    A case of secretory breast cancer in a 6 year-old girl: is it possible to make a correct preoperative diagnosis?

    Secretory breast carcinoma constitutes the majority of breast cancers in children and young people less than 20 years of age. Noninvasive examination is particularly necessary for the diagnosis of breast carci...

    Bi-monotonic Independence for Pairs of Algebras

    In this article, the notion of bi-monotonic independence is introduced as an extension of monotonic independence to the two-faced framework for a family of pairs of algebras in a non-commutative space. The ass...

    On Free Generalized Inverse Gaussian Distributions

    We study here properties of free Generalized Inverse Gaussian distributions (fGIG) in free probability. We show that in many cases the fGIG shares similar properties with the classical GIG distribution. In par...

    Intracellular hypoxia measured by 18F-fluoromisonidazole positron emission tomography has prognostic impact in patients with estrogen receptor-positive breast cancer

    Hypoxia is a key driver of cancer progression. We evaluated the prognostic impact of 18F-fluoromisonidazole (FMISO) prior to treatment in patients with breast cancer.
