Idiopathic pulmonary fibrosis (IPF), the most common and lethal of the idiopathic interstitial pneumonias, is defined by a radiological and/or pathological pattern of usual interstitial pneumonia (UIP). However, UIP is not synonymous with IPF as other clinical conditions may be associated with UIP, including chronic hypersensitivity pneumonitis, collagen vascular disease, drug toxicity, asbesto...

Idiopathic pulmonary fibrosis (IPF), a progressive and fatal diffuse parenchymal lung disease, is defined pathologically by the pattern of usual interstitial pneumonia (UIP). Unfortunately, a surgical lung biopsy cannot be performed in all patients due to comorbidities that may significantly increase the morbidity and mortality of the procedure. High-resolution computed tomography (HRCT) has be...

Fibrotic pulmonary and pleural disorders represent a group of intrathoracic disorders with different etiologies and prognoses. A prominent part of both pulmonary and pleural fibrotic disorders remains etiologically unknown. An essential feature for all these disorders is an increase and disarray of many extracellular matrix proteins which take part in the remodeling of the fibrotic tissue. Furt...

BACKGROUND/AIMS The pathogenesis of idiopathic pulmonary fibrosis (IPF)/usual interstitial pneumonia (UIP), a chronic and incurable human respiratory disease, is not well established. This study was designed to investigate whether the apoptosis of type II pneumocytes could be the precipitating factor in the pathogenesis of IPF. METHODS Nineteen specimens obtained by retrospective review of th...

Among the idiopathic interstitial pneumonias, the two entities-idiopathic pulmonary fibrosis (IPF) characterised by the presence of the usual interstitial pneumonia pattern of histopathology (IPF/UIP) and non-specific interstitial pneumonia (NSIP; same nomenclature for the histopathological pattern and idiopathic disease) - have provoked considerable debate. IPF/UIP and NSIP closely mimic each ...

The UIP theorem has had very little empirical support over the past 25 years. Moreover, it has been shown that high-rate currencies have tended to appreciate and low-rate currencies to depreciate, the reverse of theory. The failure of UIP has been no secret to participants in currency markets, where the carry trade, which is essentially a bet against UIP, has become a very popular investment st...

OBJECTIVES We propose a novel computational approach for the automated classification of classic versus atypical usual interstitial pneumonia (UIP). MATERIALS AND METHODS Thirty-three patients with UIP were enrolled in this study. They were classified as classic versus atypical UIP by a consensus of 2 thoracic radiologists with more than 15 years of experience using the American Thoracic Soci...

BACKGROUND Anti-endothelial cell antibodies (AECA) are circulating antibodies that bind to endothelial antigens and induce endothelial cell damage. AECA have been detected in patients with collagen vascular disease (CVD) and their presence is associated with interstitial lung disease (ILD) in cases of CVD. However, the prevalence of AECA in patients with idiopathic interstitial pneumonias (IIPs...

OBJECTIVE We wanted to determine whether the amount and shape of the anterior mediastinal fat in the patients suffering with usual interstitial pneumonia (UIP) or nonspecific interstitial pneumonia (NSIP) was different from those of the normal control group. MATERIALS AND METHODS We selected patients who suffered with UIP (n = 26) and NSIP (n = 26) who had undergone CT scans. Twenty-six contr...

Seven cannulated (rumen and duodenal) Angus x Hereford steers (264 +/- 8 kg BW) consuming low-quality forage (5% CP; 61% NDF; 31% ADF) were used to determine the influence of CP degradability and supplementation frequency (SF) on DMI and nutrient digestion. Treatments included an unsupplemented control and degradable intake protein (DIP) or undegradable intake protein (UIP) provided daily, ever...
