Background: The zone of stasis that forms in acute burn is initially viable, but coagulation progresses to necrosis in the process that follows.
Objective: This study investigates the effects of platelet-rich plasma (PRP) on apoptosis in the burn zone of stasis and on the viability of living tissue.
Methods: Burns were established in the right ears of 20 female New Zealand rabbits using the "comb burn" model. Platelet-rich plasma was obtained from blood collected from rabbits' ears (n = 10) and was injected subcutaneously into the zone of stasis (n = 10). The same amount of saline solution was injected into the zone of stasis of the control group rabbits (n = 10). Histological and immunohistochemical apoptosis analysis was performed to evaluate viable areas.
Results: Apoptosis levels were higher in the control group than in the experimental group. The area of viable tissue in the zone of stasis was greater than in the control group. Infection-induced neutrophil infiltration was statistically significantly lower in the experimental group.
Conclusion: In this animal model, apoptosis count and viable tissue area measurement and the anti-inflammatory results in the burn area confirm that PRP therapy has a statistically significant positive impact on the survival of the zone of stasis and in acute burn injury.

Article Synopsis
- - Hemorrhage is the main cause of preventable death in trauma situations, leading to military and civilian advancements in medical practices, particularly through the use of tourniquets to manage extremity bleeding and save lives.
- - While tourniquets have significantly decreased deaths from bleeding in military settings, noncompressible hemorrhage still poses a major risk, especially before patients receive definitive medical care.
- - The study explores using a small, disposable pressure monitor during resuscitative endovascular balloon occlusion of the aorta (REBOA) to enhance blood pressure monitoring, facilitate better resuscitation practices, and reduce the need for blood products in extreme environments.
The Influence of Preablation Embolization Particle Size on the Size of the Microwave Ablation Zone in a Porcine Orthotopic Renal Tumor Model.

Article Synopsis
- The study aimed to evaluate the effectiveness of combining arterial embolization with various embolic agents and microwave ablation (MWA) in reducing the size of renal tumor ablation zones in pigs.
- Researchers conducted experiments on 32 tumors, using different embolic materials before applying MWA, and then assessed the changes in ablation zones through gross and histologic analysis.
- Results showed that the use of smaller particle sizes for embolization significantly increased the size of the ablation zones compared to MWA alone, with the most effective particle sizes being between 50-150 μm.
Acceleration of wound healing using adipose mesenchymal stem cell secretome hydrogel on partial-thickness cutaneous thermal burn wounds: An study in rats.

Background And Aim: The intricate healing process involves distinct sequential and overlapping phases in thermal injury. To maintain the zone of stasis in Jackson's burn wound model, proper wound intervention is essential. The extent of research on the histoarchitecture of thermal wound healing and the application of mesenchymal stem cell (MSC)-free-based therapy is limited.

Purpose: To utilize a novel ex vivo perfused human renal model and quantify microwave ablation (MWA) size differences in renal tissue when combining MWA with transarterial embolization (TAE).
Materials And Methods: Human kidneys (n = 5) declined for transplantation were obtained and connected to a fluoroscopy-compatible ex vivo perfusion system. Two ablations-1 standard MWA and 1 TAE-MWA-were performed in each kidney for 2 minutes at 100 W using a MWA system (Solero Angiodynamics).
A gray zone: Role of transesophageal echocardiography before atrial tachycardia catheter ablation.

Introduction: There is a lack of studies in the literature directly investigating the relationship between atrial tachycardia (AT) and left atrial (LA)/left atrial appendage (LAA) thrombus, and current guidelines do not provide strong recommendations regarding the use of transesophageal echocardiography (TEE) before AT catheter ablation. This study aims to elucidate the relationship between AT and the presence of LA/LAA thrombus and contribute to the literature on the use of TEE before AT catheter ablation.
Methods: This single-center retrospective observational study screened patients who underwent TEE between February 10, 2019, and February 10, 2023.
