Background/Aim: In previous studies, we described the beneficial effects of bifidobacteria-fermented milk in patients with ulcerative colitis (UC). Here, examined a live Bifidobacterium breve strain Yakult, probiotic contained milk, and galacto-oligosaccharide (GOS) as synbiotics UC patients. Methods: Forty-one mild to moderate were assigned two groups; one group was treated other not (control). The treatment ingested 1 g powder (109 CFU/g) three times day, 5.5 GOS once day for year.

The magnetic susceptibility and high-field magnetization process of NH 4 CuCl 3 with double chains have been measured using single crystals. No anomaly indicative the three-dimensional ordering is observed in data above 1.7 K. It found, by measurement down to 0.5 K, that contrast KCuCl TlCuCl , has a gapless ground state at zero field. curve two plateaus one-quarter three-quarters saturation magnetization, irrespective external field direction. origin attributed not anisotropy, but quantum...
Neutron elastic scattering experiments have been performed on the spin gap system TlCuCl$_3$ in magnetic fields parallel to $b$-axis. The Bragg peaks which indicate field-induced N\'{e}el ordering were observed for field higher than $H_{\rm g}\approx 5.5$ T at $Q=(h, 0, l)$ with odd $l$ $a^*-c^*$ plane. structure ordered phase was determined. temperature and dependence of peak intensities boundary obtained discussed connection a recent theory describes as Bose-Einstein condensation magnons.
Intramolecular interactions between ligands have been successfully applied as a novel tool for controlling various properties of series cis,trans-[Re(dmb)(CO)(2)(PR(3))(PR'(3))](+)-type complexes (dmb = 4,4'-dimethyl-2,2'-bipyridine), in the ground state and excited one-electron reduced form. For rhenium with two triarylphosphine ligands, P(p-XPh)(3), dmb ligand was sandwiched by four aryl rings having CH(aryl)-pi(pyridine)-pi(aryl) interactions. On other hand, one trialkylphosphite ligand,...

Four different types of molecular arrangements can be formed by one-pot synthesis, depending on the type counter cation used, when a new anionic tris(biimidazolato)nickel(II) complex is used to form network held together hydrogen bonds. The connections occur through biimidazolate ligands, which act as bond donor well acceptor (see scheme).

Partially hydrolysed guar gum (PHGG) is a water-soluble dietary fibre that non-digestible in the upper gastrointestinal tract. It believed PHGG benefits health of hosts by altering colonic microbiota and stimulating short-chain fatty acid (SCFA) production. However, it remains unclear which bacteria ferment human large intestine.
