Accuracy in Dental Medicine, A New Way to Measure Trueness and Precision

1Division of Computer-assisted Restorative Dentistry, Center of Dental Medicine, University of Zürich


JoVE 51374

Accuracy is a major demand in dental medicine. To verify accuracy, reference scanners are needed. This article presents a new reference scanner with an adjusted scanning method to acquire a broad variety of dental morphologies with high trueness and precision.

The 2009 Lindau Nobel Laureate Meeting: Werner Arber, Physiology or Medicine 1978


JoVE 1571

Swiss microbial geneticist, Werner Arber shared the 1978 Nobel Prize in Physiology or Medicine with Hamilton Smith and Daniel Nathans for their discovery of restriction endonucleases. Arber found that viral DNA introduced into a non-specific bacterial host was changed, while host DNA was protected by methylation. He theorized that a microbial enzyme cut the DNA into smaller pieces, while at the same time, the methylated host DNA was protected from its own enzymes. Later work done by Nathans and Smith validated his theory, which laid the foundation for recombinant DNA technology.

Modeling Astrocytoma Pathogenesis In Vitro and In Vivo Using Cortical Astrocytes or Neural Stem Cells from Conditional, Genetically Engineered Mice

1Department of Pathology and Laboratory Medicine, University of North Carolina School of Medicine, 2Lineberger Comprehensive Cancer Center, University of North Carolina School of Medicine, 3Division of Neuropathology, Department of Pathology and Laboratory Medicine, University of North Carolina School of Medicine, 4Curriculum in Genetics and Molecular Biology, University of North Carolina School of Medicine, 5Biological and Biomedical Sciences Program, University of North Carolina School of Medicine, 6Department of Radiation Oncology, Emory University School of Medicine, 7Department of Neurology, Neurosciences Center, University of North Carolina School of Medicine


JoVE 51763

Phenotypically wild-type astrocytes and neural stem cells harvested from mice engineered with floxed, conditional oncogenic alleles and transformed via viral Cre-mediated recombination can be used to model astrocytoma pathogenesis in vitro and in vivo by orthotopic injection of transformed cells into brains of syngeneic, immune-competent littermates.

Functional Magnetic Resonance Imaging (fMRI) with Auditory Stimulation in Songbirds

1Bio-Imaging Lab, University of Antwerp


JoVE 4369

This article shows an optimized procedure for imaging of the neural substrates of auditory stimulation in the songbird brain using functional Magnetic Resonance Imaging (fMRI). It describes the preparation of the sound stimuli, the positioning of the subject and the acquisition and subsequent analysis of the fMRI data.

Microwave-assisted Functionalization of Poly(ethylene glycol) and On-resin Peptides for Use in Chain Polymerizations and Hydrogel Formation

1Department of Biomedical Engineering, University of Rochester, 2Department of Chemical Engineering, University of Rochester, 3Center for Musculoskeletal Research, University of Rochester Medical Center


JoVE 50890

This video will illustrate a rapid, efficient method to methacrylate poly(ethylene glycol), enabling chain polymerizations and hydrogel synthesis. It will demonstrate how to similarly introduce methacrylamide functionalities into peptides, detail common analytical methods to assess functionalization efficiency, provide suggestions for troubleshooting and advanced modifications, and demonstrate typical hydrogel characterization techniques.

DeBakey VA Medical Center


JoVE 4235

We describe a method to genetically modify primary human T cells with a transgene using the non-viral piggyBac transposon system. T cells modified to using the piggyBac transposon system exhibit stable transgene expression.

Creating Dynamic Images of Short-lived Dopamine Fluctuations with lp-ntPET: Dopamine Movies of Cigarette Smoking

1Diagnostic Radiology, Yale University, 2Psychiatry, Yale University, 3Yale PET Center, Yale University, 4Biomedical Engineering, Yale University, 5Nuclear Medicine, Massachusetts General Hospital, 6Radiological Sciences, University of California, Irvine


JoVE 50358

We present a novel PET imaging approach for capturing dopamine fluctuations induced by cigarette smoking. Subjects smoke in the PET scanner. Dynamic PET images are modeled voxel-by-voxel in time by lp-ntPET, which includes a time-varying dopamine term. The results are 'movies' of dopamine fluctuations in the striatum during smoking.
