Abstract: the objective of this work was to evaluate the morphophysiological responses of shoot apex of diploid musa acuminata subjected to in vitro polyploidization. the antimytotic agents colchicine (0, 1.25, 2.5, 3.75, and 5 mmol l-1) and oryzaline (0, 15, 22.5, and 30 μmol l-1), and two polyploidization periods were evaluated: 24 and 48 hours for colchicine, and 3 and 7 days for oryzaline. the application of colchicine significantly reduced the survival and the average number of shoots. oryzaline had a slightly negative effect on shoot apex survival and positively influenced the average number of shoots per explant. high mortality and accentuated oxidation of treated and regenerated explants were observed with both antimytotics. however, the morphogenetic capacity of the explants was reestablished after successive sub-cultivations in fresh media, and the produced shoots were elongated/rooted and acclimatized successfully. colchicine, at 1.25 and 3.75 mmol l-1 concentrations, and oryzaline represent a viable and practical approach for banana breeding programs. the morphophysiological effects observed in vitro are important to define strategies for induction of polyploidy in banana plants.

Abstract: Introduction: Lack of information continues to lead the professionals of various areas to contribute to environment degradation, and Dentistry is a potential source of contamination through chemical residues resulting from radiographic procedures. Objective: To evaluate the management of residues resulting from radiographic processing in dental radiology clinics and dental offices in S o Luís – MA, Brazil. Material and methods: A semi-structured questionnaire was prepared with the aim of characterizing the behavior of professionals and their procedures for discarding the processing solutions (developer, fixer, and water) and radiographic packing materials. A sample of 100 individuals represented 7.8% of the total number of 1,281 dentists in the city of S o Luís. Results: A total of 92% of the participants believed that radiographic effluents could cause damage to the environment. Concerning to the fixer discarding, 43% affirmed that they threw the solution directly through the sink, 36% diluted the fixer in water and threw it into the sink, 14% used a specialized company to discard it and 7% used other means. The developer was discarded as follows: 42% threw it down the sink, 36% diluted it in water before throwing it into the sink, 13% used a specialized company to discard it and 9% used other ways. Considering to the discarding of the packing of the radiographic films, 51% threw them into the trash and 49% used a specialized disposal company. Conclusion: Large portions of dentists do not discard radiographic processing residues and films correctly.

Abstract: Enteroaggregative (EAEC) and atypical enteropathogenic (EPEC) Escherichia coli are important bacterial etiologic agents causing diarrhea among children. The aim of the present study was to examine the impact of virulence factors predisposes to diarrhea. In this study some virulence properties were examined on 11 EAEC and 8 EPEC strains identified by Polymerase Chain Reaction (PCR), isolated from stool samples of children were analyzed genotypically and phenoltypically for the prevalence of virulence factors. The most frequently detected factor was resistance to serum (94%), followed by curli fimbriae (78%), biofilm production (73%), and gene coding for Extended-Spectrum Beta-Lactamase (ESBL) (68%). EPEC isolates showed at least three of the evaluated properties, while EAEC isolates showed at least two. The prevalence of these virulence factors between the two strains showed no statistical difference. This study showed the heterogeneity of the virulence profile of the isolates of EAEC and atypical EPEC strains and suggests that this diversity may influence in the disease severity.
