A simple and versatile ternary vector system that utilizes improved accessory plasmids for rapid maize transformation is described. This system facilitates high-throughput vector construction and plant transformation. The super binary plasmid pSB1 is a mainstay of maize transformation. However, the large size of the base vector makes it challenging to clone, the process of co-integration is cumbersome and inefficient, and some Agrobacterium strains are known to give rise to spontaneous mutants resistant to tetracycline...

To improve the potency of anti-human cytomegalovirus (HCMV) immunoglobulin preparations, we intended to find elite neutralizers among 9000 HCMV-seropositive blood donors. We identified 2.6 % top neutralizers using a high throughput screening and further analyzed the 80 most effective plasmas for strain-independent activity. Of those, 58 were broadly neutralizing towards various HCMV strains and hence regarded "elite" neutralizers. All elite neutralizers were then analyzed concerning their effect on individual virus particles during entry...

Vaccination played an important role in the formation of a national consciousness in Cuba, and vaccination's earliest promoters dominate nationalist narratives of medical achievement on the island. This article investigates the intense hostility exhibited by the creole medical elite toward a pivotal figure in the history of smallpox vaccination in Cuba, Spanish physician Dr. Vicente Ferrer (1823-83), the first in the Americas to mass produce smallpox vaccine using calf vaccinifiers. I argue that anger and mistrust of both Ferrer and his innovatory vaccine production technology originated in the relationship between medical politics and cultural identity in late nineteenth-century Cuba...
