The cell-mediated immune profile induced by a recombinant DNA vaccine was assessed in the simian/HIV (SHIV) and macaque model. The vaccine strategy included coimmunization of a DNA-based vaccine alone or in combination with an optimized plasmid encoding macaque IL-15 (pmacIL-15). We observed strong induction of vaccine-specific IFN-gamma-producing CD8(+) and CD4(+) effector T cells in the vacci...

S U M M A R Y Mapping the elastic and anelastic structure of the Earth’s mantle is crucial for understanding the temperature, composition and dynamics of our planet. In the past quarter century, global tomography based on ray theory and first-order perturbation methods has imaged longwavelength elastic velocity heterogeneities of the Earth’s mantle. However, the approximate techniques upon whic...

Transcription of T7 and mutant T3 DNA during infections of F plasmid-containing cells has been analyzed by using Southern hybridization. A transcriptional defect is apparent in these abortively infected cells that is most severe in the class III region of the phage genome. In particular, RNAs that are initiated from the gene 13 promoter are not elongated to give full-length molecules. It is sug...

Familial patterns of the occurrence of breast cancer were studied in a population-based case-control series of black women from the Cancer and Steroid Hormone study. The risks of breast cancer among relatives of breast cancer cases were compared to those of controls who were matched for age and locale. Using the term "proband" to indicate either case or control status, significant predictors of...

The characterization of materials supports their development and in particular of superconductors, for their technological applications. Scanning electron microscopy (SEM) is one of these characterization techniques, whose data is used to estimate the properties, determine the shortcomings and hence improve the material. The phenomenon of superconductivity initially develops within the grain an...

B a fundamental attribute of a good theory is causality, the Information Systems (IS) literature has strived to infer causality from empirical data, typically seeking causal interpretations from longitudinal, experimental, and panel data that include time precedence. However, such data are not always obtainable and observational (cross-sectional, nonexperimental) data are often the only data av...
