Smoked salmon is a highly appreciated delicatessen product. Nevertheless, this ready-to-eat (RTE) product is considered at risk for Listeria monocytogenes, due to both the prevalence and growth potential of this bacteria on the product. Biopreservation may be considered a mild and natural effective strategy for minimizing this risk. In this study, we evaluated the following three potential bioprotective lactic acid bacterial strains against L. monocytogenes in three smoked salmon types with different physicochemical characteristics, primarily fat, moisture, phenol and acid acetic content: two bacteriocin-like producers that were isolated from smoked salmon and identified as Lactobacillus curvatus and Carnobacterium maltaromaticum and a recognized bioprotective bacteriocin producer from meat origin, Lactobacillus sakei CTC494. L. sakei CTC494 inhibited the growth of L. monocytogenes after 21 days of storage at 8 °C in all the products tested, whereas L. curvatus CTC1742 only limited the growth of the pathogen (<2 log increase). The effectiveness of C. maltaromaticum CTC1741 was dependent on the product type; this strain limited the growth of the pathogen in only one smoked salmon type. These results suggest that the meat-borne starter culture, L. sakei CTC494, may potentially be used as a bioprotective culture to improve the food safety of cold-smoked salmon.

Maternal smoking increases adverse risks for both the mother's pregnancy and the unborn child and remains disproportionately high among some Indigenous peoples. Decreasing smoking among pregnant Indigenous women has been identified as a health priority in New Zealand because of wide inequities in smoking-related harms. Using pre- and post-intervention questionnaires, this feasibility study assessed the acceptability and potential efficacy of a novel cessation program designed for Indigenous women by Indigenous experts utilizing traditional knowledge and practice.

Despite the widespread consumption of salmon products, an all-round microbiological survey on fresh salmon and smoked salmon products sold on the market directly to consumers remains to be undertaken. The present study conducted a comprehensive microbial investigation employing both conventional cultivation-based techniques and 16S rRNA amplicon sequencing. A total of 120 fresh salmon and 95 smoked salmon products were systematically collected across all four seasons (spring, summer, fall, and winter), accompanied by temperature assessments of each product's interior.

Unlabelled: It is known that monocytes can make a significant contribution to the development of chronic obstructive pulmonary disease (COPD); however, the features of the transcriptome of these cells associated with the disease remain poorly understood.
Aim: : The aim of the study was to perform monocyte transcriptome analysis for identification of differentially expressed genes and key disturbances in biological processes in these cells in COPD.
