2. Effect of salbutamol on the cardiovascular response in healthy subjects at rest, during physical exercise, and in recovery phase: a randomized, double-blind, crossover study
ABSTRACT Aim To evaluate the effect of the short-acting beta agonists (SABAs) salbutamol on cardiovascular response rest, exercise and recovery phase. Methods This study was conducted as a randomized, double-blind, placebo controlled, crossover study in 15 healthy adults, with a mean age of 30.2±6.6 years. Participants underwent a maximal effort test on t

3. Antagonistas muscarínicos de longa duração vs. β 2 -agonistas de longa duração em exacerbações da DPOC: revisão sistemática e meta-análise
RESUMO Objetivo: Determinar se long-acting muscarinic antagonists (LAMAs, antagonistas muscarínicos de longa duração) são superiores a long-acting β2 agonists (LABAs, β2-agonistas de longa duração) na prevenção de exacerbações da DPOC. Métodos: Revisão sistemática e meta-análise de ensaios clínicos controlados aleatórios com pacientes com

4. Role of adenylyl cyclase in reduced β-adrenoceptor-mediated vasorelaxation during maturation
Beta-adrenergic receptor (βAR)-dependent blood vessel relaxation is impaired in older animals and G protein activation has been suggested as the causative mechanism. Here, we investigated the role of βAR subtypes (β1AR, β2AR, and β3AR) and cAMP in maturation-dependent vasorelaxation impairment. Aortic rings from 15 Sprague-Dawley male rats (3 or 9 weeks

5. Overactive bladder – 18 years – part I
ABSTRACT Abstract: Overactive bladder syndrome is one of the lower urinary tract dysfunctions with the highest number of scientific publications over the past two decades. This shows the growing interest in better understanding this syndrome, which gathers symptoms of urinary urgency and increased daytime and nighttime voiding frequency, with or without urin

6. Overactive bladder – 18 years – Part II
ABSTRACT Traditionally, the treatment of overactive bladder syndrome has been based on the use of oral medications with the purpose of reestablishing the detrusor stability. The recent better understanding of the urothelial physiology fostered conceptual changes, and the oral anticholinergics – pillars of the overactive bladder pharmacotherapy – started

7. Etiological diagnosis reduces the use of antibiotics in infants with bronchiolitis
OBJECTIVE: Acute bronchiolitis is a leading cause of infant hospitalization and is most commonly caused by respiratory syncytial virus. Etiological tests are not required for its diagnosis, but the influence of viral screening on the therapeutic approach for acute bronchiolitis remains unclear. METHODS: A historical cohort was performed to assess the impact

8. Níveis de ractopamina nas dietas de suínos machos castrados na fase de terminação / Ractopamine levels in diet for finishing borrows
The swine production in Brazil has become in recente years, a highly dynamic activity, because the consumer is getting increasingly demanding especially with rescpet to the product it consumes. This fact, coupled with the need for the producer to remain in business, have meant that people involved in the chain pig were in constant learning and the search for

9. Inter-observer agreement in interpreting chest X-rays on children with acute lower respiratory tract infections and concurrent wheezing
CONTEXT AND OBJECTIVE: Many children with acute lower respiratory tract infections (ALRI) present to the emergency ward with concurrent wheezing. A chest x-ray is often requested to rule out pneumonia. We assessed inter-observer agreement in interpreting x-rays on such children. DESIGNS AND SETTING: Prospective consecutive case study at Instituto de Salud de

10. Effect of salbutamol on pulmonary responsiveness in chronic pulmonary allergic inflammation in guinea pigs
Beta-2-agonists have been widely used by asthmatic subjects to relieve their obstructive symptoms. However, there are reports that continuous use could lead to loss of bronchial protection and exacerbation of asthma symptoms. We evaluated the effect of two regimens of salbutamol administration (twice and five times a week) in a model of chronic airway inflam

11. Receptores de glicocorticoides e subtipos de adrenoceptores beta em atrio direito de ratos submetidos a estresse
Right atria of male or female rats sacrificed at diestrus and submitted to foot shock stress show supersensitivity to non-selective and selective Bz-adrenoceptor agonists. This supersensitivity was due to increased Bz-adrenoceptor protein level expression. This tissue also showed subsensitivity to non selective Bl-adrenoceptor agonist, but no changes in BI a

12. Sensibilidade a agonistas [beta]-adrenergicos em atrio esquerdo isolado de ratos submetidos a estresse
Following foot shock stress white adipocytes and right atria from male and right atria from female rats sacrificed at diestrous, are supersensitive to the chronotropic effect of isoprenaline. Right atria from female rats are also subsensitive to noradrenaline. In the present study, we investigated whether the inotropic response to B-adrenergic agonists was a
