Human Polyomavirus BK Genome Analysis in BKPyV Induced Rodent Cell Lines

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
In this study, we analyzed the BK polyomavirus (BKPyV) genome derived from three rodent cell lines established from BKPyV induced tumors. BKPyV derived one cell line had a large deletion. The noncoding control region (NCCR) of BKPyV derived from these cell lines had the same structure as viruses induced tumors.

Manganese Neurotoxicity and Familial Disorders of Manganese Transport

Annals of the Child Neurology Society, Volume 3, Issue 3, Page 135-144, September 2025.
ABSTRACT Manganese is the 12th most common element in the Earth's crust and is an essential industrial component. Biologically, this metal plays an important role as a constituent of numerous enzymes. While manganese is required for normal biochemical and physiological processes, manganese excess can lead to significant toxicity, particularly to the ...

The TP53 tumor suppressor gene: From molecular biology to clinical investigations

Journal of Internal Medicine, Volume 298, Issue 2, Page 78-96, August 2025.
Abstract Extensively studied over the past four decades, the TP53 gene has emerged as a pivotal watchman in cellular defense and a key factor in cancer biology. TP53 is the most frequently mutated gene in human malignancies, 50% of which carry alterations to it.

Congenital Intracranial Tumors: Prenatal Diagnosis by Fetal Magnetic Resonance Imaging

iRADIOLOGY, Volume 3, Issue 3, Page 203-208, June 2025.
Fetal intracranial tumors are rare, comprising 0.5%–1.9% of all childhood tumors, with their true incidence potentially underestimated. This review highlights the role of fetal MRI, particularly with advanced sequences, in diagnosing common fetal brain tumors such as teratomas, astrocytomas, and choroid plexus papillomas, often presenting unique ...

Imaging Assessment of the Pituitary Gland and Long‐Term Endocrinological Abnormalities in Pediatric Brain Cancer Survivors

Journal of Magnetic Resonance Imaging, Volume 61, Issue 6, Page 2516-2522, June 2025.
Background Pediatric brain cancer survivors often experience hypothalamic–pituitary dysfunction due to cranial irradiation and chemotherapy. While hormone deficiencies have been studied, the changes in pituitary size and shape on long‐term MRI and their relationship to endocrine dysfunction remain under‐explored.

The Cerebrospinal Fluid Secretion Rate Increases in Awake and Freely Moving Rats but Differs With Experimental Methodology

Advanced Science, Volume 12, Issue 17, May 8, 2025.
CSF dynamics are vital for neurological health. Yet accurate quantification of CSF rates is challenging. Using a novel technique in awake, freely moving rats, significantly higher secretion rates are found than in anesthetized rats. The findings highlight the importance of awake models and the adaptability of methods for studying CSF changes influenced
