  1. 6. Molecular diagnosis of drug resistance in Plasmodium falciparum and virulence factors in Entamoeba histolytica

    Författare :Sherwan Zindrou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Plasmodium falciparum; dhfr gene; pyrimethamine; cycloguanil; mutations; Polymerase chain reaction; Entamoeba histolytica; hemolysins; hemolysis; virulence factors.;

    Sammanfattning : Four species of the protozoan parasite genus Plasmodium are known to infect man. Plasmodium falciparum, the most virulent species is increasingly associated with resistance to antimalarial drugs. LÄS MER

  3. 7. Flagellates in the marine microbial food web : the ecology of a mixotrophic nanoflagellate, Ochromonas sp

    Författare :Agneta Andersson-Nordström; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbial food web; flagellates; Ochromonas sp.; mixotrophy; size- selective grazing; remineralisation; excretion of DFAA;

    Sammanfattning : Nanoflagellates were found to be abundant in a coastal area of the northern Bothnian Sea. The maximum concentration of nanoflagellates, approximately 8000 cells ml-1, was observed in July, coinciding with a decrease in the abundance of cyanobacteria. LÄS MER

  4. 8. Cryo-EM and Computational Biology of Macromolecular Complexes

    Författare :Andrew Emmerich; Suparna Sanyal; Erik Lindahl; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : The ribosome is a large, ancient multicomponent macromolecular complex which is highly amenable to study by cryogenic electron microscopy (cryo-EM) and computation biology methods. This thesis delves into the structure of both prokaryotic and eukaryotic ribosomes in the context of determining a solution to emerging antimicrobial resistance. LÄS MER

  5. 9. Biochemical and structural studies of proteins supporting the genome replication of enteroviruses and Giardia intestinalis

    Författare :Kasturika Shankar; Lars-Anders Carlson; Daniel Hurdiss; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Structural Biology; Membrane reconstitution; Infectious diseases; Virus; Protozoa; Infectious Diseases; infektionssjukdomar; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : The Enterovirus genus of the Picornaviridae family includes non-enveloped, positive-sense single-stranded RNA (ssRNA) viruses. This genus of viruses causes many diseases such as poliomyelitis by poliovirus (PV), cardiomyopathy by coxsackievirus B3 (CVB3), common cold by rhinoviruses (RVs) and meningitis by Enterovirus 71 (EV 71).

  7. 10. Characterization of secreted Giardia intestinalis cysteine proteases

    Författare :Jingyi Liu; Staffan G Svärd; Lars Hellman; Andre Buret; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Giardia intestinalis; ESPs; CPs; apical junction; chemokines; phage display; immunoglobulins; defensins; mucin.; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Giardia intestinalis, the causative agent of the diarrheal disease giardiasis, is a protozoan parasite that colonizes the upper small intestine of mammals, including humans. It can be divided into eight genotypes or assemblages (A through H) and only assemblage A and B are infective to humans. LÄS MER
