Development of an improved wheel profile for a freight car. Theoretical justification
Authors: Orlova A. M. , Savushkin R. A. , Fedorova V. I.
Published: November 2018

With the increasing loads on the axle and speeds, the increase in wear resistance and resistance to contact fatigue of the wheels is of particular importance. In part, this result was achieved using a standard profile according to GOST 10791–2011 with the use of more efficient spring suspension. A further reduction in the wear rate of both the rolling surface and the flange can be achieved by developing a new wheel profile.

The authors have developed a technique that allows, based on theoretical calculations and experimental observations, to make the choice of the shape of the wheel profile, consistent with the profiles of the rails. The results of measurements of the wheels of cars of the model 12-9853 installed on bogies 18-9855 were used as the initial data, which were under controlled operation. The profile development consisted of four main stages: the choice of baseline data, the choice of the curvature of the rolling surface, the choice of the curvature of the transition section to the throttle, and the choice of the flange thickness and radius of the throttle in the transition zone to the rolling surface.

The technique was used to develop a new wheel profile that differs from the profile according to GOST 10791–2011 in that the rolling surface is made with three conjugate radii, respectively from the wheel to the flange: 500, 325 and 87.5 mm. The flange throttle radius of the developed profile is 17 mm, the angle of inclination of the flange to the horizontal is 68°, and the thickness of the flange is 32.5 mm. A part of the wheel surface from the wheel to the outer part of the rim fully complies with GOST 10791–2011. Calculations showed that the contact zone of the wheel with the VNITsTT profile relative to the rail is shifted from the center to the flange and the contact area is larger. It was found that for the VNITsTT wheel profile the ratio of the semi-axes of the ellipse of contact spots is lower than for the profile according to GOST 10791–2011.

Published: November 2018

La composición y diversidad de las lagartijas son influenciadas por el tipo de vegetación, debido a que éste determina la estructura física y ambiental de sus hábitats. El objetivo de este estudio fue determinar y analizar la diversidad taxonómica de las lagartijas del área prioritaria de conservación Sierra El Cuale, Jalisco, México, asociada a cuatro tipos de vegetación: bosque tropical subcaducifolio (BT), bosque de encino (BE), bosque de pino-encino (BPE) y bosque de pino (BP). Se realizaron muestreos mensuales entre julio de 2015 y junio de 2016. Se registró una riqueza total de 12 especies en el área de estudio: ocho en BT, nueve en BE, seis en BPE y seis en BP. Las curvas de acumulación de especies mostraron que se requiere más esfuerzo de muestreo para caracterizar en su totalidad a la comunidad de lagartijas. Anolis nebulosus, Sceloporus melanorhinus y S. utiformis se observaron en los cuatro tipos de vegetación, pero Basiliscus vittatus, Gerrhonotus liocephalus y Scincella assatus solo en uno. Un análisis de escalamiento multidimensional no métrico (NMDS) identificó dos grupos según la presencia de especies de lagartijas y estaciones del año (lluvias y seca): BPE-BP y BT-BE. La distintividad taxonómica promedio (Δ+) y la riqueza de especies fueron altas en la estación lluviosa. Los resultados de este estudio muestran que la riqueza de especies de lagartijas en la Sierra El Cuale está vinculada a la variedad de tipos vegetación. Por otro lado, el análisis comparativo de la Δ+ entre la Sierra El Cuale y las Reservas de la Biosfera de Chamela-Cuixmala y Manantlán, mostró que la Sierra El Cuale tiene un papel importante en la contribución regional de la diversidad de lagartijas.

Se reportan cuatro subfamilias, 17 géneros y 22 especies de Tettigoniidae; de éstos, 11 son nuevos registros para el Estado de Hidalgo. El índice de Shannon mostró que el área de estudio presenta una diversidad elevada y uniforme: Bosque de Encino (BE) H´=2.78, Selva Media (SM) H´=2.23 y Bosque Mesófilo de Montaña (BMM) H´=2.13. La subfamilia Phaneropterinae mostró la mayor abundancia (N) con 103 individuos, que representan el 53% del total de ejemplares recolectados (195). Esta subfamilia mostró también la mayor riqueza (S) con 67% (14 taxa) del total de especies (22) recolectadas. El índice de Sorensen, modificado por Bray Curtis mostró que la similitud en la composición faunística entre los ecosistemas es la siguiente: BE-SM (0.36), SM-BMM (0.49) y BMM-BE (0.33). El Índice de Morisita-Horn dio como resultado una similitud de 77 % entre BE-SM, 62 % entre SM-BMM y 76 % entre BE-BMM. Tanto N como S mostraron una relación negativa en referencia al gradiente altitudinal, lo cual ocurre en otros grupos de insectos.

Published: November 2018

La invasión de la paloma turca (Streptopelia decaocto) a través del país es un proceso creciente y vigente. Dado el posible impacto de su presencia sobre la biodiversidad y salud pública, es primordial conocer su estatus de permanencia (establecimiento, tamaño poblacional y patrones de dispersión) y sus interacciones bióticas en los sitios en los que está presente. En este trabajo se estimó su densidad al inicio y fin de una temporada reproductiva en la ciudad de Morelia y se registró el uso de sustratos que utilizó para posarse. Se utilizaron transectos de largo variable para calcular la densidad de la especie y se registró el sustrato en el que estaba posado cada individuo observado. El incremento de la densidad de la especie fue significativo, sin embargo, la distribución de S. decaocto al interior de la ciudad no fue homogénea ya que existieron transectos que concentraron hasta el 82% de los registros. Además, se documentó que S. decaocto presentó un cambio significativo en el uso de Casuarina equisetifolia como sustrato entre el inicio y el fin de la temporada reproductiva. Asimismo, se presentó evidencia de eventos de anidación de la paloma turca, confirmando el establecimiento de la especie en la ciudad de Morelia. Es importante y necesario incrementar el conocimiento que tenemos de esta especie a escala local, pues permitiría una mejor planeación de control y/o erradicación de esta especie exótica e invasora.

Published: November 2018

En este estudio comparamos aspectos ecológicos del uso del microhábitat y periodo de actividad de una comunidad de anuros en cuatro tipos de vegetación (bosque tropical caducifolio, bosque de galera, matorral xerófilo y pastizal inducido) en un ambiente tropical estacional de la región suroeste del estado de Guanajuato, en el Área Natural Protegida Las Musas. Se registraron nueve especies de anuros, tres de sapos y seis de ranas, de las cuales la más abundante fue Lithobates neovolcanicus (152 individuos), y las menos abundantes, con un solo individuo Craugastor occidentalis y Spea multiplicata. Se caracterizaron 17 distintos tipos de microhábitats, con diferencias entre especies (H = 0.22; P = 0.01) en cuanto a su uso. Los tipos de vegetación con la mayor heterogeneidad de microhábitats fueron el bosque tropical y el bosque de galería, en comparación con el matorral xerófilo y pastizal. Las especies que usaron más microhábitats fueron L. neovolcanicus, Anaxyrus compactilis y Dryophytes eximius. El mayor solapamiento se registró entre A. compactilis e Incilius occidentalis con el 100 %; para I. occidentalis y D. arenicolor fue de 89 % y para I. occidentalis y L. neovolcanicus de 72 %. Los periodos de actividad más prolongados se registraron en A. compactilis (10:28 a 22:10 hrs) y L. neovolcanicus (10:40 a 22:20 hrs). Se encontró una relación positiva entre la temperatura corporal y la temperatura del microhábitat y la ambiental para A. compactilis, I. occidentalis, D. eximius, D. arenicolor, y L. neovolcanicus. La comunidad de anuros presente en el área de estudio puede diferenciarse en tres componentes eco-estructurales, conforme a sus hábitos; especies acuáticas, saxícolas-terrestres y arborícolas, determinados tanto por sus hábitos para la selección de microhábitats, como por sus periodos de actividad diarios. Consideramos que si bien, la heterogeneidad vegetal es importante en la distribución de las especies y disponibilidad de microhábitats, no es el principal factor en la selección y uso de los microhábitats por parte de las especies como se suponía. Sino que la selección y uso de los microhábitats y composición de la comunidad de anuros, se determinó por eventos conductuales que se manifiestan en los periodos de actividad y capacidad de termorregular de cada especie, como una respuesta de orden fisiológico a la influencia de la temperatura.

Published: November 2018

Background: Coronary heart disease (CHD) is still the leading cause of death in the world. There are various risk factors for atherosclerosis leading to CHD. Duke Treadmill Score (DTS) is known to demonstrate prognostic stratification and has a diagnostic value in predicting the number of coronary arteries involved in patient populations with ischemic heart disease. However, DTS does not describe the role of risk factors for coronary heart disease to the complexity of coronary artery lesions. This study aims to add risk factors for coronary heart disease on DTS to detect the complexity of coronary artery lesions with stable angina pectoris.Methods: This study was a cross-sectional study in stable angina pectoris patient who comes to Haji Adam Malik Hospital Medan from January 2017 until February 2018. Patients who have done treadmill test and coronary angiography, and fulfill inclusion and exclusion criteria are included in the study. ECG examination and recording of risk factors for coronary heart disease were done. DTS assessment was performed based on a treadmill test and Syntax score based on coronary angiography results. Diagnostic tests were performed to assess the sensitivity and specificity of the addition of CHD risk factors to detect the complexity of coronary artery lesions.Results: Of the 76 people with stable angina pectoris, 55 people were found with low SYNTAX and 21 people with high Syntax. DTS is divided into 3 groups: mild (> -10), moderate (-10 to - 13.5), and severe (≤-13.6) based on the cut off of the ROC curve. Risk factors for CHD are divided into 3 groups, mild (≤3 CHD risk factors), moderate (4-6 CHD risk factors), and severe (7 CHD risk factors) based on the cut off of the ROC curve, then assessed the relationship with Syntax which has been divided into 2 groups, low Syntax, and high Syntax. Diagnostic test shows the addition of risk factors of CHD to DTS to detect the complexity of coronary artery lesions have greater sensitivity and specificity than DTS without the addition of risk factors of CHD, 95%, and 89%.Conclusion: The addition of risk factors for coronary heart disease on DTS can detect the complexity of coronary artery lesions.

Published: November 2018

Background: Triglycerides (TG) as a risk factor for coronary artery disease (CAD) is still a matter of controversy but when used as a single ratio with high density lipoprotein (HDL) the predictive value for CAD is better. The TG/HDL ratio is also associated with the presence of small dense LDL (sdLDL) in the body. SdLDL is a more atherogenic LDL subfraction and has been proven to be associated with CAD progression.Aims: This study aims to find the correlation between the TG/HDL ratio and the degree of coronary lesion severity based on the Gensini score in stable non diabetic angina pectoris patients.Methods: This study was a cross sectional study conducted at Dr. Hasan Sadikin Hospital and Hasna Medika Palimanan Hospital. Subjects were non diabetic stable angina pectoris patients ≥18 years old who underwent elective coronary angiography. Blood collection for TG and HDL examination was performed after coronary angiography. Gensini scoring system was used to assess the severity of coronary lesions. The relationship between the TG/HDL ratio and the Gensini score was analyzed using multiple linear regression tests against confounding variables.Results: This study involved 60 patients with stable angina pectoris with a mean age of 60±8 years. The mean TG/HDL ratio is 2.56 ± 1.04. The average Gensini score was 51 ± 36. The TG/HDL ratio was significantly associated with the Gensini score (R = 0.637; p <0.001). Analysis of confounding variables showed age, hypertension, and metabolic syndrome had a weak correlation with Gensini score (r values of 0.321, 0.270, and 0.333, p <0.05, respectively), while those correlating with TG/HDL ratios were men, hypertension, and metabolic syndrome (r values of 0.290, 0.287, and 0.362, p <0.05, respectively).Conclusion: TG/HDL ratio was significantly positively correlated significantly with the severity of coronary lesions based on Gensini score in non diabetic stable angina pectoris patients.

Published: November 2018

Purple Dioscorea alata is one kind of tuber crops that rich in polyphenolic compounds. In Indonesia, the utilization of this yam is still very limited because it is easily damaged on the fresh form. Due to its high perishability, then the fresh tuber have to be processed into dried materials to expand its utilization. This study investigated the effect of browning inhibition treatments (immersion in water, Na-bisulfite, and ascorbic acid) on moisture, color, anthocyanin, flavonoid and phenolic content, and determined the antioxidant activities of D. alata flour. The moisture content of D. alata flour ranged between 6.89 to 7.71% db, which still in the range of wheat flour moisture content standards using Codex Standard. Browning inhibition treatment improved the color appearances and provided better values on anthocyanin, phenolic, and flavonoid content of D. alata flour. The color and antioxidant activities of D. alata flour were significantly correlated with its functional properties.
Clinical Pharmacology of Antihypertensive Therapy for the Treatment of Hypertension in CKD
Authors: Sinha Arjun D. , Agarwal Rajiv
Published: November 2018

CKD is common and frequently complicated with hypertension both predialysis and in ESKD. As a major modifiable risk factor for cardiovascular disease in this high-risk population, treatment of hypertension in CKD is important. We review the mechanisms and indications for the major classes of antihypertensive drugs, including angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, β-adrenergic blocking agents, dihydropyridine calcium channel blockers, thiazide diuretics, loop diuretics, mineralocorticoid receptor blockers, direct vasodilators, and centrally acting α-agonists. Recent evidence suggests that β-adrenergic blocking agents may have a greater role in patients on dialysis and that thiazide diuretics may have a greater role in patients with advanced CKD. We conclude with sharing our general prescribing algorithm for both patients with predialysis CKD and patients with ESKD on dialysis.

Published: November 2018

This study examined the effect of live Lactobacillus paracasei NFRI 7415 on the preference of a lard diet (LD) and a fish-oil diet (FD) in rats. 4-week-old male Fischer 344 rats were fed one of four diets; LD, LD + lactic acid bacteria (LLD), FD and FD + lactic acid bacteria for 4 weeks (dietary experimental period). The LLD and FLD groups freely ingested water containing Lb. paracasei NFRI 7415 (107 cfu/ml). After 4 weeks, all rats were placed on a two-choice diet program in which they self-selected from two food cups, each containing either the LD or the FD for 5 weeks (self-selection period). After the dietary experimental period, there was no significant difference in the final body weight and total food intake among the four groups. The intake of fish-oil and live Lb. paracasei NFRI 7415 was increasing the fecal lipids excretion, and it effectively reduced plasma total cholesterol concentration (p<0.05). It was indicated that the intake of live Lb. paracasei NFRI 7415 was no influence on the preference for fat in the dietary experimental period and the self-selection period.

Published: November 2018

En este artículo se proponen reflexiones sobre los modos en que las escuelas incorporan el uso de medios digitales en las aulas en Argentina y México. En primer lugar, se presentan consideraciones teóricas sobre los vínculos entre tecnologías y escuelas; la perspectiva adoptada enfatiza que las tecnologíasdigitales son medios que registran y organizan la experiencia humana de formas particulares, y que las escuelas son ensamblajes heterogéneos, negociados e impulsados por los actores que las componen. El segundo apartado refiere los cambios y nuevas condiciones que los medios digitales introducen en la escolarización, y el tercero despliega parte de los análisis producidos en el marco de varias investigaciones sobre usos de medios digitales en las escuelas referidas. Los argumentos presentados subrayan la dimensión artefactual e infraestructural de la cultura, y que los medios digitales ofrecen posibilidadesen conflicto, opciones y tensiones que dependen de cómo se inscriben en contextos específicos.

Published: November 2018

Date palm (Phoenix dactylifera L.) is the most important crop in the dry areas of the Middle East and North Africa. This palm has been introduced to many countries but has not been grown commercially in Indonesia. Date palm propaga-tion by seeds is easy but its progenies are varied and a half of them are male trees that will not produce fruits. Meanwhile, the propagation by offshoots is impractical and technically difficult. Tissue culture makes it possible to massproduce of genetically identicalsuperior date palms. This research aimed to develop somatic embryogenesis (SE) of date palm using shoot tipand young leaves of date palm seedling as explants. Steps on somatic embryogenesis are explant sterilization, callus initiation and proliferation, somatic embryos induction and maturation, and plantlets matura-tion and rooting. Calli emerged from shoot tip explants after  9 weeks of culture in a modified MS medium supplemented with 10 mg/L 2,4-D, 1 mg/L or  3 mg/L 2-iP, and 1.5 g/L active charcoal. The callus was able to bear somatic embryo in the modified MS medium without hormones. Somatic embryos then developed into plantlets, and roots of plantlets were effectively initiated in the medium supplemented with 0.5 mg/L NAA and 1 mg/L IBA.[Keywords:sterilization,  callogenesis, somatic embryo induction, plantlet rooting, clonal propagation]. Abstrak  Tanaman kurma (Phoenix dactyliferaL.) merupakan tanaman terpenting di wilayah kering Timur Tengah dan Afrika Utara.

Authors: Sabo Marlis T , Mahdi Fatima , Clark Marcia
Published: November 2018

Introduction: Rapid surgical management of hip fracture patients is critical to reduce morbidity and mortality.  These patients may be anti-coagulated and the new direct oral anticoagulants (DOAC) may introduce delays to treatment.  Our purpose was to examine the impact of these DOAC on time to surgical management for hip fracture patients.Methods: A prospective audit of 55 consecutive operative hip fracture patients examined time from diagnosis to surgery. Indications for anticoagulation were recorded.Results: Time to surgery for the DOAC group was 66±16 hours, versus 38±21 and 25±19 hours for warfarin and control groups, respectively (P<0.05). Anticoagulation was for atrial fibrillation in 93%.Conclusion: Patients on DOAC faced significant delays to surgery. Given that both DOAC use and incidence of hip fracture are expected to rise, this presents a barrier to optimized care in this vulnerable group.

Ecologia em revistas: análise de conteúdo das revistas "Veja" e "IstoÉ" nas décadas de 1970 a 1990
Authors: Barros Antonio Teixeira de
Published: November 2018

Analisa o conteúdo informativo de matérias jornalísticas sobre meio ambiente, publicadas pelas revistas Veja e IstoÉ, nas décadas de 1970 (Eco 72) a 1990 (Eco 92). Os temas que mais se destacam são: poluição, Amazônia, estudos ecológicos e devastação. A tendência de ambas as revistas é priorizar a cobertura de temas ligados ao contexto urbano, além dos chamados "temas globais", como mudanças climáticas, efeito estufa, ecoturismo e espécies ameaçadas de extinção.
Os estudos de recepção e as relações de gênero: algumas anotações provisórias
Authors: D. Escosteguy Ana Carolina
Published: November 2018

O trabalho trata da incorporação da categoria de gênero pelos estudos de recepção na América Latina.  Esses estudos estão adotando a categoria de gênero, fundamentalmente, para indicar uma distinção sexual entre feminino e masculino, isto é, como uma variável sócio-demográfica. Em outros casos, a mesma categoria pode até ser associada a papéis sociais - por exemplo, mãe, dona-de-casa -, mas essas atuações específicas não contribuem para explicar certos processos sociais e seus resultados objetivos. Enfim, o propósito é apresentar algumas anotações que subsidiam uma das premissas da investigação que atualmente estou desenvolvendo.

A dinâmica dos atos de linguagem em listas de discussão
Authors: Ferreira Jairo
Published: November 2018

Aparentemente, a questão chave da cooperação é o reconhecimento mútuo dos interlocutores. Essa hipótese é parcialmente válida, desde que este reconhecimento não seja visto como uma decorrência direta de um contrato. A questão do reconhecimento ultrapassa o contrato formal de lugares institucionais, para se sustentar em outras instâncias da vida social, além do compartilhamento, reciprocidade e conservação das proposições através de atos de linguagem, das representações concretas e da prática. Nesse sentido, as interações discursivas constituem-se numa sucessão de estruturas  instáveis e estáveis encadeadas entre si, o que implica em formas de equilíbrio (e, portanto, de cooperação) específicas em redes digitais.

A gestão democrática rumo ao óbito: o assédio moral em uma escola pública
Authors: Daud Rafael Petta , Teixeira Lidiane Aparecida
Published: November 2018

A partir da problemática “assédio moral nas relações de trabalho”, esta investigação, um estudo de caso, objetiva verificar se ela se manifesta no contexto de uma escola pública municipal de educação infantil situada em Ribeirão Preto/SP, assim como analisar seus possíveis efeitos no corpo docente em duas instâncias da ordem do psiquismo: as representações e seus afetos contingentes. O diagnóstico por nós confirmado destoa dos pressupostos normativos estruturantes da concepção de gestão democrática do ensino, mencionados de modo explícito na legislação brasileira da educação.
Um olhar sobre o letramento sob a abordagem High/Scope
Authors: Amorim-Vanderlei Kariny Louizy , Lira Thainy Kléia , Minervino Martha Maria
Published: November 2018

Este artigo destina-se à descrição e reflexão sobre uma experiência em educação infantil realizada em uma instituição pública de ensino de Alagoas. Tomando por base a abordagem educacional americana High/Scope no estudo, será tematizada a articulação entre elementos desta abordagem e os processos de letramento. Partindo- -se de uma concepção de aprendizagem pela ação – foco do currículo High/Scope – é proposta uma análise do ‘brincar de faz-de-conta’ dentro da perspectiva do letramento, apontando-se assim as contribuições deste entrelaçamento para o desenvolvimento da linguagem na criança.
Militarização e Escola sem Partido: duas faces de um mesmo projeto
Authors: Santos Catarina De Almeida , Da Silva Pereira Rodrigo
Published: November 2018

O artigo debate o processo de militarização das escolas públicas brasileiras e o movimento/projeto “escola sem partido”, apontando que ambos fazem parte de um projeto hegemônico e conservador que coloca em risco direitos fundamentais e preceitos constitucionais, dentre eles, os direitos sociais e, mais especificamente, o direito à educação e seus princípios, como definidos e defendidos na Constituição Federal de 1988 e na atual Lei de Diretrizes Bases de Educação Nacional.
Base Nacional Comum Curricular: ponto de saturação e retrocesso na educação
Authors: Cássio Fernando L.
Published: November 2018

A Base Nacional Comum Curricular (BNCC) é hoje o centro gravitacional das políticas do Ministério da Educação. Neste texto procuro construir a tese de que a BNCC representa um grave retrocesso na educação brasileira, ponto de saturação de um projeto de centralização curricular iniciado há mais de 20 anos, com os Parâmetros Curriculares Nacionais. Também exploro alguns elementos recentes do processo de “implantação” da Base, que ocorre simultaneamente dentro e fora do Estado, sublinhando que a complexidade desses processos desafia eventuais ações de resistência organizada à BNCC.

PEMETAAN DAERAH RAWAN LONGSOR DI SEKITAR DAERAH PROSPEK PANAS BUMI PROVINSI JAWA BARAT
Authors: Handayani Linda , Singarimbun Alamta
Published: November 2018

Eksplorasi potensi panas bumi diklaim sebagai tambang ramah lingkungan, maksudnya tidak terlalu banyak merusak dan tidak terlalu membahayakan lingkungan. Sejatinya benar, namun daerah panas bumi selalu berafiliasi dengan topografi yang sangat kasar, lerengnya terjal, dan jarang dijumpai tanah datar yang luas. Hal ini menyebabkan daerah di sekitar panas bumi rawan terhadap tanah longsor. Jenis batuan yang mudah lepas-lepas, membuat tingkat kerawanan terhadap kemungkinan tanah longsor semakin meningkat. Mengingat daerah panas bumi adalah daerah yang rawan terhadap bencana tanah longsor, maka perlu dilakukan pemetaan daerah rawan longsor untuk meminimalkan korban dan kerugian akibat bencana tersebut. Berdasarkan analisis menggunakan metode probabilistik frekuensi rasio, di sekitar daerah WKP panas bumi,  28,71% adalah daerah yang sangat rawan terhadap bencana longsor, 56,23% masuk dalam kategori rawan longsor, dan hanya 15,06%  saja daerah yang aman terhadap bencana longsor tersebut.

Published: November 2018

Penelitian ini mensimulasikan persamaan diferensial parsial konduksi panas 1-D untuk memprediksi model distribusi temperature jaringan biologis sapi seperti kulit, lemak, tumor dan otot selama penyerapan radiasi Terahertz sebagai fungsi posisi pada ke dalaman dan sebagai fungsi waktu dari milidetik sampai pikodetik. Pemodelan pola-pola temperature jaringan dari penyerapan radiasi Terahertzdikaji secara teoritis dengan metode komputasi biofisika menggunakan software Wolfam Mathematica 9. Penggunaan parameter-parameter fisis konduksi panas pada ke dalaman jaringan biologis sapi dari 0,1 mm sampai 0,3 mm, dan daya penyerapan radiasi Terahertz dari 2,5 mW sampai 5,5 mW dengan rentang frekuensi dari 0,1 THz sampai1THz. Hasil radiasi ini mengindikasikan penyerapan radiasi Terahertz dengan variasi daya yang memiliki karakteristik tersendiri dalam waktu milidetik sampai pikodetik. Daya penyerapan radiasi Terahertz yang besar dan waktu yang besar akan menghasilkan temperatur yang tinggi pada masing-masingjaringan bilogis sapi. Temperatur sebagai fungsi ke dalaman dipengaruhi oleh kandungan air di dalam jaringan biologis sapi, kandungan air penyusun jaringan yang kental pada waktu yang besar akan menghasilkan temperatur yang kecil. Perbandingan diantara pemodelan dan eksperimen menunjukkan bahwa prediksi temperatur transfer panas radiasi Terahertz cukup akurat dengan ketidakpastian kesalahan penyebaran untuk parameter-parameter yang diturunkan sebesar 0,8 %.
WASH Regulates Glucose Homeostasis by Facilitating Glut2 Receptor Recycling in Pancreatic β-Cells
Authors: Ding Li , Han Lingling , Dube John , Billadeau Daniel D.
Published: November 2018

WASH is an endosomal protein belonging to the Wiskott-Aldrich syndrome protein superfamily that participates in endosomal receptor trafficking by facilitating tubule fission via activation of the ubiquitously expressed Arp2/3 complex. While several studies have begun to elucidate an understanding of the functions of WASH in cells lines, the in vivo function of WASH has not been fully elucidated, since total body deletion in mice leads to early embryonic lethality. To circumvent this problem, we have used a WASH conditional knockout mouse model to investigate the role of WASH in the pancreas. We find that pancreas-specific deletion of WASH leads to impaired blood glucose clearance and reduced insulin release upon glucose stimulation. Furthermore, WASH depletion results in impaired trafficking of Glut2 in pancreatic β-cells as a consequence of an intracellular accumulation of Glut2 and overall decreased levels of Glut2 protein. Taken together, these results indicate that WASH participates in pancreatic β-cell glucose sensing and whole-body glucose homeostasis. Thus, patients harboring mutations in components of the WASH complex could be at risk for developing type 2 diabetes.

Sustained and rapid loss of glomerular filtration rate (GFR) is the predominant clinical feature of diabetic kidney disease and a requisite for the development of end-stage renal disease. Although GFR trajectories have been studied in several cohorts with diabetes and without diabetes, whether rapid renal decline clusters in families with diabetes has not been examined. To determine this, we estimated GFR (eGFR) from serum creatinine measurements obtained from 15,612 patients with diabetes at the University of Utah Health Sciences Center and established their renal function trajectories. Patients with rapid renal decline (eGFR slope < −5 mL/min/1.73 m2/year) were then mapped to pedigrees using extensive genealogical records from the Utah Population Database to identify high-risk rapid renal decline pedigrees. We identified 2,127 (13.6%) rapid decliners with a median eGFR slope of −8.0 mL/min/1.73 m2/year and 51 high-risk pedigrees (ranging in size from 1,450 to 24,501 members) with excess clustering of rapid renal decline. Familial analysis showed that rapid renal decline aggregates in these families and is associated with its increased risk among first-degree relatives. Further study of these families is necessary to understand the magnitude of the influence of shared familial factors, including environmental and genetic factors, on rapid renal decline in diabetes.
