Single molecule study of cellulase hydrolysis of crystalline cellulose preprint ( Book )
1 edition published in 2009 in English and held by 151 libraries worldwide
Cellobiohydrolase-I (CBH I), a processive exoglucanase secreted by Trichoderma reesei, is one of the key enzyme components in a commercial cellulase mixture currently used for processing biomass to biofuels. CBH I contains a family 7 glycoside hydrolase catalytic module, a family 1 carbohydrate-binding module (CBM), and a highly-glycosylated linker peptide. It has been proposed that the CBH I cellulase initiates the hydrolysis from the reducing end of one cellulose chain and successively cleaves alternate ß-1,4-glycosidic bonds to release cellobiose as its principal end product. The role each module of CBH I plays in the processive hydrolysis of crystalline cellulose has yet to be convincingly elucidated. In this report, we use a single-molecule approach that combines optical (total internal reflection fluorescence microscopy or TIRF-M) and non-optical (atomic force microscopy or AFM) imaging techniques to analyze the molecular motion of CBM tagged with green fluorescence protein (GFP) and to investigate the surface structure of crystalline cellulose and changes made in the structure by CBM and CBH I. Preliminary results reveal a confined nanometer-scale movement of the TrCBM1-GFP bound to cellulose, decreases in cellulose crystal size, and increases in surface roughness during CBH I hydrolysis of crystalline cellulose.

Computed tomography : principles, design, artifacts, and recent advances by Jiang Hsieh ( Book )
4 editions published in 2009 in English and held by 99 libraries worldwide
X-ray computed tomography (CT) continues to experience rapid growth, both in basic technology and new clinical applications. Seven years after its first edition, Computed Tomography: Principles, Design, Artifacts, and Recent Advancements, Second Edition, provides an overview of the evolution of CT, the mathematical and physical aspects of the technology, and the fundamentals of image reconstruction algorithms. Image display is examined from traditional methods used through the most recent advancements. Key performance indices, theories behind the measurement methodologies, and different measurement phantoms in image quality are discussed. The CT scanner is broken down into components to provide the reader with an understanding of their function, their latest advances, and their impact on the CT system. General descriptions and different categories of artifacts, their causes, and their corrections are considered at length.
