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.

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.

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.

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.

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.

Exosomes: Generation, structure, transport, biological activity, and diagnostic application
Biochemistry (Moscow) Supplement Series A: Membrane and Cell Biology, 2016Cells of almost all tissues secrete to the extracellular environment a variety of vesicular structures. The most interesting vesicles are exosomes–microvesicles ranging from 30 to 100 nm in size. These vesicles contain various RNA, including mRNA, microRNA, as well as membrane and cytoplasmic proteins that can be transported in these particles to ...

Optimal control of active transport across a biological membrane
Artificial Life and Robotics, 1998We propose an optimal control principle for active transport across a biological membrane. The modeling of the membrane is based on Hill and Kedem's thermodynamic model. The performance function used to evaluate the optimality of the transport involved the rate of time-dependent changes in the concentration of particles in all the membrane layers as ...
