    Abstract The rheological performance of bacterial cellulose and carboxymethyl cellulose (BC:CMC) dry formulations with mass ratios of 1:1, 1:0.75 and 1:0.5 was compared with that of a commercial xanthan gum. The zero-shear viscosity and the yield stress of these hydrocolloids, at concentrations ranging from 0.001% to 0.5% (w/w), were determined by fitting the Cross and Herschel-Bulkley models to the flow curves. Only BC:CMC formulations presented a measurable yield stress, the highest value (1.54 ± 0.17 Pa) being obtained for the 1:0.5 ratio at a concentration of 0.5%. This formulation also presented the highest values of dynamic moduli, namely G′, indicating a stronger solid-like character. Contrarily to xanthan gum, BC:CMC formulations' viscosity profile in aqueous solution was not considerably affected by the pH (in the range from 2.8 to 10.4), the ionic strength (NaCl from 0 mM to 350 mM) or the temperature (6–80 °C). Food grade sunflower oil-in-water emulsions (20% oil) were prepared with 0.3% of the test hydrocolloids, with 150 mM NaCl and pH 3.5. Emulsions with BC:CMC in the ratios of 1:0.75 and 1:0.5 had smaller droplets, stronger solid-like behaviour and resisted centrifugation with little phase separation. These results confirm the high performance of the dry BC:CMC formulations in the stabilization of colloidal systems.

    Abstract Some members of the Firmicutes phylum, including many members of the human gut microbiota, are able to differentiate a dormant and highly resistant cell type, the endospore (hereinafter spore for simplicity). Spore-formers can colonize virtually any habitat and, because of their resistance to a wide variety of physical and chemical insults, spores can remain viable in the environment for long periods of time. In the anaerobic enteric pathogen Clostridioides difficile the aetiologic agent is the oxygen-resistant spore, while the toxins produced by actively growing cells are the main cause of the disease symptoms. Here, we review the regulatory circuits that govern entry into sporulation. We also cover the role of spores in the infectious cycle of C. difficile in relation to spore structure and function and the main control points along spore morphogenesis.

    Abstract The lympho-epithelial Kazal-type inhibitors (LEKTI) are key to control skin turnover, and their absence causes Netherton syndrome. For clinical sample testing of LEKTI-based therapies, a robust analytical method to measure LEKTI-like activity in skin is required. This work reports on the development of a back-titration method to determine incremental LEKTI-like activity in skin samples. The method meets the analytical requirements for study sample testing, and reliable quantification can be achieved with negligible skin matrix interference. This assay does not provide analyte identity, but it can be used to measure treatment-driven increments of LEKTI-like activity within the skin epidermis.

    Abstract This volume presents new topics from Chinese history of the last 1400 years from a broad range of fields such as politics, religion, society, economy and culture. The refreshing eight articles give new insights on events as different as the inter-religious court debates of the Tang, the Jiaqing reform of the Qing, the China display on the Chicago World Fair in 1893, Christianity and state-building in Chaozhou, the Taiwan salt trade, Chinese indentured labour in World War I in France, Chinas rise and current internet regulation. This book highlights the complexity of multi-level interaction of different agents in the center and periphery of China, inside and outside China, contributing to intellectual debates, political and social dynamics, economy structure, modernization, identity building and interaction with the outside

    Abstract The total mixed ration (TMR) is currently a widespread method to feed dairy cows. It is a mixture of raw fodder and concentrate feed that can be contaminated by several mycotoxins. The main aim of this paper was to provide a critical review on TMR mycotoxin occurrence and its usefulness to monitor and control them on-farm. Aflatoxins, zearalenone, deoxynivalenol, T-2 toxin and fumonisins (regulated mycotoxins) are the most prevalent mycotoxins evaluated in TMR. Nonetheless, several emerging mycotoxins represent a health risk at the animal level regarding their prevalence and level in TMR. Even when measured at low levels, the co-occurrence of mycotoxins is frequent and synergistic effects on animal health are still underevaluated. Similar to the animal feed industry, on-farm plans monitoring mycotoxin feed contamination can be developed as a herd health management program. The estimated daily intake of mycotoxins should be implemented, but thresholds for each mycotoxin are not currently defined in dairy farms.

    Abstract Generic cosmetic creams (oil-in-water emulsions) were prepared using dry Bacterial Cellulose and Carboxymethyl Cellulose (BC:CMC) to study the possibility of partially or completely replacing surfactants, while ensuring a long-term stability and the required organoleptic characteristics. BC:CMC was benchmarked against two hydrocolloidal Avicel products (PC-591 and PC-611), commonly used as thickeners and stabilizing aids in cosmetics production. The emulsions were then characterized regarding storage stability, rheology, texture and microscopic features.The full replacement of 5.5 % surfactants with only 0.75 % BC:CMC consistently showed similar results to those obtained with surfactants, namely concerning viscosity and texture. Although producing emulsions with larger oil droplets, BC:CMC provided for a very effective stabilization through a Pickering effect and by structuring the continuous phase. The more effective Avicel tested (PC-591) required a higher concentration (1.5 %) to achieve similar rheological profile but was ineffective in stabilizing the oil phase in a surfactant-free formulation with the adopted protocol. By replacing surfactants, dry BC:CMC matches a strong market need since both end users and manufacturers increasingly seek natural ingredients for cosmetic formulations.
