What is an "early palliative care" intervention? A scoping review of controlled studies in oncology.

Introduction: Early palliative care (EPC) has been advocated to improve cancer patients' health. However, EPC differs with regard to its elements and target groups. It is not known which parts of EPC contribute to effectiveness for which patient group.

Discovery of Imidazoquinolines as a Novel Class of Potent, Selective, and in Vivo Efficacious Cancer Osaka Thyroid (COT) Kinase Inhibitors.

Cancer Osaka thyroid (COT) kinase is an important regulator of pro-inflammatory cytokines in macrophages. Thus, pharmacologic inhibition of COT should be a valid approach to therapeutically intervene in the pathogenesis of macrophage-driven inflammatory diseases such as rheumatoid arthritis. We report the discovery and chemical optimization of a novel series of COT kinase inhibitors, with unprecedented nanomolar potency for the inhibition of TNFα.

An MS/MS library on an ion-trap instrument for efficient dereplication of natural products. Different fragmentation patterns for [M + H]+ and [M + Na]+ ions.

The structural novelty of lead compounds is very important in the agrochemical and pharmaceutical industries, and as such, natural products can be an important source. Taking into account that the isolation of lead compounds is very time-consuming, the efficient and safe identification of compounds in microorganism and plant extracts isolated previously is essential. A suitable procedure for this task based on an HPLC system interfaced with an electrospray (ESI) source and a Thermo Finnigan LCQ deca XP plus ion-trap mass spectrometer was developed, and an extensive MS/MS spectral library of characterized natural products was built up.

Stability measurements of antisense oligonucleotides by capillary gel electrophoresis.

The approach of using antisense oligonucleotides as potential drugs is based on hybridization of a short chemically-modified oligonucleotide with complementary cellular DNA or RNA sequences. A critical question is the stability of chemically modified antisense oligonucleotides in cellular environments. In a model system, resistance against various nucleases was evaluated by capillary gel electrophoresis (CGE).

Modification of a tunable UV-visible capillary electrophoresis detector for simultaneous absorbance and fluorescence detection: profiling of body fluids for drugs and endogenous compounds.

Using fused-silica optical fibres for fluorescence light collection and bandpass filters for selection of emission wavelengths, a capillary electrophoresis detection cell of a conventional, tunable UV-Vis absorbance detector was adapted for simultaneous fluorescence (at selected emission wavelength) and absorbance (at selected excitation wavelength) detection. Detector performance is demonstrated with the monitoring of underivatized fluorescent compounds in body fluids by micellar electrokinetic capillary chromatography with direct sample injection. Compared with UV absorption detection, fluorescence detection is shown to provide increased selectivity and for selected compounds also up to tenfold higher sensitivity.
