(4) We also show that proliferation of primary amnion cells is not dependent on a high c-fos expression, suggesting that the function of c-fos is more likely to be associated with other cellular functions in the differentiated amnion cell.
(5) Injection of resistant mice with Salmonella typhimurium did not result in the induction of a population of macrophages that expressed I-A continuously.
(6) Stimulation is also observed with mixtures of APC expressing DPw3 and APC expressing A1, and likewise, DPw3+ APC become stimulatory when preincubated with supernatants from A1-positive cells.
(7) BL6 mouse melanoma cells lack detectable H-2Kb and had low levels of expression of H-2Db Ag.
(8) These studies show that metabolic activation is necessary for the expression of the mutagenic activity of aflatoxins B1 and G1 in N. crassa.
(9) We also show that the gene of the main capsid protein is expressed from its own promoter in an Escherichia coli strain.
(10) Using the oocyte system to express size-fractionated mRNA, we have also determined that the mRNA coding for this protein is between 1.9-2.4 kilobases in length.
(11) Because many wnt genes are also expressed in the lung, we have examined whether the wnt family member wnt-2 (irp) plays a role in lung development.
(12) A beta-adrenergic receptor cDNA cloned into a eukaryotic expression vector reliably induces high levels of beta-adrenergic receptor expression in 2-12% of COS cell colonies transfected with this plasmid after experimental conditions are optimized.
(13) Four other independent LCMV-GP2(275-289) specific H-2Db-restricted CTL clones also expressed V alpha 4 and V beta 10 gene elements.
(14) Maximal yields of lipid and aflatoxin were obtained with 30% glucose, whereas mold growth, expressed as dry weight, was maximal when the medium contained 10% glucose.
(15) Recent studies have shown that an aberration in platelet-derived growth factor gene expression is unlikely to be a factor in proliferation of smooth-muscle cells.
(16) Thus, human bronchial epithelial cells can express the IL-8 gene, with expression in response to the inflammatory mediator TNF regulated mainly at the transcriptional level, and with elements within the 5'-flanking region of the gene that are directly or indirectly modulated by the TNF signal.
(17) In concert with TF expressed by monocytes and macrophages this endothelial cell procoagulant activity may play a role in the pathogenesis of thrombotic disease.
(18) The possibility that both IL 2 production and IL 2R expression are autonomously activated early in T cell development, before acquisition of the CD3-TcR complex, led us to study the implication of alternative pathways of activation at this ontogenic stage.
(19) A domain containing a CA repeat, similar to ones found in other late, cAMP-induced Dictyostelium genes, is required for cAMP-induced and developmental expression.
(20) This study examines the role of sex hormones in modulating the expression of autoimmunity in NZB x NZW F1 mice.
Hypostasis
Definition:
(n.) That which forms the basis of anything; underlying principle; a concept or mental entity conceived or treated as an existing being or thing.
(n.) Substance; subsistence; essence; person; personality; -- used by the early theologians to denote any one of the three subdivisions of the Godhead, the Father, Son, and Holy Spirit.
(n.) Principle; an element; -- used by the alchemists in speaking of salt, sulphur, and mercury, which they considered as the three principles of all material bodies.
(n.) That which is deposited at the bottom of a fluid; sediment.
Example Sentences:

(2) It seems probable that colouration of the teeth would be found in those regions of the jaws where the blood is seeking on the basis of gravitation hypostasis.
(3) Hypostasis in the head and neck occurred more rapidly and intensively the deeper the cranial parts of the body were placed.
(4) The primary red colouration is most likely due to haemoglobin derivatives within the necrotic pulp tissue in cases in which blood has accumulated in the head and the dependent lividity (hypostasis) is obstructed.
(5) Five other cases were distinguished by linear marks indicating the water level, and in 10 cases a peculiar restriction of the postmortem hypostasis on the submersed areas could be seen.
(6) Epistasis-hypostasis interactions take place between genes of SU and SR complexes.
