Stochastic resonance of ELF-EMF in voltage-gated channels: the case of the cardiac I_Ks potassium channel [PDF]
arXiv, 2009 We applied a periodic magnetic field of frequency 16 Hz and amplitude 16 nT to a human I_Ks channel, expressed in a Xenopus oocyte and varied the membrane depolarization between -100 mV and +100 mV. We observed a maximal increase of about 9% in the potassium current at membrane depolarization between 0 mV and 8 mV (see Figure 3).

Expression profile and gap-junctional transfer of microRNAs in the bovine cumulus-oocyte complex
Frontiers in Cell and Developmental BiologyMicroRNAs (miRNA) are important regulators of oocyte maturation, playing a key role in modulating gene expression both in a temporal- and spatial-specific manner.

Geometric Effects in Large Scale Intracellular Flows [PDF]
arXivThis work probes the role of cell geometry in orienting self-organized fluid flows in the late stage Drosophila oocyte. Recent theoretical work has shown that a model, which relies only on hydrodynamic interactions of flexible, cortically anchored microtubules (MTs) and the mechanical loads from molecular motors moving upon them, is sufficient to ...

Photoactivation of neurons by laser-generated local heating [PDF]
arXiv, 2012 We present a method for achieving temporally and spatially precise photoactivation of neurons without the need for genetic expression of photosensitive proteins. Our method depends upon conduction of thermal energy via absorption by a dye or carbon particles and does not require the presence of voltage-gated channels to create transmembrane currents ...

Optical matrix imaging applied to embryology [PDF]
arXivHigh-resolution label-free imaging of oocytes and embryos is essential for in vitro fertilization procedures. Yet conventional microscopy fails in this task because of aberrations and multiple scattering induced by refractive index heterogeneities inside the sample.
