The new crown virus has broken the otherwise peaceful life and messed up people's lives. It is because of the extremely high risk of infection that everyone is afraid and cautious. When difficulties arise, methods to solve them will follow. In order to determine whether they are infected with the new crown virus, nucleic acid testing has made its debut. Nucleic acid testing is an important means to confirm the new coronavirus, and it is also one of the important processes for patients to confirm the diagnosis. To do nucleic acid testing, Nucleic acid detection has the characteristics of early diagnosis, high sensitivity and specificity, and is the "gold standard" for diagnosing new coronary pneumonia. Currently, the most widely used real-time fluorescent quantitative RT-PCR technology. Generally, the two targets located on the ORF1ab and N genes of the virus are detected. The same specimen must meet the double target positive or the repeated test as single target positive, or the two specimens must meet the single target at the same time to confirm the positive of SARS-CoV-2 virus nucleic acid. The virus transport medium developed by Desheng for the new coronavirus is inactivated and non-inactivated. The nucleic acid detection mainly uses an inactivated virus transport medium, which can instantly crack the pathogen and release the nucleic acid, and the protective agent can prevent the nucleic acid from being degraded. . By fully mixing the collected sample with the virus lysis solution and the virus nucleic acid preservation solution, the virus in the sample can be inactivated. Colleagues can effectively ensure the integrity of the virus nucleic acid in the sample. The collected sample can be transported and processed under normal temperature conditions. Long-term preservation. The saved viral RNA samples can be widely used in genetic testing, enzyme-linked immunoassay (ELISA), PCR testing, etc. Although Desheng does not currently have the technology to produce nucleic acid detection kits, it can produce virus preservation solutions, disposable virus sampling tubes and biological buffers required for nucleic acid detection, as well as luminol and acridine as the raw materials for antigen and antibody detection. ester. Desheng is willing to contribute its part in the fight against the epidemic, and is willing to fight for the cause of human health.
Oregano - scientifically named Origanum vulgare by Carolus Linnaeus – is a common species of Origanum, a genus of the mint family (Lamiaceae). It is native to warm-temperate western and south western Eurasia and the Mediterranean region. Oregano is a perennial herb, growing from 20–80 cm tall, with opposite leaves 1- 4 cm long. The flowers are purple, 3–4 mm long, produced in erect spikes. It is sometimes called Wild Marjoram, and its close relative O. majoramum is then known as "Sweet Marjoram". Uses Culinary Dried oregano for culinary use. Oregano growing in a field. Oregano is an important culinary herb. It is particularly widely used in Turkish, Greek, Portuguese, Spanish, Latin American, and Italian cuisine. It is the leaves that are used in cooking, and the dried herb is often more flavourful than the fresh. [2] Oregano [3] is often used in tomato sauces, fried vegetables, and grilled meat. Together with basil, it contributes much to the distinctive character of many Italian dishes. It is commonly used by local chefs in southern Philippines when boiling carabao or cow meat to eliminate the odor of the meat, and to add a nice, spicy flavor. Oregano combines nicely with pickled olives, capers, and lovage leaves. Unlike most Italian herbs, [citation needed] oregano works with hot and spicy food, which is popular in southern Italy. Oregano is an indispensable ingredient in Greek cuisine. Oregano adds flavor to Greek salad and is usually added to the lemon-olive oil sauce that accompanies many fish or meat barbecues and some casseroles. In Turkish Cuisine, oregano is mostly used for flavoring meat, especially for mutton and lamb. In barbecue and kebab restaurants, it can be usually found on table, together with paprika, salt and pepper. Oregano growing in a pot. It has an aromatic, warm and slightly bitter taste. It varies in intensity; good quality oregano is so strong that it almost numbs the tongue, but the cultivars adapted to colder climates have often unsatisfactory flavor. The influence of climate, season and soil on the composition of the essential oil is greater than the difference between the various species. The related species Origanum onites (Greece, Turkey) and O. heracleoticum (Italy, Balkan Peninsula, West Asia) have similar flavors. A closely related plant is marjoram from Turkey, which, however, differs significantly in taste, because phenolic compounds are missing in its essential oil. Some breeds show a flavor intermediate between oregano and marjoram.

With the recurrence of asymptomatic, nucleic acid testing cannot be stopped for a moment. This is not only a protection for everyone, but also a protection for yourself. Speaking of nucleic acid testing, we have to bring up our virus sampling tube again. Its choice also plays a key role. Why use a virus sampling tube? Virus detection is different from conventional biochemical detection. The virus itself is a simple microorganism that must be parasitic in living cells. After sampling, the virus leaves the host cell, and its protein shell and nucleic acid will be quickly degraded in the sampling tube, so the nucleic acid During the test, it is impossible to determine whether the initially collected sample contains the virus, and it is easy to cause false negatives. What are the requirements for an excellent virus sampling tube? 1. In terms of sample effectiveness: The non-inactivated virus preservation solution must maintain the activity of the pathogen's infectious agent. Preferably, it can preserve the activity of the virus at room temperature. The inactivated virus preservation solution needs to inactivate the virus but maintain the nucleic acid of the virus to meet the time from sample sampling to laboratory testing. It is necessary to limit and prevent the reproduction of symbiotic microorganisms to ensure the reliability of diagnostic tests. 2. In terms of safety: Because the virus sampling tubes are basically all infectious substances, and some are highly pathogenic infectious substances, the requirements for packaging containers are very strict, and they need to meet safety and ensure that liquids do not leak during transportation. . So what is the virus preservation solution? Under what circumstances do I need to use a virus preservation solution? The virus preservation solution is a protective liquid medium added to the virus sampling tube to protect the sample after the nasopharyngeal swab is sampled. Normally, nucleic acid PCR cannot be directly performed at the sample collection site during nucleic acid detection. If the sample collected by the swab needs to be transferred and transported, it is necessary to add a virus preservation solution. Why is the virus preservation solution divided into inactivated and non-inactivated? After the virus samples are collected, there is usually no way to test in time at the sample sampling site, so the collected virus swab samples need to be transported, and the virus itself will be quickly lysed outside the body and affect subsequent testing, so when storing and transporting , You need to add a virus preservation solution. For different detection purposes, you need to use different virus preservation solutions and different virus detection experimental conditions, so it is divided into two types of preservation solutions, inactivated and non-inactivated. There are no other microorganisms, causing the virus to decompose after sampling or other influences causing false detections.
In Laos, (it known as pak i tou, lemon basil is used extensively in soups, stews, curries and stir-fried dishes as it is the most commonly used type of basil in Laos. Many Lao stews require the use of lemon basil as no other basil varieties are acceptable as substitutes. The most popular Lao stew called or lam uses lemon basil as a key ingredient. Lemon basil is the only basil used much in Indonesian cuisine, where it is called kemangi. It is often eaten raw with salad or lalap (raw vegetables) and accompanied by sambal. Lemon basil is often used to season certain Indonesian dishes, such as curries, soup, stew and steamed or grilled dishes. In Thailand, Lemon basil, called maenglak (Thai, is one of several types of basil used in Thai cuisine. The leaves are used in certain Thai curries and it is also indispensable for the noodle dish khanom chin nam ya. In the Philippines,where it is called sangig, particularly in Cebu and parts of Mindanao, Lemon basil is used to add flavor to Law-uy, which is an assortment of local greens in a vegetable-based soup. The seeds resemble frog's eggs after they have been soaked in water and are used in sweet desserts. It is also used in North East part of India state Manipur. In Manipur, it is used in curry like pumpkin, used in singju (a form of salad), and in red or green chilli pickles. The Garo, Khasi and Jaintia tribe of Meghalaya also use it in their cuisine. The Garos call it Panet (pronounced Phanet). They use it to prepare cold sauce (Ind. Chutney) with added ingredients like fermented fish, chilly, onions sometimes roasted tomatoes.

When the epidemic is waiting for an opportunity again, to quickly control the spread of the virus, nucleic acid testing has become the only way to go, and it has also attracted attention from all walks of life. However, there are many factors that affect the results of nucleic acid testing, including sample collection location, collection method, storage and transportation process, nucleic acid extraction operation, and so on. Among them, the stability of the sample is a key link. How to quickly inactivate the virus and protect the viral nucleic acid from being degraded, maintaining the stability of the virus sample storage solution has become a top priority. Step 1: Break the shell and eliminate the "combat power" Like other RNA viruses, the results of the new coronavirus are simply composed of a protein shell wrapped in single-stranded nucleic acid-RNA. We can simply think of the RNA of the virus as the "brain" that gives orders, and the protein is the "limbs" that execute orders. The new coronavirus infects the human body and reproduces and causes symptoms. This process is mainly completed by the biologically active protein structure outside the virus. The inactivated virus preservation solution is mainly the virus modified by the nucleic acid extraction lysis solution; it is a powerful protein denaturant that can quickly dissolve the protein and cause the virus structure to be broken. When the clinical sample with the new coronavirus is mixed with the preservation solution, the virus in the sample is affected by the lysis solution, and the protein shell is quickly destroyed, and this damage is irreversible. At this time, the virus has lost its evil "minions" and no longer has the ability to infect people, thus ensuring the safety of contacts during sample transportation and processing. Step 2: Inhibit enzyme activity and escort the "ID card" After the shell is lysed, the RNA of the new coronavirus is free in the preservation solution. As a single-stranded macromolecule, the stability of RNA is not as immobile as double-stranded DNA. The RNase that exists everywhere in the natural environment is the culprit that causes RNA to hydrolyze and break. Therefore, it is generally considered that the viral RNA that has lost its outer shell protection is In addition to the inactivated virus storage solution, the virus preservation solution produced by Desheng also has a non-inactivated virus storage solution. It retains the protein coat of the virus and the viral nucleic acid DNA or RNA at the same time, so that the virus has the integrity of the protein epitope and nucleic acid in vitro. Of course, there is a certain risk of infectivity when operating errors. Long-term storage after sampling needs to keep strictly low temperature. Regardless of the virus preservation solution, we need to strictly operate, store or transport in accordance with the requirements when using it.

The indispensable attribute of the carrot is its richness in provitamin A (called carotene). With a hundred g of carrots, one covers more than half of the daily requirement of nutrition A (carotene turns into diet A in the body). Usually, the most vibrant carrots are also the richest ones in carotene. The carotene content material stays secure at some point of time as it does not trade a whole lot from the time of harvesting and cooking destroys only a small component (10-15% maximum). Carrot, or Daucus carota, is a root vegetable and is recognised to be the best fitness food. It is crunchy, tasty, and extraordinarily nutritious. The largest carrot exporter in India exports large portions of the vegetable every year. Due to its range of fitness and medicinal uses and benefits, the carrot export from India has been growing swiftly over the decades.
