25. Corrosion Resistance Evaluation of HVOF Produced Hydroxyapatite and TiO2-hydroxyapatite Coatings in Hanks' Solution
The electrochemical behavior of HVOF produced hydroxyapatite (HA) and 80HA-20TiO2 coatings were investigated using electrochemical techniques in natural aerated Hanks' solution in the presence and absence of bovine serum albumin (BSA) for 30 days. All samples presented open circuit potential oscillations, which were associated to the porous nature of the coa

26. Phenolic Content and Biomolecule Oxidation Protective Activity of Globularia alypum Extracts
ABSTRACT The protective activity of methanolic (Met E) and aqueous (Aq E) extracts of Globularia alypum L. (G. alypum) against DNA, lipid and protein oxidative damage was investigated. Moreover, the scavenging, chelating, and reducing power activities of the extracts were also evaluated. Phytochemical analysis was performed to determine phenolic compounds. R

27. Development of VEGF-loaded PLGA matrices in association with mesenchymal stem cells for tissue engineering
The association of bioactive molecules, such as vascular endothelial growth factor (VEGF), with nanofibers facilitates their controlled release, which could contribute to cellular migration and differentiation in tissue regeneration. In this research, the influence of their incorporation on a polylactic-co-glycolic acid (PLGA) scaffold produced by electrospi

29. Studies of the Interaction between BSA and a Plumeran Indole Alkaloid Isolated from the Stem Bark of Aspidosperma cylindrocarpon (Apocynaceae)
Binding between bovine serum albumin (BSA) and a plumeran indole alkaloid (PIA) isolated from the stem bark of Aspidosperma cylindrocarpon (Apocynaceae) was studied by spectroscopic techniques (UV-Vis absorption, circular dichroism, steady state and time-resolved fluorescence), combined with molecular docking. Steady state and time resolved fluorescence data

30. Avaliação de concordância entre testes para diagnóstico da hanseníase
RESUMO Introdução: A hanseníase é uma doença infecciosa crônica causada pelo parasita intracelular Mycobacterium leprae. O diagnóstico é essencialmente clínico, com base em sintomas, exame da pele, nervos periféricos e história epidemiológica. Testes laboratoriais são realizados para complementar o resultado de diagnóstico clínico, ou mesmo s

31. rROP2 de Toxoplasma gondii como potencial vacina contra a eliminação de oocistos em gatos domésticos
Resumo O objetivo do presente estudo foi avaliar a eliminação de oocistos de Toxoplasma gondii em gatos imunizados pela via nasal com proteínas ROP2 de T. gondii. Doze gatos sem raça definida (Felis catus) foram divididos em três grupos experimentais G1, G2 e G3 (n = 4). Os animais do G1 receberam 100 μg de proteínas de rROP2 mais 20 μg de Quil-A, G2

32. Método de Hemaglutinação Indireta alterado para facilitar a sorotipificação de Haemophilus parasuis
RESUMO A Doença de Glässer é uma doença bacteriana emergente que afeta a produção de suínos em todo o mundo e causa importantes perdas econômicas. O agente etiológico, Haemophilus parasuis, é atualmente dividido em quinze sorovares; no entanto, um número crescente de cepas não tipificáveis tem sido relatado. O teste de hemaglutinação indireta

33. Aterogênese subclínica em pacientes com psoríase leve: um papel para IL-6?
Resumo Introdução: Foi postulada uma ligação entre psoríase e aterosclerose subclínica. A rede de citocinas pode intermediar essa associação. Poucos dados estão disponíveis em pacientes com psoríase leve. Avaliamos a espessura íntima-média carotídea (cIMT) em psoriáticos e controles livres de medicação. Paralelamente, pesquisamos a associa�

34. Adsorption of BSA (Bovine Serum Albuminum) and lysozyme on poly(vinyl acetate) particles
Abstract Poly(vinyl acetate) (PVAc) particles find many uses in the biomedical field, including the use as particle embolizers. Particularly, embolizing particles can combine physical and chemical effects when they are doped with pharmaceuticals. For this reason, the adsorption of bovine serum albuminum (BSA) and lysozyme (used as model biomolecules) on PVAc

35. GENETIC MUTATIONS AFFECTING THE FIRST LINE ERADICATION THERAPY OF Helicobacter pylori-INFECTED EGYPTIAN PATIENTS
SUMMARY Introduction: Several genetic mutations affect the first-line triple therapy for Helicobacter pylori. We aimed to study the most common genetic mutations affecting the metronidazole and clarithromycin therapy for H. pylori-infected Egyptian patients. Patients and Methods: In our study, we included 100 successive dyspeptic patients scheduled for dia

36. A Backtracking Search Algorithm for the Simultaneous Size, Shape and Topology Optimization of Trusses
Abstract This paper presents a Backtracking Search Optimization algorithm (BSA) to simultaneously optimize the size, shape and topology of truss structures. It focuses on the optimization of these three aspects since it is well known that the most effective scheme of truss optimization is achieved when they are simultaneously considered. The minimization of
