Antigens by special delivery

Special Delivery

Two months into my intern year I experienced something that I thought only happened on television. It was 3 a.m. on a relatively uneventful night shift. Being one of the newest residents working that evening I expected to get the less desirable cases, and this one felt no different. A new patient showed up on the grease board: a 22-year-old female with a chief complaint of constipation. “Sounds...

Drug Delivery Approaches with Special Emphasis on Chemical Drug Delivery

Special problems in aerosol delivery: artificial airways.

Several factors interact in influencing aerosol deposition during mechanical ventilation. Among these factors, the artificial airway is a significant barrier for aerosol deposition. Earlier studies overemphasized the impediments created by the artificial airway to aerosol delivery, because the aerosol generator was placed adjacent to the endotracheal tube or was connected to it. When the aeroso...

Intracellular motility: A special delivery service

Recent studies have identified a delivery service that operates in specialised cell appendages: two motor proteins and a novel protein organelle use axonemal microtubules as tracks to shuttle essential components to the tips of flagella and the dendrites of sensory neurons.

Identification of protein antigens of group B streptococci, with special reference to the Ibc antigens

The protein antigens of prototypes of five types of group B streptococcal strains were extracted with HCl or Triton X-100, separated by sodium dodecyl sulfate polyacrylamide electrophoresis, transferred to nitrocellulose, and examined by immunochemical staining. The Ibc proteins are shown to consist of at least two distinct protein antigens and their breakdown products. One antigen, the "beta" ...
