What is leukemia?

As we know, blood is essential for life. And in the blood there are many different substances and cells, each of which performs its task. But sometimes the ratio of substances in the composition of the blood for some reason is violated. One such blood disorder is called leukemia.

The number of leukocytes (white blood cells) in the blood of a person with leukemia can increase 50-60 times. This condition is very serious, because it is the result of a malfunction of the organs that produce blood. Previously, a person with leukemia was considered hopeless. And although there is still no cure for leukemia, nevertheless, something has been achieved, especially in terms of prolonging the life of the patient and alleviating his condition.

There are several types of leukemia. Each form has different symptoms and affects a person's lifespan in different ways. Therefore, in each case, a specific treatment is prescribed. Leukemia is divided into two main forms: acute and chronic. Acute leukemia can come on suddenly and progress very quickly. The disease in this form is difficult to recognize until it progresses.

Acute leukemia usually affects people over the age of 35. Leukemia has different forms yet depending on the specific type of white blood cells. But, although there are many varieties of leukemia, the initial signs of the disease can be exactly the same. Therefore, it is very important to make a diagnosis as early as possible. The presence of leukemia is determined by examining the blood and bone marrow under a microscope.

Random interesting fact from the Great Encyclopedia:

What is memory?

Can you remember the alphabet quickly and easily? Is it easy for you to write your name? Can you play the scale on a musical instrument? You may say that you remember all this. But in fact, you have memorized it all. And you learned all this by forming a habit!

In other words, things that were once difficult for you, like naming the letters of the alphabet or playing the scale, become easy and almost automatic when you get into the habit of doing it. Therefore, memory can be described as learning by habit formation. A person has an unimaginable number of such habits, with the help of which he does almost all the daily activities in his life - for example, fastening a button or washing his hands. But imagine that you are reading a book and someone asks you what it is about, or asks you to tell the plot.

Of course, this cannot be called a habit. But if you carefully study the situation, you will see that there is something like a habit. For example, in the usual case, you learn how to arrange certain elements in the appropriate order. And when you retell the plot of a book or its contents, you are doing the same.

Some psychologists believe that all learning (and that also means memory) consists of vast combinations of simple habits. But this does not mean that in the process of learning and remembering, you simply form habits through mechanical repetition or study of some elements.

There are some other factors that influence the situation and allow you to learn and remember better. One of them is the desire to learn, that is, motivation or motivation.

Another important factor is the understanding of what the person is learning. For example, you will quickly learn (or recall) a poem if you understand it. And you will remember it for a long time. In addition, linking new ideas with what is already deposited in your memory can be an important aid in learning.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Logitech MX Anywhere 3 Wireless Mouse 27.09.2020

Logitech has announced the MX Anywhere 3 and MX Anywhere 3 for Mac mice that use a wireless connection to communicate with your computer. In the Russian market, new items will go on sale until the end of September.

Manipulators can connect to a PC in two ways: via Bluetooth Low Energy or via a Unifying RF transceiver with a USB interface. The claimed range reaches ten meters.

The design provides for the presence of an electromagnetic wheel MagSpeed. It provides scrolling up to 1000 lines per second and the ability to instantly stop the cursor at any desired location.

Another advantage of the novelty is the ability to work on almost any surface, including glass. The mouse is not afraid of dust, withstands bumps and drops associated with a mobile lifestyle.

Claimed battery life on a single battery charge up to 70 days. Recharging is done via the USB Type-C port; and one minute of power supply is enough for three hours of work.

The MX Anywhere 3 model is compatible with Windows, macOS, iPadOS, ChromeOS, and Linux. MX Anywhere 3 for Mac is optimized for macOS, compatible with iPad, and comes with a USB-C to USB-C charging cable. The price of both new products will be 90 USD.
