Researchers created transgenic rice with anti-hypertensive peptides that lowered blood pressure in hypertensive rats. The effect remained after a 5-week treatment period without obvious side effects. If effective in humans, it could lead to a daily intake of only half a tablespoon of special rice.
Researchers propose that elevated pulse pressure in blood traveling to the brain can cause inflammation, oxidative stress, and cellular dysfunction, leading to brain damage and cognitive decline. The study suggests reducing elevated pulse pressure could prove synergistic with other therapeutic approaches to treat dementia.
Researchers found that females upregulate anti-inflammatory T cells to maintain lower blood pressures, which may lead to new hypertension treatment strategies for females. In contrast, males did not show a significant response to reduced Treg levels, suggesting their blood pressure is less dependent on this mechanism.
Researchers investigate medication use in older adults, finding that certain hypertension medications may reduce dementia risk and improve stroke outcomes. A deprescribing program also shows promise in reducing falls risk, with primary care providers accepting over 90% of recommendations.
