1. Bioprosthetic Aortic Valve Degeneration: a Review from a Basic Science Perspective
Abstract Introduction: The increase in the prevalence of aortic stenosis due to an aging population has led to an increasing number of surgical aortic valve replacements. Over the past 20 years, there has been a major shift in preference from mechanical to bioprosthetic valves. However, despite efforts, there is still no "ideal" bioprosthesis. It is crucial

2. Anti-Zika Virus Effects, Placenta Protection and Chemical Composition of Passiflora edulis Seeds Ethanolic Extract
Various beneficial biological activities have been reported for passion fruit (Passiflora edulis), grown in tropical and subtropical regions. However, no study has yet demonstrated its action against the Zika virus (ZIKV) infection. The present study aimed to investigate the anti-ZIKV of the ethanolic passion fruit seed extract (PFSE), from which, liquid chr

3. DETERMINAÇÃO DE MERCÚRIO EM FÍGADO DE TETRÁPODES MARINHOS POR ESPECTROMETRIA DE FLUORESCÊNCIA ATÔMICA ACOPLADA A GERAÇÃO DE VAPOR FRIO (CV-AFS) E ESPECTROMETRIA DE MASSA COM FONTE DE PLASMA INDUTIVAMENTE ACOPLADO (ICP-MS): UMA COMPARAÇÃO SISTEMÁTICA ENTRE AS DUAS TÉCNICAS
This study compares the techniques cold vapour atomic fluorescence spectrometry (CV-AFS) and inductively coupled plasma mass spectrometry (ICP-MS) for the determination of Hg in biological samples (hepatic tissue from marine tetrapods). Acid digestions were performed for the samples and aliquots of them were analysed by ICP-MS and CV-AFS. To minimize the Hg

4. Upconversion 3D Printed Composite with Multifunctional Applications for Tissue Engineering and Photodynamic Therapy
Upconversion nanoparticles (UCNPs) are suitable materials for bioapplications due to their ability to emit visible light under near infrared (NIR) excitation, in the biological transparency range. Polycaprolactone(PCL)-based scaffolds are widely used in tissue engineering in combination with inorganic compounds to improve bioactivity and osteoconductive prop

5. Relationships among oncostatin M, insulin resistance, and chronic inflammation: a pilot study
ABSTRACT Objective Activated macrophages (M1-type macrophages) in adipose tissue secrete many proinflammatory cytokines that induce insulin resistance (IR). Oncostatin M (OSM), a member of the interleukin-6 (IL-6) family of Gp130 cytokines, plays an important role in a variety of biological functions, including the regulation of inflammatory responses.

7. In vitro Evaluation of PHBV/PCL Blends for Bone Tissue Engineering
The objective of this study was to evaluate Vero cells in in vitro biocompatibility tests with pure PHBV and PCL and 75/25 and 50/50 blends developed for bone tissue bioengineering in dense or porous forms. The biomaterials were characterized morphologically by scanning electron microscopy, (SEM) stereoscopic imaging (SI), and micrometer measurement. Cellula

8. Mineral deposition promoted by resin-based sealants with different calcium phosphate additions
Abstract The aim of this study was to evaluate the influence of different calcium phosphates (CaPs) on the physical, biological, and remineralizing properties of experimental resin-based sealants (RBSs). Triethylene-glycol dimethacrylate (90wt%) and bisphenol A-glycidyl methacrylate (10wt%) were used to produce resin-based sealants. Hydroxyapatite (SHAp), α

10. Fibrin biopolymer as scaffold candidate to treat bone defects in rats
ABSTRACT Background: Bone tissue repair remains a challenge in tissue engineering. Currently, new materials are being applied and often integrated with live cells and biological scaffolds. The fibrin biopolymer (FBP) proposed in this study has hemostatic, sealant, adhesive, scaffolding and drug-delivery properties. The regenerative potential of an associat
