Absence of mutation of the p73 gene in astrocytic neoplasms.

In subgroups of astrocytic neoplasms, including glioblastoma (GBM), mutations of the p53 tumour suppressor gene lead to loss of growth-suppressive properties. A p53-related gene termed p73 has recently been identified; its gene product shows structural and functional similarities to p53. After being mapped to chromosome region 1p36, p73 was proposed to act as a tumour suppressor gene, as this region is frequently deleted in a variety of human cancers, including astrocytic tumours. To determine whether p73 is involved in astrocytoma/GBM development, we analysed 10 pilocytic astrocytomas, 15 WHO grade II astrocytomas, 15 WHO grade III anaplastic astrocytomas, and 20 GBM for p73 gene alterations. In parallel, we used six polymorphic markers to determine the allelic status of region 1p36 in this tumour series. Although loss of heterozygosity was evidenced in 12 of 60 cases (20% of samples), PCR-SSCP and direct sequencing failed to detect any gene mutation in the entire coding region and intronic sequences of p73. Eight tumours displayed five distinct polymorphic nucleotide changes, also present in the corresponding normal DNA. These variations consisted of T-->C variation, with no change in Thr173; C-->T transition, with no change in His197; exon 9 simultaneous double change C-->T and T-->C , with no variations in Ala336 and His349, respectively, and C-->T change at exon 9/-24 position of intron 8. These results suggest that, in astrocytic gliomas, p73 may not play a major role as a tumour suppressor, but the relatively high incidence of LOH confirms the presence at 1p36 of an as yet unidentified gene of this category, with a key function in astrocytoma/GBM progression.
Circulating MicroRNA Is a Biomarker of Pediatric Crohn Disease

Objective: The gold standard for the diagnosis and evaluation of Crohn disease (CD) is endoscopy/colonoscopy, although this is invasive, costly, and associated with risks to the patient. Recently, circulating microRNAs (miRNAs) have emerged as promising noninvasive biomarkers. Here, we examined the utility of serum miRNAs as biomarkers of CD in children. Patients and Methods: Studies were conducted using sera samples from patients with pediatric CD, healthy controls, and a comparison group of patients with pediatric celiac disease. Serum miRNA levels were explored initially using a microfluidic quantitative reverse transcription-polymerase chain reaction array platform. Findings were subsequently validated using quantitative reverse transcription-polymerase chain reaction in larger validation sample sets. The diagnostic utility of CD-associated serum miRNA was examined using receiver operating characteristic analysis. Results: A survey of miRNA levels in the sera of control and patients with CD detected significant elevation of 24 miRNAs, 11 of which were chosen for further validation. All of the candidate biomarker miRNAs were confirmed in an independent CD sample set (n = 46). To explore the specificity of the CD-associated miRNAs, they were measured in the sera of patients with celiac disease (n = 12); none were changed compared with healthy controls. Receiver operating characteristic analyses revealed that serum miRNAs have promising diagnostic utility, with sensitivities for CD above 80%. Significant decreases in serum miRNAs were observed in 24 incident patients with pediatric CD after 6 months of treatment. Conclusions: The present study identifies 11 CD-associated serum miRNA with encouraging diagnostic potential. Our findings suggest serum miRNAs may prove useful as noninvasive biomarkers in CD.
Urinary tract infection in term neonates with prolonged jaundice.

INTRODUCTION The aim of this study was to evaluate the frequency of urinary tract infection (UTI) in neonates with prolonged jaundice. MATERIALS AND METHODS Newborn infants with jaundice lasted more than 2 weeks were included in this study. Patients who had other signs or symptoms were excluded. Workup of prolonged hyperbilirubinemia was performed, including direct Coomb's test, blood group of the neonate and the mother, complete blood count, blood smear, glucose-6-phosphate dehydrogenase (G6PD), reticulocyte count, serum level of bilirubin (unconjugated and conjugated), thyroid function tests (serum thyroxine [T4] and thyroid-stimulating hormone), urinalysis, and suprapubic urine culture. Pediatric nephrologists carried out further investigation including kidney function tests, renal ultrasonography, voiding cystourethrography, and Technetium Tc 99m dimercaptosuccinic acid renal scintigraphy for patients with a positive urine culture for microorganisms. RESULTS Of 100 neonates who were evaluated, 43 were boys and 57 were girls. All of the neonates were breastfed. Six suffered from UTI (4 boys and 2 girls). Reflux was detected on voiding cystourethrography in 1 and cortical defect in the kidney on renal scan in 2 boys. CONCLUSION In our region, with a high rate of breastfeeding, UTI remains as an important cause of prolonged jaundice. Despite the high rate of urogenital system abnormality accompanied by neonatal UTI, there was not a significant difference between the signs and symptoms of jaundice in patients with and without UTI. Performing urine cultures should be considered as a routine procedure in the evaluation of every infant with prolonged jaundice.
TNF-alpha, PDGF, and TGF-beta(1) expression by primary mouse bronchiolar-alveolar epithelial and mesenchymal cells: tnf-alpha induces TGF-beta(1).

The bronchiolar-alveolar epithelium (BAE) is a primary target site for inhaled agents that cause lung injury. These cells, consequently, release a broad range of mediators that influence other cell populations, including interstitial lung fibroblasts that are central to the development of interstitial pulmonary fibrosis (IPF). A number of peptide growth factors (GF) have been postulated to be essential in the pathogenesis of IPF. We demonstrate here that primary populations of mouse BAE and mesenchymal cells, maintained in culture, synthesize four potent GF. These are platelet-derived growth factor isoforms (PDGF) A and B, transforming growth factor beta-1 (TGF-beta(1)), and tumor necrosis factor alpha (TNF-alpha). A mouse lung epithelial cell isolation technique pioneered in this laboratory has been used to purify the BAE cells to greater than 85% (80 +/- 5.6% alveolar type II and 9 +/- 2.3% Clara cells) in culture. Northern analysis, RNase protection assay, and immunocytochemistry (ICC) were used to establish mRNA and protein expression of the GF over time in the cultured BAE and mesenchymal cells. We show for the first time in these primary mouse lung cells that treatment of both cell types with TNF-alpha upregulates expression of TGF-beta(1). The four GF are produced by both epithelial and mesenchymal cells but with different temporal patterns. TGF-beta(1) is expressed constitutively by BAE and mesenchymal cells, whereas TNF-alpha expression wanes over time. The findings by ICC were consistent with levels of mRNA expression in both cell types. As genetically defined and altered mouse strains are becoming increasingly valuable for modeling lung disease, studying the gene expression patterns of target cells from these animals in vitro would be useful in sorting out the complex responses by individual cell types of the lung and the interactions among the multitude of mediators that are released during lung cell injury.
Pension Fund Restoration Policy in General Equilibrium : Tinbergen Institute MPhil Thesis

This paper quantifies the business cycle effects and distributional implications of pension fund restoration policy after the economy has been hit by a financial shock. We extend a canonical New-Keynesian dynamic general equilibrium model with a tractable demographic structure and a pension fund. Numerical simulations show that economies with pension funds that primarily write off accumulated pension wealth to restore financial adequacy behave similarly to an economy without a pension fund. Significant deviations from laissez-faire arise when the pension fund increases the pension fund contribution rate to close the funding gap or postpones the closure of the funding gap. At a cost of significantly distorting aggregate labour supply and output, the pension fund can shelter the group of retirees from unanticipated shocks by guaranteeing the value of their accumulated pension wealth. A defined benefit pension fund can be welfare improving to the group of agents that is already born in the period the financial shock hits. However, since pension funding gaps are typically closed over an extended period of time, a part of the welfare gains to currently alive agents comes at the expense of future, currently unborn, generations.
Work Ethics in Bugis; Connecting Culture and Entrepreneurial Behavior

This paper aimed at investigating the Bugis Value System and Work Ethics and their effect on Entrepreneurial Behavior among Bugis Entrepreneurs. In addition, this paper also focused on the connection between culture and the emergence of entrepreneurial behavior. Work Ethics emerges from cultural values within a country which favor a country to face day-to-day challenge. One’s ethnicity is hardly separated from his/her culture and values. Social life is the reflection of culture and its values whereas they emerge from various sources such as from daily interaction within society or from ancient manuscripts. Bugis Value System can be tracked from many sources like Lontara manuscripts, folk tales, folk songs, and from other modern publications. In terms of entrepreneurial behaviors, the Bugis Value System contains certain values and teachings in which the people of Bugis might have taken as the source of their attitude and behavior. This system later contributes to their entrepreneurial behavior and influences their success in running business. Keywords—Work Ethic, Bugis Value System, and Entrepreneurial Behavior.
Feeding Mode of Australian Infants in the First 12 Months of Life

Background: In 2011, Australia published a set of 6 population-level indicators assessing breastfeeding, formula use, and the introduction of soft/semisolid/solid foods. Objectives: This study aimed to report the feeding practices of Australian infants against these indicators and determine the predictors of early breastfeeding cessation and introduction of solids. Methods: Mother–infant dyads (N = 1470) were recruited postnatally in 2 Australian capital cities and regional areas of 1 state between February 2008 and March 2009. Demographic and feeding intention data were collected by self-completed questionnaire at infant birth, with feeding practices (current feeding mode, age of breastfeeding cessation, age of formula and/or solids introduction) reported when the infant was between 4 and 7 months of age, and around 13 months of age. Multiple logistic regression was used to determine the predictors of breastfeeding cessation and solids introduction. Results: Although initiation of breastfeeding was almost universal (93.3%), less than half of the infants were breastfed to 6 months (41.7%) and 33.3% were receiving solids by 4 months. Women who were socially disadvantaged, younger, less educated, unpartnered, primiparous, and/or overweight were most likely to have ceased breastfeeding before 6 months of age, and younger and/or less educated women were most likely to have introduced solid food by 4 months of age. Not producing adequate milk was the most common reason provided for cessation of breastfeeding. Conclusion: The feeding behaviors of Australian infants in the first 12 months fall well short of recommendations. Women need anticipatory guidance as to the indicators of breastfeeding success and the tendency of women to doubt the adequacy of their breast milk supply warrants further investigation.
Mutations of the cystic fibrosis gene, but not cationic trypsinogen gene, are associated with recurrent or chronic idiopathic pancreatitis

OBJECTIVE:We investigated whether mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) gene and cationic trypsinogen gene are associated with recurrent acute, or chronic idiopathic pancreatitis.METHODS:Twenty patients with idiopathic pancreatitis (11 women, nine men; mean age, 30 yr) were studied for the presence of a CFTR mutation by screening the genomic DNA for more than 30 mutations and variants in the CFTR gene. Selected mutations of the cationic trypsinogen gene were screened by Afl III restriction digestion or by a mutation-specific polymerase chain reaction (PCR). In each patient exons 1, 2, and 3 of the cationic trypsinogen gene were sequenced. Patients with a CFTR mutation underwent evaluation of further functional electrophysiological test (intestinal current measurement). RESULTS:No mutation of the cationic trypsinogen gene was detected. A CFTR mutation was detected in 6/20 (30.0%) patients. Three patients (15.0%) had a cystic fibrosis (CF) mutation on one chromosome (ΔF508, I336K, Y1092X), which is known to cause phenotypical severe cystic fibrosis. One patient was heterozygous for the 5T allele. In addition, two possibly predisposing CFTR variants (R75Q, 1716G→A) were detected on four patients, one of these being a compound heterozygous for the missense mutation I336K and R75Q. No other family member (maternal I336K; paternal R75Q; sister I1336K) developed pancreatitis. An intestinal current measurement in rectum samples of patients with a CFTR mutation revealed no CF-typical constellations.CONCLUSIONS:CFTR mutations are associated with recurrent acute, or chronic idiopathic pancreatitis, whereas mutations of the cationic trypsinogen mutation do not appear to be a frequent pathogenetic factor.
Indoor air pollution from solid fuel and tuberculosis: a systematic review and meta-analysis.

OBJECTIVE To conduct an updated systematic review and meta-analysis on the association between indoor air pollution and tuberculosis (TB). DESIGN We searched for English or Chinese articles using PubMed and EMBASE up to 28 February 2013. We aimed to identify randomised controlled trials and observational epidemiological studies that reported the association between domestic use of solid fuel and TB. Two reviewers independently extracted the information from included studies and assessed the risk of bias of these studies using pre-defined criteria. The effect sizes of eligible studies were pooled using a random-effects model; the heterogeneity across studies was quantified using I(2) statistics. RESULTS We identified 15 studies on solid fuel use and active TB and one on solid fuel use and latent tuberculous infection. The summary odds ratios from case-control and cross-sectional studies were respectively 1.17 (95%CI 0.83 - 1.65) and 1.62 (95%CI 0.89 - 2.93), with substantial between-study heterogeneity (I(2) 56.2% and 80.5%, respectively). Subgroup analysis and meta-regression analysis did not identify any study-level factors that could explain the heterogeneity observed. CONCLUSION The level of evidence for the association between domestic use of solid fuels and TB was very low. High-quality studies are badly needed to clarify this association and to estimate the magnitude of the problem.
Brain abscesses: clinical experience and outcome of 52 consecutive cases.

BACKGROUND Brain abscesses are still a very important pathology, with high mortality and morbidity, even with the advancement of imaging technologies and antibiotic treatment. In this study, we analyzed the relationship between clinical, biological and therapeutic features at admission and clinical outcome in patients with brain abscesses. MATERIAL AND METHOD This is a retrospective study over 52 consecutive patients with brain abscesses treated in our Neurosurgical Department during 8 years, between January 2003 and December 2011. Laboratory tests, cerebral CT or MRI scans, blood and urine cultures were performed. Surgical treatment consisted of either CT guided stereotactic aspiration or craniotomy with the resection of the abscess. Materials from the brain abscess were cultured for aerobic and anaerobic bacteria. Parenteral antibiotic therapy usually lasted between 6 to 8 weeks. RESULTS Clinical outcome was assessed at 6 months endpoint by using Glasgow Outcome Scale (GOS). The most common cause of brain abscess was hematogenous spread. There were 41 patients with solitary and 11 with multiple brain abscesses. Regarding microbiological findings, we obtained positive cultures from brain materials in 41 patients. Stereotactic aspiration was performed in 33 patients, surgical excision in 15 and medical therapy alone in 4 patients. As clinical outcome, 84.6% patients had a favorable outcome (GOS 5 and 4) and 15.4% had an unfavorable outcome (severe disability - 4 and death - 4). CONCLUSIONS Early diagnosis, optimal surgical intervention and timely use of appropriate antibiotics are essential for a good outcome. No significant difference in outcome was found among various surgical treatment modalities. For mortality, initial Glasgow Coma Score (GCS) 8, associated predisposing factors and systemic infections were significant contributing factors.
Morphological Changes in Blood Vessels Produced by Hyperosmotic Agents and Measured by Optical Coherence Tomography¶

Abstract Optical tissue clearing by hyperosmotic chemical agents significantly increases light depth penetration in skin and may improve light-based therapeutics such as laser treatment of cutaneous vascular lesions. A feasibility study was conducted to evaluate the potential role of optical clearing by glycerol in laser treatment of cutaneous vessels. Optical imaging was performed to investigate the morphological effects of glycerol on blood vessels of skin. Blood vessels were imaged using Doppler optical coherence tomography in in vivo hamster skin treated with glycerol. Images were obtained from the subdermal side to assess morphological changes in the blood vessels caused by glycerol and from the epidermal side to assess enhanced Doppler imaging of blood vessels. Application of glycerol to the subdermis resulted in venule stasis and for prolonged treatment times, arteriole stasis. In cases where flow remained in arterioles, an improved Doppler signal was detected from blood vessels when imaging transepidermally compared with the native condition. Intensity images indicated changes in blood optical properties and improved contrast of skin cross sections after glycerol application. The observed optical and morphological effects were reversed upon hydration of the skin with phosphate-buffered saline. The combination of increased depth of light penetration and the temporary slowing or cessation of flow in blood vessels could mean improved laser treatment of vessels.
Voxel selection framework with signal decomposition for fMRI based brain activity classification

This paper presents an fMRI signal analysis methodology using Empirical mean curve decomposition (EMCD) and mutual information (MI) based voxel selection framework. Previously, the fMRI signal analysis has been carried out either using empirical mean curve decomposition (EMCD) model or voxel selection on raw fMRI signal. The first methodology does signal decomposition that makes voxel selection process easy while the latter methodology does selection of relevant voxels (or features). Both these advantages are added by our methodology in which the frequency component is considered by decomposing the raw fMRI signal using Empirical mean and the voxels are selected from EMCD signal. The proposed methodologies are adopted for predicting the neural response. Experimentations are carried out in the openly available fMRI data of six subjects and comparisons are made with existing decomposition model and voxel selection framework. The comparative results demonstrate the superiority of the proposed methodology.
Steady-state Pharmacokinetics of Nevirapine Extended-release Tablets in HIV-1–infected Children and Adolescents: An Open-label, Multiple-dose, Cross-over Study

Background: To compare steady-state (ss) pharmacokinetic targets of nevirapine extended-release (NVP-XR) tablets once-daily (QD) with immediate-release (NVP-IR) tablet or oral suspension twice-daily in HIV-1–infected children and adolescents. Methods: Phase I, open-label, multidose, cross-over study with optional extension phase, in 85 patients 3 to <18 years of age, previously on an NVP-IR–based regimen for ≥18 weeks with baseline viral load <50 copies/mL. Patients were stratified by age, treated with NVP-IR twice-daily for 11 days, then NVP-XR QD for 10 days. Cpre,ss (steady-state, predose concentrations) was obtained from all, and 12-hour NVP-IR and 24-hour NVP-XR steady-state pharmacokinetic profiles were obtained in the pharmacokinetic substudy. Viral loads, CD4 counts and adverse events (AEs) were monitored. Results: Eighty patients completed the trial. Adjusted geometric mean (gMean) Cpre,ss for NVP-XR and NVP-IR exceeded the target of 3000 ng/mL, and the adjusted gMean NVP-XR:NVP-IR ratio (90% confidence interval) for QD normalized and un-normalized Cpre,ss were 91.2% (83.5–99.6%) and 91.8% (83.7–100.7%). gMean 24-hour area under the curve at steady-state NVP-XR:NVP-IR for un-normalized dose was 90.4% and un-normalized Cpre,ss NVP-XR:NVP-IR were 91.0%, 81.9% and 103.7% for the 3 age groups, 3 to <6, 6 to <12 and 12 to <18 years, respectively. gMean values indicated no exposure to subtherapeutic NVP concentrations and viral suppression was adequate and maintained in all QD groups. Most AEs were mild and similar between age groups. No serious or Division of AIDS Grade 4 AEs or AE related treatment discontinuations occurred. Conclusions: NVP-XR exhibited adequate trough concentrations with equivalent area under the curve at steady-state relative to NVP-IR. NVP-XR was well-tolerated and is a valuable treatment option for HIV-infected children and adolescents.
The impact of intellectual capital on innovation via the mediating role of knowledge management: a structural equation modelling approach

This study aims to investigate the impact of intellectual capital on innovation in telecommunication companies in Jordan, through the presence of knowledge management as a mediator. Data were collected using a self-administrated questionnaire from 498 employees working in three telecommunication companies in Jordan. Structural equation modelling approach based on AMOS 22.0 was used to examine the causal relationships and to test the hypotheses between the observed and latent constructs in the proposed research model. The results led to the confirmation of a mediation model as intellectual capital did not have a direct impact on innovation. The results revealed that intellectual capital did have a significant impact on knowledge management and the latter on innovation. In light of these findings, implications to both theory and practice are discussed.
