Detecting brain tumours (BT) early improves treatment possibilities and increases patient survival rates. Magnetic resonance imaging (MRI) scanning offers more comprehensive information, such as better contrast and clarity, than any alternative scanning process. Manually separating BTs from several MRI images gathered in medical practice for cancer analysis is challenging and time-consuming.

Improving the adsorption capacity of materials for pollutants by means of modification is an important direction in the research of water treatment technology. To improve the applicability of sodium alginate composites in the field of adsorption, magnetic sodium alginate-based hydrogel microsphere adsorbent material FeO@SA/PEI-Fe (FSPF) was synthesized in a single step by using polyethyleneimine grafting modification of sodium alginate by sol-gel method. The material was used for the removal of direct blue GL (DB 200) and direct date red B (DR 13) from simulated wastewater, as well as Cu(II) and Pb(II) from simulated wastewater with heavy metal ions.

Glioma is characterized by high heterogeneity and poor prognosis. Attempts have been made to understand its diversity in both genetic expressions and radiomic characteristics, while few integrated the two omics in predicting survival of glioma. This study was intended to investigate the connection between glioma imaging and genome, and examine its predictive value in glioma mortality risk and tumor immune microenvironment (TIME).

Background: We recently found region-specific patterns of iron-rich gliosis in frontotemporal lobar degeneration (FTLD) groups with tau (FTLD-Tau; PSP) and TDP-43 (FTLD-TDP) pathology using iron-sensitive MRI of whole-hemispheres. These patterns largely corresponded to regions of early pathology reported in previous traditional histopathologic staging schemes of protein inclusions for FTLD-Tau and FTLD-TDP. Ferritin light chain (FLC) reactivity highlights activated glia but has not been studied extensively in FTLD.

Background: Practice effects on cognitive testing in Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD) remain understudied, especially with how they compare to biomarkers of AD. The current study sought to add to this growing literature.
Method: Cognitively intact older adults (n = 68), those with amnestic MCI (n = 52), and those with mild AD (n = 45) repeated a brief battery of cognitive tests twice across one week, and they also completed a baseline amyloid PET scan, a baseline MRI, and a baseline blood draw to obtain APOE e4 status.
