Detection of Fusarium Species in Clinical Specimens by Probe-Based Real-Time PCR
2019
The mold Fusarium is a ubiquitous fungus causing plant, animal and human infections. In humans, Fusarium spp. are the major cause of eye infections in patients wearing contact lenses or after local trauma. Systemic infections by Fusarium spp. mainly occur in immunosuppressed patients and can disseminate throughout the human body. Due to high levels of resistance to antifungals a fast identification of the causative agent is an urgent need. By using a probe-based real-time PCR assay specific for the genus Fusarium we analysed several different clinical specimens detecting Fusarium spp. commonly found in clinical samples in Germany. Also, a large collection of lung fluid samples of haematolog…
Personalized cancer medicine: from molecular diagnostics to targeted therapy with natural products.
2010
Personalized cancer medicine aims to develop individualized treatment options adapted to factors relevant for the prognosis of each patient. Molecular biomarkers are required to predict the likelihood of an individual tumor's responsiveness or of toxicity in normal organs and to advise optimized treatments with improved efficacy at reduced side effects for each cancer patient. In the present review, we present a concept, which takes advantage of methods of molecular diagnostics to identify predictive markers at the DNA, mRNA, and protein levels. Markers with prognostic value concerning treatment response and patient survival can then be used as targets to develop optimized drugs. We focus o…
Therapeutic and diagnostic applications of nanoparticles.
2011
Nanoparticles are sphere-like biocompatible materials made of inert silica, metal or crystals of a few nanometers in size. They are emerging as a novel class of therapeutics for cancer treatment. Being more selective and specific toward their targets, nanoparticles have the ability to enhance the anticancer effects and to simultaneously reduce systemic toxicity compared with conventional therapeutics. Furthermore, they offer the potential to overcome drug resistance leading to higher intracellular drug accumulation. Nowadays, nanotechnologies are applied to molecular diagnostics and incorporated in cutting-edge molecular diagnostic methods, such as DNA and protein microarray biochips. Nanot…
Molecular diagnostics in gastric cancer.
2014
Despite recent advances in individualised targeted therapy, gastric cancer remains one of the most challenging diseases in gastrointestinal oncology. Modern imaging techniques using endoscopic filter devices and in vivo molecular imaging are designed to enable early detection of the cancer and surveillance of patients at risk. Molecular characterisation of the tumour itself as well as of the surrounding inflammatory environment is more sophisticated in the view of tailored therapies and individual prognostic assessment. The broad application of high throughput techniques for the description of genome wide patterns of structural (copy number aberrations, single nucleotide polymorphisms, meth…
High-affinity and selective detection of pyrophosphate in water by a resorcinarene salt receptor
2017
N-Alkyl ammonium resorcinarenes selectively bind pyrophosphate in pure water with an exceptionally high binding constant of up to 1.60 × 107 M–1, three orders of magnitude higher than ATP.
