OBJECTIVE Long ureteric defects may theoretically be repaired with the use of tissue-engineered neoureter. However, attempts to construct such a neoureter in animal models have failed because of major inflammatory response. Avoidance of such inflammation requires a well-differentiated urothelium. We investigated whether omental maturation of a seeded construct in a pig model could achieve termi...

PURPOSE To evaluate macro and microscopically the late evolution of autotransplants of fragments of spleen in the greater omentum, mesenterium and peritoneal cavity, after 24 weeks of observation. METHODS Fifty two Wistar rats were used, males and adults, submitted to total splenectomy and divided in four groups. The group I--seventeen animals with implant of spleen fragment in the peritoneal...

A 42-year-old male presented to the Emergency Department complaining of right lower quadrant pain of 2 days duration. He had no previous surgical history. On physical exam, the patient was afebrile with diffuse abdominal tenderness and peritoneal irritation. White blood cell, electrolytes, amylase and lipase serum levels were normal. A contrast-enhanced CT scan of the abdomen and pelvis (Pictur...

Malignant neoplasms of the pelvic organs and abdominal cavity are often associated with peritoneal gliomatosis (PG). Detection PG its differentiation from carcinomatosis other changes in tissue using ultrasound, magnetic resonance imaging, computed tomography is extremely limited. Questions pathogenesis PG, influence on course main tumor process, as well relationship indicators overall relapse-...

idiopathic or spontaneous segmental infarction of omentum is a rare disease producing acute abdominal emergency. this rare entity is in a small group of abdominal emergencies with circulatory compromise. infarction could be caused by omental torsion which could be due to adhesion of a previouse surgery or it could be spontaneous. less than 150 cases of idiopathic segmental infarction of omentum...

Long-term dietary and pharmacological treatments for obesity have been questioned, particularly in individuals with severe obesity, so a new approach may involve adipose tissue transplants, particularly autologous transplants. Thus, the aim of this study was to evaluate the metabolic effects of autologous subcutaneous adipose tissue (SAT) transplants into two specific intraabdominal cavity site...

Nanomedicine is an emerging field with great potential in disease theranostics. We generated sterically stabilized superparamagnetic iron oxide nanoparticles (s-SPIONs) with average core diameters of 10 and 25 nm and determined the in vivo biodistribution and clearance profiles. Healthy nude mice underwent an intraperitoneal injection of these s-SPIONs at a dose of 90 mg Fe/kg body weight. Tiss...
