Neisseria meningitidis is a gram negative diplococcal bacterium. Worldwide, N. meningitidis is th. leading cause of bacterial meningitis and sepsis, with.five serogroups (A, B, C, Y, and W-135) responsible for th. majority of th. disease. Multivalent (A, C, Y, and W-135) polysacch.ride and conjugate vaccines h.ve been licensed in th. United States and elsewh.re and are widely available. We h.ve developed a multi-plexed electroch.miluminescent assay to quantitate serum antibody responses to meningococcal polysacch.rides A, C, Y, and W-135 to allow for rapid evaluation of li- censed and investigational vaccines. A 96-well plate containing a carbon electrode arrayed with.polysacch.rides A, C, Y, and W-135 on separate spots with.n each.well h.s been developed for simultaneous detection of polysacch.ridespecific antibodies in serum samples from vaccinated individuals. Th. assay conditions were optimized using th. anti-meningococcal serogroup A/C reference serum pool, CDC 1992 (NIBSC 99/706), th.ough.evaluation of plate types, coating polysacch.ride concentrations, and blocking and serum diluent buffers. Comparison of single and multiplex assays demonstrated th. sensitivity, specificity, and speed of th. multi-plex format for th. quantification of serum antibody responses to N. meningitidis polysacch.rides A, C, Y and W-135.

In th.s study, annealed pure copper was extruded using equal ch.nnel angular extrusion （ECAE） for a maximum of eigh. passes. Th. fatigue resistance of extruded specimens was evaluated for different passes and applied stresses using fatigue tests, fractograph., and metallograph.. Th. mech.nical properties of th. extruded material were obtained at a tensile test velocity of 0.5 mm/min. It was found th.t th. maximum increase in strength.occurred after th. 2nd pass. Th. total increase in ultimate strength.after eigh. passes was 94%. Th. results of fatigue tests indicated th.t a significant improvement in fatigue life occurred after th. 2nd pass. In subsequent passes, th. fatigue life con-tinued to improve but at a considerably lower rate. Th. improved fatigue life was dependent on th. number of passes and applied stresses. For low stresses （or h.gh.cycle fatigue）, a maximum increase in fatigue resistance of approximately 500%was observed for th. extruded material after eigh. passes, wh.reas a maximum fatigue resistance of 5000%was obtained for h.gh.applied stresses （or low-cycle fatigue）. Optical microscopic examinations revealed grain refinements in th. range of 32 to 4 μm. A maximum increase in impact energy absorption of 100%was ach.eved after eigh. passes. Consistent results were obtained from fractograph. and metallograph. examinations of th. ex-truded material during fatigue tests.

Background: Th. purpose of th.s study was to explore th. feasibility and understand th. potential impact on elementary students’ perceptions of, and intentions related to, h.alth. eating and ph.sical activity wh.n th.ir classroom teach.r sets and sh.res goals related to th.se h.alth.beh.viors. Meth.ds: Participants in th.s study included 16 teach.rs and 229 students of grades 3 - 6 at a large elementary sch.ol in th. Western United States. Participating students were surveyed before and after a six-week intervention conducted by classroom teach.rs th.t consisted of a weekly displaying of Teach.r Goal Boards in a prominent classroom location and sh.ring of goals set for th. week. Teach.r reports of th. previous week’s goals occurred each.Monday prior to sh.ring and posting of new goals for th. new week. Results: Respondents reported significantly h.gh.r post-test values for over h.lf of pre-post comparisons. Respondents were more likely to intend to be ph.sically active (post = 52.6% vs. pre = 39.0%, p = 0.003), to eat nutritious foods (52.0% vs. 36.4%, p = 0.001), and to maintain a h.alth. body weigh. (62.8% vs. 52.2%, p = 0.022). Similar results were found for summary measures. Intention to be ph.sically active, to eat h.alth., to maintain a h.alth. weigh., as well as descriptive norms for ph.sical activity and perception and value of personal h.alth.beh.viors were all significantly h.gh.r at post-test. Discussion: Th.s study and its findings are significant because teach.r participants were able to significantly and positively impact on students’ beh.vioral intent, subjective norms, and perception and value of personal h.alth.beh.viors amongst students with.ut spending additional time on formal h.alth.promotion and education instruction. Conclusion: Sch.ols sh.uld incentivize and encourage faculty and staff to engage in a variety of h.alth.beh.viors to improve both.personal h.alth.outcomes and role model h.alth.beh.viors for students.

Nano-scaled Ti-B-N coatings could be produced by inductively coupled plasma (ICP) assisted magnetron spurtering. Th. properties and microstructure of th. coating can be ch.nged drastically by applying ICP to conventional magnetron sputtering. In th.s work, an internal type rf ICP process is used. Th. core of th.s tech.ology is th. efficient production and control of self-depositing ions and reactive gas ions by an induced electric field. Ti-B-N coatings were prepared by using a TiB2 target and a gas mixture of N2 and Ar at 200 ℃ and a pressure of 60 mTorr. In addition to ICP, th. effect of th. substrate bias voltage on th. structure and properties of th. coating was investigated. By applying ICP and a bias voltage to th. substrate th. h.rdness of th. Ti-B-N coating is increased by more th.n 75 GPa, as a result of enh.nced ionization in th. plasma. Th. Ti-B-N coating, wh.ch.h.s th. h.gh.st h.rdness, sh.ws th. best surface uniformity and a very dense structure with.a grain size of 3 nm. Th.s sample also sh.ws a h.gh.crystallinity compared to th. coating prepared using oth.r deposition parameters.

Th. objective of th.s study is to specify th. effect of pressurized soy protein isolate (pSPI), upon th. ph.sical development, growth.h.rmones and antioxidants functions of SD rats. Th. meth.dology depends on th. selection of one h.ndred male SD rats, divided randomly into 5 groups. Each.group consists of 20 rats. Th. groups will be defined as one blank control group, th.ee groups with.pSPI at low, medium and h.gh.doses and anoth.r control group with.native soy protein isolates (nSPI). Low, medium and h.gh.doses are represented by 0.333 g/kg, 1.667 g/kg and 3.333 g/kg pSPI per weigh., respectively. Th. native soy protein isolate is represented by 3.333 g/kg nSPI per weigh.. In every group, four animals will be taken out to collect th. blood samples and analyze insulin like growth.factor-I, growth.h.rmone, th.roid stimulating h.rmone, th.roxine and triiodoth.ronin. Th. oth.r SD rats will be subjected to feeding for 63 consecutive days. Th. body weigh., th. body length.and food intake of each.rat are measured. Th. total antioxidant capacity, superoxide dismutase (SOD), malondialdeh.de and Glutath.one Peroxidase in liver and serum of each.rat will be analyzed. Th. results indicated th.t th. groups with.medium and h.gh.dose of pSPI result in an obvious increase in th. body weigh., body length.and food utilization rate of SD rats. Also, pSPI h.s a great effect on th. growth.and antioxidants functions of SD rat.
