sons, clay and organic matter differences between soils should be incorporated into any kind of predictive model. Measuring the cation exchange capacity (CEC) for all horizons of Several researchers have attempted to predict CEC every map unit component in a survey area is very time consuming from clay and organic C contents alone, using multiple and costly. The objective of this study was to d...

Earlier studies showed that infection of chick embryo cells (CEC) by strain MC29 avian leukosis virus resulted in virus elaboration and a rapid, uniform morphologic alteration of the cells. No marked difference in the RNA synthesis patterns of infected and noninfected cells could be shown by the use of radioisotope-labeled RNA precursors and density gradient analysis. Treatment of the cultures ...

2044 Background: Bevacizumab (Bev), a monoclonal antibody targeting the vascular endothelial growth factor (VEGF), has shown significant activity in a subset of patients with high grade gliomas (HGG): to date no biological marker can predict the treatment benefit. Circulating endothelial cells (CEC) and progenitors (CEP) have been observed in cancer patients, reflecting ongoing tumor angiogenes...

PURPOSE Procollagen I is synthesized and intracellularly degraded in corneal endothelial cells (CEC), whereas type IV and VIII collagens are secreted into Descemet's membrane. In our previous study, we demonstrated that procollagen I synthesized by CEC is improperly folded and that the molecule was largely colocalized with protein disulfide isomerase (PDI) within the endoplasmic reticulum (ER)....

The rescue of infectious virus from nonproducer BH RSV(-) cells by chick cellular DNA was attempted in order to investigate the functional state of endogenous and exogenous retroviral genes integrated within the cellular DNA. No infectious virus was rescued by transfection with DNAs of chick helper factor (chf)-negative chick embryo cells (CEC), chf-positive CEC or uninfected CEC producing endo...

A hybrid silica monolithic stationary phase for RP CEC was prepared by in situ co-condensation of (3-mercaptopropyl)-trimethoxysilane (MPTMS), phenyltriethoxysilane (PTES), and tetraethoxysilane (TEOS) via a sol-gel process. The thiol groups on the surface of the stationary phase were oxidized to sulfonic acids by peroxytrifluoroacetic acid. The introduced sulfonic acid moieties on the monolith...

A revolutionary approach to air defense has been extensively evaluated recently. The approach is a new Cooperative Engagement Capability (CEC) that allows combat systems to share unfiltered sensor measurements data associated with tracks with rapid timing and precision to enable the battlegroup units to operate as one. The CEC system and the program for Fleet introduction are described. Further...
