Direct differentiation of human pluripotent stem cells into vascular network along with supporting mural cells

open access: yesAPL Bioengineering, 2023
During embryonic development, endothelial cells (ECs) undergo vasculogenesis to form a primitive plexus and assemble into networks comprised of mural cell-stabilized vessels with molecularly distinct artery and vein signatures. This organized vasculature

Vesicle associated membrane protein (VAMP)‐7 and VAMP‐8, but not VAMP‐2 or VAMP‐3, are required for activation‐induced degranulation of mature human mast cells [PDF]

open access: yesEuropean Journal of Immunology, 2008
AbstractMediator release from mast cells (MC) is a crucial step in allergic and non‐allergic inflammatory disorders. However, the final events in response to activation leading to membrane fusion and thereby facilitating degranulation have hitherto not been analyzed in human MC.

Enhancing generalized spectral clustering with embedding Laplacian graph regularization

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

A comparative morphological study of the ligamentum lamina nuchae and ligamenta interspinalia reveals enthesis patterns at the sites of attachment from the second to seventh cervical vertebrae in four extant species of Equus

open access: yesVertebrate Anatomy, Morphology, Palaeontology, 2020
Morphological variation in the attachment sites of the ligamentum lamina nuchae and ligamenta interspinalia to the 2nd to 7th cervical vertebrae is described in four species of Equus, and enthesis patterns in relation to these attachment sites are ...
