"And I Let It All Out": Survivors' Sibling Sexual Abuse Disclosures.

There is consensus in child sexual abuse (CSA) literature with respect to the central role of the disclosure process. However, CSA disclosure is challenging for all children, those who have experienced intrafamilial abuse. In recent years, there has been growing research into sibling sexual abuse (SSA), which is a prevalent and severe, but also the least studied form of intrafamilial CSA.

Proliferation response of leukemic cells to CD70 ligation oscillates with recurrent remission and relapse in a low-grade lymphoma.

Interactions of the TNF-related cell surface ligand CD70 with its receptor CD27 provide a costimulatory signal in B and T cell activation. Functional CD70-CD27 interactions could contribute to lymphoma and leukemia progression. This possibility was studied using DNA microarrays on a unique case of low-grade lymphoma/leukemia characterized by recurrent cycles of acute leukemic phase alternating with spontaneous remission.
