Le test d'allergie et le diagnostic de la péripneumonie bovine. I. Commentaires sur l'extraction de l'antigène protéique et étude expérimentale sur animaux de laboratoire

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1966
L'antigène protéique destiné aux tests d'allergie et préparé selon la méthode de R.N. GOURLAY (lyse par les ultra-sons et précipitation par le sulfate d'ammonium) est toujours plus ou moins contaminé par l'antigène lipopolyosidique de Mycoplasma mycoïdes.

Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties

open access: yesInternational Journal of Cosmetic Science, EarlyView.
UV exposure induces cuticular and cortical damage in natural hair, with oxidative effects and protein degradation comparable to bleaching. However, double bleaching leads to significantly greater structural degradation, emphasizing distinct mechanisms and severity of chemical versus UV‐induced damage. Abstract The combination of chemist techniques is a

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

open access: yesInternational 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 ...

Removal of bisphenol A by a nanofiltration membrane in view of drinking water production [PDF]

open access: yes, 2006
The efficiency with which a nanofiltration membrane (Desal 5 DK) removes bisphenol A(BPA) was investigated, together with the mechanisms involved. Whereas high retention (490%) was obtained at the beginning of the filtration, the observed retention ...

NPF2 is involved in intracellular pH regulation and ion balance in the diatom Phaeodactylum tricornutum

open access: yesNew Phytologist, EarlyView.
Summary Cellular ion and pH homeostasis are crucial factors affecting and regulating metabolic reactions, protein stability, signalling and transport mechanisms. To balance intracellular ion concentrations, organisms need to constantly sense and respond to both the extracellular environment and cell compartments' requests.
