To minimize problems related to the occurrence of cyanobacteria in water for human consumption there is need to investigate alternative treatment techniques with emphasis on biofilms with the potential degradation of microcystins (MC). This study aimed to evaluate the potential degradation of MC by bacteria Sphingosinicella microcystinivorans B9, different strains of yeast and probiotic bacteria. The test was carried out with the extract obtained from strain Microcystis sp. In the tests biomass and cultures of microorganisms were used and the treatments were maintained at 27°C with 100 rpm. Samples for analysis of MC and for counting the microorganisms were collected at 0 and 96 hours. The bacterium B9 presented the highest potential of degradation of MC reaching 98% after 96 hours.

The authors present the surgical reconstruction after excision of two synchronous adjacent basal cell carcinomas in the left infraclavicular region, using the Zetaplasty transposition flap technique. Being versatile and simple to perform, Zetaplasty was proven a useful solution for the reconstruction of double defects within a single procedure.

This experiment aimed to evaluate two types of harvest combines, the radial flow and axial flow rotary, regarding the physical and physiological seed quality of BRS 184 and BRS 133 soybeans cultivars, harvested in two periods of the day, at 10 a.m. and 6 p.m. The conventional combine worked moving at 5.0 km h-1, cylinder speed at 750 rotations per minute (rpm). The axial rotary combine worked moving at 8.0 km h, rotorspeed at 650 rpm. The germination test, vigour test, tetrazolium, mechanical (hypochlorite) damage, field and laboratory humidity test, broken seeds test and purity test were used to evaluate the physical and physiological quality of the seeds. The experiment performed at 6 pm, with a humidity level inferior to 12%, presented greater mechanical damages in BRS 184 seeds. The axial flow rotary harvest presented better seed physiological quality for BRS 184 cultivar, less percentage of broken seeds and greater purity for both cultivars, comparatively to the results observed for the radial flow rotary harvest.

Introduction. The neurogenic detrusor overactivity (DO) is an usual bladder disorder in subjects with multiple Sclerosis (MS) showing urinary incontinence, Urge (Ur) in 83% of cases. The standard treatment is pharmacological with well established evidence, contrary physiotherapy. Objective. to discuss the physiotherapeutic procedures in DO due to MS. Method. A review was conducted by searching the databases Cochrane Library, Ibecs, Lilacs, Medline, PEDro, and Scielo using the keywords: acupuncture, neurogenic bladder, biofeedback, bladder dysfunction, electroacupuncture, electro-stimulation, multiple sclerosis, physical exercises, Kegel exercises, physiotherapy, detrusor overactivity, urinary incontinence, pelvic floor rehabilitation, behavioral therapy and physical training, and urge incontinence. Results. There were found 26 articles and selected 10 with procedures indicated due to a statistical correlation with improvement of symptoms of DO and Ur (p ≤ 0.05). Among the articles, 6 demonstrated the application as unique way: myofascial therapy, Kegel exercises and electrical stimulation. The remaining combined Kegel exercises, electrical stimulation, electromyographic biofeedback, and orientations. Conclusion. None of physiotherapeutic procedures was seen as essential in the management of DO/ Ur in subjects with MS and it was observed that the combined approach procedures showed the levels of best evidence in this disorder.

The aim of this study was to evaluate the microencapsulation of pequi pulp by spray drying. A central composite rotational design was used in order to evaluate the effect of the independent variables: inlet air temperature, surfactant concentration and modified starch concentration. The dependent variables were assumed as yield of the process and the product features microencapsulated. A selection of the best process condition was performed to obtain the best condition of a product with the highest vitamin C and carotenoids content. Powders showed moisture content below 2%. The experimental values of hygroscopicity, yield, water activity, total carotenoids and vitamin C powders ranged from 7.96 to 10.67 g of adsorbed water/100g of solids, 24.34 to 49.80%, 0.13 to 0.30, 145.78 to 292.11 mg of ascorbic acid/g of pequi solids and 15.51 to 123.42 mg of carotenoids/g of pequi solids, respectively. The inlet air temperature 140°C, the surfactant concentration of 2.5% and the modified starch concentration of 22.5% was recommended as the selected condition. By the scanning electron microscopy, it was observed that most of the particles had spherical shape and smooth surface.
