Poly lactic-co-glycolic acid-alginate nanocarrier for efficient drug delivery to liver cancer cells.

Efficient drug delivery systems (DDSs) can potentially replace with conventional modalities in cancer therapy, like liver cancer. In this study, a novel folic acid (FA)-functionalised and alginate (Alg)-modified poly lactic-co-glycolic acid (PLGA) nanocomposite was developed for delivery of doxorubicin (Dox) to HepG2 and Huh7 liver cancer cells. After synthesising the nanocarrier, several analytical devices, including FT-IR, DLS, TGA, and TEM, were employed for its characterisation.

PI3K/Akt/mTOR signaling pathway in cancer stem cells.

Cancer stem cells (CSCs) as a small subpopulation in tumor bulk are believed to initiate tumor formation and are responsible for the resistance to cancer therapy. The proliferation and differentiation of CSCs result in heterogeneity in a tumor which increases the chance of tumor survival and invasion. Many signaling pathways are abnormally activated or repressed in CSCs.

The effects of curcumin on the prevention of atrial and ventricular arrhythmias and heart failure in patients with unstable angina: A randomized clinical trial.

Objective: Inflammation along with oxidative stress has an important role in the pathophysiology of unstable angina which leads to acute myocardial infarction, arrhythmias and eventually heart failure. Curcumin has anti-inflammatory and anti-oxidant effects and thereby, it may reduce cardiovascular complications. This randomized controlled trial aimed to investigate the effects of curcumin on the prevention of atrial and ventricular arrhythmias and heart failure in patients with unstable angina.
