This study was developed with the aim of evaluating recombinant bovine somatotropin (rbST) on non-carcass components of goat kids of three genotypes. It was used 23 male goat kids of three genotypes, being 8 Alpine, 4 ½ Boer + ½ Alpine (½ BA) and 11 ¾ Boer + ¼Alpine (¾ BA), from which 12 received rbST e 11 control. The growth hormone used was the recombinant bovine somatotropin (rbST) and animals of treatment 1 received the hormone in the amount of 0.3 mg/kg live weight, from 45 days, adjusted in intervals of 14 days. Animals of treatment 2 (control) received saline solution in the same dosage and interval. The ½ BA goats presented a higher proportion of external non-carcass components (head, feet and skin) in relation to Alpine goats. Regarding the vital organs, such as lungs, kidneys and spleen, and the non-carcass components blood, internal fat and perinephric fat, Alpine goats presented higher values than ¾ BA goats. The administration of recombinant bovine somatotropin (rbST) did not produce effect on proportions and weight of non-carcass components. Proportions and weight of non-carcass components varied in function of genotypes, although animals were slaughtered at similar live weight.

The species of Tabebuia are propagated sexually, and the use of high-quality seeds is crucial to achieving success in restoration of degraded areas, timber and medicinal production. Thus, the use of rapid tests in programs to control seed quality is an essential tool for the assessment of their physiological quality. The objectives of the present study were to establish the methodology for conducting the tetrazolium test in seeds of T. roseoalba and verify seed viability as a function of storage time, evaluating germination parameters and comparing them with the results of the tetrazolium test. The fruits were manually harvested at the opening, and fresh seeds and seeds stored up to 24 months were evaluated by tetrazolium test, germination, emergence, length and dry weight of seedlings. The tetrazolium at a concentration of 0.05% at 36 ° C for 24 hours is indicated to assess the viability of T. roseoalba, and during storage germination, length and dry weight of the seedlings are reduced and the germination in nursery is sharply reduced with seed storage in 24 months.

Sibutramine is a drug recommended clinically for the treatment of obesity, but there are women that use the drug for maintenance of body weight. Many time this use occur associate to habit of tabagism, being the nicotine the main toxic compound in the cigarette. The goal of study was to evaluate the side effects promoted by sibutramine, associated or not to nicotine, in the reproductive tissue of adult female rats. Wistar animals (n = 30), were distributed in the groups: a) Control A (0.3 mL of distilled water; oral); b) Sibutramine (15 mg/kg of body weight; oral); c) Control B (0.3 mL of saline solution; intraperitoneal); d) Nicotine (4.0 mg/kg of body weight; intraperitoneal); e) sibutramine + nicotine. The treatments were conducted during 30 consecutive days (single dose, daily). Sibutramine, associated or not to nicotine, affected the folliculogenesis and luteogenesis. There were significant alterations (p<0.05) in the thickness of uterine layers, considerate each treatment. In conclusion, the administration isolated of sibutramine or nicotine promoted deleterious effects in the reproductive tissues of female rats and these effects were potential in the group that received both drugs.

In a previous research, it was observed that are symbolic exchanges established between the persons and the environment they live in that allow them to interact with others, leading them to reorganize their internal cognitive structures, reaching more elaborated stages. In the case of a person with deafness, the possibility of exchange can be compromised and knowledge about the construction of the temporal notion seems to be essential to enable a path of explanation about the difficulties they have regarding their cognitive development. Thus, based on the theory of Jean Piaget, the study intended to understand how the temporal notion constitutes as possible subject to the process of building the real, and examine, through empirical evaluation, if the difficulty in establishing symbolic exchanges caused by deafness would compromise the development of this notion. For this purpose, bibliographical research and empirical research were made, by the comparative evaluating between the performance of deaf and hearing subjects in relation to the construction of temporal notion. Two groups of subjects aged between 10 and 12 years were composed: one with three deaf subjects and another with 3 listeners. The assessment and analysis of the data were based on an experiment created by Piaget and his staff. The results showed that the listeners present responses from operative level, compatible with the age range in which they found themselves. In contrast, the deaf subjects showed responses of transition level, which indicates a situation of cognitive delay. We conclude that the potential compromise linguistic presented by deaf people, can hinder the activity representative causing delay in construction of temporal notion and consequently the development of thought. We conclude that the possible linguistic committal presented by deaf people can hinder the representative activity, causing delay in construction of temporal notion and consequently in the development of thought. In this sense, it seems that the Sign Language constitutes an important tool for deaf people because it allows symbolic exchanges that favor the cognitive development.

Aims: the aims of this study were to compare and to characterize the fine, sensory and perceptive function performance and handwritten quality between students with learning difficulties and students with good academic performance. GII, GIII and GIV: 96 students with learning difficulties, and groups GV, GVI, GVII, GVIII: 96 good academic performance. The students were submitted to evaluation of fine motor, sensorial and perception functions and handwriting evaluation under dictation. Results: the results show that the students with learning difficulties from 1st to 3rd grade had lower performance on tests of fine motor, sensory and perceptive function compared to the students with good academic performance in the same grade; the students from 4th grade, both groups, did not show changes on fine motor sensory and perceptive function; and only the students of GII showed disgraphya. Conclusions: the results presented in this study suggest that the qualitative aspects of fine motor, sensory and perceptive skills reflect the integrity and maturity of central nervous system and can probably play an important role in early diagnosis of development disorders and consequently prevent academic disorders such as handwriting performance.
