Objectives: To assess the plasma markers of endothelial dysfunction: VonWillebrand factor (vWF), Platelet derived microparticles (PMPs), and Endothelin-1 (ET-1) in various types of hypertensive disorders of pregnancy and correlate with the pregnancy outcome.
Methods: Plasma levels of vWF, PMPs and ET-1 were analyzed by ELISA kits in gestational hypertension (GH), late onset preeclampsia (LOPE), early onset preeclampsia (EOPE), eclampsia (E) and control pregnant women (CPW) during third trimester. The gestational age at the time of delivery (GA) and birthweight (BW) of the baby also were measured.
Results: The GA and the BW of the baby were found to be significantly lower in EOPE and eclampsia compared to CPW, GH and LOPE. The circulating levels of markers of endothelial dysfunction: vWF, PMPs and ET-1 were significantly higher in EOPE and Eclampsia compared to CPW, GH. Also a negative correlation was observed between vWF levels with pregnancy outcome; GA and BW.
Conclusions: A generalized endothelial dysfunction and poor birth outcomes were observed in hypertensive disorders of pregnancy. There is a spectrum of biochemical derangements related to endothelial dysfunction in GH, EOPE, LOPE and E in that order.

Background: Epidemiological surveys indicate an increasing incidence of type 2 diabetes mellitus (T2DM) among children and adolescents worldwide. Due to rapid disease progression, severe long-term cardiorenal complications, a lack of effective treatment strategies, and substantial socioeconomic burdens, it has become an urgent public health issue that requires management and resolution. Adolescent T2DM differs from adult T2DM.

Idiopathic pulmonary arterial hypertension (iPAH) is a rare, rapidly progressive disease associated with high morbidity and mortality. It is characterized by endothelial dysfunction within the pulmonary vascular bed and gradually leads to an increase in the pulmonary vascular resistances. Its non-specific symptomatology delays the diagnosis and brings the most severe forms to right ventricular failure.

Cellular senescence contributes to inflammation and organ dysfunction during aging. While this process is generally characterized by irreversible cell cycle arrest, its morphological features and functional impacts vary in different cells from various organs. In this study, we examined the expression of multiple senescent markers in the lungs of young and aged humans and mice, as well as in mouse lung endothelial cells cultured with a senescence inducer, suberoylanilide hydroxamic acid (SAHA), or doxorubicin (DOXO).

The appropriate regulation of peripheral vascular tone is crucial for maintaining tissue perfusion. Myoendothelial junctions (MEJs), specialized connections between endothelial cells and vascular smooth muscle cells, are primarily located in peripheral resistance vessels. Therefore, these junctions, with their key membrane proteins, play a pivotal role in the physiological control of relaxation-contraction coupling in resistance arterioles, mainly mediated through endothelium-derived hyperpolarization (EDH).
