Journal ArticleDOI
Longitudinal diffusion in retinal rod and cone outer segment cytoplasm: the consequence of cell structure.
David Holcman,Juan I. Korenbrot +1 more
TL;DR: This work developed a new theoretical analysis to explicitly compute the longitudinal diffusion constant, Dl, in terms of outer segment structure and used numerical simulations of the theoretical model to investigate cGMP diffusion in outer segments of various species.
Journal ArticleDOI
Phospholipase A2 activity towards vesicles of DPPC and DMPC–DSPC containing small amounts of SMPC
TL;DR: The results clearly show that the PLA(2) activity is significantly enhanced by lipid bilayer micro-heterogeneity in both one-component and multi-component lipid bilayers substrates.
Journal ArticleDOI
Temporal sampling, resetting, and adaptation orchestrate gradient sensing in sperm
Nachiket D. Kashikar,Luis Alvarez,Reinhard Seifert,Ingo Gregor,Ingo Gregor,Oliver Jäckle,Michael Beyermann,Eberhard Krause,Ulrich Benjamin Kaupp +8 more
TL;DR: Sperm use temporal sampling, resetting of intracellular calcium level, and adaptation of their sensitivity to respond to a wide range of chemoattractant concentrations during their voyage toward the egg.
Journal ArticleDOI
Effects of organic antagonists of Ca2+, Na+, and K+ on chemotaxis and motility of Escherichia coli
TL;DR: Various Ca(2+) antagonists used in animal research inhibited Escherichia coli chemotaxis (measured as entry of cells into a capillary containing attractant); the most effective of these, acting in the nanomolar range, was omega-conotoxin GVIA.
Journal ArticleDOI
Regions of cardiorespiratory synchronization in humans under paced respiration.
TL;DR: Cardiorespiratory synchronization under paced respiration is studied systematically as the respiration frequency is changed between 3 and 30 breaths per min to study the existence of n:m synchronization regions of finite width.
