Background: Periodontitis is a chronic, infectious, insidious disease of the tooth-supporting structures that causes a general inflammatory response. The aims of this study were to determine whether periodontitis is associated with endothelial dysfunction leading to cardiovascular events and whether proper management of periodontal disease would improve endothelial function and prevent cardiovascular events in the future.
Methods: Twenty-two patients (12 women, 10 men; 40+/-5 years old) took part in the study. All had severe periodontitis (without systemic disorders) and were all treated conservatively. Thirteen patients returned for a second visit after 3 months of treatment. Endothelial function and periodontal status were evaluated on entry into the study and 3 months following treatment. Ten age-matched, healthy volunteers without periodontal disease served as the control group.
Results: There was a significant difference between the patient group and the healthy controls: FMD% 4.12+/-3.96 vs. 16.60+/-7.86% (p=0.0000). Periodontitis improved significantly in all 13 patients who completed 3 months of treatment, and their endothelial function improved as well: FMD% 4.12+/-3.96% vs. 11.12+/-7.22% (p=0.007). No difference was found in FID% before and after 3 months of treatment: 20.97+/-10.66% vs.17.94+/-6.23% (p=NS).
Conclusions: Periodontitis may be an insidious cause of endothelial dysfunction and cardiovascular events. Treating periodontitis can improve endothelial function and be an important preventive tool for cardiovascular disease.

Background: HIV induced endothelial dysfunction (ED) contributes to cardiovascular disease (CVD) in women with HIV (WWH). Although psychosocial stress has been implicated in the development of CVD in HIV, its impact on ED in WWH remains unknown.
Objectives: The authors hypothesized that posttraumatic stress disorder (PTSD) and HIV interact to contribute to ED in WWH.

Introduction: Hemodynamic forces play a crucial role in modulating endothelial cell (EC) behavior, significantly influencing blood vessel responses. While traditional in vitro studies often explore ECs under static conditions, ECs are exposed to various hemodynamic forces in vivo. This study investigates how wall shear stress (WSS) influences EC metabolism, focusing on the interplay between WSS and key metabolic pathways.

Cardiovascular illnesses are multifactorial disorders and represent the primary reasons for death worldwide, according to the World Health Organization. As a signaling molecule, nitric oxide (NO) is extremely permeable across cellular membranes owing to its unique molecular features, like its small molecular size, lipophilicity, and free radical properties. Some of the biological effects of NO are vasodilation, inhibition in the growth of vascular smooth muscle cells, and functional regulation of cardiac cells.

Purpose: The purpose of this study is to investigate the role of Secretogranin III (Scg3) in the pathogenesis of intraocular neovascular diseases and assess its potential as a therapeutic target for novel treatment strategies.
Methods: A literature review was conducted to examine the expression of Scg3 in intraocular neovascular diseases. We reviewed studies on the interaction of Scg3 with its homologous receptors and its effect on endothelial cell proliferation, migration, and vascular permeability-key processes involved in angiogenesis and neovascularization.

Drosophila and Nanoscience Research Laboratory, Department of Applied Genetics, Karnatak University, Dharwad, Karnataka, 580003, India.
This review explores the intricate connections between Drosophila models and the human blood-brain barrier (BBB) with nanoparticle-based approaches for neurological treatment. Drosophila serves as a powerful model organism due to its evolutionary conservation of key biological processes, particularly in the context of the BBB, which is formed by glial cells that share structural and functional similarities with mammalian endothelial cells. Recent advancements in nanoparticle technology have highlighted their potential for effective drug delivery across the BBB, utilizing mechanisms such as passive diffusion, receptor-mediated transcytosis, and carrier-mediated transport.
