504 (five hundred four) 1 day old male chicks from a commercial broiler line (Ag Ross 308) were used, distributed in 12 treatments, with 6 replicates per treatment. The experimental design was casually blocked and treatments were organized in a 2x2x3 factorial arrangement: two available phosphorus levels (0.45 and 0.34%), two phytase inclusion levels (0 and 1200 FTU/kg) and three crude protein levels (22.5; 20.5 and 18.5%). Tibia calcium percentage was influenced by protein and phosphorus levels in the diet, when using phytase. Tibia ash levels showed a linear effect when enzymes were added and showed a quadractic effect without it, and the higher value was observed with 22.5% crude protein in the diet. With higher phosphorus levels a linear effect was observed between crude protein in the diet and tibia ash weights, as a higher protein level had lower tíbia ash weight.

The experiment was conducted to evaluate the ingestive behavior of feedlot lambs fed with an exclusive diet of concentrate with different percentages of protein (14, 16, 18, and 20%). A total of twenty four Santa Inês crossbred lambs, not castrated, with approximately 180 days of age, average live weight of 25kg, confined, in a completely randomized design, with four treatments and six repetitions. The time spent on feeding decreased linearly in 0.20 hours/day for each 1% increasing in protein percentage in the diet, the idleness increased linearly in 0.25 hours/day, and the total chewing decreased linearly in 0.25 hours/day. The increase in the protein percentage in the diet increased the feed efficiency linearly (kg DM and NDF/hour) in 0.038 and 0.005kg/hour, respectively, for DM and NDF fractions. However, the intake of dry matter (DM) and neutral detergent fiber (NDF), the rumination efficiency (kg DM and NDF/hour), as well as the period (nº /day) and the time (min) spent on feeding, ruminating and idling were not influenced by different protein percentages in the diet.

PURPOSE: to evaluate and compare the fluency between the familial and the sporadic persistent developmental stuttering, characterizing the typology and the frequency of the disfluencies, the speech rate and the severity of the stuttering. METHOD: 40 participants aged from 6 to 42 years old, divided in two groups with twenty participants in each one: Familial Persistent Developmental Stuttering and Sporadic Persistent Developmental Stuttering. The procedures used were: clinical and familial history, assessment of fluency and Stuttering Severity Instrument. RESULTS: there were no statistically significant differences between the groups regarding the frequency of stuttering like disfluencies, the flow of syllables and words per minute and the severity of stuttering. It was noted a tendency of the group with familial stuttering to show a bigger variability of the severity of stuttering, going from mild to very severe, whereas in the group with sporadic stuttering, the severity varied from mild to severe. CONCLUSION: this study represents the first effort to the characterization of the speech fluency profile of the subgroups of people who stutter, namely familial persistent developmental stuttering and sporadic persistent developmental stuttering. It is possible to conclude that the speech fluency profile of people who stutter, independently of the familial history, is similar. It is noteworthy that the occurrence of some stuttering-like disfluencies, monosyllabic word repetition, block and intrusion were different between groups.

O objetivo deste trabalho foi caracterizar o gene vip3A de Bacillus thuringiensis e verificar a toxicidade da proteína Vip3Aa50 a larvas da lagarta-do-cartucho (Spodoptera frugiperda) e da lagarta-da-soja (Anticarsia gemmatalis). O gene vip3A foi amplificado por PCR, com iniciadores específicos, e gerou um fragmento de 2.370 pb. Esse fragmento foi clonado em vetor pGEM-T Easy e, em seguida, sequenciado, subclonado em vetor de expressão pET-28a (+) e inserido em células de Escherichia coli BL21 (DE3). A expressão da proteína Vip3Aa50 foi induzida por isopropil-β-D-1-tiogalactopiranosídeo (IPTG), visualizada em SDS-PAGE e detectada por Western blot. Os ensaios de toxicidade revelaram alta atividade da proteína Vip3Aa50 contra as larvas neonatas da lagarta-da-soja e da lagarta-do-cartucho, com CL50 de 20,3 e 79,6 ng cm-2, respectivamente. O gene vip3Aa50 é um novo gene da classe vip3A.
