Department of Food Science and Technology: Dissertations, Theses, and Student Research
Solid fats provide critical functionality in the structuring, shortening, and stabilizing of many foods. However, their use as an ingredient is foods can present a number of challenges. The physical properties of solid fat can make them difficult to apply to or incorporate into foods consistently. On an industrial food production scale, handling of solid fats can difficult because they are often packed in heavy cubes or totes, and production delays and inefficiencies may be caused by the need to remelt the oils before use. Oils as a macronutrient also contribute a relatively high number of calories at 9 calories …

Thirty rats were randomly divided into normal control group (group A), non-paederia scandens treatment model group (group B) and paederia scandens treatment model group (group C). The expression of mRNA of TGF-β1, Smad3 and Smad7 was detected by real-time quantitative fluorescence method after 8 weeks. The results showed that, according to the ELISA data of interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), the difference between group C and group A was extremely significant (P<0.01), which is the same as between group B and group A, and that the difference between group C and group B was significant (P<0.05). The difference between group B and group A was extremely significant (P<0.01). After treatment with paederia scandens, the expression of TGF-β1 mRNA was significantly inhibited, the difference between group C and group A was significant (t=2.245, P<0.05), and the difference between group C and group B was extremely significant (t=1.142, P<0.01). After treatment with Paederia scandens, the expression of Smad3 mRNA was significantly inhibited, the difference between group C and group A was significant (t=2.149, P<0.05), and the difference between group C and group B was extremely significant (t=1.206, P<0.01). Afterwards, the expression of Smad7 mRNA was increased, the difference between group C and group A was significant (t=2.201, P<0.05), and the difference was significant between group C and group B (t=1.007, P<0.01). Paederia scandens can inhibit the expression of TGF-β1 mRNA, decrease the expression of Smad3 mRNA, and increase the expression of Smad7 mRNA. It is shown in our study that in the mechanism of liver fibrosis, there exists a linear channel effect of Smad3 mRNA-(TGF-β1 mRNA)-Smad7 mRNA.
