Temporal Evolution of The Intensity of Inflammatory Bowel Disease in Children: Correlation Of a Semi-Quantitative Analysis of Bowel Uptake in White Blood Cells Scintigraphy with Biological Parameters

Background: White Blood Cells Scintigraphy(WBCS)has shown to be an accurate method for the diagnosis of Inflammatory Bowel Disease(IBD). Clinical and biological parameters are used to evaluate the intensity of IBD during the follow-up, but are relatively inaccurate. In the order to evaluate the role of WBCS in the follow up of children with IBD, we retrospectively studied the correlation between the evolution of the WBCS results using a semi-quantitative index, the Scan Activity Index(SAI),and results of different biological parameters measured at two different times during the follow-up. Methods: Thirty-four WBCS were performed in 17 children(mean age:13.5 years)with IBD(14 Crohn'sDisease,3 ulcerative colitis). The mean interval time between 2 sequential WBCS was 14 months(range:5-27 months). WBCS were performed at 30 min and 2-3h after injection of(superscript 99m)Tc-HMPAO labeled leukocytes. The SAI was measured by comparing the intensity of uptake in 8 bowel segments with the physiologic uptake present in the bone marrow, liver and spleen. SAI corresponds to the sum of the intensity of uptake for all segments. The evolution of the SAI was correlated with those of erythrocyte sedimentation rate(ESR),WBC(WBC)and platelets(PLAT)counts Results: The SAI value was decreased, unchanged and increased in 11,3 and 3 patients, respectively. The ESR was decreased, unchanged and increased respectively in 9,4 and 4 patients. The counts of WBC and PLAT were unchanged in 7 and 11 patients, respectively. A correlation was observed between the evolution of SAI and ESR in 11 patients. Discordant data were observed for 2 patients with an improvement of SAI and worsening of ESR and the opposite for 1 patient. No significant correlation was found between SAI and WBC or PLAT. Conclusion: The stability of WBC and platelets values observed in most of the patients emphasizes the limitation for the use of these parameters to assess the evolution of the intensity of IBD.WBCS using SAI, in association with ESR, seems to be a useful tool to evaluate the temporal evolution of intensity of IBD.
Suspected natural lysosomal storage disease from ingestion of pink morning glory (Ipomoea carnea) in goats in northern Argentina

This study describes an occurrence of pink morning glory (Ipomoea carnea) intoxication in goats in northern Argentina. The clinical signs displayed by the affected animals were ataxia, lethargy, emaciation, hypertonia of the neck muscles, spastic paresis in the hind legs, abnormal postural reactions and death. The clinico-pathologic examination revealed that the affected animals were anemic and their serum level of aspartate aminotransferase was significantly increased. Cytoplasmic vacuolation in the Purkinje cells and pancreatic acinar cells was observed by histological examination. The neuronal lectin binding pattern showed a strong positive reaction to WGA (Triticum vulgaris), sWGA (succinylated T. vulgaris) and LCA (Lens culinaris). Although I. carnea is common in tropical regions, this is the first report of spontaneous poisoning in goats in Argentina.
Electronic Excitation Transfer in the LH2 Complex of Rhodobacter sphaeroides

Ultrafast fluorescence upconversion measurements were carried out on the peripheral (LH2) light harvesting antenna complex of Rhodobacter sphaeroides isolated in the detergents N-octyl-β-d-glucopyranoside and lauryl dimethylamine oxide. The B800 and B850 bands were excited in separate experiments, and the B850 emission was detected in each case. We make use of the recently determined crystal structure of a purple bacterial LH2 complex to simulate our data and to calculate the exciton level structure of the B850 aggregate. The B800 to B850 excitation transfer occurs with a 650 fs time constant. The depolarization of B850 emission follows a wavelength dependent, biexponential decay with time constants 50−90 and 400−500 fs. We can reproduce the non-exponentiality of the depolarization by assuming incoherent hopping between dimeric sites with a 250 cm-1 full width at half-maximum (fwhm) Gaussian distribution of site energies (inhomogeneity). We calculate the homogeneous hopping time between dimers in B850 to .
Contrasting convective regimes over the Amazon: Implications for cloud electrification

[1] Four distinct meteorological regimes in the Amazon basin have been examined to distinguish the contributions from boundary layer aerosol and convective available potential energy (CAPE) to continental cloud structure and electrification. The lack of distinction in the electrical parameters (peak flash rate, lightning yield per unit rainfall) between aerosol-rich October and aerosol-poor November in the premonsoon regime casts doubt on a primary role for the aerosol in enhancing cloud electrification. Evidence for a substantial role for the aerosol in suppressing warm rain coalescence is identified in the most highly polluted period in early October. The electrical activity in this stage is qualitatively peculiar. During the easterly and westerly wind regimes of the wet season, the lightning yield per unit of rainfall is positively correlated with the aerosol concentration, but the electrical parameters are also correlated with CAPE, with a similar degree of scatter. Here cause and effect are difficult to establish with available observations. This ambiguity extends to the “green ocean” westerly regime, a distinctly maritime regime over a major continent with minimum aerosol concentration, minimum CAPE, and little if any lightning.
Repossession and the Democratization of Credit

We exploit a 2004 credit reform in Brazil that simplified the sale of repossessed cars used as collateral for auto loans. We show that the reform expanded credit to riskier, self-employed borrowers who purchased newer, more expensive cars. The legal change has led to larger loans with lower spreads and longer maturities. Although the credit reform improved riskier borrowers' access to credit, it also led to increased incidences of delinquency and default. Our results shed light on the consequences of a credit reform and highlight the crucial role that collateral and repossession play in the liberalization and democratization of credit.
System modeling based on machine learning for anomaly detection and predictive maintenance in industrial plants

Electricity, water or air are some Industrial energy carriers which are struggling under the prices of primary energy carriers. The European Union for example used more 20.000. 000 GWh electricity in 2011 based on the IEA Report [1]. Cyber Physical Production Systems (CPPS) are able to reduce this amount, but they also help to increase the efficiency of machines above expectations which results in a more cost efficient production. Especially in the field of improving industrial plants, one of the challenges is the implementation of anomaly detection systems. For example as wear-level detection, which improves maintenance cycles and thus leads to a better energy usage. This paper presents an approach that uses timed hybrid automata of the machines normal behavior for a predictive maintenance of industrial plants. This hybrid model reduces discrete and continuous signals (e.g. energy data) to individual states, which refer to either the present condition of the machines. This allows an effective anomaly detection by implementing a combined data acquisition and anomaly detection approach, and the outlook for other applications, such as a predictive maintenance planning. Finally, this methodology is verified by three different industrial applications.
Student Veteran Success: A Grounded Theory Study

Student veterans in undergraduate post-secondary education face many challenges. Current research addresses these unique challenges and offers recommendations for further research, as well as strategies for college administrators and faculty seeking to assist student veterans. However, the research does not address the strategies student veterans use to succeed. The purpose of this grounded theory study is to start this conversation. The objective of this study is to present a theory that predicts and explains student veterans’ success, using grounded theory methodology to examine student veteran strategies to succeed in college. Thirteen student veterans from two different colleges participated in the study via semi-structured interviews and theoretical sampling. The data from the interviews and sampling sessions were coded using in-vivo and axial coding techniques until theoretical categories emerged. Study results showed that student veterans succeeded because they were adaptable and empathetic, and could prioritize their efforts based on goal setting, both on and off campus. Successful student veterans put more effort into their life outside of college, and tended to be internally motivated to succeed. Academic excellence and college degrees were secondary motivators, and fell behind broader-based life goals. The theory developed in this study offers guidance for future research on student veteran success. It also provides valuable insight that will allow post-secondary faculty, administration, and staff who work with student veterans in post-secondary education, to replicate this study’s strategies for success. Lastly, it shows that, to student veterans and their supporters, life after the military is about more than college.

The Effectiveness of Embolotherapy for Treatment of Hemoptysis in Patients with Varying Severity of Tuberculosis by Assessment of Chest Radiography

The effectiveness of percutaneous embolotherapy in cases of hemoptysis due to pulmonary tuberculosis from increasing severity of lung parenchymal injury was compared. The pattern of pleural involvement, as seen on chest radiography and angiography, were comparatively analyzed in 230 patients who were available for follow-ups from March 1992 to December 2003. Chest radiography findings were classified into 4 types based on levels of complicated lesions and pleural involvement. Angiography findings were divided into 4 groups based on the level of blood supply to lesions. Early hemostasis with respect to radiographic group were as follows: Type I- 92% (73/79), Type II- 80% (52/65), Type III- 70% (42/60), and Type IV- 56% (52/92); there was an average success rate of 73% (219/296), and continued hemostasis was found in 80% of Type I patients (62/77), 77% of Type II patients (41/53), 62% of Type III patients (25/40), and 45% of Type IV patients (27/60), with an average long-term hemostatic rate of 67% (155/230). Increasing severity of pleural involvement and associated complications correlated with increasing development of systemic collateral arteries other than the bronchial artery. The severely increased circulation in systemic collateral arteries makes it difficult to predict good hemostatic results following embolization. Therefore, we recommend aggressive treatment, such as surgical intervention, after embolization in such instances.
Effects of Resistance Training and Soy Isoflavone on Body Composition in Postmenopausal Women

Objective. To investigate the independent and additive effects of resistance training (RT) and soy isoflavone (ISO) on body composition in postmenopausal women (PW). Method. This study used a placebo-controlled, double-blind (soy), randomized (ISO versus placebo) × (RT versus No RT) design. A total of 80 PW, aged 45–70 years, were randomly (71 completed 9-months intervention): RT + ISO (n = 15), No RT + ISO (n = 20), RT + placebo (n = 18), and No RT + placebo (n = 18). ISO received 100 mg a day of isoflavone; and to RT attended supervised resistance training sessions. At baseline and 9-months, fat and muscle mass were estimated by DXA. ANOVA and test t were used. Results. RT groups showed significantly increased muscle strength (35.2%) and muscle mass (1.4%). Exercising attenuated gains in fat trunk and % body fat (P < .05). Significant decreases in muscle mass (−1.8%) and increases in fat mass of the whole-body (1.6%) and trunk (9.7%) was found in no-RT groups (P < .05). In ISO groups, there were no differences in body composition and muscle strength. ISO and RT had no additive effects. Conclusion. In PW: RT improved muscle mass and strength and attenuated gain of fat mass; ISO did not alter body composition and muscle strength; there were no additive effects of RT and ISO.
Different Transcriptional Responses from Slow and Fast Growth Rate Strains of Listeria monocytogenes Adapted to Low Temperature

Listeria monocytogenes has become one of the principal foodborne pathogens worldwide. The capacity of this bacterium to grow at low temperatures has opened an interesting field of study in terms of the identification and classification of new strains of L. monocytogenes with different growth capacities at low temperatures. We determined the growth rate at 8°C of 110 strains of L. monocytogenes isolated from different food matrices. We identified a group of slow and fast strains according to their growth rate at 8°C and performed a global transcriptomic assay in strains previously adapted to low temperature. We then identified shared and specific transcriptional mechanisms, metabolic and cellular processes of both groups; bacterial motility was the principal process capable of differentiating the adaptation capacity of L. monocytogenes strains with different ranges of tolerance to low temperatures. Strains belonging to the fast group were less motile, which may allow these strains to achieve a greater rate of proliferation at low temperature.
Hubungan Antara Self-Efficacy dengan Kecemasan Komunikasi dalam Mempresentasikan Tugas di Depan Kelas

Psychology student is required to have a good communication skills in situations of personal and public. One of the competencies that must be owned by bachelor of psychology are skilled in interpersonal communication and have an ability to communicate with each other. Handling the anxiety experienced by individuals may differ between one individual with another individual depends on an individual assessment of the capabilities that called self-efficacy (Sarafino, 1994). Self-efficacy is a believefrom individual against all aspects of the advantages who aims to reach an achievement. A total of 175 students in Udayana University and Dhyana Pura University are still actively follow lectures and do an individual presentations in front of the class became a subject in this correlational quantitative study. The sampling technique used was simple random sampling Data were processed using Pearson Product Moment analysis, simple linear regression, independent sample t-test, and one-way ANOVA analysis. Statistical analysis show, there is significant correlation between self-efficacy and communication apprehensionin order to do presentation in front of class (r = -0,725; p = 0,000). The coefficient of determination obtained for 0,540 which means that 54 % of the variance that occurs in the communication apprehension in order to do a presentationin front of the class variable can be explained by the variance in self-efficacy variable. T test and F test analysis found that the mean scores for communication apprehension in order to do a presentationin front of the class did not differ significantly when assessed from the gender (T = 1,389; p = 0,167) and there are differences in communication apprehension in presenting the task in front of the class when examined from many individual presentation experience (F = 15,848 ; p = 0,000). Keywords: Self-efficacy, communication apprehensionwhen presenting the task in front of the class, students of Psychology.
Surgical mask vs N95 respirator for preventing influenza among health care workers: a randomized trial.

CONTEXT Data about the effectiveness of the surgical mask compared with the N95 respirator for protecting health care workers against influenza are sparse. Given the likelihood that N95 respirators will be in short supply during a pandemic and not available in many countries, knowing the effectiveness of the surgical mask is of public health importance. OBJECTIVE To compare the surgical mask with the N95 respirator in protecting health care workers against influenza. DESIGN, SETTING, AND PARTICIPANTS Noninferiority randomized controlled trial of 446 nurses in emergency departments, medical units, and pediatric units in 8 tertiary care Ontario hospitals. INTERVENTION Assignment to either a fit-tested N95 respirator or a surgical mask when providing care to patients with febrile respiratory illness during the 2008-2009 influenza season. MAIN OUTCOME MEASURES The primary outcome was laboratory-confirmed influenza measured by polymerase chain reaction or a 4-fold rise in hemagglutinin titers. Effectiveness of the surgical mask was assessed as noninferiority of the surgical mask compared with the N95 respirator. The criterion for noninferiority was met if the lower limit of the 95% confidence interval (CI) for the reduction in incidence (N95 respirator minus surgical group) was greater than -9%. RESULTS Between September 23, 2008, and December 8, 2008, 478 nurses were assessed for eligibility and 446 nurses were enrolled and randomly assigned the intervention; 225 were allocated to receive surgical masks and 221 to N95 respirators. Influenza infection occurred in 50 nurses (23.6%) in the surgical mask group and in 48 (22.9%) in the N95 respirator group (absolute risk difference, -0.73%; 95% CI, -8.8% to 7.3%; P = .86), the lower confidence limit being inside the noninferiority limit of -9%. CONCLUSION Among nurses in Ontario tertiary care hospitals, use of a surgical mask compared with an N95 respirator resulted in noninferior rates of laboratory-confirmed influenza.

Antigen Gene Transfer to Human Plasmacytoid Dendritic Cells Using Recombinant Adenovirus and Vaccinia Virus Vectors

Recombinant adenoviruses (RAd) and recombinant vaccinia viruses (RVV) expressing tumour-associated antigens (TAA) are used as anti-tumour vaccines. It is important that these vaccines deliver the TAA to dendritic cells (DC) for the induction of a strong immune response. Infection of myeloid DC (MDC) with RAd alone is relatively inefficient but CD40 retargeting significantly increases transduction efficiency and DC maturation. Infection with RVV is efficient without DC maturation. Plasmacytoid dendritic cells (PDC) play a role in the innate immune response to viral infections through the secretion of IFNα but may also play a role in specific T-cell induction. The aim of our study was to investigate whether PDC are better targets for RAd and RVV based vaccines. RAd alone hardly infected PDC (2%) while CD40 retargeting did not improve transduction efficiency, but it did increase PDC maturation (25% CD83 positive cells). Accordingly, specific CTL activation by RAd infected PDC was limited (the number of IFNγ producing CTL was reduced by 75% compared to stimulation with peptide loaded PDC). RVV infected PDC specifically stimulated CTL but PDC were not activated. These Results indicate that PDC are not ideal targets for RAd and RVV based vaccines. However, PDC induced specific CTL activation after pulsing with recombinant protein, indicating that PDC can also cross-present antigens released from surrounding infected cells.
Self-similarity and fractional Brownian motions on Lie groups

The goal of this paper is to define and study a notion of fractional Brownian motion on a Lie group. We define it as at the solution of a stochastic differential equation driven by a linear fractional Brownian motion. We show that this process has stationary increments and satisfies a local self-similar property. Furthermore the Lie groups for which this self-similar property is global are characterized. Finally, we prove an integration by parts formula on the path group space and deduce the existence of a density.
Supporting Information A: Modified Kinetic Model by Douma Et Al

Douma et al. [1] based several kinetic parameters for the model equations (section 2.1) on work by van Gulik et al. [2]. More recently, De Jonge et al. re-evaluated the kinetic parameters, with improved methods for determining the residual í µí° ¶ í µí± [3], yielding í µí± í µí± ,í µí±í µí±í µí±¥ and í µí°¾ í µí± as reported in table S.1. For consistency, this means í µí°¾ í µí± in eq. 2 must be refitted, yielding í µí°¾ í µí± = 8.36 ⋅ 10 −6 mols/kg The updated model parameters are shown in table S.1. In eq. 2, í µí± í µí± is proportional to the availability of limiting enzyme; the first term represents enzyme synthesis, the second represents decay and dilution. In the Herbert-Pirt equation (eq. 3) í µí¼ is negative if í µí± í µí± < í µí± í µí± í µí± í µí± í µí± ⁄ + í µí± í µí± which can be interpreted as consumption of stored carbon, or cell death due to starvation; fundamentally, a negative í µí¼ is not problematic. However, í µí¼ < 0 is a problem in eq. 2. Synthesis becomes negative for í µí¼ < 0, which is not deemed realistic and can lead to a negative í µí± í µí± giving numerical instabilities. In the second term of eq. 2, í µí¼ < 0 gives rise to an unrealistic enzyme increase. We propose two simple modifications to prevent this behaviour. The first term is set to 0 for í µí¼ < 0 to prevent negative synthesis. In the second term, í µí¼ is replaced by |í µí¼| such that í µí¼ < 0 leads to enzyme destruction rather than concentration. We stress there is no experimental backing for these choices, but we deem them defendable for the goal of our investigation. The modified version of eq. 2 is eq. S.1: í µí±í µí± í µí± í µí±í µí±¡ = í µí»½⋅max(0,í µí¼) 1 + (í µí° ¶ í µí± í µí°¾ í µí±) í µí± − (í µí°¾ í µí±í µí°¸+ |í µí¼|)í µí± í µí± (S.1) Table S.1: Parameters of the black box kinetic model applied in this study [1-3].
