AIM: To assess the extent to which a multivariate approach to modeling interrelated hematological indices provides more informative results than the traditional approach of modeling each index separately. MATERIALS & METHODS: The effects of demographics and lifestyle on ten hematological indices collected from a Dutch population-based sample (n = 3278) were studied, jointly using multivariate distance matrix regression and separately using linear regression. RESULTS: The multivariate approach highlighted the main effects of all predictors and several interactions; the traditional approach highlighted only main effects...

Biomarkers for Parkinson's disease (PD) diagnosis, prognostication and clinical trial cohort selection are an urgent need. While many promising markers have been discovered through the National Institute of Neurological Disorders and Stroke Parkinson's Disease Biomarker Program (PDBP) and other mechanisms, no single PD marker or set of markers are ready for clinical use. Here we discuss the current state of biomarker discovery for platforms relevant to PDBP. We discuss the role of the PDBP in PD biomarker identification and present guidelines to facilitate their development...

AIM: The effect of SLC28A3 on tacrolimus disposition and new-onset hypertension (NOHP) after liver transplantation (LT) remains unclear. Methodology & results: A total of 169 patients in two cohorts from the China Liver Transplant Registry database were included. Rs7853758 in recipients'SLC28A3 could predict tacrolimus pharmacokinetics in two sets. The model of donors' CYP3A5 rs776746 and recipients' CYP3A4 rs2242480 could predict tacrolimus metabolism at week 1 and the model of donors' CYP3A5 rs776746, recipients' CYP3A4 rs2242480, recipients' SLC28A3 rs7853758 and hemoglobin could predict tacrolimus disposition at weeks 2, 3 and 4...

Recent advances in mitochondrial biogenesis have provided the emerging recognition that mitochondria do much more than 'simply providing energy for cellular function'. Currently, a constantly improving understanding of the mitochondrial structure and function has been providing valuable insights into the contribution of defects in mitochondrial metabolism to various human diseases, including chronic obstructive pulmonary disease and lung cancer. The growing interest in mitochondria research led to development of new biomedical fields in the two main smoking-related lung diseases...

Liver disease is a primary cause of liver-related morbidity and mortality worldwide. Currently, histological examination is the gold standard for diagnosis and classification of liver disease; however, due to its several drawbacks, including the risk of complications and sampling variability, noninvasive diagnostic options are favorable. Exosomal miRNAs have recently been considered as an important source of medical biomarkers due to being widely distributed in body fluids. This review summarizes existing concepts related to the origin, mode of transportation and possible functions of exosomal miRNAs, and recent findings on the role of exosomal miRNAs in liver diseases and development of exosomal miRNA-based diagnostic biomarkers in the primary forms of liver diseases...

AIM: This systematic review provides a summary of the blood protein biomarkers that have been studied for the diagnosis of acute ischemic stroke. MATERIALS & METHODS: An extensive MEDLINE (using PubMed) and Web of Knowledge search was performed. From the 354 articles found, 42 were eligible for further analysis and 25 protein biomarkers were examined. RESULTS: Though many candidate blood-based protein biomarkers were examined, only two could significantly differentiate ischemic stroke patients from healthy controls, stroke mimics and hemorrhagic stroke patients...

AIM: To investigate the emphasis of oxidative stress in the pathogenesis of vitiligo through an evaluation of ischemia-modified albumin (IMA). Results/methodology: IMA was of higher statistical significance in patients than in the control group (IMA: 0.57 ± 0.2 vs 0.52 ± 0.2 ΔABSU; p < 0.0001). IMA (p < 0.0001; OR: 8.9; 95% CI = 3.1-26.1) was found as an independent predictor of oxidative stress. Increases in affected body surface area and age were found to be independent risk factors for IMA...

Angiogenesis contributes to the growth of solid tumors. Antiangiogenic agents are widely used in various cancers and considerable efforts have been made in the development of novel biomarkers that can predict the outcome of an anticancer treatment. Of those, circulating endothelial cells (CECs) and their subsets constitute a surrogate tool for monitoring disease activity. However, owing to the lack of standardization on the phenotypes and detection of CECs and their subsets, results have always been inconsistent and uninterpretable...

AIM: We aimed to clarify diagnostic and prognostic biomarker potentials of cancer-type organic anion transporting polypeptide 1B3 (Ct-OATP1B3) mRNA in colorectal cancer (CRC) patients. PATIENTS & METHODS: Ct-OATP1B3 mRNA levels in 97 CRC and adjacent normal colon tissues were measured by real-time PCR. The receiver operating characteristic curve analysis and the Kaplan-Meier curve analysis were performed to characterize its biomarker potentials. RESULTS: Ct-OATP1B3 mRNA showed noticeable diagnostic power (the area under the receiver operating characteristic = 0...

AIM: We compared three statistical methods in selecting a panel of serum lipid biomarkers for mesothelioma and asbestos exposure. MATERIALS & METHODS: Serum samples from mesothelioma, asbestos-exposed subjects and controls (40 per group) were analyzed. Three variable selection methods were considered: top-ranked predictors from univariate model, stepwise and least absolute shrinkage and selection operator. Crossed-validated area under the receiver operating characteristic curve was used to compare the prediction performance...

AIM: To investigate the changes and significance of circulating IL-39 in patients with acute coronary syndrome (ACS). PATIENTS & METHODS: Serum IL-39 levels in ACS patients and normal coronary arteries were measured. The correlations of IL-39 with high-sensitivity CRP, cTnI, N-terminal of the prohormone brain natriuretic peptide (NTproBNP) and left ventricular ejection fraction were investigated. RESULTS: The serum levels of IL-39 in ACS patients were significantly increased...

AIM: We performed a meta-analysis to determine a more precise relationship of IL-17A and IL-17F polymorphisms with cervical cancer risk. MATERIALS & METHODS: PubMed, CNKI and Wan Fang databases were searched for studies on these associations using STATA version 10.0 software. RESULTS: Five studies were included. The AG and AA genotypes and A allele of IL-17A rs2275913 were correlated with an elevated risk of cervical cancer. The TT genotype and T allele of IL-17A rs3748067 and the CC genotype and C allele of IL-17F rs763780 carried a moderate risk of cervical cancer, when compared with the wild-type genotype...

AIM: Prostate cancer and benign prostate hyperplasia (BPH) are heterogeneous disorders with high prevalence among men. The antisense noncoding RNA in the INK4 locus codes for a long noncoding RNA whose participation in cancer has been elucidated. METHOD: We analyzed rs1333045, rs4977574, rs1333048 and rs10757278 genotypes from this locus in 125 prostate cancer patients, 125 BPH patients as well as 220 normal age-matched subjects by means of tetra-primer amplification refractory mutation system PCR method...

AIM: To investigate whether plasma miR-19a can serve as a biomarker for esophageal squamous cell carcinoma (ESCC) diagnosis and prognosis. MATERIALS & METHODS: Plasma samples from 89 ESCC, 45 benign lesion patients and 80 healthy controls were subjected to RT-qPCR analyses for miR-19a. In addition, plasma samples from 30 patients were collected before and after surgery for the same analyses. RESULTS: Plasma miR-19a was significantly increased in ESCC patients compared with healthy controls...

AIM: We investigated the association of gamma-glutamyltransferase (GGT) activity with atherogenic risk factors and metabolic health status in young nondiabetic obese women. METHODS & RESULTS: In 140 obese women GGT activity was independently associated with BMI, triglyceride to high-density cholesterol ratio and homeostasis model assessment. Metabolically healthy but obese women had significantly lower GGT activity, associated with a normal insulin sensitivity, favorable lipid profile and apolipoprotein B to apolipoprotein AI ratio...
