According to a report by the Tass news agency on July 17, Alexei Polisyuk, Director of the Second Department of CIS Affairs of the Russian Ministry of Foreign Affairs, told the Tass news agency that the United States has authorized Ukraine President Zelensky to launch a new strike on Russian territory.

Polisiuk pointed out: Washington is still fueling the escalation of the situation. They tried to justify their crimes while defending Kiev. Not only that, the Zelensky regime was also granted full powers to use American weapons to carry out new strikes on Russian territory.

He emphasized that the United States is still indulging in the dream of its own superior position, hoping that if Russia suffers strategic failure, it can safely hide across the ocean. He warned: Few among the American elite are aware of the risks of such arrogant and underestimating opponents ‘self-deception. For the United States and the world, the consequences may be unpredictable.

Polisiuk emphasized that behind the missile attack on Sevastopol, there was no doubt that U.S. military experts were providing various support services. They used the Pentagon’s drones circling over the area to target targets. (Russia) has made the most solemn representations to the U.S. ambassador to Moscow and the U.S. authorities in this regard, sending the clearest signal that terrorist attacks will lead to inevitable retaliation. As for the safety of the Crimean Peninsula and local residents, this is an absolute priority, and (Russia) is doing its best to provide reliable security. (Compiled by Tong Shiqun)

According to a report by Russian Satellite News Agency on July 16, US President Biden said on the 15th that Republican vice presidential candidate James Vance is a complete clone of Trump.

According to reports, Biden told reporters: He is a clone of Trump on all issues. I don’t see any difference.

Former U.S. President Trump received enough delegate votes at the Republican National Convention on the 15th and was officially nominated as the Republican presidential candidate in the 2024 U.S. presidential election. Trump also announced on the same day that he had chosen Ohio Senator Vance as his running mate.

Mike Johnson, Republican Speaker of the U.S. House of Representatives, officially announced at the convention that day that he would nominate Trump and Vance as Republican presidential and vice presidential candidates.

Vance was born in 1984. He was elected to the Ohio Senate in 2022 and was sworn in January 2023. He was a fierce critic of Trump, but has since become an ally of the former president.

According to a report by Yonhap News Agency on March 20, the South Korean government officially announced on the 20th the results of the allocation of 2000 places to expand the enrollment of 2000 students in the national medical school year. As a result, the medical school enrollment expansion plan has been settled in 27 years. In order to expand local medical infrastructure, the government will allocate 82% of the new places to non-capital area colleges and universities, and the remaining 18% will be allocated to Gyeonggi Province and Incheon areas. The number of schools in Seoul will remain unchanged.

Minister of Education Lee Zhouhao announced the results of the allocation of enrollment places for medical schools in the 2025 academic year, including the above contents, at the Central Government’s Seoul Office Building on the same day. The Ministry of Education received applications for medical school enrollment quotas from 40 universities across the country from February 22 to March 4. After that, it discussed with experts through the Expansion Allocation Committee and released the results.

The results show that the 27 university medical schools in non-capital areas will expand enrollment by 1639 students, accounting for 82% of the total enrollment expansion. At present, the number of students enrolled in non-capital medical schools is 2023, accounting for 662% of the national medical school enrollment scale (3058 students), and will increase to 3662 starting next year, accounting for 724% of the total enrollment scale.

In the Capital Region, the government has allocated 361 expanded enrollment places to five universities in Gyeonggi Province and Incheon City with enrollment sizes of less than 50 students, but the eight universities in Seoul have zero new places.

The Ministry of Education explained that the allocation of quotas is mainly considered to alleviate the imbalance between medical resources in the capital and non-capital areas, so that citizens can enjoy high-quality medical services in any region. The allocation committee comprehensively considered the materials submitted by each institution, educational conditions and future plans, and contribution to regions and essential medical care.

This is the government’s expansion of the enrollment scale of medical schools in 27 years. Analysts believe that although the medical profession still strongly resists the enrollment expansion policy through collective resignations, the government announced the allocation results on the same day, and the enrollment of medical students has been settled. The Ministry of Education plans to work with relevant departments to improve medical education conditions and provide support for institutions to hire professors and expand facilities.

Beijing, July 15 (Reporter Xie Xiyao) A spokesperson for the Ministry of Commerce said on the 15th that in order to safeguard the development rights and interests of China’s new energy vehicle industry, on March 26, China resorted to measures such as the U.S. Inflation Reduction Act on new energy vehicle subsidies. Respond to the WTO dispute settlement mechanism. As the United States failed to reach a solution through consultations with China, on July 15, China submitted a request to the WTO to establish an expert group.

The development of China’s new energy vehicle industry has made important contributions to global energy green transformation and climate change response. The spokesperson said that the U.S. Inflation Reduction Act takes the use of products from specific regions such as the United States as a prerequisite for subsidies, excludes products from WTO members such as China, artificially sets up trade barriers, and drives up the cost of green energy transformation. No matter how they are packaged and beautified, they cannot change the discriminatory, protectionist and violation of WTO rules of the subsidies involved. China resolutely promotes litigation procedures in order to safeguard the authority and effectiveness of the multilateral trading system with the WTO at its core and safeguard the joint international efforts to address climate change.

The spokesperson said that China agrees that WTO members implement industrial subsidies in a manner consistent with WTO rules, support green energy transformation, and promote economic and social development. China once again urges the United States to abide by WTO rules and stop abusing industrial policies to undermine international cooperation on climate change.

　　Used to open the computer, the trouble to listen to the shaoxing opera. In a good mood, think it is the music, in a bad mood, that is, I be silly stunned the background music.

　　

　　For a lover’s birthday, the girls want to give my father to buy a watch, in online shopping for a long time, still not sure. Figures is mostly have scale didn’t dial, so watch how do I not up, daughter so angry:

　　

　　”Mom, when all the people are like you, you see table will only see electronic watch, also is 12 system.”

　　

　　”Of course not all like me, but your dad every day old, someday, he is not as good as my! So, must buy with Numbers on the dial, design is simple and easy, it is better to domestic.”

　　

　　”Domestic mechanical or quartz? What brand do you want?”

　　

　　”To quartz, need not everyday winding, brand to the seagull.”

　　

　　”Gull? Never heard of.”

　　

　　”The Internet, as a Chinese, incredibly don’t know the seagull watch?”

　　

　　A daughter called me again:

　　

　　”Want to use domestic seagull watch, temporarily can’t afford one, your daughter is thousands of tens of thousands of.”

　　

　　Then, my daughter on QQ, send me a link, I open on see, isn’t it? Also to support the Chinese all day, so the price, let us the little people, how to support? A newlywed, bought a watch the seagulls, less than 200 dollars.

　　

　　Love came back from work, said to him. See I wasn’t impressed, he looked at me and said:

　　

　　”You are less than 200 pieces, I was monthly salary less than 120 yuan! For more than a month of wages, or to the present, not thousands of useful!”

　　

　　”Times are different, then spend 200 dollars to buy a watch, also did not think how, how now but not willing to give up?”

　　

　　”Don’t think that way, that was didn’t spend your money.”

　　

　　”You don’t say you bought me a watch, to now you still love dearly!”

　　

　　Just, we quarrel, forget the computer was still on voice calls, two girls over there spirit shout loudly:

　　

　　”How noisy again? Mom, you give the computer to my father, let my dad said he’d quartz or mechanical.” , I put my computer to lover.

　　

　　”I want to mechanical, don’t be too high price, didn’t I give you remit money.”

　　

　　”Dial? Digital or graduated? Color should be black and white or grey days?”

　　

　　”Digital calibration, color should be black and white.”

　　

　　”Oh, is it not a watch? Things are!” I can’t help by chimed in.

　　

　　”Dad, are you sure?”

　　

　　”Sure, your mother rush to surf the Internet!”

　　

　　”Don’t worry, table boxes, there are two kinds of color, a red and black which one would you like?”

　　

　　”It doesn’t matter what kind of watch box, anyway just wear a watch and don’t wear a watch box.” And I say a word of mouth.

　　

　　”Mother, we buy birthday gift for dad, want to buy my father favorite, of course, you don’t interrupt, ok.”

　　

　　”What color do you like table box, what colour will! Phone write your mother, she was at home all day, express to convenient to take.”

　　

　　Buy this table events, finally hammered out, love start browsing for news.

　　

　　”Take headphones to you, I want to quiet for a while.”

　　

　　”Want to quiet, what did you do for dinner?” Yeah, just and daughter discuss watch things, how to forget to do dinner?

　　

　　You see, this want to quiet for a moment, really difficult! You can close the earth is the ear, you don’t shut the appetite of the world! Darling still cooking go to! Then, the clash of knife and cutting board, the tinkle of the cup and the dish, plus the roar of lampblack machine, a kitchen symphony again!

　　

　　”Shut the kitchen door, noisy dead.” Lover to roar, I closed the door of the kitchen. Suddenly remind of the accidental success frog: a group of frogs held a climbing the ladder of the game, the audience see say impossible, frog pests, can also climb such a high ladder, it is impossible. So a frog gave up, two frogs to give up, finally only a frog, successfully climbed to the top of the ladder!

　　

　　It is successful, all the frogs congratulations to it, then you know, the frog was deaf!

　　

　　Because it simply couldn’t hear the negative voice, so, in the end, it keep a success!

　　

　　So, we also want to try, closed our earthly ears, don’t let the negative voice, affect our positive ambition! When your in the mind only you insist on, eyes only your goals, the world will make way for your success!

　　Most protein is like a jumble of atoms packed together. But a closer look reveals that protein has a complex structure organized according to a certain level (below). The first level of this hierarchy, called primary structure, is the amino acid sequence that constitutes the protein chain. Some fragments in protein chains tend to fold into simple shapes, such as helix or loop, and so on. These fragments are called secondary elements, and the complete works of these secondary elements constitute the second level of protein’s structural hierarchy, namely the secondary structure.More importantly, put Antibody Phage Display Service It is imperative for us to make thorough analysis and maximize its social function. https://www.alphalifetech.com/

　　

　　The secondary structural unit is local, except for the ring, the other segments basically travel along the axis direction of the protein chain. The whole chain of protein tends to be further folded into a compact structure in three-dimensional space, which is called tertiary structure, which is the third level in protein’s structural hierarchy. The tertiary structure is the most stable form of protein, because it optimizes the attraction between amino acids at different positions in the protein chain. Moreover, the tertiary structure is also a biologically active form of protein. If this form is destroyed, protein will lose some or all of its functions. Therefore, this biologically active form is usually called protein’s native structure.

　　

　　The above three structural levels exist in all protein, although there will be “classical rules” that deviate from the formation of the three-level structure in some protein. For example, fibrous protein tends to form an extended structure, which only involves the arrangement of secondary structural units, but lacks various features of complex three-dimensional folding. Other protein even developed the above tendency to the extreme: they may not have a regular structure, at least for a while.

　　Memorize 20 kinds of amino acids and try to remember English abbreviations and codes as much as possible, because exams often appear directly with codes. Protein’s molecular structure often examines the manifestations of various levels of structure and their bonds. The physical and chemical properties of protein and the purification of protein usually use the physical and chemical properties of protein to purify protein without destroying the structure of protein. Pay attention to the identification of amino acids and physical and chemical properties of protein. The basic unit of nucleic acid is nucleotide, which is composed of multiple nucleotides, and the connecting bond between nucleotides is 3′, 5′- phosphodiester bond. DNA double helix structure, in which two bases exist in strict accordance with A = T (two hydrogen bonds) and G triple C (three hydrogen bonds), and the characteristics of various RNA.

　　

　　In addition, we should pay attention to some commonly used concepts in nucleic acid problem solving. The first thing that enzymes should pay attention to is some basic concepts, such as ribozyme, deoxyribozyme, enzyme activity center, isozyme, isomerase and so on. The key point of the Metric Equation test is V=Vmax[S” target=_blank>/Km+[S” target=_blank>, which explains the equation of the relationship between the concentration of enzymatic reaction and the reaction speed.

　　According to the characteristics of allosteric enzymes, it should be noted that allosteric regulation can cause conformational changes of enzymes. It is important to pay special attention here that configuration refers to the basic structural composition of substances, and conformation refers to the spatial change of substances. Allosteric regulation can cause the conformational change of enzymes, but not the conformational change of enzymes.

　　Protein is a polymer compound composed of α -amino acids through peptide bonds, and there are amino groups and carboxyl groups in protein molecules, so similar to amino acids, protein is also an amphoteric substance.Mentioned in the article recombinant proteins Born with strong vitality, you can turn a cocoon into a butterfly and become the best yourself after wind and rain. https://www.alphalifetech.com/

　　

　　(1) Hydrolysis reaction

　　

　　Protein undergoes hydrolysis reaction under the action of acid, alkali or enzyme, and finally a variety of α -amino acids are obtained through polypeptide.

　　

　　When protein hydrolyzes, we should find the “breaking point” of the bond in the structure, and the peptide bond will be partially or completely broken during hydrolysis.

　　

　　(2) Colloidal properties

　　

　　Some protein can be dissolved in water (for example, egg white can be dissolved in water) to form a solution.

　　

　　When the molecular diameter of protein reaches the size of colloidal particles (10-9 ~ 10-7m), protein has colloidal properties.

　　

　　(3) precipitation

　　

　　Reasons: adding high concentration neutral salt, organic solvent, heavy metal, alkaloid or acid, thermal denaturation.

　　

　　A small amount of salt (such as ammonium sulfate, sodium sulfate, etc.) can promote the dissolution of protein. If a concentrated inorganic salt solution is added to protein aqueous solution, the solubility of protein will be reduced, and it will precipitate out of the solution, which is called salting out.

　　

　　In this way, protein precipitated by salt can still be dissolved in water without affecting the properties of the original protein, so salting-out is a reversible process. Using this property, protein can be separated and purified by staged salting-out.

　　

　　(4) degeneration

　　

　　Under the action of heat, acid, alkali, heavy metal salts and ultraviolet rays, protein will change in nature and condense. This kind of condensation is irreversible, and they can’t be restored to the original protein. This change in protein is called transsexuality. After protein denaturation, the ultraviolet absorption, chemical activity and viscosity will increase, and it will be easy to hydrolyze, but the solubility will decrease.

　　

　　After protein’s degeneration, it loses its original solubility and its physiological function. Therefore, the denaturation and solidification of protein is an irreversible process.
