In the Romanian legal system, usucaption is an original way of acquiring property rights. In court actions for the establishment of the existence of the right of ownership by virtue of usucaption, the question of the passive procedural quality has frequently been raised. The general rule is that the defendant is represented by the titleholder of the property to be usucaptioned. However, in practice there are different situations which need to be adapted to each individual situation. This paper aims to present the most common situations regarding the passive legal standing in actions for the establishment of ownership by virtue of usucaption. [ABSTRACT FROM AUTHOR]

The rat is the most widely used experimental model in surgical research due to several factors, including that it is easy to handle and inexpensive. It can be used in investigations related to liver regeneration, liver metastases, or transplant immunology. This study highlights the venous components of the hepatic circulation in the Wistar rat by intravascular injection of a polymer that allows the assessment of the distribution of vessels, regardless of their caliber. Five cadavers of 11-month-old male Wistar rats from the USAMV Cluj-Napoca biobase destined for incineration, were used to highlight the liver venous system. A dye mixture, consisting of epoxy resincatalyst-blue acrylic dye in a 2:1:1 ratio, was injected. After 24 hours, biological tissues were macerated by immersion in 10% KOH solution for five days. The intrahepatic venous system is represented by the venous branches that continue into the liver lobes. Those vessels follow a parallel trajectory with the hepatic artery branches represented by the right and left ramifications. The right portal vein presents branches to the lateral and medial parts of the right lobe of the liver and the caudate lobe. The left branch of the portal vein has ramificationsfor the lateral and medial parts of the left lobe and the quadrate lobe. The technique of injecting the venous circulation of the liver, followed by tissue maceration, allowed the removal by anatomical dissection of all liver components that permits the identification of all components of the venous system, including the finest venous branches of the hepatic circulation.
