1. Cannabidiol presents an inverted U-shaped dose-response curve in a simulated public speaking test
Objective: Cannabidiol (CBD), one of the non-psychotomimetic compounds of Cannabis sativa, causes anxiolytic-like effects in animals, with typical bell-shaped dose-response curves. No study, however, has investigated whether increasing doses of this drug would also cause similar curves in humans. The objective of this study was to compare the acute effects

2. The modular nature of bradykinin-potentiating peptides isolated from snake venoms
Abstract Bradykinin-potentiating peptides (BPPs) are molecules discovered by Sergio Ferreira – who found them in the venom of Bothrops jararaca in the 1960s – that literally potentiate the action of bradykinin in vivo by, allegedly, inhibiting the angiotensin-converting enzymes. After administration, the global physiological effect of BPP is the decrease

3. Evaluation of hemodynamic effects of xenon in dogs undergoing hemorrhagic shock
OBJECTIVES: The anesthetic gas xenon is reported to preserve hemodynamic stability during general anesthesia. However, the effects of the gas during shock are unclear. The objective of this study was to evaluate the effect of Xe on hemodynamic stability and tissue perfusion in a canine model of hemorrhagic shock. METHOD: Twenty-six dogs, mechanically ventila

4. Avaliação da atividade neuroprotetora da Parawixina 11 isolada da peçonha da aranha Parawixia bistriata (Araneae, Araneidae), em ratos Wistar submetidos a um modelo de glaucoma agudo / Neuroprotective activity analysis of Parawixin 11, isolated from Parawixia bistriata (Araneae, Araneidae) spider venom, in Wistar rats submitted to an model of acute glaucoma
Glaucoma is defined as a typical optic neuropathy characterized by ganglion cells loss and consequent optic nerve damage, resulting in a gradual reduction of the visual field and eventual blindness. In regard to compounds present in spider venoms, they represent an interesting source of bioactive molecules and the study about the possible neuroprotective eff

5. Monosodium glutamate neonatal treatment induces cardiovascular autonomic function changes in rodents
OBJECTIVES: The aim of this study was to evaluate cardiovascular autonomic function in a rodent obesity model induced by monosodium glutamate injections during the first seven days of life. METHOD: The animals were assigned to control (control, n = 10) and monosodium glutamate (monosodium glutamate, n = 13) groups. Thirty-three weeks after birth, arterial an

6. Cardiovascular effects of the intracerebroventricular injection of adrenomedullin: roles of the peripheral vasopressin and central cholinergic systems
Our objective was to investigate in conscious Sprague-Dawley (6-8 weeks, 250-300 g) female rats (N = 7 in each group) the effects of intracerebroventricularly (icv) injected adrenomedullin (ADM) on blood pressure and heart rate (HR), and to determine if ADM and calcitonin gene-related peptide (CGRP) receptors, peripheral V1 receptors or the central cholinerg

7. Pharmacotherapy for mild hypertension
BACKGROUND: People with no previous cardiovascular events or cardiovascular disease represent a primary prevention population. The benefits and harms of treating mild hypertension in primary prevention patients are not known at present. This review examines the existing randomized controlled trial (RCT) evidence. OBJECTIVE: Primary objective: To quantify the

8. A comparison between diuretics and angiotensinreceptor blocker agents in patients with stage I hypertension (PREVER-treatment trial) : study protocol for a randomized double-blind controlled trial
Background: Cardiovascular disease is the leading cause of death in Brazil, and hypertension is its major risk factor. The benefit of its drug treatment to prevent major cardiovascular events was consistently demonstrated. Angiotensin-receptor blockers (ARB) have been the preferential drugs in the management of hypertension worldwide, despite the absence of

9. Blockade of the action of nitric oxide in human septic shock increases systemic vascular resistance and has detrimental effects on pulmonary function after a short infusion of methylene blue
To investigate the role of nitric oxide in human sepsis, ten patients with severe septic shock requiring vasoactive drug therapy and mechanical ventilation were enrolled in a prospective, open, non-randomized clinical trial to study the acute effects of methylene blue, an inhibitor of guanylate cyclase. Hemodynamic and metabolic variables were measured befor

10. Selective cyclooxygenase-2 inhibition protects against myocardial damage in experimental acute ischemia
BACKGROUND: Acute myocardial infarction is associated with tissue inflammation. Early coronary reperfusion clearly improves the outcome but may help propagate the inflammatory response and enhance tissue damage. Cyclooxygenase-2 is an enzyme that catalyzes the initial step in the formation of inflammatory prostaglandins from arachidonic acid. Cyclooxygenase-

12. Monitorização terapêutica da olanzapina em pacientes esquizofrênicos / Therapeutic monitoring of olanzapina in schizophrenic patients
The olanzapine is an atypical antipsychotic drug used to treat schizophrenia. How adverse effects related to its use, are obesity, hyperlipidemia, diabetes mellitus type II and hypertension, may result in the development of metabolic syndrome. This study aims to carry out monitoring therapy in patients in treatment with olanzapine, establishing a possible co
