Time of day - effects on motor coordination and reactive strength in elite athletes and untrained adolescents.

OBJECTIVES the issue of time-of-day effects on performance is crucial when considering the goal of reaching peak results in sport disciplines. The present study was designed to examine time-of-day effects in adolescents on motor coordination, assessed with Hirtz's battery and neuromuscular components of strength, evaluated with reactive strength tests. METHODS forty-two elite female gymnasts, aged 13.3 ± 0.5 years (Mean ± SD), were recruited for the study. Fifty healthy female students (aged 12.8 ± 1.7 years) served as the control group. All participants underwent the testing sessions over two days at two different times of day in a randomized order. RESULTS Oral temperature was measured at the two times of the day and a significant diurnal variation (p < 0.01) in both groups was found. MANOVA revealed significant group differences in the overall tests (p < 0.01). The gymnast group showed no significant differences in the coordination tests with respect to the time of day, but significant differences were observed for reactive strength as assessed with the vertical jump tests (p < 0.01). Gyamnasts attained better results in the evening in the reactive strength tests [flight time (F1.90 = 17.322 p < 0.01) and ground contact time (F1.90 = 8.372; p < 0.01) of the hopping test]. CONCLUSION the temperature effect was more evident in the reactive strength tests and orientation test, especially in the gymnast group in which this effect added to their usual training time effect. The time-since-awakening influenced coordination performances in complex tasks more than reaction strength tests in simple tasks. The main outcome of the study was that we did not observe time-of-day effects on coordination skills in elite gymnasts and in untrained adolescents. The time of day in which athletes usually trained these skills could influence these results. Key pointsThe results obtained in this study suggested that the best time to perform a particular task depends specifically on the nature of the task, the precise size of the cognitive load and the level of practice of the participants.In the field of practice, it is incumbent for coaches to organise sports selection based on reactive strength, using the morning hours for untrained adolescents, when alertness and the benefits of sleeping could improve performance. Evening hours, conversely, should be used for elite gymnasts who specifically train at that time (specific "temporal training effect"). These study results cannot give indications about the best time of the day to organize selection tests based on coordination skills.
Eyebrow Keyhole Approach in Vascular Neurosurgery

The authors review their experience in the surgery of intracranial aneurysms via an eyebrow keyhole approach. The eyebrow keyhole approach presumes a skin incision in the lateral two-thirds of the eyebrow followed by small supraorbital craniotomy (15 x 25 mm). Using this approach and an intraoperative endoscope for better visualisation of the aneurysmal neck, the authors operated on thirty-seven patients with forty intracranial aneurysms. There was no mortality, postoperative recovery was fast, and the cosmetic effect was excellent. Advantages and possibilities of this approach are discussed and results are presented. The authors recommend this approach as a minimal invasive surgery procedure in the treatment of intracranial aneurysms. When performed by experienced vascular neurosurgeons this approach is neither more difficult for the surgeon nor more dangerous for the patient than any other standard craniotomy procedure. According to the authors' present results, surgery of intracranial aneurysm via an eyebrow keyhole approach is the method of choice when performed by an experienced vascular neurosurgeon.
Effect of antihypertensive therapy on endothelial markers in newly diagnosed stage 1 hypertension: a randomized single-centre study.

OBJECTIVE This study was aimed to investigate the effects of olmesartan or nebivolol treatment on blood pressure and some endothelial function markers in newly diagnosed patients with stage 1 essential hypertension. METHODS This randomized open label study included 85 newly diagnosed patients with stage 1 hypertension (50 males, mean age: 52 ± 9 years). Blood pressure, flow mediated vasodilatation (FMD) and echocardiographic measurements of the patients were taken before and 8 weeks after the beginning of treatment with olmesartan or nebivolol. Nitric oxide, plasminogen activator inhibitor 1 (PAI-1) and C reactive protein (CRP) levels measured in serum samples before and after treatment, were compared. Basal variables that can affect the antihypertensive response were evaluated by multivariate logistic regression analysis. RESULTS The reduction observed in the systolic and diastolic blood pressures after antihypertensive treatment was significant (p<0.05). FMD was significantly improved after treatment in both nebivolol and olmesartan groups; however, there was no significant difference between nebivolol and olmesartan groups (p=0.6). While CRP and PAI-1 levels decreased, nitric oxide levels increased in both nebivolol and olmesartan treatment groups; but these changes were not statistically significant. No drug related complication was observed. CONCLUSION This study has indicated that olmesartan and nebivolol causes similar changes in blood pressure response, FMD and endothelial function biomarkers improved. These results suggest that antihypertensive treatment, independent of the medication used, is associated with endothelial function improvement.
A compact all-textile on-body SIW antenna for IoT applications

A compact all-textile on-body substrate integrated waveguide (SIW) antenna for internet of things (IoT) applications is proposed. By using the half-mode substrate integrated waveguide (HMSIW) technique, the antenna has a compact size while fully covering 5-GHz Wifi band and has a gain of 6.08 dBi at the center frequency. In order to integrate with an on-body IoT device, all components of the proposed antenna are made of textile materials and the human body effect is analyzed using the two-thirds human equivalent phantom.
Higher Prevalence of Synaesthesia in Art Students

Synaesthesia may facilitate the expression of creativity. Therefore synaesthetes may be more common in the world of creative art. To test this possibility, we used behavioural and phenomenological measures to assess the existence of grapheme–colour synaesthesia in a sample of art students (N = 99) and a control sample (N = 96). We found a prevalence of about 7% in the former and about 2% in the latter. Our findings suggest that synaesthesia may indeed be more common in art students.
The Defining Issues Test and the Four Component Model: Contributions to professional education

This article reviews studies examining the effect of professional education on ethical development. Most studies limit assessment to the measurement of moral judgement, observing that moral judgement plateaus during professional school unless an ethics intervention is present. Whereas interventions influence the shift to postconventional reasoning (the DIT P score), a more illuminating picture of change may emerge if researchers examined DIT profiles. More importantly, limiting assessment to measures of moral judgement ignores important aspects of moral functioning suggested by the Four Component Model. Assessment methods have been validated for sensitivity, reasoning, role concept and ethical implementation that could be adapted to provide individuals in a particular profession with a more complete picture of abilities needed for real-life professional practice.
Emotional Eating Scale for Children and Adolescents: Psychometric Characteristics in a Spanish Sample

The aims of this study were to validate the Emotional Eating Scale version for children (EES-C) in a Spanish population and study the differences in emotional eating among children with binge eating (BE), overeating (OE), and no episodes of disordered eating (NED). The questionnaire was completed by 199 children aged 9 to 16 years. Confirmatory factor analysis revealed five scales: eating in response to anger, anxiety, restlessness, helplessness, and depression. The EES-C showed good internal consistency and test–retest reliability, and it showed moderate relationships with measures of disordered-eating [Children's Eating Attitudes Test-26 (ChEAT-26), Questionnaire of Eating and Weight Patterns–Adolescent Version (QEWP-A)] and psychopathology (State-Trait Anxiety Inventory for Children, Children's Depression Inventory, Child Behavior Checklist). There were significant differences between the BE/NED groups (with the OE group in the middle position) in desire to eat when Anger (the girls in BE group, and the oldest children in OE group obtaining higher scores) or Helplessness were present. Eating due to Depression was higher in the older groups. Multiple regression analysis conducted showed that anxiety-trait was the best predictor of emotional eating. Results support the potential utility of the EES-C in the study of emotional eating in children and its validity in the Spanish population.
Plankton Sinking and Turbulence

Abstract : In still fluid, heavy particles tend to fall and reach, after some time, a terminal velocity determined by the balance between the pull of gravity and the viscosity of the fluid. Often,plankton cells are slightly heavier than sea water, and as a consequence they tend to sink in the water column. This sinking could then take them below the euphotic layer, arresting photosynthesis. To overcome sinking, plankton have devised various types of strategies. One is swimming,that is, an active, energy-consuming self-propulsion than can oppose gravitational sinking. Other phytoplankters can modify their buoyancy, becoming, at least for some time, positively buoyant. Others can exploit the turbulence in the mixed layer, using it to stay suspended for longer times. This latter option was discussed at length by Margalef, who associated the level of turbulence in the surface layer with the type of organisms that are environmentally favoured. The terminal velocity of spherical impurities with the same density grows with the squared radius of the falling impurity. Thus, larger plankton cells tend to sink faster than smaller ones, provided they can be approximated by a somewhat spherical shape. When the turbulence in the euphotic layer is low, Margalef argued, smaller, possibly swimming phytoplankters such as flagellates are favoured as the larger species sink more rapidly out of the euphotic zone. On the other hand, when the level of turbulence is high, larger plankton can benefit from turbulent suspension and become favoured with respect to the small ones (which feel diffusion limitation of nutrients more severely). One potential problem with this view is that it is not clear whether turbulence really favours a prolonged suspension of heavy impurities. For example, the results of an experiment by Ruiz et al apparently indicate that turbulence make heavy particles sink faster than in still fluid.
Genomic alterations in primary gastric cancers analyzed by comparative genomic hybridization and clinicopathological factors.

BACKGROUND/AIMS Genetic changes during the oncogenesis and progression of gastric cancer remain unclear. The aim of our study was to analyze chromosomal aberrations in primary gastric cancers. METHODOLOGY Using comparative genomic hybridization, we screened 47 primary gastric cancers for changes in the number of copies of DNA sequences. RESULTS Gains of chromosome arms 20q (55%), 20p (36%), 17q (32%), 19q (30%) and 16p (30%), and losses of chromosome arms 4q (40%), 17p (40%), 5q (38%), 18q (30%) and 4p (28%) were detected most frequently. In addition, a high level of amplification was observed at 3q21 (2%), 6p21 (4%), 7q31 (6%), 8q23-24 (2%), 19q12-13 (2%), and 20q13 (2%). Among these alterations, the gain of 20q was the most frequent change. We then compared these changes with clinicopathological factors and identified signet ring cell carcinomas in 6 cases. Our study demonstrated no amplification of chromosome 20q in signet ring cell carcinoma in contrast to that in the other histologic types of gastric cancer. CONCLUSIONS Our findings may be related to the morphologic and clinical features of signet ring cell carcinoma, and several oncogenes mapped on 20q may play an important role as determinants of the clinical and histologic features of gastric cancer.
CT Urography for the Diagnosis of Medullary Sponge Kidney

Background: Medullary sponge kidney (MSK) is characterized by malformation of the terminal collecting ducts and is associated with an increased risk of nephrolithiasis, nephrocalcinosis, urinary tract infections, renal acidification defects, and reduced bone density. It has been historically diagnosed with intravenous pyelography (IVP), which is falling out of favor as an imaging modality. CT urography (CTU) performed with multidetector CT (MDCT) has been shown to create images of the renal collecting system with similar detail as IVP; however, its utility in diagnosing MSK has not been defined. Case Report: We present the first 15 patients with recurrent symptomatic nephrolithiasis who were evaluated in our renal stone clinic with CTU. Four patients were diagnosed with MSK after visualization of the characteristic radiologic findings. Discussion: CTU effectively demonstrates the characteristic radiologic findings of MSK including collecting tubule dilatation, medullary nephrocalcinosis, nephrolithiasis, and medullary cysts. Dose reduction protocols can reduce radiation exposure below that associated with conventional IVP. We propose CTU be considered for the diagnosis of MSK.
Diagnosis of systemic candidiasis by latex agglutination for serum antigen

Three latex agglutination test procedures for detecting Candida antigen in human serum were compared in a retrospective study of 69 patients and 20 normal volunteers. Untreated human serum was reacted with two different latex reagents; one reagent also was reacted with serum treated with protease and heat. The test procedure with treated serum was best, detecting serum antigen in 17 of 21 patients (81%) with disseminated candidiasis. Judging by autopsy-proven cases, there was an increase in positive test results in the last 2 weeks of life. When untreated sera were tested with this reagent, only 3 (14%) of the 21 patients with disseminated candidiasis had detectable antigen in serum. A subset of these same sera was tested by a commercial latex reagent (Candida Detection System lot C001; Ramco Laboratories, Inc., Houston, Tex.) and untreated serum. Of 18 patients with disseminated candidiasis, 5 (28%) had at least one positive serum. Sera from patients with less severe clinical forms of candidiasis were usually negative regardless of the test procedure used. With one exception, sera from control patients were negative or were positive only in sera containing rheumatoid factor. Latex agglutination tests for Candida spp. in treated serum may prove to be a useful procedure for the rapid diagnosis of severe disseminated candidiasis.
Peer Relations in Children with Hyperactivity/Attention Deficit Disorder

The first two of this year's Topical Reviews provided a primarily educational perspective on the social skills problems of learning disabled children. As a compliment to that perspective, this month's Topical Review, written by two clinical psychologists, discusses the identification and treatment of social/behavioral problems in hyperactive children. As is well known, hyperactive and learning disabled children have many difficulties in common, and disturbed social/peer relationships appear to be one of them. The present review discusses the potential causes of disturbed peer relationships in these children, as well as evaluating the relative effectiveness of behavioral, pharmacological, and educational treatments for them. What is known and what needs to be known regarding the peer relationships of hyperactive children is reviewed. Hyperactive children, particularly those who are also aggressive, have serious disturbances in peer relations. Although several treatments have been investigated, no sufficient intervention has yet been discovered. Suggestions are offered for future studies of the nature, treatment, and predictive importance of these children's problems in peer relations.
On reduced complexity IIR adaptive filters

Reduced complexity IIR adaptive filters, like Laguerre adaptive filters with pole updating are being considered as an alternative to full adaptive IIR schemes. On the other hand, low complexity realizations exist that allow a better compromise between filter-order and modeling performance. We discuss, in this work, characteristics and properties of a reduced complexity IIR orthogonal realization that improve on those of the Laguerre and sub-optimal IIR counterparts. After reviewing the Laguerre and sub-optimal adaptive filters with pole updating, we introduce a reduced complexity IIR adaptive filter based on the Steiglitz-McBride method. The particular realization proposed is based on a generalized orthonormal family of functions. The Steitglitz-McBride method is discussed mainly because it can avoid the local minima problem related to direct mean squared output error minimization. Computer simulations are given to illustrate the good performance of the proposed adaptive IIR filter with respect to computational complexity and modeling capability if compared with its Laguerre counterpart.
Cellular functions of the Rap1 GTP-binding protein: a pattern emerges

Rap1 belongs to the Ras subgroup of small GTP-binding proteins. Whereas its early history has focused on its biochemical homology to Ras and the alleged functional antagonism between these two small GTPases, recent cellular evidence suggests that endogenous Rap1 plays a unique, Ras-independent role in eukaryotic cells. Activated by virtually all receptor types and second messengers, Rap1 controls adhesion-related functions such as phagocytosis, cell-cell contacts and functional activation of integrins through inside-out signalling. Whereas the precise mechanism by which its downstream effectors exert these diverse functions is unknown, Rap1 seems to fulfil the evolutionarily conserved function of patterning the eukaryotic cell, thus enabling it to respond to its environment, in particular through cytoskeletal remodelling.
A 6-Bit 1 GS/s Pipeline ADC Using Incomplete Settling With Background Sampling-Point Calibration

A 6-bit 1 GS/s single-channel pipeline ADC using an incomplete settling concept is presented. A background sampling-point calibration is proposed to adjust MDAC sampling point so that low gain and low bandwidth opamp can be utilized to conserve power. The prototype ADC in 65-nm CMOS process exhibits an INL of +0.76/ -0.68 LSB and a DNL of +0.72/ -0.68 LSB. Its ENOB is 5.25 bits at Nyquist input frequency with the conversion rate of 1 GS/s. It consumes 62 mW including calibration circuit power at 1 V supply and occupies an active chip area of 0.3 mm2.
DICKE’S SUPERRADIANCE IN ASTROPHYSICS. I. THE 21 cm LINE

We have applied the concept of superradiance introduced by Dicke in 1954 to astrophysics by extending the corresponding analysis to the magnetic dipole interaction characterizing the atomic hydrogen 21 cm line. Although it is unlikely that superradiance could take place in thermally relaxed regions and that the lack of observational evidence of masers for this transition reduces the probability of detecting superradiance, in situations where the conditions necessary for superradiance are met (close atomic spacing, high velocity coherence, population inversion, and long dephasing timescales compared to those related to coherent behavior), our results suggest that relatively low levels of population inversion over short astronomical length-scales (e.g., as compared to those required for maser amplification) can lead to the cooperative behavior required for superradiance in the interstellar medium. Given the results of our analysis, we expect the observational properties of 21 cm superradiance to be characterized by the emission of high-intensity, spatially compact, burst-like features potentially taking place over short periods ranging from minutes to days.
Study on prediction model of deep pit deformation

Elman neural network (ENN) is one of the well-known dynamic recurrent neural networks. A new self-adaptive particle swarm optimization (SPSO) was proposed to improve Elman in order to solve problems of dynamic prediction in this paper. SPSO combines ENN and form SPSONN hybrid algorithm. Based on the algorithm, a nonlinear time-varying model was established to prediction deformation of deep foundation pit. The results of an engineering case indicate that the intelligent prediction model is efficiencies in the complex underground structures.
Iris Recognition Based on DLDA

Iris feature extraction is very important for an iris recognition system. This paper focuses on iris feature extraction. In this paper we propose direct linear discriminant analysis (DLDA) which combines with wavelet transform to extract iris feature. In our method, firstly, we apply wavelet decomposition to the normalized iris image whose size is 64times256 and just choose the coefficients of the approximation part of the second level wavelet decomposition to represent the iris image because this part contains main feature of the original iris image but the size of this part is only 16times64. And then make use of DLDA to extract the iris feature from this approximation part. During classification, the Euclidean distance is applied to measure the similarity degree of two iris classes. In the end of this paper, the proposed method was tested on the second version CASIA iris database. We evaluate the performance by equal error rate (EER) which is the point that the false match rate (FMR) is equal to false non-match rate (FNMR) in valve. The experiment shows that the EER of our method is about 1.44% which is lower than other methods such as principle component analysis (PCA) and independent component analysis (ICA) etc
