Facial attractiveness and preference of sexual dimorphism: A comparison across five populations [PDF]

open access: yes, 2021
A pesar de las intensas investigaciones, la psicología evolutiva aún no ha llegado a un consenso sobre la asociación entre dimorfismo sexual y atractivo. Este estudio examina las asociaciones entre el dimorfismo sexual facial percibido y morfológico y el

Genetic Ablation and Multi‐Omics Profiling Reveal CEP55 as a Key Driver of Tumorigenesis in Diverse Cancer Models

open access: yesAdvanced Science, EarlyView.
Genetic ablation of Cep55 in Pten‐deficient mouse models delays tumorigenesis. Integrated multi‐omics analyses (proteomics, phosphoproteomics, and spatial transcriptomics) reveal that CEP55 regulates oncogenic signaling (RAS/ERK, PI3K/AKT), integrin/FAK‐mediated adhesion, extracellular matrix (ECM) remodeling, and endocytosis.

Dimorphism in quaternary scelidotheriinae (mammalia, xenarthra, phyllophaga) [PDF]

open access: yes, 2015
The contributions concerning possible cases of sexual dimorphisms in fossil and living sloths are scarce. Until now, studies in fossil ground sloth sexual dimorphism have been limited to the subfamilies Megatheriinae (Eremotherium) and Mylodontinae ...

POLLEN DIMORPHISM IN THE RUBIACEAE [PDF]

open access: yesEvolution, 1956
The striking dimorphism of pollen and stigmata fonnd in the majority of the species of the tribe Staticeae in the Plumbaginaceae was discovered by McCleod (1887). This dimorphism and derived monomorphic conditions have been extensively investigated with results that have been found extremely helpful in the elucidation of genetical, genecological ...

Evolution of sexual size dimorphism in mammals: Sexual or natural selection? [PDF]

open access: yes, 2023
Sexual size dimorphism may have evolved through two processes: sexual or natural selection. The sexual selection theory states that males compete for mate monopolization and larger males can sire more offspring than smaller ones—factors that resulted in ...

Loss of SHP1 in Spinal Astrocytes Triggers T‐Lymphocyte Infiltration and Nociceptive Hypersensitivity

open access: yesAdvanced Science, EarlyView.
Astrocyte‐specific SHP1 deletion disrupts astrocyte–vascular interactions and compromises BBB integrity while enhancing STAT1‐dependent CXCL10 expression. These changes synergistically promote peripheral CD4+ and CD8+ T‐cell infiltration into the SDH. The infiltrating T cells secrete IFN‐γ, which in turn activates microglia.

Sexual dimorphism in dinosaurs

open access: yeseLife, 2023
Studying fossils from a mass-mortality event reveals evidence for sexual dimorphism and, unusually, equal numbers of males and females in a herd of dinosaurs.

A Decoy‐Receptor‐Armed Biomimetic Nanotherapeutic With Inherent Tropism for Conserved Pathogenic Macrophages for Treating Osteoarthritis and Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
A biomimetic doppelgänger nanosystem neutralizes extracellular inflammatory cytokines and silences intracellular pyroptosis, reprogramming pathogenic macrophages to attenuate both joint and spine degeneration. ABSTRACT Osteoarthritis (OA) and intervertebral disc degeneration (IVDD) are debilitating musculoskeletal disorders driven by shared ...

Sexual dimorphism in diaphyseal cross-sectional shape in the Medieval Muslim population of Écija, Spain and Anglo-Saxon Great Chesterford, UK

open access: yes, 2009
Differences in adult male and female activity patterns may influence levels of sexual dimorphism in physical dimensions, including the cross-sectional shape of long bone diaphyses.

Phase Separation of TRIM21 Modulates PTPN14 Stability to Drive Flow‐Dependent Endothelial Activation and Atherogenesis

open access: yesAdvanced Science, EarlyView.
Disturbed flow promotes the formation of TRIM21‐rich biomolecular droplets, which concentrate TRIM21 and PTPN14 and facilitate their SPRY‐FERM interaction (illustrated by the TRIM21 D355‐PTPN14 R132 salt bridge). This condensate‐driven proximity enables TRIM21 to catalyze K48‐linked polyubiquitination of PTPN14 at lysine 956, leading to proteasome ...
