Use of crushing residue as nutrients source in the cocoa seedlings development in Medicilândia – PA

The use of milled rocks has been postulated as an efficient way to provide nutrients to the plants. The objective of this work was to evaluate the cocoa seedlings agronomic performance in different Diabase Penatecaua powder treatments. The study comprehends the following phases: i) involved waste characterization, ii) treatments definition and sampling; iii) monitoring and evaluation; iv) systematization and results discussion. The experiment was realized with cocoa seedlings germinated in commercial organic substrate in the period from July to September 2019. The used rock dust was extracted at Km 85, Transamazônica highway, Medicilândia municipality – Pa. The extraction area lithology is formed by igneous rocks of Diabase Penatecaua. The experimental delineation was entirely randomized, with four repetitions per treatment, being them respectively in the dosages 0, 25, 50 and 75 (g / plant), being 16 plants per block, totaling 64 plants, and their irrigation done manually in the first hours of the day. Therefore, the results showed that the dosages were absorbed by the cocoa seedlings according to the plant\u27s need allied to pH balance, which was caused by good nutritional cycling with the organic matter high rate present in the commercial substrate when in contact with the Diabase Penatecaua powder worked granulometry. However, the experiment time wasn’t enough to obtain statistically a significant difference. Thus, it is necessary that new studies be done aiming the temporal deepening of the studied doses for the culture

Objetivou-se avaliar o conhecimento materno acerca dos cuidados de higiene prestados ao recém-nascido. Estudo descritivo e transversal realizado com 150 puérperas do alojamento conjunto de uma maternidade de Fortaleza- Ceará. Os dados foram coletados, entre janeiro e abril de 2010, por meio de entrevistas e analisados com auxílio de estatística descritiva. Verificou-se maior conhecimento das puérperas acerca da frequência do banho e da temperatura da água, sequência de execução do banho, material para higiene íntima, fixação da fralda, frequência da limpeza do coto umbilical e necessidade de higienização oral. A maioria desconhecia não ser necessário higienizar os mamilos antes da mamada, os produtos para banho, sequência para higienizar a região íntima, cobertura do coto e produtos para higienização deste. Ressalta-se a importância das atividades educativas do enfermeiro no pré-natal e puerpério que auxiliem as mães nos cuidados de higiene do recém-nascido.This descriptive, transversal study aimed to evaluate mothers’ knowledge about measures of hygiene applied to new-borns. It was carried out with 150 women who had recently given birth in a maternity ward in the city of Fortaleza in the state of Ceará. The data was collected between January and April 2010 through interviews, and was analyzed with the aid of descriptive statistics. It was ascertained that the new mothers knew most about frequency of bathing and bathwater temperature, the sequence of events involved in bathing a new-born, products for ‘tailing’ the baby (washing its bottom and genitals), putting on the diaper, frequency of cleaning the umbilical stump and the necessity for oral hygiene. The majority were unaware that it is not necessary to thoroughly clean the nipples before breast-feeding and about bath products, the sequence involved in cleaning the bottom and genitals, covering of the umbilical stump, and products for cleaning it. The study emphasizes the importance of nurse-led educational activities in the pre-natal and post-partum periods to help mothers with hygiene care of the new-born.Se objetivó evaluar el conocimiento materno acerca de los cuidados de higiene prestados al recién nacido.

Análise do desenvolvimento de cultivares de rúcula submetidas a diferentes tipos de substrato / Analysis of the development of arugula cultivars submitted to different types of substrate

A rúcula (Eruca sativa Miller) é uma hortaliça pertencente à família Brassicaceae, originadas de regiões mediterrâneas da Europa e Leste da Ásia, o consumo vem aumentando no mundo, não só pelo fato do crescente aumento da população, mas, também pela tendência de mudança de hábito do consumidor. Suas folhas são macias e moles quando jovens, possuem um sabor picante e são muito apreciadas em saladas se adaptam melhor em clima mais ameno de temperaturas entre 15 e 18°C. O objetivo do trabalho foi analisar o desenvolvimento de duas cultivares de rúcula (Cultivada e Apreciatta) em três tipos de substratos/tratamento diferentes, avaliando-se parâmetros como altura, número de folhas, comprimento radicular e peso de matéria seca da parte aérea e de raiz. O experimento foi conduzido na Universidade Federal do Pará-Campus Altamira/PA, em casa de vegetação com a instalação de um canteiro de chão com as dimensões de 140 x 140 cm e 24,5 cm de altura com três subdivisões iguais com área de 0,65m2. Sendo os tratamentos: T1 - substrato contendo Solo de Barranco; T2 –Solo de Barranco + Adubo Mineral (65g de NPK, na formulação 5-10-10) + Terra Preta (5kg) + Esterco Bovino (6L); T3 - Solo de Barranco + Terra Preta (5kg). Todas as sementes foram germinadas em copos plásticos, perfurados na base e contendo substrato de terra preta e após 16 dias de germinação, as mesmas foram transplantadas para o canteiro e após sete dias iniciou-se as coletas de dados dos parâmetros de número de folhas e altura. Conforme os resultados obtidos para os parâmetros de altura, número de folhas, comprimento radicular e peso de matéria seca da parte aérea e de raiz, as cultivares Apreciatta e Cultivada obtiveram melhores desenvolvimento no tratamento T2

Influence of Clinical Status and Parasite Load on Erythropoiesis and Leucopoiesis in Dogs Naturally Infected with Leishmania (Leishmania) chagasi

Background: The bone marrow is considered to be an important storage of parasites in Leishmania-infected dogs, although little is known about cellular genesis in this organ during canine visceral leishmaniasis (CVL). Methodology/Principal Findings: The aim of the present study was to evaluate changes in erythropoiesis and leucopoiesis in bone marrow aspirates from dogs naturally infected with Leishmania chagasi and presenting different clinical statuses and bone marrow parasite densities. The evolution of CVL from asymptomatic to symptomatic status was accompanied by increasing parasite density in the bone marrow. The impact of bone marrow parasite density on cellularity was similar in dogs at different clinical stages, with animals in the high parasite density group. Erythroid and eosinophilic hypoplasia, proliferation of neutrophilic precursor cells and significant increases in lymphocytes and plasma cell numbers were the major alterations observed. Differential bone marrow cell counts revealed increases in the myeloid:erythroid ratio associated to increased numbers of granulopoietic cells in the different clinical groups compared with non-infected dogs. Conclusions: Analysis of the data obtained indicated that the assessment of bone marrow constitutes an additional and useful tool by which to elaborate a prognosis for CVL

Higher Expression of CCL2, CCL4, CCL5, CCL21, and CXCL8 Chemokines in the Skin Associated with Parasite Density in Canine Visceral Leishmaniasis

Several previous studies correlated immunopathological aspects of canine visceral leishmaniasis (CVL) with tissue parasite load and/or the clinical status of the disease. Recently, different aspects of the immune response in Leishmania-infected dogs have been studied, particularly the profile of cytokines in distinct compartments. However, the role of chemokines in disease progression or parasite burdens of the visceralising species represents an important approach for understanding immunopathology in CVL. We found an increase in inflammatory infiltrate, which was mainly composed of mononuclear cells, in the skin of animals presenting severe forms of CVL and high parasite density. Our data also demonstrated that enhanced parasite density is positively correlated with the expression of CCL2, CCL4, CCL5, CCL21, and CXCL8. In contrast, there was a negative correlation between parasite density and CCL24 expression. These findings represent an advance in the knowledge of the involvement of skin inflammatory infiltrates in CVL and the systemic consequences and may contribute to developing a rational strategy for the design of new and more efficient prophylactic tools and immunological therapies against CVL

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
