The size distribution of new vesicles formed after addition of oleate in different forms to preformed egg yolk phosphatidylcholine (EggPC) vesicles was studied by gel exclusion chromatography. The addition of oleate to preformed vesicles resulted in the formation of new small vesicles. Fission of preformed vesicles incorporated by oleate and partial solubilization of the vesicles by addition of...

The performance of parallelized connected component labeling can be improved in two ways: faster local labeling and faster interprocessor communication. Suzuki et al. describe one method of improving the speed of the local labeling procedure through the use of another table that remembered component labels. In speeding up global information dissemination, one may either allow each component to ...

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...

The capacity of specifically targeted erythrocytes to inhibit free radical-mediated injury to the endothelial cell after cold preservation, and improve liver function was studied in two experimental models: An isolated perfused rat liver (IPRL) system and syngeneic orthotopic rat liver transplantation. In the IPRL model, livers were preserved in University of Wisconsin solution for 24 h at 4 de...

We examined whether angiotensin (Ang) II receptor antagonists could be considered a therapeutic strategy in steatotic and nonsteatotic livers in conditions of partial hepatectomy under ischemia-reperfusion (I/R), which is commonly applied in clinical practice to reduce blood loss. We report that Ang II type I receptor (AT1R) antagonist, but not Ang II type II receptor (AT2R) antagonist, increas...

AIM To investigate gender-specific liver estrogen receptor (ER) expression in normal subjects and patients with hepatitis C virus (HCV)-related cirrhosis and hepatocellular carcinoma (HCC). METHODS Liver tissues from normal donors and patients diagnosed with HCV-related cirrhosis and HCV-related HCC were obtained from the NIH Liver Tissue and Cell Distribution System. The expression of ER sub...

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...
