Potassium currents distinguish the two subtypes of morphologically distinct skate bipolar cells
(Marine Biological Laboratory, 2004-12)
Bipolar cells in the vertebrate retina are second-order neurons that convey visual information from photoreceptors to ganglion cells, the neurons that relay the message to the brain. Bipolar cells consist typically of ...
Protein methylation in full length Chlamydomonas flagella
Post-translational protein modification occurs extensively in eukaryotic flagella. Here we examine protein methylation, a protein modification that has only recently been reported to occur in flagella (Schneider et al. ...
Cells satisfy the mitotic checkpoint in Taxol, and do so faster in concentrations that stabilize syntelic attachments
(Rockefeller University Press, 2009-08)
To determine why the duration of mitosis (DM) is less in Taxol than in nocodazole or Eg5 inhibitors we studied the relationship between Taxol concentration, the DM, and the mitotic checkpoint. We found that unlike for other ...

Influence of acidic pH on hydrogen and acetate production by an electrosynthetic microbiome
(Public Library of Science, 2014-10-15)
Production of hydrogen and organic compounds by an electrosynthetic microbiome using electrodes and carbon dioxide as sole electron donor and carbon source, respectively, was examined after exposure to acidic pH (~5). ...
Extracellular signal-regulated kinase 1/2 activity is not required in mammalian cells during late G2 for timely entry into or exit from mitosis
(American Society for Cell Biology, 2006-10-11)
Extracellular signal-regulated kinase (ERK)1/2 activity is reported to be required in mammalian cells for timely entry into and exit from mitosis (i.e., the G2-mitosis [G2/M] and metaphase-anaphase [M/A] transitions). ...
Harmonic analysis of the cone flicker ERG of rabbit
(Elsevier B.V., 2010-10-23)
Harmonic analysis was used to characterize the rabbit flicker ERG elicited by sinusoidally modulated full-field stimuli under light-adapted conditions. The frequency-response function for fundamental amplitude, derived ...
CellCognition : time-resolved phenotype annotation in high-throughput live cell imaging
Fluorescence time-lapse imaging has become a powerful tool to investigate complex dynamic processes such as cell division or intracellular trafficking. Automated microscopes generate time-resolved imaging data at high ...
Superfast vocal muscles control song production in songbirds
(Public Library of Science, 2008-07-09)
Birdsong is a widely used model for vocal learning and human speech, which exhibits high temporal and acoustic diversity. Rapid acoustic modulations are thought to arise from the vocal organ, the syrinx, by passive ...
Regeneration of oral siphon pigment organs in the ascidian Ciona intestinalis
Ascidians have powerful capacities for regeneration but the underlying mechanisms are poorly understood. Here we examine oral siphon regeneration in the solitary ascidian Ciona intestinalis. Following amputation, the ...
