Contact Urticaria and Related Conditions: Clinical Review

open access: yesContact Dermatitis, Volume 93, Issue 2, Page 87-107, August 2025.
ABSTRACT Contact urticaria (CoU) is an immediate contact reaction occurring within minutes to an hour after exposure to specific proteins or chemicals. CoU is categorised into non‐immunologic (NI‐CoU) and immunologic (I‐CoU) types, with I‐CoU potentially leading to anaphylaxis. Both forms of CoU can be associated with protein contact dermatitis and the

Diet C:N ratio and temperature influence the performance and colouration of tobacco hornworms

open access: yesEcological Entomology, Volume 50, Issue 4, Page 708-716, August 2025.
Melanization can help insects deal with environmental temperatures, but melanin synthesis can depend on nutrient availability. We tested whether the diet C:N ratio and temperature influence Manduca sexta performance and colouration. Larvae performed better at the warmer temperature of 27°C compared to 18°C and had a lighter colour when fed a low ...

Determination of Sorbic Acid in Wine

open access: yesJournal of AOAC INTERNATIONAL, 1974
Abstract A survey of a number of laboratories engaged in wine analysis showed that 2 basic techniques were used for the determination of sorbic acid. The first utilizes the absorbance by sorbic acid at 260 nm in acidic solution and the second depends on the oxidation of sorbic acid to malonaldehyde which is then reacted with ...
