Abstract
![]()
Bone sarcomas are devastating primary bone cancers that
mostly
affect children, young adults, and the elderly. These aggressive tumors
are associated with poor survival, and surgery remains the mainstay
of treatment. Surgical planning is increasingly informed by positron
emission tomography (PET), and tumor margin identification during
surgery is aided by near-infrared fluorescence (NIRF) imaging, yet
these investigations are confounded by probes that lack specificity
for sarcoma biomarkers. We report the development of a dual-modal
(PET/NIRF) immunoconjugate ([89Zr]Zr-DFO-anti-MT1-MMP-IRDye800CW)
that targets MT1-MMP, a matrix metalloproteinase overexpressed in
high-grade sarcomas. [89Zr]Zr-DFO-anti-MT1-MMP-IRDye800CW
was synthesized via site-specific chemoenzymatic
glycan modification, characterized, and isolated in high specific
activity and radiochemical purity. Saturation binding and immunoreactivity
assays indicated only minor perturbation of binding properties. A
novel mouse model of dedifferentiated chondrosarcoma based on intrafemoral
inoculation of HT1080 WT or KO cells (high and low MT1-MMP expression,
respectively) was used to evaluate target binding and biodistribution.
Fluorescence and Cerenkov luminescence images of [89Zr]Zr-DFO-anti-MT1-MMP-IRDye800CW
showed preferential uptake in HT1080 WT tumors. Ex vivo gamma counting revealed that uptake in MT1-MMP-positive tumors was
significantly higher than that in control groups. Taken together,
[89Zr]Zr-DFO-anti-MT1-MMP-IRDye800CW is a promising dual-modal
sarcoma imaging agent for pre-operative surgical planning and intraoperative
surgical guidance.

Abstract
We present a combined experimental and theoretical study of the fragmentation of singly and doubly N-methylated glycine (sarcosine and N,N-dimethyl glycine, respectively) induced by low-energy (keV) O6+ ions. Multicoincidence mass spectrometry techniques and quantum chemistry simulations (ab initio molecular dynamics and density functional theory) allow us to characterise different fragmentation pathways as well as the associated mechanisms. We focus on the fragmentation of doubly ionised species, for which coincidence measurements provide unambiguous information on the origin of the various charged fragments. We have found that single N-methylation leads to a larger variety of fragmentation channels than in no methylation of glycine, while double N-methylation effectively closes many of these fragmentation channels, including some of those appearing in pristine glycine. Importantly, the closure of fragmentation channels in the latter case does not imply a protective effect by the methyl group.

Abstract
The radiation protective effect of thiol compounds is unequivocal and their use is only limited by their toxic effects. We used the principle of alpha alkylation, which renders amino acids unmetabolizable, to reduce the toxicity of homocysteine. This product, alpha-methyl-homocysteine thio-lactone, was tested for toxicity and radiation protective effect along with known protectors L-cysteine, cysteamine and WR 1065 in cell culture using V79-4 Chinese hamster lung cells. The three-day growth curve assays, useful to measure overall effects on cell growth, revealed lowest toxicity for alpha-methyl-homocysteine thiolactone (GL-2). Clonogenic survival tests, used to evaluate the retention of reproductive integrity, were carried out and revealed that GL-2 had no adverse effects in this test system. Radiation protection tests showed that GL-2 exhibited protective activity against radiation induced lethality above that seen with cysteine and cysteamine, but below WR 1065. However, GL-2 showed little or no negative effects toward the cell itself, in direct contrast to WR 1065. Our findings show a potentially important tool and principle to reduce toxicity of radiation protectors with analogous structures.

Abstract
PURPOSE A variety of adjuvant treatments and cytoprotective agents have been proposed to lessen the toxicity of radiation therapy. The following study was designed to evaluate the benefit of six agents or combinations using anastomotic bursting strength as a measure of transmural radiation injury. METHODS The 40-Gy study consisted of the following. Seventy-two male Sprague-Dawley rats were divided into eight equal groups: nonradiated control, radiated untreated control, and six radiated treated groups. The radioprotective treatments included ribose-cysteine (Rib-Cys), WR-2721, glutamine, vitamin E, MgCl2/adenosine triphosphate, and RibCys/glutamine in combination. Radiated animals received 40 Gy to the abdomen. Two weeks after radiation, all animals underwent small bowel and colonic resection with primary anastomosis. Animals were sacrificed one week postoperatively, at which time anastomoses were evaluated and bursting strengths determined. The 70-Gy study consisted of the following. The same protocol was repeated for five groups of nine rats divided into nonradiated, radiated untreated, and three radiated treated groups receiving RibCys (8 mmol/kg), RibCys (20 mmol/kg), and WR-2721. All radiated animals received 70-Gy doses. RESULTS In the 40-Gy group, there were 10 radiation-related deaths and 6 anastomotic leaks among 70 rats studied. None of the differences between groups were significant. Nonradiated control group small bowel and large bowel anastomotic bursting pressures were significantly elevated compared with all radiated groups. Compared with radiated controls, there were significant improvements in small bowel bursting strength in the RibCys, WR-2721, RibCys-glutamine, and vitamin E groups and significant improvement in colonic bursting strength in MgCl2/adenosine triphosphate, WR-2721, and RibCys groups. In the 70-Gy group, all nine nonradiated control rats survived. All eight untreated radiated control rats died, four of eight WR-2721 animals died (P = 0.03), all RibCys (8 mmol/kg) animals died (P = 0.03), and three of nine treated with RibCys (20 mmol/kg) survived (P = 0.08). CONCLUSIONS WR-2721 and RibCys gave consistent protection against large and small bowel radiation injury. The lower incidence of treatment-related toxicity and potentially equal or greater radioprotective effects may make RibCys more clinically useful than WR-2721.
