High grade breast ductal carcinomas have high density of tumor-associated macrophages.

Background: The role of tumor-associated macrophages (TAMs) is double-natured and still controversial. Depending on different settings, macrophages may suppress or promote tumor growth. TAM density may be one of the predictive factors of treatment outcome in cancer patients.

Association of circular Klotho and insulin-like growth factor 1 with cardiac hypertrophy indexes in athlete and non-athlete women following acute and chronic exercise.

Owing to the role of insulin-like growth factor 1 (IGF-I) in cardiac hypertrophy and the ability of Klotho in inhibiting the IGF-I action, we investigated effects of exercise on plasma Klotho and IGF-I and their association with cardiac hypertrophy. In this study, 10 non-athlete and 10 athlete women underwent a Bruce test (acute exercise) and 12-weeks water aerobics training (chronic exercise). Electrocardiographic parameters, plasma IGF-I and Klotho levels were measured in different time courses.
