Polymer nanocomposites exhibit idiosyncratic physicochemical features that cannot be achieved by the respective individual constituting materials. Owing to their unique properties, they have witnessed widespread application in numerous areas of electrochemistry such as supercapacitors, batteries, solar cells, energy storage, and electrochemical sensors. By combining polymeric materials polyaniline (PANI), polyacetylene (PAc), polypyrrole (PPy), polythiophene (PTn), or...
Abstract Cancer is one of the main causes mortality in world. Many cancer cells produce ATP through high-level lactic acid fermentation catalyzed by lactate dehydrogenase (LDH), which converts pyruvic to acid. LDH plays a dominant role Warburg effect, wherein aerobic glycolysis favored over oxidative phosphorylation. Due high production level cells, LDH-targeting could be potential treatment strategy. A few approaches, such as drug treatment, reportedly inhibited activity. In this study, we...

The preparation of microsomal membrane proteins (MPs) is critically important to proteomics. To date most research studies have utilized an ultracentrifugation-based approach for the isolation and solubilization plant MPs. However, these approaches are labor-intensive, time-consuming, unaffordable in certain cases. Furthermore, use sodium dodecyl sulfate (SDS) its removal prior a mass spectrometry (MS) analysis through multiple washing steps result loss proteins. address limitations, this...
