    Abstract The store-operated calcium channels Orai1-3 form extraordinary long and funnel like pores, in stark contrast to a classical pore loop architecture. A hydrophobic segment centrally located in the Orai pore controls gating. Here, we comment on a recent work that describes decisive binding between three residues that controls the open and closed conformation of Orai channels.

    Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection has been associated with musculoskeletal manifestations, including a negative effect on bone health. Bone formation was found to be reduced in coronavirus disease 2019 (COVID-19) patients. The aim of this case-control study was to determine whether bone metabolism is coupled or uncoupled in COVID-19 patients with moderately severe disease, the latter expressed by the requirement of hospitalization but not intensive care treatment, no need for mechanical ventilation, and a C-reactive protein level of (median [quartiles], 16.0 [4.0; 52.8]) mg/L in serum. Besides standard biochemical markers, serum levels of C-terminal telopeptide of type 1 collagen, tartrate-resistant acid phosphatase, osteocalcin, bone-specific alkaline phosphatase, sclerostin, dickkopf-1, and osteoprotegerin were evaluated in COVID-19-infected patients at the time of hospital admission, along with those of age- and sex-matched noninfected controls. The median age of the 14 female and 11 male infected patients included in the matched-pair analysis was (67 [53; 81]) years. C-terminal telopeptide of type 1 collagen was significantly lower in COVID-19 patients (0.172 [0.097; 0.375] ng/mL) than in controls (0.462 [0.300; 0.649] ng/mL; p = 0.011). The patients' osteocalcin levels (10.50 [6.49; 16.26] ng/mL) were also lower than those of controls (15.33 [11.85, 19.63] ng/mL, p = 0.025). Serum levels of sclerostin and dickkopf-1 were significantly higher in infected patients relative to controls. The remaining parameters did not differ between cases and controls. A limitation of the study was that patients and controls were recruited from different hospitals. Nevertheless, due to the geographical proximity of the two centers, we assume that this fact did not influence the results of the study. Given this limitation, the investigation showed that bone metabolism is altered but remains coupled in patients with moderately severe COVID-19. Therefore, it is important to evaluate bone turnover markers and fracture risk in these patients during the postinfection period. © 2023 The Authors.

    Abstract Magnesium (Mg)-based implants are promising candidates for orthopedic interventions, because of their biocompatibility, good mechanical features, and ability to degrade completely in the body, eliminating the need for an additional removal surgery. In the present study, we synthesized and investigated two Mg-based materials, ultrahigh-purity ZX00 (Mg-Zn-Ca; <0.5 wt% Zn and <0.5 wt% Ca, in wt%; Fe-content <1 ppm) and ultrahigh-purity Mg (XHP-Mg, >99.999 wt% Mg; Fe-content <1 ppm), in vitro and in vivo in juvenile healthy rats to clarify the effect of the alloying elements Zn and Ca on mechanical properties, microstructure, cytocompatibility and degradation rate. Potential differences in bone formation and bone in-growth were also assessed and compared with state-of-the-art non-degradable titanium (Ti)-implanted, sham-operated, and control (non-intervention) groups, using micro-computed tomography, histology and scanning electron microscopy. At 6 and 24 weeks after implantation, serum alkaline phosphatase (ALP), calcium (Ca), and Mg level were measured and bone marrow stromal cells (BMSCs) were isolated for real-time PCR analysis. Results show that ZX00 implants have smaller grain size and superior mechanical properties than XHP-Mg, and that both reveal good biocompatibility in cytocompatibilty tests. ZX00 homogenously degraded with an increased gas accumulation 12 and 24 weeks after implantation, whereas XHP-Mg exhibited higher gas accumulation already at 2 weeks. Serum ALP, Ca, and Mg levels were comparable among all groups and both Mg-based implants led to similar relative expression levels of Alp, Runx2, and Bmp-2 genes at weeks 6 and 24. Histologically, Mg-based implants are superior for new bone tissue formation and bone in-growth compared to Ti implants. Furthermore, by tracking the sequence of multicolor fluorochrome labels, we observed higher mineral apposition rate at week 2 in both Mg-based implants compared to the control groups. Our findings suggest that (i) ZX00 and XHP-Mg support bone formation and remodeling, (ii) both Mg-based implants are superior to Ti implants in terms of new bone tissue formation and osseointegration, and (iii) ZX00 is more favorable due to its lower degradation rate and moderate gas accumulation.
