Metastasis to the central nervous system (CNS) is an obstacle for leukemia treatment, the mechanisms of which remain to be elucidated. VEGF-A and VEGF-C are suspected to participate in this process. Paired of cerebrospinal fluid (CSF) and serum samples were collected from leukemia and control cases. Levels of VEGF-A and VEGF-C in both CSF (VEGF-ACSF, VEGF-CCSF) and serum (VEGF-ASerum, VEGF-CSerum) were detected by ELISA. Our data show that higher levels of VEGF-ACSF are closely related to CNS leukemia (CNSL), and VEGF-ACSF may be a better predictor than the other risk factors elucidating the pathogenesis and development of CNSL.

Network analysis of intergenerational transmission of psychopathological symptom among adolescents: A cross-sectional study.
J Fam Psychol
January 2025
Department of Psychiatry, Renmin Hospital of Wuhan University.
The intergenerational transmission of psychopathology has been well documented, but limited studies have examined the link at the symptomatic level accounting for these associations. This study aimed to identify the central symptoms that bridge adolescents and parental psychopathological symptoms and the specific symptom pathways by using a novel network approach. From September to October 2021, a cross-sectional study was conducted in Wuhan, China.

Background: Glucose transporter 1 deficiency syndrome (Glut1DS) was initially reported by De Vivo and colleagues in 1991. This disease arises from mutations in the SLC2A1 and presents with a broad clinical spectrum. It is a treatable neuro-metabolic condition, where prompt diagnosis and initiation of ketogenic dietary therapy can markedly enhance the prognosis.

In clinics, physical injuries to the spinal cord cause a temporary motor areflexia below lesion, known as spinal shock. This topic is still underexplored due to the lack of preclinical spinal cord injury (SCI) models that do not use anesthesia, which would affect spinal excitability. Our innovative design considered a custom-made micro impactor that provides localized and calibrated strikes to the ventral surface of the thoracic spinal cord of the entire CNS isolated from neonatal rats.

Department of Nutrition, Federal University of Pernambuco, Recife, Brazil.
Objectives: Maternal protein malnutrition alters brain functioning, impairing fetal development. Physical exercise during gestation benefits the fetal organism from maternal adaptive changes that may be neuroprotective. This study evaluated the effect of a low-protein diet associated with maternal voluntary physical activity (VPA) on rats' behavioral and brain electrophysiological parameters in the mother-pup dyad.

Purpose Of Review: To evaluate the role of neuroimmune signalling pathways in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP).
Recent Findings: The sinonasal mucosa is densely infiltrated by immune cells and neuronal structures that share an intimate spatial relationship within tissue compartments. Together, such neuroimmune units play a critical role in airway defence and homeostatic function.
