The Significance of Anatomical Variations of Hepatic Artery and Multiple Arterial Supplies in Embolization of Liver Tumors

A new therapeutic measure-step by step-embolization of every feeding vessel in dealing with liver cancer has been proposed on the base of the following criteria after reviewing the coeliac and superior mesenteric arteriographies in 100 cases of liver cancer.The emphasis is put on: 1.Anatomic variation of hepatic arteries. 2. Multiple feeding vessels, and 3. The importance of the presence of stenosis after embolization and the formation of collateral circulation.

Factors affecting hydraulic conductivity and methods to measure in plants

The plant hydraulic network faces several challenges under drought stress. Hydraulic conductivity is one of the major indicators of the hydraulic network’s response to drought stress. Here, we review our current understanding of the factors directly affecting hydraulic conductivity and the methods used to measure it.
