1. Effect of alpha1-blockers on stentless ureteroscopic lithotripsy
ABSTRACT Objective To evaluate the clinical efficiency of alpha1-adrenergic antagonists on stentless ureteroscopic lithotripsy treating uncomplicated lower ureteral stones. Materials and Methods From January 2007 to January 2013, 84 patients who have uncomplicated lower ureteral stones treated by ureteroscopic intracorporeal lithotripsy with the holmium

2. The use of alpha-1 adrenergic blockers in children with distal ureterolithiasis: a systematic review and meta-analysis
Introduction: Urinary lithiasis is the main urologic cause of emergency treatment in adult patient. In the past years, the incidence in children population has increased. However, literature about the use of alpha-1 adrenergic blockers in pediatric population with distal ureterolithiasis is still scarce. The drug acts by decreasing ureter contractions, espe

3. Efeito da tansulosina e do nifedipino na eliminação de fragmentos após litotripsia extracorpórea por ondas de choque em pacientes com cálculos renais: estudo prospectivo, duplo-cego e randomizado / Effect of tamsulosin and nifedipine on the clearance of fragments after extracorporeal shock waves lithotripsy in patients with kidney stones - a prospective, double-blind and randomized study
Purpose: We evaluated the effects of the adjuvant use of tamsulosin and nifedipine after extracorporeal shock wave lithotripsy (SWL) for 5-20 mm kidney stones. Materials and Methods: We conducted a randomized double-blind trial involving 136 patients with radiopaque kidney stones between 2006 and 2009. Patients were divided into three groups to receive daily

5. Efeito da terapia com Beta-bloqueadores em camundongos com deleção dos receptores alpha 2A/alpha 2C adrenérgicos / Effects of b- adrenergic antagonist therapy in mice lacking a 2A/a 2C adrenergic receptors
We have recently reported that disruption for both a2A ?and a2C adrenergic receptor subtypes in mice (KO) leads to sympathetic hyperactivity with evidence of heart failure (HF) by the age of 7 months. These mice provide a model system for evaluating the efficiency among different ?- adrenergic antagonists (BB) for HF therapy. In the present study, we evaluat

6. Adrenergic regulation of the skeletal alpha-actin gene promoter during myocardial cell hypertrophy.
The skeletal alpha-actin gene is expressed in fetal rat heart and is induced during norepinephrine (NE)-stimulated hypertrophy in cultures of neonatal rat cardiac myocytes. Here we report that NE positively regulates the human skeletal alpha-actin gene promoter in transiently transfected neonatal rat cardiac myocytes. NE increased expression from the full-le

7. The Adrenergic Control of Lower Esophageal Sphincter Function: AN EXPERIMENTAL MODEL OF DENERVATION SUPERSENSITIVITY
To evaluate the adrenergic regulation of lower esophageal sphincter (LES) function, LES pressure, LES relaxation during swallowing, and blood pressure were measured in the anesthetized opossum, Didelphis virginiana, during intravenous administration of alpha and beta adrenergic agonists and antagonists. Studies were done in controls and animals adrenergicall

8. Beta 2-adrenergic mechanisms in experimental arthritis.
We have studied (i) the contribution of specific adrenergic receptors to the proinflammatory effects of the sympathetic nervous system in experimental arthritis and (ii) the phases of the disease during which the sympathetic nervous system influences joint injury. Severity of joint injury was measured radiographically 28 days after induction of adjuvant arth

9. A nuclear pathway for alpha 1-adrenergic receptor signaling in cardiac cells.
alpha 1-Adrenergic agonists and antagonists constitute an important class of therapeutic agents commonly used for the treatment of various cardiovascular diseases like hypertension, congestive heart failure and supraventricular tachycardia. At the heart level, activation of alpha 1-adrenergic receptors is associated with marked morphological and genetic chan

10. Adrenergic Modulation of Pancreatic Glucagon Secretion in Man
In order to characterize the influence of the adrenergic system on pancreatic glucagon secretion in man, changes in basal glucagon secretion during infusions of pure alpha and beta adrenergic agonists and their specific antagonists were studied. During infusion of isoproterenol (3 μg/min), a beta adrenergic agonist, plasma glucagon rose from a mean (±SE) b

11. Solubilization of human platelet alpha-adrenergic receptors: evidence that agonist occupancy of the receptor stabilizes receptor--effector interactions.
The alpha-adrenergic receptors of human platelet membranes can be directly identified by both a radiolabeled agonist, [3H]epinephrine, and a radiolabeled antagonist, [3H]yohimbine. Digitonin solubilizes a binding component from the membrane that is indistinguishable from the alpha-receptor identified in the native platelet membrane as assessed by (i) order o

12. Anticoccidial activities of 7-bromo-N-(2-imidazolidinylidene)-1H-indazol-6-amine and other alpha 2 adrenergic agonists.
Activity against the coccidial pathogen Eimeria tenella in chickens has been discovered among alpha 2 adrenergic agonists. The clonidine analog 7-bromo-N-(2-imidazolidinylidene)-1H-indazol-6-amine was active in feed at 7.5 ppm, a concentration similar to the use levels of potent commercial agents, e.g., maduramicin. Additional alpha 2 agonists were also foun
