Vascular Endothelial Growth Factor (VEGF) Family and the Immune System: Activators or Inhibitors?

The vascular endothelial growth factor (VEGF) family includes key mediators of vasculogenesis and angiogenesis. VEGFs are secreted by various cells of epithelial and mesenchymal origin and by some immune cells in response to physiological and pathological stimuli. In addition, immune cells express VEGF receptors and/or co-receptors and can respond to VEGFs in an autocrine or paracrine manner.

IMPLEMENTATION OF THE EDUCATIONAL MODULE «MANAGING EXPOSURE ASSESSMENT AND MEDICAL RESPONSE TO A RADIATION EMERGENCY IN UKRAINE».

The WHO educational module УДК «Ma naging exposure assessment and medical response to a radiation emergency in Ukraine» was developed and implemented. In total, 25 trainings were conducted for 377 healthcare professionals from 6 regions of Ukraine during 2023-2024.

Thirteen year experience of vitrectomy and air tamponade for primary retinal detachment repair with clinical outcomes.

Purpose: To report outcomes of pars plana vitrectomy (PPV) with air tamponade for primary rhegmatogenous retinal detachment (RRD) and investigate the impact of vitreous cortex remnants (VCR) on surgical outcomes.

Methods: A retrospective review of 900 patients treated for uncomplicated primary RRD between 2007 and 2020. Exclusion criteria included axial length > 26 mm, prior retinal surgery, giant retinal tear, PVR grade > B, and inadequate follow-up.

The healing process of diabetic ulcers correlates with changes in the cutaneous microbiota.

Skin microbiota plays an essential role in the development and function of the cutaneous immune system, in the maintenance of the skin barrier through the release of antimicrobial peptides, and in the metabolism of some natural products. With the aim of characterizing changes in the cutaneous microbiota specifically associated with wound healing in the diabetic condition, we performed a 16 S rRNA gene Next Generation Sequencing of skin swabs taken within the ulcer bed of ten diabetic patients before (t0) and after 20 days of therapy (t20) with a fluorescein-based galenic treatment. Considering the twenty most representative genera, we found at t20 an increase of Corynebacterium, Peptostreptococcus, and Streptococcus, and a decrease of Enterococcus, Finegoldia, and Peptoniphilus genera.

European croplands under climate change: Carbon input changes required to increase projected soil organic carbon stocks.

Increasing soil organic carbon (SOC) stocks in agricultural systems is a pivotal strategy for promoting soil health and mitigating climate change. Global initiatives have set ambitious targets, aspiring to achieve an annual SOC stock increase of 4 ‰. In the European Union, the recently approved Nature Restoration Law aims to increase SOC stock trends in the top 30 cm of cropland mineral soils.
