1. Comparison between intravenous and intrathecal clonidine for postoperative analgesia of patients submitted to laparoscopic cholecystectomy: randomized clinical trial
Abstract Introduction and objectives: Alpha2 adrenergic agonists, such as clonidine, are used as adjuvants during anesthesia due to their analgesic, sedative, and cardiovascular effects. The objective of the present study was to compare the effect of clonidine administered intravenously and intrathecally on the postoperative pain score of patients undergoin

2. Bronchodilator test in extreme old age: Adverse effects of short-acting beta-2 adrenergic agonists with clinical repercussion and bronchodilator response
RESUMO OBJETIVOS: Avaliar se idade cronológica é um fator limitante para realizar prova broncodilatadora, determinar efeitos adversos significativos com repercussão clínica dos beta-2 agonistas de curta ação e avaliar a resposta broncodilatadora na espirometria, na velhice extrema. MÉTODOS: Estudo transversal, retrospectivo. Amostra extraída do ban

3. 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

4. Extracorporeal transient distal penile corporoglanular shunt in early ischemic priapism treatment
Purpose Ischemic priapism, which is a compartment syndrome, needs urgent treatment in order to nourish corpora cavernosa. As the first step, the aspiration of blood and/or the irrigation of the cavernosal bodies are performed to prevent fibrotic activity and secure erectile capability. While performing aspiration and irrigation, there are some risks of the

5. Avaliação de parâmetros hemogasométricos e bioquímicos durante infusão contínua de detomidina em equinos em estação
A detomidina é um agonistas ¿2 adrenérgicos amplamente empregado para sedação, analgesia e medicação pré-anestésica em equinos. A ativação dos receptores ¿2 distribuídos no Sistema Nervoso Central e Periférico provoca uma série de alterações fisiológicas, tais como bradicardia, bloqueio átrio-ventricular, diminuição do débito cardíaco,

6. The inhibitory role of sympathetic nervous system in the Ca2+-dependent proteolysis of skeletal muscle
Mammalian cells contain several proteolytic systems to carry out the degradative processes and complex regulatory mechanisms to prevent excessive protein breakdown. Among these systems, the Ca2+-activated proteolytic system involves the cysteine proteases denoted calpains, and their inhibitor, calpastatin. Despite the rapid progress in molecular research on

7. Estudo comparativo do uso de Medetomidina e Xilazina em gatos e sua reversão com Atipamezole / Comparative study of the use of Medetomidine and Xilazine in cats and its reversion with Atipamezole
The medetomidine is sedative and analgesic of the group of the a2 adrenergic agonist approved for dogs and cats, described now as more potent than the xylazine, an old agonist a2 adrenergic of veterinary use. The main difference among those two agonists is the selectivity to the receptors a2-adrenergics, being the medetomidine considered more selective, chec

8. Fenoterol e Salbutamol via inalatória em cães: aspectos clínico, laboratorial e eletrocardiográfico / Fenoterol and Salbutamol inalatory road in dogs: clinical, laboratorial and eletrocardiograpy aspects
Salbutamol and fenoterol are agonists β2 adrenergic of short duration, with important paper in the treatment of the breathing diseases due to excellent effect bronchodilator. The study had as objective evaluates through physical exam, laboratorial and electrocardiography the effects of the fenoterol and salbutamol for road inalatory in dogs. Twelve dogs

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. Infusão contínua de xilazina ou dexmedetomidina em cadelas pré-tratadas ou não com atropina: alterações eletrocardiográficas.
Alpha-adrenergic agonist drugs were synthesized at the beginning of the sixties. These drugs cause analgesic, sedative, ansiolitic and simpatholitics effects. Their use is extensive in veterinary due to their sedative, analgesic and miorrelaxantes effects. Alpha-adrenergic agonists cause significant changes in the cardiopulmonary system.

11. Participação dos receptores adrenérgicos Alfa2 do núcleo parabraquial lateral no controle da ingestão de sódio.
Water and NaCl intake is strongly inhibited by the activation of α2-adrenergic receptors with clonidine or moxonidine (α2-adrenergic/imidazoline agonists) injected peripherally or into the forebrain and by serotonin and cholecystokinin into the lateral parabrachial nucleus (LPBN), a pontine structure. Serotonergic and cathecolaminergic neurons are

12. Influencia do ultra-som na permeação cutanea da cafeina : estudo em fragmentos de pele e em adipocitos isolados de suinos
The ultrasound has been extensively used in the last decades for physical therapies and as promoter of cutaneous permeation of drugs. The use of ultrasound as facilitator of cutaneous absorption is knows for phonophoresis or sonophoresis. The aim of present research were to analyze the effect of ultrasound on the cutaneous permeation of caffeine applied loca
