Plasma‐Polymerized Nanoparticles Presenting Fibrillin‐1 Drive Rapid Re‐Endothelialization of Vascular Grafts

Advanced Healthcare Materials, EarlyView.
Commercial vascular grafts are made from ePTFE, a highly hydrophobic, foreign material that fails at a high rate in small‐diameter applications. Plasma polymer nanoparticles (PPN) are a versatile material functionalisation tool, used here to present fibrillin‐1 fragment PF8 on the graft surface.

Episodic accretion at early stages of evolution of low mass stars and brown dwarfs: a solution for the observed luminosity spread in HR diagrams?

, 2009
We present evolutionary models for young low mass stars and brown dwarfs taking into account episodic phases of accretion at early stages of the evolution, a scenario supported by recent large surveys of embedded protostars.

Platelet Lysate–Enriched Human Induced Pluripotent Stem Cell–Derived Chondrocyte Sheets for Bone Defect Repair via Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
Human iPSC‐derived hypertrophic chondrocyte sheet promotes bone regeneration. Abstract Bone defects are a major clinical challenge, primarily owing to the limited self‐healing capacity of bones and the high risk of complications associated with conventional treatment strategies.

A modified method for molecular identification of Baylisascaris transfuga in European brown bears (Ursus arctos) [PDF]

, 2017
Baylisascaris transfuga is a roundworm that has been reported worldwide in most bear species. In mammals and possibly humans, the larvae of B. transfuga can migrate in the tissues of aberrant hosts with larva migrans syndrome.

Are grizzly bear and brown bear the same?

, 2023
Similarities and differences between Grizzly and Brown bears Grizzly bear and brown bear are two of the most iconic bear species that are often confused as being the same. While they do share many similarities, they are actually two different subspecies of the same species, Ursus arctos.

Patient‐Derived 3D Bioprinted Cardiac Organoid Constructs Reveal Key Pathological Features of Duchenne Muscular Dystrophy

Advanced Healthcare Materials, EarlyView.
Patient‐derived cardiac organoids reveal key features of Duchenne muscular dystrophy cardiomyopathy, including apoptosis, oxidative stress, calcium handling defects, and mechanical remodeling. By integrating organoids into alginate–gelatin bioprinted constructs, disease phenotypes are organized into scalable 3D cardiac tissues displaying extracellular ...

A preliminary baseline status of the Syrian Brown Bear Ursus arctos syriacus (Mammalia: Carnivora: Ursidae) in Golestanak, Northern Iran

Journal of Threatened Taxa, 2015
Baseline information is lacking for the Syrian Brown Bear across the sub-species range, making it difficult to assess at any level.  In the present investigation, our goal was to illustrate the population status of the Brown Bear in the Golestanak area ...

Systemic tuberculosis by MYCOBACTERIUM BOVIS in a free-ranging MARSICAN brown bear (URSUS ARCTOS MARSICANUS): a Case report

BMC Veterinary Research, 2019
Background Mycobacterium bovis is known to have a wide host range and has been isolated from numerous free-ranging wildlife species, carnivores included. In bears, M. bovis has been previously reported only from a culture of pooled lymph nodes of a black

Density and reproductive characteristics of female brown bears in the Cantabrian Mountains, NW Spain [PDF]

, 2018
Here we present annual nearest-neighbour distances (as a proxy of density) between females with cubs-of-the-year (hereafter FCOY) and reproductive characteristics of brown bears Ursus arctos in the Cantabrian Mountains (NW Spain), from 1989 to 2017. FCOY

Hybrid Nanofibers for Multimodal Accelerated Wound Healing

Advanced Healthcare Materials, EarlyView.
Fabrication of wound healing scaffolds based on biocompatible nanofibers. Nanofibers offering high surface area, flexibility, and biocompatibility significantly improved the healing outcome in vivo. Histological, immunological, and anti‐inflammatory markers are noticeably better in treated wounds.
