Aspectos biométricos dos frutos e diásporos de Mauritia flexuosa provenientes do Cerrado brasileiro

The buriti palm (Mauritia flexuosa L. f.) serves as a raw material for the food, pharmaceutical and biotechnological industries but it has a low germination rate and seed viability, which are directly related to the morphological characteristics of the fruits and seeds. Biometric characterization provides information necessary for the differentiation, characterization of ecological and genetic aspects of different species and populations of the same group, and can help in the conservation and propagation of species. The current work performed the biometric characterization of fruits and diaspores of Mauritia flexuosa from a cultivation environment in the Brazilian Cerrado. 100 fruits were randomly sampled, which were measured in length, width, thickness, individual weight, diaspore length, diaspore width, diaspore thickness and individual diaspore weight. Fruits were classified as red (Hue 10 R 4/8) and yellow-orange diaspores (Hue 7.5 YR 8/8). Data for each characteristic were submitted to descriptive statistical analysis. The fruits varied by 6.56% in length, 4.38% in width and 4.26% in thickness while the diaspores varied by 8.17% in length, 9.29% in width and 9.62% in thickness. The variables fruit weight and diaspore weight showed the greatest variations, 12.12% and 23.86%, respectively. There was a positive correlation between width and thickness (0.90). The small variation in biometric dimensions indicates that the species has little variability.A palmeira buriti (Mauritia flexuosa L. f.) serve como matéria-prima para a indústria alimentícia, farmacêutica e biotecnológica, porém apresenta baixa taxa de germinação e viabilidade de sementes, que estão diretamente relacionadas com as características morfológicas dos frutos e sementes. A caracterização biométrica fornece informações necessárias para a diferenciação, caracterização de aspectos ecológicos e genéticos de diferentes espécies e de populações de um mesmo grupo, podendo auxiliar na conservação e propagação de espécies. Dessa forma, o presente trabalho realizou a caracterização biométrica de frutos e diásporos de Mauritia flexuosa provenientes de um ambiente de cultivo no Cerrado brasileiro. Foram amostrados aleatoriamente 100 frutos, que foram mensurados em comprimento, largura, espessura, peso individual, comprimento do diásporo, largura do diásporo, espessura do diásporo e peso individual do diásporo. Os frutos foram classificados como vermelhos (Hue 10 R 4/8) e os diásporos amarelo-alaranjados (Hue 7.5 YR 8/8). Os dados de cada característica foram submetidos à análise estatística descritiva. Os frutos apresentaram variação de 6,56% de comprimento, 4,38% de largura e 4,26% de espessura, enquanto os diásporos apresentaram variação de 8,17% de comprimento, 9,29% de largura e 9,62% de espessura. As variáveis peso do fruto e peso do diásporo apresentaram maiores variações, 12,12% e 23,86%, respectivamente. Houve correlação positiva entre a largura e espessura (0,90). A pequena variação nas dimensões biométricas indica que a espécie possui pouca variabilidade

Germinação de sementes de Dypsis decaryi submetidas ao estresse salino em duas épocas

A palmeira triângulo (Dypsis decaryi), nativa de Madagascar e ameaçada de extinção em seu habitat, apresenta diversas características de interesse ornamental, tornando-a uma espécie importante para o mercado internacional. O principal método de propagação desta planta é por semente, que é influenciado por vários fatores como época de semeadura e salinidade. A variação de fatores ambientais em diferentes épocas de semeadura pode influenciar o processo de germinação enquanto que o estresse salino pode causar diminuição na germinação e até morte de sementes, afetando a produção de mudas. Desta forma, o objetivo deste trabalho foi avaliar o comportamento germinativo de sementes de Dypsis decaryi em diferentes concentrações salinas de cloreto de sódio (NaCl) e cloreto de potássio (KCl) em duas épocas. O delineamento experimental utilizado foi o inteiramente casualizado; o experimento foi realizado em esquema fatorial 2 x 2 x 5, sendo duas épocas de condução do experimento (verão e inverno), dois tipos de sais (NaCl e KCl) e quatro concentrações salinas (25, 50, 75 e 100 mM) e ausência de sais - controle; foram quatro repetições e 25 sementes por parcela. Foram avaliadas porcentagem de germinação, índice de velocidade de germinação e tempo médio de germinação. A espécie se mostrou tolerante à salinidade simulada por KCl e NaCl, durante o processo de germinação de sementes, o qual foi influenciado pela época de semeadura, concentrações salinas e interação entre épocas e concentrações. Não houve efeito significativo de forma isolada entre os tipos de sais, para interação de épocas e sais e, entre os três fatores avaliados

Biometry and storage of Triangle Palm seeds

Studies on biometry are considered important tools for understanding the germination process of seeds. Moreover, the ex-situ con- servation of palm seeds can cause loss of viability over time. The present study aimed to evaluate the biometric characterization and the effect of storage on the seed germination of the Triangle Palm (Dypsis decaryi), a widely used species in Brazilian landscaping. Two independent studies were conducted: I) biometric characterization of diaspores and II) effect of storage in seed germination. For biometry, a sample of 100 diaspores was used and the length, width and thickness were measured. Biometric data were ana- lyzed using descriptive statistics and correlation analysis. The seeds were packed in transparent plastic bags kept in a refrigerator (20 ± 2 ºC and 80% relative humidity) for storage evaluation. The experimental design was entirely randomized. The treatments consisted of six storage periods (0 - control, 30, 60, 90, 120 and 150 days); there were four repetitions and 25 seeds per plot. The germination percentage and germination speed index were evaluated. Diaspores showed little variation in their biometric charac- teristics, with a mean of 18.39 mm in length, 16.10 mm in width and 15.96 mm in thickness. There was significant and positive correlation between all biometric characteristics. It was observed that germination remained stable until 30 days of storage (90%), with a gradual percentage decrease in later periods. The seed storage allowed to maintain its viability and longevity with the ability to germinate, reaching a germination percentage of 63% after 150 days of storage

Growth-promoting microorganisms in the development of orchid seedlings of Phalaenopsis, Cymbidium, and Dendrobium genera

The demand for sustainable agricultural production systems is increasing, and using growth-promoting microorganisms in plants has stood out because it decreases or even replaces chemical fertilizer use, reducing production costs. This study aimed to evaluate the response of some microorganisms applied to the seedlings of primary orchids cultivated in Brazil (Phalaenopsis sp. 'Taisuco Swan', Cymbidium atropurpureum, and Dendrobium secundum). The experimental design was completely randomized. There were seven treatments (absence of microorganisms – control, Trichoderma sp. in sodium alginate, Trichoderma sp. in clay, Trichoderma sp. in sodium alginate and clay, Trichoderma sp. in a liquid medium, Azospirillum brasilense + Bacillus subtilis in a liquid medium, and Bacillus pumilus in a liquid medium), four replications, and three plants per plot. The seedlings were grown in a greenhouse and evaluated 190 days after microorganism inoculation. The evaluation of morpho-physiological characteristics differed according to the particularities of each genus. The Bacillus pumilus and Azospirillum brasilense + Bacillus subtilis rhizobacteria in a liquid medium for Phalaenopsis sp. 'Taisuco Swan' and the Trichoderma sp. fungus in a liquid medium for Cymbidium atropurpureum increased seedling growth and development. Azospirillum brasilense + Bacillus subtilis in a liquid medium for the Dendrobium secundum orchid promoted more root biomass. Using beneficial microorganisms in orchid cultivation is promising, and seedling growth and development depend on their inoculation and the morpho-physiological characteristics of each plant

Importance of Early Recognition of Arterial Hypertension in Children and Adolescents: The Nursing Function in Ambulatory Monitoring

Arterial hypertension is considered an epidemic, remaining as the main cause of death and global disability. As high blood pressure in childhood is highly predictive of high blood pressure in adulthood, there has been a growing interest in the early recognition of this condition in the pediatric population, through outpatient screening in children over three years of age. Objective: to emphasize the importance of routine monitoring of blood pressure measurement in children and adolescents in childcare consultations. Methodology: This is a literature review of published articles, searched through the PubMed, Virtual Health Library and Google Scholar databases. Results: 12 scientific articles were selected as the data source for the present study, seven in English and five in Portuguese. Conclusion: the measurement of blood pressure in all consultations with children is important. If the disease is identified, treatment must be instituted, which will vary between non-pharmacological and pharmacological therapies, which should be introduced for all pediatric patients with blood pressure values above the acceptable percentile for age. In this sense, it is pertinent that nurses acquire and develop skills that make it possible to implement strategies for the prevention of hypertension, as well as the early identification of children and adolescents at risk of arterial hypertension

Produção sustentável de mudas de amendoim-do-campo para uso na arborização urbana / Sustainable production of peanut seedlings for use in urban afforestation

A necessidade de estudar a utilização dos resíduos de tratamento de esgoto como substrato é de grande importância ambiental para solucionar os problemas de contaminação do solo e de corpos d’água provocados pelo despejo incorreto dos efluentes no ambiente e melhorar a qualidade da formação de mudas para paisagismo e arborização urbana. O estudo deste material foi avaliado com o desenvolvimento de mudas de amendoim-do-campo (Platypodium elegans Vogel) em diferentes concentrações de biossólido e terra de subsolo. O experimento foi instalado no Departamento das Ciências da Produção Agrícola da Faculdade de Ciências Agrárias e Veterinárias – UNESP, Campus de Jaboticabal. O delineamento experimental foi inteiramente casualizado. Foram seis tratamentos, oito repetições e quatro plantas por parcela. Os tratamentos testados foram constituídos por substratos resultantes da mistura de terra de subsolo (TS) e biossólido (BIO) em diferentes proporções: 100% TS (controle); 80% TS + 20% BIO; 60% TS + 40% BIO; 40% TS + 60% BIO; 20% TS + 80% BIO; T6 100% BIO. Para acompanhar o desenvolvimento das mudas de amendoim-do-campo, foram avaliados: altura da parte aérea (cm), comprimento da raiz (cm), diâmetro do coleto (mm), número de folhas, área foliar (cm2), e massa seca da parte aérea, das raízes e total. As características foram avaliadas assim que as raízes das plântulas puderam ser observadas na extremidade inferior dos tubetes. Da análise dos resultados, possibilitou-se concluir que os substratos estudados promoveram diferenças significativas para praticamente todas as características avaliadas das mudas de P. elegans, não existindo significância apenas para comprimento da raiz. As maiores concentrações de biossólido apresentaram os melhores resultados no desenvolvimento das mudas de amendoim-do-campo

Nursing care in combating and preventing the risks of hospital infection

The aim of this study was to understand the factors predisposing to the development of hospital infections, as well as to explain the risks of contracting hospital infections to which patients and professionals are exposed in hospitals. The study was conducted through a narrative review research, with the collection of data in books, official publications of the health area and, mainly, published articles. Through this study it was possible to conclude that there are numerous biological risks to which nurses, other health professionals and patients are exposed, which predisposes them to the development of hospital infections. Therefore, it is necessary that nurses receive instructions and training on the biological risks to which they are exposed, as well as on the need for the use of personal protective equipment and other precautionary measures. Here is the warning about the importance of adopting biosecurity measures to avoid exposure to these risks

Alvarado’s Criteria for Diagnosis of Children’s Acute Apendicitis

Acute abdomen in children is a condition that causes great distress to parents, and appendicitis is its most common cause, being more frequent at school age. This pathology is the cause of numerous visits to public and private hospitals around the world, and brings several complications. It is important that the health team is aware of the possibility of appendicitis in children, due to its high incidence and difficulty in establishing its diagnosis, because the symptoms are nonspecific and there are different clinical presentations. Objective: to explain the importance of the Alvarado criterion for the diagnosis of acute childhood appendicitis. Methodology: This is an integrative bibliographic review, in articles published in the PubMed, Virtual Health Library and Google Scholar databases. For the search for data, the descriptors “Acute abdomen”, “Appendicitis”, “Children” and the keyword “Alvarado score” were used. Data were collected in December 2020. Results: 16 articles were selected as the final sample for analysis of the review, six in English, nine in Portuguese and one in Spanish. Conclusion: Through this review it can be concluded that the use of the Alvarado Score for the diagnosis of acute appendicitis in children is useful and effective, avoiding the use of imaging tests in patients with a score above 7 on this scale

The exposure to formaldehyde causes renal dysfunction, inflammation and redox imbalance in rats.

Twenty-eight Fischer male rats were divided into four groups: control group (CG), exposed to the ambient air, and groups exposed to formaldehyde (FA) at concentrations of 1% (FA1%), 5% (FA5%) and 10% (FA10%). Kidney function was assessed by dosage of uric acid, creatinine and urea. Morphometry was performed on the thickness of the lumen of Bowman's capsule and diameter of the lumen of the renal tubules. We evaluated the redox imbalance through the catalase and superoxide dismutase activity as well as oxidative damage by lipid peroxidation. Inflammatory chemokines CCL2, CCL3 and CCL5 were analyzed by enzyme immunoassays. There was an increase in the concentration of urea in FA10% compared with CG and FA1%. The levels of creatinine, renal lumen and lipid peroxidation increased in all FA-treated groups compared with CG. The concentration of uric acid in FA10% was lower compared with all other groups. There was an increase in the space of Bowman's capsule in FA5% and FA10% compared with CG and FA1%. However, the superoxide dismutase activity was higher in FA5% compared with other groups while CCL5 was higher in FA1% compared with CG. The exposure to formaldehyde in a short period of time leads to changes in the kidney function, inflammation and morphology, as well as promoted the increase of superoxide dismutase activity and oxidative damage
