Entre bois e cabras: uma visão histórica sobre mentalidades e valores nos sertões

A culture of resistance in the semi-arid, expressed by mentalities and values, goes against the economic potential of sheep and goat raising, considered as an inferior activity when compared to the cattle raising, historically linked to social status and prestige. This paper attempts to shed light on aspects that make possible to clarify the roots of the cognitive apparatus that supports this view, resorting to it to the production of relevant authors dealing with the issue of displacement of colonizer and livestock in the hinterlands. Ultimately, it seeks evidence of the influence of the historical process of economic and social organization of space on the present.

Avaliação do índice de Litle em indivíduos que utilizaram o aparelho funcional T4K

The study aimed to assess the degree of dental crowding correction on the lower anterior region of patients treated with T4k functional appliance using Little’s irregularity index. Twenty caucasian patients of both gender (10 female and 10 male) were selected. They featured malocclusion Class I and II in mixed dentition, with chronological age between 5.7 and 11 years. The treatment lasted from 1 year and 11 months up to 3 years and 11 months. Lower anterior crowding was measured using Little’s irregularity index. Measurements were obtained on study models achieved before and after functional orthopedic therapy, using a digital caliper in millimeters and placed parallel to the occlusal plane. Overjet and overbite measurements were also performed using a caliper. Results demonstrated that the therapy provided significant decrease in overjet (average = 1.55 mm) and also in the irregularity index (average = 1.23 mm). There was a nonsignificant raise in overbite. There was no relation between the studied variables and the treatment period or even with the patient’s age in the beginning of the therapy. The treatment with T4k resulted on reduction and improvement of dental crowding.

Eficiência do aparelho Herbst bandado na correção da Classe II divisão 1 -relato de caso

The current reports the case of a young patient with malocclusion Class II division 1 on permanent dentition treated in two stages, rthopedics and orthodontics, respectively. At first, the banded Herbst appliance was used duringa 7 months period, followed by a T4K appliance, Trainer for Kids used as retention, and on the second stage the corrective Orthodontics was performed. The results showed the acquirement of a Class I dental relationship, which was kept stable, with excellent intercuspation, even after 5 years of the removal of the Herbst appliance, as well as the correction of the overjet and the reduction of the facial profile convexity. It can be concluded that the Herbst appliance was very efficient in correcting the Class II malocclusion, long term, also providing a very favorable effect on the facial profile.

State of the art on animal embryonic chimeras

Embryonic chimerism is generally used in basic research and in vivo diagnosis of undifferentiated embryonic stem cells (ESC), mostly using mice embryos, although there have been reports in the literature on using rat, rabbit, sheep, chicken, primate, bovine, goat and pig embryos. Several techniques can currently be used to produce chimeric embryos, including microinjection, co-culture with ESC, fusion and aggregation. Although microinjection is the most commonly used method in mice, the mere aggregation of embryos with ESC may result in viable chimeras and be as efficient as microinjection. In mice, this chimerism technique has been shown to have the advantage of aggregating embryos in different stages of development with different ploidy, in addition to using ESC in the tetraploid complementation assay. Compared to other techniques for producing chimeras, the aggregation technique is a cheaper, faster and easier methodology to be performed. Moreover, aggregation can be simplified by chemically removing the zona pellucida with pronase or acidic Tyrode’s solution and be enhanced by using the Well of the Well culture system in combination with adhesion molecules, such as phytohemagglutinin. The most commonly used stages for chimerism by aggregation are those that precede the full compaction of the morula. In these stages, embryos have low-tension adherent junctions at the tangential point between two blastomeres. During the embryonic development of mice, the inner cell mass differentiates into epiblast and hypoblast. These layers will originate the fetal tissues and a portion of the extraembryonic tissues (yolk sac, allantois and amnion), whereas the trophectoderm (TE) gives rise to the chorion. A functional TE is essential for the complex molecular communications that occur between the embryo and the uterus. Embryos produced by somatic cell nuclear transfer, such as commercial cattle clones or endangered species, are subject to large fetal and neonatal losses. Hence embryo complementation with heterologous TE could be of assistance to decrease these losses and might as well assist development of high-value embryos in other approaches.

Brinquedoteca móvel: o brincar interativo na hospitalização infantil

The hospitalization process can cause significant changes in the children’s everyday life because, besides the suffering caused by the disease, there are the invasive processes which bring them sorrow. Thus, aiming to make this state of sorrow lower and to contribute for the treatment process we developed in a hospital the Mobile Toy Library project which develops interactive activities through playing, trying to make the staying of these kids at the hospital easier. The team is formed by Psychology professors and students, who daily visit the children with a trolley full of toys in order to interact and play with them. We wait on 500 patients a year. We concluded the Mobile Toy Library provides ways for kids to elaborate their psychological conflicts, lowering their sorrow as well as their negative feelings of staying in hospital, and this helps them deal with the disease, family and medical team all together.

Thermoregulatory responses of goats in hot environments

Notwithstanding the solar radiation is recognized as a detrimental factor to the thermal balance and responses of animals on the range in tropical conditions, studies on the amount of thermal radiation absorbed by goats therein associated with data on their production and heat exchange are still lacking. Metabolic heat production and the heat exchange of goats in the sun and in the shade were measured simultaneously, aiming to observe its thermal equilibrium. The results showed that black goats absorb twice as much as the white goats under intense solar radiation (higher than 800 W m(-2)). This observation leads to a higher surface temperature of black goats, but it must not be seen as a disadvantage, because they increase their sensible heat flow in the coat-air interface, especially the convection heat flow at high wind speeds. In the shade, no difference between the coat colours was observed and both presented a lower absorption of heat and a lower sensible heat flow gain. When solar radiation levels increases from 300 to 1000 W m(-2), we observed an increase of the heat losses through latent flow in both respiratory and cutaneous surface. Cutaneous evaporation was responsible for almost 90 % of the latent heat losses, independently of the coat colour. Goats decrease the metabolic heat production under solar radiation levels up to 800 W m(-2), and increase in levels higher than this, because there is an increase of the respiratory rate and of the respiratory flow, but the fractions of consumed oxygen and produced carbon dioxide are maintained stable. The respiratory rate of black goats was higher than the white ones, under 300 W m(-2) (55 and 45 resp min(-1)) and 1000 W m(-2) (120 and 95 resp min(-1), respectively). It was concluded that shade or any protection against solar radiation levels above 800 Wm(-2) is critical to guarantee goat's thermal equilibrium. Strategies concerning the grazing period in accordance with the time of the day alone are not appropriate, because the levels of radiation depend on the latitude of the location.

Energy requirements for growth of pubertal female Saanen goats

Previous research on energy requirements of female Saanen goats, using the factorial approach, has not considered the specific requirements for maintenance and growth during the pubertal phase. Thus, the purpose of this study was to estimate energy requirements for maintenance (Trial 1) and growth (Trial 2) of non-pregnant and non-lactating female Saanen goats at the pubertal phase from 30 to 45 kg. In Trial 1, the net energy requirements for maintenance (NEm ) were estimated using 18 female Saanen goats randomly assigned to three levels of intake: ad libitum, and 70% and 40% of ad libitum intake. These animals were pair-fed in six slaughter groups, each consisting of one animal for each level of intake. In Trial 2, the net energy requirements for growth (NEg ) were estimated using 18 female Saanen goats, which were fed ad libitum and slaughtered at targeted BW of 30, 38 and 45 kg. The NEm was 52 kcal/kg(0.75) of BW. The NEg increased from 3.5 to 4.7 Mcal/kg of BW gain as BW increased from 30 to 45 kg. Our results suggest that the guidelines of the major feeding systems for the entire growth phase may not be adequate for females at pubertal phase.

Digital venography in ruminants - a review

Digital venography is a contrast angiography technique used to study digital vascularity. The technique is simple to be carried out and can be performed under field conditions using a standard radiographic unit. The venogram examination is used to complement conventional radiographic examinations in animals affected by foot diseases. Discrepancy in the contrast vascular pattern may be observed before the clinical signs of the foot disease. Digital venography studies in ruminants are in smaller number than those in horses. The herein presented review discusses digital venography techniques used in ruminants as well as the differences and similarities between ruminants (cattle, sheep and goat) and horses.
