    Abstract : Knowledge of the relationship between in vivo contrast agent concentration and magnetic resonance (MR) signal response is an important requirement in contrast enhanced MR imaging in general and in MR based perfusion imaging in particular. This relationship is a complex function of the properties of the contrast agent as well as the structure of the target tissue. READ MORE

    Abstract : Hyaluronan (HA) is a natural polysaccharide in the glycosaminoglycan (GAG) family with repeating units of N-acetylglucosamine (GlcNAc) and glucuronic acid (GlcA), which are linked by β(1→4) and β(1→3) glycosidic linkages. HA has many important regulatory functions in the human body, but comprehension of its structure-function relationship remains limited. READ MORE
