Immune and physiological responses in to ammonia-N stress: a multi-omics approach.

Ammonia-N stress is a significant environmental factor that adversely affects the health and productivity of aquaculture species. This study investigates the effects of ammonia-N stress on the shrimp through a combination of biochemical, histological, transcriptomic, and metabolomic analyses. Shrimp were exposed to ammonia-N stress for 12 and 96 hours, and key markers of oxidative stress, nitrogen metabolism, immune response, and overall health were assessed.

Rational evaluation of the clinical application of ceftazidime-avibactam for the treatment of carbapenem-resistant Klebsiella pneumoniae infections: A real-world retrospective study.

Objectives: To evaluate the rationality of the clinical use of ceftazidime-avibactam (CAZ-AVI) for carbapenem-resistant Klebsiella pneumoniae (CRKP) infections in a real-world setting.

Methods: We established the rational evaluation criteria based on drug instructions and relevant guidelines to retrospectively evaluate the use of CAZ-AVI to treat CRKP infections from June 2020 to June 2023 in a tertiary hospital in China. Patients were divided into the rational use group and irrational use group.

Electronic Buffering Mechanism Enhances Stability and Water Oxidation Efficiency of CeO2@NiFe-LDH.

Nickel-iron layered double hydroxide shows significant promise as an electrocatalyst in facilitating oxygen evolution reactions. But its development is hindered by low conductivity and insufficient cycling stability. Herein, the synthesis of a hierarchically structured heterostructure catalyst, CeO2@NiFe LDH, is reported through a straightforward two-step process involving hydrothermal treatment.

[Absorption mechanism of iron oxide nanoparticles in Caco-2 cell model].

Objective: To explore the possible mechanism of absorption of iron oxide nanoparticles into the human body through the gastrointestinal tract.

Methods: This article used Caco-2 monolayer cells as a cell model, prepared characterized iron oxide nanoparticles(Fe_2O_3 NPs) as suspensions, and intervened in Caco-2 cells. CCK-8 method, transwell method, and atomic spectrophotometer method were used to explore the effect of Fe_2O_3 NPs on the activity of Caco-2 cells and the absorption and transport of them through the Caco-2 monolayer cell model.
