Localization of the murine cholecystokinin A and B receptor genes
(Springer-Verlag, 1995-04)
We have determined the chromosomal locations of the two cholecystokinin (CCK) receptor genes in the mouse. Genetic localization utilized an interspecific backcross panel formed from the cross (C57BL/6J x Mus spretus ) F 1 ...
Ultrastructure and cell-cell coupling of cardiac myocytes differentiating in embryonic stem cell cultures
(John Wiley & Sons, Inc., 1997)
Differentiation cultures of embryonic stem (ES) cells can be a useful in vitro system for understanding cardiac myocyte development. However, cell morphometry, sarcomere development, and functional cell-cell junction ...
Glutamine Uptake at the Blood-Brain Barrier Is Mediated by N-System Transport
(Blackwell Science Ltd, 1998-12)
The mechanism of unidirectional transport of glutamine from blood to brain in pentobarbital-anesthetized rats was examined using in situ perfusion. Amino acid uptake into brain across the blood-brain barrier (BBB) is ...
Photoperiodic requirements for timing onset and duration of the breeding season of the ewe: Synchronization of an endogenous rhythm of reproduction
(Springer-Verlag, 1990-04)
A study was conducted to test the hypothesis that different portions of the annual photoperiodic cycle play different roles in timing the breeding season of the ewe, Ovis aries , an animal in which an endogenous rhythm ...
The human ZBP-89 homolog, located at Chromosome 3q21, represses gastrin gene expression
(Springer-Verlag; Springer-Verlag New York Inc., 1998-02)
TECHNICAL REPORT: Rapid confirmation of gene targeting in embryonic stem cells using two long-range PCR techniques
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1998-03)
Gene targeting in mouse embryonic stem (ES) cells generally includes the analysis of numerous colonies to identify a few with mutations resulting from homologous recombination with a targeting vector. Thus, simple and ...
Endothelin increases [Ca2+]i in rat pancreatic acinar cells by intracellular release but fails to increase amylase secretion
(Elsevier, 1992-08-12)
In individual fura-2 loaded cells of rat pancreatic acini endothelin-1 (ET-1) (10-50 nM) induced sustained oscillations in [Ca2+]i. At higher concentrations a larger, but transient increase in [Ca2+]i was observed, which ...
A simplified organ donor model produced by permanent complete central nervous system ischemia in dogs
(Elsevier, 1991-03)
The physiologic and pathophysiologic changes of the potential organ donor in the brain-dead state are poorly understood. We have developed a canine model of complete brain death by infusing saline into the subdural space ...
Targeted disruption of the mouse villin gene does not impair the morphogenesis of microvilli
(John Wiley & Sons, Inc., 1998-01)
The small intestine is functionally dependent on the presence of the brush border, a tightly packed array of microvilli that forms the amplified apical surface of absorptive cells. In the core of each microvillus, actin ...
