Epidermal electronics with advanced capabilities in near field communications (NFC) are presented. The systems include stretchable coils and thinned NFC chips on thin, low modulus stretchable adhesives, to allow seamless, conformal contact with the skin and simultaneous capabilities for wireless interfaces to any standard, NFC-enabled smartphone, even under extreme deformation and after/during normal daily activities.

Soft conductive gels are essential for epidermal electronics but often face challenges when interfacing with uneven surfaces or areas with extensive hair, especially under mechanical stress. In this study, we employed the concept of liquid-to-solid transformation to enhance integration at biointerfaces and designed an in-situ biogel capable of rapidly transitioning between liquid and solid states within 3 min via a temperature switch. The biogel features a semi-interpenetrating polymer network design and dual conduction pathways, resulting in high tensile strength (~1-3 MPa), a skin-compatible modulus (~0.

Lichen planus (LP) is a chronic inflammatory disease (ISD) affecting skin, mucosa, nail, and hair. Previous studies demonstrated a pivotal role of type 1 immunity in LP, as infiltrating T cells trigger apoptosis and necroptosis in the epidermis. In this study, we investigated the role of DAPK1 in LP with special focus on its role in mediating cell death and inflammation.

Understanding the molecular mechanisms of limb regeneration in decapods can significantly enhance aquaculture production by improving survival and growth, as well as facilitating the development of lab-grown crustacean meat as a sustainable protein source. This review explores the molecular mechanisms of decapod limb regeneration, focusing on the key signaling pathways, genes, and proteins involved in this process. The initial stages of regeneration involve immune response and hemolymph coagulation, which are regulated via signaling pathways such as Toll, MAPK, IMD, and JAK/STAT.

Psoriasis is difficult to treat clinically and lacks an effective treatment. Low-molecular-weight heparin sodium (LMH) is an animal glycosaminoglycan with anti-inflammatory properties. Transdermal and intradermal retention studies have suggested that LMH sodium can reach the dermis.
