Background: Sedation or anesthesia is often necessary in pediatrics when magnetic resonance imaging is performed. This anesthesia outside of the operation room combines specific requirements and risks. Ferromagnetic foreign bodies are a clear contraindication for magnetic resonance imaging due to the high magnetic field within the scanner. However, insertion of various small objects in mouth, nose or external auditory is not uncommon in small children and often remains unnoticed until specific symptoms develop. Early warning sings like movement of the object or heat development are then concealed by sedation or anesthesia preventing a timely termination of the possibly hazardous procedure.
Case Presentation: We present a case of a three year old Caucasian with an acute sinusitis due to unknown ferromagnetic foreign body in his nasal cavity. As soon as the suspicion was raised the procedure was aborted and the object that revealed to be a small button battery was successfully removed.
Conclusions: The potential of unwelcome side effects and effective safety strategies of magnetic resonance imaging are discussed as well as the complications arising from ingested batteries.

Combined use of cleft and truncated triangle signs helps improve the preoperative MRI diagnosis of lateral meniscus posterior root tears in patients with ACL injuries.

Purpose: This study aimed to investigate whether combining the analysis of different magnetic resonance imaging (MRI) signs enhances the diagnostic accuracy of lateral meniscus posterior root tears (LMPRTs) in patients with anterior cruciate ligament (ACL) injuries. We hypothesised that analysing the cleft, ghost and truncated triangle signs and lateral meniscus extrusion (LME) measurement together would improve the preoperative MRI-based diagnosis of LMPRTs.
Methods: This retrospective study used prospectively collected registry data from two academic centres, including patients undergoing primary or revision ACL reconstruction (ACLR) and LMPRT repair.

Changes in the microstructure of the aortic wall precede the progression of various aortic pathologies, including aneurysms and dissection. Current clinical decisions with regards to surgical planning and/or radiological intervention are guided by geometric features, such as aortic diameter, since clinical imaging lacks tissue microstructural information. The aim of this proof-of-concept work is to investigate a non-invasive imaging method, diffusion tensor imaging (DTI), in ex vivo aortic tissue to gain insights into the microstructure.

Loz1 is a zinc-responsive transcription factor in fission yeast that maintains cellular zinc homeostasis by repressing the expression of genes required for zinc uptake in high zinc conditions. Previous deletion analysis of Loz1 found a region containing two tandem CH zinc-fingers and an upstream "accessory domain" rich in histidine, lysine, and arginine residues to be sufficient for zinc-dependent DNA binding and gene repression. Here we report unexpected biophysical properties of this pair of seemingly classical CH zinc fingers.

Background: Biallelic pathogenic variants in the FUCA1 gene are associated with fucosidosis. This report describes a 4-year-old boy presenting with psychomotor regression, spasticity, and dystonic postures.
Methods And Results: Trio-based whole exome sequencing revealed two previously unreported loss-of-function variants in the FUCA1 gene.

Background: Degeneration of the basal forebrain cholinergic system is a hallmark feature shared by Alzheimer's disease (AD) and Lewy body disease (LBD) whereas hippocampus atrophy is more specifically related to AD. We aimed to investigate the relationship between basal forebrain and hippocampus atrophy, cognitive decline, and neuropathology in a large autopsy sample.
Methods: Data were obtained from the National Alzheimer's Coordinating Center (NACC).
