Essential role for PDGF signaling in ophthalmic trigeminal placode induction [PDF]

open access: yes, 2008
Much of the peripheral nervous system of the head is derived from ectodermal thickenings, called placodes, that delaminate or invaginate to form cranial ganglia and sense organs.

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...

A 2 year retrospective study of vegan patients and their pregnancy outcomes in a tertiary level Irish hospital

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Recent previous studies have revealed outcomes of higher risk of low birth weight, small for gestational age, and pre‐eclampsia for vegan pregnant women compared to other diets. This review examined if patients with vegan diet in our tertiary hospital had similar outcomes.

In ovo time-lapse analysis of chick hindbrain neural crest cell migration shows cell interactions during migration to the branchial arches [PDF]

open access: yes, 2000
Hindbrain neural crest cells were labeled with DiI and followed in ovo using a new approach for long-term time-lapse confocal microscopy. In ovo imaging allowed us to visualize neural crest cell migration 2-3 times longer than in whole embryo explant ...

Fate mapping identifies the origin of SHF/AHF progenitors in the chick primitive streak [PDF]

open access: yes, 2012
Heart development depends on the spatio-temporally regulated contribution of progenitor cells from the primary, secondary and anterior heart fields. Primary heart field (PHF) cells are first recruited to form a linear heart tube; later, they contribute ...

Exploring the Impact of Polystyrene Microplastic Beads on Male Gonads of the Marine Mussel, Mytilus galloprovincialis

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Plastic, with its remarkable versatility and numerous applications, has greatly benefited humanity. However, its extreme resistance to natural degradation means it persists in the environment for long periods, causing global environmental problems.

Joint interpretation of AER/FGF and ZPA/SHH over time and space underlies hairy2 expression in the chick limb [PDF]

open access: yes, 2012
Embryo development requires precise orchestration of cell proliferation and differentiation in both time and space. A molecular clock operating through gene expression oscillations was first described in the presomitic mesoderm (PSM) underlying periodic ...
