Two experiments were conducted to evaluate the effects of adding an exogenous fibrolytic enzyme (FE) on ruminal pH and fermentation, digestibility, and growth performance of feedlot beef cattle fed a finishing diet containing wheat dried distillers grains with solubles (DDGS). In Exp. 1, 4 ruminally cannulated Angus heifers (average BW of 807 ± 93.9 kg) were used in a replicated 4 × 4 Latin squ...

A sensitive, selective colorimetric Fe(3+) detection method has been developed by using pyrophosphate functionalized gold nanoparticles (P(2)O(7)(4-)-AuNPs). Gold nanoparticles were prepared by reducing HAuCl(4) with sodium borohydride, in the presence of Na(4)P(2)O(7). IR spectra suggested that pyrophosphates were capped on the surface of the gold nanoparticles. Aggregation of P(2)O(7)(4-)-AuN...

BACKGROUND Exhaled nitric oxide (FE(NO)) is raised in asthmatic children, but there are inconsistencies in the relationship between FE(NO) and characteristics of asthma, including atopy, increased airway responsiveness (AR), and airway inflammation. The aim of this study was to investigate the relationship between FE(NO) and asthma, atopy, and increased AR in children. METHODS One hundred and...

BACKGROUND AND OBJECTIVES Diarrhea is a common complication of enteral nutrition (EN), which affects recovery and prolongs the length of hospital stay (LOHS). To investigate the effect of fiber and probiotics in reducing diarrhea associated with EN in postoperative patients with gastric cancer (GC), the authors designed this prospective randomized-controlled trial. METHODS AND STUDY DESIGN Th...

The Tropical North Atlantic (TNAtl) plays a critical role in the marine nitrogen cycle, as it supports high rates of biological nitrogen (N(2)) fixation, yet it is unclear whether this process is limited by the availability of iron (Fe), phosphate (P) or is co-limited by both. In order to investigate the impact of nutrient limitation on the N(2)-fixing microorganisms (diazotrophs) in the TNAtl,...

The title dinitrosyl iron diphosphane complex, [Fe(NO)(2)(C(18)H(12)Cl(3)P)(2)] or Fe(NO)(2)L(2) [L = P(C(6)H(4)-p-Cl)(3)] belongs to the family of metal dinitrosyl compounds with the general formula Fe(NO)(2)(L)(x), referred to collectively as dinitrosyl iron compounds (DNICs). The iron atom is tetra-hedrally coordinated by two phosphane ligands and two NO groups with Fe-N-O bond angles of 178...
