BACKGROUND Obstructive nephropathy is characterized at the histologic level by tubular atrophy and interstitial monocyte infiltration. The molecular mechanisms underlying these histologic changes are still poorly defined. Epidermal growth factor (EGF) produced by tubular cells seems to play a pivotal role in the modulation of tubular cell growth, while(More)
Mononuclear cell infiltration is a common histopathological feature of acute renal transplant rejection, in which it seems to play a key role in the pathogenesis of tubulointerstitial lesions. Monocyte chemotactic peptide-1 (MCP-1) is a specific chemotactic and activating factor for monocytes. Thus, the present study was aimed at evaluating MCP-1 gene and(More)
Thus far there is little data available concerning Acanthamoeba associated amoebic keratitis (AK) from Italy. In order to understand the incidence of Acanthamoeba in patients with ocular infections and to characterize the isolates at the molecular level, ocular specimens and contact lenses or lens case solutions from 140 patients were analysed by culture(More)
BACKGROUND When inhaling medication, it is essential that drug particles are delivered to all sites of lung inflammation, including the peripheral airways. The aim of this study was to assess the lung deposition and lung distribution of beclomethasone dipropionate (BDP)/formoterol (100/6 microg), both dissolved in hydrofluoroalkane (HFA) and delivered by(More)
AIM Biopsies of the gastric antrum were reviewed over a period of 10 years to determine the prevalence of Helicobacter heilmannii in symptomatic subjects from this geographical area and to relate its presence to distinctive histopathological and immunohistochemical features. METHODS Biopsies from 7926 symptomatic patients were reviewed. Ten serial(More)
The Authors have examined 10 cases of severe malnourished children (7 cases of kwashiorkor, 2 cases of marasmus, 1 case of marasmic kwashiorkor). Experiments were carried in order to detect endotoxemia by means of Limulus test, bacteremia with blood cultures and possible effects of plasma on leucocyte migration by Leucocytes Migration Agarose Test (LMAT).(More)
BACKGROUND Angiotensin II (Ang II) has been shown to be implicated in the development of renal fibrosis in several forms of chronic glomerulonephritides, but the precise mechanisms of its effects remain unclear. It has recently been reported that Ang II stimulates the expression of plasminogen activator inhibitor-1 (PAI-1) in several cell lines. PAI-1 is a(More)
Tubulointerstitial damage is a common histopathological feature of acute and chronic renal diseases and a prognostic indicator of renal function outcome. Monocytes infiltrating the interstitium, through the release of cytokines and/or growth factors, may play a key role in the pathogenesis of tubulointerstitial damage. Monocyte chemotactic peptide-1 (MCP-1)(More)
BACKGROUND Impaired changes in gastric epithelium proliferation have been described in Helicobacter pylori infection, and a progressive increase of proliferating cells has been shown with the progression of mucosal lesions. AIMS Purpose of this investigation was to study the effect of eradication on bacterium-induced proliferative changes, evaluated by(More)
BACKGROUND/PURPOSE The authors studied the potential role of ureteropelvic junction obstruction (UPJ-O) in causing progressive renal damage in children through the renal expression of epidermal growth factor (EGF) and monocyte chemotactic protein-1 (MCP-1) mRNA. METHODS Renal tissues were harvested from 11 children with UPJ-O and from 10 normal kidneys to(More)
