Article Synopsis
- The study investigates employee burnout stemming from prolonged workplace stress and aims to develop techniques to address it, specifically using a virtual reality (VR) and biofeedback intervention called ReViSide.
- In a randomized controlled trial with 140 adult participants experiencing emotional burnout, one group will use the ReViSide technology while the control group receives traditional psychocorrection, measuring outcomes like emotional burnout and mental health symptoms.
- The hypothesis is that participants using VR will show more significant improvements in burnout levels, including emotional exhaustion and personal accomplishment, along with potential changes in brain activity linked to lower distress levels.
Hypoxic perfusion of pulmonary arterial vasa vasorum increases pulmonary arterial pressure.

The pathophysiology of pulmonary hypertension (PH) is not fully understood. Here, we tested the hypothesis that hypoxic perfusion of the vasa vasorum of the pulmonary arterial (PA) wall causes PH. Young adult pig lungs were explanted and placed into a modified ex vivo lung perfusion unit (organ care system, OCS) allowing the separate adjustment of parameters for mechanical ventilation, as well as PA perfusion and bronchial arterial (BA) perfusion.

A warning sign for impending cardiovascular events is not fully established. In the process of plaque rupture, the formation of vulnerable plaque is important, and oxidized cholesterols play an important role in its progression. Furthermore, the significance of vasa vasorum penetrating the medial smooth muscle layer and being rich in atheromatous lesions should be noted.
