2. 16. Importance of bacterial hydrogen sulfide in the pathogenesis of periodontal diseases

   Author : Amina Basic; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hydrogen sulfide; Periodontitis; Gingivitis; IL-1β; IL-18; NLRP3 inflammasome; Oral microbiota; Fusobacterium spp.; Bismuth test; L-cysteine;

   Abstract : Hydrogen sulfide (H2S) is one of many end-products of the proteolytic activities in the subgingival microbiota in patients with periodontal diseases, such as gingivitis and periodontitis. Although H2S is generally regarded as toxic, the mechanisms that underlie its production and its effects on human cells and tissues are poorly understood. READ MORE

4. 17. Role of POU/Oct transcription factors in Drosophila immunity

   Author : Widad Dantoft; Ylva Engström; Anne Uv; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antimicrobial peptides; Drosophila; host-pathogen interaction; immune gene expression; immune signaling; NF-kB; microbiota; POU Oct transcription factors; protein degradation; stress response; transcriptional regulation; Molecular Biology; molekylärbiologi;

   Abstract : In response to infection, Drosophila melanogaster relies on the ability to mount a robust and potent innate immune response, characterized by induction of cellular and humoral processes. While rapid immune induction is of utmost importance, it is equally important to restrict and repress immune gene expression, where and when it is not needed. READ MORE

5. 18. Infections Related to the Use of Medical Devices and Changes in the Oropharyngeal Flora

   Author : Hulda Thorarinsdottir; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thrombosis; critical illness; biofilm; intratracheal intubation; ventilator-associated pneumonia; ; central venous catheters; catheter-related infections; proton pump inhibitors; oropharynx; MICROBIOTA; foreign-body reaction; hemolysis; inflammation;

   Abstract : Background: Humans exist in mutualistic balance with a large range of microbiota. Illness and hospitalization can disturb this balance and contribute to hospital-acquired infections (HAIs), which occur most often in critically ill patients. READ MORE

6. 19. Effects of feeding term infants low energy low protein formula supplemented with bovine milk fat globule membranes

   Author : Niklas Timby; Magnus Domellöf; Olle Hernell; Bo Lönnerdal; Ekhard Ziegler; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; infant formula; milk fat globule membranes; energy; protein; growth; cognition; parental control; infection; cholesterol; oral microbiota; Pediatrics; pediatrik;

   Abstract : Background Observational studies have shown that early nutrition influences short- and long-term health of infants. Formula-fed infants have higher protein and energy intakes and lower intakes of several biologically active components present in human milk. Some of these are present in the milk fat globule membrane (MFGM). READ MORE

7. 20. Microbiota of the alimentary tract of children - implications for allergy and inflammatory bowel disease

   Author : Fei Sjöberg; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gut flora; child; oral flora; allergy; duodenum; inflammatory bowel disease; culture; T-RFLP; pyrosequencing;

   Abstract : Allergy, which is the most common chronic disease in Swedish children and adolescents, is associated with a high standard of living and Western lifestyle. According to the hygiene hypothesis, allergy is due to inadequate stimulation of the immune system by microbes during early childhood, leading to failed maturation of the immune system. READ MORE
