Predicting protein decomposition: the case of aspartic-acid racemization kinetics [PDF]

open access: yes, 1999
The increase in proportion of the non-biological (D-) isomer of aspartic acid (Asp) relative to the L- isomer has been widely used in archaeology and geochemistry as a tool for dating. The method has proved controversial, particularly when used for bones.

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

open access: yesAdvanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

Effect of post space treatment with adhesives on the push-out bond strength of fiber posts luted with self-adhesive resin cements

open access: yesActa Odontologica Turcica, 2017
Objective: The aim of this study was to evaluate the push-out bond strength of fiber posts used in the restoration of endodontically-treated teeth with extreme material loss, luted with two different self-adhesive resin cements alone or with the ...

Dynamic changes in ANGUSTIFOLIA3 complex composition reveal a growth regulatory mechanism in the maize leaf [PDF]

open access: yes, 2015
Most molecular processes during plant development occur with a particular spatio-temporal specificity. Thus far, it has remained technically challenging to capture dynamic protein-protein interactions within a growing organ, where the interplay between ...

Decoding Dental Stem Cell Aging: Mechanisms, Therapeutic Strategies, and Beyond

open access: yesAdvanced Science, EarlyView.
Dental stem cell (DSC) aging involves genomic instability, mitochondrial dysfunction, telomere attrition, and epigenetic alterations, leading to impaired proliferation, reduced differentiation potential, and pro‐inflammatory secretory activity. These processes drive cellular senescence and compromise regenerative and immunomodulatory functions, thereby

LPS‐Induced Mitochondrial Damage via SLC41A1‐Mediated Magnesium Ion Efflux Leads to the Pyroptosis of Dental Stem Cells

open access: yesAdvanced Science, EarlyView.
Lipopolysaccharide induces upregulation of the magnesium (Mg2+) efflux transporter solute carrier family 41 member 1 in dental stem cells, leading to a decrease in intracellular Mg2+ concentration and promoting the binding of oligomycin sensitivity‐conferring protein and cyclophilinD.
