1. Prospective randomized trial comparing radiofrequency ablation and complete saphenous vein stripping in patients with mild to moderate chronic venous disease with a 3-year follow-up
RESUMO Objetivo: Comparar o uso da termoablação por radiofrequência da veia safena com a técnica de ligação e retirada completa da veia safena da junção safeno-femoral ao tornozelo. Métodos: Foram avaliados 49 pacientes com doença venosa crônica nas categorias 2 a 4 (Comprehensive Classification System for Chronic Venous Disorders − CEAP) para

2. Randomized trial of radiofrequency ablation versus conventional surgery for superficial venous insufficiency: if you don’t tell, they won’t know
OBJECTIVES: This study compared radiofrequency ablation versus conventional surgery in patients who had not undergone previous treatment for bilateral great saphenous vein insufficiency, with each patient serving as his own control. METHOD: This was a randomized controlled trial that included 18 patients and was carried out between November 2013 and May 20

3. Lesões de isquemia arteriovenosa e reperfusão em jejuno de equinos: imunoistoquímica de proteínas de junção e histopatologia
To evaluate whether complete arteriovenous ischemia followed by reperfusion of mesenteric blood flow aggravates lesions involving small intestine of horses, β--catenin and occludin expressions were measured in jejune epithelia of seven equines, without definite breed. The animals had been submitted to aseptic ventral midline celiotomy and five jejune se

5. Bilateral occlusion of basilar artery branches.
In a case in which the patient became totally paralysed except for blinking and vertical eye movements, microscopic serial sections of the pons showed bilateral infarcts which were due to occlusion of two small basilar branch arteries, one on each side. One basilar branch was occluded by an atheroma lying at its junction with the basilar artery and the other

6. Remodeling of ventricular conduction pathways in healed canine infarct border zones.
Remodeling of myocyte interconnections may be an important determinant of ventricular tachycardia in regions bordering healed infarcts. We used quantitative electron microscopy to characterize the distribution of gap junctions in 10 canine left ventricles 3-10 wk after coronary occlusion. In three normal canine left ventricles analyzed ultrastructurally, myo

7. Characterisation of the catalytically active form of RecG helicase
Replication of DNA is fraught with difficulty and chromosomes contain many lesions which may block movement of the replicative machinery. However, several mechanisms to overcome such problems are beginning to emerge from studies with Escherichia coli. An important enzyme in one or more of these mechanisms is the RecG helicase, which may target stalled replic

8. Molecular basis of calcium regulation in connexin-32 hemichannels
In addition to forming gap-junction channels, a subset of connexins (Cxs) also form functional hemichannels. Most hemichannels are activated by depolarization, and opening depends critically on the external Ca2+ concentration. Here we describe the mechanisms of action and the structural determinants underlying the Ca2+ regulation of Cx32 hemichannels. At mil

9. Escherichia coli Cytotoxic Necrotizing Factor 1 Effaces Microvilli and Decreases Transmigration of Polymorphonuclear Leukocytes in Intestinal T84 Epithelial Cell Monolayers
Cytotoxic necrotizing factor type 1 (CNF1), a 110-kDa toxin-like protein from pathogenic Escherichia coli strains, induces an actin cytoskeleton reorganization consisting of the formation of prominent stress fibers by permanent activation of the small GTP-binding protein Rho. Since p21Rho regulates tight-junction permeability and perijunctional actin reorgan

10. Effect of albumin on the osmotic pressure exerted by myoglobin across capillary walls in frog mesentery.
1. Individual capillaries in mesenteries of pithed frogs were perfused sequentially with two frog Ringer solutions containing myoglobin at a concentration of 70 mg/ml. The first perfusate solution contained bovine serum albumin at a concentration of 10 mg/ml. The second perfusate contained no albumin. The modified Landis micro-occlusion technique (Michel, Ma
