Comorbidity headache and epilepsy in childhood.

RATIONALE Epilepsy and headache are both frequent in childhood. Because seizures are frequently a frightening event, other medical conditions--including headache--are often neglected not only by the patient, but also by the physician. The objective of this study was to verify the comorbidity between headache and epilepsy in childhood. METHODS This was a prospective study conducted at the pediatric epilepsy clinic of our university hospital. Fifty children with epilepsy and ability to describe their symptoms, between 5 and 18 years old, were interviewed according to a semi-structured questionnaire. The headache was classified according to the International Headache Society. The frequency of headache was compared with the findings of a control group composed by children without epilepsy, siblings of children with epilepsy. RESULTS Fifty children were evaluated, 29 boys, mean age 11 years. Twenty-three (46 %) patients presented with headache, as opposed to only 1 (2.5 %) in the control group ( p < 0.01). Ten (43.5 %) had migraine, 4 (17.4 %) had tension type headache and in 9 (39.1 %) the type of headache could not be established. In 9/23 (39 %) a temporal relationship between headache and epilepsy was present, 6 postictal and 3 preictal. There was no difference in gender, age, type of seizure and family history of headache in the groups of patients with or without headache. However, most patients with headache were older than 10 years (54.5 %) and had idiopathic epilepsy (65.2 %; p < 0.01). The headache usually started in the same year or after the diagnosis of epilepsy (95 %; p < 0.01). CONCLUSION Headache and epilepsy are a common comorbidity in childhood, and occur mostly in children older than 10 years with idiopathic epilepsy. The headache usually starts in the same year or after the diagnosis of epilepsy.
Texture classification and retrieval using random neural network model

Texture is one of the most important characteristics used in computer vision and image processing applications. A new texture classification and retrieval method is proposed for texture analysis applications. The technique makes use of the random neural network model. The main aim is to represent textures with parameters which are the random neural network weights and classify and retrieve textures using this texture definition. The network has neurons that correspond to each image pixel, and the neurons are connected according to neighboring relationship between pixels. The method is tested on images produced using the Brodatz album and texture blocks cut from remotely sensed images.
Potassium fertiliser enhances the salt-tolerance of common bean (Phaseolus vulgaris L.)

Summary Sodium chloride (NaCl) is the most abundant salt that contributes to soil salinity. The response of plants to excess NaCl is complex, involving changes in their morphology, physiology, and metabolism. Potassium (K) is not only an essential macronutrient for plant growth and productivity, but it is also a primary osmoticum for maintaining the low water potential of plant tissues. A pot experiment was conducted in the wire-house of the National Research Centre, Cairo, Egypt, during the 2010 – 2011 season, to examine the potential role of K fertiliser in alleviating the deleterious effects of NaCl-salinity on some physiological and biochemical traits of two recombinant inbred lines (RILs) of common bean (Phaseolus vulgaris L.; RIL 147 and RIL 115). The results showed that salinity levels of 25 mM (S1) and 50 mM NaCl (S2) caused significant decreases in the numbers of pods per plant, the fresh weight (FW) and dry weight (DW) of pods per plant, shoot DW per plant, as well as in the level of photosynthetic pigments, compared to plants irrigated with tap water (S0). A dose of 150 mg K2O kg–1 soil (K2) mitigated these harmful effects of salinity on common bean yield and on the content of photosynthetic pigments. Both salinity levels (S1 and S2) and treatment K2 caused significant increases in proline, free amino acid, and soluble carbohydrate concentrations, as well as peroxidase and polyphenol oxidase activities, relative to the corresponding control plants. In contrast, both RILs show a decrease in their phenolic compound concentrations due to salinity and/or the application of K2 compared to control plants (i.e., treatment S0K1; where K1 = 25 mg K2O kg–1 soil). The K+:Na+ ion ratio decreased significantly as the salinity level increased, and increased significantly under treatment K2. We conclude that treatment K2 mitigated the adverse effects of salinity (NaCl) through the effect of K+ ions enhancing the levels of photosynthetic pigments, anti-oxidant enzyme activities, osmoprotectant concentrations, and the K+:Na ion ratio, all of which were reflected in an improvement in plant performance.
Another contender in the arctangent race

Fast and accurate methods for computing the arctangent of a complex number x = I + jQ have been the subject of extensive study because estimating the angle /spl theta/ of a complex value has so many applications in the field of signal processing. Practitioners interested in high-speed arctangent computations typically use look-up tables where the values of I and Q specify an address in read-only memory (ROM) containing an approximation of angle /spl theta/. In this paper, another method to compute the arctangent approximation is proposed that uses neither the look-up table nor high order polynomials.
Re: Specific Antibody Levels at the Cervix During the Menstrual Cycle of Women Vaccinated With Human Papillomavirus 16 Virus-Like Particles

Background: In early-phase trials, a human papillomavirus 16 (HPV16) virus-like particle (VLP) vaccine has been shown to be well tolerated, immunogenic, and protective against HPV16 in women, most of whom were taking oral contraceptives. Previous studies have not determined whether HPV immunization results in specific antibody levels in the human genital tract or whether these levels might vary during contraceptive or ovulatory cycles. Therefore, we determined the levels of total and specific antibodies in the cervical secretions of women who had been immunized with HPV16 VLPs and examined the influence of the menstrual cycle and oral contraceptive use on these levels. Methods: Two groups of women were immunized, seven who were taking oral contraceptives and 11 who were ovulating. After seroconversion, serum and cervical secretions were collected twice weekly for 5 weeks. Total immunoglobulins (IgG and IgA) and vaccine-specific IgGs were determined by enzyme-linked immunosorbent assay. Nonparametric statistical analyses were used to determine the statistical significance of differences in IgG levels between groups, and correlations between serum- and cervical-specific IgG levels were determined by the Spearman correlation coefficient. Results: All participants developed detectable titers of anti-HPV16 VLP IgGs in their cervical secretions after immunization. The cervical titers of specific IgG and total IgGs and IgAs among participants in the contraceptive group were relatively constant throughout the contraceptive cycle. In contrast, the cervical titers of specific IgG and total IgGs and IgAs among participants in the ovulatory group varied during the menstrual cycle, being highest during the proliferative phase, decreasing approximately ninefold around ovulation, and increasing approximately threefold during the luteal phase. Serum- and cervical-specific IgG levels were correlated (r = .86) in women in the contraceptive group but not in women in the ovulatory group (r = .27). Conclusions: The relatively high titer of anti-HPV16 antibodies at the cervix is promising in terms of vaccine efficacy; however, the decrease in antibody titer around ovulation raises the possibility that the HPV16 VLP vaccine might be less effective during the peri-ovulatory phase.
Human Herpesvirus 8 Immunostaining

Human herpesvirus 8 (HHV-8) is recognized as a major causal agent of Kaposi sarcoma (KS), and it has been detected in all epidemiologic variants of KS. Until now, detection of HHV-8 in paraffin-embedded sections was done mostly by using reverse transcriptase–polymerase chain reaction. To assess the sensitivity and specificity of an anti–HHV-8 antibody and its potential usefulness for separating KS from its mimickers, we immunostained 72 KS samples and 108 samples of potential mimickers of KS with the monoclonal antibody latent nuclear antigen-1 (LNA-1; Advanced Biotechnologies, Columbia, MD). Cases of KS included all epidemiologic variants of the disease. Non-KS lesions included 34 angiosarcomas, 4 kaposiform hemangioendotheliomas, and 70 various benign vascular lesions. Immunostaining for CD31, CD34, and/or von Willebrand factor (factor VIII) also were performed in all cases. All but 1 case of KS (sensitivity, 99%) and none of the non-KS lesions (specificity, 100%) stained with the LNA-1 anti–HHV-8 antibody. The LNA-1 anti–HHV-8 antibody is a reliable marker of all variants of KS. Because KS mimickers are consistently negative for this marker, its use for diagnostic purposes is recommended.
Reproductive Traits of Hermaphroditic Muscadine Cultivars

Native muscadines ( Vitis rotundifolia Michx.) are dioecious, but muscadine vineyards are usually planted with a mixture of female plants and hermaphroditic pollenizers. Hermaphroditic cultivars are derived from either of two separate sources original hermaphroditic plants, H1 or H2. Nine hermaphroditic and two female cultivars were studied to determine their potential as pollenizers. Inﬂorescences of each cultivar were collected in the ﬁeld to evaluate the number of anthers per ﬂower, the number of pollen grains per anther, and pollen viability and germination in the main and secondary ﬂowering periods. The number of ﬂower clusters per shoot ranged from one to four with most producing two or three ﬂower clusters per shoot. The number of anthers per ﬂower varied by cultivar and cluster position, but in general was between six and eight anthers per ﬂower. ‘Noble’ showed the highest pollen grains production per anther and per ﬂower, reaching 5777 and 39,860, respectively, in the ﬁrst cluster and ‘Carlos’ produced the least amount of pollen. All cultivars that had secondary ﬂowering showed lower pollen production per anther and per ﬂower as compared with the main ﬂowering period. Optimal muscadine pollen germination media contained 50 mg · L L 1 boric acid, 145 mg · L L 1 calcium nitrate, 188 g · L L 1 sucrose, 10 g · L L 1 agar,
Dropouts on the Web: Influence of changes in respondents' interest and perceived burden during the Web survey

Dropouts in Web surveys may pose a serious threat to data quality, yet their causes are often unknown. This study aims to shed light on how respondent's motivation changes throughout the survey and how that affects dropping out. While most existing studies examine survey response at a single point in time, we try to grasp the dynamics of respondents' behavior by registering their perceptions of survey situation throughout the survey. The questionnaire consisted of an introductory part followed by 20 Web pages with several questions apiece. The pages differed in content and format of the questions, as well as in number of questions and average completion time. The order of the pages was randomized. At the end of each page, respondents were asked how interesting the questions on that page were and how much effort they invested in answering them. Changes in interest and perceived burden were analyzed for groups of respondents who dropped out at each page. The results show that interest usually decreases and perceived burden increases just before the respondent drops out. These changes in interest and burden are related to characteristics of the questions, respondents, and survey design. Respondents' tendency for dropout can be observed even before the dropout actually happens, through lower levels of interest, higher levels of effort, and higher item nonresponse in question blocks that precede the point of the dropout. Global evaluations of survey experience are not affected by overall duration of the questionnaire, but mostly by certain key moments during the questionnaire, most notably the maximum and ending levels of interest and effort. The results could help in practical work and open new paths to theoretical explanations of survey behavior.

Real-time scheduling for media processing using conditionally guaranteed budgets

In dit proefschrift behandelen we een planningsprobleem dat haar oorsprong vindt in het kosteneffectief verwerken van verschillende media door software in consumentenapparaten, zoals digitale televisies. De laatste jaren zijn er trends gaande van analoge naar digitale systemen, en van verwerking van digitale signalen door speci? eke, toepassingsgerichte hardware naar verwerking door software. Voor de verwerking van digitale media door software wordt gebruik gemaakt van krachtige programmeerbare processoren. Om te kunnen wedijveren met bestaande oplossingen is het van belang dat deze programeerbare hardware zeer kosteneffectief wordt gebruikt. Daarnaast dienen de bestaande eigenschappen van deze consumenten apparaten, zoals robuustheid, stabiliteit, en voorspelbaarheid, behouden te blijven als er software wordt gebruikt. Verder geldt dat er gelijktijdig meerdere media stromen door een consumenten apparaat verwerkt moeten kunnen worden. Deze uitdaging is binnen de onderzoekslaboratoria van Philips aangegaan in het zogenoemde Video-Quality-of-Service programma, en het werk dat in dit proefschrift beschreven wordt is binnen dat programma ontstaan. De binnen dat programma gekozen aanpak is gebaseerd op schaalbare algoritmen voor de verwerking van media, budgetten voor die algoritmen, en software dat de instelling van die algoritmen en de grootte van de budgetten aanpast tijdens de verwerking van de media. Ten behoeve van het kosteneffectief gebruik van de programmeerbare processoren zijn de budgetten krap bemeten. Dit proefschrift geeft een uitvoerige beschrijving van die aanpak, en van een model van een apparaat dat de haalbaarheid van die aanpak aantoont. Vervolgens laten we zien dat die aanpak leidt tot een probleem wanneer er gelijktijdig meerdere stromen worden verwerkt die verschillende relatieve relevanties hebben voor de gebruiker van het apparaat. Om dit probleem op te lossen stellen we het nieuwe concept van voorwaardelijk gegarandeerde budgetten voor, en beschrijven we hoe dat concept kan worden gerealiseerd. De technieken voor het analyseren van het planningprobleem voor budgetten zijn gebaseerd op bestaande technieken voor slechtste-gevals-analyse voor periodieke real-time taken. We breiden die bestaande technieken uit met technieken voor beste-gevals-analyse zodat we apparaten die gebruik maken van dit nieuwe type budget kunnen analyseren.

In vivo Glut4 translocation in lean and fatty Zucker rat hearts: effect of insulin dose and time

Glucose transporter type 4 (Glut4) is an isoform of facilitative glucose transporters which plays an important role in whole body glucose homeostasis. Glut4 translocation to the plasma membrane from intracellular compartments is regulated by insulin in insulin-sensitive tissues including the heart. Cardiac insulin resistance in the obese (fa/fa) Zucker rat has been characterized by depressed glucose utilization as well as glucose transport. Glucose transporter translocation has been assessed in the insulin resistant heart by measuring total glucose transporters and was shown to be responsive to insulin under in vitro conditions. The aim of the present study was to examine specifically the translocation of the Glut4 isoform in the heart of obese rats under in vivo conditions. The insulin dose effect and the time course of cardiac Glut4 translocation in vivo was examined in lean (FA/? ) and fatty (fa/fa) Zucker rats by determining the subcellular distribution of Glut4. Plasma membrane and intracellular membrane fractions were purified from the heart ventricles isolated from rats either in the basal state or injected with insulin. Glut4 content in the membrane fractions was determined using a competitive ELISA method. Insulin injection, given at doses 2.5, 5 and 10 LVkg, increased plasma insulin levels in both lean and fatty Zucker rats when compared to the basal level of each phenotype (p<0.05, one-way ANOVA). Insulin resistance in the fatty Zucker rat was shown by the inability of all three doses of insulin to significantly reduce plasma glucose (p>0.05, one-way ANOVA) in spite of the elevation in plasma insulin levels. On the other hand, plasma glucose was significantly reduced with all three insulin doses in lean Zucker rats (p<0.05, one-way ANOVA). At the highest insulin dose and at 20 minutes post insulin injection, Glut4 recruitment to the plasma membrane in lean rats was shown by a significant increase (30%) in plasma

Aerated hydration treatment improves the response of Brassica juncea and Brassica campestris seeds to stress during germination

Seed lots of Brassica juncea and Brassica campestris that differed in quality were subjected to aerated hydration (AH) for up to 24 h at 20°C. In both species, the rate of germination, final germination (% normal seedlings) and germination after the controlled deterioration test increased after AH treatment in seeds that initially had reduced seed quality. The optimum timing of treatment was 12 h in both species. The germination of two seed lots of Brassica juncea was tested before and after 12 h AH at a range of water potentials (0 to -1.00 MPa) and salinities (0-331.8 mmolal NaCI). Both the final normal germination (%) and germination rate, as measured by mean germination time, decreased as water stress (decreased water potential) and salinity increased. However in all cases the normal germination (%) was markedly higher for AH treated seeds. Thus at -0.73 MPa, the normal germination of untreated seed of the two lots was 47 and 55% (mean of two repeat runs) compared with 90 and 91% following AH. Similarly, at 220.3 mmolal NaCI, the normal germination of the two lots increased to 78 and 85% after AH treatment, compared with 43 and 57% for untreated seeds. The effect of AH treatment on germination at a range of temperatures (8-37°C) was examined for seed lots of Brassica campestris. Germination increased at temperatures both above (33-37°C) and below (8-10, 13-14°C) the optimum for germination (22-23°C), thus extending the range of temperatures for successful germination. These results are discussed in relation to establishment under stressful conditions and the role of germination advancement and metabolic repair during AH treatment.
Die regionale Mittelverteilung für die aktive Arbeitsmarktpolitik: Politikberatung des IAB für Zwecke der Maßnahmesteuerung (The regional distribution of budgetary funds for active labour market policy: policy advice by the IAB for the purpose of allocating resources for employment schemes)

"Since the employment promotion reform law came into force at the beginning of 1998, the resources for active labour market policy - e.g. training measures and job creation schemes - have been paid from a common budget, the so-called integration title. For the distribution of budgetary funds amounting to approx. DM 25 billion among the regions of the Federal Republic of Germany a formula was sought which was to be based essentially on a labour market indicator. A proposal for the method of distribution (including the indicator) was developed at the IAB in collaboration with the specialist departments of the Federal Employment Services. The criteria for the development were: efficiency of the use of the resources, the most exact possible consideration of the legal guidelines of the Social Code, transparency of the procedure, openness for necessary policy decisions, scientific correctness in implementation. Here the procedure used in constructing the indicator is explained and the distribution result is set out. It was finally passed by the board of directors and the supervisory board of the Federal Employment Services and contains the necessary policy weightings. The history of the implementation of the instrument for the distribution of resources, which has considerable effects on regional policy and economic policy, is also dealt with briefly.

An Examination of Long‐Lived Asset Impairments

Prior research reveals that write‐offs of long‐lived assets are both large in magnitude and frequent in occurrence. Responding to calls for enhanced reporting of these items, the FASB issued SFAS No. 121, Accounting for the Impairment of Long‐Lived Assets. However, its effect on the characteristics of reported write‐offs remains unclear, as implementation requires inherently subjective estimates. Further, critics (including dissenting FASB board members and the SEC) question the standard's guidance. Motivated in part by this debate, this paper contrasts the characteristics of write‐offs reported prior versus subsequent to the issuance of SFAS No. 121. Empirical results reveal that economic factors have a weaker association with write‐offs reported after SFAS No. 121. This is consistent across macro, industry, and firm‐specific variables. Results also indicate a higher association between write‐offs and “big bath” reporting behavior after the standard's implementation, and that this “big bath” behavior mor.
