A histochemical study on the distribution of melanin in human oral epithelium at six regional sites

, 1991
Oral mucosa from six sites in 95 autopsies was tested for melanin using the Masson-Fontana silver reduction method. Melanin was detected in 51.6% of labial, 46.3% of palatal, 45.3% of buccal, 28.4% of mandibular gingival, 25.3% of lingual and 21.1% of ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

The Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

Perceptions of carotenoid and melanin colouration in faces among young Australian adults [PDF]

, 2018
Objective:  Human skin colour is influenced by three pigments: haemoglobin, carotenoids, and melanin. Carotenoids are abundant in fruits and vegetables, and when consumed accumulate in all layers of the skin, predominantly imparting yellowness (b*). This

Hair analysis of formoterol as a novel tool to assess long‐term inhalation medication adherence: Data from the TRICOLON trial

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this paper is to examine inhaled formoterol concentrations in hair and assess the potential of hair analysis as a tool for measuring long‐term adherence, by validation with objective data from digital inhalers. Methods Hair samples and digital inhaler data were collected from patients with COPD in 10 hospitals in the Netherlands as part ...
