Probably the most common.

3-D hydrogel method of study aggressive and deadly types of brain cancer Human glioblastoma multiforme, probably the most common, aggressive and deadly forms of brain cancer, is difficult to study notoriously. Scientists have typically studied cancer cells in petri dishes, which have non-e of the properties of the mind tissues where these cancers grow, or in expensive animal models . Now a group of engineers has developed a three-dimensional hydrogel that even more closely mimics circumstances in the mind. In a paper in the journal Biomaterials, the researchers describe the new materials and their approach, that allows them to selectively tune up or down the malignancy of the cancers cells they study.

The first writer wrote the first draft of the manuscript. All the authors attest to the precision and completeness of the data and for the fidelity of the analysis to the process, which is available with the entire text of this article at Study Design The scholarly study was a phase 3, single-center, randomized, double-blind, placebo-controlled trial. We used permuted blocks of random size to stratify group assignments according to the type of process and the existence or absence of pancreatic-duct dilatation. Dilatation of the pancreatic duct was defined as a main-duct diameter of greater than 4 mm at the site of pancreatic transection on preoperative imaging.
