Article Abstract
We have successfully synthesized Sr(2)V(1-x)Mo(x)O(4) from x = 0.3 to 1.0 by an improved process. The layered compound Sr(2)VO(4) is an antiferromagnetic insulator with S = 1/2, while the isostructural Sr(2)MoO(4) is a Pauli paramagnetic metal. The solid solution Sr(2)V(1-x)Mo(x)O(4) of these materials is expected to show a metal-insulator transition. In this paper we report the synthetic process and the results of the magnetic susceptibility and the electrical resistivity. The selection of the starting materials and the adjustment of O(2) partial pressure of less than 10(-12) atm were indispensable for the synthesis. The reducing conditions during the sintering had been determined rationally, according to thermodynamical analysis. Kondo-like behavior in both resistivity and magnetic susceptibility were observed in a limited range of V-containing samples.

Background: A key limitation of the IMPACT model for prognostication after severe traumatic brain injury (TBI) is the use of predictors from hospital admission only. We sought to identify if including daily blood labs (e.g.

Introduction: Application of extracorporeal life support during cardiac arrest is termed extracorporeal cardiopulmonary resuscitation (eCPR). Mortality in pediatric patients undergoing eCPR for noncardiac conditions remains high and factors influencing survival are not well-defined. We hypothesized that eCPR survivors are more likely to have less severe electrolyte derangements prior to cannulation than nonsurvivors.

Sudden sensorineural hearing loss (SSNHL) is an acute hearing disorder that develops rapidly and is an otolaryngology emergency. Hyperbaric oxygen therapy (HBOT), a non‑pharmacological treatment, has gained increasing attention for SSNHL management. HBOT exerts therapeutic effects by increasing inner ear oxygen partial pressure, improving the microcirculation and reducing inflammation, as its main mechanisms.

While Aldo is believed to predominantly originate from the adrenal glands, this study provides evidence to support the involvement of intrarenal Aldo biosynthesis in the pathogenesis of ischemic nephropathy and hypertension in a two-kidney, one-clip (2K1C) model.
Methods: We generated inducible renal tubule-specific deletion of C11B2 (RT C11B2 KO) and characterized the phenotype during the 2K1C procedure.
Microbiome Diversity and Dynamics in Lotus-Fish Co-Culture Versus Intensive Pond Systems: Implications for Sustainable Aquaculture.

The lotus-fish co-culture (LFC) system leverages plant-fish symbiosis to optimize aqua-culture environments, enhancing both economic and ecological yields. However, the eco-logical mechanisms of microbial communities in LFC systems remain poorly understood, particularly regarding the functional roles of fungi, archaea, and viruses. This study compared microbiota (viruses, archaea, fungi) in water, sediment, and fish (crucian carp) gut of LFC and intensive pond culture (IPC) systems using integrated metagenomic and environmental analyses.
