low-level laser therapy (lllt) provides several benefits for patients receiving orthodontic treatment. according to some literatures, orthodontic tooth movement (otm) can be enhanced but some investigators have reported contradictory results. this article reviews the literature regarding the different aspects of the use of lllt on otm and its alterations. the general data regarding the study de...

introduction: tonsillectomy is among commonest otorhinolaryngologic surgeries. many methods have been used to control post surgical pain, but despite it, pain is still one of the problems related to this operation. recently, due to the non invasiveness of low level lasers, this modality has attracted attention. the purpose of this study is to evaluate the effects of low level laser irradiation ...

Introduction. The theoretical description of leptonic, semiand non-leptonic weak decays of pseudoscalar mesons has been known to be extremly rewarding since at least 5 decades [1] in particular due to technical and numerical challenges in the description of strong interactions on the basis Quantum Chromodynamics (QCD) [2]. The experimental and theoretical study of non-leptonic K-meson decays ha...

On the basis of the results of ξ(2230) → π+π−, pp̄ and KK̄, measured by the BES Collaboration in radiative J/ψ decays, combined with the upper limit of Br(ξ → pp̄)Br(ξ → KK̄), measured by PS185 experiment, we argue that the distinctive properties of ξ(2230), the flavor-symmetric decays and the narrow partial decay widths to ππ andKK̄ as well as its copious production in radiative J/ψ decay, would st...
