Original title: The rice gene can not be transferred to a kind of safe nutrition
Beijing Evening News (Reporter Zhang Hang) Recently, 61 academicians requested the industrialization of genetically modified rice. The issue of the safety of genetically modified foods has once again attracted worldwide attention. The reporter learned from China Agricultural University yesterday that the 90-day feeding trial of genetically modified rice miniature pigs undertaken by experts from the university has been completed. From the results, GM rice has the same nutrition and safety as non-GM rice.
It is understood that at present, China's crops that have been approved for the production of genetically modified and applied safety certificates and are within the valid period include cotton, rice, corn and papaya. However, it cannot be commercialized immediately. According to the "Seed Law of the People's Republic of China," genetically modified crops still need to obtain certification certificates, production licenses, and operating licenses before they can enter commercial cultivation. At present, only cotton and papaya are approved for commercial planting in China, and genetically modified rice and genetically modified corn have not been approved by the Seed Law.
Lin Yongjun, a professor at Huazhong Agricultural University and the leader of the National Major Science and Technology Project “Planting New Variety of Insect-resistant Transgenic Rice†recently disclosed that the Ministry of Agriculture is currently commissioning a 90-day feeding trial of miniature pigs of genetically modified rice at the China Agricultural University and commissioned the Chinese Academy of Medical Sciences to do the research. Rhesus monkey feeding test.
Yesterday, Prof. Huang Kunlun of the College of Food Science and Nutritional Engineering of China Agricultural University responded to the reporter’s report that the pig feeding test for the BT gene-resistant rice had been completed. The results showed that the BT transgenic rice and non-transgenic rice were Pigs have the same nutrition and safety. Huang Kunlun said that because the physiology and anatomy of pigs are very similar to humans, they are widely used in scientific research in biomedicine and other fields. Therefore, using pigs as a test can reflect the safety of GM rice for human consumption.
Huang Kunlun introduced that during the 90-day feeding period, pigs fed non-genetically modified rice feed and genetically modified rice feed had almost the same growth indicators of body weight, body length, chest circumference, and body height; blood biochemical and blood routine indicators of pigs were all indicators of health. Within the scope of the study, there were no significant weight differences in organs such as heart, liver, kidney, and spleen, and the reproductive system developed normally; no transgenic rice was found to cause pathological changes in the experimental animals. Therefore, it can be said that the transgenic BT rice and non-transgenic rice have the same nutrition and safety for pigs. This conclusion is consistent with the conclusion of the 90-day feeding trial in experimental rats.
As for why such safety tests should be conducted, Huang Kunlun said that since the large-scale commercialization of genetically modified crops in 1996, the planting area has increased at an annual rate of about 10%, and in 2012, the area of ​​genetically modified crops grown globally reached 170 million hectares. However, safety concerns and controversies about genetically modified foods have continued. Therefore, safety assessment is a prerequisite for the introduction of genetically modified foods into the market, and it is also the basis for the government to administer genetically modified products. Genetically modified foods must undergo nutrition before they are approved for commercial production. Toxicology, sensitization and other aspects of safety assessment.
Mini piston pump is small-sized pump that use a reciprocating motion to transfer fluids. They are commonly used in various applications, such as medical devices, laboratory equipment, and industrial automation. Mini piston pumps can be classified into different categories based on various factors, such as their working principle, fluid type, and application.
Based on working principle, mini piston pumps can be classified into two types: positive displacement pumps and dynamic pumps. Positive displacement pumps work by trapping a fixed amount of fluid and then forcing it through the pump chamber, whereas dynamic pumps use rotating impellers to generate fluid flow. Mini piston pumps are typically positive displacement pumps, which means they are designed to move a fixed amount of fluid with each stroke of the piston.
Based on the type of fluid they handle, mini piston pumps can be classified into two categories: mini water pumps and air pump. Liquid pumps are used to transfer liquids, such as water, oil, and chemicals, whereas gas pumps are used to transfer gases, such as air and other compressed gases.
Based on their application, mini piston pumps can be classified into various categories, such as medical pumps, laboratory pumps, and industrial pumps. Medical pumps are used in medical devices, such as insulin pumps, drug delivery pumps, and infusion pumps. Laboratory pumps are used in laboratory equipment, such as chromatography systems and spectrophotometers. Industrial pumps are used in various industrial applications, such as chemical processing, food processing, and water treatment.
In summary, mini piston pumps are versatile pumps that can be classified into different categories based on their working principle, fluid type, and application. Understanding these classifications can help users choose the right pump for their specific needs.
