Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Heterogeneity of the adult mammalian forebrain neurogenic ependyma: A comprehensive cellular map

Neural Regeneration Research
The presence or absence of adult neural stem cells in the mammalian forebrain ependyma has been debated for two decades. In this study, we performed single-cell RNA sequencing to investigate the cellular composition of the ependymal surface of the adult ...

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

A sequential cell therapy to recover the ependymal cells in posthemorrhagic hydrocephalus. [PDF]

, 2022
Background Germinal matrix haemorrhages and intraventricular haemorrhages (GMH/IVH) lead to posthemorrhagic hydrocephalus (PHH), a relevant cause of morbidity and mortality in the premature neonatal population.

Fetal Brain Abnormalities Following Laser Surgery for Twin‐to‐Twin Transfusion Syndrome: Imaging Patterns and Evolution

Prenatal Diagnosis, EarlyView.
ABSTRACT Introduction Severe brain injury has been reported following fetoscopic laser ablation (FLA) for twin‐to‐twin transfusion syndrome (TTTS), but imaging patterns and temporal evolution remain poorly defined. This study aimed to characterize the progression of severe brain injury after FLA. Methods We conducted a retrospective case series of TTTS

Synthesis of transthyretin by the ependymal cells of the subcommissural organ

Cell and Tissue Research, 2005
Transthyretin (TTR) is a protein involved in the transport of thyroid hormones in blood and cerebrospinal fluid (CSF). The only known source of brain-produced TTR is the choroid plexus. In the present investigation, we have identified the subcommissural organ (SCO) as a new source of brain TTR.

Organized Neurogenic-Niche-Like Pinwheel Structures Discovered in Spinal Cord Tissue-Derived Neurospheres

Frontiers in Cell and Developmental Biology, 2019
The neurogenic niche of the subventricular zone (SVZ) in adult brain tissue takes the form of a pinwheel-like cytoarchitectural structure, with mono-ciliated astrocytes displaying neural stem cell (NSC) characteristics present in the core surrounded by ...

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Brain viral reservoir seeding and neurological metabolic dysregulation in early‐life immunodeficiency virus infection

Brain Pathology, EarlyView.
Brain viral reservoirs were undetectable in neonatal SIV during the first 3 days post infection; antiretroviral therapy (ART) at 3 dpi prevented brain reservoir seeding and normalized metabolic function, highlighting the necessity of very early treatment to protect the developing CNS.

Molecular Classification of Ependymal Tumors across All CNS Compartments, Histopathological Grades, and Age Groups [PDF]

, 2015
Ependymal tumors across age groups are currently classified and graded solely by histopathology. It is, however, commonly accepted that this classification scheme has limited clinical utility based on its lack of reproducibility in predicting patients ...
