    Abstract : Viruses are obligate intracellular parasites, unable to replicate without exploiting machinery andmaterials from host cells. Pandemics of viral diseases have had large impacts on human socieities and are continued threats to global health. READ MORE

  2. 2. Some New Methods in Sialic Acid Chemistry

    Author : Teddy Ercegovic; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thioglycoside promoter; ganglioside; Tumor-associated antigen; lactam; lactone; sialic acid; N-acetylneuraminic acid; Neu5Ac; sialyl donor; auxiliary group; 3- S -phenylthio; bis-sialic acid lactam; 3- S -phenylseleno; silver trifluoromethanesulfonate; iodine monochloride; Organic chemistry; Organisk kemi;

    Abstract : Gangliosides (G) are sialic acid-containing cell surface glycosphingolipids capable of forming lactones, i.e. inner esters. Some gangliosides are tumor-associated antigens, and they may serve as immunogens in their lactone form, where the latter is comparatively more abundant on the surface of malignant cells. READ MORE

    Abstract : Human adenoviruses (HAdVs) are common human pathogens, causing gastrointestinal, ocular, and respiratory infections on a regular basis. Epidemic keratoconjunctivitis (EKC) is a severe ocular infection for which no approved antivirals are available. READ MORE

  5. 5. Glycan-based interactions of Streptococcus pneumoniae and the host

    Author : Karina Hentrich; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Streptococcus pneumoniae is commonly found as an asymptomatic colonizer of the nasopharynx of children, but it can also translocate to normally sterile body sites and cause severe diseases, like pneumonia, septicemia or meningitis. Pneumococci spread via aerosols. READ MORE
