The association between cerium status and risk of first acute myocardial infarction (AMI) was examined in a case-control study in 10 centres from Europe and Israel. Cerium in toenails was assessed by neutron activation analysis in 684 cases and 724 controls aged 70 years or younger. Mean

Conventional angiography is insufficient for evaluating the therapeutic effect of cardiac regeneration therapy. A microangiographic X-ray system using a cerium anode was developed. Cerium has a characteristic X-ray with a peak at 34.6 keV, which allows visualization of tiny amounts of iodine. The

Cerium has been implicated in the pathogenesis of cardiac disorders such as acute myocardial infarction and endomyocardial fibrosis (EMF). A geochemical hypothesis for the causation of EMF linked the cardiac lesions to magnesium deficiency consequent to malnutrition and increased cardiac levels of

OBJECTIVE Lacunar stroke may be caused by infarction of small perforating branches of the middle cerebral artery. We developed a microangiographic X-ray system using a cerium anode to evaluate the perforating branches. METHODS Iodine has K-edges at 33.2 kilo electron volts. Cerium yields a

One hundred nine dogs subjected to experienced experimental coronary occlusion were retrospectively examined in an attempt to identify factors influencing infarct size. A coronary artery was occluded by an embolus. The field of the occluded artery (zone at risk) was determined by subsequent

Calcium antagonists and evolving myocardial infarction: studies of the effects of nifedipine on tissue ATP, collateral flow and infarct size in the closed chest dog.

In previous studies nifedipine has been shown to limit infarct size during 24 h of regional ischemia in the dog. Using a closed chest embolization procedure, autoradiographic (141-cerium at onset of ischemia) microsphere risk zone analysis and tetrazolium staining, the ability of nifedipine to

Therapeutic effect on experimental acute cerebral infarction is enhanced after nanoceria labeling of human umbilical cord mesenchymal stem cells.

Therapeutic applications of stem cells, especially mesenchymal stem cells, were once regarded as a promising therapy for mitigating acute cerebral infarction. Unfortunately, all the stem cell clinical trials have been futile. A new stroke therapeutic strategy of combining stem cells

Limitation of myocardial infarct size by superoxide dismutase as an adjunct to reperfusion after different durations of coronary occlusion in the pig.

Superoxide dismutase (SOD) has been documented to limit myocardial infarct size in the richly collateralized dog heart. This study was designed to explore this concept in a low-collateralized animal model. A blind, randomized, placebo-controlled protocol was used in 65 pentobarbital-anesthetized

(-)Deprenyl-N-oxide, a (-)deprenyl metabolite, is cytoprotective after hypoxic injury in PC12 cells, or after transient brain ischemia in gerbils.

OBJECTIVE (-)-Deprenyl (selegiline) possesses cyto-protective effect in a much lower concentration, than it is needed to inhibit MAO-B activity. In permanent MCA occlusion stroke model in rats, the infarct volume and the number of apoptotic neurons in the penumbra region were decreased by low
