Endocarditis and molecular imaging [PDF]
Clinically managing acute endocarditis, an infection of the heart valves with a mortality rate of up to 47%, remains highly challenging and frequently unsuccessful (1, 2). The most common pathogen behind acute endocarditis is Staphylococcus aureus, followed by Streptococcus species (2, 3). Unmet clinical needs in treating acute endocarditis include: (i)

More and more studies have shown that long noncoding RNAs (lncRNAs) play essential roles in malignant tumors. The lncRNA MEG3 serves as a crucial molecule in breast cancer development, but the specific molecular mechanism needs to be further explored. We

Imaging correlates of molecular signatures in oligodendrogliomas. [PDF]
Molecular subsets of oligodendroglioma behave in biologically distinct ways. Their locations in the brain, rates of growth, and responses to therapy differ with their genotypes. Retrospectively, we inquired whether allelic loss of chromosomal arms 1p and

Molecular Imaging of Hypoxia [PDF]
Hypoxia, a condition of insufficient O2 to support metabolism, occurs when the vascular supply is interrupted, as in stroke or myocardial infarction, or when a tumor outgrows its vascular supply. When otherwise healthy tissues lose their O2 supply acutely, the cells usually die, whereas when cells gradually become hypoxic, they adapt by up-regulating ...

Molecular Ultrasound Imaging [PDF]
Contrast-enhanced ultrasound (CEUS) imaging is a valuable tool for preclinical and clinical diagnostics. The most frequently used ultrasound contrast agents are microbubbles. Besides them, novel nano-sized materials are under investigation, which are briefly discussed in this chapter.

An alternative methodology for the determination of the radiochemical purity of 11C-methionine
Background [11C]Methionine ([11C]MET) acts as an oncological radiopharmaceutical for measuring increased protein synthesis in brain tumours while having low uptake in normal brain an.

Molecular Imaging of the Breast
Contrast-enhanced magnetic resonance imaging (MRI), MR spectroscopy, and nuclear medicine sestamibi imaging using technetium-99m methoxyisobutyl isonitrile or positron emission tomography (PET) techniques provide information beyond that of structural imaging by displaying tumor neoangiogenesis, tumor metabolites, increased numbers of tumor cellular ...

Advances in Analysis of Biodistribution of Exosomes by Molecular Imaging
Exosomes are nano-sized membranous vesicles produced by nearly all types of cells. Since exosome-like vesicles are produced in an evolutionarily conserved manner for information and function transfer from the originating cells to recipient cells, an ...
