The study reveals that female mice develop cardiac hypertrophy when estrogen is blocked, mimicking human conditions. The discovery could lead to a better understanding of the molecular signals causing heart enlargement and potential ways to prevent or reverse it.
Researchers argue that sauropods, like Barosaurus, required a horizontal neck to function on land due to heart size and metabolic rates. This finding contradicts the common depiction of long-necked dinosaurs raising their heads to browse from trees.
Researchers have discovered a dinosaur fossil with a four-chambered heart, similar to those of birds and mammals. The discovery suggests that the dinosaur was warm-blooded, with a high metabolism, and may have had a more complex circulatory system than previously thought.
A team of scientists has discovered a 66-million-year-old Thescelosaurus with a complete fossilized heart, suggesting the dinosaur's circulatory system was more advanced than that of reptiles. The finding supports the hypothesis that dinosaurs were warm-blooded and could have had metabolic rates higher than typical reptiles.
Researchers at Kanagawa University have invented a technique to store human organs for up to 10 days using the natural preservative trehalose. The method involves flushing organs with trehalose solution and storing them in silica gel, allowing for longer-term preservation without significant tissue damage.
Researchers at Duke University have found that transplanted skeletal muscle cells can mimic heart muscle, significantly boosting the ability of damaged hearts to contract. The therapy has the potential to augment current treatments and prevent further damage.
