(1) We have isolated several gamma-ray-induced mutants (GIMs) of the nontumorigenic HeLa x skin fibroblast hybrid CGL1 that were specifically selected for reexpression of IAP to further investigate the potential linkage between IAP regulation and the putative tumor suppressor locus.
(2) The relaxation rates of the exchangeable guanine imino protons (Gim) in H2O and in 90% D2O show that below 20 degrees C spin-lattice relaxation is exclusively from proton-proton magnetic dipolar interactions while proton-nitrogen interactions contribute about 30% to the spin-spin relaxation.
(3) These stimulate the processes of myeloid precursor proliferation directly (by means of lymphokines) and in cooperation with monocytes-macrophages of GIM.
(4) The relaxation rates of the Gim, C-H5, and C-H6 in B- and Z-form poly(dG-dC).poly(dG-dC) cannot be explained by assuming the DNA behaves as a rigid rod.
(5) Gonadotrophin-inhibiting material (GIM) was able to inhibit the binding of 125I-hCG to rat Leydig cells, suggesting that its inhibiting properties are due to its ability to complete for the hCG binding sites on Leydig cells.
(6) The observation that the spin-lattice relaxation is nonexponential and that the initial spin-lattice relaxation rate of the Gim, G-H8 and C-H6 protons depends on the selectivity of the exciting pulse shows that spin-diffusion dominates the spin-lattice relaxation.
(7) However, studies with tumor reconstitutes of the GIMs and transfection studies with an IAP complementary DNA expression vector indicate that high IAP expression alone is not sufficient to confer rapid tumor growth.
(8) Measurements of the 1H spin-lattice (R1) and spin-spin (R2) relaxation rates of the exchangeable thymine (Tim) and guanine (Gim) imino protons have been used to probe the internal dynamics of the B and Z-forms of poly[d(A-br5C).d(G-T)] and the mechanism of the B-Z transition.
(9) The GIMs have a wide range of cell morphology and level of IAP expression (nearly a factor of 40).
(10) The effect of GIM on hCG-induced adenylate cyclase activation and testosterone production was also studied.
(11) Conversion to the Z-form by addition of 4.5 M-NaCl dramatically reduces both the Tim and Gim exchange rates (estimated to be less than 2 s-1 at 70 degrees C).
(12) Binding of fluorescein isothiocyanate-tagged GIM to Leydig cells was also seen.
(13) The tumorigenicity of the GIMs was examined by s.c. injection into nude mice and all were found to be tumorigenic.
(14) The B and Z-forms of poly[d(A-br5C).d(G-T)] coexist in 4.6 M-NaCl at 45 degrees C. Due to slow exchange, two sets of Tim and Gim resonances are observed and can be assigned to the B and Z conformations (the chemical shifts are, respectively, Tim = 13.4, 14.1 p.p.m.
(15) In the second study a combination of music and imagery was examined by randomly assigning subjects to one of five groups: self-generated imagery with music (SIM), guided imagery with music (GIM), self-generated imagery without music (SI), guided imagery without music (GI), or no-treatment control.
(16) The tumor volume-doubling time is in the range of 4 to 8 days for all the cell lines; however, the lag time to reach 500 mm3 tumor volume was significantly longer when the GIM IAP activity was low (less than 20% relative activity), suggesting perhaps that there is a threshold level of IAP expression required for tumor formation and selection for high IAP expression in vivo.
(17) The increased number of committed precursor cells of erythro- and granulomonocytopoiesis, morphologically differentiated elements and enhancing colony-stimulating and erythropoietic activities of GIM cells origin were shown as well.
(18) At elevated temperature, R1 for both Tim and Gim in the B conformation is dominated by exchange with the solvent, with Tim exchanging more rapidly than Gim.
(1) It included antibodies against cytokeratin (CK), vimentin (VIM), glial fibrillary acidic protein (GFAP), and muscle-specific actin (MSA); the latter three markers are associated with myoepithelial differentiation.
(2) An in situ hybridization technique using a biotinylated probe for the human VIM was applied to detect eventual cryptic translocations, as chromosome 10p is difficult to identify.
(3) Most of these cells were also immunostained for VIM in adjacent semithin sections.
(4) According to our results, most astrocytes in the adult rat optic nerve showed coexpression of VIM and GFAP.
(5) The coordinate expression of the nuclear p53 protein, cytoplasmic intermediate filament vimentin (VIM) and membrane epidermal growth factor receptor (EGF-R) was significantly associated with oestrogen receptor immunocytochemical nuclear stain (ER-ICA) negative breast carcinomas.
(6) Immunostaining of glycosphingolipids isolated from myeloid cells demonstrated that the SSEA-1 epitope is carried by several neutral glycosphingolipids and that the VIM-2 epitope is carried by three or more gangliosides.
(7) A high frequency (130 Hz) chronic Vim stimulation was performed in 4 parkinsonian patients, 2 of them having previously undergone a thalamotomy on the other side.
(8) Through the development of an indirect coupled assay, we have identified three in vitro activities in the yeast Saccharomyces cerevisiae that can catalyze the proteolytic cleavage of the three COOH-terminal amino acids of the synthetic peptide substrate N-acetyl-KSKTK[S-farnesyl-Cys]VIM.
(9) Vim mRNA was not found in the fetal oral epithelia, dental lamina or the enamel organ, but a distinct immunoreactivity with monoclonal antibodies to Vim was seen in the stellate reticulum cells of the enamel organ.
(10) There was considerable overlap in the distribution of motor and sensory responses in the vicinity of the ventral intermediate (VIM) thalamus: however, motor responses, particularly irregular movements, tended to be confined within the VIM and ventro-oralis posterior (VOP), whereas sensory responses tended to be localized in the VIM and ventroposterolateral nuclei, with considerable extension into the ventroposterior subthalamic region.
(11) However, a major discrepancy existed for the expression of vimentin gene (VIM), which was high, even though the map location of the gene (10p) was missing in many cell lines.
(12) Two main populations were present: the major one being HLA-DR+, Cy mu+, VIM-D5+, TdT-, CALLA-, SmIg-; the minor one HLA-DR+, Cy mu+, VIM-D5-, TdT+, CALLA-, SmIg-.
(13) In hemangioblastomas, besides intervascular and endothelial cells, groups of polygonal cells are intensely positive for both VIM and GFAP.
(14) The significance of the coexpression VIM-GFAP and the restricted location of GFAP positive cells is discussed in relation with the maturation of pineal glial cells.
(15) Furthermore, the maturation of myeloid progenitor cells has been examined by delayed treatment with VIM-D5 and complement during the in vitro culture period.
(16) Both layers of the iris epithelium reacted with monoclonal antibodies (MAb) V9 and Vim 3B4 to vimentin, whereas the ciliary epithelia additionally reacted with MAb CAM 5.2, CK5, KS-B17.2, and CY-90, recognizing cytokeratins 8 and 18.
(17) As long ago as July 2007, Abbey's director of service quality, Vim Maru, told the Observer that "service has not been good enough", but its "action plan is on track".
(18) The VIM-D5 MoAb was used with rabbit complement (C'), whereas the 8.27 and SMY15A MoAbs were used in the presence of human C'.
(19) On the other side, a discrete lesion in Vim caused no sensory disturbance.
(20) After complement-mediated cytolysis with VIM-2, the number of BFU-e was significantly reduced; however, this effect was largely abrogated by addition of leukocyte-conditioned medium to the cultures as an exogenous source of burst-promoting activity.
