Effect of physical training on anxiety and self-esteem of obese adolescents

The decrease in physical activities plays an important role in the increased prevalence of obesity. Obese adolescents appear to experience greater dissatisfaction with their body image and be more likely to have psychological disorders. The aim of this study is to investigate the effect of a training program on anxiety and self-esteem among adolescents obese and non obese. Thus, two groups of children (obese and non obese) have followed a training program for 12 weeks. Levels of anxiety and self-esteem were evaluated before and after the training program by a questionnaire of self-esteem and state anxiety inventory. Our results showed that obese subjects are characterized by low self-esteem (p <0.001) and high anxiety (p <0.001) compared to non-obese subjects. However, after the training program, there is no significant difference between obese and non-obese for the self-esteem (p = 0.103), but for the anxiety, the obese are more anxious than the non-obese (p <0.001). Our results also showed an improvement in self-esteem (+17.9% ; p <0.001) and decreased anxiety (16.3% ; p <0.001) after the training program in obese subjects. Our study shows the importance of physical activities for obese adolescents in their identity development and emotional control. In addition, adequate nutrition associated with a moderate intensity sport is necessary for weight control.
Transistors à nanofils de silicium top-down. Application à la détection biologique.

Ce travail de these a porte sur la realisation d'un capteur d'especes biologiques en solution a partir de reseaux organises de nanofils de silicium operant sur le mode d'un transistor a effet de champ a "grille biologique". Cette nouvelle generation de biocapteurs vise a etre integree dans des systemes de detection ultrasensibles et compacts destines a des applications medicales et militaires. Nous proposons la realisation des transistors a nanofils de silicium suivant une approche dite "top-down". Cette methode, qui consiste a graver les nanofils dans une couche mince de silicium, permet un controle precis de leur positionnement, contrairement a l'approche "bottom-up", qui utilise des nanofils obtenus par croissance CVD. Ceci permet l'obtention de transistors aux caracteristiques electriques reproductibles et facilite leur integration. La premiere partie de nos travaux a ainsi concerne le design et la fabrication de transistors a nanofils de silicium suivant une approche top-down. Ce travail de developpement technologique a permis la realisation de composants que nous avons caracterises a sec puis adaptes a un fonctionnement en milieu liquide. La seconde partie de nos travaux a porte sur la realisation de mesures en solution. La validation du fonctionnement de notre transistor en mode capteur a ete demontree par le suivi de variations de pH. Notre etude a ensuite eu pour objet la mise en valeur de l'ensemble des parametres influencant les performances du capteur (choix de la tension de grille, de la force ionique, influence de la microfluidique, .), la comprehension de ces facteurs etant indispensable a la realisation de mesures biologiques fiables.
Xenazine ® ( tetrabenazine ) Tablets Depression and Suicidality

Depression and Suicidality XENAZINE can increase the risk of depression and suicidal thoughts and behavior (suicidality) in patients with Huntington’s disease. Anyone considering the use of XENAZINE must balance the risks of depression and suicidality with the clinical need for control of choreiform movements. Close observation of patients for the emergence or worsening of depression, suicidality, or unusual changes in behavior should accompany therapy. Patients, their caregivers, and families should be informed of the risk of depression and suicidality and should be instructed to report behaviors of concern promptly to the treating physician. Particular caution should be exercised in treating patients with a history of depression or prior suicide attempts or ideation, which are increased in frequency in Huntington’s disease. XENAZINE is contraindicated in patients who are actively suicidal, and in patients with untreated or inadequately treated depression. (see CONTRAINDICATIONS; WARNINGS Increased Risk of Depression and Suicidality, and PRECAUTIONS Information for Patients).
A Low-Power 2.7μW, 915-MHz Demodulator for RFID Applications

This paper presents the design of a low-power demodulator for RFID applications based on a low-current twice differential amplifier structure. The demodulator, which is an academic project, has been designed according to the technological design rules of a standard 0.5 mum, N-well CMOS process. The demodulator power supply would be taken from the RF energy with help of a voltage multiplier. From simulations results a static power consumption of 2.5 muW was deduced whereas the dynamic one was approximately 0.21 muW. The demodulator occupies an area of 243 mumtimes95.5 mum from which passive components cover an equivalent area of 74.96%
What are the core drivers in consumer adoption of NFC-based mobile payments?: A proposed research framework

The rapid evolution of mobile technologies and the increasing diffusion of smartphones have given significant opportunities for innovative companies to create new payment solutions and offer value-added services to their customers. Near Field Communication (NFC) mobile payment has been emerging as a noticeable phenomenon that can enable consumers to turn their smartphones into digital wallets. Although there has been a lot of coverage on consumer acceptance of mobile payments, there are only few researches providing guideline to interpret NFC-based mobile payments adoption. Taking into consideration of theoretical backgrounds of innovation diffusion and specific characteristics of NFC mobile payments, this study propose a research framework to provide a profound understanding of factors facilitating or impeding the adoption of NFC-based mobile payments among Taiwanese consumers. This study expects that intention to adopt NFC mobile payments is affected by product-related factors (perceived usefulness, perceived ease of use, compatibility, perceived security and privacy risk, trialability, perceived cost of use and additional value of NFC mobile payment), trust-based factors, personal-related factors (personal innovativeness in new technologies, absorptive capacity), and attractiveness of alternatives. This study will be able to advance literature on innovation adoption and facilitate technology marketers in NFC mobile payments. It provides a useful guideline to help researchers investigate of issues related to NFC mobile payments. It also bring some managerial implications by assisting relevant parties in NFC mobile payments ecosystem such as mobile network operators, card issuers, payment processing institutions, bank decision makers and merchants when devising their business strategies and marketing campaigns to fac
A Robust Collaborative Recommendation Algorithm Incorporating Trustworthy Neighborhood Model

The conventional collaborative recommendation algorithms are quite vulnerable to user profile injection attacks. To solve this problem, in this paper we propose a robust collaborative recommendation algorithm incorporating trustworthy neighborhood model. Firstly, we present a method to calculate the users’ degree of suspicion based on the user-item ratings data using the theory of entropy and the idea of density-based local outlier factor. Based on it, we measure the user’s trust attributes from different angles by introducing the source credibility theory and propose a multidimensional trust model incorporating users’ degree of suspicion. Then we propose a trustworthy neighborhood model by combining the baseline estimate approach with the multidimensional trust model. Finally, we devise a robust collaborative recommendation algorithm to provide more accurate recommendation for the target user by integrating the M-estimator based matrix factorization approach and the trustworthy neighborhood model. Experimental results on the MovieLens dataset show that the proposed algorithm has better robustness in comparison with the existing collaborative recommendation algorithms.
Can Baby Organs Be Donated in All Forensic Cases? Proposed Guidelines for Organ Donation from Infants Under Medical Examiner Jurisdiction

Donated organs from babies are desperately needed for transplantation into sick and dying children. Categories of infant death subject to medicolegal death investigation are proposed and discussed, with a rationale for decision making by medical examiners and their colleagues. Appropriate caution is warranted in some instances with investigation for possible criminal intent emphasized. Mutual cooperation with all parties must be fostered to assure organ donation from infants whenever possible.
Separate encoding of identity and similarity of complex familiar odors in piriform cortex

Piriform cortical circuits are hypothesized to form perceptions from responses to specific odorant features, but the anterior piriform cortex (aPCX) and posterior piriform cortex (pPCX) differ markedly in their anatomical organization, differences that could lead to distinct roles in odor encoding. Here, we tested whether experience with a complex odorant mixture would modify encoding of the mixture and its components in aPCX and pPCX. Rats were exposed to an odorant mixture and its components in a go/no-go rewarded odor discrimination task. After reaching behavioral performance criterion, single-unit recordings were made from the aPCX and pPCX in these rats and in odor-naïve, control, urethane-anesthetized rats. After odor experience, aPCX neurons were more narrowly tuned to the test odorants, and there was a decorrelation in aPCX population responses to the mixture and its components, suggesting a more distinct encoding of the familiar mixture from its components. In contrast, pPCX neurons were more broadly tuned to the familiar odorants, and pPCX population responses to the mixture and its components became more highly correlated, suggesting a pPCX encoding of similarity between familiar stimuli. The results suggest aPCX and pPCX play different roles in the processing of familiar odors and are consistent with an experience-dependent encoding (perceptual learning) of synthetic odorant identity in aPCX and an experience-dependent encoding of odor similarity or odor quality in pPCX.
Dorsal Distal Radius Vascularized Pedicled Bone Grafts for Scaphoid Nonunions

Fractures of the scaphoid, particularly its proximal pole, are at risk of progressing to nonunion because of the tenuous, retrograde blood supply. The overall incidence of scaphoid fractures developing nonunion ranges from 10% to 15%, whereas proximal pole fractures of the scaphoid can have up to a 30% incidence of nonunion. Avascular necrosis of these proximal pole fractures can occur in 14% to 39% of cases. Dorsal distal radius vascularized pedicled bone grafting is an alternative to conventional measures for the treatment of displaced proximal pole fractures, established nonunions, and avascular necrosis of the proximal fragment. This graft is based on the 1,2-intercompartmental supraretinacular artery, which has reliable anatomy and predictable course between the first and second extensor compartments. The graft can be harvested and inset into the prepared fracture site using a single-incision approach. The indications, contraindications, technique, and results of treatment are reviewed and detailed.
Polysomnographic measures of nocturnal sleep in patients on chronic, intermittent daytime haemodialysis vs those with chronic kidney disease.

BACKGROUND Numerous factors probably contribute to the high prevalence of sleep problems in haemodialysis (HD) patients including metabolic changes and treatment-related factors. In contrast, the sleep problems of patients with chronic kidney disease (CKD) may be more related to psychological factors rather than the metabolic changes associated with renal disease. Thus, the objective of this study was to compare polysomnographic measures of nocturnal sleep in a group of stable patients on chronic, intermittent daytime HD and an age- and gender-matched, metabolically comparable group with CKD, and evaluate the role that quality of life (including psychological factors) and the effects of treatment may play in sleep outcomes. METHODS The sample included 16 patients on HD and eight patients with CKD all of whom were free from other significant physical and psychological morbidity. To assess for psychological, functional, family and economic responses to the disease and treatment, all subjects took the Ferrans and Powers Quality of Life Index. HD subjects received treatment three times a week and were adequately dialysed [Kt/V >1.2, equivalent to a weekly glomerular filtration rate (GFR) of 10-15 ml/min]; CKD subjects had an estimated GFR of 14.5 (+/-7.2; range 5.4-28.8) ml/min. All subjects underwent one night of laboratory-based polysomnography. Appropriate statistical procedures were used to explore group differences in sleep variables and their relationship to quality of life dimensions and the effect of treatment. RESULTS The CKD patients reported significantly poorer functional and psychological quality of life; both groups had reduced total sleep time and sleep efficiency in comparison with normative data. However, HD subjects had less rapid eye movement sleep (P = 0.032). They also had a higher brief arousal index (P = 0.000), an independent predictor of which was treatment with HD, and respiratory disturbance index (P = 0.061). Less total sleep time, increased wake after sleep onset, lower sleep efficiency, higher periodic limb movement index, and longer latencies to sleep onset and rapid eye movement sleep were also noted in the HD group. Quality of life scores did not predict sleep variables in this small sample. CONCLUSIONS The results suggest that the sleep problems of patients with CKD and those receiving chronic, intermittent daytime HD may have different aetiologies; functional and psychological factors may play a more prominent role in the former group, while intrinsic sleep disruption (arousals, apnoeas and limb movements) secondary to the effects of chronic, intermittent daytime HD may play a more significant role in the latter. The findings suggest that further exploration is warranted and that population-specific sleep-promoting interventions may be indicated.
The probabilistic behaviour of the NFD Bin Packing algorithm

In the classical one-dimensional bin-packing problem we are given a list L= =(fli, a2, a„) of numbers (items) in the interval (0,1], which must be packed into a minimum number of unit-capacity bins (i.e. bins that can contain items totalling at most 1). It is well known that this problem is NP-hard [4], and accordingly a number of approximation algorithms have been developed for its solution. Johnson et al. analysed the best-known heuristics from a worst-case point of view [6]. Their analysis of approximation rules concentrated on the derivation of worst-case bounds of the form A(L) ^x-OPT(L)+p
High-performance 1200-nm InGaAs and 1300-nm InGaAsN quantum-well lasers by metalorganic chemical vapor deposition

In this paper, we present the characteristics of high-performance strain-compensated MOCVD-grown 1200-nm InGaAs and 1300-nm InGaAsN quantum-well (QW) lasers using AsH/sub 3/ and U-Dimethylhydrazine as the group V precursors. The design of the InGaAsN QW active region utilizes an In-content of approximately 40%, which requires only approximately 0.5% N-content to realize emission wavelengths up to 1315-nm. Threshold current densities of only 65-90 A/cm/sup 2/ were realized for InGaAs QW lasers, with emission wavelength of 1170-1233 nm. Room-temperature threshold and transparency current densities of 210 and 75-80 A/cm/sup 2/, respectively, have been realized for InGaAsN QW lasers with emission wavelength of 1300-nm. Despite the utilization of the highly-strained InGaAsN QW, double-QW lasers have been realized with excellent lasing performance.

An epidemiologic study of index and family infectious mononucleosis and adult Hodgkin's disease (HD): Evidence for a specific association with EBV+ve HD in young adults

Infectious mononucleosis (IM) is an established risk factor for Hodgkin's disease (HD). A substantial minority (33%) of cases of HD have Epstein‐Barr virus (EBV) DNA within the malignant cells (are EBV+ve). It is unclear whether risk after IM applies specifically to EBV+ve HD. We report the results of a population‐based case‐control study of HD in adults (n = 408 cases of classical HD, 513 controls) aged 16–74 years; the case series included 113 EBV+ve and 243 EBV‐ve HD. Analyses compared total HD, EBV+ve HD and EBV‐ve HD with the controls and EBV+ve HD with EBV‐ve HD cases using, mainly, logistic regression. Regression analyses were adjusted for gender, age‐group and socioeconomic status, and were performed for the whole age range and separately for young (< 35 years) and old adults (≥ 35 years); formal tests of effect modification by age were included. For the young adults, reported IM in index or relative was strongly and significantly associated with EBV+ve HD when compared to controls (odds ratio [OR] = 2.94, 95% confidence interval [CI]: 1.08–7.98 and OR = 5.22, 95% CI: 2.15–12.68, respectively). These results may be interpreted as indications that late first exposure to EBV increases risk of HD, especially in young adults; this applies primarily to EBV+ve HD. © 2003 Wiley‐Liss, Inc.
A Three-Dimensional Action Plan to Raise the Quality of Care of US Correctional Health and Promote Alternatives to Incarceration.

The United States has the world’s highest incarceration rate. Nonetheless, health care provided during approximately 12 million annual incarcerations remains disconnected from the rest of the nations’ health apparatus. Care delivered to the incarcerated disproportionately impacts the poor, people of color, and those with behavioral health problems. The scope and quality of this care is inconsistent and often directed by security leadership, not health professionals. Additionally, vital information gathered in these settings is rarely used to coordinate care with community providers or consider alternatives to incarceration. To increase the quality and coordination of correctional health care, three key areas must be addressed: the funding model, the scope of services, and correctional health staff.
Potential role of tryptophan derivatives in stress responses characterized by the generation of reactive oxygen and nitrogen species

Abstract: To face physicochemical and biological stresses, living organisms evolved endogenous chemical responses based on gas exchange with the atmosphere and on formation of nitric oxide (NO•) and oxygen derivatives. The combination of these species generates a complex network of variable extension in space and time, characterized by the nature and level of the reactive oxygen (ROS) and nitrogen species (RNS) and of their organic and inorganic scavengers. Among the latter, this review focusses on natural 3‐substituted indolic structures. Tryptophan‐derived indoles are unsensitive to NO•, oxygen and superoxide anion (O2•−), but react directly with other ROS/RNS giving various derivatives, most of which have been characterized. Though the detection of some products like kynurenine and nitroderivatives can be performed in vitro and in vivo, it is more difficult for others, e.g., 1‐nitroso‐indolic compounds. In vitro chemical studies only reveal the strong likelihood of their in vivo generation and biological effects can be a sign of their transient formation. Knowing that 1‐nitrosoindoles are NO donors and nitrosating agents indicating they can thus act both as mutagens and protectors, the necessity for a thorough evaluation of indole‐containing drugs in accordance with the level of the oxidative stress in a given pathology is highlighted.
Spin Dependent Tunneling Device Utilizing the Magneto-Coulomb Effect

We investigate the magneto-Coulomb effect in a single-electron tunneling transistor (SETT) with ferromagnetic leads. This effect enables us to achieve a magnetic field control, as opposed to the conventional electrical gate control of the SETT. By utilizing the sharp magnetic switching of the ferromagnetic (FM) source and drain electrodes, the magneto-Coulomb effect can attain a large magnetoconductance (MC) change in response to the applied magnetic B-field. We analyze the effect of the B-field on the effective charge Qtilde on the island, and analytically obtain the step change DeltaQtilde at the coercive field Bc of the FM leads. We also derive the optimal biasing conditions of Vg=(nplusmn1/4)e/Cg and VdsapVth (threshold bias). Such bias conditions ensure the maximum sensitivity (dI/dQtilde) of the SETT modulation to Qtilde, and hence to the applied B-field. The magnetoconductance response of the SETT under the optimal biasing condition is numerically calculated based on the assumption of single-domain switching of the FM leads
Positron Emission Tomography: Basic Principles, New Applications, and Studies Under Anesthesia

Besides electroencephalography (EEG), positron emission tomography (PET) is one of the oldest tools for the exploration of the functioning brain. PET primarily focuses on neuronal activity and metabolism in the brain. It also has potential applications in studying the neurotransmitter function in the central nervous system. PET studies have laid the foundation for understanding the fundamental properties related to motor, sensory, and some cognitive functions in physiological and pathologic states. Brain function studies with PET, EEG, magnetic resonance imaging (MRI), and other neurotechnology tools have started shedding light on hitherto unknown aspects of brain function.
Mailed urine samples are not an effective screening approach for Chlamydia trachomatis case finding among young men

Background Frequency of testing is known to be low for sexually transmitted infections (STIs) in men aged 20–24 years. The use of mailed, home‐obtained urine specimens could increase the uptake of young men and facilitate screening programmes for the detection of asymptomatic Chlamydia trachomatis.
