Article Abstract
Hydrocephalus is one of the most common neurological diseases, characterized by abnormal excessive accumulation of cerebrospinal fluid (CSF) in the ventricular system. Its pathophysiological mechanism is believed to be related to the imbalance of CSF circulation and homeostasis. As the main source of CSF secretion, the choroid plexus is closely related to hydrocephalus. The choroid plexus is a specialized vascularized tissue located within the cerebral ventricles. It has multiple physiological functions including regulating CSF, immune response, endocrine metabolism, etc. Strategies that reduce choroid plexus CSF secretion have been shown to be effective in the treatment of hydrocephalus. However, the role of other physiological functions of the choroid plexus in hydrocephalus is still unclear. Recent studies on the choroid plexus and the blood-CSF barrier have deepened our understanding of the structure and function of the choroid plexus. The idea of targeting the choroid plexus to treat hydrocephalus has spawned many branches: choroid plexus epithelial cells, choroid plexus immune cells, choroid plexus peptides, and choroid plexus cilia, etc. This review introduces the basic structure and function of the choroid plexus, summarizes their changes in hydrocephalus, and analyzes the possibility of the choroid plexus as a therapeutic target for hydrocephalus.

West Nile fever is a zoonotic arboviral disease caused by the West Nile Virus (WNV), responsible for deaths in humans, mammals, and birds with associated neurological manifestations. All previous investigations of WNV Brazil were based primarily on serological and molecular analyses and in humans, equids, and birds in the northern and southeastern regions of the country. This study describes the pathological and molecular findings observed in a mule, from the state of Paraná, southern Brazil, that died during an outbreak involving equids with clinical manifestations of a neurological disease.

Traditionally, clinical devices are designed, tested and improved through lengthy and expensive laboratory experiments and clinical trials [1]. More recently, computational methods have allowed for rapid testing, speeding up the design process and enabling far more complete searches of design space. While computational models cannot fully capture the complexities of biological systems, they provide valuable insights into crucial underlying mechanisms, such as the effects of fluid-structure interactions (FSIs).

Alzheimer's disease (AD) is the most common, complex, and untreatable form of dementia which is characterized by severe cognitive, motor, neuropsychiatric, and behavioural impairments. These symptoms severely reduce the quality of life for patients and impose a significant burden on caregivers. The existing therapies offer only symptomatic relief without addressing the underlying silent pathological progression.

Introduction: The aim of this study is to investigate, using magnetic resonance imaging (MRI), the optic nerve diameter, morphometric characteristics of the optic chiasm (OC), volumes of the lateral, third, and fourth ventricles, as well as the volumes of the corpus callosum (CC) and choroid plexus (CP) in children with autism spectrum disorder (ASD), and to compare these findings with those of a typically developing (TD) control group. Additionally, the study seeks to evaluate the impact of these neuroanatomical parameters on autism symptom severity and sensory sensitivity.
Methods: This study included 111 children with ASD and 143 TD control children, aged between 5 and 13 years.
