The role of alpha-fetoprotein (AFP) in the specific setting of the diagnosis and prognosis of patients with hepatocellular cancer (HCC) waiting for liver transplantation (LT) is still controversial. Recently, a marked interest for this marker has been reported, mainly related to its ability to predict the outcome of HCC patients after LT. The growing number of papers in PubMed indicates that AFP has begun a "second life" in the particular context of LT. Looking at the most recent International Guidelines on HCC, it looks obvious that time is ripe to reevaluate the value of AFP in relation to its prognostic ability to identify HCC patients at high-risk for drop-out before and recurrence after LT...

An ultrasensitive sandwich-type electrochemical immunosensor was developed for quantitative monitoring of Alpha fetoprotein (AFP). To achieve this objective, an incorporated signal amplification strategy of platinum nanoparticles anchored on cobalt oxide/graphene nanosheets (Pt NPs/Co3O4/graphene) was proposed by acting as the label of secondary antibodies. The prepared label not only empowered by advantages of each component but exhibited better electrochemical performance than single Pt NPs, Co3O4 and graphene, which has shown large specific surface area and good catalytic activity towards the reduction of H2O2...

BACKGROUND: Preoperative serum inflammatory markers have been correlated with outcome after resection of hepatocellular carcinoma (HCC), but studies have had conflicting results. This study aimed to evaluate the association of six inflammatory markers with recurrence-free survival (RFS), overall survival (OS), and microvascular invasion (MVI), a well-known prognostic factor. METHODS: This study investigated 370 patients who underwent resection of HCC from 1992 to 2016, retrospectively evaluating their inflammatory indices and individual components including their neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), prognostic nutritional index (PNI), aspartate aminotransferase-to-platelet ratio index (APRI), and aspartate aminotransferase-to-neutrophil ratio index (ANRI)...

Hepatocellular carcinoma (HCC) is a highly lethal malignant tumor evolved from cirrhosis. It is quite significant to seek accurate, easy markers for early warning and diagnosis of HCC. Through prospective cohort follow-up study and mass spectrometry, we discovered and verified a serum marker valuable for early warning and diagnosis. Follow-up observation was performed on cirrhosis patients. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was adopted to detect the serums of patients, and the serum polypeptides with a potential value in early HCC warning and diagnosis were screened...

Fifteen novel 1,2,3-triazole derivatives were prepared in series of synthetic steps starting from 4-amino-5-hydrazino-4H-1,2,4-triazole-3-thiol 1. The structures of the obtained compounds were verified through micoanalytical and spectral data. All the compounds were screened for their anticancer activity against liver human cancer cell lines (HEPG2) using Doxorubicin as standard. The most promising triazolothiadiazine derivative 12 was further tested for its degree of toxicity by estimating the median lethal dose (LD 50) and its antitumor activity through inhibiting the angiogenesis and progression of tumor against diethylnitrosamine (DENA)/CCl4 induced hepatocellular carcinoma (HCC) in rats...
