Construction of a Biomimetic Tubular Scaffold Inspired by Sea Sponge Structure: Sponge‐Like Framework and Cell Guidance

open access: yesAdvanced Science, EarlyView.
Inspired by the structure of sea sponges, a unique method involving microfluidic coaxial spinning and in situ polymerization is designed. Biomimetic tubular scaffolds ae fabricated. Composed of specific materials such as oxidized bacterial cellulose, bacterial cellulose and polydopamine, these scaffolds have excellent mechanical stability and ...

Variation and development of the turtle chondrocranium, with a description of the common musk turtle (Sternotherus odoratus, Kinosternidae, Cryptodira, Testudines)

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract Based on histological cross‐sections, the chondrocranium of the common musk turtle (Sternotherus odoratus) was reconstructed, described, and compared with other turtles. It differs from that of other turtle chondrocrania by possessing elongated, slightly dorsally orientated nasal capsules with three dorsolateral foramina, which might be ...

High‐Throughput Proteoform Imaging for Revealing Spatial‐Resolved Changes in Brain Tissues Associated with Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
High‐throughput proteoform imaging (HTPi) is established by combining matrix‐assisted laser desorption ionization mass spectrometry imaging and high‐sensitivity region‐specific top‐down proteomic analysis. HTPi enables the generation of annotated proteoform images with exceptional precision, high throughput, and deep coverage, showing distinct spatial ...

Neuroanatomical study of the podocnemidid turtle Neochelys arenarum (Pleurodira), from the early Eocene of France

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract Neochelys is an exclusively European Eocene podocnemidid genus belonging to a linage that reached this continent at the early Eocene. The so far available anatomical information about it is relatively abundant, especially considering that of its shell, at least partially preserved for the eight valid species currently considered.

A diffusion MRI model for random walks confined on cylindrical surfaces: Towards non-invasive quantification of myelin sheath radius [PDF]

open access: yes
Quantifying the myelin sheath radius of myelinated axons in vivo is important for understanding, diagnosing, and monitoring various neurological disorders. Despite advancements in diffusion MRI (dMRI) microstructure techniques, there are currently no models specifically designed to estimate myelin sheath radii.

Endothelial PD‐1 Regulates Vascular Homeostasis and Oligodendrogenesis during Brain Development

open access: yesAdvanced Science, EarlyView.
Vascular endothelial cells are fundamental for angiogenesis and brain development. This study reveals that endothelial programmed cell death 1 (PD‐1) is critical for cerebral angiogenesis and blood brain barrier (BBB) maturation. It also mediates interaction with oligodendrocyte precursor cells (OPCs), modulating OPCs differentiation and myelination ...
