Introduction: People with haemophilia (PwH) suffer from haemophilic arthropathy which is accompanied by acute and chronic inflammation. The aim of this study was to examine the neuroinflammatory network operative in PwH and to compare it to healthy controls.
Material And Methods: Blood samples were collected from 41 PwH (age 54.
The aim of the research work was to present a multilayer hydrogel capsule with controlled nutrient release properties as an innovative fertilizer designed for sustainable agriculture. Preparation of the capsules included the following steps: sorption of micronutrients (Cu, Mn, Zn) on eggshells (1) and their immobilization in sodium alginate, with the crosslinking agent being the NPK solution (2). The capsules were coated with an additional layer of a mixture of biopolymers (0.

One of the valorization methods of tannery wastes is the production of biochar by pyrolysis of leather scratches. Biochar's sorption properties and its high nitrogen content (10%) make it suitable for its application as a soil conditioner or carrier of microelements for fertilizers.

- Developed micro-sized hierarchical structures on PLLA surfaces to enhance cell adhesion and growth, using laser modification techniques.
- The structures feature round protrusions with specific dimensions, designed to increase surface roughness and promote non-cytotoxic interactions with cells.
- Experimental results showed that the laser-modified surfaces encouraged better adhesion of human fibroblasts and osteoblasts, while pathogenic bacteria adhered more uniformly, indicating potential for smart implants in regenerative medicine.
In the era of the coronavirus pandemic, one of the most demanding areas was the supply of healthcare systems in essential Personal Protection Equipment (PPE), including face-shields and hands-free door openers. This need, impossible to fill by traditional manufacturing methods, was met by implementing of such emerging technologies as additive manufacturing (AM/3D printing). In this article, Poly(lactic acid) (PLA) filaments for Fused filament fabrication (FFF) technology in the context of the antibacterial properties of finished products were analyzed.
