An experiment was conducted to study the effects of dietary supplementation of 1,3-diacylglycerol (DAG) as an emulsifier in a low-density diet on growth performance, nutrient digestibility, blood characteristics, and meat quality in broilers. A total of 480 1-day-old male 308 Ross broiler chicks were randomly allocated into 1 of the following 5 treatments: Control, fed a basal diet (CON), basal diet minus 100 kcal ME diet (LE), T1 (LE + 0.075% 1,3-DAG), T2 (LE + 0.10% 1,3-DAG), and T3 (LE + 0.15% 1,3-DAG)...

In order for a lignocellulosic bioenergy feedstock to be considered sustainable, it must possess a high rate of growth to supply biomass for conversion. Despite the desirability of a fast growth rate for industrial application, it is unclear what effect growth rate has on biomass composition or saccharification. We characterized Klason lignin, glucan, and xylan content with response to growth in Corymbia interspecific F1 hybrid families (HF) and parental species Corymbia torelliana and C. citriodora subspecies variegata and measured the effects on enzymatic hydrolysis from hydrothermally pretreated biomass...

To improve the understanding of NH3 variation in urban Beijing, high temporal resolution (1-min averaged) NH3 data derived during the summer of 2009 were analyzed. The results indicated that after rain there was generally an increase in NH3 concentration. The analysis of the 1-min data revealed that a weak but significant linear correlation existed between NH3 and NOx in August, indicating a connection between NH3 concentrations and traffic levels during summer. This was further supported by peak NH3 levels approximately coinciding with morning rush hours...

Silver barb (Puntius gonionotus) is considered a promising medium carp species for freshwater aquaculture in Asia. This study in silver barb was carried out to evaluate the effects of total or partial substitution of dietary fish oil (FO) with linseed oil (LO) on growth, nutrient utilization, whole-body composition, muscle and liver fatty acid composition. Fish (12.1±0.4g of initial body weight) were fed for 60days with five experimental iso-proteinous, iso-lipidic and iso-caloric diets in which FO (control diet) was replaced by 33...

Chen Lin, Fang Zhigang
This paper focused on two rhodamine chemosensors for cysteine optical sensing. To minimize their photobleaching caused by excitation light, up-conversion NaYF4:Yb(3+)/Er(3+) nanocrystals were prepared and used as excitation host. Photophysical measurement on this host and the two chemosensors suggested that chemosensor absorption matched well with host emission. An efficient energy transfer between them was discussed and confirmed by their spectral analysis and emission lifetime comparison. Job's plot suggested that our chemosensors followed a simple recognition mechanism towards cysteine with binding stoichiometry of 1:1...

Photoacoustic tomography has emerged as a promising non-invasive imaging technique that integrates the merits of high optical contrast with high ultrasound resolution in deep scattering medium. Unfortunately, the blood background in vivo seriously impedes the quality of imaging due to its comparable optical absorption with contrast agents, especially in conventional linear photoacoustic imaging modality. In this study, we demonstrated that two hybrids consisting of gold nanorods (Au NRs) and zinc tetra(4-pyridyl)porphyrin (ZnTPP) exhibited a synergetic effect in improving optical absorption, conversion efficiency from light to heat, and thermoelastic expansion, leading to a notable enhancement in both linear (four times greater) and nonlinear (more than six times) photoacoustic signals as compared with conventional Au NRs...

We report a laser-pumped (4)He atomic magnetometer with light shift suppression through the atomic sensor itself. A linearly polarized light is used to optically align the (4)He metastable atoms and we monitor the magneto-optical double resonance (MODR) signals produced by the left- and right-circularly orthogonal components. It is shown that light shift leads to the atomic alignment to orientation conversion effect, and thus, the difference between the two MODR signals. One of these two MODR signals is locked at the Larmor frequency and is used to measure the ambient magnetic field, while the differential signal is, simultaneously, fed back to suppress the light shift...

The simultaneous conversion of cyclopentanone and m-cresol has been investigated on a series of solid acid catalysts. Both compounds are representative of biomass-derived streams. Cyclopentanone can be readily obtained from sugar-derived furfurals via Piancatelli rearrangement under reducing conditions. Cresol represents the family of phenolics, typically obtained from the depolymerization of lignin. In the first biomass conversion strategy proposed here, furfural is converted in high yields and selectivity to cyclopentanone (CPO) over metal catalysts such as Pd-Fe/SiO2 catalyst at 600 psia H2 and 150oC...

Glycopolymers attached to a surface possess the ability to bind to certain carbohydrate binding proteins in a highly specific manner, and because of this, the fabrication of glycopolymer-modified surfaces has evolved as an effective route toward bioresponsive systems. Poly(N-3,4-dihydroxybenzenethyl methacrylamide-co-2-(methacrylamido) glucopyranose) copolymers, containing sugar and catechol functionalities, are for the first time successfully prepared in a well-controlled manner via room temperature single-electron transfer initiation and propagation through radical addition fragmentation chain transfer technique...

Supplementation of grass-fed cattle with low-cost feeding alternatives may be an attractive way to improve efficiency of cattle production. We hypothesized that inclusion of crude glycerin (CG) in supplements provided to grass-fed cattle could improve feed conversion without negative effects on growth performance while reducing methane emissions. Our hypothesis was tested using Nellore bulls grazing tropical pasture ( = 50; initial BW of 427 ± 19.41 kg; age of 17 ± 2 mo) supplemented with increasing concentrations (0, 70, 140, 210, and 280 g/kg DM basis of supplement) of CG and corn gluten replacing corn grain...

Animal proteins are commonly used in extruded dog foods. Plant-based proteins have a more consistent nutrient profile than animal sources but may contain antinutritional factors, including trypsin inhibitors and oligosaccharides. Bioprocessed soy protein (SP; HP-300; Hamlet Protein, Inc., Findlay, OH) is a processed soy-based product with low antinutritional factor concentrations and high protein quality. The objective was to evaluate the effects of SP on apparent total tract macronutrient digestibility, fecal characteristics, and fecal fermentative end products...

Two studies evaluated effects of replacing corn with a pellet containing alkaline treated corn stover, dried distillers' grains plus solubles (DDGS), and distillers' solubles on total tract digestion and performance of finishing cattle. Experiment 1 used 4 ruminally fistulated steers in a 4 × 6 Latin rectangle to evaluate total tract digestion. Treatments consisted of a control (CON) containing 50.3% dry-rolled corn (DRC), 40% modified distillers' grains plus solubles (MDGS), and 5% untreated corn stover. The next 2 treatments replaced 25% DRC (DM basis) with either a CaO-treated stover pellet (STOVPEL) or a pellet consisting of 64% CaO-treated corn stover, 18% DDGS, and 18% corn distillers' solubles (COMBPEL)...

The objectives were to assess the impact of heat stress and to develop a model for genetic evaluation of growth heat tolerance in Angus cattle. The American Angus Association provided weaning weight (WW) and yearling weight (YW) data, and records from the Upper South region were used because of the hot climatic conditions. Heat stress was characterized by a weaning (yearling) heat load function defined as the mean temperature-humidity index (THI) units greater than 75 (70) for 30 (150) d prior to the weigh date...

There is increasing interest in the synthesis of low molecular weight heparin and heparan sulfate mimetic polymers because of their various potential biomedical applications. The functional activity of heparin and heparan sulfate is believed to arise from the presence of a number of functional groups, such as hydroxyl, carboxylate and sulfate groups. The design and synthesis of novel heparin-mimetic polymers with a particular functionality poses a formidable challenge and requires carefully control of the selective conversion of functional groups on the polymer chain...

The influences of temperature and residence times on the conversion and product distribution during hydrothermal carbonisation of municipal solid wastes were investigated. Analysis of variance and reaction severity were used to comprehensively analyse the experimental results. Analysis results showed both reaction temperature and residence time had varying degrees of impact on production distribution and hydrochars characteristic, while the effect of combine temperature and time was negligible. It is novel to find that the products yield was a linear function of the logarithm of the reaction ordinate...

BACKGROUND: Acquired thrombotic thrombocytopenic purpura (TTP) is a rare thrombotic microangiopathy due to the development of autoantibodies against the VWF-cleaving protease ADAMTS13. ADAMTS13-specific circulating immune complexes (CICs) have been described in patients with acquired TTP, but their clinical relevance remained to be established. The aim of this study was to assess the association between ADAMTS13-specific CICs and ADAMTS13-related measurements, clinical and laboratory markers of disease severity, and occurrence of TTP relapse, in autoimmune TTP patients...
