Marked neurotropism and potential adaptation of H5N1 clade 2.3.4.4.b virus in naturally infected domestic cats.

In April 2024, ten cats died in a rural South Dakota (SD) residence, showing respiratory and neurological symptoms. Necropsy and laboratory testing of two cats confirmed H5N1 clade 2.3.

Tracing the origin of wood at the regional scale with dendrochemical markers: elemental and strontium and neodymium isotopic composition.

The dendrochemical approach holds significant promise for determining the geographical origin of wood as a complementary tool to dendroprovenancing based on tree-ring width. Tracing the origin of wood based on its elemental and isotopic composition is in particular interesting for provenance studies at the regional scale, as dendrochemical signatures are indicative of geological and pedological characteristics. Although, absorption of nutrients and trace elements reflects the composition of soil bioavailable pools, it is also modulated by multiple environmental and tree related factors.

Risk Factors for Reduced Long-Term Survival Following Isolated Surgical Aortic Valve Replacement in Different Age Groups.

Background: According to recent guidelines, the selection of transcatheter vs surgical aortic valve replacement (TAVR vs SAVR) in low-risk patients depends on age and life expectancy. Our objective was to understand independent risk factors for reduced life expectancy following isolated SAVR and the rate of redo aortic valve (AV) intervention in different age groups, to delineate optimal intervention depending on patient characteristics.

Methods: Between 2000 and 2015, 2026 patients underwent isolated SAVR with Carpentier-Edwards pericardial tissue valves (Edwards Lifesciences, Irvine, CA).

Impact of permanent dam opening on the fate of polycyclic aromatic compounds in industrial sludges accumulated on river banks: In situ approach.

The impact of permanent dam opening on the fate of organic contaminants was studied in the specific case of the Orne River industrial deposits. In the downstream part of the Orne River, the river banks were mainly constituted of steelmaking wastes accumulated for decades. Coring was performed before and after the permanent dam opening (performed in November 2019).
