Analysis of Λ

We analyze the baryonic semilepton decay Λb→Λμ+μ- in the scalar leptoquark models with X(3,2,7/6) and X(3,2,1/6) states, respectively. We also discuss the effects of these two NP models on some physical observables. For some measured observables, like the differential decay width, the longitudinal polarization of the dilepton system, the lepton-side forward-backward asymmetry, and the baryon-side forward-backward asymmetry, we find that the prediction values of SM are consistent with the current data in most q2 ranges, where the prediction values of these two NP models can also keep consistent with the current data with 1σ. However, in some q2 ranges, the prediction values of SM are difficult to meet the current data, but the contributions of these two NP models can meet them or keep close to them. For the double-lepton polarization asymmetries, PLT, PTL, PNN, and PTT are sensitive to the scalar leptoquark model X(3,2,7/6) but not to X(3,2,1/6). However, PLN, PNL, PTN, and PNT are not sensitive to these two NP models

2,4-Dibromo-6-{(E)-[(R)-1-phenyl­ethyl]imino­meth­yl}phenol

In the title Schiff base, C15H13Br2NO, the benzene and phenyl rings form a dihedral angle of 75.18 (13)°. The N=C bond length of 1.263 (6) Å is shorter than of the N—C bond [1.476 (5) Å], indicating a double bond. In the crystal, there is some pseudosymmetry. This occurs because most of the two mol­ecules are centrosymmetrically related. The mol­ecular structure is stabilized by intra­molecular O—H⋯N hydrogen bonds

Increased serum myeloid-related protein 8/14 level is associated with atherosclerosis in type 2 diabetic patients

<p>Abstract</p> <p>Background</p> <p>Myeloid-related protein 8/14 (MRP8/14) is a stable heterodimer formed by two different calcium-binding proteins (MRP8 and MRP14). Studies have identified that MRP8/14 regulates vascular inflammation and serves as a novel marker of acute coronary syndrome. In this study, we evaluated the correlation between serum levels of MRP8/14, hsCRP, endogenous secretory receptor for advanced glycation end-products (esRAGE) and the occurrence of coronary artery disease (CAD), or carotid intima-media thickness (IMT) when CAD was not yet developed in diabetic patients.</p> <p>Methods</p> <p>Serum levels of MRP8/14, esRAGE and hsCRP were measured in 375 diabetic patients. Then the results of those who had CAD were compared against who had not. Also, we investigated the associations between above-mentioned indicators and IMT of subjects without CAD in both diabetic group and non-diabetic one.</p> <p>Results</p> <p>Serum MRP8/14 was significantly higher in CAD than in non-CAD group (9.7 ± 3.6 ug/ml vs. 8.2 ± 3.0 ug/ml, <it>P </it>< 0.001). It was associated with severity of CAD (<it>r </it>= 0.16, <it>P </it>= 0.026). In non-CAD group, MRP8/14 was associated with IMT in patients with (<it>r </it>= 0.30, <it>P </it>< 0.001) or without diabetes (<it>r </it>= 0.26, <it>P </it>= 0.015). The areas under the curves of receiver operating characteristic for CAD were 0.63 (95% CI 0.57-0.68) for MRP8/14, 0.76 (95% CI 0.71-0.81) for hsCRP and 0.62 (95% CI 0.56 -0.67) for esRAGE.</p> <p>Conclusion</p> <p>In summary, we report that diabetic patients with CAD had elevated plasma MRP8/14 levels which were also positively correlated with the severity of CAD and carotid IMT in patients without clinically overt CAD.</p

Biphenyl-3,3′,4,4′-tetra­carboxylic acid dihydrate

The asymmetric unit of the title compound, C16H10O8·2H2O, contains one-half of the centrosymmetric organic mol­ecule and one water mol­ecule. The dihedral angles between the carboxyl­ate groups and the adjacent phenyl ring are 71.31 (3) and 16.67 (3)°, while the carboxyl­ate groups are oriented at a dihedral angle of 72.01 (3)°. In the crystal structure, inter­molecular O—H⋯O and bifurcated O—H⋯(O,O) hydrogen bonds link the mol­ecules to form a three-dimensional supra­molecular network

A SIMPLE METHOD FOR MONITORING SPRINGBOARD REACTION FORCE IN GYMNASTIC VAULTING

This work was to found a new method for measuring the reaction force of springboard (BRF), which provides scientific supports to the diagnosis of take-off technique. The elastic moduli of GYMNOVA soft and hard springboards were derived by method of mechanics of material, then the springboards were tested in static, dynamic experiments and computer simulations. An equation with different coefficients for soft and hard spring boards, which describe force-displacement of the springboard, F=kx+cx was obtained and validated. This equation can be used with convenience by employing a high speed camera shooting to the springboard for rapidly monitoring the take-off BRF, and provide scientific supports in the enhancement of vaulting techniques, and in injury preventions as well
