Nucleation and growth of Pd on cleaved MgO(001) surfaces were studied by variable-temperature atomic force microscopy in the temperature range 200-800 K. Constant island densities (similar to 3x10(12)cm(-2)) were observed over a wide temperature range, ind ...
Regulation of calbindin and calretinin expression by brain-derived neurotrophic factor (BDNF) was examined in primary cultures of cortical neurons using immunocytochemistry and northern blot analysis. Here we report that regulation of calretinin expression ...
The goal of this work was to develop a growth factor delivery system for use in nerve regeneration that would provide localized release of beta-nerve growth factor (b-NGF) and other members of the neurotrophin family in a controlled manner. Although b-NGF ...
The present work was performed to determine the ability of neurotrophic factors to allow axonal regeneration across a 15-mm-long gap in the rat sciatic nerve. Synthetic nerve guidance channels slowly releasing NGF and GDNF were fabricated and sutured to th ...
Crabtree neg. organisms such as Kluyveromyces, Pichia, Hansenula and Candida, are used to make selected org. products such as lactic acid. The organisms are cultured in a first culture medium that includes glucose, under conditions that promote cellular re ...
Dorsal roots have a limited regeneration capacity after transection. To improve nerve regeneration, the growth-promoting effects of the neurotrophins nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and neurotrophin-3 (NT-3) were evalua ...
Neural stem cells (NSCs), when stimulated with epidermal growth factor (EGF) or fibroblast growth factor-2 (FGF-2), have the capacity to renew, expand, and produce precursors for neurons, astrocytes, and oligodendrocytes. We postulated that the early appea ...
A novel method for the delivery of growth factor proteins from fibrin matrixes was developed. Nerve growth factor (NGF) fusion proteins contg. an exogenous transglutaminase substrate at the N-terminus of the protein were made recombinantly by E. coli. The ...
Biomimetic polymer gels have been developed to display the key features of the extracellular matrix, namely presentation of adhesion sites, presentation of growth factor binding sites and release, and ability to be remodeled by cell-assocd. proteases. [on ...
Airway smooth muscle constriction leads to the development of compressive stress on bronchial epithelial cells. Normal human bronchial epithelial cells exposed to an apical-to-basal transcellular pressure difference equivalent to the computed stress in the ...
