AI Article Synopsis

  • Gelatin hydrogel nonwoven fabrics, known as Genocel, are being studied for their potential to improve wound healing in diabetic mice, specifically for difficult-to-treat wounds like diabetic foot ulcers, by enhancing blood vessel formation.
  • In the study, both Genocel and a standard skin substitute (Pelnac) were tested on skin defects, and their healing effects were assessed through various histological analyses.
  • Results showed that Genocel had comparable wound healing effects to Pelnac, with the main difference being a lower number of M2 macrophages in the Genocel-treated wounds on day 7, suggesting both materials could be effective in managing diabetic ulcers.

Article Abstract

Background: Gelatin hydrogel nonwoven fabrics (Genocel) are three-dimensional gelatin scaffolds that provide cells with space for proliferation, migration, and differentiation. They are expected to be an effective wound healing modality to treat intractable wounds, such as diabetic foot ulcers, because they enhance early neovascularization when used as a skin substitute. In this study, we explored the healing process of Genocel applied to skin defects in diabetic mice and compared it with that of a conventional skin substitute, Pelnac.

Methods: Genocel and Pelnac sheets were used to treat skin defects on the backs of diabetic mice. On days 7 and 14, the remaining wound area was evaluated and specimens were harvested for HE, Azan, anti-CD31, CD68, and CD163 staining to assess neoepithelialization, granulation tissue formation, capillary formation, and macrophage infiltration.

Results: Wounds treated with Genocel showed a wound healing process comparable to that of wounds treated with Pelnac. No significant differences were observed in the remaining wound area, neoepithelial length, granulation formation, number of pan-macrophages, or M2 ratio on days 7 and 14. The only significant difference was the number of induced M2 macrophages, which was higher in Pelnac group than in the Genocel group on day 7 (p < 0.05).

Conclusions: Genocel showed similar healing effects in diabetic wounds as Pelnac and is considered an effective wound management modality for diabetic ulcers.

Electronic skin is widely employed in multiple applications such as health monitoring, robot tactile perception, and bionic prosthetics. In this study, we fabricated millimeter-scale electronic skin featuring compact sensing units using the Boston Micro Fabrication S130 (a high-precision additive manufacturing device) and the template removal method. We used a gallium-based liquid metal and achieved an inner channel diameter of 0.

Background: Skin cancer is the most common cancer worldwide, with melanoma being the deadliest type, though it accounts for less than 5% of cases. Traditional skin cancer detection methods are effective but are often costly and time-consuming. Recent advances in artificial intelligence have improved skin cancer diagnosis by helping dermatologists identify suspicious lesions.

: Melanoma, an aggressive form of skin cancer, accounts for a significant proportion of skin-cancer-related deaths worldwide. Early and accurate differentiation between melanoma and benign melanocytic nevi is critical for improving survival rates but remains challenging because of diagnostic variability. Convolutional neural networks (CNNs) have shown promise in automating melanoma detection with accuracy comparable to expert dermatologists.

Collective migration of cancer cells is often interpreted using concepts derived from the physics of active matter, but the experimental evidence is mostly restricted to observations made in vitro. Here, we study collective invasion of metastatic cancer cells injected into the mouse deep dermis using intravital multiphoton microscopy combined with a skin window technique and three-dimensional quantitative image analysis. We observe a multicellular but low-cohesive migration mode characterized by rotational patterns which self-organize into antiparallel persistent tracks with orientational nematic order.

Purpose: To describe a technique using retroauricular scalp graft for eyebrow reconstruction, along with problems encountered and countermeasures in treatment.

Methods: We present a patient with eyebrow loss following resection of a malignant schwannoma. We initially covered the defect from the upper eyelid to the eyebrow area with artificial dermis for hemostasis and to increase the granulation of the graft bed.
