A Role for RAS in V-CRK Transformation
… (CEF). Because of this similarity to v-Src transformation and EGF receptor (EGFR) stimulation, signalling pathways that might be activated in v-Crk transformed cells were investigated by analogy to pathways utilized by v-Src and the activated EGFR, and a search for serine/threonine kinases …

Structure-property relationships in novel ionomers
… of the 9 mol % PtBMA-PBD triblock produces a morphological transformation from unoriented rodlike domains to ionic spheroids.

Spatial correlation of lipid phase fluctuations in model membranes studied with two-photon fluorescence microscopy
… High hydrostatic pressure was used to induce morphological transformation of the GUVs and study the coupling between mechanical stress and phase behavior of the membrane. The ability to visualize the morphological and phase behavior of single GUVs under the microscope has allowed studying the …

Gamma frequency entrainment attenuates amyloid load and modifies microglia
… of microglia specific genes associated with morphological transformation of microglia and increased A[beta] phagocytosis by microglia. Inspired by these observations, we designed a non-invasive light-flickering paradigm that induced 40 Hz activity in visual cortex. The light-flickering …

The role of 4-hydroxynonenal in cellular signaling mechanisms
… of hGSTA4 in HLE B-3, cells underwent a morphological transformation becoming smaller and rounded, and lost anchorage dependence. Additionally they were observed to divide much more rapidly and acquired resistance to apoptosis via oxidative stress. In an attempt to provide a mechanistic …

Crumpled Graphene Oxide: Aerosol Synthesis and Environmental Applications
… such as TiO2, magnetite, and silver. Morphological transformation by crumpling, increased degree(s) of oxidation, and presence of natural organic matters act to enhance the stability of GO in water. CGO-TiO2 composites are shown to possess superior aqueous-based photocatalytic …

Evaluation of the effect of urbanization on urban thermal behaviour using urban heat island indicators: the case of the CBD of Accra.
… is aggravated by climate change. Several urban morphological factors can potentially modify urban climate and, consequently, the potential energy demand and supply in cities. Since independence, Ghana has experienced a significant rise in population growth, which has culminated in the …

The regulation of the CAMP signalling pathway in the human pathogenic fungus, Paracoccidioides brasiliensis
… is a thermally dimorphic fungus which undergoes morphological changes from a mycelial form at 26°C (environment) to a pathogenic yeast form at 37°C (human body) after inhalation of spores/conidia into the lungs of a human host (Nemecek et al., 2006). The cAMP pathway controls this morphological …

Synthesis and Characterization of Protein-Polymer Core-Shell Structures
… self-assembly process of TMV-P4VP structures, morphological transformation and TMV deformation were observed. The results confirmed that TMVs can stabilize the P4VP particles in water by covering their exterior surface. Meanwhile, the method can be used to assemble M13 and Au nanorods. This …

An investigation into the ultrastructural parameters of abdominal muscles in children and adolescents with spastic type cerebral palsy and the effect on postural muscle performance
… PCI may not be a useful test in determining the morphological transformation taking place in a muscle or muscle groups. The MAP's of the unaffected side of the abdominal muscles of the STCP individuals with hemiplegia showed similar characteristics to those of TD individuals. The STCP adversely …

Stressed Astrocytes: Insights on the Pathology of Alexander Disease
… patients. Astrocytes undergo severe morphological changes, beyond that of typical reactive astrocytes, and develop several forms of cell stress. However, how stressed astrocytes cause the loss of myelin in this disease is unknown. In this work I have conducted a largely …

The influences of dark matter halo formation history on black hole growth, circumgalactic gas expulsion and galaxy evolution
… the properties of the CGM and the quenching and morphological evolution of central galaxies in both the EAGLE and IllustrisTNG simulations. The simulations yield very different median CGM mass fractions as a function of halo mass, with low-mass haloes being significantly more gas-rich in …

Differential progression of pancreatic premalignancy in geographically distant murine transgenic cohorts uncovers key role of microbial metabolites
… premalignancy, we examined the rate of transformation of pancreatic explanted acinar cells to ductal-like structures. Following the addition of succinic acid or succinic acid producing bacteria, we observed a significant increase in morphological transformation. This increase in …

EXPLORING TRANSFORMATION OF STREET LAYOUT IN THE OLD CITY OF BEIJING: CASE STUDIES OF QIANMEN AND XISI
… and the process of their formation and transformation. The study seeks to understand the spatial structure and character of a metropolitan area by examining the patterns of its component parts and the process of its evolution. In particular, street pattern and route structure are the …
