The indicator dilution technique has evolved into an invaluable method for the detection and localization of congenital and acquired cardiac shunts. The groundwork for much of the work in this field has been laid by Wood, Swan, and Helmholz (1957); Swan (1959); Hetzel, Swan, and Wood (1959); Braunwald, Tanenbaum, and Morrow (1958) and Braunwald and Morrow (1960). Indocyanine green is the most c...

osteoporosis (op) is a frequent complication of rheumatoid arthritis (ra) and longitudinal studies have documented increased rate of bone loss in ra patients. to determine the frequency of low bone mass as well as the influence of disease duration and corticosteroid use on bone mass in patients with ra, 88 patients with ra and 112 age matched controls were studied. bone densitometry was perform...

Abstract datatypes can be typed conveniently using existential types. Even though it is a powerful abstraction mechanism, current type inference systems based on Hindley-Milner do not allow existential types as first-class citizens – every existential type must be explicitly declared, packed, and unpacked using a data constructor. We present an extension of theMLF type system with first-class e...

The association of muscle hypertophy in the outflow tract of a ventricle with obstruction to blood flow during systole is being recognized with increasing frequency. This functional stenosis has long been known to appear in the hypertrophied right ventricle following surgical relief of pulmonary valve stenosis (Kirklin et al., 1953; Brock, 1955). It was recognized in the left ventricle by Brock...
