Prediction of clinical efficacy, toxicity, and drug-drug interactions may be improved by accounting for the intracellular unbound drug concentration (Cunbound) in vitro and in vivo. Furthermore, subcellular drug distribution may aid in predicting efficacy, toxicity, and risk assessment. The present study was designed to quantify the intracellular Cunbound and subcellular localization of drugs i...

The development of MT system design is described in four periods: the early experimental period (1946-54), the period of large-scale research on 'direct translation' systems (1956-66), the period after the ALPAC report in which the 'interlingual' and 'transfer' approaches were developed (1966-75), and the current period in which interactive systems and 'artificial intelligence' approaches have ...
In 1956, Goldberg (1) described the probability of developing cancer during two time periods—1940 and 1950. To compute probabilities, data on cancer morbidity and mortality from 1942-1944 and 19491951 were combined, respectively, with life-table data for the three year-periods 1939-1941 and 1949-1951. The analysis was based on the population of upstate New York (New York State exclusive of New ...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
