Potential Mechanism of Venous System for Leukoaraiosis: From post-mortem to in vivo Research.
Abstract BACKGROUND: Leukoaraiosis (LA), widely accepted as a feature of cerebral small vessel disease, significantly increases the incidence of stroke, dementia, and death. Cerebral small artery disease has been considered as one of the main causes of LA. However, since the term "venous collagenosis" (VC) was proposed in an atrophy research in 1995, there have been pathological and neuroimaging studies proving the association between the venous system and LA in aging, Alz-heimer's disease (AD), and Parkinson's disease. SUMMARY: Autopsy studies confirmed that thickening of the lumen wall in venules, which res...

Association of serum retinoic acid with depression in patients with acute ischemic stroke.
This study was aimed to evaluate the relationship between RA levels in serum and post-stroke depression (PSD). A single-center (Chengdu, China) prospective cohort study was conducted on patients with acute ischemic stroke. The RA serum level was measured at admission. The PSD was assessed in the 3-month follow-up. The RA-PSD relationship was evaluated with conditional logistic regression. In total, 239 ischemic stroke cases and 100 healthy controls were included. The median RA serum level in patients with ischemic stroke was 2.45 ng/ml (interquartile range [IQR], 0.72-4.33), lower(P<0.001) than 3.89 ng/ml of those in co...

Beneficial actions of prothymosin alpha-mimetic hexapeptide on central post-stroke pain, reduced social activity, learning-deficit and depression following cerebral ischemia in mice
Publication date: Available online 23 January 2020Source: PeptidesAuthor(s): Keita Sasaki, Sebok Kumar Halder, Hayato Matsunaga, Hiroshi UedaAbstractProthymosin alpha (ProTα)-mimetic hexapeptide (amino acid: NEVDQE, P6Q) inhibits cerebral or retinal ischemia-induced behavioral, electrophysiological and histological damage. P6Q also abolishes cerebral hemorrhage induced by ischemia with tissue plasminogen activator (tPA). In the present study we examined the beneficial effects of P6Q on other post-stroke prognostic psychology-related symptoms, which obstruct the motivation toward physical therapy.

Lactate: More Than Merely a Metabolic Waste Product in the Inner Retina
AbstractThe retina is an extension of the central nervous system and has been considered to be a simplified, more tractable and accessible version of the brain for a variety of neuroscience investigations. The optic nerve displays changes in response to underlying neurodegenerative diseases, such as stroke, multiple sclerosis, and Alzheimer ’s disease, as well as inner retinal neurodegenerative disease, e.g., glaucoma. Neurodegeneration has increasingly been linked to dysfunctional energy metabolism or conditions in which the energy supply does not meet the demand. Likewise, increasing lactate levels have been correlated...

Involvement of regulated necrosis in blinding diseases: Focus on necroptosis and ferroptosis.
Abstract Besides apoptosis, necrosis can also occur in a highly regulated and genetically controlled manner, defined as regulated necrosis, which is characterized by a loss of cell membrane integrity and release of cytoplasmic content. Depending on the involvement of its signal pathway, regulated necrosis can be further classified as necroptosis, ferroptosis, pyroptosis and parthanatos. Numerous studies have demonstrated that regulated necrosis is involved in the pathogenesis of many diseases covering almost all organs including the brain, heart, liver, kidney, intestine, blood vessel, eye and skin, particularly m...

Prevalence of Retinal Emboli and Acute Retinal Artery Occlusion in Acute Ischemic Stroke
In population-based studies asymptomatic retinal emboli occur in .32%-2.9% of people. Retinal artery occlusion (RAO) may occur concurrently with cerebral stroke but the frequency is unknown. No study has examined how commonly retinal emboli occur in the acute stroke population. We aimed to assess the prevalence of retinal emboli and RAO at the time of carotid territory ischemic stroke.

Retinal artery occlusion does not portend an increased risk of stroke
The aim of this study was to determine the subsequent risk of stroke after a diagnosis of retinal artery occlusion (RAO). We hypothesized that the risk would be low and comparable to that of the general population. RAO is relatively rare and often incorrectly diagnosed. We believe our institution is in a unique position to investigate this relationship with both a high-volume eye center and vascular laboratory.

Demonstration of acute retinal ischemia on diffusion weighted magnetic resonance imaging
In this case, we demonstrate the ability of diffusion weighted magnetic resonance imaging to localize retinal ischemia in a patient with acute vision loss. MRI is widely used for the evaluation of acute stroke, but there has only been one other case report showing the ability of DWI to rapidly localize retinal pathology, including central retinal artery occlusion [1]. Central retinal artery occlusion is an ocular emergency presenting with acute, painless loss of vision as a result of retinal ischemia.

Role of Bariatric Surgery in Managing Macrovascular Complications of Obesity-Related Type 2 Diabetes
Reducing the risk of macrovascular events, including myocardial infarction and stroke, is a major goal when treating diabetes. Despite this focus, of the major randomized trials used to support current diabetes guidelines (ACCORD, ADVANCE, UKPDS 33, UKPDS 34, VADT), none showed reductions in macrovascular events when the trial results were first reported. For example, UKPDS is still frequently cited in support of aggressive glucose lowering, yet when the primary outcome data were presented in 1998, the results showed no difference between groups in terms of reducing the risk of all-cause mortality (relative risk [RR], 0.94...

Atrial Fibrillation: An Underestimated Cause of Ischemic Monocular Visual Loss?
Introduction: Atrial fibrillation (AF) is a major cause of ischemic stroke and Transient Ischemic Attack (TIA) and investigation for paroxysmal AF is recommended following an embolic brain event. In contrast, retinal ischemic monocular blindness is traditionally considered most linked to carotid artery disease (CAS) and investigating for AF is less vigilant. We aimed to determine the prevalence of AF in patients with ischemic monocular blindness. Methods: Consecutive records of all patients presenting to a daily TIA clinic with transient or permanent ischemic monocular blindness were reviewed, January 2014-October 2016.

Evaluation of retinal injury in a rat model of transient ischemic stroke.
This study was designed to evaluate in vivo retinal injury induced by transient global cerebral ischemia/reperfusion (I/R). A stroke-induced retinal injury model in Wistar rats was established by electrocoagulation of bilateral vertebral arteries, combined with transient ligation of the bilateral common carotid arteries. Rats were randomly divided into groups based on the time post cerebral perfusion (3 h, 24 h, 48 h, 72 h, and 7 days). Retinal injury was evaluated by histological analysis, examination of eye fundus, and TUNEL staining. The expression of protein kinase C-alpha (PKCα) and fibrillary acidic protein (GFAP) w...

Retinal Vasculature Reactivity During Flicker Light Provocation, Cardiac Stress and Stroke Risk in Africans: The SABPA Study
AbstractStructural and functional similarities exist between the retinal, cerebral and, as previously suggested, the coronary microvasculature. Retinal microvascular structure and functionality (in response to flicker-light-induced-provocation (FLIP)) may relate to coronary artery disease risk and possible stroke risk. We investigated associations between retinal vessel structure, functionality and cardiac stress markers (cardiac troponin T [cTnT], amino-terminal B-type natriuretic peptide [NT-proBNP]) to translate these retina –heart relationships to stroke risk. We included 317 African and Caucasian teachers’ (aged 2...

Circulating Endothelial Markers in Retinal Vasculopathy With Cerebral Leukoencephalopathy and Systemic Manifestations Clinical Sciences
Background and Purpose—Retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations (RVCL-S) is a monogenic small vessel disease, caused by C-terminal truncating TREX1 mutations, that can be considered a model for stroke and vascular dementia. The pathophysiology of RVCL-S is largely unknown, but systemic endothelial involvement has been suggested, leading to pathology in the brain and other highly vascularized organs. Here, we investigated circulating endothelial markers to confirm endothelial involvement and identify biomarkers for disease activity.Methods—We measured circulating levels of von W...
