1. Structural Integrity and Cellular Viability of Cryopreserved Allograft Heart Valves in Right Ventricular Outflow Tract Reconstruction: Correlation of Histopathological Changes with Donor Characteristics and Preservation Times
Abstract Introduction: Cryopreserved allograft heart valves (CAHV) show longer event-free survival compared to other types of protheses. However, all patients develop early and/or late allograft failure. Negative predictors are clinical, and there is a lack of evidence whether they correspond with the microscopic structure of CAHV. We assessed histopatholog

2. Custodiol versus Blood Cardioplegia: Comparison of Myocardial Immunohistochemical Analysis and Clinical Outcomes
ABSTRACT Introduction: Custodiol (histidine-tryptophan-ketoglutarate) and repetitive blood cardioplegia are the solutions for myocardial protection and cardiac arrest. In this study, we aimed to compare immunohistochemical analysis, clinical outcomes, and cardiac enzyme values of Custodiol and blood cardioplegia groups. Methods: This was a randomized prosp

3. Capital, ideologia e uma história do mundo sob o prisma da desigualdade
The phytochemical reinvestigation from the heartwood of the extracts of Cordia glazioviana led to the isolation of four still undescribed hydroquinones derivatives designated as cordiaquinol D (1), cordiaquinol E (2), (10R)-10,11-dihydrofuran-1,4-dihydroxy-globiferin (3) and 2-[(1’E,6’E)-3’,8’- dihydroxy-3’,7’-dimethylocta-1’,6’-dienyl]-benze

5. Optimum Positioning of Base Station for Cellular Service Devices Using Discrete Knowledge Model
Abstract A good wireless network design depends on technical and financial viability and a number of other criteria that must be met. Following the emergence of new technologies and services, such as 5G transmission and the reuse of frequencies, new work is being carried out to ensure a better design for a particular area. This study examines a discrete radi

6. Antioxidant-mediated protective role of Hericium erinaceus (Bull.: Fr.) Pers. against oxidative damage in fibroblasts from Friedreich’s ataxia patient
Abstract Friedreich’s ataxia (FRDA) is a progressive neuromuscular disorder caused by substantial decrease of mitochondrial protein frataxin responsible for biogenesis of iron-sulphur clusters and protection from oxidative damage. In this study, we investigated the antioxidant activities of a standardized aqueous extract from fruiting bodies of Hericium er

7. Cachaça production from sugarcane infested by Diatrea saccharalis
Abstract Cachaça is a highly consumed Brazilian spirit, which still needs studies on its agroindustrial processing. We can highlight the effects of infestation of pest insects in the sugarcane, and the chemical-physically characteristics of the drink. So, the aim of the study was to evaluate the consequences of the infestation of the sugarcane borer (Diatre

10. Evaluation of cell damage and modulation of cytokines TNF-α, IL-6 and IL-10 in macrophages exposed to PpIX-mediated photodynamic therapy
Resumo Pouco se sabe se a morte celular induzida pela terapia fotodinâmica (PDT) compromete os macrófagos (MΦ), envolvidos nas respostas imunes induzidas pela PDT. Neste estudo, foram avaliados parâmetros de citotoxicidade dos MΦ mediada pela PDT e a produção de citocinas, frente à protoporfirina IX (PpIX). MΦ peritoneais de camundongos BALB/c foram

11. Obtenção de scaffolds bioabsorvíveis a partir de blenda de PLGA e IR com adição de hidroxiapatita
RESUMO A obtenção de scaffolds bioativos a partir da blenda polimérica de poli (ácido láctico-co-glicólico) (PLGA) e poliisopreno (IR) com diferentes adições de Hidroxiapatita (HAp) é proposta como uma alternativa à engenharia de tecidos. Para o preparo das soluções poliméricas, a blenda de PLGA/IR e a HAp foram dissolvidas em clorofórmio. Post

12. Propolis polyphenolic compounds affect the viability and structure of Helicobacter pylori in vitro
ABSTRACT To evaluate the anti-Helicobacter pylori activity of the major polyphenol compounds of propolis and their cellular damage, both as single molecule or in combination. Honey bees propolis were fractionated by using CPC and preparative HPLC. Four major polyphenols (chrysin, pinocembrin, galangin and caffeic acid phenethyl ester) were identified by thin
