Unraveling the parameters and biological mechanisms of CO2 laser therapy for acute pain relief

Frontiers in Neurology, 2023
Acute pain-related pathology is a significant challenge in clinical practice, and the limitations of traditional pain-relief drugs have made it necessary to explore alternative approaches. Photobiomodulation (PBM) therapy using CO2 laser has emerged as a

Temperature perturbation model of the opto-galvanic effect in CO2-laser discharges [PDF]

, 1984
A detailed discharge model of the opto-galvanic effect in molecular laser gas mixtures is developed based on the temperature perturbation or discharge cooling mechanism of Smith and Brooks (1979).

On the use of CO2 laser induced surface patterns to modify the wettability of Poly(methyl methacrylate) (PMMA) [PDF]

, 2010
CO2 lasers can be seen to lend themselves to materials processing applications and have been used extensively in both research and industry. This work investigated the surface modification of PMMA with a CO2 laser in order to vary the wettability ...

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

The comparison between microneedling and fractional CO2 laser for amniotic membrane stem cell-conditioned medium and vitamin C in photoaging treatment

Indian Journal of Dermatology, 2023
Context: Photoaging correlates with ultraviolet radiation (UVR). In addition to direct and indirect DNA damage, UVR leads to a breakdown of collagen, resulting in enlarged pores, visible wrinkles, also uneven skin tones and pigmentations.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.
