Phytochemical Characterization, Antioxidant Activity, and Cytotoxicity of Methanolic Leaf Extract of (Green Type) (Thunb.) Jacq.

genus has been extensively studied due to its diverse biological activities. We evaluated the methanolic extract of leaves of (Green type) (Thunb.) Jacques, the species that is less studied compared to .

The first water-soluble polynuclear metallamacrocyclic Sr(ii)-Cu(ii) complex based on simple glycinehydroximate ligands.

Recently, aminohydroximate ligands have found wide applications in the fascinating class of polynuclear metallamacrocyclic compounds named 15-MC-5 metallacrowns. The enhanced interest in water-soluble aminohydroximate Ln(iii)-Cu(ii) complexes is largely due to their rich coordination chemistry, diverse properties and ease of synthesis. We examined glycinehydroxamic acid as a simple ligand for the preparation of the first water-soluble polynuclear metallamacrocyclic Sr(ii)-Cu(ii) compound.

Effect of peripheral opioid receptor agonists on depressive activity of ethanol.

We studied the effect of peripheral μ- and κ-opioid receptor agonists (not crossing the bloodbrain barrier) on locomotor activity and metabolism in rats after acute administration of ethanol. Intraperitoneal injection of ethanol in a single dose of 2 g/kg had a strong depressive effect manifested in a decrease in horizontal locomotor activity and suppression of metabolism. μ-Opioid receptor agonist DAMGO and κ-opioid receptor agonist ICI 204,448 partly abolished the effect of ethanol on locomotor activity of rats.

Laser monitor for non-destructive testing of materials and processes shielded by intensive background lighting.

A single-pulse imaging laser projection system (laser monitor) is proposed for real-time monitoring high-speed processes shielded by the intensive background lighting. The brightness temperature of the lighting can reach thousands or even tens of thousands of degrees, which makes it difficult to observe the processes with the naked eye. The estimates of limiting temperatures show that the use of the proposed instrument allows to view the objects when the equivalent brightness temperature of the background lighting is up to 45,000 K.

Peripheral administration of loperamide and methylnaloxone decreases the degree of anxiety in rats.

We studied the effect of μ-opioid receptor ligands on anxious and depressive behavior of rats. Intragastric administration of loperamide and methylnaloxone reduced animal anxiety evaluated by an increase in the number of entries into and time spent in open arms of the elevated plus-maze. μ-Opioid receptor agonist loperamide had the most pronounced anxiolytic effect.
