Inhibition of Neovascularization to Simultaneously Ameliorate Graft-vs-Host Disease and Decrease Tumor Growth

Blood vessels are formed either by sprouting of resident tissue endothelial cells (angiogenesis) or by recruitment of bone marrow (BM)–derived circulating endothelial progenitor cells (EPCs, vasculogenesis). Neovascularization has been implicated in tumor growth and inflammation, but its roles in graft-vs-host disease (GVHD) and in tumors after allogeneic BM transplantation (allo...

Pegylated Interferon-α-2a plus Ribavirin for Treatment-Naive Asian Patients with Hepatitis C Virus Genotype 1 Infection: A Multicenter, Randomized Controlled Trial

Background. Comparable sustained virologic response (SVR) rates have been documented between Asian patients who received 24 weeks of pegylated interferon (IFN) plus ribavirin and white patients who received 48 weeks of combination therapy for hepatitis C virus genotype 1 (HCV-1) infection. Whether a 48-week course of combination therapy shows a better SVR rate than a 24-week...

Genetic associations with sporadic neuroendocrine tumor risk

Genetic risk factors for sporadic neuroendocrine tumors (NET) are poorly understood. We tested risk associations in patients with sporadic NET and non-cancer controls, using a custom array containing 1536 single-nucleotide polymorphisms (SNPs) in 355 candidate genes. We identified 18 SNPs associated with NET risk at a P -value <0.01 in a discovery set of 261 cases and 319...

Pegylated Interferon Alfa-2a Monotherapy for Hemodialysis Patients with Acute Hepatitis C

Background. Hemodialysis patients are at risk of hepatitis C virus (HCV) infection. However, little is known about the efficacy and safety of pegylated interferon (IFN) therapy for hemodialysis patients with acute hepatitis C.

A Large-scale genetic association study of esophageal adenocarcinoma risk

The incidence of esophageal adenocarcinoma (EA) has been increasing rapidly, particularly among white males, over the past few decades in the USA. However, the etiology of EA and the striking male predominance is not fully explained by known risk factors. To identify susceptible genes for EA risk, we conducted a pathway-based candidate gene association study on 335 Caucasian EA...

Short-hairpin RNAs delivered by lentiviral vector transduction trigger RIG-I-mediated IFN activation

Activation of the type I interferon (IFN) pathway by small interfering RNA (siRNA) is a major contributor to the off-target effects of RNA interference in mammalian cells. While IFN induction complicates gene function studies, immunostimulation by siRNAs may be beneficial in certain therapeutic settings. Various forms of siRNA, meeting different compositional and structural...

Association of hepatitis C virus infection and malnutrition–inflammation complex syndrome in maintenance hemodialysis patients

Patients undergoing maintenance hemodialysis (MHD) have a significantly higher prevalence of hepatitis C virus (HCV) infection and malnutrition–inflammation complex syndrome (MICS). In the present study of Taiwanese MHD patients, we determined the clinical characteristics and influence of HCV infection on MICS by calculation of the malnutrition–inflammation score (MIS).

Zinc Oxide Nanoparticles–Induced Intercellular Adhesion Molecule 1 Expression Requires Rac1/Cdc42, Mixed Lineage Kinase 3, and c-Jun N-Terminal Kinase Activation in Endothelial Cells

The explosive development of nanotechnology has caused an increase in unintended biohazards in humans and in the ecosystem. Similar to particulate matter, nanoparticles (NPs) are strongly correlated with the increase in incidences of cardiovascular diseases, yet the mechanisms behind this correlation remain unclear. Within the testing concentrations of 0.1–10 μg/ml, which did not...

Novel Split-Luciferase-Based Genetically Encoded Biosensors for Noninvasive Visualization of Rho GTPases

Rho family GTPases are critical regulators of many important cellular processes and the dysregulation of their activities is implicated in a variety of human diseases including oncogenesis and propagation of malignancy. The traditional methods, such as “pull-down” or two-hybrid procedures, are poorly suited to dynamically evaluate the activity of Rho GTPases, especially in living...

Loss of Carbamoyl Phosphate Synthetase I in Small-Intestinal Adenocarcinoma

Carbamoyl phosphate synthetase I (CPS1), normally found in hepatocytes and small-intestine (SI) enterocytes, is the antigen of Hep Par 1 antibody. Expression of CPS1 in invasive SI adenocarcinoma seems to be lost. We retrospectively collected 36 total specimens, which included 31 SI adenomas and 21 adenocarcinomas. We used 34 cases of duodenitis as a control group...

Hepatocyte Paraffin 1 Antigen as a Biomarker for Early Diagnosis of Barrett Esophagus

We evaluated hepatocyte paraffin 1 (HepPar1) antigen expression, a sensitive marker of small intestinal differentiation, in combination with morphologic features to demonstrate intestinal differentiation in cases equivocal for Barrett esophagus (BE). Clinicopathologic features and HepPar1 expression were recorded for 54 BE cases, 45 consistent with reflux esophagitis (RE) cases...

Construction of a full-length infectious bacterial artificial chromosome clone of duck enteritis virus vaccine strain

Background Duck enteritis virus (DEV) is the causative agent of duck viral enteritis, which causes an acute, contagious and lethal disease of many species of waterfowl within the order Anseriformes. In recent years, two laboratories have reported on the successful construction of DEV infectious clones in viral vectors to express exogenous genes. The clones obtained were either...

Gold Nanoparticles Increase Endothelial Paracellular Permeability by Altering Components of Endothelial Tight Junctions, and Increase Blood-Brain Barrier Permeability in Mice

Gold nanoparticles (Au-NPs) are being increasingly used as constituents in cosmetics, biosensors, bioimaging, photothermal therapy, and targeted drug delivery. This elevated exposure to Au-NPs poses systemic risks in humans, particularly risks associated with the biodistribution of Au-NPs and their potent interaction with biological barriers. We treated human umbilical vein...

Comparison of Electroacupuncture and Moxibustion for Relieving Visceral Hypersensitivity in Rats with Constipation-Predominant Irritable Bowel Syndrome

Aim. To compare whether there is different effect between electroacupuncture (EA) and moxibustion (Mox) on visceral hypersensitivity (their analgesic effects) in constipation-predominant irritable bowel syndrome (C-IBS). Methods. EA at 1 mA and 3 mA and Mox at 43°C and 46°C were applied to the Shangjuxu (ST37, bilateral) acupoint in rats with C-IBS and normal rats. An abdominal...

Identification of a novel de novo GATA3 mutation in a patient with HDR syndrome

We describe the case of a 21-year-old male with hypocalcaemia, hyperphosphataemia, recurrent limb twitch, deafness, proteinuria, increased serum creatinine and urea nitrogen levels, and shrinkage of both kidneys. Brain computed tomography showed intracranial calcifications. The patient was diagnosed with hypoparathyroidism, sensorineural deafness and renal dysplasia (HDR...
