Elemental sulfur cathodes for lithium/sulfur cells are still in the stage of intensive research due to their unsatisfactory capacity retention and cyclability. The undesired capacity degradation upon cycling originates from gradual diffusion of lithium polysulfides out of the cathode region.

Apolipoprotein C-III (apoC-III) regulates triglyceride (TG) metabolism. In plasma, apoC-III exists in non-sialylated (apoC-III0a without glycosylation and apoC-III0b with glycosylation), monosialylated (apoC-III1) or disialylated (apoC-III2) proteoforms. Our aim was to clarify the relationship between apoC-III sialylation proteoforms with fasting plasma

Bioisosteric replacement of acylureido moiety in 6-acylureido-3-pyrrolylmethylidene-2-oxoindoline derivatives resulted in a series of malonamido derivatives with indolin-2-one scaffold (11-14). Further conformational restrictions of the malonamido moiety led to 2-oxo-1,2-dihydropyridine (21-25) or a 4-oxo-1,4-dihydropyridine derivatives (31-36). 4-Oxo-1,4-dihydropyridine derivatives were more potent
