Summary
In normal pregnancy, maternal endothelial function declines with gestational age. This deterioration is inversely correlated with increasing levels of plasma soluble fms-like tyrosine kinase-1 (sFlt-1).
Area of Science:
- Obstetrics and Gynecology
- Cardiovascular Physiology
- Reproductive Medicine
Background:
- Endothelial dysfunction is a hallmark of various pregnancy complications.
- Soluble fms-like tyrosine kinase-1 (sFlt-1) is implicated in endothelial dysfunction.
- Understanding endothelial function changes in normal pregnancy is crucial for identifying pathological states.
Purpose of the Study:
- To investigate the longitudinal changes in maternal endothelial function during normal pregnancy.
- To examine the relationship between endothelial function and plasma levels of soluble fms-like tyrosine kinase-1 (sFlt-1) throughout gestation.
Main Methods:
- Endothelial function was assessed using the reactive hyperemia index (RHI) via Endo-PAT2000.
- Plasma sFlt-1 concentrations were measured concurrently using enzyme-linked immunosorbent assay (ELISA).
Main Results:
- A progressive decline in RHI was observed as gestational age advanced.
- Plasma sFlt-1 levels showed a gradual increase in late pregnancy.
- A significant inverse correlation was found between RHI and plasma sFlt-1 levels.
Conclusions:
- Maternal endothelial function deteriorates progressively with advancing gestational age in normal pregnancy.
- Plasma sFlt-1 levels increase with gestational age and correlate inversely with endothelial function.
- These findings highlight a potential role for sFlt-1 in modulating endothelial function during normal pregnancy.

Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Hormonal Regulation
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.
