Expression patterns of neurotrophic factor mRNAs in developing human teeth
(Springer-Verlag, 2002-11)
Neurotrophic factors regulate survival, differentiation, growth and plasticity in the nervous system. In addition, based on their specific and shifting temporospatial expression patterns, neurotrophic factors have been ...
Dynorphin (1-17): Lack of analgesia but evidence for non-opiate electrophysiological and motor effects
(Elsevier, 2006-04-07)
Dynorphin and an opiate-inactive fragment des-Tyr-dynorphin produced similar effects on EEG, motor function and hippocampal unit firing. Naloxone had no effect on the actions of dynorphin in these systems and dynorphin ...
ENHANCER of TRY and CPC 2 ( ETC2 ) reveals redundancy in the region-specific control of trichome development of Arabidopsis
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-05)
>An evolutionarily conserved set of proteins consisting of MYB and bHLH transcription factors and a WD40 domain protein is known to act in concert to control various developmental processes including trichome and root hair ...
Microbial community utilization of recalcitrant and simple carbon compounds: impact of oak-woodland plant communities
(Springer-Verlag, 2004-01)
Little is known about how the structure of microbial communities impacts carbon cycling or how soil microbial community composition mediates plant effects on C-decomposition processes. We examined the degradation of four ...
Determining the sources of calcium for migratory songbirds using stable strontium isotopes
(Springer-Verlag, 2001-02)
We investigated natural variations in the stable isotopic composition of strontium (a surrogate for calcium) in the bones of a single species of breeding migratory songbird, as well as in their eggshells, egg contents, and ...
Genetic mapping and molecular characterization of the self-incompatibility ( S ) locus in Petunia inflata
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-11)
Gametophytic self-incompatibility (SI) possessed by the Solanaceae is controlled by a highly polymorphic locus called the S locus. The S locus contains two linked genes, S-RNase , which determines female specificity, and ...
Fine root chemistry and decomposition in model communities of north-temperate tree species show little response to elevated atmospheric CO 2 and varying soil resource availability
(Springer-Verlag, 2005-12)
Rising atmospheric [CO 2 ] has the potential to alter soil carbon (C) cycling by increasing the content of recalcitrant constituents in plant litter, thereby decreasing rates of decomposition. Because fine root turnover ...
Origin and evolution of the vertebrate vomeronasal system viewed through system-specific genes
(Wiley Subscription Services, Inc., A Wiley Company, 2006-07)
Tetrapods have two distinct nasal chemosensory systems, the main olfactory system and the vomeronasal system (VNS). Defined by certain morphological components, the main olfactory system is present in all groups of ...
Microbial community composition and function beneath temperate trees exposed to elevated atmospheric carbon dioxide and ozone
(Springer-Verlag, 2002-04)
We hypothesized that changes in plant growth resulting from atmospheric CO 2 and O 3 enrichment would alter the flow of C through soil food webs and that this effect would vary with tree species. To test this idea, we ...
Microbial Community Structure and Oxidative Enzyme Activity in Nitrogen-amended North Temperate Forest Soils
(Springer-Verlag; Spreinger-Verlag, 2004-10)
Large regions of temperate forest are subject to elevated atmospheric nitrogen (N) deposition which can affect soil organic matter dynamics by altering mass loss rates, soil respiration, and dissolved organic matter ...
