25. Physiological and biochemical changes during desiccation tolerance loss in millet (Pennisetum glaucum L.) seeds
ABSTRACT. The aim of this study was to evaluate the physiological and biochemical changes related to desiccation tolerance loss in millet seeds. The studied points of the germination process were determined according to the seed imbibition curve of the millet hybrid ADRF6010: control (0h), 3h of imbibition, 1 and 3 mm radicle. The seeds were dried on silica

26. Effect of Short-Term Inhalation of The Herbicide 2,4D on Cardiac Remodeling: Morphological Aspects
Abstract Background: Brazil is the worldwide leader in the long-term use of pesticides and herbicides. This compromises the health of handlers by causing harmful neurological, respiratory, and cardiovascular changes. The herbicide 2.4D has been shown to cause cardiac overload with subsequent pathological remodeling. Objective: To analyze the cardiac morpho

27. Tomato seed image analysis during the maturation
Resumo: O potencial fisiológico das sementes está diretamente relacionado à normalidade do processo de formação delas, sob ponto de vista morfológico, estrutural e funcional. Deste modo, o objetivo deste trabalho foi avaliar a morfologia interna de sementes de tomate, híbrido BRS Nagai, em diferentes estádios de maturação, por meio da análise de i

28. Analysis of biodeterioration wood estate: use different techniques to obtain images
ABSTRACT This study was based on the current status of locomotive turntable of Provincial Railway Station in La Plata. It was inaugurated in 1910 and it was declared as architectural heritage in 2006. The locomotive turntable is 200 meters from this station and it is a structure that consists in wooden slats of Schinopsis sp. into metal framework. Currently,

29. AVALIAÇÃO DA QUALIDADE FISIOLÓGICA DE SEMENTES DE Moringa oleifera Lam.
RESUMO Os principais testes que avaliam a qualidade de sementes são destrutivos e exigem um tempo relativamente longo para serem concluídos. A análise de imagens de sementes por meio de raios X representa uma alternativa para este setor, sendo uma técnica reproduzível e rápida, permite maior agilidade e autonomia nas atividades dos sistemas de produç�

30. Modelos para predição da área foliar individual de leguminosas forrageiras
RESUMO A área foliar é uma variável essencial para a quantificação de outras importantes características foliares em estudos fisiológicos de plantas, como taxa fotossintética e teor de fósforo, normalizados por área. Essa é uma das razões para a necessidade de métodos rápidos e precisos para estimar a área foliar. O objetivo deste trabalho foi

31. Peculiar anatomical traits, high durability, and potential ornamental use of Cyclanthaceae as fresh foliage
ABSTRACT Wild plant species with potential for use as ornamental green foliage are often reported. Nevertheless, there are few studies evaluating morphological and anatomical aspects associated with this use. Preliminary trials suggest that the species of Sphaeradenia (Sander ex Mast.) Harling, a Cyclantaceae that occurs from Costa Rica to Peru, is suitable

32. Swingle citrumelo seed vigor and storability associated with fruit maturity classes based on RGB parameters
ABSTRACT: Citrus seeds normally have low storability. Identifying an optimal fruit harvest time for production of high vigor seeds is important for nurseries; however, identifying this stage for Swingle citrumelo fruits has been based only on visual color examination, and research related to this parameter has been inconsistent. The main objective of this st

33. Avaliação radiográfica de 1000 retentores intrarradiculares metálicos fundidos no Estado de Sergipe
Resumo Introdução Dentes com ampla destruição coronária e tratados endodonticamente necessitam de retentores intrarradiculares para viabilizar a restauração protética. Apesar do crescente uso de pinos intrarradiculares pré-fabricados, os retentores intrarradiculares metálicos fundidos ainda são muito utilizados. A qualidade desses é importante p

34. Different engagement of TLR2 and TLR4 in Porphyromonas gingivalis vs. ligature-induced periodontal bone loss
Abstract This study was conducted to investigate the roles of different Toll-like receptor (TLR) signaling in Porphyromonas gingivalis (P. gingivalis)-induced and ligature-induced experimental periodontal bone resorption in mice. Wild-type (WT), TLR2 knockout (KO), TLR4KO, and TLR2&4 KO mice with C57/BL6 background were divided into three groups: control, P.

35. DETERMINAÇÃO DE FOSFATO EM REFRIGERANTES UTILIZANDO UM SCANNER DE MESA E ANÁLISE AUTOMATIZADA DE DADOS: UM EXEMPLO DIDÁTICO PARA ENSINO DE QUÍMICA
We propose here the quantification of the phosphorus content in cola drinks by molybdenum blue method. Molybdenum blue method was carried out in the wells of a microplate, where method miniaturization represents reduction in reagents required, improved safety, reduced waste stream, and increased sample throughput. The phosphate concentration was determinate

36. Anti-inflammatory and healing action of oral gel containing borneol monoterpene in chemotherapy-induced mucositis in rats ( Rattus norvegicus )
ABSTRACT The aim of this study was to investigate the effect of gels containing the monoterpene borneol in induced oral mucositis using an animal model. Gels were prepared with borneol at 1.2% and 2.4% (w/w). Oral mucositis was induced by administration of three doses of 5-fluorouracil (30 mg/kg, i.p.) and injury with acetic acid (50%, v/v) soaked in filter
