    This article presents the articulations of the Movimento Pela Base in conducting the process of building the Base Nacional Comum Curricular throughout the Brazilian territory. In a political and economic context influenced by the managerial discourse of reducing the role of the State, the Brazilian business sector has become a central figure in most of the policy recommendations for the educational field, as a result of an international growth trend in the third sector on actions public. The analysis of scientific productions about BNCC, considering books, articles, thesis and dissertations, in addition to documents made available on electronic media, allowed us to demonstrate the capillarity of the movement, the involvement of the subjects and public and private institutions, and their intentions to educate for the new capitalist sociability, based on the need to form consensus around the idea of a collective social project of public policy.Este artículo presenta las articulaciones del Movimento Pela Base en la realización del proceso de construcción del la Base Nacional Comum Curricular en todo el territorio brasileño.

    O cenário assimétrico e desfavorável da UFRJ: um diálogo sobre discentes com deficiência e a educação inclusiva

    Get PDF
    O tema central deste trabalho é o atendimento às necessidades educativas especiais de discentes com deficiência na Universidade Federal do Rio de Janeiro (UFRJ). Realizamos um estudo onde discentes com alguma deficiência e representantes de comissões de acessibilidade foram entrevistados, com perguntas semidiretas tratadas de maneira qualitativa. Nas considerações finais observamos que a UFRJ não abarca a questão em sua totalidade, sendo ela tocada apenas por ações esparsas. O tempo decorrido desde as leis para inserção de pessoas com deficiência no âmbito da educação inclusiva e a assimetria das ações impossibilita dizer que a Universidade como um todo enfrenta a questão

    The aim of the present study was to determine the water content limit for the cryopreservation of cajude-árvore-do-Cerrado (Anacardium othonianum Rizz) achenes and assess the effect of the thawing method on their performance. Achenes were dried in silica gel until water contents of 14, 12, 8 and 4% w.b. (wet basis) were reached and then were stored in cryogenic cylinders in direct contact with liquid nitrogen (-196°C) for 20 days; then, the achenes were subjected to slow, fast and microwave thawing. After thawing, the achenes underwent physiological evaluation and vigor tests. The water content limit for the cryopreservation of A. othonianum Rizz achenes was determined to be between 14 and 12% w.b. Water contents of less than 12% reduced the physiological quality and vigor of the achenes. The thawing method used did not affect the viability of the achenes for most features assessed; however, when thawed in a microwave, the achenes exhibited poorer performance, especially those that had 8% water content.Keywords: Preservation, desiccation, cryogeny, liquid nitrogenAfrican Journal of Biotechnology Vol. 12(22), pp. 3537-354

    Cloacoplasty in a 40-Day-Old Monk Parakeet with Cloacal Prolapse

    Get PDF
    Background: The monk parakeet (Myiopsitta monachus) is also known as the quaker parrot and belongs to the order Psittaciformes in the family Psittacidae. The cloaca is a posterior orifice common to reproductive, digestive and urinary systems and the cloacal prolapse is the displacement or inversion of its anatomic position. Nowadays, the non-conventional pet market in Brazil is rapidly growing, which demands more skills and competences from an avian veterinarian. This study case has as its main objective to present a 40-day-old monk parakeet (Myiopsitta monachus) with cloacal prolapse, treated using the cloacoplasty technique. It is important to mention that the occurrence of cloacal prolapse in this species and in such an early age is uncommon.Case: The patient presented 1 day before the physical examination an increased volume in the cloacal region and hematochezia, and diagnosed as cloacal prolapse. For the treatment, wounds were washed using physiological saline solution, ice and sugar were applied in order to reduce the edema, and mineral oil was used for repositioning the cloacal mucosa. Finally, local anesthesia was applied and 2 isolated contralateral sutures were done with the objective of reducing the sphincter’s diameter, without compromising the flow of urine and feces.  The monk parakeet was treated with antibiotic Avitrin®)  [oxytetracycline hydrochloride - 8.1 mg/mL] and a vermifuge [mebendazole 50 mg/mL]. A sample of feces was also obtained and sent to the Laboratory of Avian Pathology Diagnosis. The patient was discharged after 7 days of the treatment, obtaining a favorable result with no further complications.Discussion: The results of the coproparasitological examination were negative for the samples analyzed; nevertheless, the possibility of a false negative result cannot be totally dismissed. Cloacal prolapse may be related to cases of hypersexual disorder or overexertion to defecate due to intestinal parasites, posture, polyps, enteritis, neoplasm or cloacal hyperplasia. Besides that, endoparasitism is common in captive birds. For the correct treatment, proceed with a cloacoplasty, in which 1 or 2 simple sutures are made separated laterally in both sides, promoting the narrowing of the orifice. The surgeries such as the cloacoplasty are currently being defended, but in most cases as an adjuvant therapy. Cloacal prolapse in birds is a disease considered as an intestinal emergency. The techniques presented in this work demand sedation or anesthesia for the patient, which were not authorized by the tutor due to the high risk involved. However, due to the characteristic of domestication and docile behavior of the bird, it was possible to perform the 2 sutures with a local anesthetic block only. Cloacal prolapse is relatively common in adult psittacine birds, but uncommon in monk parakeets and young birds.  The treatment performed was effective for the monk-parakeet presented in this study case. The authors, however, would like to strongly reinforce the need to identify the cause of cloacal prolapse in order to properly treat it. The importance of correctly identifying the anatomy of a psittacine bird as well as applying precisely the suture techniques are the most important conclusions obtained, making both the identification of the problem and its solution through surgical intervention a simpler and successful process.Keywords: birds, endoparasites, suture, wild

    ANALYSIS OF THE INFLUENCE OF STATIC STRETCHING AND ECCENTRIC TRAINING ON FLEXIBILITY OF HAMSTRING MUSCLES

    Get PDF
    Previous studies have investigated the efficacy of stretching exercises and eccentric training in hamstring flexibility. The objective of this study was to comparatively investigate the efficacy of eccentric training and static stretching in flexibility gain, using a different eccentric training protocol. This study included 13 individuals having on average 23.15±1.72 years of age. The subjects were trained 3 times a week for 6 weeks and a pre- post- comparative analysis was conducted. It was observed that both static stretching and eccentric training resulted in the same non-significant gains in hamstring muscle flexibility. Probably eccentric training is a better training strategy for being able not only to increasing flexibility but for being able to increase strength and protect against muscle damage

    PIGMENTARY UVEITIS ASSOCIATED WITH IRIDOCILIARY CYSTS IN AMERICAN BULLDOGS

    Get PDF
    Presence of iridociliary cysts may cause a specific form of uveitis not associated with any known systemic disease or underlying cause. The condition was previously characterized in golden retrievers. However, Labrador retrievers, Great Danes and Boston terriers are reported to develop a similar disease condition. The following report documents seven cases of iridociliary cysts, with or without associated pigmentary uveitis, in American bulldogs from Brazil and Spain. Although not an uncommon disease, this syndrome has been relatively infrequently documented in the literature, with only one study in the American bulldog. This article describes clinical findings as well as medical and surgical management of each case. Because some of the patients were closely related in this series, a possible hereditary basis is considered for pigmentary uveitis associated with iridociliary cysts in American bulldogs

    Macro- and microscopic brain anatomy of the amazon lava lizard (Tropidurus torquatus) (WIED, 1820)

    Reptiles have a key role in understanding amniotes’ reproductive independence of water. Many adaptations arose, including in locomotor patterns and behaviours, and the nervous system adapted to those new habits. We have described the macroscopic anatomy and cytoarchitecture of the Amazon Lava Lizard brain (Tropidurus torquatus), an abundant lizard in South America. Fifteen specimens were captured, euthanized and their brains were dissected, eight of these were processed and stained in haematoxylin-eosin. Their main areas of the brain are the telencephalon and diencephalon, in the forebrain, tectum and tegmentum, in the midbrain and bulbota and cerebellum, in the hindbrain. The main and accessory olfactory bulbs are the most rostral structure of the brain and are composed of six layers. Brain hemispheres compose the telencephalon and are divided in pallium and subpallium. Medial, dorsomedial, lateral and dorsal cortices are part of the pallium. Striatum, pallidum and septum compose the subpallium. The diencephalon is composed of thalamus, epithalamus and hypothalamus. The midbrain has a ventral tegmentum, composed of torus semicircularis and a dorsal 14 layered optic tectum. Most part of the hindbrain is composed of the bulbo, and the cerebellum arises from it, forming a three-layered plate like structure. In general, the brain of Tropidurus torquatus resembles those of other lizards, with its own adaptations. Keywords: histology; lizard; morphology; reptile; nervous system

    The combination of pre- and post-emergence herbicides may affect their selectivity to soybean plants, especially to short-cycle cultivars. The objective of this work was to evaluate the selectivity of pre- and post-emergence herbicides to very-early maturing soybean cultivars. Two field experiments were conducted, one in Mandaguaçu, Paraná (E1) and other in Rio Verde, Goiás (E2), Brazil, using a 4×7 factorial arrangement. The treatments consisted of four pre-emergence herbicide managements (S-metolachlor at 1440 g ha-1, diclosulam at 25.2 g ha-1, sulfentrazone at 300 g ha-1, and no herbicide application); and seven post-emergence herbicide managements (lactofen at 120 g ha-1, chlorimuron-ethyl at 12.5 g ha-1, bentazon at 720 g ha-1, lactofen at 120 g ha-1 + chlorimuron-ethyl at 12.5 g ha-1, glyphosate at 900 g a. e. ha-1, two sequential glyphosate applications at 720 g a. e. ha-1 each, and no herbicide application). The early-maturing soybean cultivars evaluated showed sensitivity to the herbicides used. The combined use of pre- and post-emergence herbicides increased the occurrence of injuries in the plants. Diclosulam and sulfentrazone were the least selective pre-emergence herbicides. All herbicide combinations used affected soybean grain yield in E1; lactofen, chlorimuron, and bentazon presented the least selectivity in E2.The combination of pre- and post-emergence herbicides may affect their selectivity to soybean plants, especially to short-cycle cultivars.
