Damage to the fimbria-fornix, and separately to the perforant path, leads to distinct and dramatic time-dependent increases in glial fibrillary acidic protein immunoreactivity (GFAP-IR) in specific areas of the hippocampal formation. Specifically, fimbria-fornix lesions resulted in an increase in the GFAP-IR in the pyramidal and oriens area of the CA3 as(More)
BACKGROUND Interleukin-8 (IL-8) is considered a deleterious chemokine involved in renal injury in glomerulonephritis (GN). IL-8 may be released as a 77-amino acid (AA) peptide or 72-AA protein. METHODS We evaluated gene and protein expression of IL-8 in 53 renal biopsy specimens from patients with GN and 9 control kidneys. Nonradioactive in situ(More)
OBJECTIVE To compare the pre, intra, and post-operative data between ileal conduit and neobladder urinary diversions during laparoscopic radical cystectomy(LRC). MATERIAL AND METHODS Between 2006 and 2011, 63 patients who underwent LRC and urinary diversion had their data input prospectively into a database and said data used for the analysis. The outcome(More)
The influence of intensive chronic intoxication with ethanol on adult Wistar rats was investigated. The animals received through a stomach pump 5 ml of 40% ethyl alcohol solution daily for three months. Structural lesions of the CNS observed in the light microscope consisted of acute and chronic edematous changes with infiltration of mononuclear cells and(More)
OBJECTIVE We aim to evaluate our experience and results with laparoscopic radical cystectomy and conduct a systematic review of studies reporting on 50 or more procedures. MATERIALS AND METHODS Between February 2006 and March 2011, a prospective study in a single institute on patients with bladder cancer who underwent laparoscopic radical cystectomy was(More)
OBJECTIVE The aim of this study is to report our experience with laparoscopic radical cystectomy (LRC), evaluating the technique and perioperative and pathological outcomes. METHODS 47 LRCs were performed due to muscle-invasive bladder cancer. Conduits were performed in 23 patients and neobladders in 23 (one bi-intestinal). One ureterocutaneostomy was(More)
PURPOSE There is growing evidence that endothelial cells (EC) are active participants of an inflammatory process in glomeruli. MATERIAL AND METHODS We compared the glomerular expression of three EC-coupled molecules, i.e. platelet-endothelial cell adhesion molecule-1 (PECAM-1 or CD31), von Willebrand factor (vWF) and thrombomodulin (TM) in 60 patients(More)
BACKGROUND Open radical cystectomy (ORC) is the gold standard of treatment for muscle-invasive bladder cancer. Laparoscopic radical cystectomy (LRC) has emerged to provide an alternative. METHODS Between 2006 and 2012, 155 patients who underwent LRC or ORC were compared (mean follow-up 53 months). RESULTS The ORC group had shorter operative times (p <(More)
We investigated the effects of chemical convulsants in the leopard frog. Systemic kainic acid (5-20 mg/kg) caused limbic-like seizures, with staring, catatonia, fasciculations, and severe motor seizures, which were almost always lethal. Intracerebral electroencephalographic (EEG) recordings showed spike or spike-and-wave patterns at 6-8 Hz that decreased in(More)
