Question: Background: Porcine epidemic diarrhea virus (PEDV) is emerging as a pathogenic coronavirus that causes a huge economic burden to the swine industry. Interaction of the viral spike (S) surface glycoprotein with the host cell receptor is recognized as the first step of infection and is the main determinant of virus tropism. The mechanisms by which neutralizing antibodies inhibit PEDV have not been defined. Isolating PEDV neutralizing antibodies are crucial to identifying the receptor-binding domains of the viral spike and elucidating the mechanism of protection against PEDV infection. Methods: B cell hybridoma technique was used to generate hybridoma cells that secrete specific antibodies. E.coli prokaryotic expression system and Bac-to-Bac expression system were used to identify the target protein of each monoclonal antibody. qPCR was performed to analyze PEDV binding to Vero E6 cells with neutralizing antibody. Results: We identified 10 monoclonal antibodies using hybridoma technology. Remarkably, 4 mAbs (designed 2G8, 2B11, 3D9, 1E3) neutralized virus infection potently, of which 2B11 and 1E3 targeted the conformational epitope of the PEDV S protein. qPCR results showed that both 2B11 and 2G8 blocked virus entry into Vero cells. Conclusion: The data suggested that PEDV neutralizing antibody inhibited virus infection by binding to infectious virions, which could work as a tool to find the receptor-binding domains.

Answer: Neutralizing antibodies against porcine epidemic diarrhea virus block virus attachment and internalization


Question: Food security in the Middle East is directly affected by a challenging combination of ongoing destructive conflicts, a global economic downturn, widespread poverty, high population growth, corruption, intolerance, and the potentially damaging consequences of climate change. Many Arab countries demonstrate nearly all the features of those countries classified as poor, less developed, or failing to achieve the eight Millennium Goals. Even the economies of the richer oil-exporting countries in the Region have been seriously damaged by the downturn in oil and gas prices as new sources come on stream elsewhere and demand falls as a result of renewable sources of energy becoming available. Climate change predictions for the Region are worrisome even if most of the environmental commitments made by countries at the UN Climate Change Conference in Paris at the end of 2015 are delivered. Large parts of the Region already suffer from periods of extreme temperatures and shortages of fresh water, so harsher conditions of higher temperatures and weather extremes pose special problems for inhabitants and policymakers, with heightened geopolitical risks and uncertainties. Agriculture is especially vulnerable. Modern agricultural technologies with improved cultivars and livestock breeds must displace poor agricultural and pastoral practices. Larger-scale, bettercapitalised production units are required with policy shifts to remove marketdistorting subsidies, tariffs, and other regulatory impedances. Agricultural "roadmaps" are needed to encourage the most appropriate crops and maintain livestock in the most appropriate places. The trading of meat, dairy products and many types of crops to water-poor regions can be regarded as an efficient way to 261 redistribute water. In unsettled times, food security requires protection of foodproducing, food-processing, and food-distribution industries are protected along with research and development facilities, and the maintenance of skilled personnel. There are doubts as to whether agencies of the United Nations, other international agencies, donor countries and charities are able to provide adequate humanitarian aid and humanitarian intervention to enable safeguarding of displaced peoples and ensuring the resumption of normal peaceful conditions essential for food security to be guaranteed. Promises of aid funds must become reality, followed by the establishment of functional supply and transport networks, and rapid transition to self-reliance thereafter. Food security and social stability are inextricably linked. The solution to the food-security problems in the Region ultimately lies in the actions of governments, businesses and individuals. Governments need embedded scientific and technological expertise, strong civil-society institutions, integrity, and a particular focus on high-quality education.

Answer: Food Security in an Insecure Future


Question: A 70-year-old woman was admitted to our hospital for dyspnea and a fever of 2 weeks duration. Chest imaging showed bilateral infiltration, and a rapid diagnostic test for influenza virus, Mycoplasma pneumoniae, Streptococcus pneumoniae, and Legionella spp. was negative. She was intubated and mechanically ventilated and underwent bronchoalveolar lavage. Bronchoalveolar lavage fluid yielded no significant pathogens, and the multiplex polymerase chain reaction test was positive only for human bocavirus. Specific antibodies against significant pathogens were not increased in paired sera, so we diagnosed her with primary human bocavirus pneumonia.

Answer:
Fatal Primary Human Bocavirus Pneumonia in an Immunocompetent Adult
