Microbial metabolites in tumor epigenetic regulation

open access: yesiMeta, EarlyView.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

FeCl3‐Catalyzed Synthesis of Ynones from Silylated Alkynes and Acetic Anhydride

open access: yesChemistryOpen, EarlyView.
The synthesis of alkynones from silylated alkynes and acid chlorides, first reported by Birkhofer in 1963, remains a valuable transformation. However, its reliance on stoichiometric AlCl3 and corrosive reagents raises environmental and practical concerns. To address this, a greener protocol using catalytic FeCl3 and acetic anhydride is developed.

DsiRNA‐mediated silencing of Ceratitis capitata transformer or transformer‐2 leads to masculinization of XX embryos and systemic gene silencing in ovaries

open access: yesInsect Science, EarlyView.
We carried out functional studies using Dicer‐substrate small interfering RNAs (DsiRNAs), targeting the sex determination genes Cctransformer (Cctra) and Cctransformer‐2 (Cctra‐2) in the Mediterranean fruit fly (Ceratitis capitata). Microinjection of DsiRNAs into XX embryos (0‐1 h old) rapidly triggered the expression of male‐specific Cctra isoforms ...

Solid Shampoo Is Mostly Not Preserved, in Contrast to Liquid Shampoos Used in Hairdressing—A Market Survey in Four European Countries

open access: yesContact Dermatitis, EarlyView.
Most solid shampoos (68.6%) did not contain preservatives according to Annex V of the EU Cosmetics Regulation (EC 1223/2009), while all liquid shampoos did. The number of preservatives used was significantly greater in liquid shampoos. ABSTRACT Background Hairdressers are frequently exposed to shampoos, both from neat liquid products and dilutions ...
