For α, β > 0 and for a locally integrable function (or, more generally , a distribution) ϕ on (0, ∞), we study integral ooperators G α,β ϕ on L 2 (R +) defined by G α,β ϕ f (x) = R+ ϕ x α + y β f (y)dy. We describe the bounded and compact operators G α,β ϕ and operators G α,β ϕ of Schatten–von Neumann class S p. We also study continuity properties of the averaging projection Q α,β onto the oper...

Two new compounds 2β-acetoxy-15-phenyl-(22,25-acetoxy)-ent-labda-8(17), 13(E)-diene (9) and 2β-hydroxy-15-phenyl-(22,24,26-trimethoxy)-ent-labda-8(17),13(E)-diene (10) have been prepared by an Electrophilic Aromatic Substitution (EAS) reaction between diterpenyl allylic alcohols and 1,4-hydroquinone or 1,3,5-trimethoxybenzene using BF(3).Et(2)O as a catalyst. These compounds, along with a serie...

This note presents an update of the B → J/ψ(μμ)KS(ππ) analysis in order to obtain the LHCb sensitivity to sin(2β). We present two selection criteria, one considering only lifetime unbiased cuts and another which includes lifetime biased cuts to reduce further the background contamination. For an integrated luminosity of 2 fb and after L0 trigger, we estimate a yield of 193k events for the B → J...

The pharmacokinetics of enrofl oxacin (ENR) were investigated after intravenous (i/v) administration in inbred (n = 10) and outbred (n = 10) healthy rabbits. After i/v ENR injection the elimination half-life (t1/2β), total body clearance (ClB) and the area under the concentration vs. time curve (AUC) in inbred rabbits were 1.51 h, 28.35 ± 1.51 ml/kg/min and 3.01 ± 0.16 μg.h/ml, respectively. Th...

We discuss the uses of conversion electron pairs for extracting photon polarization information in weak radiative B decays. Both cases of leptons produced through a virtual and real photon are considered. Measurements of the angular correlation between the (Kπ) and (e+e−) decay planes in B → K∗(→ Kπ)γ(∗)(→ e+e−) decays can be used to determine the helicity amplitudes in the radiative B → K∗γ de...

BACKGROUND Deregulation of transformer 2β (Tra2β) has been implicated in several cancers. However, the role of Tra2β expression in prostate cancer (PCa) is unclear. Therefore, this study was to investigate the expression of Tra2β in PCa and evaluated its association with clinicopathological variables and prognosis. METHODS Thirty paired fresh PCa samples were analyzed for Tra2β expression by ...
