Potato is the fourth-most important food crop around the world, and most of the potatoes are used for foodstuffs and starch products. The aim of this paper is to identify the volatile compounds and metabolites in potatoes with different processing properties. The results showed large differences of volatile and metabolite compounds such as 2,4-Heptadienal and rhoifolin in potatoes and indicated the potential regulations between volatile compounds and metabolites. Moreover, the differences in volatile and metabolite compounds were compared between fresh eating and processing type potatoes. Compared to process type potatoes, fresh eating potatoes contained a higher proportion of aldehyde and alcohol compounds, but being lower in hydrocarbon, furan, and ketone compounds. Moreover, the different expressed metabolites were involved in the metabolism of amino acids, flavone and flavanol biosynthesis, and tryptophan metabolism. The Random forest showed that the fresh eating and processing type potatoes could be distinguished by the content of amino acids and phenols.

Fraud in alcoholic beverages through counterfeiting and adulteration is rising, significantly impacting companies economically. This study aimed to develop a method using near-infrared (NIR) spectroscopy (1596-2396 nm) through the bottle, along with machine learning (ML) modeling for beer authentication, quality traits, and control assessment. For this study, 25 commercial beers from different brands, styles, and three types of fermentation were used.

Background: Total intravenous anesthesia (TIVA)-based and volatile-based general anesthesia have different effects on cerebral hemodynamics. The current work compares these 2 regimens in acute ischemic stroke patients undergoing endovascular therapy.
Methods: We conducted a systematic literature search across MEDLINE, Embase, Cochrane, CINAHL, Web of Science, and Scopus.

Ionic liquids (ILs) are widely used "green solvent" as they have a low vapor pressure and can replace volatile solvents in industry. However, ILs are difficult to biodegrade and are potentially harmful to the environment. This study, herein, investigated the toxicity of three imidazole ILs ([CMIM]Cl, [CMIM]Br, and [CDMIM]Br) towards soil microorganisms.

Perioperative neurocognitive disorders (PND) is a common complication affecting the central nervous system, commonly induced by anesthesia and surgical procedures. PND has garnered considerable attention in recent years, not only due to its high morbidity but also its negative impact on patient prognosis, such as increased rates of dementia and mortality. Sevoflurane, a common volatile anesthetic in clinical practice, is increasingly linked to being a potential risk factor for PND with prolonged inhalation, yet effective prevention and treatment methods remain elusive.

Monitoring persistent organic pollutants (POPs) with endocrine-disrupting properties poses significant analytical challenges due to labor-intensive, costly, and environmentally unsustainable procedures. This study developed an efficient and robust approach for the simultaneous detection of diverse groups of semi-volatile organics in water and sediment samples using gas chromatography-tandem mass spectrometry (GC-MS). Two extraction methods were studied for determining POPs in water and sediments.
