A Transportation Problem with Uncertain Costs and Random Supplies
Haiying GUO,Xiaosheng WANG,Shaoling ZHOU 국제이네비해양경제학회 2015 International Journal of e-Navigation and Maritime Vol.2 No.1
Transportation problem is an optimization problem. In general, it was studied under random or uncertain condition. Considering the recent complexity, it is not enough to make should be a perfect transportation plan only based on. Usually, there is not only uncertainty but also randomness in many systems. In this paper, the aim is to investigate a transportation problem under uncertain and random environment. As a result, a conceptual uncertain random model is proposed for the problem, where the supplies are considered as random variables, and the costs and the demands are uncertain variables. By minimizing the expected value of uncertain objective function and taking confidence levels on constraints, transforming the model into a crisp mathematical form is the main conclusion. By minimizing the expected value of uncertain objective function and taking confidence levels on constraints, the above model can be turned to a mathematical form. Then transforming the model into a typical mathematical programming model is the main conclusion by using uncertainty theory and probability theory. At the end, a numerical example is given to show the feasibility of the model.

The Theoretical Calculation of Cross Section and Spectrum for n+^(238)U Reaction up to 150 MeV
Yinlu Han,Yongli Xu,Haiying Liang,Hairui Guo,Qingbiao Shen,Chonghai Cai 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.23
The fission cross sections, the double differential cross section and the energy spectra of neutron, proton, deuteron, triton, and alpha-particle emission, the prompt fission neutron spectra for n+^(238)U reaction are consistently calculated and analyzed with nuclear reaction theoretical models in the E_n ≤ 150 MeV energy range. Theoretical calculations are compared with recent experimental data and other evaluated data.

Cloning and sequence analysis of Wild Argali short palate, lung and nasal epithelium clone 1 cDNA
Wen Shen,Kaili Chen,Yanming Sun,Haiying Guo,Dongmei Chen,Yang Cao 아세아·태평양축산학회 2017 Animal Bioscience Vol.30 No.5
Objective: Experiments were conducted to clone the sequence of Wild Argali short palate, lung and nasal epithelium clone 1 (SPLUNC1) cDNA, and to lay the foundation for further study the biological function of Wild Argali SPLUNC1. Methods: The complete sequence of Wild Argali SPLUNC1 cDNA was generated by rapid amplification of cDNA ends. The entire coding sequence was inserted into the pPIC9K vector and expressed in Pichia pastoris (P. pastoris) GS115. The recombinant SPLUNC1 protein was detected by Western blot and purified by Ni2+ chelate affinity chromatography. The test of effect of the protein on Mycoplasma ovipneumoniae (MO) was performed with real-time polymerase chain reaction. Results: The Wild Argali SPLUNC1 cDNA was 1,076 bp with an open reading frame of 768 bp, which encoded a 26.49 kDa protein composed of 255 amino acids. Its amino acid sequence shared 98.4%, 96.9%, 94.5%, 90.2%, 80.8%, 78.4%, 78.3%, 72.5%, 72.3%, 68.8% identity with those of SPLUNC1 cDNA from Ovis aries (accession no. NP_001288334.1), Capra hircus (accession no. XP_005688516.1), Pantholops hodgsonii (accession no. XP_005979709.1), Bos taurus (accession no. NP_776851.1), Felis catus (accession no. XP_006929910.1), Homo sapiens (accession no. NP_001230122.1), Sus scrofa (accession no. NP_001005727.1), Chinchilla lanigera (accession no. NP_001269294.1), Mus musculus (accession no. NP_035256.2), and Rattus norvegicus (accession no. NP_742028.1), respectively. The recombinant protein corresponded to the expected molecular mass of 25.47 kDa as judged by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and it was detected in the supernatant of P. pastoris, and it could be purified. The results from the test of inhibition effect of argali recombinant SPLUNC1 protein on MO showed that the product could inhibit MO very well (p<0.01). Conclusion: The amino acid sequence of Wild Argali SPLUNC1 was different from other organisms. The recombinant SPLUNC1 protein has good biological activity.

Enhancement and Mechanism of Transdermal Absorption of Terpene-Induced Propranolol Hydrochloride
Ying Cui,Lingzhi Li,Li Zhang,Jianyu Li,Jun Gu,Haiying Gong,Peng Guo,Wei Tong 대한약학회 2011 Archives of Pharmacal Research Vol.34 No.9
For the purpose of efficient and safe transdermal administration of propranolol hydrochloride (PHCl), effects of (+)-borneol, (+)-camphor, and α-bisabolol (5 w/v%) in 66.6% ethanol solution on transdermal permeation across rat skin in vitro and their enhancement mechanism was investigated with fourier transform infrared spectroscopy, differential scanning calorimetry, and PHCl-stratum corneum binding studies. Each of (+)-borneol, (+)-camphor, and α-bisabolol significantly increased the transdermal flux of PHCl through rat skin in comparison to the control. The enhancement mechanism of the terpenes is involved with disruption of the lipid bilayer and increase of PHCl partitioning coefficient to the stratum corneum. As for α-bisabolol, the protect effect of skin from dehydration and an important reason of irritation incident were observed with differential scanning calorimetry for the first time.

Cathepsin K Activity Controls Injury-Related Vascular Repair in Mice
Hu, Lina,Cheng, Xian Wu,Song, Haizhen,Inoue, Aiko,Jiang, Haiying,Li, Xiang,Shi, Guo-Ping,Kozawa, Eiji,Okumura, Kenji,Kuzuya, Masafumi American Heart Association, Inc. 2014 Hypertension Vol.63 No.3
<P>Cathepsin K (CatK) is one of the most potent mammalian collagenases. We showed previously the increased expression of CatK in human and animal atherosclerotic lesions. Here, we hypothesized that ablation of CatK mitigates injury-induced neointimal hyperplasia. Male wild-type (CatK<SUP>+/+</SUP>) and CatK-deficient (CatK<SUP>−/−</SUP>) mice underwent ligation or a combination of ligation and polyethylene cuff-replacement injuries to the right common carotid artery just proximal to its bifurcation, and they were then processed for morphological and biochemical studies at specific time points. On operative day 28, CatK<SUP>−/−</SUP> significantly reduced neointimal formation and neovessel formation in both single- and combination-injured arteries compared with the Cat K<SUP>+/+</SUP> mice. At early time points, CatK<SUP>−/−</SUP> reduced the lesion macrophage contents and medial smooth muscle cell proliferation, the mRNA levels of monocyte chemoattractant protein-1, toll-like receptor-2, toll-like receptor-4, chemokine ligand-12, and the gelatinolytic activity related to matrix metalloproteinase-2/-9. An aorta-explant assay revealed that smooth muscle cell movement was impaired in the CatK<SUP>−/−</SUP> mice compared with the CatK<SUP>+/+</SUP> mice. In addition, the smooth muscle cells and macrophages from CatK<SUP>−/−</SUP> mice had less invasive ability through a reconstituted basement membrane barrier. This vasculoprotective effect was mimicked by Cat inhibition with <I>trans</I>-epoxysuccinyl-L-leucylamido-{4-guanidino} butane (E64<I>d</I>). These results demonstrate an essential role of CatK in neointimal lesion formation in response to injury, possibly via the reduction of toll-like receptor-2/-4–mediated inflammation and smooth muscle cell proliferation, suggesting a novel therapeutic strategy for the control of endovascular treatment–related restenosis by regulating CatK activity.</P>
