Decoding ruminative reflection in healthy individuals: The role of triple network connectivity.

Ruminative reflection has been linked to enhanced executive control in processing internally represented emotional information, suggesting it may serve as an adaptive strategy for emotion regulation. Investigating the neural substrates of reflection can deepen our understanding of its adaptive properties. This study used network-based statistic (NBS)-Predict methodology to identify resting state functional connectivity (FC)-based predictors of ruminative reflection in a healthy sample.

Assessing pain in multiple sclerosis: Test-retest reliability of patient-reported outcome measures and accuracy of screening tools.

Background: Pain is a common symptom of multiple sclerosis (MS). The reliability of outcome measures for pain and the accuracy of screening tools are essential for treatment purposes.

Objectives: This study investigated the test-retest reliability of Neuropathic Pain Scale (NPS), Neuropathic Pain Symptom Inventory (NPSI), Brief Pain Inventory-Short Form (BPI-SF), Nordic Musculoskeletal Questionnaire (NMQ), Douleur Neuropathique 4 (DN4), and painDETECT, and the accuracy of DN4 and painDETECT.

Syntalos: a software for precise synchronization of simultaneous multi-modal data acquisition and closed-loop interventions.

Complex experimental protocols often require multi-modal data acquisition with precisely aligned timing, as well as state- and behavior-dependent interventions. Tailored solutions are mostly restricted to individual experimental setups and lack flexibility and interoperability. We present an open-source, Linux-based integrated software solution, called 'Syntalos', for simultaneous acquisition and synchronization of data from an arbitrary number of sources, including multi-channel electrophysiological recordings and different live imaging devices, as well as closed-loop, real-time interventions with different actuators.

EARLY SURGERY IN RARE KNEE HETEROTOPIC OSSIFICATION LEADS TO SUCCESSFUL FUNCTIONAL OUTCOME: A CASE REPORT.

Background: Heterotopic ossification is a common complication after joint replacement surgery, such as hip or knee arthroplasty. In the intensive care unit, it is most commonly associated with traumatic brain injury or spinal cord injury. To prevent recurrence, surgical resection of heterotopic ossification is recommended once the ectopic bone has fully matured, which is estimated to occur after at least 12 months.

Establishing In-vivo brain microdialysis for comparing concentrations of a variety of cortical neurotransmitters in the awake rhesus macaque between different cognitive states.

Background: Neuronal activity is modulated by behavior and cognitive processes. The combination of several neurotransmitter systems, acting directly or indirectly on specific populations of neurons, underlie such modulations. Most studies with non-human primates (NHPs) fail to capture this complexity, partly due to the lack of adequate methods for reliably and simultaneously measuring a broad spectrum of neurotransmitters while the animal engages in behavioral tasks.

The impact of labeling automotive AI as trustworthy or reliable on user evaluation and technology acceptance.

This study explores whether labeling AI as either "trustworthy" or "reliable" influences user perceptions and acceptance of automotive AI technologies. Utilizing a one-way between-subjects design, the research presented online participants (N = 478) with a text presenting guidelines for either trustworthy or reliable AI, before asking them to evaluate 3 vignette scenarios and fill in a modified version of the Technology Acceptance Model which covers different variables, such as perceived ease of use, human-like trust, and overall attitude. While labeling AI as "trustworthy" did not significantly influence people's judgements on specific scenarios, it increased perceived ease of use and human-like trust, namely benevolence, suggesting a facilitating influence on usability and an anthropomorphic effect on user perceptions.

Virtual reality for multiple sclerosis rehabilitation.

Background: Multiple sclerosis (MS) is the most common neurological disease in young adults. Virtual reality (VR) offers a promising rehabilitation tool by providing controllable, personalised environments for safe, adaptable and engaging training. Virtual reality can be tailored to patients' motor and cognitive skills, enhancing motivation through exciting scenarios and feedback.

Engaging dystonia networks with subthalamic stimulation.

Deep brain stimulation is an efficacious treatment for dystonia. While the internal pallidum serves as the primary target, recently, stimulation of the subthalamic nucleus (STN) has been investigated. However, optimal targeting within this structure and its surroundings have not been studied in depth.

Bichromatic Splicing Detector Allows Quantification of and Splicing Isoforms in Single Cells by Fluorescent Live-Cell Imaging.

Thyroid hormone receptor alpha (THR) is a nuclear hormone receptor that binds triiodothyronine (T3) and acts as an important transcription factor in development, metabolism, and reproduction. The coding gene, , has two major splicing isoforms in mammals, and , which encode THR1 and THR1, respectively. The better characterized isoform, THR1, is a transcriptional stimulator of genes involved in cell metabolism and growth.

Baseline gray matter volume associates with working memory performance after prefrontal transcranial direct current stimulation.

Working memory is crucial for daily life and is often impaired in neuropsychiatric conditions. Attempts to enhance it using transcranial direct current stimulation (tDCS) have shown mixed results, possibly due to large inter-individual variability. This study assessed whether baseline regional brain volume was associated with working memory performance following tDCS.

Speed-dependent changes in the arm swing during independent walking in individuals after stroke.

Background: Increasing one's walking speed is an important goal in post-stroke gait rehabilitation. Insufficient arm swing in people post-stroke might limit their ability to propel the body forward and increase walking speed.

Purpose: To investigate the speed-dependent changes (and their contributing factors) in the arm swing of persons post-stroke.

Does rehabilitation improve work participation in patients with chronic spinal pain after spinal surgery: a systematic review.

Objective: Patients with therapy-refractory chronic spinal pain after spinal surgery experience increased disability, resulting in substantial loss of employment and consequently lower quality of life. Despite findings that rehabilitation improves socio-economic outcomes in other chronic pain conditions, evidence for patients with chronic spinal pain after spinal surgery is limited. A systematic review was conducted to provide an overview of rehabilitation interventions and their effectiveness to improve work participation for patients with chronic spinal pain after spinal surgery.

The relationship between mitochondrial health, telomerase activity and longitudinal telomere attrition, considering the role of chronic stress.

Telomere attrition is a hallmark of biological aging, contributing to cellular replicative senescence. However, few studies have examined the determinants of telomere attrition in vivo in humans. Mitochondrial Health Index (MHI), a composite marker integrating mitochondrial energy-transformation capacity and content, may be one important mediator of telomere attrition, as it could impact telomerase activity, a direct regulator of telomere maintenance.

Longitudinal network changes and phenoconversion risk in isolated REM sleep behavior disorder.

Isolated rapid eye movement sleep behavior disorder is a prodrome of α-synucleinopathies. Using positron emission tomography, we assessed changes in Parkinson's disease-related motor and cognitive metabolic networks and caudate/putamen dopaminergic input in a 4-year longitudinal imaging study of 13 male subjects with this disorder. We also correlated times to phenoconversion with baseline network expression in an independent validation sample.

Multiple Sclerosis: Glial Cell Diversity in Time and Space.

Multiple sclerosis (MS) is the most prevalent human inflammatory disease of the central nervous system with demyelination and glial scar formation as pathological hallmarks. Glial cells are key drivers of lesion progression in MS with roles in both tissue damage and repair depending on the surrounding microenvironment and the functional state of the individual glial subtype. In this review, we describe recent developments in the context of glial cell diversity in MS summarizing key findings with respect to pathological and maladaptive functions related to disease-associated glial subtypes.

The cerebellum is involved in implicit motor sequence learning.

Background: Implicit motor sequence learning (IMSL) is a cognitive function that allows us to execute multiple movements in a specific sequential order and plays a crucial role in our daily functional activities. Although the role of the basal ganglia network in IMSL is well-established, the exact involvement of the cerebellar network is less clear.

Aim: Here, we aimed to address this issue by investigating the effects of cerebellar transcranial direct-current stimulation (tDCS) on IMSL.

Top-down and emotional attention in blind and sighted individuals.

There is evidence that congenitally blind individuals possess superior auditory perceptual skills compared to sighted people. However, relatively little is known about the auditory-specific cortical correlates of spatial attention in the blind and how task-irrelevant emotional stimulus features could further modulate such neural processes. This study tested blind and sighted participants in a challenging auditory discrimination task.

Cancer memory as a mechanism to establish malignancy.

Cancers during oncogenic progression hold information in epigenetic memory which allows flexible encoding of malignant phenotypes and more rapid reaction to the environment when compared to purely mutation-based clonal evolution mechanisms. Cancer memory describes a proposed mechanism by which complex information such as metastasis phenotypes, therapy resistance and interaction patterns with the tumor environment might be encoded at multiple levels via mechanisms used in memory formation in the brain and immune system (e.g.

Exploring the Effects of Prefrontal Transcranial Direct Current Stimulation on Brain Metabolites: A Concurrent tDCS-MRS Study.

Transcranial Direct Current Stimulation (tDCS) is a non-invasive brain stimulation technique used to modulates cortical brain activity. However, its effects on brain metabolites within the dorsolateral prefrontal cortex (DLPFC), a crucial area targeted for brain stimulation in mental disorders, remain unclear. This study aimed to investigate whether prefrontal tDCS over the left and right DLPFC modulates levels of key metabolites, including gamma-aminobutyric acid (GABA), glutamate (Glu), glutamine/glutamate (Glx), N-acetylaspartate (NAA), near to the target region and to explore potential sex-specific effects on these metabolite concentrations.

Virtual Reality to Improve Sleep Quality in Patients Suffering from Painful Diabetic Polyneuropathy: A Proof of Concept Study.

: Sleep disturbance is often observed in the context of chronic pain. We hypothesize that, by providing an immersive Virtual Reality (VR) experience with a serious game to chronic pain patients an hour before bedtime, attention can be diverted from the pain condition, consequently leading to improved sleep quality. The aim is to evaluate the efficacy of VR compared to usual care in reducing the number of awakenings during the night and increasing sleep efficiency in patients suffering from painful diabetic polyneuropathy (PDPN).

A critical role of action-related functional networks in Gilles de la Tourette syndrome.

Gilles de la Tourette Syndrome (GTS) is a chronic tic disorder, characterized by unwanted motor actions and vocalizations. While brain stimulation techniques show promise in reducing tic severity, optimal target networks are not well-defined. Here, we leverage datasets from two independent deep brain stimulation (DBS) cohorts and a cohort of tic-inducing lesions to infer critical networks for treatment and occurrence of tics by mapping stimulation sites and lesions to a functional connectome derived from 1,000 healthy participants.

Ferroptosis driven by nanoparticles for tackling glioblastoma.

Glioblastoma (GBM) is the most aggressive, malignant, and drug-resistant brain tumor. There are no effective treatment options for GBM, which usually leads to relapses that cause patients to die a few months later. Ferroptosis, a newly discovered mechanism of regulated cell death, has been identified as a tumor suppressor in solid tumors and represents an alternative to apoptosis resistance.

Alpha-synuclein knockout impairs melanoma development and alters DNA damage repair in the TG3 mouse model in a sex-dependent manner.

Strong evidence suggests links between Parkinson's Disease (PD) and melanoma, as studies have found that people with PD are at an increased risk of developing melanoma and those with melanoma are at increased risk of developing PD. Although these clinical associations are well-established, the cellular and molecular pathways linking these diseases are poorly understood. Recent studies have found a previously unrecognized role for the neurodegeneration-associated protein alpha-synuclein (αSyn) in melanoma; the overexpression of αSyn promotes melanoma cell proliferation and metastasis.

Mass-Guided Single-Cell MALDI Imaging of Low-Mass Metabolites Reveals Cellular Activation Markers.

Single-cell MALDI mass spectrometry imaging (MSI) of lipids and metabolites >200 Da has recently come to the forefront of biomedical research and chemical biology. However, cell-targeting and metabolome-preserving methods for analysis of low mass, hydrophilic metabolites (<200 Da) in large cell populations are lacking. Here, the PRISM-MS (PRescan Imaging for Small Molecule - Mass Spectrometry) mass-guided MSI workflow is presented, which enables space-efficient single cell lipid and metabolite analysis.

Assessment of Dementia in Minority Ethnic Groups in Europe: A 14-Year Follow-Up Survey.

Objectives: There is no European consensus on good clinical practice for timely diagnosis and culturally appropriate care of people with dementia from minority ethnic groups. Despite significant advances in culture-sensitive dementia diagnostics, little is known about how this has been implemented in clinical practice. The aims of this follow-up survey were to explore current practices for assessing dementia in patients from minority ethnic groups in Europe and to determine whether barriers in access to specialized dementia services have changed during the last 14 years.
