Sticky molecules in not-so-sticky cells
(Elsevier, 1991)
The assignment of specific roles to cell-surface proteins by standard methods can be a major problem. In the technique described below, Schneider-2 (S2) cells, an established Drosophila cell line, have been used in cell ...
Biosynthesis of alkyl-ether containing lipid from dihydroxyacetone phosphate
(Elsevier, 1969-10-22)
A lipid, stable to alkaline methanolysis, is formed when liver mitochondria or brain microsomes are incubated with dihydroxyacetone phosphate, long chain alcohol, ATP, CoA, NaF and Mg++. The lipid has been identified as ...
The ontogeny and distribution of countershading in colonies of the naked mole-rat ( Heterocephalus glaber )
(Blackwell Publishing Ltd, 2001-03)
Most naked mole-rats Heterocephalus glaber are countershaded, with purple-grey dorsal but pale pink ventral skin. The exceptions to this coloration pattern are uniformly pink, and include newborn pups, most queens and ...
Experimental and mathematical modeling studies of protozoan predation on bacteria
(Wiley Subscription Services, Inc., A Wiley Company, 1973-07)
The predation of bacteria by protozoan in both continuous and batch cultures was studied using experimental and modeling techniques. The predator organism was the ciliate, Tetrahymena pyriformis. The bacterium, Aerobacter ...
Comments on rarity and chaos, Thomas D. Rogers, math. biosci. 72:13-18 (1984)
(Elsevier, 1985-03)
On performing experimental studies on transient states of continuous-flow methanogenic reactors
(Wiley Subscription Services, Inc., A Wiley Company, 1990-03-25)
One approach to exploring the behavior of microbial cultures during transient conditions of unbalanced growth is to experimentally observe continuous-flow biological reactors which have been subjected to perturbations in ...
Stimulation of fibroblast proliferation by thrombospondin
(Elsevier, 1989-08-30)
Thrombospondin purified from human platelets was examined for its ability to promote proliferation of human dermal fibroblasts. The results show that thrombospondin could stimulate the incorporation of [3H]thymidine by ...
FORMATION OF RESTING SPORES BY LEPTOCYLINDRUS DANICUS (BACILLARIOPHYCEAE) IN A CONTROLLED EXPERIMENTAL ECOSYSTEM 1
(Blackwell Publishing Ltd, 1980-06)
Leptocylindrus danicus Cleve became the dominant phytoplankton species, comprising 70–80% of the total assemblage, in one of the CEPEX Controlled Experimental Ecosystems (CEE) at Saanich Inlet, British Columbia (Canada). ...
