Oversalted food harms the vessels of adolescents

09.05.2017

Dr. Elaine M. Urbina, of the Cincinnati Children's Hospital, and her colleagues presented the results of a new study on whether excessive salt in the diet of teenagers and young men affects their artery walls. Young people who eat too much salt have measurable changes in their blood vessels associated with early signs of cardiovascular disease, according to new data.

Arterial stiffness, also known as arteriosclerosis, is a known risk factor for heart attack and stroke in adults. Sensors placed on the skin near large arteries in the shoulder, neck, and groin can detect this condition, which indicates an increased risk of heart attack and stroke.

Increased arterial stiffness, according to recent studies, is also observed in young people with risk factors such as obesity, diabetes, hypertension and high cholesterol.

The study involved 775 people recruited at Ohio State Children's Hospital. They measured the elasticity and distensibility of their brachial artery (BrachD), as well as pulse wave velocity (PWV) - to determine the differences in the speed of blood flow between the carotid artery in the neck and the femoral artery in the groin. The amount of salt was estimated from the reports of the participants, which were compiled three times a day.

The results showed that higher average daily salt intake was associated with lower BrachD and higher PWV, after adjusting for age, race, sex, body mass index, and other factors that could influence measurement results.

"Together, these two indicators showed higher levels of stiffness in both the peripheral arteries in the extremities and in the central arteries associated with increased salt intake," Urbina said. "It is clear that adolescents and young adults have higher than recommended amounts of salt in your diet. Our study suggests that this may lead to changes in the body that increase the risk of future heart attack and stroke."

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, ... >>

CC3200 - Cortex-M4 microcontroller with built-in WiFi 09.08.2015

The new CC3200 system-on-a-chip from Texas Instruments includes a fully functional WiFi core and a powerful 4 MHz Cortex-M80 microcontroller and a wide range of familiar peripherals. The chip allows you to create complete devices of the Internet of things, using a WiFi network to access the Internet and a variety of wired interfaces to communicate with the outside world.

All resources of the built-in microcontroller are available for the user application - 4-channel 12-bit ADC, 4x16-bit timers, UART, SPI, I2C and SD/MMC interfaces. The multimedia capabilities of the chip include a serial interface for I2S audio transmission and a parallel interface for connecting a video camera. To achieve high data processing speed, the chip has a direct memory access controller (32-channel DMA) and a hardware accelerator for protecting transmitted information - an AES-256 encryption unit.

Applications for CC3200:

Smart home and intelligent building;
Security and access control systems;
Industrial telemetry and wireless sensors;
Wireless transmission of sound and video;
Intelligent power supply networks (SmartGrid);
Access to the Internet and cloud services for any embedded device.

The CC3200 Wi-Fi subsystem includes a separate ARM core that performs all wireless data transfer tasks in a transparent mode for the user and does not require the resources of the Cortex-M4 microcontroller, which is completely at the disposal of the developer. From this point of view, the CC3200 can be viewed as a CC3100 chip to which an external microcontroller with a Cortex-M4 core was simply added. The CC3200 WiFi radio operates in the 802.11 b/g/n standard and can act as both a base station ("distribute the Internet") and act as a client, connecting to any regular WiFi router. The air speed is up to 72 Mbps, while the real data transfer rate reaches 12 Mbps in TCP connection mode.

The CC3200 differs from other similar solutions by supporting a larger set of secure WiFi network connection modes and provides a reliable secure connection based on TLS/SSL protocols.

The undoubted advantage of the CC3200 is the ecosystem created by Texas Instruments, which includes Wi-Fi and TCP / IP protocol stacks built into the chip, inexpensive debugging tools, sample programs for typical WiFi tasks, and open development of finished WiFi devices for which a complete schematic, list of elements, PCB layout and source code of the executable program.
