Subdoses de glyphosate no desenvolvimento de espécies arbóreas nativas

Recovery of degraded areas aims to provide the degraded environment favorable conditions for restructuring in an environment that is unable to regenerate itself and planting of tree seedlings is one of the effective ways to extend this process. However, native tree species have slow growth rate which increases the seedlings production time as well as decreases their competitiveness with weeds in areas of forests deployment. The aim of this study was to evaluate the effects of glyphosate reduced rates application on Psidium cattleyanum (yellow guava), Citharexylum myrianthum (pau-viola) and Cedrela odorata (cedro) seedlings development by analyzing its morphophysiological parameters. The experiment was carried out in greenhouse conditions and the experimental units consisted of one plant were conducted in 2.5L plastic pots and arranged in a completely randomized design with six replications. Treatments consisted of glyphosate application at 0, 7.5, 15, 30 and 60 g ha(-1) using Scout (R) commercial formulation. Treatments application on these species seedlings was realized 120 days after seeds germination. Visual evaluations of plants phytotoxicity were realized at 7, 14 and 21 days after treatments application and plants survival, stomatal conductance, height, stem diameter and dry mass of shoots were evaluated 90 days after treatments application. Different doses of glyphosate did not cause plants phytotoxicity. Already, 30 and 60 g ha(-1) of glyphosate provided greater increases in height, stem diameter and dry mass of shoots for Citharexylum myrianthum and Psidium cattleyanum, respectively.

Chemical composition and in vitro digestibility of fresh sugarcane hydrolysed with calcium oxide (CaO)

The objective was to evaluate the chemical composition and in vitro digestibility of sugarcane hydrolysed with increasing doses of calcium oxide and varying air exposure times. A completely randomised, split plot design was used; the doses were allocated to the plots, and the air exposure times were allocated to the subplots, with four repetitions. The data underwent analysis of variance and were laid out according to the effect of the treatment on the components of polynomial regressions, and evaluated at the 5% probability. The increase in the dosage negatively affected the quantities of neutral-detergent fibre (NDF), acid-detergent fibre (ADF), lignin (LIG), total carbohydrates (TC), cellulose (CEL), crude protein (CP), and ether extract (EE); and positively affected the quantities of non-fibrous carbohydrates (NFC) and mineral matter (MM). The addition of calcium oxide improved the in vitro digestible dry matter (IVDMD) coefficients and was able to keep up to 72 hours. The in vitro digestibility of the neutral-detergent fibre (IVDNDF) and of the acid-detergent fibre (IVDADF) coefficients decreased when calcium oxide was added. Calcium oxide has the ability to hydrolyse the fibrous fraction and conserve chopped sugarcane. Doses of 0.5 and 1.0% lime exhibited similar results to those achieved at higher doses; therefore, higher doses are not required in the hydrolyses of sugarcane. Over time, the sugarcane deteriorates, but this deterioration is reduced by the addition of calcium oxide.

Carcinoma de lábio com prognóstico sombrio devido conduta médica inadequada

The Squamous Cell Carcinoma is what more happens among the oral cancers, being considered sweats incidence in more than 90%. As important prognostic factor competes the early diagnosis and the immediate institution of the treatment, that it can involve radiotherapy and chemotherapy besides the surgery. The initial lesions don’t offer great diagnostic difficulties and now complemental laboratory exams define the diagnosis quickly, In the present report, the initial medical conduct was inadequate, with incomplete interpretation of the laboratorial result and adoption of inadequate therapeutic conduct, what resulted in constant evolution of the lesion. The patient came to the consultation with that medical history, after six months of the first attendance accomplished in another center. To the physical exam, infiltrative ulcerated lesion was observed in the lower lip, with having accentuated tissue loss superficially. The patient accused spontaneous pain and she did use an ointment, recommended six months ago for occasion of the first attendance. As diagnostic conduct was indicated the accomplishment of cytology and biopsy, being defined the diagnosis of Squamous Cell Carcinoma. The patient was immediately guided to the medical service of its municipal district for manegement of the specialized oncologic treatment. The patient was submitted the surgery followed by radiotherapy, being verified involvement of another structures by contiguity. Now, the patient meets abed, without viable perspectives of cure. The present report emphasizes the importance of the clinical knowledge and professional responsibility in attendance of cases of that nature.

The homeostasis of iron, copper, and zinc in paracoccidioides brasiliensis, cryptococcus neoformans var. Grubii, and cryptococcus gattii: a comparative analysis

Iron, copper, and zinc are essential for all living organisms. Moreover, the homeostasis of these metals is vital to microorganisms during pathogenic interactions with a host. Most pathogens have developed specific mechanisms for the uptake of micronutrients from their hosts in order to counteract the low availability of essential ions in infected tissues. We report here an analysis of genes potentially involved in iron, copper, and zinc uptake and homeostasis in the fungal pathogens Paracoccidioides brasiliensis, Cryptococcus neoformans var. grubii, and Cryptococcus gattii. Although prior studies have identified certain aspects of metal regulation in Cryptococcus species, little is known regarding the regulation of these elements in P. brasiliensis. We also present amino acid sequences analyses of deduced proteins in order to examine possible conserved domains. The genomic data reveals, for the first time, genes associated to iron, copper, and zinc assimilation and homeostasis in P. brasiliensis. Furthermore, analyses of the three fungal species identified homologs to genes associated with high-affinity uptake systems, vacuolar and mitochondrial iron storage, copper uptake and reduction, and zinc assimilation. However, homologs to genes involved in siderophore production were only found in P. brasiliensis. Interestingly, in silico analysis of the genomes of P. brasiliensis Pb01, Pb03, and Pb18 revealed significant differences in the presence and/or number of genes involved in metal homeostasis, such as in genes related to iron reduction and oxidation. The broad analyses of the genomes of P. brasiliensis, C. neoformans var. grubii, and C. gattii for genes involved in metal homeostasis provide important groundwork for numerous interesting future areas of investigation that are required in order to validate and explore the function of the identified genes and gene pathways.

Uma proposta de psicoterapia breve para paciente com escoriação psicogênica

Psychogenic Excoriation is a psychodermatosis characterized by skin alterations connected to mental processes, which are more common in women. It generates a considerable physical and psychosocial discomfort to the patient, because of the skin lesions. These patients assume to injure their own skin, and it differentiates this diagnosis from the factual dermatitis. This acknowledgement facilitates the insertion of these patients in psychotherapeutic processes, including fast psychotherapy, which can benefit them, especially in hospital contexts such as hospital ambulatories specialized in dermatology. Fast dynamic psychotherapies are described, analyzed and recommended to a psychogenic excoriation patient while introducing the process plan indicated to her. It relates to the clinical study of cases with medical records, psycho interviews and results of the FPI (Factor Personality Inventory). Based on these data, a fast psychotherapy is suggested with defined focus, aim and time, with a therapeutic plan according to what’s recommended in this type of treatment. The main objective is the symptom alleviation besides self-knowledge and insights, clarifying the most important identified psychodynamic conflicts. It’s also suggested that the suggested fast psychotherapy process could well result in important therapeutic gains to the analyzed patient.

O grito de um é a soma do grito de todos; escutam?

O tema proposto para o 18º COLE é intrigante: “O mundo grita. Escuta?” Vale-se de uma afirmação e de uma interrogação com verbos de conotações diversas, num entrelace quiasmático da linguagem. Enfocando esta proposição, nosso objetivo é examinar conotações e atos de linguagem que perpassam o referido tema. Para tanto, utilizaremos como corpus a tela: “O grito”, de Munch; um capítulo de “Memórias póstumas de Brás Cubas”, de Machado de Assis; a crônica “Diálogo de todo dia”; de Carlos Drummond de Andrade; a música: “Sinal fechado”, de Paulinho da Viola; e cinco aulas do escritor argentino Jorge Luis Borges, in: “Borges oral & sete noites”, destacando que, apesar de o mundo pretender comunicar-se, o que resta é uma dúvida quanto à consecução de seu escopo. Os textos focados vão para a oralidade: pela representação iconográfica do grito, em Munch; pelo diálogo tipográfico, em Machado; pela conversa psitacista, em Drummond; pela conversa de tempo marcado, em Paulinho da Viola; e pela força da oralidade de um escritor cego, Nobel de Literatura. Várias linguagens representam o grito do mundo e outras escutam. Representações das artes plásticas e literárias fazem-nos refletir sobre a recusa de escutarmos os gritos de cada indivíduo, em solilóquios que se somam, mas continuam sendo, apenas, ouvidos, sem resposta concreta, pois, frequentemente, as redes sociais tomam lugar da oralidade. Embora haja diálogos, o grito individual está dentro do grito do mundo e o escutar resulta de um ato perlocutivo, impondo ao enunciatário uma resposta, uma ação.

A quantidade de milho influencia na proliferação de gorgulho? aspectos teóricos que subsidiam o processo de construção de dados de uma investigação

The investigative practice as science teaching activity is recognized as an alternative to the learning improvement of science, becoming a perspective of work for teachers. This article arose from a study about the teachers formation process in the scope of investigative practices, conducted with trainee teachers of the Science Club of the Federal University of Pará - UFPA and students of basic education in public schools in Belém city, in order to discuss the theoretical-practical relationship in the planning of an investigative activity. In this process, some episodes indicate the necessity of such relationship, because in its absence the planning process shows itself to be questionable. Our analysis shows the importance of considering the theoretical context to conceive the planning and decisions regarding the conduction of the investigative practices, and oriented to a theoretical or practical goal.

Análise fisico-química e legalidade em bebidas de laranja

The aim of this paper was to measure the total soluble solids content (°Brix), titrable total acidity (AT) and ratio in orange beverages, such as frozen concentrated juice, not from concentrate juice, nectar and soft drink and to compare them with their Quality and Identity Standards (PIQ) published by the Ministry of Agriculture, Livestock and Food Supply (MAPA) and Codex Alimentarius. Four orange frozen concentrated juices, twenty two juices, seven nectars and thirteen orange soft drinks were analyzed. All frozen concentrated orange juices were in agreement with Codex Alimentarius. The majority of not from concentrated orange juices and soft drinks was in accord to Brazilian legislation. The orange nectars could not be compared with the standards because they are not published by MAPA or Codex Alimentarius.
