This study investigates the effect of interaction between hardness of grains and modality of wheat (Triticum aestivum L.) presentation on starch digestion in broiler chickens. A digestive trial (without starvation) was conducted (d 34 to d 38) with 108 chickens (Ross) divided in 36 groups. Two varieties of wheat were included at 60 % in diets: Deben (soft, hardness = 27) and Folio (hard, hardness = 82). The first modality of presentation (Fine) corresponded to finely milled wheat (hammer mill, sieve of 2 mm). The second (Coarse) was related to coarsely milled wheat (hammer mill, sieve of 5 mm). The third dietary treatment (Whole) corresponded to 10 % whole wheat between d 10 to d 17, 20 % from d 17 to d 24 and 30 % after d 24. Hardness (varieties), modalities of presentation and their interaction did not influence ingested starch (p > 0.05). Hardness interacted significantly (p < 0.05) with presentation of wheat on excreted starch and starch digestibility. But quantities of digested starch were not significantly different between the six treatments (p > 0.05). The starch digestibility of Folio-Fine was significantly (p < 0.05) lower than five other treatments. Moreover, starch digestibility of Whole was (p < 0.05) better than Coarse for Deben only. On the other hand, starch digestibility was not significantly different between Deben-Coarse and Folio-Coarse (p > 0.05). Similarly, starch digestibility of Deben-Whole was not significantly different than Folio-Whole (p > 0.05). In conclusion, fine milling (2 mm) of hard variety (Folio) was involved in reduction of starch digestibility. [less ▲]

Health benefits of a diet rich in fruits and vegetables are attributed in part to their contents of phenolics and other antioxidant compounds. In this research, the extraction of phenolics and antioxidant compounds from black currant was optimised for different plant organs. The extraction solvent affected yield: aqueous acetone was better than methanol and acetate or glycine buffer. In aqueous buffer, maximum yields of total phenolics and antioxidant activities were obtained at pH 3. Extraction from lyophilised materials yielded extracts with higher phenolic contents and antioxidant activities. Stability of extracts made with acetate or glycine buffer was limited while the use of a mixture of acetone/acetic acid/water for extraction allowed a high phenolic content and antioxidant capacity in dry extract to be maintained for several months. This type of extract could be incorporated in functional food, beverage or dietary supplement. (c) 2007 Elsevier Ltd. All rights reserved. [less ▲]

BACKGROUND: Herpesviruses can be neutralized in vitro but remain infectious in immune hosts. One difference between these settings is the availability of immunoglobulin Fc receptors. The question therefore arises whether a herpesvirus exposed to apparently neutralizing antibody can still infect Fc receptor(+) cells. PRINCIPAL FINDINGS: Immune sera blocked murine gamma-herpesvirus-68 (MHV-68) infection of fibroblasts, but failed to block and even enhanced its infection of macrophages and dendritic cells. Viral glycoprotein-specific monoclonal antibodies also enhanced infection. MHV-68 appeared to be predominantly latent in macrophages regardless of whether Fc receptors were engaged, but the infection was not abortive and new virus production soon overwhelmed infected cultures. Lytically infected macrophages down-regulated MHC class I-restricted antigen presentation, endocytosis and their response to LPS. CONCLUSIONS: IgG Fc receptors limit the neutralization of gamma-herpesviruses such as MHV-68. [less ▲]

A new method for modeling the contact between the tool and the metal sheet for the incremental forming process was developed based on a dynamic explicit time integration scheme. The main advantage of this method is that it uses the actual contact location instead of fixed positions, e.g. integration or nodal points. The purpose of this article is to compare the efficiency of the new method, as far as accuracy and computation time are concerned, with finite element simulations using a classic static implicit approach. In addition, a sensitivity analysis of the mesh density will show that bigger elements can be used with the new method compared to those used in classic simulations. [less ▲]

The inhomogeneous mineral content and its topographical distribution on a microscopic scale are major determinants of the mechanical quality of trabecular bone. The kinetics of bone tissue deposition and resorption together with the kinetics of the mineralization process determine the distribution of mineral in the tissue. The heterogeneity of the mineral content is described by the well-established bone mineralization density distribution (BMDD), which is experimentally accessible, e.g., using quantitative electron backscattering imaging (qBEI). In the present work, we demonstrate that the shape of the BMDD histogram of trabecular bone reflects directly the mineralization kinetics. Based on the experimental BMDD data of trabecular bone from healthy human adults and using a mathematical model for the remodeling and the mineralization process, the following main results were obtained. The peaked BMDD reflects necessarily a two-phase mineralization process with a fast primary phase and a slow secondary phase where the corresponding time constants differ three orders of magnitude. The obtained mineralization law, which describes the increase in the mineral content in a bone packet as a function of time, provides information not only about the initial mineralization surge, but also about the slow increase afterwards on the time scale of years. In addition to the mineralization kinetics the turnover rate of the remodeling process has a strong influence on the peak position and the shape of the BMDD. The described theoretical framework opens new possibilities for an analysis of experimentally measured BMDDs with respect to changes caused by diseases or treatments. It a] lows addressing whether changes in the BMDD have to be attributed to a variation in the turnover rate which consequently affects the density distribution or to a primary disorder in the mineralization process most likely reflecting alterations of the organic matrix. This is of important clinical interest because it helps to find therapeutic approaches directly targeting the primary etiological defects to correct the patients' BMDD towards normal BMDD.

The Antarctic marine environment is characterized by challenging conditions for the survival of native microorganisms. Indeed, next to the temperature effect represented by the Arrhenius law, the viscosity of the medium, which is also significantly enhanced by low temperatures, contributes to slow down reaction rates. This review analyses the different challenges and focuses on a key element of life at low temperatures: cold-adapted enzymes. The molecular characteristics of these enzymes are discussed as well as the adaptation strategies which can be inferred from the comparison of their properties and three-dimensional structures with those of their mesophilic counterparts. As these enzymes display a high specific activity at low and moderate temperatures associated with a relatively high thermosensitivity, the interest in these properties is discussed with regard to their current and possible applications in biotechnology.

Experimental branching fractions for laser lines arising from excited states of 5d97s configuration of Au II have been determined by application of Laser Induced Breakdown Spectroscopy (LIBS). The experimental relative transition probabilities were converted into an absolute scale using theoretical values for the radiative lifetimes of the corresponding states, calculated in this work. Transition probabilities and radiative lifetimes have been determined by a relativistic Hartree - Fock method taking configuration interaction and core-polarization effects into account. A comparison of the present results with the available theoretical values has been made and shows a reasonable agreement although discrepancies are observed between theory and experiment for some transitions.
