Potential neuroprotective and therapeutic agents and their mechanisms for irradiation‐induced brain injury

Ibrain, EarlyView.
In this review, agents such baicalein, troxerutin, epigallocatechin gallate, quercetin, melatonin, valproic acid, lithium, neurosteroid progesterone, as well as minocycline have been implicated as neuroprotective agents for irradiation‐induced neurological deficits. Also, agents such as glucocorticoids, methylphenidate, vitamin E, bisdemethoxycurcumin,

Hypertensive retinopathy in pre‐eclampsia and its association with disease severity and neonatal outcomes: A retrospective cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Introduction Pre‐eclampsia (PE) involves systemic endothelial dysfunction and microvascular injury, yet routine obstetric care lacks noninvasive readouts of maternal microvascular health. We evaluated whether hypertensive retinopathy (HR) detected during pregnancy is associated with maternal disease severity and adverse neonatal outcomes ...

l-Citrulline dilates rat retinal arterioles via nitric oxide- and prostaglandin-dependent pathways in vivo

Journal of Pharmacological Sciences, 2015
l-Citrulline is an effective precursor of l-arginine produced by the l-citrulline/l-arginine cycle, and it exerts beneficial effects on the cardiovascular system by supporting enhanced nitric oxide (NO) production.

Ginsenoside Rb1 Targets the HRD1‐STING Axis to Mitigate Cholesterol‐Induced VSMC Senescence

Journal of Clinical Laboratory Analysis, EarlyView.
Schematic representation of the proposed mechanism of action for Ginsenoside Rb1. Suppression of HRD1 expression in VSMCs cholesterol stimulation, leading to ER stress (BiP/XBP1s upregulation), STING pathway activation, ROS accumulation (including mitochondrial ROS), and ultimately, VSMC senescence.
