Targeted keratin repair: A plant‐based approach to hair strength and surface restoration

International Journal of Cosmetic Science, EarlyView.
Application of Avena strigosa seed extract may reinforce keratin bonding, restoring hair fibre integrity by promoting intramolecular interactions at damaged sites of keratin proteins. Abstract Objective Chemical and thermal stress disrupts the intramolecular and intermolecular interactions that stabilize hair keratin, leading to structural degradation ...

Four Haylages, One Metabonome: Defining Diet Driven Metabolic Shifts in Ponies

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Haylage is widely fed to all categories of stabled horses across Europe and New Zealand. Haylage can vary from high energy nutrient dense forage to low energy highly fibrous fodder, yet little is known about the impact different haylages have on metabolism in horses.

Biosorption of an anionic dye by peanut shell modified with gemini surfactants: A study on the stability of the modification and the removal efficiency

, 2020
In this study, novel biosorbents were obtained from peanut shells modified with gemini-type surfactants. Peanut shells, an agro-industrial residue, were successfully modified to enhance their naturally low biosorption capacity towards anionic ...
