Predictive Value of Neutrophil/Lymphocyte Ratio for Efficacy of Preoperative Chemotherapy in Triple-Negative Breast Cancer

open access: yesAnnals of Surgical Oncology, 2015
BackgroundThe neutrophil/lymphocyte ratio (NLR) has been reportedly associated with prognosis in cancer patients by influencing both cancer progression and chemosensitivity. However, the correlation between NLR and the outcome of neoadjuvant chemotherapy

Negative Poisson's ratios in few-layer orthorhombic arsenic from first-principles calculations [PDF]

open access: yes, 2015
A material exhibiting a negative Poisson's ratio is always one of the leading topics in materials science, which is due to the potential applications in those special areas such as defence and medicine. In this letter, we demonstrate a new material, few-layer orthorhombic arsenic, also possesses the negative Poisson's ratio.
