It is sometimes used in conjunction with but is distinct from INTERVENTIONAL ULTRASONOGRAPHY.Tachycardia, Atrioventricular Nodal Reentry: Abnormally rapid heartbeats caused by reentry of atrial impulse into the dual (fast and slow) pathways of ATRIOVENTRICULAR NODE. The common type involves a blocked atrial impulse in the slow pathway which reenters the fast pathway in a retrograde direction and simultaneously conducts to the atria and the ventricles leading to rapid HEART RATE of 150-250 beats per minute.Body Surface Potential Mapping: Recording of regional electrophysiological information by analysis of surface potentials to give a complete picture of the effects of the currents from the heart on the body surface. It has been applied to the diagnosis of old inferior myocardial infarction, localization of the bypass pathway in Wolff-Parkinson-White syndrome, recognition of ventricular hypertrophy, estimation of the size of a myocardial infarct, and the effects of different interventions designed to reduce infarct size. The limiting factor at present is the complexity of the recording and analysis, which requires 100 or more electrodes, sophisticated instrumentation, and dedicated personnel.

Non-thermal ablation of rabbit liver VX2 tumor by pulsed high intensity focused ultrasound with ultrasound contrast agent: Pathological characteristics. (4/191)

AIM: To investigate the pathological characteristics of non-thermal damage induced by pulsed high intensity focused ultrasound (PHIFU) combined with ultrasound contrast agent (UCA), SonoVue (Bracco SpA, Milan, Italy) in rabbit liver VX2 tumor. METHODS: Liver VX2 tumor models were established in 20 rabbits, which were divided randomly into PHIFU combined with ultrasound contrast agent group (PHIFU + UCA group) and sham group. In the PHIFU + UCA group, 0.2 mL of SonoVue was injected intravenously into the tumor, followed by ultrasound exposure of I(SP) 5900 W/cm(2). The rabbits were sacrificed one day after ultrasound exposure. Specimens of the exposed tumor tissues were obtained and observed pathologically under light microscope and transmission electron microscope. The remaining tumor tissues were sent for 2,3,5-Triphenyltetrazolium chloride (TTC) staining. RESULTS: Before TTC staining, tumor tissues in both the sham and the PHIFU + UCA groups resembled gray fish meat. After TTC staining, the tumor tissues were uniformly stained red, with a clear boundary between tumor tissue and normal tissue. Histological examination showed signs of tumor cell injury in PHIFU + UCA group, with cytoplasmic vacuoles of various sizes, chromatin margination and karyopyknosis. Electron microscopic examination revealed tumor cell volume reduction, karyopyknosis, chromatin margination, intercellular space widening, the presence of high electron-density apoptotic bodies and vacuoles in cytoplasm. CONCLUSION: The non-thermal effects of PHIFU combined with UCA can be used to ablate rabbit liver VX2 tumors.  (+info)

10. Multilateral action necessarily demands an organizational framework. The United Nations, in particular, is and should remain the primary venue for cooperation and coordination between nations, though regional forums have an important role to play in this regard as well. The United Nations is an imperfect institution, and many ideas for institutional reform have been mooted. Institutions, however, reflect the capacity of their members to work together. No state can expect that its policies will be accepted at all times by the community of nations. The UNs achievements are the result of the dedication of its major members, and its failures are due to lack of support by member states. Institutional changes in the United Nations are very unlikely to occur even in the medium term - the urgent and central task of todays leaders must be to work effectively with the organizations that exist and the tools at hand. The vital role of the Security Council remains central to todays international ...

A new method for the ablation of undesirable tissue such as cells of a cancerous or non-cancerous tumor is disclosed. It involves the placement of electrodes into or near the vicinity of the undesirable tissue through the application of electrical pulses causing irreversible electroporation of the cells throughout the entire area of the undesirable tissue. The electric pulses irreversibly permeate the cell membranes, thereby invoking cell death. The irreversibly permeabilized cells are left in situ and are removed by the body immune system. The amount of tissue ablation achievable through the use of irreversible electroporation without inducing thermal damage is considerable.
To report on the first short-term oncologic outcomes of percutaneous irreversible electroporation for small renal masses.Patients with cT1a renal masses treated with irreversible electroporation from April 2013 through December 2016 were reviewed.
Irreversible electroporation is a minimally invasive technique for the non-thermal destruction of cells in a targeted volume of tissue, using brief electric pulses, (~100 µs long) delivered through electrodes placed into or around the targeted region. These electric pulses destabilize the integrity of the cell membrane, resulting in the creation of nanoscale defects that increase a cells permeability to exchange with its environment. When the energy of the pulses is high enough, the cell cannot recover from these effects and dies in a non-thermal manner that does not damage neighboring structures, including the extracellular matrix. IRE has been shown to spare the major vasculature, myelin sheaths, and other supporting tissues, permitting its use in proximity to these vital structures. This technique has been proposed to be harnessed as an advantageous non-thermal focal ablation technique for diseased tissues, including tumors. IRE electric pulses may be delivered through small (ø ≈ 1 mm) ...

PurposeNumerical simulations are used for treatment planning in clinical applications of irreversible electroporation (IRE) to determine ablation size and shape. To assess the reliability of simulations for treatment planning, we compared simulation results with empiric outcomes of renal IRE using computed tomography (CT) and histology in an animal model.MethodsThe ablation size and shape for six different IRE parameter sets (70-90 pulses, 2,000-2,700 V, 70-100 µs) for monopolar and bipolar electrodes was simulated using a numerical model. Employing these treatment parameters, 35 CT-guided IRE ablations were created in both kidneys of six pigs and followed up with CT immediately and after 24 h. Histopathology was analyzed from postablation day 1.ResultsAblation zones on CT measured 81 ± 18 % (day 0, p ≤ 0.05) and 115 ± 18 % (day 1, p ≤ 0.09) of the simulated size for monopolar electrodes, and 190 ± 33 % (day 0, p ≤ 0.001) and 234 ± 12 % (day 1, p ≤ 0.0001) for bipolar electrodes. ...

Exposing a biological cell to an electric field results in structural changes in the cell plasma membrane. If the electric field is sufficiently high, the changes in the trans-membrane voltage cause the membrane to become permeable to molecules which otherwise cannot cross it. The described phenomenon is termed electroporation [1] and can be either reversible or irreversible. If the electric field at given pulse characteristics exceeds the reversible electroporation threshold, the cell eventually returns to its normal state and survives; this is called reversible electroporation. However, if the electric field exceeds the threshold of irreversible electroporation or the cell is exposed to the electric field too long, the changes in the membrane lead to irreversible electroporation (IRE) characterized by cell death.. Both reversible and irreversible electroporation have found their use in treatment of tumors [2]. Combination of reversible electroporation and cytotoxic drugs used in chemotherapy ...

The present study was designed to evaluate the efficacy and safety of the intracoronary ethanol ablation technique in patients with paroxysmal ventricular tachycardia related to prior myocardial infarction. Twenty-three patients with sustained monomorphic ventricular tachycardia that was refractory to conventional antiarrhythmic drug therapy were prospectively studied. After induction of ventricular tachycardia by programmed electrical stimulation, the response of the arrhythmia to the infusion of radiographic contrast medium or saline solution into the ostia of the native coronary arteries and coronary artery bypass grafts was assessed. If ventricular tachycardia was reliably interrupted by injections into the proximal coronary artery or bypass graft, the vessel was cannulated with a steerable guide wire
A microwave ablation instrument including a transmission line having a first conductor and a second conductor suitable for the transmission of microwave energy. A horn antenna device is mounted to the end of the transmission line, and include an outer conductor and an inner conductor. The outer conductor of the horn antenna is electrically coupled to the second conductor of the transmission line, and includes a peripherally extending interior wall flaring outwardly to define a recess therein. The inner conductor of the horn antenna is electrically coupled to the first conductor of the transmission line and terminates in the outer conductor recess. The inner conductor and the outer conductor cooperate to emit an electromagnetic field sufficiently strong to cause tissue ablation in a direction generally away from the flared interior wall of the outer conductor.
PURPOSE: To evaluate preliminary outcomes after microwave ablation (MWA) of hepatocellular carcinoma (HCC) up to 5 cm and to determine the influence of tumor size. MATERIALS AND METHODS: Electronic records were searched for HCC and MWA. Between January 2011 and September 2014, 173 HCCs up to 5 cm were treated by MWA in 129 consecutive patients (89 men, 40 women; mean age, 66.9 y ± 9.5). Tumor characteristics related to local tumor progression and primary and secondary treatment efficacy were evaluated by univariate analysis. Outcomes were compared between tumors ≤ 3 cm and tumors | 3 cm. RESULTS: Technical success, primary efficacy, and secondary efficacy were 96.5%, 99.4%, and 94.2% at a mean follow-up period of 11.8 months ± 9.8 (range, 0.8-40.6 mo). Analysis of tumor characteristics showed no significant risk factor for local tumor progression, including subcapsular location (P = .176), tumor size (P = .402), and perivascular tumor location (P = .323). The 1-year and 2-year secondary or overall

Trial Design. Pancreatic cancer resectability is defined by the absence of metastases and only limited invasion of arteries (SMA, common hepatic artery, celiac trunk) and veins (superior mesenteric vein / portal vein) (Katz et al. 2013, Ann Surg Oncol 20:2787). Only Stage III pancreatic cancer (AJCC - TNM 7th edition) will be enrolled in the study. All cases will be reviewed at the multidisciplinary meeting to confirm eligibility. After obtaining their informed consent patients will receive 4 cycles of FOLFIRINOX chemotherapy. Following reassessment, patients without progression will proceed to local treatment. Diagnostic laparoscopy will be performed to exclude distant metastases. Unresectable tumors up to 4cm will be randomized between stereotactic body radiotherapy (SBRT) (Arm A) versus irreversible electroporation (IRE) (Arm B). Tumors larger than 4cm will be randomized to chemo-radiation (Intensity modulated radiation therapy: 28 × 2Gy = 56 Gy to the primary tumor and metastatic lymph ...
Cellulose nanocrystals (CNCs) have been studied widely for a variety of applications. Despite their advantages, investigations of their abilities in the biomedical field have not been explored. The goal of this project is to delve into the potential uses of CNCs in detection, targeted drug delivery, and potentiation of irreversible electroporation (IRE)-induced cell death in folate receptor (FR)-positive cancers. To accomplish this task we have prepared stable and reproducible CNCs from wood pulp via sulfuric acid hydrolysis. Furthermore, we have functionalized the surface of these nanoparticles and conjugated them with the targeting ligand folic acid (FA) and the fluorescent imaging agent fluorescein-5\-isothiocyanate (FITC) to create FITC-CNC-FA; CNCs have also been conjugated with doxorubicin (DOX), a potent chemotherapeutic (DOX-ALAL-CNC-FA). We have determined FITC-CNC-FA\s and DOX-ALAL-CNC-FA\s ability to specifically target FR-positive cancer cells in vitro; meanwhile non-targeted CNCs ...
