An iterative nonlocal residual constitutive model for nonlocal elasticity [PDF]
arXiv, 2018 Recently, it was claimed that the two-phase local/nonlocal constitutive models give well-posed nonlocal field problems and eliminates the ill-posedness of the fully nonlocal constitutive models. In this study, it is demonstrated that, both, the fully nonlocal and the two-phase local/nonlocal constitutive models secrete ill-posed nonlocal boundary value

Aging Cell, Volume 24, Issue 6, June 2025.Direct activation and rejuvenation of aged fibroblasts through the application of mechanical forces in a 3D spheroid culture model. The ERK signaling pathway was revealed as a key underlying mechanism. ABSTRACT Age‐related changes in human dermal fibroblasts (HDFs) contribute to impaired wound healing and skin aging.

Chromosome mapping of 28S ribosomal genes in 11 species of Cassidinae (Coleoptera: Chrysomelidae)
European Journal of Entomology, 2017 In this study, we examined for the first time the distribution of the 28S ribosomal genes in beetles of the subfamily Cassidinae. More than 55% of the species in this subfamily have a similar karyotype, 2n = 16 + Xyp.

The FEBS Journal, Volume 292, Issue 11, Page 2715-2736, June 2025.The silencing of transposable elements is mediated by piRNAs through post‐transcriptional and transcriptional regulation. In Drosophila, piRNAs are processed within unique non‐membrane structures: nuage in germline cells and Yb bodies in somatic gonadal cells.

Journal of Neurochemistry, Volume 169, Issue 6, June 2025.(Figure created with Biorender.com. Publication license has been obtained with Biorender). ABSTRACT Alzheimer's disease (AD) involves cognitive decline, possibly via multiple concurrent pathologies associated with iron accumulation. To investigate if iron accumulation in AD is more likely due to pathological iron‐rich compartments, or a compensatory ...
