This work studies some characterizations of hyponormal operators. It presents certain operator inequalities by using a modified Aluthge transform $\tilde{T}$ given as $|T|^{\frac{k}{2m}} U |T|^{\frac{k}{2m}}$, for $k \le m$, where $k,m$ are natural numbers and $U$ is a partial isometry. Under certain assumptions, together with the properties of the operator $U$, the paper concludes that the transform $\tilde{T}$ is hyponormal, $p$-hyponormal, $(p + \frac{k}{2m})$-hyponormal, and $(\frac{p+q}{p+n})$-hyponormal given that $p,q$ are positive reals.
