15. Determination of the regulatory properties of Yucca schidigera extracts on the biochemical parameters and plasma hormone levels associated with obesity
ABSTRACT Yucca schidigera Ortgies, Asparagaceae, is a herbaceous plant. Due to the high saponin content the powdered branches and leaves are used as natural food additive for human and animal. The aim of this study was to investigate the effects of Y. schidigera extracts on plasma leptin, ghrelin, adiponectin, insulin, thyroid hormones and some biochemical p

16. Evaluation of treatment with carboxymethylcellulose on chronic venous ulcers
Abstract BACKGROUND: Among the chronic leg ulcers, venous ulcers are the most common and constitute a major burden to public health. Despite all technology available, some patients do not respond to established treatments. In our study, carboxymethylcellulose was tested in the treatment of refractory chronic venous ulcers. OBJECTIVE: To evaluate the effica

17. OBTENÇÃO DE COMPÓSITOS HÍBRIDOS BASEADOS EM HIDROGÉIS E CIMENTO PORTLAND
In this study, a novel hybrid composite based on biodegradable hydrogel and Portland cement with promising technological properties was reported. In the first step, a full 23 with central point factorial design was utilized to obtain the enhanced polyacrylamide-carboxymethylcellulose hydrogel compositions. A mathematical model was devised, indicating that th

19. The effect of the inner cylinder rotation on the fluid dynamics of non-Newtonian fluids in concentric and eccentric annuli
Helical flow in an annular space occurs during oil drilling operations. The correct prediction of flow of drilling fluid in an annular space between the wellbore wall and the drill pipe is essential to determine the variation in fluid pressure within the wellbore. This paper presents experimental and CFD simulation results of the pressure drop in the flow of

20. An investigation of the behavior of a classifying hydrocyclone with pseudoplastic fluids
The procedure usually employed for specifying a set of hydrocyclones used in Newtonian fluid-solid separation processes can be extended to the case of non-Newtonian fluids. The apparent viscosity, µapp, is the link between the two cases, and can be evaluated from the knowledge of the shear stress function, S, and the characteristic rate of shear, λ*. In or

21. Influence of artificial saliva in biofilm formation of Candida albicans in vitro
Due to the increase in life expectancy, new treatments have emerged which, although palliative, provide individuals with a better quality of life. Artificial saliva is a solution that contains substances that moisten a dry mouth, thus mimicking the role of saliva in lubricating the oral cavity and controlling the existing normal oral microbiota. This study a

22. Ação hepatoprotetora do antioxidante quercitina no modelo esperimental de esteato-hepatite não alcoólica
Introduction: Non-alcoholic steatohepatitis is a disease with a high incidence, difficult diagnosis, and yet no effective treatment. This reasons lead to the use of experimental models for induction of NASH, and the study of routes developing this disease, as well as attempts to a effective therapy. Aims: This study was designed to develop an experimental mo

23. Efeito de tratamentos químicos, revestimentos comestíveis e irradiação na conservação de mamões minimamente processados / Effect of chemical treatments, edible coatings, and irradiation on fresh-cut papaya conservation
Avaliou-se o efeito de tratamentos químicos, revestimentos comestíveis e irradiação na conservação de mamões processados minimamente. Após seleção, lavagem e sanitização, os mamões foram descascados e cortados em meias rodelas, as quais foram submetidas a diferentes tratamentos, embaladas e armazenadas a 5±1°C e 90±2%UR. Os mamões PM foram a

24. Aplicações da celulose de palha de cana-de-açúcar: obtenção de derivados partindo de celulose branqueada e de biocompósitos com poliuretana obtida a partir de óleo de mamona (Ricinus communis L.) / Applications of sugarcane straw cellulose: obtainment of derivatives from bleached cellulose and biocomposites with polyurethane obtained from castor oil (Ricinus communis L.)
The sugarcane processing generates various agricultural byproducts such as bagasse and straw, which is considered one of the main waste generated due to the mechanization of the harvest in Brazil. Thus, the availability and composition of sugarcane straw have driven a great effort to develop technologies that provide its effective utilization. This study aim
