Here, we explored the influences of thyme microcapsules on the growth, gene expression, and histamine accumulation by Proteus bacillus isolated from smoked horsemeat sausage. RT-qPCR was employed to evaluate the gene expression level of histidine decarboxylase (HDC) cascade-associated genes. We used HPLC to monitor histamine concentration both in pure culture as well as in the processing of smoked horsemeat sausage. Results showed that histamine accumulation was suppressed by thyme microcapsule inhibitory effect on the histamine-producing bacteria and the reduction in the transcription of hdcA and hdcP genes. Besides, compared with thyme essential oil (EO), thyme microcapsules exhibited higher antibacterial activity and had a higher score for overall acceptance. Therefore, the addition of thyme microcapsules in Xinjiang smoked horsemeat sausage inhibits histamine accumulation.

Purpose: Elevated level of Lipocalin-2 (LCN2), a new acute phase adipokine, was described after ischemic stroke. A number of researchers feel as though that LCN2 originated from the infiltrating neutrophils and other cells in brain after stroke. Others measured elevated LCN2 expression in arteriosclerotic plaque. Therefore we have investigated LCN2 relative gene expression level of blood neutrophil granulocytes in patients with ischemic stroke to assess if elevated LCN2 is the cause or consequence of ischemic stroke. Methods: Laboratory and anamnestic data were collected, which could have a role in development of thrombo-embolic events in patients with ischemic stroke. RNA based method was used to evaluate the relative gene expression level of LCN2. We calculated Odds Ratio (OR) and Confidence Interval (CI) for the association between LCN2 and ischemic stroke. Results: 34 samples were available for evaluation. The LCN 2 relative gene expression level was decreased in 12 cases. In this group, 91% of patients have Atrial Fibrillation (AF) at the time of hospitalisation. The mean LCN2 relative gene expression value was 64.25% (ranges: 34%-115%) in patients with AF. It was significantly lower than in patients with normal sinus rhythm (409.2%; ranges: 127%-1127%; p=0.0003). The elevated LCN2 relative gene expression level significantly (p=0.012) increases the risk of stroke (OR: 12.6) independently from other factors. Conclusions: High LCN2 expression level seems to have strong positive predictive value on ischemic stroke, and may be useful in thrombotic risk stratification of plaque vulnerability in these patients.

AbstractmicroRNAs (miRNAs) play an important role in osteoblast differentiation. However, the mechanisms of miRNAs regulating osteoblast mineralization still needs to be further cleared. Distal-less genes 2 (Dlx2) plays an important role in osteoblast differentiation. We have found that miR-539 was significantly downregulated and Dlx2 was found to be inversely correlated with miR-539 in MC3T3-E1 cell line during osteoblast mineralization. The overexpression of miR-539 significantly decreased the expression level of Dlx2 and suppressed the osteogenic marker gene expression level, alkaline phosphatase activity and matrix mineralization. Our study showed that miR-539 was a negative regulator in osteoblast mineralization and that the targeting of Dlx2 gene partly contributes to this inhibitory effect exerted by miR-539.
