Differential sensitivity of midline development to mitosis during and after primitive streak extension

open access: yesDevelopmental Dynamics, EarlyView.
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).

Embryonic cerebrospinal fluid pressure in fetal mice in utero: External factors pressurize the intraventricular space

open access: yesDevelopmental Dynamics, EarlyView.
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

Biophysical processes of morphogenesis in lizard lungs

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Sobrevivência de Salmonella enteritidis em Ovos Contaminados Artificialmente, Após Desinfecção e Armazenados em Diferentes Temperaturas Survival of Salmonella enteritidis in Eggs Artificially Contaminated, After Disinfection and Stored at Different Temperatures

open access: yesBrazilian Journal of Poultry Science, 2001
Avaliou-se a contaminação da casca e do conteúdo interno de ovos inoculados com Salmonella enterica sorovar enteritidis fagotipo 4, lavados com água de torneira (AT) ou solução de amônia quaternária (AQ) e armazenados a 8ºC e 25ºC. Duzentos e cinqüenta e

Galactic archaeology: IMF and depletion in the "thin disk"

open access: yes, 2003
We determine the initial mass function (IMF) of the ``thin disk'' by means of a direct comparison between synthetic stellar samples (for different matching choices of IMF, star formation rate SFR and depletion) and a complete (volume-limited) sample of ...

Replication of Marek's Disease Virus Is Dependent on Synthesis of De Novo Fatty Acid and Prostaglandin E2 [PDF]

open access: yes, 2019
Marek’s disease virus (MDV) causes deadly lymphoma and induces an imbalance of the lipid metabolism in infected chickens. Here, we discovered that MDV activates the fatty acid synthesis (FAS) pathway in primary chicken embryo fibroblasts (CEFs).

Bridging maternal effects and epitranscriptomics: A novel perspective in developmental biology

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Maternal effects, encompassing both genetic (maternally expressed gene products) and non‐genetic (maternal state) influences, are powerful determinants of offspring phenotype, yet their RNA‐level mechanisms remain incompletely resolved. In parallel, epitranscriptomics, an emerging field centered on chemical modifications to RNA, has revealed ...

Ovum in Ovo [PDF]

open access: yesThe American Naturalist, 1899
AN interesting case of egg within egg recently came to hand, which was unique in this respect: that the smaller enclosed egg lay in the yolk and not in the albumen of the surrounding egg, as in all similar instances hitherto recorded.' This hen's egg had unfortunately been cooked.

The Associations Between Vegetarian and Vegan Diets and Orthorexia Nervosa Symptoms in Adults: A Systematic Review and Meta‐Analysis

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective To synthesize the evidence on the associations between vegetarian and/or vegan diets (VVDs) and symptoms of orthorexia nervosa (ON) compared with omnivorous diets in the adult population. Method Following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) and the Meta‐analyses of Observational Studies in ...
