1. EVENTS ASSOCIATED WITH THE OCCURRENCE OF INTRACRANIAL HYPERTENSION IN PEDIATRIC PATIENTS WITH SEVERE CRANIOENCEPHALIC TRAUMA AND MONITORING OF INTRACRANIAL PRESSURE
RESUMO Objetivo: Determinar eventos associados à ocorrência de hipertensão intracraniana (HIC) em pacientes pediátricos com traumatismo cranioencefálico grave. Métodos: Trata-se de coorte prospectiva de pacientes de até 18 anos, com traumatismo cranioencefálico, pontuação abaixo de nove na Escala de Coma de Glasgow e monitoração da pressão int

3. A fatal and metabolic experimental hemorrhagic shock in immature swine
Abstract Purpose: To use blood lactate (BL) as an end-point metabolic marker for the begin resuscitation of volume replacement in experimental hemorrhagic shock. Methods: Group I (n=7) was not bled (Control). Animals in Group II (n=7) were bled to a MAP of 30mmHg in thirty minutes. Hemodynamic and metabolic data were recorded at Baseline, at 30, 60 and 1

4. Acute but not chronic metabolic acidosis potentiates the acetylcholine-induced reduction in blood pressure: an endothelium-dependent effect
Metabolic acidosis has profound effects on vascular tone. This study investigated the in vivo effects of acute metabolic acidosis (AMA) and chronic metabolic acidosis (CMA) on hemodynamic parameters and endothelial function. CMA was induced by ad libitum intake of 1% NH4Cl for 7 days, and AMA was induced by a 3-h infusion of 6 M NH4Cl (1 mL/kg, diluted 1:10)

5. Central Vestibular Dysfunction in an Otorhinolaryngological Vestibular Unit: Incidence and Diagnostic Strategy
Introduction Vertigo can be due to a variety of central and peripheral causes. The relative incidence of central causes is underestimated. This may have an important impact of the patients' management and prognosis. Objective The objective of this work is to determine the incidence of central vestibular disorders in patients presenting to a vestibular uni

6. Cortical activity in tinnitus patients and its modification by phonostimulation
OBJECTIVE: The goal of this study was to observe spontaneous cortical activity and cortical activity modulated by tinnitus-matched sound in tinnitus patients and healthy subjects with no otoneurologic symptoms. METHOD: Data were prospectively collected from 50 tinnitus patients and 25 healthy subjects. Cortical activity was recorded in all subjects with e

8. Hyperventilation accelerates the rise of arterial blood concentrations of desflurane in gynecologic patients
OBJECTIVES: Under a constant inspired concentration, the uptake of a volatile anesthetic into the arterial blood should mainly be governed by alveolar ventilation, according to the assumption that the patient's cardiac output remains stable during anesthesia. We investigated whether ventilation volume affects the rate of desflurane uptake by examining arteri

9. Efeitos do Roundup™ e do Thiodan em adultos de Astyanax bimaculatus (Characidae: Teleostei): Valores de CL50 e morfologia testicular / Effects of Roundup™ and the Thiodan in adults of Astyanax bimaculatus (Characidae: Teleostei): Values of CL50 and testicular morphology
The indiscriminated use of agrochemicals in modern agriculture is unleashing a series of damages to the environment posing serious threats to the survival of important ecosystems. The main objectives of the present study was to determine the LC50-96h and investigate the effects of Roundup™ (Monsanto) and Thiodan (Bayer) in testicular morphology of the

10. Participação dos núcleos da rafe nas respostas cardiorespiratórias à hipóxia e hipercarbia em sapos / Role of the raphe nuclei in the ventilatory and cardiovascular response to hypoxia and hipercarbia in toads
The raphe nuclei are brainstem cell groups and the main cell type is serotonergic. In adult anurans electrical or chemical stimulation of the medullary raphe has no effect on ventilation, whereas in mammals depending on the specific site of stimulation, an excitatory or inhibitory response is elicited. In mammals the medullary raphe participate in the ventil

11. Associação entre transtorno de pânico, asma e outras doenças obstrutivas pulmonares / Association between panic disorder, asthma and other pulmonary obstructive disorders
A ocorrência do transtorno do pânico com asma e outras doenças obstrutivas pulmonares é maior que o esperado, baseando-se em suas prevalências individuais. Entre pacientes com transtorno do pânico, a presença de hiperventilação, os efeitos panicogênicos do dióxido de carbono e a alta freqüência de queixas relacionadas à respiração evidenciam

12. Respostas cardiorrespiratórias do teleósteo de respiração aérea, Clarias gariepinus, exposto à hipóxia gradual
Peixes de respiração aérea são classificados como respiradores aéreos obrigatórios (aqueles que respiram ar atmosférico independente das tensões de O2 da água) ou facultativos (aqueles que usam o órgão de respiração aérea ABO quando as brânquias não conseguem extrair a quantidade de O2 necessário para manter o metabolismo aeróbico em condi�
