STUDY of the syndromes associated with pituitary adenoma began with the description of acromegaly by Marie (1886), and many reports of the symptomatology of the tumour have since appeared (Cushing, 1912; Cairns, 1935; Henderson, 1939; Jefferson, 1940; Bakay, 1950; Younghusband, Horrax, Hurxthal, Hare, and Poppen, 1952; Nurnberger and Korey, 1953; Mogensen, 1957; Ray and Patterson, 1962; Poppen,...

BACKGROUND The elderly undergo cardiac surgery more and more frequently, often present multiple comorbidities, assume chronic therapies, and present a unique physiology. Aim of our study was to analyze the experience of a referral cardiac surgery center with all types of cardiac surgery interventions performed in patients ≥80 years old over a six years' period. METHODS A retrospective observa...

BACKGROUND SEN virus is a blood-borne, single-stranded, nonenveloped DNA virus. Two of its strains (D and H), appear to be associated with non-A-to-E hepatitis more frequently than the others, although it is not clear whether this observation has any significance. The prevalence of SEN virus in otherwise healthy individuals, including blood donors, differs markedly by geographic region. In this...

Rossi X-ray Timing Explorer (RXTE) All Sky Monitor observations of the transient Be star X-ray source X0726−260 suggest a 34.5 day period. This is apparently confirmed by a serendipitous RXTE Proportional Counter Array (PCA) slew detection of the source on 1997 May 5, near the time of a predicted flux maximum. A subsequent 5ks pointed observation of X0726−260 with the RXTE PCA detector was carr...

This study evaluated the effects of calf management system following early-weaning (EW) on performance of beef steers. On d 0, Brahman x British steers (n = 40; bodyweight [BW] = 198 ± 26 lb; age = 72 ± 14 d) were stratified by age and BW, and randomly assigned to normal-weaning (NW; d 177) or 1 of 3 EW treatments: 1) EW and grazed on ryegrass pastures for 67 d then on bahiagrass pastures until...

The effect of decompression on the structure of Methanococcus jannaschii, an extremely thermophilic deep-sea methanogen, was studied in a novel high-pressure, high-temperature bioreactor. The cell envelope of M. jannaschii appeared to rupture upon rapid decompression (ca. 1 s) from 260 atm of hyperbaric pressure. When decompression from 260 atm was performed over 5 min, the proportion of ruptur...

OBJECTIVES To develop strategies to recruit and retain inactive older adults into a physical activity program. METHODS Names of 7378 older adults were obtained from 60 neighborhoods. Then, 6401 potential subjects were matched to telephone numbers and phoned. Subjects meeting the screening criteria were invited to join the program (n = 4209). Walk leaders and social support were used to enhanc...
