Authors: Nemati-Anaraki Leila , Aghajani Koupaei Hamed , Alibeyk Mohammadreza 
Published: July 2017

Background: Today, in addition to citations and with the expansion of social media, the use of altmetrics has gained attention as a tool necessary for evaluating the effects of scientific publications. The present study intended to monitor Iranian pediatrics articles, as one of the leading areas of scientific publications in Iran, between the years 2010-2016 using altmetrics and citation-metrics, and then evaluate the relationship between the altmetric score and number of received citations. Methods: This is a practical study of the analytical descriptive type and the research methodology is scientometrics. This research included 1332 research articles, review articles and conference articles in the field of pediatrics from Iran during 2010-2016, published in the Web of Science. Authors, year, journal and social media was determined in these articles. Data analysis was carried out using SPSS21 software and descriptive and inferential statistics (Kolmogorov-Smirnov test and Spearman correlation). Results: A total of 1138 articles have citations and 256 articles had altmetric activity. The results indicate a significant correlation among the articles’ altmetric scores and number of received citations. Among the data sources of altmetric score, mentions of articles in Mendeley, Twitter, and Facebook had the highest ranking. The number of times an article was read in Mendeley had a significant correlation with the number of citations. Conclusions: It seems that altmetrics better represent the impact of newer articles, while older articles had received more citations. In addition, a high number of reads in Mendeley correlates with received citations. However, Mendeley reads do not involve altmetric score calculation algorithms, and this should be implemented in the future.

Published: July 2017

Background: Sickle cell patients produce more reactive oxygen species (ROS) than healthy individuals, leading to increased cell membrane damage. Theoretically, reducing ROS formation would preserve red cell membranes of sickle cell patients. Vitamin C is a powerful anti-oxidant capable of inhibiting ROS formation in a variety of situations, by functioning as an electron donor to reduce molecular oxygen. This study aimed to determine whether Vitamin C reduced ROS formation in sickle red cells.Methods:27 homozygous (HbSS) patients were recruited from the outpatient clinics of Lagos University Teaching Hospital, Nigeria, and annex at the Sickle Cell Foundation, Lagos, Nigeria. Demographic information and EDTA patient blood samples were collected. The test group were red cells preincubated in 80uM and 100uM Vitamin C concentrations before stressing with tertbutylhydroperoxide. These were compared to stressed matched controls preincubated in phosphate buffered saline. Cell staining was done with CellRox Orange followed by flow cytometry to quantify ROS.Results: ROS count for Vitamin C pre-treated red cells was significantly lower than matched controls (p<0.001). Average ROS count for 80uM test samples was 27.5/ul (95% CI, 17.5 to 72.5) and for 100uM 3.9/ul (95% CI, 1.9 to 5.9). Male gender was significantly associated with elevated baseline ROS count (p=0.03).Conclusion:Vitamin C reduced ROS formation in HbSS cells. Future studies should focus on a role for Vitamin C as a safe, cheap addition to maintenance therapy of sickle cell patients.
An Overview of School Dropout in Central America: Unresolved Issues and New Challenges for Education Progress
Authors: Adelman Melissa A. , Szekely Miguel 
Published: July 2017

<p style="text-align:justify">School dropout is a growing concern in Central America, and in Latin America as a whole, because of its consequences for economic productivity, the inclusiveness of growth, social cohesion, and increasing youth risks. This paper utilizes more than two decades of household survey data to construct a systematic overview of school dropout at the primary and secondary levels in Central America, focusing on recent trends in dropout patterns and their underlying causes. Within each country, poverty, rurality, and indigenous group membership are the strongest correlates of dropout, reflecting several underlying factors that affect the marginal benefits and costs of staying in school. Global and regional evidence increasingly points to common policy priorities for reducing dropout across Central America, including addressing remaining gaps in access at the pre-primary and secondary levels, improving the quality of education at all levels, and strengthening the coverage, targeting, and coherence of existing programs aimed at improving education outcomes. However, additional rigorous evaluations, including cost data, are needed to identify the most effective specific approaches in each country. JEL Classification: I2, I24, I25, I26, I28, O15</p>
Phenomenologies in The Flowing Live Present
Authors: Fraleigh Sondra 
Published: July 2017

Abstract
Phenomenology is a popular qualitative method of enquiry, but not all phenomenology is the same. There are basic differences, and, at the same time, common threads that define an approach as phenomenological. Outgrowths of phenomenology are rooted in Edmund Husserl’s philosophy, now differentiated and widely applied in the arts, social science, psychology, somatic fields of enquiry and religious studies. Husserl’s foundational ideas return throughout this article. In Part 2, I engage connections between phenomenology, spirituality and dance. My hope is that practitioners and scholars of dance who are drawn to phenomenology will find themselves somewhere in this study.
Effects of Some Additives on In Vitro True Digestibility of Wheat and Soybean Straw Pellets
Authors: Kılıc Unal , Gulecyuz Emre 
Published: July 2017

AbstractThis study was aimed to explore the nutrient content, relative feed values (RFV) andin vitrotrue digestibilities (IVTD) of wheat straw and soybean straw pellets produced with the addition of molasses, guar meal and sepiolite. In this experiment, 16 groups were created for 2 different straws (wheat/soybean straws), 2 different sepiolite applications (available/not available) and 4 different applications (control, guar meal, molasses, guar meal+molasses) in accordance with the 2×2×4 factorial design. A Daisy incubator was used to determine the IVTD of the feeds. According to the results, molasses and guar meal increased the RFV of soybean straws, while molasses and guar meal treatments and sepiolite did not affect the RFV of wheat straws. It was observed that sepiolite increased the RFV’s of soybean straw for guar meal and guar meal+molasses. The higher IVTD’s were found for guar meal (without sepiolite) treatment of soybean straw and guar meal (with sepiolite) treatment of wheat straw. Molasses and guar meal addition to wheat and soybean straws improved the crude protein contents. In conclusion, straw pelleting can be used as an alternative forage conservation method to close the gap in forage supply during the winter.
Differential BPFs with Multiple Transmission Zeros Based on Terminated Coupled Lines
Authors: Niu Yiming , Yang Guo , Wu Wen 
Published: July 2017

AbstractDifferential bandpass filters (BPFs) named Filter A and Filter B based on Terminated Coupled Lines (TCLs) are proposed in this letter. The TCLs contributes to not only three poles in differential-mode (DM) for wideband filtering response but also multiple zeros in both DM and common-mode (CM) offering wide DM out-of-band rejection and good CM suppression. Fabricated filters centred at 3.5 GHz with wide DM passband and wideband CM suppression have been designed and measured. The filters improved the noise suppression capability of the communication and radiometer systems. The simulated and measured results are in good agreement.
Numerical Simulation of Heat Distribution with Temperature-Dependent Thermal Conductivity in a Two-Dimensional Liquid Flow

Published: July 2017

Abstract
This paper is a contribution to a better understanding of heat transfer through porous channels used for mechanical sieving and filtration of liquids. The problem modeled by means of the Navier–Stokes equations and the energy equation is similar to a viscous flow between two uniformly permeable walls fixed at different temperatures. Thermal behaviors are determined through three branches denoted solutions of types I, II and III of a diagram of bifurcations presenting the values of the wall shear stress as the Reynolds number varies. We found that the distribution of temperature is similar through branches I and II where a large horizontal inflection area is observed as the Péclet number increases. This large horizontal inflection area inside the channel denotes the presence of thermal boundary layers which more precisely occur across branches I and II when the Péclet number approaches the value of 10. On the other hand, along branch III, thermal boundary layers do not exist and temperature presents a different behavior compared to those of branches I and II.

Published: July 2017

AbstractBackground:Severe hypertriglyceridemia (HTG) as well as diabetic ketoacidosis (DKA) are complications of type 1 diabetes (T1DM). HTG is an exceedingly rare complication in the pediatric population and herein we report a case of HTG at new-onset T1DM in DKA and discuss management and potential complications.Case presentation:An 11-year-old previously well patient with a history of fatigue and weight loss presented with: glucose >600 mg/dL, venous blood gas: pH 7.26, pCOConclusions:Lipemia secondary to severe HTG, though exceedingly rare, may exist in new onset T1DM with DKA. Complicating the diagnosis is the possibility of an analytical error from lipemia causing incongruence in diagnostic criteria. Clinicians should rely on clinical criteria for management and should consider HTG if laboratory data is inconsistent with the clinical picture.

AbstractBackground:Survivors of acute lymphoblastic leukemia (ALL) may experience endocrine dysfunction. This study evaluated growth and pubertal patterns in survivors of childhood ALL.Methods:Longitudinal assessment of anthropometric measurements and pubertal status was performed in a retrospective cohort of survivors (n=183). Median age at last endocrine visit was 16.1 years (range 8.2–27.6); median follow-up time was 8.7 years (range 3–21.4).Results:Treatment with chemotherapy+prophylactic cranial radiation (pCRT, n=29) was associated with lower mean height standard deviation score (SDS) than chemotherapy alone (n=154) (p=0.001) and higher prevalence of adult short stature (13% vs. 2.2%). Mean age at pubertal onset was normal (girls: 10.3±1.3 years; boys: 12.0±1.3 years). Precocious puberty, diagnosed in 8.7% of patients, was more prevalent in pCRT-treated girls. Rates of overweight and obesity were 22.9% and 9.3%, respectively. Predictors of endocrine disorders were pCRT (p=0.031) and female gender (p=0.041); of obesity, higher body mass index (BMI)-SDS at diagnosis (p=0.001); and of short stature, lower height-SDS at diagnosis (p=0.038).Conclusions:Most childhood ALL survivors given chemotherapy alone attain normal adult height and puberty. Childhood ALL survivors are at increased risk of overweight, especially those with increased BMI at diagnosis. Clinicians should screen for overweight early in survivorship and introduce early interventions.

Published: July 2017

AbstractObjective:Echocardiography is the most important tool to assess infants with congenital diaphragmatic hernia (CDH) for pulmonary hypertension (PH). The pattern of blood flow in the pulmonary artery [described as time to peak velocity (TPV)/right ventricular ejection time (RVET) ratio] provides distinct information about pulmonary arterial pressure. The aim of our study was to investigate the correlation of TPV/RVET measurements with the most commonly used classification system for PH in CDH newborns and the association of these measurements with outcome parameters.Methods:Echocardiographic measurements were obtained in 40 CDH newborns within 6 h of life. The obtained measurements were correlated with the decision for or against extracorporeal membrane oxygenation (ECMO); early mortality; total duration of mechanical ventilation and total duration of oxygen supplementation.Results:The correlation coefficient between severity of PH and TPV/RVET measurements was −0.696 (P<0.001). Using receiver operating characteristic (ROC) analyses the optimal cutoff for TPV/RVET in order to predict the necessity for ECMO or early mortality without ECMO was 0.29 with a sensitivity of 86.7%, a specificity of 68%, a positive predictive value of 61.9% and a negative predictive value of 89.5%. Newborns with a TPV/RVET below the cutoff had a 5.9-fold risk for ECMO or early mortality, a significantly longer duration of mechanical ventilation (13.4 days vs. 7.4 days, P=0.003) and oxygen supplementation (22.4 days vs. 9.0 days, P=0.019), and a lower survival rate (76.2% vs. 100%, P=0.021).Conclusions:TPV/RVET is a feasible parameter to assess PH in CDH newborns with close correlation to outcome parameters.
Impact factors on fetal descent rates in the active phase of labor: a retrospective cohort study
Authors: Kimmich Nina , Juhasova Jana , Haslinger Christian , Ochsenbein-Kölble Nicole , Zimmermann Roland 
Published: July 2017

Abstract

Aim:
To assess fetal descent rates of nulliparous and multiparous women in the active phase of labor and to evaluate significant impact factors.

Methods:
In a retrospective cohort study at the University Hospital of Zurich, Switzerland, we evaluated 6045 spontaneous vaginal deliveries with a singleton in vertex presentation between January 2007 and July 2014 at 34 0/7 to 42 0/7 gestational weeks. Median fetal descent rates and their 10th and 90th percentiles were assessed in the active phase of labor and different impact factors were evaluated.

Results:
Fetal descent rates are exponentially increasing. Nulliparous women have slower fetal descent than multiparous women (P<0.001), ranging from 0 to 5.81 cm/h and from 0 to 15 cm/h, respectively. The total duration of fetal descent in labor is 5.42 h for nulliparous and 2.71 h for multiparous women. Accelerating impact factors are a lower fetal station, multiparity, increasing maternal weight and fetal occipitoanterior position, whereas epidural anesthesia decelerates fetal descent (P<0.001).

Conclusions:
Fetal descent is a hyperbolic increasing process with faster descent in multiparous women compared to nulliparous women, is highly inter individual and is associated with different impact factors. The diagnosis of labor arrest or prolonged labor should therefore be based on such rates as well as on individual evaluation of every parturient.
Muscle stem cell and physical activity: what point is the debate at?

Published: July 2017

Abstract
In the last 15 years, it emerged that the practice of regular physical activity reduces the risks of many diseases (cardiovascular diseases, diabetes, etc.) and it is fundamental in weight control and energy consuming to contrast obesity. Different groups proposed many molecular mechanisms as responsible for the positive effects of physical activity in healthy life. However, many points remain to be clarified. In this mini-review we reported the latest observations on the effects of physical exercise on healthy skeletal and cardiac muscle focusing on muscle stem cells. The last ones represent the fundamental elements for muscle regeneration post injury, but also for healthy muscle homeostasis.
Interestingly, in both muscle tissues the morphological consequence of physical activity is a physiological hypertrophy that depends on different phenomena both in differentiated cells and stem cells. The signaling pathways for physical exercise effects present common elements in skeletal and cardiac muscle, like activation of specific transcription factors, proliferative pathways, and cytokines. More recently, post translational (miRNAs) or epigenetic (DNA methylation) modifications have been demonstrated. However, several points remain unresolved thus requiring new research on the effect of exercise on muscle stem cells.

Published: July 2017

Abstract
Determination of toxic lead ions at trace level using solid-based adsorbents has become of interest in recent years. In this work, a novel bio-adsorbent originating from papaya peel waste (PPw) and magnetic nanoparticles (Fe3O4) was developed (Fe3O4/PPw). The new adsorbent was prepared using a one-pot green method and characterized by Fourier transform infrared, X-ray diffractometer, energy-dispersive X-ray spectroscopy and field emission scanning electron microscopy. The synthesized Fe3O4/PPw was used as a magnetic solid-phase extraction (MSPE) sorbent for extraction of lead ions from waste water prior to assessing by flame atomic absorption spectroscopy. The parameters influencing extraction recovery, including desorption solvent, solvent volume, sample volume, extraction time, desorption time, adsorbent dosage, salt effect and pH were optimized. A linear response for the MSPE method was achieved at concentrations from 10 to 100 ng mL−1 with a good coefficient of determination (R
2=0.9987). Detection limits and quantitation limit of the MSPE method were observed around 2 ng mL−1 and 6.6 ng mL−1, respectively. The intraday and interday precision (%RSD) was in the range 1.6%–4.5% and 2.3%–7.4%, respectively. The recovery amounts obtained were 91% for tap water, 85.9% for river water and 86% for waste water. The synthesized adsorbent showed a minimum reusability of eight cycles without significant change in the lead determination. The results proved that the new bio-adsorbent (Fe3O4/PPw) is potentially capable to extract the Pb(II) from aqueous media under optimum conditions with a high extraction efficiency.
Generating prediction bands for path forecasts from SETAR models
Authors: Grabowski Daniel , Staszewska-Bystrova Anna , Winker Peter 
Published: July 2017

AbstractPrediction bands for time series are usually generated point-wise by bootstrap methods. Such bands only convey the prediction uncertainty for each horizon separately. The joint distribution is not taken into account. To represent the forecast uncertainty over the entire horizon, methods for constructing joint prediction bands for path forecasts from SETAR models are proposed. This class of nonlinear models is increasingly used in time series analysis and forecasting as it is useful for capturing nonlinear dynamics. Approaches based on statistical theory and explicit sequential and global optimization methods are both considered. Monte Carlo simulation is used to assess the performance of the proposed methods. The comparison is done with regard to the actual coverage of the constructed prediction bands for full path forecasts as well as with regard to the width of the bands. An empirical application demonstrates the relevance of the choice of bands for indicating the uncertainty of path forecasts in nonlinear models.

Abstract
McGuinness, A, Malone, S, Petrakos, G, and Collins, K. The physical and physiological demands of elite international female field hockey players during competitive match play. J Strength Cond Res 33(11): 3105–3113, 2019—The aim of the current investigation was to quantify the physical and physiological demands of elite international female field hockey match play across halves of play. Thirty-eight participants (24 ± 5 years; 173 ± 5 cm; 72 ± 5 kg) took part in 19 competitive matches during the 2014–2015 season. Participants were monitored with global positioning system technology and heart rate monitors. Players were categorized based on 3 different playing positions. Activity was categorized into total (m), high-speed running distance (m; >16 km·h−1), and relative distance (RD) (m·min−1) due to the use of rolling substitutions. Heart rate was classified based on the percentage of players' individual peak heart rate (HRpeak) determined by a Yo-Yo intermittent recovery level 1 test. Players spent on average 44 ± 7 minutes in match play. The total distance (TD) covered was 5,558 ± 527 m (125 ± 23 m·min−1) with 589 ± 160 m (13 ± 4 m·min−1) completed at high speed. Defenders covered a greater TD compared with other positions of play (p ≤ 0.001). Midfield players covered a greater distance at high speed (p ≤ 0.001) with the forwards having a higher relative distance (p ≤ 0.001). The HRpeak of the players was 199 ± 1 b·min−1 with a mean exercise intensity of 86 ± 7.8% of HRpeak. The time spent >85% HRpeak decreased significantly across the halves (p = 0.04, η2 = 0.09, small). Defenders were found to spend more time >85% HRpeak when compared with forwards (p ≤ 0.001). The current investigation provides normative data that coaches should consider when constructing training regimen.

Published: July 2017

AbstractIn eukaryotic cells, RNA polymerase I (Pol I) synthesizes precursor ribosomal RNA (pre‐rRNA) that is subsequently processed into mature rRNA. To initiate transcription, Pol I requires the assembly of a multi‐subunit pre‐initiation complex (PIC) at the ribosomal RNA promoter. In yeast, the minimal PIC includes Pol I, the transcription factor Rrn3, and Core Factor (CF) composed of subunits Rrn6, Rrn7, and Rrn11. Here, we present the cryo‐EM structure of the 18‐subunit yeast Pol I PIC bound to a transcription scaffold. The cryo‐EM map reveals an unexpected arrangement of the DNA and CF subunits relative to Pol I. The upstream DNA is positioned differently than in any previous structures of the Pol II PIC. Furthermore, the TFIIB‐related subunit Rrn7 also occupies a different location compared to the Pol II PIC although it uses similar interfaces as TFIIB to contact DNA. Our results show that although general features of eukaryotic transcription initiation are conserved, Pol I and Pol II use them differently in their respective transcription initiation complexes.
