OBJECTIVES We hypothesized that neurohormonal activity contributes to the initiation of sustained ventricular tachycardia (VT) as reflected in indices of heart rate variability (HRV). BACKGROUND Autonomic nervous system activity participates in experimental arrhythmias but clinical studies have been inconsistent. METHODS Holter electrocardiograms from 53 patients with VT were analyzed. Hear...
Optimization problems subject to constraints given by partial differential equations (PDEs) with additional constraints on the control and/or state variables belong to the most challenging problem classes in natural sciences, engineering, and economics. Due to the complexities of the PDEs and the requirement for rapid solution pose significant challenges for the computational scientists. A part...
مقدمه: نقایص مرتبط با عملکرد ناقل های ژنی اعم از ناقل های ویروسی و غیر ویروسی باعث شده است محققان برای دستیابی به ناقل یا ناقل های ژنی ایده آل به تحقیقات خود ادامه دهند. فاژها به خاطر داشتن یکسری مزیت ها همچون حفاظت از ژن خارجی، عدم ایمنی زایی و پایداری در شرایط مختلف، به عنوان گزینه ای مطلوب برای انتقال ژن مطرح شده اند. هدف از این پژوهش، دستیابی به یک سازه فاژی و ارزیابی پتانسیل آن جهت انتقال ...
The U.S. Environmental Protection Agency’s (EPA) Water Laboratory Alliance relies on the Centers for Disease Control and Prevention’s ultrafiltration-based Water Processing Procedure (WPP) for concentration of biosafety level 3 (BSL-3) agents from 10 L to 100 L of drinking water. The WPP requires comprehensive training and practice to maintain proficiency, resulting in a critical need for quali...
This work presents the molecular simulation program ms2 that is designed for the calculation of thermodynamic properties of bulk fluids in equilibrium consisting of small electro-neutral molecules. ms2 features the two main molecular simulation techniques, molecular dynamics (MD) and Monte-Carlo. It supports the calculation of vapor-liquid equilibria of pure fluids and multi-component mixtures ...
Current treatments for hepatocellular carcinoma (HCC) have shown inadequate. MicroRNA-122 (miR-122) mediated RNA interference brings new prospects. A safe, efficient miRNA delivery system is an indispensable assurance. Previously, we developed an MS2 bacteriophage virus-like particle (VLP)-based microRNA delivery system crosslinked with the HIV TAT peptide, which served as an effective inhibito...
Single cell imaging studies suggest that transcription is not continuous and occurs as discrete pulses of gene activity. To study mechanisms by which retroviral transgenes can transcribe to high levels, we used the MS2 system to visualize transcriptional dynamics of high expressing proviral integration sites in embryonic stem (ES) cells. We established two ES cell lines each bearing a single co...
