Taking selenium supplements is associated with lower levels of antibodies that attack the thyroid in people diagnosed with autoimmune thyroid disease.
Antibodies that target the thyroid peroxidase enzyme can interfere with its function, leading to decreased production of thyroid hormones.
In some individuals, immune system proteins called autoantibodies bind to the thyroid gland, reducing its ability to produce hormones and triggering persistent inflammation.
Most cases of hypothyroidism occur because the immune system attacks the thyroid gland, and the thyroid naturally holds more selenium than most other tissues in the body.
It is unclear whether selenium supplements help treat Graves' disease because studies have varied widely in how they gave selenium, did not measure patients' initial selenium levels, and used lab...
Taking selenium supplements does not lead to better quality of life for people with Graves' hyperthyroidism who do not have eye symptoms, as studies show no meaningful difference in mood or...
Taking selenium supplements after standard treatment for Graves' disease does not reliably lead to better long-term remission, and blood levels of selenium do not predict whether the disease will...
In patients with mild, active Graves' orbitopathy lasting less than seven months, selenium supplementation may be linked to better quality of life and fewer eye symptoms, but these findings are based...
In people with Graves' disease taking antithyroid medications, adding selenium may lead to faster normalization of thyroid hormone levels at six months, but this effect does not last until nine...
There is no clear evidence that taking selenium supplements improves key outcomes for people with Graves' disease, such as reducing relapses, improving quality of life, or easing eye symptoms.
Taking selenium supplements does not keep thyroid hormone levels improved in people with Graves' disease beyond six months; after nine months, these levels return to what they were before treatment,...
Taking selenium supplements at 100–300 micrograms per day for 3 to 6 months may lead to a small rise in thyroid-stimulating hormone levels in adults with Graves' disease who are on antithyroid drugs,...
Taking selenium supplements daily at 100–300 micrograms for six months may lower levels of antibodies targeting the thyroid-stimulating hormone receptor in adults with Graves' disease who are on...
In adults with Graves' disease taking antithyroid medication, taking selenium supplements at 100–300 μg per day for 3 to 6 months lowers levels of FT3 and FT4 hormones in the blood, but these...
Six chemical compounds were tested from a fungus called Talaromyces purpureogenus. Only one of them, called compound 5, was able to inhibit the growth of Staphylococcus aureus and Mycobacterium...
A crude extract from a fungus inside pomegranates killed the bacterium Staphylococcus aureus in a lab test but had no effect on E. coli or tuberculosis bacteria, suggesting it only works against...
Scientists found that a fungus growing inside pomegranate fruit generated six chemical compounds, two of which had never been seen before, using laboratory techniques to separate and identify them.
Scientists identified two previously unknown chemical compounds from a fungus found inside pomegranate fruit and used computational methods to determine their precise three-dimensional molecular...
A chemical compound called alternariol, extracted from a fungus found inside pomegranates, was shown in laboratory tests to inhibit the growth of both regular and antibiotic-resistant strains of...
Even though monkeys on a low-calorie diet burn less energy while sleeping and eat less, their total daily energy use stays the same because they move around more and spend less energy moving, so it...
Monkeys that eat fewer calories over many years stay more active as they age, while monkeys that eat normally become much less active over time.
Monkeys that eat less over a long time use less energy when they move around, which means their muscles work more efficiently — like a car that gets better gas mileage.
Monkeys that eat fewer calories for a long time tend to move around more and stay active longer than monkeys that eat normally, even though they're taking in less energy.
Monkeys that ate less for many years burn fewer calories while sleeping, even when you account for how much muscle they have, as if their bodies learned to use less energy just to stay alive.
