Phenylpropanoids including diverse compounds, such as monolignols and hydroxycinnamic acids (HCAAs), are essential for land plants to protect them against abiotic stresses, and create physical and chemical barriers to pathogen infection. However, the production control of these compounds against to pathogens has been poorly understood. Previously we showed that a MAMP (microbe-associated molecular pattern) -responsive MAPK (mitogen-activated protein kinase) cascade (MKK4-MPK3/MPK6) comprehensively induced the expression of cinnamate/monolignol synthesis genes in rice cells...

Animal by-product rendering establishments are still relevant industries worldwide. Animal by-product meal safety is paramount to protect feed, animals, and the rest of the food chain from unwanted contamination. As microbiological contamination may arise from inadequate processing of slaughterhouse waste and deficiencies in good manufacturing practices within the rendering facilities, we conducted an overall establishment's inspection, including the product in several parts of the process.An evaluation of the Good Manufacturing Practices (GMP) was carried out, which included the location and access (i...

Background: Quality of life (QoL) is commonly assessed in inflammatory bowel disease (IBD); the relationship of QoL within IBD states and relative to others has not been comprehensively evaluated. This systematic review, published across 2 papers, evaluates 5 key QoL comparisons. Part I, presented here, examines between-disease comparisons: (1) IBD/healthy(general) population and (2) IBD/other medically ill groups. Part II examines within-disease comparisons: (3) active/inactive disease, (4) ulcerative colitis/Crohn's disease, and (5) change over time...

Amyloid-β (Aβ) protein aggregates through a complex pathway to progress from monomers to soluble oligomers and ultimately insoluble fibrils. Due to the dynamic nature of aggregation, it has proven exceedingly difficult to determine the precise interactions that lead to the formation of transient oligomers. Here, a statistical thermodynamic model has been developed to elucidate these interactions. Aβ1-42 was simulated using fully-atomistic replica exchange molecular dynamics. We use an ensemble of approximately 5×105 configurations taken from simulation as input in a self-consistent field theory that explicitly accounts for the size, shape and charge distribution of both the amino acids comprising Aβ and all molecular species present in solution...

In the past few decades, emf (E) measurements using improved electrochemical cells have afforded the derivation of mean ionic activity coefficients (γ± 's) of very dilute solutions of binary electrolytes, within the 10-6 - 10-3 molar range (Malatesta et al., J. Sol. Chem. 1994, 23, 11). Such measurements are especially important for highly charged electrolytes whose behavior at very low concentration is not yet fully understood, and whose γ± values, derived from E data, have been claimed by Malatesta and coworkers to exhibit "negative deviations" from the Debye-Hückel (DH) limiting law...

Individuals with disabilities are regarded as a highly vulnerable population group, particularly as far as oral health is concern. However, few studies have assessed the impact of the oral condition on the quality of life of these individuals. Therefore, the aim of this study is to expand knowledge on the oral health status of the Portuguese adults with mild intellectual disability, and to assess how the patient's oral health is related to their quality of life. A sample of 240 adults with mild intellectual disabilities linked to the Portuguese Federation for Intellectual Disability, were interviewed using a previously validated version of the Oral Health Impact Profile...

Vortical cross-step filtration in suspension-feeding fish has been reported recently as a novel mechanism, distinct from other biological and industrial filtration processes. Although crossflow passing over backward-facing steps generates vortices that can suspend, concentrate, and transport particles, the morphological factors affecting this vortical flow have not been identified previously. In our 3D-printed models of the oral cavity for ram suspension-feeding fish, the angle of the backward-facing step with respect to the model's dorsal midline affected vortex parameters significantly, including rotational, tangential, and axial speed...

Gari, a fermented and dried semolina made from cassava, is one of the most common foods in West Africa. Recently introduced biofortified yellow cassava containing provitamin A carotenoids could help tackle vitamin A deficiency prevalent in those areas. However there are concerns because of the low retention of carotenoids during gari processing compared to other processes (e.g. boiling). The aim of the study was to assess the levels of true retention in trans-β-carotene during gari processing and investigate the causes of low retention...
