1. 26. Antimicrobial peptides and virulence factors in meningococcal colonisation and disease

   Författare :Miriam Geörg; Ann-Beth Jonsson; Ole E. Sørensen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; antimicrobial peptide; LL-37; cell-penetrating peptide; resistance; polynucleotide phosphorylase; molekylär biovetenskap; Molecular Bioscience;

   Sammanfattning : The Gram-negative bacterium Neisseria meningitidis is a transient commensal of the human nasopharynx, but occasionally causes life-threatening disease. During colonisation of its niche, N. meningitidis has to overcome innate immune defences, including the expression of antimicrobial peptides (AMPs). LÄS MER

3. 27. Biological and Biophysical Studies on Ruthenium Complexes

   Författare :Anna Mårtensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metal susceptibility; DNA; antimicrobial; circular dichroism; ruthenium complex; linear dichroism; isothermal titration calorimetry; intercalation;

   Sammanfattning : Small molecules that interact with DNA through intercalation are attractive candidates for treatments against cancer and microbial infections. Octahedral ruthenium(II) polypyridyl complexes, being substitution-inert, readily synthesized and coordinately saturated, has the potential of being developed in to a new family of drugs. LÄS MER

4. 28. Mechanisms and Biological Costs of Bacterial Resistance to Antimicrobial Peptides

   Författare :Hava Lofton Tomenius; Dan I Andersson; Ørjan Samuelsen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; antibiotic resistance; fitness cost; Salmonella Typhimurium; Staphylococcus aureus; bile; serum; pH response; growth rate; mice; phoP; pmrB; waaY; LPS; LL-37; defensins; membrane potential; Mikrobiologi; Microbiology;

   Sammanfattning : The global increasing problem of antibiotic resistance necessarily drives the pursuit and discovery of new antimicrobial agents. Antimicrobial peptides (AMPs) initially seemed like promising new drug candidates. Already members of the innate immune system, it was assumed that they would be bioactive and non-toxic. LÄS MER

5. 29. Antibacterial surface coatings for biomedical applications

   Författare :Saba Atefyekta; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antimicrobial surfaces; mesoporous titania; elastin-like polypeptide; antimicrobial peptide; antibiotic delivery;

   Sammanfattning : Over the past decades there has been a significant increase in the diversity and function of biomaterials. Today, medical practices utilize a large number of biomaterials in the form of medical devices and implants. However, one major obstacle that limits the efficiency of biomaterials is their susceptibility to develop infection. LÄS MER

7. 30. Antimicrobial activity of human seminal plasma and seminal plasma proteins

   Författare :Anneli Edström; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; semenogelin; antibacterial peptides; antifungal peptides; seminal plasma; antimicrobial peptides; vaginal pH; beta-microseminoprotein; peptides;

   Sammanfattning : Seminal plasma is semen without the spermatozoa. Human seminal plasma is a complex mixture of secretions from the sex accessory glands, mainly the seminal vesicles and the prostate. Seminal plasma has high protein content and it also contains ions, sugars and low molecular weight components. LÄS MER
