Regulação da temperatura corporal em diferentes estados térmicos: ênfase na anapirexia

Temperature is certainly one of the major factors that affect biochemical and physiological processes. So, the investigation of how animals regulate body temperature (Tb) and respond to changes in ambient temperature is indispensable. There are five thermal states defined up to date that include euthermy, hypo and hyperthermia (forced fall and increase of Tb, respectively), fever and anapyrexia (regulated increase and fall of Tb, respectively). In this review, we present some classic and recent data about thermoregulatory mechanisms involved in those thermal states with special attention directed to anapyrexia, a phenomenon that has attracted the interest of researchers due to its potential therapeutic benefits.

A noção de esquema corporal na filosofia de Merleau-Ponty: análises em torno da 'Fenomenologia da Percepção'

The Throughout the work of Merleau-Ponty, besides philosophical concepts and images of his thinking, some theoretical-anthropological devices exist that reveal his approximation of human sciences. That is the case of the notion of body schema. Interested in discussing the role the critical development of this concept may have played in the passage from the first phase of his work to the period when the philosopher finds himself able to outline a new ontology, in this paper, we study the presence of the body schema notion in the Phenomenology of perception. We show that, in this book, Merleau-Ponty unsubstantiates the notion under analysis which, from a cognitive core that organizes our bodily experience, turns into the expression of our body parts’ mutual permeability, but also of the body’s permeability towards the world and other people.

Manejo pré-abate de ovelhas de descarte: perdas de peso corporal, qualidade da carne e comportamento animal

The aim of this study was to know the behavior of Santa Inês ewes in different physiological stages during the pre-slaughter management, as well as their body weight loss, blood hematocrit values and meat quality. 21 discard ewes were used, arranged into the following treatments: T1 = ewes which remained in lactation for 60 days with their respective lambs and slaughtered one day after weaning; T2 = ewes which remained in lactation for 60 days with their respective lambs and one more period of approximately 30 days without the lambs and afterwards slaughtered; and T3 = ewes which remained in confinement for 60 days and did not give birth during the year. The weight of ewes after transportation was lower for T1 in comparison with T2. Blood hematocrit values of ewes before and after transportation and after fast in the waiting pen were not different among the treatments, with mean value of 58.50%. We concluded that the quality of meat of discard ewes in different physiological stages is not altered by pre-slaughter management, when correctly performed (avoiding animal stress), concerning meat pH.

Movimento dos olhos e controle postural

The control of stances such as the upright stance seems not to have a purpose in itself; this control could facilitate the execution of other simultaneous tasks, the so-called suprapostural tasks. The goal of this study was to determine the effects of saccadic eye movements on the control of posture. Twelve adult participants had their body oscillations analyzed while standing upright, for 70 s, in the postural conditions of feet apart and feet together, performing fixation in the central target or horizontal saccadic movements, in the conditions slow (0,5 Hz) and fast (1,1 Hz). The results showed that saccadic movements, independently of their frequency, strongly reduced trunk and head oscillations in the anterior-posterior (AP) axis. In this axis, there was an effect of feet position only in head oscillation. In the medio-lateral (ML) axis, the results showed a strong effect of feet position with body oscillation decreased in the condition of feet apart. The effect of the visual task in the ML axis occurred only for trunk oscillation, not reaching significance level in the pairewise comparisons. In the AP axis, the data corroborate a facilitatory explanation of the control of posture: the reduction in body oscillation limited the variations of the stimulus image projected on the retina, facilitating the execution of saccadic movements as compared to fixation. In the ML axis, the effect of reducing the basis of support was more evident than the effect of saccadic movements, suggesting that the available resources were used primarily for the postural task in detriment of the visual task. Additionally, aspects like attentional focus and sensory information pick up are discussed as mechanisms involved in this task

Aquisição da informação visual: controle da postura e do olhar

Postural control is needed to perform various daily activities, from staying in one posture, standing, to sports situations. Many studies have shown that sensory systems help to maintain posture stable; acquisition of perceptual information, particularly through head and eye movements, allows static and dynamic equilibrium. Research related to both motor behavior and physical activities such as gymnastics have contributed to a better understanding of complexities involved in human postural control. The purpose of this study was to review the related literature, searching for possible answers on how everyday and sports actions are performed, with respect to the control and maintenance of posture. Its focus was on how the human body acquires information from the sensory systems, vision in special, and how this information acts to support the control of posture and gaze

Características morfométricas e rendimento corporal do suruvi Steindachneridion scriptum agrupados por sexo

The body shape, body yields and morphometric ratios is important for species characterization and evaluation of their productive potential. The aim of this study was to determine the morphometric reasons, the body yields and correlations for male and female suruvi, Steindachneridion scriptum. Was analyzed 30 males and 30 females, and length and weight measurements were made. Was calculated carcass yields and morphometric relationships. The design was complete randomized. Data were subjected to analysis of normality; variance and means were compared by t test and Mann Whitney test. The average total weight of males was 1,583.50 +/- 263.79 g, while the total weight of females was 1,606.66 +/- 185.34 g. The total lengths were 53.42 +/- 2.64 cm for males and 53.35 +/- 1.98 cm for females. Average total weight and total lengths was similar between the sexes (P>0.05). Dress out yields of 65.54 +/- 1.36% (males) and 65.71 +/- 1.20% (females) and edible portions of 41.99 +/- 1.66% (males) and 41.93 +/- 2.05% (females) did not differ significantly between the sexes (P>0.05). The percentage of head relative to the total weight was significantly higher in males (17.67 +/- 1.24%) than in females (16.90 +/- 0.85%). The weight of the viscera such as the percentage relative to the total weight was significantly higher in females. The species has no body yields and morphometric characteristics limitations for commercial production.

A complexidade de tarefas de controle postural afeta a sensibilidade háptica proporcionada pelo toque leve?

A utilização de pistas hápticas para a estabilização da postura através do toque vem sendo apontada como uma eficiente fonte de informação sensorial que conecta o indivíduo ao meio. Dessa forma, o paradigma do toque leve (i.e., tocar uma superfície com força inferior a 1 Newton) é uma das possibilidades de, através do contato com determinada superfície, atenuar as oscilações do indivíduo. Sendo assim, o objetivo deste estudo foi verificar a eficiência do toque leve em tarefas de alta complexidade ao equilíbrio e, concomitantemente, analisar a relação entre percepção háptica e controle da postura. Para isso, 15 adultos jovens saudáveis participaram deste estudo, permanecendo em pé na posição tandem sobre uma plataforma de força e-nas condições pertinentes-sobre uma trave de equilíbrio. As condições deste estudo variaram entre a utilização ou não do toque, a utilização ou não da visão, e ainda, permanecer em pé sobre uma superfície de altura normal (0 cm) ou uma superfície com elevação (20 cm). Através da análise estatística avaliamos as variáveis amplitude média de oscilação (ântero-posterior e mediolateral), velocidade média (ântero-posterior e medio-lateral) e a trajetória total. Nossos resultados demonstraram, como já era esperado, um aumento significativo da oscilação corporal nas condições sem toque e sem a utilização da visão, e ainda maior quando houve elevação da superfície de apoio dos pés. Entretanto, quando o toque leve foi utilizado nessas mesmas condições houve uma redução significativa da oscilação postural dos indivíduos. Dessa forma, concluímos que mesmo em tarefas de alta instabilidade ao equilíbrio, o toque leve continua auxiliando no controle da postura
