The optimal duration of dual anti-platelet therapy (DAPT) following percutaneous coronary intervention (PCI) is still a matter of debate. Biomarkers may help to identify patients who will benefit from extended DAPT. The aim of the study was to test the interaction between lipid parameters and platelet function in patients with coronary artery disease (CAD) on DAPT. ⋯ Within lipid parameters, only HDL-C levels are strongly associated with markers of platelet activation in CAD patients on DAPT. Accordingly, detection of dyslipidemia might indicate the need for prolongation of DAPT.

Our aim was to compare in a prospective randomized study the safety, direct results and periprocedural data of ablation using an nMARQ catheter, a PVAC catheter used with the EnSite system, or a PVAC catheter only under fluoroscopy control. ⋯ The lowest radiological exposure was observed during ablation performed with an nMARQ catheter. 3D systems reduced fluoroscopy duration and the necessity of contrast injection. The nMARQ catheter requires injection of a large volume of fluid.

Antiproliferative and apoptotic activity of glycyrrhizinic acid in MCF-7 human breast cancer cells and evaluation of its effect on cell cycle, cell migration and m-TOR/PI3K/Akt signalling pathway.
Glycyrrhizinic acid is a natural product of pharmacological relevance and its anticancer activity against breast cancer cell lines has not been evaluated. Therefore the main purpose of the present study was to investigate the anticancer effects of glycyrrhizinic acid in MCF-7 human breast cancer cells. ⋯ Glycyrrhizinic acid inhibited MCF-7 human breast cancer cell growth and therefore may prove essential lead molecule in the treatment of breast cancer.

To analyze the appropriate treatment methods or timing to use epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) and brain radiation treatment (RT) for symptomatic and asymptomatic brain metastases (BM) in patients with EGFR mutation non-small cell lung cancer (NSCLC). ⋯ Our research indicated that delayed brain RT may result in inferior iPFS in EGFR mutated NSCLC patients with asymptomatic brain metastases, but no OS benefit was obtained. In addition, our study revealed that patients treated with SRS had a significantly longer OS for symptomatic BM. Future prospective study of the optimal management strategy with WBRT or SRS and TKI for this patient cohort is urgently needed.
