Objective The gastrointestinal environment in which drug products need to disintegrate before the drug can dissolve and be absorbed has not been studied in detail due to limitations, especially invasiveness of existing techniques. Minimal in vivo dat...

European Journal of Radiology, 130, Article 109196. https://doi.org/10.1016/j.ejrad.2020.109196

Purpose
The diaphragm is the most important muscle of respiration. Disorders of the diaphragm can have a deleterious impact on respiratory function. We aimed to evaluate the use of an open-configuration upright low-field MRI system to assess diaphra...

BACKGROUND:
Eating disorders are common in adolescence, devastating and strongly comorbid with other psychiatric disorders. Yet, little is known about their etiology to develop effective preventive measures.

METHODS:
Longitudinal assessments of... Read More about Development of Disordered Eating Behaviors and Comorbid Depressive Symptoms in Adolescence: Neural and Psychopathological Predictors.

Background

Persistent formal thought disorder (FTD) is a core feature of schizophrenia. Recent cognitive and neuroimaging studies indicate a distinct mechanistic pathway underlying the persistent positive FTD (pFTD or disorganized thinking), thoug...

Neocortical-hippocampal interactions support new episodic (event) memories, but there is conflicting evidence about the dependence of remote episodic memories on the hippocampus. In line with systems consolidation and computational theories of episod... Read More about Human hippocampal CA3 damage disrupts both recent and remote episodic memories.
