The method of capillary electrophoresis for quantitative determination of hydrophobized hyaluronic acid in its micellar forms.

Micelles based on hydrophobized hyaluronic acid (HA) are frequently used in targeted drug delivery systems. Capillary zone electrophoresis (CZE) was utilized for the quantitative determination of hydrophobized and native HA. A universal methodology was developed, suitable for the quantitative analysis of amphiphilic derivatives of hyaluronan (oleyl hyaluronan and hyaluronan conjugate with naphthalimide fluorophore) and native HA with varying molecular weights (15, 150, and 800 kDa).

In Vitro Effects of Fentanyl on Aortic Viscoelasticity in a Rat Model of Melatonin Deficiency.

Melatonin influences arterial biomechanics, and its absence could cause remodeling of the arterial wall, leading to increased stiffness. Direct effects of fentanyl on the aortic wall have also been observed previously. This study aimed to evaluate in vitro the effects of fentanyl on aortic viscoelasticity in a rat model of melatonin deficiency and to test the hypothesis that melatonin deficiency leads to increased arterial wall stiffness.

The spleen as a possible source of serine protease inhibitors and migrating monocytes required for liver regeneration after 70% resection in mice.

The role of the immune system in liver repair is fundamentally complex and most likely involves the spleen. The close connection between the two organs via the portal vein enables delivery of splenic cytokines and living cells to the liver. This study evaluates expression of inflammation-related genes and assesses the dynamics of monocyte-macrophage and lymphocyte populations of the spleen during the recovery from 70% hepatectomy in mice.
