Effects of transcranial magnetic stimulation combined with extracorporeal shockwave therapy for poststroke spasticity: study protocol for a randomised controlled trial.

Introduction: Spasticity is a common complication of stroke, which is related to poor motor recovery and limitations in the performance of activities. Both transcranial magnetic stimulation (TMS) and extracorporeal shockwave therapy (ESWT) are effective treatment methods for poststroke spasticity (PSS). However, there is no existing study exploring the safety and effectiveness of TMS combined with ESWT for PSS.

Roles of blood monocytes carrying TREM2 mutation in pathogenesis of Alzheimer's disease and its therapeutic potential in APP/PS1 mice.

Introduction: The triggering receptor expressed on myeloid cells 2 (TREM2) arginine-47-histidine (R47H) mutation is a significant risk for Alzheimer's disease (AD) with unclear mechanisms. Previous studies focused on microglial amyloid-β (Aβ) phagocytosis with less attention on the impact of TREM2 mutation on blood monocytes.

Methods: Bone marrow transplantation (BMT) models were used to assess the contribution of blood monocytes carrying TREM2 mutation to AD.

Intermittent Theta-Burst Stimulation for Stroke: Primary Motor Cortex Versus Cerebellar Stimulation: A Randomized Sham-Controlled Trial.

Background: Stroke survivors with impaired balance and motor function tend to have relatively poor functional outcomes. The cerebellum and primary motor cortex (M1) have been suggested as targets for neuromodulation of balance and motor recovery after stroke. This study aimed to compare the efficacy and safety of intermittent theta-burst stimulation (iTBS) to the cerebellum or M1 on balance and motor recovery in patients with stroke.

Intermittent Theta Burst Stimulation Attenuates Cognitive Deficits and Alzheimer's Disease-Type Pathologies via ISCA1-Mediated Mitochondrial Modulation in APP/PS1 Mice.

Intermittent theta burst stimulation (iTBS), a time-saving and cost-effective repetitive transcranial magnetic stimulation regime, has been shown to improve cognition in patients with Alzheimer's disease (AD). However, the specific mechanism underlying iTBS-induced cognitive enhancement remains unknown. Previous studies suggested that mitochondrial functions are modulated by magnetic stimulation.

Prevalence and clinical predictors of spasticity after intracerebral hemorrhage.

Background: Spasticity is a common complication of intracerebral hemorrhage (ICH). However, no consensus exists on the relation between spasticity and initial clinical findings after ICH.

Methods: This retrospective study enrolled adult patients with a history of ICH between January 2012 and October 2020.

Activation of Dopamine D2 Receptors Alleviates Neuronal Hyperexcitability in the Lateral Entorhinal Cortex via Inhibition of HCN Current in a Rat Model of Chronic Inflammatory Pain.

Functional changes in synaptic transmission from the lateral entorhinal cortex to the dentate gyrus (LEC-DG) are considered responsible for the chronification of pain. However, the underlying alterations in fan cells, which are the predominant neurons in the LEC that project to the DG, remain elusive. Here, we investigated possible mechanisms using a rat model of complete Freund's adjuvant (CFA)-induced inflammatory pain.

p75NTR Ectodomain Ameliorates Cognitive Deficits and Pathologies in a Rapid Eye Movement Sleep Deprivation Mice Model.

The neurotrophin receptor p75 (p75NTR) is a circadian rhythm regulator and mediates cognitive deficits induced by sleep deprivation (SD). The soluble extracellular domain of p75NTR (p75ECD) has been shown to exert a neuroprotective function in Alzheimer's disease (AD) and depression animal models. Nevertheless, the role of p75ECD in SD-induced cognitive dysfunction is unclear.

Rehabilitation Therapy for Vocal Fold Paralysis Caused by Lung Cancer: A Case Report.

Objective: Unilateral vocal fold paralysis (UVFP) can be caused by iatrogenic injury or tumor-induced damage to the recurrent laryngeal nerve. Studies of comprehensive rehabilitation therapies for patients suffering from severe UVFP are limited. The purpose of this case report is to describe an improvement in complete aphonia after comprehensive rehabilitation therapies in a patient with severe UVFP due to a lung tumor.

Neurotrophin receptor p75 mediates amyloid β-induced tau pathology.

Neurofibrillary tangles of hyperphosphorylated tau protein (p-tau) are a key pathological feature of Alzheimer's disease (AD). Tau phosphorylation is suggested to be secondary to amyloid-beta (Aβ) accumulation. However, the mechanism by which Aβ induces tau phosphorylation in neurons remains unclear.

The ProNGF/p75NTR pathway induces tau pathology and is a therapeutic target for FTLD-tau.

Tau pathology is characterized as a form of frontotemporal lobar degeneration (FTLD) known as FTLD-tau. The underlying pathogenic mechanisms are not known and no therapeutic interventions are currently available. Here, we report that the neurotrophin receptor p75NTR plays a critical role in the pathogenesis of FTLD-tau.

Cysteine-Rich Repeat Domains 2 and 4 are Amyloid-β Binding Domains of Neurotrophin Receptor p75NTR and Potential Targets to Block Amyloid-β Neurotoxicity.

The p75 neurotrophin receptor (p75NTR) is an amyloid-β (Aβ) receptor that both mediates Aβ neurotoxicity and regulates Aβ production and deposition, thus playing an important role in the pathogenesis of Alzheimer's disease (AD). The extracellular domain of p75NTR (p75ECD), consisting of four cysteine-rich repeat domains (CRDs), was recently reported to be an endogenous anti-Aβ scavenger to block p75NTR-mediated neuronal death and neurite degeneration signaling of Aβ and pro-neurotrophins. Identification of the specific Aβ binding domains of p75NTR is crucial for illuminating their interactions and the etiology of AD.

Cerebrospinal Fluid Amyloid-β Levels are Increased in Patients with Insomnia.

Previous studies demonstrate that patients with sleep disorders are at risk of developing Alzheimer's disease (AD), with the mechanism unknown. It is suggested that acute sleep deprivation induces an increase of amyloid-β (Aβ), the major pathological agent in AD, in the cerebrospinal fluid (CSF). In the present study, we recruited 23 patients with chronic insomnia aged between 46 to 67 years and 23 healthy controls aged between 43 to 67 years.

Comorbidity Burden of Dementia: A Hospital-Based Retrospective Study from 2003 to 2012 in Seven Cities in China.

Dementia is increasing dramatically and imposes a huge burden on society. To date, there is a lack of data on the health status of patients with dementia in China. In an attempt to investigate the comorbidity burden of dementia patients in China at the national level, we enrolled 2,938 patients with Alzheimer's disease (AD), vascular dementia (VaD), or other types of dementia, who were admitted to tertiary hospitals in seven regions of China from January 2003 to December 2012.

Reduced Cardiovascular Functions in Patients with Alzheimer's Disease.

Previous studies have suggested that cardiovascular functions might play a critical role in Alzheimer's disease (AD) pathogenesis. However, the relationship among heart function, blood flow of cerebral vessels, and AD remains unclear. In the present study, AD patients (n = 34) and age- and gender-matched cognitively normal controls (n = 34) were recruited.

Peritoneal dialysis reduces amyloid-beta plasma levels in humans and attenuates Alzheimer-associated phenotypes in an APP/PS1 mouse model.

Clearance of amyloid-beta (Aβ) from the brain is an important therapeutic strategy for Alzheimer's disease (AD). Current studies mainly focus on the central approach of Aβ clearance by introducing therapeutic agents into the brain. In a previous study, we found that peripheral tissues and organs play important roles in clearing brain-derived Aβ, suggesting that the peripheral approach of removing Aβ from the blood may also be effective for AD therapy.

Association of dementia with death after ischemic stroke: A two-year prospective study.

The association between dementia and the risk of death after ischemic stroke was investigated. Neurological, neuropsychological and functional assessments were evaluated in 619 patients with acute ischemic stroke. Dementia was diagnosed at admission and at three months after stroke onset.

Interleukin-18 gene promoter 607A polymorphism, but not 137C polymorphism, is a protective factor for ischemic stroke in the Chinese population: A meta-analysis.

Some epidemiological studies have evaluated the association between interleukin (IL)-18 promoter polymorphisms and the risk of ischemic stroke (IS), but the results were inconsistent. The present meta-analysis was therefore performed to investigate the relationship between IL-18 promoter 137G/C and 607C/A polymorphisms and the risk of IS in the Chinese population. Related studies from PubMed, Embase, Web of Science, CBMdisc and CNKI databases up to November 1, 2014 were systematically searched, also the reference lists of identified articles were manually searched.

PPARγ Inhibits VSMC Proliferation and Migration via Attenuating Oxidative Stress through Upregulating UCP2.

Increasing evidence showed that abnormal proliferation and migration of vascular smooth muscle cells (VSMCs) are common event in the pathophysiology of many vascular diseases, including atherosclerosis and restenosis after angioplasty. Among the underlying mechanisms, oxidative stress is one of the principal contributors to the proliferation and migration of VSMCs. Oxidative stress occurs as a result of persistent production of reactive oxygen species (ROS).

SIRT1 improves VSMC functions in atherosclerosis.

Despite advancements in diagnosis and treatment of cardiovascular diseases (CVDs), the morbidity and mortality of CVDs are still rising. Atherosclerosis is a chronic inflammatory disease contributing to multiple CVDs. Considering the complexity and severity of atherosclerosis, it is apparent that exploring the mechanisms of atherosclerotic formation and seeking new therapies for patients with atherosclerosis are required to overcome the heavy burden of CVDs on the quality and length of life of the global population.

Impaired SIRT1 promotes the migration of vascular smooth muscle cell-derived foam cells.

The formation of fat-laden foam cells, contributing to the fatty streaks of the plaques of atheroma, is the critical early process in atherosclerosis. The previous study demonstrated that vascular smooth muscle cells (VSMCs) contain a much larger burden of the excess cholesterol in comparison with monocyte-derived macrophages in human coronary atherosclerosis, as the main origin of foam cells. It is noteworthy that VSMC-derived foam cells are deposited in subintima but not media, where VSMCs normally deposit in.

An overview of potential molecular mechanisms involved in VSMC phenotypic modulation.

The fully differentiated medial vascular smooth muscle cells (VSMCs) of mature vessels keep quiescent and contractile. However, VSMC can exhibit the plasticity in phenotype switching from a differentiated and contractile phenotype to a dedifferentiated state in response to alterations in local environmental cues, which is called phenotypic modulation or switching. Distinguishing from its differentiated state expressing more smooth muscle (SM)-specific/selective proteins, the phenotypic modulation in VSMC is characterized by an increased rate of proliferation, migration, synthesis of extracellular matrix proteins and decreased expression of SM contractile proteins.

The role of TRPV1 in improving VSMC function and attenuating hypertension.

The transient receptor potential vanilloid type 1 (TRPV1) channel, a ligand-gated cation channel of the TRP subfamily, can be activated by multiple stimuli, including capsaicin. Currently, cumulative studies have demonstrated an interesting link between TRPV1 and cardiovascular diseases, including hypertension. Additionally, the protective effect of TRPV1 against hypertension and its related disorders has been proved to be partly involved with the improved action of vascular smooth muscle cells (VSMCs).

A meta-analysis of the relationship between MTHFR gene A1298C polymorphism and the risk of adult stroke.

Background: The association between methylenetetrahydrofolate reductase (MTHFR) gene A1298C polymorphism and adult stroke remains controversial. The present article was designed to clarify this relationship through pooled analysis of the numerous epidemiological studies focusing on this association.

Methods: We comprehensively searched all published papers in electronic database including PubMed, Embase, Web of Science, Chinese Biomedical Literature on disc (CBMdisc) and China National Knowledge Infrastructure (CNKI) up to 2013.

Telmisartan-induced PPARγ activity attenuates lipid accumulation in VSMCs via induction of autophagy.

Foam cell formation is the hallmark of atherosclerosis. Both telmisartan and autophagy protect against the development of atherosclerosis. However, it has yet to be elucidated whether telmisartan prevents vascular smooth muscle cell (VSMC)-derived foam cell formation.
