According to British media news, scientists have recently cultivated 300 cows that have been injected with human genes so that their milk contains the same nutrient content and fat content as breast milk. This latest advance in genetic modification makes infants drink in the near future. The “human†milk produced by cows became possible. Scientists also said that this product makes mothers face a new alternative to traditional infant formula formula.
However, this move has also been condemned by social activists who say that the safety of milk cannot be guaranteed. The important difference between human milk and milk is manifested in several aspects. First, human milk contains a lot of nutrients that are beneficial to infant growth and the immune system. Milk, on the other hand, contains less fat and carbohydrates, and does not contain antibodies against diseases. Not conducive to infant digestion. Professor Li Ning, who carried out this research at China Agricultural University, said that the milk they produce will be as safe as milk from ordinary dairy cows.
"The taste of this kind of milk is stronger than that of ordinary milk. In 10 years people will be able to buy this milk product that resembles human milk in the supermarket." However, Patty Rundle of the Baby Food Action said: "We need to make regulations to guarantee the human body. Health, such products may have huge risks that we cannot predict. Milk cannot be like breastmilk, nor can it be a breast milk-like product. Breast milk has the uniqueness of being free from risk.†Professor Lee’s research team published the study. In the journal "Public Science Library Comprehensive," they talked about the use of cloning technology to inject human genes into the DNA of Holstein cows.
The milk produced by one breed of genetically modified cow contains lysozyme, an antibacterial protein found in human milk that protects infants from infection. In addition, genetically modified cows also produce human lactoferrin, which enhances the proteins of the immune system. The third human milk protein found in this type of milk is called alpha-lactalbumin. Professor Li also claimed that his research had increased one-fifth of the milk fat content and changed the solids level, making it closer to the human milk component.
However, social protectionists believe that the production of GM cows is not conducive to animal welfare. The two experiments conducted by the Chinese people produced a total of 42 GM cows. Only 26 of them survived. Ten of them died after they were born and the remaining six died within six months after birth. A spokesman for the Royal Society of Animal Protection of the United Kingdom said: "Cloning animals are often faced with health and welfare issues. This may be the biggest concern. Why do we need this kind of milk, which can provide us with what we cannot currently receive?"
Helen Wallace, an inspector of the British Gene Surveillance Agency, said: “The type of milk produced by such cows is safe for humans. This is still the biggest problem faced. To get answers, large clinical trials must be conducted.†China's Genetically Modified Food The norms are much broader than Europe. This type of genetically modified milk that needs to be sold in the UK must be approved by the EU and passed stringent safety tests.
However, some British scientists believe that this study is of great value. Prof. Keith Campbell, a biologist at the University of Nottingham, believes that genetically modified animals are not harmful to health unless scientists deliberately add a gene that makes milk toxic. He was a synthetic clone in 1996. One of the members of Yangduo Research. "Successful GM foods can provide better products, which can bring huge benefits to consumers." This GM milk can increase the sales of Asian milk products, where at least nine out of ten people suffer from lactose deficiency. Tolerance, eating milk is often accompanied by stomach discomfort and cramps.
Magnetic push pins can be used on any ferromagnetic surface.Someone could easily use magnetic push pins on a bulletin board, magnetic white board, magnetic chock board, fridge, food truck, big industrial equipment... Magnetic push pins can be used at office,meeting room, classroom,studio, corridor,workshop... People are like to use magnetic push pins because magnetic push pins are no harm to the surface which been contacted. After the use, someone could remove or reuse the magnet easily. We produce different color of magnetic push pins in three sizes. The Magnetic Push Pin is formed by Neodymium Magnet N35 and ABS color plastic.one pieces of magnetic push pin could hold 5~7 A4 paper thus it is very convenient. The chess design plastic is good to hold and someone`s hand contact to the magnet could be avoided. .The magnetism of magnet could exist for more than many years of use, also please keep magnetic push pin away from the electric products and cards.
