Wounds heal faster

03.12.2012

Poor wound healing from diabetic ulcers and other diseases places a heavy burden on the family budget, increasing health care costs. The University of Michigan conducted a series of studies that led researchers to new, effective treatments.

It turns out that the same glands that make us sweat are also responsible for another vital job for your health: they help heal wounds. Human skin is rich in millions of exocrine sweat glands that help the body cool down after going to the gym or walking on a hot day. These same glands also play a key role in the healing of skin wounds such as scratches, burns and ulcers, according to new research by scientists from the University of Michigan.

"The treatment of chronic wounds, pressure sores and ulcers, including those caused by diabetes, costs tens of billions of dollars a year in the United States alone, and this amount only continues to grow. Something is not working," says Dr. Laura Ritty, professor of dermatology at University of Michigan School of Medicine.

Now researchers believe they have discovered one of our body's most powerful secret healing tools. The classic understanding of wound healing is that new skin cells come from hair follicles and from intact skin at the edges of a wound. Research results show that cells appear from under the wound. It is hypothesized that human exocrine sweat glands also store a number of adult stem cells that can quickly get to work to help heal.

“At first glance, it seems strange that such an important function of the sweat glands has not yet been discovered,” says Dr. Ritty. “However, there is a reason for this - exocrine sweat glands have not been sufficiently studied, since they are absent in laboratory animals, which are usually used for research. We have found that the human skin heals in a special way. The regenerative potential of the sweat glands has been one of our body's biggest secrets. Our research has of course already advanced our understanding of the healing process, and will hopefully pave the way for better targeted therapies." .

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Blueberry crop improvement robot 28.07.2022

La Libertad is one of the regions producing and exporting more blueberries to Peru. However, the producers of this highly valued sour fruit in the world face a big problem: to determine the exact moment when the mass harvest of blueberries should begin. Errors in forecasts inflict many economic losses on the agro-industrial complex.

With this in mind, the Labinm Robotics research team from the private university Antenor Orrego (UPAO) is developing a prototype robot that allows you to sample a bunch of blueberries and use algorithms and artificial intelligence to know when the fruit should be ready.

“Agro-industrialists have their own harvest forecasts and therefore hire a lot of people for this period, but when the calculations do not work, you have to wait, and the cost of personnel and equipment still has to be assumed, which is why we decided to develop this prototype to give a solution,” said Sixto. Prado Garini, principal investigator at Labinm Robotics.

The specialist stated that the prototype, which is still under development in the laboratory, has four motorized wheels driven by calibrated, customizable and electronically supplemented by other cards, based on the power consumed by these elements.

In addition, it has two high-tech sensors that virtually capture the environment and assign a mathematical representation that allows you to direct work to the growing area to analyze the color and maturity of the fruit.

If there are 5000 blueberries on a bush, the robot will determine that 40% are ready for harvest in a week, and the rest in a week and a half. This is how he takes samples from the crop field and then we extrapolate the results. Said information is sent through the web application or satellite application because we provide industry 4.0 characteristics to it, and is sent to the company's managers for them to make a hiring decision.

Prado Garini assures that the goal of the technological projects he leads is not to destroy the work, but to complement and turn it into an improvement of the industry.
