On the real zeroes of the Hurwitz zeta-function and Bernoulli polynomials (2002)

Veselov, A. P., Ward, J. P.

The behaviour of real zeroes of the Hurwitz zeta function $$\zeta (s,a)=\sum_{r=0}^{\infty}(a+r)^{-s}\qquad\qquad a > 0$$ is investigated. It is shown that $\zeta (s,a)$ has no real zeroes...

On the real zeroes of the Hurwitz zeta-function and Bernoulli polynomials (2002)

Veselov, A.P., Ward, J.P.

This pre-print has been submitted, and accepted, to the journal, Journal of Mathematical Analysis and Applications [© Elsevier]. The definitive version: VESELOV, A.P. and WARD, J.P., 2005. On the...

The effects of dietary potassium depletion on the ultrastructure of cardiac ventricular myocytes in rabbits: a morphometric study.

Skepper, J N, Warley, A, Ward, J P

The ultrastructure of cardiac ventricular myocytes isolated from normal and chronically K-depleted rabbits was analysed using morphometric techniques. Myocytes from normal animals showed a...

The effects of dietary potassium depletion on the ultrastructure of cardiac ventricular myocytes in rabbits: a morphometric study.

Skepper, J N, Warley, A, Ward, J P

The ultrastructure of cardiac ventricular myocytes isolated from normal and chronically K-depleted rabbits was analysed using morphometric techniques. Myocytes from normal animals showed a...

Differences in sensitivity to the specific protein kinase C inhibitor Ro31-8220 between small and large bronchioles of the rat.

Chopra, L C, Twort, C H, Ward, J P

1. The involvement of protein kinase C (PKC) in constriction of small bronchioles has never been investigated. In this study we have examined the effects of the specific PKC inhibitors Ro31-8220 and...

Direct action of BRL 38227 and glibenclamide on intracellular calcium stores in cultured airway smooth muscle of rabbit.

Chopra, L. C., Twort, C. H., Ward, J. P.

The effects of BRL 38227 and glibenclamide on intracellular calcium stores were investigated in permeabilized cultured airway smooth muscle cells of the rabbit using 45Ca effluxes. BRL 38227 (10...

Inositol 1,4,5-trisphosphate- and guanosine 5'-O-(3-thiotriphosphate)-induced Ca2+ release in cultured airway smooth muscle.

Chopra, L. C., Twort, C. H., Cameron, I. R., Ward, J. P.

1. The interaction between inositol 1,4,5-trisphosphate (InsP3) and guanosine 5'-O-(3-thio triphosphate) (GTP gamma S) releasable calcium (Ca2+) pools was examined using 45Ca effluxes in...

Potassium currents in human freshly isolated bronchial smooth muscle cells.

Snetkov, V. A., Hirst, S. J., Twort, C. H., Ward, J. P.

1. K+ currents were studied in smooth muscle cells enzymatically dissociated from human bronchi, by use of the patch-clamp technique. 2. In whole-cell recordings a depolarization-induced,...

Ligustrazine-induced endothelium-dependent relaxation in pulmonary arteries via an NO-mediated and exogenous L-arginine-dependent mechanism.

Peng, W., Hucks, D., Priest, R. M., Kan, Y. M., Ward, J. P.

1. Ligustrazine (tetramethylpyrazine, TMP) is a vasodilator that has been reported to have pulmonary selective properties in vivo, but not in vitro. Although TMP is generally described as being...

Vasopressin and oxytocin release during prolonged environmental hypoxia in the rat

Kelestimur, H., Leach, R. M., Ward, J. P., Forsling, M. L.

BACKGROUND: The mechanism causing peripheral oedema in hypoxaemic chronic obstructive pulmonary disease has not been established. Vasopressin, a powerful antidiuretic hormone involved in salt and...

Gamma-glutamyl transpeptidase. A sensitive indicator of renal ischaemic injury in experimental animals and renal homograft rejection in man.

Ward, J. P.

The sites of ischaemic injury within the kidney are reviewed and the diagnostic value of measurements of plasma and urinary enzymes in renal ischaemic injury and in renal homotransplant rejection in...
