A genome-wide cross-phenotype meta-analysis of the association of blood pressure with migraine
Blood pressure (BP) was inconsistently associated with migraine and the mechanisms of BP-lowering medications in migraine prophylaxis are unknown. Leveraging large-scale summary statistics for migraine (Ncases/Ncontrols = 59,674/316,078) and BP (N = 757,601), we find positive genetic correlations of migraine with diastolic BP (DBP, rg = 0.11, P = 3.56 × 10−06) and systolic BP (SBP, rg = 0.06, P = 0.01), but not pulse pressure (PP, rg = −0.01, P = 0.75). Cross-trait meta-analysis reveals 14 shared loci (P ≤ 5 × 10−08), nine of which replicate (P < 0.05) in the UK Biobank. Five shared loci (ITGB5, SMG6, ADRA2B, ANKDD1B, and KIAA0040) are reinforced in gene-level analysis and highlight potential mechanisms involving vascular development, endothelial function and calcium homeostasis. Mendelian randomization reveals stronger instrumental estimates of DBP (OR [95% CI] = 1.20 [1.15–1.25]/10 mmHg; P = 5.57 × 10−25) on migraine than SBP (1.05 [1.03–1.07]/10 mmHg; P = 2.60 × 10−07) and a corresponding opposite effect for PP (0.92 [0.88–0.95]/10 mmHg; P = 3.65 × 10−07). These findings support a critical role of DBP in migraine susceptibility and shared biology underlying BP and migraine
Measurement of internal jet structure in dijet production in deep inelastic scattering at HERA
Internal jet structure in dijet production in deep-inelastic scattering is
measured with the H1 detector at HERA. Jets with transverse energies ET,Breit >
5 GeV are selected in the Breit frame employing k_perp and cone jet algorithms.
In the kinematic region of squared momentum transfers 10 < Q2 <~ 120 GeV2 and
x-Bjorken values 2.10^-4 <~ xBj <~ 8.10^-3, jet shapes and subjet
multiplicities are measured as a function of a resolution parameter.
Distributions of both observables are corrected for detector effects and
presented as functions of the transverse jet energy and jet pseudo-rapidity.
Dependences of the jet shape and the average number of subjets on the
transverse energy and the pseudo-rapidity of the jet are observed. With
increasing transverse jet energies and decreasing pseudo-rapidities,
i.e.towards the photon hemisphere, the jets are more collimated. QCD models
give a fair description of the data.Comment: 18 pages, 6 figures, submitted to Nucl. Phys.
