Correction: Baumann et al. Moldavian Dragonhead Extract: A Natural Collagen-Booster to Target Skin Aging. OBM Geriatrics 2025; 9: 305

Julia Baumann, Eva Bönzli, Franziska Wandrey, Torsten Grothe

The complex process of skin aging results in noticeable changes, including decreased collagen content, reduced elasticity, and decreased hydration. Interventions to preserve or restore collagen, a key structural protein, may help counteract these signs. The concept of "beauty from within” through nutritional …

Nutritional supplementation of an apple callus extract to target epidermal aging

Julia Baumann, Franziska Wandrey, Kathrin Nowak, Torsten Grothe

The global increase in life expectancy has led to a growing elderly population, which places a significant burden on healthcare systems. As a result, there is a growing interest to improve healthspan and promote healthy aging with accessible means, such as nutrition …

A novel Ca2+ double cone vector system to treat compromised skin

Julia Baumann, Franziska Wandrey, Riikka Sacher, Fred Zülli

Abstract Background Stressed, damaged or very aged skin is predominantly characterized by a malfunctioning skin barrier. Underlying skin barrier malfunction is a reduced or defective calcium gradient in the epidermis. Consequently, replenishing the compromised skin's calcium stores with topical calcium could be …

Pericyte, but not astrocyte, hypoxia inducible factor-1 (HIF-1) drives hypoxia-induced vascular permeability in vivo

Julia Baumann, Chih-Chieh Tsao, Shalmali Patkar, Sheng‐Fu Huang et autres

BACKGROUND: Ways to prevent disease-induced vascular modifications that accelerate brain damage remain largely elusive. Improved understanding of perivascular cell signalling could provide unparalleled insight as these cells impact vascular stability and functionality of the neurovascular unit as a whole. Identifying key drivers …

Pericyte hypoxia-inducible factor-1 (HIF-1) drives blood-brain barrier disruption and impacts acute ischemic stroke outcome

Chih-Chieh Tsao, Julia Baumann, Sheng‐Fu Huang, Diana Kindler et autres

Pericytes play essential roles in blood-brain barrier integrity and their dysfunction is implicated in neurological disorders such as stroke although the underlying mechanisms remain unknown. Hypoxia-inducible factor-1 (HIF-1), a master regulator of injury responses, has divergent roles in different cells especially during …

Astrocyte-specific hypoxia-inducible factor 1 (HIF-1) does not disrupt the endothelial barrier during hypoxia in vitro

Julia Baumann, Chih-Chieh Tsao, Sheng‐Fu Huang, Max Gassmann et autres

BACKGROUND: Astrocytes (AC) are essential for brain homeostasis. Much data suggests that AC support and protect the vascular endothelium, but increasing evidence indicates that during injury conditions they may lose their supportive role resulting in endothelial cell activation and BBB disturbance. Understanding …

18F-FDG PET Response of Skeletal (Bone Marrow and Bone) Involvement After Induction Chemotherapy in Pediatric Hodgkin Lymphoma: Are Specific Response Criteria Required?

Thomas Georgi, Regine Kluge, Lars Kurch, Lidia Chavdarova et autres

To determine whether the current 18F-FDG PET response criterion for skeletal involvement in Hodgkin lymphoma (HL) is suitable, we performed a systematic evaluation of the different types of skeletal involvement and their response on PET after 2 cycles of chemotherapy (PET-2). A …
