Peripheral blood presents an available source of cells for both fundamental research and clinical use. In our study, we have evaluated the therapeutic potential of peripheral blood mononuclear cells (PBMCs) excluding the preliminary sorting or mobilization of peripheral blood stem cells. We have evaluated the regenerative potential of PBMCs embedded into a fibrin matrix (FM) in a model of pig spinal cord injury. The distribution of transplanted PBMCs in the injured spinal cord was evaluated; PBMCs were shown to penetrate into the deep layers of the spinal cord and concentrate mainly in the grey matter. The results of the current study revealed an increase in the tissue integrity in the area adjacent to the epicenter of injury and the partially restored conduction along posterior columns of the spinal cord in animals after FM+PBMC application. The multiplex analysis of blood serum and cerebrospinal fluid showed the cytokine imbalance to occur without significantly shifting toward pro-inflammatory or anti-inflammatory cytokine cascades.

Long-term effects of linear versus macrocyclic GBCAs on gene expression in the central nervous system of mice.
Eur Radiol Exp

Laboratory of Molecular Imaging, Department of Radiology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, Jiangsu, China.
Background: We examined chronic gadolinium retention impact on gene expression in the mouse central nervous system (CNS) after injection of linear or macrocyclic gadolinium-based contrast agents (GBCAs).
Methods: From 05/2022 to 07/2023, 36 female mice underwent weekly intraperitoneal injections of gadodiamide (2.5 mmol/kg, linear), gadobutrol (2.
Trigeminal neuralgia as a presentation of high cervical stenosis: a systematic review of the literature.

Department of Neurosurgery, University of Arizona College of Medicine, 1111 Mc Dowell Road, Phoenix, AZ, 85006, USA.
Purpose: An atypical presentation of cervical spondylopathy (CS), trigeminal neuralgia (TN) is attributable to the extension of trigeminal nuclei into the spinal cord and is frequently overlooked, leading to limited discussion with patients regarding potential anterior cervical surgery. Our systematic review assesses the effectiveness of cervical surgery for concurrent trigeminal neuralgia in cases of cervical spondylopathy.
Methods: A systematic review exploring cases of trigeminal neuralgia related to cervical spondylopathy was conducted searching on PubMed, Scopus and Embase databases for article in English.
A multicenter micro-costing analysis of flexible cystoscopic procedures in Korea.
Investig Clin Urol
January 2025
Department of Spinal Neurosurgery, Gangnam Severance Hospital, Seoul, Korea.
Purpose: This study aims to develop and implement an economic evaluation using a micro-costing approach to provide a precise and transparent analysis of the direct costs of cystoscopic procedures in Korean hospitals. The study seeks to identify key cost components and evaluate whether current reimbursement rates accurately reflect these direct costs.
Materials And Methods: Significant variations in cost items were identified across different studies.
Primary Cerebral Lymphoma With Isolated Vitreoretinal and Cerebral Recurrences Without Meningeosis: A Case Report.

Primary central nervous system lymphoma (PCNSL) is a diffuse, large B-cell lymphoma affecting the brain, spinal cord, leptomeninges, or eyes. A patient with a recurrence of a previous PCNSL manifesting as an isolated vitreoretinal disease without central nervous system (CNS) involvement and a second cerebral recurrence without vitreoretinal involvement has not yet been reported. The patient is an 86-year-old man with PCNSL of the left cerebellum diagnosed at the age of 82 years and treated with suboccipital trepanation and resection of the lesion followed by chemotherapy.

Background: Maternal nutrition profoundly influences offspring health, impacting both prenatal and early postnatal development. Previous studies have demonstrated that maternal dietary habits can affect key developmental pathways in the offsprings, including those related to lung function and disease susceptibility. However, the sex-specific impact of a maternal high-salt diet (HSD) on offspring lung injury remains poorly understood.
