Abstract: The objective of this study is to evaluate the healthy and unhealthy behaviors as risk factors for chronic constipation and self-rated health status. Eight hundred tenth students enrolled from a university in Miaoli city, Taiwan. Chronic constipation was assessed using Chinese questionnaire. Information of unhealthy and healthy lifestyles was interviewed by constructed questionnaire. Thirty-six percentage of university students were assessed as chronic constipation. Using multivariate logistic regression adjusted for age, sex, race and BMI, we found chronic constipation significantly correlated with frequency of consumption from snack, fast food, fried food, daily consumption of water, physical activity and junk food used as regular food. Moreover, these unhealthy behaviors significantly correlated with self-rated health status. Students with chronic constipation had poor self-rated health status. It is urgent to create healthy behaviors to reduce the risk for chronic constipation or upgrade self-rated health status in university students.

Abstract: AIM: To investigate the clinical efficacy of trabeculectomy combined with phacoemulsification and intraocular lens implantation for the treatment of primary chronic angle-closure glaucoma. METHODS: A retrospective analysis was performed on 65 patients(70 eyes)with chronic angle-closure glaucoma and varying degrees of lens opacity admitted to our hospital ophthalmology from February 2011 to February 2012. Patients underwent trabeculectomy combined phacoemulsification and intraocular lens implantation. And after that patients were followed-up for at least 6 months. Postoperative visual acuity, intraocular pressure(IOP), and bleb complications were compared and analyzed. RESULTS: According to the international standard eye chart check, after 3 months follow-up, visual acuity improved 1 line accounted for 80%(56/70); After 6 months follow-up, after vision correction the vision acuity that improved 1 line accounted for 93%(65/70); after 6 months of follow-up, IOP<21mmHg, accounted for 89%(62/70); functional blebs accounted for 89%(62/70), fewer postoperative complications. CONCLUSION:Trabeculectomy combined with phacoemulsification and intraocular lens implantation in the treatment of primary chronic angle-closure glaucoma is a safe and effective surgery method and it has a good visual recovery, IOP decrease, and fewer complications.

Yu Sun,Li-Li Zhu,Huai-Hong Zhang
Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809041907
Abstract: The crystal structure of the title compound, [Co3(C5H9O2)6O(CH4O)3]Cl, consists of trinuclear CoIII complex cations and chloride anions. The CoIII cation has site symmetry m, and is coordinated by four oxygen atoms from four bridging pivalate groups, one central O anion and a methanol oxygen atom, forming a distorted octahedral geometry. The coordinated methanol molecule is located on a crystallographic special position, the C and O atoms being located on the mirror plane. The central O anion lies in the crystallographic overline6 position, and acts as a μ3-O bridge, linking three equivalent CoIII cations and generating the oxo-centered trinuclear CoIII complex. The chloride anion, which acts as the counter-ion, is located on crystallographic overline6 position. O—H...Cl hydrogen bonding between the Cl anion and hydroxyl group of the coordinated methanol molecule links the molecules into a supramolecular network.

Abstract: There are one third of synthesized proteins must be secreted to the cell surface or to the surrounding environment to acquire their native functional state. Most of them are exported by Sec translocase (secretion pathway). Sec translocase consists of a membrane embedded protein-conducting channel, termed SecYEG and a peripherally associated motor domain, the ATPase SecA. The SecDFyajC heterotrimeric membrane protein complex can facilitates protein translocation. SecB is a molecular chaperone that functions in the protein translocation pathway. SecM (secretion monitor) encoded by the 5' region of the secM-secA mRNA, which elongation arrest is required for upregulated expression of SecA. The signal sequence in the N terminus of the nascent peptide is first recognized by the signal recognition particle (SRP). SecB, the Sec-system-specific chaperone, channels the preprotein to the Sec translocation pathway and, additionally, actively targets the bound precursor to the translocase by its ability to bind SecA. The preprotein-bearing SecA then binds to the membrane, at a high-affinity SecA-binding site, SecYEG, which constitutes a channel for polypeptide movement. Continued translocation requires cycles of ATP hydrolysis by SecA, which is thought to occur in a step-wise fashion with a step of 20~30 amino acid residues.

Abstract: In the title coordination polymer, [Ag2(NCS)2(C27H26P2)2]n, two centrosymmetrically related Ag+ cations are linked by two thiocyanate anions into binuclear eight-membered macrocycles. The Ag...Ag separation within the macrocycle is 5.4400 (6) . The distorted tetrahedral coordination about each metal atom is completed by the P atoms of two bridging 1,3-bis(diphenylphosphanyl)propane ligands, forming polymeric ribbons parallel to the a axis.

无机材料学报 , 2012, DOI: 10.3724/sp.j.1077.2012.00627
Abstract: The effect of chemical etching processes on phosphate laser glass surfaces was investigated. Under different process conditions (e.g. sonication and agitation), conventionally polished and subsequently washed phosphate glass plates were treated by submerging in both HCl and KOH solution either with or without BaCl2. Subsequently, Raman spectra and X―ray photoelectron spectroscope (XPS) of the treated surfaces were measured. The precipitation of metal cations and depolymerization of the glass network structure are the two main chemical reactions in both solutions: One refers to the substitution of P―O―H for P―O―M, the other is that the Q2 tetrahedra, the basic structural unit of the original metaphosphate glass, has gradually been replaced by the Q1 or Q0 tetrahedra. Finally, the reaction models of phosphate laser glasses dissolved in both HCl and KOH solution are proposed.

Abstract: Using the technique of quantum transport of the interfering pair we examine the Hanbury-Brown-Twiss (HBT) interferometry signatures for the particle-emitting sources of pions and kaons produced in the heavy ion collisions at GSI-FAIR energies. The evolution of the sources is described by relativistic hydrodynamics with the system equation of state of the first-order phase transition from quark-gluon plasma (QGP) to hadronic matter. We use quantum probability amplitudes in a path-integral formalism to calculate the two-particle correlation functions, where the effects of particle decay and multiple scattering are taken into consideration. We find that the HBT radii of kaons are smaller than those of pions for the same initial conditions. Both the HBT radii of pions and kaons increase with the system initial energy density. The HBT lifetimes of the pion and kaon sources are sensitive to the initial energy density. They are significantly prolonged when the initial energy density is tuned to the phase boundary between the QGP and mixed phase. This prolongations of the HBT lifetimes of pions and kaons may likely be observed in the heavy ion collisions with an incident energy in the GSI-FAIR energy range.
A Putative Cell Surface Receptor for White Spot Syndrome Virus Is a Member of a Transporter Superfamily

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0033216
Abstract: White spot syndrome virus (WSSV), a large enveloped DNA virus, can cause the most serious viral disease in shrimp and has a wide host range among crustaceans. In this study, we identified a surface protein, named glucose transporter 1 (Glut1), which could also interact with WSSV envelope protein, VP53A. Sequence analysis revealed that Glut1 is a member of a large superfamily of transporters and that it is most closely related to evolutionary branches of this superfamily, branches that function to transport this sugar. Tissue tropism analysis showed that Glut1 was constitutive and highly expressed in almost all organs. Glut1's localization in shrimp cells was further verified and so was its interaction with Penaeus monodon chitin-binding protein (PmCBP), which was itself identified to interact with an envelope protein complex formed by 11 WSSV envelope proteins. In vitro and in vivo neutralization experiments using synthetic peptide contained WSSV binding domain (WBD) showed that the WBD peptide could inhibit WSSV infection in primary cultured hemocytes and delay the mortality in shrimps challenged with WSSV. These findings have important implications for our understanding of WSSV entry.

Abstract: There is a growing concern about the serious harm of radioactive materials, which are widely used in energy production, scientific research, medicine, industry and other areas. In recent years, owing to the great side effects of anti-radiation drugs, research on the radiation protectants has gradually expanded from the previous chemicals to the use of natural anti-radiation drugs and functional foods. Some reports have confirmed that anthocyanins are good antioxidants, which can effectively eliminate free radicals, but studies on the immunoregulatory and anti-radiation effects of anthocyanins from lingonberry (ALB) are less reported. In this experiment, mice were given orally once daily for 14 consecutive days before exposure to 6 Gy of gamma-radiation and were sacrificed on the 7th day post-irradiation. The results showed that the selected dose of extract did not lead to acute toxicity in mice; while groups given anthocyanins orally were significantly better than radiation control group according to blood analysis; pretreatment of anthocyanins significantly ( p < 0.05) enhanced the thymus and spleen indices and spleen cell survival compared to the irradiation control group. Pretreatment with anthocyanins before irradiation significantly reduced the numbers of micronuclei (MN) in bone marrow polychromatic erythrocytes (PCEs). These findings indicate that anthocyanins have immunostimulatory potential against immunosuppression induced by the radiation.
