Mapping tissue microstructure of brain white matter in vivo in health and disease using diffusion MRI [PDF]

open access: yesImaging Neuroscience, 2, 1-17, 2024, 2023
Diffusion magnetic resonance imaging offers unique in vivo sensitivity to tissue microstructure in brain white matter, which undergoes significant changes during development and is compromised in virtually every neurological disorder. Yet, the challenge is to develop biomarkers that are specific to micrometer-scale cellular features in a human MRI scan

Update on the multimodal pathophysiological dataset of gradual cerebral ischemia in a cohort of juvenile pigs: auditory, sensory and high-frequency sensory evoked potentials [PDF]

open access: yes, 2021
We expand from a spontaneous to an evoked potentials (EP) data set of brain electrical activities as electrocorticogram (ECoG) and electrothalamogram (EThG) in juvenile pig under various sedation, ischemia and recovery states. This EP data set includes three stimulation paradigms: auditory (AEP, 40 and 2000 Hz), sensory (SEP, left and right maxillary ...

The protective effect of M40401, a superoxide dismutase mimetic, on post-ischemic brain damage in Mongolian gerbils [PDF]

open access: yes, 2003
BACKGROUND: Overproduction of free radical species has been shown to occur in brain tissues after ischemia-reperfusion injury. However, most of free radical scavengers known to antagonize oxidative damage (e.g. superoxide dismutase, catalase), are unable

CNS-border associated macrophages respond to acute ischemic stroke attracting granulocytes and promoting vascular leakage

open access: yesActa Neuropathologica Communications, 2018
The central nervous system (CNS) contains several types of immune cells located in specific anatomic compartments. Macrophages reside at the CNS borders surrounding the brain vessels, in leptomeningeal spaces and the choroid plexus, where they interact ...

Linoleic acid participates in the response to ischemic brain injury through oxidized metabolites that regulate neurotransmission. [PDF]

open access: yes, 2017
Linoleic acid (LA; 18:2 n-6), the most abundant polyunsaturated fatty acid in the US diet, is a precursor to oxidized metabolites that have unknown roles in the brain.

Autophagy in brain ischemia

open access: yesPostępy Higieny i Medycyny Doświadczalnej, 2011
Autophagy is an intracellular process of macromolecule and organelle degradation, which plays an important role both in maintaining homeostasis and in responding to various harmful stimuli. Recent studies clearly indicate upregulation of autophagy in neurons challenged with brain ischemia. In this paper we present biosynthesis of autophagosomes as well

Protective Effect of Adenosine A2B Receptor Agonist, BAY60-6583, Against Transient Focal Brain Ischemia in Rat

open access: yesFrontiers in Pharmacology, 2021
Cerebral ischemia is a multifactorial pathology characterized first by an acute injury, due to excitotoxicity, followed by a secondary brain injury that develops hours to days after ischemia.

Analysis of the Effect of Atherosclerosis with the Changes of Hematocrit: A Computational Study on the Hemodynamics of Carotid Artery [PDF]

open access: yes2020 2nd International Conference on Advanced Information and Communication Technology (ICAICT) (pp. 336-341). IEEE, 2021
Atherosclerosis is a state wherein plaque (fat, cholesterol, and different substances) develops inside the veins that in the end prompts carotid artery stenosis which is a phase of narrowing in the huge courses situated on either side of the neck that convey blood to the brain, face, and head.

Neuroprotective efficacy of nimesulide against hippocampal neuronal damage following transient forebrain ischemia [PDF]

open access: yes, 2002
Cyclooxygenase-2 is involved in the inflammatory component of the ischemic cascade, playing an important role in the delayed progression of the brain damage.

Metabolism of biogenic amines in acute cerebral ischemia: Influence of systemic hyperglycemia [PDF]

open access: yesActa Veterinaria, 2012
Dopamine, norepinephrine and serotonin are biogenic amines which are transmitters of the central nervous system. The effects of ischemia on the brain parenchyma depends on many factors, such is the mechanism of blood flow interruption, velocity of the
