Gengivite Plasmocitária induzida por uso de pimenta

The aim of this case report is present a case in which the patient had plasma cell gingivitis induced by consumption of pepper. Patient A.M.S., male, 23 years, presented himself at the Clinic of Periodontology, complaining of severe pain, bleeding gums and tooth mobility. Interview was conducted not observing anything relevant. In oral evaluation, we observed in the anterior swollen gums, bleeding, suppuration and great touch, and tooth mobility. Being an aggressive framework in relation to patient age, we performed the following laboratory tests: complete blood count, blood sugar, and coagulation, and biopsy in the anterior inferior, because a diagnosis of lymphoma. At the end of antibiotic therapy, a significant improvement of clinical symptoms, pain relief, less swollen gums and reduce the suppuration and mobility. Laboratory tests showed no change. Fifteen days later, the patient returned with worsening of clinical status. The pathological diagnosis was plasma cell gingivitis and then performed a new history by placing greater emphasis on dietary habits, and the patient reported consumption of pepper in their meals, and relate this to clinical presentation. After elimination of pepper diet the patient showed remission of clinical data.

Avaliação sensorial e influência do tratamento térmico no teor de ácido ascórbico de sorvete de pimenta

In this work were prepared with three ice cream added peppers of different varieties: Capsicum baccatum, Capsicum annuum and Capsicum frutescens. The peppers were first pasteurized and evaluated in relation to the effect of heat treatment on the ascorbic acid content. Results showed that the Capsicum annuum showed higher ascorbic acid content, but the heat treatment resulted in greater loss of biocompounds. The higher retention of ascorbic acid was observed with Capsicum frutescens, which presented lower content of biocompound, but near of the pepper Capsicum annuum. The follow attributes was performed to evaluate the acceptance of ice cream through the sensory attributes: color, aroma, flavor and texture. Analysis of variance showed no significant difference between ice cream formulations at the 5% level of significance with regard to color, aroma and texture. Regarding taste, the samples differed significantly, at 5% significance, and the most preferred was the ice cream made with pepper Capsicum frutescens.

Desenvolvimento e avaliação físico-química, sensorial e da estabilidade de ácido ascórbico de doce de leite com pimenta

The dulce de leche or milk candy is a food widely consumed in Brazil, which shows typical characteristics of taste, color, flavor and texture. The lady-finger red pepper is regularly present on the Brazilian people table as this product contains a pungent flavor favoring various spices; and it is also rich in ascorbic acid (vitamin C) which is an excellent antioxidant. This study aimed at developing a dulce de leche containing lady-finger red pepper, and to determine the composition of the product. Also, the ascorbic acid contents were quantified in products stored for different periods (0, 30 and 60 days). The product acceptance by consumers on the sensory characteristics was evaluated by means of hedonic scale for color, aroma, flavor and texture attributes. The composition of the product was in accordance with the legislation in force, and the ascorbic acid contents were practically stable during the storage, and the sensory analyses indicated that the red pepper-containing dulce de leche was well accepted.

Vibração de plantas de pimenta Malagueta para produção de frutos e sementes em ambiente protegido

This study aimed to verify the effect of vibration of plants in the production of fruits and seeds and in the physiological quality of the seeds of the “Malagueta” pepper in a protected cultivated area with open and closed sides. The experiment was conducted at the Experimental Farm of the School of Agronomic Sciences of Universidade Estadual Paulista (FCA/UNESP), located in the city of São Manuel (SP). Two treatments were carried out, which consisted of plants that did and did not undergo vibration. Plants were vibrated manually by swinging the wire attached to the supporting bamboo for about 5 seconds, twice a day for 11 weeks. The design was a randomized block with six repetitions. The same experiment was conducted in two protected environments, with and without anti-aphids screens on the sides, cultivated in the same season. For the comparison of environments, a combined analysis was performed considering each environment as a separate experiment. The characteristics evaluated were: weight and number of fruits per plant; weight, diameter and length of fruit; weight and amount of seeds per fruit; and plant height. For the analysis of seed quality, the characteristics evaluated were: germination percentage; first count of germination; dry matter of seedlings; seedling emergence in substrate; and seedling emergence speed index. Regardless of the environment, vibration affects the physiological quality of seeds. The presence of pollinator insects benefited the production and quality of “Malagueta” pepper seeds and increases the fruit weight.

Comportamento higroscópico de partes aéreas de pimenta-de-macaco (Piper aduncum L.)

Isotermas de dessorção de pimenta-de-macaco foram determinadas pelo método gravimétrico estático nas temperaturas de 35, 45 e 55 ºC, com umidade relativa variando de 5,5-81%. Três modelos matemáticos foram aplicados para analisar os dados experimentais. O modelo de GAB modificado apresentou o melhor ajuste aos dados experimentais. O calor isostérico e a entropia diferencial foram determinados pela aplicação das equações de Clausius-Clapeyron e Gibbs-Helmholtz, respectivamente. O calor isostérico e a entropia da isoterma de dessorção apresentaram comportamento similar. A teoria da compensação entalpia-entropia foi aplicada às isotermas indicando que o mecanismo de dessorção de umidade das partes aéreas de pimenta-de-macaco é controlado pela entalpia.

Use of the checkerboard DNA-DNA hybridization technique for bacteria detection in Aedes aegypti (Diptera:Culicidae) (L.)

Abstract Background Bacteria associated with insects can have a substantial impact on the biology and life cycle of their host. The checkerboard DNA-DNA hybridization technique is a semi-quantitative technique that has been previously employed in odontology to detect and quantify a variety of bacterial species in dental samples. Here we tested the applicability of the checkerboard DNA-DNA hybridization technique to detect the presence of Aedes aegypti-associated bacterial species in larvae, pupae and adults of A. aegypti. Findings Using the checkerboard DNA-DNA hybridization technique we could detect and estimate the number of four bacterial species in total DNA samples extracted from A. aegypti single whole individuals and midguts. A. aegypti associated bacterial species were also detected in the midgut of four other insect species, Lutzomyia longipalpis, Drosophila melanogaster, Bradysia hygida and Apis mellifera. Conclusions Our results demonstrate that the checkerboard DNA-DNA hybridization technique can be employed to study the microbiota composition of mosquitoes. The method has the sensitivity to detect bacteria in single individuals, as well as in a single organ, and therefore can be employed to evaluate the differences in bacterial counts amongst individuals in a given mosquito population. We suggest that the checkerboard DNA-DNA hybridization technique is a straightforward technique that can be widely used for the characterization of the microbiota in mosquito populations.
