Currently, if you want to measure someone's blood oxygen levels, you have to use one of those oximeters that clips onto their finger. An experimental new system, however, is able to check those levels anywhere on the body – and that could mean big things for the field of medicine. Tra...
Iron is toxic because it stimulates the formation of reactive oxygen species, e.g. via the Fenton reaction. Ferritin is the main iron storage protein that protects cells from iron toxicity [8]. An increase in cell iron level leads to increased ferritin synthesis for storing excess iron and a...
The advent of functional magnetic resonance imaging (fMRI) of blood oxygen-level dependent (BOLD) signal acquisitions enabled the inference of functional neuroanatomical circuit responses to affective stimuli19,20,21,22,23,24,25. However, a critical methodological step in these experiments, often omitt...
The Special Protection Group (SPG) personnel ,which is in charge of Prime Minister’s security conducted inspection at BJP National Council Meet venues ahead of Prime Minister Narendra Modi’s visit . The team assisted by city police commissioner and intelligent officers took stock of the situation...
A number of factors drive these changes in protein structure including inflammation, reactive oxygen species, endothelial dysfunc- tion and increased endothelial permeability, as well as activation of certain enzymes such as matrix metalloproteinases.2–5 All these additional factors can also be measured...
Make No Mistake, there is a "best" way to breath. "Nasal inhalation" is the best way--It is more diaphragmatic requiring less muscle effort and thus more of the inhaled oxygen is used elsewhere in the body. However, "shutting your mouth" is obligatory for efficient and effective "nasal ...
The researchers used software to transform the built-in camera of a smartphone into a hyperspectral imager that reliably measures hemoglobin levels (a measure of the oxygen-carrying capacity of blood) without the need for any hardware modifications or accessories. A pilot clinical test with volunteers...
From its location within Earth's orbit, IBEX has sampled interstellar hydrogen, oxygen, and neon in addition to neutral helium. Our heliosphere is the region of space dominated by the Sun and is inflated, like a bubble, in local interstellar material by the million mile-per-hour solar wind....
Oxygen was always higher than 60%. Controls were within the OECD guidelines. Controls showed always absence of NH4+ both at the beginning and at the end of the test. Lakes Candia and Mergozzo, and Sos Canales and Posada reservoirs had a final NH4+ concentration of 7.74 mg·L−1, while...
