Purpose: To propose an experimental burn model in NIH-3T3 cell line.
Methods: Induction of thermal injury in cultures of mouse fibroblast - NIH-3T3- cell line and determination of cell viability by MTT and immunofluorescence.
Results: The heating of the Petri dish increased proportionally to the temperature of the base and the time of exposure to microwave. In this in vitro burn model, using the cell line NIH-3T3 was observed drastic cellular injury with significant changes in cell viability and activity. It showed drastically modified cell morphology with altered membrane, cytoskeleton and nucleus, and low cellularity compared to the control group.
Conclusion: The burn model in vitro using the cell line NIH-3T3 was reproductive and efficient. This burn model was possible to determine significant changes in cell activity and decreased viability, with drastic change in morphology, cell lysis and death.

Acute lung injury being one of the earliest and most severe complications during sepsis and macrophages play a key role in this process. To investigate the regulatory effects and potential mechanisms of adipose mesenchymal stem cell derived-exosomes (ADSC-exo) on macrophages and septic mice, ADSCs-exo was administrated to both LPS-induced macrophage and cecal ligation and puncture (CLP) induced sepsis mice. ADSCs-exo was confirmed to inhibit M1 polarization of macrophages and to reduce excessive inflammation.

Background: Burns in children are often complex injuries, leading to prolonged length of stay (LOS) and significant morbidity. LOS in pediatric intensive care units (PICUs) is a key measure for evaluating illness severity, clinical outcomes, and quality of care. Accurate prediction of LOS is vital for improving care planning and resource allocation.

Introduction: Five million US Veterans had possible exposure to open burn pits used for waste disposal through service in Iraq (2003-2011) and Afghanistan (2001-2014). Burn pits generate toxic exposures that may be associated with adverse health outcomes. We examined all-cause and cause-specific mortality in relation to deployment to bases with open burn pits.

Reactive oxygen species (ROS) scavenging is a viable approach to promote corneal epithelium wound healing. This study created a single-component hydrogel (HA Gel) with a novel dual-functionalized hyaluronic acid derivative (HA-GA-PBA) containing gallol and phenylboronic acid (PBA) moieties. Both of these moieties were dual-functional.

Aims: This study aimed to investigate whether the histone deacetylase HDAC4 inhibitor, trichostatin A (TSA), could reverse resistance to non-depolarizing muscle relaxants (NDMRs) caused by burn injuries.
Materials And Methods: A rat burn injury model was established, in which TSA was administered to inhibit HDAC4 expression. The potency of rocuronium was assessed through tension tests, and the levels of HDAC4 and myogenin proteins were determined using Western blot.
