Practitioner Review: Infant mental health meets cell and molecular biology – a look to the future

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background A major research effort in the past two decades has begun to illuminate how experience ‘gets under the skin’ – that is – the cellular and molecular processes that are associated with adversity and resilience. Methods We selectively review three areas of this research: epigenetics, especially DNA methylation, telomere length, and inflammatory

Age and growth of the endemic groovebelly stingray (Dasyatis hypostigma), a heavily exploited batoid in the Brazilian Meridional Margin (21–34° S)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.

The effect of different wavelengths of light during incubation on the development of rhythmic pineal melatonin biosynthesis in chick embryos

open access: yesAnimal, 2019
Rhythmic pineal melatonin biosynthesis develops in chick embryos incubated under a light (L)-dark (D) cycle of polychromatic white light. The spectral sensitivity of the embryonic pineal gland is not known and was investigated in this study.

Structural characterization of newt tendon regeneration after complete transection: In vivo two‐photon imaging and transmission electron microscopy

open access: yesJournal of Anatomy, EarlyView.
The present study characterized newt digital flexor tendon regeneration structurally at both micro‐ and nanoscales following complete transection and suggested that the mechanism of tissue regeneration differs between the early phase (until 6 weeks) and the late phase (after 6 weeks). Tendon stubs remained separated for up to 2 weeks after transection,

Applications of In Ovo Technique for the Optimal Development of the Gastrointestinal Tract and the Potential Influence on the Establishment of its Microbiome in Poultry

open access: yesFrontiers in Veterinary Science, 2016
As the current poultry production system stands, there is a period of time that newly hatched chicks are prevented from access to feed for approximately 48 to 72 hours.

The wide gape of snakes: A comparison of the developing mandibular symphysis in sauropsids

open access: yesJournal of Anatomy, EarlyView.
Our analysis explores the adaptations at the mandibular symphysis required to allow extreme lower jaw mobility in macrostomate snakes taking a comparative approach. Abstract The origin and evolution of snakes has been marked by the acquisition of many morphological and functional novelties, one of which is the possession of a highly kinetic skull ...

Inheritance and Establishment of Gut Microbiota in Chickens

open access: yesFrontiers in Microbiology, 2017
In mammals, the microbiota can be transmitted from the placenta, uterus, and vagina of the mother to the infant. Unlike mammals, development of the avian embryo is a process isolated from the mother and thus in the avian embryo the gut microbial ...

A novel, PCP‐dependent tissue organising principle coordinating morphogenesis between embryonic skin epidermal layers

open access: yesJournal of Anatomy, EarlyView.
‘Outside‐in’ expression of Fz6 across multiple layers of mouse embryo epidermis is connected to Fz6 asymmetry in the basal layer plane. Fz6 loss‐of‐function correlated with failure to: coordinate axial bias of cell long axis orientation across epidermal layers, switch axial cell long axis orientation during suprabasal layer development and establish ...

Evaluation of chicken embryo extract and egg yolk extract as alternatives to basic cell culture medium supplement

open access: yesBMC Research Notes
Background Fetal calf serum (FCS), an existing cell culture supplement, is effective but has several drawbacks, including being expensive, requiring a lengthy process of production, and requiring a hard currency. With this in mind, we planned to evaluate
