High levels of non-activated receptors in glucocorticoid-sensitive S49wt mouse lymphoma cells incubated with dexamethasone
(Elsevier, 1994-10)
Upon agonist binding the heteromeric glucocorticoid receptor complex under goes a conformational change (receptor activation). This event involves the dissociation of a dimer of 90 kDa heat shock proteins. Whereas receptor ...
A radiation hybrid map of the proximal short arm of the human X chromosome spanning incontinentia pigmenti 1 (IP1) translocation breakpoints
(Elsevier, 1992-11)
Radiation hybrid mapping was used in combination with physical mapping techniques to order and estimate distances between 14 loci in the proximal region of the short arm of the human X chromosome. A panel of radiation ...
Interaction of linear manno-oligosaccharides with three mannose-specific bulb lectins. Comparison with mannose/glucose-binding lectins
(Elsevier, 1992-05-22)
Three new mannose-binding lectins, isolated from daffodil (NPA), amaryllis (HHA), and snowdrop (GNA) bulbs, are capable of precipitating with a linear mannopentaose (Man[alpha]1-3Man[alpha]1-3Man[alpha]1-3Man[alpha]1-2Man). ...
Localization of parathyroid enlargement: experience with technetium-99m methoxyisobutylisonitrile and thallium-201 scintigraphy, ultrasonography and computed tomography
(Springer-Verlag, 1994-01)
Technetium-99m methoxyisobutylisonitrile (MIBI), like thallium-201, has recently been introduced as a myocardial perfusion agent and is now also showing very promising results in parathyroid scintigrapy. The results of 201 ...
Characterization of gastrin amidation in the rat and porcine antrum: comparison with the pituitary
(Elsevier, 1990-04-24)
The formation of biologically active gastrin from glycine-extended processing intermediates occurs via the action of a peptide [alpha]-amidating enzyme. The observation that gastrin exists primarily as unamidated precursors ...
Fusion of mercury a new certified standard for differential scanning calorimetry
(Elsevier, 1990-03)
From the results of adiabatic-calorimetric measurements, mercury has been certified as a standard reference material for temperature and enthalpy of fusion for differential scanning calorimetry. The fusion temperature is ...
Rapid protein release from Escherichia coli by chemical permeabilization under fermentation conditions
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-25)
Overall protein release greater than 75% in less than 1 h can be attained by exposing exponentially growing Escherichia coli cells to 0.4 M guanidine plus 0.5% Triton X-100 at 37°C in medium. Cell growth stops immediately ...
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 ...
