Wound healing: insights into autoimmunity, ageing, and cancer ecosystems through inflammation and IL-6 modulation.

Wound healing represents a complex and evolutionarily conserved process across vertebrates, encompassing a series of life-rescuing events. The healing process runs in three main phases: inflammation, proliferation, and maturation/remodelling. While acute inflammation is indispensable for cleansing the wound, removing infection, and eliminating dead tissue characterised by the prevalence of neutrophils, the proliferation phase is characterised by transition into the inflammatory cell profile, shifting towards the prevalence of macrophages.

A comparative review of coronary computed tomography angiography and myocardial perfusion imaging.

Coronary artery disease remains a leading cause of morbidity and mortality worldwide. Non-invasive imaging techniques have revolutionized the diagnosis and management of coronary artery disease. This review aims to compare the utility and effectiveness of two emerging non-invasive imaging modalities: coronary computed tomography angiography and myocardial perfusion imaging.

Novel approach for biomaterial assessment: utilizing the Ex Ovo quail cam assay for biocompatibility pre-screening.

In recent years, the chorioallantoic membrane (CAM) has emerged as a crucial component of biocompatibility testing for biomaterials designed for regenerative strategies and tissue engineering applications. This study explores angiogenic potential of an innovative acellular and porous biopolymer scaffold, based on polyhydroxybutyrate and chitosan (PHB/CHIT), using the ex ovo quail CAM assay as an alternative to the conventional chick CAM test. On embryonic day 6 (ED6), we placed the tested biomaterials on the CAM alone or soaked them with various substances, including vascular endothelial growth factor (VEGF-A), saline, or the endogenous angiogenesis inhibitor Angiostatin.

Open-Label Interventional Study in Healthy Volunteers to Evaluate NO-Mediated Vasodilation by Dermal Allyl Isothiocyanate Challenge and Whole-Body Heat Stress.

Dermal allyl isothiocyanate (AITC) administration and whole-body heat stress (WBHS) are two challenge models that are used to evaluate physiological mechanisms of vasodilation and pharmacological activity in humans. Their exact vasodilatory mechanisms in humans are not fully elucidated but are likely to be nitric oxide (NO)-mediated. This study aimed to evaluate whether there is overlap in the vasodilatory pathways of dermal AITC application and WBHS by combining the challenges.
