Authors: Medeiros Lorrana Alves , Tiveron Carla Cristina Lopes Barbosa
Published: December 2021

Introduction: Headache is one of the most common complaints in medicine, being divided into primary or secondary. Idiopathic Benign Intracranial Hypertension (IBIH) is one of the causes of secondary headache, where there is an increase in intracranial pressure in the absence of an expansive process. Goals: To present the management of IBIH refractory to conventional treatment. Methodology: Clinical evaluation of the patient, review of her medical record and review of literature related to the topic. Case report: RMC, female, 55 years old, short stature, BMI 48, presented in 2018 repetitive pictures of severe headache, without improvement factors, associated with visual disturbances that evolved to amausore, sporadic loss of balance and slowing pupillary reflexes, mood disorders and easy cry. Magnetic resonance and fundscopy were inconclusive, and CSF puncture found an opening pressure of 20 cm of water. After CSF puncture, the patient showed instantaneous vision improvement, and therapy with Acetazolamide was introduced, which controlled and kept her ophthalmological symptoms stable. Angina conditions were only resolved with the introduction of Lamotrigine. RESULTS: The most commonly prescribed medication for IBIH, Acetazolamide, controlled the reported patient’s ophthalmological condition, but not the pain episodes. When this medication alone cannot control the condition, the association of other medications or surgical conduct is indicated. The association of Acetazolamide with Lamotrigine was extremely important to solve the patient’s pain episodes, making her clinical management positive. Conclusion: The combination of Lamotrigine and Acetazolamide has been shown to be an excellent form of outpatient treatment for IBIH.

Published: December 2021

Background: Bacterial meningitis is a serious infection that occurs in the Central Nervous System, which presents important morbidity and mortality, mainly in children. The main bacterial agents causing meningitis in the community are Haemophilus influenzae, Neisseria meningitidis and Streptococcus pneumoniae. Specific signs and symptoms suggest meningitis and cerebrospinal fluid analysis is the main exam leading to diagnosis. Objectives: To analyze the behavior of cerebrospinal fluid during the evolution of the patient with bacterial meningitis. Methods: A retrospective study revised the medical records of patients with bacterial meningitis confirmed by cerebrospinal fluid examination in the Base Hospital of São José do Rio Preto from January 1996 to December 2002. Results: in the 63 Patients, there were 18 cases (28.6%) of S. pneumoniae, 20 cases (31.7%) of H. influenzae, 12 cases (19%) of N.meningitides B and 13 (20.6%) cases of N. meningitidis C. In the 18 patients with pneumococcus, 10 (55.6%) were discharged and 8 (44.4%) died. In the 20 patients with HIB, only 3 (15%) died, there was no death patients with meningococcus B and C. Conclusion: There was no difference statistics in the cerebrospinal fluid of the patients who were discharged and those who died.

Context: Stroke, when affecting territories dependent on posterior circulation, affects the thalamus and mesencephalic structures, regions irrigated by the paramedian arteries and perforating arteries of the posterior communicating artery and posterior cerebral artery. However, there is an anatomical variant of the paramedian arteries, the Percheron artery, when occluded causes bilateral thalamic infarction. Case report: a 53-year-old woman who presented blurred vision, holocranial headache, hypertensive peak, decreased level of consciousness, anisocoria, conjugate eye deviation. Tomography was normal and after 48 hours there was periventricular hypodensity of white matter, corona radiate and bilateral thalamic. Cerebral angiography confirmed moderate stenosis in the cavernous segments of the internal carotid arteries. In the investigation, a heterozygous mutation for factor V of Leiden was found. The patient evolved well, after blood pressure control and secondary prophylaxis. Clinical picture brings the classic triad of Percheron Artery infarction: decreased level of consciousness, vertical changes in the look and cognitive changes in memory and learning. Other symptoms could be found hypersomnia, oculomotor paralysis and ataxia. The diagnosis is clinical and radiological by visualizing bilateral thalamic involvement. Predisposing factors should be investigated, such as the Leiden factor V mutation, which increases thromboembolic events. Conclusion: It is important to research risk factors and execute an early diagnosis for acute intervention and prophylaxis of stroke.
Huntington’s disease in a young patient: case report
Authors: Carvalho Nichollas de Lorenzi
Published: December 2021

Context: Huntington’s disease (HD) is characterized by a progressive, autosomal neurodegenerative disease dominant, characterized by motor, psychiatric manifestations and cognitive decline due to a genetic alteration with 36 to 121 CAG repetitions on chromosome 4, which leads to the mutation of the huntingtin protein and its nuclear accumulation with formations of cytoplasmic inclusions of the affected neurons. It being more common between the third and fifth decade of life. The aim of this study was to report the case of a young patient with HD. Case report: Female patient, 6 years old. Mother reports seizures for 3 years, associated with abnormal lower limb posture, as well as rapid shock-like limbs, lasting a few minutes, eye upwards, loss of consciousness, difficulties in swallowing and loss of ability to walk at 5 years of age. Mother reports family history of involuntary motor shocks. The neurological examination showed a vigil, global epasticity; Global hyperreflexia; Bilateral aquilean inexhaustible clonus; Plantar skin reflex in bilateral extension. Upon examination of the cranial nerves, presented isochoric and photoreactive pupils, preserved extrinsic ocular motricity, symmetrical face, tongue and palate symmetrical, trophism and neurovegetative functions without changes. Magnetic resonance imaging was requested, showing atrophy of the caudate nucleus, and research for Huntington’s disease, confirming the diagnosis. Conclusions: the reported case brings to light the rarity of the disease manifestation in younger patients and supposed correlation with family history, corroborating with the evidence of the factor disease as the main risk factor for the development of HD.

Authors: Oliveira Sayd Douglas Rolim Carneiro , Gadelha Carlos Jorge Maciel Uchoa , Mesquita Dara da Silva , Brito Tereza Cristina Ribeiro
Published: December 2021

Introduction: With the emergence of SARS-CoV-2 and its rapid spread, a concern with the pregnant women have increased, since viruses have a wide range of obstetric and neonatal issues. Recent findings indicate that the gestational period and the postpartum period make mothers and their offspring more susceptible to COVID-19 and the rapid progression to the critical stage of the disease. Objectives: To carry out a bibliographic study on SARS-CoV- 2 during pregnancy and the potential risk of neurodevelopmental disorders in neonates. Methods: A review, developed from articles selected on the following bases: PubMed, Web of Science and Scopus. In the search, articles indexed until March 2021 and published in English, using the descriptors: “COVID-19”; “Pregnancy”; “Offspring”; “Neonatal”; “Neurodevelopment”; “Anomalies” and “Complications”. Exclusion criteria: duplicates and articles outside the scope of the study. Results: The initial search resulted in 533 articles, 498 from PubMed, 2 from Web of Science and 33 from Scopus. After reading the title and abstract, the application of the inclusion and exclusion criteria, the sample of 48 documents were included. In the studies, 89.0% of all patients had cesarean delivery (n = 201), 33.3% had gestational complications, 35.3% had premature delivery and about 2.5% were stillborn or had neonatal death. Among those tested, 6.45% of neonates diagnosed positive for COVID-19. In another study, the newborn showed neurological issues similar to the adult patients and transient neurological complications due to cerebral vasculitis. Conclusions: The results demonstrate that further investigations are needed to determine the potential for vertical intrauterine transmission in pregnant women with COVID-19 and possibles fetal and neonatal consequences.

Published: December 2021

Context: Vogt-Koyanagi-Harada disease is an inflammatory disorder, which presents with intraocular, auditory and central nervous system involvement. It has two distinct courses: acute onset and chronic recurrence, whose differential diagnoses are, respectively, diseases of the optic neuromyelitis spectrum, and chronic meningitis. The diagnostic criteria developed by the international disease committee in 2001 classify patients into: probable disease (ocular findings only), incomplete (ocular plus cutaneous system or neurological manifestations) and complete (when the three forms occur together). Methods: Report the case of a patient seen at the emergency room of Santa Casa de São Paulo, diagnosed with Vogt-Koyanagi-Harada disease. Case report: 43-year-old woman, reporting occipital headache, with irradiation to the retro-orbital region, progressed to sudden bilateral amaurosis, in addition to conjunctival hyperemia. Neurological physical examination presented bilateral visual acuity (Snellen)> 20/200, poorly delimited optical discs. Uveitis and scleritis were also found. Brain and orbit MRI showed: bilateral retinal detachment, with small subretinal collections; regular thickening and impregnation of the choroid; tenuous episcleral impregnation; alteration of the sign of the inner ears, more evident in the cochleae; tenuous linear leptomeningeal impregnation at the level of the cerebellobulbar cistern. Liquor: 21 cells (99% lymphocytes), 31 proteins and 47 glucose, negative culture for bacteria. We proceeded to infusion 1000mg of methylprednisolone for 3 days, with daily use, subsequently, of prednisone 60mg, with significant improvement of the condition. Conclusions: It is a rare disease, but it must be recognized by every neurologist, since it is treatable and can leave serious visual sequelae.
Progressive thoracolumbar scoliosis culminating in the diagnosis of young pompe disease: case report
Authors: Silva Tarcisio Rubens da , Maia Rayana Elias , Nogueira Taísa de Abreu Marques
Published: December 2021

Introduction: Pompe’s disease is a neuromuscular condition caused by a metabolic disorder of autosomal recessive inheritance. The deficit of acid alpha-glucosidase causes accumulation of glycogen in the lysosomes of the striated and cardiac muscle. It presents in childhood: hypotonia and cardiorespiratory impairment; but at late-onset: axial and waist muscle weakness. Case report: Patient, female, 20 years old, non-consanguineous parents, with good intra-uterus fetal mobility, was born by cesarean delivery weighing 3.7 kilograms and 51 centimeters. She first walked without support and spoke her first words at 13 months of age. By the age of 12, she started progressive thoracolumbar scoliosis and underwent posterior spinal arthrodesis two years later. During the follow-up, muscle weakness was found. Furthermore, she presented macrocephaly, high myopia, fusion of cervical vertebrae, progressive scoliosis, dolichostenomelia and joint hypermobility. Extensive investigation was carried out with laboratory tests that showed CPK elevation, imaging tests and mutation research for facio-scapular-humeral muscular dystrophy and type 2A waistband muscular dystrophy. The incisional biopsy found mixed muscle changes with deposit of amorphous material. Pompe’s disease was confirmed by a significant reduction in alpha-glucosidase activity. The patient evolved with weakness in the legs and fatigue on moderate efforts, but also weakness in the lower limbs, detachable on the right and hyporeflexia, on physical examination. Conclusions: Progressive thoracolumbar scoliosis, refractory to postural and surgical corrections, should be an alert for differential diagnoses. Changes in axial musculature can be suggested and Pompe’s disease, a potentially treatable condition, must become relevant.
Possible mechanisms of action of cannabidiol in the epilepsies: a review
Authors: Cruz Leonardo Cardoso , Belotto Luis Gustavo Fraga , Machado Sofia Dias Campos , Moreira Fabrício de Araújo
Published: December 2021

Background: Cannabidiol (CBD) is a compound of Cannabis Sativa plant that has been studied since the 1970s for its effectiveness in the treatment of refractory epilepsies. With the discovery of the endocannabinoid system, most recent studies have been dedicated to elucidating its mechanisms of action. Objective: To review scientific articles in order to enlightening the antiepileptic cannabidiol’s mechanisms of action. Methods: Literature review on both PubMed and Google Scholar searching for the terms: “epilepsy”, “cannabidiol” and “mechanism of action”. Results: We found that cannabidiol has a lot of mechanisms of action which can explain its effectiveness, among which stand out: endocannabinoid system facilitation, by inhibition of recaption and hydrolysis of anandamide as well as by the facilitation of its synthesis and release. These processes must result in the indirect activation of CB1 and CB2 receptors. Furthermore, CBD promotes the activation of mTOR and PI3K proteins intracellular pathway, with subsequent reduction of glutamatergic release. Conclusions: The general hypothesis is that cannabidiol has antiepileptic effectiveness, even in cases of refractory epilepsies, precisely for showing several mechanisms of action. We emphasize, however, the necessity of more researches in this area for further enlightenment of theses possible mechanisms of action and the applicability in the treatment of epilepsies.
Analysis of the impact of Tominersen (IONIS-HTTRX/RG6042) in the treatment of Huntington’s disease: A systematic review
Authors: Fonseca Gustavo Soares Gomes Barros , Machado Maria Luiza Mendes , Bezerra Paulo Victor Protásio
Published: December 2021

Introduction: Huntington’s disease (HD) is a congenital pathology of a hereditary, neurodegenerative and progressive character, with a high mortality rate. This pathology is caused by repeated expansions of a single CAG codon in the gene encoding huntingtin. To date, several attempts to prevent and delay such a mutation have been carried out in patients. However, a promising drug, Tominersen, formerly called IONIS HTTRx/ RG6042, is in the testing phase and has shown a favorable therapeutic response, which acts directly on the messenger RNA of the gene encoding huntingtin (HTT). The drug, whose route of administration is intrathecal in bolus, intercepts and destroys the messenger before the corrupted protein can work. The present study aims to analyze the impact of Tominersen in the treatment of patients with HD and to evaluate its prognosis. Methods: The present study is a systematic literature review, in which an electronic search was performed in the PubMed, SciELO, Web of Science and Google Scholar databases. Results: In one of the double-blind randomized clinical trials (n = 46), 34 were assigned to receive the drug. The group that received Tominersen showed a decrease in the concentration of mutant HTT in cerebrospinal fluid after 28 days. In another study (n = 791), the GENERATION HD1 clinical trial is currently taking place and will last for 25 months. Conclusion: Tominersen decreases the concentration of HTT, that is, it suppressed the protein responsible for HD. Studies related to the drug are still very recent and require extra attention.

Published: December 2021

Aim: The aim of this study is to examine the relationship between upper extremity anaerobic power and arm volume with the correct service shooting rate of athletes interested in volleyball. A total of 13 male athletes playing elite level volleyball participated in the study. Method: Arm volumes were measured while the athlete was standing and legs were shoulder width apart. The distance between the acromion bone and the olecranon bone was measured with ± 1 mm accuracy at 10% intervals. Forearm volumes were measured while the athlete was standing and legs were shoulder-width apart. The distance between the olecranon bone and the ulnar styloid bone was measured with ± 1 mm accuracy at 10% intervals. To determine their anaerobic performance, Wingate anaerobic power and capacity test (AP) was performed on a pan arm ergometer, which was connected to a computer modified for this arm and operated with compatible software. The service speed (SS) of the athletes was used in Pocket Radar. Data evaluation was carried out using a statistical program in computer environment. "Shapiro-Wilk Test" was used for normal distribution of data. In statistical analysis, minimum and maximum values, arithmetic mean, standard deviation values were calculated. "Pearson" correlation analysis was used for the normally distributed data in the relationship of arm volume (AV) with anaerobic power. The data were evaluated according to the "0.05" significance level. Results: When the findings are examined, the AP and SS values of the athletes (r =, 843 **; p <, 001), RightAV values with SS (r = .857 **; p <, 000), LeftAV and SS values (r = .924 **; p <, 000) and significant relationship was found between Total AV and SS values (r =, 894 **; p <, 000). Conclusions: As a result, the findings of our study showed that men who do elite volleyball sports both have high upper extremity anaerobic power characteristics and have a high percentage of muscles around the arm, and play a decisive role in the correct service shooting speed.

The effect of differentiated instruction on academic achievement of grade eleven students in the field of derivative in Bhutan
Authors: Kado Kado , Dorji Nedup , Dem Nim , Om Dorji
Published: December 2021

Given the increasing diversity of students academically and culturally, educators are being called upon to accommodate students' diverse learning requirements through differentiated instruction strategies. In Bhutan, the Ministry of Education recently mandated the implementation of a differentiated instruction strategy in the K-12 curriculum. From this perspective, this study attempted to ascertain the effect of differentiated strategies on grade eleven mathematics students within the framework of the pre_test and post_test quasi-experimental research method. 64 grade eleven students participated in this study. The concept of derivative was taught using a differentiated instruction strategy for the experimental group (N=32) while a conventional one-size fits-all strategy was used for teaching the control group (N=32). A Conceptual Understanding Test on the Derivative (CUTD) was administered as pretest and posttest groups to examine the differences in their learning achievements. A t-test analysis of the pretests indicated no significant differences, indicating that the experimental and control groups' learning abilities on the concept of the derivative were roughly comparable. However, a statistically significant difference in favour of the experimental group over the control group was discovered in the post test analysis. It was recommended that Mathematics teachers and educators should embrace the use of differentiated instruction while teaching and learning derivative.The researchers also recommended that differentiated education be used over a prolonged period of time and with a larger sample size.

Published: December 2021

Human Pose estimation has grabbed the eye of the computer vision community for the past few decades. It is a vital step closer to knowledge people in pics and motion pictures. Strong articulations, small and hardly visible joints, occlusions, apparel, and lighting changes make it very difficult to perform estimate pose. Human Pose estimation is an important problem that needed to be study. It is used to detect human anatomical key points (e.g., shoulder, elbows, legs, wrist, etc.) in real time using less computational resources. There are many Artificial Intelligence models i.e, Posenet, OpenPose1 and MediaPipe8 for Real time Human Pose Estimation. Many experiments has performed to find out the best suitable model for Human Pose Estimation. Experiments stated that PoseNet is suitable to run on lightweight devices like browsers whereas OpenPose meant to run on GPU powered devices and is more accurate. On the other hand, MediaPipe is very fast, modular, reusable and highly efficient. Hence, our model uses the MediaPipe to perform its estimation.

A Framework for Evolution and Consciousness: Panpsychism Without Tears?
Authors: Edwards Jonathan C.W.
Published: December 2021

Giving an account of the relation between evolution and consciousness is painted as posing a dilemma between panpsychism, with minimal consciousness in every grain of matter, and radical emergence, with consciousness appearing as from nowhere in living structures. Panpsychism has been
seen as suffering from a combination problem and radical emergence as unjustified in physics. The underpinning of physics now lies in field theory, which may provide a way out on both sides. Only, and always, in a field theory account do influences at different points in space-time combine
in the same indivisible event. Radical emergence is also inherent to field theory. Moreover, by providing rich patterns of influence involving both discrete identities and quantitative values, field theory might provide a basis for sensed propositional meaning with subjects and predicates.
Ordered condensed matter within living tissue may support unusual emergent dynamic units uniquely suited to building representations of the world with sensed meaning. The evolution of consciousness may then be seen as a tractable biological problem centred on increasingly sophisticated ways
for external world dynamics to be mirrored by internal representations with semantic content, based in field relations within condensed matter with genetically encoded complex order.
Deep learning aplicado para la detección de hemorragias y tumores cerebrales
Authors: Hidalgo Barrientos Mauricio Fernando , Hayes Ortiz Bryan Isaac , Delgadillo Vera Ignacio , Goyo Escalona Manuel
Published: December 2021

Introdução: Um dos problemas que afeta a saúde no Chile refere-se às patologias cerebrais, à realização de exames e à longa espera pela obtenção dos resultados (atrasos no diagnóstico e tratamento). Atualmente, os exames são enviados ao exterior para serem processados e o tempo de espera jog contra o paciente. Dada a realidade, nosso documento propõe um modelo de deep learning para predição de imagens cerebrais que permite obter um diagnóstico prévio, mas não definitivo, em virtude de diminuir o tempo do processo e, se necessário, priorizar pacientes cuja vida estaria potencialmente em risco. Métodos: O desenvolvimento usou uma abordagem RAD iterativa e as imagens foram coletadas do Kaggle. Além disso, o conjunto de dados é redimensionado para normalizar o tamanho e geramos novas imagens usando “data augmentation”. As imagens foram processadas em redes convolucionais, investigando diferentes configurações da rede, seu otimizador e a função de ativação, até chegarmos a um modelo que consideramos razoável. Resultados: Com o modelo definitivo os resultados ultrapassam 80% de acertos nas previsões e descobrimos que separar patologias (hemorragias e tumores) foi fundamental para este resultado. Conclusões: alcançamos uma ferramenta de diagnóstico prévio, mas a pesquisa deve ser continuada em virtude do aumento da precisão. Uma próxima etapa é expandir o conjunto de dados com imagens de outras fontes e separar o modelo para analisar patologias de forma independente. Encorajamos mais investigação, uma vez que este tipo de apoio pode ajudar a salvar vidas.

Neste texto, apresentamos um relato de experiência a partir da escrita de cartas, proporcionado pelo projeto de extensão para formação de professores Cirandar: rodas de investigação na escola, promovido pela Universidade Federal do Rio Grande (FURG), na região de Bagé, no Rio Grande do Sul, durante o período de agosto de 2020 a abril de 2021. No relato, visamos mostrar alguns aspectos deste processo de autoformação, a partir de cartas recebidas por e-mail da coordenação do projeto, orientando a escrita das cartas dos participantes. Iniciando pela primeira carta, com a apresentação dos integrantes do grupo; a segunda carta, sobre os temas de interesse para estudo e discussões sobre os desafios da docência e da adaptação ao modo remoto de trabalhar; e na terceira carta, uma discussão teórica sobre aprendizagem ativa que finaliza com algumas considerações sobre as aprendizagens promovidas por esse processo formativo.  Destaca-se, nessa edição do Cirandar, o acolhimento por meio da liberdade de escrita sobre os sentimentos nesse período, a reflexão provocada pelos questionamentos feitos pelos pares de leitura e o espaço para pensarmos sobre nós mesmos e a profissão docente.
Reconceituando Língua e Discurso no referencial de Wenger sobre Comunidades de Práticas
Authors: Halu Regina Celia
Published: December 2021

Este artigo apresenta uma proposta de reconceitualização de linguagem e discurso no referencial de comunidades de prática (CP) de Lave e Wenger (LAVE; WENGER, 1991; WENGER, 1998). Wenger adota o conceito de discurso de Gee (1992), mas sem compreender discurso como prática social. Com relação à negociação de significados dentro de práticas sociais, a explicação se baseia nos processos de participação e reificação. Linguagem aparece em alguns dos exemplos de produtos derivados de tais processos, recebendo um tratamento limitado e, por vezes, incongruente. Objetivando adaptar o referencial de Wenger para a área de Linguística Aplicada e formação de professores, na presente proposta linguagem é conceitualizada como discurso, conforme discutido por Foucault (2000), apoiando-se também nas reflexões de Maturana (2001, 2005) sobre linguagem. Tal adaptação torna o referencial de CP mais específico para pesquisas na área de línguas e formação de professores, que explorem práticas discursivas.

Este artigo tem como objetivo discutir algumas das principais noções que orientam e organizam o componente Língua Portuguesa no Ensino Fundamental da Base Nacional Comum Curricular. No cerne da discussão, destacam-se as noções de texto e de letramento, ambas relacionadas ao debate atual acerca das fake news, conceito também discutido pelo documento e apresentado como importante fenômeno social a ser analisado em sala de aula. A reflexão se assenta em uma pesquisa bibliográfica, orientada por leituras e análises que permitem uma visão crítica sobre as questões em estudo. Na esteira das discussões, reconhecemos que as noções de texto, gênero discursivo e letramento adotadas pela Base Nacional Comum Curricular relacionam-se à perspectiva enunciativa-discursiva da linguagem, isto é, à ideia de linguagem como prática social. Desse modo, propomos que o ensino e a realização de atividades pedagógicas que visam desenvolver as competências e habilidades elencadas pelo documento, inclusive no que diz respeito às fake news, deverão guiar-se pelas implicações derivadas desses conceitos.

A espécie Urochloa brizantha cv. Marandu é uma das gramíneas mais utilizadas em todo país, para estas plantas persistirem em solos arenosos, a fertilização é necessária devido à sua menor fertilidade natural. A reposição periódica de nutrientes do solo é de grande importância. Para melhor eficiência da adubação nitrogenada, novas tecnologias surgiram no mercado. Objetivou-se avaliar o efeito da aplicação de doses e fontes de N sobre a produtividade das pastagens de capim-marandu para verificar a eficiência de utilização da adubação nitrogenada pela planta; maximizando o uso do fertilizante a fim de reduzir as perdas; diminuir os custos com adubação nitrogenada, ocasionando melhorias na produção de pastagens no Estado do Mato Grosso do Sul. O experimento foi conduzido de fevereiro a março de 2016 numa área estabelecida de Urochloa brizantha cv. Marandu. O delineamento experimental foi em blocos ao acaso com quatro repetições, em esquema fatorial 4x3+1. Os tratamentos consistiram na combinação de quatro fontes de nitrogênio (nitrato de amônia, ureia, ureia com polímero e ureia NPBT) e três doses (50, 100 e 150 kg ha-1 de N), acrescido um tratamento sem adubação nitrogenada (controle). Avaliaram-se produção de massa seca da parte aérea da pastagem, teor de proteína bruta e determinação da eficiência da adubação. Conclui-se que a aplicação de fontes nitrogenadas proporciona maior produtividade de MS, aumentam os tores de PB, respondendo de forma gradativa com o aumento das doses nitrogenadas na Urochloa brizantha cv. Marandu. As fontes ureia com polímero e NBPT obtiveram maiores respostas para produtividade em comparação a nitrato de amônio e ureia. Na primeira e segunda avaliação a fonte ureia com polímero e ureia com NBPT apresentaram maior eficiência agronômica quando comparada com a ureia e nitrato de amônio.

A partir do processamento mínimo notou-se um aumento no consumo de frutas e hortaliças devido à praticidade de serem prontas para o consumo. Sendo assim, o objetivo desta pesquisa foi à caracterização física, química, bioquímica e microbiológica da pitaya vermelha (Hylocereus costaricensis) minimamente processada armazenada sob refrigeração. As frutas foram obtidas de uma propriedade localizada na cidade de Marília/SP, em seguida transportadas para o Laboratório de Físico-Química da FATEC/Marília. As pitayas passaram pelas etapas do processamento mínimo e após foram armazenadas a 5°C durante 12 dias. Os parâmetros físicos e químicos foram avaliados a cada 3 dias durante 12 dias e os bioquímicos nos dias 0, 9 e 12, na polpa congelada em freezer a -80°C. As análises microbiológicas foram realizadas com 0 e 12 dias de armazenamento. Os valores de pH, não apresentaram diferenças estatísticas durante o período de armazenamento, já a acidez titulável (AT) e os sólidos solúveis (SS) demostraram variação estatística com o decorrer do armazenamento (p<0,05), verificando-se que os teores de SS aumentaram e AT diminuíram. Para os teores de vitamina C e pectinas totais e solúveis não foram verificadas diferenças estatísticas (p>0,05) ao longo do armazenamento. Em relação as análises microbiológicas, a pitaya minimamente processada se encontrou dentro dos limites estabelecidos pela legislação. As etapas do processamento mínimo foram conduzidas com boas práticas de fabricação baseando-se na ausência de micro-organismos obtidos ao longo do período de armazenamento. A vida útil da pitaya vermelha minimamente processada foi de 12 dias sob uma temperatura de 5°C.

Uma boa formação de pastagens começa pela qualidade da semente forrageira. O uso de sementes de baixa qualidade e a escolha indevida da forrageira influenciará diretamente na formação inicial do pasto. No entanto, as espécies forrageiras tropicais exibem algumas dificuldades, como a desuniformidade na maturação e dormência nas sementes, cujo aspectos como natureza, intensidade e persistência não estão totalmente esclarecidos. Além disso, a degrana natural das sementes é uma outra limitação à produção de sementes de espécies forrageiras tropicais, o que diminui a eficiência dos métodos de colheita e prolonga a emissão da inflorescência. Um dos principais problemas relacionados a comercialização de sementes forrageiras tropicais é a estacionalidade característica do mercado, a qual está intimamente associada à época de plantio de pastagens, que ocorre no período de chuvas. Outra dificuldade é ausência de informação legal sobre o uso alternativo para as sobras e descartes de sementes forrageiras quando não atendem os padrões mínimos de qualidade para comercialização.

O processo de micropropagação possibilita a maior rapidez regenerativa das plantas, facilitando a propagação mais rápida quando as tecnologias convencionais são difíceis. No entanto, a ocorrência de bons resultados na micropropagação depende da otimização de enumeras variáveis. Ao final, uma das principais dificuldades na micropropagação de plantas é a contaminação microbiana dos explantes in vitro, a qual afeta o desenvolvimento da planta pela competição dos nutrientes, ou exudando substâncias que acidificam o meio de cultura e ou liberando fitorreguladores. Um dos problemas enfrentados pelos laboratórios de cultura de tecidos vegetais é a contaminação microbiana e há grande dificuldade na identificação da fonte de inóculo e o seu controle. Os microrganismos encontrados na contaminação dos explantes provêm de uma vasta e diversificada escala de grupos ecológicos. Os endofíticos são organismos que em pelo menos uma fase do seu ciclo de vida, habitam o interior de tecidos da parte aérea de plantas assintomáticas, sendo denominados endófitos facultativos ou verdadeiros conforme o grau de interação dos mesmos com as plantas hospedeiras. Assim, o objetivo desta revisão foi explorar sobre os estudos de plantas in vitro associadas a microrganismos endofíticos e os efeitos dessa relação.

A perda de alimentos ocorre em nível mundial tendo seu maior índice no setor de frutas de hortaliças. Uma das tecnologias pós-colheita que são empregadas e reduzem essas perdas, são os revestimentos, podendo ser comestíveis ou não. Eles apresentam vantagens por serem de baixo custo e preservarem as características físicas, nutricionais e sensoriais de frutas e hortaliças. O presente trabalho teve como objetivo apresentar pesquisas sobre os diferentes tipos de revestimentos que tiveram sucesso na pós-colheita de frutas para conservação dos frutos e qualidade. A partir das pesquisas observadas, dependendo do tipo de material e do fruto, vários revestimentos apresentaram sucesso em reduzir a perda de água e consequentemente a massa do fruto, reduzir as trocas gasosas atrasando o processo de maturação, e também em análises microbiológicas tendo efeito sobre o desenvolvimento de microrganismos. Os atributos da qualidade como sabor, visual, textura, aparência também podem ser preservadas por um período maior de tempo. Conclui-se que essa tecnologia surge como uma opção para manter a qualidade e estender a vida útil dos produtos, preservando as características que são indispensáveis para os consumidores na hora da compra.
