Tolerance to isosorbide dinitrate in isolated strips of rabbit corpus cavernosum
(BLACKWELL SCIENCE LTD, 1998)
The aim of this study was to investigate whether prolonged exposure to a high concentration of isosorbide dinitrate (ISDN) would result in tolerance being developed against its relaxant activity in strips of corpus cavernosum, ...
Optimum dragline selection for strip coal mines
(INST MINING METALLURGY, 1998)
A model is presented by means of which the optimal dragline selection may be made. An outline is given of the methodology that was adopted in developing a series of generic algorithms to first define and then formularize ...
Wavelength converter/amplifier with fine tunability
(IEEE, Piscataway, NJ, United States, 1998)
The results of the study of a novel monolithic wavelength converter/amplifier which can be tuned, with the application of an external field are presented. The tuning range is Dl=300 angstrom about the operation wavelength, ...
Impaired contraction and relaxation in the aorta of streptozotocin-diabetic rats
It is known that diabetes mellitus alters the vascular responsiveness to several vasoconstrictors and vasodilators. Endothelium-derived nitric oxide is a potent endogenous nitrovasodilator, and endothelin-1 (ET-1) is a ...
On the spectrum of the Rhaly operators on c0 and c
In this paper, we determine the spectrum of the Rhaly matrix Ra as an operator on the spaces C0 and c, when limn (n + 1)an ? 0 and exists.
On the spectrum of the Rhaly operators on c(0) and c
(INDIAN NAT SCI ACAD, 1998)
In this paper, we determine the spectrum of the Rhaly matrix R-a as an operator on the spaces c(0) and c, when lim(n) (n + l)a(n) not equal 0 and exists.
Selective shear flocculation of chromite from chromite-serpentine mixtures
(ELSEVIER SCIENCE BV, 1998)
In this study, shear flocculation of chromite from mixtures of chromite and serpentine was investigated. The effects of zeta potential, contact angle, stirrer speed, flocculation (stirring) time, settling time and concentration ...
Comparison of the Effects of Vasectomy and Experimental Cryptorchidism in Rats: I. Testicular Histology
The effects of cryptorchidism, one of the most important congenital malformations resulting with the defects in testicular structure thus infertility, is the best known subject in male reproduction. Those best known effects ...
Effect of endothelin-1 on spontaneous contractions and effects of nimodipine and isradipine on endothelin-1-induced contractions in myometrial strips isolated from normal pregnant and preeclamptic women
(MUNKSGAARD INT PUBL LTD, 1998)
Background. To examine the effect of endothelin-l (ET-1) on spontaneous contractile activity and the effects of nimodipine and isradipine on ET-l-induced contractile responses in myometrial strips isolated from normal ...
Kinematics of late pliocene-quaternary normal faulting in the southeastern end of the Gediz graben, Western Anatolia, Turkey
(V H WINSTON & SON INC, 1998)
The kinematic analysis of fault-slip data obtained from lower Pliocene and Pleistocene deposits indicates two successive extensional events in the southeastern end of the Gediz graben. The late Pliocene N-S extensional ...
