Mushrooms can increase Vitamin D

Eating three or four button mushrooms a day is sufficient to make vitamin D for the average person’s estimated daily needs, according to an Australian scientist.
Professor Rebecca Mason, head of physiology at Sydney Medical School and past president of the ANZ Bone and Mineral Society has found that like humans, button mushrooms also need exposure to sunlight for the photochemical manufacturing to kick into action, News.com.au reported.

Mason said that button mushrooms need two hours unwrapped on a plate in the midday summer sun and a bit longer in winter to get the vitamin D boost, and placing them a couple of extra hours in the shade will allow time for the full chemical reaction.
Mason said that eating three or four button mushrooms every day is enough for active people, while people who are housebound could up their dose of button mushrooms to increase their levels of vitamin D.
BP drug may help slow coronary disease

 Patients suffering from clogged and hardened arteries, who already have their blood pressure under control could benefit from blood pressure-lowering medication aliskiren, a new study has claimed.

According to research from the Cleveland Clinic Coordinating Center for Clinical Research, the renin-inhibitor aliskiren tended to slow coronary disease progression and reduced the risk of death, stroke and heart attack in these patients by about 50 percent, compared to placebo, suggesting that patients with prehypertension may benefit from blood pressure lowering drugs. Aliskiren affects the body’s renin-angiotensin-aldosterone system (RAAS), a hormone system that regulates blood pressure and has been shown in prior studies to play an important role in the development of atherosclerosis, or the hardening or clogging of the arteries.

 As a renin inhibitor, aliskiren partially blocks renin from triggering the RAAS process and is approved to treat hypertension to optimal guidelines of 140/90 mmHg, or the high end of the prehypertensive range.

A team of researchers led by Stephen J. Nicholls, M.D., Ph.D., senior consultant to Cleveland Clinic’s C5Research and Professor of Cardiology and Deputy Director at the South Australian Health and Medical Research Institute (SAHMRI) in Adelaide, Australia, used intravascular ultrasonography (IVUS) to assess the degree of coronary disease progression in 458 patients at baseline and after 104 weeks of treatment with aliskiren or placebo.

IVUS is a medical imaging technology in which a small ultrasound probe is inserted via a catheter into an artery, allowing physicians to examine the inside of arteries via sonogram.

Stem cell implants can help resynchronise cardiac motion

Researchers have discovered a method to resynchronize cardiac motion following a heart attack with the help of stem cells.

Scientists implanted engineered stem cells, also known as induced pluripotent stem (iPS) cells, into damaged regions of mouse hearts following a heart attack. This regenerative approach successfully targeted the origin of abnormal cardiac motion, preventing heart failure.

Andre Terzic, M.D., Ph.D., senior author of the study, said that the discovery introduces - for the first time - stem cell-based ‘biological resynchronization’ as a novel means to treat cardiac dyssynchrony.

Muscle damage following a heart attack may disrupt normal heart conduction, resulting in a condition known as cardiac dyssynchrony.

Stem cell-based repair is going to offer a new solution to patients who would otherwise be resistant to device-based resynchronization.

Satsuki Yamada, M.D., Ph.D., first author of the study, said that a high-resolution ultrasound revealed harmonized pumping where iPS cells were introduced to the previously damaged heart tissue.
