May 2, 2024 Blood vessels in the lungs aren't like the others in the body. This difference becomes clear in pulmonary hypertension, in which only the lungs' blood vessels stiffen progressively, leading to chronic lung disease, heart failure and death. The underlying reasons for this organ-specific vessel stiffening remained a mystery until researchers made a surprising discovery about these blood vessel ...

May 2, 2024 Two complementary research articles reveal that central and peripheral circadian clocks coordinate to regulate the daily activity of skin and muscles. The coordination between the two clocks (central and peripheral) guarantees 50% of the circadian functions of tissues, including vital processes such as the cell cycle, DNA repair, mitochondrial ...

May 1, 2024 When adults became angry after remembering past experiences, the function of cells lining the blood vessels was negatively impaired, which may restrict blood flow, according to a new study. Previous research has found that this may increase the risk of heart disease and stroke. In this study, episodes of anxiety and sadness did not trigger the same change in functioning of the blood vessel ...

May 2, 2024 Some neurological disorders can be improved through photobiomodulation, a non-invasive technique based on the application of low-intensity light to stimulate altered functions in specific regions of the body. Now, a study reveals how photobiomodulation applied to the brain-gut axis is effective in recovering some cognitive alterations and sequelae caused by chronic stress. The study opens up new ...

May 2, 2024 A new device for taking blood samples uses microneedles and a suction cup instead of a large needle. People with a phobia of needles stand to benefit. More blood can be obtained than with the classic finger prick, making diagnostic measurements more reliable. Because the device can be produced at low cost, it is also suitable for developing ...
