Topical pimecrolimus for paediatric cutaneous mastocytosis

J. Mashiah, A. Harel, C. Bodemer, S. Hadj‐Rabia, więcej

Clinical and Experimental Dermatology > 43 > 5 > 559 - 565

Background Most cases of paediatric cutaneous mastocytosis (CM) occur before the age of 2 years, and regression occurs in only 67% of children. Given the absence of any specific therapy, CM is usually treated symptomatically. A few publications have reported the beneficial effect of calcineurin inhibitors for CM. Aim We sought to evaluate the clinical effectiveness and safety profile of topical...

Physics Letters B > 2017 > 770 > C > 50-71

The invariance of the standard model (SM) under the CPT transformation predicts equality of particle and antiparticle masses. This prediction is tested by measuring the mass difference between the top quark and antiquark (Δmt=mt−mt‾) that are produced in pp collisions at a center-of-mass energy of 8 TeV, using events with a muon or an electron and at least four jets in the final state. The analysis...

M.-A. Harel, S.M. Mudd, M. Attal

Geomorphology > 2016 > 268 > C > 184-196

The stream power law, expressed as E=KA^mSⁿ — where E is erosion rate [LT⁻¹], K is an erodibility coefficient [T⁻¹L^(1−2m)], A is drainage area [L²], S is channel gradient [L/L], and m and n are constants — is the most widely used model for bedrock channel incision. Despite its simplicity and limitations, the model has proved useful for topographic evolution, knickpoint migration, palaeotopography reconstruction,...
