OBJECTIVE To assess relations between right ventricular pressure measured with a high fidelity transducer tipped catheter and the characteristics of tricuspid regurgitation recorded with Doppler echocardiography. DESIGN A prospective non-randomised study of patients with severe pulmonary hypertension referred for consideration of lung transplantation. SETTING A tertiary referral centre for ...

OBJECTIVE To characterize the 24-h habitual-position intraocular pressure (IOP) patterns of optic disc phenotypes (ODPs) in untreated normal-tension glaucoma (NTG) and the relationships between nocturnal IOP elevation and various clinical factors. DESIGN Prospective, cross-sectional, observational study. METHODS Eighty-two NTG patients with focal ischemic (FI) ODP and 82 age- and disease se...

Total scattering structure factors of per-deuterated methanol and heavy water, CD3OD D2O, have been determined across the entire composition range as a function pressure up to 1.2 GPa, by neutron diffraction. The largest variations due increasing were observed below variable value 5 Å−1, mostly shifts in terms positions first second maxima. Molecular dynamics computer simulations, using combina...

a role of adenosine in pathogenesis of syndrome x has recently been postulated. previous studies suggest that aminophylline (an adenosine receptor blocker) improves exercise tolerance in this disorder. present study was performed to examine the efficacy of theophylline in syndrome x and to determine the incidence of cardiovascular risk factors and clinical, ecg and angiographic findings in thes...
