DTPA and anti-inflammatory drug associations to alleviate Pu-induced response of macrophages in vitro.

Internal contamination by inhalation of plutonium poorly soluble compounds leads to their long time retention in alveolar macrophages inducing delayed pathology development. As previous studies highlighted co-localization of retained Pu and inflammatory lesions, this study was designed to assess the combined effect of the reference treatment (DTPA) and anti-inflammatory drugs on Pu-induced early response of macrophages in vitro. Pu colloids, mimicking poorly soluble Pu, were characterized using filtration and solid-state nuclear track detectors CR39.

Background: The clinical significance and optimal management of supranormal differential renal function (DRF ≥ 55%) in pediatric ureteropelvic junction obstruction (UPJO) remain debated. This study investigated supranormal DRF clinical characteristics and evaluated surgical versus conservative management outcomes to guide decision-making.
Methods: We retrospectively reviewed 76 children with unilateral UPJO who underwent standardized DMSA and DTPA scans at a single center (2020-2022).
Screening and prognostic roles of renal volumetry and scintigraphy in the assessment of living kidney transplant donors, considering the early recovery of the residual renal function.

Department of Urology, Nara Medical University, 840 Shijo-cho, Kashihara, Nara, 634-8522, Japan.
Background: The existing criteria for living kidney donors (LKDs)in Japan are controversial. We evaluated the roles of computed tomography volumetry (CTV) and 99 m Tc-diethylenetriamine penta-acetic acid (DTPA) scintigraphy in assessing preoperative and postoperative renal function and predicting early recovery of residual renal function.
Methods: We retrospectively reviewed the medical charts of 175 consecutive LKDs who underwent donor nephrectomy (DN) at our institution between 2006 and 2022.
Cancer-targeted pro-theranostic bi-metallic organo-coordination nanoparticles.

Cancer remains a leading cause of mortality, with aggressive, treatment-resistant tumors posing significant challenges. Current combination therapies and imaging approaches often fail due to disparate pharmacokinetics and difficulties correlating drug delivery with therapeutic response. In this study, we developed radionuclide-activatable theranostic nanoparticles (NPs) comprising folate receptor-targeted bimetallic organo-nanoparticles (Gd-Ti-FA-TA NPs).

Department of Nuclear Medicine (PET Center), Key Laboratory of Biological Nanotechnology of National Health Commission, Xiangya Hospital, Central South University, 87 Xiangya Road, Changsha, Hunan, 410000, China.
Purpose: The accurate assessment of inflammatory activity of the extraocular muscles (EOMs) in thyroid associated ophthalmopathy (TAO) is crucial for formulating subsequent treatment strategies and prognostic judgments. This study aims to explore the efficacy of using [Ga]DOTATATE PET/CT to assess the inflammatory activity of EOMs in TAO patients.
Procedures: This study enrolled 22 TAO patients and 6 healthy volunteers, all of whom underwent orbital [Ga]DOTATATE PET/CT.
