Impedance spectroscopy assisted by magnetic nanoparticles as a potential biosensor principle for breast cancer cells in suspension.

Breast cancer (BC) is the leading cause of cancer death in women worldwide, with a higher mortality reported in undeveloped countries. Ideal adjuvant therapeutic strategies require the continuous monitoring of patients by regular blood tests to detect circulating cancer cells, in order to determine whether additional treatment is necessary to prevent cancer dissemination. This circumstance requires a non-complex design of tumor cell biosensor in whole blood with feasibility for use in poor regions.

Assessment for self-blame and trauma symptoms during the medical evaluation of suspected sexual abuse.

The purpose of this study was to describe behavioural and emotional symptoms and to examine the effect of abuse-related factors, family responses to disclosure, and child self-blame on these symptoms in children presenting for medical evaluations after disclosure of sexual abuse. A retrospective review was conducted of 501 children ages 8-17. Trauma symptoms were determined by two sets of qualitative measures.
