    “…METHODS: Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria in microbial culture medium were added to reverse spin bioreactors that contained different concentrations of each ZnO type to enable dynamic mixing of the bacteria-ZnO suspensions. Optical density of the bacteria-ZnO suspensions was measured in real-time and the number of viable bacteria after 24 h exposure was determined using standard microbiological techniques. …”

    “…An MRI revealed a 3.0 x 3.8 x 4.4 cm tumor that compressed the optic chiasm. Additionally, multiple lesions were seen within the dural and leptomeningeal extra-axial areas including the largest left frontal lesion of 2.4 cm and a 1.7 cm lesion posterior to the cord within the foramen magnum. …”

    “…Although the gallium-68 radiochemistry of the bombesin conjugates did not show radiochemical incorporation suitable for in vivo studies, likely because the presence of the peptide changed the behavior of the TPP-NH(2) synthon taken alone, the optical imaging assays indicated that the conjugated peptide tags do mediate uptake of the porphyrin units into cells.…”
