Intracellular and extracellular potentials were simultaneously recorded from the soma and different parts of the axon of the giant cell of Aplysia. Evidence was obtained that for all modes of stimulation the spike originates in the axon at some distance from the cell body. The conduction of the spike is blocked at a distance of 200 to 300 micro from the soma for the antidromic spike, closer to ...

Our results suggest that the prominent spike, commonly recorded in wide field amacrine cells, is actively propagated along its processes. Current was passed through a patch pipette at the soma to elicit spike activity in the cell. The field potentials accompanying this spike activity were then measured with an extracellular electrode positioned at different sites along the cell and its processe...

Context. Carbonaceous chondrites are sources of information on the origin Solar System. Their organic content is conventionally classified as soluble (SOM) and insoluble matter (IOM), where latter represents majority. Aims. In this work, our objectives to identify possible relations between generated in laboratory experiments extrapolate analog findings meteorites test their connection. Methods...

A commentary on Past, present, and future of epigenetics applied to livestock breeding The article by González-Recio et al. (2015) claims to " review the concept of Lamarckian inheritance and the use of the term epigenetics in the field of animal genetics. " I began reading with interest as I am involved in selective livestock improvement (Williamson et al., 2011) using the ancestral haplotype ...

Automated and accurate localization and morphometry of somas in 3D neuron images is essential for quantitative studies of neural networks in the brain. However, previous methods are limited in obtaining the location and surface morphology of somas with variable size and uneven staining in large-scale 3D neuron images. In this work, we proposed a method for automated soma locating in large-scale...

Interactions between the soma and germline are essential for gametogenesis. In the Drosophila testis, differentiating germ cells are encapsulated by two somatic cells that surround the germline throughout spermatogenesis. chickadee (chic), the fly ortholog of Profilin, mediates soma-germline interactions. Knockdown of Chic in the soma results in sterility and severely disrupted spermatogenesis ...

The establishment of sexual identity is a crucial step of germ cell development in sexually reproducing organisms. Sex determination in the germline is controlled differently than in the soma, and often depends on communication from the soma. To investigate how sexual identity is established in the Drosophila germline, we first conducted a molecular screen for genes expressed in a sex-specific ...

The transcription factor Flo8/Som1 controls filamentous growth in Saccharomyces cerevisiae and virulence in the plant pathogen Magnaporthe oryzae. Flo8/Som1 includes a characteristic N-terminal LUG/LUH-Flo8-single-stranded DNA binding (LUFS) domain and is activated by the cAMP dependent protein kinase A signaling pathway. Heterologous SomA from Aspergillus fumigatus rescued in yeast flo8 mutant...
