Amelioration of Smoke Taint in Wine via Addition of Molecularly Imprinted Polymers during or after Fermentation.

The adsorbents used to remove taint compounds from wine can also remove constituents that impart desirable color, aroma, and flavor attributes, whereas molecularly imprinted polymers (MIPs) are tailor-made to selectively bind one or more target compounds. This study evaluated the potential for MIPs to ameliorate smoke taint in wine via removal of volatile phenols during or after fermentation. The addition of MIPs to smoke-tainted Pinot Noir wine (for 24 h with stirring) achieved 35-57% removal of guaiacol, 4-methylguaiacol, cresols, and phenol, but <10% of volatile phenol glycoconjugates were removed and some wine color loss occurred.

ProQ-dependent activation of virulence genes mediated by post-transcriptional control of PhoP synthesis.

Unlabelled: Gastrointestinal disease caused by is associated with the pathogen's ability to replicate within epithelial cells and macrophages. Upon host cell entry, the bacteria express a type-three secretion system encoded within pathogenicity island 2, through which host-manipulating effector proteins are secreted to establish a stable intracellular niche. Transcription of this intracellular virulence program is activated by the PhoPQ two-component system that senses the low pH and the reduced magnesium concentration of host cell vacuoles.

Physical learning environments' supportiveness to innovative pedagogies: students' and teachers' experiences.

Research into the relationship between innovative physical learning environments (PLEs) and innovative psychosocial learning environments (PSLEs) indicates that it must be understood as a network of relationships between multiple psychosocial and physical aspects. Actors shape this network by attaching meanings to these aspects and their relationships in a continuous process of gaining and exchanging experiences. This study used a psychosocial-physical, relational approach for exploring teachers' and students' experiences with six innovative PLEs in a higher educational institute, with the application of a psychosocial-physical relationship (PPR) framework.

Influencing adolescents' attitudes towards nicotine products: A systematic review.

Use of nicotine can harm adolescents' brains and increase risk for future addiction to other drugs. Several international studies show that an acceptable attitude towards nicotine products increases the initiation or use of the products. Adolescents have limited or distorted knowledge about nicotine products.

Impact of MALDI-TOF MS identification on anaerobic species and genus diversity in routine diagnostics.

Objectives: Introduction of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) has revolutionized bacterial identification in the last decade. In 2013, MALDI-TOF MS was implemented for the identification of anaerobic bacteria at our laboratory. This study analyzed the impact of MALDI-TOF MS on the number of different anaerobic genera and species identified in diagnostics.
