Purpose Of Review: Tissue engineering is a rapidly expanding field in medicine and involves regeneration and restoration of many organs, including larynx and the airways. Currently, this is not included in routine practice; however, a number of clinical trials in humans are ongoing or starting. This review will cover publications during the past 2 years and the focus is on larynx and trachea.
Recent Findings: Recent reports concern the development and investigations of cell therapies, including biological factors such as growth factors which promote healing of damage and increased vascular support of the tissue. A separate section concerns studies of stromal cells and stem cells in tissue engineering. Cell therapies and treatment with biological active factors are often combined with the development of scaffolds to support or reconstruct the soft tissue in the larynx or the cartilages in trachea or larynx. New techniques for scaffold construction, such as 3D printing, are developed. The trend in the recent publications is to combine these methods.
Summary: Recent advances in tissue engineering of the larynx and trachea include the development of cell therapies or treatment with biological active factors often in combination with scaffolds.

The purpose of this study was to compare the penetration of methylene blue (MB) dye after laser irradiation using PIPS (photon-induced photoacoustic streaming) and SWEEPS (shockwave enhanced emission photoacoustic streaming) methods compared to Passive ultrasonic irrigation (PUI) and to study their effect on dentin microhardness. A total of 44 single-rooted human teeth which were extracted for orthodontic or periodontal reasons were used. The teeth were decapitated to standardize roots to 12 mm in length.

Due to its availability and biocompatibility, the human amniotic membrane (hAM) is being investigated by a large number of researchers with the goal of gaining a better understanding of the materials' mechanical behavior and structural integrity and optimizing them for various Tissue Engineering applications. In this research, biopolymers sodium alginate (SA) and silk fibroin (SF) were electrospun onto a decellularized hAM, resulting in two types of hybrid scaffolds: hAM/SF and hAM/SF/SA. The mechanical characteristics of these nanofibers were then analyzed to guide scaffold optimization for applications using these materials.

Invading blood cells, extracellular tissue, and soluble mediators all play important roles in the wound-healing process. There is a substantial global burden of disease and mortality attributable to skin defects that do not heal. About 1% to 2% of the population in industrialized nations suffers from chronic wounds that don't heal, despite healthcare breakthroughs; this condition is very costly, costing about $25 billion each year in the US alone.

Gastric ulcers (GUs) represent a common gastrointestinal disorder characterized by mucosal damage and inflammation, often precipitated by factors such as Helicobacter pylori infection and the consumption of COX inhibitors. This comprehensive review investigates the role of oxidative stress and inflammation in the pathogenesis of GUs and assesses the potential therapeutic effects of Punica granatum (pomegranate, Pg) supplementation. Utilizing a series of experimental models, including indomethacin, aspirin, and alcohol-induced ulcers, we demonstrate that Pg extracts possess significant gastroprotective properties.
