Insulin and myometrial contractility; Are there any links? A narrative review.

Contrary to the evidence supporting the role for insulin in stimulating uterine contraction, only a limited number of studies have highlighted the inhibitory effect of insulin on myometrial contractions in human and rodent. A hypothetical narrative review of the current literature was conducted, revealing the current literature and shows the potential inhibitory effects of insulin on myometrial contractility. These inhibitory mechanisms include activation of adenylyl cyclase signaling pathways, an increase in cAMP production, a decrease in Ca influx and cytosolic Ca, hyperpolarization of the cell membrane, and stimulation of NO synthesis.

The imbalance of circulating pro-inflammatory cytokines interleukin-12 and interferon gamma and anti-inflammatory cytokine interleukin-1ra in chronic insomnia disorder.

A growing body of literature suggests that cytokines can play an important role in chronic insomnia disorder (CID); however, the underlying mechanisms are still unknown. Here we show that serum levels of pro-inflammatory mediators including IL-12, IFN-γ and ICAM-1 are elevated in CID group when compared with healthy controls, and that the REM sleep duration diminishes with increased concentrations of IL-12 and IFN-γ in individuals with CID. Furthermore, we find that lowered serum concentration of IL-1ra is negatively correlated with severity of insomnia in CID group.
