An analysis of contractile and protrusive cell behaviors at the superficial surface of the zebrafish neural plate

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The forces underlying convergence and internalization of the teleost neural plate remain unknown. To help understand this morphogenesis, we analyzed collective and individual cell behaviors at the superficial surface of the neural plate as internalization begins to form the neural keel in the hindbrain region of the zebrafish embryo.

Salivary response and introversion- extraversion

open access: yesActa Psychologica, 1969
Abstract Eysenck has reported a strong correlation between introversion-extraversion and salivary response to fresh lemon juice. In two experiments described here this correlation was not significant. The first experiment consisted of translating and validating the EPI in Dutch, and testing the salivary response to lemon juice.

Pre‐oviposition development of the brown anole (Anolis sagrei)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...

Development of node architecture and emergence of molecular organizer characteristics in the pig embryo

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The avian node is the equivalent of the amphibian Spemann's organizer, as indicated by its ability to induce a secondary axis, cellular contribution, and gene expression, whereas the node of the mouse, which displays limited inductive capacities, was suggested to be a part of spatially distributed signaling.

A novel transgenic reporter of extracellular acidification in zebrafish elucidates skeletal muscle T‐tubule pH regulation

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Disruption of extracellular pH and proton‐sensing can profoundly impact cellular and protein functions, leading to developmental defects. To visualize changes in extracellular pH in the developing embryo, we generated a zebrafish transgenic line that ubiquitously expresses the ratiometric pH‐sensitive fluorescent protein pHluorin2, tethered to

Personality and phobias in adolescence: age and gender in psychopathological expressions [PDF]

open access: yes, 2019
Background: Although the understanding of adolescent phobias is important, this phenomenon has thus far not been adequately researched. This report, based on clinical experience, highlights prevalent phobic phenomena linked to personality characteristics.
