1. Effects of ropivacaine combined with morphine at 0.15 and 0.2 mg kg-1 in bitches undergoing epidural anesthesia
PURPOSE: To investigate cardiorespiratory effects and serum concentration of ropivacaine combined with morphine at different doses.METHODS: Sixteen healthy adult female dogs weighting 9.8±4.1 kg were included in the study. Twenty minutes after being premedicated with acepromazine and midazolam, the animals were randomly assigned to receive an epidural injec

2. Sedative and clinical effects of the pharmacopuncture with xylazine in dogs
PURPOSE: To investigate the sedative and clinical effects of the pharmacopuncture with xylazine, compared to the conventional dose of a intramuscular injection in dogs. METHODS: Twelve dogs were randomly distributed in two groups of six animals and treated as follows: control group (X-IM): 1mg kg-1 of xylazine given intramuscularly (IM); pharmacopunctu

3. Ontogênese do ritmo de consumo de oxigênio em operárias de Melipona quadrifasciata (Hymenoptera; Meliponini): a influência da luz / Ontogenesis of respiratory rhythms in Melipona quadrifasciata workers: the influence of light
As operárias de Melipona quadrifasciata exercem diferentes funções na colônia, segundo sua faixa etária. No interior da colônia, os indivíduos mais jovens, nutrizes, ficam localizados na região mais interna e aproximam-se progressivamente das regiões periféricas à medida que envelhecem. Os indivíduos mais velhos, forrageiras, saem da colônia dia

4. Avaliação comportamental e fisiológica de suínos em baias individuais e gaiolas metabólicas. / Behavioral and physiological evaluation of swine in individual stalls and metabolic cages.
Two articles were made to assessed the behavioral and physiological parameters of pigs housed in individual stalls and metabolism cages. The first article was to evaluate the effects of period (before and during), type of housing (individual stall and metabolic cage) and feeding treatment (T1, T2, T3 and T4) in salivary cortisol concentrations. Was collected

5. Control of respiration in fish, amphibians and reptiles
Fish and amphibians utilise a suction/force pump to ventilate gills or lungs, with the respiratory muscles innervated by cranial nerves, while reptiles have a thoracic, aspiratory pump innervated by spinal nerves. However, fish can recruit a hypobranchial pump for active jaw occlusion during hypoxia, using feeding muscles innervated by anterior spinal nerves

6. Assistência clínica materna e neonatal às diferentes condições obstétricas em bovinos da raça Holandesa / Maternal and neonatal clinical assistance under distinct obstetrical conditions in Holstein cattle
The novel reproductive biotechnologies (ET, IVF and Cloning) require more accurate control of pregnancy and parturition, due to obstetrical problems as a result of the large offspring syndrome or reduced calf vitality associated with placental anomalies. Hence, the reduction in neonatal mortality is justifiable as research in this area progresses, aiming mat

7. Termorregulação colonial e energética individual em abelhas sem ferrão Melipona quadrifasciata Lepeletier (Hymenoptera, Apidae, Meliponini) / Colonial thermoregulation and energetics in stingless bees Melipona quadrifasciata Lepeletier (Hymenoptera, Apidae, Meliponini).
In eusocial insects, such as stingless bees, the control of nest conditions and maintenance of the colonial microclimate are important to brood incubation, development of eggs, larvae and pupae, and survival of the colony. One of the main thermoregulatory mechanisms to control nest temperature is the microhabitat selection to build the nest, such as tree hol

8. Computerized invasive measurement of time-dependent intraocular pressure
Several methods have been described to measure intraocular pressure (IOP) in clinical and research situations. However, the measurement of time varying IOP with high accuracy, mainly in situations that alter corneal properties, has not been reported until now. The present report describes a computerized system capable of recording the transitory variability

9. "Estudo da ocorrência de acidentes entre trabalhadores de uma indústria frigorífica do Estado de São Paulo" / "A study on the occurrence of accidents among workers at a meat packing industry in the State of São Paulo"
Meat packing work is marked by repetitive activities; intense work rhythm; environments with inadequate levels of illumination, noise and temperature; presence of dust; small spaces and frequent handling of cutting instruments. These characteristics make this activity exhausting and dangerous and, hence, an interesting object of study, but is socially releva

10. EPIDURAL CLONIDINE OR SUFENTANIL IN DOGS UNDERGOING OVARIO-HISTERECTOMY / CLONIDINA OU SUFENTANIL EPIDURAL EM CÃES SUBMETIDOS À OVÁRIO-HISTERECTOMIA
The objective of this study was to evaluate the cardiovascular, respiratory and analgesic effects of epidural clonidine and sufentanil associated with halothane anesthesia and in the immediate postoperative period. In order to study this, twenty female dogs, healthy, among 10 to 20 kg from the routine of Veterinary Hospital of UFSM underwent ovario-histerect

11. Can the Cardiopulmonary 6-Minute Walk Test Reproduce the Usual Activities of Patients with Heart Failure?
OBJECTIVE: The 6-minute walk test is an way of assessing exercise capacity and predicting survival in heart failure. The 6-minute walk test was suggested to be similar to that of daily activities. We investigated the effect of motivation during the 6-minute walk test in heart failure. METHODS: We studied 12 males, age 45±12 years, ejection fraction 23±7%,

12. Desenvolvimento de sistemas bio-telemétricos para a medida da freqüencia cardíaca e do ritmo respiratório. / Development of Biotelemetric systems for the measure of the cardiac frequency and the respiratory rhythm.
O desenvolvimento da Física tem possibilitado sua atuação em vários campos, e mais recentemente, na Medicina, onde estudos da Freqüência Cardíaca e do Ritmo Respiratório fornecem informações importantes acerca de processos fisiológicos e podem ser um útil instrumento diagnóstico e terapêutico. Nestes estudos, em muitos casos, necessita-se que a
