Studies in sesquiterpenes-XLVI: Sesquiterpenes from the oleoresin of Dipterocarpus pilosus: humulene epoxide-III, caryophyllenol-I and caryophyllenol-II

, 1971
Oleoresin from Dipterocarpus pilosus has been shown to be a complex blend of sesquiterpenes (~18%) and triterpenoid-both tetracyclic and pentacyclic. A complete analysis of the sesquiterpene portion is reported. Besides the known caryophyllene, humulene,

Epidemiological, Clinical and Allergic Profile of Patients With Dyshidrotic Eczema (Acute and Recurrent Vesicular Dermatitis): Evaluation of the Spanish Registry of Research in Contact Dermatitis and Cutaneous Allergy (REIDAC)

Contact Dermatitis, EarlyView.
In this exploratory analysis, dyshidrotic eczema demonstrated a distinct sensitisation pattern compared with non‐dyshidrotic hand eczema. The lower proportion of clinically relevant reactions amongst positive patch tests suggests a multi‐factorial and not exclusively allergic background.

Attractiveness of Melon Genotypes to Whitefly (Bemisia tabaci) Mediated by Foliar Morphological and Biochemical Traits

Entomologia Experimentalis et Applicata, EarlyView.
This study identifies melon genotypes resistant to Bemisia tabaci by integrating morphological and biochemical leaf traits. Using free‐choice and no‐choice assays, we demonstrate that resistance is primarily mediated by antixenosis. Genotypes CNPH 11‐1071‐43, CNPH 06‐1047‐343, CNPH 13‐1076, and BG MEL 16 significantly reduced whitefly settling and ...
