The pentasaccharide glycoside corresponding to galactosylgloboside (SSEA-3), β-d-Gal p-(1 → 3)-β-d-Gal pNAc-(1 → 3)-α-d-Gal p-(1 → 4)-β-d-Gal p-(1 → 4)-β-d-Glc p-1-OCH2CH2Si-(CH3)3 (4), was synthesized via glycosylation (87%) of 2-(trimethylsilyl)ethyl 2,3,6-tri-O-benzyl-4-O-[2,3,6-tri-O-benzyl-4-O-(2,4,6-tri-O-benzyl-α-d-galactopyranosyl)-β-d- galactopyranosyl]-β-d-glucopyranoside (2) with the gl

The 1H and 13C NMR parameters, i.e., chemical shifts and coupling constants, for the pentasaccharide of the Forssman antigen and overlapping di-, tri-, and tetra-saccharide sequences thereof have been measured and assigned completely using 1D and 2D techniques, and the oligosaccharide structures have thereby been confirmed. Nuclear Overhauser effect (NOE) experiments have been carried out at three

Radical deoxygenation of methyl 3,6-di-O-benzoyl-2-deoxy-4-O-imidazol-1-yl-thiocarbonyloxy-2-phtha limido-beta-D - glucopyranoside 5 gave methyl 3,6-di-O-benzoyl-2,4-dideoxy-2-phthalimido-beta-D-glucopyranoside 6, which was converted into the corresponding methyl thioglycoside donor 9. Methylsulfenyl trifluoromethane-sulfonate-promoted glycosylation of 2-(trimethylsilyl)ethyl 2,3,6-tri-O-benzyl-4-

This article presents the investigation of two linen shirts which form part of the funerary dress of Bishop Peder Pedersen Winstrup (1605–1679), buried 1680 in Lund Cathedral, southern Sweden. When the grave was opened in 2013, it was discovered that the body had been naturally mummified, and that the funerary dress, including the linen, was well-preserved. Extant Early Modern linen garments are r

The sugar binding specificities of two groups of Streptococcus suis, a pig pathogen that causes meningitis also in man, were determined. Both the group represented by a recently characterized strain inhibitable by galactose and N-acetylgalactosamine (type PN) and the group inhibitable by galactose (type PO) were found by hemagglutination and solid-phase binding inhibition experiments to recognize

The 2-(trimethylsilyl)ethyl (TMSEt) β-glycosides of the Forssman pentasaccharide [α-d-GalNAc-(1 → 3)-β-d-GalNAc-(1 → 3)-α-d-Gal-(1 → 4)-β-d-Gal-(1 → 4)-d-Glc] and the terminal tetrasaccharide, as well as the methyl glycosides 1 and 2 of the terminal di- and tri-saccharides, were synthesised by silver trifluoromethanesulfonate-promoted α-glycosylation of suitably protected mono-, di-, tri-, and tet

The 2-(trimethylsilyl)ethyl (TMSEt) β-glycosides of globotetraose [β-d-GalNAc-(1 → 3)-α-d-Gal-(1 → 4)-β-d-Gal-(1 → 4)-d-Glc] and the terminal trisaccharide, as well as the methyl α-glycoside 1 of the terminal disaccharide, were synthesised by silver trifluoromethanesulfonate-promoted β-glycosylation of suitably protected galactoside, galabioside, and globotrioside alcohols with 3,4,6-tri-O-acetyl-

This article brings agency to discussions on financialization and financial education in Sweden by zooming in on two barely examined actors and arenas: civil society and public schools, respectively. The civil society organization Aktiespararna (Swedish Shareholders’ Association, founded in 1966) attempted to access and impact school education starting with its launch of youthefforts in the 1980s.

2011 öppnade ukrainska regeringen upp för turister att besöka staden Prypjat och området runt kärnkraftverket Tjernobyl. Vad kan man se i dessa tusentals turistbilder på en Sovjetisk utopi som övergavs efter kärnkraftskatastrofen? Fannie Frederikke Baden, doktorand i konsthistoria och visuella studier vid Institutionen för kulturvetenskaper, berättar. Inspelat den 8 april 2022 i Lux aula i Lund. A

A fundamental difference between ordinary and leisure time is for many the ability to indulge in extra-ordinary activities of both body and mind. Rooted in antiquity, the renaissance villas were often used as spaces for indulgence of artistic endeavors, be it philosophical discussions, poetry-writing or lavish parties. Of indulgence, Aristoteles wrote: ‘The self-indulgent man craves for all pleasa

The current plastic system is unsustainable and needs to change. Plastics are mainly produced from fossil feedstock, contributing to greenhouse gas emissions, and low rate of post-consumer recycling results in pollution on land and in oceans with high ecological impact, and huge loss of valuable material. There is an urgent need to find solutions for shifting the raw material base to renewable res

Spectral imaging and lidar methods for the characterization of vegetation are vital for understanding plants and, in turn, food security, biodiversity, and vegetation health in a changing climate. While novel hyperspectral imaging, canopy lidar,and solar-induced fluorescence provide details on species, state, structure, and plant physiology, such data come from different instruments. Thus, post-pr
