In his famous phrase, Dobzhansky said "nothing in biology makes sense except in the light of evolution". By extension, in Neurosciences it could be interpreted as "nothing in neurosciences makes sense except in the light of behavior". The side blotched lizard Uta stansburiana has been widely used as a model organism to understand variation in repro­ductive strategies, which has greatly contributed to enrich the debate on the genetic basis of behavior and its consequences on the evolution of populations. Moreover, researching of Uta stransburiana has yielded interesting results about the modulation of behavior through conserved neuroendocrine pathways through the species; these data allow to establish the neuroendocrine substrate of conserved behavioral among several groups. This review synthesizes some behaviors that have contributed to the understanding of the evolution of morphological and behavioral traits sexual selection and can help to understand reproduc­tive behavior observed in other vertebrate groups.

The current condition of epidemiological and genetic knowledge of the cervical cancer (CC), as well as the development of probabilistic algorithms, allows the approximation of holistic diag­nosis of the CC. It is necessary to consider the interactions between the genome of the host, the viral genomes and the clinical factors of epidemiological risk. This review is divided into four sections: 1) the holistic tools for multivariate model of CC are described; 2) the genetic markers associated with susceptibility to malignant progression of cervical squamous intraepithelial lesions to CC development are explored; 3) the Human Papillomavirus (HPV) as the essential element for CC development is exposed; finally, 4) the clinical factors of risk associated with CC development are considered, such as smoking, sexual habits and risky sexual behavior, sexually transmitted infections and multiparity.

The investigation shows results on levels of job satisfaction in a sample of workers belonging to a top-level educational institution of the State of Mexico. The research was descriptive, cor­relational, explanatory transverse non-experimental design and performed with the universe population belonging to three categories: management and staffing, administrative and lectur­ers. In order to measure job satisfaction it was used Job Satisfaction Index (LSI*66) developed by [1]. The results showed that three of five factors predict job satisfaction and can increase levels of job satisfaction of the institution
