Strategic Study of Chinese Academy of Engineering 2007, Volume 9, Issue 5, Pages 72-76

Abstract:

In this study, an effective control method and strategy based on fuzzy neural network has been developed for gas injection pressure accurate control in gas-assisted injection. A fuzzy neural network controller with five layers and its control algorithm are established. The learning ability of neural network is used to optimize the rules of the fuzzy logic so as to improve the adaptability of system. The simulation of the system capability and three segmental injected pressure control are carried out under the environment of MATLAB and the results show that this theoretic model is feasible, and the control system has good characteristics and control action.

Molecular aspects of MERS-CoV

Al-Ahmed, Jaffar A. Al-Tawfiq

Frontiers of Medicine 2017, Volume 11, Issue 3, Pages 365-377 doi: 10.1007/s11684-017-0521-z

Abstract:

Middle East respiratory syndrome coronavirus (MERS-CoV) is a betacoronavirus which can cause acute respiratory distress in humans and is associated with a relatively high mortality rate. Since it was first identified in a patient who died in a Jeddah hospital in 2012, the World Health Organization has been notified of 1735 laboratory-confirmed cases from 27 countries, including 628 deaths. Most cases have occurred in Saudi Arabia. MERS-CoV ancestors may be found in Old World bats of the Vespertilionidae family. After a proposed bat to camel switching event, transmission of MERS-CoV to humans is likely to have been the result of multiple zoonotic transfers from dromedary camels. Human-to-human transmission appears to require close contact with infected persons, with outbreaks mainly occurring in hospital environments. Outbreaks have been associated with inadequate infection prevention and control implementation, resulting in recommendations on basic and more advanced infection prevention and control measures by the World Health Organization, and issuing of government guidelines based on these recommendations in affected countries including Saudi Arabia. Evolutionary changes in the virus, particularly in the viral spike protein which mediates virus-host cell contact may potentially increase transmission of this virus. Efforts are on-going to identify specific evidence-based therapies or vaccines. The broad-spectrum antiviral nitazoxanide has been shown to have in vitro activity against MERS-CoV. Synthetic peptides and candidate vaccines based on regions of the spike protein have shown promise in rodent and non-human primate models. GLS-5300, a prophylactic DNA-plasmid vaccine encoding S protein, is the first MERS-CoV vaccine to be tested in humans, while monoclonal antibody, m336 has given promising results in animal models and has potential for use in outbreak situations.

High-level expression of recombinant IgG1 by CHO K1 platform

Ningning Xu, Jianfa Ou, Al-Karim (Al) Gilani, Lufang Zhou, Margaret Liu

Frontiers of Chemical Science and Engineering 2015, Volume 9, Issue 3, Pages 376-380 doi: 10.1007/s11705-015-1531-5

Abstract: The Chinese Hamster Ovary (CHO K1) cell was used to express a targeted anti-cancer monoclonal antibody by optimizing the platform of the construction of production cell line in this study. The adherent CHO K1 was first adapted to suspension culture in chemical defined medium. Then the glutamine synthetase (GS) vector was applied to construct a single plasmid to overexpress a monoclonal antibody IgG1. Post transfection, the production of cell pool was optimized by glutamine-free selection and amplification using various concentrations of methionine sulfoximine. The best cell pool of CHO K1/IgG1 was used to screen the top single clone using the limiting dilution cloning. Finally, a high IgG1 production of 780 mg/L was obtained from a batch culture. This study demonstrated that the construction of high producing cell line, from gene to clone, could be completed within six month and the gene amplification improved protein production greatly.
