Serratus Anterior Fascia Free Flap for Functional Surgery of Subungual Melanoma: Case Series and Literature Review.

 In addressing subungual melanoma, this study presents the efficacy of wide excision followed by reconstruction using a serratus anterior fascial free flap.  The study covers four patients treated between 2017 and 2020 for melanoma in the great toe or thumb, highlighting the successful application of the flap and split-thickness skin graft over exposed distal phalanx cortical bone.  The Breslow depths of the melanomas ranged from 0.

Association of Right Ventricular-Pulmonary Arterial Coupling and Progression of Tricuspid Regurgitation in Patients With Atrial Fibrillation.

Background: Tricuspid regurgitation (TR) severity is associated with poor prognosis in patients with atrial fibrillation (AF). Recently, right ventricular-pulmonary arterial (RV-PA) coupling has been shown to be related to clinical outcomes in patients with TR. However, data on the relationship of RV-PA coupling to the progression of significant TR are limited.

Therapeutic Potential of Extract for Hair Health Enhancement: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial.

Hair health critically influences both aesthetic appearance and psychological well-being. Existing treatments often show limited efficacy and may cause side effects. (GP), known for its antioxidant and anti-inflammatory properties, has emerged as a promising botanical agent, although clinical evidence regarding its hair health benefits remains limited.

Effect of Heat Treatment on Corrosion Resistance of A356 Casting Alloy.

Al-Si alloy, known for its excellent corrosion resistance and high strength, is utilized across various industries, such as electric vehicles, requiring light metal parts for efficiency. Heat treatment is an effective process for enhancing the performance of Al-Si alloys by controlling the microstructure and precipitation. Optimized heat treatment improves the mechanical properties of Al-Si alloy, including strength, hardness, and corrosion resistance.

Effect of Prolonged Exposure to Beverage on Color Stability and Surface Roughness of Tooth-Colored Restorative Materials.

The purpose of this in vitro study was to compare color stability and surface roughness of different tooth-colored restorative materials commonly used in pediatric dentistry after prolonged immersion into grape juice. Forty disc specimens were prepared using pink opaquer (PO), pink opaquer with composite resin (DUAL), composite resin (COMP), and resin-modified glass ionomer (RMGI) of two-mm thickness. 3D-printed wells were fabricated in CD4 shade.
