Article Abstract
Atomistic molecular dynamics simulations of dehydrated amorphous calcium carbonate interacting with the protein ovocleidin-17 are presented. These simulations demonstrate that the amorphisation of the calcium carbonate surface removes water structure from the surface. This reduction of structure allows the protein to bind with many residues, unlike on crystalline surfaces where binding is strongest when only a few residues are attached to the surface. Basic residues are observed to dominate the binding interactions. The implications for protein control over crystallisation are discussed.

Modifying cells to achieve desired functions has attracted extensive attention in bioengineering and bio-manufacturing. Approaches based on cell-surface engineering have the potential to endow cells with multiple functions and also create a protective shell around them. However, such shells are generally irreversible and lack functionality, leading to various drawbacks associated with irreversible dynamics.

Chimeric antigen receptor T (CAR-T)-cell therapy is a promising resolution for solid tumors, but its corresponding clinical translation has been hindered by unsatisfactory therapeutic potency and severe cytokine release syndrome. Herein, tetracycline (Tet)-On inducible human epidermal growth factor receptor 1 (HER1)-targeted CAR-T (Tet-HER1-CAR-T) cells were engineered to enable spatially selective activation at tumor sites by doxycycline (Doxy), which is delivered by pH-responsive stealth liposomal calcium carbonate nanoparticles (Doxy@CaCO-PEG). Compared with the intravenous administration of conventional HER1-CAR-T cells and Tet-HER1-CAR-T cells activated by free Doxy, concurrent intravenous administration of Tet-HER1-CAR-T cells and Doxy@CaCO-PEG leads to the localized tumor activation of Tet-HER1-CAR-T cells and reduced systemic secretion of inflammatory cytokines.

The development of functional materials for osteoporosis is essential for effective bone remodeling. In this context, the extraction of biocompatible implantable biomaterials from bio-waste emerges as a valuable strategy, addressing both environmental challenges and promoting human health. The objective of this work was to evaluate the physicochemical properties of the added-value by-product biomaterial (SS-90), extracted from sardine scales (Sardina Pilchardus) and combined with chitosan (SS-90-CH).

The rapid emergence of mineralized structures in diverse animal groups during the late Ediacaran and early Cambrian periods likely resulted from modifications of pre-adapted biomineralization genes inherited from a common ancestor. As the oldest extant phylum with mineralized structures, sponges are key to understanding animal biomineralization. Yet, the biomineralization process in sponges, particularly in forming spicules, is not well understood.

The purpose of this article was to study the distribution of left ventricular hypertrophy (LVH) and cardiac valve calcification (CVC), relevant factors, and the relationship of LVH and CVC with survival in maintenance hemodialysis (MHD) patients. A total of 281 MHD patients were included in this retrospective and follow-up study. Echocardiography measurements were performed to evaluate the left ventricular structure and cardiac valve.
