Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Ontogeny of Somatostatin Gene Expression in Rat Diencephalon [PDF]

, 1991
Somatostatin gene expression is first detectable, using in situ hybridization, on the 14th fetal day in rat diencephalon. Other structures expressing somatostatin messenger RNA include the anterior basal periventricular nucleus, amygdalo-hippocampal ...

Feasibility and Reproducibility of a Structure‐Guided Deep Learning Model for Automatic Detection of the Standard Sagittal Plane in First‐Trimester Nuchal Translucency Assessment Using 3D Ultrasound

Journal of Ultrasound in Medicine, EarlyView.
Objectives Accurate nuchal translucency (NT) measurement for assessing the risk of fetal genetic abnormalities requires precise acquisition of the mid‐sagittal plane (MSP). However, achieving an appropriate MSP is technically challenging due to anatomical variability and operator dependence inherent in conventional 2‐dimensional (2D) ultrasound.

EE2 and the Fish Brain: Age‐Dependent Impact of 17α‐Ethinylestradiol on Brain Cell Proliferation and Behavior in Sea Bass Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Endocrine‐disrupting chemicals (EDCs), such as 17α‐ethinylestradiol (EE2), have raised concerns about their potential effects on aquatic organisms, particularly during early developmental stages. In this context, the study of behavioral disruption has gained considerable attention, as it may have consequences on individual fitness and ...

WNT signaling affects gene expression in the ventral diencephalon and pituitary gland growth [PDF]

, 2008
We examined the role of WNT signaling in pituitary development by characterizing the pituitary phenotype of three WNT knockout mice and assessing the expression of WNT pathway components.

Non‐Alzheimer Aβ deposits in the human CNS: Implications with hypoxia and related conditions

Brain Pathology, EarlyView.
An Aβ deposit in a non‐Alzheimer's brain from an individual who experienced hypoxia/energy failure. Abstract We recently reported the deposition of Aβ in the frontal cortex of individuals who died of acute coronavirus disease 2019 (COVID‐19), or who did not have COVID‐19 but had respiratory distress, or infants with severe cardiac malformations.

Academic Achievement Test for Anatomy of the Neck: Validity and Reliability Analysis

European Journal of Dental Education, EarlyView.
ABSTRACT Objective Anatomy education remains a fundamental component of medical and dental curricula, and mastering neck anatomy is particularly challenging due to its structural complexity and clinical relevance. Despite its importance, there is a limited number of validated instruments specifically designed to assess academic achievement in neck ...

Human cerebral arterial morphogenesis explored by 3D microscopic imaging of cleared embryos: Bridging the gap between embryonic and adult anatomy

Journal of Anatomy, EarlyView.
We provide a description of human embryonic cerebral arterial development based on whole‐mount immunostaining, tissue clearing, three‐dimensional (3D) light‐sheet microscopy imaging, and anatomically informed virtual segmentation of human embryos. Findings are compared with adult radiological anatomy. We provide a detailed account of the development of
