Summary: This study evaluated the effect of lemon essential oil on salivary bacteria and volatile sulfur compound production in patients with halitosis. The results showed that lemon essential oil can inhibit the growth of salivary bacteria and reduce the production of volatile sulfur compounds in patients with halitosis.

Summary: This study evaluated the potential of exhaled breath analysis as a non-invasive method for diagnosing oral squamous cell carcinoma. Results showed elevated levels of hydrogen sulfide and methyl mercaptan in the exhaled breath of OSCC patients, suggesting that gas chromatography could serve as an accessory diagnostic tool for OSCC.

Summary: This study reviews the research on halitosis, discusses its various causes, and proposes effective interventions based on the underlying etiologies and mechanisms. Unhealthy eating habits and an imbalance of microorganisms in the oral cavity and gastrointestinal tract are identified as primary causes of halitosis. Dental caries, periodontal disease, xerostomia, and digestive disorders like gastritis and irritable bowel syndrome are also found to be related to the development of halitosis. Tailored interventions based on specific etiologies and mechanisms are crucial for addressing halitosis.

Summary: The review introduces the conventional and emerging methods for breath analysis in diagnosing and monitoring various diseases. It discusses the correlation between breath components and specific diseases, as well as unique ideas and devices for the diagnosis of common diseases through exhaled breath analysis. The potential application of exhaled breath analysis for diagnosing and screening different diseases is briefly introduced, offering a new avenue for non-invasive disease detection.

Summary: The study assessed the potential effects of four VSCs on the growth and oxidative status of Rhizobium sp. strain E20-8, showing that these compounds triggered similar antioxidant mechanisms in the presence of Cd. Specifically, DMDS and DMTS demonstrated protective effects at the membrane level.

Summary: Acute cardiorespiratory breathlessness is a significant cause of emergency hospitalizations. This study identified breath volatile organic compound biomarkers that can diagnose acute cardiorespiratory disease and investigated the metabolic enrichment patterns in acute disease. The findings demonstrate that the multibiomarker score can effectively differentiate acute disease from health and different subtypes of acute cardiorespiratory exacerbation. Furthermore, the study revealed specific enrichment patterns in different subgroups of acute disease.

Summary: Selenium-binding protein 1 (SELENBP1) acts as a methanethiol oxidase (MTO) in humans, converting methanethiol to hydrogen peroxide, hydrogen sulfide, and formaldehyde. Copper ions are essential for this MTO activity, as demonstrated by mutagenesis studies. Selenium binding, on the other hand, is not required for MTO activity. SELENBP1 ortholog SEMO-1 in the nematode C. elegans also requires copper ions for MTO activity. SELENBP1 degrades volatile sulfur compounds (VSCs), including methanethiol, suggesting its role in mitigating malodors.

Summary: Electronic nose (e-nose) is a new technology used to identify volatile organic compounds (VOC) in breath air. It can adequately identify airway inflammation in asthma patients. In this study, the e-nose was able to discriminate pediatric patients with asthma from controls, but the accuracy was lower in the external validation.

Summary: This study aimed to examine objectively measured halitosis levels based on the reasons individuals are concerned about halitosis. The results showed that individuals whose halitosis was pointed out by others had higher objectively measured halitosis levels, while those concerned about the attitudes of others or perceived their own halitosis had lower objectively measured halitosis levels.

Summary: Oral halitosis is a foul breath caused by local or systemic conditions, with volatile sulfur compounds (VSCs) being the main cause. The study found that using L-cysteine solution in gas chromatography can effectively differentiate the origin of oral halitosis, making it a useful tool for diagnosis.
