  1. 31. Structural and Functional Studies of Chagasin, a Parasite Protease Inhibitor

    Författare :Anna Ljunggren; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The cysteine proteases are enzymes found in every kingdom of life. Clan CA is the largest of the cysteine protease clans, with members all displaying a Cys/His/Asn(Asp) catalytic triad responsible for hydrolysing the peptide bond within the substrate. LÄS MER

  3. 32. Gene Regulation and Epigenetic Mechanisms in the Parasite Trypanosoma cruzi

    Författare :Patricia Respuela; Lena Åslund; George A.M. Cross; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Molecular Biology; Molekylärbiologi;

    Sammanfattning : Trypanosomes are unicellular protozoan parasites responsible for several human diseases that affect millions of people and cause thousands of casualties every year. They also represent a primitive eukaryotic model system harboring unique processes and basic regulatory mechanisms such as RNA-editing, polycistronic transcription and trans-splicing, first described in these organisms.

  4. 33. Host-parasite interaction in men with febrile urinary tract infection

    Författare :Peter Ulleryd; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; urinary tract infection; fever; male; Escherichia coli; serotype; virulence; PSA; prostate; prostatitis; TRUS; urography; cystoscopy; treatment; ciprofloxacin;

    Sammanfattning : In a retrospective study, Escherichia coli isolates from 88 men with symptomatic urinary tract infection (UTI) were analysed. A wide array of O:K:H serotypes commonly associated with acute pyelonephritis in women were identified. LÄS MER

  5. 34. Speciation - What Can be Learned from a Flycatcher Hybrid Zone?

    Författare :Chris Wiley; Anna Qvarnström; Lars Gustafsson; Roger Butlin; Uppsala universitet; []
    Nyckelord :Biology; speciation; reinforcement; fitness; postzygotic isolation; asymmetrical hybridization; hybrid zone; species recognition; mate choice; sexual selection; direct benefits; parasite resistance; delayed plumage maturation; Ficedula hypoleuca; Ficedula albicollis; flycatcher; Biologi;

    Sammanfattning : Studies of hybrid zones offer important insights into the process of speciation. Much of the knowledge to be gained is dependent on an accurate estimation of the strength of pre- and post-zygotic isolation between hybridizing taxa. My results demonstrate that hybridization can variously affect different components of fitness. LÄS MER

  7. 35. Parasite signalling and host responses in experimental and human African trypanosomiasis

    Författare :Maha Hamadien; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :TLTF; anti-TLTF antibodies; IFN-gamma; Human African trypanosomiasis; T b. brucei; ;

    Sammanfattning : African trypanosomiasis or sleeping sickness is a disease of tropical Africa caused by the unicellular-flagellated protozoan parasite, Trypanosoma brucei (T b.), which is transmitted by its insect vector, the tsetse fly. In humans, there are two forms of the disease: a chronic form in West and Central Africa, caused by T. b. LÄS MER
