he Cancer It is the second leading cause of death worldwide and one of the keys to reducing these rates is early detection. A. was created at the University of Technology in Sydney, Australia device which analyzes blood cells to determine the stages of the disease.

“Managing cancer by assessing tumor cells in blood samples is much less invasive than taking a tissue biopsy. It allows doctors to repeat the analyzes and observe the patient’s reaction to the treatment,” says university professor Majid Varkian.

How does it work

Static droplet microfluidic This is the name of the device that can analyze circulating tumor cells that have been separated from the primary tumor and entered the blood.

For its operation, the device uses the unique metabolic pattern that cancer has and thus distinguishes tumor cells from blood cells. Thanks to this filter, the process optimizes detection time, which using other methods can take longer and cost more.

“A single cancer cell can exist among billions of blood cells in just one milliliter of blood, so it is very difficult to find. The new detection technology has 38,400 cameras that can isolate and classify metabolically active tumor cells,” said Varkian.

Another key feature of the device for identifying cancer cells is that it uses pH-sensitive fluorescent dyes to monitor increases in lactate in the body, as tumors produce more of this type of substance.

Thanks to the use of this device, they found a solution to one of the biggest problems of cancer – metastasis. By studying the cells taken from a blood sample, information is obtained about the movement of the disease and its forms, which help to develop new treatments.

Those responsible for this project want to bring it to medical centers, clinical and research laboratories, so that doctors can “diagnose and monitor cancer patients in a practical and profitable way”, because of the high costs and time generated by current tests. technologies.

To achieve this, the university prepares a provisional patent for the device and thus begins to market it.

The dangers of electronic cigarettes

Research from the University of Southern California School of Medicine in the US has provided new evidence to support this electronic cigarette They have negative long-term health consequences.

The researchers found that vapers And smokers have similar levels of damage DNA, twice as much as non-smokers.

These devices heat a liquid to create aerosols that the user inhales. So-called e-liquids may or may not contain nicotine (but not tobacco), but they also often contain additives, flavors and chemicals that can be toxic to human health, the World Health Organization (WHO) has warned.

In the study, people who consumed mint- or fruit-flavored liquids showed the highest levels of DNA damage in the supplements.

In addition, they explained that DNA damage is generally associated with serious diseases such as Cancer oral cavity, which was first observed in pipe smokers in the past and later in cigarettes.
