OBJECTIVE: As blood-brain barrier (BBB) dysfunction may occur in normal aging but may also play a pivotal role in the pathophysiology of cerebral small vessel disease (cSVD), we used dynamic contrast-enhanced (DCE)-MRI to quantify the rate and the spatial extent of BBB leakage in patients with cSVD and age- and sex-matched controls to discern cSVD-related BBB leakage from aging-related leakage. METHODS: We performed structural brain MRI and DCE-MRI in 80 patients with clinically overt cSVD and 40 age- and sex-matched controls...

BACKGROUND AND PURPOSE: Despite extensive studies on post-stroke depression (PSD), the role of the total burden of cerebral small-vessel disease (cSVD) in its pathogenesis remains unclear. METHODS: We conducted a magnetic resonance imaging (MRI)-based cohort study to investigate the relationship between total MRI burden of cSVD and PSD among patients with first-ever lacunar stroke. From June 2013 to January 2016, 374 patients were consecutively recruited. PSD was identified using the Chinese version of the Structured Clinical Interview for DSM-IV...

Hypertension is a main risk factor for the development of cerebral small vessel disease (cSVD) - a major contributor to stroke and the most common cause of vascular dementia. Despite the increasing socioeconomic importance arising from cSVD, currently only a few specific treatment strategies with proven efficacy are known. Fundamental to the lack of specific treatments is poor understanding of the disease pathogenesis and a lack of appropriate animal models resembling all symptoms of the human disease. However, chronic hypertensive rat models have been shown to bear similarities to most key features of cSVD...

OBJECTIVE: The INTERACT2 trial demonstrated beneficial effects of early intensive blood pressure (BP) lowering in intracerebral hemorrhage (ICH). However, concerns persist over harms associated with the treatment, particularly in patients with cerebral small vessel disease (CSVD) (ie white matter lesions [WML], lacunes and atrophy) and renal failure. We determined associations of CSVD, and renal failure, on outcomes in INTERACT2 participants. DESIGN AND METHOD: There were 2069/2839 patients with baseline brain CT (< 6hr ICH onset)...

OBJECTIVE: Chronic kidney disease (CKD) is associated with cerebral small vessel disease (cSVD). However, the relationship between serum cystatin C (CysC) level, a highly sensitive marker of impaired kidney function, and cSVD has not been fully understood. This study aimed to investigate the association between serum CysC level and total burden of cSVD on magnetic resonance imaging (MRI) in patients with acute lacunar stroke. MATERIALS AND METHODS: A total of 210 patients with first-ever acute lacunar stroke occurring within 1 week after onset were included in this study...

Adults with homozygous sickle cell anemia have, on average, lower cognitive function than unaffected controls. The mechanisms underlying cognitive deterioration in this population are poorly understood, but cerebral small vessel disease (CSVD) is likely to be implicated. We conducted a systematic review using the Prisma Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines of articles that included both measures of cognitive function and magnetic resonance imaging (MRI) neuroimaging markers of small vessel disease...

OBJECTIVE: Cerebral small vessel disease (cSVD) is a heterogeneous group of disorders. Screening of known cSVD genes identifies the causative mutation in <15% of familial cSVD cases. We sought to identify novel causes of cSVD. METHODS: We used linkage analysis and exome sequencing to identify the causal mutation in a French cSVD family. The identified candidate gene was then screened in 202 cSVD unrelated probands, including 1 proband from the first reported pontine autosomal dominant microangiopathy with leukoencephalopathy (PADMAL) family...

Cerebral small vessel disease (cSVD) and amyloid-β (Aβ) deposition often co-exist in (prodromal) dementia, and both types of pathology have been associated with neurodegeneration. We examined whether cSVD and Aβ have independent or interactive effects on hippocampal volume (HV) in a memory clinic population. We included 87 individuals with clinical diagnoses of Alzheimer's disease (AD) (n = 24), mild cognitive impairment (MCI) (n = 26), and subjective cognitive complaints (SCC) (n = 37). cSVD magnetic resonance imaging markers included white matter hyperintensity (WMH) volume, lacunar infarct presence, and microbleed presence...

Cerebral small vessel disease (CSVD) is a pathological process leading to lacunar infarcts, leukoaraiosis and cerebral microbleeds. Dysfunction of the blood brain barrier (BBB) has been proposed as a mechanism in the progression cerebral small vessel disease. A rodent model commonly used to study some aspects of CSVD is bilateral common carotid artery occlusion (BCCAO) in the rat. In the present study it was determined that gait impairment, as determined by a tapered beam test, and BBB permeability increased following BCCAO...

The present study aimed to evaluate whether cerebral microbleeds (CMBs), as a presentation of cerebral small vessel diseases (CSVDs), are associated with physical frailty. This is a cross-sectional evaluation in participants from a community-based study, the I-Lan Longitudinal Aging Study. The physical frail status was evaluated using the Cardiovascular Health Study score, which includes components of weakness, low physical activity, slowness, exhaustion, and weight loss. The CMBs were assessed with magnetic resonance imaging using susceptibility-weighted imaging...

BACKGROUND: Cerebral small vessel disease (cSVD), a common risk factor for cognitive impairment, involves unspecific arteriopathy characterized by hypertrophy and endothelial dysfunction that alter cerebrovascular function and auto-regulation of cerebral blood flow (CBF). Microbleedings, subcortical lacunar infarctions and diffuse areas of white matter lesions resulting from vascular injury are associated with reduced cognitive function mostly characterized by difficulties in learning and retention, attention deficits, gait disorders or depression...

Agroinfiltration was tested as a method of inoculation of chrysanthemum plants with chrysanthemum stunt viroid (CSVd). Binary vectors harboring dimeric CSVd sequences in sense and antisense orientations were constructed, and Agrobacterium transfected with these binary vectors was infiltrated into chrysanthemum leaves. Northern blotting and reverse transcription polymerase chain reaction analysis showed that local infection was established within 7 days and systemic infection within 20 days. CSVd polarities showed no difference in infectivity...

Although neuropathological conditions differ in the etiology of the inflammatory response, cellular and molecular mechanisms of neuroinflammation are probably similar in aging, hypertension, depression and cognitive impairment. Moreover, a number of common risk factors such as obesity, hypertension, diabetes and atherosclerosis are increasingly understood to act as "silent contributors" to neuroinflammation and can underlie the development of disorders such as cerebral small vessel disease (cSVD) and subsequent dementia...

Caveolin-1 (Cav-1) plays pivotal roles in the endothelial damage following stroke. The present study aimed to investigate whether serum Cav-1 level is associated with the presence of cerebral small vessel disease (cSVD) in patients with acute ischemic stroke. To this end, 156 patients were consecutively enrolled. Cranial magnetic resonance imaging was analyzed to determine the surrogates of cSVD, including cerebral microbleeds (CMBs), silent lacunar infarcts (SLIs), and white matter hyperintensities (WMHs)...

CSVd could not infect Nicotiana benthamiana when the plants were pretreated with crude leaf extract of Capsicum chinense 'Sy-2'. C. chinense leaves were revealed to contain strong RNA-digesting activity. Several studies have identified active antiviral and antiviroid agents in plants. Capsicum plants are known to contain antiviral agents, but the mechanism of their activity has not been determined. We aimed to elucidate the mechanism of Capsicum extract's antiviroid activity. Chrysanthemum stunt viroid (CSVd) was inoculated into Nicotiana benthamiana plants before or after treating the plants with a leaf extract of Capsicum chinense 'Sy-2'...

BACKGROUND: Kidney function has been related to the presence of individual markers of cerebral small vessel disease (CSVD), as lacunes, white matter hyperintensities (WMH) or microbleeds. We aimed at studying the relationship of kidney dysfunction with the combination of several markers of CSVD. METHODS: Subjects are those included in the ISSYS cohort (Investigating Silent Strokes in hypertensives: a magnetic resonance imaging study). A scale ranging from 0 to 4 points was applied based on the presence (one point each) of lacunes, deep microbleeds, moderate to extensive basal ganglia enlarged perivascular spaces (EPVS), and periventricular or deep WMH...

Chrysanthemum stunt viroid (CSVd) can infect Argyranthemum and cause serious economic loss. Low temperature treatment combined with meristem culture has been applied to eradicate viroids from their hosts, but without success in eliminating CSVd from diseased Argyranthemum. The objectives of this work were to investigate (1) the effect of low temperature treatment combined with meristem culture on elimination of CSVd, (2) the effect of low temperature treatment on CSVd distribution pattern in shoot apical meristem (SAM), and (3) CSVd distribution in flowers and stems of two infected Argyranthemum cultivars...

The toxicity risk of hyperhomocysteinemia is prevented through thiol drug administration which reduces plasma total homocysteine (tHcy) concentrations by activating thiol exchange reactions. Assuming that cysteine (Cys) is a homocysteinemia regulator, the hypothesis was verified in healthy and pathological individuals after the methionine loading test (MLT). The plasma variations of redox species of Cys, Hcy, cysteinylglycine, glutathione and albumin (reduced, HS-ALB, and at mixed disulfide, XSS-ALB) were compared in patients with cerebral small vessels disease (CSVD) (n = 11), multiple sclerosis (MS) (n = 12) and healthy controls (n = 11) at 2-4-6 h after MLT...
