Maternal overweight and obesity during pregnancy and sex‐dependent dysregulation of the materno‐fetal stress axis

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Maternal obesity and excess gestational weight gain (GWG) are linked to adverse perinatal outcomes, potentially via disruption of the maternal–fetal stress axis. Placental HSD11B2 protects the fetus from excess glucocorticoids and may influence fetal programming during maternal metabolic stress.

Ecological Aspects of Sexual Dimorphism

, 2017
Sexual dimorphism represents a striking source of diversity in nature. This thesis focuses on empirically testing and conceptually unifying some of the non-exclusive adaptive causes of sexual dimorphism.

Sexual dimorphism in hormone–gut microbiome associations across reproductive states in wild giant pandas

iMetaOmics, EarlyView.
Gut microbiota–host endocrine interactions in wild mammals remain poorly understood. Giant pandas experience seasonal dietary shifts and constrained annual reproduction, offering an ideal model to investigate microbiome–endocrine coupling. We integrated fecal hormone profiling, microsatellite‐based individual identification, and gut microbiome ...

Mapping the subgingival HerBiome and HisBiome over the human healthspan

Journal of Periodontology, EarlyView.
Abstract Background Understanding the intricate relationship between sex, age, and the oral microbiome is crucial for deciphering the onset and progression of numerous age‐related oral and systemic diseases. Methods Subgingival plaque was collected from 781 periodontally and systemically healthy females and 160 males spanning 0 to 80 years.

Astragalus ecomorphology in Quaternary elephantids

Journal of Quaternary Science, EarlyView.
ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...

A Modern Metrical Baseline for Sexing Sheep Horn‐Cores

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Sex determination is essential for reconstructing past livestock management, yet the limited skeletal sexual dimorphism of sheep hinders the identification of ewes, rams, and wethers in archaeological assemblages. Horn‐cores are the most sexually dimorphic element of the sheep skeleton, and here, we establish a new metrical baseline for ...

Sexual dimorphism of the human fetal pelvis exists at the onset of primary ossification

Communications Biology
Human adolescent and adult skeletons exhibit sexual dimorphism in the pelvis. However, the degree of sexual dimorphism of the human pelvis during prenatal development remains unclear. Here, we performed high-resolution magnetic resonance imaging-assisted

Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

Oikos, EarlyView.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...
