The present meta-analysis aimed to compare the adsorption capacity of metal–organic frameworks for the removal of volatile organic compounds in the gas phase. Based on the results of the 66 studies included in the meta-analysis, it can be inferred that a significant amount of research has been conducted in this area. MOFs are widely used for VOC removal due to their large specific surface area, high pore volume, and strong thermal resistance. This 2022 systematic review and meta-analysis were conducted in accordance with the PRISMA checklist. Five electronic databases were searched for this review (Medline/PubMed, Embase, Scopus, ISI Web of Knowledge, and Google Scholar). The most frequently used MOF and VOC were NH₂-MIL-125 and toluene, respectively. The findings of the present study indicate that MOFs are among the emerging materials commonly used for the removal of volatile chemical substances. The adsorption capacity of MOFs for non-polar VOCs can be improved by enhancing their hydrophobicity and modifying their metal species and spatial configuration. In addition, the organic linkers in MOFs may exhibit favorable interactions with organic solvents. Therefore, MOFs can be considered promising materials for the adsorption and removal of VOC gases. Furthermore, adsorption capacity may be further improved by increasing the surface area.

Exposure to industrial, military, and other occupational noises can cause noise-induced hearing loss (NIHL), which poses significant health risks for workers but is also potentially preventable. Currently, there is no effective treatment for NIHL, as mammalian cochlear hair cells cannot regenerate once damaged. Therefore, preventing hair cell death or implementing early therapeutic intervention is essential for preserving hearing function. NIHL is a complex condition that results from multiple pathophysiological changes. Recent studies on cochlear cellular structures have revealed promising strategies for NIHL prevention through the development of protective pharmacological agents. Reduced cochlear blood flow, inflammation, and oxidative stress are recognized as key mechanisms contributing to NIHL, with oxidative stress playing a particularly critical role. This research aimed to investigate the link between oxidative stress and the onset of NIHL, as well as to explore the potential of endogenous and exogenous antioxidant defense mechanisms in its prevention.
