Normal human breast lobules, freshly isolated by precision microdissection of tissue stained with methylene blue chloride, were assayed for their ability to induce neovascularization (angiogenesis) in rabbit irises. Histologically, normal lobules from cancerous breast induced angiogenesis twice as often as lobules from noncancerous breasts, suggesting that(More)
An attenuated strain of Vibrio cholerae was used as a carrier for the expression of heterologous antigens such as fragment C from tetanus toxin (TetC) and tracheal colonization factor from Bordetella pertussis (Tcf). In vitro, high levels of protein were obtained when the Escherichia coli nirB promoter was used and the bacteria were grown with low aeration.(More)
A nonapeptide from IL-1beta has been reported to be an immunostimulant and adjuvant. To investigate the possibility of enhancing the immunogenicity of recombinant antigens delivered by live-attenuated Salmonella strains, we inserted an oligonucleotide coding for the nonapeptide from murine IL-1beta into the genes of three model proteins: LamB, MalE, and(More)
Excitotoxicity has been proposed to play a pivotal role in retinal ischemia. Retinal ischemia-associated ocular disorders are vision threatening. The aim was to also examine whether and how S-allyl L-cysteine (SAC) can protect the retina against kainate excitotoxicity. In vivo retinal excitotoxicity was induced by an intravitreous injection of 100 μM(More)
