Development of the Entorhinal Cortex Occurs via Parallel Lamination During Neurogenesis.

The entorhinal cortex (EC) is the spatial processing center of the brain and structurally is an interface between the three layered paleocortex and six layered neocortex, known as the periarchicortex. Limited studies indicate peculiarities in the formation of the EC such as early emergence of cells in layers (L) II and late deposition of LIII, as well as divergence in the timing of maturation of cell types in the superficial layers. In this study, we examine developmental events in the entorhinal cortex using an understudied model in neuroanatomy and development, the pig and supplement the research with BrdU labeling in the developing mouse EC.

Risk factors for gastric ulceration in nursery pigs.

Pars oesophageal gastric ulceration is a prevalent condition in swine production and often observed in finisher pigs at slaughter, with reported prevalence ranging from 32 % to 65 %. Although feeding practices in nursery and finisher pigs are similar, little is known about the prevalence and risk factors associated with this condition in nursery pigs. This prospective cohort study aimed to identify risk factors for gastric ulceration in nursery pigs.

Association between gastric content fluidity and pars oesophageal ulcers in nursery pigs: a cross-sectional study of high-risk Danish herds using commercial feed.

Background: The objective of this cross-sectional study was to assess the within-herd prevalence of pars oesophageal ulcers (POU) in high-risk Danish herds using commercial diets. Furthermore, we aimed to estimate the association between gastric content fluidity and POU using a generalised additive model (GAM). The study included 200 clinically healthy nursery pigs randomly selected from ten farms (20 pigs from each farm).

Isolation and culture of porcine primary fetal progenitors and neurons from the developing dorsal telencephalon.

The development of long-term surviving fetal cell cultures from primary cell tissue from the developing brain is important for facilitating studies investigating neural development and for modelling neural disorders and brain congenital defects. The field faces current challenges in co-culturing both progenitors and neurons long-term. Here, we culture for the first time, porcine fetal cells from the dorsal telencephalon at embryonic day (E) 50 and E60 in conditions that promoted both the survival of progenitor cells and young neurons.
