ABSTRACT A 66‐year‐old man presented with a 5‐year history of recurrent pruritic, waxy folliculocentric papules on his trunk which worsened during winter and minimally responded to selenium sulphide shampoo and topical corticosteroids. Skin biopsy demonstrated a dilated follicular infundibulum containing abundant yeasts and amorphous material with ...

Ultrastructure of Plant Leaf Cuticles in relation to Sample Preparation as Observed by Transmission Electron Microscopy [PDF]
The leaf cuticular ultrastructure of some plant species has been examined by transmission electron microscopy (TEM) in only few studies. Attending to the different cuticle layers and inner structure, plant cuticles have been grouped into six general ...

ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Micromorpho‐anatomical studies on the leaves and woods of Turkish Daphne (Thymelaeaceae) taxa
The identification of Daphne taxa is difficult because of the lack of available morphological characteristics. Here, we aimed to describe leaf and wood micromorpho‐anatomical characteristics of native Turkish Daphne taxa (D. glomerata, D. gnidioides, D. mezereum, D. mucronata, D. oleoides subsp. kurdica, D. pontica and D.

Wax Lipids from Leaf Surfaces of Some Common plants of Malaysia [PDF]
Epicuticular wax lipids from leaves of some common plant species found in the Klang Valley, Malaysia were extracted into dichloromethane for analysis. Extracts were separated into hydrocarbon, carboxylic acid, ketone and alcohol fractions. The fractions

The agricultural industry requires improved efficacy of sprays being applied to crops and weeds to reduce their environmental impact and increase financial returns. One way to improve efficacy is by enhancing foliar penetration. The plant leaf cuticle is

Leaf surface wettability and fatty acid composition of Arbutus unedo and Arbutus andrachne grown under ambient conditions in a natural macchia [PDF]
Features of the adaxial and abaxial surface microstructure of Arbutus unedo L. and Arbutus andrachne L. are evaluated as possible consistent parameters contributing to the wetness of leaves. The abaxial leaf surface of A. andrachne and A.

ABSTRACTThe cuticle, an extracellular hydrophobic layer impregnated with waxy lipids, serves as the primary interface between plant leaves and their environment and is thus subject to external cues. A previous study on poplar leaves revealed that environmental conditions outdoors promoted the deposition of about 10‐fold more cuticular wax compared to ...

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Leaf Optical Responses to Light and Soil Nutrient Availability in Temperature Deciduous Trees [PDF]
Leaf optical parameters influence light availability at the cellular, leaf, and canopy scale of integration. While recent studies have focused on leaf optical responses to acute plant stress, the effects of changes in plant resources on leaf optics ...
