Summary: Volatile organic compounds (VOCs) are a diverse range of chemicals emitted from cells, organic matter, and fossil fuels. In the ocean, VOCs play important roles in the carbon cycle, influencing plankton growth, serving as info-chemicals, and altering Earth's radiative budget. Marine phytoplankton are the primary source of VOCs, with bacterioplankton consuming these compounds. Understanding VOC production and consumption can improve models predicting VOC emissions.

Summary: This study investigated the impairment of lipid metabolism induced by lead (Pb) and its amelioration through plant-based therapeutic interventions. Pb-induced hepatotoxicity disrupted the normal levels of antioxidant enzymes, leading to lipid peroxidation. Additionally, Pb toxicity altered the regulation of hormones involved in the synthesis of HMG-CoA reductase, resulting in abnormal levels of serum cholesterol and other lipid molecules. The administration of resveratrol effectively treated Pb toxicity. Overall, this study demonstrated the therapeutic effect of resveratrol in improving Pb-induced lipid metabolism impairment by using vitamin C as a standard intervention.

Summary: Oxygen scavengers play an important role in active packaging systems as they prevent food deterioration caused by oxygen. However, the release of volatile organic compounds (VOC) during the oxygen scavenging reaction is a concern. In this study, a multilayer oxygen scavenger system was designed using appropriate adsorbents to reduce the VOC release. The selected adsorbents effectively decreased the concentration of VOCs released from the oxygen scavenger films.

Summary: This study aimed to investigate the protective role of vitamin E in improving cardiotoxicity induced by cyclophosphamide in rats. The results showed that vitamin E could attenuate the elevation of cardiac markers, increase in lipid profiles, reduction in antioxidant enzyme activities, and increase in lipid peroxidation. In addition, vitamin E was found to improve the histopathological alterations caused by cyclophosphamide.

Summary: The polarity induced vapochromic and vapoluminescent properties of cationic poly-3-alkoxythiophene derivatives (PT) casted on polyvinylidene fluoride (PVDF) membranes are reported. The PT exhibit a rapid vapochromic response as well as a concurrent modulation of vapoluminescence, making it a potential platform for selective and sensitive VOC detection. The interaction between PT and VOC of varying polarities were ascertained using density functional theory (DFT) and principal component analysis (PCA) methodologies.

Summary: Breath analysis has great potential as a fast and non-invasive diagnostic tool for lung diseases. Straight-chain aliphatic aldehydes have been detected in the breath of patients using various methods such as mass spectrometry, ion mobility spectrometry, or electro-chemical sensors. Increased concentrations of exhaled aldehydes have been found in patients with lung cancer, inflammatory and infectious lung diseases, and mechanical lung injury.

Summary: This study evaluates the potential of volatile organic compounds (VOCs) as diagnostic and phenotypic biomarkers for irritable bowel syndrome (IBS). The results show that VOC analysis in breath and fecal samples can differentiate IBS patients from healthy controls and differentiate different subtypes of IBS patients. Furthermore, VOC models can differentiate IBS patients based on clinical characteristics.

Summary: Some plants have the ability to withstand severe environmental changes such as drought by losing cellular water and resuming full metabolic activity upon rehydration. During the rehydration process of the resurrection rustyback fern, a significant emission of volatiles, mainly fatty acid derivatives, was observed. Further analysis revealed the absence of certain hydrocarbons and terpenoids in the fern, suggesting its potential for bioactive compound production.

Summary: It has been found that solid lipid nanoparticles (SLNs), as a nanocarrier, can modulate the growth and antioxidant system of L. sativa seedlings through the controlled release of 2-ketones. The effect depends on the dose of the released compound.

Summary: Obesity is associated with various health issues, and abdominal fat is considered a serious risk factor for obesity-related diseases. The accumulation of visceral fat can promote the release of pro-oxidants, pro-inflammatory substances, and reactive oxygen species (ROS). Volatile organic compounds (VOCs) produced by the metabolic process in the human body can serve as biomarkers for obesity-related metabolic alterations and disease. This review focuses on the relationship between oxidative stress and VOCs in obesity.
