Advances in Endoscopic Eradication Therapy for Barrett's Esophagus associated neoplasia have resulted in a significant paradigm shift in diagnosis and management of this complex disease. A robust body of literature critically evaluating outcomes of resection and ablative strategies has allowed gastroenterologists to make quality, evidence based decisions for their patients. Despite this progress, there are still many unanswered questions and challenges that remain. Ultimately, identification of a cost-effective screening modality, biomarkers for risk stratification, and strides to eliminate post surveillance endoscopy after EET are essential to reach our long term goal for eradication of esophageal adenocarcinoma...

Endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are the mainstays of interventional endoscopic practice. EUS occupies a central role in the diagnosis of pancreatobiliary neoplasms and offers a platform for a wide range of direct tumor therapies. Initial steps have demonstrated the feasibility of such applications in animal models and pilot studies. Larger clinical trials and incorporation of EUS-based therapies into cooperative cancer studies might demonstrate an impact in the clinical prognosis of patients with pancreatic cancer...

Radiofrequency ablation (RFA) is considered to be a potentially curative therapy for hepatocellular carcinoma (HCC). However, insufficient RFA (IRFA) can promote rapid progression of the residual tumor. The mechanisms underlying IRFA-induced tumor promotion remain poorly understood. In the present study, we have established a subcutaneous xenograft mouse model and monitored the location and extent of IRFA by dual monitoring with ultrasonography and a thermal imager. For the first time, we provide evidence of the activation of autophagic pathways in mice exposed to IRFA...

Tumor invasion is a critical first step in the organismic dissemination of cancer cells and the formation of metastasis in distant organs, the most important prognostic factor and the actual cause of death in most of the cancer patients. We report here that the cell surface protein podoplanin (PDPN), a potent inducer of cancer cell invasion, is conspicuously expressed by the invasive front of squamous cell carcinomas (SCC) of the cervix in patients and in the transgenic HPV/E2 mouse model of cervical cancer...

Endoplasmic reticulum (ER) stress is activated in non-alcoholic fatty liver disease (NAFLD), raising the possibility that ER stress-dependent metabolic dysfunction, inflammation and cell death underlie the transition from steatosis to steatohepatitis (NASH). Bax inhibitor-1 (BI-1), a negative regulator of the ER stress sensor IRE1α, has yet to be explored in NAFLD as a hepatoprotective agent. We hypothesized that the genetic ablation of BI-1 would render the liver vulnerable to NASH due to unrestrained IRE1α signaling...

The compensatory proliferation of insulin-producing β cells is critical to maintaining glucose homeostasis at the early stage of type 2 diabetes. Failure of β cells to proliferate results in hyperglycemia and insulin dependence in patients. To understand the effect of the interplay between β cell compensation and lipid metabolism upon obesity and peripheral insulin resistance, we eliminated LDL receptor-related protein 1 (LRP1), a pleiotropic mediator of cholesterol, insulin, energy metabolism, and other cellular processes, in β cells...

Squamous cell carcinoma (SCC) of the head and neck can be treated with a combination of modalities. There is an esthetic and functional compromise with midfacial defects secondary to ablative surgery and adjuvant therapies for SCC. Osteoradionecrosis, tissue contracture, and trismus, are all negative side effects of treatment and can impact a patient's function and possibly their nutrition. In this report, we describe a procedure for fabrication of a prosthesis that provides cosmetic improvement and labial competence to maintain caloric intake...

INTRODUCTION: Recent evidence indicates that early removal of eschar by tangential debridement can promote healing. Laser debridement can be used for debridement of areas that prove challenging for debridement using tangential excision. In particular, irradiation with an ArF excimer laser ablates desiccated eschar and is self-terminating, preserving hydrated or viable tissue. METHODS: Thermal burns were created on the flanks of two outbred, female Yorkshire pigs using aluminum bars heated to 70°C and applied for different lengths of time...

This report describes the use of laser ablation for treatment of chronic enterocutaneous fistulae (ECFs) after failure of conservative therapy. Three patients underwent laser ablation for treatment of 8 ECFs. Mean duration of fistula patency was 28 months with mean fistula output of 134 mL/day. The initial technical success was 100% with no major or minor complications. Three ECFs required repeat treatment. At mean follow-up of 53 days, 7 of the fistulae were occluded. One fistula showed a markedly reduced output of 10 mL/day...

Laser systems are widely used in mass spectrometry as sample probes and ionization sources. Mid-infrared lasers are particularly suitable for analysis of high water content samples such as animal and plant tissues, using water as a resonantly excited sacrificial matrix. Commercially available mid-IR lasers have historically been bulky and expensive due to cooling requirements. This work presents a novel air-cooled miniature mid-IR laser with adjustable burst-mode output and details an evaluation of its performance for mass spectrometry imaging...

Zhen-Guo Pan, Xu-Sheng An
SARM1 (Sterile alpha and armadillo motif-containing protein 1) is the recently identified TIR domain-containing cytosolic protein, which is involved in toll-like receptors (TLRs) signaling transduction. In the present study, the role of SARM1 in high fat diet (HFD)-induced non-alcoholic fatty liver disease (NAFLD) progression was explored. We found that SARM1 was expressed highly in fatty liver. And SARM1-knockout (KO) reduced steatohepatitis and metabolic disorders induced by HFD. SARM1-deletion decreased aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in HFD-fed mice...

Ventricular arrhythmias are responsible for hundreds of thousands of deaths every year. Catheter ablation of ventricular tachycardia (VT) is an essential component of the management of these life-threatening arrhythmias. However, in many patients, despite medical and interventional therapy, VT recurs. Further, some VT substrates (mid-myocardial, left ventricular summit, intra-septal) are not easily targeted, due to limitations of currently available technology. In certain clinical settings, ventricular fibrillation (VF) episodes that have premature ventricular contraction (PVC) triggers can also be targeted with catheter ablation...
