The Crises of Marxism in Post-Positivist Perspective

Autor: J. W. Haycock

Publikováno v: Review of Radical Political Economics. 24:166-185

Drawing on post-positivist discourse within the philosophy of science, this paper argues that the phenomenon known as the "crisis of Marxism" is really two distinct phenomena. One is a crisis internal to the irregular series of theories identified wi

Site-directed mutagenesis of serine 40 of rat tyrosine hydroxylase. Effects of dopamine and cAMP-dependent phosphorylation on enzyme activity

Autor: J W Haycock, S. C. Daubner, C Lauriano, Paul F. Fitzpatrick

Publikováno v: Journal of Biological Chemistry. 267:12639-12646

Rat tyrosine hydroxylase expressed with a baculovirus expression system contains covalent phosphate and has kinetic parameters consistent with those expected of phosphorylated enzyme (Fitzpatrick, P. F., Chlumsky, L. J., Daubner, S. C., and O'Malley,

Depolarization-stimulated catecholamine biosynthesis: involvement of protein kinases and tyrosine hydroxylase phosphorylation sites in situ

Autor: M F, Salvatore, J C, Waymire, J W, Haycock

Publikováno v: Journal of neurochemistry. 79(2)

Depolarizing stimuli increase catecholamine (CA) biosynthesis, tyrosine hydroxylase (TH) activity, and TH phosphorylation at Ser19, Ser31, and Ser40 in a Ca(2+)-dependent manner. However, the identities of the protein kinases that phosphorylate TH un

Cellular and hormonal regulation of pigmentation in human ocular melanocytes

Autor: L C, Smith-Thomas, M, Moustafa, R A, Dawson, M, Wagner, C, Balafa, J W, Haycock, A H, Krauss, D F, Woodward, S, MacNeil

Publikováno v: Pigment cell research. 14(4)

The purpose of this study was to examine some of the factors that may be relevant to regulating pigmentation in the human eye, specifically whether choroidal and iridial melanocytes are sensitive to regulation by epithelial and stromal cells and alph

Differential regulation of tyrosine hydroxylase in the basal ganglia of mice lacking the dopamine transporter

Autor: M, Jaber, B, Dumartin, C, Sagné, J W, Haycock, C, Roubert, B, Giros, B, Bloch, M G, Caron

Publikováno v: The European journal of neuroscience. 11(10)

Mice lacking the dopamine transporter (DAT) display biochemical and behavioural dopaminergic hyperactivity despite dramatic alteration in dopamine homeostasis. In order to determine the anatomical and functional integrity of the dopaminergic system,

Immunohistochemical studies on phosphorylation of tyrosine hydroxylase in central catecholamine neurons using site- and phosphorylation state-specific antibodies

Autor: Z Q, Xu, J Y, Lew, K, Harada, K, Aman, M, Goldstein, A, Deutch, J W, Haycock, T, Hökfelt

Publikováno v: Neuroscience. 82(3)

Antibodies raised to phosphorylated forms of tyrosine hydroxylase, the first and rate-limiting enzyme in the catecholamine biosynthesis, were applied in immunohistochemical studies on rat brain slices incubated in vitro with a phosphodiesterase inhib

Fluorescent light activates the immunomodulator cis-urocanic acid in vitro: implications for patients with systemic lupus erythematosus

Autor: H McGrath, J W Haycock, J M Bell

Publikováno v: Annals of the rheumatic diseases. 53(6)

OBJECTIVE--Erythemagenic (295-305 nm) ultraviolet-B (UVB) radiation is toxic to patients with systemic lupus erythematosus (SLE). Cool white fluorescent lamp emissions produce a similar toxicity even though the UVB radiation emitted is primarily at t

Vasoactive intestinal polypeptide induces tyrosine hydroxylase in PC12 cells

Autor: M, Wessels-Reiker, J W, Haycock, A C, Howlett, R, Strong

Publikováno v: The Journal of biological chemistry. 266(15)

Physiological stress induces tyrosine hydroxylase, the rate-limiting enzyme for catecholamine biosynthesis, via trans-synaptic mechanisms within the adrenal medulla. Previous studies have implicated cAMP as a second messenger capable of inducing tyro
