Some properties of dissolved organic matter (DOM) and chromophoric dissolved organic matter (CDOM) can be easily measured directly on whole waters, while others require sample concentration and removal of natural salts.To increase CDOM content and eliminate salts, solid phase extraction is often employed.Biases following extraction and elution are
The molecular pathogenesis of hepatocellular carcinoma (HCC) is heterogeneous and extremely complex.Thus, for individual molecular targeted therapy, novel molecular markers are needed.The abnormal expression of the human homolog of Drosophila headcase (HECA homo) has been found in pancreatic, colorectal, and oral squamous cell carcinoma.Studies of
Commercially available digital stethoscopes can be used as a phonocardiograph to record heart sounds.However, procuring a costly digital stethoscope may not be possible under resource-limited conditions.A low-cost, wire connected, and mobile phone-assisted phonocardiograph has Chargers been reported previously.The aim of this study was to develop a
