Re-sheathing failure with Navitor during transcatheter aortic valve implantation: a case report.
Eur Heart J Case Rep
January 2025
The Second Department of Internal Medicine, University of Toyama, 2630 Sugitani, Toyama, Toyama 930-0194, Japan.
Background: Self-expanding valves used in transcatheter aortic valve implantation (TAVI) are designed to allow recapture and repositioning, facilitating optimal placement and mitigating conduction disturbances and paravalvular leakage. Here, we present a rare case in which the Navitor (Abbott Structural Heart, Santa Clara, CA, USA) could not be recaptured.
Case Summary: An 81-year-old Japanese woman with very severe aortic stenosis and a massively calcified nodule at the non-coronary cusp (NCC) underwent TAVI with a 25 mm Navitor valve.
Effects of Conservation Agriculture on Soil NO Emissions and Crop Yield in Global Cereal Cropping Systems.

Conservation agriculture, which involves minimal soil disturbance, permanent soil cover, and crop rotation, has been widely adopted as a sustainable agricultural practice globally. However, the effects of conservation agriculture practices on soil NO emissions and crop yield vary based on geography, management methods, and the duration of implementation, which has hindered its widespread scientific application. In this study, we assessed the impacts of no-tillage (NT), both individually and in combination with other conservation agriculture principles, on soil NO emissions and crop yields worldwide, based on 1270 observations from 86 peer-reviewed articles.

The assessment of copper(I) and hydrogen interactions is challenging and should be approached with caution. In this paper, we report an assessment of multiple copper(I) and hydrogen interactions in two unique copper(I) thione cages. Copper(I) -heterocyclic thione cages [{Cu(-Br)(-L1)}] (1) and [{Cu(-I)(-L1)}] (2) were synthesized and characterized with proximity enforced Cu⋯H interactions.

Insulinoma-associated protein 1 (INSM1) is a relatively new immunostain used in the diagnostic assessment of tumors with neuroendocrine differentiation. While INSM1 positivity has been described in some non-neuroendocrine neoplasms, reactivity in red blood cells (RBCs) has only been anecdotally noted in one prior study without description of the degree/extent of staining. INSM1 staining in nucleated erythroid precursors has not been previously reported.
