Highly sensitive ultra-high-performance liquid chromatography coupled with tandem mass spectrometry method for the multiplex analysis of levosimendan and its metabolites OR-1855 and OR-1896 in human plasma.

Levosimendan is a positive inotrope and vasodilator used in patients with acute and chronic decompensated heart failure. It is metabolized into OR-1855 (inactive metabolite), which is further acetylated into OR-1896 (active metabolite having a prolonged half-life, hence a sustained effect). Levosimendan represents a valuable alternative to traditional inotropes with broad clinical applications in critically ill patients with cardiogenic shock, advanced heart failure and post-cardiac surgery.

In Vivo Bioluminescence Imaging of Tumor Progression in the Lewis Lung Carcinoma Orthotopic Mouse Model: A Comparison Between the Tail Vein Injection and Intranasal Instillation Methods.

Metastasis remains a leading cause of cancer-related mortality, yet its study has been constrained by the lack of reliable animal models that faithfully replicate this complex process. Syngeneic models for studying lung cancer metastasis are limited, with the Lewis lung carcinoma (LLC) model being the most commonly employed. The conventional LLC orthotopic model involves injecting LLC cells intravenously (i.

I Feel I Remember: The Phenomenology of Autobiographical Recall in Individuals with Alcohol Use Disorder.

Introduction: Beyond the memory deficits classically observed in individuals with alcohol use disorder (IwAUD), research has recently focused on the study of autobiographical memory (AM) processes in IwAUD by analysing the content of AM narratives, and the implications for self-conception have been discussed. However, little is known about how IwAUD subjectively experience autobiographical recall.

Methods: Thirty-seven IwAUD and 37 control participants were invited to perform an AM task that involved recalling memories for 4 life periods (2 important memories per period).

[Acetazolamide and uveal effusion: report of two cases].

We report two cases of uveal effusion following oral acetazolamide administration: one case after a standard cataract surgery and a second following a preventive treatment for altitude sickness. The outcome in both cases was favorable. This rare complication requires appropriate management, including ruling out other pathologies.

Coastal current convergence structures in the Bay of Biscay from optimized high-frequency radar and satellite data.

The southeastern Bay of Biscay has been described as a "dead end" for floating marine litter, often accumulating along small-scale linear streaks. Coastal Current Convergence Structures (CCS), often associated with vertical motions at river plume edges, estuarine fronts, or other physical processes, can be at the origin of the accumulation. Understanding the formation of CCS and their role in the transport of marine litter is essential to better quantify and to help mitigate marine litter pollution.
