Dentifrices for preventing erosive tooth wear: An in vitro comparative study

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Erosive tooth wear is a progressive condition that compromises enamel structure and requires preventive strategies. This in vitro study aimed to compare the protective effects of fluoride‐based dentifrices containing various bioactive agents on sound enamel subjected to simulated erosive–abrasive challenges.

Diurnal and nocturnal salivary fluoride bioavailability following brushing with high‐ or regular‐fluoride dentifrices

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study evaluated salivary fluoride (F) bioavailability during diurnal and nocturnal periods after using a high‐fluoride or regular dentifrice. Fifteen healthy adults participated in a double‐blind crossover study, brushing with either a 1450 ppm F or 5000 ppm F dentifrice.

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

open access: yesThe FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Reinventing henna: Enzyme‐catalysed colour release from stabilized Lawsonia inermis L. extracts

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The instability and reduced dyeing performance of a cosmetic formulation containing 2‐hydroxy‐1,4‐naphthoquinone (lawsone), derived from Lawsonia inermis L., is demonstrated in comparison to a novel two‐component system. This system comprises one formulation with naturally occurring lawsone precursors and a second containing a specific hydrolase ...

A serum and cream moisturization regimen outperforms separate use in sustaining hydration, reducing TEWL, and balancing surface lipids over an 8‐h study

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Over 8 h, using a Hyaluronic Acid Serum in combination with a Moisturizing Cream sustained skin hydration more than either product alone, while lowering TEWL and normalizing surface lipids. Volunteers also reported a more immediate and long‐lasting moisturization with the combined regimen. Created in BioRender. Maldonado Lopez, A.
