Summary: The purpose of this study was to determine the chemical composition of Lavandula officinalis essential oil and evaluate its antibacterial effects against seven pathogenic bacteria strains. The results showed that E. coli and S.newport were sensitive to the essential oil, and four strains were remarkably sensitive with MIC values of 88.7 μg/mL and 177.5 μg/mL. Molecular docking analysis indicated that eucalyptol and linalyl acetate efficiently bind with the active site of the target protein, showing higher activity than the positive control gentamicin.

Summary: Plectranthus L 'Her is a large genus of Lamiaceae family that includes about 300 species distributed in the tropical and warm regions of the Old-World. Some species are edible and used for traditional medicinal purposes in several countries. Phytochemical investigations have revealed that species in this genus contain diterpenoids with abietane, phyllocladanes, and kaurene skeleton. This study analyzed the essential oil composition of Plectranthus ornatus, an invasive and ornamental plant with traditional medicinal uses, for the first time in Israel, using gas chromatography-mass spectrometry (GC-MS). Comparisons were made with other essential oils from P. ornatus accessions.

Summary: The study investigated the presence of benzophenone in commercial sunscreen products, the increase in benzophenone concentration over time, and the source of benzophenone contamination from octocrylene degradation. The results showed that octocrylene can generate benzophenone through a reaction, and up to 70% of benzophenone in sunscreen products may be absorbed through the skin. Regulatory agencies should promptly review the safety of octocrylene as a benzophenone generator in SPF or any consumer products.

Summary: Pseudomonas aeruginosa, a critical priority pathogen with multidrug resistance, uses quorum sensing to collectively produce virulence factors. Fungal endophytes represent an under-explored source of novel quorum sensing inhibitors (QSI), with potential for discovering new antimicrobial agents. Lasiodiplodia venezuelensis, an endophytic strain, was found to have selective activity as a QSI against P. aeruginosa, leading to the isolation of compounds with anti-QS effects.

Summary: This study presents a simple and accessible method to detect, annotate, and quantify AHLs in bacterial culture media. The method utilizes an ultra-high-performance liquid chromatography system coupled with a mass spectrometer using a nontargeted FullMS data-dependent MS2 method. Results were processed using MZmine2 and analyzed by the Feature-Based Molecular Networking (FBMN) workflow in the Global Natural Products Social Networking (GNPS) platform. The study demonstrates the automatic annotation of known AHLs and the ability to search for unknown AHLs, even without analytical standards. The method also provides relative quantification information.

Summary: This study investigates the effects of octocrylene on two coral species and reveals that it can cause mitochondrial dysfunction and cellular senescence. The impact on a second coral species suggests that environmental octocrylene pollution may affect various reef-building species. Additionally, the research demonstrates that octocrylene can be modified by organisms and its contamination levels in the food chain may have been underestimated.

Summary: The extensive use of sunscreen products has caused concerns about their environmental toxicity and the negative effects they have on ecologically important coral communities. Metabolomic analyses on Pocillopora damicornis exposed to the UV filter avobenzone (BM) revealed unidentified ions in the coral's metabolome. Further analysis found that BM-exposed corals had 57 ions with significantly different relative concentrations, including 17 BM derivatives and one major derivative, C16:0-dihydroBM. These findings suggest that BM exposure may impair the photosynthetic capacity of coral holobionts and that the impact of BM derivatives should be considered in future environmental assessments.
