Article Synopsis
- Human placental stem villi (PSV) exhibit contractile properties that were studied through in vitro mechanics in 40 human samples.
- Contractions were triggered using KCl and electrical stimulation, revealing a hyperbolic tension-velocity relationship which allowed for detailed analysis of myosin cross-bridge kinetics.
- Findings indicate that the rate constants for myosin attachment and detachment in human PSV are significantly lower (about 103 times) than those in mammalian striated muscles, with ATPase activity being even slower (by a factor of 105), marking the slowest contractile kinetics observed in mammalian tissues so far.
Background: Hepatitis E Virus (HEV) infection has a poor prognosis among pregnant women from high endemic countries. HEV-prevalence and incidence among pregnant women is unknown in high-income countries such as France. This prospective study was conducted to assess HEV infection in this setting.
