In this study, we investigated the effect of sintering temperature (1300, 1350, or 1400 °C) and holding time (1 or 2 h) on the mechanical properties of a cobalt-chromium (Co-Cr) alloy (Soft Metal) produced by milling/post-sintering, using a tensile test ( = 6). Prior to the test, the different nanostructures arising from the sintering conditions were also analyzed. The phase ratio of (face-centered cubic) phase to (hexagonal close-packed) phase increased mainly with increasing temperature. The formation of CrC carbide was greatest in the 1350 °C groups when compared to the other temperature groups. The 1400 °C groups had a substantially greater grain size than the 1300 °C and 1350 °C groups, together with a significant number of annealing twins inside the matrix phases. Overall, the 1350 °C groups showed the most superior properties. The 1400 °C groups showed a mean 0.2% yield strength under 500 MPa. The holding times did not significantly affect the mechanical properties ( > 0.05).

Sorting nexins (SNXs) as the key regulators of sorting cargo proteins are involved in diverse diseases. SNXs can form the specific reverse vesicle transport complex (SNXs-retromer) with vacuolar protein sortings (VPSs) to sort and modulate recovery and degradation of cargo proteins. Our previous study has shown that SNX3-retromer promotes both STAT3 activation and nuclear translocation in cardiomyocytes, suggesting that SNX3 might be a critical regulator in the heart.

Vertebral fracture assessment (VFA) images from bone density machines enable the automated machine learning assessment of abdominal aortic calcification (ML-AAC), a marker of cardiovascular disease (CVD) risk. The objective of this study was to describe the risk of a major adverse cardiovascular event (MACE, from linked health records) in patients attending routine bone mineral density (BMD) testing and meeting specific criteria based on age, BMD, height loss, or glucocorticoid use have a VFA in the Manitoba Bone Mineral Density Registry. The cohort included 10 250 individuals (mean 75.

In this study, screening of the collected 70 Salvia nemorosa L. populations from 54 habitats from West Azerbaijan province, Iran was evaluated by analyzing the content of phytochemical compounds, antioxidant activity, and UHPLC-HRMS profiling in different populations. The aerial parts of the plants were analyzed based on total phenolic (TPC) and flavonoid (TFC), total tannin (TTC), ascorbic acid (AAC), chlorophylls (Cla, and Clb), total carotenoid (TCC), β-carotene, antioxidant activity (by DPPH and FRAP assays), and 40 polyphenolic compounds by UHPLC-HRMS (phenolic acids, flavonoids and fatty acyl glicosides).

Background: Myogenic factor 6 (Myf6) plays an important role in muscle growth and differentiation. In aquatic animals and livestock, Myf6 contributes to improving meat quality and strengthening the accumulation of muscle flavor substances. However, studies on Myf6 gene polymorphisms in crustaceans have not been reported.
