Neuroprotective effect of CuATSM in mice stroke model by ameliorating oxidative stress.

Cu-diacetyl-bis (N4-methylthiosemicarbazone) (CuATSM) has both anti-oxidative and anti-inflammatory activities, but its therapeutic efficacy for oxidative stress has not been thoroughly investigated in acute ischemic stroke. Here, the present study was designed to assess the efficacies of CuATSM in acute ischemic stroke by comparing with the standard neuroprotective reagent edaravone. Mice were subjected to transient middle cerebral occlusion (tMCAO) for 60 min, and then intravenously administrated with CuATSM (1.

Improvement of a decreased anti-oxidative activity by edaravone in amyotrophic lateral sclerosis patients.

Background: The free radical scavenger edaravone is a proven neuroprotective drug for patients with amyotrophic lateral sclerosis (ALS). Our objective was to evaluate the therapeutic effects of edaravone for oxidative stress and anti-oxidative activity in ALS patients.

Methods: Twenty-two ALS patients with a disease duration of 2 years, treated by edaravone, and 25 control participants were evaluated according to their clinical scores, including ALS functional rating scale-revised (ALSFRS-R), and serum and cerebrospinal fluid (CSF) markers of oxidative stress dROM and anti-oxidative activity OXY.

A Polyphenolic Complex Attenuates Inflammatory Response and Blood- Brain Barrier Disruption.

Background: Cerebral ischemia causes a strong inflammatory response. Neumentix is a dietary supplement containing 14.9% rosmarinic acid and 29.

Up-regulation of sphingosine-1-phosphate receptors and sphingosine kinase 1 in the peri-ischemic area after transient middle cerebral artery occlusion in mice.

There is thought to be a strong relationship between sphingosine-1-phosphate (S1P) signaling and pathophysiolosy of cerebral ischemia. We examined the change of expression and distribution of S1P receptors (S1PRs) and sphingosine kinases (SphKs) after cerebral ischemia in male C57BL6/J mice using immunohistochemical analysis at 1, 5, 14, and 28 days after 30 min of transient middle cerebral artery occlusion (tMCAO). S1PR1, 3, and 5 were transiently induced in the cells, which were morphologically similar to neurons in the peri-infarct lesion with a peak seen at 1 day after tMCAO (p < 0.

Early Emergence of Neuropsychiatric Symptoms in Cognitively Normal Subjects and Mild Cognitive Impairment.

The world is rapidly aging and facing an increase in the number of dementia patients, so it is important to detect the preclinical stage of dementia in such countries. We examined both cognitive and affective functions among cognitively normal control (n = 218), mild cognitive impairment (MCI, n = 146), and Alzheimer's disease (AD, n = 305) subjects using two evaluation tools for behavioral and psychological symptoms of dementia (BPSD) [Abe's BPSD score (ABS) and mild behavioral impairment (MBI)]. BPSD were present in 12.

Female dominant association of sarcopenia and physical frailty in mild cognitive impairment and Alzheimer's disease.

Associations of sarcopenia and physical frailty in cognitive and affective (depression, apathy, and behavioral and psychological symptoms of dementia) functions of mild cognitive impairment (MCI) and Alzheimer's disease (AD) were not fully evaluated previously, especially not for gender differences. 165 AD, 84 MCI, and 48 control participants (175 female, 122 male) were evaluated for cognitive, affective, activities of daily living (ADL), and physical functions associated with sarcopenia and physical frailty. In both sexes, cognitive and affective functions, ADL, and physical functions worsened in MCI and AD compared to control subjects.

Chronic cerebral hypoperfusion alters amyloid-β transport related proteins in the cortical blood vessels of Alzheimer's disease model mouse.

Abnormal accumulation of amyloid-β (Aβ) peptide defines progression of Alzheimer's disease (AD) pathology in brain. Here, we investigated expressive changes of two main Aβ transport receptors low-density lipoprotein receptor related protein-1 (LRP1) and receptor for advanced glycation end products (RAGE) in a novel AD mice (APP23) with chronic cerebral hypoperfusion (CCH) model, moreover, examined a protective effect of a free radical scavenger edaravone (Eda). In contrast to wild type (WT) and APP23 mice, CCH strongly accelerated abnormal Aβ40 depositions and cerebral amyloid angiopathy (CAA) pathology, increased both LRP1 and RAGE expressions in brain parenchyma, while a decrease of LRP1 and an increase of RAGE were observed in vascular endothelial cells at age 12 months (M) of AD mice.

Clinical and Pathological Benefits of Edaravone for Alzheimer's Disease with Chronic Cerebral Hypoperfusion in a Novel Mouse Model.

Alzheimer's disease (AD) and chronic cerebral hypoperfusion (CCH) often coexist in dementia patients in aging societies. The hallmarks of AD including amyloid-β (Aβ)/phosphorylated tau (pTau) and pathology-related events such as neural oxidative stress and neuroinflammation play critical roles in pathogenesis of AD with CCH. A large number of lessons from failures of drugs targeting a single target or pathway on this so complicated disease indicate that disease-modifying therapies targeting multiple key pathways hold potent potential in therapy of the disease.

Imaging Hypoxic Stress and the Treatment of Amyotrophic Lateral Sclerosis with Dimethyloxalylglycine in a Mice Model.

Hypoxia inducible factor-1α (HIF-1α) is a key transcription factor that maintains oxygen homeostasis. Hypoxic stress is related to the pathogenesis of amyotrophic lateral sclerosis (ALS), and impaired HIF-1α induces motor neuron degeneration in ALS. Dimethyloxalylglycine (DMOG) upregulates the stability of HIF-1α expression and shows neuroprotective effects, but has not been used in ALS as an anti-hypoxic stress treatment.

A Rare Case of Klinefelter Syndrome Accompanied by Spastic Paraplegia and Peripheral Neuropathy.

Klinefelter syndrome is a chromosomal disorder with a typical karyotype of 47, XXY, accompanied by various neurological symptoms. We herein report the first case of Klinefelter syndrome with a rare mosaic form of 47, XXY and 48, XXXY, combined with both spastic paraplegia and peripheral motor neuropathy. This case showed spasticity and hyperreflexia with pathological reflexes and ankle clonus as well as muscle weakness in all extremities.

Behavioral and affective features of amyotrophic lateral sclerosis patients.

Evaluating the cognitive and behavioral features in amyotrophic lateral sclerosis (ALS) patients is important for therapy and care. Fifty-seven ALS, 5 ALS with the behavioral variant of frontotemporal dementia (FTD) (ALS-FTD), 12 FTD patients, and 35 control subjects were evaluated by 10 different tests for cognitive and behavioral (mini-mental state examination (MMSE), Hasegawa dementia rating scale - revised (HDS-R), frontal assessment battery (FAB), Montreal cognitive assessment (MoCA), ALS-frontotemporal dementia-Questionnaire (ALS-FTD-Q), and anosognosia scale), affective (depression, apathy, and behavioral and psychological symptoms of dementia (BPSD)), and activities of daily living (ADL) assessments. The motor functions of ALS patients were evaluated by ALS functional rating scale - revised (ALSFRS-R) and modified Norris scale.

A migration case of Kii amyotrophic lateral sclerosis/parkinsonism dementia complex with the shortest stay in the endemic area and the longest incubation to develop the disease.

Amyotrophic lateral sclerosis/parkinsonism dementia complex (ALS/PDC) is an endemic disease observed in the Kii peninsula, Guam, and Papua. We report a case of a 76-year old man with ALS/PDC of the Kii peninsula of Japan (Kii ALS/PDC). The patient was born and grew up in the Kii peninsula.

Chronic Lymphocytic Inflammation with Pontine Perivascular Enhancement Responsive to Steroids (CLIPPERS) with Limbic Encephalitis.

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is an inflammatory central nervous system disorder that mainly involves in the brainstem, basal ganglia and cerebellum. We herein report the case of a patient with CLIPPERS, which was diagnosed based on the clinical and radiological features. After initially responded to steroid treatment, the patient developed limbic encephalitis.

Successful Delayed Aortic Surgery for a Patient with Ischemic Stroke Secondary to Aortic Dissection.

The diagnosis of aortic dissection (AD) is sometimes difficult within the limited time window of recombinant tissue plasminogen activator (tPA) for ischemic stroke (IS). A 60-year-old man developed sudden left hemiparesis due to IS. During tPA infusion, his blood pressure dropped and consciousness declined.

Potential multisystem degeneration in Asidan patients.

Objective: To evaluate a potential multisystem involvement of neurodegeneration in Asidan, in addition to cerebellar ataxia and signs of motor neuron disease.

Methods: We compared the new Asidan patients and those identified in previous studies with Parkinson's disease (PD, n=21), and progressive supranuclear palsy (PSP, n=13) patients using I-2β-Carbomethoxy-3β-(4-iodophenyl)-N-(3-fluoropropyl) nortropane (I-FP-CIT) dopamine transporter single photon emission computed tomography (DAT-SPECT) and I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy (Asidan, DAT: n=10; MIBG: n=15).

Results: Both the PD and PSP groups served as positive controls for DAT decline.
