What are the ways to try and design a cell biology experiment?
Here are some cell biology experiments: * * 1. Cell culture-related experiments ** 1. * * Primary Cultivation Method ** - * * Tissue-block culture method **: Directly remove cells, tissues, or organs from the body and place the tissue block in a suitable culture environment. This method is relatively simple to operate, and the cells are easier to grow. For example, when cultivating cardiac muscle tissue, the beating of the tissue block can sometimes be observed. - * * Digestive culture method **: The tissue is broken down into individual cells by digestive zymes and then cultured. 2. * * Subculture **: When the cells grow to the confluence of a single layer in the primary culture, subculture is required due to space and nutrition constraints. The cells were separated from the original culture vessel and then seeded into a new culture vessel to continue the culture, so as to reproduce more cells and prevent the cells from deteriorating and dying. * * 2. Cell Function Testing Experiment ** 1. * * Cell Growth Detection ** - * * Cell Metabolic Activity Detection (Based on MTT-test, CCK-8, etc.)**: For example, the MTT-test (thiazole-blue) method can measure the activity of the mitochondria by adding a thiazolium-based salt to the cells, thereby reflecting the cell proliferations. 2. * * Cell cycle detection **: Use a specific staining method or technique to determine which stage of the cell cycle the cells are in (such as G1, S, G2, and M). For example, flow biochemistry can be used in combination with the corresponding cell cycle detection reagents to analyze the cell cycle distribution. 3. * * Cell death detection **: - * * morphological observation method **: Observing the changes in the shape of cells through an optical microscope or an electron microscope. Apoptotic cells will show features such as cell contraction, nuclear condensation, condensation of Chromatin, and the formation of an necrotic body. - * * Biochemical detection method **: For example, detecting the activity of Caspase in cells. Caspase is activated during the process of cell death, and its activity can be determined by using specific substances and detection reagents. It can also determine the cell death by detecting the extroversion of PhosphatidylSerine (PS) in the cell membrane. For example, Annexin V-FITL/Pi double staining method can be used. Annexin V can specifically bind to the extroversion of PS, and then combine with Propidium Iodide (Pi) to distinguish early and late cells in the process of cell death. 4. * * Cell invasion and migration experiment ** - * * Cell Scratch Experiment **: Create a "scratch" on a single layer of cultured cells, and then observe the ability of the cells to migrate to the scratch area to evaluate the migration characteristics of the cells. - * * Transwell experiment (cell invasion experiment)**: A special chamber (Transwell chamber) is used. There is a membrane in the middle of the chamber. The membrane can be coated with an extra-cellular matrix component (such as Matrigel) to simulate the extra-cellular matrix barrier in the body. The cells were seeded in the upper chamber, and a medium containing a Chemokine was added to the lower chamber to observe the ability of the cells to pass through the membrane. If the membrane was coated with an extra cellular matrix component, the invasive ability of the cells could be tested. If the membrane was not coated, the migration ability of the cells could be tested. * * 3. Cell structure research experiment ** 1. * * Genetic Analysis Technique **: - When the cell was in the middle of division, the highest degree of condensation of the nuclei was the best time to observe and analyze the shape of the nuclei. Through the analysis of the shape and number of microorganisms, it could be used for clinical diagnosis, research on the genetic basis of infertility and habitual abortion, prevention of the birth of children with abnormal microorganisms, and gene positioning. 2. * * electron microscope technology **: includes scanning electron microscope and transmission electron microscope. It can be used to observe the ultra-structure of cells, such as the shape of the cell surface and the structure of the organelle. * * 4. Special Cell Cultivation Experiment ** 1. * * organ culture **: Special devices are used to allow organs, organ primordium, or parts of them to survive outside the body and maintain their original structure and functions. For example, the organ culture method, the stainless steel metal grid method, the Wolff culture method, and the spread box culture method could be used to observe the interaction between tissues, the differentiation of tissues and cells, and the effects of external factors (including drugs) on tissues and cells. * * 5. Radiation-related experiments ** 1. Autoradiography: A method that uses the photosensitizing effect of the radioactive ionising radiation on the nuclear colloid to display the distribution, quantity, and location of the radiation in the specimen or sample. It could be combined with electron microscopes and biological molecules to study the distribution and metabolism of radioactive substances in tissues and cells. It could also reveal changes in the synthesis of nuclei and damage. Read more exciting novels for free
History of Microbiological Biochemical Testing
Based on context alone Microbiological biochemical testing had a long history of development. In the early days, the study of microorganisms was mainly focused on morphological observation. As the study of the physiological functions of microorganisms deepened, people began to explore the biochemical characteristics of microorganisms. At the end of the 19th century, microbiologists gradually realized that microorganisms would produce specific biochemical reactions during metabolism, which became the beginning of biochemical testing of microorganisms. In the 20th century, with the development of chemical analysis technology and equipment, the biochemical test technology of microorganisms had made great progress. For example, by detecting biochemical indicators such as the ability of microorganisms to ferment sugar and decompose protein, they could more accurately identify different types of microorganisms. Various biochemical test methods were emerging, such as sugar fermentation test, indoles test, hydrogen sulfureted test, etc. These traditional biochemical tests had become an important means of identification of microorganisms. With the development of molecular biology technology, the biochemical test of microorganisms was further expanded and deepened on the original basis. On the one hand, new biochemical indicators were constantly discovered, which improved the accuracy and resolution of the identification of microorganisms. On the other hand, automated biochemical analysis instruments for microorganisms began to appear, which greatly improved the detection efficiency, making the biochemical test of microorganisms play an irreplaceable role in many fields such as medicine, food, and the environment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There is a large piece of inflammation in the lungs, what medicine does the effect take good?
If there is inflammation in the lungs, antibiotics can be used for treatment, such as Cephalothorins (Cefdinir Dispersible Tablets, Cefixime, etc.), Fluoroindoles (Levofroxaxin, Moxiaxin, etc.), and Cyclolides (Roximethrin, Azimethrin, Clarisons, etc.). If it is accompanied by symptoms such as fever, cough, and expectoration, antipyretic, cough, and expectorant drugs should be added, such as buffalo, paracem, lung cough mixture, compound licorice tablets, etc. However, for some older patients who had been bedridden for a long time, or patients with underlying diseases, or patients who were uncertain of their own conditions, it was not recommended to use their own medication. They must have a doctor's guidance. If necessary, they should be given phlegm culture and drug sensitivity test. According to the drug sensitivity test results, appropriate antibiotics should be selected for treatment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
