We present results for the σ-terms and axial charges for various hyperons and charmed baryons using Nf=2+1+1 twisted mass fermions. For the computation of the three-point function we use the fixed current method. For one of the Nf=2+1+1 ensembles with pion mass of 373 MeV we compare the results of the fixed current method with those obtained with a stochastic method for computing the all-to-all propagator involved in the evaluation of the three point functions.
