13. An evolutionary approach to mania studying Sardinian immigrants to Argentina
Objective: To ascertain lifetime prevalence of positivity to a screening questionnaire for bipolar disorders (BD) in Sardinian immigrants to Argentina and residents of Sardinia and assess whether such positivity affects quality of life (QoL) in either group. Our hypothesis is that screen positivity for BD may be more frequent in immigrants. Methods: Observ

14. Evolutionary analysis of apolipoprotein E by Maximum Likelihood and complex network methods
Abstract Apolipoprotein E (apo E) is a human glycoprotein with 299 amino acids, and it is a major component of very low density lipoproteins (VLDL) and a group of high-density lipoproteins (HDL). Phylogenetic studies are important to clarify how various apo E proteins are related in groups of organisms and whether they evolved from a common ancestor. Here, w

15. Challenging Mycobacterium tuberculosi s dormancy mechanisms and their immunodiagnostic potential
ABSTRACT Mycobacterium tuberculosis is the etiologic agent of tuberculosis, one of the world's greatest cause of morbidity and mortality due to infectious disease. Many evolutionary mechanisms have contributed to its high level of adaptation as a host pathogen. Prior to become dormant, a group of about 50 genes related to metabolic changes are transcribed by

16. Phylogenetic analysis of the emergence of main hepatitis C virus subtypes in São Paulo, Brazil
ABSTRACTBACKGROUND: It is recognized that hepatitis C virus subtypes (1a, 1b, 2a, 2b, 2c and 3a) originated in Africa and Asia and spread worldwide exponentially during the Second World War (1940) through the transfusion of contaminated blood products, invasive medical and dental procedures, and intravenous drug use. The entry of hepatitis C virus subtypes i

17. The best of both worlds: Phylogenetic eigenvector regression and mapping
Eigenfunction analyses have been widely used to model patterns of autocorrelation in time, space and phylogeny. In a phylogenetic context, Diniz-Filho et al. (1998) proposed what they called Phylogenetic Eigenvector Regression (PVR), in which pairwise phylogenetic distances among species are submitted to a Principal Coordinate Analysis, and eigenvectors are

18. Análisis ecológico de una red empresarial de turismo
ABSTRACT Objective: Institutionalism as an adaptation theory has contributed to understanding of the changing characteristics in governance structures. At the same time, community ecology has enhanced the evaluation of change within organizational communities. This study aims to analyze the relations and interactions of a business network, using institutio

19. Understanding Supply Networks from Complex Adaptive Systems
This theoretical paper is based on complex adaptive systems (CAS) that integrate dynamic and holistic elements, aiming to discuss supply networks as complex systems and their dynamic and co-evolutionary processes. The CAS approach can give clues to understand the dynamic nature and co-evolution of supply networks because it consists of an approach that incor

20. Weldability studies and parameter optimization of AISI 904L super austenitic stainless steel using friction welding
Welding input parameters play a very significant role in determining the quality of a weld joint. The quality of the joint can be defined in terms of mechanical properties, distortion and weld-bead geometry. Generally, all welding processes are employed with the aim of obtaining a welded joint with the desired characteristics. The purpose of this study is to

21. Do people adjust career choices according to socioeconomic conditions?: an evolutionary analysis of future discounting
The ability to process environmental cues and make advantageous choices has been fundamental during human evolution. Discounting future rewards is a capacity of our evolved mind and could be useful for understanding career decisions. This paper investigated the relationship between real-life plans, career choices, and income indicators based on an evolutiona

22. Enhanced lipase recovery through RSM integrated differential evolutionary approach from the fermented biomass
The aim of this work was to apply a modeling integrated optimisation approach for a complex, highly nonlinear system for an extracellular lipase extraction process. The model was developed using mutation, crossover and selection variables of Differential Evolution (DE) based on central composite design of Response Surface Methodology. The experimentally vali

23. Causação circular do crescimento das economias em desenvolvimento: uma ponte entre as abordagens evolucionária e pós keynesiana
Based on the Post Keynesian approach and on the Evolutionary literature, this study seeks to demonstrate the causal relationships between the National Innovation System and the national and international financial systems. This study shows that there is a circular causation in the less developed economies that contributes to the immaturity of its National In

24. Characterization of the omlA gene from different serotypes of Actinobacillus pleuropneumoniae: a new insight into an old approach
The OmlA protein is a virulence factor of Actinobacillus pleuropneumoniae, an important pathogen in pigs. The polymorphisms present in the omlA gene sequence of 15 reference serotypes of A. pleuropneumoniae and non-serotypable isolates were assessed to determine the possible evolutionary relationship among them and to validate the importance of this gene as
