in this work, a new spectrophotometric method for the determination of trace amount of cobalt (іі) ionwas investigated and the stability constant of the related complex was evaluated 2.174 × 104. in the cobalt(іі)-piroxicam complex, the maximum absorbance wavelength is 570 nm and the linearity of calibrationcurve was investigated (5-10 ppm). the relative standard deviation for seven replicate e...

Two novel glucosylated zinc(ІІ) phthalocyanines 7a-7b, as well as the acetyl-protected counterparts 6a-6b, have been synthesized by the Cu(I)-catalyzed 1,3-dipolar cycloaddition between the propargylated phthalocyanine and azide-substituted glucoses. All of these phthalocyanines were characterized with various spectroscopic methods and studied for their photo-physical, photo-chemical, and photo...

Objective- The pineal gland and its principal hormone melatonin play an important role in the circadian organization in birds. However, little is known about the role of melatonin in cardiac activity of broiler chicken. The aim of this study was to assess the impact of intracerebroventricular injection of melatonin in electrocardiographic parameters, heart rate and mean electri...
