14. A brief review on hydroxyapatite production and use in biomedicine
Resumo A hidroxiapatita (HAp) é uma biocerâmica amplamente estudada devido à sua similaridade química com o componente mineral dos ossos. Além disso, é biocompatível, bioativa e termodinamicamente estável no fluido corporal, o que a coloca como um material atraente para uma ampla gama de aplicações no campo biomédico. Diversos esforços têm sido

15. On Estimation of Adhesive Strength of Implants Bioactive Coating with Titanium by Density Functional Theory and Molecular Dynamics Simulations
One of the ways to improve and accelerate osseointegration of a surgical implant with bone is application of biocompatible coatings, in particular, hydroxyapatite (HAp). Since the cases of delamination of the coating take place in dental practice, it is very important to estimate the adhesive strength of HAp with the implant. A measure of the coating-to-subs

17. Efectos de tratamientos térmicos post-alcalinos sobre las propiedades superficiales de titanio para implantes dentales con diferentes recubrimientos
ABSTRACT Titanium is widely used as dental implant since it is bio-inert and osseointegratable. However, provided that this material cannot induce bone growth from its surface, it is usual to carry out different surface treatments in order to develop bioactive coatings that increase both the initial rate of bone development and the biological anchorage of im

20. Titanium Coating with Hydroxyapatite and Chitosan Doped with Silver Nitrate
Biomaterials are effective alternatives for tissue substitution, including the bone tissue, since they do not pose risks of transmission of diseases or immune rejection. Nowadays, there is an interest in new materials capable of being associated with other substances which favor bone formation, especially natural biopolymers, in particular chitosan, which ma

21. Partial-hydrothermal hydrolysis is an effective way to recover bioactives from turmeric wastes
Abstract Partial-hydrothermal hydrolysis using pressurized hot water was applied in waste turmeric, derived from extraction processes that employed supercritical and pressurized fluids, as a sustainable alternative for the recovery of bioactive constituents from this material. The reaction products consisted of a liquid extract of fermentable sugars and a so

22. New seminal variety of Stevia rebaudiana: Obtaining fractions with high antioxidant potential of leaves
ABSTRACT The aim of this study was to determine the composition and antioxidant potential of leaves of a new variety of Stevia rebaudiana (Stevia UEM-13). Stevia leaves of UEM-13 contain rebaudioside A as the main glycoside, while most wild Stevia plants contain stevioside. Furthermore can be multiplied by seed, which reduces the cost of plant culture techni

23. Obtaining anthocyanin-rich extracts from frozen açai (Euterpe oleracea Mart.) pulp using pressurized liquid extraction
Abstract Açai is considered a functional food, and in addition to being a source of energy and fiber, it is a valuable source of bioactive compounds such as anthocyanins, minerals and fatty acids. In the present work, antioxidant-rich extracts from açai pulp were obtained using pressurized liquid extraction (PLE). The effects of the independent variables,

24. HPLC-DAD PROFILE OF PHENOLIC COMPOUNDS, CYTOTOXICITY, ANTIOXIDANT AND ANTI-INFLAMMATORY ACTIVITIES OF THE AMAZON FRUIT Caryocar villosum
Piquiá (Caryocar villosum - Caryocaraceae) is a native fruit from the Amazon region rich in bioactive substances. Fruit pulp extracts were analyzed by HPLC, together with extracts obtained from fruit pulp industry residual parts, byproducts such as husks (shells) and seeds. Extracts were prepared with two ethanolic solvent systems. Phenolic substances ellag
