Breakup and n -transfer effects on the fusion reactions Li 6,7 + Sn 120,119 around the Coulomb barrier

This paper presents values of complete fusion cross sections deduced from activation measurements for the reactions Li6+Sn120 and Li7+Sn119, and for a projectile energy range from 17.5 to 28 MeV in the center-of-mass system. A new deconvolution analysis technique is used to link the basic activation data to the actual fusion excitation function. The complete fusion cross sections above the barrier are suppressed by about 70% and 85% with respect to the universal fusion function, used as a standard reference, in the Li6 and Li7 induced reactions, respectively. From a comparison of the excitation functions of the two systems at energies below the barrier, no significant differences can be observed, despite the two systems have different n-transfer Q values. This observation is supported by the results of coupled reaction channels (CRC) calculations

A new analysis procedure to extract fusion excitation function with large beam energy dispersions: Application to the 6Li+120Sn and 7Li+119Sn

In the present paper it is described an analysis procedure suited for experiments where cross-sections strongly varying with energy are measured using beams having large energy dispersion. These cross-sections are typically the sub-barrier fusion excitation function of reactions induced by radioactive beams. The large beam energy dispersion, typical of these experiments, can lead to ambiguities in the association of the effective beam energy to the reaction product yields and consequently to an error in the determination of the excitation function. As a test case, the approach is applied to the experiments 6Li+120Sn and 7Li+119Sn measured in the energy range 14 MeV ≤ Ecm. ≤28 MeV. The complete fusion cross sections are deduced from activation measurements using the stacked target technique. The results of these experiments, that employ the two weakly-bound stable Li isotopes, show that the complete fusion cross sections above the barrier are suppressed of about 70% and 85% with respect to the Universal Fusion Function, used as a standard reference, in the 6Li and 7Li induced reactions respectively. Moreover, the excitation functions of the two systems at energies below the barrier, do not show significant differences, despite the two systems have different n-transfer Qvalue

Pleiotropic effects of anti-thrombotic therapies: have direct oral anticoagulants any anti-inflammatory effect?

Direct oral anticoagulants (DOACs) are currently recommended by European guidelines as the first line therapy for both stroke prevention in patients with atrial fibrillation (AF) and the prevention and the treatment of venous thromboembolism (VTE). Recently, it has been speculated that DOACs have anti-inflammatory capabilities in reducing the abnormal release of pro-inflammatory factors in addition to inhibiting the activation of factor X or factor II of the coagulation cascade. However, this hypothesis is based on limited pathophysiological data with small sample size, often on in vitro studies. Real-world, in vivo, and large clinical data are scarce. The aim of the present study was the evaluation of the possible anti-inflammatory and anti-proliferative effects of DOACs treatment in a cohort of patients affected by AF or VTE, by analyzing an extensive panel of cytokines and molecules involved in the process of vascular and tissue remodeling. Our data evidenced that DOACs treatment is associated with variations in systemic inflammation markers and in metalloproteinases. Further studies with larger number of patients are required to confirm these data
