      Hi everyone, today I'd like to talk about Nucleic Acid Medicine, like the mRNA vaccine. Scientists make efforts to enable nucleic acid medicine to work properly in the body. I'll tell you the method.      Nucleic acids are made of sugars, bases, and phosphates. DNA and RNA are also nucleic acids. They work on gene expressions, restoring, and adjustments. We use those features to treat and prevent diseases.     Ordinary RNA is degraded by enzymes in the body, so a cap structure is added to prevent degradation. In our body, some enzymes work to break bacterial DNA or RNA. To recognize bacterial nucleic acids and theirs, their nucleic acids have a cap structure. If a nucleic acid doesn't have the cap, it'll be recognized and degraded by enzymes.      Lipid molecules and carrier molecules are used to make a parcel that carries the nucleic acid, to prevent it from being attacked by immune cells and enable it to go accurately to the...

     Hi everyone, today I'd like to talk about my hobby. One of my hobbies is watching movies on the Internet. When I was an elementary school student, my friend told me about a fan movie site, which was NicoNico Video.       At the site, a lot of people did their best to do something waste without getting money. Their engine was curiosity and thought that they hope to do something fun. I had watched those videos for a long time. However, I stopped watching them when I became a high school student because a lot of creators quit video making, and most users were changed through the years. Videos newly uploaded and comments for them became not interesting.      For the years, the site made me fun and excited. I'm sure that the site affected my life largely. I can't forget the excitement, so I watch videos on YouTube. However, I have never felt such excitement like that. I hope the Internet to be unpopular and free like before.

      Today I listened to a podcast about British food. In that, a man saw bland and weird food. Especially, they talked about the chip butty, French fries in the sandwich. They said it was carbs on carbs. The chip butty was so bland that he ate with HP Sauce, British spicy sauce. It seemed to go well with the butty. He got into their travel in British.

 Hi everyone, today I'd like to talk about mitochondria. The organelle is well known for making energy from glucose in cells, but it plays other important roles. I'll tell you unfamiliar functions.  Mitochondria have many kinds of enzymes. Those make stuff for steroid hormones such as estrogen and testosterone. The hormones are important, not only on secondary sex characters but also on our lives. The enzymes in mitochondria also create the iron-sulfur cluster, the molecular is necessary for the reductive reactions.  Mitochondria include a heme-protein, cytochrome, one of the proteins to make energy. When cytochrome is out of mitochondria, it induces apoptosis. To control the cell's death, a lot of molecular work together especially on the mitochondria membrane.
