RESUMO

The immediate early gene exhibits activation markers in the nervous system consisting of ARC, EGR-1, and c-Fos and is related to synaptic plasticity, especially in the hippocampus. Immediate early gene expression is affected by physical exercise, which induces direct ARC, EGR-1, and c-Fos expression. Objective: To assess the impact of exercise, we conducted a literature study to determine the expression levels of immediate early genes (ARC, c-Fos, and EGR-1). Methods: The databases accessed for online literature included PubMed-Medline, Scopus, and ScienceDirect. The original English articles were selected using the following keywords in the title: (Exercise OR physical activity) AND (c-Fos) AND (Hippocampus), (Exercise OR physical activity) AND (ARC) AND (Hippocampus), (Exercise OR physical activity) AND (EGR-1 OR zif268) AND (Hippocampus). Results: Physical exercise can affect the expression of EGR-1, c-Fos, and ARC in the hippocampus, an important part of the brain involved in learning and memory. High-intensity physical exercise can increase c-Fos expression, indicating neural activation. Furthermore, the expression of the ARC gene also increases due to physical exercise. ARC is a gene that plays a role in synaptic plasticity and regulation of learning and memory, changes in synaptic structure and increased synaptic connections, while EGR-1 also plays a role in synaptic plasticity, a genetic change that affects learning and memory. Overall, exercise or regular physical exercise can increase the expression of ARC, c-Fos, and EGR-1 in the hippocampus. This reflects the changes in neuroplasticity and synaptic plasticity that occur in response to physical activity. These changes can improve cognitive function, learning, and memory. Conclusion: c-Fos, EGR-1, and ARC expression increases in hippocampal neurons after exercise, enhancing synaptic plasticity and neurogenesis associated with learning and memory.

Resultados: O exercício físico pode afetar a expressão de EGR-1, c-fos e ARC no hipocampo, uma parte importante do cérebro envolvida na aprendizagem e na memória. O exercício físico aumenta a expressão do gene c-Fos; sua alta intensidade pode aumentar a expressão de c-Fos, indicando ativação neural. Além disso, a expressão do gene ARC aumentou devido ao exercício físico, onde ARC é um gene que desempenha um papel na plasticidade sináptica e na regulação da aprendizagem e da memória, nas mudanças na estrutura sináptica e no aumento das conexões sinápticas, enquanto o EGR-1 também desempenha um papel na plasticidade sináptica, uma mudança genética que afeta o aprendizado e a memória. De maneira geral, o exercício físico regular pode aumentar a expressão de ARC, c-fos e EGR-1 no hipocampo. Isso reflete as mudanças na neuroplasticidade e na plasticidade sináptica que ocorrem em resposta à atividade física. Essas mudanças podem melhorar a função cognitiva, o aprendizado e a memória. Conclusão: A expressão de c-Fos, EGR-1 e ARC aumenta após o exercício físico nos neurônios do hipocampo, para aumentar a plasticidade sináptica, a neurogênese associada ao aprendizado e à memória.

RESUMO

Abstract Objectives: the first five years of life are critical for children's physical and intellectual development. However, the under-five mortality rate in South Asia and ASEAN is relatively high, caused by complex etiologies. This paper identifies maternal high-risk fertility behaviors and healthcare services utilization and examines predictors of under-five mortality (U5M) in 7 Asian (South Asia - ASEAN) developing countries (Indonesia, Myanmar, Cambodia, Philippines, Bangladesh, Nepal, and Pakistan). Methods: a multivariate logistic regression model with a complex survey was used to examine predictors of U5M on the frequency of U5M adjusted for comorbidities. Results: according to multivariate models (model 2), U5M was 2.99 times higher in mothers with low weight at birth infants than in mothers without low weight at birth infants (aOR= 2.99; CI95%=2.49-3.58); Mothers without antenatal care contacts were 3.37 times more likely (aOR= 3.37; CI95%=2.83-4.00) to have a U5M than mothers with eight or more antenatal care contacts; U5M in Indonesia was 2.34 times higher (aOR= 2.34; CI95%= 1.89-2.89). It is investigated that antenatal care serves as a predictor in decreasing U5MR. Conclusions: in order to achieve significant U5MR reduction, intervention programs that encourage antenatal care consultations should be implemented.

Resumo Objetivos: os primeiros cinco anos de vida são críticos para o desenvolvimento físico e intelectual da criança. No entanto, a taxa de mortalidade de menores de cinco anos no sul da Ásia e na ASEAN é relativamente alta, causada por etiologias complexas. Este artigo identifica comportamentos maternos de fertilidade de alto risco e utilização de serviços de saúde e examina preditores de mortalidade abaixo de 5 anos (MM5) em 7 países em desenvolvimento da Ásia (Sul da Ásia - ASEAN) (Indonésia, Mianmar, Camboja, Filipinas, Bangladesh, Nepal e Paquistão). Métodos: um modelo de regressão logística multivariada foi usado para examinar preditores de MM5 na frequência de MM5 ajustado para comorbidades. Resultados: na análise multivariada (modelo 2), U5M foi 2,99 vezes maior em mães com bebês com baixo peso ao nascer do que em mães sem bebês com baixo peso ao nascer (aOR= 2,99; IC95%=2,49-3,58); as mães sem contatos de cuidados pré-natais tiveram 3,37 vezes mais probabilidade (aOR=3,37; IC95%=2,83-4,00) para ter MM5 do que mães com oito ou mais contatos de cuidados pré-natais; MM5 na Indonésia foi 2,34 vezes maior (aOR= 2,34; IC95%= 1,89-2,89). Investiga-se que os cuidados pré-natais funcionam como um preditor na diminuição da MM5. Conclusões: para uma redução significativa da MM5, devem ser implementados programas de intervenção que estimulem as consultas pré-natais.

RESUMO

This study was conducted to determine the nutrient status, changes in the hematological and selected blood metabolites profile of mid-lactating dairy cows during wet and dry seasons under Indonesia's tropical environment. Forty mid-lactating FH cows were selected from the Livestock Farm Complex (Dairy Community) in Yogyakarta, with an average body weight of 421.77±28.60 kg and 1st to 3rd lactation. They were housed in a semi-open housing system with concrete flooring covered with rubber mats and provided with feeders and drinkers. They were fed twice daily, and drinking water was given ad libitum. Measurements were made on the intakes of feed (and nutrients). The variables measured were nutrient intakes, blood hematology, and metabolites profile and measured over two seasons, namely wet and dry seasons. The results of the measurements made were compared using independent t-test analysis. The result indicated that intake of CP, RLYM, RNEUT, NEUT, RBC, HGB, MCV, MCHC, MPV, albumin, urea nitrogen, and total protein was differed significantly (P < 0.05) between wet and dry seasons, respectively. It was concluded that the nutrient status of mid-lactating dairy cows in the wet season was higher than during the dry season, especially the intake of CP. In the wet season, it has a positive effect on the basic hematological parameters.

RESUMO

In tropical Indonesia, which has specific dry and wet seasons, it is difficult to provide high-quality forage in sufficient quantities throughout the year. Therefore, it is necessary to establish the availability and nutrient contents of forages and other natural feed resources during the dry and wet seasons in order to provide sufficient nutrients throughout the year, as an improvement effort the productivity of dairy cows. The method used was surveys conducted at dairy smallholder and groups selected in one of the areas of dairy cooperative in Yogyakarta; and observed environment condition (temperature and humidity). Feed samples were taken and analyzed in the Laboratory of Dairy Science and Milk Industry, Faculty of Animal Science UGM. Supplies of forages, agricultural by-products, feedstuffs, and commercial concentrates were available throughout the year, although the amounts were limited. Most of dairy smallholders had greater access to forages and agricultural by-products during wet season than during the dry season; this resulted directly in a better productivity of dairy cows during the wet season. In both seasons, farmers purchased commercial concentrates from other areas to support the cows feed requirements. Smallholder dairy farmers in the dairy areas of Yogyakarta had better access to forages and agricultural by-products during the wet season than during the dry season, but need to supplement their animals with commercial concentrates obtained from outside areas during both seasons. Assuring the continuity and availability of forages and concentrate in this area is of dire importance to reduce the dependency of feed from outside of the region.
