Dual- Energy CT (DECT) Pulmonary Angiography in Acute Pulmonary Thromboembolism (PTE): Causes, Semiology and Potential Diagnostic Pitfalls
ObjectivesThe dual-energy computed tomographic (DECT) technique allows the differentiation of materials with large atomic numbers such as iodine. The basic principle of dual-energy CT is material decomposition based on attenuation differences at different energy levels. The parameters for iodine extraction are a minimum value of – 960 HU, and a maximum of –600 HU. Lung parenchyma with normal perfusion in this attenuation range is presented in orange, and an area of decreased perfusion is visualized as an iodine defect area.
A New Bi-Functional Derivative of Polyethylene Glycol as Molecular Carrier for Eugenol and Ibuprofen
Eugenol (EU) and ibuprofene (IBU) were covalently bound to a bi-functionalized PEG, used as molecular carrier of drugs and the release kinetics of the two bioactive molecules was studied in vitro in buffer solution at pH 7.4, in simulated gastric fluid and in mouse plasma.
Identification of Designer Drugs using Gas Chromatography High-Resolution Mass Spectrometry and a Soft-Ionization Source
Gas chromatography-mass spectrometry (GC-MS) with electron ionization (EI) or chemical ionization (in positive or negative mode) plays an important role in the forensic analysis of designer drugs.
