BACKGROUND In bacteria with truncated lipopolysaccharide structures, i.e., lacking the O-antigen polysaccharide part, core structures are exposed to the immune system upon infection and thus their use as carbohydrate surface antigens in glycoconjugate vaccines can be considered and investigated. One such suggested structure from Haemophilus influenzae LPS is the phosphorylated pentasaccharide 6...

Starting from allyl 2-O-acetyl-3-O-benzyl-α-l-rhamnopyranoside (3), allyl (2,3,4,6-tetra-O-benzoyl-β-d-galactopyranosyl)-(1→4)-2-O-acetyl-3-O-benzyl-α-l-rhamnopyranoside (5) was synthesized under Helferich conditions. Module 5 was converted to 2,3,4,6-tetra-O-benzoyl-β-d-galactopyranosyl-(1→4)-2-O-acetyl-3-O-benzyl-α-l-rhamnopyranosyl bromide (8) which was then coupled with methyl (allyl 2,3-di...

TEMPO-Oxidized cellulose nanofibrils (toCNF), in the form of highly entangled network such as membrane or cryogels, have proven to be interest for various applications, including drug release purification by pollutant adsorption. β-Cyclodextrins (β-CDs) ability inclusion complexes with large amount hydrophobic molecules, and are considered a promising way bring new functionalities these materia...

Sansevieria is a genus consisting of about 60 species natively distributed in tropical and subtropical areas. Many are used for ornamental purposes or traditional medicine to treat human diseases. trifasciata ‘Laurentii,’ commonly known as snake plant, an evergreen perennial plant medicine. The phytochemical investigation the roots S. ‘Laurentii’ resulted isolation structural characterization t...

Givotia rottleriformis has been used in the indigenous systems of medicine for the treatment of inflammatory diseases like rheumatism and psoriasis. In order to evaluate this information, antipsoriatic activity of three flavonoids isolated from the ethanol extract of the bark of Givotia rottleriformis were investigated using in-vitro and in-vivo model, namely Rutin (I), Luteolin-7-O-β-D-Glucuro...

This paper presents the results of analysis acetone, chloroform and diethyl ether extracts three types wormwood: Artemisia absinthium L., armeniaca Lam. latifolia Ledeb., performed by gas chromatography–mass spectroscopy. β-myrcene was found in A. from biologically active substances; latifolia, pinene; 3,6-difluoro-4-[1-hydroxy-2-(methiamino)ethyl]benzene-1,2-diol, ethyl palmitate, β-phellandre...

Numerous genetic polymorphisms and clinical laboratory parameters are associated with ischemic stroke (IS). However, the results of such studies have frequently been inconsistent. The aim present study was to evaluate associations between that influence risk IS in a Chinese Han population. Clinical were measured by an automatic biochemical analyzer. Genotype allele frequencies angiotensin‑conve...
