The gene designated BAB_RS23470 in the Brucella abortus 2308 genome encodes an ortholog of the cation diffusion facilitator family protein EmfA which has been linked to resistance to Mn toxicity in Rhizobium etli. A B. abortus emfA null mutant derived from strain 2308 displays increased sensitivity to elevated levels of Mn in the growth medium compared to the parent strain, but wild-type resistance to Fe, Mg, Zn, Cu, Co and Ni.

In this review, we focus on how full‐length chromogranin A and its peptides, including PST, vasostatin‐1, CST, and serpinin, as important modulators of cardiovascular functions, immunometabolism, and cancer. Abstract Chromogranin A (CgA)—the index member of the chromogranin/secretogranin secretory protein family—is ubiquitously distributed in endocrine, neuroendocrine, and immune cells.

Carbofuran residue in vegetables is a concern to human health. Direct competitive enzyme‐linked immunosorbent assay (dcELISA) and dipstick immunoassay were developed in the present study. The dcELISA showed a 50% inhibition concentration (IC50) and working range of 1.3 and 0.2 to 7.5 ng/mL, respectively, while the cutoff value of dipstick immunoassay was 20 ng/mL.

A multilayer film containing star anise essential oil and thymol coating layers (SAEO and TH, respectively), with insect repellent and antimicrobial properties, has been developed using bar coating and adhesive lamination processes. Our previous study reported the in vitro activities of this polypropylene film (PP)/SAEO/polyethylene terephthalate film (PET)/TH/low‐density polyethylene film (LDPE) multilayer film.

The present work studied, for the first time, the effect of two technologies on the hydration and germination process of beans: ionizing irradiation and ultrasound. In addition, this work proposed a possible biological effect of ultrasound to describe its effect on grain hydration. Carioca beans were irradiated at doses of 2.3 and 3.8 kGy using γ‐rays, establishing different metabolic activities for the beans.

The aim of this study was to examine the resistome characteristics of Salmonella spp. Contamination found in raw retail beef, pork, and chicken samples collected in Hanoi, Vietnam. Approximately 28% (25/90) of samples tested carried Salmonella bacteria. A total of 13/25 (52%) of these Salmonella bacteria were resistant to at least one antibiotic and 9/25 (36%) of the isolates were found to be multidrug resistant.

The current study investigates the effect of Lactobacillus reuteri and Lactobacillus plantarum combined with water extract of garlic on microbial growth, chemical changes, and sensory attributes in ground beef samples at refrigeration condition (+4°C) up to 12 days of storage. in vitro study revealed that garlic extract combined with L. reuteri or L. plantarum caused 2.13 and 2.57 log reduction in the Listeria monocytogenes count, respectively. Combination of L.

Dysentery is a major health threat that dramatically impacts childhood morbidity and mortality in developing countries. Various pathogenic agents cause dysentery, such as Shigella spp. and Escherichia coli, which are very closely related if not identical species. Sensitive and precise detection and identification of the infectious agent is important to target the best therapeutic strategy, but the differential diagnosis of these two groups remains a challenge using conventional methods.

To strengthen the burden estimates for chronic sequelae of foodborne illness, we conducted a scoping review of the current literature for common foodborne pathogens and their associated sequelae. We aim to describe the current literature and gaps in knowledge of chronic sequelae associated with common foodborne illnesses. A comprehensive search was conducted in PubMed, EMBASE, and Web of Science for peer-reviewed articles published January 1, 2000 to April 1, 2018.

Free‐range poultry farms have a high risk of introduction of avian influenza viruses (AIV), and it is presumed that wild (water)birds are the source of introduction. There is very scarce quantitative data on wild fauna visiting free‐range poultry farms. We quantified visits of wild fauna to a free‐range area of a layer farm, situated in an AIV hot‐spot area, assessed by video‐camera monitoring.

Molecular imprinted polymers prepared by Pickering emulsion method with lignin as stable particle were used as dispersants in matrix solid phase dispersion, followed by ultra performance liquid chromatography‐tandem mass spectrometry analysis to research the degradation behavior of matrine in soil. The molecular imprinted polymers have regularly morphology and uniformly particles. Moreover, the adsorption experiments and the conditions of matrix solid phase dispersion were discussed.

The chronically inflamed mucosa in patients with chronic rhinosinusitis (CRS) can additionally be infected by bacteria, which results in an acute exacerbation of the disease (AECRS). Currently, AECRS is universally treated with antibiotics following the guidelines for acute bacterial rhinosinusitis (ABRS), as our understanding of its microbiology is insufficient to establish specific treatment recommendations.

Abstract

Background

Mislabelling and substitution of ingredients in food supplements is a growing concern for regulators, businesses and consumers. Whilst there is a body of literature that has considered food and drink substitution and mislabelling, there is limited published research on the compliance of food supplements with regulatory requirements.
