Aim: The present study aims to explore the effects of vitamin E and omega-3 on endothelial function indicators among adolescents with metabolic syndrome.
Method: In a randomized, double blind, and placebo-controlled trial, 90 young individuals, aged 10 to 18 years, with metabolic syndrome were randomly assigned to receive either vitamin E tablets (400 IU/day) or omega-3 tablets (2.4 gr/day) or placebo. For assessing endothelial functional state, the serum level of vascular endothelial growth factor (VEGF) was measured by ELISA test.
Results: The use of omega-3 supplementation for eight weeks led to significant increase in serum HDL level compared with the group treated with vitamin E or placebo group. In this regard, no significant correlations were found between the change in VEGF and baseline levels of other markers including anthropometric indices and serum lipids. Omega-3 could significantly reduce VEGF with the presence of other baseline variables (Beta = -12.55; P = 0.012).
Conclusion: The administration of omega-3 can effectively improve endothelial function in adolescents with metabolic syndrome by reducing the level of serum VEGF, as a major index for atherosclerosis progression and endothelial destabilization. Omega-3 can be proposed as a VEGF antagonist for improving endothelial function in metabolic syndrome. The clinical implications of our findings should be assessed in future studies.

Ovarian function after COVID-19: long-term effects and vaccine safety in ART patients.
J Assist Reprod Genet
January 2025
Ovarian Physiopathology Studies Laboratory, Institute of Experimental Biology and Medicine (IByME) - CONICET, Buenos Aires, Argentina.
Purpose: This study aimed to evaluate the long-term impact of mild COVID-19 infection and COVID-19 vaccination on ovarian function in patients undergoing assisted reproductive technology (ART). Specifically, we assessed ovarian outcomes between 9 and 18 months post-infection and investigated the effects of COVID-19 vaccines (inactivated virus and adenovirus) on reproductive parameters.
Methods: The study included two objectives: (a) examining ovarian function in post-COVID-19 patients (9-18 months post-infection) compared to a control group and (b) comparing reproductive outcomes in vaccinated versus unvaccinated patients.
Differences in Biomarkers of Potential Harm After 2+ Years of Tobacco Heating System Use Compared to Cigarette Smoking: A Cross-Sectional Study.

PMI R&D, Philip Morris Products S.A., Neuchâtel, Switzerland.
Background: Growing evidence indicates that noncombustible products could be a tobacco harm reduction tool for smokers who do not quit. The Tobacco Heating System (THS) emits substantially lower levels of harmful cigarette smoke constituents, and previous randomized clinical studies showed improved levels of biomarkers of potential harm (BoPH) linked to smoking-related disease.
Methods: In this cross-sectional study of healthy participants (n = 982) who (i) smoked cigarettes, (ii) had voluntarily switched from smoking to THS use, or (iii) formerly smoked, blood and urine samples were assayed for nine BoPH.
Effect of Remote Ischemic Conditioning on the Form and Function of Red Blood Cells in Patients With Acute Ischemic Stroke.
Stroke

Department of Neurology, Medical College of Georgia, Augusta University. (M.B.K., B.B., D.C.H.).
Background: Remote ischemic conditioning (RIC) is a simple and low-cost intervention that is thought to increase collateral blood flow through the vasodilatory effects of nitric oxide (NO) produced by the endothelium and red blood cells (RBCs). This study aims to investigate whether RIC affects RBC deformability and levels of NO and nitrite in patients with ischemic stroke.
Methods: This is a predefined substudy to the RESIST (Remote Ischemic Conditioning in Patients With Acute Stroke Trial) randomized clinical trial conducted in Denmark.
XOR-Derived ROS in Tie2-Lineage Cells Including Endothelial Cells Promotes Aortic Aneurysm Progression in Marfan Syndrome.

Background: Marfan syndrome (MFS) is an inherited disorder caused by mutations in the gene encoding fibrillin-1, a matrix component of extracellular microfibrils. The main cause of morbidity and mortality in MFS is thoracic aortic aneurysm and dissection, but the underlying mechanisms remain undetermined.
Methods: To elucidate the role of endothelial XOR (xanthine oxidoreductase)-derived reactive oxygen species in aortic aneurysm progression, we inhibited in vivo function of XOR either by endothelial cell (EC)-specific disruption of the gene or by systemic administration of an XOR inhibitor febuxostat in MFS mice harboring the missense mutation p.
Construction of functional tissue-engineered microvasculatures using circulating fibrocytes as mural cells.

Mural cells are essential for maintaining the proper functions of microvasculatures. However, a key challenge of microvascular tissue engineering is identifying a cellular source for mural cells. We showed that , circulating fibrocytes (CFs) can (1) shear and stabilize the microvasculatures formed by vascular endothelial cells (VECs) in a collagen gel, (2) form gap junctions with VECs and (3) induce basement membrane formation.
