Effective environmental monitoring is critical for preventing microbial and allergenic cross-contamination. However, manual swabbing methods, commonly used to verify hygienic conditions, are prone to inconsistent results because of variability in pressure, coverage, and techniques. Two novel solutions will be explored to address these challenges: a robotic swabbing system with tactile sensing control, and a fluorescence/absorbance spectrometer for non-contact, protein-based residue detection. The robotic system was evaluated against trained and untrained humans, measuring water pickup, surface coverage, and pressure consistency. Concurrently, the fluorescence system analyzed model poultry protein soil to correlate spectral patterns with contamination levels. The robotic system demonstrated statistically …

Canned tuna is susceptible to mislabeling due to its high consumer demand, complex global supply chains, and range of prices. DNA barcoding of a short fragment of the mitochondrial control region (CR), termed the CR mini-barcode, has been established as an effective method for tuna species identification. However, the high level of DNA degradation in canned tuna products reduces the effectiveness of this method. Therefore, this study aimed to compare CR mini-barcoding to targeted (i.e., real-time or multiplex) PCR-based methods to determine the most effective approach for canned tuna species identification. DNA was extracted in duplicate from 24 canned tuna …

Nanovesicles Derived From Protocorm-Like Bodies Of Dendrobium Officinal Enhance Corneal Epithelial Repair And Reduce Inflammation In Dry Eye Disease Models, Bao Yuqing, Peng Chengyu, Zhang Fenglei, Zheng Yuqiang, Zhang Mingqi, He Wei

Journal of Food and Drug Analysis

Plant-derived nanovesicles (PDNVs) offer a promising, biocompatible therapeutic platform. In this study, we isolatednanovesicles from protocorm-like bodies of Dendrobium officinale (PLBs-NVs) and evaluated their efficacy in dry eyedisease (DED) models. PLBs-NVs protected human corneal epithelial cells against hyperosmotic stress, supportedwound repair, and inhibited inflammation in vitro. In a desiccating stress-induced DED mouse model, topical PLBs-NVstreatment significantly restored tear secretion, reduced corneal epithelial damage, and lowered levels of proinflammatorycytokines. These results suggest that PLBs-NVs are a safe, natural, and effective therapeutic strategy for DED, sup-porting their potential for future clinical translation in ocular surface disorders.

Jujube seed extract (JSE), rich in polyphenols and flavonoids, exhibits neuroprotective and sleep-enhancing properties.In vitro, JSE protected HT22 cells against oxidative stress by activating the Nrf2/HO-1 pathway and upregulatingantioxidant enzymes. In vivo, JSE increased non-REM sleep and delta wave activity in pentobarbital- and caffeine-induced sleep models. Spinosin contributed to these effects. Long-term JSE administration upregulated GABAA, GABAB, and 5-HT1A receptors in brain tissue. These findings suggest that JSE offers dual benefits in mitigating oxidativestress and promoting sleep through antioxidant defense and neurotransmitter modulation, supporting its potential as a natural therapeutic agent.

Colorectal cancer (CRC) is one of the leading causes of cancer-related death globally and discovering novel therapeuticagents to treat the disease, and prevent cancer metastasis and recurrence is an urgent medical need. Cancer stem cells(CSCs) capable of self-renewal and differentiation are generally considered the cause of tumor metastasis, recurrenceand chemoresistance. Hence, targeting CSCs may be a promising strategy for the treatment of cancer. GATA6, a zincfinger transcription factor, contributes to tumorigenesis in CRC and is related to cancer stemness. GATA6-overexpressing stable clones OE4 and OE6 derived from HCT116 cells were previously established and exhibitedincreased stemness properties. In this study, we …
