Laser tweezers and Raman spectroscopy systems and methods for the study of microscopic particles
(2005-05-24)
Methods and systems for studying microscopic particles are provided. An optical trap for a selected microscopic particle can be formed with a laser beam at a first power level. The laser beam can have a variable power level ...
Wurster's crown ligands
(2001-07-17)
Wurster's crown ligands comprise a macrocyclic ligand such as a crown ether in which a hetero atom is substituted with a 1,4-phenylenediamine group. The phenylenediamine group is covalently bound to the macrocyclic ligand ...
Tissue lockable connecting structures
(2006-08-01)
Percutaneous skin access devices include a plurality of locked connecting units mounted to the exterior surface of an implantable medical object which, in position, is configured to penetrate the skin of a subject. The ...
Catabolite repression control (Crc) gene and Pseudomonas virulence
(2004-11-30)
The present invention relates to a method of screening for compounds that inhibit the virulence of Pseudomonas bacteria and comprises the steps of: providing a culture medium comprising Pseudomonas bacteria, administering ...
Review of microdialysis in brain tumors, from concept to application: First Annual Carolyn Frye-Halloran Symposium
(East Carolina University, 2004-01)
In individuals with brain tumors, pharmacodynamic and pharmacokinetic studies of therapeutic agents have historically used analyses of drug concentrations in serum or cerebrospinal fluid, which unfortunately do not necessarily ...
Gamma Protocadherin Expression in the Embryonic Chick Nervous System
(East Carolina University, 2007)
Protocadherin gamma (pcdh-gamma) family expression was examined in the embryonic chick central nervous system by in situ hybridization. Transcripts were visualized in discrete regions of fore-, mid-, and hindbrain at stages ...
Pubic Lice (Pthirus pubis): History, Biology and Treatment vs. Knowledge and Beliefs of US College Students
(East Carolina University, 2009-02)
Pubic lice (Pthirus pubis) maintain a worldwide parasitic population infesting two to over 10 percent of human populations, continuing a presence that has been constant since early evidence 10,000 years ago. Outbreaks in ...
Footprints in the sand: independent reduction of subdigital lamellae in the Namib–Kalahari burrowing geckos
(East Carolina University, 2006-04-07)
Many desert organisms exhibit convergence, and certain physical factors such as windblown sands have generated remarkably similar ecomorphs across divergent lineages. The burrowing geckos Colopus, Chondrodactylus and ...
Molecular phylogenetic evidence for a mimetic radiation in Peruvian poison frogs supports a Müllerian mimicry hypothesis.
(East Carolina University, 2001-12-07)
Examples of Müllerian mimicry, in which resemblance between unpalatable species confers mutual benefit, are rare in vertebrates. Strong comparative evidence for mimicry is found when the colour and pattern of a single ...
Desired Versus Actual Training for Online Instructors in Community Colleges
(East Carolina University, 2009)
The growth of distance education and the demand for instructors has developed over the past ten to fifteen years. There is a perception that the type and amount of instructor preparation is highly variable between institutions. ...
