Normal human liver tissue and cultured human hepatocytes are valuable models to study xenobiotic metabolism and toxicity, but they only have a limited in vitro life-span and are not readily available. This report describes the establishment of replicative cultures of human adult liver epithelial cells in serum-free medium. The longevity of three of these(More)
PURPOSE Androgen receptor (AR) is commonly expressed in breast cancers. However, the association between tumor AR status and breast cancer survival is uncertain. Hence, we examined the association between AR status and breast cancer survival in the Nurses' Health Study (NHS). EXPERIMENTAL DESIGN It was a prospective study of postmenopausal women enrolled(More)
Prior studies have suggested a higher prevalence of high grade, ER-negative, HER2-positive, and basal-like carcinomas in young women with breast cancer. However, the precise distribution of poor prognostic features in this population remains unclear. We examined the pathologic features and distribution of molecular phenotype in relation to patient age in a(More)
Taxol is the first of a novel class of anticancer drugs, the taxanes. Taxol's unique effects include its ability to polymerize tubulin into stable microtubules in the absence of cofactors and to induce the formation of stable microtubule bundles. During its development, formidable challenges were overcome: a suitable formulation was developed, an adequate(More)
Human livers were removed at immediate autopsy (IA) from brain death patients within 1 h after cessation of cardiac function. Viable hepatocytes were isolated successfully from these IA livers by perfusion of an intack lobe with collagenase or by digestion of a small tissue wedge with collagenase-dispase. The yields of hepatocytes ranged from 1 to 3 × 106(More)
Registries, such as those for oncology, have demonstrated usefulness in collating information. Trauma care can be improved through the accumulation of local, regional, and state trauma statistics. The efforts to develop a National Trauma Registry in the United States are still in their infancy. A four-page survey questionnaire was returned by each of the 50(More)
Exploratory experiments indicate that media containing lipids, phosphoethanolamine, epidermal growth factor, insulin, cholera toxin, bovine pituitary extract, chemically denatured serum, and triiodothyronine will support replicative cultures of normal liver epithelial cells obtained from adult Rhesus monkey and human donors. In addition, we have extended(More)
Animal models of cardiac hypertrophy demonstrated increased expression of insulin-like-growth factor-1 (IGF-1) in the heart. To study protein expression of insulin-like-growth factor 1 in left ventricular hypertrophy (LVH) in humans 11 hearts of autopsy cases with LVH were compared to 11 controls using immunohistochemical staining with anti-human IGF-1. LVH(More)
We investigated the ability of atheroma-associated liposomes and malondialdehyde (MDA)-modified low-density lipoproteins (MDA-LDL) to activate complement. Complement activation markers C3a, Bb, C4d and SC5b-9 were measured in both normal and complement-deficient sera. We found that MDA-LDL was able to generate C3a and SC5b-9, predominantly by the(More)
