Resource heterogeneity and community structure: A case study in Heliconia imbricata Phytotelmata
(Springer-Verlag, 1990-08)
Complex or non-additive differences in the distribution and abundance of arthropod species inhabiting the water-filled bracts of Heliconia imbricata can be created by simple manipulations of resource levels. The primary ...
Role of CFTR in lysosome acidification
(Elsevier, 1992-04-15)
The role of CFTR in lysosome acidification was examined in CFPAC-1 pancreatic adenocarcinoma cells with the [Delta]F508 mutation that were transduced with a retroviral vector (PLJ-CFPAC) or with the normal CFTR gene ...
DNA insertions distinguish the duplicated renin genes of DBA/2 and M. hortulanus mice
(Springer-Verlag, 1991-03)
In a survey of inbred and wild mouse DNAs for genetic variation at the duplicate renin loci, Ren-1 and Ren-2 , a variant Not I hybridization pattern was observed in the wild mouse M. hortulanus . To determine the basis for ...
Chromosomal localization of the zinc finger protein 15, Zfp15 , on Mouse Chromosome 4
(Springer-Verlag, 1995-04)
The human ZBP-89 homolog, located at Chromosome 3q21, represses gastrin gene expression
(Springer-Verlag; Springer-Verlag New York Inc., 1998-02)
High-Resolution Detection of Five Frequencies in a Single 3D Spectrum: HNHCACO - a Bidirectional Coherence Transfer Experiment
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-02)
A new triple-resonance pulse sequence, 3D HNHCACO, is introduced and discussed, which identifies sequential correlations of the backbone nuclei (Hα(i-1), Cα(i-1), C′(i-1), NH(i)) of doubly labeled proteins in H2O. The ...
pH-Dependent Decarboxylation of 2-Amino-3-ketobutyrate, the Unstable Intermediate in the Threonine Dehydrogenase-Initiated Pathway for Threonine Utilization
(Elsevier, 1993-02-15)
2-Amino-3-ketobutyrate can be readily formed enzymatically by the action of L-threonine dehydrogenase. A convenient assay for determining the half-life of this [beta]-keto acid is afforded by its rapid and quantitative ...
Milk composition and lactational output in the greater spear-nosed bat, Phyllostomus hastatus
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-07)
Growth rates of mammalian young are closely linked to the ability of the mother to provide nutrients; thus, milk composition and yield provide a direct measure of maternal investment during lactation in many mammals. We ...
Genetic and physical characterization of a region of Arabidopsis chromosome 1 containing the CLAVATA1 gene
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-01)
With the advance of Arabidopsis as a model system for understanding plant genetics, development and biochemistry, a detailed description of the genome is necessary. As such, focused projects are underway to map and sequence ...
