Controle em pós-colheita de Penicillium digitatum em laranja-pera com microrganismos e tratamento térmico

The consumer market demands food without pesticide residues. Therefore, this study focused on evaluating the control of green mold in Pera orange trees with biocontrol agents (Bacillus subtilis, Bacillus licheniformis and Bacillus subtilis (QST 713)), associated or not with heat treatment. The fruit was obtained in packinghouse before processing, being washed and disinfected with the use of Sodium Hypochlorite. Fruits submitted to these treatments were stored from 11 to 28 days at temperature of 10 °C and RH 90%±5 or for eight days at 20 °C and 90%±5. In general, the heat treatment reduced the disease severity determine by the area under the disease progress curve in the fruit and the incidence of natural postharvest disease in Pera oranges. On the other hand, biocontrol agents did not control the disease, showing that the organisms tested did not present curative activity against the green mold.

Effect finishing and polishing procedures on the surface roughness of IPS Empress 2 ceramic

Objective. To evaluate the surface roughness of IPS Empress 2 ceramic when treated with different finishing/polishing protocols. Materials and methods. Sixteen specimens of IPS Empress 2 ceramic were made from wax patterns obtained using a stainless steel split mold. The specimens were glazed (Stage 0-S0, control) and divided into two groups. The specimens in Group 1 (G1) were finished/polished with a KG Sorensen diamond point (S1), followed by KG Sorensen siliconized points (S2) and final polishing with diamond polish paste (S3). In Group 2 (G2), the specimens were finished/polished using a Shofu diamond point (S1), as well as Shofu siliconized points (S2) and final polishing was performed using Porcelize paste (S3). After glazing (S0) and following each polishing procedure (S1, S2 or S3), the surface roughness was measured using TALYSURF Series 2. The average surface roughness results were analyzed using ANOVA followed by Tukey post-hoc tests (α = 0.01) Results. All of the polishing procedures yielded higher surface roughness values when compared to the control group (S0). S3 yielded lower surface roughness values when compared to S1 and S2. Conclusions. The proposed treatments negatively affected the surface roughness of the glazed IPS Empress 2 ceramic. © 2013 Informa Healthcare.

Anatomia topográfica e comportamento arterial do pâncreas em cágados Trachemys scripta elegans (wied, 1838)

The turtle Trachemys scripta elegans popularly known as American tiger water are native regions winged Florida and Mississippi, in the United States. We used twenty (20) turtles (Trachemys scripta elegans), adult males and females, which were euthanized under Resolution 714 of June 20, 2002 the Federal Council of Veterinary Medicine (CFMV). After euthanasia were identified aortas right and left to the injection of Neoprene latex 450, stained with specific pigment. To obtain the vinyl mold aorta was injected through the right and left vinyl acetate, followed by corrosion in sulfuric acid. It was observed that the pancreas is closely related to the liver, gizzard, gall bladder, and duodenum. His face cranial this distal region of the pylorus, while its caudal along the cranial region of the duodenum. Anatomically, the pancreas is an elongated body structure featuring a lightly lobed. As to the pancreas arterial vasculature is flushed in its transverse plane of two arteries arising from the celiac artery, and each antimere two pancreaticoduodenal artery in the cranial region, close to the pylorus by the pancreaticoduodenal artery flow in the caudal portion along the duodenum.

Avaliação de microrganismos antagônicos, Saccharomyces cerevisiae e Bacillus subtilis para o controle de Penicillium Digitatum

Citrus fruits are affected by diverse diseases, mainly the fungal infections, which affect productivity and quality, especially when it targets the market of fresh fruit. Among the fungal diseases that occur in postharvest, there is the green mold caused by Penicillium digitatum. The control measures are based mainly in the treatment of fruits with different combinations of fungicides in packing-house. Due to restrictions on the presence of residues of fungicides in citrus fruits and the increasing development of resistant strains of pathogens to the fungicide used, it is necessary to search for control alternatives such as biological control. Therefore, this study aimed to: (i) verify the antagonistic effect of biological control agents (BCA), being 13 isolates of Bacillus subtilis and 06 isolates of Saccharomyces cerevisiae against P. digitatum, (ii) study in vitro interactions between pathogen and BCA (iii) determine the effect of integration of antagonists with sodium bicarbonate and carnauba wax in the control of green mold. The results showed that the majority of the isolates, and all yeast isolates inhibited the mycelial growth of the phytopathogen. Only one isolate of B. subtilis (ACB-84) was able to inhibit the germination of P. digitatum (72% of inhibition), whereas ACB-K1 and ACB-CR1 (S. cerevisiae) were the most effective with inhibition from 78 and 85.7% respectively. The addition of sucrose (0.5%) favored the inhibition of conidia germination by the yeast isolates. The results from the in vivo control showed the viability of S. cerevisiae ACB-K1 and ACB-CR1 to control P. digitatum in 'Tahiti' lime fruits and orange 'Hamlin' fruits, respectively. The combination of sodium bicarbonate and biocontrol agents did not result in improvements in the curative control of the green mold. Carnauba wax (18% of TSS) favored the antagonistic activity of S. cerevisiae, and this effect depended on the variety of fruits in the study and of the yeast isolate used for the biocontrol.

Degree of conversion and hardness of two different systems of the vitrebond™ glass ionomer cement light cured with blue LED

This study investigated the physicochemical properties of the new formulation of the glass ionomer cements through hardness test and degree of conversion by infrared spectroscopy (FTIR). Forty specimens (n = 40) were made in a metallic mold (4 mm diameter × 2 mm thickness) with two resin-modified glass ionomer cements, Vitrebond™ and Vitrebond™ Plus (3M/ ESPE). Each specimen was light cured with blue LED with power density of 500 mW/cm2during 30 s. Immediately after light curing, 24h, 48h and 7 days the hardness and degree of conversion was determined. The Vickers hardness was performed by the MMT-3 microhardness tester using load of 50 gm force for 30 seconds. For degree of conversion, the specimens were pulverized, pressed with KBr and analyzed with FT-IR (Nexus 470). The statistical analysis of the data by ANOVA showed that the Vitrebond™ and Vitrebond™ Plus were no difference significant between the same storage times (p > 0.05). For degree of conversion, the Vitrebond™ and Vitrebond™ Plus were statistically different in all storage times after light curing. The Vitrebond™ showed higher values than Vitrebond™ Plus (p < 0.05). The performance of Vitrebond™ had greater results for degree of conversion than Vitrebond™ Plus. The correlation between hardness and degree of conversion was no evidence in this study.
