BACKGROUND Micro RNAs-371-372-373 (miRNAs-371-373), originating from the same pri-miRNA transcript, are reported to be upregulated in hepatocellular carcinoma (HCC) and to be related to the regulation of hepatitis B virus (HBV) infection. Our study investigated whether pri-miRNAs-371-373 polymorphisms are associated with the risk of HCC occurrence and HBV clearance. METHODS Genetic variations...

The K+ and K0 meson mass difference induces the mixing of the a(0)(0)(980) and f(0)(980) resonances, the amplitude of which, between the K+K- and K0(-)K(0) thresholds, is large in magnitude, of the order of m(K)m(2)(K0)sqrt[-m(2)(K+)] approximately sqrt[alpha] m(2)(K), and possesses the phase sharply varying by about 90 degrees. We suggest performing the polarized target experiments on the reac...

In this article, we take the point of view that the light scalar meson a0(980) is a qq̄ state, and calculate the strong coupling constants ga0ηπ0 and ga0η′π0 with the light-cone QCD sum rules. The strong coupling constant ga0ηπ0 is a basic parameter in studying the radiative decay φ(1020) → a0(980)γ → ηπ0γ. The lower bound of the decay width Γa0→ηπ0 = 127 +120 −53 MeV is compatible with the expe...

Meson loops in the f 0 (980) and a 0 (980) radiative decays into ρ, ω Abstract. We calculate the radiative decay widths of the a0(980) and f0(980) scalar mesons into ργ and ωγ considering the dynamically generated nature of these scalar resonances within the realm of the Chiral Unitary Approach. The main ingredient in the evaluation of the radiative width of the scalar mesons are the loops comi...

The a0(980), a0(1450) and K ∗ 0(1430) decay constants are determined using a form of QCD sum rules known to produce a very accurate determination of the ρ decay constant. The ratio of a0(980) toK ∗ 0 (1430) decay constants is shown to be ∼ 0.6, ruling out both the “loosely-bound-KK̄-molecule” and Gribov minion scenarios for the a0(980). Solutions for the isovector scalar spectral function obtain...
