The intestinal barrier is crucial for gut health, and its dysfunction can lead to chronic inflammatory conditions. Food contaminants like pesticides, heavy metals, mycotoxins, heterocyclic aromatic amines (HAAs), and polycyclic aromatic hydrocarbons (PAHs) may worsen these conditions. However, research often overlooks the complex interactions between contaminants and the different cells in the intestine.

This study investigates the presence of non-phthalate plastic additives (NPPAs), emerging contaminants increasingly used as alternatives to hazardous phthalates, in various water sources. To address their potential environmental and health risks, two complementary extraction methods were developed: direct immersion solid-phase microextraction gas chromatography coupled to Q-Orbitrap (DI-SPME-GC-Q-Orbitrap) and salting-out assisted liquid-liquid extraction combined with ultra-high-performance liquid chromatography (SALLE-UHPLC-Q-Orbitrap). The complementary use of these two methods makes it possible to analyse a larger number of analytes, 27 in particular, enabling the detection of 19 and 23 NPPAs by GC and LC, respectively (15 compounds were simultaneously monitored by both techniques), with limits of quantification (LOQs) ranging from 0.

A search is presented for an extended Higgs sector with two new particles, X and ϕ, in the process X→ϕϕ→(γγ)(γγ). Novel neural networks classify events with diphotons that are merged and determine the diphoton masses. The search uses LHC proton-proton collision data at sqrt[s]=13  TeV collected with the CMS detector, corresponding to an integrated luminosity of 138  fb^{-1}.

London rocket () is a wild green consumed globally, yet its phytochemical composition remains underexplored. In this study, we analyzed the leaves of wild plants and those grown in controlled environments (GCE) with varying electrical conductivities (EC) and light spectra. Plants were assessed for growth, phenolic content, vitamin C, antioxidant activity, glucosinolates, and antiproliferative effects against HT-29 human colorectal cancer cells.

Article Synopsis
  • The study focuses on detecting multijet signatures from proton-proton collisions at a high energy of 13 TeV, analyzing a dataset totaling 128 fb^{-1}.
  • A special data scouting method is utilized to pick out events with low combined momentum in jets.
  • This research is pioneering in its investigation of electroweak particle production in R-parity violating supersymmetric models, particularly examining hadronically decaying mass-degenerate higgsinos, and it broadens the limits on the existence of R-parity violating top squarks and gluinos.
