A simple algorithm to derive virtual non-contrast electron density from dual-energy computed tomography data for radiotherapy treatment planning.
Med Phys
January 2025
Department of Chemistry, Faculty of Science, Hokkaido University, Sapporo, Hokkaido, Japan.
Background: The use of iodinated contrast-enhancing agents in computed tomography (CT) improves the visualization of relevant structures for radiotherapy treatment planning (RTP). However, it can lead to dose calculation errors by incorrectly converting a CT number to electron density.
Purpose: This study aimed to propose an algorithm for deriving virtual non-contrast (VNC) electron density from dual-energy CT (DECT) data.
Factors associated with statural growth in pediatric kidney transplant recipients with focus on metabolic acidosis.
Pediatr Nephrol
January 2025
CERTAIN Research Network, Heidelberg, Germany.
Background: We investigated factors associated with post-transplant growth in pediatric kidney transplant (KTx) recipients with a focus on plasma bicarbonate (HCO3) and estimated the effect of alkali treatment on growth.
Methods: In this study of the CERTAIN Registry, data were collected up to 5 years post-transplant. Generalized Additive Mixed Models were applied to assess the association between post-transplant growth and covariates.
Rhythms of light: Understanding the role of circadian timing in alertness and cognitive performance.

The nonimage-forming effects of light are pivotal in regulating cognitive functions, including alertness, sustained attention, and higher-order cognitive processes. These cognitive domains are deeply influenced by the sleep-wake cycle, which are governed by two key processes: the homeostatic process, which builds sleep pressure during wakefulness, and the circadian process, which aligns with environmental light cues to regulate wakefulness and sleep. When these processes fall out of sync-a condition known as circadian misalignment-alertness, sustained attention, and cognitive performance can suffer significantly.

Electronic address:
Magnetic nanoparticles effectively target drug delivery, contrast agents, biosensors, and more. Urchin-like magnetic nanoparticles (UMN) with abundant spike-like structures exhibit superior magneto-mechanical force to destroy tumor cells compared with other shapes of magnetic nanoparticles. However, when cell contents are released from tumor cells induced by magneto-mechanical force, they can act on surrounding tumor cells to facilitate tumor development.

Personality disorders (PDs) are psychiatric conditions characterized by enduring patterns of cognition, emotion, and behaviour that deviate significantly from cultural norms, causing distress or impairment. The aetiology of PDs is complex, involving both genetic and environmental factors. Genetic studies estimate the heritability of PDs at 30% to 60%, implicating genes involved in neurotransmitter regulation, such as those for serotonin transporters and dopamine receptors.
