Authors: Ahumada-Padilla Ericka , Villarroel del Pino Luis , Bustamante-Ara Natalia
Published: February 2020

Introducción: Una buena condición física (CF) se relaciona, entre muchos beneficios, a modificaciones funcionales y estructurales cerebrales que favorecen el aprendizaje. Objetivo: Analizar la asociación entre CF y rendimiento académico (RA) en escolares chilenos según sexo y determinar si la dependencia administrativa de la escuela influye en dicha asociación.Sujetos y Método: Estudio transversal sobre datos poblacionales de escolares de 8° básico evaluados por SIMCE-2011. La muestra incluyó solo escolares de 13 y 14 años, de ambos sexos, con todas las pruebas de CF y RA rendidas. Los resultados de CF y RA fueron categorizados en malo, regular y bueno. Se realizó una regresión logística binaria explicando un buen RA a partir de las categorías de CF según sexo y dependencia administrativa, ajustando por edad, estado nutricional, nivel educacional de los padres y nivel socioeconómico de la escuela.Resultados: De 19.929 registros se consideraron 12.338 escolares donde 47,9% fueron mujeres. Presentaron buena CF 33,4% de las mujeres y 49,5% de los hombres, y buenRA 16,9% y 21,5%, respectivamente. Escolares con buena CF presentaron más chances de alcanzar buen RA que escolares con mala CF (mujeres: 84% y hombres 78% más; p < 0,001). Considerando la dependencia administrativa, buena CF en mujeres de colegios municipales aumentó las posibilidades en 334% (p < 0,001) y en hombres de colegios particulares subvencionados, en 91% (p = 0,01).Conclusión: Tanto mujeres como hombres con buena CF tienen más posibilidades de alcanzar un buen RA. Al incluir la dependencia administrativa la asociación persiste en mujeres de colegios municipales y en hombres de colegios particulares subvencionados.

Published: February 2020

La nefropatía falciforme (NF) es una complicación poco estudiada en la edad pediátrica, que se manifiesta en diferentes formas, incluyendo la glomerulopatía y la tubulopatía.Objetivo: Describir las complicaciones renales agudas y crónicas de niños con anemia de células falciformes (ACF).Pacientes y Método: Estudio de cohorte restrospectiva. Se incluyeron pacientes pediátricos con diagnóstico confirmado de enfermedad de células falciformes que tuvieran estudio nefro-urológico. Se consignó patrón electroforético de hemoglobina, presencia y tipo de afectación renal, y presencia de compromiso cardiológico. Se realizó análisis bivariado para comparar pacientes con y sin NF.Resultados: Se incluyeron 79 pacientes, 59.5% hombres, siendo el patrón electroforético más frecuente Hb-SS (60.9%). La NF se presentó en el 70% de ellos, con una edad de 114 meses (RIQ 65-157). Las alteraciones más frecuentemente encontradas fueron hiperfiltración glomerular, microalbuminuria, lesión renal aguda, hipertensión arterial e hipostenuria. En el análisis bivariado, un ecocardiograma anormal fue más frecuente en los pacientes con NF (84,8% vs 54,3% p = 0,01), así como tuvieron una tendencia a mayor uso de medicamentos nefrotóxicos (74,5% vs 54,2% p = 0,07).Conclusiones: Nuestros hallazgos sugieren que la nefropatía falciforme puede presentarse a temprana edad, siendo muy frecuente la hiperfiltración glomerular. Las complicaciones cardiopulmonares en ACF se podrían asociar con la presencia NF.

Published: February 2020

El tumor de Bednar es un sarcoma de bajo grado, infrecuente, considerado como la variante pigmentada del dermatofibrosarcoma protuberans (DFSP).Objetivo: describir las características clínicas, histopatológicas, el tratamiento y la evolución de un caso pediátrico de esta infrecuente neoplasia.Caso Clínico: escolar de 9 años que consultó por una pápula indurada asintomática, de dos años de evolución en el dorso del cuarto dedo del pie izquierdo. La biopsia incisional de la lesión fue compatibles con un DFSP pigmentado. El estudio inmunohistoquímico mostró positividad intensa para CD34 en toda la lesión, con factor XIIIa negativo. Se complementó el estudio de la pieza histológica con citogenética molecular FISH para el gen PDGFB (22q13.1) el cual reflejó un patrón anómalo en las células tumorales, no así en los melanocitos ni en la piel peritumoral. Se realizó cirugía micrográfica de Mohs diferida con cobertura mediante sustituto dérmico, sin recidiva ni recurrencia tumoral a los 5 años de seguimiento.Conclusiones: El DFSP pigmentado es un sarcoma de bajo grado, que muy infrecuentemente se presenta en pacientes pediátricos. Las variantes clásica y pigmentada deben ser sospechadas ante una lesión papulonodular única, de crecimiento lento y progresivo, con presencia de células fusiformes con patrón estoriforme en la biopsia y con estudio inmunohistoquímico positivo para CD34. Es una entidad con buen pronóstico, con escaso riesgo de recurrencia y metástasis, si se logra la realización de una extirpación completa

Published: February 2020

La onicomicosis (OM) es una infección fúngica de las uñas, cuyo principal agente causal es el Tricophytum rubrum. Si bien es una patología infrecuente en niños, se ha observado un aumento en la prevalencia en el último tiempo. Hasta la fecha, existen diversos estudios y guías clínicas de OM en adultos. Sin embargo, la literatura en edad pediátrica es escasa, lo que dificulta el tratamiento en pediatría. En el presente articulo se revisa la literatura actual, los métodos diagnosticos de OM, datos epidemiológicos locales y globales, y se presentan las opciones de tratamiento disponibles considerando su eficacia y perfil de seguridad en población pediátrica.

El ensayo de dihidrorodamina (DHR) es utilizado para el diagnóstico y detección de portadoras, además proporciona información sobre patrones de herencia.Objetivo: Detectar casos de EGC en niños con infecciones recurrentes y evaluar a sus familiares femeninas mediante el ensayo de DHR, para identificar portadoras y obtener información acerca de posibles patrones de herencia.Pacientes y Método: Fueron incluidos 107 pacientes (<18 años de edad) con sospecha clínica de EGC como neumonías, linfadenopatías y abscesos, remitidos por médicos de hospitales públicos, del 2014 al 2017. Además, se incluyeron seis mujeres, familiares de los niños con EGC. A las muestras de los pacientes se aplicó el ensayo DHR, expresando los resultados como índice de estimulación de neutrófilos (IE).Resultados: La mediana de edad de los pacientes fue de 3 años y 62/107 fueron varones. El IE promedio fue 39.7±13.8 y 101/107 niños exhibieron un cambio completo de fluorescencia de DHR. En 2/107 niños no se observó dicho cambio (IE=1.0), lo cual indica posible EGC-LX, y un tercer niño mostró un leve cambio (IE=4.8), compatible con EGC-AR. En 5/6 mujeres se encontró un patrón bimodal, indicando un estado de portadora.Conclusiones: Fueron detectados tres casos de EGC y cinco portadoras mediante el ensayo de DHR, realizado por primera vez en Paraguay. También se obtuvo información sobre los posibles patrones de herencia, EGC-LX en dos familias y un caso probable de EGC-AR.

Directed formation of fertility of soils in Non-Chernozem region, taking into account the potential capabilities of arable crops
Authors: Maximenko Vladimir , Volchkova Tatyana , Menshikova Snezana
Published: February 2020

The article considers the possibility of directed formation of soil fertility in the conditions of crop production by increasing the efficiency of accumulation of incoming solar energy by crops. The effect is provided by deep volumetric loosening with one-time intra-soil introduction of meliorant, cultivation of crop-meliorant and subsequent treatment of different depths of the reclaimed soil layer for agricultural crops rotation. Given that the root system of plants affects the physical and chemical properties of the soil, its deeper placement contributes to the enrichment of deep layers soil of nutrients. Directed formation of the root system in the likeness of its natural development in favorable conditions of structural addition provides natural deposition in its layers of elements available for subsequent crops.
Ataxia-telangiectasia mutated interacts with Parkin and induces mitophagy independent of kinase activity. Evidence from mantle cell lymphoma

Ataxia telangiectasia mutated (ATM), a critical DNA damage sensor with protein kinase activity,is frequently altered in human cancers including mantle cell lymphoma (MCL). Loss of ATM protein is linked to accumulation of nonfunctional mitochondria and defective mitophagy, in both murine thymocytes and in A-T cells. However, the mechanistic role of ATM kinase in cancer cell mitophagy is unknown. Here, we provide evidence that FCCP-induced mitophagy in MCL and other cancer cell lines is dependent on ATM but independent of its kinase function. While Granta-519 MCL cells possess single copy and kinase dead ATM and are resistant to FCCP-induced mitophagy, both Jeko-1 and Mino cells are ATM proficient and induce mitophagy. Stable knockdown of ATM in Jeko-1 and Mino cells conferred resistance to mitophagy and was associated with reduced ATP production, oxygen consumption, and increased mROS. ATM interacts with the E3 ubiquitin ligase Parkin in a kinase-independent manner. Knockdown of ATM in HeLa cells resulted in proteasomal degradation of GFP-Parkin which was rescued by the proteasome inhibitor, MG132 suggesting that ATM-Parkin interaction is important for Parkin stability. Neither loss of ATM kinase activity in primary B cell lymphomas nor inhibition of ATM kinase in MCL, A-T and HeLa cell lines mitigated FCCP or CCCP-induced mitophagy suggesting that ATM kinase activity is dispensable for mitophagy. Malignant B-cell lymphomas without detectable ATM, Parkin, Pink1, and Parkin-Ub ser65 phosphorylation were resistant to mitophagy, providing the first molecular evidence of ATM's role in mitophagy in MCL and other B-cell lymphomas.
uPA-mediated plasminogen activation is enhanced by polyphosphate
Authors: Claire S Whyte  , Nicola J Mutch
Published: February 2020

Tissue plasminogen activator (tPA) and urokinase (uPA) differ in their modes of action. Efficient tPA-mediated plasminogen activation requires binding to fibrin. In contrast, uPA is fibrin independent and activates plasminogen in solution or when associated with its cellular receptor uPAR. We have previously shown that polyphosphate (polyP), alters fibrin structure and attenuates tPA and plasminogen binding to fibrin, thereby down-regulating fibrinolysis. Here we investigate the impact of polyP on uPA-mediated fibrinolysis. As previously reported polyP of an average chain length of 65 (polyP65) delays tPA-mediated fibrinolysis. The rate of plasmin generation was also delayed and reduced 1.6-fold in polyP65-containing clots (0.74 ± 0.06 vs. 1.17 ± 0.14 pM/s in P < 0.05). Analysis of tPA-mediated fibrinolysis in real-time by confocal microscopy was significantly slower in polyP65-containing clots. In marked contrast, polyP65 augmented the rate of uPA-mediated plasmin generation 4.7-fold (3.96 ± 0.34 vs. 0.84 ± 0.08 pM/s; P < 0.001) and accelerated fibrinolysis (t1/2 64.5 ± 1.7 min vs. 108.2 ± 3.8 min; P < 0.001). Analysis of lysis in real-time confirmed that polyP65 enhanced uPA-mediated fibrinolysis. Varying the plasminogen concentration (0.125 to 1 μM) in clots dose-dependently enhanced uPA-mediated fibrinolysis, while negligible changes were observed on tPA-mediated fibrinolysis. The accelerating effect of polyP65 on uPA-mediated fibrinolysis was overcome by additional plasminogen, while the down-regulation of tPA-mediated lysis and plasmin generation was largely unaffected. PolyP65 exerts opposing effects on tPA- and uPA-mediated fibrinolysis, attenuating the fibrin cofactor function in tPA-mediated plasminogen activation. In contrast, polyP may facilitate the interaction between fibrin-independent uPA and plasminogen thereby accelerating plasmin generation and downstream fibrinolysis.

This study is preliminary in the development of a new model whereby combining and integrating an existing model, the adoption model of information technology with the technology acceptance model. The development of this model is done by using the logic of the IPO (input-process-output) and the causal model by combining, adopting, and adapting the previous model. The effect of the formed path consists of 16 links and produces 11 variables. The existing variables will be formed into 55 indicators, where one variable creates five indicators. The process of developing this model will assist researchers in testing the information technology adoption model and the technology acceptance model so that it will get the effect that occurs in both models. This research will also contribute to further research, especially in the study of information systems, which will provide a theoretical basis for modeling. Besides, the transparency of the development and proposed models, especially in the instruments used, will be taken into consideration in conducting further research .

The health of seagrass plants, and thereby the ecosystems they form, is linked to their associated microbial communities. However, the role of the microbiome in holobiont function and health remains poorly understood for most seagrass species and environmental pressures, and there is, therefore, a need to better understand the drivers behind the formation of and external influences on the seagrass microbiome. Using a core microbiome framework, we characterised the leaf microbiomes of 6 estuarine seagrass populations after a precipitation event to explore how the microbiomes vary across different sites and salinities over a regional spatial scale. We found that each estuary had distinct core bacterial community structures (beta-diversity), but shared a more similar fungal core community structure. We hypothesise that the differences in the bacterial members of the microbiomes among estuaries are generally the result of each estuary being influenced by unique watersheds and sources of prokaryotes. In contrast, the similarity in the core fungal communities suggests that the eukaryotic components of the microbiomes are likely under selection or result from similar colonisation pathway(s). We also found that the bacterial taxa driving the differences among estuaries were linked to the salinity of the estuary, likely due to (1) the general epibiotic nature of colonisation (i.e. watershed source and exposure) and (2) members or functional groups within the leaf microbiome assisting seagrasses in coping with the extreme salinities. These results are valuable for linking microbiomes to the resilience of seagrasses living within dynamic estuaries experiencing a range of physicochemical pressures.
Body size adaptions under climate change: zooplankton community more important than temperature or food abundance in model of a zooplanktivorous fish
Authors: Ljungström G , Claireaux M , Fiksen Ø , Jørgensen C
Published: February 2020

One of the most well-studied biogeographic patterns is increasing body size with latitude, and recent body size declines in marine and terrestrial organisms have received growing attention. Spatial and temporal variation in temperature is the generally invoked driver but food abundance and quality are also emphasized. However, the underlying mechanisms are not clear and the actual cause is likely to differ both within and among species. Here, we focused our attention on drivers of body size in planktivorous fish that forage through vision. This group of organisms plays a central role in marine ecosystems by linking the energy flow from lower to higher trophic levels. Using a model that incorporates explicit mechanisms for vision-based feeding and physiology, we investigated the influence on optimal body size of several biotic (prey size, prey energy content, and prey biomass concentration) and abiotic (temperature, latitude, and water clarity) factors known to affect foraging rates and bioenergetics. We found prey accessibility to be the most influential factor for body size, determined primarily by prey size but also by water clarity, imposing visual constraints on prey encounters and thereby limiting feeding rates. Hence, for planktivores that forage through vision, an altered composition of the prey field could have important implications for body size and for the energy available for reproduction and other fitness-related tasks. Understanding the complicated effects of climate change on zooplankton communities is thus crucial for predicting impacts on planktivorous fish, as well as consequences for energy flows and body sizes in marine systems.

Here we analyzed associations between muscles mass, total bone mineral content (BMC), lumbar spine bone density (BMD L1-L4) and serum or urine hormones in healthy peripubertal girls. Total BMC and areal BMD L1-L4, muscle mass and fat were measured by dual-energy X-ray absorptiometry (DXA). Muscle force (N) was estimated by a dynamometer. Circulating estradiol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), 25-hydroxy vitamin D, parathyroid hormone (PTH), insulin-like growth factor 1 (IGF-1), leptin, osteocalcin, bone isoenzyme of alkaline phosphatase (bALP) and total calcium and phosphorus were quantified as the nocturnal melatonin and serotonin urinary excretion. Partial correlations adjusted for height, Tanner score and physical activity confirmed positive relationships between BMC or BMD L1-L4 (Z-score) and lean mass or fat. Furthermore, positive relationship was observed between BMC or BMD L1-L4 (Z-score) and serum leptin. After adjustment for Tanner score and physical activity, positive associations were observed between lean mass and IGF-1, leptin levels or muscle force. We proved positive relationships between bone mass and serum leptin in peripubertal girls.
TÜRK İŞARET DİLİNDE GÖNDERİMSELLİK VE İŞARET ALANI
Authors: MAKAROĞLU Bahtiyar
Published: February 2020

Görsel-uzamsal modaliteye özgü farklılıkları ve sözdizim-anlambilim arakesitini bir araya getirerek bu çalışma, Türk İşaret Dilindeki (TİD) işaret alanının gönderimsel amaçlarla kullanılmasına odaklanmaktadır. TİD verisine dayanarak, kimlik uzayı ve eksiltili uzay (işaretçinin önündeki sınırlı alan)  arasındaki belirgin ayrımdan yola çıkarak işaret alanının kullanımının anlambilimsel çözümlenmesine ilişkin genel bir bakış sunmaktadır. TİD’de eksiltili alan hem gönderimsel (örn. söylem gösterimi) hem de gönderim-dışı birimler (örn. belirteç öbeklerindeki göstermeler) ile ilişkili olabilmektedir. Costello (2016)’yı takip eden çalışma, adın kendisi ve “gönderimsel çıkak” olarak adlandırılan uzamsal konum arasındaki ilişkiye yoğunlaşarak anlamsal gönderimsellikte [+kimlik] ϕ-özelliğinin özel rolünü tartışmaktadır. Ayrıca, TİD’de kimlik ϕ-özelliğinin AÖ’yü yöneten işlevsel bir başta yer aldığı öne sürülmektedir. Uzayın eşbiçimli haritanmasındaki çok belirgin benzerliklere rağmen, işaret dillerindeki gönderimsellik olgusunu çözümlemek için daha fazla karşılaştırmalı dilbilgisel veriyi dikkate almak gerçekten önemlidir.
User Trusts: Broad-Based Ownership for Online Platforms
Authors: Schneider Nathan
Published: February 2020

This essay introduces what promise a novel broad-based capital strategy—trusts serving platform users—might hold for the online economy, especially as an enabler of more widespread, organized, and democratic user accountability. It draws on lessons from the experience of employee ownership alongside emerging opportunities for other kinds of broad-based ownership structures. User-oriented trusts could enable meaningful co-governance and profit sharing among essential stakeholders, a prospect that merits research and experimentation.
Using Think-Alouds to Understand How Students Balance Free Speech and Inclusion
Authors: Bernstein Jeffrey , Armstrong Cameron
Published: February 2020

Higher education is increasingly under fire as a bastion of liberal intolerance, where freedom of expression is routinely curtailed to protect and coddle vulnerable individuals and foster inclusion. While much of this picture is exaggerated, recent evidence suggests there is some truth at the core of this claim. We explore student attitudes toward freedom of speech on campus using a think-aloud method, in which students are exposed to source material on a subject and “think aloud” as they work through it. We gain an in-depth picture of how students understand and make judgments about who should and should not be allowed to speak on campus. Students tend to be more restrictive than a civil libertarian might like, albeit in (usually) internally consistent and sympathetic ways. We conclude by suggesting interventions that could help students better understand the way First Amendment rights are typically adjudicated and balanced against other lofty goals.
SOTL Research Design for Assessment of Interventions

Published: February 2020

Faculty are becoming increasingly interested in the science of teaching and learning (SoTL) and working to explore whether specific interventions are associated with a substantive change in learning outcomes (Whitman and Richlin 2007). In this article we lay out different ways faculty might deepen their approach to SoTL through their courses, provide examples for and explanations of these designs, discuss different means of assessing outcomes depending on the types and regularity of courses faculty teach, and provide specific tools for assessment in the context of a Political Science methods course.
Political Knowledge and the Development of Civic Dispositions and Skills
Authors: Owen Diana
Published: February 2020

This study explores the proposition that knowledge of American government and politics is associated with heightened civic dispositions and skills. It find that quality civic education programs can increase civic knowledge, skills, and dispositions. Using middle and high school student data, the study establishes an empirical association between knowledge and dispositions, and to a lesser extent, civic skills. High-need students exhibited a strong connection between knowledge an dispositions. The association between knowledge and dispositions was stronger for high school students than for middle school students.
Evaluating a Donor-Funded Reproductive Rights Experiential Learning Program
Authors: Daniel Clare
Published: February 2020

This paper discusses the characteristics, learning objectives, challenges, and outcomes of a donor-funded internship program for undergraduate students interested in reproductive rights, health, and justice at Tulane University’s Newcomb Institute. I argue that this model, while it has unique challenges, is well-suited to meet the objectives typically established for service-learning programs, including the development of authentic, mutually beneficial, sustainable relationships between community partners and the university (James and Logan 17) and the cultivation of students’ senses of self-efficacy and interest in community engagement (Knapp et al.).
