Article Abstract
Northeastern Thai ethnic foods are celebrated for their health benefits yet remain largely underexplored. This study assessed the antioxidant and cytotoxic properties of two ready-to-eat pastes-Jaew Hon (JH) and Gang Om (GO)-produced using laboratory (LAB) and industrial original equipment manufacturer (OEM) methods. Evaluations were conducted using 2,2-Diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), total phenolic content (TPC), and total flavonoid content (TFC) assays alongside the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay for cytotoxicity. Physicochemical analyses revealed that JH OEM had the highest total dissolved solids (11.57°Brix) and water activity (0.91), while GO OEM exhibited the highest pH (5.28) and lightness (L* 31.43). Antioxidant results showed JH LAB outperformed in DPPH scavenging (96.25 mg AAE/100 g) and TPC (433.5 mg GAE/100 g), whereas GO OEM achieved the highest TFC (345.57 mg QE/100 g). Volatile compound profiling by Gas Chromatography-Mass Spectrometry (GC-MS) indicated distinct aroma profiles between LAB and OEM samples. Moreover, MTT assays revealed stronger cytotoxic effects for OEM products; specifically, GO OEM achieved 71.88% maximum inhibition and an IC50 of 276.10 µg/mL against HT-29 cells. Colony formation assays confirmed GO OEM's significant antiproliferative activity, and gene expression analysis demonstrated upregulation of pro-apoptotic markers (, ) alongside downregulation of , , and . Overall, these findings suggest that industrially produced GO and JH pastes hold promise as functional foods, integrating traditional culinary practices with modern production techniques. These findings lay the foundation for future research focused on uncovering bioactive mechanisms, optimizing processing methods, and confirming health benefits through in vivo studies.

Research on worker exposure to volatile organic compounds (VOCs) during asphalt paving operations remains significantly limited, and regulatory frameworks governing such exposures are also insufficient. Previous studies have primarily focused on a limited number of major VOCs. However, this study employs high-resolution, high-performance Proton Transfer Reaction Time-of-Flight Mass Spectrometry (PTR-ToF-MS) to comprehensively evaluate exposure levels to 25 different VOCs.

Given that a variety of factors can affect the decomposition process, it can be difficult to determine the post-mortem interval (PMI). The process is highly dependent on microbial activity, and volatile organic compounds (VOCs) are a by-product of this activity. Given both have been proposed to assist in PMI determination, a deeper understanding of this relationship is needed.

The association of plants with beneficial soil microbes, including arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR), can enhance plant growth and nutrient uptake while modifying plant traits including growth rate, architecture, nutritional quality, secondary metabolites, phytohormones and volatile organic compounds (VOCs), necessary for interactions with insect pests and their natural enemies. Microbe-induced effects on insect herbivores and their natural enemies can be positive, neutral, or negative and are context dependent, creating the need for continued synthesis of published research to identify emerging patterns, recognize limitations, and guide future research. This perspective highlights three key pathways through which beneficial soil microbes drive interactions among agricultural plants, insect pests, and their natural enemies through the lens of applied research: (1) alterations in plant growth rate, architecture, and nutritional quality; (2) modifications of plant secondary metabolites and phytohormones; and (3) modifications in the emissions of volatile organic compounds.

This study systematically evaluated the inhibitory effects of model compounds from sludge-derived hydrothermal liquefaction aqueous phase (HTLaq) on anaerobic digestion (AD) at both mesophilic and thermophilic temperatures using a total of 1008 anaerobic toxicity assays (ATA). Twenty representative compounds of suspected inhibitors, including nitrogen-containing heterocyclics like pyridines, pyrrolidinones, and pyrazines, as well as phenols and ketones, were tested at varying dosages (25, 50, 100, 200, 400, and 800 mg/L) to assess their impact on volatile fatty acids (VFA) generation and consumption, methane production, substrate utilization, and inhibitory compound degradation. Results demonstrated that thermophilic AD is generally more susceptible to inhibition than mesophilic AD, both in terms of acute and chronic toxicity.
