Red cells preserved with 10% hydroxyethyl starch: Effect of prefreeze washing
(Elsevier, 1975-10)
Prefreeze washing of red cells with saline and other wash solutions before freezing with 10% hydroxyethyl starch does not yield an improved product after thawing. The saline stabilities and cell recoveries are reduced and ...
The preservation of erythrocytes at liquid nitrogen temperatures with hydroxyethyl starch: the removal of hydroxyethyl starch from erythrocytes after thawing
(Elsevier, 1971-12)
Packed human erythrocytes were frozen in liquid nitrogen using hydroxyethyl starch as a cryoprotective agent. Upon thawing, the cells were washed with a balanced salt solution. The washed cells were stable when resuspended ...
Beta decay and the origin of biological chirality: New experimental results
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1984-12)
The proposed connection between the parity-violating handedness of beta particles in radioactive decay and the sign (L) of biological chirality (the Vester-Ulbricht [V-U] hypothesis) is being investigated by measuring the ...
Interaction of infectious viral particles with a quaternary ammonium chlorid (QAC) surface
(Wiley Subscription Services, Inc., A Wiley Company, 1989-08-20)
The antiviral activity of a surface-bonded quaternary ammonium chloride (QAC) was examined in this study. The mechanism of inactivation was elucidated by a combination of infectivity assay, radioactive labeling assay, and ...
Leuconostoc mesenteroides growth kinetics with application to bacterial profile modification
(Wiley Subscription Services, Inc., A Wiley Company, 1994-04-15)
Bacterial profile modification (BPM) is being developed as an oil recovery technique that uses bacteria to selectively plug oil depleted zones within a reservoir to divert displacing fluids (typically water) into oil-rich ...
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 ...
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 ...
Biochemical systems theory and metabolic control theory: 1. fundamental similarities and differences
(Elsevier, 1987-10)
Biochemical Systems Theory (BST) was developed in the late 1960s to explicate the integrated behavior of intact biochemical systems--specific dynamic behavior as well as general principles of design--in relation to the ...
A probability measure for character compatibility
(Elsevier, 1981-11)
It is proved that two undirected binary cladistic characters are compatible iff their smaller states are disjoint or one is a subset of the other. The concept of a cladistic character as an ordered tree of subsets is ...
