BACKGROUND: Determinations of renal oxygenation by blood oxygenation level-dependent magnetic resonance imaging (BOLD-MRI) in chronic kidney disease (CKD) patients have given heterogeneous results, possibly due to the lack of a reproducible method to analyse BOLD-MRI. It therefore remains uncertain whether patients with CKD have a reduced renal tissue oxygenation. We developed a new method to analyse BOLD-MRI signals and applied it to CKD patients and controls. METHODS: MRI was performed under standardized conditions before and 15 min after IV furosemide in 104 CKD patients, 61 hypertensives and 42 controls...

Interstitial lung disease (ILD) is a common form of extramuscular involvement in patients with polymyositis/dermatomyositis and is associated with poor prognosis. This study was designed to describe the long-term outcome of myositis-associated ILD. This retrospective observational study was conducted in 48 consecutive patients. Two groups defined according to outcome were compared to determine prognostic factors: a "severe" group (vital capacity [VC] < 50 % or carbon monoxide transfer factor [TLCO] < 35 % or death or lung transplantation) and a "nonsevere" group (other patients)...

BACKGROUND: Declining lung function signifies disease progression in idiopathic pulmonary fibrosis (IPF). Vascular endothelial growth factor (VEGF) concentration is associated with declining lung function in 6 and 12-month studies. Alveolar nitric oxide concentration (CANO) is increased in patients with IPF, however its significance is unclear. This study investigated whether baseline plasma VEGF concentration and CANO are associated with disease progression or mortality in IPF. METHODS: 27 IPF patients were studied (maximum follow-up 65 months)...

OBJECTIVE: The determination of renal tissue oxygenation by BOLD-MRI in chronic kidney disease (CKD) patients has given heterogeneous results, possibly due to the lack of a widely accepted procedure to analyze the R2* maps. We present a new technique for the analysis of renal BOLD-MRI called the twelve-layer concentric objects method (TLCO). We measured its reproducibility and assessed whether differences in the intra-renal distribution of R2* as a measure of oxygenation were detected between CKD patients and controls...

A first-principles density functional theory (DFT) study of [Formula: see text]-(BEDT-TTF)2X molecular conductors with X  =  I3, CsCo(SCN)4 (ambient pressure, 7.5 kbar and 10 kbar), CsZn(SCN)4, TlCo(SCN)4, RbCo(SCN)4 and RbZn(SCN)4 (220 K and 90 K) is reported. It is shown that these salts exhibit three different types of band structure each of them associated with a different physical behavior. In contrast with previous proposals it is found that the key electronic parameter behind the differences in the band structures is the intrastack transfer integral, t c ...

PATIENT PRESENTATION AND DIAGNOSTIC WORK-UP: The patient is a 72-year-old man presenting with dyspnoea on exertion. He is a former heavy smoker (40 pack-years) and his father, now deceased, had rheumatoid arthritis (RA). On physical examination he had mild bi-basilar crackles but no finger clubbing. Autoimmune serology was positive for rheumatoid factor (RF: 25 IU/ml). Lung function tests showed normal FVC, a FEV1/FVC ratio of 72% and a TLCO of 49% predicted. Lung CT showed centrilobular and paraseptal emphysema, subpleural fine reticulation and traction bronchiolectasis, with no clear basal predominance (Figure 1)...

Fluoro-edenite is a natural mineral species initially isolated in Biancavilla, Sicily. The fibres are similar in size and morphology to certain amphibolic asbestos fibres, the inhalation of which may cause chronic inflammation and cancer. Occupational asbestos exposure is known to be associated with pleural and lung diseases, including pleural plaques. The aim of this study was to report the pleural and lung parenchymal lesions detected by high-resolution computed tomography (HRCT) in a group of construction workers exposed to fluoro-edenite...
