The parietal cell is transformed morphologically when acid secretion is stimulated. The tubulovesicuiar membranes, prominent in the resting cell, diminish, whereas there is a marked increase in the apical plasma membrane (the secretory surface of the cell) together with the appearance of long apical microvilli. 

Identification of Molecular Target Because geldanamycin reverses transformed morphology of v-xrc-transformed fibroblasts without inhibiting in vitro p60 kinase activity, it was thought that the molecular target of the compound was not p60 . To identify the target protein, Whitesell et al. prepared the... 

Herbimycin was found to have potent herbicidal activity against most mono- and dicotyledonous plants, especially against Cyperus microiria STEUD but strong resistance by Oryza saliva [173]. It was also reported that herbimycins showed cytocidal activity on both HeLa cells and Ehrlich cells in vitro and could convert the transformed morphology of Rous sarcoma virus-infected rat kidney cells to the normal ones [177]. However, interest in geldanamycin and herbimycin increased greatly upon the discovery of their potent antitumor activity at nanomolar concentrations [178, 179]. 

As the substrate temperature increases, the surface mobUity increases and the stmctural morphology first transforms to that of Zone T, ie, tightly packed fibrous grains having weak grain boundaries, and then to a full density columnar morphology corresponding to Zone 2 (see Fig. 7). 

The normal rat kidney (NRK) cell line is an untransformed cell line established from rat kidney cells. However, when NRK cells are treated with both TGF alpha and TGF beta, the cells assume a transformed phenotype. In addition to exhibiting an altered morphology in monolayer culture, NRK cells possess the capacity for anchorage-independent growth while being treated with both TGF alpha and TGF... 

This is a nonpolar rubber with very little unsamration. Nanoclays as well as nanotubes have been used to prepare nanocomposites of ethylene-propylene-diene monomer (EPDM) rubber. The work mostly covers the preparation and characterization of these nanocomposites. Different processing conditions, morphology, and mechanical properties have been smdied [61-64]. Acharya et al. [61] have prepared and characterized the EPDM-based organo-nanoclay composites by X-ray diffracto-gram (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy... 

SEES with oil leads to the transition from lamellar morphology to micellar morphology [15]. This transformation is reflected in the above images of pure SEES and its SEES/oil = 60 40 composition. The loading leads to an increase of the structural factor from 21 to 53 nm. Therefore, the incorporation of oil to ethylene-butylene blocks induced larger separation of micelles formed predominantly by styrene blocks. 

Fourier Transform (FT) Ranun spectroscopy (Model RFS 100/S, BRUKER Co.) using ND YAG laser was used to analyze the products on their structure electronic and vibration properties. The morphology of CNTs was observed by scanning dartron microscopy (SEM, Model S-4200, Hitach Co.) and transmission electron microscope (TEM, Modd JEOL 2000FX-ASID/EDS, Philips Co.).
