STORAGE OF Handroanthus umbellatus SEEDS

Seed storage under controlled environmental conditions represents one of the most important lines of research to be applied on short-lived forest species as Handroanthus. The present research aimed to identify the most suitable seed storage conditions and longevity behavior of Handroanthus umbellatus seeds subject to the following storage treatments: packaging permeable paper bags under a no-controlled laboratory temperature and humidity (control) and multiwall semipermeable bag at temperatures of -18 degrees C ,1 degrees C and 25 degrees C. Seeds were dried to 6.3% of water content. Stored seeds were evaluated every three months until 24 months for water content, germination percentage and vigor utilizing first counting test. Seeds of T. umbellata are orthodox, with low longevity under natural conditions, once they remain viable for less than 5 months. The best conditions of seed preservation of these species were obtained by storage at -18 degrees C in multiwall bags. Under these conditions physiological seed quality remains unchanged for a 24-month period.

Detecção de Salmonella Enteritidis em ovos de codornas japonesas submetidas a dietas com diferentes níveis de cálcio e fósforo

The eggs are pointed in several studies as the main cause of human salmonellosis. Have been identified that eggs are eaten raw or poorly processed are mainly responsible for outbreaks of human infection with Salmonella spp. Besides causing problems to public health, the presence of bacteria impedes or hinders the international food trade, as a sanitary barrier. Several factors predisposing to contamination of the internal contents of eggs for Salmonella spp., including the egg shell quality (shell quality), which is related to levels of calcium (Ca) and phosphorus (P) in the diet of quails . The experiment used eggs of Japanese quail under different diets containing two levels of Ca (2.0 and 3.5%) and two levels of available P (0.25 and 0.45%). Eggs of 120 japanese quails were divided into four treatments with three replicates. The experiment was divided into three production stages: initial, intermediate and final. Were assessed at each stage the presence of bacteria in internal and external content of experimentally contaminated eggs during periods of 0, 24, 96 and 168 hours after immersion in broth containing Salmonella Enteriditis. Salmonella Enteriditis was detected in the shell during all periods of storage, in decreasing amounts in all treatments. None of the treatments within the three production stages analyzed, we detected significant amounts of the bacteria inside the egg, in our experimental conditions. Therefore, the levels of Ca and P in the diets of quail do not determine higher or lower risks to public health represented by eggs

Effect of ultrasonic ecxitation on the ultimate tensili strength of glass ionomer cements after different water storage times

The application of ultrasound waves with a conventional dental ultrasonic scaler on glass ionomer cements surface accelerated initial setting reaction and improved the mechanical properties. Objective: This study evaluated the ultimate tensile strength of glass ionomer cements after ultrasonic excitation and different water storage times. Material and method: Twelve specimens of each material (Fuji IX GP, Ketac Molar Easymix and Vitremer) were prepared, and six of each received a 30-second ultrasound application during initial setting of the cements. After storage of the 24 hours or 30 days, the specimens were sectioned into stick to microtensile testing and the mean ultimate tensile strength values were submitted to Welch’s ANOVA and Tamhane’s test. Result: The results showed that the Vitremer presented the highest mean tensile strength. The chemically set Fuji IX GP presented significantly higher mean tensile strength after 30 days than after 24 hours of storage (p < 0.05). At 24 hours, the ultrasonically set Fuji IX GP presented significantly higher mean tensile strength than their counterparts set under standard conditions (p < 0.05). Conclusion: Treatment with ultrasound increased the tensile strength of Fuji IX GP in the early period of maturation.

Efficiency of cares over toothbrush storage to prevent contamination

This study evaluated the efficiency of a toothbrush holder to prevent contamination of toothbrushes used by preschool children. For that, the sample was composed by children 6 years old, enrolled in an educational and recreational center in Araraquara/SP, and divided into 3 groups: G1: same continuing routine storage toothbrushes, G2: children received only a new toothbrush holder for storage; G3: they received new toothbrushes holder for storage and solution of chlorhexidine digluconate to 0.12% to dabble in the toothbrush after use. After brushing their teeth, toothbrushes were collected for microbiological analysis. The data were analyzed using the distribution of frequencies. It was observed that, in general, higher prevalence of the microorganism in the toothbrushes was Streptococcus viridans (58.97%), followed by Estafilococcus (35.90%), the bacillus of air (28.21%) and Neisseria mucosa (5.13%). Evaluating frequency, it was noted that the contamination presented by Streptococcus is higher in G1 when compared to G2 and G3, while for Estafilococcus, the presence was more significant in G3. Thus, it was concluded that the use of new toothbrushes holder able to avoid direct contact between brushes and allow drying without smothering could be an excellent alternative to educational institutions that require the storage group.
