Endothelin-dependent vasoconstriction in human uterine artery: application to preeclampsia. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: Reduced uteroplacental perfusion, the initiating event in preeclampsia, is associated with enhanced endothelin-1 (ET-1) production which feeds the vasoconstriction of uterine artery. Whether the treatments of preeclampsia were effective on ET-

The mechanism of labor in nonhuman primates: A look inside

open access: yesThe Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Blood vessel assessment using computed tomography : Effects of ephedrine on uterine artery

open access: yesFrontiers in Pharmacology, 2022
Background: Ephedrine increased blood pressure due to the contractile properties of resistance vessels. Excessive contraction of the uterine arteries might cause fetal distress. This study was to determine the diameter of the uterine artery of female New

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

The Effect of Vitamin D3 Supplementation on Increases of Levator Ani Contraction Strength in Women with Uterine Prolapse

open access: yesIndonesian Journal of Obstetrics and Gynecology, 2020
Objective: To investigate the differences of levator muscle contraction strength after vitamin D3 supplementation, thus it is expected that the administration of vitamin D3 can reduce the incidence of uterine prolapse recurrence after reconstructive ...

Personalized Gamified Learning in a Course on the Urogenital System Anatomy: Differential Effects Across Learning Preference Profiles

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Personalized learning approaches adapted to individual metacognitive characteristics have demonstrated promise in Anatomy education. However, whether such benefits are uniform across learner profiles or vary systematically remains an open question with implications for individualized instructional approaches.

The β integrin modulates serotonin sensitivity via NPxY motifs to regulate egg laying and mechanosensation behaviors in Caenorhabditis elegans

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Integrin is an αβ heterodimeric receptor to the extracellular matrix; its binding to the matrix recruits focal adhesions to two NPxY motifs, the tyrosine phosphorylation sites in the cytoplasmic domain. Studies found that replacing tyrosines (Y) with phenylalanines (F) in the motif of β1 integrin displayed little developmental or ...

An electrooptical muscle contraction sensor [PDF]

open access: yes, 2010
An electrooptical sensor for the detection of muscle contraction is described. Infrared light is injected into the muscle, the backscattering is observed, and the contraction is detected by measuring the change, that occurs during muscle contraction ...
