Ultrastructural studies of the morphological variations of the egg surface and envelopes of the African catfish Clarias gariepinus (Burchell, 1822) before and after fertilisation with a discussion of fertilisation mechanism

open access: yesScientia Marina, 2006
Much of the existing knowledge of the mechanisms involved in teleost fertilisation is based on a few small model species that have no commercial value. Research is therefore urgently required to address mechanisms involved in fertilisation in species of ...

Yellow-y Functions in Egg Melanization and Chorion Morphology of the Asian Tiger Mosquito, Aedes albopictus

open access: yesFrontiers in Cell and Developmental Biology, 2021
The Asian tiger mosquito, Aedes albopictus, is one of the most serious public health pests, which can transmit various vector-borne diseases. Eggs from this mosquito species become dark black shortly after oviposition and exhibit high desiccation ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Evaluation of the effect of different methods of curacy on women with adenomyosis in the first half of pregnancy on the development of early gestative complications

open access: yesJournal of Education, Health and Sport, 2019
Pregnancy in women with adenomyosis has an increased risk of multiple obstetric complications, especially early pregnancy losses. The purpose of the study was to conduct a comparative analysis of the impact of different methods of curation of pregnant ...

Immunosuppressive property of amnion and chorion MSCs.

open access: yes, 2014
(A) Inhibition of human CD4+ T cell proliferation upon co-culture with human amnion, chorion, and bone marrow MSCs. (B) The concentration of PGE2 in FM-MSC-conditioned medium was measured by ELISA.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

HERNIA OR DIVERTICULUM OF THE CHORION. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1900
Cysts of the placenta have been reported by Millet and others, supposed to have developed from the exudation of blood forming a clot separating the chorion, usually of small size, and in some cases more than one is noted. Ercolani reported two cases; in one the entire fetal surface of the placenta was sown with round tumors covered by chorion—the ...

m6A‐Driven Pexophagy Triggers Placental Ferroptosis to Impair Fetal Growth Upon Environmental Stress

open access: yesAdvanced Science, EarlyView.
Prenatal environmental stress exposure promotes m6A modification to drive PEX2‐dependent pexophagy, thereby causing placental ferroptosis and FGR. ABSTRACT The role and underlying mechanisms of placental ferroptosis in fetal growth restriction (FGR) induced by environmental stress remain poorly understood.
