In this work, pulsed laser ablation in liquid (PLAL) technique was applied to synthesize colloidal nanoparticles of zirconium oxide (ZrO2) in three different aqueous media (de-ionized water, ethanol and acetone). The structure, morphology, composition and optical properties of the synthesized nanoparticles were characterized by XRD, SEM, TEM, XPS, UV-Vis spectrophotometer and FT-IR analysis respectively. The structural analysis by XRD reveals the formation of mixture of monoclinic and tetragonal phases of nanocrystalline zirconia...

The pregnane X receptor (PXR, NR1I2) is a xenobiotic-sensing nuclear receptor that defends against toxic agents. We have shown that PXR promotes chronic ethanol (EtOH)-induced steatosis. Therefore, we examined the role of PXR in binge EtOH-induced hepatotoxicity. Male wild type (WT) and Pxr-null mice were orally administered three binge doses of EtOH (4.5 g/kg, every 12 hours) and euthanized four hours after the final dose. Pxr-null mice displayed higher basal mRNA levels of hepatic lipogenic transcription factor sterol regulatory element binding protein 1c (Srebp-1c) and its target stearoyl-CoA desaturase 1 (Scd1) and the lipid peroxide detoxifying aldo-keto reductase 1b7 (Akr1b7) and higher protein levels of EtOH-metabolizing alcohol dehydrogenase 1 (ADH1)...

OBJECTIVE: No standardized therapeutic algorithm or embolic agent of choice has yet been identified for management of congenital peripheral venous malformations (VMs). Treatment options and reported outcomes therefore vary widely. Herein, we present an institution-wide algorithm for management of symptomatic congenital peripheral VMs using a single embolotherapeutic modality. METHODS: During 36 months, patients with symptomatic congenital peripheral VMs underwent contrast-enhanced magnetic resonance imaging...

Sang Hyub Lee
The decision of the appropriate treatment for pancreatic cystic lesions (PCLs) is becoming increasingly important as the number of incidentally found PCLs increases. A range of modalities have been attempted because there has been an increasing demand for minimally invasive treatment for PCLs due to the large burden of a surgical resection. Endoscopic treatment using endoscopic ultrasonography (EUS), a representative of minimally invasive therapy, can be categorized into two types: ablation therapy by the injection of drugs and topical thermal coagulative therapy through the high topical energy...

BACKGROUND: Understanding the characteristics of the middle cervical sympathetic ganglion (MCSG) may minimize procedure-related complications and maximize efficacy during surgery or ultrasound (US)-guided procedures. The location and detection rate of the MCSG were variable in small population studies. Therefore, a large population study or meta-analysis could give more information about the MCSG. OBJECTIVES: We aim to review the published literature and evaluate the anatomical features of the MCSG, including the detection rate, location, size, and a normal variation, and to review the clinical relevance of MCSG for procedures including, US-guided ganglion block, ethanol ablation (EA), or radiofrequency ablation (RFA)...

BACKGROUND: Sarcomatoid hepatocellular carcinoma (SHC) is a rare malignant hepatic tumor. Recurrent interventional therapies such as transcatheter arterial chemo-embolization (TACE), radiofrequency ablation (RFA), and percutaneous ethanol injection have been reported previously utilized in a majority of SHC cases. To date, the exact pathogenic mechanisms underlying sarcomatoid transformation of hepatocellular carcinoma (HCC) remain unknown. CASE PRESENTATION: In this study, we report a 68-year-old female SHC patient admitted to our hospital due to discrete abdominal distention for more than 20 days...

A carbon screen-printed electrode was modified with copper nanoparticles from their dispersion obtained via pulsed laser ablation of a copper target in ethanol. The modified electrode exhibited activity in ascorbic acid electrochemical oxidation, giving an anodic current peak on voltammograms. Linear sweep and cyclic voltammetry have shown a linear dependence of the signal (both peak height and peak area) on the ascorbic acid concentration. The linear range from 1 to 250 μM of ascorbic acid was studied, and the detection limit was experimentally found to be 0...

REVIEW
Sundeep Lakhtakia
Pancreatic neuroendocrine tumors (PNETs) are increasingly being detected, though usually as incidental findings. Majority of the PNETs are non-functional and surgical resection is the standard of care for most of them. However, in patients with small PNETs localized within the pancreas, who are unfit or unwilling for surgery, alternate methods of treatment are needed. Direct methods of ablation of PNETs, using either ethanol injection or radiofrequency ablation (RFA), are emerging as effective methods. The limited literature available as case reports or case series on endoscopic ultrasound (EUS)-guided local ablation using either ethanol or RFA has demonstrated safety and efficacy along with short- to medium-term sustained relief...

Insulinomas are predominantly benign (~90%), pancreatic neuroendocrine tumours characterised by hyperinsulinaemic hypoglycaemia. They usually present as a small (<2cm), well demarcated, solitary nodule that can arise in any part of the organ. Treatment of sporadic insulinomas is generally aimed at curative surgical resection with special consideration in genetic syndromes. Patients with significant hypoglycaemia can pose a difficult management challenge. In isolated cases where the patient is not medically fit for surgery or with metastatic spread, other treatment options are employed...

Ependymal cilia protrude into the central canal of the brain ventricles and spinal cord to circulate the cerebral spinal fluid (CSF). Ependymal cilia dysfunction can hinder the movement of CSF leading to an abnormal accumulation of CSF within the brain known as hydrocephalus. Although the etiology of hydrocephalus was studied before, the effects of ethanol ingestion on ependymal cilia function have not been investigated in vivo. Here, we report three distinct types of ependymal cilia, type-I, type-II and type-III classified based upon their beating frequency, their beating angle, and their distinct localization within the mouse brain-lateral ventricle...

Key methodological assumptions regarding the degree of natural variability and influence of sample handling and storage of elasmobranch vertebral chemistry were assessed using laser-ablation inductively coupled plasma mass spectrometry. Vertebral chemistry of juvenile blacktip sharks Carcharhinus limbatus was examined to identify whether differences existed among different regions of the vertebral column, between thoracic vertebrae of individual fish or within individual vertebrae. Additionally, the effects of bleach exposure and storage in ethanol on vertebral chemistry were compared...

At present, surgical septal myectomy is regarded as the "gold standard" treatment for most patients with obstructive hypertrophic cardiomyopathy (HCM) and drug-refractory symptoms. However, the best results are obtained by those surgeons who have extensive experience with this operation at a small number of referral centers. In the mid-1990s, percutaneous alcohol septal ablation was introduced as an alternative to myectomy to reduce LV outflow gradient and heart failure symptoms in patients with obstructive HCM...
