Developmental Dynamics, EarlyView.Abstract Neural crest cells are multipotent, migratory stem‐like cells essential for vertebrate development that contribute broadly to many tissues including the craniofacial skeleton, peripheral nervous system, and pigment‐producing cells. Their development progresses through phases of induction, specification, delamination, migration, and ...

Comparative and evolutionary analyses of neurulation in non-teleost fishes [PDF]
, 2018 Neurulation, i. e. formation of a neural tube, is a crucial event in embryogenesis of each vertebrate. This developmental process is rather stereotypical, generally comprising a transformation of a neural plate into a neural tube.

Dynamics of Size and Shape Variation During Embryonic Development in the Balkan Crested Newt
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.Morphological variance in Triturus ivanbureschi embryos fluctuates during the tailbud phase, coinciding with developmental arrest caused by the balanced lethal system. Prehatching embryos show uniform variance. Our study reveals dynamics of morphological variability during early development and provides a baseline for further studies.

NEONATAL DYSFUNCTIONS RESPONSIBLE (EVENTUALLY) FOR DEFINITIVE NEUROLOGICAL HANDICAPS [PDF]
Romanian Journal of Pediatrics, 2009 Beside several malformations, especially cerebral (neurulation disorders, agenesia of the corpus callosum, neuronal migration disorders, etc.), the main neonatal causes of neurological sequelar handicaps are: hipoxya, intracerebral hemorrhage, nuclear ...

MECHANISTIC INSIGHTS INTO SECONDARY NEURULATION
, 2009 The central nervous system is formed by a series of movements referred to as neurulation. There are two modes of neurulation, known as primary and secondary neurulation.

Environmental Toxicology, EarlyView.ABSTRACT Anthropogenic activities and the large volume of compounds released into the environment are sources of contamination for plants, animals, and humans. The herbicide monosodium methyl arsenate (MSMA) ranks among the best‐selling agricultural pesticides in Brazil.

Imaging spectrum of spinal dysraphism: A diagnostic challenge
South African Journal of Radiology, 2023 Spinal dysraphism (SD) is a collective term for congenital malformations of the spine and spinal cord. It includes a wide range of congenital anomalies resulting from aberrations in the stages of gastrulation, primary neurulation and secondary ...

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus
The FEBS Journal, EarlyView.Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not

Dolutegravir induces FOLR1 expression during brain organoid development
Frontiers in Molecular NeuroscienceDuring the first month of pregnancy, the brain and spinal cord are formed through a process called neurulation. However, this process can be altered by low serum levels of folic acid, environmental factors, or genetic predispositions.
