Transcriptional regulation during T-cell development: the [alpha] TCR gene as a molecular model
(Elsevier, 1992)
The regulation of gene expression during lymphocyte differentiation is a complex process involving interactions between multiple positive and negative transcriptional regulatory elements. In this article, transcriptional ...
Effect of Neuropeptide Y on Natural Killer Activity of Normal Human Lymphocytes
(Elsevier, 1993-03)
The in vitro effect of neuropeptide Y (NPY) on natural killer (NK) cell activities of normal lymphocytes was investigated. NPY at 10-9 to 10-12M concentrations produced significant suppression of NK activity against K 562 ...
Cytogenetic analysis of posterior uveal melanoma
(Elsevier, 1993-03)
Cytogenetic analysis was performed on short-term cultures of primary tumor samples from seven patients with posterior uveal melanoma. Informative data were obtained from four patients, all of whom had a near-diploid ...
The effects of exopolymers on cell morphology and culturability of Leuconostoc mesenteroides during starvation
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-11)
Biofilm formation by bacterial cells can be used to modify the subsurface permeability for the purpose of microbial enhanced oil recovery, bio-barrier formation, and in situ bioremediation. Once injected into the subsurface, ...
A dual function activity-dependent, muscle-specific enhancer from rat nicotinic acetylcholine receptor δ-subunit gene
(John Wiley & Sons, Inc., 1996-11)
Nicotinic acetylcholine receptors (nAChR) mediate communication between nerve and muscle. The expression of these receptors increases dramatically during muscle development when myoblasts are fusing into multinucleated ...
On-line multichannel Raman spectroscopic detection system for capillary zone electrophoresis
(Elsevier, 1991)
An on-line multichannel Raman spectroscopic detection system for capillary zone electrophoresis using a charge-coupled device as the detector is described. Resonant, near-resonant and non-resonant excitation Raman ...
CCK antagonists reveal that CCK-8 and JMV-180 interact with different sites on the rat pancreatic acinar cell CCKA receptor
(Elsevier, 1994)
The ability of CCKA antagonists to inhibit full and partial CCK agonists of the rat pancreatic acinar cell CCKA receptor has been studied. When isolated rat pancreatic acini were superfused with CCK-8 (10 pM-1 nM) or CCK-4 ...
Receptor Binding Techniques
(Wiley Periodicals, Inc.Elsevier/North‐Holland Biomedical Press, 1997-09)
This overview first discusses issues relating to the selection of radioligand for receptor binding assays, including the isotopic label and considerations pertaining to the pharmacological and chemical profile of the ligand. ...
Intracellular partitioning of androgen receptor immunoreactivity in the brain of the male syrian hamster: Effects of castration and steroid replacement
(Wiley Subscription Services, Inc., A Wiley Company, 1993-07)
The effect of castration and steroid replacement on the intracellular partitioning of the androgen receptor in the brain of the male Syrian hamster was determined using immunocytochemistry. Androgen receptors were visualized ...
Predictors of Mammography Use in the Past Year among Elderly Women
(Sage Publications, 1997)
Thirty-two personal characteristics were examined as potential predictors of mammography use in the past year in a geriatric clinic. Interviews assessed demographic, health status, health service utilization, health belief, ...
