Maize (Zeae mays L.) is a second important crop in the country and it is first staple food in high land region. The national average yield is 2.2 t/ha. About 80% maize areas falls in this region. An introduced fungus Gray Leaf Spot (GLS) caused by Cercospora zeae-maydis has caused yield loss an average of 75%. Genetic resistance has been effective control strategy to manage this disease. The main objectives of this work were to develop, evaluate and identify high yielding cultivars tolerant to GLS. Three sets of trials were conducted in Nepal and Korea. GLS evaluation trial-I consisted of 73 genotypes, GLS evaluation trial-II composed of 38 genotypes and mid altitude hybrid evaluation trial-III consisted of 12 genotypes. Exotic, semi exotic and local germplasm of different origins were used. Among these tested genotypes, tolerant genotypes were Thai 717S31-21-3×[TZMi407 × TZMi211-11- 2-1-1-B-B-B-B-B (5.2t/ha), Pioneer12 × MASynVAR-5 F2 (5.0 t/ha) and MA SynVAR-5 F2 × Thai 919 S3 4-5-4 (4.7t/ha) with GLS mean score 2.7, 1.5 and 1 respectively in trial-I. In trial-II, superior genotypes were KYM33 × TZi3 (7.6t/ha), KYM33 × TZi18 (7.5 t/ha) and KYM33 × P45 (7.4 t/ha) with GLS scores 1.4, 2.4 and 2.5 respectively. Similarly in trial-III, high yielding genotypes were MASynVAR-5 (11.0t/ha), and TZMi407×87036- 9-1-1-1-B-B-B/TZMi102×90113-5-3-2-2-B-B-B-B (9.8t/ha). These hybrids and their parents will use to introgress resistant genes to breed better tolerant maize cultivars for Nepal.

In the result of the research on the interests to the physical strength code system of boy high school (Comparison) of advancing to higher education and nonadvancing to higher education), it was possible to deduce the following conclusion and the suggestions from the theoretical background and the assumptions mentioned above forwarded by this research. 1. The understanding in the system of P.S.C. in inefficient. 2. The system failed to provide to one's strengh buiding 3. The training for P.S.C. is always not practiced consistently but being exercised on the immediate of inspection. 4. The understanding on the itemized purpose of its inspection is relatively low. 5. The inspection has something to do with the entrance examination and conderned because of the directive score points. 6. The inspection system failed to show a fairness and a lot of contradictions have been pointed out in the course of its execution. 7. In a comparison of advancing to higher education and nonadvanoing to higher education, the latter has not considered a special necessity. 8. The relative importance for the entrance examination by current inspection of P.S. has shown as fitted one. 9. It is not well comed to practice only in the training of P.S.C. at the assigned time to P.S. From the above conclusion, the following suggestions are required. 1. It is required that the system of P.S.C. is to be equally alotted to the all physical curriculum so that the guidance with the possitive plans be undertaken in the ordinal time. 2. It should not be limited of the system of P.S.C. in reflecting to the result of entrance examination for the boys of advancing to higher educations, and but considered in the dimension of national aspects, and the systematic backing policy enabling to exercise with a interest to the system of P.S.C even for the group of non-advancing for higher education be necessary. 3. A objectivity making the inspection thorough and correct in the course of execution, of the system of P.S.C. is required. 4. The fairness of inspection should be maintained by a sufficient training in advance for the staffs of the physical strength inspection and the inconsistencies should be developed. 5. The items of sport(Swiming, physical exercise, shooting etc.) beside the items of current P.S. inspection is recommended to be added. In the end, by strengthening the grade of current P.S. inspection, it is necessary to let people know that it Is very hard to get a special grade without a consistent effort in ordinary day.

Cytokine secreted by S100A9 via TLR4 in monocytes delays neutrophil apoptosis by inhibition of caspase 9/3 pathway

Lee, N.R.,Park, B.S.,Kim, S.Y.,Gu, A.,Kim, D.H.,Lee, J.S.,Kim, I.S. Saunders Scientific Publications, W.B. Saunders ; 2016 Cytokine Vol.86 No.-

Dysregulation of neutrophil apoptosis causes pathogenesis and aggravation of allergy. S100A9 exists as one of the proteins in the neutrophils, triggering inflammatory responses by activating the immune cells. In this study, we investigated whether S100A9 affects constitutive neutrophil apoptosis by activating the monocytes in normal and allergic subjects. Supernatant from human monocytic THP-1 cells after treatment with S100A9 suppressed normal neutrophil apoptosis by inhibiting the activations of caspase 9 and caspase 3. S100A9 upregulated the release of MCP-1, IL-6, and IL-8 in THP-1 cells. An increase in cytokine was suppressed by CLI-095, a Toll-like receptor (TLR) 4 inhibitor, PP2, a Src inhibitor, rottlerin, a PKCδ inhibitor, MAP kinase inhibitors, including PD98059, SB202190, and SP600125, and BAY-11-7085, an NF-κB inhibitor. Src, PKCδ, ERK½, p38 MAPK, and JNK were phosphorylated by S100A9. The phosphorylation of Src and PKCδ was suppressed by CLI-095, and the activation of ERK½, p38 MAPK, and JNK was inhibited by CLI-095, PP2, and rottlerin. S100A9 induced NF-κB activity, and the activation was suppressed by CLI-095, PP2, rottlerin, and MAPK kinase inhibitors. In normal and allergic subjects, supernatant from normal and allergic monocytes after stimulation with S100A9 suppressed normal and allergic neutrophil apoptosis, respectively; MCP-1, IL-6, and IL-8 in the supernatant was increased by S100A9. The cytokine secretion induced by S100A9 is related to TLR4, Src, PKCδ, ERK½, p38 MAPK, JNK, and NF-κB. Taken together, S100A9 induces anti-apoptotic effect on normal and allergic neutrophils by increasing cytokine secretion of monocytes. These findings may help us to better understand neutrophil apoptosis regulated by S100A9 and pathogenesis of allergic diseases.

Harmonic decomposition of two particle angular correlations in Pb-Pb collisions at s_NN=2.76 TeV

ALICE Collaboration,Aamodt, K.,Abelev, B.,Abrahantes Quintana, A.,Adamova, D.,Adare, A.M.,Aggarwal, M.M.,Aglieri Rinella, G.,Agocs, A.G.,Agostinelli, A.,Aguilar Salazar, S.,Ahammed, Z.,Ahmad, N.,Ahmad North-Holland Pub. Co 2012 Physics letters: B Vol.708 No.3

Angular correlations between unidentified charged trigger (t) and associated (a) particles are measured by the ALICE experiment in Pb-Pb collisions at s<SUB>NN</SUB>=2.76 TeV for transverse momenta 0.25<p<SUB>T</SUB><SUP>t,a</SUP><15 GeV/c, where p<SUB>T</SUB><SUP>t</SUP>>p<SUB>T</SUB><SUP>a</SUP>. The shapes of the pair correlation distributions are studied in a variety of collision centrality classes between 0 and 50% of the total hadronic cross section for particles in the pseudorapidity interval |η|<1.0. Distributions in relative azimuth Δφ=φ<SUP>t</SUP>-φ<SUP>a</SUP> are analyzed for |Δη|=|η<SUP>t</SUP>-η<SUP>a</SUP>|>0.8, and are referred to as ''long-range correlations''. Fourier components V<SUB>nΔ</SUB>≤cos(nΔφ)> are extracted from the long-range azimuthal correlation functions. If particle pairs are correlated to one another through their individual correlation to a common symmetry plane, then the pair anisotropy V<SUB>nΔ</SUB>(p<SUB>T</SUB><SUP>t</SUP>,p<SUB>T</SUB><SUP>a</SUP>) is fully described in terms of single-particle anisotropies v<SUB>n</SUB>(p<SUB>T</SUB>) as V<SUB>nΔ</SUB>(p<SUB>T</SUB><SUP>t</SUP>,p<SUB>T</SUB><SUP>a</SUP>)=v<SUB>n</SUB>(p<SUB>T</SUB><SUP>t</SUP>)v<SUB>n</SUB>(p<SUB>T</SUB><SUP>a</SUP>). This expectation is tested for 1≤n≤5 by applying a global fit of all V<SUB>nΔ</SUB>(p<SUB>T</SUB><SUP>t</SUP>,p<SUB>T</SUB><SUP>a</SUP>) to obtain the best values v<SUB>n</SUB>{GF}(p<SUB>T</SUB>). It is found that for 2≤n≤5, the fit agrees well with data up to p<SUB>T</SUB><SUP>a</SUP>~3-4 GeV/c, with a trend of increasing deviation as p<SUB>T</SUB><SUP>t</SUP> and p<SUB>T</SUB><SUP>a</SUP> are increased or as collisions become more peripheral. This suggests that no pair correlation harmonic can be described over the full 0.25<p<SUB>T</SUB><15 GeV/c range using a single v<SUB>n</SUB>(p<SUB>T</SUB>) curve; such a description is however approximately possible for 2≤n≤5 when p<SUB>T</SUB><SUP>a</SUP><4 GeV/c. For the n=1 harmonic, however, a single v<SUB>1</SUB>(p<SUB>T</SUB>) curve is not obtained even within the reduced range p<SUB>T</SUB><SUP>a</SUP><4 GeV/c.

Measurement of the relative yields of ψ(2S) to ψ(1S) mesons produced at forward and backward rapidity in p+p , p+Al , p+Au , and He3+Au collisions at _sNN=200 GeV

Adare, A.,Aidala, C.,Ajitanand, N. N.,Akiba, Y.,Alfred, M.,Andrieux, V.,Aoki, K.,Apadula, N.,Asano, H.,Ayuso, C.,Azmoun, B.,Babintsev, V.,Bai, M.,Bandara, N. S.,Bannier, B.,Barish, K. N.,Bathe, S.,Baz American Physical Society 2017 Physical Review C Vol.95 No.3

<P>The PHENIX Collaboration has measured the ratio of the yields of psi(2S) to psi(1S) mesons produced in p + p, p + Al, p + Au, and He-3+Au collisions at root S-NN = 200 GeV over the forward and backward rapidity intervals 1.2 < | y | < 2.2. We find that the ratio in p + p collisions is consistent with measurements at other collision energies. In collisions with nuclei, we find that in the forward (p-going or He-3-going) direction, the relative yield of psi(2S) mesons to psi(1S) mesons is consistent with the value measured in p + p collisions. However, in the backward (nucleus-going) direction, the psi(2S) meson is preferentially suppressed by a factor of similar to 2. This suppression is attributed in some models to the breakup of the weakly bound psi(2S) meson through final-state interactions with comoving particles, which have a higher density in the nucleus-going direction. These breakup effects may compete with color screening in a deconfined quark-gluon plasma to produce sequential suppression of excited quarkonia states.</P>
