To analyse the association between isoflavone intake and ulcerative colitis motility symptoms in individuals in remission. METHODSCross-sectional study was conducted in a group of ulcerative colitis remission individuals, in sub-groups characterised by various intestinal motility and functioning characteristics (abdominal pain, flatulence, constipations, tenesmus). Total of 56 individuals with ulcerative colitis in remission (19 males and 37 females) were recruited for the study. Assessment of diet was based on self-reported data from each patient’s dietary records taken over a period of three typical, random days (2 weekdays and 1 d of the weekend). The daily isoflavone intake (daidzein, genistein, glycitein and total isoflavones) and daily isoflavone intake per 1000 kcal of diet were assessed. RESULTSNo correlations between isoflavone intake levels and number of bowel movements per day were observed both in the case of intake and intake per 1000 kcal of diet. In the group of individuals declaring lack of abdominal pain, the higher intakes of daidzein (P = 0.0075), daidzein per 1000 kcal of diet (P = 0.0358) and total isoflavone (P = 0.0358) were stated, than in the group of individuals declaring abdominal pain. In the group of individuals declaring lack of constipations, the lower intakes of glycitein (P = 0.0213) and glycitein per 1000 kcal of diet (P = 0.0213) were stated, than in the group of individuals declaring presence of constipations. No differences were observed in isoflavone intake between groups of ulcerative colitis individuals declaring lack of flatulence and declaring presence of flatulence, as well as between groups declaring lack of tenesmus and declaring presence of tenesmus. CONCLUSIONThe moderate dietary isoflavone intake may be beneficial for individuals with ulcerative colitis in remission, however, before including it into recommendations, further prospective studies are needed.

Versatile optimization of the synthesis method and composition of Yb^3＋ and Tm^3＋ co-doped CaF2 nanoparticles as well as a novel biofunctionalization method were developed and evaluated. Through multistep synthesis, the luminescence intensity of the Tm3. activator was enhanced by more than 10-fold compared to standard one-step synthesis. The proposed methods were used to homogenously distribute the doping ions within the nanoparticle＇s volume and thus reduce luminescence quenching. Optimization of dopant ions concentration led to the selection of the most efficient visible and near-infrared up-converting nanoparticles, which were CaF2 doped with 10% Yb^3＋ 0.05% Tm^3＋ and 20% Yb3. 0.5% Tm^3＋, respectively. To illustrate the suitability of the synthesized nanoparticles as bio-labels, a dedicated biofunctionalization method was used, and the nanoparticles were applied for labeling and imaging of Candida albicans cells. This method shows great promise because of extremely low background and high specificity because of the presence of the attached molecules.

The aim of this work was to investigate the influence of Spirulina (Spirulina platensis) as a natural filler on thecuring characterization, morphology and mechanical, thermomechanical and thermal properties of naturalrubber (NR) based composites. Spirulina was introduced into NR mixture in amount of 0 phr, 10 phr and 30 *** vulcanization process was carried out at the determined process condition by using hydraulic press atoptimum vulcanization time (t90). It was noticed that Spirulina affected on the reduction of t90, and scorch time(t2) of the NR mixtures. Obtained vulcanizates were subjected to the number of tests e.g. scanning electronmicroscopy analysis, mechanical dynamical analysis, tensile test, hardness, and thermogravimetry. Generally, itwas found that Spirulina added in amount of 10 phr NR positively influenced on tensile strength (TSb), storagemodulus and hardness of obtained composites.
