Plasma lipid peroxidation, activity of erythrocyte superoxide dismutase (SOD) and catalase, and serum antioxidant activity (AOA) in uremic patients were examined before and after hemodialysis. An increased level of lipid peroxidation, a decreased serum AOA level, and elevated SOD and normal catalase activity before hemodialysis were observed in uremic(More)
Analyses of beat-to-beat interval variations on a continuous electrocardiogram and cardiovascular reaction during deep breathing and handgrip exercise were used as a test for autonomic nervous function in 35 obese and 18 control women. Reduced heart rate variability (HRV) in obesity indicates depression in parasympathetic activity. Indices of HRV were(More)
Combining results on quadrics in projective geometries with an algebraic interplay between finite fields and Galois rings, we construct the first known family of partial difference sets with negative Latin square type parameters in nonelementary abelian groups, the groups Z 4 × Z4`−4k 2 for all k when ` is odd and for all k < ` when ` is even. Similarly, we(More)
OBJECTIVE To determine basal levels of cytosolic calcium ([Ca2+]i) and phagocytic activity in polymorphonuclear leukocytes (PMNLs) from patients with non-insulin-dependent diabetes (NIDDM). DESIGN Prospective cohort study. SETTING A university-county hospital. MEASUREMENTS Cytosolic calcium levels, adenosine triphosphate (ATP) content, and(More)
Let (G;) be a permutation group of degree n. Let V (G;) be the set of all square matrices of order n which commute with all permutation matrices corresponding to permutations from (G;): V (G;) is a matrix algebra which is called the centralizer algebra of (G;): In this paper we introduce the combinatorial analogue of centralizer algebras, namely coherent(More)
The stabilization algorithm of Weisfeiler and Leman has as an input any square matrix A of order n and returns the minimal cellular (coherent) algebra W (A) which includes A. In case when A = A( ) is the adjacency matrix of a graph the algorithm examines all con gurations in having three vertices and, according to this information, partitions vertices and(More)
Some hormones exert their action by inducing a rise in cytosolic calcium [Ca2+]i (calcium signal), and therefore, a blunting in hormone-induced calcium signal would engender resistance to the action of the hormone. Chronic renal failure (CRF) is associated with resistance to the action of a variety of hormones, a rise in [Ca2+]i and decrease in the amount(More)
Post-heparin hepatic lipase activity is reduced in chronic renal failure (CRF). This could be due to reduced synthesis, decreased activity, and/or impaired secretion of the enzyme. Further, the factor(s) responsible for such derangements are not elucidated. We examined hepatic lipase metabolism in normal, 6-wk-old CRF rats, CRF-PTX (parathyroidectomized)(More)
Both animals and patients with chronic renal failure have impaired B cell function due, in part, to elevated levels of cytosolic calcium ([Ca2+]i). Treatment of HD patients with nifedipine has normalized [Ca2+]i of their polymorphonuclear leukocytes (PMNL) and caused marked improvement in the phagocytic property of the PMNL. This observation may have(More)
Antinociceptive activity of seven pentapeptide fragments of human adenovirus type 2 (Ad2) virion proteins: Thr-Val-Pro-Pro-Arg (1), Thr-Arg-Pro-Pro-Arg (2), Thr-Gly-Pro-Pro-Thr (3), Pro-Arg-Pro-Pro-Thr (4), Phe-Val-Pro-Pro-Arg (5), Ala-Arg-Pro-Pro-Ala (6), Tyr-Gly-Pro-Pro-Lys (7)--analogs of known tuftsin inhibitor Thr-Lys-Pro-Pro-Arg, was measured by(More)
