Characterization of [18F]SMBT‐1 binding substrates in Alzheimer's disease and related disorders: A postmortem biochemical and immunohistochemical study

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Neuroimaging studies report associations of amyloid beta (Aβ) positron emission tomography (PET) with [18F](S)‐(2‐methylpyrid‐5‐yl)‐6‐[(3‐fluoro‐2‐hydroxy)propoxy]quinoline ([18F]SMBT‐1), a novel reactive astrogliosis surrogate radiotracer with high affinity for monoamine oxidase B (MAO‐B) in Alzheimer's disease (AD).

Investigation of Wall Effect on Packing Structures and Purge Gas Flow Characteristics in Pebble Beds for Fusion Blanket by Combining Discrete Element Method and Computational Fluid Dynamics Simulation

Applied Sciences
In a tritium-breeding blanket of a fusion reaction, helium, used as a tritium-purging gas, will purge the tritium breeder pebble beds to extract the tritium in blanket. The purge gas flow characteristics will affect the tritium extraction efficiency. The

Effect of packing structure on anisotropic effective thermal conductivity of thin ceramic pebble bed

Nuclear Engineering and Technology, 2021
Helium cooled solid breeder blanket as an important blanket candidate of the Tokamak fusion reactor uses ceramic pebble bed for tritium breeding. Considering the poor effective thermal conductivity of the ceramic breeder pebble bed, thin structure of ...

Synthesis and Characterization of Tritium‐Labeled Neuropeptide Y Y5 Receptor Ligands Derived From CGP71683A

Archiv der Pharmazie, Volume 359, Issue 8, August 2026.
From a synthesized series of 2,4‐diaminoquinazoline‐type Y5R ligands, three were prepared as tritium‐labeled compounds and characterized by saturation equilibrium binding at HEC‐1B‐hY5R cells. [3H]32 was further applied in a competition binding assay. High non‐specific binding of the radioligands prompted investigation of material‐dependent adsorption.

Build-up of tritium in a liquid-lithium breeding blanket for an inertial-confinement-fusion chamber [PDF]

, 1981
The build-up of tritium in a liquid lithium breeding blanket for an ICF chamber has been examined. The break-even time is found to decrease both the increasing tritium breeding ratio and increasing values of ..cap alpha.., the fraction of unburned ...

Machine Learning‐Based Profiling of Urinary Volatile Organic Compounds Reveals Distinct Diagnostic Signatures for Gastric Cancer

Cancer Medicine, Volume 15, Issue 8, August 2026.
ABSTRACT Introduction Gastric cancer (GC) is a leading cause of cancer‐related mortality worldwide, often diagnosed at advanced stages due to the absence of specific symptoms. This study aimed to explore the potential of urinary volatile organic compounds (VOCs) as non‐invasive biomarkers for gastric cancer diagnosis.

Tritium transport analysis in HCPB DEMO blanket with the FUS-TPC Code (KIT Scientific Reports ; 7642) [PDF]

, 2013
In thermonuclear fusion reactors, the fuel is an high temperature deuterium-tritium plasma, in which tritium is bred by lithium isotopes present inside solid ceramic breeder (e.g. Li-Orthosilicate) or inside liquid eutectic alloys (e.g.

Variability and Complexity of Environmental Drivers on Catchment Transit Times Across Space: A Systematic Review

WIREs Water, Volume 13, Issue 4, July/August 2026.
Environmental drivers influence or modulate transport processes that finally determine catchment transit times. TTD represents transit time distribution; MTT is the mean transit time; and Fyw means young water fraction. ABSTRACT Catchment transit time, the time water takes to travel from precipitation to streamflow, is a key diagnostic of how ...

Neutronic investigation of waste transmutation option without partitioning and transmutation in a fusion-fission hybrid system

Nuclear Engineering and Technology, 2018
A feasibility of reusing option of spent nuclear fuel in a fusion-fission hybrid system without partitioning was checked as an alternative option of pyro-processing with critical reactor system. Neutronic study was performed with MCNP 6.1 for this option,

Context‐Dependent Effects of Apolipoprotein A2 on Lipid Metabolism and Atherogenesis

The FASEB Journal, Volume 40, Issue 12, 30 June 2026.
Proposed model of the pro‐atherogenic role of APOA2 in dyslipidemia. Under conditions of dyslipidemia (ldlr−/− and apoe−/− mice), APOA2 promotes a reduction in VLDL through its conversion to LDL via an LDLR‐independent pathway. LDL is then deposited to the aorta and aortic root. In the ldlr−/− mice, the presence of APOE may mitigate the rate of VLDL to
