Abstract: An ultrathin-layer chromatography plate including a stationary phase comprising electrospun nanofibers wherein at least about 50% of the nanofibers are oriented within 20° of a direction of alignment, and wherein the stationary phase has a thickness from about 10 ?m to about 30 ?m.

Abstract: A high yield method for chemically synthesizing low polydispersivity carbon microspheres, nanospheres, nanocrystals, nanotubes, or nanofibers comprising dispersing a self-polymerizing end-capped polyyne in a solvent; heating the dispersed self-polymerizing end-capped tetrayne to form a polymeric material selected from the group consisting of polymer microspheres, polymer nanospheres, polymer nanocrystals, polymer nanotubes, and polymer nanofibers; and pyrolyzing the polymeric material to form a carbon material selected from the group consisting of carbon microspheres, carbon nanospheres, carbon nanocrystals carbon nanotubes, and carbon nanofibers, wherein the polydispersivity is less than 2.

Abstract: Cell preparations comprising a plurality of apoptotic EBV-transformed B lymphocytes, and methods of producing cell preparations comprising a plurality of apoptotic EBV-transformed B lymphocytes are provided. The methods comprise transforming B lymphocytes with EBV, incubating the transformed B lymphocytes with a flavin photosensitizer, such as riboflavin or a lumichrome-resistant photosenstizer, adding a non-toxic anti-oxidant, and exposing the lymphocytes to photoradiation of an appropriate wavelength to activate the photosensitizer. Also provided are methods of using the apoptotic EBV-transformed B lymphocyte cell preparations to elicit production of EBV-specific T cells in human patients. Finally, methods of treating organ transplant patients comprising administering an effective amount of the apoptotic EBV-transformed B-lymphocytes cell preparation to the patients prior to transplantation are provided.
