Transcranial Doppler ultrasound: Clinical applications from neurological to cardiological setting
J Clin Ultrasound. 2022 Oct;50(8):1212-1223. doi: 10.1002/jcu.23344.ABSTRACTTranscranial Doppler (TCD) ultrasonography is a rapid, noninvasive, real-time, and low-cost imaging technique. It is performed with a low-frequency (2 MHz) probe in order to evaluate the cerebral blood flow (CBF) and its pathological alterations, through specific acoustic windows. In the recent years, TCD use has been expanded across many clinical settings. Actually, the most widespread indication for TCD exam is represented by the diagnosis of paradoxical embolism, due to patent foramen ovale, in young patients with cryptogenic stroke. In addition...

In vitro study about prevention of vascular reocclusion by low intensity ultrasonic irradiation
Drug Discov Ther. 2022 Oct 9. doi: 10.5582/ddt.2022.01064. Online ahead of print.ABSTRACTFor the treatment of acute ischemic stroke, the current standard of care is thrombolysis by the administration of intravenous (IV) recombinant tissue-type plasminogen activator (rt-PA). Although this approach is proven to be effective, reocclusion within 24 hours occurs in about 20% of patients who receive recanalization by rt-PA. In addition, the administration of anticoagulants within 24 hours after IV rt-PA increases the risk of intracranial hemorrhage; therefore, treatment with anticoagulants is contraindicated in this population. ...

MicroRNA and Hemostasis Profile of Carotid Atherosclerosis
We described the miRNA and hemostasis profile of patients with moderate and advanced stages of carotid atherosclerosis and elucidated potential correlations with hemostatic activation. A prospective case-control study included 61 patients with evidence of carotid atherosclerosis (via ultrasound). The study population was divided into groups depending on the degree of carotid artery stenosis: 60% or more (advanced) and <60% (moderate). All patients underwent the following blood tests: general blood test, hemostatic parameters and microRNA. Extraction of microRNA was performed using Leukocyte RNA Purification Kit (NOR...

Carotid contrast-enhanced ultrasonography combined with sirtuin-3 in the diagnosis of plaques in carotid atherosclerosis
CONCLUSIONS: A low expression of SIRT3 predicted a higher risk for unstable plaques in CAS patients. The combination of CEUS and SIRT3 is a potential strategy for diagnosing unstable plaques.PMID:36083252 | DOI:10.17219/acem/152471

High systemic immune-inflammation index is associated with carotid plaque vulnerability: New findings based on carotid ultrasound imaging in patients with acute ischemic stroke
This study sought to explore the relationship between SII level and carotid plaque vulnerability, plaque composition characteristics, and acute ischemic stroke (AIS) severity. A total of 131 patients diagnosed with AIS presenting with a carotid atherosclerotic plaque were enrolled in this study. Using carotid ultrasound (CDU) to assess the carotid-responsible plaque properties, we divided the patients into stable plaques group and vulnerable plaques group, and analyzed the correlation between SII levels and plaque vulnerability. And we further analyzed to evaluate the correlation between high SII levels and plaque characte...

The study of serum C-reactive protein, Serum cystatin C, and carbohydrate antigen 125 in patients with acute ischemic stroke
Cell Mol Biol (Noisy-le-grand). 2022 May 31;68(5):89-95. doi: 10.14715/cmb/2022.68.5.12.ABSTRACTStroke is the most common, deadly, and complicating neurological disease. Many studies have shown that the levels of some acute inflammatory reactants in people with ischemic stroke are higher than average. Therefore, in this study, three acute inflammatory reactants, i.e., C-reactive protein, Serum cystatin C, and carbohydrate antigen 125, were evaluated in patients with acute ischemic stroke to consider the association between these serums with intra and extra-cerebral vessels stenosis. In this cross-sectional study, 90 patien...
