(Elsevier, 2022-02)A new synthesis method was developed and optimized by a full factorial design for conjugating hydroxycinnamic acids (HCA-s) to chitosan. Cinnamic acid and tert-butyldimethylsilyl protected HCA-s were converted to their corresponding acyl chlorides ... -
(Elsevier B.V., 2021-09-01)Here we describe the first synthesis of a new type of polysaccharides derived from chitosan. In these structures, the 2-amino group on the pyranose ring was quantitively replaced by an aromatic 1,2,3-triazole moiety. The 2-amino group of chitosan and ...

(MDPI AG, 2019-04-09)N,N,N-trimethyl chitosan (TMC) with 93% degree of trimethylation was synthesized. TMC and the chitosan starting material were subjected to acidic hydrolysis to produce 49 different samples with a reduced average molecular weight (Mw) ranging from 2 to ...

(American Society for Microbiology, 2019-05-08)Vaccinations with the 10-valent pneumococcal conjugated vaccine (PHiD-CV) started in Iceland in 2011. Protein D (PD) from H. influenzae, which is coded for by the hpd gene, is used as a conjugate in the vaccine and may provide protection against ...

(American Society for Microbiology, 2018-09-26)Vaccination with pneumococcal conjugate vaccines (PCVs) disrupts the pneumococcal population. Our aim was to determine the impact of the 10-valent PCV on the serotypes, genetic lineages, and antimicrobial susceptibility of pneumococci isolated from ...

(University of Iceland, School of Health Sciences, Faculty of Medcine, 2016-10-14)Streptococcus pneumoniae, pneumókokkar, sem ekki voru næmir fyrir penisillíni (PÓP) fundust fyrst á Íslandi 1988 og urðu á fjórum árum 20% allra pneumókokka stofna sem greindust hjá sjúklingum. Flestir voru þeir af hjúpgerð 6Bii/E, CC90. Árið 2011 ...

(2020)Background Penicillin non-susceptible (PNSP) and multi-resistant pneumococci have been prevalent in Iceland since early nineties, mainly causing problems in treatment of acute otitis media. The 10-valent protein conjugated pneumococcal vaccine (PHiD-CV) ...
