Altered trabecular bone structure and delayed cartilage degeneration in the knees of collagen VI null mice.
(PLoS One, 2012)Mutation or loss of collagen VI has been linked to a variety of musculoskeletal abnormalities, particularly muscular dystrophies, tissue ossification and/or fibrosis, and hip osteoarthritis. However, the role of collagen ... -
An enteroendocrine cell-enteric glia connection revealed by 3D electron microscopy.
(PLoS One, 2014)The enteroendocrine cell is the cornerstone of gastrointestinal chemosensation. In the intestine and colon, this cell is stimulated by nutrients, tastants that elicit the perception of flavor, and bacterial by-products; ... -
Characterization of topographical effects on macrophage behavior in a foreign body response model.
(Biomaterials, 2010-05)Current strategies to limit macrophage adhesion, fusion and fibrous capsule formation in the foreign body response have focused on modulating material surface properties. We hypothesize that topography close to biological ... -
Dental microwear in live, wild-trapped Alouatta palliata from Costa Rica.
(Am J Phys Anthropol, 1991-07)One problem with dental microwear analyses of museum material is that investigators can never be sure of the diets of the animals in question. An obvious solution to this problem is to work with live animals. Recent work ... -
Functional properties of cell-seeded three-dimensionally woven poly(epsilon-caprolactone) scaffolds for cartilage tissue engineering.
(Tissue Eng Part A, 2010-04)Articular cartilage possesses complex mechanical properties that provide healthy joints the ability to bear repeated loads and maintain smooth articulating surfaces over an entire lifetime. In this study, we utilized ... -
G protein signaling and vein graft intimal hyperplasia: reduction of intimal hyperplasia in vein grafts by a Gbetagamma inhibitor suggests a major role of G protein signaling in lesion development.
(Arterioscler Thromb Vasc Biol, 1998-08)Vein grafting results in the development of intimal hyperplasia with accompanying changes in guanine nucleotide-binding (G) protein expression and function. Several serum mitogens that act through G protein-coupled receptors, ... -
Inkless microcontact printing on SAMs of Boc- and TBS-protected thiols.
(Nano Lett, 2010-01)We report a new inkless catalytic muCP technique that achieves accurate, fast, and complete pattern reproduction on SAMs of Boc- and TBS-protected thiols immobilized on gold using a polyurethane-acrylate stamp functionalized ... -
Morphological and genomic characterization of Filobasidiella depauperata: a homothallic sibling species of the pathogenic cryptococcus species complex.
(PLoS One, 2010-03-10)The fungal species Cryptococcus neoformans and Cryptococcus gattii cause respiratory and neurological disease in animals and humans following inhalation of basidiospores or desiccated yeast cells from the environment. Sexual ... -
Red blood cell phenotype fidelity following glycerol cryopreservation optimized for research purposes.
(PloS one, 2018-01)Intact red blood cells (RBCs) are required for phenotypic analyses. In order to allow separation (time and location) between subject encounter and sample analysis, we developed a research-specific RBC cryopreservation protocol ... -
Release of outer membrane vesicles by Gram-negative bacteria is a novel envelope stress response.
(Mol Microbiol, 2007-01)Conditions that impair protein folding in the Gram-negative bacterial envelope cause stress. The destabilizing effects of stress in this compartment are recognized and countered by a number of signal transduction mechanisms. ... -
Simultaneous two-wavelength transmission quantitative phase microscopy with a color camera.
(Opt Lett, 2010-08-01)We present a quantitative phase microscopy method that uses a Bayer mosaic color camera to simultaneously acquire off-axis interferograms in transmission mode at two distinct wavelengths. Wrapped phase information is processed ... -
The effect of nitric oxide surface flux on the foreign body response to subcutaneous implants.
(Biomaterials, 2012-09)Although the release of nitric oxide (NO) from biomaterials has been shown to reduce the foreign body response (FBR), the optimal NO release kinetics and doses remain unknown. Herein, polyurethane-coated wire substrates ...
