| estimation of missing cone data in three-dimensional electron microscopy. | the range of tilt angles for which projected images of two-dimensionally periodic specimens can be obtained in electron microscopy is limited both by technical aspects, such as goniometer design, and by the more fundamental limitation of object thickness. the lack of a full set of projections causes a missing cone in the reciprocal space data for the object, which will give an anisotropic resolution in a three-dimensional reconstruction and may cause the quality to be impaired by spurious featur ... | 2011 | 3244969 |
| unilateral hepatic duct obstruction. | experience with unilateral hepatic duct obstruction is limited. we reviewed 33 cases of unilateral hepatic duct obstruction from a total of 500 patients with biliary reconstruction treated between 1965 and 1984. the median age of the patients reviewed was 56 years. the most common cause of unilateral hepatic duct obstruction was operative injury (73 percent of patients). including operations for unilateral obstruction, patients in the series underwent 131 operations related to biliary tract prob ... | 2010 | 3799897 |

| metabolism of extracellular phospholipids in tetrahymena pyriformis. | we studied the metabolism of phospholipids exogenously added to cultures of the protozoan, tetrahymena pyriformis. tetrahymena cells were found to metabolize the extracellular phospholipids and the fatty acyl chains of the latter were accumulated predominantly as a form of triacylglycerol in the cells. this metabolism was considered to be initiated via endocytosis of phospholipid vesicles, as judged from the following facts: cytochalasin b, an inhibitor of endocytosis, suppressed the metabolism ... | 2011 | 3115965 |
