Remote ischemic preconditioning and tacrolimus in the fetal small bowel transplant in mice

Acta cir. bras; 31 (10), 2016
ABSTRACT PURPOSE: To evaluate the effect of remote ischemic preconditioning (IPC-R) in the fetal small bowel transplantation model. METHODS: Two groups were constituted: The Isogenic transplant (ISO, C57BL/6 mice, n=24) and the allogenic transplant (ALO, BALB/c mice, n=24). In each group, the animals w...

Ventral abdominal wall defect correction in rats with contaminated meshes

Acta cir. bras; 31 (10), 2016
ABSTRACT PURPOSE: To investigate whether there is a difference between Marlex(r) and Dynamesh PP-light Marlex(r) meshes, in the abdominal wall defect correction, on rats in contaminated surgical site. METHODS: Twenty-eight Wistar rats were divided into two groups of 14, and four subgroups of seven anim...

Nutritional supplementation with arginine protects radiation-induced effects. An experimental study

Acta cir. bras; 31 (10), 2016
ABSTRACT PURPOSE: To investigate the protective effect of L-arginine on the prostate (nonneoplasic) of rats with radiation-induced injury. METHODS: Twenty-nine Wistar rats, male adult, allocated into three groups: Control group (C) was not exposed to irradiation (n=10); Radiated group (R) had undergone...

Is the combination of fat grafts and platelet rich plasma effective in rats?

Acta cir. bras; 31 (10), 2016
ABSTRACT PURPOSE: To investigate if the association of fat grafts and platelet-rich plasma (PRP) improves graft viability in female rats. METHODS: This is an experimental, randomized and blinded study, which involved 47 rats. Fat was harvested from the inguinal region and grafted to the cranial region....

Arq. bras. oftalmol; 79 (5), 2016
ABSTRACT Purpose: To compare central corneal thickness (CCT) measurements of healthy individuals obtained with ultrasonic pachymetry (UP) and non-contact specular microscopy (NCSM). Method: In total, 148 eyes of 74 subjects with no ocular or systemic diseases were included in the study. Central corneal...

Experience with a third-generation parathyroid hormone assay (BIO-PTH) in the diagnosis of primary hyperparathyroidism in a Brazilian population

ABSTRACT Objective To evaluate the usefulness of a third-generation PTH assay in the diagnosis of primary hyperparathyroidism (PHPT). Subjects and methods Forty-one PHPT patients (4 men and 37 women) with 61.2 ± 10.9 (mean ± SD) years, were studied and had PTH levels measured with two different met...

Accuracy of the Electrocardiogram in Localizing the Accessory Pathway in Patients with Wolff-Parkinson-White Pattern

Arq. bras. cardiol; 107 (4), 2016
Abstract Background: There are currently several electrocardiographic algorithms to locate the accessory pathway (AP) in patients with Wolff-Parkinson-White (WPW) syndrome. Objective: To compare the ability of electrocardiographic algorithms in identifying the location of the AP in patients with WPW pa...

Fragmented QRS for Risk Stratification in Patients Undergoing First Diagnostic Coronary Angiography

Arq. bras. cardiol; 107 (4), 2016
Abstract Background: Only a small proportion of patients referred for coronary angiography with suspected coronary artery disease (CAD) have the diagnosis of obstructive CAD confirmed by the exam. For this reason, further strategies for risk stratification are necessary. Objective: To investigate the r...

Effects of Nitrate Intake on Myocardial Ischemia-Reperfusion Injury in Diabetic Rats

Arq. bras. cardiol; 107 (4), 2016
Abstract Background: Coronary artery disease is 2-3 times more common in diabetic individuals. Dietary nitrate/nitrite has beneficial effects in both diabetes and cardiovascular disease. It also has protective effects against myocardial ischemia-reperfusion (IR) injury in healthy animals. However, the e...
