ALKBH5-mediated mA demethylation ameliorates extracellular matrix deposition in cutaneous pathological fibrosis.

Background: Elevated extracellular matrix (ECM) accumulation is a major contributing factor to the pathogenesis of fibrotic diseases. Recent studies have indicated that N6-methyladenosine (mA) RNA modification plays a pivotal role in modulating RNA stability and contribute to the initiation of various pathological conditions. Howbeit, the precise mechanism by which mA influences ECM deposition remains unclear.

Immunomodulation of wound healing leading to efferocytosis.

Effectively eliminating apoptotic cells is precisely controlled by a variety of signaling molecules and a phagocytic effect known as efferocytosis. Abnormalities in efferocytosis may bring about the development of chronic conditions, including angiocardiopathy, chronic inflammatory diseases and autoimmune diseases. During wound healing, failure of efferocytosis leads to the collection of apoptosis, the release of necrotic material and chronic wounds that are difficult to heal.

Targeting the nuclear long noncoding transcript LSP1P5 abrogates extracellular matrix deposition by trans-upregulating CEBPA in keloids.

Keloids are characterized by fibroblast hyperproliferation and excessive accumulation of extracellular matrix (ECM) and are a major global health care burden among cutaneous diseases. However, the function of long noncoding RNA (lncRNA)-mediated ECM remodeling during the pathogenesis of keloids is still unclear. Herein, we identified a long noncoding transcript, namely, lymphocyte-specific protein 1 pseudogene 5 (LSP1P5), that modulates ECM component deposition in keloids.

Total Face Reconstruction with Flap Prefabrication and Soft-Tissue Expansion Techniques.

Total facial deformities always lead to psychological and functional consequences, making plastic and reconstructive surgery a great challenge. The skin of the anterior chest area is matched in thickness, texture, and color to the head and face. The purpose of this article was to discuss and evaluate reconstructive surgeons' experiences with obtaining a monoblock flap from the anterior thoracic area for entire face reconstruction using flap prefabrication, soft-tissue expansion, and facial plastic surgery following skin flap transplantation.

Salvaging Complex Lower Extremity Injury with Laparoscopically Harvested Omental Flaps.

Background: Traumatic injuries to the lower extremities are frequently accompanied by extensive soft tissue loss, combined with vascular damage or exposure of bony tissues, making it difficult to reconstruct; consequently, patients are commonly at risk of amputation. Due to its superior anatomical and biochemical properties, the omental flap has been used to reconstruct soft tissue defects for decades. However, few studies have reported the omental flap's effectiveness in treating severe and complex lower extremity deformities.

Smart and versatile biomaterials for cutaneous wound healing.

The global increase of cutaneous wounds imposes huge health and financial burdens on patients and society. Despite improved wound healing outcomes, conventional wound dressings are far from ideal, owing to the complex healing process. Smart wound dressings, which are sensitive to or interact with changes in wound condition or environment, have been proposed as appealing therapeutic platforms to effectively facilitate wound healing.

ALKBH5-mediated mA demethylation fuels cutaneous wound re-epithelialization by enhancing PELI2 mRNA stability.

Background: Impaired wound re-epithelialization contributes to cutaneous barrier reconstruction dysfunction. Recently, N-methyladenosine (mA) RNA modification has been shown to participate in the determination of RNA fate, and its aberration triggers the pathogenesis of numerous diseases. Howbeit, the function of mA in wound re-epithelialization remains enigmatic.

Midface Prelamination by Using a Three-Dimensional Cervicothoracic Prefabricated Flap.

The midface is an important area in aesthetics and function and a complex area to manage after burn injuries, trauma, and tumor resection. Traditional treatment to reconstruct midface defects involving the nose, lips, and cheeks requires multiple sequential flap operations but results in a patch-like appearance, which remains a major challenge for head and neck reconstructive surgeons. This article describes how the authors perform prelamination using the prefabricated cervicothoracic flap on the anterior chest for midface reconstruction.

Extracellular RNA in melanoma: Advances, challenges, and opportunities.

Melanoma, a malignant mass lesion that originates in melanocytes and has a high rate of malignancy, metastasis, and mortality, is defined by these characteristics. Malignant melanoma is a kind of highly malignant tumor that produces melanin and has a high mortality rate. Its incidence accounts for 1%-3% of all malignant tumors and shows an obvious upward trend.
