Macrophage migration inhibitory factor in lung tissue of idiopathic pulmonary fibrosis patients.

Introduction: Idiopathic pulmonary fibrosis (IPF) is a severe interstitial lung disorder characterized by a pattern of Usual Interstitial Pneumonia where the presence of fibroblastic foci is the hallmark of the disease.

Aim Of The Study: In the present study, we analyzed the migration inhibitory factor (MIF) expression in lung tissue of IPF patients compared with healthy controls and organizing pneumonia (OP) patients focusing into MIF potential role in fibroblastic foci development.

Materials And Methods: The immunohistochemical analysis was performed in 10 IPF patients (7 male), 3 OP patients (2 male), and 3 healthy controls (all male) using the streptavidin-biotin method (Dako).

Low concentrations of Bisphenol A and para-Nonylphenol affect extravillous pathway of human trophoblast cells.

Bisphenol A (BPA) and para-Nonylphenol (p-NP) are chemicals of industrial origin which may influence human reproductive health. The effects of these substances in the prenatal life is an important topic that is receiving greater attention in the developed countries. In this study, human trophoblast cells HTR-8/SVneo were exposed to BPA and p-NP (1 × 10(-15), 1 × 10(-13), 1 × 10(-11), 1 × 10(-9) and 1 × 10(-7) M) and incubated for 24, 48 and/or 72 h then, examined for the main physiological processes which characterize the extravillous trophoblast.

Cystic gastrointestinal stromal tumors of the pancreas simulating cystoadenocarcinoma. Report of three cases and short review of the literature.

Gastrointestinal stromal tumors (GISTs) represent a distinct subset of mesenchymal tumours of the gastrointestinal tract. They are more common in the stomach and small intestine, and are characterized by the proliferation of spindle or epithelioid cells and by the expression of CD117. Extra-gastrointestinal stromal tumors are rare and only 13 cases of pancreatic GISTs have been reported in the literature, only 1 of which presented as a cystic lesion.

Translationally controlled tumour protein (TCTP) is present in human cornea and increases in herpetic keratitis.

Background: Translationally controlled tumour protein is a multifunctional calcium binding protein which has an important role in apoptosis, calcium levels balance and immunological response. The aim of this study was to evaluated the presence and distribution of TCTP in healthy human corneas and to identify and characterize the presence and distribution of this protein in human normal cornea. Since recent studies suggest that apoptosis, calcium levels and immunological mechanisms play a role in the pathogenesis of herpetic stromal keratitis, we studied TCTP expression in this disease.

Fulminant intravascular lymphomatosis mimicking acute haemorrhagic leukoencephalopathy.

Background: Intravascular lymphomatosis (IVL) is a rare non-Hodgkin's lymphoma, usually of B cell lineage, characterized by massive angiotropic growth. The clinical presentation of IVL may include changes in mental status, non-localizing neurological deficits, seizures, fever of unknown origin and skin changes. Because of its rarity and the absence of specific diagnostic procedures except for cerebral biopsy, diagnosis is often postmortem.
