The selectivity of artemisinin-based drugs on human lung normal and cancer cells.

Artemisinin-based drugs are documented to possess anticancer potential that is selectively effective to cancer cells. However, this selectivity is disputable in different studies and the mechanism is still unclear. To clarify this discrepancy, this study employed five assays to evaluate the cytotoxic effects of artemisinin and artesunate on normal human bronchial epithelial (HBE) cells and lung adenocarcinoma A549 cells.

Clinical features of patients treated by peritoneal dialysis for over a decade.

Background: Peritoneal dialysis (PD) is well-established as renal replacement therapy in end stage renal disease and has survival rates similar or better than hemodialysis (HD) for the initial years on dialysis therapy. However retention rate is lower due to higher technique failure rates than in HD and few patients stay on PD for more than 10 years (PD). Here we investigated clinical features characterizing PD patients.

Spirals and helices by asymmetric active surface growth.

We show that spiral and helical Au nanowires can be directly grown via the active surface growth mechanism. The formation of spiral nanowires as opposed to straight nanowires is not triggered by the presence of a particular reactant, but controlled by the ratio of reactant concentrations. We propose that the asymmetric blocking of the Au-substrate interface induces imbalanced growth of the nanowire, causing it to curve.

Chronic psychological stress promotes lung metastatic colonization of circulating breast cancer cells by decorating a pre-metastatic niche through activating β-adrenergic signaling.

Numerous studies have indicated that primary tumors induce the formation of a pre-metastatic niche in distant organs by secreting tumor-derived factors. The present study shows that pre-exposure to chronic stress enhanced lung colonization efficiency by circulating tumor cells, suggesting that chronic stress critically influences pre-metastatic lungs before the arrival of disseminated tumor cells. Ablation of the sympathetic nerve function by 6-OHDA or blockage of the β-adrenergic signaling by propranolol remarkably suppressed stress-induced lung metastasis.
