with the writer who immediately allowed his name to be published, as may be seen by a reference to our columns (May 1911, p. 187). This letter has long been lost, but at the time we stated and we still believe that it contained nothing beyond a statement to the effect that the writer should give his name. This having been done, we did not think it necessary to publish the letter itself, and not...

The quest for a perfect heart valve substitute has been going on for half a century. In 1960, Lower et al1 described the feasibility of replacing the aortic valve of dogs with the native pulmonary valve. In 1967, Ross performed this procedure in humans.2 Ross transferred the pulmonary valve into the aortic root with the same technique used to implant aortic valve homograft3 (ie, the pulmonary s...

BACKGROUND AND OBJECTIVES Ross procedure is one of the surgical procedures for correction of severe congenital aortic insufficiency. Intraoperative transesophageal echocardiography is essential for optimal surgical evaluation. Furthermore, it is able to assess the blood volume profile and the need for administration of vasoactive drugs during surgery. CASE REPORT This is a 15-year old teenage...

OBJECTIVE Given the shortage of small-sized cryopreserved homografts for right ventricle (RV) to pulmonary artery (PA) reconstructions, more readily available larger-sized homografts can be used after size reduction by bicuspidalization. The aim of our study was to determine and compare function over time of standard and bicuspidalized homografts in infants younger than 12 months, including pat...

This paper studies comparative risk aversion between risk averse agents in the presence of a background risk. Although the literature covers this question extensively, our contribution differs from most of the literature in two respects. First, background risk does not need to be additive or multiplicative. Second, the two risks are not necessary mean independent, and may be conditional expecta...

are preserved in the Ross Archives at the London School of Hygiene and Tropical Medicine (LSHTM), and others in the Seamen's Hospital Society archive. One letter not mentioned in Cook's paper was written by Lockwood Stevens many years later, to his former secretary, Miss Ethne Roberts, who had joined him at the Ross Institute in 1926. She had transferred with him, and it, to the London School o...

A grounded ice sheet fed from the Ross Embayment filled McMurdo Sound at the last glacial maximum (LGM). This sheet deposited the little-weathered Ross Sea drift sheet, with far-traveled Transantarctic Mountains (TAM) erratics, on lower slopes of volcanic islands and peninsulas in the Sound, as well as on coastal forelands along the TAM front. The mapped upper limit of this drift, commonly mark...

Donald Nixon Ross, FRCS (4 October 1922 to 7 July 2014) was a South African-born British cardiothoracic surgeon, who developed the pulmonary autograft, known as the Ross procedure, for the treatment of aortic valve disease, and also performed the first heart transplant in the United Kingdom in 1968. This paper, written by Jane Somerville, Professor of Cardiology [Retired], Imperial College Lond...

Ocean measurements in the Ross Sea over the past four decades, one of the longest records near Antarctica, reveal marked decreases in shelf water salinity and the surface salinity within the Ross Gyre. These changes have been accompanied by atmospheric warming on Ross Island, ocean warming at depths of approximately 300 meters north of the continental shelf, a more negative Southern Oscillation...
