The present paper describes matrix-free laser desorption/ionisation mass spectrometric imaging (LDI-MSI) of highly localized UV-absorbing secondary metabolites in plant tissues at single-cell resolution. The scope and limitations of the method are discussed with regard to plants of the genus Hypericum. Naphthodianthrones such as hypericin and(More)
A 23-year-old man with follicular thyroid carcinoma and cervical lymph node metastases showed a clear I focus on the skull after radioiodine therapy; therefore, an osseous metastasis was suspected. I and MRI fusion suggested the I focus to be adjacent to an epicranial suture from an early childhood trepanation for epidural hematoma. Radio-guided surgery(More)
Analgesic drugs, physiotherapy and corticosteroids are concurrently used in the conservative treatment of lumbar pain. In 100 patients a double-blind study with dexamethasonephosphate versus placebo was performed. Lumbar pain and no findings with myelography were the basic requirements for inclusion into the study. There was no significant difference(More)
A simple sodium chloride (NaCl) based (68)Ga eluate concentration and labeling method that enables rapid, high-efficiency labeling of DOTA conjugated peptides in high radiochemical purity is described. The method utilizes relatively few reagents and comprises minimal procedural steps. It is particularly well-suited for routine automated synthesis of(More)
Metal complexes possess unique tunable properties, such as radioactivity, cytotoxicity or photophysical features, enabling them to act as diagnostic tracers or therapeutic agents. In applying them in biological systems, it is often necessary to enhance their solubility and biocompatibility. To achieve such goals, like the targeting of binding domains,(More)
Clinical and neuropathological findings in monozygous twin sisters are reported. Twin I died at age 5 months from a cerebellar medulloblastoma, whereas her sister died at age 16 months from a pineoblastoma. The tumors are considered similar referring to histogenesis, structural peculiarities and growth. Therefore, the twins are seen as concordant for the(More)

Poly(2-oxazoline)s (POxs) are a versatile class of biocompatible polymers, which have been investigated as poly(ethylene glycol) (PEG) alternatives. In recent years, POxs have drawn significant attention as coatings for antifouling applications. In this tutorial review different approaches to immobilize POxs on surfaces as well as properties and(More)
