We establish an explicit uniform a priori estimate for weak solutions to slightly subcritical elliptic problems with nonlinearities simultaneously at the interior and on the boundary. Our explicit \ (L^ () \) a priori estimates are in terms of powers of their \ (H¹ () \) norms. To prove our result, we combine a De Giorgi-Nash-Moser iteration scheme together with elliptic regularity and the Gagliardo-Nirenberg interpolation inequality.
