Transport and biological activities of bile acids
The International Journal of Biochemistry & Cell Biology, 2013Bile acids have emerged as important biological molecules that support the solubilization of various lipids and lipid-soluble compounds in the gut, and the regulation of gene expression and cellular function. Bile acids are synthesized from cholesterol in the liver and eventually released into the small intestine.

Transport of biologically active material in laser cutting
Lasers in Surgery and Medicine, 1988AbstractThe transport of biologically active material during laser cutting with CO2 and Er lasers is demonstrated. This transport mechanism removes particles from the surface of gelatin, agar, and liver samples into the depth of the laser‐formed craters. The transport phenomenon is explained by a contraction and condensation of enclosed hot water vapor.

Activation of sodium transport across biological membranes
Experientia, 1971Es wird die Temperaturabhangigkeit zur Entscheidung uber den «aktiven» oder «passiven» Na-Transport in der Amphibienhaut benutzt: Oxytocin verandert die Na-Permeabilitat, wahrend zyklisches AMP (+Thophyllin) einen aktiven Prozess zu beeinflussen scheint.

Biological Activity of Macrocyclic Cation Transporters
Current Organic Chemistry, 2015This review describes two families of ion transporters: the lariat ethers and the hydraphiles. The lariat ethers transport ions as carriers and hydraphiles of appropriate length form pores in bilayer membranes.

Oligonucleotide biological activity: Relationship to the cell cycle and nuclear transport
Biology of the Cell, 1997Previous studies suggest that oligodeoxynucleotide (ODN) cellular uptake is cell cycle‐dependent which may have important implications in cancer cell targeting. To further our understanding of ODN transport and activity, this study examines the relationships between the cell cycle, ODN cellular uptake, intracellular transport, and activity.

The theory of transport phenomena in biological membranes. II. The active transport of ions
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1970Abstract A model is suggested coupling the processes of the passive and active transport of the Na + and K + in biological membranes. It is shown that the mechanism of active transport has features common to the mechanism of passive transport. However, it differs in the driving force maintaining the directed flow of ions.
