Amphiphilic random copolymers bearing hydrophilic poly(ethylene glycol) (PEG) and hydrophobic alkyl pendants showed dynamic self-sorting behavior, i.e., self-recognition, under competitive conditions in aqueous media. The self-sorting universally takes place not only in water but also in hydrogels and on the material surfaces, according to encoded information originating from the primary structure of composition and pendants. Binary blends of the copolymers with different composition and/or alkyl pendants readily induced com-position and/or alkyl pendant-dependent self-sorting to simultaneously provide discrete and size-controlled micelles with hydrophobic cores...

Gram-positive bacteria signify a surface organelle that decorates the cell surfaces using Sortase enzymes. The mechanism of SrtC lings to the formation of amide or peptide bonds between cell surface proteins that sorting signal to strategically positioned amino groups. Sorting signals linked to peptidoglycan function as the principal architects of cell wall and facilitate each microbe to effectively interact with its host environment. These enzymes play a fundamental role in microbial physiology and interestingly, sequence analysis on Gram-positive bacteria implies that approximately 60% of sortases are categorized into six families, and from that SrtA and SrtC are widely investigated in various literatures...

Extensive sample preparation procedures are required to analyze natural organic matter (NOM) in soil and sediment samples due to the mineral matrix. The preparation procedure not only requires a large amount of sample (typically more than 50 mg) but also incomplete extraction of the organic can be done. In this study, 2-5 μg solid NOM or 500 μg unprocessed soil samples were fixed on a metal plate using double adhesive tape and analyzed directly using laser desorption ionization (LDI) and ultrahigh resolution mass spectrometry (UHR-MS)...

CD44 is a universally and abundantly expressed single-pass type I protein that spans the cytoplasmic membrane and is considered the principal receptor for hyaluronan in the extracellular matrix. CD44 exerts a multitude of biological functions, especially in cell adhesion and migration, and its deregulation has several pathological implications, including a putative role in cancer cell dissemination. Here we report the NMR chemical shift assignment of the recombinant intrinsically disordered CD44 cytoplasmic region (669-742)...

Vaccination remains the most effective and essential prophylactic tool against infectious diseases. Enormous efforts have been made to develop effective vaccines against malaria but successes remain so far limited. Novel adjuvants may offer a significant advantage in the development of malaria vaccines, in particular if combined with inherently immunogenic platforms, such as virus-like particles (VLP). Dioleoyl phosphatidylserine (DOPS), which is expressed on the outer surface of apoptotic cells, represents a novel adjuvant candidate that may confer significant advantage over existing adjuvants, such as alum...
