Structural Characterization, Antioxidant Activity, and Biomedical Application of Astragalus Polysaccharide Degradation Products

International Journal of Polymer Science, 2018
To study the antioxidant capacity of Astragalus polysaccharides (APS) with different molecular weights, we used hydrogen peroxide to degrade original Astragalus polysaccharide (APS0) with an initial molecular weight of 11.03 kDa and obtained three ...

Deficiency of annexins A5 and A6 induces complex changes in the transcriptome of growth plate cartilage but does not inhibit the induction of mineralization [PDF]

, 2009
Initiation of mineralization during endochondral ossification is a multistep process and has been assumed to correlate with specific interactions of annexins A5 and A6 and collagens.

Biomineralization Kinetics of U(Ⅵ) on Bacillus sp.dwc-2

Yuanzineng kexue jishu, 2023
The U(Ⅵ) biomineralization on microorganisms will affect the chemical form and migration behavior of uranium in the environment. However, there are few studies on the kinetic behavior and the relevant mechanism of U(Ⅵ) biomineralization in the growth of ...

Biological niches within human calcified aortic valves. Towards understanding of the pathological biomineralization process [PDF]

, 2015
Despite recent advances, mineralization site, its microarchitecture, and composition in calcific heart valve remain poorly understood. A multiscale investigation, using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and ...

Biomineralization in perforate foraminifera [PDF]

Earth-Science Reviews, 2014
In this paper, we review the current understanding of biomineralization in perforate foraminifera. Ideas on the mechanisms responsible for the flux of Ca2 + and inorganic carbon from seawater into the test were originally based on light and electron microscopic observations of calcifying foraminifera.

Biophysical aspects of biomineralization [PDF]

Biophysical Reviews, 2017
During the process of endochondral bone formation, chondrocytes and osteoblasts mineralize their extracellular matrix (ECM) by promoting the synthesis of hydroxyapatite (HA) seed crystals in the sheltered interior of membrane-limited matrix vesicles (MVs).

Fungal biomineralization

Current Biology, 2021
Fungi are key organisms of the biosphere with major roles in organic-matter decomposition, element cycling, plant pathogenicity, and symbioses in aquatic and terrestrial habitats. The vast majority exhibit a filamentous, branching growth form and are aerobic chemoorganotrophs that derive carbon and energy from organic substances, and are particularly ...
