The flat oyster Ostrea edulis L. is widespread along the Italian coasts. In particular, the Manfredonia Gulf (Adriatic Sea) represents an important site where natural beds subsist. Previous monitoring conducted in 1990 by light microscopy and ultrastructural studies revealed the presence of Bonamia-like microcell parasites in some flat oysters: following(More)
A study was conducted to investigate the involvement of bacteria in oyster mortalities during summer. Moribund and apparently healthy oysters were sampled during mortality events along the French coast and in rearing facilities, usually when temperature reached 19 degrees C or higher, and oysters were in the gonadal maturation phase. Hemolymph samples were(More)
This multicentre trial compared the clinical efficacy of amoxycillin/clavulanate used as a single-agent therapy with that of the three-agent combination usually prescribed in the post-operative period for appendicular peritonitis in children. Only bacteriologically documented peritoneal infections were included. Sixty-four patients were randomly distributed(More)
OBJECTIVE The aim of this study is to compare vesical and renal calcium oxalate crystalluria in an attempt to correlate crystal formation with chemical composition and calcium oxalate saturation of renal urine. MATERIAL AND METHODS Urine specimens were directly collected from the bladder and the kidney, of 11 stone formers and 11 control subjects under(More)
Autoradiographic experiments using iodinated vasopressin analog revealed the presence of specific vasopressin-binding sites in the human adrenal cortex (zona glomerulosa and zona fasciculata). These receptors exhibited a good affinity for arginine vasopressin (3.3 nM), with classical V1a pharmacology and densities of 65 and 135 fmol/mg protein-enriched(More)
OBJECTIVE The aim of this study was to determine the usefulness of the morning calcium oxalate crystalluria in detecting stone formers particularly prone to recurrence. METHODS Over a 24-hour period of urine collection, the morning calcium oxalate crystalluria was evaluated as well as the risk of stone formation, established with Tiselius and Parks(More)
OBJECTIVE The aim of this randomized study was to assess the relation between shockwave frequency, sedation, and efficiency in piezoelectric extracorporeal shockwave lithotripsy (SWL) for ureteral calculi. METHODS A random sample of 114 patients aged between 15 and 74 (mean 45) years were treated at the shockwave frequencies of 1 (N = 57) or 4 (N = 57)(More)
OBJECTIVE To determine whether histological analysis of six multiple random biopsies of the gland or analysis of only one biopsy provides a good estimate of the different components of the hyperplastic gland compared with the results obtained from tissue specimens (reference values). MATERIALS AND METHODS The various components of prostate tissue obtained(More)
AIMS Interleukin 6 (IL-6) is expressed in the majority of renal cell carcinomas and has an important role in the proliferation of some renal cell carcinoma cell lines. This action is mediated by two membrane proteins, gp80 (the IL-6 receptor; IL-6R), which binds IL-6, and gp130, which transduces the signal. The soluble form of gp80 (sIL-6R) is able to(More)
OBJECTIVE To evaluate the circadian fluctuations in the risk of urinary calcium oxalate stone formation with regard to critical periods of crystallization. PATIENTS AND METHODS Over a given time period, the Tiselius index depends on urine volume and urinary excretion of oxalate, calcium, citrate and magnesium. This crystallization potential was evaluated(More)
