Use of Cyclodextrin-Cholesterol Complex as a Primary Standard in Cholesterol Analysis
(Elsevier, 1993-06)
Cholesterol is an analyte commonly measured in various biological fluids. Enzymic procedures have virtually replaced the chemical methods for cholesterol determinations. Standardization of cholesterol assays often involve ...
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 ...
Protein tyrosine phosphatases in disease processes
(Elsevier, 1994-12)
Given the importance of tyrosine phosphorylation of proteins in signalling pathways, it is perhaps not surprising that protein tyrosine phosphatases (PTPs) are involved in the pathogenesis of certain human diseases. A PTP ...
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 ...
Histamine and cis-urocanic acid augment tumor necrosis factor-alpha mediated induction of keratinocyte intercellular adhesion molecule-1 expression
(Wiley Subscription Services, Inc., A Wiley Company, 1993-08)
Early cellular and molecular events in inflamed skin include the active participation of epidermal keratinocytes (KCs) and dermal mast cells which can produce diffusible mediators such as tumor necrosis factor-alpha (TNF-Α), ...
A Ser/Thr-rich multicopy suppressor of a cdc24 bud emergence defect
(John Wiley & Sons, Ltd., 1992-04)
MSB2 was identified previously as a multicopy suppressor of a temerature-sensitive mutation in CDC24 , a gene required for polarity establishment and bud formation in Saccharomyces cerevisiae . The inferred MSB2 product ...
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 ...
Protein tyrosine phosphatases: characterization of extracellular and intracellular domains
(Elsevier, 1994-02)
Protein tyrosine phosphatases (PTPs) play an important role in the regulation of cell growth and differentiation. With over 30 PTPs identified, the specific functions of these enzymes are now being addressed. The identification ...
