BACKGROUND Coxsackievirus B3 is an important infectious agent of viral myocarditis, pancreatitis and aseptic meningitis, but there are no specific antiviral therapeutic reagents in clinical use. RNA interference-based technology has been developed to prevent the viral infection. METHODS To evaluate the impact of RNA interference on viral replication, cytopathogenicity and animal survival, sho...

Chronic cocaine induces high expression of the brain-specific Neural-Zinc-Finger transcription factor-2b (NZF-2b/7ZFMyt1), particularly in the mesolimbic dopaminergic pathway, resulting in a 11-fold increase in NZF-2b/7ZFMyt1 expression in the Nucleus Accumbens (NAc). Overexpression of this gene in the NAc with a NZF-2b/7ZFMyt1-expressing lentivirus resulted in >55% decrease in locomotor activi...

Previous studies in cultured, polarized Madin-Darby canine kidney II (MDCKII) renal epithelial cells have demonstrated that the apical steady-state localization and delivery of the A(1) adenosine receptor is modified by disruption of the microtubule network with colchicine, whereas the basolateral localization and trafficking of the alpha(2)-adrenergic receptors (alpha(2)AR) are not; instead, t...

Neural circuit assembly requires selection of specific cell fates, axonal trajectories, and synaptic targets. By analyzing the function of a secreted semaphorin, Sema-2b, in Drosophila olfactory receptor neuron (ORN) development, we identified multiple molecular and cellular mechanisms that link these events. Notch signaling limits Sema-2b expression to ventromedial ORN classes, within which Se...

PURPOSE EURAMOS-1, an international randomized controlled trial, investigated maintenance therapy with pegylated interferon alfa-2b (IFN-α-2b) in patients whose osteosarcoma showed good histologic response (good response) to induction chemotherapy. PATIENTS AND METHODS At diagnosis, patients age ≤ 40 years with resectable high-grade osteosarcoma were registered. Eligibility after surgery for ...

results overall, 3 (15%) subjects achieved svr, 10 cases (50%) relapsed after treatment cessation and 7 (35%) patients did not clear hdv during the treatment. conclusions hdv coinfection with hbv had very low response rate to high doses and long durations of ifn α-2b therapy. objectives we aimed to determine the efficacy of ifn α-2b therapy in patients with hbv/hdv coinfection. patients and met...

background: the aim of this study was to evaluate the effectiveness of monotherapy with interferon alpha-2b and combination therapy with interferon alpha-2b plus ribavirin on chronic hepatitis c infection in thalassaemic patients. methods: in parallel group randomized, double blind, controlled trial, 32 thalassaemic patients with chronic hepatitis c infection completed the study. in a random fa...

BACKGROUND: Canine Parvovirus (CPV) is one of the major causes of fatal gastroenteritis in young dogs. After emergence of CPV-2, two new variants were reported and named CPV-2a and CPV-2b. In 2001 the newest variant was reported and named CPV-2c. The difference between CPV strains is related to amino acid changes in viral capsid protein (VP2). OBJECTIVES: The aim of the present study was geneti...
