backgrounds: bleomycin (blm) has been labeled with radioisotopes and widely used in therapy and diagnosis. in this study blm was labeled with [62zn] zinc chloride for oncologic pet studies. materials and methods: the complex was obtained at the ph=2 in normal saline at 90 ° c in 60 min. radio-tlc showed an overall radiochemical yield of 95-97% (radiochemical purity > 97%). stability of complex ...

We describe a technique that uses biocompatible chemical agents to enhance both the sensitivity and the resolution of in vivo imaging with low-level light-emitting probes. We demonstrate experimentally, with chemiluminescence (CL) imaging in vitro as an example, that the detected intensity of CL from treated 3-mm-thick skin tissue is approximately fivefold stronger than that from untreated skin...

We show that phase-conjugation by three-wave mixing allows turbidity suppression through biological tissues with thicknesses up to 5 mm, at a near-infrared wavelength included in the therapeutic window. Because of the ultrafast character of the imaging process, a motion of the tissue, which mimics in vivo imaging, can be exploited to significantly improve the signal-to-noise ratio and the resol...

To gain insight into the dendritic structural changes that occur within minutes of ischemia, as well as circuit-level plasticity that occurs over days to weeks, it is necessary to devise stroke models for anesthetized transgenic mice that are compatible with in vivo imaging methods. In particular, we are interested in examining events during the first few minutes of ischemia that are associated...

Two mitochondria-targeted real-time probes were presented, which could selectively respond to hypochlorite over other ROS. Meanwhile, the "off-on" probes could be successfully applied in the in vivo imaging of hypochlorite in living mice.

Among the various anions, only cyanide induced the revival of fluoresecence of -Cu(2+) resulting in "Off-On" type sensing of cyanide, which can be monitored at pH 7.4 in 100% aqueous system, and has been applied to a microfluidic platform, in which fluorescent sensor -Cu(2+) displayed green fluorescence upon the addition of cyanide, the in vivo imaging of cyanide using Caenorhabditis elegans.

Herein, we describe a fast and robust method for achieving (68)Ga-labelling of the EGFR-selective monoclonal antibody (mAb) Cetuximab using the bioorthogonal Inverse-electron-Demand Diels-Alder (IeDDA) reaction. The in vivo imaging of EGFR is demonstrated, as well as the translation of the method within a two-step pretargeting strategy.
