In Brazil, milk kefir, made of milk kefir grains, has identity features defined by Brazilian regulatory agencies but sugary water kefir, made of water kefir grains, has no definition of microbiological and physicochemical standards. We evaluated the microstructure of Brazilian milk and water kefir grains, the Transcriptionally Active Microbiome (TAM) of kefir beverages made of them, and the effect of fermentation and storage period (28 days at 10oC) over microbiological and physicochemical features of these beverages. Milk and water grains are very different between them and similar to other kefir grains worldwide, macroscopically and microscopically. The genus Leuconostoc, with the species L. mesenteroides, was most frequent in the microbiome of milk kefir while the Oenococcus genus was most frequently seen in sugary water kefir, with the species O. kitaharae. The genera Saccharomyces and Torulaspora, with the species S. cerevisiae and T. delbrueckii, were most recurrent in the microbiome of sugary water kefir, while Pichia and Yarrowia were more abundant in milk kefir, with the species P. fermentans and Y. lipolytica. Microbiological and physicochemical parameters of milk kefir were in concordance with features defined by Brazilian legislation. None of the parameters was altered by cold storage for 28 days. Our results reinforce some Brazilian identity requirements for milk kefir and allow us to suggest the inclusion of new ones that are not defined yet. Regarding sugary water kefir, some microbiological and physicochemical parameters are similar to milk kefir during the same storage period, although with a quite different functional microbiome.

Objectives: To determine the relationship between anterior segment parameters and the optic nerve head (ONH) parameters of females. Methods: Anterior segment, optic nerve head parameters, Intraocular Pressure (IOP) and Axial Length (AL) of 99 participants (aged 20.1±1.3 years) were obtained. Differences between refraction groups and relationship between anterior segment and ONH parameters were assessed as well as linear regression for factors associated with ONH and anterior segment parameters after adjusting for cofounders. Results: SER (-0.12 Acknowledgements: The authors acknowledge the support of the Research Centre, of the Female Scientific and Medical Colleges, Deanship of Scientific Research at King Saud University.0.58D), AL (23.5±0.8 mm), IOP (17.8±2.0 mmHg), anterior segment parameters and optic disc parameters were similar between refraction groups (p>0.20 for all). Age was correlated with anterior chamber volume (r=-0.19), while SER was correlated with AL (r=-0.26), anterior chamber volume (r=-0.25) and angle (r=- 0.19) and with the disc area (r=0.25; p<0.02 for all). Myopes had wider anterior chamber depths than emmetropes (mean difference, 2.06, 95% confidence interval: 0.32/3.80 degs, p=0.02) with smaller disc area (-0.21mm², 95% CI: -0.38/-0.03mm²; p=0.021). After correcting for age and refraction, axial length was associated with corneal refractive power (r=-0.60, p<0.001), and anterior segment parameters (p<0.001 for all). Conclusions: The ONH structure was related to anterior segment morphology including corneal thickness, anterior chamber volume and depth, which is important when interpreting OCT imaging.

Published: May 2021

We present a simple scheme to extract the adsorption energy, adsorbate interaction parameter and the saturation coverage from temperature programmed desorption (TPD) experiments. We propose that the coverage dependent adsorption energy can be fit using a functional form including the configurational entropy and linear adsorbate-adsorbate interaction terms. As one example of this scheme, we analyze TPD spectra of desorption on Au(211) and Au(310) surfaces. We determine that under atmospheric pressure, the steps of both facets adsorb between 0.4-0.9 ML coverage of CO*. We show this result to be consistent with density functional theory calculations of adsorption energies with the BEEF-vdW functional.
ОПТИМИЗАЦИЯ РЕЖИМА ОСАЖДЕНИЯ БЕЛКОВ ПРИ ОПРЕДЕЛЕНИИ МОЛЕКУЛ СРЕДНЕЙ МАССЫ КАК МАРКЕРА ЭНДОГЕННОЙ ИНТОКСИКАЦИИ

Published: May 2021

Синдром эндогенной интоксикации (СЭИ) часто встречается в клинической практике, его маркеры используются в качестве критериев, определяющих тяжесть состояния больного и прогноз болезни. Многообразие современных лабораторных критериев, характеризующих тяжесть СЭИ, а также позволяющих определять динамику токсичности компонентов внутренней среды, не всегда доступны по причине сложности и высокой стоимости исполнения. В данном ключе часто используют общепринятый интегральный маркер метаболических нарушений - молекулы средней массы (МСМ). Различия в некоторых методических приемах и использование трихлоруксусной кислоты в качестве осадителя дают ложные результаты, искажая реальную величину поглощения в диапазоне максимума оптического поглощения веществ, имеющих в составе связи N-H, и обладающих диагностической ценностью при оценке СЭИ. В работе представлено обоснование модификации общепринятого метода определения МСМ путем изменения осаждающего агента на хлорную кислоту. В предложенном нами варианте исследования МСМ предоставляется возможным оценивать содержание как низкомолекулярных пептидов, так и гликопептидов. Изучение динамики их накопления дает клинически значимую информацию, необходимую для раннего распознавания и мониторинга тяжести разнообразных патологических состояний, в том числе СЭИ.
Proteksionisme Trump dan Masa Depan Supremasi Politik AS
Authors: Sahide Ahmad
Published: May 2021

Donald Trump, Presiden Amerika Serikat, sudah menunjukkan arah kebijakan inward-looking atau proteksionisme sejak awal kampanyenya menuju White House. Sebagai presiden dengan latar belakang pengusaha, Trump melihat bahwa pasar bebas dengan membiarkan semua berjalan sesuai dengan mekanisme pasar lebih banyak merugikan Amerika Serikat. Oleh karena itu, bagi Trump, rakyat Amerika membutuhkan kehadiran negara untuk melindungi (proteksi) produk yang dihasilkan dalam menghadapi produk-produk yang datangnya dari luar (produk impor). Pandangan ‘America First’ Trump inilah yang memunculkan gejolak politik global. Tidak lama setelah menjadi Presiden AS, Trump akhirnya menepati janjinya dengan mengeluarkan peraturan tarif bagi produk impor, terutama yang datang dari China dan Meksiko. Hasil dari kajian ini menunjukkan bahwa kebijakan proteksionisme yang diambil oleh Trump tersebut memicu terjadinya perang dagang karena China, sebagai salah satu negara super power, tidak berdiam diri. China membalas kebijakan Trump dengan tarif yang tinggi untuk produk impor yang datang dari Amerika Serikat. Perang Dagang pun menjadi tidak terhindarkan dan hal ini memengaruhi gejolak ekonomi global. Dampak dari perang dagang yang dipicu oleh kebijakan inward-looking Trump ini adalah sekutu AS di Eropa, yang menganut ekonomi liberal pun mulai tidak sejalan dengan langkah politik Trump sehingga hal ini mengancam supremasi politik AS dalam kancah politik global. Di satu sisi, China kini sedang bangkit dan diprediksi bahwa negara Tirai Bambu tersebut akan menggantikan supremasi politik global Amerika Serikat. Keberanian China dalam melayani AS di bawah Trump dalam perang dagang mengindikasikan bahwa AS bukan lagi negara yang memegang kendali dunia sepenuhnya. Maka, supremasi politik global Amerika dalam ancaman. China adalah salah satu negara yang menjadi ancaman nyata dan di depan mata.

A Educação Ambiental constitui uma forma bastante abrangente de “educar” e deve acontecer por meio de processos onde a indivíduo e a coletividade construam valores sociais, conhecimentos, habilidades, atitudes e competências voltadas para a conservação do meio ambiente. Na área de saneamento básico a educação ambiental desempenha um papel de grande importância, uma vez que a falta do conhecimento e habilidades adequadas geram sérios malefícios para a saúde e o bem-estar da população. No presente trabalho foi executado e avaliado um método alternativo para tratamento de efluente doméstico, ideal para comunidades distantes de centros urbanos e sem sistema de tratamento de esgoto. Através dos resultados alcançados, juntamente das informações técnicas apresentadas foi possível pensar em uma estratégia para levar o conhecimento a toda a comunidade. Assim, posteriormente, uma cartilha educativa sobre a importância do saneamento básico, bem como sobre a importância de um tratamento de esgoto, suas vantagens, desvantagens e comparativo econômico com outros modelos de tratamento de esgoto foi elaborada, para que órgãos públicos possam trabalhar com a população de forma a alcançar uma conscientização sobre a importância do assunto para melhorar a vida e a saúde das pessoas
Determination of Affecting Factors on Profitability of Banking Sector: An Examination upon the Turkish Banking Sector for the Period of 2006-2018
Authors: KARTAL Mustafa Tevfik
Published: May 2021

Although net profit of Turkish Banking Sector (TBS) has reached TL 54.1 billion in 2018, the profitability of TBS has been decreasing. Return on assets of TBS has decreased from 2.3% in 2006 to 1.4% in 2018. Similarly, return of equity of TBS has decreased from 18.8% in 2006 to 10.50% in 2018. This figures verify the decreasing trend in profitability. This trend presents risks for limiting of providing credits of banks. Therefore, the level of profitability of TBS has importance. Affecting factors on profitability should be detected first in order to keep profitability stable. In this context, Multivariate Adaptive Regression Splines (MARS) method, 11 explanatory variables, and quarterly data are used between 2006 and 2018. It is determined that net profits, credits, capital, nonperforming loans (NPL)/total credits, total assets, and USD/TL foreign exchange rate (FER) affect the profitability of banking sector in Turkey. Necessary measures should be taken by regulatory authorities to keep net profit stable and increase the profitability of the sector from the current level. Hence, banks could have the opportunity to provide much more credits for financing and supporting economic growth.
Collecting duct PGE2 responses reduce water loss with empagliflozin in mice with type 2 diabetes mellitus

Published: May 2021

Introduction: Sodium-glucose cotransporter 2 inhibitors such as empagliflozin (EMPA) protect against diabetic kidney disease. Prostaglandin E2 (PGE2) the main renal product of cyclooxygenase-2, inhibits vasopressin (AVP)-water reabsorption in the collecting duct (CD). The novelty of this study is that for the first time, we examined if EMPA affects the renal PGE2/EP receptor system and determined if CD responses to EMPA prevent water loss. Methods: Four groups of adult male mice were studied after 6 weeks of treatment: control (db/m), db/m+EMPA (10 mg/kg/day in chow), type 2 diabetic diabetic/dyslipidemia (db/db), and db/db+EMPA. Tubules were microdissected for quantitative polymerase chain reaction (qPCR) and CD water transport was measured in response to AVP, with or without PGE2. Results: Hyperglycemia and albuminuria were attenuated by EMPA. Renal mRNA expression for COX, PGE synthase, PGE2 (EP) receptor subtypes, CD AVP V2 receptors and aquaporin-2 was elevated in db/db mice, but unchanged by EMPA. Urine PGE2 levels increased in db/db but were unchanged by EMPA. AVP-water reabsorption was comparable in db/m and db/m+EMPA, and equally attenuated to 50% by PGE2. In db/db mice, AVP-water reabsorption was reduced by 50% compared to non-diabetic mice, and this reduction was unaffected by EMPA. In db/db mice, AVP-stimulated water transport was more significantly attenuated with PGE2 (62%), compared to non-diabetic mice, but this attenuation was reduced in response to EMPA, to 28%. Conclusion: In summary, expression of renal PGE2/EP receptors is increased in db/db mice, and this expression is unaffected by EMPA. However, in diabetic CD, PGE2 caused a greater attenuation in AVP-stimulated water reabsorption, and this attenuation is reduced by EMPA. This suggests that EMPA attenuates diabetes-induced excess CD water loss.

Published: May 2021

This research focuses on calculating the force distribution on the wings of the LSU 05-NG aircraft by several numerical methods. Analysis of the force distribution on the wing is important because the wing has a very important role in producing sufficient lift for the aircraft. The numerical methods used to calculate the lift force distribution on the wings are Computational Flow Dynamics (CFD), Lifting Line Theory, Vortex Lattice Method and 3D Panel Method. The numerical methods used will be compared with each other to determine the accuracy and time required to calculate wing lift distribution. Because CFDs produce more accurate estimates, CFD is used as the main comparison for the other three numerical methods. Based on calculations performed, 3D Panel Method has an accuracy that is close to CFD with a shorter time. 3D Panel Method requires 400 while CFD 1210 seconds with results that are not much different. While LLT and VLM have poor accuracy, however, shorter time is needed. Therefore to analyze the distribution of lift force on the wing it is enough to use the 3D Panel Method due to accurate results and shorter computing time.

This study aimed to use chemometrics as a tool to allow for near-infrared (NIR) spectroscopy to detect adulteration in Peruvian maca powder. To adulterate the samples, pure maca powder was mixed with rice flour and rice bran, which are the most employed adulterants, using proportions of 25%, 50%, and 75% of each. After adulteration, the mixtures were submitted to NIR spectroscopy. The spectral data were used to build discriminant models through Partial Least Squares Discriminant Analysis (PLS-DA), and each model was evaluated through permutation tests to check for reliability. It was observed that all samples were discriminated against the pure ones, providing unitary sensitivities and specificities. All the models built were tested by the pairwise Wilcoxon signed-rank test, pairwise signed-rank test, and a randomization t-test, and the results indicated that the permuted and un-permuted models were not similar. The results indicated that NIR spectroscopy can be used to discriminate between pure maca powder samples and maca powder adulterated with different levels of rice flour and rice bran, achieving unitary sensitivity and specificity in the PLS-DA models.

Published: May 2021

Adolescents 18-21 years of age today have problems related to

movement that result in changes to resistance training. Exercise

resistance is expressed in VO2max. Body mass index and gender

are factors that influence VO2max. The purpose of this study is

to analyze the relationship between body mass index and sex

on VO2Max and to analyze how closely the relationship is. The

type of this study is an observational study with a purposive

sampling technique with a point time approach design with a

total of 183 samples with criteria for healthy samples aged 18-

21 years. The independent variable in this study was exercise

endurance (VO2max), and the dependent variable was body

mass index and gender. The data is processed using software for

data analysis. From the data normality test using Kolmogorov

Smirnov for Body Mass Index data with a value of 0.001, sex data

with a value of 0.000, VO2Max data with a value of 0.000 which

indicates abnormal data. Test Data analysis using the Spearman

rank test resulted in the value of gender and VO2max 0.001 with

r value of 0.203 and body mass index value and VO2max -0.015

with r value of 0.766.There is a correlation between body mass

index and sex on VO2Max.

Published: May 2021

Desde la década del 90 en Chile, las intervenciones en Psicología Comunitaria se han desarrollado principalmente dentro del marco teórico, material y simbólico de las políticas sociales (Alfaro, 2012), esta relación se ha caracterizado por una tensión entre los modelos de políticas públicas neoliberal y las dimensiones ético-políticas de la Psicología Comunitaria. En esta investigación se analiza el contenido de los relatos que construyen profesionales que trabajan en programas de políticas sociales en Chile, sobre las tensiones que se producen entre su quehacer, las políticas sociales y los principios de la Psicología Comunitaria. Se entrevistó a diez psicólogos-as comunitarias-os, que tienen entre 2 a 26 años de experiencia trabajando en instituciones que ejecutan políticas sociales. Se reporta que la tensión en el quehacer profesional en la política pública, se expresa en el grado de autonomía que otorgan los espacios de trabajo, la disputa profesional de su quehacer en la política pública y las consecuencias personales producto de las tensiones profesionales.

Este estudio se interesa por conocer acerca de la Salud Mental en contextos de pobreza en el sureste de México desde una perspectiva psicológica. A través de la aplicación del Autocuestionario SRQ-20 a 116 hombres y 144 mujeres, se encontró que las personas que viven en contextos de pobreza son propensas a desarrollar síntomas negativos en salud mental, en donde condiciones como ser mujer, soltera, de mayor edad y con bajos ingresos puede aumentar las probabilidades. Se evidencia la importancia de trabajar con la promoción de herramientas de salud mental desde un enfoque de género, para lograr abordajes más integrales que permitan a las personas desarrollar su potencial, manejar situaciones difíciles y contribuir a su propio fortalecimiento personal y comunitario.

Hacia la transformación de la cultura organizacional de una agencia pública: Un modelo híbrido de intervención

Uno de los niveles de intervención de la Psicología Comunitaria (PC) es el nivel organizacional. La intervención descrita es sintónica con los valores y principios de la PC. Los objetivos del proyecto son: aquilatar (assess) los elementos de la cultura organizacional de una dependencia gubernamental en Puerto Rico que constituyen fortalezas y debilidades para el logro de su misión y desarrollar acciones colectivas específicas para motivar y potenciar las capacidades de todos los sectores de la organización para que se involucren en procesos de cambio que aumenten la eficiencia y la efectividad de la agencia, así como la satisfacción individual y colectiva de empleados/as a todos los niveles. El proyecto fue desarrollado en dos fases: una de investigación y otra de intervención. Todos los sectores de la organización participaron en el diseño y ofrecieron sugerencias sobre su alcance e implantación. La fase de intervención sigue un Modelo de Competencias que permite describir el conocimiento, las destrezas y el comportamiento necesario para el desempeño efectivo en una organización. Desarrollamos cinco módulos de capacitación y se administraron pre y post pruebas antes y después de la implantación de los módulos de capacitación. La intervención permitió confirmar la posibilidad de cambio organizacional con implicaciones para el cambio individual.
SURVIVAL ANALYSIS OF UNDER-FIVE CHILDREN WITH SEVERE ACUTE MALNUTRITION IN WOLDIA HOSPITAL: RETROSPECTIVE COHORT STUDY
Authors: Asfaw Aragaw
Published: May 2021

Abstract

Background: Globally, 52 million children of age under five years were affected by acute malnutrition from which 17 million were severely wasted. In Ethiopia every month over 25,000 children with severe acute malnutrition are admitted to hospitals, if not identified early and treated properly, these children could die. Therefore this study aimed to assess the determinants of time to death of under-five children with SAM admitted to inpatient therapeutic feeding center in Woldia General Hospital.

 

Methods: A retrospective cohort study was conducted. The study population were children with severe acute malnutrition aged from 0 to 59 months who have been admitted to woldia general hospital from September 2017 to August 2019.The sample was 150 that fulfils the inclusion criteria were included. Non parametric survival analysis was used to estimate survival time to death and Cox PH model was carried out to determine independent predictors.

 

Results: The accounted proportion of death of under-five children in the study period was 10%. And the estimated mean survival time of the patient was 4.48 weeks. Both estimates was almost on the recommended Sphere standard which should < 10% and <4 weeks respectively. In the estimated model HR for age groups (24-35 months) is 0.000 with 95% CI [0.000-4.591], wasting  is 0.010 with 95% CI [0.000-0.065], referred from is 0.000 with 95% CI [0.000-0.061], cough 133.04 with 95% CI [3.596-4922.83], HIV is 1209.61 with 95% CI [1.137-1286998.42], Iv antibiotic treatment is 0.000 with 95% CI [0.000-0.037] and amoxicillin is 0.001 with 95% CI [0.000-0.736] were significant predictors for time to death of under-five children with SAM.

 

Conclusions: From the fitted model, age of the children, admission criteria, children referred from,cough, HIV, IV antibiotic treatment and Amoxicillin are the covariates that have significant effect on time to death of under five children by SAM at 5% level of significance. Early identifying cases and giving special attention for children with co morbidities such as HIV and cough is vital for decrease child mortality Ethiopia.

Penelitian ini menggunakan menggunakan Rancangan Acak Lengkap yaitu perendaman daging dengan konsentrasi asap cair yang berbeda. Penggunaan asap cair tempurung kelapa mempunyai 3 taraf konsentrasi pengasapan yaitu P1=3%,  P2=6%, dan  P3=9%. Kebutuhan untuk perendaman daging dengan menggunakan asap cair adalah 15 sampel. Variabel yang diukur adalah kadar fenol, kadar protein, kadar benzo (a) pirene, kadar benzo (a) antracena, dan organoleptik meliputi warna, rasa, tekstur dan kesukaan. Pengujian parameter terlebih dahulu di uji normalitasnya dengan menggunakan uji Shapiro-Wilk. Apabila sebaran datanya normal dianalisis dengan ANOVA pada taraf 5%, apabila terdapat pengaruh dilanjutkan dengan uji Wilayah Ganda Duncan. Kadar benzo (a) pirene dan kadar benzo (a) antarcena di uji secara deskriptif dan pengujian  sifat organoleptik (warna, rasa, tekstur dan tingkat kesukaan) menggunakan uji Non Parametrik Kruskal – Walis dan dilanjutkan, uji beda nyata Man Whitney. Hasil penelitian ini menunjukkan bahwa konsentrasi asap cair berbeda dapat memberikan pengaruh yang nyata (P<0,05) terhadap kadar protein, kadar fenol dan organoleptik. Konsentrasi asap cair tertinggi dapat meningkatkan kadar fenol, organoleptic  tetapi  dapat menurunkan kadar protein. Sedangkan kadar benzo (a) pirene  pada semua perlakuan adalah <0,51mg/kg dan kadar benzo (a) antracena pada semua perlakuan adalah <9,08 dan secara kesehatan pemanfaatan asap cair sampai pada 9% masih aman untuk dikonsumsi.
