Feeding measures with a potential to improve N efficiency in dairy cattle husbandry were studied at two levels of undegradable protein balance (OEB). In each of the two experiments, two simultaneous Latin squares were conducted, each with three treatments and three lactating Holstein cows. Decreasing the OEB of the diet improved N efficiency and resulted in lower N excretion per kg milk. To avoid a negative effect of the decreased OEB on the production results, spreading the concentrate intake (as TMR or in five meals) seemed to be most promising, although only few significant effects were found. The use of protected protein sources or the addition of clinoptilolite were not successful in improving N-efficiency. The rather well balanced mixed basal diet and the large variation between animals seem to have hampered the assessment of such significant influences.

Nondestructive Mechanical Characterization of Bioengineered Tissues by Digital Holography.

Mechanical properties of engineered connective tissues are critical for their success, yet modern sensors that measure physical qualities of tissues for quality control are invasive and destructive. The goal of this work was to develop a noncontact, nondestructive method to measure mechanical attributes of engineered skin substitutes during production without disturbing the sterile culture packaging. We optimized a digital holographic vibrometry (DHV) system to measure the mechanical behavior of Apligraf living cellular skin substitute through the clear packaging in multiple conditions: resting on solid agar as when the tissue is shipped, on liquid media in which it is grown, and freely suspended in air as occurs when the media is removed for feeding.

Sociocultural factors play a significant role in the development of body image distress and disordered eating behavior in diverse populations, including men. One group which seems to be at increased risk, is sexual minority men. However, these factors have rarely been studied outside of Western populations.

Background: COVID-19 lockdown measures have profoundly altered lifestyle habits, exposing individuals to significant health risks Aim: This study aims to assess the impact of quarantine measures in Tunisia, with a focus on examining changes in dietary habits, levels of physical activity, psychological patterns, and factors contributing to weight gain.
Methods: This is a cross-sectional study involving 1,016 participants and employed a mixed-methods approach to gather data on dietary habits, physical activity levels, and psychological indicators. Statistical analyses, including binary logistic regression, were conducted to identify independent risk factors associated with weight gain during the quarantine period.

Our study explores the potential relationship between infant feeding practices and settlement complexity in the Roman Empire through high-resolution Bayesian-modeled stable isotope measurements from incremental dentine. We compiled isotopic data from permanent first molars of individuals from various Roman sites: five from Bainesse (UK), 30 from Thessaloniki (Greece), along with new carbon and nitrogen isotope analyses from four individuals from Pompeii and six from Ostia Via del Mare (AVM). Our results reveal significant inter-site variability in breastfeeding durations, ranging from 1.
