Published: April 2020

Toxoplasma gondii merupakan parasit golongan protozoa intraseluler yang menyebabkan penyakit zoonosis yaitu toksoplasmosis. Gejala toksoplasmosis dapat berlangsung tanpa gejala hingga menimbulkan gangguan neurologis berat bahkan kematian pada individu immunocompromised. Infeksi Toxoplasma gondii (T.gondii) dapat terjadi secara kongenital maupun didapat. Respon imun host terhadap infeksi T. gondii dimulai saat parasit masuk ke dalam tubuh dan melakukan invasi intraseluler. Respon imun alamiah ini akan menghasilkan IFN-γ dan menginduksi mediator inflamasi yang dapat menghambat multiplikasi T.gondii serta menstimulus terbentuknya respon imun adaptif.Kata kunci: infeksi, respon imun,Toxoplasma gondii

Authors: Tater Jawaher M , Abdullah Bashar H , Hussain Wisam A 
Published: May 2020

BACKGROUND: Vascular tumors are a heterogeneous group of diseases with biological behavior ranging from a hamartomatous growth to frank malignant. The pathophysiology of lymphangioma, vascular malformation and hemangioma is interconnected, blood vessels known to be the site of origin of hamartomas, venous malformations and some neoplasms as benign, tumor-like growth of vessels (hemangiomas). Angiogenesis is the process of formation of new blood vessels from an existing structure.
Aims of study Assessment of angiogenic potential in benign vascular lesions (hemangioma, lymphangioma and lobular capillary hemangioma) of head and neck region.
Materials and Methods: Twenty-two formalin-fixed paraffin-embedded tissue blocks of Hemangioma/vascular malformation, thirty of lobular capillary hemangioma and another twenty of lymphangioma to be stained with Endothelial cell-Specific Molecule-1 (ESM-1) monoclonal antibody.
Results: Microvessel density expressed by Endothelial cell-Specific Molecule-1 (ESM-1) immunomarker was found in all cases with mean density of (37.44±23.16) for lobular capillary hemangioma and (25.02±13.89) for hemangioma and (6.34±3.52) for lymphangioma. According to post hoc test ESM-1 marker expression showed a high significant difference between (hemangioma and lymphangioma=0.001), (lymphangioma, pyogenic granuloma=0.000), and it was significantly different between (hemangioma, pyogenic granuloma=0.011)
Conclusions: The obvious capillary growth in lobular capillary hemangioma revealed that lobular capillary hemangioma showed the highest activity of angiogenic potential in comparison to hemangioma and lymphangioma.

Published: April 2020

This paper attempts to analyze the effects of zakat distribution on income inequality and welfare aspects of the poor Muslim society in Malaysia. The population of the study is the poor and hardcore poor of the zakat recipients in Selangor. Exploring the cross sectional micro level data of nine districts in Selangor, Malaysia, this study adopted Lorenz curve and Gini coefficient to represent positive measures of income inequality. However, these measures do not take into account the welfare effects of the distribution to the society. Hence, Atkinson index is adopted to represent the normative measures of inequality that takes into account the welfare effects of the zakat distribution to society. Results of the Gini coefficient and Lorenz curve have proven effectiveness of zakat distribution in reducing income inequality of the society. Whilst the theory of zakat says that zakat distribution will improve income inequality and welfare of the society, findings of the normative measures in this research show otherwise. Therefore, this study is extended with zakat distribution simulation model based on had kifayah. Results from the distribution simulation model proved the ability of zakat in narrowing down income inequality, reducing income loss and hence increasing the welfare of the society.
Solos e os serviços ecossistêmicos (Soils and the Ecosystem Services)
Authors: Vezzani Fabiane Machado 
Published: April 2020

Nesse texto, apresentamos uma visão sobre serviços ecossistêmicos. Para isso, definimos ecossistema e o papel do solo no seu funcionamento. Serviços ecossistêmicos são os benefícios que as pessoas obtêm dos ecossistemas. A história dos serviços ecossistêmicos aponta que o tema não é novo. Porém, após a Avaliação Ecossistêmica do Milênio, o termo serviços ecossistêmicos se consolidou e é tratado em várias áreas de conhecimento. Hoje, a busca do meio técnico-científico é para um procedimento adequado para avaliar e efetuar pagamento aos responsáveis por manter os serviços ecossistêmicos. Há cada vez mais evidências de que os serviços ecossistêmicos são atingidos em função da biodiversidade dos ecossistemas. Biodiversidade é a variabilidade de organismos vivos em todos os níveis biológicos, compreendendo a diversidade dentro de espécies, entre espécies e de ecossistemas. O papel do solo neste contexto consiste de que a biodiversidade de um ecossistema acontece a partir do solo. É por meio do solo que ocorre o desenvolvimento da estrutura vegetal e, assim, o fornecimento de energia e matéria para os demais seres vivos das teias alimentares terrestres. Um ecossistema biodiverso só é possível pelo manejo ecológico aplicado ao solo. A abordagem desse texto passa pela compreensão da biodiversidade como propulsora dos serviços ecossistêmicos, os princípios da sustentabilidade do planeta, as concepções de ecologia profunda e ecologia reconciliatória, e a conexão do homem na rede planetária. In this text, we present an overview of ecosystem services. We define ecosystem and the role of soil in its functioning. Ecosystem services are the benefits people obtain from ecosystems. The story of ecosystem services indicates that the subject is not new. However, after the Millennium Ecosystem Assessment, the term ecosystem services consolidated and it is treated in various areas of knowledge. Today, the demand of the technical and scientific people is for an adequate procedure to assess and make payments to those responsible for maintaining ecosystem services. There is increasing evidence that ecosystem services are affected due to the biodiversity of ecosystems. Biodiversity is the variability of living organisms in all biological levels, including diversity within species, between species and of ecosystems. The role of the soil in this context is that the biodiversity of an ecosystem takes place from the soil. It is through the soil occurs the development of the plant structure and thus provides energy and material for the remaining life of the terrestrial food webs. A biodiversity ecosystem is possible by the ecological management applied to the soil. The approach of this text involves the understanding of biodiversity as a driver of ecosystem services, the principles of sustainability of the planet, the ideas of deep ecology and reconciliatory ecology, and the human connection in the global network. Keywords: biodiversity, deep ecology, sustainability.

A adaptação climática de qualquer espécie vegetal tem estreita relação com seu padrão fenológico, influenciando na sua distribuição geográfica e sua flutuação nos ecossistemas. O objetivo do trabalho foi avaliar o comportamento de 33 híbridos (26 híbridos simples, 6 híbridos triplos e um híbrido duplo) geneticamente modificados de milho em situações climáticas contrastantes - épocas de semeadura (ES), sob irrigação. O delineamento experimental foi o de blocos casualizados com duas repetições. Os experimentos foram semeados em área da Embrapa Meio-Norte, município de Teresina, PI, em julho e setembro/2013. A temperatura máxima média no período do pendoamento ao espigamento na primeira época foi de 36,7 oC e na segunda época de 38,8 oC, contribuindo para uma redução na eficiência de uso da água (EUA) e dos componentes de rendimentos, números de espigas por área e do peso de espiga na ES de setembro. O rendimento de grãos e a EUA da ES de junho (9.876 kg ha-1; 17,3 kg ha-1 mm-1) foi superior em 25,1 % e 42,27 %, respectivamente, em relação a ES de setembro (7.900 kg ha-1; 11,97 kg ha-1 mm-1). Os híbridos AG 8041 PRO, 3646 HX, RB 9221 PRO, P 4225 H, 30 F 53 YH apresentam tolerância a altas temperaturas e usam melhor a água para a produção de grãos.

The climate adaptation of any plant species is closely related to its phenology, influencing on its geographical distribution and its fluctuation in ecosystems. The objective this work was to evaluate the performance of 33 hybrids (26 single hybrids, six triples hybrids and one double hybrid) genetically modified corn in contrasting climatic conditions (two sowing dates) under irrigation. The experimental design was a randomized complete block design with two replications. The experiments were sown in the Embrapa Mid-North, Teresina, Piauí State, in July and September / 2013. The average maximum temperature from bolting to heading during the first season was 36.7 °C and in second one was 38.8 oC, reducing the water use efficiency (WUE) and yield components, ear number per area and ear weight in september sowing. The grain yield and WUE of sowing June (9,876 kg ha-1, 17.3 kg ha-1 mm-1) was higher 25.1% and 42.27%, respectively, compared to sowing September (7,900 kg ha-1, 11.97 kg ha-1 mm-1). AG 8041 PRO, P 3646 HX, RB 9221 PRO, P 4225 H, 30 F 53 YH hybrids present tolerant to high temperatures and more efficient water use.
