Background: The aging process of the face comprises all layers: skin, subcutaneous fat, muscles, and skeleton, and the signs of aging depend mainly on which layer is mostly affected.
Objective: To evaluate the aging facial skeleton, as well as establish the sexual differences, areas with a strong predisposition to resorption, and aesthetic repercussion for better treatment approach.
Methods: Skulls from the Forensic Anthropology Department of the Institute of Forensic Medicine of Belo Horizonte, Brazil, were classified according to gender and age group (i.e., <20 years, 20-50 years, >50 years). Structural changes were classified according to gender and age group.
Results: Of the 241 skulls included, 192 were male skulls and 49 female. Sexual dimorphism and age-related peculiarities are described herein.
Conclusions: The knowledge of the anatomy of the aging face, taking into consideration all the layers (skin, fat pads, muscles, and bones), as a whole, for the treatment of folds and shadows is vital for a better and more natural final aesthetic outcome.

Subjective eating disorder (ED) recovery has important clinical relevance. However, studies have focused on the perspectives of cisgender heterosexual individuals, which is notable given that sexual and gender minority (SGM) people often describe feelings misrepresented by prevailing ED conceptualizations. We examined eating pathology and psychosocial functioning across subjective recovery stages in SGM individuals ( = 196).

Background: Disease comorbidities and longer-term complications, arising from biologically related associations across phenotypes, can lead to increased risk of severe health outcomes. Given that many diseases exhibit sex-specific differences in their genetics, our objective was to determine whether genotype-by-sex (GxS) interactions similarly influence cross-phenotype associations. Through comparison of sex-stratified disease-disease networks (DDNs)-where nodes represent diseases and edges represent their relationships-we investigate sex differences in patterns of polygenicity and pleiotropy between diseases.

The hoarding behaviour of animals has evolved to reduce starvation risk when food resources are scarce, but effects of food limitation on survival of hoarding animals is poorly understood. Eurasian pygmy owls (Glaucidium passerinum) hoard small mammals and birds in natural cavities and nest boxes in late autumn for later use in the following winter. We studied the relative influence of the food biomass in hoards of pygmy owls on their over-winter and over-summer apparent survival.

Background: Trait variation is shaped by functional roles of traits and the strength and direction of selection acting on the traits. We hypothesized that in butterflies, sexually selected colouration is more variable owing to condition-dependent nature and directional selection on sexual ornaments, whereas naturally selected colouration may be less variable because of stabilising selection. We measured reflectance spectra, and extracted colour parameters, to compare the amount of variation in sexually versus naturally selected colour patches across wing surfaces and sexes of 20 butterfly species across 4 families (Nymphalidae, Papilionidae, Pieridae, Lycaenidae).
