Evaluation of canine epidermis and keratinocytoids (keratinocytic organoids) by transmission electron microscopy. [PDF]

Vet Dermatol
Background – Skin disease is a common complaint in veterinary medicine. Current models often use live animals. Epidermal organoids (keratinocytoids) are 3D miniature organs created in culture from single epidermal keratinocytes. These keratinocytoids can be used as an alternative to live animal studies to investigate epidermal structures and skin ...

Histopathological characterisation of trunk‐dominant canine pemphigus foliaceus, and comparison with classic facial and insecticide‐triggered forms

Veterinary Dermatology, Volume 34, Issue 5, Page 425-440, October 2023., 2023
Background – While the clinical features were described recently, the histopathological characterisation of trunk‐dominant canine pemphigus foliaceus (PF) is lacking, and whether it differs from classic facial or insecticide‐triggered PF is unknown. Hypothesis/Objectives – This study describes the histopathological findings of trunk‐dominant PF, and ...

3D pollination biology using micro‐computed tomography and geometric morphometrics in Theobroma cacao

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Imaging technologies that capture three‐dimensional (3D) variation in floral morphology at micro‐ and nano‐resolutions are increasingly accessible. In herkogamous flowers, such as those of Theobroma cacao, structural barriers between anthers and stigmas represent bottlenecks that restrict pollinator size and access to reproductive ...

Thermoregulatory ability and mechanism do not differ consistently between neotropical and temperate butterflies

Global Change Biology, Volume 29, Issue 15, Page 4180-4192, August 2023., 2023
We studied how temperate and neotropical butterflies respond to temperature change. Neotropical butterflies were better at regulating their body temperature than temperate butterflies, mainly because at high air temperatures neotropical butterflies cooled themselves more.
