Hepatocellular carcinoma xenograft supports HCV replication:A mouse model for evaluating antivirals

World Journal of Gastroenterology 2011年第3期17卷 300-312页

AIM: To develop a hepatocellular carcinoma (HCC) xenograft model for studying hepatitis C virus (HCV) replication in a mice, and antiviral ***: We developed a stable S3-green fluorescence protein (GFP) cell line that replicated the GFP-tagged HCV sub-genomic RNA derived from a highly efficient JFH1 virus. S3-GFP replicon cell line was injected subcutaneously into γ-irradiated SCID mice. We showed that the S3-GFP replicon cell line formed human HCC xenografts in SCID mice. Cells were isolated from subcutaneous tumors and then serially passaged multiple times in SCID mice by culturing in growth medium supplemented with G-418. The mouse-adapted S3-GFP replicon cells were implanted subcutaneously and also into the liver of SCID mice via intrasplenic infusion to study the replication of HCV in the HCC xenografts. The tumor model was validated for antiviral testing after intraperitoneal injection of interferon-α (IFN-α). RESULTS: A highly tumorigenic S3-GFP replicon cell line was developed that formed subcutaneous tumors within 2 wk and diffuse liver metastasis within 4 wk in SCID mice. Replication of HCV in the subcutaneous and liver tumors was confirmed by cell colony assay, detection of the viral RNA by ribonuclease protection assay and real-time quantitative reverse transcription polymerase chain reaction. High-level replication of HCV sub-genomic RNA in the tumor could be visualized by GFP expression using fluorescence microscopy. IFN-α cleared HCV RNA replication in the subcutaneous tumors within 2 wk and 4 wk in the liver tumor model. CONCLUSION: A non-infectious mouse model allows us to study replication of HCV in subcutaneous and metastatic liver tumors. Clearance of HCV by IFN-α supports use of this model to test other anti-HCV drugs.

Comparative Analysis between Conventional PI, Fuzzy Logic and Artificial Neural Network Based Speed Controllers of Induction Motor with Considering Core Loss and Stray Load Loss

引用

Journal of Mechanics Engineering and Automation 2017年第1期7卷 50-57页

作者： Md. Rifat hazari Effat Jahan Mohammad Abdul Mannan Junji Tamura Department of Electrical and Electronic Engineering Kitami Institute of Technology 165 Koen-cho Kitami Hokkaido 090-8507 Japan Department of Electrical and Electronic Engineering American International University-Bangladesh Kemal Ataturk Avenue Banani Dhaka 1213 Bangladesh

Most of the controllers of IM （induction motor） for industrial applications have been designed based on PI controller without consideration of CL （core loss） and SLL （stray load loss）. To get the precise performances of torque as well as rotor speed and flux, the above mentioned losses should be considered. Conventional PI controller has overshoot effect at the transient period of the speed response curve. On the other hand, fuzzy logic and ANN （artificial neural network） based controllers can minimize the overshoot effect at the transient period because they have the abilities to deal with the nonlinear systems. In this paper, a comparative analysis is done between PI, fuzzy logic and ANN based speed controllers to find the suitable control strategy for IM with consideration of CL and SLL. The simulation analysis is done by using Matlab/Simulink software. The simulation results show that the fuzzy logic based speed controller gives better responses than ANN and conventional PI based speed controllers in terms of rotor speed, electromagnetic torque and rotor flux of IM.

Stabilization of Wind Farm by Using PMSG Based Wind Generator Taking Grid Codes into Consideration

引用

Journal of Power and Energy Engineering 2018年第11期6卷 40-52页

作者： Md. Rifat hazari Mohammad Abdul Mannan Atsushi Umemura Rion Takahashi Junji Tamura Department of Electrical and Electronic Engineering Kitami Institute of Technology (KIT) 165 Koen-cho Kitami Hokkaido 090-8507 Japan Department of Electrical and Electronic Engineering American International University-Bangladesh (AIUB) 408/1 Kuratoli Khilkhet Dhaka Bangladesh

This paper presents a new operational strategy for a large-scale wind farm (WF) which is composed of both fixed speed wind turbines with squirrel cage induction generators (FSWT-SCIGs) and variable speed wind turbines with permanent magnet synchronous generators (VSWT-PMSGs). FSWT-SCIGs suffer greatly from meeting the requirements of fault ride through (FRT), because they are largely dependent on reactive power. Integration of flexible ac transmission system (FACTS) devices is a solution to overcome that problem, though it definitely increases the overall cost. Therefore, in this paper, a new method is proposed to stabilize FSWT-SCIGs by using VSWT-PMSGs in a WF. This is achieved by injecting the reactive power to the grid during fault condition by controlling the grid side converter (GSC) of PMSG. The conventional proportional-integral (PI)-based cascaded controller is usually used for GSC which can inject small amount of reactive power during fault period. Thus, it cannot stabilize larger rating of SCIG. In this paper, a suitable fuzzy logic controller (FLC) is proposed in the cascaded controller of GSC of PMSG in order to increase reactive power injection and thus improve the FRT capability of WF during voltage dip situation due to severe network fault. To evaluate the proposed controller performance, simulation analyses are performed on a modified IEEE nine-bus system. Simulation results clearly show that the proposed method can be a cost-effective solution which can effectively stabilize the larger rating of SCIG compared to conventional PI based control strategy.

Eltrombopag Managed Severe Immune Thrombocytopenic Purpura in Pregnancy: A Case Report, Latifa Hospital, DHA, Dubai, UAE

引用

Open Journal of Obstetrics and Gynecology 2019年第7期9卷 991-996页

作者： Komal Sundeep hazari Atif Bashir E. Fazari Taghrid Gergawi Hasan Mohamed A.

Immune thrombocytopenic purpura (ITP) is an acquired autoimmune disorder, defined by a platelet count of less than 100 × 109/L, secondary to impaired production and immune destruction of platelets. Bleeding tendency is the main presentation of this condition. Clinical symptoms and investigations will confirm the diagnosis. Steroid is the first line of treatment. Although Rituximab and Thrombopoietin receptor agonists are useful second line agents in non-pregnant adults, the data about their role in pregnancy are still limited. We present the case of a 30 year old primigravida, who was a known case of chronic ITP since childhood;the course of her disease was fluctuating, for which oral steroids were used accordingly. She presented with gum bleeding and petechial rash with very low platelets count. She was sponsored by the Patient Support Program and was given Eltrombopag during the third trimester. She responded well to Eltrombopag with no noticeable side effects, neither to the mother nor to the baby so far. Eltrombopag has been assigned Category C by the Federal Drugs Agency (FDA) nevertheless there are no well controlled data in the literature about its role in pregnancy.
