Description of early life history stages of the northern sculpin (Icelinus borealis Gilbert) (Teleostei: Cottidae) [PDF]

open access: yes, 2009
Larvae of the genus Icelinus are collected more frequently than any other sculpin larvae in ichthyoplankton surveys in the Gulf of Alaska and Bering Sea, and larvae of the northern sculpin (Icelinus borealis) are commonly found in the ichthyofauna in ...

A pathway of signals regulating effector and initiator caspases in the developing Drosophila eye [PDF]

open access: yes, 2002
Regulated cell death and survival play important roles in neural development. Extracellular signals are presumed to regulate seven apparent caspases to determine the final structure of the nervous system.

Single-channel recordings from cultured human retinal pigment epithelial cells. [PDF]

open access: yes, 1988
We have applied patch-clamp techniques to on-cell and excised-membrane patches from human retinal pigment epithelial cells in tissue culture. Single-channel currents from at least four ion channel types were observed: three or more potassium-selective ...

The pugilistDominant Mutation of Drosophila melanogaster: A Simple-Sequence Repeat Disorder Reveals Localized Transport in the Eye.

open access: yesPLoS ONE, 2016
The pugilist-Dominant mutation results from fusion of a portion of the gene encoding the tri-functional Methylene Tetrahydrofolate Dehydrogenase (E.C.1.5.1.5, E.C.3.5.4.9, E.C.6.3.4.3) to approximately one kb of a heterochromatic satellite repeat ...

Effects of age, density, and seasonality on molt pattern in the mammal genus (Peromyscus) [PDF]

open access: yes, 2015
Molting, or replacement of pelage (hair) in mammals, occurs during ontogeny as individuals transition from juveniles to adults. Environmental factors can cause variation in molt in many species for thermoregulatory and camouflage purposes.

Vital dye labelling of Xenopus laevis trunk neural crest reveals multipotency and novel pathways of migration [PDF]

open access: yes, 1993
Although the Xenopus embryo has served as an important model system for both molecular and cellular studies of vertebrate development, comparatively little is known about its neural crest.

A vital dye analysis of the timing and pathways of avian trunk neural crest cell migration [PDF]

open access: yes, 1989
To permit a more detailed analysis of neural crest cell migratory pathways in the chick embryo, neural crest cells were labelled with a nondeleterious membrane intercalating vital dye, DiI.
