Authors: Yılmaz Aydın Duygu , Gürü Metin , Sözen Adnan
Published: July 2022

In this paper, the effect of using CaMg(CO3)2/Ethylene Glycol-water (50:50%) as a working fluid on the thermal performance of thermosyphon heat pipe was experimentally studied. Nanofluid was prepared by two-step method using 2% concentration of CaMg(CO3)2 nanoparticle and 0.05% surfactant (Sodium dodecylbenzene sulfonate). For the experimental set-up, a straight copper pipe of one-meter length was used. The inner diameter of the pipe is 13 mm, and the outer diameter is 15 mm. Experiments were conducted at three different cooling water mass flow rates (5, 7.5, and 10 g/s) and different heating powers (200, 300, 400 W) to test heat pipe performance. It was observed that the CaMg(CO3)2 nanofluid reduced the average wall temperature of the heat pipe according to the base fluid. Furthermore, the efficiency and thermal resistance of the heat pipe were investigated separately for EG/water and CaMg(CO3)2 nanofluid. The maximum heat transfer enhancement was obtained as 9.55% under 400 W heating power and 10 g/s cooling water mass flow rate conditions and the maximum improvement in thermal resistance was observed as 21% at 200 W and 10 g/s cooling mass flow rate. Viscosity and specific heat of base fluid and CaMg(CO3)2 nanofluid were also determined and compared to each other.

Mecanismos protectores de la insensibilidad a hormona de crecimiento (síndrome de Laron) contra cáncer y diabetes mellitus
Authors: Moya Pérez Sidney Selena , Medina Medina Doris Raquel
Published: July 2022

Introducción: El eje Hormona liberadora de hormona de crecimiento- hormona del crecimiento- factor de crecimiento insulínico tipo 1 (GHRH-GH-IGF1) demuestra un nivel extraordinario de complejidad biológica. Cuando existe un defecto molecular en el receptor de la hormona de crecimiento, se desencadena una incapacidad para sintetizar el factor de crecimiento IGF-1 en el hígado, es lo que conocemos como el síndrome de insensibilidad a la hormona de crecimiento (GHID). Dentro de este cuadro está el conocido síndrome de Laron, una enfermedad de herencia autosómica recesiva caracterizada por una resistencia primaria a la GH, en Ecuador existe una gran población con este síndrome y en ella se han estudiado varios mecanismos de la insensibilidad a GH así como los efectos metabólicos y celulares de la deficiencia de IGF-1. Presentamos una revisión sistemática de la literatura existente, recopilando información de las bases de datos de Medline, Intra Med, PubMed, The Cochrane, SciELO y otras revistas con evidencia científica de calidad, que analiza la evidencia encontrada en los últimos años que sugieren la existencia de una correlación entre la GHID y el bajo riesgo de padecer Diabetes Mellitus y todos los tipos de cáncer. La insensibilidad primaria a la GH que poseen los pacientes con SL representaría así, una condición favorable en relación con el riesgo de padecer diabetes mellitus y cáncer. Entre los mecanismos protectores sugeridos de la GHID están un incremento de la sensibilidad a la insulina y la disminución de IGF-1 que lleva a una menor progresión de células hacia el cáncer.

Background: Although blood transfusions can be lifesaving but it is not without risk. It is a necessity to have knowledge about the red cell antigen phenotype frequencies in a population to provide antigen-negative compatible blood to patients with multiple alloantibodies. This is the first study on extended phenotype of blood group systems in blood donors at AFIP, Dhaka.
Aim: Present study is aimed to determine the antigen frequencies of “O” blood group phenotype among donors at AFIP, Dhaka.
Methods: An observational study was carried out at AFIP, Dhaka from July 2019 to December 2019. A total of 40 “O” blood group donors from blood bank of AFIP were typed for D, C, c, E, e, K, k, M, N and S antigens either by adding antisera to 3-5% of donor RBCs suspension or by using Indirect Antiglobulin Test (IAT) according to manufacturer’s instruction. Coomb’s control cells, positive and negative control cells were used as quality control. Antigens and phenotype frequencies were expressed as percentages.
Results: Forty (40) blood donors belonging to “O” blood group were included for extended phenotyping. D antigen was found in 100% donors, followed by e [42.5%], C [38.13%], c [11.88%], and E [7.5%] with DCe/DCe (R1R1, 55%) as the most common phenotype. k was found to be positive in 72% of donors. In the MNS system, 57.5% donors were typed as M+N+, 32.5% as M+N-, and 10% as M-N+. S-s+ was found amongst donors with 52.5% as the commonest phenotype.
Conclusion: This study was conducted to provide information about the antigen frequency of a common blood group “O” in local donors to provide antigen negative compatible blood units to multi transfused alloimmunized patients. D antigen was found in 100% donors with DCe/DCe (R1R1, 55%) as the most common phenotype.

Published: July 2022

Autism spectrum disorder has precipitously mounted globally since the early 1990s. The Autism rise in amount has flashed fears of an autism epidemic. Autism spectrum disorder (ASD) is a complex developing condition. Although ASD can be an enduring disorder, early diagnosis and treatments can improve a person’s symptoms and daily functioning. Study shows that 1 in 54 children has been diagnosed with autism spectrum disorder (ASD); it is a spectrum form, which means that all persons with autism represent certain difficulties. Since there is no specific diagnostic test, experts are still hunting for accurately what causes autism. The core features must be present in early development, like obstacles in social communication and interactions and restricted interests or repetitive behaviors. Multi F factors influence autism spectrum disorder, like gut-brain health, Microbiome dysfunction in the gastrointestinal tract, autoimmune disease, etc. Many research study findings are that probiotics may help diminish the inflammatory condition and modulate the Gastrointestinal problem and behavioral abnormality in ASD. Exclusive breastfeeding has the lowest risk of autism spectrum disorder; it decreases the 76 % chances of ASD. A proper supplement like folic acid during the first-trimester act as protective against ASD. Material and method: Relevant articles and literature were retrieved from different journals and web pages to find out the Autism details and how it related to various factors.

Published: July 2022

The objective of this study was to evaluate the antimicrobial potential of essential oil (EO) from L. origanoides against Gram-negative bacteria with multidrug resistance (MDR) phenotype and to correlate the results obtained with the genetic profile of these microorganisms. The oil was extracted from the leaves of this plant by steam dragging and condensation with Clevenger equipment, the chemical components were identified and quantified by gas chromatography coupled with mass spectrometry and gas chromatography coupled with the flame ionization detector. Twenty clinical isolates and one standard strain of each species were analyzed: E. coli, K. pneumoniae and P. aeruginosa (n=63). The antibacterial potential was evaluated by broth microdilution tests. Thymol is the prevalent component (87.37%). The EO at a concentration of 312 μg/mL was effective in inhibiting 52% of E. coli strains and about 38% of K. pneumoniae. On the other hand, for P. aeruginosa a concentration of 2,500 μg/mL was needed to obtain growth inhibition of approximately 38% of the strains. Among the resistance genes detected, the highest prevalence was blaCTX-M 1/2, however, even with the presence of these genes, an antimicrobial action of this EO was observed. Therefore, the results of this study suggest that the EO of L. origanoides presented an efficient antibacterial action with potential use in the fight against infections by MDR microorganisms.

The School Food Council (CAE) is a deliberative, supervisory, and advisory body of the Brazilian National School Feeding Program (PNAE). This study was aimed at proposing a model to strengthen CAE performance. The research was carried out with CAE members of a municipality in the central region of Rio Grande do Sul State, south Brazil. The study consisted of the following phases: diagnosis to make a profile of the Council members; participation in the meetings and reading of the minutes; interventions (training, interview with school principals, elaboration of the assessment instrument, school visits, and development and validation of software); and evaluation of the interventions. Despite the low participation of the counsellors, strengthening of CAE in this municipality was achieved; all actions carried out along the work were useful to help and guide the members to have a good, correct and effective performance within the Council and during school visits and assessments. Based on the current study, further work addressing this issue in municipalities of different sizes is suggested so that more specific comparison and analysis of CAE performance in Brazil are possible.

Published: July 2022

Objective: This prospective and cross-sectional study investigated the occurrence of obstructive sleep apnea (OSA) and related symptoms in medical students. Method: Sociodemographic and anthropometric data were collected. The survey included the Epworth sleepiness scale, Berlin questionnaire, STOP-Bang, and NoSAS. Participants underwent overnight digital monitoring of respiratory events (≥ 3% drop in SpO2) using a high-resolution oximeter. Those with high risk for OSA in the Berlin questionnaire or an oxygen desaturation index ≥ 5 to < 15 events/hour, were examined through type 3 polysomnography. Results: The evaluated sample comprised 64 students, aged 22.3±2.3 years, and 38 (59.4%) males. A high risk for OSA frequency was detected in 10.9% of the sample through the Berlin questionnaire, and in 4.7% through STOP-Bang and NoSAS. A mild form of this disorder was diagnosed in 4.7% of the sample through type 4 polysomnography, and in 6.2% using type 3 polysomnography. Excessive daytime sleepiness and being overweight were associated with the occurrence of mild obstructive sleep apnea (p ≤0.05). Males presented higher body mass index values, neck circumference, oxygen desaturation index events/hour, and continuous values in the Berlin questionnaire, STOP-Bang, and NoSAS, than females (p ≤0.05). Conclusion: Despite a low occurrence of the assessed sleep-disordered breathing among medical students, male gender, overweight and sleepiness consisted of factors associated with obstructive sleep apnea, indicating that medical students with this profile should be early and systematically screened for this condition.

This study aims to determine the relationship between mindfulness and self-acceptance among members of the Jogja Mindfulness Weekend community. The sampling method used was a saturated sampling technique involving 32 members of the Jogja Mindfulness Weekend community aged 20-50 years. Mindfulness data retrieval using the Five Facet Mindfulness Questionnaire (FFMQ) scale from Baer et al (2006) theory and has a Cronbach's alpha value = 0.896 while for self-acceptance using the Self-Acceptance Questionnaire (SAQ) scale from Sheerer theory (Sulistya, 2005) and has cronbach's alpha value = 0.942. Data retrieval via google form distributed to each participant with data analysis techniques using the Pearson product moment correlation test with the help of the SPSS ver 24 application. From the results of the study, the value of r = 0,767 (p<0,05) which means that there is a positive and significant relationship between mindfulness and self-acceptance. Thus Hypothesis (H1) is accepted where it shows that there is a positive and significant relationship between mindfulness and self-acceptance. This means, the higher the level of mindfulness, the higher the level of self-acceptance among members of the Jogja Mindfulness Weekend community. Vice versa, the lower the level of mindfulness, the lower the level of self-acceptance for members of the Jogja Mindfulness Weekend community.
THE END OF THE AMERICAN CENTURY? A SHORT HISTORY OF US FOREIGN POLICY FROM WORLD WAR II TO THE PRESENT
Authors: D. SCHULTZ
Published: July 2022

In 1941 H. Luce famously declared the arrival of the American century where the US would emerge as the dominant superpower in the world. After the end of World War II and then again in 1991 after the collapse of the Soviet Union, it looked in many ways like H. Luce’s prediction was correct. However the world today looks very different compared to 1945 or 1991. This article looks at the way the world and US foreign policy have evolved, contending that the foreign policy options for the United States are very different now and in the future from what they once were. Both the D. Trump and now J. Biden foreign policies are the result of these changes, and the article looks at some of the challenges facing the US going forward.

La transformación digital en el Perú se intensificó en el año 2020 para posibilitar el progreso social, el crecimiento económico y una mayor confianza en el gobierno. Utilizar tecnologías digitales ya no es una opción, su aprovechamiento permite mejores condiciones de vida al ciudadano y no hacerlo incrementa las desigualdades sociales. La metodología adoptada en este artículo corresponde a una revisión bibliográfica de la literatura científica y técnica sobre transformación digital en la administración pública, a través de bases de datos de revistas arbitradas (Scopus, Scielo, Proquest, Redalyc y Google académico) correspondientes a los últimos cinco años. La conclusión a que se arriba es que la digitalización debe considerarse como una oportunidad para mejorar la gobernanza, a través de la restructuración de los servicios públicos, utilizando intensivamente las tecnologías digitales con la finalidad de incrementar su eficacia y eficiencia para lograr el bienestar digital de los ciudadanos y ahorros sustanciales. La transformación digital, a su vez, demanda previamente la reducción de las brechas en los ecosistemas digitales, tanto en infraestructura de comunicaciones de alta calidad como en su masificación. Debido a las brechas existentes, la ciudadanía digital en el Perú está en proceso de construcción.

Sports in Healing International Relations
Authors: Alarachi Ahmad
Published: July 2022

What may be considered the “traditional” type of diplomacy is that which involves state representatives from (conflicting) nations meeting one another and discussing potential solutions. However, other types of diplomacy have emerged in recent history, one being sports diplomacy--the use of sports in fostering international relations. Though sports appear to have merit in healing international relations, their potential may be largely based on speculation; there are few concrete examples of sports being successfully used for this purpose. Additionally, sports can even lead nations in the opposite direction of progress, exacerbating tensions between them. This conclusion is arrived at through the exploration of various examples of sports diplomacy, within situations ranging from the Cold War to the Israeli-Palestinian Conflict.

Livestock offers substantial opportunities for food security and sustainable development with appropriate adaptation to climate change. Nowadays, climate change is among the critical problems facing less privileged rural people directly depending on livestock to survive. This paper aimed to analyse the existing literature and identify knowledge gaps about climate change impacts and response strategies in rural livestock production of South Africa. The study utilized a systematic literature review with key search terms such as “climate change” (weather, variability), “livestock” (monogastric*ruminants), “impact” (heat stress; feeds; pasture; production; reproduction; health; vector-diseases), and “adaptation” (strategies; vulnerability; risks; resilience). The search was run through scientific databases such as Google scholar, Science direct, Cab direct, Sabinet and Sematic scholar, targeting titles, abstracts and keywords. From the 62 suitable peer-reviewed publications examined in the current paper, five limitations were discovered, namely: (1) limited contextual studies of South Africa’s rural livestock farming communities; (2) a silo approach to investigations on impacts and adaptation in rural livestock production; (3) drawbacks on mixed crop-livestock systems as an effective response to climate change; (4) limited studies on monogastric livestock in rural communities; and (5) geographic underrepresentation of research progress in different provinces within the country. The study recommended improving geographic coverage of literature and inclusion of non-ruminants exposed to different climatic shocks. It is further advised that to gain effective responses to climate change impacts, mitigation strategies should be context-specific and holistic to improve livestock production in rural farming communities.

Osteoarthritis (OA) is a common type of arthritis characterized by degeneration of the articular cartilage and joint dysfunction. Various pharmacological and non-pharmacological techniques have been used to manage these diseases. Due to the diverse therapeutic properties of marine collagen, it has received considerable attention in its pharmacological application. Thus, the purpose of this study was to compare the efficacy of jellyfish collagen, collagen peptide, other sources of marine collagen, and glycine in treating OA. In the OA rat model, an anterior cruciate ligament transection combined with medial meniscectomy surgery (ACLT + MMx) was used to induce osteoarthritis in rats. Two weeks before surgery, male Sprague–Dawley rats were fed a chow-fat diet. After 6 weeks of treatment with collagen, collagen peptide, and glycine, the results show that they could inhibit the production of proinflammatory cytokines and their derivatives, such as COX-2, MMP-13, and CTX-II levels; therefore, it can attenuate cartilage degradation. Moreover, collagen peptides can promote the synthesis of collagen type II in cartilage. These results demonstrate that collagen and glycine have been shown to have protective properties against OA cartilage degradation. In contrast, collagen peptides have been shown to show cartilage regeneration but less protective properties. Jellyfish collagen peptide at a dose of 5 mg/kg b. w. has the most significant potential for treating OA because it protects and regenerates cartilage in the knee.
Pedestrian Wind Comfort Assessment Using Computational Fluid Dynamics Simulations With Varying Number of Wind Directions

Published: July 2022

The construction of a building inevitably changes the microclimate in its vicinity. Many city authorities request comprehensive wind studies before granting a building permit, which can be obtained through Computational Fluid Dynamics (CFD) simulations. Investigating the wind conditions for 12 wind directions has previously been considered sufficient in most literature and the industry. However, the effect of changing the number of simulated wind directions is still not well understood. This article investigates the influence of the number of simulated wind directions on pedestrian wind comfort maps. A neighborhood in Niigata city, Japan, was chosen as a case study. Simulations are performed in OpenFOAM using a Reynolds-averaged Navier-Stokes model and the realizable k-ϵ turbulence model. The inlet profiles form a homogeneous atmospheric boundary layer with neutral stratified conditions and a logarithmic velocity profile. The pedestrian wind comfort maps are converging toward a final map as more wind directions are included. The area of the maps classified with the same comfort as using 64 wind directions is 79% using 4 wind directions, 92% using 8 wind directions, 96% using 16 wind directions, and 99% using 32 wind directions. A greater understanding of the influence of the number of simulated wind directions included may enable more efficient pedestrian wind comfort studies that recognize the associated uncertainties.

Introduction

The gut microbiota influences and interacts with the host metabolism through effects on nutrient metabolism and digestion. Duodenal Mucosal Resurfacing (DMR) is a novel endoscopic procedure involving duodenal mucosal ablation by the use of hydrothermal energy. DMR, when combined with a glucagon-like peptide-1 receptor agonist (GLP-1RA), resulted in discontinuation of exogenous insulin treatment in 69% of patients with insulin dependent type 2 diabetes mellitus (T2DM) in the INSPIRE study. These patients also experienced improved glycaemic control and metabolic health. We thus investigated if these clinical effects were associated with a change in gut microbiota alpha and beta diversity.

Methods

Faecal samples from the 16 patients were obtained for Illumina shotgun sequencing at baseline and 3 months after DMR. We assessed alpha and beta diversity of the gut microbiota in these samples and analysed its correlations with changes in HbA1c, body weight, and liver MRI proton density fat fraction (PDFF).

Results

HbA1c correlated negatively with alpha diversity (p=0.011, rho: -0.62) whereas changes in PDFF correlated significantly with beta diversity (p=0.036, rho: 0.55) 3 months after initiation of the combined intervention. These correlations with metabolic parameters were observed despite finding no change in gut microbiota diversity at 3 months post DMR.

Discussion

The correlation between gut microbiota richness (alpha diversity) and HbA1c as well as the change in PDFF and changed microbiota composition (beta diversity) suggests that changed gut microbiota diversity is associated with metabolic improvements after DMR in combination with glucagon-like-peptide-1 receptor agonist in type 2 diabetes. Larger controlled studies are however needed to find causal links between DMR with GLP-1RA, the gut microbiota, and improvements in metabolic health.
