patients demonstrate altered olfactory acuity. There has been no study directly assessing Body Mass Index (BMI in patients with olfactory dysfunction. Our purpose was to compare BMI in a group of patients with subjective olfactory dysfunction to those without subjective olfactory complaints. Methods. Retrospective matched case-control study. Sixty patients who presented to a tertiary care otolaryngology center with subjective smell dysfunction over one year were identified. Neoplastic and obstructive etiologies were excluded. Demographics, BMI, and smoking status were reviewed. Sixty age, gender, and race matched control patients were selected for comparison. Chi-square testing was used. Results. 48 out of 60 patients (80% in the olfactory dysfunction group fell into the overweight or obese categories, compared to 36 out of 60 patients (60% in the control group. There was a statistically significant difference between the olfactory dysfunction and control groups for this stratified BMI (p= 0.0168.  Conclusion. This study suggests high BMI is associated with olfactory dysfunction. Prospective clinical research should examine this further to determine if increasing BMI may be a risk factor in olfactory loss and to elucidate what role olfactory loss may play in diet and feeding habits of obese patients.

  5. Subjective sleep quality and suggested immobilization test in restless leg syndrome and periodic limb movement disorder.

    2002-06-01

    The severity of restless leg syndrome (RLS) and/or periodic limb movement disorder (PLMD) was investigated by using a suggested immobilization test (SIT) and by measuring the influence of these disorders on the subjective sleep quality as assessed by the Pittsburgh Sleep Quality Index (PSQI). Patients with RLS and those with both RLS and PLMD showed remarkably high values for PSQI and SIT, whereas patients with PLMD only showed normal values for PSQI. These findings suggest that there is only a small pathological significance for periodic limb movements, and demonstrate the efficacy of SIT and PSQI for evaluating the severity of these disorders.

  6. Equilibrium states of generic quantum systems subject to periodic driving.

    Science.gov (United States)

    Lazarides, Achilleas; Das, Arnab; Moessner, Roderich

    2014-07-01

    When a closed quantum system is driven periodically with period T, it approaches a periodic state synchronized with the drive in which any local observable measured stroboscopically approaches a steady value. For integrable systems, the resulting behavior is captured by a periodic version of a generalized Gibbs ensemble. By contrast, here we show that for generic nonintegrable interacting systems, local observables become independent of the initial state entirely. Essentially, this happens because Floquet eigenstates of the driven system at quasienergy ω(α) consist of a mixture of the exponentially many eigenstates of the undriven Hamiltonian, which are thus drawn from the entire extensive undriven spectrum. This is a form of equilibration which depends only on the Hilbert space of the undriven system and not on any details of its Hamiltonian.

  7. Improved Refractive Index Sensitivity Utilizing Long-Period Gratings with Periodic Corrugations on Cladding

    2012-01-01

    Full Text Available A new structure of Long-Period Gratings (LPGs sensor is introduced as a sensitive ambient RI sensor. This structure consists of creating periodic corrugations on the cladding of the LPG. The experimental results show that this LPG structure has good performances in terms of linearity and sensitivity and serves as a highly sensitive and cost-effective sensor. It also has the advantage of portability as the corrugation can also serve as the reservoir for the specimen collection to be tested.

  4. Accurate Computation of Periodic Regions' Centers in the General M-Set with Integer Index Number

    Directory of Open Access Journals (Sweden)

    Wang Xingyuan

    2010-01-01

    Full Text Available This paper presents two methods for accurately computing the periodic regions' centers. One method fits for the general M-sets with integer index number, the other fits for the general M-sets with negative integer index number. Both methods improve the precision of computation by transforming the polynomial equations which determine the periodic regions' centers. We primarily discuss the general M-sets with negative integer index, and analyze the relationship between the number of periodic regions' centers on the principal symmetric axis and in the principal symmetric interior. We can get the centers' coordinates with at least 48 significant digits after the decimal point in both real and imaginary parts by applying the Newton's method to the transformed polynomial equation which determine the periodic regions' centers. In this paper, we list some centers' coordinates of general M-sets' k-periodic regions (k=3,4,5,6 for the index numbers α=−25,−24,…,−1 , all of which have highly numerical accuracy.

  5. Refraction index sensor based on phase resonances in a subwavelength structure with double period.

    Skigin, Diana C; Lester, Marcelo

    2016-10-01

    In this paper, we numerically demonstrate a refraction index sensor based on phase resonance excitation in a subwavelength-slit structure with a double period. The sensor consists of a metal layer with subwavelength slots arranged in a bi-periodic form, separated from a high refraction index medium. Between the metallic structure and the incident medium, a dielectric waveguide is formed whose refraction index is going to be determined. Variations in the refraction index of the waveguide are detected as shifts in the peaks of transmitted intensity originated by resonant modes supported by the compound metallic structure. At normal incidence, the spectral position of these resonant peaks exhibits a linear or a quadratic dependence with the refraction index, which permits us to obtain the unknown refraction index value with a high precision for a wide range of wavelengths. Since the operating principle of the sensor is due to the morphological resonances of the slits' structure, this device can be scaled to operate in different wavelength ranges while keeping similar characteristics.

    The objective of the present study was to evaluate the effects of drinking 2 additional litres of water/day on several urinary risk factors for lithiasis in healthy subjects, through measurement of crystallization risk indices (Tiselius CRI). 48 healthy subjects, aged 25 to 50 were studied for urinary parameters including CRI in the laboratory ward, for 24 hours. After this first period, they were randomized either to a 2L/d additional water intake (treated group) or usual fluid consumption (control group) for a 6 days period, which ended by a second measurement period in the laboratory ward for 24 hours. Total additional water intake was actually 1.3L/d on average in treated subjects, because subjects decreased other usual sources of fluid intake. In 24 hour urine, Tiselius CRI varied differently among treated subjects and controls between the 2 periods; male controls subjects experienced much higher values (above 2 in average in first morning urine sample) in the second period (p = 0.05). Of interest, in a transversal analysis, we observed a positive relation between BMI or waist circumference on the one hand, and with 24 hour urea excretion or osmotic load on the other hand. These results show a beneficial effect of a final 1.3L additional water intake on Tiselius CRI in healthy subjects.

    Radiation of electromagnetic waves by a uniformly moving charge is the subject of extensive research over the last several decades. Fascinating effects such as Vavilov-Cherenkov radiation, transition radiation and the Smith-Purcell effect were discovered and studied in depth. In this letter we study the radiation of a line charge moving with relativistic constant velocity within an average zero index metamaterial consisting of periodically alternating layers with negative and positive refractive index. We observe a strong radiation enhancement, ~3 orders of magnitude, for specific combinations of velocities and radiation frequencies. This surprising finding is attributed to a gigantic increase in the density of states at the positive/negative index boundary. Furthermore, we shed light on radiation effects of such a line charge propagating within the more "traditional" structure of periodically alternating layers consisting of positive and different refractive index with focus on frequencies satisfying the quarter wave stack and the half wave stack conditions. We show that the quarter-wave-stack case results in emission propagating vertically to the line charge trajectory, while the half-wave-stack results in negligible radiation. All these findings were obtained using a computationally efficient and conceptually intuitive computation method, based on eigenmode expansion of specific frequency components. For validation purposes this method was compared with the finite-difference-time-domain method.

    2017-10-01

    Light interaction with a columnar structure of InxAl1-xN where each column is a layered periodic helical medium with laterally graded refractive index is considered. It is demonstrated that such a columnar structure can be presented as a stack of layers with a gradient of the refractive index. To calculate reflectance in the proposed model, the 2 × 2 characteristic matrix method adopted for a gradient index medium was applied. The influence of the refractive indices (including absorption), parameters of the twisting, and thickness of the periodic structure on reflectance is studied. Cases of normal and oblique incident light are considered. The presented medium is a one-dimensional photonic crystal that can be utilized in many devices for light manipulation.

  10. Highly Sensitive Refractive Index Sensor Based on Adiabatically Tapered Microfiber Long Period Gratings

    Directory of Open Access Journals (Sweden)

    Choong Leng Ng

    2013-10-01

    Full Text Available We demonstrate a refractive index sensor based on a long period grating (LPG inscribed in a special photosensitive microfiber with double-clad profile. The fiber is tapered gradually enough to ensure the adiabaticity of the fiber taper. In other words, the resulting insertion loss is sufficiently small. The boron and germanium co-doped inner cladding makes it suitable for inscribing gratings into its tapered form. The manner of wavelength shift for refractive indices (RIs differs from conventional LPG, and the refractive index detection limit is 1.67 × 10−5.

    2011-01-01

    To determine the periodontal status and treatment needs among dental fluorosis subjects residing in Ennore, Chennai, using Community Periodontal Index of Treatment Needs (CPITN). All the subjects with dental fluorosis above 15 years of age, permanent residents of Ennore, were included in the study. Subjects with known systemic diseases and subjects with other intrinsic dental stains were excluded from the study. Periodontal status was estimated using CPITN and Dental fluorosis was recorded using Dean's Dental Fluorosis Index. The total number of study subjects was 1075, of which 489 were males and 586 were females. Males were predominantly affected with periodontal disease than females. This was found to be statistically significant (P=0.000). The association between Degree of Fluorosis and Periodontal Status is statistically significant (P=0.000). There was statistically significant difference in mean number of sextants between the degree of fluorosis in each of the periodontal status (P=0.000). The finding that the lower prevalence of shallow pockets in the study area, where the fluoride level in the drinking water ranges from 1.83 to 2.01 ppm, indicates that the use of fluoride in water is beneficial to the periodontal tissues.

    Hyperinsulinaemia has been suggested as an important factor for developing hypokalaemic paralysis in patients with thyrotoxic periodic paralysis (TPP). Since hyperinsulinaemia is a common feature of insulin resistance, there may be a causal relationship between insulin resistance and TPP. To compare insulin sensitivity between subjects with a history of TPP and others with a history of thyrotoxicosis without periodic paralysis. Insulin sensitivity measured by euglycaemic hyperinsulinaemic clamp and 75-g oral glucose tolerance test (OGTT) were performed nonselectively in 10 subjects with a history of TPP (TPP group) and 10 age- and sex-matched subjects with a history of simple thyrotoxicosis (control group). All participants had euthyroidism and fasting plasma glucose of TPP group were higher than that of the control group. One of 10 (10%) subjects in the TPP group and 6 of 10 (60%) in the control group had BMI of TPP group was higher than in the control group. The TPP group had lower insulin sensitivity than the control group. The subjects with a history of TPP were more obese and had lower insulin sensitivity than those with a history of simple thyrotoxicosis. Insulin resistance with compensatory hyperinsulinaemia may be a key feature of the pathogenesis of TPP.

    Arterial stiffness is an independent predictor for vascular diseases. Cardio-ankle vascular index (CAVI) is a new index of arterial stiffness. In the present study, we investigated the possible risk factors involving CAVI in hypertension and diabetes mellitus (DM) subjects. One thousand sixty-three subjects (M/F 533/530) from Shougang Corporation Examination Center were divided into four groups: healthy group (n = 639); hypertension group (n = 312); DM group (n = 58); and hypertension with DM group (n = 54). CAVI was measured by VS-1000 apparatus. Our results showed that CAVI was significantly higher in hypertension subjects with DM than in healthy and hypertension group, respectively (8.59 ± 1.08 vs 7.23 ± 1.10; 8.59 ± 1.08 vs 7.94 ± 1.33; both P hypertension subjects with DM compared with healthy and hypertension groups.

Objective: The objective of this report is to evaluate whether anodal transcranial direct current stimulation (tDCS over the temporal cortex influences short-period temporal ventricular repolarization dispersion and cardiovascular ANS control in elderly subjects. Subjects and methods: In 50 healthy subjects (29 subjects younger than 60 years and 21 subjects older than 60 years matched for gender, short-period RR and systolic blood pressure spectral variability, QT variability index (QTVI, and noninvasive hemodynamic data were obtained during anodal tDCS or sham stimulation. Results: In the older group, the QTVI, low-frequency (LF power expressed in normalized units, the ratio between LF and high-frequency (HF power, and systemic peripheral resistances decreased, whereas HF power expressed in normalized units and α HF power increased during the active compared to the sham condition (P<0.05. Conclusion: In healthy subjects older than 60 years, tDCS elicits cardiovascular and autonomic changes. Particularly, it improves temporal ventricular repolarization dispersion, reduces sinus sympathetic activity and systemic peripheral resistance, and increases vagal sinus activity and baroreflex sensitivity.

    To determine reference ranges for patient vital signs during the immediate postpartum period. A retrospective chart review collected data on the variables of interest for all women with 0-24-hour postpartum data available at two hospitals in the USA, between July 1, 2012, and January 31, 2015. Patients were excluded if they had received antihypertensives, uterotonics, or blood products. Regression lines, with 95% prediction intervals, were constructed for shock index, systolic blood pressure, heart rate, pulse pressure, and rate over pressure evaluation (ROPE) values. There were 8874 patients and 87 336 data measurements included in the analysis. During the 24 hours following delivery, an increase in ROPE values, and decreases in pulse pressure, heart rate, and systolic blood pressure were recorded for all patients; an increase in shock index was observed among patients who had cesarean deliveries. Anomalous values for the shock index (>1.0), and reference ranges for pulse pressure (21.09-69.32 mm Hg), ROPE (1.01-3.22 bpm/mm Hg), heart rate (51-112 bpm), and SBP (81-137 mm Hg) were generated. Specific reference ranges for patients during the postpartum period could be used in future studies to determine the parameters, or combinations of parameters, that perform best as early markers of hemodynamic compromise in women experiencing early postpartum hemorrhage. © 2017 International Federation of Gynecology and Obstetrics.

    The Medical Subject Headings (MeSH) is the National Library of Medicine (NLM) controlled vocabulary for indexing articles. Inaccuracies in the MeSH thesaurus have been reported for several areas including pharmacy. To assess the quality of pharmacy-specific MeSH assignment to articles indexed in pharmacy journals. The 10 journals containing the highest number of articles published in 2012 indexed under the MeSH 'Pharmacists' were identified. All articles published over a 5-year period (2008-2012) in the 10 previously selected journals were retrieved from PubMed. MeSH terms used to index these articles were extracted and pharmacy-specific MeSH terms were identified. The frequency of use of pharmacy-specific MeSH terms was calculated across journals. A total of 6989 articles were retrieved from the 10 pharmacy journals, of which 328 (4.7%) were articles not fully indexed and therefore did not contain any MeSH terms assigned. Among the 6661 articles fully indexed, the mean number of MeSH terms was 10.1 (SD = 4.0), being 1.0 (SD = 1.3) considered as Major MeSH. Both values significantly varied across journals. The mean number of pharmacy-specific MeSH terms per article was 0.9 (SD = 1.2). A total of 3490 (52.4%) of the 6661 articles were indexed in pharmacy journals without a single pharmacy-specific MeSH. Of the total 67193 MeSH terms assigned to articles, on average 10.5% (SD = 13.9) were pharmacy-specific MeSH. A statistically significant different pattern of pharmacy-specific MeSH assignment was identified across journals (Kruskal-Wallis P MeSH terms to articles indexed in pharmacy journals can be improved to further enhance evidence gathering in pharmacy. Over half of the articles published in the top-10 journals publishing pharmacy literature were indexed without a single pharmacy-specific MeSH. Copyright © 2015 Elsevier Inc. All rights reserved.

    Dietary guidelines recommend the daily consumption of fruits; however, healthy and type 2 diabetes mellitus (T2DM) subjects receive conflicting messages regarding ingestion of fruits, such as mango, because of its sugar content. We investigated the effects of high hydrostatic pressure (HHP) processing of fresh mango puree (MP) on the glycemic indexes (GIs) and postprandial glycemic responses of 38 healthy Mexican subjects in a randomized cross-over clinical trial. Physicochemical characterization of MP included sugar profiles by HPLC-ELSD, starch, fibers, moisture, viscosity, swelling capacity and solubility properties of alcohol insoluble residue (AIR). The mean GI for HHP-MP was significantly lower (32.7 ± 13.4) than that of unprocessed-MP (42.7 ± 19.5). A significantly higher proportion of subjects showed a low GI following the consumption of HHP-MP compared to unprocessed-MP and none of them showed a high GI for the HHP-MP, compared to a significantly higher proportion for the unprocessed-MP. The viscosity and AIR solubility values of HHP-MP samples were significantly higher, which influenced glucose peaking later (Tmax) at 45 minutes and induced 20% lower AUC values than unprocessed-MP, corresponding to greater retardation indexes. The study findings support data stating that low GI fruits are appropriate for glycemic control and that mango may be included as part of healthy subjects' diets and potentially T2DM subjects' diets. Furthermore, HHP processing of mango may offer additional benefits for glycemic control, as its performance regarding GI, AUC and Tmax was significantly better than that of the unprocessed-MP. To our knowledge, this is the first report on the impact of this commercial non-thermal pasteurization technology on glucose metabolism.

    Glycemic index of grain amaranth, wheat and rice preparations was studied in non-insulin dependent diabetic subjects. Diets containing 50 g carbohydrate equivalent were given and post-prandial blood glucose estimated at different intervals. Glycemic index calculated for different experimental diets showed that GI of amaranth-wheat composite flour diet (25:75) was the least (65.6%) followed by wheat diet (65.7%), rice diet (69.2%), amaranth-wheat flour 50:50 (75.5%), and popped amaranth in milk (97.3%). Therefore 25:75 combination of amaranth and wheat, wheat and rice can be considered low GI food, 50:50 grain amaranth and wheat medium GI food and popped amaranth and milk combination high GI food.

    Arterial stiffness is an independent predictor for vascular diseases. Cardio-ankle vascular index (CAVI) is a new index of arterial stiffness. However, there was little research about the CAVI value between different countries. The aim of the present study was to compare CAVI between Chinese and Japanese subjects and to assess related factors. 2519 healthy persons [1245 Chinese (M/F, 524/721) and 1274 Japanese (M/F, 534/740)] from the Department of Physical Examination were enrolled into our study. CAVI was recorded using a VaseraVS-1000 vascular screening system. CAVI was increasing with aging in all subjects. CAVI was significantly lower in Chinese compared with Japanese both in male and female. There was difference in lipid metabolism between these two groups. Multivariate analysis showed that age, systolic blood pressure (SBP), fasting plasma glucose (FPG), plasma creatinine (Cr) were significant independent associating factors of CAVI in Chinese persons (β = 0.548, p < 0.001; β = 0.129, p = 0.001; β = 0.105, p = 0.006; and β = 0.100, p = 0.012, respectively), whereas age, SBP, high-density lipoprotein cholesterol (HDL-C), Cr, body mass index (BMI), FPG were significant independent associating factors of CAVI in Japanese subjects (β = 0.669, p < 0.001; β = 0.198, p < 0.001; β = -0.079, p < 0.001; β = 0.090, p < 0.001; β = -0.124, p < 0.001; β = 0.055, p=0.009; respectively). CAVI was increasing with aging in both Chinese and Japanese subjects. CAVI was significantly lower in Chinese than in Japanese subjects. Age, SBP, FPG and creatinine were independently associated with CAVI in both Chinese and Japanese subjects.

    This study aims to understand how different reference periods (i.e., calibration periods) of climate data used to estimate drought indices influence regional drought assessments. Specifically, we investigate the influences of different reference periods on historical drought characteristics, such as the trend, frequency, intensity and spatial extent, using the standardized precipitation evapotranspiration index (SPEI) with a 12-month lag (SPEI-12), which was estimated from the datasets of the Climate Research Unit (CRU) and the University of Delaware (UDEL). For the 1901-1957 (P1) and 1958-2014 (P2) estimation periods, three different types of reference periods are used to compute the SPEI: P1 and P2 together, P1 and P2 separately and P1 only. Focusing on East Asia, Europe, the United States and West Africa, we find that the influence of the reference period is significant in East Asia and West Africa, with dominant drying trends from P1 to P2. The reference period influenced the assessment of drought characteristics, particularly the severity and spatial extent, whereas the influence on the frequency was relatively small. Finally, self-calibration, which is the most common practice for indices such as the SPEI, tends to underestimate the drought severity and spatial extent relative to the other approaches used in this study. Although the conclusions drawn in this study are limited by the use of two global datasets, they highlight the need for clarification of the reference period in drought assessments to better understand regional drought characteristics and the associated temporal changes, particularly under climate change scenarios.

    Aim. To study the evolution of impaired fasting glucose (IFG), considering glucose and HbA1c levels and risk factors associated, in a period of 6 years. Methods. We studied 94 subjects with impaired fasting glucose (IFG) that were diagnosed in 2005 and followed up to 2012. Glucose and HbA1c levels were determined. A descriptive analysis of contingence charts was performed in order to study the evolution in the development of type-2 diabetes mellitus (T2DM). Results. Twenty-eight of ninety-four subjects became T2DM; 51/94 remained with IFG; and 20/94 presented normal fasting glucose. From the 28 diabetic subjects, 9 had already developed diabetes and were under treatment with oral hypoglycemic agents; 5 were diagnosed with plasma glucose < 126 mg/dL, but with HbA1c over 6.5%. In those who developed diabetes, 15/28 had a family history of T2DM in first relative degree. Also, diabetic subjects had a BMI significantly higher than nodiabetics (t test: P < 0.01). The individuals that in 2005 had the highest BMI are those who currently have diabetes. Conclusion. The IFG constitutes a condition of high risk of developing T2DM in a few years, especially over 110 mg/dL and in obesity patients. PMID:25215305

    Full Text Available Night temperatures have shown an increase in rice-growing regions due to climate change in Colombia in recent years, causing a reduction in grain yield. The objective of this research was to study the effect of four different periods of exposure to two night temperatures (24°C vs. 30°C on the physiological behavior of an Indica rice cultivar widely grown in Colombia. Fedearroz 60 (ʻF60ʼ were grown under greenhouse conditions for forty-five days. After this period, 12 plants in each treatment was established in a growth chamber at 30°C from 18:00 to 24:00 to carry out the duration of the different periods of heat nighttime stress (4, 8, 12, and 16 days respectively. The control plants were kept in a greenhouse at 24°C. The results showed that leaf photosynthesis, carboxylation efficiency, and pigment content decreased in rice seedlings subjected to 30°C. Also, dark respiration and intercellular CO2 concentration increased. These reductions in the variables as mentioned above were more severe during the first four days of exposure to 30°C than 24°C. In conclusion, these results suggest that these physiological variables may be useful to assess the tolerance of rice plants to high nighttime temperatures in plant breeding programs.

    Circadian clock genes are critical regulators of energy homeostasis and metabolism. However, whether variation in the circadian genes is associated with metabolic phenotypes in humans remains to be explored. In this study, we systemically genotyped 20 tag single nucleotide polymorphisms (SNPs) in 8 candidate genes involved in circadian clock, including CLOCK, BMAL1(ARNTL), PER1, PER2, CRY1, CRY2, CSNK1E,, and NOC(CCRN4L) in 1,510 non-diabetic Chinese subjects in Taipei and Yunlin populations in Taiwan. Their associations with metabolic phenotypes were analyzed. We found that genetic variation in the NOC gene, rs9684900 was associated with body mass index (BMI) (P = 0.0016, Bonferroni corrected P = 0.032). Another variant, rs135764 in the CSNK1E gene was associated with fasting glucose (P = 0.0023, Bonferroni corrected P = 0.046). These associations were consistent in both Taipei and Yunlin populations. Significant epistatic and joint effects between SNPs on BMI and related phenotypes were observed. Furthermore, NOC mRNA levels in human abdominal adipose tissue were significantly increased in obese subjects compared to non-obese controls. Genetic variation in the NOC gene is associated with BMI in Chinese subjects.

    Full Text Available We reported a long period grating (LPG written in specially designed photonic crystal fiber (PCF for refractive index (RI sensing by interrogating the transmitted light power. The outermost ring of clad holes of the PCF is enlarged where the analyte is filled. We showed that the leakage loss of the clad mode increases with the RI in the larger holes. By numerically analyzing the complex couple mode equations for the core mode and the first clad mode, we found the depth of attenuation band in the transmitted spectra and the total transmitted power is sensitive to the leakage loss of the clad mode or the RI in the larger holes. We also demonstrated that the transmitted power is sensitive to the RI even less than that of the silica, which just avoids the limitation that the transmitted light power of LPG in conventional fiber is only sensitive to the RI of the external media higher than that of fiber clad.

    The purpose of this study is to measure and analyze the characteristics in change of EMG and EEG parameters at muscle fatigue period in participants with different exercise capacity. Twenty participants took part in the tests. They were divided into two groups, Group A (constant exerciser) and Group B (seldom-exerciser). MVC dynamic and 1/3 isometric exercises were performed; EMG and EEG signals were recorded synchronously during different type of muscle contraction. Results indicated that values of MVC, RMS and IEMG in Group A were greater than Group B, but isometric exercise time was shorter than the time of dynamic exercise although its intensity was light. Turning point of IEMG and α Index occurred synchronously during constant muscle contraction of isometric or dynamic exercise. It is concluded that IEMG turning point may be an indication to justify muscle fatigue. Synchronization of EEG and EMG reflects its common characteristics on its bio-electric change.

  11. A general symplectic method for the response analysis of infinitely periodic structures subjected to random excitations

    Directory of Open Access Journals (Sweden)

    You-Wei Zhang

    Full Text Available A general symplectic method for the random response analysis of infinitely periodic structures subjected to stationary/non-stationary random excitations is developed using symplectic mathematics in conjunction with variable separation and the pseudo-excitation method (PEM. Starting from the equation of motion for a single loaded substructure, symplectic analysis is firstly used to eliminate the dependent degrees of the freedom through condensation. A Fourier expansion of the condensed equation of motion is then applied to separate the variables of time and wave number, thus enabling the necessary recurrence scheme to be developed. The random response is finally determined by implementing PEM. The proposed method is justified by comparison with results available in the literature and is then applied to a more complicated time-dependent coupled system.

  12. Usage and Impact of Controlled Vocabularies in a Subject Repository for Indexing and Retrieval

    Full Text Available Since 2009, the German National Library for Economics (ZBW supports both indexing and retrieval of Open Access scientific publications like working papers, postprint articles and conference papers by means of a terminology web service. This web service is based on concepts organized as a ‘Standard Thesaurus for Economics’ (STW, which is modelled and regularly published as Linked Open Data. Moreover, it is integrated into the institution’s subject repository for automatically suggesting appropriate key words while indexing and retrieving documents, and for automatically expanding search queries on demand to gain better search results. While this approach looks promising to augment ‘off the shelf’ repository software systems in a lightweight manner with a disciplinary profile, there is still significant uncertainty about the effective usage and impact of controlled terms in the realm of these systems. To cope with this, we analyze the repository’s logfiles to get evidence of search behaviour which is potentially influenced by auto suggestion and expansion of scientific terms derived from a discipline’s literature.

  13. Absorption spectrum of a two-level system subjected to a periodic pulse sequence

    We investigate how the quantum control of a two-level system (TLS) coupled to photons can modify and tune the TLS's photon absorption spectrum. Tuning and controlling the emission and the absorption are of great interest, e.g., for the development of efficient interfaces between stationary and flying qubits in modern architectures for quantum computation and quantum communication. We consider periodic pulse control, where the TLS is subjected to a periodic sequence of the near-resonant Rabi driving pulses, each pulse implementing a 180∘ rotation. For small interpulse delays, the absorption spectrum features a pronounced peak of stimulated emission at the pulse frequency, similar satellite peaks with smaller spectral weights, and the net absorption peaks on the sides. As long as the detuning between the carrier frequency of the driving and the TLS transition frequency remains moderate, this spectral shape shows little change. Therefore, the pulse control allows shifting the absorption peak to a desired position and locks the overall absorption spectrum to the carrier frequency of the driving pulses. A detailed description of the spectrum and its evolution as a function time, the interpulse spacing, and the detuning is presented.

    This study sought to explore the effect of glycemic-index dietary carbohydrates on endothelium-dependent flow-mediated dilation (FMD) in overweight and obese nondiabetic volunteers. Post-prandial hyperglycemia has been recognized as a cardiovascular risk factor in both the diabetic and the general population. Endothelial dysfunction has been shown to occur in diabetic and hyperglycemic patients. We prospectively assessed brachial artery FMD in 56 healthy overweight and obese nondiabetic volunteers (38 [67.9%] men, mean age 48 +/- 6 years) on 4 separate mornings, 1 to 2 weeks apart. After overnight fasting, the percent FMD (%FMD) improvement and endothelium-independent nitroglycerin-mediated dilation (%NTG) were assessed, after which subjects received 1 of 4 group meals at each visit (placebo [water] or a carbohydrate meal of glucose, cornflakes, or high-fiber cereal). Meals were distributed in a rotating randomized fashion, such that each subject received all 4 meals once throughout the study period. Fasting and 2-h post-prandial serum glucose levels were similar in all 3 meals, whereas at 30 to 90 min, serum glucose levels were significantly higher after glucose and cornflakes (high glycemic) compared with fiber (low glycemic). Baseline %FMD, not significantly different in the 3 carbohydrate-based meals, was reduced 2 h post-prandially in all groups, showing statistical significance in only high-glycemic index meals: glucose (15 +/- 9% vs. 10 +/- 8%, p glycemic carbohydrate consumption significantly suppresses FMD in nondiabetic overweight and obese volunteers, suggesting a mechanism whereby high-glycemic meals may enhance cardiovascular risk.

    Background Little evidence on the validity of simple and widely applicable tools to predict mortality in patients with chronic obstructive pulmonary disease (COPD) exists. Objective To conduct a large international study to validate the ADO index that uses age, dyspnoea and FEV1 to predict 3-year mortality and to update it in order to make prediction of mortality in COPD patients as generalisable as possible. Design Individual subject data analysis of 10 European and American cohorts (n=13 914). Setting Population-based, primary, secondary and tertiary care. Patients COPD GOLD stages I–IV. Measurements We validated the original ADO index. We then obtained an updated ADO index in half of our cohorts to improve its predictive accuracy, which in turn was validated comprehensively in the remaining cohorts using discrimination, calibration and decision curve analysis and a number of sensitivity analyses. Results 1350 (9.7%) of all subjects with COPD (60% male, mean age 61 years, mean FEV1 66% predicted) had died at 3 years. The original ADO index showed high discrimination but poor calibration (p<0.001 for difference between predicted and observed risk). The updated ADO index (scores from 0 to 14) preserved excellent discrimination (area under curve 0.81, 95% CI 0.80 to 0.82) but showed much improved calibration with predicted 3-year risks from 0.7% (95% CI 0.6% to 0.9%, score of 0) to 64.5% (61.2% to 67.7%, score of 14). The ADO index showed higher net benefit in subjects at low-to-moderate risk of 3-year mortality than FEV1 alone. Interpretation The updated 15-point ADO index accurately predicts 3-year mortality across the COPD severity spectrum and can be used to inform patients about their prognosis, clinical trial study design or benefit harm assessment of medical interventions.

    Full Text Available Exercise training can improve blood pressure in normotensive, prehypertensive, and hypertensive subjects. One of the mechanisms of blood pressure reduction in hypertensive patients with obesity is through weight loss. This study aimed to examine the effect of exercise training on bodyweight and the relationship between weight loss and reduction of blood pressure. An experimental pre-post test design without controls was used to evaluate the effect of exercise training on weight loss. The study involved 89 elderly aged 50 years or more, consisting of 40 men and 49 women, who were members of Senayan Sport Fitness Club and had been exercising for at least three months. Exercise training was programmed and performed three times a week, consisting of aerobic (walking, jogging, static cycling, and resistance exercise. All exercise was performed for one to two hours with mild to moderate intensity. Blood pressure and body weight were obtained from medical records. Paired t-test showed that systolic blood pressure (SBP, diastolic blood pressure (DBP, mean arterial pressure (MAP, pulse pressure (PP, and body mass index (BMI were significantly lower after training [(systolic, 126.3 ± 2.9 vs 122.3 ± 2.7, p=0.02, (diastolic, 80.2 ± 3.1 vs 77.2 ± 2.4, p=0.00, (MAP, 95.6 ± 4.6 vs 92.2 ± 3.4, p=0.00, (PP, 46.1 ± 4.2 vs 45.1 ± 3.6, p=0.04, (BMI, 24.5 ± 2.9 vs 23.6 ± 2.9, p=0.04]. Duration of training was the most influential factor affecting rBMI, (Beta = 0.38; p=0.00. Exercise training could lower BMI and the reduction in diastolic blood pressure was higher for the subjects aged 70 years and over.

The study involved 89 elderly aged 50 years or more, consisting of 40 men and 49 women, who were members of Senayan Sport Fitness Club and had been exercising for at least three months. Exercise training was programmed and performed three times a week, consisting of aerobic (walking, jogging, static cycling, and resistance exercise. All exercise was performed for one to two hours with mild to moderate intensity. Blood pressure and body weight were obtained from medical records. Paired t-test showed that systolic blood pressure (SBP, diastolic blood pressure (DBP, mean arterial pressure (MAP, pulse pressure (PP, and body mass index (BMI were significantly lower after training [(systolic, 126.3 ± 2.9 vs 122.3 ± 2.7, p=0.02, (diastolic, 80.2 ± 3.1 vs 77.2 ± 2.4, p=0.00, (MAP, 95.6 ± 4.6 vs 92.2 ± 3.4, p=0.00, (PP, 46.1 ± 4.2 vs 45.1 ± 3.6, p=0.04, (BMI, 24.5 ± 2.9 vs 23.6 ± 2.9, p=0.04]. Duration of training was the most influential factor affecting rBMI, (Beta = 0.38; p=0.00. Exercise training could lower BMI and the reduction in diastolic blood pressure was higher for the subjects aged 70 years and over.

    The laparoscopic sleeve gastrectomy (LSG) is a successful surgical procedure for morbid obesity. However, post surgery weight regain is usual, thus applying the glycemic index could promote good weight control. To compare the glycemic index (GI) and glycemic response (GR) obtained of instant mashed potatoes in individuals subjected to LSG versus control subjects. GI and GR were assessed in 10 LSG subjects and compared with 10 controls. GI methodology proposed by FAO/WHO was used; instant mashed potatoes as test food and white bread as standard food (50g available CHO). Capillary blood sample 0 (fasting), 30, 60, 90 and 120 minutes. The GI was determined by trapezoidal method. ANOVA was used to compare a factor between RG and IG groups; t-student to compare RG between foods. Statistical significance pglycemic responses in LSG group, and its consumption possibly favoring weight regain. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

    Full Text Available Abstract Background Short and valid measures of the impact of a stroke on integration are required in health and social settings. The Subjective Index of Physical and Social Outcome (SIPSO is one such measure. However, there are questions whether scores can be summed into a total score or whether subscale scores should be calculated. This paper aims to provide clarity on the internal construct validity of the subscales and the total scale. Methods SIPSO data were collected as part of two parallel surveys of the met and unmet needs of 445 younger people (aged 18-65 with non-recent stroke (at least one year and living at home. Factor, Mokken and Rasch analysis were used. Results Factor analysis supported a two factor structure (explaining 68% of the variance as did the Mokken analysis (overall Loevinger coefficient 0.77 for the Physical Integration subscale; 0.51 for the Social Integration subscale. Both subscales fitted the Rasch model (P > 0.01 after adjusting for some observed differential item functioning. The 10-items together did not fit the Rasch model. Conclusions The SIPSO subscales are valid for use with stroke patients of working age but the total SIPSO is not. The conversion table can be used by clinicians and researchers to convert ordinal data to interval level prior to mathematical operations and other parametric procedures. Further work is required to explore the occurrence of bias by gender for some of the items.

    Mechanized maneuver training impacts the landscape by creating depressions, compacting soils, producing bare ground areas, transporting seeds of invasive plants, and crushing vegetation. We measured 3 physical, 13 chemical, and 2 biological soil properties and used a disturbance index (DI) based on perceptions of soil conditions on a military installation to assess the condition of 100 ?? 100 m plots (1 ha): 10 in 2002 and 10 in 2004. Potential DI scores range from 0 (no appreciable evidence of disturbance) to 1 (>95 per cent of the plot disturbed). Bulk density, porosity (%), and water content (%) - all at 5-1-10-0cm depth, and nematode family richness (NFR) were significantly, negatively correlated (Spearman coefficients, rs) with the DI of both years. The strong negative correlation (rs., = -0.69 in 2002, -0.79 in 2004) of NFR with the DI appears to reflect the status of nematode diversity and, therefore, may serve as a useful, inexpensive approach to rapidly assessing grasslands subjected to mechanized military training.

  3. Numerical Approach to Modeling and Characterization of Refractive Index Changes for a Long-Period Fiber Grating Fabricated by Femtosecond Laser

    Directory of Open Access Journals (Sweden)

    Akram Saad

    2016-11-01

    Full Text Available A 3D finite element model constructed to predict the intensity-dependent refractive index profile induced by femtosecond laser radiation is presented. A fiber core irradiated by a pulsed laser is modeled as a cylinder subject to predefined boundary conditions using COMSOL5.2 Multiphysics commercial package. The numerically obtained refractive index change is used to numerically design and experimentally fabricate long-period fiber grating (LPFG in pure silica core single-mode fiber employing identical laser conditions. To reduce the high computational requirements, the beam envelope method approach is utilized in the aforementioned numerical models. The number of periods, grating length, and grating period considered in this work are numerically quantified. The numerically obtained spectral growth of the modeled LPFG seems to be consistent with the transmission of the experimentally fabricated LPFG single mode fiber. The sensing capabilities of the modeled LPFG are tested by varying the refractive index of the surrounding medium. The numerically obtained spectrum corresponding to the varied refractive index shows good agreement with the experimental findings.

    Full Text Available In this paper, I claim that subjectivity is a way of being that is constituted through a set of practices in which the self is subject to the dangers of fictionalizing and plotting her life and self-image. I examine some ways of becoming subject through narratives and through theatrical performance before others. Through these practices, a real and active subjectivity is revealed, capable of self-knowledge and self-transformation.

    This study analyzed the publications of authors from Costa Rican institutions that were included in the Science Citation Index (SCI) during 1999-2001. Out of the 722 references detected, distributed in 328 journals, 90.7% corresponded to original research articles. The total productivity figures showed a moderately increasing trend, both in absolute and population-adjusted terms, in concordance with previous data recorded for the period 1980-1998. The contribution of Revista de Biología Tropical to these figures corresponded to 10.0%, 8.9%, and 19.1%, for the years 1999, 2000, and 2001, respectively. The subject distribution of articles followed a similar pattern to that described for 1980-1998, with a predominance of biomedical (33.3%) and biological (27.5%) sciences, followed by agronomical (15.5%) sciences, chemistry (13.6%), physics (5.0%), geological sciences (3.6%), and mathematics (1.5%). Citation analyses for individual publications (up to July 15, 2002) revealed that only 45.2% of the articles had been cited at least once. The ten most cited references were analyzed, varying from 26 to 114 citations. The average citation per article was 2.60, and the average number of authors per article was 2.92. In agreement with data from 1980-1998, the University of Costa Rica appeared as the institution with highest productivity of SCI publications during 1999-2001, with a contribution of 50.0%. The percentage of publications performed without the participation of foreign co-authors showed a change in its decreasing trend of 1980-1998, stabilizing near the range of 25-30% during the period 1999-2001.

    Sleep onset is associated with marked changes in behavioral, physiological, and subjective phenomena. In daily life though subjective experience is the main criterion in terms of which we identify it. But very few studies have focused on these experiences. This study seeks to identify the subjective variables that reflect sleep onset. Twenty young subjects took an afternoon nap in the laboratory while polysomnographic recordings were made. They were awakened four times in order to assess subjective experiences that correlate with the (1) appearance of slow eye movement, (2) initiation of stage 1 sleep, (3) initiation of stage 2 sleep, and (4) 5 min after the start of stage 2 sleep. A logistic regression identified control over and logic of thought as the two variables that predict the perception of having fallen asleep. For sleep perception, these two variables accurately classified 91.7% of the cases; for the waking state, 84.1%. Copyright © 2010 Elsevier Inc. All rights reserved.

    Abnormalities of sleep and biological rhythms have been widely implicated in the pathophysiology of major depressive disorder (MDD) and bipolar disorder (BD). However, less is known about the influence of biological rhythm disruptions across the perinatal period on postpartum depression (PPD). The objective of this study was to prospectively evaluate the relationship between subjective changes in both sleep and biological rhythms and worsening of depressive symptoms from pregnancy to the postpartum period in women with and without mood disorders. Eighty-three participants (38 euthymic women with a history of a mood disorder and 45 healthy controls) were studied. Participants completed subjective assessments of sleep (Pittsburgh Sleep Quality Index), biological rhythm disturbances (Biological Rhythms Interview of Assessment in Neuropsychiatry), and depressive symptoms (Edinburgh Postnatal Depression Scale) prospectively at two time points: third trimester of pregnancy and at 6-12 weeks postpartum. Multivariate regression analyses showed that changes in biological rhythms across the perinatal period predicted worsening of depressive symptoms in both groups. Moreover, women with a history of a mood disorder showed higher levels of sleep and biological rhythm disruption during both pregnancy and the postpartum period. These findings suggest that disruptions in biological rhythms during the perinatal period increase the risk for postpartum mood worsening in healthy pregnant as well as in pregnant women with a history of mood disorders.

    The suppressory effects of localized heterogeneous periodic pulses on the chaotic behaviour of sinusoidally coupled nonlinear pendula are studied. We assume that when the pendula are driven synchronously, i.e., all driving pulses have the same waveform, the chains display chaotic dynamics. It is shown that decreasing the impulse transmitted by the pulses of a minimal number of pendula results in regularization with the whole array exhibiting frequency synchronization over a wide range of coupling periods. These findings demonstrate that decreasing the impulse transmitted by localized external forces can tame chaos and lead to frequency-locked states in networks of periodically coupled dissipative systems.

    The purpose of this study was to determine the in vivo glycemic index of carob tablets with healthy subjects and to determine the in vitro glycemic index of carob tablets and carob flour by the hydrolysis index. Seven healthy volunteers consumed portions of carob tablets containing 26g of available carbohydrate. Their capillary blood was taken at intervals after carob or glucose consumption. The glycemic hydrolysis index by an in vitro technique was based in the release of glucose after enzymatic treatment of carob tablets and carob flour. The determination of the fiber content was performed using the enzymatic- gravimetric method. By the in vivo determination, the estimated glycemic index of carob tablets could be considered low (≤ 55). By the in vitro determination, the estimated glycemic index ranged from 40.1+0.02 of carob tablets to 40.6+0.05 of carob flour. The total fiber values obtained for carob flour samples were from 42.6% ± 0.49 to 42.9% ± 0.68 with no statistical significant differences between samples. Carob tablets and carob flour could be classified as low glycemic index food and low glycemic load food. Carob flour is a high fiber food, containing mainly high levels of insoluble fiber.

    This study examined the association between measures of objective sleep (OS) and subjective sleep (SS) to postpartum mood in healthy women from the third trimester of pregnancy to 10 to 12 weeks postpartum. Twenty-nine pregnant women completed self-report measures of mood and SS, and wore actigraphs for 7 continuous days during the third trimester (Time 1), within 15 days (Time 2), and 10 to 12 weeks postpartum (Time 3). The subjective perception of marked daytime dysfunction was associated with low mood during Time 1 and Time 3. Poor nighttime SS was related to low mood only at Time 2, whereas poor nighttime OS influenced stress during the same assessment time. These data indicate a stronger association between postpartum mood and the subjective perception of sleep than with OS quality and duration in healthy, non-depressed women, and highlight the awareness of poor daytime functioning as a significant contributor to new mothers' emotional wellbeing.

    2010-11-01

    To review the effects of dietary fiber and a low glycemic index diet on glycemic risk factors in people with type 2 diabetes mellitus (T2DM) or T2DM and dyslipidemia. Literature search was conducted using PubMed, Cochrane Library, The Natural Standard, and The Natural Medicines through July 2010 using the terms type 2 diabetes mellitus, dietary fiber, psyllium, and glycemic index. Articles included were randomized controlled studies or meta-analyses examining the effects of dietary interventions (dietary fiber, low glycemic index diet, or psyllium) on glycemic risk factors (glycosylated hemoglobin A₁(c) [A1C] or postprandial plasma glucose [PPG] concentrations) in subjects with T2DM or T2DM and dyslipidemia. Both psyllium supplementation and low glycemic index diets have been studied as monotherapy in the treatment of T2DM. Seven studies were reviewed (3 randomized crossover studies, 1 randomized parallel study, 3 randomized blinded parallel studies). Individually, psyllium supplementation and a low glycemic index diet improved glycemic risk factors. PPG and A1C decreased with psyllium 10.2 g per day, while A1C decreased with a low glycemic index diet (average glycemic index 59). However, the results for the low glycemic index diet are controversial. One study was underpowered to detect changes in A1C, while another study had psyllium fiber as a confounding variable. Psyllium supplementation might be an additional therapeutic option for people with T2DM who are already receiving diabetes medication and who still experience elevated PPG concentrations. Further well-designed clinical trials and adjustment for confounding variables are needed to determine the role of a low glycemic index diet in the treatment of T2DM.

    CERN Document Server

    Day, Ronald E

    2014-01-01

    In this book, Ronald Day offers a critical history of the modern tradition of documentation. Focusing on the documentary index (understood as a mode of social positioning), and drawing on the work of the French documentalist Suzanne Briet, Day explores the understanding and uses of indexicality. He examines the transition as indexes went from being explicit professional structures that mediated users and documents to being implicit infrastructural devices used in everyday information and communication acts. Doing so, he also traces three epistemic eras in the representation of individuals and groups, first in the forms of documents, then information, then data. Day investigates five cases from the modern tradition of documentation. He considers the socio-technical instrumentalism of Paul Otlet, "the father of European documentation" (contrasting it to the hermeneutic perspective of Martin Heidegger); the shift from documentation to information science and the accompanying transformation of persons and texts i...

  20. Composite Estimation for Single-Index Models with Responses Subject to Detection Limits

    KAUST Repository

    Tang, Yanlin

    2017-11-03

    We propose a semiparametric estimator for single-index models with censored responses due to detection limits. In the presence of left censoring, the mean function cannot be identified without any parametric distributional assumptions, but the quantile function is still identifiable at upper quantile levels. To avoid parametric distributional assumption, we propose to fit censored quantile regression and combine information across quantile levels to estimate the unknown smooth link function and the index parameter. Under some regularity conditions, we show that the estimated link function achieves the non-parametric optimal convergence rate, and the estimated index parameter is asymptotically normal. The simulation study shows that the proposed estimator is competitive with the omniscient least squares estimator based on the latent uncensored responses for data with normal errors but much more efficient for heavy-tailed data under light and moderate censoring. The practical value of the proposed method is demonstrated through the analysis of a human immunodeficiency virus antibody data set.

    2017-11-01

    Electron spin dephasing in a singly charged semiconductor quantum dot can partially be suppressed by periodic laser pulsing. We propose a semiclassical approach describing the decoherence of the electron spin polarization governed by the hyperfine interaction with the nuclear spins as well as the probabilistic nature of the photon absorption. We use the steady-state Floquet condition to analytically derive two subclasses of resonance conditions excellently predicting the peak locations in the part of the Overhauser field distribution which is projected in the direction of the external magnetic field. As a consequence of the periodic pulsing, a nonequilibrium distribution develops as a function of time. The numerical simulation of the coupled dynamics reveals the influence of the hyperfine coupling constant distribution onto the evolution of the electron spin polarization before the next laser pulse. Experimental indications are provided for both subclasses of resonance conditions.

    Spatial health inequalities have often been analysed in terms of deprivation. The aim of this study was to create an ecological deprivation index and evaluate its association with mortality over the entire mainland France territory. More specifically, the variations with the degree of urbanicity, spatial scale, age, gender and cause of death, which influence the association between mortality and deprivation, have been described. The deprivation index, 'FDep99', was developed at the 'commune'(smallest administrative unit in France) level as the first component of a principal component analysis of four socioeconomic variables. Proxies of the Carstairs and Townsend indices were calculated for comparison. The spatial association between FDep99 and mortality was studied using five different spatial scales, and by degree of urbanicity (five urban unit categories), age, gender and cause of death, over the period 1997-2001. 'Avoidable' causes of death were also considered for subjects aged less than 65 years. They were defined as causes related to risk behaviour and primary prevention (alcohol, smoking, accidents). The association between the FDep99 index and mortality was positive and quasi-log-linear, for all geographic scales. The standardized mortality ratio (SMR) was 24% higher for the communes of the most deprived quintile than for those of the least deprived quintile. The between-urban unit category and between-région heterogeneities of the log-linear associations were not statistically significant. The association was positive for all the categories studied and was significantly greater for subjects aged less than 65 years, for men, and for 'avoidable' mortality. The amplitude and regularity of the associations between mortality and the Townsend and Carstairs indices were lower. The deprivation index proposed reflects a major part of spatial socioeconomic heterogeneity, in a homogeneous manner over the whole country. The index may be routinely used by healthcare

    Although subjects with recurrent low back pain (LBP) demonstrate altered postural control, their postural steadiness during one leg standing is unknown. The purpose of this study was to investigate postural steadiness based on relative kinematic index of the lower limbs and trunk with normalized standing time in subjects with recurrent LBP during dominant and non-dominant leg standing. Sixty individuals participated in the study, including 29 subjects in the control group (18 male, 11 female) and 31 subjects with recurrent LBP (21 male, 10 female). The outcome measures included relative kinematic index of the body regions and normalized standing time during the one leg standing test. The relative kinematic index was the ratio between standstill time and successful standing time. The normalized standing time was defined as a ratio between the successful standing time and the requested standing time. The control group demonstrated significantly longer normalized standing time on the dominant (t = -2.57, p = 0.013) and non-dominant (t = -2.78, p = 0.007) legs than the LBP group. The relative kinematic index of the core spine model significantly decreased for the dominant (t = -3.01, p = 0.004) and non-dominant (t = -3.06, p = 0.003) legs in the LBP group. In addition, the kinematic index indicated pelvis and non-dominant shank during dominant leg standing (R 2 = 0.97) in the LBP group. In the control group, the pelvis was significantly correlated with the core spine model during standing on the dominant (R 2 = 0.95) and non-dominant (R 2 = 0.97) legs. The relative kinematic index of the pelvis was found to be most significant for longer standing durations in both groups. In the LBP group, the shank and foot were significantly higher in addition to the pelvis due to possible compensatory motion. The control group took advantage of pelvic control with the core spine to minimize lower limb movements. Clinicians need to consider the core spine for

The aim of this study is to analyze variables influencing holding period of common stock on public firm listed in LQ 45 Index, that are firms generally have good performance assessed based on both market performance and firm fundamental, then analyzing the dominance influencing variable. This study is conducted in Jakarta Stock Exchange with population of stocks listed in LQ 45 index in period of 2000 – 2001 with the total of 64 firms. The Sample Taking Method is purposive sampling with the criteria that the firms at least listed twice in LQ45 index on the study period. The analysis method used to analyze independent variables: spread, market value, variance return, and dividend pay out ratio and dependent variable: holding period is two stage least squares multiple regression model,  since there is possibility that the correlation of bid-ask spread from the current period and bid-ask spread and holding period from the previous period for every stock take place simultaneously. Results of the study showed that, partially, bid-ask spread variable that constitutes the different value between the highest price provided paid by buyer with the lowest price offered by seller has significance positive correlation on holding period of common stock and there is inverse correlation/significance negative between variance return variable that reflect the risk rate from stock effected by fluctuation of stock price and holding period of common stock.

    Abnormal arousal processes, sympathetic influences, as well as wake-like alpha activity during sleep were reported as pathophysiological features of Nightmare Disorder. We hypothesized that in Nightmare Disorder, wake-like cortical activity and peripheral measures linked to arousals would be triggered by physiological processes related to the initiation of REM periods. Therefore, we examined electroencephalographic (EEG), motor and autonomous (cardiac) activity in a group of nightmare (NM) and healthy control (CTL) subjects during sleep-state-transitions while controlling for the confounding effects of trait anxiety. Based on the second-nights' polysomnographic recordings of 19 Nightmare Disordered (NM) and 21 control (CTL) subjects, we examined the absolute power spectra focusing on the alpha range, measures of heart rate variability (HRV) and motor (muscle tone) activity during pre-REM and post-REM periods, separately. According to our results, the NM group exhibited increased alpha power during pre-REM, but not in post-REM, or stable, non-transitory periods. While CTL subjects showed increased HRV during pre-REM periods in contrast to post-REM ones, NM subjects did not exhibit such sleep state-specific differences in HRV, but showed more stable values across the examined sleep stages and less overall variability reflecting generally attenuated parasympathetic activity during sleep-state-transitions and during stable, non-transitory NREM states. These differences were not mediated by waking levels of trait anxiety. Moreover, in both groups, significant differences emerged regarding cortical and motor (muscle tone) activity between pre-REM and post-REM conditions, reflecting the heterogeneity of NREM sleep. Our findings indicate that NM subjects' sleep is compromised during NREM-REM transitions, but relatively stabilized after REM periods. The coexistence of sleep-like and wake-like cortical activity in NM subjects seems to be triggered by REM/WAKE promoting

    Full Text Available BackgroundWe performed a retrospective longitudinal study on the effects of changes in weight, body composition, and homeostasis model assessment (HOMA indices on glycemic progression in subjects without diabetes during a four-year follow-up period in a community cohort without intentional intervention.MethodsFrom 28,440 non-diabetic subjects who participated in a medical check-up program in 2004, data on anthropometric and metabolic parameters were obtained after four years in 2008. Body composition analyses were performed with a bioelectrical impedance analyzer. Skeletal muscle index (SMI, % was calculated with lean mass/weight×100. Subjects were divided into three groups according to weight change status in four years: weight loss (≤-5.0%, stable weight (-5.0 to 5.0%, weight gain (≥5.0%. Progressors were defined as the subjects who progressed to impaired fasting glucose or diabetes.ResultsProgressors showed worse baseline metabolic profiles compared with non-progressors. In logistic regression analyses, the increase in changes of HOMA-insulin resistance (HOMA-IR in four years presented higher odds ratios for glycemic progression compared with other changes during that period. Among the components of body composition, a change in waist-hip ratio was the strongest predictor, and SMI change in four years was a significant negative predictor for glycemic progression. Changes in HOMA β-cell function in four years was a negative predictor for glycemic progression.ConclusionIncreased interval changes in HOMA-IR, weight gain and waist-hip ratio was associated with glycemic progression during a four-year period without intentional intervention in non-diabetic Korean subjects.

    Full Text Available The stochastic resonance (SR characteristics of a generalized Langevin linear system driven by a multiplicative noise and a periodically modulated noise are studied (the two noises are correlated. In this paper, we consider a generalized Langevin equation (GLE driven by an internal noise with long-memory and long-range dependence, such as fractional Gaussian noise (fGn and Mittag-Leffler noise (M-Ln. Such a model is appropriate to characterize the chemical and biological solutions as well as to some nanotechnological devices. An exact analytic expression of the output amplitude is obtained. Based on it, some characteristic features of stochastic resonance phenomenon are revealed. On the other hand, by the use of the exact expression, we obtain the phase diagram for the resonant behaviors of the output amplitude versus noise intensity under different values of system parameters. These useful results presented in this paper can give the theoretical basis for practical use and control of the SR phenomenon of this mathematical model in future works.

    Head-down tilting of primates (HOT) is a universal method of studying the hypokinetic syndrome effects on functionality of various body systems. Clinical biochemical blood assay was performed in a 25-day HDT experiment (-5 degrees) with 11 Macaca rhesus. One group of animals was kept tilted all the time through, whereas the other was periodically returned into the orthostatic position for 30 to 120 minutes 4-5 times a week. Dry chemistry was employed in biochemical analysis of blood serum and enzyme immunodetection (EID) in measuring blood hormones. As a rule, the biochemical parameters of primates' serum were within the physiological norm range. Shifts in protein, carbohydrate and mineral metabolism were sought for and enzymic activity in blood serum and hormone concentrations were determined. HDT did not produce noteworthy changes in blood concentrations of somatotropic hormone, thyrotrophic hormone (TTH), triiodothyronine (T3), thyroxine (T4) or cortisol. Animals of both groups showed statistically reliable decrease in blood osteocalcine. The preventive complex did not contribute materially to the control of metabolic homeostasis and endocrine function of the primates adapting to the 25-day HDT.

    The US federal government initiated the Open Government Directive where federal agencies are required to publish high value datasets so that they are available to the public. Data.gov and the community site Healthdata.gov were initiated to disperse such datasets. However, data searches and retrieval for these sites are keyword driven and severely limited in performance. The purpose of this paper is to address the issue of extracting relevant open-source data by proposing a method of adopting the MeSH framework for indexing and data retrieval. A pilot study was conducted to compare the performance of traditional keywords to MeSH terms for retrieving relevant open-source datasets related to "mortality". The MeSH framework resulted in greater sensitivity with comparable specificity to the keyword search. MeSH showed promise as a method for indexing and retrieving data, yet future research should conduct a larger scale evaluation of the performance of the MeSH framework for retrieving relevant open-source healthcare datasets.

    The aim of this study was to investigate the association between physical activity (PA) and objective heart rate variability (HRV)-based stress and recovery with subjective stress in a longitudinal setting. Working-age participants (n = 221; 185 women, 36 men) were overweight (body mass index, 25.3-40.1 kg/m(2) ) and psychologically distressed (≥3/12 points on the General Health Questionnaire). Objective stress and recovery were based on HRV recordings over 1-3 work days. Subjective stress was assessed with the Perceived Stress Scale and PA level with a questionnaire. Data were collected at three time points: baseline, 10 weeks post intervention, and at the 36-week follow-up. We adopted a latent growth model to investigate the initial level and change in PA, objective stress and recovery, and subjective stress at the three measurement time points. The results showed that initial levels of PA (P stress (P = 0.001) and recovery (P stress. The results persisted after adjustment for intervention group. The present results suggest that high PA and objectively assessed low stress and good recovery have positive effects on changes in subjective stress in the long-term. © 2016 John Wiley & Sons A/S.

    The objective of this study is to investigate the association of body mass index (BMI) with arterial stiffness assessed by cardioankle vascular index (CAVI). A retrospective cross-sectional study was conducted in 23,257 healthy Japanese subjects (12,729 men and 10,528 women, aged 47.1 ± 12.5 years, BMI 22.9 ± 3.4 kg/m(2)) who underwent health screening between 2004 and 2006 in Japan. Exclusion criteria were current medication use and a past history of cardiovascular disease, hypertension, stroke, diabetes, and nephritis. Male subjects showed significantly higher BMI, CAVI, and triglycerides and lower high-density lipoprotein (HDL)-cholesterol compared with female subjects. Next, the subjects were divided into tertiles of BMI: lower, middle, and upper, in a gender-specific manner. After adjusting for confounders including age, systolic blood pressure, and HDL-cholesterol identified by multiple regression analysis, the mean CAVI decreased progressively as BMI tertile increased in both genders. Furthermore, a negative inverse relationship between BMI and adjusted CAVI was observed throughout the BMI distribution. Multivariate logistic regression model for contributors of high CAVI (≥90th percentile) identified obesity (odds ratios (95% confidence interval): 0.804 (0.720-0.899)], older age [15.6 (14.0-17.4)], male gender [2.26 (2.03-2.51)], hypertension [2.28 (2.06-2.54)], impaired fasting glucose [1.17 (1.01-1.37)], and low HDL-cholesterol [0.843 (0.669-1.06)] as independent factors. We demonstrated an inverse relationship between CAVI and BMI in healthy Japanese subjects, suggesting that systemic accumulation of adipose tissue per se may lead to a linear decrease of arterial stiffness in nonobese and obese subjects without metabolic disorders.

    Glucose variability could be an independent risk factor for diabetes complications in addition to average glucose. The deficiency in islet β cell secretion and insulin sensitivity, the two important pathophysiological mechanisms of diabetes, are responsible for glycemic disorders. The oral disposition index evaluated by product of insulin secretion and sensitivity is a useful marker of islet β cell function. The aim of the study is to investigate glycemic variability in relation to oral disposition index in the subjects across a range of glucose tolerance from the normal to overt type 2 diabetes. 75-g oral glucose tolerance test (OGTT) was performed in total 220 subjects: 47 with normal glucose regulation (NGR), 52 with impaired glucose metabolism (IGM, 8 with isolated impaired fasting glucose [IFG], 18 with isolated impaired glucose tolerance [IGT] and 26 with combined IFG and IGT), 61 screen-diagnosed diabetes by isolated 2-h glucose (DM2h) and 60 newly diagnosed diabetes by both fasting and 2-h glucose (DM). Insulin sensitivity index (Matsuda index, ISI), insulin secretion index (ΔI30/ΔG30), and integrated β cell function measured by the oral disposition index (ΔI30/ΔG30 multiplied by the ISI) were derived from OGTT. All subjects were monitored using the continuous glucose monitoring system for consecutive 72 hours. The multiple parameters of glycemic variability included the standard deviation of blood glucose (SD), mean of blood glucose (MBG), high blood glucose index (HBGI), continuous overlapping net glycemic action calculated every 1 h (CONGA1), mean of daily differences (MODD) and mean amplitude of glycemic excursions (MAGE). From the NGR to IGM to DM2h to DM group, the respective values of SD (mean ± SD) (0.9 ± 0.3, 1.5 ± 0.5, 1.9 ± 0.6 and 2.2 ± 0.6 mmol/), MBG (5.9 ± 0.5, 6.7 ± 0.7, 7.7 ± 1.0 and 8.7 ± 1.5 mmol/L), HGBI [median(Q1-Q3)][0.8(0.2-1.2), 2.0(1.2-3.7), 3.8(2.4-5.6) and 6

    Full Text Available The paper presents a novel pressure sensor based on a silicon nitride (SiNx nanocoated long-period grating (LPG. The high-temperature, radio-frequency plasma-enhanced chemical-vapor-deposited (RF PECVD SiNx nanocoating was applied to tune the sensitivity of the LPG to the external refractive index. The technique allows for deposition of good quality, hard and wear-resistant nanofilms as required for optical sensors. Thanks to the SiNx nanocoating it is possible to overcome a limitation of working in the external-refractive-index range, which for a bare fiber cannot be close to that of the cladding. The nanocoated LPG-based sensing structure we developed is functional in high-refractive-index liquids (nD > 1.46 such as oil or gasoline, with pressure sensitivity as high as when water is used as a working liquid. The nanocoating developed for this experiment not only has the highest refractive index ever achieved in LPGs (n > 2.2 at λ = 1,550 nm, but is also the thinnest (

    Long period gratings (LPGs) are coated with hafnium oxide using plasma-enhanced atomic layer deposition (PEALD) to increase the sensitivity of these devices to the refractive index of the surrounding medium. PEALD allows deposition at low temperatures which reduces thermal degradation of UV-written LPGs. Depositions targeting three different coating thicknesses are investigated: 30 nm, 50 nm and 70 nm. Coating thickness measurements taken by scanning electron microscopy of the optical fibers confirm deposition of uniform coatings. The performance of the coated LPGs shows that deposition of hafnium oxide on LPGs induces two-step transition behavior of the cladding modes.

    Full Text Available We present mathematical details of the construction of a topological invariant for periodically driven two-dimensional lattice systems with time-reversal symmetry and quasienergy gaps, which was proposed recently by some of us. The invariant is represented by a gap-dependent Z2-valued index that is simply related to the Kane–Mele invariants of quasienergy bands but contains an extra information. As a byproduct, we prove new expressions for the two-dimensional Kane–Mele invariant relating the latter to Wess–Zumino amplitudes and the boundary gauge anomaly.

    To determine the prevalence of malocclusion and need for orthodontic treatment among persons with Down Syndrome (DS). Study participants were 113 persons with DS from the selected community-based rehabilitation center who fulfilled the inclusion and exclusion criteria. Ten occlusal characteristics of the Dental Aesthetic Index (DAI) were measured on study models to determine the degree of malocclusion. A single score represented the dentofacial anomalies, determined the level of severity, and determined the need for orthodontic treatment. Crowding in the anterior maxillary and mandibular arch was the main malocclusion problems among the subjects with DS. Comparison between age group and genders revealed no significant differences in four categories of orthodontic treatment need (P > .05). Most of the subjects with DS (94; 83.2%) had severe and very severe malocclusion, which indicated a desirable and mandatory need for orthodontic treatment.

    This study evaluated the absolute bioavailability of bosutinib and assessed its safety and tolerability after single-dose oral and intravenous administration. In this phase 1 open-label, 2-sequence, 2-period crossover study, healthy, fed subjects aged 18-55 years were randomized to 1 of 2 treatment sequences (n = 7/sequence): oral bosutinib (100 mg × 5) followed by intravenous bosutinib (120 mg in approximately 240 mL over 1 hour), with a ≥14-day washout, or intravenous bosutinib and then oral bosutinib. Results of plasma pharmacokinetics analyses demonstrated that exposure to intravenous bosutinib was 3-fold higher than for oral bosutinib (16.2 and 5.5 ng·h/mL/mg, respectively), and mean terminal half-life was similar (35.5 and 31.7 hours). The ratio of adjusted geometric means (90%CI) for the dose-normalized area under the plasma concentration-time profile (AUC0-∞ /D) was 33.85% (30.65%-37.38%). Most treatment-emergent adverse events (AEs) were mild in severity. Gastrointestinal (GI) AEs occurred in 9 of 13 subjects given oral bosutinib, whereas no subjects given intravenous bosutinib experienced GI AEs, suggesting bosutinib present in the GI tract had an effect. Bosutinib exhibited an absolute bioavailability of 33.85% based on the ratio of AUC0-∞ /D. Both oral and intravenous bosutinib were safe and well tolerated in healthy, fed adult subjects. © 2017, The American College of Clinical Pharmacology.

    Full Text Available Objective. The aims of this study were to (1 assess physical activity and weight status differences and (2 explore the direction and shape of subjective social status (SSS association with physical activity and weight status within four Asian countries. Methods. Cross section data of adult respondents from the nationally representative East Asian Social Survey were used for analyses. Logistic regression stratified by gender was conducted for the first aim, and simple and quadratic logistic regression models were used for the second. Results. SSS was significantly associated with odds of weekly or daily physical activity across all countries and genders, except for South Korean and Japanese females. Quadratic models provided significantly better fit for Chinese males (LR (d.f. = 1 = 6.51, P value <.05 and females (LR (d.f. = 1 = 7.36, P value <.01, South Korean males (LR (d.f. = 1 = 4.40, P value <.05, and Taiwanese females (LR (d.f. = 1 = 4.87, P value <.05. Conclusions. This study provides a comparable cross Asian country measure of moderate-to-vigorous physical activity and new findings that a connection exists between SSS and physical activity. Differences of class distinction help explain the different shaped SSS relationships.

A cohort of 50-year-old voluntary periodic health examination (PHE participants was analyzed 15 years retrospectively. Our aim was to evaluate changes in body mass index (BMI and blood pressure in subjects diagnosed with hypertension and/or diabetes in comparison with healthy controls. Methods Voluntary periodic health examinations (PHE of the citizens have been carried out by the city of Tampere, Finland. Health data, including body mass index (BMI and blood pressure, were recorded every five years, starting at the age of 35 (baseline. A total of 339 subjects from the 50-year-old cohort having hypertension and/or diabetes were chosen to the study group. The control group included 604 subjects from the 50-year-old cohort who had the same follow-up information but were not diagnosed with hypertension and/or diabetes. Results In the study group the mean BMI had increased from 26.1 at baseline to 28.5 at the final 15-year follow-up examination. The corresponding increase in the control group was from 23.8 at baseline to 25.5 at the final follow-up. The difference in change with time between the groups was statistically significant (p = 0.04. On the average, the controls gained 4.9 kilograms, whereas subjects in the study group gained 7.0 kilograms over the 15 years of follow-up. Systolic and diastolic blood pressures were also higher in the study group already at baseline and systolic blood pressure increased with time more in the study group than in the control group (p = 0.004. Conclusions BMI and blood pressure were higher in the study group in comparison with the controls already at baseline at 35 years, and the differences were not favorably changed during the follow-up. Apparently, the effect of PHE had not been as efficient as planned on subjects in the study group, who were already slightly overweight at baseline.

    Full Text Available Abstract Background The purpose of this study was to investigate the biomechanics of the hip, knee and ankle during a progressive resistance cycling protocol in an effort to detect and measure the presence of muscle fatigue. It was hypothesized that knee power output can be used as an indicator of fatigue in order to assess the cycling performance of SCI subjects. Methods Six spinal cord injured subjects (2 incomplete, 4 complete between the ages of twenty and fifty years old and possessing either a complete or incomplete spinal cord injury at or below the fourth cervical vertebra participated in this study. Kinematic data and pedal forces were recorded during cycling at increasing levels of resistance. Ankle, knee and hip power outputs and resultant pedal force were calculated. Ergometer cadence and muscle stimulation intensity were also recorded. Results The main findings of this study were: (a ankle and knee power outputs decreased, whereas hip power output increased with increasing resistance, (b cadence, stimulation intensity and resultant pedal force in that combined order were significant predictors of knee power output and (c knowing the value of these combined predictors at 10 rpm, an index of fatigue can be developed, quantitatively expressing the power capacity of the knee joint with respect to a baseline power level defined as fatigue. Conclusion An index of fatigue was successfully developed, proportionalizing knee power capacity during cycling to a predetermined value of fatigue. The fatigue index value at 0/8th kp, measured 90 seconds into active, unassisted pedaling was 1.6. This indicates initial power capacity at the knee to be 1.6 times greater than fatigue. The fatigue index decreased to 1.1 at 2/8th kp, representing approximately a 30% decrease in the knee's power capacity within a 4 minute timespan. These findings suggest that the present cycling protocol is not sufficient for a rider to gain the benefits of FES and thus

    Despite a significant progress in loading and design codes of seismic resistant structures and technology improvements in building structures, the field of civil engineering is still facing critical challenges. An example of those challenges is the assessment of the state of damage that has been imposed to a structure after earthquakes of different intensities. To determine the operability of a structure and its resistance to probable future earthquakes, quick assessment of damages and determining the operability of a structure after an earthquake are crucial. Present methods to calculate damage to structures are time consuming and do not accurately provide the rate of damage. Damage estimation is important task in the fields of structural health monitoring and decision-making. This study examines the relationship between period elongation and the Park-Ang damage index. A dynamic non-linear analysis is employed with IDARC program to calculate the amount of damage and period of the current state. This new method is shown to be a quick and accurate technique for damage assessment. It is easy to calculate the period of an existing structure and changes in the period which reflects changes in the stiffness matrix.

    To assess the reliability of standing time and the Kinematic Steadiness Index (KSI) in one-leg standing compared with the Timed Up and Go (TUG) test while considering anthropometric factors in subjects with recurrent low back pain (LBP). Sixty-six individuals participated in the study. The data were collected on two different days, 1 week apart. The KSI of the core spine, using video motion-capture techniques, was based on the relative standing time and relative standstill time. The intraclass correlation coefficient (ICC2,1) was compared for the reliability between measures. The covariates, such as age, Body Mass Index, and the Oswestry Disability Index (ODI), were analyzed for any interactions based on these measures. The standing time (t = - 1.01, p = 0.32) and the KSI (t = - 1.70, p = 0.09) were not significantly different between measures. The TUG results were not different between measures (t = 1.01, p = 0.32). The Cronbach's alpha for the standing time was 0.84, for KSI was 0.89, and for TUG was 0.76. The standing time and KSI demonstrated an interaction with age, while the TUG demonstrated an interaction with the ODI score. The KSI during one-leg standing could help to develop a practical tool to justify quantity and quality of balance outcome measures, which identify balance deficits and core spine rehabilitation strategies in subjects with recurrent LBP.

    Full Text Available Equal amounts of carbohydrates from various foodstuffs do not increase blood glucose to the same extent. This study was carried out, therefore, in 1996 at the National Nutrition and Food Technology Research institute in Tehran to determine the glycemic index of split pease, rice (Binam, kidney beans, green peas, “Lavash” bread and broad bean kernels. Diabetic subjects were studied in a clinical trial. The exact amount of cabohydrate in foodstuffs was determined using AOAC. Methods. White bread was used as the reference food. After a 12-hour overnight fast on seven separate days each subject was given the test food in an amount to provide 25 g of carbohydrate. Blood glucose was determined after 0, 60, 120 minutes using orthotouidine method. Glycemi response in each individual was calculated as the area under the 2- hour glucose individual was calculated as the area under the test food glucose curve as a percentage of the mean area under the whith bread glucose curve. Glycemic indices of the test foods were 31± 8.5 for split peas, 42.9±3 for rice, 44±9 for kidney beans, 57±7 for green peas, 69±8.5 for “Lavash” bread, and 96±14 for broad bean kernels .Legumes and rice (Binam can be used efficiently in meal planning for the diabetic subjects.

    Dietary fat composition is known to modulate circulating lipid and lipoprotein levels. Although supplementation with long chain omega-3 polyunsaturated fatty acids (LCn-3PUFA) has been shown to reduce plasma triglyceride levels, the effect of the interactions between LCn-3PUFA and the major dietary fats consumed has not been previously investigated. In a randomized controlled parallel design clinical intervention, we examined the effect of diets rich in either saturated fatty acids (SFA) or omega-6 polyunsaturated fatty acids (n-6PUFA) on plasma lipid levels and lipoprotein profiles (lipoprotein size, concentration and distribution in subclasses) in subjects with an adequate omega 3 index. Twenty six healthy subjects went through a four-week pre-supplementation period with LCn-3PUFA and were then randomized to diets rich in either n-6PUFA or SFA both supplemented with LCn-3PUFA. The diet rich in n-6PUFA decreased low density lipoprotein (LDL) particle concentration (-8%, p=0.013) and LDL cholesterol (LDL-C) level (-8%, p=0.021), while the saturated fat rich diet did not affect LDL particle concentration or LDL-C levels significantly. Nevertheless, dietary saturated fatty acids increased LCn-3PUFA in plasma and tissue lipids compared with n-6PUFA, potentially reducing other cardiovascular risk factors such as inflammation and clotting tendency. Improvement on the omega 3 index of healthy subjects did not alter the known effects of dietary saturated fats and n-6PUFA on LDL profiles. Copyright © 2016 Elsevier Inc. All rights reserved.

    2017-04-01

    This work presents combined long-period grating (LPG) and a micro-cavity in-line Mach-Zehnder interferometer (μIMZI), both induced in the same single-mode optical fiber. In order to increase refractive index (RI) sensitivity of the LPG, it has been nanocoated with aluminum oxide (Al2O3). Next, the μIMZI has been fabricated as a cylindrical cavity (d = 60 μm) in the center of the LPG. In transmission measurements for various RI in the cavity and around the LPG we have observed two effects coming from two independently working sensors. There was no significant impact on one or the other in terms of their functional properties. Such a combination of sensorial effects can be applied for cross-reference measurements of the two different parameters at the same time or for discrimination of influence of other parameters on the RI measurements.

    A novel single-ended reflecting long period fiber grating (LPFG) sensor with thin metal film overlay and the sensing system is described. An all-fiber reflection based surface plasma resonance (SPR) LPFG sensor with three-layer structure (core, cladding and metal) is established experimentally and fabricated with a pulsed CO2 laser writing system and vacuum evaporation coating system. Different nm-thick thin metal films are deposited on the reflected LPFG sensor for the excitation of surface plasma waves (SPWs) and the characteristics of the reflection resonance spectra of the LPFG sensor for measuring refractive index of fluids are studied. It is found that different thicknesses of different metal films show different measuring sensitivity. Through the comparison of the resonance wavelength obtained in air, water, alcohol, glycerin and their mixture solution, different sensitivities of the reflected SPR-LPFG sensor have been achieved. The proposed SPR-LPFG sensing scheme offers an efficient platform for achieving high performance fiber sensors for the measurement of ambient refractive index.

    The Acoustic Voice Quality Index (AVQI) is a relatively new clinical method to quantify dysphonia severity. Since it partially relies on continuous speech, its performance may vary with voice-related phonetic differences and thus across languages. The present investigation therefore assessed the AVQI's performance in English, Dutch, German, and French. Fifty subjects were recorded reading sentences in the four languages, as well as producing a sustained vowel. These recordings were later edited to calculate the AVQI. The samples were also perceptually rated on overall dysphonia severity by three experienced voice clinicians. The AVQI's cross-linguistic concurrent validity and diagnostic precision were assessed. The results support earlier data, and confirm good cross-linguistic validity and diagnostic accuracy. Although no statistical differences were observed between languages, the AVQI performed better in English and German and less well in French. These results validate the AVQI as a potentially robust and objective dysphonia severity measure across languages.

    Several single nucleotide polymorphisms (SNPs) have been identified in the beta(2)-adrenergic receptor gene (ADRB2). By the use of five SNPs (G46A, C79G, C491T, C523A, G1053C) for identification of ADRB2 haplotypes in 814 Danish Caucasians, we investigated whether ADRB2 haplotypes are associated...... with body mass index (BMI). The SNPs showed organization into 13 distinct haplotypes and 41 haplotype pairs. The study identified four common haplotypes: ACCCC (10.1 +/- 0.3 %), ACCCG (27.9 +/- 0.3 %), GCCAC (10.8 +/- 0.1 %) and GGCCG (41.0 +/- 0.2 %) (frequencies (SD), seen in 91 % of the population....... In the total population (mean age +/- SD: 50 +/- 16 years), BMI was not related to haplotype pairs, individual SNPs or allelic haplotypes. However, in subjects haplotype groups (p = 0.014) but were not related...

    The ability to monitor arterial blood pressure continuously with unobtrusive body worn sensors may provide a unique and potentially valuable assessment of a patient's cardiovascular health. Pulse wave velocity (PWV) offers an attractive method to continuously monitoring blood pressure. However, PWV technologies based on timing measurements between the ECG and a distal PPG suffer from inaccuracies on mobile patients due to the confounding influence of pre-ejection period (PEP). In this paper, we presented a wearable, continuous blood pressure monitor (ViSi Mobile) that can measure and track changes in PEP. PEP is determined from precordial vibrations captured by an accelerometer coupled to the patient's sternum. The performance of the PEP measurements was evaluated on test subjects with postural change and patient activity. Results showed potential to improve cNIBP accuracy in active patients.

    Previous studies have shown that grounding produces quantifiable physiologic changes. This study was set up to reproduce and expand earlier electrophysiologic and physiologic parameters measured immediately after grounding with improved methodology and state-of-the-art equipment. A multiparameter double-blind experiment was conducted with 14 men and 14 women (age range: 18-80) in relatively good health. Subjects were screened for health problems using a commonly used health questionnaire. They were seated in a comfortable recliner and measured during 2-hour grounding sessions, leaving time for signals to stabilize before, during, and after grounding (40 minutes for each period). Sham 2-hour grounding sessions were also recorded with the same subjects as controls. This report presents results for 5 of the 18 parameters measured. The parameters reported here are: skin conductance (SC), blood oxygenation (BO), respiratory rate (RR), pulse rate (PR), and perfusion index (PI). This study was performed in a rented facility in Encinitas, California. The facility was chosen in a quiet area for its very low electromagnetic noise. For each session, statistical analyses were performed on four 10-minute segments: before and after grounding (sham grounding for control session) and before and after ungrounding (sham ungrounding). There was an immediate decrease in SC at grounding and an immediate increase at ungrounding on all subjects. RR increased during grounding, and the effect lasted after ungrounding. RR variance increased immediately after grounding then decreased. BO variance decreased during grounding, followed by a dramatic increase after ungrounding. PR and PI variances increased toward the end of the grounding period, and this change persisted after ungrounding. These results warrant further research to determine how grounding affects the body. Grounding could become important for relaxation, health maintenance and disease prevention.

    The results of studies evaluating the metabolic effects of glycemic index (GI) in subjects with type 2 diabetes mellitus (DM2) have been contradictory. Consequently, the benefits of its application are controversial and polarized opinions of international organizations have been disclosed. The above situation leads this study to evaluate the acute effect of low and high GI breakfast on the glycemic response and satiety in subjects with DM2 under intensive insulin therapy (IIT). A controlled, crossover and single-blind clinical trial was developed involving 10 obese subjects with DM2 under IIT, with a period of at least six months under IIT and with fast insulin prescription before breakfast. Subjects ingested on two different occasions a high or low GI breakfast. In both stages, glycemia was evaluated at 0 (basal), 30, 60 and 120 min, and satiety and satiation were evaluated through a visual analogue scale. In contrast to high GI breakfast, the low GI meal generated a significant decrease of 46% for the area under the curve of glucose (Δ 1940 mg/dL × 120 min, p = 0.022) and in mean glycemia evaluated at 30, 60 and 120 min. Moreover, in the low GI stage 8 of 10 patients achieved a 2 h postprandial glycemia lower than 180 mg/dL, without statistical significance. A nonsignificant increase of 12.7% (Δ 1.06 cm, p = 0.271) in satiety at 120 min in the low GI stage was observed. In contrast to high GI breakfast, the low GI breakfast generated a significantly lower glycemic response. This assay allowed for the contribution of more in depth nutritional recommendations for this group of patients. Registered under ClinicalTrials.gov Identifier no. NCT02881164.

    To characterize periodic leg movements (PLM) and their association with sleep disturbances in drug-free patients with restless legs syndrome (RLS) and healthy subjects without sleep complaints. Polysomnographic recordings of 95 patients with idiopathic RLS and 31 age-matched controls were compared, and correlation analysis between sleep efficiency and PLM variables was performed. All patients and controls were free of medication for 10 days prior to polysomnography. PLM measures revealed a significantly longer mean duration of single PLM during wakefulness and non rapid eye movement (NREM) sleep in RLS patients as compared to controls. PLM indices were higher in RLS patients than in controls during all sleep stages, but not during wakefulness and slow wave sleep. A significantly higher number of PLM sequences was found in RLS patients than in controls. In RLS patients decreased sleep efficiency was associated with a higher number and a shorter duration of PLM sequences. The mean duration of single PLM might be an appropriate parameter to discriminate between healthy subjects with PLM and patients with RLS. High numbers of PLM sequences of short duration might be an indicator for the decreased sleep quality in RLS patients.

    Full Text Available OBJECTIVE: Independently of total caloric intake, a better quality of the diet (for example, conformity to the Mediterranean diet is associated with lower obesity risk. It is unclear whether a brief dietary assessment tool, instead of full-length comprehensive methods, can also capture this association. In addition to reduced costs, a brief tool has the interesting advantage of allowing immediate feedback to participants in interventional studies. Another relevant question is which individual items of such a brief tool are responsible for this association. We examined these associations using a 14-item tool of adherence to the Mediterranean diet as exposure and body mass index, waist circumference and waist-to-height ratio (WHtR as outcomes. DESIGN: Cross-sectional assessment of all participants in the "PREvención con DIeta MEDiterránea" (PREDIMED trial. SUBJECTS: 7,447 participants (55-80 years, 57% women free of cardiovascular disease, but with either type 2 diabetes or ≥ 3 cardiovascular risk factors. Trained dietitians used both a validated 14-item questionnaire and a full-length validated 137-item food frequency questionnaire to assess dietary habits. Trained nurses measured weight, height and waist circumference. RESULTS: Strong inverse linear associations between the 14-item tool and all adiposity indexes were found. For a two-point increment in the 14-item score, the multivariable-adjusted differences in WHtR were -0.0066 (95% confidence interval, -0.0088 to -0.0049 for women and -0.0059 (-0.0079 to -0.0038 for men.

    To evaluate the inter-examiner reproducibility of Ocular Response Analyzer (ORA) parameters in healthy subjects using the waveform score (WS) for quality control of acquisition. Fifteen healthy subjects had their intraocular pressure (IOP) measured with ORA by 2 masked examiners. An acquisition protocol that aimed at obtaining 4 reliable measurements in each eye with WS≥6 and with as few repeated measurements as possible was employed, whereas a maximum of 8 measurements per eye was allowed. Additional good quality criteria included symmetrical force-in and force-out applanation signal peaks on the ORA waveform and few or no distortions of the applanation signal curve. Only the right eyes were included in the analysis. Examiners were trained but not experienced. The inter-examiner reproducibility of ORA parameters was assessed using the intraclass correlation coefficient (ICC). Mean values of the best 4 measurements were considered in analysis. ICC including the best 4 measurements per eye was high for all ORA parameters. Specifically, ICC for Goldmann-correlated IOP was 0.961, for corneal-compensated IOP was 0.962, for corneal resistance factor was 0.987, and for corneal hysteresis was 0.988. Similar reproducibility was found when only the 3 best measurements per eye were included in the analysis. The protocol for IOP measurement with ORA using the WS ≥6 as quality index achieved high inter-examiner reproducibility for all ORA parameters. High reproducibility was obtained even by inexperienced examiners when considering the mean of the best 3 measurements per eye.

    Full Text Available The association between body mass index (BMI and mortality is not conclusive, especially in East Asian populations. Furthermore, the association has been neither supported by recent data, nor assessed after controlling for weight changes.We evaluated the relationship between BMI and all-cause or cause-specific mortality, using prospective cohort data by the National Health Insurance Service in Korea, which consisted of more than one million subjects. A total of 153,484 Korean adults over 30 years of age without pre-existing cardiovascular disease or cancer at baseline were followed-up until 2010 (mean follow-up period = 7.91 ± 0.59 years. Study subjects repeatedly measured body weight 3.99 times, on average.During follow-up, 3,937 total deaths occurred; 557 deaths from cardiovascular disease, and 1,224 from cancer. In multiple-adjusted analyses, U-shaped associations were found between BMI and mortality from any cause, cardiovascular disease, and cancer after adjustment for age, sex, smoking status, alcohol consumption, physical activity, socioeconomic status, and weight change. Subjects with a BMI < 23 kg/m2 and ≥ 30 kg/m2 had higher risks of all-cause and cause-specific mortality compared with the reference group (BMI 23-24.9 kg/m2. The lowest risk of all-cause mortality was observed in subjects with a BMI of 25-26.4 kg/m2 (adjusted hazard ratio [HR] 0.86; 95% CI 0.77 to 0.97. In subgroup analyses, including the elderly and those with chronic diseases (diabetes mellitus, hypertension, and chronic kidney disease, subjects with a BMI of 25-29.9 kg/m2 (moderate obesity had a lower risk of mortality compared with the reference. However, this association has been attenuated in younger individuals, in those with higher socioeconomic status, and those without chronic diseases.Moderate obesity was associated more strongly with a lower risk of mortality than with normal, underweight, and overweight groups in the general population of South Korea

    Full Text Available Infrared false target is an important mean to induce the infrared-guided weapons, and the key issue is how to keep the surface temperature of the infrared false target to be the same as that of the object to be protected. One-dimensional heat transfer models of a metal plate and imitative material were established to explore the influences of the thermophysical properties of imitative material on the surface temperature difference (STD between the metal plate and imitative material which were subjected to periodical ambient conditions. It is elucidated that the STD is determined by the imitative material's dimensionless thickness (dim* and the thermal inertia (Pim. When dim* is above 1.0, the STD is invariable as long as Pim is a constant. And if the dimensionless thickness of metal plate (dm* is also larger than 1.0, the STD approaches to zero as long as Pim is the same as the thermal inertia of metal plate (Pm. When dim* is between 0.08 and 1, the STD varies irregularly with Pim and dim*. However, if dm* is also in the range of 0.08–1, the STD approaches to zero on condition that Pim=Pm and dim*=dm*. If dim* is below 0.08, the STD is unchanged when Pimdim* is a constant. And if dm* is also less than 0.08, the STD approaches to zero as long as Pimdim*=Pmdm*. Furthermore, an application-oriented discussion indicates that the imitative material can be both light and thin via the application of the phase change material with a preset STD because of its high specific heat capacity during the phase transition process.

    The behavior Of Rutherford-type cables under a time-dependent magnetic field is studied. Existing models are extended describing the currents flowing through the resistive contacts at the crossovers between the cable strands by considering crossover current distributions which are not uniform along the cable axis. The generalized system of equations are applied to a few cases of practical interest and show that, if not uniform, the crossover current distribution is periodic, with a period equal to the cable pitch length.

    osteoarthritis according to the ACR criteria. Three dimensional gait analysis was performed. Subjects walked barefoot at self-selected walking speed. The first peak magnitude KI from all three planes were calculated using inverse dynamics. Results Frontal plane kinematics contributed with 59.3% (SD 25.6) of KI...... while sagittal plane kinematics contributed with 40.5% (SD 26.1). A substantial inter-subject variation in the relative contribution of the flexion and extension moment components to KI was observed. Conclusion Our findings support the notion that the primary contributor to KI is the frontal plane...... kinematics (i.e. the knee adduction moment), and secondarily the sagittal plane kinematics (i.e. the knee flexion moment). This holds promise for using KI in clinical trials since both frontal and sagittal knee joint moments have been suggested to be associated with the knee osteoarthritis disease...

    Full Text Available The stochastic behavior of the phase synchronization index (SI and cross-frequency couplings on different days during a hospital stay of three epileptic patients was studied for noninvasive localization of the epileptogenic areas from high density, 256-channel, scalp EEG (dEEG recordings. The study was performed with short-duration (0-180 sec, seizure-free, epileptiform-free and spike-free interictal dEEG data on different days of three subjects. The seizure areas were localized with subdural recordings with an 8×8 macro-electrode grid array and strip electrodes. The study was performed in theta (3-7 Hz, alpha (7-12 Hz, beta (12-30 Hz and low gamma (30-50 Hz bands. A detrended fluctuation analysis was used to find the long range temporal correlations in the SI that reveals the stochastic behavior of the SI in a given time period. The phase synchronization was computed after taking Hilbert transform of the EEG data. Contour plots were constructed with 20 sec time-frames using a montage of the layout of 256 electrode positions. It was found that the stochastic behavior of the SI was higher in epileptogenic areas and in nearby areas on different days for each subject. The low gamma band was found to be the best to localize the epileptic sites. Also, a stable higher pattern of SI emerged after 60-120 seconds in the epileptogenic areas. The cross-frequency couplings of SI in theta-gamma, beta-gamma and alpha-gamma bands were decreased and spatial patterns were fragmented in epileptogenic areas. Combinations of an increase in the stochastic behavior of the SI and decrease in cross-frequency couplings are potential markers to assist in localizing epileptogenic areas. These findings suggest that it is possible to localize the epileptogenic areas noninvasively from a short-duration (~ 180 sec, seizure-free and spike-free interictal scalp dEEG recordings.

    Although ambulatory measurements of heart rate variability (HRV) are widely used, the reproducibility and seasonal variation of ambulatory sampled short-term HRV measurements in healthy participants has not been investigated before. In the present study we collected ambulatory ECGs from 19 healthy participants monthly for 12 months, and for a sub-group of 12 participants weekly for one month. Frequency-domain HRV-metrics were calculated for 5 min ECG segments during (i) a 15-min self-selected rest period (awake period), and (ii) a 30-min sleep period starting 45 min after estimated sleep onset. Total, within- and between-subject coefficient of variation (CV) and seasonal variation were estimated for ln (TP), ln (LFP), ln (HFP), ln (LF/HF), LFnu, HFnu, the mean heart period and the ECG derived respiratory frequency.The within- and between-subject CV varied considerably between different variables, from 100% for ln (LF/HF). Within- and between-subject CV of ln (HFP), LFnu and HFnu were 10-40%. A weak, but significant, seasonal variation was found for ln (TP) (p = 0.05), ln (LFP) (p<0.05) and the respiratory frequency (p<0.01), but the seasonal variation did not affect the within-subject CV. Furthermore, sample size calculations demonstrated that the reproducibility was sufficient for ambulatory HRV measurements to be used to study autonomic cardiac regulation in healthy populations.

  15. Quantum systems subjected to periodic and quasiperiodic external fields; Sistemas quanticos sujeitos a campos externos periodicos e quaseperiodicos

    1996-12-31

    We have study three quantum systems under time dependent external fields. The first one is an harmonic oscillator and the external field is quasiperiodic. We prove that the autocorrelation spectrum is absolutely transient continuous covering the real line on the resonant case or pure point under supplementary diophantine conditions. The second one refers to the spin tunneling. We show that an external periodic field may causes a blocking of spin tunneling. The last problem concerns to the resonances of the Floquet spectrum on the non-perturbative region of parameters for the model of an atom with one bound state under an external periodic field. The problems of Quantum Chaology and Quantum Stability are the predominant points of view in this work. (author) 59 refs., 15 figs., 6 tabs.

    In this work, we use a set of recent multiyear simulations to develop a simplified sea surface height index (SSH). The index characterizes the dynamics of Ionian upper layer circulation and its links with sea surface height and salinity in the Southern Adriatic and Aegean Seas during the period 1987-2008. The analysis highlights a covariant behavior between Ionian Sea and Aegean Sea associated with a mutual zonal exchange of water masses with different salinity characteristics. Our analysis confirms that the variability observed in the period 1987-2008 in the upper layer circulation of the Ionian was driven by the salinity variability in the Southern Adriatic and Aegean Sea. This study supports and reinforces the hypothesis that two observed BiOS-like reversals reflect the existence of multiple equilibrium states in the Mediterranean Thermohaline circulation in the Eastern Mediterranean and that a complete characterization of observed variability needs to take into account a fully coupled Adriatic-Ionian-Aegean System.

  17. “Wildness” as a metaphor for self-definition of the colonised subject in the Positivist period in Poland

    Directory of Open Access Journals (Sweden)

    Anna Kołos

    2011-06-01

    Full Text Available This article discusses the question of the Polish nation's self-definition in the Positivist period both in belles-lettres and in journalism, which were dependent to a great extent on the colonial discourse. It is argued that crucial metaphors of “wildness,” “savageness” or “backwardness” stem from orientalising labels created by the colonisers. Examination of this issue requires some basic introduction to historical and anthropological ideas which date back to the Age of Enlightenment. The aim of this paper is to shed light – by analysing literature examples such as Ludwik Powidaj, Cyprian Kamil Norwid, Maria Konopnicka, Eliza Orzeszkowa and Henryk Sienkiewicz – on the so called “colonial trauma” that has condemned the Polish image to resentful ideology. Furthermore, the paper will provide arguments in favour of subscribing to the postcolonial studies in Central and Eastern Europe.

    Acoustic pharyngometry is a relatively new noninvasive method that quantifies geometrically complexed pharyngeal dimensions. Our study aimed to investigate the predictability and usefulness of acoustic pharyngometry in diagnosis of obstructive sleep apnea (OSA), and we developed a prospective clinical trial in 16 subjects without apnea and 54 subjects with apnea. All seventy subjects received polysomnography (PSG) to assess the sleep architecture, including breathing and the degree of apnea hypopnea index. Acoustic pharyngometry was performed in four body positions (sitting, supine, right and left lateral) while awake with tidal breathing in addition to morphometric measurements (Kushida index) of oral cavity. This study shows that the cross-sectional area and volume of the upper airway is smaller in the supine position than any other positions. As well, the oropharyngeal junction area of the supine position is the most predictive parameter to discriminate between subjects with or without OSA. Acoustic pharyngometry can be a clinically useful tool for localizing the narrowed portion of the upper airway and predicting obstructive sleep apnea. PMID:15483340

    Extended nap opportunities have been effective in maintaining alertness in the context of extended night shifts (+12 h). However, there is limited evidence of their efficacy during 8-h shifts. Thus, this study explored the effects of extended naps on cognitive, physiological and perceptual responses during four simulated, 8-h night shifts. In a laboratory setting, 32 participants were allocated to one of three conditions. All participants completed four consecutive, 8-h night shifts, with the arrangements differing by condition. The fixed night condition worked from 22h00 to 06h00, while the nap early group worked from 20h00 to 08h00 and napped between 00h00 and 03h20. The nap late group worked from 00h00 to 12h00 and napped between 04h00 and 07h20. Nap length was limited to 3 hours and 20 minutes. Participants performed a simple beading task during each shift, while also completing six to eight test batteries roughly every 2 h. During each shift, six test batteries were completed, in which the following measures were taken. Performance indicators included beading output, eye accommodation time, choice reaction time, visual vigilance, simple reaction time, processing speed and object recognition, working memory, motor response time and tracking performance. Physiological measures included heart rate and tympanic temperature, whereas subjective sleepiness and reported sleep length and quality while outside the laboratory constituted the self reported measures. Both naps reduced subjective sleepiness but did not alter the circadian and homeostatic-related changes in cognitive and physiological measures, relative to the fixed night condition. Additionally, there was evidence of sleep inertia following each nap, which resulted in transient reductions in certain perceptual cognitive performance measures. The present study suggested that there were some benefits associated with including an extended nap during 8-h night shifts. However, the effects of sleep inertia

    In cochlear implant (CI) recipients with unilateral hearing loss (UHL) and normal hearing (NH) in the contralateral ear, the central auditory system receives signals of different auditory modalities, i.e. electrically via the CI ear as well as acoustically via the NH ear. The present study investigates binaural integration of bimodal stimulation in the central auditory system of 10 CI subjects with UHL by applying a modified version of the Rapidly Alternating Speech Perception (RASP) test to characterise speech recognition ability under monotic and dichotic listening arrangements. Subsequently, the results for each monotic and dichotic test condition were compared to quantify the binaural benefit from CI usage. The study results demonstrate significantly improved speech recognition under dichotic compared to monotic listening conditions, providing evidence that there is binaural integration of acoustically and electrically transmitted speech segments in the central nervous system at brainstem and cortical levels. In contrast to more commonly used tests of binaural integration, such as localisation, the RASP test provides the clinical option to investigate binaural integration involving structures at the cortical level. © 2015 S.

    Soil quality assessment is needed to evaluate the soil conditions and sustainability of soil and crop management properties, and thus requires a systematic approach to select and interpret soil properties to be used as indicators. The aim of this work was to evaluate and compare different indexing methods to assess quality of an undisturbed grassland soil (UN), a degraded pasture soil (GL) and a no tilled soil (NT) with four different A horizon depths (25, 23, 19 and 14 cm) reflecting a diverse erosion. Twenty four soil properties were measured from 0 to10 (1) and 10 to 20 cm. (2) and a minimum data set was chosen by multivariate principal component analysis (PCA) considering all measured soil properties together (A), or according to their classification in physical, chemical or microbiological (B) properties. The measured soil properties involved either inexpensive or not laborious standard protocols, to be used in routine laboratory analysis (simple soil quality index - SSQI), or a more laborious, time consuming and expensive protocols to determine microbial diversity and microbial functionality by methyl ester fatty acids (PLFA) and catabolic response profiles (CRP), respectively (complex soil quality index - CSQI). The selected properties were linearly normalized and integrated by the weight additive method to calculate SSQI A, SSQI B, CSQI A and CSQI B indices. Two microbiological soil quality indices (MSQI) were also calculated: the MSQI 1 only considered microbiological properties according to the procedure used for calculating SQI; the MSQI 2 was calculated by considering microbial carbon biomass (MCB), microbial activity (Resp) and functional diversity determined by CPR (E). The soil quality indices were SSQI A = MCB 1 + Particulate Organic Carbon (POC)1 + Mean Weight Diameter (MWD)1; SSQI B = Saturated hydraulic conductivity (K) 1 + Total Organic Carbon (TOC) 1 + MCB 1; CSQI A = MCB 1 + POC 1 + MWD 1; CSQI B = K 1+ TOC 1+ 0.3 * (MCB 1+ i/a +POC 1) + 0

    Squat-stand maneuvers (SSMs) have been used to improve the coherence of transfer function analysis (TFA) estimates during the assessment of dynamic cerebral autoregulation (dCA). There is a need to understand the influence of peripheral changes resulting from SSMs on cerebral blood flow, which might confound estimates of dCA. 29 healthy subjects underwent recordings at rest (5 min standing) and 15 SSMs (0.05Hz). Heart rate (3-lead ECG), end-tidal CO2 (capnography), blood pressure (Finometer), cerebral blood velocity (CBV, transcranial Doppler, MCA) and the angle of the thigh (tilt sensor) were measured continuously. The response of CBV to SSMs was decomposed into the relative contributions of mean arterial pressure (MAP), resistance area product (RAP) and critical closing pressure (CrCP). Upon squatting, a rise in MAP (83.6 ± 21.1 % contribution) is followed by increased CBV. A dCA response can be detected, determined by adjustments in RAP and CrCP (left hemisphere) with peak contributions of 24.8 ± 12.7 % and 27.4 ± 22.8 %, respectively, at different times during SSMs. No interhemispheric differences were detected. During standing, the contributions of MAP, RAP and CrCP change considerably. The changes of CBV subcomponents during repeated SSMs indicate a complex response of CBVms. to SSMs that can only be partially explained by myogenic mechanis More work is needed to clarify the potential contribution of other co-factors, such as breath-to-breath changes in pCO2, HR, stroke volume and the neurogenic component of dynamic CA.

    In the present era, thesauri as tools in indexing play an effective role in integrating retrieval preventing fragmentation as well as a multiplicity of terminologies and also in providing information content of documents. This study aimed to investigate the keywords of articles indexed in IranMedex in terms of origin, structure and indexing situation and their Compliance with the Persian Medical Thesaurus and Medical Subject Headings (MeSH). This study is an applied research, and a survey has been conducted. Statistical population includes 32,850 Persian articles which are indexed in the IranMedex during the years 1385-1391. 379 cases were selected as sample of the study. Data collection was done using a checklist. In analyzing the findings, the SPSS Software were used. Although there was no significant difference in terms of indexing origin between the proportion of different types of the Persian and English keywords of articles indexed in the IranMedex, the compliance rates of the Persian and English keywords with the Persian medical thesaurus and MeSH were different in different years. In the meantime, the structure of keywords is leaning more towards phrase structure, and a single word structure and the majority of keywords are selected from the titles and abstracts. The authors' familiarity with the thesauri and controlled tools causes homogeneity in assigning keywords and also provides more precise, faster, and easier retrieval of the keywords. It's suggested that a mixture of natural and control languages to be used in this database in order to reach more comprehensive results.

    Lin, Wang; Qiao, Ni

    2008-03-01

    In this note, the periodic and chaotic responses of two single-degree-of-freedom (SDOF) models are investigated and some interesting results obtained. The first model (original model) has been developed by Narayanan and Sekar [Periodic and chaotic responses of an SDOF system with piecewise linear stiffness subjected to combined harmonic and flow induced excitations, Journal of Sound and Vibration 184 (2) (1997) 281-298] and the second one corresponds to a modified system. The original model, involving a one-sided clearance ( y0) between the mass and the linear spring, is subjected to combined harmonic ( F cos ωt) and flow-induced excitations. Narayanan and Sekar (1997) has shown that periodic, quasi-periodic and chaotic motions of this original model may occur in a range of flow velocities for the case: y0=0 and F≠0. In the present work, numerical calculations are carried out for several other important cases of the original system, showing some interesting, and sometimes unexpected results. The modified model, in particular, involving both-sided clearances, is analyzed numerically subsequently. The effect of flow velocity, clearances on the global dynamics of this modified system is discussed finally.

    Arterial stiffness is an independent predictor for vascular diseases. Cardio-ankle vascular index (CAVI) is a new index of arterial stiffness. N-terminal pro-brain natriuretic peptide (NT-proBNP) is a strong prognostic marker in advanced stage of coronary heart disease (CHD). In the present study, we investigated the relationship between CAVI and NT-proBNP in hypertension and CHD subjects. Five hundred one subjects (male/female, 209/292) from Vascular Medicine of Peking University Shougang Hospital were divided into four groups: healthy group (n = 186), hypertension group (n = 159), CHD group (n = 45), and hypertension with CHD group (n = 111). CAVI was measured using VS-1000 apparatus. Our results showed that CAVI was significantly higher in hypertension subjects with CHD than in healthy and hypertension group, respectively (8.42 ± 1.51 vs. 7.77 ± 1.19; 8.42 ± 1.51 vs. 7.92 ± 1.11; both P vascular-related diseases.

    Few studies addressed the relation of visceral adiposity and high-molecular weight (HMW) adiponectin to arterial stiffness. We investigated the impact of visceral adipose tissue (VAT) and HMW adiponectin on cardio-ankle vascular index (CAVI) in asymptomatic Japanese subjects. We studied 487 consecutive subjects (271 men and 216 women) who underwent general health examination between October 2005 and May 2008. The abdominal, visceral, and subcutaneous adipose tissue areas were determined by low-dose x-ray computed tomography. Serum levels of total and HMW adiponectin were measured using the enzyme-linked immunosorbent assay system based on a monoclonal antibody to humans. Cardio-ankle vascular index was positively correlated with VAT area and negatively correlated with HMW adiponectin levels. We also found the positive association of the number of metabolic syndrome components with CAVI in both sexes. A stepwise multiple regression analysis revealed that age, VAT area, serum HMW adiponectin levels, and homeostasis model assessment of insulin resistance were independent determinants of CAVI. Receiver operating characteristic analyses demonstrated that the predictive value of the VAT area for the extent of CAVI (mild: 75th percentile) exceeded that of total or HMW adiponectin levels in both sexes. In conclusion, increased CAVI is associated with both amounts of VAT measured by computed tomography and serum HMW adiponectin levels in asymptomatic Japanese subjects. Receiver operating characteristic analysis indicates that the VAT area is a lot better predictor of arterial stiffness than adiponectin levels.

    A novel approach to calibrate a phase-shift formed in a long-period fiber grating (LPG) is firstly proposed and numerically demonstrated, which is based on the use of either intensity- or wavelength-interrogation technique to the main loss-peak of the phase-shift LPG in the spectrum. Moreover, by using a CO2 laser with high-repetition-rate pulses emission, an equivalent phase-shift is successfully created at middle of the LPG. As an application of the proposed calibration scheme, measurement for the temperature and the refractive index of the ambient solution has been proposed and successfully demonstrated by using a phase-shifted LPG.

    Mental health disorders and suicide are an important and growing public health concern in Korea. Evidence has shown that both globally and in Korea, obesity is associated with an increased risk of developing some psychiatric disorders. Therefore, we examined the association between distorted body weight perception (BWP) and suicidal ideation. Data were obtained from the 2007-2012 Korea National Health and Nutritional Evaluation Survey (KNHANES), an annual cross-sectional nationwide survey that included 14 276 men and 19 428 women. Multiple logistic regression analyses were conducted to investigate the associations between nine BWP categories, which combined body image (BI) and body mass index (BMI) categories, and suicidal ideation. Moreover, the fitness of our models was verified using the Akaike information criterion. Consistent with previous studies, suicidal ideation was associated with marital status, household income, education level, and perceived health status in both genders. Only women were significantly more likely to have distorted BWP; there was no relationship among men. In category B1 (low BMI and normal BI), women (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.48 to 3.42) were more likely to express suicidal ideation than women in category B2 (normal BMI and normal BI) were. Women in overweight BWP category C2 (normal BMI and fat BI) also had an increased OR for suicidal ideation (OR, 2.25; 95% CI, 1.48 to 3.42). Those in normal BWP categories were not likely to have suicidal ideation. Among women in the underweight BWP categories, only the OR for those in category A2 (normal BMI and thin BI) was significant (OR, 1.34; 95% CI, 1.13 to 1.59). Distorted BWP should be considered an important factor in the prevention of suicide and for the improvement of mental health among Korean adults, especially Korean women with distorted BWPs.

Multiple logistic regression analyses were conducted to investigate the associations between nine BWP categories, which combined body image (BI and body mass index (BMI categories, and suicidal ideation. Moreover, the fitness of our models was verified using the Akaike information criterion. Results: Consistent with previous studies, suicidal ideation was associated with marital status, household income, education level, and perceived health status in both genders. Only women were significantly more likely to have distorted BWP; there was no relationship among men. In category B1 (low BMI and normal BI, women (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.48 to 3.42 were more likely to express suicidal ideation than women in category B2 (normal BMI and normal BI were. Women in overweight BWP category C2 (normal BMI and fat BI also had an increased OR for suicidal ideation (OR, 2.25; 95% CI, 1.48 to 3.42. Those in normal BWP categories were not likely to have suicidal ideation. Among women in the underweight BWP categories, only the OR for those in category A2 (normal BMI and thin BI was significant (OR, 1.34; 95% CI, 1.13 to 1.59. Conclusions: Distorted BWP should be considered an important factor in the prevention of suicide and for the improvement of mental health among Korean adults, especially Korean women with distorted BWPs.

    This study evaluated the effect of supervised exercise training on liver enzymes and two surrogate measures of non-alcoholic fatty liver disease (NAFLD) in subjects with type 2 diabetes. Sedentary patients from 22 outpatient diabetes clinics were randomized by center, age and treatment to twice-a-week supervised aerobic and resistance training plus structured exercise counseling (exercise group, EXE; n=303) versus counseling alone (control group, CON; n=303) for 12 months. EXE participants were further randomized to low-to-moderate (n=142) or moderate-to-high (n=161) intensity training of equal energy cost. Baseline and end-of-study levels of liver enzymes, fatty liver index (FLI) and visceral adiposity index (VAI) were obtained. Enzyme levels did not change, whereas FLI and VAI decreased significantly in EXE, but not CON participants. Physical activity (PA) volume was an independent predictor of both FLI and VAI reductions, the extent of which increased from the 1st to the 4th quintile of PA volume and baseline to end-of-study changes in fitness parameters. Differences in the effect of LI versus HI training were negligible. Data from this large cohort of subjects with type 2 diabetes indicate that FLI and VAI decrease with supervised training in a volume-dependent manner. Copyright © 2015 Elsevier Ireland Ltd.

    The purpose of this study was to determine the patterns of lumbopelvic motion and erector spinae (ES) activity during trunk flexion-extension movements and to compare these patterns between patients with recurrent low back pain (LBP) in their pain-free periods and matched asymptomatic subjects. Thirty subjects participated (15 patients with disc herniation and recurrent LBP in their pain-free periods and 15 asymptomatic control subjects). A 3-dimensional videophotogrammetric system and surface electromyography (EMG) were used to record the angular displacements of the lumbar spine and hip in the sagittal plane and the EMG activity of the ES during standardized trunk flexion-extension cycles. Variables were maximum ranges of spine and hip flexion; percentages of maximum lumbar and hip flexion at the start and end of ES relaxation; average percentages of EMG activity during flexion, relaxation, and extension; and flexion-extension ratio of myoelectrical activity. Recurrent LBP patients during their pain-free period showed significantly greater ES activation both in flexion and extension, with a higher flexion-extension ratio than controls. Maximum ranges of lumbar and hip flexion showed no differences between controls and patients, although patients spent less time with their lumbar spine maximally flexed. This study showed that reduced maximum ranges of motion and absence of ES flexion-relaxation phenomenon were not useful to identify LBP patients in the absence of acute pain. However, these patients showed subtle alterations of their lumbopelvic motion and ES activity patterns, which may have important clinical implications.

    Motor Unit Number Index (MUNIX) is a neurophysiological measure that provides an index of the number of lower motor neurons in a muscle. Its performance across centres in healthy subjects and patients with Amyotrophic Lateral Sclerosis (ALS) has been established, but inter-rater variability between multiple raters in one single subject has not been investigated. To assess reliability in a set of 6 muscles in a single subject among 12 examiners (6 experienced with MUNIX, 6 less experienced) and to determine variables associated with variability of measurements. Twelve raters applied MUNIX in six different muscles (abductor pollicis brevis (APB), abductor digiti minimi (ADM), biceps brachii (BB), tibialis anterior (TA), extensor dig. brevis (EDB), abductor hallucis (AH)) twice in one single volunteer on consecutive days. All raters visited at least one training course prior to measurements. Intra- and inter-rater variability as determined by the coefficient of variation (COV) between different raters and their levels of experience with MUNIX were compared. Mean intra-rater COV of MUNIX was 14.0% (±6.4) ranging from 5.8 (APB) to 30.3% (EDB). Mean inter-rater COV was 18.1 (±5.4) ranging from 8.0 (BB) to 31.7 (AH). No significant differences of variability between experienced and less experienced raters were detected. We provide evidence that quality control for neurophysiological methods can be performed with similar standards as in laboratory medicine. Intra- and inter-rater variability of MUNIX is muscle-dependent and mainly below 20%. Experienced neurophysiologists can easily adopt MUNIX and adequate teaching ensures reliable utilization of this method.

    Non-alcoholic fatty liver disease is associated with insulin resistance and dyslipidaemia and can progress to steatohepatitis and cirrhosis. We sought to determine whether dietary fat and saturated fat content alter liver fat in the absence of weight change in an older population. Liver fat was quantified by magnetic resonance spectroscopy before and after 4 weeks on an isoenergetic low-fat/low-saturated fat/low-glycaemic index (LGI) (LSAT: 23 % fat/7 % saturated fat/GI 70) diet in older subjects. In the present study, twenty subjects (seven males/thirteen females; age 69.3 (SEM 1.6) years, BMI 26.9 (SEM 0.8) kg/m2) were randomised to the LSAT diet and fifteen subjects (six males/nine females; age 68.6 (SEM 1.8) years, BMI 28.1 (SEM 0.9) kg/m2) to the HSAT diet. Weight remained stable. Liver fat decreased significantly on the LSAT diet (median 2.2 (interquartile range (IQR) 3.1) to 1.7 (IQR 1.8) %, P= 0.002) but did not change on the HSAT diet (median 1.2 (IQR 4.1) to 1.6 (IQR 3.9) %). The LSAT diet lowered fasting glucose and total cholesterol, HDL-cholesterol and LDL-cholesterol and raised TAG (Pdiet had no effect on glucose or HDL-cholesterol but increased total cholesterol and LDL-cholesterol (Pdiet, but the Matsuda index of insulin sensitivity improved on the LSAT diet (Pdiet was a predictor of changes in lipid parameters but not liver fat. We conclude that diet composition may be an important factor in the accumulation of liver fat, with a low-fat/low-saturated fat/LGI diet being beneficial.

    This study was planned to investigate the normal reference values of myocardial performance index (MPI) obtained by tissue Doppler echocardiography (TDE) and the agreement between MPI measured by TDE and conventional MPI measured by pulsed-wave Doppler (PWD) in healthy subjects and patients with heart failure (HF). Two hundred and three patients with HF and 190 healthy subjects were enrolled in this study. Isovolumic contraction and relaxation time (ICT and IRT) and ejection time (ET) were measured from mitral inflow and left ventricular (LV) outflow. Tissue Doppler echocardiography recordings were obtained at the septal, lateral, inferior, and anterior of the mitral annulus and same time intervals were measured. Myocardial performance index was calculated. The functional capacity of the patients with HF was determined according to New York Heart Association classification. TDE-MPI values were higher than conventional PWD-MPI values in both groups (53%+/-8% vs 48%+/-11%, P<0.0001 in the healthy subjects; 84%+/-21% vs 72%+/-19%, P<0.0001 in the patients with HF). Moderate agreement was found between PWD-MPI and LV mean TDE-MPI in both groups. In identifying patients with moderately or severely decreased LV ejection fraction, TDE-MPI had higher cutoff values than conventional PWD-MPI, and TDE-MPI had higher specificity, sensitivity, negative predictive value, and diagnostic accuracy. In patients with HF, TDE-MPI had a stronger correlation with LV ejection fraction and functional capacity than did PWD-MPI. TDE-MPI is an alternative to conventional PWD-MPI in assessment of cardiac function. However, the higher MPI cutoff points should be considered when this method is used for the evaluation of cardiac function.

    Omega-3-carboxylic acids (OM3-CA) contain omega-3 free fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), as carboxylic acids. Food intake is known to affect the bioavailability of ethyl ester fatty acid formulations. We conducted a phase I study to investigate the effects of the timing of OM3-CA administration relative to food intake on the pharmacokinetics of EPA and DHA. In this randomized, open-label, three-period crossover study, Japanese healthy male subjects were administered 4×1 g OM3-CA capsules with continued fasting, before a meal, or after a meal. All subjects fasted for ≥10 h prior to drug/meal administration. The primary objective was to examine the effect of meal timing on the pharmacokinetics of EPA and DHA after OM3-CA administration. The secondary objectives were to examine the safety and tolerability of OM3-CA. A total of 42 Japanese subjects was enrolled in the study. The baseline-adjusted maximum concentration and area under the concentration-time curve from 0 to 72 h for EPA, DHA, and EPA +DHA were lower in the fasting and before meal conditions than in the after meal condition. The maximum total EPA, total DHA, and total EPA+DHA concentrations were reached later when administered in fasting conditions than in fed conditions, indicating slower absorption in fasting conditions. Diarrhea was reported by five, six, and no subjects in the fasting, before meal, and after meal conditions, respectively. The timing of OM3-CA administration relative to food intake influences the systemic bioavailability of EPA and DHA in healthy Japanese male subjects. NCT02372344.

    Although aging-related elastic arterial stiffness is an independent indicator of cardiovascular risk, the roles of polyunsaturated fatty acids in this condition remain uncertain. This prospective study examined the relationships of aging, persist overweight and plasma fatty acids with arterial stiffening over 3 years. We divided a cohort of 179 healthy, nonhypertensive subjects (aged ≥50 years) into 2 groups: a normal-weight group (18.5 kg/m(2) ≤ body mass index [BMI] < 25 kg/m(2), n = 103) and an overweight group (25 kg/m(2) ≤ BMI< 30 kg/m(2), n = 76). Brachial-ankle pulse wave velocity (ba-PWV) and plasma fatty acids were measured at baseline and after 3 years. After 3 years, the overweight group showed greater increases in systolic and diastolic blood pressure, insulin, homeostasis model assessment-Insulin resistance index and ba-PWV values (P = .009) than the normal-weight group. In addition, greater reductions in eicosapentaenoic acid (C20:3, n-3, EPA; P = .009) and the EPA/arachidonic acid (C20:4, n-6, AA) ratio (P = .001) were found in the overweight group. Multivariate analyses revealed that changes in (Δ) ba-PWV were significantly and positively associated with baseline BMI values and ΔAA/linoleic acid ratios (C18:2, n-6, LA) and negatively associated with ΔEPA/AA ratios. In a subanalysis using baseline BMI values, Δba-PWV correlated strongly and negatively with ΔEPA/AA ratios (r = -0.595, P < .001) and positively with ΔAA/LA ratios (r = 0.455, P < .001) in the overweight group. This study suggests that the persistence of overweight over 3 years in subjects ≥50 years old is associated with faster arterial stiffening than is observed in normal-weight subjects and that this stiffening is independently associated with increases in AA/LA and decreases in EPA/AA ratios.

    The objective of this study was to compare physiological and psychological relaxation by assessing heart rate variability (HRV), prefrontal cortex activity, and subjective indexes while subjects performed a task with and without foliage plants. In a crossover experimental design, 24 university students performed a task transferring pots with and without a foliage plant for 3 min. HRV and oxyhemoglobin (oxy-Hb) concentration in the prefrontal cortex were continuously measured. Immediately thereafter, subjective evaluation of emotions was performed using a modified semantic differential (SD) method and a profile of mood state questionnaire (POMS). Results showed that the natural logarithmic (ln) ratio of low frequency/high frequency, as an estimate of sympathetic nerve activity, was significantly lower while performing the task with foliage plants for the average 3 min measurement interval. Oxy-Hb concentration in the left prefrontal cortex showed a tendency to decrease in the 2-3 min interval in the task with foliage plants compared to the task without plants. Moreover, significant psychological relaxation according to POMS score and SD was demonstrated when the task involved foliage plants. In conclusion, the task involving foliage plants led to more physiological and psychological relaxation compared with the task without foliage plants.

    To evaluate the pharmacokinetics of paroxetine controlledrelease tablets after single oral administrations and its safety profile in healthy Chinese subjects. This was a phase I, openlabel, single-dose, three-period crossover study in which 12 healthy subjects received single oral doses of 12.5, 25, 37.5 mg paroxetine controlled-release tablets with 10-day washout between doses. Serial venous blood samples were collected for 96 hours after study drug administration and analyzed with LC-MS/MS. Pharmacokinetic parameters of paroxetine were calculated using non-compartmental analysis with Win-Nonlin software. The absorption of controlled-release paroxetine was delayed with a median tmax of 8 - 10 hours and the mean t1/2 was 12 - 14 hours across all doses. Over the dose range of 12.5 - 37.5 mg, the mean Cmax increased from 2.62 to 15.13 ng/mL and AUC0-∞ increased from 63.56 to 404.91 h×ng/mL. The 90% CI for the ratio of dose-normalized mean values of Cmax and AUC were not contained within the criteria limits, indicating a greater than doseproportional increase. All reported adverse events were considered to be mild. Plasma exposure of controlled-release paroxetine increased with dose escalation, but linear pharmacokinetics were not observed over the studied doses. Paroxetine controlled-release tablet was well tolerated in healthy Chinese subjects.

    Full Text Available Abstract Background Cardiovascular Magnetic Resonance (CMR enables non-invasive quantification of cardiac output (CO and thereby cardiac index (CI, CO indexed to body surface area. The aim of this study was to establish if CI decreases with age and compare the values to CI for athletes and for patients with congestive heart failure (CHF. Methods CI was measured in 144 healthy volunteers (39 ± 16 years, range 21–81 years, 68 females, in 60 athletes (29 ± 6 years, 30 females and in 157 CHF patients with ejection fraction (EF below 40% (60 ± 13 years, 33 females. CI was calculated using aortic flow by velocity-encoded CMR and is presented as mean ± SD. Flow was validated in vitro using a flow phantom and in 25 subjects with aorta and pulmonary flow measurements. Results There was a slight decrease of CI with age in healthy subjects (8 ml/min/m2 per year, r2 = 0.07, p = 0.001. CI in males (3.2 ± 0.5 l/min/m2 and females (3.1 ± 0.4 l/min/m2 did not differ (p = 0.64. The mean ± SD of CI in healthy subjects in the age range of 20–29 was 3.3 ± 0.4 l/min/m2, in 30–39 years 3.3 ± 0.5 l/min/m2, in 40–49 years 3.1 ± 0.5 l/min/m2, 50–59 years 3.0 ± 0.4 l/min/m2 and >60 years 3.0 ± 0.4 l/min/m2. There was no difference in CI between athletes and age-controlled healthy subjects but HR was lower and indexed SV higher in athletes. CI in CHF patients (2.3 ± 0.6 l/min/m2 was lower compared to the healthy population (p 2 = 0.07, p  Conclusions CI decreases in healthy subjects with age but does not differ between males and females. We found no difference in CI between athletes and healthy subjects at rest but CI was lower in patients with congestive heart failure. The presented values can be used as reference values for flow velocity mapping CMR.

    Although a relationship between post-challenge hyperglycemia and arterial stiffness has been reported, the relationship between the postprandial glucose levels and cardio-ankle vascular index (CAVI) in non-diabetic subjects is not clear. This study thus evaluated the association between the postprandial glucose levels after a composite meal and the degree of arterial stiffness measured according to CAVI in non-diabetic subjects. The subjects included 1,291 individuals (655 men and 636 women; mean age, 48.6 years; range, 23-85 years) who underwent medical examinations, including blood tests and CAVI assessments, between October 2005 and April 2012. The 1-hour postprandial glucose levels were determined after a 600-kcal traditional Japanese meal. The CAVI values were significantly higher in the subjects with higher 1-hour postprandial glucose levels (≥140 mg/dL in men; ≥158 mg/dL in women). A simple regression analysis indicated that the CAVI values were significantly correlated with the 1-hour postprandial glucose levels in men (r=0.286, pblood pressure, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, 1-hour postprandial glucose, homeostatis model assessment of insulin resistance, estimated glemerular filtration rate, and high sensitive C-reactive protein, stepwise multiple regression analysis demonstrated that the 1-hour postprandial glucose level was an independent predictor associated with the CAVI in men (p=0.003) and older women 50 years of age or older (p=0.003). This study demonstrated that the 1-hour postprandial glucose levels are associated with increased CAVI values in non-diabetic men and older women 50 years of age or older.

    There is growing interest in the importance of ensuring that biodiversity conservation is not achieved at the expense of local people’s well-being. It has been suggested that when evaluating the impact of an intervention, the affected population should be allowed to define well-being (requiring...... a subjective measure), and impacts (requiring a participatory approach), but very few, if any, conservation evaluations live up to these standards. We used a participatory impact evaluation approach with the Global Person Generated Index (GPGI) to investigate the relative impacts of strict protection......, and the relative importance of the five identified domains. Participatory impact evaluation establishes local perceptions of the cause-effect relationship between an intervention and respondents’ performance in each domain. Over half the respondents perceived no positive or negative impacts from the conservation...

    2014-01-01

    Full Text Available This paper aims to evaluate the macroeconomic performance of some chosen countries in the period 1997-2012 using the four variables that compose the “magic square” diagram suggested by Nicholas Kaldor (1971. In order to avoid problems with the variables’ scale, the standardized “Index of Economic Welfare” created by René A. Medrano-B and Joanílio R. Teixeira (2013 was utilized. The results showed a good performance of China and the Asian countries. Furthermore, in spite of the impact of the crises of 1998 and 2008 into Russia, this country presented a good recuperation and achieved a high index just after these crises. The Brazilian performance was somewhat surprising. The country showed a low growth rate and a progressive current account deficit, both typical of developed nations, along with a high inflation, typical of developing countries. A positive aspect seems to be the country’s capability of avoiding external crises, like the verified in 2008-2009.

    Prediabetes, defined as impaired fasting glucose (IFG) and impaired glucose tolerance (IGT), likely develops to type 2 diabetes mellitus (DM) and independently increases cardiovascular risk. We employed disposition index (DI), a new metabolic parameter indicating the pancreatic beta cell function adjusted for insulin resistance, and investigated whether it could be altered in Japanese population with prediabetes and associated with early glucose intolerance. A total of 102 adults who underwent an oral glucose tolerance test at the medical screening were designated to normal glucose tolerance (NGT), IFG, IGT, and DM. We calculated insulinogenic index (IGI) and homeostasis model assessment (HOMA) of β cell function (HOMA-β) as insulin secretory function, HOMA-insulin resistance (HOMA-IR), and quantitative insulin sensitivity check index (QUICKI) as insulin resistance and DI, and assessed correlations between these indices and glycemic parameters. We observed graded increase of glycemic parameters in the order of NGT, IFG, IGT, and DM. HOMA-IR was significantly higher only in DM compared with NGT, although HOMA-β, IGI, and QUICKI showed no significant differences among the groups. In contrast, DI was significantly lower in IFG, IGT, and DM compared with NGT. In correlation analysis, glycemic parameters related positively to HOMA-IR, but inversely to DI. Only two parameters, IGI and particularly DI, were significantly decreased in the subjects with 1-hr postload glucose >8.6 mmol/L previously proposed as a predictor of type 2 diabetes. Our results suggest that reduction of DI promptly reflects the alteration of early glucose intolerance in Japanese population presenting with prediabetes.

    The declining or fluctuating trend in blood pressure (BP) despite the rising trend in body mass index (BMI) during childhood and adolescence is unexplained. We decomposed trends in BP and BMI to identify the relevance of early-life and contemporaneous factors. We assessed the relative contribution of age, period and cohort to secular trends in BP in children and adolescents (9-18 years) from 1999 to 2014 and BMI (6-18 years) from 1996 to 2014 in Hong Kong, China. After accounting for age, period effects contributed more than cohort effects to the overall fluctuating BP trend and the rising BMI trend observed in this Chinese population. For both sexes, BP fell from the start of period to a low point in 2003-2005 but then rose. BMI rose strongly across the period before levelling off in 2009-2010. Earlier cohorts (born in 1983-1984) had higher BP and BMI than later cohorts. With globalisation and associated lifestyle changes, successive generations of children and adolescents in a recently developed Chinese setting had lower BP and BMI, but this fall was offset until recently by population-wide increase in BMI. School-based health promotion efforts could have partly mitigated the population-wide rise in child and adolescent BMI, while socioeconomic transition or other factors could be relevant to changes in BP between generations. Explaining these trends will help identify early-life factors that may contribute to a healthier start as well as contemporaneous factors that may protect against rising trends in adiposity. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Essentials Prothrombin complex concentrates (PCCs) may reverse the effect of factor Xa (FXa) inhibitors. We conducted an open-label, randomized, placebo-controlled, three-period crossover study in 15 subjects. Both PCCs rapidly reversed apixaban-mediated decreases in mean endogenous thrombin potential. Four-factor PCC administration had no effect on apixaban pharmacokinetics or anti-FXa activity. Background Currently, there is no approved reversal agent for direct activated factor Xa (FXa) inhibitors; however, several agents are under investigation, including prothrombin complex concentrates (PCCs). Objective This open-label, randomized, placebo-controlled, three-period crossover study assessed the effect of two four-factor PCCs on apixaban pharmacodynamics and pharmacokinetics in 15 healthy subjects. Methods Subjects received apixaban 10 mg twice daily for 3 days. On day 4, 3 h after apixaban, subjects received a 30-min infusion of 50 IU kg-1 Cofact, Beriplex P/N (Beriplex), or saline. Change in endogenous thrombin potential (ETP), measured with a thrombin generation assay (TGA), was the primary endpoint. Secondary endpoints included changes in other TGA parameters, prothrombin time (PT), International Normalized Ratio (INR), activated partial thromboplastin time, anti-FXa activity, apixaban pharmacokinetics, and safety. Results Apixaban-related changes in ETP and several other pharmacodynamic measures occurred following apixaban administration. Both PCCs reversed apixaban's effect on ETP; the differences in adjusted mean change from pre-PCC baseline to end of infusion were 425 nm min (95% confidence interval [CI] 219.8-630.7 nm min; P 0.05) for Beriplex. Both PCCs returned ETP to pre-apixaban baseline levels 4 h after PCC infusion, versus 45 h for placebo. For both PCCs, mean ETP peaked 21 h after PCC initiation, and then slowly decreased over the following 48 h. Both PCCs reversed apixaban's effect on TGA peak height, PT, and INR.

    Mediterranean sediments are valuable archives of both African monsoon variability and higher-latitude climate processes, and can also be used to provide an environmental context for early human migrations and settlements. However, the long history of Mediterranean palaeoclimate studies largely pre-dates the advent of widespread x-ray fluorescence (XRF) core-scanning, so there are few continuous and high-resolution geochemical records from this key region that extend beyond the last glacial cycle. Here we present XRF core-scanning results for ODP Site 967 (Eastern Mediterranean) that have been fully-calibrated into element concentrations spanning the last 3 million years (My). Comparison with independent geochemical data from conventional XRF highlights disparities for certain element/element ratios, thus suggesting the need for caution when taking ratios of scanning XRF data. Principal component analysis of the calibrated XRF dataset reveals two dominant components: detrital inputs (PC1) and a 'sapropel' (≈monsoon run-off) signal (PC2), which we use to establish a new orbitally-tuned chronology. We observe inverse covariation between PC2 and a previously published aeolian dust record from ODP Site 967 (Larrasoaña et al., 2003), and combine these records to produce a composite index of humidity and aridity for the wider North African region over the past 3 My. We propose that by combining run-off and dust signals in a single metric, our index captures the effects of both strengthening/northward migration (increased run-off) and weakening/southward retreat (increased dust) of the North African monsoon. Comparison of the index with published records of Northwest and East African palaeohumidity suggests that it tracks the timing of ;Green Sahara Periods; throughout the Plio-Pleistocene, and that at least 30 of these intervals coincided with increased humidity across East Africa. We tentatively suggest that these specific episodes may be termed ;pan-African Humid

    Ambulatory Arterial Stiffness Index (AASI) has been proposed as an indirect and simpler method to estimate the Arterial Stiffness (AS). AASI, calculated from a set of data collected during a 24-hours ambulatory blood pressure monitoring (ABPM), is defined as 1 minus the regression slope of diastolic on systolic blood pressure (BP) values. For a given increase in diastolic BP, the increase in systolic BP is smaller in a compliant compared to a stiff artery; the stiffer the arterial tree, the closer AASI is to 1. AASI was demonstrated to predict cardiovascular mortality, cerebrovascular events and to be associated with target organ damage. Taking into account the almost complete absence of data regarding the ability of AASI to predict the different degree of AS when hypertensives are divided into four classes of dipping in relation to the extent of the nocturnal reduction of BP (extreme dippers, dippers, mild dippers and reverse dippers) aim to clarify the ability of AASI to estimate the different degree of AS of hypertensive subjects with different nocturnal BP profile and resulting in different extent of organ damage. We enrolled 816 subjects (403 men and 413 women) with essential hypertension, referred to the U.O.C of Medicina Interna e Cardioangiologia of the University of Palermo; 173 subjects (71 men and 102 women, mean age 44.4 ± 14.6 years) without a history of hypertension were enrolled as controls. The analysis of data was performed by dividing the population into four categories in relation to the extent of the nocturnal decline of BP: 124 extreme dipper (mean age 54,8 ± 12,4 years, men 46.8 %); 287 dipper (mean age 55,9 ± 14,2 years, men 54,0 %); 271 mild dipper (mean age 61,5 ± 14,7 years, men 52,0 %); 134 reverse dipper (mean age 61,5 ± 14,7 years, men 33.6 %). The mean value of AASI was significantly higher for mild and reverse dippers versus control patients and versus the other categories of dipping. The multiple regression analysis with AASI as

    To evaluate the responsiveness and minimal important changes (MICs) for the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and its subscales in subjects with hip fractures. At the beginning and end of a 2-month rehabilitation program, 106 patients completed the WOMAC. After the program, the global perceived effect (GPE) was analyzed to produce a dichotomous outcome (improved vs. stable). Responsiveness for the WOMAC and its subscales were calculated by distribution (effect size; standardized response mean) and anchor-based methods (receiver operating characteristic curves; correlations between change scores of the WOMAC and its subscales and GPE). Receiver operating characteristic curves were also used in order to compute the best cutoff levels between improved and stable subjects (MICs). The effect size ranged from 0.64 to 11.10 and the standardized response mean from 0.79 to 2.65. The receiver operating characteristic analyses revealed an MIC value (area under the curve, sensitivity, specificity) for the WOMAC of 29 (0.817, 92, 78); values of 35 (0.820, 77, 76) 44 (0.625, 25, 95), and 24 (0.707, 100, 76) were found for pain, stiffness, and physical function subscales, respectively. Correlations between change scores of the WOMAC and its subscales and GPE were low (0.240, for stiffness subscale) to moderate (0.438-0.570 for the other subscales and the WOMAC). The WOMAC and its subscales (all but stiffness) were sensitive in detecting clinical changes in subjects with hip fracture undergoing rehabilitation. We recommend taking the MICs provided into account when assessing patients' improvement or planning studies in this clinical context.

    Non-alcoholic fatty liver disease is associated with insulin resistance and dyslipidaemia and can progress to steatohepatitis and cirrhosis. We sought to determine whether dietary fat and saturated fat content alter liver fat in the absence of weight change in an older population. Liver fat was quantified by magnetic resonance spectroscopy before and after 4 weeks on an isoenergetic low-fat/low-saturated fat/low-glycaemic index (LGI) (LSAT: 23% fat/7% saturated fat/GI fat/high-saturated fat/high-GI (HSAT: 43% fat/24% saturated fat/GI > 70) diet in older subjects. In the present study, twenty subjects (seven males/thirteen females; age 69·3 (sem 1·6) years, BMI 26·9 (sem 0·8) kg/m2) were randomised to the LSAT diet and fifteen subjects (six males/nine females; age 68·6 (sem 1·8) years, BMI 28·1 (sem 0·9) kg/m2) to the HSAT diet. Weight remained stable. Liver fat decreased significantly on the LSAT diet (median 2·2 (interquartile range (IQR) 3·1) to 1·7 (IQR 1·8) %, P=0·002) but did not change on the HSAT diet (median 1·2 (IQR 4·1) to 1·6 (IQR 3·9) %). The LSAT diet lowered fasting glucose and total cholesterol, HDL-cholesterol and LDL-cholesterol and raised TAG (Peffect on glucose or HDL-cholesterol but increased total cholesterol and LDL-cholesterol (Pfat. We conclude that diet composition may be an important factor in the accumulation of liver fat, with a low-fat/low-saturated fat/LGI diet being beneficial. PMID:22849970

    Background and objective Despite the strength and consistency of the relationship between body mass index (BMI) and quality of life (QoL), a reduction in BMI does not necessarily lead to an improvement in QoL. Between-subject variability indicates the presence of mediators and moderators in the BMI–QoL association. This study aimed to examine the roles of body image discrepancy (BID) and subjective norm (SN) as potential mediators and moderators. Subjects and methods In 2012, 3,016 volunteers (aged ≥18 years) participated in a community-based survey conducted in the French-speaking region of Belgium. Participation was enhanced using a large multimedia campaign (which was supported by a large network of recruiters) that employed the nonstigmatizing slogan, “Whatever your weight, your opinion will count”. Participants were invited to complete a web-based questionnaire on their weight-related experiences. Self-reported measures were used to calculate each participant’s BMI, BID, SN, and QoL (a French obesity-specific QoL questionnaire was used to calculate the participants’ physical dimension of QoL scores [PHY-QoL], psychosocial dimension of QoL scores [PSY/SOC-QoL], and their total scores). The covariates included gender, age, subjective economic status, level of education, household size, and perceived health. The mediation/moderation tests were based on Hayes’ method. Results Tests showed that the relationships between BMI and PHY-QoL, PSY/SOC-QoL, and TOT-QoL were partially mediated by BID in both males and females and by SN in females. Moreover, BID was a moderator of the relationship between BMI and PSY/SOC-QoL in males and females. SN was a moderator of the relationship between BMI and PSY/SOC-QoL in males and between BMI and total scores in males (when used without BID in the models). Conclusion BID and SN should be considered as important factors in obesity management strategies. The study shows that targeting BMI only is not sufficient to

    Comparative bioavailability studies are conducted to establish the bioequivalence of generic formulation with that of branded reference formulation, providing confidence to clinicians to use these products interchangeably. This study was carried out to compare a locally manufactured formulation of flurbiprofen with that of a branded product. Twenty two healthy male adults received a single dose of flurbiprofen (100mg) either generic or branded product according to randomization scheme on each of 2 periods. Blood samples were collected and plasma flurbiprofen concentration was determined by a validated HPLC method. Pharmacokinetic parameters like AUC(0-t), AUC(0-oo), Cmax, Tmax, t½, Vd and clearance were determined. The 90% CI for the ratio of geometric means of test to reference product's pharmacokinetic variables was calculated. Pharmacokinetic parameters for two formulations were comparable. Ratio of means of AUC(0-24), AUC(0-oo) and Cmax for test to reference products and 90% CI for these ratios were within the acceptable range. The p-values calculated by TOST were much less than the specified value (p-0.05). ANOVA gave p-values which were more than the specified value (p-0.05) for sequence, subject, period and formulation. Test formulation of flurbiprofen (tablet Flurso) was found to meet the criteria for bioequivalence to branded product (tablet Ansaid) based on pharmacokinetic parameters.

    A series of laboratory experiments in a thermally driven, rotating fluid annulus are presented that investigate the onset and characteristics of phase synchronization and frequency entrainment between the intrinsic, chaotic, oscillatory amplitude modulation of travelling baroclinic waves and a periodic modulation of the (axisymmetric) thermal boundary conditions, subject to time-dependent coupling. The time-dependence is in the form of a prescribed duty cycle in which the periodic forcing of the boundary conditions is applied for only a fraction δ of each oscillation. For the rest of the oscillation, the boundary conditions are held fixed. Two profiles of forcing were investigated that capture different parts of the sinusoidal variation and δ was varied over the range 0.1 ≤δ≤1 . Reducing δ was found to act in a similar way to a reduction in a constant coupling coefficient in reducing the width of the interval in forcing frequency or period over which complete synchronization was observed (the "Arnol'd tongue") with respect to the detuning, although for the strongest pulse-like forcing profile some degree of synchronization was discernible even at δ=0.1 . Complete phase synchronization was obtained within the Arnol'd tongue itself, although the strength of the amplitude modulation of the baroclinic wave was not significantly affected. These experiments demonstrate a possible mechanism for intraseasonal and/or interannual "teleconnections" within the climate system of the Earth and other planets that does not rely on Rossby wave propagation across the planet along great circles.

    Although of great public health relevance, the mechanisms underlying disordered eating behavior and body weight regulation remain insufficiently understood. Compelling preclinical evidence corroborates a critical role of the endocannabinoid system (ECS) in the central regulation of appetite and food intake. However, in vivo human evidence on ECS functioning in brain circuits involved in food intake regulation as well as its relationship with body weight is lacking, both in health and disease. Here, we measured cannabinoid 1 receptor (CB1R) availability using positron emission tomography (PET) with [(18)F]MK-9470 in 54 patients with food intake disorders (FID) covering a wide body mass index (BMI) range (anorexia nervosa, bulimia nervosa, functional dyspepsia with weight loss and obesity; BMI range=12.5-40.6 kg/m(2)) and 26 age-, gender- and average BMI-matched healthy subjects (BMI range=18.5-26.6 kg/m(2)). The association between regional CB1R availability and BMI was assessed within predefined homeostatic and reward-related regions of interest using voxel-based linear regression analyses. CB1R availability was inversely associated with BMI in homeostatic brain regions such as the hypothalamus and brainstem areas in both patients with FID and healthy subjects. However, in FID patients, CB1R availability was also negatively correlated with BMI throughout the mesolimbic reward system (midbrain, striatum, insula, amygdala and orbitofrontal cortex), which constitutes the key circuit implicated in processing appetitive motivation and hedonic value of perceived food rewards. Our results indicate that the cerebral homeostatic CB1R system is inextricably linked to BMI, with additional involvement of reward areas under conditions of disordered body weight.

    An increase in arid areas and progressing land degradation are two of the main consequences of global climate change. In the 2nd edition of the World Atlas of Desertification (WAD), published by the United Nation Environment Program (UNEP) in 1997, a global aridity map was presented. This map was based on the Food and Agriculture Organization (FAO) Aridity Index (AI) that takes into account the annual ratio between precipitation (RR) and Potential Evapo-Transpiration (PET). According to the long-term mean value of this ratio, climate is therefore classified in hyper-arid (0.65); a special case are cold climates, which occur if the mean annual PET is below 400 mm. In the framework of the 3rd edition of the WAD, we computed new global aridity maps to improve and update the old version that was based on a single dataset (CRU dataset, Climate Research Unit of University of East Anglia) related to the 1951-80 period only. We computed the AI on two different time intervals (1951-80 and 1981-2010) in order to account for shifts in classes between the two periods and we used two different datasets: PET from CRU (version 3.2), and precipitation from the global 0.5˚x0.5˚ gridded monthly precipitation of the Global Precipitation Climatology Center (GPCC) of the Deutscher Wetterdienst (DWD). We used the GPCC Full Data Reanalysis Version 6.0, which showed a high reliability during many quality checks and is based on more stations than the CRU's precipitation counterpart. The results show that the "arid areas" (i.e. AI Southern Sahara and North-Eastern Kalahari deserts, Rajasthan and Madhya Pradesh (India), Mongolia, the Yang-Tze Basin (China), and the North-Eastern and South-Western Australian coasts. On the other hand, Central U.S., Paraguay and Northern Argentina, Scandinavia, Northern Australia, and Western China moved to a wetter climate in the last period. Due to the low data availability, we assumed that no changes took place in Antarctica, which is meant to be under a

    Background: Low-glycemic index diets have demonstrated health benefits associated with a reduced risk of developing type 2 diabetes.Objectives: We tested whether pomegranate polyphenols could lower the glycemic response of a high-glycemic index food when consumed together and the mechanism by which this might occur.Design: We compared the acute effect of a pomegranate juice and a polyphenol-rich extract from pomegranate (supplement) on the bread-derived postprandial blood glucose concentration in 2 randomized, crossover, controlled studies (double-blinded for the supplements), each on 16 healthy volunteers. An additional randomized, crossover, controlled study on 16 volunteers consuming constituent fruit acids in a pH-balanced solution (same pH as pomegranate) and bread was conducted to determine any contributions to postprandial responses caused by acidic beverages.Results: As primary outcome, the incremental area under the curve for bread-derived blood glucose (-33.1% ± 18.1%, P = 0.000005) and peak blood glucose (25.4% ± 19.3%, P = 0.0004) were attenuated by pomegranate juice, compared with a control solution containing the equivalent amount of sugars. In contrast, the pomegranate supplement, or a solution containing the malic and citric acid components of the juice, was ineffective. The pomegranate polyphenol punicalagin was a very effective inhibitor of human α-amylase in vitro, comparable to the drug acarbose. Neither the pomegranate extract nor the individual component polyphenols inhibited 14C-D-glucose transport across differentiated Caco-2/TC7 cell monolayers, but they inhibited uptake of 14C-glucose into Xenopus oocytes expressing the human glucose transporter type 2. Further, some of the predicted pomegranate gut microbiota metabolites modulated 14C-D-glucose and 14C-deoxy-D-glucose uptake into hepatic HepG2 cells.Conclusions: These data indicate that pomegranate polyphenols, when present in a beverage but not in a supplement, can reduce the

    It was hypothesized that subjects with medical symptoms would show more signs of stress in projective drawings. A Stress Load Index, including five signs of stress in drawings, was evaluated. A questionnaire with an instruction to draw "a person in the rain" was sent to a cohort of 195 subjects, and the drawings were analysed blindly for eight stress items. Men had a higher index than women (p sick building syndrome symptoms (p < .05). In conclusion, a nonverbal projective drawing test detected sex differences which represent directions opposite to those with verbal methods. These need empirical assessment.

    Full Text Available Plasma fibrinogen is an acute phase protein playing an important role in the blood coagulation cascade having strong associations with smoking, alcohol consumption and body mass index (BMI. Genome-wide association studies (GWAS have identified a variety of gene regions associated with elevated plasma fibrinogen concentrations. However, little is yet known about how associations between environmental factors and fibrinogen might be modified by genetic variation. Therefore, we conducted large-scale meta-analyses of genome-wide interaction studies to identify possible interactions of genetic variants and smoking status, alcohol consumption or BMI on fibrinogen concentration. The present study included 80,607 subjects of European ancestry from 22 studies. Genome-wide interaction analyses were performed separately in each study for about 2.6 million single nucleotide polymorphisms (SNPs across the 22 autosomal chromosomes. For each SNP and risk factor, we performed a linear regression under an additive genetic model including an interaction term between SNP and risk factor. Interaction estimates were meta-analysed using a fixed-effects model. No genome-wide significant interaction with smoking status, alcohol consumption or BMI was observed in the meta-analyses. The most suggestive interaction was found for smoking and rs10519203, located in the LOC123688 region on chromosome 15, with a p value of 6.2 × 10(-8. This large genome-wide interaction study including 80,607 participants found no strong evidence of interaction between genetic variants and smoking status, alcohol consumption or BMI on fibrinogen concentrations. Further studies are needed to yield deeper insight in the interplay between environmental factors and gene variants on the regulation of fibrinogen concentrations.

    The passage of time may force people to adjust their subjective age in response to changes in their attitudes toward own aging (ATOA). Although positive associations have been found between well-being and both positive ATOA and younger subjective age, the relationships between changes in these measures have not been examined yet. We expected (1) a decrease in positive ATOA to be associated with an accelerated increase in subjective age and (2) an increase in positive ATOA to be associated with a relative decrease in subjective age. Participants were individuals and their spouses, aged 50 and over, recruited by the Health and Retirement Study, who provided responses to a question concerning one's subjective age in 2008 and 2012 (n = 4174). A change in subjective age over the two waves was regarded as (1) an accelerated increase if it was greater than 5 years (36.2 % of the sample); (2) a relative decrease (39.1 %), if it was less than the 3 years; (3) no change if it did not comply with criteria 1 or 2 (24.7 %). A decrease in positive ATOA over the two waves resulted in an accelerated increase in subjective age, and an increase resulted in a relative decrease in subjective age. Older age and more physical impairments and depressive symptoms in 2012 compared with 2008 were associated with an accelerated increase in subjective age. Our findings emphasize the consequences ATOA might have on subjective age experiences, and the need to improve them.

    Full Text Available Entrepreneurship research is progressing towards the construction of indexes that integrate the information of the three predominant approaches: the entrepreneurial activity output; the population’s entrepreneurial behavior, values and aspirations; and the context in which entrepreneurship takes place. In this study we compare the Global Competitiveness Index data, one of the objective sources of information selected among those recognized as descriptors of national contexts, with the national entrepreneurial context qualitative information provided by the Global Entrepreneurship Monitor. The main purpose of this research is to contribute to the knowledge of entrepreneurial context sources of information by opening a discussion around the usefulness and contribution that could make the Global Entrepreneurship Monitor source in this field, and to determine if it is recommendable to proceed to its formal validation in the short time. The obtained results evidence that the two sources do not overlap to the degree of substituting one by the other and that the Global Entrepreneurship Monitor provides relevant qualitative details about the state of entrepreneurial context that are interesting to complement the Global Competitiveness Index information. The conclusion is to recommend the formal validation of this source, being also necessary to make comparisons with other relevant sources and to clear up its role in the progress of the integrated indexes construction.

  19. How to Distinguish Neutron Star and Black Hole X-ray Binaries? Spectral Index and Quasi-Periodic Oscillation Frequency Correlation

    Science.gov (United States)

    Titarchuk, Lev; Shaposhnikov, Nickolai

    2005-01-01

    Recent studies have revealed strong correlations between 1-10 Hz frequencies of quasiperiodic oscillations (QPOs) and the spectral power law index of several Black Hole (BH) candidate sources when seen in the low/hard state, the steep power-law (soft) state, and in transition between these states. In the soft state these index-QPO frequency correlations show a saturation of the photon index GAMMA approximately equal to 2.7 at high values of the low frequency nu(sub L). This saturation effect was previously identified as a black hole signature. In this paper we argue that this saturation does not occur, at least for one neutron star (NS) source 4U 1728-34, for which the index GAMMA monotonically increases with nu(sub L) to the values of 6 and higher. We base this conclusion on our analysis of approximately 1.5 Msec of RXTE archival data for 4U 1728-34. We reveal the spectral evolution of the Comptonized blackbody spectra when the source transitions from the hard to soft states. The hard state spectrum is a typical thermal Comptonization spectrum of the soft photons which originate in the disk and the NS outer photospheric layers. The hard state photon index is GAMMA approximately 2. The soft state spectrum consists of two blackbody components which are only slightly Comptonized. Thus we can claim (as expected from theory) that in NS sources thermal equilibrium is established for the soft state. To the contrary in BH sources, the equilibrium is never established due to the presence of the BH horizon. The emergent BH spectrum, even in the high/soft state, has a power law component. We also identify the low QPO frequency nu(sub L) as a fundamental frequency of the quasi-spherical component of the transition layer (presumably related to the corona and the NS and disk magnetic closed field lines). The lower frequency nu(sub SL) is identified as the frequency of oscillations of a quasi-cylindrical configuration of the TL (presumably related to the NS and disk magnetic

    To compare strength and endurance variables obtained in the quadriceps muscles of postpolio and control subjects over a 7-year interval with macro and single fiber electromyography (EMG) variables. A controlled inception cohort study. Neuromuscular research laboratory of a university hospital. A cohort of 23 postpolio and 14 control subjects. All postpolio subjects had a history, physical examination, and EMG consistent with previous poliomyelitis, and had greater than antigravity strength in the quadriceps muscle tested. Unstable postpolio subjects acknowledged new quadriceps weakness over the 7-year period of the study (n = 11), and stable postpolio subjects denied new weakness of the quadriceps over the same period (n = 12). All subjects had tests of neuromuscular function of the quadriceps muscles at the onset of this study and yearly over a 7-year period. EMG variables were determined on a separate day after the seventh year of neuromuscular measurements. Neuromuscular variables measured were isometric knee extension peak torque, isometric endurance (time to inability to maintain knee extensor contraction at 40% of maximal torque), tension time index (TTI) (product of isometric endurance time and 40% of maximal torque), and recovery of torque at 10 minutes after the endurance test. EMG variables were macro EMG and single fiber EMG (jitter, fiber density, and percent blocking). Unstable postpolio subjects did not lose strength more rapidly than stable postpolio subjects or control subjects. Unstable postpolio subjects were significantly weaker, had decreased TTI, larger macro EMG amplitude, greater jitter, blocking, and fiber density in comparison with stable postpolio subjects (all p postpolio group (p .05) with neuromuscular or EMG variables in control, stable, or unstable postpolio subjects.

    Standardized Precipitation Evapotranspiration Index (SPEI) is a drought index, its potential is explored to be used as alternative to soil moisture using singular value decomposition (SVD) analysis. To conduct this study, soil moisture was simulated using Community Land Model version 3.5 with National Centre for Environmental Protection (NCEP) 6-h atmospheric-forcing dataset. Due to non-availability of long time continues observed data, simulated soil moisture (0-10 cm depth), is compared with Global Land Data Assimilation System (GLDAS) dataset. Standardized anomalies of area-averaged soil moisture of simulated and GLDAS soil moisture were compared for four different regions of the country. Simulated soil moisture is in strong agreement with GLDAS data. Mann-Kendall test was applied to find trend in soil moisture in the four selected regions. Except Region-1 all the other three regions show declining and significant (p ≤ 0.05) trend. SVD analysis reveals that the correlation between the expansion coefficients is 0.54 and 0.64 for the first and second dominant mode, respectively. First three modes capture more than 90% of the squared covariance fraction. The homogeneous and heterogeneous patterns of first two modes show that soil moisture (decreases) and drought (increases) in the south, while towards the north it is vice versa. Simulated soil moisture follow the same trend as SPEI. SPEI can explain variance of soil moisture.

  3. Stochastic resonance energy harvesting for a rotating shaft subject to random and periodic vibrations: influence of potential function asymmetry and frequency sweep

    2017-11-01

    Stochastic resonance is referred to as a physical phenomenon that is manifest in nonlinear systems whereby a weak periodic signal can be significantly amplified with the aid of inherent noise or vice versa. In this paper, stochastic resonance is considered to harvest energy from two typical vibrations in rotating shafts: random whirl vibration and periodic stick-slip vibration. Stick-slip vibrations impose a constant offset in centrifugal force and distort the potential function of the harvester, leading to potential function asymmetry. A numerical analysis based on a finite element method was conducted to investigate stochastic resonance with potential function asymmetry. Simulation results revealed that a harvester with symmetric potential function generates seven times higher power than that with asymmetric potential function. Furthermore, a frequency-sweep analysis also showed that stochastic resonance has hysteretic behavior, resulting in frequency difference between up-sweep and down-sweep excitations. An electromagnetic energy harvesting system was constructed to experimentally verify the numerical analysis. In contrast to traditional stochastic resonance harvesters, the proposed harvester uses magnetic force to compensate the offset in the centrifugal force. System identification was performed to obtain the parameters needed in the numerical analysis. With the identified parameters, the numerical simulations showed good agreement with the experiment results with around 10% error, which verified the effect of potential function asymmetry and frequency sweep excitation condition on stochastic resonance. Finally, attributed to compensating the centrifugal force offset, the proposed harvester generated nearly three times more open-circuit output voltage than its traditional counterpart.

    Full Text Available Proponents of the efficient market hypothesis believe that active portfolio management is largely wasted effort and unlikely to justify the expenses incurred. Therefore, they advocate a passive investment strategy that makes no attempt to outsmart the market. One common strategy for passive management is indexing where a fund is designed to replicate the performance of a broad-based index of stocks and bonds. Traditionally, indexing was used by institutional investors, but today, the use of index funds proliferated among individual investors. Over the years, both international and domestic index funds have disproportionately outperformed the market more than the actively managed funds have.

  8. An experimental study of unsteady natural convection in a reservoir model subject to periodic thermal forcing using combined PIV and PIT techniques

    2009-07-01

    The present experimental investigation is concerned with the transient flow response in a reservoir model to periodic heating and cooling at the water surface. The experiment reveals a stable stratification of the water body during the heating phase and an unsteady mixing flow in the reservoir during the cooling phase. It is shown that thermal instabilities play an important role in breaking up the residual circulation and initiating a reverse flow circulation in deep waters after the switch of thermal forcing from heating to cooling. Moreover, the heating from the water surface results in a stable large-scale convective roll that is clearly observed in the experiment. The present flow visualization is carried out with the application of thermo-chromic liquid crystals. Quantitative temperature and velocity fields are extracted using Particle Image Thermometry and Particle Image Velocimetry techniques. Understanding of the flow mechanisms pertinent to this problem is important for predicting the transport of nutrients and pollutants across reservoirs.

    Full Text Available Abstract Background To identify objective and subjective indicators of death in prevalent hemodialysis (HD patients in a follow-up study of 12 months. Methods The study included end-stage renal disease patients undergoing HD and analyzed demographic and laboratory data from the dialysis unit's records. Baseline data concerning socioeconomic status, comorbidity, quality of life level, coping style and depression were also assessed. For variables that differed in the comparison between survivors and non-survivors, Cox proportional hazards for death were calculated. Results The mortality rate was 13.0%. Non-survivors differed in age, comorbidity, inclusion on the transplant waiting list and physical functioning score. The hazard ratios of death were 8.958 (2.843-28.223; p p = 0.007 for not being on the transplant waiting list, 1.038 (1.012-1.066; p = 0.005 for age, and 0.980 (0.964-0.996; p = 0.014 for physical functioning. Conclusions Comorbidity, not being on the transplant waiting list, age and physical functioning, which reflects physical status, must be seen as risk indicators of death among patients undergoing HD.

    Time to fitness for work (TFW) was measured as the number of days that were paid as compensation for work disability during the 4 years after discharge from the rehabilitation clinic in a population of patients hospitalised for rehabilitation after orthopaedic trauma. The aim of this study was to test whether some psychological variables can be used as potential early prognostic factors of TFW. A Cox proportional hazards model was used to estimate the associations between predictive variables and TFW. Predictors were global health, pain at hospitalisation and pain decrease during the stay (all continuous and standardised by subtracting the mean and dividing by two standard deviations), perceived severity of the trauma and expectation of a positive evolution (both binary variables). Full data were available for 807 inpatients (660 men, 147 women). TFW was positively associated with better perceived health (hazard ratio [HR] 1.16, 95% confidence interval [CI] 1.13-1.19), pain decrease (HR 1.46, 95% CI 1.30-1.64) and expectation of a positive evolution (HR 1.50, 95% CI 1.32-1.70) and negatively associated with pain at hospitalisation (HR 0.67, 95% CI 0.59-0.76) and high perceived severity (HR 0.72, 95% CI 0.61-0.85). The present results provide some evidence that work disability during a four-year period after rehabilitation may be predicted by prerehabilitation perceptions of general health, pain, injury severity, as well as positive expectation of evolution.

    Despite decades of research on reading, including the relatively recent contributions of neuroimaging and electrophysiology, identifying selective representations of whole visual words (in contrast to pseudowords) in the human brain remains challenging, in particular without an explicit linguistic task. Here we measured discrimination responses to written words by means of electroencephalography (EEG) during fast periodic visual stimulation. Sequences of pseudofonts, nonwords, or pseudowords were presented through sinusoidal contrast modulation at a periodic 10 Hz frequency rate (F), in which words were interspersed at regular intervals of every fifth item (i.e., F/5, 2 Hz). Participants monitored a central cross color change and had no linguistic task to perform. Within only 3 min of stimulation, a robust discrimination response for words at 2 Hz (and its harmonics, i.e., 4 and 6 Hz) was observed in all conditions, located predominantly over the left occipito-temporal cortex. The magnitude of the response was largest for words embedded in pseudofonts, and larger in nonwords than in pseudowords, showing that list context effects classically reported in behavioral lexical decision tasks are due to visual discrimination rather than decisional processes. Remarkably, the oddball response was significant even for the critical words/pseudowords discrimination condition in every individual participant. A second experiment replicated this words/pseudowords discrimination, and showed that this effect is not accounted for by a higher bigram frequency of words than pseudowords. Without any explicit task, our results highlight the potential of an EEG fast periodic visual stimulation approach for understanding the representation of written language. Its development in the scientific community might be valuable to rapidly and objectively measure sensitivity to word processing in different human populations, including neuropsychological patients with dyslexia and other reading

    This study aimed to delineate the prevalence of body image dissatisfaction in pregnant women and parturients in relation to depression and anxiety symptoms. We assessed 126 pregnant women during the third trimester and 2-3days and 4-6weeks after delivery using the Body Image Scale (BIS). Many pregnant participants (34.1%) showed body image dissatisfaction (BIS score ≤3) which was associated with current antenatal depression, severity of depression, a lifetime history of mood disorders, trait anxiety, body mass index (BMI) and weight gain during pregnancy. The BIS score improved after delivery but was still associated with depression, lifetime history of mood disorders, age, BMI and weight gain during pregnancy. These findings suggest that about a third of pregnant women have a body image disturbance which is strongly associated with current and a life history of clinical depression and anxiety symptoms. Medical personnel should be alert to detect body image dissatisfaction in pregnant women because it may indicate an underlying mood disorder. Copyright © 2017 Elsevier B.V. All rights reserved.

    RSV is recognized as an important cause of respiratory tract infections. Immunocompromised patients, health care workers (HCW) and children contacts are at increased risk of acquiring the infection. However, the impact of asymptomatic infection in transmission has not been well studied. This study evaluated the frequency and viral load (VL) of RSV in nasal swab samples of individuals with different risk factors for acquiring infection in a university hospital in Sao Paulo, Brazil. We included 196 symptomatic children and their 192 asymptomatic caregivers, 70 symptomatic and 95 asymptomatic HCW, 43 samples from symptomatic HIV positive outpatients and 100 samples of asymptomatic HIV patients in the period of 2009 to 2013. RSV infection was detected in 10.1% (70/696) of samples, 4.4% (17/387) of asymptomatic patients and 17.1% (53/309) from symptomatic patients. (p< 0.0001). The VL of symptomatic patients (4.7 log copies/mL) was significantly higher compared to asymptomatic patients (2.3 log copies/mL). RSV detection among asymptomatic caregivers (6.8%; 13/192) was significantly higher compared to other asymptomatic adults, HIV and HCWS (2.0%; 4/195; p = 0.0252). A close contact with an infected child at home was an important risk to RSV acquisition [OR 22.6 (95% CI 4.8 to 106.7)].

    Background: Dietary factors can affect telomere length (TL), a biomarker of aging, through oxidation and inflammation-related mechanisms. A Dietary Inflammatory Index (DII) could help to understand the effect of the inflammatory potential of the diet on telomere shortening. Objective: This study aimed to determine the association of the DII with TL and to examine whether diet-associated inflammation could modify the telomere attrition rate after a 5-y follow-up of a Mediterranean dietary intervention. Design: This was a prospective study of 520 participants at high cardiovascular disease risk (mean ± SD age: 67.0 ± 6.0 y, 45% males) from the PREDIMED-NAVARRA (PREvención con DIeta MEDiterránea-NAVARRA) trial. Leukocyte TL was measured by quantitative real-time polymerase chain reaction at baseline and after 5 y of follow-up. The DII was calculated from self-reported data by using a validated 137-item food-frequency questionnaire. Results: Longer telomeres at baseline were found in participants who had a more anti-inflammatory diet (lowest DII score) (P-trend = 0.012). Longitudinal analyses further showed that a greater anti-inflammatory potential of the diet (i.e., a decrease in the DII) could significantly slow down the rate of telomere shortening. Moreover, the multivariable-adjusted OR for short telomeres (z score ≤20th percentile) was 1.80 (95% CI: 1.03, 3.17) in a comparison between the highest (proinflammatory) and the lowest (anti-inflammatory) DII tertiles. Similarly, a greater DII (greatest proinflammatory values) after a 5-y follow-up was associated with almost a 2-fold higher risk of accelerated telomere attrition compared with the highest decrease in DII (greatest anti-inflammatory values) during this period (P-trend = 0.025). Conclusions: This study showed both cross-sectional and longitudinal associations between the inflammatory potential of the diet and telomere shortening in subjects with a high cardiovascular disease risk. Our findings are

    Full Text Available Indexing is one of the most important methods of content representation where by assigning descriptors to the documents, their subject content are made known. Since index and indexing are remarkably significant in information retrieval, its quality and evaluation and provision of criteria and standards had always been the mainstay of researchers in this field. Given the fact that Indexing is a complex process, offering definitions, principles and methods could be step towards optimal use of the information. The present study, while offering a capsule definition of index, will investigate the indexing evaluation criteria and would follow it up with a definition of indexing. Finally a number of standards in the field of indexing are presented and would make its conclusions.

    Diffuse optical spectroscopic imaging (DOSI) and diffuse correlation spectroscopy (DCS) are model-based near-infrared (NIR) methods that measure tissue optical properties (broadband absorption, μa, and reduced scattering, μs‧) and blood flow (blood flow index, BFI), respectively. DOSI-derived μa values are used to determine composition by calculating the tissue concentration of oxy- and deoxyhemoglobin (HbO2, HbR), water, and lipid. We developed and evaluated a combined, coregistered DOSI/DCS handheld probe for mapping and imaging these parameters. We show that uncertainties of 0.3 mm-1 (37%) in μs‧ and 0.003 mm-1 (33%) in μa lead to ˜53% and 9% errors in BFI, respectively. DOSI/DCS imaging of a solid tissue-simulating flow phantom and a breast cancer patient reveals well-defined spatial distributions of BFI and composition that clearly delineates both the flow channel and the tumor. BFI reconstructed with DOSI-corrected μa and μs‧ values had a tumor/normal contrast of 2.7, 50% higher than the contrast using commonly assumed fixed optical properties. In conclusion, spatially coregistered imaging of DOSI and DCS enhances intrinsic tumor contrast and information content. This is particularly important for imaging diseased tissues where there are significant spatial variations in μa and μs‧ as well as potential uncoupling between flow and metabolism.

    The purpose of the study was to examine the association of body mass index (BMI) with the prevalence of chronic disease and health services use in adults living in Newfoundland and Labrador (NL). A cross-sectional analysis of 2345 adult respondents to the 2001 Canadian Community Health Survey was performed. Outcome measures included the prevalence of chronic disease and health services use. The sample comprised normal (37%), overweight (39%), obese (17%), and morbidly obese (6%) individuals. Obese and morbidly obese individuals were more likely to report the presence of a chronic disease. Adjusting for age and sex, increasing BMI category was significantly associated with a greater likelihood of cardiovascular, endocrine, and pulmonary diseases (excluding asthma). The majority of survey respondents in each category reported having a regular doctor (>75%), and there were no significant differences across categories. Compared to those with a normal BMI, obese and morbidly obese individuals reported a significantly higher number of visits to a family physician. There were no differences across BMI categories and the use of specialist or hospital services. Almost a quarter of the study sample in NL was classified as morbidly obese or obese. These individuals reported more chronic conditions and more visits to a family physician than the normal-weight group. The greater morbidity and the increased frequency of visits to family physicians suggests greater consideration should be given to channeling financial and human resources to the primary health care of this high-risk population.

    To describe the derivation and validation of a novel echocardiographic metric for prediction of left ventricle thrombus (LVT). Computational fluid dynamic modeling using cardiac CT images was used to derive a novel echocardiography-based metric to predict the presence of LVT. We retrospectively reviewed 25 transthoracic echocardiograms showing definite LVT (LVT group). We then randomly selected 25 patients with LVEF ≥55% (Normal EF group) and 25 patients with severe cardiomyopathy (CMP) with LVEF ≤40% without evidence of LVT (CMP group). The E-wave Propagation Index (EPI) was measured as the E-wave velocity time-integral divided by the LV length. An EPI>1 indicates penetration of the mitral jet into the apex whereas an EPIEPI was compared between the three groups. Crude and adjusted odd ratios of EPI and LVT association were also measured. Mean EPI was highest for the normal EF group and lowest in the LVT group (1.7 vs. 0.8; pEPI also differed significantly between LVT and CMP groups (0.8 vs. 1.2; pEPI EPI EPI of less than 1 is an independent predictor of LVT formation.

    The gravitational pull of the moon on the earth is not the same in all phases of the lunar month, i.e. new moon (NM), first quarter (FQ), full moon (FM) and third quarter (TQ), and as a result the amplitude of tide differs in different phases. The gravitational pull of the moon may have effects on the fluid compartments of the human body and hence the cardiovascular system may be affected differentially in the different phases of the lunar month. In the present study resting heart rate (HR) and blood pressure (BP), physical fitness index (PFI), peak HR and BP immediately after step test, and recovery HR and BP after step test were measured during different phases of the lunar month in 76 male university students (age 23.7 ± 1.7 years). At rest, both systolic and mean arterial BP were ˜5 mmHg lower in NM and FM compared to FQ and TQ, but resting HR was not significantly different between phases. Further, peak HR and peak systolic BP after step test were lower (˜4 beat/min and ˜5 mmHg, respectively) in NM and FM compared to FQ and TQ. PFI was also higher (˜5) in NM and FM compared to FQ and TQ. Recovery of HR after step test was quicker in NM and FM compared to that of FQ and TQ. It appears from this study that gravitational pull of the moon may affect the cardiovascular functions of the human body. Moreover, the physical efficiency of humans is increased in NM and FM due to these altered cardiovascular regulations.

    Leishmaniasis from Leishmania infantum is a parasitary zoonotic disease and a serious problem to public health. Guidelines from Italian Health Authority (Istituto Superiore di Sanità) suggest to control the zoonotic visceral leishmaniasis canine reservoir in endemic areas using an association of preventive and therapeutic tools. Moreover, in literature there are no studies about the long term effects on the disease seroprevalence and incidence in relation to this "holistic" approach. Past research has considered the effects of the alternative employment of preventive or therapeutic treatment, usually for limited periods. In this retrospective study the patterns of seroprevalence and incidence of leishmaniasis in a dog shelter sited in an endemic area of Central Italy are described throughout a 4-year period. Both preventive spot-on tools (imidacloprid/permetrin) and therapeutic protocols based on antimonials and allopurinol were administered. The results showed a progressive reduction of prevalence and incidence of serological reactivity to L. infantum, corroborating the effectiveness of the treatment administered to the animals. Significant improvements from the beginning to the end of the 4-year period were reported, considering both prevalence and incidence. A very low rate of relapses (8% in a pool of 67 subjects positive since 2004; 10.2% among all subjects enrolled in the study) was achieved.

    The objectives of this retrospective study were to investigate the relationship between temperature-humidity index (THI) and conception rate (CR) of lactating dairy cows, to estimate a threshold for this relationship, and to identify periods of exposure to heat stress relative to breeding in an area of moderate climate. In addition, we compared three different heat load indices related to CR: mean THI, maximum THI, and number of hours above the mean THI threshold. The THI threshold for the influence of heat stress on CR was 73. It was statistically chosen based on the observed relationship between the mean THI at the day of breeding and the resulting CR. Negative effects of heat stress, however, were already apparent at lower levels of THI, and 1 hour of mean THI of 73 or more decreased the CR significantly. The CR of lactating dairy cows was negatively affected by heat stress both before and after the day of breeding. The greatest negative impact of heat stress on CR was observed 21 to 1 day before breeding. When the mean THI was 73 or more in this period, CR decreased from 31% to 12%. Compared with the average maximum THI and the total number of hours above a threshold of more than or 9 hours, the mean THI was the most sensitive heat load index relating to CR. These results indicate that the CR of dairy cows raised in the moderate climates is highly affected by heat stress. Copyright © 2014 Elsevier Inc. All rights reserved.

    A fixed-dose combination (FDC) of amlodipine and losartan has been used to reduce blood pressure in patients whose hypertension is not sufficiently controlled with either drug alone. The aim of this study was to evaluate the pharmacokinetic (PK) characteristics and tolerability of an FDC of 6.94 mg amlodipine besylate (5 mg as amlodipine)/50 mg losartan potassium compared to an FDC of 5 mg amlodipine camsylate/50 mg losartan potassium in healthy subjects. A randomized, open-label, single-dose, two-period, two-sequence crossover study was conducted on 46 healthy male subjects. Blood concentrations were measured by liquid chromatography-tandem mass spectrometry. Blood samples were collected up to 144 hours post dose for each period. PK parameters were calculated in each treatment group using a noncompartmental method. The 90% confidence intervals (CIs) of the geometric mean ratios of the two treatments for the maximum plasma concentration (Cmax) and the area under the concentration curve from time zero to the last quantifiable time point (AUC0-t) were estimated. Tolerability assessments were performed for all subjects who received the drug at least once. The PK profiles of the two treatments were similar. For amlodipine, the geometric mean ratios (90% CIs) of amlodipine besylate to amlodipine camsylate for the Cmax and AUC0-t were 0.98 (0.94-1.01) and 0.97 (0.93-1.01), respectively. The corresponding values for losartan were 0.91 (0.81-1.02) and 1.05 (0.98-1.12), respectively. The incidence of adverse events was not significantly different between the two treatments, and both were well tolerated. An FDC of 6.94 mg amlodipine besylate (5 mg as amlodipine)/50 mg losartan potassium produced similar results to an FDC of 5 mg amlodipine camsylate/50 mg losartan potassium treatment with respect to the PK parameters of amlodipine and losartan based on Cmax and AUC0-t values. The amlodipine besylate/losartan potassium combination was well tolerated by healthy male subjects.

    Acyclovir is an important antiviral drug, used extensively for treatment of herpes simplex and varicella zoster. Six oral generic formulations of acyclovir are available in Mexico; however, a literature search failed to identify data information concerning the bioavailability of these formulations in the Mexican population. The aim of these 2 studies was to compare the bioavailability of 4 oral formulations of acyclovir 400 mg--2 tablet formulations and 2 suspension formulations--with their corresponding listed drug references in Mexico (a list issued by Mexican Health Authorities). Two separate, single-dose, open-label, randomized, 2-period crossover studies were conducted at the Centro de Estudios Científicos y Clínicos Pharma, S.A. de C.V. (clinical unit), Mexico City, Mexico. For each study, a different set of eligible subjects were selected. They included healthy Mexican volunteers of either sex. For each study, subjects were randomly assigned to receive 1 test formulation of acyclovir 400 mg followed by the reference formulation, or vice versa, with a 1-week washout period between doses. After a 12-hour (overnight) fast, subjects received a single 400-mg dose (tablet or 10-mL suspension) of the corresponding formulation. For the analysis of pharmacokinetic properties, including C(max), AUC from time 0 (baseline) to time t (AUC(0-t)), and AUC from baseline to infinity (AUC(0-infinity)), blood samples were drawn at baseline, 0.25, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2, 3, 4, 6, 8, 12, and 24 hours after dosing. The formulations were considered bioequivalent if the natural logarithm (ln)-transformed ratios of Cmax and AUC were within the predetermined equivalence range of 80% to 125% and if P healthy subjects, single, 400-mg doses of the test brand of acyclovir administered either in tablet or suspension form, appeared to be bioequivalent to the reference brand based on the rate and extent of absorption in accordance with the definition of the US Food and Drug

    We present and highlight a partitioning procedure based on the Rao quadratic entropy index to assess temporal in situ inter-annual varietal and genetic changes of crop diversity. For decades, Western-European agroecosystems have undergone profound changes, among which a reduction of crop genetic diversity. These changes have been highlighted in numerous studies, but no unified partitioning procedure has been proposed to compute the inter-annual variability in both varietal and genetic diversity. To fill this gap, we tested, adjusted and applied a partitioning procedure based on the Rao quadratic entropy index that made possible to describe the different components of crop diversity as well as to account for the relative acreages of varieties. To emphasize the relevance of this procedure, we relied on a case study focusing on the temporal evolution of bread wheat diversity in France over the period 1981-2006 at both national and district scales. At the national scale, we highlighted a decrease of the weighted genetic replacement indicating that varieties sown in the most recent years were more genetically similar than older ones. At the district scale, we highlighted sudden changes in weighted genetic replacement in some agricultural regions that could be due to fast shifts of successive leading varieties over time. Other regions presented a relatively continuous increase of genetic similarity over time, potentially due to the coexistence of a larger number of co-leading varieties that got closer genetically. Based on the partitioning procedure, we argue that a tendency of in situ genetic homogenization could be compared to some of its potential causes, such as a decrease in the speed of replacement or an increase in between-variety genetic similarity over time.

The study was realized in the Laboratory of Reproduction of Itutinga Environmental Station of the Energetic Company of Minas Gerais State (EAI-CEMIG and in the Laboratory of Physiology and Pharmacology of DMV/UFLA, during the reproductive period (between November and January in three different reproductive period (year I: 2003/2004; year II: 2004/2005; year III: 2005/2006. After the hormonal treatment, the weight of females spawning was measured. Also, 20µL of semen from each male were collected to analyze the motility, duration of the motility and spermatic concentration. 8 hours after the fertilization, the fertility rate was measured. The average mobility duration and seminal volume did not present significant differences among months of the reproductive period. However, the sperm concentration increased significantly in January. In November, the spawning weight was statistically lower, compared to December and January. The highest fertility rate was observed in December. Therefore, we can conclude that, in December and January, the reproductive index for Prochilodus lineatus was better.Foram avaliadas características seminais e índices reprodutivos de fêmeas e machos de curimba (Prochilodus lineatus em diferentes meses dos períodos reprodutivos.

    Visual deprivation may lead to enhanced performance in other sensory modalities. Whether this is the case in the tactile modality is controversial and may depend upon specific training and experience. We compared the performance of sighted subjects on a Braille character discrimination task to that of normal individuals blindfolded for a period of five days. Some participants in each group (blindfolded and sighted) received intensive Braille training to offset the effects of experience. Blindfolded subjects performed better than sighted subjects in the Braille discrimination task, irrespective of tactile training. For the left index finger, which had not been used in the formal Braille classes, blindfolding had no effect on performance while subjects who underwent tactile training outperformed non-stimulated participants. These results suggest that visual deprivation speeds up Braille learning and may be associated with behaviorally relevant neuroplastic changes.

    Full Text Available To determine the relationship between resistive index (RI measured by Doppler ultrasound, serum creatinine (SCr, and histopathological changes on biopsy during kidney trans- plant dysfunction in early postoperative period, we studied 47 kidney transplant patients; 61% of the patients had acute transplant rejection, 19% had acute tubular necrosis, 4% had calcineurin inhibitor toxicity, 11% had normal morphology in biopsy, and 5% had changes compatible with pyelonephritis. None of the study patients had interstitial fibrosis or tubular atrophy on biopsy. We found that the sensitivity and specificity of RI in diagnosing transplant dysfunction was highly variable depending on the selected cutoff value. Sensitivity of RI decreased and its specificity increased with increasing the RI thresholds. Using an RI threshold of 0.7 resulted in a high sensitivity of 78% at a cost of very low specificity 40%, whereas using an RI threshold of 0.9 resulted in 100% specificity at a cost of very low sensitivity 16%. Acceptable specificity was only achieved at the expense of very low sensitivity, resulting in poor utility of RI as a screening tool for dysfunction. We found that there were no significant differences in the mean RI value between patients with and without biopsy-proven transplant dysfunction. However, we found a significant correlation between SCr value and RI of 0.383, P = 0.007.

    Several studies have reported that variants rs16969968 G>A of the CHRNA5 gene and CYP2A6*12 of the CYP2A6 gene are associated with smoking and smoking refusal, respectively. In addition, some studies report that a higher cigarette consumption is associated with low body mass index (BMI). To analyze the allele and genotypic frequencies of these variants and their impact on smoking and BMI. A blood sample was obtained and a survey about smoking habits was answered by 319 university students aged 18 to 35 years (127 women, 171 smokers), living in Northeastern Mexico. Genetic variants were studied by polymerase chain reaction/restriction fragment length polymorphism and their frequencies were associated with smoking and BMI. No associations were found between the analyzed variants and smoking in the study groups. However, there was an association among non-smoking subjects between the A allele of rs16969968 and high a BMI (p food-addiction disorders.

    Recent trends in indexing emphasize mechanical, not intellectual, developments. Mechanized operations have produced indexes in depth (1) of information on limited areas of science or (2) utilizing limited parameters for analysis. These indexes may include only citations or both useful data and citations of source literature. Both keyword-in-context and citation indexing seem to be passing the test of the marketplace. Mechanical equipment has also been successfully used to manipulate EAM cards for production of index copy. Information centers are increasingly being used as control devices in narrowly defined subject areas. Authors meet growing pressures to participate in information control work by preparing abstracts of their own articles. Mechanized image systems persist, although large systems are scarce and the many small systems may bring only limited relief for information control and retrieval problems. Experimentation and limited development continue on theory and technique of automatic indexing and abstracting. PMID:14306025

    Full Text Available Los pacientes acuden cada vez con más frecuencia a los servicios estomatológicos en busca de mejorar su aspecto estético. Uno de los métodos más polémicos para el examen de la estética lo constituyen aquellos que se basan en el empleo de la proporción divina, esto motivó a la realización de este trabajo. Se evaluó el comportamiento de las proporciones divinas en mediciones dentales de individuos con maloclusión, mediante el empleo del índice de Bolton. Se realizó un estudio descriptivo transversal en estudiantes del segundo al quinto años de la Facultad de Estomatología de La Habana, Cuba, desde el mes de enero del año 2009 al mes de enero del año 2010. Se emplearon modelos de yeso pertenecientes a 80 estudiantes de 18 a 25 años de edad. Se efectuaron mediciones de los anchos mesiodistales de los dientes y se relacionaron algunas secciones de dientes donde se identificaron los que guardaron relación de proporción divina, según la variable oclusión. Los estudiantes que presentaron maloclusión se estudiaron según la variación del índice de Bolton. En los estudiantes con maloclusión el índice de Bolton que predominó fue a favor de un mayor tamaño de los dientes anteroinferiores, con rangos de proporción divina menores de 1,60.Patients came more and more frequently to Stomatology services to improve the esthetic feature. Among the more polemic methods for esthetics examination are those based on the use of divine proportion, leading to carrying out of present paper to assess the behavior of divine proportions in the dental measurements of subjects with malocclusion using the Bolton's index. A cross-sectional and descriptive study was conducted in second to fifth years students of the Stomatology Faculty of La Habana from January, 2009 to January, 2010 using the plaster casts in 80 students aged 18 to 25.

    Obesity development during psychotropic treatments represents a major health issue in psychiatry. Melanin-concentrating hormone receptor 2 (MCHR2) is a central receptor involved in energy homeostasis. MCHR2 shares its promoter region with MCHR2-AS1, a long antisense non-coding RNA. The aim of this study was to determine whether tagging single nucleotide polymorphisms (tSNPs) of MCHR2 and MCHR2-AS1 are associated with the body mass index (BMI) in the psychiatric and in the general population. The influence of MCHR2 and MCHR2-AS1 tSNPs on BMI was firstly investigated in a discovery psychiatric sample (n1 = 474). Positive results were tested for replication in two other psychiatric samples (n2 = 164, n3 = 178) and in two population-based samples (CoLaus, n4 = 5409; GIANT, n5 = 113809). In the discovery sample, TT carriers of rs7754794C>T had 1.08 kg/m2 (p = 0.04) lower BMI as compared to C-allele carriers. This observation was replicated in an independent psychiatric sample (-2.18 kg/m2; p = 0.009). The association of rs7754794C>T and BMI seemed stronger in subjects younger than 45 years (median of age). In the population-based sample, a moderate association was observed (-0.17 kg/m2; p = 0.02) among younger individuals (influence of MCHR2 and/or MCHR2-AS1 on obesity in psychiatric patients and on the pathophysiology of atypical depression.

    Full Text Available Background and aim:\tThe normal range for anthropometric assessment of intercanthal, interpupillary and outer orbital dimensions is important and changes with age. This study was undertaken for setting a reference range for interpupillary distance, the inner and outer intercanthal distances in the normal Indian population, to observe the variation of these parameters with age, any differences in these parameters observed in male & female population and to find correlation with the refractive errors if any. Materials and Methods: This study was conducted in 3500 subjects of both sexes from birth till over 70 years of age, which presented to us in the outpatient department of M & J institute of Ophthalmology and Dr. Thakorbhai V Patel Eye Institute in the period ranging from August 2008 to January 2010. Results: A correlation with refractive errors has not been studied in previous literature. In our study, the range of IPDD in males was found to be 51.87-64.23mm & in females it was 51.16-62.23 mm, range of IPDN was 51.22 – 61.75 mm in males & 47.73-59.93 mm in females. The range of IICD was 18-36.09 mm in males & in females it was 19.38-34.89 mm. The range of OICD in males was 58- 92.8 mm & in females it was 56.63-88.56mm. Conclusion: We present the data for the neonatal children to the older age groups from the same population group. The standards based on local data reflect the potentially different patterns of craniofacial growth resulting from racial, ethnic & sexual differences. These could be relied upon in diagnosis of craniofacial syndromes and orbito-facial trauma or for planning reconstructive surgeries for the same.

  1. Walkability Index

    Science.gov (United States)

    The Walkability Index dataset characterizes every Census 2010 block group in the U.S. based on its relative walkability. Walkability depends upon characteristics of the built environment that influence the likelihood of walking being used as a mode of travel. The Walkability Index is based on the EPA's previous data product, the Smart Location Database (SLD). Block group data from the SLD was the only input into the Walkability Index, and consisted of four variables from the SLD weighted in a formula to create the new Walkability Index. This dataset shares the SLD's block group boundary definitions from Census 2010. The methodology describing the process of creating the Walkability Index can be found in the documents located at ftp://newftp.epa.gov/EPADataCommons/OP/WalkabilityIndex.zip.

    Full Text Available This paper approaches the subject of Weather Derivatives, more exactly their basic element the weather index. The weather index has two forms, the Heating Degree Day (HDD and the Cooling Degree Day (CDD. We will try to explain their origin, use and the relationship between the two forms of the index. In our research we started from the analysis of the weather derivatives and what they are based on. After finding out about weather index, we were interested in understanding exactly how they work and how they influence the value of the contract. On the national level the research in the field is scares, but foreign materials available. The study for this paper was based firstly on reading about Weather Derivative, and then going in the meteorogical field and determining the way by which the indices were determined. After this, we went to the field with interest in the indices, such as the energy and gas industries, and figured out how they determined the weather index. For the examples we obtained data from the weather index database, and calculated the value for the period. The study is made on a period of five years, in 8 cities of the European Union. The result of this research is that we can now understand better the importance of the way the indices work and how they influence the value of the Weather Derivatives. This research has an implication on the field of insurance, because of the fact that weather derivative are at the convergence point of the stock markets and the insurance market. The originality of the paper comes from the personal touch given to the theoretical aspect and through the analysis of the HDD and CDD index in order to show their general behaviour and relationship.

    Full Text Available Long-term global data sets of vegetation Leaf Area Index (LAI and Fraction of Photosynthetically Active Radiation absorbed by vegetation (FPAR are critical to monitoring global vegetation dynamics and for modeling exchanges of energy, mass and momentum between the land surface and planetary boundary layer. LAI and FPAR are also state variables in hydrological, ecological, biogeochemical and crop-yield models. The generation, evaluation and an example case study documenting the utility of 30-year long data sets of LAI and FPAR are described in this article. A neural network algorithm was first developed between the new improved third generation Global Inventory Modeling and Mapping Studies (GIMMS Normalized Difference Vegetation Index (NDVI3g and best-quality Terra Moderate Resolution Imaging Spectroradiometer (MODIS LAI and FPAR products for the overlapping period 2000–2009. The trained neural network algorithm was then used to generate corresponding LAI3g and FPAR3g data sets with the following attributes: 15-day temporal frequency, 1/12 degree spatial resolution and temporal span of July 1981 to December 2011. The quality of these data sets for scientific research in other disciplines was assessed through (a comparisons with field measurements scaled to the spatial resolution of the data products, (b comparisons with broadly-used existing alternate satellite data-based products, (c comparisons to plant growth limiting climatic variables in the northern latitudes and tropical regions, and (d correlations of dominant modes of interannual variability with large-scale circulation anomalies such as the EI Niño-Southern Oscillation and Arctic Oscillation. These assessment efforts yielded results that attested to the suitability of these data sets for research use in other disciplines. The utility of these data sets is documented by comparing the seasonal profiles of LAI3g with profiles from 18 state-of-the-art Earth System Models: the models

  10. The great contribution: Index Medicus, Index-Catalogue, and IndexCat.

    2009-04-01

    The systematic indexing of medical literature by the Library of the Surgeon-General's Office (now the National Library of Medicine) has been called "America's greatest contribution to medical knowledge." In the 1870s, the library launched two indexes: the Index Medicus and the Index-Catalogue of the Library of the Surgeon-General's Office. Index Medicus is better remembered today as the forerunner of MEDLINE, but Index Medicus began as the junior partner of what the library saw as its major publication, the Index-Catalogue. However, the Index-Catalogue had been largely overlooked by many medical librarians until 2004, when the National Library of Medicine released IndexCat, the online version of Index-Catalogue. Access to this huge amount of material raised new questions: What was the coverage of the Index-Catalogue? How did it compare and overlap with the Index Medicus? Over 1,000 randomly generated Index Medicus citations were cross-referenced in IndexCat. Inclusion, form, content, authority control, and subject headings were evaluated, revealing that the relationship between the two publications was neither simple nor static through time. In addition, the authors found interesting anomalies that shed light on how medical literature was selected and indexed in "America's greatest contribution to medical knowledge."

    periodicals. The analysis is based on a perspective of Human Rights, and on the theoretical constructs of social and historical Social Psychology. It indicates that the educational model used in the context of deprived freedom is similar to that of regular education offered inschools within the community, which appears to hinder the effectiveimplementation of the right to education for young people with deprived freedom,and of an educational practice that would better take into account the specific context, profile, and objective and concrete reality of the students. In the articles studied, the education of adolescents deprived of freedom is addressed from aperspective of right and obligation/duty. For the adolescents researched, education in the context of deprived freedom is mainly associated with a sense of obligation/duty. The data indicate the existence of contradictions and conflicts between right and obligation, and a fragility of the educational process as a trainingof the autonomous subject. Problems are also indicated in relation to the training of teachers to work in the context of deprived freedom. It is concluded, based on the data from the literature review, that there is a prevalence of ineffective practices in terms of a human training that is in keeping with the transformation of the concretereality. Adolescents deprived of freedom tend not to be recognized as subjects with rights. A legalistic view tends to obscure that of the guarantee of the right. This analysis is present in the majority of the articles, some with greater emphasis and others with less, or is seen in the empirical basis of their respective studies, which differ in their theoretical and methodological approaches.

    Full Text Available Indexers often disagree on judging terms that best reflect the content of a document. Difference of opinion highlights one of the characteristics of indexing which is indexing cohesion. Also known as consistency, little study of the subject matter has been undertaken in the past few years. However, its importance has been recently acknowledged in effective information retrieval and expansion of access points to the document content. The present paper investigates cohesion in indexing. In addition of presenting the definitions offered by experts, it takes note of the factors influencing indexing cohesion. Methods for measuring cohesion are offered.

    Acne vulgaris may be improved by dietary factors that increase insulin sensitivity. We hypothesized that a low-glycemic index diet would improve facial acne severity and insulin sensitivity. Fifty-eight adolescent males (mean age ± standard deviation 16.5 ± 1.0 y and body mass index 23.1 ± 3.5 kg/m(2)) were alternately allocated to high or low glycemic index diets. Severity of inflammatory lesions on the face, insulin sensitivity (homeostasis modeling assessment of insulin resistance), androgens and insulin-like growth factor-1 and its binding proteins were assessed at baseline and at eight weeks, a period corresponding to the school term. Forty-three subjects (n = 23 low glycemic index and n = 20 high glycemic index) completed the study. Diets differed significantly in glycemic index (mean ± standard error of the mean, low glycemic index 51 ± 1 vs. high glycemic index 61 ± 2, p = 0.0002), but not in macronutrient distribution or fiber content. Facial acne improved on both diets (low glycemic index -26 ± 6%, p = 0.0004 and high glycemic index -16 ± 7%, p = 0.01), but differences between diets did not reach significance. Change in insulin sensitivity was not different between diets (low glycemic index 0.2 ± 0.1 and high glycemic index 0.1 ± 0.1, p = 0.60) and did not correlate with change in acne severity (Pearson correlation r = -0.196, p = 0.244). Longer time frames, greater reductions in glycemic load or/and weight loss may be necessary to detect improvements in acne among adolescent boys.

    The International Energy Subject Thesaurus contains the standard vocabulary to indexing terms (descriptors) developed and structured to build and maintain energy information databases. Involved in this cooperative task are (1) the technical staff of the USDOE Office of Scientific and Technical Information (OSTI) in cooperation with the member countries of the Energy Technology Data Exchange (ETDE) and (2) the International Nuclear Information System (INIS) staff representing the more than ninety countries and organizations recording and indexing information for the international nuclear information community. ETDE member countries are also members of the International Nuclear Information System (INIS). Nuclear information indexed and recorded for INIS by these ETDE member countries is also included in the ETDE Energy Data Base, and indexing terminology is therefore cooperatively standardized for use in both information systems. This structured vocabulary reflects the scope of international energy research, development, and technological programs and encompasses terminology derived not only from the basic sciences but also from the areas of energy resources, conservation, safety, environmental impact, and regulation.

  13. Beyond the floor effect on the Wechsler Intelligence Scale for Children--4th Ed. (WISC-IV): calculating IQ and Indexes of subjects presenting a floored pattern of results.

    It is now widely known that children with severe intellectual disability show a 'floor effect' on the Wechsler scales. This effect emerges because the practice of transforming raw scores into scaled scores eliminates any variability present in participants with low intellectual ability and because intelligence quotient (IQ) scores are limited insofar as they do not measure scores lower than 40. Following Hessl et al.'s results, the present authors propose a method for the computation of the Wechsler Intelligence Scale for Children--4th Ed. (WISC-IV)'s IQ and Indexes in intellectually disabled participants affected by a floored pattern of results. The Italian standardization sample (n = 2200) for the WISC-IV was used. The method presented in this study highlights the limits of the 'floor effect' of the WISC-IV in children with serious intellectual disability who present a profile with weighted scores of 1 in all the subtests despite some variability in the raw scores. Such method eliminates the floor effect of the scale and therefore makes it possible to analyse the strengths and weaknesses of the WISC-IV's Indexes in these participants. The Authors reflect on clinical utility of this method and on the meaning of raw score of 0 on subtest. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    The technical staff of the DOE Technical Information Center, during its subject indexing activities, develops and structures a vocabulary that allows consistent machine storage and retrieval of information necessary to the accomplishment of the DOE mission. This thesaurus incorporates that structured vocabulary. The terminology of this thesaurus is used for the subject control of information announced in DOE Energy Research Abstracts, Energy Abstracts for Policy Analysis, and various update journals and bulletins in specialized areas. This terminology also facilitates subject searching of the DOE Energy Data Base on the DOE/RECON on-line retrieval system and on other commercial retrieval systems. The rapid expansion of the DOE's activities will result in a commitant thesaurus expansion as information relating to new activities is indexed. Only the terms used in the indexing of documents at the Technical Information Center to date are included. (JSR)

    Full Text Available Epidemiological studies suggest that excessive sitting time is associated with increased health risk, independent of the performance of exercise. We hypothesized that a daily bout of exercise cannot compensate the negative effects of inactivity during the rest of the day on insulin sensitivity and plasma lipids.Eighteen healthy subjects, age 21±2 year, BMI 22.6±2.6 kgm(-2 followed randomly three physical activity regimes for four days. Participants were instructed to sit 14 hr/day (sitting regime; to sit 13 hr/day and to substitute 1 hr of sitting with vigorous exercise 1 hr (exercise regime; to substitute 6 hrs sitting with 4 hr walking and 2 hr standing (minimal intensity physical activity (PA regime. The sitting and exercise regime had comparable numbers of sitting hours; compared to the exercise regime, the minimal intensity PA regime had a higher estimated daily energy expenditure (238kcal/day [corrected]. PA was assessed continuously by an activity monitor (ActivPAL and a diary. Measurements of insulin sensitivity (oral glucose tolerance test, OGTT and plasma lipids were performed in the fasting state, the morning after the 4 days of each regime. In the sitting regime, daily energy expenditure was about 500 kcal lower than in both other regimes. Area under the curve for insulin during OGTT was significantly lower after the minimal intensity PA regime compared to both sitting and exercise regimes 6727.3±4329.4 vs 7752.0±3014.4 and 8320.4±5383.7 mU•min/ml, respectively. Triglycerides, non-HDL cholesterol and apolipoprotein B plasma levels improved significantly in the minimal intensity PA regime compared to sitting and showed non-significant trends for improvement compared to exercise.One hour of daily physical exercise cannot compensate the negative effects of inactivity on insulin level and plasma lipids if the rest of the day is spent sitting. Reducing inactivity by increasing the time spent walking/standing is more effective than

    Full Text Available Several investigations have been carried out to identify the factors that are responsible for the day-to-day variability in the occurrence of equatorial spread-F (ESF. But the precise forecasting of ESF on a day-to-day basis is still far from reality. The nonlinear development and the sustenance of ESF/plasma bubbles is decided by the background ionospheric conditions, such as the base height of the F-layer (h'F, the electron density gradient (dN/dz, maximum ionization density (Nmax, geomagnetic activity and the neutral dynamics. There is increasing evidence in the literature during the recent past that shows a well developed Equatorial Ionization Anomaly (EIA during the afternoon hours contributes significantly to the initiation of ESF during the post-sunset hours. Also, there exists a good correlation between the Equatorial Ionization Anomaly (EIA and the Integrated Equatorial ElectroJet (IEEJ strength, as the driving force for both is the same, namely, the zonal electric field at the equator. In this paper, we present a linear relationship that exists between the daytime integrated equatorial electrojet (IEEJ strength and the maximum elevated height of the F-layer during post-sunset hours (denoted as peak h'F. An inverse relationship that exists between the 6-h average Kp-index prior to the local sunset and the peak h'F of the F-layer is also presented. A systematic study on the combined effects of the IEEJ and the average Kp-index on the post-sunset, peak height of the F-layer (peak h'F, which controls the development of ESF/plasma bubbles, is carried out using the ionosonde data from an equatorial station, Trivandrum (8.47° N, 76.91° E, dip.lat. 0.5° N, an off-equatorial station, SHAR (13.6° N, 79.8° E, dip.lat. 10.8° N and VHF scintillations (244 MHz observed over a nearby low-latitude station, Waltair (17.7° N, 83.3° E, dip.lat. 20° N.

    In the period from 1984 to 1993 the Bavarian Project Group for Research into the Effects of Pollutants (PBWU), a division of the GSF Research Centre, coordinated research activities on forest damage on behalf of the Bavarian Ministry for Agriculture and Environment (StMLU). These activities comprised a total of approximately 80 research projects which were conducted by Bavarian reserach institutes. Most of the projects were dedicated to research into the effects of pollution. The complex interactions prevailing in forest ecosystems are reflected in the wide variety of research topics dealt with, which ranged form the determination of pollutant deposition, atmospheric chemistry, over biochemical and physiological mechanisms of pollutant uptake in tree to soil analyses taking fibrous roots and mycorrhiza into account. The field studies were conducted at the interdisciplinary research bases of the Bavarian forest damage research programme, among which the Wank research base plays an outstanding role. They were flanked by laboratory work and controlled experiments performed in the exposition chambers of the GSF. Even though numerous questions relating to material processes and to alterations in forest ecosystems remain to be solved, at lest in some research areas it is now possible to derive conclusive statements from the results of the conducted forest damage research. This report sums up the results obtained. (orig.)

    The objective of this study was to identify the optimal index of greenness in terms of psychophysiological responses and subjective preference. We recruited 103 adult (51 male, 52 female) participants, who were examined individually in an interior space (lab) setting at Konkuk University, Seoul, South Korea. Participants observed plants in the space for 3min per experimental index of greenness (5%, 20%, 50%, and 80%). During this period, heart rate variability (HRV) and electroencephalographic (EEG) physiological responses were measured, and the participant's preference for index of greenness and subjective index of greenness was determined via surveys. HRV values were normal, and not significantly different, except that male participants showed higher mean variability between cardiac NN intervals and greater autonomic activity than female participants (Pspace, even a small amount of greenery may exert a relaxing effect on people.

    Full Text Available Abstract Background: Indexing is a crucial step in any information retrieval system. In MEDLINE, a widely used database of the biomedical literature, the indexing process involves the selection of Medical Subject Headings in order to describe the subject matter of articles. The need for automatic tools to assist MEDLINE indexers in this task is growing with the increasing number of publications being added to MEDLINE. Methods: In this paper, we describe the use and the customization of Inductive Logic Programming (ILP to infer indexing rules that may be used to produce automatic indexing recommendations for MEDLINE indexers. Results: Our results show that this original ILP-based approach outperforms manual rules when they exist. In addition, the use of ILP rules also improves the overall performance of the Medical Text Indexer (MTI, a system producing automatic indexing recommendations for MEDLINE. Conclusion: We expect the sets of ILP rules obtained in this experiment to be integrated into MTI.

    Hypertension is a risk factor for a long-lasting arterial wall-remodelling leading to stiffness. The rapid method measuring the pulse pressure (PP) by means of the tool of Hypertension Diagnostic Instruments (HDI) called PP-HDI, overcomes some of the problems arising with more-time consuming methods, like ambulatory blood pressure monitoring (ABPM), and give information about the elasticity of the arterial walls. We studied the relationship between the PP-HDI, the large artery compliance (LA-C) and small artery compliance (SA-C) and few well-established indices of arterial blood pressure (ABP) in a sample of 75 hypertensive subjects, aged 65 years and over. Significant correlations between LA-C and heart rate (HR), PP-ABPM and PP-HDI were found. SA-C relates with HR and systolic blood pressure (SBP) measured in lying and standing positions. Applying a stepwise regression analysis, we found that LA-C variance stems from PP-HDI and HR, while SA-C variance stems from SBP in lying position. Receiver operator characteristic (ROC) curves for thresholds of PP showed that PP-HDI reached levels of sensitivity/specificity similar to PP-ABPM. In conclusion, surveillance of ABP through hemo-dynamic indices, in particular of SBP, is essential, nevertheless the advantage of this control is not known in an elderly population where the organ damage is already evident. PP needs necessarily an instrumental measurement. The PP-HDI result is similar in reliability with respect to PPABPM, but is more rapid and well applicable in an elderly population.

    Schizophrenia (SZ) patients have information processing deficits, spanning from low level sensory processing to higher-order cognitive functions. Mismatch negativity (MMN) and P3a are event-related potential (ERP) components that are automatically elicited in response to unattended changes in ongoing, repetitive stimuli that provide a window into abnormal information processing in SZ. MMN and P3a are among the most robust and consistently identified deficits in SZ, yet the neural substrates of these responses and their associated deficits in SZ are not fully understood. This study examined the neural sources of MMN and P3a components in a large cohort of SZ and nonpsychiatric control subjects (NCS) using Exact Low Resolution Electromagnetic Tomography Analyses (eLORETA) in order to identify the neural sources of MMN and P3a as well as the brain regions associated with deficits commonly observed among SZ patients. 410 SZ and 247 NCS underwent EEG testing using a duration-deviant auditory oddball paradigm (1-kHz tones, 500ms SOA; standard p=0.90, 50-ms duration; deviant tones P=0.10, 100-ms duration) while passively watching a silent video. Voxel-by-voxel within- (MMN vs. P3a) and between-group (SZ vs. NCS) comparisons were performed using eLORETA. SZ had robust deficits in MMN and P3a responses measured at scalp electrodes consistent with other studies. These components mapped onto neural sources broadly distributed across temporal, frontal, and parietal regions. MMN deficits in SZ were associated with reduced activations in discrete medial frontal brain regions, including the anterior-posterior cingulate and medial frontal gyri. These early sensory discriminatory MMN impairments were followed by P3a deficits associated with widespread reductions in the activation of attentional networks (frontal, temporal, parietal regions), reflecting impaired orienting or shifts of attention to the infrequent stimuli. MMN and P3a are dissociable responses associated with broadly

    The consumption of low glycemic index (LGI) foods before exercise results in slower and more stable glycemic increases. Besides maintaining an adequate supply of energy during exercise, this response may favor an increase in fat oxidation in the postprandial period before the exercise compared to high glycemic index (HGI) foods. The majority of the studies that evaluated the effect of foods differing in glycemic index on substrate oxidation during the postprandial period before the exercise are acute studies in which a single meal is consumed right before the exercise. The purpose of this study was to investigate the effect of consuming two daily HGI or LGI meals for five consecutive days on substrate oxidation before the exercise and in the concentrations of glucose, insulin and free fatty acids before and during a high intensity exercise. Fifteen male cyclists, aged 24.4 ± 3.8 years, with body mass index of 21.9 ± 1.4 kg.m⁻² and a V(O2 max) of 70.0 ± 5.3 mL.kg⁻¹.min⁻¹, participated in this crossover study. All test meals were consumed in the laboratory. On days 1 and 5, substrate oxidation (30 minutes before and 90 minutes after breakfast (HGI or LGI)) and diet-induced thermogenesis (90 minutes postprandial) were assessed before the exercise. The levels of glucose, insulin, and free fatty acids were determined during 2 h after breakfast on these same days. Ninety minutes after breakfast, subjects completed a 30 min cycloergometric exercise at 85 to 95% of their maximum heart rate, during which lactate concentrations were assessed. The consumption of HGI meals resulted in higher areas under the glycemic and insulinemic curves in the postprandial period. However, glycemia did not differ by study treatment during exercise. There were no differences in free fatty acids in the postprandial period or in lactate levels during exercise. LGI meals resulted in lower fat oxidation and higher carbohydrate oxidation than the HGI meal in the postprandial period

    Fieldwork is one of the important methods in educational, social, and organisational research. In fieldwork, the researcher takes residence for a shorter or longer period amongst the subjects and settings to be studied. The aim of this is to study the culture of people: how people seem to make...... sense of their lives and which moral, professional, and ethical values seem to guide their behaviour and attitudes. In fieldwork, the researcher has to balance participation and observation in her attempts at representation. Consequently, the researcher’s academic and life-historical subjectivity...... are important filters for fieldwork. In general, fieldwork can be understood as processes where field reports and field analysis are determined by how the researcher interacts with and experiences the field, the events and informants in it, and how she subsequently develops an ethnography.

    Full Text Available It is quite impressive the visibility of online publishing compared to offline. Lawrence (2001 computed the percentage increase across 1,494 venues containing at least five offline and five online articles. Results shown an average of 336% more citations to online articles compared to offline articles published in the same venue. If articles published in the same venue are of similar quality, then they concluded that online articles are more highly cited because of their easier access. Thomson Scientific, traditionally concerned with printed journals, announced on November 28, 2005, the launch of Web Citation Index™, the multidisciplinary citation index of scholarly content from institutional and subject-based repositories (http://scientific.thomson. com/press/2005/8298416/. The Web Citation Index from the abstracting and indexing (A&I connects together pre-print articles, institutional repositories and open access (OA journals (Chillingworth, 2005. Basically all research funds are government granted funds, tax payer’s supported and therefore, results should be made freely available to the community. Free online availability facilitates access to research findings, maximizes interaction among research groups, and optimizes efforts and research funds efficiency. Therefore, Ambi-Água is committed to provide free access to its articles. An important aspect of Ambi-Água is the publication and management system of this journal. It uses the Electronic System for Journal Publishing (SEER - http://www.ibict.br/secao.php?cat=SEER. This system was translated and customized by the Brazilian Institute for Science and Technology Information (IBICT based on the software developed by the Public Knowledge Project (Open Journal Systems of the British Columbia University (http://pkp.sfu.ca/ojs/.

    Patients with restless leg syndrome (RLS) complain of motor restlessness, usually occurring while they rest in the evening. Two immobilization tests have been described to assess leg restlessness in these patients. In the first test, the patient sits in bed with his or her legs outstretched while electromyograms are recorded from right and left anterior tibialis muscles for an hour (Suggested Immobilization Test [SIT]); in the second test, the legs are immobilized in a stretcher (Forced Immobilization Test [FIT]). In the current study, the SIT and the FIT were compared in patients with RLS and normal control subjects matched for age and sex. More leg movements were seen in patients than in controls during immobilization tests, especially the SIT. These movements were periodic, occurring at a frequency of approximately one every 12 seconds. The SIT (index > 40) was found to discriminate between RLS and control subjects better than the FIT (index > 25). Patients were also recorded during two consecutive nights to measure periodic leg movements in sleep (PLMS). A SIT index greater than 40 and a PLMS index greater than 11 (highest PLMS index of 2 consecutive nights) were found to discriminate patients with RLS from control subjects with similar power. With each of these two measures, the clinical diagnosis was correctly predicted in 81% of patients and 81% of the control subjects. The SIT has several advantages over the measure of the PLMS index; it does not require an all-night polygraphic recording and can be administered several times a day to measure circadian fluctuation of motor restlessness.

  16. Children grow and horses race: is the adiposity rebound a critical period for later obesity?

    Full Text Available Abstract Background The adiposity rebound is the second rise in body mass index that occurs between 3 and 7 years. An early age at adiposity rebound is known to be a risk factor for later obesity. The aim here is to clarify the connection between the age at rebound and the corresponding pattern of body mass index change, in centile terms, so as to better understand its ability to predict later fatness. Discussion Longitudinal changes in body mass index during adiposity rebound, measured both in original (kg/m2 and standard deviation (SD score units, are studied in five hypothetical subjects. Two aspects of the body mass index curve, the body mass index centile and the rate of body mass index centile crossing, determine a child's age at rebound. A high centile and upward centile crossing are both associated separately with an early rebound, while a low centile and/or downward centile crossing correspond to a late rebound. Early adiposity rebound is a risk factor for later fatness because it identifies children whose body mass index centile is high and/or crossing upwards. Such children are likely to have a raised body mass index later in childhood and adulthood. This is an example of Peto's "horse racing effect". The association of centile crossing with later obesity is statistical not physiological, and it applies at all ages not just at rebound, so adiposity rebound cannot be considered a critical period for future obesity. Body mass index centile crossing is a more direct indicator of the underlying drive to fatness. Summary An early age at adiposity rebound predicts later fatness because it identifies children whose body mass index centile is high and/or crossing upwards. Such children are likely to have a raised body mass index later. Body mass index centile crossing is more direct than the timing of adiposity rebound for predicting later fatness.

    1997-01-01

    No core list of periodicals exists for speech pathology and audiology. Faced with the prospect of having to cancer periodicals for all subjects, the science librarians at Illinois State University decided to determine which science periodicals were used most heavily. A one-year study of science periodical reshelving and interlibrary loan requests yielded ranked lists of periodicals important to speech pathology and audiology faculty and students at Illinois State University. The three most heavily used journals were the Journal of Speech and Hearing Research, ASHA, and Topics in Language Disorders. Most of the periodicals on the lists were indexed by either MEDLINE or UnCover, or by both. While the lists of journals developed in the study are not sufficient to serve as true core lists, they should be useful to libraries supporting comparable programs in speech pathology and audiology.

    Patients with IgA deficiency and agammaglobulinemia were pair-matched to immunocompetent subjects by age and Plaque Index. Clinical examinations performed initially and after 2 years included the Plaque Index, Gingival Index, Periodontal Disease Index, caries experience (DMF-T) and full mouth radiographic surveys. Therapy during the 2-year period included oral hygiene instructions, prophylaxis and indicated restorative treatment. Immunodeficient patients manifested consistently lower levels of gingival inflammation than matched immunocompetent patients at both examination periods. Caries experience of immunodeficient patients was also less during the study interval, and five of these patients demonstrated DMF-T scores of zero. No developmental abnormalities, acute gingival or mucosal lesions, or attachment loss associated with periodontitis was observed in either group.

    The effects of carbohydrates on plasma uric acid levels are a subject of controversy. We determined the individual and combined effects of carbohydrate quality (the glycemic index) and quantity (the proportion of total daily energy [percentage of carbohydrates]) on uric acid levels. We conducted a randomized, crossover trial of 4 different diets in overweight or obese adults without cardiovascular disease (n = 163). Participants consumed each of 4 diets over a 5-week period, each of which was separated by a 2-week washout period. Body weight was kept constant. The 4 diets were high glycemic index (≥65) with high percentage of carbohydrates (58% kcal), low glycemic index (≤45) with low percentage of carbohydrates (40% kcal), low glycemic index with high percentage of carbohydrates, and high glycemic index with low percentage of carbohydrates. Plasma uric acid levels were measured at baseline and after completion of each 5-week period for comparison between the 4 diets. Of the 163 study participants, 52% were women and 50% were non-Hispanic African American subjects; their mean age was 52.6 years, and their mean ± SD uric acid level was 4.7 ± 1.2 mg/dl. Reducing the glycemic index lowered uric acid levels when the percentage of carbohydrates was low (-0.24 mg/dl; P glycemic index was high (P = 0.05). The combined effect of lowering the glycemic index and increasing the percentage of carbohydrates was -0.27 mg/dl (P glycemic index lowers uric acid levels. Future studies should examine whether reducing the glycemic index can prevent gout onset or flares. © 2016, American College of Rheumatology.

    This study develops two sub-indexes of port classification and capacity, and combines cases of these two sub-indexes into various types in order to find a proper port hub index. The paper demonstrates how different types of port hub index are useful measurements for evaluating outputs and inputs of container ports. In a case analysis we show that the indexes of period variables and lagged variables have more explanatory power with regard to changes of port throughputs and high correlation with inputs.

    Abstract Background The consumption of low glycemic index (LGI) foods before exercise results in slower and more stable glycemic increases. Besides maintaining an adequate supply of energy during exercise, this response may favor an increase in fat oxidation in the postprandial period before the exercise compared to high glycemic index (HGI) foods. The majority of the studies that evaluated the effect of foods differing in glycemic index on substrate oxidation during the postprandial period b...

    Full Text Available Acne vulgaris may be improved by dietary factors that increase insulin sensitivity. We hypothesized that a low-glycemic index diet would improve facial acne severity and insulin sensitivity. Fifty-eight adolescent males (mean age ± standard deviation 16.5 ± 1.0 y and body mass index 23.1 ± 3.5 kg/m2 were alternately allocated to high or low glycemic index diets. Severity of inflammatory lesions on the face, insulin sensitivity (homeostasis modeling assessment of insulin resistance, androgens and insulin-like growth factor-1 and its binding proteins were assessed at baseline and at eight weeks, a period corresponding to the school term. Forty-three subjects (n = 23 low glycemic index and n = 20 high glycemic index completed the study. Diets differed significantly in glycemic index (mean ± standard error of the mean, low glycemic index 51 ± 1 vs. high glycemic index 61 ± 2, p = 0.0002, but not in macronutrient distribution or fiber content. Facial acne improved on both diets (low glycemic index −26 ± 6%, p = 0.0004 and high glycemic index −16 ± 7%, p = 0.01, but differences between diets did not reach significance. Change in insulin sensitivity was not different between diets (low glycemic index 0.2 ± 0.1 and high glycemic index 0.1 ± 0.1, p = 0.60 and did not correlate with change in acne severity (Pearson correlation r = −0.196, p = 0.244. Longer time frames, greater reductions in glycemic load or/and weight loss may be necessary to detect improvements in acne among adolescent boys.

    The goal of this study was to describe family history and inheritance patterns in patients with periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis (PFAPA) syndrome. We performed a case-control study to compare the family histories of patients with PFAPA recruited from Vanderbilt University Medical Center and matched healthy control subjects from a pediatric primary care practice in Nashville, Tennessee, by using a structured questionnaire. Characteristics of paired case subjects, control subjects, and their family members were compared by using McNemar's test and Wilcoxon signed-rank tests. Eighty PFAPA index case subjects and 80 control subjects were recruited. Eighteen PFAPA case subjects (23%) had ≥1 family member with PFAPA. Parents of PFAPA index case subjects were more likely to have recurrent pharyngitis (36% vs 16%; P aphthous stomatitis (46% vs 28%; P = .002) compared with parents of control subjects. Siblings of case subjects had a higher prevalence of PFAPA (10% vs 2%; P = .04), recurrent pharyngitis (24% vs 10%; P = .03), and recurrent aphthous stomatitis (27% vs 7%; P = .003) compared with siblings of control subjects. A portion of PFAPA case subjects seems to be familial, implying an inherited genetic predisposition to the disorder and/or shared environmental exposures. First-degree relatives (parents and siblings) of patients with PFAPA have a higher prevalence of recurrent pharyngitis and aphthous stomatitis than relatives of control subjects, which suggests that these disorders represent reduced penetrance phenotypes of PFAPA. Further characterization of the genetics and inflammatory profiles of these patients and their relatives is warranted. Copyright © 2016 by the American Academy of Pediatrics.

    Characterize patterns of weight change among subjects with obesity. A retrospective observational longitudinal study of subjects with obesity was conducted using the General Electric Centricity electronic medical record database. Subjects who were ≥18 years old with BMI ≥30 kg/m2 (first defining index BMI), had no medical conditions associated with unintentional weight loss, and had ≥4 BMI measurements/year for ≥2.5 years were included and categorized into groups (stable weight: within weight loss: ≥5 to weight loss: ≥10 to weight loss: ≥15% of index BMI lost) based on weight change during 6 months following index. No interventions were considered. Patterns of weight change were then assessed for 2 years. A total of 177,743 subjects were included: 85.1% of subjects were in the stable weight, 9.3% in the modest, 2.3% in the moderate, and 3.3% in the high weight loss groups. The proportion of subjects who maintained or continued to lose weight decreased over the 2 year observation period; 11% of those with high weight loss continued to lose weight and 19% maintained their weight loss. This group had the lowest percentage of subjects who regained ≥50% of lost weight and the lowest proportion of subjects with weight cycling (defined as not continuously losing, gaining, or maintaining weight throughout the 2 year observation period relative to its beginning). This trend persisted in subgroups with class II-III obesity, pre-diabetes, and type 2 diabetes. Weight cycling and regain were commonly observed. Subjects losing the most weight during the initial period were more likely to continue losing weight.

  10. Assessing periodicity of periodic leg movements during sleep.

    Periodic leg movements (PLM) during sleep consist of involuntary periodic movements of the lower extremities. The debated functional relevance of PLM during sleep is based on correlation of clinical parameters with the PLM index (PLMI). However, periodicity in movements may not be reflected best by the PLMI. Here, an approach novel to the field of sleep research is used to reveal intrinsic periodicity in inter movement intervals (IMI) in patients with PLM. Three patient groups of 10 patients showing PLM with OSA (group 1), PLM without OSA or RLS (group 2) and PLM with RLS (group 3) are considered. Applying the "unfolding" procedure, a method developed in statistical physics, enhances or even reveals intrinsic periodicity of PLM. The degree of periodicity of PLM is assessed by fitting one-parameter distributions to the unfolded IMI distributions. Finally, it is investigated whether the shape of the IMI distributions allows to separate patients into different groups. Despite applying the unfolding procedure, periodicity is neither homogeneous within nor considerably different between the three clinically defined groups. Data-driven clustering reveals more homogeneous and better separated clusters. However, they consist of patients with heterogeneous demographic data and comorbidities, including RLS and OSA. The unfolding procedure may be necessary to enhance or reveal periodicity. Thus this method is proposed as a pre-processing step before analyzing PLM statistically. Data-driven clustering yields much more reasonable results when applied to the unfolded IMI distributions than to the original data. Despite this effort no correlation between the degree of periodicity and demographic data or comorbidities is found. However, there are indications that the nature of the periodicity might be determined by long-range interactions between LM of patients with PLM and OSA.

Conclusions: The unfolding procedure may be necessary to enhance or reveal periodicity. Thus this method is proposed as a pre-processing step before analyzing PLMS statistically. Data-driven clustering yields much more reasonable results when applied to the unfolded IMI distributions than to the original data. Despite this effort no correlation between the {em degree} of periodicity and demographic data or comorbidities was found. However, there were indications that the {em nature} of the periodicity might be determined by long-range interactions between LM of patients with PLMS and OSA.

    Periodical cicadas (Magicicada spp.) in the USA are famous for their unique prime-numbered life cycles of 13 and 17 years and their nearly perfectly synchronized mass emergences. Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average temperature during glacial periods. During the evolution of periodicity, the determinant of maturation in ancestral cicadas is hypothesized to have switched from size dependence to time (period) dependence. The selection for the prime-numbered cycles should have taken place only after the fixation of periodicity. Here, we build an individual-based model of cicadas under conditions of climatic cooling to explore the fixation of periodicity. In our model, under cold environments, extremely long juvenile stages lead to extremely low adult densities, limiting mating opportunities and favouring the evolution of synchronized emergence. Our results indicate that these changes, which were triggered by glacial cooling, could have led to the fixation of periodicity in the non-periodical ancestors.

    The aim of this study was to evaluate the performance of the recently described timed inspiratory effort (TIE) index in comparison with 4 other previously reported indices as to the weaning outcome in patients with neurologic or neuromuscular disorders. This observational prospective study included subjects undergoing weaning from mechanical ventilation. The performance of the indices was evaluated by calculation of the area under the receiver operating characteristic curves. The areas under the curve were compared using the Hanley and McNeil method. P values<.05 were considered significant. Seventy-two subjects (57±20 y old) were selected for the study. Forty-three subjects were weaned, and 21 died during the study period. The mean duration of mechanical ventilation was 22.3±19.4 d. The areas under the curve of 5 weaning predictors (TIE index, integrative weaning index, noninvasive tension-time index, maximum inspiratory pressure, and breathing frequency/tidal volume index) were significantly higher than those of the other indices. The TIE index had the largest area under the curve (0.96±0.02) in comparison with the integrative weaning index (0.82±0.05, P=.009), noninvasive tension-time index (0.80±0.05, P=.001), maximum inspiratory pressure (0.77±0.06, P=.001), and breathing frequency/tidal volume index (0.72±0.06, P=.001). In patients with neurologic or neuromuscular impairment, the TIE index had a better performance than the best weaning indices used in clinical practice. Copyright © 2015 by Daedalus Enterprises.

  5. Quasi-periodicity in relative quasi-periodic tori

    Fassò, Francesco; García-Naranjo, Luis C.; Giacobbe, Andrea

    2015-10-01

    At variance from the cases of relative equilibria and relative periodic orbits of dynamical systems with symmetry, the dynamics in relative quasi-periodic tori (namely, subsets of the phase space that project to an invariant torus of the reduced system on which the flow is quasi-periodic) is not yet completely understood. Even in the simplest situation of a free action of a compact and abelian connected group, the dynamics in a relative quasi-periodic torus is not necessarily quasi-periodic. It is known that quasi-periodicity of the unreduced dynamics is related to the reducibility of the reconstruction equation, and sufficient conditions for it are virtually known only in a perturbation context. We provide a different, though equivalent, approach to this subject, based on the hypothesis of the existence of commuting, group-invariant lifts of a set of generators of the reduced torus. Under this hypothesis, which is shown to be equivalent to the reducibility of the reconstruction equation, we give a complete description of the structure of the relative quasi-periodic torus, which is a principal torus bundle whose fibers are tori of a dimension which exceeds that of the reduced torus by at most the rank of the group. The construction can always be done in such a way that these tori have minimal dimension and carry ergodic flow.

  6. Sensibility and Subjectivity: Levinas’ Traumatic Subject

    Directory of Open Access Journals (Sweden)

    Rashmika Pandya

    2011-02-01

    Full Text Available The importance of Levinas’ notions of sensibility and subjectivity are evident in the revision of phenomenological method by current phenomenologists such as Jean-Luc Marion and Michel Henry. The criticisms of key tenants of classical phenomenology, intentionality and reduction, are of a particular note. However, there are problems with Levinas’ characterization of subjectivity as essentially sensible. In “Totality and Infinity” and “Otherwise than Being”, Levinas criticizes and recasts a traditional notion of subjectivity, particularly the notion of the subject as the first and foremost rational subject. The subject in Levinas’ works is characterized more by its sensibility and affectedness than by its capacity to reason or affect its world. Levinas ties rationality to economy and suggests an alternative notion of reason that leads to his analysis of the ethical relation as the face-to-face encounter. The ‘origin’ of the social relation is located not in our capacity to know but rather in a sensibility that is diametrically opposed to the reason understood as economy. I argue that the opposition in Levinas’ thought between reason and sensibility is problematic and essentially leads to a self-conflicted subject. In fact, it would seem that violence characterizes the subject’s self-relation and, thus, is also inscribed at the base of the social relation. Rather than overcoming a problematic tendency to dualistic thought in philosophy Levinas merely reverses traditional hierarchies of reason/emotion, subject/object and self/other.

    The paper discusses the notion of steps in indexing and reveals that the document-centered approach to indexing is prevalent and argues that the document-centered approach is problematic because it blocks out context-dependent factors in the indexing process. A domain-centered approach to indexing...... is presented as an alternative and the paper discusses how this approach includes a broader range of analyses and how it requires a new set of actions from using this approach; analysis of the domain, users and indexers. The paper concludes that the two-step procedure to indexing is insufficient to explain...... the indexing process and suggests that the domain-centered approach offers a guide for indexers that can help them manage the complexity of indexing....

    We aimed to examine sleep in shelter-analogue settings in winter to determine the subjective sensation and environmental conditions in evacuation shelters. Twelve young healthy students took part in the sleep study of two nights for seven hours from Midnight to 7 AM in the gymnasium. One night the subject used a pair of futons and on the other the subject used the emergency supplies of four blankets and a set of portable partitions. During the night, air temperature, humidity and air velocity were measured in the area around the sleeping subjects. Sleep parameters measured by actigraphy, skin temperature, microclimate temperature, rectal temperature, and the heart rates of the subjects were continuously measured and recorded during the sleeping period. The subjects completed questionnaires regarding their thermal comfort and subjective sleep before and after the sleep. The subjects felt more coldness on their head and peripheral parts of the body using the emergency blankets than the futon during the sleep. Moreover, fatigue was felt more on the lower back and lower extremities from using emergency blankets than the futon after sleep. However, the sleep efficiency index and subjective sleep evaluation by OSA questionnaire did not reveal any good correlationship. The emergency supplies should be examined for their suitability to provide comfortable and healthy sleep in the shelter-analogue settings.

  14. Period proliferation in periodic states in cyclically sheared jammed solids

    Athermal disordered systems can exhibit a remarkable response to an applied oscillatory shear: After a relatively few shearing cycles, the system falls into a configuration that had already been visited in a previous cycle. After this point the system repeats its dynamics periodically despite undergoing many particle rearrangements during each cycle. We study the behavior of orbits as we approach the jamming point in simulations of jammed particles subject to oscillatory shear at fixed pressure and zero temperature. As the pressure is lowered, we find that it becomes more common for the system to find periodic states where it takes multiple cycles before returning to a previously visited state. Thus, there is a proliferation of longer periods as the jamming point is approached.

    The glycemic index concept owes much to the dietary fiber hypothesis that fiber would reduce the rate of nutrient absorption and increase the value of carbohydrate foods in the maintenance of health and treatment of disease. However, properties and components of food other than its fiber content contribute to the glycemic and endocrine responses postprandially. The aim of the glycemic index classification of foods was therefore to assist in the physiological classification of carbohydrate foods which, it was hoped, would be of relevance in the prevention and treatment of chronic diseases such as diabetes. Over the past two decades low glycemic index diets have been reported to improve glycemic control in diabetic subjects, to reduce serum lipids in hyperlipidemic subjects and possibly to aid in weight control. In large cohort studies, low glycemic index or glycemic load diets (glycemic index multiplied by total carbohydrate) have also been associated with higher levels of high-density lipoprotein cholesterol, reduced C-reactive protein concentrations and with a decreased risk of developing diabetes and cardiovascular disease. More recently, some case-control and cohort studies have also found positive associations between the dietary glycemic index and the risk of colon, breast and other cancers. While the glycemic index concept continues to be debated and there remain inconsistencies in the data, sufficient positive findings have emerged to suggest that the glycemic index is an aspect of diet of potential importance in the treatment and prevention of chronic diseases.

    Full Text Available Leaf area index is the main sward characteristic related to the processes of light interception and competition in plant communities. The objective of this experiment was to quantify and evaluate the composition of the leaf area on tillers of marandu palisadegrass (Brachiaria brizantha cv. Marandu subjected to strategies of intermittent stocking. The experiment was carried out in Piracicaba, state of São Paulo, Brazil, from October/2004 to December/2005. Swards were grazed at 95 and 100% canopy light interception (LI to post-grazing heights of 10 and 15 cm, following a 2 ' 2 factorial arrangement with four replications in a randomised complete block design. Estimates were made of sward leaf area index, site filling, specific leaf area and the dimensionless ratio between tiller leaf area and volume (R, as well as the relative contribution of basal and aerial tillers to these variables. In early spring, values of leaf area index and specific leaf area were low when compared to the other seasons, and swards grazed at 95% LI presented higher site filling and specific leaf area than those grazed at 100% LI. This resulted in higher tillering activity and increase in leaf area index in late spring, indicating quick recovery and early return of swards grazed at 95% LI to growing conditions. Aerial tillers corresponded to an important morphological adaptation of marandu palisadegrass to increase its competitive ability. Treatment 100/10 resulted in the highest and 95/15 in the lowest R values throughout the experiment, suggesting an allometric pattern of growth of tillers during regrowth in order to compensate low tiller population and optimise the leaf area index. Grazing management practices can benefit from this knowledge by promoting ideal sward conditions to maximise and accelerate growth.O índice de área foliar é a principal característica do dossel relacionada com os processos de interceptação e competição por luz em comunidades de

    Dual antiplatelet therapy with clopidogrel plus acetylsalicylic acid (ASA) is used for the treatment of acute coronary syndrome. A combined formulation of ASA and clopidogrel has been developed to provide dosing convenience and improve adherence. This study was designed to compare the pharmacokinetic properties and safety profile of a fixed-dose combination formulation of ASA and clopidogrel with concurrent administration of each agent in healthy male Korean volunteers. This single-dose, randomized, open-label, 2-period crossover study was conducted in 64 healthy Korean volunteers. Equal numbers of eligible participants were randomly assigned to receive either the fixed-dose combination of ASA 100 mg and clopidogrel 75 mg or the free combination of each agent followed by a 7-day washout period and then administration of the alternate formulation. Serial blood samples were collected immediately before and after dosing for 24 hours. The safety profile was evaluated by using adverse events (AEs), which were assessed by physical examination, vital signs, ECGs, clinical laboratory tests, and interviews. The 2 formulations were considered to be bioequivalent if the 90% CIs for the log-transformed C(max) and AUC(0-last) values were within the predetermined range of 0.8 to 1.25. Sixty-four volunteers (mean [SD] age, 27.51 [8.15] years; weight, 68.55 [7.86] kg; height, 173.80 [5.94] cm) were enrolled, and 63 completed the study. For ASA, the 90% CIs for the geometric mean ratios of C(max) and AUC(0-last) were 0.9483 to 1.1717 and 0.9946 to 1.1020, respectively. For salicylic acid, the 90% CIs were 0.9614 to 1.0396 for C(max) and 0.9778 to 1.0163 for AUC(0-last). For clopidogrel, the 90% CIs were 0.9809 to 1.2562 for C(max) and 0.9674 to 1.2073 for AUC(0-last). Six of the 20 AEs reported were drug related: decreased hemoglobin levels (n = 2), fever (n = 1), and headache (n = 1) with the test formulation and increased alanine aminotransferase levels (n = 1) and dyspepsia (n

    Full Text Available Abstract The study provides the rationale, history and current status of the Index Medicus for the World Health Organization Eastern Mediterranean Region. The Index is unique in combining the geographic coverage of peer-reviewed health and biomedical journals (408 titles from the 22 countries of the Region. Compiling and publishing the Index coupled with a document delivery service is an integral part of the WHO Regional Office's knowledge management and sharing programme. In this paper, bibliometric indicators are presented to demonstrate the distribution of journals, articles, languages, subjects and authors as well as availability in printed and electronic formats. Two countries in the Region (Egypt and Pakistan contribute over 50% of the articles in the Index. About 90% of the articles are published in English. Epidemiology articles represent 8% of the entire Index. 15% of the journals in the Index are also indexed in MEDLINE, while 7% are indexed in EMBASE. Future developments of the Index will include covering more journals and adding other types of health and biomedical literature, including reports, theses, books and current research. The challenges and lessons learnt are discussed.

    To address the effect of fasting on laryngopharyngeal reflux disease (LPRD). A total of 22 male subjects have been recruited for this study. Subjects with vocal fold pathologies, recent history of upper respiratory tract infection or laryngeal manipulation were excluded. Demographic data included age and history of smoking. All subjects were evaluated while fasting for at least 12 h and non-fasting. By non-fasting we mean that they ate and drank during the day at their discretion with no reservation. The abstention from water and or food intake during the non-fasting period extended from few minutes to 3 h. All subjects were evaluated at the same time during the day. The evaluation consisted of a laryngeal examination and the Reflux Symptom Index (RSI). The Reflux Finding Score (RFS) was used to report on the reflux laryngeal findings. Subjects were considered to have LPRD if either the RSI or the RFS were positive (>9 RSI, >7 RFS). There was a non-significant increase in the total prevalence of LPRD while fasting compared to non-fasting (32 vs. 50 % while fasting, p value 0.361). In the RSI, the most common symptoms while non-fasting and fasting were throat clearing (64 vs. 68 %), postnasal drip (45 vs. 59 %) and globus sensation (36 vs. 50 %). The average score of all the three increased significantly while fasting. For the RFS the most common laryngeal findings in the non-fasting group versus the fasting group were erythema (77 vs. 68 %), thick endolaryngeal mucus (77 vs. 77 %) and posterior commissure hypertrophy (55 vs. 64 %). Fasting results in a nonsignificant increase in laryngopharyngeal reflux disease. The increase can be hypothetically explained on the change in eating habits and the known alterations in gastric secretions during Ramadan. Fasting subjects must be alert to the effect of LPRD on their throat and voice in particular.

    To determine glycemic, insulinemic, and satiety indices of 3 types of kefir. This study was divided into 3 phases. In phase 1, 50 g of available carbohydrate from low-fat strawberry kefir or orange kefir was tested, and in phase 2, low-fat plain kefir containing 25 g of available carbohydrates was tested for glycemic index (GI), in both cases compared with an equivalent amount of glucose. In phase 3, 1000-kJ portions of all 3 types of kefirs were compared with white bread with the same energy content to determine the insulinemic index (II) and satiety index (SI) of all 3 kefirs. In all phases, a single-meal, randomized crossover design was performed in which the test meals were given to healthy adults, 5 men and 5 women. The total incremental plasma glucose area under the curve (iAUC) for strawberry, orange, and plain kefirs was significantly lower compared with the respective high-GI control food, which was glucose solution. However, the IIs and SIs of kefir did not differ significantly from the white bread. Kefir is a low- to moderate-GI food; however, its II was high. Although kefir had higher water content, the SI of kefir was not significantly different from white bread.

    Multiple access technique is one of important techniques within medium access layer in TCP/IP protocol stack. Each network technology implements the selected access method. Priority can be implemented in those methods to differentiate services. Some internet networks are dedicated for specific purpose. Education browsing or tutorial video accesses are preferred in a library hotspot, while entertainment and sport contents could be subjects of limitation. Current solution may use IP address filter or access list. This paper proposes subjective properties of users or applications are used for priority determination in multiple access techniques. The NS-2 simulator is employed to evaluate the method. A video surveillance network using WiMAX is chosen as the object. Subjective priority is implemented on WiMAX scheduler based on traffic properties. Three different traffic sources from monitoring video: palace, park, and market are evaluated. The proposed subjective scheduler prioritizes palace monitoring video that results better quality, xx dB than the later monitoring spots.

    The glycemic index is a ranking of carbohydrate containing foods. Foods are ranked according to their immediate effect on blood sugar levels. The higher a f ood raises blood sugar, the higher its glycemic index. Scientists published the first index in 1981 when they were researching diet therapy for diabetes. This first list contained 51 foods, and the list has continued to expand, with the most recent official list containing 750 foods. Fruits, grains, dairy products, some vegetables, pastas...

    hybrids. This study was conducted in the corn hybrids demonstrative field at the Federal University of Lavras, Minas Gerais State, Brazil. In order to evaluate the plant cover a display was used that included a horizontal structure, containing holes for viewing the points with and without plant cover, the being readings performed at random and transversally to the crop lines. The phytotechnical attributes evaluated were plant height, stand, dry matter and grain production. It can be concluded that the higher plant cover index was observed for corn hybrids P 30F33, P 30F90, P 3021, STRIKE, FORT, VALENT, UFLA 2001, UFLA 2004, CO 32, D 8480, D 8420 DKB 333B, and DKB 440, proving good quality as a protective soil plant. In the period of larger occurrence of rainfall in the south of Minas Gerais state, the corn crop can minimize the effect of the erosive process. The production of dry matter was well correlated with the plant cover index, and can be used as evidence of soil protection.

    2012-02-01

    In recent years, many of the concerns surrounding the glycemic index have been addressed by methodological studies and clinical trials comparing diets carefully matched for other nutrients. These findings are reviewed together with new observational evidence for the role of the dietary glycemic index in the etiology of cardiovascular disease. The determination and classification of the glycemic index of a food product is now standardized by the International Standards Organization. Systematic studies using isoenergetic single and mixed meals have shown that glycemic index and/or glycemic load are stronger predictors of postprandial glycemia and insulinemia than carbohydrate content alone. In overweight individuals, a diet that combined modestly higher protein and lower glycemic index carbohydrates was the most effective diet for prevention of weight regain. New observational studies have reported increased risks of coronary heart disease associated with higher intakes of carbohydrates from high glycemic index foods. Epidemiological evidence has emerged linking dietary glycemic index to visceral fat and inflammatory disease mortality. There is growing recognition that replacing saturated fat with refined, high glycemic index carbohydrates increases postprandial glycemia and may be detrimental for weight control and predisposition to cardiovascular and inflammatory disease. In contrast, low glycemic index carbohydrates reduce risk.

    Full Text Available Bibliometric analyses based on citations are most often at the forefront where scientific publications are concerned. A fact often neglected is that the visibility and availability of scientific publications are basic prerequisites for future reading, citation and influence. Journal visibility can be significantly improved by providing open access and availability through popular online databases. In this study, we investigated 112 mapping science journals to determine the visibility of scientific publications in a smaller interdisciplinary field. In addition to other data, we collected data on open access, indexing, subject areas within the Web of Science and Scopus bibliographic databases and the number of journals in these databases. The coverage of mapping science journals in 14 bibliographic databases was analyzed. Only 11% of the titles from the journals analyzed were indexed in 10 or more databases. Google Scholar, Scopus, Bibliotheca Cartographica and GEOBASE include most mapping science journals, while only 19 are included in Web of Science. A comparison indicates more thorough coverage of an individual journal in Web of Science than in Scopus. Only a few mapping science journals appear in the Directory of Open Access Journals, despite the large number of open access mapping science journals available. Adding subject categories within databases does not facilitate finding mapping science journals, which are dispersed among numerous, mostly inadequate categories in the Web of Science and Scopus databases.

    2012-02-01

    A new controlled-release formulation of aceclofenac 200 mg (Clanza CR®) developed by Korea United Pharm., Inc., South Korea, for once-daily (od) dosing provides biphasic aceclofenac release consisting of immediate release of 85 mg followed by sustained release of 115 mg. Food has been known to affect the rate and extent of absorption of several drugs, in both immediate-release and controlled-release formulations. The aim of this study was to evaluate the relative bioavailability of a new controlled-release formulation of aceclofenac (200 mg od; Clanza CR®) in comparison with immediate-release aceclofenac (100 mg twice daily [bid], Airtal®) and to assess the effect of food on the pharmacokinetics of the new controlled-release aceclofenac formulation. This study was designed as a randomized, open-label, three treatment-period, crossover, single-centre study with a 1-week washout in 41 healthy adults. The three treatments consisted of immediate-release aceclofenac 100 mg bid administered under fasting conditions; controlled-release aceclofenac 200 mg od administered under fasting conditions; and controlled-release aceclofenac 200 mg od administered immediately after a standardized high-fat breakfast. Plasma concentrations of aceclofenac were determined using a high-performance liquid chromatography method. In the fasted state, the 90% confidence intervals (CIs) of the least squares geometric mean ratios (GMRs) for the area under the plasma concentration-time curve from time zero to 24 hours (AUC(24)) and the peak plasma concentration (C(max)) of aceclofenac for the controlled-release and immediate-release formulations of aceclofenac were all within the bioequivalence criteria range of 0.8-1.25. The 90% CIs of the GMRs for the AUC(24) and C(max) of aceclofenac for the controlled-release formulation of aceclofenac in the fed and fasted states were also within the bioequivalence range. Both aceclofenac formulations were well tolerated in all subjects

    2006-01-01

    During the past ten years, there has been intensive development in theoretical and experimental research of solitons in periodic media. This book provides a unique and informative account of the state-of-the-art in the field. The volume opens with a review of the existence of robust solitary pulses in systems built as a periodic concatenation of very different elements. Among the most famous examples of this type of systems are the dispersion management in fiber-optic telecommunication links, and (more recently) photonic crystals. A number of other systems belonging to the same broad class of spatially periodic strongly inhomogeneous media (such as the split-step and tandem models) have recently been identified in nonlinear optics, and transmission of solitary pulses in them was investigated in detail. Similar soliton dynamics occurs in temporal-domain counterparts of such systems, where they are subject to strong time-periodic modulation (for instance, the Feshbach-resonance management in Bose-Einstein conde...

    2014-10-01

    The primary objective of the current study was to estimate the hair toxic metal content in adults in relation to body mass index. A total of 1,229 persons including 719 women and 510 men were examined. All subjects were divided into two age groups: 1 and 2 periods of adulthood. All men and women were also subdivided into groups in relation to their values of body mass index (BMI): underweight, normal weight, overweight and obese. Hair aluminium (Al), beryllium (Be), cadmium (Cd), mercury (Hg), lead (Pb) and tin (Sn) content was evaluated using mass spectrometry with inductively coupled plasma. It has been shown that increase in body weight is accompanied by elevated hair cadmium content in women. At the same time, no significant alteration of hair cadmium concentration was observed in males. Higher values of scalp hair mercury and lead content were observed in men and women with increased body mass index independently of their age. BMI-related elevation of hair tin content was registered only in men of the first period of adulthood. A significant correlation between hair metal content and the values of BMI was observed for mercury independently of the gender of the subjects, whereas BMI values correlated significantly with hair cadmium levels in women and lead and tin levels in men. It has been also estimated that hair cadmium, mercury and lead levels in men exceed the respective values in women.

  17. Decomposing the misery index: A dynamic approach

    2014-12-01

    Full Text Available The misery index (the unweighted sum of unemployment and inflation rates was probably the first attempt to develop a single statistic to measure the level of a population’s economic malaise. In this letter, we develop a dynamic approach to decompose the misery index using two basic relations of modern macroeconomics: the expectations-augmented Phillips curve and Okun’s law. Our reformulation of the misery index is closer in spirit to Okun’s idea. However, we are able to offer an improved version of the index, mainly based on output and unemployment. Specifically, this new Okun’s index measures the level of economic discomfort as a function of three key factors: (1 the misery index in the previous period; (2 the output gap in growth rate terms; and (3 cyclical unemployment. This dynamic approach differs substantially from the standard one utilised to develop the misery index, and allow us to obtain an index with five main interesting features: (1 it focuses on output, unemployment and inflation; (2 it considers only objective variables; (3 it allows a distinction between short-run and long-run phenomena; (4 it places more importance on output and unemployment rather than inflation; and (5 it weights recessions more than expansions.

    Hedli, Laura C; Christos, Paul; Krieger, Ana C

    2012-08-01

    Periodic limb movements (PLMs) and obstructive sleep apnea (OSA) may present as overlapping conditions. This study investigated the occurrence of PLM during continuous positive airway pressure (CPAP) titration, with the hypothesis that the presence of PLM during CPAP represented "unmasking" of a coexisting sleep disorder. A total of 78 polysomnographic recordings in 39 OSA subjects with an hourly PLM index ≥5 during CPAP application were evaluated. Application of CPAP significantly improved sleep architecture without change in the PLM index when compared with baseline. The PLM indices and PLM arousal indices were linearly correlated during both nights (r = 0.553, P PLM indices at baseline had greater changes in the PLM index as compared with the sample remainder (P = 0.004). Sixteen subjects with significantly lower PLM indices at baseline required optimal CPAP levels higher than the sample average of 8.2 cm H2O (P = 0.032). These subjects also showed significantly higher median apnea-hypopnea index (AHI) at baseline than the sample remainder (74.4 events per hour [range: 24.2-124.4 events per hour] vs. 22.7 events per hour [range: 8.6-77.4 events per hour], respectively, P PLM seen during CPAP titration may be related to a concurrent sleep disorder because of "unmasking" in patients with treated OSA.

  20. Periods and Nori motives

    CERN Document Server

    Huber, Annette

    2017-01-01

    This book casts the theory of periods of algebraic varieties in the natural setting of Madhav Nori’s abelian category of mixed motives. It develops Nori’s approach to mixed motives from scratch, thereby filling an important gap in the literature, and then explains the connection of mixed motives to periods, including a detailed account of the theory of period numbers in the sense of Kontsevich-Zagier and their structural properties. Period numbers are central to number theory and algebraic geometry, and also play an important role in other fields such as mathematical physics. There are long-standing conjectures about their transcendence properties, best understood in the language of cohomology of algebraic varieties or, more generally, motives. Readers of this book will discover that Nori’s unconditional construction of an abelian category of motives (over fields embeddable into the complex numbers) is particularly well suited for this purpose. Notably, Kontsevich's formal period algebra represents a to...

    Full Text Available The purpose of the present study was to analyze the interdisciplinary relations of “Library Science and Information Science”. For this purpose the subject categories of citing and cited journals of these fields were investigated in JCR database during the period of 1987-1997 and 2003-2013, and through the comparsion of obtained results the impact of information technology on the development of “LIS” interdisciplinarity was investigated. Methedology of the research was co-citation analysis of journals in scientometrics studies. Also the research was performed using the conventional techniques of scientometrics including Bradford law, Ward hierarchical clustering approach in statistical software SPSS, and the new measure including Proximity index. Research community includes citing and cited journals of 56 “LIS” journals during 1987-1997 and 83 journals during 2003-2013 in Journals Ctiation Report (JCR database. The results showed that “LIS” has been influenced by other subject categories more than affecting them. For example, the number of journals which “LIS” cited from 1758 (in the first period has increased to 5303 (in the second period. Co-occurrence matrix of core citing and cited subject categories was analyzed, and three main clusters in the first period and seven clusters in the second period were drawn. In general, the amount and quality of co-occurrence of subject categories in clusters showed that the domain and variety of affecting and affected subject categories were expanded in the second period. Structural similarity of clusters for affecting and affected subject categories calculated. Results showed that structural similarity of clusters in the second period was %10 higher than in the first period. Also, the Structural similarity of affecting clusters of “LIS” was more than affected clusters. Assessment of difference between subject categories groups by ANOVA and Tukey Post hoc tests showed that there were

    Full Text Available BACKGROUND: Many studies have indicated that the incidence of serious diabetic complications may be reduced through strict glycemic control. A low glycemic index diet is one tool to improve insulin resistance and improve glycemic control in type 2 diabetes mellitus (T2DM. AIM: The objective was to study the effect of pseudocereals-based breakfasts (quinoa and buckwheat on glucose variations at first meal (breakfast and second meal (standardised lunch in healthy and diabetic subjects. SUBJECTS AND METHODS: Twelve healthy subjects and 12 patients with Type 2 DM (not- insulin dependent were recruited in the study. Subjects were provided with quinoa and buckwheat breakfast meals. A standardised lunch was provided 4 h after breakfast. Postprandial blood glucose response after breakfast and the second meal effect was measured in healthy and diabetic subjects. Incremental area under the curve (IAUC values for glucose was measured in response to the breakfast and lunch. The glycemic index of the 2 pseudocereals-based test breakfasts was determined. A white wheat bread (WWB was served as a reference breakfast meal. RESULTS: In post-breakfast analyses, healthy subjects showed that buckwheat meal had significantly lower IAUC values for blood glucose compared to WWB reference meal (P < 0.001 while quinoa meal showed no significance. In diabetic subjects, buckwheat and quinoa meals had significantly lower IAUC values for blood glucose compared to WWB reference meal (P < 0.001 and P < 0.05 respectively. Blood glucose concentrations started to decline gradually for the quinoa and buckwheat but not for WWB in all healthy and diabetic subjects and returned to near-fasting baseline levels by 210 min. Post-lunch analyses indicated higher IAUC for the two breakfast types in healthy and diabetic subjects. In addition, the quinoa and buckwheat breakfast meals were followed by a significantly flatter blood glucose response to the second meal for the period between 270

This extends to n-variables the work of L. Schwartz on mean-periodicity and also extends L. Ehrenpreis' work on partial differential equations with constant coefficients to arbitrary convolutors. We also answer a number of open questions about mean-periodic functions of one variable. The basic ingredient is our work on interpolation by entire functions in one and several complex variables.

  9. Computing discharge using the index velocity method

    Levesque, Victor A.; Oberg, Kevin A.

    2012-01-01

    Application of the index velocity method for computing continuous records of discharge has become increasingly common, especially since the introduction of low-cost acoustic Doppler velocity meters (ADVMs) in 1997. Presently (2011), the index velocity method is being used to compute discharge records for approximately 470 gaging stations operated and maintained by the U.S. Geological Survey. The purpose of this report is to document and describe techniques for computing discharge records using the index velocity method. Computing discharge using the index velocity method differs from the traditional stage-discharge method by separating velocity and area into two ratings—the index velocity rating and the stage-area rating. The outputs from each of these ratings, mean channel velocity (V) and cross-sectional area (A), are then multiplied together to compute a discharge. For the index velocity method, V is a function of such parameters as streamwise velocity, stage, cross-stream velocity, and velocity head, and A is a function of stage and cross-section shape. The index velocity method can be used at locations where stage-discharge methods are used, but it is especially appropriate when more than one specific discharge can be measured for a specific stage. After the ADVM is selected, installed, and configured, the stage-area rating and the index velocity rating must be developed. A standard cross section is identified and surveyed in order to develop the stage-area rating. The standard cross section should be surveyed every year for the first 3 years of operation and thereafter at a lesser frequency, depending on the susceptibility of the cross section to change. Periodic measurements of discharge are used to calibrate and validate the index rating for the range of conditions experienced at the gaging station. Data from discharge measurements, ADVMs, and stage sensors are compiled for index-rating analysis. Index ratings are developed by means of regression

    Full Text Available The contribution of modern science to the progress of civilization is immeasurable. Even its tendency toward exclusive concentration on the objective world has had salutary effects of great value. Modern science has wiped away much that was merely superstitious or speculative. Its rejection of unfounded opinions and prejudices has helped the thinking mind question conventional beliefs, shed preferences and prejudices, and challenge established authority. But modern systems thinking inherited from natural science is the suppression of the subjective dimension of reality. Many complex systems are an attempt to define and represent all subjective experience in physical terms. The modern man has a bias towards objectivity. The powerful influence of sense impressions on his mind and thinking makes him ignore the subjective experience and consider only objective facts as a valid, legitimate and representation of reality. Observing objective factors that are physical is easier than observing subjective factors that are subtle. The mechanistic view of reality has led to the rejection of the role of the individual in social development as insignificant. The individuals determine the development of society. Their social power has its roots both in subjective factors and objective factors. Economy, politics, society, and culture are inseparable dimensions of a single integrated reality. Subject and object constitute an integrated whole. The mind sees them as separate and independent. Or it views one as completely subordinate to the other. Unbiased approach to the study of all human experiences may prove that subject and object are interdependent dimensions or elements of reality.

    The rapid growth of biomedical literature is evident in the increasing size of the MEDLINE research database. Medical Subject Headings (MeSH), a controlled set of keywords, are used to index all the citations contained in the database to facilitate search and retrieval. This volume of citations calls for efficient tools to assist indexers at the US National Library of Medicine (NLM). Currently, the Medical Text Indexer (MTI) system provides assistance by recommending MeSH terms based on the title and abstract of an article using a combination of distributional and vocabulary-based methods. In this paper, we evaluate a novel approach toward indexer assistance by using nearest neighbor classification in combination with Reflective Random Indexing (RRI), a scalable alternative to the established methods of distributional semantics. On a test set provided by the NLM, our approach significantly outperforms the MTI system, suggesting that the RRI approach would make a useful addition to the current methodologies.

    Townsend, J. C.; Cronin, J. P.

    1977-01-01

    A coronary heart disease index was developed from longitudinal ECG (LCG) tracings to serve as a cardiac health measure in studies of working and, essentially, asymptomatic populations, such as pilots and executives. For a given subject, the index consisted of a composite score based on the presence of LCG aberrations and weighted values previously assigned to them. The index was validated by correlating it with the known presence or absence of CHD as determined by a complete physical examination, including treadmill, resting ECG, and risk factor information. The validating sample consisted of 111 subjects drawn by a stratified-random procedure from 5000 available case histories. The CHD index was found to be significantly more valid as a sole indicator of CHD than the LCG without the use of the index. The index consistently produced higher validity coefficients in identifying CHD than did treadmill testing, resting ECG, or risk factor analysis.

  13. Periodicity in magmatic systems

    Caricchi, Luca

    2016-04-01

    Magmatic systems show periodicity in productivity, magma chemistry and dynamics of volcanic eruptions. The timescales over which such parameters change are highly variable and ranges between several tens of millions of years down to few hundredths of thousands years. While magmatic activity appears modulated at various frequencies, the lifetime of single volcanic systems, the duration of emplacement of single plutons, or the timespan over which a given volcanic region is active, appear to last for distinct but characteristic periods of time. Hundredths of thousands of years is a typical number for the range of zircon crystallisation ages in the products of large eruptions or for the lifetime of single plutons, while activity in volcanic regions or the duration of emplacement of crustal batholiths appears to last up to about 10 Ma. Several mechanisms such as variable magma productivity in the mantle, delamination, thermal and mechanical maturation of the crust have been proposed to modulate magmatic activity. All these processes indeed contribute to modulate the periodicity of magmatic activity, but because certain timescales are recurrent, some fundamental processes must play a fundamental role in regulating the "tempo" of magmatism. Are transitions of behaviour finally the product of major changes in mantle dynamics or is the crust the plays the pivotal role in modulating periodic variations observed in magmatic systems? In this contribution I will provide an overview of existing data on periodicity of magmatic systems and use thermal modelling to show that periodic variations of magma chemistry and the physical properties of magmas are an inexorable consequence of the evolution of the thermal budget of magmatic systems. I hope to trigger discussion and collaborations between experts of geodynamics and magmatism to establish relationships between periodicity, mantle and crustal processes.

    Objective: The aim of this study was to investigate trajectories of sleep quality and associations with mood in the perinatal period. Although it is commonly accepted that subjective sleep quality declines during pregnancy and the transition to parenthood, some women may follow qualitatively distinct trajectories. Design, Setting, and Participants: Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Data were collected from 293 women at four time points: during early pregnancy, at Time 1 (T1; sleep quality throughout the perinatal period. Results: Four trajectory groups were identified, including patterns defined by high sleep quality throughout (21.5%), mild decrease in sleep quality (59.5%), significant decrease in sleep quality (12.3%) and a group with poor sleep quality throughout (6.7%). Women who had the worst sleep quality at Time 1 and those who experienced significant increases in sleep problems throughout pregnancy were also the groups who reported the highest levels of anxiety and depressive symptoms in early pregnancy and the lowest levels of social support. After controlling for covariates, the groups with worst subjective sleep quality during pregnancy were also the most likely to experience high symptoms of depression in the postpartum period. Conclusions: Most of the women in our sample reported mild sleep disturbances through the perinatal period. A subgroup of women reported a significant decline in sleep quality from early to late pregnancy and another reported poor subjective sleep quality throughout pregnancy; these groups had the greatest risk of experiencing high symptoms of depression in the postpartum period.

    Many methods are used to track patient exposure during acquisition of plain film radiographs. A uniform international standard would aid this process. To evaluate and describe a new, simple quality-assurance method for monitoring patient exposure. This method uses the ''exposure index'' and the ''deviation index,'' recently developed by the International Electrotechnical Commission (IEC) and American Association of Physicists in Medicine (AAPM). The deviation index measures variation from an ideal target exposure index value. Our objective was to determine whether the exposure index and the deviation index can be used to monitor and control exposure drift over time. Our Agfa workstation automatically keeps a record of the exposure index for every patient. The exposure index and deviation index were calculated on 1,884 consecutive neonatal chest images. Exposure of a neonatal chest phantom was performed as a control. Acquisition of the exposure index and calculation of the deviation index was easily achieved. The weekly mean exposure index of the phantom and the patients was stable and showed <10% change during the study, indicating no exposure drift during the study period. The exposure index is an excellent tool to monitor the consistency of patient exposures. It does not indicate the exposure value used, but is an index to track compliance with a pre-determined target exposure. (orig.)

    Dietary interventions with a low glycemic index have shown to be successful for the prevention and therapy of the metabolic syndrome. In the present study, we investigated the postprandial metabolic response at rest and during physical activity the low glycemic carbohydrate isomaltulose (Palatinose™) intake compared with a conventional carbohydrate (glucose syrup/sucrose [glc/suc]) with a higher glycemic index. Twenty overweight or obese men (32-64 y old) with the metabolic syndrome and insulin resistance were enrolled in this double-blinded, randomized, cross-over study. In the morning, a breakfast consisting of a 250-mL drink and 140 g of cookies containing in a total of 50 g of Palatinose™ or glc/suc was consumed. Two hours after breakfast, subjects exercised at moderate intensity on a treadmill for 30 min. Thereafter, subjects ingested a standardized lunch consisting of a 250-mL drink with 10% Palatinose™ or glc/suc, mini pizzas, and an apple. Blood levels of glucose and insulin were measured and the postprandial substrate metabolism was determined. The glycemic and insulinemic responses were considerably lower after the ingestion of Palatinose™ (incremental area under the curve, P fat oxidation was significantly higher with Palatinose™ from breakfast to the beginning of lunch including the exercise and postexercise periods (P Fat oxidation with Palatinose™ was numerically higher throughout the entire examination period (P = 0.09). In obese subjects with insulin resistance and the metabolic syndrome, the partial substitution of carbohydrates with a higher glycemic index in foods and drinks by Palatinose™ resulted in greater postprandial fat oxidation at rest and during physical activity. It is hypothesized that this increased fat oxidation may confer further benefits for long-term weight management and for an improvement in metabolic risk factors. Copyright © 2012 Elsevier Inc.

    Whether lateralized periodic discharges (LPDs) represent ictal or interictal phenomena, and even the circumstances in which they may represent one or the other, remains highly controversial. Lateralized periodic discharges are, however, widely accepted as being ictal when they are time-locked to clinically apparent symptoms. We sought to investigate the characteristics of "ictal" lateralized periodic discharges (ILPDs) defined by time-locked clinical symptoms in order to explore the utility of using this definition to dichotomize LPDs into "ictal" and "nonictal" categories. Our archive of all continuous EEG (cEEG) reports of adult inpatients undergoing prolonged EEG monitoring for nonelective indications between 2007 and 2011 was searched to identify all reports describing LPDs. Lateralized periodic discharges were considered ILPDs when they were reported as being consistently time-locked to clinical symptoms; LPDs lacking a clear time-locked correlate were considered to be "nonictal" lateralized periodic discharges (NILPDs). Patient charts and available neuroimaging studies were also reviewed. Neurophysiologic localization of LPDs, imaging findings, presence of seizures, discharge outcomes, and other demographic factors were compared between patients with ILPDs and those with NILPDs. p-Values were adjusted for false discovery rate (FDR). One thousand four hundred fifty-two patients underwent cEEG monitoring at our institution between 2007 and 2011. Lateralized periodic discharges were reported in 90 patients, 10 of whom met criteria for ILPDs. Nine of the patients with ILPDs demonstrated motor symptoms, and the remaining patient experienced stereotyped sensory symptoms. Ictal lateralized periodic discharges had significantly increased odds for involving central head regions (odds ratio [OR]=11; 95% confidence interval [CI]=2.16-62.6; p=0.018, FDR adjusted), with a trend towards higher proportion of lesions involving the primary sensorimotor cortex (p=0.09, FDR

    Full Text Available Introduction: Dolutegravir (DTG is an HIV integrase strand transfer inhibitor approved for use in combination with other antiretrovirals for the treatment of HIV-infection in adults and adolescents. Metformin is a drug frequently used in diabetic HIV-infected patients, which requires titration to optimize dosing. In vitro, DTG inhibits organic cation transporter 2 (OCT2 and multidrug and toxin extrusion transporter 1 (MATE 1 which are known to be involved in the disposition of metformin. The objective of this study was to assess the drug interaction between DTG and metformin. Materials and Methods: This was an open-label, parallel-group, three-period crossover study in healthy adult subjects. Eligible subjects were enrolled into one of the two treatment cohorts (15 subjects/cohort. Subjects received metformin 500 mg q12h for 5 days in Period 1; metformin 500 mg q12h plus DTG 50 mg q24h (Cohort 1 or 50 mg q12h (Cohort 2 for 7 days in Period 2; and metformin 500 mg q12h for 10 days in Period 3. There were no washout periods between treatments. All doses of study drug were taken with a moderate-fat meal. Serial plasma PK samples and safety assessments were obtained throughout the study. Non-compartmental PK analysis was performed and geometric least squares (GLS mean ratios and 90% confidence intervals (CI were generated by the mixed effect model for within-subject treatment comparisons for each cohort. Results: Fourteen and thirteen subjects completed study in Cohort 1 and Cohort 2, respectively. Plasma exposures of metformin were significantly increased when co-administered with DTG (Table 1.There were no apparent changes in metformin half-life and tmax. Increased metformin plasma exposure returned to normal levels observed in Period 1 after DTG was discontinued in Period 3. No Grade 3 or 4 adverse events (AEs, deaths or serious AEs were reported during the study. Most frequently reported drug-related AEs were headache (9, loose stools (8, and

    The objective of this paper is to assess the role of conventional and high-frequency ultrasound in the evaluation of the depth of cutaneous skin cancer. The study was performed on 46 subjects, divided into 3 categories, according to their skin pathology [basal cell carcinoma (BCC), 18 subjects; superficial spreading melanoma (SSM), 8 subjects; nodular melanoma (NM), 20 subjects]. Conventional and high-frequency ultrasonographic measurements were performed in order to assess the thickness of the tumors and the vascularization degree. We compared the mean values of the tumoral thickness obtained by using ultrasound (ultrasonographic depth index) with the histological depth index, obtained after performing histological sections stained with hematoxylin-eosin, and specific monoclonal antibodies in case of pigmented tumors. We established a correlation index between the histological and ultrasonographic values of the tumoral thickness. We found a strong correlation between the ultrasonographic index (measured by high-frequency sonography) and the histological index for nodular BCC (correlation of 98.4 %), NM subjects (correlation of 98.4 %), and SSM subjects (correlation of 99.4 %). An increase of the blood supply was noticed in nodular lesions only. Ultrasonography allows a very accurate assessment of skin cancer. The ultrasonographic depth index can be considered an objective, non-invasive marker for cutaneous tumors, comparable to the histological one, with a very good sensitivity (98-99 %).

    such as concepts, aboutness, topic, isness and ofness are also briefly presented. The conclusion is that the most fruitful way of defining “subject” (of a document) is the documents informative or epistemological potentials, that is, the documents potentials of informing users and advance the development......This article presents and discuss the concept “subject” or subject matter (of documents) as it has been examined in library and information science (LIS) for more than 100 years. Different theoretical positions are outlined and it is found that the most important distinction is between document......-oriented views versus request-oriented views. The document-oriented view conceive subject as something inherent in documents, whereas the request-oriented view (or the policy based view) understand subject as an attribution made to documents in order to facilitate certain uses of them.

    Both natural and artificial small-scale swimmers may often self-propel in environments subject to complex geometrical constraints. While most past theoretical work on low-Reynolds number locomotion addressed idealised geometrical situations, not much is known on the motion of swimmers in heterogeneous environments. As a first theoretical model, we investigate numerically the behaviour of a single spherical micro-swimmer located in an infinite, periodic body-centred cubic lattice consisting of rigid inert spheres of the same size as the swimmer. Running a large number of simulations we uncover the phase diagram of possible trajectories as a function of the strength of the swimming actuation and the packing density of the lattice. We then use hydrodynamic theory to rationalise our computational results and show in particular how the far-field nature of the swimmer (pusher versus puller) governs even the behaviour at high volume fractions.

  11. Science of the subjective.

    Science.gov (United States)

    Jahn, R G; Dunne, B J

    2007-01-01

    Over the greater portion of its long scholarly history, the particular form of human observation, reasoning, and technical deployment we properly term "science" has relied at least as much on subjective experience and inspiration as it has on objective experiments and theories. Only over the past few centuries has subjectivity been progressively excluded from the practice of science, leaving an essentially secular analytical paradigm. Quite recently, however, a compounding constellation of newly inexplicable physical evidence, coupled with a growing scholarly interest in the nature and capability of human consciousness, are beginning to suggest that this sterilization of science may have been excessive and could ultimately limit its epistemological reach and cultural relevance. In particular, an array of demonstrable consciousness-related anomalous physical phenomena, a persistent pattern of biological and medical anomalies, systematic studies of mind/brain relationships and the mechanics of human creativity, and a burgeoning catalogue of human factors effects within contemporary information processing technologies, all display empirical correlations with subjective aspects that greatly complicate, and in many cases preclude, their comprehension on strictly objective grounds. However, any disciplined re-admission of subjective elements into rigorous scientific methodology will hinge on the precision with which they can be defined, measured, and represented, and on the resilience of established scientific techniques to their inclusion. For example, any neo-subjective science, while retaining the logical rigor, empirical/theoretical dialogue, and cultural purpose of its rigidly objective predecessor, would have the following requirements: acknowledgment of a proactive role for human consciousness; more explicit and profound use of interdisciplinary metaphors; more generous interpretations of measurability, replicability, and resonance; a reduction of ontological

    It is becoming increasingly clear that adaptations, initiated by exercise, can be amplified or reduced by nutrition. Various methods have been discussed to optimize training adaptations and some of these methods have been subject to extensive study. To date, most methods have focused on skeletal muscle, but it is important to note that training effects also include adaptations in other tissues (e.g., brain, vasculature), improvements in the absorptive capacity of the intestine, increases in t...

We survey both concept-based and content-based access by computers and by indexers/catalogers respectively, as well as issues of interoperability, database and indexer consistency, and cataloging standards. The authors, both of whom are trained art historians, question attempts to mystify fine art subject matter by the creation of clever library science systems that are executed by the naive. Only when trained art historians and knowledgeable catalogers are finally responsible for providing subject access to works of art, will true interoperability and consistency happen.

    Acetic acid (AcOH), a main component of vinegar, recently was found to suppress body fat accumulation in animal studies. Hence we investigated the effects of vinegar intake on the reduction of body fat mass in obese Japanese in a double-blind trial. The subjects were randomly assigned to three groups of similar body weight, body mass index (BMI), and waist circumference. During the 12-week treatment period, the subjects in each group ingested 500 ml daily of a beverage containing either 15 ml of vinegar (750 mg AcOH), 30 ml of vinegar (1,500 mg AcOH), or 0 ml of vinegar (0 mg AcOH, placebo). Body weight, BMI, visceral fat area, waist circumference, and serum triglyceride levels were significantly lower in both vinegar intake groups than in the placebo group. In conclusion, daily intake of vinegar might be useful in the prevention of metabolic syndrome by reducing obesity.
