When they do , they expose their ' lipid core ' contents to the bloodstream , potentially provoking a clot that can cause a heart attack .
当它们破裂时,内部的“脂质核”将暴露在血液中,可能会形成诱发心脏病的血栓。
Szostak and his team already have a stripped-down system for making tiny hollow spheres , or vesicles , from simple lipid membranes . And lean and mean genetic material is available from simplified versions of today 's rna .
In the action to control cardiovascular risk in diabetes ( accord ) lipid trial , published on-line in the new england journal of medicine , the group with atherogenic dyslipidemia had 70 percent more cardiovascular events ( cardiovascular death , heart attacks and strokes ) than patients without .
Further modifications , such as the removal of lipid a synthesis machinery ( a component of the highly immunogenic lipopolysaccharide ) , made the bacteria even safer and less likely to spread in the host while still retaining the ability to occupy the necrotic lesions of tumours .
When the researchers added radioactively labeled arsenate to the bacteria 's culture , they were later able to discern its presence in the protein , lipid , nucleic acid , and metabolite fractions of the cells , suggesting that arsenic had been incorporated in molecules forming each fraction .
In a paper in trends in endocrinology and metabolism they argue that insulin resistance is another side-effect of metabolic syndrome whose cause is lipid molecules poisoning tissues in which they are not supposed to be present in large quantities .
