13. Epitope of dengue virus E protein detect human antibodies associated with mild disease: a potential peptide for vaccine development
ABSTRACT The antigenic potential of seven immunogenic peptides of the dengue virus was evaluated in the sera of patients with dengue confirmed by IgM/IgG serology. Antibodies IgM and IgG against dengue virus peptides were analyzed by ELISA in 31 dengue sero-positive and 20 sero-negative patients. The P5 peptide showed significant IgG immunoreactivity mostly

14. Effect of Artemisia apiacea Hance on growth performance, cecal opportunistic bacteria, and microbicidal peptides in rabbits
ABSTRACT This study aimed to investigate the effect of Artemisia apiacea Hance supplementation on growth performance, cecal opportunistic bacteria, and antimicrobial defense using 120 rabbits. There were four experimental diets containing a control and A. apiacea Hance added at doses of 25, 50, and 75 g kg−1 of feed. The trial lasted for 70 days. The resul

15. Proteins and Peptides at the Interfaces of Nanostructures
Abstract: The present review focuses on the proteins and peptides at the interfaces of nanostructured metals and semiconductors as a result of their use in synthesis in-situ and functionalization of nanostructures. We start the review with an introduction about the peculiar properties of nanostructured materials and their applications. In the following, the

16. Enhanced antioxidant activity of okara through solid state fermentation of GRAS Fungi
Abstract The enhancement of antioxidant activity of fermented okara was investigated using fungal solid-state fermentation. The initial fungal concentration and water activity were found to influence the enhanced antioxidant capacity of fermented okara. Extracellular enzymes, especially proteases and carbohydrases might facilitate the hydrolysis of okara pro

17. Inhibition of the Angiotensin I Converting Enzyme (ACE) and proteolysis of non-fat probiotic yogurt
Resumo O iogurte é uma importante fonte de muitos peptídeos biologicamente ativos que podem apresentar benefícios específicos à saúde. A maioria dos peptídeos bioativos produzidos durante a produção de iogurte está relacionada aos peptídeos inibidores da enzima conversora da angiotensina (ECA-I). O presente estudo avaliou a proteólise e as ativid

18. N-Myristoyltransferases as antileishmanial targets: a piggyback approach with benzoheterocyclic analogues
Leishmaniasis is one of the neglected diseases that remain in need for pharmacological alternatives. In this context, N-Myristoyltransferases (NMT) arise as interesting targets to explore since they are involved in the co/post-translational processing of peptides which are responsible for host cell invasion. Studies that consider these enzymes as targets poi

19. Fluid and hemodynamic management in hemodialysis patients: challenges and opportunities
Resumo O volume de fluidos e o controle hemodinâmico em pacientes em hemodiálise é um componente essencial da adequação da diálise. A restauração da homeostase do sal e da água em pacientes em hemodiálise tem sido uma busca constante por parte dos nefrologistas, no que condiz à abordagem do “peso seco. Embora essa abordagem clínica tenha sido a

20. Linear Peptide Analogues from Jatropha’s Orbitides Promote Migration of Human Neonatal Foreskin Fibroblasts in vitro and Collagen Deposition
Orbitides are a class of small naturally occurring cyclic peptides with structural and functional diversities. Their chemical properties make this class feasible to be obtained by solid phase peptide synthesis (SPPS). Therefore, this synthetic accessibility enables useful application and facilitates the identification of analogues, bioactivity studies, and t

23. Association of vitamin D3, VDR gene polymorphisms, and LL-37 with a clinical form of Chagas Disease
Abstract INTRODUCTION: Chagas disease (CD) is an important public health problem in Brazil and worldwide. Aging and obesity are important matters in patients with CD, as is hypovitaminosis D3, which can decrease the quality of life of these patients. Immunomodulation mediated by vitamin D3, especially the production of antimicrobial peptides such as cathel

24. Protein identification from the parotoid macrogland secretion of Duttaphrynus melanostictus
ABSTRACT Background: Bufonid parotoid macrogland secretion contains several low molecular mass molecules, such as alkaloids and steroids. Nevertheless, its protein content is poorly understood. Herein, we applied a sample preparation methodology that allows the analysis of viscous matrices in order to examine its proteins. Methods: Duttaphrynus melanostic
