While fatty acids found in human milk account for half of the energy consumed by exclusively breastfed infants, fatty acids such as monounsaturated fatty acids (MUFA) and long chain polyunsaturated fatty acids (LC-PUFA) plays critical roles in infant growth. Fatty acids components in human milk are vary widely accordance to the maternal diet during lactation but has not been sufficiently studied. The objective of this paper was to determine the correlation between maternal macronutrient intake with human milk’s fatty acids composition among exclusively breastfeeding mothers. A total of N=36 lactating mothers were recruited based on convenience sampling basis from Dengkil, Selangor and Kuantan, Pahang. A 24-hour dietary recall (24HR) was used to capture mother’s dietary intake in the past 24 hours. The human milk sample was collected in the next day morning after the diet recall and stored before proceeded to another fatty acids extraction and transesterification process namely Blight and Dyer method. The composition of fatty acids methyl esters was analyzed and quantified by a gas chromatography (Agilent 7890A), equipped with a flame ionization detector (FID) and Agilent Chromatography Workstation software. As overall, the most abundance fatty acids found was SFA ranged (81.90 to 97.7 %) followed with MUFA (2.3 to 18.1%), but PUFA was below detection limit (BDL). Result also indicated that palmitic, stearic, and oleic acids were the three major types of fatty acids determined from human milk. Correlational study also determined that, there was no significant correlation between the human milk’s SFA and MUFA with the same dietary intake and another macronutrient like carbohydrate and protein. Even though there was no significant correlation determined for the most composition, various pattern of correlation was found in the study. Human milk’s SFA only had a positive correlation with dietary carbohydrate but negative with the rest. Different pattern also showed for human milk’s MUFA which only negatively correlate with carbohydrate and fats while positive for the rest. Thus, overall, this fat composition is known to have higher variation in terms of concentration of its components compared to another macronutrient even within the same population. Aside from geographical considerations, maternal nationality and age have a substantial impact on the fatty acid composition of human milk.

Published: February 2024

Two coupled circuits are extensively used in radio electronics and communication. The problem of stability analysis of state variables describing system of two coupled circuits is very critical as unstable circuit causes damage to electrical systems. Analysis of stability and boundedness behavior of the state variables characterizing system of two coupled circuits is carried out using the Lyapunov's second method. We provide in simple form, less restrictive conditions that are implementable at the development stage and which ensure the stability and boundedness of the state variables describing system considered. For illustration, the behaviours of the system of two coupled circuits with response and its bounded output are shown.
Muscle strength and non-alcoholic fatty liver disease/metabolic-associated fatty liver disease
Authors: Hao Xuan-Yu , Zhang Kai , Huang Xing-Yong , Yang Fei , Sun Si-Yu
Published: February 2024

This editorial comments on an article published in a recent issue of World Journal of Gastroenterology, entitled “Association of low muscle strength with metabolic dysfunction-associated fatty liver disease: A nationwide study”. We focused on the association between muscle strength and the incidence of non-alcoholic fatty liver disease (NAFLD) and metabolic-associated fatty liver disease (MAFLD), as well as the mechanisms underlying the correlation and related clinical applications. NAFLD, which is now redefined as MAFLD, is one of the most common chronic liver diseases globally with an increasing prevalence and is characterized by malnutrition, which may contribute to decreased muscle strength. Reduction of muscle strength reportedly has a pathogenesis similar to that of NAFLD/ MAFLD, including insulin resistance, inflammation, sedentary behavior, as well as insufficient vitamin D. Multiple studies have focused on the relationship between sarcopenia or muscle strength and NAFLD. However, studies investigating the relationship between muscle strength and MAFLD are limited. Owing to the shortage of specific medications for NAFLD/MAFLD treatment, early detection is essential. Furthermore, the relationship between muscle strength and NAFLD/MAFLD suggests that improvements in muscle strength may have an impact on disease prevention and may provide novel insights into treatments including dietary therapy, as well as tailored physical activity.

Published: February 2024

Metabolic dysfunction-associated steatotic liver disease (MASLD) affects approximately 25% of the world's population and has become a leading cause of chronic liver disease. In recent years, an increasing amount of data suggests that MASLD is associated with aging. As the population ages, age-related MASLD will become a major global health problem. Targeting an aging will become a new approach to the treatment of MASLD. This paper reviews the current studies on the role of aging-related factors and therapeutic targets in MASLD, including: Oxidative stress, autophagy, mitochondrial homeostasis, bile acid metabolism homeostasis, and dysbiosis. The aim is to identify effective therapeutic targets for age-related MASLD and its progression.
Metformin and pancreatic neuroendocrine tumors: A systematic review and meta-analysis
Authors: Cigrovski Berkovic Maja , Coppola Alessandro , Sesa Vibor , Mrzljak Anna , Lai Quirino
Published: February 2024

BACKGROUND

Most patients with advanced pancreatic neuroendocrine tumors (pNETs) die due to tumor progression. Therefore, identifying new therapies with low toxicity and good tolerability to use concomitantly with the established pNET treatment is relevant. In this perspective, metformin is emerging as a molecule of interest. Retrospective studies have described metformin, a widely used agent for the treatment of patients with type 2 diabetes mellitus (T2DM), to be effective in modulating different tumor-related events, including cancer incidence, recurrence and survival by inhibiting mTOR phosphorylation. This systematic review evaluates the role of T2DM and metformin in the insurgence and post-treatment outcomes in patients with pNET.

AIM

To systematically analyze and summarize evidence related to the diagnostic and prognostic value of T2DM and metformin for predicting the insurgence and post-treatment outcomes of pNET.

METHODS

A systematic review of the published literature was undertaken, focusing on the role of T2DM and metformin in insurgence and prognosis of pNET, measured through outcomes of tumor-free survival (TFS), overall survival and progression-free survival.

RESULTS

A total of 13 studies (5674 patients) were included in this review. Analysis of 809 pNET cases from five retrospective studies (low study heterogeneity with I² = 0%) confirms the correlation between T2DM and insurgence of pNET (OR = 2.13, 95%CI = 1.56-4.55; P < 0.001). The pooled data from 1174 pNET patients showed the correlation between T2DM and post-treatment TFS in pNET patients (hazard ratio = 1.84, 95%CI = 0.78-2.90; P < 0.001). The study heterogeneity was intermediate, with I² = 51%. A few studies limited the possibility of performing pooled analysis in the setting of metformin; therefore, results were heterogeneous, with no statistical relevance to the use of this drug in the diagnosis and prognosis of pNET.

CONCLUSION

T2DM represents a risk factor for the insurgence of pNET and is a significant predictor of poor post-treatment TFS of pNET patients. Unfortunately, a few studies with heterogeneous results limited the possibility of exploring the effect of metformin in the diagnosis and prognosis of pNET.

Authors: Hutagaluh Oskar , Muin Rahmawati
Published: February 2024

This research was motivated by researchers' interest in the figure of Umer Chapra as one of the leading figures in Islamic economics and finance. One of Chapra's deep and critical ideas is about usury or bank interest which he put into a small book entitled "Prohibition of Interest: Does it make sense?". This work was quite "impressive" for Chapra because it was written at the request of many people who wanted to see Chapra's critical review regarding bank interest. This research aims to examine various main ideas that dominantly exist in Chapra's economic thinking in the book "The Prohibition of Interest". This research is a study with a qualitative paradigm and is also included in library research. The primary source for this research was obtained from Chapra's original work, while the secondary source came from the works of other people who studied Chapra's thinking, both from research, book reviews and other articles. There are various interesting views discussed by Chapra on economic problems. However, overall, it is revealed that Chapra's thinking in an economic context basically carries the principles of justice and freedom, as part of the principles of Islamic economics.

Authors: López Rodríguez Víctor Manuel
Published: February 2024

Introducción: Actualmente la actividad médica en relación con la responsabilidad penal ha ido en aumento con una posible demanda relacionada a una mala praxis. La medicina está completamente relacionada con el ámbito legal al tratarse de problemas que pueden involucrar hasta la muerte, lo que la convierte en una de las profesiones más complejas observadas desde esta perspectiva. Objetivo: Conocer los fundamentos legales de la responsabilidad médica tras analizar el marco legal en México. Metodología: Este artículo se realizó mediante una búsqueda bibliográfica en diferentes fuentes de información. Se caracterizó por ser una revisión de la literatura documental a través del método descriptivo. Desarrollo: La responsabilidad médica abarca aspectos administrativos, civiles y penales, cada uno con sus propias características legales. En los casos de daño corporal, se busca la compensación económica de acuerdo con la ley federal del trabajo. En México la comisión nacional de arbitraje médico busca resolver disputas de manera eficiente. En casos judiciales, se busca compensación por daños, considerando factores como responsabilidad y situación financiera. Conclusiones: El ámbito de la resolución médico-legal en la responsabilidad penal en México plantea desafíos significativos que afectan a médicos, pacientes y al sistema legal en su conjunto, por lo que es imperativo promover una formación médica que incluya aspectos éticos y legales, así como resoluciones justas que se impartan mediante el procedimiento legal en cualquier ámbito en el que se aborde la responsabilidad médica.

According to previous studies, it can be seen that education has been facing new challenges to improve the quality of student teaching by achieving a better interpretation of the conceptual part and the experimental part as they are directly related, improving learning in natural science courses that require students to carry out experiments in laboratories to consolidate their knowledge. The problem raised in this research is that the teaching of the theoretical part is more important than the experimental part with respect to the Physics course due to the little time students have in the laboratories, as well as the limited space that does not allow them to freely carry out experiments in laboratories as poor infrastructure, resulting disadvantageous for students by not demonstrating the hypotheses raised from the theory that would allow them to consolidate their knowledge. The aim of this research work is to develop a virtual assistance system for teaching physics experiments to university students with a high level of reality in order to improve the student's experimental practice, taking advantage of a new form of centralised teaching that prioritises the student's time and space through a dynamic interface. The methodology used for this research is based on a client-server model, a TCP/IP data protocol that allows the computer to send and receive data, graphical features of the operating system with the Microsoft Windows platform for interaction with the virtual laboratory without time restriction. According to the tests carried out, it was observed that the virtual assistance system was performed efficiently by detailing the tests of its corresponding function with an efficiency of 95.14%, which is a high value for a virtual laboratory system that allows experimental processes to be carried out. It was concluded that this system presents a dynamic interaction to perform experiments in the virtual physics laboratory with the appropriate materials for better learning.
Evaluating The Use Of Multi-Sided Platforms On The Brand Performance Of Malaysian SME Food Outlets
Authors: Bryan Teoh Phern Chern  , Fauziah Sh. Ahmad
Published: February 2024

The Malaysian food industry has been increasingly using the services of multi-sided platforms (MSPs) to offer online food delivery services, especially in urban cities such as Kuala Lumpur and Penang. Various global research has also found consistent indications that this trend will continue to grow over the next few years. This service involves the active collaboration between MSPs such as GrabFood and Foodpanda, delivery riders, end consumers, and food outlets. While there are many studies that evaluate the MSP business model and consumer behavior in this industry, there are limited studies that focus on the perspective of the food outlets. This study will address this research gap while focusing specifically on Malaysian SME food outlets to see if using MSPs to offer online food delivery services can improve their brand performance, both in terms of financial performance and brand equity. In addition, the study evaluates the effect that a food outlet’s intellectual capital has on the decision to use MSPs. The study also includes perceived environmental turbulence as a moderating variable on the relationship between MSPs and brand performance. The result of the study shows the impact of different intellectual capital assets on business model innovation activity. It also shows that there is no significant moderating impact of environmental turbulence on this industry even though there is evident turbulence. Lastly, the results show that using MSPs does improve the brand performance of Malaysian SME food outlets.

Published: February 2024

The high availability of technology-related jobs is currently not fulfilled by enough supply of technology graduates, specifically the ones coming from science, technology, engineering, and mathematics (STEM) courses. This is related to the low enrolment rate of STEM-based courses at Universities. The notion that STEM subjects are intense and difficult to pass could be the reason of such phenomena. This research experimented different lecture delivery methods comprising of different seating arrangements, inclusion or exclusion of break, group size, and room size to investigate the generated levels of stress among STEM students, so that the method that would induce minimum stress could be discovered. The analysis of the generated heart rates as stress indication concludes that the level of difficulty of STEM subject’s topic is the one that most affected students’ level of stress, while inclusion of break during class is imperious to destress students. Class arrangement with far seating was discovered to be potentially more stressful for certain students indicated by the high level of resting heart rate in one of the experiments. Importantly, it was also found that regardless of lecture delivery method, STEM subjects in general remained challenging that was suggested by the consistently high recorded heart rates, which was also a sign of active learning engagement - besides implying the level of stress. Finally, gender-wise, there is no visible data pattern that could hint that certain gender is more vulnerable to stress when handling STEM subjects.

Published: February 2024

Este artigo discute a transição do financiamento do setor de saneamento, que historicamente foi uma responsabilidade do Estado, para um maior envolvimento do setor privado no Brasil. Isso se deve principalmente à Lei nº 11.445/2007, que estabeleceu a tarifa cobrada diretamente dos usuários dos serviços como base para o investimento no setor de saneamento e é acelerado pela Lei nº 14.026/2020, que tem como objetivo aumentar a participação privada no setor. O artigo apresenta o perfil dos gastos do setor de saneamento, destacando a importância de monitorar essa transição e outras mudanças estruturantes que ocorrem no setor.
Biodiversidade e serviços ecossistêmicos : temas indissociáveis e estratégicos para o desenvolvimento econômico, socialmente inclusivo e ambientalmente sustentável do Brasil
Authors: Roma Júlio César , Viana João Paulo
Published: February 2024

Ao longo dos últimos catorze anos, pesquisadores da Coordenação de Estudos em Sustentabilidade Ambiental do Ipea, em parceria com diversas instituições nacionais, desenvolveram uma série de estudos sobre biodiversidade e serviços ecossistêmicos. As pesquisas abrangeram o esclarecimento de aspectos conceituais, amplas revisões bibliográficas e análise de indicadores e dados originais, principalmente sobre a relação entre biodiversidade, serviços ecossistêmicos, economia e bem-estar humano, com foco no aperfeiçoamento das políticas públicas brasileiras. Os resultados obtidos, alguns dos quais mencionados neste texto, reforçam que a biodiversidade e os serviços ecossistêmicos são um importante componente do capital natural brasileiro, gerador de benefícios econômicos e bem-estar, em escala global. Dessa forma, esses são temas indissociáveis e cada vez mais estratégicos para o desenvolvimento econômico, socialmente inclusivo e ambientalmente sustentável do Brasil. Sua complexidade e a necessidade de monitoramento e aperfeiçoamento constantes das políticas públicas relacionadas, sobretudo ante o desafio adicional das mudanças climáticas – que tendem a agravar os efeitos negativos, já em andamento, da perda de biodiversidade e de serviços ecossistêmicos em nível mundial –, demandam o reforço e a ampliação desses temas na agenda de pesquisas do Ipea, bem como o estabelecimento de novas sinergias, por meio de parcerias institucionais com essa finalidade.

O objetivo deste texto é mostrar evidências acerca das potencialidades de algumas políticas públicas já consolidadas no Estado brasileiro e apresentar a linha de pesquisa em agricultura sustentável e segurança alimentar e nutricional desenvolvida no âmbito da Diretoria de Estudos e Políticas Regionais, Urbanas e Ambientais do Instituto de Pesquisa Econômica Aplicada (Dirur/Ipea). É mostrado um breve histórico das pesquisas desenvolvidas e uma revisão dos seus principais resultados na perspectiva dos Objetivos de Desenvolvimento Sustentável (ODS). Destacam-se principalmente os estudos de avaliação do Programa de Aquisição de Alimentos (PAA) e da Política Nacional de Agroecologia e Produção Orgânica (PNAPO). Os resultados mostram a relevância dessas políticas para a promoção de sistemas agroalimentares saudáveis e sustentáveis e, também, os diversos desafios enfrentados, especialmente a redução dos recursos aplicados e a desestruturação das políticas ocorridas a partir de 2016. Na perspectiva atual de retomada dos investimentos, os estudos realizados nessa linha de pesquisa são importantes, pois mostram um registro do que foi construído anteriormente e trazem sugestões de aprimoramento para que se possa avançar na reconstrução das políticas públicas voltadas ao desenvolvimento sustentável.
A Contribuição da DIRUR/Ipea na avaliação dos fundos constitucionais de financiamento
Authors: Ribeiro Márcio Bruno
Published: February 2024

A partir de uma sistematização dos trabalhos realizados desde a segunda metade dos anos 2000 no âmbito da Diretoria de Estudos e Políticas Regionais, Urbanas e Ambientais do Instituto de Pesquisa Econômica Aplicada (Dirur/Ipea), este ensaio discute a contribuição desses textos no processo de avaliação dos fundos constitucionais de financiamento. A diversidade de trabalhos produzidos no período, publicados nas formas de Textos para Discussão e capítulos de livros, não apenas consolidou a temática como uma das principais linhas de pesquisa da diretoria, como permitiu a obtenção de um amplo diagnóstico, contemplando aspectos relativos à dinâmica da alocação no território, aos efeitos quantitativos em distintas escalas geográficas e à percepção dos agentes sobre a vinculação dos recursos a uma política de desenvolvimento regional. Os resultados obtidos podem ser utilizados como subsídios na busca pelo aumento da eficácia dos empréstimos, o que envolve uma distribuição mais equitativa, bem como maior integração com localidades, setores e tomadores menos favorecidos.
A DIRUR/Ipea e a urgência da redução das desigualdades regionais brasileiras
Authors: Carleial Liana
Published: February 2024

Inicialmente, demarca-se o processo vivenciado coletivamente pelos técnicos da diretoria para construção de um desenho institucional que contemplasse os objetivos da Diretoria de Estudos e Políticas Regionais, Urbanas e Ambientais (Dirur) e os seus próprios interesses de atuação profissional. O lançamento do Boletim Regional, Urbano e Ambiental, em 2008, representou o compromisso com uma produção continuada e relevante, o que este número especial comemorativo retrata por meio dos artigos ora publicados. Em seguida, discute-se a permanência das desigualdades regionais e a demora em cumprir, efetivamente, o art. 3. da Constituição Federal de 1988. O artigo reconhece que, nos últimos anos, o país instalou uma dinâmica econômica puxada pelo agronegócio, com implicações no padrão de divisão inter-regional do trabalho, alterando também sua posição na Divisão Internacional do Trabalho (DIT), ao retomar sua condição de produtor e exportador de produtos primários. Ademais, o país enfrenta a intensificação do processo de desindustrialização, na ausência de políticas industriais consistentes. Este contexto coloca dificuldades, restrições e desafios para a concepção e implementação de um programa de desenvolvimento de longo prazo para o país que priorize a redução das desigualdades regionais e atenda às exigências inadiáveis de preservação do meio ambiente e de enfrentamento ao aquecimento global já em curso.
Dynamical Structures Associated with High-Order and Secondary Resonances in the Spin–Orbit Problem
Authors: Lei Hanlun
Published: February 2024

In our solar system, spin–orbit resonances are common under Sun–planet, planet–satellite, and binary asteroid configurations. In this work, high-order and secondary spin–orbit resonances are investigated by taking numerical and analytical approaches. Poincaré sections as well as two types of dynamical maps are produced, showing that there are complicated structures in the phase space. To understand numerical structures, we adopt the theory of perturbative treatments to formulate resonant Hamiltonian for describing spin–orbit resonances. The results show that there is an excellent agreement between analytical and numerical structures. It is concluded that the main V-shape structure arising in the parameter space

is sculpted by the synchronous primary resonance, those minute structures inside the V-shape region are dominated by secondary resonances and those structures outside the V-shape region are governed by high-order resonances. Finally, the analytical approach is applied to binary asteroid systems (65803) Didymos and (4383) Suruga to reveal their phase-space structures.

Published: February 2024

For the first time, we generate solar coronal parameters (density, magnetic field, radial velocity, and temperature) on a near-real-time basis by deep learning. For this, we apply the Pix2PixCC deep-learning model to three-dimensional (3D) distributions of these parameters: synoptic maps of the photospheric magnetic field as an input and the magnetohydrodynamic algorithm outside a sphere (MAS) results as an output. To generate the 3D structure of the solar coronal parameters from 1 to 30 solar radii, we train and evaluate 152 distinct deep-learning models. For each parameter, we consider the data of 169 Carrington rotations from 2010 June to 2023 February: 132 for training and 37 for testing. The key findings of our study are as follows: First, our deep-learning models successfully reconstruct the 3D distributions of coronal parameters from 1 to 30 solar radii with an average correlation coefficient of 0.98. Second, during the solar active and quiet periods, the AI-generated data exhibits consistency with the target MAS simulation data. Third, our deep-learning models for each parameter took a remarkably short time (about 16 s for each parameter) to generate the results with an NVIDIA Titan XP GPU. As the MAS simulation is a regularization model, we may significantly reduce the simulation time by using our results as an initial configuration to obtain an equilibrium condition. We hope that the generated 3D solar coronal parameters can be used for the near-real-time forecasting of heliospheric propagation of solar eruptions.

High-latitude (∣b∣ > 30°) molecular clouds have virial parameters that exceed 1, but whether these clouds can form stars has not been studied systematically. Using JCMT SCUBA-2 archival data, we surveyed 70 fields that target high-latitude Planck Galactic cold clumps (HLPCs) to find dense cores with density of 105–106 cm−3 and size of <0.1 pc. The sample benefits from both the representativeness of the parent sample and its coverage of the densest clumps at the high column density end (>1 × 1021 cm−2). At an average rms of 15 mJy beam−1, we detected Galactic dense cores in only one field, G6.04+36.77 (L183) while also identifying 12 extragalactic objects and two young stellar objects. Compared to the low-latitude clumps, dense cores are scarce in HLPCs. With synthetic observations, the densities of cores are constrained to be n

≲ 105 cm−3 should they exist in HLPCs. Low-latitude clumps, Taurus clumps, and HLPCs form a sequence where a higher virial parameter corresponds to a lower dense-core detection rate. If HLPCs were affected by the Local Bubble, the scarcity should favor turbulence-inhibited rather than supernova-driven star formation. Studies of the formation mechanism of the L183 molecular cloud are warranted.
