Respiration is a process of gas exchange in the lungs, but also a cellular process of food metabolism for energy production. The health of the respiratory system is therefore tightly connected with the appropriate diet. Food not only provides energy for the body, but many food ingredients exert various biological eff ects which are important for he...

Bone morphogenetic protein 6 (BMP6) is a member of TGF-β superfamily with a high potential to induce new bone and cartilage. Here we demonstrate that BMP6 compared to the BMP7 paralog has unique biological properties. Previously, we showed that BMP6 is more active at lower amounts then BMP7 because of increased resistance to noggin due to lysine in...

Structural optimisation of the 1,2,3-triazole-linked 5-amidinobenzimidazole class encouraged by the promising anti-bacterial activity and anti-trypanosomal potency of previously synthesized amidinobenzimidazole derivatives connected to 1-aryl-substituted 1,2,3-triazole through phenoxymethylene linkers.
Project
In the project we propose to study 40 newly diagnosed IBD patients and 20 non-IBD subjects and assess their gut microbiota composition, blood inflammatory markers and hormones, and correlate them with their nutritional status. After enrolment subjects will complete specially designed questionnaires regarding quality of life and dietary habits. Their blood and stool samples, in addition to intestine tissue biopsies will be collected and analysed for biomarkers and gut microbiota present. It is expected that upon complete statistical and bioinformatical data analyses, correlation of investigated factors with the disease status will be obtained for the studied group of patients. This pilot-clinical research study dealing with the cutting-edge topics and using state-of–the art sensitive methodologies may provide insight in the interrelationship of investigated parameters and contribute to improved patient stratification and introduce better guiding principles when deciding on the therapy and nutritional intervention in IBD patients. The project is funded by the Croatian Science Fundation (period 2014-2018)
