Background: Quantitative molecular imaging via single-photon emission computed tomography-derived standardised uptake value (SPECT/CT-SUV) is used to assess the response of metastatic castration-resistant prostate cancer (mCRPC) patients to targeted radionuclide therapy (TRT) with [Lu]Lu-PSMA. This imaging technique determines the radiopharmaceutical distribution and internal dosimetry in patients who receive TRT. However, there is limited evidence regarding the role of image quantification in monitoring changes induced by [Lu]Lu-PSMA.

Plutonium-238 (Pu) is a scarce heat-source radioisotope used in nuclear batteries, which is produced by in-reactor irradiation of Americium-241 (Am) or Neptunium-237 (Np). Optimizing the neutron spectrum can improve the production efficiency of Pu, but currently, it is still a lack of knowledge about the optimal neutron spectrum for Pu production. Genetic algorithms and burnup algorithms are combined to identify optimal neutron spectra for Pu production under various irradiation times and flux levels, and build an optimal neutron spectrum database, which answers the questions "What is the optimal neutron spectrum for Pu production?" and "What is the maximum efficiency for Pu production" once and for all.

Background: Programmed cell death 1/programmed death ligand-1 (PD-L1)-based immune checkpoint blockade is an effective treatment approach for non-small-cell lung cancer (NSCLC). However, immunohistochemistry does not accurately or dynamically reflect PD-L1 expression owing to its spatiotemporal heterogeneity. Herein, we assessed the feasibility of using a Ga-labeled anti-PD-L1 nanobody, Ga-NODAGA-NM-01, for PET imaging of PD-L1.

Introduction: Mineral trioxide aggregate (MTA) is a calcium silicate-based cement that has changed conventional dental therapeutic approaches. This study aimed to evaluate physical, chemical and biological properties of novel AGM MTA, in comparison with MTA Angelus.
Methods: The samples were prepared according to the manufacturer's instructions.

The accumulation pattern of some inorganic pollutants in quarry sites around Ogun State was modeled using a Fuzzy comprehensive assessment (FCA). Potentially toxic elements (PTEs) and naturally occurring radionuclides materials (NORMs) were assessed from soil samples collected from ten quarry sites in three districts (Odeda, Ajebo, and Ijebu Ode) in Ogun State. Three (3) NORMs ( K, U, Th) were assessed using gamma spectrometer with a NaI detector while ten (10) PTEs (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) were determined by digestion method using Inductively coupled plasma optical emission spectrophotometer.
