Origins of the avian neural crest: the role of neural plate-epidermal interactions [PDF]
We have investigated the lineage and tissue interactions that result in avian neural crest cell formation from the ectoderm. Presumptive neural plate was grafted adjacent to non-neural ectoderm in whole embryo culture to examine the role of tissue ...

Abstract Background Midline establishment is a fundamental process during early embryogenesis for Bilaterians. Midline morphogenesis in non‐amniotes can occur without mitosis, through Planar Cell Polarity (PCP) signaling. By contrast, amniotes utilize both cellular processes for developing the early midline landmark, the primitive streak (PS).

Abstract Background Previous experiments inducing leakage of embryonic cerebrospinal fluid (CSF) suggest the necessity of intraventricular CSF pressure (PCSF) for brain morphogenesis. Nevertheless, how embryonic PCSF occurs is unclear, especially in utero. Results Using a Landis water manometer, we measured PCSF in fetal mice isolated from the amniotic

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...

Vital dye labelling demonstrates a sacral neural crest contribution to the enteric nervous system of chick and mouse embryos [PDF]
We have used the vital dye, DiI, to analyze the contribution of sacral neural crest cells to the enteric nervous system in chick and mouse embryos. In order to label premigratory sacral neural crest cells selectively, DiI was injected into the lumen of ...

Metal‐Free Perovskites for X‐Ray Detection and Imaging: Progress and Prospects
The MFPs possess structural diversity and photoelectric properties and show attractive advantages for X‐ray detection and imaging. This review highlights the significant roles of components in influencing the material properties and physical parameters of MFPs, and systematically summarizes the advanced progress on both rigid and flexible‐based X‐ray ...
