Three-dimensional cephalometric evaluation of maxillary growth following in utero repair of cleft lip and alveolar-like defects in the mid-gestational sheep model [PDF]

open access: yes, 2006
Objective: To evaluate maxillary growth following in utero repair of surgically created cleft lip and alveolar (CLA)-like defects by means of three-dimensional (3D) computer tomographic (CT) cephalometric analysis in the mid-gestational sheep model ...

Developmental and functional effects of steroid hormones on the neuroendocrine axis and spinal cord [PDF]

open access: yes, 2016
This review highlights the principal effects of steroid hormones at central and peripheral levels in the neuroendocrine axis. The data discussed highlight the principal role of oestrogens and testosterone in hormonal programming in relation to sexual ...

Dielectrophoretic trapping of dissociated fetal cortical rat neurons [PDF]

open access: yes, 2000
Recording and stimulating neuronal activity at multiple sites can be realized with planar microelectrode arrays. Efficient use of such arrays requires each site to be covered by at least one neuron.

Short fetal leukocyte telomere length and preterm prelabor rupture of the membranes. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Rupture of the fetal membranes is a common harbinger of imminent labor and delivery. Telomere shortening is a surrogate for oxidative stress (OS) and senescence.

Truncated human endothelin receptor A produced by alternative splicing and its expression in melanoma [PDF]

open access: yes, 1998
In this study, reverse transcriptase polymerase chain reaction was used to amplify human endothelin receptor A (ETA) and ETB receptor mRNA. A truncated ETA receptor transcript with exons 3 and 4 skipped was found.

Initiation of human parturition: signaling from senescent fetal tissues via extracellular vesicle mediated paracrine mechanism [PDF]

open access: yesObstetrics & Gynecology Science, 2019
A better understanding of the underlying mechanisms by which signals from the fetus initiate human parturition is required. Our recent findings support the core hypothesis that oxidative stress (OS) and cellular senescence of the fetal membranes (amnion ...

The variation in transparency of amniotic membrane used in ocular surface regeneration [PDF]

open access: yes, 2010
Background/aims: Scant consideration has been given to the variation in structure of the human amniotic membrane (AM) at source or to the significance such differences might have on its clinical transparency.

Adhesive and degradative properties of human placental cytotrophoblast cells in vitro. [PDF]

open access: yes, 1989
Human fetal development depends on the embryo rapidly gaining access to the maternal circulation. The trophoblast cells that form the fetal portion of the human placenta have solved this problem by transiently exhibiting certain tumor-like properties ...

Bacteria localization and chorion thinning among preterm premature rupture of membranes. [PDF]

open access: yesPLoS ONE, 2014
OBJECTIVE: Bacterial colonization of the fetal membranes and its role in pathogenesis of membrane rupture is poorly understood. Prior retrospective work revealed chorion layer thinning in preterm premature rupture of membranes (PPROM) subjects.
