Eating earlier in the day for 4 days increased the activity of two genes related to cellular repair and longevity in the morning for overweight people compared to eating throughout the day.
Eating earlier in the day for 4 days changed the activity of several genes that control the body's internal clock in overweight people.
Eating earlier in the day for 4 days slightly increased ketone levels in the morning for overweight people compared to eating throughout the day.
Eating earlier in the day for 4 days slightly increased both 'bad' and 'good' cholesterol levels in the morning for overweight people compared to eating throughout the day.
Eating earlier in the day for 4 days made the body more responsive to insulin in the morning, as shown by lower insulin resistance scores and increased expression of a key insulin signaling gene.
Eating all meals within a 6-hour window in the morning and early afternoon for 4 days lowered average blood sugar levels and reduced spikes in blood sugar throughout the day in overweight people compared to eating over a 12-hour window.
When this iridium compound is exposed to special hydrogen gas, its hydrogen atoms show enhanced signals in NMR tests, which is a sign of polarization transfer.
The binuclear iridium compound doesn't work for hyperpolarization by itself, but when mixed with the active catalyst, it can help transfer polarization to pyridine molecules.
This iridium compound is easy to make, stable in air, and works better for hyperpolarization than the more complicated carbene-based catalysts usually used for this purpose.
In the binuclear iridium compound, different pyridine molecules swap places at different speeds, which seems to be related to how tightly they're attached to the iridium atoms.
A different iridium compound doesn't work well for hyperpolarization at room temperature because it holds onto pyridine too tightly, but it shows a little activity when warmed up.
The binuclear iridium compound can swap hydrogen atoms in pyridine molecules at specific rates, with the ortho position exchanging fastest.
Over time, the iridium compound changes into a different structure that can swap hydrogen atoms in molecules, which is useful for making labeled compounds for medical imaging.
When this iridium compound is used with special hydrogen gas, it can make NMR signals for pyridine much stronger—over 200 times stronger in some cases.
The iridium compound has parts that move around quickly at room temperature, with pyridine molecules leaving at about 8 times per second and hydrogen atoms swapping positions about 3.6 times per second.
The iridium compound loses a pyridine molecule to form a simpler structure that helps transfer polarization during the SABRE process.
A special iridium compound can make NMR signals much stronger for certain molecules like pyridine by using hydrogen gas, making it easier to detect these molecules in scientific tests.
