Topiramate was associated with weight loss in clinical trials. We summarize the evidence on the efficacy and safety of topiramate in the treatment of overweight/obesity. The databases Medline, Embase, and Cochrane were searched. Randomized controlled studies with at least 16 weeks of duration that report the effect of topiramate on weight loss and adverse events were eligible for inclusion. Ten...

We present a novel relativistic density-functional approach to modeling quark matter with mechanism mimic confinement. The quasiparticle treatment of quarks provides their suppression due large selfenergy already at the mean-field level. demonstrate that our is equivalent chiral model medium-dependent couplings. dynamical restoration symmetry ensured by construction density functional. Suppleme...

We analyze families of hybrid equations state cold QCD matter, which combine input from gauge/gravity duality and various ab initio methods for nuclear matter at low density, predict that all neutron stars are fully hadronic without quark cores. focus on constraints recent measurements by the NICER telescope radius mass millisecond pulsar PSR J0740+6620. These results found to be consistent wit...

Abstract We study the thermodynamic properties of asymmetric quark matter, large mass stars (QSs), and proto-quark (PQSs) within quasiparticle model. Considering effects temperature model can significantly influence EOS entropy strange matter (SQM), fractions in SQM, as well tidal deformability maximum PQSs along star evolution line. Our results indicate that recent discovered heavy compact PSR...

Mixed fermion-boson stars are stable, horizonless, everywhere regular solutions of the coupled Einstein-(complex, massive) Klein-Gordon-Euler system. While isolated neutron and boson uniquely determined by their central energy density, mixed configurations conform an extended parameter space that depends on combination number fermions (ultra-light) bosons. The wider possibilities offered could ...

In this work we revisit the quantum hadrodynamics (QHD) formalism to investigate hyperonic and hybrid stars with hyperon-meson couplings fixed via broken SU(6) group, in favor of a more general flavor group SU(3). We also employ an additional channel, strangeness-hidden ϕ meson, which couples only hyperons. stars, quark phase is built SU(3) NJL model vector channel Lagrangian. found that within...

The recent measurement of the mass neutron stars (PSR J1614\ensuremath{-}2230, PSR J0348+0432, MSP J0740+6620) restricts lower limit $\ensuremath{\sim}2{M}_{\ensuremath{\bigodot}}$ maximum such compact stars, making it possible for dense matter to exist in massive stars. relativistic mean-field theory with parameter sets FSUGold including kaon condensation is used describe properties $\ensurema...

In this work, a modified Nambu-Jona-Lasinio (NJL) model with proper-time regularization is employed to study the structure of nonstrange quark stars. The coupling constant four-fermion interaction in conventional NJL as $G=G_1+G_2\langle\bar{\psi}\psi\rangle$ highlight feedback propagator gluon propagator. To dependence equation state (EOS) on modification well vacuum pressure, we choose nine r...

Abstract In this work, we investigate anisotropic effects on the equations of state (EoS) used to describe neutron and quark stars in framework Rastall–Rainbow gravity. All our calculations are computed using two different EoS matter contained within star: MIT bag model for IU-FSU parameterisation standard hadronic matter. From values masses radii obtained, can conclude that pressure has signif...
