Characterization of melatonin receptors and signal transduction system in rat arteries forming the circle of Willis

, 1994
The aims of this study were to characterize the melatonin receptors in rat brain arteries forming the circle of Willis. Saturation studies performed using in vitro autoradiography and [I-125]iodomelatonin revealed the presence of two binding sites: one ...

In Search of Enzymes with a Role in 3′, 5′-Cyclic Guanosine Monophosphate Metabolism in Plants

, 2016
In plants, nitric oxide (NO)-mediated 3′, 5′-cyclic guanosine monophosphate (cGMP) synthesis plays an important role during pathogenic stress response, stomata closure upon osmotic stress, the development of adventitious roots and transcript ...

Inhibition of the voltage-dependent calcium current by extracellular ATP in hamster ventricular cardiomyocytes

, 1997
The modulation of the high-voltage-activated calcium current (ICa) by external ATP was examined in single ventricular cardiomyocytes of the hamster using the whole-cell configuration of the patch-clamp technique.

Conformational studies of the smallest structural motifs of DNA detectable via vibrational circular dichroism: cytidylyl-(3'-5')-guanosine and guanylyl-(3'-5')-cytidine

, 1995
The infrared absorption and vibrational circular dichroism (VCD) spectra of buffered aqueous solutions of cytidylyl-(3'-5')-guanosine (5'(CG)3') and guanylyl-(3'-5')-cytidine (5'(GC)3') are reported.
