Using Apple Vision Pro during surgery 16.03.2024

The medical team at Cromwell Hospital in London used Apple Vision Pro for the first time during two spinal surgeries. This event confirms the headset's potential as a medical tool that will change the way surgical practice is performed. Although the doctors themselves did not use Vision Pro, the operating room nurse worked with virtual reality using glasses while preparing and performing procedures. The headset made it possible to view virtual screens in the operating room, select instruments and monitor the progress of the operation. Software developed by eXeX, a company that specializes in creating artificial intelligence-based applications for surgery, has significantly improved the patient care process. Using Apple Vision Pro opens up new opportunities for developing healthcare applications such as clinical education, surgical planning, training and medical imaging. Implementation of Apple Vision Pro in the medical industry ... >>

Carbon storage in the North Sea 16.03.2024

Norwegian Energy Minister Terje Åsland has announced the launch of the Longship project, which aims to create a central carbon dioxide storage facility in the North Sea. This ambitious project is valued at $2,6 billion and aims to apply CCS (carbon capture and storage) technology to mitigate the impact of climate change. Norway already has experience in CCS, thanks to the successful Sleipner and Snohvit projects, and is now looking to increase the amount of carbon sealed beneath the seabed. Longship's plan calls for capacity to capture and store 1,5 million tons of carbon annually over 25 years. Despite the positive outlook, there are concerns about the long-term consequences of such storage. However, proponents of the project argue that offshore carbon storage has a number of advantages, including minimal environmental impact. The Longship project is carried out with the participation of Equinor, Shell and TotalEnergies through the joint venture Northern Li ... >>

Mini-organs grown from human amniotic fluid 15.03.2024

An international team of scientists led by Professor Fan Xiulin from Zhejiang University has developed a unique method of growing mini-organs from cells found in human amniotic fluid. This significant medical breakthrough could lead to improved diagnosis and treatment of congenital diseases. The organoids, which are three-dimensional cellular structures that mimic organs on a smaller scale, were grown from lung, kidney and small intestine cells found in amniotic fluid. This method opens up new possibilities for studying various fetal conditions and may be the key to early diagnosis and treatment of birth defects. Although no treatment has yet been attempted, the scientists hope their research will help combat the serious congenital diseases that affect millions of newborns each year. This breakthrough could change medical interventions by making it possible to diagnose and treat congenital diseases. ... >>

Macrophages under hypoxic conditions 02.06.2019

Infected tissue has a low concentration of oxygen. In such a case, the body's standard immune mechanisms dependent on oxygen can only function to a limited extent. How does the immune system, however, control bacteria under such conditions? The researchers found that the citric acid cycle under hypoxic conditions produced fewer metabolites, resulting in a reduced rate of bacterial multiplication in macrophages.

Macrophages are a type of phagocyte and belong to the innate immune system, where they play a key role in defense against intracellular pathogens such as those that cause tuberculosis, legionnaires' disease, or Q fever. The research team observed changes in the mitochondrial metabolism of macrophages caused by signaling pathways initiated by lack of oxygen (hypoxia). This results in a reduction of various metabolites in the citric acid cycle, especially citrate, which in turn prevents bacteria from multiplying as citrate is an important growth factor for some bacteria.

"Our results describe an oxygen-independent pathogen control method that we did not know about until now," explains Prof Jancz from the University of Regensburg. The discovery of these signaling pathways provides new opportunities to fight infectious diseases, the researchers say.
