Rose Bengal Photothrombosis by Confocal Optical Imaging In Vivo: A Model of Single Vessel Stroke Lora Talley Watts1, Wei Zheng1, R. Justin Garling2, Victoria C. Frohlich3, James Donald Lechleiter1 1Department of Cellular and Structural Biology, The University of Texas Health Science Center San Antonio, 2School of Medicine, The University of Texas Health Science Center San Antonio, 3Cell & Tissue Imaging Center, St. Jude Childrens Research Hospital Here, we describe a semi-invasive optical microscopy approach for the induction of a Rose Bengal photothrombotic clot in the somatosensory cortex of a mouse in vivo. The technical aspects of the imaging procedure are described from induction of a photothrombotic event to application and data collection.
Visualizing Angiogenesis by Multiphoton Microscopy In Vivo in Genetically Modified 3D-PLGA/nHAp Scaffold for Calvarial Critical Bone Defect Repair Jian Li1, Holger Jahr2,3, Wei Zheng4, Pei-Gen Ren1 1Center for Translational Medicine Research and Development, Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences, 2Department of Orthopedic Surgery, Maastricht UMC+, 3Department of Orthopaedic Surgery, University Hospital RWTH, 4Research Laboratory for Biomedical Optics and Molecular Imaging, Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences Here, we present a protocol to visualize blood vessel formation in vivo and in real-time in 3D scaffolds by multiphoton microscopy. Angiogenesis in genetically modified scaffolds was studied in a murine calvarial critical bone defect model. More new blood vessels were detected in the treatment group than in controls.

Two Novel Ansamitocin Analogs from Actinosynnema Pretiosum Natural Product Research. 2013 | Pubmed ID: 23061718 By using various column chromatography for purification, two new compounds of ansamitocin (1 and 2) were isolated from the extracts of fermentation broth of Actinosynnema pretiosum FIM06-0063. Their structures were established as maytansinol-9-methyl ether-3-propionate (1) and maytansinol-9-methyl ether-3-3'-methy-butyrate (2), respectively, by an extensive NMR analysis.
