Abstract
Cardiovascular diseases represent the leading cause of mortality worldwide, with recent epidemiological studies revealing an increasing trend of prevalence and incidence globally. Among cardiovascular disorders, both arterial and venous thrombosis and particularly their acute life-threating complications such as ischemic stroke, acute myocardial infarction, deep venous thrombosis and pulmonary embolism are responsible for more than 25% of all deaths worldwide. The modern approach following progresses in anticoagulant, thrombolytic and antiaggregant therapies has significantly improved the prognoses of these conditions in the last past decades. However, several challenges still remain such as achieving the optimal drug concentration at the injured site, reducing the shortcomings of drug resistance and the incidence of life-threatening hemorrhages. Nanomedicine is a well-known field of medicine in which atomic and molecular structures ranging between 0.1–100 nm are used in various domains due to their specific mechanical, electrical, thermal and magnetic properties. Recent experimental and clinical evidence have shown that nanotechnology could be a safe, effective and an appealing approach for various non-cardiovascular and cardiovascular diseases such as thromboembolic conditions. In this review, we have described the most promising nanotechnology-based approaches not only for the diagnosis, but also for the treatment of vascular thrombotic diseases.

Abstract
Cardiovascular disease is one of the major contributors to global disease burden. Atherosclerosis is an inflammatory process that involves the accumulation of lipids and fibrous elements in the large arteries, forming an atherosclerotic plaque. Rupture of unstable plaques leads to thrombosis that triggers life-threatening complications such as myocardial infarction. Current diagnostic methods are invasive as they require insertion of a catheter into the coronary artery. Molecular imaging techniques, such as magnetic resonance imaging, have been developed to image atherosclerotic plaques and thrombosis due to its high spatial resolution and safety. The sensitivity of magnetic resonance imaging can be improved with contrast agents, such as iron oxide nanoparticles. This review presents the most recent advances in atherosclerosis, thrombosis, and myocardial infarction molecular imaging using iron oxide-based nanoparticles. While some studies have shown their effectiveness, many are yet to undertake comprehensive testing of biocompatibility. There are still potential hazards to address and complications to diagnosis, therefore strategies for overcoming these challenges are required.

Abstract
Background Deep vein thrombosis (DVT) is an early postoperative complication. Thrombosis formation, which is potentially life-threatening, seriously affects the rehabilitation of patients after surgery. We aimed to establish a C57 mouse model of DVT and to examine the changes in the expression of Krüppel-like factor 15 (KLF15) and endothelial nitric oxide synthase (eNOS) in venous wall tissues, and we also investigated the regulatory relationship of KLF15 and eNOS in the thrombin-induced human umbilical vein endothelial cell (HUVEC) injury cell model. Methods The DVT model was established using the inferior vena cava (IVC) stenosis method. The expression levels of KLF15 and eNOS were analyzed using quantitative reverse transcription–polymerase chain reaction (qRT-PCR). In cell experiments, the expression of KLF15 and eNOS was analyzed in the model of thrombin-induced HUVEC injury with KLF15 siRNA. Results Compared to the control and sham-operated groups, KLF15 in the DVT group was upregulated, while eNOS was downregulated. The results of cell experiments revealed that KLF15 was downregulated in the thrombin+KLF15 siRNA group compared with the thrombin group. Meanwhile, eNOS was upregulated in the thrombin+KLF15 siRNA group compared with the thrombin group. These findings suggested that KLF15 regulated the expression of eNOS in the DVT model. Conclusions We successfully constructed a DVT mouse model. In the early stage of DVT formation, KLF15 regulated the expression and inhibited the antithrombotic effect of eNOS, resulting in thrombi formation.

Stable Low-Dose Oxygen Release Using H 2O 2/Perfluoropentane Phase-Change Nanoparticles with Low-Intensity Focused Ultrasound for Coronary Thrombolysis. ULTRASOUND IN MEDICINE & BIOLOGY 2020; 46:2765-2774.

Abstract
After the onset of myocardial infarction, extensive coronary thrombus and oxygen supply insufficiency lead to severe myocardial damage and heart failure. Recently, ultrasound-irradiated phase-change nanoparticles have been recognized for their cardiovascular thrombolysis potential. Therefore, we sought to establish a novel treatment method using hydrogen peroxide (H2O2)/perfluoropentane (PFP) phase-change nanoparticles with low-intensity focused ultrasound (LIFU) for the simulation of acute coronary thrombolysis and myocardial preservation. There were three groups in our study: Group A consisted of phosphate-buffered saline (PBS) as the blank control, group B consisted of SonoVue microbubbles and group C consisted of H2O2/PFP phase-change nanoparticles. The H2O2/PFP phase-change nanoparticles were prepared using a double-emulsification process. The in vitro experiments were conducted in an artificial circulatory system connected to an LIFU system and dissolved oxygen detector. Thrombolysis efficiency and oxygen release efficiency were compared among the groups. H2O2/PFP nanoparticles with 3% H2O2 (average size: 456.7 ± 31.2 nm, charge: -37.5 ± 5.22 mV) was the optimal selection in group C because of the stable loading capacity and stable low-dose oxygen release efficiency in the in vitro experiments. Thrombolytic weight loss and loss rates in group C (322.0 ± 40.8 mg, 54.8 ± 5.7%) were significantly higher than those in group A (36.2 ± 18.1 mg, 5.5 ± 2.5%) and group B (91.0 ± 11.9 mg, 14.3 ± 2.4%) (p < 0.01). The innovative method using H2O2/PFP phase-change nanoparticles with LIFU exhibited high thrombolytic efficiency and stable low-flow oxygen supply in the artificial circulatory system, providing a solid experimental foundation for the establishment of a novel treatment method for acute myocardial infarction.

Abstract
Although nanotechnology has shown great promise for treating multiple vascular diseases in recent years, simultaneous noninvasive detection and efficient dissolution of deep venous thrombosis (DVT) still remains challenging. In particular, long blockage areas and large thrombus thicknesses in DVT cause enormous difficulties for site-specific deep-seated thrombus theranostics. Therefore, based on the unique components of DVT, the novel concept of a thrombin-responsive full-thickness infiltration nonpharmaceutical nanoplatform for DVT theranostics is proposed here. The penetration depth is innovatively enhanced with efficient targeting and accumulation in the whole thrombi. Herein, we report a thrombin-responsive phase-transition liposome incorporating a liquid perfluoropentane (PFP) core and modified with two binding peptides, activatable cell-penetrating peptide (ACPP) and fibrin-binding ligand (FTP), which contribute to efficient liposome targeting and accumulation within the thrombi. This targeted nanoplatform is constructed to dig out the thrombus with the assistance of low-intensity focused ultrasound (LIFU), performing the destructive function of an excavator via an acoustic droplet vaporization effect (acting as a "nanoexcavator" system), which can activate and vaporize into microbubbles to enhance LIFU efficacy. The resulting microbubbles enable real-time monitoring of the therapeutic process with ultrasound imaging and high performance photoacoustic imaging after loading DIR. This non-invasive nonpharmaceutical thrombolytic strategy is an improvement over existing clinical methods without systemic side effects.

Stable cavitation using acoustic phase-change dodecafluoropentane nanoparticles for coronary micro-circulation thrombolysis. Int J Cardiol 2018; 272:1-6.

Abstract
BACKGROUND The thrombolysis in micro-circulation after acute myocardial infarction has been an unsolved issue, as elimination effect of acute thrombolysis and primary intervention were unsatisfied. Stable cavitation using acoustic phase-change nanoparticles may have potential for thrombolysis. Therefore, we sought to investigate a novel treatment method with dodecafluoropentane (DDFP) nanoparticles for rapid and effective thrombolysis in an in-vitro artificial vascular system, as a mimicking preparation of coronary circulation. METHODS To simulate thrombus embolism in coronary circulation, an in-vitro artificial vascular system was established with cavitation effect using DDFP nanoparticles. For PBS blank control (group A), SonoVue microbubbles (group B) and DDFP nanoparticles (group C), the durations for cavitation effect were recorded and the thrombolysis efficiency with low intensity focused ultrasound irradiation in the in-vitro vascular system were analyzed with weight loss and pathological changes of thrombus before and after thrombolysis. RESULTS The optimal conditions for acoustic cavitation effect were power of 6 W for 20 min by ultrasound irradiation at 37 °C. The weight loss and weight loss rates of thrombus in group C (189.4 ± 30.2 mg and 34.2 ± 5.7%) were higher than those in group A (30.2 ± 16.0 mg and 5.2 ± 2.1%) and group B (84.0 ± 20.4 mg and 14.6 ± 1.5%) (P < 0.01, all). The duration for cavitation effect in group C (32.8 ± 3.9 min) was also longer than those in group A (0.0 ± 0.0 min) and group B (5.3 ± 0.3 min) (P < 0.01, all). CONCLUSIONS By stable and sustaining cavitation in targeted area, DDFP nanoparticles with ultrasound irradiation have significantly increased the thrombolysis efficiency, which has provided a powerful experimental foundation for potential coronary thrombolysis.

Abstract
Deep venous thrombosis (DVT) affecting the extremities is a common clinical problem. Prompt imaging aids in rapid diagnosis and adequate treatment. While ultrasound (US) remains the workhorse of detection of extremity venous thrombosis, CT and MRI are commonly used as the problem-solving tools either to visualize the thrombosis in central veins like superior or inferior vena cava (IVC) or to test for the presence of complications like pulmonary embolism (PE). The cross-sectional modalities also offer improved visualization of venous collaterals. The purpose of this article is to review the established modalities used for characterization and diagnosis of DVT, and further explore promising innovations and recent advances in this field.

Abstract
Superparamagnetic nanoparticles have strong potential in biomedicine and have seen application as clinical magnetic resonance imaging (MRI) contrast agents, though their popularity has plummeted in recent years, due to low efficacy and safety concerns, including haemagglutination. Using an in situ procedure, we have prepared colloids of magnetite nanoparticles, exploiting the clinically approved anti-coagulant, heparin, as a templating stabiliser. These colloids, stable over several days, produce exceptionally strong MRI contrast capabilities particularly at low fields, as demonstrated by relaxometric investigations using nuclear magnetic resonance dispersion (NMRD) techniques and single field r1 and r2 relaxation measurements. This behaviour is due to interparticle interactions, enhanced by the templating effect of heparin, resulting in strong magnetic anisotropic behaviour which closely maps particle size. The nanocomposites have also reliably prevented protein-adsorption triggered thrombosis typical of non-stabilised nanoparticles, showing great potential for in vivo MRI diagnostics.

Abstract
PURPOSE To develop a three-dimensional (3D) noncontrast-enhanced (NCE) peripheral magnetic resonance venography (MRV) method and demonstrate its feasibility in vivo. METHODS The proposed MRV pulse sequence consisted of a velocity-selective (VS) inversion preparation module, inversion delay time (TI), fat inversion pulse, and 3D balanced steady-state free precession (bSSFP) dummy excitations and readout. The VS preparation module inverted arterial blood, which recovered close to zero magnetization during TI. The TI and the number of dummy excitations (Nnum ) were numerically optimized for maximizing vein-to-background contrast and tested in a healthy subject. The proposed MRV of the entire peripheral system, using four-station acquisition, was performed in six healthy subjects and three peripheral artery patients. RESULTS The numerical optimization yielded TI = 350 ms and Ndum = 40, which was supported by the largest vein contrast among the parameters chosen around the optima on in vivo venograms. Four-station peripheral MRV using the optimized parameters well visualized all major deep veins with high vein-to-background contrast. The relative vein contrast ratios were 0.80 ± 0.08, 0.75 ± 0.07, and 0.84 ± 0.06 against the arteries, muscle, and fat, respectively. CONCLUSION The proposed NCE MRV using VS preparation and transient bSSFP can generate high-contrast peripheral venograms directly with a single acquisition.

Abstract
Engineered nanoparticles are being increasingly produced for specific applications in medicine. Broad selections of nano-sized constructs have been developed for applications in diagnosis, imaging, and drug delivery. Nanoparticles as contrast agents enable conjugation with molecular markers which are essential for designing effective diagnostic and therapeutic strategies. Such investigations can also lead to a better understanding of disease mechanisms such as cancer-associated thrombosis which remains unpredictable with serious bleeding complications and high risk of death. Here we review the recent and current applications of engineered nanoparticles in diagnosis and therapeutic strategies, noting their toxicity in relation to specific markers as a target.

Abstract
Stroke is usually treated by systemic thrombolytic therapy if the patient presents within an appropriate time window. There is also widespread interest in the development of thrombolytic agents that can be used in cases of delayed presentation. Current agents that can be used in cases of delayed presentation of nerve damage by thrombus. Current systemic thrombolytic therapy is associated with adverse effects such as fibrinogenolysis and bleeding. In an attempt to increase the efficacy, safety, and specificity of thrombolytic therapy, a number of targeted thrombolytic agents have been studied in recent years. This review focuses on the concepts underlying targeted thrombolytic therapy and describes recent drug developments in this field.
