1. MÉTODO DE TRIAGEM DE MICROGININAS EM CIANOBACTÉRIAS POR LC-MS/MS
Cyanobacteria produce a wide variety of bioactive compounds, making them a highly promising group in the search for novel molecules with pharmacological and biotechnological properties. Among these, microginins attract attention for being peptides which inhibit angiotensin-converting enzyme, turning them into potential targets for hypertension and congestive

2. Low fat goat meat sausage with chitosan-glucose Maillard reaction product: impact on quality and shelf life
Abstract Low fat fresh goat sausages based on chitosan (LMWC) and derivative chitosan (LMWC-Glc) were developed aiming to produce a functional food product evaluating the effect of inclusion of these compounds on quality, stability and shelf life. Goat sausages (10% pork fat) were formulated with 2% (w/w) of LMWC or LMWC-Glc and stored at 4 °C during 21 day

4. Cardioprotective effect of lipstatin derivative orlistat on normotensive rats submitted to cardiac ischemia and reperfusion
Abstract Purpose: To evaluate in vivo animal model of cardiac ischemia/reperfusion the cardioprotective activity of pancreatic lipase inhibitor of the orlistat. Methods: Adult male Wistar rats were anesthetized, placed on mechanical ventilation and underwent surgery to induce cardiac I/R by obstructing left descending coronary artery followed by reperfusi

5. Synthesis and antimicrobial evaluation of two peptide LyeTx I derivatives modified with the chelating agent HYNIC for radiolabeling with technetium-99m
Abstract Background Current diagnostic methods and imaging techniques are not able to differentiate septic and aseptic inflammation. Thus, reliable methods are sought to provide this distinction and scintigraphic imaging is an interesting option, since it is based on physiological changes. In this context, radiolabeled antimicrobial peptides have been inve

6. Interval and continuous exercise enhances aerobic capacity and hemodynamic function in CHF rats
OBJECTIVE: The aim of the present study was to compare the effects of continuous versus interval aerobic exercise training on hemodynamic parameters, cardiac remodeling, and maximal exercise capacity (MEC) in chronic heart failure (CHF) rats.METHOD: Twenty-four male Wistar rats were subjected to myocardial infarction (MI) surgery. Five weeks post MI, the ani

7. A time-domain finite element model reduction method for viscoelastic linear and nonlinear systems
AbstractMany authors have shown that the effective design of viscoelastic systems can be conveniently carried out by using modern mathematical models to represent the frequency- and temperature-dependent behavior of viscoelastic materials. However, in the quest for design procedures of real-word engineering structures, the large number of exact evaluations o

9. Rational design of diagnostic and vaccination strategies for tuberculosis
The development of diagnostic tests which can readily differentiate between vaccinated and tuberculosis-infected individuals is crucial for the wider utilization of bacillus Calmette-Guérin (BCG) as vaccine in humans and animals. BCG_0092 is an antigen that elicits specific delayed type hypersensitivity reactions similar in size and morphological aspects to

10. Implementação e avaliação de desempenho de estratégias de controle aplicadas em um sistema de armazenamento refrigerado / Implementation and performance evaluation of control strategies applied in a storage system for refrigerated
The cold storage of agricultural products intended to meet a demand for healthier products by markets and consumers. You can also give producers an alternative to extend the time for the marketing of products stored. Cold storage is important for a better conservation of perishable products. Because with the decrease in storage temperature, the metabolic rea

11. Active-set strategy in Powell's method for optimization without derivatives
In this article we present an algorithm for solving bound constrained optimization problems without derivatives based on Powell's method [38] for derivative-free optimization. First we consider the unconstrained optimization problem. At each iteration a quadratic interpolation model of the objective function is constructed around the current iterate and this

12. Two derivative-free methods for solving underdetermined nonlinear systems of equations
In this paper, two different approaches to solve underdetermined nonlinear system of equations are proposed. In one of them, the derivative-free method defined by La Cruz, Martínez and Raydan for solving square nonlinear systems is modified and extended to cope with the underdetermined case. The other approach is a Quasi-Newton method that uses the Broyden
