Objective: To evaluate the effect of mixed composite skin graft on the deep partial thickness burn wounds after tangential excision in burn patients.
Methods: Tangential excision was performed in 30 extremities of 23 burn patients within 3 postburn days (PBDs). Then large pieces of homologous acellular dermal matrix were grafted onto the superficial fascia with razor thin autoskin on top of them. The survival rate of skin grafts, the appearance and the functional recovery of the extremities were observed on 10 to 12 post operative day (POD). Skin samples from a healed wound of a patient were harvested three months after the injury for pathologic examination.
Results: The survival rate of the composite skin grafts was 93%. Necrosis was encountered in 7% of the grafts in the lower extremities due to the poor fixation of the grafts leading to separation of autologous skin and the dermal template, and also due to infection resulting in lysis of the grafts. The grafted skin was excellent in the appearance and elasticity, and function of the injured extremities recovered well after grafting after 3 - 6 months of follow-up. Epidermal and dermal texture was also good as shown by pathologic examination.
Conclusion: Mixed composite skin grafting after early tangential excision might be an ideal and effective method in the management of deep partial thickness burn wounds.

This study explores directional selection on physical and psychosocial phenotypes in Eastern Eurasian populations, utilizing a dataset of 1245 ancient genomes. By analyzing polygenic scores (PGS) for traits including height, educational attainment (EA), IQ, autism, schizophrenia, and others, we observed significant temporal trends spanning the Holocene era. The results suggest positive selection for cognitive-related traits such as IQ, EA and autism spectrum disorder (ASD), alongside negative selection for anxiety and depression.

Introduction: Transdermal patches offer a unique advantage by providing extended therapeutic benefits while maintaining stable plasma drug concentration. The efficacy and safety of patches depend significantly on their ability to adhere to the skin, a feature influenced by various external and internal factors.
Areas Covered: The review primarily focuses on the fundamental aspects of adhesion in transdermal patches, including basic information about the skin, the underlying principles of adhesion, drug delivery, and adhesion characteristics of pressure sensitive adhesives (PSAs), adhesion issues, impact factors, strategies to improve patch adhesion, and relevant molecular mechanisms.

Conductive organohydrogel fibers based on sodium alginate (SA) exhibit remarkable flexibility and electrical conductivity, making them ideal candidates for conformal skin adhesion and real-time monitoring of human activity signals. However, traditional conductive hydrogels often suffer from issues such as uneven distribution of conductive fillers, and achieving the integration of high mechanical strength, stretchability, and transparency using environmentally friendly methods remains a significant challenge. In this study, a novel and sustainable strategy was developed to fabricate dual-network organohydrogel fibers using sodium alginate as the primary material.

In this study, the interaction of waste snake skin (Periostracum serpentis), a keratin-based biowaste composite material, with uranyl ions, the predominant form of uranium in aqueous solutions, was investigated to determine whether it could be used as an adsorbent. SEM, FTIR, BET and EDX analyses were performed to elucidate the material's surface and structural properties. The effects of the amount of adsorbent, uranyl ion concentration, pH, temperature, and adsorption time were investigated to optimize uranium removal with this material.
