The primary objective of this study was to investigate the phosphodiesterase inhibitory activity of flavonoids using in silico docking studies. In this perspective, flavonoids like Apigenin, Baicalin, Chrysin, Genistein, Scopoletin and Caffeine were selected. Caffeine, a known phosphodiesterase inhibitor was used as the standard. In silico docking studies were carried out using AutoDock 4.2, based on the Lamarckian genetic algorithm principle. In the docking studies, three important parameters like binding energy, inhibition constant and intermolecular energy were determined. The results showed that all the selected flavonoids showed binding energy ranging between -7.59 kcal/mol to -5.66 kcal/mol when compared with that of the standard (-4.77 kcal/mol). Inhibition constant (2.72 ${\mu}M$ to 71.03 ${\mu}M$) and intermolecular energy (-8.49 kcal/mol to -6.26 kcal/mol) of the flavonoids were coincide with the binding energy. All the selected flavonoids contributed phosphodiesterase inhibitory activity because of its functional groups. These molecular docking analyses could lead to the further development of potent phosphodiesterase inhibitors for the treatment of inflammatory disorders.

The primary objective of this study was to investigate the aldose reductase inhibitory activity of flavonoids using in silico docking studies. In this perspective, flavonoids like Apigenin, Baicalin, Daidzein, Epigallocatechin, Galangin, Genistein, Hesperitin, Naringenin, and Scopoletin were selected. Epalrestat, a known aldose reductase inhibitor was used as the standard. In silico docking studies were carried out using AutoDock 4.2, based on the Lamarckian genetic algorithm principle. In the docking studies, three important parameters like binding energy, inhibition constant and intermolecular energy were determined. The results showed that all the selected flavonoids showed binding energy ranging between -9.91 kcal/mol to -7.52 kcal/mol when compared with that of the standard (-8.73 kcal/mol). Intermolecular energy (-11.40 kcal/mol to -8.71 kcal/mol) and inhibition constant (54.78 nM to $3.10{\mu}M$) of the flavonoids also coincide with the binding energy. All the selected flavonoids contributed aldose reductase inhibitory activity because of its functional groups. These molecular docking analyses could lead to the further development of potent aldose reductase inhibitors for the treatment of diabetes.

Balloons are valuable tools in the armamentarium of a neurointerventionist. In this report, we describe 2 cases in which a balloon aided in the navigation of a second remodeling balloon through difficult vascular anatomy. The first case was a patient with a ruptured proximal posterior inferior cerebellar artery aneurysm and the second case was a patient with a ruptured anterior communicating artery aneurysm. In both cases, the coiling microcatheter and the remodeling balloon catheters were advanced through different vessels. The remodeling balloon reached the target location using a transcirculation approach, and the navigation of the remodeling balloon was aided by utilizing a second balloon. Challenging vascular anatomy is often encountered when performing neuroendovascular procedures. The strategy of using balloon assistance for the transcirculation access of a remodeling balloon can be used successfully in difficult situations to manage complex aneurysms.
