Comparison of quantification methods to measure fire-derived (black/elemental) carbon in soils and sediments using reference materials from soil, water, sediment and the atmosphere
(2007)
Black carbon (BC), the product of incomplete combustion of fossil fuels and biomass (called elemental carbon (EC) in atmospheric sciences), was quantified in 12 different materials by 17 laboratories from different ...
Did an ancient chlamydial endosymbiosis facilitate the establishment of primary plastids?
(East Carolina University, 2007-06)
Background: Ancient endosymbioses are responsible for the origins of mitochondria and plastids, and they contribute to the divergence of several major eukaryotic groups. Although chlamydiae, a group of obligate intracellular ...
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 ...
Levels of Ca2+-Dipicolinic Acid in Individual Bacillus Spores Determined Using Microfluidic Raman Tweezers
(East Carolina University, 2007-07)
Pyridine-2,6-dicarboxylic acid (dipicolinic acid [DPA]) in a 1:1 chelate with calcium ion (Ca-DPA) comprises 5 to 15% of the dry weight of spores of Bacillus species. Ca-DPA is important in spore resistance to many ...
Versican Expression during Synovial Joint Morphogenesis
(East Carolina University, 2007-09)
The extracellular matrix (ECM) plays a critical role in governing cell behavior and phenotype during limb skeletogenesis. Chondroitin sulfate proteoglycans (Cspgs) are highly expressed in the ECM of precartilage mesenchymal ...
