Src inhibitors in lung cancer: current status and future directions

Src tyrosine kinases regulate multiple genetic and signaling pathways involved in the proliferation, survival, angiogenesis, invasion, and migration of various types of cancer cells They are frequently expressed and activated in many cancer types, including lung cancer. Several Src inhibitors, including dasatinib, saracatinib, bosutinib, and KX2-391, are currently being investigated in clinical trials. Preliminary results of the use of single-agent Src inhibitors in unselected patients with lung cancer show that these inhibitors have a favorable safety profile and anticancer activity. Their combination with cytotoxic chemotherapy, other targeted therapy, and radiation therapy is currently being explored. In this review, we summarize the rationale for and the current status of Src inhibitor development and discuss future directions based on emerging preclinical data.

A comparison of the conformability of everolimus-eluting bioresorbable vascular scaffolds to metal platform coronary stents

The aim of this study was to assess the differences in terms of curvature and angulation of the treated vessel after the deployment of either a metallic stent or a polymeric scaffold device.

Argemone mexicana decoction for the treatment of uncomplicated falciparum malaria

A prospective, dose-escalating, quasi-experimental clinical trial was conducted with a traditional healer using a decoction of Argemone mexicana for the treatment of malaria in Mali. The remedy was prescribed in three regimens: once daily for 3 days (Group A; n=23); twice daily for 7 days (Group B; n=40); and four times daily for the first 4 days followed by twice daily for 3 days (Group C; n=17). Thus, 80 patients were included, of whom 80% were aged<5 years and 25% were aged<1 year. All presented to the traditional healer with symptoms of malaria and had a Plasmodium falciparum parasitaemia>2000/microl but no signs of severe malaria. The proportions of adequate clinical response (ACR) at Day 14 were 35%, 73% and 65% in Groups A, B and C, respectively (P=0.011). At Day 14, overall proportions of ACR were lower in children aged<1 year (45%) and higher in patients aged>5 years (81%) (P=0.027). Very few patients had complete parasite clearance, but at Day 14, 67% of patients with ACR had a parasitaemia<2000/microl. No patient needed referral for severe disease. Only minor side effects were observed. Further research should determine whether this local resource could represent a first-aid home treatment in remote areas.
