Multiple imputation of missing blood pressure covariates in survival analysis.
This paper studies a non-response problem in survival analysis where the occurrence of missing data in the risk factor is related to mortality. In a study to determine the influence of blood pressureExpand

The definition of anemia in older persons.
CONTEXT Whether hemoglobin concentrations defined as anemia by the World Health Organization (WHO) are associated with increased mortality in older persons is not known. OBJECTIVE To investigateExpand

Successful aging in the oldest old: Who can be characterized as successfully aged?
BACKGROUND Successful aging is a worldwide aim, but it is less clear which indicators characterize elderly persons as successfully aged. We explored the meaning of successful aging from 2Expand

Isolation and characterization of Kupffer and endothelial cells from the rat liver.
Abstract Non-parenchymal cell suspensions were prepared from rat livers by three different methods based on a collagenase, a pronase and a combined collagenase-pronase treatment. The highest yield ofExpand

Comparative endotoxin‐induced hepatic injury in young and aged rats
Recent studies have demonstrated that aged rats are more susceptible to the lethal effects of endotoxin (ET) than young rats. The early (15 min to 7 h) hepatic ultrastructural and biochemical changesExpand

Association of the tumour necrosis factor α −308G/A polymorphism with the risk of diabetes in an elderly population-based cohort
Ample evidence supports a role for tumour necrosis factor α (TNFα) in the development of type 2 diabetes and cardiovascular disease. TNFα expression was found to be influenced by a −308G/AExpand
