Simulated training model of ureteropyelic anastomosis in laparoscopic pyeloplasty.

Purpose: To develop a model for simulated training of ureteropyelic anastomosis in laparoscopicpyeloplasty.

Methods: Longitudinal and experimental study, with 16 participants. A synthetic instrument was produced to simulate the renal pelvis and the proximal portion of the ureter positioned on a platform within laparoscopic simulators, thereby resulting in the realistic simulation of the ureteropelvic anastomosis.

Case Report: Prolapsed Ureterocele-A Differential Diagnosis of Urethral Cists.

Ureterocele is a cystic dilatation of submucosal distal ureter. It presents a higher incidence in infants and young children but is rare in adults. The urethral prolapse of ureterocele is extremely rare, and its clinical presentation includes vulvar mass, hematuria, and urinary tract dysfunction.

Chemical Characterization and Cytoprotective Effect of the Hydroethanol Extract from Mart. (Araticum).

Introduction: Mart. (araticum) is a widely distributed tree in the cerrado. Its value is attributed principally to the consumption of its fruit which possesses a large nutritive potential.

Multiple Site Fracture of Both Rods in a Malleable Penile Implant.

Penile prosthesis implant is the definitive treatment for refractory erectile dysfunction. Fracture of malleable prosthesis is rarely described due to its low incidence. We describe a case of multiple, bilateral fracture of a malleable penile implant, ten years after implantation.

Hepatic repercussions of azoxymethane-induced colorectal carcinogenesis.

Objective: To evaluate the hepatic effects of colonic carcinogenesis induced by azoxymethane at different doses and times of exposure in rats.

Methods: Forty-four Wistar rats were divided into four groups. The animals were eight weeks at the beginning of the experiment.

Effect of a hyperlipidic diet rich in omegas 3, 6 and 9 on aberrant crypt formation in rat colonic mucosa.

Purpose: To determine whether a hypercaloric and hyperlipidic diet enriched with polyunsaturated fatty acids influences the formation of aberrant crypt foci (ACF) in colonic mucosa of Wistar rats treated with azoxymethane (AOM).

Methods: At eight weeks of life, the rats were assigned to four groups: Group I-standard diet (STD) not treated with AOM; Group II-hypercaloric and hyperlipidic diet (FED), not treated with AOM; Group III-STD, treated with AOM; Group IV-FED, treated with AOM. At 16 weeks, the animals were injected intraperitoneal with 0.

Hepatic and biochemical repercussions of a polyunsaturated fat-rich hypercaloric and hyperlipidic diet in Wistar rats.

Context: Non-alcoholic fatty liver disease is characterized by lipid deposits in the hepatocytes and has been associated with obesity, dyslipidemia and type-2 diabetes. It is considered a hepatic manifestation of the metabolic syndrome, of which the main component is insulin resistance leading to hyperinsulinemia and increased production of inflammatory cytokines. Saturated fat promotes hypertriglyceridemia and hyperinsulinemia, reduces levels of high-density cholesterol and increases levels of low-density cholesterol, while polyunsaturated fat is associated with hypolipidemic, antiinflammatory and imunoregulating action.

Experimental model of human corpus cavernosum smooth muscle relaxation.

Purpose: To describe a technique for en bloc harvesting of the corpus cavernosum, cavernous artery and urethra from transplant organ donors and contraction-relaxation experiments with corpus cavernosum smooth muscle.

Materials And Methods: The corpus cavernosum was dissected to the point of attachment with the crus penis. A 3 cm segment (corpus cavernosum and urethra) was isolated and placed in ice-cold sterile transportation buffer.

Left internal thoracic artery and saphenous vein as a composite graft: 8-year angiographic follow-up study.

The use of a composite graft with left internal thoracic artery (LITA) and arterial or saphenous vein (SV) grafts can allow the complete revascularization of the left coronary system (LCS) without cardiopulmonary bypass (CPB) and without ascending aorta manipulation (AAM), in order to reduce some complications in the immediate postoperative. This study shows 8-year angiographic follow-up results of two patients underwent no-touch aorta off-pump coronary artery bypass grafting (CABG) using LITA and SV as a composite graft to supply LCS.

Optimization of visibility and quantification of aberrant crypt foci in colonic mucosa in Wistar rats.

Purpose: Test immersion of microscopy samples in water as an aid to visualizing and quantifying aberrant crypt foci (ACF) in rat colon mucosa.

Methods: Carcinogenesis was induced with azoxymethane in Wistar rats kept on a conventional diet or a hypercaloric diet containing unsaturated fat. Fifteen weeks after induction, colon samples were retrieved and fixated in a 10% formaldehyde solution.
