Predictions for oxygen supply control to enhance population stability of engineered production strains
(Wiley Subscription Services, Inc., A Wiley Company, 1994-02-20)
The simultaneous growth and product formation in a microbial culture is an important feature of several laboratory, industrial, and environmental bioprocesses. Metabolic burden associated with product formation in these ...
Adhesion at a heterophase interface: First-principles study of Mo(001)/MoSi 2 (001)
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-09)
The bonding characteristics, interfacial energetics, and electronic structure associated with adhesion at the Mo-MoSi 2 (001) heterophase interface are investigated using the first-principles, self-consistent local orbital ...
High-density algal photobioreactors using light-emitting diodes
(Wiley Subscription Services, Inc., A Wiley Company, 1994-11-20)
Lack of high-density algal photobioreactors (PBR) has been a limitation in exploiting the biotechnological potential of algae. Recent developments of highly efficient light-emitting diodes (LED using gallium aluminum ...
H2O2-Induced Increases in Cellular F-Actin Occur without Increases in Actin Nucleation Activity
(Elsevier, 1994-02)
Previous work has shown that H2O2 causes an increase in polymerized actin (F-actin) inside cells. To test the hypothesis that increased polymerization resulted from a mechanism involving increased actin nucleation activity, ...
Molybdenum nitride catalysts : I. Influence of the synthesis factors on structural properties
(Elsevier, 1994-03)
Effects of the synthesis parameters on the structural properties of molybdenum nitride catalysts, prepared by the temperature-programmed reaction of MoO3 with NH3, have been examined. Molybdenum trioxide was heated in ...
Effects of antimalarials and protease inhibitors on plasmodial hemozoin production
(Elsevier, 1994-10)
Malarial hemozoin may play an important role as a target for antimalarial drugs and in disease pathogenesis. A new assay for hemozoin was developed in which the hemozoin was separated from cells by filtration. Trophozoites ...
The Role of the Hippocampal Mineralocorticoid and Glucocorticoid Receptors in the Hypothalamo-Pituitary-Adrenal Axis of the Aged Fisher Rat
(Elsevier, 1994-10)
The aging process has been frequently associated with hippocampal neuredegeneration, loss of corticosteroid receptors, and, at the same time, dysfunction of the hypothalamo-pituitary-adrenal (HPA) axis. We were interested ...
Direct Evidence for Homologous Sequences on the Paracentric Regions of Human Chromosome 1
(Elsevier, 1994-05-15)
Calcyclin is a member of the S100 family of proteins, many of which are encoded by genes that have been localized to the proximal long arm of human chromosome 1 (bands q21-q22). A 450-kb yeast artificial chromosome clone ...
Synthesis of a disulfide stabilized RNA hairpin
(Elsevier, 1994-03-14)
An N-3 ethylthiol-modified uridine has been synthesized and incorporated through solid-phase phosphoramidite chemistry at the 5'- and 3'-termini of an RNA hairpin to provide increased conformational stability via a disulfide ...
Homogenization theory and digital imaging: A basis for studying the mechanics and design principles of bone tissue
(Wiley Subscription Services, Inc., A Wiley Company, 1994-03-25)
Bone tissue is a complex multilevel composite which has the ability to sense ad respond to its mechanical environment. It is believed that bone cells called osteocytes within the bone matrix sense the mechanical environment ...
