Effect of Inflammation on the Process of Stroke Rehabilitation and Poststroke Depression
Conclusions Stroke comprises ischemic stroke and ICH. The immuno-inflammatory process is involved in neural plasticity following events such as a hemorrhage or ischemic stroke. After ischemia, astrocytes, microglia, and MDMs play important roles during rehabilitation with the modulation of cytokines or chemokines, such as TNF-α and IL-1. Moreover, MiRNAs are also important posttranscriptional regulators in these glial mitochondrial responses to cerebral ischemia. ICH involves processes similar and different to those seen in ischemia, including neuronal injury, astrocytic and microglial/macrophage activation, and n...

Anxiety in Patients With Acute Ischemic Stroke: Risk Factors and Effects on Functional Status
Conclusion: Depressive symptoms are the major correlates of PSA while more severe PSA is associated with poorer ADL and health-related QOL. Acute lesions involving CHWM may correlate with PSA in ischemic stroke patients with mild-to-moderate neurologic deficits, supporting a lesion-location hypothesis in PSA.IntroductionAnxiety is prevalent after stroke and occurs in about one-quarter of stroke survivors (1, 2). Poststroke anxiety (PSA) may have a negative impact on quality of life (QOL) of stroke survivors, affecting their rehabilitation (3). Furthermore, one prospective study found that severe anxiety symptoms were assoc...

A Post-hoc Study of D-Amino Acid Oxidase in Blood as an Indicator of Post-stroke Dementia
In conclusion, our data support that plasma DAO levels were increased in PSD patients and correlated with brain WMH, independent of age, gender, hypertension, and renal function. Plasma DAO levels may therefore aid in PSD diagnosis. Introduction Stroke is a risk factor for both vascular dementia and Alzheimer's disease (1, 2). Functional recovery develops over the course of 26 weeks after a stroke (3), but the survivors are often left with disabilities. In addition to the sequelae of acute neuronal damage, the 1-year post-stroke dementia (PSD) rates after first-ever and recurrent stroke are ~10 and 30...

Mediterranean diet: The role of long-chain ω-3 fatty acids in fish; polyphenols in fruits, vegetables, cereals, coffee, tea, cacao and wine; probiotics and vitamins in prevention of stroke, age-related cognitive decline, and Alzheimer disease.
Authors: Román GC, Jackson RE, Gadhia R, Román AN, Reis J Abstract The mechanisms of action of the dietary components of the Mediterranean diet are reviewed in prevention of cardiovascular disease, stroke, age-associated cognitive decline and Alzheimer disease. A companion article provides a comprehensive review of extra-virgin olive oil. The benefits of consumption of long-chain ω-3 fatty acids are described. Fresh fish provides eicosapentaenoic acid while α-linolenic acid is found in canola and soybean oils, purslane and nuts. These ω-3 fatty acids interact metabolically with ω-6 fatty acids mainly linoleic...

Tyrosine Kinase Inhibitor as a new Therapy for Ischemic Stroke and other Neurologic Diseases: is there any Hope for a Better Outcome?
Abstract The relevance of tyrosine kinase inhibitors (TKIs) in the treatment of malignancies has been already defined. Aberrant activation of tyrosine kinase signaling pathways has been causally linked not only to cancers but also to other non-oncological diseases. This review concentrates on the novel plausible usage of this group of drugs in neurological disorders, such as ischemic brain stroke, subarachnoid hemorrhage, Alzheimer's disease, multiple sclerosis. The drugs considered here are representatives of both receptor and non-receptor TKIs. Among them imatinib and masitinib have the broadest spectrum of ther...

Post-ischemia common carotid artery occlusion worsens memory loss, but not sensorimotor deficits, in long-term survived stroke mice
Brain Res Bull. 2022 Mar 15:S0361-9230(22)00077-6. doi: 10.1016/j.brainresbull.2022.03.008. Online ahead of print.ABSTRACTIschemic stroke in rodents is usually induced by intraluminal occlusion of the middle cerebral artery (MCA) via the external carotid artery (ECA) or the common carotid artery (CCA). The latter route requires permanent CCA occlusion after ischemia, and here, we assess its effects on long-term outcomes. Transient occlusion of MCA and CCA was performed at normal body temperature. After 90minutes of ischemia, mice were randomized to permanent CCA occlusion or no occlusion (control group). Body weight, and m...

Protective Effects of Spatholobi Caulis Extract on Neuronal Damage and Focal Ischemic Stroke/Reperfusion Injury
AbstractNeuronal apoptotic cell death plays an important role in many neurological disorders, including Alzheimer ’s disease, Parkinson’s disease, and ischemic stroke. Spatholobi Caulis (SC) has been widely used in traditional herbal medicine for the treatment of cancer, inflammation, viral infection, and anemia. However, the protective effects of SC extract (SCE) against apoptotic cell death in the brain h ave not been reported. We investigated the protective effects of SCE against neuronal injury etoposide-induced neurotoxicity and in rats subjected to focal transient ischemic stroke middle cerebral artery occlusion ...

A Hallmark Clinical Study of Cord Blood Therapy in Adults with Ischemic Stroke.
Abstract The therapeutic application of human umbilical cord blood cells has been an area of great interest for at least the last 25 years. Currently, cord blood cells are approved for reconstitution of the bone marrow following myeloablation in both young and old patients with myeloid malignancies and other blood cancers. Translational studies investigating alternative uses of cord blood have also shown that these cells not only stimulate neurogenesis in the aged brain but are also potentially therapeutic in the treatment of adult neurodegenerative disorders including amyotrophic lateral sclerosis, Alzheimer's di...

β2-Microglobulin exacerbates neuroinflammation, brain damage, and cognitive impairment after stroke in rats
In this study, we established a rat model of focal cerebral ischemia by occlusion of the middle cerebral artery. We found that β2M levels in the cerebral spinal fluid, serum, and brain tissue were significantly increased in the acute period but gradually decreased during the recovery period. RNA interference was used to inhibit β2M expression in the acute period of cerebral stroke. Tissue staining with 2,3,5-triphenyltetrazolium chloride and evaluation of cognitive function using the Morris water maze test demonstrated that decreased β2M expression in the ischemic penumbra reduced infarct volume and alleviated cognitive...

GSE223628 Therapeutic modulation of the blood-brain barrier and ischemic stroke by a bioengineered FZD4-selective WNT surrogate (bulk)
Contributors : Jie Ding ; Kanako Yuki ; Calvin KuoSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusDerangements of the blood-brain barrier (BBB) or blood-retinal barrier (BRB) occur in disorders ranging from stroke, cancer, diabetic retinopathy, and Alzheimer's disease. The Norrin/FZD4/TSPAN12 pathway activates WNT/ -catenin signaling, which is essential for BBB and BRB function. However, systemic pharmacologic FZD4 stimulation is hindered by obligate palmitoylation and insolubility of native WNTs and suboptimal properties of the FZD4-selective ligand Norrin. Here, we developed L6-F...

Potential Applications of Remote Limb Ischemic Conditioning for Chronic Cerebral Circulation Insufficiency
Conclusion Due to its long-term and often invisible course, CCCI has received less attention than acute cerebral ischemic stroke. However, without appropriate intervention, CCCI may lead to a variety of adverse events. Because the pathophysiological changes associated with CCCI are complex, pharmacological research in this area has been disappointing. Recent research suggests that RLIC, which is less invasive and more well-tolerated than drug treatment, can activate endogenous protective mechanisms during CCCI. In the present report, we reviewed studies related to CCCI (Table 1), as well as those related to stroke and sta...

Effects of Neurotrophic Factors in Glial Cells in the Central Nervous System: Expression and Properties in Neurodegeneration and Injury
Conclusion and Future Aspects This review summarizes available NTF expression data, compiles existing evidence on the effects of glial NTF signaling in healthy conditions and in disease models (Figure 1), and highlights the importance of this topic for future studies. The relationship between NTFs and glia is crucial for both the developing and adult brain. While some of these factors, such as NT-3 and CNTF, have highly potent effects on gliogenesis, others like BDNF and GDNF, are important for glia-mediated synapse formation. Neurotrophic factors play significant roles during neurodegenerative disorders. In many cases, ...
