Image-based visualization of stents in mechanical thrombectomy for acute ischemic stroke: Preliminary findings from a series of cases.

Background: Mechanical thrombectomy is the most effective treatment for great cerebral artery embolization within a set time window. Typically, an arteriogram does not show the localization of the stent after release and whether a thrombus is captured or not. Thus, improving the visualization of a stent in interventional therapy will be helpful for clinicians.

Detection rate and shunt grading with synchronous testing of contrast transcranial Doppler and contrast transthoracic echocardiography: Preliminary findings.

Patent foramen ovale, a common congenital atrial septal defect, may lead to cardiac right-to-left shunting (RLS), which has been associated with various diseases. Reliable techniques for detecting RLS are essential for diagnosis and assist with treatment decision-making. Contrast transcranial Doppler (c-TCD), contrast transthoracic echocardiography (c-TTE), and contrast transesophageal echocardiography can be used to detect RLS.

Efficacy and safety of intensified antithrombotic therapy followed by stenting in treatment of highly severe stenosis accompanied by thrombosis in carotid atherosclerosis.

Objective: This study explored the efficacy and safety of intensified antithrombotic therapy followed by stenting in treatment of highly severe stenosis accompanied by thrombosis in patients with carotid atherosclerosis (CAS).

Methods: This study recruited a total of 24 CAS patients between June 2016 and November 2020 in the research group, who had highly severe stenosis accompanied by in situ thrombosis and were treated with intensified antithrombotic treatment followed by stenting. The control group included 17 patients treated with stent angioplasty immediately after diagnosis with stenosis and thrombosis between January 2012 and May 2016.

Inspiratory laryngeal stridor as the main feature of progressive encephalomyelitis with rigidity and myoclonus: a case report and literature review.

Background: Progressive encephalomyelitis with rigidity and myoclonus (PERM) is an acute, potentially life-threatening, yet curable neuro-immunological disease characterized by spasms, muscular rigidity, and brainstem and autonomic dysfunction. The clinical features of glycine receptor (GlyR) antibody-positive PERM may be overlooked, particularly with some unusual symptoms.

Case Presentation: A 52-year-old man was admitted to the hospital for evaluation of tension headache for 20 days and mild dysarthria.

Cytomegalovirus-Associated Mild Encephalopathy/Encephalitis With Reversible Splenial Lesion.

Introduction: Mild encephalopathy with a reversible splenial lesion (MERS) is a clinical-radiologic syndrome presenting with a reversible lesion in the splenium of the corpus callosum. MERS is associated with many potential etiologies, including cytomegalovirus (CMV) infection in children. We report an adult patient with CMV-associated MERS.

Synthesis of Pentafluoroethyl Ethers by Silver-Mediated Oxidative Pentafluoroethylation of Alcohols and Phenols.

A silver triflate (AgOTf)-mediated oxidative pentafluoroethylation of alcohols and phenols with nucleophilic (pentafluoroethyl)trimethylsilane (TMSCFCF) using selectfluor as oxidant under mild reaction conditions was developed. This oxidative coupling protocol utilizes broadly available substrates and easily handled reagents to afford various pentafluoroethyl ethers in moderate to excellent yields. Furthermore, this method was extended to the oxidative heptafluoropropylation and ethoxycarbonyldifluoromethylation of alcohols and phenols for preparation of the corresponding fluoroalkyl ethers.

Angioplasty and stenting for patients with symptomatic intracranial atherosclerosis: study protocol of a randomised controlled trial.

Introduction: Whether adding percutaneous transluminal angioplasty and stenting (PTAS) to background medical treatment is effective for decreasing the incidence of stroke or death in patients with symptomatic intracranial atherosclerosis (ICAS) is still controversial. We perform a randomised controlled trial to examine the effectiveness and safety of an improved PTAS procedure for patients with ICAS.

Methods And Analysis: A randomised controlled trial will be conducted in three hospitals in China.

Efficacy of Solitaire Stent Arterial Embolectomy in Treating Acute Cardiogenic Cerebral Embolism in 17 Patients.

BACKGROUND Thrombolysis with rtPA is the only accepted drug therapy for acute ischemic stroke. Since acute cerebral stroke is so pervasive, newly developed recanalization methods have the potential for wide-ranging impacts on patient health and safety. We explored the efficacy and safety of Solitaire stent arterial embolectomy in the treatment of acute cardiogenic cerebral embolism.

High Dose of Atorvastatin for the Treatment of Contrast-Induced Nephropathy After Carotid Artery Stenting.

Statins have been used to prevent contrast-induced nephropathy (CIN). However, the optimal dose of statins is still under controversy. This study aimed to investigate the optimal dose of atorvastatin for the treatment of CIN after carotid artery stenting (CAS).

Self-organization of chaos synchronization and pattern formation in coupled chaotic oscillators.

Pattern formation in spatiotemporal chaotic systems is investigated. Temporally chaotic and spatially ordered patterns are observed by varying the coupling strength. Spatial orderings emerge spontaneously due to self-organization of partial and nonlocal chaos synchronization, governed by various types of spatial symmetries.
