Objective Autoantibodies have been reported to be associated with cancers. As a biomarker, autoantibodies widely used in the early screening of lung cancer. However, correlation between and prognosis cancer patients is poorly understood, especially Asian population. This retrospective study investigated association presence outcomes Methods A total 264 diagnosed were tested for Henan Provincial...

Gastric cancer (GC) is the fourth most common cancer and the second major cause of cancer-related deaths worldwide. In our previous study, a novel and sensitive method for quantifying cell-free DNA (CFD) in human blood was established and tested for its ability to predict patients with tumor. We want to investigate CFD expression in the sera of GC patients in an attempt to explore the clinical ...

BACKGROUND For adults with chest pain, the electrocardiogram (ECG) and measures of serum biomarkers are used to screen and diagnose myocardial necrosis. These measurements require time that can delay therapy and affect prognosis. Our objective was to investigate the feasibility and utility of saliva as an alternative diagnostic fluid for identifying biomarkers of acute myocardial infarction (AM...

Lack of sensitivity and specificity of image-based breast cancer screening has urged the exploration of alternate screening modalities. Nipple fluid, which contains breast epithelial cells, is produced in small amounts in the breast ducts of nonlactating women and can be collected by noninvasive vacuum aspiration. After administration of nasal oxytocin, nipple aspiration yields sufficient mater...

Given the low incidence of pancreatic cancer in the general population, screening of pancreatic cancer in the general population using invasive modalities is not feasible. Combination of invasive screening with noninvasive biomarkers for pancreatic cancer and its precancerous lesions has the potential to reduce mortality due to pancreatic cancer. In this review, we focus on biomarkers found in ...

Recently, preparation and screening of compound libraries remain one of the most challenging tasks in drug discovery, biomarker detection, and biomolecular profiling processes. So far, several distinct encoding/decoding methods such as chemical encoding, graphical encoding, and optical encoding have been reported to identify those libraries. In this paper, a simple and efficient surface-enhance...

The implementation of large-scale mental health care requires low-cost, highaccuracy screening methods. Reporting bias cannot be eliminated from the self-administered screening methods that are currently in general use, and screening using biomarkers, which has seen remarkable developments in recent years, remains costly.Mental disorders resulting from stress alter the expression of emotion and...

Background: Circulating-Tumour-Cells (CTC) provide a blood biomarker for early carcinogenesis, cancer progression and treatment effectiveness. An increase in CTCs is associated with cancer progression, a CTC decrease with cancer containment or remission. Several technologies have been developed to identify CTC, including the validated Isolation-by-Size-of-Epithelial-Tumour (ISET, Rarecells) tec...

Discovery and identification of molecular biomarkers in large LC/MS data sets requires significant automation without loss of accuracy in the compound screening and annotation process. Here, we describe a lipidomics workflow and open-source software package for high-throughput annotation and putative identification of lipid, oxidized lipid, and oxylipin biomarkers in high-mass-accuracy HPLC-MS ...

Telomerase is a promising biomarker and a therapeutic target due to its extensive expression in human tumors such as lung cancer and breast cancer. Here, we develop a single quantum dot (QD)-based biosensor for the sensitive detection of telomerase activity. This single QD-based biosensor has significant advantages of simplicity and high sensitivity, and it can be applied for the discrimination...
