Long-term peritoneal dialysis is limited by physiologic changes in the peritoneum that lead to ultrafiltration failure. To determine the role of profibrotic cytokines in the alteration of peritoneal transport, a rodent model of transforming growth factor-beta (TGF-beta)-mediated peritoneal fibrosis was established. An adenoviral vector driving the active(More)
The equilibrium binding characteristics of a panel of six monoclonal antibodies (MAb) recognizing melanoma cell surface antigens (125 kdal cell surface melanoma associated glycoprotein antigen, 125kD-MAA; high molecular weight melanoma associated antigen, HMW-MAA; and a non-protein melanoma associated antigen, NP-MAA) were investigated using the cell lines(More)
The time-dependent (5 min-72 h) localization of 3 radiolabeled anti-melanoma monoclonal antibodies (MAbs 436, IND1, and 9.2.27) was studied in paired label experiments in small (4-12 mg) s.c. human melanoma xenografts (SK-MEL-2 and M21) in athymic nude mice. MAb 436 recognizes a Mr 125,000 cell surface melanoma-associated glycoprotein antigen (125 kDa-MAA);(More)
The uptake and binding of monoclonal antibodies (MAbs) in solid tumors after a bolus i.v. injection are described using a compartmental pharmacokinetic model. The model assumes that MAb permeates into tumor unidirectionally from plasma across capillaries and clears from tumor by interstitial fluid flow and that interstitial antibody-antigen interactions are(More)
High-performance anion-exchange chromatography with pulsed amperometric detection (HPAE-PAD) was evaluated for the quantitation of polyglucose metabolites (DP2-DP7) in human plasma. The method was investigated for accuracy, precision, specificity, linearity, range and analyte stability. Samples were prepared by dilution into the standard range (0.1-10(More)
The time-dependent (1-72-h) spatial distribution of three biotinylated anti-melanoma monoclonal antibodies (MAbs), a control MAb, and several macromolecular tracers was studied in two small (4-12-mg), well-characterized human melanoma xenografts (SK-MEL-2, M21) growing in the s.c. space of athymic nude mice. The specific MAbs (436, IND1, and 9.2.27)(More)
Icodextrin-based solutions have been investigated for over ten years and are commercially available in some countries in Europe. Although many studies have been described using icodextrin, we believe that there are many interesting areas remaining for clinical research with icodextrin-based PD solutions. Included in these are the careful examination of the(More)
Gene therapy is a promising new treatment modality based on molecular genetic modification to achieve a therapeutic benefit. We believe that gene therapy in the peritoneal cavity holds considerable promise, and we describe strategies by which genetic modification can be used to treat a variety of disease states or conditions. First, we can envision a(More)
