MetabolomicsLC−MS Based Serum Metabolomics for Identification of Hepatocellular Carcinoma Biomarkers in Egyptian Cohort
Although hepatocellular carcinoma (HCC) has been subjected to continuous investigation and its symptoms are well-known, early stage diagnosis of this disease remains difficult and the survival rate after diagnosis is typically very low (3−5%). Early and accurate detection of metabolic changes in the...

MetabolomicsLC-MS-Based Serum Metabolomics Reveals Distinct Metabolic Signatures in Patients with Cerebral Infarction

This study applied serum metabolomics to compare patients with cerebral infarction (n=10) and controls (n=10). A total of 3,160 metabolites were identified, with distinct class distributions between groups. Cerebral infarction patients showed elevated benzene derivatives, organic acids, and bile ...

ProteomicsA Novel High-Throughput Immunoaffinity LC-MS/MS Assay for P III-NP and other Fragments of Type III Procollagen in Human Serum
The amino-terminal propeptide of type III procollagen (P-III-NP) is used with IGF-I to detect the illicit use of growth hormone and to monitor growth hormone therapy. However, the only currently available assays for P-III-NP are immunoassays, which are not well harmonized. In addition, other fragmen...
