Zwitterionization of glycine in water environment: Stabilization mechanism and NMR spectral signatures.

At physiological conditions, myriads of biomolecules (e.g., amino acids, peptides, and proteins) exist predominantly in the zwitterionic structural form and their biological functions will result in these conditions.

Men and women show similar survival rates after breast cancer.

Purpose: To compare the disease-free survival (DFS) and overall survival (OS) rates of men and women undergoing treatment for breast cancer.

Methods: A retrospective cohort study of patients with breast cancer diagnosed and treated at the Cancer Hospital III of the National Cancer Institute of Brazil, Rio de Janeiro, Brazil, between 1999 and 2013. Male breast cancer cases were matched for age, year of diagnosis, and clinical staging to three female cases (1:3).
