Abstract: the aim of this work was to isolate native wood white-rot fungi from fungal fruit-bodies and eucalyptus wood fragments from different regions of brazil and to test their potential for degrading dead stumps and roots in eucalyptus plantings after harvest. fungi isolates were obtained in a culture medium composed by eucalyptus sawdust and agar. among 292 isolates submitted to the banvedamm test, 144 were classified as phenoloxidases producing isolates. among nine c/n ratios tested, it was observed a tendency of occurring larger chip decay in the c/n ratios equal to 60 : 1, 200 : 1 and 300 : 1. two decay assays were performed in wood chips of eucalyptus saligna using the c/n ratio 60 : 1 in order to verify which isolates were able to cause larger reduction of dry matter. in the first assay, which was evaluated at 90 days of incubation, seven isolates that stood out in relation to trametes versicolor were selected. the second assay evaluated the capacity of 46 isolates in promoting decay. the isolates selected in the first assay were among the 11 most efficient in the second assay. based on dna analysis, six isolates were identified as pycnoporus sanguineus (3 isolates), peniophora sp., pestalotiopsis sp. e ganoderma sp.

Natural Science (NS) , 2016, DOI: 10.4236/ns.2016.83019
Abstract: Brazil is the largest producer of sugarcane and its derivatives in the world, and one of the largest consumers of sugarcane derivatives. Sugar places a position of great prominence in Brazilian feed, either by direct consumption or as a component of industrialized products, from increasing consumption in the country. Sugar samples taken from local market were analyzed as the quality of table sugar consumed in the state of Sao Paulo (Brazil). The analysis of the parameters and basic attributes of characterization of sugar was according to the methodology developed by ICUMSA (2005; 2011) and ICUMSA modified by Copersucar (2002). Samples of sugar from this region showed that medium-low quality. It can be observed in fundamental aspects such as purity and insoluble residues, which were below the standard. In addition, it should be noted the difficulty of obtaining information about the limit values for each attribute, by virtue of Legislation not be assertive to the product and, also, the scientific studies have not been unified to present the specifics for each type of sugar.

Abstract: Objective: To report attention changes in a sample of adolescents victims of domestic violence and discuss how this change may be related to an addictive and complex cycle of victimization and abuse. Methods: 78 adolescents went through psychiatric and neuropsychological evaluation. The Kiddie-Sads-Present and Lifetime Version and the Brazilian version of the Childhood Trauma Questionaire (CTQ) were applied. The neuropsychological assessment was conducted by trained professionals using the Wechsler Children’s Global Assessment Scale, 3rd edition-WlSC III. The sample was divided into 3 groups according to the intensity of the reported maltreatment-obtained by the CTQ score (comparison group, moderate degree of abuse and severe maltreatment). Results: The group that showed moderate maltreatment showed better performance in an attention task compared to the comparison group. At the severe maltreatment group, this difference was not observed. Conclusions: Children and adolescents who are victims of maltreatment are more alert to environmental details that surround them as a form of adaptation to defend themselves against potential threats. However, they could react precipitously with inappropriate behavior in some contexts. This can lead to a favorable environment for new and repeated situations of violence, abuse and a perpetuation of this victimization.

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 survival of mycelium and sclerotia of rhizoctonia solani ag1-1c was studied in eucalyptus sp. litter treated with the antagonists trichoderma longibrachiatum (ufv-1) and t. inhamatum (ufv-2 and ufv-3) isolates. for 12 months, r. solani survival in rhizoctonia infected eucalypt leaves, was apparently not affected by environmental factors, nor by possible naturally occurring antagonists. on the other hand, the sclerotial rate survival decreased progressively reaching 26%. the influence of trichoderma spp. isolates did not affect r. solani survival in eucalypt-infected leaves, but significant and continuous reduction of sclerotia viability was observed when compared to captan treatment, 25 days after treatment with the antagonists. the survival in the fungicide treatment reached significantly low levels in the first evaluation, but its efficiency decreased with time. progressive reduction and continuous survival of sclerotia was detected in the control as well, but significantly less than any other treatment.

Abstract: Marketing can be understood as the instrument used by companies to determine the needs of its customers and to create mechanisms in order to supply such needs and bring the company better chances of success. The financial sector in Brazil often involves great challenges; thus as to survive and grow in marketing it is necessary to implement some actions that enable greater proximity between companies and customers; to understand their needs and to be more flexible in order to offer more quality, individually. Currently, there is no significant differential used by the companies on their products and services, and therefore, it is necessary to create marketing strategies so as to achieve and maintain market share. Thus, the purpose of this paper is to evaluate the perception of quality in the services provided by a bank, located in Campina Grande, Paraíba, Brazil. Regarding the methodological aspects, this study is characterized as exploratory and descriptive, being a case study, with a quantitative analysis approach. The findings revealed that the agency still falls short in many criteria that concern its customers. Consequently, it is necessary that the company improves its employees’ qualification, starts to listen and respond to customers’ suggestions, and also has some flexibility in its services. Therefore, the agency should review the points that should be improved in order to prevent their customers to seek for services provided by other agencies that offer quality services.

Abstract: within the concept that hormones are regulated by a cycle of reciprocity, the fact that osteoblasts and adipocytes are developed from mesenchymal stem cells and that bone remodeling is regulated by leptin brings up the idea of possible bone participation in energy metabolism and vice-versa. recent studies have shown that the differentiation and function of these bone cells are regulated by leptin, which seems to trigger a bimodal response, via sympathetic nervous system, and a local response, in which leptin acts on the bone. in fact, studies have shown complex interactions between bone, adipose tissue and brain. however, there are few studies on crosstalk in patients with chronic kidney disease (ckd). these patients have a tendency to decreased bone mineral density and high levels of leptin. then, this article presented a review of potential involvement of adipose tissue and bone mass in patients with ckd.
