Abstract: Objective: As isolates of Cryptococcus are frequently kept collection stocks in institutions, sometimes without proper characterization, we sought to determine the genotype profiles, protease and phospholipase activities “in vitro” and the susceptibility testing for azoles and amphotericin B. Methodology: 84 isolates from several regions of Brazil (40 samples from clinical origin and 44 isolates from environmental origin) were maintained at the microorganism’s bank of the Biomedical Science Institute (ICB-USP) of the São Paulo University, in São Paulo, Brazil. This isolates was submitted fungal strains determination, DNA extraction and purification, determination of genotype by URA5 gene RFLP of CGB-positive isolates, protease and phospholipase activity and susceptibility to antifungals. Results: Of six CGB positive isolates tested by RFLP-PCR, only four presented a genomic profile consistent C. gattii species (VGII), while two other were C. neoformans (VNI and VNIII), indicating the existence of canavanine-resistante C. neoformans isolates in the culture collections. The clinical isolates secreted higher levels of phospholipase and environmental isolates but no differences were observed for the protease levels. Almost all isolates were sensible to azoles and amphotericin B. Conclusion: We point out in this research the existence of C. neoformans strains resistant to canavanine and intrinsic characteristic of C. gatti. These results demonstrate the importance to perform a detailed characterization of isolates kept in culture collections.

Abstract: Among the numerous botanical species found in the Brazilian plant biome, Ximenia americana is widespread in the Northeast of Brazil, especially in the state of Ceará, where it is known as bush plum. Its bark, leaves and roots are used in popular medicine for the treatment of skin infections, hemorrhoids, stomach ulcers, gastric pain, among others. In this work, hexane and ethanolic extracts of X. americana seeds were subjected to silylation reactions followed by analysis of the silylated derivatives by gas chromatography-mass spectrometry (GC/MS). In the hexane extract, 18 substances were identified, where the most abundant and most important components were the Octadec-9-enoic (38.14%), (9Z,12Z)-Octadec-9,12-dienoic (18.83%), Ethanedioic (8.21%) and (Z,Z,Z)-9,12,15-Octadecatrienoic (7.22%) acids. From the ethanol extract 18 substances were also identified having D-Sucrose (29.36%), L-Sorbose (9.19%), syllo-Inositol (8.34%) and D-Glucose (7.45%) as the main components. In addition, the presence of a steroid in hexane extract and triterpenes in ethanol extract was recorded. The constituents were identified using chromatographic and spectrometric methods, especially gas chromatography-mass spectrometry. To our knowledge, this is the first study of this nature from the oil of the X. american seeds.

Abstract: Inflammatory Bowel Disease (IBD) and other auto-inflammatory disorders are conditions caused by chronic and persistent intestinal inflammation, which is mainly represented by Ulcerative Colitis (UC) or Crohn’s Disease (CD), both of which typically arise as chronic inflammation of the gastrointestinal mucosa. Doctor’s main focus for treating IBD is the decrease on inflammation processes when the disease is active and promotes the maintenance of inflammation at normal levels. However, to deal with these two parameters is not easy, because the drugs usually used are related to several side effects and they are not totally effective to reduce inflammation and to keep the remission. Authors agree that the therapy approach should include drugs, dietary intervention and use of alternative substances as probiotics. The standard treatment approach for patients with CD and UC is traditionally done with the use of anti-inflammatory agents, like corticosteroids, mesalamine, immunomodulators such as azathioprine and methotrexate, and biologic agents such as infliximab and others. Probiotics are known as viable micro-organisms (or live microorganisms or live microbial dietary supplements) that may promote beneficial physiologic or therapeutic properties when used correctly. The interest in the role of these substances in improving human health is the reason of several researches. They may be used to help the immune system, to control gastro-intestinal infections and to prevent several diseases. Prebiotics, symbiotics, and probiotics may be helpful as adjuvants in the treatment of IBD. Probiotics are normally well-tolerated and are associated with few side effects which are undoubtedly important in the treatment of any disease.

Abstract: The objective of this work was to evaluate the effect of the basal cut, leaf presence and the treament with a root suspension in the rooting of herbaceous minicuttings of yellow passion fruit. The experiment was realized in a greenhouse using minicuttings with 8 cm of lenght and two nodes, collected from yellow passion fruit seedlings. The longitudinal basal cut in the minicuttings was done until the basal node. The leaves were removed or a half of a single leaf was maintained in the apical node. The minicuttings were treated with a root suspension in water in three concentrations (0, 100 e 200 g L-1). After 58 days, the rooting percentage, the number of roots and the root dry matter produced per minicutting were determined. The entirely randomized experimental design was used in a factorial esqueme (2 x 2 x 3) with three replications. The propagation of the yellow passion fruit by herbaceous minicuttings was viable and the presence of the half of a single leaf in the apical node give a higher production of number and dry matter of roots. The basal cut was only a little favourable to the production of roots and the treatment with a root suspension did not present a benefit to the plant propagation. Este trabalho objetivou avaliar a influência do corte basal, da presen a da folha e do tratamento com suspens o de raízes no enraizamento de miniestacas herbáceas de maracujazeiro amarelo. O experimento foi conduzido em casa de vegeta o com miniestacas de 8 cm de comprimento e dois nós, obtidas de mudas de maracujazeiro. O corte longitudinal na base das estacas foi feito até o nó basal. Foram retiradas as folhas ou mantida a metade da folha do nó apical. As miniestacas foram tratadas com suspens o de raízes mais água nas concentra es de 0, 100 e 200 g L-1. Após 58 dias, determinou-se a porcentagem de estacas enraizadas, o número de raízes emitidas e a massa seca de raízes por estaca. O delineamento experimental utilizado foi o completamente casualizado em um esquema fatorial 2 x 2 x 3 com 3 repeti es. A propaga o do maracujazeiro amarelo por miniestacas herbáceas foi viável e a manuten o de meia folha no ápice da estaca permitiu a produ o de maior número e massa seca de raízes. O corte basal da miniestaca favoreceu pouco a emiss o de raízes e a técnica adotada de tratamento das miniestacas com a suspens o de raízes n o proporcionou benefícios à propaga o da planta.
