I love knowledge and it’s exciting that a meta-analysis in JAMA Internal Medicine has concluded that a vegetarian diet is perfect for decreasing blood pressure!Meta-analysis of research data is the assessment of a multiple research papers related to the same issue and sometimes the meta-analysis can disprove existing assumptions, in this case the meta-analysis confirms what many already thought!
Plus, researchers found that “the effect sizes are similar to those observed with commonly recommended lifestyle modifications, such as adoption of a low-sodium diet or a weight reduction of 5 kg, and are approximately half the magnitude of those observed with pharmaceutical therapy,” they wrote in the study. A weight reduction of 5 kilograms is equivalent to about 11 pounds.

Researchers have found a way to get blood from skin cells, no not by cutting people. More specifically they can use skin cells to produce blood – something that was thought impossible. This will have huge positive effects on people requiring blood treatments.
Among the first applications McMaster will pursue is to eliminate the need for bone-marrow registries that seek to match cancer patients to donors against very long odds. Instead, the new process could turn patients into their own ideal donors, said McMaster vice-president and dean of health sciences John Kelton, himself a hematologist.
The director of Canada’s Stem Cell Network said the McMaster discovery is significant and could soon lead to what called “personalized blood cells”.
It is also important because it suggests skin cells can be converted into other types of cells, such as muscle or pancreatic cells, said Michael Rudnicki.

A new cuff can help save heart attack victims by limiting blood flow.
Ischemic preconditioning involves using the device to interrupt blood flow in the arm, off and on over a period of 35 to 40 minutes: the cuff is inflated for five minutes, then deflated for five minutes, with the procedure being repeated consecutively four times.
Once at the hospital, the patient receives routine heart attack treatment, including cardiac angioplasty. Preconditioning using the cuff may still be going on throughout this procedure, which uses a tiny inflatable balloon to open up narrowed or blocked blood vessels to the heart.
Researchers, whose paper appears in Friday’s issue of The Lancet, found that those heart attack patients randomly assigned to have preconditioning had an overall reduction in heart muscle damage of 30 per cent, compared to those not treated with the cuff.
