Acetylcholine produces contractions mediated by the cyclooxygenase pathway in arterial vessels in the Chilean frog (Calyptocephalella gayi)

Braz. j. biol; 77 (4), 2017
Abstract Previous studies performed in marine fish (I. conceptionis and G. laevifrons) showed that indomethacin blocked arterial contraction mediated by acetylcholine (ACh). The objective of this study was to determine if contraction induced by acetylcholine is mediated by the cyclooxygenase pathway in s...

Antiretroviral therapy and arterial elasticity in HIV-infected patients

Medicina (B.Aires); 77 (5), 2017
Cardiovascular risk is increased in HIV-infected patients and has become a leading cause of morbimortality in this population. The purpose of this study is to compare HIV-infected patients on antiretroviral therapy (ART) and ART-naïve HIV-infected patients regarding arterial elasticity. From September 2...

Topography of the middle genicular artery is associated with the superior and inferior genicular arteries

Int. j. morphol; 35 (3), 2017
Total knee arthroplasty has increased substantially, however anatomical studies of the genicular arteries (GAs) in this region are rare. The aim of this study was to identify the pattern and branching points of GAs and their relationship. In 42 lower limbs, the pattern and branching points of GAs were co...

Sonographic Findings of the Bifid Median Nerve and Persistent Median Artery in Carpal Tunnel: A Preliminary Study in Chinese Individuals

Clinics; 72 (6), 2017
OBJECTIVE: The aim of this study was to investigate the prevalence of anatomic variations of the bifid median nerve, persistent median artery and persistent median vein in Chinese individuals and their relationship with carpal tunnel syndrome. METHODS: One hundred and sixty median nerves were examined u...

Life-saving vascular access in vascular capital exhaustion: single center experience in intra-atrial catheters for hemodialysis

J. bras. nefrol; 39 (1), 2017
Abstract Introduction: Intra-atrial catheter (IAC) placement through an open surgical approach has emerged as a life-saving technique in hemodialysis (HD) patients with vascular access exhaustion. Objective: To assess the complications of IAC placement, as well as patient and vascular access survival a...

Morphometric study of the rostral epidural rete mirabile in the dromedary (Camelus dromedarius, Linnaeus 1758)

Int. j. morphol; 34 (4), 2016
In camels, the rostral epidural rete mirabile had a spongy appearance, and consisted of a dense network of anastomosing arteries occupying the entire cavity of the cavernous sinus. In this study, we measured the length of each rostral epidural rete mirabile lobe, taken between the rostral and the caudal ...

Evaluation of the effects of intra-arterial sugammadex and dexmedetomidine: an experimental study

Rev. bras. anestesiol; 66 (5), 2016
Abstract Background: Intra-arterial injection of medications may cause acute and severe ischemia and result in morbidity and mortality. There is no information in the literature evaluating the arterial endothelial effects of sugammadex and dexmedetomidine. The hypothesis of our study is that sugammadex ...

Importância dos cuidados de enfermagem no cateterismo cardíaco

Ciênc. cuid. saúde; 15 (3), 2016
RESUMO O cateterismo cardíaco é um método de diagnóstico invasivo, utilizado no tratamento precoce de pacientes com problemas cardíacos. Objetivou-se nesse estudo verificar as complicações ocorridas e os principais cuidados de enfermagem realizados antes, durante e após o cateterismo cardíaco, a...

Role of NO in arterial vascular function of intertidal fish (Girella laevifrons) and marine fish (Isacia conceptionis)

Braz. j. biol; 76 (2), 2016
Abstract Previous studies performed in intertidal fish (Girella laevifrons),as well as marine fish (Isacia conceptionis), showed that acetylcholine (ACh) produced contractions mediated by cyclooxygenases that were dependent on the area and potency of contraction in several arterial vessels. Given that th...
