This article presents some aspects of the relationship between the philosophies of Frege and Stuart Mill, from the standpoint of the fregean critic of psychologism and empiricism. I defend the thesis that, in Foundations of Arithmetic, Frege directs his criticism to the empiricism professed by Mill in his System of Logic; this critic does not constitutes a ‘charge’ of the English philosopher as being a psychologist. For this, we presented several aspects concerning the role that the antipsicologismo has in the Fregean thought and its direct relationship with the logicist project of reduction of arithmetic to logic. To defend our thesis, some arguments intended to show that empiricism not necessarily and directly imply psychologism are presented.

Mesenchymal stem cells (MSCs) are adult multipotent cells with fibroblastoid morphology and adherent to plastic. Furthermore, they can be obtained from different sources. Besides bone marrow, these cells are taken from umbilical cord blood, umbilical vein, saphenous vein, peripheral blood, arteries, liver and fetal pancreas, placenta, dental pulp and adipose tissue. MSCs derived from adipose tissue are important because of the abundant number of cells that can be obtained from this tissue, easy access and little discomfort to the patient. This study compared two techniques for obtaining MSCs from adipose tissue: mechanical dissociation (MD) and enzymatic digestion (ED). We also analyzed the inter-species cross-reactions using commercial monoclonal antibodies directed against surface antigens of stem cells from different species: mouse, horse, rabbit, monkey and human. We found that MD technique is favorable in relation to ED within 15 days of culture, and ED is more efficient in the first days of culture. The data also showed that MD causes less damage to cellular DNA. About inter-species cross-reactions, the monoclonal antibody A69 directed against stem cells from rabbits, which can be used in veterinary medicine, particularly in research involving horses

Human beings' motor capacity development is essential, because it facilitates movement, enabling the performance of motor activities and others. In pre-school, boys and girls acquire the motor capacity development considered basic that, through several factors such as neurological maturation, which is in charge of providing more complete movements, and body growth, which has the goal of a better body domain, makes them improve individually the performance of motor abilities, but it can minimize them if laterality does not develop spontaneously. There by, this study focused on assessing the neurological development between genders of students engaging in fundamental school. Forty-three children of both genders at age six took part in this study. The evaluation occurred through the LEFÉVRE protocol (1976), which aims at assessing the maturity and development of the Nervous System through tests of the Evolutionary Neurological Exam (ENE), which comprises a series of tests involving specific tasks, regarding age in the static balance items, dynamic balance, appendicular coordination, trunk-member coordination, motor persistency, sensibility and synkinesis. Neurological development comparisons were performed between boys and girls for each item of the battery of tests. The results of the motor persistency and sensitiveness and sensorial activity tests were below the average for six-year-old children, but there was not any difference in gender comparison for each item of the battery of tests, only a small tendency for one of the genders, but meaningless, having a variance in only two tests of the synkinesis exam (Foot-hand and paper ball with the dominant hand), in which boys had a bigger percentage of synkinesis presence than girls did. The results also showed that the majority of the children assessed, both boys and girls have a right manual and pedal preference and the ocular laterality is approximately the same for left and right-handers. It was..
