The life expectancy of patients with Tetralogy of Fallot (ToF) has increased in recent years. As a result, other risk factors with later onset in life are in the focus of patient care. Endothelial function is an early indicator of cardiovascular risk and was investigated along further structural vessel properties. A total of 17 patients (41.7 ± 7.1 years, 8 women) with Tetralogy of Fallot were 1:2 matched for sex with 34 (38.9 ± 8.1 years, 16 women) healthy volunteers. Participants received an assessment of their endothelial function and a structural assessment of the aorta. Patients with ToF showed a reduced endothelial function determined by reactive hyperaemia index after adjusting for age, weight and height (ToF: 1.55 ± 0.31 vs. controls: 1.84 ± 0.47; = 0.023). No differences in carotid intima-media thickness (cIMT) between the ToF and healthy controls (ToF: 0.542 ± 0.063 mm vs. controls: 0.521 ± 0.164 mm; = 0.319) were found. Patients with ToF had reduced vascular function compared to healthy subjects. As the structural component is not affected, endothelial dysfunction seems not to have yet manifested itself as a morphological change. Nevertheless, long-term management of these patients should include vascular parameters.

Background: Iduronate-2-sulfatase (IDS) deficiency (MPS II; Hunter syndrome) is a disorder that exhibits peripheral and CNS pathology. The blood brain barrier (BBB) prevents systemic enzyme replacement therapy (ERT) from alleviating CNS pathology. We aimed to enable brain delivery of systemic ERT by using molecular BBB-Trojans targeting endothelial transcytosis receptors.

Indirect bypass using autologous tissue is effective in Moyamoya disease, especially among pediatric patients. This study aimed to evaluate the effectiveness of indirect bypass using DuraGen (absorbable artificial dura mater composed of collagen matrix), as a substitute for autologous tissue in a rat model of chronic cerebral hypoperfusion. Male Wistar rats were subjected to bilateral internal carotid artery occlusion and divided into three groups: a control group without bypass surgery, a group wherein indirect bypass was performed using the temporalis muscle (encephalo-myo-synangiosis [EMS] group), and a group wherein DuraGen was used (Dura group).

Anxiety disorder, a prevalent mental health issue, is one of the leading causes of disability worldwide. Damage to the blood-brain barrier (BBB) is implicated in anxiety, but its regulatory mechanisms remain unclear. Herein, we show that adrenomedullin 2 (ADM2), a novel angiogenic growth factor, alleviates autistic and anxiety-like behaviors in mice.

Background: The process of kidney transplantation remains the optimal treatment for end-stage renal disease, offering improved quality of life and increased survival rates compared to long-term dialysis. However, despite advances in surgical techniques, immunosuppression regimens, and post-operative care, there are still significant challenges in predicting the organ's status and long-term outcomes of transplantation. Among the many factors that influence graft survival, the quality of the donated organ plays a fundamental role.

Chronic non-healing wounds are a common complication of diabetes, marked by impaired angiogenesis. This study explores how exosomes (Exo-miR-1248) from miR-1248-overexpressing adipose-derived stem cells enhance diabetic wound healing by modulating endothelial cell function. Adipose-derived stem cells were transfected with a lentivirus carrying miR-1248 to produce Exo-miR-1248, isolated via differential centrifugation.
