Investigation into the delivery and evaluation of a unique Avena sativa (Oat) Lipid Extract on skin barrier using LC‒MS/MS, Raman spectroscopy, immunostaining analysis and skin efficacy

International Journal of Cosmetic Science, EarlyView.
Abstract Objectives Oat lipids are rich in ceramides. In this investigation, we analysed the delivery of a specific Oat Lipid Extract derived from Avena sativa, comprising ‘skin identical’ ratios of fatty acids, ceramides and cholesterol/sterol. This investigation is the first reported investigation of oat lipids utilizing Raman spectroscopy for the ...

The Ti Plasmid‐Encoded VirJ Functions as a Lysyl‐Phosphatidylglycerol Hydrolase in Agrobacterium tumefaciens

Molecular Microbiology, EarlyView.
We identify the long‐known virulence factor VirJ as a lysyl‐phosphatidylglycerol (L‐PG) hydrolase. Like the chromosomally encoded virulence factor AcvB, it prevents excessive accumulation of L‐PG in the membrane, thereby maintaining efficient T‐DNA transfer via the Type IV secretion system (T4SS) in Agrobacterium tumefaciens.

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

Medical and Veterinary Entomology, EarlyView.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...

Polar Lipid and Fatty Acid Profiles of Oat Groats Substantially Influenced by Field Management: A Comparison of Cultivars, Sowing Times and Fertilizer Composition

Plant, Cell &Environment, EarlyView.
ABSTRACT The polar lipids in oat grains are crucial due to their biological functions, nutritional quality, potential use in food flavour and processing, the protection they provide against biotic and abiotic stresses, and their ability to act as cellular signalling molecules.
