background treatment with peginterferon alpha-2b plus ribavirin is the current standard therapy for chronic hepatitis c (chc). however, many host related and viral parameters are associated with different outcomes of combination therapy. objectives the aim of this study was to develop an artificial neural network (ann) model to predetermine individual responses to therapy based on patient’s dem...

Background: Viral infections such as Epstein-Barr virus and Herpes simplex virus may play a role in the pathogenesis of Behçet’s disease (BD). Interferons (INF) are natural defense mechanisms against viruses and inhibit their activities by enhancing major histocompatibility complex class I and cytokine expression. This study evaluated the efficacy of INF-α-2b on mucocutaneous lesions of BD. Met...

In the [(13)C]-octanoate breath test, two popular parameters have been used to quantify gastric emptying rates, namely the time to the maximal [(13)CO(2)] excretion (T(max)) and the time to the half-[(13)CO(2)] recovery (T(1/2b)). Although each of T(max) and T(1/2b) is closely correlated with the scintigraphic half-emptying time, the two parameters occasionally indicate different judgments on a...

The aim of this study was to investigate the effect of the genetic background on the phenobarbital inducibility of cytochrome P-450 2b-9, cytochrome P-450 2b-10 and aldehyde dehydrogenase type 2 mRNAs in mice. We analysed the basal expression and the phenobarbital inducibility of both cytochrome P-450 mRNAs by semi-quantitative specific reverse transcription-PCR analyses in five inbred mouse st...

BACKGROUND This article addresses the treatment of VTE disease. METHODS We generated strong (Grade 1) and weak (Grade 2) recommendations based on high-quality (Grade A), moderate-quality (Grade B), and low-quality (Grade C) evidence. RESULTS For acute DVT or pulmonary embolism (PE), we recommend initial parenteral anticoagulant therapy (Grade 1B) or anticoagulation with rivaroxaban. We sugg...

Arsenic as a toxic metalloid has been found to have potential carcinogenic effects of humans. However, pulmonary toxicity has not been fully elucidated. The purpose of this experiment is to test and observe the degree of toxicity of various concentrations of sodium arsenite (NaAsO2) on human lung epithelial cells (BEAS-2B cell line). In this experiment, BEAS-2B cells were plated and grown accor...

Drug-induced valvular heart disease (VHD) is a serious side effect of a few medications, including some that are on the market. Pharmacological studies of VHD-associated medications (e.g., fenfluramine, pergolide, methysergide, and cabergoline) have revealed that they and/or their metabolites are potent 5-hydroxytryptamine(2B) (5-HT(2B)) receptor agonists. We have shown that activation of 5-HT(...

Adenosine is an extracellular signaling molecule that is generated in response to cell injury where it orchestrates tissue protection and repair. Whereas adenosine is best known for promoting anti-inflammatory activities during acute injury responses, prolonged elevations can enhance destructive tissue remodeling processes associated with chronic disease states. The generation of adenosine and ...

Viroporins are a family of low-molecular-weight hydrophobic transmembrane proteins that are encoded by various animal viruses. Viroporins form transmembrane pores in host cells via oligomerization, thereby destroying cellular homeostasis and inducing cytopathy for virus replication and virion release. Among the Picornaviridae family of viruses, the 2B protein encoded by enteroviruses is well un...

The human adenosine A(2B) receptor belongs to class A G protein-coupled receptors (GPCRs). In our previous work, constitutively active mutant (CAM) human adenosine A(2B) receptors were identified from a random mutation bank. In the current study, three known A(2B) receptor antagonists, 4-{2-[7-amino-2-(2-furyl)[1,2,4]triazolo-[2,3-a][1,3,5]triazin-5-yl-amino]ethyl}phenol (ZM241385), 8-cyclopent...
