13 N-NH 3 PET/CT in oncological disease

Abstract13N-Ammonia (13N-NH3) is widely used positron emission tomography/computed tomography (PET/CT) radiotracer for the measurement of myocardial blood perfusion; the possible role of13N-NH3 PET or PET/CT in oncological disease is not yet clear. Aim of this review is to evaluate the diagnostic performances of13N-NH3 PET in this field. A comprehensive computer literature search of the PubMed/MEDLINE, Scopus, and Embase databases was conducted including articles up to June 2019. Eighteen articles were finally included in the review. From the analyses of the selected studies, the following main findings could be drawn: (1)13N-NH3 PET is useful in discriminating between gliomas and non-neoplastic brain lesions, and among gliomas between high-grade and low-grade gliomas; (2)13N-NH3 PET have better diagnostic performance than18F-FDG in studying gliomas; (3) a combination of13N-NH3 PET and18F-FDG PET may be useful to differentiate between several cerebral lesions (gliomas, cerebral lymphoma, meningioma); (4) only preliminary results about the positive impact in liver and prostate cancer.

ConclusionsTattooing of axillary LNs is safe and easily performed. Tattooing was helpful in identifying the marked LN in the majority of cases. This technique helps to ensure that metastatic LNs are identified and removed at surgery after NAT.

Ott Research Institute of Obstetrics, Gynecology and Reproductology, Saint Petersburg, Russia 2Department of Genetics and Biotechnology, Saint Petersburg State University, Saint Petersburg, Russia In the present review, we focus on the phenomenon of chromothripsis, a new type of complex chromosomal rearrangements. We discuss the challenges of chromothripsis detection and its distinction from other chromoanagenesis events. Along with already known causes and mechanisms, we introdu...

Markus Hartl* and Rainer Schneider Center of Molecular Biosciences (CMBI), Institute of Biochemistry, University of Innsbruck, Innsbruck, Austria The neuronal proteins GAP43 (neuromodulin), MARCKS, and BASP1 are highly expressed in the growth cones of nerve cells where they are involved in signal transmission and cytoskeleton organization. Although their primary structures are unrelated, these signaling proteins share several structural properties like fatty acid modification, and the presence of cationic effector domains. GAP43, MARCKS, and BASP1 bind to cell membrane phospholipids, a process reversibly regulate...

Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroinfla...
