Motivation and Intention to Integrate Physical Activity Into Daily School Life

Research on the motivation of stakeholders to integrate physical activity into daily school life is limited. The purpose was to examine the motivation of stakeholders to participate in a world record physical activity event and whether motivation was associated with future intention to use activity breaks during the daily school life and future participation in a similar event. After the 2012 JAM (Just-a-Minute) World Record event, 686 adults (591 women; 76.1% participated for children <10 years) completed measures of motivational regulations and future intention to (a) use the activity breaks and (b) participate in the event. High intrinsic motivation and low extrinsic motivation and amotivation for participation in the next event were reported. Hierarchical regression analysis, controlling for age, gender, and occupation, showed that intrinsic forms of motivation positively predicted, whereas amotivation negatively predicted, future intention to participate in the event and use the activity breaks. Multivariate analyses of variance revealed that school-related participants were more intrinsically motivated and intended to use the activity breaks and repeat the event more than those who were not affiliated with a school. Nonschool participants reported higher extrinsic motivation and amotivation than school-related participants.
Option Market Liquidity: Commonality and Other Characteristics

This study examines option market liquidity using Ivy DB's OptionMetrics data. We establish convincing evidence of commonality for various liquidity measures based on the bid-ask spread, volumes, and price impact. The commonality remains strong even after controlling for the underlying stock market's liquidity and other liquidity determinants such as volatility. Smaller firms and firms with a higher volatility exhibit stronger commonalities in option liquidity. Aside from commonality, we also uncover several other important properties of the option market's liquidity. First, information asymmetry plays a much more dominant role than inventory risk as a fundamental driving force of liquidity. Second, the market-wide option liquidity is closely linked to the underlying stock market's movements. Specifically, the options liquidity responds asymmetrically to upward and downward market movements, with calls reacting more in up markets and puts reacting more in down markets.
A Preliminary Detection of Physical and Chemical Properties, Inhibitory Substances and Preservatives in Raw Milk

The achieved results in analysis of this study proved that the most common types of adulteration were addition of water, partial skimming or both types together especially in case of samples collected from dairy shops and street vendors, while the samples collected from dairy farms may safely concl ude with Egyptian legal standards. On the other hand, dairy farms milk samples were negative for preservatives except traces of formalin and hydrogen peroxide which may contaminate the milk during sterilization process. While, in case of examined milk samples collected from dairy shops and street vendors, most of preservatives were present especially nitrate. Furthermore, all examined milk samples were free from salicylic acid.
Review of an institutional experience of coronary arterial fistulas in childhood set in context of review of the literature

Coronary artery fistulas are uncommon in children. We conducted a retrospective review of the case notes of 17 children who presented to our institution with the diagnosis of a coronary fistula since 1970. Their median age was 2.3 years. In five patients, there were associated congenital cardiac anomalies, with four having these as part of the spectrum of tetralogy of Fallot. Surgical correction was performed in nine patients, while in five closure was achieved using percutaneous embolization with coils. No complications or deaths were encountered related to the treatments chosen. In two patients, further procedures were needed to close residual fistulas. The median follow-up was 16 years, and on echocardiography, all fistulas appeared to be successfully closed, albeit that we lost three patients to follow up. We also conducted a review of 426 cases of coronary fistulas reported in children in the English literature. We have compared these findings with our institutional experience.
Role of receptor internalization in the agonist‐induced desensitization of cannabinoid type 1 receptors

Agonist‐induced internalization of G protein‐coupled receptors (GPCRs) is an important mechanism for regulating signaling transduction of functional receptors at the plasma membrane. We demonstrate here that both caveolae/lipid‐rafts‐ and clathrin‐coated‐pits‐mediated pathways were involved in agonist‐induced endocytosis of the cannabinoid type 1 receptor (CB1R) in stably transfected human embryonic kidney (HEK) 293 cells and that the internalized receptors were predominantly sorted into recycling pathway for reactivation. The treatment of CB1 receptors with the low endocytotic agonist Δ9‐THC induced a faster receptor desensitization and slower resensitization than the high endocytotic agonist WIN 55,212‐2. In addition, the blockade of receptor endocytosis or recycling pathway markedly enhanced agonist‐induced CB1 receptor desensitization. Furthermore, co‐expression of phospholipase D2, an enhancer of receptor endocytosis, reduced CB1 receptor desensitization, whereas co‐expression of a phospholipase D2 negative mutant significantly increased the desensitization after WIN 55,212‐2 treatment. These findings provide evidences for the importance of receptor endocytosis in counteracting CB1 receptor desensitization by facilitating receptor reactivation. Moreover, in primary cultured neurons, the low endocytotic agonist Δ9‐THC or anandamide exhibited a greater desensitization of endogenous CB1 receptors than the high endocytotic agonist WIN 55,212‐2, CP 55940 or 2‐arachidonoyl glycerol, indicating that cannabinoids with high endocytotic efficacy might cause reduced development of cannabinoid tolerance to some kind cannabinoid‐mediated effects.
Influence of Otitis Media on Hearing and Development

Otitis media affects nearly every child at some time; many children have mild-to-moderate hearing losses for prolonged periods. The effects of these losses on language and educational development may be significant; possible mechanisms are discussed. Especially in suboptimal listening situations, speech perception may be impaired by even a mild hearing loss. Patterns of imperception are predicted by comparison of composite audiometric data from children with middle ear effusions with speech power data, and by analysis of sound pressure waveforms of speech filtered to simulate the typical hearing loss of these patients. A new method of analysis of brain stem evoked responses, yielding response components attributable to binaural interaction, is reported. This and other evoked response techniques may be able to identify objective changes in auditory nervous system function attributable to relative sensory deprivation during development. Finally, directions for further research in this area are discussed.
Ras‐driven proliferation and apoptosis signaling during rat liver carcinogenesis is under genetic control

Fast growth and deregulation of G1 and S phases characterize preneoplastic and neoplastic liver lesions of genetically susceptible F344 rats, whereas a G1‐S block in lesions of resistant BN rats explains their low progression capacity. However, signal transduction pathways responsible for the different propensity of lesions from the 2 rat strains to evolve to malignancy remain unknown. Here, we comparatively investigated the role of Ras/Erk pathway inhibitors, involved in growth restraint and cell death, in the acquisition of a phenotype resistant or susceptible to hepatocarcinogenesis. Moderate activation of Ras, Raf‐1 and Mek proteins was paralleled in both rat models by strong induction of Dab2 and Rkip inhibitors. Levels of Dusp1, a specific ERK inhibitor, increased only in BN rat lesions, leading to modest ERK activation, whereas a progressive Dusp1 decline occurred in corresponding lesions from F344 rats and was accompanied by elevated ERK activation. Furthermore, a gradual increase of Rassf1A/Nore1A/Mst1‐driven apoptosis was detected in both rat strains, with highest levels in BN hepatocellular carcinoma (HCC), whereas loss of Dab2IP, a protein implicated in ASK1‐dependent cell death, occurred only in F344 rat HCC, resulting in significantly higher apoptosis in BN than F344 HCC. Taken together, our results indicate a control of the Ras/Erk pathway and the pro‐apoptotic Rassf1A/Nore1A and Dab2IP/Ask1 pathways by HCC susceptibility genes. Dusp1 possesses a prominent role in the acquisition of the phenotype resistant to HCC by BN rats, whereas late activation of RassF1A/Nore1A and Dab2IP/Ask1 axes is implicated in the highest apoptosis characteristic of BN HCC. © 2008 Wiley‐Liss, Inc.
Immunohistochemical Localization of Hepatocyte Growth Factor Activator (HGFA) in Developing Mouse Liver Tissues: Heterogeneous Distribution of HGFA Protein

Hepatocyte growth factor activator (HGFA) can activate the single-chain hepatocyte growth factor (HGF) required for embryonic development. We studied the immunohistochemical (IHC) localization of HGFA in adult mouse liver and its developmental changes from embryonic day 12 to postnatal day 30. A heterogeneous distribution of HGFA was observed in adult liver tissues. The hepatocytes around the hepatic veins were preferentially positive for HGFA, whereas those in other areas were negative. Depending on the vascular diameter, the hepatic veins were bordered by a one- to three-cell-thick layer of hepatocytes positive for HGFA, which showed evidence of cell–cell heterogeneity in staining intensity. Immunoelectron microscopy detected ubiquitous distribution of the gold particle reaction product for HGFA in the cytoplasm of these hepatocytes, especially in the rough endoplasmic reticulum. Developmental analysis indicated that there was hardly any staining of HGFA until postnatal day 0 and that noticeable staining was initially detected in the pericentral hepatocytes on postnatal day 3. Subsequently, immunoreactivity increased and the distinct staining pattern had been established by postnatal day 30. These results suggest that HGFA proteins are produced in the hepatocytes surrounding the efferent hepatic veins in the mouse and that development of the unique distributing pattern takes place postnatally.
Community-Based, Culturally Sensitive HIV/AIDS Education for Aboriginal Adolescents: Implications for Nursing Practice

Research is an essential component of effective, evidence-based nursing practice. Limited scientific data have been published on Canadian Aboriginals, and even less information is available on HIV prevention efforts aimed at Aboriginal youth. The need for more research on HIV and AIDS among Aboriginals, and especially Aboriginal youth, is highlighted throughout the article as a means to improving prevention interventions for this vulnerable population. At the same time, insights gained from a culture-sensitive, HIV/AIDS educational program that targeted a group of Aboriginal adolescents from a local First Nations community in Ontario are discussed. Implications for future HIV/AIDS peer-based prevention efforts using the train-the-trainer technique are also considered.
Potential use of the fungus Beauveria bassiana against the western flower thrips Frankliniella occidentalis without reducing the effectiveness of its natural predator Orius sauteri (Hemiptera: Anthocoridae)

Abstract Orius sauteri (Poppius; Hemiptera: Anthocoridae) is an important predator of western flower thrips, Frankliniella occidentalis (Pergande; Thysanoptera: Thripidae). O. sauteri would be directly exposed to the entomopathogenic fungus Beauveria bassiana (Bals.) Vuillemin in the field should the fungus be used as a biopesticide. If the fungus were to negatively affect O. sauteri in agro-ecosystems, predation of F. occidentalis by O. sauteri may be limited. The present study was undertaken to evaluate the insecticidal activity of strain B.bassiana-RSB of B. bassiana, which is highly virulent to F. occidentalis, on the predator under laboratory conditions. Results showed that, regardless of the concentration applied to first instars, Bb-RSB was not insecticidal against O. sauteri, nor did direct applications affect the developmental rate of the predator. Significant differences in developmental rates and adult longevity were observed between O. sauteri that fed on Bb-RSB-infected F. occidentalis cadavers and those that fed on untreated thrips. Developmental time (from first instar to adult) increased from 0.3 to 0.7 days and adult longevity decreased by 0.8 to 1.2 days for predators fed thrips treated with low and high concentrations of strain Bb-RSB, respectively, compared with predators fed on untreated thrips. However, these differences were only 3–13% of mean values for the controls, suggesting that the effects of Bb-RSB on O. sauteri are relatively minor. These findings highlight the potential use of O. sauteri in combination with B. bassiana for the biocontrol of F. occidentalis, but field tests must be performed to confirm their compatible use.
Identifying Novel Type ZBGs and Nonhydroxamate HDAC Inhibitors Through a SVM Based Virtual Screening Approach

Histone deacetylase inhibitors (HDACi) have been successfully used for the treatment of cancers and other diseases. Search for novel type ZBGs and development of non‐hydroxamate HDACi has become a focus in current research. To complement this, it is desirable to explore a virtual screening (VS) tool capable of identifying different types of potential inhibitors from large compound libraries with high yields and low false‐hit rates similar to HTS. This work explored the use of support vector machines (SVM) combined with our newly developed putative non‐inhibitor generation method as such a tool. SVM trained by 702 pre‐2008 hydroxamate HDACi and 64334 putative non‐HDACi showed good yields and low false‐hit rates in cross‐validation test and independent test using 220 diverse types of HDACi reported since 2008. The SVM hit rates in scanning 13.56 M PubChem and 168K MDDR compounds are comparable to HTS rates. Further structural analysis of SVM virtual hits suggests its potential for identification of non‐hydroxamate HDACi. From this analysis, a series of novel ZBG and cap groups were proposed for HDACi design.
Duchenne Muscular Dystrophy: Functional Ischemia Reproduces Its Characteristic Lesions

The highly characteristic early and midstage histological lesions of Duchenne dystrophy were reproduced experimentally in the rat by the combination of a vascular abnormality, aortic ligation, which does not affect the structure of the intramuscular blood vessels, and the humoral vasoactive substance 5-hydroxytryptamine. Neither ligation nor injection of 5-hydroxytryptamine alone causes changes in the muscle fibers. This result establishes the possibility of a similar combined mechanism for a nonstructural ischemia pathogenesis in Duchenne dystrophy. The proposed pathogenesis is contrary to the generally held idea that the cause is an intrinsic abnormality of muscle fiber metabolism.
Molecular Genetic Analysis of SLC3A1 and SLC7A9 Genes in Czech and Slovak Cystinuric Patients

Cystinuria is a frequently inherited metabolic disorder in the Czech population (frequency 1/5,600) caused by a defect in the renal transport of cystine and dibasic amino acids (arginine, lysine and ornithine). The disease is characterized by increased urinary excretion of the amino acids and often leads to recurrent nephrolithiasis. Cystinuria is classified into two subtypes (type I and type non‐I). Type I is caused predominantly by mutations in the SLC3A1 gene (2p16.3), encoding heavy subunit (rBAT) of the heterodimeric transporter. Cystinuria non‐I type is caused by mutations in the SLC7A9 gene (19q13.1). In this study, we present results of molecular genetic analysis of the SLC3A1 and the SLC7A9 genes in 24 unrelated cystinuria families. Individual exons of the SLC3A1 and SLC7A9 genes were analyzed by direct sequencing. We found ten different mutations in the SLC3A1 gene including six novel ones: three missense mutations (G140R), D179Y and R365P), one splice site mutation (1137‐2A>G), one deletion (1515_1516delAA), and one nonsense mutation (Q119X). The most frequent mutation, M467T; was detected in 36% of all type I classified alleles. In the SLC7A9 gene we found six mutations including three new ones: one missense mutation (G319R), one insertion (611_612insA) and one deletion (205_206delTG). One patient was compound heterozygote for one SLC3A1 and one SLC7A9 mutation. Our results confirm that cystinuria is a heterogeneous disorder at the molecular level, and contribute to the understanding of the distribution and frequency of mutations causing cystinuria in the Caucasian population.
Inadequate Efficacy of a New Formulation of Fosmidomycin-Clindamycin Combination in Mozambican Children Less than Three Years Old with Uncomplicated Plasmodium falciparum Malaria

ABSTRACT The combination of fosmidomycin and clindamycin (F/C) is effective in adults and older children for the treatment of malaria and could be an important alternative to existing artemisinin-based combinations (ACTs) if proven to work in younger children. We conducted an open-label clinical trial to assess the efficacy, safety, and tolerability of F/C for the treatment of uncomplicated P. falciparum malaria in Mozambican children <3 years of age. Aqueous solutions of the drugs were given for 3 days, and the children were followed up for 28 days. The primary outcome was the PCR-corrected adequate clinical and parasitological response at day 28. Secondary outcomes included day 7 and 28 uncorrected cure rates and fever (FCT) and parasite (PCT) clearance times. Fifty-two children were recruited, but only 37 patients were evaluable for the primary outcome. Day 7 cure rates were high (94.6%; 35/37), but the day 28 PCR-corrected cure rate was 45.9% (17/37). The FCT was short (median, 12 h), but the PCT was longer (median, 72 h) than in previous studies. Tolerability was good, and most common adverse events were related to the recurrence of malaria. The poor efficacy observed for the F/C combination may be a consequence of the new formulations used, differential bioavailability in younger children, naturally occurring variations in parasite sensitivity to the drugs, or an insufficient enhancement of their effects by naturally acquired immunity in young children. Additional studies should be conducted to respond to the many uncertainties arising from this trial, which should not discourage further evaluation of this promising combination.
Knowledge on Acne Vulgaris and Menstrual Cycle: A Study on Adolescent Girls

Acne vulgaris is a common, chronic inflammatory diseases of skin, several factors has been suggested to influence acne including diet, menstruation, sweating, UV radiation, stress, occupation. A cross sectional study was carried out among 164 respondents aged 10-19 years. The aim of this study was to find out the relationship between acne vulgaris and menstrual cycle among adolescents in selected school of Dhaka city. Data were collected through face to face interview of the respondents by using a semi-structured questionnaire. This present study revealed that mean age of the students was 14.3, mean age onset of menstruation (menarche) was 11.9 years ranging from 10 to 15 years. Bi-vitiate analysis revealed that the proportion of acne vulgaris was found to be high among the students aged 15 years and above, 53(51.5%) among 103(62.8%) acne students and without acne 61(37.2%) out of total 164 respondents and the association was statistically significant p value =0.034 . The present study reflects that there is significant difference in treatment with acne which was found statistically high during postmenstrual phase p =0.010 (p<.010) than premenstrual phase p value =0.053 (p<.05).
A new hope for idiopathic pulmonary fibrosis.

I suspect that many of my patients have picked up on more than a hint of frustration in my voice when I tell them that the cause of their shortness of breath is idiopathic pulmonary fibrosis. This frustration stems from the fact that beyond providing information about prognosis or referral for lung transplantation or palliation, there has been little to offer in the way of treatment. Idiopathic pulmonary fibrosis is a chronic, progressive disorder of lung scarring that predominantly affects older patients and has a death rate worse than that of many cancers (3-year survival, 50%). 1 However, in contrast to .
The impact of social conditions on patient adherence to pulmonary tuberculosis treatment.

SETTING Tuberculosis (TB) remains one of the main concerns in global health. One of the main threats to treatment success is patient non-adherence to anti-tuberculosis treatment. OBJECTIVE To identify the relation between social conditions and treatment adherence in a prospective cohort setting in an intermediate TB burden country. DESIGN To identify associations between poor adherence and social conditions, including educational level, type of residence and occupation, we constructed hierarchical logistic regression models. RESULTS A total of 551 participants were included in the study. Low educational levels, poor housing and occupations in the construction and manufacturing industries and service sectors were associated with poor adherence; this association was likely to be differentiated by previous history of anti-tuberculosis treatment. CONCLUSION Policy making should focus on improving the social conditions of patients by working towards better housing conditions and providing health promoting working conditions to enable treatment adherence.
Evaluation of temporal artery thermometry in children 3-36 months old.

PURPOSE This study aims to determine whether temporal artery (TA) thermometer readings are accurate and better tolerated than rectal readings in young children. DESIGN AND METHODS Paired rectal and TA temperature readings and Face Legs Activity Cry and Consolability (FLACC) scores were obtained. RESULTS TA thermometry failed to detect rectal fever (38 degrees C or greater) in approximately 20% of paired temperature readings. FLACC scores were significantly lower after TA readings than after rectal readings. PRACTICE IMPLICATIONS This study questions TA readings as an accurate substitute for rectal thermometry.
Signal-noise ratio and the critical band in fishes.

Auditory thresholds in the presence of masking noise and masking tones were measured in three species of teleost fishes: goldfish (Carassius auratus, family Cyprinidae); pin fish (Lagodon rhomboides, family Sparidae); African mouth‐Breeder (Tilapia macrocephala, family Cichlidae). In the goldfish, the signal‐to‐noise ratio to broad‐band noise was about 22 dB, and direct measurement of the critical band yielded a value between 100 and 200 Hz. Single‐tone masking effects in the goldfish showed partial remote masking, and strong masking at frequencies within 5 to 20 Hz of the signal. The audiograms for pinfish and Tilapia were significantly higher than in the goldfish, but the signal‐to‐noise ratio values were in the same range. Provisionally, the evidence supports the existence of a critical band in the goldfish, but not in the other species tested. The question of the relationship of signal‐to‐noise ratio to the critical band was discussed in reference to the frequency‐discrimination capacities and hearing.
