13. Effect of pre-exercise carbohydrate availability on fat oxidation and energy expenditure after a high-intensity exercise
The aim of this study was to test the hypothesis that reduced pre-exercise carbohydrate (CHO) availability potentiates fat oxidation after an exhaustive high-intensity exercise bout. Eight physically active men underwent a high-intensity exercise (∼95% V̇O2max) until exhaustion under low or high pre-exercise CHO availability. The protocol to manipulate pr

14. Indução de resistência à Macrophomina phaseolina em soja tratada com extrato de alecrim
RESUMO Extratos vegetais podem induzir mecanismos de resistência de plantas em função da presença de compostos com características eliciadoras. O objetivo deste estudo foi avaliar o efeito do extrato bruto de alecrim nas concentrações 0%; 1%; 2,5% e 5% sobre a atividade de peroxidase, polifenoloxidase e fenilalanina amônia-liase (FAL) em soja inocula

15. TRATAMENTO ELETROQUÍMICO DE EFLUENTE DA PRODUÇÃO DE BIODIESEL USANDO UM ELETRODO DO TIPO ADE: Ti/IrO2-Nb2O5
This work presents the electrochemical treatment of wastewater of biodiesel production, using DSA based on IrO2 and Nb2O5. The anode was prepared by modified Pechini method and characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD), in order to evaluate structural and morphological properties and by electrochemical impedance spectros

16. Construction of Mycobacterium tuberculosis cdd knockout and evaluation of invasion and growth in macrophages
Cytidine deaminase (MtCDA), encoded by cdd gene (Rv3315c), is the only enzyme identified in nucleotide biosynthesis pathway of Mycobacterium tuberculosis that is able to recycle cytidine and deoxycytidine. An M. tuberculosis knockout strain for cdd gene was obtained by allelic replacement. Evaluation of mRNA expression validated cdd deletion and showed the a

17. Effect of prophylactic non-invasive mechanical ventilation on functional capacity after heart valve replacement: a clinical trial
OBJECTIVE: During cardiac surgery, several factors contribute to the development of postoperative pulmonary complications. Non-invasive ventilation is a promising therapeutic tool for improving the functionality of this type of patient. The aim of this study is to evaluate the functional capacity and length of stay of patients in a nosocomial intensive care

18. Protection mediated by chemokine CXCL10 in BALB/c mice infected by Leishmania infantum
BACKGROUND Visceral leishmaniasis (VL) caused by Leishmania infantum is characterised by the loss of the ability of the host to generate an effective immune response. Chemokines have a direct involvement in the pathogenesis of leishmaniasis, causing a rapid change in the expression of these molecules during infection by Leishmania. OBJECTIVES Herein, it

19. A newly validated high-performance liquid chromatography method with diode array ultraviolet detection for analysis of the antimalarial drug primaquine in the blood plasma
Abstract INTRODUCTION: Primaquine (PQ) diphosphate is an 8-aminoquinoline antimalarial drug with unique therapeutic properties. It is the only drug that prevents relapses of Plasmodium vivax or Plasmodium ovale infections. In this study, a fast, sensitive, cost-effective, and robust method for the extraction and high-performance liquid chromatography with

20. Evaluation of short-chain-length polyhydroxyalkanoate accumulation in Bacillus aryabhattai
Abstract This study was focused on the polyhydroxybutyrate (PHB) accumulation property of Bacillus aryabhattai isolated from environment. Twenty-four polyhydroxyalkanoate (PHA) producers were screened out from sixty-two environmental bacterial isolates based on Sudan Black B colony staining. Based on their PHA accumulation property, six promising isolates we

21. Comportamento ingestivo e parâmetros sanguíneos em ovinos que receberam dietas contendo aditivos à base de extratos de própolis em pó
RESUMO Objetivou-se avaliar os efeitos do extrato de própolis (LLOSC2) sobre o comportamento ingestivo e os parâmetros sanguíneos em cordeiros alimentados com dieta concentrada. Foram utilizados quatro cordeiros machos, castrados, sem raça definida e com peso médio inicial de 32±1,92kg, mantidos em gaiolas metabólicas individuais durante todo o perío

22. Characterisation of iunH gene knockout strain from Mycobacterium tuberculosis
BACKGROUND Tuberculosis (TB) is an infectious disease caused mainly by the bacillus Mycobacterium tuberculosis. The better understanding of important metabolic pathways from M. tuberculosis can contribute to the development of novel therapeutic and prophylactic strategies to combat TB. Nucleoside hydrolase (MtIAGU-NH), encoded by iunH gene (Rv3393), is an

23. ACTIVIDAD REPRODUCTIVA Y DIETA DE HEMIDACTYLUS FRENATUS (SAURIA: GEKKONIDAE) EN EL NORTE DE COLOMBIA
ABSTRACT Despite its success as an invasive species, little is known about the ecological aspects of the gekkonid lizard Hemidactylus frenatus in Colombia. In the present study the size at maturity, sexual dimorphism, reproductive activity, and diet composition of a population of this species in an urban locality of Northern Colombia were determined. We cond

24. Cytotoxicity and cytokine expression induced by silorane and methacrylate-based composite resins
ABSTRACT The successful use of composite resins in Dentistry depends on physicochemical properties, but also on the biological compatibility of resins, because of the close association between pulp and dentin. Objective The aim of this study was to evaluate cytotoxicity and cytokine production induced by light-cured or non-light-cured methacrylate-based an
