To express and characterize NS1 of Indonesian-specific DENV2 virus in Pichia pastoris (P. pastoris).MethodsA codon optimized synthetic gene derived from the DENV-2 NS1 amino acid sequences was synthesized commercially and inserted into the P. pastoris pPICZαA expression vector. The recombinant DENV-2 NS1 protein was purified by Ni-NTA affinity chromatography, and its antigenicity was *** recombinant DENV-2 NS1 protein was secreted as a protein with a molecular weight of ∼45 kDa, and the optimal expression condition was achieved by induction with 2% (v/v) methanol for 72 h. The purified recombinant DENV-2 NS1 protein was able to interact with a monoclonal antibody of NS1 in a commercial rapid *** resulting recombinant DENV-2 NS1 protein produced in P. pastoris KM71 is a potential candidate for use in the development of a dengue diagnostic kit and vaccine.

The objective of the study was to determine the effect of bamboo-wood layer compositions on the properties of bamboo composite lumber. Laboratory scale bamboo composite lumbers （BCLs） with four different core layer materials, i.e., bamboo strips glued vertically, jabon wood plank （Anthocephalus cadamba Miq.）, manii wood plank （Maesopsis eminii Engl.） and sengon wood plank （Falcataria moluccana （Miq.） Barneby ＆ J.W. Grimes） were fabricated using Andong bamboo （Gigantochloa pseudoarundinacea （Steud.） Widjaja） strips glued horizontally as the outer layers and Andong bamboo zephyrs used as the second and the fourth layers. BCLs were manufactured using water based polymer-isocyanate （WBPI） adhesive with the glue spread of 250 g/m2, and the cold pressing time applied was 1 h. Results showed that physical and mechanical properties of BCLs were significantly affected by the layer compositions. The BCL consisted of 100% bamboo strips exhibited higher density （0.754 g/cm3） and mechanical properties （modulus of rupture （MOR） 1,162 kgf/cm2, modulus of elasticity （MOE） 173,757 kgf/cm2, compression strength 644.7 kgf/cm2 and hardness 553 kgf）, compared to BCLs, of which the core layer was made of wood plank （density 0.533 g/cm3, MOR 648 kgf/cm2, MOE 77,893 kgf/cm2, compression strength 389.7 kgf/cm2 and hardness 355 kgf, respectively）. No delamination occurred in all samples, indicating a high bonding quality. BCL made of 100% bamboo strips had strength values comparable to wood strength class I, while BCL with core layer made of wood plank of jabon, manii or sengon had strength values similar to wood strength class III. All BCLs produced are suitable for solid wood substitute.

Statement of the Problem: Upper limb hemiparesis is a common impairment underlying disability after Stroke. Transfer of treatment to daily functioning remains a question for traditional approaches used in treatment of upper extremity hemiparesis. Approaches based on Motor Learning principles may facilitate the transfer of treatment to activities of daily living. Methodology: Forty one subjects with chronic stroke, attending department of occupational therapy, National Institute for the Orthopaedically Handicapped, Kolkata, West Bengal, India participated in a single blinded randomized pre-test and post-test control group training study. Subjects were randomized over three intervention groups receiving modified Constraint Induced Movement Therapy (n = 13), Bilateral Arm training (n = 14), and an equally intensive conventional treatment program (n = 14). Subjects in the bilateral arm training group participated in bilateral symmetrical activities, where as subjects in constraint induced movement therapy group performed functional activities with the affected arm only and conventional group received conventional Occupational Therapy. Each group received intensive training for 1 hour/day, 5 days/week, for 8 weeks. Pre-treatment and post-treatment measures included the Fugl-Meyer measurement of physical performance (FMA- upper extremity section), action research arm test, motor activity log. Assessments were administered by a rater blinded to group assignment. Result: Both m-CIMT (p = 0.01) and bilateral arm training (p = 0.01) group showed statistically significant improvement in upper extremity functioning on Action Research Arm Test score in comparison to the conventional therapy group (p = 0.33). The bilateral arm training group had significantly greater improvement in upper arm function (Proximal Fugl-Meyer Assessment score, p = 0.001);while the constraint induced movement therapy group had greater improvement of hand functions (Distal Fugl-Meyer Assessment score, p

本试验试图应用γ辐射减少真菌病原菌(奇异常喙壳和产紫青霉)引起的腐烂,以改善菠萝[Ananas comosus(L.)***]的贮藏效果。50、75、100、150和250Gy(戈瑞)的γ辐射可延长菠萝的的货架寿命。最大容许剂量约为250Gy。果实经150Gy辐射后在20—28℃下贮藏,其组织比对照好。辐射,特别是大于250Gy的辐射,会引起果皮褐变和组织软化。褐变随着辐射剂量的增大和贮藏时间的延长而加重。辐射剂量过高则加速果实腐烂。用50—250Gy辐射,然后在11—13℃下贮藏,可以减少真菌性病害和衰老引起的采后损失,并可延长货架寿命。

全球化依赖于海上运输的自由往来。国际航运是全球贸易在未来实现进一步发展的重要基础,在亚太地区尤其如此。由于以海运为基础的全球化在面对风险时具有脆弱性,它为我们同时带来了机遇与挑战。国际航运需要以稳定和安全作为保障,美国、中国和印度尼西亚等亚太地区大国各自推出了维护地区海域安全的相关战略。本文主要探讨亚太各国在这一问题上的共同关切以及东盟在促进海洋合作中扮演的角色。各国所拥有的共同关切主要源于缺乏海洋安全和治理所导致的来自海洋以及海上的挑战和威胁,如南海及马六甲海域存在的问题。为了维护良好的海洋秩序,东盟成员国应与中国建立海洋伙伴关系。东盟与中国以及亚太其他主要大国间的包容性和全面性合作,对于保障经济发展与繁荣以及维持地区的和平与稳定具有重要意义。
