Thermodynamic Properties for Carbon Dioxide.

We first report three reliable analytical expressions of the entropy, enthalpy and Gibbs free energy of carbon dioxide (CO) and perform predictions of these three thermodynamic quantities on the basis of the proposed analytical expressions and in terms of experimental values of five molecular constants for CO. The average relative deviations of the calculated values from the National Institute of Standards and Technology database over the temperature range from 300 to 6000 K are merely 0.053, 0.

Binding interaction of sodium benzoate food additive with bovine serum albumin: multi-spectroscopy and molecular docking studies.

Sodium benzoate (SB) is widely used as a preservative in food industry, and bovine serum albumin (BSA) is a major carrier protein similar to human serum albumin (HSA), the study of the binding between the two has great significance on human health. In this paper, we systematically investigated the binding of SB and BSA under the simulated physiological conditions combining with various common analytical methods, e.g.

Effect of Danggui Buxue Tang on immune-mediated aplastic anemia bone marrow proliferation mice.

To investigate the pharmacological effects of Danggui Buxue Tang (DBT) on immune-mediated aplasia anemia mice. The model of immune-mediated aplasia anemia mice was induced by means of (60)Co γ-ray irradiation and mixed cells of thymus and lymphnode of DBA/2 mice infusion through tail vein, the parameters tested indices were as following: blood picture, bone marrow nucleated cell count (BMNC), murine colony-forming unit-megakaryocytes (CFU-GM) of bone marrow cells, murine colony-forming unit-erthroid (CFU-E) and burst forming unit-erythroid (BFU-E). The results showed that DBT could not only withstand significantly decreation of blood cells by immune-mediated, but also stimulate on the growth of bone marrow colony cell and increase the weight of hemopoietic progenitor of bone marrow.

Equivalence of the Wei potential model and Tietz potential model for diatomic molecules.

By employing the dissociation energy and the equilibrium bond length for a diatomic molecule as explicit parameters, we generate improved expressions for the well-known Rosen-Morse, Manning-Rosen, Tietz, and Frost-Musulin potential energy functions. It is found that the well-known Tietz potential function that is conventionally defined in terms of five parameters [T. Tietz, J.

Objective: To investigate the role of connective tissue growth factor (CTGF) induced TGF-beta 1 in the transdifferentiation of human hypertrophic scar fibroblast (HSFb).

Methods: Human hypertrophic scar fibroblasts were cultured in vitro, 5 cell samples were stimulated with TGF-beta 1 (0, 2.5, 5.

[Modality and structure of Japanese eel (Anguilla japonica) during spermiogenesis].

The special process and special structure which bring organelle during the spermiogenesis of Japanese eel, Anguilla japonica were observed by scanning electron microscope and transmission electron microscope. The process which spermatoblast became sperm including four special stages, the early stage, the middle stage, the later stage and the spermic stage, then came into being a normal mature sperm. In the early stage, cell nucleus became long form gradually by the oval form.
