Excess Molar Volume along with Viscosity and Refractive Index for Binary Systems of Tricyclo[5.2.1.0^2.6]decane with Five Cycloalkanes

Densities, viscosities, and refractive indices have been measured for the binary system of tricyclo­[5.2.1.0^2.6]­decane with cyclohexane, methylcyclohexane, ethylcyclohexane, butylcyclohexane, or 1,2,4-trimethylcyclohexane at temperatures <i>T</i> = (293.15 to 318.15 K) and pressure <i>p</i> = 0.1 MPa. The excess molar volumes (<i>V</i>_m^E), the viscosity deviations (Δη), and the refractive index deviations (Δ<i>n</i>_D) are then calculated. The changes of <i>V</i>_m^E and Δη with the composition are fitted to the Redlich–Kister equation. The values of density, viscosity, and refractive index increase continuously with the increase of mole fraction of tricyclo­[5.2.1.0^2.6]­decane and decrease with the rise of temperature. The <i>V</i>_m^E and Δη are all negative over the whole composition range for these five binary systems. The changes of <i>V</i>_m^E and Δη are discussed from the points of view of molecular interactions in the binary systems

Excess Molar Volume along with Viscosity, Flash Point, and Refractive Index for Binary Mixtures of <i>cis</i>-Decalin or <i>trans</i>-Decalin with C₉ to C₁₁ <i>n</i>‑Alkanes

Density, viscosity, flash point and refractive index for binary mixtures of <i>cis</i>-decalin or <i>trans</i>-decalin with nonane, decane, and undecane have been determined at pressure <i>p</i> = 0.1 MPa and different temperatures ranging from (293.15 to 323.15) K. The calculated excess molar volumes give negative values over the whole composition range for these binary systems. With the increase of mole fraction of decalin, the values of viscosity and refractive index increase continuously. The viscosity deviation and refractive index deviation are calculated, showing negative from the corresponding linear additive values. A small additional amount of the component with lower flash point leads to marked changes of flash point values of these binary mixtures

Study on the Sensitization and Antigenic Epitopes of Tropomyosin from Antarctic Krill (<i>Euphausia superba</i>)

Antarctic krill (Euphausia superba), a shrimp-like marine crustacean, has become a beneficial source of high-quality animal protein. Meanwhile, a special focus has been placed on its potential sensitization issue. In this study, a 35 kDa protein was purified and identified to be Antarctic krill tropomyosin (AkTM) by high-performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS). The purified TM showed a strong IgE-binding capacity to shrimp/crab-allergic patients’ sera, indicating that TM is the primary allergen in Antarctic krill. Simulated gastrointestinal digestion revealed that the digestion stability of TM to pepsin was higher than that to trypsin. The strong degranulation triggered by TM in RBL-2H3 cells suggested that AkTM has a strong sensitization capacity. The TM-sensitized BALB/c mice displayed severe anaphylactic symptoms; high levels of TM-specific IgE, sIgG1, and histamine; and increased IL-4, indicating that AkTM could provoke IgE-mediated allergic reactions. Bioinformatics prediction, indirect competition ELISA, and mast cell degranulation assay were used to map the antigenic epitopes of AkTM. Finally, nine peptides of T43–58, T88–101, T111–125, T133–143, T144–155, T183–197, T223–236, T249–261, and T263–281 were identified as the linear epitopes of AkTM. The findings may help us develop efficient food processing techniques to reduce krill allergy and gain a deeper comprehension of the allergenicity of krill allergens
