BACKGROUND: Identifying disease correlated features early before large number of molecules are impacted by disease progression with significant abundance change is very advantageous to biologists for developing early disease diagnosis biomarkers. Disease correlated features have relatively low level of abundance change at early stages. Finding them using existing bioinformatic tools in high throughput data is a challenging task since the technology suffers from limited dynamic range and significant noise...

BACKGROUND: Accurate tissue sampling in nonenhancing (NE) gliomas is a unique surgical challenge due to their intratumoral histological heterogeneity and absence of contrast enhancement as a guide for intraoperative stereotactic guidance. Instead, T2/fluid-attenuated inversion-recovery (FLAIR) hyperintensity on MRI is commonly used as an imaging surrogate for pathological tissue, but sampling from this region can yield nondiagnostic or underdiagnostic brain tissue. Sodium fluorescein is an intraoperative fluorescent dye that has a high predictive value for tumor identification in areas of contrast enhancement and NE in glioblastomas...

BACKGROUND: Endoscopic ultrasound with fine-needle aspiration (EUS-FNA) is the most efficacious way to collect specimens from a solid lesion adjacent to the gastrointestinal tract and is performed with an internal stylet during puncture. However, its reinsertion into the needle is time-consuming. Controversy surrounds whether quality of cytology specimen improves with stylet use. We performed a meta-analysis comparing the use of stylet versus no stylet with EUS-FNA of gastrointestinal-related masses...

Dysregulation of long non-coding RNAs has been found in many human cancers, including colorectal cancer that is still the third most prevalent cancer worldwide and related to poor prognosis; along with this, robust testimony has identified that long non-coding RNAs can take charge of tumor suppressor genes or oncogenes. This review summarizes nowadays research achievements on the character of long non-coding RNAs in the prognosis and diagnosis of colorectal cancer. On the basis of the results acquired in the last decade, some long non-coding RNAs are rising as biomarkers of colorectal cancer for prognosis, diagnosis, even prediction of therapeutic result, and have crucial effects in the regulation of colorectal cancer cell functions such as proliferation, invasion, apoptosis, metastasis, and drug resistant ability...

BACKGROUND: Serum creatinine, urea, and cystatin-c are standardly used for the evaluation of renal function in the clinic. However, some patients have chronic kidney disease but still retain kidney function; a conventional serum index in these patients can be completely normal. Serum amino acid levels can reflect subtle changes in metabolism and are closely related to renal function. Here, we investigated how amino acids change as renal impairment increases. METHODS: Subjects were divided into three groups by renal function glomerular filtration rate: healthy controls, patients with chronic kidney disease with normal kidney function, and patients with chronic kidney disease with decreased kidney function group...

ROC curve analysis is often applied to measure the diagnostic accuracy of a biomarker. The analysis results in two gains: diagnostic accuracy of the biomarker and the optimal cut-point value. There are many methods proposed in the literature to obtain the optimal cut-point value. In this study, a new approach, alternative to these methods, is proposed. The proposed approach is based on the value of the area under the ROC curve. This method defines the optimal cut-point value as the value whose sensitivity and specificity are the closest to the value of the area under the ROC curve and the absolute value of the difference between the sensitivity and specificity values is minimum...
