α5GABA < sub > A < /sub > receptor: A potential therapeutic target for perioperative neurocognitive disorders, a review of preclinical studies
Brain Res Bull. 2023 Nov 18;205:110821. doi: 10.1016/j.brainresbull.2023.110821. Online ahead of print.ABSTRACTPerioperative neurocognitive disorders (PND) are a common complication in elderly patients following surgery, which not only prolongs the recovery period but also affects their future quality of life and imposes a significant burden on their family and society. Multiple factors, including aging, vulnerability, anesthetic drugs, cerebral oxygen desaturation, and severe pain, have been associated with PND. Unfortunately, no effective drug is currently available to prevent PND. α5 γ-aminobutyric acid subtype A (α5...

The effects of prolyl hydroxylase inhibition during and post, hypoxia, oxygen glucose deprivation and oxidative stress, in isolated rat hippocampal slices
Brain Res Bull. 2023 Nov 18:110822. doi: 10.1016/j.brainresbull.2023.110822. Online ahead of print.ABSTRACTThe contributions of hypoxia and oxidative stress to the pathophysiology of acute ischemic stroke are well established and can lead to disruptions in synaptic signaling. Hypoxia and oxidative stress lead to the neurotoxic overproduction of reactive oxygen species (ROS) and the stabilization of hypoxia inducible factors (HIF). Compounds such as prolyl-4-hydroxylase domain enzyme inhibitors (PHDIs) have been shown to have a preconditioning and neuroprotective effect against ischemic insults such as hypoxia, anoxia, oxyg...

The relationship between TGF- β1 and cognitive function in the brain
Brain Res Bull. 2023 Nov 17;205:110820. doi: 10.1016/j.brainresbull.2023.110820. Online ahead of print.ABSTRACTTransforming growth factor-β1 (TGF-β1), a multifunctional cytokine, plays a pivotal role in synaptic formation, plasticity, and neurovascular unit regulation. This review highlights TGF-β1's potential impact on cognitive function, particularly in the context of neurodegenerative disorders. However, despite the growing body of evidence, a comprehensive understanding of TGF-β1's precise role remains elusive. Further research is essential to unravel the complex mechanisms through which TGF-β1 influences cognitiv...

Symmetry differences of structural connectivity in multiple sclerosis and healthy state
Brain Res Bull. 2023 Nov 14;205:110816. doi: 10.1016/j.brainresbull.2023.110816. Online ahead of print.ABSTRACTFocal and diffuse cerebral damages occur in Multiple Sclerosis (MS) that promotes profound shifts in local and global structural connectivity parameters, mainly derived from diffusion tensor imaging. Most of the reconstruction analyses have applied conventional tracking algorithms largely based on the controversial streamline count. For a more credible explanation of the diffusion MRI signal, we used convex optimization modeling for the microstructure-informed tractography2 (COMMIT2) framework. All multi-shell dif...

Structural abnormalities in the Fronto-Parietal Network: Linking white matter integrity to sustained attention deficits in Schizophrenia
Brain Res Bull. 2023 Nov 14;205:110818. doi: 10.1016/j.brainresbull.2023.110818. Online ahead of print.ABSTRACTSchizophrenia is associated with a range of cognitive deficits, among which impairments in sustained attention are particularly significant. Previous research has investigated functional changes in the fronto-parietal network (FPN) related to attentional control in schizophrenia. However, the role of structural connectivity within the FPN in sustained attention deficits remains under-explored. Utilizing diffusion tensor imaging (DTI), this study investigated white matter integrity in 75 participants, comprising 37...

Feasibility of brain age predictions from clinical T1-weighted MRIs
Brain Res Bull. 2023 Nov 10;205:110811. doi: 10.1016/j.brainresbull.2023.110811. Online ahead of print.ABSTRACTAn individual's brain predicted age minus chronological age (brain-PAD) obtained from MRIs could become a biomarker of disease in research studies. However, brain age reports from clinical MRIs are scant despite the rich clinical information hospitals provide. Since clinical MRI protocols are meant for specific clinical purposes, performance of brain age predictions on clinical data need to be tested. We explored the feasibility of using DeepBrainNet, a deep network previously trained on research-oriented MRIs, to...
