Background: Although it has been noticed that depressed patients show differences in processing emotions, the precise neural modulation mechanisms of positive and negative emotions remain elusive. FMRI is a cutting-edge medical imaging technology renowned for its high spatial resolution and dynamic temporal information, making it particularly suitable for the neural dynamics of depression research.

Methods: To address this gap, our study firstly leveraged fMRI to delineate activated regions associated with positive and negative emotions in healthy individuals, resulting in the creation of the positive emotion atlas (PEA) and the negative emotion atlas (NEA).

Oromandibular dystonia (OMD) is a focal dystonia characterized by contractions of the masticatory, lingual, and other muscles of the stomatognathic system. We conducted a systematic review and meta-analysis to elucidate the impact and safety of botulinum toxin in OMD. The eligibility criteria were full-length original articles that provided data evaluating the efficacy and adverse effects of onabotulinumtoxinA injections in patients with OMD.

Objectives: Blood pressure (BP) management is challenging in patients with acute ischemic supratentorial stroke undergoing recanalization therapy due to the lack of established guidelines. Assessing dynamic cerebral autoregulation (dCA) may address this need, as it is a bedside technique that evaluates the transfer function phase in the very low-frequency (VLF) range (0.02-0.

Harsh acid oxidation of activated charcoal transforms an insoluble carbon-rich source into water-soluble, disc structures of graphene decorated with multiple oxygen-containing functionalities. We term these pleiotropic nano-enzymes as "pleozymes". A broad redox potential spans many crucial redox reactions including the oxidation of hydrogen sulfide (HS) to polysulfides and thiosulfate, dismutation of the superoxide radical (O*), and oxidation of NADH to NAD.

Ischemic stroke is a major cause of mortality and disability and has become a significant public health concern among women. Overall, women have more ischemic stroke events than men, in part due to their longer life span, and also suffer from more severe stroke-related disabilities compared to men. Women are also more likely than men to present with atypical non-focal neurological symptoms, potentially leading to delayed diagnosis and treatment.

Aims: Epidemiological studies have consistently established a positive association between periodontal disease (PD) and cardiovascular disease (CVD). However, large-scale investigations exploring the impact of changes in PD status on CVD risk are scarce. This study aimed to investigate the association between the dynamics in PD and the risk of incident CVD in a nationally representative population.

Determining the Optimal Age for Extracranial-Intracranial Bypass Surgery: A Post Hoc Analysis of the CMOSS Randomized Trial.

Stroke

December 2024

Department of Neurosurgery and Interventional Neuroradiology, Xuanwu Hospital, China International Neuroscience Institute, Capital Medical University, National Center for Neurological Disorders, Beijing, China. (L.J.).

Background: Previous trials have failed to demonstrate the benefits of extracranial-intracranial (EC-IC) bypass surgery for patients with carotid or middle cerebral artery occlusion. However, little evidence has focused on the effect of age on prognosis. This study aimed to explore whether EC-IC bypass surgery can provide greater benefits than medical therapy alone in specific age groups.

Autoimmune nodopathy (AN) is a rare immune-mediated neuropathy characterized by autoantibodies against nodal or paranodal proteins. Patients with AN generally respond poorly to immunoglobulin therapy, and as a newly defined condition, there are currently no established treatment guidelines. Although rituximab shows potential as a therapeutic option, its high cost, limited availability, and the need for infusion monitoring hinder its use as a first-line treatment in many countries.

Background: The prevalence of idiopathic intracranial hypertension (IIH) is rising with the global obesity epidemic. Carbonic anhydrase inhibitors (CAIs), such as acetazolamide, have been shown to be effective in IIH but can also lead to kidney stone formation. This study evaluates the risk of kidney stone development in patients with IIH treated with CAIs.

Altered Nigral Amide Proton Transfer Imaging Signal Concordant With Motor Asymmetry in Parkinson's Disease: A Multipool CEST MRI Study.

NMR Biomed

February 2025

Department of Radiology, Beijing Hospital, National Center of Gerontology, Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, Beijing, China.

Asymmetry is a natural characteristic of Parkinson's disease (PD), which can be used to distinguish PD from atypical parkinsonism. Chemical exchange saturation transfer (CEST) has demonstrated value in reflecting the subtle changes related to neuron loss and abnormal protein accumulation in PD but has not been used to investigate asymmetry in PD. This study aimed to examine asymmetrical changes in the mesencephalic nucleus of PD patients with motor asymmetry using four-pool CEST analysis and to explore the relationship between imaging asymmetry and motor asymmetry.

Peripheral nerve injury poses a significant challenge to the nervous system's regenerative capacity. We previously described a novel approach to construct a chitosan/silk fibroin nerve graft with skin-derived precursor-induced Schwann cells (SKP-SCs). This graft has been shown to promote sciatic nerve regeneration and functional restoration to a level comparable to that achieved by autologous nerve grafts, as evidenced by behavioral, histological, and electrophysiological assessments.

The triggering receptor expressed on myeloid cells 2 (TREM2) is a transmembrane protein found in microglia within the brain, and its soluble form (sTREM2) has been shown to reduce amyloid deposition. Whether elevated TREM2-mediated microglial activity decreases the risk of Alzheimer's disease (AD) is unclear. The aim of this study was to assess whether high cerebrospinal fluid (CSF) levels of sTREM2 attenuate the risk of APOE ε4-associated amyloid pathology.
