‘Soy isoflavones possess estrogenic properties that may cause changes in breasts tissue. Animal models suggest that ingestion of soy may result in earlier maturation of breast tissue and increased level of resistance to carcinogens.’ As provocative as the results are, Ziegler cautioned that it might be premature to suggest adjustments in childhood diet. ‘This is actually the first study to evaluate childhood soy intake and subsequent breast cancer risk, and this one result is not enough for a public health suggestion,’ she said. ‘The results have to be replicated through additional analysis.’..Professor Isbister says study in the U.S. Involving 6,000 sufferers undergoing heart medical procedures, has raised serious problems with respect to the shelf lifestyle of bloodstream and its own effects on patients – the study revealed that those that had transfusions using bloodstream that was even more that 2 weeks old had more problems than those that received fresh bloodstream. Professor Isbister believes a patient’s own bloodstream is a very important and unique natural source that needs to be conserved and maintained properly and donated allogeneic bloodstream should only be utilized whenever there are no various other alternatives. Current practice in Australia consists of donated bloodstream being refrigerated and delivered to hospitals and various other health care providers within a fortnight, but under Crimson Cross standards, supplies could be stored for six weeks.
