Eating behaviors and eating disorders symptomatology in nutrition students / Conductas alimentarias y sintomatología de trastornos del comportamiento alimentario en estudiantes de nutrición

Abstract. Eating disorders are psychopathological problems that currently are becoming important due to its increased incidence in certain population groups. The objective of this study was to analyze eating behaviors and eating disorders symptomatology in nutrition students from a public university of the east of State of Mexico. A battery of tests was applied to 182 students (157 women and 25 men) with an average age of 20.5 years (SD = 2.72). Results showed 8.8% of participants with eating disorders symptomatology, finding independence with the body mass index; however, with the fat percentage we found significant differences. We found body dissatisfaction in 33.51%, although compensatory behaviors were not a predominant factor in this group, however, findings shows latent risk that is increasing by the socio-cultural influence of the body aesthetic model and affect body dissatisfaction, and changes in eating behavior, despite in his academic training students acquired theoretical knowledge about this psychopathologies. Key words: Eating disorders, eating behavior, nutrition students, risk behaviors, risk group. Resumen.

Interview Protocols to Facilitate Human Intelligence Sources' Recollections of Meetings

Summary Two experiments tested mnemonics for enhancing memory for family meeting occurrences and details. Experiment 1 tested a set of seven mnemonics to facilitate recollections of family meeting occurrences. Mnemonics helped respondents report 70% more event occurrences than were reported during unaided free recall. Experiment 2 tested (i) a revised set of mnemonics to facilitate recollections of family meeting occurrences and (ii) a version of the cognitive interview to facilitate recollections of event details. Similar to Experiment 1, the revised set of mnemonics helped respondents recall double the number of events recalled during unaided free recall. For event details, when compared with a control interview, the cognitive interview elicited more than twice as many person, conversation, action, and setting details. The mnemonics used in these experiments are relatively easy to modify and implement in intelligence-gathering interviews with human intelligence sources. Copyright © 2014 John Wiley & Sons, Ltd.
Mechanism of free fatty acid-induced insulin resistance in humans.

To examine the mechanism by which lipids cause insulin resistance in humans, skeletal muscle glycogen and glucose-6-phosphate concentrations were measured every 15 min by simultaneous 13C and 31P nuclear magnetic resonance spectroscopy in nine healthy subjects in the presence of low (0.18 +/- 0.02 mM [mean +/- SEM]; control) or high (1.93 +/- 0.04 mM; lipid infusion) plasma free fatty acid levels under euglycemic (approximately 5.2 mM) hyperinsulinemic (approximately 400 pM) clamp conditions for 6 h. During the initial 3.5 h of the clamp the rate of whole-body glucose uptake was not affected by lipid infusion, but it then decreased continuously to be approximately 46% of control values after 6 h (P < 0.00001). Augmented lipid oxidation was accompanied by a approximately 40% reduction of oxidative glucose metabolism starting during the third hour of lipid infusion (P < 0.05). Rates of muscle glycogen synthesis were similar during the first 3 h of lipid and control infusion, but thereafter decreased to approximately 50% of control values (4.0 +/- 1.0 vs. 9.3 +/- 1.6 mumol/[kg.min], P < 0.05). Reduction of muscle glycogen synthesis by elevated plasma free fatty acids was preceded by a fall of muscle glucose-6-phosphate concentrations starting at approximately 1.5 h (195 +/- 25 vs. control: 237 +/- 26 mM; P < 0.01). Therefore in contrast to the originally postulated mechanism in which free fatty acids were thought to inhibit insulin-stimulated glucose uptake in muscle through initial inhibition of pyruvate dehydrogenase these results demonstrate that free fatty acids induce insulin resistance in humans by initial inhibition of glucose transport/phosphorylation which is then followed by an approximately 50% reduction in both the rate of muscle glycogen synthesis and glucose oxidation.
Improved modeling accuracy of thick metal passive SiGe/BiCMOS components for UWB using ADS momentum

This paper demonstrates the use of ADS Momentum to model spiral and straight line inductors for ultra wide band (UWB) applications over a silicon substrate. The main focus is on the improvements in the most recent version of the Advanced-Design System (ADS 2003C), which employs a new algorithm to model metal thickness. Results for two different inductor topologies show the increased accuracy of using a thick metal approach, versus that of sheet conductors, when compared to measured test site data.
Pharmacological models in Alzheimer's disease research

Wider use of pharmacological models would facilitate the development of new drugs for Alzheimer's disease (AD), The two main models currently used are based on the cholinergic and glutamatergic hypotheses of AD, Although they lead to some of the attention and memory impairment observed in AD, they do not fully reproduce the AD pattern. The few studies that used a combination modeling approach, ie, the simultaneous administration of several drugs with the aim of impairing several neurotransmitters or different aspects of a single system, have reported no or marginal cumulative effect. On the basis of current understanding of glutamate and acetylcholine involvement in AD pathophysiology, we suggest that models using selective muscarinic-1 (M1) receptor blockers would better mimic the status of the cholinergic system in AD, This kind of model might be suitable for the assessment of drugs that do not act directly on the cholinergic system.

Both mature miR-17-5p and passenger strand miR-17-3p target TIMP3 and induce prostate tumor growth and invasion

MicroRNAs (miRNA) precursor (pre-miRNA) molecules can be processed to release a miRNA/miRNA* duplex. In the canonical model of miRNA biogenesis, one strand of the duplex is thought to be the biologically active miRNA, whereas the other strand is thought to be inactive and degraded as a carrier or passenger strand called miRNA* (miRNA star). However, recent studies have revealed that miRNA* strands frequently play roles in the regulatory networks of miRNA target molecules. Our recent study indicated that miR-17 transgenic mice could abundantly express both the mature miR-17-5p and the passenger strand miR-17-3p. Here, we showed that miR-17 enhanced prostate tumor growth and invasion by increasing tumor cell proliferation, colony formation, cell survival and invasion. miRNA target analysis showed that both miR-17-5p and miR-17-3p repressed TIMP metallopeptidase inhibitor 3 (TIMP3) expression. Silencing with small interfering RNA against TIMP3 promoted cell survival and invasion. Ectopic expression of TIMP3 decreased cell invasion and cell survival. Our results demonstrated that mature miRNA can function coordinately with its passenger strand, enhancing the repressive ability of a miRNA by binding the same target. Within an intricate regulatory network, this may be among the mechanisms by which miRNA can augment their regulatory capacity.
Cogging Torque Minimization of Surface-Mounted Permanent Magnet Synchronous Machines Using Hybrid Magnet Shapes

This paper deals with the magnet pole shape design for the minimization of cogging torque in permanent magnet synchronous machines (PMSM). New shapes of permanent magnet are proposed. The magnet shape is modeled analytically by a set of stacked and well dimensioned layers relatively to the height and opening angle. The final shape of magnet is configured by using three models in view of obtaining lower magnitude of cogging torque. A 2-D exact analytical solution of magnetic field distribution taking into account the shape of magnet, the irregular mechanical thickness of air-gap and semi-closed stator slots is established. The influence of motor's parameters such as the number of stator slots per pole and per phase and PM's magnetization on cogging torque is discussed. Analytical results are validated by the static finite-element method (FEM).

Geroprotective and Radioprotective Activity of Quercetin, (-)-Epicatechin, and Ibuprofen in Drosophila melanogaster

The modulation of longevity genes and aging-associated signaling pathways using pharmacological agents is one of the potential ways to prolong the lifespan and increase the vitality of an organism. Phytochemicals flavonoids and non-steroidal anti-inflammatory drugs have a large potential as geroprotectors. The goal of the present study was to investigate the effects of long-term and short-term consumption of quercetin, (-)-epicatechin, and ibuprofen on the lifespan, resistance to stress factors (paraquat, hyperthermia, γ-radiation, and starvation), as well as age-dependent physiological parameters (locomotor activity and fecundity) of Drosophila melanogaster. The long-term treatment with quercetin and (-)-epicatechin didn't change or decreased the lifespan of males and females. In contrast, the short-term treatment with flavonoids had a beneficial effect and stimulated the resistance to paraquat and acute γ-irradiation. The short-term ibuprofen consumption had a positive effect on the lifespan of females when it was carried out at the middle age (30–40 days), and to the survival of flies under conditions of oxidative and genotoxic stresses. However, it didn't change the lifespan of males and females after the treatment during first 10 days of an imago life. Additionally, quercetin, (-)-epicatechin, and ibuprofen decreased the spontaneous locomotor activity of males, but had no effect of stimulated the physical activity and fecundity of females. Revealed quercetin, (-)-epicatechin, and ibuprofen activity can be associated with the stimulation of stress response mechanisms through the activation of pro-longevity pathways, or the induction of hormesis.
Inter-subject variability and normal limits of the SITA Standard, SITA Fast, and the Humphrey Full Threshold computerized perimetry strategies, SITA STATPAC.

PURPOSE To establish and evaluate inter-subject variability and normal threshold limits for the new SITA strategies and to compare them with those obtained with the traditional Humphrey Full Threshold algorithm. METHODS Data from 330 eyes of 330 normal subjects were collected at 10 centres in order to establish limits of normality for the new SITA strategies and thus, to make it possible to subject SITA fields to computer-assisted visual field analysis. Two visual field tests were obtained with each of the SITA Standard, SITA Fast, and the Full Threshold algorithms. RESULTS Inter-subject variance was 31% smaller with SITA Standard and 41% smaller with SITA Fast than with Full Threshold (p<0.0001). Age-dependent decrease of differential light sensitivity was also significantly smaller with both SITA algorithms than with Full Threshold (p<0.0001), 23% and 25% respectively. Mean sensitivity was somewhat higher with both SITA Standard (29.5 dB) and SITA Fast (29.9 dB) as compared to Full Threshold (28.3 dB) (p<0.0001). Normal limits were tightened between 9 to 29% at different significance levels with SITA. CONCLUSION SITA test results from eyes with normal visual fields will on average be more even from centre to mid-periphery as compared with Full Threshold fields. They will also appear slightly lighter in grey-scale representations. Because of smaller inter-subject variance, shallower depressions are needed in SITA fields for statistical and clinical significance.
Leader-member exchange, work engagement, and job performance

Purpose – The purpose of this paper is to examine the process through which leader-member exchange (LMX) is related to followers’ job performance. Integrating the literature on LMX theory and resource theories, the authors hypothesized that the positive relationship between LMX and employee job performance is sequentially mediated by job resources (autonomy, developmental opportunities, and social support) and employee work engagement. Design/methodology/approach – In total, 847 Dutch police officers filled out an online questionnaire. Multilevel structural equation modeling was used to test the hypothesized relationships and to account for the nesting of employees in teams. Findings – Employees in high-quality LMX relationships work in a more resourceful work environment (i.e. report more developmental opportunities and social support, but not more autonomy). This resourceful work environment, in turn, facilitates work engagement and job performance. Research limitations/implications – Because of the res.
Review of Image Denoising Algorithms Based on the Wavelet Transformation

 Abstract : The search for efficient image denoising methods is still a valid challenge at the crossing of functional analysis and statistics. In spite of the sophistication of the recently methods, most algorithms have not yet attained a desirable level of applicability. All the algorithms show a high outstanding Performance when the image model corresponds to the algorithm assumptions but it fails in general and create artifacts or change the main structures of the original image. De-noising of natural images corrupted by white Gaussian noise using wavelet techniques is very effective because of its ability to capture the energy of the signal in few energy transform values or coefficients. This method performs well under a number of applications because wavelet transform has the compaction property of having only a small number of large coefficients where the remaining wavelet coefficients are very small. The aim of this review paper is to examine all existing studies in the literature related to applying wavelet transformation for denoising images. However, to review various denoising algorithms using wavelet transform; those algorithms are discussed and showed how the appearance and quality of the noisy image can be improved. Algorithms such as SUREShrink, VisuShrink,BayesShrink, Bivariate shrink, Neigh Shrink and Normal shrink are presented in this paper. In the part of the experimental results, different Gaussian white noise levels in PSNR are shown.
High Dimensional Point Process System Identification: PCA and Dynamic Index Models

In a number of areas of application, system identification problems are being transformed by the unprecedented amounts of data now becoming available. Hundreds or even thousands of signals may be recorded and in areas such as communication networks and systems neuroscience this data takes the form of point processes (spike trains). These huge data dimensions are forcing a renewed interest in dimension reduction methods as traditional approaches predicated on small data dimensions fail. Here we develop for the first time a true principal components analysis for multivariate point processes as well as a dynamic index model
Systematic integration of parameterized local search into evolutionary algorithms

Application-specific, parameterized local search algorithms (PLSAs), in which optimization accuracy can be traded off with run time, arise naturally in many optimization contexts. We introduce a novel approach, called simulated heating, for systematically integrating parameterized local search into evolutionary algorithms (EAs). Using the framework of simulated heating, we investigate both static and dynamic strategies for systematically managing the tradeoff between PLSA accuracy and optimization effort. Our goal is to achieve maximum solution quality within a fixed optimization time budget. We show that the simulated heating technique better utilizes the given optimization time resources than standard hybrid methods that employ fixed parameters, and that the technique is less sensitive to these parameter settings. We apply this framework to three different optimization problems, compare our results to the standard hybrid methods, and show quantitatively that careful management of this tradeoff is necessary to achieve the full potential of an EA/PLSA combination.
Water supply changes N and P conservation in a perennial grass Leymus chinensis.

Changes in precipitation can influence soil water and nutrient availability, and thus affect plant nutrient conservation strategies. Better understanding of how nutrient conservation changes with variations in water availability is crucial for predicting the potential influence of global climate change on plant nutrient-use strategy. Here, green-leaf nitrogen (N) and phosphorus (P) concentrations, N- and P-resorption proficiency (the terminal N and P concentration in senescent leaves, NRP and PRP, respectively), and N- and P-resorption efficiency (the proportional N and P withdrawn from senescent leaves prior to abscission, NRE and PRE, respectively) of Leymus chinensis (Trin.) Tzvel. , a typical perennial grass species in northern China, were examined along a water supply gradient to explore how plant nutrient conservation responds to water change. Increasing water supply at low levels (< 9000 mL/year) increased NRP, PRP and PRE, but decreased green-leaf N concentration. It did not significantly affect green-leaf P concentration or NRE. By contrast, all N and P conservation indicators were not significantly influenced at high water supply levels (> 9000 mL/year). These results indicated that changes in water availability at low levels could affect leaf-level nutrient characteristics, especially for the species in semiarid ecosystems. Therefore, global changes in precipitation may pose effects on plant nutrient economy, and thus on nutrient cycling in the plant-soil systems.
Pravastatin prevents steroid-induced osteonecrosis in rats by suppressing PPARγ expression and activating Wnt signaling pathway

Steroid-induced osteonecrosis of the femoral head (steroid-induced ONFH) is characterized by increase of intraosseous pressure because of lipid metabolism disturbance such as elevation of adipogenesis and fat cell hypertrophy in the bone marrow, subsequently leading to disturbances of coagulation-fibrinolysis system in the femoral head and finally resulting in bone ischemia. Pravastatin has been demonstrated to be useful in preventing steroid-induced ONFH in animal models. However, its exact mechanisms acting on this disease have not been fully elucidated. To address this problem, steroid-induced ONFH rat model was constructed to evaluate the effects of pravastatin treatment on the osteonecrotic changes and repair processes. Then, Micro-CT-based micro-angiography was performed to assess the effects of pravastatin treatment on vascularization. In addition, serum lipid levels were detected by haematological examination. After that, the expression of peroxisome proliferator-activated receptor gamma (PPARγ), Wnt3a, low density lipoprotein receptor-related protein 5 (LRP5), β-catenin and runt-related transcription factor 2 (RUNX2) at both mRNA and protein levels were further detected by immunohistochemistry, real-time quantitative PCR, and Western blot analyses. The results, the ratio of empty lacuna, adipose tissue area, and adipocyte perimeter in the bone marrow were dramatically lower in the pravastatin treatment groups than in the model group (all P < 0.05). Moreover, by micro-CT quantification, pravastatin treatment dose-dependently increased vessel volume, vessel surface, percentage of vessel volume, and vessel thickness of the femoral heads of steroid-induced ONFH rats. Importantly, pravastatin treatment could prevent steroid-induced ONFH by suppressing the expression of PPARγ, and increasing the expression of Wnt3a, LRP5, β-catenin, and RUNX2, at both mRNA and protein levels, in the femoral heads of steroid-induced ONFH rats. In conclusion, Pravastatin may prevent steroid-induced ONFH by suppressing PPARγ expression and activating Wnt signaling pathway.
