Pulmonary hypertension (PHT) is an important complication of systemic sclerosis (SSc). Echocardiography can be used to detect PHT and, with Doppler echocardiography, the pulmonary arterial systolic pressure (PASP) can often be estimated. We have undertaken a study to compare echocardiographic assessment with right heart catheterization (RHC) in 33 SSc(More)
Our objective was to evaluate the associated CT features and physiological consequences of traction bronchiectasis in patients with cryptogenic fibrosing alveolitis (CFA). The CT scans of 212 patients with CFA (158 men, 54 women; mean age 62.2±10.6 years) were evaluated independently by two observers. The extent of fibrosis, the proportions of a reticular(More)
AIMS Although pulmonary involvement is a known cause of morbidity in Niemann-Pick disease, histological features in the lung are not well characterized. The purpose of this study is to document the histological features seen in pulmonary involvement by types B and C Niemann-Pick disease and to correlate them with clinical and imaging data. METHODS AND(More)
Cerebral capillaries in “overgrown” neural tissue of chick embryo brains ranging in age from 5–18 days of incubation were studied by means of electron microscopy. The vessels in the abnormal tissue showed more extensive and prolonged interdigitations and overlapping of adjacent endothelial cells than did those in normal control brains. In the abnormal(More)
The effects of the intrarenal infusion of synthetic A sn 1, val 5 angiotensin II (AII) (from 0.38 to 1 μg min−1) on the determinants of glomerular filtration have been studied. The intracapillary and transcapillary pressure gradients along the capillaries, together with 2 parameters characterizing the porosity of the membrane in terms of pore theory (r,(More)
In this study, messenger RNA (mRNA) expression for novel T described using bioinformatics (5), including the leukotac-lymphocyte chemoattractants, leukotactin-1, macrophage inflam-tin-1 (Lkn-1)/CC chemokine ligand (CCL) 15/hemofiltrate CC matory protein (MIP)-3␣ and MIP-3␤ was investigated in bronchoal-chemokine-2 (6), macrophage inflammatory protein(More)
CCX CKR is a decoy chemokine receptor that specifically binds the chemokines CCL19, CCL25 and CCL21. CCL19 was previously found to be upregulated in pulmonary sarcoidosis. We have, therefore, investigated CCX CKR expression in this inflammatory disease. CCX CKR mRNA was semiquantitated using RT-PCR in unseparated bronchoalveolar (BAL) cells from sarcoidosis(More)
The two theoretical models proposed previously to calculate the intracapillary and transcapillary glomerular pressure gradients from the sieving of macromolecules such as PVP have been used to analyse in 22 normotensive dogs the sieving curve relating the sieving coefficients, Φ, to molecular size (Φ: glomerular clearance of PVP fractions/GFR). Neither the(More)
