Introduction: The results presented here are part of an investigation into the evolution of hydrothermal events associated with the Chicxulub impactites in Yu-catan, Mexico. The study focuses on alteration products in core samples recovered from the Yaxcopoil-1 drill hole, which is located some 60 kilometers from the center of the impact structure. This research contributes to the growing knowl...

In the article cited above, there are typographical errors in Table 3 with regard to the values for hospitalization for heart failure results. The results should state an incidence of 2.7% (126/4,687) with empagliflozin and 4.1% (95/2,333) with placebo, and the corresponding incidence rates should be 9.4/1,000 patient-years and 14.5/1,000 patient-years, respectively. The HR of 0.65 (95% CI 0.50...

A bone cryostat is described with which cold sections of unfixed, undemineralized calcified tissue can be prepared. The bone cryostat is suitable for the preparation of the sections required for the histochemical and immunofluorescent study of bone, for electron microprobe analysis, and for bone and joint autoradiography with soluble compounds.

Electron microprobe analyses of an extraordinarily large metal grain from the Murchison type 2 carbonaceous chondrite gave 0.24 mole percent silicon. Thermodynamic calculations show that this is a natural consequence of condensation of alloys from the solar nebular gas at a total pressure l0(-5) less, similar P(tot) < l0(-3) atmosphere, provided they failed to equilibrate with it after cooling ...
