    Författare :Gunilla Hjerdt-Goscinski; Jan Sjölin; Monica Lundholm; Inga Odenholt; Ingrid Nilsson-Ehle; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Communicable diseases; Endotoxin; LPS; exotoxin; SpeA; penicillin-binding protein; aminoglycosides; clindamycin; β-lactam antibiotics; severe sepsis; septic shock; Infektionssjukdomar; Infectious diseases; Infektionssjukdomar;

    Sammanfattning : Toxic products, such as endotoxin from the gram-negative and exotoxin from the gram-positive bacteria, are the most important initiators of the inflammatory host response in sepsis. In addition to antibacterial treatment, numerous attempts have been made to interfere with the exaggerated proinflammatory cascade initiated by the toxins. LÄS MER

  2. 2. Invasive group A streptococcal infection : host and pathogen interactions

    Författare :Björn K G Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Group A streptococci; invasive infections; erysipelas; Streptococcal Toxic Shock Syndrome STSS ; epidemiology; M1 serotype streptococcal pyrogenic exotoxins Spe ; SpeA; toxin neutralization; opsonization;

    Sammanfattning : Invasive group A streptococcal (GAS) infections were studied in 229 patients with a clinical diagnosis of erysipelas and 151 patients with GAS bacteremia, respectively. Beta-hemolytic streptococci were identified in about a third of the erysipelas patients, mostly group A, whereas group G streptococci were identified in about half as many episodes. LÄS MER

  3. 3. On the Selection and Classification of Features for Speaker Recognition

    Författare :Guillermo Garcia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feature extraction; mutual information; estimation; phase information.; Bayes procedures; speaker recognition; discriminative modeling;

    Sammanfattning : Speaker recognition is theprocess of automatically recognizing who is spea- king based on information provided by speech signals. Speakerrecognition still has many unsolved problems; each person has aunique voice that makes him or her different from other people, andto recognize who is talking based only on the speech is not an easytask.

  4. 4. Superantigens in group A streptococcus : gene diversity and humoral immune response

    Författare :Linda Maripuu; Mari Norgren; Susan Hollingshead; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Group A streptococcus; Streptococcus pyogenes; superantigen SAg ; SAg-gene profile; M-protein; emm-genotype; biomedicinsk laboratorievetenskap; biomedical laboratory science;

    Sammanfattning : Group A streptococcus (GAS) is a strictly human pathogen that causes infections ranging from asymptomatic carriage to the highly lethal streptococcal toxic shock syndrome (STSS). GAS are classified according to the sequence of the variable 5’ end of the emm-gene that encodes the surface associated M-protein. LÄS MER

  5. 5. Pathogenesis and immunotherapy of streptococcal septicemia and shock

    Författare :Nahla Ihendyane; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Streptococcus; Cytokines; Superantigens; Sepsis; Inflammation; IVIG;

    Sammanfattning : Streptococei have been recognized as important causes of severe sepsis. Increased frequencies of streptococcal toxic shock syndrome caused by group A streptococcus (GAS) have been noted worldwide during the last 15 years. LÄS MER
