Foraging behavior as a determinant of asymmetric competitive interaction between two ant species in a tropical agroecosystem
(Springer-Verlag, 1994-07)
This work is concerned with elucidating competitive interactions between two neotropical ants, Solenopsis geminata and Pheidole radoszkowskii , focusing on their foraging behavior. When released from competition from P. ...
Neurofibromatosis type 1 gene product (neurofibromin) associates with microtubules
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1993-05)
The neurofibromatosis type 1 (NF1) gene was recently identified by positional cloning and found to encode a protein with structural and functional homology to mammalian and yeast GTPase-activating proteins (GAPs). Using ...
Conversion to Ca2+-Independent Form of Ca2+/Calmodulin Protein Kinase II in Rat Pancreatic Acini
(Elsevier, 1994-02-28)
CCK rapidly converted Ca2+/calmodulin kinase II (CaMK II) to a Ca(2+)-independent form with peak action at 30 sec followed by decline to the basal level at 10 min. The threshold concentration of CCK for this action was 30 ...
Identification of genes within the Krd deletion on mouse Chromosome 19
(Springer-Verlag; Springer-Verlag New York Inc., 1999-04)
Redistribution of 5-Lipoxygenase and Cytosolic Phospholipase A2 to the Nuclear Fraction upon Macrophage Activation
(Elsevier, 1993-10-15)
Both the cytosolic phospholipase A2 and 5-lipoxygenase enzymes redistribute from the high-speed supernatant to a particulate fraction upon cell activation with associated leukotriene synthesis, but the subcellular site to ...
Stimulation of myenteric plexus neurite outgrowth by insulin and insulin-like growth factors I and II
(Elsevier, 1992)
A defined culture medium containing insulin, insulin-like growth factor I (IGF-I) or insulin-like growth II (IGF-II) supported morphological development of myenteric plexus neurons derived from neonatal guinea pigs. Insulin ...
The genes for the inter-α-inhibitor family share a homologous organization in human and mouse
(Springer-Verlag, 1992-12)
Inter-α-inhibitor ( IαI ) and related molecules in human are comprised of three evolutionarily related, heavy (H) chains and one light (L) chain, also termed bikunin. The latter originates from a precursor molecule that ...
Expression of carbonic anhydrase II (CA II) promoter-reporter fusion genes in multiple tissues of transgenic mice does not replicate normal patterns of expression indicating complexity of CA II regulation in vivo
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1995-12)
Although the proximal, 5′ 115 bp of the human carbonic anhydrase II (CA II) gene was sufficient for expression of a reporter gene in some transfected cell lines, we found previously that 1100 bp of this promoter (or 500 ...
The Gunnera symbiosis: DNA restriction fragment length polymorphism and protein comparisons of Nostoc symbionts
(Springer-Verlag; Springer-Verlag New York Inc., 1990-05)
Cyanobacteria separated from symbiosis with several species of the angiosperm Gunnera were comparatively characterized and correlated with the locales and taxonomy of their host plants. All were identified as strains of ...
Coordinate control and variation in X-linked gene expression among female mice
(Springer-Verlag; Springer-Verlag New York Inc., 1997-11)
In normal female mammals, one of the two X Chromosome (Chr) homologs per cell is silenced coordinately during early embryogenesis. The genes located on the inactivated X homolog are predicted to be influenced by the same ...
