    “…Butyl-Methyl Methacrylate (BMMA) plastic was adopted as it preserves excellent tissue morphology and can be de-plasticized easily using an organic solvent, which enables immuno-staining of serial-sections without antibody penetration issues over millimeters of 3-D reconstructed tissue (Z-depth). …”

    “…RESULTS: The results showed that it was found that PI3K gene expression on breast cancer tissue was higher than the number in a benign tumour (fibroadenoma mammae) as an endogenous control. And also, the expression of RhoC is much lower on breast cancer tissue compared with a benign tumour. …”

    “…In medical applications, especially in positron emission tomography (PET), better time of flight (TOF) information of the emitted gammas leads to a higher signal-to-noise ratio in the reconstructed image. …”

    “…We tested state-of-the-art devices from Fondazione Bruno Kessler and measured a best CTR of 51 ± 5 ps full width at half maximum when coupling 2 mm × 2 mm × 3 mm BaF2 crystals excited by 511 keV electron–positron annihilation gammas. Using these vacuum ultraviolet SiPMs we recorded the scintillation kinetics of samples from Epic Crystal under 511 keV excitation, confirming a fast decay time of 855 ps with 12.2% relative light yield and 805 ns with 84.0% abundance, together with a smaller rise time of 4 ps beyond the resolution of our setup. …”
