13. Effect of CRABP2 on the proliferation and odontoblastic differentiation of hDPSCs
Abstract: Cellular retinoic acid-binding protein 2 (CRABP2) has been detected in several organs during embryonic development. Recent studies have demonstrated that CRABP2 plays important roles in the retinoic acid, β-catenin and Notch signaling pathways, as well as in the interaction between epithelial and mesenchymal cells, which are important for human de

14. Identification of the difference in the pathogenesis in heart failure arising from different etiologies using a microarray dataset
OBJECTIVES: Clinically, patients with chronic heart failure arising from different etiologies receive the same treatment. However, the prognoses of these patients differ. The purpose of this study was to elucidate whether the pathogenesis of heart failure arising from different etiologies differs. METHODS: Heart failure-related dataset GSE1145 was obtained

15. Fibers Obtained from Alginate, Chitosan and Hybrid Used in the Development of Scaffolds
The main aim of this study was to develop scaffolds based on alginate, chitosan and hybrid fibers with and without glycerol. The scaffolds developed underwent assessments for tensile property, swelling ratio and weight loss, cellular viability, degradation and biomineralization, as well as DSC/TGA thermal analysis. Tenacity values showed that use of glycerol

16. Numerical Study on the Projectile Impact Resistance of Multi-Layer Sandwich Panels with Cellular Cores
Abstract The projectile impact resistance of sandwich panels with cellular cores with different layer numbers has been numerically investigated by perpendicular impact of rigid blunt projectile in ABAQUS/Explicit. These panels with corrugation, hexagonal honeycomb and pyramidal truss cores are impacted at velocities between 50 m/s and 202 m/s while the relat

17. Microbial interactions: ecology in a molecular perspective
ABSTRACT The microorganism-microorganism or microorganism-host interactions are the key strategy to colonize and establish in a variety of different environments. These interactions involve all ecological aspects, including physiochemical changes, metabolite exchange, metabolite conversion, signaling, chemotaxis and genetic exchange resulting in genotype sel

18. SISTEMAS CARREADORES LIPÍDICOS NANOESTRUTURADOS PARA IVERMECTINA E METOPRENO VISANDO CONTROLE DE PARASITAS
The study of characteristics of nanoscale structures and applications now has great interest of researchers from different areas. In this regard, lipid carriers can improve the bioavailability of drugs and the reduction of possible toxicological effects. Thus, the development of nanostructured systems for the agricultural sector, aimed at combating parasites

19. Interaction of dental pulp stem cells with Biodentine and MTA after exposure to different environments
ABSTRACT Objective: The aim of the present study was to evaluate and compare the cytotoxic effects of Biodentine and MTA on dental pulp stem cells (DPSCs) and to assess cell viability and adherence after material exposure to an acidic environment. Material and Methods: DPSCs were cultured either alone or in contact with either: Biodentine; MTA set for 1 ho

20. Exposure to 50 Hz electromagnetic field changes the efficiency of the scorpion alpha toxin
AbstractBackground Extremely low-frequency (50 Hz) electromagnetic field (ELF-EMF) is produced by electric power transmission lines and electronic devices of everyday use. Some phenomena are proposed as “first effects” of ELF-EMF: the discrete changes in the membrane potential and the increase of the calcium channel activity as well as the intracellular

21. pTcGW plasmid vectors 1.1 version: a versatile tool for Trypanosoma cruzi gene characterisation
The functional characterisation of thousands of Trypanosoma cruzi genes remains a challenge. Reverse genetics approaches compatible with high-throughput cloning strategies can provide the tool needed to tackle this challenge. We previously published the pTcGW platform, composed by plasmid vectors carrying different options of N-terminal fusion tags based on

22. Role of cyclooxygenase-2 in Trypanosoma cruzisurvival in the early stages of parasite host-cell interaction
Chagas disease, caused by the intracellular protozoan Trypanosoma cruzi, is a serious health problem in Latin America. During this parasitic infection, the heart is one of the major organs affected. The pathogenesis of tissue remodelling, particularly regarding cardiomyocyte behaviour after parasite infection and the molecular mechanisms that occur immediate

23. Update on cutaneous tuberculosis
Tuberculosis continues to draw special attention from health care professionals and society in general. Cutaneous tuberculosis is an infection caused by M. tuberculosis complex, M. bovis and bacillus Calmette-Guérin. Depending on individual immunity, environmental factors and the type of inoculum, it may present varied clinical and evolutionary aspects. Pat

24. Dynamics of the interaction between body fluid and Ti cp: the influence of surface functionalization in the first stages of osseointegration
INTRODUCTION: Regenerative therapies using biomaterials require accurate information on interactions between the implanted material and the human body. To improve the process of bone regeneration it is necessary to obtain a better understanding of the influence of the surfaces on the early stages of osseointegration. This work aims to investigate the dynamic
