  text: 'To evaluate the suitability of an analytical instrument, essential figures
    of merit such as the limit of detection (LOD) and the limit of quantification
    (LOQ) can be employed. However, as the definitions k nown in the literature are
    mostly applicable to one signal per sample, estimating the LOD for substances
    with instruments yielding multidimensional results like electronic noses (eNoses)
    is still challenging. In this paper, we will compare and present different approaches
    to estimate the LOD for eNoses by employing commonly used multivariate data analysis
    and regression techniques, including principal component analysis (PCA), principal
    component regression (PCR), as well as partial least squares regression (PLSR).
    These methods could subsequently be used to assess the suitability of eNoses to
    help control and steer processes where volatiles are key process parameters. As
    a use case, we determined the LODs for key compounds involved in beer maturation,
    namely acetaldehyde, diacetyl, dimethyl sulfide, ethyl acetate, isobutanol, and
    2-phenylethanol, and discussed the suitability of our eNose for that dertermination
    process. The results of the methods performed demonstrated differences of up to
    a factor of eight. For diacetyl, the LOD and the LOQ were sufficiently low to
    suggest potential for monitoring via eNose. '

  text: Diet processing impacts on starch properties, such as the degree of starch
    gelatinization. This affects digestibility, as shown in laboratory mice fed either
    a pelleted or an extruded diet. In the present study, the morphology of starch
    particles throughout the digestive tract of mice was visualized. Thirty-two female
    C57BL/6J mice were used for a feeding trial. They were fed a commercial maintenance
    diet for laboratory mice, which was available in pelleted and extruded form, for
    seven weeks. The mice were sacrificed after the feeding period, and chyme samples
    were collected from five sites (stomach, anterior and posterior small intestine,
    caecum, colon). Samples of diets, chyme and faeces were analyzed via stereomicroscopy
    (stained with Lugol’s iodine) and scanning electron microscopy (SEM). The starch
    granules appeared more compact in the pelleted diet, showing first signs of degradation
    only in the small intestine. The caecum content of both diets group was intensively
    stained, particles as well as fluid phase, indicating that it contained mainly
    starch. The SEM pictures of caecum content showed abundant bacteria near starch
    particles. This suggests selective retention of prae-caecally undigested starch
    in the murine caecum, likely the site of microbial fermentation.

  text: Physiological consequences of adaptation to and continued feeding of a high-energetic
    diet were studied in eight non-pregnant, non-lactating dairy Holstein cows over
    a period of 16 weeks. The first six weeks served as an adaptation period from
    the low energetic straw-based diet (3.8 MJ NEL/kg DM) to the high-energetic ration
    (7.5 MJ NEL/kg DM). Intake of dry matter (DM) increased with dietary energy concentration
    from 9 to 20 kg/d up to week 9 to 12 and decreased thereafter. The initial live
    weight (LW) of 550 ± 60 kg was increased linearly and corresponded to an average
    daily LW gain of 2.3 ± 0.3 kg. Energy balance increased approximately nine-fold
    to a maximum of 114 MJ NEL/d in week 10. Ruminal fermentation pattern was completely
    changed from an acetate dominating profile to a propionate based one, which was
    paralleled by a marked increase in the rumen fluid endotoxin concentration. Unlike
    blood glucose concentration, which increased continuously, that of cholesterol
    and triglycerides started to increase after an initial stagnation. In conclusion,
    both ruminal adaptation to a high-energetic diet and the continued feeding of
    such a diet induced digestive and metabolic adaptations in non-pregnant, non-lactating
    cows characterised by a progressing positive energy balance.
