The purpose of summer health in addition to consolidate the basis of human health, but also more important is to help us summer in health, but some foods make the summer health plan to fall short. During summer health, some foods are definitely not eaten, such as:
1. Flowers
In the summer, all the flowers are freaking out, and Chinese medicine often takes some treatments and develops wines and teas after some processing. However, it does not mean that all the flowers can be used for wine making and tea making. The nature of flowers varies according to the type of flower. If you don't know how to make tea, you can easily cause poisoning.
For example, the flowers of oleander can not be used freely to soak in wine and food. There are many kinds of glycosaminolin toxins in this flower. In araceae flowers and leaves, oxalic acid and asparatoxin are also contained, and they will appear in different degrees after consumption. Poisoning reaction.
2. Leek:
The leek was originally an essential spice for every meal of the Northerners, and now the South has gradually risen with the enthusiasm of eating leek. The leek, with its delicious and highly effective nutrition, has been accepted by the people of our country. However, in recent sampling inspections by the National Food Safety Department, it has been found that organic phosphorus pesticide residues in leek are generally high. Such substances can cause neurological disorders after entering the body. Patients with poisoning often experience symptoms such as hyperhidrosis and language disorders. .
Note: Before eating leek, it is better to soak leeks in brackish water for more than half a day, so that some residual pesticides in leeks can be eliminated.
PCR ( Polymerase Chain Reaction)
It provides a way to make more copies of a portion of DNA.
We need to have PCR ingredients that include DNA portion, Buffer solution, Primer+DNA (tap polymerase), and Nucleotides during the preparation step.
In the step of PCR sequence, there are three steps in this section.
Step 1 Denaturation
The addition of heat is needed to separate the two strands of the DNA molecule.
Step 2 Annealing
Temperature, is going to be cool in this step, should allow the primers to bind to the specific segments.
Step 3 DNA Synthesis
To make more copies of the DNA.
Those three steps above keep repeating to make enough copies of the DNA fragments. It is the principle of how PCR machine works.
