Glycosylation reactions of the ethylthio, bromo and chloro derivatives of 1-deoxy-1-ethoxysulfonyl-hept-2-ulopyranose were studied applying different acceptors under different conditions. Elimination side-reactions affording exo- and endoglycals occured in all cases, however, with different proportions. Glycosyl chloride donor was applied to glycosylate a trisaccharide acceptor obtaining a new sulfonic acid mimetic of the sialyl Lewis X tetrasaccharide in high yield.

Background: Environmental pollutants, called perfluoroalkyl substances (PFAS) have been linked to adverse cardiometabolic outcomes, immune dysfunction and cancer risk, but their associations with adult cognition are unknown. Nearly everyone in the United States has detectable levels of PFAS in their blood, but our prior work found that Asian Americans have the highest exposure burden. As Asian Americans fastest growing segment of older adults, examination of relationships between serum PFAS concentrations and cognition in Asian Americans urgently needed.

Herein, we discuss the idea that fluorescent materials/molecules should logically show potential photoelectrochemistry (PEC) activity, and, in particular, the PEC of fluorescent small molecules (previously usually acting only as dye sensitizers for conventional semiconductors) is explored. After examining the PEC activities of some typical inorganic or organic fluorescent materials/molecules and by adopting methyl violet (MV) with the highest PEC activity among the examined fluorescent small molecules, a new and efficient (MV/Au nanoparticles (AuNPs))/fluorine-doped tin oxide (FTO) photoanode without conventional semiconductor(s) is prepared by layer-by-layer alternating the electrodeposition of AuNPs and the adsorption of MV. A bilirubin oxidase (BOD)/CuCoO/FTO bio-photocathode is prepared by electrodeposition, calcination and cast-coating.

SnO₂ is a widely used electron transport layer (ETL) material in perovskite solar cells (PSCs), and its design and optimization are essential for achieving efficient and stable PSCs. In this study, the in situ formation of a chain entanglement gel polymer electrolyte is reported in an aqueous phase, integrated with SnO₂ as the ETL. Based on the self-polymerization of 3-[[2-(methacryloyloxy)ethyl]dimethylammonium]propane-1-sulfonic acid (DAES) in an aqueous environment, combining the catalytic effect of LiCl (as a Lewis acid) with the salting-out effect, and the introduction of polyvinylpyrrolidone (PVP) as the other polymer chain, a chain entanglement gelled SnO (G-SnO) structure is successfully constructed with a wide range of functions.

Graft-versus-host disease (GVHD) is less common in autologous stem cell transplantation (ASCT) recipients than in allogeneic SCT recipients. However, some cases of severe GVHD, especially involving the gastrointestinal (GI) tract, have been documented. We present a patient with primary central nervous system lymphoma (PCNSL) exhibiting severe GI-GVHD after ASCT with busulfan/thiotepa conditioning.
