Lower toxicity of HFPO-DA compared to its predecessor PFOA to the earthworm Eisenia fetida: Evidence from oxidative stress and transcriptomic analysis.

Hexafluoropropylene oxide dimer acid (HFPO-DA), an emerging perfluoroalkyl substance (PFAS) that is replacing traditional PFASs, has a wide range of industrial applications and has been detected globally in the environment. However, it remains unclear whether HFPO-DA, is genuinely less toxic than perfluorooctanoic acid (PFOA) in terms of soil environmental hazards. Therefore, this study aimed to compare differences in toxicity between PFOA and its substitute, HFPO-DA, in a common species of earthworm, Eisenia fetida.

Clinical surveillance of split renal function in kidney transplant recipients using Tc-diethylenetriamine-pentaacetic acid (DTPA) dynamic renal scintigraphy: preliminary findings and novel insights.

Background: En bloc kidney transplantation (EBKT) involves transplantation of two kidneys, the aorta, and inferior vena cava from a deceased pediatric donor into an adult recipient. Recent articles have shown that EBKT is associated with excellent long-term allograft performance and patient survival. Developmental differences exist between the two transplanted kidneys after EBKT, and it is crucial to assess split renal function.
