Adult prematurely aging mice (PAM), characterized by inadequate stress response, show premature immunosenescence and shorter lifespan compared to adult exceptional non-PAM (E-NPAM). Aging can be influenced by lifestyle factors, such as social environment. The continuous cohabitation of female PAM with E-NPAM improved behavioral responses, immunity, redox state, and longevity of PAM, but caused deterioration in E-NPAM.

The objective of this work was to evaluate the effects of the daily intake, for a month, of a new probiotic Akkermansia muciniphila (AKK) (2 × 10 cfu/100µL PBS) on behavior, as well as function and redox state of immune cells of old female ICR-CD1 mice (OA group). For this, several behavioral tests were performed, and function and oxidative-inflammatory stress parameters of peritoneal leukocytes were analyzed in OA group, in a group of the same age that did not take AKK (old control, OC group) and in another adult control (AC) group.

Purpose: To describe the results of MRI (magnetic resonance image) guided ROLL (radioguided occult lesion localization) and SNOLL (sentinel node occult lesion localization) in the localization of residual disease after neoadjuvant chemotherapy for breast cancer, as well as assessing the surgical results obtained and disease free survival.
Methods: Prospective observational analysis of 132 patients with 136 tumors, treated with neoadjuvant chemotherapy at our hospital between 2011-2017. Residual disease was located presurgically with MRI guided ROLL/SNOLL technique.
