To predict a heart attack, droplets of blood stop

08.04.2012

Scientists from the Institute of Translational Medicine. E. Scripps began testing a new test that can detect an imminent heart attack. A simple test predicts a possible heart attack using a sample of blood and cells that slough off damaged blood vessel walls.

This invention closes a major gap in the diagnosis of cardiac diseases. Today, doctors can detect a heart attack only when it has already happened. Yet each year, tens of thousands of patients, even after stress tests in the doctor's office, face the devastating effects of a life-threatening heart attack a few weeks later.

A heart attack occurs after an atherosclerotic plaque ruptures in an artery. The result is a clot that blocks blood flow to the heart. Thus, damage to the tissues of the heart occurs, often life-threatening for the patient, especially when it comes to rupture of cholesterol plaques. In the latter case, the disease is often asymptomatic, and a heart attack occurs unexpectedly. The new test solves this problem, i.e. know in advance about the increased risk of damage to heart tissue. Now the doctor will be able to find out about damage to the endothelium (a layer of cells on the inner surface of blood vessels) even before the formation of a dangerous blood clot and prevent a heart attack or stroke.

Unfortunately, the new test does not yet allow you to accurately determine when exactly an attack will occur: in a day, two or a week. Therefore, people at high risk will have to be tested regularly. Currently, scientists are discussing the possibility of creating a portable device that can quickly detect circulating endothelial cells that indicate damage to blood vessels.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Household DNA analysis and pollution level sensor 26.10.2013

Specialists from the Japanese company Hamamatsu Photonics have developed a sensor that allows you to analyze DNA and monitor the level of environmental pollution at home.

To analyze DNA using a new sensor, quite a bit of blood is enough - about as much as a mosquito sucks. As for pollution, the sensor allows you to monitor the level of radiation and particulate matter (PM2.5). The sensor is a photomultiplier that converts the photon flux into an electrical signal and amplifies it. However, it is not made in the form of an electrovacuum device, as usual, but in the form of a microelectromechanical system (MEMS).

A photomultiplier tube is a key element of a fluorometer, a device that allows you to determine the presence of a specific substance in a sample. The sensor operates in the wavelength range from 300 nm (UV) to 850 nm (near IR). In addition, it can measure the intensity of ionizing radiation, for which you need a scintillator - a substance that emits light under the influence of ionizing radiation. Since the number of emitted photons is approximately proportional to the absorbed energy, in order to estimate the radiation intensity, it is enough to obtain the energy spectrum of the light radiation of the scintillator, which the sensor does an excellent job of.

An idea of the dimensions of the sensor, which the developers called Micro PMT, is given by an illustration. For comparison: miniature photomultipliers currently produced are cylinders 1,5 cm in diameter and 5 cm high. Another advantage of Micro PMT is its immunity to vibration and shock, which allows the sensor to be used in mobile devices. The areas of application of Micro PMT are medical devices, including personal ones.

The manufacturer plans to offer two models, one of which will have a built-in power supply. In the manufacture of sensors, semiconductor production technologies are used, due to which their cost is low. The trial sample costs approximately $620.
