Hypertrophic scars and keloids are two different manifestations of excessive dermal fibrosis and are caused by an alteration in the normal wound-healing process. Treatment with radiofrequency (RF)-based therapies has proven to be useful in reducing hypertrophic scars. In this study, the effect of one of these radiofrequency therapies, Capacitive Resistive Electrical Transfer Therapy (CRET) on biomarkers of skin fibrosis was investigated. For this, in cultures of human myofibroblasts treated with CRET therapy or sham-treated, proliferation (XTT Assay), apoptosis (TUNEL Assay), and cell migration (Wound Closure Assay) were analyzed. Furthermore, in these cultures the expression and/or localization of extracellular matrix proteins such as α-SMA, Col I, Col III (immunofluorescence), metalloproteinases MMP1 and MMP9, MAP kinase ERK1/2, and the transcription factor NFκB were also investigated (immunoblot). The results have revealed that CRET decreases the expression of extracellular matrix proteins, modifies the expression of the metalloproteinase MMP9, and reduces the activation of NFκB with respect to controls, suggesting that this therapy could be useful for the treatment of fibrotic pathologies.

Breast cancer (BC) is a prevalent malignancy in women, often necessitating tumor resection and breast reconstruction surgeries. However, the post-operation scars can be of concern, as hypertrophic scars (HS) can profoundly impact patients' quality of life. Our study used the bidirectional Mendelian randomization (MR) method to explore the potential relationship between BC and HS.

Bacterial colonisation in hypertrophic scars (HSs) has been reported, yet the precise mechanism of their contribution to scar formation remains elusive. To address this, we examined HS and normal skin (NS) tissues through Gram staining and immunofluorescence. We co-cultured fibroblasts with heat-inactivated Staphylococcus aureus (S.

Hypertrophic scar (HS) is a disease with excessive skin fibrosis and collagen disorder, which is generally caused by abnormal wound repair process after burn and trauma. Although intralesional injection of 5-fluorouracil (5-Fu) has been used in clinical treatment of HS, the patients' compliance of injection treatment is poor. In this study, a double-layer dissolution microneedle (MN) containing asiaticoside (AS) and 5-Fu was designed for the treatment of HS.

Introduction And Hypothesis: The relationship between cesarean section scars and active pelvic floor muscle tone lacks sufficient evidence. This study is aimed at investigating the relationship between the severity of cesarean section scars and active pelvic floor muscle tone in postpartum women.
Methods: We conducted a prospective cross-sectional study of 604 women at 6-8 weeks postpartum.

Background: Treatment of hypertrophic burn scars is challenging. Intralesional injection of corticosteroids has been the first line of treatment. Triamcinolone Acetonide (TA) and Bleomycin (BLE) are standard therapeutic options.
