Impact of physiological and neuropsychological function on quality of life in traumatic brain injury patients.

Traumatic Brain Injury (TBI) leads to neuropsychological and social impairments, affecting quality of life (QoL). This study examines how heart rate variability (HRV) and neuropsychological functions under different cognitive task conditions influence TBI patients' QoL. The study adopted 20 healthy and 11 TBI participants.

Environmental enrichment promotes functional recovery from stroke via enhancing neuroplasticity through the action of -HB.

Stroke is a leading cause of adult disability worldwide, unfortunately, no drugs are clinically available to promote functional recovery after stroke. Although animal environmental enrichment is a recognized paradigm for promoting stroke repair, elusive mechanisms hinder its clinical translation. Here, we show that β-hydroxybutyrate (β-HB) level in the peri-infarct cortex is upregulated after environmental enrichment (EE) exposure.

Astrocytic BEST1 can serve as a target for functional recovery after ischemic stroke.

Solid evidence from animal experiments supported the concept of peri-infarct tonic inhibition. Related drug targets have the potential to be translated for clinical stroke treatment. Recently, we reported the contribution of neuronal bestrophin-1 (BEST1)-mediated glutamate release to acute ischemic damage exacerbation in rodents.

Enhancing recanalization success: Thrombectomy plus stent angioplasty by coaxial balloon technique for acute ischemic stroke with tandem occlusions.

Recanalizing acute ischemic stroke with carotid tandem occlusion (CTO) is technically challenging because distal embolic migration during revascularization can significantly influence outcomes. In this study, we aimed to introduce our coaxial balloon technique using a balloon-guiding catheter (BCG), angioplasty catheter, and aspiration catheter sequentially to prevent thrombus migration to a new vascular territory. We used this technique for six patients with CTO.

Intrinsic 77 K Phosphorescence Characteristics and Computational Modeling of Ru(II)-(Bidentate Cyclometalated-Aromatic Ligand) Chromophores: Their Relatively Low Nonradiative Rate Constants Originating from Low Spin-Orbit Coupling Driven Vibronic Coupling Amplitudes between Emitting and Ground States.

We investigated the photoinduced relaxation of Kasha-type emitting ruthenium-(bidentate cyclometalated aromatic ligand), Ru-CM, chromophores of [Ru(pzpy)(CM)] ions (CM = 1-phenylisoquinoline, 2,3-diphenylpyrazine, and 1,4-diazatriphenylene and pzpy = 2-pyrazol-1-yl-pyridine). This is the first report of the phosphorescence behavior of pure Ru-(bidentate CM) chromophores. The 77 K photoinduced relaxation characteristics of phosphorescence chromophores showed emission quantum yields higher than those of reference Ru-bpy (bpy = 2,2'-bipyridine) chromophores in the emission region of 670-900 nm.

Disrupting stroke-induced GAT-1-syntaxin1A interaction promotes functional recovery after stroke.

Although stroke is a frequent cause of permanent disability, our ability to promote stroke recovery is limited. Here, we design a small-molecule stroke recovery promoting agent that works by dissociating γ-aminobutyric acid (GABA) transporter 1 (GAT-1) from syntaxin1A (Synt1A), a soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) protein. Stroke induces an increase in GAT-1-Synt1A interaction in the subacute phase, a critical period for functional recovery.

Functional reconstruction of the impaired cortex and motor function by hMGEOs transplantation in stroke.

Stroke is the leading cause of death and long-term disability worldwide. But treatments are not available to promote functional recovery, and efficient therapies need to be investigated. Stem cell-based therapies hold great promise as potential technologies to restore function in brain disorders.

Cerebral organoids transplantation repairs infarcted cortex and restores impaired function after stroke.

Stroke usually causes prolonged or lifelong disability, owing to the permanent loss of infarcted tissue. Although a variety of stem cell transplantation has been explored to improve neuronal defect behavior by enhancing neuroplasticity, it remains unknown whether the infarcted tissue can be reconstructed. We here cultured human cerebral organoids derived from human pluripotent stem cells (hPSCs) and transplanted them into the junction of the infarct core and the peri-infarct zone of NOD-SCID mice subjected to stroke.

Ketone bodies promote stroke recovery via GAT-1-dependent cortical network remodeling.

Stroke is a leading cause of adult disability worldwide, and better drugs are needed to promote functional recovery after stroke. Growing evidence suggests the critical role of network excitability during the repair phase for stroke recovery. Here, we show that β-hydroxybutyrate (β-HB), an essential ketone body (KB) component, is positively correlated with improved outcomes in patients with stroke and promotes functional recovery in rodents with stroke during the repair phase.

Noncontrast MRI in assessing venous reflux of legs using QFlow analysis and radial basis function neural network technique.

Since venous reflux is difficult to quantify, triggered angiography non-contrast-enhanced (TRANCE)-magnetic resonance imaging (MRI) is a novel tool for objectively evaluating venous diseases in the lower extremities without using contrast media. This study included 26 pre-intervention patients with superficial venous reflux in the lower extremities and 15 healthy volunteers. The quantitative flow (QFlow) analyzed the phase shift information from the pixels within the region of interest from MRI.

Enhanced AMPAR-dependent synaptic transmission by S-nitrosylation in the vmPFC contributes to chronic inflammatory pain-induced persistent anxiety in mice.

Chronic pain patients often have anxiety disorders, and some of them suffer from anxiety even after analgesic administration. In this study, we investigated the role of AMPAR-mediated synaptic transmission in the ventromedial prefrontal cortex (vmPFC) in chronic pain-induced persistent anxiety in mice and explored potential drug targets. Chronic inflammatory pain was induced in mice by bilateral injection of complete Freund's adjuvant (CFA) into the planta of the hind paws; anxiety-like behaviours were assessed with behavioural tests; S-nitrosylation and AMPAR-mediated synaptic transmission were examined using biochemical assays and electrophysiological recordings, respectively.
