The role of phosphorylation and dephosphorylation of shell matrix proteins in shell formation : an in vivo and in vitro study [PDF]

, 2018
Protein phosphorylation is a fundamental mechanism regulating many aspects of cellular processes. Shell matrix proteins (SMPs) control crystal nucleation, polymorphism, morphology, and organization of calcium carbonate crystallites during shell formation.

Bamboo Medical Application: A State‐of‐the‐Art Review

Advanced Materials Technologies, EarlyView.
This review presents a structured classification of bamboo's current use in healthcare. It organizes applications into medical textiles and medical devices, with further divisions based on function and level of invasiveness. It also examines material utilization based on bamboo's structural role, highlighting how it supports both protective and ...

Production of single-domain magnetite throughout life by sockeye salmon, Oncorhynchus nerka [PDF]

, 1988
Although single-domain particles of biogenic magnetite have been found in different species of pelagic fishes, nothing is known about when it is synthesized, or about whether the time during life when it is produced is correlated with the development of

Dynamic Remodeling of the Magnetosome Membrane Is Triggered by the Initiation of Biomineralization [PDF]

, 2016
Magnetotactic bacteria produce chains of membrane-bound organelles that direct the biomineralization of magnetic nanoparticles. These magnetosome compartments are a model for studying the biogenesis and subcellular organization of bacterial organelles ...

Mechanical Overloading‐Induced Nanomineral Crystal Perturbation from the Osteochondral Interface: A Potential Initiator of Osteoarthritis

Advanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Sequencing and analysis of the gastrula transcriptome of the brittle star Ophiocoma wendtii [PDF]

, 2012
Background The gastrula stage represents the point in development at which the three primary germ layers diverge. At this point the gene regulatory networks that specify the germ layers are established and the genes that define the differentiated states ...

A Photothermal Transducer Regulates Transmembrane Calcium Flow for Synergistic Osteoarthritis Therapy

Advanced Science, EarlyView.
Upon NIR irradiation at 808 nm, the activity of TRPV4 was inhibited by M2M@BPSC, which led to reduced calcium influx, mitochondrial protection, and, importantly, the transcriptional activation of the STAT6‐EGR2 pathway. The improved macrophage function indirectly readjusts the equilibrium between C‐ECM and F‐ECM to reconstruct a suitable ...

Theoretical characterization of a model of aragonite crystal orientation in red abalone nacre

, 2009
Nacre, commonly known as mother-of-pearl, is a remarkable biomineral that in red abalone consists of layers of 400-nm thick aragonite crystalline tablets confined by organic matrix sheets, with the $(001)$ crystal axes of the aragonite tablets oriented ...

Nature's conveyor belt - the matrix mediated biomineralization of magnetite in chitons (Mollusca) [PDF]

, 2009
Chitons are marine molluscs that use a variety of iron and calcium based minerals to harden their teeth, which they use to scrape algae growing upon, and within, rocks.
