The effect of chlorhexidine on plaque index and mutans streptococci in orthodontic patients: A pilot study

Aim: The purpose of this study was to assess chlorhexidine effects on plaque index and salivary levels of mutans streptococci (MS) when used as the immersion solution for removable orthodontic appliances and added to their acrylic resin composition. Methods: Forty-five patients (6 to 12 years old) were randomly assigned into three groups with 15 patients each. Group I (control)—without orthodontic appliances disinfection; Group II—removable orthodontic appliances which had been immersed in 0.12% chlorhexidine digluconate overnight (8 hours), and Group III—orthodontic appliances in which 0.12% chlorhexidine digluconate solution had been incorporated into their resin composition. Saliva was collected for quantification of MS and evaluation of plaque index was performed before and after installation of orthodontic appliance at 0, 2, 4, 6, 8, and 10 weeks. Data were analyzed by using analysis of variance. Results: Number of MS colonies in saliva and plaque index showed no statistically differences among groups at the different periods (p > 0.05). Conclusions: It could be concluded that chlorhexidine incorporation into the acrylic resin of removable orthodontic appliances at 0.12% concentration and immersion of the appliance into 0.12% chlorhexidine solution were not effective in reducing plaque index and the number of MS in saliva.

Obtenção de massa de mandioca com adição de maltodextrina de amido de milho waxy

This study aimed to the development of cassava mashed with added maltodextrin of waxy maize starch as an alternative to the semi-ready product. The experimental design was completely randomized using blocks in 4x7 factorial, with three replications. The treatments were the combination of maltodextrin concentrations added in the cassava mass (0, 5, 10 and 15% on dry weight) with storage time (0, 2, 4, 6, 8, 10 and 12 days after preparation) and two condition (environment and refrigerated temperature). The variety chosen to the processing was the IAC 576-70. The data were subjected to variance analysis. The means were compared by Tukey test at 5%. The content of maltodextrin from waxy maize starch to 15% was effective in controlling the increase of texture. The mass of cassava with the addition of maltodextrin showed to be product of easy preparation, showin IAC 576-70g viability to be produced in industrial scale.

Avaliação da cultura do rabanete ao longo do ciclo submetido em diferentes níveis de salinidade

The increased volume of water, facing food production in recent years has meant that research should seek ways to optimize and / or reuse water with salinity levels. This the aim of the study was to analyze the influence of salinity irrigating the culture of radish. In the culture of radish was subjected to irrigation water salinity 2, 4, 6, 8 and 10 dsm-1 , and the analysis conducted over time. The experiment was conducted at UNESP, Faculty of Agricultural Sciences, Lageado Experiment Station, located in Botucatu/SP, in a greenhouse. The results indicate that salinity causes reduction in fresh and dry weight of the bulb, and has effect in the ratings over the cycle.

Teste de condutividade elétrica para avaliação da qualidade fisiológica de sementes de gergelim (Sesanun indicum L.)

Two experiments were conducted in order to study the effects of seed number, temperature and time of soaking sesame seeds on the results of the electrical conductivity test for physiological quality of seeds. In the experiment I evaluated the electrical conductivity varying the number of seeds (25, 50 and 100) and temperature (20, 25 and 30° C) in experiment II is different soaking periods (2, 4, 6, 8, 12, 16, 20 and 24 h). The tests were performed with three cultivars (cv. Trebol, cv. Cnpa G4 e cv. Comum). The treatments in factorial 3x3x3 and 3x8 in experiments I and II, respectively. The experimental design was completely randomized, with four replications. Means were compared by Tukey test at 5% probability. The characterization of cultivars held through the germination and vigor tests (physical, physiological and biochemical), which rated the Trebol cultivar seeds with better physiological then the Cnpa G4 and Comum. The electrical conductivity test was conducted with four sub-samples of 25 pure seeds soaked in 75 mL of deionized water at 25° C, to separate the lots from 2 hours of soaking, being feasible to evaluate the quality sesame seeds.

Glutamate-induced obesity leads to decreased sperm reserves and acceleration of transit time in the epididymis of adult male rats

Background: Given the established fact that obesity interferes with male reproductive functions, the present study aimed to evaluate sperm production in the testis and storage in the epididymis in a glutamate-induced model of obesity. Methods: Male rats were treated neonatally with monosodium glutamate (MSG) at doses of 4 mg/kg subcutaneously, or with saline solution (control group), on postnatal days 2, 4, 6, 8 and 10. On day 120, obesity was confirmed by the Lee index in all MSG-treated rats. After this, all animals from the two experimental groups were anesthetized and killed to evaluate body and reproductive organ weights, sperm parameters, plasma hormone levels (FSH, LH and testosterone), testicular and epididymal histo-morphometry and histopathology. Results: Significant reductions in absolute and relative weights of testis, epididymis, prostate and seminal vesicle were noted in MSG-treated animals. In these same animals plasma testosterone and follicle-stimulating hormone (FSH) concentrations were decreased, as well as sperm counts in the testis and epididymis and seminiferous epithelium height and tubular diameter. The sperm transit time was accelerated in obese rats. However, the number of Sertoli cells per seminiferous tubule and stereological findings on the epididymis were not markedly changed by obesity. Conclusions: Neonatal MSG-administered model of obesity lowers sperm production and leads to a reduction in sperm storage in the epididymis of adult male rats. The acceleration of sperm transit time can have implications for the sperm quality of these rats.

Seasons of desiccant application in the soybean crop: water content and productivity

The herbicides glyphosate and paraquat have been used by Brazilian soybean producers to obtain crop desiccation and to anticipate and uniformity at harvest. However, improper use of herbicides can to occasion problems in agronomic and physiologic characteristics of crop. This study aimed to evaluate the use of the glyphosate and paraquat herbicides as a desiccant for growing soybeans. The experiment was conducted in 2005/06 crop year, in an experimental design of randomized blocks with four replications. Treatments were arranged in two factorial design, 3x3x5x2 and 3x2x5x2: two desiccants (glyphosate and paraquat) and control (without drying), three and two growth stages (R6, R7 and R8) and (R7 and R8) for varieties MSOY 6101 of superprecocious cycle, and MG / BR 46 (Conquista) of precocious cycle, respectively, five sampling times (2, 4, 6, 8 and 10 days after application) and two positions in the plants on the ground assessment (apex and base). Was evaluated for seed Production, mass and water content of 100 seeds. Desiccants tested were effective in reducing the water content of seeds, without affecting productivity and mass of 100 seeds.
