Czy umiemy wiarygodnie mierzyć stężenie klinicznie ważnych metabolitów witaminy D? Problemy i ich konsekwencje

Increased interest in vitamin D measurements in clinical studies has contributed to the development in recent years of several new immunochemical assays (manual and for automatic analyzers). New methods, including HPLC (high performance liquid chromatography), and LC-MS/MS (liquid chromatography coupled with tandem mass spectrometry) have also been introduced into routine diagnostic laboratorie...

Temperature dependence of I-V characteristics of C60 molecule

Making use of a generalized Green’s function technique and Landauer formalism, the temperature depended current-voltage (I-V) characteristics of C60 molecule, sandwiched between two metallic electrodes are numerically investigated. In addition, the influence of the electron-phonon coupling strength on the electronic properties of the molecule is studied. The I-V characteristics of the molecule ...
